Description

Technical Field

[0001] The present application relates to the technical field of hoppers, and in particular to a hopper of a vacuum packaging machine. Background Art

[0002] The fat and vitamins in the pre-suckling pig feed are very easy to oxidize. Traditional pig feed packaging relies on manual weighing and packaging, which not only causes harm to the human body by inhaling dust, but also seriously affects production efficiency by manual operation. Therefore, the feed packaging machine invented by people can complete the packaging of feed. If vacuum packaging is used to isolate the air, the freshness of the feed can be greatly improved.

[0003] For example, a pig feed vacuum packaging machine disclosed in the Chinese patent announcement number (CN206954550U) includes a discharging device, a weighing device, and a bag pressing device; the discharging device includes a silo, and a material outlet and a discharging cover are arranged at the lower end of the silo; a rotating shaft is arranged horizontally at the material outlet, and the rotating shaft is provided with a stirring blade; the weighing device includes a weighing and packaging table and a gravity sensor, and the gravity sensor is connected to the weighing display; a vacuum pump, a vacuum hose and a dust cover are arranged on the frame; the bag pressing device includes a feeding funnel, and the feeding funnel is arranged above the frame and extends downward through the frame; a fixed arm is arranged on the outside of the feeding funnel, and a movable arm is arranged on the inside of the feeding funnel, the fixed arm is fixedly connected to the frame, and the movable arm is movably connected to the frame, a power cylinder is arranged on the fixed arm, and the other end of the power cylinder is hinged to the movable arm, and the feeding funnel is provided with a protrusion; a vibrator is arranged on one side of the feeding funnel. The pig feed vacuum packaging machine of the utility model has a simple structure and a scientific and reasonable design.

[0004] A hopper is required for vacuum packaging of feed, but the current design of the hopper for vacuum packaging has defects, such as inconvenient operation and easy deformation. After the hopper is filled with feed and vacuumed, excess gas will be released through the pressure relief device in the vacuum packaging machine to prevent the vacuumed bagged product from being difficult to remove due to air pressure and deformation. Therefore, a hopper for a vacuum packaging machine is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a hopper for a vacuum packaging machine, which has the advantages of easy operation and easy removal, and solves the problems of defects in the design of the hopper for vacuum packaging, such as inconvenient operation and easy deformation.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a hopper of a vacuum packaging machine, comprising a hopper box, the interior of the hopper box is provided with a material lifting mechanism for supporting and taking materials from the hopper, and the outer side of the hopper box is provided with a moving mechanism for driving the hopper box to feed materials;

[0007] The material lifting mechanism includes two material lifting handles, a connecting plate and a lever assembly. The two material lifting handles are slidably connected to the inside of the hopper box body, the two ends of the connecting plate are fixedly connected to the two material lifting handles respectively, and the lever assembly is arranged on the outside of the connecting plate;

[0008] The lever assembly includes a lifting lever and a rotating shaft. The lever assembly also includes a connecting port opened on the front side of the hopper box body. The rotating shaft is fixed between the front and rear inner walls of the connecting port. A rotating hole is opened on the outer side of the lifting lever, and the lifting lever is rotatably connected to the rotating shaft through the rotating hole.

[0009] By adopting this technical solution, the lifting lever is fixed to the connecting plate, and the rotating shaft is used as the fulcrum of the lever. When extracting materials, you can step on the outside of the hopper box and push the two lifting handles out of the hopper box through the lever principle to lift the material bag out, making it convenient to quickly remove the product from the hopper.

[0010] Furthermore, the lifting handle is U-shaped, and two lifting handles are arranged along the width direction of the hopper box.

[0011] By adopting this technical solution, it is difficult to take the material bag out of the hopper, and the lifting handle is arranged along the width direction of the hopper, so that the lifting device plays a supporting role.

[0012] Furthermore, a flexible diaphragm is fixed to the inner peripheral wall of the connection port, and the flexible diaphragm is bonded to the outer side of the lifting lever.

[0013] By adopting this technical solution, the flexible diaphragm can block the connection port, facilitating the movement of the lever while maintaining the sealing inside the hopper box.

[0014] Furthermore, the moving mechanism includes a base, a pulley, a clamping assembly, a reinforcing rib and a carrying handle. The base is arranged on the outside of the hopper box. The pulleys are four in number and are respectively fixedly connected to the four corners of the bottom surface of the base. The clamping assembly is arranged on the left and right sides of the base to quickly disassemble and move the hopper box. The reinforcing rib is fixedly connected to the bottom surface of the hopper box, and the carrying handle is fixed to the outside of the hopper box.

[0015] By adopting this technical solution, a specially designed base is combined with pulleys to enable rapid transportation when the material weight is relatively heavy.

[0016] Furthermore, the number of the reinforcing ribs is not less than two and they are evenly distributed on the bottom surface of the hopper box body, and the cross-sectional shape of the reinforcing ribs is a rectangle.

[0017] By adopting this technical solution, reinforcing ribs are added at the bottom and around to improve the deformation of the handle during long-term transportation of the hopper.

[0018] Furthermore, the clamping assembly includes an adjusting screw, a clamping plate and a handwheel. The clamping assembly also includes adjusting screw holes opened on the left and right sides of the base, and the adjusting screw is threadedly connected to the base through the adjusting screw holes. One end of the adjusting screw is rotatably connected to the clamping plate, and the other end of the adjusting screw is fixed to the handwheel.

[0019] By adopting this technical solution, the hopper box is placed in the base, and the hand wheel is rotated to drive the adjusting screw to drive the clamping plate to move and clamp the hopper box for rapid disassembly and assembly between the hopper box and the base, so that it can be pushed and moved.

[0020] Furthermore, anti-slip pads are fixed to opposite sides of the clamping plates on the left and right sides.

[0021] By adopting this technical solution, the clamping stability can be maintained and transportation and use are convenient.

[0022] Furthermore, the inner bottom wall of the base is provided with two slide grooves, and guide slide blocks fixed to the bottoms of the two clamping plates slide inside the two slide grooves.

[0023] By adopting this technical solution, the guide slider slides in the slide groove, so that the clamping plate can be kept in horizontal linear motion under the push of the adjusting screw.

[0024] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0025] 1. The hopper of the vacuum packaging machine is provided with a lifting mechanism. The lifting handle, the lever assembly and the connecting plate cooperate with each other. The lifting handle is arranged along the width direction of the hopper, so that the lifting device plays a supporting role. After processing, the two lifting handles are fixedly combined by the connecting plate. At the same time, the lifting lever is fixed to the connecting plate. The rotating shaft is used as the lever fulcrum. When extracting materials, you can step on the outside of the hopper body and push the two lifting handles out of the hopper body through the lever principle, so that the material bag can be lifted out, which is convenient for quickly removing the product from the hopper.

[0026] 2. The hopper of the vacuum packaging machine has a strengthened grip for easy operation. A wheeled base is specially designed for easy movement, so that it can be pushed and moved when the material is heavy. In order to prevent the ribs from cutting the workers' pants and hands during transportation, the ribs are made of a whole square tube. Ribs are added at the bottom and around to improve the deformation of the handle during long-term transportation of the hopper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] See also Figure 1 A hopper of a vacuum packaging machine in this embodiment includes a hopper box body 1, a lifting mechanism 2 for supporting and taking materials from the hopper is arranged inside the hopper box body 1, and a moving mechanism 3 for driving the hopper box body 1 to feed materials is arranged outside the hopper box body 1.

[0033] See also Figure 2 In order to facilitate the use of extracting materials, the material lifting mechanism 2 in this embodiment includes two material lifting handles 21, a connecting plate 22 and a lever assembly 23. The two material lifting handles 21 are slidably connected to the inside of the hopper box 1, and the two ends of the connecting plate 22 are fixedly connected to the two material lifting handles 21 respectively. The lever assembly 23 is arranged on the outside of the connecting plate 22;

[0034] The lever assembly 23 includes a lifting lever 231 and a rotating shaft 232. The lever assembly 23 also includes a connecting port 233 opened on the front side of the hopper box body 1. After processing, the two lifting handles 21 are fixedly combined using the connecting plate 22. At the same time, the lifting lever 231 is hinged to the connecting plate 22, and the rotating shaft 25 is fixed between the front and rear inner walls of the connecting port 233. A rotating hole is opened on the outer side of the lifting lever 231, and the lifting lever 231 is rotatably connected to the rotating shaft 232 through the rotating hole.

[0035] In this embodiment, the lifting handle 21 is U-shaped, and the two lifting handles 21 are arranged along the width direction of the hopper box body 1. The material bag and feed are stored through the hopper box body 1. Due to air pressure and other reasons, after the material is hollowed out, the material bag is deformed, which may cause a large pressure on part of the material bag and the inner wall of the hopper, making it difficult to take the material bag out of the hopper box body 1. The lifting handle 21 is arranged along the width direction of the hopper, so that the lifting device plays a supporting role. A flexible diaphragm 234 is fixed to the inner wall of the connecting port 233. The flexible diaphragm 234 is bonded to the outer side of the lifting lever 231, and the rotating shaft 232 is used as a lever fulcrum. When extracting materials, you can step on the outside of the hopper box body 1 and push the two lifting handles 21 out of the hopper box body 1 through the lever principle, so that the material bag can be lifted out, which is convenient for quickly removing the product from the hopper.

[0036] See also Figure 3 In order to enhance the performance of the hopper, the moving mechanism 3 in this embodiment includes a base 31, a pulley 32, a clamping assembly 33, a reinforcing rib 34 and a carrying handle 35. The base 31 is arranged on the outside of the hopper box body 1. There are four pulleys 32, which are respectively fixedly connected to the four corners of the bottom surface of the base 31. The clamping assembly 33 is arranged on the left and right sides of the base 31 to quickly disassemble and move the hopper box body 1. The reinforcing rib 34 is fixedly connected to the bottom surface of the hopper box body 1, and the carrying handle 35 is fixed to the outside of the hopper box body 1.

[0037] Among them, the clamping assembly 33 includes an adjusting screw 331, a clamping plate 332 and a handwheel 333. The clamping assembly 33 also includes adjusting screw holes opened on the left and right sides of the base 31, and the adjusting screw 331 is threadedly connected to the base 31 through the adjusting screw holes, one end of the adjusting screw 331 is rotatably connected to the clamping plate 332, and the other end of the adjusting screw 331 is fixed to the handwheel 333. In order to facilitate movement, the base 31 is specially designed to cooperate with the pulley 32. When the material weight is relatively large, the hopper box body 1 is placed in the base 31, and the handwheel 333 is rotated to drive the adjusting screw 331 to drive the clamping plate 332 to move and clamp the hopper box body 1 to quickly disassemble and assemble the hopper box body 1 and the base 31 so that it can be pushed and moved.

[0038] In this embodiment, the number of reinforcing ribs 34 is not less than two, and they are evenly distributed on the bottom surface of the hopper box body 1. The cross-sectional shape of the reinforcing rib 34 is rectangular. Anti-slip pads are fixed on the opposite sides of the left and right clamping plates 332. Two slide grooves are provided on the inner bottom wall of the base 31, and guide sliders 334 fixed to the bottom of the two clamping plates 332 are slid inside the two slide grooves. In order to prevent the reinforcing ribs 34 from cutting the workers' pants and hands during transportation, the reinforcing ribs 34 use a whole square tube; reinforcing ribs 34 are added at the bottom and around to improve the deformation of the handle during long-term transportation of the hopper.

[0039] The working principle of the above embodiment is:

[0040] 1. The hopper box 1 is used to store material bags and feed, etc. Due to air pressure and other reasons, after the material is hollowed out, the material bag is deformed, which may cause a large pressure on part of the material bag and the inner wall of the hopper, making it difficult to take the material bag out of the hopper box 1. The lifting handle 21 is arranged along the width direction of the hopper, so that the lifting device plays a supporting role. After processing, the two lifting handles 21 are fixedly combined by the connecting plate 22. At the same time, the lifting lever 231 is hinged to the connecting plate 22, and the rotating shaft 232 is used as a lever fulcrum. When extracting materials, you can step on the outside of the hopper box 1, and use the lever principle to push the two lifting handles 21 out of the hopper box 1, so that the material bag can be lifted out, which is convenient for quickly removing the product from the hopper.

[0041] 2. In order to facilitate operation, the carrying handle 35 is strengthened; in order to facilitate movement, a base 31 is specially designed, and with the pulley 32, when the weight of the material is relatively large, the hopper box 1 is placed in the base 31, and the hand wheel 333 is rotated to drive the adjusting screw 331 to drive the clamping plate 332 to move and clamp the hopper box 1 for rapid disassembly and assembly between the hopper box 1 and the base 31, so that it can be pushed and moved; in order to prevent the reinforcing ribs 34 from cutting the workers' pants and hands during transportation, the reinforcing ribs 34 use a whole square tube; reinforcing ribs 34 are added at the bottom and around to improve the deformation of the handle during long-term transportation of the hopper.
