Description

Technical Field

[0001] This utility model relates to the field of aluminum foil heat sealing technology for can lids, specifically to a can lid aluminum foil heat sealing device. Background Technology

[0002] Aluminum foil for can lids is a material used to seal can lids. It is usually made of aluminum, is thin and lightweight, and has good flexibility. It can fit tightly to the edge of the can lid to achieve a good sealing effect. The heat sealing device is a key piece of equipment used to seal the aluminum foil for can lids to the can body.

[0003] In the existing can lid aluminum foil heat sealing device, the operator places the can body and can lid aluminum foil into a fixed tray, pushes it to the bottom of the heat sealing block for alignment, and the pressure rod drives the heat sealing block to press down to heat seal it;

[0004] Existing aluminum foil heat-sealing devices for can lids are prone to deviation during the pushing process, resulting in uneven heat sealing and a large number of defective products. The stability of the can body is also poor during heat sealing, requiring the use of other stabilizing devices to fix it, which increases the workload of the workers. Therefore, we propose an aluminum foil heat-sealing device for can lids. Utility Model Content

It has strong adaptability and can be used for heat sealing aluminum foil can lids of different sizes. It has a high degree of automation, ensures a high degree of consistency in heat sealing effect, improves the overall quality stability of the product, and reduces the defect rate.

[0008] Furthermore, a microcontroller is provided on the left side of the base. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminal of the heat-sealing heating block is electrically connected to the output terminal of the microcontroller, providing electrical connections for various electrical appliances.

[0009] Furthermore, the clamping mechanism also includes a rotating column, a rotating block, and a connecting rod. The bottom wall of the base is rotatably connected to the rotating column, and the top of the rotating column is provided with a rotating block. The left end of the rotating block is rotatably connected to the bottom end of the front slider via a connecting rod through a pin, and the right end of the rotating block is rotatably connected to the bottom end of the rear slider via a connecting rod through a pin, thus ensuring the consistency of the two clamping plates.

[0010] Furthermore, the holding mechanism also includes a worm wheel and a worm. The worm wheel is sleeved on the outside of the rotating column, and the worm is rotatably connected between the front and rear inner walls of the base. The worm wheel and the worm are meshed together to ensure stable clamping.

[0011] Furthermore, the clamping mechanism also includes a right-angle motor, which is located on the front side of the base.

The outer surface of the cam is fitted with the upper surface of the pressure plate. The input end of the motor is electrically connected to the output end of the microcontroller to provide heat sealing drive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This aluminum foil heat-sealing device for can lids has the following advantages:

[0015] The rotating column rotates, causing the rotating block to move the connecting rod, which in turn pulls the slider to move centripetally within the groove. This allows the arc-shaped rubber plate to clamp the can body. During mass heat sealing, the defect rate will not increase due to different positions. Furthermore, the worm gear and worm have self-locking properties, eliminating the need for other auxiliary stabilizing and self-locking devices to fix the can body during heat sealing. This significantly reduces workflow and improves production efficiency. Attached Figure Description

A microcontroller 7 is located on the left side of the base 1, the input end of the microcontroller 7 is electrically connected to an external power source, the input end of the heat-sealing heating block 5 is electrically connected to the output end of the microcontroller 7, a pressure plate 11 is located at the upper end of the pressure rod 4, and telescopic columns 8 are respectively located on the left and right sides of the upper end of the support plate 3. The telescopic ends of the telescopic columns 8 are respectively fixedly connected to the bottom end of the pressure plate 11, and springs 10 are respectively sleeved on the outside of the telescopic columns 8, with the springs 10 located at the lower end of the pressure plate 11. Between the upper end of the support plate 3 and the upper end of the L-shaped bracket 2, a motor 8 is provided at the upper end. The output shaft of the motor 8 is fixedly connected to the front end of the cam 12. The outer surface of the cam 12 is fitted with the upper surface of the pressure plate 11. The input end of the motor 8 is electrically connected to the output end of the microcontroller 7. When the aluminum foil is placed at the filling port, the motor 8 starts to run through the control of the microcontroller 7. The output shaft drives the cam 12 to start to rotate. When the highest point of the cam 12 contacts the pressure plate 11, the pressure plate 11 drives the pressure rod 4 to press down, so that the heat sealing heating block 5 contacts the aluminum foil and heats the aluminum foil, so that the can body and the aluminum foil stick together. Then the cam 12 rotates. When the highest point leaves the pressure plate 11, the pressure plate 11 is reset under the action of the spring 10. The above operation is repeated through the control of the microcontroller 7.

[0021] Clamping mechanism 6: It includes a dovetail groove 64, a slider 65, and an arc-shaped rubber plate 66. A groove is formed in the middle of the upper surface of the base 1. Dovetail grooves 64 are formed on the left and right inner walls of the groove. Dovetail sliders are slidably connected inside the dovetail grooves 64. Slider 65 is fixedly connected between two adjacent dovetail sliders. Arc-shaped rubber plates 66 are provided at the top of the sliders 65.

When the aluminum foil of the can lid needs to be processed, the can is placed between two arc-shaped rubber plates 66. Through the control of the microcontroller 7, the right-angle motor 69 starts to run, and the output shaft drives the worm 68, which is fixedly connected at the front and rear ends, to rotate. Under the rotation of the meshing worm gear 67, the rotating column 61 also rotates, which in turn causes the rotating block 62 to start rotating, driving the connecting rod 63, which is rotatably connected by a pin, to start moving. This pulls the sliders 65 at both ends to move towards the center in the groove, clamping the can.

[0022] The working principle of the can lid aluminum foil heat sealing device provided by this utility model is as follows: When the can lid aluminum foil needs to be processed, the can is placed between two arc-shaped rubber plates 66. Under the control of the microcontroller 7, the right-angle motor 69 starts to run, and the output shaft drives the worm gear 68 fixedly connected to the front and rear ends to rotate. Under the rotation of the meshing worm wheel 67, the rotating column 61 also rotates, which in turn causes the rotating block 62 to start rotating, driving the connecting rod 63 connected by the pin shaft to start moving, pulling the sliders 65 at both ends to move inward in the groove. The can is clamped together, and the aluminum foil is placed at the filling port. Under the control of the microcontroller 7, the motor 8 starts to run, and the output shaft drives the cam 12 to start rotating. When the highest point of the cam 12 contacts the pressure plate 11, the pressure plate 11 drives the pressure rod 4 to press down, so that the heat sealing heating block 5 contacts the aluminum foil and heats the aluminum foil, so that the can and the aluminum foil stick together. Then the cam 12 rotates, and when the highest point leaves the pressure plate 11, the pressure plate 11 is reset under the action of the spring 10. The above operation is repeated under the control of the microcontroller 7.
