As shown in fig. 1 to 7, the rolling molding machine 100 for a shaped lollipop includes: the automatic candy making machine comprises a frame 101, a candy rod roller 102, a candy roller 103, a hopper 104, an anti-jamming roller 105, a guide rod 106, a limiting piece 107, a roller 108, an inserting rod 109, a rod inserting cam 110, a guide piece 111 and a driving device.

Wherein the frame 101 is used for supporting the whole special-shaped lollipop rolling forming machine 100 so that the components forming the special-shaped lollipop rolling forming machine 100 form an organic whole. And the driving device is at least used for driving the candy bar roller 102, the anti-jamming roller 105 and the candy roller 103 to rotate. The driving device can use a motor as a power source, and adopts various transmission modes such as chain transmission, gear transmission, belt transmission and the like, which are well known by the technical personnel in the field, and are not the key points for improving the technical scheme of the application, and the details are not repeated.

Specifically, the candy bar roller 102, the guide bar 106, the limiting member 107, the roller 108, the insertion bar 109, the insertion bar cam 110 and the guide member 111 may implement the insertion bar 109 process of the special-shaped lollipop rolling and forming machine 100 of the present application, and the combination thereof may be defined as a lollipop bar insertion device; the sugar bar drum 102, the hopper 104, and the anti-jamming roller 105 may implement the process of the present invention for the shaped lollipop roll forming machine 100 to load the lollipop bars into the slots 112 of the sugar bar drum 102 one by one, and their combination may be defined as a sugar bar anti-jamming conveying mechanism.

Specifically, the peripheral surface of the candy bar drum 102 is formed with slots 112 for receiving lollipop bars; while the candy bar drum 102 is also formed with a guide hole 113. The candy bar drum 102 is rotatably connected to the frame 101, and the slot 112 and the guide hole 113 are both substantially parallel to the axis of rotation S1 of the candy bar drum 102.

Alternatively, the candy bar drum 102 may be rotatably connected to the frame 101 by a shaft member and corresponding bearings, and the candy bar drum 102 may be driven to rotate by a transmission such as a pulley or a sprocket mounted on the shaft member. Preferably, a belt drive is used to drive the candy bar drum 102 to rotate, so that the drive is smooth.

In addition, a hollow space is formed on the side of the candy bar drum 102 facing the guide 111 to avoid the space required for the guide 111. Preferably, the guide holes 113 and the slots 112 are correspondingly arranged in the circumferential direction of the candy bar drum 102.

The peripheral surface of the sugar roller 103 is formed with a trough 114 for receiving lollipop material, the sugar roller 103 rotates synchronously with the candy bar roller 102, and the trough 114 of the sugar roller 103 also corresponds to the slot 112 of the candy bar roller 102. The function of the mass roller 103 is to contain the mass so that the lollipop sticks can be inserted into this portion of the mass. Specifically, in order to realize the forming of the sugar material, the forming roller 115 further comprises at least one forming roller 115, the forming roller 115 is also provided with a forming groove 116, the forming roller 115 can realize the forming of the sugar material after the forming groove 116 and the mixing groove 114 are butted when rotating, the principle is similar to the die clamping forming, and the difference is that the line operation is realized by staggering the forming groove 116 and the mixing groove 114 along with the rotation after the forming groove 116 and the mixing groove 114 are butted.

The hopper 104 has a transport ramp 128 extending to the outer periphery of the candy bar drum 102. In operation, the lollipop sticks are placed into the hopper 104 and, under the influence of gravity, they follow the transport ramp 128 to the end of the transport ramp 128, while the stick roller 102, by rotating upward (clockwise in FIG. 1), allows the sticks to engage the slots 112 and be carried to a predetermined position for insertion of the stick 109.

Preferably, the end of the transport slope 128 of the hopper 104 corresponds approximately to the diameter of the circumference of the candy bar drum 102 parallel to the horizontal, and the end may be located near the top of the diameter or near the bottom of the diameter with a deviation angle of no more than ± 10 degrees, since the open area of the slot 112 in the direction of the hopper 104 decreases whether it is too up or down.

Similarly, the forming drum 115 and the candy drum 103 should be positioned higher than the diameter of the circumference of the candy bar drum 102 parallel to the horizontal.

Anti-jamming roller 105 is rotatably disposed above transport ramp 128 and at least partially in contact with sugar bar drum 102. The anti-jamming rollers 105 can be driven by a drive means which rotates in the same direction as the candy bar drum 102, although their axes of rotation are parallel. Due to the direction of rotation and friction, if multiple lollipop sticks are inserted into the same slot 112, the anti-jamming roller 105 will cause the extra lollipop sticks to fall back into the hopper 104 by friction. Thereby preventing the lollipop stick from being blocked to influence the whole processing procedure.

Alternatively, the outer circumference of the candy bar drum 102 is configured to coincide with one cylindrical body portion; the axis of rotation of the anti-jam roller 105 is located outside or on the cylinder of the candy bar drum 102. The transport slope 128 is parallel to the rotation axis S2 of the jam-preventing roller 105. Thus facilitating the posture adjustment of the lollipop stick.

The hopper 104 further comprises: two bucket walls 117 are provided on both sides of the conveying slope 128, respectively. And the bucket wall 117 is perpendicular to the transport ramp 128. The walls 117 limit the position of the lollipop sticks from both sides, helping to fit into the slots 112 in a desired manner, and increasing the number of lollipop sticks that can be placed into the hopper 104 at one time due to the presence of the walls 117.

The size of the jam-preventing roller 105 in the direction of its rotation axis is equal to or greater than the distance between the two bucket walls 117. The insertion groove 112 extends in a direction parallel to the rotational axis of the jam-preventing roller 105. Meanwhile, the anti-jamming roller 105 is at least partially a cylinder having a radius equal to the distance from the axis of rotation of the anti-jamming roller 105 to the cylindrical outer peripheral surface of the candy bar drum 102. The radius of the cylinder of the anti-seize roller 105 is smaller than the radius of the cylinder of the plunger 109 drum. Such an arrangement can improve the effectiveness of the anti-jam roller 105. The anti-jamming roller 105 may rotate at a higher speed than the candy bar drum 102.

According to the technical scheme, in order to realize the process of inserting the rod 109, the following scheme is adopted: the guide rod 106 is slidably inserted into a guide hole 113 provided in the candy bar drum 102; a stopper 107 is fixed at the exposed end of the guide bar 106; a roller 108 rotatably connected at an end of the guide bar 106 and located outside the stopper 107; and an insert rod 109 connected with the guide rod 106 so that the insert rod 109 and the guide rod 106 can synchronously slide relative to the candy bar roller 102. The guide bar 106, the stop 107, the roller 108 and the insert bar 109 form a unit that slides relative to the candy bar drum 102. In a specific embodiment, the limiting member 107 is sleeved on an end of the guiding rod 106, the inserting rod 109 is also connected to the limiting member 107 to form a mounting hole, and the roller 108 is rotatably connected to an outer side of the limiting member 107.

The plunger cam 110 is provided with a contact surface for contacting the roller 108 to force the guide bar 106 and plunger 109 assembly to move closer to the candy bar drum 102. The plunger cam 110 is also driven by the driving means to rotate relative to the frame 101, and its rotation axis is S3. In operation, the roller 108 rotating to the rod inserting cam 110 is contacted by the rod inserting cam 110, and along with the rotation of the candy bar roller 102 and the rotation of the rod inserting cam 110, the roller 108 receives a force to make it close to the candy bar roller 102, and the guide rod 106, the limiting piece 107, the roller 108 and the rod inserting 109 form a whole body, and the whole body slides under the guide of the guide rod 106, so that the rod inserting 109 drives the candy bars in the slot 112 to be inserted into the candy materials in the candy material roller 103 to complete the rod inserting 109 process. The roller 108 functions to provide a contact surface on the one hand and to reduce impact and friction when in contact with the plunger cam 110 on the other hand, improving the service life, especially when the plunger cam 110 is divided into two contact areas to allow rapid impact.

As a specific scheme, in order to enable the guide rod 106, the limiting piece 107, the roller 108 and the insert rod 109 which are pressed to the candy bar roller 102 by the insert rod cam 110 to form an integral reset, the guide piece 111 is fixedly connected with the machine frame 101 so as to enable the candy bar roller 102 to rotate relative to the guide piece 111; the guide member 111 is formed with a guide rail surface 118, and the retaining member 107 is formed with a retaining portion capable of contacting the guide rail surface 118 so that the guide bar 106 can be pulled out to a predetermined position when the candy bar drum 102 rotates.

More specifically, the projection of the guide track surface 118 onto a plane perpendicular to the axis of rotation of the candy bar drum 102 is circular. The guide track surface 118 has a distal end furthest from the end surface of the sugar cane roller 102 and a proximal end closest to the end surface of the sugar cane roller 102, the guide track surface 118 smoothly transitioning between the distal and proximal ends; the guide rail surface 118 is formed by a straight line segment perpendicular to the rotation axis of the candy bar drum 102 as a generatrix and a circular curve obliquely intersecting the rotation axis of the candy bar drum 102 as a conductive line.

In the circumferential direction, the guide track surface 118 of the guide 111 corresponds to the position of the plunger cam 110, and when the plunger cam 110 is in the position, the guide track surface 118 is located at the proximal end so that the guide 111 and the like have a space for movement, and when the insertion rod 109 is once completed, the guide track surface 118 causes the stopper 107 to be forced by a reaction force along with the rotation of the candy bar drum 102 so that the entire guide 111 and the like are continuously separated from the candy bar drum 102.

Specifically, in order to achieve a better impact effect of the plunger cam 110, the plunger cam 110 includes: a wheel body 119 and a drive shaft 129. Wherein, the wheel body 119 is formed with: a first contact structure 120 and a second contact structure 121. Wherein the first contact structure 120 forms a first contact surface 122; the second contact structure 121 forms a second contact surface 123; the first contact surface 122 and the second contact surface 123 are both arc-shaped slopes. The end of the drive shaft 129 is connected to the wheel 119, and the drive shaft 129 is at least partially a solid of revolution, the axis of which defines the drive shaft 129 line. The windmill type cam structure of the plunger cam, which is composed of the first contact structure and the second contact structure, can form side contact molding with the plunger, so that the defect that the traditional structure is in hard contact and the push rod is pushed to reciprocate by depending on a lubricant is overcome.

More specifically, the first contact structure 120 and the second contact structure 121 are the same structure. A plane perpendicular to the drive axis 129 line is defined as a projection plane; the projection outlines of the first contact structure 120 and the second contact structure 121 on the projection plane are respectively positioned on two sides of a median line L, and the projection point of the drive shaft 129 line on the projection plane is positioned on the median line L. The projection profile of the first contact structure 120, which is obtained by taking the bisector L as a symmetry line, is symmetrical to the projection profile of the second contact structure 121 with respect to a perpendicular line M perpendicular to the bisector L, and the projection point of the drive axis 129 line on the projection plane is located on the perpendicular line M. The edge of the projected contour of the first contact structure 120 on the projection surface comprises: a first circular arc edge 124 and a second circular arc edge 125. Wherein, the projection point of the circle center a of the first arc edge 124 is located at one side of the middle line L; the projection point of the center b of the second arc edge 125 is located on the other side of the middle line L. The radius of the first arc edge 124 is greater than the radius of the first arc edge 124.

The second contact structure 121 comprises, at the edge of the projection profile of the projection surface: a third arc edge 126 and a fourth arc edge 127. Wherein, the projection point of the center c of the third arc edge 126 is located at one side of the middle line L; the projection point of the center d of the fourth arc edge 127 is located on the other side of the middle line L. The radius of the third arc edge 126 is larger than the radius of the fourth arc edge 127. The centers of the first arc edge 124 and the second arc edge 125 are both located on one side of the perpendicular line M; the centers of the third arc edge 126 and the fourth arc edge 127 are both located on the other side of the perpendicular line M.
