[0002] In the modern packaging industry, many products, such as food, medicine, and cosmetics, require the removal of air from the container during packaging to extend the shelf life and prevent oxidation and mildew. Vacuuming technology can effectively remove air from the container and create a vacuum environment, thereby protecting the quality of the goods and is widely used in the packaging process.

[0003] At present, the common vacuum packaging equipment on the market usually adopts a single-head design, that is, the equipment has only one vacuum device and a capping mechanism. This design can meet the needs when processing smaller batches or individual packages. However, for medium and high batch production lines, the single-head equipment has low working efficiency and cannot process multiple containers at the same time, resulting in low production efficiency. In addition, the capping and vacuuming steps of existing equipment are usually performed separately, resulting in a long operation cycle and high manual intervention. Therefore, a double-head vacuum capping device is proposed to solve the above problems. Utility Model Content

[0025] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0026] Reference Figure 1-Figure 2 As shown, a double-head vacuum capping device includes a housing 1, a conveyor belt 2 is provided at the bottom inner end of the housing 1, and two sets of sliding and lifting components 3 are provided on the rear inner wall of the housing 1;

[0027] Among them, the sliding lifting assembly 3 includes a first electric slide rail 301 fixedly connected to the rear inner wall of the casing 1, a slide seat 302 is slidably connected to the first electric slide rail 301, the upper end of the slide seat 302 is fixedly connected to the first support frame 303, the lower end of the first support frame 303 is fixedly connected to two symmetrically distributed support rods 304, the upper end of the first support frame 303 is fixedly connected to the cylinder 305, the output end of the cylinder 305 passes through the upper end of the first support frame 303 and is fixedly connected to the lifting seat 306, the lifting seat 306 is slidably connected to the outer surface of the support rod 304, the lower end of the lifting seat 306 is fixedly connected to the fixed frame 307, the inner side of the fixed frame 307 is provided with a vacuum screw cover assembly 4, and the right side of the first support frame 303 is provided with an auxiliary limit assembly 5.

[0028] Furthermore, the first electric slide rail 301 is composed of a slide groove, a screw rod and a motor. The screw rod is rotatably connected to the inside of the slide groove. The motor is used to drive the screw rod to rotate. The slide 302 is threadedly connected to the outer surface of the screw rod. The motor drives the screw rod to rotate, and then drives the slide 302 to move linearly.

[0029] Furthermore, the conveyor belt 2 is used to transport bottle-shaped containers, the first electric slide rail 301 is used to adjust the horizontal position of the vacuum screw cap assembly 4, the cylinder 305 is used to adjust the vertical position of the vacuum screw cap assembly 4, and the support rod 304 guides the movement of the lifting seat 306.

[0030] Reference Figure 2-Figure 4 As shown, the vacuum screw cap assembly 4 includes a sealing cylinder 401 fixedly connected to the inner side of the fixing frame 307, the upper end of the sealing cylinder 401 is fixedly connected to the mounting cylinder 402, the upper end of the sealing cylinder 401 is located on the outside of the mounting cylinder 402 and is fixedly connected to the exhaust pipe 403, and the exhaust pipe 403 is connected to the interior of the sealing cylinder 401.

[0031] Furthermore, the upper end of the sealing cylinder 401 is located on the inner side of the mounting cylinder 402 and is fixedly installed with a drive motor 406. The upper end of the drive motor 406 passes through the upper end of the sealing cylinder 401 and is fixedly connected to a screw capping head 407. The shape and size of the lower end of the screw capping head 407 match the bottle mouth and bottle cap of the bottle-shaped container to be processed. The screw capping operation can be performed by driving the screw capping head 407 to rotate by the drive motor 406.

[0032] Furthermore, an airbag mounting groove 404 is provided on the inner side of the sealing cylinder 401, and an inflation port 405 is provided on the outer surface of the sealing cylinder 401. The inflation port 405 is connected to the airbag mounting groove 404. An inflatable airbag is provided in the airbag mounting groove 404. The inflation port 405 is used to connect the airbag and the air source. When the cylinder 305 drives the sealing cylinder 401 to descend to the bottle mouth of the bottle-shaped container, the airbag is inflated through the inflation port 405 so that the airbag abuts against the surface of the bottle-shaped container, thereby forming a closed environment inside the sealing cylinder 401. The size of the airbag can be replaced according to the diameter of the bottle mouth.

[0033] Furthermore, a vacuum pump 408 is fixedly installed on the front side of the first support frame 303. The input end of the vacuum pump 408 is connected to the exhaust pipe 403 through a flexible pipe. When the air bag abuts against the surface of the bottle-shaped container to form a closed environment inside the sealing tube 401, the vacuum pump 408 draws the air inside the sealing tube 401 to perform a vacuum operation.

[0034] Furthermore, the auxiliary limiting assembly 5 includes a second support frame 501 fixedly connected to the right side of the first support frame 303, and the lower end of the second support frame 501 is fixedly connected to a second electric slide rail 502, and two symmetrically distributed clamping jaws 503 are slidably connected to the second electric slide rail 502. The second electric slide rail 502 is composed of a slide groove, a bidirectional screw rod and a motor. The motor is used to drive the screw rod to rotate. The two clamping jaws 503 are threadedly connected to the outer surface of the bidirectional screw rod. The bidirectional screw rod is driven to rotate by the motor, which can make the two clamping jaws 503 approach or move away from each other to realize clamping and releasing operations. The clamping jaws 503 are used to fix the bottle-shaped container during the capping and vacuuming operations.

[0035] Furthermore, the end of the clamping claw 503 away from the second electric slide rail 502 is in an arc shape, and the arc shape can better fit the surface of the bottle-shaped container to achieve a better clamping effect.

[0036] Furthermore, the conveying speed of the conveyor belt 2, the position adjustment of the vacuum capping assembly 4 and the vacuuming operation of the capping, as well as the retraction and extension of the clamping jaws 503 are all controlled by an external programmable logic controller.

[0037] Working principle: When in use, the conveyor belt 2 will place the bottle container with the bottle cap on the upper end for transportation, and the two first electric slide rails 301 will respectively drive the two auxiliary limit assemblies 5 to approach the surface of the bottle container, and the two clamping claws 503 of the auxiliary limit assemblies 5 will be placed on both sides of the bottle container, and then tightened for clamping. After the clamping is completed, the cylinder 305 drives the vacuum screw cap assembly 4 to descend to the bottle mouth of the bottle container, and the screw capping head 407 contacts the bottle cap. At this time, the air bag is inflated through the air source and the inflation port 405, so that the air bag contacts the surface of the bottle container to form a closed environment, and then the vacuum pump 408 is started to vacuum the bottle container. After the vacuum operation is completed, the drive motor 406 rotates immediately, driving the screw capping head 407 to rotate to perform the screw capping operation. After the vacuum and screw capping operations are completed, the air bag and the clamping claws 503 is released, the cylinder 305 and the first electric slide 301 drive the device to reset and cycle the above operations. During the entire vacuuming and capping process, the bottle-shaped container is continuously transported along the conveyor belt 2. When the two clamps 503 clamp the bottle-shaped container, the first electric slide 301 will drive the vacuum capping assembly 4 to move along the movement direction of the conveyor belt 2 at the same conveying rate as the conveyor belt 2. At this time, the bottle-shaped container and the auxiliary limit assembly 5 and the vacuum capping assembly 4 are in a relatively static state, thereby ensuring that the vacuuming and capping operations can be carried out stably. The two vacuum capping assemblies 4 respectively perform vacuuming and capping operations on the staggered bottle-shaped containers. A reasonable working rhythm is set by an external programmable logic controller, so that the processing speeds of the conveyor belt 2 and the two vacuum capping assemblies 4 cooperate with each other, which can achieve automated production with higher processing efficiency.
