Description

Quantitative device for aseptic carton filling equipment Technical Field

[0001] This utility model relates to the field of quantitative filling technology for filling machines, specifically a quantitative device for aseptic carton filling equipment. Background Technology

[0002] Aseptic carton filling machines require precise control of the filling volume during the filling process to ensure product quality and stability. Most current aseptic carton filling equipment uses float-type liquid level control to address this issue; however, this float-type liquid level control is unsuitable for aseptic carton filling equipment using composite filling tubes.

[0003] For aseptic carton filling equipment using composite filling tubes, the filling volume is typically controlled by a valve-assisted filling followed by carton sealing. Specifically, after the carton is moved to the designated position, liquid is injected through the valve into the carton, and then a pressure seal is applied at a fixed point on the top of the carton. Simultaneously, excess liquid is squeezed into the adjacent carton above it to ensure a consistent filling volume for each carton. However, after liquid injection, the carton's sidewalls bulge outwards under gravity, causing deformation. When the carton is sealed, the actual filling volume inside is higher than the standard volume, affecting the stability of the product filling volume. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a quantitative device for aseptic carton filling equipment to support the side wall of the carton and avoid deformation of the carton during the filling process, which would affect the stability of the product.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quantitative device for aseptic carton filling equipment, including a hanging plate, a horizontal sealing mechanism disposed on the hanging plate, a side clamping mechanism and a quantitative plate mechanism disposed within the horizontal sealing mechanism, wherein the side clamping mechanism is used for supporting and shaping the outer wall of the carton, and the quantitative plate mechanism is used for quantitatively dispensing the liquid inside the carton.

[0006] Furthermore, the horizontal sealing mechanism includes an upper horizontal sealing plate and a lower horizontal sealing plate, wherein the upper horizontal sealing plate is fixed to the hanging plate.

[0007] Furthermore, the upper horizontal sealing plate is provided with first guide brackets on both sides, and the lower horizontal sealing plate is provided with second guide brackets on both sides. A horizontal sealing cylinder is provided on the second guide bracket, and the output end of the horizontal sealing cylinder is fixedly connected to the first guide bracket.

[0008] Furthermore, the metering plate mechanism includes a metering cylinder, two connecting rods connected to the output end of the metering cylinder, positive clamps respectively disposed on the connecting rods, and metering plates connected to the positive clamps. The two metering plates are arranged opposite to each other and are used to squeeze the paper box to meter the liquid inside the paper box.

[0009] Furthermore, the side clamping mechanism includes a side clamping cylinder and a side clamping plate disposed on the side clamping cylinder.

[0010] Furthermore, the side clamp is positioned between the two positive clamps.

[0011] Furthermore, the inner side of the upper horizontal sealing plate is provided with a sealing mechanism, which is used to squeeze and seal the opening at the top of the carton. The inner side of the lower horizontal sealing plate is provided with a cutting mechanism, which is used to cut the sealing opening of the carton.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Example:

[0029] As shown in Figures 1-7, the metering device for aseptic carton filling equipment includes a hanging plate 100, a horizontal sealing mechanism 200 mounted on the hanging plate 100, and a side clamping mechanism 300 and a metering plate mechanism 400 disposed within the horizontal sealing mechanism 200. The side clamping mechanism 300 is used to support and shape the outer wall of the carton, and the metering plate mechanism 400 is used to meter the liquid inside the carton. The side clamping mechanism 300 and the metering plate mechanism 400 support the side wall of the carton from four directions, ensuring that the side wall of the carton will not bend or deform during the filling process.

[0030] The horizontal sealing mechanism 200 includes an upper horizontal sealing plate 201 and a lower horizontal sealing plate 202. The upper horizontal sealing plate 201 is fixed to the hanging plate 100. First guide brackets 203 are provided on both sides of the upper horizontal sealing plate 201, and second guide brackets 204 are provided on both sides of the lower horizontal sealing plate 202. A horizontal sealing cylinder 205 is mounted on the second guide bracket 204, and the output end of the horizontal sealing cylinder 205 is fixedly connected to the first guide bracket 203. The upper horizontal sealing plate 201 and the lower horizontal sealing plate 202 are installed via the hanging plate 100 and connected by the first guide brackets 203 and the second guide brackets 204. Driven by the horizontal sealing cylinder 205, the lower horizontal sealing plate 202 moves upward along the first guide brackets 203 and the second guide brackets 204, approaching the upper horizontal sealing plate 201.

[0031] The inner side of the upper horizontal sealing plate 201 is provided with a sealing mechanism, which is used to squeeze and seal the opening at the top of the cardboard box. Because the squeezing position is fixed, excess liquid can be squeezed into the adjacent cardboard box above. The inner side of the lower horizontal sealing plate 202 is provided with a cutting mechanism, which is used to cut off the seal of the cardboard box.

[0032] The metering plate mechanism 400 includes a metering cylinder 401, two connecting rods 402 connected to the output end of the metering cylinder 401, the two connecting rods 402 being rotatably connected by meshing, positive clamps 403 respectively disposed on the connecting rods 402, and metering plates 404 connected to the positive clamps 403. The two metering plates 404 are arranged opposite to each other and are used to squeeze the paper box to meter the liquid inside the paper box. The output end of the metering cylinder 401 pulls the connecting rods 402 downward, the connecting rods 402 rotate, driving the positive clamps 403 and metering plates 404 to move inward, and the two metering plates 404 squeeze the sides of the paper box to ensure that the side walls of the paper box cannot bend.

[0033] The side clamping mechanism 300 includes a side clamping cylinder 301 and a side clamping plate 302 disposed on the side clamping cylinder 301. The side clamping plate 302 is disposed between two positive clamping seats 403. The side clamping cylinder 301 drives the side clamping plate 302 to clamp the paper box from the other two sides of the paper box.

[0034] The aseptic carton filling equipment is equipped with an automatic volume control valve, a composite filling pipe 600, and a paper dragging mechanism 700.

[0035] Working principle:

[0036] Liquid material enters the inner tube of the composite filling tube 600 through the automatic flow regulating valve 500. When the paper dragging mechanism 700 pulls the paper tube according to the PLC signal, the upper horizontal sealing plate 201 and the lower horizontal sealing plate 202 open, pulling the paper tube downward.

[0037] Whenever a cardboard box is pulled, the side clamping cylinders 301 on both sides of the side clamping mechanism 300 move inward, causing the side clamping plate 302 to push against the paper tube. At the same time, the metering cylinder 401 moves, causing the connecting rod 402 to push the metering plate 404 on the positive clamping seat 403 against the paper tube. Simultaneously, the sealing mechanism inside the horizontal sealing plate 201 squeezes and seals the opening at the top of the cardboard box, squeezing out excess liquid upwards to meter it.

[0038] A cutting mechanism is provided on the inner side of the horizontal sealing plate, which is used to cut the seal of the cardboard box.

[0039] When the paper-driving mechanism 700 drags the paper tube again according to the PLC signal, the horizontal sealing cylinder 205 returns to its original position, the horizontal sealing lower plate 202 opens downward through the first guide bracket 203 and the second guide bracket 204, the paper tube moves downward, the quantitative cylinder 401 returns to its original position, and the quantitative plate 404 on the positive clamp 403 is retracted through the connecting rod 402. The cutting mechanism inside the horizontal sealing lower plate 202 cuts the seal of the paper box, completing one action. The above actions are repeated for production.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
