Description

Technical Field

[0001] The present application relates to the technical field of cloth production, and in particular to a top roller braking device for cloth printing and dyeing. Background Art

[0002] The top roller is a roller located on the top of the printing and dyeing equipment support in fabric printing and dyeing production. When the fabric moves forward or backward, the friction between the fabric and the top roller causes the top roller to rotate forward or reverse. The top roller mainly plays a guiding or tensioning role.

[0003] When the printing and dyeing equipment stops conveying fabric, the fabric near the top roller will move forward a certain distance due to inertia and the weight of the fabric itself, causing the fabric below the top roller to become too loose and overlap. When conveying again, the overlapped fabric is prone to abnormal winding. Therefore, when stopping fabric conveyance, the fabric near the top roller should be kept at a standstill as much as possible. Utility Model Content

[0004] The present application provides a top roller brake device for fabric printing and dyeing. When the fabric is stopped, the brake device limits the rotation of the top roller, and utilizes the friction between the top roller and the fabric to keep the fabric in its vicinity in a stationary state.

[0005] This application is implemented through the following technical solutions:

[0006] A top roller braking device for cloth printing and dyeing, comprising:

[0007] A brake member, the brake member being connected to one end of the sky roller to rotate synchronously with the sky roller;

[0009] a clamping mechanism, the clamping mechanism being elastically slidably connected to the mounting seat and being used to clamp the brake member;

[0010] A controller connected to the clamping mechanism to control the clamping mechanism to perform a clamping action;

[0011] When the clamping mechanism clamps the braking member, the braking member drives the clamping mechanism to move so that the clamping mechanism slides elastically on the mounting seat.

At the same time, the clamping mechanism is elastically slidably connected to the mounting seat. When the sky roller is restricted from rotating, the fabric can be transported forward a short distance under the action of inertia to prevent the surface quality of the fabric from being affected by friction when the sky roller stops suddenly. When the clamping mechanism slides to the limit position, the sky roller rotates under the action of the brake part under the action of elasticity, so that the fabric moves back a short distance to prevent excessive tension of the fabric before the sky roller.

[0014] A clamping seat, the clamping seat being elastically slidably connected to the mounting seat;

[0015] a first clamping arm, the first clamping arm being elastically rotatably connected to the clamping seat;

[0017] A driving member is respectively coupled with the first clamping arm and the second clamping arm to drive the first clamping arm and the second clamping arm to rotate elastically on the clamping seat.

[0018] In some optional embodiments, the driving member is configured as an electromagnet, wherein the first clamping arm and the second clamping arm are respectively provided with a first attraction portion and a second attraction portion for attracting the driving member.

[0019] In some optional embodiments, an arc-shaped sliding groove is constructed on the mounting seat, and a sliding block adapted to the arc-shaped sliding groove is provided on the clamping seat.

[0023] In some optional embodiments, the braking member is configured as a disc, and the braking member is coaxially connected to the top roller.

[0024] In some optional embodiments, friction plates are attached to the two disc surfaces of the brake member.

[0025] In some optional embodiments, the mounting seat is provided with a strip hole, and a connecting bolt for connecting to the printing and dyeing equipment bracket is arranged in the strip hole.

[0026] Compared with the prior art, this application has the following advantages and beneficial effects:

[0027] The present application provides a sky roller brake device for fabric printing and dyeing, in which the brake part is connected to one end of the sky roller, and then the brake part is clamped by a clamping mechanism to limit the rotation of the brake part, thereby limiting the rotation of the sky roller. At the same time, the clamping mechanism is elastically slidably connected to the mounting seat. When the sky roller is restricted from rotating, the fabric can be transported forward a short distance under the action of inertia to prevent the surface quality of the fabric from being affected by friction when the sky roller stops suddenly.

DETAILED DESCRIPTION

[0036] In order to make the objectives, technical solutions and advantages of this application more clear, the present application is further described in detail below in conjunction with examples and drawings. The schematic implementation methods of this application and their descriptions are only used to explain this application and are not intended to limit this application.

[0037] like Figure 1-Figure 5 As shown, an embodiment of the present application provides a sky roller brake device for fabric printing and dyeing, which includes a brake member 1, a mounting seat 2, a clamping mechanism 3 and a controller; the brake member 1 is used to be connected to one end of the sky roller 4 to rotate synchronously with the sky roller 4, which means that the rotation of the sky roller 4 can also be restricted after a braking force is applied to the brake member 1; the mounting seat 2 is used to be fixedly connected to a bracket of the printing and dyeing equipment; the clamping mechanism 3 is elastically slidably connected to the mounting seat 2, and the clamping mechanism 3 is used to clamp the brake member 1; the controller is connected to the clamping mechanism 3 to control the clamping action of the clamping mechanism 3; when the clamping mechanism 3 clamps the brake member 1, the brake member 1 drives the clamping mechanism 3 to move so that the clamping mechanism 3 slides elastically on the mounting seat 2.

[0038] The present application provides a sky roller brake device for fabric printing and dyeing, in which the brake member 1 is connected to one end of the sky roller 4, and the brake member 1 is clamped by the clamping mechanism 3 to limit the rotation of the brake member 1, thereby limiting the rotation of the sky roller 4. At the same time, the clamping mechanism 3 is elastically slidably connected to the mounting seat 2. When the sky roller 4 is restricted from rotating, the fabric can be transported forward a short distance under the action of inertia to prevent the surface quality of the fabric from being affected by friction when the sky roller 4 stops suddenly. When the clamping mechanism 3 slides to the limit position, the sky roller 4 rotates under the action of elasticity, driven by the brake member 1, so that the fabric moves back a short distance to prevent the fabric before the sky roller 4 from being over-tensioned.

[0039] In some optional embodiments, the clamping mechanism 3 may specifically include a clamping seat 31, a first clamping arm 32, a second clamping arm 33 and a driving member 34; the clamping seat 31 is elastically slidably connected to the mounting seat 2, so that the clamping seat 31 can perform elastic sliding movement on the mounting seat 2, that is, the clamping seat 31 can slide on the mounting seat 2 in a specific direction under the condition of being driven by an external force, and when the clamping seat 31 slides to an extreme position in this direction, the clamping seat 31 can slide back to its original position in the direction opposite to the specific direction under the action of elasticity; the first clamping arm 32 is elastically rotatably connected to the clamping seat 31, so that at least one end of the first clamping arm 32 can swing on the clamping seat 31. In actual implementation, the first clamping arm 32 is a long plate structure, and the middle position of the first clamping arm 32 can be rotatably connected to the clamping seat 31 by a pin shaft, the axis of the pin shaft is parallel to the plate surface of the first clamping arm 32, and a torsion spring is also connected between the first clamping arm 32 and the pin shaft to achieve elastic rotation, that is, the torsion spring is sleeved on the pin shaft, When the second clamping arm 33 is in the state of being rotated, the second clamping arm 33 and the second clamping arm 33 are in the state of being rotated.

[0040] In some optional embodiments, the driving member 34 can be configured as an electromagnet, wherein the first clamping arm 32 and the second clamping arm 33 are respectively provided with a first attraction portion 35 and a second attraction portion 36 for attracting the driving member 34; in actual implementation, the driving member 34 is fixedly connected to the clamping seat 31 and is located between the first clamping arm 32 and the second clamping arm 33. After the driving member 34 is controlled to move, it simultaneously attracts the first clamping arm 32 and the second clamping arm 33 to make the first clamping arm 32 and the second clamping arm 33 rotate synchronously.

[0041] In some optional embodiments, an arc-shaped groove 21 is constructed on the mounting seat 2. After the mounting seat 2 is installed on the bracket, the center of the arc-shaped groove 21 is located on the axis of the sky roller 4, and a slider adapted to the arc-shaped groove 21 is provided on the clamping seat 31; thus, after the clamping mechanism 3 clamps the brake member 1, due to the inertia of the fabric, the brake member 1 will drive the clamping seat 31 to slide elastically on the mounting seat 2 along the extension direction of the arc-shaped groove 21.

[0042] In some optional embodiments, a plurality of steel balls are provided on the slider by a groove locking ball process, so as to improve the sliding smoothness of the clamping seat 31 on the mounting seat 2.

[0043] In some optional embodiments, a first arc spring 23 is connected to one end of the slider and the arc groove 21; wherein, the shape of the first arc spring 23 is adapted to the length direction of the arc groove 21, so that during the deformation of the first arc spring 23, the arc groove 21 can form a certain restriction on the first arc spring 23, preventing the first arc spring 23 from being folded in half, thereby ensuring that the direction of the elastic force is correct.

[0044] In some optional embodiments, a second arc spring 24 is connected to the other end of the slider and the arcuate slot 21. The shape of the second arc spring 24 matches the length of the arcuate slot 21. Thus, during deformation, the arcuate slot 21 can restrict the second arc spring 24, preventing it from facing each other and ensuring the correct direction of the elastic force. The provision of the first arc spring 23 and the second arc spring 24 can accelerate the slider's return to its original position, reducing the number of times the slider repeatedly slides in its original position and allowing the top roller 4 to quickly remain stationary.

[0045] In some optional embodiments, the brake member 1 is configured as a disc, and the brake member 1 is coaxially connected to the top roller 4. The regular shape of the disc can facilitate the clamping mechanism 3 to clamp the brake member 1 at any circumferential angle.

[0046] In some optional embodiments, friction plates are attached to the two disc surfaces of the brake member 1. This arrangement can prevent the brake member 1 from slipping with the first clamping arm 32 or the second clamping arm 33 when the clamping mechanism 3 clamps the brake member 1.

[0047] In some optional embodiments, the mounting base 2 is provided with a strip hole 22, and a connecting bolt for connecting to the printing and dyeing equipment bracket is configured in the strip hole 22. This arrangement can adjust the installation position of the mounting base 2 to a certain extent, thereby improving the installation flexibility of the brake device.
