Description

Technical Field

[0002] At present, during the process of loading the material shaft with materials in the pole piece slitting and coiling process, there are mainly two ways to place the material shaft with materials on the top cone air shaft of the slitter. One way is to use a semi-circular tray trolley for loading. The disadvantage of this way is that when the trolley is pushed to the innermost end, it cannot descend to the lowest height, the loading trolley cannot retreat, the reel is misaligned with the top cone, and two employees are required to assist in pushing the reel on the left and right sides to align the reel with the top cone. There is a great potential safety hazard of pinching hands and crushing feet when using a semi-circular tray trolley for loading. Another way is to use a double-arm trolley for loading. The disadvantage of this way is that the reel and the top cone cannot be aligned at one time, and it is necessary to repeatedly adjust the height, left and right, front and back positions of the loading trolley. During the adjustment process, employees often operate the equipment with one hand and adjust the position of the trolley with the other hand to align the reel with the top cone. There are great safety and quality risks of the pole coil falling and injuring the operator and the coil material being scrapped during the operation process. Content of the Utility Model

[0020] The following will describe in detail the specific implementation mode of the present utility model in conjunction with the attached drawings and preferred embodiments.

[0021] As Figures 1 - 3 shown, an auxiliary loading device for a slitter includes a slitter bottom plate 1 and a top cone air shaft 2 installed thereon. The top cone air shaft is used to fix the material shaft 3. In this device, there are two top cone air shafts, and the two top cone air shafts are respectively installed on the air shaft support 6. The bottom of the air shaft support is connected to the top cone air shaft slide rail 61, and the top cone air shaft slide rail is fixed on the slitter bottom plate. The air shaft support slides on the top cone air shaft slide rail to adjust the distance between the two top cone air shafts so that the two top cone air shafts are applicable to material shafts of different diameters. After adjustment, it is locked with bolts.

[0022] In order to overcome the problems in the background technology, a telescopic hook mechanism 4 and a hook lifting mechanism 5 for coaxially aligning the material shaft with the top cone air shaft are respectively installed on the slitter bottom plate. Through the telescopic hook mechanism 4 and the hook lifting mechanism 5, the position of the material shaft can be accurately adjusted so that the material shaft can be coaxial with the top cone air shaft, facilitating the insertion of the top cone air shaft into the material shaft.

[0023] In this solution, the telescopic hook mechanism can be a transverse movement module that moves horizontally, and a hook is installed at the movable end of the transverse movement module. The hook lifting mechanism can be a longitudinal movement module that moves vertically. The movable end of the longitudinal movement module drives the transverse movement module to move up and down, aligning the material shaft in the hook with the top cone air shaft.

[0024] Specifically, in this embodiment, the telescopic hook mechanism 4 includes a positioning device rotating shaft 41, a positioning device support 42, a hook bearing frame 43, a hook telescopic cylinder 44 and a hook 45. The positioning device supports are two, respectively fixed on both sides of the slitting machine base, and the two ends of the positioning device rotating shaft are connected to the positioning device support through bearings. The hook bearing frames are two, respectively fixed on the positioning device rotating shaft. The hook bearing frames in this embodiment can be adjusted along the axial direction of the positioning device rotating shaft in order to control the distance between the two hooks to adapt to material axes of different sizes. The hook telescopic cylinder is fixed on the hook bearing frame, and the piston rod of the hook telescopic cylinder is fixed with the hook. The hook is provided with a semicircular groove 451, and the material axis can be just placed in the semicircular groove. Furthermore, in order to make the hook run more smoothly, a hook sleeve 46 is fixed on the hook bearing frame, and one end of the hook is connected to a sliding arm 452. The sliding arm and the hook are integral, and its cross-section is I-shaped. The sliding arm is inserted into the hook sleeve and slides with it.

[0025] An embodiment of the hook lifting mechanism 5 is as follows: it includes a lifting cylinder 51, the lifting cylinder is hinged on the bottom plate of the slitting machine, and the piston rod of the lifting cylinder is hinged to the bottom of the hook. The lifting cylinder in this embodiment is fixed and the position cannot be adjusted, that is, the distance between the lifting cylinders is fixed and is only suitable for fixing one type of material shaft.

[0026] As a preferred solution of this embodiment, another embodiment of the hook lifting mechanism is: it includes a lifting cylinder 51, a lifting cylinder connecting block 52 and a lifting cylinder slide rail 53, the lifting cylinder slide rail is fixed on the bottom plate of the slitting machine, the lifting cylinder connecting block is connected to the lifting cylinder slide rail, after the distance adjustment of the lifting cylinder connecting block is completed, the lifting cylinder connecting block is fixed to the lifting cylinder slide rail by tightening bolts, the lifting cylinder is hinged on the lifting cylinder connecting block, and the piston rod of the lifting cylinder is hinged to the bottom of the hook. In order to be suitable for material shafts of different lengths, the hook lifting mechanism is set to an adjustable structure in this embodiment, specifically, the position of the lifting cylinder connecting block is set to be adjustable on the lifting cylinder slide rail, and the telescopic hook mechanism on its upper part also follows the translation to be suitable for material shafts of different sizes.

[0027] In order to make the lifting cylinder connecting block and the air expansion shaft bracket move more smoothly and stably on the corresponding lifting cylinder slide rails and top cone air expansion shaft slide rails respectively, the cross-sections of the lifting cylinder slide rails and the top cone air expansion shaft slide rails are dovetail-shaped, with top screws on the sides to facilitate the positioning and fixation of the upper lifting cylinder connecting block and air expansion shaft bracket.

[0028] Using the new technology of the utility model patent, the employee only needs to operate the equipment to extend the hook to the outside of the bottom plate of the slitter through the hook telescopic cylinder. Use the material transport trolley to place the material shaft and the material 7 into the semi-circular groove of the hook. The hook telescopic cylinder retracts the hook to the position coaxial with the top cone air shaft. At the same time, the lifting cylinder under the hook acts simultaneously to lift the hook to the position coaxial with the top cone air shaft. The top cone air shafts on both sides can accurately insert into the material shaft to complete the feeding work of the slitter. Through this device, the work of the employee repeatedly adjusting the height position of the material shaft is reduced, and the auxiliary operation of pushing and positioning the coil by the employee is reduced. It is safe, convenient, simple and fast.

[0029] It should be pointed out that this device can be used to transport semi-finished lithium batteries, provide vacuum or inert gas according to requirements, and select different accessories for combination to make full use of space and improve work efficiency. For those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and retouches can also be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model.
