Description

Technical Field

[0001] This utility model belongs to the technical field of hot stamping machines, and specifically relates to a hot stamping machine for ring parts. Background Technology

[0002] In many fields such as home appliances, electronics, and furniture, hot stamping of plastic ring parts has become a common processing procedure to enhance the appearance, added value, and brand identity of products. However, the hot stamping process for plastic ring-shaped parts currently faces numerous technical challenges. Especially when processing large-sized plastic ring-shaped parts, due to their large size, existing hot stamping equipment struggles to guarantee sufficient precision in the positioning and pressing stages, easily leading to positional deviations in the hot stamping pattern and poor accuracy, severely impacting the overall quality and aesthetics of the product.

[0003] Meanwhile, during the hot stamping process, the hot stamping foil is prone to misalignment. Once misalignment occurs, the machine must be stopped for manual correction. This not only interrupts the normal production process and significantly reduces production efficiency, but also increases energy consumption due to frequent start-ups and shutdowns, and causes unnecessary damage to the equipment, thus increasing production costs. Utility Model Content

[0004] The purpose of this utility model is to provide a hot stamping machine for ring parts, which aims to solve the technical problems of poor accuracy and low production efficiency of existing hot stamping machines when hot stamping large-sized plastic ring parts.

[0005] To achieve the above objectives, this utility model provides a ring-shaped hot stamping machine, comprising a main unit, which includes a frame, a paper roll holder, and a die head that can move up and down relative to the frame. The paper roll holder includes a paper feed end and a paper take-up end located on both sides of the frame. The die head includes a transfer roller that can move up and down and rotate. It also includes a worktable located below the die head and a limiting mechanism located on the frame. The worktable includes a support base and a motor base located on the support base that can be adjusted relative to the frame. The side of the motor base away from the frame is provided with... The machine has a rotating shaft parallel to the transfer roller. A servo motor that can drive the rotating shaft is provided on the side of the motor base perpendicular to the rotating shaft. A disc-shaped fixture facing the transfer roller is detachably provided on the rotating shaft. The limiting mechanism includes a telescopic device fixed on the frame. A connecting plate is provided on the telescopic device. The connecting plate moves up and down under the drive of the telescopic device. Multiple auxiliary rods that are detachably provided on the connecting plate are perpendicular to the fixture and located around the circumference of the fixture. Hot stamping foil is placed around the auxiliary rods from the paper feeding end and enters the paper receiving end.

[0006] Preferably, there are three auxiliary rods, namely a first auxiliary rod, a second auxiliary rod, and a third auxiliary rod arranged sequentially on the connecting plate along the paper feeding direction. The first and second auxiliary rods are located on the side of the fixture near the paper feeding end and are arranged adjacent to each other. The third auxiliary rod is located on the side of the fixture near the paper output end and is set lower than the second auxiliary rod. The hot stamping foil passes under the first auxiliary rod from the paper feeding end, then wraps around to the top of the second auxiliary rod, and then wraps around to the bottom of the third auxiliary rod before entering the paper receiving end.

[0007] Preferably, the side of the support base that contacts the motor base is provided with multiple adjusting slide rails parallel to the paper feeding direction.

[0008] Preferably, the connecting plate is provided with multiple mounting holes, and the auxiliary rod is installed in different mounting holes to adjust its position relative to the fixture.

[0009] Preferably, the telescopic device is cylinder two.

[0010] Preferably, the connecting plate is connected to the frame via a slide rail.

[0011] Preferably, the paper roll holder is fixedly connected to the machine head.

[0012] Preferably, the printing head further includes a connecting frame, a cylinder, a movable rod, and a mounting frame. The paper roll is fixed on the connecting frame, and the transfer roller is rotatably mounted on the mounting frame. The cylinder is connected to the mounting frame and can drive the mounting frame to move the transfer roller up and down. The connecting frame and the mounting frame are connected by a slide rail, which assists the cylinder in making the transfer roller move vertically up and down.

[0013] Preferably, the connecting frame is connected to the machine frame via an adjusting screw, and the height of the machine head relative to the machine frame can be adjusted by rotating the adjusting screw.

[0014] The above-mentioned technical solutions of one or more of the ring-shaped hot stamping machines provided in this embodiment of the utility model have at least one of the following technical effects: This utility model discloses a ring-shaped hot stamping machine, which, with the cooperation of the worktable and the machine head, can hot stamp large-sized plastic ring-shaped parts fitted on a disc-shaped fixture. The fixture rotates under the drive of a servo motor-driven rotating shaft, while the transfer roller in the machine head presses down, which can transfer the pattern on the hot stamping paper onto the ring-shaped part, thus achieving effective hot stamping of large-sized ring-shaped parts.

[0015] This utility model discloses a ring-shaped hot stamping machine. With the up-and-down movement of the limiting mechanism and the cooperation of the paper feeding end, paper output end, and transfer roller, the hot stamping paper is further limited by the first, second, and third auxiliary rods. This allows the hot stamping paper to be positioned more accurately, making the pattern transferred onto the plastic ring more precise, avoiding deviations, and improving the overall quality and aesthetics of the product. At the same time, the paper roll is placed on the connecting frame, and the limiting mechanism separates the hot stamping paper from the plastic ring after the transfer is completed, reducing the load on the cylinder in the machine head.

[0016] The ring-shaped hot stamping machine of this utility model, with the setting of the limiting mechanism, can prevent the hot stamping paper from being misaligned during the transfer process, reduce the need for machine downtime for correction, ensure production continuity, improve production efficiency, reduce the defect rate, and at the same time reduce equipment wear and tear and reduce production costs.

[0017] This utility model discloses a ring-shaped hot stamping machine, which, with the cooperation of an adjustable slide rail and detachable components, can hot stamp plastic ring-shaped parts of different specifications, and can reduce the cost of use and improve the applicability of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0027] In one embodiment of this utility model, such as Figure 1-3As shown, a ring-shaped hot stamping machine is provided, including a main unit 10, a worktable 20, and a limiting mechanism 30. The main unit 10 is the main body of the equipment that performs the transfer operation. The worktable 20 is located below the main unit 10. The worktable 20 serves to fix the plastic ring to be processed and drive the ring to rotate to cooperate with the hot stamping operation. A limiting mechanism 30 is provided between the main unit 10 and the worktable 20. The limiting mechanism 30 is located between the main unit 10 and the worktable 20 to assist the main unit 10 in limiting the hot stamping foil during the hot stamping process, ensuring the accurate position of the hot stamping foil. During operation, the plastic ring to be processed is fixed on the worktable 20. The machine head of the main unit 10 moves downward and contacts the plastic ring on the worktable 20. At the same time, the worktable 20 drives the plastic ring to rotate. Under the limiting action of the limiting mechanism 30 on the hot stamping foil, the hot stamping transfer operation on the plastic ring is completed.

[0028] The main unit 10 includes a frame 11, a head unit 12, and a paper roll holder 13.

[0029] The frame 11 serves as the supporting frame for the entire equipment, bearing the weight of all components.

[0030] The printing head 12 can move up and down relative to the frame 11. The printing head 12 includes a transfer roller 121, a connecting frame 122, a mounting frame 123, a cylinder 124, and a movable rod. The transfer roller 121 is rotatably mounted on the mounting frame 123. The transfer roller 121 is circular and has a high-temperature resistant silicone rubber layer on its outer surface. The transfer roller 121 has a heating component inside. The transfer roller 121 serves to transfer the hot stamping foil and plastic ring by contacting each other.

[0031] The cylinder 124 is fixed on the connecting frame 122. The telescopic rod of the cylinder 124 is connected to the mounting frame 123. The cylinder 124 can drive the mounting frame 123 to move the transfer roller 121 up and down, so as to realize the contact and separation between the transfer roller 121 and the plastic ring.

[0032] A movable rod is also provided between the connecting frame 122 and the mounting frame 123. The movable rod is used to assist the cylinder 124 in making the transfer roller 121 move vertically up and down, ensuring the accuracy of the movement of the transfer roller 121 and avoiding the impact of movement deviation on the hot stamping accuracy.

[0033] The connecting frame 122 is connected to the frame 11 via an adjustable screw. This connection method is a mature existing technology that can be easily implemented by those skilled in the art, and will not be described in detail here. By rotating the adjustable screw, the height of the connecting frame 122 on the frame 11 can be adjusted, thereby adjusting the overall height of the machine head 12 to cooperate with other components to adapt to plastic ring parts of different diameters.

[0034] like Figure 2 , 3As shown, the paper roll holder 13 is fixedly connected to the connecting frame 122. The paper roll holder 13 is fixedly mounted on the connecting frame 122, which can reduce the load on the cylinder 124. Especially when dealing with large-sized plastic ring parts, the paper roll holder needs to be relatively long and heavy.

[0035] The paper roll holder 13 includes a paper feed end 131 and a paper take-up end 132 located on both sides of the frame 11. The paper feed end 131 is used to hold the hot foil roll to be used, providing hot foil for the hot foil stamping operation; the paper take-up end 132 is used to recycle the used hot foil waste, so that the hot foil conveying forms a continuous cycle, ensuring the continuity of the hot foil stamping operation. At the same time, the paper feed end 131 and the paper take-up end 132 cooperate to keep the hot foil in a taut, straight and wrinkle-free state.

[0036] The worktable 20 includes a support base 21, a motor base 22, a servo motor 23, a rotating shaft 24, and a fixture 25.

[0037] The support base 21 is a support component that provides an installation platform for components such as the motor base 22.

[0038] The motor base 22 is square and is mounted on the support base 21. Its distance from the frame 11 can be adjusted.

[0039] The side of the support base 21 that contacts the motor base 22 is provided with multiple adjusting slide rails 211 arranged parallel to the paper feeding direction. The motor base 22 can be installed in different adjusting slide rails 211, thereby realizing the adjustment of the distance between the motor base 22 and the frame 11. After the position adjustment is completed, the motor base 22 can be fixed on the adjusting slide rail 211 by screws to adapt to the processing requirements of plastic ring parts of different specifications.

[0040] The servo motor 23 is located on the side of the motor base 22 perpendicular to the rotating shaft 24. In this embodiment, the servo motor 23 is located on the side of the motor base 22 adjacent to the paper receiving end 132. The servo motor 23 is a drive source that can drive the rotating shaft 24 to rotate. The servo motor 23 has the characteristics of high control precision, which can ensure the stability and accuracy of the rotation of the rotating shaft 24, as well as control the speed of the rotation of the rotating shaft 24, thereby ensuring the rotational precision of the plastic ring part.

[0041] The rotating shaft 24 is located on the side of the motor base 22 away from the frame 11 and is arranged parallel to the transfer roller 121. It rotates under the drive of the servo motor 23.

[0042] The fixture 25 is disc-shaped and detachably mounted on the rotating shaft 24 via a bolt connection. The fixture 25 is positioned directly below the transfer roller 121. The plastic ring to be processed is fitted onto the fixture 25. When the transfer roller 121 moves downwards and comes into contact with the plastic ring, the fixture 25 rotates under the drive of the rotating shaft 24. This rotation of the fixture 25 causes the plastic ring to rotate synchronously. Because the outer surface of the transfer roller 121 has a silicone rubber layer and the transfer roller 121 comes into contact with the plastic ring under the action of the cylinder 124, the rotation of the transfer roller 121, driven by the plastic ring, allows the hot stamping foil to perform a comprehensive and uniform hot stamping process on the plastic ring. The detachable design of the fixture 25 facilitates the replacement of the appropriate fixture 25 for different specifications of plastic rings.

[0043] The limiting mechanism 30 includes a second cylinder 31, a connecting plate 32, a mounting hole 33, a first auxiliary rod 34, a second auxiliary rod 35, and a third auxiliary rod 36.

[0044] The telescopic device is a cylinder 31, which is fixed on the frame 11 and located at one end of the frame near the support seat 21. The telescopic rod of the cylinder is set upward and is fixedly connected to the connecting plate 32. The cylinder 31 provides power for the up and down movement of the connecting plate 32. The telescopic action drives the connecting plate 32 to rise and fall, and cooperates with the transfer roller 121 and the fixture 25 to complete the high-quality hot stamping work.

[0045] The connecting plate 32 is connected to the frame 11 via a slide rail. Driven by the second cylinder 31, the connecting plate 32 moves up and down. The slide rail ensures the stability and linearity of the up and down movement of the connecting plate 32.

[0046] The connecting plate 32 is provided with multiple mounting holes 33, which provide positions for the installation of the auxiliary rod and facilitate the adjustment of the position of the auxiliary rod.

[0047] The first auxiliary rod 34, the second auxiliary rod 35, and the third auxiliary rod 36 are detachably mounted on the connecting plate 32 by bolting. They are perpendicular to the fixture 25 and located around the circumference of the fixture 25. The positions of the first auxiliary rod 34, the second auxiliary rod 35, and the third auxiliary rod 36 relative to the fixture 25 are adjusted by installing them in different mounting holes 33. The three auxiliary rods are arranged sequentially on the connecting plate 32 along the paper feeding direction. The first auxiliary rod 34 and the second auxiliary rod 35 are located on the side of the fixture 25 near the paper feeding end 131 and are arranged adjacent to each other. The third auxiliary rod 36 is located on the side of the fixture 25 near the paper output end 132, and the third auxiliary rod 36 is lower than the second auxiliary rod 35.

[0048] The hot stamping foil is fed from the paper inlet 131, passes under the first auxiliary rod 34, then wraps around to the top of the second auxiliary rod 35, and then wraps around to the bottom of the third auxiliary rod 36 before entering the paper delivery end 132. Through this winding method, the three auxiliary rods and the paper roll holder work together to limit the hot stamping foil, ensuring that the hot stamping foil is accurately positioned during the conveying process and preventing it from being misaligned.

[0049] The working principle of this utility model is as follows: A ring-shaped hot stamping machine requires the equipment to be debugged and prepared before operation. Based on the specifications of the plastic ring to be processed, a suitable disc-shaped fixture 25 is selected and installed on the rotating shaft 24. Then, according to the size of the plastic ring and the position to be hot stamped, the motor base 22 is fixed to a suitable position on the support base 21, ensuring that after the plastic ring is fitted onto the fixture 25, the position of the plastic ring to be hot stamped is directly below the transfer roller 121 of the machine head 12.

[0050] Based on the diameter of the plastic ring, the positions of the first auxiliary rod 34, the second auxiliary rod 35, and the third auxiliary rod 36 are adjusted through the mounting holes 33 on the connecting plate 32 to ensure the limiting and adaptation of the auxiliary rods to the hot stamping foil. At the same time, the adjustable screw between the connecting frame and the machine frame 11 is manually rotated to adjust the connecting frame to a suitable height on the machine frame 11, so that after the cylinder 124 extends, the transfer roller 121 can abut against the plastic ring, thereby placing the entire machine head 12 in a suitable working position.

[0051] With cylinder 2 31 in its deep position, hot stamping foil is installed on the paper feed end 131 of the paper roll holder 13. Guided by the support rod on the paper roll holder 13, the hot stamping foil is laid out along a specific path: after being led out from the paper feed end 131, it first passes under the first auxiliary rod 34, then passes over the second auxiliary rod 35, and then passes under the third auxiliary rod 36, finally connecting to the support rod of the paper take-up end 132 and entering the paper take-up end 132. The plastic ring is then placed on the fixture 25. At this time, the paper feed end 131 releases paper, and at the same time, cylinder 2 31 contracts, causing the first auxiliary rod 34, the second auxiliary rod 35, and the third auxiliary rod 36 to descend. At this time, the highest point of the second auxiliary rod 35 is at the same level as the highest point of the plastic ring, and the third auxiliary rod 36 is lower than the second auxiliary rod 35.

[0052] After the equipment is started, cylinder 124 drives the mounting frame 123 to move the transfer roller 121 downward, so that the transfer roller 121 abuts against the plastic ring piece sleeved on the fixture 25. At this time, the transfer roller 121 presses the hot stamping foil between the transfer roller 121 and the plastic ring piece. The transfer roller 121 starts to heat up, the servo motor 23 starts and drives the rotating shaft 24 to rotate, which drives the fixture 25 and the plastic ring piece to rotate synchronously.

[0053] During the rotation of the plastic ring, the transfer roller 121 is driven to rotate, the paper feed end 131 feeds paper, and the paper take-up end 132 takes paper, transferring the pattern on the heated hot stamping foil to the surface of the plastic ring. During this period, the first auxiliary rod 34 and the second auxiliary rod 35 effectively limit the hot stamping foil to prevent it from shifting during the conveying process. The third auxiliary rod 36 makes the hot stamping foil fit tightly against the side of the plastic ring near the paper take-up end 132, ensuring that the hot stamping is successfully transferred to the plastic ring and ensuring the transfer quality.

[0054] After the transfer is completed, cylinder 124 drives the transfer roller 121 to reset upward and disengage from the plastic ring. Servo motor 23 stops working, and cylinder 31 lifts the connecting plate 32, thereby separating the hot stamping foil from the plastic ring and completing one hot stamping operation. The used hot stamping foil is recycled by the paper receiving end 132 to realize the continuous conveying cycle of hot stamping foil.

[0055] Through the above working process, this ring-shaped hot stamping machine can not only adapt to the hot stamping needs of large-sized plastic ring-shaped parts, but also has high transfer accuracy and strong production continuity. At the same time, it can adapt to different specifications of workpieces by adjusting the position of the motor base 22, changing the fixture 25, and adjusting the position of the auxiliary rod, which effectively improves production efficiency and product quality and reduces production costs.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
