Description

Technical Field

[0001] This invention relates to the field of dairy processing technology, and in particular to a general-purpose semi-automatic dairy filling machine. Background Technology

[0002] Dairy products are a diverse range of foods made primarily from milk or dairy products. Their core ingredients come from the milk of mammals such as cows and sheep. Based on processing techniques and product forms, they can be categorized into liquid dairy products (such as milk, yogurt, and dairy beverages), solid dairy products (such as milk powder and cheese), and other dairy products (such as cream and whey powder). Among these, liquid dairy products occupy a significant market share due to their convenient consumption and easy absorption of nutrients, and consumer demand continues to rise.

[0003] Filling is a crucial step in the production and processing of liquid dairy products, and the performance of the filling machine directly affects the production efficiency, packaging accuracy, and quality stability of the product. For example, Chinese literature CN110127580A describes a high-efficiency dairy product filling machine; CN111017854A describes a quantitative filling mechanism for cosmetic filling machines; CN112093754A describes a semi-automatic liquid filling machine for lactic acid bacteria beverages; and CN113184787A describes an automatic weighing filling machine and its operating method. However, these machines can only adapt to single bottle types or fixed-size packaging containers. For different specifications of ordinary bottles, square boxes, and barrels, it is often necessary to change special clamps, adjust core equipment parameters, or even replace the entire filling device. This single adaptability makes it difficult to meet the diversified development needs of the current dairy product market. With consumption upgrading, consumers have put forward more diversified requirements for the packaging forms and capacities of dairy products. In order to enhance market competitiveness, enterprises need to continuously launch products of different specifications and shapes, leading to frequent switching of packaging types during the production process. The limitations of traditional filling machines not only increase equipment investment costs and downtime for adjustments, reducing overall production efficiency, but also may cause fluctuations in filling accuracy due to frequent adjustments, affecting product quality consistency and bringing additional production costs and quality control pressure to enterprises.

The left limiting plate 22 is threaded onto the third threaded rod 23. When changing to a packaging box 3 of other sizes, the second crank 17 is manually turned, which drives the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 drives the rear limiting plate 13 and the front limiting plate 14 to move. The relative movement allows the rear limiting plate 13 and the front limiting plate 14 to limit the front and rear sides of the packaging box 3. The fourth crank 24 is manually turned, which drives the third threaded rod 23 to rotate. The third threaded rod 23 drives the left limiting plate 22 to move, so that the left limiting plate 22 and the right hollow limiting plate 19 limit the left and right sides of the packaging box 3. It can flexibly adapt to dozens of different specifications of packaging containers such as ordinary bottles, square boxes, and barrels, without the need to replace special clamps or the entire set of devices, which greatly reduces the equipment investment cost.

[0024] Furthermore, the feeding assembly includes a second cylinder 25, a pusher frame 26, and a top plate 27. The second cylinder 25 is fixedly installed on the bottom outer wall of the workbench 2, the pusher frame 26 is fixedly installed on the output end of the second cylinder 25, and two sets of the top plate 27 are fixedly installed on the top of the pusher frame 26. The workbench 2 has an opening, and the pusher frame 26 is movably installed in the opening. By controlling the second cylinder 25, the free end of the second cylinder 25 drives the pusher frame 26 and the top plate 27 to move. The pusher frame 26 and the top plate 27 accurately push the packaging box 3 in the material rack to the filling station and push the filled packaging onto the conveyor belt.

[0025] Furthermore, the conveying assembly includes a left side plate 28, a right side plate 29, a motor 30, a drive roller 31, a driven roller 32, and a conveyor belt 33. A discharge port is provided on the front side of the housing 1. The left side plate 28 is fixedly installed on one side of the discharge port, and the right side plate 29 is fixedly installed on the other side of the discharge port. The motor 30 is fixedly installed on the outer wall of one side of the right side plate 29. The drive roller 31 and the driven roller 32 are rotatably installed on the left side plate 28 and the right side plate 29. The conveyor belt 33 is fitted onto the outer walls of the drive roller 31 and the driven roller 32. The output shaft of the motor 30 is fixedly installed on one end of the drive roller 31. When the motor 30 is started, its output shaft drives the drive roller 31 to rotate, enabling the conveyor belt 33 to transport the filled packaging box 3 from inside the housing 1, quickly transferring the finished product and significantly improving overall production efficiency.

[0026] Furthermore, guide rails 18 are fixedly installed on the front and rear inner walls of the chassis 1. The front and rear sides of the right hollow limiting plate 19 are slidably installed on the guide rails 18. A second threaded rod 20 is rotatably installed on the top of the chassis 1. A third crank 21 is fixedly installed on the top of the second threaded rod 20. The top of the right hollow limiting plate 19 is threaded onto the second threaded rod 20. By manually turning the third crank 21, the third crank 21 drives the left limiting plate 22 to rotate. The rotation of the left limiting plate 22 drives the right hollow limiting plate 19 to rise or fall, which can adjust the material rack's discharge size according to the height of the packaging box 3.

[0027] Furthermore, there are two sets of metering pump 4, material extraction pipe 5, hose 6, insertion pipe 7, first cylinder 8, and material rack, which are arranged in parallel front and back. A control panel 35 is fixedly installed on the front outer wall of the machine box 1.

[0028] Furthermore, a baffle 34 is fixedly installed between the left side plate 28 and the right side plate 29, and the bottom of the baffle 34 contacts the top outer wall of the conveyor belt 33.

[0029] Working principle: The packaging box 3 is placed into the material rack. The control panel 35 controls the second cylinder 25, causing the free end of the second cylinder 25 to drive the pusher 26 and the top plate 27 to move. The pusher 26 and the top plate 27 push the packaging box 3 in the material rack to the bottom of the insertion tube 7. The control panel 3 controls the first cylinder 8, causing the free end of the first cylinder 8 to drive the insertion tube 7 to descend, so that the insertion tube 7 is inserted into the bottleneck of the packaging box 3. The metering pump 4 is started. The metering pump 4 draws liquid dairy products through the extraction pipe 5. The liquid dairy products enter the interior of the packaging box 3 in sequence through the extraction pipe 5, the metering pump 4, the hose 6, and the insertion tube 7, realizing filling. As the second cylinder 25, the pusher 26, and the top plate 27 push the packaging box 3, the filled packaging box 3 will be gradually pushed into the top of the conveyor belt 33. The motor 30 is started. The output shaft of the motor 30 drives the drive roller 31 to rotate, so that the conveyor belt 33 can transport the filled packaging box 3 out from the interior of the machine box 1. When replacing the packaging box 3 with another size, manually turning the second crank 17 drives the bidirectional threaded rod 16 to rotate. The rotation of the bidirectional threaded rod 16 causes the rear limiting plate 13 and the front limiting plate 14 to move relative to each other, thus limiting the front and rear sides of the packaging box 3. Manually turning the fourth crank 24 drives the third threaded rod 23 to rotate, thus moving the left limiting plate 22. This causes the left limiting plate 22 and the right hollow limiting plate 19 to limit the left and right sides of the packaging box 3, thus allowing the material rack to move. Suitable for packaging boxes 3 of most sizes, the first crank 12 is manually turned, which drives the first threaded rod 11 to rotate. The rotation of the first threaded rod 11 drives the lifting plate 10, the first cylinder 8, and the insertion tube 7 to rise or fall. The height of the insertion tube 7 and the first cylinder 8 can be adjusted according to the height of the packaging box 3. The third crank 21 is manually turned, which drives the left limit plate 22 to rotate. The rotation of the left limit plate 22 drives the right hollow limit plate 19 to rise or fall. The material discharge size of the material rack can be adjusted according to the height of the packaging box 3.
