High-voltage electromagnetic wire enameling machine

Abstract

The present invention relates to the technical field of electromagnetic wire processing, and discloses a high-voltage electromagnetic wire enameling machine, which solves the problem that the wire control mechanism of a conventional electromagnetic wire enameling machine lacks limit. When adjusting it, the roller is easily pushed and moved under the action of the original tension of the longitudinal wire on one side of it, resulting in deviation and causing the eccentricity of the applied paint film to increase. By driving the moving component to rotate unidirectionally with a worm, the purpose of moving the assembly housing to adjust the position of the roller body is achieved. And it is inconvenient for the moving component to drive the worm in the reverse direction. When the worm does not move, the moving component will be limited in the current position, further fixing the position of the assembly housing. It ensures that when the original tension of the electromagnetic wire acts on the side of the roller body, it will not drive the assembly housing to move. And the further limitation of the worm by the braking component makes the worm not swing under normal conditions, avoiding the situation that the state of the moving component is not fixed enough and the roller body shakes.

Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic wire processing, specifically a high-voltage electromagnetic wire enameling machine. Background Art

[0002] An electromagnetic wire consists of a bare wire and an insulating paint film coated on the outside of it. It is divided into enameled round wire and enameled flat wire. Enameled flat wire is generally produced by a vertical enameling machine. Enameled flat wire is often used in the field of new energy vehicles. With the improvement of the enameled flat wire processing technology, there are more and more passes for painting and drying. Referring to the attached Figure 1 , the vertical enameling machine for processing enameled flat wire includes two upper and lower guide wheels, a painting mechanism, a drying mechanism, and a wire control mechanism. The enameled flat wire is wound between the two guide wheels in multiple turns and moves as the guide wheels rotate. It is painted and dried multiple times through the painting mechanism and the drying mechanism. Among them, in order to limit the enameled flat wire to pass through the painting mechanism and the drying mechanism along a suitable path and tension, and ensure the eccentricity of the paint film, a wire control mechanism is required to tension multiple coils between the two guide wheels;

[0003] Referring to the attached Figure 2 , the existing wire control mechanism includes a cross frame. There are multiple rollers on one side of the cross frame. The multiple rollers are correspondingly attached to the sides of multiple longitudinal lines of the enameled flat wire to restrict the positions of the longitudinal lines. The roller shafts are fixedly connected to the cross frame through movable blocks and nuts on one side. When there is a deviation in the movement path of the enameled flat wire, the nut needs to be loosened in time, and the position of the movable block is adjusted to move the position of the roller, so as to limit the enameled flat wire to a suitable movement path. In actual operation, due to the compact volume of the device, the spacing between multiple rollers is close, and the adjustment space of the movable block is small and there is no limit. When adjusting it, often after loosening the nut, the roller is easily pushed to move under the action of the original tension of the longitudinal line attached to one side of it, which is likely to cause a greater deviation of the longitudinal line attached to this roller in the direction of the tension, resulting in a greater error, causing the eccentricity of the paint film coated on this turn of the enameled flat wire to become larger, and causing the paint films coated subsequently to have an eccentric situation. In addition, the tension of the adjacent coils to this turn of the enameled flat wire will also be affected, resulting in the tension becoming loose, which is likely to cause the eccentricity of the paint film coated on this adjacent coil to become larger. The eccentricity of the paint film is measured in "nanometers", and a slight deviation will cause defective products of the enameled wire.

[0004] The existing patent number "CN114038624A" discloses "a wire control device and method for an enameled flat wire production device", including: when adjusting the position of the wire control wheel, only a wrench is used to loosen the bolt, and the adjustment space radius is the length of the swing arm, which is very convenient for adjusting the wire control wheel; in this embodiment, the swing arm is also fixed by bolts. When the bolts are loosened, the force arm of the swing arm is longer, and the above problems will be more common;

[0005] Therefore, in order to solve the problem of limiting the adjustment of the movable block in a small space, corresponding limiting measures need to be designed. Summary of the Invention

[0006] The object of the present invention is to provide a high-voltage electromagnetic wire enameling machine, which solves the problem that the wire control mechanism of the conventional electromagnetic wire enameling machine lacks limit. When adjusting it, the roller is easily pushed to move under the action of the original tension of the longitudinal wire on one side of it, resulting in deviation and causing the eccentricity of the coated paint film to become larger.

[0007] To achieve the above object, the present invention provides the following technical solution: a high-voltage electromagnetic wire enameling machine, including a wire control mechanism and two guide wheels around which multiple turns of electromagnetic wire are wound. The wire control mechanism includes an assembly frame, a roller body, and a traveling mechanism. The traveling mechanism is restricted to move on the surface of the assembly frame, and the roller body is installed on one side of the traveling mechanism and is attached to the side of the electromagnetic wire.

[0008] A moving groove is formed on the surface of the assembly frame. A threaded rod and a limiting rod are horizontally and fixedly assembled in the moving groove, and an external thread is provided on the outer surface of the threaded rod.

[0009] The traveling mechanism includes an assembly housing sleeved on the surfaces of the threaded rod and the limiting rod. The roller body is assembled on one side of the assembly housing. A moving component sleeved on the surface of the threaded rod and movable is assembled in the assembly housing. An internal thread matching the external thread on the surface of the threaded rod is provided in the moving component. The moving component drives the assembly housing to move on the surface of the assembly frame. A worm for driving the moving component to rotate unidirectionally is provided on the upper side of the threaded rod. A spiral groove matching the worm is formed on the outer surface of the moving component. A gear transmission component for driving the worm to rotate is provided on one side of the worm, and a braking component for braking the worm is provided. A control component for synchronously controlling the braking component and the gear transmission component is provided on one side of the braking component and the gear transmission component. Under normal conditions, the braking component limits the rotation of the worm.

[0010] As a further description of the above technical solution: The moving component includes a threaded sleeve. The internal thread is formed on the inner side of the threaded sleeve, and the spiral groove is formed on the outer surface of the threaded sleeve. A bearing is also assembled on the outer surface of the threaded sleeve. The outer ring of the bearing is fixedly connected to the inner wall of the assembly housing. The threaded sleeve is sleeved on the surface of the threaded rod and has a certain length.

[0011] As a further description of the above technical solution: The gear transmission component includes a first driving gear, a second driven gear, a third driven gear, and a fourth driven gear. The first driving gear is coaxially and fixedly connected to the control component, and the fourth driven gear is coaxially and fixedly connected to the worm. The second driven gear and the third driven gear are engaged between the first driving gear and the fourth driven gear to increase or decrease the transmission torque.

[0012] As a further description of the above technical solution: The braking assembly includes a parking brake release component assembled on one side of the first driving gear, a first disc brake component assembled on one side of the worm, and a second push brake component assembled on one side of the limit rod for damping the assembly housing in the opposite direction of movement.

[0013] As a further description of the above technical solution: The parking brake release component includes a mounting bracket, which is fixedly assembled on one side of the first driving gear without contact. A third brake cable and a second brake cable are assembled on the upper side of the mounting bracket. The second brake cable is connected to the first disc brake component, and the third brake cable is connected to the second push brake component. A cooperation block is slidably assembled inside the mounting bracket. One end of the steel wire inside the second brake cable and the third brake cable passes through the surface of the mounting bracket and is fixedly connected to the upper surface of the cooperation block. A first brake cable for pulling it is connected to the lower surface of the cooperation block. The steel wire inside the first brake cable is connected to the control component, and the control component pulls the first brake cable to make the cooperation block pull the second brake cable and the third brake cable simultaneously.

[0014] The first disc brake component includes a brake disc, which is coaxially fixedly assembled on one side of the worm. A brake shoe is sleeved on the edge of the brake disc. The brake shoe is fixedly assembled on the inner wall of the assembly housing. A brake pad is arranged inside the brake shoe and is in movable frictional contact with the surface of the brake disc. A fixed bracket and a movable bracket are fixedly installed on the outer surface of the brake shoe. One end of the movable bracket passes through the brake shoe and is fixedly connected to the surface of the brake pad. A push spring A is arranged between the fixed bracket and the movable bracket. In the normal state, the push spring A pushes the movable bracket to make the brake pad closely adhere to the surface of the brake disc. One end of the second brake cable is fixed on the surface of the fixed bracket, and its inner steel wire passes through the fixed bracket and is fixedly connected to the side surface of the movable bracket.

[0015] As a further description of the above technical solution: The second push brake component includes a deflection and push part. One end of the deflection and push part is movably connected with a friction rubber pad. The friction rubber pad is elastically pushed by the deflection and push part to be in movable contact with the side surface of the limit rod for frictional contact. One end of the third brake cable is connected to one side of the deflection and push part for pulling to make the friction rubber pad separate from the surface of the limit rod. The middle part of the deflection and push part is rotatably installed on a partition inside the assembly housing. A deflection groove for rotatably installing the deflection and push part is opened on the partition. The deflection and push part rotates freely at a preset angle inside the deflection groove. A first contact pad is fixedly arranged on the lower surface of the deflection and push part facing the fourth driven gear. A sector gear is meshed and connected to the upper side of the fourth driven gear. A second contact pad for frictional contact with the first contact pad is fixedly arranged on the upper side of the sector gear. When the worm drives the moving component to make the assembly housing move in one direction, the fourth driven gear drives the deflection and push part through the sector gear, so that the friction rubber pad deflects in the moving direction.

[0016] As a further description of the above technical solution: The deflection driving part includes a sleeve, which is rotatably installed inside the deflection groove. An extrusion rod that linearly moves is arranged inside the sleeve. The outer end of the extrusion rod is rotatably connected to a friction rubber pad. A push spring B that elastically pushes the extrusion rod outward is arranged inside the sleeve. One end of the third brake wire is fixedly connected to one side of the sleeve, and the steel wire inside the third brake wire passes through the sleeve and is fixedly connected to one end of the extrusion rod.

[0017] As a further description of the above technical solution: The control assembly includes a swing rod and a support frustum. The support frustum is coaxially and fixedly connected to one side of the first driving gear. A side stopper is arranged on one side of the support frustum to movably assemble the swing rod. A cylindrical pull bolt axially penetrates through the support frustum. The cylindrical pull bolt axially penetrates to the side surface of the first driving gear and is fixedly connected to one end of the steel wire inside the first brake wire. The other end of the cylindrical pull bolt penetrates to the side surface of the support frustum and is rotatably connected to the swing rod. A pull rod is arranged inside the swing rod and is rotatably connected to the cylindrical pull bolt. An arc-shaped part is arranged on the swing rod close to the support frustum.

[0018] As a further description of the above technical solution: The cylindrical pull bolt includes a first pull column and a second pull column that are rotatably connected. The first pull column is rotatably connected to the swing rod. One end of the second pull column protrudes from the surface of the first driving gear. A limiting part is arranged on the side surface of the second pull column. A limiting sleeve for the limiting part to movably embed is fixedly installed on one side of the mounting frame. The limiting sleeve restricts the rotation of the limiting part.

[0019] As a further description of the above technical solution: A rocker is clamped on one side of the swing rod, and a clamping groove corresponding to the rocker is arranged on one side of the swing rod.

[0020] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: The worm drives the moving component to rotate unidirectionally, achieving the purpose of adjusting the position of the roller body by moving the assembly housing. Since the moving component is not convenient to drive the worm in the reverse direction, when the worm is stationary, the moving component will be limited to the current position, further fixing the position of the assembly housing. This ensures that when the original tension of the electromagnetic wire acts on the side of the roller body, the assembly housing will not be driven to move; the braking component further limits the worm, so that under normal conditions, the worm will not swing, avoiding the situation where the state of the moving component is not fixed enough and the roller body shakes; regarding the control component, before driving the gear transmission component to rotate and driving the worm to rotate, it will drive the braking component to release the limit on the worm. During the transformation of the worm from the fixed state to the movable state, the worm is always under force control without a vacuum period, further ensuring that when the position of the assembly housing needs to be adjusted, the state of the assembly housing is always under force control and will not undergo uncontrolled movement, ensuring the accuracy of adjusting the position of the roller body; finally, the internal thread can achieve directional limitation of the assembly housing. There is a component of the thrust along the axial direction of the limiting rod opposite to the moving direction of the assembly housing, ensuring that the moving component remains in extrusion contact with the threaded rod in the original state, thus avoiding the displacement shaking caused by the extremely small gap between the thread teeth, and further ensuring the fixed position of the roller body.

Detailed implementation mode

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0043] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings.

[0044] Combined with Figures 1 - 17 , the high-voltage electromagnetic wire enameling machine includes a wire control mechanism 10 and two guide wheels wound with multiple turns of electromagnetic wire. The wire control mechanism 10 includes an assembly frame 20, a roller body 30, and a traveling mechanism 40. The traveling mechanism 40 is restricted to move on the surface of the assembly frame 20. The roller body 30 is installed on one side of the traveling mechanism 40 and fits against the side of the electromagnetic wire to limit the electromagnetic wire.

[0045] A moving groove is provided on the surface of the assembly frame 20, and a threaded rod 21 and a limit rod 22 are horizontally and fixedly assembled in the moving groove. An external thread is provided on the outer surface of the threaded rod 21.

[0046] The traveling mechanism 40 includes an assembly housing 41 sleeved on the surfaces of the threaded rod 21 and the limiting rod 22. There is no restriction on the external shape of the assembly housing 41. The roller body 30 is assembled on one side of the assembly housing 41. A moving component 42 sleeved on the surface of the threaded rod 21 and movable is assembled in the assembly housing 41. The limiting rod 22 limits one side of the assembly housing 41, so that the assembly housing 41 linearly moves on the surface of the assembly frame 20. An internal thread 423 that mates with the external thread on the surface of the threaded rod 21 is provided in the moving component 42. By rotating the moving component 42, the internal thread 423 is made to mate with the external thread on the surface of the threaded rod 21, pushing the assembly housing 41 to move on the surface of the assembly frame 20, achieving the purpose of driving the assembly housing 41 to move on the surface of the assembly frame 20 by the moving component 42. A worm 43 for driving the moving component 42 to rotate unidirectionally is provided above the threaded rod 21. A worm groove 424 that mates with the worm 43 is formed on the outer surface of the moving component 42. The rotation of the worm 43 drives the moving component 42 to rotate, and the moving component 42 cannot drive the worm 43 to rotate in the reverse direction. In this way, the worm 43 is used to drive the moving component 42 to rotate unidirectionally, achieving the purpose of moving the assembly housing 41 and adjusting the position of the roller body 30. Since the moving component 42 is inconvenient to drive the worm 43 to rotate in the reverse direction, when the worm 43 does not move, the moving component 42 will be limited in the current position, further fixing the position of the assembly housing 41. This ensures that when the original tension of the electromagnetic wire acts on the side of the roller body 30, it will not drive the assembly housing 41 to move, thus solving the problem that the wire control mechanism lacks limitation. When adjusting it, the roller is easily pushed to move under the action of the original tension of the longitudinal wire attached to one side of it, resulting in deviation and causing the eccentricity of the painted film to become larger.

[0047] A gear transmission component 45 for driving the worm 43 to rotate and a braking component 44 for braking it are provided on one side of the worm 43. A control component 46 for synchronously controlling them is provided on one side of the braking component 44 and the gear transmission component 45. Under normal conditions, the braking component 44 limits the rotation of the worm 43. By limiting the worm 43 through the braking component 44, the rotation of the worm 43 can be further limited, ensuring that the worm 43 will not swing within a small range under normal conditions, resulting in an insufficiently fixed state of the worm groove 424 under normal conditions and causing the roller body 30 to shake. Before the control component 46 drives the gear transmission component 45 to rotate and drive the worm 43 to rotate, it will drive the braking component 44 to release the limitation of the braking component 44 on the worm 43. During this process of changing the state of the worm 43 from a fixed state to an active state, the control component 46 is in a stressed state to control the worm 43. Therefore, the control of the rotation state of the worm 43 is transferred from the braking component 44 to the control component 46. During the process, there is no vacuum period for the rotational control of the worm 43, further ensuring that when the position of the assembly housing 41 needs to be adjusted, during the transition of the assembly housing 41 from a fixed state to an active state, it is always controlled and will not move uncontrollably, ensuring the accuracy of the position adjustment of the roller body 30.

[0048] Further, the roller body 30 is fixed to one side of the traveling mechanism 40 through a support rod 31. The roller bodies 30 on one side of two adjacent traveling mechanisms 40 are arranged one above the other through the support rod 31, so as to adjust the spacing between multiple roller bodies 30 in the same plane to be tight, so as to facilitate the repair and replacement operations of the roller bodies 30.

[0049] In the previous embodiment: The moving component 42 includes a threaded sleeve 422. An internal thread 423 is provided on the inner side of the threaded sleeve 422. A spiral groove 424 is provided on the outer surface of the threaded sleeve 422. A bearing 421 is also assembled on the outer surface of the threaded sleeve 422. The outer ring of the bearing 421 is fixedly connected to the inner wall of the assembly housing 41. The threaded sleeve 422 is sleeved on the surface of the threaded rod 21 and has a length such that there is sufficient contact area with the threaded rod 21 to form a more stable connection.

[0050] In the previous embodiment: The gear transmission component 45 includes a first driving gear 451, a second driven gear 452, a third driven gear 453, and a fourth driven gear 454. The first driving gear 451 and the control component 46 are coaxially and fixedly connected. The fourth driven gear 454 and the worm 43 are coaxially and fixedly connected. The second driven gear 452 and the third driven gear 453 are engaged between the first driving gear 451 and the fourth driven gear 454 to increase or decrease the transmission torque. According to the requirement of the rotation accuracy of the worm 43, the diameters and positions of the second driven gear 452 and the third driven gear 453 can be adaptively adjusted to change the torque of the first driving gear 451 driving the fourth driven gear 454 to rotate;

[0051] It should be noted that: The meshing relationship between the first driving gear 451, the second driven gear 452, the third driven gear 453, and the fourth driven gear 454 is set in advance during production according to the requirement of the rotation accuracy of the worm 43 in actual application. Here, the second driven gear 452 and the third driven gear 453 are engaged between the first driving gear 451 and the fourth driven gear 454 to increase or decrease the transmission torque, which is not limited.

[0052] In the previous embodiment: The braking assembly 44 includes a brake release component 441 assembled on one side of the first driving gear 451, and a first disc brake component 442 assembled on one side of the worm 43. The brake release component 441 includes a mounting bracket 4411 which is fixedly assembled on one side of the first driving gear 451 without contact. On the upper side of the mounting bracket 4411, a third brake cable 4416 and a second brake cable 4415 are assembled. The second brake cable 4415 is connected to the first disc brake component 442, and the third brake cable 4416 is connected to the second push brake component 443. A cooperation block 4414 is slidably assembled inside the mounting bracket 4411. One end of the steel wire inside the second brake cable 4415 and the third brake cable 4416 passes through the surface of the mounting bracket 4411 movably and is fixedly connected to the upper surface of the cooperation block 4414. A first brake cable 4412 for pulling it is connected to the lower surface of the cooperation block 4414. The steel wire inside the first brake cable 4412 is connected to the control assembly 46. The control assembly 46 pulls the first brake cable 4412, so that the cooperation block 4414 pulls the second brake cable 4415 and the third brake cable 4416 simultaneously, further achieving the purpose of controlling the first disc brake component 442 and the second push brake component 443 simultaneously;

[0053] The first disc brake component 442 includes a brake disc 4421 which is coaxially and fixedly assembled on one side of the worm 43. A brake shoe 4422 is sleeved on the edge of the brake disc 4421. The brake shoe 4422 is fixedly assembled on the inner wall of the assembly housing 41. A brake pad 4423 which is movably frictionally attached to the surface of the brake disc 4421 is arranged inside the brake shoe 4422. (As shown in the appendix Figure 14 figure) A fixed bracket 4424 fixedly installed and a movable bracket 4425 movably installed are arranged on the outer surface of the brake shoe 4422. One end of the movable bracket 4425 passes through the brake shoe 4422 movably and is fixedly connected to the surface of the brake pad 4423. A push spring A 4426 is arranged between the fixed bracket 4424 and the movable bracket 4425. In the normal state, the push spring A 4426 pushes the movable bracket 4425 to make the brake pad 4423 closely attached to the surface of the brake disc 4421, braking the brake disc 4421, and further achieving the purpose of braking the worm 43. One end of the second brake cable 4415 is fixed on the surface of the fixed bracket 4424. After its inner steel wire passes through the fixed bracket 4424 movably, it is fixedly connected to the side surface of the movable bracket 4425. When the steel wire pulls the movable bracket 4425, the brake pad 4423 will be separated from the frictional contact with the surface of the brake disc 4421, so that the worm 43 can rotate normally.

[0054] In the previous embodiment: in order to solve the structural relationship of the worm 43, the threaded sleeve 422 and the threaded rod 21 through threaded meshing, there is a very small gap between the threaded meshing teeth, which will also cause the assembly shell 41 to have a very small displacement shake, which makes the roller body 30 set on the enameling machine to limit the normal position of the enameled wire, causing a certain degree of displacement. In this embodiment, a second push brake component 443 for damping the assembly shell 41 in the opposite direction of movement is assembled on one side of the limit rod 22. The second push brake component 443 includes a deflection push part 4431, and one end of the deflection push part 4431 is movably connected to a friction rubber pad 4432. The friction rubber pad 4432 is elastically pushed by the deflection push part 4431 to fit the side surface of the limit rod 22 for friction contact. One end of the third brake line 4416 is connected to one side of the deflection push part 4431, and is used to pull the friction rubber pad 4432 away from the surface of the limit rod 22 (as shown in the attached Figure 8 , Attachment Figure 9 , Attachment Figure 15 , Attachment Figure 16 The deflection push part 4431 is rotatably mounted on a partition inside the assembly shell 41 in the middle part thereof, and a deflection groove 411 for rotatably mounting the deflection push part 4431 is provided on the partition. The deflection push part 4431 is freely rotatable at a preset angle inside the deflection groove 411, and a first contact pad 4433 is fixedly arranged on the lower surface of the deflection push part 4431 facing the fourth driven gear 454, and a sector gear 4435 is meshedly connected to the upper side of the fourth driven gear 454, and a third contact pad 4433 is fixedly arranged on the upper side of the sector gear 4435 with friction contact with the first contact pad 4433 The second contact pad 4434 can drive the sector gear 4435 to rotate when the fourth driven gear 454 rotates, so that the rotating second contact pad 4434 pushes the first contact pad 4433 through friction force, and further causes the rotatable deflection pusher 4431 to deflect to one side. When the worm 43 drives the moving assembly 42 to cause the assembly housing 41 to move in one direction, the fourth driven gear 454 drives the deflection pusher 4431 through the sector gear 4435, so that the friction rubber pad 4432 deflects in the moving direction;

[0055] In actual operation, when the threaded sleeve 422 rotates on the surface of the threaded rod 21, driving the assembly housing 41 to move, the inner thread 423 of the inner thread 423 is in contact with the outer thread of the threaded rod 21 on the side close to the moving direction (such as the attached Figure 17), so the threaded sleeve 422 has space to move in the moving direction on the surface of the threaded rod 21. In this embodiment, during the movement of the threaded sleeve 422, the third brake line 4416 pulls the friction rubber pad 4432 to separate from the surface of the limiting rod 22, that is, the friction rubber pad 4432 can be separated from the damping state of the limiting rod 22, and the deflection pusher 4431 can be freely rotated. Subsequently, the end of the deflection pusher 4431 with the friction rubber pad 4432 is automatically rotated to the side of the moving direction of the threaded sleeve 422 through the drive of the fourth driven gear 454. When the third brake line 4416 is released to pull the friction rubber After the rubber pad 4432 is moved, the friction rubber pad 4432 is elastically pushed by the deflection pushing part 4431, and the inclined friction rubber pad 4432 is in friction contact with the surface of the limit rod 22. While clamping and fixing, the thrust of the deflection pushing part 4431 on the friction rubber pad 4432 in the axial direction of the limit rod 22 will be opposite to the direction in which the threaded sleeve 422 moves. Therefore, the threaded sleeve 422 can be pushed to maintain the extrusion contact with the threaded rod 21 in the original state after the adjustment is completed, thereby avoiding the displacement and shaking caused by the extremely small gap between the threaded teeth, and further ensuring the fixed position of the roller body 30.

[0056] Furthermore, the deflection pushing portion 4431 includes a sleeve 44311, which is rotatably installed on the inner side of the deflection groove 411. A linearly movable extrusion rod 44312 is provided on the inner side of the sleeve 44311. The outer end of the extrusion rod 44312 is rotatably connected to the friction rubber pad 4432, which ensures that the friction rubber pad 4432 can still fully contact the surface of the limit rod 22 after the extrusion rod 44312 is rotated by an angle. A push spring B44313 is provided on the inner side of the sleeve 44311 for elastically pushing the extrusion rod 44312 outward. One end of the third brake line 4416 is fixedly connected to one side of the sleeve 44311, and the inner steel wire of the third brake line 4416 passes through the sleeve 44311 and is fixedly connected to one end of the extrusion rod 44312.

[0057] In the previous embodiment: the control component 46 includes a swing rod 461 and a support truncated plate 462. The support truncated plate 462 is coaxially fixedly connected to one side of the first driving gear 451. A side block 4621 is provided on one side of the support truncated plate 462 to movably assemble the swing rod 461. The swing rod 461 and the support truncated plate 462 can rotate coaxially. A cylindrical pull bolt 463 is movably penetrated through the axis of the support truncated plate 462. The cylindrical pull bolt 463 movably penetrates the side surface of the first driving gear 451 and is fixedly connected to one end of the inner steel wire of the first brake line 4412. The other end of the cylindrical pull bolt 463 penetrates the side surface of the support truncated plate 462 and is rotatably connected to the swing rod 461. A pull rod 4613 is provided on the inner side of the swing rod 461 and is rotatably connected to the cylindrical pull bolt 463. The swing rod 461 is provided with an arc portion 4612 on the side close to the support truncated plate 462. (As shown in the attached Figure 11 , AttachmentFigure 13 As shown in the figure, when the swing rod 461 is rotated to be coaxial with the support frustum 462 through the arc portion 4612, it will pull the cylindrical bolt 463 outward, further prompting the first brake wire 4412 to be pulled, so that the second brake wire 4415 and the third brake wire 4416 respectively pull the first disc brake component 442 and the second push brake component 443 to disconnect the braking state of the assembly housing 41. When the swing rod 461 is rotated to be perpendicular to the rotation axis of the support frustum 462, the cylindrical bolt 463 moves back to its original position and no longer pulls the first brake wire 4412, thereby prompting the first disc brake component 442 and the second push brake component 443 to resume the braking state of the assembly housing 41.

[0058] In the previous embodiment: The cylindrical bolt 463 includes a first pull column 4631 and a second pull column 4632 which are rotatably connected. The first pull column 4631 is rotatably connected to the swing rod 461. One end of the second pull column 4632 protrudes from the surface of the first driving gear 451. A limiting portion 4633 is provided on the side surface of the second pull column 4632. A limiting sleeve 4413 for the limiting portion 4633 to be movably embedded is fixedly installed on one side of the mounting bracket 4411. The limiting sleeve 4413 restricts the rotation of the limiting portion 4633. When the swing rod 461 is adjusted to be coaxial with the support frustum 462, the first driving gear 451 can be driven to rotate by rotating the swing rod 461, and then the worm 43 is driven to rotate in a linkage manner to adjust the position of the assembly housing 41. Since the first pull column 4631 and the second pull column 4632 are rotatably connected, and the limiting sleeve 4413 limits the rotation of the second pull column 4632, the second pull column 4632 does not rotate with the first driving gear 451, thereby ensuring the effective connection between the limiting portion 4633 and the first brake wire 4412.

[0059] In the previous embodiment: A rocker 47 is clamped on one side of the swing rod 461. A clamping groove 4611 corresponding to the rocker 47 is provided on one side of the swing rod 461. The rocker 47 can not only save effort to shake the control assembly 46 to drive the first driving gear 451 to rotate, but also increase the lever arm length of the control assembly 46 when the cylindrical bolt 463 is pulled out through the control assembly 46, so as to pull out the cylindrical bolt 463 with less effort.

[0060] Working principle: Assemble the rocker 47 onto the swing rod 461 perpendicular to the rotation axis of the support round table 462, and rotate the swing rod 461 to be coaxial with the support round table 462. Among them, the cylindrical pull bolt 463 will pull the first brake wire 4412 connected to one side, so that the cooperation block 4414 connected to the other end of the first brake wire 4412 will simultaneously pull the second brake wire 4415 and the second brake wire 4415. The second brake wire 4415 and the third brake wire 4416 respectively pull the first disc brake component 442 and the second push brake component 443 to disconnect the braking state of the assembly housing 41. Subsequently, shake the rocker 47 to cause the control assembly 46 to rotate, and further drive the worm 43 to rotate through the gear transmission assembly 45 connected to one side. The rotating worm 43 drives the moving assembly 42, so that the assembly housing 41 moves on the assembly frame 20, thereby achieving the purpose of adjusting the position of the roller body 30. During the rotation of the worm 43, the second push brake component 443 automatically turns to one side of the moving direction of the moving assembly 42. After the position of the moving assembly 42 is adjusted, restore the control assembly 46 to be perpendicular to the rotation axis of the support round table 462. Further, the first disc brake component 442 and the second push brake component 443 will also restore the braking state of the assembly housing 41. Among them, for the rotated second push brake component 443, the component force of the thrust of its deflection pushing part 4431 on the friction rubber pad 4432 in the axial direction along the limit rod 22 will be opposite to the moving direction of the threaded sleeve 422. Therefore, after the moving assembly 42 is adjusted by pushing, it can still maintain the extrusion contact with the threaded rod 21 in the original state.
