[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Referring to the attached drawings, in the embodiment of this implementation manner, the carton hemming machine includes a first station 1, a second station 2, a third station 3, and a fourth station 5. The first station 1 is used for waiting for the carton to enter. The second station 2 is used for pasting the facing paper 93 on the inner side of the upper part of the carton wall. The third station 3 is used for pasting the facing paper 93 on the inner side of the lower part of the carton wall. The fourth station 5 is used for turning outwards the upper part 92 of the carton wall and corrugating the position 94 between the upper part 92 and the lower part 91 of the carton wall.

[0031] The first station 1, the second station 2, the third station 3, and the fourth station 5 are arranged longitudinally from back to front. The carton body longitudinal conveying device 6 is used to connect the front and back stations in cooperation. That is, the carton body longitudinal conveying device 6 cooperates to convey the carton body 90 from the first station 1 to the second station 2, from the second station 2 to the third station 3, and from the third station 3 to the fourth station 5. This station layout and conveying cooperation structure are relatively compact and the layout is relatively reasonable, which can meet the production requirements.

[0032] Among them, the second station 2 is equipped with a device 20 for pasting the facing paper on the inner side of the upper part of the carton wall, which cooperates to paste the facing paper on the inner side of the upper part of the carton wall (carton body 90) at the second station 2. The third station 3 is equipped with a device for pasting the facing paper on the inner side of the lower part 91 of the carton wall, which cooperates to paste the facing paper on the inner side of the lower part 91 of the carton wall (carton body 90) at the third station 3. The fourth station 5 is equipped with a hemming and corrugating device 50, which cooperates to turn the upper part 92 of the carton wall outwards and corrugate the position 94 between the upper part 92 and the lower part 91 of the carton wall at the fourth station 5. This can make the facing paper fit tightly. The facing paper fits more tightly with the end faces of the upper part 92 and the lower part 91 (paperboard) of the carton wall at this position, and it is not easy to bulge. This position (the area between the upper part 92 and the lower part 91 of the carton wall) is relatively neater, improving the quality of the carton.

[0033] Its working principle is as follows: Place the carton body 90 to be processed (the right side wall (i.e., the box wall) of the carton body has been divided into an upper part 92 and a lower part 91, and the outer surface of the box body of this box wall is also pasted with face paper) in the first station 1 and wait; The carton body waiting at the first station 1 is conveyed to the second station 2 by the cooperation of the carton body longitudinal conveying device 6; At the second station 2, the inner surface of the upper part of the box wall of the carton body (the box wall on the right side of the carton body in the present invention) is pasted with face paper by the cooperation of the inner face paper pasting device 20 of the upper part of the box wall; After the inner surface of the upper part of the box wall (box body) is pasted with face paper, the carton body at the second station 2 is conveyed to the third station 3 by the carton body longitudinal conveying device 6; At the third station 3, the inner surface of the lower part 91 of the box wall of the carton body is pasted with face paper by the cooperation of the inner face paper pasting device of the lower part of the box wall; After the inner surface of the lower part of the box wall is pasted with face paper, the carton body at the third station 3 is conveyed to the fourth station 5 by the carton body longitudinal conveying device 6; At the fourth station 5, the upper part of the box wall of the carton is folded outwards by the cooperation of the edge folding and corrugating device 50, exposing the end face of the position area between the upper and lower parts of the box wall, and then corrugating this position 94, which can make the face paper fit tightly at this position.

[0034] This carton edge folding machine can further process the type of carton whose cardboard of the box wall has been divided into an upper part and a lower part and the outer surface of the box wall (box body) is pasted with face paper, complete the surface pasting of the inner sides of the upper and lower parts (box body) of the box wall, and the face paper at the position between the upper and lower parts can also fit tightly.

[0035] Based on the above embodiments respectively, the following optimizations or further explanations can also be carried out.

[0036] The longitudinal box conveying device 6 can be a conveyor belt, a conveyor chain, etc. In this embodiment, the following structure is adopted: the longitudinal box conveying device 6 includes a left box supporting plate 61, a right box supporting plate 62, and a longitudinal box conveying component; the longitudinal box conveying component includes a box conveying unit 63, and the box conveying unit 63 includes an opening and closing driving member 64 and a front box clamping block 65 and a rear box clamping block 66; the front box clamping block 65 and the rear box clamping block 66 are paired with each other in front and back, and are used to clamp and release the paper box body 90; the opening and closing driving member 64 is connected to the front box clamping block 65 and the rear box clamping block 66 by transmission. 6, the opening and closing driving member 64 is used to drive the clamping box front block 65 and the clamping box rear block 66 to separate and close, and cooperate to clamp and release the carton box body. For example, the opening and closing driving member 64 adopts a cylinder (such as a double-headed cylinder) or a motor; wherein the box feeding unit 63 is set to lift and lower and move longitudinally forward and backward, that is, the box feeding unit 63 can lift and lower and move longitudinally forward and backward; wherein, a clamping block box feeding moving channel 67 (for example, the middle interval between the left box supporting plate 61 and the right box supporting plate 62) is provided between the left box supporting plate 61 and the right box supporting plate 62, and the clamping box front block 65 and the clamping box rear block 66 are arranged at the clamping block box feeding moving channel 67, that is, the clamping box front block 65 and the clamping box rear block 66 can move through the channel during operation (such as lifting, clamping and longitudinal movement), and the mutual cooperation is relatively more efficient. After the box feeding unit 63 sends the carton box body to the corresponding station, the left box supporting plate 61 and the right box supporting plate 62 can cooperate to support the carton box body 90 is processed at the corresponding workstation without affecting the return of the box feeding unit 63 (for example, the opening and closing driving component 64 separates the front block 65 of the clamping box from the rear block 66 of the clamping box and it descends and moves longitudinally backward) to the rear workstation to prepare for transferring the next paper box body. After the box feeding unit 63 arrives at the rear workstation, it can rise, and the opening and closing driving component 64 closes the front block 65 of the clamping box and the rear block 66 of the clamping box to clamp the paper box body of the workstation, and then moves longitudinally forward to transport the paper box body to the next workstation. Further optimization, the corresponding box delivery units 63 are respectively configured between the adjacent front and rear stations, for example, the first station 1 and the second station 2, the second station 2 and the third station 3, and the third station 3 and the fourth station 5 are all connected by the corresponding box delivery units 63. Finally, when the fourth station 5 outputs the carton body, the box delivery unit 63 between the third station 3 and the fourth station 5 can directly push the carton body originally at the fourth station 5 forward when transferring the carton body to the fourth station 5, without the need for an additional output structure. Each box delivery unit 63 can be respectively set on the lifting and longitudinal movement bracket 68, that is, all the box delivery units 63 are set on the lifting and longitudinal movement bracket 68 for synchronous operation to ensure the coordinated operation between the stations. The lifting and longitudinal movement bracket 68 can be configured with a corresponding lifting drive cylinder 681 and a longitudinal movement linear module 682.

[0037] For example, the inner surface paper device 20 on the upper part of the box wall includes a lateral gauge 21, a limit support gauge 22, a edge wrapping component 23, and an inclined pressing component 24; the inclined pressing component 24 is used to turn the upper part of the box wall outwards, and the inclined pressing component 24 is arranged above the limit support gauge 22. Among them, the lateral gauge 21 is arranged on the left side of the second station 2, and the lateral gauge 21 is drivingly connected with a gauge transverse movement driving member 210 (such as a cylinder or a motor, etc.), and the gauge transverse movement driving member 210 cooperates to drive the lateral gauge 21 to perform a transverse movement. When the paper box body is sent to the second station 2, the lateral gauge 21 can cooperate to push the paper box body to the right, so that the position of the paper box body is in a relatively accurate position waiting for processing. The limit support gauge 22 is arranged on the right side of the second station 2;

[0038] Among them, the limit support gauge 22 has a box blocking limit part 221, and the box blocking limit part 221 is located on the left side of the limit support gauge 22. The box blocking limit part 221 of the limit support gauge 22 is used to cooperate with the right side of the second station 2 to limit the paper box body, and cooperate with the lateral gauge 21 to accurately and stably position the paper box body;

[0039] Among them, the limit support and stop gauge 22 also has an edge support material matching part 222 for supporting the upper part of the box wall that is obliquely pressed and turned outward. The edge support material matching part 222 is located on the upper side of the limit support and stop gauge 22, and the oblique pressing component 24 is located above the edge support material matching part 222. The edge support material matching part 222 can not only cooperate with the oblique pressing component 24, but also when the oblique pressing component 24 is turned outward, the edge support material matching part 222 cooperates to support the upper part of the box wall that is obliquely pressed and turned outward, so that the upper part of the box wall can be turned outward smoothly and can be in a stable position pressed obliquely on the edge support material matching part 222 to wait for subsequent edge binding. The outermost upper part of the box wall is supported by the edge support material matching part 222 and the upper part of the box wall is pressed by the oblique pressing component 24, so that the upper part of the box wall is in a position to be wrapped The edge of the box is in a stable position, and the edge wrapping component 23 is configured next to the edge wrapping supporting material matching portion 222. The edge wrapping component 23 can wrap the surface paper on the outer side of the upper part of the box wall (at this time, it is below the upper part of the box wall) on the inner side of the upper part of the box wall to perform the mounting paper operation, wherein the edge wrapping component 23 is transmission connected with the edge wrapping driving component 230 (such as containing a cylinder or a motor, etc.), and the edge wrapping driving component 230 operates the edge wrapping component 23 to run and cooperate with the edge wrapping (there are many ways and they are relatively mature); wherein the box blocking limit portion 221 can adopt a vertical plane, and the edge wrapping supporting material matching portion 222 can adopt a horizontal plane, which is convenient for processing, and can be arranged on the limit support gauge 22 in one piece or in parts. For example, the limit support gauge 22 adopts a limit block, and its height matches the lower part of the box wall. The oblique pressing component 24 is connected to an oblique moving driving component 241 (such as a cylinder), and is driven by the oblique moving driving component 241 to move obliquely, and is pressed obliquely from top to bottom and from inside to outside to turn the upper part of the box wall outward onto the edge wrapping material matching part 222. In the general initial state, the box wall (upper part and lower part) of the paper box body is in a vertical state. The position of the oblique pressing component 24 acting on the upper part of the box wall can be as close to the lower edge of the upper part as possible, so that the edge wrapping component 23 can wrap the surface paper to the inner side of the upper part to the maximum extent during the (lateral) edge wrapping process.

[0040] Even, the device 20 for placing the facing paper on the inner side of the upper part of the box wall further includes a side pressure anti-displacement component 25, which is used to press the inner side of the lower part of the box wall, so as to avoid the displacement of the box wall on the right side of the paper box body and the problem of poor hemming effect caused by the displacement. During the hemming process of the hemming component 23, the oblique pressure component 24 can be returned in advance (obliquely rising) to separate from the upper part of the box wall, and the side pressure anti-displacement component 25 can also press the lower part of the box wall to prevent the box wall from shifting. The hemming component 23 on the upper side of the upper part of the box wall can continue to hem until the face paper is completely wrapped on the upper part of the box wall, ensuring that the facing paper on the inner side of the upper part of the box wall is more sufficient, full, and relatively tighter. The side pressure anti-displacement component 25 can press the lower part of the box wall on the stop box limit part 221 of the limit support stop gauge 22 to limit the position and prevent displacement. Among them, the side pressure anti-displacement component 25 is transmission-connected with a lifting and transverse movement driving component (such as a cylinder or a motor, etc.), and the lifting and transverse movement driving component cooperates to drive the side pressure anti-displacement component 25 to lift and move horizontally, so that it can smoothly enter the paper box body to perform side pressure and retract to exit the paper box body for smooth transportation.

[0041] It can be further optimized, and a lifting bracket 26 is arranged above the second workstation 2. The lifting bracket 26 can be installed with the oblique pressure component 24 and the side pressure anti-displacement component 25 to realize the lifting action together, and can be lifted and lowered above the second workstation 2, and the operation efficiency is relatively higher; wherein, the lifting and transverse movement driving components include a bracket lifting driving member 251 (such as a cylinder, etc.) and a side pressure limit transverse movement driving member (such as a cylinder, etc.), and the bracket lifting driving member 251 is connected with the lifting bracket 26 by transmission, and the bracket lifting driving member 251 cooperates with the lifting bracket 26 to drive the lifting bracket 26 to perform the lifting action The side pressure limit transverse driving member is connected to the lifting bracket 26, and the side pressure anti-displacement member 25 is connected to the side pressure limit transverse driving member by transmission transmission. The side pressure limit transverse driving member cooperates to drive the side pressure anti-displacement member 25 to perform transverse movement and side pressure action on the lifting bracket 26. The side pressure anti-displacement member 25 is connected to the lifting bracket 26, the oblique pressing member 24 is connected to the lifting bracket 26, and the oblique moving driving member 241 is connected to the lifting bracket 26. The oblique moving driving member 241 cooperates to drive the oblique pressing member 24 to perform oblique pressing on the lifting bracket 26. During operation, the lifting bracket 26 can descend to drive the oblique pressing member 24 and the side pressure anti-displacement member 25 to descend together, and the lifting bracket 26 can rise to drive them to rise together when retreating. The oblique pressing stroke is relatively small, and the operation efficiency is relatively high.

[0042] In addition, the edge wrapping driving component 230 includes an edge wrapping lifting driving member 231 (such as a cylinder or a motor, etc.) and an edge wrapping transverse movement driving member 233 (such as a cylinder or a motor, etc.). The edge wrapping lifting driving member 231 is drivingly connected to a lifting seat 232. The edge wrapping lifting driving member 231 drives the lifting seat 232 to lift and lower. The edge wrapping transverse movement driving member 233 is arranged on the lifting seat 232 and lifts and lowers together with the lifting seat 232. The edge wrapping component 23 is drivingly connected to the edge wrapping transverse movement driving member 233. The edge wrapping transverse movement driving member 233 drives the edge wrapping component 23 to move transversely on the lifting seat 232. During edge wrapping operation, the edge wrapping component 23 rises to lift up (turn upwards) the face paper that exceeds the upper edge of the box wall, and then moves transversely to the left to fold the turned-up face paper towards the inner side of the upper part of the box wall, completing the pasting of the face paper on the inner side of the upper part of the box wall. For example, the edge wrapping component 23 includes an edge wrapping plate; even a brush is provided on the lower side surface of the edge wrapping plate. When the edge wrapping plate moves transversely to the left, the brush is used to brush the turned-up face paper towards the inner side of the upper part of the box wall, making the face paper fit more tightly and smoothly with the upper part of the box wall, and also avoiding damaging the face paper.

[0043] For another example, the device 30 for pasting the face paper on the inner side of the lower part of the box wall includes a lifting and pressing pasting component 31 and a lateral pressing plate 32; the lifting and pressing pasting component 31 is arranged above the third station 3. The lifting and pressing pasting component 31 is drivingly connected to a lifting pasting driving member 311 (such as a cylinder or a motor, etc.). The lifting pasting driving member 311 drives the lifting and pressing pasting component 31 to perform lifting and lowering actions. When descending, it can press down the face paper (the part that exceeds the face paper pasted on the inner side of the upper part of the box wall) of the carton box body at the third station 3 for pasting, and when rising, it returns to its original position; the lateral pressing plate 32 is arranged on the right side of the third station 3. The lateral pressing plate 32 is drivingly connected to a transverse material pressing driving member 321 (such as a cylinder or a motor, etc.). The transverse material pressing driving member 321 cooperates to drive the lateral pressing plate 32 to move transversely (left and right) on the right side of the third station 3. The lateral pressing plate 32 is located on the right side of the lifting and pressing pasting component 31. Among them, the lifting and pressing pasting component 31 also has a bearing surface 312 facing the right for abutting against the inner side of the lower part of the box wall. When the lateral pressing plate 32 descends in place to press down the corresponding face paper for pasting, the lateral pressing plate 32 can also move transversely to the left for lateral pressing. The lifting and pressing pasting component 31 (its bearing surface 312) and the lateral pressing plate 32 clamp and press the side wall lower part of the carton box body to ensure that the face paper on the side wall lower part is firmly pasted and can eliminate the air bubbles between the face paper and the cardboard of the side wall lower part (i.e., the air bubble pressing function). The surface of the lifting and pressing pasting component 31 can be provided with anti-scratch materials such as flannelette to avoid damaging the face paper. In addition, some components can also be coated or sprayed with corresponding anti-adhesive materials as needed to avoid the glue accidentally sticking to these components and affecting the normal operation.

[0044] In addition, above the lateral pressing plate 32, there is a holding member 33 for keeping the upper part of the box wall turned outwards; the upper part of the box wall of the paper box body has been turned outwards at the second station 2, but when it is conveyed to the third station 3, there is a situation where the outward turning is reset. If the reset of the outward turning affects the lowering of the lifting and pressing paper pasting member 31, it will interfere with its normal operation. After setting the holding member 33, when the paper box body is conveyed to the third station 3, it can keep the upper part of the box wall in the outward turned state to avoid affecting the normal operation of the lifting and pressing paper pasting member 31 at the third station 3; moreover, there is a material passing gap between the lateral pressing plate 32 and the holding member 33, which does not affect the normal lateral movement of the lateral pressing plate 32. In addition, between the second station 2 and the third station 3, there is an upper box wall outward turning guide member 34 (such as a guide rod or a guide plate, etc., with the same principle as below), and the holding member 33 is connected to the upper box wall outward turning guide member 34 to ensure that when the paper box body is conveyed to the third station 3, it will not be reset and turned outwards between the stations, and the upper part of the box wall is in the outward turned state for connection. Additionally optimized, on the left side of the third station 3, there is a lateral box pushing plate 35, and the lateral box pushing plate 35 is drivingly connected to a lateral transverse box pushing driving member 351 (such as including a cylinder or a motor, etc.). The lateral transverse box pushing driving member 351 cooperates to drive the lateral box pushing plate 35 to move left and right. When moving to the right, it pushes the paper box body to be in place (when moving to the left, it resets and waits for the next operation), so that when the lifting and pressing paper pasting member 31 descends, it can accurately press the surface paper, and after completion.

[0045] In addition to manually placing the paper box body at the first station 1, a lifting and translating suction and placement box putting member 11 (such as configured with a cylinder, a linear module, etc. for lifting and longitudinal translation) can also be arranged at the first station 1, which can cooperate to suck and lift the paper box body on the feeding belt and then translate it to the first station 1 to descend and release. On the left and right sides of the first station 1, there are respectively arranged box body positioning members 10 (such as side push gauges or side guide gauges, etc.), so that the relative positions of the paper box bodies are in a unified preset position for subsequent operations, and the subsequent operations are more accurate and more convenient.

[0046] Referring to the accompanying drawings, in the embodiment of the present embodiment, the folding and scraping device 50 of the carton folding machine includes a scraping component 51, a lateral limit gauge 52 and a lateral pressing and folding and abutting component 53; the front side of the fourth station 5 is the longitudinal output side of the box body, and the rear side of the fourth station 5 is the longitudinal input side of the box body, that is, the carton body 90 to be processed is input from the rear side and output from the front side, and stops at the fourth station 5 to complete the folding and scraping processing; wherein, the lateral limit gauge 52 is arranged on the left side of the fourth station 5, and when the carton is sent to the fourth station 5, the limit gauge is used to limit the position on the left side to ensure that during the subsequent scraping, the carton is in a relatively accurate position for scraping, and can cooperate with the lateral pressing and folding and abutting component 53 to clamp the carton left and right to keep the relative position of the carton stable, and cooperate with the lateral pressing and folding and abutting component 53 to smoothly operate to implement the pressing and folding and abutting operation (i.e. folding); wherein, the lateral pressing and folding and abutting component 53 is arranged on the right side of the fourth station 5, and the lateral limit gauge 52 is used to limit the position of the carton left and right to ensure that the carton is in a relatively accurate position for scraping, and can cooperate with the lateral pressing and folding and abutting component 53 to clamp left and right to keep the relative position of the carton stable, and cooperate with the lateral pressing and folding and abutting component 53 to smoothly operate to implement the pressing and folding and abutting operation (i.e. folding); wherein, the lateral pressing and folding and abutting component 53 is arranged on the right side of the fourth station 5, and the lateral limit gauge 52 is used to limit the position of the carton left and right to ensure The lateral pressing and folding abutting component 53 is transmission-connected with the abutting advancing and retreating driving component 54, and the abutting advancing and retreating driving component 54 cooperates to drive the lateral pressing and folding abutting component 53 to move back and forth to implement the pressing and folding abutting operation. The lateral pressing and folding abutting component 53 is used to fold the upper part of the side wall on the right side of the paper box (i.e., the box wall, the inner and outer surfaces of the box body of the box wall are covered with facial paper) downward and press it against the outside (i.e., the folded edge) of the lower part 91 of the box wall, and keep the upper part 92 and the lower part 91 in an abutting state to ensure the relative position is stable for subsequent scraping operations and to ensure the scraping quality. At this time, the area (end face) between the upper part 92 and the lower part 91 of the box wall is fully unfolded for scraping; wherein, the scraping component 51 is arranged on the upper side of the fourth station 5, and the scraping component 51 is transmission-connected with the scraping lifting and longitudinal movement driving component 57, and the scraping lifting and longitudinal movement driving component 57 cooperates to drive the scraping component 51 to lift and move (front and back) longitudinally to cooperate with the scraping operation and return.

[0047] Its working principle is: after the paper box body is input and stays at the fourth station 5, the lateral pressing and folding abutting component 53 folds the upper part 92 of the box wall (with facial tissue on the surface) on the right side of the paper box downward and presses it against the outside of the lower part 91 of the box wall, and keeps the upper and lower parts in abutting state. At this time, the area (end face) between the upper and lower parts of the box wall is fully unfolded, the scraping component 51 descends to contact and press the area, and the scraping component 51 moves longitudinally to scrape the facial tissue and the area (that is, the top end surfaces of the upper and lower parts of the box wall at this time) tightly.

[0048] The folding and scraping device 50 of the paper box folding machine can cooperate in making the folded edges of the paper box. The (divided) area position 94 between the upper and lower parts of a box wall of the paper box can be tightly attached to the surface paper. The surface paper in this area fits more tightly with the end faces of the upper and lower parts of the box wall (cardboard), and bulging is less likely to occur. This area (the area between the upper and lower parts of the box wall) is relatively neater, thereby improving the quality of the paper box.

[0049] For example, the lateral position-limiting gauge 52 is also drivingly connected to a left-right transverse side-pushing driving component 55 (such as a cylinder or a motor, etc.). The left-right transverse side-pushing driving component 55 cooperates to drive the lateral position-limiting gauge 52 to move horizontally left and right, so as to achieve horizontal side-pushing and horizontal return. The horizontal movement of the lateral position-limiting gauge 52 can actively side-push the carton box body for cooperation in position-limiting, and after retracting, it can be separated from the carton box body, facilitating the input and output of the carton box body.

[0050] Among them, the abutting advancing and retracting driving component 54 can drive the lateral material-pressing folding and abutting component 53 to perform reciprocating actions of obliquely advancing and retracting from high to low, or can also adopt a reciprocating action mode combining lifting and horizontal movement. For example, the abutting advancing and retracting driving component 54 includes a downward pressing and lifting driving part 58 (such as a cylinder, etc.) and a lateral pressing and horizontal movement driving part 59 (such as a cylinder, etc.), which can cooperate to drive the lateral material-pressing folding and abutting component 53 to lift up and down and move horizontally left and right. For example, the lateral pressing and horizontal movement driving part 59 is connected to a first mounting plate 591, the lateral pressing and horizontal movement driving part 59 drives the first mounting plate 591 to move horizontally left and right, the downward pressing and lifting driving part 58 is arranged on the first mounting plate 591, the downward pressing and lifting driving part 58 is connected to a second mounting plate 581, the downward pressing and lifting driving part 58 drives the second mounting plate 581 to lift and lower on the first mounting plate 591, and the lateral material-pressing folding and abutting component 53 is connected and installed on the second mounting plate 581, and even its vertical position on the second mounting plate 581 can be adjusted or the specifications can be replaced, etc.; among them, when the lateral material-pressing folding and abutting component 53 descends, the upper part of the box wall is turned and folded downward, and then the lateral material-pressing folding and abutting component 53 moves horizontally (to the left) to press the (downward-turned and folded) upper part against the lower part of the box wall, keeping the upper part and the lower part in abutment. After the corrugating is completed, the lateral material-pressing folding and abutting component 53 moves horizontally (to the right) to retract and rises to retract; it is relatively more stable and not prone to relative position movement deviation between the upper part and the lower part, and each box is relatively unified after being manufactured. For example, the lateral material-pressing folding and abutting component 53 can adopt a material-pressing folding and abutting rod or a material-pressing folding and abutting plate, etc.

[0051] The corrugating lifting and longitudinal movement driving component 57 cooperates to drive the corrugating component 51 to lift and (front and back) longitudinally move for corrugating operation and return. For example, the corrugating lifting and longitudinal movement driving component 57 includes a corrugating lifting driving part 571 and a corrugating longitudinal movement driving component 572. For example, the corrugating longitudinal movement driving component 572 adopts a linear movement module. The corrugating longitudinal movement driving component 572 is connected to an assembly frame 573. The assembly frame 573 is driven by the corrugating longitudinal movement driving component 572 to move longitudinally back and forth. The corrugating lifting driving part 571 (such as a cylinder, etc.) is installed on the assembly frame 573, and the corrugating component 51 is drivingly connected to the corrugating lifting driving part 571. The corrugating lifting driving part 571 cooperates to drive the corrugating component 51 to lift and lower on the assembly frame 573.

[0052] For another example, the scraping component 51 includes a scraping blade or a scraping brush, and the scraping blade is made of a rubber sheet; the scraping brush or the rubber sheet scrapes the edges relatively closely, and is not easy to damage the material of the paper box body, and the facial paper and the cardboard are more tightly. Among them, the lower end of the scraping blade can be a curved end, such as an arc end face, which is smooth when contacting the box body and is not easy to cause damage to the paper box body.

[0053] Normally, the upper part of the box wall on the right side of the paper box body has been folded downward, but due to the characteristic of the cardboard paper that it will rebound and open after being folded, the upper part of the box wall is easy to bend back and recover upward, affecting the subsequent (normal operation of the lateral pressing material folding and abutting component 53) operation, and the stability is poor; for this reason, an additional box wall upper part downward pre-folding guide component 56 can be further configured on the right side of the longitudinal input side of the box body at the rear side of the fourth station 5 to ensure that the upper part of the box wall is in a downward folded state in advance, and even if it rebounds and opens, it is limited to a certain range, and does not affect or interfere with the lateral pressing material folding. The folding and abutting component 53 operates normally; even, the side pressing material folding and abutting component 53 in a high position is connected with the upper part of the box wall downward pre-folding guide component 56 front to back, that is, the upper part of the box wall of the paper box body after passing through the upper part of the box wall downward pre-folding guide component 56 is in a downward folded state and directly connected to the bottom of the side pressing material folding and abutting component 53, thereby improving the working stability of the side pressing material folding and abutting component 53, smoothly completing the pressing material folding and abutting operation, and avoiding the upper part of the box wall being in an upward state, resulting in the subsequent inability to be smoothly and stably operated by the side pressing material folding and abutting component 53.

[0054] For example, the upper part of the box wall can be pre-folded downwardly by a guide plate or a guide rod. The ...

[0055] The box body longitudinal conveying device can be arranged between the lateral limit gauge 52 and the lateral material pressing folding and abutting component 53. In addition, the box wall upper part pre-folding downward guide component 56 can be arranged on the right side of the box body longitudinal conveying device 6, and cooperate with each other to fold the upper part of the box wall on the right side of the paper box downward in advance in the process of the paper box body being transferred and conveyed by the longitudinal conveying device, so as to be in a downward folded state (that is, completely turned outward) in advance.
