Description

Technical Field

[0001] This invention relates to the field of paper tube packaging, and in particular to a paper positioning plate for packaging and its operation method. Background Technology

[0002] Paper tubes are commonly used spinning cores in various spinning mills. By winding the yarn around the outer circumference of the paper tube, they serve to hold and support the spinning process and transport the yarn to downstream customers. During transport, the yarn cakes formed by winding the yarn around the outer circumference of the paper tube experience relative friction and collisions between the yarn cakes, which can cause the wound yarn to loosen, resulting in defective yarn cakes that cannot be used by downstream customers. Therefore, after the yarn is wound into yarn cakes, it needs to be separated and packaged securely for storage and transportation.

[0003] Therefore, multi-layer fixing plates are often used in this operation. The size of the multi-layer fixing plates must be large enough to accommodate multiple stacks of silk cakes. When stacking silk cakes, two fixing plates are installed above and below each paper tube of each silk cake in each layer to secure them, preventing the silk cakes from tipping over and colliding and getting damaged. Fixing the silk cakes is actually achieved by fixing the ends of the paper tubes within the silk cakes. Currently, the main method is to cover the end face of the paper tube with a plastic cap to limit the displacement of the silk cakes, thereby preventing problems caused by friction and collision. However, the problem with using plastic caps is that these plastic caps only serve as separators, have no recycling benefits, and become white pollution after disposal, which is not environmentally friendly. Furthermore, the plastic caps themselves are expensive, and discarding them also results in cost waste. Summary of the Invention

[0004] In response to the shortcomings of the prior art, such as the lack of recycling benefits and environmental pollution caused by using plastic caps as fixing plates for filament rolls, the applicant provides a packaging paper positioning plate with a reasonable structure and its operation method. This plate can provide corrugated cardboard products to replace existing plastic caps, replacing plastic products that cause environmental pollution and cost waste with environmentally friendly materials. Moreover, the plate has a stable and reliable structure, achieving both economic and environmental benefits.

[0005] The technical solution adopted in this invention is as follows:

[0006] A packaging paper positioning board includes a first panel and a second panel connected together. The first panel has a plurality of first components, and the second panel has a plurality of second components. Each first component includes a left leaf and a right leaf, with a cut seam between them. The left and right leaves can be folded up. The front end of each second component has a snap-fit ​​protrusion. When the first and second panels are folded together, the second component presses down on the corresponding first component, causing the snap-fit ​​protrusion on the second component to combine with the left and right leaves to form a self-locking structure. The first components on the first panel and the second components on the second panel are arranged in an array.

[0007] As a further improvement to the above technical solution:

[0008] The first panel and the second panel are integrally formed and connected to each other, or connected to each other by means of a connector. The first panel and the second panel can be folded and unfolded into a single plane along the connection point.

[0009] The left-side sheet includes a connecting edge that is connected to the first panel body on the left and three other cutting edges that have cutting seams with the first panel body. The three cutting edges and the connecting edge form a trapezoidal structure. The length of the right cutting edge of the left-side sheet is greater than the length of the connecting edge. The right-side sheet adopts a structure symmetrical to the left-side sheet.

[0010] Hollow limiting holes are provided on the right cutting edge of the left leaf and the left cutting edge of the right leaf. The buckle protrusion on the second component is engaged with the hollow limiting holes on the left and right leaves.

[0011] The second component includes a connecting edge connected to the second panel body and three other cutting edges with cutting seams to the second panel body. The three cutting edges form a tongue structure. The tongue structure of the second component extends in a direction parallel to the cutting seams between the left and right leaf pieces on the first panel.

[0012] The snap-fit ​​protrusion is located at the front end of the tongue structure of the second component and is trapezoidal in shape, protruding from both sides of the body of the second component, forming snap-fit ​​slots on both sides of the body of the second component.

[0013] When the silk cake is fixed and supported, the left and right sheets that are supported in the self-locking structure form four ends as four support points, which limit and support the inside of the paper tube of the silk cake.

[0014] A method for operating a packaging paper positioning plate includes the following steps: Raw paperboard is cut to form a first panel and a second panel; the first and second panels are joined together; and a first component and a second component are formed on the first and second panels respectively, thus completing the packaging paper positioning plate. When the packaging paper positioning plate is used, the first and second panels are folded together along the central fold line, overlapping each other. The folded packaging paper positioning plate is then placed on a tooling fixture, with the second panel on top and the first panel on the bottom, and then... The stamping head performs a stamping operation on the second component. The second component is flipped downward by the stamping force, causing each second component to press down on the corresponding first component. Under the thrust of the second component, the left and right flaps of the first component flip up and open to both sides. As the second component continues to flip down, the left and right flaps continue to open until the latching protrusions on the second component reach the outside of the left and right flaps. At this time, the stamping head is retracted, and the latching protrusions on the second component retract and lock into the hollow limiting holes on the left and right flaps. The raised structure formed by the second component and the left and right flaps constitutes a self-locking structure.

[0015] As a further improvement to the above technical solution:

[0016] Furthermore, when the snap-fit ​​protrusion on the second component is engaged with the hollow limiting holes on the left and right leaf pieces, the snap-fit ​​protrusion protrudes to the left and right sides of the body of the second component, and the snap-fit ​​grooves formed on both sides of the body of the second component engage with the hollow limiting holes on the left and right leaf pieces.

[0017] When the silk cake is fixed and supported, the left and right sheets that are supported in the self-locking structure form four ends as four support points, which limit and support the inside of the paper tube of the silk cake.

[0018] The beneficial effects of this invention are as follows:

[0019] This invention utilizes a paper positioning plate, resulting in a stable and reliable structure. This avoids product defects during packaging and transportation, reducing the defect rate and improving efficiency. It also minimizes downstream customer issues and additional product losses. Furthermore, this product is environmentally friendly, producing no secondary pollution. Waste can be recycled and reused, or it can naturally degrade, resolving many adverse consequences that could arise from improper use of existing plastic products. Attached Figure Description

[0027] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] like Figures 1 to 6 As shown, the packaging paper positioning plate of the present invention includes a first panel 1 and a second panel 2 connected together. The first panel 1 and the second panel 2 are integrally formed and joined together, or joined together by means of a connector. A plurality of first components 3 are provided in the panel of the first panel 1, preferably arranged in an array. Correspondingly, a plurality of second components 4 are provided in the panel of the second panel 2, preferably arranged in an array. The number and position of the first components 3 and the second components 4 can be customized according to the size and quantity of the customer's paper roll. The connection between the first panel 1 and the second panel 2 is a fold line, and the two can be folded together along the fold line and unfolded into a single plane. The first components 3 on the first panel 1 and the second components 4 on the second panel 2 form a one-to-one correspondence. When the first panel 1 and the second panel 2 are folded together, the first components 3 and the corresponding second components 4 cooperate to form a self-locking structure, which is used to fix one end of the paper tube in the paper roll.

[0029] The first component 3 distributed on the first panel 1 is formed by cutting the body of the first panel 1. The first component 3 includes a left leaf 5 and a right leaf 6, with a cutting seam between the left leaf 5 and the right leaf 6. They are arranged opposite each other and can be folded and flipped up. The left leaf 5 includes a connecting edge connected to the body of the first panel 1 on the left and three other cutting edges with cutting seams to the body of the first panel 1. The three cutting edges and the connecting edge form a trapezoidal structure. The length of the right cutting edge of the left leaf 5 is greater than the length of the connecting edge. The connecting edge itself is an uncut part and has the function of connecting and folding. The three cutting edges are formed into a punched groove by punching, which is convenient for manufacturing. Correspondingly, the right leaf 6 includes a connecting edge connected to the body of the first panel 1 on the right and three other cutting edges with cutting seams to the body of the first panel 1. The three cutting edges and the connecting edge form a trapezoidal structure. The length of the left cutting edge of the right leaf 6 is greater than the length of the connecting edge. The right leaf 6 adopts a symmetrical structure with the left leaf 5.

[0030] A cutting seam is formed between the right cutting edge of the left leaf 5 and the left cutting edge of the right leaf 6. Corresponding hollow limiting holes 7 are provided on both the right cutting edge of the left leaf 5 and the left cutting edge of the right leaf 6. The hollow limiting holes 7 are positioning holes for the entire product and also serve as part of the self-locking structure.

[0031] The second component 4, distributed on the second panel 2, is cut from the body of the second panel 2. It includes a connecting edge connected to the body of the second panel 2 and three other cut edges with cut seams to the body of the second panel 2, forming a tongue structure. The protruding direction of the tongue structure of the second component 4 is parallel to the cut seams between the left leaf 5 and the right leaf 6 on the first panel 1. A snap-fit ​​protrusion 8 is provided at the front end of the tongue structure of the second component 4. The snap-fit ​​protrusion 8 is a trapezoidal structure, protruding from both sides of the body of the second component 4, forming snap-fit ​​slots on both sides of the body of the second component 4. The snap-fit ​​protrusion 8 of the second component 4, combined with the hollow limiting hole 7 of the first component 3, forms a self-locking structure. The dimensions are determined through strict calculation to ensure smooth locking when the double-layer cardboard is assembled.

[0032] Handrail slots 9 are provided on two identical sides of the first panel 1 and the second panel 2. Different sizes of handrail slots 9 are customized according to different packaging box sizes to facilitate the placement and removal of the positioning plate. The packaging paper positioning plate is made of environmentally friendly and biodegradable corrugated cardboard. Corrugated cardboard is used as the base paper for the entire positioning plate product. Corrugated cardboard of different thicknesses and strengths will be selected for processing according to the different sizes and weights of the silk cakes.

[0033] The operation method of the packaging paper positioning plate includes: the raw paperboard is cut to form a first panel 1 and a second panel 2, and a first component 3 and a second component 4 are formed on the first panel 1 and the second panel 2 respectively. Before use, the first panel 1 and the second panel 2 are joined together, and the first panel 1 and the second panel 2 are unfolded into a single plane. This state is the state of the packaging paper positioning plate when it is manufactured.

[0034] When the packaging paper positioning plate is used, the first panel 1 and the second panel 2 are folded together along the middle fold line, and the first panel 1 and the second panel 2 overlap. The folded packaging paper positioning plate is placed on a special tooling fixture with the second panel 2 on top and the first panel 1 on the bottom. Then, the punch head 15 is used to punch the second component 4. The second component 4 is flipped downward under the punching force, so that each second component 4 presses down on the corresponding first component 3. Under the pushing force of the second component 4, the first component 3 causes the left leaf 5 and the right leaf 6 to flip up and open to both sides. As the second component 4 flips downwards, the left leaf 5 and the right leaf 6 open continuously until the latching protrusion 8 on the second component 4 reaches the outside of the left leaf 5 and the right leaf 6. At this time, the stamping head 15 is retracted, and the latching protrusion 8 on the second component 4 retracts and locks into the hollow limiting hole 7 on the left leaf 5 and the right leaf 6. That is, the latching slots formed by the latching protrusion 8 on both sides of the body of the second component 4 are locked together with the hollow limiting hole 7 on the left leaf 5 and the right leaf 6. The raised structure formed by the second component 4 and the left leaf 5 and the right leaf 6 is a self-locking structure. The above process realizes the construction of a self-locking structure.

[0035] In the self-locking structure, the protruding left and right leaf pieces 5 and 6 form four ends, which act as four support points. When the silk roll is fixed and supported, the bottom of the paper tube inside the silk roll rests on the self-locking structure, and the inside of the paper tube is limited and supported by the four support points of the left and right leaf pieces 5 and 6. The self-locking structure is a combined self-locking mechanism created by folding a flat cardboard sheet in half and then creating a three-dimensional fold. This mechanism can position and limit the silk roll, and then maintain the stability of the positioning and limiting.

[0036] The packaging paper positioning plate is used in conjunction with a tooling fixture, which has a table support 10, preferably a square frame structure. At the top of the table support 10 is a horizontally arranged tooling table 11. A plurality of punching holes 14 are formed in the panel of the tooling table 11, preferably arranged in an array. The distribution of the punching holes 14 corresponds one-to-one with the self-locking structure of the packaging paper positioning plate.

[0037] A stamping plate 12 is hinged to one side of the tooling table 11. The stamping plate 12 can be opened or closed relative to the tooling table 11 around the hinge. An operating handle 13 is provided on one side of the stamping plate 12. The operating handle 13 protrudes from the stamping plate 12 and is perpendicular to the hinge edge between the stamping plate 12 and the tooling table 11. The operating handle 13 includes a connecting rod and a ball end cap. The connecting rod is fixedly installed on one side of the stamping plate 12.

[0038] A punch head 15 is provided on the lower surface of the stamping plate 12, corresponding to the punch holes 14 one by one. The punch head 15 is vertically arranged on the lower surface of the stamping plate 12. The punch head 15 includes a straight rod and a ball extrusion head connected to the stamping plate 12 through the straight rod. The punch head 15 can extend into the corresponding punch hole 14.

[0039] To save costs, the tooling fixtures can be manual, or to improve production efficiency, they can be automated mechanical fixtures, which are dedicated, customized equipment.

[0040] In the implementation of this invention, relevant data is obtained by measuring the inner and outer diameters of the silk cake paper tube. Based on this data, the punching groove type and hollow limiting hole 7 of the first component 3 and the second component 4 are designed. After the hollow limiting hole 7 is positioned, the position and size of the snap-fit ​​groove on the second component 4 are determined. After confirming the relevant information of the snap-fit ​​groove on the second component 4, the data calculation of the three-dimensional combination self-locking structure of the hollow limiting hole 7 and the snap-fit ​​groove on the second component 4 is performed to determine the final processing dimensions. The planar semi-finished product of the positioning plate is processed using a punching die. The planar semi-finished product is then three-dimensionally processed using a special tooling fixture to produce the final product that can support the silk cake.

[0041] During operation, the positioning plates of the finished product are used for packaging the wire cakes, enabling the positioning and limiting of the wire cakes, preventing friction and collisions between them, ensuring product quality during transportation, and thus improving the product yield. Corrugated cardboard is a biodegradable and environmentally friendly material that will not have an adverse impact on the environment during turnover or after disposal, and its cost is lower than that of the original plastic caps, achieving both added value and environmental friendliness.

[0042] The above description is an explanation of the present invention and not a limitation thereof. The present invention can be modified in any form without departing from its spirit.
