Description

Technical Field

[0001] This utility model relates to the field of plastic product spraying technology, and in particular to a spraying support fixture for plastic products. Background Technology

[0002] The common method for spraying plastic products is to classify the plastic parts and then spray them separately according to their categories. These products are usually equipped with painting and drying equipment. During the spraying process, the plastic products need to be placed on a support fixture and then sprayed with the spraying equipment.

[0003] Common plastic product spraying support fixtures only include height adjustment functionality, allowing for adjustment of the storage height of plastic products. However, they lack the function of changing the surface, which cannot guarantee the cleanliness of the plastic product placement surface. This can easily lead to paint residue on the placement surface of the fixture after the previous plastic product has been sprayed, causing subsequent plastic products with different spraying requirements to be contaminated with the paint on the placement surface, thus affecting the spraying quality.

[0004] Therefore, given that the aforementioned adhesive application device for shoe processing lacks the function of dynamically switching the placement surface, resulting in residual paint from previous spraying adhering to the tooling surface and causing cross-contamination between different batches of products, leading to a decrease in coating uniformity and a reduction in yield, there is an urgent need to design a new type of spraying support tooling for plastic products. Utility Model Content

[0005] To overcome the problem that common shoe processing gluing devices lack the function of dynamically switching the placement surface, resulting in residual paint from previous spraying adhering to the tooling surface, causing cross-contamination between different batches of products, and causing a decrease in coating uniformity and yield rate.

[0006] The technical solution of this utility model is as follows: a spraying support fixture for plastic products, including a support frame; it also includes a support box, a rear groove, a front groove, a mounting plate, a motor, a take-up shaft, a rotating shaft, and a plastic roll. The support box is set inside the support frame. A rear groove is opened on the rear side of the top of the support box, and a front groove is opened on the front side of the top of the support box. A mounting plate is set on the right side of the top of the support box. A motor is set at the front end of the right side of the mounting plate. The output end of the motor on the left side passes through the mounting plate and is connected to the take-up shaft. A rotating shaft is set at the rear end of the left side of the mounting plate corresponding to the position of the take-up shaft. A plastic roll is wound around the circumference of the rotating shaft. The end of the plastic roll away from the rotating shaft passes through the rear groove and the front groove and is connected to the take-up shaft.

[0007] Preferably, when the motor drives the take-up shaft to rotate, the synchronous drive shaft passively releases the plastic roll. The take-up shaft circumferentially winds up the contaminated plastic roll at the top of the support box. When the contaminated section is completely wound onto the surface of the take-up shaft, the motor stops running. At this time, the clean plastic roll stored on the shaft is pulled to cover the working surface at the top of the support box, forming a self-renewal mechanism for the placement surface based on dual-axis roll-up and unrolling linkage. This achieves the functions of contamination isolation and clean surface switching, solving the problem that common plastic product spraying support fixtures only have a height adjustment function, which can adjust the storage height of plastic products, but lack the function of changing the surface. This cannot guarantee the cleanliness of the plastic product placement surface, and it is easy for paint residue to remain on the placement surface of the fixture after the previous plastic products are sprayed. As a result, subsequent plastic products with different spraying requirements will be contaminated with the paint on the placement surface, affecting the spraying quality.

[0008] Preferably, the bottom of the support frame is provided with three support rods at equal intervals, and the end of the support rod away from the support frame is connected to a special-shaped connecting rod, so that the support frame is stably supported by the three support rods.

[0009] Preferably, a support base plate is provided directly below the irregular connecting rod, and four universal pulleys are provided at the four corners of the bottom of the support base plate, which drive the overall device to move.

[0010] Preferably, a left frame is provided on the left side of the top center of the support base plate, a motor is provided inside the left frame, a left vertical frame is provided on the top of the left frame, and a left drive block is slidably connected inside the left vertical frame. The lead screw drives the left drive block to slide up or down inside the left vertical frame.

[0011] Preferably, the output end of the motor is connected to a lead screw through the left side frame. The top end of the lead screw passes through the left drive block and is rotatably connected to the top end inside the left vertical frame. The left end of the irregular connecting rod is connected to the left drive block, and the motor drives the lead screw to rotate in the forward or reverse direction.

[0012] Preferably, a right frame is provided on the right side of the top middle of the support base plate, corresponding to the position of the left frame. A right vertical frame is provided on the top of the right frame. A sliding rod is provided at the center of the top of the right frame. The left drive block drives the irregular connecting rod to move up and down. The irregular connecting rod drives the right drive block to slide up and down inside the right vertical frame.

[0013] Preferably, a right drive block is slidably connected inside the right vertical frame, and the top of the slider passes through the right drive block and connects to the top of the inside of the right vertical frame. When the right drive block slides up and down, its sliding trajectory is limited by the slider.

[0014] The beneficial effects of this utility model are:

[0015] 1. When the motor drives the take-up shaft to rotate, it synchronously drives the rotating shaft to rotate. During the rotation, the rotating shaft gradually releases the clean plastic roll cloth stored on its surface. At the same time, the area of ​​plastic roll cloth contaminated by the spraying operation on the top of the support box is layered and wound onto the surface of the take-up shaft under the circumferential winding action of the take-up shaft to form a contaminated section for centralized storage. Then the motor stops running. At this time, the clean plastic roll cloth pre-stored on the rotating shaft is covered on the working surface of the top of the support box by the traction force of the take-up shaft under the action of the tension balance system, forming a self-renewal mechanism for the placement surface based on the dual-axis roll-up linkage, realizing the function of contamination isolation and clean surface switching.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a spraying support fixture for plastic products, including a support frame 1; it also includes a support box 2, a rear groove 3, a front groove 4, a mounting plate 5, a motor 6, a take-up shaft 7, a rotating shaft 8, and a plastic roll 9. The support box 2 is disposed inside the support frame 1. The rear side of the top of the support box 2 has a rear groove 3, and the front side of the top of the support box 2 has a front groove 4. The mounting plate 5 is disposed on the right side of the top of the support box 2. The motor 6 is disposed at the front end of the right side of the mounting plate 5. The output end of the motor 6 passes through the mounting plate 5 and is connected to the take-up shaft 7. The rotating shaft 8 is disposed at the rear end of the left side of the mounting plate 5, corresponding to the position of the take-up shaft 7. The plastic roll 9 is wound around the circumference of the rotating shaft 8. The end of the plastic roll 9 away from the rotating shaft 8 passes through the rear groove 3 and the front groove 4 and is connected to the take-up shaft 7. When the take-up shaft 7 is driven to rotate by the motor 6, the rotating shaft is driven synchronously. 8. The plastic roll 9 is passively released. The take-up shaft 7 winds up the contaminated plastic roll 9 at the top of the support box 2 in a circumferential manner. When the contaminated section is completely wrapped around the surface of the take-up shaft 7, the motor 6 stops running. At this time, the clean plastic roll 9 stored in the rotating shaft 8 is pulled to cover the top working surface of the support box 2, forming a self-renewal mechanism for the placement surface based on dual-axis winding and unwinding linkage. This realizes the function of contamination isolation and clean surface switching, which solves the problem that common plastic product spraying support fixtures only have the function of height adjustment, which can adjust the storage height of plastic products, but lack the function of changing the surface. They cannot guarantee the cleanliness of the plastic product placement surface. It is easy for paint residue to remain on the placement surface of the fixture after the previous plastic products are sprayed, which will cause subsequent plastic products with different spraying requirements to be contaminated with the paint on the placement surface, affecting the spraying quality.

[0024] Please see Figures 2-5 In this embodiment, three support rods 10 are evenly spaced at the bottom of the support frame 1. The end of the support rod 10 away from the support frame 1 is connected to a special-shaped connecting rod 11. The support frame 1 is stably supported by the three support rods 10. A support base plate 12 is provided directly below the special-shaped connecting rod 11. Four universal pulleys 22 are provided at the four corners of the bottom of the support base plate 12. The four universal pulleys 22 drive the overall device to move. A left frame 13 is provided on the left side of the top middle of the support base plate 12. A motor 14 is provided inside the left frame 13. A left vertical frame 15 is provided on the top of the left frame 13. A left drive block 16 is slidably connected inside the left vertical frame 15. A lead screw 17 drives the left drive block 16 to slide up or down inside the left vertical frame 15.

[0025] Please see Figures 1-5In this embodiment, the output end of the motor 14 is connected to the lead screw 17 through the left frame 13. The top end of the lead screw 17 is rotatably connected to the top end of the left vertical frame 15 through the left drive block 16. The left end of the irregular connecting rod 11 is connected to the left drive block 16. The motor 14 drives the lead screw 17 to rotate in the forward or reverse direction. A right frame 18 is provided on the right side of the top middle of the support base plate 12, corresponding to the position of the left frame 13. A right vertical frame 19 is provided on the top of the right frame 18. A sliding rod 21 is provided at the center of the top of the right frame 18. The left drive block 16 drives the irregular connecting rod 11 to move up and down. The irregular connecting rod 11 drives the right drive block 20 to slide up and down inside the right vertical frame 19. The right drive block 20 is slidably connected inside the right vertical frame 19. The top end of the sliding rod 21 is connected to the top end of the right vertical frame 19 through the right drive block 20. When the right drive block 20 slides up and down, the sliding trajectory of the right drive block 20 is limited by the sliding rod 21.

[0026] During operation, the plastic product is placed on top of the support box 2, and its height is adjusted according to actual usage. The motor 14 drives the lead screw 17 to rotate forward or backward. The lead screw 17 drives the left drive block 16 to slide up or down inside the left vertical frame 15. The left drive block 16 drives the irregular connecting rod 11 to move up and down. The irregular connecting rod 11 drives the right drive block 20 to slide up and down inside the right vertical frame 19. The sliding trajectory of the right drive block 20 is limited by the slide rod 21 during its up-and-down movement. Simultaneously, the irregular connecting rod 11 drives the support frame 1 to move up and down via the three support rods 10. The support frame 1, through the support box 2, drives the plastic product... After the product moves up and down and the height is adjusted, the plastic product can be sprayed. After the first plastic product is sprayed, when the motor 6 drives the take-up shaft 7 to rotate, the rotating shaft 8 is driven to passively release the plastic roll 9. The take-up shaft 7 rolls up the contaminated plastic roll 9 on the top of the support box 2 by circumferential winding. When the contaminated section is completely wrapped to the surface of the take-up shaft 7, the motor 6 stops running. At this time, the clean plastic roll 9 stored in the rotating shaft 8 is pulled to cover the top working surface of the support box 2. Then the second plastic product is placed on the top of the support box 2 for the next spraying, forming a self-renewal mechanism for the placement surface based on dual-axis roll-up linkage, realizing the function of contamination isolation and clean surface switching.

[0027] Through the above steps, when the motor 6 drives the take-up shaft 7 to rotate, the rotating shaft 8 is simultaneously driven to passively release the plastic roll 9. The take-up shaft 7 winds the contaminated plastic roll 9 at the top of the support box 2 in a circumferential manner. When the contaminated section is completely wrapped around the surface of the take-up shaft 7, the motor 6 stops running. At this time, the clean plastic roll 9 stored in the rotating shaft 8 is pulled to cover the top working surface of the support box 2, forming a self-renewal mechanism for the placement surface based on dual-axis winding and unwinding linkage. This realizes the functions of contamination isolation and clean surface switching, thus solving the problem that common plastic product spraying support fixtures only have the function of height adjustment, which can adjust the storage height of plastic products, but lack the function of changing the surface. This cannot guarantee the cleanliness of the plastic product placement surface, and it is easy for paint residue to remain on the placement surface of the fixture after the previous plastic products are sprayed. As a result, subsequent plastic products with different spraying requirements will be contaminated with the paint on the placement surface, affecting the spraying quality.
