Description

Technical Field

[0001] The invention relates to the field of electronic product accessories, and in particular to a paper towel folding and cutting method. Background Art

[0002] At present, when producing paper towels, it is necessary to first stack several sheets of paper towels into long strips, and then use a cutter to cut the long strips into several independent short strips of paper towels, and then package them after cutting into short strips of paper towels, wherein the cutting is performed by a cutter. In the process of using a cutter to cut the long strips of paper towels into short strips, the cutter will constantly rub against the paper towels, and the cutter will be covered by paper sheets during the cutting process. In this state, the temperature of the cutter will rise, and the increase in the temperature of the cutter will cause the plastic fibers (PP fibers or PE fibers) in the paper towels to melt. After the plastic fibers melt and solidify, black particles will be formed. The presence of these black particles will cause the user to feel more uncomfortable when using the paper towels. Summary of the invention

[0003] In view of the above problems, the present invention proposes a paper towel folding and cutting method, which comprises firstly opening through holes arranged in a linear shape on a single piece of paper towel, then folding the single piece of paper towel into a long strip, and finally tearing the long strip of paper towel into several short strips of paper towel by a tearing method, and no black particles are generated in the whole process.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A paper towel folding and cutting method comprises the following steps:

[0006] a hole cutting step, in which through holes are formed on the single paper towel sheet, and the through holes are distributed in a linear manner on the single paper towel sheet, and the through holes form a fracture line on the single paper towel sheet;

[0007] A stacking step, stacking a plurality of single paper towel sheets with through holes formed therein into a long strip of paper towel, wherein the fracture lines on the paper towel sheets form fracture surfaces;

[0008] The tearing step comprises: using a tearing mechanism to clamp the long strip of paper towel and tear the long strip of paper towel into a plurality of independent short strips of paper towel along the fracture surface.

[0009] In the paper towel folding and cutting method, first, a through hole is opened in a single paper towel sheet before being stacked into a long strip of paper towel. When the through hole is opened in the single paper towel sheet, the problem of the opening tool causing excessive temperature due to friction and poor heat dissipation will not occur. Therefore, when the single paper towel sheet is opened, the problem of the plastic fiber in the paper towel melting and then solidifying due to the blade will not occur, so no black particles will be generated.

[0010] After the through holes are opened, the single paper towel pieces are stacked to form a long strip of paper towel. The long strip of paper towel is composed of several single paper towel pieces. The fracture lines on the single paper towel pieces are in an overlapping state to form a fracture surface. The existence of the fracture surface allows the entire long strip of paper towel to be torn off. When torn off, the long strip of paper towel is torn into two parts along the fracture surface.

[0011] In summary, in this tearing method, through holes arranged in lines are opened on a single piece of paper towel, and then the single piece of paper towel is folded into a long strip, and finally the long strip of paper towel is torn into several short strips by a tearing method, and no black particles are generated in the whole process.

[0012] Optionally, the distances between two adjacent through holes on a single paper towel sheet are equal.

[0013] Specifically, the through holes on the single paper towel are rolled and opened by a round roller with a cutting edge, so the distance between two adjacent through holes on the single paper towel piece is equal.

[0014] Optionally, there are multiple break lines on a single paper towel piece, and the number of break surfaces on the long strip of paper towel is equal to the number of break lines on the single paper towel piece.

[0015] The fracture lines on a single piece of tissue paper can be opened as needed, and the fracture lines are in a parallel state. If a single piece of tissue paper needs to be torn into two parts, only one fracture line needs to be opened. If a single piece of tissue paper needs to be torn into three parts, two fracture lines need to be opened.

[0016] Optionally, the tearing mechanism includes a first clamping frame, a second clamping frame, a base and a telescopic rod, the second clamping frame is slidably arranged on the base, the first clamping frame is arranged on one side of the base, one end of the telescopic rod is fixed to the base, and the other end of the telescopic rod is cooperated with the second clamping frame, the first clamping frame is provided with a first main clamping cylinder and a first auxiliary clamping cylinder, the first main clamping cylinder and the first auxiliary clamping cylinder are both provided with clamping plates, the second clamping frame is provided with a second main clamping cylinder and a second auxiliary clamping cylinder, and the second main clamping cylinder and the second auxiliary clamping cylinder are both provided with clamping plates.

[0017] Optionally, the tearing mechanism further includes a first conveyor belt and a second conveyor belt, wherein the first conveyor belt is rotatably disposed on the first clamping frame, and the second conveyor belt is rotatably disposed on the second clamping frame.

[0018] Optionally, a suspension platform is provided on the second clamping frame, and a photoelectric detection probe is provided on the suspension platform.

[0019] Optionally, a guide rail is provided on the base platform, and a slider is provided on the second clamping frame, and the slider is slidably matched with the guide rail.

[0020] Optionally, the first main clamping cylinder, the first auxiliary clamping cylinder, the second main clamping cylinder and the second auxiliary clamping cylinder are in the same plane.

[0023] The beneficial effect of the present invention is that through holes arranged in a linear shape are firstly opened on a single piece of paper towel, and then the single piece of paper towel is folded into a long strip, and finally the long strip of paper towel is torn into a plurality of short strips of paper towel by a tearing method, and no black particles are generated in the whole process.

[0052] Example 2

[0053] A paper towel folding and cutting method based on the tearing mechanism shown in the above embodiment 1,

[0054] Combined with Figure 1 , Attachment Figure 2 And attached Figure 3 As shown, the following steps are included.

[0055] A paper towel folding and cutting method comprises the following steps:

[0056] S1 (hole cutting step), opening through holes 1701 on the single paper towel piece 17, and the through holes 1701 are distributed in a linear manner on the single paper towel piece 17, and the through holes 1701 form a fracture line 17011 on the single paper towel piece 17; this process can be referred to in the attached Figure 1 In, attached Figure 1 When the middle round roller 18 rolls the single tissue piece 17 , its cutting edge 1801 will cut through holes 1701 distributed in a linear shape on the single tissue piece 17 , but the cutting edge 1801 on the round roller 18 will not completely cut the single tissue piece 17 .

[0057] S2 (stacking step), stacking a plurality of single paper towel sheets 17 with through holes 1701 to form a long strip of paper towel, the fracture lines 17011 on the paper towel sheets form a fracture surface; the fracture surface is composed of a plurality of fracture lines 17011, and the state of the single paper towel sheets 17 after being stacked to form a long strip of paper towel is as shown in the attached figure Figure 2 as shown in .

[0058] S3 (tearing step), use the tearing mechanism as shown in Example 1 to clamp the long strip of paper towel. When clamping, four clamping plates clamp the long strip of paper towel from both sides of the fracture surface respectively, among which the two clamping plates on the left side of the fracture surface are installed on the first main clamping cylinder and the first auxiliary clamping cylinder, and the two clamping plates on the right side of the fracture surface are installed on the second main clamping cylinder and the second auxiliary clamping cylinder. When tearing, the two clamping plates on the right side of the fracture surface move to the right, and the two clamping plates on the left side of the fracture surface remain stationary, so that the long strip of paper towel is torn into several independent short strips of paper towel along the fracture surface.

[0059] In the present paper towel folding and cutting method, first, a through hole 1701 is opened in a single paper towel piece 17 before being stacked into a long strip of paper towel. When the through hole 1701 is opened in the single paper towel piece 17, there will be no problem of the opening tool overheating due to friction and poor heat dissipation. Therefore, when the single paper towel piece 17 is opened, there will be no problem of the plastic fibers in the paper towel melting and then solidifying due to the blade, so no black particles will be generated.

[0060] After the through hole 1701 is opened, the single paper towel pieces 17 are stacked to form a long strip of paper towel. The long strip of paper towel is composed of several single paper towel pieces 17. The fracture lines 17011 on the single paper towel pieces 17 are in an overlapping state to form a fracture surface. The existence of the fracture surface allows the entire long strip of paper towel to be torn off. When torn off, the long strip of paper towel is torn into two parts along the fracture surface.

[0061] In summary, in this tearing method, through holes 1701 arranged in lines are opened on a single piece of paper towel, and then the single piece of paper towel is folded into a long strip, and finally the long strip of paper towel is torn into several short strips by a tearing method, and no black spots are generated in the whole process.

[0062] In this embodiment, the distance between two adjacent through holes 1701 on a single paper towel sheet 17 is equal.

[0063] Specifically, the through holes 1701 on the single paper towel are rolled open by a round roller 18 with a cutting edge 1801 , so the distances between two adjacent through holes 1701 on the single paper towel sheet 17 are equal.

[0064] In this embodiment, there is only one fracture line 17011 on a single tissue piece 17, and the number of fracture surfaces on the long tissue strip is equal to the number of fracture lines 17011 on the single tissue piece 17. In other equivalent embodiments, there may be more than one fracture line 17011 on a single tissue piece 17.

[0065] The breaking line 17011 on the single paper towel piece 17 can be opened as needed, and the breaking line 17011 is in a parallel state. If the single paper towel piece 17 needs to be torn into two parts, only one breaking line 17011 needs to be opened. If the single paper towel piece 17 needs to be torn into three parts, two breaking lines 17011 need to be opened.

[0066] In summary, the cutting method disclosed in this embodiment is actually a method of first cutting, then folding and finally pulling apart.

[0067] What needs to be specially explained in the present embodiment is that, currently, single-piece paper towel sheets also need to be clamped by circular rollers in the process of stacking into long strips of paper towel sheets. The present method only opens a cutting edge on the circular roller of the guide clamp, so that the circular roller completes the process of cutting holes in the single-piece paper towel sheets during the process of guiding and clamping. After being guided and clamped by the circular roller, the single-piece paper towel sheets will be stacked together to form long strips of paper towel.

[0068] The above-described embodiments only express some embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for those skilled in the art, it is still possible to modify the technical solutions recorded in the above-mentioned embodiments, or to replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
