Description

Technical Field

[0001] This invention relates to the field of stamping and forming equipment technology, specifically to an automatic stamping and forming equipment for coating tanks. Background Technology

[0002] The automatic stamping and forming device for coated cans is a specialized piece of equipment that automates the stamping process to form metal cans with pre-coated protective or decorative coatings. It integrates functions such as automatic feeding, precision stamping, coating protection, and forming inspection, and is widely used in food packaging, beverage packaging, chemical containers, and other fields. It can efficiently produce metal cans that meet the requirements of coating integrity, and is therefore widely used in industrial production. However, some problems still occur in the actual use of existing coated can stamping and forming devices. For example, patent application number CN202123365938.8 discloses an automatic can stamping and forming device, including a frame, a mold slidably connected to the frame, a slider welded to the mold, a connecting rod hinged to the slider, a support plate hinged to the connecting rod, a cylinder fixedly mounted on the support plate, a cylinder rod slidably connected to the support plate, a connecting sleeve slidably connected to the outside of the cylinder rod, the connecting sleeve being welded to the frame, and a hanging rod welded to the frame. This device facilitates the separation of the product from the mold. Existing coating can stamping and forming devices generally have a simple structure and often require multiple steps to apply the coating to the sides of the can, resulting in high complexity and potentially poor subsequent can processing effects, thus affecting the device's performance.

[0003] To address the aforementioned problems, an automatic stamping and forming device for coating tanks is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic stamping and forming device for coating cans. By using this device, the problem of existing coating can stamping and forming devices having a simple structure, often requiring multiple steps to apply coating to the sides of the can, which is highly complex and can easily lead to poor subsequent can processing results, thus affecting the effectiveness of the device.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic stamping and forming device for coating cans, comprising a guide frame and a support frame slidably connected inside the guide frame. A fixed frame is fixedly connected to the top of the guide frame, and a telescopic cylinder is fixedly connected to the top of the fixed frame. A sliding frame is fixedly connected to the output end of the telescopic cylinder, and a motor is fixedly connected to one side of the sliding frame. The output end of the motor extends into the interior of the sliding frame and is fixedly connected to a bevel gear. A telescopic cylinder is fixedly connected inside the guide frame. The guide frame is provided with a conveying mechanism, which conveys the can body. The conveying mechanism includes a motor fixedly connected to one end of the guide frame, and a connecting groove is provided on one side of the support frame.

[0006] Preferably, the sliding frame is slidably connected inside the fixed frame, and two sets of motor one and bevel gear one are provided. One side of bevel gear one is meshed with bevel gear two, and bevel gear two is rotatably connected inside the sliding frame.

[0007] The above-mentioned structural design, through the "sliding connection between the sliding frame and the fixed frame," ensures that the sliding frame can stably rise and fall along the fixed frame under the drive of the telescopic cylinder, avoiding deviation during the rising and falling process. The symmetrical arrangement of "two sets of motors and bevel gears" and the meshing bevel gear can synchronously drive the transmission structures on both sides, ensuring the symmetry of coating conveying and stamping, preventing coating adhesion deviation caused by uneven force on one side, and laying a structural foundation for the precise stamping of the coating at both ends of the tank.

[0008] Preferably, a take-up roller is fixedly connected to the top of the bevel gear two, an outlet groove is provided on the inner side of the sliding frame, and multiple sets of outlet grooves are provided. A transmission screw is fixedly connected to the output end of the motor three, and the transmission screw is threadedly connected to the support frame.

[0009] The above-mentioned structural design, with "bevel gear two fixedly connected to take-up roller one," converts the rotational power of motor one into the take-up and unwinding action of take-up roller one, realizing automatic coating film conveying; "multiple sets of guide grooves" can guide and limit the coating film, preventing wrinkles or deviations during conveying and ensuring that the coating film adheres to the can body along the preset path; "motor three is threadedly connected to the support frame through a transmission screw," which can convert the rotational motion of motor three into the linear sliding of the support frame, realizing precise displacement of the can body within the guide frame, facilitating the conveying of the can body to different stamping stations, reducing manual handling steps, and improving the degree of automation.

[0010] Preferably, the support frame has slots on both the left and right sides that match the outlet slots, and multiple sets of telescopic cylinders are provided. The output end of the telescopic cylinder is fixedly connected to a guide rod, and one end of the guide rod is fixedly connected to a sliding plate.

[0011] The above-mentioned structural design, with its "grooves on both sides of the support frame matching the outlet groove," forms a continuous coating conveying channel with the outlet groove of the sliding frame. This ensures that the coating extends smoothly from the outlet groove to the surface of the tank on the support frame, preventing the coating from getting stuck at the junction. The "multiple sets of telescopic cylinders II" synchronously drive the guide rod, providing a stable and uniform driving force to the sliding plate and preventing it from tilting during movement. The "guide rod connecting the telescopic cylinders II and the sliding plate" precisely controls the direction of movement of the sliding plate, ensuring that the sliding plate drives the subsequent stamping components to accurately act on the tank, thus improving stamping accuracy.

[0012] Preferably, an arc-shaped plate is fixedly connected to the bottom end of the sliding plate, and a cutting tool is fixedly connected to the bottom of the arc-shaped plate. The cutting tool is arc-shaped, and a placement frame is fixedly connected to one side of the guide frame. Two sets of placement frames are provided.

[0013] The above-mentioned structural design features an "arc plate that fits the shape of the tank," allowing it to fit tightly against the tank surface during stamping. This ensures that the coating adheres evenly to the outside of the tank, preventing localized bubbles or areas of poor adhesion. The "arc-shaped cutting tool" can precisely cut off excess coating along the arc of the tank after stamping, reducing coating waste while ensuring the cleanliness of the tank edges. Two sets of placement racks are symmetrically distributed on both sides of the guide frame, allowing for the installation of coating supply components such as the winding roller, enabling simultaneous supply of coating to both sides of the tank and improving the processing efficiency of the coating on the outside of the tank.

[0014] Preferably, a second motor is fixedly connected to one side of the placement frame, a second take-up roller is fixedly connected to the output end of the second motor, a sliding block is slidably connected to the top of the guide frame, a spring rod is fixedly connected to the bottom of the sliding block, and one end of the spring rod is fixedly connected to the inside of the guide frame.

[0015] The above-mentioned structural design, with "motor two driving take-up roller two", enables automatic unwinding of the coating film. It precisely controls the conveying speed and length of the coating film according to the stamping rhythm, avoiding excessively fast conveying that leads to accumulation or excessively slow conveying that leads to insufficient supply. "The sliding block and spring rod work together to provide elastic tension to the coating film during conveying. The position of the sliding block is adjusted by the extension and retraction of the spring rod to ensure that the coating film always maintains appropriate tension, preventing the coating film from loosening and affecting the bonding effect, while also avoiding excessive tension that could damage the coating film.

[0016] Preferably, an electromagnet is fixedly connected inside the guide frame, the electromagnet is electrically connected to the second motor, a first transmission roller is rotatably connected inside the guide frame, the first transmission roller is rotatably connected inside the connecting groove, and a second transmission roller is fixedly connected to the top of the guide frame.

[0017] The above-described structure, with its "electromagnet and motor 2 electrically connected," allows the start and stop of motor 2 to be controlled by the on / off state of the electromagnet, thus linking the coating conveying and stamping actions. When the stamping components are ready, the electromagnet is energized to start motor 2 to deliver the coating, and the electromagnet is de-energized after stamping to stop the delivery, enhancing the automation and coordination of the device. The "drive roller 1 located in the connecting groove" assists in the smooth conveying of the coating within the groove, reducing frictional damage between the coating and the inner wall of the groove. The "drive roller 2 at the top of the guide frame" provides secondary guidance for the coating, ensuring that the coating covers the surface of the tank at the correct angle, further improving the accuracy of coating adhesion.

[0018] Preferably, the transmission rollers are provided in two sets, and the internal support frame is fixedly connected to the telescopic cylinders. The telescopic cylinders are provided in two sets, and the output end of the telescopic cylinders is fixedly connected to the mounting plate.

[0019] With the above-mentioned structural design, the two sets of drive rollers are symmetrically distributed, which can guide and limit the coating from both sides to prevent the coating from shifting when it is delivered to the top of the tank, ensuring that the coating coverage is uniform. The two sets of telescopic cylinders drive the mounting plate synchronously, which can provide symmetrical and stable clamping force for the clamping plate, preventing the tank from shifting due to force on one side during the stamping process. At the same time, it ensures that the stamping pressure of the clamping plate on the coating at both ends of the tank is consistent, thus improving the stamping quality.

[0020] Preferably, a clamping plate is fixedly connected to the top of the mounting plate, and a second cutting tool is fixedly connected to the inner side of the clamping plate. The second cutting tool is annular.

[0021] The above-mentioned structural design, with "the clamping plate matching the shape of the tank end", allows it to closely fit the tank end under the drive of the telescopic cylinder three, firmly pressing the coating film onto the tank surface and achieving precise stamping of the coating film at the tank end; "ring cutting tool two" can precisely cut off excess coating film along the edge of the tank end after stamping, making the edge of the coating film at the tank end neat, eliminating the need for subsequent secondary trimming, reducing processing steps, and at the same time, the ring structure can ensure that the cutting trajectory is completely matched with the tank end, improving cutting accuracy.

[0022] Preferably, a support frame is also fixedly connected inside the bearing frame, and two sets of support frames are provided, which are matched with the arc-shaped plate.

[0023] With the above-mentioned structural design, "two sets of support frames" are symmetrically fixed inside the bearing frame, which can provide stable support for the tank from below, preventing the tank from sinking or shifting due to force during the stamping of the arc plate; "the support frames are matched with the arc plate", which can form an upper and lower clamping and positioning of the tank with the arc plate when the arc plate is pressed down for stamping, ensuring that the tank maintains a stable posture during the stamping process, while avoiding excessive pressure from the arc plate that could cause deformation of the tank, thus ensuring the integrity of the tank's shape after stamping.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This application, through the arrangement of motor one, bearing frame, transmission screw and bevel gear one, enables workers to easily stamp the film on the outside of the can, improves the subsequent use effect, and solves the problem that the existing coating can stamping and forming devices generally have a simple structure, often requiring multiple steps to apply the coating to the sides of the can, which is highly complicated and easily leads to poor subsequent can processing effect, thus affecting the use effect of the device.

[0025] 2. By setting up transmission roller one, transmission roller two and the guide groove, this application can effectively prevent the can from shifting during the stamping process, improve the working efficiency of the device, and solve the problem that most existing coating can stamping and forming devices lack an effective correction structure, making it inconvenient for workers to make adjustments when the coating deviates.

The output end of the motor 113 extends into the interior of the sliding frame 112 and is fixedly connected to a bevel gear 114. A telescopic cylinder 12 is fixedly connected inside the guide frame 1. The guide frame 1 is provided with a conveying mechanism, which conveys the can body. The conveying mechanism includes a motor 21 fixedly connected to one end of the guide frame 1. A connecting groove 22 is provided on one side of the support frame 2.

[0031] The present invention will be further described below with reference to embodiments.

[0032] Example 1: To address the problem that existing coating can stamping and forming equipment generally has a simple structure and often requires multiple steps to apply the coating to the can body, resulting in high complexity and potentially poor subsequent can processing quality, thus affecting the effectiveness of the equipment, this embodiment discloses the following technical solution, specifically as follows: Figures 1-10As shown, the sliding frame 112 is slidably connected inside the fixed frame 11. Two sets of motor 113 and bevel gear 114 are provided. One side of bevel gear 114 is meshed with bevel gear 115, which is rotatably connected inside the sliding frame 112. A take-up roller 116 is fixedly connected to the top of bevel gear 115. An outlet groove 117 is provided on the inner side of the sliding frame 112, and multiple sets of outlet grooves 117 are provided. A transmission screw 211 is fixedly connected to the output end of motor 21, and the transmission screw 211 is threadedly connected to the support frame 2. Grooves matching the outlet grooves 117 are provided on both the left and right sides of the support frame 2. Multiple sets of telescopic cylinders 12 are provided, and a guide rod 121 is fixedly connected to the output end of telescopic cylinder 12. A sliding plate 122 is fixedly connected to one end of the guide rod 121. An arc-shaped plate 123 is fixedly connected to the bottom end of the sliding plate 122. A cutting tool 124 is fixedly connected to the bottom of the arc-shaped plate 123. The cutting tool 124 is arc-shaped. A placement frame 13 is fixedly connected to one side of the guide frame 1. Two sets of placement frames 13 are provided. A second motor 131 is fixedly connected to one side of the placement frame 13. A second take-up roller 132 is fixedly connected to the output end of the second motor 131. A sliding block 133 is slidably connected to the top of the guide frame 1. A spring rod 134 is fixedly connected to the bottom of the sliding block 133. One end of the spring rod 134 is fixedly connected to the inside of the guide frame 1. An electromagnet 135 is also fixedly connected to the inside of the guide frame 1. The electromagnet 135 is electrically connected to the second motor 131. The support frame 2 has two sets of telescopic cylinders 23 fixedly connected inside. The output end of each cylinder is fixedly connected to a mounting plate 231. A clamping plate 232 is fixedly connected to the top of the mounting plate 231, and a cutting tool 233 (ring-shaped) is fixedly connected to the inner side of the clamping plate 232. The support frame 234 also has two sets fixedly connected inside, matching the arc-shaped plate 123. During use, the tank to be processed can be placed on top of the support frame 2. After installation, the motor 21 located at one end of the guide frame 1 can be started. The motor 21 drives the transmission screw 211 to rotate, thus causing the support frame 2 to rotate inside the guide frame 1. When the support frame 2 moves to the bottom of the fixed frame 11, the telescopic cylinder 111 is activated. The telescopic cylinder 111 moves the sliding frame 112, placing it outside the support frame 2. This activates the motor 113 located on one side of the sliding frame 112. The motor 113 drives the bevel gear 114 to rotate, which in turn drives the bevel gear 115. The bevel gear 115 drives the take-up roller 116 to rotate, causing the film outside the take-up roller 116 to move through the guide groove 117 to both ends of the tank. The telescopic cylinder 23 inside the support frame 2 can then be activated. The telescopic cylinder 23 moves the mounting plate 231, which in turn moves the clamping plate 232. The clamping plate 232 can perform a pressing operation on the film. After the operation is completed...Reverse activation of telescopic cylinder 111 raises sliding frame 112. When stamping is required on the outside of the tank, motor 21 moves support frame 2 below sliding plate 122. This activates telescopic cylinder 12 inside guide frame 1 and motor 131 on one side of placement frame 13. Motor 131 rotates take-up roller 132, causing the film on the outside of take-up roller 132 to cover the outside of the tank. Telescopic cylinder 12 then moves guide rod 121, causing sliding plate 122 to move. Sliding plate 122 moves arc plate 123, which stamps the tank and, with cutting tool 124, cuts the film for later use. This allows workers to easily stamp the film on the outside of the tank, improving subsequent performance.

[0033] Example 2: To address this issue, this embodiment discloses the following technical solution, specifically as follows: Figure 6 and Figure 7 As shown, a transmission roller 221 is rotatably connected inside the guide frame 1. The transmission roller 221 is rotatably connected inside the connecting groove 22. A transmission roller 222 is fixedly connected to the top of the guide frame 1. There are two sets of transmission rollers 222. When the motor 21 drives the support frame 2 to move to the sliding plate 122, the coating film can be transmitted to the tank through the connecting groove 22. The tension of the coating film is improved by the transmission roller 221 inside the connecting groove 22. The coating film can be evenly distributed on the outside of the tank by the two sets of transmission rollers 222. The arc-shaped arrangement of the arc plate 123 and the support frame 234 allows the tank to be stamped more evenly, preventing the tank from shaking inside the support frame 2. The clamping plate 232 improves the stability of the tank and effectively prevents the tank from shifting during the stamping process, thus improving the working efficiency of the device.
