Description

Technical Field

[0001] This utility model relates to the field of textile fabric processing technology, specifically to a tension control component for textile fabrics. Background Technology

[0002] Fabric is an indispensable material in daily life. During the fabric processing and conveying process, it is necessary to regulate the fabric tension to maintain a suitable tension. The device used to regulate the fabric is a tension regulator, which usually consists of multiple sets of fixed-position rotating rollers and adjustable rotating rollers. The tension of the fabric is adjusted by controlling the raising and lowering of the rotating rollers.

[0003] According to patent document CN219688905U, a tension control component for textile fabrics is disclosed, comprising: a support frame assembly, a roller assembly, and a drive mechanism. The support frame assembly includes a base frame, a U-shaped frame, mounting strips, and sliding strips. The U-shaped frame is fixedly connected to the top of the base frame. Two sets of mounting strips are provided and fixedly connected to both sides of the U-shaped frame. The sliding strips are slidably connected to the inside of the U-shaped frame. Three sets of roller assemblies are provided, and the three sets of roller assemblies are horizontally arranged in front of the sliding strips and the two sets of mounting strips. The drive mechanism is installed on the U-shaped frame and is used to drive the sliding strips to move up and down along the U-shaped frame, thereby adjusting the fabric tension. Its beneficial effect is that by setting the roller assembly, when replacing the roller, the device only needs to unscrew the limiting nut and remove the abutment to directly pull out the roller for replacement. Compared with the existing tension control components that use rollers mounted through bearing seats, disassembly and assembly are more convenient.

[0004] Currently, traditional tension control components lack auxiliary detection functions during daily use. They cannot alert workers when the fabric breaks or is short of material, making it difficult for workers to handle the situation in a timely manner and thus affecting work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a tension control component for textile fabrics, in order to solve the problem mentioned in the background art that the current traditional tension control components do not have auxiliary detection functions during daily use, and cannot remind workers when the fabric breaks or is short of material, thus making it impossible for workers to deal with the problem in a timely manner, which in turn affects work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tension control component for textile fabrics, comprising a worktable, a detection mechanism on one side of the worktable, the detection mechanism comprising a housing, a contact switch at the central axis of the top of the housing cavity, springs fixedly connected to both sides of the housing cavity, a rectangular plate fixedly connected to one side of the springs, a movable rod movably connected to one side of the rectangular plate, an adjusting plate movably connected to one side of the movable rod, a connecting plate fixedly connected to the bottom of the adjusting plate, a fixing frame fixedly connected to the bottom of the connecting plate, a fixing plate fixedly connected to the left side of the top of the worktable, and an audible and visual alarm and a PLC controller fixedly connected sequentially from top to bottom on the left side of the fixing plate.

[0007] Preferably, an adjustment mechanism is provided on the other side of the workbench. The adjustment mechanism includes a fixed base, one side of which is fixedly connected to a fixed plate. A motor is fixedly connected to the bottom of the fixed base, and a lead screw is fixedly connected to the output end of the motor. A threaded sleeve is threaded onto the surface of the lead screw. A horizontal plate is fixedly connected to one side of the threaded sleeve. The central axis at the bottom of the horizontal plate is fixedly connected to the housing. Connecting seats are fixedly connected to both sides of the bottom of the horizontal plate. A connecting rod is movably connected to one side of the connecting seat. A connecting shaft is movably connected to one side of the connecting rod. A second roller is movably connected to one side of the connecting shaft. A first roller is movably connected to one side of the fixed frame.

[0008] Preferably, a slide groove is provided on one side of the worktable, and a slider is slidably connected to the inner cavity of the slide groove. The inner cavity of the slider is fixedly connected to the connecting shaft.

[0009] Preferably, a slide rod is slidably connected to the rear side of the inner cavity of the threaded sleeve, and the bottom of the slide rod is fixedly connected to the fixed seat.

[0010] Preferably, the inner cavity of the rectangular plate is slidably connected to a crossbar, and one side of the crossbar is fixedly connected to the shell.

[0011] Preferably, a rectangular groove is provided at the bottom of the housing, and the inner cavity of the rectangular groove is slidably connected to the connecting plate.

[0012] Preferably, the inner cavity of the first roller is fixedly connected to a movable shaft, and both sides of the movable shaft are movably connected to the fixed frame through bearings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By setting up a detection mechanism, during operation, the tension of the fabric will cause the first roller to descend, thereby causing the fixed frame to move. The fixed frame will then move the connecting plate, which will move away from the contact switch. At the same time, it will move the movable rod, which will move the rectangular plate. The rectangular plate will cause the spring to deform. When the fabric breaks or is short of material, the first roller loses its tension. At this time, the spring's thrust will move the rectangular plate, causing the adjusting plate to contact the contact switch, thus activating the audible and visual alarm to alert the staff.

[0015] 2. By setting an adjustment mechanism, the motor is started by the PLC controller. The motor drives the lead screw to rotate, the lead screw drives the threaded sleeve to move, the threaded sleeve drives the horizontal plate to move, thereby driving the first roller shaft to rise or fall. At the same time, it will drive the connecting seat to move, the connecting seat drives the connecting rod to move, the connecting rod drives the connecting shaft to move, and the connecting shaft drives the second roller shaft to move. This achieves a dual adjustment effect, making the tension adjustment range wide. Attached Figure Description

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a technical solution: a tension control component for textile fabric, including a workbench 1, a detection mechanism 2 on one side of the workbench 1, the detection mechanism 2 including a housing 201, a contact switch 202 at the central axis of the top of the inner cavity of the housing 201, springs 203 fixedly connected to both sides of the inner cavity of the housing 201, a rectangular plate 204 fixedly connected to one side of the springs 203, a movable rod 205 movably connected to one side of the rectangular plate 204, an adjusting plate 206 movably connected to one side of the movable rod 205, a connecting plate 207 fixedly connected to the bottom of the adjusting plate 206, a fixing frame 208 fixedly connected to the bottom of the connecting plate 207, a fixing plate 209 fixedly connected to the left side of the top of the workbench 1, and an audible and visual alarm 210 and a PLC controller 211 fixedly connected sequentially from top to bottom on the left side of the fixing plate 209. By setting up the detection mechanism 2, during operation, the tension of the fabric will drive the first roller 306 to descend, thereby causing the fixing... When the frame 208 moves, the fixed frame 208 drives the connecting plate 207 to move. The connecting plate 207 moves away from the contact switch 202, and at the same time, it drives the movable rod 205 to move. The movable rod 205 drives the rectangular plate 204 to move. The rectangular plate 204 causes the spring 203 to deform. When the fabric breaks or is short of material, the first roller shaft 306 loses its tensile force. At this time, the thrust of the spring 203 will drive the rectangular plate 204 to move, so that the adjusting plate 206 contacts the contact switch 202, thereby activating the audible and visual alarm 210 to alert the staff. A crossbar is slidably connected to the inner cavity of the rectangular plate 204, and one side of the crossbar is fixedly connected to the housing 201. By setting the crossbar, the operation of the rectangular plate 204 is stabilized, and the rectangular plate 204 is balanced and supported. A rectangular groove is opened at the bottom of the housing 201, and the inner cavity of the rectangular groove is slidably connected to the connecting plate 207. By setting the rectangular groove, the operation of the connecting plate 207 is stabilized, and the connecting plate 207 is prevented from tilting.

[0023] Please see Figure 1 , Figure 2 and Figure 3An adjustment mechanism 3 is provided on the other side of the workbench 1. The adjustment mechanism 3 includes a fixed base 301. One side of the fixed base 301 is fixedly connected to the fixed plate 209. A motor 302 is fixedly connected to the bottom of the fixed base 301. A lead screw 303 is fixedly connected to the output end of the motor 302. A threaded sleeve 304 is threadedly connected to the surface of the lead screw 303. A horizontal plate 305 is fixedly connected to one side of the threaded sleeve 304. The central axis at the bottom of the horizontal plate 305 is fixedly connected to the housing 201. Connecting seats 3 are fixedly connected to both sides of the bottom of the horizontal plate 305. 07. A connecting rod 308 is movably connected to one side of the connecting seat 307. A connecting shaft 309 is movably connected to one side of the connecting rod 308. A second roller shaft 310 is movably connected to one side of the connecting shaft 309. A first roller shaft 306 is movably connected to one side of the fixing frame 208. By setting the adjusting mechanism 3, the motor 302 is started by the PLC controller 211. The motor 302 drives the lead screw 303 to rotate. The lead screw 303 drives the threaded sleeve 304 to move. The threaded sleeve 304 drives the horizontal plate 305 to move, thereby driving the first roller shaft. When 306 rises or falls, it simultaneously moves the connecting seat 307, which in turn moves the connecting rod 308. The connecting rod 308 then moves the connecting shaft 309, which in turn moves the second roller shaft 310. This achieves a dual adjustment effect, resulting in a wide tension adjustment range. A groove 311 is provided on one side of the worktable 1. A slider 312 is slidably connected to the inner cavity of the groove 311. The inner cavity of the slider 312 is fixedly connected to the connecting shaft 309. By setting the groove 311 and the slider 312, the connecting shaft is stabilized. The operation of 309 stabilizes the second roller 310; a sliding rod is slidably connected to the rear side of the inner cavity of the threaded sleeve 304, and the bottom of the sliding rod is fixedly connected to the fixed seat 301. By setting the sliding rod, the operation of the threaded sleeve 304 is stabilized, preventing the threaded sleeve 304 from rotating; a movable shaft is fixedly connected to the inner cavity of the first roller 306, and both sides of the movable shaft are movably connected to the fixed frame 208 through bearings. By setting the movable shaft and bearings, the operation of the first roller 306 is stabilized, and the first roller 306 is limited.

[0024] Working principle: By setting up the detection mechanism 2, during the working process, the tension of the fabric will drive the first roller 306 to descend, thereby causing the fixed frame 208 to move. The fixed frame 208 drives the connecting plate 207 to move, and the connecting plate 207 will move away from the contact switch 202. At the same time, it will drive the movable rod 205 to move, and the movable rod 205 will drive the rectangular plate 204 to move. The rectangular plate 204 will cause the spring 203 to deform. When the fabric breaks or is short of material, the first roller 306 loses its tension. At this time, the thrust of the spring 203 will drive the rectangular plate 204 to move, thereby causing the adjusting plate 206 to contact the contact switch 202, thereby activating the audible and visual alarm 210 to remind the staff.

[0025] By setting the adjustment mechanism 3, the PLC controller 211 starts the motor 302, which drives the lead screw 303 to rotate. The lead screw 303 drives the threaded sleeve 304 to move, and the threaded sleeve 304 drives the horizontal plate 305 to move, thereby driving the first roller shaft 306 to rise or fall. At the same time, it will drive the connecting seat 307 to move, the connecting seat 307 drives the connecting rod 308 to move, the connecting rod 308 drives the connecting shaft 309 to move, and the connecting shaft 309 drives the second roller shaft 310 to move. This achieves a dual adjustment effect, making the tension adjustment range wide.
