[0003] After a large amount of retrieval, it is found that the prior art publication CN113600707B discloses a stretching and trimming device for beverage can production and processing, including: a mounting base plate; a resisting column assembly, which is fixedly installed at one end of the mounting base plate; a hot stretching assembly, the hot stretching assembly includes a base, a mounting block, and a plurality of hot stretching rings, the base is fixedly connected to the middle of the mounting base plate, the mounting block is fixedly inserted on the base through an inserting assembly, a plurality of the hot stretching rings are equidistantly installed inside the groove, and the inner diameters of the plurality of hot stretching rings are different; a fixing assembly, which is installed between the resisting column assembly and the hot stretching assembly for fixing the aluminum cap piece; a can discharging assembly, which is fixedly installed on one side of the mounting base plate away from the resisting column assembly; a circumferential cutting assembly, which is fixedly installed between the hot stretching assembly and the can discharging assembly.

[0004] Therefore, based on the above retrieval and in combination with the existing ones, this patent uses a circumferential cutting method to trim the beverage can. However, in actual use, the blade needs to surround the edge of the can body for one week to complete the cutting, resulting in a slow trimming speed of the device, seriously affecting the continuous processing efficiency of the device, and the blade may also cause uneven trimming due to vibration or deviation during rotation, with low cutting accuracy and reduced product quality. Summary of the Invention

[0005] The purpose of the present invention is to provide a stretching and trimming device for beverage can production and processing to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A stretching and trimming device for beverage can production and processing, including a support frame, a base is fixedly connected inside the support frame, a top cover is fixedly connected to the top of the base, a plurality of shaping rings for stretching the can body are clamped between the base and the top cover, a push rod for assisting stretching is slidably connected to one end of the base, and a repair box is fixedly connected to the other end of the base. The can body is pushed through the shaping rings in sequence by the push rod, thereby achieving the effect of stretching and forming the can body; A trimming structure for trimming the can body is fixedly installed inside the repair box, and a conveying structure for conveying the processing material is fixedly installed on the top surface of the support frame.

[0007] As a further solution of the present invention, the trimming structure includes electric push rods. There are two groups of electric push rods, and both are fixedly installed inside the repair box. At one end of the two groups of electric push rods corresponding to each other, a stamping ring is fixedly installed. Inside the inner walls of the two stamping rings, a cutter for trimming and cutting is fixedly installed.

[0008] As a further solution of the present invention, a vertical frame is fixedly installed on the inner wall of the repair box. Inside the vertical frame, a repair ring for leveling the cut of the tank body is fixedly installed. Inside the push rod, an inner push rod for pushing the tank body for repair is fixedly installed.

[0009] As a further solution of the present invention, in order to enhance the stability of the stretched tank body structure, a model block for shaping the bottom of the tank body is slidably installed on the inner wall of the repair box away from the base. At the output end of the inner push rod, a pushing block for assisting in shaping is fixedly installed, and a groove with the same shape as the model block is opened inside the pushing block.

[0010] As a further solution of the present invention, a waste pipe is fixedly installed on the lower surface of the repair box, and a waste box for collecting waste is fixedly installed below the waste pipe.

[0011] As a further solution of the present invention, an electric rod for providing power is fixedly installed at one end of the push rod away from the base. An extrusion ring for assisting in fixing the processing material is slidably sleeved on the outer wall of the push rod.

[0012] As a further solution of the present invention, an injection pipe for injecting processing material is fixedly installed on the top surface of the top cover.

A turntable for ensuring the precise falling of the processing material into the injection pipe is fixedly sleeved on the outer wall of the rotating rod, and a card slot is opened inside the turntable.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When the present invention is in use, after the pushing rod is used to push the can body through the stamping ring, the inductor in the electric push rod senses the sensor in the pushing rod and quickly drives the electric push rod to move the stamping ring, so that the cutter directly cuts into the preset cutting groove on the outer wall of the pushing rod to cut the edge of the can body. This method greatly improves the trimming speed of the device. There is no need for the blade to cut around for a long time, and the trimming operation can be quickly completed, improving the continuous processing efficiency of the device. Moreover, the cutter is not in a rotating state, avoiding the problem of uneven trimming caused by rotational vibration or deviation, ensuring the cutting accuracy of the device, thus effectively improving the product quality and providing a strong guarantee for the high-quality production of aluminum cans; 2. When the present invention is in use, the repair ring and the inner push rod can be used to repair the flatness of the can mouth of the trimmed aluminum can. One end of the pushing rod moves into the repair ring to provide stable support for repairing the can mouth. In cooperation with the inner push rod to push the can body through the repair ring, under the combined extrusion of the two, the can mouth is restored to flatness, effectively repairing the problem of uneven can mouth that may occur after trimming, improving the regularity of the can body edge, ensuring the integrity and usability of the whole can body, and the inner push rod can also be used to separate the can body from the pushing rod, without manual intervention, quickly entering the next round of can body processing, improving the production efficiency of the device, and ensuring the smoothness and continuity of the whole production process; 3. When the present invention is in use, through the coordinated work of the roller conveyor belt, the electric rod, the electric push rod and the inner push rod, the whole process of automatic operation from processing material transportation to aluminum can forming, trimming, repairing and output is realized, greatly improving the production efficiency of the device, ensuring the production quality of aluminum cans, reducing manual intervention, ensuring the continuity and stability of the device production process, and meeting the strict requirements of large-scale production for efficiency and quality.

Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figures 1 to 2 , a stretching and trimming device for the production and processing of aluminum cans, including a support frame 1. A base 2 is fixedly connected inside the support frame 1. The top of the base 2 is fixedly connected with a top cover 3 through bolts. A plurality of shaping rings 4 for stretching the can body are clamped between the base 2 and the top cover 3. One end of the base 2 is slidably connected with a push rod 5 for assisting in stretching, and the other end of the base 2 is fixedly connected with a repair box 6. The push rod 5 is used to push the can body through the shaping rings 4 in sequence, thereby achieving the effect of stretching and forming the can body; A trimming structure for trimming the can body is fixedly installed inside the repair box 6, and a conveying structure for conveying the processing material is fixedly installed on the top surface of the support frame 1; Specifically, the support frame 1 is the support main body of the entire device, made of high-strength steel, which can withstand the vibration and load during the operation of the device, play a role in stably carrying each component, and ensure the stability and rigidity of the device during operation. The base 2 provides a basic platform for subsequent processing operations. An forming cavity for stretching the can body is provided between the base 2 and the top cover 3. The inner diameters of a plurality of shaping rings 4 gradually decrease from left to right (specifically, please refer to Figure 5 ). During the process of the push rod 5 pushing the can body through the shaping rings 4 in sequence, the can body is gradually stretched to meet the expected shape and size requirements, thereby realizing the stretching and forming of the can body. The shaping ring 4 is made of high-hardness and wear-resistant materials to ensure that it does not deform after long-term use, and its inner surface is polished to reduce the frictional resistance; More specifically, a fixing frame 7 is fixedly connected to one side of the base 2 close to the push rod 5. An outer wall of the fixing frame 7 is fixedly sleeved with a connecting frame 8 for assisting in fixing the base 2, and the connecting frame 8 is fixedly connected to the support frame 1. The fixing frame 7 effectively reduces the impact on the base 2 generated by the reciprocating movement of the push rod 5. The connecting frame 8 makes the structure of the whole device more firm and ensures the stability when all components work together; Please refer to Figures 2 to 4 , the trimming structure includes electric push rods 901. There are two groups of electric push rods 901, and both are fixedly installed inside the repair box 6. Corresponding ends of the two groups of electric push rods 901 are fixedly installed with stamping rings 902 through connecting parts, and an inner wall of each of the two stamping rings 902 is fixedly installed with a cutting tool 903 for trimming and cutting; Specifically, a cutting groove for assisting in trimming is formed on an outer wall of the push rod 5. Driven by the electric push rod 901, the cutting tool 903 can cut into the cutting groove on the outer wall of the push rod 5 to cut the edge of the can body, achieving the purpose of trimming, ensuring the neatness of the edge of the can body. One end of the push rod 5 is provided with a chamfer to facilitate shaping the bottom of the aluminum can, and there is a certain distance between the cutting groove on the outer wall of the push rod 5 and the end of the push rod 5 provided with the chamfer. The cutting tool 903 is made of cemented carbide material, with strong wear resistance, ensuring a smooth cutting edge; More specifically, a sensor is fixedly installed inside the push rod 5, and the position of the sensor corresponds to the cutting groove. An inductor is fixedly installed inside the electric push rod 901. When the push rod 5 pushes the can body through the stamping ring 902, when the inductor senses the sensor, it drives the electric push rod 901 to push the stamping ring 902 to move, so that the cutting tool 903 cuts into the cutting groove, and then cuts the edge of the can body, achieving the purpose of trimming. Cooperating with the sensor, it can provide a positioning basis for the trimming operation; More specifically, the electric push rod 901 pushes the stamping ring 902 to move, so that the cutting tool 903 cuts the edge of the can body. This trimming method abandons the mode of slow circumferential cutting of the circumferential cutting blade, improves the trimming speed, and the cutting tool 903 is not in a rotating state, avoiding the problem of uneven trimming caused by rotational vibration or deviation. The cutting tool 903 can always remain stable during the cutting process, ensuring a neat and smooth cutting edge, greatly improving the cutting accuracy, ensuring product quality. At the same time, due to the efficient cutting of the cutting tool 903, the device can quickly complete the trimming operation, improving the continuous processing efficiency, and can well meet the production requirements of large scale and high efficiency, bringing higher economic benefits and market competitiveness to the enterprise; A vertical frame 904 is fixedly installed on an inner wall of the repair box 6, and a repair ring 905 for leveling the cut of the can body is fixedly installed inside the vertical frame 904. An inner push rod 906 for pushing the can body for repair is fixedly installed inside the push rod 5; Specifically, the repair ring 905 has the same inner diameter as the plastic ring 4 closest to the repair box 6, which can ensure that the size of the repaired tank body is consistent. The push rod 5 stops moving during stamping and cutting. At this time, one end of the push rod 5 moves into the repair ring 905 to provide stable support for repairing the tank mouth. In cooperation with the inner push rod 906, the tank body is pushed through the repair ring 905. Under the combined extrusion of the repair ring 905 and the push rod 5, the tank mouth is restored to be flat, ensuring the regularity and quality of the edge of the tank body, and improving the overall integrity and usability of the tank body; More specifically, the inner push rod 906 not only plays the role of pushing the tank body for repair, but also can cause the tank body to separate from the push rod 5, enabling the device to quickly enter the next round of tank body processing without manual intervention, greatly improving production efficiency and ensuring the continuity and smoothness of the entire production process; To enhance the stability of the stretched tank body structure, a model block 907 for shaping the bottom of the tank body is slidably installed on the inner wall of the side of the repair box 6 away from the base 2. The output end of the inner push rod 906 is fixedly installed with a pushing block 908 for assisting in shaping, and a groove with the same shape as the model block 907 is opened inside the pushing block 908 to ensure shaping accuracy; Specifically, the inner push rod 906 drives the pushing block 908 to push one end of the tank body to fit with the model block 907, so as to achieve the purpose of shaping the bottom of the tank body, making the bottom of the tank body form a specific shape, enhancing the stability of the stretched tank body structure. During the process of pushing the tank body to fit with the model block 907 for shaping, the groove of the pushing block 908 can accurately position and stably push the tank body, ensuring the accuracy and consistency of the shaping process, effectively avoiding shaping defects caused by positioning deviation, and further improving the accuracy and quality of the bottom shaping of the tank body; More specifically, an auxiliary rod 909 for assisting the model block 907 to move smoothly is slidably inserted into the model block 907. The auxiliary rod 909 can assist the model block 907 to move smoothly, effectively reducing the shaking and deviation of the model block 907 during movement, ensuring the stability and accuracy of the shaping process. A return spring 910 for pushing the model block 907 to reset is fixedly installed on one side of the model block 907, and the elastic force of the return spring 910 can quickly and smoothly push the tank body to separate from the model block 907, making full preparations for the next shaping operation and improving the production efficiency of the device; An output pipe 911 for guiding the output of the aluminum can is fixedly installed on the bottom surface of the repair box 6, and a conveyor belt 915 for transporting the aluminum can is installed below the output pipe 911. The output pipe 911 guides the processed aluminum can to the conveyor belt 915, which can realize the rapid and continuous transportation of the aluminum can, realize the automatic transportation of the finished product, greatly improve the coherence of the production process, reduce the manual handling link, reduce the labor intensity, and improve the production efficiency (the conveyor belt 915 is a prior art and will not be elaborated here); A spring piece 912 for assisting the cutting waste to break away from the push rod 5 is fixedly installed on the inner wall of the repair box 6. When the push rod 5 completes stretching and retracts, the spring piece 912 pushes the waste away from the push rod 5 through elastic force, preventing the waste from sticking or jamming, ensuring the smooth demolding of the waste, and improving production efficiency; A waste pipe 913 is fixedly installed on the lower surface of the repair box 6, and a waste box 914 for collecting waste is fixedly installed below the waste pipe 913. The waste smoothly flows into the lower waste box 914 under the action of gravity. The waste box 914 adopts a large-capacity design, which is convenient for regular cleaning and recycling of waste, keeps the working environment clean, and at the same time realizes the centralized treatment and resource recycling of waste.

[0020] Example 2: Please refer to Figures 4 to 5 , a stretching and trimming device for can production and processing. The difference from Example 1 is that an electric rod 10 for providing power is fixedly installed at one end of the push rod 5 far from the base 2 through a flange, and the electric rod 10 is fixedly connected to the fixing frame 7. An extrusion ring 11 for assisting in fixing the processing material is slidably sleeved on the outer wall of the push rod 5; An injection pipe 12 for injecting the processing material is fixedly installed on the top surface of the top cover 3. Clamping plates 13 for fixing the shaping ring 4 are fixedly installed on the inner walls of the base 2 and the top cover 3, and the shaping ring 4 is located within the clamping plates 13; Specifically, the push rod 5 and the electric rod 10 are fixedly connected through a flange, so as to facilitate the disassembly and replacement of the push rod 5 with different cutting groove positions according to the required size of the can, further enhancing the flexibility and applicability of the device; Specifically, the outer diameter of the extrusion ring 11 is equal to the inner diameters of the base 2 and the top cover 3. The processing material falls into the base 2 from the injection pipe 12, and the electric rod 10 drives the extrusion ring 11 to cooperate with the base 2 and the top cover 3 to extrude the processing material, thereby ensuring the stability of the processing material. By removing the bolts on the inner wall of the top cover 3, it is convenient to replace the shaping ring 4 and extend the service life of the device; More specifically, a restoring spring 14 for pushing the extrusion ring 11 to reset is fixedly installed on the outer wall of the extrusion ring 11, and one end of the restoring spring 14 is in contact with the outer walls of the base 2 and the top cover 3.

[0021] Example 3: Please refer to Figures 6 to 7 , a stretching and trimming device for can production and processing. The difference from Example 1 is that the conveying structure includes a roller conveyor belt 151. The roller conveyor belt 151 is fixedly installed on the top of the support frame 1, a baffle 152 is fixedly installed on the top of the roller conveyor belt 151, and a partition plate 153 for diverting the processing material is fixedly installed at the center of the baffle 152; Specifically, the roller conveyor belt 151 is provided with multiple groups of transmission rollers, and except for two groups of transmission rollers, the outer walls of the remaining transmission rollers are all fixedly sleeved with rollers, and there is a gap between each two groups of rollers, so that the gaps between the two groups of transmission rollers without rollers and the adjacent rollers are enlarged, so as to facilitate the processing material to fall into the injection pipe 12, and realize the automatic transportation and positioning of the processing material (the roller conveyor belt 151 is a prior art, and the specific structure is not described in detail here); The conveying structure also includes a rotating rod 154, and a rotating disc 155 is fixedly sleeved on the outer wall of the rotating rod 154 to ensure that the processed material falls accurately into the injection pipe 12, and a card slot is opened inside the rotating disc 155; Specifically, one end of the rotating rod 154 is fixedly connected to the connecting frame 8 through a bearing, and the other end of the rotating rod 154 is penetrated by a turntable 155 on which a motor 156 is fixedly installed. The motor 156 drives the rotating rod 154 and the turntable 155 to rotate. The slot on the turntable 155 can ensure that the processed material falls accurately into the injection pipe 12, thereby improving the accuracy of the processed material delivery and further improving the processing quality and production efficiency.

[0022] The working principle of the present invention is: First, the processing material is transported by the roller conveyor belt 151, and the processing material falls into the injection pipe 12 through the gap between the rollers. At the same time, the motor 156 drives the rotating rod 154 to drive the turntable 155 to rotate. The groove on the turntable 155 receives the falling processing material, and the processing material rotates with the turntable 155, so that the processing material falls accurately from the injection pipe 12 into the base 2; Then, the electric rod 10 drives the extrusion ring 11 to cooperate with the base 2 and the top cover 3 to extrude and fix the processed material, and then the electric rod 10 continues to move, thereby driving the push rod 5 to push the can body to pass through the shaping ring 4 in sequence to achieve stretching and forming. When the push rod 5 pushes the can body to pass through the punching ring 902, the sensor in the electric push rod 901 senses the sensor in the push rod 5, drives the electric push rod 901 to push the punching ring 902, and makes the cutter 903 cut into the cutting groove to trim the can body, and at the same time, the electric rod 10 stops moving; Finally, the inner push rod 906 pushes the can body through the repair ring 905 to restore the can mouth to a flat state, and also causes the can body to separate from the push rod 5. At the same time, the inner push rod 906 drives the push block 908 to push the can body and the model block 907 to fit together to shape the bottom of the can body. The reset spring 910 pushes the can body and the model block 907 to separate. The formed can falls through the output pipe 911 and falls on the conveyor belt 915 for transportation out. The cut waste is pushed away from the push rod 5 by the spring sheet 912 when the push rod 5 retracts and resets, and the waste falls into the waste box 914 through the waste pipe 913.
