Description

Technical Field

[0001] This utility model relates to the technical field of packaging carton production, and in particular to a high-efficiency and environmentally friendly heavy-duty gluing machine. Background Technology

[0002] Currently, in the production of packaging cartons, especially large packaging cartons such as television sets (also known as heavy-duty packaging), glue is often applied to bond and fix different cardboard pieces together. The glue application area is large, and heavy-duty packaging glue coaters can often be used for full-page glue application. However, when local glue application and bonding are required, ordinary heavy-duty packaging glue coaters cannot achieve local glue application. Therefore, in actual production, most local glue application needs to be done manually, which is time-consuming, labor-intensive, has low production efficiency, and results in inconsistent glue application area sizes and poor bonding effects. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency and environmentally friendly heavy-duty adhesive applicator, which has the function of local adhesive application, can save manpower, improve production efficiency, and save glue, making it more environmentally friendly.

[0004] To achieve the above objectives, the solution of this utility model is:

[0006] The frame includes a left frame and a right frame. An upper glue-coating roller, a lower glue-coating roller, and a glue trough are arranged sequentially and vertically between the left frame and the right frame. Both the upper glue-coating roller and the lower glue-coating roller are rotatably connected to the left frame and the right frame. The bottom of the upper glue-coating roller is located inside the glue trough.

[0007] Two baffles are spaced apart in the glue tank, dividing the glue tank into a middle glue tank and two overflow glue tanks on the left and right. The two baffles are adjustable by sliding left and right.

[0008] Two scraper blades are installed on the lower rear side of the glue-coating roller, which can be moved left and right respectively, and are located on both sides of the glue tank. At the same time, the scraper blades extend and contact the lower glue-coating roller.

[0009] Furthermore, the height of the glue baffle does not exceed the glue groove, and it is fitted with a gap to the bottom of the lower glue roller.

[0010] Furthermore, two lead screw mechanisms are provided on the front side of the frame, which are used to drive the two rubber baffles to slide left and right respectively.

[0011] Furthermore, the lead screw mechanism includes two connecting plates, guide posts, a sliding plate, a lead screw, a lead screw slider, and a hand crank. The two connecting plates are spaced apart horizontally, the guide posts and the lead screw are distributed vertically and connected to the two connecting plates at both ends respectively, and the two ends of the lead screw are rotatably connected to the two connecting plates. At the same time, one end of the lead screw passes through one of the connecting plates and is connected to the hand crank. The rotation of the hand crank drives the lead screw to rotate. The lead screw slider slides on the lead screw. The sliding plate is located between the two connecting plates and has a sliding hole for the guide post to pass through. The middle of the sliding plate also has a mounting hole for connection and fixation with the lead screw slider. The upper end of the sliding plate is connected and fixed to the baffle plate in the glue groove through an extension arm.

[0012] Furthermore, the two lead screw mechanisms are symmetrically arranged on the left and right sides, and the two hand cranks are located on the left and right sides respectively.

[0013] Furthermore, the lead screw mechanism includes two connecting plates, guide posts, a sliding plate, a lead screw, a lead screw slider, and a motor; the two connecting plates are spaced apart horizontally, the guide posts and the lead screw are distributed vertically and connected to the two connecting plates at both ends respectively, and the two ends of the lead screw are rotatably connected to the two connecting plates respectively. At the same time, one end of the lead screw passes through one of the connecting plates and is connected to the motor, and the motor drives the lead screw to rotate; the lead screw slider slides on the lead screw, the sliding plate is located between the two connecting plates and has a sliding hole for the guide post to pass through, the middle of the sliding plate also has a mounting hole to connect and fix it to the lead screw slider, and the upper end of the sliding plate is connected and fixed to the baffle plate in the glue groove through an extension arm.

[0014] Furthermore, a fixing rod is provided on the rear side of the lower coating roller feed; the fixing rod is provided with several locking holes spaced apart from left to right; the scraper plate is provided with at least two connecting holes, and adjusting screws are inserted into the connecting holes, and the adjusting screws are simultaneously locked into the locking holes of the fixing rod.

[0015] Furthermore, the two ends of the fixing rod are connected to the left frame and the right frame, or fixed to the rear edge of the glue tank.

[0016] Furthermore, a return pipe is installed on the front side of the overflow tank, the return pipe is connected to the overflow tank, and a switch valve is provided on the return pipe.

[0017] After adopting the above technical solution, in specific production, firstly, the positions of the two glue-blocking plates are adjusted according to the width of the area in the middle of the cardboard that needs to be glued, so that the glue tank in the glue trough and the area of ​​the cardboard that needs to be glued are aligned and maintain a consistent width. Then, the glue tank is filled with glue, and the lower glue-coating roller rotates to pick up glue from the glue tank, forming a glued area in the middle and glue-free areas on both sides on the lower glue-coating roller. The glue on the glued area in the middle can be transferred to the bottom surface of the cardboard conveyed between the upper and lower glue-coating rollers as the lower glue-coating roller rotates, thereby achieving localized glue coating of the cardboard. This can significantly save manpower and improve the efficiency of localized glue coating.

[0018] Meanwhile, due to the centrifugal force during the rotation of the lower coating roller, the glue picked up in the coating area is prone to overflowing into the non-glue area. Therefore, by setting two scraper blades, the glue overflowing into the non-glue area can be blocked and scraped off, ensuring that the glue line between the coating area and the non-glue area on the lower coating roller is clear, ensuring that the coating range in the middle coating area is accurate and uniform, and also allowing the overflowing glue to flow back into the overflow tank for subsequent collection, thus saving glue and being more environmentally friendly.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] like Figures 1 to 4 As shown, the high-efficiency and environmentally friendly repackaging glue applicator of this embodiment can be improved from ordinary glue applicators, with low modification costs, and can realize automated local glue applicator, which can meet the production needs of products that require local glue applicator.

[0026] The glue applicator includes a frame 1, an upper glue applicator roller 2, a lower glue applicator roller 3, a glue tank 4, two glue baffles 5, and two glue scrapers 6.

[0027] The frame 1 includes a left frame 11 and a right frame 12. An upper glue-coating roller 2, a lower glue-coating roller 3, and a glue tank 4 are arranged sequentially and vertically between the left frame 11 and the right frame 12. Both the upper glue-coating roller 2 and the lower glue-coating roller 3 are rotatably connected to the left frame 11 and the right frame 12. The cardboard passes between the upper glue-coating roller 2 and the lower glue-coating roller 3. The upper glue-coating roller 2 can be moved up and down and connected to the left frame 11 and the right frame 12 (this is prior art, and the figure is a schematic diagram without showing the specific structure) to facilitate adjustment of the pressure of the upper glue-coating roller 2. The glue tank 4 is used to hold glue. The bottom of the upper glue-coating roller 2 is located in the glue tank 4 and immersed in the glue to roll and pick up glue so that the glue is applied to the bottom surface of the cardboard when it passes through.

[0028] Two baffle plates 5 are spaced apart in the glue tank 4, dividing the glue tank 4 into a central glue tank 41 and two overflow glue tanks 42 on the left and right. The two baffle plates 5 are adjustable left and right, so the left and right width of the glue tank 41 can be adjusted by changing the position of the baffle plates 5. Two scraper plates 6 are respectively installed on the lower rear side of the lower glue roller 3, which is movable left and right, and are located on both sides of the glue tank 41. The scraper plates 6 extend and contact the lower glue roller 3 (see...). Figure 4 ).

[0029] The glue applicator in this embodiment can be mainly used for local glue application in the middle of cardboard. In specific production, firstly, according to the width of the area to be glued in the middle of the cardboard, the positions of the two glue baffles 5 are adjusted so that the glue tank 41 in the glue tank 4 is aligned with the area to be glued on the cardboard and the width is consistent. Then, the glue tank 41 in the glue tank 4 is filled with glue, and the lower glue applicator 3 rotates to pick up glue from the glue tank 41, forming a glued area 31 in the middle and glue-free areas 32 on both sides on the lower glue applicator 3 (see...). Figure 3 The glue on the central coating area 31 can be transferred to the bottom surface of the cardboard conveyed between the upper coating roller 2 and the lower coating roller 3 as the lower coating roller 3 rotates, thereby achieving localized glue coating of the cardboard. Compared with manual glue coating, the rotating glue coating roller 3 in this embodiment not only coats the cardboard evenly but also at a fast speed, which can effectively improve production efficiency.

[0030] Meanwhile, due to the centrifugal force during the rotation of the lower coating roller 3, the glue dipped in the coating area 31 is prone to overflowing into the non-glue area 32. Therefore, by setting two scraper plates 6, the glue overflowing onto the non-glue area 32 can be blocked and scraped off, so as to ensure that the glue line between the coating area 31 and the non-glue area 32 on the lower coating roller 3 is clear, and to ensure that the coating range of the middle coating area 31 is accurate and uniform. It can also allow the overflowing glue to flow back into the overflow tank 42 for subsequent collection.

[0031] In this embodiment, the height of the baffle plate 5 does not exceed the glue trough 4, and it can be fitted with the bottom gap of the lower glue roller 3 to avoid interfering with the rotation of the lower glue roller 3; although the glue trough 41 between the two baffle plates 5 will first be filled with glue and then flow over the baffle plate 5 to the overflow trough 42, the glue in the overflow trough 42 is not full, so the glue-free area 32 of the lower glue tube will not be contaminated with glue.

[0032] In this embodiment, the width of the scraper 6 only needs to be greater than the width of the overflowing glue, and it does not need to be too long.

[0033] In this embodiment, two external lead screw mechanisms 7 can be provided on the front side of the frame 1, so as to realize the rapid adjustment of the position of the baffle plate 5.

[0034] Specifically, the lead screw mechanism 7 includes two connecting plates 71, two guide posts 72, a sliding plate 73, a lead screw 74, a lead screw slider 75, and a hand crank 76.

[0035] Two connecting plates 71 are spaced apart on the left and right, and two guide posts 72 are distributed vertically and connected to the two connecting plates 71 at both ends. A lead screw 74 is located between the two guide posts 72 and its two ends are rotatably connected to the two connecting plates 71. At the same time, one end of the lead screw 74 passes through one of the connecting plates 71 and is connected to a hand crank 76. The rotation of the hand crank 76 drives the lead screw 74 to rotate. The lead screw slider 75 slides on the lead screw 74. The slide plate 73 is located between the two connecting plates 71 and has two sliding holes 731 for the two guide posts 72 to pass through. The slide plate 73 also has a mounting hole 732 in the middle to connect and fix it to the lead screw slider 75. The upper end of the slide plate 73 can be connected and fixed to the baffle plate 5 in the glue groove 4 through the extension arm 77.

[0036] Therefore, when it is necessary to adjust the baffle plate 5 to move left or right, simply crank the hand crank 76 to drive the lead screw 74 to rotate. The rotation of the lead screw 74 drives the lead screw slider 75 to slide. The sliding of the lead screw slider 75 can drive the baffle plate 5 to move through the slide plate 73 and the extension arm 77. It is convenient to use and the structure is stable and reliable.

[0037] In this embodiment, two guide posts 72 are provided at the top and bottom to make the sliding plate 73 slide more stably. Of course, in practice, only one guide post 72 can be provided.

[0038] Furthermore, the hand crank 76 can also be replaced with a motor or other structure, which can electrically drive the lead screw 74 to rotate, further saving manpower.

[0039] In this embodiment, the two lead screw mechanisms 7 are arranged symmetrically on the left and right, and the two hand cranks 76 are located on the left and right sides respectively, which can facilitate the independent adjustment of the baffle plate 5.

[0040] In this embodiment, a fixing rod 8 can be provided on the rear side of the feeding of the lower coating roller 3. The two ends of the fixing rod 8 can be connected to the left frame 11 and the right frame 12. The fixing rod 8 can also be directly fixed to the rear edge of the glue tank 4. The fixing rod 8 is provided with a number of locking holes 81 spaced left and right. The scraper 6 can be provided with at least two connecting holes 61. An adjusting screw (not shown in the figure) passes through the connecting hole 61. The adjusting screw is locked in the locking hole 81 of the fixing rod 8. Thus, by adjusting the position of the locking hole 81 locked by the adjusting screw, the position of the scraper 6 can be adjusted left and right. It can be adjusted adaptively with the adjustment of the glue baffle 5. Moreover, the width of the scraper 6 can also be replaced as needed.

[0041] In this embodiment, a return pipe 9 can also be installed on the front side of the overflow trough 42. The return pipe 9 is connected to the overflow trough 42, and a switch valve 91 can be provided on the return pipe 9. At the same time, a screw mechanism 7 can extend from the front end of the return pipe 9. When in use, a glue bucket (not shown) can be placed below the front end of the return pipe 9, and then the switch valve 91 can be opened to recover the glue in the overflow trough 42. This can prevent the glue in the overflow trough 42 from accumulating and causing the glue-free area 32 of the lower coating roller 3 to be contaminated with glue.
