DETAILED DESCRIPTION

[0021] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0022] The embodiment of the present application provides a sheet material winding mechanism, such as Figure 1 As shown, the sheet winding mechanism includes a guide rail 10, a winding device 20, and a drive device 30. The guide rail 10 is arranged on the ground and extends in the front-to-back direction. The drive device 30 is fixedly mounted on the ground behind the guide rail 10. The winding device 20 can move backward along the guide rail 10 to precisely mate with the drive device 30, and the sheet is wound under the drive of the drive device 30.

[0023] The winding device 20 includes a mobile frame 1, an inflatable shaft 2 rotatably mounted on the mobile frame 1, and a mobile wheel group 3 and a caster group 4 mounted at the bottom of the mobile frame 1. The inflatable shaft 2 extends in the front-to-back direction. When the inflatable shaft 2 rotates around its own axis on the mobile frame 1, the sheet is wound.

[0024] The mobile frame 1 includes a base 11 and a first support column 12 and a second support column 13 arranged opposite to each other in the front and rear directions. The first support column 12 is located in front of the second support column 13. The first support column 12 and the second support column 13 both extend in the up and down directions. The first support column 12 is fixedly installed on the upper side of the front end of the base 11, and the second support column 13 is fixedly installed on the upper side of the rear end of the base 11.

[0025] like Figure 1 、 2As shown, the moving wheel group 3 and the caster group 4 are both installed at the bottom of the base 11 and are installed in a staggered manner with respect to each other. The moving wheel group 3 includes a plurality of moving wheels 31 rotatably arranged at the bottom of the base 11, and each moving wheel 31 can cooperate with the guide rail 10. The axis of each moving wheel 31 extends in the left-right direction, and each moving wheel 31 has a circle of annular grooves that are radially concave inward around the axis. The guide rail 10 has an upwardly protruding protrusion, and the annular grooves cooperate with the protrusions, so that the winding device 20 can move back and forth in the front-back direction along the guide rail 10 through the moving wheel group 3, thereby preventing the winding device 20 from deviating from the moving direction on the guide rail 10. The winding device 20 has a winding position on the guide rail 10 that is docked with the drive device 30 and an unwinding position that is disengaged from the drive device 30. The winding device 20 moves between the winding position and the unwinding position through the moving wheel group 3.

[0026] The caster assembly 4 includes a plurality of casters 41 rotatably mounted on the bottom of the base 11. The diameter of the movable wheel 31 is larger than the diameter of the casters 41, and the lower end of each movable wheel 31 is located above the lower end of each caster 41. When the movable wheels 31 of the movable wheel assembly 3 are engaged with the guide rail 10, the casters 41 of the caster assembly 4 are suspended above the ground, and the winding device 20 moves on the guide rail 10 via the movable wheel assembly 3. When the casters 41 of the caster assembly 4 are in contact with the ground, the movable wheels 31 of the movable wheel assembly 3 are suspended above the ground, and the winding device 20 is flexibly moved on the ground via the caster assembly 4. The winding device 20 of the present application adopts two mobile mechanisms to support movement, one is a mobile wheel group 3 that moves on the guide rail 10 to ensure that the winding device 20 is docked with the driving device 30, and the other is a caster group 4 that enables the winding device 20 to move freely on the ground. Under the action of the two mobile components, the winding device 20 is wound in a fixed area and then moved freely to other areas for unloading. The mobile wheel group 3 can improve the accuracy of the docking of the winding device 20 with the driving device 30, and the caster group 4 can improve the flexibility of the unloading area selection, which can meet different production environments.

[0027] The front end of the guide rail 10 is a slope that gradually tilts upward from front to back, which facilitates the movement of the movable wheel group 3 on and off the guide rail 10, and facilitates the transition between the movable wheel group 3 and the caster group 4; a blocking block is arranged at the rear end of the guide rail 10 to prevent the winding device 20 from moving too far backward and falling off the guide rail 10.

[0028] The winding device 20 also includes a first mounting seat 5 and a second mounting seat 6 that are arranged relative to each other in the front and rear directions. The first mounting seat 5 is located in front of the second mounting seat 6. The first mounting seat 5 is fixedly mounted on the top end of the first support column 12, and the second mounting seat 6 is fixedly mounted on the top end of the second support column 13. A mounting chuck 7 is respectively arranged on the first mounting seat 5 and the second mounting seat 6. The two ends of the inflatable shaft 2 are respectively matched with a pair of mounting chucks 7, so that it can be rotatably mounted on the movable frame 1 around its own axis.

[0029] A handle 8 for an operator to hold is installed at the front end of the moving mechanism 1. The handle 8 is convenient for the operator to push the winding device 20 to move.

[0030] The driving device 30 is on the rear side of the guide rail 10. When the winding device 20 moves to the winding position on the guide rail 10, the driving device 30 can dock with the winding device 20, thereby driving the inflatable shaft 2 to rotate around its own axis to wind the sheet. When the winding device 20 moves to the unwinding position on the guide rail 10, the driving device 30 disengages from the winding device 20, and the winding device 20 moves down from the guide rail 10 and then moves to the unwinding area through the caster group 4.

[0031] A detachable coupling 9 is connected between the reel 20 and the drive unit 30. The detachable coupling 9 includes a first portion 91 coaxially arranged with the output shaft of the drive unit 30 and a second portion 92 coaxially arranged with the mounting chuck 7 on the second mounting seat 6. The first portion 91 and the second portion 92 are configured to engage with each other, allowing the drive unit 30 to drive the pneumatic shaft 2 to rotate via the detachable coupling 9. The reel 20 and the drive unit 30 are configured as a detachable structure, so that the reel 20 does not need to carry the drive unit 30 when moving to the unloading area, reducing the operator's burden on the transport and saving time and effort.

[0032] The present application has a movable wheel set that ensures the docking of the winding device with the driving device and a caster set that enables the winding device to move freely on the ground. The detachable structure between the winding device and the driving device improves the flexibility of the unloading area selection and can meet different production environments.

[0033] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments. The above embodiments and descriptions are only for illustrative purposes. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application. The scope of protection claimed in the present application is defined by the appended claims, the description and their equivalents.
