Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for plastic product spraying processing. Background Technology

[0002] Plastic products are a general term for daily necessities and industrial products made primarily from plastics. They include all products manufactured using processes such as injection molding and thermoforming. Plastics, along with synthetic rubber and synthetic fibers, form the three major synthetic materials indispensable to daily life.

[0003] In the production of plastic products, painting is often required. Before painting, the products need to be clamped and fixed. Most existing clamping methods use cylinders or lead screws to drive sliders, thereby moving the clamps to hold and fix the plastic products. However, when the plastic products are soft, this clamping method makes it difficult to control the clamping force and the distance between the clamps, making the processed parts easily deformed and unstable. For example, with soft mobile phone shells, this can even lead to uneven painting. Moreover, the clamps may block some parts of the exterior, making it impossible to paint those areas and requiring secondary paint touch-ups, thus affecting the painting effect.

[0004] Therefore, this utility model provides a clamping device for spray coating of plastic products to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] This utility model provides a clamping device for spray coating processing of plastic products, such as... Figures 1-5 As shown, the system includes a collection box 1. Excess paint during spraying will fall into the collection box 1 to prevent it from falling to the ground. A fixing plate 2 is fixedly connected inside the collection box 1. The fixing plate 2 is provided with a clamping structure 3. The clamping structure 3 includes an auxiliary component 4. The auxiliary component 4 is provided with multiple mounting components 5, which are evenly arranged. The mounting component 5 is provided with a first clamping component 6 or a second clamping component 7. The mounting component 5 includes a fixing cylinder 51, and an extension rod 52 is slidably connected inside the fixing cylinder 51.

[0017] The auxiliary component 4 includes a protective box 41 fixedly connected to the fixed plate 2. A motor 42 is fixedly connected inside the protective box 41. The motor 42 is existing technology and will not be described in detail here. In order to simplify the technical solution, some devices such as control switches, encoders, connecting wires, and power supplies are not illustrated or described. However, those skilled in the art know or should know that such devices need to be arranged in a suitable position to ensure the implementation effect. A rotating shaft 43 is rotatably connected to the fixed plate 2. The bottom of the rotating shaft 43 passes through the fixed plate 2 and is fixedly connected to the output end of the motor 42. Multiple connecting plates 44 are fixedly connected to the rotating shaft 43. The multiple connecting plates 44 are arranged at equal angles. Multiple arc-shaped plates 45 are fixedly connected between each pair of the multiple connecting plates 44. The multiple arc-shaped plates 45 are arranged at equal intervals. The arc-shaped plates 45 at the same level can form a circle.

[0018] The fixed cylinder 51 has a through-hole 511 on one side. The fixed cylinder 51 is fixedly connected to the connecting plate 44 or the arc plate 45. Two racks 512 are fixedly connected to one side of the fixed cylinder 51, and the two racks 512 are symmetrically arranged. The through-hole 511 is located between the two racks 512. A scale 513 is provided on the side of the rack 512.

[0019] The top of the extension rod 52 is fixedly connected to a top block 521. The top block 521 is provided with a cross groove 522. A fixing post 523 is fixedly connected to the middle position of the cross groove 522. A cap 53 is fitted on the top of the fixing post 523. The extension rod 52 is provided with a sliding groove 524. A sliding rod 54 is slidably connected in the sliding groove 524.

[0020] One end of the slide rod 54 passes through the through-hole 511 and extends out a portion. A gear 541 is fixedly connected to one end of the slide rod 54. The gear 541 corresponds to and meshes with the rack 512.

[0021] The first clamping component 6 consists of a horizontal plate 8 and two Z-shaped elastic pieces 9. The second clamping component 7 consists of a horizontal plate 8 and a Z-shaped elastic piece 9. The Z-shaped elastic piece 9 is fixedly connected to one end of the horizontal plate 8. The horizontal plate 8 is provided with a positioning hole 81, and the positioning hole 81 corresponds to the fixing post 523.

[0022] Specifically, before use, select the appropriate clamping component 6 or clamping component 7 according to the size of the plastic product. The size of clamping component 7 can also be arbitrarily selected. When the size of the plastic product is smaller than the distance between the two mounting components 5, clamping component 6 of the appropriate size can be selected according to the size of the product. In this case, place the horizontal plate 8 on clamping component 6 into the cross groove 522 and insert the fixing post 523 into the positioning hole 81. When the length and width of the processed parts are different and the difference is large, clamping component 6 of different sizes can be selected or simply one clamping component 6 can be selected for installation. When installing one, the bracket will put the cap 53 on the top of the fixing post 523. When two need to be installed, put another clamping component 6 into the cross groove 522, making it perpendicular to the previous clamping component 6, and put the cap 53 on it. When the length and width of the processed parts are different and the difference is small, or when the cross section of the processed parts is circular, such as a cup, two clamping components 6 of the same size can be installed directly.

[0023] When a certain dimension of the workpiece to be processed is greater than the distance between the two mounting parts 5, the mounting part 5 at the corresponding position can be selected and the second clamping part 7 can be installed. The installation method is the same as the first clamping part 6. When installing the workpiece, first squeeze the Z-shaped elastic disc 9 towards the middle to deform it. At this time, the farthest end is located inside the workpiece. Then, place the workpiece on the Z-shaped elastic disc 9, and then release the Z-shaped elastic disc 9. The Z-shaped elastic disc 9 will return to its original shape under its own elastic force. During this process, one end of the Z-shaped elastic disc 9 will abut against one side of the workpiece, thereby fixing the workpiece.

[0024] Furthermore, there may be height differences in the clamping areas inside the shell-shaped workpiece. In this case, it is necessary to adjust the height of the clamping components. Pull the slide bar 54 outward to separate the gear 541 from the rack 512. Then pull the extension rod 52 upward to adjust the height of the top block 521. The adjusted height can be determined according to the scale 513. After the height is determined, push the slide bar 54 back and rotate the slide bar 54 to match the gear 541 with the rack 512 until the gear 512 is locked in the rack 541, thus completing the height adjustment.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
