Description

Technical Field

[0001] The utility model belongs to the field of sauce processing, and particularly relates to a filling valve which is easy to clean. Background Art

[0002] The variety of sauces used as condiments or for direct consumption is growing rapidly, including chili sauce, broad bean paste, peanut butter, sesame paste, jam, beef and red oil hot pot bases, and more. These sauces often require filling machines to bottle or bag them. To address this, fully automatic and semi-automatic filling machines have emerged. These machines are widely used in the food processing industry because they can more conveniently fill granular, slurry-like fluids into specialized containers.

[0003] However, most current filling valves use a bellows sealing structure. After using the filling valve, the inner cavity of the filling valve needs to be cleaned. However, due to the structural characteristics of the bellows, the sauce is easily retained in the gap of the bellows, causing inconvenience in cleaning. Utility Model Content

[0026] In this embodiment, the lifting mechanism 1 can be implemented using the lifting drive mechanism on the existing filling valve, such as a cylinder drive or an electric cylinder drive. At the same time, a corresponding lifting guide mechanism (such as a combination of a guide rod and a guide sleeve) can be provided to guide the vertical movement of the valve core to improve the movement accuracy of the valve core.

[0027] See also Figure 1 The valve core includes an upper valve core 3 and a lower valve core 8, wherein the upper valve core 3 is connected to the lower valve core 8; in this embodiment, a threaded connection structure is adopted between the upper valve core 3 and the lower valve core 8. By setting the valve core into a split structure, that is, the upper valve core 3 and the lower valve core 8, the center position of the diaphragm 5 can be installed and fixed, and at the same time, it can also be ensured that the diaphragm 5 can separate its upper side space and lower side space.

[0028] See also Figure 1The valve core includes an upper valve body 4 and a lower valve body 7, wherein the upper valve body 4 is mounted on the lower valve body 7 by screws; wherein a through hole is provided in the upper valve body 4, and the valve core enters the inner cavity of the valve body from the through hole; wherein the outer diameter of the through hole is larger than the inner diameter of the valve core, so that it can be easily disassembled to realize the subsequent cleaning of the internal structure.

[0029] See also Figure 1 The diaphragm 5 adopts a polyfluoroethylene diaphragm, and the polyfluoroethylene diaphragm has an arc-shaped structure. The outer side of the polyfluoroethylene diaphragm is installed between the upper valve body 4 and the lower valve body 7, and the inner side is installed between the upper valve core 3 and the lower valve core 8; wherein, by adopting the polyfluoroethylene diaphragm 5 with an arc-shaped structure, it can be stretched and compressed when the valve core moves vertically, so that while adapting to the lifting movement of the valve core, structural fatigue and damage will not occur, which is conducive to extending the service life of the polyfluoroethylene diaphragm 5.

[0030] See also Figure 1 The inner diameter of the inner cavity of the valve body gradually decreases along the discharge direction at the discharge port, so that the sauce entering the inner cavity of the valve body will gather at the discharge port; the plugging head 9 cooperates with the discharge port, and the bottom of the plugging head 9 is a concave structure, that is, the bottom of the plugging head 9 is horizontal, and a groove 12 is provided at the bottom of the plugging head 9; by setting the above structure, dripping can be prevented.

[0031] See also Figure 1 The valve body is provided with a discharge chamber 10 below the discharge port, and a reflux port is provided on the side wall of the discharge chamber 10. The reflux port is connected to the reflux device through a reflux channel. The reflux device collects the excess sauce in the discharge chamber 10 through the reflux port and the reflux channel to prevent the residual sauce in the discharge chamber 10 from falling into the loading station 17 below when the sauce jar / bottle leaves the loading station 17.

[0032] Example 2

In this embodiment, since the filling valve of the present invention is provided with 18 filling stations, that is, 18 filling ports, it is equipped with 18 hoses, and the inlet ends of the 18 hoses are connected to the corresponding reflux channels, and the outlet ends are connected to the collecting pipe 15, or connected to the delivery pump through the collecting pipe; wherein, the length of each of the 18 hoses is 190 mm; but considering that there are errors in the processing of the hoses, it is required that the difference between the longest hose and the shortest hose among the 18 hoses is less than or equal to 5 mm.

[0036] See also Figure 2-Figure 4 A foreign body prevention baffle 16 is provided on the outside of the bottom of the valve body. The foreign body prevention baffle 16 is located above the discharge port. The foreign body prevention baffle 16 is set obliquely or horizontally. By setting the above-mentioned foreign body prevention baffle 16, foreign objects above can be prevented from falling into the loading station 17 below.
