Description

Technical Field

[0001] This utility model relates to the technical field of sound insulation material processing equipment, specifically a double-roller gluing machine for sound insulation cotton composite processing. Background Technology

[0002] Sound insulation cotton primarily absorbs sound wave energy through its porous structure, converting sound energy into heat energy, thereby reducing sound reflection and propagation. It differs from "sound insulation materials" (such as soundproofing panels), which focus more on blocking sound transmission, while sound insulation cotton primarily absorbs sound.

[0003] Currently, patent number "201521003239.0" discloses a sound insulation cotton gluing device with baffles, including a frame and a belt conveyor installed on the frame. Motor gearboxes are symmetrically arranged on the frame, and a driving roller, a driven roller, and a circular roller are arranged between the gearboxes. A baffle device is also provided on the frame, comprising a cylindrical slide rail and an arc-shaped stop bar. The cylindrical slide rail is laterally fixed to the frame, and the arc-shaped stop bar is fixed to the cylindrical slide rail by a mounting ring at one end. Based on existing gluing machines, this device increases the contact area with the sound insulation cotton through the cooperation of the three sets of rollers (driving roller, driven roller, and circular roller), achieving two-stage gluing. This results in more thorough and uniform gluing of the sound insulation cotton surface. Furthermore, the arc-shaped stop bar near the driving gluing roller effectively overcomes the problem of the sound insulation cotton sticking to the gluing roller after gluing.

[0004] In the existing technologies provided in the aforementioned patents, most of them currently use traditional single-roller glue applicators, which require two coats of sound insulation cotton on both sides. This is not only inefficient, but also requires manual turning of the material after applying glue to one side, which can easily lead to glue contamination or fiber damage. Utility Model Content

[0005] The purpose of this invention is to provide a double-roller gluing machine for sound insulation cotton composite processing, so as to solve the shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-roller gluing machine for sound insulation cotton composite processing, comprising a machine base, and further comprising: an upper gluing roller rotatably connected to the machine base; a lower gluing roller slidably and rotatably connected to the machine base; a first elastic element, the process of which restores elastic deformation drives the lower gluing roller to move upward so that the lower gluing roller and the upper gluing roller respectively abut against the two sides of the sound insulation cotton; a transmission assembly, used to drive the upper gluing roller and the lower gluing roller to rotate synchronously; the upper gluing roller and the lower gluing roller each have a plurality of equidistantly distributed gluing grooves, and each gluing groove has a plurality of equidistantly distributed gluing holes; a glue supply assembly, used to inject glue into each gluing hole in the upper gluing roller and the lower gluing roller so that the glue is applied to both sides of the sound insulation cotton.

[0007] Preferably, the lower adhesive roller is located directly below the adhesive roller.

[0008] Preferably, the machine base has two vertical slide grooves symmetrically arranged on both sides of the machine base, and a slide table is slidably connected in each vertical slide groove, with the lower glue-applying roller rotatably connected between the two slide tables.

[0009] Preferably, each of the first elastic elements includes a guide rod that is vertically slidably connected to the machine base. One end of the guide rod is fixedly connected to the corresponding slide table. A first spring is sleeved on the guide rod, with one end of the first spring fixedly connected to the guide rod and the other end fixedly connected to the machine base.

[0010] Preferably, a locking element is provided between one of the guide rods and the machine base. The locking element includes a storage cavity formed on the guide rod, a locking rod slidably connected in the storage cavity, and a second spring provided in the storage cavity. One end of the second spring is fixedly connected in the storage cavity, and the other end is fixedly connected to the locking rod. A wedge block is fixedly connected to the locking rod, and the wedge surface of the wedge block is arranged facing upward. A locking hole that is fixedly connected to the machine base and engages with the locking rod is inserted into it.

[0011] Preferably, the transmission assembly includes a first bevel gear coaxially fixedly connected to the upper glue-coating roller, a second bevel gear coaxially fixedly connected to the lower glue-coating roller, a telescopic transmission rod provided on the machine base, a third bevel gear meshing with the first bevel gear being coaxially fixedly connected to one end of the telescopic transmission rod, and a fourth bevel gear meshing with the second bevel gear being fixedly connected to the other end of the telescopic transmission rod.

[0012] Preferably, the telescopic transmission rod includes a sleeve rotatably connected to the machine base and a slide rod slidably connected inside the sleeve. A limit strip is fixedly connected to the slide rod, and a limit groove is provided inside the sleeve to slide with the limit strip.

[0013] Preferably, an extension frame is fixedly connected to the two slides, and a rotating sleeve is rotatably connected to the extension frame, with the rotating sleeve slidably connected to the slide rod.

[0014] Preferably, the glue supply assembly includes two glue tubes fixedly connected to the machine base. The two glue tubes are located inside the upper glue coating roller and the lower glue coating roller, respectively, and each glue tube has a glue delivery channel. The two glue tubes are connected to the main pipeline through a three-way pump valve, and one end of the main pipeline is connected to a glue supply tank.

[0015] Preferably, the openings of the two adhesive delivery channels face the two sides of the sound insulation cotton, respectively.

[0016] In the above technical solution, the present invention provides a double-roller glue applicator for sound insulation cotton composite processing. When the upper glue applicator rotates, the lower glue applicator can be driven to rotate synchronously in the opposite direction under the cooperation of the first bevel gear, the second bevel gear, the third bevel gear, the fourth bevel gear and the telescopic transmission rod. With the cooperation of the subsequent glue supply component, the upper glue applicator and the lower glue applicator can simultaneously apply glue to both sides of the sound insulation cotton.

[0017] In summary, when the thickness of the sound insulation cotton is different, the cooperation between the first spring in the first elastic element and the guide rod allows the upper and lower glue-applying rollers to be adapted to sound insulation cotton of different thicknesses, thereby completing the glue application work on both sides of the sound insulation cotton.

[0018] Furthermore, when the gap between the upper and lower glue-coating rollers changes, the slide rod in the telescopic transmission rod will slide vertically along the corresponding slide table. Due to the cooperation of the limiting strip and the limiting groove, the slide rod can still rotate with the sleeve after sliding relative to the sleeve, thus not affecting the synchronous rotation of the upper and lower glue-coating rollers.

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-7 This utility model provides a double-roller gluing machine for sound insulation cotton composite processing, including a machine base 1, an upper gluing roller 2, a lower gluing roller 3, a first elastic element 4, a transmission assembly 5, and a glue supply assembly 6. The upper gluing roller 2 is rotatably connected to the machine base 1; the lower gluing roller 3 is slidably and rotatably connected to the machine base 1; the process of the first elastic element 4 restoring its elastic deformation drives the lower gluing roller 3 to move upward so that the lower gluing roller 3 and the upper gluing roller 2 respectively abut against the two sides of the sound insulation cotton; the transmission assembly 5 is used to drive the upper gluing roller 2 and the lower gluing roller 3 to rotate synchronously; the upper gluing roller 2 and the lower gluing roller 3 each have a plurality of equidistantly distributed gluing grooves 11, and each gluing groove 11 has a plurality of equidistantly distributed gluing holes 12; the glue supply assembly 6 is used to inject glue into each gluing hole 12 in the upper gluing roller 2 and the lower gluing roller 3 so that the glue is applied to both sides of the sound insulation cotton.

[0031] The lower glue-applying roller 3 is located directly below the glue-applying roller.

[0032] The machine base 1 has two vertical slide grooves 7 symmetrically arranged on both sides of the machine base 1. Each vertical slide groove 7 is slidably connected to a slide table 8, and the lower glue-applying roller 3 is rotatably connected between the two slide tables 8.

[0033] Each first elastic element 4 includes a guide rod 41 that is vertically slidably connected to the machine base 1. One end of the guide rod 41 is fixedly connected to the corresponding slide table 8. A first spring 42 is sleeved on the guide rod 41. One end of the first spring 42 is fixedly connected to the guide rod 41, and the other end is fixedly connected to the machine base 1.

[0034] One of the guide rods 41 is provided with a locking device between it and the machine base 1. The locking device includes a storage cavity 43 opened on the guide rod 41. A locking rod 44 is slidably connected in the storage cavity 43. A second spring 45 is provided in the storage cavity 43. One end of the second spring 45 is fixedly connected in the storage cavity 43, and the other end is fixedly connected to the locking rod 44. A wedge block 46 is fixedly connected to the locking rod 44, and the wedge surface of the wedge block 46 is arranged facing upward. A locking hole 47 that is fixedly connected to the machine base 1 and engages with the locking rod 44.

[0035] The transmission assembly 5 includes a first bevel gear 51 coaxially fixedly connected to the upper glue-coating roller 2, a second bevel gear 52 coaxially fixedly connected to the lower glue-coating roller, and a telescopic transmission rod on the machine base 1. One end of the telescopic transmission rod is coaxially fixedly connected to a third bevel gear 53 that meshes with the first bevel gear 51, and the other end is fixedly connected to a fourth bevel gear 54 that meshes with the second bevel gear 52.

[0036] The telescopic transmission rod includes a sleeve 55 rotatably connected to the machine base 1 and a slide rod 56 slidably connected inside the sleeve 55. A limit strip 57 is fixedly connected to the slide rod 56, and a limit groove 58 that slides with the limit strip 57 is provided inside the sleeve 55.

[0037] Among them, an extension frame 9 is fixedly connected to the two slides 8, and a rotating sleeve 10 is rotatably connected to the extension frame 9, and the rotating sleeve 10 is slidably connected to the slide rod 56.

[0038] It should be noted that this solution also includes a drive motor (not shown in the figure) using existing technology, and the output shaft of the drive motor is coaxially and fixedly connected to the first bevel gear 51. However, when the drive motor is working, the output shaft of the drive motor can drive the first bevel gear 51, which is fixedly connected to the upper glue-coating roller 2, to rotate.

[0039] Specifically, when the upper glue-applying roller 2 rotates, the lower glue-applying roller 3 can be driven to rotate synchronously in the opposite direction by the cooperation of the first bevel gear 51, the second bevel gear 52, the third bevel gear 53, the fourth bevel gear 54 and the telescopic transmission rod. With the cooperation of the subsequent glue supply component 6, the upper glue-applying roller 2 and the lower glue-applying roller 3 can apply glue to both sides of the sound insulation cotton simultaneously.

[0040] In summary, when the thickness of the sound insulation cotton is different, the cooperation between the first spring 42 in the first elastic element 4 and the guide rod 41 allows the upper glue roller 2 and the lower glue roller 3 to be adapted to sound insulation cotton of different thicknesses, thereby completing the glue application work on both sides of the sound insulation cotton.

[0041] Furthermore, when the gap between the upper glue-applying roller 2 and the lower glue-applying roller 3 changes, the slide rod 56 in the telescopic transmission rod will slide vertically with the corresponding slide table 8. Due to the cooperation of the limiting strip 57 and the limiting groove 58, the slide rod 56 can still rotate with the sleeve 55 after sliding relative to the sleeve 55, thus not affecting the synchronous rotation of the upper glue-applying roller 2 and the lower glue-applying roller 3.

[0042] It should be noted that the restoring force of the first spring 42 is much greater than that of the second spring 45, and a pressure rod is fixedly connected to the guide rod 41. Therefore, before applying the adhesive, to facilitate guiding it into the gap between the upper adhesive roller 2 and the lower adhesive roller 3, the pressure rod can be manually pressed until the locking rod 44 aligns with the locking hole 47. Then, driven by the restoring elastic force of the second spring 45, the locking hole 47 is inserted into the locking hole 47, and the wedge block 46 extends out of the locking hole 47. When unlocking, simply press the wedge block 46 to slide it into the locking hole 47. Driven by the restoring elastic force of the first spring 42, and with the wedge surface of the wedge block 46 abutting against the top of the locking hole 47, the guide rod 41 moves upward, thereby completing the unlocking between the guide rod 41 and the machine 1.

[0043] The glue supply assembly 6 includes two glue tubes 61 fixedly connected to the machine base 1. The two glue tubes 61 are located in the upper glue coating roller 2 and the lower glue coating roller 3 respectively, and each glue tube 61 has a glue delivery channel 62. The two glue tubes 61 are connected to the main pipeline through a three-way pump valve 63. One end of the main pipeline is connected to a glue supply tank 64.

[0044] The openings of the two adhesive delivery channels 62 face the two sides of the sound insulation cotton, respectively.

[0045] Specifically, when the three-way pump valve 63 is working, the glue supply assembly 6 can deliver the glue in the glue tank 64 to the glue tube 61 in the upper glue roller 2 and the lower glue roller 3. Then, it is delivered to the glue application holes 12 in the upper glue roller 2 and the lower glue roller 3 through the glue delivery channel 62. It should be noted that since the opening direction of the two glue delivery channels 62 is respectively facing the two sides of the sound insulation cotton, the glue application holes 12 of the upper glue roller 2 and the lower glue roller 3 are just aligned with the opening of the glue delivery channel 62. Only then will the glue be applied to both sides of the sound insulation cotton. This effectively avoids the situation where each glue application hole 12 has a certain amount of glue, causing the glue to splash outwards centrifugally during the rotation of the upper glue roller 2 and the lower glue roller 3.

[0046] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
