Description

Technical Field

[0001] The utility model relates to the technical field of corrugated board production equipment, in particular to a fast-switching paper pressing mechanism. Background Art

[0002] In the corrugated cardboard production line, the gluing machine (glue coating machine) is a very important equipment. The function of the gluing machine is to apply adhesive to the corrugated cardboard to make it stronger, so as to better complete the bonding on the double-sided machine to form corrugated cardboard.

[0003] The various components of the entire corrugated cardboard production line are closely related. When the corrugator changes paper or orders, different base papers of different grammage will be replaced to adapt to different orders. Conventional gluing machines are generally only equipped with a press roller or a contact pressure bar to press the paper, which cannot adapt to the production of diversified orders. In addition, the existing press roller / contact pressure bar relies on two end plates for operation. The end plates are not rigid enough and are easy to bend, which in turn affects the accuracy of gluing and the quality of the cardboard. Utility Model Content

[0004] The purpose of the utility model is to overcome the above-mentioned defects in the prior art, provide a fast-switching paper pressing mechanism, and switch the gluing and pressing mode of the gluing machine with one button to adapt to different materials of base paper for different orders, improve the gluing quality of single-wall paper, optimize production, and reduce glue loss.

[0005] To achieve the above-mentioned purpose, the present invention provides a fast-switching paper pressing mechanism, comprising:

[0006] Two end plates are symmetrically arranged, a paper guide roller is arranged between the two end plates, and a reinforcement piece is arranged between the two end plates;

[0007] A paper feed guide roller, wherein the other ends of the two end plates away from the paper discharge guide roller are hung on the paper feed guide roller, and a height difference is formed between the paper discharge guide roller and the paper feed guide roller;

[0008] A switching assembly is provided on the end plate, the switching assembly comprising a switching cylinder fixedly provided on the end plate and a transmission member rotatably provided on the inner side of the end plate, the transmission member being respectively connected to a paper pressing roller and a touch pressure rod, the paper pressing roller and the touch pressure rod being placed between the paper feed guide roller and the paper discharge guide roller;

[0009] A water spray pipe is provided between the two end plates, and the water spray pipe is adjacent to the paper feed guide roller.

[0010] Furthermore, the reinforcement has an L-shaped cross-section and is evenly distributed with multiple angle bars. Each angle bar has a guide slope facing the paper pressing roller and contact pressure bar. The angle bars increase the strength of the reinforcement, improving structural performance. The guide slopes also provide support for the corrugated paper, increasing its straightness during gluing and resulting in a more effective gluing process.

[0011] Furthermore, the paper feed guide roller is movably connected to a first flange bearing and a second flange bearing at each end. The undersides of the two end plates are provided with a mounting slot, which is mounted on the first flange bearing. The second flange bearing allows the paper feed guide roller to be mounted on the gluing machine and rotated. The first flange bearing cooperates with the mounting slot to achieve mounting of the end plates without affecting the free rotation of the paper feed guide roller.

[0012] Furthermore, a limit seat is provided at one end of the end plate, and an outwardly extending limit block is provided inside the limit seat. The limit block is provided with an inclined top surface. The limit seat can limit the transmission member, allowing it to interact within a predetermined path, achieving directional rotation to facilitate precise switching of the touch pressure rod and paper pressing roller. In particular, the provision of the limit block can enhance the structural strength of the limit seat and increase its overall stability.

[0013] Furthermore, the transmission member has an overall triangular structure, with the paper pressing roller, contact pressure rod, and switching cylinder respectively connected to the three ends of the transmission member. A third flange bearing is provided on the end plate, and the middle portion of the transmission member is connected to the third flange bearing to achieve rotation. The triangular structure of the transmission member ensures a good travel distribution when the switching cylinder drives the rotation, facilitating that the paper pressing roller or contact pressure rod can accurately reach the operating position after switching.

[0014] Furthermore, the switching cylinder is connected to one side of the transmission member, and the other side of the transmission member is connected to a cylindrical reinforcement rib. The cylindrical reinforcement rib can increase the stability of the connection between the end plates and prevent deformation.

[0015] Furthermore, both ends of the paper pressing roller are rotatably connected to the transmission member via bearings, thereby enabling the paper pressing roller to rotate freely.

[0016] Furthermore, the other end of the end plate, away from the paper feed guide roller, extends downwardly and tilted to form an inclined arm, and the paper discharge guide roller is mounted on the inclined arm, so that the paper discharge guide roller and the paper feed guide roller are staggered in height, which is beneficial to the flatness of the corrugated paper during gluing and improves the gluing effect.

[0017] Furthermore, the touch-pressure rod includes a touch-pressure base and a plurality of touch-pressure blocks, the two ends of the touch-pressure base being fixedly connected to the transmission member, the touch-pressure blocks including an integrally formed elastic portion and a touch-pressure portion, the elastic portion being fixedly connected to the touch-pressure base, the inner side of the touch-pressure portion being connected to a limiter, the touch-pressure base being provided with a limiter hole, the limiter being inserted into the limiter hole, and the limiter being provided with a return spring, the return spring being interposed between the touch-pressure portion and the touch-pressure base. This enables the touch-pressure portion to contact the surface of the corrugated paper, thereby improving the gluing quality of the corrugated paper when gluing.

[0018] Furthermore, the end plate is provided with a support member inclined toward the paper feed guide roller. The water spray pipe is fixed to the support member and has multiple sets of evenly distributed water spray outlets disposed in the water spray pipe, each of which is oriented toward a position intermediate between the paper feed guide roller and the paper discharge guide roller. The water spray pipe can be used to spray water as needed, thereby adjusting the adhesive strength to meet the needs of different orders and also controlling the humidity of the corrugated paper as needed.

[0019] Compared with the prior art, the utility model has the following advantages: the utility model switches the gluing and loading mode of the gluing machine with one button to adapt to base papers of different materials for different orders, improves the gluing quality of single-wall paper, optimizes production, and reduces glue loss; at the same time, reinforcements are provided between the end plates, which can improve the stability of the components between the end plates, greatly reduce the problem of bending of the end plates, and improve the accuracy of gluing; furthermore, a water spray pipe is provided in front of the paper feed guide roller, and the water spray pipe can spray water mist on the working base paper in real time, increase the moisture content of the base paper, increase the gluing effect, and can also dilute the glue to adapt to the requirements of different base papers for glue adhesion.

[0031] See also Figures 1 to 5 , an embodiment of the utility model provides a fast-switching paper pressing mechanism.

[0032] The fast switching paper pressing mechanism of this embodiment is as follows: Figures 1 to 2 As shown, it includes two sets of symmetrically arranged end plates 1, paper feed guide rollers 2, a switching component 3 and a water spray pipe 4;

[0033] A paper discharge guide roller 5 is arranged between the two end plates 1. The paper discharge guide roller 5 can be freely rotated by means of the arranged bearings. The other end of the two end plates 1 away from the paper discharge guide roller 5 is hung on the paper feed guide roller 2. The specific hanging method is: a first flange bearing 21 and a second flange bearing 22 are movably connected in sequence at both ends of the paper feed guide roller 2. The first flange bearing 21 and the second flange bearing 22 are composed of flange embedded bearings. A hanging groove 11 is provided on the lower side of the two end plates 1. The hanging groove 11 is hung on the first flange bearing 21. After the end plate 1 is hung on the first flange bearing 21, the outer edge of the first flange bearing 21 is fixed to the four sides of the hanging groove 11 by screws and other parts.

[0034] In order to achieve a height difference between the paper discharge guide roller 5 and the paper feed guide roller 2, an inclined arm 12 is formed at the other end of the end plate 1 away from the paper feed guide roller 2, which extends downward and in the opposite direction of the paper feed guide roller 2. The paper discharge guide roller 5 is installed on the inclined arm 12, so that the paper discharge guide roller 5 and the paper feed guide are staggered in height.

[0035] The switching assembly 3 is arranged on the end plate 1, as shown in FIG. Figure 3 As shown, the switching assembly 3 in this embodiment includes a switching cylinder 31 fixed on the end plate 1 and a transmission member 32 rotatably arranged on the inner side of the end plate 1, and the transmission member 32 is respectively connected to the paper pressing roller 6 and the touch pressure rod 7. Figure 4 and Figure 5 As shown, the touch-pressure rod 7 includes a touch-pressure base 71 and a plurality of touch-pressure blocks 72. The two ends of the touch-pressure base 71 are fixedly connected to the transmission member 32, and the two ends of the paper pressing roller 6 are rotatably connected to the transmission member 32 via bearings. The touch-pressure block 72 includes an integrally formed elastic portion 721 and a touch-pressure portion 722. The elastic portion 721 is fixedly connected to the touch-pressure base 71. The inner side of the touch-pressure portion 722 is connected to a limiting member 723. A limiting hole 711 is provided on the touch-pressure base 71. The limiting member 723 is inserted into the limiting hole 711, and a return spring 724 is provided on the limiting member 723. The return spring 724 is placed between the touch-pressure portion 722 and the touch-pressure base 71.

[0036] The above-mentioned paper pressing roller 6 and touch pressure rod 7 are placed between the paper feed guide roller 2 and the paper discharge guide roller 5. Specifically, the above-mentioned transmission member 32 is a triangular structure as a whole. The paper pressing roller 6, the touch pressure rod 7 and the switching cylinder 31 are respectively connected to the three ends of the transmission member 32. In order to further improve the efficiency of the rotational force transmission, the length of one end of the above-mentioned transmission member 32 connected to the switching cylinder 31 can be set to be slightly larger than the length of the other two ends. A third flange bearing 13 is provided on the end plate 1, and the middle position of the transmission member 32 is connected to the third flange bearing 13 to achieve rotation. Furthermore, a limit seat 14 is provided at one end of the end plate 1, and a limit block 141 extending outward is provided on the inner side of the limit seat 14. The limit block 141 is provided with an inclined top connection surface, so as to play a certain limiting role on the transmission member 32 and the switching cylinder 31, providing rotation accuracy while avoiding excessive rotation stroke affecting the position of the paper pressing roller 6 and the touch pressure rod 7 after conversion and failing to glue normally.

[0037] The switching cylinder 31 drives the transmission member 32 to rotate, and it is necessary to ensure the synchronous operation of the two transmission members 32. In order to enhance the synchronization rate, the switching cylinder 31 is connected to one side of the transmission member 32, and the other side of the transmission member 32 is connected with a cylindrical reinforcement rib 33. The linkage of the cylindrical reinforcement rib can not only improve the overall structural strength, but also effectively enhance the linkage of its rotation.

[0038] The water spray pipe 4 is arranged between the two end plates 1, and the water spray pipe 4 is adjacent to the paper feed guide roller 2. The end plate 1 is provided with a support member 41 inclined toward the paper feed guide roller 2. The water spray pipe 4 is fixed to the support member 41, and multiple groups of evenly distributed water spray outlets are opened on the water spray pipe 4, and the water spray outlets are directed toward the middle position between the paper feed guide roller 2 and the paper discharge guide roller 5.

[0039] In this embodiment, in order to improve the structural rigidity between the two end plates 1, a reinforcement member 15 is provided between the two end plates 1. The cross-section of the reinforcement member 15 is "L"-shaped. A plurality of angle steel bars 151 are evenly arranged on the reinforcement member 15. The angle steel bars 151 are provided with guide slopes, which face the paper pressing roller 6 and the contact pressure bar 7.

[0040] The working principle of the present invention is briefly described as follows: The reuse of the present invention is to first fix it to the gluing machine through the second flange bearing 22, and the corrugated paper enters from the paper feed guide roller 2 and is then output from the paper pressing roller 6 and the paper discharge guide roller 5 in sequence to connect to the next process. The initial setting is that the paper pressing roller 6 works, and the corrugated paper can be fitted with the gluing roller of the gluing mechanism through the paper pressing roller 6 to realize the gluing operation. When the touch pressure rod 7 needs to be replaced for different orders, it is only necessary to start the switching cylinder 31 to rotate the transmission member 32. At this time, the paper pressing roller 6 will rise and leave the gluing operation area, and the touch pressure rod 7 will move to the operation area to press down the corrugated paper so that the corrugated paper can be glued.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
