Description

Technical Field

[0001] The utility model relates to the technical field of differential slip shafts, in particular to a differential slip shaft for a slitting machine. Background Art

[0002] The slitting machine is a device that cuts a roll of web material into multiple rolls, and it is widely used. The function of the reel is to wind the multiple rolls of various materials into strips, from the core to the outer layer, evenly, neatly, and with constant tension on one or two shafts. However, due to the uneven thickness of the material itself, there is a certain thickness error. After the rolls are continuously wound, the diameters of each roll have a larger accumulated error. This leads to a greater difference in the winding speed and tension of each strip of material. The rolls are uneven in tightness and the end faces are uneven. In severe cases, the material is damaged and scrapped due to excessive tension, especially polyester film, which not only has a large thickness error, but also has a large elongation, and is easily stretched and deformed to cause waste.

[0003] The slip shaft, also known as the friction shaft, is used for the reel shaft of the slitting machine and is also used for the unwinding shaft in special occasions. The purpose is to use the principle of slipping of each slip ring on the slip shaft to make multiple rolls on the shaft always maintain constant tension for rewinding and unwinding. The slip shaft has a special structure, mainly composed of multiple slip rings, which can overcome the above phenomenon.

[0004] However, the force on the tension rewinder of the slip shaft is currently unstable, and it is not convenient to disassemble and add materials. Since the materials on it need to be added or replaced, the staff need to use tools to disassemble it and put the materials on the shaft body, which reduces work efficiency and increases the workload of the staff.

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0023] like Figures 1 to 6 A differential shaft for a slitting machine is shown, characterized in that it comprises: a main shaft body 1, inner rings 2 are movably sleeved at intervals on the main shaft body 1, differential rings 3 are movably sleeved on each of the inner rings 2, multiple lock pins 4 are inserted at intervals on each of the differential rings 3, mounting parts 5 are provided on the left and right sides of the main shaft body 1, a moving mechanism 100 that can drive the lock pins 4 to move up and down is provided on each of the inner rings 2, and a fixing mechanism 200 and a locking mechanism 300 are respectively provided on each of the mounting parts 5.

[0024] The slip shaft of the above structure for a slitting machine is installed on the production equipment through the mounting part 5 when in use. At this time, the main shaft body 1 and the mounting part 5 are separated by the locking mechanism 300 and the fixing mechanism 200. The user takes down the main shaft body 1 and places the material. During operation, the main shaft body 1 rotates clockwise, so that the main shaft body 1 drives the inner ring 2 to rotate. At this time, the inner ring 2 drives each locking column 4 to move upward through the moving mechanism 100, so that the locking column 4 fixes the material on the slip ring 3. Compared with the existing technology, the tension of the slip shaft can be evenly retracted and unreeled, and the material thereon can be easily added or replaced.

[0025] like Figure 4 and 5As shown, in some embodiments of the utility model, the mounting portion 5 includes mounting seats 51 arranged on the left and right sides of the main shaft body 1, a plug-in shaft 53 is fixed on the left side of the main shaft body 1, a plug-in hole 54 for plugging the plug-in shaft 53 is provided in the middle of one of the mounting seats 51, a locking hole 55 is provided on the right side of the main shaft body 1, a guide groove 56 is provided in the middle of another mounting seat 51, and a locking shaft 57 is movably plugged in the guide groove 56. The user installs each of the mounting seats 51 on an external rotating motor and a support respectively, and the main shaft 1 is plugged into the plug-in hole 54 in the middle of one of the mounting seats 51 through the plug-in shaft 53, and a locking shaft 57 is provided in the guide groove 56 in the middle of the other one, and the locking shaft 57 moves along the guide groove 56 through the locking mechanism 300, so that the locking shaft 57 is plugged in the locking hole 55, and the plug-in shaft 53 is fixed to one of the mounting seats 51 through the fixing mechanism 200.

[0026] like Figure 6 As shown, in some embodiments of the utility model, the moving mechanism 100 includes a slide groove 101 arranged on the left and right sides of each inner ring 2, and an inclined surface 102 is fixed at intervals in each slide groove 101, and a plane 103 is connected to one side of each inclined surface 102, and the inclined surface 102 and the plane 103 are magnetic, and the lock column 4 is arranged in the slide groove 101 below.

[0027] When a differential shaft used in a slitting machine using the above structure is in operation, when the main shaft body 1 rotates clockwise during use, the main shaft body 1 drives the inner ring 2 to rotate, and the slide grooves 101 on the left and right sides of the main shaft body 1 rotate accordingly, and at the same time, the inclined surface 102 fixed in the slide groove 101 moves accordingly. While the inclined surface 102 moves, since the differential ring 3 is in a stationary state, the lock column 4 thereon contacts the inclined surface 102, and the lock column 4 gradually moves upwards until it moves to the plane 103, so that the lock column 4 is stuck in the inner member of the material, and when the main shaft rotates counterclockwise, since the inclined surface 102 and the plane 103 are magnetic, the lock column 4 gradually moves downwards with the inclined surface 102.

[0028] like Figure 4 As shown, in some embodiments of the utility model, the fixing mechanism 200 includes a card slot 201 arranged on the upper and lower sides of the plug-in shaft 53, a through slot 202 is penetrated on one of the mounting seats 51, a card block 203 is symmetrically and movably inserted on the through slot 202, and the card block 203 is inserted in the card slot 201, and a C-shaped slot 204 that can communicate with the through slot 202 is provided on the rear side of one of the mounting seats 51, and a C-shaped plate 205 is inserted on the C-shaped slot 204.

[0029] When a slip shaft used in a slitting machine using the above structure is in operation, the user covers the C-shaped plate 205 on the C-shaped groove 204, so that the C-shaped plate 205 presses each block 203 into the groove 201, and the block 203 moves along the through groove 202. Finally, the user fixes the C-shaped plate 205 and the C-shaped groove 204 to each other with screws.

[0030] like Figure 4 and 5 As shown, in some embodiments of the present invention, the locking mechanism 300 includes a motor 301 fixed to the right side of another mounting seat 51, a screw 302 is provided at the output end of the motor 301 and arranged in the guide groove 56, a screw hole 303 is provided in the middle of the lock shaft 57, and the screw 302 and the screw hole 303 are threadedly matched with each other.

[0031] When a slip shaft for a slitting machine using the above structure is in operation, the motor 301 is driven by a power source, so that the motor 301 drives the screw 302 to rotate. While the screw 302 rotates, the lock shaft 57 is driven to move along the guide groove 56 through the screw hole 303, so that the lock shaft 57 and the lock hole 55 are separated.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
