[0022] The present utility model provides the following description with reference to the drawings to help a comprehensive understanding of various embodiments of the present utility model as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be regarded as merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present utility model.

[0023] In the description of the present utility model, orientation descriptions are involved. For example, the orientations or positional relationships indicated by up, down, front, back, left, right, etc. are based on the orientations or positional relationships shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0024] It should be understood that when an element (e.g., the first element) is "connected" to another element (e.g., the second element), the element can be directly connected to the other element, or there can be an intermediate element (e.g., the third element) between the element and the other element.

[0025] An embodiment of the present utility model provides a steam shrink packaging machine, as Figures 1-4 shown, including:

[0026] A frame 100, the frame 100 includes a steam generating device 110, and a conveying device 120 is provided on the upper surface of the frame 100;

[0027] A steam box 200, which is arranged on the frame 100 and above the conveying device 120. A first steam suction pipe 210 is provided at the center of the top of the steam box 200. The steam box 200 includes an inlet 220 and an outlet 230 arranged according to the conveying direction of the conveyor belt. Second steam suction pipes 240 and third steam suction pipes 250 are respectively provided at the top of the steam box 200 near the inlet 220 and the outlet 230;

[0028] A steam extraction device, which is connected to the first steam suction pipe 210, the second steam suction pipe 240, and the third steam suction pipe 250.

[0029] The frame 100 supports all other components. A steam generating device 110 is provided on the frame 100, which is a component for generating steam and is used to provide the heat source required for shrink packaging. The conveying device 120 is located on the upper surface of the frame 100 and is used to convey products or packaged items through the steam box 200 for shrink packaging. The steam box 200 is designed with an inlet 220 and an outlet 230 to facilitate the entry of products and the removal after packaging is completed. The first steam suction pipe 210 is located at the center of the top of the steam box 200 and is used to discharge or collect excess steam. The second steam suction pipe 240 and the third steam suction pipe 250 are respectively arranged at the top of the steam box 200 near the inlet 220 and the outlet 230. An air extraction device (not shown in the figure) is connected to the first steam suction pipe 210, the second steam suction pipe 240, and the third steam suction pipe 250. The air extraction device is used to extract steam. The air extraction device is prior art and will not be elaborated here. These steam suction pipes suck away the excess steam overflowing to the inlet 220 or the outlet 230. By using steam suction pipes to suck away the overflowing steam instead of physically blocking the steam, it can prevent the physical blockage from affecting the entry of products into the steam box 200 while preventing steam from overflowing into the operating environment.

[0030] In some embodiments, the frame 100 has a first end face 150. In the conveying direction of the conveying device 120, there is an extension cavity 260 between the inlet 220 and the first end face 150, and the second steam suction pipe 240 is arranged at the top of the extension cavity 260.

[0031] The extension cavity 260 of the steam box 200 is designed such that the extension cavity 260 protrudes from the frame 100, and the second steam suction pipe 240 is arranged at the top of the extension cavity 260. In some specific application scenarios, such as Figure 5 As shown, the steam shrink packaging machine of the present utility model is connected to an intermittent conveying line 300. Goods are intermittently conveyed to the inlet 220 by the intermittent conveying line 300. When the first piece of goods reaches the inlet 220, it needs to wait for the second piece of goods to arrive and push the first piece of goods into the conveying device 120. During the waiting process of the first piece of goods, the design of the extension cavity 260 can utilize the steam overflowing to the inlet 220 to pre-shrink the first piece of goods, prevent steam from entering the inside of the packaging bag, and improve the working efficiency and packaging quality of the steam shrink packaging machine. By analogy, the goods waiting to enter the conveying device 120 at the extension cavity 260 are pre-shrunk, making full use of the steam generated by the steam generating device 110.

[0032] In some embodiments, it further includes a guiding device 270 for guiding goods through the steam box 200. The guiding device 270 includes two guiding rods 280 relatively fixed on the frame 100.

[0033] The guiding device 270 includes two guiding rods 280 relatively fixed on the frame 100, which are used to ensure that the goods can pass through the steam box 200 smoothly and stably, improving the efficiency and accuracy of the packaging process. As the core components of the guiding device 270, the guiding rods 280 are relatively fixed on the frame 100 and provide a stable guiding function for the movement of the goods.

[0034] Further, the two guiding rods 280 cooperate to form a conveying channel 290. At the conveying channel inlet and the conveying channel outlet of the conveying channel 290, the two guiding rods 280 bend towards both sides of the steam box 200 to form a horn shape.

[0035] The two guiding rods 280 cooperate to form a conveying channel 290, and bend towards both sides of the steam box 200 to form a horn shape at the conveying channel inlet and the conveying channel outlet. Such a design helps to guide the goods to enter and leave the steam box 200 smoothly, ensuring the stability and accuracy of the goods during the conveying process. This horn-shaped structural design of the guiding rods 280 can enhance the guiding effect, making the goods enter the steam box 200 more smoothly and reducing the deviation or jamming phenomena that may occur during the high-speed conveying process of the goods.

[0036] In some embodiments, the ends of the guiding rods 280 are hemispherical.

[0037] The ends of the guiding rods 280 are designed to be hemispherical, and such a design may help to improve the smoothness of the guiding rods 280 during movement and reduce friction.

[0038] Further, rubber sleeves are sleeved on the ends of the guiding rods 280.

[0039] Rubber sleeves are sleeved on the ends of the guiding rods 280, which are used to improve the service life of the guiding rods 280 and reduce friction.

[0040] In some embodiments, the conveying device 120 includes a conveyor belt 130 for discharging condensed water.

[0041] The conveying device 120 includes a conveyor belt 130 for discharging condensed water to ensure that the condensed water generated during the packaging process can be effectively discharged, avoiding affecting the packaging effect and the normal operation of the machine.

[0042] Further, the conveyor belt 130 is provided with through holes 140 arranged in an array.

[0043] The conveyor belt 130 is provided with through holes 140 arranged in an array, and such a design helps to improve the air permeability and drainage performance of the conveyor belt 130, especially in the application scenarios where condensed water needs to be discharged.

[0044] The terms and words used in the above description and claims are not limited to their literal meanings, but are used by the applicant to enable a clear and consistent understanding of the present utility model. Therefore, those skilled in the art should clearly understand that the above description of various embodiments of the present utility model is provided for illustration only and not for limiting the present utility model as defined by the appended claims and their equivalents.
