Description

Technical Field

[0001] This utility model relates to the technical field of hose traction, and in particular to a traction device for the production of PVC plastic hoses. Background Technology

[0002] The production process of PVC hoses consists of material preparation, material mixing and kneading, granulation, extrusion molding, traction and cooling, coiling and packaging. After the hose is extruded, it needs to be cooled to prevent secondary deformation during transportation. Then the hose enters the traction device, and the overall movement of the hose is provided by the traction device. The hose is generally cooled by spraying or immersion.

[0003] The prior art Chinese utility model patent with application number CN202323001967.5 relates to a PVC hose traction device, which includes a base, an electric push rod, a lifting plate, a side plate, a rotating roller, a stepper motor, a rubber belt, and a guide roller, etc., which can prevent the PVC hose from deviating when traction and can traction multiple PVC hoses at the same time.

[0004] However, the above-mentioned device does not have the ability to clean the residual liquid on the hose in actual use. After the hose passes through the cooling device, some liquid will remain on the surface. The liquid drips down as the hose moves, which will pollute the production environment. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a traction device for the production of PVC plastic hoses. It uses a lifting device to enable the equipment to adapt to hoses of different diameters, a traction device to pull the hose, a drying device to clean the residual liquid on the hose to reduce the pollution of the operating environment caused by liquid dripping, and a limiting device to limit the lateral position of the hose to prevent the hose from deviating laterally during traction and causing property damage. This improves the practicality of the device.

[0006] This utility model discloses a traction device for the production of PVC plastic hoses; it includes a lifting device, a traction device, a drying device, and a limiting device. The traction device, the drying device, and the limiting device are all mounted on the lifting device. The lifting device allows the equipment to adapt to hoses of different diameters. The traction device pulls the hose, the drying device cleans residual liquid on the hose, reducing the pollution of the operating environment caused by liquid dripping, and the limiting device limits the lateral position of the hose, preventing the hose from deviating laterally during traction and causing property damage, thus improving the practicality of the device.

[0007] Preferably, the lifting device includes a support frame, a lifting frame, limiting rods, limiting sleeves, a hydraulic cylinder, and a support frame. A hydraulic cylinder is installed in the center of the bottom end face of the support frame, and a support frame is installed on the moving end of the hydraulic cylinder. The upper part of the support frame is connected to the lower end face of the lifting frame via multiple sets of support columns at the front and rear. Multiple sets of limiting sleeves are evenly distributed on the left and right sides of the front and rear end faces of the support frame. Multiple sets of limiting rods are vertically installed on the front and rear end faces of the lifting frame corresponding to the positions of the limiting sleeves via brackets. The multiple sets of limiting rods pass through the corresponding limiting sleeves on their lower sides. By controlling the extension of the hydraulic cylinder, the height of the lifting frame is changed, thereby adjusting the height of the traction device. This allows the traction device to be adjusted according to pipes of different diameters, enabling the equipment to provide traction for pipes of different diameters, improving the adaptability of the device. The multiple sets of limiting rods and limiting sleeves work together to limit the lifting process of the lifting frame, improving the stability of the device.

[0008] Preferably, the traction device includes conveyor rollers, conveyor belts, and a first motor. Multiple sets of conveyor rollers are horizontally installed in the upper part of the support frame and the lower part of the lifting frame. Two sets of conveyor belts are respectively fitted onto the multiple sets of conveyor rollers in the upper and lower parts. A first motor is installed on the left side of the front end face of the support frame and the lifting frame. The output ends of the two sets of first motors are respectively connected to the outermost set of conveyor rollers. When the first motor is turned on, power is transmitted to the conveyor rollers connected to them, causing the conveyor rollers to rotate. The multiple sets of conveyor rollers drive the conveyor belts to rotate. The upper and lower sets of conveyor belts clamp the hose, driving the pipe to move and providing traction force for the pipe, thus improving the practicality of the device.

[0009] Preferably, the drying device includes a bracket, a second motor, and a brush roller. A set of brackets is connected to the middle of the right end face of the lifting frame and the front and rear of the right end face of the support frame, respectively. The brush roller is installed on the bracket, and the second motor is installed on the left side face of the bracket. The output end of the second motor is connected to the brush roller. Turning on the second motor transmits power to the brush roller, which drives the brush roller to rotate, thereby wiping off the residual liquid on the hose, reducing the pollution caused by the residual liquid on the hose to the subsequent processing environment, and improving the practicality of the device.

[0010] Preferably, it also includes a fan and a strip nozzle. The fan is installed on the side of the bracket body, and the strip nozzle is set on the side of the bracket close to the brush roller. The output end of the fan is connected to the strip nozzle. When the fan is turned on, the outside air is sent out through the strip nozzle, so that the air is blown toward the brush roller to accelerate the removal of liquid from the brush roller itself, ensure the working effect of the drying device, and improve the practicality of the device.

[0011] Preferably, the limiting device includes a third motor, a bidirectional lead screw, a transverse platform, a nut, and a limiting rod. A transverse slide rail is provided on the right side of the upper end face of the lifting frame, and a third motor is installed on the right side of the front end face of the lifting frame. A bidirectional lead screw is installed in the transverse slide rail, and the output end of the third motor is connected to the bidirectional lead screw. Two sets of transverse platforms are connected to the bidirectional lead screw through nuts, and the two sets of transverse platforms are located symmetrically on the bidirectional lead screw. A limiting rod is connected to the lower end face of the transverse platform. When the third motor is turned on, power is transmitted to the bidirectional lead screw to drive the bidirectional lead screw to rotate. The rotating bidirectional lead screw drives the two sets of transverse platforms to move in opposite directions or back to back through the nut, thereby adjusting the position of the limiting rod. The limiting rod restricts the position of the hose, preventing the hose from falling off the traction device and improving the practicality of the device.

[0012] Preferably, the device also includes a reducer, a motor, and a cleaning roller. A reducer is installed on the left side of the rear end face of the inner support frame, and a motor is installed on the reducer. A cleaning roller is connected to the output end of the reducer. The front part of the cleaning roller is connected to the front part of the support frame through a bearing seat. When the motor is turned on, the power is transmitted to the cleaning roller through the reducer to drive the cleaning roller to rotate. The rotating cleaning roller removes the impurities remaining on the surface of the upper conveyor belt, preventing the impurities on the surface of the conveyor belt from scratching the surface of the hose during the traction process, thus improving the practicality of the device.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the lifting device enables the equipment to adapt to hoses of different diameters, the traction device pulls the hose, the drying device cleans the residual liquid on the hose, reducing the pollution caused by liquid dripping to the operating environment, and the limiting device limits the lateral position of the hose, preventing the hose from deviating laterally during the traction process and causing property damage, thus improving the practicality of the device.
