Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag sealing machines, in particular to a packaging bag sealing machine for food processing. Background Art

[0002] The packaging and sealing of emulsified sauce, fermented bread crumbs, curry and other foods are carried out by using a horizontal automatic packaging machine. Figure 1-2 As shown in the figure, the sealing mechanism in a horizontal bag-feeding automatic packaging machine uses two cylinders to push two heating plates to transfer heat to the packaging material. When the film portion of the packaging material reaches its melting point, the surface plastic begins to soften. At this point, pressure is applied to bond adjacent film layers together.

[0003] Two cylinders push two heating plates to seal the bags, and the two cylinders must work very precisely and synchronously to ensure the consistency and quality of the bag seal. Poor coordination may result in a loose or deformed seal. The use of two cylinders increases the complexity of the system, which may require more control and maintenance, while also increasing the initial investment cost. The two cylinders require more space to install and operate, which may be a problem for compact packaging lines. In addition, there is currently a method of heat-sealing the bags by driving two heating plates through the extension and contraction of the two piston rods of a two-way cylinder. The two piston rods of the two-way cylinder may become unbalanced during extension and contraction, which may cause uneven pressure on the bag from the heating plate, affecting the sealing quality. Since the movement of the piston rod may not be smooth enough, it may affect the temperature transfer of the heating plate, resulting in uneven sealing. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a packaging bag sealing machine for food processing.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A packaging bag sealing machine for food processing, comprising a horizontal automatic packaging machine for feeding bags and a sealing mechanism provided on the horizontal automatic packaging machine. The sealing mechanism comprises a mounting box fixed to a frame of the horizontal automatic packaging machine for feeding bags, a lifting cylinder fixed to the bottom of the mounting box, a connecting rod rotatably connecting a horizontal T-shaped connecting plate and an end of a piston rod of the lifting cylinder, a turnbuckle rotatably connected to the upper and lower ends of the horizontal T-shaped connecting plate, and a transverse support plate.

[0007] When the connecting rod is lifted and lowered by the action of the lifting cylinder, the horizontal T-shaped connecting plate is driven to swing, thereby driving the vertical plate A connected to the basket bolt and the vertical plate B connected to the transverse support plate to move relatively closer or away from each other, and then driving the heating plate A connected to the guide rod A on the vertical plate A and the heating plate B connected to the guide rod B on the vertical plate B to move relatively closer or away from each other, thereby achieving heat-sealing, clamping and sealing of the food packaging bag.

[0008] The movement of the lifting cylinder drives the swing of the connecting rod and horizontal T-shaped connecting plate, thereby controlling the approach or separation of the heating plate to achieve heat-sealing and clamping seals on the packaging bags. This method enables precise control of the bag seal, improving the consistency and quality of the seal. By precisely controlling the approach or separation of the heating plate, the consistency and quality of the seal are ensured, avoiding problems such as loose seals or deformation. This sealing machine automates the sealing process, reducing reliance on operators and improving production efficiency.

[0009] Preferably, a guide sleeve B is provided in the U-shaped opening B on the vertical plate B for guiding the sliding of the guide rod A;

[0010] A guide sleeve A is provided in the U-shaped opening A on the vertical plate A and cooperates with the guide rod B to guide the sliding.

[0011] Preferably, two guide rods A are provided side by side, and two guide rods B are provided side by side, so as to improve the stability of the entire sealing mechanism.

[0012] Preferably, the turnbuckle bolts and the end of the transverse support plate away from the horizontal T-shaped connecting plate are fixedly connected to the vertical plate A and the vertical plate B respectively.

[0013] Preferably, the end of the guide rod A is fixedly connected to the vertical support plate, the vertical support plate is fixedly connected to the fixed seat A, the heating plate A is fixed to the fixed seat A, the end of the guide rod B is fixedly connected to the fixed seat B, and the heating plate B is fixed on the fixed seat B.

[0014] Preferably, the horizontal T-shaped connecting plate is rotatably connected to the installation box via a sleeve thereon.

[0015] The sealing mechanism can flexibly adjust the angle of the horizontal T-shaped connecting plate to meet packaging requirements.

[0016] Preferably, both ends of the guide rod A and the guide rod B are respectively slidably guided through the installation box, and the installation box is respectively fixed with guide sleeves that cooperate with the guide rod A and the guide rod B to guide the sliding.

[0017] Compared with the prior art, the technical effects and advantages of the utility model are:

[0018] This food processing bag sealing machine uses a lifting cylinder to drive a connecting rod, which in turn drives the swing of a horizontal T-shaped connecting plate. The two ends of the horizontal T-shaped connecting plate are connected to vertical plates A and B via transverse support plates and turnbuckle bolts. As the horizontal T-shaped connecting plate swings, it moves vertical plates A and B closer or farther apart, simultaneously moving guide rods A and B accordingly. This controls the distance between heating plates A and B, achieving a heat-sealed, clamped seal on food packaging bags.

[0019] By turning the turnbuckle, the movement distance of vertical plates A and B, as well as the distance between heating plates A and B, can be quickly adjusted. By precisely controlling the movement of the heating plates to stabilize and improve the uniformity of hot pressing, the consistency and quality of the seal can be ensured, avoiding loose or deformed seals. The use of two side-by-side guide rods increases the stability of the sealing mechanism and reduces the risk of downtime due to failure of a single guide rod. The design of the turnbuckle and transverse support plate facilitates the maintenance and replacement of vertical plates A and B. The horizontal T-shaped connecting plate can be rotatably connected to the mounting box via a sleeve, providing flexibility in adjusting the angle of the sealing mechanism to suit packaging requirements.

[0020] The high degree of automation allows for continuous sealing operations, reducing operator dependence and improving production efficiency. Its easy operation eliminates the need for manual intervention, reducing labor costs. The sealer's compact design makes it suitable for compact production environments. Compared to traditional cylinder-driven mechanisms, this sealer is quieter, creating a more comfortable working environment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The following is combined with Figure 3-4 To further explain this application,

[0028] The present application discloses a packaging bag sealing machine for food processing, comprising a horizontal automatic packaging machine 1 for feeding bags and a sealing mechanism 2 provided on the horizontal automatic packaging machine 1. The sealing mechanism 2 comprises a mounting box 4 fixed to a frame 3 of the horizontal automatic packaging machine 1, a lifting cylinder 5 fixed to the bottom of the mounting box 4, a connecting rod 7 rotatably connecting a horizontal T-shaped connecting plate 6 and the end of the piston rod of the lifting cylinder 5, a basket bolt 8 rotatably connected to the upper and lower ends of the horizontal T-shaped connecting plate 6, and a transverse support plate 9.

[0029] When the lifting cylinder 5 is actuated to drive the connecting rod 7 to move up and down, the horizontal T-shaped connecting plate 6 is driven to swing, thereby driving the vertical plate A10 connected to the basket bolt 8 and the vertical plate B11 connected to the transverse support plate 9 to move relatively closer or away from each other, and then driving the heating plate A13 connected to the guide rod A12 on the vertical plate A10 and the heating plate B15 connected to the guide rod B14 on the vertical plate B11 to move relatively closer or away from each other, thereby realizing the heat-sealing, clamping and sealing of the food packaging bag.

[0030] The movement of the lifting cylinder 5 drives the swinging of the connecting rod 7 and the horizontal T-shaped connecting plate 6, thereby controlling the approach or separation of the heating plate to achieve heat-sealing and clamping seals on the packaging bags. This method allows for precise control of the bag seal, improving the consistency and quality of the seal. By precisely controlling the approach or separation of the heating plate, the consistency and quality of the seal are ensured, avoiding problems such as loose or deformed seals. This sealing machine automates the sealing process, reducing reliance on operators and improving production efficiency.

[0031] Compared to sealing mechanisms using two pneumatic cylinders and a bidirectional cylinder, the use of a lifting cylinder 5 and connecting rod 7 mechanism to control the approach or separation of the heating plate allows for more precise motion control, thereby improving sealing accuracy and consistency. The connecting rod 7 and swing mechanism simplify the mechanical structure and reduce the failure rate. The heating plate moves more smoothly, helping to improve heating uniformity and avoid uneven sealing. A higher degree of automation allows for continuous sealing operations, improving production efficiency. The ease of operation eliminates the need for excessive manual intervention, reducing labor costs. This type of sealing machine occupies a relatively small space, making it suitable for compact production environments. The higher the sealing quality, the better the quality of the final product and work efficiency. Compared to mechanical structures driven by pneumatic cylinders, this type of sealing machine is quieter, creating a more favorable working environment.

[0032] A guide sleeve B17 is located within the U-shaped opening B16 on vertical plate B11, which mates with guide rod A12 for sliding guidance. A guide sleeve A19 is located within the U-shaped opening A18 on vertical plate A10, which mates with guide rod B14 for sliding guidance. This ensures the precise movement of guide rods A12 and B14, preventing uneven sealing caused by movement deviation.

[0033] Two guide rods A12 are arranged side by side, and two guide rods B14 are arranged side by side, so as to improve the stability of the entire sealing mechanism 2.

[0034] The ends of the turnbuckle bolts 8 and the transverse support plates 9 away from the horizontal T-shaped connecting plate 6 are fixedly connected to the vertical plates A10 and B11, respectively. This design makes it more convenient to maintain and replace the vertical plates A10 and B11.

[0035] The end of the guide rod A12 is fixedly connected to the vertical support plate 20, which is fixedly connected to the fixed base A21. The heating plate A13 is fixed to the fixed base A21. The end of the guide rod B14 is fixedly connected to the fixed base B22, and the heating plate B15 is fixed to the fixed base B22. This helps improve the quality and consistency of the seal.

[0036] The horizontal T-shaped connecting plate 6 is rotatably connected to the installation box 4 through the sleeve 23 thereon, so that the sealing mechanism 2 can flexibly adjust the angle of the horizontal T-shaped connecting plate 6 to adapt to packaging requirements.

[0037] The ends of the guide rods A12 and B14 are respectively slidably guided through the installation box 4, and the installation box 4 is respectively fixed with guide sleeves 24 that cooperate with the guide rods A12 and B14 to guide the sliding movement. This can improve the stability of the entire sealing mechanism 2.

[0038] In the food processing packaging bag sealing machine, when the lifting cylinder 5 pushes the connecting rod 7 to rise and fall, it drives the horizontal T-shaped connecting plate 6 to swing. The two ends of the horizontal T-shaped connecting plate 6 are respectively connected to the vertical plate A10 and the vertical plate B11 through the horizontal support plate 9 and the basket bolt 8. Therefore, when the horizontal T-shaped connecting plate 6 swings, it will drive the vertical plates A10 and B11 to move relatively closer or away from each other, that is, drive the guide rod A12 or the guide rod B14 to move in the opposite direction, thereby driving the heating plate A13 and the heating plate B15 to move relatively closer or away. When the heating plates A13 and B15 are relatively close to each other, the food packaging bags are hot-pressed and sealed.

[0039] In addition, turning the basket bolt 8 can adjust the distance between the vertical plate A10 and the vertical plate B11 during movement, and can adjust the distance between the heating plate A13 and the heating plate B15. If the hot pressing is unstable and there is still an opening after hot pressing, you can directly turn the basket bolt 8 to adjust the distance between the heating plate A13 and the heating plate B15 to achieve hot pressing stability and improve the uniformity of hot pressing.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
