Description

Technical Field

[0001] This utility model relates to the field of paper box gluing technology, and in particular to an automatic gluing mechanism for a box gluing machine. Background Technology

[0002] In the paper packaging industry, cardboard boxes are used in huge quantities. Various products such as food, medicine, and electronic products all require a large number of cardboard boxes for packaging. With the increasing market demand for product packaging, traditional manual gluing or simple mechanical gluing methods are no longer sufficient to meet the requirements of large-scale production in terms of efficiency and quality. Automatic gluing machines have emerged and are constantly developing towards high speed, high efficiency, and high precision. As one of its core components, the gluing mechanism also needs to be continuously innovated and improved to adapt to the development of the industry.

[0003] The existing equipment is prone to uneven coating during the gluing process, which prevents the glue from being applied evenly to the paper. This results in a large number of defective products during production. During the operation of the gluing machine, the paper may tilt during the conveying process. When this happens, the cardboard will have errors when it reaches the next processing area, which greatly reduces the product qualification rate and causes serious economic losses.

[0004] Existing patent (publication number: CN212708249U) discloses an automatic gluing mechanism for a carton gluing machine, comprising a main support, a conveying device, a fixing device, a feeding device, and a smoothing device. The main support is vertically arranged, the conveying device is located on top of the main support, and several fixing devices are provided at equal intervals on top of the conveying device. The feeding device is located on one side of the main support and on the opposite side of the fixing devices, with its discharge end located above the conveying device. The smoothing device is located on one side of the main support and beside the feeding device. This invention uses the fixing device to fix the paper to the conveying device, preventing the paper from swaying left and right on the conveying device and ensuring that the paper is stably conveyed forward on the conveying device. The feeding device sprays glue onto the paper, and the smoothing device evenly spreads the glue sprayed by the feeding device onto the paper.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the existing automatic gluing machine's gluing mechanism lacks a structure for scraping and collecting the glue after applying it to the cardboard box. This results in uneven glue distribution on the cardboard box surface, with excessive glue accumulation in some areas and insufficient glue in others. This excess glue not only causes waste but may also overflow during subsequent cardboard box folding and assembly, contaminating the cardboard box surface and affecting the product's appearance quality.

[0006] Therefore, an automatic gluing mechanism for a box gluing machine is proposed. Utility Model Content

Detailed Implementation

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An automatic box gluing machine gluing mechanism includes a support platform 1, with limiting grooves 2 on both sides of the support platform 1, a clamping mechanism 3 rotatably connected to the inner side of the limiting grooves 2, a working plate 4 fixedly connected to the bottom of the inner side of the support platform 1, and a gluing mechanism 5 fixedly connected to the top of the support platform 1.

[0029] The glue application mechanism 5 includes a limiting plate 501, a glue storage tank 502, a pressure pump 503, a connecting plate 504, several nozzles 505, a glue scraper 506, a support rod 507, a glue scraper roller 508, a glue leakage hole 509, and a glue guide box 510. The limiting plate 501 is fixedly connected to the top of the support platform 1. The glue storage tank 502 is fixedly connected to the left side of the top of the limiting plate 501. The pressure pump 503 is fixedly connected to the top of the limiting plate 501. The left side of the pressure pump 503 is fixedly connected to the bottom right side of the glue storage tank 502. The right side of the pressure pump 503 passes through the limiting plate 501 and is fixedly connected to the connecting plate 510. The top of plate 504, the connecting plate 504 is fixedly connected to the bottom of the limiting plate 501, the nozzle 505 is fixedly connected to the bottom of the connecting plate 504, the glue scraper 506 is fixedly connected to the rear side of the limiting plate 501, the support rod 507 is fixedly connected to both sides of the limiting plate 501, the glue scraper roller 508 is rotatably connected to the side of the support rod 507 away from the limiting plate 501, the glue leakage holes 509 are respectively opened on the rear side of the working plate 4 and the rear side of the support platform 1, the glue guide box 510 is fixedly connected to the bottom of the support platform 1, and the top of the glue guide box 510 is fixedly connected to the bottom of the glue leakage hole 509.

[0030] In this embodiment: the support platform 1 supports and limits the limiting groove 2, the working plate 4, and the glue application mechanism 5. The limiting groove 2 provides a track and restriction for the clamping mechanism 3, allowing it to move along a specific path and ensuring the accuracy of clamping and positioning the cardboard box. The working plate 4 provides a flat support surface for the cardboard box, ensuring its stability during glue application and uniform glue application. The limiting plate 501 supports the glue storage tank 502, the pressure pump 503, the connecting plate 504, and the glue scraper 5. Support rod 506 and support rod 507 provide support and limit the flow of adhesive. Adhesive storage tank 502 stores adhesive, ensuring a continuous supply and preventing insufficient adhesive from affecting the continuity of the coating process, thus improving production efficiency. Pressure pump 503 pressurizes the adhesive in storage tank 502 and delivers it to connecting plate 504 and nozzle 505. Pressure pump 503 provides stable pressure, ensuring that the adhesive can be sprayed evenly and smoothly from nozzle 505. Connecting plate 504 connects pressure pump 503 and nozzle 505, allowing the adhesive to flow smoothly from the pressure pump... 503 is conveyed to nozzle 505, which sprays the pressurized glue evenly onto the surface of the cardboard box. Multiple nozzles 505 increase the coating area and uniformity, improving coating efficiency and quality. After gluing, the scraper 506 scrapes away excess glue from the cardboard box surface, ensuring more even glue distribution and preventing glue accumulation, thus improving the bonding and appearance quality of the cardboard box. Support rod 507 provides support and fixation for the scraper roller 508, ensuring stable rotation of the scraper roller 508. 08 After the glue scraper 506 initially smooths the glue, the glue roller 508 further rolls and smooths the glue, making the glue adhere more evenly to the surface of the cardboard box. At the same time, it can also increase the adhesion between the glue and the surface of the cardboard box and improve the bonding effect. The glue leakage holes 509 are respectively opened on the rear side of the work plate 4 and the rear side of the support table 1 to collect the excess glue during the glue scraping process. The glue guide box 510 is connected to the glue leakage hole 509 and collects the excess glue flowing down from the glue leakage hole 509, which facilitates the recycling and reuse of glue and reduces production costs.

[0031] Specifically, such as Figure 2 , Figure 3 As shown, the clamping mechanism 3 includes a lead screw 301, a limiting rod 302, a servo motor 303, a slider 304, a connecting rod 305, a connecting block 306, a cylinder 307, and a clamping plate 308. The lead screw 301 is rotatably connected to the inside of the left limiting groove 2.

[0032] Specifically, such as Figure 2 , Figure 3As shown, the limiting rod 302 is fixedly connected to the inner side of the right limiting groove 2, the servo motor 303 is fixedly connected to the front side of the support platform 1, the output end of the servo motor 303 passes through the support platform 1 and is fixedly connected to the front side of the lead screw 301, the left slider 304 is threadedly connected to the surface of the lead screw 301, and the right slider 304 is slidably connected to the surface of the limiting rod 302.

[0033] Specifically, such as Figure 2 , Figure 3 As shown, the left side of the connecting rod 305 is fixedly connected to the right side of the left slider 304, the right side of the connecting rod 305 is fixedly connected to the left side of the right slider 304, the connecting block 306 is fixedly connected to the surfaces on both sides of the connecting rod 305, the cylinder 307 is fixedly connected to the inner side of the connecting block 306, and the clamping plate 308 is fixedly connected to one side of the telescopic end of the cylinder 307.

[0034] In this embodiment: by setting the lead screw 301 to cooperate with the servo motor 303, the rotational motion of the servo motor 303 is converted into the linear motion of the slider 304. The limiting rod 302 can guide and limit the right slider 304, ensuring the smooth movement of the connecting rod 305, making the movement of the entire clamping mechanism 3 more stable and accurate. The servo motor 303 provides power for the rotation of the lead screw 301. The slider 304 moves the left slider 304 through the rotation of the lead screw 301, and then drives the right slider 304 to slide on the limiting rod 302 through the connecting rod 305. The entire clamping mechanism 3 moves, and the connecting rod 305 connects the left and right sliders 304, enabling the left and right sliders 304 to move synchronously, ensuring the integrity and stability of the clamping mechanism 3. The connecting block 306 provides an installation position for the cylinder 307, allowing the cylinder 307 to be stably installed on the clamping mechanism 3. The extension and retraction of the cylinder 307 can drive the opening and closing of the clamping plate 308. By controlling the extension and retraction of the cylinder 307, flexible clamping of paper boxes of different sizes can be achieved, adapting to the gluing requirements of various specifications of paper boxes. The clamping plate 308 directly contacts the paper box to achieve clamping of the paper box.

[0035] Specifically, such as Figure 3 As shown, the clamping surface of the clamping plate 308 is fitted with a protective sleeve 6, and the surface of the protective sleeve 6 is engraved with anti-slip texture.

[0036] Specifically, such as Figure 4 As shown, the bottom of the inner side of the adhesive guide box 510 is set as a slope, and the inner side of the adhesive guide box 510 is coated with an anti-stick coating.

[0037] In this embodiment: by setting the protective sleeve 6, direct contact between the clamping plate 308 and the surface of the cardboard box can be effectively avoided, preventing scratches, indentations and other damage to the surface of the cardboard box during clamping, thus protecting the appearance quality of the cardboard box. By setting the anti-slip texture, the friction between the clamping plate 308 and the cardboard box is increased, making the clamping of the cardboard box more secure. By setting the bottom of the inner side of the glue guide box 510 as a slope, it is beneficial to collect the glue in the glue guide box 510 and direct it to a specific location for flow and aggregation, which facilitates the subsequent centralized recycling and treatment of the glue. By setting the anti-stick coating, the glue can be effectively prevented from adhering to the inner wall of the glue guide box 510, making the glue easier to flow and clean.

[0038] Specifically, such as Figure 5 As shown, a reinforcing ring 7 is fixedly connected to the side of the support rod 507 near the limiting plate 501, and the surface of the reinforcing ring 7 is coated with anti-corrosion paint.

[0039] Specifically, such as Figure 1 As shown, a reinforcing base 8 is fixedly connected to the bottom of the pressure pump 503, and the side of the reinforcing base 8 away from the pressure pump 503 is fixedly connected to the top of the limiting plate 501.

[0040] In this embodiment: by setting the reinforcing ring 7, the structural strength of the connection between the support rod 507 and the limiting plate 501 is increased; by setting the anti-corrosion coating, the reinforcing ring 7 can be effectively protected from corrosion and its service life can be extended; by setting the reinforcing seat 8, the pressure pump 503 is provided with additional support and fixation, which enhances the installation stability of the pressure pump 503.

[0041] Working Principle: First, the user moves the support platform 1 to a suitable working position. Then, the user opens the glue storage tank 502 and adds sufficient glue. Next, the user places the cardboard box to be glued on the front side of the top of the work plate 4. At this time, the user turns on the power and starts the cylinder 307. The telescopic end of the cylinder 307 drives the clamping plate 308 to move towards the bottom of both sides of the cardboard box, gradually approaching the cardboard box. After the clamping plate 308 accurately clamps the cardboard box, the user turns off the power to the cylinder 307 to maintain the current clamping state. Then, the user turns on the power and starts the servo motor 303. The output shaft of machine 303 drives the lead screw 301 to rotate. Since the left slider 304 is threadedly connected to the lead screw 301, when the lead screw 301 rotates, the left slider 304 will move backward along the lead screw 301. At the same time, the left slider 304 drives the right slider 304 to move synchronously on the limit rod 302 through the connecting rod 305, so that the entire clamping mechanism 3 moves backward smoothly. When the clamping mechanism 3 moves to below the nozzle 505, the user turns on the power and starts the pressure pump 503. The pressure pump 503 starts to work, drawing out the glue in the glue storage tank 502 and pressurizing and delivering it to the nozzle 505. The nozzle 505 evenly sprays glue onto the top of the cardboard box. After the glue is sprayed, the user restarts the servo motor 303, causing the cardboard box to continue moving backward. When the top of the cardboard box contacts the bottom of the glue scraper 506, the scraper 506 scrapes off the excess glue from the top of the cardboard box. The scraped glue falls downward under gravity, passing through the glue leakage holes 509 on the work plate 4 and the support platform 1, and falls into the glue guide box 510 below. At this time, the user places an external collection device on the right side of the glue guide box 510 to collect the excess glue for later reuse. Afterward, the cardboard box continues to... During the backward movement, the top of the cardboard box contacts the glue scraper roller 508. With the help of the cardboard box moving backward, the glue scraper roller 508 rotates on the top of the cardboard box, further pressing the glue to make the glue more evenly distributed on the surface of the cardboard box. Finally, the glued cardboard box moves to the back of the work plate 4. The user turns on the cylinder 307 again and starts it, causing the cylinder 307 to release its grip on the cardboard box. The user collects the glued cardboard box, and then reverses the servo motor 303 to drive the clamping mechanism 3 back to the initial position, ready to perform the glue application operation on the next cardboard box. This cycle is repeated.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
