Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

This take-up needle formula to drip gluey mould shedder, as shown in fig. 1-3, including the joint body 1 that is connected with first linear actuator, but sliding connection has driving piece 2 on the joint body 1, 2 one end drives and is connected with at least one swinging boom 3 of driving piece, the other end is connected with second linear actuator, 3 rotatable coupling of swinging boom on connecting body 1, swinging boom 3 on be connected with one at least and take-up needle 4, drive take-up needle 4 and make when driving piece drive swinging boom 3 rotates and prick the action.

After the soft rubber product is cooled and formed in the glue dripping mold, the first linear driver drives the end part, close to the cantilever needle, of the joint body 1 to the soft rubber product, the second linear driver drives the driving piece 2, the rotating arm 3 is driven to rotate through the driving piece 2, the wrist action of an operator is simulated, and the cantilever needle is driven to perform arc-shaped pricking and pricking actions. In the earlier stage of action of the picking needle 4, the needle head of the picking needle 4 obliquely penetrates into the soft rubber product, so that the picking needle is ensured to penetrate into the soft rubber product under smaller resistance; after the needle head of the cantilever needle 4 rotates to the lowest point along with the rotating arm 3, the needle head of the cantilever needle 4 moves towards the direction away from the soft rubber product, and the acting force of the glue dripping mold is kept away from the soft rubber product by the needle rod of the cantilever needle 4, so that the soft rubber product is separated from the cavity of the glue dripping mold in a loosening manner, and the soft rubber product is difficult to separate from the cantilever needle.

When the soft rubber product is separated from the glue dripping mold, the first linear driver is utilized to move the joint body 1 away from the glue dripping mold, the cantilever needle 4 is driven to carry the soft rubber product to further away from the glue dripping mold, and the soft rubber product is further separated from the glue dripping mold completely. After the soft rubber product is completely separated from the glue dripping mold, the second linear driver drives the driving piece 2 to move reversely, and drives the rotating arm 3 to move reversely, so that the pick-up needle 4 moves reversely along the original track, and the soft rubber product is separated from the pick-up needle and drops.

Those skilled in the art will appreciate that the first linear actuator and the second linear actuator may be linear air cylinders, linear motors, etc. that provide linear output.

Specifically, as shown in fig. 5, the driving member 2 includes a driving portion 5 and a driving rod 6 disposed at an end close to the rotating arm 3, the driving portion 5 includes a connecting portion 7, and in this embodiment, two driving strips 8 are disposed on the connecting portion 7. One or more driving strips 8 can be designed by those skilled in the art according to the requirement of the demolding force so as to drive the rotating arms with different numbers to drive the multiple picking heads to pick and fix the soft rubber product.

Further, as shown in fig. 4, the driving portion 5 is provided with at least one rack 9 distributed along the movable direction of the driving member 2, one end of the rotating arm 3 near the rack 9 is provided with a gear portion 10 corresponding to the rack, the rack 9 is in meshing transmission connection with the gear portion 10, and the rack 9 is arranged on the driving bar 8. In this embodiment, there are two and relatively parallel driving strips 8, the two driving strips are located on different planes and are staggered and distributed relatively, and the rack 9 is disposed on the driving strips 8.

When second linear actuator pulling actuating lever 6 was to the direction motion of keeping away from swinging boom 3, link firmly integrative connecting portion 7 and drive division 5 together with actuating lever 6 and remove to the direction of keeping away from swinging boom 3, drive rack 9 to the direction motion of keeping away from swinging boom 3, at this moment, gear portion 10 with rack 9 meshing receives rack 9 to drive around the pin joint point rotatory with connecting body 1, the one end that gear portion 10 was kept away from to swinging boom 3 pricks flexible glue goods to being close to the motion of dripping glue mould direction pitch arc. Similarly, when the second linear driver pushes the driving rod 6 to move towards the direction close to the rotating arm 3, the end of the rotating arm 3 far away from the gear part 10 moves towards the direction far away from the soft glue product in an arc manner to exit.

Furthermore, the rack 9 is arranged inside the driving strip 8, and the two rotating arms 3 are respectively connected with the corresponding driving strips 8 in the same plane and are arranged in a staggered way. The structure is compact, the volume is reduced, and the glue dripping mold is more flexible when being used for the intensive glue dripping mold.

The skilled person should easily obtain the technical teaching, design many driving strips, arrange and connect on connecting portion 7 in the form of array, driven by the same actuating lever 6, rack 9 sets up and is radial outside driving strip 8, and each picking needle 4 needle point inwards forms the needle array, improves the locking ability of picking needle 4, prevents when the drawing of patterns, the flexible glue goods is not separated with the picking needle when drawing of patterns.

Preferably, the rotating arm 3 is provided with a needle clamping groove 14, the needle clamping groove 14 is arranged in an inward inclined manner, and the picking needle 4 is detachably arranged in the needle clamping groove 14. The needle clamping groove 14 limits the position of the picking needle 4, fixes the picking needle 4, prevents the picking needle 4 from shifting when penetrating into a soft rubber product, influences the penetration of the picking needle, and greatly reduces the risk that the stress of the picking needle 4 is broken. The needle points of the cantilever needles 4 are inward and downward to form a needle array, so that the needle array is favorable for penetrating soft rubber products, the binding force of the cantilever needles 4 to the soft rubber products is enhanced on the back surface when the soft rubber products are pulled for demoulding, and the soft rubber products are prevented from being separated from the cantilever needles when the demoulding is not completed.

Furthermore, a connecting hole 15 is formed in the rotating arm 3, a needle fixing column 16 penetrates through the connecting hole 15, a needle penetrating hole is formed in the needle fixing column 16, the picking needle 4 penetrates through the needle penetrating hole and is tensioned by the needle fixing column 16 to abut against the rotating arm 3, and a fastening nut is arranged on one side, far away from the picking needle 4, of the needle fixing column 16. When the picking needle 4 is damaged and the use is influenced, the fastening nut is unscrewed, and after the fastening nut is taken down, the needle fixing column 16 is pushed out from the direction close to the needle clamping groove 14, so that the picking needle 4 is replaced, and the disassembly, assembly and replacement are convenient.

Preferably, the picking needle 4 tip is hidden in the joint body 1 when the picking needle is opened. When the picking needle 4 is driven to retract upwards, the soft rubber product is blocked by the joint body 1 and is further forced to be separated from the picking needle 4, so that the falling is facilitated.
