Description

Technical Field

[0001] This utility model relates to the field of hot stamping auxiliary equipment technology, specifically a detachable hot stamping roller support. Background Technology

[0002] In hot stamping equipment, the roller support is responsible for supporting and fixing the roller, ensuring its stability under high-speed rotation and pressure, thereby guaranteeing the stability and consistency of printing quality. The support not only provides robust support but also has positioning and adjustment functions, allowing the roller to operate in precise positions to meet different process requirements. Common structural types include fixed, adjustable, spring-loaded or pneumatic, and composite supports, offering diverse designs that balance rigidity and flexibility. Its working principle primarily relies on a robust frame and guide structure to ensure the roller moves along a predetermined trajectory, while the pressure adjustment mechanism is used to adjust the pressure between the roller and the material to achieve different hot stamping effects. To ensure fine and clear printing, the support frame incorporates a vibration damping design to reduce vibration transmission and improve the stability of equipment operation. Currently, hot stamping rollers with bearing assistance are typically tightly connected to the bearing housing on the support frame via fastening devices (such as bolts, clamping nuts, etc.). The bearings are located at both ends of the roller, serving as support and guides. This design ensures good stability of the roller when rotating at high speeds. However, this structure also means that the connection between the roller and the support frame does not have a quick-release function. During disassembly, multiple bolts or clamping devices usually need to be loosened. On the one hand, the complex disassembly steps increase the time cost of maintenance. On the other hand, improper disassembly may cause damage or mismatch. Especially under conditions of high temperature, frequent operation leading to mechanical wear and dry grease, the fit between the roller and the bearing becomes tighter, increasing the difficulty of disassembly.

[0003] The purpose of this utility model is to provide a detachable hot stamping roller support. The hot stamping roller is concentrically mounted on a support shaft and positioned using a double-disc limiting structure. A hollow shaft shell is installed at each end of the support shaft. The hollow shaft shell is inserted into a raised seat on the base plate through a rectangular boss. After the insertion is completed, the rectangular boss and raised seat are locked by a double-rod elastic locator, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a detachable hot stamping roller support, comprising a base plate, raised seats integrally formed on both sides of the top of the base plate, and a rectangular boss inserted and installed on the top of the raised seats. The top of the rectangular boss is integrally formed with a hollow shaft shell, and a support shaft is rotatably installed between the two hollow shaft shells. A double-disc limiting structure is installed at both ends of the surface of the support shaft. A double-rod elastic positioner is installed on the front and rear outer walls of the raised seats. The double-rod elastic positioner is used to prevent the rectangular boss from falling out of the raised seat.

[0005] Preferably, a T-shaped bushing is fixed at both ends of the rectangular boss, and the inner diameter of the T-shaped bushing is equal to the outer diameter of the support shaft.

[0006] Preferably, the base plate is made of alloy steel, and both sides of the top of the base plate are provided with through holes that can be completely penetrated.

[0007] Preferably, the top of the protrusion seat is provided with a rectangular recessed cavity for the rectangular boss to be inserted.

[0008] Preferably, the dual-disc limiting structure includes limiting discs that are slidably fitted onto both ends of the support shaft surface, a number of bolts that are installed at equal intervals in a ring on the outer wall of the limiting discs, and a number of internal threaded holes provided on the outer wall of the support shaft.

[0009] Preferably, the double-rod elastic positioner includes two guide rods fixed on one outer wall of the protrusion seat, a stop arm fixed at one end of the two guide rods away from the protrusion seat, and a slide seat slidably mounted on one end of the surface of the two guide rods. A protruding post is installed on the outer wall of the slide seat near the protrusion seat. A helical spring is installed on the outer wall of one side of the stop arm. One end of the helical spring is fixedly connected to the outer wall of one side of the slide seat. The rectangular protrusion has a positioning hole concentric with the protruding post inside.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This detachable hot stamping roller support, through a structure consisting of a support shaft, a double-disc limiting structure, a hollow shaft housing, and a rectangular boss that work together, adopts a concentric assembly form of the support shaft and the hot stamping roller, tightly fitting the roller to the support shaft. Then, the hollow shaft housing is inserted into the protrusion on the base plate, forming a modular connection. The assembly method is simple and clear, reducing disassembly steps and operational difficulty, allowing maintenance personnel to complete the disassembly and assembly of the roller in a short time. Secondly, the introduction of the double-disc limiting structure ensures the roller's secure... The device enables precise positioning during installation, fixing the roller in a predetermined position in both the axial and radial directions. This avoids offset or misalignment caused by vibration or improper operation, and ensures that the roller will not loosen or shift during high-speed rotation. The combination of the rectangular boss and the raised seat provides excellent resistance to torsion and eccentric loads, ensuring the roller remains stable during operation. Finally, the double-rod elastic positioner provides appropriate locking force, ensuring a tight and secure connection between the rectangular boss and the raised seat. The locking method of the double-rod elastic positioner also allows operators to quickly loosen or tighten it, greatly facilitating daily maintenance and emergency disassembly.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-6 An embodiment of this utility model provides a detachable hot stamping roller support, including a base plate 1, protrusions 2 integrally formed on both sides of the top of the base plate 1, and a rectangular boss 3 inserted and installed on the top of the protrusions 2. The top of the rectangular boss 3 is integrally formed with a hollow shaft shell 301. A support shaft 5 is rotatably installed between the two hollow shaft shells 301. A double-disc limiting structure is installed at both ends of the surface of the support shaft 5. A double-rod elastic positioner 7 is installed on the front and rear outer walls of the protrusions 2. The double-rod elastic positioner 7 is used to prevent the rectangular boss 3 from falling out of the protrusions 2.

[0020] T-shaped bushings 4 are fixed at both ends of the rectangular boss 3. The inner diameter of the T-shaped bushings 4 is equal to the outer diameter of the support shaft 5. The base plate 1 is made of alloy steel. Both sides of the top of the base plate 1 are provided with through holes 101 that are completely through. The base plate 1 is bolted to the hot stamping equipment through the through holes 101.

[0021] Since the inner diameter of the T-shaped bushing 4 is equal to the outer diameter of the support shaft 5, the T-shaped bushing 4 at both ends of the hollow shaft housing 301 assists in the rotation of the support shaft 5, the limiting disk 6, and the hot stamping roller.

[0022] The top of the protruding seat 2 is provided with a rectangular recessed cavity 201 for the rectangular boss 3 to be inserted. The double-disc limiting structure includes a limiting disk 6 that is slidably fitted on both ends of the surface of the support shaft 5, a number of bolts 601 that are installed at equal intervals in a ring on the outer wall of the limiting disk 6, and a number of internal threaded holes 501 provided on the outer wall of the support shaft 5.

[0023] When using the double-disc limiting structure to limit the hot stamping roller, the operator sets the limiting disk 6 onto the support shaft 5 and slides the limiting disk 6 along the axial direction of the limiting disk 6 so that the bolt 601 is bolted to the internal thread hole 501 at the corresponding position, so as to adjust the fixed position of the limiting disk 6 according to the length specification of the hot stamping roller.

[0024] The double-rod elastic positioner 7 includes two guide rods fixed on one side of the outer wall of the protrusion 2, a stop arm fixed at one end of the two guide rods away from the protrusion 2, and a slide seat slidably mounted on one end of the surface of the two guide rods. A protruding post is installed on the outer wall of the slide seat near the protrusion 2, and a helical spring is installed on the outer wall of one side of the stop arm. One end of the helical spring is fixedly connected to the outer wall of one side of the slide seat. The rectangular boss 3 has a positioning hole 302 concentric with the protruding post. When the double-rod elastic positioner 7 is used to limit the protrusion 2 and the rectangular boss 3, the helical spring on the guide rod forces the slide seat and the protruding post to approach the positioning hole 302 until the protruding post is pushed into the positioning hole 302. Thus, the protruding post and the positioning hole 302 prevent the rectangular boss 3 and the hollow shaft housing 301 from sliding in the horizontal and vertical directions, ensuring that the protrusion 2 and the rectangular boss 3 are stably inserted.

[0025] When it is necessary to separate the raised seat 2 and the rectangular boss 3, the staff can pull the slide to make the boss exit the positioning hole 302. At this time, the spiral spring is in a compressed state, which makes it convenient for the staff to perform daily maintenance and emergency disassembly of the hot stamping roller.

[0026] In this embodiment, the hot stamping roller to be used is first taken out and fitted onto the support shaft 5, ensuring that the axes of the hot stamping roller and the support shaft 5 are concentric. Then, the double-disc limiting structure is assembled onto the support shaft 5, ensuring that the mating surfaces of the support shaft 5 and the double-disc limiting structure are clean and free of impurities. The position of the double-disc limiting structure is adjusted to limit the offset of the hot stamping roller. After the position of the double-disc limiting structure is adjusted, it is tightened. The hollow shaft housing 301 is concentrically fitted onto one end of the support shaft 5, and the bottom end of the rectangular boss 3 is inserted into the top end of the protrusion seat 2 until... After assembling the rectangular boss 3 and the raised seat 2, insert the movable end of the double-rod elastic positioner 7 into the reserved hole of the rectangular boss 3 to ensure that the double-rod elastic positioner 7 provides sufficient locking force. Check that all connection points are tight and that there is no looseness or deviation. Rotate the hot stamping roller to confirm that its rotation is smooth, without jamming or eccentricity. At the same time, check that the action of the double-disc limiting structure is sensitive to ensure that it can effectively limit the deviation of the roller. Finally, test the locking effect of the double-rod elastic positioner 7 to confirm that the hot stamping roller can stably lock the raised seat 2 and the rectangular boss 3 during operation.
