Technical Field

[0001] This utility model relates to the field of disposable tableware processing technology, and in particular to a disposable tableware sealing machine. Background Technology

[0002] Disposable tableware refers to catering utensils intended for short-term use and then discarded. Common materials include plastic, paper, bamboo, wood, and starch-degradable materials. They are widely used in food delivery, fast food restaurants, airline meals, and outdoor activities. They offer advantages such as convenience, hygiene, no need for washing, and portability, meeting the demands of modern fast-paced lifestyles for convenient dining. Common types include disposable lunch boxes, chopsticks, spoons, forks, cups, and straws. In recent years, with increased environmental awareness, many regions have gradually restricted traditional plastic products and promoted biodegradable and recyclable disposable tableware to reduce white pollution.

[0003] The plastic sealing process for disposable tableware typically involves heating thermoplastic materials (such as plastic film) to wrap and seal the product. This process generates heat, and direct release of this heat means that the energy used for heating is not being fully utilized. This not only increases production costs but also wastes energy. If the released heat is not properly treated by an exhaust system, it may cause the temperature in the work area to rise, affecting employee comfort and efficiency.

[0004] Therefore, it is necessary to design a disposable tableware sealing machine to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the disadvantages of direct discharge of heat generated during the plastic sealing process of disposable tableware, which would lead to energy waste and increased production costs, and may also cause the temperature of the work area to rise, affecting the comfort and efficiency of employees, this utility model provides a disposable tableware plastic sealing machine.

[0006] A disposable tableware sealing machine includes a frame, a thermoplastic cover, a controller, an electric heating element, an air pump, an air supply pipe, and a conveying assembly. The thermoplastic cover is fixedly connected to the top of the frame, and the controller is fixedly connected to the front of the thermoplastic cover. The electric heating element is fixedly connected inside the thermoplastic cover and is electrically connected to the controller. The air pump is fixedly sleeved on the top of the thermoplastic cover and is electrically connected to the controller. The air pump is located above the electric heating element. The top of the air pump is connected to and communicates with the air supply pipe. The two bottom ports of the air supply pipe are both connected to and communicate with the lower part of the frame. The conveying assembly is provided on the top of the frame.

[0007] Furthermore, the conveying assembly includes a fixed frame, rollers, a motor, and a conveyor belt. The top of the frame is fixedly connected to the fixed frame, and rollers are rotatably connected to both sides inside the fixed frame. The motor is fixedly connected to the front of the fixed frame. The motor is electrically connected to the controller. The output shaft of the motor passes through the fixed frame and is fixedly connected to one of the rollers. A conveyor belt is wound between the two rollers.

The gantry frame is fixedly connected to the top of the fixed frame, and the electric push rod is fixedly connected to the top of the gantry frame. The electric push rod is electrically connected to the controller. The knife holder is fixedly connected to the telescopic rod of the electric push rod. Hot cutting knives are fixedly connected to both sides of the bottom of the knife holder. Both hot cutting knives are electrically connected to the controller.

[0012] The beneficial effects are as follows: This utility model uses an electric heating sealing device to heat-seal both sides of the plastic sealing film to form a bag-like structure. The plastic bag is then accurately transported to the packaging station by a conveyor belt, and the tableware is automatically put into the bag in conjunction with the guide frame. An electric push rod drives a hot cutter to complete the transverse heat sealing and cutting, ensuring the integrity of the packaging. The thermoplastic cover is heated by an electric heating tube and hot air is circulated by an air pump, which makes the plastic sealing film shrink quickly and fit the surface of the tableware, improving the sealing performance and aesthetics of the packaging. This device has a high degree of automation, is easy to operate, and significantly improves the efficiency of tableware sealing and packaging quality, making it suitable for mass production.

Detailed Implementation

[0018] Example: A disposable tableware sealing machine, such as Figures 1-4 As shown, the system includes a frame 1, a thermoplastic cover 6, a controller 9, an electric heating element 601, an air pump 7, an air supply pipe 8, a fixed frame 2, a roller 3, a motor 4, and a conveyor belt 5. The thermoplastic cover 6 is screwed onto the top left side of the frame 1. The controller 9 is screwed onto the front left side of the thermoplastic cover 6. The electric heating element 601 is screwed onto the inside of the thermoplastic cover 6 and is electrically connected to the controller 9. The air pump 7 is fixedly mounted on the top of the thermoplastic cover 6 and is electrically connected to the controller 9. The air pump 7 is located directly above the electric heating element 601. Above, the top of the air pump 7 is connected to and connected to the air supply pipe 8. The two ports at the bottom of the air supply pipe 8 are connected to and connected to the lower part of the frame 1. The top of the frame 1 is equipped with a fixing frame 2 by screws. Rollers 3 are rotatably connected to the left and right sides inside the fixing frame 2. The right side of the front side of the fixing frame 2 is equipped with a motor 4 by screws. The motor 4 is electrically connected to the controller 9. The output shaft of the motor 4 passes through the fixing frame 2 and is fixedly connected to the roller 3 located on the right side. A conveyor belt 5 is wound between the two rollers 3. Multiple air vents are opened on the conveyor belt 5.

[0019] like Figure 1 and Figure 3 As shown, it also includes a column 10, a connecting rod 11, a guide frame 12, a limiting frame 13, and a soldering iron 14. The column 10 is welded to the right side inside the fixed frame 2. The connecting rod 11 is welded to the left side of the middle part of the column 10. The guide frame 12 is welded to the top of the column 10. The guide frame 12 has an inclined structure with the left side lower than the right side and is located above the conveyor belt 5. The limiting frame 13 is welded to the left end of the connecting rod 11. The soldering iron 14 is installed inside the limiting frame 13 by screws. The soldering iron 14 is electrically connected to the controller 9.

[0020] like Figure 1 and Figure 4 As shown, it also includes a gantry frame 15, an electric push rod 16, a blade holder 17, and a hot cutting blade 18. The gantry frame 15 is installed on the top center side of the fixed frame 2 by screws. The electric push rod 16 is installed on the top of the gantry frame 15 by screws. The electric push rod 16 is electrically connected to the controller 9. The telescopic rod of the electric push rod 16 extends downward and is installed on the blade holder 17 by screws. Hot cutting blades 18 are installed on the left and right sides of the bottom of the blade holder 17 by screws. Both hot cutting blades 18 are electrically connected to the controller 9.

[0021] When disposable tableware needs to be sealed, the sealing film is first guided between the limiting frame 13 and the guide frame 12. The controller 9 starts the soldering iron 14 to heat seal both edges of the sealing film, forming an upward-facing bag-shaped structure. The sealed bag is then pulled onto the conveyor belt 5. Next, the controller 9 starts the motor 4, whose output shaft drives one of the rollers 3 to rotate, driving the conveyor belt 5 to transport the sealed bag to the left side of the device, passing under the gantry 15 and the thermoforming cover 6. At this time, the operator puts the disposable tableware into the guide frame 12 in sequence. The tableware slides into the formed sealed bag along the guide trough. As the conveyor belt 5 continues to run, the sealed bag containing the tableware is transported to directly below the gantry 15. The controller 9 starts the electric push rod 16, which extends... The retracting rod extends downward, pushing the blade holder 17 down so that the hot cutting blade 18 can perform transverse heat sealing and cut the plastic sealing film. After cutting, the telescopic rod of the electric push rod 16 retracts, and the blade holder 17 moves upward to its original position, completing the sealing process of a single piece of tableware. Subsequently, the sealed tableware enters the thermoforming cover 6 along the conveyor belt 5. The electric heating tube 601 is activated by the controller 9 to heat the air and generate hot air. At the same time, the air pump 7 is activated to circulate the hot air into the thermoforming cover 6, causing the plastic sealing film to shrink due to heat and adhere tightly to the surface of the disposable tableware, achieving a good seal. After sealing is completed, the conveyor belt 5 sends the finished product out of the thermoforming cover 6. The operator can remove the sealed disposable tableware at the exit. Finally, the air pump 7, the electric heating tube 601, the electric push rod 16, and the motor 4 are turned off to complete the entire sealing process.
