Description

Technical Field

[0001] This utility model mainly relates to the technical field of adhesive coating devices, specifically a bonding processing device for the production of composite sound insulation boards. Background Technology

[0002] Composite sound insulation board bonding and processing equipment typically employs automated or semi-automated production methods, significantly improving production efficiency. During production, this equipment can precisely control parameters such as the size, thickness, and weight of the sound insulation boards, ensuring product quality stability and consistency. Furthermore, some equipment is equipped with advanced detection systems that can monitor the sound insulation performance of the products in real time, promptly identifying and resolving problems. However, existing composite sound insulation board bonding and processing equipment usually only allows bonding before drilling, otherwise the sound insulation holes will become blocked. On-site bonding requires manual operation, which is time-consuming and labor-intensive, as it necessitates bonding to composite sound insulation boards with existing holes. Therefore, a device capable of bonding composite sound insulation boards after drilling is needed.

[0003] According to application number 202022144148.6, a gluing device for producing and processing sound insulation panels includes a support frame, a transmission belt wrapped around the outer surface of the support frame, a material to be processed placed on the upper surface of the transmission belt, a support rod mounted on one end side surface of the support frame, an extension arm fitted onto the side surface of the support rod, an adjusting rotating frame mounted on the top of the support rod, and one end of the adjusting rotating frame connected to the extension arm by a threaded connection.

[0004] The above-mentioned material is discharged through the glue pipe and then through the porous rubber strip, and guided to the upper surface of the board to be processed by the liquid guiding brush to complete the glue application; it can achieve spraying processing of boards of different specifications, but it is easy to apply glue to the sound insulation holes of the sound insulation board, causing blockage. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a bonding and processing device for the production of composite sound insulation panels, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A bonding processing device for producing composite sound insulation panels includes a conveyor belt, two first support frames located on both sides of the middle section of the conveyor belt, two sets of second support frames located on both sides of the top of one end of the conveyor belt, a mixing tank located in the middle of the first support frames, an H-shaped connecting rod located in the middle of the second support frames, a plurality of extrusion cylinders arranged in a linear matrix below the H-shaped connecting rod, a piston component located inside the extrusion cylinders, and a glue guiding component connecting one end of the extrusion cylinders to the bottom of the mixing tank.

[0008] Preferably, the conveyor belt includes multiple limiting wheels located on both sides of the interior, and a laser monitoring device located at the top of the end of the conveyor belt away from the second support frame.

[0009] Preferably, the second support frame includes a lower support, a plurality of telescopic cylinders disposed at the top of the lower support, an upper support disposed at the top actuating end of the telescopic cylinders, and a mounting frame disposed in the middle of the two lower supports.

[0010] Preferably, the mixing tank includes an internal stirring rod, a first reducer disposed on one side of the first support frame and with its output end connected to the central shaft of the stirring rod, and a first motor with its actuating end connected to the input end of the first reducer. The H-shaped connecting rod includes a second reducer disposed on one side of the second support frame and with its output end connected to the central shaft of the H-shaped connecting rod, and a second motor with its actuating end connected to the input end of the second reducer.

[0011] Preferably, the extrusion cylinder includes a star-shaped nozzle at the bottom output end, a strip-shaped through groove near one end of the extrusion cylinder, and two mounting steel plates on both sides connecting the mounting frame.

[0012] Preferably, the piston component includes a long piston disposed inside the extrusion cylinder, one end of which is hinged to the top of the long piston, and the other end of which is rotatably connected to a piston rod on the H-shaped connecting rod.

[0013] Preferably, the adhesive guiding component includes a connecting pipe located at the bottom of the mixing tank, a three-way valve located at the other end of the connecting pipe, a check valve located at one output port of the three-way valve, and a deformed pipe connecting the other end of the check valve to the strip-shaped through groove.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention employs a star-shaped nozzle for adhesive application, spreading the adhesive in a star-shaped pattern to the central area of ​​the circular soundproofing holes in the composite sound insulation board. This effectively avoids the problem of clogging the circular soundproofing holes that is common with conventional adhesive application methods. Simultaneously, a laser monitoring device can identify areas unsuitable for adhesive application and, through a three-way valve, control the extrusion cylinder at the corresponding location to only spray air without applying adhesive, further preventing clogging of the soundproofing holes.

[0016] High-frequency adhesive application and flexible adjustment: The second motor drives the H-shaped connecting rod to rotate via the second reducer, which in turn drives the piston rod to reciprocate and press the long piston inside the extrusion cylinder, achieving high-frequency adhesive application. Simultaneously, the spacing data of the circular soundproofing holes identified by the laser monitor can be converted into the rotational speed of the second motor, adjusting the operating cycle of the long piston and the adhesive spraying frequency to accommodate circular soundproofing holes with different spacings. Furthermore, the extension and retraction of the telescopic cylinder can also change the amount of adhesive sprayed, compensating for the change in the central star-shaped area caused by the different spacing of the circular soundproofing holes.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3, 4, 5, and 6, a bonding processing device for producing composite sound insulation panels includes a conveyor belt 10, two first support frames 11 located on both sides of the middle of the conveyor belt 10, two sets of second support frames 12 located on both sides of the top of one end of the conveyor belt 10, a mixing tank 13 located in the middle of the first support frames 11, an H-shaped connecting rod 14 located in the middle of the second support frames 12, a plurality of extrusion cylinders 15 arranged in a linear matrix below the H-shaped connecting rod 14, a piston component 16 located inside the extrusion cylinders 15, and a glue guiding component 17 connecting one end of the extrusion cylinders 15 to the bottom of the mixing tank 13; the mixing tank 13 includes an internal stirring rod 131, and an output end connected to the stirring rod 131 located on one side of one of the first support frames 11. The shaft includes a first reducer 132, and an actuator connected to the input end of the first reducer 132; the H-shaped connecting rod 14 includes a second reducer 141 located on one side of the second support frame 12 and connected to the central shaft of the H-shaped connecting rod 14 at its output end, and a second motor 142 connected to the input end of the second reducer 141 at its actuator end; the extrusion cylinder 15 includes a star-shaped nozzle 151 located at the bottom output end, a strip-shaped through groove 152 located near one end of the extrusion cylinder 15, and two mounting steel plates 153 located on both sides and connected to the mounting bracket 124; the piston component 16 includes a long piston 161 located inside the extrusion cylinder 15, one end of which is hinged to the top of the long piston 161, and the other end of which is rotatably connected to the piston rod 162 on the H-shaped connecting rod 14.

[0027] As mentioned above, during the normal adhesive application process, the composite sound insulation board has a large number of neatly arranged circular sound insulation holes, which are easily blocked by conventional adhesive application. In this embodiment, by using the star-shaped nozzle 151, the adhesive is spread in a star shape on the star-shaped area in the center of the four circular sound insulation holes when squeezed. This effectively avoids the blockage of the circular sound insulation holes when applying the adhesive to the composite sound insulation board. The mixing tank 13 has an input pipe at the top. When new adhesive is poured in, the first reducer 132 can convert the rotational power output by the first motor 133 into a large torque rotational power, which drives the mixing rod 131 to stir the adhesive in the mixing tank 13 and prevent the adhesive from solidifying. The second motor 142 drives the second reducer 141 to output a large torque rotational power to drive the H-shaped connecting rod 14 to rotate, which in turn drives each piston rod 162 to reciprocate to lift and press the long piston 161 inside the extrusion cylinder 15. This allows the adhesive to be absorbed from the adhesive guiding component 17 at high frequency and sprayed onto the composite sound insulation board through the star-shaped nozzle 151.

[0028] Please refer to the attached document carefully. Figure 1 , 2As shown in Figure 3, the conveyor belt 10 includes multiple limiting wheels 101 located on both sides of the interior, and a laser monitor 102 located at the top of the end of the conveyor belt 10 away from the second support frame 12; the second support frame 12 includes a lower support 121, multiple telescopic cylinders 122 located at the top of the interior of the lower support 121, an upper support 123 located at the top execution end of the telescopic cylinders 122, and a mounting frame 124 located in the middle of the two lower supports 121; the adhesive guiding component 17 includes a connecting pipe 171 located at the bottom of the mixing tank 13, a three-way valve 172 located at the other end of the connecting pipe 171, a check valve 173 located at one output port of the three-way valve 172, and a deformed pipe 174 connecting the other end of the check valve 173 to the strip groove 152.

[0029] As described above, the limiting wheel 101 is used to restrict the composite sound insulation board to the middle of the conveyor belt 10 to prevent displacement that would cause the circular sound insulation holes to be blocked by glue. The laser monitor 102 is used to identify both the spacing of each row of circular sound insulation holes and the number of each row of circular sound insulation holes. The spacing of each row of circular sound insulation holes identified by the laser monitor 102 is converted into the rotation speed of the second motor 142 by the control element, thereby adjusting the running cycle of the long piston 161, thus achieving a fine adjustment of the glue spraying frequency relative to the spacing of each row of circular sound insulation holes. Correspondingly, the multiple telescopic cylinders 122 at the top of the lower bracket 121 will also change their telescopic amount accordingly. The telescopic amount of the telescopic cylinder 122 will raise or lower the entire H-shaped connecting rod 14, piston rod 162, and long piston 161 by one end from the extrusion cylinder 15. Due to the change in the blocking area of ​​the long piston 161 received by the strip groove 152 when the glue is injected, it can change the... The volume of the adhesive is varied, thereby increasing or decreasing the amount of adhesive sprayed during a single extrusion spraying process. This compensates for the change in the central star-shaped area caused by the different spacing of the circular sound insulation holes in each row. To achieve this function, the piston rod 162 and the long piston 161 must be long enough to ensure that the strip groove 152 can be completely blocked by the long piston 161 when it is compressed. Since the circular sound insulation holes on some composite sound insulation boards are not arranged in a rectangular pattern but are alternating, when the laser monitor 102 identifies that some positions are not suitable for adhesive application, the three-way valve 172 on the adhesive guiding component 17 at the corresponding position will seal the inlet of one end of the connecting pipe 171 and open the empty inlet. In this way, the extrusion cylinder 15 at the corresponding position will only spray air and not apply adhesive when the H-shaped connecting rod 14 is running synchronously with the piston, thus avoiding clogging of the circular sound insulation holes. When adhesive application is needed, the three-way valve 172 will be reset so that adhesive can be applied again.

[0030] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
