Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and more specifically, to an automatic loading and unloading cardboard box processing glue application device. Background Technology

[0002] Cardboard boxes are indispensable in modern life and production. Whether for loading and transporting goods or for packaging and storing items, cardboard boxes are essential. In particular, paper packaging boxes are both environmentally friendly and convenient, making them the preferred and most commonly used outer packaging device for the general public. Cardboard is die-cut, creasing, and gluing to make cardboard boxes. Many steps in cardboard box production usually require the use of glue, which is very important in the cardboard box production process. As a result, cardboard box gluing equipment has emerged.

[0003] Among them, the patent with announcement number CN223187112U discloses an automatic loading and unloading cardboard box processing glue application device, including a base, a conveyor belt driven on the base, two sets of positioning components symmetrically arranged on both sides of the conveyor belt at one end of the base, a glue tank slidably arranged vertically above the conveyor belt, a scraper and stirring component slidably arranged inside the glue tank, a second scraper rotatably arranged on the lower end face of the glue tank away from the positioning components, and multiple glue dispensing components fixedly arranged on the lower end face of the glue tank; each glue dispensing component includes a fixed head, a glue dispensing head rotatably arranged below the fixed head, and a detachable rubber ring, a metal wire filter screen, and a glue discharge valve arranged inside the glue dispensing head;

[0004] When in use, this structure allows production personnel to control the device to apply glue only to a portion of the cardboard surface through multiple glue dispensing components. The scraping and stirring components enable the device to automatically scrape and stir the glue in the glue tank during operation, effectively preventing problems such as clumping and clogging. However, this structure cannot adjust the angle of the cardboard box during the glue application process, which limits its guiding glue application. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic loading and unloading cardboard box processing glue application device, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: an automatic loading and unloading cardboard box processing glue application device, including a base, on which a material guiding processing component for realizing cardboard box conveying and positioning is assembled, and a glue application execution component for performing glue application on the cardboard box.

[0007] The material guiding and processing assembly includes a first conveyor belt fixedly installed on the top of the base. The first conveyor belt has a second conveyor belt corresponding to each end of its conveying direction. Each second conveyor belt is vertically fixed with a column between it and the first conveyor belt. The tops of the two columns are rotatably connected to a third conveyor belt through a rotating shaft. The conveying direction of the third conveyor belt is the same as that of the first conveyor belt. The side of each third conveyor belt away from the column is integrally formed with a baffle along its length to limit the side of the carton and prevent the carton from shifting.

[0008] The adhesive application assembly includes a reinforcing frame that is detachably fixed to the base by bolts. The reinforcing frame has a gate-shaped structure and spans directly above the first conveyor belt. Two parallel electric slide rails are symmetrically fixed to the side of the reinforcing frame facing the first conveyor belt. Each electric slide rail is slidably connected to a connecting plate whose position can be adjusted along the length of the electric slide rail.

[0009] Optionally, in one possible implementation, the bottom of the first conveyor belt, the second conveyor belt, and the third conveyor belt are each equipped with a motor for providing driving force. The motor is fixedly mounted on the base by a motor bracket, and the output shaft end of each motor is fitted with a drive pulley. The rotating shaft end of the first conveyor belt, the second conveyor belt, and the third conveyor belt is fitted with a driven pulley. A belt for power transmission is fitted between the drive pulley and the corresponding driven pulley to drive the first conveyor belt, the second conveyor belt, and the third conveyor belt to operate synchronously.

[0010] Optionally, in one possible implementation, an electric push rod is hinged to the side of the column near the third conveyor belt for driving the third conveyor belt to rotate around the top pivot of the column to achieve angle adjustment. The fixed end of the electric push rod is hinged to the upper surface of the base through a hinge seat, and the telescopic end of the electric push rod is hinged to the middle position of the bottom of the third conveyor belt through a ball joint. The telescopic stroke of the electric push rod can meet the angle adjustment between the third conveyor belt and the horizontal plane. The glue applicator body for dispensing glue and completing the glue application action is fixedly installed on the side of the connecting plate away from the electric slide rail by bolts.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] An electric push rod, hinged between the column and the third conveyor belt, allows for precise adjustment of the angle between the third conveyor belt and the horizontal plane within a certain range. When processing flat, standard cardboard boxes, the angle can be adjusted to be horizontal to ensure stable horizontal conveying. When processing irregularly shaped cardboard boxes with inclined surfaces, the angle can be adjusted to maintain a suitable angle between the glued surface of the cardboard box and the glue outlet of the glue applicator, preventing uneven glue application due to glue flowing on the inclined surface. This effectively covers the glue application needs of cardboard boxes of different sizes and solves the limitations of traditional guided glue application devices.

[0013] By using a baffle integrally formed along the length of the third conveyor belt on the side away from the column, a rigid limit can be formed on the side of the carton during the conveying process, preventing the carton from shifting laterally due to fluctuations in conveyor belt speed and differences in surface friction. Furthermore, the device constructs a fully automated production line for loading, conveying, gluing, and unloading through the coordinated conveying of the first, second, and third conveyor belts, combined with the power transmission of the motor and belt. This eliminates the need for manual intervention in carton transfer and positioning, thereby improving gluing production efficiency. Attached Figure Description

[0019] 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.

[0020] The automatic loading and unloading cardboard box processing glue application device disclosed in the embodiments, such as Figure 1As shown, its core structure includes a base 1, a material guiding and processing component, and a glue application execution component. The base 1 ensures the overall load-bearing stability of the device; the material guiding and processing component is assembled in the central area of ​​the base 1 and is used to complete the automatic feeding, conveying, positioning, and unloading of cartons; the glue application execution component is positioned directly above the material guiding and processing component and is used to accurately complete the glue application operation on the cartons.

[0021] like Figure 1 , Figure 3 As shown, the first conveyor belt 2 is bolted to the middle of the top of the base 1. The surface of the conveyor belt is made of anti-slip rubber to increase the friction with the carton and prevent the carton from slipping during transportation. Second conveyor belts 3 are respectively installed at both ends of the first conveyor belt 2 along its conveying direction. The structure of the second conveyor belts 3 is the same as that of the first conveyor belt 2, and the two second conveyor belts 3 are symmetrically distributed about the central axis of the first conveyor belt 2, realizing continuous conveying of carton loading, processing, and unloading.

[0022] A vertical column 4 is welded between each second conveyor belt 3 and the first conveyor belt 2 to support the third conveyor belt 5. The top of the column 4 is rotatably connected to the third conveyor belt 5 via a deep groove ball bearing. The conveying direction of the third conveyor belt 5 is the same as that of the first conveyor belt 2, and a baffle 6 is integrally formed along the length of the third conveyor belt 5 on the side away from the column 4. The baffle 6 is made of wear-resistant plastic and can limit the side of the carton during the carton conveying process to prevent the carton from shifting due to changes in conveying speed or external interference, ensuring that the carton can be accurately conveyed to the glue coating area.

[0023] like Figure 2 , Figure 3 As shown, each of the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 5 is equipped with a Y100L-2 motor 11 at its bottom. The motor 11 is fixedly mounted on the lower surface of the base 1 via an L-shaped motor bracket. Each motor 11 has a drive pulley connected to its output shaft via a key, while the driven pulleys are correspondingly fitted to the rotating shafts of the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 5. A belt 12 is fitted between the drive pulley and the driven pulley. When the motor 11 starts, power is transmitted to the rotating shafts of each conveyor belt via the belt 12, driving the first conveyor belt 2, the second conveyor belt 3, and the third conveyor belt 5 to operate synchronously.

[0024] like Figure 1 , Figure 2As shown, each column 4 has a DTZ300 electric push rod 13 hinged to one side near the third conveyor belt 5 via a hinged joint. The fixed end of the electric push rod 13 is hinged to the upper surface of the base 1, and the telescopic end is hinged to the middle position of the bottom of the third conveyor belt 5 via a ball joint. When it is necessary to adjust the angle of the third conveyor belt 5, a command is sent to the electric push rod 13 through the PLC controller. The telescopic end of the electric push rod 13 extends or retracts, pushing the third conveyor belt 5 to rotate around the pivot at the top of the column 4, thereby changing the angle between the third conveyor belt 5 and the horizontal plane. For example, when applying glue to a flat cardboard box, the angle is adjusted to 0° to ensure that the cardboard box is conveyed horizontally; when applying glue to an irregularly shaped cardboard box with an inclined surface, the angle is adjusted to 15° to keep the inclined glue-applying surface of the cardboard box parallel to the glue outlet of the glue applicator body 10, improving the glue-applying quality.

[0025] like Figure 1 , Figure 2 As shown, the core of the adhesive application assembly consists of the reinforcing frame 7 and the adhesive applicator body 10. The reinforcing frame 7 has a gate-shaped structure. The bottom of the reinforcing frame 7 is fixedly connected to the base 1 by bolts, which are distributed at the four corners of the bottom of the reinforcing frame 7 to ensure that the reinforcing frame 7 does not shake during the adhesive application process.

[0026] Two HGW20 electric slide rails 8 are symmetrically fixed on one side of the reinforcing frame 7 facing the first conveyor belt 2. The two electric slide rails 8 are arranged in parallel, and their length direction is perpendicular to the conveying direction of the first conveyor belt 2. Each electric slide rail 8 is slidably connected to a connecting plate 9, which is made of aluminum alloy. The connecting plate 9 cooperates with the guide rail of the electric slide rail 8 through a slider, and can slide along the length direction of the electric slide rail 8. The start, stop and sliding distance are controlled by a PLC controller, thereby realizing the precise adjustment of the position of the connecting plate 9.

[0027] The glue applicator body 10 is bolted to the side of the connecting plate 9 away from the electric slide rail 8. The glue applicator body 10 is a DJ-200 hot melt glue applicator, and its outlet diameter can be changed according to requirements. The outlet of the glue applicator body 10 faces the conveying plane of the first conveyor belt 2. When the carton is conveyed to the glue applicator area, the glue applicator body 10 is moved in the back-and-forth direction by adjusting the electric slide rail 8, which can achieve glue application to different width positions of the carton. At the same time, in conjunction with the conveying speed of the first conveyor belt 2, continuous linear glue application or intermittent glue application to the carton can be achieved to meet diverse glue application process requirements.

[0028] The specific working principle is as follows: according to the specifications of the carton to be processed, the parameters are set through the PLC controller: adjust the speed of motor 11, set the conveying speed of the first conveyor belt 2, the second conveyor belt 3 and the third conveyor belt 5; control the electric push rod 13 to adjust the angle between the third conveyor belt 5 and the horizontal plane to 0° for ordinary rectangular cartons; adjust the electric slide rail 8 to move the glue outlet of the glue applicator body 10 to the preset glue applicator position on the carton, and at the same time set the glue output of the glue applicator body 10.

[0029] Place the cardboard box to be coated on the second conveyor belt 3 at the feed end of the device, start the device, and the motor 11 drives each conveyor belt to run through the belt 12. The cardboard box is transported to the third conveyor belt 5 under the drive of the second conveyor belt 3, and its position is kept stable under the limiting action of the baffle 6. Then it smoothly transitions to the first conveyor belt 2.

[0030] When the carton is conveyed by the first conveyor belt 2 to the area directly below the glue applicator body 10, the glue applicator body 10 starts and outputs glue from the glue outlet to the surface of the carton. At the same time, the first conveyor belt 2 continues to convey the carton, realizing continuous glue application to the carton. If glue needs to be applied to multiple positions of the carton, the electric slide rail 8 can be controlled by the PLC controller to move the glue applicator body 10, and the glue application operation at each position can be completed in sequence.

[0031] After the glue is applied, the cartons are conveyed by the first conveyor belt 2 to the third conveyor belt 5 at the discharge end, then transitioned to the second conveyor belt 3 on the right, and finally conveyed by the second conveyor belt 3 to the receiving area outside the device, completing the entire automatic loading and unloading and glue application process.

[0032] 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, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
