Description

Technical Field

[0001] This utility model belongs to the field of fabric positioning and locking technology, and in particular relates to a fabric positioning and locking device for a fabric opening machine. Background Technology

[0002] The tenter frame (also known as a stretching machine or setting machine) is a key piece of equipment in textile finishing processes. Its main function is to flatten, stretch, stabilize the width and set the shape of the fabric to ensure the quality of subsequent processing (such as printing, dyeing, sewing, etc.).

[0003] Existing fabric spreading machines typically use a cutting blade to cut and spread the fabric when spreading it out. However, during the fabric spreading and conveying process, the fabric may shift, causing the subsequent cutting position to change and resulting in uneven left and right edges of the fabric. To address this, we have developed a fabric positioning and locking device for fabric spreading machines. Utility Model Content

[0004] The purpose of this invention is to provide a fabric positioning and locking device for a fabric spreading machine. By moving a moving plate, the extrusion roller is moved, which works in conjunction with the auxiliary roller to position and lock the fabric. This prevents the fabric from shifting during the conveying process, which would cause deviations in the subsequent winding. This solves the problem that in existing fabric spreading and conveying processes, the fabric shifts, which changes the subsequent cutting position and results in uneven left and right edges of the fabric.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a fabric positioning and locking device for a fabric opening machine, including a positioning mechanism and a support frame. The positioning mechanism is provided with an adjustment mechanism on its outer surface. There are two support frames. Locking blocks are slidably connected to the outer surface of each support frame. An auxiliary roller is rotatably connected to the side of the locking blocks that are close to each other. A rotating box is fixedly connected to the top of the locking blocks. A threaded rod is rotatably connected to the inner wall of the rotating box. The fabric is supported by the auxiliary roller.

[0007] Furthermore, the top of the threaded rod passes through the rotating box, and a knob is fixedly connected to the top of the threaded rod. A movable plate is threadedly connected to the outer surface of the threaded rod, and a squeezing roller is rotatably connected to the bottom of the movable plate. The squeezing roller is positioned above the auxiliary roller. The squeezing roller is moved by the movement of the movable plate, so that it cooperates with the auxiliary roller to position and lock the fabric, preventing the fabric from being damaged during the conveying process.

[0008] Furthermore, a support roller is rotatably connected to one side of the locking blocks that are close to each other. A limiting groove is opened on the front side of the support frame located on the front side. A locking block is inserted into the inner wall of the limiting groove. The right side of the locking block extends into the interior of the locking block. A spring is fixedly connected to the front side of the locking block. The front side of the spring is fixedly connected to the inner wall of the locking block. The locking block is limited by pushing the locking block into the limiting groove.

[0009] Furthermore, the adjustment mechanism includes a sliding connection to a moving block, a protective shell fixedly connected to the bottom of the moving block, a motor fixedly connected to the front of the protective shell, and a cutting blade fixedly connected to the output end of the motor via a coupling. The cutting blade is disposed inside the protective shell.

[0010] Furthermore, a limit rod is fixedly connected to the bottom of the movable block, the cutting blade is located on the right side of the cutting blade, and a threaded rod is threadedly connected to the inner wall of the movable block.

[0011] Furthermore, the top of the threaded rod 2 passes through the moving block, and a knob 2 is fixedly connected to the top of the threaded rod 2. A pressing block is rotatably connected to the bottom of the threaded rod 2. The bottom of the pressing block contacts the top of the support frame. A limiting rod 2 is fixedly connected to the top of the pressing block. The outer surface of the limiting rod 2 is slidably connected to the inner wall of the moving block. By rotating the threaded rod 2, the pressing block is pushed downward to cooperate with the support frame to fix the moving block.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses auxiliary rollers. Specifically, the unfolded fabric is placed on the auxiliary rollers on the left and right sides respectively. Then, the knob is turned, which drives the threaded rod to rotate. The rotation of the threaded rod drives the moving plate to move downward. The movement of the moving plate drives the squeezing roller to move, so that it cooperates with the auxiliary rollers to position and lock the fabric, preventing the fabric from shifting during the conveying process and causing deviations in the subsequent winding.

[0014] 2. This utility model uses a movable block, specifically, the rotation of knob two drives the threaded rod two to move, and then the rotation of threaded rod two drives the extrusion block to move upward, so that the extrusion block is disengaged from the support frame. First, the locking of the movable block is released, and then the movable block is pushed to drive the limit rod and the cutting blade to move, so that the position of the cutting blade can be adjusted according to the size of the fabric.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Then, the knob 105 is turned. The rotation of the knob 105 drives the threaded rod 106 to rotate. Then, the rotation of the threaded rod 106 drives the moving plate 107 to move downward. Then, the movement of the moving plate 107 drives the pressing roller 108 to move, so that it cooperates with the auxiliary roller 109 to position and lock the fabric, so as to prevent the fabric from shifting during the conveying process and causing deviation in the subsequent winding.

[0026] The top of the threaded rod 106 passes through the rotating box 104. A knob 105 is fixedly connected to the top of the threaded rod 106.

[0027] A support roller 103 is rotatably connected to one side of the locking blocks 102 that are close to each other. A limit groove 110 is opened on the front of the support frame 101 located on the front. A locking block 111 is inserted into the inner wall of the limit groove 110. The right side of the locking block 111 extends into the interior of the locking block 102. A spring 112 is fixedly connected to the front of the locking block 111. The front of the spring 112 is fixedly connected to the inner wall of the locking block 102.

[0028] The adjustment mechanism 2 includes a sliding connection to the moving block 201. A protective shell 202 is fixedly connected to the bottom of the moving block 201. A motor 203 is fixedly connected to the front of the protective shell 202. A cutting blade 204 is fixedly connected to the output end of the motor 203 via a coupling. The cutting blade 204 is located inside the protective shell 202. Rotating the knob 206 drives the threaded rod 207 to move. Then, rotating the threaded rod 207 drives the extrusion block 208 to move upward, causing the extrusion block 208 to disengage from the support frame 101. The locking of the moving block 201 is first released, and then the moving block 201 is pushed to drive the limit rod 205 and the cutting blade 204 to move, so that the position of the cutting blade 204 can be adjusted according to the size of the fabric.

[0029] The bottom of the movable block 201 is fixedly connected to a limit rod 205, the cutting blade 204 is located on the right side of the cutting blade 204, and the inner wall of the movable block 201 is threadedly connected to a threaded rod 207.

[0030] The top of the threaded rod 207 passes through the moving block 201. The top of the threaded rod 207 is fixedly connected to the knob 206, and the bottom of the threaded rod 207 is rotatably connected to the pressing block 208.

[0031] The bottom of the extrusion block 208 contacts the top of the support frame 101, and the top of the extrusion block 208 is fixedly connected to the limit rod 209. The outer surface of the limit rod 209 is slidably connected to the inner wall of the moving block 201.

[0032] A specific application of this embodiment is as follows: In use, the movable block 201 is first adjusted according to the size of the fabric. First, the knob 206 is rotated, which moves the threaded rod 207. Then, the threaded rod 207 moves the pressing block 208 upwards, causing it to disengage from the support frame 101. The locking of the movable block 201 is then released. Next, the movable block 201 is pushed to move the limiting rod 205 and the cutting blade 204, allowing the position of the cutting blade 204 to be adjusted according to the size of the fabric. Then, the locking block 111 is pulled forward, disengaging it from the limiting groove 110. Finally, the locking block 102 is used to lock the locking block 102 and the support frame 101. The position of roller 103 is adjusted. After adjustment, the fabric is placed on top of support frame 101, so that the fabric is between limit rod 205 and cutting blade 204. The fabric is then cut and unfolded by cutting blade 204. The unfolded fabric is then placed on the front and back auxiliary rollers 109 respectively. Then, knob 105 is turned. The rotation of knob 105 drives threaded rod 106 to rotate. The rotation of threaded rod 106 drives moving plate 107 to move downward. The movement of moving plate 107 drives pressing roller 108 to move, so that it cooperates with auxiliary roller 109 to position and lock the fabric, so as to prevent the fabric from shifting during the conveying process and causing deviation in subsequent winding.
