Description

Technical Field

[0001] This utility model relates to the technical field of material feeding and bag receiving, specifically to an automatic material feeding and bag receiving device. Background Technology

[0002] The material feeding and bag receiving equipment is an automated device that integrates material feeding, sorting, bag receiving, and sealing. It is used to form regular stacks of loose or bulk materials by the material feeding mechanism, and then accurately guide them into pre-made packaging bags by the bag receiving mechanism and seal them.

[0003] To this end, patent CN110239008B discloses an automatic feeding device, comprising a feeding mechanism, a feeding mechanism, and a semi-finished electrical box. The feeding mechanism includes a feeding frame, a cross slide mounted on the feeding frame, a vertical lifting mechanism mounted on the cross slide for horizontal and vertical movement, a clamping assembly mounted on the vertical lifting mechanism for holding the semi-finished electrical box, and a first servo motor mounted on the vertical lifting mechanism for driving the clamping assembly to move up and down. The feeding mechanism includes a feeding body, a feeding groove mounted on the feeding body for holding the semi-finished electrical box, a sliding ramp mounted inside the feeding body, a feeding head mounted above the feeding groove, a second servo motor for driving the feeding head to perform feeding operations, and photosensitive mechanisms mounted on both sides of the feeding groove. This automatic feeding device has a high degree of automation and can quickly remove the product to be processed from the mold.

[0004] The existing technical solutions mentioned above have the following drawbacks: current material feeding and bag receiving equipment disperses the material by tapping it, but material feeding and bag receiving equipment requires the material to be fed into the packaging bag and then tapped to expel the air inside the packaging bag. Utility Model Content

[0005] The purpose of this invention is to provide an automatic material feeding and bag receiving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic bag receiving device, comprising a conveyor belt, a bag receiving frame body and an mounting frame, wherein a connecting frame is fixed at the bottom of the bag receiving frame body, and a fixed roller is rotatably connected to the upper surface of the connecting frame; a support frame is fixed at the bottom of the bag receiving frame body, and a motor is mounted on the upper surface of the support frame, and a rotating roller is rotatably connected to the upper surface of the motor.

[0007] When using the automatic bag-feeding device in this technical solution, loosen the locking bolts, slide the slide plate according to the actual length of the packaging bag, and the slide plate drives the fixed plate to slide. The height of the fixed plate can be adjusted according to the actual length of the packaging bag. After adjusting to a suitable height, tighten the locking bolts. The hydraulic cylinder inside the support rod drives the hydraulic rod to move, the hydraulic rod drives the mounting rod to move, and the mounting rod drives the tapping plate to move. The tapping plate can tap the packaging bag to expel the air inside the packaging bag, making it easier to expel the air.

[0008] Preferably, a conveyor belt is fitted onto the outer surfaces of the rotating roller and the fixed roller, and a fixing frame is inserted into the upper surface of the conveyor belt. The rotating roller and the fixed roller form a closed loop, so that the conveyor belt maintains constant tension throughout its entire stroke, avoiding deviation or slippage and ensuring smooth material conveying.

[0009] Preferably, a limit rod is threadedly connected to the lower surface of the fixed frame, and a mounting bracket is fixed to the lower surface of the limit rod. The limit rod and the fixed frame are connected by a threaded pair, which allows for axial micro-adjustment without disassembling the overall mechanism, ensuring the alignment of the mounting bracket with the downstream workstation and reducing cumulative errors.

[0010] Preferably, both outer end faces of the mounting bracket are fixed with outer rods, and an inner rod is movably inserted into one outer end face of the outer rod. The inner rod can slide and extend within the outer rod, achieving stepless length adjustment. This allows for compatibility with downstream workstations of different widths or spacings without replacing parts, improving the equipment's versatility.

[0011] Preferably, a support plate is fixed to one outer end face of the inner rod, and a sliding rod is fixed to one outer end face of the support plate. The support plate extends the cantilever end of the inner rod into a surface-to-surface connection, significantly increasing the moment of inertia of the section. The sliding rod is then fixed to the support plate to form an integral beam structure, effectively suppressing bending deformation and vibration during high-speed operation and improving positioning accuracy.

[0012] Preferably, a clamping plate is slidably connected to the outer surface of the slide rod, and both outer end faces of the clamping plate are threaded with fixing bolts. The clamping plate can slide freely along the axial direction on the slide rod to achieve continuous and precise position adjustment; after reaching the desired position, it is locked by the double-sided threaded fixing bolts to eliminate gaps and ensure repeatability of positioning accuracy.

[0013] Preferably, a fixing plate is slidably connected to the inner wall of the bag receiving frame body, and a connecting plate is fixed to the upper surface of the fixing plate. The fixing plate and the bag receiving frame body are engaged by a sliding pair, which can move steplessly along the bag opening in the lateral or longitudinal direction, quickly adapting to packaging bags of different widths, lengths or folding forms, without the need to change special fixtures, significantly improving changeover efficiency.

[0014] Preferably, a sliding plate is welded to the upper surface of the fixing plate, and a locking bolt is threaded to one outer end face of the sliding plate. The sliding plate and the fixing plate are welded together to form an integral rigid beam, eliminating the small gaps and loosening risks of traditional bolted connections, effectively suppressing vibrations during high-speed bag receiving, and improving positioning stability.

[0015] Preferably, a support rod is fixed to one outer end face of the connecting plate, and an installation rod is movably inserted into one outer end face of the support rod. A clapper is fixed to one outer end face of the installation rod. The support rod and the installation rod are movably inserted, allowing the clapper to be pulled out separately without disassembling the connecting plate, enabling the replacement of vulnerable parts in seconds and significantly reducing downtime.

[0016] Preferably, hydraulic cylinders are installed on the inner walls of both the support rod and the outer rod, and a hydraulic rod is movably inserted into one outer end face of the hydraulic cylinder. The hydraulic rod is connected to the mounting rod and the inner rod. The hydraulic cylinder has a large output force and is linearly adjustable. Combined with closed-loop pressure-displacement control, it can enable the clapper and the bag clamping mechanism to achieve millimeter-level precise stroke, avoid mechanical limit impact, and improve the repeatability accuracy of the action.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model achieves the effect of easily expelling air by setting up a sliding plate, support rod, and clapping plate. Loosen the locking bolt, slide the sliding plate according to the actual length of the packaging bag, and the sliding plate drives the fixed plate to slide. The height of the fixed plate can be adjusted according to the actual length of the packaging bag. After adjusting to a suitable height, tighten the locking bolt, and the hydraulic cylinder inside the support rod drives the hydraulic rod to move. The hydraulic rod drives the mounting rod to move, and the mounting rod drives the clapping plate to move. The clapping plate can tap the packaging bag to expel the air inside the packaging bag, making it easy to expel air.

[0019] 2. This utility model achieves the effect of ensuring stable material conveying by setting up a fixed roller, a rotating roller, and a conveyor belt. The motor can drive the rotating roller to rotate, the rotating roller can drive the conveyor belt to rotate, the conveyor belt can drive the fixed roller to rotate, the rotating conveyor belt can drive the fixed frame to move, and the fixed frame can drive the packaging bag to move. The rotating roller and the fixed roller form a closed loop, so that the conveyor belt maintains constant tension throughout the entire stroke, avoids deviation or slippage, and ensures stable material conveying.

[0020] 3. This utility model, by setting up a clamping plate, a support plate, and an inner rod, achieves the effect of simultaneously expelling air and clamping the packaging bag. Insert the opening of the packaging bag into the clamping plate and the support plate, loosen the fixing bolt, hold the clamping plate, and slide it to the side of the bag opening. Tighten the fixing bolt, and the clamping plate can clamp the bag opening, making it easy to fix the packaging bag. After expelling the air, the hydraulic cylinder inside the outer rod drives the hydraulic rod to move, the hydraulic rod drives the inner rod to move, the inner rod drives the support plate and the clamping plate to move, and the support plate and the clamping plate drive the packaging bag to move, making it easy to expel air and clamp the packaging bag at the same time.
