[0001] This utility model relates to the field of feeding device technology, specifically to a liquid packaging machine with quantitative feeding function. Background Technology

[0002] Liquid packaging machines are automated equipment used for filling and packaging liquid products such as soy sauce, vinegar, juice, and milk. They have functions such as bag making, quantitative filling, sealing and cutting, and printing production dates. They are widely used in the food, beverage, daily chemical, and pharmaceutical industries. Their highly automated design can complete the entire process from film forming to finished product output.

[0003] In the feeding area of ​​a liquid packaging machine, a material collection box is usually required to collect the packaged bags. Additional operators are needed to frequently sort the bags in the material collection box to prevent excessive stacking of bags in certain areas and to prevent the bags from overflowing. This is quite labor-intensive. Therefore, a liquid packaging machine with quantitative feeding is proposed to solve the above problems. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions: A liquid packaging machine with quantitative feeding includes a liquid packaging machine, wherein a feeding mechanism is provided below the feeding area of ​​the liquid packaging machine, and the feeding mechanism includes gears; The feeding mechanism includes a single-layer platform scale. Support rails are fixedly installed on both sides of the top surface of the single-layer platform scale near the long side. Each support rail is also fixedly connected to a baffle on the side away from the middle of the single-layer platform scale. Each of the baffles has a groove in the middle of its surface, and the groove is consistent with the baffle in the length direction. In this design, slider 1 is slidably connected to both ends of the inner side of the front slide groove, and slider 2 is slidably connected to both ends of the inner side of the rear slide groove. A push rod is connected through slider 1 and slider 2, which are located in opposite positions.

[0005] As a further embodiment of this utility model: a retaining ring is fixedly connected to one end of the push rod, and a threaded structure is provided at the other end of the push rod. A nut is threadedly fitted on the side of the push rod away from the retaining ring. The surface of the retaining ring abuts against the first slider, and the surface of the nut abuts against the second slider.

[0006] As a further embodiment of this utility model: the bottom surfaces of the two sliders are connected to a rack, and the bottom surfaces of the rack are meshed with a gear. The gear is located at the central pivot and is fixedly connected to the output shaft of the servo motor. A bracket is fixedly installed on the outer wall of the servo motor, and the bottom surface of the bracket is fixedly connected to the top surface of the single-layer platform scale.

[0007] As a further embodiment of this utility model: several sliding rollers are rotatably connected to the inner side of the middle of the two support rails, and each sliding roller is equidistant along the length direction of the support rail, with the top of each sliding roller extending above the support rail.

[0008] As a further embodiment of this utility model: the top of the sliding wheel supports and movably contacts a collection box, and the two sides of the collection box abut against the middle of each push rod.

[0009] As a further embodiment of this utility model: a plurality of extension blocks are fixedly connected to the upper part of the baffle and the side near the collection box. Each of the extension blocks is arranged at equal intervals along the length direction of the baffle, and each of the extension blocks is rotatably connected to a side pulley on the side away from the baffle. The surface of the side pulley abuts against the collection box.

[0010] As a further embodiment of this utility model: a control panel is fixedly installed at the front end of the single-layer platform scale, and the control panel is electrically connected to the single-layer platform scale, the servo motor, and the liquid packaging machine. A guide slope is fixedly installed on one side of the single-layer platform scale, and the top of the guide slope is flush with the top of each sliding wheel.

[0011] The beneficial effects of this utility model are: (1) The present invention sets a single-layer platform scale under the collection box, which can weigh the packaging bags inside the collection box. The weighing data is displayed through the control panel, so that the operator can use more specific data to determine whether the collection box is fully loaded, thereby ensuring the quantitative feeding of the liquid packaging machine. (2) The output shaft of the servo motor is controlled to reciprocate through the control panel and the built-in microcontroller. This drives the push rods on both sides of the collection box to reciprocate synchronously through the transmission structure of gears and racks, thereby driving the collection box to slide back and forth above the single-layer platform scale. When the liquid packaging machine discharges, the packaging bags can fall into the collection box relatively evenly, which can effectively prevent the local packaging bags from accumulating too high in the collection box. (3) The push rods located on both sides of the collection box can be disassembled and pulled out, so that after the collection box is filled, the collection box can be moved freely along the guide slope above the single-layer platform scale, which facilitates the subsequent unloading steps.

Figure 2 , Figure 5 As shown, when nut 211 is tightened, nut 211 and retaining ring 218 are clamped on both sides of slider one 210 and slider two 212, thereby fixing the position of push rod 217; The bottom surfaces of the two sliders 212 are connected to a rack 213, and the bottom surface of the rack 213 is meshed with a gear 214. The gear 214 is located at the central pivot and is fixedly connected to the output shaft of the servo motor 215. A bracket 216 is fixedly mounted on the outer wall of the servo motor 215, and the bottom surface of the bracket 216 is fixedly connected to the top surface of the single-layer platform scale 201. Figure 4 As shown, the servo motor 215 can be a 1FT7 model servo motor, which is suitable for occasions where the output shaft frequently starts and stops and switches between forward and reverse rotation. Several sliding rollers 204 are rotatably connected to the inner sides of the middle of both support rails 203. Each sliding roller 204 is equidistant along the length of the support rail 203, and its top extends above the support rail 203. The top of each sliding roller 204 supports and movably contacts a collection box 219. The two sides of the collection box 219 abut against the middle of each push rod 217.

[0017] The working principle of this utility model: When in use, the liquid packaging machine 1 is started via the control panel 202. The liquid packaging machine, loaded with material, falls into the collection box 219. The control panel 202 drives the servo motor 215 to start and controls its output shaft to reciprocate. The gear 214 pushes the rack 213, causing the slider 212 to reciprocate linearly along the slide groove 209. The two push rods 217 clamp the collection box 219 and drive it to move back and forth relative to the outlet of the liquid packaging machine 1 on the top of the sliding roller 204, preventing the packaging from being damaged. The bags are partially piled up in the collection box 219. The weight of the packaging bags in the collection box 219 is displayed by the control panel 202 on the single-layer platform scale 201. When the collection box 219 reaches the predetermined weight, the control panel 202 stops the liquid packaging machine 1. Then the operator turns the nut 211 to disassemble it from the push rod 217. Then the push rod 217 is pulled towards the retaining ring 218. The push rod 217 can be separated from the slider 1 210 and slider 2 212. Then the collection box 219 is pushed to move out of the top of the single-layer platform scale 201 with the help of the guide slope 205.
