Description

Technical Field

[0001] The utility model relates to the technical field of ziplock bags, and more specifically, to a ziplock bag opening auxiliary device. Background Art

[0002] A ziplock bag is a common plastic bag with a self-adhesive seal that allows it to be closed without the use of tape or other sealing materials. When a ziplock bag is used for filling, an opening device is usually required to assist the operation. This device extends the jaws of an opening clamp into the ziplock bag and then stretches it open, and then other items are filled into the ziplock bag. However, in order not to damage the ziplock bag, the opening force generated by the opening clamp is usually set according to the size of the ziplock bag, so that it can be just stretched and fixed without damaging the ziplock bag. When filling, items on the platform are usually pushed into the ziplock bag. This may cause the ziplock bag to fall off the clamp after the items are pushed to the bottom of the ziplock bag due to insufficient stretching force. The fallen ziplock bag may get stuck in other parts of the machine, causing safety hazards and reducing production efficiency. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a ziplock bag opening auxiliary device to solve the problem that the opening clamp of the opening device relies solely on the opening force generated by itself to fix the ziplock bag, which may cause the ziplock bag to fall off during filling, thereby creating a safety hazard and reducing production efficiency.

[0026] It also includes a feeding device 4 and a conveyor belt 5. The feeding device 4 is fixedly installed on the top of the equipment installation plate 1, and the conveyor belt 5 is fixedly installed on the top of the equipment installation plate 1.

[0027] Among them, the feeding device 4 includes a feeding rack 41, a cylinder 42, a movable push block 43, a hanging rail 44, and an electric baffle 45. The feeding rack 41 is fixedly installed on the top of the equipment mounting plate 1, the cylinder 42 is fixedly connected to the bottom of the feeding rack 41, the movable push block 43 is movably installed on the top of the hanging rail 44, one end of the movable push block 43 is fixedly connected to the driving end of the cylinder 42, the hanging rail 44 is fixedly connected to the bottom of the feeding rack 41, and the electric baffle 45 is fixedly installed on the outer surface of the feeding rack 41; the electric baffle 45 is composed of an electric telescopic rod and a baffle, and the movement of the ziplock bag can be restricted by adjusting the spacing of the baffle to prevent position deviation.

[0028] The working process of this utility model is as follows:

[0029] After the equipment is turned on, the suction device at one end of the multifunctional mobile clamp group 2 will suck up the ziplock bag and place it on the feeding device 4. The staff can open the electric baffle 45 to adjust the baffle spacing according to the size of the ziplock bag, and then the cylinder 42 is started to push the movable push block 43 to move on the hanging rail 44, so that the exposed part of the movable push block 43 pushes the ziplock bag to the sealing suction opening position, so as to ensure that the sealing positions of ziplock bags of different sizes can be accurately delivered to the center position of the sealing suction and opening disk during the feeding process, and then the lower sealing suction and opening disk sucks the bottom of the ziplock bag, and the upper sealing suction and opening disk opens the ziplock bag, and the opening clamp on the multifunctional mobile clamp group 2 will extend into the opening of the ziplock bag and then open it. The clamp is opened to stretch the ziplock bag. After stretching, the clamp moves inward with the ziplock bag to prepare for filling. At this time, the double-headed threaded rod 313 is driven to rotate by turning on the motor 312, so that the two sets of moving blocks 314 move under the limiting action of the component housing 311, thereby reducing the distance between them. Subsequently, the distance between the two sets of clamping arms 32 is reduced so that the suction cup 33 contacts the side of the ziplock bag and is close to the stretched clamp. The air pump 35 is started to suck out the air in the suction cup 33 through the connecting pipe 34, so that negative pressure is generated inside the suction cup 33 to suck the ziplock bag tightly, ensuring that the ziplock bag will not fall during the filling operation. After the filling is completed, the adsorption and clamping are released, and the ziplock bag falls onto the conveyor belt 5 below and is transported to the next work area.
