[0010] Beneficial effects

[0011] Compared with the prior art, the present invention has at least the following advantages:

[0012] 1. The bag-taking mechanism of this utility model takes the bag from the bag-feeding mechanism at the top and flips the packaging bag to a vertical position to prepare for the subsequent external vacuum nozzle to suck up the packaging bag.

[0013] 2. The external vacuum nozzle has a dual function: on the one hand, it can reliably pick up packaging bags from the bag-picking mechanism; on the other hand, it works efficiently with the internal vacuum nozzle to complete the bag-opening action. This structural design simplifies the equipment structure.

[0014] 3. The external vacuum nozzle and bag clamping mechanism adopt a synchronous left-right movement design, working seamlessly together with the bag picking mechanism, external vacuum nozzle, bag clamping gripper, and sealing mechanism to form a complete automated process. From bag picking, opening, feeding to sealing, each process is arranged in a horizontal linear layout. This layout greatly optimizes the space utilization of the equipment, effectively reducing the floor space required compared to traditional multi-station rotary packaging machines.

When the dual-axis cylinder 19 is working, the two sliders 16 can move towards each other and away from each other as the two output ends of the dual-axis cylinder 19 move, so that the two bag-clamping grippers 12 move closer or further away from each other.

[0028] An inner suction bag mechanism 18 is provided below the slide rail 14. The inner suction bag mechanism 18 has multiple inner vacuum nozzles 182 that can move back and forth. Specifically, the inner vacuum nozzles 182 are mounted on an inner vacuum nozzle seat 181, and the inner vacuum nozzle seat 181 is connected to the output end of the suction bag cylinder 180 fixed inside the inner body 17.

An inner sealing plate 130 is fixed to the output end of the sealing cylinder 132. The output end of the sealing cylinder 133 movably passes through the inner sealing plate 130, and an outer sealing plate 131 is fixed to its end. Under the action of the sealing cylinder 133 and the sealing cylinder 132, the outer sealing plate 131 and the inner sealing plate 130 can move towards each other and away from each other. A heat sealing strip is provided at the bottom of the inner wall of both the inner sealing plate 130 and the outer sealing plate 131. The heat sealing strip heats up when energized to seal the packaging bag.

[0030] The inner body 17 is provided with a clamping mechanism 9 that can move left and right. A connecting arm 10 is provided on the left side of the clamping mechanism 19. A T-shaped external vacuum nozzle seat 11 is installed at the end of the connecting arm 10.

A bracket 91 is fixed on the slide of the linear slide 90. Two bag clamping cylinders 92 and 93 are fixed on the bracket 91. The two bag clamping cylinders 92 are arranged on both sides of the bag clamping cylinder 93. An inner bag clamping plate 94 is fixed to the end of the bag clamping cylinder 92. The output end of the bag clamping cylinder 93 moves through the inner bag clamping plate 94 and an outer bag clamping plate 95 is fixed to its end. The inner bag clamping plate 94 and the outer bag clamping plate 95 are parallel. Guide rods 96 are fixed on both sides of the bottom of the inner side of the outer bag clamping plate 95. The guide rods 96 move through the inner bag clamping plate 94. Under the action of the bag clamping cylinders 93 and 92, the outer bag clamping plate 95 and the inner bag clamping plate 94 can move towards each other and away from each other.

[0031] The outer unit 1 has a feeding structure 4 on its top, and a feeding ramp 20 located at the bottom right side of the inner unit 17. The outer unit 1 has a control console on its top, which houses a controller, and a display screen is located in front of the console. The controller is electrically connected to each drive component and is used to control the operation of each drive component. The outer unit 1 has a viewing door on its front side, and the viewing door 2 on its right side has a discharge port 6 corresponding to the position of the feeding ramp.

[0032] It should be noted that when the clamping mechanism 9 moves below the sealing mechanism 13, the outer vacuum nozzle 110 is located in front of the inner vacuum nozzle. When the clamping mechanism 9 moves to the position of the inner vacuum nozzle 8, the outer vacuum nozzle 110 is located in front of the bag taking mechanism 8.

[0033] Working principle:

[0034] Step 1: The bag feeding mechanism 3 has multiple stacked packaging bags. The bottom of the bag feeding mechanism 3 is provided with a bag picking port 30. When the mounting plate 84 is horizontal, it is located below the bag picking port 30. The bag picking vacuum nozzle is connected to a vacuum source and picks up the packaging bag at the bottom from the bag picking port 30. Then the output end of the bag picking cylinder 80 moves upward, so that the mounting plate 84 drives the packaging bag from a horizontal to a vertical state.

[0035] Step 2: The linear slide 90 operates, causing the clamping mechanism 9 to move to the position of the inner vacuum nozzle 8. At the same time, the bag clamping cylinders 1 and 2 operate, causing the inner bag clamping plate 94 and the outer bag clamping plate 95 to move towards each other. The outer vacuum nozzle 110 moves inward with the outer bag clamping plate 95. At this time, the outer vacuum nozzle 110 adsorbs the packaging bag on the bag picking mechanism, and the clamping mechanism 9 clamps the top of the packaged bag that has been picked up by the bag clamping claw.

[0036] Step 3: When the linear slide 90 operates, the clamping mechanism 9 moves to below the sealing mechanism 13, and the outer vacuum nozzle 110 adsorbs the packaging bag located in front of the inner vacuum nozzle.

[0037] Step 4: The dual-axis cylinder 19 operates, causing the two bag-clamping grippers 16 to come close to each other and clamp the top two sides of the packaging bag adsorbed by the outer vacuum nozzle 110. The suction cylinder 180 causes the inner vacuum nozzle 182 to move forward and adsorb the inner side of the packaging bag.

[0038] Step 5: The inner sealing plate 130 and the outer sealing plate 131 of the sealing mechanism move towards each other to clamp and heat seal the top of the packaging bag clamped by the clamping mechanism; then the outer clamping plate 95 and the inner clamping plate 94 of the clamping mechanism move away from each other to release the clamping of the packaging bag; the outer vacuum nozzle moves outward with the outer clamping plate 95, and the inner vacuum nozzle 182 moves inward under the action of the suction cylinder 180. The outer vacuum nozzle 110 and the inner vacuum nozzle 182 cooperate and move away from each other, thereby opening the packaging bag, and the material falls into the packaging bag from the feeding mechanism through the guide nozzle.

[0039] Step 6: The outer vacuum nozzle 110 moves to the left along with the clamping mechanism 9, and the inner sealing plate and outer sealing plate of the sealing mechanism move in opposite directions, so that the sealed packaging bag falls into the feeding inclined plate and slides out from the discharge port.

[0040] Step 7: Repeat the above actions to complete the continuous packaging of materials.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
