Description

Technical Field

[0001] This utility model belongs to the technical field of gluing machines for packaging cardboard, and relates to a gluing machine for wine box packaging cardboard. Background Technology

[0002] In the preparation process of wine box packaging paper, the hard-shell packaging cardboard needs to be placed in a set position for conveying and gluing. After gluing, the outer packaging layer (decorative layer) is placed for bonding. During the gluing process, the glue needs to be pumped to the gluing roller, and the packaging cardboard is glued through the gluing roller. Usually, the glue is pumped to the roller by direct pumping. This method has the problem that if the pumping process is unstable, the amount of glue put into the gluing roller will suddenly decrease, which can easily lead to uneven gluing. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a glue-applying machine for wine box packaging cardboard, which can ensure uniform glue application to the packaging cardboard.

[0004] The technical solution adopted by this utility model is as follows: a gluing machine for wine box packaging cardboard, including a gluing roller, a drive roller, and a glue storage tank. The gluing roller and the drive roller are rotatably connected to the gluing machine frame and are tightly fitted together. The drive roller is connected to a power mechanism that drives its rotation. The power mechanism is installed on the gluing machine frame. The gluing machine frame is installed at the transition between the feeding belt conveyor and the discharge adsorption belt conveyor. The glue storage tank is installed on the gluing machine frame through a bracket. A liquid outlet pipe is provided at the bottom of the glue storage tank. The lower end of the liquid outlet pipe is directly opposite the joint between the gluing roller and the drive roller. The glue storage tank is connected to a circulation pump through a pipe. The circulation pump is connected to a recycling tank. The recycling tank is installed on the bottom surface. A recycling glue tank is provided at the bottom of the gluing roller. An inclined discharge hopper is provided at one end of the recycling glue tank. The discharge port of the inclined discharge hopper is located above the recycling tank.

[0005] Furthermore, the aforementioned outlet pipe is equipped with a valve.

[0006] Furthermore, the aforementioned gate frame includes two angle steels and two square frames. The two square frames are fixedly connected to the top surfaces of both sides of the glue application machine frame. The two angle steels are symmetrically fixedly connected to the top of the two square frames and arranged opposite to each other. The glue storage tank is inserted into the limiting slot formed by the two angle steels for limiting.

[0007] Furthermore, the belt of the aforementioned feeding conveyor is 3-5mm higher than the lowest point of the gluing roller. A pressing strip frame is installed on the upper side of the feeding conveyor. The pressing strip frame can press the wine box packaging cardboard forward and adhere it to the gluing roller and overlap it onto the discharge adsorption conveyor. The feed end of the discharge adsorption conveyor is provided with a slope, and it is located above the recycling glue tank during the gluing process of the wine box packaging cardboard.

[0008] Furthermore, the aforementioned pressing strip frame includes multiple longitudinal pressing strips and a transverse plate. The multiple longitudinal pressing strips are evenly spaced and their upper ends are fixedly connected to the transverse plate. The two ends of the transverse plate are fixedly connected to both sides of the belt frame of the feeding belt conveyor through support columns.

[0009] The beneficial effects of this utility model are as follows: Compared with the prior art, this utility model installs an adhesive storage tank in front of the adhesive outlet pipe. By storing excess adhesive in the adhesive storage tank, the adhesive can be stably discharged during the process of discharging adhesive through the outlet pipe. This avoids the problem of uneven adhesive application caused by insufficient adhesive supply due to the instability or intermittent operation of the adhesive pump. The simple circulating adhesive supply avoids and reduces losses and interruptions in the feeding process. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0014] Example 1: Refer to Figure 1-3As shown, a gluing machine for wine box packaging cardboard includes a gluing roller 1, a drive roller 2, and a glue storage tank 3. The gluing roller 1 and the drive roller 2 are rotatably connected to a gluing frame 4 and are tightly fitted together. The drive roller 2 is connected to a power mechanism that drives its rotation. The power mechanism is mounted on the gluing frame 4, which is installed at the transition point between the feeding conveyor belt 5 and the discharge suction conveyor belt 6. The glue storage tank 3 is mounted on the gluing frame 4 via a bracket 7. A liquid outlet pipe 8 is provided at the bottom of the glue storage tank 3, with the lower end of the outlet pipe 8 facing the joint between the gluing roller 1 and the drive roller 2. The glue storage tank 3 is connected to a circulation pump 9 via a pipe 10. The circulation pump 9 is mounted on the ground via a fixed bracket and is connected to a recycling bin 11, which is mounted on the bottom surface. A long strip-shaped recycling glue tank 12 with the same length direction as the gluing roller 1 is provided at the bottom of the gluing roller 1 and is opposite to the upper part of the roller. The glue rollers are symmetrically distributed along their axes. The width of the glue recovery tank 12 is more than four-fifths of the diameter of the glue application roller, ensuring that as much glue as possible falls onto the glue recovery tank 12. The glue recovery tank 12 is mounted on the glue application frame 4. One end of the glue recovery tank 12 is equipped with an inclined discharge hopper 13. The outlet of the inclined discharge hopper 13 is located above the recovery tank 11. The glue recovery tank 12 is inclined towards the inclined discharge hopper, which is more conducive to the collection and discharge of glue. A glue storage tank is installed in front of the glue application outlet pipe. By storing excess glue in the glue storage tank, a stable glue discharge can be ensured during the glue discharge process through the outlet pipe. This avoids the problem of uneven glue application caused by insufficient glue supply due to the instability or intermittent glue supply of the glue pump. A simple circulating glue supply is adopted to avoid and reduce losses and interruption of the feeding process. In order to control the glue discharge and the glue quantity at any time, a valve 14 is installed on the outlet pipe 8.

[0015] To simplify the portal frame structure, the portal frame 7 includes two angle steels 701 and two square frames 702. The two square frames 702 are fixedly connected to the top surfaces of both sides of the gluing machine frame 4. The two angle steels 701 are symmetrically fixedly connected to the top of the two square frames 702 and arranged opposite each other. The glue storage tank 3 is inserted into the limiting slot formed by the two angle steels 701 for limitation. This portal frame structure is simple, lightweight, easy to install, low in cost, has good support rigidity and stability. The limiting slot structure allows the glue storage tank to be adjusted in position. When applying glue to small-sized packaging cardboard and conveying it to one side, it can be moved to the corresponding position so that the glue flows into the middle of the packaging cardboard in the direction of conveying, thereby controlling the amount of glue released to meet the glue usage requirements.

[0016] To ensure the stability and uniformity of the glue application, the belt of the feeding conveyor 5 is 3-5mm higher than the lowest point of the gluing roller 1. A pressing strip frame 15 is installed on the upper side of the feeding conveyor 5. The pressing strip frame 15 presses the wine box packaging cardboard 16 forward and adheres it to the gluing roller 1, overlapping it onto the discharge suction conveyor 6. The inlet end of the discharge suction conveyor 6 is equipped with a ramp 16. The slope of the ramp 16 ensures that the wine box packaging cardboard can elastically adhere to the gluing roller even before entering the ramp. During the glue application process, the wine box packaging cardboard 16... Above the recycling glue tank 12, the packaging cardboard is fed into the gluing roller via a glue-feeding pressing strip. The cantilever extends and adheres to the surface of the gluing roller, making elastic contact for gluing and improving the uniformity of gluing. After gluing, the free end of the cantilever overlaps the discharge suction belt for suction and conveying, which can stably complete the gluing of the packaging cardboard. This structure can ensure the uniformity and stability of gluing. Moreover, the wine box packaging cardboard remains above the recycling glue tank 12 throughout the transition gluing and conveying process, avoiding interference with the recycling glue tank 12.

[0017] To increase the effective contact area and improve the uniformity of pressing the packaging cardboard, the pressing strip frame 15 includes multiple longitudinal pressing strips 1501 and a transverse plate 1502. The multiple longitudinal pressing strips 1501 are evenly spaced and fixedly connected to the transverse plate 1502 at their upper ends. The two ends of the transverse plate 1502 are fixedly connected to the two sides of the belt frame of the feeding belt conveyor 5 through support columns 1503. Through the strip structure, the contact with the packaging cardboard can be reduced, the stable and effective contact can be improved, and the packaging cardboard can be more evenly and flatly entered into the gluing roller for gluing.

[0018] Operating principle: Start the glue-applying roller to rotate, open the valve to release the glue. When the glue on the glue-applying roller is evenly coated, the pneumatic feeding belt 5 feeds the packaging cardboard. The packaging cardboard enters the glue-applying roller for gluing, and under the action of the pressing strip frame, it cantilever forward a short distance before contacting the discharge suction conveyor belt for suction and gluing. When the end of the packaging cardboard enters the glue-applying roller, under the action of the inclined surface suction as a fulcrum, the packaging cardboard is also in a cantilever elastic contact with the glue-applying roller, and finally the gluing of the packaging cardboard is completed, and it enters the next interval of packaging cardboard for gluing.
