[0039] The existing elastic rubber pad is usually adhered to the workbench to ensure good adhesion of the elastic rubber pad and the packaging bag. Since the elastic rubber pad is subjected to high temperature and pressure for a long time, it is easy to be damaged, and the adhesive mode causes the cleaning and replacement process of the elastic rubber pad to be relatively cumbersome.

[0040] The utility model provides a heat sealing machine.

[0041] Please refer to Figure 1 In an embodiment of the utility model, the heat sealing machine 100 comprises:

[0042] A rack 1;

[0043] A heating plate 2 movably arranged in the rack 1;

[0044] The workbench 3 is installed on the frame 1 and is located below the heating plate 2;

[0045] An elastic rubber pad 4 is laid on the upper surface of the workbench 3 and is used to lay the packaging bags to be processed; and

[0046] The positioning structures 5 are detachably provided in plurality, and the plurality of positioning structures 5 are arranged at intervals along the edge of the workbench 3 to clamp and fix the elastic rubber pad 4 on the workbench 3 .

[0047] In the technical solution of the present invention, during the heat sealing process of the packaging bag, the packaging bag needs to be laid on the elastic rubber pad 4 on the surface of the workbench 3, and then the hot pressure sealing of the packaging bag is achieved by moving the heating plate 2 movably arranged above the workbench 3 closer to or away from the workbench 3. In this solution, the elastic rubber pad 4 is clamped and fixed on the workbench 3 by providing a positioning structure 5. The elastic rubber pad 4 is no longer directly adhered to the workbench 3, so it can be easily removed for cleaning or replacement when not in use. By providing multiple positioning points of the elastic rubber pad 4 on the workbench 3 at intervals, the positioning points of the elastic rubber pad 4 on the workbench 3 can be increased, making the fixation of the elastic rubber pad 4 more stable and extending its service life. In addition, by clamping and fixing the elastic rubber pad 4, the hard contact between the packaging bag and the workbench 3 during the heat sealing process is reduced, effectively preventing damage to the packaging bag and ensuring the sterility and safety of medical supplies.

[0048] Specifically, there is no specific limitation on the number of positioning structures 5, and during application, the positioning structures 5 can be selected and set according to the actual size of the workbench 3 on the heat sealing machine 100. In this embodiment, there is no specific limitation on the structure of the positioning structure 5. For example, it can be a C-clamp, a U-clamp, a vise, or other clamps with a clamping and fixing function. It should be pointed out that there is no specific limitation on the material of the elastic rubber pad 4. For example, it can be a rubber pad, or a sponge pad or other elastic material. However, it should be noted that when the heating plate 2 heat-seals the packaging bag, the packaging bag will transfer its own heat to the elastic rubber pad 4. In order to prevent damage caused by heat, the elastic rubber pad 4 should be made of a heat-resistant material.

[0049] In the embodiments of the present invention, please refer to Figure 2 , the positioning structure 5 includes:

[0050] A fixing plate 51 is detachably mounted on the edge of the workbench 3 , with one end of the fixing plate 51 abutting against the side of the elastic pad 4 facing away from the workbench 3 , and the other end of the fixing plate 51 abutting against the side of the workbench 3 facing away from the elastic pad 4 ; and

[0051] The fastener 52 is movably provided at one end of the fixing plate 51 to press and fix the elastic rubber pad 4 and the workbench 3 .

[0052] Specifically, the fastener 52 can be a commonly used fastener such as a screw or a rivet, and the fixing plate 51 can be a U-shaped plate or a C-shaped plate, etc. The two ends of the fixing plate 51 abut against the elastic rubber pad 4 and the workbench respectively, forming a stable clamping structure. The fastener 52 is used to press and fix the elastic rubber pad 4 and the workbench. The pressing action can ensure that the elastic rubber pad 4 is more closely attached to the packaging bag. Through the cooperation of the fixing plate 51 and the fastener 52, the elastic rubber pad 4 can be firmly fixed on the elastic rubber pad 4, preventing displacement. In addition, the installation and disassembly of the elastic rubber pad 4 are more convenient. Optionally, a groove can be provided on the upper surface of the workbench 3, and the size of the groove is slightly larger than the size of the elastic rubber pad 4, so that the elastic rubber pad 4 can be embedded in the groove, and the displacement of the elastic rubber pad 4 is better prevented.

[0053] In the embodiment of the utility model, please refer to Figure 3 and Figure 4 , the fixing plate 51 comprises:

[0054] The main body segment 511 abuts against the side edge of the workbench 3 and the elastic rubber pad 4.

[0055] The first clamping segment 512 is bent and connected to one end of the main body segment 511 and in contact with the elastic rubber pad 4.

[0056] The second clamping segment 513 is oppositely arranged with the first clamping segment 512, is bent and connected to the other end of the main body segment 511 and in contact with the workbench 3. The first clamping segment 512 and / or the second clamping segment 513 is provided with the fastener 52.

[0057] Specifically, the fixing plate 51 comprises the main body segment 511 and the oppositely arranged first clamping segment 512 and second clamping segment 513. The first clamping segment 512 and the second clamping segment 513 are in contact with the elastic rubber pad 4 and the workbench 3 respectively, and can uniformly distribute the pressure applied by the fastener 52, reducing the local compression of the elastic rubber pad 4 and prolonging the service life of the elastic rubber pad 4. Due to the clamping action of the fixing plate 51, the elastic rubber pad 4 can remain flat, thereby ensuring that the contact between the packaging bag and the heating plate 2 during the heat sealing process is more uniform, improving the quality and appearance of the sealing. In addition, the fastener 52 can be separately arranged on the first clamping segment 512 or the second clamping segment 513, so that the operator can easily adjust the clamping force according to the thickness and hardness of the elastic rubber pad 4. Of course, one fastener 52 can be arranged on the first clamping segment 512 and the second clamping segment 513 respectively, so as to adjust the clamping force from the upper and lower directions of the workbench 3.

[0058] In the embodiment of the utility model, please refer to Figure 4The fixed plate 51 further comprises a flexible part 510, which is arranged on the side of the first clamping section 512 facing the elastic rubber pad 4. The flexible part 510 can be made of the same material as the elastic rubber pad 4, such as rubber pad, sponge pad, polyurethane foam, etc. In this way, when the fastener 52 presses the elastic rubber pad 4, the flexible part 510 helps to disperse and absorb the pressure applied by the fastener 52, reducing the direct hard contact on the elastic rubber pad 4, thereby protecting the rubber pad from damage and reducing the frequency and cost of replacement. Optionally, the surface of the flexible part 510 facing the elastic rubber pad 4 is arranged in a wavy shape, which can better absorb part of the impact force and provide additional cushioning effect.

[0059] In the embodiment of the utility model, please refer to Figure 5 The main section 511 comprises a first part 5111, a second part 5112 and a spring 5113, both ends of the spring 5113 are connected with the first part 5111 and the second part 5112 respectively, and the first part 5111 is bendedly connected with the first clamping section 512, and the second part 5112 is bendedly connected with the second clamping section 513. By arranging the spring 5113 between the first part 5111 and the second part 5112, when the elastic rubber pad 4 is thinner, the stretching length of the spring 5113 is shorter; when the elastic rubber pad 4 is thicker, the stretching length of the spring 5113 is longer; the automatic adjusting function of the spring 5113 makes the total length of the main section 511 can be adjusted according to the need, so that it can adapt to elastic rubber pads 4 of different thickness and hardness, so that the heat sealing machine 100 can be suitable for packaging bags of various specifications, and the versatility of the equipment is enhanced.

[0060] In the embodiment of the utility model, please refer to Figure 4 And Figure 5 The bending angle of the first part 5111 and the first clamping section 512 is 90°; optionally, the bending angle of the second part 5112 and the second clamping section 513 is 90°. The bending angle of 90° ensures that the first clamping section 512 and the second clamping section 513 can be in contact with the elastic rubber pad 4 and the workbench 3 vertically, thereby providing stable clamping positioning and reducing the displacement of the rubber pad during the heat sealing process. Moreover, the design of the right-angle bending enhances the overall structural stability of the fixed plate 51, so that the fixed plate 51 is more solid when bearing the pressure and high temperature in the heat sealing process, and is not easy to deform.

[0061] In the embodiment of the utility model, please refer to Figure 5The plurality of springs 5113 are arranged at equal intervals, which can more evenly distribute the pressure on the elastic rubber pad 4, avoid local overpressure, protect the rubber pad from damage, and prolong the service life thereof. The arrangement of the plurality of springs 5113 can automatically adjust the pressure according to the thickness and hardness of the elastic rubber pad 4, so that the equipment can better adapt to packaging bags of different specifications, improve the overall stability of the fixing plate 51, reduce the risk of equipment failure caused by a single spring 5113 failure, and improve the safety and reliability of the equipment.

[0062] In the embodiment of the utility model, please refer to Figure 3 And Figure 4 The connecting part of the main body section 511 and the first clamping section 512 is provided with a chamfer; optionally, the connecting part of the main body section 511 and the second clamping section 513 is provided with a chamfer. The design of the chamfer can smoothly transition the moment of the connecting part, enhance the structural strength between the main body section 511 and the clamping section, and make the fixing plate 51 stable in long-term use. Moreover, the chamfer design avoids sharp edges at the connecting part, reduces the injuries that the operator may suffer in the maintenance and operation process, and improves the safety of the equipment.

[0063] In the embodiment of the utility model, please refer to Figures 3 to 5 The fastener 52 is a screw, the workbench 3 and the fixing plate 51 are both provided with threaded holes, and the screw is threadedly connected with the threaded holes to fix the fixing plate 51.
