Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation felt processing, in particular to a composite sound insulation felt seam crimping device. Background Art

[0002] In many fields such as architectural acoustics and industrial noise control, the application of composite sound insulation felt is becoming more and more extensive. It plays a key role in reducing noise transmission and improving the acoustic environment, and the seam crimping process in its production process is crucial.

[0003] In terms of crimping, most devices use only single-sided heating or no-heat mechanical crimping. This method makes it difficult to fully fuse the two layers of the sound insulation felt, resulting in a loose crimp and affecting the overall performance of the sound insulation felt. Inadequately crimped areas may delaminate, allowing sound to easily penetrate and reducing the sound insulation effect. During the cooling process, traditional devices often lack effective cooling measures or cool too slowly, resulting in a long curing time for the crimped sound insulation felt. During this period, it is susceptible to external factors such as dust contamination and deformation caused by minor collisions, which also affect the stability of the crimping and product quality. To this end, we propose a composite sound insulation felt seam crimping device. Utility Model Content

[0007] Preferably, a plurality of supporting legs are installed on the bottom surface of the crimping table.

[0008] Preferably, the telescopic member is specifically a first electric push rod, the outer rod of the first electric push rod is fixedly mounted on the bottom surface of the mounting plate, the inner rod of the first electric push rod moves through the mounting plate, and the lifting and pressing plate is fixed to one end of the inner rod of the mounting plate.

[0011] Preferably, the cooling assembly includes a support rod and a heat dissipation fan, the support rod is installed on the front and rear sides of the through slot, and the heat dissipation fan is installed at one end of the support rod.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This composite sound insulation felt seam crimping device controls the lifting and lowering plates to press down and limit the sound insulation felt. Then, the switch of the second electric push rod is turned on, driving the connecting plate and the heating plate to move. The upper heating plate moves downward through the perforation and contacts the top surface of the sound insulation felt connection part. The lower heating plate moves upward through the perforation and contacts the bottom surface of the sound insulation felt connection part. The built-in heating wires of the two heating platens heat the sound insulation felt, and the two heating platens press the sound insulation felt connection part to complete the crimping work of the two sound insulation felts.

A through hole 7 corresponding to the through slot 3 is opened in the middle of the surface of the lifting and pressing plate 6, and a second electric push rod 8 is installed on the top surface of the lifting and pressing plate 6 and the bottom surface of the crimping platform 1;

[0022] A connecting plate 9 is installed at one end of the inner rod of the second electric push rod 8, a heating pressing plate 10 is fixedly installed on one side of the connecting plate 9, and a cooling component is installed inside the through groove 3.

[0023] Specifically, two heating press plates 10 are passed through the through-holes 7 and the through-grooves 3 respectively to press the connection parts of the sound insulation felt. The heating press plates 10 heat the connection parts to improve the pressing efficiency, and the cooling assembly can reduce the curing time after the pressing is completed.

[0024] Among them: the telescopic part is specifically the first electric push rod 5, the outer rod of the first electric push rod 5 is fixedly mounted on the bottom surface of the mounting plate 4, the inner rod of the first electric push rod 5 moves through the mounting plate 4, the lifting and pressing plate 6 is fixed to one end of the inner rod of the mounting plate 4, and turning on the switch of the first electric push rod 5 can drive the lifting and pressing plate 6 to rise and fall, which is convenient for controlling the lifting and pressing plate 6 to limit the two sound insulation felts.

[0025] Among them: the vertical positions of the two heating platens 10 correspond to the groove 3 and the through hole 7, the width of the heating platens 10 is smaller than the width of the through hole 7 and the groove 3, the upper heating platen 10 can pass through the through hole 7, and the lower heating platen 10 can pass through the groove 3.

[0026] The heating plate 10 is internally installed with a heating wire for heating the heating plate 10 . By energizing the heating wire, the heating plate 10 is heated, thereby heating the composite sound insulation felt during the crimping process.

[0027] Among them: the cooling assembly includes a support rod 11 and a heat dissipation fan 12. The support rod 11 is installed on the front and rear sides of the through slot 3. The heat dissipation fan 12 is installed at one end of the support rod 11. When the heat dissipation fan 12 is turned on, air can be blown to the connection parts of the two sound insulation felts for cooling.

[0028] Working principle: The utility model is a composite sound insulation felt seam crimping device. When in use, the first electric push rod 5 is controlled to open, so that the lifting and pressing plates 6 move upward away from the top surface of the crimping platform 1, and the two composite sound insulation felts are placed on the top surface of the crimping platform 1, and their connecting parts can be docked at the corresponding positions of the through-grooves 3. The lifting and pressing plates 6 are controlled to press down to limit the sound insulation felts. Thereafter, the switch of the second electric push rod 8 is turned on to drive the connecting plate 9 and the heating plate 10 to move. The upper heating plate 10 moves downward through the through-hole 7 and contacts the top surface of the connecting part of the sound insulation felt. The lower heating plate 10 moves upward through the through-grooves 3 and contacts the bottom surface of the connecting part of the sound insulation felt. The built-in heating wires of the two heating platens 10 heat the sound insulation felt, and the two heating platens 10 press the connecting part of the sound insulation felt to complete the crimping work of the two sound insulation felts. The crimping efficiency of the sound insulation felts is improved by double-sided heating.

[0029] Thereafter, the two heating press plates 10 are controlled to be away from the connection portion of the sound insulation felt, and the switch of the heat dissipation fan 12 is turned on, so that the heat dissipation fan 12 blows air toward the connection portion of the sound insulation felt. Since the heat dissipation fan 12 is installed on the inner side of the through groove 3 and the upper part of the heat dissipation fan 12 protrudes a certain height from the top surface of the press-bonding table 1, the heat dissipation fan 12 can simultaneously take into account the top and bottom surfaces of the connection portion of the sound insulation felt when blowing air, thereby quickly cooling it and reducing the curing time of the sound insulation felt.
