Description

[0002] Liquid packaging bags are a common packaging form, widely used in the fields of food, beverages, cosmetics, medicine, etc. In the production and filling process of liquid packaging bags, it is crucial to accurately, efficiently and hygienically fill the liquid into the packaging bag. Among them, the existing filling equipment for filling liquid packaging bags usually controls the discharge amount through a spray gun on the discharge pipe. As a component for controlling the liquid discharge amount, the spray gun is difficult to clean when conveying viscous liquids, resulting in blockage of the spray hole or residual liquid contaminating the next batch of bagged liquids, which will affect the sanitary safety and production quality of bagging. In order to improve sanitary safety, two transmission rollers will be used to clamp the bag to control the liquid discharge to achieve bagging of the liquid. In this way, when filling the next bag, one of the transmission rollers needs to be removed so that the bag that has been bagged will fall below. In the process of removing and resetting the transmission roller, the liquid will continue to fall into the bag that has been bagged when the transmission roller is separated from the bag, resulting in an increase in the amount of liquid in the bag, which will reduce the accuracy of bagging and affect the quality and accuracy of the product.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] A filling device for filling liquid packaging bags provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0036] Embodiment 1: Combination Figure 1-Figure 4 As shown, a filling device for bag filling of liquid packaging bags provided by the present invention includes a filling machine body 100 as a carrier of the entire device, a material barrel 101 and a guide pipe 103 connected to the material barrel 101 for discharging are provided on the filling machine body 100, a control box 102 is also provided on the filling machine body 100, a sealing machine 104 for sealing the upper and lower sides of the bag body is fixedly installed on the filling machine body 100, and the sealing machine 104 performs edge sealing on the upper and lower sides of the bag body, a quantitative mechanism 200 for controlling the bagging amount is provided on the filling machine body 100 to ensure that the amount of liquid in each packaging bag is accurate, thereby improving the quality and consistency of the product, and an expansion mechanism 300 for opening the bag body is also installed on the filling machine body 100. After the packaging bag is fully opened, the inflow speed and amount of the liquid can be more accurately controlled, so that the filling accuracy is higher and the splashing and waste of the liquid are reduced.

[0037] The quantitative mechanism 200 includes a frame 201 fixed to the filling machine body 100, and a transmission roller a202 and a transmission roller b203 are respectively rotated in the frame 201. An electric telescopic rod 204 for driving the transmission roller b203 to move is installed on the frame 201. The barrel 101 injects liquid into the bag through the guide tube 103, and the bag containing the liquid part falls on the transmission roller a202 and the transmission roller b203. When the bagging is completed, the transmission roller b203 moves away, and the bag containing the liquid falls below. The transmission roller b203 is reset again to block the bag, so that it completes one bagging. The frame 201 is also equipped with an adjustment component 209 for adjusting the liquid delivery surplus. Since liquid will flow into the bag below when the transmission roller b203 is moved away and reset, this part of the liquid can be calculated in advance to avoid excessive injection of liquid. When the bag falls to the bottom, the amount of liquid in the process of moving the transmission roller b203 away and resetting is calculated to ensure the accuracy of bagging. The setting of the adjustment component 209 can be controlled according to the flow rate of different types of liquids, and the flow rate of the liquid in the process of moving the transmission roller b203 away and resetting can be controlled accurately. The flow rate of the liquid is fully included in the calculation during the process of moving the transmission roller b203 away and resetting, ensuring that the amount of liquid in each packaging bag is accurate and improving the filling accuracy.

[0038] Specifically, a motor a207 is fixedly installed on the frame 201, a connecting shaft 206 is fixedly connected to the transmission roller b203, and a spur gear 208 of meshing transmission is mounted on the connecting shaft 206 and the transmission roller a202. When the motor a207 is started, the transmission roller a202 is driven to rotate, and the transmission roller a202 drives the connecting shaft 206 to rotate through the spur gear 208. The transmission roller b203 rotates with the connecting shaft 206, and then the transmission roller a202 and the transmission roller b203 rotate in opposite directions. By clamping the bag with the transmission roller a202 and the transmission roller b203 and rotating them in opposite directions, the flow of the liquid can be effectively controlled, and the liquid can be prevented from continuing to be discharged, thereby ensuring accurate control of the liquid flow rate during the filling process.

[0039] Furthermore, the free end of the electric telescopic rod 204 is fixedly connected to the load-bearing plate 205, and the connecting shaft 206 is installed on the load-bearing plate 205 through a bearing. When the electric telescopic rod 204 is started, its free end can be extended and retracted, and then the transmission roller b203 on the load-bearing plate 205 can be driven to move, and the bag can be clamped and rotated in the opposite direction. The production rhythm can be flexibly adjusted, and the unloading operation can be stopped or delayed according to actual needs, thereby improving the flexibility and adaptability of the production line.

[0040] According to the embodiment, by controlling the timing of liquid feeding, it is possible to ensure that the filling amount of the liquid in each bag is accurate, thereby improving the filling accuracy.

[0041] Embodiment 2: Combination Figure 3-Figure 6As shown, on the basis of the first embodiment, the adjustment component 209 includes a plurality of guide grooves 2093 provided on the transmission roller b203, each guide groove 2093 is provided with a plurality of guide grooves, and the plurality of transmission rollers b203 are annularly distributed on the outer surface of the transmission roller b203. First, the guide grooves 2093 on the transmission roller b203 are in contact with the transmission roller a202, and the liquid penetrates from the guide grooves 2093 to the bottom, and then the transmission roller b203 rotates to move the guide grooves 2093 to the other side, stopping the flow of the liquid, and completing the single liquid bagging. The guide grooves 2093 can perform secondary control of the discharge amount, but the guide grooves The opening of 2093 is not large. If it is used for unloading all the time, it will affect the unloading speed. Therefore, secondary control can only be performed when unloading is about to be completed. Moreover, due to the rotation of the transmission roller b203, the unloading can be quickly blocked to ensure the accuracy of unloading. The size of each group of guide grooves 2093 is different, which is used to adjust the remaining amount for different types of liquids. According to the opening size of the guide groove 2093, it is used for liquids with different flow rates to further improve the accuracy of bagging. The amount of remaining liquid can be flexibly adjusted to meet the flow rate requirements of different types of liquids and improve the adaptability of filling equipment.

[0042] Specifically, a worm gear 2092 is fixedly connected to the end of the connecting shaft 206, and a worm 2091 is rotatably installed on the load-bearing plate 205 and meshes with the worm gear 2092. When conveying different types of liquids, the guide groove 2093 is rotated to rotate the connecting shaft 206 on the worm gear 2092, and then the guide grooves 2093 with different opening sizes on the connecting shaft 206 can be adjusted. Accurately controlling the liquid flow and avoiding liquid waste can improve production efficiency, ensure that the amount of liquid bagged each time is accurate, reduce the scrap rate, and improve production benefits.

[0043] According to the embodiment, by having guide grooves 2093 of different sizes, the amount of remaining liquid can be flexibly adjusted to meet the flow rate requirements of different types of liquids, thereby improving the adaptability of the filling equipment.

[0044] Example 3: Combination Figure 1 , Figure 7 and Figure 8As shown, on the basis of the first embodiment, the expansion mechanism 300 includes a limit strip 304 fixedly connected to the filling machine body 100, and connecting pieces 302 are slidably connected on both sides of the limit strip 304, and limit grooves 303 are provided on the connecting pieces 302. Arc pieces 301 are provided on both sides of the guide tube 103, and U-shaped frames 307 are fixedly connected between the two connecting pieces 302 and the adjacent arc pieces 301, and the bag is put on the two arc pieces 301, and the two side edges of the bag are respectively on the limit grooves 303, and then the bag can be opened, which is convenient for subsequent edge sealing and liquid bagging of the bag. The two arc pieces 301 and the connecting piece 302 can be moved to both sides respectively, and then the spacing can be adjusted according to the size of the bag, which is convenient for liquid bagging of bags of different sizes. By adjusting the spacing, it is ensured that the bag is correctly opened and fixed, which is conducive to the subsequent operation of liquid bagging of the bag and ensures the accuracy of liquid bagging.

[0045] Specifically, a motor b305 is fixedly mounted on the filling machine body 100, and a bidirectional screw rod 306 is fixedly connected to the output end of the motor b305. Two connecting plates 302 are respectively threadedly connected to the two sides of the bidirectional screw rod 306. When the motor b305 is started, the bidirectional screw rod 306 is driven to rotate. The rotation of the bidirectional screw rod 306 causes the two connecting plates 302 to move to the two sides respectively, and the arc-shaped plate 301 moves with the connecting plate 302, thereby being able to adapt to bags of different sizes.

[0046] Furthermore, a limiting sleeve 309 is fixedly connected to the inner wall of the arc-shaped piece 301, and a connecting strip 308 which is slidably connected to the limiting sleeve 309 is fixedly connected to the guide tube 103. The setting of the connecting strip 308 and the limiting sleeve 309 can reduce the load on the U-shaped frame 307 and facilitate the movement of the arc-shaped piece 301, and can adapt to bags of different sizes, thereby improving the versatility and adaptability of the equipment, and can handle liquid bagging of bags of different specifications, thereby increasing the flexibility of the production line.

[0047] According to the embodiments, by accurately adjusting the size, waste can be reduced, production efficiency can be improved, and production costs can be reduced.

[0048] Embodiment 4: Combination Figure 1 and Figure 2 As shown, on the basis of the first embodiment, electric push rods 106 are fixedly mounted on both sides of the filling machine body 100, and the free ends of the electric push rods 106 are fixedly connected with heat sealing strips 107 for sealing the side edges of the bag body.

[0049] Specifically, a guide plate 105 for guiding out finished products is fixedly connected to the filling machine body 100. The guide plate 105 is located below the sealing machine 104. The finished products after liquid bagging fall onto the guide plate 105 and are then guided out, making it convenient for the staff to pack the finished products.

[0050] Through the above embodiments, it can be known that: first check the size of the bag, the motor b305 starts to drive the bidirectional screw 306 to rotate, the bidirectional screw 306 rotates to make the two connecting pieces 302 move to both sides respectively, the arc piece 301 moves with the connecting piece 302, adapting to the size of the bag, the filling machine body 100 runs to drive the bag to be conveyed, the bag is put on the two arc pieces 301, the two sides of the bag are respectively on the limit grooves 303, and then the bag can be opened, the barrel 101 injects the liquid into the bag through the guide pipe 103, and the bag body containing the liquid part falls on the transmission roller a2. 02 and transmission roller b203. When the bagging is completed, the transmission roller b203 moves away, and the bag containing the liquid falls to the bottom. The transmission roller b203 is reset again. The guide groove 2093 on the transmission roller b203 fits with the transmission roller a202 to block the bag. The liquid penetrates from the guide groove 2093 to the bottom. Then the transmission roller b203 rotates to move the guide groove 2093 to the other side, stopping the flow of the liquid and completing a single liquid bagging. The finished product of the liquid bagging falls on the guide plate 105, and then the finished product is unloaded and the staff packs the finished product.
