Description

Technical Field

[0001] This utility model belongs to the field of spinning machinery, and specifically relates to a rotor brake device for a rotor spinning machine. Background Technology

[0002] Rotor spinning machines typically have rotors. When spinning using a rotor spinning machine, the high-speed rotation of the rotor causes the fibers to be twisted and drawn into yarn within the condensation groove of the rotor. The yarn is then drawn out continuously and wound into cones. When a yarn breakage occurs, the spinning machine must be turned on, and after the rotor stops rotating, the residual fibers inside the rotor must be cleaned. This is a crucial procedure to ensure successful splicing.

[0003] The rotor braking device on existing rotor spinning machines requires manual engagement of the brake block against the rotor. This not only results in slow braking speed but also lacks a limiting mechanism between the brake block and the rotor, posing a safety hazard. Furthermore, the slow braking speed causes dust from fibers or slivers inside the rotor to easily accumulate, making cleaning difficult. Moreover, since there is no limiting mechanism between the brake block and the rotor rod when the rotor is in a tilted, non-working position, the brake block can easily separate from the rotor rod, potentially damaging the rotor shaft and creating a safety hazard when workers clean residual fibers from inside the rotor. Utility Model Content

[0004] The purpose of this invention is to provide a rotor braking device for a rotor spinning machine, which can limit the brake block and prevent the brake block from separating from the rotor during the rotor braking process.

[0005] The technical solution of this utility model is as follows: a rotor brake device for a rotor spinning machine, which is located below the rotor seat of the rotor spinning machine. The rotor seat contains a rotor, and the rotor includes an integrally formed rotating shaft and a cup body. The rotating shaft is located in the middle of one side of the cup body. The rotor seat includes an integrally formed rotor seat body and two mounting plates. The rotor seat body is located outside the cup body of the rotor. A rotor bearing is provided between the rotor seat body and the cup body. The two mounting plates are symmetrically arranged on the rotor seat body, and both mounting plates are located below the rotating shaft of the rotor. The rotor brake device includes a brake mounting base and a brake block.

[0006] The brake mounting base is connected to the rotor seat and is located between the two mounting plates. The brake mounting base includes an integrally formed brake part, a rotating part, and an abutment part. The brake part is located below the rotor's rotation axis and has a mounting groove. The rotating part is located between the brake part and the abutment part and is rotatably connected to the mounting plate of the rotor seat. The abutment part is located below the rotor seat body and has a connecting groove on its upper part. A compression spring is provided in the connecting groove, and the top of the compression spring is connected to the rotor seat body of the rotor seat. One end of the lower surface of the abutment part has an abutment protrusion that abuts against the frame of the rotor spinning machine.

[0007] The brake block is located in the mounting groove of the brake part in the brake mounting seat, and the brake block and the brake mounting seat are connected to form an integral unit. The brake block is located below the rotating shaft of the rotating cup.

[0008] Furthermore, the side wall of the main body of the rotating cup holder is provided with a groove, and a support rod is provided in the connecting groove of the abutment part. The compression spring in the connecting groove is sleeved on the outside of the support rod, and the top end of the compression spring is located in the groove opened on the main body of the rotating cup holder.

[0009] Furthermore, the compression spring is always in a compressed state.

[0010] Furthermore, both mounting plates are provided with mounting holes, and a connecting hole is provided through the rotating part between the two mounting plates. The rotating part is rotatably connected to the two mounting plates through a pin, the connecting hole, and the mounting hole.

[0011] Furthermore, the upper surface of the brake block is arc-shaped, and the upper surface of the brake block is completely in contact with the rotating shaft.

[0012] The beneficial effects of this utility model are as follows: By rotating and pulling out the rotating cup seat around its connection with the frame, the rotating cup seat and the rotating cup are in an inclined state. At this time, the abutment protrusion below the abutment part in the brake mounting seat separates from the frame, and the compression spring extends, ensuring that the brake mounting seat can rotate under the elastic force of the compression spring. The compression spring causes the abutment part of the brake mounting seat to rotate downward around the connection between the rotating part and the mounting plate, while the brake part rotates upward around the connection between the rotating part and the mounting plate. When the brake part rotates upward, it drives the brake block set on it to move upward, pressing the brake block against the rotating shaft of the rotating cup, thereby achieving braking of the rotating cup. The elastic force of the compression spring presses the brake block against the rotating shaft, achieving rapid braking of the rotating cup and preventing the fiber material inside the rotating cup from agglomerating. At the same time, since the compression spring is always in a compressed state, it limits the brake block and prevents the brake block from separating from the rotating shaft of the rotating cup. This not only prevents damage to the rotating shaft but also avoids safety hazards to the workers. Attached Figure Description

[0020] The manual rotor braking device, where the brake block is pressed against the rotor, not only has a slow braking speed, but also causes dust from the fibers or cotton slivers inside the rotor to easily accumulate and be difficult to clean. Furthermore, because there is no limiting mechanism between the brake block and the rotor, the brake block can easily separate from the rotor rod, potentially damaging the rotor shaft and posing a safety hazard when workers clean residual fibers inside the rotor. Therefore, the inventors of this application provide a rotor braking device for a rotor spinning machine that can limit the brake block and prevent it from separating from the rotor during braking.

[0021] like Figure 1-4As shown, a rotor braking device for a rotor spinning machine is located below the rotor seat 1 of the rotor spinning machine. The rotor seat 1 contains a rotor 2, which includes an integrally formed rotating shaft 22 and a cup body 21. The rotating shaft 22 is located in the middle of one side of the cup body 21. The rotor seat 1 includes an integrally formed rotor seat body 11 and two mounting plates 12. The rotor seat body 11 is located outside the cup body 21 of the rotor 2. A rotor bearing is provided between the rotor seat body 11 and the cup body 21. The two mounting plates 12 are symmetrically arranged on the rotor seat body 11, and both mounting plates 12 are located below the rotating shaft 22 of the rotor 2. The rotor braking device includes a brake mounting base 3 and a brake block 4.

[0022] In this embodiment, the brake mounting base 3 is connected to the rotor seat 1, and the brake mounting base 3 is located between two mounting plates 12. The brake mounting base 3 includes an integrally formed brake part 31, a rotating part 32, and an abutment part 33. The brake part 31 is located below the rotating shaft 22 of the rotor 2, and the brake part 31 is provided with a mounting groove 31-1. The rotating part 32 is located between the brake part 31 and the abutment part 33, and the rotating part 32 is rotatably connected to the mounting plate 12 of the rotor seat 1. The abutment part 33 is located below the rotor seat body 11, and a connecting groove 33-1 is provided above the abutment part 33. A compression spring 34 is provided in the connecting groove 33-1, and the top end of the compression spring 34 is connected to the rotor seat body 11 of the rotor seat 1. An abutment protrusion 35 is provided at one end of the lower surface of the abutment part 33, and the abutment protrusion 35 abuts against the frame 5 of the rotor spinning machine.

[0023] The main body 11 of the rotating cup holder has a groove 11-1 on its side wall. A support rod 36 is provided in the connecting groove 33-1 of the abutment part 33. A compression spring 34 in the connecting groove 33-1 is sleeved on the outside of the support rod 36. The top of the compression spring 34 is located in the groove 11-1 on the main body 11 of the rotating cup holder. The compression spring 34 is always in a compressed state.

[0024] Based on the above embodiments, when the rotor 2 inside the rotor holder 1 is in working condition, the rotor holder 1 is placed on the frame 5 of the rotor spinning machine. At this time, the abutment part 33 of the brake mounting seat 3 abuts against the frame 5 through the abutment protrusion 35 below it, causing the compression spring 34 to be unable to extend. When it is necessary to clean the rotor 2, the rotor holder 1 is rotated and pulled out around its connection with the frame 5, so that the rotor holder 1 and the rotor 2 are in an inclined state. At this time, the abutment protrusion 35 below the abutment part 33 in the brake mounting seat 3 separates from the frame 5, and the compression spring 34 extends, ensuring that the brake mounting seat 3 rotates under the elastic force of the compression spring 34.

[0025] In this embodiment, each of the two mounting plates 12 is provided with a mounting hole 12-1, and the rotating part 32 between the two mounting plates 12 is provided with a connecting hole 32-1. The rotating part 32 is rotatably connected to the two mounting plates 12 through a pin, the connecting hole 32-1 and the mounting hole 12-1.

[0026] Based on the above embodiments, when the abutting part 33 of the brake mounting seat 3 is pressed downward by the compression spring 34, the rotating part 32 of the brake mounting seat 3 rotates around the pin that connects it to the mounting plate 12, and at this time the brake part 31 of the brake mounting seat 3 rotates upward.

[0027] In this embodiment, as Figure 1 , Figure 4 As shown, the brake block 4 is located in the mounting groove 31-1 of the brake part 31 in the brake mounting seat 3, and the brake block 4 is integrated with the brake mounting seat 3 after being connected. The brake block 4 is located below the rotating shaft 22 of the rotating cup 2.

[0028] Among them, such as Figure 1 , Figure 2 As shown, the upper surface of the brake block 4 is arc-shaped, and the upper surface of the brake block 4 is completely in contact with the rotating shaft 22.

[0029] Based on the above embodiments, the brake block 4 is made of wear-resistant material. When the compression spring 34 pushes the brake part 31 of the brake mounting seat 3 to rotate upward, the brake part 31 drives the brake block 4 to move upward, so that the brake block 4 is in contact with the rotating shaft 22 of the rotating cup 2. Since the compression spring 34 is always in a compressed state, it can press the brake block 4 against the rotating shaft 22.

[0030] The working principle of this utility model is as follows: When it is necessary to clean the rotating cup 2, the rotating cup seat 1 is rotated and pulled out around its connection with the frame 5, so that the rotating cup seat 1 and the rotating cup 2 are in an inclined state. At this time, the abutting protrusion 35 below the abutting part 33 in the brake mounting seat 3 separates from the frame 5, the compression spring 34 extends, ensuring that the brake mounting seat 3 rotates under the elastic force of the compression spring 34. The abutting part 33 of the brake mounting seat 3 rotates downward around the connection between the rotating part 32 and the mounting plate 12, while the brake part 31 rotates upward around the connection between the rotating part 32 and the mounting plate 12. When 31 rotates upward, it drives the brake block 4 mounted on it to move upward, pressing the brake block 4 against the rotating shaft 22 of the rotating cup 2, thereby braking the rotating cup 2. The elastic force of the compression spring 34 presses the brake block 4 against the rotating shaft 22, which can achieve rapid braking of the rotating cup 2 and prevent the fiber material inside the rotating cup 2 from agglomerating. At the same time, since the compression spring 34 is always in a compressed state, it limits the brake block 4 and prevents the brake block 4 from separating from the rotating shaft 22 of the rotating cup 2. This not only prevents damage to the rotating cup shaft, but also avoids safety hazards to the staff.

[0031] After the rotor 2 is cleaned, the rotor seat 1 is rotated back to its original position around the connection point with the frame 5. The rotor seat 1 is gradually placed on the frame 5 of the rotor spinning machine. During this process, the compression spring 34 is gradually compressed until the abutment part 33 of the brake mounting seat 3 abuts against the frame 5 through the abutment protrusion 35 below it, causing the compression spring 34 to be unable to extend. At the same time, the brake part 31 of the brake mounting seat 3 rotates downward around the connection point between the rotating part 32 and the mounting plate 12, driving the brake block 4 to move downward, so that the brake block 4 separates from the rotating shaft 22 of the rotor 2, ensuring that the rotor 2 can continue to rotate.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
