Description

Technical Field

[0001] The utility model relates to the technical field of material unloading mechanisms, and more specifically to a pneumatic or motor-driven synchronous unloading and cloth-rolling roller-changing mechanism. Background Art

[0002] The cloth roller is used to roll up the cloth. When working, the cloth roller rotates along the tracks at both ends to roll up the cloth. In the traditional mechanical structure, after the rolling is completed, the fixing device needs to be manually disassembled, and then the material is unloaded and a new cloth roller is added.

[0003] The disadvantages of the current technology that need to be optimized are: it is necessary to manually disassemble the fixing device, unload the material, and then add a new cloth rolling roller, which is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to solve the above technical problems and provide a pneumatic or motor-driven synchronous material unloading and cloth rolling roller replacement mechanism.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A pneumatic or motor-driven synchronous unloading and cloth roll changing mechanism comprises a frame, and a rotating disk, a storage bin, a ramp track groove and a driving device are symmetrically arranged on both sides of the frame;

[0007] The rotating disk is a teardrop-shaped structure, comprising a disk body, an extension portion is provided downward at the bottom of the disk body, the disk body and the extension portion are integrally formed, a material unloading track groove is provided on the extension portion, and a U-shaped groove is provided near the top edge of the disk body;

[0008] The storage bin is fixedly connected to the frame with a slide structure, and the storage bin is tilted. One end of the storage bin at a high position is a feed port for placing spare cloth rolls, and one end of the storage bin at a low position is a discharge port, and a slope track groove is provided at the bottom of the discharge port;

[0009] A rotating disk is provided below the storage bin, the rotating disk is rotatably connected to the frame, and a driving device is installed outside the frame to drive the rotating disk to rotate.

[0010] The driving device is a rotary cylinder or a motor. The output shaft of the rotary cylinder or the motor is fixedly connected to the center of the rotary disk, and the rotary cylinder or the motor is provided to control the precise rotation of the rotary disk.

[0011] The feed port is provided with an upper guide plate and a lower guide plate, and the discharge port is provided with a baffle;

[0012] The slope track groove includes an arc bottom plate and an arc side plate vertically arranged with the arc bottom plate, the arc bottom plate is fixedly connected to the frame and the top end is arranged at the discharge port, and the top end of the arc side plate is fixedly connected to the baffle plate. The upper guide plate and the lower guide plate are arranged in a V shape to expand the width at the feed port for easy feeding. In addition, the arrangement of the lower guide plate can also prevent the spare cloth roll from falling out of the feed port, and the arrangement of the baffle plate is to limit the spare cloth roll to ensure that the spare cloth roll can accurately enter the slope track groove from the discharge port.

[0013] The thickness of the storage bin bottom is consistent with the thickness of the arc bottom plate. It should be noted that the thickness of the storage bin bottom is consistent with the thickness of the arc bottom plate, so that the spare cloth rolling roller can smoothly enter the slope track groove from the discharge port.

[0014] The rotating disk is provided with a plurality of weight-reducing holes.

[0015] The distance between the outer side of the unloading 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 spare cloth rolling roller is d, wherein 0 <H<d,h> d. The bottom of the inner side of the unloading track groove and the support roller are used to pass the spare cloth roll. In order to allow the spare cloth roll to smoothly enter the bottom of the unloading track groove, h must be greater than d, 2-3mm larger. The outer side of the unloading track groove is used to limit the spare cloth roll from falling out of the support roller. Specifically, the spare cloth roll enters the bottom of the through hole from the bottom of the inner side of the unloading track groove. If the impact force is too large, it may rush out of the support roller. Through the design of H, the outer side of the unloading track groove plays a blocking role to prevent the spare cloth roll from falling out.

[0016] In the utility model, a plurality of spare cloth rolling rollers are placed in the storage bin to avoid frequent roller replenishment.

[0017] Working principle: As the cloth rolling roller (the spare cloth rolling roller that enters the work station is the standby cloth rolling roller) rotates, the cloth thickness on the cloth rolling roller increases, which increases the height of the cloth rolling roller shaft. When the cloth rolling roller completes cloth rolling, the cloth is unloaded and the roller is changed. In the specific operation, the driving device drives the unloading track groove to rotate outward, and the cloth rolling roller falls along the unloading track groove and leaves the work station to complete the unloading. The unloading track groove rotates outward and drives the U-shaped groove to rotate at the same time. The spare cloth rolling roller in the U-shaped groove slides down along the slope track groove through rotation, and then leaves the U-shaped groove. Under the action of gravity and inertia, it enters the work station along the slope track groove (the work station is located between the two support rollers and below the unloading track groove) to complete the roller change, and then the rotating disk rotates to make the U-shaped groove return to the discharge port position.

[0018] The beneficial effects of the utility model are as follows:

[0019] The rotary disc is provided with a material unloading track groove and a U-shaped groove. The rotary disc is driven to rotate by a rotating cylinder or a motor to push out the finished cloth roll for unloading. At the same time, the spare cloth roll roller in the U-shaped groove rotates and falls along the slope track groove. Due to the use of a rotary unloading method, the material unloading is smoother, and the spare cloth roll roller rotates and falls, with a low drop height, which has less impact on the cloth rolling mechanism. The two are carried out simultaneously. Compared with the traditional method, it reduces labor hours and greatly improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
