Description

Technical Field

[0001] The present invention relates to the technical field of fabric tension detection structures, and specifically to a fabric tension detection structure. Background Art

[0002] After the woven fabric is produced, it needs to be wound into a fabric roll. If the tension is too small during the winding process, the fabric roll will not be wound tightly, resulting in repeated winding of the fabric and causing creases on the fabric. If the tension is too large during the winding process, the fabric will be pulled, causing wrinkles on the fabric. Therefore, whether the tension is too large or too small will affect the quality of the fabric.

[0003] Therefore, during the winding of the fabric roll, a tension roller and a tension sensor are required to constantly detect the tension of the fabric to ensure a constant tension to guarantee the quality of the fabric roll.

[0004] However, when detecting the tension of the fabric in the prior art, the general fabric tension detection structure does not have the function of evenly pulling the two ends of the fabric flat. However, before the fabric is wound, it is necessary to ensure that the fabric is completely flat to avoid affecting the detection results of the tension detector. Summary of the Invention

[0005] The purpose of the present invention is to provide a fabric tension detection structure to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions: a clamping assembly, with second support plates arranged at the upper and lower ends in the middle of the rear end of the clamping assembly. A second opening and closing screw is arranged inside the second support plates. Sliding blocks are slidably connected to both sides of the second opening and closing screw. A connecting plate is connected to the inside of the sliding block. Three connecting blocks are connected to the inside of the connecting plate. The connecting blocks extend out from the inside of the clamping assembly. The inner end of the connecting block is connected to a second connecting plate. The inner side of the second connecting plate is rotatably connected to a clamping roller through a rotating shaft; and a tension detection table, with a unwinding roller and a winding roller respectively arranged on both sides of the tension detection table. A tension roller is arranged at the top middle of the tension detection table.

[0007] Preferably, the outer end of the unwinding roller is inserted into the end of a first driving motor arranged outside the tension detection table. The first driving motor can drive the unwinding roller to rotate and unwind the fabric. The outer end of the winding roller is inserted into the end of a second driving motor arranged outside the tension detection table. The second driving motor can drive the winding roller to rotate and wind the fabric.

[0008] Preferably, both ends of the tension roller extend out from both sides of the tension detection table. Tension sensors are connected to both ends of the tension roller. The tension roller can transmit the sensed fabric tension to the tension sensors.

[0009] Preferably, on both sides of the top of the tension detection table, first support plates are welded simultaneously between the unwinding roller and the first driving motor and between the tension roller and the winding roller. Inside the first support plates, first opening and closing screws are provided. One end of each first opening and closing screw is inserted into the end of a lead screw motor provided outside the first support plates, and the lead screw motor can drive the first opening and closing screws to rotate.

[0010] Preferably, the two ends of the first opening and closing screws have opposite threads. Both ends of the first opening and closing screws are simultaneously connected to sliding plates in a sliding manner. The bottom of the sliding plates is connected to a clamping assembly. When the first opening and closing screws rotate, they can drive the two sliding plates to drive the clamping assembly to open and close and slide.

[0011] Preferably, the second opening and closing screw is arranged between two second support plates in the middle outside the clamping assembly. The two ends of the second opening and closing screw have opposite threads. An adjustment knob is provided in the middle of the second opening and closing screw. Rotating the adjustment knob can drive two sliding blocks to open and close and slide on the second opening and closing screw.

[0012] Preferably, when the sliding blocks open and close and slide, they can drive the connecting plate and the second connecting plate connected to the connecting plate through the connecting block to slide synchronously, so that the clamping rollers arranged on the inner sides of the two second connecting plates on the inner side of the clamping assembly can clamp the fabric according to the thickness of the fabric.

[0013] Preferably, extension blocks are simultaneously connected to the upper and lower ends of the middle part of the inner side of the second connecting plate. A telescopic groove is formed at the front end of the extension block. A spring is arranged in the telescopic groove. One end of the spring is connected to the inner wall of the telescopic groove, and the other end is connected to a first brush plate. When the fabric is being transmitted, the first brush plate can clean the fabric.

[0014] Preferably, the inner end of the first brush plate clamps the second brush plate. The first brush plate is clamped in the middle of the second brush plate. Brush hairs are arranged at both ends of the first brush plate. The first brush plate can contract in the middle of the second brush plate.

[0015] Preferably, clamping blocks are arranged on both sides of the clamping opening in the middle of the second brush plate. Clamping grooves are arranged on both sides of the middle part of the first brush plate. The clamping grooves are inserted into the clamping blocks to limit the second brush plate and prevent the second brush plate from falling off.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] A fabric tension detection structure proposed by the present invention. When performing a tension test on the fabric, first, the fabric on the unwinding roller is pulled to the tension roller, and then from the tension roller to the winding roller. After that, the screw rod motor is started, so that the screw rod motor drives the first opening and closing screw rod to rotate, and the sliding plate contracts on the first opening and closing screw rod according to the width of the fabric. At this time, the sliding plate drives the clamping assembly to contract, so that both ends of the fabric are placed between the clamping rollers arranged inside the two second connecting plates on the inner side of the clamping assembly. Then, by screwing the adjusting knob on the second opening and closing screw rod outside the clamping assembly, the adjusting knob drives the second opening and closing screw rod to rotate, and the two sliding blocks on the second opening and closing screw rod start to contract. The contraction of the sliding blocks drives the connecting plate and the second connecting plate connected to the connecting block inside the connecting plate to expand and contract synchronously. The clamping rollers arranged inside the two second connecting plates clamp the fabric according to the thickness of the fabric to prevent the fabric from shrinking during the tension test; while the second connecting plate contracts, it drives the extension block and the first brush plate connected by the spring in the front end telescopic groove of the extension block to contract synchronously. When the first brush plate contracts, it drives the second brush plate to contract synchronously, so that the bristles arranged inside the first brush plate and the second brush plate are closely attached to the upper and lower surfaces of the fabric. When the fabric is conveyed, the first brush plate can clean the upper and lower surfaces of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS
