Description

Technical Field

[0001] This utility model relates to the field of food packaging bag technology, specifically a mixing device for food packaging bag production. Background Technology

[0002] After adding various additives, plastic packaging can have good ductility under certain temperature and pressure, making it easy to fix into various specifications required for packaging through cooling and molding. In the production process of food packaging bags, mixing equipment for food packaging bag production is usually used.

[0003] However, current mixing devices for food packaging bag production still have the following shortcomings: In the mixing process of food packaging bag production, when the equipment tilts to discharge, it is usually necessary to use a container bag to receive the material for subsequent handling and storage. However, most mixing devices lack bag opening fixing or limiting devices at the discharge port, which forces operators to manually support the bag opening to receive the material. This method is not only cumbersome and labor-intensive, but also easily generates a large amount of dust during the unloading process, causing workers to be exposed to the dust environment for a long time, which poses a risk of respiratory and other health problems, and poses a hidden danger to safe production and occupational health. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mixing device for the production of food packaging bags, which facilitates fixing the bag opening to the wall of the feeding pipe.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for food packaging bag production, comprising a mixing machine body and a feeding pipe connected to the mixing machine body. Mounting blocks are fixedly connected to the annular outer walls on both sides of the feeding pipe. Mounting plates are fixedly connected to the upper surfaces of the two mounting blocks. Sliding members are mounted on the two mounting plates. Sliding plates are mounted on the two sliding members. A base plate is fixedly connected to the lower surface of the two sliding plates. A pressure plate is mounted on the side of the two sliding plates away from the feeding pipe. A second fastening bolt is threaded onto the upper surface of the side of the two pressure plates near the sliding plates. The lower surface of the pressure plate tightly abuts against the upper surface of the base plate. A retaining component is mounted on the upper surface of the mounting plate.

[0006] Furthermore, the retaining assembly consists of two retaining bolts. The upper surfaces of both mounting plates are provided with multiple evenly distributed threaded grooves. The threaded grooves located near the two mounting blocks can extend downward through the two sliding members into the two sliding plates. The threaded grooves on the two mounting blocks and the threaded grooves on the two mounting plates are adapted in shape, size, and position. The threaded outer walls of the threaded grooves on the two sliding plates are threadedly connected to the threaded outer walls of the two retaining bolts. The two retaining bolts can also be fastened within the threaded grooves on the two mounting plates.

[0007] Furthermore, the retaining assembly comprises multiple limiting rods, multiple mounting rings, and multiple telescopic springs. Multiple evenly distributed limiting grooves are perforated on the upper surfaces of both mounting plates. The limiting grooves located near the two mounting blocks can extend downwards through the two sliding members into the two sliding plates. The limiting grooves on the two mounting blocks and the limiting grooves on the two mounting plates are adapted in shape, size, and position. The inner walls of the multiple limiting grooves on the two mounting plates are slidably connected to the outer walls of the multiple limiting rods. The annular outer wall near the upper end of each limiting rod is fixedly connected to the inner walls of the multiple mounting rings. The upper surfaces of the two mounting plates are fixedly connected to the lower ends of the multiple telescopic springs around the periphery of each limiting groove. The upper ends of the multiple telescopic springs are fixedly connected to the lower end surfaces of the multiple mounting rings. The multiple limiting rods can also be slidably connected within the multiple limiting grooves in the two sliding plates and the two sliding members.

[0008] Furthermore, the sliding member is a first T-shaped slider. The two mounting plates have a first T-shaped groove that penetrates the lower surface of the two mounting plates on the side away from the feed tube. The inner walls of the two first T-shaped grooves are slidably connected to the outer walls of the two first T-shaped sliders. The lower ends of the two first T-shaped sliders are fixedly connected to the upper surfaces of the two slide plates.

[0009] Furthermore, each of the two mounting plates has a baffle detachably connected to the side surface away from the feed pipe, and each of the two baffles has a first fastening bolt threaded onto the side surface away from the feed pipe. Each of the two first fastening bolts passes through the two baffles and is fastened to the two mounting plates.

[0010] Furthermore, a second T-shaped groove is provided on the lower surface of each of the two slide plates. The two second T-shaped grooves penetrate one side surface of the two slide plates away from the feed tube. A second T-shaped slider is slidably connected in each of the two second T-shaped grooves. The end of each of the two second T-shaped sliders away from the feed tube is fixedly connected to the side surface of the two pressure plates close to the feed tube. A handle is fixedly connected to the side wall of each of the two pressure plates.

[0011] Furthermore, multiple evenly distributed slots are provided on the upper surfaces of the two base plates where they contact the opening of the container bag, and multiple evenly distributed locking blocks are fixed to the lower surfaces of the two pressure plates where they contact the opening of the container bag.

This utility model, through the coordinated cooperation of a sliding plate, a base plate, a second T-shaped slider, a pressure plate, and a second fastening bolt, constitutes a "pressing device" for fixing the bag opening of a container bag. During operation, simply place the two bag openings on the base plate, then move the pressure plate downwards via the second T-shaped slider, and lock it with the second fastening bolt. This clamps and presses the bag opening against both sides of the feeding tube. This structure achieves bag opening fixation without manual support, which not only reduces the labor intensity of operators but also isolates workers from the feeding process, improving operational safety and ease of operation.

[0014] 2. This utility model achieves adjustable distance between the two sliding plates through the coordinated cooperation of the first T-shaped slider, the sliding plate, and the fixing component. By sliding the sliding plate, the spacing can be flexibly adjusted according to the different sizes of the container bags, which improves the applicability and adaptability of the device. When the container bags are pressed and fixed, the cooperation between the card block and the card slot further enhances the clamping stability and improves the overall fixing effect of the device.

[0026] 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.

[0027] like Figures 1 to 10 As shown, a mixing device for producing food packaging bags includes a mixing machine body 1 and a feeding pipe 2 connected to the mixing machine body 1. Mounting blocks 3 are fixedly connected to the annular outer walls on both sides of the feeding pipe 2. Mounting plates 4 are fixedly connected to the upper surfaces of the two mounting blocks 3. Sliding parts are installed on the two mounting plates 4. Slide plates 9 are installed on the two sliding parts. Base plates 12 are fixedly connected to the lower surfaces of the two slide plates 9. Pressure plates 16 are installed on the side of the two slide plates 9 away from the feeding pipe 2. Second fastening bolts 18 are threadedly connected to the upper surfaces of the two pressure plates 16 near the slide plates 9. The lower surfaces of the pressure plates 16 are tightly abutted against the upper surfaces of the base plates 12. A retaining component is installed on the upper surface of the mounting plates 4.

[0028] like Figures 1 to 10 As shown, in the food packaging bag production mixing device of this utility model, the distance between the two sliding plates 9 is first adjusted by the sliding component and the fixing component to make it more suitable for the specifications of the container bag. Then, the two bag openings of the container bag used to receive the material are laid flat on the upper surface of the base plate 12. Next, the pressure plate 16 is driven to move downward by the second T-shaped slider 15 and locked by the second fastening bolt 18, clamping and pressing the bag openings on both sides of the feeding pipe 2. After the fixing is completed, the feeding operation can begin. The whole process does not require manual support, which not only reduces the labor intensity of the operators, but also realizes the isolation of personnel from the feeding process, improving the safety and convenience of operation.

[0029] like Figures 1 to 4 , Figure 6 and Figure 7As shown, the retaining assembly consists of two retaining bolts 702. The upper surfaces of the two mounting plates 4 are provided with multiple evenly distributed threaded grooves 701. The threaded grooves 701 located near the two mounting blocks 3 can extend downward through the two sliding members into the two sliding plates 9. The threaded grooves 701 on the two mounting blocks 3 and the threaded grooves 701 on the two mounting plates 4 are matched in shape, size and position. The threaded outer wall of the threaded grooves 701 on the two sliding plates 9 is threadedly connected to the threaded outer wall of the two retaining bolts 702. The two retaining bolts 702 can also be located in the threaded grooves 701 on the two mounting plates 4 for bolt fastening.

[0030] Specifically, as the first embodiment of this utility model, by tightening the two fixing bolts 702 into the threaded groove 701, the distance between the two slide plates 9 can be locked after adjustment. This structure makes the position of the slide plates 9 more stable during use, reduces displacement caused by vibration or external force, thereby improving the overall stability of the device when fixing the container bag, and making the unloading operation safer and smoother.

[0031] like Figure 1 , Figure 2 and Figure 10 As shown, the retaining assembly consists of multiple limiting rods 704, multiple mounting rings 705, and multiple telescopic springs 706. Multiple evenly distributed limiting grooves 703 are perforated on the upper surfaces of both mounting plates 4. The limiting grooves 703 located near the two mounting blocks 3 can extend downwards through the two sliding members into the two sliding plates 9. The limiting grooves 703 on the two mounting blocks 3 and the limiting grooves 703 on the two mounting plates 4 are matched in shape, size, and position. The multiple limiting grooves 703 on the two mounting plates 4... The inner walls are slidably connected to the outer walls of multiple limiting rods 704. The annular outer wall near the upper end of each limiting rod 704 is fixedly connected to the inner wall of multiple mounting rings 705. The upper surfaces of the two mounting plates 4 are fixedly connected to the lower ends of multiple telescopic springs 706 on the periphery of each limiting groove 703. The upper ends of multiple telescopic springs 706 are fixedly connected to the lower end surfaces of multiple mounting rings 705. The multiple limiting rods 704 can also be slidably connected within the multiple limiting grooves 703 in the two sliding plates 9 and the two sliding parts.

[0032] Specifically, as the second embodiment of this utility model, when it is necessary to adjust the spacing, first pull the limiting rod 704 upward to release the lock on the slide plate 9, and then drive the slide plate 9 to move through the sliding member to adjust the spacing between the two slide plates 9 to a suitable position. After the adjustment is completed, release the limiting rod 704. Under the elastic action of the telescopic spring 706, the limiting rod 704 is connected to the upper end of the telescopic spring 706 through the mounting ring 705 to achieve automatic rebound and reset, and relock the position of the slide plate 9. The whole operation process is simpler and improves the adjustment efficiency and ease of use.

[0033] It is worth noting that the limiting groove 703 is also provided with protrusions to enhance the limiting effect of the limiting rod 704. At the same time, the outer wall of the limiting rod 704 is also coated with an anti-corrosion coating to extend its service life.

[0034] The first embodiment of this utility model uses a fixing bolt 702 for fixation, which can provide higher locking stability for the device. The second embodiment uses the cooperation of a limiting rod 704, a limiting groove 703 and a telescopic spring 706 to achieve insertion limit and automatic spring reset. Compared with the first embodiment, this method can easily complete the fixation without the need for any additional tools, and the installation process is simpler and faster. At the same time, compared with the fixing bolt 702 in the first embodiment, the limiting rod 704 is coated with an anti-corrosion coating, which has better corrosion resistance and therefore a longer service life.

[0035] In actual production, manufacturers can flexibly choose the most suitable design scheme for production based on actual production needs and circumstances.

[0036] like Figure 3 , Figure 4 and Figure 7 As shown, the sliding component is a first T-shaped slider 6. The two mounting plates 4 are provided with a first T-shaped groove 5 that penetrates the lower surface of the two mounting plates 4 on the side away from the feed tube 2. The inner wall of the two first T-shaped grooves 5 is slidably connected to the outer wall of the two first T-shaped sliders 6. The lower end of the two first T-shaped sliders 6 is fixedly connected to the upper surface of the two slide plates 9.

[0037] Specifically, when it is necessary to adjust the distance between the two slide plates 9, first release the locking of the fixing component, and then use the sliding of the first T-shaped slider 6 in the first T-shaped groove 5 to change the distance between the two slide plates 9 connected to the two first T-shaped sliders 6, so as to adapt to various sizes of packaging bags.

[0038] like Figure 1 and Figure 2 As shown, baffles 10 are detachably connected to the side surfaces of the two mounting plates 4 away from the feed pipe 2. First fastening bolts 11 are threadedly connected to the side surfaces of the two baffles 10 away from the feed pipe 2. The two first fastening bolts 11 pass through the two baffles 10 and are fastened to the bolts inside the two mounting plates 4.

[0039] Specifically, the baffle 10 restricts the first T-shaped slider 6 within the first T-shaped groove 5 to prevent it from moving out of the detachment device. At the same time, it also facilitates the disassembly of the entire pressing device composed of the slide plate 9, making it convenient for maintenance and replacement.

[0040] like Figures 2 to 4 , Figures 5 to 7As shown, the lower surfaces of the two slide plates 9 are provided with second T-shaped grooves 14. The two second T-shaped grooves 14 penetrate one side surface of the two slide plates 9 away from the feed tube 2. The two second T-shaped sliders 15 are slidably connected in the two second T-shaped grooves 14. The ends of the two second T-shaped sliders 15 away from the feed tube 2 are fixedly connected to the side surface of the two pressure plates 16 near the feed tube 2. The side walls of the two pressure plates 16 are fixedly connected with handles 17.

[0041] Specifically, by sliding the second T-shaped slider 15 up and down, holding the handle 17 and pulling it up and down, the pressure plate 16 moves up and down, making it easy to place the bag opening on the base plate 12. When in use, simply move it up, and after it is placed, slide it down and then lock it.

[0042] like Figure 3 , Figure 5 and Figure 9 As shown, multiple evenly distributed slots 13 are provided on the upper surfaces of the two base plates 12 where they contact the opening of the container bag, and multiple evenly distributed locking blocks 8 are fixed to the lower surfaces of the two pressure plates 16 where they contact the opening of the container bag. The multiple locking blocks 8 and the multiple slots 13 can be locked together, and the positions, shapes and sizes of the multiple locking blocks 8 and the multiple slots 13 are all compatible.

[0043] Specifically, when the container bag is pressed and fixed, the snapping action of the snapping block 8 and the snapping groove 13 can press the opening of the container bag more tightly, which enhances the stability of the clamping and improves the overall fixing effect of the device.

[0044] It should be noted that the contact points between the base plate 12, the pressure plate 16 and the bag opening, as well as the contact points between the locking block 8 and the slot 13, are all equipped with soft elastic pads. These pads enhance the clamping and locking effect of the device, reduce damage to the bag opening, and protect the bag. In addition, the outer walls of the first T-shaped slide 5 and the second T-shaped slide 14, as well as the outer walls of the first T-shaped slider 6 and the second T-shaped slider 15, are all equipped with smooth layers. These layers reduce the frictional resistance between the first T-shaped slide 5 and the first T-shaped slider 6, and between the second T-shaped slide 14 and the second T-shaped slider 15, making the sliding process smoother and enhancing the user experience. At the same time, the outer wall of the handle 17 can be equipped with an anti-slip sleeve to increase the frictional resistance between the handle 17 and the hand, reducing the occurrence of slippage and making it more comfortable to hold.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
