DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Embodiment: A PET sheet extrusion production line heating and preheating equipment, such as Figure 1-3 As shown, it includes a support base 1, a shell 2, a discharge port 3, a sealing cover 4, a dust cover 5, a handle 501, a support frame 6, a melt tank 7, an overflow port 701, an overflow hole 702, a motor a8, a rotating rod 9, a crushing knife 10, a heating plate 11 and a heating tube 12. The support base 1 is fixedly connected to the shell 2, the discharge port 3 is fixedly connected to the lower part of the shell 2, the sealing cover 4 is clamped on the top of the shell 2, an inverted conical groove is opened on the sealing cover 4, the dust cover 5 is clamped on the groove of the sealing cover 4, the handle 501 is fixedly connected to the dust cover 5, the support frame 6 is fixedly connected to the inside of the shell 2, and the support The frame 6 has two layers, and the melt tank 7 is placed on the support frame 6. Four overflow ports 701 are opened on the top of the melt tank 7, and an overflow hole 702 is opened in the middle and lower part of the melt tank 7. The bottom of the melt tank 7 is fixedly connected to a motor a8, and the output shaft of the motor a8 is fixedly connected to a rotating rod 9, and a crushing knife 10 is fixedly connected to the rotating rod 9. Five crushing knives 10 are arranged on the rotating rod 9, and a heating plate 11 is fixedly connected to the inner wall of the melt tank 7. Two heating plates 11 are arranged on the inner wall of the melt tank 7, and two heating tubes 12 are fixedly connected to the heating plate 11, and two heating tubes 12 are fixedly connected to the bottom of the melt tank 7.

[0020] When it is necessary to put in PET material, the dust cover 5 is opened, and the PET material is put in through the inverted cone groove on the top of the sealing cover 4, and the material enters the melting tank 7 inside the outer shell 2. The motor a8 at the bottom of the melting tank 7 is started, and the motor drives the rotating rod 9 and the crushing knife 10 to rotate to crush the material, so that the material can be heated more evenly, and the material is preheated and melted by the heating plate 11 and the heating tube 12 in the melting tank 7. After the material is melted, it flows outward into the outer shell 2 through the overflow hole 702. When a large amount of material is put in, the melted material will flow out from the overflow port 701 above the melting tank 7 and the overflow hole 702 below the melting tank 7 at the same time, which increases the space in the melting tank 7, so that the operator can continue to put PET material into the inverted cone groove on the top of the sealing cover 4, allowing new material to enter the melting tank 7 and start to melt, which increases the space in the melting tank 7 and improves the efficiency of material preheating.

[0021] like Figure 2 and Figure 3 As shown, it also includes a motor b13, a scraper rod 14 and a silicone sleeve 15. The motor b13 is provided at the bottom of the outer shell 2. The output shaft of the motor b13 passes through the outer shell 2 and is fixedly connected to the scraper rod 14. The scraper rod 14 is inside the outer shell 2. The silicone sleeve 15 is fixedly connected to the scraper rod 14, and the silicone sleeve 15 is close to the inner wall of the outer shell 2.

[0022] The melted material enters the outer shell 2, and the motor b13 is started. The motor b13 drives the scraper rod 14 to rotate. The scraper rod 14 stirs the melted material after heating, which can speed up the fusion speed of the material and reduce the agglomeration of the material. The silicone sleeve 15 on the scraper rod 14 can effectively scrape off the material adhering to the inner wall of the outer shell 2, and can also prevent the scraper rod 14 from damaging the inner wall, thereby fully stirring the material and achieving the effect of reducing material agglomeration and reducing material loss. After the stirring is completed, the preheated material is discharged outward through the discharge port 3, which plays a role in fully stirring the material and achieving the effect of reducing material agglomeration.

[0023] like Figure 2 As shown, it also includes heat dissipation holes 16. The rear of the housing 2 is provided with heat dissipation holes 16. The heat dissipation holes 16 are arranged in two rows, and each row has three heat dissipation holes.

[0024] After use, the hot air is discharged outward through the heat dissipation holes 16, which helps the machine to dissipate heat quickly, thereby achieving the effect of being able to quickly cool the device and prevent overheating.

[0025] like Figure 2 As shown, a sealing ring 17 is also included, and the sealing ring 17 is fixedly connected to the inside of the sealing cover 4.

[0026] The sealing ring 17 can prevent dust and other substances from entering the material when the device is in use, playing a role of waterproof and dustproof, and achieving a sealing effect.

[0027] like Figure 1 As shown, it also includes an observation window 18, and the observation window 18 is fixedly connected to the housing 2.

[0028] The operator can see the state of the material in the shell 2 through the observation window 18, which plays a role in better observing the state of the material in the tank and achieves the effect of facilitating the observation of the state of the material.

[0029] like Figure 1 As shown, a protective cover 19 is also included, and the protective cover 19 is fixedly connected to the handle 501 .

[0030] The protective cover 19 on the handle 501 can prevent burns. When the device has residual temperature, it can prevent burns when grasping the handle 501, thereby protecting the operator from injury.

[0031] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
