Description

Technical Field

[0001] This invention relates to the field of shoe packaging technology, specifically to a punching device for shoe boxes and its usage method. Background Technology

[0002] In the shoe production and processing process, shoe boxes are used to package the shoes to complete the entire production and processing process. In the process of selling shoes, in order to facilitate the retrieval of shoe boxes after they are stacked, holes need to be made on the side of the shoe boxes.

[0003] In the prior art, patent application CN106313623A discloses a punching device, particularly a quick punching device for shoe boxes used in shoe manufacturing. This device includes a support, a first slide rail, a first rack, a first connecting rod, a second slide rail, a second slider, a gear, a second rack, a second connecting rod, a placement plate, a second electric drill, a first spring, a second spring, a third slide rail, a third slider, a third electric drill, and a first push rod. The support has a first slide rail, a first connecting rod, and a second slide rail arranged sequentially from left to right at its top. While the aforementioned application increases the punching speed by using a fourth and third electric drill to punch holes in the shoe box on the L-shaped support rod, and by using the first and second electric drills to punch holes in the shoe box on the placement plate, during the punching process, the area around the punched shoe box is not fully fixed, leading to cracking around the punched hole. This results in poor aesthetics of the shoe box and hinders the punching process.

[0004] Therefore, a punching device for shoe boxes and its usage method are proposed. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a punching device for shoe boxes and its usage method, which solves the problem that the area around the cardboard box to be punched is not fully fixed, causing cracks to easily occur around the punched hole during the electric drill process.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] In this invention, a punching device for shoe boxes is provided for punching holes in cardboard. It includes a base and a placement mechanism mounted on the base. The placement mechanism includes a placement plate, which moves along a vertical direction via a first driving mechanism.

[0010] A support member is installed on the base, and a limiting mechanism is installed on the support member. The limiting mechanism includes a limiting block and a third driving mechanism. The limiting block moves along the vertical direction through the third driving mechanism, and the third driving mechanism is connected to the support member through a second connecting member.

[0011] The limiting block is located directly above the placement plate;

[0012] The limiting block has two second through holes, and the two second through holes communicate with the limiting block;

[0013] The base is provided with a pushing mechanism, which includes two first limiting plates and two second limiting plates. The two first limiting plates are arranged opposite each other, and the two second limiting plates are arranged opposite each other. Adjacent first limiting plates and second limiting plates are connected by a first connecting member.

[0014] The first limiting plate has a first through hole that corresponds one-to-one with the second through hole;

[0015] A second drive mechanism is mounted on the support member, and an electric drill is mounted on the end of the second drive mechanism away from the support member. The electric drill is used to drill holes, and the electric drill is at the same height as the first through hole.

[0016] Furthermore, in this invention, a glue storage tank is installed on the limiting block, and a second flow pipe is installed at each of the four corners of the limiting block. The glue storage tank is connected to the corresponding second flow pipe through the first flow pipe. A glue spraying head is provided on the second flow pipe, and a glue spraying hole corresponding to the glue spraying head is opened at each corner of the limiting block.

[0017] In this invention, the limiting block is further provided with an installation groove, the height of which is the same as the height of the second through hole. A pushing member is provided inside the installation groove. The pushing member is driven by a fourth driving mechanism. The pushing member is slidably connected to the limiting block through a sliding groove. The pushing member slides against the inner sidewall of the limiting block through a pushing assembly. The pushing assembly includes two pushing blades, which are located at the highest and lowest points of the second through hole, respectively.

[0018] Furthermore, in this invention, a stop is provided at the end of the pushing component away from the fourth driving mechanism, and the inner sidewalls of the stop and the limiting block are fitted together.

[0019] Furthermore, in this invention, each of the four corners of the limiting block is provided with a placement groove, and a reinforcing cardboard that is compatible with the placement groove is placed in the placement groove.

[0020] In this invention, the placement groove is further L-shaped.

[0021] Furthermore, in this invention, the reinforcing cardboard is provided with a flow groove corresponding to the glue spray hole.

[0022] In this invention, a cylinder is further installed at one end of the limiting block near the placement plate.

[0023] Furthermore, in this invention, the glue storage box is provided with a lid, and the lid is provided with a handle.

[0024] Furthermore, in this invention, a method for using a punching device for shoe boxes specifically includes the following steps:

[0025] S1: Cardboard board positioning. The third drive mechanism controls the positioning block to move upward, moving it away from the placement plate. The first drive mechanism is then controlled to raise the top of the placement plate to a position higher than the top of the first positioning plate. The cut cardboard board is then placed on the placement plate. The third drive mechanism controls the positioning block to fix the placed cardboard board.

[0026] S2: Folding of the cardboard board. The first and third driving mechanisms drive synchronously to control the fixed cardboard board to move downwards until the positions of the first and second through holes are at the same height. The placement plate stops moving. During the downward movement of the fixed cardboard board, the first and second limiting plates on the pushing mechanism push the cardboard board, thereby realizing that the cardboard board is wrapped around the outer surface of the limiting block. The cardboard board changes from a flat state after being cut to an open box shape. At this time, the inner side of the cardboard board contacts the outer wall of the limiting block, and the outer side of the cardboard board contacts the first and second limiting plates, thereby realizing the double-sided fixing and folding of the cardboard board.

[0027] S3: Symmetrical drilling. When the first through hole and the second through hole are at the same height, the second drive mechanism controls the electric drill to drill through the first through hole to drill the cardboard. Due to the setting of the two first through holes, symmetrical drilling is achieved on both sides of the cardboard.

[0028] S4: The fourth drive mechanism is activated to control the pusher to move along the direction of the slide groove toward the second through hole. At this time, the stop on the pusher first contacts the second through hole, blocking the center part of the second through hole. This prevents the circular paper from rotating into the hole when the pusher blade pushes the circular paper that has not yet left the hole. This would prevent the pusher blade from separating the circular paper from the cardboard. The pusher will push the circular paper that has been separated to the outside of the mounting groove, thus achieving a better punching effect.

[0029] S5: Reinforcement and bonding of cardboard: The reinforcing cardboard is placed inside the placement groove, and then the glue sprayed by the glue nozzle passes through the flow groove to complete the bonding of the reinforcing cardboard to the folded cardboard.

[0030] S6: Detachment of the cardboard sheet. After the cardboard sheet is glued on, wait for the glue to dry or be blown dry, then start the cylinder to push the cardboard sheet, which has been initially folded and is wrapped around the surface of the limiting block, to complete the detachment of the cardboard sheet.

[0031] (III) Beneficial Effects

[0032] This invention provides a punching device for shoe boxes and a method for using the same. Compared with the prior art, it has the following advantages:

[0033] 1. By using the placement mechanism, limiting mechanism and pushing mechanism in combination, the problem of hole breakage caused by the lack of simultaneous fixation on both sides of the cardboard when drilling holes with an electric drill is solved in the existing technology. This is not conducive to the aesthetics of shoe box drilling. At the same time, the shoe box is formed while achieving symmetrical drilling, thereby improving the production efficiency of shoe box manufacturing. Attached Figure Description

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] This application provides a punching device and method for shoe boxes, which solves the problem that the area around the punched cardboard box is not fully fixed, causing cracks to easily occur around the punched hole during the electric drill process, thus improving the punching effect of shoe boxes.

[0047] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0048] like Figures 1-8 As shown, a punching device for shoe boxes, used for punching cardboard 60, includes a base 10 and a placement mechanism mounted on the base 10. The placement mechanism includes a placement plate 20, which moves in a vertical direction via a first drive mechanism 21.

[0049] A support member 11 is installed on the base 10. A limiting mechanism is installed on the support member 11. The limiting mechanism includes a limiting block 50 and a third driving mechanism 52. The limiting block 50 moves in the vertical direction through the third driving mechanism 52. The third driving mechanism 52 is connected to the support member 11 through a second connecting member 521.

[0050] The limiting block 50 is located directly above the placement plate 20;

[0051] The limiting block 50 has two second through holes 502, and the two second through holes 502 communicate with the limiting block 50.

[0052] The base 10 is provided with a pushing mechanism, which includes two first limiting plates 31 and two second limiting plates 32. The two first limiting plates 31 are arranged opposite each other, and the two second limiting plates 32 are arranged opposite each other. Adjacent first limiting plates 31 and second limiting plates 32 are connected by a first connecting member 30.

[0053] The first limiting plate 31 has a first through hole 311 that corresponds one-to-one with the second through hole 502;

[0054] A second drive mechanism 40 is installed on the support member 11. An electric drill is installed at the end of the second drive mechanism 40 away from the support member 11. The electric drill is used to drill holes and is at the same height as the first through hole 311.

[0055] During operation, the two first through holes 311 and the two second through holes 502 are connected, and the electric drill passes through the first through holes 311 and the second through holes 502 to complete the drilling operation.

[0056] When punching holes in the shoe box, firstly, the third drive mechanism 52 controls the limiting block 50 to move upward, moving the limiting block 50 away from the placement plate 20. Then, the first drive mechanism 21 controls the top of the placement plate 20 to rise above the top of the first limiting plate 31, so that the cut cardboard board 60 can be placed on the placement plate 20. The third drive mechanism 52 controls the limiting block 50 to fix the placed cardboard board 60.

[0057] Then, the first drive mechanism 21 and the third drive mechanism 52 drive synchronously to control the fixed cardboard board 60 to move downwards until the positions of the first through hole 311 and the second through hole 502 are at the same height. The placement plate 20 stops moving. During the downward movement of the fixed cardboard board 60, the first limiting plate 31 and the second limiting plate 32 on the pushing mechanism push the cardboard board 60, thereby realizing that the cardboard board 60 wraps around the outer surface of the limiting block 50. The cardboard board 60 changes from a flat state after being cut to an open box shape. At this time, the inner side of the cardboard board 60 contacts the outer wall of the limiting block 50, and the outer side of the cardboard board 60 contacts the first limiting plate 31 and the second limiting plate 32, thereby realizing the double-sided fixation of the cardboard board 60, improving the stability of the cardboard board 60 after fixation, and enabling the cardboard board 60 to be folded into a box shape, which is convenient for the subsequent shoe box production and improves the processing efficiency of the shoe box.

[0058] When the first through hole 311 and the second through hole 502 are at the same height, the second drive mechanism 40 controls the electric drill to pass through the first through hole 311 and drill holes in the cardboard board 60. Due to the setting of the two first through holes 311, symmetrical drilling is achieved on both sides of the cardboard board 60. At the same time, the cardboard board 60 is fixed by the limiting block 50, the first limiting plate 31 and the second limiting plate 32, which solves the problem in the prior art that when the electric drill drills holes in the cardboard board 60, the holes are not fixed on both sides at the same time, resulting in hole breakage, which is not conducive to the aesthetics of the shoe box. At the same time, the shoe box is formed when symmetrical drilling is achieved, thereby improving the production efficiency of shoe box manufacturing.

[0059] The limiting block 50 is equipped with a glue storage tank 51. Each of the four corners of the limiting block 50 is equipped with a second flow pipe 512. The glue storage tank 51 is connected to the corresponding second flow pipe 512 through the first flow pipe 511. The second flow pipe 512 is equipped with a glue spraying head. The corners of the limiting block 50 are provided with glue spraying holes that correspond one-to-one with the glue spraying heads.

[0060] The glue storage box 51 is equipped with a lid and a handle, which facilitates the subsequent addition of glue to the glue storage box 51.

[0061] During operation, after the cardboard is folded 60° into a box, the glue spray head sprays glue through the glue spraying hole into the gap of the fold, thus achieving the glue spraying closure operation around the box.

[0062] like Figure 4 and Figure 5 As shown, the limiting block 50 has an installation groove 501, the height of which is the same as the height of the second through hole 502. A pusher is provided inside the installation groove 501. The pusher is driven by the fourth drive mechanism 53. The pusher is slidably connected to the limiting block 50 through a sliding groove 533. The pusher slides against the inner wall of the limiting block 50 through a pusher assembly. The pusher assembly includes two pusher blades 531. The two pusher blades 531 located on the same pusher assembly are located at the highest point and the lowest point of the second through hole 502, respectively. A stop block 532 is provided at the end of the pusher assembly away from the fourth drive mechanism 53. The stop block 532 is fitted against the inner wall of the limiting block 50.

[0063] During operation, after the electric drill drills two symmetrical holes in the cardboard plate 60 through the first through hole 311 and the second through hole 502, the electric drill retracts from the limiting block 50 and the first limiting plate 31 under the action of the second drive mechanism 40. At this time, the circular paper piece produced by the electric drill may exist in the hole in the mounting groove 501 near the second drive mechanism 40, resulting in the circular paper piece not being completely detached. If the cardboard plate 60 is directly detached from the limiting block 50 in the future, it may cause tearing between the circular paper piece and the hole. Therefore, a pushing component is set up to solve the above-mentioned problem.

[0064] When using the pusher, the fourth drive mechanism 53 is activated to control the pusher to move along the direction of the slide groove 533 toward the second through hole 502. At this time, the stop block 532 on the pusher first contacts the second through hole 502, blocking the center part of the second through hole 502. This prevents the circular paper from rotating into the hole when the pusher blade 531 pushes the circular paper that has not yet left the hole, causing the pusher blade 531 to fail to separate the circular paper from the paperboard 60. The pusher will push the circular paper that has been separated to the outside of the mounting groove 501, thus better completing the punching effect.

[0065] like Figures 6-7 As shown, further, each of the four corners of the limiting block 50 is provided with a placement groove 503. The placement groove 503 is L-shaped. A reinforcing cardboard 61 that is compatible with the placement groove 503 is placed in the placement groove 503. A flow groove 611 corresponding to the glue spray hole is provided on the reinforcing cardboard 61.

[0066] During operation, after the cardboard 60 is folded into a box shape, the reinforcing cardboard 61 is placed inside the placement groove 503 to stabilize the joint gap after the cardboard 60 is folded. Then, the glue sprayed by the glue spray head passes through the flow groove 611 to complete the bonding between the reinforcing cardboard 61 and the folded cardboard 60, thereby improving the stability of the shoe box bonding.

[0067] like Figure 8 As shown, a cylinder 54 is installed at one end of the limiting block 50 near the placement plate 20.

[0068] During operation, after the cardboard 60 is glued, once the glue is dry or blown dry, the cylinder 54 is activated to push the cardboard 60, which is initially folded and wrapped around the surface of the limiting block 50, so that the cardboard 60 can be detached after folding, thus allowing the shoe box to be processed in the next step.

[0069] A method for using a punching device for shoe boxes includes the following steps:

[0070] S1: The cardboard board 60 is positioned. The third drive mechanism 52 controls the limiting block 50 to move upward, and the limiting block 50 moves away from the placement plate 20. The first drive mechanism 21 is controlled to raise the top of the placement plate 20 to a position higher than the top of the first limiting plate 31. The cut cardboard board 60 is placed on the placement plate 20. The third drive mechanism 52 controls the limiting block 50 to fix the placed cardboard board 60.

[0071] S2: Folding of the cardboard 60: The first drive mechanism 21 and the third drive mechanism 52 drive synchronously to control the fixed cardboard 60 to move downward until the positions of the first through hole 311 and the second through hole 502 are at the same height. The placement plate 20 stops moving. During the downward movement of the fixed cardboard 60, the first limiting plate 31 and the second limiting plate 32 on the pushing mechanism push the cardboard 60, thereby realizing that the cardboard 60 is wrapped around the outer surface of the limiting block 50. The cardboard 60 changes from a flat state after being cut to an open box shape. At this time, the inner side of the cardboard 60 contacts the outer wall of the limiting block 50, and the outer side of the cardboard 60 contacts the first limiting plate 31 and the second limiting plate 32, thereby realizing the double-sided fixing and folding of the cardboard 60.

[0072] S3: Symmetrical drilling. When the positions of the first through hole 311 and the second through hole 502 are at the same height, the second drive mechanism 40 controls the electric drill to drill through the first through hole 311 to drill the paperboard 60. Due to the setting of the two first through holes 311, symmetrical drilling is achieved on both sides of the paperboard 60.

[0073] S4: The fourth drive mechanism 53 is activated to control the pusher to move along the slide groove 533 toward the second through hole 502. At this time, the stop block 532 on the pusher first contacts the second through hole 502, blocking the center part of the second through hole 502. This prevents the circular paper from rotating into the hole when the pusher blade 531 pushes the circular paper that has not yet left the hole. This would prevent the pusher blade 531 from achieving the effect of separating the circular paper from the paperboard 60. The pusher will push the circular paper that has been separated to the outside of the mounting groove 501, thus better completing the punching effect.

[0074] S5: Reinforcing and bonding of cardboard 60: Reinforcing cardboard 61 is placed inside placement groove 503, and then the glue sprayed by the glue spray head passes through flow groove 611 to complete the bonding of reinforcing cardboard 61 to folded cardboard 60.

[0075] S6: Detachment of the cardboard 60. After the cardboard 60 is glued, wait for the glue to dry or the glue to be blown dry, then start the cylinder 54 to push the cardboard 60, which is initially folded and wrapped around the surface of the limiting block 50, to complete the detachment of the cardboard 60.

[0076] In summary, compared with existing technologies, it has the following beneficial effects:

[0077] 1. By using the placement mechanism, limiting mechanism, and pushing mechanism in combination, the cardboard board 60 is fixed on both sides, improving its stability after fixing. It also allows the cardboard board 60 to be folded into a box shape, facilitating subsequent shoebox production and improving processing efficiency. This solves the problem in existing technologies where, when drilling holes in the cardboard board 60, the holes are not simultaneously fixed on both sides, leading to hole breakage and affecting the aesthetics of the shoebox. Furthermore, symmetrical drilling of the shoebox facilitates its shaping, thereby improving production efficiency.

[0078] 2. By setting up a pusher, the stop 532 on the pusher first contacts the second through hole 502, blocking the center part of the second through hole 502. This prevents the circular paper from rotating into the hole when the pusher blade 531 pushes the circular paper that has not yet detached from the hole, causing the pusher blade 531 to fail to separate the circular paper from the paperboard 60. This solves the problem in the prior art where directly detaching the paperboard 60 may cause tearing between the circular paper and the hole.

[0079] 3. After the cardboard 60 is folded into a box shape by reinforcing the cardboard 61 and spraying glue, the reinforcing cardboard 61 is placed inside the placement groove 503 to stabilize the joint gap after the cardboard 60 is folded. Then, the glue sprayed by the glue spray head completes the bonding between the reinforcing cardboard 61 and the folded cardboard 60 through the flow groove 611, thereby improving the stability of the shoe box bonding.

During the downward movement of the fixed cardboard (60), the first limiting plate (31) and the second limiting plate (32) on the pushing mechanism push the cardboard (60) to achieve the cardboard (60) wrapped around the outer surface of the limiting block (50). The cardboard (60) changes from a flat state after cutting to an open box shape. At this time, the inner side of the cardboard (60) contacts the outer wall of the limiting block (50), and the outer side of the cardboard (60) contacts the first limiting plate (31) and the second limiting plate (32), thereby achieving the double-sided fixing and folding of the cardboard (60). S3: Symmetrical drilling. When the first through hole (311) and the second through hole (502) are at the same height, the second drive mechanism (40) controls the electric drill to drill through the first through hole (311) to the paperboard (60). Due to the setting of the two first through holes (311), symmetrical drilling is achieved on both sides of the paperboard (60). S4: Start the fourth drive mechanism (53) to control the pusher to move along the direction of the slide (533) toward the second through hole (502). At this time, the stop (532) on the pusher will first contact the second through hole (502) and block the center part of the second through hole (502) to prevent the circular paper from rotating into the hole when the pusher blade (531) pushes the circular paper that has not yet left the hole. This would prevent the pusher blade (531) from achieving the effect of separating the circular paper from the paperboard (60). The pusher will push the circular paper that has been separated to the outside of the mounting groove (501) to better complete the punching effect. S5: Reinforcement and bonding of cardboard (60): The reinforcing cardboard (61) is placed inside the placement groove (503), and then the glue sprayed by the glue spray head passes through the flow groove (611) to complete the bonding of the reinforcing cardboard (61) to the folded cardboard (60). S6: Detachment of the paperboard (60): After the paperboard (60) is glued, wait until the glue dries or the glue is blown dry, start the cylinder (54) to push the paperboard (60) wrapped on the surface of the limiting block (50) after the initial folding and shaping, and complete the detachment of the paperboard (60).
