[0002] Synthetic paper (also known as plastic paper or composite paper) is a type of paper made by combining plastic materials with paper or other materials. This type of paper is waterproof, wear-resistant, and tear-resistant, and is often used to make durable documents, cards, labels, etc. A calender is a device used to surface treat paper or other materials. Its main purpose is to improve the surface smoothness and hardness of the material.

[0003] The heating component of the commonly used calender is a roller type, that is, the roller is heated during use, and then the roller rolls to heat the base paper transmitted forward. Since the roller is a cylindrical structure, the contact between it and the paper is line contact, that is, the contact part between the two is a straight line, which results in a short contact time between the paper and the roller, which can easily lead to insufficient heating. Utility Model Content

[0004] The purpose of the present utility model is to provide a synthetic paper calender, whose surface heating component is in surface contact with the base paper, which can obtain more heating time during heating, thereby heating more fully, so as to solve the problems raised in the above-mentioned background technology.

[0006] Furthermore, the surface heating component includes two correspondingly distributed rollers, both of which are rotatably connected to the inside of the shell, a heating belt is provided between the two rollers, and the two rollers are driven by the heating belt.

[0007] Furthermore, a first reduction motor is fixedly mounted on the outer wall of the housing, and an output shaft of the first reduction motor is fixedly connected to one end of the corresponding roller.

[0008] Furthermore, the heating belt includes a base layer, an outer wall of the base layer is provided with a heat insulation layer, and an outer wall of the heat insulation layer is provided with a stainless steel belt layer.

[0009] Furthermore, the heat source component includes a mounting bracket, which is fixedly installed inside the shell, and the mounting bracket is arranged on the inner side of the corresponding heating belt, and an electromagnetic coil is installed at the bottom of the mounting bracket.

[0010] Furthermore, the pressing assembly includes a mounting frame, the inner side of which is rotatably connected to two upper and lower pressure rollers, a second reduction motor is fixedly mounted on one end of the mounting frame, and an output shaft of the second reduction motor is fixedly connected to one end of one of the pressure rollers.

[0011] Furthermore, two mutually meshing gears are provided at the other end of the mounting frame, and the two gears are fixedly sleeved on the other ends of the two pressing rollers respectively.

[0012] Compared with the prior art, the beneficial effect of the present invention is that the base paper passes through the bottom of the first guide roller and then passes between the two surface heating components.

[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1-3 As shown, a synthetic paper calender includes a base 1 and a reeling frame 2. The top of the base 1 is fixedly connected to the reeling frame 2, a first guide roller 3, a heating assembly 4, a second guide roller 5, a laminating assembly 6 and a reeling frame 7 in sequence from left to right. The heating assembly 4 includes a shell 41 fixedly connected to the top of the base 1. Surface heating components 42 are symmetrically arranged inside the shell 41. A gap is provided between the two surface heating components 42 for synthetic paper to pass through. Heat source components 43 are symmetrically arranged inside the shell 41. The two heat source components 43 are respectively arranged inside the two surface heating components 42.

[0021] According to the above structure, when in use, the synthetic paper base paper roll to be processed is placed on the unwinding rack 2, and the paper roll for winding after processing is placed on the winding rack 7. During operation, the base paper passes through the bottom of the first guide roller 3, and then passes between the two surface heating components 42. The two surface heating components 42 heat the two sides of the base paper respectively, so that the base paper is heated more evenly. After heating, the base paper is pressed and shaped by the pressing component 6 under the guidance of the second guide roller 5, thereby completing the processing. The surface heating component 42 is in surface contact with the base paper, and more heating time can be obtained during heating, so that the heating is more sufficient.

[0022] like Figure 2-4 As shown, the surface heating component 42 includes two correspondingly distributed rollers 421, and the two rollers 421 are rotatably connected to the inside of the shell 41. A heating belt 422 is arranged between the two rollers 421. The two rollers 421 are driven by the heating belt 422. A first reduction motor 423 is fixedly installed on the outer wall of the shell 41, and the output shaft of the first reduction motor 423 is fixedly connected to one end of the corresponding roller 421.

[0023] According to the above structure, when in use, the first reduction motor 423 is started to drive the roller 421 to rotate, thereby driving the heating belt 422 to circulate and rotate, and the side wall of the heating belt 422 contacts the base paper.

[0024] like Figure 3 and 4As shown, the heating belt 422 includes a base layer 424, the outer wall of the base layer 424 is provided with an insulation layer 425, the outer wall of the insulation layer 425 is provided with a stainless steel belt layer 426, and the heat source component 43 includes a mounting bracket 431, the mounting bracket 431 is fixedly installed inside the outer shell 41, the mounting bracket 431 is arranged on the inner side of the corresponding heating belt 422, and an electromagnetic coil 432 is installed at the bottom of the mounting bracket 431.

[0025] According to the above structure, when working, the heat source component 43 is energized, the heat source component 43 generates a magnetic field, and the circulating stainless steel belt layer 426 cuts the surface of the magnetic induction line to generate eddy currents, thereby increasing its own temperature. The heated stainless steel belt layer 426 heats the base paper.

[0026] like Figure 1 and 3 As shown, the pressing assembly 6 includes a mounting frame 61, and two upper and lower pressure rollers 62 are rotatably connected to the inner side of the mounting frame 61. A second reduction motor 63 is fixedly installed at one end of the mounting frame 61, and the output shaft of the second reduction motor 63 is fixedly connected to one end of one of the pressure rollers 62. The other end of the mounting frame 61 is provided with two mutually meshing gears 64, and the two gears 64 are fixedly sleeved on the other ends of the two pressure rollers 62 respectively.

[0027] According to the above structure, the heated base paper passes between the two pressing rollers 62. Driven by the second reduction motor 63 and driven by the two gears 64, the two pressing rollers 62 rotate synchronously in opposite directions, pressing the base paper while driving it forward.

[0028] The working principle of the present invention is as follows: when in use, the synthetic paper base paper roll to be processed is placed on the unwinding rack 2, and the paper roll after winding is placed on the winding rack 7. When working, the base paper passes through the bottom of the first guide roller 3, and then passes between the two surface heating components 42. By starting the first reduction motor 423, the roller 421 is driven to rotate, and then the heating belt 422 is driven to rotate in a circular manner. The side wall of the heating belt 422 is in contact with the base paper. When working, the heat source component 43 is energized, the heat source component 43 generates a magnetic field, and the circularly rotating stainless steel belt layer 426 cuts the surface of the magnetic induction line to generate eddy currents, thereby increasing its own temperature. The heated stainless steel belt layer 426 heats the base paper, and the two surface heating components 42 heat the two sides of the base paper respectively, so that the base paper is heated more evenly. After heating, the base paper is guided by the second guide roller 5 and pressed and shaped by the pressing component 6, thereby completing the processing. The heated base paper passes between the two pressing rollers 62. Driven by the second reduction motor 63 and the transmission of the two gears 64, the two pressing rollers 62 rotate synchronously in opposite directions, and the base paper is pressed while being driven forward. The surface heating component 42 is in surface contact with the base paper, and more heating time can be obtained during heating, so that the heating is more sufficient.
