Description

Technical Field

[0001] This utility model relates to the technical field of heat sealing devices, specifically a heat sealing device for soft film packaging bags with adjustable sealing width. Background Technology

[0002] Flexible film packaging bags are made of flexible materials (such as polyethylene, polypropylene, aluminum foil, etc.) and are widely used in food, pharmaceuticals, daily chemicals, electronics, and industrial fields. Compared with rigid packaging containers, flexible film packaging bags are an ideal packaging choice for many products due to their lightweight, flexibility, and good sealing properties.

[0003] In the production of flexible film packaging bags, the heat-sealing device is a key piece of equipment for sealing the bags. Traditional heat-sealing devices typically use a fixed-width heat-sealing structure, which cannot flexibly adjust the sealing width according to the packaging bag specifications. This limits the applicability of the equipment, and changing packaging specifications requires replacing the entire sealing module, which is cumbersome and inefficient. Therefore, a heat-sealing device that can adjust the sealing width according to actual needs is needed to improve the equipment's versatility and work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a heat-sealing device for flexible film packaging bags with adjustable sealing width to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat-sealing device for a soft film packaging bag with adjustable sealing width, comprising a heat-sealing machine body, a support block fixedly connected to the bottom end of the heat-sealing machine body, a heat-sealing box fixedly connected to the top end of the heat-sealing machine body, a heat-sealing cavity opened inside the heat-sealing box, an adjustment mechanism provided inside the heat-sealing cavity, a movable groove opened at the top end of the heat-sealing cavity, and a movable block slidably connected to the inner wall of the movable groove.

[0006] As a further preferred embodiment of this technical solution, a cylinder is fixedly connected to the bottom end of the movable block, a heat sealing assembly is fixedly connected to the output end of the cylinder, and a protrusion is fixedly connected to the top end of the movable block.

[0007] As a further preferred embodiment of this technical solution, a fixing block is fixedly connected to the top of the heat sealing box, and a guide rod is fixedly connected to the outer wall of the fixing block. The guide rod passes through and is slidably connected to the inner wall of the protrusion.

[0008] As a further preferred embodiment of this technical solution, the top of the heat sealing box is fixedly connected to an outer shell, the outer wall of the outer shell is fixedly connected to a motor, and a lead screw is fixedly connected to one end of the motor near the outer shell.

[0009] As a further preferred embodiment of this technical solution, the outer wall of the lead screw is threadedly connected to a connecting rod, and the end of the connecting rod away from the lead screw is fixedly connected to the outer surface of the protrusion.

[0010] As a further preferred embodiment of this technical solution, a pressing mechanism is provided at the top of the heat sealing cavity, a fixed pipe is fixedly connected to the top of the heat sealing cavity, a moving block is slidably connected to the inner wall of the fixed pipe, and a pressing plate is fixedly connected to the bottom of the moving block.

[0012] This utility model provides a heat-sealing device for flexible film packaging bags with adjustable sealing width, which has the following beneficial effects: (1) This utility model uses a cylinder to drive the heat sealing assembly to move downward to seal the soft film packaging bag. When the width of the soft film packaging bag to be sealed is wide, the cylinder drives the heat sealing assembly to move upward to disengage from the soft film packaging bag. The motor is turned on, the motor drives the lead screw to rotate, the lead screw rotates to drive the connecting rod to move, the connecting rod moves to drive the protrusion to move on the outer wall of the guide rod, the protrusion moves to drive the movable block to move inside the movable groove. The movable block is used to adjust the position of the heat sealing assembly, and the cylinder drives the heat sealing assembly to seal the soft film packaging bag again. This allows the heat sealing assembly to be flexibly adjusted according to actual needs, thereby adapting to sealing operations of different widths and improving the versatility and work efficiency of the equipment.

[0013] (2) By pulling the handle upward, the handle moves the moving rod upward. The moving rod moves the moving block inside the fixed pipe and the moving block squeezes the spring, thereby causing the pressing plate to disengage from the bottom of the heat sealing cavity. At this time, the soft film packaging bag to be sealed is placed directly below the heat sealing component. When the force on the handle is released, the spring, without being affected by external force, drives the moving block to reset by its own elasticity. The moving block drives the pressing plate to fix the soft film packaging bag. Attached Figure Description

[0018] Among them, the bottom end of the movable block 52 is fixedly connected to the cylinder 53, the output end of the cylinder 53 is fixedly connected to the heat sealing assembly 54, and the top end of the movable block 52 is fixedly connected to the protrusion 55.

[0019] The heat sealing assembly 54 can be moved by the movable block 52, thereby adjusting the sealing width.

[0020] Among them, the top of the heat sealing box 3 is fixedly connected to a fixing block 56, and the outer wall of the fixing block 56 is fixedly connected to a guide rod 57, which passes through and is slidably connected to the inner wall of the protrusion 55.

[0021] The guide rod 57 can restrict the movement trajectory of the protrusion 55.

[0022] The heat sealing box 3 is fixedly connected to the top of the outer shell 58, the outer wall of the outer shell 58 is fixedly connected to the motor 59, and the end of the motor 59 near the outer shell 58 is fixedly connected to the lead screw 510.

[0023] The lead screw 510 can rotate to move the connecting rod 511.

[0024] The lead screw 510 has a connecting rod 511 threaded through its outer wall and connected to it. The end of the connecting rod 511 away from the lead screw 510 is fixedly connected to the outer surface of the protrusion 55.

[0025] The connecting rod 511 can move the protrusion 55 horizontally by moving the connecting rod 511.

[0026] The heat sealing cavity 4 has a pressing mechanism 6 at its inner top, a fixed pipe 61 fixedly connected to the inner top of the heat sealing cavity 4, a moving block 62 slidably connected to the inner wall of the fixed pipe 61, and a pressing plate 63 fixedly connected to the bottom of the moving block 62.

[0027] The pressing mechanism 6 can fix the soft film packaging bag that needs to be sealed, thereby preventing the heat sealing component 54 from sticking to the soft film packaging bag.

[0028] Among them, the top of the movable block 62 is fixedly connected to a spring 64, the top of the spring 64 is fixedly connected to the inner top of the fixed pipe 61, the top of the movable block 62 is fixedly connected to a movable rod 65, and the top of the movable rod 65 is fixedly connected to a handle 66.

[0029] By moving handle 66 upwards, the moving block 62 can be moved using the moving rod 65.

[0030] This utility model provides a heat-sealing device for flexible film packaging bags with adjustable sealing width. The specific working principle is as follows: In use, pull the handle 66 upwards. The handle 66 moves the moving rod 65 upwards. The moving rod 65 moves the moving block 62 inside the fixed pipe 61, and the moving block 62 presses the spring 64, thereby causing the pressing plate 63 to disengage from the bottom of the heat-sealing chamber 4. At this time, place the flexible film packaging bag to be sealed directly below the heat-sealing assembly 54. Release the force on the handle 66. The spring 64, unaffected by external force, uses its own elasticity to reset the moving block 62. The moving block 62 then moves the pressing plate 63 to fix the flexible film packaging bag. Start the cylinder 53, which moves the heat-sealing assembly 54 downwards. When sealing a flexible film packaging bag, if the width of the bag to be sealed is wide, cylinder 53 drives heat sealing component 54 to move upward and disengage from the bag. Motor 59 is then activated, driving lead screw 510 to rotate. The rotation of lead screw 510 causes connecting rod 511 to move, which in turn causes protrusion 55 to move on the outer wall of guide rod 57. The movement of protrusion 55 causes movable block 52 to move inside movable groove 51. Movable block 52 is used to adjust the position of heat sealing component 54, and cylinder 53 is used again to drive heat sealing component 54 to seal the bag. This allows heat sealing component 54 to be flexibly adjusted according to actual needs, thus adapting to sealing operations of different widths and improving the versatility and efficiency of the equipment.
