[0027] In order to make the purpose, technical solutions and advantages of this application clearer, the application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.

[0028] In the related art, a sheet machine is an important equipment for producing lunch boxes. It is used to extrude the melted liquid raw materials into sheets, which are then transported away by cooling rollers after being formed. After a period of use, the cooling rollers of the sheet machine are prone to foreign matter adhering to their surface. If not cleaned in time, local scars may appear on the sheets. Patent No. CN221540590U discloses a sheet machine for producing lunch boxes. The cleaning mechanism sprays coolant on the cooling rollers and cleans them. However, the cooling rollers sprayed with a nozzle have a low effective utilization rate of the coolant.

[0029] This embodiment provides a sheet making machine for producing lunch boxes, and its cleaning mechanism can improve the utilization rate of the cooling liquid.

[0030] See also Figure 1-Figure 2 In this embodiment, a sheet machine for producing lunch boxes includes a cleaning mechanism, which includes a liquid storage tank 10, a bracket 20 and a cleaning roller 30; the bracket 20 is slidingly connected to the liquid storage tank 10, and a spring 23 is provided between the bracket 20 and the liquid storage tank 10; the cleaning roller 30 is rotatably connected to the bracket 20, and two cleaning rollers 30 are arranged in parallel on the bracket 20, and the cleaning roller 30 is arranged parallel to the cooling roller 40 above the liquid storage tank 10, and part of the circumference of the cleaning roller 30 is located below the liquid level of the coolant in the liquid storage tank 10; the spring 23 can make the bracket 20 produce a movement tendency close to the cooling roller 40, so that the cleaning roller 30 and the cooling roller 40 maintain a conflicting state.

[0031] By adopting the technical solution of this embodiment, first, the cleaning roller 30 is kept in contact with the cooling roller 40 under the push of the spring 23, and the friction between the two is used to enable the cleaning roller 30 to rotate along with the cooling roller 40, and the rotation of the cleaning roller 30 will bring out the coolant inside the liquid storage tank 10, so that the coolant adheres to the surface of the cleaning roller 30. Since the cleaning roller 30 and the cooling roller 40 are relatively rotated, the coolant can be transported to the surface of the cooling roller 40. By utilizing the contact connection between the cleaning roller 30 and the cooling roller 40, foreign matter attached to the surface of the cooling roller 40 can be scraped off. At the same time, by utilizing the relative rotation between the cleaning roller 30 and the cooling roller 40, the coolant attached to the surface of the cleaning roller 30 is transported to the surface of the cooling roller 40, which can improve the utilization rate of the coolant, and realize the purpose of providing coolant to the surface of the cooling roller 40 while cleaning the cooling roller 40, so as to improve the utilization rate of the coolant.

[0032] It should be noted that, in the related art, a nozzle is used to spray coolant onto the surface of the cooling roller. Only a small part of the coolant output in this way will adhere to the surface of the cooling roller, and most of the coolant will fall from the cooling roller, resulting in a low effective utilization rate of the output coolant. In this embodiment, the adsorption characteristics of the liquid under the action of surface tension are utilized, and a cleaning roller is used to first absorb the coolant from the cooling box, and then the coolant is transported to the cooling roller through friction and rotation. This not only reduces the output of the coolant, but also improves the effective utilization rate of the output coolant.

[0033] In this embodiment, the liquid storage tank 10 is constructed as a rectangular box with an open top. The liquid storage tank 10 is arranged along the axial direction of the cooling roller 40. The liquid storage tank 10 is arranged below the cooling roller 40, and the liquid storage tank 10 contains coolant.

[0034] In addition, the bracket 20 includes a support plate 21 and a connecting rod 22. The support plate 21 is constructed as a longitudinal rectangular plate as a whole, and the connecting rod 22 is constructed as a longitudinal round rod. An upper connecting sleeve 25 is integrally formed at the middle position of the support plate 21. The top of the connecting rod 22 is inserted into the interior of the upper connecting sleeve 25 and forms a threaded connection with the upper connecting sleeve 25. The connecting rod 22 as a whole is arranged vertically with the support plate 21. A lower connecting sleeve 11 is integrally formed on the outer wall of the liquid storage tank 10. The lower end of the connecting rod 22 passes through the lower connecting sleeve 11, and a sliding connection is formed between the connecting rod 22 and the lower connecting sleeve 11. The spring 23 is integrally arranged on the outside of the connecting rod 22, and the spring 23 is compressed between the upper connecting sleeve 25 and the lower connecting sleeve 11. The spring 23 generates an upward thrust on the upper connecting sleeve 25, so that the bracket 20 as a whole has a movement tendency of moving up and down (that is, approaching the cooling roller 40).

[0035] In order to separate the connecting rod 22 from the upper part of the lower connecting sleeve 11 , a limiting nut 24 is screwed on the lower end of the connecting rod 22 .

[0036] It should be noted that, in this embodiment, the axis of the cooling roller 40 remains horizontally arranged, the liquid storage tank 10 is placed horizontally directly below the cooling tank 40, the connecting rod 22 remains vertically arranged, and the axis of the connecting rod 22 intersects perpendicularly with the axis of the cooling roller 40, the support plate 21 remains horizontally arranged as a whole, the cleaning roller 30 is rotatably connected to the left and right ends of the support plate 21, and the two cleaning rollers 30 are symmetrically arranged on the left and right sides of the connecting rod 22, and part of the circumference of the lower part of the cleaning roller 30 is immersed below the liquid level of the coolant in the liquid storage tank 10, and the circumference of the upper part of the cleaning roller 30 conflicts with the circumference of the lower part of the cooling roller 40.

[0037] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
