Description

Technical Field

[0001] This utility model relates to the field of heat sealing technology for flat bags, and in particular to a heating and sealing mechanism for a flat bag making machine. Background Technology

[0002] Flat-mouth bag making machines are industrial equipment specifically designed for producing flat-mouth packaging bags. They process plastic or non-woven films into bags without handles and with flat openings through heat sealing, cutting, and other processes. They are widely used in clothing, shopping, waste disposal, industrial packaging, and other fields.

[0003] In existing technology, when heat-sealing a flat bag, the flat bag needs to be placed between two heat-sealing plates, and then the heat-sealing plates heat-seal the flat bag. However, the flat bag between the two heat-sealing plates is prone to wrinkles, which affects the heat-sealing quality of the flat bag. Utility Model Content

[0004] This utility model proposes a heating and sealing mechanism for a flat-mouth bag making machine to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heating and sealing mechanism for a flat-mouth bag making machine, comprising a base and an auxiliary device. The base is detachably mounted on the bag making machine with the aid of the auxiliary device, wherein the base provides support for the entire machine. A bracket is mounted on the upper surface of the base, and a cylinder is fixedly connected to one side of the bracket. The first heat-sealing plate is mounted on the output end of the cylinder, and the second heat-sealing plate is mounted on the upper surface of the base. A smoothing device is mounted on one side of the first heat-sealing plate, wherein the smoothing device can smooth the flat bag between the first heat-sealing plate and the second heat-sealing plate.

[0006] The effect achieved by the above components is as follows: when it is necessary to heat seal the flat bag, the worker places the flat bag between the first heat sealing plate and the second heat sealing plate, the smoothing device smooths the flat bag, and then the cylinder on the bracket is opened. The cylinder moves the first heat sealing plate downwards, and finally the first heat sealing plate and the second heat sealing plate heat seal the flat bag.

[0007] Preferably, the smoothing device includes a motor, which is mounted on one side of the first heat-sealing plate via an L-shaped plate. The motor is fixedly connected to a gear via a reducer. Both sides of the gear are provided with toothed plates, and the two gears are symmetrical to each other. The gears mesh with the toothed plates. A smoothing roller is rotatably connected to one side of the toothed plate, and the smoothing roller is located directly below the first heat-sealing plate.

[0008] The effect achieved by the above-mentioned components is as follows: When heat-sealing the flat bag, the operator opens the cylinder on the support, and the cylinder moves the first heat-sealing plate downwards until the smoothing roller touches the flat bag. Then, the operator turns on the motor on the L-shaped plate, and the motor drives the gear to rotate through the reducer. The gear moves the two toothed plates away from each other, and the two smoothing rollers roll above the flat bag, smoothing the flat bag. When the smoothing rollers move to both sides of the second heat-sealing plate, the cylinder is opened again, and the cylinder continues to move the first heat-sealing plate downwards. Finally, the first and second heat-sealing plates heat-seal the flat bag. The smoothing device achieves the effect of smoothing the flat bag, avoiding wrinkles that could lead to unqualified flat bag processing.

[0009] Preferably, a guide plate is fixedly connected to the upper surface of the base, and the guide plate has a triangular cross-section, wherein the guide plate is located directly in front of the second heat-sealing plate.

[0010] The effect achieved by the above-mentioned components is that by setting up a guide plate, the flat bag is guided, making it easier for workers to place the flat bag between the first heat-sealing plate and the second heat-sealing plate.

[0011] Preferably, a slider is fixedly connected to the rear side of the first heat-sealing plate by means of a support plate, and a groove is provided on the toothed plate corresponding to the slider, wherein the slider and the groove are slidably adapted to each other.

[0012] The effect achieved by the above components is that the slider on the support plate moves in the groove of the toothed plate, thereby restricting the direction of movement of the toothed plate and preventing the toothed plate from shaking.

[0013] Preferably, a baffle is fixedly connected to one end of the toothed plate, wherein the baffle is located at the opening of the slide groove.

[0014] The effect achieved by the above components is that by setting the baffle, the maximum displacement of the slider is limited, preventing the slider from moving out of the groove of the toothed plate.

[0015] Preferably, the auxiliary device includes two symmetrical mounting plates, which are respectively fixedly connected to both sides of the base. The surface of the mounting plate is provided with reserved holes, and bolts are provided on the mounting plate through the reserved holes. One end of the bolt is fixedly connected to a washer, wherein the size of the washer is larger than the size of the reserved hole.

[0016] The effect achieved by the above components is as follows: when the base needs to be installed, the staff first moves the base to a suitable position, then moves the bolts, and the bolts pass through the reserved holes of the mounting plate and are inserted into the inside of the bag making machine. Finally, the pad at one end of the bolt abuts against the surface of the mounting plate, thus achieving the effect of fixing the mounting plate. The auxiliary device achieves the effect of installing the mounting plate and the base, making it convenient for the staff to disassemble and repair the heat sealing equipment when it is damaged.

[0017] Preferably, two control blocks are fixedly connected to the surface of the pad, and the two control blocks are arranged in a centrally symmetrical manner.

[0018] The effect achieved by the above components is to increase the contact area between the worker's hand and the pad by setting the control block, thereby making it easier for the worker to rotate the pad and bringing convenience to the worker.

[0019] Preferably, the arc surface of the bolt is fitted with a washer, wherein the washer is a rubber ring.

[0020] The effect achieved by the above components is that the gaskets protect the pads and prevent damage from contact between the pads and the mounting plate.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] When heat-sealing the flat bag, the worker opens the cylinder on the support, which moves the first heat-sealing plate downwards until the smoothing roller touches the flat bag. Then, the worker turns on the motor on the L-shaped plate, which drives the gear to rotate via a reducer. The gear moves the two toothed plates away from each other, and the two smoothing rollers roll above the flat bag, smoothing it out. When the smoothing rollers move to both sides of the second heat-sealing plate, the cylinder is opened again, and the cylinder continues to move the first heat-sealing plate downwards. Finally, the first and second heat-sealing plates heat-seal the flat bag. The smoothing device achieves the effect of smoothing the flat bag, preventing wrinkles and ensuring the flat bag does not become defective. Attached Figure Description

A first heat-sealing plate 4 and a second heat-sealing plate 5 are mounted, with the first heat-sealing plate 4 mounted on the output end of the cylinder 3 and the second heat-sealing plate 5 mounted on the upper surface of the base 1. A smoothing device 7 is mounted on one side of the first heat-sealing plate 4, and the smoothing device 7 can smooth the flat bag between the first heat-sealing plate 4 and the second heat-sealing plate 5. When the flat bag needs to be heat-sealed, the worker places the flat bag between the first heat-sealing plate 4 and the second heat-sealing plate 5, the smoothing device 7 smooths the flat bag, and then the cylinder 3 on the bracket 2 is opened. The cylinder 3 moves the first heat-sealing plate 4 downwards, and finally the first heat-sealing plate 4 and the second heat-sealing plate 5 heat-seal the flat bag.

[0031] Reference Figure 1-6As shown, the smoothing device 7 includes a motor 71, which is mounted on one side of the first heat-sealing plate 4 via an L-shaped plate. The motor 71 is fixedly connected to a gear 72 via a reducer. Both sides of the gear 72 are provided with toothed plates 73. The two gears 72 are symmetrical to each other, and the gear 72 meshes with the toothed plates 73. A smoothing roller 74 is rotatably connected to one side of the toothed plates 73, and the smoothing roller 74 is located directly below the first heat-sealing plate 4. When heat-sealing the flat bag, the worker opens the cylinder 3 on the support 2. The cylinder 3 moves the first heat-sealing plate 4 downwards until the smoothing roller 74 touches the flat bag. Then, the worker turns on the motor 71 on the L-shaped plate. The motor 71 drives the gear 72 to rotate through the reducer. The gear 72 moves the two toothed plates 73 away from each other. The two smoothing rollers 74 roll above the flat bag, smoothing it. When the smoothing rollers 74 move to both sides of the second heat-sealing plate 5, the cylinder 3 is opened again. The cylinder 3 continues to move the first heat-sealing plate 4 downwards. Finally, the first heat-sealing plate 4 and the second heat-sealing plate 5 heat-seal the flat bag. The smoothing device 7 achieves the effect of smoothing the flat bag, preventing wrinkles and ensuring the flat bag is processed properly.

[0032] Reference Figure 1-6 As shown, a guide plate 6 is fixedly connected to the upper surface of the base 1. The guide plate 6 has a triangular cross-section and is located directly in front of the second heat-sealing plate 5. The guide plate 6 guides the flat bag, facilitating placement between the first heat-sealing plate 4 and the second heat-sealing plate 5. A slider 75 is fixedly connected to the rear side of the first heat-sealing plate 4 via a support plate. A toothed plate 73 has a groove 76 corresponding to the slider 75, allowing the slider 75 to slide smoothly into the groove 76. The movement of the slider 75 on the support plate within the groove 76 of the toothed plate 73 restricts the direction of movement of the toothed plate 73, preventing it from wobbling. A baffle 77 is fixedly connected to one end of the toothed plate 73, located at the opening of the groove 76. The baffle 77 restricts the maximum displacement of the slider 75, preventing it from moving out of the groove 76 of the toothed plate 73.

[0033] Reference Figure 1-6As shown, the auxiliary device 8 includes two symmetrical mounting plates 81, which are fixedly connected to both sides of the base 1.

The arc surface of the bolt 83 is fitted with a washer 86, which is a rubber ring. The washer 86 achieves the effect of protecting the pad 84 and preventing damage from contact between the pad 84 and the mounting plate 81.

[0035] Working principle: When heat-sealing a flat bag, the operator first moves the flat bag and places it between the first heat-sealing plate 4 and the second heat-sealing plate 5 via the guide plate 6. Then, the operator opens the cylinder 3 on the support 2. The cylinder 3 moves the first heat-sealing plate 4 downwards until the smoothing roller 74 presses against the flat bag. After that, the operator turns on the motor 71 on the L-shaped plate. The motor 71 drives the gear 72 to rotate via the reducer. The gear 72 moves the two toothed plates 73 away from each other. The slider 75 on the support plate slides in the groove 7 of the toothed plate 73. The movement of the 6th movement restricts the direction of movement of the toothed plate 73. The two smoothing rollers 74 roll above the flat bag, smoothing the bag. When the smoothing rollers 74 move to both sides of the second heat-sealing plate 5, the cylinder 3 is opened again. The cylinder 3 continues to move the first heat-sealing plate 4 downwards. Finally, the first heat-sealing plate 4 and the second heat-sealing plate 5 heat-seal the flat bag. The smoothing device 7 achieves the effect of smoothing the flat bag, avoiding wrinkles and preventing the flat bag from becoming unqualified.

[0036] When the base 1 needs to be installed, the staff first moves the base 1 to a suitable position, and then moves the bolt 83 through the control block 85 on the pad 84. The bolt 83 passes through the reserved hole 82 of the mounting plate 81 and is inserted into the inside of the bag making machine. Finally, the pad 84 at one end of the bolt 83 is pressed against the surface of the mounting plate 81 with the help of the washer 86, which achieves the effect of fixing the mounting plate 81. The installation effect of the mounting plate 81 and the base 1 is achieved through the auxiliary device 8, which makes it convenient for the staff to disassemble and repair the heat sealing equipment when it is damaged.
