[0002] Food packaging is an integral part of food products and one of the major engineering processes in the food industry. It protects food from damage caused by biological, chemical, and physical external factors during its distribution from the factory to the consumer. It also helps maintain the stable quality of the food itself. It facilitates the consumption of food and is the first thing consumers notice about the food's appearance, attracting them to the market. It has value beyond material cost. Therefore, the food packaging process is an integral part of the food manufacturing system engineering. Food packaging bags need to be sealed during processing.
[0003] In the existing technology, when sealing food bags, the sealing device needs to use an adjustment mechanism to adjust the position of the food bag, and then use a heat sealing mechanism to heat seal the opening of the food bag, which makes sealing food bags quite troublesome.
[0004] This utility model proposes a sealing device for food packaging to solve the problem that sealing food bags is cumbersome because it requires adjusting the position of the food bag using an adjustment mechanism and then using a heat sealing mechanism to heat seal the bag opening. Utility Model Content
[0005] The purpose of this invention is to overcome the problem in the above-mentioned background technology that when sealing a food bag, the sealing device needs to use an adjustment mechanism to adjust the position of the food bag and then use a heat sealing mechanism to heat seal the opening of the food bag, which makes sealing the food bag quite troublesome.
[0006] Based on the above technical concept, the technical solution adopted by this utility model is as follows: A sealing device for food packaging includes a feeding mechanism. Two electric push rods are symmetrically arranged on the feeding mechanism. A control plate is fixedly connected to the extended ends of the two electric push rods. A winding mechanism is disposed within the control plate. Two hot-pressing mechanisms are symmetrically arranged on the outer wall of the control plate. The two hot-pressing mechanisms are connected to the winding mechanism via steel cables. A toothed plate is fixedly connected to the top surface of the feeding mechanism. The upper end of the toothed plate is inserted into the control plate and engages with the winding mechanism to control its operation. Two pusher plates are symmetrically inserted into the outer wall of the feeding mechanism. The ends of the pusher plates extend out of the feeding mechanism and abut against the inner sidewall of the control plate.
[0007] Further defining the above technical solution, the feeding mechanism includes a frame, two drive shafts and a conveyor belt. The two drive shafts are symmetrically arranged inside the frame and connected by the conveyor belt. Several partition plates are fixedly connected to the surface of the conveyor belt. A motor is fixedly connected to the side wall of the frame, and the rotating shaft of the motor is fixedly connected to one end of the drive shaft.
[0008] Further defining the above technical solution, the control panel includes a horizontal plate and two inclined plates. The horizontal plate is fixedly connected to the extended end of the electric push rod, and the two inclined plates are fixedly connected to the bottom surfaces at both ends of the horizontal plate. The lower ends of the two inclined plates are chamfered.
[0009] As a further limitation of the above technical solution, an installation groove is provided in the horizontal plate, and the winding mechanism is rotatably inserted into the installation groove.
[0010] Further defining the above technical solution, the winding mechanism includes a winding rod, which is rotatably inserted into the mounting groove, and gears are fixedly sleeved at both ends of the winding rod, the gears meshing with the gear plate.
[0011] Further defining the above technical solution, the hot pressing mechanism includes a guide plate and a movable plate. One end of the guide plate is inserted into the mounting groove and fixedly connected to the steel cable. The movable plate is fixedly connected to the other end of the guide plate.

[0012] As a further limitation of the above technical solution, a spring is fixedly connected to the side wall of the movable plate, and the end of the spring away from the movable plate is fixedly connected to the side wall of the horizontal plate.
[0013] Further defining the above technical solution, the pusher plate includes a round rod and a pusher plate. One end of the pusher plate passes through the frame and is fixedly connected to the pusher plate. The pusher plate is connected to the inner side wall of the frame by a tension spring. The other end of the round rod abuts against the side wall of the inclined plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are: The control panel is moved down by an electric push rod, which pushes the pusher plate to move synchronously. The position of the food bag is adjusted by the cooperation of the two pusher plates. At the same time, the toothed plate drives the winding mechanism to rotate and wind up the steel cable.

[0019] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.
[0020] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a sealing device for food packaging, including a feeding mechanism 1. The feeding mechanism 1 includes a frame 11, two drive shafts 12, and a conveyor belt 13. The two drive shafts 12 are symmetrically arranged inside the frame 11 and connected to each other via the conveyor belt 13. Several partition plates 14 are fixedly connected to the surface of the conveyor belt 13. A motor 15 is fixedly connected to the side wall of the frame 11. The rotating shaft of the motor 15 is fixedly connected to one end of the drive shaft 12. The motor 15 facilitates the operation of the drive shaft 12 and the conveyor belt 13, thereby conveying the food bags through the conveyor belt 13 and separating the food bags individually through the partition plates 14 to reduce the possibility of food bags piling up together.
[0021] Two electric push rods 2 are symmetrically arranged on the feeding mechanism 1. The extended ends of the two electric push rods 2 are fixedly connected to a control plate 3. A winding mechanism 4 is arranged inside the control plate 3. Two hot pressing mechanisms 5 are symmetrically arranged on the outer wall of the control plate 3. The two hot pressing mechanisms 5 are connected to the winding mechanism 4 by steel cables 6. The hot pressing mechanism 5 includes a guide plate 51 and a movable plate 52. One end of the guide plate 51 is inserted into the mounting groove 33 and fixedly connected to the steel cable 6. The movable plate 52 is fixedly connected to the other end of the guide plate 51. A heat sealing knife head 53 is fixedly connected to the side wall of the movable plate 52. When the winding rod 41 winds the steel cable 6, the steel cable 6 pulls the guide plate 51 and the movable plate 52 to move, thereby causing the two heat sealing knife heads 53 to fit together. Then, the two heat sealing knife heads 53 cooperate to perform heat sealing treatment on the food bag.
[0022] A toothed plate 7 is fixedly connected to the top surface of the feeding mechanism 1. The upper end of the toothed plate 7 is inserted into the control plate 3 and meshes with the winding mechanism 4 to control the operation of the winding mechanism 4. A spring 54 is fixedly connected to the side wall of the movable plate 52. The end of the spring 54 away from the movable plate 52 is fixedly connected to the side wall of the horizontal plate 31. When the horizontal plate 31 is reset, the toothed plate 7 drives the gear 42 and the winding rod 41 to reset. At this time, the winding rod 41 releases the steel cable 6, and then the spring 54 pushes the guide plate 51, the movable plate 52 and the thermoplastic sealing head 53 to reset.
[0023] It should be noted that the thermoplastic sealing head 53 is an existing product.
[0024] Two pusher plates 8 are symmetrically inserted into the outer wall of the feeding mechanism 1. The ends of the pusher plates 8 extend out of the feeding mechanism 1 and abut against the inner side wall of the control plate 3. The control plate 3 includes a horizontal plate 31 and two inclined plates 32. The horizontal plate 31 is fixedly connected to the extended end of the electric push rod 2. The two inclined plates 32 are fixedly connected to the bottom surfaces at both ends of the horizontal plate 31. The lower ends of the two inclined plates 32 are chamfered. The electric push rod 2 facilitates the control of the horizontal plate 31 and the inclined plates 32 to move up and down. When the inclined plates 32 move down, they push the pusher plates 8 to move, thereby adjusting the position of the food bag through the pusher plates 8.
[0025] The horizontal plate 31 has an installation groove 33, and the winding mechanism 4 is rotatably inserted into the installation groove 33. The installation groove 33 facilitates the installation of the winding mechanism 4.
[0026] The winding mechanism 4 includes a winding rod 41, which is rotatably inserted into the mounting groove 33. Gears 42 are fixedly sleeved at both ends of the winding rod 41. The gears 42 mesh with the toothed plate 7. When the horizontal plate 31 moves, it drives the winding rod 41 to move synchronously. At this time, the toothed plate 7 drives the gears 42 and the winding rod 41 to rotate, thereby winding or releasing the steel cable 6 through the winding rod 41.
[0027] The pusher plate 8 includes a round rod 81 and a pusher plate 82. One end of the pusher plate 82 passes through the frame 11 and is fixedly connected to the pusher plate 82. The pusher plate 82 is connected to the inner side wall of the frame 11 by a tension spring 83. The other end of the round rod 81 abuts against the side wall of the inclined panel 32. When the inclined panel 32 moves down, it pushes the round rod 81 and the pusher plate 82 to move. At this time, the pusher plate 82 pushes the food bag to move so as to adjust the position of the food bag. When the inclined panel 32 separates from the round rod 81, the tension spring 83 pulls the pusher plate 82 and the round rod 81 to reset, so as to reduce the possibility of the pusher plate 82 blocking the normal operation of the feeding mechanism 1.
[0028] It should be noted that when the electric push rod 2 moves the control board 3, the feeding mechanism 1 is in a stopped state, and the control system between the two can use existing technology.
[0029] Working principle: When using this food packaging sealing device, first place the food-filled packaging bag onto the feeding mechanism 1. Then, the feeding mechanism 1 moves the food bag to below the heat-pressing mechanism 5. Then, the electric push rod 2 pulls the control plate 3 down. At this time, the control plate 3 pushes the pusher plate 8 to move synchronously. Thus, the position of the food bag is adjusted by the cooperation of the two pusher plates 8. When the control plate 3 moves down, the toothed plate 7 drives the winding mechanism 4 to rotate and wind up the steel cable 6. Then, the steel cable 6 pulls the heat-pressing mechanism 5 to shrink and heat-seal the opening of the food bag.
[0030] The above description is a further detailed explanation of the present invention in conjunction with specific preferred embodiments, which is intended to enable those skilled in the art to understand and apply the present invention. However, it should not be assumed that the specific implementation of the present invention is limited to these descriptions.
