Description

Technical Field

[0001] The utility model relates to the technical field of textile accessories, and specifically relates to a spinning roller. Background Art

[0002] The spinning roller, also known as the spinning rubber roller, is a rubber roller used in the drafting mechanism of spinning machinery. It consists of a shaft core, a sleeve shell, and an outer rubber layer. It can be divided into several types according to its use, such as drawframe rubber rollers, comber rubber rollers, roving rubber rollers, and ring spinning rubber rollers, etc. It is required to have a smooth surface, oil resistance, wear resistance, good elasticity, small deformation, and no fiber entanglement, and it can hold the fibers well. It is often made of nitrile rubber, gelatin, and bone glue. Currently, the Shore hardness of the outer rubber sleeve of the spinning roller on the market is mostly a fixed value, and the surface hardness cannot be adjusted according to different fiber yarns (the surface hardness of the rubber sleeve is generally Shore 65° - 85° for cotton spinning; Shore 75° - 85° for wool spinning; Shore 85° - 90° for hemp spinning; and about Shore 75° for silk spinning). It is necessary to disassemble and replace the rubber sleeve on the outer wall of the yarn-releasing roller, which is rather troublesome and not convenient for enterprises to carry out efficient operations. Content of the Utility Model

[0003] The purpose of the utility model is to provide a spinning roller to solve the problem proposed in the above background art that the Shore hardness of the outer rubber sleeve of the spinning roller on the market is mostly a fixed value, and the surface hardness cannot be adjusted according to different fiber yarns (the surface hardness of the rubber sleeve is generally Shore 65° - 85° for cotton spinning; Shore 75° - 85° for wool spinning; Shore 85° - 90° for hemp spinning; and about Shore 75° for silk spinning). It is necessary to disassemble and replace the rubber sleeve on the outer wall of the yarn-releasing roller, which is rather troublesome and not convenient for enterprises to carry out efficient operations.

[0004] To achieve the above object, the present utility model provides the following technical solutions: A spinning roller includes a substrate. On one side of the substrate, a roller body mechanism is provided. On the other side of the substrate, a cone pulley is provided. The roller body mechanism includes a cavity roller, a cavity sleeve, a riser pipe, an exhaust valve, a sealing plate, a pull rod, a handle, a sleeve plate, a rubber ring, a first one-way valve, and a second one-way valve. The cavity roller is horizontally located on one side of the substrate. The outer wall of the cavity roller is sleeved with a cavity sleeve. A plurality of riser pipes are evenly arranged between the cavity sleeve and the cavity roller. The upper and lower sides of the outer wall of the riser pipe are fixedly connected to the contact surfaces of the cavity sleeve and the cavity roller respectively. On the other side of the bottom end of the outer wall of the cavity roller, an exhaust valve is fixedly connected. At one end of one side of the cavity roller, a sealing plate is fixedly connected. Inside the sealing plate, a pull rod is provided. At one end of one side of the pull rod, a handle is fixedly connected. At the other end of the outer wall of the pull rod, a sleeve plate is fixedly sleeved. On the outer wall of the sleeve plate, a rubber ring is fixedly sleeved. The rubber ring abuts tightly against the inner wall of the cavity roller. On one side surface of the sleeve plate, two first one-way valves are fixedly connected in sequence from top to bottom. A part of the first one-way valve penetrates through the sleeve plate. On one side surface of the sealing plate, two second one-way valves are fixedly connected in sequence from top to bottom. A part of the second one-way valve penetrates through the sealing plate.

[0005] Preferably, a pressure gauge is provided above the exhaust valve. The pressure gauge is fixedly connected to the cavity roller.

[0006] Preferably, the cavity roller is connected to the substrate through a connecting mechanism. The connecting mechanism includes a square block, a vertical groove, a sliding rod, a convex block, a screw rod, and a knob. The square block is located inside the substrate. The square block is slidably connected to the substrate through the vertical groove. The square block is rotatably connected to the cavity roller through a ball bearing. At the four corners of the upper surface of the square block, sliding rods are inserted. The sliding rods penetrate through the square block. The upper and lower ends of the sliding rods are fixedly connected to the contact surfaces of the substrate. At the center of the front surface of the square block, a convex block is fixedly connected. Inside the convex block, a screw rod is threadedly connected. The screw rod is rotatably connected to the substrate through a ball bearing. The top end of the screw rod is fixedly connected to the knob.

[0007] Compared with the prior art, the beneficial effects of the present utility model are as follows: This spinning roller has the following advantages compared with the traditional technology:

[0008] Through the cooperation among the substrate, the roller body mechanism, and the cone pulley, a reciprocating force is applied to the handle to make the sleeve plate and the rubber ring move horizontally intermittently together. During this period, external air can be continuously injected into the interior of the cavity roller. Since the interior of the cavity roller can be interconnected with the interior of the cavity sleeve through the riser pipe, the air pressure inside the cavity sleeve can be increased and the surface can expand, thereby increasing the Shore hardness of the outer surface of the cavity sleeve. After the exhaust valve is opened and closed, the air inside the cavity roller can be depressurized, and the Shore hardness of the outer surface of the cavity sleeve can be adjusted to be smaller, so as to meet the requirements of different yarns for the surface hardness of the cavity sleeve. There is no need to disassemble and replace the cavity sleeve, which is convenient for enterprises to carry out efficient operations.

[0009] Through the cooperation among the substrate, the roller mechanism, the cone pulley and the connecting mechanism, a force is applied to the knob to rotate the screw rod, so as to adjust the vertical height position of the square block and the cavity sleeve. On the premise that the outer wall of the cavity sleeve can be repeatedly pressed against the external yarn, the pressing force between the cavity sleeve and the yarn can be adjusted.

[0019] During the use of the spinning roller, first, the cone pulley 4 is connected to an external driving device through a belt, which can provide the kinetic energy required for the rotation of the cone pulley 4, the cavity roller 201, and the cavity sleeve 202. When the outer wall of the cavity sleeve 202 in the rotating state contacts the yarn, it can provide the potential energy required for traction. Before this operation, the staff can apply reciprocating force to the handle 207 to make the sleeve plate 208 and the rubber ring 209 move horizontally intermittently. During this period, external air can be continuously injected into the interior of the cavity roller 201. Since the interior of the cavity roller 201 can be interconnected with the interior of the cavity sleeve 202 through the riser pipe 203, the air pressure inside the cavity sleeve 202 can increase and the surface expands, which can then increase the Shore hardness of the outer surface of the cavity sleeve 202. After opening and closing the exhaust valve 204, the air inside the cavity roller 201 can be depressurized, and the Shore hardness of the outer surface of the cavity sleeve 202 can be reduced, so as to meet the requirements of different yarns for the surface hardness of the cavity sleeve 202. There is no need to disassemble and replace the cavity sleeve 202, which is convenient for enterprises to carry out efficient operations.
