Description

Technical Field

[0001] This invention relates to the edge-wrapping assembly of a casing machine. Background Technology

[0002] The shell-making machine is used for shell production. It uses cardboard and face paper as the main materials to be conveyed for subsequent edge wrapping. The bottom surface of the cardboard is glued with the face paper, and then the glued material is conveyed for subsequent edge wrapping. The face paper (glued to) the bottom surface of the cardboard is folded over and wrapped around the edge of the cardboard to complete the corresponding edge wrapping.

[0003] In cardboard wrapping machines, the edges of cardboard need to be edged with face paper. For example, in equipment such as CN218257126U (a novel cardboard wrapping machine), the four edges of the cardboard are edged separately. First, a left- and right-hand torsional belt conveys the material forward, edged the left and right edges of the cardboard, and then continues conveying material to edge the front and rear edges. When a conveyor belt is used for further material feeding, corresponding edge-wrapping mechanisms can be configured at the inlet and outlet ends of the conveyor belt to cooperate in edge-wrapping the front and rear edges of the cardboard. For instance, after the material is fed onto the conveyor belt, the conveyor belt moves forward, bringing the rear edge of the cardboard to the inlet end of the conveyor belt. At this point, the conveyor belt pauses once to ensure the rear edge of the cardboard is at the inlet end, thus completing the edge-wrapping of the rear edge. After the rear edge is finished, the conveyor belt resumes its forward movement to continue conveying material. If folding blocks (such as the folding hammer of the front folding mechanism in CN218257126U, the folding block in the front edge-wrapping mechanism of the CN210553353U, etc.) are used in conjunction with the front edge wrapping during the forward conveying process of the conveyor belt, there are problems such as loose edge wrapping and difficulty in adapting to irregular edge wrapping requirements. Alternatively, if the conveyor belt stops during the forward movement and another method of edge binding is used, the conveyor belt will stop multiple times (e.g., twice) during the edge binding process of a piece of cardboard, affecting the speed and efficiency.

[0004] In addition, different cardboard dimensions (such as front and back lengths) result in different relative positions of the front and back edges. The conveyor belt needs to transport the cardboard multiple times (such as twice) to ensure that the front and back edges reach the corresponding positions for the edge-wrapping operation.

[0005] In addition, the edge-sealing method using an edge-sealing plate in conjunction with folded face paper to cover the edge of the cardboard has a relatively good effect, resulting in a tighter edge and meeting the edge-sealing requirements of some irregular edges (such as beveled edges, triangular V-shaped edges, and curved edges). For example, the edge-sealing plate is initially located on the underside of the cardboard. After the material is delivered, the edge-sealing plate is driven upward, folding the face paper that extends beyond the edge of the cardboard upward. Then, the edge-sealing plate is driven to move towards the center of the cardboard, folding the upward-folded face paper towards the cardboard to cover the upper side of the cardboard, thus completing the edge sealing. Afterward, the edge-sealing plate retracts to its original position to await the next operation. The edge-sealing mechanism using an edge-sealing plate requires a certain amount of space for assembly. The entire edge-sealing mechanism is mounted on the equipment base in a support-type arrangement. The edge-sealing plate's retraction waiting position and initial edge-sealing position are located below the cardboard in a low position. During operation, it moves directly upwards (vertically or obliquely). The entire edge-sealing mechanism can be positioned next to the conveyor belt, between the conveyor belts, in the concave part of the conveyor belt, or at the edge of the worktable. However, in situations where the corresponding space of the conveyor belt or the edge-sealing worktable is limited, the entire edge-sealing mechanism is difficult to arrange. The edge-sealing mechanism itself occupies the entire bottom space of the equipment, resulting in a larger overall size of the equipment and requiring more space for assembly. Maintenance and disassembly are inconvenient. Summary of the Invention

[0006] In view of the technical problems existing in the background art, the present invention aims to provide a more efficient edge-binding assembly for a casing machine that combines material conveying and edge-binding.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The edge-wrapping assembly of the casing machine has front and rear edge-wrapping units. The front and rear edge-wrapping units include an intermittent conveyor belt and a front edge-wrapping mechanism and a rear edge-wrapping mechanism that operate in parallel and cooperatively. The conveyor belt is mounted on a frame, and a drive shaft is provided on the frame for the conveyor belt to wound around. The drive shaft includes a front rotating shaft and a rear rotating shaft arranged opposite to each other. The front rotating shaft is located at the discharge end of the conveyor belt, and the rear rotating shaft is located at the inlet end of the conveyor belt. The frame also has a bracket with adjustable front and rear positions. The bracket has a guide assembly for the conveyor belt to turn and wound around. The guide assembly includes a first guide shaft and a second guide shaft, a rear rotating shaft, a first guide shaft, and a second guide shaft. The shaft and the front rotating shaft are arranged from back to front. The guide assembly also includes at least one steering shaft. The steering shaft is connected to the outside of the conveyor belt. The first guide shaft and the second guide shaft are connected to the inside of the conveyor belt. The steering shaft is located below the first guide shaft and the second guide shaft. The conveyor belt has a downwardly recessed edge-wrapping operation clearance space between the first guide shaft and the second guide shaft. The feed end of the conveyor belt is equipped with a first edge-wrapping station. The first edge-wrapping station is equipped with a rear edge-wrapping mechanism. The support is equipped with a second edge-wrapping station. The second edge-wrapping station is correspondingly set in the edge-wrapping operation clearance space. The second edge-wrapping station is equipped with a front edge-wrapping mechanism. The front edge-wrapping mechanism is connected to the support.

[0008] The following optimizations or supplementary explanations can be made to the above technical solutions.

[0009] For example, the edge-wrapping assembly of the casing machine also has left and right edge-wrapping units, which include a left twist edge-wrapping belt and a right twist edge-wrapping belt. The front and rear edge-wrapping units are connected in front of the left and right edge-wrapping units. The material movement path from the input of the left and right edge-wrapping units to the output of the front and rear edge-wrapping units is a straight path. The left and right edge-wrapping units and the front and rear edge-wrapping units can also be connected by feeding rollers.

[0010] The first edge-binding station is located between the left and right edge-binding units and the front and rear edge-binding units. The rear edge-binding mechanism is located between the left and right edge-binding units and the front and rear edge-binding units, and the feeding roller is located in the preceding position of the rear edge-binding mechanism.

[0011] For example, the rear edge-wrapping mechanism includes a first receiving edge-wrapping support plate and a first edge-wrapping plate for cooperating with the first receiving edge-wrapping support plate to complete the edge-wrapping operation. The first receiving edge-wrapping support plate is configured at the feed end of the conveyor belt and is connected to the conveyor belt. The front edge-wrapping mechanism includes a second receiving edge-wrapping support plate and a second edge-wrapping plate for cooperating with the second receiving edge-wrapping support plate to complete the edge-wrapping operation. The second receiving edge-wrapping support plate is configured at the feed output end of the conveyor belt at the first guide shaft and is connected to the second receiving edge-wrapping support plate. The second receiving edge-wrapping support plate is located in the edge-wrapping operation clearance space and is connected to the bracket.

[0012] For example, the first edge-binding plate is designed to lift and move forward and backward, and the second edge-binding plate is designed to lift and move forward and backward. In addition, a first paper-pressing component is provided above the first receiving edge-binding tray, and the first paper-pressing component is drivenly connected to a first lifting paper-pressing drive component. A second paper-pressing component is provided above the second receiving edge-binding tray, and the second paper-pressing component is drivenly connected to a second lifting paper-pressing drive component. The first receiving edge-binding tray and the second receiving edge-binding tray are both arranged horizontally. The upper side of the second receiving edge-binding tray is also provided with a lifting paper-stop positioning component for blocking the paperboard from moving forward. The lifting paper-stop positioning component is drivenly connected to the lifting paper-stop drive component.

[0013] The conveyor belt between the rear rotating shaft and the first guide shaft is a single-piece material conveying, stopping, and edge-wrapping processing position.

[0014] In addition, the conveyor belt is equipped with cardboard positioning side gauges arranged on the left and right above the area between the rear rotating shaft and the first guide shaft. The first corner-cutting component is provided above the first receiving edge-cutting plate, and the first corner-cutting component is arranged on the left and right sides. The second corner-cutting component is provided above the second receiving edge-cutting plate, and the second corner-cutting component is arranged on the left and right sides. The first corner-cutting component is designed to lift and move left and right, and the second corner-cutting component is designed to lift and move left and right.

[0015] Specifically, the first edge banding plate is installed on the first lifting seat, the first lifting seat is installed on the first front-to-back moving frame that is set to move back and forth, the first edge banding plate is flush with or lower than the first receiving edge banding support plate at the edge banding starting position, the first edge banding plate is located at the upper end of the first lifting seat, and the first front-to-back moving frame and the first lifting seat are not higher than the first receiving edge banding support plate before the edge banding operation; the first front-to-back moving frame is set to move horizontally back and forth or to move forward obliquely from high to low when edge banding.

[0016] For example, the front edge-wrapping mechanism also includes an edge-wrapping support frame, which is located above the second receiving edge-wrapping tray. The edge-wrapping support frame is equipped with a combined movable frame that drives the second edge-wrapping plate to rise, fall, and move back and forth. The second edge-wrapping plate is connected to the combined movable frame. The second edge-wrapping plate has a preparatory waiting area and an edge-wrapping operation area, with the preparatory waiting area positioned above the edge-wrapping operation area.

[0017] Specifically, the combined movable frame includes a second lifting seat and a second forward and backward moving frame, the second lifting seat and the second forward and backward moving frame being connected in cooperation; the edging support frame is provided with a first guide rail running forward and backward, the second forward and backward moving frame is disposed on the first guide rail, the edging support frame is also provided with a first motor, the first motor is driven by the second forward and backward moving frame, the first motor drives the second forward and backward moving frame to move forward and backward on the edging support frame; the second forward and backward moving frame is provided with a vertically arranged second guide rail, the second lifting seat is disposed on the second guide rail, the second forward and backward moving frame is also provided with a second motor, the second motor... The machine is connected to the second lifting seat via a transmission. The second motor drives the second lifting seat to move up and down on the second front and rear moving frame. The first guide rail is set horizontally in a front-to-back direction. Alternatively, the first guide rail is set at an angle in front and back. When the second edge banding plate moves forward and edge banding, it tilts and descends. The second edge banding plate moves up to the preparatory waiting area and then backs up to wait. The second edge banding plate moves down to the edge banding operation area to cooperate in performing the edge banding operation. The edge of the second receiving edge banding tray has an edge banding starting position where the second edge banding plate descends to the position. The second edge banding plate is flush with or lower than the second receiving edge banding tray at the edge banding starting position.

[0018] For example, the frame includes side wall panels arranged on the left and right, and longitudinal guide rails are provided on the frame for the support to move back and forth. The support includes support plates arranged on the left and right. The conveyor belt is connected to an intermittent feeding drive device, which includes a feeding motor, which is a feeding servo motor. The frame is also provided with a front auxiliary shaft and a rear auxiliary shaft arranged for the conveyor belt to cooperate with it. The front auxiliary shaft is located below the front shaft, and the rear auxiliary shaft is located below the rear shaft. The installation height of the steering shaft is higher than that of the front auxiliary shaft and the rear auxiliary shaft. The axes of the rear shaft and the front shaft are arranged laterally on the left and right. The axes of the first guide shaft, the second guide shaft, and the steering shaft are all arranged laterally on the left and right. The conveyor belt is recessed downward between the first guide shaft and the second guide shaft and wound around the steering shaft. The recessed conveyor belt forms the edge-wrapping operation clearance space. The steering shaft is distributed front and rear.

[0019] The conveyor belt is closed and looped in a circle; the first feeding area is located between the rear rotating shaft and the first guide shaft, and the first feeding area is set up for lateral feeding; the second feeding area is located between the second guide shaft and the front rotating shaft; the edge-wrapping operation clearance space is located between the first and second feeding areas, and the feeding of the first and second feeding areas is connected; the material passage path is located above the edge-wrapping operation clearance space; the second feeding area is set up for lateral feeding.

[0020] In addition, an auxiliary material feeding component is provided in the clearance space of the edge wrapping operation. The auxiliary material feeding component is installed on the bracket and is located between the first guide shaft and the second guide shaft. The auxiliary material feeding component is raised and lowered on the bracket. The auxiliary material feeding component is driven by a lifting material support drive component. The auxiliary material feeding component is connected to the bracket through the lifting material support drive component. The auxiliary material feeding component adopts a material feeding plate, material feeding roller, or material feeding shaft. When the auxiliary material feeding component rises to a high position, it connects with the feeding path of the conveyor belt.

[0021] The beneficial effects of this invention are as follows: In the edge-wrapping assembly of the casing machine, the front edge-wrapping mechanism and the rear edge-wrapping mechanism can cooperate and coordinate to perform edge-wrapping operations. The relative front and rear positions on the frame can be adjusted by the bracket to meet the material movement and conveying needs of different length and size specifications. This allows the front and rear sides of the same batch of materials to be located at the front and rear of the area between the rear rotating shaft and the first guide shaft of the conveyor belt, respectively. The conveyor belt has space and edge-wrapping mechanisms on both the front and rear sides of the material for edge-wrapping operations, so that the front and rear sides can cooperate to perform edge-wrapping operations. The conveyor belt only needs to stop once during the material movement and conveying process to cooperate with the front and rear sides of the material for edge-wrapping operations. The conveyor belt not only conveys more efficiently, but also improves edge-wrapping efficiency. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the implementation of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Referring to the accompanying drawings, in this embodiment, the edge-wrapping assembly of the shell-making machine has front and rear edge-wrapping units for wrapping the front and rear edges of the material. The front and rear edge-wrapping units include an intermittent conveyor belt 1 and a front edge-wrapping mechanism 50 and a rear edge-wrapping mechanism 40 that operate in parallel and in coordination. The conveyor belt 1 is used to intermittently move and convey the material (i.e., the cardboard with the face paper pasted on the lower side) forward. The parallel and coordinated edge-wrapping operation of the front edge-wrapping mechanism 50 and the rear edge-wrapping mechanism 40 can cooperate to perform edge-wrapping operations simultaneously for greater efficiency. The conveyor belt 1 is mounted on a frame (not shown in the figure). The frame is equipped with a drive shaft for the conveyor belt 1 to be wound around, so as to coordinate with the arrangement of the conveyor belt 1. The drive shaft includes a front rotating shaft 22 and a rear rotating shaft 21 arranged opposite to each other. The front rotating shaft 22 is located at the discharge end of the conveyor belt 1, and the rear rotating shaft 21 is located at the feed end of the conveyor belt 1. The conveyor belt 1 intermittently transports the material used for edge wrapping, with the material moving from the feed end to the discharge end. The frame is also equipped with a support 3 whose front-to-back position is adjustable according to requirements. The support frame 3 is equipped with a guide assembly 30 for the conveyor belt 1 to be turned and wound around. The guide assembly 30 is also adjusted and set in the front and back position along with the support frame 3. The guide assembly 30 can cooperate to turn and wound the conveyor belt 1 and guide the arrangement of the conveyor belt 1. The guide assembly 30 includes a first guide shaft 31 and a second guide shaft 32. The rear rotating shaft 21, the first guide shaft 31, the second guide shaft 32, and the front rotating shaft 22 are arranged from back to front. Typically, the bracket 3 is located between the front rotating shaft 22 and the rear rotating shaft 21 (e.g., in the middle area) for front-to-back position adjustment. The guide assembly 30 also includes at least one steering shaft 33, which is connected to the outer side of the conveyor belt 1, while the first guide shaft 31 and the second guide shaft 32 are connected to the inner side of the conveyor belt 1. The steering shaft 33 is located below the first guide shaft 31 and the second guide shaft 32. The conveyor belt 1 is between the first guide shaft 31 and the second guide shaft 32 and is supported by the steering shaft 33 to form a downward recess. The downward recess serves as a clearance space 10 for edge wrapping operations, so as to avoid obstacles during edge wrapping operations. That is, the conveyor belt 1 has a downward recessed clearance space 10 for edge wrapping operations between the first guide shaft 31 and the second guide shaft 32. The conveyor belt 1 on the frame is guided and steered by the guide assembly 30 (including the first guide shaft 31, the second guide shaft 32 and the steering shaft 33) to form the downward recessed clearance space 10 for edge wrapping operations. The guide assembly 30 is set on the support 3, and the support 3 can be adjusted in a relatively adjustable position on the frame, so that the guide assembly 30 can move back and forth with the support 3, and the relative position of the downward recessed clearance space 10 for edge wrapping operations can also be adjusted back and forth.

[0032] The conveyor belt 1 has a first edge-sealing station 4 at its feed end, with a rear edge-sealing mechanism 40 at this station. A second edge-sealing station 5 is mounted on the support 3, corresponding to the edge-sealing operation clearance space 10. This means the conveyor belt 1 has two edge-sealing stations in the area between the rear rotating shaft 21 and the first guide shaft 31. A front edge-sealing mechanism 50 is located at the second edge-sealing station 5 and is connected to the support 3. The front edge-sealing mechanism 50 can be adjusted in position along with the support 3. The rear edge-sealing mechanism 40 can be mounted on the frame.

[0033] Its working principle is as follows: In the edge-wrapping assembly of the casing machine, the front edge-wrapping mechanism 50 and the rear edge-wrapping mechanism 40 can cooperate and coordinate the edge-wrapping operation. The relative front and rear positions of the adjustment bracket 3 on the frame are adjusted so that the area between the rear rotating shaft 21 and the first guide shaft 31 of the conveyor belt 1 can match the front and rear length dimensions of the same batch of materials. When the material is input onto the conveyor belt 1, the conveyor belt 1 will move forward to transport the material for edge-wrapping (i.e., the cardboard with the paper pasted on the lower side). After the material is moved into place on the conveyor belt 1, the front side of the material is located in the downwardly recessed edge-wrapping operation avoidance space 10, and the rear side of the material is located at the rear rotating shaft 21 of the conveyor belt 1 (i.e., the starting point of the conveyor belt 1). The conveyor belt 1 has space on both the front and rear sides of the material for edge-wrapping operation so that the front edge-wrapping mechanism 50 and the rear edge-wrapping mechanism 40 can cooperate and coordinate the edge-wrapping operation. For different batches of materials, when the front and rear length dimensions of the materials are different, the bracket 3 can be adjusted relative to the front and rear positions on the frame to adapt them. This ensures that after the materials of the same batch are moved into place on the conveyor belt 1, the front side of the material is located in the downwardly recessed edge-wrapping operation clearance space 10, so that the front edge-wrapping mechanism 50 can cooperate with the edge-wrapping operation. In addition, the rear side of the material is located at the rear pivot 21 of the conveyor belt 1 (i.e., the starting point of the conveyor belt 1), so that the rear edge-wrapping mechanism 40 can cooperate with the edge-wrapping operation. The conveyor belt 1 has space and edge-wrapping mechanisms on both the front and rear sides of the material for edge-wrapping operations, so that the front and rear sides can be edge-wrapped together. The conveyor belt 1 only needs to stop once during the material movement to cooperate with the edge-wrapping operation on both the front and rear sides of the material. The conveyor belt 1 not only conveys more efficiently, but also improves the edge-wrapping efficiency.

[0034] In the edge-wrapping assembly of this casing machine, the front edge-wrapping mechanism 50 and the rear edge-wrapping mechanism 40 can cooperate and work together in parallel edge-wrapping operations. They can be adjusted relative to each other on the frame via the bracket 3 to meet the material movement and conveying needs of materials of different lengths and sizes. This allows the front and rear sides of the same batch of materials to be located at the front and rear of the area between the rear rotating shaft 21 and the first guide shaft 31 of the conveyor belt 1, respectively. The conveyor belt 1 has space and edge-wrapping mechanisms on both the front and rear sides of the material for edge-wrapping operations, so that the front and rear sides can work together in edge-wrapping operations. The conveyor belt 1 only needs to stop once during the material movement and conveying process to cooperate with the front and rear sides of the material for edge-wrapping operations. The conveyor belt 1 not only conveys more efficiently, but also helps to improve edge-wrapping efficiency.

[0035] Based on the above embodiments, the following optimizations or further explanations can be made.

[0036] For example, the edge-wrapping assembly of the casing machine also has left and right edge-wrapping units (not shown in the figure). The left and right edge-wrapping units include a left twist edge-wrapping belt and a right twist edge-wrapping belt, which is a mature technology. The front and rear edge-wrapping units are connected to the left and right edge-wrapping units in the preceding position. The left and right edge-wrapping is performed first, followed by the front and rear edge-wrapping. The material movement path from the input of the left and right edge-wrapping units to the output of the front and rear edge-wrapping units is a straight path. In addition, the left and right edge-wrapping units and the front and rear edge-wrapping units are connected by a feeding roller 19. The feeding roller 19 can be a feeding idler roller or a feeding upper and lower clamping roller, etc., which makes the connection and conveying between the two units smoother. Using the feeding upper and lower clamping roller to clamp the conveyor can also clamp the left and right edge-wrapping. The first edge-wrapping station 4 is located between the left and right edge-wrapping units and the front and rear edge-wrapping units. The rear edge-wrapping mechanism 40 is located between the left and right edge-wrapping units and the front and rear edge-wrapping units. The feeding roller 19 is located in the preceding position of the rear edge-wrapping mechanism 40.

[0037] In addition, in this embodiment, an edge-binding plate is used for edge binding, resulting in a tight edge binding and a relatively good edge binding effect, which can also meet some irregular edge binding requirements. For example, the rear edge binding mechanism 40 includes a first receiving edge binding support plate 41 and a first edge binding plate 42 for cooperating with the first receiving edge binding support plate 41 to complete the edge binding operation. The first receiving edge binding support plate 41 is configured at the feeding end of the conveyor belt 1. The first receiving edge binding support plate 41 is connected to the conveyor belt 1. The first receiving edge binding support plate 41 cooperates to receive and support the rear part of the material, and the first edge binding plate 42 cooperates to stabilize the edge binding; the front edge binding mechanism 50 includes a second receiving edge binding support plate 51 and a first edge binding plate 42 for cooperating with the first receiving edge binding support plate 41 to complete the edge binding operation. The second receiving edge-wrapping plate 51 completes the edge-wrapping operation. The second receiving edge-wrapping plate 52 is configured at the feeding output end of the conveyor belt 1 at the first guide shaft 31. The conveyor belt 1 is connected to the second receiving edge-wrapping plate 51. The second receiving edge-wrapping plate 51 supports and holds the front part of the material, and the second edge-wrapping plate 52 stabilizes the edge. The second receiving edge-wrapping plate 51 is located in the edge-wrapping operation clearance space 10. The second receiving edge-wrapping plate 51 is connected to the bracket 3.

[0038] The edge banding operation method is usually a mature technology, such as the lifting and forward / backward movement of the first edge banding plate 42 and the lifting and forward / backward movement of the second edge banding plate 52. The forward / backward movement can be horizontal or diagonal. The diagonal movement can create a diagonal pressing effect, which can make the edge banding tighter.

[0039] In addition, a first paper-pressing component (not shown in the figure) is provided above the first receiving and edge-sealing tray 41. The first paper-pressing component is driven by a first lifting and pressing paper-pressing drive component (such as a cylinder or motor). The first paper-pressing component is driven to lift and lower by the first lifting and pressing drive component. A second paper-pressing component (not shown in the figure) is provided above the second receiving and edge-sealing tray 51. The second paper-pressing component is driven by a second lifting and pressing paper-pressing drive component (such as a cylinder or motor). The second paper-pressing component is driven to lift and lower by the second lifting and pressing drive component. When the first and second paper-pressing components descend, they can press down the cardboard below. After the cardboard is in place, it is pressed down for subsequent edge-sealing to stabilize the edge-sealing operation and prevent the cardboard from shifting during the edge-sealing process. After the edge-sealing is completed, it rises back to its original position. Both the first receiving and edge-sealing tray 41 and the second receiving and edge-sealing tray 51 are arranged horizontally.

[0040] The second receiving and edge-sealing tray 51 is equipped with a lifting and positioning device 14 on its upper side to block the cardboard from moving forward. The lifting and positioning device 14 is connected to the lifting and positioning drive device 15 (such as a cylinder or motor). The lifting and positioning drive device 15 drives the lifting and positioning device 14 to move up and down. When it descends, it blocks the cardboard (with a face paper pasted on its lower surface) being moved forward by the conveyor belt 1. When it rises, it returns to its original position. The lifting and positioning device 14 can be a paper block. This allows the cardboard to be moved more accurately and stably by the conveyor belt 1, resulting in more precise edge sealing and higher edge sealing quality. Furthermore, the front and rear positions of the lifting and positioning device 14 can be adjusted to adjust the relative front and rear positions of the descending and blocking cardboard as needed, so as to adjust the material cardboard to the optimal position.

[0041] Further optimization involves using conveyor belt 1 as a single-piece material conveying and hemming processing station between the rear rotating shaft 21 and the first guide shaft 31. Conveyor belt 1 feeds intermittently, pausing when a single piece of material reaches its designated position on conveyor belt 1. The front and rear sides of the single piece of material can be hemmed simultaneously and in parallel. After completion, conveyor belt 1 continues feeding, outputting the material with the front and rear hemmed sides, allowing a new piece of material to be input. The structure is relatively compact, and the front and rear sides of the cardboard in the material can be hemmed simultaneously, which is not only efficient but also ensures relatively balanced and stable stress on the front and rear of the single piece of material.

[0042] In addition, the conveyor belt 1 is equipped with left and right cardboard positioning side gauges 13 above the area between the rear rotating shaft 21 and the first guide shaft 31, so that when the material enters the conveyor belt 1 and is conveyed, the left and right cardboard positioning side gauges 13 cooperate to position the cardboard so that the relative position of the cardboard is in the preset position, avoiding positional deviation that may affect the edge binding.

[0043] The first receiving and edge-wrapping support plate 41 can be equipped with a first corner-beating component 17, which is positioned on both sides for beveling the left and right ends before the rear edge-wrapping. Similarly, the second receiving and edge-wrapping support plate 51 can be equipped with a second corner-beating component 18, which is positioned on both sides for beveling the left and right ends before the front edge-wrapping. Both the first and second corner-beating components 17 and 18 are designed for lifting and moving left and right, and can be equipped with corresponding cylinders for lifting and moving left and right – a mature technology. For example, the corner-beating components of the first and second corner-beating components 17 and 18 can be corner-beating wheels. In this embodiment, a mounting base is provided for mounting the corner-beating components, and inner and outer wheels can be installed on the mounting base.

[0044] Two sets of longitudinally arranged (front-back) guide rods can be installed above the conveyor belt 1. Mounting seats for the corner-cutting components are mounted on the guide rod sets. A first cylinder is mounted on the mounting seat for left-right movement, and a second cylinder is connected to the first cylinder for lifting and lowering movement. The second cylinder is also connected to the corner-cutting component (such as the wheel seat of a corner-cutting wheel). The mounting seat can be moved back and forth on the guide rod sets to adjust its position to meet the corner-cutting requirements of materials of different lengths. The two sets of guide rods can also be moved closer together or apart to meet the corner-cutting requirements of materials of different widths. The two sets of guide rods can be mounted on the frame and moved closer or apart by a double-ended lead screw (or positive and negative lead screw). Additionally, cardboard positioning side gauges 13, which are separately positioned on the left and right, can also be correspondingly mounted on the two sets of guide rods. For example, the cardboard positioning side gauge 13 can be a side baffle, with a side gauge seat on the guide rod set for mounting the cardboard positioning side gauge 13. Furthermore, the cardboard positioning side gauge 13 can be additionally adjusted left and right on the side gauge seat, such as by adjusting it in the transverse groove of the side gauge seat and then fastening it.

[0045] For example, the first edge-binding plate 42 is installed on the first lifting seat 43. The first lifting seat 43 drives the first edge-binding plate 42 to move up and down. The first lifting seat 43 is installed on the first front-to-back moving frame 44, which moves back and forth. The first front-to-back moving frame 44 drives the first lifting seat 43 and the first edge-binding plate 42 to move back and forth together. At the edge-binding starting position, the first edge-binding plate 42 is flush with or lower than the first receiving edge-binding support plate 41. When the first edge-binding plate 42 rises, the face paper is folded upwards. Then, the first edge-binding plate 42 moves forward and folds the folded face paper forward to cover the cardboard for edge binding. After the edge binding is completed, it retracts and descends to reset, waiting for the next edge binding operation. The first lifting seat 43 moves up and down on the first front and rear moving frame 44. This movement is driven by a servo motor 45 on the first front and rear moving frame 44 via a lead screw and nut mechanism 46, etc. The first front and rear moving frame 44 can be mounted on a connecting fixing plate 47 (such as a machine frame). Another servo motor 48 is mounted on the connecting fixing plate 47 and, via a lead screw and nut mechanism or a connecting rod and eccentric wheel mechanism 49, drives the first front and rear moving frame 44 to move back and forth on the connecting fixing plate 47. The first edge-binding plate 42 is located above the first lifting seat 43. Before the edge-binding operation, the first front and rear moving frame 44 and the first lifting seat 43 are not higher than the first receiving edge-binding support plate 41. The first front and rear moving frame 44 is set to move horizontally back and forth or, when moving forward for edge-binding, to move diagonally from high to low.

[0046] The front edge-wrapping mechanism 50 also includes an edge-wrapping support frame 54, which is located above the second receiving edge-wrapping tray 51, forming an upper support structure. The edge-wrapping support frame 54 is equipped with a combined movable frame 53 that drives the second edge-wrapping plate 52 to rise, fall, and move forward and backward. The second edge-wrapping plate 52 is connected to the combined movable frame 53. The combined movable frame 53, in conjunction with the second edge-wrapping plate 52, drives its rise, fall, and forward and backward movement to complete the edge-wrapping operation. The combined movable frame 53 is supported by the upper edge-wrapping support seat, eliminating the need to occupy the lower bottom space, thus solving the problem of insufficient space at the bottom of the equipment and avoiding occupying too much bottom space, as well as the downward-recessed edge-wrapping operation clearance space 10 of the conveyor belt 1. The second edge-wrapping plate 52 has a waiting area and an edge-wrapping operation area, with the waiting area positioned above the edge-wrapping operation area. The second edge-sealing plate 52 descends to enter the edge-sealing operation area to cooperate with the second receiving edge-sealing tray 51 to perform the corresponding edge-sealing operation. That is, the second edge-sealing plate 52 moves down to the edge-sealing operation area to cooperate in performing the edge-sealing operation. After the second edge-sealing plate 52 completes the edge-sealing, it can rise to the preparation waiting area to wait for the next edge-sealing operation. The second edge-sealing plate 52 moves up to the preparation waiting area and then retreats to wait.

[0047] In the front edge-wrapping mechanism 50, the support of the second edge-wrapping plate 52 and the structure that drives its lifting and moving back and forth are all located at the top, without occupying too much space at the bottom. This solves the problem of insufficient space at the bottom of the equipment and the difficulty in configuring edge-wrapping plate support and running structure. It also avoids occupying too much bottom space and too much of the downward-recessed edge-wrapping operation clearance space 10 of the conveyor belt 1, making it convenient for the assembly and maintenance of the front edge-wrapping mechanism 50.

[0048] In this embodiment, the support for the second edge-sealing plate 52 and the structure that drives its lifting, lowering, and forward / backward movement are all located at the top, without occupying too much space in the downward recess. This not only reduces the size of the downward recessed opening of the conveyor belt 1, allowing materials to pass more smoothly over the edge-sealing operation clearance space 10 on the conveyor belt 1, but also avoids the problems of difficult assembly and maintenance caused by the support structure of the second edge-sealing plate 52 being located in the downward recess. The second receiving edge-sealing support plate 51 is arranged laterally in the edge-sealing operation clearance space 10.

[0049] The lifting paper stop positioning component 14 and the lifting paper stop driving component 15 are installed and connected on the edge-binding support frame 54. This not only facilitates assembly and has a compact structure, but also ensures that the lifting paper stop positioning component 14 and the second edge-binding plate 52 are in relatively uniform and well-matched relative positions on the edge-binding support frame 54, and can even be adjusted in position along with the edge-binding support frame 54. In addition, the edge-binding support frame 54 is also equipped with a paper stop adjustment mechanism 16 for adjusting the front and rear positions of the lifting paper stop positioning component 14 and the lifting paper stop driving component 15. The paper stop adjustment mechanism 16 adjusts the relative front and rear positions of the lifting paper stop positioning component 14, allowing the front and rear positions of the positioning cardboard to be adjusted as needed, and positioning the cardboard as required when blocking it.

[0050] For example, the combined movable frame 53 includes a second lifting seat 71 and a second front-to-back moving frame 72 that moves back and forth. The second lifting seat 71 and the second front-to-back moving frame 72 are connected in various ways. For instance, the edge-binding support frame 54 is provided with a first guide rail 73 that runs back and forth. The second front-to-back moving frame 72 is arranged on the first guide rail 73. The edge-binding support frame 54 is also provided with a first motor 74. The first motor 74 is connected to the second front-to-back moving frame 72 through a transmission. The first motor 74 drives the second front-to-back moving frame 72 to move back and forth on the edge-binding support frame 54. The second front-to-back moving frame 72 is provided with a vertically arranged second guide rail 75. The second lifting seat 71 is arranged on the second guide rail 75. The second front-to-back moving frame 72 is also provided with a second motor 76. The second motor 76 is connected to the second lifting seat 71 through a transmission. The second motor 76 drives the second lifting seat 71 to move up and down on the second front-to-back moving frame 72. The first guide rail 73 is horizontally arranged forward and backward; alternatively, the first guide rail 73 is inclined forward and backward, and the second edge-sealing plate 52 tilts and descends when it moves (e.g., backward, in the direction the cardboard enters) for edge sealing, resulting in a tighter edge seal. Both the first motor 74 and the second motor 76 are servo motors to facilitate adjustment and control of the lifting and forward / backward movement strokes, ensuring edge sealing effect and quality, and adapting to the edge sealing needs of different cardboard sizes. The first motor 74 is connected to the forward and backward moving frame via a first lead screw and nut mechanism 77, and the second motor 76 is connected to the lifting base via a second lead screw and nut mechanism 78. This mature technology ensures stable operation.

[0051] In the embodiment shown in the figure, the second edge-sealing plate 52 moves upward to the preparatory waiting area and then retreats to wait. The second edge-sealing plate 52 moves downward to the edge-sealing operation area to cooperate in performing the edge-sealing operation. The edge of the second receiving edge-sealing tray 51 has an edge-sealing starting position for the edge-sealing plate to descend into place. When the second edge-sealing plate 52 moves downward to the edge-sealing operation area, it can first descend to the edge-sealing starting position. The second edge-sealing plate 52 is flush with or lower than the second receiving edge-sealing tray 51 at the edge-sealing starting position. After the cardboard on the conveyor belt 1 arrives, the second edge-sealing plate 52 rises to fold the face paper upward. Then the second edge-sealing plate 52 moves forward (e.g., in the direction of the cardboard coming in from behind) to cover the cardboard with the folded face paper for edge sealing. After completion, the second edge-sealing plate 52 moves upward (rises) to the preparatory waiting area and retreats to wait. The relative position of the second edge-sealing plate 52 returns to the initial state for the next round of edge sealing.

[0052] For example, the edge-binding support frame 54 includes a suspended top plate 61, which is located above the second edge-binding support plate. The suspended top plate 61 is mounted above the second edge-binding support plate. Typically, the conveyor belt 1 is mounted on the frame, and a support plate can be added to the frame for the edge-binding support frame 54 to be installed. The first guide rail 73 is mounted on the suspended top plate 61 and is located on the lower side of the suspended top plate 61. The front and rear shifting frame includes a triangular seat, which includes an upper side plate 62 and a front vertical plate 63. A reinforcing plate 64 is also connected between the front vertical plate 63 and the upper side plate 62. The upper side plate 62 is connected to the first guide rail 73. The second guide rail 75 is mounted on the front vertical plate 63. The first motor 74 is mounted on the upper side of the suspended top plate 61, and the second motor 76 is mounted on the upper side plate 62. The suspended top plate 61 has a through hole for the second motor 76 to pass through. The second guide rail 75 is mounted on the front side of the front vertical plate 63, and the back side of the front vertical plate 63 is connected for the transmission of the second motor 76. The second edge plate 52 is mounted on the lower end of the lifting seat (such as the front vertical plate 63). The structure is compact.

[0053] For example, the frame includes side wall panels arranged on the left and right, and a longitudinal guide rail is provided on the frame for the support 3 to move back and forth. The support 3 is located between the front rotating shaft 22 and the rear rotating shaft 21. The support 3 includes support plates arranged on the left and right. The conveyor belt 1 is connected to an intermittent feeding drive device, which drives the conveyor belt 1 to run intermittently.

[0054] The bracket 3 can be adjusted forward and backward on the frame in several ways. For example, it can be adjusted using a rotating shaft 34. The frame has a longitudinally arranged rack 36, and the bracket 3 has a rotating shaft 34 arranged laterally. The rotating shaft 34 has a gear 35 that meshes with the rack 36. By rotating the rotating shaft 34, the gear 35 moves along the rack 36, thus moving the bracket 3. Alternatively, the rotating shaft 34 can be driven by an adjustment drive component 37, which drives the rotating shaft 34 to rotate. The adjustment drive component 37 is located on the bracket 3; the rack 36 is located inside the side wall plate, and the gear 35 is located above the rack 36. The adjustment drive component 37 includes an adjustment motor for electric operation; if a servo motor is used, the relative forward and backward position can be accurately adjusted.

[0055] The intermittent feeding drive device includes a feeding motor, which is connected to the conveyor belt 1 via a front rotating shaft 22 and / or a rear rotating shaft 21. The feeding motor can be a feeding servo motor, which can set the start and stop of the conveyor belt 1 and the conveying distance as required.

[0056] For example, the support plate is located inside the side wall panel, and the longitudinal guide rail is provided between the support plate and the side wall panel.

[0057] In addition, the frame is also equipped with a front auxiliary shaft 23 and a rear auxiliary shaft 24 for the conveyor belt 1 to be wound around. The front auxiliary shaft 23 is arranged below the front shaft 22, and the rear auxiliary shaft 24 is arranged below the rear shaft 21, which facilitates the overall winding of the conveyor belt 1. The installation height of the steering shaft 33 is higher than that of the front auxiliary shaft 23 and the rear auxiliary shaft 24. The structural layout is relatively reasonable, and the conveyor belt 1 between the front auxiliary shaft 23 and the rear auxiliary shaft 24 is relatively flat. The rear rotating shaft 21 and the front rotating shaft 22 are both horizontally oriented, and are mounted on the left and right side walls of the frame. Similarly, the front auxiliary rotating shaft 23 and the rear auxiliary rotating shaft 24 are also horizontally oriented, and are mounted on the left and right side walls of the frame. The first guide shaft 31, the second guide shaft 32, and the steering shaft 33 are all horizontally oriented, and are mounted on the left and right support plates of the bracket 3. These components work together to support and guide the conveyor belt 1, forming a closed loop.

[0058] The conveyor belt 1 is recessed downward between the first guide shaft 31 and the second guide shaft 32 and wound around the steering shaft 33. The recessed conveyor belt 1 forms the edge-wrapping operation avoidance space 10. In addition, the steering shaft 33 is distributed front and rear to form a structure with multiple (such as two) steering shafts 33 spreading out, and the bottom of the edge-wrapping operation avoidance space 10 is relatively larger.

[0059] The conveyor belt 1 is closed and looped in a circle. The first feeding area 11 is located between the rear rotating shaft 21 and the first guide shaft 31, and is configured for lateral feeding. The second feeding area 12 is located between the second guide shaft 32 and the front rotating shaft 22. An edge-sealing operation clearance space 10 is located between the first and second feeding areas 11 and 12, connecting them. During material transport, the material on the first feeding area 11 passes through the upper side of the edge-sealing operation clearance space 10 and enters the second feeding area 12 for transport. The upper side of the edge-sealing operation clearance space 10 forms the material passage path. The second feeding area 12 is configured for lateral feeding, resulting in relatively stable feeding and smoother connection between the front and rear feeding sections. The rear rotating shaft 21, the first guide shaft 31, the second guide shaft 32, and the front rotating shaft 22 are aligned from front to back at the top.

[0060] In addition, an auxiliary material handling component (not shown in the figure) is provided at the edge-wrapping operation clearance space 10. The auxiliary material handling component can assist the auxiliary material to smoothly enter from the first feeding area 11 to the second feeding area 12. The auxiliary material handling component is installed on the bracket 3 to ensure that it can still assist the material to pass smoothly after the front and rear positions of the bracket 3 are adjusted. The auxiliary material handling component is located between the first guide shaft 31 and the second guide shaft 32. In addition, the auxiliary material handling component is raised and lowered on the bracket 3. The auxiliary material handling component is driven by a lifting material support drive component (such as a cylinder or motor) to raise and lower on the bracket 3. When the auxiliary material handling component rises to a high position, it connects with the feeding path of the conveyor belt 1. The rise of the auxiliary material handling component assists the material to pass smoothly from the first feeding area 11 to the second feeding area 12. When the auxiliary material handling component descends, it frees up more space in the edge-wrapping operation clearance space 10 for the second edge-wrapping plate 52 in the embodiment shown in the figure to descend to the edge-wrapping operation area. The auxiliary material handling component is connected to the bracket 3 through the lifting material support drive component. For example, auxiliary material handling components may use material handling plates, material handling rollers, or material handling shafts.
