Description

Technical Field

[0001] The present invention relates to the technical field of food packaging machinery, and further to a multi-position synchronous filling device and a filling line system. Background Art

[0002] In the field of food processing, filling and stuffing technology is one of the most common links in the production process. Filling and stuffing machines can achieve higher production efficiency than manual labor, but the traditional filling and stuffing equipment currently used in the industry can usually only realize the filling or stuffing operation of a single material. However, with the rapid growth of market demand for products, the filling mode of a single material can no longer meet the needs of efficient and intensive production. The existing technology has exposed the following significant defects in actual application: when two or more materials need to be filled or stuffed at the same time, manufacturers need to use multiple devices in series to complete the process. Each device requires an independent operator, which leads to an exponential increase in labor costs. The purchase costs, maintenance costs and energy consumption of multiple devices add significantly to the investment pressure of enterprises. In addition, the floor space occupied by the equipment increases linearly with the number of machines. In urban areas with tight industrial land, the proportion of factory space costs is particularly prominent, further weakening the profitability of enterprises. In addition, the collaborative operation of multiple devices can easily lead to process connection errors, reduce overall production efficiency, and cause equipment redundancy, high costs and inefficient operations.

[0003] Therefore, there is an urgent need to develop an integrated equipment with multi-channel independent control capabilities that can simultaneously complete the filling and stuffing of multiple materials to solve the technical problems of high cost, low efficiency and insufficient space utilization in the existing technology. Summary of the Invention

[0055] It should be pointed out that sealing ring grooves and sealing rings are provided at both ends of the valve core 6. Every two three-way channels 62 form a group, and sealing ring grooves and sealing rings are provided between each group to separate different fillings. In addition, the piston power group can use a high-precision gear pump, a plunger pump, or other pump bodies that adjust the flow and pressure of different materials through independent controllers, which are not limited here.

[0056] In one embodiment, the reference Figure 1 and 2 On the basis of the above embodiment, the filling through-hole group includes a discharge hole 33, a feed hole 31 and a rear frustum hole. The discharge hole 33 is opened on the side of the valve body 3 away from the piston power group, and is correspondingly connected to the nozzle component 4. The feed hole 31 is opened on the side of the valve body 3 away from the substrate 1, and is correspondingly connected to the silo component 5. The rear frustum hole is opened on the side of the valve body 3 close to the piston power group, and is correspondingly connected to the piston power group.

Each nozzle bucket 41 forms a precise match with the discharge hole 33 of the valve body 3 to ensure a smooth transition of the filling flow path and reduce resistance. In addition, the nozzle bucket 41 is extended to the operating position through the discharge pipe 44 to ensure that the final discharge position and angle can be flexibly adjusted according to the arrangement of the dough mold, thereby ensuring that the filling is accurately injected into the center of the dough. The preset hole position of the pressure plate 42 is passed through the threaded connection, and the pressure plate 42 is pressed against the end of the valve body 3 to ensure close contact between the nozzle bucket 41 and the valve body 3, thereby preventing filling leakage and enhancing sealing, and also achieving the effect of quick disassembly.

Every two piston rods are connected to the same nut, so that the nut can be driven back and forth by a servo motor 76 to quantitatively drive the two piston power groups 7.

[0075] The specific working principle of the present invention is: when the valve core 6 rotates to the corresponding suction position, the upper hole of the three-way channel 62 of the valve core 6 is connected with the feed hole 31 of the valve body 3, the three-way rear hole of the valve core 6 is connected with the rear frustum hole of the valve body 3, and the three-way lower hole of the valve core 6 is blocked by the inner wall of the valve body 3, so that the filling can all enter the piston power group according to the preset amount. When the valve core 6 rotates the valve driving angle to 90°, the valve core 6 corresponds to the discharge position, the three-way rear hole of the valve core 6 rotates to the bottom of the valve body 3 and is blocked by the inner wall of the valve body 3, the three-way upper hole of the valve core 6 and the lower hole of the valve core 6 become horizontal and are connected with the front and rear holes of the valve body 3, thereby connecting the piston power group with the hopper, so that a certain amount of filling is discharged from the hopper.

[0076] According to another aspect of the present invention, the present invention further provides a filling line system, comprising:

[0077] The conveying device and the multi-position synchronous filling and stuffing device described in any of the above embodiments, the conveying device is used to convey pastries, the multi-position synchronous filling and stuffing device is arranged directly above the conveying device, and the nozzle component faces the conveying device.

[0078] The base plate 1 is fixed on the slides on both sides of the conveying device of the filling line system, and the filling slide pulls the nozzle bucket 41 of this device to complete the action of inserting the cake or filling forward and pulling out the cake backward; the slide is fixed on the synchronous slide of the filling line system, and the synchronous slide pulls the nozzle bucket 41 from the zero point to the left to synchronously track the cake on the conveyor belt, completing the action of inserting the nozzle bucket into the cake for filling and pulling it out while conveying, and then quickly returns to the zero point to the right, and cycles for the next filling cycle to form a complete assembly line operation.

[0079] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention.
