Description

Technical Field

[0001] This utility model relates to the field of can sealing, and in particular to a fully automatic PET can sealing device. Background Technology

[0002] Sealing refers to the process of sealing the opening of a container (such as a can or bottle) during the packaging process to ensure that the contents do not leak, become contaminated, or deteriorate.

[0003] A fully automatic PET can sealing device is a device used to automatically seal PET cans.

[0004] The existing fully automatic PET can sealing device has the following shortcomings:

[0005] Canned foods, having met commercial aseptic standards, can be stored at room temperature for extended periods. During production, sealing devices are required to seal the cans. However, existing technologies often suffer from difficulties in securing the cans, leading to them tipping over during the sealing process. This not only disrupts normal operations but may also affect the sealing performance, increase the defect rate, and even waste raw materials due to tipping. All of this negatively impacts production efficiency and product quality, necessitating urgent improvement and optimization. Utility Model Content

[0006] This invention can not only adapt to PET cans of different diameters, significantly enhancing the equipment's compatibility with cans of various specifications, avoiding frequent equipment changes and effectively reducing production costs, but also achieves clamping and fixing of the cans to prevent displacement or tipping during subsequent operations, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a fully automatic PET can sealing device, comprising an integral mechanism, with a support mechanism fixedly installed at the bottom of the integral mechanism; the integral mechanism includes a fixing plate, a bidirectional screw is movably inserted into the inner wall of the fixing plate, a set of first sliders is slidably connected to the inner wall of the fixing plate, a set of connecting plates is fixedly connected to the bottom of the first sliders, a set of fixing clamps is fixedly connected to the outer wall of the connecting plates, a first servo motor is fixedly installed on the front of the fixing plate, an electric push rod is fixedly installed on the outer wall of the fixing plate, a second servo motor is fixedly installed at the shaft end of the electric push rod, and a pressure block is fixedly connected to the output end of the second servo motor. Through the above components, the fixing clamps can be flexibly adjusted in spacing to adapt to the fixing requirements of cans of different specifications, while also ensuring that the cans do not shift when being sealed.

[0008] Preferably, a PLC controller is fixedly installed on the front of the fixing plate, the inner wall of the fixing block is V-shaped, the outer wall thread of the bidirectional screw passes through the inner wall of the first slider, the output end of the first servo motor is fixedly connected to one end of the bidirectional screw, and the PLC controller is electrically connected to the components to control the opening and closing of multiple components.

[0009] Preferably, a set of sliding rods is fixedly connected to the outer wall of the fixing plate. The shaft end of the sliding rod is fixedly connected to the outer wall of the connecting plate. The sliding rods can guide and support the movement of the connecting plate and the fixing block, preventing them from shifting or shaking during the movement of the first slider, ensuring the stability of the movement of the fixing block, thereby improving the stability of the tank fixing and the sealing accuracy.

[0010] Preferably, the inner wall of the fixing plate is slidably connected with a second slider, and the outer wall of the second slider is fixedly connected to the outer wall of the first slider. By setting the second slider, the stability of the first slider during the sliding process is enhanced, and the first slider is prevented from tilting or getting stuck due to uneven force. This makes the movement of the fixing block smoother and more precise, and indirectly improves the tank fixing effect and the continuity of the tank sealing operation.

[0011] Preferably, the support mechanism includes a base, a set of rotating wheels is movably inserted into the inner wall of the base, a conveyor belt is sleeved on the outer wall of the rotating wheels, the conveyor belt and the rotating wheels are connected by frictional transmission, a third servo motor is fixedly installed on the front of the base, and the output end of the third servo motor is fixedly connected to the front of one of the rotating wheels. The combination of rotating wheels, conveyor belt and third servo motor in the support mechanism constitutes a stable tank conveying system. The third servo motor provides power to the rotating wheels and drives the conveyor belt to rotate through friction, realizing automatic tank conveying, reducing manual handling and improving production efficiency.

[0012] Preferably, the bottom of each base is fixedly connected with anti-slip feet. The anti-slip feet increase the friction with the ground, effectively preventing the equipment from shifting or shaking due to vibration or force during operation, and ensuring the overall stability of the equipment.

[0013] Preferably, a guide plate is fixedly connected to the top of the base, which guides the tanks on the conveyor belt.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the first servo motor drives the bidirectional screw to rotate, which in turn drives the first slider and the connected fixed clamping block to flexibly adjust the spacing. Through the V-shaped design of the inner wall of the fixed clamping block, it can not only adapt to PET cans of different diameters, but also significantly enhance the equipment's compatibility with cans of various specifications, avoid frequent equipment changes, and effectively reduce production costs. It can also clamp and fix the can, preventing displacement or tipping during subsequent operations. In addition, the electric push rod pushes the pressure block to move down precisely, ensuring that it fits tightly with the can lid. Then, the second servo motor drives the pressure block to rotate to complete the sealing action, thereby achieving precise control of the sealing pressure and rotation angle.

[0016] 2. In this utility model, the guide support mechanism guides and supports the movement of the connecting plate and the fixed clamping block, effectively preventing them from deviating or shaking during movement, and ensuring that the fixed clamping block always runs smoothly along the preset trajectory. In addition, the third servo motor drives the rotating wheel to rotate, and drives the conveyor belt to run through friction, realizing the automatic conveying of PET cans without manual handling, reducing labor costs. At the same time, the uniform speed of the conveyor belt ensures the stable rhythm of the can entering the sealing station, further improving the overall efficiency of the production line.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a fully automatic PET can sealing device, including an integral mechanism 1, with a support mechanism 2 fixedly installed at the bottom of the integral mechanism 1; the integral mechanism 1 includes a fixing plate 101, a bidirectional screw 102 movably inserted into the inner wall of the fixing plate 101, a set of first sliders 103 slidably connected to the inner wall of the fixing plate 101, a set of connecting plates 106 fixedly connected to the bottom of the first sliders 103, a set of fixing clamps 112 fixedly connected to the outer wall of the connecting plates 106, a first servo motor 107 fixedly installed on the front of the fixing plate 101, an electric push rod 104 fixedly installed on the outer wall of the fixing plate 101, a second servo motor 111 fixedly installed at the shaft end of the electric push rod 104, and a pressure block 110 fixedly connected to the output end of the second servo motor 111. Through the above components, the fixing clamps 112 can be driven to flexibly adjust the spacing to adapt to the fixing requirements of cans of different specifications, and at the same time, it can also ensure that the cans will not shift when being sealed.

[0025] like Figure 2 As shown, a PLC controller 108 is fixedly installed on the front of the fixing plate 101. The inner wall of the fixing block 112 is V-shaped. The outer wall thread of the bidirectional screw 102 passes through the inner wall of the first slider 103. The output end of the first servo motor 107 is fixedly connected to one end of the bidirectional screw 102. The PLC controller 108 is electrically connected to the components to control the opening and closing of multiple components.

[0026] like Figure 3 As shown, a set of slide rods 109 are fixedly connected to the outer wall of the fixing plate 101. The shaft end of the slide rod 109 is fixedly connected to the outer wall of the connecting plate 106. Through the slide rods 109, the movement of the connecting plate 106 and the fixing clamp 112 can be guided and supported, preventing them from shifting or shaking during the movement with the first slider 103, ensuring the stability of the movement of the fixing clamp 112, thereby improving the stability of the tank fixing and the sealing accuracy.

[0027] like Figure 2 and Figure 3As shown, the inner wall of the fixing plate 101 is slidably connected with a second slider 105. The outer wall of the second slider 105 is fixedly connected to the outer wall of the first slider 103. By setting the second slider 105, the stability of the first slider 103 during the sliding process is enhanced, and the first slider 103 is prevented from tilting or jamming due to uneven force. This makes the movement of the fixing clamp 112 smoother and more precise, and indirectly improves the tank fixing effect and the continuity of the sealing operation.

[0028] like Figure 4 As shown, the support mechanism 2 includes a base 201. A set of rotating wheels 204 are movably inserted into the inner wall of the base 201. A conveyor belt 202 is sleeved on the outer wall of the rotating wheels 204. The conveyor belt 202 and the rotating wheels 204 are connected by frictional transmission. A third servo motor 206 is fixedly installed on the front of the base 201. The output end of the third servo motor 206 is fixedly connected to the front of one of the rotating wheels 204. The combination of the rotating wheels 204, the conveyor belt 202 and the third servo motor 206 in the support mechanism 2 constitutes a stable tank conveying system. The third servo motor 206 provides power to the rotating wheels 204 and drives the conveyor belt 202 to rotate through friction, realizing automatic tank conveying, reducing manual handling and improving production efficiency.

[0029] like Figure 4 As shown, the bottom of the base 201 is fixedly connected with anti-slip feet 205. The anti-slip feet 205 increase the friction with the ground, effectively preventing the equipment from shifting or shaking due to vibration or force during operation, and ensuring the overall stability of the equipment.

[0030] like Figure 4 As shown, a guide plate 203 is fixedly connected to the top of the base 201. The guide plate 203 guides the tank on the conveyor belt 202.

[0031] The usage and working principle of this device are as follows: First, place the PET cans on the conveyor belt 202 of the support mechanism 2. Then, start the third servo motor 206 via the control panel on the PLC controller 108. Its output drives the rotating wheel 204, which is fixedly connected to it, to rotate. Under friction, the rotating wheel 204 drives the conveyor belt 202. Simultaneously, the guide plate 203 on the top of the base 201 guides the PET cans on the conveyor belt 202, ensuring the PET cans are accurately transported to the position between the fixed clamps 112 in the overall mechanism 1. Next, the PLC controller 108 controls the first servo motor 107 to start. The output of the first servo motor 107 drives the bidirectional screw 102 to rotate. Since the outer thread of the bidirectional screw 102 penetrates the inner wall of the first slider 103, and the first slider 103 is slidably connected to the inner wall of the fixed plate 101, the rotation of the bidirectional screw 102 will drive... Two first sliders 103 slide relative to each other along the inner wall of the fixed plate 101, thereby driving the fixed clamping block 112 to move through the connecting plate 106 and adjust the spacing. The sliding rod 109 on the outer wall of the fixed plate 101 guides and supports the movement of the connecting plate 106, so that the fixed clamping block 112 moves smoothly. The V-shaped design of the inner wall of the fixed clamping block 112 is used to clamp and fix PET cans of different diameters. Then, the can lid is placed on the can body and slightly twisted. The PLC controller 108 controls the electric push rod 104 to start. The shaft end of the electric push rod 104 pushes the second servo motor 111 and the pressure block 110 to move down, so that the pressure block 110 fits tightly with the can lid of the PET can. After that, the second servo motor 111 starts, and its output end drives the pressure block 110 to rotate, completing the sealing action of the PET can. In the whole process, through the coordinated work of the above-mentioned components, the fully automatic sealing operation of the PET can is realized.

[0032] The PLC controller 108, the first servo motor 107, the second servo motor 111, the electric actuator 104, and the third servo motor 206 used in this application are all common equipment on the market and are well known to those skilled in the art. In this application, the above equipment is used in a conventional manner without any improvement to its structure and function. Regarding their settings, installation, and electrical connection methods, those skilled in the art can debug and operate them according to the corresponding product instruction manuals, so they will not be described in detail here.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
