Description
Technical Field
[0001] This utility model relates to the field of plastic parts technology, and in particular to a clamping device for spraying plastic parts. Background Technology
[0002] Plastic parts are a general term for daily and industrial products made primarily of plastic. They include all crafts made from plastic, such as injection molding and vacuum forming. Currently, plastic items are generally coated with paint to prevent oxidation.
[0003] Existing clamping devices for plastic parts spraying typically hold the plastic parts on the clamping device for individual spraying operations. However, this is cumbersome when processing and spraying multiple plastic parts, requiring repeated placement and removal operations, which is inconvenient. Furthermore, after spraying, the plastic parts need to be manually removed and placed in the receiving box, resulting in low overall work efficiency.
[0004] Therefore, addressing the issues of existing plastic part spraying clamping devices being unable to simultaneously spray multiple plastic parts and lacking automatic unloading and collection devices, resulting in low overall work efficiency, this invention utilizes a drive motor to rotate a gear ring, thereby enabling the mounting base to rotate with the connecting column. This allows the plastic part to be mounted in two clamping blocks, achieving clamping and allowing the next plastic part to be sprayed immediately after the previous one is finished, thus improving work efficiency. Simultaneously, a servo motor drives a pusher block to push the clamped and sprayed plastic part into the storage bin, achieving automatic unloading. Utility Model Content

This causes the mounting base to rotate synchronously with the connecting column. At the same time, the plastic part can be installed in two clamping blocks, which move backward along the slide groove. Under the action of the spring, the clamping blocks are forcefully clamped to hold the plastic part. This allows the spraying device to spray the next plastic part immediately after spraying one part, improving the working efficiency of the device.

After the plastic parts are coated, the servo motor drives the first threaded rod to rotate, causing the first threaded block, which is threadedly connected to the first threaded rod, to move along the thread direction. This allows the connecting block to slide along the connecting groove direction, thereby driving the push block to move synchronously, pushing the coated plastic parts away from the two clamping blocks and causing the plastic parts to fall into the storage box. During subsequent processing of the plastic parts, the rocker arm can be rotated to move the second threaded block along the direction of the second threaded rod, and the slider can slide along the slide rail direction, allowing the storage box to move with the second threaded block for easy retrieval by personnel.

[0028] Please see Figure 2 and Figure 4 A fixed post 9 is fixedly installed on the right side of the upper end of the base 1. A fixed seat 10 is fixedly installed on the upper end of the fixed post 9. A servo motor 101 is fixedly installed on the right side of the inner side of the fixed seat 10.

A push block 112 is fixedly installed on the other end of the connecting block 111. Under the action of the servo motor 101, the first threaded rod 102 drives the first threaded block 103, which is threadedly connected to the first threaded rod 102, to move along the thread direction, so that the connecting block 111 can slide along the direction of the connecting groove 11, thereby driving the push block 112 to move synchronously to complete the unloading process of the plastic part.
[0029] Please see Figure 1 and Figure 3A first baffle 12 is fixedly installed on the upper end of the base 1 to the left of the fixed column 9. Slide rails 121 are fixedly installed on the left and right sides of the rear end of the first baffle 12. A second baffle 13 is fixedly installed on the end of the slide rail 121 away from the first baffle 12. A slider 14 is slidably connected to the surface of the slide rail 121. The lower end of the slide rail 121 is fixedly connected to the base 1, and the lower end of the second baffle 13 is fixedly connected to the base 1. By installing the slide rail 121, the slider 14 can slide along the direction of the slide rail 121, which increases the convenience of picking up plastic parts later.
[0030] Please see Figure 2 and Figure 3 The rear end of the first baffle 12 is rotatably connected to the second threaded rod 122, which is located between the two slide rails 121. The end of the second threaded rod 122 away from the first baffle 12 extends to the rear side of the second baffle 13. A rocker arm 123 is fixedly installed at the rear end of the second threaded rod 122. A second threaded block 15 is threadedly connected to the surface of the second threaded rod 122. The second threaded block 15 and the slider 14 are fixedly connected. A storage box 16 is fixedly installed at the upper end of the second threaded block 15. By rotating the rocker arm 123, the second threaded rod 122 rotates and drives the second threaded block 15, which is threadedly connected to the second threaded rod 122, to move along the thread direction. Simultaneously, the slider 14 moves, so that the storage box 16 can move with the slider 14, thereby facilitating the handling of plastic parts and increasing convenience.
[0031] Working principle: According to Figure 1 , Figure 2 , Figure 5 and Figure 6 Before operation, the plastic part is installed in the two clamping blocks 83, so that the two clamping blocks 83 are pressed back. Under the action of the spring 86, the clamping blocks 83 are pressed against the plastic part to achieve the clamping operation of the plastic part. At the same time, the drive motor 21 works, so that the transmission rod 22 drives the gear 23 to rotate, so that the gear ring 31 connected to the gear 23 rotates accordingly, so as to control the mounting base 4 to rotate with the connecting column 3. This allows the spray head 7 to spray the next plastic part immediately after spraying the previous one, achieving the purpose of continuous spraying and increasing the working efficiency of the device.
[0032] according to Figures 1-4After the plastic parts are coated, the servo motor 101 drives the first threaded rod 102 to rotate, which causes the first threaded block 103, which is threadedly connected to the first threaded rod 102, to drive the connecting block 111 to slide along the connecting groove 11. This controls the push block 112 to move with the connecting block 111, thereby pushing the coated plastic parts out of the two clamping blocks 83 and into the storage box 16, thus realizing the automatic unloading operation of the plastic parts. When personnel need to retrieve the plastic parts, the rocker arm 123 is turned, causing the second threaded rod 122 to rotate. This causes the second threaded block 15, which is threadedly connected to the second threaded rod 122, to drive the slider 14 to slide along the slide rail 121, thereby controlling the storage box 16 to move with the second threaded block 15, making it easier for personnel to retrieve the parts and increasing convenience.
[0033] In this device, the drive motor 21 and the servo motor 101 are connected to an external power source via a power cord and then started. The drive motor 21 and the servo motor 101 are known and existing technologies on the market and will not be described in detail here.
[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
