Description

Technical Field

[0001] This utility model relates to the field of paperboard processing technology, specifically to an auxiliary device for coating paperboard surfaces. Background Technology

[0002] A cardboard surface coating device is a device used to uniformly coat the surface of cardboard with glue. It is mainly used in packaging, printing, furniture manufacturing and other fields, and improves production efficiency and coating quality through automated or semi-automated operation.

[0003] When applying glue to the surface of a cardboard box, the flat, folded cardboard is placed on the workbench and then conveyed to the glue applicator by a conveyor belt. However, due to environmental factors during storage, the cardboard may have curled edges or curled up. During the glue application process, this may result in uneven glue distribution, insufficient edge adhesion, and missed areas, thus affecting the quality of the cardboard. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for coating the surface of cardboard, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardboard surface coating auxiliary device, including a fixed frame, a glue applicator fixedly connected to the top of the fixed frame, a conveyor belt installed on the fixed frame, and further comprising:

[0006] A connecting frame is fixedly connected to the glue applicator. A connecting sleeve is installed on the connecting frame, a connecting rod is installed on the connecting sleeve, a limit wheel is installed on the connecting rod, and an adjustment component for adjusting the angle of the limit wheel is installed on the connecting sleeve.

[0007] The holding components are provided in two sets and are symmetrically installed on the fixed frame.

[0008] Preferably, the adjusting assembly includes a mounting base fixedly connected to the connecting sleeve, a connecting rod rotatably connected to the mounting base, a worm gear rotatably connected to the mounting base, and a worm wheel connected to the connecting rod via a rotating shaft.

[0009] Preferably, a screw is inserted into the connecting sleeve, and a screw hole is provided on the connecting frame.

[0010] Preferably, the pressing assembly includes a lead screw rotatably mounted on a fixed frame, a connecting seat threaded onto the outer side of the lead screw, a pressure rod fixedly connected to the connecting seat, and a turntable fixedly connected to the lead screw.

[0011] Preferably, a fixing rod is fixedly connected to the fixing frame, and a sliding groove is provided on the connecting seat, which slides on the outside of the fixing rod through the sliding groove.

[0012] Preferably, a number of rollers are installed at the bottom of the pressure bar.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention adjusts the limiting wheel and pressure bar to the appropriate position according to the size of the cardboard. The cardboard is then conveyed to the glue coating machine via a conveyor belt. If the cardboard has curled edges, the curled edges enter the lower part of the pressure bar and roll with the roller. As the cardboard moves gradually and the rear of the pressure bar gradually becomes horizontal, the curled edges of the cardboard are pressed down and flattened. At the same time, the limiting wheel presses the curled edges of the cardboard downward, so that it is in a flat state when it enters the glue coating machine. This avoids uneven glue distribution, insufficient edge adhesion, and missed coating in some areas caused by the curled edges of the cardboard. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, a cardboard surface coating auxiliary device includes a fixed frame 1. A glue applicator 2 is fixedly connected to the top of the fixed frame 1. The glue applicator 2 is a prior art technology, consisting of multiple rollers (glue applicator roller, glue transfer roller, glue extrusion roller, etc.). Glue application is completed through the rotation and pressure of the rollers. The glue is evenly transferred to the surface of the glue applicator roller through the glue transfer roller. The cardboard passes between the glue applicator roller and the glue extrusion roller, and the glue is pressed onto the surface of the cardboard. Its application scenario is the same as the prior art. A conveyor belt 3 is installed on the fixed frame 1. The conveyor belt 3 is also a prior art technology, which includes transmission equipment and transmission rollers, etc., with specific structure... Without going into detail here, the component used for transporting cardboard also includes: a connecting frame 4, which is fixedly connected to the glue coater 2. A connecting sleeve 5 is installed on the connecting frame 4, and a connecting rod 6 is installed on the connecting sleeve 5. A limit wheel 7 is installed on the connecting rod 6. The limit wheel 7 is rotatably mounted on the connecting rod 6 and can press and limit the cardboard. An adjusting component 8 is installed on the connecting sleeve 5 to adjust the angle of the limit wheel 7. The pressing angle of the limit wheel 7 can be adjusted by the adjusting component 8. Two sets of pressing components 9 are provided and symmetrically installed on the fixed frame 1. The flatness of the cardboard is adjusted by the synchronous cooperation between the pressing components 9 and the limit wheel 7.

[0024] It should be noted that: the cardboard is conveyed to the glue coating machine 2 by the conveyor belt 3. Before the cardboard is fed into the glue coating machine for glue treatment, the corners of the cardboard can be flattened by the limit wheel 7 and the pressing component 9 to prevent the cardboard from curling up during glue coating and affecting the glue coating effect.

[0025] The adjusting assembly 8 includes a mounting base 801 fixedly connected to the connecting sleeve 5, a connecting rod 6 rotatably connected to the mounting base 801, a worm gear 802 rotatably connected to the mounting base 801, and a worm wheel 803 connected to the connecting rod 6 via a rotating shaft. One end of the connecting rod 6 is fixedly connected to a rotating shaft, which is rotatably connected to the mounting base 801. The worm wheel 803 is fixed to the rotating shaft and meshes with the worm gear 802. Rotating the worm gear 802 drives the meshing worm wheel 803 to rotate, which in turn drives the rotating shaft on the connecting rod 6. The connecting rod 6 rotates synchronously in the mounting base 801, thereby allowing adjustment of the angles of the connecting rod 6 and the limiting wheel 7. A screw 12 is inserted into the connecting sleeve 5, and a screw hole 13 is provided on the connecting frame 4. By moving the connecting sleeve 5 on the connecting frame 4, the connecting rod 6 is moved to a suitable position, and the insertion hole on the connecting sleeve 5 corresponds to the screw hole 13 on the connecting frame 4. Then, the screw 12 is passed through the connecting sleeve 5 and the screw hole 13, which can fix the connecting sleeve 5 on the connecting frame 4, thereby adjusting the two limiting wheels 7 to a suitable distance.

[0026] The pressing assembly 9 includes a lead screw 901 rotatably mounted on a fixed frame 1, a connecting seat 902 threaded onto the outer side of the lead screw 901, a pressing rod 903 fixedly connected to the connecting seat 902, and a turntable 904 fixedly connected to the lead screw 901; a fixed rod 10 is fixedly connected to the fixed frame 1, and a sliding groove 11 is provided on the connecting seat 902, allowing the connecting seat 902 to slide on the outer side of the fixed rod 10 via the sliding groove 11; the lead screw 901 is rotated by the turntable 904, causing the lead screw 901 to thread onto the connecting seat 902. The cardboard is connected by a fixed rod 10, which limits the connection seat 902, causing the connection seat 902 to drive the pressure rod 903 to move vertically up and down, adjusting the pressure rod 903 to a suitable height. Several sets of rollers 14 are installed at the bottom of the pressure rod 903. The end of the pressure rod 903 that is farther away from the connection seat 902 is tilted upward. After the tilted edge of the cardboard enters the lower part of the pressure rod 903, it rolls with the rollers 14. As the cardboard moves gradually, and the rear of the pressure rod 903 gradually becomes horizontal, the tilted edge of the cardboard is pressed down and flattened.

[0027] Working principle: Adjust the limiting wheel 7 and pressure bar 903 to the appropriate positions according to the size of the cardboard. The cardboard is conveyed to the glue coater 2 by the conveyor belt 3. If the cardboard has curled edges, the curled edges will enter the lower part of the pressure bar 903 and roll with the roller 14. As the cardboard moves gradually and the rear of the pressure bar 903 gradually becomes horizontal, the curled edges of the cardboard are pressed down and flattened. At the same time, the limiting wheel 7 presses the curled edges of the cardboard downward, so that it is in a flat state when it enters the glue coater 2. This avoids uneven glue distribution, insufficient edge adhesion and some missed coating caused by the curled edges of the cardboard.
