Description

Technical Field

[0001] This utility model relates to the field of fabric inspection machine technology, and in particular to a tension-controllable double-sided fabric inspection machine. Background Technology

[0002] Fabric inspection machines are specialized equipment used in the clothing and textile industry to detect surface defects in various fabrics such as cotton, wool, linen, silk, and chemical fibers. During the fabric inspection process, operators typically visually inspect the fabric for defects (such as color differences and flaws) and record the test results.

[0003] Chinese utility model patent CN218951808U discloses a double-sided fabric inspection machine, comprising a device body, an inspection groove inside the device body, fabric laying plates fixedly installed on both sides of the inner wall of the inspection groove, rotating shafts A movably inserted on both sides of the inner wall of the inspection groove, fabric adjusting rollers A fixedly sleeved on the outer wall of the rotating shafts A, a front detection plate fixedly installed on both sides of the inner wall of the inspection groove, two rotating shafts B movably inserted on both sides of the inner wall of the inspection groove, fabric adjusting rollers B fixedly sleeved on the outer wall of each of the two rotating shafts B, and two rotating shafts C movably inserted on both sides of the inner wall of the inspection groove. Both of the two rotating shafts C have fabric adjusting rollers C fixedly fitted on their outer walls. A back detection plate is fixedly installed on both sides of the inner wall of the fabric inspection groove. A rotating shaft D is movably inserted into both sides of the inner wall of the fabric inspection groove. A fabric adjusting roller D is fixedly fitted on the outer wall of the rotating shaft D. A fabric taking-up rotating shaft is movably inserted into both sides of the inner wall of the fabric inspection groove. A fabric taking-up roller is fixedly fitted on the outer walls of both of the fabric taking-up rotating shafts. Four fabric pressing rollers are movably inserted into both sides of the inner wall of the fabric inspection groove. The outer walls of two of the four fabric pressing rollers are in contact with the output surface of the front detection plate, and the outer walls of the other two of the four fabric pressing rollers are in contact with the output surface of the back detection plate.

[0004] In the process of threading fabric, the fabric of the aforementioned double-sided fabric inspection machine needs to pass through the two pressure rollers between the front inspection plate and the other two pressure rollers between the back inspection plate. Since the front inspection plate and the back inspection plate are in a close fit with the corresponding pressure rollers, the difficulty of threading fabric is increased. Utility Model Content

[0005] To solve the above problems, this utility model provides a tension-controllable double-sided fabric inspection machine.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a tension-controllable double-sided fabric inspection machine, comprising a mounting frame, four guide rollers arranged in a rectangular pattern are rotatably mounted between the side plates on both sides of the mounting frame, two first limiting rollers are rotatably mounted between the side plates on both sides of the mounting frame, two detection plates are slidably disposed on one side plate of the mounting frame, two second limiting rollers are rotatably mounted between the side plates on both sides of the mounting frame, the two first limiting rollers and the two second limiting rollers are all located on the mounting frame between the four guide rollers, one detection plate is in contact with the two first limiting rollers, the other detection plate is in contact with the two second limiting rollers, a take-up roller is rotatably mounted on the mounting frame, and an adjustment mechanism for adjusting the distance between the two detection plates is provided on the mounting frame.

[0007] By adopting the above technical solution, the operator first reduces the distance between the two detection plates by adjusting the mechanism, thereby increasing the distance between one detection plate and the two first limit rollers, and the distance between the other detection plate and the two second limit rollers. At this point, the fabric can be passed sequentially through the four guide rollers, between one detection plate and the two first limit rollers, and between the other detection plate and the two second limit rollers, and then connected to the take-up roller, thus completing the fabric threading process. After threading, the distance between the two detection plates is increased by adjusting the mechanism until one detection plate is in contact with the two first limit rollers, and the other detection plate is in contact with the two second limit rollers. At this point, the take-up roller can be rotated to perform fabric inspection, reducing the difficulty of threading.

[0008] Furthermore, a sliding through hole is provided through the side wall of the mounting bracket at the position corresponding to the detection plate. The adjustment mechanism includes an adjustment component, which includes a connecting plate fixed to the detection plate, a slider fixed to the connecting plate and slidingly engaged with the sliding through hole, and a connecting post disposed on the slider. The slider has an L-shaped structure. The number of sliding through holes, the number of adjustment components, and the number of detection plates are all equal and their positions correspond one-to-one. The adjustment mechanism also includes a rotating component for adjusting the distance between the two connecting posts.

[0009] By adopting the above technical solution, the distance between the two connecting columns is adjusted by rotating the component, thereby changing the distance between the sliders connected to the two connecting columns, the connecting plates connected to the two sliders, and the detection plates connected to the two connecting plates, thus ensuring the normal fabric threading operation of the device.

[0010] Furthermore, the rotating assembly includes a connecting frame fixed to the side wall of the mounting bracket at a position corresponding to the slider, a worm gear rotatably mounted on the connecting frame, a transmission column passing through the connecting frame and rotatably connected, a worm wheel fixedly sleeved on the transmission column and meshing with the worm gear, a rotating motor fixedly mounted on the connecting frame and driving the worm gear to rotate, and an adjusting plate fixedly sleeved on the transmission column. The adjusting plate has an adjusting through hole eccentrically disposed therethrough, and the connecting column slides in conjunction with the adjusting through hole. The number of adjusting through holes is equal to the number of connecting columns, and their positions correspond one-to-one.

[0011] By adopting the above technical solution, after the rotating motor works, it drives the worm to rotate, which causes the worm wheel meshing with the worm, the transmission column connected to the worm wheel, and the adjusting plate connected to the transmission column to rotate. Since the connecting column and the adjusting through hole are in sliding fit, and the adjusting through hole and the adjusting plate are eccentrically set, the purpose of moving the two connecting columns closer to or further away from each other can be achieved.

[0012] Furthermore, one side plate of the mounting bracket has a through guide hole, and an auxiliary component is provided on the mounting bracket. The auxiliary component includes a movable block slidably disposed in the through guide hole, a rotating block disposed through the movable block and rotatably connected, a connecting rod fixed to one end of the rotating block near the inside of the mounting bracket, and a rotating wheel fixed to one end of the connecting rod away from the inside of the mounting bracket. There are two connecting rods, which are symmetrically arranged about the axis of the rotating block.

[0013] By adopting the above technical solution, the fabric is passed between the two connecting rods. At this time, the rotating wheel is rotated, causing the rotating block connected to the rotating wheel and the connecting rod connected to the rotating block to rotate. Since there are two connecting rods and they are symmetrically arranged about the axis of the rotating block, the fabric will be wrapped around the two connecting rods. Then, the moving block moves along the guide through hole until the guide through hole moves to a position close to the take-up roller. During this process, the fabric will pass through four guide rollers, between one detection plate and two first limit rollers, and between another detection plate and two second limit rollers in sequence, which facilitates the fabric feeding operation of the device.

[0014] Furthermore, the mounting frame is provided with a tension adjustment mechanism, which includes an adjustment component. The adjustment component includes a turntable that is rotatably connected to and passes through the side plate of the mounting frame, an adjusting roller fixed to one end of the turntable near the inside of the mounting frame and located inside the mounting frame, and a connecting shaft fixed to one end of the turntable away from the inside of the mounting frame and coaxially arranged with the turntable. There are two adjusting rollers, which are symmetrically arranged about the axis of the turntable. The fabric passes between the two adjusting rollers. The tension adjustment mechanism also includes a drive component for driving the connecting shaft to rotate.

[0015] By adopting the above technical solution, the connecting shaft is driven to rotate by the drive component, so that the turntable connected to the connecting shaft and the two adjusting rollers connected to the adjusting roller mounting frame both rotate until the two adjusting rollers are in close contact with the fabric. By adjusting the degree of contact between the adjusting rollers and the fabric, the tension of the fabric can be adjusted.

[0016] Furthermore, the drive assembly includes a mounting bracket fixed to the mounting frame, a drive motor fixed to the mounting bracket, a drive gear fixedly sleeved on the output end of the drive motor, and a driven gear fixedly sleeved on the connecting shaft and meshing with the drive gear.

[0017] By adopting the above technical solution, after the drive motor works, it drives the active gear to rotate, which causes the driven gear meshing with the active gear and the connecting shaft connected to the driven gear to rotate, thereby achieving the purpose of adjusting the fabric tension.

[0018] Furthermore, the connecting column is rotatably mounted on the slider.

[0019] By adopting the above technical solution, the friction between the connecting column and the adjusting plate is reduced.

[0020] Furthermore, the adjustment assembly also includes a slide rod fixed in the sliding through hole, the slide rod passing through the slider and slidingly engaging with it.

[0021] By adopting the above technical solution, the slider design improves the stability of the slider movement.

[0022] In summary, the present invention has the following beneficial effects: In this application, by setting an adjustment mechanism, the distance between one of the detection plates and the two first limiting rollers, and the distance between the other detection plate and the two second limiting rollers are adjusted when the device is threading the fabric, thereby reducing the difficulty of threading the fabric.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-6As shown in the embodiment of this application, a tension-controllable double-sided fabric inspection machine is disclosed, including a mounting frame 1, an adjustment mechanism 7, an auxiliary component 9, and a tension adjustment mechanism 10. Four guide rollers 2 arranged in a rectangular pattern are rotatably mounted between the side plates on both sides of the mounting frame 1. Two first limiting rollers 3 are rotatably mounted between the side plates on both sides of the mounting frame 1. Two detection plates 4 are slidably disposed on one side plate of the mounting frame 1. Sliding through holes 8 are provided through the side wall of the mounting frame 1 at positions corresponding to the detection plates 4. One side plate of the mounting frame 1 is provided through a guide through hole 11. Two second limiting rollers 5 are rotatably mounted between the side plates on both sides of the mounting frame 1. The two first limiting rollers 3 and the two second limiting rollers 5 are all located on the mounting frame 1 between the four guide rollers 2. One detection plate 4 is in contact with the two first limiting rollers 3, and the other detection plate 4 is in contact with the two second limiting rollers 5. A take-up roller 6 is rotatably mounted on the mounting frame 1. The operator first reduces the distance between the two detection plates 4 using the adjustment mechanism 7, thereby increasing the distance between one detection plate 4 and the two first limit rollers 3, and the distance between the other detection plate 4 and the two second limit rollers 5. At this point, the fabric can be sequentially passed through the four guide rollers 2, between one detection plate 4 and the two first limit rollers 3, and between the other detection plate 4 and the two second limit rollers 5, and then connected to the take-up roller 6, thus completing the fabric threading process. After threading, the distance between the two detection plates 4 is increased again using the adjustment mechanism 7 until one detection plate 4 is in contact with the two first limit rollers 3, and the other detection plate 4 is in contact with the two second limit rollers 5. At this point, the take-up roller 6 can be rotated to inspect the fabric, reducing the difficulty of threading.

[0027] An adjustment mechanism 7 is mounted on the mounting frame 1 and is used to adjust the distance between the two detection plates 4. The adjustment mechanism 7 includes an adjustment component 71 and a rotation component 72. The adjustment component 71 includes a connecting plate 711, a slider 712, and a connecting post 713. The connecting plate 711 is fixed to the detection plate 4, and the slider 712 is fixed to the connecting plate 711 and slides in cooperation with the sliding through hole 8. The slider 712 has an L-shaped structure, and the connecting post 713 is located on the slider 712. The number of sliding through holes 8, the number of adjustment components 71, and the number of detection plates 4 are all equal and their positions correspond one-to-one. By adjusting the distance between the two connecting posts 713 through the rotation component 72, the distances between the sliders 712 connected to the two connecting posts 713, the connecting plates 711 connected to the two sliders 712, and the detection plates 4 connected to the two connecting plates 711 are all changed, thereby ensuring normal fabric threading operation of the device.

[0028] The rotating assembly 72 is used to adjust the distance between the two connecting columns 713. The rotating assembly 72 includes a connecting frame 721, a worm gear 722, a transmission column 723, a worm wheel 724, a rotating motor 725, and an adjusting plate 726. The connecting frame 721 is fixed to the side wall of the mounting frame 1 at a position corresponding to the slider 712. The worm gear 722 is rotatably mounted on the connecting frame 721. The transmission column 723 passes through the connecting frame 721 and is rotatably connected. The worm wheel 724 is fixedly sleeved on the transmission column 723 and meshes with the worm gear 722. The rotating motor 725 is fixed to the connecting frame 721 and drives the worm gear 722 to rotate. The adjusting plate 726 is fixedly sleeved on the transmission column 723. An adjusting through hole 727, eccentrically positioned, is provided through the adjusting plate 726. The connecting columns 713 slide in conjunction with the adjusting through holes 727. The number of adjusting through holes 727 is equal to the number of connecting columns 713, and their positions correspond one-to-one. After the rotating motor 725 starts working, it drives the worm gear 722 to rotate, causing the worm wheel 724 meshing with the worm gear 722, the transmission column 723 connected to the worm wheel 724, and the adjusting plate 726 connected to the transmission column 723 to rotate. Since the connecting column 713 and the adjusting through hole 727 are in sliding fit, and the adjusting through hole 727 and the adjusting plate 726 are eccentrically set, the purpose of moving the two connecting columns 713 closer to each other or further away can be achieved.

[0029] Auxiliary component 9 is mounted on mounting bracket 1. Auxiliary component 9 includes a movable block 91, a rotating block 92, a connecting rod 93, and a rotating wheel 94. The movable block 91 is slidably disposed within the guide hole 11, and the rotating block 92 is disposed through the movable block 91 and rotatably connected. The connecting rod 93 is fixed to one end of the rotating block 92 near the inner end of mounting bracket 1. There are two connecting rods 93, which are symmetrically arranged about the axis of the rotating block 92. The rotating wheel 94 is fixed to one end of the connecting rod 93 away from the inner end of mounting bracket 1. The fabric is passed between the two connecting rods 93. At this time, the rotating wheel 94 is rotated, causing the rotating block 92 connected to the rotating wheel 94 and the connecting rod 93 connected to the rotating block 92 to rotate. Since there are two connecting rods 93 and they are symmetrically arranged about the axis of the rotating block 92, the fabric will be wrapped around the two connecting rods 93. Then, the moving block 91 moves along the guide through hole 11 until the guide through hole 11 moves to a position close to the take-up roller 6. During this process, the fabric will pass through the four guide rollers 2, between one detection plate 4 and two first limit rollers 3, and between another detection plate 4 and two second limit rollers 5 in sequence, which facilitates the fabric feeding operation of the device.

[0030] Tension adjustment mechanism 10 is mounted on mounting frame 1. Tension adjustment mechanism 10 includes adjustment component 101 and drive component 102. Adjustment component 101 includes turntable 1011, adjusting roller 1012 and connecting shaft 1013. Turntable 1011 is mounted through and rotatably connected to the side plate of mounting frame 1. Adjusting roller 1012 is fixed to the end of turntable 1011 near the inside of mounting frame 1 and is located inside mounting frame 1. Two adjusting rollers 1012 are provided and symmetrically arranged about the axis of turntable 1011. Fabric passes between the two adjusting rollers 1012. Connecting shaft 1013 is fixed to the end of turntable 1011 away from the inside of mounting frame 1 and is coaxial with turntable 1011. The drive assembly 102 drives the connecting shaft 1013 to rotate, causing the turntable 1011 connected to the connecting shaft 1013 and the two adjusting rollers 1012 connected to the adjusting roller 1012 mounting bracket 1 to rotate until the two adjusting rollers 1012 are in close contact with the fabric. By adjusting the degree of contact between the adjusting rollers 1012 and the fabric, the tension of the fabric can be adjusted.

[0031] The drive assembly 102 is used to drive the connecting shaft 1013 to rotate. The drive assembly 102 includes a fixed frame 1021, a drive motor 1022, a driving gear 1023, and a driven gear 1024. The fixed frame 1021 is fixed to the mounting frame 1, and the drive motor 1022 is fixed to the fixed frame 1021. The driving gear 1023 is fixedly sleeved on the output end of the drive motor 1022, and the driven gear 1024 is fixedly sleeved on the connecting shaft 1013 and meshes with the driving gear 1023. After the drive motor 1022 operates, it drives the driving gear 1023 to rotate, causing the driven gear 1024 meshing with the driving gear 1023 and the connecting shaft 1013 connected to the driven gear 1024 to rotate, thereby achieving the purpose of adjusting the fabric tension.

[0032] The connecting post 713 is rotatably mounted on the slider 712. This reduces the friction between the connecting post 713 and the adjusting plate 726.

[0033] The adjustment assembly 71 also includes a slide rod 714, which is fixed inside the sliding through hole 8 and passes through the slider 712 and slides in engagement with it. The slide rod 714 improves the stability of the slider 712 during movement.
