Description

Technical Field

[0001] This application relates to the field of cutting devices, and more particularly to an automatic cutting device for the production of wiping paper. Background Technology

[0002] Wiping paper is generally made of long-fiber wood pulp or non-woven fabric and has a wide range of applications in both daily life and industrial production, such as wiping oil mist off mechanical equipment.

[0003] In related technologies, during the production process of wiping paper, the finished wiping paper is first wound onto a paper tube to form a paper roll. Then, as needed, the paper roll is divided or cut into short paper rolls of the required length along the radial direction. This division process is generally carried out by a division device or a cutting device. For a specific example of such a division device, please refer to the patent document with publication number CN222003632U, which discloses a paper roll cutting mechanism.

[0004] The cutting mechanism described above still has drawbacks in actual use. Specifically, after the paper roll is cut, the cut paper roll remains on the mounting shaft, and it needs to be manually removed from the mounting shaft later. Therefore, it still needs to be improved. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide an automatic cutting device for wiping paper production.

[0006] To achieve the above objectives, this application provides the following technical solution.

[0007] An automatic cutting device for producing wipes, used to cut rolls of wipes into sections, includes:

[0008] A support shaft, the support shaft being used to penetrate into the paper roll along a first direction to provide support for the paper roll;

[0009] The push-pull mechanism includes a base capable of linear movement along a first direction; the support shaft is rotatably connected to the base, and in the first direction, the support shaft and the base are positioned relative to each other; the end of the support shaft away from the base is freely suspended to form a discharge end;

[0010] A clamp is used to clamp and fix a paper roll that is sleeved on a support shaft to the support shaft; the clamp includes a stop surface for abutting one end of the paper roll near the base.

[0011] A first driving mechanism is used to drive the clamp to rotate around a first axis, the first axis being coincident with the axis of the support shaft;

[0012] A cutting mechanism for cutting the paper roll radially.

[0013] Compared with existing technologies, the advantages of this solution are:

[0014] In this design, the support shaft is mainly used to support the paper roll for subsequent cutting. A push-pull mechanism is also provided to push and pull the support shaft along the first direction. When the paper roll needs to be cut, the support shaft can be pushed forward into the cutting station, and the clamp can be driven to rotate by the first drive mechanism. Then the support shaft and the paper roll on the support shaft can rotate together. In conjunction with the radial cutting of the cutting mechanism, the paper roll can be radially cut and divided.

[0015] After the paper roll is cut, the clamp is released, and the support shaft is driven to move backward through the push-pull mechanism. Since the end of the paper roll is abutted against the stop surface, the paper roll is blocked by the stop surface during the backward movement of the support shaft, so that the support shaft is gradually pulled out of the paper roll, and the paper roll can fall down automatically to achieve unloading.

[0016] As an optional implementation of this application, the first driving mechanism includes:

[0017] A support frame that maintains its position;

[0018] A wheel, which is rotatably connected to a support frame about a first axis; a clamp is fixed on the wheel; both the wheel and the clamp have through holes at their centers for the support shaft to pass through in a first direction;

A disc is disposed between the guide wheels, and the edge of the disc is rotatably embedded in the groove of the guide wheel. Under the constraint of all the guide wheels, the disc can only rotate along a first axis.

[0020] Drive assembly, used to drive the wheel to rotate.

[0021] As an optional implementation of this application, the driving component includes:

[0022] The transmission ring is circular and coaxially fixed on the wheel disc;

[0023] An electric motor is used to drive the transmission ring to rotate, wherein the electric motor and the transmission ring are driven by gears or belts.

[0024] As an optional embodiment of this application, the push-pull mechanism further includes a first linear module, the first linear module including a slide rail extending along a first direction and a slide block slidably connected to the slide rail; the base is fixed on the slide block.

[0025] As an optional embodiment of this application, the support shaft passes through the base; at least one side of the base is provided with a limiting member, the limiting member is fixed on the support shaft, and the limiting member at least partially abuts against the side of the base and is movable relative to the side of the base.

[0026] As an optional embodiment of this application, the limiting member includes a roller that is capable of rolling on the side of the base.

[0027] As an optional embodiment of this application, the clamp is a chuck, which includes at least three jaws arranged in a circumferential array along the chuck, and each jaw can move synchronously along the radial direction of the chuck to clamp the paper roll.

[0028] As an optional embodiment of this application, the cutting mechanism includes:

[0029] A cutting machine that can feed the paper roll radially;

[0030] The second linear module is used to drive the cutter to feed radially along the paper roll.

[0031] As an optional embodiment of this application, the cutting mechanism further includes a third linear module, which is used to drive the second linear module and the entire cutting machine to move along a first direction.

[0051] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] See Figure 1-7As shown, this embodiment provides an automatic cutting device for producing wiping paper, used to cut paper rolls formed from wiping paper. Here, "paper roll" mainly refers to the wiping paper that, after processing, is usually wound onto a roll to form a paper roll. At this point, the width of the wiping paper (i.e., the axial length of the paper roll) is relatively long, and it needs to be cut radially to form two or more shorter paper rolls. The device provided in this embodiment is used for cutting and dividing paper rolls. The paper roll is as follows... Figure 1 As shown in section M.

[0053] This device mainly includes a frame 1, a push-pull mechanism 3, a clamp 4, a first drive mechanism 5, and a cutting mechanism 6, etc. The following is a detailed explanation of each component.

[0054] like Figure 1 As shown, the support shaft 2 is used to insert into the paper roll along a first direction to provide support for the paper roll. That is, the support shaft 2 is in the shape of a circular shaft and extends along the first direction, which mainly refers to a horizontal straight line. The diameter of the support shaft 2 is basically the same as, or slightly smaller than, the inner diameter of the paper roll. For example, the inner diameter of the paper roll is 0-5 mm larger than the support shaft 2, so that the support shaft 2 can be inserted into the paper roll relatively compactly to provide support for the paper roll.

[0055] Combination Figure 2 and Figure 3 As shown, the push-pull mechanism 3 includes a base 31 capable of linear motion along a first direction. In some embodiments, to drive the base 31 to move, the push-pull mechanism 3 further includes a first linear module 32, wherein the first linear module 32 can be an existing lead screw linear module. The lead screw linear module mainly consists of a slide rail 321, a slide block 322, a lead screw, and a motor. During operation, the motor drives the lead screw to rotate, thereby causing the slide block 322 to slide along the slide rail 321. Such lead screw linear modules are extensively described in the prior art and will not be elaborated upon here.

[0056] When the lead screw linear module is specifically applied as the first linear module 32 in this embodiment, the slide rail 321 extends along the first direction and is fixed on the frame 1, and the slide block 322 is slidably connected to the slide rail 321; the base 31 is fixed on the slide block 322; the slide rail 321 is fixed on the frame 1; the base 31 is moved by the movement of the slide block 322.

[0057] The support shaft 2 is rotatably connected to the base 31 via bearings, and in the first direction, the support shaft 2 and the base 31 are relatively positioned. This relative positioning can also be understood as the support shaft 2 being unable to move axially relative to the base 31; and the end of the support shaft 2 away from the base 31 is freely suspended, forming the unloading end. In short, the support shaft 2 can rotate on the base 31 and can move synchronously with the base 31 along the first direction.

[0058] The clamp 4 is used to clamp and fix the paper roll that is sleeved on the support shaft 2 onto the support shaft 2; the clamp 4 includes a stop surface 41 for blocking the paper roll near one end of the base 31.

[0059] In some embodiments, such as Figure 5 As shown, the clamp 4 can adopt a chuck structure, the chuck including at least three jaws arranged in a circumferential array along the chuck, and each jaw can move synchronously along the radial direction of the chuck to clamp the paper roll. For example, in this embodiment, the clamp 4 adopts an existing three-jaw chuck, including three jaws; the center of the chuck has a through hole for the support shaft 2 to pass through.

[0060] When clamp 4 secures the paper roll, the paper roll to be cut is first threaded onto the support shaft 2 until it reaches the chuck position. Then, the chuck's jaws are driven to move radially inward, causing each jaw to press against the paper roll. At this point, the paper roll is effectively pressed against the support shaft 2 by the jaws. Thus, clamp 4, support shaft 2, and paper roll form a single unit, and all three can rotate synchronously around the axis of support shaft 2. In other words, rotation of support shaft 2 will cause the paper roll to rotate synchronously. For ease of explanation, in this embodiment, the axis of support shaft 2 is referred to as the first axis L.

[0061] like Figure 5 As shown, the front end face of the chuck forms a blocking surface 41 to block the paper roll, that is, the diameter of the through hole in the center of the chuck is smaller than the diameter of the paper roll, so as to ensure that the paper roll will not pass through the through hole and will be blocked by the chuck.

[0062] like Figure 4 As shown, the first drive mechanism 5 is used to drive the clamp 4 to rotate around the first axis L. The cutting mechanism 6 is used to cut the paper roll radially.

[0063] Thus, when cutting is required, the support shaft 2 is first pushed to the cutting station via the base 31, and then the paper roll is threaded onto the support shaft 2 and fixed by the clamp 4; then the clamp 4 is driven to rotate, and the cutting mechanism 6 is activated to cut the paper roll radially. Since the paper roll rotates together with the support shaft 2, the cutting mechanism 6 can cut around the circumference of the paper roll to cut the paper roll.

[0064] After cutting is completed, the first drive mechanism 5 stops operating, and the clamp 4 releases its grip on the paper roll. Subsequently, the base 31 pulls the support shaft 2 backward in the first direction, so that the paper roll on the support shaft 2 can move backward together with the support shaft 2. When the paper roll moves to the chuck position, it will be blocked by the chuck's stop surface 41, thus preventing it from moving further backward. Meanwhile, the support shaft 2 continues to move backward, so the support shaft 2 is continuously pulled out of the paper roll, eventually causing the paper roll on the support shaft 2 to fall off, achieving unloading.

[0065] To prevent the paper roll from falling directly to the ground, in some embodiments, such as Figure 1 As shown, the device also includes a top-opening receiving groove 11, which is located below the support shaft 2 and is used to receive paper rolls that fall from the support shaft 2.

[0066] In some embodiments, such as Figure 4 As shown, the specific structure of the first drive mechanism 5 is as follows: the first drive mechanism 5 includes a support frame 51, a wheel 52, a guide wheel 521 and a drive assembly 53.

[0067] The support frame 51 is fixed on the frame 1 and remains in a fixed position.

[0068] The wheel 52 serves as the mounting carrier for the clamp 4, fixing the clamp 4 to the wheel 52. The wheel 52 is rotatably connected to the support frame 51 around the first axis L. Since the support shaft 2 needs to pass through the wheel 52, in this embodiment, a through hole for the support shaft 2 to pass through is also provided at the center of the wheel 52.

[0069] Since the roulette wheel 52 needs to rotate, and the support shaft 2 passes through its center, it is not possible to directly connect a shaft to the roulette wheel to achieve rotation. Therefore, as follows... Figure 4 As shown, in this embodiment, at least three guide wheels 521 are provided. Taking three guide wheels 521 as an example, the three guide wheels 521 are arranged in a circular array on the support frame 51 with the first axis L as the center; and each guide wheel 521 has a wheel groove, for example, the guide wheel 521 is an I-beam wheel. Moreover, the guide wheels 521 are all rotatably connected to the support frame 51, and the rotation axis of the guide wheel 521 is parallel to the first direction.

[0070] The wheel 52 is disposed between each guide wheel 521, and the edge of the wheel 52 is rotatably embedded in the groove of the guide wheel 521. Under the constraint of all the guide wheels 521, the wheel 52 can only rotate along the first axis L. At this time, all the guide wheels 521 work together to guide the rotation of the wheel 52, so that the wheel 52 rotates along the first axis L and cannot move axially.

[0071] The drive assembly 53 is used to drive the wheel 52 to rotate. For example, the drive assembly 53 consists of a transmission ring 531 and a motor 532, which are circular and coaxially fixed on the wheel 52. The motor 532 is used to drive the transmission ring 531 to rotate. The motor 532 and the transmission ring 531 are connected by gear transmission. For example, the outer peripheral wall of the transmission ring 531 has teeth, so that the transmission ring 531 forms a gear structure. A drive gear 533 is fixed on the main shaft of the motor 532. The drive gear 533 meshes with the teeth of the transmission ring 531. The motor 532 is fixed on the frame 1. In this way, the motor 532 drives the drive gear 533 to rotate, thereby driving the transmission ring 531 to rotate, and thus driving the wheel 52 and the clamp 4 to rotate.

[0072] Of course, in other embodiments, the motor 532 and the transmission ring 531 can also be connected by a belt drive, etc., which are not specifically limited here.

[0073] Because the push-pull mechanism 3 pushes and pulls the support shaft 2, especially during the unloading process, the support shaft 2 needs to overcome the friction between the support shaft 2 and the paper roll to be pulled out of the paper roll. Therefore, the support shaft 2 will generate an axial pulling force relative to the base 31. With long-term use, this can easily cause the support shaft 2 to shift axially relative to the base 31, thus loosening. Based on this, in some embodiments:

[0074] like Figure 7 As shown, the support shaft 2 passes through the base 31; at least one side of the base 31 is provided with a limiting member 21. For example, in this embodiment, the base 31 is provided with limiting members 21 on both sides, with two limiting members 21 on each side. Since the structures of each limiting member 21 are basically the same, this embodiment will only use one of them as an example for specific explanation.

[0075] The limiting member 21 is fixed on the support shaft 2, and the limiting member 21 at least partially abuts against the side of the base 31 and can move relative to the side of the base 31. At this time, the limiting member 21 can limit the support shaft 2, restricting the axial displacement of the support shaft 2 relative to the base 31.

[0076] In order to reduce the friction between the limiting member 21 and the base 31, in some embodiments, the limiting member 21 is provided with a roller 211, which can roll on the side of the base 31.

[0077] As an optional implementation method, such as Figure 1 As shown, the cutting mechanism 6 includes a cutting machine 61, a second linear module 62, and a third linear module 63.

[0078] The cutting machine 61 can feed radially along the paper roll. For example, in this embodiment, the cutting machine 61 can be a circular saw, using a circular saw blade as the cutting device.

[0079] The second linear module 62 is used to drive the cutter 61 to feed radially along the paper roll. For example, the second linear module 62 can be a telescopic component, such as a cylinder, hydraulic cylinder, electric cylinder, or a lead screw linear module.

[0080] In this specific embodiment, the cutting machine 61 is located directly above the support shaft 2, and it performs radial cutting on the paper roll along the vertical direction.

[0081] The function of the third linear module 63 is to drive the cutter 61 to move along the first direction, thereby adjusting the cutting length of the paper roll, or adjusting the cutting position of the cutter 61 in the first direction.

[0082] Specifically, the third linear module 63 is used to drive the second linear module 62 and the cutting machine 61 to move together in the first direction. Preferably, the third linear module 63 is a lead screw linear module.

[0083] The third linear module 63 can be directly fixed to the roof of the factory building by hoisting, or an additional fixing frame can be set up to fix it.

[0084] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.
