Description

Technical Field

[0001] This utility model relates to the field of hot stamping equipment technology, and in particular to a hot stamping equipment for processing plastic products. Background Technology

[0002] With the rapid development of modern industry, plastic products have been widely used in various fields due to their advantages such as lightness, durability, and low cost. From daily necessities to high-tech products, plastic products are ubiquitous. In order to increase the aesthetics and recognizability of products and enhance their added value, surface decoration technology has become an important link in the plastic manufacturing industry. Among them, hot stamping, as an efficient and economical surface decoration method, is widely used in the production process of various plastic products. Hot stamping is a technique that transfers specific patterns or text to the surface of a substrate by heating. It usually uses a special material called hot stamping foil, which melts at high temperatures and forms a permanent bond with the surface of the substrate, thereby achieving a beautiful decorative effect.

[0003] Patent CN214688521U discloses a hot stamping device for plastic products. This patent uses a first vertical plate and a limiting rod, with the limiting rod fixed by a limiting hole after rotating 90 degrees. This ensures the movable plate is stably positioned when the second vertical plate and the movable plate are raised. The operator places the plastic sheet on the top of the second guide roller, then places the front end of the movable plate into the first mounting groove, and passes the rotating rod and limiting rod through the limiting hole. After these steps, the limiting rod is rotated 90 degrees again, and the movable plate is fixed by the cooperation between the limiting rod and the limiting hole. This ensures the plastic sheet is properly clamped by the first and second guide rollers. When the power mechanism is activated, it drives the first guide roller to rotate, thereby clamping the movable plate with the second guide roller. The guide rollers work together to convey the plastic sheet to the right. During this process, the tensioning mechanism cooperates with the first and second guide rollers to ensure that the plastic sheet remains taut during conveying. This helps to improve hot stamping efficiency and yield, and enhances the practicality of the equipment. However, this patent still has some shortcomings in practical application. The patent lacks an effective temperature control system and cannot dynamically adjust the hot stamping temperature according to the characteristics of different plastic materials and the specific requirements of the hot stamping pattern. The hot stamping temperature is prone to being too high or too low. If the hot stamping temperature is too high, it will cause damage to the material surface, resulting in color difference or poor pattern transfer. If the hot stamping temperature is too low, it will cause the hot stamping to be weak, which will seriously affect the quality and appearance of the final product, increase the scrap rate, and reduce production efficiency.

[0004] Therefore, there is an urgent need to provide a hot stamping device for processing plastic products with temperature control function. Utility Model Content

[0005] In order to overcome the lack of an effective temperature control system in existing patents, which easily leads to excessively high or low hot stamping temperatures, resulting in problems such as poor hot stamping adhesion, color difference, or poor pattern transfer, this utility model provides a hot stamping device for processing plastic products with temperature control function.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a hot stamping device for processing plastic products, comprising a support plate and a connecting plate. A cylinder is mounted on the upper part of the support plate, and a connecting plate is provided at the end of the cylinder's movable rod. A hot stamping plate is mounted on the bottom of the connecting plate. A connecting frame is fixedly connected to the upper part of the support plate. Symmetrically distributed rotating rods are rotatably mounted on the connecting frame. A limit ring plate is mounted at one end of each rotating rod. A motor is located on the right rear side of the connecting frame. The output shaft of the motor drives the adjacent rotating rods to rotate via a key connection. A guide rod is fixedly connected to the middle of the connecting frame. A first spring is sleeved on the guide rod, and its two ends are respectively connected to the hot stamping plate and the connecting frame. An electric heating plate is located inside the connecting plate, close to the upper part of the hot stamping plate. A temperature controller is installed in the middle of the support plate.

[0007] As a further preferred embodiment, a rotating frame is rotatably mounted on the lower part of the support plate. Multiple limiting frames are evenly spaced on the top of the rotating frame. A sliding plate is slidably arranged inside the limiting frame. Multiple second springs are connected between the sliding plate and the limiting frame. A rubber block is provided on the side of the sliding plate that contacts the plastic product. A motor is mounted on the lower part of the support plate. A dial is provided at the top of the output shaft of the motor. A lever is provided on the dial. A hexagonal intermittent block is assembled on the lower part of the rotating frame. An arc-shaped groove is provided on the hexagonal intermittent block corresponding to the position of the limiting frame, and a through groove is opened between each arc-shaped groove.

[0008] As a further preferred embodiment, each of the limiting frames has a circular hole at its center and at the corresponding limiting frame position on the rotating frame. A fixing plate is fixedly connected to the lower part of the support plate. The fixing plate is located below the rotating frame. A sliding frame is slidably arranged on the fixing plate. A push block is fixedly connected to the top of the sliding frame. A third spring is sleeved on the sliding frame. The two ends of the third spring are respectively connected to the push block and the fixing plate. A handle is connected to the bottom of the sliding frame.

[0009] As a further preferred embodiment, the limiting ring plate is provided with a plastic pull ring.

[0010] As a further preferred embodiment, the bottom of the support plate is provided with an anti-slip plate.

[0011] As a further preferred embodiment, the handle is fitted with an anti-slip sleeve.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device, by assembling a temperature control system consisting of a temperature controller and an electric heating plate, can monitor and precisely adjust the hot stamping temperature in real time, ensuring that the temperature of the electric heating plate is always stable within the set range. This precise temperature control ensures that each hot stamping is carried out at the optimal temperature, avoiding problems such as poor hot stamping, color difference, and poor pattern transfer caused by excessively high or low temperatures, ensuring that the hot stamping pattern is clear and complete, and significantly improving the hot stamping quality and yield.

[0013] 2. Through the coordinated operation of the rotating frame, limiting frame, motor, dial and hexagonal intermittent block, stable multi-station switching is achieved, ensuring that each plastic product can be accurately positioned to the hot stamping station during the hot stamping process. At the same time, automated loading and unloading are realized, thereby greatly improving the level of automation in production and ensuring the continuity and efficiency of production speed.

[0014] 3. Through the combined design of the fixed plate, sliding frame, push block, third spring and handle, the plastic product in the limit frame can be pushed out by simply pulling the handle, so that the sliding frame drives the push block to move upward, so that the material can be picked up manually, thereby simplifying the material picking operation process and reducing labor intensity.

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1: Please refer to Figures 1-4 A hot stamping device for processing plastic products includes a support plate 1. An anti-slip plate 27 is provided at the bottom of the support plate 1 to increase the friction between the support plate 1 and the worktable surface, improving the stability of the equipment. A cylinder 2 is mounted on the upper part of the support plate 1. A connecting plate 3 is provided at the end of the movable rod of the cylinder 2. A detachable hot stamping plate 4 is fitted at the bottom of the connecting plate 3 for easy disassembly and replacement. A connecting frame 5 is fixedly connected to the upper part of the support plate 1. Rotating rods 6, symmetrically distributed on the left and right sides, are rotatably mounted on the connecting frame 5. The right rotating rod 6 is used to release hot stamping foil, while the left rotating rod 6 is used to rewind used hot stamping foil. A limiting ring plate 7 is fitted at the front end of the rotating rod 6 to restrict the movement of the hot stamping foil roll. A plastic pull ring 26 is provided on the limiting ring plate 7. The design allows operators to quickly and easily remove the limiting ring plate 7 from the rotating rod 6. A motor 8 is located on the right rear side of the connecting frame 5. The output shaft of the motor 8 drives the nearby rotating rod 6 to rotate via a key connection, achieving an automatic winding function. A guide rod 9 is fixedly connected to the middle of the connecting frame 5 to guide the hot stamping plate 4. A first spring 10 is sleeved on the guide rod 9, with its two ends connected to the hot stamping plate 4 and the connecting frame 5 respectively. It provides cushioning when the hot stamping plate 4 is pressed down and assists in resetting after hot stamping is completed. An electric heating plate 11 is located inside the connecting plate 3, close to the top of the hot stamping plate 4, to heat the hot stamping plate 4 through heat conduction. A temperature controller 12 is installed in the middle of the support plate 1. The temperature controller 12 is connected to the electric heating plate 11 via an electric wire to control and maintain the required temperature.

[0025] When using this device, firstly, based on the specific plastic material and the desired hot stamping pattern, the temperature of the electric heating plate 11, the pressure of the cylinder 2, and the hot stamping time are set via the temperature controller 12. After the operator sets the temperature, the temperature controller 12 issues a command to start the electric heating plate 11, causing it to quickly rise to the set temperature. Simultaneously, the electric heating plate 11 heats the hot stamping plate 4. When the temperature of the electric heating plate 11 approaches the set value, the temperature controller 12 gradually reduces the heating power to maintain a stable temperature. At this time, the electric heating plate 11 continues to heat at a lower power to ensure that the temperature is always maintained within the set range. During the heating process of the electric heating plate 11, the hot stamping foil roll is released from the rotating rod 6 on the right side, and the other end is fixed to the rotating rod 6 on the left side. After all parameters of the device are adjusted, the plastic product to be hot-stamped is placed under the hot stamping foil, and cylinder 2 is started. Cylinder 2 begins to work, and its movable rod pushes the connecting plate 3 downward, so that the hot stamping plate 4 presses the hot stamping foil tightly onto the surface of the plastic product. During this process, the temperature controller 12 continuously monitors the temperature of the electric heating plate 11 to ensure precise temperature control. This feature ensures temperature consistency even during long-term continuous operation, ensuring that the hot stamping pattern is transferred clearly and completely onto the plastic product, thereby improving production efficiency and product quality. When the preset hot stamping time is reached, cylinder 2 retracts, releasing pressure, and the hot stamping plate 4 leaves the surface of the plastic product. Finally, motor 8 drives the right rotating rod 6 to roll up the used hot stamping foil, preparing it for the next hot stamping.

[0026] Example 2: Based on Example 1, please refer to... Figure 5 and Figure 6 A rotating frame 13 is rotatably mounted on the lower part of the support plate 1. Six evenly spaced limiting frames 17 are distributed on the top of the rotating frame 13 for placing the plastic products to be hot-stamped. A sliding plate 18 is slidably installed inside each limiting frame 17. Two second springs 19 connect the sliding plate 18 to the limiting frame 17. The cooperation between the sliding plate 18 and the second springs 19 effectively fixes plastic products of different sizes and shapes, ensuring product stability during hot-stamping. A rubber block 20 is provided on the side of the sliding plate 18 that contacts the plastic product to increase... To increase friction and prevent plastic products from sliding and to protect the surface of plastic products from damage, a motor 14 is installed at the lower part of the support plate 1. A dial 15 is provided at the top of the output shaft of the motor 14. A lever 1501 is provided on the dial 15. A hexagonal intermittent block 16 is assembled at the lower part of the rotating frame 13. An arc-shaped groove is provided on the hexagonal intermittent block 16 at the position corresponding to the limit frame 17, and a through groove is opened between each arc-shaped groove. By cooperating with the dial 15, lever 1501 and the arc-shaped groove and through groove on the hexagonal intermittent block 16, stable multi-station switching can be achieved.

[0027] Please see Figure 7Each of the limiting frames 17 has a circular hole at its center and at the corresponding position on the rotating frame 13. A fixing plate 21 is fixedly connected to the lower part of the support plate 1, and the fixing plate 21 is located below the rotating frame 13. A sliding frame 22 is slidably mounted on the fixing plate 21, and a push block 23 is fixedly connected to the top of the sliding frame 22 for pushing out the plastic product inside the limiting frame 17. A third spring 24 is sleeved on the sliding frame 22, and the two ends of the third spring 24 are respectively connected to the push block 23 and the fixing plate 21. The sliding frame 22 is provided with a rebound force to ensure that the push block 23 can automatically return to its original position after the push-out action is completed. The bottom end of the sliding frame 22 is connected to a handle 25. The operator can control the movement of the sliding frame 22 by pulling or pushing the handle 25, thereby realizing the push-out and reset of the plastic product. The handle 25 is covered with an anti-slip sleeve 28 to improve the grip comfort and safety of the handle 25 and increase the friction of the surface of the handle 25, effectively preventing the operating handle 25 from slipping due to hand sweat, oil stains or other factors.

[0028] Before hot stamping, the plastic product is placed in the limiting frame 17. The sliding plate 18 will automatically move outward to the appropriate position under the action of the second spring 19 to clamp the plastic product. The rubber block 20 increases the friction between the plastic product and the sliding plate 18, ensuring that the product will not move during the hot stamping process. Next, the motor 14 is started, and the dial 15 at the top of its output shaft rotates clockwise, causing the lever 1501 of the dial 15 to enter the elongated through slot, pushing the hexagonal intermittent block 16 to rotate to a certain angle, so that one of the limiting frames 17 moves to the hot stamping station. As the dial 15 continues to rotate, the lever 1501 leaves the elongated through slot, achieving a brief pause. At this time, the limiting frame 17 remains stationary, waiting for the hot stamping operation. During this process, the dial 15 moves along the arc... As the hot stamping process is completed, the lever 1501 moves into the next through slot, pushing the hexagonal intermittent block 16 to rotate and replace the limit frame 17, thus achieving automated loading and unloading. New unstamped products are sent into the hot stamping station to prepare for the next round of operations, while the stamped products are removed from the hot stamping station. At this time, the operator pulls the handle 25 to move the sliding frame 22 upward. The push block 23 enters the interior of the limit frame 17 through the round holes on the limit frame 17 and the rotating frame 13, smoothly pushing out the plastic product. The operator can easily remove the finished product from the limit frame 17. Subsequently, the sliding frame 22 is released, and the third spring 24 returns to its original position. The sliding frame 22 drives the push block 23 to automatically return to its original position, ready for the next push-out action.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
