Description

Technical Field

[0001] This utility model specifically relates to a dual-channel gluing mechanism. Background Technology

[0002] A carton gluing machine is an automated device used to apply glue to various cardboard boxes. Gluing methods include top-side gluing and back-side gluing. The carton gluing machine uses glue-soaked rollers connected to the box to apply glue over the surface of the cardboard.

[0003] Currently, most gluing machines use spring-loaded gluing. As the paper travels along the paper feeder, the edges of the paper extend beyond the frame, and gluing is achieved through the stiffness of the paper and its contact with the gluing rollers. However, due to inconsistent paper stiffness standards, especially with the advent of high-bulk paper, the paper's hardness and stiffness are often insufficient. This results in inadequate contact pressure between the gluing rollers and the paper, frequently leading to insufficient gluing, glue breakage, and glue overflow, severely impacting production speed and the quality of the glued boxes. Furthermore, applying gluing only once cannot ensure even glue distribution on the cardboard, and this single application can cause uneven glue application, easily resulting in wasted glue dripping. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dual-channel gluing mechanism.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0020] 3. The design of the cardboard rolling frame and roller assembly ensures stable cardboard conveying and prevents deviation. In particular, the rubber wheels increase friction, effectively helping the cardboard to smoothly enter the gluing conveyor frame and improving the stability of the system.

[0021] 4. The design of the anti-warping pressure plate for cardboard can effectively prevent cardboard from warping during the conveying process, keep the cardboard flat, ensure the quality of subsequent processing, and reduce possible errors or damage during production.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0029] Example

[0030] A dual-channel gluing mechanism, such as Figure 1-6As shown, it includes a dual-channel feeding conveyor frame 1, baffle plates 2 installed on both sides of the dual-channel feeding conveyor frame 1, a dual-channel gluing conveyor frame 3 connected to the dual-channel feeding conveyor frame 1, a cardboard rolling frame 4 installed above the dual-channel gluing conveyor frame 3, a first gluing box 5 installed on the side of the dual-channel gluing conveyor frame 3, a second gluing box 6 installed on the dual-channel gluing conveyor frame 3 and on the same side as the first gluing box 5, a drive shaft 7 connected to the drive end of the dual-channel gluing conveyor frame 3, and a drive chain 8 mounted on the drive shaft 7 that connects the first gluing box 5 and the second gluing box 6 respectively.

[0031] It should be further explained that the specific function of the baffle plate 2 is to prevent the cardboard from sliding out of the dual-channel feeding conveyor 1 when the cardboard is placed on it. In addition, the baffle plate 2 can also correct the position of the cardboard during the conveying process so that it can smoothly enter the dual-channel gluing conveyor frame 3 to cooperate with the cardboard rolling frame 4, the first gluing box 5 and the second gluing box 6 for gluing treatment.

[0032] The cardboard rolling frame 4 includes a lifting frame 41 that spans across the dual-channel gluing conveyor frame 3 and is fixedly installed at both ends to the sides of the dual-channel gluing conveyor frame 3, and cardboard rolling assemblies 42 installed at both ends below the lifting frame 41.

[0033] The cardboard rolling assembly 42 includes a horizontal channel steel 421 fixed to the lifting frame 41 by bolts, a rectangular support arm 422 placed inside the horizontal channel steel 421 and fixedly installed by bolts, an assembly strip 423 fixedly installed at one end of the rectangular support arm 422, a roller group 424 evenly distributed below the assembly strip 423, and a cardboard anti-warping pressure plate 425 fixedly installed at the other end of the rectangular support arm 422.

[0034] Two mounting ears 4211 with a spacing consistent with the width of the lifting frame 41 are welded to the upper end of the horizontal channel steel 421. Specifically, the mounting ears 4211 contact the side of the lifting frame 41 and are fixedly installed by screwing in bolts.

[0035] The upper end of the assembly strip 423 is welded with an assembly strip connecting bolt 4231, which passes through the rectangular support arm 422 and is fixed by a nut.

[0036] The roller assembly 424 includes an inverted U-shaped lifting component 421 that is fixedly installed to the assembly strip 423 by bolts, a tire assembly beam 4242 that is fixedly installed to the lifting component 4241, and a rubber wheel 4243 installed on the tire assembly beam 4242. Specifically, the roller assembly 424 is provided with three sets. In the actual production process, the roller assembly 424 serves as the board feeding end. The rubber wheel 4243 can increase the friction to feed the cardboard and also prevent the cardboard from deviating.

[0037] The upper end of the cardboard anti-warping pressure plate 425 is welded with an anti-warping pressure plate connecting bolt 4251, which passes through the rectangular support arm 422 and is fixed by a nut.

[0038] The first glue application box 5 includes a glue storage box body 51, a glue application assembly 52 installed inside the glue storage box body 51, and a guide plate assembly 53 fixedly installed above the glue storage box body 51 to cooperate with the glue application assembly 52 for glue application.

[0039] A top plate 511 is fixedly installed on the top of the glue storage box 51, a glue inlet 512 is opened on one side of the top plate 511, a cover plate 513 that cooperates with the glue inlet 512, a strip glue groove 514 is opened on the other side of the top plate 511, and a cardboard support strip 515 is welded to the top plate 511 and parallel to the strip glue groove 514.

[0040] The glue assembly 52 includes a first bearing seat 521 fixedly installed on the inner side wall of the glue storage tank 51, a second bearing seat 522 fixedly installed on the outer side wall of the glue storage tank 51 and coaxial with the first bearing seat 521, a glue application shaft 523 that passes through the second bearing seat 522 into the glue storage tank 51 and is assembled with the first bearing seat 521, a glue application wheel 524 fixedly installed on the glue application shaft 523 and located inside the glue storage tank 51, and a meshing gear 525 fixedly installed on the glue application shaft 523 and located outside the glue storage tank 51.

[0041] In the structure of the first gluing box 5, the upper part of the gluing wheel 524 extends beyond the strip gluing groove 514, and the meshing gear 525 is connected by the transmission chain 8 and the transmission shaft 7. Therefore, during operation, the upper part of the gluing wheel 524 contacts the conveyed cardboard and applies glue to the cardboard. After the cardboard is output, it is convenient for manual folding to form a box and can be glued and fixed.

[0042] The guide plate assembly 53 includes a support stud 531 located above the glue storage tank 51 and screwed to the glue storage tank 51, a support block 532 fitted on the upper end of the support stud 531 and fixed by two nuts, a lifting bolt 533 located at one end of the support block 532 and passing through the support block 532 and then limited by a nut, a spring 534 fitted on the lifting bolt 533, an auxiliary block 535 fixedly installed at the lower end of the lifting bolt 533 and abutting against the spring 534, a cardboard pressure strip 536 welded below the auxiliary block 535, a lifting plate 537 fixedly installed on the other side of the support block 532 by screws, and a cardboard pressure roller 538 mounted on the lifting plate 537.

[0043] The cardboard lower pressure strip 536 cooperates with the cardboard support strip 515 to prevent the cardboard from jumping and folding during the conveying process. Under the tension of the spring 534, the cardboard lower pressure strip 536 can be pressed tightly against the cardboard. The cardboard pressure roller 538 cooperates with the glue roller 524 to squeeze the cardboard, so that the cardboard and the glue roller 524 can fully contact each other for glue application.

[0044] It should be further explained that the structure of the second gluing box 6 is the same as that of the first gluing box 5. With the transmission shaft 7 and the transmission chain 8 working together, the structure of the second gluing box 6 and the first gluing box 5 can be driven simultaneously to apply glue to the cardboard being transported twice, which can ensure that the glue is evenly coated on the cardboard and avoid uneven glue application or waste.
