Description

TECHNICAL FIELD

[0001] The utility model relates to a frame making, especially a frame paper box making and forming equipment. BACKGROUND

[0002] For example, wine boxes, drawer boxes, book boxes, and top and bottom cover boxes, the box body is a closed frame structure, such as a square frame. When making this kind of frame, the material (including paperboard and surface paper) is held on the upper (horizontal) mold, and then the final connection (such as lap joint, i.e., upper side forming) is performed on the upper side of the (horizontal) mold to realize closure and form the frame. For example, the closure forming structure on the closure mold in CN104842588A paper box forming machine side forming mechanism, CN218286882U paper box forming equipment production line, CN216330403U paper box forming holding mechanism, CN219968976U frame forming mechanism, etc. Among them, the lower side of the paperboard in the material (corresponding to the outside of the box body) is pasted with surface paper, and the upper side of the paperboard (corresponding to the inside of the box body) is usually slotted to facilitate folding and closing. The paperboard forms a plurality of regions of multi-ply paperboard, and the surface paper also has a plurality of regions corresponding to the paperboard, and the surface paper is on the outside of the box body after closure. For example, the paperboard has four regions (i.e., four-ply paperboard) corresponding to the square frame box body (corresponding to the four side walls of the frame box body), and the surface paper also has four regions corresponding to the paperboard and pasted on the lower side of the paperboard with one region offset. For example, the right three regions of the paperboard are pasted with the left three regions of the surface paper, and the leftmost region of the paperboard is not pasted, and the rightmost region of the surface paper is not pasted. When closing, the surface paper of the rightmost region can be pasted on the outside of the leftmost region of the paperboard, and the pasting is completed. This material closure of the paperboard and the surface paper with one region offset is a mature technology for forming a frame box body, but for relatively narrow and long strip materials, the strip material (strip-shaped paperboard and surface paper) is unstable during the final closure. The surface paper of the rightmost region is not pasted and is prone to instability during the folding and closing process due to its narrowness, length, and softness. The surface paper is not easy to fold into place and may be skewed, and the surface paper of the rightmost region needs to be pasted from the right to the left (and reset after pasting) during the folding and closing process to be completely pasted on the paperboard. For materials with a relatively long size, the pasting efficiency is low. SUMMARY

DETAILED DESCRIPTION

[0040] Referring to the drawings, the box body face paper feeding device 71, the box body face paper gluing device 72, the material conveying device 57, the material pasting station 58, the three-port edge covering station 60, and the frame box forming main machine 73 are connected in sequence. The box body face paper feeding device 71 is connected with the box body face paper gluing device 72 through the paper feeding device 74. The output end of the box body face paper gluing device 72 is connected with the material conveying device 57. The material pasting station 58 is connected with the material pasting device 59 for pasting the face paper of the box body paperboard. The three-port edge covering station 60 is connected with the three-port face paper edge covering device 61 for covering the left and right lower three sides of the horizontal frame box body. The material conveying device 57 is connected between the material pasting station 58 and the three-port edge covering station 60, and between the three-port edge covering station 60 and the second mold resting position 2. The material conveying device 57 moves the glued face paper to the material pasting station 58 (the paperboard is pasted on the face paper), then continues to move the face paper and the pasted paperboard to the three-port edge covering station 60 (for three-port edge covering), and then continues to send the material into the frame box forming main machine 73. In addition, a material deviation correcting and pressing station 76 can be arranged between the material pasting station 58 and the three-port edge covering station 60 (to make the pasting more firm). Even a magnet loading station can be arranged between the face paper gluing device and the material pasting station 58. A corresponding magnet piece assembling device 75, such as the magnet piece or metal piece assembling device of the leather shell production equipment CN219504085U, is arranged to directly load a magnetic piece on the glued face paper, so that the frame box has a magnetic attraction function. Even an oven station can be arranged between the face paper gluing device and the material pasting station 58. The glued face paper is conveyed by the material conveying device 57 and passes through the oven to make the glue work quickly. For example, the paper box forming equipment production line CN218286882U, the novel paper box forming production line CN216330338U, the paper box forming production line CN113650351A, and the paper box forming production line CN215243189U are mature technologies. The box body face paper feeding device 71 includes a lifting paper feeding table 33. The paper feeding device 74 includes a flying paper feeder. The box body face paper gluing device 72 includes a gluing roller. The cover pasting device includes a cover mechanical hand. The three-port edge covering device for the flat paperboard includes an edge covering plate. The material conveying device 57 includes a material conveying belt 62 and a material input mechanical hand 63. The material conveying belt 62 connects the material pasting station 58 and the three-port edge covering station 60. The material input mechanical hand 63 is connected between the material conveying belt 62 and the second mold resting position 2. The demolding and box body conveying device 40 is further connected with a paper box bubble pressing machine. Even a box cover assembling machine, an inner support assembling machine, a panel assembling machine, and the like can be connected in sequence according to requirements.The frame paper box forming main machine 73 adopts the following structure in the embodiment.

[0041] The frame paper box forming main machine 73 in the embodiment includes a four-station mold rotating device, which includes a box body horizontal forming mold 100 (four can be provided) that intermittently rotates and stays around a vertical center axis. The box body of the frame paper box is formed by a frame box body 200 and a box bottom plate 800 combined and connected, and is formed and manufactured in cooperation with the box body horizontal forming mold 100. The box body horizontal forming mold 100 is combined and connected by a plurality of mold plates according to requirements. The outer end surface 1001 (i.e., the front surface) of the rotating circumference of the box body horizontal forming mold 100 outward in the radial direction is provided with a box bottom plate air suction and discharge nozzle 1002. The box body horizontal forming mold 100 has a first mold staying position 1, a second mold staying position 2, a third mold staying position 3, and a fourth mold staying position 4, that is, the box body horizontal forming mold 100 intermittently rotates and stays around the vertical center axis, and stays at the first mold staying position 1, the second mold staying position 2, the third mold staying position 3, and the fourth mold staying position 4 in turn.

[0042] The first mold staying position 1 is provided with a box bottom plate assembly device 10 on the outer end surface 1001 of the mold, and the box bottom plate assembly device 10 is used to assemble the box bottom plate on the outer end surface 1001 of the box body horizontal forming mold 100 staying at the first mold staying position 1, which can be sucked by the box bottom plate air suction and discharge nozzle 1002. The box bottom plate assembly device 10 has various structures and is relatively mature, such as the related bottom structures in CN218286882U paper box forming equipment production line, CN104842586A paper box forming machine, etc.

[0043] The second mold staying position 2 is provided with a frame box body embracing device 24 that surrounds the frame box body paperboard face paper lapping material mold, which is used to surround the frame box body paperboard face paper lapping material (which can be referred to as material) on the box body horizontal forming mold 100 (up, down, left, and right sides) staying at the second mold staying position 2. The frame box body embracing device 24 has various structures and is relatively mature, such as the related structures in CN218286882U paper box forming equipment production line, CN104842586A paper box forming machine, CN104842588A paper box forming machine side forming mechanism, CN216330403U paper box forming embracing mechanism 23, CN219968976U frame forming mechanism, CN218257048U side forming mechanism of a paper box forming machine, etc.

[0044] The third mold stop position 3 is provided with a frame box body upper side outer wall surface paper supplementing and covering device 300. The horizontal frame box body has been surrounded on the box body horizontal forming mold 100 at the second mold stop position 2, and is moved to the third mold stop position 3 by the box body horizontal forming mold 100. The frame box body upper side outer wall surface paper supplementing and covering device 300 supplements and covers a complete face paper 101 on the upper side outer wall of the horizontal frame box body 200, which not only provides a new manufacturing method, i.e., additional face paper supplementing and covering, to meet different process manufacturing requirements, but also is more stable and efficient during the covering process. The upper side outer wall of the horizontal frame box body does not need to be covered with the part of the face paper in advance, and the box body material does not need to have the part of the face paper to form the frame box body, avoiding the problems of instability, skew, low quality and low efficiency when the long strip of face paper is folded and surrounded on the upper side outer wall. Even the surrounding process of the frame box body in the previous process (i.e., the second mold stop position 2) can be simplified, and the face paper in the box body paperboard face paper material in the frame box body does not need to be too long. Compared with the prior art, such as the paper box forming machine of CN104842586A, for relatively narrow and long strip materials, the long strip of material (long strip of paperboard and face paper) is unstable during the final surrounding process, and the uncapped face paper (in the rightmost area) is narrow, long and soft, which is prone to instability during the folding and surrounding process, and the face paper is not easy to fold in place and skew. Moreover, the uncapped face paper (in the rightmost area) needs to be capped from the right to the left (and reset after capping) during the folding and surrounding process, so that it is completely capped on the paperboard. For materials with a long size, the capping efficiency is low.

[0045] The fourth mold stop position 4 is provided with a demolding and boxing device 40. The frame paper box formed by the main machine is demolded and taken out by the demolding and boxing device 40, so that the frame paper box is separated from the box body horizontal forming mold 100. The demolding and boxing device 40 is a mature technology, such as the boxing mechanism of the paper box forming machine of CN104842586A, CN213261359U, and CN219544134U. The boxing structure can be moved out by clamping the box body or hooking the box mouth. After boxing, the horizontal frame paper box can be turned into a vertical frame paper box by a turnover mechanism or a grid, which is convenient for stable transportation. The post-pressing machine can adopt a vertical pressing machine (even with a fourth mouth wrapping function).

[0046] In the frame paper box forming main machine 73, the cover paper supplementing and pasting device 300 supplements and pastes a complete cover paper 101 (which can be called a separate cover paper or a split cover paper) to the upper side outer wall of the horizontal frame box body at the third mold stop position 3 to paste the cover (completely cover), which not only provides a new manufacturing method, i.e., additional cover paper supplementing and pasting, to meet different process manufacturing needs, but also is more stable when pasting the cover and has relatively high efficiency. The upper side outer wall of the horizontal frame box body does not need to paste the cover paper in advance, and the box body material does not need to have the part of the cover paper to form the frame box body, which avoids the problems of instability, skew, low quality, and low efficiency when the long strip of cover paper is folded and surrounded on the upper side outer wall. Even the frame box body surrounding process in the previous process (i.e., the second mold stop position 2) can be simplified, and the cover paper in the cover paper material in the box body paperboard in the frame box body does not need to be too long. In combination with the corresponding operations at the first mold stop position 1, the second mold stop position 2, the third mold stop position 3, and the fourth mold stop position 4, the frame paper box forming machine can realize the forming operation of the frame paper box in the main machine. The frame paper box forming machine can use the following box body paperboard cover paper pasting material (i.e., the material in the embodiment, or the box body material), in which the box body paperboard (corresponding to the four side walls of the box body) uses four-ply paperboard 102 (which can form a four-ply structure by slotting), the left one ply of the paperboard has no cover paper pasted on the lower surface, and the right three plies of the paperboard have cover paper pasted on the lower surface. In addition, the right side of the cover paper has a part that exceeds the right side edge of the paperboard (i.e., a cover paper flange narrow edge strip), i.e., the cover paper is a three-ply cover paper 103 corresponding to the box body (three side wall covers).

[0047] The following optimizations or further explanations can be made based on the above embodiments, respectively.

[0048] For example, the frame paper box forming host 73 further comprises a folding paper pasting and bottom connecting device for connecting the edge of the box body surface paper and the box bottom plate; wherein the box body surface paper (including three surface papers and single surface paper) further has a folding edge bottom connecting part 106 for pasting on the box bottom plate. The folding edge part of the box body surface paper is folded to the (up, down, left and right) four side edge positions of the box bottom plate (which has been installed on the outer end surface 1001 of the box body horizontal forming die 100 at the first mold stop position 1) by the cooperation of the folding paper pasting and connecting device. For example, the folding paper pasting and connecting device comprises a box bottom plate left edge folding paper pasting part 51, a box bottom plate right edge folding paper pasting part 52, a box bottom plate upper edge folding paper pasting part 53 and a box bottom plate lower edge folding paper pasting part 54; for example, the box bottom plate left edge folding paper pasting part 51 and the box bottom plate right edge folding paper pasting part 52 are arranged at the second mold stop position 2, the box bottom plate lower edge folding paper pasting part 54 is arranged at the third mold stop position 3, and the box bottom plate upper edge folding paper pasting part 53 is arranged at the fourth mold stop position 4. Such distribution is relatively more reasonable and can adapt to other forming operations of each stop position, and is more efficient. These folding paper pasting parts can select folding paper rollers, folding paper brushes or folding paper boards for operation, and there are many structure modes; for example, the box bottom plate left edge folding paper pasting part 51 and the box bottom plate right edge folding paper pasting part 52 at the second mold stop position 2 respectively adopt folding paper boards driven by air cylinders or motors to move left and right (even can be obliquely forward and backward), and the folding paper pasting parts at the third mold stop position 3 and the fourth mold stop position 4 respectively adopt folding paper rollers driven by air cylinders 531, 541 or motors to move up and down.

[0049] In addition, the lower side of the third mold stop position 3 is further provided with a lower pressing plate 32, and the lower pressing plate 32 is in transmission connection with a lower pressing plate lifting driving part 321 (such as containing an air cylinder or a motor); the lower side of the fourth mold stop position 4 is further provided with an upper pressing plate 55, and the upper pressing plate 55 is in transmission connection with an upper pressing plate lifting driving part 56 (such as containing an air cylinder or a motor); the upper pressing plate 55 is driven by the upper pressing plate lifting driving part 56 to operate up and down, and cooperates with the upper box body horizontal forming die 100 to press and stabilize the box body horizontal forming die 100 at the stop position, and can press and stabilize the folding paper pasting of the box body in the corresponding direction edge.

[0050] In order to smoothly input the (box body paperboard and surface paper laminating) material to the frame paper box forming host 73, a material conveying device 57 can also be connected at the second mold staying position 2, wherein the material conveying device 57 is sequentially connected with the material laminating station 58, the three-port edge covering station 60 and the second mold staying position 2. The material laminating station 58 is used for laminating the material in this embodiment (laminating the paperboard on the surface-glued surface paper). The three-port edge covering station 60 is used for covering the edge of the box body corresponding to the three side walls (the left and right lower three side walls of the box body in the horizontal state) of the four side walls of the frame paper box. The laminated material is moved from the material laminating station 58 to the three-port edge covering station 60 (for three-port edge covering) by the material conveying device 57, and then the material with three-port edge covering is conveyed from the three-port edge covering station 60 to the second mold staying position 2. The material conveying device 57 can be formed by a material conveying belt 62, an air nozzle mechanical hand, a movable air claw or the like alone or in combination. The material conveying device 57 and the cooperating structure at the material laminating station 58, the three-port edge covering station 60 and the second mold staying position 2 are also relatively mature, such as the material conveying device 57 and the cooperating structure in CN104842586A paper box forming machine, CN218286882U paper box forming equipment production line, CN221892651U paper box forming equipment and the like. In this embodiment, the frame paper box forming host 73 can be provided with a fourth-port edge covering mechanism to cover the fourth port of the box body. Of course, the fourth-port edge covering can also be completed in the subsequent production line. Even the host can not cover the box port.

[0051] The material laminating station 58 is connected with the material laminating device 59 for laminating the surface paper of the box body paperboard. The material laminating device 59 (or positioning machine or paperboard cover mechanism, which is a mature technology) laminates the paperboard on the surface-glued surface paper.

[0052] The three-port edge covering station 60 is connected with the flat paperboard three-port surface paper edge covering device 61 for covering the left and right lower three side ports of the horizontal frame box body. The flat paperboard three-port surface paper edge covering device 61 covers the surface paper of the box body paperboard (four-ply paperboard) corresponding to the left and right lower three side ports of the box body (i.e., the right three-ply paperboard). The flat paperboard three-port surface paper edge covering device 61 is a mature technology, which has a covering plate that can be lifted and horizontally moved. The lifting and horizontal movement can be respectively driven by a pneumatic cylinder or a motor (such as a servo motor with a screw nut mechanism).

[0053] It can be further illustrated that the material pasting device 59 comprises a box body flat four-up paper board and a box body material pasting mechanism for completing pasting of the face paper on the area of the outer wall face paper of the upper side of the horizontal surrounding frame box body lacking (i.e. without) the corresponding cover, i.e. in the present embodiment, the box body material is pasted by the right three-up of the four-up paper board and the corresponding face paper of the lower (three-up), wherein the face paper lacking the corresponding cover on the area of the outer wall face paper of the upper side of the horizontal surrounding frame box body is the three-up face paper of the box body side wall, and the three-up face paper of the box body side wall has a face paper flange narrow edge strip on the left and right respectively for lap joint connection, which can also avoid the exposure of the inner paper board at the edge after lap joint. The corresponding paper board is placed on the corresponding face paper with surface glue in the material pasting device 59 to complete pasting. The tail end of the three-up face paper of the box body side wall has a folding edge connecting bottom part 106, and the tail end of the separately pasted face paper in the surrounding frame box body upper side outer wall face paper pasting cover device 300 has a folding edge connecting bottom part 106; the head end of the three-up face paper of the box body side wall has a box mouth edge covering part 107, and the head end of the separately pasted face paper in the surrounding frame box body upper side outer wall face paper pasting cover device 300 has a box mouth edge covering part 107, so as to additionally realize box mouth edge covering in the main machine or production line, of course, it can also be unnecessary.

[0054] Therefore, the surrounding frame box body holding device 24 adopts the surrounding frame box body holding device 24 for pasting the box body paper board face paper pasting material lacking (i.e. without) the corresponding cover on the area of the outer wall face paper of the upper side of the horizontal surrounding frame box body. Then, the separately pasted face paper 101 can be supplemented and pasted by the surrounding frame box body upper side outer wall face paper pasting cover device 300 to the corresponding cover on the upper side of the horizontal surrounding frame box body 200.

[0055] In the embodiment of the present embodiment, the surrounding frame box body upper side outer wall face paper pasting cover device 300 has an upper side face paper pasting cover work station; wherein the upper side face paper pasting cover work station is arranged on the upper side of the third mold stopping position 3, so as to perform corresponding face paper 101 pasting cover at the upper side position; in addition, the surrounding frame box body upper side outer wall face paper pasting cover device 300 further comprises an upper side face paper feeding device 30 and a paper taking and transferring pasting cover device 31,

[0056] The upper side paper 101 is supplied to the subsequent operation (such as the paper taking and transferring cover pasting device 31) by the cooperation of the upper side paper feeding device 30, wherein the upper side paper feeding device 30 is connected with the upper side paper supplementing and cover pasting station through the paper taking and transferring cover pasting device 31, the paper taking and transferring cover pasting device 31 takes away the upper side paper supplied by the upper side paper feeding device 30 and transfers it to the upper side paper supplementing and cover pasting station, and the cooperation of the cover pasting is carried out at the upper side paper supplementing and cover pasting station, so as to realize the supplementing and cover pasting of the upper side wall of the horizontal frame box body 200 by the complete paper 101.

[0057] The upper side wall paper supplementing and cover pasting device 300 of the horizontal frame box body can supplement a complete paper to the upper side wall of the horizontal frame box body for cover pasting (complete full-width covering), and the supplementing and cover pasting of the complete paper not only provides a new frame manufacturing matching mode, but also is more stable during cover pasting and has relatively high efficiency. The upper side wall of the horizontal frame box body does not need to be pasted with the part of the paper in advance, and the box body material does not need to have the part of the paper to form the frame box body, so as to avoid the problems of instability, skew, low quality and low efficiency when the long strip paper is folded and surrounded on the upper side wall. Even the surrounding process in the previous process can be simplified, and the paper in the box body paperboard paper material in the frame box body does not need to be too long.

[0058] For example, a horizontal frame box body is manufactured by surrounding and forming the four side walls of the box body by the pasting of the paperboard and the paper, for example, the four-union paperboard 102 (which can form a four-union structure by slotting) is used as the box body paperboard, the left one union of the paperboard does not have the cover pasting paper on the lower side, the right three unions of the paperboard are pasted on the cover paper on the lower side, and the right side of the paper has a part (i.e. the paper flange narrow edge strip 105) beyond the right side edge of the paperboard, that is, the paper is three-union paper 103 corresponding to the three side walls of the box body (cover pasting). During the connection of the upper side of the horizontal frame box body, the box body horizontal forming die 100 has stopped at the second die stopping position 2, and the paperboard part (the leftmost one union of the paperboard) in the material (including the pre-glued paper and the paperboard pasted thereon) has been folded to the upper side of the second die stopping position 2 to cooperate with the surrounding die, that is, the paperboard part without cover pasting in the material is folded to the upper side of the box body horizontal forming die 100.

[0059] The following optimizations or further explanations can be made on the basis of the above embodiments.

[0060] For example, the lower side of the third mold stop position 3 is equipped with a lower pressing plate 32, and the lower pressing plate 32 is in transmission connection with a lower pressing lifting driving component 321 (such as a cylinder or a motor, etc.). The lower pressing lifting driving component 321 drives the lower pressing plate 32 to lift and act, which can press (from below) the mold (i.e. the horizontal forming mold 100 of the box body) running and stopping at the third mold stop position 3, that is, the lower pressing plate 32 can press the mold from below, and when the cover pasting device 31 above the third mold stop position 3 presses and pastes the cover, it is more stable, the mold is more balanced in force, and the cover pasting effect is better.

[0061] For example, the upper side paper feeding device 30 includes a feeding table 301, which is arranged on the front side of the third mold stop position 3 (i.e. the side of the third mold stop position 3 facing the box body bottom plate position, i.e. the front side), and the feeding table 301 provides single paper feeding.

[0062] For example, the cover pasting device 31 includes a paper suction and release plate 311, which has a suction and release paper nozzle part 3111, and the suction and release paper nozzle part 3111 is arranged downward, and when the suction and release paper nozzle part 3111 is in negative pressure suction, it can suck the paper, and when it is not in suction (such as air break or air connection), it can release the paper, wherein the paper suction and release plate 311 has multiple moving track modes (such as lifting, rotating, translating, etc.), and in this embodiment, a relatively simple and stable operation mode is adopted, that is, the paper suction and release plate 311 performs lifting and translation combined action when it operates, wherein the paper suction and release plate 311 is in transmission connection with a paper pasting lifting and translation driving component 312, that is, the paper pasting lifting and translation driving component 312 (such as a motor or a cylinder, etc.) drives the paper suction and release plate 311 to perform corresponding lifting and translation.

[0063] Further optimization includes a feeding table 301 with a material-supporting surface 302 (such as a material-supporting plate). A single sheet of face paper is placed on the feeding table 301 and supported by the material-supporting surface 302, ensuring the face paper is laid flat. The feeding table 301 is also equipped with a face paper positioning and correction mechanism 303, which can position and correct the single sheet of face paper on the feeding table 301 to ensure accurate relative positioning during subsequent cover mounting. For example, the face paper positioning and correction mechanism 303 includes a side pusher 304, which is connected to a correction drive component 305 (such as a cylinder or motor). The correction drive component 305 drives the side pusher 304 to move back and forth to cooperate with positioning correction and return to its original position. The layout of the side pusher 304 can be configured according to requirements. For example, side pushers 304 can be configured on the left, right, and front sides of the feeding table 301 (its material-supporting surface 302), while a limit stop 306 can be fixedly installed on the rear side. There are many layout configurations, which will not be elaborated here. In addition, a lifting paper feeding platform 33 is provided next to the feeding platform 301. The lifting paper feeding platform 33 has many structural designs and is relatively mature. For example, the lifting paper feeding platform 33 includes a lifting paper feeding support frame 331, which is connected to the lifting paper feeding drive motor 332. The lifting paper feeding drive motor 332 (such as a servo motor) drives the lifting paper feeding support frame 331 of the lifting paper feeding platform 33 to rise and fall. During the rising process, the paper stacked on it is gradually supplied upwards. A paper feeding input and transfer mechanism 34 is connected between the lifting paper feeding platform 33 and the feeding platform 301. The paper feeding input and transfer mechanism 34 can input and transfer the paper supplied upwards by the lifting paper feeding platform 33 (such as the top stack of paper) one by one to the feeding platform 301 (such as its support plate). There are various methods for the paper feeding and transfer mechanism 34. For example, the paper feeding and transfer can be performed by a feeder feeding structure. Alternatively, the paper feeding and transfer mechanism 34 includes a lifting and translating suction and release nozzle 341 (which works to hold the paper under negative pressure and releases the paper when the negative pressure is released). The lifting and translating suction and release nozzle 341 is connected to the feeding lifting and translating drive component 342. The feeding lifting and translating drive component 342 drives the lifting and translating suction and release nozzle 341 to lift and translate. During operation, the lifting and translating suction and release nozzle 341 descends to hold the paper on the lifting paper feeding table 33 (the top layer of the stack). Then, the lifting and translating suction and release nozzle 341 rises to lift the paper. After that, it translates and transfers the paper to the feeding table 301, where it can be released directly or descends and then released onto the feeding table 301. Finally, the lifting and translating suction and release nozzle 341 returns to its original position to wait for the next operation. The feeding lifting and translation drive component 342 may include a translation drive cylinder 343 and a lifting drive cylinder 344. It can be configured with corresponding translation and lifting tracks for stable operation. In the figure, the translation drive cylinder 343 drives the translation slide plate 345 to move back and forth, and the lifting drive cylinder 344 drives the lifting and translation suction and discharge nozzle 341 to be installed on the translation slide plate 345 to perform lifting and lowering actions.The lower side of the face paper suction and placement plate 311 is provided with a paper taking and mounting flat surface, which is relatively more stable during paper taking and mounting and pressing, and ensures that the face paper is relatively flat. The suction and paper taking air nozzle part 3111 can be distributed on the paper taking and mounting flat surface, and the processing is also relatively convenient. For example, the paper taking and mounting lifting and translation driving part 312 can include a paper taking and mounting lifting driving motor 3121 (such as a servo motor) and a paper taking and mounting translation driving motor 3122 (such as a servo motor). The paper taking and mounting translation driving motor 3122 (which can be driven by a belt transmission structure) cooperates to drive the translation plate 3123 to move horizontally, which is relatively accurate, stable, adjustable, and controllable. The paper taking and mounting lifting driving motor 3121 (which can be driven by a screw and nut transmission structure) cooperates to drive the face paper suction and placement plate 311 to move up and down on the translation plate 3123, which is relatively accurate, stable, adjustable, and controllable. The translation and lifting can be configured with a corresponding track 310 for stable operation. In the figure, the paper taking and mounting lifting driving motor 3121 drives the lifting plate 3124 to move up and down on the translation plate 3123 through the screw and nut mechanism 313 (the nut is mounted on the lifting plate 3124). The lifting plate 3124 is connected to the support plate 3126 below through the connecting sleeve 3125. The screw can pass through the connecting sleeve 3125. The support plate 3126 is provided with a mounting plate 3127 below. The support plate 3126 and the mounting plate 3127 are provided with a buffer spring 3128. When the pressure is lowered, the buffer effect can be achieved, which can adapt to the deviation of the thickness of the face paper. The paper taking and mounting is relatively more accurate. A guide rod 3129 can be arranged between the support plate 3126 and the mounting plate 3127. The spring is arranged on the guide rod 3129. In addition, the upper end of the guide rod 3129 is provided with an adjusting nut, which can adjust the compression amount of the buffer spring 3128. The face paper suction and placement plate 311 is assembled on the mounting plate 3127. The inside of the face paper suction and placement plate 311 can be provided with a gas path (such as a gas groove, a gas chamber, etc.), which can divide the face paper suction and placement plate 311 into an upper plate and a lower plate combination structure, which is convenient for internal gas path processing and setting.

[0064] The horizontal frame box body side outer wall paper supplementing and pasting cover device 300 further comprises a lower side of the paper gluing mechanism 35, which is arranged below the paper taking and transferring pasting cover device 31. The lower side of the paper gluing mechanism 35 glues the lower side of the paper supplementing and pasting cover. Directly gluing the paper makes the structure relatively reasonable and compact, and there is no need to glue in advance on the horizontal frame box body side outer wall to be pasted (such as glue spraying). The lower side of the paper gluing mechanism 35 can cooperate with the paper taking and transferring pasting cover device 31 to complete the lower layer (surface) gluing of the paper during the paper taking and transferring process, which is more convenient and practical. The lower side of the paper gluing mechanism 35 is arranged below the paper taking and transferring pasting cover device 31, which can cooperate efficiently and glue during the paper taking and transferring process of the paper taking and transferring pasting cover device 31. For example, the lower side of the paper gluing mechanism 35 is arranged between the upper side of the paper feeding device 30 and the third mold resting position 3, which makes the structure more compact and the paper taking and transferring path of the paper taking and transferring pasting cover device 31 more reasonable. The lower side of the paper gluing mechanism 35 has various gluing methods, such as spraying, rolling, brushing, etc. In this embodiment, the lower side of the paper gluing mechanism 35 comprises a glue roller 351, which is arranged below the transferring path of the paper suction and pressing plate 311 of the paper taking and transferring pasting cover device 31. The glue roller 351 rotates to efficiently roll glue. For example, the paper suction and pressing plate 311 translates to transfer the paper above the glue roller 351, which cooperates with the contact gluing. The glue roller 351 has a mature gluing method. For example, the lower side of the glue roller 351 is provided with a glue feeding roller 352, and the bottom of the glue feeding roller 352 is provided with a glue tank 353. The glue feeding roller 352 rotates to transfer the glue in the glue tank 353 to the glue roller 351 and makes the glue layer on the glue roller 351 more uniform. The glue roller 351 and the glue feeding roller 352 can use the same glue applying motor 354 and utilize gear 359 meshing transmission (gear meshing has a gap). The pressure between the glue feeding roller 352 and the glue roller 351 can be adjusted to adjust the thickness of the glue. For example, the bearings at both ends of the glue feeding roller 352 are connected with an adjusting screw 355. In addition, the glue tank 353 can be matched and inserted into the lifting and separating tank 356 (which can be matched with a separating cylinder 358 to switch the state), and the glue tank 353 can be moved out to the auxiliary supporting plate 357 after the lifting and separating tank 356 is lowered, so as to be cleaned, replaced, etc. When in use, the glue tank 353 is pushed from the auxiliary supporting plate 357 to the lifting and separating tank 356, and the lifting and separating tank 356 is raised to move the glue tank 353 to the position, so that the glue feeding roller 352 can transfer the glue in the glue tank 353. The third mold resting position 3 is used for the resting of the box body horizontal forming mold 100 during operation. For example, the third mold resting position 3 is provided with the box body horizontal forming mold 100 which intermittently rotates around the vertical center axis to rest, so that the box body horizontal forming mold 100 can perform other operations at other resting positions during the intermittent rotation and resting process, such as the horizontal frame box body surrounding on the mold at the previous position.

[0065] In addition, the front side of the third mold stop position 3 is also provided with a heating device 90. The heating device can include a heating shell, and an electric heating air, an oven lamp, a heating tube or a combination thereof can be arranged in the heating shell as a heating source. The heating device can heat the cover paper on the cover to make the glue on the cover paper act quickly to quickly and firmly glue the cover paper. In particular, the edge of the tail end of the cover paper (i.e. the single cover paper) is heated, which helps the edge (the relatively small area) to quickly play a role in adhering to the bottom plate of the box in the subsequent (e.g. the next mold stop position). The heating device 90 is located on the upper side of the third mold stop position 3, and the height position (e.g. the lifting heating shell) and the angle position (e.g. the rotating heating shell) of the heating device 90 are adjusted and set.

[0066] In the embodiment of the present application, the horizontal frame box body surrounding and forming device comprises an upper side connecting mechanism 20 arranged on the upper side of the second mold stop position 2. The second mold stop position 2 is used for stopping the box body horizontal forming mold 100 to cooperate with the surrounding and forming of the frame box body. The upper side connecting mechanism 20 (arranged on the upper side of the second mold stop position 2) is used for cooperating with the upper side connection of the frame box body. The upper side connecting mechanism 20 comprises a downward pressure plate 21 and a horizontal edge paper lapping component 22. The downward pressure plate 21 is in transmission connection with a pressure plate lifting driving component 211 (such as a motor or a cylinder), and is driven by the pressure plate lifting driving component 211 to perform lifting action. The horizontal edge paper lapping component 22 is in transmission connection with a first horizontal driving component 221 (such as a motor or a cylinder), and is driven by the first horizontal driving component 221 to perform horizontal action to lap the edge paper.

[0067] For example, a horizontal frame box body is made by surrounding and forming a box body four side wall with paperboard and cover paper. For example, the box body paperboard adopts four joint paperboard (which can form a four joint structure by slotting), the left side of the paperboard has no cover paper, and the right side of the paperboard has cover paper. In addition, the right side of the cover paper has a part (i.e. a cover paper flange narrow edge strip) that exceeds the right side edge of the paperboard. That is, the cover paper is three joint cover paper corresponding to the box body (three side wall cover). During the upper side connection of the horizontal frame box body surrounding process, the box body horizontal forming mold 100 has stopped at the second mold stop position 2, and the paperboard part (the leftmost joint paperboard) of the material (including the pre-glued cover paper and the paperboard lapped thereon) has been folded to the upper side of the second mold stop position 2 to cooperate with the surrounding mold, that is, the paperboard part without cover paper has been folded to the upper side of the box body horizontal forming mold 100.

[0068] At this time, the upper connecting mechanism 20 starts to work, and the lower pressing plate 21 is lowered to press the lower second mold stop position 2 (at this time, the upper side of the horizontal box body forming mold 100 is stopped) to cooperate with the paperboard part (the leftmost paperboard of the material) on the upper side, so that the relative position of the paperboard part is in place and stable state and cannot be moved (to ensure that the subsequent lap joint is firm and stable), and then the horizontal edge paper pasting and lap joint component 22 moves horizontally to cooperate with the second mold stop position 2 (at this time, the right side of the horizontal box body forming mold 100 is stopped) on the right side of the second mold stop position 2 (at this time, the right side of the horizontal box body forming mold 100 is stopped) to paste the paper part (the narrow edge strip of the paper flange of the material) on the right edge of the upper paperboard part (the leftmost paperboard of the material). The paper part (the narrow edge strip of the paper flange of the material) is folded to the outside of the right edge of the upper paperboard part of the second mold stop position 2 (at this time, the right edge of the horizontal box body forming mold 100 is stopped), realizing the lap joint of the paper and the paperboard, realizing the folding of the right paper part to the upper paperboard part and the lap joint of the paper, completing the upper connection of the horizontal surrounding frame box body, and only the horizontal movement of the paper flange narrow edge strip is needed to complete the lap joint of the paper, and the horizontal movement stroke is relatively short, which is more efficient. Then the lower pressing plate 21 (rises) and the horizontal edge paper pasting and lap joint component 22 (moves to the right) are reset to wait for the next work.

[0069] The horizontal surrounding frame box body surrounding forming device can meet the upper connection manufacturing of the new horizontal surrounding frame box body, is more stable and efficient, and has simple action.

[0070] The following optimizations or further explanations can be made based on the above embodiments.

[0071] For example, the front and rear of the lower pressing plate 21 is respectively connected with a paperboard guiding and correcting component 212, and the paperboard guiding and correcting components 212 are paperboard centering areas. During the lowering process of the lower pressing plate 21, the paperboard part (the leftmost paperboard of the material) on the upper side of the second mold stop position 2 (at this time, the upper side of the horizontal box body forming mold 100 is stopped) is guided and centered by the front and rear paperboard guiding and correcting components 212 to cooperate with the lower pressing plate 21, so that the relative position of the paperboard part does not deviate. The opposite sides (i.e., the opposite sides facing each other) of the paperboard guiding and correcting components 212 are provided with guiding and correcting surfaces (such as inclined surfaces), and the front and / or rear paperboard guiding and correcting components 212 are adjustably installed on the lower pressing plate 21, such as fastener disassembly and adjustment installation. After adjusting the front and rear positions, different sizes of paperboards can be met, which is more practical.

[0072] For example, the first horizontal movement frame 222 is in transmission connection with the first horizontal movement driving part 221, and is driven by the first horizontal movement driving part 221 to move left and right horizontally (i.e. horizontal movement). The horizontal movement edge paper clamping part 22 is installed on the first horizontal movement frame 222, and moves horizontally with the first horizontal movement frame 222. The second horizontal movement frame 215 is in transmission connection with the second horizontal movement driving part 214 (such as a motor or a pneumatic cylinder), and is driven by the second horizontal movement driving part 214 to move left and right horizontally (i.e. horizontal movement). The downward pressing plate 21 and the pressing plate lifting driving part 211 are installed on the second horizontal movement frame 215, and move horizontally with the second horizontal movement frame 215, so that the downward pressing plate 21 can also move horizontally. This can be used to adjust the horizontal position to meet the size specification requirements of the frame, and can also increase the degree of freedom of movement during operation, or even avoid obstacles by moving horizontally, so that the paperboard part (the leftmost paperboard) can be more smoothly turned to the upper side of the second mold resting position 2 (i.e. the upper side of the horizontal forming mold 100 of the box body), and then moved back to press the downward pressing plate 21. Horizontal movement can make the lifting stroke of the downward pressing plate 21 smaller. In the figure, the first horizontal movement driving part 221 and the second horizontal movement driving part 214 are in transmission connection with the motor through a belt transmission mode.

[0073] The pressing plate lifting driving part 211 is in transmission connection with the pressing plate lifting seat 213, and the downward pressing plate 21 is installed on the pressing plate lifting seat 213 and is adjustably installed on the pressing plate lifting seat 213 in terms of height, so as to be adjusted by lifting to ensure smooth operation and meet the size specification requirements of the frame, such as being detachably installed by using fasteners and vertical installation holes. Similarly, the horizontal movement edge paper clamping part 22 is adjustably installed on the first horizontal movement frame 222 in terms of height.

[0074] In addition, the horizontal frame box body surrounding forming device also includes a holding mechanism 23, which includes a lifting top plate 231 arranged below the second mold resting position 2 and a side folding holding and turning plate 232 arranged on the left and right sides of the second mold resting position 2. The holding mechanism 23 is a mature technology, such as the side forming mechanism of the paper box forming machine in CN104842588A, the paper box forming equipment production line in CN218286882U, the paper box forming holding mechanism 23 in CN216330403U, and the frame forming mechanism in CN219968976U.

[0075] In the figure, the holding mechanism 23 is driven by the holding main motor through the bevel gear steering transmission pair to drive the two connecting rods of the conjugate cam, and the two connecting rods drive the lifting top plate 231 to lift and the side folding holding turnover plate 232 to overturn (two groups are arranged on the left and right), and the synchronous spline shaft drives the intermediate cam to swing through the connecting rod to drive the lifting top plate 231 to lift, forming three groups of lifting top plates 231 on the left, in the middle and on the right to match the surrounding frame requirements. The left support and the right support can be adjusted in left and right positions respectively to meet the size specification change requirements of the surrounding frame. The side folding holding turnover plate 232 on the left and the lifting top plate 231 are arranged on the left support, and the side folding holding turnover plate 232 on the right and the lifting top plate are arranged on the right support. The left support and the right support respectively have corresponding bevel gear steering transmission pairs, conjugate cams and two connecting rods.

[0076] Further optimization, each side of the side folding and holding turnover plate 232 includes a turnover plate body (with a corresponding turnover shaft 234 for supporting its turnover action), the turnover plate body includes a main plate 2321 and an extended auxiliary plate 2322, the extended auxiliary plate 2322 is connected with the main plate 2321, the main plate 2321 is at the turnover root position (i.e. relatively close to the line of the turnover shaft 234) relative to the extended auxiliary plate 2322, the extended auxiliary plate 2322 is extended or retracted relative to the main plate 2321, the combination structure of the main plate 2321 and the extended auxiliary plate 2322 can form different turnover effective areas by adjusting, so that the turnover is more stable, and the root position can effectively turn over and press on both sides of the box body horizontal forming die 100, the paperboard turnover and folding effect is good. In addition, the side folding and holding turnover plate 232 also includes a detachable additional extension bar 2323, the detachable additional extension bar 2323 is connected and installed on the turnover plate body, by replacing and disassembling the additional extension bar 2323, different length of additional extension bar 2323 can be used to match different size specifications of the surrounding frame paper box, and the overall weight of the side folding and holding turnover plate 232 is relatively low, and the operation is relatively stable. Among them, the extended auxiliary plate 2322 is slidably adjusted relative to the main plate 2321, such as the sliding adjustment of the sliding groove, to realize the extension or retraction adjustment. In addition, the turnover plate body is provided with a width adjusting seat 2324, and the additional extension bar 2323 is arranged on the width adjusting seat 2324, which is used to adjust the width position of the additional extension bar 2323 before and after the turnover plate body, so as to meet the different specifications of the height of the horizontal surrounding frame box body, so that the turnover is more stable; the width adjusting seat 2324 can be connected and arranged on the width adjusting sliding groove 2325 of the extended auxiliary plate 2322. Of course, the additional extension bar 2323 is also arranged on the turnover plate body in a relatively fixed position, and the additional extension bar 2323 in a relatively fixed position is usually arranged at the edge position corresponding to the front of the surrounding frame box body (i.e. the side facing outward of the die), so as to be more stable for subsequent connection of the box bottom plate edge covering surface paper. The side folding and holding turnover plate 232 can also be provided with a box opening limiting plate, which can be limited when the material is put in, so as to be accurate in relative position, and also helps the material to be turned over to the die (left and right sides) without position deviation.

[0077] In the embrace mechanism 23 embrace, for example, the material in this embodiment (paperboard and tissue paper) is taken, the right second paperboard is lifted by the lifting top plate 231 to the bottom side of the box body horizontal forming die 100, and the left and right side folding embrace flip plates 232 respectively flip the left second paperboard and the rightmost paperboard to the left and right sides of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here). During the flipping process, the left side folding embrace flip plate 232 also flips the left first paperboard (i.e. the leftmost paperboard) together, and can also flip the leftmost paperboard to the upper side of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here) by inertia.

[0078] In order to make the left first paperboard flip to the upper side of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here) more smoothly, further optimization, the left side folding embrace flip plate 232 is also provided with an upper paperboard folding auxiliary block 2326. When the left side folding embrace flip plate 232 is flipped into position, the leftmost paperboard is folded to the upper side of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here) by inertia, and the upper paperboard folding auxiliary block 2326 can also be used to smoothly press and fold the leftmost paperboard to the upper side of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here); for example, the upper paperboard folding auxiliary block 2326 and the left side folding embrace flip plate 232 have an upper paperboard folding corner, which can cover the upper side (left) corner position of the second die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here), thereby facilitating the folding of the upper paperboard; in addition, the upper paperboard folding auxiliary block 2326 is adjustably arranged on the folding radius position of the folding embrace flip plate 232, so as to adjust the size of the frame box body to meet different requirements. In addition to the above method, or an active upper paperboard folding auxiliary block (not shown) can also be used, which is arranged on the left side folding embrace flip plate and is provided with a pressure source for assisting the mold top surface. The pressure source drives the folding embrace flip plate to exert additional pressure and return. When the paperboard (the left one) is folded to the upper side of the third die stop position 2 (at this time, the box body horizontal forming die 100 is stopped here) by the folding embrace flip plate 232, the upper paperboard folding auxiliary block can also be used to assist in exerting additional pressure on the paperboard to ensure that it is folded into position; for example, the pressure source is a pressure cylinder which is in transmission connection with the upper paperboard folding auxiliary block.

[0079] It is to be supplemented that the second mold staying position 2 is provided with a box horizontal forming mold 100 which intermittently rotates and stays around the vertical center axis; the front side or the left side or the right side between the second mold staying position 2 and the lifting top plate 231 is the material input side, so that the paperboard and the face paper are input to be laminated, and the subsequent surrounding mold operation of the horizontal surrounding box body surrounding forming device is carried out. The material input mode is various, which can be directly input by a conveying belt, or can be input by a lifting and translating air nozzle (i.e. material input manipulator 63), or can be input by a robot (including a multi-axis mechanical arm) with a suction nozzle. In addition, the top surface of the box horizontal forming mold 100 is also provided with a box opening limiting step (not shown in the figure), which is formed by setting a layer plate, for example, to limit the paperboard on the top surface and prevent the paperboard above from moving and shifting towards the box opening (vertical center axis).

[0080] In the surrounding paper box forming production, the surrounding box body forming process is that the surrounding box body is surrounded by the box body material on the horizontal box body forming mold, the box body material is the four-up paperboard and the three-up face paper laminated material, the rightmost paperboard in the four-up paperboard is not laminated with the three-up face paper, and after the box body material is surrounded into the surrounding box body, a single face paper (i.e. additional face paper) is additionally supplemented on the upper side outer wall of the surrounding box body to be laminated and covered, and the surrounding box body forming is completed. The single face paper can be sucked and laminated on the upper side outer wall of the surrounding box body by a face paper suction and pressing plate (the lower side is a paper taking, laminating and pressing surface), which is more flat and more fit. The two face papers, i.e. the three-up face paper and the single face paper, are used to avoid the problem of too long box body material and the problem of no paperboard laminated support face paper folding and laminating, and the single face paper can completely cover the upper side outer wall to avoid the exposed lap joint being not beautiful.
