AI Technical Summary
The existing spreading rollers lack an automatic correction mechanism, which makes the canvas prone to deviation during the brushing process, resulting in uneven fabric distribution and wrinkles, especially on stiff canvas, thus affecting the brushing effect.
Two movable spreading rollers are used, combined with photoelectric switches and driving elements. The photoelectric switches detect the fabric offset and drive the slider to move the spreading rollers to ensure that the fabric is spread evenly and prevent wrinkles from forming.
It effectively prevents wrinkles from forming on the fabric during the conveying process, ensures the normal operation of the abrasive roller, and improves the abrasive effect, especially for hard canvas.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of brushing equipment, specifically a device for producing and processing brushed canvas fabric. Background Technology
[0002] Brushing is a process in the textile industry where fabric is brushed with a brushing machine and emery pads to create a short, fluffy layer on the surface. This process retains the original characteristics of the fabric while giving it a new style, increasing its warmth and softness. It is suitable for winter insulation products and products worn close to the skin.
[0003] Before being napped, existing fabrics need to be spread out by a spreading device before entering the napping mechanism to be napped, flattening the fabric for napping. Most existing spreading mechanisms have two sections of threaded protrusions with opposite directions of rotation on the spreading roller, so that the fabric is spread out to both ends when the spreading roller rotates, such as the utility model with application number 202322000724.3.
[0004] However, existing fabric spreading rollers lack an automatic fabric correction mechanism. If the fabric deviates when entering the abrasive roller, it will cause uneven fabric distribution. The side with more fabric input will not be flattened and will wrinkle. Since canvas is harder than pure cotton fabrics, if the hard fabric with wrinkles enters the abrasive roller for a long time, it will increase the abrasive gap of the abrasive roller, thereby reducing the abrasive effect. Utility Model Content
[0005] To overcome the technical problem that existing napping mechanisms lack the ability to correct fabric deviation, this utility model provides a production and processing device for napped canvas fabric.
[0006] The present invention adopts the following technical solution.
[0007] A fabric brushed canvas production and processing apparatus includes a conveyor belt assembly and brushing rollers and spreading rollers disposed on the conveyor belt assembly. The brushing rollers are disposed at one end of the conveyor belt assembly along its length, and the spreading rollers are mounted on a spreading mechanism. The spreading mechanism includes a slide rail, sliders, a first driving element, and a second driving element. The slide rail is disposed along the width direction of the conveyor belt assembly, and sliders are disposed at both ends of the slide rail. The first driving element is used to drive the sliders to slide along the slide rail. The sliders are equipped with the second driving element and photoelectric switches. The conveyor belt assembly includes a conveyor belt with a reflective surface. The spreading rollers are mounted on the second driving element, and the axial direction of the spreading rollers is disposed along the length direction of the conveyor belt. The photoelectric switches on the two sliders are located outside the axes of the two spreading rollers.
[0008] Optionally, each slider is also equipped with a distance sensor and a reflector.
[0009] Optionally, a first limiting block and a second limiting block are respectively provided at the ends of the two slide rails that are close to each other, and a distance sensor and a reflector are respectively provided on the first limiting block and the second limiting block.
[0010] Optionally, an anti-collision switch is installed on the second limit block.
[0011] Optionally, a display screen is provided on one side of the conveyor belt assembly, and the display screen is electrically connected to the distance sensor.
[0012] Optionally, the conveyor belt assembly also includes a drive roller, a driven roller, and a connecting beam, with the drive roller and driven roller rotatably disposed at both ends of the connecting beam along its length; the conveyor belt is fitted onto the drive roller and driven roller.
[0013] Optionally, first mounting plates are provided on both sides of the outlet end of the connecting beam, and both the spreading roller and the drive roller can be rotatably mounted on the first mounting plates, with the conveyor belt passing through the gap between the spreading roller and the drive roller.
[0014] Optionally, a second mounting plate is provided on both sides of the other end of the connecting beam. The second mounting plate is located between the driving roller and the driven roller, and both ends of the slide rail are provided on the second mounting plate.
[0015] Optionally, the two ends of the first driving element are respectively hinged to the first hinge seat and the second hinge seat; the first hinge seat is mounted on the second mounting plate, and the second hinge seat is mounted on the slider.
[0016] Alternatively, the first driving element is a telescopic cylinder, and the second driving element is a pneumatic motor.
[0017] The beneficial effects of this utility model are as follows:
[0018] This invention features two movable spreading rollers that move along the width of a conveyor belt, with the rollers' axes aligned with the belt's length. Photoelectric switches capable of detecting the conveyor belt are located on the outer sides of the rollers. When fabric enters the belt, the photoelectric switches are blocked by the fabric, preventing the belt from reflecting their signals. At this point, a first driving element on the same side of the blocked photoelectric switch drives a slider to move outwards from the conveyor belt. Simultaneously, the spreading rollers rotate, pulling the fabric outwards. Once the photoelectric switches detect the reflected signal from the conveyor belt, the slider stops moving, while the spreading rollers continue rotating. This invention, by using two movable spreading rollers to pull the fabric towards both ends, effectively prevents wrinkles and, when applied to stiff fabrics like canvas, effectively prevents damage to the brushing rollers.

Detailed Implementation
[0029] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0030] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0031] Example 1:
[0032] like Figures 1-7 The apparatus shown is for producing and processing brushed canvas fabric. It includes a conveyor belt assembly 1 and brushing roller 2 and spreading roller 3 disposed on the conveyor belt assembly 1. The brushing roller 2 is disposed at one end of the length direction of the conveyor belt assembly 1. The spreading roller 3 is mounted on a spreading mechanism 4. The spreading mechanism 4 includes a slide rail 41, sliders 42, a first driving element 43 and a second driving element 47. The slide rail 41 is disposed along the width direction of the conveyor belt assembly 1. Slider 42 is disposed at both ends of the slide rail 41. The first driving element 43 is used to drive the slider 42 to slide along the slide rail 41. The second driving element 47 and a photoelectric switch 45 are mounted on the slider 42. The conveyor belt assembly 1 includes a conveyor belt 13 with a reflective surface. The spreading roller 3 is mounted on the second driving element 47, and the axial direction of the spreading roller 3 is disposed along the length direction of the conveyor belt 13. The photoelectric switches 45 on the two sliders 42 are located outside the axial direction of the two spreading rollers 3. This invention uses two movable spreading rollers 3 to pull the fabric to both sides of the conveyor belt 13, which can effectively prevent the fabric from wrinkling. When applied to hard fabrics such as canvas, it can effectively prevent damage to the abrasive rollers.
[0033] In operation, after the fabric enters the conveyor belt 13, the working state occurs when neither of the photoelectric switches 45 at either end of the slide rail 41 detects the signal reflected by the conveyor belt 13. In this state, the second drive element 47 drives the spreading roller 3 to rotate and pulls the fabric outward in the width direction of the conveyor belt 13. Simultaneously, the first drive element 43 on the same side as the photoelectric switch 45 whose signal is blocked drives the slider 42 to move outward towards the conveyor belt 13. Only after both photoelectric switches 45 at either end of the slide rail 41 can detect the signal reflected by the conveyor belt 13 do the two sliders 42 stop moving away from each other, and the spreading rollers 3 at both ends of the slide rail 41 rotate in opposite directions, simultaneously pulling the fabric towards both sides of the conveyor belt 13.
[0034] When the photoelectric switch 45 at the first end of the slide rail 41 receives the signal reflected by the conveyor belt 13, and the photoelectric switch 45 at the second end of the slide rail 41 is still blocked by the fabric between it and the conveyor belt 13, the spreading rollers 3 at both ends of the slide rail 41 rotate in the same direction, and the two sliders 42 continue to move away from each other along the slide rail 41, so that the spreading roller 3 at the second end of the slide rail 41 feeds the fabric to the first end of the slide rail 41 until the photoelectric switch 45 at the second end of the slide rail 41 detects the signal reflected by the conveyor belt 13, the spreading rollers 3 at both ends of the slide rail 41 rotate in opposite directions, so that the fabric is simultaneously pulled towards both sides of the conveyor belt 13.
[0035] In this embodiment, the surface of the conveyor belt 13 has a coating containing glass microbeads or fluorescent powder.
[0036] In other embodiments, the conveyor belt 13 may also be made of reflective fabrics such as nylon or polyester.
[0037] In this embodiment, the first driving element 43 is a telescopic cylinder, and the second driving element 47 is a pneumatic motor.
[0038] In other embodiments, the slide rail 41 and slider 42 may also be selected as electric guide rail assemblies, without the need for additional drive elements.
[0039] In other embodiments, the second drive element 47 may also be an electric motor or a servo motor, or other element that can drive the spreading roller 3 to rotate.
[0040] Specifically, the conveyor belt assembly 1 also includes a drive roller 11, a driven roller 12, and a connecting beam 14. The drive roller 11 and the driven roller 12 are rotatably disposed at both ends of the connecting beam 14 along its length. The conveyor belt 13 is fitted onto the drive roller 11 and the driven roller 12. A first mounting plate 15 and a second mounting plate 16 are provided on both sides of the other end of the connecting beam 14.
[0041] Specifically, first mounting plates 15 are provided on both sides of the outlet end of the connecting beam 14. Both the abrasive roller 2 and the drive roller 11 can be rotatably mounted on the first mounting plates 15. The conveyor belt 13 drives the fabric through the gap between the abrasive roller 2 and the drive roller 11. The drive roller 11 is driven to rotate by a drive motor 17 installed below the conveyor belt 13.
[0042] The second mounting plate 16 is located between the driving roller 11 and the driven roller 12, and both ends of the slide rail 41 are disposed on the second mounting plate 16. The two ends of the first driving element 43 are respectively hinged to the first hinge seat 431 and the second hinge seat 432; the first hinge seat 431 is mounted on the second mounting plate 16, the second hinge seat 432 is mounted on the slider 42, and the second hinge seat 432 and the second driving element 47 are respectively located on both sides of the slider 42.
[0043] like Figure 5 As shown, the photoelectric switch 45 is located on the top of the slider 42, and the photoelectric switch 45 illuminates the conveyor belt 13 on the other side of the spreading roller 3, thereby avoiding the signal being blocked by the spreading roller 3.
[0044] In this embodiment, a display screen 5 is provided on the outer side of the second mounting plate 16 on one side of the conveyor belt 13. The display screen 5 is a touch display screen and is electrically connected to the photoelectric switch 45, the first driving element 43 and the second driving element 47.
[0045] In this embodiment, a first limiting block 44 and a second limiting block 441 are respectively provided at the ends of the two slide rails 41 that are close to each other, and the second hinge seats 432 of the two sliders 42 are respectively provided on the first limiting block 44 and the second limiting block 441.
[0046] Example 2
[0047] The difference between this embodiment and Embodiment 1 is that:
[0048] like Figure 5 and Figure 6 As shown, the first limiting block 44 and the second limiting block 441 of the two sliders 42 are respectively provided with a distance sensor 46 and a reflector 461, and the display screen 5 is electrically connected to the distance sensor 46.
[0049] In this embodiment, the distance sensor 46 is an infrared distance sensor, and the reflector 461 is used to reflect the signal of the distance sensor 46.
[0050] The distance sensor 46 is used to detect the distance between the two sliders 42 and displays it on the display screen 5. The operator can judge whether the fabric is fully unfolded based on the displayed distance.
[0051] In this embodiment, an anti-collision switch 48 is installed on the second limiting block 441. The anti-collision switch 48 is located on the side facing the other slider 42. When the two sliders 42 approach each other and trigger the anti-collision switch 48, the two first driving elements 43 stop moving.
