Commonly used in industrial production, these heaters offer high efficiency, energy efficiency, and reliability, making them suitable for a wide range of heating applications.

[0003] The heating sleeve in the thick film heater usually needs to be pressed externally during production and processing. When the traditional pressing mechanism presses the heating sleeve, there are problems such as loose pressing and loose edge fit, resulting in relatively poor pressing quality of the heating sleeve. By increasing the pressure of the cylinder, it is easy to cause pressure damage to the heating sleeve, and when the pressure is insufficient, the pressing effect is not obvious. Therefore, a thick film heater pressing mechanism is proposed to solve the above problems. Utility Model Content

[0020] Depend on Figure 1-3 A thick film heater pressing mechanism is given, comprising a base plate 1, an upper end surface of the base plate 1 is equipped with a mounting plate 11, an upper end surface of the mounting plate 11 is equipped with four support rods 2, and the four support rods 2 are distributed in a rectangular shape, the upper ends of the four support rods 2 are jointly equipped with a top plate 3, a cylinder 4 with a guide rod is equipped at the center point of the upper end surface of the top plate 3, an output end of the cylinder 4 with a guide rod is connected to a cylinder guide rod 41, and the cylinder guide rod 41 is vertically arranged, one end of the cylinder guide rod 41 passes through the top plate 3 and is connected to a pressing plate 5, and an upper pressing piece 51 is equipped at the center point of the lower end surface of the pressing plate 5;

[0021] Four second slide bars 7 are mounted on the upper end surface of the mounting plate 11 and are arranged in a rectangular shape. The upper ends of the four second slide bars 7 pass through the pressing plate 5. Second compression springs 71 are sleeved on the outside of the four second slide bars 7. The two ends of the four second compression springs 71 are hooked with the pressing plate 5 and the mounting plate 11 respectively.

[0022] A bearing plate 111 is mounted on the upper end surface of the mounting plate 11 . A pressing member 112 is mounted on the upper end surface of the bearing plate 111 . The pressing member 112 corresponds to the upper pressing member 51 .

[0023] In this embodiment, by controlling the provided guide rod cylinder 4, the guide rod cylinder 4 drives the cylinder guide rod 41 connected to the output end downward and drives the upper pressing piece 51 to press, and through the limiting of the provided four second sliding bars 7 and the auxiliary cooperation of the four second compression springs 71 provided on the outside of the second sliding bars 7, the heating tube sleeve is arranged on the outside of the heating tube 61 and the provided heating device 6 is energized, so that the heating tube 61 installed on one side of the heating device 6 conducts heat to the heating tube sleeve, and finally the upper pressing piece 51 is tightly fitted with the lower pressing piece 112, so that the heating tube sleeve is subjected to film pressing. The provided four second sliding bars 7 help to ensure that the heating tube sleeve is evenly pressurized, avoid the situation where the edges are not tightly fitted, thereby improving the film pressing quality, and the four second compression springs 71 provided on the outside of the second sliding bar 7 can effectively reduce the impact force during the film pressing process, protect the heating tube sleeve from damage, and also protect the equipment from excessive pressure, thereby extending the service life of the equipment.

[0024] Specifically, refer to Figure 1-3 A limit plate 12 is assembled on one side of the bottom plate 1, and two first slide rods 13 are assembled on the upper end surface of the limit plate 12, and the two first slide rods 13 are arranged in parallel. A connecting plate 14 is slidingly provided on the outside of the two first slide rods 13, and a heating device 6 is assembled between the two connecting plates 14. A first compression spring 131 is sleeved on the outside of the two first slide rods 13, and the two ends of the two first compression springs 131 are respectively hooked with the connecting plate 14 and the limit plate 12. A limit block 132 is assembled on the upper end of the two first slide rods 13, and a heating tube 61 is assembled on one side of the heating device 6. The heating tube 61 is located at the upper end of the lower pressure piece 112.

[0025] In this embodiment, when the upper pressure piece 51 is driven to descend, it squeezes and drives the heating tube 61 and the heating tube sleeve outside the heating tube 61. At this time, the heating device 6 and the heating tube 61 are integrated. When the heating tube 61 on one side of the heating device 6 is driven, the heating device 6 is also driven to descend, and drives the two connecting plates 14 installed on the outside, so that the two connecting plates 14 slide downward within the travel range of the first slide bar 13, and squeeze the first compression spring 131 outside the first slide bar 13, so that the first compression spring 131 is in a taut state. Due to the elastic force of the first compression spring 131 itself and the external tension, the first compression spring 131 pushes the connecting plate 14 upward, so that the heating tube 61 can always be in a suitable position during the film pressing process, and the film pressing process of the heating tube sleeve is completed.

[0026] Further preferably, the heating tube 61 is made of brass. Brass has high thermal conductivity, can effectively transfer heat, and improve heating efficiency.

[0027] Specifically, refer to Figure 1-2 The upper ends of the four second sliding rods 7 are all equipped with bolts.

[0028] In this embodiment, the bolt member provided at the upper end of the second slide bar 7 is used to set an upper limit on the pressing plate 5 to prevent the pressing plate 5 from exceeding the travel range of the second slide bar 7 .

[0029] The film pressing mechanism of the thick film heater of the utility model:

[0030] In actual use, the user first connects the set guide rod cylinder 4 to the external air source and gives the cylinder an output value, connects the set heating device 6 to the external power supply, then sets the heating tube sleeve on the outside of the heating tube 61, and sets the outer mold sleeve on the outside of the heating tube sleeve, and then starts the set guide rod cylinder 4, so that the guide rod cylinder 4 drives the cylinder guide rod 41 connected to the output end downward, so that the cylinder guide rod 41 drives the pressing plate 5 connected at one end and the upper pressing piece 51 installed on the lower end surface of the pressing plate 5 to move downward, and the pressing plate 5 is limited by the four second sliding bars 7, so that the pressing plate 5 can be stably lowered when it moves, and at the same time, the set pressing plate 5 squeezes the device when it descends. The second compression spring 71 arranged on the outside of the second slide bar 7 keeps the second compression spring 71 in a taut state. Due to its own elastic force, the second compression spring 71 can reduce the impact during the film pressing process and protect the product. When the upper pressing piece 51 is finally in contact with the lower pressing piece 112 at the lower end, the heating device 6 is started, so that the heating tube 61 installed on one side of the heating device 6 conducts heat to the external heating tube sleeve, so that the heating tube sleeve located between the upper pressing piece 51 and the lower pressing piece 112 finally completes the film pressing process. The cylinder 4 with a guide rod is started to drive the upper pressing piece 51 upward, and the heating tube sleeve after the film pressing is completed is taken out to complete the operation. The above operation is then repeated to continuously perform the film pressing operation.
