Description

An automatic feeding device for vacuum packaging machines

Technical field

The invention relates to the technical field of vacuum packaging machines, and in particular to an automatic feeding device for the vacuum packaging machine.

Background technique

Vacuum packaging has the effect of long storage time and not easy to deteriorate, so it is widely used in the food industry. In the process of vacuum packaging of processed crayfish food, a vacuum packaging machine is needed. During the vacuum packaging process, first separate The upper film and the lower film are formed step by step so that the lower film forms rows of grooves. The grooves of the lower film are used to fill the crayfish. The crayfish are then manually placed into the grooves of the lower film according to a certain weight and quantity. In the tank, the upper film and the lower film are vacuum sealed and packaged in the film laminating machine. However, in the actual production process, manual placement is usually used to place the crayfish into the lower film. , multiple operators are required to manually place the products in the lower film one by one, which makes the labor cost high, and because it is manual operation, the efficiency is also low. In order to solve this problem, an automatic loader of the vacuum packaging machine is needed. Material device.

Contents of the invention

The object of the present invention is to provide an automatic feeding device for a vacuum packaging machine, which has the effect of replacing manual feeding and improving work efficiency.

The above technical objectives of the present invention are achieved through the following technical solutions: an automatic feeding device for a vacuum packaging machine, including a vacuum packaging machine, a conveyor belt is provided at the loading station of the vacuum packaging machine, A material hopper is provided on one side of the conveyor belt. The material hopper is a frame with upper and lower openings. A number of vertical partitions are arranged inside the material hopper. The several partitions divide the interior of the material hopper into a number of cavities. The bottom of the material hopper Two bottom plates are provided, and the two far-away ends of the two bottom plates are respectively hinged with the material hopper. When the two bottom plates are closed, the bottom of the material hopper is closed. The automatic feeding device for the vacuum packaging machine also includes a The control component that adjusts the flipping of the bottom plate to open and close the lower end opening of the material hopper, the first drive component that drives the material hopper to rise and fall, and the second drive component that drives the materials to move horizontally along the feeding direction of the vacuum packaging machine.

By adopting the above technical solution, first, the material hopper is brought closer to the conveyor belt through the action of the driving component one. The conveyor belt transports the crayfish to several cavities of the material hopper. Each cavity corresponds to the concave part of the lower film in the vacuum packaging machine. slot, after the material hopper is loaded with materials, the driving component controls the downward movement of the material hopper so that the material hopper is close to the lower film of the vacuum packaging machine. At the same time, the control component controls the bottom plate at the bottom to open, and the materials in the material hopper will fall to the vacuum In the lower film of the packaging machine, after the material falls, the driving component is reset and the material is received again. The second driving component drives the hopper to move to the next row of grooves of the lower film for unloading. This cycle completes the lowering of the film. loading process.

By adopting the above technical solution, when the crayfish falls into the chamber of the material hopper, the two bottom plates close the opening at the lower end of the material hopper. The cylinder piston rod retracts, driving the connecting rod and material hopper to descend. As the sleeve descends with the connecting rod, the gear on the sleeve rolls on the rack, driving the gear and sleeve to rotate. The rotating sleeve drives the cam to swing. After the cam swings, it contacts and presses down the connecting plate, causing the connecting plate and slider to descend. The spring is stretched by the connecting plate. The descending slider drives the bottom plate to flip through the connecting rod, opening the lower end of the material hopper. The crayfish opens from the lower end of the material hopper. Drop into the lower film on the vacuum packaging machine.

Then the cylinder piston rod extends, driving the connecting rod and material hopper to rise. As the sleeve rises with the connecting rod, the gear on the sleeve rolls on the rack, driving the sleeve to rotate. The rotating sleeve drives the cam to swing. The cam gradually moves away from and separates from the connecting plate. The connecting plate is pulled up by the spring, which drives the slider to rise. The rising slider drives the bottom plate to flip through the connecting rod, closing the lower opening of the material hopper. After rising, the lower opening of the material hopper is closed. status.

As a further arrangement of the present invention, the second driving component includes a screw arranged parallel to the conveying direction of the vacuum packaging machine, a motor driving the screw to rotate, a guide rod arranged parallel to the screw, the bottom of a group of cylinders and the screw The screw nut is fixedly connected, and the bottom of the other group of cylinders is slidingly connected to the guide rod.

By adopting the above technical solution, the motor controls the rotation of the screw, which drives the cylinder to move horizontally, and the cylinder drives the material hopper to move horizontally, so that the material hopper can reach different grooves in the lower film for unloading.

As a further arrangement of the present invention, the conveyor belt includes several groups of conveyor belts one and two. The conveyor belts one and two are arranged horizontally and linearly along the feeding direction of the vacuum packaging machine. The number and position of the conveyor belts one and two are consistent with the material hopper. The number and position of the inner cavities match.

A guide groove is provided on the side of the second conveyor belt away from the first conveyor belt.

By adopting the above technical solution, the material is transported through the first conveyor belt and counted by the counting sensor. After entering the second conveyor belt, it is weighed. After adjusting the required quantity and weight, automatic quantitative transportation can be realized, and the material falls through the guide chute. into the material hopper.

The beneficial effects of the present invention are:

1. During the working process of the vacuum packaging machine, conveyor belt one and conveyor belt two transport crayfish. The crayfish falls into the material hopper through the guide trough, and then controls the cylinder to shrink. During the cylinder contraction process, it will drive the animal hopper to move downward. Make the material hopper close to the lower film groove of the vacuum packaging machine, so that the crayfish can fall into it. At the same time, the contraction of the cylinder will drive the gear on the sleeve to move downward. Due to the meshing of the gear and the rack, the gear rotates. The gear will drive the sleeve to rotate together, and when the sleeve rotates, it will cause the cam on the other side of the sleeve to rotate. When the cam rotates, it will squeeze the connecting plate, causing the connecting plate to move downward, and the connecting plate will drive The slider moves downward along the chute, and the slider moves downward in the chute, which will drive the rotation of the connecting rod, and the connecting rod will drive the two sets of bottom plates to open. That is, when the cylinder shrinks downward, the material hopper is close to the vacuum packaging The machine lowers the film, and at the same time the bottom plate at the bottom of the material hopper opens to realize unloading. When the cylinder extends upward, the material hopper moves away from the vacuum packaging machine and closes the film, close to the conveyor belt. At the same time, the bottom plate at the bottom of the material hopper closes, and the material hopper can be loaded.

2. The materials are transported through the conveyor belt 1, and the counting sensor counts them. After entering the conveyor belt 2, they are weighed. After adjusting the required quantity and weight, automatic quantitative transportation can be realized, and the materials fall into the material hopper through the guide chute. .
