Description

Technical Field

[0001] This utility model relates to the field of machinery related to food production, specifically an automatic sealing machine for producing plastic film for packaging cooked meat snacks. Background Technology

[0002] After the cooked meat snacks have been processed, they all need to be packaged with plastic film. Compared with traditional packaging media, plastic film packaging can effectively isolate external bacteria, dust and odors, reduce the risk of food contamination, and form a stable sealing layer to extend the shelf life of food. In addition, most films can withstand high or low temperatures, making them suitable for hot filling or refrigeration needs.

[0003] To facilitate sealing of plastic films during packaging, most food factories now purchase sealing machines for sealing. However, traditional sealing machines are relatively simple and can only seal plastic films of a single size. Furthermore, during the sealing process, the plastic film is prone to tilting or shaking during transport, which can lead to skewed or wrinkled sealing results. Summary of the Invention

[0004] In order to overcome the defects of traditional sealing machines in the sealing process, this utility model proposes an automatic sealing machine for producing plastic film for cooked meat snack packaging.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0006] An automatic sealing machine for producing plastic film for cooked meat snack packaging includes a front base and a rear frame located behind the front base. A conveyor belt is mounted on the front base. A transverse conveying assembly is mounted at the front of the front base, and a pressure-applying assembly adapted to the conveyor belt is connected to the transverse conveying assembly. An L-shaped guide plate is mounted on the right side of the rear frame, and a corresponding sealing belt and sealing assembly are located at the front of the rear frame. The conveyor belt horizontally conveys the main body of the plastic film, allowing the opening of the plastic film to be sealed by the sealing belt and sealing assembly. The pressure-applying assembly securely presses the main body of the plastic film during the sealing process, preventing the film from shifting or rotating. The transverse conveying assembly moves the pressure-applying assembly horizontally along with the plastic film to ensure a compressed state.

[0007] The beneficial effects of this utility model are:

[0008] 1. This utility model can automatically adjust the distance between the front base and the rear frame, thereby meeting the needs of sealing plastic films of different sizes and models at specific positions, and has wide applicability.

[0009] 2. This utility model can perform positioning calibration for the initial placement of plastic film, preventing problems in subsequent sealing caused by unstable placement.

[0010] 3. This utility model can press the main body of the plastic film with a pressure plate and move synchronously with the plastic film, thereby ensuring that the plastic film will not shake during transportation and effectively avoiding the occurrence of sealing tilt and wrinkles.

[0011] 4. The entire spacing adjustment and sealing process is largely automated by machinery, which is relatively convenient to operate and saves manpower. Attached Figure Description

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described more clearly and completely below with reference to the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present utility model and not all of them. Based on this embodiment, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0019] like Figure 1As shown, an automatic sealing machine for producing plastic film for cooked meat snack packaging includes a front base 1 and a rear frame 2 located behind the front base 1. A conveyor belt 3 is mounted on the front base 1. A transverse conveying assembly is installed at the front of the front base 1, and a pressure-applying assembly adapted to the conveyor belt 3 is connected to the transverse conveying assembly. An L-shaped guide plate is installed on the right side of the rear frame 2, and a corresponding sealing belt and sealing assembly are provided at the front of the rear frame 2. The conveyor belt 3 can drive the main body of the plastic film to be horizontally conveyed, allowing the opening of the plastic film to be sealed by the sealing belt and sealing assembly. The pressure-applying assembly ensures that the main body of the plastic film is fixed and pressed tightly during the sealing process, preventing the plastic film from shifting or rotating. The transverse conveying assembly can drive the pressure-applying assembly to be horizontally transported along with the plastic film to ensure a compressed state.

[0020] like Figure 1 As shown, an automatic adjustment component is provided between the rear frame 2 and the front base 1 to adjust the distance between them. When the volume of the plastic film is large or small, the distance between the rear frame 2 and the front base 1 can be adjusted to meet the specific sealing position requirements of the plastic film.

[0021] like Figure 1 and Figure 2 As shown, the transverse transport assembly includes a double guide rail 4 and a motor 5, both mounted on the front base 1; the motor 5 is connected to a lead screw 6; and an L-shaped loading seat 7, which slides on the double guide rail 4, is threaded onto the lead screw 6. The lead screw 6 is mounted on the front base 1 via a bearing housing. This is a conventional design for a lead screw and nut transmission structure, meaning that the L-shaped loading seat 7 moves horizontally by rotating the lead screw 6.

[0022] like Figure 2 As shown, the pressure-applying assembly consists of a spring 8 mounted on an L-shaped loading seat 7 and a pressure plate 9 connected to the spring 8; the pressure plate 9 abuts against the conveyor belt 3. In use, the pressure plate 9 can press the plastic film tightly under the action of the spring force.

[0023] like Figure 2 As shown, the L-shaped loading seat 7 is welded with a single guide rod 10, and the pressure plate 9 is equipped with a guide sleeve 11 that slides with the single guide rod 10. The above is a conventional design of the sliding structure, which ensures the stability of the clamping operation.

[0024] like Figure 2 As shown, the pressure plate 9 has a through groove 9a on its left side, and a vertically sliding push plate 16 is located at the through groove 9a. The function of the push plate 16 is to facilitate manual positioning calibration when placing the plastic film, i.e., when the right end of the main body of the plastic film is in contact with the push plate 16. Furthermore, the push plate 16 ensures that the plastic film moves synchronously with the pressure plate 9.

[0025] like Figure 1As shown, a double guide rod 12 is welded onto the rear frame 2, which slides with the front base 1. The above is a conventional design for a sliding structure.

[0026] like Figure 3 and Figure 4 As shown, the automatic adjustment assembly includes a three-axis cylinder 13 mounted on the rear frame 2 and a lateral drive block 14 connected to the three-axis cylinder 13; the lateral drive block 14 is provided with an inclined groove 14a. That is, the lateral drive block 14 can be driven to move left and right.

[0027] like Figure 4 As shown, a round shaft 15 is welded to the rear end of the front base 1, which slides and is hinged to the inclined groove 14a. The above is a conventional design of the sliding structure, that is, when the lateral drive block 14 moves left and right, the entire front base 1 and the conveyor belt 3 can move back and forth to achieve the effect of adjusting the spacing.

[0028] The specific method of using this utility model is as follows:

[0029] Step 1: Adjust the distance between the front base 1 and the rear frame 2 according to the size of the plastic film and the sealing position. Specifically, the front base 1 and the conveyor belt 3 are moved back and forth by pushing and pulling the lateral drive block 14 through the three-axis cylinder 13.

[0030] Step 2: Place the plastic film with the right end of the main body attached to the push plate 16, and the part that needs to be sealed attached to the guide plate, and let the pressure plate 9 press the plastic film with the main body.

[0031] Step 3: While conveying the plastic film to the left via the conveyor belt 3, the motor 5 drives the lead screw 6 to rotate, causing the pressure plate 9 to move to the left at the same speed as the plastic film, so that the part of the plastic film that needs to be sealed can stably pass through the sealing belt and sealing assembly to complete the sealing.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
