Description

Technical Field

[0001] The utility model relates to the technical field of fusion welding machines, and more specifically, to an accordion protective cover for a fusion welding machine. Background Art

[0002] A fusion welding machine is a machine that energizes an electric hot melt belt to heat up the electric heating wire embedded in the electric hot melt belt. The heat energy generated by the heating wire melts the surface of the pipes and fittings, and welds the plastic pipes together after cooling and solidifying. Its working environment is often characterized by high temperature and smoke. Therefore, protective devices are often required to protect its moving mechanisms such as slide rails or guide rails. The functional requirements of the protective device are that, on the one hand, it needs to be sufficiently sealed to prevent dust or debris from entering the moving mechanism; on the other hand, it needs to have a good heat dissipation effect.

[0003] At present, the accordion protective cover is an important component in the fusion welding machine. The accordion protective cover is generally set on the outside of the moving mechanism such as the slide rail or the guide rail to prevent external dust or powder generated by processing from entering the moving mechanism and causing damage to the device. The existing accordion protective cover is generally made of flexible materials. For example, the Chinese utility model patent with the announcement number CN213570600U discloses a heat treatment device for forging process. The device relates to a heat treatment device for forging process, which has an accordion cover body fixed with screws on one side of the slide, so that the heat treatment equipment does not need to be clamped by workers, saving time and effort, and avoiding the generation of high-temperature steam or oil smoke when it is sprayed on the skin of workers to cause harm. However, the problem of the accordion cover body of this type of high-temperature equipment is that the accordion protective cover has poor resistance to protection after encountering external collision, and the accordion protective cover is easy to dent, and it is easy to be damaged when it is pulled up and compressed again, and the moving mechanism generates a lot of heat by friction when working for a long time. If this heat is not discharged in time, it will affect the service life of the guide rail, thereby causing high processing costs.

[0004] Therefore, it is necessary to design an accordion protective cover based on the working environment characteristics of the fusion welding machine, which can not only protect against the entry of external dust or chips generated during processing, but also has good protection ability, is not easy to deform and damage, and has good heat dissipation effect.

[0035] Torsion spring: A torsion spring is a type of coil spring that includes two torsion arms at the ends, which are generally fixed to other components.

[0037] Example 1

[0038] This embodiment provides a accordion protective cover 9 for a fusion welding machine, combined with Figure 1-4 , comprising an accordion cover body 1 and fixing plates 2 arranged at the upper and lower ends of the accordion cover body 1, the fixing plates 2 and the accordion cover body 1 are fixedly connected; the fixing plates 2 and the accordion cover body 1 enclose a closed space; the accordion cover body 1 comprises a plurality of hinges 11, and the hinges 11 are provided with a fixed rebound mechanism 12 for restoring the hinges 11 after deformation; a cooling port 21 connected to the interior of the accordion cover body 1 is provided on the fixing plate 2 at the upper end of the accordion cover body 1, a heat conducting block 3 is provided in the cooling port 21, and a heat dissipation plate 4 is provided on the top of the heat conducting block 3; a through port 22 for inserting a moving mechanism on a fusion welding machine 5 is provided on the fixing plate 2, and preferably, the accordion cover body 1 is a component of high temperature resistant material.

[0039] As an optional solution, a fixing frame 6 is fixedly connected to the peripheral side of the fixing plate 2, and a connecting portion 7 for fixing the fixing plate 2 to the fusion welding machine 5 is provided on the fixing frame 6. The purpose of providing the fixing frame 6 is to fix the fixing plate 2 to the fusion welding machine 5, so that the accordion protective cover 9 for the fusion welding machine is fixed to the fusion welding machine 5. Preferably, the connecting portion 7 is a bolt hole provided on the fixing frame 6, and it can be fixed by the bolts on the fusion welding machine 5. Preferably, the fixing frame 6 is rectangular, which is a shape commonly used in the art and can be applied to most fusion welding machines 5.

[0040] As an optional solution, the inner wall of the through-port 22 is provided with a sealing ring 8 for increasing the airtightness between the through-port 22 and the moving mechanism on the fusion welding machine 5 inserted into the through-port 22. The sealing ring 8 and the inner wall of the through-port 22 are vulcanized into an integral piece, and the sealing ring 8 is a high-temperature resistant rubber material component. Preferably, the number of the through-ports 22 is 2, and the through-ports 22 are symmetrically arranged on the fixing plate 2. In fact, the number of the through-ports 22 can be set according to actual needs, as long as the moving mechanism on the fusion welding machine 5 can be inserted and fixed. The through-ports 22 are arranged symmetrically, which can increase the stability of the combination of the through-ports 22 and the moving mechanism on the fusion welding machine 5.

[0041] In the specific implementation process, the fusion welding machine 5 inserts its moving mechanism through the opening 22 into the enclosed space formed by the fixed plate 2 and the accordion cover body 1, and keeps moving to generate heat; the fixing frame 6 on the side of the fixed plate 2 fixes the fixed plate 2 on the fusion welding machine 5 through the connecting part 7, so that the fusion welding machine 5 is fixed on the fusion welding machine 5 with the accordion protective cover 9. The moving mechanism on the fusion welding machine 5 keeps reciprocating up and down, and at this time, the movement trend of the fixed plate 2 is consistent with the moving mechanism on the fusion welding machine 5, thereby driving the accordion cover body 1 to rise or compress, and a large amount of heat is accumulated in the accordion cover body 1. The utility model prevents dust and smoke from entering the moving mechanism of the fusion welding machine 5 by enclosing the fixed plate 2 and the accordion cover body 1 into a closed space, and provides a fixed rebound mechanism 12 for restoring the folds 11 after deformation at the multiple hinges 11 included in the accordion cover body 1, so that the accordion cover body 1 is easier to recover after deformation and is not easy to be deformed and damaged; and a cooling port 21 connected to the interior of the accordion cover body 1 is provided on the fixed plate 2 to quickly transfer the heat inside the accordion cover body 1, so as to achieve good heat dissipation effect. The fusion welding machine 5 including the above-mentioned accordion protective cover 9 for the fusion welding machine has a simple structure and low cost, and is suitable for dust prevention, heat dissipation and easily deformed accordion protective covers of the moving mechanism in the fusion welding machine 5 and other types of high-temperature working devices.

[0042] Example 2

[0043] In order to further improve the fixed rebound mechanism 12 of the accordion protective cover 9 for the fusion welding machine of the utility model to act on the hinge 11 on the accordion cover body 1 and improve its recovery effect, on the basis of embodiment 1, combined with Figure 4 and Figure 5 The present embodiment provides another accordion protective cover 9 for a fusion welding machine. As an optional solution, the fixed rebound mechanism 12 includes an upper rod 121 and a lower rod 122. The upper rod 121 and the lower rod 122 are respectively fixedly connected to the two inner walls of the hinge 11. A strip groove is provided on the bottom surface of the upper rod 121. One end of the lower rod 122 is arranged in the strip groove. A rotating shaft 123 is passed through the upper rod 121. The lower rod 122 is rotatably connected to the upper rod 121 through the rotating shaft 123.

[0044] In the specific implementation process, since the hinge 11 itself has elasticity, when the hinge 11 is expanded by external force, the upper rod 121 and the lower rod 122 will be pulled by the hinge 11, so that the upper rod 121 and the lower rod 122 rotate in opposite directions, and the angle becomes larger. When the angle increases to 180°, since the lower rod 122 cannot rotate, the hinge 11 will no longer be deformed, and the upper rod 121 and the lower rod 122 bear the external force on the hinge 11. When the hinge 11 is contracted by the outside, the upper rod 121 and the lower rod 122 will be pressed by the hinge 11, so that the upper rod 121 and the lower rod 122 rotate in opposite directions, and the angle becomes smaller. When the angle is reduced to 0°, since the lower rod 122 cannot rotate and is received in the strip groove of the upper rod 121, the hinge 11 will no longer be deformed, and the upper rod 121 and the lower rod 122 bear the external pressure jointly with the hinge 11.

[0045] As an optional solution, a torsion spring is provided on the rotating shaft 123, and the torsion spring includes two torsion arms. A groove for accommodating the torsion spring is provided on the middle outer wall of the rotating shaft 123, and the main body of the torsion spring is sleeved outside the groove, and the two torsion arms are respectively against the side walls of the upper rod 121 and the lower rod 122 in the rotation direction. In the specific implementation process, when the hinge 11 is contracted or expanded by an external force, the torsion spring is respectively subjected to an external force of compression or tension. At this time, the torsion spring generates a rotational force to cause the hinge 11 to return to its original shape, thereby preventing damage or failure to return to its original shape due to excessive deformation, thereby losing the protective function.

[0046] Preferably, the angle between the upper rod 121 and the lower rod 122 is 0-180°. When the angle between the upper rod 121 and the lower rod 122 is 180°, the two rods are straight as a whole and cannot be deformed. In actual use, the angle between the upper rod 121 and the lower rod 122 is generally 30-60°. Those skilled in the art can set different angles according to the elasticity of the actual material of the accordion cover body 1, so that the fixed rebound mechanism 12 can finally return to its initial structural state before the accordion cover body 1 is deformed and damaged.

[0047] Example 3

[0048] In order to further achieve the heat dissipation effect of the accordion protective cover 9 for the fusion welding machine of the utility model, on the basis of embodiment 1, combined with the attached Figure 2 and Figure 3 This embodiment provides another accordion protective cover 9 for a fusion welding machine. As an optional solution, the heat conductive block 3 is consistent with the cooling port 21 in size. The heat conductive block 3 is filled into the cooling port 21 to seal it, preventing dust from entering the moving mechanism on the fusion welding machine 5 and causing friction to damage the machine.

[0049] In order to further increase the heat dissipation effect, as an optional solution, the heat dissipation plates 4 are arranged at equal intervals on the heat conductive block 3, and the heat dissipation plates 4 are fixedly connected to the heat conductive block 3. The interval arrangement of multiple heat dissipation plates 4 is conducive to rapid heat transmission. Preferably, the heat dissipation plates 4 are arranged perpendicular to the heat conductive block 3, and the heat dissipation plates 4 are fin-shaped.

[0050] Preferably, the heat sink 4 and the heat conducting block 3 are both made of metal components with fast thermal conductivity, preferably copper or its alloy.

[0051] In the specific implementation process, when heat is generated inside the accordion protective cover 9 of the fusion welding machine, the heat will be transferred upward, first passing through the heat-conducting block 3 with good thermal conductivity, and then conducted by the heat-conducting block 3 to the heat sink 4 with a large specific surface area, so that the heat generated inside the accordion protective cover 9 of the fusion welding machine can be quickly transferred out to avoid damage caused by heat accumulation.

[0052] With respect to the above embodiments, it should be noted that the specific model specifications of each component in the above embodiments 1-3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field; the materials of each component are selected from general materials in the existing technology, and no improvement is designed for the material itself. It is clear and easy to implement for those skilled in the art, so it will not be described in detail here.

[0053] The above description is only a preferred embodiment of the present utility model patent and does not constitute a limitation of the present utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model patent shall be included in the protection scope of the present utility model patent.
