Description

Technical Field

[0001] The utility model relates to paper box making, in particular to a scraping device of a paper box folding machine. Background Art

[0002] There are many structures of paper boxes (such as cover boxes, bottom boxes, drawer boxes, etc.). For example, when producing a paper box such as a cover box, one side wall of the box body is divided into an upper part and a lower part (such as by grooves, indentations, or segmentation), and the surface of the side wall is also pasted with face paper (the face paper has been pre-glued, such as a rubber roller), so that the upper cardboard part can be folded outward relative to the lower cardboard part, wherein the face paper is not only pasted on the outside of the box body of the side wall, but also on the inside of the box body of the side wall, and even on the dividing area between the upper and lower parts of the side wall. The pasted face paper outside the dividing area is very likely to bulge, which is not tight and flat, affecting the quality of the paper box. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the utility model aims to provide a scraping device for a paper box folding machine which can avoid bulging and improve the quality of the paper box.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions: a scraping device of a paper box folding machine is arranged at a scraping station, and is characterized in that it includes a scraping component, a lateral limit gauge and a lateral material pressing and folding component. The front side of the scraping station is the longitudinal output side of the box body, and the rear side of the scraping station is the longitudinal input side of the box body. The lateral limit gauge is arranged on the left side of the scraping station, and the lateral material pressing and folding component is arranged on the right side of the scraping station. The lateral material pressing and folding component is transmission-connected with abutting advance and retreat driving component. The scraping component is arranged on the upper side of the scraping station, and the scraping component is transmission-connected with a scraping lifting and longitudinal movement driving component.

[0005] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0006] For example, the lateral limit gauge is also transmission-connected with left and right lateral displacement and thrust driving components.

[0007] For example, the advancing and retreating driving components include a downward pressing and lifting driving component and a sideways pressing and lateral moving driving component.

[0008] For example, the scraping component includes a scraping blade or a scraping brush, and the scraping blade is a rubber blade. Further optimization, the lower end of the scraping blade is a curved surface end.

[0009] For further optimization, a side wall upper portion pre-folding guide component is also provided on the right side of the longitudinal input side of the box body at the rear side of the scraping station; the high-positioned lateral pressing and folding abutting component is connected front to back with the side wall upper portion pre-folding guide component.

[0010] For another example, the guiding component that is pre-folded downward at the upper part of the side wall adopts a guiding plate or a guiding rod. In addition, the guiding plate and the guiding rod are arranged with adjustable relative vertical height positions. For example, the guiding component that is pre-folded downward at the upper part of the side wall has a guiding setting with a lower height at the back and a higher height at the front.

[0011] In addition, for supplementary optimization, a longitudinal conveying device for the box body is connected to the corrugating station, and the guiding component that is pre-folded downward at the upper part of the side wall is arranged on the right side of the longitudinal conveying device for the box body.

[0012] The beneficial effects of the present utility model are as follows: after the paper box body is input and stays at the corrugating station, the lateral pressing and folding and adhering component folds the upper part of the side wall (with the face paper pasted on the surface) on the right side of the paper box downward and presses it against the outer surface of the lower part of the side wall, and keeps the upper part and the lower part in an adhering state. At this time, the area (end face) between the upper part and the lower part of the side wall is completely unfolded. The corrugating component descends to contact and press this area, and the corrugating component moves longitudinally to perform corrugating, so as to scrape the face paper and this area (that is, the top end faces of the upper part and the lower part of the side wall at this time) tightly. The corrugating device of this paper box folding machine can cooperate with the production of paper box folding. The area (division) between the upper part and the lower part of one side wall of the paper box can be tightly adhered to the face paper. The face paper is more tightly adhered to the end faces of the upper part and the lower part (paperboard) of the side wall in this area, and it is not easy to have bulging. This area (the area between the upper part and the lower part of the side wall) is relatively neater, improving the quality of the paper box. Description of the Drawings

[0022] 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 implementation manner of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0023] Referring to the accompanying drawings, in the embodiment of the present embodiment, the scraping device 50 of the carton folding machine is arranged at the scraping station 5, and the scraping device 50 includes a scraping component 51, a lateral limit gauge 52 and a lateral material pressing and folding component 53; the front side of the scraping station 5 is the longitudinal output side of the box body, and the rear side of the scraping station 5 is the longitudinal input side of the box body, that is, the carton box body 90 to be scraped is input from the rear side and output from the front side, and the scraping is completed at the scraping station 5. Processing; wherein, the lateral limit gauge 52 is arranged on the left side of the scraping station 5. When the carton is sent to the scraping station 5, the limit gauge cooperates with the limit on the left side to ensure that the carton is in a relatively accurate position for scraping in the subsequent scraping, and can cooperate with the lateral pressing material folding and abutting component 53 to clamp the carton on the left and right to keep the relative position of the carton stable, and cooperate with the lateral pressing material folding and abutting component 53 to smoothly operate and implement the pressing material folding and abutting operation; wherein, the lateral pressing material folding and abutting component 53 The lateral pressing and folding abutting component 53 is arranged on the right side of the scraping station 5, and is connected to 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 (the inner and outer surfaces of the box body are pasted with facial paper) downward and press it against the outside of the lower part 91 of the side 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 of the side wall is fully unfolded for scraping; wherein, the scraping component 51 is arranged on the upper side of the scraping station 5, and the scraping component 51 is connected to 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.

[0024] Its working principle is: after the paper box body is input and stays in the scraping station 5, the lateral pressing and folding abutting component 53 folds the upper part of the side wall (with facial paper on the surface) on the right side of the paper box downward and presses it against the outside of the lower part of the side 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 side 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 paper and the area (that is, the top end surfaces of the upper and lower parts of the side wall at this time) are scraped tightly.

[0025] The scraping device 50 of the paper box folding machine can cooperate in making the folded edges of the paper box. The (divided) area between the upper and lower parts of one side wall of the paper box can be tightly attached to the surface paper. The surface paper in this area is more tightly attached to the end faces of the upper and lower parts of the side wall (cardboard), and bulging is less likely to occur. This area (the area between the upper and lower parts of the side wall) is relatively neater, thereby improving the quality of the paper box.

[0026] Based on the above embodiments, the following optimizations or further explanations can be made respectively.

[0027] For example, the lateral limiting gauge 52 is also drivingly connected to a left - right transverse pushing drive member 55 (such as a cylinder or a motor, etc.). The left - right transverse pushing drive member 55 cooperates to drive the lateral limiting gauge 52 to move left - right transversely, realizing transverse pushing and transverse retracting. The left - right transverse movement of the lateral limiting gauge 52 can actively laterally push the carton box body for cooperation in limiting, and after retracting, it can be separated from the carton box body, facilitating the input and output of the carton box body.

[0028] Among them, the abutting advancing - retreating drive member 54 can drive the lateral pressing and folding abutting member 53 to perform an inclined advancing - retreating reciprocating motion from high to low, or can also adopt a reciprocating motion mode combining lifting and transverse movement. For example, the abutting advancing - retreating drive member 54 includes a downward - pressing lifting drive member 58 (such as a cylinder, etc.) and a lateral - pressing transverse movement drive member 59 (such as a cylinder, etc.), which can cooperate to drive the lateral pressing and folding abutting member 53 to lift up and down and move left - right transversely. For example, the lateral - pressing transverse movement drive member 59 is connected to a first mounting plate 591, the lateral - pressing transverse movement drive member 59 drives the first mounting plate 591 to move left - right transversely, the downward - pressing lifting drive member 58 is arranged on the first mounting plate 591, the downward - pressing lifting drive member 58 is connected to a second mounting plate 581, the downward - pressing lifting drive member 58 drives the second mounting plate 581 to lift and lower on the first mounting plate 591, and the lateral pressing and folding abutting member 53 is connected and installed on the second mounting plate 581, and even its up - down position on the second mounting plate 581 can be adjusted or the specifications can be changed, etc.; among them, when the lateral pressing and folding abutting member 53 descends, it flips and folds the upper part of the side wall downward, and then the lateral pressing and folding abutting member 53 moves (left) transversely to press the (downward - flipped and folded) upper part against the lower part of the side wall, keeping the upper part and the lower part in abutment. After the corrugating is completed, the lateral pressing and folding abutting member 53 moves (right) transversely back and rises back; it is relatively more stable and not likely to have a 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 pressing and folding abutting member 53 can adopt a pressing and folding abutting rod or a pressing and folding abutting plate, etc.

[0029] The corrugating lifting and longitudinal movement drive member 57 cooperates to drive the corrugating member 51 to lift and (front - back) longitudinally move for corrugating operation and retraction. For example, the corrugating lifting and longitudinal movement drive member 57 includes a corrugating lifting drive member 571 and a corrugating longitudinal movement drive member 572. For example, the corrugating longitudinal movement drive member 572 adopts a linear movement module, the corrugating longitudinal movement drive member 572 is connected to an assembly frame 573, the assembly frame 573 is driven by the corrugating longitudinal movement drive member 572 to move longitudinally back and forth, the corrugating lifting drive member 571 (such as a cylinder, etc.) is installed on the assembly frame 573, and the corrugating member 51 is drivingly connected to the corrugating lifting drive member 571, and the corrugating lifting drive member 571 cooperates to drive the corrugating member 51 to lift and lower on the assembly frame 573.

[0030] 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.

[0031] Normally, the upper part of the right side wall of the paper box body has been folded downward, but since the cardboard paper will rebound and open after being folded, the upper part of the side wall is easy to bend back and recover, 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 side 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 scraping station 5 to ensure that the upper part of the side 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 side wall downward pre-folding guide component 56 front to back, that is, the upper part of the side wall of the paper box body after passing through the upper part of the side 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 side 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.

[0032] For example, the side wall upper part downward pre-folding guide component 56 can be a guide plate or a guide rod, and the upper and lower height positions of the side wall upper part downward pre-folding guide component 56 can be adjusted to adapt to the requirements of paper box bodies of different specifications and sizes, and to debug and stabilize operation, and a mounting seat 561 can be provided for the upper part of the side wall downward pre-folding guide component 56 to be assembled and set. For another example, when the side wall upper part downward pre-folding guide component 56 is set, the rear side is high and the front side is low. It can be set straight and obliquely, that is, it is set obliquely, and even the angle of inclination can be adjusted to meet the requirements of different specifications and ensure smooth connection with the side pressing material folding and abutting component 53.

[0033] In addition, a longitudinal carton body conveying device 6 is connected to the corrugating station 5. The longitudinal carton body conveying device 6 cooperates to input and output the carton body to and from the corrugating station 5, facilitating the input and output of the carton body so as to form a production line. For example, a conveyor belt or a conveying fixture that longitudinally moves from back to front can have the longitudinal carton body conveying device arranged between the side limiting gauge 52 and the side pressing and folding and abutting member 53. Additionally, the upper side wall downward pre-folding guiding member 56 can be arranged on the right side of the longitudinal carton body conveying device 6. During the process of the carton body being longitudinally conveyed and transported by the longitudinal conveying device, they cooperate to pre-fold the upper part of the right side wall of the carton downward in a downward-flipped state in advance.
