[0002] With the development of society, people have higher and higher requirements for seasonings. Due to regional differences, people in different regions like seasonings with different formulas, and some small businesses have developed seasonings that suit local tastes. In order to facilitate sales and storage, they often use sealed packaging bags for storage, and in order to ensure that their own formulas are not leaked, they often turn seasonings into powder. The application of edge sealing of seasoning packaging bags is becoming more and more extensive.

[0003] The existing edge sealing device for seasoning packaging bags has the following problems:

[0004] 1. After the packaging bag is filled, the bag mouth is open. When packaging, the two sides of the packaging bag are not pre-tightened and the hot pressing edge is directly performed, which easily causes the edge of the two sides of the packaging bag to tilt, affecting the edge quality and the appearance of the product;

[0005] 2. After packaging, the material cannot be automatically discharged and needs to be manually fed in and out, which wastes a lot of time and has low production efficiency.

[0006] Therefore, in view of the above problems, an edge sealing device for seasoning packaging is proposed. Utility Model Content

[0030] A rectangular through slot 3 is provided inside the bottom plate 1 and below the U-shaped frame 7, and a belt transmission mechanism is installed inside the rectangular through slot 3;

[0031] A large inverted L-shaped frame 11 is installed above the bottom plate 1 and on one side outside the U-shaped frame 7. An electric telescopic rod 12 is installed through the upper side wall of the large inverted L-shaped frame 11. A shaping frame 13 is connected to the lower end of the electric telescopic rod 12. A fixed heating plate 14 and a movable heating plate 15 are respectively installed on the upper sides of the opposite side walls of the shaping frame 13.

[0032] Through the above structure, when the limiting plate 8 rotates to the outlet side of the U-shaped frame 7, the loaded packaging bag is placed inside the U-shaped frame 7, and the packaging bag is limited by the U-shaped frame 7 and the limiting plate 8 to prevent the packaging bag from tipping over. The edge-sealed packaging bag can be driven to be discharged through the belt conveyor mechanism;

[0033] The upper part of the packaging bag passes through the inner side of the U-shaped frame 7, and the upper part of the packaging bag is shaped by the U-shaped frame 7, so that the two side walls of the packaging bag are close to each other, and the packaging bag passes through the U-shaped frame 7, and the movable heating plate 15 moves and cooperates with the fixed heating plate 14 to seal the upper part of the packaging bag. The specific structure is as follows:

[0034] Combined with Figure 4 As shown, the belt transmission mechanism includes two groups of wheels 4 rotatably installed between the two opposite side walls of a rectangular through slot 3, a transmission belt 5 is sleeved between the outer sides of the two groups of wheels 4, a motor 6 is installed on the outer side of the base plate 1, and the shaft end of the motor 6 is connected to a group of wheels 4.

[0035] Through the above structure, a group of rotating wheels 4 are driven to rotate by the motor 1 6, and the rotating wheels 4 drive the transmission belt 5 and another group of rotating wheels 4 to rotate, and the transmission belt 5 is used to feed the material.

[0036] Combined with Figure 1 and attached Figure 3 As shown, the lower parts of the inner walls on both sides of the shaping frame 13 are inclined surfaces, a supporting frame 16 is installed on the upper side of the shaping frame 13, a plurality of sets of electric telescopic rods 17 are connected between the supporting frame 16 and the movable heating plate 15, and a control switch 18 is installed on the upper side of the large inverted L-shaped frame 11.

[0037] Through the above structure, the lower parts of the inner walls on both sides of the shaping frame 13 are inclined, so that the upper part of the packaging bag is wide when entering and narrow when exiting inside the shaping frame 13, and the upper part of the packaging bag is close to the two side walls relative to each other. The movable heating plate 15 is pushed to move by multiple groups of electric telescopic rods 17, so that the movable heating plate 15 is close to the fixed heating plate 14, and the motor 1 6, the motor 2 10, the electric telescopic rod 1 12 and the electric telescopic rod 2 17 are controlled by the control switch 18.

[0038] Embodiment 2

[0039] Based on Example 1, please refer to the attached Figure 3 The side of the fixed heating plate 14 and the movable heating plate 15 close to each other is a matching wavy structure.

[0040] Through the above structure of the second embodiment, after the two side walls of the packaging bag are hot-melted by the fixed heating plate 14 and the movable heating plate 15 with a corrugated structure, they are extruded and stretched, so that the edge sealing effect of the two side walls of the packaging bag is better.

[0041] The specific usage is as follows:

[0042] The loaded packaging bag is placed inside the U-shaped frame 7. At this time, the limiting plate 8 is located at the opening of the U-shaped frame 7. The packaging bag is limited by the U-shaped frame 7 and the limiting plate 8. The electric telescopic rod 12 is started by the control switch 18. The electric telescopic rod 12 extends downward to drive the shaping frame 13 to move downward, so that the shaping frame 13 is sleeved on the outer side of the upper part of the packaging bag, and the upper parts of the two side walls of the packaging bag are arranged and pressed tightly. The multiple sets of electric telescopic rods 17 are started by the control switch 18. The multiple sets of electric telescopic rods 17 are actuated at the same time to push the mobile heating plate 15 to move toward the fixed heating plate 14. The hot plate 15 and the fixed heating plate 14 clamp the upper part of the two side walls of the packaging bag to perform hot-melt edge sealing on the packaging bag. After the edge sealing is completed, the control switch 18 automatically starts the motor 1 6 and the motor 2 10, and the motor 2 10 drives the limit plate 8 away from the opening of the U-shaped frame 7. The motor 1 6 drives the transmission belt 5 to rotate to move the packaging bag out of the U-shaped frame 7. After the motor 2 10 sets the rotation angle and time, the direction rotates to rotate the limit plate 8 to the opening of the U-shaped frame 7. During this process, the staff can prepare to put the next group of packaging bags into the U-shaped frame 7, which effectively improves the efficiency of edge sealing of the packaging bags.
