Description

Technical Field

[0001] The utility model relates to the technical field of material unloading mechanisms, and more specifically to a pneumatic or electric rotating unloading mechanism for a cloth rolling roller. Background Art

[0002] The cloth roller is a mechanism used to roll up and wrap the cloth. The cloth roller rotates along the tracks at both ends to roll up the cloth. After rolling is completed, the volume becomes larger and the weight also increases accordingly. The traditional unloading structure generally uses a linear cylinder or an electric push rod as a drive device to drive the track groove to rotate and unload the cloth. Since the cloth roller fully rolled up is heavier, the reaction force on the drive device is also greater, making the drive device easily damaged.

[0003] For example, a Chinese patent (CN 220617773 U) discloses a cloth unloading device with an automatic unlocking function, including a bracket, a fixed groove, a movable groove, an electric push rod, a cloth winding roller and a supporting roller, the inner walls on both sides of the frame are installed with the fixed grooves, both ends of the roller shaft of the cloth winding roller are respectively installed in cooperation with a fixed groove, the movable groove is arranged at the top of the fixed groove, the upper part of the movable groove is rotatably connected to the frame, an electric push rod is arranged on one side of the movable groove, the base of the electric push rod is hinged to the frame, the piston end of the electric push rod is rotatably connected to the movable groove, and the supporting roller is transmission-connected to the cloth winding roller.

[0004] When the above-mentioned patent is in use, the piston end of the electric push rod extends outward to drive the movable groove to rotate outward to push the cloth winding roller out of the original work station. However, the cloth winding roller full of cloth is relatively heavy, resulting in a relatively large reaction force of the movable groove on the electric push rod. In addition, there is a certain angle between the electric push rod and the movable groove, and the protruding part of the piston end is prone to bend downward and deform, and the welding place between the rotating bearing and the piston end of the electric push rod is prone to cracking under pressure. Utility Model Content

[0005] The purpose of the utility model is to solve the above technical problems and provide a pneumatic or electric rotary unloading mechanism for a cloth rolling roller.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] A pneumatic or electric rotary unloading mechanism for a cloth roll, comprising a frame, a rotary disk and a driving device for driving the rotary disk to rotate;

[0008] There are two rotating disks installed symmetrically on the inside of the frame;

[0009] The driving device is arranged outside the frame;

[0010] A track groove with one end open is arranged at the bottom of the rotating disk.

[0011] The rotating disk is a water drop-shaped structure, and the rotating disk includes a disk body, and an extension portion is provided downward at the bottom of the disk body. The disk body and the extension portion are integrally formed, and the extension portion is provided with the track groove. By designing the extension portion, the bottom of the rotating disk is extended, so that the design of the track groove is reasonably optimized. Specifically, the track groove is used in conjunction with the cloth rolling roller, and the track groove is used to limit the two ends of the cloth rolling roller, while satisfying that the height of the cloth rolling roller continues to rise without being restricted as the thickness of the cloth rolling roller increases. In addition, the length of the track groove should not be too short, otherwise the thickness of the cloth rolling roller will not meet the standard. Therefore, it is the best choice to design an extension portion at the bottom of the disk body to make it a water drop-shaped structure as a whole.

[0012] The rotating disk is provided with a plurality of weight-reducing holes.

[0013] The distance between the outer side of the track groove and the top of the lower support roller is H, the distance between the inner side and the top of the support roller is h, and the diameter of the cloth rolling roller is d, wherein 0 <H<d,h> d. The bottom of the inner side of the track groove and the support roller are used to pass the cloth roller. In order for the cloth roller to smoothly enter the bottom of the track groove, h must be greater than d, 2-3mm larger. The outer side of the track groove is used to limit the cloth roller from falling out of the support roller. Specifically, the cloth roller enters the bottom of the through hole from the bottom of the inner side of the track groove. If the impact force is too large, it may rush out of the support roller. The design of H makes the outer side of the track groove play a blocking role to prevent the cloth roller from falling out.

[0014] The driving device is a rotary cylinder or a motor, which is fixedly mounted on the outside of the frame, and the rotating shaft of the rotary cylinder or the motor passes through the frame and is assembled and connected with the rotating disk.

[0015] When in use, the cloth rolling roller enters under the track groove from the bottom of the inner limiting plate, and the support roller works to increase the thickness of the cloth rolling roller. When the cloth rolling roller needs to be pushed out, the rotating cylinder or motor works to drive the rotating disk to rotate outward, and the cloth rolling roller falls along the track groove and leaves the original work station to complete the unloading.

[0016] The beneficial effects of the utility model are as follows:

[0017] The utility model drives the rotating disk to rotate by a rotating cylinder or a motor so that the cloth winding roller slides down the track groove to discharge the material. The track groove is directly designed on the rotating disk. The rotating disk is directly assembled and connected with the rotating shaft of the driving device, so that the track groove and the driving device do not need to be additionally connected. The structure is more scientific and reasonable. Due to the rotation method, the impact force on the unloading mechanism is smaller and smoother, thereby extending the service life of the unloading mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the length of the track groove 4 is not suitable to be too short, otherwise the thickness of the cloth rolling roller 8 does not meet the standard. Therefore, it is the best choice to design the extension portion 6 at the bottom of the disk body 5 to make it have a water drop-shaped structure as a whole.

[0029] The rotating disk 2 is provided with a plurality of weight-reducing holes 7 .

[0030] The distance between the outer side of the track groove 4 and the top of the lower support roller 9 is H, the distance between the inner side and the top of the support roller 9 is h, and the roller diameter of the cloth rolling roller 8 is d, wherein 0 <H<d,h> d.
