Description

Technical Field

[0001] The utility model relates to the technical field of fabric printing equipment, and more specifically, to a device for pressing the edge hair of a fabric, and also to a digital printer with the device for pressing the edge hair of a fabric. Background Art

[0002] Digital printing equipment generally includes a conveyor belt, a sizing mechanism and a digital printing mechanism. The conveyor belt is in a ring structure, supported by guide rollers and driven by a driving mechanism to achieve circular operation. The upper side of the conveyor belt 3 is generally in a horizontal structure, and the upper side of the conveyor belt 3 can carry the fabric to move. The bonding material coated on the surface of the conveyor belt 3 enables the fabric to be flatly attached to the surface of the conveyor belt 3. The fabric moves along with the conveyor belt, first passes through the sizing mechanism to coat a layer of sizing agent on the surface of the fabric, and then passes through the digital printing mechanism for printing. Coating a layer of sizing agent on the surface of the fabric in advance helps to improve the effect of digital printing.

[0003] During the sizing process, a mesh roller is usually used for sizing. The mesh roller rotates in the same direction as the conveying direction of the fabric. When the mesh roller and the fabric are separated, the surface of the mesh roller has an upward movement tendency relative to the fabric, and the fabric hair at the edge of the fabric may be adhered and follow upward, resulting in the fabric hair curling up. The curled-up fabric hair has a certain height. When passing through the digital printing mechanism, it may cause the nozzle of the digital printing to be blocked, and moreover, it will also cause wear on the surface of the nozzle, affecting the normal use of the nozzle.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the Utility Model

Detailed Description of the Embodiment

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] This embodiment discloses a selvedge pressing device, referring to Figure 1 As shown, it includes a guide belt 3 and a hair pressing mechanism 2. The guide belt 3 is annular in structure, supported by a guide roller, and driven by a driving mechanism to realize a cyclic operation. The upper side of the guide belt 3 is roughly horizontal in structure, and the upper side of the guide belt 3 can carry the cloth 4 to move. The adhesive material coated on the surface of the guide belt 3 enables the cloth 4 to be flatly attached to the surface of the guide belt 3 and move with the guide belt 3. The hair pressing mechanism 2 interacts with the cloth 4 on the upper side of the guide belt 3, and can press the hair of the cloth edges 41 on both sides of the cloth 4 to the outside direction to prevent the cloth hair of the cloth edges 41 from curling up.

[0029] Reference Figures 2 - 7 As shown, the hair pressing mechanism 2 includes a hair pressing assembly 23, which includes a track 231, two sliders 232 and two pressing blocks 233. The track 231 is located on the upper side of the guide belt 3 and is arranged along the width direction of the guide belt 3. The two sliders 232 are installed on the track 231, and the two sliders 232 can be adjusted along the track 231 respectively. After the adjustment is completed, the position of the slider 232 can be locked and fixed by bolts.

[0030] The two pressing blocks 233 are respectively mounted on the two sliders 232, and the pressing blocks 233 include a pressing member 2331, and a pressing edge 2336 is provided on the lower side of the pressing member 2331. By adjusting the position of the slider 232, the positions of the two sliders 232 and the two pressing blocks 233 can be adapted to the width of the cloth 4. The two pressing blocks 233 are respectively located above the two cloth edges 41 of the cloth 4 on the upper side of the guide belt 3, and the pressing edge 2336 on the lower side of the pressing member 2331 contacts the upper side of the cloth edge 41.

[0031] When the cloth 4 passes the lower side of the pressing block 233 , the upturned fibers of the cloth edge 41 can be pressed down, thereby preventing the fibers from being upturned.

[0032] In order to improve the pressing effect of the pressing block 233 on the cloth hair, the pressing edge 2336 is set to be parallel to the upper side of the guide belt 3 to ensure that the two can be pressed stably. In addition, along the moving direction of the upper side of the guide belt 3, the pressing edge 2336 is inclined toward the outer edge of the guide belt 3, and the inclination directions of the two pressing edges 2336 are opposite; the pressing edges 2336 of the two pressing blocks 233 are in an eight-shaped structure, which can guide the cloth hair at the cloth edge 41 to both sides, and the upturned cloth hair can be combed outward to avoid the disorderly aggregation of cloth hair, ensuring that the cloth surface can remain flat.

[0033] The pressing member 2331 is provided with a guide surface 2335 inclined downward, and the pressing edge 2336 is formed at the lower side of the guide surface 2335 ; moreover, along the moving direction of the upper side of the guide belt 3 , the guide surface 2335 is inclined downward.

[0034] The inclined guiding surface 2335 can form a downward guiding trend for the lint, and is applicable to lint with a longer length; and an arc-shaped chamfer is formed at the pressing edge 2336, so that the contact position between the pressing member 2331 and the fabric 4 forms a smooth arc-shaped structure, avoiding damage and scratching to the surface of the fabric 4.

[0035] Specifically, the pressing block 233 is mainly divided into two parts. One part is the pressing block main body 2330, and the other part is the above-mentioned pressing member 2331. The pressing block main body 2330 and the pressing member 233 are of a split structure. With the pressing block main body 2330 as the support, the pressing member 2331 is installed on the pressing block main body 2330, and the pressing member 2331 can be disassembled and replaced.

[0036] A connecting portion 2333 is provided on the lower side of the pressing block main body 2330, and the pressing member 233 is fixedly installed on the connecting portion 2333, and the two can be connected and fixed by connecting bolts.

[0037] Furthermore, the pressing block 233 is installed on the slider 232 in a relatively movable structure. On the one hand, it can roughly limit the position of the pressing block 233. On the other hand, the pressing block 233 can move up and down. When pressing, the pressing block 233 mainly falls by its own weight, applies pressure to the edge 41 of the fabric 4, and keeps the pressure within an appropriate range.

[0038] A guiding frame 2320 is fixedly connected to the slider 232. The guiding frame 2320 is provided with a guiding groove 2324. The pressing block 233 is installed in the guiding groove 2324, and the pressing block 233 is limited by the guiding frame 2320. The pressing block 233 can move up and down in the guiding groove 2324, and can basically limit the rotation and lateral movement of the pressing block 233.

[0039] Specifically, the guiding frame 2320 includes a first enclosing portion 2321, a second enclosing portion 2322 and a third enclosing portion 2323. Among them, the first enclosing portion 2321 and the second enclosing portion 2322 are both fixedly connected to the slider 232, and the third enclosing portion 2323 is fixedly connected to the second enclosing portion 2322.

[0040] A guiding groove 2324 is formed between the side surface of the slider 232, the first enclosing portion 2321, the second enclosing portion 2322 and the third enclosing portion 2323. The contour size of the guiding groove 2324 is roughly adapted to the outer peripheral size of the pressing block 233, and is slightly larger than the pressing block 233. The pressing block 233 can be smoothly placed into the guiding groove 2324, and the movement of the pressing block 233 can be limited by the blocking in four directions of the outer periphery. The pressing block 233 can move up in the guiding groove 2324, and the lower side of the pressing block 233 is supported by the guide belt 3 and the fabric 4.

[0041] Furthermore, in this embodiment, the entire hair pressing mechanism 2 can also adopt a lifting and movable structure, and further includes a second lifting table 21 and a second lifter 22. The second lifting table 21 can be adjusted in height through the second lifter 22. Referring to Figure 1 As shown, there are two sets of the second lifting table 21 and the second lifter 22, which are respectively installed on both sides of the equipment. A lifting frame 211 is installed on the upper side of the two second lifting tables 21, and the lifting frame 211 spans across the upper side of the guide belt 3. The track 231 is fixedly installed on the lifting frame 211, and the track 231 and the lifting frame 211 are fixedly connected through a connecting frame 212. Through the lifting action of the second lifter 22, the entire hair pressing assembly 23 can be lifted to expand the distance from the guide belt 3, facilitating the adjustment of the equipment and the replacement of the fabric.

[0042] Furthermore, a limiting portion 2332 is arranged outside the slider 232. The lower side of the limiting portion 2332 can abut against the guide frame 2320 to achieve stroke limiting, and can limit and support the entire pressing block 233. When the hair pressing assembly 23 is lifted, the limiting portion 2332 abuts against the guide frame 2320, and the pressing block 233 can be restricted within the guide frame 2320 to prevent the pressing block 233 from falling off.

[0043] The fabric edge hair pressing device in this embodiment is usually installed and used in a digital printing machine. This type of digital printing machine generally includes the fabric edge hair pressing device in this embodiment, a coating mechanism 1, and a digital printing mechanism. The coating mechanism 1 functions to coat the surface of the fabric on the upper side of the guide belt 3, and can coat the upper surface of the fabric 4 with slurry before digital printing; the digital printing mechanism includes a number of digital printing nozzles, which function to perform digital printing on the surface of the fabric 4.

[0044] The coating mechanism 1 includes a coating mesh roller 13, a first lifting table 11, and a first lifter 12. The coating mesh roller 13 is located above the guide belt 3 and can apply sizing to the surface of the fabric 4 on the upper side of the guide belt 3. The coating mesh roller 13 is installed on the first lifting table 11 and can be adjusted in height through the first lifter 12. When the coating mesh roller 13 descends, the lower side surface of the coating mesh roller 13 contacts the surface of the fabric 4, and sizing coating can be performed on the fabric.

[0045] The coating mesh roller 13 is located in front of the hair pressing assembly 23, and the digital printing mechanism is located behind the hair pressing assembly 23. That is, when the fabric 4 on the upper side of the guide belt 3 is conveyed, it first passes through the coating mesh roller 13, then through the hair pressing assembly 23, and then through the digital printing mechanism.

[0046] At the fabric edge 41, the upturned fabric hair has a certain height and is likely to contact the lower side of the digital printing nozzle, resulting in nozzle clogging, and will also cause wear on the surface of the nozzle, having many adverse effects on the nozzle. Through the hair pressing mechanism 2, the fabric hair can be pressed down, thereby reducing the adverse effects of the fabric hair at the fabric edge 41 on the digital printing nozzle.

[0047] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as the protection scope of the present utility model.
