Description
Technical Field
[0001] This application relates to the field of drawer box and leather case manufacturing technology, and more particularly to an apparatus for manufacturing drawer boxes and leather cases. Background Technology
[0002] In the process of forming or processing cardboard boxes, it is necessary to laminate the face paper to the cardboard. The face paper is stacked on a lifting platform and raised, where a feeding device (such as a feeder) feeds each sheet of face paper from the top layer into a gluing machine (including gluing rollers) for gluing. After gluing, the face paper is output from the gluing machine and conveyed to a positioning machine. The positioning machine then positions and laminates the cardboard to the face paper on the conveyor belt (forming the material). The laminated material is then output for other operations (e.g., forming the body of a cardboard box). This material can be used for processing and manufacturing cardboard boxes (especially long cardboard boxes), wine boxes, framed boxes, book boxes, drawer boxes, etc. However, existing equipment can only produce one type of box. For example, a separate cardboard box manufacturing machine must be purchased for cardboard boxes, and a separate drawer box manufacturing machine is required for drawer boxes, resulting in extremely high production costs. This application addresses this problem by inventing an integrated device for producing drawer boxes and cardboard boxes. Summary of the Invention
[0003] In view of this, the present application aims to provide an apparatus for manufacturing drawer boxes and leather cases, in order to solve some or all of the aforementioned technical problems.
[0004] To achieve the above objectives, this application provides an apparatus for manufacturing drawer boxes and leather cases, comprising:
[0005] The first conveying mechanism includes a conveyor belt for feeding the material to be folded;
[0006] The first folding mechanism includes a long-side folding mechanism and a short-side folding mechanism for folding at least one side of the material to be folded. The folding direction of the long-side folding mechanism is perpendicular to the folding direction of the short-side folding mechanism. When the long-side folding mechanism and the short-side folding mechanism operate synchronously, the four sides of the material to be folded are folded to generate a shell. When either the long-side folding mechanism or the short-side folding mechanism is operating, at least one side of the material to be folded is folded to generate a partially folded material.
[0007] The second folding mechanism includes a drawer box forming station, a drawer box mold station, and a drawer box folding assembly. The drawer box forming station, under the action of the drawer box mold, shapes a portion of the folding material so that the folded material falls into the drawer box folding assembly for folding to generate a drawer box.
[0008] Optionally, the device further includes an adsorption mechanism, which includes a movable adsorption cylinder positioned directly above the first folding mechanism and the second folding mechanism.
[0009] Optionally, the long-side folding mechanism includes: two symmetrically arranged first movable frames, two long-side folding plates, two first placement plates, and two sets of long-side driving components. The two first placement plates are respectively disposed on the corresponding first movable frames, the two long-side folding plates are respectively disposed on the corresponding first movable frames, the two first placement plates are located between the two long-side folding plates, and the two sets of long-side driving components are respectively disposed on the corresponding first movable frames and drive the corresponding long-side folding plates to fold.
[0010] Optionally, the long side folding mechanism further includes a long side distance adjustment component for adjusting the movement of the long side folding plate. The long side distance adjustment component includes a first distance main adjustment component and a first distance secondary adjustment component. The first distance main adjustment component is disposed at one end of the first moving frame, and the first distance secondary adjustment component is disposed at the end of the first moving frame away from the first distance main adjustment component.
[0011] Optionally, the first distance main adjustment component includes a long side distance adjustment motor, a first gear, and a first rack. The rack is mounted on the frame, the first gear is rotatably mounted on the first movable frame, and one end of the first gear is provided with a first grooved wheel, which is connected to the long side distance adjustment motor.
[0012] The first distance adjustment component includes a second gear and a second rack. The second rack is symmetrically arranged with the first rack and is mounted on the frame. The second gear is symmetrically arranged with the first gear at the end of the first moving frame away from the first gear. The first gear and the second gear are connected by a rotating shaft.
[0013] Optionally, the long side folding mechanism also includes an ear-cutting mechanism, which includes four ear-cutting cylinders arranged in a four-corner array, and the four ear-cutting cylinders are distributed on two symmetrically arranged long side folding plates.
[0014] Optionally, the short-side folding mechanism includes: two symmetrically arranged second movable frames, two short-side folding plates, two second placement plates, and two sets of short-side driving components. The two second placement plates are respectively disposed on their corresponding second movable frames, the two short-side folding plates are respectively disposed on their corresponding second movable frames, the two second placement plates are located between the two short-side folding plates, and the two sets of short-side driving components are respectively disposed on their corresponding second movable frames and drive the corresponding short-side folding plates to fold.
[0015] Optionally, the drawer box mold station includes a movable moving component and a drawer box mold disposed on the moving component. The drawer box forming station includes two symmetrically arranged forming plates. A forming space is provided between the two forming plates for the drawer box mold to pass through. Symmetrically arranged baffles are provided in the forming space. Drawer box material is disposed on the forming plates. Under the action of the moving component, the drawer box mold presses the drawer box material through the forming space, so that the drawer box material enters between the two baffles and partially wraps around the drawer box mold. The drawer box mold and the drawer box material fall into the drawer box folding component.
[0016] Optionally, the drawer box folding station includes a drawer box gray board bending plate, a drawer box side folding push plate, a drawer box first bottom folding push plate, a drawer box second bottom folding push plate, a drawer box third bottom folding push plate, and a drawer box folding drive assembly corresponding to each push plate. The drawer box gray board bending push plate is symmetrically arranged with the drawer box side folding push plate, and the drawer box first bottom folding push plate is symmetrically arranged with the drawer box second bottom folding push plate. The drawer box first bottom folding push plate is adjacent to the drawer box gray board bending push plate and the angle between them is 90°. The drawer box second bottom folding push plate is adjacent to the drawer box side folding push plate and the angle between them is 90°. The drawer box third bottom folding push plate is located on the same plane and perpendicular to the drawer box first bottom folding push plate and the drawer box second bottom folding push plate.
[0017] Optionally, the first conveying mechanism further includes a straightening cylinder, which is disposed in the conveyor belt in the feeding direction.
[0018] As can be seen from the above, the device provided in this application for manufacturing drawer boxes and leather cases achieves integrated structural adaptation of leather case and drawer box manufacturing. Through the structural design of vertical folding of the long and short side folding mechanisms in the first folding mechanism, and the action logic of "synchronous operation to manufacture leather cases and single mechanism operation to manufacture part of the folding material", combined with the progressive structural layout of the drawer box forming, mold matching, and folding components of the second folding mechanism, the same set of equipment can complete the manufacturing process of two products through the operation combination of different mechanisms. This breaks through the structural limitations of traditional single-product manufacturing equipment, realizes the integration of the core functions of the equipment, and avoids the redundancy of purchasing multiple equipment from a structural perspective. Achieving a continuous and automated flow structure between processes, the first conveying mechanism provides a stable material conveying foundation for the subsequent folding process, and the folding output of the first folding mechanism can be directly used as the processing raw material for the second folding mechanism. The mechanisms form a continuous process structure of "conveyance-folding-forming-re-folding", without the need for additional transfer structure connections, realizing a closed loop in the material processing flow, allowing the production of leather shells and drawer boxes to be completed continuously within the equipment, thus improving the efficiency of process flow. The structure achieves structural adaptability and flexibility in the folding and forming processes. The vertical structural design of the long and short side folding mechanisms ensures precise structural matching of the four sides of the shell during folding. The second folding mechanism integrates the forming station, mold station, and folding component into a single layout. The structural cooperation between the mold station and the forming station enables precise forming of some folding materials. The formed material can be directly dropped into the folding component to complete the final folding. The structures of each station are mutually adaptable and their actions are connected. At the same time, the production process of the shell / drawer box can be flexibly switched through different operating modes of the first folding mechanism, allowing the equipment structure to adapt to the different processing requirements of the two products, realizing the adaptability of a single equipment structure to diversified production.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.
[0030] It should be noted that, unless otherwise defined, the technical or scientific terms used in the embodiments of this application should have the ordinary meaning understood by one of ordinary skill in the art to which this application pertains. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.
[0031] Through specific embodiments and in combination Figures 1-7 The technical solution of this application will be described in detail below.
[0032] In view of this, such as Figures 1-7 As shown, an apparatus for manufacturing drawer boxes and leather cases includes:
[0033] The first conveying mechanism 1 includes a conveyor belt for feeding the material to be folded;
[0034] The first folding mechanism 2 includes a long-side folding mechanism 21 and a short-side folding mechanism 22 for folding at least one side of the material to be folded. The folding direction of the long-side folding mechanism 21 is perpendicular to the folding direction of the short-side folding mechanism 22. When the long-side folding mechanism 21 and the short-side folding mechanism 22 operate synchronously, the four sides of the material to be folded are folded to generate a shell. When either the long-side folding mechanism 21 or the short-side folding mechanism 22 is operating, at least one side of the material to be folded is folded to generate a partially folded material.
[0035] The second folding mechanism 3 includes a drawer box forming station 31, a drawer box mold 323 station, and a drawer box folding assembly 33. The drawer box forming station 31, under the action of the drawer box mold, forms part of the folding material so that the formed material to be folded falls into the drawer box folding assembly 33 for folding to generate a drawer box.
[0036] In some embodiments, such as Figure 1 , Figure 2 As shown, the first conveying mechanism 1 further includes a straightening cylinder, which is disposed in the conveyor belt in the feeding direction.
[0037] Specifically, one end of the conveyor belt is connected to a device for pasting gray board and face paper. This can be existing equipment, and its specific structure will not be described in detail here. A straightening cylinder is used to straighten the material to be folded conveyed by the conveyor belt to a preset position. After the material is straightened, it is easier for the next station to align it and accurately perform the next operation. Straightening means moving the material to be folded from its preset position to the preset position.
[0038] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device also includes an adsorption mechanism 4, which includes a movable adsorption cylinder, and the adsorption cylinder is positioned directly above the first folding mechanism 2 and the second folding mechanism 3.
[0039] Specifically, the first conveying mechanism 1, the first folding mechanism 2, and the second folding mechanism 3 are all located inside the frame, while the adsorption mechanism 4 is located on the top of the frame. The adsorption cylinders may include a first adsorption cylinder 41 and a second adsorption cylinder 42. The two adsorption cylinders are each controlled by a translation mechanism, which employs a slide rail and slider cooperation structure, which will not be described in detail here. The first adsorption cylinder 41 and the second adsorption cylinder 42 are arranged alternately. The first adsorption cylinder 41 is used to adsorb and transport the material from the conveying mechanism to the first folding mechanism 2. The second adsorption cylinder 42 is used to adsorb and transport the material from the first folding mechanism to the second folding mechanism 3.
[0040] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the long-side folding mechanism 21 includes: two symmetrically arranged first movable frames, two long-side folding plates 211, two first placement plates 24, and two sets of long-side driving components. The two first placement plates 24 are respectively disposed on the corresponding first movable frames, the two long-side folding plates 211 are respectively disposed on the corresponding first movable frames, the two first placement plates 24 are located between the two long-side folding plates 211, and the two sets of long-side driving components are respectively disposed on the corresponding first movable frames and drive the corresponding long-side folding plates 211 to fold.
[0041] Specifically, such as Figure 5 and Figure 6As shown, the two first moving frames are frames welded together by multiple connecting plates. A material feeding space is reserved between the two first placement plates 24. The short side folding mechanism 22 is located in the material feeding space, which can realize the long side folding of the shell and then move it down to the short side folding mechanism 22 for short side folding. In this way, the short side folding mechanism 22 is located below the long side folding mechanism 21, which achieves the effect of saving space and eliminating the need for long-distance transmission to the next station for folding, thus saving folding time and improving folding efficiency.
[0042] The two sets of long-side drive components have identical structures, with each set including a long-side pushing cylinder and a long-side lifting cylinder. Both the long-side pushing cylinder and the long-side lifting cylinder are mounted on the first movable frame, thereby pushing the long-side folding plate to move up and down and left and right to fold the material. In this process, since the material (which already has the gray board and face paper pasted on) needs to be folded along its long side, the first adsorption cylinder 41 adsorbs the material onto the two first placement plates 24 for support. At this time, the top surface of the long side folding plate 211 needs to be flush with the top surface of the first placement plate 24 so that the edge of the material (the edge that will cover the gray board) can rest on the long side folding plate 211. The long side lifting cylinder drives the long side folding plate 211 to rise, at which point the edge is bent perpendicular to the gray board. When the long side folding plate 211 rises to about 0.1mm above the gray board at its bottom, the long side pushing cylinder pushes the long side folding plate 211 towards the first placement plate 24 until it moves above the first placement plate 24. The long side folding plate 211 then pushes the edge of the material onto the gray board, completing the folding. This long side driving component can be controlled independently or synchronously. It is important to note that the length of the gray board must be the same as the distance between the edges of the two first placement boards 24 that are furthest from each other in order to accurately fold the face paper (referring to the leather) onto the gray board.
[0043] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the long side folding mechanism 21 also includes a long side distance adjustment component for adjusting the movement of the long side folding plate 211. The long side distance adjustment component includes a first distance main adjustment component 214 and a first distance secondary adjustment component 215. The first distance main adjustment component 214 is disposed at one end of the first moving frame, and the first distance secondary adjustment component 215 is disposed at the end of the first moving frame away from the first distance main adjustment component 214.
[0044] In this embodiment, the first distance main adjustment component 214 includes a long side distance adjustment motor, a first gear, and a first rack 2143. The rack is mounted on the frame, and the first gear is rotatably mounted on the first movable frame. One end of the first gear is provided with a first grooved wheel, which is connected to the long side distance adjustment motor.
[0045] The first distance adjustment component 215 includes a second gear and a second rack 2151. The second rack 2151 is symmetrically arranged with the first rack 2143 and is disposed on the frame. The second gear is symmetrically arranged with the first gear at the end of the first moving frame away from the first gear. The first gear and the second gear are connected by a rotating shaft.
[0046] Specifically, when it is necessary to adjust the distance between the long side folding plates 211, the long side distance adjustment motor drives the first grooved wheel to rotate, the first grooved wheel drives the first gear to rotate, the first gear drives the shaft connection, the first gear drives the second gear to rotate, thereby realizing the first gear meshing with the first rack 2143 and the second gear meshing with the second rack 2151, thereby driving the two first moving frames to move relative to each other.
[0047] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the long side folding mechanism 21 also includes an ear-cutting mechanism, which includes four ear-cutting cylinders arranged in a four-corner array. The four ear-cutting cylinders are distributed on two symmetrically arranged long side folding plates 211.
[0048] Specifically, each long-side folding plate 211 is symmetrically equipped with two ear-cutting cylinders. A cutting blade is provided on the lever of the ear-cutting cylinder. When the lever of the ear-cutting cylinder extends, the four corners of the material can be cut, which facilitates the corner folding of the material.
[0049] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the short-side folding mechanism 22 includes: two symmetrically arranged second movable frames 224, two short-side folding plates 221, two second placement plates 223, and two sets of short-side driving components. The two second placement plates 223 are respectively disposed on the corresponding second movable frames 224, the two short-side folding plates 221 are respectively disposed on the corresponding second movable frames 224, the two second placement plates 223 are located between the two short-side folding plates 221, and the two sets of short-side driving components are respectively disposed on the corresponding second movable frames 224 and drive the corresponding short-side folding plates 221 to fold.
[0050] Specifically, such as Figure 5 and Figure 6 As shown, the two second movable frames 224 are U-shaped frames welded together from multiple connecting plates. These U-shaped frames are installed upside down at the bottom of the frame body, which has a slide rail. A slider is located at the end of the U-shaped opening of the U-shaped mounting frame and slides along the slide rail. The two movable frames are controlled by a motor to move in opposite directions, accommodating materials of different widths. A material feeding space is reserved between the two second placement plates 223, and a material conveyor belt is located below this space. After the short-side folding mechanism 22 folds the casing, the casing falls onto the material conveyor belt and is then conveyed out. This arrangement of the conveyor belt below the short-side folding mechanism 22 saves space and avoids long-distance transport to the next workstation, saving folding time and improving folding efficiency. A pressure roller is located in the conveying direction of the material conveyor belt to flatten the conveyed material.
[0051] The two sets of short-side drive components have identical structures, each including a short-side pushing cylinder. The short-side pushing cylinder is mounted on the second movable frame 224, allowing it to push the short-side folding plate 221 back and forth, thus folding the material's short side. Specifically, since the material (which has already undergone long-side folding) needs to be folded, the second adsorption cylinder 42 adsorbs the material onto two second placement plates 223 for support. The short-side folding plate 221 is offset from the second placement plates 223, with the distance between the bottom of the short-side folding plate 221 and the top of the second placement plate 223 exceeding the gray board by approximately 0.1 mm. The short-side pushing cylinder pushes the short-side folding plate 221 towards the second placement plate 223 until it is above the second placement plate 223, at which point the short-side folding plate 221 pushes the edge of the material onto the gray board, completing the folding. This short-side drive component can be controlled independently or synchronously. It is important to note that the length of the gray board must be the same as the distance between the edges of the two second placement boards 223 away from each other in order to accurately fold the face paper (referring to the leather) onto the gray board.
[0052] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the drawer box mold 323 station includes a movable moving component and a drawer box mold 323 disposed on the moving component. The drawer box forming station 31 includes two symmetrically arranged forming plates. A forming space is provided between the two forming plates for the drawer box mold 323 to pass through. Symmetrically arranged baffles are provided in the forming space. Drawer box material is disposed on the forming plates. Under the action of the moving component, the drawer box mold presses down on the drawer box material and passes through the forming space, so that the drawer box material enters between the two baffles and partially wraps around the drawer box mold 323. The drawer box mold 323 and the drawer box material fall into the drawer box folding component 33.
[0053] Specifically, such as Figure 7 As shown, the moving component includes two symmetrically arranged parallel slide rails 321 and a vertical slide rail 322. The vertical slide rail 322 is slidably mounted on the symmetrically arranged parallel slide rails 321 via a sliding seat. A drive motor (using an existing motor compatible with the slide rails, not described in detail here) is mounted on the sliding seat. Driven by the sliding seat, the vertical slide rail 322 can move closer to or further away from the molding plate. A lead screw 225 is provided on the vertical slide rail 322, and a moving seat 3222 is provided on the lead screw 225. A detachable drawer box mold 323 is mounted on the moving seat 3222. The exemplary drawer box mold 323 can be fixed to the moving seat 3222 with bolts. Thus, the moving component can drive the drawer box mold 323 to move up and down and back and forth, enabling the drawer box mold 323 to move above the molding plate and then move the drawer box material downwards. For example, taking a rectangular drawer box as an example in this application, the material is folded on one side by one of the long side folding plates 211 on the long side folding mechanism 21 in the above embodiment. After the folding is completed, the material is adsorbed onto the forming plate by the second adsorption cylinder 42, so that the folded side faces the drawer box mold 323. During the adsorption process, the falling position of the adsorption cylinder has been marked in advance, driving the moving component to move, so that the drawer box mold 323 moves above the forming plate and presses down to drive the drawer box material to move downward. At this time, under the limitation of the baffle, the drawer box material is partially wrapped around the drawer box and falls into the drawer box folding station.
[0054] In some embodiments, such as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the drawer box folding station includes a drawer box gray board bending plate 331, a drawer box side folding push plate 332, a drawer box first bottom folding push plate 333, a drawer box second bottom folding push plate 334, a drawer box third bottom folding push plate 335, and a drawer box folding drive assembly corresponding to each push plate. The drawer box gray board bending push plate is symmetrically arranged with the drawer box side folding push plate 332. The drawer box first bottom folding push plate 333 is symmetrically arranged with the drawer box second bottom folding push plate. The drawer box first bottom folding push plate 333 is adjacent to the drawer box gray board bending push plate and the angle between them is 90°. The drawer box second bottom folding push plate 334 is adjacent to the drawer box side folding push plate 332 and the angle between them is 90°. The drawer box third bottom folding push plate 335 is located on the same plane and perpendicular to the drawer box first bottom folding push plate 333 and the drawer box second bottom folding push plate 334.
[0055] Specifically, the drawer box gray board bending pusher has an L-shaped structure. The bending plate of the drawer box gray board bending pusher is parallel to the top of the mold. Driven by the drawer box edge folding drive component corresponding to the drawer box gray board bending plate 331, the drawer box gray board bending pusher moves towards the drawer box material. At this time, the L-shape of the drawer box gray board bending pusher pushes the gray board of the drawer box material to the top of the mold, so that the gray board wraps the entire mold. Then, driven by the drawer box edge folding drive component corresponding to the drawer box side edge folding pusher 332, the edge of the face paper is folded and wrapped in the gray board. On the board, driven by the drawer box folding drive assembly corresponding to the first bottom folding push plate 333, one side of the bottom paper of the drawer box is folded. Then, driven by the drawer box folding drive assembly corresponding to the second bottom folding push plate 334, one side of the bottom paper of the drawer box is folded. Then, driven by the drawer box folding drive assembly corresponding to the third bottom folding push plate 335, one side of the bottom paper of the drawer box is folded, completing the production of the drawer box shell. The paper is pre-cut to perfectly fit the folding mechanism of this equipment. The drawer box folding drive assembly uses a combination of slide rails and sliders, driven by a drive motor, which will not be described in detail here.
[0056] The specific implementation process of this application is as follows:
[0057] For example, the process of folding the edges of the casing includes: a first conveying mechanism 1 is connected to a device for bonding face paper and gray board, wherein both face paper and gray board have been pre-processed, for example, the face paper is cut according to requirements and the gray board is grooved according to requirements. The first conveying mechanism 1 conveys the material with the face paper and gray board bonded together, and places the material on the first placement plate 24 of the long edge folding mechanism 21 through the first adsorption cylinder 41 (wherein the two first placement plates 24 have been pre-set according to the size of the material to be folded, and the distance between the two first placement plates 24 is driven by a drive motor, as in the specific drive process of the above embodiment, which will not be described in detail here), and then the ear-cutting mechanism is driven to cut the four corners of the material, and then the long edge pushing cylinder is driven to push the long edge folding plate 211 towards the first placement plate 24 until it moves above the first placement plate 24, and the long edge folding plate 211 pushes the edge of the material onto the gray board, completing the long edge folding. The material after the long side is folded is adsorbed by the second adsorption cylinder 42. By driving the long side distance adjustment component, the two first moving frames are moved apart, so that the first placement plate 24 is away from the material. The second adsorption cylinder 42 presses down, pushing the material after the long side is folded onto the second placement plate 223 of the short side folding mechanism 22. The short side pushing cylinder pushes the short side folding plate 221 to move towards the second placement plate 223 until it moves above the second placement plate 223. The short side folding plate 221 pushes the edge of the material onto the gray plate, completing the short side folding, which is to say, completing all the folding of the shell. The shell is adsorbed by the second adsorption cylinder 42, and the short side driving component is driven to move the two second moving frames 224 apart. The second adsorption cylinder 42 descends, placing the shell on the material conveyor belt and conveying it out.
[0058] For example, the process of folding the edge of a drawer box includes: a first conveying mechanism 1 is connected to a device for bonding face paper and gray board, wherein both face paper and gray board have been pre-processed, for example, the face paper is cut according to requirements and the gray board is grooved according to requirements. The first conveying mechanism 1 conveys the material with the face paper and gray board bonded together, and places the material on the first placement plate 24 of the long side folding mechanism 21 through the first adsorption cylinder 41 (wherein the two first placement plates 24 have been pre-set according to the size of the material to be folded, and the distance between the two first placement plates 24 is driven by a drive motor, as in the specific drive process of the above embodiment, which will not be described in detail here), and then drives one of the long side folding plates 211 to move towards the first placement plate 24 until it moves above the first placement plate 24, and the long side folding plate 211 pushes the edge of the material onto the gray board to complete the long side folding. The second adsorption cylinder 42 places the folded edge of the material toward the drawer box mold 323. Driven by the drawer box edge folding drive assembly corresponding to the drawer box gray board bending plate 331, the drawer box gray board bending push plate moves toward the drawer box material. At this time, the L-shape of the drawer box gray board bending push plate pushes the gray board of the drawer box material to the top of the mold, so that the gray board wraps the entire mold. Then, driven by the drawer box edge folding drive assembly corresponding to the drawer box side edge folding push plate 332, the edge of the face paper is folded and wrapped around the gray board. Then, the drawer box is pulled out of the drawer. Driven by the drawer box folding drive assembly corresponding to the first bottom folding push plate 333, one side of the bottom paper of the drawer box is folded. Then, driven by the drawer box folding drive assembly corresponding to the second bottom folding push plate 334, one side of the bottom paper of the drawer box is folded. Finally, driven by the drawer box folding drive assembly corresponding to the third bottom folding push plate 335, one side of the bottom paper of the drawer box is folded, completing the production of the drawer box shell. The paper panels are all pre-cut to perfectly fit the folding mechanism of this equipment.
[0059] The beneficial effects of this application are:
[0060] Breaking away from the limitations of traditional equipment that can only produce casings or drawer boxes individually, this machine utilizes a dual-mode operation of the first folding mechanism (simultaneous operation of the long and short side folding mechanisms to produce casings, and single-mechanism operation to produce partial folding material), combined with the drawer box forming and folding processes of the second folding mechanism. This allows a single machine to complete the entire production process for two products, eliminating the need for companies to purchase separate casing and drawer box production equipment, directly reducing costs associated with equipment procurement, space occupation, and maintenance. The production processes for both products share basic components such as the first conveying mechanism and adsorption mechanism, achieving component reuse, improving overall equipment utilization, and further reducing overall production costs. The short side folding mechanism is located within the material feeding space of the long side folding mechanism, allowing the finished casing to fall directly to the short side folding station without long-distance transport. A material conveyor belt is directly installed below the short side folding mechanism, allowing the finished casing to fall directly, eliminating the need for additional transfer structures, significantly reducing the overall footprint of the equipment, and adapting to the layout requirements of small and medium-sized production sites. A movable adsorption mechanism (with alternating double adsorption cylinders) enables precise and rapid material transfer between the first conveying mechanism, the first folding mechanism, and the second folding mechanism, replacing manual handling and preventing material shifting or damage during transfer. The translation and lifting movements of the adsorption cylinders are synchronized with the operating rhythm of each folding and forming mechanism, achieving automated connection between workstations and eliminating waiting time between processes. The long-side folding mechanism, the short-side folding mechanism, and the drawer box folding assembly are all independent modular structures. The drive and adjustment components of each mechanism are independent, facilitating equipment assembly, debugging, and subsequent maintenance. If a mechanism malfunctions, it can be disassembled and repaired individually without affecting the temporary use of other mechanisms, reducing equipment downtime losses. The first conveying mechanism is equipped with a straightening cylinder, which can precisely straighten the material to be folded to the preset position, ensuring the alignment accuracy of subsequent folding and forming processes from the feeding end, and avoiding folding misalignment and poor forming caused by material offset. The folding action of the long side folding plate is precisely controlled by a long side push cylinder and a lifting cylinder. During folding, the bottom of the long side folding plate extends 0.1mm beyond the gray board before pushing the folding. The short side folding plate and the second placement plate also maintain a precise height misalignment, ensuring that the face paper is tightly and flatly wrapped on the gray board, and there are no curling or offset issues during folding. The drawer box forming station is equipped with symmetrical baffles, which limit the material when the mold is pressed down to form, ensuring the positional accuracy of the material partially wrapping the mold, laying the foundation for the precise folding of the subsequent drawer box folding components. The push plates of the drawer box folding components are arranged at 90° vertically or symmetrically, and with the help of a dedicated drive component, the drawer box gray board wrapping, side folding, and bottom multi-face folding are completed in steps with precision, resulting in a high degree of structural regularity in the finished drawer box. • The long side folding mechanism is equipped with a long side distance adjustment component (main + secondary adjustment). The motor drives the gear rack to mesh, which drives the two first moving frames to move relative to each other. The distance between the long side folding plate and the first placement plate can be flexibly adjusted to adapt to materials of different lengths and specifications to be folded.
[0061] The two second movable frames of the short side folding mechanism are driven by motors to move the slide rail sliders, which can adjust the distance between the short side folding plate and the second placement plate to accommodate materials of different widths.
[0062] The drawer box mold is detachable and fixed to the moving base with bolts. The mold can be changed according to the production needs of different drawer box specifications without modifying the main structure of the equipment, making it suitable for the production of various product specifications. The drive components (cylinders, motors), adsorption mechanism, and conveying mechanism of each folding mechanism can all be automatically controlled. Some components support individual or synchronous control, which can be flexibly adjusted according to production needs, replacing traditional manual folding and forming operations, significantly reducing manual intervention, lowering labor costs, and reducing the error rate of manual operation.
[0063] The long-side folding mechanism integrates an ear-cutting mechanism (four-corner array ear-cutting cylinder), which can directly cut the four corners of the material before folding, eliminating the need for a separate cutting station, reducing process steps, and saving production time.
[0064] The long and short side folding processes in the leather casing production are seamlessly integrated, while the folding, forming, and multi-step folding processes in the drawer box production are completed continuously. The actions in each process are seamlessly connected, significantly shortening the production cycle of a single product and increasing the equipment's capacity per unit time. Pressure rollers are installed along the material conveyor belt to flatten the finished leather casings during transport, preventing warping and deformation after folding and further ensuring the flatness of the finished product. Simultaneously, material movement at each station is accomplished through mechanical actions of adsorption, pressing, and pushing, reducing scratches and damage to the finished products caused by manual contact and improving the overall product yield.
