Description

Technical Field

[0001] This utility model relates to a slitting device. Background Technology

[0002] In the field of household paper products, continuous products need to be cut into independent products. For example, in the manufacturing process of sanitary napkins / diapers / disposable pads, continuous sheets need to be cut into independent sanitary napkins / diapers / disposable pads.

[0003] Existing slitting equipment includes a slitting device and conveyor devices located on both sides of the slitting device, used to convey materials to the slitting device and convey the slitting material, respectively. During operation, the conveyor devices on both sides of the slitting device have different conveying speeds; the conveyor device on the faster side independently and quickly conveys the slitting products to the downstream process. However, when the slitting device fails to slit a product, the conveyor device on the faster side will pull upstream material continuously into the slitting device, causing material blockage at the slitting device and thus affecting production efficiency.

[0004] To address material blockage, CN212471711U discloses a slitting device that reduces the risk of material blockage by installing a stop device on the conveying device. In the event of blockage, the conveying device can be stopped in time, facilitating the cleaning of accumulated material and improving process efficiency.

[0005] This method is suitable for conveying devices with pressure conveying units. However, it cannot be applied to situations where pressure conveying is not required or where pressure conveying units cannot be installed. Therefore, there is a need to provide a slitting device with a wider range of applications. Utility Model Content

Detailed Implementation

[0018] Please refer to the reference. Figures 1-4 This utility model provides a slitting device, including a slitting component 10 and a conveying device.

[0019] The slitting component 10 is used to cut continuous materials to be slitted into independent products. In this embodiment, the slitting component 10 includes a cutting roller 11 and a bottom roller 12. A plurality of cutting blades are provided on the cutting roller 11. At the same time, a gap 13 is included between the cutting roller 11 and the bottom roller 12. When the materials to be slitted enter the gap 13, they are cut into independent products by the cutting blades. It can be understood that the products can be sanitary napkins, diapers, disposable nursing pads, etc., which will not be described in detail here.

[0020] The conveying device is configured upstream or downstream of the slitting assembly 10, and is used to convey the material to be slitted to the slitting assembly 10, or to convey the slitting product to the downstream direction. In this embodiment, the conveying device includes a first conveying device 20 disposed upstream of the slitting assembly 10 and a second conveying device 30 disposed downstream of the slitting assembly 10. Meanwhile, the structure of the second conveying device 30 is basically the same as that of the first conveying device 20. In the following description, only the first conveying device 20 will be described in detail, and the second conveying device 30 will not be described in detail.

[0021] In addition, the movement speed of the second conveying device 30 is configured to be greater than that of the first conveying device 20. By utilizing the speed difference between the second conveying device 30 and the first conveying device 20, the second conveying device 30 can separate the products formed by the cutting by a certain interval, so that each product is independent of each other and has a certain interval, so as to facilitate the operation and processing of subsequent processes.

[0022] The first conveying device 20 includes a fixed part 21, a movable part 22, and an actuating element 23 disposed between the fixed part 21 and the movable part 22.

[0023] The movable part 22 includes a first idler roller 201 adjacent to the slitting assembly 10, and the fixed part 21 includes a second idler roller 202 away from the slitting assembly 10. The conveying device also includes a conveyor belt 204 sleeved on the first idler roller 201 and the second idler roller 202, forming a support surface 2040 between the first idler roller 201 and the second idler roller 202. The actuating element 23 is configured to drive the movable part 22 to move as a whole toward or away from the slitting assembly 10. This movement of the movable part 22 toward or away from the slitting assembly 10 causes the first idler roller 201 to move synchronously toward or away from the slitting assembly 10, thereby adjusting the first idler roller. The position between the first roller 201 and the gap 13 ensures that the material to be cut can stably enter the gap 13. Secondly, when the first roller 201 moves away from the gap 13, the material no longer enters the cutting assembly 10, thereby stopping the feeding and preventing material blockage. Thirdly, the actuating element 23 is arranged between the movable part 22 and the fixed part 21, so that the movable part 22 can have a larger movement distance, so that even if material blockage occurs, it can be easily cleared. In addition, the first roller 201 can be further configured to completely detach from the cutting assembly 10, thereby facilitating the disassembly of the cutting assembly 10. Furthermore, the movement distance of the movable part 22 is greater than or equal to 150 mm, more preferably, the movement distance of the movable part 22 is greater than or equal to 200 mm, or further greater than or equal to 300 mm.

[0024] Specifically, the movable part 22 includes a first frame 2201, and the first roller 201 is disposed at one end of the first frame 2201 facing the cutting assembly 10. The first frame 2201 includes a base plate 2202 and a front side plate 2203. The front side plate 2203 faces the fixed part 21 and is connected to the actuating element 23. When the actuating element 23 moves, it drives the first frame 2201 to move, thereby making the movable part 22 move synchronously as a whole.

[0025] Meanwhile, a first support 2200 is provided on the lower side of the movable part 22. The first support 2200 is configured to support the base plate 2202. When the actuating element 23 moves, the base plate 2202 moves on the first support 2200. It can be understood that a guide device can also be provided between the base plate 2202 and the first support 2200 to limit the movement of the base plate 2202 and the frame 2201 in a limited direction. The limited direction is the movement towards the cutting assembly 10 or away from the cutting assembly 10. The guide device can be a sliding block device, a guide rod guide hole device, etc.

[0026] Furthermore, a limiting device is provided between the first support 2200 and the frame 2201 to limit the position of the first frame 2201, preventing excessive movement of the actuating element 23 from damaging the conveyor belt 204 or causing unintended damage to the slitting assembly 10. In this embodiment, the limiting device includes a limiting plate 2204, which includes a fixing part 21 fixed to the front side plate 2203 and an extension part extending towards the first support 2200. In this embodiment, the first support 2200 is provided with... Below the frame 2201, the protrusion extends downward and is exposed. The first bracket 2200 includes a limiting rod 2205 extending towards the limiting plate 2204. At the same time, the protrusion includes a limiting hole 2207 corresponding to the limiting rod 2205. When the first frame 2201 moves, the limiting hole 2207 can be movably fitted onto the limiting rod 2205. Meanwhile, a limiting block is provided on the limiting rod 2205 to limit the maximum movement position of the limiting plate 2204.

[0027] Furthermore, the position of the limiting block on the limiting rod 2205 is adjustable, thereby adjusting the maximum movement position of the limiting plate 2204 and the first frame 2201 when moving towards the cutting assembly 10. In this embodiment, the limiting rod 2205 is a screw, and the limiting block is a first limiting nut 2206, so that the position can be adjusted by adjusting the position of the first limiting nut 2206 on the screw.

[0028] Furthermore, the actuating element 23 includes a movable end 231, and the limiting plate 2204 is fixedly connected to the movable end 231 of the actuating element 23.

[0029] Furthermore, the first conveying device 20 also includes a middle idler roller 205 disposed between the first idler roller 201 and the second idler roller 202, and the middle idler roller 205 divides the supporting surface 2040 into a front section 2041 and a rear section 2042, wherein the front section 2041 is the area of ​​the supporting surface 2040 between the first idler roller 201 and the middle idler roller 205, and the rear section 2042 is the area of ​​the supporting surface 2040 between the middle idler roller 205 and the second idler roller 202, and the middle idler roller 205 is configured to be height adjustable.

[0030] Specifically, the fixing part 21 includes a second frame 2101. An adjustment device is provided between the middle idler roller 205 and the second frame 2101 to adjust the height of the middle idler roller 205. The adjustment device includes a support bracket 2053 fixed on the second frame 2101. The support bracket 2053 includes a through hole, and a support rod 2051 passes through the through hole and includes an upper section located on the upper side of the support bracket 2053 and a lower section located on the lower side of the support bracket 2053. At the same time, the upper section of the support rod 2051 includes a connecting end. The middle idler roller 205 is rotatably disposed at the connecting end. A spring 2052 is provided between the connecting end and the support bracket 2053. The spring 2052 is configured to have an elastic force that causes the connecting end to move upward. At the same time, a limit block is provided in the lower section to limit the maximum position of the upward movement of the connecting end. In this embodiment, the lower section is provided with external threads, and the limit block is a second limit nut 2054.

[0031] Understandably, when the actuating element 23 drives the moving part 22 to move towards or away from the slitting assembly 10, the conveyor belt 204 is tightened or relaxed. The height of the middle idler roller 205 is adaptively adjusted by the adjusting device to keep the conveyor belt 204 taut. In addition, it can be seen that since the height of the middle idler roller 205 is adjustable, the angle between the front section 2041 and the rear section 2042 changes, thereby changing the angle at which the material to be slit enters the gap 13. That is, by adjusting the position of the moving part 22, the angle between the front section 2041 and the horizontal direction is adjusted, thereby adjusting the angle at which the material to be slit enters the gap 13, making it easier for the material to be slit to enter the gap 13 for slitting.

[0032] In this embodiment, the actuating element 23 is a cylinder configured to drive the moving part 22 to move. In other embodiments, the actuating element 23 may also be an electric cylinder, a hydraulic cylinder, or a linear motor, etc., which will not be described in detail here. Meanwhile, the first conveying device 20 also includes a drive roller 203 for driving the conveyor belt 204 to move.

[0033] Furthermore, the fixed part 21 also includes a first adsorption box 211, and the movable part 22 includes a second adsorption box 221. The first adsorption box 211 and the second adsorption box 221 create a negative pressure on the support surface 2040 and the area adjacent to the support surface 2040, thereby keeping the material to be cut in an attached state during the conveying process.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
