Description

Technical Field

[0001] This utility model belongs to the field of ribbon weaving machine technology, and in particular to a ribbon weaving machine with a clutch bearing. Background Technology

[0002] A ribbon weaving machine is a machine that can weave ribbons of various widths. According to the specific weaving method, it can be divided into two main categories: shuttle weaving machines and braided ribbon machines. Existing ribbon weaving machines use a one-way bearing to drive the bearing of the pressure and take-up mechanism to rotate. During normal rotation, the one-way bearing drives the pressure and take-up mechanism to rotate. When the pressure and take-up mechanism needs to be reversed to release the weaving, the one-way bearing needs to be reversed, and the rotation is achieved manually.

[0003] Because one-way bearings have high precision but low load-bearing capacity, they cannot be used for large-size pressure winding rotation, which affects the mechanical size and makes them unsuitable for large ribbon weaving machines. To solve this problem, a ribbon weaving machine with a clutch-type bearing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a weaving machine with a clutch bearing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ribbon weaving machine with a clutch-type bearing, comprising:

[0006] The main body of the ribbon weaving machine has a pressure-applying and tape-taking mechanism bolted to its top.

[0007] A one-way bearing mechanism for releasing the webbing in the reverse pressure take-up mechanism of a webbing machine body. The one-way bearing mechanism includes a bearing housing and a main shaft. The inner wall of the bearing housing is rotatably connected to the main shaft. A movable gear is movably connected to the side of the main shaft. A meshing gear one is connected to the side of the movable gear. A meshing gear two meshes with the side of the meshing gear one. The outer wall of the meshing gear two is slidably connected to the bearing housing. A ring-shaped groove is opened on the outer ring surface of the meshing gear two. A return spring is sleeved on the inner wall of the groove of the meshing gear two. A limit plate is connected to the end face of the return spring. Two sliding grooves are opened on the inner ring surface of the meshing gear two. Movable protrusions are slidably connected to the inner wall of the sliding grooves of the meshing gear two. The two movable protrusions are connected and fixed to the main shaft on their adjacent sides.

[0008] Preferably, the side wall of the first meshing gear has a through groove for the main shaft to pass through, and the side wall of the second meshing gear has a through groove for the main shaft to slide.

[0009] Preferably, the side of the limiting plate has a through groove, and the inner wall of the through groove of the limiting plate is connected and fixed to the main shaft.

[0010] Preferably, the inner cavity of the bearing housing is provided with an annular groove, and a rotating plate is rotatably connected to the inner wall of the groove of the bearing housing.

[0011] Preferably, the side of the rotating plate is fixedly connected to the main shaft, and a linkage gear is provided on the side of the movable gear away from the meshing gear.

[0012] Preferably, the side of the linkage gear is embedded and fixedly connected to the main shaft, and a fixed bearing is provided on the side wall of the linkage gear.

[0013] Preferably, the inner ring of the fixed bearing is interference-fitted with the rotating shaft of the pressure-applying and winding mechanism, and the outer ring of the fixed bearing meshes with the movable gear through a gear.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0015] This weaving machine with a clutch-type bearing uses a one-way bearing mechanism to drive the pressure take-up mechanism. When the pressure take-up mechanism needs to reverse to release the weaving, the main shaft of the one-way bearing mechanism needs to reverse, which is manually achieved. However, existing one-way bearing mechanisms have high precision but low load-bearing capacity, making them unsuitable for large-size pressure take-up rotation. This affects the machine's size and makes it unsuitable for large weaving machines. This causes the linkage gear to reverse. Since the meshing between meshing gear one and meshing gear two does not have a reverse meshing linkage structure, meshing gear two extends into the inner cavity of the bearing housing, providing conditions for the relative rotation of the movable gear and the rotating shaft. This allows the two movable protrusions to slide along the inner wall of the groove of meshing gear two, strengthening the structural stability of the clutch-type bearing components. This clutch-type bearing can improve load-bearing strength, is suitable for large weaving machines, and is low in cost and high in efficiency.

[0016] In this weaving machine with a clutch bearing, after the second meshing gear extends into the inner cavity of the bearing housing, the second meshing gear and the limiting plate squeeze the return spring. When the pressure take-up mechanism needs to rotate forward, the linkage gear rotates in the opposite direction again. Under the elastic thrust provided by the return spring, the second meshing gear extends out of the bearing housing. At the same time, the two movable protrusions move along the inner wall of the groove of the second meshing gear, realizing the meshing of the second meshing gear and the first meshing gear.

[0017] This ribbon weaving machine with a clutch-type bearing has a one-way bearing mechanism that enables the main shaft to rotate in both directions, providing conditions for the reverse rotation of the pressure take-up mechanism. The clutch-type bearing can improve the bearing strength, is suitable for large ribbon weaving machines, and is low in cost and high in efficiency. Attached Figure Description

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0029] To address the issue that one-way bearings, due to their high precision but low load-bearing capacity, are unsuitable for large-scale pressure winding rotation in ribbon weaving machines, thus affecting machine dimensions and making them incompatible with large-scale weaving machines, please refer to [the relevant documentation / reference]. Figures 1 to 5 The structure of the device body includes:

[0030] The main body of the ribbon weaving machine 1 has a pressure-applying and take-up mechanism 2 bolted to the top of the main body of the ribbon weaving machine 1.

[0031] A one-way bearing mechanism 4 is used for the reverse pressure and take-up mechanism 2 of the main body 1 of the ribbon weaving machine to release the ribbon. The one-way bearing mechanism 4 includes a bearing housing 5 and a main shaft 6. The inner wall of the bearing housing 5 is rotatably connected to the main shaft 6. A movable gear 7 is movably connected to the side of the main shaft 6. A meshing gear 8 is connected to the side of the movable gear 7. A meshing gear 9 meshes with the side of the meshing gear 8. The outer wall of the meshing gear 9 is slidably connected to the bearing housing 5. A ring-shaped groove is opened on the outer ring surface of the meshing gear 9. A return spring 11 is sleeved on the inner wall of the groove of the meshing gear 9. A limit plate 12 is connected to the end face of the return spring 11. Two sliding grooves are opened on the inner ring surface of the meshing gear 9. Movable protrusions 10 are slidably connected to the inner wall of the sliding grooves of the meshing gear 9. The two movable protrusions 10 are connected and fixed to the main shaft 6 on adjacent sides.

[0032] In this embodiment, the main body 1 of the weaving machine drives the fixed bearing 3 of the pressure take-up mechanism 2 to rotate through a one-way bearing mechanism 4. During normal rotation, the one-way bearing mechanism 4 drives the pressure take-up mechanism 2 to rotate. When the pressure take-up mechanism 2 needs to be reversed to release the weaving, the one-way bearing mechanism 4 needs to be reversed, and the rotation is manually achieved. The gears of meshing gear 1 8 and meshing gear 2 9 are in an inclined V-shape. One tooth surface of meshing gear 1 8 and meshing gear 2 9 extends parallel to the main shaft 6, and the other tooth surface of meshing gear 1 8 and meshing gear 2 9 extends in an inclined direction to the main shaft 6. This provides conditions for the meshing of the forward rotation of meshing gear 1 8 and meshing gear 2 9 and the mutual friction of the reverse rotation of the tooth surfaces of meshing gear 1 8 and meshing gear 2 9, thereby realizing the meshing of meshing gear 1 8 and meshing gear 2 9 of the clutch bearing. When the fixed bearing 3 of the pressure-retracting mechanism 2 needs to reverse, the main shaft 6 of the one-way bearing mechanism 4 reverses relative to its initial state, realizing the centrifugal movement of the meshing gear 1 8 and the meshing gear 2 9. The meshing gear 2 9 extends into the inner cavity of the bearing housing 5, and the meshing gear 2 9 and the limiting plate 12 press the return spring 11. At the same time, the two movable protrusions 10 slide along the inner wall of the two sliding grooves of the meshing gear 2 9. When the meshing gear 2 9 extends into the inner cavity of the bearing housing 5, it provides conditions for the relative rotation of the movable gear 7 and the main shaft 6, thereby releasing the linkage rotation between the main shaft 6 and the rotating shaft of the pressure-retracting mechanism 2, providing conditions for the reversal of the pressure-retracting mechanism 2, improving the structural stability of the clutch bearing components, enabling the clutch bearing to improve its bearing strength, adapt to large weaving machines, and achieve low cost and high efficiency.

[0033] Specifically, the side wall of the first meshing gear 8 has a through groove for the main shaft 6 to pass through, and the side of the second meshing gear 9 has a through groove for the main shaft 6 to slide.

[0034] In this embodiment, the main shaft 6 is connected and fixed to the meshing gear 8, while the meshing gear 9 can move along the path of the main shaft 6 to realize the engagement and disengagement of the clutch bearing.

[0035] Specifically, the limiting plate 12 has a through groove on its side, and the inner wall of the through groove of the limiting plate 12 is connected and fixed to the main shaft 6. The inner cavity of the bearing housing 5 has an annular groove, and the inner wall of the groove of the bearing housing 5 is rotatably connected to a rotating plate 13. The side of the rotating plate 13 is embedded and fixedly connected to the main shaft 6.

[0036] In this embodiment, a through groove is provided on the side of the rotating plate 13. The inner wall of the through groove of the rotating plate 13 is connected and fixed to the main shaft 6, so as to realize the synchronous and co-rotation of the main shaft 6 and the rotating plate 13. At the same time, the bearing housing 5 is provided to fix the rotation position of the rotating plate 13. Under the connection provided by the rotating plate 13, the bearing housing 5 fixes the rotation position of the main shaft 6, thereby improving the structural stability of the clutch bearing components.

[0037] Specifically, a linkage gear 14 is provided on the side of the movable gear 7 away from the meshing gear 8. The side of the linkage gear 14 is embedded and fixedly connected to the main shaft 6. A fixed bearing 3 is provided on the side wall of the linkage gear 14. The inner ring of the fixed bearing 3 is interference-fitted with the rotating shaft of the pressure winding mechanism 2. The outer ring of the fixed bearing 3 meshes with the movable gear 7 through a gear.

[0038] In this embodiment, the movable gear 7 and the meshing gear 8 abut against each other on their adjacent sides, thereby connecting and fixing the linkage gear 14 to the main shaft 6. This provides the conditions for the synchronous and co-rotating of the linkage gear 14 and the main shaft 6, as shown in the accompanying drawings. Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, when the movable gear 7 rotates clockwise, under the meshing of meshing gear 8 and meshing gear 9, the meshing gear 8 and meshing gear 9 rotate synchronously in the same direction. Under the action of the fixed bearing 3's outer ring meshing with the movable gear 7 through the gear, the rotating shaft of the pressure winding mechanism 2 rotates counterclockwise.

[0039] Working principle

[0040] When the user needs to reverse the pressure take-up mechanism 2, the gear of the fixed bearing 3 of the pressure take-up mechanism 2 meshes with the movable gear 7, causing the movable gear 7 to rotate in the opposite direction. This reverse rotation automatically disengages the meshing gear 1 8 and the meshing gear 2 9, causing the meshing gear 2 9 to press against the return spring 11 with the limit plate 12, thus achieving relative rotation between the movable gear 7 and the main shaft 6.

[0041] When the pressure-applying and winding mechanism 2 rotates forward, under the elastic thrust provided by the return spring 11, the meshing gear 2 9 extends out of the bearing housing 5, so that the meshing gear 2 9 meshes with the meshing gear 1 8, realizing the linkage rotation of the rotating shaft of the pressure-applying and winding mechanism 2 and the main shaft 6.
