Description

Technical Field

[0001] This utility model relates to the technical field of printing machine accessories, specifically a fabric roll roller for a printing machine. Background Technology

[0002] In the textile printing industry, the fabric roll of a printing machine is a key component used for conveying and winding fabric. After the fabric on the roll is wound up, the roll needs to be removed, the rolled fabric taken off, and then a new roll needs to be installed to continue winding the fabric.

[0003] Currently, the fabric roll of a printing machine typically consists of a cylindrical roller body with baffles at both ends to block the fabric. Connecting shafts are mounted on the baffles, allowing the roller body to be rotatably connected to the printing machine frame. The roller body is usually connected to the baffles via a threaded connection. Therefore, when removing the fabric, the roller body must be twisted to disengage the threads before it can be detached from the baffles. Finally, the fabric can be removed. Because the fabric is still wrapped around the roller body, disassembling it is extremely difficult, time-consuming, and labor-intensive. Utility Model Content

[0004] The purpose of this invention is to provide a fabric roll for a printing machine in order to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fabric roll for a printing machine, comprising a roll body, with baffles at both ends of the roll body, and a connecting shaft on the baffles. The roll body is connected to the baffles via a connecting device, the connecting device comprising several locking mechanisms, each locking mechanism comprising a connecting piece and a support assembly. The connecting piece is connected to the roll body via the support assembly, the support assembly having elastic deformation capability, and the support assembly being used to make the connecting piece inclined relative to the roll body in its natural state. An arc-shaped locking strip is connected to the end of the connecting piece away from the support assembly. Several sleeves for locking the arc-shaped locking strips are provided on the baffles, the sleeves being circumferentially distributed on the side of the baffle away from the connecting shaft.

[0006] As a further feature of this invention, the snap-fit ​​mechanism also includes a connecting seat fixedly connected to the roller body, and the connecting piece is hinged to the connecting seat.

[0007] As a further feature of this utility model, the support assembly includes a torsion spring, one end of which is provided with a first connecting strip and the other end with a second connecting strip. A support plate is provided on the connecting seat, the first connecting strip is connected to the support plate, and the second connecting strip is fixedly connected to the side wall of the connecting plate.

[0008] As a further feature of this invention, connecting pins are provided on both sides of the connecting seat, and the torsion spring is sleeved on the connecting pins.

[0009] As a further feature of this invention, the baffle is provided with several through holes, and the sleeve is connected to a threaded rod that passes through the through holes, and a nut is threadedly connected to the threaded rod.

[0010] As a further feature of this invention, the roller body is made of stainless steel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: When installing the roller, the connecting piece can be pressed first to gather it onto the side wall of the roller, causing the support component to elastically deform. Then, the roller is inserted into the position between the sleeves, causing the arc-shaped locking strip to move to the lower position of the sleeve. The connecting piece is then released, allowing the support component to reset and the connecting piece to tilt outward, thereby causing the arc-shaped locking strip to automatically engage inside the sleeve. The sleeve limits the arc-shaped locking strip, thus connecting the roller to the baffle. When the roller needs to be disassembled, simply press the connecting piece to disengage the arc-shaped locking strip from the sleeve, releasing the limit and allowing the roller to be removed. During this process, the fabric will not affect the disassembly of the roller, making the operation convenient, simple, time-saving, and labor-saving. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1 , Figure 2As shown, a fabric roll for a printing machine includes a roll body 1 made of stainless steel, which has high strength and hardness, is not easily corroded, and has good durability. Baffles 2 are provided at both ends of the roll body 1, and connecting shafts 3 are provided on the baffles 2. The roll body 1 is connected to the baffles 2 via a connecting device. The connecting device includes several locking mechanisms, each including a connecting piece 4 and a support assembly. The connecting piece 4 is connected to the roll body 1 via the support assembly, which has elastic deformation capability. The support assembly is used to make the connecting piece 4 inclined relative to the roll body 1 in its natural state. An arc-shaped locking strip 5 is connected to the end of the connecting piece 4 away from the support assembly. Several sleeves 6 for locking the arc-shaped locking strips 5 are provided on the baffles 2, and the sleeves 6 are circumferentially distributed on the baffles 2 away from the connecting shaft. On the other hand, when installing roller 1, the connecting piece 4 can be pressed first to gather it onto the side wall of roller 1, causing the support component to deform elastically. Then, roller 1 is inserted into the position between the sleeve 6, causing the arc-shaped locking strip 5 to move to the position below the sleeve 6. Then, the connecting piece 4 is released, causing the support component to reset and the connecting piece 4 to tilt outward, thereby causing the arc-shaped locking strip 5 to automatically lock into the sleeve 6. The connection between roller 1 and baffle 2 can be achieved by limiting the arc-shaped locking strip 5 through the sleeve 6. When it is necessary to disassemble roller 1, simply press the connecting piece 4 to disengage the arc-shaped locking strip 5 from the sleeve 6 to release the limit and remove roller 1. During this process, the fabric will not affect the disassembly of roller 1. The operation is convenient, simple, time-saving and labor-saving.

[0016] Please see Figure 1 , Figure 2 As shown, the snap-fit ​​mechanism also includes a connecting seat 7 fixedly connected to the roller body 1. The connecting piece 4 is hinged to the connecting seat 7, so the connecting piece 4 can rotate relative to the connecting seat 7, thereby allowing the arc-shaped snap-fit ​​strip 5 to smoothly snap into or out of the sleeve 6. The support assembly includes a torsion spring 8, with a first connecting strip 9 at one end and a second connecting strip 10 at the other end. A support piece 11 is provided on the connecting seat 7. The first connecting strip 9 is connected to the support piece 11, and the second connecting strip 10 is fixedly connected to the side wall of the connecting piece 4. When the connecting piece 4 is pressed, the torsion spring 8 is driven to twist, causing it to undergo elastic deformation. When the connecting piece 4 is released, the torsion spring 8 can automatically rebound and return to its original shape, driving the connecting piece 4 to reset, thus providing elastic support for the connecting piece 4. Connecting pins 12 are provided on both sides of the connecting seat 7, and the torsion spring 8 is sleeved on the connecting pins 12. The support of the torsion spring 8 by the connecting pins 12 can prevent the torsion spring 8 from being deformed and damaged due to excessive force during the torsion process, thereby extending the service life of the torsion spring 8.

[0017] Please see Figure 1-3As shown, several through holes are provided on the baffle 2. A threaded rod 13 is connected to the ferrule 6 through the through holes, and a nut 14 is threaded onto the threaded rod 13. By passing the threaded rod 13 through the through holes and then threading the nut 14 onto the threaded rod 13, the ferrule 6 can be fixedly installed. When the ferrule 6 needs to be repaired, the nut 14 can be unscrewed from the threaded rod 13 to remove the ferrule 6. The operation is relatively convenient, which facilitates the maintenance of the ferrule 6 and extends its service life.
