Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a hopper assembly for a reciprocating packaging machine with high discharge efficiency. Background Technology

[0002] During the operation of a reciprocating packaging machine, the hopper assembly is the core component for material conveying and quantitative control. Its discharge efficiency and stability directly affect the packaging speed and accuracy.

[0003] Traditional hopper components have the following problems: 1. For materials that are highly viscous or prone to clumping (such as flour, wet granules, etc.), they are prone to accumulation and bridging in the hopper, resulting in interruption of discharge, requiring manual unblocking, affecting the continuity of packaging, and reducing production efficiency; 2. Traditional feeding devices mostly use simple gates or pneumatic valves, which are difficult to control the discharge amount accurately, and are prone to leakage and jamming during reciprocating motion, resulting in large deviations in packaging weight, which do not meet the requirements of quantitative packaging.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A hopper assembly for a reciprocating packaging machine with high discharge efficiency includes a hopper body 1. A fixing plate 2 is fixedly connected to the upper left and upper right ends of the hopper body 1. An L-shaped connecting plate 3 is fixedly connected to the upper rear end of the hopper body 1 and the upper end of the left fixing plate 2. An anti-blocking device 4 is movably connected to the lower ends of the two L-shaped connecting plates 3. An installation frame 5 is fixedly connected to the outer side of the two fixing plates 2. A front and rear through-limiting groove 6 is opened at the front and rear ends of the installation frame 5. A feeding device 7 is fixedly connected to the lower right end of the installation frame 5.

[0027] In this embodiment, the anti-blocking device 4 includes a first rotary motor 41 and a driven pulley 43. The output end of the first rotary motor 41 is fixedly connected to a driving pulley 42. The driving pulley 42 and the driven pulley 43 are connected to a drive belt 44. The lower end of the driven pulley 43 is fixedly connected to a fixed rod 45. The lower end of the fixed rod 45 is fixedly connected to a coupling 46. The lower end of the coupling 46 is fixedly connected to a movable rod 47. The outer surface of the movable rod 47 is fixedly connected to a spiral conveying blade 48. The lower end of the first rotary motor 41 is fixedly connected to the upper end of the left fixed plate 2. The upper ends of the driving pulley 42 and the driven pulley 43 are movably connected to the inner wall surfaces of the two L-shaped connecting plates 3 through bearings. A gap is left between the outer edge of the spiral conveying blade 48 and the inner wall surface of the hopper body 1, and the pitch of the spiral conveying blade 48 gradually decreases from top to bottom.

[0028] Through the above scheme: when the anti-blocking device 4 is working, the first rotary motor 41 drives the active pulley 42 to rotate, which drives the driven pulley 43 to rotate synchronously via the transmission belt 44. The driven pulley 43 drives the movable rod 47 to rotate through the fixed rod 45 and the coupling 46, so that the spiral conveying blade 48 rotates with the movable rod. The spiral conveying blade 48, whose pitch gradually decreases from top to bottom, pushes the material downward. The gap between its outer edge and the inner wall of the hopper body 1 avoids friction, while breaking up material agglomeration and accumulation, preventing bridging, ensuring continuous material falling, and improving the continuity of discharge.

[0029] In this embodiment, the feeding device 7 includes a second rotary motor 71. The output end of the second rotary motor 71 is fixedly connected to a threaded rod 72 through the mounting frame 5. A threaded loop 73 is threadedly connected to the outer surface of the threaded rod 72. Limiting plates 74 are fixedly connected to both the front and rear parts of the outer surface of the threaded loop 73. A movable plate 75 is fixedly connected to the upper part of the outer surface of the threaded loop 73. A mounting plate 76 is fixedly connected to the upper end of the movable plate 75. A baffle 77 is fixedly connected to the upper end of the mounting plate 76. The left end of the second rotary motor 71 is fixedly connected to the lower right end of the mounting frame 5. The left end of the threaded rod 72 is movably connected to the left inner wall of the mounting frame 5 through a bearing. The two limiting plates 74 are respectively set in two limiting grooves 6. The upper end face of the baffle 77 fits against the lower end face of the hopper body 1, and the length of the baffle 77 is adapted to the width of the lower end discharge port of the hopper body 1.

[0030] Through the above scheme: when the feeding device 7 is working, the second rotary motor 71 drives the threaded rod 72 to rotate, and the threaded loop 73 moves along the threaded rod due to the threaded connection. The limiting plate 74 slides in the limiting groove 6 to limit the rotation of the threaded loop 73 and ensure smooth movement. The threaded loop 73 drives the moving plate 75, the mounting plate 76 and the baffle 77 to move synchronously. The baffle 77 is attached to the lower end of the hopper body 1. The opening and closing size of the discharge port is controlled by horizontal movement to accurately adjust the feeding amount, avoid leakage or jamming, and adapt to quantitative packaging requirements.

[0031] It should be noted that this utility model is a hopper assembly for a reciprocating packaging machine with high discharge efficiency. During use, the material enters from the upper right opening of the hopper body 1 and accumulates above the spiral conveying blades 48. The first rotary motor 41 drives the drive pulley 42, which in turn drives the driven pulley 43 to rotate via the transmission belt 44. This causes the fixed rod 45, coupling 46, movable rod 47, and spiral conveying blades 48 to rotate synchronously. The variable pitch structure of the spiral conveying blades 48, with a larger pitch at the top and a smaller pitch at the bottom, pushes the material downwards, preventing clumping and bridging. The second rotary motor 71 drives the threaded rod 72 to rotate, and the threaded loop 73 moves along the threaded rod. The linear movement is guided by the sliding guide plate 74 within the limit groove 6, ensuring smooth movement. The threaded loop 73 drives the moving plate 75, mounting plate 76, and baffle 77 to move horizontally. By adjusting the overlap between the baffle 77 and the discharge port of the hopper body 1, the feeding amount is precisely controlled. The baffle 77 opens and closes periodically, and the material falls into the packaging station through the discharge port, completing a single feeding. The threaded rod 72 drives the baffle 77 to reciprocate in both forward and reverse directions, realizing continuous quantitative packaging. The anti-blocking device 4 operates continuously to ensure material flowability, and the feeding device 7 adjusts the discharge amount synchronously. The two work together to improve packaging efficiency and accuracy, and are suitable for automated packaging of sticky or easily caking materials.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
