Sliced food sucking device

Abstract

The invention discloses a sliced food sucking device and relates to the technical field of food packaging equipment. The sliced food sucking device structurally comprises a sucking head with a containing cavity. Due to the fact that a sliding buffer part is arranged in the containing cavity, the buffer part gets close to a sucking port of the sucking head before food is sucked, in this way, the first slice of food can be tightly attached to the buffer part by moving a quite small distance when food is sucked, side turning of the first slice of food can be prevented, smooth sucking of follow-up food is ensured, collision between the first slice of food and the buffer part is reduced, and then the food breakage probability is reduced. Meanwhile, due to the fact that the buffer part is moved towards the bottom of the containing cavity by the distance of the thickness of at least one slice of food every time the sucking head sucks one slice of food, side turning of follow-up sucked food can be prevented, collision between food can be reduced, and the food breakage probability is further reduced. In the discharge process, the buffer part pushes all food in the sucking head together, and rapid and smooth discharge is achieved.

Description

technical field [0001] The invention relates to the technical field of food packaging equipment, in particular to a sheet food suction device. Background technique [0002] In the process of packaging food, it is generally necessary to grab the food on the production line (such as biscuits and other flakes) and place it in the wrapping paper or box. During the process of grabbing food, due to the The grasping claws of the device directly act on the food, which is likely to cause damage to the food. For this reason, the existing grasping equipment is generally a suction device that generates negative pressure by vacuuming to absorb food in order to solve the above problems.

[0002] In the process of packaging food, it is generally necessary to grab the food on the production line (such as biscuits and other flakes) and place it in the wrapping paper or box. During the process of grabbing food, due to the The grabbing claws of the device directly act on the food, which is easy to cause damage to the food. Therefore, in order to solve the above problems, the existing grabbing equipment is generally a suction device that generates negative pressure by vacuuming to suck the food.

[0003] In the prior art, the suction device generally includes a cylindrical suction head, the chamber in the suction head communicates with the negative pressure device, and the negative pressure device works to draw away the air in the chamber to form a negative pressure in the chamber. The food directly under the suction head is sucked into the storage chamber. In addition, in order to superimpose and absorb multiple foods at one time, the inner wall of the suction head is also provided with a concave channel. The food in the cavity will not block the passage, so that the food behind can also be sucked into the containing cavity. For example, the patent CN104925305A discloses a vacuum grabbing device. Although this vacuum grabbing device can superimpose and absorb multiple pieces of food at one time, due to the The accommodating cavity is deep, and the food has to travel a long distance to reach the bottom of the accommodating cavity, especially for the first inhaled food. There will be a strong collision between the bottom of the containing cavity or between adjacent foods, which will easily cause food damage. In addition, the negative pressure at the opening of the containing cavity is the strongest, so the suction force is also the largest, but because the containing cavity The bottom of the cavity is far away from the opening, and the adsorption force here is not strong, so it is easy to cause the food sucked for the first time to be unable to accommodate the bottom of the cavity, which will also cause difficulty in sucking and picking up the subsequent food.

[0004] In the prior art, after the suction device sucks multiple pieces of food into the suction head, the suction head will move to the wrapping paper or box, and then the negative pressure device stops working, and the multi-piece food falls to the packaging under the action of gravity. For most foods that are not very heavy, the food will often get stuck in the suction head and affect the smooth unloading of the suction device, thereby affecting the entire packaging efficiency
