Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment for food packaging, in particular to a food packaging machine with a detection function. Background Art

[0002] Food packaging machine is one of many electromechanical equipments. Food can be packaged well by food packaging machine.

[0003] The patent name disclosed in the prior art with the announcement number "CN210555878U" is "a food packaging machine". Food is packaged in the packaging machine body. Usually, the food needs to be put into the packaging bag, and then the packaging bag is sealed. The packaged food falls from the discharge port into the collection box. Through the downward tilting setting inside the collection box, the food will slide downward by its own weight to prevent it from piling up at one end of the collection box. After all the food is packaged, the collection box is pulled to the right, and the collection box drives the connecting rod and the sliding rod to move to the right. The sliding rod drives the supporting ring to move to the right. The supporting ring has a rightward pressure on the second spring, which compresses the second spring, and the collection box moves to the right until it can rotate. Then the collection box is rotated to the right, and all the food in the collection box can be poured out for collection.

[0004] In the above-mentioned prior art, after the food is packaged, the food will enter the collection box, and the food in the collection box can be poured out for collection later. In this way, if some food is not sealed well during packaging, the food will be spilled during collection, which makes it inconvenient to detect the packaged food that is not sealed well, thus affecting the later collection operation.

[0050] Then, the electric push rod 19 is started, and the output end of the electric push rod 19 drives the hot pressing and cutting mechanism 18 to move downward, so that the hot pressing and cutting mechanism 18 hot presses the packaging sealing paper between the two limit rods 16 to seal the upper surface of the empty box in the corresponding placement groove 8 directly below and cuts it off at the same time, and the reciprocating operation is carried out in this way, so as to perform the packaging operation well;

[0051] See attached Figure 3-5As shown, during the packaging process, when the left conveying roller 2 rotates to drive the conveyor belt 9 to move, the rear end of the left conveying roller 2 drives the rotating rod 5 and the first convex ball 6 to rotate together, so that the first convex ball 6 squeezes the second convex ball 121 directly below, so that the second convex ball 121 is squeezed and drives the connecting rod 12 to move forward, and at this time the return spring 122 is squeezed and stores force, and then the connecting rod 12 pushes the lateral support rod 10 on the rear side forward, and the outer sides of the front and rear ends of the left and right conveying rollers 2 and 3 are nested and slidably connected with moving disks 4, and the two moving disks 4 on the rear side and the two moving disks 4 on the front side are respectively connected by two lateral support rods 10, and the lower parts of the two moving disks 4 on the left side and the lower parts of the two moving disks 4 on the right side are respectively connected by two longitudinal support rods 11, and the outer side of the rear end of the left conveying roller 2 is installed with a rotating rod 5 at equal angles with the center of the left conveying roller 2 as the center, and the first convex ball 6 is fixed on the front side of the outer end of the rotating rod 5, so that through the longitudinal support rod 1 1, the four movable plates 4 move forward at the same time, and then the four movable plates 4 cooperate with each other to drive the conveyor belt 9 to move forward. When the first convex ball 6 is separated from the second convex ball 121, a connecting rod 12 with a "T"-shaped structure is slidably connected inside the rear side surface of the outer frame assembly 1, and a second convex ball 121 is fixed to the left side of the front end of the connecting rod 12, and a reset spring 122 is nested and connected to the outer side surface of the rear end of the connecting rod 12, and a first convex ball 6 is correspondingly arranged above the second convex ball 121. At this time, the connecting rod 12 can be automatically driven to move backward by the stored force of the reset spring 122, so that the connecting rod 12 drives the transverse support rod 10 and the movable plate 4 to move backward together, and then the four movable plates 4 cooperate with each other to drive the conveyor belt 9 to reciprocate slightly back and forth, so that the food in the empty box in the placement slot 8 can be evenly spread, and the intermittent unloading mechanism 7 is prevented from piling up the food in the middle position of the empty box, so as to facilitate the sealing and packaging operation of the upper part of the empty box.

The length of the toggle rod 13 is greater than the shortest distance between the collecting plate 20 and the right conveying roller 3, and the collecting plate 20 is slidably connected to the inner wall of the right side surface of the outer frame assembly 1; toggle rods 13 are fixed to the outer sides of the front and rear ends of the right conveying roller 3, and the collecting plate 20 is arranged below the toggle rod 13, and the collecting plate 20 forms a reciprocating lifting structure with the outer frame assembly 1 through the toggle rod 13, so that the toggle rod 13 pushes the collecting plate 20 downward, and sliders 201 are installed on the front and rear side surfaces of the collecting plate 20, and the bottom of the slider 201 is fixed with a connecting spring 202, and the front and rear inner walls of the right side of the outer frame assembly 1 are provided with slide grooves 101, and the inside of the slide groove 101 The slider 201 is engaged and slidably connected, and a connecting spring 202 is installed inside the slide groove 101. At this time, the sliders 201 on the front and rear sides of the collecting plate 20 slide in the slide groove 101, and at the same time, the slider 201 squeezes the connecting spring 202 in the slide groove 101, so that the connecting spring 202 starts to accumulate force. When the toggle rod 13 is separated from the collecting plate 20, the collecting plate 20 moves upward by the accumulated force of the connecting spring 202. This is repeated, so that the collecting plate 20 is reciprocated and lifted and shaken, so that the collecting plate 20 can shake the food box packaged above well. If the food box is not sealed well, the food will leak out by shaking at this time, so it is easy for the staff to find it in time, and then the food packaging machine can well detect the packaged food, which can meet different usage requirements;
