Description

Technical Field

[0001] The utility model relates to the technical field of material shaft loading and unloading, in particular to an automatic loading and unloading device for retracting and releasing material shafts in a compound machine. Background Art

[0002] The material shaft is a component in some machines or equipment. It can be used in machines for winding, unwinding or slitting raw materials. The shaft parts that play a specific role are called material shafts.

[0003] Currently, during the production of cigarette liner paper, machine operators must restock or load / unload the base paper after it is used up and the semi-finished product is wound up. To increase the service life of the winding and unwinding shafts and accommodate large-diameter materials, equipment manufacturers design these shafts to be relatively heavy. For example, the winding shaft of a 750S gantry laminating machine weighs 41 kg. This creates significant labor intensity and long hours during daily manual loading and unloading, posing significant safety risks. Furthermore, the slow loading and unloading process also impacts efficiency. Therefore, it is necessary to develop an automated loading and unloading device for the winding and unwinding shafts of laminating machines to address these issues. Utility Model Content

[0021] Example

[0022] See also Figures 1-4 The utility model provides a technical solution: an automatic loading and unloading device for a compound machine's retractable material shaft, comprising a mobile support structure 100 and a loading and unloading structure 200.

[0023] See also Figure 1 and Figure 2 The mobile support structure 100 includes a support frame 110 and a moving member 140 . A top plate 120 and a bottom plate 130 are fixed to the top and bottom of the support frame 110 , respectively. The moving member 140 is installed at the bottom of the support frame 110 .

[0024] A push handle 111 is mounted on one side of the upper end of the support frame 110, and a counterweight 112 is fixed to one side of the lower end of the support frame 110. Pushing the handle 111 facilitates movement of the loading and unloading device, while the counterweight 112 improves the balance of the loading and unloading device. The movable member 140 includes a fixed plate 141 and a connecting rod 142. The fixed plates 141 are symmetrically fixed to the bottom of the support frame 110, and the connecting rod 142 is fixed between the two fixed plates 141. The two ends of the connecting rod 142 are rotatably connected to movable wheels 143. The movable member 140 can be used to facilitate the transfer of the device and improve flexibility.

[0025] See also Figures 1-4 The loading and unloading structure 200 includes a worm gear elevator 210, a loading and unloading sleeve 230, a limiter 240 and an automatic pushing member 250. The worm gear elevator 210 is installed on the top surface of the top plate 120. The output end of the worm gear elevator 210 slides through the top plate 120. The output end of the worm gear elevator 210 is fixed with a connecting frame 220. The loading and unloading sleeve 230 is installed on the connecting frame 220. A notch 231 is formed at one end of the loading and unloading sleeve 230. The limiter 240 is fixed between the top plate 120 and the bottom plate 130. The automatic pushing member 250 is installed on the loading and unloading sleeve 230. The output end of the automatic pushing member 250 extends to the inside of the loading and unloading sleeve 230.

[0026] The loading and unloading sleeve 230 is internally installed with balls 232, which are evenly spaced and distributed in the lower half of the loading and unloading sleeve 230. The balls 232 can reduce friction after the material shaft is inserted, making insertion more labor-saving and convenient. The limiting member 240 includes a sliding sleeve 241 and a limiting rod 242. The sliding sleeve 241 is fixed to the loading and unloading sleeve 230, and the limiting rod 242 slides through the sliding sleeve 241. The limiting rod 242 is fixed between the top plate 120 and the bottom plate 130. The setting of the limiting member 240 here can improve the stability of the lifting and lowering of the loading and unloading sleeve 230. The automatic pushing member 250 includes an electric cylinder 251, which is installed on the top surface of the loading and unloading sleeve 230 through a connecting seat. The output end of the electric cylinder 251 is fixed with a pushing bent rod 252, and the end of the pushing bent rod 252 is fixed with a pushing plate 253. The automatic pushing member 250 can push the material shaft outward, thereby facilitating docking and installation with the equipment.

[0027] Specifically, the working principle of the automatic loading and unloading device for collecting and releasing material shafts is as follows: when in use, the loading and unloading device is moved to the position of the material shaft that needs to be replaced. At this time, the notch 231 is aligned with the bottom of one end of the material shaft, and then the position of the loading and unloading sleeve 230 is adjusted by the worm gear elevator 210 so that the ball 232 at the notch 231 fits with one end of the material shaft. At this time, the loading and unloading device is pushed by pushing the handle 111 to move the material shaft, and the material shaft is inserted into the interior of the loading and unloading sleeve 230. Then, the connection between the material shaft and the equipment is removed. In this way, the transfer of the material shaft can be completed by using the moving part 140. At the same time, when the new material shaft is installed on the equipment, the electric cylinder 251 can be used to drive the pushing bent rod 252 and the pushing plate 253 to push the material shaft out from the interior of the loading and unloading sleeve 230 to complete the loading and unloading operation. In this way, the labor intensity of manual loading and unloading can be reduced during repeated loading and unloading, thereby reducing the generation of safety hazards. At the same time, it is beneficial to increase the speed of loading and unloading, which is beneficial to improve the efficiency of use to a certain extent and more convenient to use.

[0028] It should be noted that the specific model specifications of the worm gear lift 210 and the electric cylinder 251 need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0029] The power supply and principle of the worm gear elevator 210 and the electric cylinder 251 are clear to those skilled in the art and will not be described in detail here.

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
