Description

Technical Field

[0001] This utility model relates to the field of packaging boxes, and in particular to a self-temperature controlled calendering forming roller equipment. Background Technology

[0002] Takeout boxes are a type of food container commonly used in restaurants to pack food; they are typically for single use. Takeout boxes are characterized by their portability and ease of use.

[0003] When processing food packaging boxes, plastic sheets need to be calendered to the appropriate size, requiring the use of calendering rollers. One example is a self-temperature controlled calendering roller for plastic molding, which consists of two rollers, an oil tank, and a temperature control device. The rollers have a chrome-plated outer layer and a through-hole in the center. An oil guide pipe is installed on the oil tank, which is circulated through the through-hole. The temperature control device is located on the oil tank, and a heating device is electrically connected to it. A mold is located on one side of the roller. This self-temperature controlled calendering roller for plastic molding can heat and press the surface of plastic products, improving surface smoothness and offering convenient and reliable adjustment.

[0004] However, when the device is in operation, directly heating the oil in the oil tank can easily cause oil stratification due to the oil's viscosity and internal temperature differences. After stratification, the temperature distribution of each layer becomes uneven, and the temperature difference between the upper and lower layers, as well as between the inner and outer layers, gradually widens. This significantly reduces the overall uniformity of oil heating, thus affecting the uniformity of oil heating and also impacting the heating effect on plastic sheets.

[0005] Therefore, it is necessary to provide a self-controlled temperature calendering roll equipment to solve the above-mentioned technical problems. Utility Model Content

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] First Embodiment

A self-temperature controlled calendering forming roller equipment includes: a mounting frame 1, with grooves 11 on both sides of the mounting frame 1, a first pressure roller 12 rotatably connected to the interior of both sides of the mounting frame 1, a second pressure roller 13 provided on the inner side of the grooves 11, and mounting blocks 14 rotatably connected to both ends of the outer side of the second pressure roller 13;

[0028] Oil tank 3 is fixedly installed at the bottom of the mounting frame 1. A temperature control device 31 is fixedly installed on the front of the oil tank 3. A pump body 32 is fixedly installed at the bottom of the oil tank 3. An input pipe 33 is fixedly installed at the output end of the pump body 32. A throttle valve 34 is fixedly installed on the top of one side of the oil tank 3. A return pipe 35 is fixedly installed at the input end of the throttle valve 34.

[0029] A drive motor 4 is fixedly installed at one end of the oil tank 3. Two rotating disks 41 are provided on the inner side of the oil tank 3. Multiple heating tubes 42 are fixedly installed between the two rotating disks 41. Multiple fixing brackets 43 are fixedly installed on the outer side of each of the multiple heating tubes 42. Multiple stirring blades 44 are fixedly installed on the outer side of each of the multiple fixing brackets 43. One rotating disk 41 is rotatably connected to one side of the inner side of the oil tank 3, and the other rotating disk 41 is fixedly installed at the output end of the drive motor 4.

[0030] An adjusting screw 2 is rotatably connected to the top of the mounting frame 1. A connecting plate 21 is threadedly connected to the outer side of the adjusting screw 2. A connecting rod 22 is fixedly installed at both ends of the bottom of the connecting plate 21. The bottom of the connecting rod 22 is fixedly installed on the top of the mounting block 14.

[0031] Limiting frames 23 are fixedly installed at both ends of the top of the mounting frame 1, and the limiting frames 23 are slidably connected to the outer side of the connecting plate 21.

[0032] When using the plastic sheet, if the thickness needs to be adjusted, the user can rotate the adjusting screw 2, so that the adjusting screw 2 is threaded inside the connecting plate 21, and then the connecting plate 21 drives the two connecting rods 22 to move downward. Then, the two connecting rods 22 drive the second pressure roller 13 to move downward through the mounting block 44, thereby adjusting the distance between the first pressure roller 12 and the second pressure roller 13, so as to stretch the plastic sheet into different thicknesses and sizes.

[0033] The connecting plate 21 slides on the inner side of the two limiting frames 23, which can limit the connecting plate 21 and increase the stability of the connecting plate 21 when it moves up and down.

[0035] The temperature control device 31 and the heating tube 42 are electrically connected.

[0036] When in use, the temperature control device 31 can adjust the heating temperature of the heating tube 42 to keep the oil at a constant temperature.

[0037] The working principle of the self-controlled temperature calendering forming roller equipment provided by this utility model is as follows:

[0038] During use, the user activates the heating element 42 via the temperature control device 31, which heats the oil inside the oil tank 3 to the adjusted temperature. Then, the user activates the pump 32, which draws the oil from the inside of the oil tank 3 and delivers it through the input pipe 33 to the inside of the first pressure roller 12 and the second pressure roller 13, thereby heating the first pressure roller 12 and the second pressure roller 13. Afterward, the oil flows back to the inside of the oil tank 3 through the return pipe 35 and the throttle valve 34. Then, the user activates the drive motor 4, which drives the rotating disk 41 to rotate, thereby rotating the heating element 42 and the stirring blade 44, respectively, to heat and stir the oil inside the oil tank 3, ensuring that the oil is heated evenly.

[0039] Compared with related technologies, the self-controlled temperature calendering forming roller equipment provided by this utility model has the following beneficial effects:

[0040] The oil tank 3, drive motor 4, rotating disk 41, heating tube 42, fixed frame 43 and stirring blade 44 work together to enable the drive motor 4 to drive the rotating disk 41 to rotate during use. The rotating disk 41 then drives the heating tube 42 to heat the oil inside the oil tank 3, and the stirring blade 44 stirs and mixes the oil. This not only increases the uniformity of heating the oil, but also enhances the heating effect on the plastic.
