Description

Technical Field

[0001] This utility model relates to the field of hose manufacturing technology, specifically to a hose vulcanization traction device. Background Technology

[0002] Vulcanization is a crucial process in hose production, used to bond the outer strip and inner hose together using steam heating. During vulcanization, the inner hose needs to be threaded into the outer strip, typically using a traction trolley to move back and forth. Because the traction trolley needs to move back and forth and constantly change position, it requires a constant power supply. Therefore, a sliding contact line is usually used to control the traction trolley. The traction trolley moves on an I-beam track parallel to the vulcanizing table, and a current collector is installed on the trolley to draw power from the conductor. As the traction trolley moves, the current collector draws power from the conductor to support its movement. However, the sliding contact line has very high requirements for the parallelism between the track and the conductor, the parallelism between the tracks, and the inclination. Furthermore, due to the installation errors of the I-beam track itself, the long-term movement of the wheels will also cause track wear, resulting in unstable current due to excessive or insufficient contact between the current collector brush and the conductor. This shortens the service life of the trolley motor and the sliding contact line, and makes the trolley movement unstable, posing safety hazards to the operator. At the same time, the excessive dust and high temperature in the vulcanization workshop are not conducive to the use of the sliding contact line, increasing the cost of daily inspection and maintenance.

[0016] like Figure 1 As shown, a hose vulcanization traction device 1 is connected to a hose 2 and is used to pull the hose 2 back and forth during vulcanization. The hose 2 is placed on a vulcanization table 3, and the vulcanization table 3 bonds the outer layer of the hose 2 and the inner layer of the hose.

[0017] Please combine Figure 1 and Figure 2 The traction device 1 includes a track 11, a traction trolley 12, a motor 13, a power supply 14, wires 15, and a winding assembly 16. The track 11 is arranged parallel to one side of the vulcanizing table 3. The traction trolley 12 moves on the track 11 and is connected to the hose 2 for hose insertion. The motor 13 is mounted on the traction trolley 12 and drives it to move along the track 11. The power supply 14 is electrically connected to the motor 13 via the wires 15. The power supply 14 supplies power to the motor 13; the winding assembly 16 is located between the power supply 14 and the traction trolley 12, the wire 15 is wound around the winding assembly 16, and the winding assembly 16 is used to wind up the wire 15. When the traction trolley 12 moves away from the winding assembly 16, the traction trolley 12 pulls the wire 15, and the winding assembly 16 unwinds; when the traction trolley 12 moves towards the winding assembly 16, the winding assembly 16 automatically winds up.

[0018] Please combine Figure 2 and Figure 3The winding assembly 16 includes a base 161, wall panels 162, mounting holes 163, a roller 164, a baffle 165, a bearing 166, a torsion spring 167, and a bearing cap 168. The wall panels 162 are vertically arranged on both sides of the base 161. The mounting holes 163 are formed on the wall panels 162. The roller 164 is thicker in the middle and thinner at both ends, with the thicker middle portion forming the main body and the thinner ends forming the shaft. The two ends of the roller 164 are respectively mounted between the wall panels 162 through the mounting holes 163. The wire 15 is wound around the roller 164. The baffle 165 is symmetrically fitted onto the roller 164, located at the junction of the main body and the shaft of the roller 164, to prevent the wire 15 from winding around the shaft of the roller 164. This affects the winding effect of the winding assembly 16; the bearing 166 is fitted at both ends of the roller shaft 164 and located in the mounting hole 163. The bearing 166 is used to support the roller shaft 164, reduce the coefficient of friction during the rotation of the roller shaft 164, and enable the roller shaft 164 to rotate flexibly; the torsion spring 167 is fitted at both ends of the roller shaft 164 and connected to the bearing 166. During unwinding, the rotation of the roller shaft 164 causes the torsion spring 167 to be deformed by force. During winding, the torsion spring 167 releases elastic potential energy, causing the roller shaft 164 to rotate in the opposite direction for winding; the bearing cover 168 is fitted at both ends of the roller shaft 164, the bearing cover 168 abuts against the bearing 166, and the bearing cover 168 is located outside the torsion spring 167.

[0019] The roller 164 may also be provided with a wire routing channel 1641. The wire routing channel 1641 is opened at one end of the roller 164 near the power source 14. The wire routing channel 1641 is L-shaped. As shown in the figure, the wire routing channel 1641 is divided into sections A and B. Section A is the part that is horizontally opened from the center position of the shaft of the roller 164 to the main body position of the roller 164. Section B is the part that is vertically opened through the main body position of the roller 164. One end of the wire 15 is connected to the power source 14, and the other end passes through the wire routing channel 1641 and is wound around the roller 164, and then connected to the motor 13. The wire routing channel 1641 is used to fix the wire 15 to be wound from section B. At the same time, during winding, section B also provides a certain tension to prevent the wire 15 from slipping on the roller 164.

[0020] The traction trolley 12 is connected to the power supply 14 via the wire 15. The motor 13 drives the traction trolley 12 to move along the track 11. When the traction trolley 12 moves away from the winding assembly 16, the traction trolley 12 pulls the wire 15, the roller 164 rotates, causing the torsion spring 167 to deform under force, and the winding assembly 16 unwinds the wire. When the traction trolley 12 moves towards the winding assembly 16, the torsion spring 167 releases its elastic potential energy, causing the roller 164 to rotate in the opposite direction, and the winding assembly 16 winds up the wire.

[0021] In summary, this invention is more suitable for the dusty environment of vulcanizing workshops compared to sliding contact line control. The current of the traction trolley is more stable during operation, which improves operational safety. At the same time, this invention has low maintenance costs and is easy to maintain.

[0022] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit this utility model. Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model.
