Description

Technical Field

[0001] This utility model relates to the technical field of processing equipment for daily-use plastic products, and in particular to a device for micro-textured embossing on the surface of plastic products. Background Technology

[0002] Microtexturing of plastic products is a process that creates fine textures on the surface of plastic products. It aims to enhance the appearance, texture and functionality of plastic products. It mainly uses micro-nano level pressure and a mold with a specific texture to imprint fine patterns or textures onto the surface of plastic products, forming anti-slip textures or decorative textures.

[0003] Chinese Patent Publication No. CN220720267U discloses an embossing device for plastic processing, including an embossing machine body, a support base, a push cylinder, and an embossing mold. The push cylinder is located at the upper end of the embossing machine body, and the embossing mold is located at the lower end of the push cylinder. A fixing component is used to fix the plastic product on the worktable, and a limiting component is used to limit the pressure rods. This device, by setting a fixing component at the upper end of the embossing machine body and a limiting component at the front end of the fixing component to restrict it, and by setting two sets of pressure rods, can fix and compress the plastic product, avoiding the situation where the plastic product sticks to the embossing mold during embossing and the plastic product rises when the push cylinder drives the embossing mold upwards. This makes the embossing operation of plastic products more convenient and smooth, improves the embossing efficiency, and makes the device more practical.

[0004] Although the equipment described in the above literature can fix plastic products before imprinting, it is only suitable for plate-shaped objects, resulting in poor applicability and flexibility of the equipment. At the same time, uneven imprinting may occur during the pressing process, resulting in poor imprinting quality. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, a micro-texture embossing device for the surface of plastic products includes an operating table 1. A fixing component 2 is fixedly connected to the upper middle part of the operating table 1. Slide rods 3 are fixedly connected to the four corners of the upper part of the operating table 1. A top plate 4 is fixedly connected to the upper end of the four slide rods 3. An electric cylinder 5 is fixedly connected to the upper middle part of the top plate 4. A push plate 6 is fixedly connected to the output end of the electric cylinder 5 through the top plate 4. A plurality of buffer components 7 arranged in a rectangular array are fixedly connected to the lower middle part of the push plate 6. An embossing component 8 is fixedly connected to the lower end of the plurality of buffer components 7.

[0026] Specifically, the push plate 6 and the imprinting assembly 8 are both slidably connected to the four slide rods 3.

[0027] like Figure 3 As shown, the fixed assembly 2 includes two slide rails 21 fixedly connected to both sides of the upper end of the operating table 1. Two clamping plates 22 are slidably connected to the upper sides of the two slide rails 21. A rotating plate 23 is rotatably connected to the middle of the upper end of the operating table 1. A connecting rod 24 is rotatably connected to both sides of the upper end of the rotating plate 23. The two connecting rods 24 are fixedly connected to a clamping plate 22 that is close to each other. An electric push rod 25 is fixedly connected to one side of the upper end of the operating table 1. The output end of the electric push rod 25 is rotatably connected to the rotating plate 23. A support 26 is fixedly connected to the middle of the two slide rails 21 that are close to each other.

[0028] Furthermore, guide rods 27 are fixedly connected to both sides of the upper end of the operating table 1. The two guide rods 27 are slidably connected to the two clamping plates 22. Springs 28 are fixedly connected to both sides of the two clamping plates 22 that are close to each other. The two springs 28 are sleeved on the outer surface of the guide rod 27 that is close to each other.

[0029] Spring 28 can act as a buffer during the clamping of plastic products by clamping plates 22. At the same time, rubber layers are fixedly connected to the ends of the two clamping plates 22 that are close to each other, which can increase the friction between the clamping plates 22 and the plastic products, play an anti-slip role, and also protect the outer surface of the plastic products.

[0030] In this embodiment, the plastic product to be pressed is placed on the upper side of the two supports 26. The electric push rod 25 pushes the rotating plate 23 to rotate. The output end of the electric push rod 25 moves to the left, thereby pulling the rotating plate 23 connected to it to rotate counterclockwise. After the rotating plate 23 rotates, it pushes the two connecting rods 24 to move towards the plastic product, thereby driving the two clamping plates 22 to move towards the plastic product until the plastic product is clamped and fixed.

[0031] Example 2

[0032] Based on Example 1, this embodiment adds a buffer component 7 and an imprinting component 8, which can achieve uniform imprinting of plastic products, reduce shock and buffer during the imprinting process, and allow for quick replacement of the imprinting mold, thereby improving production efficiency.

[0033] like Figure 4As shown, the buffer assembly 7 includes a housing 71 fixedly connected to the lower end of the push plate 6. A pressure block 72 is slidably connected to the lower side of the inner surface of the housing 71. Slide grooves 73 are provided on both sides of the pressure block 72. A damper 74 is fixedly connected to the bottom wall of each of the two slide grooves 73. A pressure rod 75 is fixedly connected to both sides of the top wall of the inner surface of the pressure block 72. Two springs 76 are fixedly connected to the top wall of the inner surface of the housing 71 and the upper end of the pressure block 72. The two springs 76 are sleeved on the outer surface of a pressure rod 75 that is close to each other.

[0034] Specifically, both pressure rods 75 are slidably connected to a sliding groove 73 that is close to each other.

[0035] like Figure 5 As shown, the embossing assembly 8 includes a plate 81 fixedly connected to the lower end of several pressing blocks 72. A heating plate 82 is fixedly connected to the lower end of the plate 81. Slide rails 83 are fixedly connected to both sides of the lower end of the heating plate 82. A template 84 is slidably connected to the middle of the two slide rails 83.

[0036] Among them, heating plate 82 is a mature existing technology, and commonly used ones include electric heating plate, heat conduction heating plate, composite heating plate, etc.

[0037] Heating the template 84 allows the plastic material to reach its viscous flow temperature, reducing its viscosity, enhancing its fluidity, and ensuring that the microstructure can be completely imprinted. For thermoplastics such as ABS, PC, and PMMA, heating to 150-250℃ is typically required to achieve a good imprinting effect.

[0038] In this embodiment, the electric cylinder 5 pushes the push plate 6 downward, and the push plate 6 pushes the buffer assembly 7 and the imprinting assembly 8 downward. When the template 84 comes into contact with the plastic product, the pressure block 72 stops moving downward, and the housing 71 pushes the pressure rod 75 to squeeze the damper 74. At the same time, the housing 71 squeezes the second spring 76. The second spring 76 and the damper 74 work together to reduce shock and buffer. Meanwhile, the heating plate 82 heats the template 84, and the template 84 imprints micro-textures on the surface of the plastic product.

[0039] When it is necessary to replace the template 84, pull the template 84 out of the slide rail 2 83, put the new template 84 into the slide rail 2 83, and push the template 84 to make it correspond to the position of the heating plate 82.

[0040] It should be noted that the specific installation method, circuit connection method, and control method of the electric push rod 25, electric cylinder 5, and heating plate 82 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0041] The working principle of this utility model is as follows: First, the plastic product to be pressed is placed on the upper side of the two supports 26. The rotating plate 23 is pushed to rotate by the electric push rod 25. The rotating plate 23 drives the connecting rod 24 to move. The connecting rod 24 pulls the two clamping plates 22 to move towards the plastic product until the plastic product is clamped and fixed.

[0042] Then, the electric cylinder 5 pushes the push plate 6 to move down, and the push plate 6 pushes the buffer assembly 7 and the imprinting assembly 8 to move down. When the template 84 comes into contact with the plastic product, the pressure block 72 stops moving down, and the housing 71 pushes the pressure rod 75 to squeeze the damper 74. At the same time, the housing 71 squeezes the second spring 76. The second spring 76 and the damper 74 work together to reduce shock and buffer. At the same time, the heating plate 82 heats the template 84, and the template 84 imprints micro-textures on the surface of the plastic product.

[0043] In this embodiment, the embossing component 8 can emboss the surface of plastic products with relatively regular shapes, such as plastic basins and plastic chairs. These products need to be kept flat during the embossing process to ensure the integrity and accuracy of the embossed pattern.

[0044] For some plastic products with complex shapes, such as plastic shells and containers, template 84 can be customized according to their shape to ensure that the embossed pattern can accurately cover the surface of the product.

[0045] When it is necessary to replace the template 84, pull the template 84 out of the slide rail 2 83, put the new template 84 into the slide rail 2 83, and push the template 84 to make it correspond to the position of the heating plate 82.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
