Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a vacuum suction cup structure for pesticide powder packaging bag packaging equipment. Background Technology

[0002] Pesticide powder is a powdered preparation made by mixing, pulverizing and blending active ingredients, fillers and a small amount of adjuvants to a certain fineness. Due to its advantages such as convenient use, fine particles, high application efficiency and low processing cost, pesticide powder is one of the main formulations of pesticides. After the pesticide powder is packaged into bags, it needs to be sealed using sealing equipment. After sealing, the sealed bags are transferred to a conveyor belt by a vacuum suction cup mechanism for subsequent processing.

[0003] Existing vacuum suction cup mechanisms require airflow to be introduced through the air inlet on the vacuum suction cup for suction. However, dust in the outside air can easily enter the vacuum suction cup, and after long-term use, it can easily cause the suction port on the vacuum suction cup to become blocked, thus affecting the suction effect of the vacuum suction cup. Therefore, in order to solve the above defects, the inventors propose a vacuum suction cup structure for pesticide powder packaging bag sealing equipment. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] This utility model discloses a vacuum suction cup structure for a pesticide powder packaging bag sealing device, such as... Figure 1-5 As shown, the equipment includes a packaging device body 1 for sealing pesticide powder packaging bags and a conveyor belt 3. A support plate 4 is fixedly installed on the outer surface of the packaging device body 1 on one side of the conveyor belt 3. A rotating shaft 401 is rotatably connected to one side of the outer surface of the support plate 4, and a rotating plate 412 is fixedly installed at one end of the rotating shaft 401. When the rotating shaft 401 rotates, it will drive the rotating plate 412 to rotate.

[0021] Two connecting plates 411 are fixedly installed on one side of the outer surface of the rotating plate 412, and a connecting pipe 201 is fixedly installed on the end of the two connecting plates 411 away from the rotating plate 412. A suction cup 2 is fixedly installed at the opening of the connecting pipe 201. The suction cup 2 can adsorb the sealed pesticide packaging bag, and rotating the rotating plate 412 will drive the two connecting plates 411 to rotate, which will drive the adsorbed pesticide packaging bag to rotate onto the conveyor belt 3 and place it on the conveyor belt 3 for transfer.

[0022] Telescopic sleeves 203 are fixedly installed on both sides of the outer surface of the connecting pipe 201, and a first spring 205 is fixedly installed on the opposite side inside the two telescopic sleeves 203. An installation head 206 is fixedly installed on the opposite end of the two first springs 205. When the installation head 206 moves toward one side of the first spring 205, it will squeeze the first spring 205.

[0023] Furthermore, each of the two mounting heads 206 is fixedly mounted with a movable rod 204 at one end of the first spring 205. The two movable rods 204 pass through the interior of the two first springs 205 respectively. The interior of the connecting pipe 201 is provided with a filter plate 202, and mounting holes 207 are opened on both sides of the outer surface of the filter plate 202. By pulling the two movable rods 204 outward toward the telescopic sleeve 203, the two mounting heads 206 can be driven to squeeze the two first springs 205, so that the two mounting heads 206 can be pulled out from the mounting holes 207. Then the filter plate 202 can be disassembled to clean the dust filtered on the filter plate 202.

[0024] A sealing cap 2011 is fitted over the opening of the suction cup 2. The sealing cap 2011 can seal the opening of the suction cup 2 when it is not in use, so as to prevent impurities or dust from entering the suction cup 2 when it is not in use.

[0025] Two threaded rods 2012 are threadedly connected to one side of the sealing cover 2011, and a fixing plate 2013 is rotatably connected to the opposite end of each of the two threaded rods 2012. Two telescopic rods 2014 are fixedly installed on opposite sides inside the sealing cover 2011, and the four telescopic rods 2014 are fixedly connected to the two fixing plates 2013 respectively. Rotating the threaded rods 2012 can push the fixing plates 2013 to move. When the fixing plates 2013 move, they will drive the two telescopic rods 2014 to extend and retract. When the two fixing plates 2013 move towards the outer surface of the connecting pipe 201 at the same time, the connecting pipe 201 can be clamped and fixed so that the sealing cover 2011 is installed on the connecting pipe 201.

[0026] A portion of each of the two movable rods 204 is located inside the two telescopic sleeves 203, and the other portion of each of the two movable rods 204 is located outside the two telescopic sleeves 203. A handle is fixedly installed at the end of each movable rod 204 located outside the telescopic sleeve 203.

[0027] A gear 402 is fixedly installed at the end of the rotating shaft 401 away from the rotating plate 412. When the gear 402 rotates, it can drive the rotating shaft 401 to rotate.

[0028] A support plate 4 is fixedly mounted on one side of the gear 402 with a fixed bracket 403, and a slide rod 404 is fixedly mounted inside the fixed bracket 403. A rack 406 is slidably connected to the outer surface of the slide rod 404, and the rack 406 meshes with the gear 402. The rack 406 can slide on the outer surface of the slide rod 404. When the gear 402 rotates, it can push the rack 406 to move.

[0029] A second spring 405 is fixedly installed on one side of the inner side of the fixing frame 403, and a slide rod 404 passes through the inside of the second spring 405. The second spring 405 is fixedly connected to the rack 406. When the rack 406 moves toward one side of the second spring 405, it will compress the second spring 405.

[0030] A connecting rod 407 is fixedly installed on the top surface of the rack 406, and the connecting rod 407 is slidably connected to the fixed frame 403. When the connecting rod 407 moves, it will drive the rack 406 to move.

[0031] One end of the connecting rod 407 extending to the outside of the fixed frame 403 is rotatably connected to a movable wheel 408. A cam 409 is rotatably connected to the outer surface of the support plate 4 located on one side of the gear 402. A micro motor 410 is fixedly installed on the outer surface of the support plate 4 located on one side of the rotating plate 412. The output end of the micro motor 410 is fixedly connected to the cam 409. When the cam 409 rotates, it will cooperate with the second spring 405 to make the connecting rod 407 drive the rack 406 to reciprocate left and right, thereby driving the gear 402 to reciprocate, so that the gear 402 drives the suction cup 2 to reciprocate between the packaging equipment body 1 and the conveyor belt 3 in two directions.

[0032] An air supply cylinder 4011 is fixedly installed on the outer surface of the support plate 4 on one side of the gear 402, and an air supply pipe 4014 is fixedly installed on one side of the outer surface of the air supply cylinder 4011. The air supply pipe 4014 is fixedly connected to the connecting pipe 201. An electric push rod 4012 is fixedly installed on the outer surface of the support plate 4 on one side of the gear 402, and a piston 4013 is fixedly installed on the piston rod 4013 of the electric push rod 4012. The piston 4013 is located inside the air supply cylinder 4011. The electric push rod 4012 pushes the piston 4013 to move inside the air supply cylinder 4011, so that the suction cup 2 can adsorb the packaging bag containing pesticide powder.

[0033] The working principle of this utility model is as follows: After the packaging equipment body 1 seals the packaging bag containing pesticide powder, the micro motor 410 drives the cam 409 to rotate, so that the connecting rod 407 drives the rack 406 to move, which in turn drives the gear 402 and the rotating shaft 401 to rotate, rotating the suction cup 2 to contact the pesticide packaging bag. Then, the electric push rod 4012 drives the piston 4013 to move inside the air supply cylinder 4011, drawing air from the suction cup 2 into the air supply cylinder 4011, so that the suction cup 2 adsorbs the pesticide packaging bag. After adsorption, as the cam 409 continues to rotate, the suction cup 2 can drive the adsorbed pesticide packaging bag. After moving to the top of the conveyor belt 3, the electric actuator 4012 pushes the piston 4013 again to move inside the air cylinder 4011, so that the air in the air cylinder 4011 is blown into the suction cup 2, causing the pesticide packaging bag to fall onto the conveyor belt 3. During this process, the filter plate 202 can effectively prevent dust and impurities in the air from entering the air supply pipe 4014 with the air. When the suction cup 2 is not in use, the threaded rod 2012 is rotated so that the two fixing plates 2013 clamp and fix the outer surface of the connecting pipe 201, so that the sealing cover 2011 seals the opening of the suction cup 2 to prevent dust from entering the suction cup 2 when it is not in use.
