Description

Technical Field

[0001] This invention belongs to the field of packaging carton production, specifically relating to a pressure roller for explosion-proof lines of carton and its preparation method. Background Technology

[0002] At present, my country's packaging industry has formed a relatively complete packaging industry system with complete categories such as materials, products, machinery, packaging printing, design and scientific research. The packaging products with the highest annual output in the world are corrugated cardboard, plastic woven bags, composite flexible packaging and metal drums. Among them, the output of corrugated cardboard ranks second in the world.

[0003] Currently, the packaging industry mainly suffers from problems such as low-level repetitive construction, low quality, and low technological content. At the same time, the rate of defective and scrapped cartons increases due to bursting during the carton production process.

[0004] Therefore, there is an urgent need in this field for an online production technology to prevent cardboard boxes from bursting, in order to improve the yield rate of cardboard boxes and reduce production costs. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] Therefore, the purpose of this invention is to overcome the shortcomings of the prior art and provide a pressure roller for explosion-proof lines for carton.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pressure roller for an explosion-proof line for cardboard boxes, comprising,

[0009] The main material of the pressure roller (100), the pressure line (200), and the groove strip (300); among which,

[0010] The main material (100) of the pressure roller includes a long side (101) and a short side (102);

[0011] The pressure line (200) includes pressure line (201) and pressure line (202). The pressure line (201) and pressure line (202) are fixedly arranged on the main material (100) of the pressure roller with equal length and parallel to each other, and are parallel to the long side (101).

[0012] The slot strip (300) is fixedly set on the long side (101).

[0013] As a preferred embodiment of the pressing roller of the present invention, the main material (100) of the pressing roller is a film material made of high-viscosity PET or PCT material with high temperature resistance and high performance and not easily deformed.

[0014] In a preferred embodiment of the pressure roller of the present invention, the pressure line (200) is a silicone rubber strip with grooves.

[0015] In a preferred embodiment of the pressure roller of the present invention, the groove strip is made of ordinary silicone rubber.

[0016] As a preferred embodiment of the pressure roller of the present invention, the plastic film material includes high-viscosity PET with a viscosity range of 0.8 to 1.1 dl / g and PCT with a melting point greater than 280°C.

[0017] In a preferred embodiment of the pressure roller of the present invention, the mass ratio of PET to PCT is 1:9 to 9:1.

[0018] As a preferred embodiment of the pressure roller of the present invention, the pressure line is made of silicone rubber as raw material, with a hardness of 20 to 60 degrees and a tensile strength of 5 to 10 MPa.

[0019] In a preferred embodiment of the pressure roller described in this invention, the dimensions and spacing of the pressure lines are designed according to the size of the cartons being produced. Combined with the production line process, the size range of the produced cartons is 0.2*0.2~2*5m. 2 The width of the embossing groove is designed according to the size of the carton, and the groove width ranges from 1 to 10 cm with an error of less than 1%.

[0020] Another objective of this invention is to overcome the shortcomings of the prior art and provide an application of a pressure roller for explosion-proof carton lines in explosion-proof carton production lines. When the pressure roller is used in conjunction with the production line process, the carton explosion rate is reduced by 85-95%, and the carton quality rate is increased by 80-90% on the original basis.

[0021] Beneficial effects of this invention:

[0022] This invention addresses the problem of frequent bursting of packaging lines during current packaging production processes, proposing a practical solution that resolves the bursting problem in packaging carton production without adding extra processes or damaging the physical and chemical properties of the packaging carton.

[0023] This invention, when used in conjunction with a carton production line, does not increase additional costs, reduces the carton bursting rate by 85-95%, and increases the carton quality rate by 80-90%, thereby reducing production costs and improving the product quality rate.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] This invention provides a pressure roller for explosion-proof lines on cardboard boxes, see [link / reference]. Figure 1 , Figure 2 and Figure 3 This includes the main material of the pressure roller 100, the pressure line 200, and the groove strip 300; among which,

[0033] The main material 100 of the pressure roller includes a long side 101 and a short side 102;

[0034] The pressure line 200 includes pressure line 201 and pressure line 202. Pressure line 201 and pressure line 202 are fixedly arranged on the main material 100 of the pressure roller with equal length and parallel to each other, and are parallel to the long side 101.

[0035] The slot strip 300 is fixedly mounted on the long side 101.

Figure 4 It includes an automatic feeding machine 100, a printing, slotting, creasing and die-cutting system 200, a shaping system 300, an automatic packaging system 400, a conveying system 500 and a palletizing system 600;

[0037] Among them, the automatic feeder 100 flips the track cardboard and transports it into the printing press;

[0038] The printing, grooving, creasing and die-cutting system 200 is used to print graphics, cut dimensions and creasing and shaping on paperboard. In this invention, a pressure roller is added in the printing, grooving, creasing and die-cutting system 200 to cooperate with its creasing and shaping.

[0042] Example 1:

[0043] The plastic film material used for the pressure roller is made of high-viscosity PET with high temperature resistance and high performance that is not easily deformed, with a viscosity of 0.8 dl / g;

[0044] The pressure strip is made of silicone rubber with a hardness of 20 degrees and a tensile strength of 5MPa. It is bonded to the film material with sealant and then secured with fiber tape to prevent the pressure strip from falling off.

[0045] The crease width is 2cm, and the produced carton size is 0.5*1m. 2 ;

[0046] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 85%, and increasing the yield of acceptable products by 80%.

[0056] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 87%, and increasing the yield of acceptable products by 83%.

[0057] Increasing the viscosity at this point does not improve the effect, but it will increase the difficulty of film processing. Therefore, the optimal viscosity is 1.0 dl / g.

[0058] Example 4:

[0059] The plastic film material used for the pressure roller is made of high-viscosity PET with high temperature resistance and high performance that is not easily deformed, with a viscosity of 1.0 dl / g;

[0060] The pressure strip is made of silicone rubber with a hardness of 30 degrees and a tensile strength of 7MPa. It is bonded to the film material with sealant and then secured with fiber tape to prevent the pressure strip from falling off.

[0062] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 88%, and increasing the yield of acceptable products by 84%.

[0063] Example 5:

[0064] The plastic film material used for the pressure roller is made of high-viscosity PET with high temperature resistance and high performance that is not easily deformed, with a viscosity of 1.0 dl / g;

[0065] The pressure strip is made of silicone rubber with a hardness of 40 degrees and a tensile strength of 6MPa. It is bonded to the film material with sealant and then secured with fiber tape to prevent the pressure strip from falling off.

[0066] The crease width is 2cm, and the produced carton size is 0.5*1m. 2 ;

[0067] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 89%, and increasing the yield of acceptable products by 86%.

[0068] Example 6:

[0071] The crease width is 2cm, and the produced carton size is 0.5*1m. 2 ;

[0072] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 90%, and increasing the yield of acceptable products by 87%.

[0077] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 89%, and increasing the yield of acceptable products by 85%.

[0078] Increasing the rubber hardness at this point, however, results in excessive hardness, which fails to effectively buffer the pressure of the rollers passing through the pressure groove during carton manufacturing. This leads to a reduced reduction in the rate of cracking and a decrease in the rate of producing acceptable products. Therefore, a silicone rubber hardness of 50 degrees is optimal. Tensile strength varies with hardness, reflecting the material's performance characteristics.

[0091] The pressure strip is made of silicone rubber with a hardness of 50 degrees and a tensile strength of 7.5MPa. It is bonded to the film material with sealant and then secured with fiber tape to prevent the pressure strip from falling off. The groove width of the pressure strip is 2cm.

[0092] The production carton size is 0.5*1m. 2 ;

[0096] The pressure strip is made of silicone rubber with a hardness of 50 degrees and a tensile strength of 7.5MPa. It is bonded to the film material with sealant and then secured with fiber tape to prevent the pressure strip from falling off. The groove width of the pressure strip is 2cm.

[0097] The production carton size is 0.5*1m. 2 ;

[0098] The pressure roller works in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 95%, and increasing the yield of acceptable products by 90%.

[0099] Example 12:

[0100] The plastic film material used for the pressure roller is made of PET and PCT in a certain proportion, which are heat-resistant, high-performance and not easily deformed. The viscosity of PET is 1.0 dl / g and the melting point of PCT is 285℃. The mass ratio of the two added is PET:PCT = 1:1.

[0108] The pressure rollers work in conjunction with the carton production line, achieving a production speed of 8,000 pieces per hour, reducing the carton bursting rate by 93%, and increasing the yield of acceptable products by 89%.

[0109] Increasing the amount of PCT at this point does not actually reduce the rate of carton bursting or improve the yield of good products. This is mainly because PCT is a high-temperature resistant material. When the ratio of PCT to PET increases, it will affect the structure of PET as the main phase. At the same time, because PET has poor temperature resistance, the processing temperature will exceed 300°C when the PCT content increases, which will damage the performance of PET. Therefore, the film with the best performance is prepared when the optimal ratio of PET:PCT is 2:1.

[0110] Therefore, this invention addresses the problem of cardboard box bursting by designing a creasing roller that works in conjunction with a cardboard box production line. Through the design and combination of the creasing roller's raw materials, an online production technology that prevents cardboard box bursting is achieved, improving the yield rate of cardboard boxes, reducing production costs, and increasing enterprise efficiency.

[0111] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
