Description

Technical Field

[0001] This utility model relates to the field of can sealing equipment technology, specifically a fully automatic can sealing machine with automatic deviation correction function. Background Technology

[0002] A can sealing machine is a mechanical device used to seal the mouths of containers such as metal cans, glass cans, and plastic cans containing products. Traditional can sealing operations mainly rely on manual labor, but manual operation is extremely inefficient, only able to seal dozens to hundreds of cans per hour, which is difficult to meet the needs of large-scale production. Especially during peak production seasons in the food and beverage industries, there is often a problem of insufficient production capacity. At the same time, the sealing quality of manual can sealing is unstable, affected by factors such as the operator's skill level and physical condition, which can easily lead to incomplete sealing, resulting in leakage and deterioration of the product inside the can, causing economic losses. It also cannot guarantee the uniformity of product quality. Therefore, can sealing equipment needs to develop towards automation.

[0003] In the prior art, utility model patent application number CN202321597248.1 discloses an automatic can sealing machine, including a housing, a control panel on the housing, a control system connected to the control panel, a support platform at the bottom front of the housing, a tray detachably connected to the support platform, a positioning structure between the tray and the support platform, a tooling groove on the top of the tray for fitting and inserting the bottom of the can, and a punch that can move vertically up and down directly above the tooling groove. The punch and the tray constitute a stamping mechanism for pressing and sealing the can and end cap. The punch is connected to an electrically driven stamping drive, which can automatically complete the stamping action according to instructions. This automatic can sealing machine utilizes electrically driven automatic stamping, saving time and labor. Combined with a precise alignment and easy disassembly and replacement of the stamping mechanism, it can meet the sealing needs of cans of various heights.

[0004] The aforementioned patent discloses an automatic can sealing machine structure that uses an electrically driven stamping actuator to control the automatic stamping of the punch, replacing the existing automatic can sealing machine structure that requires manual pressing. However, the automation level of this automatic can sealing machine is not high, requiring workers to place the cans one by one, resulting in unsatisfactory improvement in sealing efficiency, which needs further improvement.

[0005] The purpose of this invention is to provide a fully automatic can sealing machine with automatic deviation correction function, which aims to improve the problems of existing automatic can sealing machines, such as low automation level, limited can sealing efficiency, excessive reliance on manual operation and lack of automatic can deviation correction function.

[0006] This utility model is implemented as follows: A fully automatic can sealing machine with automatic deviation correction function includes a can sealing machine body and a deviation correction device. The can sealing machine body includes a conveyor belt, a material picking device, and a can sealing device. The material picking device is rotatably arranged above the conveyor belt and includes a material picking disc with multiple material picking slots arranged along its circumference. The can sealing device is located above one of the material picking slots but not above the conveyor belt. The deviation correction device has a deviation correction lever elastically arranged therein, which elastically presses against the notch of the material picking slot corresponding to the can sealing device.

[0007] Preferably, the middle position of the conveyor belt is located on the can sealing machine body, and the upper end surface of the conveyor belt is flush with the upper end surface of the can sealing machine body; the conveyor belt extends to the outside of the can sealing machine body.

[0008] Preferably, the upper end face of the can sealing machine body is provided with a settling groove, and the conveyor belt is set in the settling groove.

[0009] Preferably, the lower ends of the conveyor belt are symmetrically provided with support legs, and the upper ends are symmetrically provided with protective edges on both sides.

[0010] Preferably, the can sealing machine body is provided with a support frame located above the conveyor belt, and the support frame is provided with an installation sleeve located above the conveyor belt. A rotating shaft is rotatably installed in the installation sleeve. The upper end of the rotating shaft is connected to a motor, and the lower end is connected to a material handling device.

[0011] Preferably, the material handling device includes a connecting plate and a connecting rod. The upper end face of the connecting plate is connected to the lower end of the rotating shaft, and the lower end face of the connecting plate is provided with a material handling plate via the connecting rod. The connecting plate is provided with through slots corresponding to each material handling slot, and the can sealing device can extend into the through slots.

[0012] Preferably, it also includes an anti-detachment structure, the shape of which is adapted to the outer arc of the feeding tray; the can sealing machine body is provided with an anti-detachment structure, which is adapted to the feeding trough of the corresponding can sealing device.

[0013] Preferably, the correction device includes a mounting base, the correction lever is elastically rotatably mounted on the mounting base, and the mounting base is mounted on the upper end face of the can sealing machine body.

[0014] Preferably, a vertical mounting rod is fixedly installed on the mounting base, and the end of the correction lever near the feed of the conveyor belt is rotatably mounted on the mounting rod.

[0015] Preferably, the correction device further includes a spring, and the mounting base has a vertical plate located on the back of the correction lever. One end of the spring is fixedly connected to the vertical plate, and the other end is fixedly connected to the back of the correction lever.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the coordinated design of a conveyor belt and a rotating material-picking device, ensures that the conveyor belt continuously transports cans to the material-picking area. The structure extending to the outside of the can-sealing machine body can connect with the front-end feeding process, achieving continuous can supply. Multiple material-picking slots are evenly arranged along the circumference of the material-picking disc. Combined with a motor-driven rotating shaft, the automated process of can picking, moving, delivering to the sealing position, and discharging cans can be completed simultaneously, without manual intervention. Compared to the efficiency of traditional manual can sealing (tens to hundreds of cans per hour) and semi-automatic equipment relying on manual can placement, this equipment achieves full automation of can conveying, transferring, and sealing, effectively improving the efficiency of the can-sealing machine.

[0017] 2. This utility model is equipped with an elastic correction device. The correction lever is elastically pressed against the notch of the material receiving slot of the corresponding sealing device by a spring. When the can rotates to the sealing position with the material receiving plate, if the position is offset due to conveying or transfer, the correction lever will push the can under the action of the spring force to keep it in the center position of the material receiving slot, ensuring that the can and the sealing device are vertically and accurately aligned.

[0021] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details: Example 1 like Figure 1 , Figure 4 and Figure 5As shown, a fully automatic can sealing machine with automatic deviation correction function includes a can sealing machine body 1 and a deviation correction device 5. The can sealing machine body 1 includes a conveyor belt 2, a material feeding device 3, and a can sealing device 4. The can sealing device 4 includes a can sealing head, can sealing rollers, and a drive mechanism. The can sealing head is located above the position corresponding to the material feeding trough 302, and its axis is on the same vertical line as the axis of the material feeding trough 302, ensuring uniform pressure when sealing the can. The can sealing head is made of Cr12MoV mold steel, which has been quenched to a hardness of HRC58-62, and has high wear resistance and compressive strength. A sealing gasket is provided on the lower end face of the can sealing head. The sealing gasket is made of silicone rubber with a thickness of 3-5mm, which can ensure the sealing performance during can sealing and prevent leakage of materials inside the can. The can sealing rollers are located on both sides of the can sealing head and work together with the can sealing head to complete the can sealing operation. The sealing rollers are made of 45# steel with a chrome-plated surface, 0.05-0.1mm thick, improving surface hardness and wear resistance.

The transmission gears have a module of 2 and 20-30 teeth, ensuring smooth transmission and high efficiency. The conveyor belt 2 is positioned at the middle of the can sealing machine body 1, with its upper surface flush with the upper surface of the can sealing machine body 1. The conveyor belt 2 extends to the outside of the can sealing machine body 1. A seating groove 101 is formed on the upper surface of the can sealing machine body 1, and the conveyor belt 2 is seated in the seating groove 101. Support legs 201 are symmetrically arranged on the lower surfaces of both ends of the conveyor belt 2, and protective edges 202 are symmetrically arranged on both sides of the upper surface. The depth of the seating groove 101 is adapted to the thickness of the conveyor belt 2, ensuring that the upper surface of the conveyor belt 2 is precisely flush with the upper surface of the can sealing machine body 1 after it is seated in it. Wear-resistant strips made of polyurethane with a thickness of 3-5mm are provided on both sides of the inner wall of the seating groove 101 to reduce friction loss between the conveyor belt 2 and the groove wall during operation, thereby extending the service life of the conveyor belt 2 and the seating groove 101. Meanwhile, guide ramps are provided at both ends of the trough 101, with the ramps forming an angle of 15-20° with the horizontal plane, which facilitates the removal of the conveyor belt 2 during installation and maintenance.

[0022] like Figure 1 , Figure 3 and Figure 5As shown, the material taking device 3 is rotatably positioned above the conveyor belt 2. The material taking device 3 includes a material taking disc 301, on which multiple material taking slots 302 are arranged along its circumference. The sealing device 4 is positioned above one of the material taking slots 302, but not above the conveyor belt 2. The sealing machine body 1 is provided with a support frame 102 located above the conveyor belt 2. The support frame 102 is provided with an installation sleeve 103 located above the conveyor belt 2. A rotating shaft 7 is rotatably installed in the installation sleeve 103. The inner wall of the installation sleeve 103 is provided with a bearing mounting groove, in which a deep groove ball bearing of model 6205 is installed. The inner ring of the bearing is interference-fitted with the rotating shaft 7, and the outer ring is transition-fitted with the bearing mounting groove of the installation sleeve 103. Sealing caps are provided at both the upper and lower ends of the mounting sleeve 103. The sealing caps are made of plastic and are connected to the mounting sleeve 103 by a snap-fit ​​mechanism. Dustproof rings are installed inside the sealing caps to effectively prevent dust and impurities from entering the mounting sleeve 103, avoiding wear on the bearings and rotating shaft 7, and ensuring smooth rotation of the rotating shaft 7. A motor 6 is connected to the upper end of the rotating shaft 7, and a material-collecting device 3 is connected to the lower end. The material-collecting device 3 includes a connecting plate 303 and a connecting rod 305. The upper end of the connecting plate 303 is connected to the lower end of the rotating shaft 7, and a material-collecting disc 301 is provided on the lower end of the connecting plate 303 via the connecting rod 305. The connecting plate 303 has through slots 304 corresponding to each material-collecting groove 302, and the sealing device 4 can extend into the through slots 304. Additionally, it includes an anti-detachment structure 8, the shape of which matches the outer arc of the feeding tray 301; the can sealing machine body 1 is equipped with the anti-detachment structure 8, which matches the feeding trough 302 of the corresponding can sealing device 4. The diameter of the feeding tray 301 is determined according to the production efficiency of the can sealing machine and the size of the can being sealed, generally 300-500mm, and the thickness is 15-20mm. The feeding troughs 302 are evenly distributed along the circumference of the feeding tray 301, with a quantity of 4, the specific number of which can be adjusted according to actual production needs. The shape of the material inlet trough 302 is adapted to the annular shape of the sealed can, generally a semi-circular trough, to ensure that the can moves into the material inlet trough 302 by the conveyor belt. The inner wall of the material inlet trough 302 is provided with a rubber pad layer with a thickness of 2-3mm, which can increase the friction between the can and the material inlet trough 302, and at the same time avoid the can directly contact the inner wall of the material inlet trough 302 and cause wear. Then, as the material inlet device 3 rotates, it drives the can to move to the bottom of the sealing device 4. During the movement, the outer side of the material inlet trough 302 is sealed by the anti-detachment structure 8 to prevent it from falling off.

[0023] like Figure 1 , Figure 2 and Figure 6As shown, the correction device 5 includes a correction lever 503 that is elastically mounted. The correction lever 503 elastically presses against the notch in the feeding trough 302 corresponding to the sealing device 4. The correction device 5 includes a mounting base 501, on which the correction lever 503 is elastically rotatably mounted. The mounting base 501 is mounted on the upper surface of the sealing machine body 1. A vertical mounting rod 502 is fixedly mounted on the mounting base 501, and the end of the correction lever 503 near the feed of the conveyor belt 2 is rotatably mounted on the mounting rod 502. The correction device 5 also includes a spring 504. The mounting base 501 has a vertical plate located on the back of the correction lever 503. One end of the spring 504 is fixedly connected to the vertical plate, and the other end is fixedly connected to the back of the correction lever 503. By flexibly setting the correction lever 503, when the can body moves to the bottom of the sealing device 4 via the material receiving device 3, the correction lever 503 abuts against the can body, ensuring that the can body is always centered in the material receiving trough 302, thus achieving vertical alignment between the can body and the sealing device 4. Furthermore, the flexible setting of the correction lever 503 does not affect the normal movement of the can body driven by the material receiving device 3. A protective rubber pad is provided at the point where the correction lever 503 abuts against the can body to prevent damage to the can body. The spring force is selected with an appropriate magnitude to ensure that the correction lever 503 can push the can body to the centered position without causing excessive compressive force.
