Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to an automatic heat shrink packaging machine for barrel-packaged beef noodles. Background Technology

[0002] Bucket-packaged beef noodles are a type of convenience food, usually sold in buckets. They contain noodles, seasoning packets, and beef, among other ingredients. The nutritional content of bucket-packaged beef noodles varies depending on the brand and flavor, but they typically contain high levels of carbohydrates and sodium. During the production process, the storage buckets need to be covered with a film to ensure the long-term preservation of the beef noodles.

[0003] There are still some problems in the use of existing automatic heat shrink packaging machines for barrel-type beef noodles. Due to inaccurate alignment, more heat shrink film may be needed to ensure the integrity of the packaging, thereby increasing material costs. Moreover, after heat shrinking, both the packaging film and the product are in a softened state at high temperatures, making them prone to deformation under external forces, affecting the integrity and appearance of the packaging. Therefore, those skilled in the art have provided an automatic heat shrink packaging machine for barrel-type beef noodles to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic heat-shrink packaging machine for barrel-packaged beef noodles. The machine uses a centering device to center the barrel of the beef noodles and a guiding structure to center the film, which facilitates more precise film application during the packaging process and reduces raw material consumption.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic heat shrink packaging machine for barrel-packaged beef noodles, including a conveying device, wherein grooves are provided on one side of the front and rear inner sidewalls of the conveying device, and a central structure is provided inside each of the two grooves;

[0006] The two central structures include two first electric telescopic rods, which are respectively located at the center of the front inner wall of the groove at the front and at the center of the rear inner wall of the groove at the rear. The output ends of the two first electric telescopic rods are fixedly connected to a base plate. A connecting plate is provided on one side of the front end face of the base plate at the front and on one side of the rear end face of the base plate at the rear. A guide plate is rotatably connected to the center of one side wall of each of the two base plates. A spring is fixedly connected to the center of one side wall of each of the two connecting plates. The two springs are respectively fixedly connected to the center of the front end face of the guide plate at the front and the center of the rear end face of the guide plate at the rear.

[0007] The conveying device is provided with a bracket on one side, and a sliding groove is provided at the center of the upper end face of the bracket near one side, and a guide structure is provided inside the sliding groove;

[0008] Through the above technical solution, the extension and retraction of the two first electric telescopic rods are controlled. The two first electric telescopic rods push the two base plates to move, and then the two connecting plates are pulled by the two springs. The ends of the two connecting plates are always attached to the front and rear inner side walls of the conveying device, which facilitates guiding the bucket of beef noodles to the center position.

[0009] Furthermore, the guide structure includes a first lead screw, which is rotatably connected to the front of the slide groove. A second lead screw is fixedly connected to the rear end of the first lead screw. The front end of the first lead screw passes through the front inner wall of the slide groove and extends to the front end of the bracket. A first servo motor is fixedly connected to the end of the first lead screw. The first servo motor is fixedly connected to the front end face of the bracket. A first slider is threaded onto the outer wall of both the first lead screw and the second lead screw. A guide module is fixedly connected to the upper end of both first sliders. The outer threads of the first lead screw and the second lead screw are arranged in opposite directions.

[0010] The above technical solution controls the start of the first servo motor, which drives the first lead screw to rotate. The first lead screw drives the second lead screw to rotate.

[0012] Through the above technical solution, the first conveyor belt is started, and the bucket of beef noodles is moved onto the film. As the film moves to one side, it is guided by the guide structure and then moves towards the center. The cutting and packaging structure is then started to cut and package the noodles. After packaging, the second conveyor belt is started to transport the cut bucket of beef noodles into the heat shrink structure.

[0013] Furthermore, the heat-shrinkable structure includes an outer shell, a partition fixedly connected to the center of the inner part of the outer shell, a heat insulation plate rotatably connected to the lower end face of the partition, a semiconductor heating element fixedly connected to one side of the center of the upper end face of the outer shell, an air vent provided on the upper end face of the outer shell on one side of the semiconductor heating element, a ventilation pipe fixedly connected to the air vent and the upper end face of the outer shell above the semiconductor heating element, a dustproof net fixedly connected to the center of one side wall of the ventilation pipe, and multiple ventilation fans arranged front and back inside the ventilation pipe on the side of the dustproof net;

[0014] Through the above technical solution, by controlling the activation of the semiconductor heating element and multiple ventilation fans, the heat generated by the hot end of the semiconductor heating element heats the heat-shrinkable film on the second conveyor belt. After the heat-shrinkable film shrinks due to heat, it wraps around the bucket of beef noodles. Then, multiple ventilation fans blow the air from the cold end of the semiconductor heating element to one side, and blow it into the other end of the outer shell through the ventilation pipe and air outlet. The bucket of beef noodles enters the other side of the outer shell after passing through the heat insulation plate, and is cooled by the cold air to prevent the beef noodles from being damaged by excessive temperature. In addition, the semiconductor heating element has low energy consumption and low cost, reducing equipment wear and tear.

[0015] Furthermore, a control box is provided at the rear end of the bracket, a closed structure is provided at one side of the center of the front face of the control box, a pressing structure is provided at one side of the center of the lower end face of the closed structure, and a centrally located membrane placement structure is provided at one side of the lower end of the bracket.

[0039] Working principle: In use, the bucket of beef noodles is placed on the conveyor device 1, and the conveyor device 1 is started to transport the bucket of beef noodles to one side. Then, the two first electric telescopic rods 201 are controlled to extend and retract, and the two first electric telescopic rods 201 push the two base plates 202 to move. Then, the two connecting plates 203 are pulled by the two springs 205. The ends of the two connecting plates 203 are always attached to the front and rear inner side walls of the conveyor device 1, which facilitates guiding the bucket of beef noodles to the center position. Then, the first servo motor 301 is started, and the first servo motor 301 drives the first lead screw 302 to rotate. The first lead screw 302 drives the second lead screw 303 to rotate. The threads on the outer sides of the first lead screw 302 and the second lead screw 303 are set oppositely, so that the two first sliders 304 move synchronously to the front and rear ends or the center position, so that the film is always in the center position. It can also be adjusted according to the size of the film, improving the accuracy of the film and reducing the consumption of the film.

[0040] The first conveyor belt 11 is started, moving the bucket of beef noodles onto the film.

It is initially sealed by the sealing structure 8, and then pressed down by the pressing structure 7 to make the film fit the bucket of beef noodles better. Then the cutting and packaging structure 13 is started to cut and package the noodles. After packaging, the second conveyor belt 12 is started to transport the cut bucket of beef noodles into the outer shell 901.

[0041] By controlling the activation of the semiconductor heating element 904 and multiple ventilation fans 907, the heat generated by the hot end of the semiconductor heating element 904 heats the heat-shrinkable film on the second conveyor belt 12. After the heat-shrinkable film shrinks due to the heat, it wraps around the container of the beef noodles. Then, the multiple ventilation fans 907 blow the air from the cold end of the semiconductor heating element 904 to one side, and blow it into the other end of the outer casing 901 through the ventilation pipe 905 and the air outlet 908. The container of beef noodles enters the other side of the outer casing 901 after passing through the heat insulation plate 903, and is cooled by the cold air to prevent the beef noodles from being damaged by excessive temperature.

[0042] By controlling the extension of the two second electric telescopic rods 402, the two second electric telescopic rods 402 push the mounting frame 403 to move to the front end, take out the take-up drum 410, put in a new heat shrinkable film roll, and then control the two second electric telescopic rods 402 to retract, so that the mounting frame 403 is stored inside the frame 401. Control the start of the third servo motor 404, and the third servo motor 404 drives the third lead screw 405 and the fourth lead screw 406 to rotate. Since the outer threads of the third lead screw 405 and the fourth lead screw 406 are set oppositely, the two placement frames 408 move simultaneously to the center position of the mounting groove 407, clamping the front and rear ends of the heat shrinkable film roll, so that the heat shrinkable film roll is always in the center position, which is convenient for loading.
