Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, specifically to a multi-segment cutting structure for tissue paper breakage. Background Technology

[0002] Paper towels are a common household item. To facilitate users cutting paper towels according to different usage amounts, the current connection method for paper towels is usually point-break connection. Existing point-break paper towels are generally produced and processed by point-break folding equipment. A rotating point-break cutter continuously cuts point-break lines into the paper towel raw material strip. Then, a folding mechanism folds the paper towel strip that has completed point-break cutting. When it is folded to a certain thickness, the cutter will cut it at the point-break line, and then the cut product is conveyed outward.

[0003] Existing spot-cutting cutters are typically mounted on the outer surface of rollers and extend along the roller's axis. As the roller rotates, the spot-cutting cutter engages with a protruding ridge on the outer surface of another roller to achieve spot-cutting of the tissue paper. To achieve continuous cutting, the spot-cutting cutter is usually a one-piece structure, consisting entirely of a single metal plate. The cutter is typically long and thin, requiring multiple bolts along its length to ensure rigidity and cutting accuracy. This means that when the cutter needs replacement due to damage, maintenance personnel must remove and install all bolts, extending downtime and reducing the efficiency of tissue paper production. Furthermore, one-piece cutters often have higher manufacturing costs and greater processing difficulty, and they occupy more storage space when stored as spares, hindering storage and transportation.

[0004] In addition, the serrated structure of the spot-cutting blade needs to withstand high compressive stress during cutting. It is prone to chipping or curling during high-speed production, causing some of the paper towels to fail. Since the spot-cutting blade is a one-piece structure, when the spot-cutting blade is partially worn, the entire spot-cutting blade needs to be replaced, which undoubtedly increases the maintenance cost of paper towel production equipment.

[0005] Therefore, a new type of cutter structure is needed that can reduce maintenance costs caused by cutter damage and shorten maintenance time while ensuring the existing breakpoint cutting effect. Utility Model Content

[0006] This invention provides a multi-segment cutting structure for paper towel breaks, which, while ensuring the existing break-point cutting effect, can reduce maintenance costs caused by cutter damage and shorten the maintenance time required.

[0007] To solve the above problems, the present invention provides a multi-segment cutting structure for paper towel breakage, which adopts the following technical solution:

[0008] A multi-segment cutting structure for paper towel breakage includes multiple sets of cutting assemblies evenly distributed circumferentially along the outer surface of a roller. Each set of cutting assemblies includes a fixing component, a cutting blade, and a fixing element. The fixing component includes multiple mounting grooves arranged axially along the outer surface of the roller. The mounting grooves are used to install the cutting blade and the fixing element. There are multiple cutting blades and fixing elements. The cutting blade is fixed to the mounting groove by the fixing element. The cutting blade has a serrated blade to achieve breakage cutting of the paper towel.

[0009] This utility model discloses a multi-segment cutter structure for paper towel cuts. By setting multiple axially arranged mounting slots and cutters on the roller body, the cutter structure can complete the overall cutting of the paper towel through the combined action of the individual cutters. The serrated blades on the cutters form the cut points on the paper towel, thus achieving the connection of these cut points. Compared to traditional one-piece cutters, each cutter in this structure can independently achieve cut points per unit length on the paper towel. The combined cutting lengths of the individual cutters complete the overall cut point cutting of the paper towel, achieving the same cut point cutting effect as the original one-piece cutter. Furthermore, the cutter structure reduces the volume of a single cutter, thereby lowering the manufacturing difficulty and operating cost. Simultaneously, the axially arranged mounting method reduces the helical cutting angle required for the cutter to complete the paper towel cutting, thus improving the cutting quality.

[0010] In addition, the multi-segment cutter structure allows each cutter to be independently installed in its own mounting slot on the roller via fixing components. When one cutter is damaged, the operator only needs to disassemble and replace the cutter in the damaged part, without having to disassemble all cutters. This reduces maintenance costs and significantly shortens the repair time for cutter damage, thereby improving the overall production efficiency of the tissue paper production equipment.

[0011] Furthermore, each of the mounting grooves is arranged at an angle relative to the axis of the roller body to achieve point contact between the cutter and the mating roller.

[0012] Its beneficial effects are as follows: by setting each mounting groove at an angle relative to the axis of the roller body, the cutter installed in the mounting groove is also at an angle relative to the axis of the roller body. Thus, during the rotation and cooperation of the roller body and other cooperating rollers, the cutter and the paper towel can always maintain point contact, which reduces the wear on the surface of the cutter when cutting the paper towel and extends the service life of the cutter.

[0013] Furthermore, the mounting groove includes a fastener mounting groove and a cutter mounting groove, which are arranged in a stepped manner. The cutter mounting groove in the same mounting groove is located below the corresponding fastener mounting groove in the radial direction of the roller body.

[0014] Furthermore, the fixing member is a pressure block, which includes a fixing part and a pressing part. The fixing part is used to fix and connect the fixing member mounting groove, and the pressing part is used to press the cutter.

[0015] Its advantages are as follows: by using a pressure block to press the cutter into the cutter mounting slot, the difficulty of cutter maintenance is reduced, and operators can adjust the installation position of the cutter according to the actual production situation on site. Compared with the traditional bolt fixing method, the pressure block pressing method is more flexible and reduces the difficulty of adjustment for operators.

[0016] Furthermore, the mounting groove of the fastener has multiple mounting holes for inserting bolts, and the pressure block is fixedly mounted on the mounting groove of the pressure block by bolts.

[0017] Furthermore, the number of pressure blocks installed in each of the aforementioned fixing member mounting slots is not less than three, and each pressure block is evenly distributed along the length direction of the fixing member mounting slot to ensure the stability of the cutter fixed in the pressure block mounting slot.

[0018] Its beneficial effects are as follows: by setting three pressure blocks on the mounting slot of the fixing component to fix the cutter, the middle and both sides of the cutter can be evenly stressed under the action of the pressure blocks, which avoids the cutter gradually shifting during long-term operation due to uneven stress, thus ensuring the cutting accuracy of the paper towel.

[0019] Furthermore, the cutter includes a blade and a pressure plate. The blade has a rectangular plate structure and includes a pressing end and a cutting end. The pressure plate is fixedly installed on the pressing end of the blade and is used to cooperate with the pressure block to press the blade, thereby improving the stability of the cutter in the cutter mounting groove.

[0020] Its beneficial effects are as follows: by setting a pressure plate on the surface of the blade, the pressure block can help to press the blade tightly, increase the friction between the cutter and the pressure block, and ensure the stability of the cutter in the cutter mounting slot.

[0021] Furthermore, each of the mounting grooves is inclined from left to right toward the axis of the roller body in the radial direction of the roller body, such that the left end of the right cutter in the adjacent mounting groove is higher than the right end of the left cutter, and the length of the cutter is greater than the length of the cutter mounting groove, so that the left end of the cutter covers the upper side of the right end of the adjacent cutter on its left.

[0022] Its beneficial effects are as follows: by setting the mounting grooves in the radial direction of the roller body from left to right towards the roller body axis, the left end of the cutter located on the right side in the adjacent mounting groove can cover the right end of the cutter located on the left side in the radial direction of the roller body, avoiding the gap between adjacent cutters in the axial direction of the roller body. The cutter can complete continuous discontinuous cutting in the width direction of the paper towel while rotating with the roller body, preventing missed cutting on the paper towel and ensuring the quality of the discontinuous cutting of the paper towel.

[0023] Furthermore, the serrated blades of the covered portions of two adjacent cutters overlap each other in the radial direction of the roller to avoid incorrect breakage of the paper towel at the junction of two adjacent cutters.

[0024] Furthermore, each of the pressing blocks has a fixing hole for mounting bolts. The fixing hole is a countersunk hole to avoid the bolts affecting the cutting of the paper towel.

[0025] The beneficial effects of the multi-segment cutting blade structure for tissue paper breakage provided by this utility model are:

[0026] 1. This utility model discloses a multi-segment cutter structure for paper towel cuts. By setting multiple axially arranged mounting grooves and cutters on the roller body, the cutter structure can complete the overall cutting of the paper towel through the cooperative action of each cutter. The serrated blades on the cutters form the cut points of the paper towel, thus achieving the connection of these cut points. Compared to traditional one-piece cutters, each cutter in this structure can independently achieve cut points per unit length on the paper towel. The combined unit cutting lengths of the individual cutters complete the overall cut point cutting of the paper towel, achieving the same cut point cutting effect as the original one-piece cutter. Furthermore, the cutter structure reduces the volume of a single cutter, thereby reducing the manufacturing difficulty and operating cost. Simultaneously, the axially arranged mounting method also reduces the helical cutting angle required for the cutter to complete the paper towel cutting, thus improving the cutting quality.

[0027] In addition, the multi-segment cutter structure allows each cutter to be independently installed in its own mounting slot on the roller via fixing components. When one cutter is damaged, the operator only needs to disassemble and replace the cutter in the damaged part, without having to disassemble all cutters. This reduces maintenance costs and significantly shortens the repair time for cutter damage, thereby improving the overall production efficiency of the tissue paper production equipment.

[0028] 2. By setting each mounting groove at an angle relative to the axis of the roller body, the cutter installed in the mounting groove is also at an angle relative to the axis of the roller body. As a result, during the rotation and cooperation of the roller body and other cooperating rollers, the cutter and the paper towel can always maintain point contact, which reduces the wear on the surface of the cutter when cutting the paper towel and extends the service life of the cutter.

[0029] 3. By using a clamping block to press the cutter into the cutter mounting slot, the difficulty of cutter maintenance is reduced, and operators can adjust the installation position of the cutter according to the actual production situation on site. Compared with the traditional bolt fixing method, the clamping block method is more flexible and reduces the difficulty of adjustment for operators.

[0030] 4. By setting three pressure blocks on the mounting slot of the fixing component to fix the cutter, the middle and both sides of the cutter can be evenly stressed under the action of the pressure blocks, which avoids the cutter gradually shifting during long-term operation due to uneven stress and ensures the cutting accuracy of the paper towel.

[0031] 5. By setting a stainless steel pressure plate on the surface of the blade, the pressure block can be used to press the blade tightly, increasing the friction between the cutter and the pressure block, thus ensuring the stability of the cutter when installed in the cutter mounting slot.

[0032] 6. By tilting the mounting grooves from left to right towards the roller axis in the radial direction of the roller body, the left end of the cutter on the right side of the adjacent mounting groove can cover the right end of the cutter on the left side in the radial direction of the roller body. This avoids gaps between adjacent cutters in the axial direction of the roller body. As the cutter rotates with the roller body, it can complete continuous discontinuous cutting in the width direction of the paper towel, preventing missed cuts on the paper towel and ensuring the quality of the discontinuous cutting of the paper towel.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0043] The main concept of this invention lies in setting multiple axially arranged mounting grooves 31 and cutters 4 on the roller body 1, enabling the cutter assembly 2 to complete the overall cutting of the paper towel through the cooperation of each cutter 4. The serrated blades 46 on the cutters 4 form the break points of the paper towel, thereby achieving the connection of the break points. Compared with the traditional one-piece cutter 4, each cutter 4 in the cutter structure 2 can independently achieve the break point cutting per unit length on the paper towel. The unit cutting length of each cutter 4 is combined to complete the overall break point cutting of the paper towel, thus achieving the break point cutting effect of the original one-piece cutter 4. In addition, the cutter structure 2 reduces the volume of a single cutter 4, thereby reducing the manufacturing difficulty and usage cost of the cutter 4. At the same time, the axially arranged mounting method can also reduce the spiral cutting angle of the cutter 4 when cutting the paper towel, thereby improving the cutting quality of the paper towel.

[0044] In addition, the multi-segment cutter structure 2 allows each cutter 4 to be independently installed in each mounting slot 31 of the roller body 1 via the fixing part 5. When one of the cutters 4 is damaged, the operator only needs to disassemble and replace the cutter 4 in the damaged part, without having to disassemble all the cutters 4. This reduces maintenance costs and greatly shortens the repair time for the damaged cutters 4, thereby improving the overall production efficiency of the tissue paper production equipment.

[0045] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0046] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0047] Embodiment 1 of a multi-segment cutting structure for tissue paper breakage provided by this utility model:

[0048] like Figures 1 to 6 As shown, the multi-segment cutting structure for tissue paper breakage according to this utility model includes multiple sets of cutting assemblies 2. Each set of cutting assemblies 2 is evenly distributed on the outer surface of a roller body 1 in the circumferential direction. The roller body 1 is a circular roller, defined as extending in the left-right direction, and rotates around its axis under the drive of a driving device. There are six sets of cutting assemblies 2 on the roller body 1. The cutting assemblies 2 are used in conjunction with other rollers to complete the breakage cutting of the tissue paper.

[0049] The following describes the cutter component 2, such as... Figures 1 to 3 As shown, the cutter assembly 2 includes a fixing member 3, a cutter 4, and a fixing member 5. The fixing member 3 includes multiple mounting grooves 31 arranged axially along the outer surface of the roller body 1. The mounting grooves 31 are stepped grooves and are inclined relative to the axis of the roller body 1. The mounting grooves 31 are inclined from left to right towards the axis of the roller body 1 in the radial direction, such that the left end of the right mounting groove 31 is higher than the right end of the left mounting groove 31. This allows for staggered installation of adjacent cutters 4 in the radial direction of the roller body 1. Each mounting groove 31 includes a cutter mounting groove 33 for mounting the cutter 4 and a fixing member mounting groove 32 for mounting the fixing member 5. Both the cutter mounting groove 33 and the fixing member mounting groove 32 are rectangular grooves. The fixing member mounting groove 32 is located above the cutter mounting groove 33 in the radial direction of the roller body 1.

[0050] The fixing element 5 is a pressure block 51, such as Figure 3 and Figure 6 As shown, the pressure block 51 includes a fixing part 52 and a pressing part 53. The fixing part 52 has a fixing hole 54 for mounting bolts. The fixing hole 54 is a countersunk hole to prevent the bolts installed on the pressure block 51 from affecting the cutting point of the paper towel. The fixing member mounting groove 32 has a mounting hole 34 corresponding to the pressure block 51. The pressure block 51 is fixedly mounted on the fixing member mounting groove 32 by bolts, fixing holes 54 and mounting holes 34. The cutter 4 is installed between the pressure block 51 and the cutter mounting groove 33. The lower side of the pressing part 53 has a downwardly protruding lower pressing platform 42, which is used to press the cutter 4 downward. The number of pressure blocks 51 on each fixing member mounting groove 32 is three, and each pressure block 51 is evenly distributed in the length direction of the fixing member mounting groove 32 to ensure that the cutter 4 is subjected to uniform force while increasing the pressing force of the cutter 4 in the cutter mounting groove 33. In other embodiments, the number of pressure blocks 51 in the fixing member mounting groove 32 is one or four.

[0051] Compared to the method of directly fixing the cutter 4 to the roller body 1 with bolts, the method of fixing the cutter 4 to the cutter mounting groove 33 using the pressure block 51 is more flexible. When maintenance personnel need to make fine adjustments to the installation position of the cutter 4, they only need to loosen the bolts on the corresponding pressure block 51, and then tighten the bolts after the adjustment is completed, without having to replace the cutter 4 or make overall adjustments to the cutter 4, thus enhancing the convenience of cutter 4 adjustment.

[0052] like Figure 4 and Figure 5 As shown, the cutter 4 includes a blade 43 and a pressure plate 41. The blade 43 is a rectangular plate structure, including a fixing end 44 and a cutting end 45. The fixing end 44 is located between the lower pressure table 42 and the cutter mounting groove 33, and is pressed onto the fixing mounting groove 32 by a pressure block 51, bolts, and the pressure plate 41. The length of the cutter 4 is greater than the length of the cutter mounting groove 33, and the mounting groove 32 is inclined from left to right towards the axis of the roller body 1 in the radial direction, so that the left end of the right cutter 4 can cover the right end of the left cutter 4 in the axial direction of the roller body 1, avoiding missed cuts on the paper towel and achieving continuous breakpoint cutting of the paper towel in the width direction. Each of the blades 43 has a serrated blade 46 at its cutting end 45, which is used to cooperate with other rollers to achieve breakpoint cutting of the paper towel. The serrated blades 46 of the covering parts of two adjacent cutters 4 overlap in shape along the radial direction of the roller body 1 to avoid incorrect breakage of the paper towel at the covering position of two adjacent cutters 4. The pressure plate 41 is a rectangular plate structure, which is glued and fixed to the fixed pressure end 44 of the blade 43. The pressure plate 41 is made of stainless steel, which can increase the friction coefficient between the cutter 4, the pressure block 51, and the cutter mounting groove 33 while the auxiliary pressure block 51 presses the blade 43. This increases the friction force between the cutter 4 and the pressure block 51, ensuring the stability of the cutter 4 installed in the cutter mounting groove 33.

[0053] Furthermore, since each mounting groove 31 is inclined relative to the axis of the roller body 1, the cutter 4 installed in the mounting groove 31 is also inclined relative to the axis of the roller body 1. When the roller body 1 rotates around the axis, the cutter 4 can always maintain point contact with the roller that cuts the tissue paper, thereby reducing the wear on the surface of the cutter 4 and extending its service life. In addition, the point contact engagement method also helps to improve the cutting accuracy of the tissue paper and improve the production quality of the tissue paper.

[0054] The working principle of the multi-segment cutting blade structure for tissue paper breakage according to this utility model is summarized as follows:

[0055] When the cutter 4 rotates with the roller 1, due to the inclined setting of the cutter 4 relative to the axis of the roller 1, the cutting end 45 of each cutter 4 cooperates with the corresponding roller protrusion to cut the paper towel raw material from bottom to top. The paper towel is cut at the break point under the squeezing action of the serrated blade 46 of the cutting end 45 of the blade 43 and the protrusion. When one of the cutters 4 on the roller 1 is damaged, the operator can remove the corresponding blade 43 by loosening the pressure block 51 that fixes the damaged cutter 4, and then replace it with a new cutter 4. Compared with the traditional one-piece cutter 4, the split cutter 4 of this utility model reduces the production cost and manufacturing difficulty of the cutter 4. At the same time, when the cutter 4 is damaged, the damaged cutter 4 can be replaced quickly, shortening the equipment downtime for maintenance, improving the overall production efficiency of the paper towel production equipment, and eliminating the need to replace all cutters 4 when replacing the cutter 4, thus reducing production maintenance costs.

[0056] Embodiment 2 of the multi-segment cutting structure for tissue paper breakage provided by this utility model:

[0057] Its main difference from Example 1 is:

[0058] In Example 1, the fixing component is a pressure block, and the cutter is fixed to the pressure block by bolts, which in turn drives the pressure block to press the cutter tightly.

[0059] In this embodiment, the fastener is a bolt, and the cutter is fixedly mounted on the cutter mounting slot by the bolt.

[0060] Embodiment 3 of the multi-segment cutting blade structure for tissue paper breakage provided by this utility model:

[0061] Its main difference from Example 1 is:

[0062] In Example 1, the blade and the pressure plate are fixed and bonded together as a single structure with glue.

[0063] In this embodiment, the pressure plate has a fixing pin, and the blade has a corresponding insertion hole on the fixing pin. The blade and the pressure plate are connected and fixed through the pin hole.

[0064] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0065] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
