Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating machine technology, specifically a coating machine for plastic products with high flatness. Background Technology
[0002] Plastics are made primarily of natural or synthetic resins, with various additives added, and molded into objects of various shapes under specific temperature and pressure. Plastic products often require coating equipment to coat their surfaces during manufacturing, thereby increasing their aesthetics and durability.
[0003] A coating equipment for plastic products, with application number CN202221875812.7, relates to the field of plastic product processing equipment. It includes a support frame with conveyor rollers inside. Plastic products are placed on the upper surfaces of multiple sets of conveyor rollers. A film roll for coating the plastic products is wound around the outer surface of a hollow cylinder. The beneficial effect of this device is that, during use, rotating the handle drives the bidirectional threaded rod to rotate, thereby causing the threaded plates mounted on its outer surface to move simultaneously towards the center or simultaneously to both sides. This ensures that when the hollow cylinder is installed on the support frame, the center position of the hollow cylinder coincides with the center position of the support frame, reducing the need for multiple positioning of the hollow cylinder caused by the inability of the two sets of positioning plates to move equidistantly at the same time in traditional methods, making the positioning operation more convenient.
[0004] The device has a structure that facilitates the disassembly and unloading of the roll, thereby increasing the convenience of lamination. However, the device lacks a structure to clamp and fix the plastic products during lamination, which makes the plastic products prone to displacement during lamination, thus affecting the lamination effect.
[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing structure of plastic product surface coating machines. Utility Model Content
[0006] The purpose of this invention is to provide a plastic product surface coating machine with high flatness, so as to solve the problem mentioned in the background art that the device does not have a structure to clamp and fix the plastic product during the coating process, and the plastic product is prone to positional displacement during the coating process, thereby affecting the coating effect of the plastic product.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-flatness plastic product surface coating machine, comprising a base, on which a support plate is fixedly installed, and the support plate is symmetrically arranged with two sets of supports about the midpoint of the base; it also includes a slide groove, which is opened on the inner side of the support plate, and a sliding rod is nested inside the slide groove. A placement plate is fixedly installed on the outer side of the sliding rod, and the placement plate is installed on the upper end of the base. A clamping assembly is installed on the upper end of the placement plate, and the workpiece body is clamped by the clamping assembly to fix it and prevent positional displacement during coating.
[0008] Preferably, a servo motor is fixedly installed on the upper end of the base, and a threaded rod is fixedly installed on the output end of the servo motor. An adjustment component is installed on the outside of the threaded rod, and the position of the shelf is adjusted by adjusting the adjustment component.
[0009] Preferably, the clamping assembly includes a slide rail and a first telescopic spring. The slide rail is located inside the shelf, and the first telescopic spring is fixedly installed inside the slide rail. A sliding clamp is fixedly connected to the tail end of the first telescopic spring, and the sliding clamp is nested inside the slide rail. Two sets of sliding clamps are symmetrically arranged about the midpoint of the workpiece body, and the workpiece body is mounted on the upper end of the shelf. This structure allows the sliding clamp to automatically reset due to the elastic force of the first telescopic spring.
[0010] Preferably, the adjusting component includes a threaded connector, which is threadedly connected to the outside of the threaded rod, and a sliding rod is fixedly connected to the outside of the threaded connector; this structure can drive the threaded connector connected to the outside of the threaded rod to move back and forth by rotating the threaded rod.
[0011] Preferably, a concentric shaft is installed on the inner side of the support plate, and a film roller is fixedly installed on the outer side of the concentric shaft, with a film roll wound around the outer side of the film roller; this structure allows the film roll on the outer side of the film roller to be unwound and retracted by rotating the concentric shaft.
[0012] Preferably, a rotating disk is fixedly installed on the outer side of the concentric shaft, and limit holes are opened at equal angles on the inner side of the rotating disk. A fixing plate is fixedly installed on the outer side of the support plate, and a second telescopic spring is fixedly installed on the outer side of the fixing plate. A limit rod is fixedly connected to the tail end of the second telescopic spring, and the limit rod passes through the inner side of the fixing plate. The tail end of the limit rod and the limit hole form a locking structure. This structure can make the limit rod reset by the elastic force of the second telescopic spring.
[0013] Preferably, a flat plate is installed on the inner side of the support plate, and the flat plate is distributed vertically and vertically with the workpiece body; this structure can flatten the upper end of the workpiece body through the flat plate.
[0014] Compared with the prior art, the beneficial effect of this utility model is that the high-flatness plastic product surface coating machine is equipped with:
[0015] 1. The anti-positional displacement structure uses the elastic force of the first telescopic spring to drive the sliding clamp to slide along the inner side of the slide rail, thereby clamping and fixing the two ends of the workpiece body located at the upper end of the placement plate, preventing positional displacement when the workpiece body is coated, which would result in poor coating effect.
[0016] 2. Adjustment structure: The operation of the servo motor drives the threaded rod to rotate. The rotation of the threaded rod will drive the threaded connector on the outer threaded connection to move left and right. In turn, the left and right movement of the threaded connector will drive the workpiece body on the upper part of the shelf to adjust its position.
[0017] 3. The structure facilitates film application. By attaching the beginning of the film roll wound on the outside of the film roller to the outside of the workpiece body, the movement of the workpiece body drives the film roller to rotate. The rotation of the film roller will automatically attach the outer film roll to the outside of the workpiece body, thereby achieving the effect of automatic film application.
[0018] 4. Engaging structure: When film coating is not required, the limit rod is automatically reset by the elastic force of the second telescopic spring and engages with the corresponding limit hole, thereby fixing the rotating disk by the engagement of the tail end of the limit rod with the limit hole.
[0019] 5. Leveling structure: When the placement plate moves back and forth with the workpiece body, the flat plate on the inner side of the support plate will squeeze the film adhering to the upper end of the workpiece body, squeeze out the air bubbles contained inside, improve its flatness, and the squeezing by the flat plate can make the film adhere more tightly to the outer surface of the workpiece body.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0028] This utility model provides the following technical solution:
[0029] Example 1: As Figures 1-5 The technical solution shown is as follows: A plastic product surface coating machine with high flatness is disclosed, comprising: a base 1, on which a support plate 2 is fixedly installed, and the support plate 2 is symmetrically arranged with two sets of support plates about the midpoint of the base 1; it also includes a slide groove 3, which is opened on the inner side of the support plate 2, and a sliding rod 4 is nested inside the slide groove 3. A placement plate 5 is fixedly installed on the outer side of the sliding rod 4, and the placement plate 5 is installed on the upper end of the base 1. A clamping assembly is installed on the upper end of the placement plate 5. The workpiece body 9 is clamped by the clamping assembly to fix it and prevent position displacement during coating.
[0030] The clamping assembly includes a slide rail 6 and a first telescopic spring 7. The slide rail 6 is opened inside the shelf 5, and the first telescopic spring 7 is fixedly installed inside the slide rail 6. The tail end of the first telescopic spring 7 is fixedly connected to a sliding clamp 8, and the sliding clamp 8 is nested inside the slide rail 6. Two sets of sliding clamps 8 are arranged symmetrically about the midpoint of the workpiece body 9, and the workpiece body 9 is installed on the upper end of the shelf 5.
[0031] When this structure needs to coat the workpiece body 9, firstly, pull the sliding clamps 8 at both ends to compress the first telescopic spring 7 and slide along the inner side of the slide rail 6. Then, place the workpiece body 9 on the upper end of the placement plate 5, release the sliding clamps 8, and the sliding clamps 8 will reset by the elastic force of the first telescopic spring 7, so that the sliding clamps 8 at both ends will reset themselves and move towards each other along the inner side of the slide rail 6 to clamp the two ends of the workpiece body 9, thereby fixing the workpiece body 9 on the upper end of the placement plate 5 and preventing it from shifting in the position where the coating is applied, which would affect the coating effect. Example
[0032] Unlike Embodiment 1, an adjustment structure is added simultaneously when clamping the workpiece body 9, such as... Figures 1-3 , Figure 6 The technical solution shown in the invention provides a high-flatness plastic product surface coating machine, which discloses: a servo motor 10 is fixedly installed on the upper end of the base 1, and a threaded rod 11 is fixedly installed on the output end of the servo motor 10. An adjustment component is installed on the outside of the threaded rod 11, and the position of the shelf 5 is adjusted by adjusting the adjustment component; the adjustment component includes a threaded connector 12, which is threadedly connected to the outside of the threaded rod 11, and a sliding rod 4 is fixedly connected to the outside of the threaded connector 12; a support plate 2 is installed on the inner side. A concentric shaft 14 is provided, and a film roller 15 is fixedly installed on the outside of the concentric shaft 14, and a film roll 16 is wound on the outside of the film roller 15; a rotating disk 17 is fixedly installed on the outside of the concentric shaft 14, and limit holes 18 are opened at equal angles on the inner side of the rotating disk 17; a fixed plate 19 is fixedly installed on the outside of the support plate 2, and a second telescopic spring 20 is fixedly installed on the outside of the fixed plate 19; a limit rod 21 is fixedly connected to the tail end of the second telescopic spring 20, and the limit rod 21 passes through the inner side of the fixed plate 19, and the tail end of the limit rod 21 and the limit hole 18 form a locking structure;
[0033] After the workpiece body 9 is fixed, the limiting rod 21 is pulled, causing the tail end of the limiting rod 21 to separate from the inner side of the limiting hole 18. After separation, the rotating disk 17 is in an active state. Then, the first end of the film roll 16 is adhered to the front end of the workpiece body 9. After adhesion, the servo motor 10 is run. The output end of the servo motor 10 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 causes the threaded connector 12 with the outer threaded connection to move back and forth, thereby causing the sliding rod 4 to slide along the inner side of the slide groove 3. The sliding of the sliding rod 4 will cause the placement plate 5 to move forward, thereby causing the workpiece body 9 to move as well. Subsequently, the movement of the workpiece body 9 will cause the adhered film roll 16 to move along with it, thereby causing the film roll 16 to cover the upper surface of the workpiece body 9. After the film covering is completed, the limiting rod 21 is released. The limiting rod 21 is reset by the elastic force of the second telescopic spring 20, thereby causing the tail end of the limiting rod 21 to engage with the corresponding limiting hole 18, thereby fixing the rotating disk 17 and preventing the film roller 15 from rotating.
[0034] Example 3: Unlike Example 2, a leveling structure was added simultaneously when adjusting the position of the workpiece body 9, such as... Figure 5 The present invention provides a technical solution: a plastic product surface coating machine with high flatness, which discloses that: a flat plate 13 is installed on the inner side of the support plate 2, and the flat plate 13 and the workpiece body 9 are distributed vertically in correspondence.
[0035] When the workpiece body 9 moves back and forth, the structure causes the adhered film roll 16 to cover the upper end of the workpiece body 9. When the workpiece body 9 moves to the lower end of the flat plate 13, the flat plate 13 will squeeze the film roll 16 at the lower end, thereby squeezing out the air bubbles between the film roll 16 and the workpiece body 9, improving the flatness of the surface of the workpiece body 9. Furthermore, the squeezing by the flat plate 13 can make the film roll 16 adhere more tightly to the outside of the workpiece body 9.
[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] 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.
