Description

PVC hose production coiling equipment Technical Field

[0001] This utility model relates to the field of pipe winding technology, and in particular to a coiling device for PVC hose production. Background Technology

[0002] After production, PVC hoses are typically wound into coils according to sales specifications for convenient storage and transportation. Existing coiling devices include a horizontally positioned rotating shaft with a horizontally positioned winding drum fixedly mounted on its outer circumference. A first coiling limiter is fixedly mounted at one end of the winding drum, and a second coiling limiter is slidably mounted at the free end of the rotating shaft and locked to the shaft by bolts. The existing coiling device adjusts the width of the coil by adjusting the distance between the first and second coiling limiters. However, after each coil winding, the second coiling limiter must be removed by rotating the bolts before the coil can be removed. Before the next coil winding, the second coiling limiter must be reinstalled and locked with bolts. This repeated disassembly and reassembly of the second coiling limiter is cumbersome and reduces coiling efficiency.

[0003] Therefore, a coiling device for PVC hose production is needed to solve the above problems. Summary of the Invention

[0004] This utility model proposes a coiling device for PVC hose production. The self-locking component enables rapid adjustment and automatic locking of the adjustment sleeve on the drum. Through the cooperation of the drive cylinder and the baffle, the baffle is automatically retracted and automatically unfolded, which facilitates the removal of the coiled hose from the winding drum.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A coiling device for producing PVC hoses includes a frame, on which a horizontally arranged winding drum is rotatably mounted. A coiling limit frame is fixedly mounted at one end of the winding drum near the frame. Several through slots are evenly distributed circumferentially at the free end of the winding drum. A limiting post is fixedly mounted on the inner side of the winding drum. The limiting post is coaxially arranged with the winding drum. An adjusting sleeve is slidably mounted on the limiting post. A first compression spring is provided between the adjusting sleeve and the winding drum. A self-locking component is provided between the adjusting sleeve and the limiting post. Several baffles are hinged to the outer circumferential surface of the adjusting sleeve. The baffles are evenly distributed axially. Several drive cylinders for driving the baffles to retract and unfold are hinged to the outer circumferential surface of the adjusting sleeve.

[0007] As a preferred technical solution, the limiting post is provided with a plurality of positioning peripheral surfaces, wherein the diameter of each positioning peripheral surface near one end of the frame is smaller than the diameter of the other end.

[0008] As a preferred technical solution, the self-locking component includes a locking block hinged to the adjusting sleeve. The locking block includes a limiting end and a reset end. The adjusting sleeve is provided with a relief groove. The limiting end passes through the relief groove and abuts against one of the positioning peripheral surfaces. The adjusting sleeve is provided with a first stop and a second stop. The reset end is located between the first stop and the second stop. A second compression spring is provided between the first stop and the reset end.

[0009] As a preferred technical solution, a plurality of mounting brackets are fixedly installed circumferentially on the outer peripheral surface of the adjusting sleeve. Each mounting bracket is hinged with a baffle. One end of each baffle passes through the corresponding through groove, and the other end of each baffle is hinged to the piston rod of the corresponding driving cylinder.

[0010] As a preferred technical solution, a limiting plate is fixedly installed on each of the mounting brackets. When the baffle extends out of the corresponding through groove and is set perpendicular to the adjusting sleeve, the baffle abuts against the corresponding limiting plate.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] Since the coiling device for PVC hose production includes a winding drum, the distance between the coil limiting frame and the baffle is adjusted through the cooperation of the limiting post, adjusting sleeve, and self-locking component during the use of this device. This allows the device to wind PVC hoses into coils of different widths. After adjusting the distance between the coil limiting frame and the baffle, one end of the PVC hose is fixed to the winding drum. The winding drum rotates, and the PVC hose is wound onto the winding drum. After winding is completed, the baffle rotates to the inside of the winding drum under the drive of the cylinder, allowing the coiled PVC hose to be removed from the winding drum. In this utility model, the cooperation of the limiting post, adjusting sleeve, and locking component allows the adjusting sleeve to be quickly adjusted and automatically locked on the winding drum, thereby realizing the adjustment of the distance between the coil limiting frame and the baffle. Through the cooperation of the driving cylinder and the baffle, the baffle is opened and closed, facilitating the removal of the PVC hose from the winding drum after winding and improving the winding efficiency of the PVC hose.

[0013] Because the coiling device for PVC hose production includes a self-locking component, during the adjustment of the distance between the coiling limit frame and the baffle, pushing the reset end of the locking block moves the limit end away from the positioning circumferential surface, thus releasing the lock of the adjusting sleeve. The adjusting sleeve can then slide on the limit post. After the adjusting sleeve moves to the appropriate position, the locking block is released. Under the action of the second compression spring, the limit end of the locking block abuts against the positioning circumferential surface, and the adjusting sleeve is in a locked state. This achieves rapid adjustment of the distance between the coiling limit frame and the baffle, as well as automatic locking of the adjusting sleeve.

[0014] Since the coiling device for PVC hose production includes a limiting plate, during the use of this device, the driving cylinder drives the baffle to rotate, so that the baffle is set perpendicular to the winding drum, and the baffle abuts against the limiting plate. The setting of the limiting plate limits the baffle. Attached Figure Description
