DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The embodiment of the present application discloses a vacuum packaging device for beef slice processing. Figure 1 The packaging bag comprises a machine 1 and a sealing cover 2. A packaging chamber 11 is defined within the machine 1. The sealing cover 2 is located at the top of the machine 1. One side of the sealing cover 2 is hinged to the side of the machine 1. By flipping the sealing cover 2 over, the sealing cover 2 can be turned over to the top surface of the machine 1. The small surface of the sealing cover 2 abuts the top surface of the machine 1. The sealing cover 2 is then fixed, and the packaging chamber 11 forms a sealed space. An exhaust port is defined in the side wall of the packaging chamber 11. The exhaust port can be used to extract air from the packaging chamber 11, creating a vacuum, thereby indirectly extracting the air from the packaging bag.

[0037] Reference Figure 1 and Figure 2 Several brackets 3 are provided on both sides of the machine 1 along the width direction. The brackets 3 are located in the packaging chamber 11. When the packaging bags are vacuum packed, the packaging bags containing beef slices are placed on the brackets 3. Several brackets 3 are distributed along the length direction of the machine 1.

[0038] A mounting plate 31 is installed between several brackets 3 located on the same side. The length of the mounting plate 31 is parallel to the length of the machine 1. The inner wall of the packaging chamber 11, which runs along the length of the machine 1, is provided with first sliding grooves 12, which are arranged vertically. The two ends of the mounting plate 31 slideably connect to the first sliding grooves 12 on either side, allowing the mounting plate 31 to move vertically. The machine 1 is equipped with an adjustment member for adjusting the height of the mounting plate 31. This adjustment member can be used to adjust the height of the mounting plate 31 when packaging bags of different lengths, thereby improving the equipment's applicability.

[0039] The adjustment member is a first transmission screw 311, which is located in one of the first sliding grooves 12. The axis of the first transmission screw 311 is vertically arranged. The lower end of the first transmission screw 311 is rotatably connected to the bottom wall of the first sliding groove 12. The middle portion of the first transmission screw 311 is threadedly threaded through the mounting plate 31. The upper end of one of the first transmission screws 311 is fixedly connected to a first drive motor 312, which is fixedly connected to the upper groove wall of the first sliding groove 12. By rotating the first transmission screw 311, the mounting plate 31 can be moved up and down, thereby adjusting the height of the mounting plate 31.

[0040] Reference Figure 2 and Figure 3 The cross section of the bracket 3 is U-shaped, and the length direction of the bracket 3 is parallel to the length direction of the mounting plate 31. The bracket 3 is fixedly connected to the upper surface of the mounting plate 31. A sliding plate 32 is provided inside the bracket 3. The sliding plate 32 is located inside the bracket 3. Sliding bars 321 are fixedly connected at the four vertices of the sliding plate 32. A second sliding groove 322 for sliding the sliding bar 321 is opened on the side of the bracket 3. The length direction of the second sliding groove 322 is vertically arranged. The sliding bar 321 is slidably connected to the second sliding groove 322 in the vertical direction, so that the sliding plate 32 can slide vertically relative to the bracket 3.

[0041] Bracket 3 is equipped with a clamping assembly 33, which can clamp the packaging bag placed on the sliding plate 32. When the sliding plate 32 slides downward, the clamping assembly 33 clamps the packaging bag filled with beef slices on the sliding plate 32. The clamping assembly 33 includes a clamping rod 332 and a clamping plate 331. Both side walls of the bracket 3 are defined by a first avoidance groove 34, which is arranged vertically along its length.

The upper end of the clamping rod 332 is located within the bracket 3, and the lower end of the clamping rod 332 is hinged to the outer wall of the bracket 3. There are two clamping plates 331, both of which are located in the bracket 3. The side of the clamping plate 331 away from the other clamping plate 331 is fixedly connected to the upper end of the clamping rod 332. By swinging the clamping rod 332, the two clamping plates 331 can be driven to move towards each other, thereby clamping the packaging bag.

[0042] The clamping assembly 33 also includes a first drive rod 333. The upper end of the first drive rod 333 is fixedly connected to the side of the hinged end of the clamping rod 332 away from the free end. The lower end of the first drive rod 333 passes through the first avoidance groove 34 and extends from the inside of the bracket 3. The clamping rod 332 and the first drive rod 333 are arranged in a V-shape, and the V-shaped opening formed faces the sliding plate 32. The edge of the sliding plate 32 abuts the side wall of the first drive rod 333. When the sliding plate 32 slides downward, it forces the two first drive rods 333 to swing away from each other, thereby driving the two clamping plates 331 to move toward each other to clamp the packaging bag.

[0043] To ensure that the clamping plate 331 returns to its original position after the sealed package is removed from the bracket 3, an elastic band 334 is provided between the two first drive rods 333. The two ends of the elastic band 334 are fixedly connected to the lower ends of the first drive rods 333. Furthermore, a third spring 323 is provided on the inner bottom wall of the bracket 3.
