This process must take into account hygiene and safety, metering accuracy, packaging sealing, and production efficiency. Tomato sauce has good fluidity and can be directly poured into cans by gravity or pumping.

[0003] In the conventional process of pouring ketchup into cans, the ketchup in the cans will splash due to its good fluidity, and the ketchup remaining at the nozzle of the filling pipe will also drip, which can easily cause contamination of the conveyor belt and the outer wall of the can. At the same time, when weighing the filled ketchup, the position of the cans moved to the weighing tool is not limited, which will affect the accuracy of the weighing tool in determining the weight of the cans. Summary of the Invention

[0010] A further technical improvement of the present invention is that a first cylinder arranged horizontally is fixedly installed on the inner wall of the outer shell, a receiving box is fixedly installed on the protruding end of the first cylinder, and the receiving box is located directly below the nozzle. A second shift rod is also fixedly installed on the protruding end of the first cylinder, and the position of the second shift rod corresponds to the position of one end of the transmission plate away from the slide groove.

[0011] A further technical improvement of the present invention is that: an injection tooling for conveying sauce is also fixedly installed on the inner wall of the shell, the injection tooling is a prior art, and the output end of the injection tooling is connected to the input end of the square tube through a hose; by controlling the extended end of the first cylinder to shrink from the longest to the shortest, during this process, the extended end of the first cylinder shrinks to half its length, the second lever will move a period of idle travel, the second lever does not contact the transmission plate, the receiving box will be pulled out from under the nozzle to avoid it blocking the descending path of the square tube, and the extended end of the first cylinder shrinks to the shortest The second lever drives the transmission plate to rotate, thereby pulling the first lever and the square tube down, so that the nozzle extends into the can, and then the filling tool is opened to prevent the ketchup in the can from splashing out. After the ketchup reaching the threshold is injected into the can, the extension end of the first cylinder is controlled to be reset to the longest position. Due to the tension of the first tension spring, the transmission plate drives the first lever and the square tube to rise and reset. At the same time, the ketchup dripping from the nozzle is collected by the receiving box, thereby preventing contamination of the conveyor belt and the outer wall of the can.

[0012] A further technical improvement of the present invention is that the centering mechanism includes two support columns fixedly connected to the support plate, the two support columns are respectively located on the front and rear sides of the weighing tooling, a clamping frame is rotatably provided at the top end of the support column, and a roller is rotatably provided at the end of the clamping frame close to the workbench.

After the ketchup reaching the threshold value is injected into the can, the extended end of the first cylinder is controlled to be reset to the longest position. Due to the tension of the first tension spring, the transmission plate drives the first lever and the square tube to rise and reset, and at the same time, the ketchup dripping from the nozzle is collected by the receiving box, thereby preventing pollution to the conveyor belt and the outer wall of the can.

[0018] When the present invention is in use, the cans with lids installed are conveyed to the top of the weighing fixture by the conveyor belt. At this time, the protruding end of the second cylinder is at its longest, and the two clamping frames are pulled over by the second tension spring, so that the two rollers are separated from each other to avoid the two rollers from hindering the movement of the cans. The position of the can is then initially restricted by the two third levers to prevent it from sliding off the top of the weighing fixture due to excessive movement, and the protruding end of the second cylinder is controlled to slowly shrink to the shortest. In this process, the two rollers are first used to provide rolling thrust to the can respectively, and then the two clamping frames are used to clamp the can in the center so that the can is finally at the top center of the weighing fixture. The protruding end of the second cylinder is then controlled to extend to the longest, which not only facilitates the accurate judgment of the weight of the can, but also facilitates the weighing of subsequent cans.

The extended end of the second cylinder 202 is then controlled to slowly retract to its shortest position. During this process, the two rollers 205 are used to provide rolling thrust to the cans respectively, and then the two clamping frames 204 are used to clamp the cans in the center, so that the cans are finally at the top center of the weighing fixture 12.
