TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic production, specifically is a food vacuum packaging equipment. BACKGROUND

[0002] There is a lot of moisture in the air, and some food is placed in the air for a long time, which is easy to cause oxidation reaction, and then causes the food to mildew and deteriorate, so when packaging some food, vacuum packaging needs to be used to ensure long-term preservation of food.

[0003] When the vacuum packaging machine seals, it is through the heating of the nickel-chromium alloy belt to generate heat and bond the vacuum bag together, but since the packaging bag contains food, the packaging bag will be uneven, which can easily cause the packaging pressing strip and the heating strip to extrude the packaging bag, causing the edge of the packaging bag to wrinkle and bend, and thus resulting in poor sealing effect of the packaging bag. Therefore, a food vacuum packaging equipment is proposed to solve the above problems. UTILITY MODEL CONTENT

[0004] In view of the deficiencies of the prior art, the utility model provides a food vacuum packaging equipment, which has the advantages of good sealing effect and solves the technical problem of easy wrinkling during sealing.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a food vacuum packaging equipment, which comprises a conveying table for placing materials, a plurality of heating strips are uniformly distributed on the conveying table, a vacuum mechanism is arranged above the conveying table and can be lifted, so that the heating strips and the materials are covered when the vacuum mechanism is lowered, a contact piece is movably arranged in the vacuum mechanism, the contact piece extends to the outside of the vacuum mechanism and slides on the conveying table along with the lowering action of the vacuum mechanism.

[0006] Further, two slide rods extending to the outside are rotatably arranged in the vacuum mechanism, the slide rods are symmetrically inclined, so that when the vacuum mechanism is lowered, the slide rods can abut against the conveying table and slide on the conveying table, and a pressing strip is movably connected to the heating strip.

[0007] Further, a motor is further included, and the pressing strip is rotatably connected to the heating strip by the motor.

[0008] Further, the pressing strip is movably arranged on the heating strip by a clamping structure.

[0009] Further, the part of the slide rod abutting against the conveying table is provided with an arc surface structure.

[0010] Compared with the prior art, the technical scheme of the present application has the following advantages:

[0011] The food vacuum packaging equipment, through the rotation setting slide rod, and the inclined setting, make it follow the vacuum mechanism to descend, resist and slide on the material on the conveying table, so as to flatten the wrinkle and bend, and maintain the flat state through the pressing strip.

[0017] The technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0018] Please refer to Fig. 1-2 and Figure 4 A food vacuum packaging equipment in the present application, including the conveying table 1 for placing the material 3, the conveying table 1 is uniformly distributed with several heating strips 2, the conveying table 1 is provided with a vacuum mechanism 4 above by a driving part 41 such as an electric cylinder or an air cylinder, so that the vacuum mechanism 4 covers the heating strip 2 and the material 3 when descending, the abutting part is movably arranged in the vacuum mechanism 4, and the abutting part extends to the outside of the vacuum mechanism 4 and slides on the conveying table 1 with the descending action of the vacuum mechanism 4.

[0019] The device is provided with the abutting part extending to the outside of the vacuum mechanism 4, so that the abutting part abuts the material 3 on the conveying table 1 when the vacuum mechanism 4 descends, and the abutting part changes the motion direction and slides on the material 3 to flatten the wrinkle of the material 3 after abutting the material 3.

[0020] Please refer to Fig. 3, the vacuum mechanism 4 is rotatably provided with two slide rods 42 extending out of the outside, the slide rods

[0021] 42 are symmetrically and obliquely arranged, so that the slide rods 42 can resist and slide on the conveying table 1 when the vacuum mechanism 4 descends, the pressing strip 21 is movably connected on the heating strip 2, further, the part of the slide rods 42 abutting the conveying table 1 is provided with an arc surface structure.

[0022] The device sets the slide rod 42 to be inclined, so that when the vacuum mechanism 4 is lowered, the slide rod 42 contacts the material 3 on the conveying table 1 and slides on the material 3, flattens the folds and wrinkles of the material 3, and maintains the flat state of the material 3 through the locking of the pressing strip 21, preventing the wrinkles of the material 3 from recovering after being flattened. The above design increases the sealing effect and avoids affecting the sealing of the vacuum packaging after the wrinkles are generated. The contact part 421 of the slide rod 42 is set to be arc-shaped to reduce the pressure when contacting the conveying table 1, so that it can slide smoothly and avoid scratches.

[0023] The device sets the pressing strip 21 to be movable, so that the corners of the material 3 can be placed between the pressing strip 21 and the heating strip 2, and the position of the pressing strip 21 is adjusted to limit and maintain the state of the material 3. The position of the locking pressing strip 21 can adopt various embodiments, and the application provides two preferred embodiments.

[0024] Embodiment one

[0025] The pressing strip 21 is rotatably connected to the heating strip 2 by a motor.

[0026] This embodiment sets a motor to control the rotation of the pressing strip 21 and lock the position of the pressing strip 21, which limits the material 3 and maintains the flat state.

[0027] Embodiment two

[0028] The pressing strip 21 is movably arranged on the heating strip 2 by a clamping structure.

[0029] This embodiment sets the pressing strip 21 to be rotatable or slidable on the heating strip 2, reduces the distance between the pressing strip 21 and the heating strip 2 by rotating or sliding downward, and clamps and limits the material 3. The clamping structure is used to lock the position of the pressing strip 21 and maintain the flat state. The clamping structure can be a buckle that clamps the two in the locked state, or a magnet that attracts each other to form a magnetic attraction fit when the pressing strip 21 and the heating strip 2 are close and adhere to each other.
