[0002] A box gluing machine is a machine used to glu packaging boxes. It is the final step in packaging box processing and is used to fold and glue printed and die-cut cardboard.

[0003] Existing gluing machines typically apply glue to cardboard using rollers. After gluing the previous cardboard, the rollers briefly go into the air, and the glue on the rollers can easily drip onto the gluing machine or the floor, requiring periodic cleaning. The ease of use needs to be improved. Utility Model Content

[0004] This application aims to solve at least one of the technical problems in the background art by providing an anti-drip adhesive coating box and a box gluing machine.

[0005] This application is achieved through the following technical solution:

[0006] In a first aspect, this application provides an anti-drip adhesive coating box, comprising:

[0007] A box body having an opening;

[0008] A glue-applying roller, which is located in the opening and is elastically slidably connected to the box body;

[0009] The coating roller has a first state and a second state when it slides elastically. When the coating roller is in the first state, the coating roller and the opening form a sealed fit. When the coating roller is in the second state, a gap is formed between the coating roller and the opening for the flow of adhesive.

[0010] In some optional embodiments, the outer wall of the box is provided with a first sliding groove and a second sliding groove, a first slider is elastically slidably engaged in the first sliding groove, and a second slider is engaged in the second sliding groove, wherein the second sliding groove is formed from the bottom of the first sliding groove;

[0011] The second slider and the first slider are respectively connected to the glue-applying roller.

[0012] In some alternative embodiments, the coating roller and the second slider are rotatably connected via rolling bearings.

[0013] In some alternative embodiments, the second slider is configured with a plurality of balls that are in contact with the groove wall of the first slider by means of a groove locking ball process.

[0014] In some optional embodiments, the bottom of the first groove has a mating groove, and the wall of the mating groove has a mating hole;

[0015] The first slider is connected to a slide rod adapted to the mating hole, and a helical spring for abutting against the wall of the mating groove is sleeved on the slide rod.

[0016] In some alternative embodiments, the number of mating holes is two.

[0017] In some optional embodiments, the bottom of the first chute is provided with a first air inlet communicating with the inside of the box, and the first slider is provided with a second air inlet. When the glue-applying roller is in the first state, the first air inlet and the second air inlet are staggered. When the glue-applying roller is in the second state, the first air inlet and the second air inlet are connected.

[0018] In some alternative embodiments, an end cap is attached to the first slider.

[0019] Secondly, this application provides an anti-drip glue gluing machine, comprising:

[0020] Support frame;

[0021] A conveyor belt connected to the support frame for transporting cardboard;

[0022] A pressure plate mechanism is connected to the support frame, and there is a gap between the pressure plate mechanism and the conveyor belt that is smaller than the thickness of the cardboard.

[0023] The adhesive applicator of any of the anti-drip adhesives described in the first aspect is connected to the support frame, and the adhesive applicator roller of the adhesive applicator has a gap smaller than the thickness of the cardboard between it and the support frame to apply adhesive to the edge of the cardboard.

[0024] In some alternative embodiments, the glue applicator is slidably connected to the support frame via a connecting bracket, wherein a set screw is connected to the connecting bracket.

[0025] Compared with the prior art, this application has the following advantages and beneficial effects:

[0026] This application provides an anti-drip glue coating box and a box gluing machine. The glue coating roller is elastically slidably connected to the box body. When the cardboard passes between the glue coating roller and the support frame, the cardboard can elastically lift the glue coating roller, thereby changing the movement state of the glue coating roller. That is, when the cardboard is between the glue coating roller and the support frame, the glue coating roller is in the second state, so that the glue inside the box is carried out by the rotating glue coating roller to coat the cardboard. When the glue coating roller is in the air, the glue coating roller elastically returns to the first state. At this time, the glue coating roller seals the opening of the box body, and the glue inside the box body will not flow out of the box body, thereby preventing glue dripping and eliminating the need for periodic cleaning of dripping glue, thus improving the convenience of use.

[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0037] Firstly, such as Figures 1-4As shown in the figure, this application embodiment provides an anti-drip adhesive coating box, which includes a box body 1 and an adhesive coating roller 2. The box body 1 consists of two parts: the first part is a rectangular groove, and the second part is a trapezoidal shape with openings at the top and bottom. The larger opening of the second part connects with the first part to form an adhesive storage cavity, and the smaller opening of the second part serves as the adhesive dispensing opening of the box body 1. The adhesive coating roller 2 is located in the opening and is elastically slidably connected to the box body 1. When the adhesive coating roller 2 elastically slides, it can move into the adhesive storage cavity. In its natural state, the adhesive coating roller 2 abuts against the edge of the opening of the box body 1. The adhesive coating roller 2 has a first state and a second state when it elastically slides. When the adhesive coating roller 2 is in the first state, it forms a sealed fit with the opening. When the adhesive coating roller 2 is in the second state, a gap is formed between the adhesive coating roller 2 and the opening for the flow of adhesive.

[0038] As a specific embodiment of the elastic sliding connection between the coating roller 2 and the box body 1, the outer wall of the box body 1 is provided with a first sliding groove 11 and a second sliding groove 12. The first sliding groove 11 is a rectangular groove, and the second sliding groove 12 is also a rectangular groove. The second sliding groove 12 connects the first sliding groove 11 and the glue storage cavity. A first slider 13 is elastically slidably fitted in the first sliding groove 11, that is, the first slider 13 can elastically slide in the length direction of the first sliding groove 11. A second slider 14 is fitted in the second sliding groove 12. The second sliding groove 12 is formed from the bottom of the first sliding groove 11. The second slider 14 and the first slider 13 are respectively connected to the coating roller 2.

[0039] In this embodiment, the dual slider design of the first slider 13 and the second slider 14 ensures that the coating roller 2 does not wobble during the sliding process, and ensures the sealing stability between the coating roller 2 and the opening of the box 1 after elastic reset.

[0040] In some alternative embodiments, the glue-applying roller 2 and the second slider 14 are rotatably connected by rolling bearings.

[0041] In this embodiment, the cylinder on the coating roller 2 can rotate around its own central axis. After the coating roller 2 is engaged with the second slider 14 through the rolling bearing, the rotation sensitivity of the coating roller 2 can be further improved, thereby enabling the coating roller 2 to apply glue evenly and stably.

[0042] In some optional embodiments, the second slider 14 is equipped with a plurality of balls that are in contact with the groove wall of the first slide groove 11 by means of a groove locking ball process; this setting can improve the sliding sensitivity of the second slider 14, avoid jamming, and ensure that the glue roller 2 forms a stable sealing fit with the opening of the box body 1 after elastic reset.

[0043] As a specific embodiment of the elastic sliding between the first slider 13 and the first groove 11, the bottom of the first groove 11 has a mating groove 15, which is a rectangular groove. The length direction of the mating groove 15 is parallel to the length direction of the first groove 11. A mating hole is provided on the groove wall of the mating groove 15, which is specifically provided on the groove wall at one end of the length direction of the mating groove 15. A sliding rod 16 adapted to the mating hole is connected to the first slider 13. A helical spring 17 for abutting against the groove wall of the mating groove 15 is sleeved on the sliding rod 16.

[0044] In this embodiment, the design of the slide bar 16 and the mating hole can provide auxiliary guidance, thereby preventing the first slider 13 from getting stuck in the first slide groove 11.

[0045] In some optional embodiments, the number of mating holes is two, and the two mating holes are arranged at intervals along the width direction of the mating groove 15.

[0046] In some optional embodiments, the bottom of the first slide groove 11 is provided with a first air inlet 18 that communicates with the inside of the box body 1, and the first slider 13 is provided with a second air inlet 19. When the glue coating roller 2 is in the first state, the first air inlet 18 and the second air inlet 19 are staggered. When the glue coating roller 2 is in the second state, the first air inlet 18 and the second air inlet 19 are connected.

[0047] In this embodiment, after the glue-applying roller 2 and the opening of the box body 1 form a sealed fit, the first slider 13 can block the first air inlet 18, thereby keeping the glue storage cavity in a sealed state. This can prevent accidental glue leakage due to a decrease in the fit accuracy between the glue-applying roller 2 and the box body 1.

[0048] In some optional embodiments, an end cap 3 is connected to the first slider 13, and the end of the central rotating shaft of the glue coating roller 2 is located in the end cap 3; the end cap 3 can protect the central rotating shaft of the glue coating roller 2, and at the same time can seal the gap between the central rotating shaft and the first slider 13 to prevent air from entering the glue storage cavity.

[0049] Secondly, such as Figure 5As shown, this application embodiment provides an anti-drip glue gluing machine, which includes a support frame 10, a conveyor belt 40, and a pressure plate mechanism 30. The support frame 10 is generally a rectangular groove, which provides support for the entire device. The conveyor belt 40 is connected to the support frame 10 to transport cardboard; specifically, the conveyor belt 40 is located in the groove of the support frame 10. The pressure plate mechanism 30 is connected to the support frame 10, and there is a gap between the pressure plate mechanism 30 and the conveyor belt 40 smaller than the thickness of the cardboard. In actual implementation, the pressure plate mechanism 30 consists of a connecting seat, rollers, and a connecting rod. The rod includes a horizontal bar and two vertical bars. The two vertical bars are respectively connected to both sides of the support frame 10 in the width direction. The two ends of the horizontal bar are respectively connected to the two vertical bars. The connecting seat is connected to the horizontal bar. The connecting seat is a rectangular block. The length direction of the connecting seat is parallel to the length direction of the conveyor belt 40. There are multiple rollers. The multiple rollers are rotatably connected to the connecting seat and are arranged at intervals along the length direction of the connecting seat. As described in the first aspect, the glue coating box 20 is connected to the support frame 10. The glue coating roller 2 of the glue coating box 20 has a gap smaller than the thickness of the cardboard between it and the support frame 10 to apply glue to the edge of the cardboard.

[0050] Working principle: The conveyor belt 40 transports the cardboard to the pressing mechanism 30 for placement. The pressing mechanism 30 applies pressure to the cardboard to achieve its positioning. The outer side of the cardboard corresponds vertically to the glue-coating box 20. Since the gap between the glue-coating roller 2 and the support frame 10 is smaller than the thickness of the cardboard, the cardboard will lift the glue-coating roller 2, putting it in the second state. As the cardboard moves forward, the glue-coating roller 2 will rotate under the drive of the cardboard to carry out the glue in the glue storage chamber and coat it onto the cardboard. When the cardboard leaves the space between the glue-coating roller 2 and the support frame 10, the glue-coating roller 2 elastically resets to the first state. The glue-coating roller 2 forms a sealing fit with the opening of the box 1 to prevent the glue in the glue storage chamber from dripping.

[0051] In some optional embodiments, the glue coating box 20 is slidably connected to the support frame 10 via a connecting frame, wherein a set screw is connected to the connecting frame; this configuration allows for adjustment of the gap between the glue coating roller 2 and the support frame 10 by adjusting the height of the glue coating box 20, thereby making it suitable for cardboard of different thicknesses and improving the applicability of the gluing machine.
