Description

Technical Field

[0001] This application relates to the field of winding equipment technology, and in particular to a tarpaulin winding device. Background Technology

[0002] Currently, stacked goods are usually covered with tarpaulins for protection. In order to improve the efficiency of tarpaulin roll-up, movable wheels are fixed to both ends of the roll-up shaft. The movable wheels drive the roll-up shaft to rotate synchronously, thereby rolling the tarpaulin onto the roll-up shaft.

[0003] However, the design of fixing movable wheels to both ends of the winding shaft makes it inconvenient to disassemble the winding shaft, which in turn makes it inconvenient to remove the tarpaulin after winding. Utility Model Content

[0004] The purpose of this application is to provide a tarpaulin winding device, which aims to solve the problem that the winding shaft is inconvenient to disassemble due to the use of fixed moving wheels in the design of the winding shaft in related technologies.

A locking sleeve that screws onto the winding shaft is also provided on the axle.

[0007] The tarpaulin winding device provided in this application embodiment restricts the limiting strip within the limiting groove by screwing the locking sleeve and the winding shaft, which enables the detachable connection between the moving wheel and the winding shaft. Compared with the prior art, it can improve the convenience of disassembling the tarpaulin after it is wound up.

[0008] In some embodiments, the limiting groove is arranged parallel to the axis of the take-up shaft.

[0009] In some embodiments, the limiting grooves are symmetrically arranged at both ends of the take-up shaft.

[0010] In some embodiments, the axle is inserted into the axis of the take-up shaft.

[0011] In some embodiments, the limiting strip is arranged parallel to the axis of the wheel axle.

[0012] In some embodiments, the locking sleeve includes a positioning sleeve and a connecting sleeve. The positioning sleeve is fitted onto the axle inside the limiting strip, and the connecting sleeve is screwed onto the outside of the take-up shaft.

[0013] In some embodiments, the inner diameter of the positioning sleeve is equal to the outer diameter of the axle.

[0014] In some embodiments, the outer diameter of the positioning sleeve is equal to the outer diameter of the winding shaft.

[0015] In some embodiments, the positioning sleeve and the limiting strip are located on the same circumferential surface.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.

[0024] Currently, stacked goods are usually covered with tarpaulins for protection. In order to improve the efficiency of tarpaulin roll-up, movable wheels are fixed to both ends of the roll-up shaft. The movable wheels drive the roll-up shaft to rotate synchronously, thereby rolling the tarpaulin onto the roll-up shaft.

[0025] However, the design of fixing movable wheels to both ends of the winding shaft makes it inconvenient to disassemble the winding shaft, which in turn makes it inconvenient to remove the tarpaulin after winding.

[0026] Based on the above considerations, in order to solve the problem that the design of the winding shaft with fixed moving wheels in related technologies makes it inconvenient to disassemble the winding shaft, a tarpaulin winding device is designed. By screwing the locking sleeve with the winding shaft, the limiting strip is restricted in the limiting groove, which can realize the disassembly and connection of the moving wheel and the winding shaft. Compared with the existing technology, it can improve the convenience of disassembling the tarpaulin after it is rolled up.

[0027] The tarpaulin winding device of the present application embodiment will now be described in detail.

[0028] Please see Figures 1-2This application provides a tarpaulin winding device, including a winding shaft 10 and a movable wheel 20. The axle 21 of the movable wheel 20 is inserted into the winding shaft 10. The axle 21 is provided with a limiting strip 22 that engages with the limiting groove 11 on the winding shaft 10. The axle 21 is fitted with a locking sleeve that screws onto the winding shaft 10.

[0029] The take-up shaft 10 is a long, round rod. In order to connect to the axle 21 of the moving wheel 20, the take-up shaft 10 can be a hollow structure or have insertion holes at both ends.

[0030] The limiting groove 11 is a long rectangular groove, and the limiting groove 11 is arranged parallel to the axis of the take-up shaft 10. The limiting groove 11 is engaged with the limiting strip 22 on the wheel axle 21 to prevent relative rotation between the wheel axle 21 and the take-up shaft 10, and to ensure that the take-up shaft 10 rotates synchronously with the rolling of the moving wheel 20.

[0031] Optionally, the limiting grooves 11 are arranged symmetrically at both ends of the take-up shaft 10.

[0032] In this embodiment, the axle 21 is fixed to the axis of the movable wheel 20 and rotates synchronously with the movable wheel 20. The limiting strip 22 is welded to the outer wall of the axle 21, and the limiting strip 22 is arranged parallel to the axis of the axle 21.

[0033] When the axle 21 is inserted into the axis of the take-up shaft 10 along the axial direction, the limiting strip 22 will be inserted into the limiting groove 11 simultaneously.

[0034] In this embodiment, the locking sleeve includes a positioning sleeve 23 and a connecting sleeve 24. The positioning sleeve 23 is sleeved on the axle 21 inside the limiting strip 22, and the connecting sleeve 24 is screwed onto the outside of the take-up shaft 10.

[0035] The inner diameter of the positioning sleeve 23 is equal to the outer diameter of the axle 21, and the outer diameter of the positioning sleeve 23 is equal to the outer diameter of the winding shaft 10. The positioning sleeve 23 is rotatably fitted onto the outside of the axle 21, so that the locking sleeve can rotate freely around the axle 21.

[0036] As the connecting sleeve 24 continuously rotates forward on the take-up shaft 10, the positioning sleeve 23 will abut against the end of the take-up shaft 10, or the positioning sleeve 23 will abut against the end of the limiting strip 22. At this time, the connecting sleeve 24 reaches the maximum rotation depth on the take-up shaft 10.

[0037] Optionally, the positioning sleeve 23 and the limiting strip 22 are located on the same circumferential surface, the connecting sleeve 24 is sleeved on the outside of the positioning sleeve 23, and the connecting sleeve 24 and the positioning sleeve 23 are welded and fixed together.

[0038] The tarpaulin winding device provided in this application embodiment restricts the limiting strip within the limiting groove by screwing the locking sleeve and the winding shaft, which enables the detachable connection between the moving wheel and the winding shaft. Compared with the prior art, it can improve the convenience of disassembling the tarpaulin after it is wound up.

[0039] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
