[0002] In the packaging and printing industry, the application of the box gluing machine is the last step in the packaging box processing. It is to fold the printed and die-cut cardboard into shape and glue the edges. The machine box gluing replaces the manual box gluing method, reducing labor costs and improving efficiency.
[0003] Existing folder gluing machines generally include a paper feeding mechanism, a correction mechanism, a pre-folding mechanism, a bottom hook mechanism, a main folding mechanism and an output mechanism. The paper feeding mechanism generally adopts friction feeding. The cardboard is placed on the conveyor belt. The distance between the front stop and the conveyor belt is only enough for one layer of cardboard to pass through. This paper feeding method is fast and efficient.
[0004] However, in the prior art, sometimes it is necessary to feed paper with less friction. In this case, the paper is prone to slipping or paper feeding fails due to paper not being in place, resulting in paper feeding interruption and affecting production efficiency.
[0005] In view of this, the utility model aims to provide a paper feeding and pressing mechanism, which, through ingenious structural design, can press the stacked papers when the paper feeding mechanism feeds paper, thereby preventing paper feeding failure caused by excessive slippage of paper or paper not being in place, thereby improving paper feeding efficiency. Moreover, the paper pressing mechanism can automatically return to its position after pressing the corresponding paper, and press the next stack of paper, with a high degree of automation. Utility Model Content
[0006] The purpose of the utility model is to provide a paper feeding and pressing mechanism to address the deficiencies of the prior art. The paper feeding and pressing mechanism can press the stacked papers through an ingenious structural design when the paper feeding mechanism is feeding the papers, thereby preventing the paper feeding failure caused by the paper being too slippery or not being in place, and improving the paper feeding efficiency. Moreover, the paper pressing mechanism can automatically return to its position after pressing the corresponding paper, and press the next stack of papers, and has a high degree of automation.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] A paper feeding and pressing mechanism comprises a connecting block, upper and lower cylinders, left and right cylinders and a pressing plate, wherein the connecting block is connected to the upper and lower cylinders, the free ends of the pistons of the left and right cylinders are connected to the pressing plate, and the pressing plate is inserted into the connecting block.
[0009] As an improvement of the paper feeding and pressing mechanism of the utility model, a slide groove is arranged on the side of the upper and lower cylinders, an upper magnetic sensor and a lower magnetic sensor are arranged in the slide groove, and the upper and lower cylinders are provided with magnets.
[0010] As an improvement of the paper feeding and pressing mechanism of the utility model, the connecting block includes a horizontal block and a vertical plate arranged perpendicular to the horizontal block, the vertical plate is connected to the upper and lower cylinders, and the horizontal block is provided with a through hole for the pressing sheet to pass through.
[0011] As an improvement of the paper feeding and pressing mechanism of the utility model, the left and right cylinders are arranged on the transverse block, and the end surfaces of the left and right cylinders are fixed to the end surface of the transverse block through a fixing block.
[0012] As an improvement of the paper feeding and pressing mechanism of the utility model, the pressing plate is L-shaped, including a horizontal portion and a vertical portion, the horizontal portion is inserted into the connecting block, and the vertical portion is connected to the free ends of the left and right cylinders.
[0013] As an improvement of the paper feeding and pressing mechanism of the utility model, buffer components are arranged at both upper and lower ends of the upper and lower cylinders.
[0014] As an improvement of the paper feeding and pressing mechanism of the utility model, a first air inlet and outlet is provided on the buffer assembly located at the upper ends of the upper and lower cylinders.
[0015] As an improvement of the paper feeding and pressing mechanism of the utility model, second air inlets and outlets are provided on the left and right air cylinders.
[0016] As an improvement of the paper feeding and pressing mechanism of the utility model, a hanging installation assembly is arranged on the back of the upper and lower cylinders.
[0017] Compared with the prior art, the utility model can press the stacked paper when the paper feeding mechanism feeds paper through a clever design, so as to prevent paper feeding failure caused by excessive slippage of paper or paper not being in place, and improve the paper feeding efficiency. Moreover, the paper pressing mechanism can automatically return to its position after pressing the corresponding paper, and press the next stack of paper, so that the degree of automation is high. At the same time, due to the setting of the left and right cylinders, the pressing plate can be retracted in the process of returning upward, so that when the paper is stacked upward again in the process of pressing the paper, the upper and lower cylinders can move upward with the retracted pressing plate, so as not to scratch the paper. When the position of the topmost paper is reached, the left and right cylinders extend the pressing plate again, press the topmost paper, and press the paper. In this way, there is no need to wait for a whole stack of paper to be fed before adding paper, but paper can be added while feeding, so as to improve the paper feeding efficiency under the premise of ensuring the paper feeding effect.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components under a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0026] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them.

[0027] like Figures 1 to 6As shown, the utility model provides a paper feeding and pressing mechanism, including a connecting block 1, an upper and lower cylinder 2, a left and right cylinder 3 and a pressing plate 4, wherein the connecting block 1 is connected to the upper and lower cylinders 2, and the free ends of the pistons of the left and right cylinders 3 are connected to the pressing plate 4, and the pressing plate 4 is inserted into the connecting block 1. The upper and lower cylinders 2 can drive the pressing plate 4, the left and right cylinders 3 and the connecting block 1 to move up and down together, and the extension and contraction of the left and right cylinders 3 can drive the extension and contraction of the pressing plate 4. When stacking paper upwards in the process of pressing paper, the upper and lower cylinders 2 can move upwards with the retracted pressing plate 4, so as not to scratch the paper. When the position of the topmost paper is reached, the left and right cylinders 3 extend the pressing plate 4 again, press the topmost paper, and perform the paper pressing operation. In this way, there is no need to wait for a whole stack of paper to be fed before adding paper, but paper can be added while feeding, thereby improving the paper feeding efficiency under the premise of ensuring the paper feeding effect.
[0028] A slide groove 5 is arranged on the side of the upper and lower cylinders 2, and an upper magnetic sensor (upper limit) and a lower magnetic sensor (lower limit) are arranged in the slide groove 5. The upper and lower cylinders 2 are provided with magnets. When the upper and lower cylinders 2 reach the bottom, the lower magnetic sensor senses the magnet and stops moving or moves upward. Similarly, when the upper and lower cylinders 2 reach the top, the upper magnetic sensor senses the magnet and stops moving or moves downward.
[0029] The connecting block 1 includes a transverse block 11 and a vertical plate 12 vertically arranged with respect to the transverse block 11. The vertical plate 12 is connected with the upper and lower cylinders 2, so as to realize the connection between the connecting block 1 and the upper and lower cylinders 2. The transverse block 11 is provided with a through hole 111 for the pressing sheet 4 to pass through, and the through hole 111 can provide space for the pressing sheet 4 to extend or retract.
[0030] The left and right cylinders 3 are arranged on the cross block 11, specifically placed in an L-shaped space formed by the cross block 11 and the vertical plate 12, and the end faces of the left and right cylinders 3 are fixed to the end faces of the cross block 11 through the fixing block 6 to achieve a fixed connection between the left and right cylinders 3 and the connecting block 1.
[0031] The pressing plate 4 is L-shaped, including a horizontal portion 41 and a vertical portion 42. The horizontal portion 41 is inserted into the connecting block 1, and the vertical portion 42 is connected to the free ends of the left and right cylinders 3, so that when the piston rods of the left and right cylinders 3 move left and right, the pressing plate 4 can be driven to move left and right.
[0032] Buffer components 21 are provided at both upper and lower ends of the upper and lower cylinders 2 to provide buffer force for the collision of the upper and lower cylinders 2 .
[0033] The buffer assembly 21 located at the upper end of the upper and lower cylinders 2 is provided with a first air inlet and outlet 211 for supplying air to the upper and lower cylinders 2 to achieve the up and down movement of the upper and lower cylinders 2 .
[0034] The left and right cylinders 3 are provided with second air inlets and outlets for supplying air to the left and right cylinders 3 to achieve the left and right movement of the left and right cylinders 3 .
[0035] A hanging mounting assembly 7 is provided on the back of the upper and lower cylinders 2 for fixing the entire paper feeding and pressing mechanism into the paper feeding mechanism.
[0036] In short, the utility model can press the stacked paper when the paper feeding mechanism feeds paper through a clever design, so as to prevent the paper feeding failure caused by the paper slipping too much or the paper not being in place, and improve the paper feeding efficiency. Moreover, the paper pressing mechanism can automatically return to its position after pressing the corresponding paper, and press the next stack of paper, so that the degree of automation is high. At the same time, due to the setting of the left and right cylinders 3, the pressing plate 4 can be retracted in the process of returning upward, so that when the paper is stacked upward again in the process of pressing the paper, the upper and lower cylinders 2 can move upward with the retracted pressing plate 4, so as not to scratch the paper. When the position of the topmost paper is reached, the left and right cylinders 3 extend the pressing plate 4 again, press the topmost paper, and perform the paper pressing operation. In this way, there is no need to wait for a whole stack of paper to be fed before adding paper, but paper can be added while feeding, so as to improve the paper feeding efficiency under the premise of ensuring the paper feeding effect.
[0037] According to the disclosure and teaching of the above description, the technicians in the field of the utility model can also make appropriate changes and modifications to the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
