Description

Technical Field

[0001] The utility model relates to the technical field of wet wipe production, in particular to a trimming device for preparing degreasing wet wipes. Background Art

[0002] Degreasing wipes are a type of cleaning product designed specifically for removing grease. They use a special cleaning formula that can quickly decompose and remove various stubborn grease stains, such as kitchen grease and car surface grease. They combine the convenience of wet wipes with the functionality of degreasing. During the preparation process, a trimming device is required to cut the wet wipe base material.

[0003] The Chinese utility model patent with publication number CN211053752U discloses a wet wipes trimming device for wet wipes production. When in use, the fixed plate is installed on a plane, and the wet wipes body is placed on the top of the first roller and the second roller. After the wet wipes body is driven by external force, the burrs on both sides of the wet wipes body contact the cutter head at the front end of the blade, and the burrs are cut off. At the same time, the burrs move along the outer wall of the curved plate and then fall into the box body. At the same time, after the burrs on the side of the wet wipes body close to the fixed plate are cut off, part of the burrs fall directly on the slide and then enter the box body, and part of the burrs stick to the flat plate. At the same time, the vibration motor drives the flat plate to vibrate, and the remaining burrs on the flat plate fall on the slide and finally fall into the box body, which is conducive to the burrs on the blade to quickly separate from the blade, solving the problem that the burrs will stick to the blade, which is not conducive to the blade continuously cutting the burrs.

[0004] However, when the device is actually cutting and forming the wet wipe substrate, the blade is passed through the wet wipe substrate. As the wet wipe substrate is only subjected to the pulling force of the front end, the pulling force on the edge is not uniform, which can easily cause burrs and tears after cutting, reducing the production quality of the finished wet wipe product.

[0016] In a preferred embodiment of the present invention, limiting rings are fixed to the side surfaces of the conveying roller close to both ends, and one side of the limiting ring is in contact with one side of the substrate.

[0017] In a preferred embodiment of the present invention, a plurality of supporting legs are fixed to the bottom of the device body, and anti-slip pads are provided at the bottom of the supporting legs.

[0018] The present invention solves the defects in the background technology and has the following beneficial effects:

[0019] (1) The utility model provides a trimming device for preparing degreasing wet wipes. By arranging a cutting component on the top of the substrate, the trimming device can form a production line for degreasing wet wipes. The substrate is passed through the inner side of the equipment body and interlacedly wound on a number of conveyor rollers. The external production line provides a pulling force to drive the substrate to the cutting area. With the cooperation of the clamping component, the edge of the substrate can be clamped. With the cooperation of the first cylinder, the lifting plate, a number of cutting knives and the power source, the substrate can be lifted to a suitable tight state, so that it can guide the substrate to form the expected edge contour. Then, the trimming operation in the tight state can fit the shape of the lifting plate more accurately, improve the cutting accuracy, and at the same time, the tension on the edge of the tight substrate is more uniform, which helps to reduce the burrs and tearing after cutting, thereby improving the production quality of the finished wet wipes.

[0020] (2) In the present invention, a pressing assembly is provided on the top of the substrate. When the substrate moves to the cutting area and stops moving, the substrate can be pressed on the top of the T-shaped bracket by the pressing block through the cooperation of the lifting member, the moving rod, the L-shaped connecting rod, the pressing block and the T-shaped bracket, and a multi-point pressing effect can be formed on both sides of the substrate, which helps to improve the stability in the subsequent trimming and cutting. With the cooperation of the rubber pad at the bottom of the pressing block, the friction with the substrate surface during the pressing process can be increased, and the phenomenon of damage to the substrate caused by hard contact during the pressing process can be avoided.

[0021] (3) In the present invention, by fixing limiting rings on the sides of the conveying rollers near both ends, when the substrate is staggered and wound around several conveying rollers, the limiting rings on each conveying roller cooperate with each other. Since one side of the limiting ring contacts one side of the substrate, the substrate can be limited on the conveying roller, thereby enabling the substrate to pass through the cutting area more smoothly, reducing the downtime caused by the deviation of the substrate, and thus improving the continuity and stability of the production line.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0030] It should be noted that the trimming device for preparing degreasing wet wipes is preferably suitable for preparing and trimming degreasing wet wipes using a degreasing wet wipe liquid whose main components include one or more of water, emulsifier, surfactant, alcohol or isopropyl alcohol.

[0031] like Figure 1 and Figure 2 As shown, a trimming device for preparing degreasing wet wipes includes: an equipment body 1, a plurality of conveying rollers 11 rotatably connected to the inner side of the equipment body 1, and a substrate 2 interlaced and wound between the plurality of conveying rollers 11; a cutting assembly and a pressing assembly for pressing the edge of the substrate 2 are provided on the top of the substrate 2; the cutting assembly includes: a plurality of cutting knives 3 provided on the top of the substrate 2, a lifting plate 31 provided on the bottom of the substrate 2, and a first cylinder 32 installed on the bottom inside the equipment body 1; the output end of the first cylinder 32 is fixed to the bottom of the lifting plate 31; a power source for driving the plurality of cutting knives 3 to rise and fall is provided on the top of the equipment body 1, and the side surfaces of the plurality of cutting knives 3 form a rectangle.

[0032] It should be noted that the lifting plate 31 and the rectangle are both located in the middle of the equipment body 1, and the length and width of the side of the lifting plate 31 are the same as the length and width of the inner side of the rectangle; the trimming device can constitute a production line for degreasing wet wipes. After the substrate 2 passes through the inner side of the equipment body 1 and is interlaced and wound on several conveyor rollers 11, the external production line provides a pulling force, which can drive the substrate 2 to move inside the equipment body 1 to the cutting area. After stopping, with the cooperation of the clamping component, the edge of the substrate 2 can be clamped, and the first cylinder 32 is started to push the lifting plate 31 upward, driving the lifting plate 31 to contact the bottom of the substrate 2, and lifting the substrate 2 to a suitable tight state, so that it guides the substrate 2 to form the expected edge contour, which helps In order to reduce the deformation and movement of the subsequent substrate 2 during the cutting process, the cutting knives 3 are driven downward by the cooperation of the power source. Since the side surfaces of the cutting knives 3 form a rectangle, and the length and width of the side surfaces of the lifting plate 31 are the same as the length and width of the inner side of the rectangle, the cutting knives 3 can be made downward along the raised outer edge of the lifting plate 31 to cut the substrate 2. After driving the cutting knives 3 upward to complete the trimming, the staff can take out the cut wet wipes, and then the trimming operation in a taut state can more accurately fit the shape of the lifting plate 31, thereby improving the cutting accuracy. At the same time, the tension on the edge of the taut substrate 2 is more uniform, which helps to reduce burrs and tearing after cutting, thereby improving the production quality of the finished wet wipes.

[0033] In some embodiments, a limiting ring 7 is fixed to the side surfaces of the conveying roller 11 near both ends, and one side of the limiting ring 7 contacts one side of the substrate 2 .

[0034] It should be noted that there are two limiting rings 7 on each conveyor roller 11, and they are symmetrically distributed, and the distance between the two limiting rings 7 is the same as the width of the substrate 2; when the substrate 2 is staggered and wound on several conveyor rollers 11, the limiting ring 7 set on each conveyor roller 11, because one side of the limiting ring 7 contacts one side of the substrate 2, can limit the substrate 2 on the conveyor roller 11, thereby enabling the substrate 2 to pass through the cutting area more smoothly, reducing the downtime caused by the deviation of the substrate 2, thereby improving the continuity and stability of the production line.

[0035] In some embodiments, several support legs 8 are fixed to the bottom of the device body 1, and anti-slip pads are provided at the bottom of the support legs 8; through the setting of the support legs 8, the device body 1 can be supported, and through the setting of the anti-slip pads, an anti-slip and stable effect can be achieved during support.

[0036] like Figure 3As shown, in some embodiments, the clamping assembly includes: a plurality of movable rods 4 arranged on the inner side of the equipment body 1, a plurality of L-shaped connecting rods 41 fixed on the top of the movable rods 4, and a pressing block 42 fixed on the bottom of the plurality of L-shaped connecting rods 41; a plurality of T-shaped brackets 43 are fixed to the inner bottom of the equipment body 1, and a plurality of lifting parts for driving the plurality of movable rods 4 to rise and fall are provided on the inner side of the equipment body 1.

[0037] It should be noted that a number of T-shaped brackets 43 are symmetrically arranged on both sides of the lifting plate 31, the top of the T-shaped bracket 43 overlaps the bottom of the substrate 2, and a number of pressing blocks 42 are located on top of the substrate 2 and the T-shaped brackets 43; the number of moving rods 4 is preferably two, symmetrically distributed on both sides of the substrate 2, and the number of L-shaped connecting rods 41 and pressing blocks 42 on each moving rod 4 is preferably two, symmetrically distributed on the top of the moving rod 4 near both ends; when the substrate 2 moves to the cutting area and stops moving, the substrate 2 can be brought to the cutting area by the cooperation of a number of lifting parts. The two moving rods 4 are driven to move downward, and the L-shaped connecting rod 41 and the pressing block 42 on the moving rod 4 are driven to move downward synchronously. Since the pressing block 42 is located on the top of the substrate 2 and several T-shaped brackets 43, when the pressing block 42 moves downward and contacts the top of the substrate 2, the downward pressure applied to the top of the substrate 2 is transmitted to the top of the T-shaped bracket 43, and then the substrate 2 can be pressed against the top of the T-shaped bracket 43 by the pressing block 42, which can form a multi-point pressing effect on both sides of the substrate 2, which helps to improve the stability in subsequent trimming and cutting.

[0038] In some embodiments, a rubber pad is fixed to the bottom of the pressing block 42 for increasing friction and preventing hard contact. Through the provision of the rubber pad, when the pressing block 42 moves down to the top of the substrate 2, the friction with the surface of the substrate 2 during the pressing process can be increased, and damage to the substrate 2 caused by hard contact during pressing can be avoided.

[0039] like Figure 3 and Figure 4 As shown, in some embodiments, the lifting member includes: a lifting slot 5 opened on the inner side of the device body 1, a threaded rod 51 arranged on the inner side of the lifting slot 5, and a servo motor 52 fixed on the top of the device body 1; the output end of the servo motor 52 is fixed to the top of the threaded rod 51, and the side of the threaded rod 51 is threadedly connected with a convex block 53, and the convex block 53 is located on one side outside the lifting slot 5 and is fixed to one side of the moving rod 4.

[0040] It should be noted that the side surfaces of the threaded rod 51 near both ends are rotatably connected to the inner side of the lifting groove 5, and the cross-sectional shape and size of the convex block 53 inside the lifting groove 5 are the same as the cross-sectional shape and size of the inner side of the lifting groove 5; the servo motor 52 is started to drive the threaded rod 51 in the lifting groove 5 to rotate. Since the convex block 53 is threadedly connected to the side surface of the threaded rod 51, and its cross-sectional shape and size are the same as the cross-sectional shape and size of the inner side of the lifting groove 5, the convex block 53 can be driven to move downward along the side surface of the threaded rod 51, and at the same time, the moving rod 4 on one side of the convex block 53 can be driven to move downward synchronously, thereby driving the moving rod 4 to rise and fall.

[0041] like Figure 5 As shown, in some embodiments, the power source includes: a four-legged bracket 6 fixed to the top of the equipment body 1, a second cylinder 61 fixed to the top of the four-legged bracket 6, and a pressure plate 62 fixed to the output end of the second cylinder 61 at the bottom of the four-legged bracket 6; the bottom of the pressure plate 62 is fixed to the top of several cutting knives 3.

[0042] It should be noted that the four-legged bracket 6 can be removably connected to the top of the equipment body 1 to facilitate maintenance of the equipment; starting the second cylinder 61 pushes the pressure plate 62 located at the output end at the bottom of the four-legged bracket 6 to move downward, which can drive the multiple cutting knives 3 fixed at the bottom of the pressure plate 62 to move synchronously, and thus can provide power for the multiple cutting knives 3 to move up and down.

[0043] When the present invention is in use, the substrate 2 passes through the inner side of the equipment body 1 and is interlaced and wound around several conveying rollers 11. The external production line provides a pulling force, which can drive the substrate 2 to move inside the equipment body 1 to the cutting area. After stopping, the servo motor 52 is started to drive the threaded rod 51 in the lifting groove 5 to rotate. Since the convex block 53 is threadedly connected to the side of the threaded rod 51, and the cross-sectional shape and size are the same as the cross-sectional shape and size of the inner side of the lifting groove 5, the convex block 53 can be driven to move downward along the side of the threaded rod 51, and at the same time, the moving rod 4 on one side of the convex block 53 is driven to move downward synchronously, which can drive the L-shaped connecting rod 41 and the pressing block 42 on the moving rod 4 to move downward synchronously. Since the pressing block 42 is located at the top of the substrate 2 and several T-shaped brackets 43, when the pressing block 42 moves downward and contacts the top of the substrate 2, the downward pressure applied to the top of the substrate 2 is transmitted to the top of the T-shaped bracket 43, so that the substrate 2 can be pressed tightly against the top of the T-shaped bracket 43 by the pressing block 42, which can move the substrate 2 to the top of the T-shaped bracket 43. The two sides form a multi-point compression effect, and the first cylinder 32 is started to push the lifting plate 31 upward, driving the lifting plate 31 to contact the bottom of the substrate 2 and lift the substrate 2 to a suitable tight state, so that it guides the substrate 2 to form the expected edge contour, and the second cylinder 61 is started to push the pressing plate 62 at the output end of the bottom of the four-legged bracket 6 to move downward, which can drive the several cutting knives 3 fixed at the bottom of the pressing plate 62 to move synchronously. Since the side surfaces of the several cutting knives 3 form a rectangle, and the length and width of the side surfaces of the lifting plate 31 are the same as the length and width of the inner side of the rectangle, the cutting knives 3 can be made to cut the substrate 2 downward along the outer edge raised by the lifting plate 31. After driving the several cutting knives 3 to move upward to complete the trimming, the staff can take out the cut wet wipes, and then the trimming operation under the tension can more accurately fit the shape of the lifting plate 31, improve the cutting accuracy, and at the same time, the tension on the edge of the tight substrate 2 is more uniform, which helps to reduce the burrs and tearing after cutting, thereby improving the production quality of the finished wet wipes.
