Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a pre-shrinking mechanism for wear-resistant fiber fabrics. Background Art

[0002] After pre-shrinkage treatment, the wear-resistant fiber fabric can shrink in both the warp and weft directions, thereby improving the quality of the wear-resistant fiber fabric.

[0003] The existing pre-shrinking treatment usually involves passing the wear-resistant fiber fabric through a pre-shrinking roller with a set temperature, under the action of the pre-shrinking roller, ensuring that the warp and weft directions of the fabric in the wear-resistant fiber fabric remain stable.

[0004] However, the contact area of ​​a single preshrinking roller is limited, resulting in limited preshrinking performance and poor preshrinking stability. Summary of the invention

[0005] The purpose of the utility model is to provide a pre-shrinking mechanism for wear-resistant fiber fabrics with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A preshrinkage mechanism for wear-resistant fiber fabrics, comprising a frame, characterized in that it also includes a bracket 1, a bracket 2, a preshrinkage roller 1, a preshrinkage roller 2, a driving member 1, a driving member 2 and a driving member 3, the bracket 1 and the bracket 2 are respectively connected at two ends of the frame, the two ends of the preshrinkage roller 2 are respectively axially fixed to a lower part of the bracket and a lower part of the bracket 2, the driving member 1 is connected to an upper part of the bracket 1, the driving member 2 is connected to an upper part of the bracket 2, the two ends of the preshrinkage roller 1 are respectively connected to the driving member 1 and the driving member 2, the preshrinkage roller 1 is adjacent to and parallel to the preshrinkage roller 2, the interior of the preshrinkage roller 1 is a cavity into which a fluid heating medium can be injected, the interior of the preshrinkage roller 2 is a cavity into which a fluid heating medium can be injected, the driving member 3 is fixed to the frame and the driving member 3 can drive the preshrinkage roller 1 and the preshrinkage roller 2 to rotate continuously.

[0008] The preshrinkage mechanism of the wear-resistant fiber fabric creatively sets a preshrinkage roller 1 and a preshrinkage roller 2 which are parallel to each other between the bracket 1 and the bracket 2. When the wear-resistant fiber fabric passes between the preshrinkage roller 1 and the preshrinkage roller 2, the preshrinkage roller 1 and the preshrinkage roller 2 are in contact with the two sides of the wear-resistant fiber fabric respectively, so the wear-resistant fiber fabric can be stably preshrinked.

[0009] After the driving member 1 and the driving member 2 act synchronously, the initial height of the preshrinking roller 1 can be changed, thereby adapting to the processing of different wear-resistant fiber fabrics.

[0010] Since the first preshrinking roller and the second preshrinking roller are both filled with fluid heating medium during operation, the wear-resistant fiber fabric can be stably preshrinked when passing through the preshrinking mechanism.

[0011] In the above-mentioned preshrinkage mechanism for wear-resistant fiber fabric, the driving component 1 includes a motor, a driving gear and a driven gear. The motor is fixedly connected to the frame, the driving gear is fixedly connected to the motor shaft, and the driven gear is fixedly connected to the two ends of the preshrinkage roller. The driving gear is meshed with the driven gear.

[0012] When the motor drives the driving gear to rotate continuously, the driven gear rotates together with it. Since the driven gear is fixedly connected to the preshrinking roller 2, it can eventually drive the preshrinking roller 2 to rotate stably.

[0013] In the above-mentioned preshrinkage mechanism for wear-resistant fiber fabrics, there are two preshrinkage rollers, which are horizontally and parallelly arranged between bracket one and bracket two. The driven gear includes driven gear one and driven gear two. Driven gear one is fixedly connected to the end of one of the preshrinkage rollers, and driven gear two is fixedly connected to the end of the other preshrinkage roller.

[0014] In the above-mentioned pre-shrinkage mechanism for wear-resistant fiber fabric, a rotatable transition gear is axially fixedly connected to the bracket one, and two sides of the above-mentioned transition gear are respectively meshed with the driven gear one and the driven gear two.

[0015] Under the action of the transition gear, the two preshrinking rollers can rotate in the same direction, which increases the contact area of ​​the wear-resistant fiber fabric and effectively improves the preshrinking performance.

[0016] In the above-mentioned preshrinkage mechanism for wear-resistant fiber fabric, a positioning sleeve 1 is hingedly connected to a lower end of the driving member, a positioning sleeve 2 is hingedly connected to a lower end of the driving member, and both ends of the above-mentioned preshrinkage roller 1 are respectively inserted into the positioning sleeve 1 and the positioning sleeve 2.

[0017] The first preshrinking roller can be stably connected to the upper part of the second preshrinking roller through the first positioning sleeve and the second positioning sleeve.

[0018] In the above-mentioned preshrinkage mechanism for wear-resistant fiber fabrics, the second bracket includes a fixed plate and a movable plate, the fixed plate is fixedly connected to the frame, the two ends of the preshrinkage roller are axially fixed on the fixed plate, the lower end of the movable plate is hinged on the fixed plate, the second driving member is connected to the upper end of the movable plate, and a positioning structure is provided between the movable plate and the frame that can position the movable plate.

[0019] In the initial state, the movable plate is stably positioned and connected to the fixed plate part under the action of the positioning structure. At this time, both ends of the preshrinking roller are stably positioned, and the entire preshrinking mechanism can perform the preshrinking processing operation normally and stably.

[0020] When the positioning structure causes the movable plate to swing around its hinge, the pre-shrinking roller can be disassembled stably.

[0021] In the above-mentioned pre-shrinkage mechanism for wear-resistant fiber fabrics, the positioning structure includes a positioning rod, a positioning cylinder and a locking pin. The lower end of the positioning cylinder is hinged on the frame, the upper end of the positioning rod is hinged on the movable plate, the upper end of the positioning cylinder is sleeved on the lower end of the positioning rod, and the locking pin is penetrated and connected to the positioning rod and the positioning cylinder.

[0022] When the locking pin is connected to the positioning tube and the positioning rod at the same time, the movable plate can be stably positioned.

[0023] On the contrary, after the locking pin is removed, since the positioning rod can move relative to the positioning cylinder, the movable plate can swing stably around its hinge.

[0024] In the above-mentioned pre-shrinkage mechanism for wear-resistant fiber fabrics, the side of the movable plate has a protruding hinge part one, and the upper end of the positioning rod is hinged to the hinge part one.

[0025] The hinge part 1 provides sufficient position for the upper end of the positioning rod to be hinged.

[0026] In the above-mentioned pre-shrinkage mechanism for wear-resistant fiber fabrics, the side of the frame has a protruding hinge part 2, and the lower end of the above-mentioned positioning cylinder is hinged at the hinge part 2.

[0027] The second hinged portion provides sufficient space for the lower end of the positioning tube to be hinged.

[0028] In the above-mentioned preshrinkage mechanism for wear-resistant fiber fabrics, the height dimension of the lower side of the preshrinkage roller on the frame is A, and the height dimension of the upper side of the second preshrinkage roller on the frame is B, and the above B is greater than A.

[0029] Such a structure can appropriately increase the contact area between the wear-resistant fiber fabric sleeve and the first and second preshrinking rollers, thereby improving the preshrinking efficiency.

[0030] Compared with the prior art, the preshrinkage mechanism of the wear-resistant fiber fabric has a preshrinkage roller 1 and two preshrinkage rollers 2 respectively against the two sides of the wear-resistant fiber fabric. Therefore, the wear-resistant fiber fabric can be stably preshrinked and has relatively high stability.

[0031] At the same time, the movable plate on the bracket 2 can swing around its hinge, which is convenient for loading and unloading the preshrinking roller 21. The loading and unloading is simple, the structure is compact, and the practical value is very high. BRIEF DESCRIPTION OF THE DRAWINGS
