Detailed Description

The invention provides a PVC foaming section bar cutting device, which is further described in detail below by referring to the attached drawings and embodiments in order to make the purpose, technical scheme and effect of the invention clearer and more clear and definite. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1 and 2, the invention provides a PVC foamed profile cutting device, which comprises a traction device 1, a cutting device 2 and a blanking device 3, which are sequentially arranged along the travelling direction of the PVC foamed profile.

Wherein, draw gear 1 can provide traction force for advancing of PVC foaming section bar in the whole PVC foaming section bar production line. In practical application, the traction device 1 may be disposed beside a PVC foamed profile cooling device (not shown in the drawings) in an existing PVC foamed profile production line. PVC material extruded by the extruder is shaped into PVC foaming section bars by a shaping machine, and the shaped PVC foaming section bars are continuously drawn to a traction device 1 after being cooled by a PVC foaming section bar cooling device, and are continuously drawn to a cutting device 2 by the traction device 1 for cutting operation.

The cutting device 2 comprises a cutting platform 201, a first driving mechanism 202 for driving the cutting platform 201 to reciprocate along the advancing direction of the PVC foamed profile, a lifting saw blade 203 capable of being shuttled on the cutting platform 201, a second driving mechanism 204 for driving the lifting saw blade 203 to lift, and a third driving mechanism 205 for driving the lifting saw blade 203 to rotate at a high speed.

Specifically, the height of the cutting platform 201 is the same as the height of the traction surface of the traction device 1, so that the PVC foamed profile on the traction device 1 can be continuously drawn onto the cutting platform 201 for cutting operation. Further, a mounting plate 4 for mounting the third driving mechanism 205 can be arranged below the cutting platform 201; in one embodiment, a drive motor may be used as the third drive mechanism 205, such that the elevator blade 203 is directly mounted on the output shaft of the third drive mechanism 205.

Lifting saw blade 203 is used for deciding the PVC foaming section bar of continuous output to make PVC foaming section bar be cut into appointed length according to the user demand. Further, in order to enable the lifting saw blade 203 to extend upwards out of the cutting platform 201 when the cutting operation is performed, the second driving mechanism 204 may be fixedly arranged below the cutting platform 201, and the second driving mechanism 204 may be a telescopic cylinder. When the second driving mechanism 204 is a telescopic cylinder, the extending end of the piston rod of the second driving mechanism 204 is connected with the bottom of the mounting plate 4, so that when the second driving mechanism 204 works, the mounting plate 4 can move up and down, and the lifting saw blade 203 connected with the output shaft of the third driving mechanism 205 can extend upwards out of the cutting platform 201 when the cutting operation is performed.

Further, the bottom of the cutting platform 201 is also connected with a mounting frame 5 for mounting the second driving mechanism 204, so that the second driving mechanism 204 and the mounting plate 4 connected with the second driving mechanism 204 can move together with the cutting platform 201, thereby ensuring that the lifting saw blade 203 rotating at high speed can move together with the cutting platform 201 during operation.

Further, the first driving mechanism 202 may be a telescopic cylinder, and a piston rod of the first driving mechanism 202 extends horizontally outwards to be connected with the cutting platform 201. When the cutting operation is performed, the first driving mechanism 202 can pull the cutting platform 201, so that the cutting platform 201 and the lifting saw blade 203 performing the cutting operation can move at the same speed along with the PVC foamed profile, and the lifting saw blade 203 can smoothly complete the cutting of the designated position of the PVC foamed profile. After a round of cutting operation is completed, the cutting platform 201 is retracted to the initial position.

The blanking device 3 comprises a blanking platform 301, a fifth driving mechanism 302 for driving the blanking platform 301 to rotate, two first travel switches 303 for detecting that the PVC foaming section bar is in place, and a material receiving platform 304 arranged below the blanking platform 301.

Specifically, the height of the blanking platform 301 is the same as that of the cutting platform 201, so that the cut PVC foamed material can smoothly travel onto the blanking platform 301 under the boosting action of the uncut PVC foamed material (boosting force provided by the traction device 1).

Further, the blanking device 3 further includes a bracket 6 for mounting the blanking platform 301, in a specific implementation, two ends of the blanking platform 301 may be rotatably connected to the bracket 6, and the fifth driving mechanism 302 may be a driving motor, so that the motor can directly drive the blanking platform 301 to rotate relative to the bracket 6.

Further, the first travel switch 303 is disposed above the blanking platform 301 along the traveling direction of the PVC foaming profile, and the first travel switch 303 may be fixed on the bracket 6, so that when the blanking platform 301 rotates, the first travel switch 303 does not rotate with the blanking platform 301, and the installation structure of the first travel switch 303 may be simplified.

Further, of the two first travel switches 303, the one closer to the cutting device 2 is the first travel switch a, and the one farther from the cutting device 2 is the first travel switch B.

After each cutting operation by the lifting saw blade 203, the cut PVC foamed material travels to the blanking platform 301 under the assistance of the uncut PVC foamed material. During the process that the cut PVC foaming section bar advances on the blanking platform 301, the front end of the PVC foaming section bar is firstly contacted with a first travel switch A; when the front end of the cut PVC foamed profile contacts with the first travel switch a, the first travel switch a is triggered, so that the first driving mechanism 202, the second driving mechanism 204 and the third driving mechanism 205 receive the working signal at the same time, and the lifting saw blade 203 performs the next cutting operation on the continuously produced PVC foamed profile. Further, in order to keep the length of the PVC foam profile after each cutting consistent, when the cutting platform 201 is retracted to the initial position, the transverse distance between the contact of the first travel switch a and the lifting saw blade 303 should be the length of the cut PVC foam profile.

In the process of carrying out the next round of cutting operation by the lifting saw blade 203, the rear end of the PVC foamed profile obtained by the previous round of cutting still can continue to advance due to the contact with the rear end of the PVC foamed profile which is not finished with the cutting, and after the front end of the PVC foamed profile contacts with another first travel switch 303 (for convenience of description, the first travel switch 303 is referred to as a first travel switch B), the first travel switch B is triggered, and the fifth driving mechanism 302 can receive a working signal, so that the blanking platform 301 rotates, and the cut PVC foamed profile on the blanking platform 301 falls into the material receiving platform 304, thereby realizing the blanking of the PVC foamed profile. Further, the distance between the two first travel switch 303 contacts is smaller than the length of the cut PVC foaming section, so that the cut PVC foaming section can be discharged before a new round of PVC foaming section cutting operation is performed, and the front end of the uncut PVC foaming section is contacted with the first travel switch A and triggers the first travel switch A, so that the cutting length of the PVC foaming section can be accurately controlled.

The PVC foaming profile cutting device is provided with the cutting device 2 which is matched with the traction device 1 to work, when the cutting device 2 works, the cutting platform 201 and the saw blade can move together with the PVC foaming profile which is continuously pulled out by the traction device 1, when the cutting of the designated position of the PVC foaming profile is successfully completed, the PVC foaming profile which is continuously produced can be cut, so that the requirement of the continuous production operation of the PVC foaming profile is met, the blanking device 3 is also arranged, when the blanking device 3 works, the blanking platform 301 can rotate and enables the cut PVC foaming profile to complete blanking, and simultaneously, by means of the first travel switch arranged on the blanking device 3, the cutting operation and the blanking operation of the PVC foaming profile can be matched with each other by utilizing the triggering of the cut PVC foaming profile on the first travel switch, the manual operation is not needed, the automation degree of the production operation is higher, and because the PVC foaming section bar can carry out the unloading automatically after cutting, therefore the production efficiency of PVC foaming section bar can obviously improve.

As shown in fig. 3, 4, 6 and 7, in another preferred embodiment of the present invention, a plurality of fifth driving mechanisms 302 are provided, and the fifth driving mechanisms 302 are telescopic cylinders. Furthermore, the blanking device 3 further includes a side frame 7 (the side frame 7 may be a part of the bracket 6), and a support plate 8 is disposed on the side frame 7; unloading platform 301 is when not rotating, one side bottom and the backup pad 8 contact of unloading platform 301, and the opposite side bottom of unloading platform 301 receives the support of the piston rod of fifth actuating mechanism 302 to fifth actuating mechanism 302 slope and parallel locate the below of unloading platform 301, can steadily be in the horizontality when making unloading platform 301 not rotate like this, so that the PVC foaming section bar that cuts can advance smoothly to unloading platform 301 on.

As shown in fig. 6 and 7, in order to enable the blanking platform 301 to rotate and blanking when the blanking device 3 performs the blanking operation, in the embodiment, the extending end of the piston rod of the fifth driving mechanism 302 is hinged upward to the bottom of the blanking platform 301, and the lower end of the fifth driving mechanism 302 is hinged to the lower portion of the side frame 7, so that when the piston rod of the telescopic cylinder is telescopic, the blanking platform 301 can rotate relative to the side frame 7. After the piston rod of the telescopic cylinder of the blanking platform 301 in the horizontal state is contracted, the blanking platform 301 can rotate to one side where the material receiving platform 304 is located, so that the PVC foaming sectional material on the blanking platform 301 falls into the material receiving platform 304, and blanking of the PVC foaming sectional material is realized.

As shown in fig. 6, further, a support frame 9 for supporting the material receiving platform 304 is disposed below the material receiving platform 304, and a cushion pad 10 is disposed on a contact surface between the support frame 9 and the bottom of the material receiving platform 304, so that the impact resistance of the material receiving platform 304 can be improved, and the situation that the cut PVC foam profile falls on the material receiving platform 304 to deform the material receiving platform 304 is avoided.

As shown in fig. 7, further, a magnetic suction seat 12 is disposed at an upper portion of the side frame 7, the magnetic suction seat 12 is used for mounting the first travel switch 303, and the magnetic suction seat 12 is selected to facilitate an operator to adjust a distance between the two first travel switches 303 and a lateral distance between the first travel switch 303 and the lifting saw blade 203 according to production operation requirements.

Further, the first travel switch 303 is a roller type travel switch, and a rotating arm of the roller type travel switch is disposed downward and is connected with a blocking piece 13.
