Description

Technical Field

[0001] This utility model relates to the field of PVC hose technology, specifically to a semi-automatic PVC hose winding machine. Background Technology

[0002] Flexible PVC pipes are made by adding a large amount of plasticizer, a certain amount of stabilizer, and other additives to PVC resin, and then extruding them. Flexible PVC pipes have excellent chemical stability, excellent electrical insulation properties, and good flexibility and colorability. This type of pipe is often used to replace rubber pipes for transporting liquids and corrosive media, and is also used as cable conduit and wire insulation.

[0003] A search of publication number "CN210418724U" reveals a "high-pressure hose winding machine, including a base, a frame fixedly connected to the upper side wall of the base, a first through hole through the side wall of the frame, a motor fixedly connected to one side wall of the frame, the output shaft of the motor being rotatably connected to the inner wall of the first through hole via a first bearing, the end of the motor output shaft passing through the first through hole and fixedly connected to a rotating shaft, a winding reel slidably sleeved on the rotating shaft, a limiting mechanism between the rotating shaft and the winding reel, a limiting collar fixedly sleeved on the side wall of the rotating shaft near the frame, and the side wall of the winding reel near the frame abutting against the limiting collar. This utility model saves time and labor, reduces the labor intensity of workers, facilitates the fixing of the winding reel, and also facilitates the removal of the winding reel of the wound high-pressure hose from the winding machine, thus improving efficiency." The aforementioned patent facilitates the fixing and disassembly of the winding reel, making it convenient to store the subsequent hose. However, when storing the hose, the aforementioned patent can easily lead to the stacking of the hose, which causes the hose to be subjected to unnecessary torque, pressure and bending. Under such stress for a long time, the pipe (especially the reinforcing layer inside the hose) will undergo permanent deformation, resulting in changes in its roundness, damage to the internal structure, and affecting the subsequent use of the hose. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a semi-automatic PVC hose winding machine, which can effectively solve the problem of hose stacking during use in the existing technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a semi-automatic PVC hose winding machine, including two mounting discs. Mounting blocks are fixedly connected to the circumferential surfaces of the two mounting discs. A lead screw is rotatably connected to the adjacent ends of the two mounting blocks. A lead screw nut is threaded onto the circumferential surface of the lead screw. A flat ring is fixedly connected to the circumferential surface of the lead screw nut. A take-up roller is rotatably connected to the adjacent ends of the two mounting discs. A drive mechanism is provided at one end of one of the mounting discs. The drive mechanism is used to drive the lead screw and the take-up roller to rotate.

[0006] Furthermore, the drive mechanism consists of a motor, a transmission belt, two I-beams, and a transmission assembly. The motor is located on one side of one of the mounting plates, and the two I-beams are respectively fixedly connected to one output end of the motor and one end of the lead screw. The transmission belt is connected to the circumferential surface of the two I-beams, and the transmission assembly is located on one side of one of the mounting plates and is used to drive the take-up roller to rotate.

[0007] Furthermore, the transmission assembly consists of a second gear and a first gear. The first gear is fixedly connected to the circumferential surface of the take-up roller, and the second gear is fixedly connected to another output end of the motor, and the second gear meshes with the first gear.

[0008] Furthermore, a horizontal rod is fixedly connected to the adjacent ends of the two mounting blocks, and a horizontal hole is opened at one end of the mounting block, and the mounting block is slidably connected to the circumferential surface of the horizontal rod through the horizontal hole.

[0009] Furthermore, the circumferential surface of the flat ring is provided with a movable hole, and a movable rod is slidably connected in the movable hole. The upper end of the force plate is fixedly connected to the force plate, and a spring is sleeved on the circumferential surface of the movable rod.

[0010] Furthermore, two external rods are fixedly connected to the circumferential surface of the movable rod, and rollers are rotatably connected to the circumferential surface of both external rods.

[0013] Beneficial effects

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. When it is necessary to wind up the hose, connect one end of the hose to the winding roller, and then start the motor so that its two output ends rotate synchronously. On one hand, one output shaft rotates, and through the meshing of the second gear and the first gear, drives the winding roller to rotate and wind up the hose. On the other hand, the rotation of the other output shaft of the motor, through the transmission of two I-beams and the transmission belt, causes the lead screw to start rotating. Then the lead screw nut connected to the threaded surface of its circumference begins to move horizontally, driving the flattening ring to move on the outside of the winding roller, flattening the hose wound on the circumference of the winding roller, preventing damage caused by hose accumulation, and improving the safety of hose winding. Second, when the screw nut drives the flat ring to move horizontally, it can slide on the circumferential surface of the horizontal rod through the horizontal hole, which improves the horizontal movement stability of the screw nut and the flat ring. When the flat ring moves horizontally, the elastic pull of the spring can pull the force plate down, which in turn pulls the movable rod, the two external rods and the two rollers down to press the hose without damaging the hose, thus improving the stability of the hose when it is wound up.

[0021] In a specific embodiment of this utility model, when it is necessary to wind up the hose, one end of the hose is connected to the winding roller 10, and then the motor 13 is started so that its two output ends rotate synchronously. On one hand, one output shaft rotates, and through the meshing of the second gear 12 and the first gear 11, it drives the winding roller 10 to rotate and wind up the hose. On the other hand, the rotation of the other output shaft of the motor 13, through the transmission of the two I-beams 8 and the transmission belt 9, causes the lead screw 5 to start rotating.

On the other hand, the rotation of the other output shaft of the motor 13, through the transmission of two I-beams 8 and the transmission belt 9, causes the lead screw 5 to start rotating. Then, the lead screw nut 4 connected to the circumferential surface of the lead screw 5 starts to move horizontally, driving the flattening ring 6 to move on the outside of the winding roller 10, flattening the hose wound on the circumferential surface of the winding roller 10, preventing damage caused by hose accumulation, and improving the safety of hose winding.
