Description

Technical Field

[0001] The invention relates to the technical field of textile machinery, in particular to a roller disassembly device and a working method thereof. Background Art

[0002] In the field of textile machinery, rollers are a very critical component. In the textile process, the main function of rollers is to perform operations such as drafting the fibers. However, during long-term use, rollers may suffer from problems such as wear and deformation. For example, the surface of the roller body of the roller may be scratched or unevenly worn due to long-term contact with the fiber, which will affect the roller's drafting effect on the fiber. At this time, it is necessary to use a roller disassembly device to disassemble the roller from the textile machinery and perform maintenance on it, such as repairing the roller surface or replacing worn parts.

[0003] However, in many roller structures, the shaft and the roller are connected by interference fit. This means that the outer diameter of the shaft is slightly larger than the inner diameter of the roller. When the shaft is pressed into the roller, due to the size difference between the two, a large pressure is generated on the contact surface, making the two tightly combined, and it is difficult to separate the shaft from the roller. Therefore, a roller disassembly device and a working method thereof are proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a roller disassembly device and a working method thereof.

[0005] In order to solve the above-mentioned background technical problems, the present invention adopts the following technical solutions:

[0006] A roller disassembly device comprises a frame, a controller is arranged on the frame, a working groove is opened on the top of the frame, the working groove is used to accommodate the roller, the roller comprises a shaft body and a roller body, the roller body is sleeved on the shaft body, and the shaft body and the roller body are interference fit;

[0007] The left side of the frame is interspersed with an oil cylinder fixedly connected thereto, the oil cylinder extends into the working groove, and the output shaft of the oil cylinder is fixedly connected to a push rod;

[0008] A plurality of groups of latch holes are arranged on the frame and on the front and rear sides of the working slot, wherein a limit latch is inserted into one group of latch holes, a through hole is arranged on the limit latch, and the limit latch is sleeved on the shaft body through the through hole.

[0009] As a further solution of the present invention: the center of the through hole corresponds exactly to the axis of the push rod, and the limit latch is provided with an adjustment mechanism for keeping the shaft body and the through hole concentric.

[0010] As a further solution of the present invention: an accommodating groove is provided on the right side of the limiting latch and at the periphery of the through hole, and the adjusting mechanism is located in the accommodating groove.

[0011] As a further solution of the present invention: the adjustment mechanism includes two opposite arc plates, and elastic parts are provided on the opposite sides of the two arc plates. The two elastic parts are respectively connected to the limit latches, the arc plates and the elastic parts are both located in the accommodating grooves, and the opposite sides of the two arc plates are rotatably connected with a plurality of evenly distributed balls.

[0012] As a further solution of the present invention: the elastic member includes a shell, the shell is located in the accommodating groove and is fixed on the limit latch by bolts, a connecting rod is inserted into the shell, the connecting rod is fixedly connected to the arc plate, the arc plate is located at one end of the shell and is fixedly connected to a limit block, the limit block is fixedly connected to an end away from the connecting rod with a spring, and the spring is fixedly connected to the inner wall of the shell.

[0013] As a further solution of the present invention: the limit block is a polygonal structure and is in smooth contact with the inner wall of the shell.

[0014] A working method of a roller disassembly device comprises the following steps:

[0015] S1. Insert the limit latch into the latch hole so that the limit latch is mounted on the frame;

[0016] S2, inserting the shaft of the roller into the through hole of the limit latch, and ensuring that the roller body is located on the left side of the limit latch;

[0017] S3, adjusting the axis center position of the shaft body through the adjustment mechanism so that it corresponds to the push rod;

[0018] S4. Start the oil cylinder to extend it and drive the push rod to move. The push rod pushes the shaft body to the right. Since the limit latch has a limiting effect on the roller body, the shaft body can be pushed out of the roller body under the push of the push rod, thereby realizing the disassembly of the roller.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. This roller disassembly device is specially designed to solve the problem that the roller shaft and roller body are difficult to disassemble due to interference fit. The oil cylinder drives the push rod to push the shaft, and the mechanical force is used to realize the disassembly of the roller, which greatly improves the disassembly efficiency.

[0021] Second, the setting of the adjustment mechanism of the roller disassembly device helps to protect the structure of the roller during the disassembly process. During disassembly, the adjustment mechanism can adjust the axis position of the shaft body so that it accurately corresponds to the push rod. This can avoid the generation of additional friction or lateral force due to the misalignment of the axis when the push rod pushes the shaft body, thereby preventing unnecessary wear or damage to the shaft body and the roller body.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0029] Example 1

[0030] See also Figure 1-2 A roller disassembly device includes a frame 1, a controller 2 is arranged on the frame 1, a working groove 3 is opened on the top of the frame 1, the working groove 3 is used to accommodate a roller 4, the roller 4 includes a shaft body 41 and a roller body 42, the roller body 42 is sleeved on the shaft body 41, and the shaft body 41 and the roller body 42 are interference fit.

[0031] A cylinder 5 fixedly connected to the frame 1 is inserted on the left side thereof, and the cylinder 5 extends into the working groove 3, and a push rod 6 is fixedly connected to the output shaft of the cylinder 5; a plurality of groups of latch holes 7 are provided on the frame 1 and on the front and rear sides of the working groove 3, and a limit latch 8 is inserted into one group of latch holes 7, and a through hole 9 is provided on the limit latch 8, and the limit latch 8 is sleeved on the shaft body 41 through the through hole 9.

[0032] When disassembling the roller 4 in this embodiment, the limit latch 8 is first inserted into the corresponding latch hole 7 according to the length of the shaft body 41, and then the shaft body 41 of the roller 4 is inserted into the through hole 9 of the limit latch 8, and the oil cylinder 5 drives the push rod 6 to push the shaft body 41, and the roller 4 is quickly disassembled by mechanical force. The limit latch 8 in the device plays a key limiting role. When the push rod 6 pushes the shaft body 41, it can ensure the stability of the position of the roller body 42, so that the shaft body 41 can be smoothly pushed out of the roller body 42, avoiding the disassembly obstacle caused by the shaking or displacement of the roller body 42, and further improving the efficiency of disassembly.

[0033] Example 2

[0034] See also Figure 2-3 This embodiment is a further improvement made on the basis of the embodiment 1. Compared with the embodiment 1, in order to avoid the generation of additional friction or lateral force due to the misalignment of the axis when the push rod 6 pushes the shaft 41, thereby preventing unnecessary wear or damage to the shaft 41 and the roller 42, the center of the through hole 9 is exactly corresponding to the axis of the push rod 6, and the limit latch 8 is provided with an adjustment mechanism 10 for keeping the shaft 41 and the through hole 9 concentric.

[0035] Furthermore, a receiving groove 11 is provided on the right side of the limit latch 8 and on the periphery of the through hole 9 , and the adjustment mechanism 10 is located in the receiving groove 11 and does not protrude from the limit latch 8 , thereby ensuring that the limit latch 8 can be normally installed on the frame 1 through the latch hole 7 .

[0036] Specific: such as Figure 3As shown, the adjustment mechanism 10 includes two opposite arc plates 101, and elastic members 102 are provided on the opposite sides of the two arc plates 101, and the two elastic members 102 are respectively connected to the limit latch 8. The arc plates 101 and the elastic members 102 are both located in the accommodating groove 11, and the opposite sides of the two arc plates 101 are rotatably connected with a number of evenly distributed balls 103. The elastic force of the elastic member 102 can adaptably adjust the aperture of the through hole 9 according to the diameter of the shaft body 41. Specifically, if the diameter of the shaft body 41 is large, the elastic member 102 will be compressed, thereby increasing the distance between the two arc plates 101, thereby expanding the aperture of the variable "through hole 9"; on the contrary, if the diameter of the shaft body 41 is small, the elastic restoring force of the elastic member 102 will reduce the distance between the two arc plates 101, reducing the aperture of the "through hole 9". In this way, it can be ensured that the shaft bodies 41 of different diameters can accurately correspond to the axis of the push rod 6.

[0037] This ensures that the shaft bodies 41 of different diameters can correspond to the axis of the push rod 6, avoiding additional friction or lateral force caused by misalignment of the axis.

[0038] When the shaft 41 moves between the two arc-shaped plates 101, the sliding friction between the shaft 41 and the arc-shaped plates 101 that may have existed originally is converted into rolling friction due to the existence of the balls 103. Rolling friction has a smaller friction force than sliding friction, which ensures that the shaft 41 can pass through the area surrounded by the arc-shaped plates 101 more smoothly, further ensuring the fluency and efficiency of the entire disassembly process.

[0039] More specifically, Figure 4 As shown, the elastic member 102 includes a housing 1021, which is located in the accommodating groove 11 and fixedly mounted on the limit latch 8 by bolts, and a connecting rod 1022 is inserted through the housing 1021, and the connecting rod 1022 is fixedly connected to the arc plate 101, and one end of the arc plate 101 located in the housing 1021 is fixedly connected to a limit block 1023, and one end of the limit block 1023 away from the connecting rod 1022 is fixedly connected to a spring 1024, and the spring 1024 is fixedly connected to the inner wall of the housing 1021. When the diameter of the shaft body 41 changes, the arc plate 101 will be subjected to the pressure of the shaft body 41 or will be displaced due to its own elastic restoring force, and this displacement will be transmitted to the limit block 1023 through the connecting rod 1022, so that the spring 1024 will be elastically deformed. The spring 1024 generates a corresponding elastic force according to the deformation, and this elastic force reacts on the arc plate 101 , thereby realizing the function of adaptively adjusting the aperture of the through hole 9 according to the diameter of the shaft body 41 .

[0040] In addition, the limit block 1023 is a polygonal structure and is in smooth contact with the inner wall of the shell 1021. The design of the polygonal structure allows the movement of the limit block 1023 in the shell 1021 to have certain guidance and stability.

[0041] A working method of a roller disassembly device comprises the following steps:

[0042] S1, insert the limit latch 8 into the latch hole 7, so that the limit latch 8 is mounted on the frame 1;

[0043] S2, insert the shaft 41 of the roller 4 into the through hole 9 of the limit latch 8, and ensure that the roller body 42 is located on the left side of the limit latch 8;

[0044] S3, adjusting the axis position of the shaft body 41 through the adjustment mechanism 10 so that it corresponds to the push rod 6;

[0045] S4. Start the oil cylinder 5 to extend it, drive the push rod 6 to move, and the push rod 6 pushes the shaft body 41 to the right. Since the limit latch 8 has a limiting effect on the roller body 42, the shaft body 41 can be pushed out of the roller body 42 under the push of the push rod 6, thereby realizing the disassembly of the roller 4.

[0046] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
