Description

Technical Field

[0001] This utility model relates to the field of wet wipe processing technology, and in particular to a wet wipe correction device for a wet wipe slitting equipment. Background Technology

[0002] In today's fast-paced life, people's demands for hygiene and convenience are constantly increasing. As a convenient cleaning product, wet wipes are experiencing continuous market demand growth. Traditional wet wipe processing and slitting technologies suffer from low efficiency and poor precision, making it difficult to meet the ever-expanding market size. With the advancement of production processes, advanced slitting equipment and technologies have emerged. High-precision cutting tools and intelligent slitting control systems are gradually becoming more widespread, enabling precise control of slitting dimensions, improving production efficiency, and reducing material waste. In addition, to meet the diverse needs for wet wipe specifications and materials in different scenarios, new slitting technologies also need to have stronger adaptability to drive the wet wipe processing and slitting industry to new heights.

[0003] In existing technologies, wet wipes are prone to shifting during the slitting process, resulting in size deviations and affecting product processing quality. Existing slitting machines are often fixed, making it difficult to quickly and accurately adjust the spacing between the slitting blades, which limits the applicable range of the slitting machine and hinders its widespread use.

[0004] To address the aforementioned issues, an existing patent (publication number: CN213054928U) proposes a wet wipe correction device for a wet wipe slitting machine. This device involves fixing a first-order clamping component and a second-order clamping component to the middle of the left and right ends of the machine housing, respectively. A first-order sliding groove is opened in the middle of the lower and upper ends of the machine housing, and an anti-deviation device is slidably installed inside the first-order sliding groove. A marking device and a cutting device are fixedly installed on the lower left and lower right ends of the machine housing, respectively. This invention provides a corrective slitting device for wet wipe processing. By observing whether the markings on the slids of the finished wet wipes coincide with the cutting lines of the slitting blade, the anti-deviation device is driven to move left and right, thereby promptly correcting slitting errors and improving product processing quality. The sliding seat and the slitting blade slide along the second and third sliding grooves, respectively, and an infrared transmitter and receiver are used to achieve rapid and precise adjustment of the distance between the slitting blades, making this slitting machine widely applicable.

[0005] To address the aforementioned issues, existing patents offer solutions. However, when cutting long strips of wet wipes, the entire strip is transported on a conveyor belt. If the transport speed is uneven and a section becomes skewed, it will cause the entire strip of wet wipes to become skewed, resulting in the cutting blade tilting. Furthermore, during the cutting process, existing technologies use pressure blocks at the transport end to directly press down on the uncut side of the wet wipe, fixing it in place to prevent skew. However, this direct pressing may cause internal damage to the wet wipes or breakage of the outer packaging.

[0006] To address this, a wet wipe correction device for a wet wipe cutting equipment is proposed. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a wet wipe correction device for a wet wipe slitting equipment, comprising a conveyor belt, a slitting bracket movably connected to the outer side of the conveyor belt, a transfer correction mechanism movably connected to the outer side of the slitting bracket, the transfer correction mechanism being disposed at the top of the conveyor belt, and a slitting buffer positioning mechanism movably connected to the inner side of the bottom of the slitting bracket.

[0009] The transfer correction mechanism includes a positioning push plate, a connecting arm, a connecting rod, a pull rod, and a reciprocating drive assembly. The connecting rod is slidably connected to the top of the slitting bracket, the connecting arm is fixedly connected to the top of the connecting rod, the connecting arm is fixedly connected to the top of the positioning push plate, the positioning push plate is set on the top of the conveyor belt, the pull rod is rotatably connected to the outside of the connecting rod, the pull rod is movably connected to the outside of the reciprocating drive assembly, and the reciprocating drive assembly is movably connected to the top of the slitting bracket.

[0010] Preferably, the cutting buffer positioning mechanism includes a bearing plate, nested telescopic rods, a connecting block, a positioning pressure block, a first telescopic support, a compression spring, a second telescopic support, and a tension spring.

[0011] Preferably, the support plate is disposed at the bottom of the inner side of the cutting bracket, the nested telescopic rod is fixedly connected to the bottom of the support plate, and the positioning block is fixedly connected to the bottom of the nested telescopic rod.

[0012] Preferably, the first telescopic support is fixedly connected to the top and bottom of the inner side of the nested telescopic rod, the linkage block is fixedly connected to the bottom of the top first telescopic support, the linkage block is fixedly connected to the top of the bottom first telescopic support, the compression spring is movably connected to the outside of the first telescopic support, the second telescopic support is rotatably connected to the outside of the linkage block, the second telescopic support is rotatably connected to the inner side of the nested telescopic rod, and the tension spring is movably connected to the outside of the second telescopic support.

[0013] Preferably, the reciprocating drive assembly includes a support shaft, a rotating block, a connecting gear, a drive residual tooth, and a torsion spring.

[0014] Preferably, the supporting rotating shaft is movably connected to the top of the slitting bracket, the rotating block is fixedly connected to the top of the supporting rotating shaft, the connecting rod is rotatably connected to the outside of the connecting block, the connecting gear is fixedly connected to the outside of the supporting rotating shaft, the driving residual tooth is meshed with the outside of the connecting gear, the driving residual tooth is movably connected to the top of the slitting bracket, and the torsion spring is movably connected to the outside of the supporting rotating shaft.

[0015] Preferably, the outer side of the positioning push plate is movably connected with an elastic contact pad.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a transfer correction mechanism, can automatically correct the position of wet wipes conveyed on the conveyor belt, ensuring accurate transfer path. By driving the residual tooth motor to drive the linkage structure, the positioning push plate pushes the skewed wet wipes to the center position, solving the problem that the skew of the long strip packaged wet wipes caused by uneven transfer speed in a certain section, which in turn leads to the overall skew of the long strip wet wipes and the tilt of the cutting blade. When the residual tooth is without teeth, the torsion spring drives the linkage structure to reset. When the residual tooth is with teeth, it can push again, realizing reciprocating correction, ensuring that the wet wipes are always in the correct position on the conveyor belt, providing conditions for accurate cutting.

[0019] 2. This application solves the problems of easy displacement of wet wipes during cutting and damage caused by traditional pressure block fixing methods by setting a cutting buffer positioning mechanism. By setting a positioning pressure block supported by a nested telescopic rod at the bottom front side of the support plate, the wet wipes are pressed and positioned before the hot cutting blade contacts them, preventing cutting displacement. During the pressing process, the nested telescopic rods contract in a stepwise manner. The first telescopic support and the compression spring, and the second telescopic support and the tension spring respectively accumulate elastic potential energy and generate a reverse repulsive force to achieve buffering. In this way, the position of the wet wipes is fixed during cutting, and the internal damage of the wet wipes or the breakage of the outer packaging is avoided due to direct heavy pressure.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A wet wipe correction device for a wet wipe slitting equipment includes a conveyor belt 1, a slitting bracket 2 movably connected to the outer side of the conveyor belt 1, a transfer correction mechanism 3 movably connected to the outer side of the slitting bracket 2, the transfer correction mechanism 3 being disposed at the top of the conveyor belt 1, and a slitting buffer positioning mechanism 4 movably connected to the inner side of the bottom of the slitting bracket 2.

[0029] The transfer correction mechanism 3 includes a positioning push plate 31, a connecting arm 32, a connecting rod 33, a pull rod 34, and a reciprocating drive assembly 35. The connecting rod 33 is slidably connected to the top of the slitting bracket 2. The connecting arm 32 is fixedly connected to the top of the connecting rod 33 and the top of the positioning push plate 31. The positioning push plate 31 is set on the top of the conveyor belt 1. The pull rod 34 is rotatably connected to the outside of the connecting rod 33 and movably connected to the outside of the reciprocating drive assembly 35. The reciprocating drive assembly 35 is movably connected to the top of the slitting bracket 2.

[0030] In this embodiment: the reciprocating drive can drive the pull rod 34, the connecting rod 33, and the connecting arm 32 to transmit power, thereby driving the positioning push plate 31 located at the top of the conveyor belt 1 to reciprocate, which can push and position the material on the conveyor belt 1, so that it is located at the center position of the conveyor belt 1 for transfer. Specifically, as shown in the figure... Figure 1 , Figure 4 , Figure 5 As shown, the cutting buffer positioning mechanism 4 includes a bearing plate 41, a nested telescopic rod 42, a linkage block 43, a positioning pressure block 44, a first telescopic support column 45, a compression spring 46, a second telescopic support column 47, and a tension spring 48.

[0031] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the bearing plate 41 is located at the bottom of the inner side of the cutting bracket 2, the nested telescopic rod 42 is fixedly connected to the bottom of the bearing plate 41, and the positioning block 44 is fixedly connected to the bottom of the nested telescopic rod 42.

[0032] Specifically, such as Figure 1 , Figure 4 , Figure 5 As shown, the first telescopic support column 45 is fixedly connected to the top and bottom of the inner side of the nested telescopic rod 42, the linkage block 43 is fixedly connected to the bottom of the top first telescopic support column 45, the linkage block 43 is fixedly connected to the top of the bottom first telescopic support column 45, the compression spring 46 is movably connected to the outside of the first telescopic support column 45, the second telescopic support column 47 is rotatably connected to the outside of the linkage block 43, the second telescopic support column 47 is rotatably connected to the inner side of the nested telescopic rod 42, and the tension spring 48 is movably connected to the outside of the second telescopic support column 47.

[0033] In this embodiment: During the cutting process, the hydraulic cylinder 6 drives the hot cutting blade 7 downward. Before the hot cutting blade 7 contacts the wet wipe to be cut, the positioning block 44, supported by the nested telescopic rod 42 at the bottom front side of the support plate 41, contacts and presses the wet wipe to prevent cutting deviation. During pressing, the nested telescopic rod 42 contracts in a stepwise manner. The linkage block 43 is connected to the inner wall of the nested telescopic rod 42 through the first telescopic support column 45 at the top and bottom and the outer compression spring 46, and is compressed to accumulate elastic potential energy. At the same time, the second telescopic support column 47 and the outer tension spring 48 on the outer side of the linkage block 43 rotate downward and stretch, also accumulating elastic potential energy. When the elastic potential energy is sufficient, a reverse repulsive force is generated to buffer. Each section of the nested telescopic rod 42 repeats this process to achieve stepwise cutting buffering.

[0034] Specifically, such as Figure 2 , Figure 3 As shown, the reciprocating drive assembly 35 includes a support shaft 35a, a rotating block 35b, a connecting gear 35c, a drive residual tooth 35d, and a torsion spring 35e.

[0035] Specifically, such as Figure 2 , Figure 3 As shown, the support shaft 35a is movably connected to the top of the slitting bracket 2, the rotating block 35b is fixedly connected to the top of the support shaft 35a, the connecting rod 33 is rotatably connected to the outside of the connecting block 43, the connecting gear 35c is fixedly connected to the outside of the support shaft 35a, the driving residual tooth 35d is meshed with the outside of the connecting gear 35c, the driving residual tooth 35d is movably connected to the top of the slitting bracket 2, and the torsion spring 35e is movably connected to the outside of the support shaft 35a.

[0036] In this embodiment: by starting the motor at the bottom of the drive tooth 35d, the tooth 35d is driven to rotate. Its toothed surface drives the connecting gear 35c that meshes with it, which in turn drives the support shaft 35a and the top rotating block 35b to rotate synchronously. When the rotating block 35b rotates, it pulls the pull rods 34 connected to both sides by the outer shaft. The pull rods 34 pull the two sets of connecting rods 33 inward. The connecting rods 33 drive the positioning push plate 31 to move inward on the conveyor belt 1 through the connecting power arm 32, pushing the wet wipe to be tested to the center position and correcting the transfer path. When the drive tooth 35d rotates to the toothless surface, it disengages from the connecting gear 35c. The outer torsion spring 35e of the support shaft 35a, which has accumulated elastic potential energy due to the previous rotation, rebounds quickly, causing the linkage structure to return to the initial position. When the drive tooth 35d rotates back to the toothed surface, the above action is repeated to perform positioning and pushing, realizing reciprocating correction.

[0037] Specifically, such as Figure 3 As shown, an elastic contact pad 5 is movably connected to the outer side of the positioning push plate 31. Specifically, as... Figure 1 As shown, a hydraulic cylinder 6 is movably connected to the top of the inner side of the slitting bracket 2, and a hot cutting blade 7 is movably connected to the bottom of the hydraulic cylinder 6. A support plate 41 is fixedly connected to the outer side of the top of the hot cutting blade 7. In this embodiment, the elastic contact pad 5 can prevent damage to the wet wipes caused by reciprocating correction, and the hydraulic cylinder 6 can drive the hot cutting blade 7 to perform the slitting of long-strand packaged wet wipes.

[0038] Working principle: When cutting long strips of wet wipes, the wet wipes to be cut are conveyed to the bottom of the die-cutting bracket by the conveyor belt 1. The hydraulic cylinder 6 drives the hot cutting blade 7 to move downwards, cutting the wet wipes into multiple small bags. During the transfer process of the conveyor belt 1, the motor at the bottom of the drive tooth 35d is started, and the drive tooth 35d starts to rotate. Its toothed surface drives the connecting gear 35c that meshes with it, which in turn drives the support shaft 35a and the rotating block 35b on top to rotate together. When the rotating block 35b rotates, it pulls the pull rods 34 connected to both sides by the outer shaft. The pull rods 34 pull the two sets of connecting rods 33 inward. The connecting rods 33 drive the positioning push plate 31 to move inward on the conveyor belt 1 through the connecting power arm 32, pushing the wet wipe to be tested to the center position and correcting the transfer path. When the drive tooth 35d rotates to the toothless surface, it disengages from the connecting gear 35c. The torsion spring 3 on the outside of the support shaft 35a accumulates elastic potential energy during rotation. 5e quickly rebounds, returning the linkage structure to its initial position. The toothed surface of the driven residual tooth 35d rotates back, and positioning is pushed again to achieve reciprocating correction. During cutting, before the hydraulic cylinder 6 drives the hot cutting knife 7 to contact the wet wipes to be cut, the positioning block 44, supported by the nested telescopic rod 42, at the bottom front of the bearing plate 41 first contacts the surface of the wet wipe and presses it in place to prevent displacement during cutting. During the pressing process, the nested telescopic rod 42 contracts in a stepwise manner. The first telescopic support 45 and its outer compression spring 46, which are connected to the inner wall of the nested telescopic rod 42 at the top and bottom of the linkage block 43, are pressed and accumulate elastic potential energy. The second telescopic support 47 and its outer tension spring 48 on the outside of the linkage block 43 rotate downward and stretch, also accumulating elastic potential energy. When the elastic potential energy accumulates to a certain extent, it generates a reverse repulsive force, which plays a buffering role. Each section of the nested telescopic rod 42 repeats this operation to achieve stepwise cutting buffering, and finally completes the cutting of the long strip packaged wet wipes.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
