Description

Technical Field

[0001] The utility model relates to the technical field of pet food processing equipment, in particular to a pet nutrition paste filling machine. Background Art

[0002] Pet nutritional paste is a special pet food, usually used to supplement the nutrients needed by pets, such as vitamins, minerals, amino acids, etc. Pet nutritional paste is usually packaged in the form of a hose, which is a sealed container with pet nutritional paste inside, and the pet nutritional paste is squeezed out by squeezing the opening on the hose.

[0003] There is a problem with traditional pet nutritional paste filling machines during the filling process, that is, the inside of the packaging tube is not vacuumed. Specifically, when filling pet nutritional paste, there is usually a certain amount of air inside the packaging tube, which may lead to the following defects: (1) Oxidation: The nutrients in the pet nutritional paste easily react with oxygen in the air, resulting in oxidation reaction. Oxidation not only reduces the nutritional value, but also may produce unpleasant odors and tastes, affecting the pet's acceptance of the nutritional paste. (2) Contamination: There are microorganisms and bacteria in the air. The air during the filling process may be brought into the packaging tube, causing the pet nutritional paste to be contaminated by bacteria. In addition to affecting product quality and the health of pets, bacterial contamination may also shorten the life of the product. (3) Degassing: There will be a lot of gas in the un-vacuumed pet nutritional paste packaging tube, which may easily cause the product to expand and degas when the pressure changes. Degassing may cause the packaging tube to deform, the product to leak, or even the packaging to rupture, thereby reducing the product quality and service life.

[0004] Based on the above reasons, it is necessary to improve the existing pet nutrition paste filling machine and filling process to eliminate the adverse consequences of residual air inside the packaging tube on product quality. Utility Model Content

[0027] The utility model is further described below in conjunction with the embodiments and drawings.

[0028] In the first embodiment, Figure 1 , 2 As shown, a pet nutritional paste filling machine includes: a material storage tank 1, a sealed container for containing nutritional paste, and an external air source to assist in discharging; a filling component 2, having a filling pipe 201, a filling port 202 formed at the lower end of the filling pipe 201, a filling piston 203 and a driving member 204 at the upper end, and a side wall connected to the material storage tank 1; a feed pipe 3, connecting the material storage tank 1 and the filling component 2; the filling component 2 also has a suction pipe 205, a suction port 206 formed at the lower end of the suction pipe 205, the suction port 206 is concentrically arranged with the filling port 202, and the gap between the suction port 206 and the filling port 202 forms a filling area 207 of the tube mouth of the packaging tube 8; a vacuum pipe 4, connecting the suction pipe 205 and the vacuum pump 5. Usually, the material storage tank 1 is a glass fiber reinforced plastic or steel storage tank. Since the fluidity of the paste is poor, the material storage tank 1 is maintained at a certain pressure by passing clean compressed air to assist in discharging. The driving member 204 can be a starting or linear motor to drive the filling piston 203 to move axially back and forth to achieve the two actions of feeding and filling. A one-way valve can also be set on the feeding pipe 3 to ensure the reliability of filling. In this embodiment, a special suction pipe 205 is set in the filling component 2 to suck the air inside the packaging tube 8 during the filling process of the pet nutritional cream, which can effectively solve the defects caused by the lack of vacuum, ensure the quality and life of the product, and provide a better use experience of the pet nutritional cream.

[0029] In the first embodiment, Figure 2 As shown, the lower end of the filling tube 201 has a closing section 208, and the end of the closing section 208 forms a filling port 202. The closing section 208 has a small diameter, which is convenient for insertion and matching with the tube mouth of the packaging tube 8, and can also achieve more accurate filling.

[0030] In the first embodiment, Figure 2 As shown, the upper end of the suction pipe 205 is connected to the outer wall of the perfusion pipe 201 through thread sealing. Through the fine thread, the suction pipe 205 and the perfusion pipe 201 can be reliably connected and have good sealing performance. At the same time, the suction pipe 205 is easy to disassemble, which is convenient for maintenance and repair of the perfusion pipe 201.

[0031] In the first embodiment, Figure 2As shown, the height position of the suction port 206 is lower than the filling port 202. In this structure, the suction port 206 can play a certain protective role on the suction port 206, avoid collision damage, and also have a certain anti-pollution function.

[0032] In the first embodiment, the inner wall of the suction port 206 is provided with a seal that matches the tube mouth of the packaging tube 8. Generally speaking, the vacuum degree requirement in the packaging tube 8 is not high, that is, the packaging tube 8 can maintain a certain vacuum degree, so the suction port 206 and the packaging tube 8 are not sealed, and the process requirements can be met. For certain specific products, there may be higher process requirements, and in this case, a seal needs to be provided on the inner wall of the suction port 206. However, correspondingly, the packaging tube 8 needs to be provided with a more complex fixing tool to ensure smooth assembly and separation with the suction port 206.

[0033] In the first embodiment, Figure 3 As shown, it is a schematic diagram of the filling process. First, the filling component 2 is in a high position, and the packaging tube 8 on the conveyor line is sent to the bottom of the filling component 2. At the same time, the driving member 204 drives the filling piston 203 to rise, and the filling tube 201 is fed. Then, the filling component 2 moves down driven by the lifting device, so that the filling tube 201 is inserted into (or close to) the tube mouth of the packaging tube 8. Then, the suction tube 205 starts to evacuate under the control of the control module 7 (by controlling the valve on the vacuum tube 4). After a short time, the control module 7 controls the driving member 204 to drive the filling piston 203 to move down, and the filling tube 201 starts to be filled. During the filling process, the vacuum tube 4 always maintains a vacuum state until the filling is completed. Repeat the above process to achieve efficient automatic filling of pet nutritional paste.

[0034] In the second embodiment, Figure 4 As shown, it also includes a compressed air pipe 6, which is connected to the suction pipe 205 and the compressed air source. Clean compressed air is introduced through the compressed air pipe 6 by timing or manual control to clean the filling port 202.

[0035] In the third embodiment, Figure 5 As shown, multiple filling components 2 share a suction chamber 209, and the suction chamber 209 is connected to the vacuum pump 5 through the vacuum tube 4. In this structure, the suction chamber 209 replaces the original multiple suction tubes 205 and multiple vacuum tubes 4, simplifies the filling component 2 mechanism and the gas path of the equipment, and is more suitable for large-scale equipment use.

[0036] Obviously, the above embodiments of the present invention are only examples for explaining the present invention, and are not intended to limit the implementation methods of the present invention. Other obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
