Description

Technical Field

[0001] The utility model relates to the technical field of paper towel production equipment, in particular to a paper towel C-shaped folding tool. Background Art

[0002] Paper towels are a common daily necessity for modern people. In my country's toilet paper standards, there are many folding methods for paper towels with different focuses. For example, C-fold, J-fold, M-fold, V-fold, W-fold or Z-fold. These configurations are formed by folding the toilet paper base paper web in a specified letter shape. Some of them form intertwined toilet paper products. The folds can be formed in the longitudinal direction, transverse direction or in a vertical and horizontal interlaced manner.

[0003] V-shaped folded tissue paper is often used in daily life, restaurants or offices, and includes a packaging bag body and tissue paper stacked in the packaging bag body. When the V-shaped folded tissue paper is taken out, the next sheet of paper will be exposed outside the packaging bag, so as to facilitate the next use.

[0004] For example, in the patent document with the patent number CN201880006421.1 and the name of "Film-wrapped Tissue Paper", the disclosed film-wrapped tissue paper stack in which a part of the tissue paper exposed from the outlet is easily in an upright state adopts a typical V-shaped folding design. The following film-wrapped tissue paper solves the problem: it is formed by packaging a bundle of pull-out tissue paper with a resin packaging film, wherein the perforated line for forming the outlet is annular and formed along the long side direction, and the edge of the outlet formed by the splitting of the perforated line for forming the outlet has a guide edge portion, and the guide edge portion moves each side edge portion of the bundle of tissue paper in the long side direction toward the short side direction of the bundle.

[0005] Compared with V-shaped folded tissue paper, the C-shaped folded tissue paper does not interfere with each other, and the second sheet will not be taken out when taking it out, preventing exposure to contamination and bacterial growth. It is a special design and treatment for sensitive users.

[0006] Therefore, in order to improve the production efficiency and product quality of toilet paper with a C-type folding structure and to meet market demand, it is necessary to improve and develop the production equipment for C-type folding toilet paper. Utility Model Content

[0007] In order to solve the problem that tissue paper on the market currently generally has a V-shaped stacking structure, when the user pulls out a piece of tissue paper, the next piece of paper will be pulled out, making it exposed outside the packaging bag. The paper is easily contaminated or even breeds bacteria due to exposure to the outside world, making it unusable for susceptible people. In this way, a C-shaped folding tool for tissue paper is provided.

[0008] The C-type folding tool for paper towels includes a tool shell, which includes a positioning guide groove, a vertical folding groove and a pressing and folding groove connected in sequence. The width of the positioning guide groove is equal to that of toilet paper, and the width of the vertical folding groove gradually decreases from the positioning guide groove to the pressing and folding groove. Vertical side panels are symmetrically arranged on both sides of the vertical folding groove, and the vertical side panels and the bottom of the vertical folding groove are surrounded in a funnel shape. The left and right sides of the pressing and folding groove are parallel to each other. A guide cover plate is installed on the top of the tool shell from the end of the positioning guide groove to the front end of the pressing and folding groove, and the guide cover plate gradually tilts downward from the end of the positioning guide groove to the front end of the pressing and folding groove.

[0009] Furthermore, positioning bolts are arranged on the left and right sides of the end of the guide cover plate, and vertical through grooves are opened on the left and right sides of the tooling shell corresponding to the positioning bolts, and the positioning bolts are inserted into the vertical through grooves.

[0010] Furthermore, a paper pressing baffle is arranged above the corresponding positioning guide groove, the vertical folding groove and the pressing and folding groove in the tooling shell, and connecting gaps are arranged between the side edge of the paper pressing baffle and the vertical side plate, and between the side edge of the paper pressing baffle and the side wall of the pressing and folding groove, and the width of the connecting gap is greater than the thickness of the toilet paper.

[0011] Furthermore, a positioning seat is provided on the top of the tooling shell, a lifting connecting rod is vertically connected in series in the positioning seat, and the paper pressing baffle is installed at the bottom of the lifting connecting rod.

[0012] Furthermore, a vertical nut is installed on the positioning seat, the lifting connecting rod is threadedly connected in series with the vertical nut, and the bottom of the lifting connecting rod is connected to the paper pressing baffle through a rotating bearing.

[0013] Furthermore, arc-shaped chamfered grooves are provided at the connection between the inner side of the bottom surface of the positioning guide groove and the left and right side walls.

[0014] Furthermore, the tooling shell is placed vertically downward, the positioning guide groove is arranged at the top of the tooling shell, and the pressing and folding groove is arranged at the bottom of the tooling shell.

[0032] like Figures 1 to 5 As shown, this embodiment provides a C-type folding tool for paper towels, including a tool shell 1, wherein the tool shell 1 includes a positioning guide groove 101, a vertical folding groove 102 and a pressing and folding groove 103 connected in sequence, the width of the positioning guide groove 101 is equal to that of the toilet paper 6, the width of the vertical folding groove 102 gradually decreases from the positioning guide groove 101 to the pressing and folding groove 103, and vertical side panels 1021 are symmetrically arranged on both sides of the vertical folding groove 102, and the vertical side panels 1021 and the bottom of the vertical folding groove 102 are surrounded in a funnel shape, and the left and right sides of the pressing and folding groove 103 are parallel to each other, and a guide cover plate 2 is installed on the top of the tool shell 1 from the end of the positioning guide groove 101 to the front end of the pressing and folding groove 103, and the guide cover plate 2 gradually tilts downward from the end of the positioning guide groove 101 to the front end of the pressing and folding groove 103.

[0033] During the processing, the toilet paper 6 conveyed by the upstream equipment enters the tooling housing 1 and passes through the positioning guide groove 101, the vertical folding groove 102 and the pressing folding groove 103 in sequence. First, the positioning guide groove 101 clamps the two sides of the toilet paper 6 to fix the forward direction of the toilet paper 6. Then the toilet paper 6 enters the vertical folding groove 102, and the two sides of the toilet paper 6 are supported by the vertical side plates 1021 that shrink in a funnel shape and tilted and folded. Finally, the toilet paper 6 continues to move forward, and the tilted front ends of the toilet paper 6 on both sides contact the bottom surface of the downwardly inclined guide cover plate 2, so that the tilted parts of the toilet paper 6 on both sides are folded inward, and overlapped on the middle part of the toilet paper 6 under the guidance of the gradually downwardly inclined guide cover plate 2, so that the toilet paper 6, which was originally in the shape of "I", becomes a 90° tilted "C" shape because the two sides are symmetrically overlapped inward.

[0034] Positioning bolts 201 are arranged on the left and right sides of the end of the guide cover plate 2, and vertical through slots 7 are provided on the left and right sides of the tool housing 1 corresponding to the positioning bolts 201, and the positioning bolts 201 are inserted into the vertical through slots 7. The height of the end of the guide cover plate 2 can be adjusted up and down on the vertical through slots 7 to adapt to toilet paper of different thicknesses.

[0035] A paper pressing baffle 3 is provided above the corresponding positioning guide groove 101, the vertical folding groove 102 and the pressing and folding groove 103 in the tool housing 1, and a connecting gap 301 is provided between the side edge of the paper pressing baffle 3 and the vertical side plate 1021, and between the side edge of the paper pressing baffle 3 and the side wall of the pressing and folding groove 103, and the width of the connecting gap 301 is greater than the thickness of the toilet paper 6. The paper pressing baffle 3 makes the middle part of the toilet paper 6 that does not need to be folded always fit the bottom of the tool housing 1, so as to prevent the middle part of the toilet paper 6 from being lifted and displaced by the folded parts on both sides, thereby improving the folding flatness of the toilet paper 6. Specifically, when the toilet paper 6 enters the vertical folding groove 102, the two sides of the toilet paper 6 are blocked by the vertical side panels 1021 and folded 90 degrees, and pass through the connecting gap 301 to the top of the paper pressing baffle 3. Then, the two folded sides of the toilet paper 6 are pressed against the upper side of the paper pressing baffle 3 by the upper side of the paper pressing baffle 3 and the downward inclined bottom of the guide cover plate 2, so that the toilet paper 6 forms a C-shaped fold.

[0036] A positioning seat 4 is provided at the top of the tool housing 1, and a lifting connecting rod 401 is vertically connected in series in the positioning seat 4, and the paper pressing baffle 3 is installed at the bottom of the lifting connecting rod 401. A vertical nut 402 is installed on the positioning seat 4. The lifting connecting rod 401 is threadedly connected in series in the vertical nut 402, and the bottom of the lifting connecting rod 401 is connected to the paper pressing baffle 3 through a rotating bearing (not shown in the figure). The distance between the paper pressing baffle 3 and the bottom of the inner side of the tool housing 1 can be adjusted by rotating the lifting connecting rod 401 to adapt to different toilet paper thicknesses.

[0037] The inner side of the bottom surface of the positioning guide groove 101 and the connection between the left and right side walls are both provided with arc chamfered grooves 5. The arc chamfered grooves 5 can guide the two sides of the toilet paper 6 to fold to the sides after the toilet paper 6 enters the positioning guide groove 101, so as to prevent the toilet paper 6 from being stuck in the tooling housing 1 and unable to move forward.

[0038] The tool housing 1 is placed vertically downward, the positioning guide groove 101 is arranged at the top of the tool housing 1, and the pressing and folding groove 103 is arranged at the bottom of the tool housing 1. The tool housing 1 arranged vertically downward allows the toilet paper 6 to pass through the positioning guide groove 101, the vertical folding groove 102 and the pressing and folding groove 103 in sequence under the action of gravity, which can improve the processing smoothness of the toilet paper 6 when performing C-shaped folding compared to the tool housing 1 placed flat.

[0039] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementation modes. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
