Description

Technical Field

[0001] This utility model relates to the field of can sealing technology, and in particular to a can sealing machine. Background Technology

[0002] With the rapid development of the canning industry, canned products have quickly entered ordinary households due to their flexibility and ease of use. China has become a major producer of canned products. During the processing of cans, the bottom of the can needs to be sealed to ensure the airtightness and performance of the can.

[0003] A search revealed a publication (announcement) number: CN218964441U, which discloses a bottom-sealing machine for cans, relating to the technical field of bottom-sealing equipment. The technical solution includes a workbench with a straight groove on its top. Multiple springs are fixedly connected to the inner walls of both sides of the straight groove. A limiting plate is fixedly connected to the ends of the springs away from the inner walls of the straight groove. Multiple support blocks are fixedly installed on the outer walls of the workbench, and a first cylinder is installed on the outer wall of each support block. A clamping plate is fixedly connected to the output shafts of two first cylinders. An anti-slip pad is installed on the outer wall of the clamping plate away from the first cylinder. In this invention, by embedding the can into the straight groove, the multiple springs generate elastic force to drive the two limiting plates to clamp the can. Because the springs have elastic force, the can is not damaged during clamping. Simultaneously, the clamping plate is driven by the first cylinders to clamp and fix multiple cans. The anti-slip pad prevents the can from shifting or sliding during bottom sealing and does not damage the can surface.

[0004] While the above solution can prevent the tank from shifting or sliding during the bottom sealing process and will not damage the tank surface, the sealing process is relatively slow, the number of tanks that can be sealed at one time is limited, and the restriction effect on the tank is poor, resulting in certain errors in the bottom sealing process. Utility Model Content

[0005] The main purpose of this utility model is to provide a bottom sealing machine for can products. By setting a bottom sealing unit, it solves the problems of slow speed and limited number of bottoms sealed at one time. By setting a limiting unit, it solves the problem of poor restriction effect on the can body, which leads to certain errors in the bottom sealing.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bottom sealing machine for canned products includes a main body and a plurality of support columns fixedly connected to the bottom end of the main body, a bottom sealing unit disposed inside the main body, and a limiting unit disposed at the top of the bottom sealing unit;

[0008] The bottom sealing unit includes a movable groove inside the main body, multiple placement grooves connected to the bottom of the movable groove, a moving component inside the movable groove, and a feeding component inside the placement groove.

[0009] The limiting unit includes a fixed frame fixedly connected to the top of the main body, a cylinder fixedly connected to the top of the fixed frame, a snap-fit ​​component disposed at the bottom of the cylinder, and a limiting component disposed at the bottom of the snap-fit ​​component.

[0010] Preferably, the movable component in the bottom sealing unit includes two rotating shafts disposed inside the movable groove, a linkage column fixedly connected to the outside of the rotating shafts, a conveyor belt disposed outside the linkage column, a plurality of fixed columns fixedly connected to the outside of the conveyor belt, and a suction cup fixedly connected to one end of the fixed column.

[0011] Preferably, the movable component in the bottom sealing unit further includes a rotating motor disposed on one side of the front of the main body, and the output end of the rotating motor is fixedly connected to one of the rotating shafts.

[0012] Preferably, the feeding assembly in the bottom sealing unit includes an electric telescopic rod disposed at the bottom of the placement groove, a limiting layer fixedly connected to the middle of the placement groove, limiting blocks disposed on both sides of the placement groove and at the top of the limiting layer, a first elastic column fixedly connected to one end of the limiting block, and a first spring disposed on the surface of the first elastic column.

[0013] Preferably, the locking assembly in the limiting unit includes a telescopic column fixedly connected to the bottom of the cylinder, a horizontal plate fixedly connected to the bottom of the telescopic column, a locking plate disposed on the side of the horizontal plate, a sliding groove opened on one side of the top of the locking plate, and a rectangular groove connected to the bottom of the sliding groove.

[0014] Preferably, the width of the sliding groove in the limiting unit locking assembly is smaller than the width of the rectangular groove, and the telescopic column is locked with the sliding groove, and the horizontal plate is locked with the rectangular groove.

[0015] Preferably, the limiting component in the limiting unit includes a plurality of limiting seats fixedly connected to the bottom end of the snap-fit ​​plate, a limiting groove opened inside the limiting seat, a second elastic post disposed on both sides inside the limiting groove, a second spring disposed on the surface of the second elastic post, and an arc-shaped plate fixedly connected to one side of the second elastic post.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, by setting up a bottom sealing unit, multiple bottom sealing raw materials are placed in multiple placement slots. Activating multiple electric telescopic rods can drive the bottom sealing raw materials to rise, and the pressure limit block causes the limit block to move, thereby driving the raw materials to continue to rise and contact the suction cup. The suction cup stably adsorbs the raw materials, and then the rotating motor is activated to drive the conveyor belt to rotate, thereby moving the raw materials to the bottom of the tank. In this way, the bottom sealing work of multiple tanks can be realized under the action of multiple suction cups, which improves the bottom sealing efficiency.

[0018] II. In this utility model, by setting the limiting unit, the snap-fit ​​plate can be pulled out of the fixed frame. Then, multiple tanks are placed in the limiting seat. With the help of the elastic force of the second elastic column and the second spring, the two arc-shaped plates are driven to move closer to each other until they are in contact with the outside of the tank. Then, the snap-fit ​​plate is snapped with the telescopic column and the horizontal plate. This ensures the stability of the snap-fit ​​plate and the limiting seat. The starting cylinder drives the telescopic column to descend, which in turn drives the limiting seat and the tank to descend stably, thus optimizing the stability of the bottom sealing.
