Description

Technical Field

[0001] The utility model relates to the technical field of toilet paper slitting, and more specifically, to a toilet paper slitting device. Background Art

[0002] Toilet paper is a paper product mainly used for daily hygiene cleaning, usually made of plant fibers (such as wood pulp, bamboo pulp, sugarcane bagasse, etc.). According to different needs, toilet paper has different types and specifications, such as single-roll paper, boxed tissue paper, wet wipes, etc. Among them, toilet paper slitting refers to the process of cutting the wide-width base paper produced on a large scale into standard sizes suitable for use through a slitting device.

[0003] At present, the cutting knives on the slitting device are all fixedly installed and cannot change the state of the cutting knives to adapt to different slitting requirements. That is, when it is necessary to slit different numbers of segments, the corresponding cutting knives cannot be adjusted. When the number of slitted segments is reduced, the redundant cutting knives will affect the slitting work of the toilet paper. Generally, only the cutting knives here can be removed and reinstalled when needed later. The operation is cumbersome and complex, consuming a lot of time and labor, with low work efficiency. Moreover, after removal, the cutting knives will occupy stacking space and multiple disassembly and installation will affect their service performance and service life.

[0004] Therefore, it is necessary to provide a toilet paper slitting device to solve the above technical problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a toilet paper slitting device to solve the above technical problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A toilet paper slitting device includes a mounting frame and a receiving roller rotatably arranged thereon, and further includes:

[0008] A fixed rod is arranged on the mounting frame, and a plurality of slitting mechanisms are detachably installed on the fixed rod. The slitting mechanism includes:

[0009] A U-shaped clamping block is cooperatively connected with the fixed rod. A transfer plate is arranged on the U-shaped clamping block, and a horizontal blocking block and a vertical blocking block are arranged on the transfer plate;

[0010] A connecting rod is rotatably arranged on the transfer plate, and a cutting knife is installed on the connecting rod;

[0011] A limiting mechanism is arranged on the transfer plate for limiting the position of the connecting rod.

[0012] Further, a bracket is arranged at the end of the connecting rod, the cutting knife is rotatably arranged on the bracket through a rotating shaft, and a driving member for driving the cutting knife to rotate is installed on the bracket.

[0013] Furthermore, the limiting mechanism includes:

[0014] A first elastic member, one end of which is arranged on the adapter plate and the other end of which is provided with a pull plate;

[0015] A limiting rod, one end of which is connected to the pull plate and the other end of which movably penetrates through the adapter plate and extends to the other side thereof.

[0016] Furthermore, a perforation is formed on the fixed rod, a fixing hole adapted to the perforation is formed on the U-shaped clamping block, and the fixing hole is fixed to the fixed rod through cooperation with a bolt.

[0017] Furthermore, a protective cover is further arranged on the bracket, and a plurality of annular avoidance grooves are formed on the receiving roller.

[0018] Furthermore, support plates are arranged on the outer walls on both sides of the protective cover, a wheel frame is arranged on the support plates, and a pressing wheel is rotatably arranged on the wheel frame.

[0019] Furthermore, a sleeve is arranged on the support plate, a hidden cavity is formed in the sleeve, an inner column is slidably arranged in the hidden cavity, the outer end of the inner column is connected to the wheel frame, and a second elastic member is arranged between the inner column and the inner wall of the hidden cavity.

[0020] Furthermore, a moving groove is formed on the inner wall of the hidden cavity, and a slider connected to the inner column is slidably arranged in the moving groove.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] 1. In this solution, when it is necessary to cut toilet paper into different segments, for example, when one segment needs to be reduced, the connecting rod and the cutter on the slitting mechanism at this position are turned into a vertical state, and then limited by the limiting mechanism, that is, the slitting mechanism does not perform cutting operations on the toilet paper. Therefore, the state of each slitting mechanism can be changed to adapt to different slitting requirements. The whole operation is simple and convenient, reducing the time and labor cost, with high work efficiency. It can be easily adjusted according to the different segments to be slit, and has strong practicability. Moreover, it avoids the situation that the current cutter removal will occupy more external space or cause loss, and at the same time, it can also reduce the impact on the use performance and service life of the cutter due to repeated removal.

[0023] 2. In this solution, when the toilet paper is cut by the cutter, the pressing wheels on both sides of the protective cover will press on the toilet paper on both sides of the cutting position. Through the pressing wheels, it can greatly avoid the situation that the toilet paper will shift during cutting, greatly improving the stability of the moving slitting of the toilet paper, making the slitting more uniform, and improving the slitting production quality of the toilet paper.

[0024] 3. In this solution, when the pressing wheel presses on the toilet paper, through the cooperation of the inner column and the second elastic member, the phenomenon that the pressing wheel makes hard contact with the toilet paper or the receiving roller can be avoided, and a certain buffering effect can be achieved, preventing damage to the toilet paper. At the same time, when there are some uneven parts on the receiving roller, the pressing wheel will also make adaptive expansion and contraction to reduce the impact on the toilet paper or the receiving roller; when cutting toilet paper with different thicknesses, the pressing wheel will also make adaptive adjustments at this time, with a wider application range.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0036] Please refer to Figure 1-8 , a toilet paper cutting device, including a mounting frame 1 and a receiving roller 2 rotatably disposed thereon, and further including: a fixed rod 3 disposed on the mounting frame 1, and a plurality of cutting mechanisms 4 detachably mounted on the fixed rod 3. The cutting mechanism 4 includes: a U-shaped clamping block 41, cooperatively connected with the fixed rod 3, a transfer plate 42 is provided on the U-shaped clamping block 41, and a horizontal blocking block 43 and a vertical blocking block 44 are provided on the transfer plate 42; a connecting rod 45 rotatably disposed on the transfer plate 42, and a cutter 46 is mounted on the connecting rod 45; a limiting mechanism 47 disposed on the transfer plate 42 for restricting the position of the connecting rod 45.

[0037] During use, first operate the limiting mechanism 47 on each cutting mechanism 4 to release the restriction and fixation on the connecting rod 45, then rotate the connecting rod 45 and the cutter 46 so that the connecting rod 45 and the cutter 46 are converted from a horizontal state to a vertical state, and then use the limiting mechanism 47 to restrict the connecting rod 45 and the cutter 46 at this position; then pass the wide-width original toilet paper through other guide rollers so that the toilet paper is laid on the receiving roller 2 and passes through its upper end surface, and an external device drives the toilet paper to move. At this time, the toilet paper will not be interfered by the cutter 46 above the receiving roller 2, that is, it avoids the inconvenient operation that the toilet paper will be cut by the cutter 46 when being placed on the receiving roller 2, and makes the installation of the toilet paper more convenient.

[0038] After adjusting the positions of the respective slitting mechanisms 4 on the fixed rod 3, the restriction of the limiting mechanism 47 on the vertically positioned connecting rod 45 and the cutter 46 is then released. The connecting rod 45 and the cutter 46 are then rotated to a horizontal state, and the connecting rod 45 and the cutter 46 at this time are fixed by the limiting mechanism 47. Then, by rotating the cutter 46, the toilet paper can be cut. The toilet paper can be cut into multiple segments by the cutters 46 on the multiple slitting mechanisms 4. When it is necessary to cut toilet paper into different numbers of segments, for example, when one segment needs to be reduced, that is, the cutting of one slitting mechanism 4 is reduced. As described above, at this time, the connecting rod 45 and the cutter 46 on the slitting mechanism 4 at this position are rotated to a vertical state, and then they are restricted by the limiting mechanism 47, that is, this slitting mechanism 4 does not perform the cutting operation on the toilet paper, and the other slitting mechanisms 4 perform the slitting operation. Thus, the states of the respective slitting mechanisms 4 can be changed to adapt to different slitting requirements, avoiding the current method of generally removing the cutter 46 of the slitting mechanism 4. The whole operation is simple and convenient, reducing the time and labor spent, with high working efficiency. It can be conveniently adjusted according to the different numbers of segments to be slit, and has strong practicability. Moreover, it avoids the situation that the current removal of the cutter 46 will occupy more external space or cause loss, and at the same time can also reduce the impact on the service performance and life of the cutter 46 due to repeated removal.

[0039] In this embodiment, preferably, please refer to Figure 2-4 , a bracket 5 is provided at the end of the connecting rod 45. The cutter 46 is rotatably arranged on the bracket 5 through a rotating shaft. A driving member 6 for driving the cutter 46 to rotate is installed on the bracket 5. The driving member 6 in this application adopts a servo motor. After the driving member 6 is started, it can drive the cutter 46 to rotate, and the toilet paper can be better cut by the rotating cutter 46.

[0040] In this embodiment, preferably, please refer to Figure 2-4 and Figure 7 , the limiting mechanism 47 includes: a first elastic member 471, one end of which is arranged on the adapter plate 42, and the other end is provided with a pull plate 472; a limiting rod 473, one end of which is connected to the pull plate 472, and the other end movably penetrates the adapter plate 42 and extends to the other side thereof. The first elastic member 471 in this application adopts a spring.

[0041] As Figure 2-4, the horizontal connecting rod 45 will be restricted by the cross stop 43 and the limit rod 473. When it is necessary to convert the states of the connecting rod 45 and the cutting knife 46, pulling the pull plate 472 outwards at this time will drive the limit rod 473 to move and stretch the first elastic member 471. When the limit rod 473 moves away from above the connecting rod 45, the connecting rod 45 and the cutting knife 46 can be driven to rotate at this time. When it is rotated to the vertical state, the pull plate 472 is released at this time, and the limit rod 473 will be driven to move back to the initial state by the resilience of the first elastic member 471. At this time, the two sides of the connecting rod 45 are restricted by the limit rod 473 and the vertical stop 44, such as Figure 7 .

[0042] In this embodiment, preferably, please refer to Figure 1-4 and Figure 7-8 . A through hole 7 is formed in the fixed rod 3, and a fixing hole 8 adapted to the through hole 7 is formed in the U-shaped block 41. The fixing hole 8 is fixed to the fixed rod 3 through the cooperation of a bolt. When installing the slitting mechanism 4 on the fixed rod 3, by clamping the U-shaped block 41 onto the fixed rod 3 and driving the U-shaped block 41 to move along the fixed rod 3, after the slitting mechanism 4 moves to the designated position, by passing the bolt through the fixing hole 8 and the through hole 7, and then fixing the U-shaped block 41 to the fixed rod 3 through the cooperation of a gasket and a nut at the bottom of the fixed rod 3. Similarly, when it is necessary to move the position of the slitting mechanism 4 or remove it, just unscrew the bolt. The installation, removal and position adjustment of the slitting mechanism 4 are very convenient. The distance between the slitting mechanisms 4 can be adjusted according to the different section distances of the toilet paper, with a large application range and meeting the use requirements.

The second elastic member 17 in this application adopts a spring or a combination of a spring and a damper. When the pressing wheel 13 presses on the toilet paper, through the cooperation of the inner column 16 and the second elastic member 17, the phenomenon that the pressing wheel 13 is in hard contact with the toilet paper or the receiving roller 2 can be avoided, and a certain buffering effect can be achieved, avoiding damage to the toilet paper. At the same time, when there are some uneven parts on the receiving roller 2, the pressing wheel 13 will also make an adaptive expansion and contraction to reduce the impact on the toilet paper or the receiving roller 2; at the same time, when cutting toilet paper with different thicknesses, the pressing wheel 13 will also make an adaptive adjustment at this time, and the applicable range is larger.
