Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a surface winding type slitting machine. Background Art

[0002] The roll-up slitting machine is a device specially used for slitting rolls, which is widely used in paper, plastic, rubber, textile and other industries. It takes the roll-up method, takes the roll off the reel, cuts it through the slitting device, and then reels the cut roll onto the reel. This is the working principle of the surface roll-up slitting machine.

[0003] In the prior art, such winding-type slitting machines can generally adjust the spacing of the cutting knives as needed during operation, but it is more troublesome to increase the number of cutting knives. For example, a surface winding-type slitting machine disclosed in Chinese patent application No. 201821129605.0 can only be used to disassemble the cutting knives when the number of cutting knives is changed during use (that is, some cutting knives are not involved in the work), which is more troublesome. Therefore, an improved surface winding-type slitting machine is needed to address this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a surface winding type slitting machine to solve the problems raised in the above background technology.

[0005] The slitting machine according to claim 1, wherein the lifting of the rollers is rotatable and the lifting of the rollers are performed along the length of the slitting plate to move the rollers upwardly and downwardly. The slitting mechanism comprises a guide rail, a fixed frame, a slot, a slide block, a rotating block, a cutting knife, and a screw. The guide rail is fixedly arranged between the upper ends of the side plates, and a fixed frame is arranged between the slide rails. The fixed frame has slots on both sides of the surface of the fixed frame. The fixed frame is movably engaged with the outer surface of the slide rail through the slot, and a slide groove is arranged in the middle of the surface of the fixed frame. A slide block is movably engaged with the inside of the slide groove, and a rotating block is movably arranged in the middle of the surface of the slider through the rotating shaft. The cutting knife is arranged on the outer surface of the rotating block, and a screw is movably screwed with a thread in the middle of the inner side of the fixed frame.

[0006] Preferably, a hand wheel is fixedly provided on the upper end of the screw rod, and the screw rod can be conveniently rotated by the hand wheel.

[0007] Preferably, a first locking screw is provided between the cutting blade and the rotating block, and the cutting blade can be conveniently fixed by the first locking screw, and can also be conveniently and quickly disassembled and replaced when the cutting blade needs to be replaced.

[0008] Preferably, both sides of the upper end of the fixed frame are provided with second locking screws through threaded engagement. The second locking screws of the device can penetrate into the slot position. When the fixed frame is sleeved on the outer surface of the slide rail through the slot; when the fixed frame moves to the target, tighten the second locking screw, which will be squeezed with the slide rail, and then use this friction force to fix the fixed frame and the cutting knife position.

[0009] Preferably, a notch is provided on one side of the surface of the slide rail. Figure 1 As shown, the notch is opened at the very edge of the slide rail, and because this position is relatively close to the edge, it will not affect the slitting work; when the slitting mechanism needs to be disassembled, the fixed frame is slid to the notch position, and the slitting mechanism can be disassembled. Similarly, when the slitting mechanism needs to be installed, the notch can be used to slide in and install the slitting mechanism, so that the number of slitting mechanisms can be changed.

[0010] Preferably, the lower end of the screw is movably connected to the slider via a bearing, and the screw and the slider are connected via the bearing, so that the screw can rotate relative to the slider, but cannot be displaced relative to the slider. Rotating the screw by the thread can drive the slider to move up and down under the action of the thread.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. Whether the cutting knife of the utility model participates in cutting can be determined by rotating the screw rod through the thread. When the screw rod moves up, it drives the slider to move up, so that the cutting knife is away from the material on the upper end of the transmission roller. In this way, the number of cutting knives participating in the cutting work can be changed conveniently and quickly, so that the whole piece of material can be conveniently cut into a predetermined number.

[0013] 2. When the utility model is used, a notch is provided at the edge of the slide rail, and since this position is relatively close to the edge, it will not affect the slitting work; when the slitting mechanism needs to be disassembled, the fixed frame is slid to the notch position, and the fixed frame part can be disassembled. Similarly, when the slitting mechanism needs to be installed, the notch can be used to slide in and install the slitting mechanism, so that the number of slitting mechanisms can be changed.

[0014] 3. Each cutting structure of the utility model exists independently, and each cutting knife will not interfere with each other. When a cutting knife is damaged, the first locking screw can remove the cutting knife, so that the cutting knife can be easily replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 The utility model provides a technical solution: a surface winding slitting machine, comprising a side plate 1, a transmission roller 2 is movably arranged between the side plates 1 through a rotating shaft, two transmission rollers 2 are provided, and are symmetrically arranged on both sides between the side plates 1, and a slitting mechanism for cutting materials is arranged on the upper end of the side plate 1, and the slitting mechanism includes a slide rail 3, a fixed frame 4, a card slot 5, a slide groove 6, a slider 7, a rotating block 8, a cutting knife 9, and a screw 10. A slide rail 3 is fixedly arranged between the upper ends of the side plates 1, a fixed frame 4 is arranged between the slide rails 3, and card slots 5 are opened on both sides of the surface of the fixed frame 4, and the fixed frame 4 is movably engaged with the outer surface of the slide rail 3 through the card slot 5, and a slide groove 6 is opened in the middle of the surface of the fixed frame 4, and a slider 7 is movably engaged with the inside of the slide groove 6, and a rotating block 8 is movably arranged in the middle of the surface of the slider 7 through a rotating shaft, and a cutting knife 9 is arranged on the outer surface of the rotating block 8, and a screw 10 is movably screwed in the middle of the inner side of the fixed frame 4 through a thread.

[0021] A hand wheel 11 is fixedly provided at the upper end of the screw rod 10, and the screw rod 10 can be conveniently rotated by the hand wheel 11;

[0022] A first locking screw 12 is provided between the cutting blade 9 and the rotating block 8, and the cutting blade 9 can be conveniently fixed by the first locking screw 12, and the cutting blade 9 can also be conveniently and quickly disassembled and replaced when it is necessary to replace the cutting blade 9;

[0023] The second locking screws 13 are provided on both sides of the upper end of the fixed frame 4 through threaded engagement. The second locking screws 13 of the device can penetrate into the position of the card slot 5. When the fixed frame 4 is sleeved on the outer surface of the slide rail 3 through the card slot 5; when the fixed frame 4 moves to the target, tighten the second locking screws 13, which will be squeezed with the slide rail 3, and then use this friction force to fix the fixed frame 4 and the cutting knife 9.

[0024] A notch 14 is provided on one side of the surface of the slide rail 3. Figure 1 As shown, the notch 14 is provided at the very edge of the slide rail 3, and since this position is relatively close to the edge, it will not affect the slitting work; when the slitting mechanism needs to be disassembled, the fixed frame 4 is slid to the position of the notch 14, and the slitting mechanism can be disassembled. Similarly, when the slitting mechanism needs to be installed, the notch 14 can be used to slide in and install the slitting mechanism, so that the number of slitting mechanisms can be changed;

[0025] The lower end of the screw rod 10 is movably connected to the slider 7 via a bearing. The screw rod 10 and the slider 7 are connected via a bearing so that the screw rod 10 can rotate relative to the slider 7, but cannot be displaced relative to the slider 7. Rotating the screw rod 10 through the thread can drive the slider 7 to move up and down under the action of the thread.

[0026] Working principle: When the device is used, the transmission roller 2 is used to transmit and support the material to be cut; at this time, the material on the upper end of the transmission roller 2 can be cut by the cutting knife 9, and whether the cutting knife 9 participates in the cutting can be determined by rotating the screw rod 10 through the thread. When the screw rod 10 moves upward, the slider 7 moves upward, so that the cutting knife 9 is away from the material on the upper end of the transmission roller 2. In this way, the number of cutting knives 9 participating in the cutting work can be changed conveniently and quickly, so that the whole piece of material can be conveniently cut into a predetermined number;

[0027] As for the positions of the fixed frame 4 and the cutting knife 9, since the fixed frame 4 is sleeved on the outer surface of the slide rail 3 through the card slot 5, the fixed frame 4 can slide freely along the slide rail 3 until it is suitable; when the fixed frame 4 moves to the target, tighten the second locking screw 13, which will be squeezed with the slide rail 3, and then use this friction force to fix the position of the fixed frame 4 and the cutting knife 9; in this way, the spacing of the cutting knife 9 can be adjusted;

[0028] When the device is used, a notch 14 is provided at the edge of the slide rail 3, and since this position is close to the edge, it will not affect the slitting work; when the slitting mechanism needs to be disassembled, the fixed frame 4 is slid to the notch 14 position, and the fixed frame 4 can be partially disassembled. Similarly, when the slitting mechanism needs to be installed, the notch 14 can be used to slide in and install the slitting mechanism, so that the number of slitting mechanisms can be changed;

[0029] Furthermore, when the device is used, each cutting structure exists independently, and each cutting blade 9 will not interfere with each other. When a cutting blade 9 is damaged, the first locking screw 12 can remove the cutting blade 9, thereby facilitating the replacement of the cutting blade 9.
