[0003] The inventors discovered in their daily work that when using the heat-sealing equipment, the surface of the heat-sealed area of the tote bag becomes extremely hot after heat sealing. Although workers can collect the heat-sealed tote bags by holding the non-heat-sealed area, they may still be burned due to operational errors, which could potentially lead to safety accidents. Utility Model Content
[0004] The purpose of this invention is to solve the problem that, in actual use, the surface of the heat-sealed area of the tote bag is extremely hot after heat sealing. Although workers can collect the tote bags by holding the non-heat-sealed area, they may still be burned due to operational errors, which could lead to safety accidents. Therefore, a fully automatic tote bag folding and heat sealing device is proposed.

[0006] The effect achieved by the above components is as follows: by setting up a cooling component, when the heat-sealed tote bag is sent out by the guide rubber belt between the two air blowing boxes, the air intake mechanism allows air to enter the two air blowing boxes, and then blows air from the air outlet to the heat-sealed area of the tote bag, thereby achieving the effect of cooling the heat-sealed area of the tote bag as much as possible.
[0007] Preferably, a water box is provided on the front side of the sealing machine body, and an applicator roller is rotatably connected to the inner wall of the water box.
[0008] The effect achieved by the above components is as follows: by setting up water boxes and water inlet mechanisms, the two water boxes are filled with water. When the bag comes into contact with the applicator roller, the bag moves on the applicator roller, causing the applicator roller to rotate, thereby applying the water in the water boxes to both sides of the bag. This, combined with the blower, accelerates water evaporation, removes heat from the heat-sealed area of the bag, and thus assists in cooling.
[0009] Preferably, the upper end of the blower box is fixedly connected to the connector of an external air pump, and the two blower boxes are fixedly connected to a first connecting pipe.

[0014] The effect achieved by the above components is as follows: by setting the positioning plate and the square bar, and with the help of the elastic mechanism, when the tote bag is located between the two coating rollers, the elastic mechanism is in a stretched state, and its reverse force pulls the square bar, so that the coating rollers are in full contact with the tote bag.
[0015] Preferably, one end of the square rod is fixedly connected to a spring, and the other end of the spring is fixed to the positioning plate.
[0016] The effect achieved by the above components is as follows: by setting the positioning plate and the square rod, and with the help of the spring, when the shopping bag is located between the two applicator rollers, the spring is in a stretched state, and its reverse force pulls the square rod, so that the applicator rollers are in full contact with the shopping bag.
[0017] Preferably, the folding mechanism includes a fixed block fixedly connected to the right end of the sealing machine body. The upper end of the fixed block has an inlet, and the front of the fixed block has an outlet. The inner wall of the outlet is slidably connected to a folding plate. The right end of the folding plate is fixedly connected to an installation rod, and a cylinder is fixedly connected between the installation rod and the fixed block.
[0018] The effect achieved by the above components is as follows: after the raw material of the shopping bag enters the feed port on the fixed block, the cylinder is activated, causing the mounting rod to move, which causes the folding plate to push the shopping bag and fold the raw material of the shopping bag in half.
[0019] Preferably, a long plate is fixedly connected to the front of the sealing machine body, and a movable roller is rotatably connected to the front of the long plate. The movable roller, the first mounting roller, the second mounting roller, and the knurling wheel are all driven to rotate by a motor.
[0020] The effect achieved by the above components is as follows: the folded tote bag material is pushed into the space between two moving rollers on the long plate by the cylinder, and the moving rollers are driven by the motor to rotate, so that the tote bag is sent onto the conveyor belt for conveying.
[0021] In summary, the beneficial effects of this utility model are as follows:
[0022] In this invention, by setting a cooling component, when the heat-sealed tote bag is sent out by the guide rubber belt between the two air blowing boxes, the air intake mechanism allows air to enter the two air blowing boxes, and then blows the air out of the air outlet to the heat-sealed area of the tote bag, thereby achieving the effect of cooling the heat-sealed area of the tote bag as much as possible. This solves the problem that after the tote bag is heat-sealed, the surface of the heat-sealed area of the tote bag is very hot. When workers collect the heat-sealed tote bag, although they can collect it by holding the non-heat-sealed area, they may still be burned due to operational errors, which may lead to safety accidents.

[0030] Reference Figure 3As shown, in this embodiment: the cooling component 2 includes an air blowing box 21 fixedly connected to the front of the sealing machine body 1. An air outlet 22 is provided at the lower end of the air blowing box 21. By setting the cooling component 2, when the heat-sealed tote bag is sent out by the guide rubber belt 9 between the two air blowing boxes 21, air is introduced into the two air blowing boxes 21 through the air inlet mechanism, and then blown out through the air outlet 22 to the heat-sealing area of the tote bag, thereby achieving the effect of cooling the heat-sealing area of the tote bag as much as possible. A water box 25 is provided on the front of the sealing machine body 1, and the inner wall of the water box 25 is rotatably connected to a coating... The applicator roller 26, equipped with water tanks 25 and a water inlet mechanism, ensures that both water tanks 25 are filled with water. When the bag comes into contact with the applicator roller 26, the bag moves on the roller, causing it to rotate and spread the water from the water tanks 25 onto both sides of the bag. This, combined with a blower, accelerates water evaporation, removing heat from the heat-sealed area of the bag and aiding in cooling. An external air pump connector 24 is fixedly connected to the upper end of the blower box 21, and a first connecting pipe 23 is fixedly connected between the two blower boxes 21, connecting the air pump and the connector 24. The machine is started, allowing gas to enter the two air boxes 21 via the first connecting pipe 23.

A second connecting pipe 27 is fixedly connected between the two water boxes 25, connecting the water source pipe and the fixed pipe 211. This allows the two water boxes 25 to be filled with water via the second connecting pipe 27. A positioning plate 28 is fixedly connected to the front of the sealing machine body 1. A square rod 29 is slidably inserted into the upper end of the positioning plate 28, and the square rod 29 is fixed to the water box 25. By setting the positioning plate 28 and the square rod 29, the sealing machine... The elastic mechanism is in a stretched state when the tote bag is located between the two applicator rollers 26. Its reverse force pulls the square rod 29, so that the applicator rollers 26 are in full contact with the tote bag. One end of the square rod 29 is fixedly connected to a spring 210, and the other end of the spring 210 is fixed to the positioning plate 28. By setting the positioning plate 28 and the square rod 29, and with the help of the spring 210, when the tote bag is located between the two applicator rollers 26, the spring 210 is in a stretched state, and its reverse force pulls the square rod 29, so that the applicator rollers 26 are in full contact with the tote bag.
[0031] Reference Figure 2As shown in this embodiment: the folding mechanism 10 includes a fixing block 101 fixedly connected to the right end of the sealing machine body 1. The upper end of the fixing block 101 has an inlet 102, and the front of the fixing block 101 has an outlet 3. A folding plate 107 is slidably connected to the inner wall of the outlet 3. An installation rod 106 is fixedly connected to the right end of the folding plate 107. A cylinder 105 is fixedly connected between the installation rod 106 and the fixing block 101. After the raw material for the tote bag enters the inlet 102 on the fixing block 101, the cylinder 105 is activated. The mounting rod 106 moves, causing the folding plate 107 to push the tote bag, folding the tote bag material in half. The front of the sealing machine body 1 is fixedly connected to the long plate 103, and the front of the long plate 103 is rotatably connected to the moving roller 104. The moving roller 104, the first mounting roller 4, the second mounting roller 8, and the knurling wheel 7 are all driven to rotate by a motor. The folded tote bag material is pushed into the long plate 103 between the two moving rollers 104 by the cylinder 105. The moving roller 104 is driven to rotate by a motor, so that the tote bag is sent onto the conveyor belt 5 for conveying.
[0032] Working principle:
[0033] When sealing a tote bag using a heat-sealing equipment: Feeding: The bag is folded in half by the folding mechanism 10, and the sealing area is automatically fed into the heating zone via the conveyor belt 5 on the first mounting roller 4 of the sealing machine body 1 (the sealing machine body 1 can be model HX-232). Heating and melting: The heating element heats the upper and lower heating blocks 6, and the heat is transferred to the film through the sealing belt, causing it to melt and soften. Pressing: Pressure is applied by the knurling wheel 7 to complete the bonding and form a sealing pattern. Shaping and output: The second mounting roller 8... The guide rubber belt 9 delivers the sealed tote bag, thus completing the fully automatic tote bag edge heat sealing. When the tote bag is delivered by the guide rubber belt 9 between the two air blowing boxes 21, the air pump and connector 24 are connected and started, allowing air to enter the two air blowing boxes 21 via the first connecting pipe 23, and then blown out through the air outlet 22 to the tote bag heat-sealing area, thereby maximizing the cooling effect on the heat-sealing area. A water box 25 is installed, connecting the water source pipe and the fixed pipe 211, allowing water to flow through the second connecting pipe 211... 7. The two water tanks 25 are filled with water. When the bag comes into contact with the applicator roller 26, the bag moves on the roller, causing it to rotate. This spreads the water from the water tanks 25 onto both sides of the bag. Combined with a blower, this accelerates water evaporation, carrying away heat from the heat-sealed area of the bag and aiding in cooling. By using a positioning plate 28 and a square rod 29, and with the aid of a spring 210, when the bag is positioned between the two applicator rollers 26, the spring 210 is stretched, and its counterforce pulls the square rod 29, causing the applicator roller 26 to rotate. 6. After the raw material of the tote bag enters the feed port 102 on the fixed block 101, the cylinder 105 (the cylinder 105 model can be an electric cylinder SDA16) is activated to move the mounting rod 106, which causes the folding plate 107 to push the tote bag and fold the raw material of the tote bag in half, so that it is pushed out from the discharge port 3. The folded raw material of the tote bag is pushed by the cylinder 105 into the space between the two moving rollers 104 on the long plate 103. The moving rollers 104 are driven by the motor to rotate, so that the tote bag is sent onto the conveyor belt 5 for conveying.
