Description

Technical Field

[0001] The utility model belongs to the technical field of food packaging, and particularly relates to a flow rolling table for food packaging. Background Art

[0002] The mobile roller table in the food packaging process plays a vital role in the food processing and packaging line. In the final stage of food packaging, the mobile roller table is usually used to drive various packaging equipment, such as automatic carton sealing machines, labeling machines, filling machines, etc. The transmission and operation of the roller table can ensure the automatic packaging and sealing of food, improve packaging efficiency and reduce manual operations.

[0003] Food vacuum packaging has become a common technical means for pre-prepared meals. It uses a mobile roller to transport the bagged food to a vacuum chamber for vacuuming. The mobile roller is based on a conveyor belt, with flanges and pressing wires added to the belt. The pressing wire on the flange is used to press the opening of the bagged food for positioning and transportation.

[0004] When the bagged food is evacuated on the mobile roller, it is transported to the vacuum chamber and the opening of the bagged food is heat-sealed. However, there is almost no air flow in the vacuum chamber, and the heat from the heat seal is easily transferred to the pressing wire. Especially for the high-temperature heat-sealed bagged food, the temperature of the pressing wire increases and the heat dissipation is slow. The subsequent manual operation of the pressing wire is easy to burn your hands. For this reason, we propose a mobile roller for food packaging. Utility Model Content

[0005] The utility model aims to provide a mobile rolling table for food packaging, which can separate hot pressed wires, and the staff can push the perlite tube by hand to move the pressed wires while preventing the hands from being burned.

[0006] The technical solutions adopted in this utility are as follows:

[0007] A mobile rolling table for food packaging comprises a conveyor belt, wherein a plurality of flange plates are fixed at intervals on the outer surface of the conveyor belt, wherein the flange plates are all in the shape of right-angled triangular prisms, and pressing wires are arranged above the inclined surfaces of the flange plates, wherein both ends of the pressing wires are bent toward the adjacent flange plates and the two ends are respectively rotatably connected to the two ends of the flange plates, and the positions of the pressing wires on both sides of the flange plates are integrally provided with bending sections, and the outer parts of the bending sections are sleeved with perlite tubes, and the perlite tubes are staggered from the flange plates in the vertical direction. When packaging food, the pressing wires are lifted upward around the two ends of the flange plates to open the interval between the flange plates and the pressing wires, and the pressing wires are placed on the two ends of the flange plates. The openings of several bagged foods are inserted into the interval, and then the pressing wire is lowered to press the openings of the bagged foods. The conveyor belt is started intermittently to send the bagged foods to the bottom of the vacuum chamber. After the vacuum chamber is pressed down and close to the conveyor belt, the bagged foods can be evacuated and heat-sealed at high temperature. Even if the flange plate and the pressing wire are affected by the high-temperature heat sealing and cause the temperature to rise, the perlite tube on the bending section can separate the hotter pressing wire and subsequently press the opening of the bagged food. The staff can pinch the perlite tube on the bending section to push it, and prevent burns while moving the pressing wire, thereby improving the safety of loading and unloading bagged foods.

[0008] The outer side of the perlite tube is bonded with a foam polyurethane plastic bushing, which is staggered from the flange plate in the vertical direction. The foam polyurethane plastic bushing is used as a soft outer sheath layer on the outer side of the perlite tube to further insulate the temperature. The deformation of the foam polyurethane plastic bushing is used for buffering, which fits the hands of the staff more closely, so as to improve the use experience.

[0009] The conveyor belt is fixed with limit strips at the position between two adjacent flange plates, and the limit strips are parallel to the flange plates. The area between the limit strips and the adjacent flange plates is used as the placement area for the bagged food. The limit strips can support the bottom of the bagged food and reduce the inertial slip of the bagged food during movement.

[0010] Torsion springs are fixed at both ends of the flange plate, and the torsion springs are wound around adjacent pressing wires. The ends of the torsion springs away from the flange plate are fixedly connected to the outsides of the adjacent pressing wires. Lifting the high pressure wire upward will compress the torsion spring and loosen the pressing wire. The natural extension of the two torsion springs can twist the pressing wire toward the inclined surface of the flange plate, thereby driving the pressing wire to press the opening of the bagged food.

[0011] The inclined surfaces of the flange plates are all provided with gradient grooves at intervals. After the bagged food is pressed, the opening is partially immersed in the gradient grooves, thereby increasing the friction area and making the opening more firmly pressed.

[0012] A cover is rotatably installed on the outside of the conveyor belt. The distance between the inner side of the cover and the two ends of the conveyor belt is smaller than the height of the wire pressing. The cover is used to shield the rotating shaft of the conveyor belt and reduce the oil volatilized from the rotating shaft to the bagged food. A servo motor is fixed under the cover to drive the entire conveyor belt to rotate.

[0013] The technical effects achieved by this utility model are:

[0014] The utility model discloses a mobile rolling table for food packaging. When packaging food, the pressing wires are lifted upward around the two ends of the flange plate, the gap between the flange plate and the pressing wires is opened, the openings of a number of bagged foods are inserted into the gap, and then the pressing wires are lowered to press the openings of the bagged foods. The conveyor belt is started intermittently to send the bagged foods to the bottom of the vacuum chamber. After the vacuum chamber is pressed down and closely attached to the belt of the conveyor belt, the bagged foods can be evacuated and heat-sealed at high temperature. When the flange plate and the pressing wires are affected by the high-temperature heat sealing and the temperature rises, the perlite tubes on the bent section can separate the hot pressing wires, and subsequently press the openings of the bagged foods. The staff can pinch the perlite tubes on the bent section by hand to push them, and prevent scalding while moving the pressing wires, so as to improve the safety of loading and unloading the bagged foods.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-4As shown, a mobile roller table for food packaging includes a conveyor belt 1, which is controlled by an industrial computer of a food packaging station. A plurality of flange plates 2 are fixed at intervals on the outer surface of the conveyor belt 1, and the flange plates 2 are all in the shape of right-angled triangular prisms. Pressing wires 3 are arranged above the inclined surfaces of the flange plates 2, and both ends of the pressing wires 3 are bent toward the adjacent flange plates 2 and the two ends are respectively rotatably connected to the two ends of the flange plates 2. The positions on both sides of the flange plates 2 on the pressing wires 3 are integrally provided with bending sections 4, and the outer parts of the bending sections 4 are sleeved with perlite tubes 5, and the perlite tubes 5 are staggered from the flange plates 2 in the vertical direction. The conveyor belt 1 is first arranged directly below the vacuum chamber. When packaging food, one end of the conveyor belt 1 is used for loading and the other end is used for unloading, surrounding the flange plates. 2, lift the pressing wire 3 upward at both ends, open the gap between the flange plate 2 and the pressing wire 3, insert the openings of several bagged foods into the gap, then put down the pressing wire 3 to press the openings of the bagged foods, start the conveyor belt 1 intermittently, send the bagged foods to the bottom of the vacuum chamber, and after the vacuum chamber is pressed down and close to the belt of the conveyor belt 1, the bagged foods can be evacuated and heat-sealed at high temperature. In time, the flange plate 2 and the pressing wire 3 are affected by the high-temperature heat sealing and cause the temperature to rise. The perlite tube 5 on the bending section 4 can separate the hot pressing wire 3, and subsequently press the opening of the bagged food. The staff can pinch the perlite tube 5 on the bending section 4 with their hands to push it, and prevent scalding while moving the pressing wire 3, so as to improve the safety of loading and unloading the bagged foods.

[0023] After the pressing wire 3 falls, it can stick to the inclined surface of the flange plate 2. At the same time, the opening of the bagged food also sticks to the inclined surface of the flange plate 2 and extends upward. In this way, when the vacuum chamber is evacuated, the air inside the bagged food can flow upward from the opening to facilitate exhaust.

[0024] like Figure 3 and Figure 4 As shown, the outer side of the perlite tube 5 is bonded with a foam polyurethane plastic bushing 6, and the foam polyurethane plastic bushing 6 is staggered from the flange plate 2 in the vertical direction. The foam polyurethane plastic bushing 6 is used as a soft outer sheath layer on the outer side of the perlite tube 5 to further insulate the temperature. At the same time, the deformation of the foam polyurethane plastic bushing 6 is used for buffering, which better fits the hands of the staff to improve the use experience.

[0025] like Figure 1 and Figure 2 As shown, the conveyor belt 1 is fixed with a limit strip 7 at the position between two adjacent flange plates 2, and the limit strips 7 are parallel to the flange plates 2. The area between the limit strip 7 and the adjacent flange plates 2 is used as the placement area for the bagged food. The limit strip 7 can support the bottom of the bagged food to reduce the inertial slip of the bagged food during movement.

[0026] like Figure 2 and Figure 3As shown, torsion springs 8 are fixed at both ends of the flange plate 2, and the torsion springs 8 are wound around the adjacent pressing wires 3. The ends of the torsion springs 8 away from the flange plate 2 are fixedly connected to the outsides of the adjacent pressing wires 3. Lifting the high pressure wire 3 upward will compress the torsion spring 8 and loosen the pressing wire 3. By utilizing the natural extension of the two torsion springs 8, the pressing wire 3 can be twisted toward the inclined surface of the flange plate 2, thereby driving the pressing wire 3 to press the opening of the bagged food.

[0027] like Figure 1 and Figure 2 As shown, the inclined surface of the flange plate 2 is provided with gradient grooves 9 at intervals. After the bagged food is pressed, the opening is partially immersed in the gradient grooves 9, increasing the friction area and making the opening more securely pressed.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a cover shell 10 is rotatably installed on the outer side of the conveyor belt 1, and the distance between the inner side of the cover shell 10 and the two ends of the conveyor belt 1 is smaller than the height of the wire pressing 3. The cover shell 10 is used to shield the rotating shaft of the conveyor belt 1 to reduce the oil volatilized from the rotating shaft to the bagged food, and a servo motor is fixed under the cover shell 10 to drive the entire conveyor belt 1 to rotate. This technical solution is a prior art and is not shown in the figure.

[0029] The working principle of the utility model is as follows: when packaging food, one end of the conveyor belt 1 is used for loading and the other end is used for unloading. The pressing wire 3 is lifted upward around the two ends of the flange plate 2, the gap between the flange plate 2 and the pressing wire 3 is opened, the openings of several bagged foods are inserted into the gap, and then the pressing wire 3 is lowered to press the openings of the bagged foods. The conveyor belt 1 is started intermittently to send these bagged foods to the bottom of the vacuum chamber. After the vacuum chamber is pressed down and pressed against the belt of the conveyor belt 1, the bagged foods can be evacuated and heat-sealed at high temperature. In time, the flange plate 2 and the pressing wire 3 are affected by the high-temperature heat sealing and cause the temperature to rise, the perlite tube 5 on the bending section 4 can separate the hot pressing wire 3, and subsequently press the opening of the bagged food. The staff can pinch the perlite tube 5 on the bending section 4 by hand to push it, and prevent scalding while moving the pressing wire 3, so as to improve the safety of loading and unloading the bagged food.

[0030] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
