A quick-detachable die-cutting machine roller

Abstract

This utility model discloses a quick-release die-cutting machine roller, relating to the field of die-cutting machine roller technology. The utility model includes a cylinder body and a quick-release maintenance assembly. A filling block is fixedly connected between the two sides of the inner cavity of the cylinder body. Positioning frames are fixedly connected to the top and bottom of the two sides of the inner cavity of the cylinder body. The quick-release maintenance assembly includes two springs, each fixedly connected to a filling block on its opposite side. This utility model utilizes the quick-release maintenance assembly, where springs drive a conical shell to press against a locking mechanism, allowing the locking mechanism to engage with a fixing groove on the surface of the fixing block, thus fixing the rotating shaft. When disassembly is required, a rotating screw drives a top plate to press against the conical shell, preventing the conical shell from pressing against the locking mechanism. At this point, the locking mechanism, through its internal tension spring, allows the locking shell to disengage from the fixing groove, thereby releasing the fixing of the rotating shaft and achieving quick disassembly of the cylinder body.

Description

Technical Field

[0001] This utility model belongs to the field of die-cutting machine roller technology, and in particular relates to a die-cutting machine roller that can be quickly disassembled. Background Technology

[0002] The die-cutting machine roller is the core cylindrical component in die-cutting equipment that processes materials through rotation and pressure. It is usually made of materials such as metal, rubber, or silicone. This component is widely used in the packaging and printing industry, such as die-cutting and creasing of paper boxes, cigarette boxes, and wine boxes, as well as processing of plastic films and leather, supporting automated production lines to improve efficiency and precision.

[0003] Chinese patent application CN215946389U discloses a roller for a plastic film die-cutting machine, including a rotating shaft, two cylinders, and multiple pads. A baffle is located at the right end of the rotating shaft, and a screw is located on the right side of the baffle. The screw is threaded with a nut. The cylinders are cylindrical, with through holes on their sides connecting their two end faces. The pads are cylindrical, with through holes on their sides connecting their two end faces. The end faces of the pads are the same size as the end faces of the cylinders. The through holes and the screw cooperate to create a sliding connection between the cylinders, pads, and screw. This type of roller for a plastic film die-cutting machine can adapt to and accommodate various widths of plastic films, eliminating the need to replace rollers to ensure production and saving equipment costs.

[0004] Although the patent increases the overall length of the roller by filling the spacer between the two cylinders to accommodate wider plastic films, thus enabling it to accommodate various widths of plastic films, it does not allow for quick disassembly and assembly. Currently, the die-cutting machine roller is wrapped around the drive shaft with a semi-circular sleeve and locked with bolts. Disassembling and maintaining the die-cutting machine roller requires removing multiple fixing bolts, making the entire disassembly process time-consuming and labor-intensive, reducing the efficiency of equipment maintenance for workers, and hindering its use.

[0005] To address these issues, we provide a quick-detachable die-cutting machine roller. Utility Model Content

[0006] The purpose of this invention is to provide a quick-disassembly die-cutting machine roller. By combining the quick-disassembly maintenance components and the anti-detachment mechanism, it solves the problem that existing die-cutting machine rollers do not have a quick disassembly function, and that maintenance workers have to spend a long time and use tools such as wrenches to disassemble them, which reduces maintenance efficiency.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a quick-release die-cutting machine roller, comprising a cylinder body and a quick-release maintenance assembly. A filling block is fixedly connected between the two sides of the inner cavity of the cylinder. Positioning frames are fixedly connected to the top and bottom of the two sides of the inner cavity of the cylinder. The quick-release maintenance assembly includes two springs, each with one side fixedly connected to a filling block and the other side fixedly connected to a conical shell. Rotating shafts are provided at the top and bottom of the cylinder body. The opposite sides of the two rotating shafts penetrate into the inner cavity of the cylinder body and are fixedly connected to a fixing block. A fixing groove is provided on the surface of the fixing block. Locking mechanisms are fixedly connected to the top and bottom of the inner cavity of the cylinder body. Screws are threaded onto the inner wall of the rotating shafts. The opposite sides of the two screws penetrate the fixing blocks and are movably connected to a top plate. Anti-detachment mechanisms are provided on the opposite sides of the two screws.

[0009] The present invention is further configured such that the locking mechanism includes a positioning block, the side of the positioning block away from the fixing block is fixedly connected to the inner wall of the cylinder, a retaining shell is sleeved on the surface of the positioning block, a tension spring is fixedly connected to the inner wall of the retaining shell, and a compression ball head is fixedly connected to the bottom of the retaining shell. The positioning block facilitates the installation of the retaining shell, the retaining shell can slide and move on the surface of the positioning block, the tension spring can control the retaining shell to enter the inner cavity of the fixing groove, and the compression ball head can cooperate with the conical shell to control the retaining shell to disengage from the inner cavity of the fixing groove.

[0010] The present invention is further configured such that the anti-detachment mechanism includes a rotating disk, and the opposite sides of the two rotating disks are fixedly connected to the screw. The surface of the rotating shaft is threaded with a threaded sleeve, and the opposite sides of the two threaded sleeves are movably connected with a compression sleeve. The rotating disk allows the operator to easily rotate the screw, and the threaded sleeve can control the position of the compression sleeve during rotation, so that the compression sleeve can compress and lock the rotating disk.

[0011] The present invention is further configured such that the surface of the rotating disk has a notch, the inner wall of the extrusion sleeve is fixedly connected with teeth, and the surface of the threaded sleeve is fixedly connected with anti-slip texture. The notch on the surface of the rotating disk can engage with the teeth inside the extrusion sleeve. When the extrusion sleeve extrudes the rotating disk, it can prevent the rotating disk from rotating by locking the notch and teeth.

[0012] The present invention is further configured such that the inner wall of the positioning frame is slidably connected to the surface of the rotating shaft, and the opposite sides of the two screws are movably connected to the top plate through bearings. The positioning frame can limit the rotation shaft, so that it can be smoothly adjusted up and down. The bearings can prevent the top plate from pressing the conical shell during the rotation of the screws.

[0013] The present invention is further configured such that one side of the tension spring is fixedly connected to the positioning block, and the inner wall of the clamping shell is slidably connected to the positioning block. The tension spring can control the clamping shell to enter the inner cavity of the fixing groove when the extrusion ball is not extruded by the conical shell.

[0014] The present invention is further provided that the surface of the cylinder is provided with a cutter, and the top and bottom of the cylinder are provided with through holes for use with the rotating shaft. The cutter facilitates the die-cutting operation of the cylinder, and the through holes facilitate the installation and use of the rotating shaft.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model utilizes a quick-release maintenance component. A spring drives a conical shell to press against a locking mechanism, allowing the locking mechanism to engage with a fixing groove on the surface of a fixing block, thus securing the rotating shaft. When disassembly is required, a rotating screw drives a top plate to press against the conical shell, preventing the shell from pressing against the locking mechanism. At this point, the locking mechanism, through its internal tension spring, allows the retaining shell to disengage from the fixing groove, thereby releasing the fixing of the rotating shaft and enabling quick disassembly of the cylinder. This solves the problem of needing to remove multiple bolts during the disassembly process of existing die-cutting machine rollers, improving maintenance efficiency.

[0017] 2. This utility model uses an anti-detachment mechanism to rotate the threaded sleeve on the surface of the rotating shaft and drive the extrusion sleeve to move, so that the extrusion sleeve can extrude the rotating disk. The notch on the surface of the rotating disk meshes with the teeth on the inner wall of the extrusion sleeve, preventing the screw from rotating unexpectedly during the operation of the equipment, avoiding accidental contact with the rotating disk that could lead to locking failure, ensuring the stability of the cylinder in the working state, and further improving the reliability of the equipment.

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figure 1-5 This utility model is a quick-release die-cutting machine roller, including a cylinder body 1 and a quick-release maintenance component 4. A filling block 2 is fixedly connected between the two sides of the inner cavity of the cylinder body 1. A positioning frame 3 is fixedly connected between the top and bottom of the two sides of the inner cavity of the cylinder body 1. The quick-release maintenance component 4 includes two springs 41. The opposite side of the two springs 41 is fixedly connected to the filling block 2. The opposite side of the two springs 41 is fixedly connected to a conical shell 42. A rotating shaft 43 is provided at the top and bottom of the cylinder body 1. The opposite side of the two rotating shafts 43 passes through the inner cavity of the cylinder body 1 and is fixedly connected to a fixing block 44. A fixing groove 45 is opened on the surface of the fixing block 44. A locking mechanism 46 is fixedly connected at the top and bottom of the inner cavity of the cylinder body 1. A screw 47 is threadedly connected to the inner wall of the rotating shaft 43. The opposite side of the two screws 47 passes through the fixing block 44 and is movably connected to a top plate 48. An anti-detachment mechanism 49 is provided on the opposite side of the two screws 47.

[0028] Specifically: the filling block 2 is used to improve the strength and weight of the cylinder 1; the positioning frame 3 can position the rotating shaft 43; the spring 41 can control the conical shell 42 to squeeze the locking mechanism 46; the locking mechanism 46 can be inserted into the fixing groove 45 to stably fix the rotating shaft 43 and the fixing block 44; the screw 47 can control the position of the top plate 48; when disassembly is required, the top plate 48 is controlled to squeeze the conical shell 42 so that the conical shell 42 no longer squeezes the locking mechanism 46, which facilitates the disassembly of the cylinder 1; the anti-detachment mechanism 49 can prevent the screw 47 from rotating accidentally during the operation of the cylinder 1.

[0029] Example 2

[0030] Please see Figure 1-5Based on Embodiment 1, the locking mechanism 46 includes a positioning block 461. The side of the positioning block 461 away from the fixing block 44 is fixedly connected to the inner wall of the cylinder 1. A retaining shell 462 is sleeved on the surface of the positioning block 461. A tension spring 463 is fixedly connected to the inner wall of the retaining shell 462. A compression ball head 464 is fixedly connected to the bottom of the retaining shell 462. The anti-detachment mechanism 49 includes a rotating disk 491. The opposite sides of the two rotating disks 491 are fixedly connected to the screw 47. A threaded sleeve 492 is threadedly connected to the surface of the rotating shaft 43. The opposite sides of the two threaded sleeves 492 are movable. The device is connected to a compression sleeve 493. The surface of the rotating disk 491 has a notch. The inner wall of the compression sleeve 493 is fixedly connected with teeth. The surface of the threaded sleeve 492 is fixedly connected with anti-slip texture. The inner wall of the positioning frame 3 is slidably connected to the surface of the rotating shaft 43. The opposite sides of the two screws 47 are movably connected to the top plate 48 through bearings. One side of the tension spring 463 is fixedly connected to the positioning block 461. The inner wall of the retainer 462 is slidably connected to the positioning block 461. The surface of the cylinder 1 is provided with a cutter. The top and bottom of the cylinder 1 are provided with through holes that cooperate with the rotating shaft 43.

[0031] Specifically: the positioning block 461 facilitates the installation of the retaining shell 462; the retaining shell 462 can slide and move on the surface of the positioning block 461; the tension spring 463 controls the retaining shell 462 to enter the inner cavity of the fixing groove 45; the extrusion ball head 464 can cooperate with the conical shell 42 to control the retaining shell 462 to disengage from the inner cavity of the fixing groove 45; the rotating disk 491 facilitates the operator to rotate the screw 47; the threaded sleeve 492 can control the position of the extrusion sleeve 493 during rotation, allowing the extrusion sleeve 493 to press and lock the rotating disk 491; and the notch on the surface of the rotating disk 491 can... The teeth inside the extrusion sleeve 493 mesh with the extrusion sleeve 493. When the extrusion sleeve 493 extrudes the rotating disk 491, it can prevent the disk from rotating by locking the notch and teeth. The positioning frame 3 can limit the rotation shaft 43 so that it can be smoothly adjusted up and down. The bearing can prevent the top plate 48 from extruding the conical shell 42 during the rotation of the screw 47. The tension spring 463 can control the retaining clip 462 to enter the inner cavity of the fixing groove 45 when the extrusion ball head 464 is not extruded by the conical shell 42. The cutter can facilitate the die-cutting operation of the cylinder 1. The through hole facilitates the installation and use of the rotating shaft 43.

[0032] The working principle of this utility model is as follows: When the cylinder 1 needs to be disassembled and maintained, the operator rotates the threaded sleeve 492, which causes the compression sleeve 493 to stop compressing the rotating disk 491. At the same time, the teeth disengage from the inner cavity of the notch, and after unlocking, the rotating disk 491 is rotated. The rotating disk 491 controls the screw 47 to rotate. The screw 47 rotates inside the rotating shaft 43, and through its internal threads, it controls the top plate 48 to compress the inner wall of the conical shell 42. This causes the conical shell 42 to compress the spring 41 and stop compressing the compression ball head 464. At the same time, the tension spring 463 resets, controlling the retaining clip 462 to disengage from the inner cavity of the fixing groove 45, pushing the rotating disk 491 to cause the rotating shaft 43 to enter... The rotating shaft 43 is inserted into the inside of the cylinder 1, making it easy to pull out the cylinder 1. At this time, the operator can directly remove the cylinder 1 for maintenance. When installation is required, the cylinder 1 is placed in the frame, and the two rotating shafts 43 are reinserted into the cylinder 1 through the sleeve. When the top plate 48 re-presses the conical shell 42, the rotating disk 491 is flipped so that the top plate 48 no longer presses the conical shell 42. The spring 41 resets and controls the conical shell 42 to re-press the extrusion ball head 464. The extrusion ball head 464 controls the retainer 462 to enter the fixed groove 45, completing the installation and fixing of the cylinder 1. This solves the problem that multiple bolts need to be removed during the disassembly process of the existing die-cutting machine rollers, and improves maintenance efficiency.

The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific implementation methods described. The present specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the present utility model, so that those skilled in the art can better understand and utilize the present utility model.
