Description

TECHNICAL FIELD

[0001] The utility model relates to the corresponding edge covering mechanism of leather case machine. BACKGROUND

[0002] The leather case is formed by pasting paperboard and surface paper, which can be used for paper box, wine package leather case, cigarette package leather case, notebook, file folder, hanging calendar, desk calendar, book cover, etc.

[0003] The paperboard and surface paper are positioned and attached in the cover mechanism (also known as cover machine, positioning machine, positioning and pasting device) to form a material, and the material is sent to the edge covering mechanism for additional edge covering operation, i.e. the surface paper on the lower side of the paperboard is also folded and covered on the side edge of the paperboard to form an edge covering structure, such as edge covering on the front and back edges and left and right edges of the paperboard.

[0004] The edge covering mechanism in the leather case machine includes a first edge covering device and a second edge covering device, which respectively perform corresponding front and back edge covering and left and right edge covering on the paperboard. Among them, the material needs to be sent to the edge covering mechanism in turn through the first edge covering device and the second edge covering device to complete the respective edge covering. How to efficiently operate the edge covering mechanism is crucial, which can improve efficiency, process more objects in the same time unit, complete more leather case production, and help reduce production cost.

[0005] The first edge covering device and the second edge covering device respectively perform corresponding front and back edge covering (i.e. first edge covering) and left and right edge covering (i.e. second edge covering) on the paperboard. After the first edge covering, the second edge covering is performed again. After the first edge covering, the surface paper is covered on the paperboard. Since the paperboard has a certain thickness, the paperboard and the surface paper will have hollowing at both ends of the edge covering after edge covering. If the second edge covering is performed directly, it will cause the existence of hollowing, and the angle area between the front and back edge covering and the left and right edge covering will cause problems such as not tight edge covering due to the existence of hollowing.

[0006] In addition, the front and back edges of the paperboard have different widths and specifications, and the edge covering and corner punching (also known as corner pinching) need to match the specifications of the paperboard. UTILITY MODEL CONTENTS

The material pressing and clamping swing arm is provided with a material pressing part for clamping the material in cooperation with the material supporting component. The material supporting component is arranged on the lifting seat and outside the longitudinal feeding belt. The material supporting component has a raised high position state and a lowered low position state. In the raised high position state, the material supporting surface of the material supporting component is lower than or flush with the material supporting surface of the longitudinal moving material supporting plate. In the lowered low position state, the material supporting surface of the material supporting component is lower than or flush with the feeding surface of the longitudinal feeding belt. The material pressing and clamping swing arm is drivenly connected to a reciprocating swing driving component. The reciprocating swing driving component is arranged on the lifting seat. The material pressing part is a material pressing roller. The material supporting component comprises a sponge pad.

[0018] The beneficial effects of the utility model are that when the material is put into the first edge covering device downward, the front and rear first edge covering plates can directly lift the paper parts to be edge covered on the front and rear of the material upward, and then the first edge covering device can complete the edge covering of the material (front and rear edges) by moving the front and rear first edge covering plates (toward the middle direction) longitudinally, and the first edge covering plate and the longitudinal moving supporting plate in the first edge covering device are both moved in the corresponding longitudinal linear direction, which is simpler, more stable and more efficient. When the material is put into the first edge covering device downward, the paper edge limiting stopper can block and limit the front and rear edges of the material to ensure that the position of the material will not deviate, and the position of the material is relatively accurate, which is beneficial to the subsequent edge covering and corner pinching (corner punching) processing, and the position of the material will not deviate in the subsequent operation (such as the subsequent moving edge covering process of the first edge covering plate).

[0019] In addition, after optimization, the structure of the edge covering mechanism of the skin machine is more efficient.

The first edge covering device is not affected by the material from above, and the efficiency is higher, the speed is relatively faster, and the processing quantity is larger in the same time. In addition, when the material is put into the first edge covering device downward, the front and rear first edge covering plates can directly lift the paper parts to be edge covered on the front and rear of the material upward, and then the first edge covering device can complete the edge covering of the material (front and rear edges) by moving the front and rear first edge covering plates (toward the middle direction) longitudinally, and the first edge covering plate and the longitudinal moving supporting plate in the first edge covering device are both moved in the corresponding longitudinal linear direction, which is simpler, more stable and more efficient. In the material feeding and final output process, the material does not need to be withdrawn, the material conveying is more efficient, which helps to improve the efficiency and the whole edge covering speed.

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0040] Referring to the drawings, the skin machine in the embodiments of the present embodiment includes a face paper feeding and lifting platform 10, a face paper feeding device 11, a face paper gluing device 12, a suction conveying belt 13, a paperboard and face paper positioning and pasting device 14, and a edge covering mechanism 15. The face paper feeding and lifting platform 10 is connected with the face paper gluing device 12 through the face paper feeding device 11. The face paper feeding device 11 cooperates to feed the face paper into the face paper gluing device 12. The output end of the face paper gluing device 12 is connected with the suction conveying belt 13. The face paper is output to the suction conveying belt 13 after being glued in the face paper gluing device 12. The paperboard and face paper positioning and pasting device 14 and the edge covering mechanism 15 are arranged on one side of the suction conveying belt 13. The face paper is carried by the suction conveying belt 13 and moved to the paperboard and face paper positioning and pasting device 14. The paperboard and face paper positioning and pasting device 14 cooperates to place the paperboard on the face paper to form a skin material. Then, the material is continuously conveyed by the suction conveying belt 13 to the edge covering mechanism 15. The edge covering mechanism 15 is connected with the suction conveying belt 13 through the feeding and lifting transfer mechanical hand 16. The feeding and lifting transfer mechanical hand 16 cooperates to feed the material on the suction conveying belt 13 into the edge covering mechanism 15. The face paper feeding device 11 adopts a flying head paper feeder. The face paper gluing device 12 includes a gluing roller. The paperboard and face paper positioning and pasting device 14 includes a paperboard cover mechanism. This is mature technology and will not be described again.

[0041] In the present embodiment, in order to relatively accurately position the material, complete the corner pinching process, and improve the speed and efficiency, the edge covering mechanism 15 (i.e., the edge covering mechanism 15 of the skin machine) is optimized and improved.

[0042] The edge covering mechanism 15 of the leather case machine comprises a first edge covering device 3 and a second edge covering device 4, the first edge covering device 3 is used for covering the front and back edges of the material (such as long edge covering), and the second edge covering device 4 is used for covering the left and right edges of the material (such as short edge covering); the first edge covering device 3 and the second edge covering device 4 are provided with a longitudinal feeding belt 5, and the first edge covering device 3 is moved to the second edge covering device 4 for subsequent (left and right edge) covering by cooperation of the longitudinal feeding belt 5; the first edge covering device 3 comprises a first edge covering plate 31 and a longitudinal moving supporting plate 32, the first edge covering plate 31 is arranged in pairs in front and back, and the longitudinal moving supporting plate 32 is arranged in pairs in front and back, that is, the first edge covering plate 31 in front and back and the longitudinal moving supporting plate 32 in front and back are opposite to each other, the first edge covering plate 31 in front and back is used for cooperating with covering the front and back edges of the material (such as long edge covering), the first edge covering plate 31 is arranged on the upper side of the corresponding longitudinal moving supporting plate 32, the first edge covering plate 31 is a longitudinal moving edge covering plate, that is, the first edge covering plate 31 is longitudinally moved on the upper side of the corresponding longitudinal moving supporting plate 32, and the longitudinal moving supporting plate 32 can also be longitudinally moved;

[0043] The first edge covering plate 31 and the longitudinal moving supporting plate 32 below are left with a material containing space matching the thickness of the material, so that when the material (including the paper and the paperboard) is placed on the longitudinal moving supporting plate 32, the first edge covering plate 31 can be smoothly longitudinally moved above the material to fold the paper and cooperate with the covering; the first edge covering plates 31 in front and back are separated from each other to form a working position for upwardly tilting the paper, and the first edge covering plates 31 in front and back are moved into a space below each other, in this position, the material is placed downward in the space below each other, and the longitudinal moving supporting plates 32 in front and back can be cooperatively operated at the front and back edges below the space, when the material (the paperboard with the paper on the lower side) is placed downward, the first edge covering plates 31 in front and back can tilt the paper on the paperboard edge upward in this position;

[0044] The longitudinal moving supporting plates 32 in front and back are moved toward each other to form a working position for supporting the material, when the material is placed downward in the space below each other, the longitudinal moving supporting plates 32 in front and back can cooperatively support the material in this position, and the material (including the paper and the paperboard) is placed on the longitudinal moving supporting plates 32, so as to be subjected to subsequent covering operation; the longitudinal moving supporting plates 32 in front and back are separated from each other to form a working position for discharging the material, in this position, the longitudinal moving supporting plates 32 in front and back are in a separated state, and can release (support) the material to move downward;

[0045] The longitudinal feeding belt 5 is arranged below the longitudinal moving supporting plate 32. When the front and rear longitudinal moving supporting plates 32 are in the state of being separated from each other, the material can be moved downward to the longitudinal feeding belt 5, and then the material is sent to the second edge covering device 4 by the longitudinal feeding belt 5 for edge covering and directly output after the edge covering is completed. The downward feeding device 6 is arranged between the longitudinal feeding belt 5 and the longitudinal moving supporting plate 32. The material is stably and accurately moved downward to the longitudinal feeding belt 5 by the downward feeding device 6, so as to avoid the problems of unstable position and the like. The downward feeding device 6 moves the material from the first edge covering device 3 to the second edge covering device 4 in cooperation with the longitudinal feeding belt 5.

[0046] The second edge covering device 4 comprises the second edge covering plates 41 arranged in pairs on the left and right sides. The second edge covering plates 41 arranged in pairs on the left and right sides are used for covering the left and right edges of the material (for example, the short edge covering). The second edge covering plates 41 are arranged on the outside of the longitudinal feeding belt 5, and the left and right middle positions are the inside, and the left and right side positions are the outside. For example, the left second edge covering plate 41 is arranged at the left side position of the longitudinal feeding belt 5, and the right second edge covering plate 41 is arranged at the right side position of the longitudinal feeding belt 5.

[0047] The paper edge limiting block 7 is arranged between the first edge covering plates 31 and the corresponding longitudinal moving supporting plates 32 below. The paper edge limiting block 7 is arranged between the first edge covering plates 31 and the corresponding longitudinal moving supporting plates 32 below to form the paper edge blocking and limiting structure on the front and rear sides. The paper edge limiting block 7 is used for limiting and blocking the (front and rear) edges of the material. After the material is placed, the material is supported by the front and rear longitudinal moving supporting plates 32, and the (front and rear) edges of the material are limited and blocked by the paper edge limiting block 7. The position of the material is relatively accurate, which is beneficial to subsequent edge covering and corner pinching (corner punching) processing, and the position of the material will not deviate in the subsequent operation (for example, the subsequent moving and edge covering process of the first edge covering plate). In addition, the longitudinal moving corner pinching component 8 is arranged between the first edge covering plates 31 and the corresponding longitudinal moving supporting plates 32 below. The longitudinal moving corner pinching component 8 is arranged between the first edge covering plates 31 and the corresponding longitudinal moving supporting plates 32 below to form the corresponding longitudinal moving corner pinching component 8. The longitudinal moving corner pinching component 8 can move longitudinally (in the same direction as the forward and backward edge covering reciprocating movement of the first edge covering plate 31). The longitudinal moving corner pinching component 8 is used for cooperating with the corner pinching and corner punching operation, and can press the hollow drums at the corners of the two sides of the material (after the material is covered by the first edge covering plate 31) to the ground. The second edge covering is relatively more compact. The paper edge limiting block 7 is arranged between the longitudinal moving corner pinching components 8 arranged on the left and right sides. The blocking and limiting function of the paper edge limiting block 7 will not interfere with the normal operation of the longitudinal moving corner pinching component 8, and the blocking and limiting function of the paper edge limiting block 7 is ensured.

[0048] Wherein, when the material is put down into the first edge covering device, the first edge covering plate 31 can directly lift the paper part of the material to be edge covered up, and then the first edge covering plate 31 only needs to move longitudinally to complete the edge covering of the material.

[0049] The working principle is that the paper is fed into the glue feeding device in the skin machine, and then the paper is carried by the suction conveying belt 13 and positioned with the paperboard to form a skin material after the glue feeding is completed. Then the skin material on the suction conveying belt 13 is lifted by the feeding and lifting transfer manipulator 16, and then is transferred to the first edge covering device 3 after being lowered. This is a mature technology and will not be described in detail.

[0050] The working principle of the edge covering mechanism 15 of the skin machine is that the material put into the lower material space is lifted up by the first edge covering plate 31, and the first edge covering plate 31 does not need to be operated additionally. When the material is put into position, the front and rear longitudinal material supporting plates 32 are closed to support the material on the upper side, and the paper edge limiting block limits and blocks the edge of the material. Then, the front and rear first edge covering plates 31 are closed to each other to fold the paper part that has been lifted up to the middle of the front and rear, complete the edge covering of the front and rear, and the front and rear first edge covering plates 31 can be separated and returned to wait for the next feeding. Then, the front and rear longitudinal material supporting plates 32 are separated to release the material, and the material can be lowered. At this time, the new material to be edge covered can be put into the lower material space, which is relatively more efficient. The front and rear longitudinal material supporting plates 32 are in a separated state to release the material, so that the material can be lowered by the lower feeding device 6 to be accurately fed to the longitudinal feeding belt 5, and then the material is transferred from the first edge covering device 3 to the second edge covering device 4.

[0051] The structure of the edge covering mechanism 15 of the leather case machine is optimized, so that the edge covering mechanism 15 of the leather case machine is more efficient. After the material is covered by the first edge covering device 3 (front and back edges), the material will be directly conveyed downward to the longitudinal feeding belt 5, and then moved to the second edge covering device 4 for cooperation to complete the covering of the left and right edges. This does not affect the feeding of the first edge covering device 3 from above, and the efficiency is higher and the speed is relatively faster. Moreover, when the material is placed downward into the first edge covering device 3, the front and back edge covering plates 31 can directly lift the front and back edge covering parts of the material upward, and then only the front and back edge covering plates 31 need to be moved longitudinally (toward the middle) to complete the edge covering of the material (front and back edges). The first edge covering plate 31 and the longitudinal moving supporting plate 32 in the first edge covering device 3 are both moved longitudinally, which is simpler, more stable and more efficient. During the feeding and final output of the material, the material does not need to be withdrawn, the material conveying is more efficient, which helps to improve the efficiency and the overall edge covering speed. In the same time unit, more objects can be processed, more leather cases can be made, and the production cost can be reduced.

[0052] The following optimizations or further explanations can be made based on the above embodiments.

[0053] For example, the downward feeding space is configured with a feeding lifting and transferring manipulator 16, which cooperates with the feeding lifting and transferring manipulator 16 to place the material into the downward feeding space. For example, the feeding lifting and transferring manipulator 16 includes a lifting suction nozzle 17, which cooperates with the lifting suction nozzle 17 to suck the material, lift it, transfer it, and then release it after it is lowered. There are many ways to do this, and it is relatively mature. Industrial robots can be used for cooperation. The feeding lifting and transferring manipulator 16 can also move together with a pressing block 18, which can press the material to make it more stable and flat when placed on the longitudinal moving supporting plate 32. Corresponding lifting suction nozzles 17 and pressing blocks 18 are arranged on the transfer frame of the feeding lifting and transferring manipulator 16.

[0054] The longitudinal moving operation of the longitudinal moving corner component 8 can be driven by a single power source (such as a motor or a pneumatic cylinder, etc.). Alternatively, the longitudinal moving corner component 8 can be directly connected to the first edge covering plate 31, and the longitudinal moving corner component 8 can be retracted relative to the first edge covering plate 31. The longitudinal moving corner component 8 can move longitudinally together with the first edge covering plate 31 (i.e., it can share the power drive to move longitudinally). During operation, the first edge covering plate 31 completes the edge covering and folding first, and then the longitudinal moving corner component 8 cooperates with the corner to complete the operation. Compared with the multiple power drive mode, the operation is more convenient and simple.

[0055] The first edge covering plate 31 can be replaced with different sizes to meet the material size requirements or edge covering shape requirements. In addition, the frame of the edge covering mechanism 15 is provided with a front support 35 and a rear support 36. The front support 35 and the rear support 36 can be flat plates. The first edge covering plate 31 and the longitudinal material supporting plate 32 are arranged on the front support 35 and the rear support 36, respectively. The front and rear first edge covering plates 31 are arranged on the front support 35 and the rear support 36, respectively. The front and rear longitudinal material supporting plates 32 are arranged on the front support 35 and the rear support 36, respectively. The rear support 36 is provided with a support longitudinal position adjusting device 37 between the rear support 36 and the frame. The rear support 36 is adjusted in the longitudinal relative position on the frame by the support longitudinal position adjusting device 37 (such as longitudinal guide rail), so that the distance between the rear support 36 and the front support 35 is adjusted, the distance between the front and rear first edge covering plates 31 is adjusted, the distance between the front and rear longitudinal material supporting plates 32 is adjusted, and different material size requirements are met. The front support 35 and the rear support 36 are respectively provided with an edge covering longitudinal driving component 38 and a material supporting longitudinal driving component 39. The first edge covering plate 31 is driven forward and backward by the edge covering longitudinal driving component 38. The edge covering longitudinal driving component 38 can be a cylinder or a motor (such as a servo motor). For example, the edge covering longitudinal driving component 38 includes a motor 380 (such as a servo motor) driving a main shaft 381 to rotate back and forth. An eccentric wheel 382 is arranged on the main shaft. The eccentric wheel drives the first edge covering plate 31 to move forward and backward by a connecting rod 383. The connecting rod is hinged at both ends of the eccentric wheel and the first edge covering plate 31. The relative efficiency is higher. The distance of the edge covering longitudinal movement can be adjusted by the rotation angle range of the main shaft, which is more convenient. The material supporting longitudinal driving component 39 drives the longitudinal material supporting plate 32 to move forward and backward. The material supporting longitudinal driving component 39 can be a cylinder or a motor (such as a servo motor). For example, a cylinder is used in the figure.

[0056] In addition, the paper edge limiting stoppers 7 are arranged on the left and right between the first wrapping plate 31 and the corresponding longitudinal shifting material supporting plate 32 below, that is, the front and rear edges of the material each have two paper edge limiting stoppers 7 arranged on the left and right to block and limit, the blocking and limiting effect is relatively good and stable, and after being arranged on the left and right, the left and right spacing between the paper edge limiting stoppers 7 can be adjusted to meet the width requirements of different materials, and the paper edge limiting stoppers 7 are arranged on the fixed seat 70, that is, the relative position of the paper edge limiting stoppers 7 is in a fixed state during the entire wrapping operation, which is more stable; for example, after being arranged on the left and right, the paper edge limiting stoppers 7 are arranged on the left and right positions of the fixed seat 70, and the left and right position adjustment arrangement is various, and a structure in which a fastener is tightened on a horizontal sliding groove (track) of the fixed seat 70 is used. The fixed seat 70 is arranged on the corresponding front support 35 and rear support 36; the longitudinal shifting corner pinching component 8 is arranged on the left and right positions of the first wrapping plate 31, and the left and right position adjustment can make the longitudinal shifting corner pinching component 8 meet the width requirements of different materials; for example, the longitudinal shifting corner pinching component 8 is installed and arranged on the longitudinal shifting sliding seat 33, forming a structure in which the longitudinal shifting corner pinching component 8 and the first wrapping plate 31 are connected and longitudinally shifted together, and the longitudinal shifting sliding plate 33 drives them to longitudinally shift together; for another example, the longitudinal shifting corner pinching component 8 is arranged on the left and right positions of the longitudinal shifting sliding seat 33, and the left and right position adjustment arrangement is various, and a structure in which a fastener is tightened on a horizontal sliding groove (track) of the longitudinal shifting sliding seat is used.

[0057] The longitudinal shifting corner pinching component 8 can adopt a corner pinching sheet, wherein the corner pinching sheet has a corner pinching part 80; the corner pinching part 80 cooperates with the corner pinching and corner punching to press the corner positions of the left and right outer sides of the paperboard of the material (front and rear edges); the corner pinching starting end of the corner pinching part 80 is arranged upward, and the corner pinching starting end first contacts the material to start corner pinching when longitudinally shifting, and the upward arrangement makes it easier to press the material downward for corner pinching. The corner pinching sheet can be made of a metal material (for example, a stainless steel spring sheet or an iron spring sheet), has elasticity, is convenient for stamping, and has a relatively long service life. The corner pinching sheet can further have an auxiliary part 81, the corner pinching sheet has a gap between the auxiliary part 81 and the corner pinching part 80, the auxiliary part 81 is located outside the corner pinching part 80, and the corner pinching part 80 is recessed compared with the auxiliary part 81, the position of the auxiliary part 81 is relatively more prominent, the auxiliary part 81 can play an indicating and indicating role, avoid the problem that the corner pinching part 80 is not easy to observe after being blocked by the first wrapping plate, and make it not easy to observe when adjusting the relative position, which makes debugging more convenient, and the auxiliary part 81 can even play a role in auxiliary support on the longitudinal shifting material supporting plate.

[0058] For example, the downward feeding device 6 comprises a lifting seat 60, a material supporting component 61 and a material pressing and placing swing arm 62, the material pressing and placing swing arm 62 is hinged on the lifting seat 60 (the hinge shaft 67 can be longitudinally arranged front and back to form a swing rotating support structure), the material pressing and placing swing arm 62 can swing on the lifting seat 60, the material supporting component 61 is arranged on the lifting seat 60, and the material supporting component 61 is used for supporting and carrying the material, they (the material pressing and placing swing arm 62 and the material supporting component 61) can be lifted and lowered together with the lifting seat 60, wherein the lifting of the lifting seat 60 can be driven by the lifting transmission structure 66, such as a cylinder or a driving shaft with a gear and rack 69 transmission, and a vertical guide rail 68 can be arranged for stable lifting action of the lifting seat 60; wherein the material pressing and placing swing arm 62 is arranged outside the longitudinal feeding belt 5, and the material supporting component 61 is arranged outside the longitudinal feeding belt 5 to avoid interfering with feeding, the left and right middle positions are inside, and the left and right sides are outside (consistent below), for example, the left material pressing and placing swing arm 62 and the left material supporting component 61 are located at the left side of the longitudinal feeding belt 5, and the right material pressing and placing swing arm 62 and the right material supporting component 61 are located at the right side of the longitudinal feeding belt 5. The material pressing and placing swing arm 62 is provided with a material pressing part 63, which swings and lifts with the material pressing and placing swing arm 62 on the lifting seat 60, so that the material pressing part 63 cooperates with the material supporting component 61 to clamp and place the material; for example, when the material pressing and placing swing arm 62 swings downward toward the material supporting component 61, the material pressing part 63 will press on the material supporting component 61 to clamp the material, and after clamping the material, the lifting seat 60 can be lowered to cooperate with the downward feeding; when the front and back longitudinal material supporting plates 32 are separated from each other, the downward feeding device 6 (such as the material pressing part 63) cooperates with the clamped material to feed downward to the longitudinal feeding belt 5; for another example, when the material pressing and placing swing arm 62 swings upward away from the material supporting component 61, the material pressing part 63 is separated from the material supporting component 61 to release the material, and after the downward feeding device 6 (such as the material pressing part 63) cooperates with the clamped material to feed downward to the longitudinal feeding belt 5, the downward feeding device 6 (such as the material pressing part 63) can release the material, and then the lifting seat 60 is raised again to wait for the next work (downward feeding). Wherein the material supporting component 61 has an upper high position state and a lower low position state, that is, the material supporting component moves up and down with the lifting seat 60 to form a high and low position state; in the upper high position state, the material supporting surface of the material supporting component 61 is lower than or flush with the material supporting surface of the longitudinal material supporting plate 32 to ensure stable transition of the material; in the lower low position state, the material supporting surface of the material supporting component 61 is lower than or flush with the feeding surface of the longitudinal feeding belt 5 to ensure stable placement of the material on the longitudinal feeding belt 5.

[0059] The pressure material clamp swing arm 62 is driven by a reciprocating swing driving part 64 (such as a cylinder or a motor, a cylinder is connected between the pressure material clamp swing arm 62 and the lifting seat 60, and the cylinder piston rod 641 is hinged at one end of the pressure material clamp swing arm 62). The reciprocating swing driving part 64 is arranged on the lifting seat 60, and the pressure material clamp swing arm 62 is driven by the reciprocating swing driving part 64 to swing on the lifting seat 60. For example, the pressure material part 63 is optimized to use a pressure material roller, and the material supporting part 61 includes a sponge pad, which can stably clamp the material without damaging it. After the material falls on the longitudinal feeding belt 5, it can be directly dragged to move longitudinally without the need to wait for the pressure material clamp swing arm 62 to reset and swing to separate the pressure material part 63 from the material supporting part 61, which is faster and convenient for speedup. In addition, the pressure material clamp swing arm 62 is also provided with a feeding auxiliary pressure wheel 65 located at the side of the pressure material part 63. The feeding auxiliary pressure wheel 65 rises and swings with the pressure material clamp swing arm 62, and can cooperate with the downward feeding to press the material on the longitudinal feeding belt 5 by the feeding auxiliary pressure wheel 65. After the feeding auxiliary pressure wheel 65 is lowered, the material is pressed on the longitudinal feeding belt 5 to ensure stable longitudinal movement and transportation of the material, avoiding position deviation and slipping during the longitudinal movement and transportation of the material, and not interfering with the normal operation of the downward feeding device 6.

[0060] In addition, the outer side of the longitudinal feeding belt 5 is also provided with a pre-edge folding material upwarp guiding part 51, for example, the pre-edge folding material upwarp guiding part 51 includes a pre-edge folding material upwarp guiding plate or a guiding rod. During the cooperation of the longitudinal feeding belt 5 with the material moving forward, the face paper on the left and right sides of the material can be pre-upwarped by the pre-edge folding material upwarp guiding part 51, which makes the subsequent left and right edge folding more smooth, efficient and effective.

[0061] In order to facilitate installation and position adjustment, the left support 53 and the right support 54 on the rack are provided with corresponding second edge folding plates 41 and longitudinal feeding belts 5.

As shown in the figure, the lifting driving device 45 includes a servo motor with a screw rod and a nut transmission structure (including a screw rod 402) to drive the lifting frame 43 to move up and down. The lifting height and stroke of the lifting frame 43 are easily adjustable, and the lifting height and stroke of the second edge covering plate 41 are adjustable and more accurate, which can make the edge covering more secure. A turnover shaft 46 is further arranged on the lifting frame 43, and the turnover shaft 46 is provided with a turnover driving device 47 (such as a motor or an air cylinder).
