Description

Technical Field

[0001] This utility model relates to the field of inkjet printer technology, specifically to a fabric wrapping structure for inkjet printers. Background Technology

[0002] In inkjet printers, especially industrial-grade inkjet printers designed for flexible materials such as fabrics and textiles, the fabric winding structure is one of the core components for continuous printing and rewinding of the fabric during the processing. Its performance directly affects printing efficiency, fabric quality, and the ease of subsequent processing.

[0003] The fabric winding structure of existing inkjet printers typically includes a fabric roll shaft, a drive unit such as a servo motor, tensioning components such as tension rollers, spring- or cylinder-driven pressure rollers, and a frame. During operation, the fabric printed by inkjet printing is guided to the fabric roll shaft by a conveyor mechanism. The drive unit drives the fabric roll shaft to rotate, winding the fabric layer by layer onto the roll shaft. However, ordinary winding rollers are often used, which makes it difficult to expand the fabric and adjust for inconsistent tension of the material itself during the winding process. This makes it difficult to achieve synchronous left and right movement and neat winding and unwinding, which can easily lead to deviations in subsequent processing and affect normal operation. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a fabric winding structure for inkjet printers. It can effectively solve the problem that in the prior art, ordinary winding rollers are often used, which makes it difficult to expand the fabric and adjust the inconsistent tension of the material itself during the winding process. This makes it difficult to achieve synchronous left and right movement and neat winding and unwinding, which leads to deviations in subsequent processing and affects normal operation.

[0005] The technical solution adopted by this utility model is: a cloth wrapping structure for an inkjet printer, including a base frame and a back frame. A mounting bracket is fixedly installed on the side of the base frame close to the back frame. A cloth feeding roller, a brush roller assembly and an angle adjustment assembly are fixedly installed on the back frame. An inkjet printing assembly is fixedly installed on the side of the mounting bracket away from the base frame.

[0006] The brush roller assembly includes a mounting plate, an active motor is fixedly mounted at one end near the back frame, a transmission rod is fixedly mounted at the output end of the active motor, a rotating sleeve is provided on the outer surface of the transmission rod, and a brush seat and a brush body are fixedly mounted on the outer wall of the rotating sleeve.

[0007] The angle adjustment assembly includes a second mounting frame, on which a main winding roller, an extension frame, and a secondary winding roller are rotatably mounted along the inner edge.

[0008] Preferably, a mounting end cap is fixedly installed at the end of the transmission rod away from the back frame, and the diameter of the mounting end cap is the same as the diameter of the rotating sleeve.

[0009] By using the above technical solution, the mounting end cap at the end of the transmission rod has the same diameter as the rotating sleeve, which can prevent the rotating sleeve from axially displacing on the transmission rod and allow the brush body to come into contact with the fabric surface.

[0010] Preferably, the brush holder and the bristle body are an integral structure, and multiple identical brush holders and bristle bodies are provided, with the multiple brush holders and bristle bodies arranged in a spiral pattern.

[0011] Through the above technical solution, the spiral distribution creates a continuous spiral trajectory when the bristles come into contact with the fabric surface, which can gradually sweep away dust, lint and other impurities from the fabric surface. At the same time, it generates a stretching force along the length direction for slightly wrinkled fabrics. Meanwhile, the one-piece structure prevents the bristles from falling off, which can improve its service life.

[0012] Preferably, a transmission roller is rotatably mounted on the end of the extension frame away from the main winding roller, and a limiting groove is provided through the inner edge of the mounting frame two.

[0013] With the above technical solution, when the extension frame rotates around the connection point of the mounting frame two, the transmission roller can move closer to or further away from the main winding roller, which can facilitate changing the winding path and tension of the fabric. At the same time, the upper limit groove limits the maximum rotation angle of the extension frame, avoiding excessive adjustment that could cause the fabric to be too tight or too loose.

[0014] Preferably, the end of the mounting bracket two away from the main winding roller is threadedly connected to a first limiting bolt and a second limiting bolt, and the second limiting bolt abuts against the extension bracket.

[0015] Through the above technical solution, the second limiting bolt tightens the extension frame with threads, fixing it at a preset angle to prevent it from easily shifting. At the same time, the first limiting bolt can further lock the position of the second mounting frame and the extension frame to prevent angular deviation caused by vibration.

[0016] Preferably, the brush roller assembly and the angle adjustment assembly are provided in two identical sets, with the two sets of brush roller assemblies and angle adjustment assemblies located at both ends of the inkjet printing assembly, and the two sets of brush roller assemblies and angle adjustment assemblies are on different planes.

[0017] The above technical solution uses a brush roller assembly and an angle adjustment assembly near the feed roller to clean and flatten the fabric, while the brush roller assembly and angle adjustment assembly near the take-up roller can perform secondary finishing on the printed fabric, removing surface ink and smoothing out printing wrinkles. By dissimilarly distributed, interference between the front and rear components can be avoided, allowing the fabric to be transported along a zigzag path.

[0018] Preferably, the back frame is provided with a winding roller and a take-up roller, the winding roller and the take-up roller are located at the end of the inkjet printing assembly away from the feed roller, and the base frame is fixedly installed with a support foot at the end away from the mounting frame.

[0019] The above technical solution releases the fabric to be printed through the winding roller, which is then transferred to the inkjet printing component via various roller assemblies. After printing, the fabric is wound up by the take-up roller. The support feet increase the contact area between the base frame and the ground, reducing vibration during printing.

[0020] Compared with the prior art, the present invention provides a fabric wrapping structure for inkjet printers, which has the following advantages:

[0021] 1. This inkjet printer uses a fabric wrapping structure. The spiral distribution of the brush bristles creates a continuous spiral trajectory when they come into contact with the fabric surface. This gradually removes dust, lint, and other impurities from the fabric surface. At the same time, it generates a stretching force along the length of the fabric for slightly wrinkled fabric. The integrated structure also prevents the brush bristles from falling off, which can improve its service life. When the extension frame rotates around the connection point of the mounting frame two, the drive roller can move closer to or further away from the main wrapping roller. This makes it easy to change the wrapping path and tension of the fabric. At the same time, the upper limit groove limits the maximum rotation angle of the extension frame, preventing excessive adjustment that could cause the fabric to be too tight or too loose.

[0022] 2. This inkjet printer uses a fabric wrapping structure. The brush roller assembly and angle adjustment assembly near the feed roller are responsible for cleaning and flattening the fabric, while the brush roller assembly and angle adjustment assembly near the take-up roller can perform secondary finishing on the printed fabric, removing surface ink and smoothing out printing wrinkles. Through the non-planar distribution, interference between the front and rear components can be avoided, allowing the fabric to be transported along the folded path. Attached Figure Description

[0030] 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.

[0031] Example 1: As Figure 1-6 As shown, the present invention provides a fabric wrapping structure for an inkjet printer, including a base frame 1 and a back frame 4. A mounting bracket 3 is fixedly installed on the side of the base frame 1 near the back frame 4. A fabric feeding roller 5, a brush roller assembly 6 and an angle adjustment assembly 7 are fixedly installed on the back frame 4. An inkjet printing assembly 8 is fixedly installed on the side of the mounting bracket 3 away from the base frame 1.

[0032] The brush roller assembly 6 includes a mounting plate 601, an active motor 602 is fixedly mounted at one end near the back frame 4, a transmission rod 603 is fixedly mounted at the output end of the active motor 602, a rotating sleeve 605 is provided on the outer surface of the transmission rod 603, and a brush seat 606 and a brush body 607 are fixedly mounted on the outer wall of the rotating sleeve 605.

[0033] The angle adjustment assembly 7 includes a second mounting frame 701, and a main winding roller 702, an extension frame 703, and a secondary winding roller 706 are rotatably mounted on the inner edge of the second mounting frame 701.

[0034] Specifically, a mounting end cap 604 is fixedly installed at the end of the transmission rod 603 away from the back frame 4. The diameter of the mounting end cap 604 is the same as the diameter of the rotating sleeve 605. The advantage is that by having the mounting end cap 604 at the end of the transmission rod 603 and the rotating sleeve 605 have the same diameter, axial displacement of the rotating sleeve 605 on the transmission rod 603 can be avoided, allowing the brush body 607 to contact the fabric surface.

[0035] Specifically, the brush holder 606 and the bristle body 607 are an integral structure. Multiple brush holders 606 and bristle bodies 607 are provided, and the multiple brush holders 606 and bristle bodies 607 are arranged in a spiral. The advantage is that the spiral arrangement creates a continuous spiral trajectory when the bristles come into contact with the fabric surface, which can gradually sweep away dust, lint and other impurities from the fabric surface. At the same time, it generates a stretching force along the length direction for slightly wrinkled fabrics. In addition, the integral structure prevents the bristles from falling out, which can improve its service life.

[0036] Specifically, a transmission roller 704 is rotatably mounted on the end of the extension frame 703 away from the main winding roller 702. A limiting groove 705 is provided through the inner edge of the mounting frame 2 701. The advantage is that when the extension frame 703 rotates around the connection point of the mounting frame 2 701, the transmission roller 704 can be brought closer to or away from the main winding roller 702, which can facilitate the change of the fabric winding path and tension. At the same time, the upper limit groove 705 limits the maximum rotation angle of the extension frame 703, avoiding excessive adjustment that would cause the fabric to be too tight or too loose.

[0037] Example 2: Figure 2-6 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, the end of the mounting bracket 2 701 away from the main winding roller 702 is threadedly connected to limit bolt 1 707 and limit bolt 2 708. Limit bolt 2 708 abuts against the extension frame 703. The advantage is that limit bolt 2 708 tightens the extension frame 703 by thread, fixing it at a preset angle and preventing it from easily shifting. At the same time, limit bolt 1 707 can further lock the position of mounting bracket 2 701 and extension frame 703 to prevent angular displacement caused by vibration.

[0039] Specifically, both the brush roller assembly 6 and the angle adjustment assembly 7 are provided with two identical sets. The two sets of brush roller assemblies 6 and angle adjustment assemblies 7 are located at both ends of the inkjet printing assembly 8. The two sets of brush roller assemblies 6 and angle adjustment assemblies 7 are on different planes. The advantage is that the brush roller assembly 6 and angle adjustment assembly 7 near the feed roller 5 are responsible for cleaning and flattening the fabric, while the brush roller assembly 6 and angle adjustment assembly 7 near the take-up roller 10 can perform secondary finishing on the printed fabric, removing surface ink and smoothing out printing wrinkles. Through the non-planar distribution, interference between the front and rear components can be avoided, allowing the fabric to be transported along the zigzag path.

[0040] Specifically, the back frame 4 is equipped with a winding roller 9 and a take-up roller 10. The winding roller 9 and the take-up roller 10 are located at the end of the inkjet printing assembly 8 away from the feed roller 5. The base frame 1 is fixedly installed with a support foot 2 at the end away from the mounting frame 3. The advantage is that the fabric to be printed is released through the winding roller 9, and then transferred to the inkjet printing assembly 8 through each roller assembly. After printing, it is wound up by the take-up roller 10. The support foot 2 increases the contact area between the base frame 1 and the ground, reducing vibration during printing.

[0041] Working Principle: During use, the mounting end cap 604 at the end of the transmission rod 603 has the same diameter as the rotating sleeve 605, preventing axial displacement of the rotating sleeve 605 on the transmission rod 603. This allows the brush body 607 to contact the fabric surface. The spiral distribution ensures that the brush bristles form a continuous spiral trajectory when in contact with the fabric, gradually removing dust, lint, and other impurities. It also provides stretching force along the length of slightly wrinkled fabric. The integrated structure prevents bristle shedding, extending its service life. As the extension frame 703 rotates around the connection point of the mounting frame 701, the transmission roller 704 can move closer to or further away from the main winding roller 702, facilitating changes to the fabric winding path and tension. Simultaneously, the upper limit groove 705 limits the maximum rotation angle of the extension frame 703, preventing over-adjustment that could cause the fabric to be too tight or too loose. Bolt 2 708 tightens the extension frame 703 with threads, fixing it at a preset angle to prevent easy displacement. At the same time, limit bolt 1 707 can further lock the position of mounting frame 2 701 and extension frame 703 to prevent angular deviation caused by vibration. The brush roller assembly 6 and angle adjustment assembly 7 near the feed roller 5 are responsible for cleaning and flattening the fabric, while the brush roller assembly 6 and angle adjustment assembly 7 near the take-up roller 10 can perform secondary finishing on the printed fabric, removing surface ink and smoothing printing wrinkles. Through the non-planar distribution, interference between the front and rear components can be avoided, allowing the fabric to be transported along the folded path. The fabric to be printed is released by the winding roller 9 and transported to the inkjet printing assembly 8 through each roller assembly. After printing, it is wound up by the take-up roller 10. The support foot 2 increases the contact area between the base frame 1 and the ground, reducing vibration during printing.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
