Description

Technical Field

[0001] This invention relates to the field of packaging box processing technology, specifically to a paper-attached wall forming process for paper boxes. Background Technology

[0002] In the production process of barrel-shaped packaging boxes, in order to more securely fix the barrel body and the lid together, connecting paper is used to connect the barrel body and the lid together, and then side paper is used to glue the sides and bottom of the barrel body.

[0003] The current bonding process for side paper is inadequate, making it impossible to guarantee precise bonding. Furthermore, manual assistance is required during the bonding process, resulting in slow bonding efficiency and hindering the progress of the side paper bonding procedure. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a paper-attached wall forming process for the side of a paper box.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a paper-wall forming process for the side of a paper box, comprising the following steps:

[0006] S1. After applying glue to the side paper, the side paper is conveyed to the pasting station. The side paper is used to bond to the bottom of the cardboard box and the two sides opposite to the bottom.

[0007] S2. The cardboard box is adsorbed by the transfer mechanism, and a four-station turntable is set up to drive the transfer mechanism to move and transfer the cardboard box to the top of the side paper.

[0008] S3. Press down on the cardboard box so that the bottom of the cardboard box is glued to the side paper;

[0009] S4. Brush the two ends of the side paper until the side paper is attached to the two side walls of the box.

[0010] S5. Press the bubble on the cardboard box with the side paper attached to ensure that the side paper is firmly attached to the cardboard box.

[0011] Furthermore, in step S4, before brushing the side paper, the paper box is positioned to ensure its stable position during the brushing process.

[0012] Furthermore, during the brushing process of the side paper, the side paper is guided and supported to ensure that it is neatly adhered to the cardboard box.

[0013] Furthermore, after step S4, the two ends of the side paper are higher than the two side walls of the paper box. The side paper that is higher than the two side walls of the paper box is folded so that the two ends of the side paper are glued to the inside of the two side walls of the paper box.

[0014] Furthermore, the steps for folding the side paper include:

[0015] S1.1, Move the folding plate used for folding upwards;

[0016] S1.2, Press the bubble in the cardboard box to achieve positioning of the cardboard box;

[0017] S1.3 The folding plate moves forward and pushes the side paper that is higher than the two side walls of the cardboard box inward.

[0018] S1.4 The folding plate moves down, causing the side paper, which has been pushed inward, to move down, so that the side paper is adhered to the inside of the two side walls of the paper box.

[0019] Furthermore, after folding the side paper, the transfer mechanism is released from transferring the cardboard box, separating the transfer mechanism from the cardboard box.

[0020] Furthermore, after separating the transfer mechanism from the cardboard box, the cardboard box is pushed to send it to the next process.

[0021] Furthermore, prior to S2, a conveying mechanism is set up to convey the paper box, and a positioning mechanism for positioning the paper box is set on the conveying mechanism; the transfer mechanism, driven by the four-station turntable, transfers the paper box positioned by the positioning mechanism to the top of the side paper.

[0022] Compared with the prior art, the present invention has the following beneficial effects: The molding process provided by the present invention ensures accurate bonding between the bottom of the barrel body and the side paper by transferring the barrel body of the barrel-shaped paper box to the top of the side paper. Furthermore, by brushing the two ends of the side paper, it can ensure that the two ends of the side paper are accurately bonded to the barrel body, thereby improving the accuracy of bonding the side paper to the barrel-shaped paper box. No manual assistance is required, ensuring the automation of side paper bonding and improving the efficiency of side paper bonding. Attached Figure Description

[0040] Example 1:

[0041] like Figure 1-9 As shown, the paper-wall forming process for the side of the paper box of the present invention includes the following steps:

[0042] S1. After applying glue to the side paper, the side paper is conveyed to the pasting station. The side paper is used to bond to the bottom surface of the cardboard box and the two sides opposite to the bottom surface. Conveyor belt 2 is set up to convey the glued side paper.

[0043] S2. A conveying mechanism 4 is set to convey the paper box, and a positioning mechanism 41 for positioning the paper box is set on the conveying mechanism 4; the transfer mechanism 1 adsorbs the paper box and transfers the paper box positioned by the positioning mechanism 41 under the drive of the four-station turntable 9, and transfers the paper box to the top of the side paper.

[0044] S3. Press down on the cardboard box so that the bottom of the cardboard box is glued to the side paper;

[0045] S4. Position the cardboard box to ensure its stability during the brushing process on the side paper. Brush both ends of the side paper until it adheres to the two side walls of the cardboard box. During the brushing process, guide and support the side paper to ensure it adheres neatly to the cardboard box.

[0046] S5. Press the bubble on the cardboard box with the side paper attached to ensure that the side paper is firmly attached to the cardboard box.

[0047] Preferably, the design includes an upper brushing mechanism 3 for brushing the side paper. The upper brushing mechanism 3 includes spaced-apart support plates 31 disposed at the rear end of the conveying mechanism 4 in the traveling direction, upper brush rollers 33 spaced-apart between the support plates 31, and a first power component 34 for driving the upper brush rollers 33 to move up and down. The upper brush rollers 33 brush both sides of the side paper. A connecting plate 341 is provided at the output end of the first power component 34, and the upper brush rollers 33 are rotatably mounted on the connecting plate 341. This design, by providing upper brush rollers 33 on both sides of the barrel mold 11, facilitates the upward movement of the upper brush rollers 33 driven by the first power component 34. During the upward movement of the upper brush rollers 33, both sides of the side paper are brushed, thereby adhering the sides of the side paper to the side walls of the cardboard box, thus achieving the adhesion of the side paper.

[0048] Preferably, the support plate 31 is provided with a positioning plate 351 for positioning the cardboard box and a second power component 352 for driving the positioning plate 351 to move back and forth. This design facilitates the positioning of the cardboard box by the positioning plate 351 when the body mold 11 transfers the cardboard box onto the side paper, thereby ensuring that both sides of the cardboard box are attached to the body mold 11 and preventing the position of the cardboard box from changing during the brushing process on the side paper.

[0049] Preferably, the support plate 31 is provided with a limiting mechanism 32 for limiting the two sides of the side paper. The limiting mechanism 32 includes a limiting plate 321 for limiting the two side edges of the side paper and a third power member 322 for adjusting the position of the limiting plate 321. This design, by setting the limiting plate 321, facilitates adjustment according to the size of the side paper, thereby limiting the side paper and facilitating alignment between the side paper and the transfer mechanism 1.

[0050] Preferably, the positioning plate 351 is provided with an edge-supporting block 36 for supporting the side paper during the brushing process of the upper brush roller 33. With this design, during the brushing process of the upper brush roller 33, the edge-supporting block 36 can support both sides of the side paper, so that the side paper will not shift and can be accurately adhered to the paper box.

[0051] Preferably, the positioning mechanism 41 includes a guide plate 42 disposed at the rear end of the conveyor belt 2 in the traveling direction, and the guide plate 42 is provided with a positioning block 43 for positioning the cardboard box. This design facilitates the conveying mechanism 4 by transporting the cardboard box onto the guide plate 42, and the positioning block 43 positions the guide plate 42, thereby facilitating the transfer mechanism 1 to adsorb and transfer the cardboard box.

[0052] Preferably, the transfer mechanism 1 includes a barrel mold 11 for adsorbing the barrel body, and the bottom of the barrel mold 11 is provided with a suction cup 111 for adsorbing the bottom of the barrel body. The suction cup 111 is externally connected to an air pump. This design facilitates the adsorption and transfer of the barrel body by the transfer mechanism 1, thereby facilitating the bonding of the side paper.

[0053] It should be noted that after step S4, the two ends of the side paper are higher than the two side walls of the cardboard box. The side paper that is higher than the two side walls of the cardboard box is folded over so that the two ends of the side paper are adhered to the inside of the two side walls of the cardboard box. The step of folding the side paper includes:

[0054] S1.1 Move the folding plate 63 used for folding upwards;

[0055] S1.2, Press the bubble in the cardboard box to achieve positioning of the cardboard box;

[0056] S1.3, the folding plate 63 moves forward and pushes the side paper that is higher than the two side walls of the cardboard box inward;

[0057] S1.4 The folding plate 63 moves down, causing the side paper that has been pushed inward to move down, so that the side paper is adhered to the inside of the two side walls of the paper box.

[0058] S1.5 After folding the side paper, release the transfer mechanism from the paper box and separate the transfer mechanism from the paper box; after separating the transfer mechanism from the paper box, push the paper box to send it to the next process.

[0059] Preferably, it further includes a bubble pressing mechanism 5 for pressing the bubble in the cardboard box after the side paper is glued, and a folding mechanism 6 for folding the side paper higher than the side walls of the cardboard box inward. The bubble pressing mechanism 5 includes a placement plate 51 for placing the cardboard box and bubble pressing plates 52 disposed on both sides of the placement plate 51. A ninth power member 64 is disposed at the bottom of the placement plate 51. A fourth power member 53 is disposed on the outside of the bubble pressing plate 52 for driving the bubble pressing plate 52 to move horizontally. The folding mechanism 6 includes a fifth power member 61 disposed on the bubble pressing plate 52 and a horizontal plate 62 disposed on the fifth power member 61. A downwardly protruding folding plate 63 is disposed on the horizontal plate 62. This design allows for the following operations: When it's necessary to compress the bubble wrap on the cardboard box after the side paper is glued and to fold the side paper that extends above the side walls of the cardboard box inwards; firstly, the fifth power component 61 moves the horizontal plate 62 and the folding plate 63 upwards, and the transfer mechanism 1 moves the cardboard box onto the placement plate 51. Then, the fourth power component 53 moves the bubble-compressing plates 52 on both sides closer to the fifth power component 61, causing the bubble-compressing plates 52 to compress the bubble wrap on the side paper and the cardboard box. Simultaneously, the folding plate 63, under the action of the fourth power component 53, folds the side paper that extends above the side walls of the cardboard box inwards. Then, the fifth power component 61 moves the horizontal plate 62 and the folding plate 63 downwards, and during the downward movement of the folding plate 63, it folds the inwardly folded side paper downwards. The pressure causes the side paper, which is higher than the side walls of the cardboard box, to adhere to the inner side wall of the cardboard box. The fifth power component 61 drives the horizontal plate 62 and the folding plate 63 to move upward, and the fourth power component 53 drives the bubble pressing plate 52 to reset. Then, the fifth power component 61 drives the horizontal plate 62 and the folding plate 63 to reset, realizing the bubble pressing of the cardboard box after the side paper is adhered and the inward folding of the side paper that is higher than the side walls of the cardboard box. By setting the ninth power component 64, it is easy to adjust the height of the placement plate 51, so that the folding plate 63 can be pressed down. This avoids the folding plate 63 being unable to press down the excess side paper due to the size of the cardboard box, thus ensuring that the side paper can be completely adhered to the inner side walls of the cardboard box.

[0060] Preferably, the four-station turntable 9 includes a central rotating shaft 91 and moving modules 92 arranged around the central rotating shaft 91 to drive the transfer mechanism 1 to move in four stations. The four-station turntable 9 is used to drive the transfer mechanism 1 to clamp the paper box conveyed on the conveyor belt 2, transfer the paper box to the brushing mechanism 3 to stick the side paper, and then transfer it to the bubble pressing mechanism 5 to press the bubble and fold the side paper higher than the two side walls of the paper box inward. Finally, the paper box is transferred to the demolding mechanism 7 for demolding, and then the paper box is pushed out by the ejection mechanism 8.

[0061] Preferably, in step S1.5, a demolding mechanism 7 separates the mold from the cardboard box, and an ejection mechanism 8 ejects the demolded cardboard box. The demolding mechanism 7 includes demolding templates 71 on both sides of the conveyor plate and a sixth power component 72 for moving the two demolding templates 71 closer together or further apart. A hook plate 73 is provided on the top of each demolding template 71 for detaching the cardboard box from the transfer mechanism 1. The ejection mechanism 8 includes a seventh power component 81 and a push plate 82 for pushing the detached cardboard box. With this design, when the cardboard box is transferred to the demolding mechanism 7 via the transfer mechanism 1, the sixth power component 72 drives the demolding templates 71 to adhere to the cardboard box. The transfer mechanism 1 moves upward, and under the action of the hook plate 73, the cardboard box detaches from the transfer mechanism 1. Then, driven by the sixth power component 72, the demolding templates 71 on both sides move further apart, and the seventh power component 81 drives the push plate 82 to push the cardboard box out and send it to the next process.

[0062] Example 2:

[0063] like Figure 10 As shown, the difference between this embodiment and Embodiment 1 is only that the transfer mechanism 1 includes a barrel body mold 11 and a barrel lid mold 12 for adsorbing the barrel body and lid in the open state. The bottom of the barrel body mold 11 and the barrel lid mold 12 are respectively provided with suction cups 111 for external air pumps. This design, by setting the barrel body mold 11 and the barrel lid mold 12, facilitates the adsorption and transfer of cardboard boxes with barrel bodies and lids in the open state.

[0064] Example 3:

[0065] like Figure 11-12 As shown, the difference between this embodiment and Embodiment 1 lies only in that the transfer mechanism 1 includes a barrel mold 11 for adsorbing the barrel body and an adsorption mechanism 13 disposed on the barrel mold 11 for adsorbing the barrel lid, causing the barrel lid to tilt. The adsorption mechanism 13 includes an adsorption plate 131 disposed on the moving module 92. The adsorption plate 131 is rotatably disposed on the moving module 92 via a rotating rod. The moving module 92 is provided with an eighth power component 132 for adjusting the tilt angle of the adsorption plate 131. This design facilitates the positioning of the barrel lid, thereby avoiding obstruction of the barrel lid during the side paper bonding process.

[0066] Preferably, the first power component 34, the second power component 352, the third power component 322, the fourth power component 53, the fifth power component 61, the moving module 92, the sixth power component 72, the seventh power component 81, the eighth power component 132 and the ninth power component 64 include, but are not limited to, linear guides, linear modules, cylinders, hydraulic cylinders, electric push rods and lead screws.

[0067] Preferably, the conveyor belt 2 and the conveying mechanism 4 are commonly used conveyor belt structures in the prior art, so the specific structure will not be described in detail here.

[0068] Preferably, the conveying mechanism 4 is provided with a guide mechanism 44 for supporting and guiding the bucket lid, and the guide mechanism 44 includes a guide rod 441 disposed on the conveying mechanism 4.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
