Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically a spindle braking device. Background Technology

[0002] Brushing is a process in the textile industry where yarn is brushed by a brushing machine, creating a layer of short nap on the yarn surface. This process retains the original characteristics of the yarn while adding a new style, and also provides strong warmth and softness, resulting in a lightweight texture that has won the favor of many people.

[0003] During the production process of a brushing machine, yarn breakage may occur. After a yarn breakage, manual operation is required to guide the yarn. However, the spindle cannot guide the yarn while rotating at high speed, which can easily injure the operator, seriously reduce production efficiency, and cause production accidents. The old-fashioned brake caliper is a single brake, which requires each spindle to be picked up and put back, making the operation cumbersome and reducing production efficiency.

[0004] Therefore, a spindle braking device is proposed to solve the above-mentioned problems in existing equipment. The spindle braking device can make the spindle stop stably, facilitate the operation of the operator to pull the wire, avoid worker injury, and improve production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spindle brake device that is simple to operate, safe and stable, and solves the problems of cumbersome operation and reduced production efficiency associated with old-style brake calipers.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spindle braking device, comprising a base plate and a grinding spindle rotatably connected to the top of the base plate, wherein the top of the base plate is provided with a braking assembly for decelerating and braking the grinding spindle, and the top of the base plate is provided with a control assembly for adjusting the braking assembly.

[0007] The brake assembly includes a brake caliper rotating shaft threaded to the top of the base plate. A brake caliper body plate is rotatably connected to the outer side of the brake caliper rotating shaft. A brake caliper bushing is rotatably connected to the top of the brake caliper body plate. A return spring for resetting is provided on the outer side of the brake caliper rotating shaft. A brake block is fixed to the top of the brake caliper body plate. A brake caliper paddle for use with the control assembly is fixed to the top of the brake caliper body plate. A brake caliper guide wheel is rotatably connected to the top of the brake caliper body plate.

[0008] Furthermore, the control component includes a handle base fixedly mounted on the top of the base plate, a handle rotating block rotatably connected to the top of the handle base, and a brake handle threadedly connected to the front of the handle rotating block.

[0009] Furthermore, the brake caliper body has an I-shaped structure, and a through hole is provided on the top left side of the brake caliper body for use with the brake caliper rotation shaft. The brake caliper bushing is nested on the outer side of the top of the brake caliper bushing.

[0010] Furthermore, the torsion spring has a Z-shaped structure, and the top of the base plate has several limiting holes for use with the torsion spring. The bottom of the torsion spring is vertically embedded in the limiting holes and fixedly installed with the base plate.

[0011] Furthermore, the brake caliper rotating shaft vertically passes through the inner cavity of the return spring and is slidably connected to the return spring, and a top rod that works in conjunction with the brake caliper body plate is fixed to the top of the return spring.

[0012] Furthermore, the brake block has a deceleration arc groove at one end near the grinding spindle for use with the grinding spindle, and two fixing slots at the top of the brake block for use with the brake caliper body plate.

[0013] Furthermore, the top of the base plate has several mounting holes for fixing to the handle base, and the right end of the brake caliper body extends to the lower left side of the handle base.

[0014] Furthermore, the brake caliper paddle is located on the top of the brake caliper body plate on the back of the handle rotating block, and the side of the handle rotating block near the brake caliper paddle has an arc surface for use with the brake caliper paddle.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] 1. The spindle braking device uses a control component to rotate a handle and squeeze a brake caliper paddle inside the brake assembly. This pushes the brake caliper body to squeeze the grinding spindle. The friction between the two causes the rotation of the grinding spindle to encounter greater resistance, reducing its rotation speed. Further squeezing increases the friction until the grinding spindle stops rotating smoothly under the action of friction, achieving a rapid stopping effect.

[0017] 2. The spindle braking device has a return spring installed on the outside of the brake caliper rotating shaft to hold the brake caliper body plate. When the brake caliper paddle at the top of the brake caliper body plate is not squeezed, the external force on the brake caliper body plate is only the return spring. Under the restoring force of the return spring, the brake caliper body plate is pushed back to the initial position, the brake block is separated from the grinding spindle, and the grinding spindle continues to rotate under the drive of the drive device, thus quickly restoring rotation.

[0023] 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.

[0024] Please see Figure 1 In this embodiment, a spindle braking device includes a base plate 1 and a grinding spindle 2 rotatably connected to the top of the base plate 1. The top of the base plate 1 is provided with a brake assembly 3 for decelerating and braking the grinding spindle 2, and the top of the base plate 1 is provided with a control assembly 4 for adjusting the brake assembly 3.

[0025] Please see Figures 2 to 3 The brake assembly 3 includes a brake caliper rotating shaft 31 threaded to the top of the base plate 1. A brake caliper body plate 32 is rotatably connected to the outside of the brake caliper rotating shaft 31. A brake caliper bushing 33 is rotatably connected to the top of the brake caliper body plate 32. A return spring 34 for resetting is provided on the outside of the brake caliper rotating shaft 31. A brake block 35 is fixed to the top of the brake caliper body plate 32. A brake caliper paddle 36 for use with the control assembly 4 is fixed to the top of the brake caliper body plate 32. A brake caliper guide wheel 37 is rotatably connected to the top of the brake caliper body plate 32.

[0026] In this embodiment, the brake caliper body plate 32 has an I-shaped structure, and a through hole is provided on the top left side of the brake caliper body plate 32 to cooperate with the brake caliper rotating shaft 31. The brake caliper bushing 33 is nested on the outer side of the top of the brake caliper bushing 33.

[0027] In this embodiment, the torsion spring 34 has a Z-shaped structure. The top of the base plate 1 has several limiting holes for use with the torsion spring 34. The bottom of the torsion spring 34 is vertically embedded in the limiting holes and fixedly installed with the base plate 1. The brake caliper rotating shaft 31 vertically passes through the inner cavity of the torsion spring 34 and is slidably connected with the torsion spring 34. The top of the torsion spring 34 is fixed with a push rod for use with the brake caliper body plate 32.

[0028] By setting a return spring 34 on the outside of the brake caliper rotating shaft 31 to abut against the brake caliper body plate 32, and simultaneously fixing the return spring 34 to the base plate 1, the brake caliper body plate 32 will be squeezed and deformed during rotation. When the brake caliper body plate 32 is not subjected to external force, it will be reset under the restoring force of the return spring 34.

[0029] In this embodiment, the brake block 35 has a deceleration arc groove at one end near the grinding spindle 2 for use with the grinding spindle 2, and two fixing slots are provided on the top of the brake block 35 for use with the brake caliper body plate 32.

[0030] By opening a deceleration groove on the side of the brake block 35 to abut against the side of the grinding spindle 2, the rotation of the grinding spindle 2 is decelerated, thereby achieving the effect of stopping the grinding spindle 2.

[0031] Please see Figure 4 In this embodiment, the control component 4 includes a handle base 41 fixedly installed on the top of the base plate 1. A handle rotating block 42 is rotatably connected to the top of the handle base 41, and a brake handle 43 is threadedly connected to the front of the handle rotating block 42.

[0032] In this embodiment, the top of the base plate 1 is provided with several mounting holes for fixing to the handle base 41, and the right end of the brake caliper body plate 32 extends to the lower left side of the handle base 41.

[0033] In this embodiment, the brake caliper paddle 36 is located on the top of the brake caliper body plate 32 on the back of the handle rotating block 42, and the side of the handle rotating block 42 near the brake caliper paddle 36 is provided with an arc surface that is used in conjunction with the brake caliper paddle 36.

[0034] Understandably, when the brake caliper paddle 36 is squeezed by the handle rotating block 42, it will push the brake caliper body 32 to rotate, thereby causing the brake block 35 to squeeze the grinding spindle 2, and the grinding spindle 2 will stop rotating under the action of friction.

[0035] The working principle of the above embodiments is as follows:

[0036] By rotating the brake handle 43, the handle rotating block 42 is pushed to rotate, which in turn squeezes the brake caliper paddle 36. The brake caliper paddle 36, under pressure, causes the brake caliper body 32 to rotate around the brake caliper rotating shaft 31. During the rotation, the brake caliper body 32 compresses the return spring 34 and contracts, while simultaneously pushing the brake block 35 closer to the grinding spindle 2, squeezing the grinding spindle 2. The friction generated after the grinding spindle 2 is squeezed stops its rotation, thus achieving stable braking. When the brake handle 43 is released, the brake caliper body 32 is pushed back to its initial position under the restoring force of the return spring 34, and the brake block 35 moves away from the grinding spindle 2, which continues to rotate. This solves the problem of cumbersome operation and reduced production efficiency of the old-style brake caliper.
