Description

Technical Field

[0001] This utility model relates to the field of packaging machine feed hopper technology, specifically a packaging machine feed hopper with anti-clogging function. Background Technology

[0002] Powder packaging machines are specialized equipment used for automated packaging of powdered items. Also known as powder packaging machines, they belong to the category of packaging equipment and are widely used in industries such as food, chemicals, pharmaceuticals, and pesticides. They cover the packaging of materials such as milk powder, condiments, veterinary drugs, and feed. This equipment uses microcomputer control to realize functions such as metering, filling, and sealing. It is mainly divided into two categories: automatic back-seal packaging machines and three-side seal screw metering packaging machines.

[0003] Currently, in the packaging of powder materials, most methods use augers to lift the material into the feed hopper, and then the feed hopper is used to feed the powder materials during packaging. To prevent blockage, existing technologies will install a stirring device inside the feed hopper. However, most of these feed hoppers are fixed, which means that the position of the material entering the feed hopper is also fixed. This can result in a phenomenon where one area of ​​the feed hopper has a large amount of material accumulation while other areas have a small amount of material accumulation, making it impossible for the stirring device to mix the material evenly. Utility Model Content

[0004] The purpose of this invention is to provide a packaging machine feed hopper with anti-clogging function, thereby solving the problems mentioned in the background art.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] A packaging machine feed hopper with anti-clogging function includes a conical feed hopper 1 and a feed pipe 5. The feed pipe 5 is located above the conical feed hopper 1. The machine also includes a platform 2. The feed pipe 5 is eccentrically located above the conical feed hopper 1. A circular through groove 15 is provided on the platform 2. The conical feed hopper 1 is coaxially rotatably connected in the circular through groove 15. At least three rotating shafts 6 are evenly rotatably connected to the circular through groove 15. A gear 7 is fixedly connected to each rotating shaft 6. A gear ring 8 is coaxially fixedly connected to the conical feed hopper 1. At least three gears 7 mesh with the gear ring 8.

[0023] Please see Figure 1 and Figure 2 In this embodiment, four gears 7 are set to mesh with the gear ring 8 simultaneously. The gear ring 8 and the conical feed hopper 1 are coaxially arranged in the circular through groove 15. Since the feed pipe 5 is eccentrically arranged above the conical feed hopper 1, the feed pipe 5 remains fixed when the conical feed hopper 1 rotates circumferentially. Therefore, the powder material can be evenly introduced into the conical feed hopper 1 for packaging through the feed pipe 5.

[0024] At least three bases 14 are fixedly connected to the bottom of the platform 2. Each rotating shaft 6 is rotatably connected to each base 14. A drive source 10 is fixedly installed under one of the bases 14 and is connected to one of the rotating shafts 6.

[0025] Please see Figure 3 In this embodiment, the drive source 10 drives one of the rotating shafts 6 to rotate, thereby making the gear 7 on the rotating shaft 6 the driving gear. When the gear 7 rotates, it can drive the conical feed hopper 1 to rotate through the gear ring 8, thereby causing the gear ring 8 to drive the other three gears 7 to rotate. The rotating shaft 6 not connected to the drive source 10 is connected to the base 14 through a deep groove ball bearing, so that the gear 7 can rotate freely with the gear ring 8.

[0026] The conical feed hopper 1 has at least three horizontally reciprocating stirring rods 17 inside, and each stirring rod 17 is connected to a traction assembly between itself and each rotating shaft 6.

[0027] Please see Figure 1 and Figure 4In this embodiment, when the conical feed hopper 1 rotates, it can drive the stirring rod 17 to reciprocate horizontally through the traction component. However, the stirring rod 17 does not rotate with the conical feed hopper 1. Therefore, when the conical feed hopper 1 drives the powder material inside to rotate, the stirring rod 17 can first contact the synchronously rotating powder material and stir it. At the same time, the stirring rod 17 can reciprocate horizontally in a direction perpendicular to the stirring direction to stir the powder material in different areas and further prevent material blockage.

[0028] It should be noted that a cylindrical structure is provided above the conical feed hopper 1, and the deepest point reached by the lower end of the stirring rod 17 is located at the connection between the cylindrical structure and the conical structure on the conical feed hopper 1.

[0029] The traction assembly includes a connecting plate 9, a bracket 16, and a slide 13. The bracket 16 is fixedly connected to the platform 2, the connecting plate 9 is fixedly connected to the bracket 16, the slide 13 is formed on the connecting plate 9, the top end of the stirring rod 17 is slidably connected inside the slide 13, and a connecting rod assembly is connected between the stirring rod 17 and the rotating shaft 6. The connecting rod assembly includes a crankshaft 11 and a rocker arm 12. The crankshaft 11 is coaxially fixedly connected to the top of the rotating shaft 6, the eccentric end of the crankshaft 11 is hinged to one end of the rocker arm 12, and the other end of the rocker arm 12 is fixedly connected to the stirring rod 17.

[0030] Please see Figures 2 to 4 When the rotating shaft 6 rotates, it can drive the crankshaft 11 to rotate synchronously. The crankshaft 11 can drive one end of the swing arm 12 to revolve. Since the overall length of the swing arm 12 is fixed, when one end of the swing arm 12 revolves, the other end of the swing arm 12 drives the stirring rod 17 to move horizontally and reciprocally along the direction of the chute 13, thereby realizing the horizontal reciprocating stirring of the powder material inside the conical feed hopper 1 by the stirring rod 17.

[0031] A support base 4 is coaxially arranged below the platform 2, and a conical feed hopper 1 is slidably connected inside the support base 4. A connecting arm 3 is fixedly connected between the support base 4 and the platform 2.

[0032] Please see Figure 1 and Figure 3 The support seat 4 can limit the conical feed hopper 1 and prevent the gear ring 8 from separating from the gear 7, thereby ensuring the precise meshing between the gear 7 and the gear ring 8. In order to reduce the friction between the support seat 4 and the conical feed hopper 1, an annular guide rail should be provided on the inner wall of the support seat 4, and ball bearings should be embedded on the outer wall of the conical feed hopper 1 so that the conical feed hopper 1 can rotate with low friction.

[0033] The drive source 10 is a motor, which is fixedly mounted on one of the bases 14 by a frame, and the output end of the motor is connected to the rotating shaft 6 on the base 14.

[0034] Please see Figure 3 In this embodiment, the driving source 10 is a motor, which can drive the rotating shaft 6 to rotate. The motor is mounted on a frame, which can reduce the vibration of the motor during operation, thereby facilitating the movement of the rotating shaft 6.

[0035] 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.
