Description

Technical Field

[0001] This utility model relates to the field of glue injection device technology, and specifically discloses a glue injection device for the bottom of a food can. Background Technology

[0002] Sealing adhesive injection at the bottom of the can involves injecting a portion of sealing adhesive into the groove of the bottom cover. Its function is to fill the gap in the roll-up of the bottom cover, ensuring the sealing and leak-proof performance of the bottom of the can.

[0003] Chinese Patent No. CN207138226U discloses a can bottom cover glue injection equipment and its feeding device, which solves the problem that the feeding of common can bottom cover glue injection equipment relies on manual labor and has low production efficiency. The key technical points are: a base; a working platform set on the base; a hopper set on one side of the working platform for storing bottom covers; a sliding seat slidably connected to the working platform and connected at one end to the hopper; a driving mechanism set on the base for driving the sliding seat to slide on the working platform; a glue injection table set on the working platform corresponding to the position of a glue injection mechanism; and a plurality of conveying components set on the sliding seat to drive the bottom cover to be transported on the working platform when the sliding seat moves, so as to achieve automatic feeding and improve production efficiency.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-4A food can bottom glue injection device includes a fixed frame 1, a glue injection structure is provided on one side above the fixed frame 1, a rotating frame 3 is provided in the middle of the upper end face of the fixed frame 1, a stepper motor 301 with its output end fixedly connected to the rotating frame 3 is installed in the middle of the bottom end of the fixed frame 1, positioning structures with the same structure are symmetrically provided on the left and right sides of the upper end face of the fixed frame 1, and a drying structure symmetrically provided with the glue injection structure is provided above the fixed frame 1 through a driving structure.

[0025] The positioning structure includes a turntable 2 rotatably connected to the upper end face of the fixed frame 1, a servo motor 206 installed at the bottom end of the fixed frame 1 and whose output end is fixedly connected to the turntable 2, a positioning column 201 fixedly connected to the upper end face of the turntable 2, a plurality of adsorption tubes 203 arranged in a ring on the upper end face of the turntable 2 and located outside the positioning column 201, an adsorption plate 204 connected to the outer wall of the plurality of adsorption tubes 203 near the positioning column 201, and a micro suction pump 205 connected to the outer wall of one of the adsorption tubes 203.

[0026] The drying structure includes a drying cylinder 5 located at the bottom of one side of the rotating frame 3, a heating tube 502 installed at the top of the inner wall of the drying cylinder 5, an air cavity 503 located on the inner wall of the drying cylinder 5, an air outlet 504 extending through the outer wall of the air cavity 503, a fan 505 installed on the outer wall of the drying cylinder 5 and connected to the air outlet and the air cavity 503, and a second electric push rod 501 installed on the upper surface of the rotating frame 3 and whose output end is fixedly connected to the drying cylinder 5.

[0027] In this embodiment: the can to be injected with glue is placed on the outer wall of the positioning post 201. The can is confined between the positioning post 201 and multiple adsorption tubes 203. Multiple annularly distributed adsorption tubes 203 are connected to form a negative pressure circuit. The adsorption plate 204 adsorbs and fixes the can from multiple points on the side wall of the can, avoiding the deformation of the can caused by traditional mechanical clamping. At the same time as the glue is injected, the servo motor 206 drives the turntable 2 to rotate. As the turntable 2 drives the positioning post 201 and the can to rotate, the glue injection tube 402 can inject glue into the bottom of the can.

[0028] Stepper motor 301 drives rotating frame 3 to precisely rotate between the glue injection and drying stations, enabling timely drying after glue injection. Simultaneously, another tank can be dried. The drying cylinder 5 integrates heating tube 502 and air cavity 503. Fan 505 blows hot air evenly to the bottom of the tank through the porous air cavity 503, achieving rapid and thorough curing of the glue and avoiding localized overheating. Through the symmetrically arranged turntable 2, positioning column 201, and adsorption structure, the dual-station synchronous operation is achieved, allowing the other station to dry the tank while one station is injecting glue, significantly improving production efficiency.

[0029] As a technical optimization of this utility model, the glue injection structure includes a connecting plate 403 disposed at the bottom of the other side of the rotating frame 3, a glue cavity 401 installed at the bottom of the connecting plate 403, a glue injection tube 402 connected to the bottom of the glue cavity 401, and a first electric push rod 4 installed on the upper surface of the rotating frame 3, with its output end fixedly connected to the connecting plate 403.

[0030] In this embodiment: the first electric push rod 4 drives the connecting plate 403 to move downward, causing the glue cavity 401 and the glue injection tube 402 to move vertically, precisely controlling the distance between the glue injection head and the bottom of the can, and ensuring accurate glue injection.

[0031] As a technical optimization of this utility model, the positioning structure also includes an annular groove 202 opened on the upper surface of the turntable 2 and located at the bottom edge of the positioning column 201.

[0032] In this embodiment, the annular groove 202 can limit the bottom edge of the tank, preventing the tank from shifting during rotation and enhancing the reliability of adsorption and fixation.

[0033] As a technical optimization of this utility model, the diameter of the drying cylinder 5 is larger than the distance between the two adsorption tubes 203 that are arranged opposite to each other.

[0034] In this embodiment, by making the diameter of the drying cylinder 5 larger than the distance between the two adsorption tubes 203 that are arranged opposite each other, the drying cylinder 5 can smoothly cover the outside of the positioning column 201 and the adsorption tube 203, ensuring complete coverage of the glue injection area at the bottom of the tank and improving drying consistency.

[0035] As a technical optimization of this utility model, multiple adsorption tubes 203 are connected by pipes.

[0036] In this embodiment, the adsorption force can penetrate through each adsorption tube 203 by connecting multiple adsorption tubes 203 through pipes, so that the adsorption tubes 203 can work normally.

[0037] As a technical optimization of this utility model, a controller is installed on the outer wall of the fixing frame 1, and the micro suction pump 205, servo motor 206, stepper motor 301, fan 505, first electric push rod 4 and second electric push rod 501 are all electrically connected to the controller.

[0038] In this embodiment, the micro suction pump 205, servo motor 206, stepper motor 301, fan 505, first electric actuator 4 and second electric actuator 501 can be controlled to work normally by the controller.

[0039] The working principle and usage process of this utility model are as follows: The can to be injected with glue is placed on the outer wall of the positioning post 201. The can is located between the positioning post 201 and multiple adsorption tubes 203. Multiple annularly distributed adsorption tubes 203 are connected to form a negative pressure circuit. The adsorption plate 204 adsorbs and fixes the can from multiple points on the side wall of the can. Then, the first electric push rod 4 drives the connecting plate 403 to move down, causing the glue cavity 401 and the glue injection tube 402 to move vertically. Glue is accurately injected through the glue injection tube 402. At the same time as the glue is injected, the servo motor 206 drives the turntable 2 to rotate. As the turntable 2 drives the positioning post 201 and the can to rotate, the glue injection tube 402 can inject glue all over the bottom of the can.

[0040] After the glue is applied, the stepper motor 301 drives the rotating frame 3 to rotate precisely between the glue application and drying stations, causing the drying cylinder 5 to rotate to the left to dry the glued can. The glue application structure then rotates to the right to apply glue to another can, achieving timely drying after glue application. Simultaneously, the other can be dried while glue application is being performed. The drying cylinder 5 integrates a heating tube 502 and an air chamber 503. The fan 505 blows hot air evenly to the bottom of the can through the porous air chamber 503, achieving rapid and thorough curing of the glue and avoiding localized overheating. The symmetrically arranged turntable 2, positioning column 201, and adsorption structure enable simultaneous operation of the two stations, allowing the other station to dry the can while one station is applying glue, significantly improving production efficiency.

Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
