Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a heating base for a vacuum packaging machine. Background Technology

[0002] Vacuum packaging machines first vacuum the packaging bags, then heat them through a heating seat, and finally press them together to seal them. Existing heating seats have high-temperature cloth installed on their surface, which covers the heating elements on the heating seat. Because the high-temperature cloth works at high temperatures for a long time, it is prone to aging. When replacing the high-temperature cloth, both sides of the cloth need to be pulled tight and fixed to the sides of the heating seat, which is inconvenient to install. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a heating base for a vacuum packaging machine, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A heating base for a vacuum packaging machine includes a base, a support bar mounted on top of the base, a heating element mounted on top of the support bar, and a high-temperature cloth covered on top of the heating element. A first pressure plate is mounted on one side of the support bar, and one side of the high-temperature cloth is clamped and fixed by the first pressure plate. A winding shaft is provided on the other side of the support bar, and the other side of the high-temperature cloth is wound around the winding shaft. Fixing seats are symmetrically connected to the side of the support bar, and fixing holes are opened on the fixing seats. After the high-temperature cloth is wound around the winding shaft, both sides are locked into the fixing holes of the fixing seats. A second pressure plate is provided on one side of the support bar on the winding shaft. The surface of the second pressure plate is provided with a protrusion. A pressing groove is machined on the side of the support bar corresponding to the protrusion on the surface of the second pressure plate. After the second pressure plate is fixed to the support bar, the protrusion clamps and fixes the other side of the high-temperature cloth.

[0006] Furthermore, the base surface is provided with a clamping seat, the bottom of the support bar is placed inside the clamping seat, and screws are inserted through the clamping seat to lock the support bar.

[0007] Furthermore, conductive copper blocks are installed on both sides of the support bar, the heating element is fixed at both ends on the conductive copper blocks, and an insulating gasket is provided between the conductive copper blocks and the support bar.

[0008] Furthermore, a clamping plate is provided on the winding shaft, and the clamping plate clamps the high-temperature cloth with the winding shaft.

[0009] Furthermore, the fixing opening on the fixing seat is a square opening, and square seats are correspondingly machined on both sides of the winding shaft.

[0010] Furthermore, the raised portions of the first and second pressure plates are machined with serrated grooves.

[0011] Compared with the prior art, the heating seat of the vacuum packaging machine of this utility model can be installed easily and shorten the replacement time of the high temperature cloth by winding the excess high temperature cloth around the cloth shaft, tightening the high temperature cloth, and then clamping the cloth shaft in the fixed seat and pressing and fixing the high temperature cloth by the pressure plate.

Detailed Implementation

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0016] like Figure 1 and Figure 2 As shown, a heating base for a vacuum packaging machine includes a base 1, a support bar 2 mounted on the base 1, a heating element 3 mounted on the support bar 2, and a high-temperature cloth 4 covering the heating element 3. A clamping seat 5 is provided on the surface of the base 1, and the bottom of the support bar 2 is placed inside the clamping seat 5. Screws are threaded through the clamping seat 5 to lock the support bar 2 in place. Conductive copper blocks 6 are mounted on both sides of the support bar 2, and the heating element 3 is fixed at both ends to the conductive copper blocks 6. Insulating gaskets 7 are provided between the conductive copper blocks 6 and the support bar 2. The high-temperature cloth 4 extends towards both sides of the support bar 2 and is fixed to the sides of the support bar 2 by pressure plates.

[0017] A first pressure plate 8 is installed on one side of the support bar 2, and the high-temperature cloth 4 is clamped and fixed on one side by the first pressure plate 8. The surface of the first pressure plate 8 is machined with a serrated groove, which presses the high-temperature cloth 4 and the side of the support bar 2 tightly.

[0018] The other side of the support bar 2 is provided with a winding shaft 9, and the other side of the high-temperature cloth 4 is wound around the winding shaft 9. A clamping plate 10 is provided on the winding shaft 9, and one side of the high-temperature cloth is inserted between the clamping plate 10 and the winding shaft 9. After the clamping plate 10 is fixed, it clamps and fixes the high-temperature cloth 4 with the winding shaft 9.

[0019] The support bar 2 is symmetrically connected to a fixing seat 11 on its side. The fixing seat 11 has a fixing opening. After the high temperature cloth 4 is wound around the cloth shaft 9, the two sides are locked in the fixing opening of the fixing seat 11. In this embodiment, the fixing opening on the fixing seat 11 is a square opening. The two sides of the cloth shaft 9 are correspondingly machined with square seats 12. After the high temperature cloth 4 is wound around the cloth shaft 9, the square seats 12 on both sides of the cloth shaft 9 are locked in the square opening.

[0020] The support bar 2 has a second pressure plate 13 on one side of the fabric shaft 9. The surface of the second pressure plate 13 has a protrusion. The side of the support bar 2 is machined with a pressing groove corresponding to the protrusion on the surface of the second pressure plate 13. After the second pressure plate 13 is fixed to the support bar 2, the protrusion clamps and fixes the other side of the high temperature cloth 4.

[0021] When replacing the high-temperature cloth, first press and fix one side of the high-temperature cloth to the support bar 2 using the first pressure plate 8, then clamp and fix the other side of the high-temperature cloth to the winding shaft 9 using the clamping plate 10, then wind the winding shaft 9, and wind the excess high-temperature cloth onto the winding shaft 9. Then, clamp the winding shaft 9 onto the fixing seat 11, and finally install the second pressure plate 13. The surface of the protruding part of the second pressure plate 13 is also machined with serrated grooves. After the second pressure plate 13 and the support bar 2 are installed, they press the high-temperature cloth 4.
