Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of packaging bag sealing machines, specifically a food packaging bag sealing machine. Background Technology
[0002] Packaging bag sealing machines are key equipment in packaging lines, used to quickly and reliably seal the openings of various flexible packaging bags (such as plastic bags and composite film bags) to ensure that the contents are sealed, kept fresh, leak-proof, and contaminated. Their core working principle is to use heating (heat sealing) or pressure (cold sealing / ultrasonic sealing) to melt and bond or press the inner layer material of the bag opening. They are widely used in the food, pharmaceutical, daily chemical, electronic component, and hardware parts industries.
[0003] The double-sided heating sealing machine is a packaging equipment that uses double-sided synchronous heating technology. The double-sided heat-melting sealing design ensures that the heating plates on both sides are simultaneously pressurized and heated to ensure a uniform and firm sealing line. It is especially suitable for sealing materials such as aluminum foil bags and thick plastic bags. However, some double-sided heating sealing machines require workers to hold both sides of the packaging bag and guide the packaging bag to the space between the heating plates when sealing. The workers' hands are close to the heating plates, which poses a high risk of burns. Therefore, we propose a food packaging bag sealing machine. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a food packaging bag sealing machine. By clamping the sealing position of the packaging bag with a clamping block, the sealing mechanism automatically pushes forward and seals the bag, reducing the possibility of burns and effectively solving the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a food packaging bag sealing machine, comprising a support, a sealing mechanism, and a placement mechanism; Support frame: A support frame is fixedly connected to its upper surface; Sealing mechanism: It includes a mounting frame, an upper sealing seat and a lower sealing seat. The mounting frame is located inside the support frame. The lower sealing seat is fixedly connected to the bottom wall of the mounting frame. The upper sealing seat is located in the middle of the mounting frame. Heating plates are provided on the opposite inner surfaces of the upper sealing seat and the lower sealing seat. The placement mechanism includes an adjusting plate, a fixing frame, clamps, and a mounting plate. The adjusting plate is fixedly connected to the upper front side of the support. The upper end of the adjusting plate is provided with symmetrically distributed fixing frames. Clamps are fixedly connected to the upper inner sides of the two fixing frames. The lower front side of the support is fixedly connected to the mounting plate. The clamps hold the sealing position of the packaging bag, and the sealing mechanism automatically pushes forward and seals the bag, reducing the possibility of burns.
[0006] Furthermore, it also includes a microcontroller, which is located on the right side of the mounting plate. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the heating plate are electrically connected to the output terminals of the microcontroller, controlling electrical appliances.
[0007] Furthermore, the placement mechanism also includes a mounting groove, which is symmetrically arranged on the upper surface of the adjustment plate. The fixing brackets are all connected between the two adjustment plates by bolts, which facilitates the adjustment of the distance between the two clamping blocks.
[0008] Furthermore, the placement mechanism also includes a second mounting groove and a placement plate. The second mounting groove is evenly opened on the front side of the mounting plate, and the second mounting groove is connected to the placement plate by bolts, which facilitates the placement of food packaging bags containing products.
[0009] Furthermore, the sealing mechanism also includes a connecting plate and a cylinder. The cylinder is symmetrically fixedly connected to the top wall of the mounting frame on the left and right sides. The connecting plate is fixedly connected between the lower ends of the telescopic ends of the cylinder and the upper surface of the upper sealing seat. The air inlets of the cylinders are all connected to an external air pump to realize the downward movement of the upper sealing seat.
[0010] Furthermore, the sealing mechanism also includes sliding rods, which are uniformly fixed to the inner walls of the left and right sides of the support frame. The rear ends of the sliding rods are all inclined downwards. The mounting frame is slidably connected between the sliding rods. The rear end of the upper surface of the support frame is rotatably connected to a second cylinder via a rotating seat. The telescopic end of the second cylinder is rotatably connected to the middle of the rear side of the lower sealing seat via a pin, thereby realizing the position movement of the mounting frame.
[0011] Furthermore, a counterweight frame is fixedly connected to the lower end of the bracket to lower the center of gravity.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This food packaging bag sealing machine has the following advantages: When sealing food packaging bags, the opening of the food packaging bag is fixed by inserting the left and right ends of the opening into the gaps of two clamps. Then, the whole assembly consisting of the frame, upper sealing seat and lower sealing seat moves forward and upward to the opening position of the food packaging bag to seal it. The sealing process does not require the worker to hold the food packaging bag, and the heating plate is far away from the worker's hands during the preparation process, reducing the possibility of burns.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-3 This embodiment provides a technical solution: a food packaging bag sealing machine, including a support 1, a sealing mechanism 3 and a placement mechanism 5; Support 1: A support frame 2 is fixedly connected to its upper surface, and a counterweight frame 6 is fixedly connected to the lower end of the support 1; Sealing mechanism 3: It includes a mounting frame 31, an upper sealing seat 32, and a lower sealing seat 35. The mounting frame 31 is located inside the support frame 2. The lower sealing seat 35 is fixedly connected to the bottom wall of the mounting frame 31. The upper sealing seat 32 is located in the middle of the mounting frame 31. Heating plates 7 are provided on the opposite inner surfaces of the upper sealing seat 32 and the lower sealing seat 35. The sealing mechanism 3 also includes a connecting plate 33 and cylinders 34. Cylinders 34 are symmetrically fixedly connected to the top wall of the mounting frame 31. The lower ends of the telescopic ends of cylinders 34 are fixedly connected to the connecting plate 33. The connecting plate 33 is fixedly connected to the upper surface of the upper sealing seat 32. The air inlets of cylinders 34 are all connected to an external air pump. The sealing mechanism 3 also includes slide rods 36. Slide rods 36 are evenly fixedly connected to the left and right sides of the support frame 2. The rear ends of the slide rods 36 on both right inner walls are inclined downwards. The mounting frame 31 is slidably connected between the slide rods 36. The rear end of the upper surface of the bracket 1 is rotatably connected to the cylinder 8 through the rotating seat. The telescopic end of the cylinder 8 is rotatably connected to the middle of the rear side of the lower sealing seat 35 through the pin. When the telescopic end of the cylinder 8 is pushed out, the whole assembly consisting of the mounting frame 31 and the lower sealing seat 35 is pushed forward between the slide rods 36. The rear ends of the slide rods 36 are inclined downwards, so that the mounting frame 31 moves forward and upward at the same time, so as to prevent the lower sealing seat 35 from hitting the opening of the food packaging bag. Then the telescopic end of the cylinder 34 extends, and the whole assembly consisting of the upper sealing seat 32 and the connecting plate 33 moves down. The two heating plates 7 are ceramic substrates, and heating wires are inserted inside to clamp the opening of the food packaging bag for sealing. The placement mechanism 5 includes an adjusting plate 51, a fixing frame 53, a clamping block 54, and a mounting plate 55. The adjusting plate 51 is fixedly connected to the upper front side of the bracket 1. The upper end of the adjusting plate 51 is provided with symmetrically distributed fixing frames 53. The upper ends of the opposite inner sides of the two fixing frames 53 are fixedly connected with clamping blocks 54. The lower end of the front side of the bracket 1 is fixedly connected with the mounting plate 55. The placement mechanism 5 also includes a mounting groove 52, which is symmetrically arranged on the upper surface of the adjusting plate 51. The fixing frames 53 are all connected between the two adjusting plates 51 by bolts. Mounting slots 56 and 57 are evenly spaced on the front side of mounting plate 55. Mounting slots 56 are connected to mounting plate 57 by bolts. The food packaging bag to be sealed is placed on mounting plate 57. The left and right ends of the opening of the food packaging bag are inserted into the gaps between the two clamping blocks 54. The relative distance between the two fixing brackets 53 can be adjusted by mounting slot 52 to adjust the spacing between the two clamping blocks 54, which can accommodate food packaging bags of different widths. The relative height of mounting plate 57 can also be adjusted to facilitate the placement of food packaging bags of different heights, which has high adaptability.
[0017] It also includes a microcontroller 4, which is located on the right side of the mounting plate 55. The input terminal of the microcontroller 4 is electrically connected to an external power supply, and the input terminals of the heating plate 7 are all electrically connected to the output terminals of the microcontroller 4.
[0018] The working principle of the food packaging bag sealing machine provided by this utility model is as follows: The food packaging bag to be sealed is placed on the placement plate 57. The left and right ends of the opening of the food packaging bag are respectively inserted into the gaps between the two clamping blocks 54. Then, the microcontroller 4 controls the external air pump to start, controlling the operation of cylinder 34 and cylinder 8. The telescopic end of cylinder 8 extends, pushing the assembly of the mounting frame 31 and the lower sealing seat 35 forward between the sliding rods 36. The rear ends of the sliding rods 36 are all tilted downwards, causing the mounting frame 31 to move forward and upward simultaneously, preventing the lower sealing seat 35 from hitting the opening of the food packaging bag. Subsequently, the telescopic end of cylinder 34 extends, and the entire assembly consisting of upper sealing seat 32 and connecting plate 33 moves downward. The two heating plates 7 are ceramic substrates, and heating wires are inserted inside the ceramic substrates to heat and clamp the opening of the food packaging bag for sealing. The relative distance between the two fixing brackets 53 can be adjusted through the mounting slot 52 to adjust the spacing between the two clamping blocks 54, adapting to food packaging bags of different widths. The relative height of the placement plate 57 can also be adjusted to facilitate the placement of food packaging bags of different heights, giving it high adaptability. The counterweight frame 6 can hold heavy objects, causing the center of gravity of the support 1 to face backward, preventing the support 1 from tipping forward.
[0019] It is worth noting that the microcontroller 4 disclosed in the above embodiments can be a PIC16F1823-I / P model microcontroller, and the control switch group controls the operation of the external air pump and heating plate (7) using methods commonly used in the prior art.
