Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and more specifically, to a can bottom sealing cover device. Background Technology

[0002] A tank bottom sealing cover is a mechanical device used to accurately install and seal the bottom cover of a tank, ensuring the tank's airtightness and integrity. Existing tank bottom sealing cover equipment typically includes a conveying device, a bottom cover supply device, a pressing device, and a chassis structure. The chassis structure serves as the basic component supporting the tank, providing a stable platform for the tank during the bottom sealing process and ensuring the tank is in the appropriate operating position.

[0003] In the can sealing process, most of the chassis currently used are simple flat structures. When sealing cans such as beverage cans, if the can is full of liquid, some liquid is easily spilled during both clamping and placing of the can. Moreover, after pouring or other related processes, liquid residue often remains on the can surface. When the can is placed on the chassis, clamped and fixed, and then sealed, this spilled or residual liquid can easily contaminate the chassis. However, existing clamping devices often have many complex electrical structures, making it very inconvenient to wash the chassis after it becomes contaminated, thus affecting the normal progress of the overall sealing process and the smooth operation of subsequent related processes.

[0004] Therefore, we propose a tank bottom sealing cover device. Utility Model Content

[0005] This utility model provides a tank bottom sealing cover device. It features a support structure inside the sealing machine including a lifting component and a clamping component. A transparent cover encloses the cylinder and motor, effectively protecting the electrical components from external influences and facilitating the washing of potentially contaminated chassis. Furthermore, the arc-shaped groove inside the base allows for smooth water drainage after washing, and the clamping component, with interchangeable clamping rods of different lengths, adapts to different tank sizes. This solves the problems mentioned in the background art, namely: The chassis is easily contaminated by spilled or residual liquid from the tank, and the existing clamping device has a complex electrical structure that makes it inconvenient to clean. In addition, the equipment is difficult to adapt to tanks of various sizes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A tank bottom sealing cover device includes a sealing machine, the sealing machine having an internal support structure, the support structure including a support plate, the support plate being fixedly connected inside the sealing machine, and the support plate having a lifting component inside the support plate; A transparent cover is fixedly connected between the bottom of the support plate and the capping machine. A clamping assembly is provided on the top of the support plate. The top of the lifting assembly is used to support and place the tank. The clamping assembly is used to fix the tank. At the same time, the lifting assembly moves up and down to drive the tank to perform the bottom cap sealing operation.

[0007] Preferably, the lifting assembly includes a cylinder, which is fixedly connected inside the capping machine. A support plate is provided between the top of the cylinder and the inner wall of the capping machine. The piston rod of the cylinder passes through the top of the support plate and is fixedly connected to a base. The clamping assembly is located between the base and the support plate.

[0008] Preferably, the clamping assembly includes rotating rollers, and the three rotating rollers are movably connected inside the support plate. The rotating rollers are equipped with motors extending through the bottom of the support plate. The three motors are controlled to rotate simultaneously by the same system. The cylinder and the three motors are all located inside the transparent cover.

[0009] Preferably, the rotating roller is sleeved with a support rod extending from the top of the support plate, and the end of the support rod is provided with a clamping rod, which is located inside the base.

[0010] Preferably, the base has three arc-shaped grooves inside, and the clamping rods are located inside the arc-shaped grooves. The three clamping rods can move along the arc-shaped grooves to centrally position and clamp the tank at the top of the base.

[0011] Preferably, the support rod end is provided with a support sleeve, the outer wall of the clamping rod is provided with a bolt near the bottom, the clamping rod is threadedly connected to the inside of the support sleeve by the bolt, the radius of curvature of the arc-shaped sliding groove matches the length of the clamping rod, the radius of curvature remains unchanged when the clamping rod is replaced, and clamping rods of different lengths can be installed inside the support sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In a tank bottom sealing cover device, a transparent cover is fixedly connected between the bottom of the support plate and the sealing machine to cover and shield the cylinder and motor, so that the electrical components are not exposed. In this way, it can not only prevent external environmental factors from corroding and damaging key components such as cylinders and motors, extending their service life and ensuring the stability and reliability of the overall operation of the equipment, but also eliminate the need to worry about electrical failures caused by rinsing after the chassis is contaminated by liquid. This makes the cleaning and maintenance of the chassis convenient and safe, ensuring that the overall sealing process and subsequent related operations can be carried out normally, and the coordinated action of all components ensures the stable operation of the equipment.

[0013] 2. In a tank bottom sealing device, an arc-shaped groove is provided inside the base. When the base platform is rinsed with a water gun, the water can flow down along the arc-shaped groove. This can quickly and efficiently clean the stains and impurities on the base platform caused by spilled or residual liquid from the tank, preventing the accumulation of stains from affecting subsequent tank placement and sealing operations. It can also keep the base platform clean at all times, ensuring the stability of the tank placement and its accurate operating position.

[0014] 3. In a tank bottom sealing cover device, a transfer roller in the clamping assembly extends through the top of the support plate and is sleeved with a support rod. The end of the support rod is equipped with a clamping rod, which can be flexibly replaced and adapted to different lengths, enabling the device to handle tanks of various sizes. This enhances the device's versatility and applicability, avoiding the complex adjustments or incompatibility issues that may arise with existing equipment when dealing with different tanks. It reduces the cost for companies to replace equipment due to changes in tank specifications, and the coordinated operation of all parts improves the device's applicability.

[0017] 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.

[0018] Example Please see Figures 1-7 The diagram shows a tank bottom sealing cover device, including a sealing machine 1. The sealing machine 1 has a support structure 2 inside. The support structure 2 includes a support plate 22, which is fixedly connected inside the sealing machine 1. The support plate 22 has a lifting component 21 inside. A transparent cover 3 is fixedly connected between the bottom of the support plate 22 and the capping machine 1. The top of the support plate 22 is provided with a clamping component 23. The top of the lifting component 21 is used to support and place the tank. The clamping component 23 is used to fix the tank. At the same time, the lifting component 21 moves up and down to drive the tank to perform the bottom cover sealing operation.

[0019] When implementing, refer to Figure 7 As shown, the lifting assembly 21 includes a cylinder 211, which is fixedly connected inside the capping machine 1. A support plate 22 is provided between the top of the cylinder 211 and the inner wall of the capping machine 1. The piston rod of the cylinder 211 passes through the top of the support plate 22 and is fixedly connected to a base 210. The clamping assembly 23 is located between the base 210 and the support plate 22.

[0020] When the tank is to be placed, the cylinder 211 is in an initial static state. The base 210, which is fixedly connected to the top of its piston rod, provides a placement surface for the tank. The tank is placed stably on the base 210. At this time, the cylinder 211 supports the weight of the tank by its own firm installation and connection structure with other components.

[0021] Next, in the preparation stage before the bottom cover sealing operation, the clamping component 23 performs a center positioning clamping operation on the tank after the tank is placed, ensuring that the tank is always in the accurate center position when the lifting component 21 moves it up and down, avoiding tank offset or shaking, and ensuring that the entire bottom cover sealing operation can be carried out smoothly and accurately.

[0022] When entering the capping operation, if it is necessary to adjust the height of the tank to better adapt to the subsequent sealing process, the cylinder 211 starts to work under the drive of the corresponding power source, and the piston rod will move back and forth according to the command. Since the piston rod passes through the top of the support plate 22 and is connected to the base 210, the extension and retraction of the piston rod will drive the base 210 and the tank placed on the base 210 to move up and down, so that the tank reaches the appropriate height position to meet the requirements of sealing with the bottom cover.

[0023] See Figure 5As shown, the clamping assembly 23 includes three rotating rollers 230, all of which are movably connected inside the support plate 22. Each rotating roller 230 has a motor extending from the bottom of the support plate 22. The three motors are controlled by the same system to rotate simultaneously. The cylinder 211 and the three motors are all located inside the transparent cover 3. A support rod 231 is sleeved on the top of each rotating roller 230 extending from the support plate 22. A clamping rod 232 is located at the end of the support rod 231, inside the base 210.

[0024] Once the tank is placed on the base 210 of the lifting assembly 21, the clamping assembly 23 is activated to ensure the tank is in the accurate center position. At this time, the same control system simultaneously sends commands to the motors corresponding to the bottom of the three rollers 230, causing the three motors to rotate synchronously. Since the rollers 230 are movably connected inside the support plate 22, the motor drives the rollers 230 to rotate. The rotation of the rollers 230 causes the support rod 231, which is sleeved on the top of the support plate 22, to move accordingly. The clamping rods 232 at the end of the support rod 231 are located inside the base 210. As the support rod 231 moves, the three clamping rods 232 will move from different directions toward the position of the tank within the limited space of the base 210, eventually converging and fitting against the corresponding part of the tank, thus achieving the center positioning and clamping of the tank.

[0025] Considering that in existing technologies, the chassis are mostly simple planar structures, during the sealing process of the can, especially when the beverage can is full of liquid, liquid is prone to spillage during clamping or placing of the can, and liquid residue may remain on the surface of the can after pouring. This spilled or residual liquid will contaminate the chassis when the can is placed on it for sealing. Furthermore, existing clamping devices often have complex electrical structures, and without an effective protective structure like a transparent cover 3, the electrical components are often directly exposed. Once the chassis is contaminated and needs to be washed, the electrical structures must be carefully avoided, making operation extremely inconvenient.

[0026] In this solution, the transparent cover 3 encloses the cylinder 211 and three motors, among other key electrical components, providing excellent protection. It effectively blocks dust, moisture, and other impurities from the external environment, preventing them from corroding or damaging the electrical components, extending their lifespan, and ensuring the overall stability and reliability of the equipment. Furthermore, if the chassis is contaminated by spilled or residual liquid from the tank, the transparent cover 3 isolates and protects the electrical components, eliminating concerns about water splashing onto the components and causing electrical malfunctions during chassis cleaning. Operators can directly clean the chassis, making subsequent chassis maintenance convenient and safe, ensuring the smooth and continuous operation of the overall sealing process and related procedures.

[0027] The base 210 has three arc-shaped grooves inside, and the clamping rods 232 are located inside the arc-shaped grooves. The three clamping rods 232 can move along the arc-shaped grooves to centrally position and clamp the tank at the top of the base 210.

[0028] When the can is placed on the base 210 of the lifting assembly 21, the clamping assembly 23 is activated, and the three rollers 230 rotate under the drive of the motor, thereby driving the support rod 231 to move. When the clamping rod 232 at the end of the support rod 231 moves to prepare for positioning and clamping the can, the three arc-shaped grooves inside the base 210 provide a guide path for the movement of the clamping rod 232. Since the clamping rod 232 is located inside the groove, it can only slide along the predetermined arc-shaped trajectory of the groove. Because the three arc-shaped grooves are arranged in a specific layout and are evenly distributed in the base 210, when the clamping rod 232 moves along its corresponding arc-shaped groove, it can converge towards the can from different directions and always maintain an accurate relative positional relationship, so that the three clamping rods 232 can finally stably and accurately fit against the corresponding part of the can, achieving center positioning and clamping of the can.

[0029] Furthermore, the structure of the base 210 with its arc-shaped groove facilitates cleaning and maintenance. In actual production, spilled or residual liquids from the tank may remain on the surface of the base 210. When cleaning is required, the base 210 can be rinsed with a water gun or similar tool. The water generated during rinsing flows smoothly down the arc-shaped groove, preventing the accumulation of stains on the base 210 and ensuring that the base 210 remains relatively clean. This contributes to the stability of subsequent tank placement and the accuracy of the bottom cap sealing operation.

[0030] Additionally, see Figure 6 As shown, the end of the support rod 231 is provided with a support sleeve 2310, and the outer wall of the clamp 232 is provided with a bolt 2320 near the bottom. The clamp 232 is threadedly connected to the inside of the support sleeve 2310 by the bolt 2320. The radius of curvature of the arc-shaped sliding groove matches the length of the clamp 232. When the clamp 232 is replaced, its radius of curvature remains unchanged. The support sleeve 2310 can install clamps 232 of different lengths.

[0031] When center positioning and clamping operations are required for tanks of different sizes and specifications, adjustments to the clamping roller 232 are involved. The support sleeve 2310 at the end of the support rod 231 provides a basic structure for the installation of the clamping roller 232, and the bolt 2320 on the outer wall of the clamping roller 232 near the bottom is adapted to the internal thread of the support sleeve 2310.

[0032] During installation, align the end of the clamp 232 with the bolt 2320 with the inside of the support sleeve 2310. By rotating the clamp 232, the bolt 2320 is gradually screwed into the thread of the support sleeve 2310, thereby connecting the clamp 232 to the support sleeve 2310. Since there is enough space inside the support sleeve 2310 to accommodate clamps 232 of different lengths, when dealing with tanks of different sizes, simply select the corresponding length of clamp 232 and install it into the support sleeve 2310 according to the above threaded connection method.

[0033] By changing the clamping rollers 232 to different lengths, the range of extension of the clamping rollers 232 can be changed, so that they can better fit the outer contour of different tanks and accurately position and clamp tanks of various sizes from different directions, ensuring that tanks of different specifications can be stably fixed in the appropriate center position during the entire bottom sealing operation.
