Description

Technical Field

[0001] This utility model relates to the field of plastic sheet processing technology, specifically to a device for rapid embossing of surface textures on plastic products. Background Technology

[0002] In modern industry and decoration, plastic sheets have become a widely used basic material due to their lightweight, corrosion resistance, and ease of processing. To give the sheets diverse decorative effects such as wood grain, stone grain, and leather grain, hot-pressing with hot rollers creates three-dimensional textures on the surface, effectively enhancing visual appeal and tactile experience.

[0003] A search revealed that patent application number 202323005898.5 discloses a hot-pressing device for surface texture of plastic sheets, belonging to the field of plastic sheet processing. This utility model includes a conveyor frame for conveying the plastic sheets. One side of the conveyor frame is equipped with an anti-deviation mechanism to prevent the plastic sheets from shifting during conveying. The other side of the conveyor frame is equipped with a work box. One side of the work box contains a hot-pressing mechanism for processing the surface texture of the plastic sheets, and the other side of the work box contains a cooling mechanism for cooling the hot-pressed plastic sheets.

[0004] Although the hot pressing mechanism of this plastic sheet surface texture hot pressing device cleans the surface of the plastic sheet with a dust suction roller and then hot presses the texture onto the surface of the sheet with a hot pressing roller, the device is not easy to adjust the height of the hot pressing roller, making it difficult to adapt to the embossing requirements of plastic sheets of different thicknesses. When the sheet thickness changes, if the height of the hot pressing roller cannot be adjusted in time, it may lead to insufficient embossing depth, uneven pressure, or even problems such as sheet breakage and equipment jamming.

[0005] Therefore, we propose a rapid embossing device for the surface texture of plastic products. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rapid embossing device for surface textures of plastic products, which solves the problem that existing devices are not convenient for adjusting the height of the hot press roller, resulting in their inability to adapt to plastic sheets of different thicknesses and thus having limitations.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a rapid embossing device for surface texture of plastic products, comprising a first U-shaped plate, wherein a conveying component is disposed inside the first U-shaped plate;

[0008] A position adjustment component is symmetrically arranged on the front and rear sides of the top of the first U-shaped plate, and a hot pressing component is arranged in the middle of the top surface of the first U-shaped plate.

[0009] The hot pressing assembly includes a second U-shaped plate fixedly installed in the middle of the top surface of the first U-shaped plate, a second hydraulic rod fixedly installed in the middle of the top surface of the second U-shaped plate, a third U-shaped plate fixedly installed through the output end of the second hydraulic rod through the top surface of the second U-shaped plate, and a hot pressing roller rotatably installed on the bottom end of the inner wall of the third U-shaped plate via a bearing ring.

[0010] Preferably, a motor is fixedly installed on the rear side wall of the bottom end of the third U-shaped plate. The output end of the motor passes through the side wall of the third U-shaped plate and is fixedly installed on the middle of the end face of the hot press roller on the same side. The motor can drive the hot press roller to rotate, thereby performing hot pressing on the plastic plate passing under the hot press roller. The rotation speed of the hot press roller is the same as the conveying speed of the conveying component.

[0011] Preferably, a second limiting rod is fixedly installed on both the front and rear sides of the top surface of the third U-shaped plate. The second limiting rod is slidably fitted on the top surface of the second U-shaped plate. The second limiting rod can limit the up and down movement of the third U-shaped plate to prevent the position of the third U-shaped plate from shifting during movement.

[0012] Preferably, a circular groove is provided at the center of the top end of the second limiting rod, a clearance groove communicating with the circular groove is provided on the side wall of the second limiting rod, and a clearance hole communicating with the circular groove is provided at the center of the top surface of the second limiting rod.

[0013] Preferably, a threaded rod is rotatably mounted on the bottom surface of the circular groove via a bearing ring. The top end of the threaded rod passes through a relief hole and extends above the second limiting rod. The top end of the threaded rod is rotatably mounted inside the relief hole via a bearing ring. A knob is fixedly mounted on the top surface of the threaded rod, which facilitates the rotation of the threaded rod.

[0014] Preferably, the outer surface of the threaded rod is threaded with a threaded slider that is slidably fitted inside a circular groove. A limiting plate that is slidably fitted inside a relief groove is fixedly installed on the side wall of the threaded slider. When the threaded rod rotates, it can drive the threaded slider and the limiting plate to move, and the positions of the threaded slider and the limiting plate can be adjusted. When the second limiting rod moves up and down, the limiting plate contacts the top surface of the second U-shaped plate, which can limit the second limiting rod, and then limit the third U-shaped plate and the hot press roller, so as to prevent the hot press roller from deviating in the downward movement distance.

[0015] Preferably, the position adjustment assembly includes a first hydraulic rod, an adjustment plate, and a first limiting rod. The first hydraulic rod is fixedly installed at the top of the front and rear side walls of the first U-shaped plate. The output end of the first hydraulic rod passes through the side wall of the first U-shaped plate and is fixedly installed with the adjustment plate. The adjustment plate can be moved by the first hydraulic rod, thereby adjusting the position of the plastic plate conveyed on the conveying assembly so that the plastic plate is aligned with the hot press roller.

[0016] Preferably, a first limiting rod is fixedly installed at both ends of the adjusting plate. The first limiting rod slides onto the side wall of the first U-shaped plate on the same side as the adjusting plate. The left end of the adjusting plate is arc-shaped. The first limiting rod can limit the two ends of the adjusting plate, thereby increasing the stability of the adjusting plate when it moves.

[0017] This invention provides a device for rapid embossing of surface textures on plastic products. It has the following advantages:

[0018] 1. This rapid embossing device for plastic product surface texture uses a second hydraulic rod to push a third U-shaped plate and a hot press roller downwards, causing the hot press roller to contact the top surface of the plastic sheet. Then, a motor drives the hot press roller to rotate, thus hot-pressing patterns onto the top surface of the plastic sheet. This achieves the purpose of easily adjusting the height of the hot press roller to adapt to plastic sheets of different thicknesses, and has a wide range of applications. It solves the problem that existing devices are not easy to adjust the height of the hot press roller, which makes them unable to adapt to plastic sheets of different thicknesses and has limitations.

[0019] 2. The rapid embossing device for surface texture of plastic products limits the movement of the third U-shaped plate by the second limiting rod, which can increase the stability of the third U-shaped plate during movement. By rotating the threaded rod with a knob, the distance between the bottom surface of the limiting plate and the bottom surface of the second limiting rod can be the same as the downward movement distance of the third U-shaped plate and the hot press roller. By the contact between the limiting plate and the top surface of the second U-shaped plate, the movement of the second limiting rod can be restricted, thereby avoiding deviations in the downward movement distance of the third U-shaped plate and the hot press roller, and improving the accuracy of adjusting the position of the third U-shaped plate and the hot press roller.

[0020] 3. The rapid embossing device for the surface texture of plastic products conveys the plastic sheet to the right through the conveying assembly. During this process, the first hydraulic rod is activated to push the adjusting plate to move. Then, the adjusting plate pushes the plastic sheet to the center of the conveying assembly, so that the plastic sheet is aligned with the hot press roller. Attached Figure Description

[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] Example 1:

[0029] like Figure 1-5 As shown: The system includes a first U-shaped plate 1, with a conveying assembly 2 inside. Position adjustment assemblies 3 are symmetrically arranged on the front and rear sides of the top of the first U-shaped plate 1. A hot-pressing assembly 4 is located in the center of the top surface of the first U-shaped plate 1. The hot-pressing assembly 4 includes a second U-shaped plate 41 fixedly installed in the center of the top surface of the first U-shaped plate 1. A second hydraulic rod 42 is fixedly installed in the center of the top surface of the second U-shaped plate 41. A third U-shaped plate 43 is fixedly installed through the top surface of the second U-shaped plate 41 at the output end of the second hydraulic rod 42. The bottom end of the inner wall of the third U-shaped plate 43 is rotatably mounted via a bearing ring. A hot press roller 44 is provided. A motor 45 is fixedly installed on the rear side wall of the bottom end of the third U-shaped plate 43. The output end of the motor 45 passes through the side wall of the third U-shaped plate 43 and is fixedly installed on the middle of the end face of the hot press roller 44 on the same side. The third U-shaped plate 43 and the hot press roller 44 are pushed downward by the second hydraulic rod 42, so that the hot press roller 44 contacts the top surface of the plastic plate. Then, the motor 45 drives the hot press roller 44 to rotate, so that textures can be hot-pressed on the top surface of the plastic plate. This achieves the purpose of easily adjusting the height of the hot press roller 44, so as to adapt to plastic plates of different thicknesses and has a wide range of applications.

[0030] Example 2:

[0031] like Figure 1-5As shown: Second limiting rods 46 are fixedly installed on both the front and rear sides of the top surface of the third U-shaped plate 43. The second limiting rods 46 are slidably fitted onto the top surface of the second U-shaped plate 41. A circular groove 461 is formed in the middle of the top of the second limiting rod 46. A clearance groove 462 communicating with the circular groove 461 is formed on the side wall of the second limiting rod 46. A clearance hole 463 communicating with the circular groove 461 is formed in the middle of the top surface of the second limiting rod 46. A threaded rod 47 is rotatably installed on the bottom surface of the circular groove 461 via a bearing ring. The top of the threaded rod 47 passes through the clearance hole 463 and extends above the second limiting rod 46. The top of the threaded rod 47 is rotatably installed inside the clearance hole 463 via a bearing ring. A knob 410 is fixedly installed on the top surface of the threaded rod 47. A threaded sleeve is fitted on the outer surface of the threaded rod 47. A threaded slider 48 is slidably fitted inside a circular groove 461. A limiting plate 49, which is slidably fitted inside a relief groove 462, is fixedly installed on the side wall of the threaded slider 48. The movement of the third U-shaped plate 43 is limited by the second limiting rod 46, which can increase the stability of the third U-shaped plate 43 when it moves. By rotating the threaded rod 47 driven by the knob 410, the distance between the bottom surface of the limiting plate 49 and the bottom surface of the second limiting rod 46 can be the same as the downward movement distance of the third U-shaped plate 43 and the hot pressure roller 44. By the contact between the limiting plate 49 and the top surface of the second U-shaped plate 41, the movement of the second limiting rod 46 can be limited, thereby avoiding deviation in the downward movement distance of the third U-shaped plate 43 and the hot pressure roller 44, and improving the accuracy of adjusting the position of the third U-shaped plate 43 and the hot pressure roller 44.

[0032] Example 3:

[0033] like Figure 1-2 As shown: The position adjustment assembly 3 includes a first hydraulic rod 31, an adjustment plate 32, and a first limiting rod 33. The first hydraulic rod 31 is fixedly installed on the top of the front and rear side walls of the first U-shaped plate 1. The output end of the first hydraulic rod 31 passes through the side wall of the first U-shaped plate 1 and is fixedly installed on the adjustment plate 32. The first limiting rod 33 is fixedly installed on both ends of the adjustment plate 32. The first limiting rod 33 slides onto the side wall of the first U-shaped plate 1 on the same side as it. The left end of the adjustment plate 32 is arc-shaped. The plastic plate is conveyed to the right by the conveying assembly 2. During this process, the first hydraulic rod 31 is activated to push the adjustment plate 32 to move. Then the adjustment plate 32 pushes the plastic plate towards the middle of the conveying assembly 2, so that the plastic plate is aligned with the hot press roller 44.

[0034] The working principle and usage process of this utility model: When using this rapid embossing device for plastic product surface texture, the plastic plate is placed at the left end of the conveying component 2, and then the plastic plate is conveyed to the right side by the conveying component 2. During this process, the first hydraulic rod 31 is activated to push the adjusting plate 32 to move, and then the adjusting plate 32 pushes the plastic plate to the middle of the conveying component 2, so that the plastic plate is aligned with the hot pressing roller 44. Then the second hydraulic rod 42 is activated to push the third U-shaped plate 43 and the hot pressing roller 44 downward, so that the hot pressing roller 44 contacts the top surface of the plastic plate. Then the motor 45 is activated to drive the hot pressing roller 44 to rotate, so that the texture can be hot-pressed on the top surface of the plastic plate.

[0035] The movement of the third U-shaped plate 43 is limited by the second limiting rod 46. The threaded rod 47 is rotated by the knob 410, which allows the threaded slider 48 and the limiting plate 49 to move up and down along the side wall of the second limiting rod 46. The distance between the bottom surface of the limiting plate 49 and the bottom surface of the second limiting rod 46 is the same as the downward movement distance of the third U-shaped plate 43 and the hot pressure roller 44. During the downward movement of the hot pressure roller 44 and the third U-shaped plate 43, the limiting plate 49 contacts the top surface of the second U-shaped plate 41, which can limit the movement of the second limiting rod 46 and thus prevent deviations in the downward movement distance of the third U-shaped plate 43 and the hot pressure roller 44.
