Description

Technical Field

[0001] This utility model relates to the field of hose production equipment technology, and in particular to a PVC fiber reinforced hose coil winding device. Background Technology

[0002] PVC fiber-reinforced hoses are important fluid transport pipes widely used in industry, agriculture, construction, and household applications. These hoses mainly consist of an inner PVC pipe body, a middle fiber reinforcement layer, and an outer PVC protective layer, with the fiber reinforcement layer being the key structure for pressure resistance. PVC fiber-reinforced hoses offer advantages such as light weight, corrosion resistance, good flexibility, high pressure resistance, and long service life, making them widely used for transporting various media including water, oil, gas, and chemicals.

[0003] Existing technology, patent CN218860015U, discloses a coiling machine for producing plastic hoses, including a placement plate. Support plates are respectively arranged on both sides of the surface of the placement plate. A second motor is arranged on one side of the top of the support plate, and the output end of the second motor is connected to a rotating shaft. One end of the rotating shaft is sleeved with a coiling frame. An electro-hydraulic push rod is arranged on the other side of the top of the support plate. The machine operates a first motor, which drives a moving block to reciprocate via a threaded rotating shaft. The moving block drives a guide ring to reciprocate, which in turn moves the hose, allowing the hose to be evenly wound around the surface of the coiling frame, thus increasing the coiling effect. Furthermore, the spring force drives a pressure plate to move, bringing the pressure plate closer to the coiling frame to compress the hose, preventing loosening and improving the coiling effect.

[0026] In use, the worker first places the hose 4 from the storage bin 3 onto the support roller 156 in the conveying mechanism 15, then inserts the hose 4 into the gap between the five conveying rollers 154 arranged vertically, through the guide groove 159, and finally fixes it in the snap ring 111 of the coil frame 11. The second motor 10 is then turned on, and its output shaft drives the transmission shaft 7 at the first bracket 5 to rotate. The striped protrusions on the transmission shaft 7 mesh with the grooves at both ends of the coil frame 11, causing the transmission shaft 7 to drive the coil frame 11 to rotate synchronously. The coil frame 11 then drives the hose 4, which is snapped in place by the snap ring 111, to rotate, allowing the hose 4 to wrap around the outer wall of the coil frame 11. At this time, the first motor 91 is turned on, and its output shaft drives the reciprocating screw 93 to rotate. The rotation of rod 93 drives nut 151 to move to the left in the horizontal direction. Nut 151 drives conveying mechanism 15 to move synchronously, so that hose 4 can be evenly wound on coil rack 11. As coil rack 11 rotates, when hose 4 is wound on coil rack 11 for the first layer and the first turn, the first turn of hose 4 contacts the arc edge set on the top right side of extrusion block 144. As hose 4 continues to wind, hose 4 squeezes extrusion block 144 and gradually moves to the left. Extrusion block 144 drives main drive rod 141 to move synchronously under the limit of driven ring 142 and guide rod 13. Extrusion block 144 gives hose 4 a reaction force. At the same time, main drive rod 141 is subjected to lateral friction force from guide rod 13 on the inner wall of long arc groove, so that each turn of hose 4 can fit tightly without gaps. When main drive rod 141 When the conveying mechanism 15 moves to the leftmost side of the slot opened in the guide plate 12, the first layer of hose 4 has not yet been wound. The conveying mechanism 15 continues to move to the left. At this time, the right arc edge of the extrusion block 144 disengages from the penultimate loop of hose 4, and the top arc edge of the extrusion block 144 contacts and squeezes the hose 4. The extrusion block 144 is squeezed in the opposite direction by the hose 4, causing the extrusion block 144 to squeeze the main drive rod 141 and the second spring 143 and move diagonally downward. When the conveying mechanism 15 moves to the leftmost end of the reciprocating screw 93, the last loop of hose 4 is wound on the coil rack 11. The last loop of hose 4 disengages from the top arc edge of the extrusion block 144 and contacts the left side of the extrusion block 144. The top arc edge of the extrusion block 144 no longer contacts and squeezes the hose 4, and the extrusion block 144 no longer squeezes the main drive rod 141. Rod 141 and the second spring 143 return to their original deformation. The extrusion block 144 and the main drive rod 141 move obliquely upwards. At this time, the hose 4 is positioned to the left of the extrusion block 144 and contacts the left arc edge of the extrusion block 144. The height of the extrusion block 144 is slightly higher than the initial height due to the pressure of the second-to-last turn of the hose 4 on the top arc edge of the extrusion block 144. Meanwhile, the coil rack 11 continues to rotate, and the hose 4 begins winding from the first turn of the second layer on the leftmost side of the coil rack 11. At this time, the hose 4 is to the left of the extrusion block 144, pressing against the top arc edge of the left side of the extrusion block 144. The extrusion block 144 moves obliquely downwards and presses the second spring 143. The main drive rod 141 moves obliquely downwards synchronously with the extrusion block 144. When the first turn of the second layer is completed...The conveying mechanism 15 moves to the right along the reciprocating screw 93. At this time, the hose 4 begins to wind to the right and squeezes the extrusion block 144 to move to the right. The extrusion block 144 gives the hose 4 a leftward reaction force, so that each turn of the second layer of the hose 4 can be tightly connected, and the second layer of hose 4 can be in closer contact with the first layer of hose 4. This process continues until all the hoses 4 are wound on the coil rack 11. The worker turns off the first motor 91 and the second motor 10, wraps the wound hoses 4 with plastic film, and then presses down the slide rod 174. The third spring 175 is compressed, and the cross protrusion of the second locking block 176 slides against the cross groove 173 opened in the hollow rod 171, so that the second locking block 176 approaches and contacts the first locking block 172. At this time, the top of the second locking block 176... The limiting blocks 63 on both sides are pressed and squeezed, causing the limiting blocks 63 on both sides to move away from the support column 62. The limiting blocks 63 compress the first spring 64. When the second locking block 176 is fully in contact with the first locking block 172, the limiting blocks 63 on both sides are fully opened. The inclined surface of the second locking block 176 contacts the limiting blocks 63 on both sides. The worker pulls the hollow rod 171, causing the inclined surface of the second locking block 176 to press the limiting blocks 63 on both sides. The second locking block 176 pulls the first locking block 172 out of the arc groove 65. At this time, the first spring 64 returns to its original deformation, causing the limiting blocks 63 on both sides to return to their initial position. At this time, the limiting blocks 63 on both sides no longer limit the first locking block 172. The slide groove 16 is no longer fixed to the moving frame 66 by the fixing mechanism 17. It is hinged to the sleeve 21 through the pin 161. Open the slide groove 16 to change it from a vertical to a horizontal state. At this time, pull the moving frame 66 away from the coil rack 11. The two sliders 61 at the bottom of the moving frame 66 move within the square groove 22 and the slide groove 16. The stripes on the drive shaft 7 on one side of the moving frame 66 no longer engage with the coil rack 11. At the same time, the worker removes the coil rack 11 with the hose 4 wound around it from the drive shaft 7 at the first support 5 and places it in the desired position. It is worth noting that when the moving frame 66 moves along the slide groove 16, the coil rack 11 disengages from the drive shaft 7 on one side of the moving frame 66. Since the drive shaft 7 at the first support 5 still provides some fixation for the coil rack 11, and the worker holds the coil rack 11 with his hand while pulling the moving frame 66 away, the coil rack 11 does not... It will not fall off. After removal, a new coil holder 11 is reinstalled on the drive shaft 7 at the first bracket 5. The moving frame 66 is pushed so that its bottom slider 61 moves to the square groove 22 and returns to its initial position. The other end of the new coil holder 11 engages with the drive shaft 7 at the moving frame 66. At this time, the slide 16 is closed, and the slide 16 changes from a horizontal state to a vertical state. The hollow rod 171 is pressed, and the first locking block 172 contacts and squeezes the two side limiting blocks 63. The first spring 64 is compressed. When the first locking block 172 no longer squeezes the two side limiting blocks 63, the two side limiting blocks 63 are now located between the first locking block 172 and the second locking block 176. The hollow rod 171 is no longer pressed, the first spring 64 returns to its deformation, and the limiting blocks 63 limit the first locking block 172 again.The first locking block 172 limits the vertical position of the slide 16, which in turn fixes the movable frame 66, awaiting the start of the next hose winding operation.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
