Description

Technical Field

[0001] This utility model relates to a heating and sealing mechanism, and more specifically, to a heat sealing mechanism applicable to nickel-chromium heating elements. Background Technology

[0002] With the development of 3C technology, 3C electronic products (mobile phones) are often precise, complex, and highly integrated, with complex manufacturing processes and stringent cleanroom requirements. Mobile phone camera components have consistently failed to meet cleanroom standards, and there is a risk of dust contamination during the camera's manufacturing process and transportation. Vacuum packaging is required before transportation, but the sealing mechanism of vacuum packaging mostly uses nickel-chromium heating elements for heat sealing. However, this structure is relatively simple and bulky, and the heating wire is often fixed by a coiled method. This structure is prone to short circuits and burnouts due to poor connection of the heating wire, which also affects production efficiency and poses safety hazards.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

Both ends of the heating body are provided with clamping members for limiting the heating element from moving away from the heating body. The top of the clamping member is provided with a clamping gap. Both ends of the heating element extend into the clamping gap. The clamping member has elastic deformation properties that cause the clamping gap to open. The clamping member is provided with a plurality of fastening bolts at the clamping gap. The fastening bolts are located on both sides of the heating element.

[0020] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0021] A heat-sealing mechanism for nickel-chromium heating elements, such as Figures 1-4As shown, it includes a heating body 1 and a heating element 2 disposed on the outside of the heating body 1. The heating element 2 is made of nickel-chromium material. The two ends of the heating body 1 are fixedly connected to the connector 4 by bolts. The connector 4 has a U-shaped cross section. The connector 4 is rotatably connected to the clamping element 3 through the shaft hole. The clamping element 3 is made of brass. Two clamping parts are integrally formed on one side of the clamping element 3. There is a gap between the two clamping parts to form a clamping gap 31. The two ends of the heating element 2 extend into the clamping gap 31. Fastening bolts 32 are provided at the clamping parts on the clamping element 3. The fastening bolts 32 are located on both sides of the heating element 2. Because the clamping part 3 is made of brass, it has good elasticity. When the fastening bolt 32 is tightened, the clamping parts come closer together, thereby clamping the heating element 2. Loosening the fastening bolt 32 allows the heating element 2 to be removed for replacement, making the operation more convenient. Furthermore, the clamping part 3 is used for clamping, and the fastening bolt 32 is located on both sides of the heating element 2, making the fixing of the heating element 2 more stable. The fastening bolt 32 will not contact the heating element 2, ensuring its service life. The end face of the clamping part near the heating body 1 is provided with rounded corners to ensure that the heating element 2 slowly transitions from the clamping gap 31 to the top surface of the heating body 1.

[0022] The clamping part 3 is provided with a wire fixing screw 34 on the side near the rotating part. The wire is wrapped around the wire fixing screw 34 and tightened to complete the wiring of the clamping part 3. Since the clamping part 3 is made of brass, it has a good conductivity, which can better heat the heating element 2 and ensure the heat sealing quality.

[0023] An adjusting rod 33 is threaded onto the clamping member 3. The axis of the adjusting rod 33 is perpendicular to the rotation axis of the clamping member 3. One end of the adjusting rod 33 passes through the clamping member 3 and abuts against the inner wall of the connecting member 4. An adjusting hole with a hexagonal cross-section is provided on the end face of the adjusting rod 33. The end of the adjusting rod 33 that abuts against the inner wall of the connecting member 4 has a chamfer, which allows it to be rotated with an Allen wrench. A protective plate 5 is fixedly connected to the side of the connecting member 4 away from the heating body 1. The protective plate 5 effectively protects the wires from being exposed to the outside and easily damaged. The protective plate 5 has a through-hole corresponding to the adjusting rod 33. The cross-sectional area of ​​the through-hole is larger than that of the adjusting rod 33, allowing the Allen wrench to pass smoothly through the through-hole to rotate the adjusting rod 33. No disassembly is required, making the rotation of the adjusting rod 33 more convenient. By setting the adjusting rod 33, the rotation of the adjusting rod 33 can be completed by inserting an Allen wrench into the adjusting hole. The rotation of the adjusting rod 33 can change the distance of the adjusting rod 33 extending out of the clamping member 3. Since the clamping member 3 is rotatably connected in the connecting member 4, when the distance of the adjusting rod 33 extending out of the clamping member 3 is changed, the distance between the clamping member 3 and the inner wall of the connecting member 4 can be controlled, thereby achieving the effect of adjusting the rotation of the clamping member 3. After the heating element 2 is clamped on the clamping member 3, the clamping members 3 located at both ends of the heating body 1 can be adjusted so that the two clamping members 3 rotate in a direction away from or close to each other, which can adjust the tension of the heating element 2 and further ensure the heat sealing quality.

[0024] The top surface of the heating body 1 is provided with Teflon tape 6, and the heating element 2 is located between the Teflon tape 6 and the heating body 1. The Teflon tape 6 covers the side of the heating body 1, thereby covering the heating element 2. On the one hand, this can prevent the nickel-chromium heating wire from directly contacting the material during use, and on the other hand, the pattern on the Teflon surface can increase the aesthetics of the final product. On both sides of the heating body 1, there are symmetrically arranged fixing plates 7 fixedly connected by bolts. The fixing plates 7 are placed outside the Teflon tape 6. The fixing plates 7 are used to press the Teflon tape 6 onto the heating body 1, thus completing the installation of the Teflon tape 6.

[0025] Working principle: Loosen the fastening bolt 32 to open the clamping gap 31, place both ends of the heating element 2 into the clamping gap 31, and tighten the fastening bolt 32. This causes the clamping member 3 to deform, thereby slowly closing the clamping gap 31, thus squeezing the heating element 2 and preventing it from detaching from the heating body 1, completing the installation of the heating element 2. When it is necessary to adjust the tension of the heating element 2, simply use an Allen wrench to rotate the adjusting rod 33, causing the two clamping members 3 to rotate in a direction that moves away from or towards each other, thereby adjusting the tension of the heating element 2. Then, connect the wire using the wire fixing screw 34 to complete the power supply and complete the assembly of the entire heat sealing mechanism. When the heating element 2 is damaged after long-term use, simply loosen the fastening bolt 32 and remove the Teflon tape 6 to replace the heating element 2, making the operation more convenient.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
