Description

Technical Field

[0001] The utility model relates to the technical field of rolling presses, and particularly relates to a sound insulation cotton rolling press. Background Art

[0002] During the automobile production process, rolling presses are often used. For example, when installing sound insulation cotton, the sound insulation cotton needs to be pasted on the installation surface, and then the rolling press is used to press the sound insulation cotton. However, the existing sound insulation cotton rolling presses usually adopt cylindrical rollers. When rolling, the surface of the sound insulation cotton can be pressed into a flat surface. However, the sound insulation effect of the flat-shaped sound insulation cotton is not ideal. In addition, this kind of sound insulation cotton rolling press can only be applied to the case where the installation surface of the sound insulation cotton is flat. When there is an arc surface on the installation surface, this sound insulation cotton rolling press cannot press the sound insulation cotton well on the arc surface. At this time, manual pressing is required, which greatly reduces the rolling efficiency of the sound insulation cotton. Content of the Utility Model

[0003] The utility model aims to at least solve one of the technical problems existing in the prior art.

Those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0035] Refer to Figures 1 to 9 , an embodiment of the present utility model provides a sound insulation cotton roller press, which includes a handle 100, a fixing frame 200, and a roller assembly. The fixing frame 200 is provided at one end of the handle 100. The roller assembly includes a first roller 300 and a second roller 310, and both the first roller 300 and the second roller 310 can be detachably installed on the fixing frame 200. Among them, the outer peripheral wall of the first roller 300 is parallel to the central axis of the first roller 300, and at least two spaced-apart protruding portions 301 are provided on the outer peripheral wall of the first roller 300; the outer peripheral wall of the second roller 310 is an arc-shaped concave surface 311 with an opening facing away from the central axis of the second roller 310.

[0036] In the sound insulation cotton roller of the embodiment of the present utility model, when the installation surface is a plane, the first roller 300 can be installed on the fixing frame 200. The outer peripheral wall of the first roller 300 is parallel to the central axis of the first roller 300, and at least two spaced convex portions 301 are provided on the outer peripheral wall of the first roller 300. Thus, the first roller 300 can roll on the surface of the sound insulation cotton to form a concave-convex surface, so as to form multiple reflection surfaces and refraction surfaces, and further effectively reduce the transmission of noise and improve the sound insulation effect of the sound insulation cotton. When there is an arc surface on the installation surface of the sound insulation cotton, the first roller 300 can be removed from the fixing frame 200, and the second roller 310 can be installed on the fixing frame 200. Since the outer peripheral wall of the second roller 310 is an arc concave surface 311 with an opening facing away from the central axis of the second roller 310, it can be adapted to the arc surface, which is not only beneficial to better press the sound insulation cotton onto the arc surface, making the fit between the sound insulation cotton and the arc surface more firm, but also beneficial to improve the rolling efficiency of the sound insulation cotton compared with manual pressing. It can be seen that the sound insulation cotton roller of the embodiment of the present utility model is configured with the first roller 300 and the second roller 310. Therefore, the roller on the fixing frame 200 can be replaced according to specific rolling requirements, which is not only beneficial to improving the sound insulation effect of the sound insulation cotton, but also applicable to the case where there is an arc surface on the installation surface.

[0037] In addition, in the sound insulation cotton roller of the embodiment of the present utility model, both the first roller 300 and the second roller 310 can be detachably installed on the fixing frame 200. Therefore, there is no need to separately set two independent sound insulation cotton rollers. Only different rollers need to be replaced according to needs, which is convenient to use, greatly improves the applicability of the fixing frame 200, and is also beneficial to reducing the processing cost of the sound insulation cotton rolling process in the automobile production process compared with producing two independent sound insulation cotton rollers for the first roller 300 and the second roller 310.

[0038] In some embodiments, the roller assembly includes a third roller that can be detachably installed on the fixing frame 200, and the outer peripheral wall of the third roller is parallel to the central axis of the first roller 300.

[0039] By adopting the above structure, the roller assembly further includes a third roller. The outer peripheral wall of the third roller is parallel to the central axis of the first roller 300, that is, the third roller is cylindrical. Thus, when the installation surface of the sound insulation cotton is a plane, the operator can first install the third roller onto the fixing frame 200, pre-press the sound insulation cotton through the third roller, and then remove the third roller and install the first roller 300 onto the fixing frame 200. At this time, the first roller 300 can be used to roll on the surface of the sound insulation cotton to form a concave-convex surface, so as to form multiple reflecting surfaces and refracting surfaces, and further effectively reduce the transmission of noise, which is beneficial to improving the sound insulation effect of the sound insulation cotton. During the above rolling process, using the third roller to pre-press the sound insulation cotton before using the first roller 300 can not only make the sound insulation cotton fit more firmly with the installation surface, but also make the surface of the sound insulation cotton relatively flat, which is beneficial to the subsequent rolling of the first roller 300 on the sound insulation cotton.

[0040] Referring to Figures 3 to 5 , in some embodiments, in the first roller 300, at least two convex portions 301 are arranged at intervals along the axial direction of the first roller 300.

[0041] By adopting the above structure, when using the first roller 300 to roll the sound insulation cotton, at least two pits can be printed on the surface of the sound insulation cotton at one time, so as to form a concave-convex surface on the surface of the sound insulation cotton, and further increase the number of pits formed on the surface of the sound insulation cotton during the rolling process of the first roller 300, thereby further improving the sound insulation effect of the sound insulation cotton.

[0042] Referring to Figures 3 to 5 , in some embodiments, in the first roller 300, at least two convex portions 301 are arranged at intervals along the circumferential direction of the first roller 300.

[0043] By adopting the above structure, when using the first roller 300 to roll the sound insulation cotton, at least two pits can be continuously printed on the surface of the sound insulation cotton, so as to increase the number of pits formed on the surface of the sound insulation cotton when the first roller 300 rolls one week, thereby further improving the sound insulation effect of the sound insulation cotton.

[0044] It can be understood that in the first roller 300, at least two convex portions 301 can be arranged only at intervals along the axial direction of the first roller 300, or at least two convex portions 301 can be arranged only at intervals along the circumferential direction of the first roller 300. Or, in some embodiments, the number of convex portions 301 is at least three. At this time, at least two convex portions 301 can be arranged at intervals along the axial direction of the first roller 300, and at the same time, at least two convex portions 301 can be arranged at intervals along the circumferential direction of the first roller 300. The present invention does not make specific limitations on this. For example, referring to Figure 4 and Figure 5, in some embodiments, every five convex portions 301 are arranged at intervals in sequence along the axial direction of the first roller 300 and form a column of convex groups. A total of eight columns of convex groups are provided on the outer peripheral wall of the first roller 300, and the eight columns of convex groups are arranged at intervals along the circumferential direction of the first roller 300. This structure greatly increases the number of convex portions 301 on the outer peripheral wall of the first roller 300, and thus greatly increases the number of pits formed when the first roller 300 rolls on the sound insulation cotton for one week. Thereby, not only the formation efficiency of the pits on the surface of the sound insulation cotton is improved, but also more reflecting surfaces and refracting surfaces can be formed on the surface of the sound insulation cotton, greatly improving the sound insulation effect of the sound insulation cotton.

[0045] Referring to Figures 3 to 5 , in some embodiments, in the first roller 300, the outer peripheral wall of the convex portion 301 has an arc-shaped convex surface 302.

[0046] By adopting the above structure, setting the arc-shaped convex surface 302 on the outer peripheral wall of the convex portion 301 can reduce the risk of scratching and damaging the surface of the sound insulation cotton due to the relatively sharp edge of the convex portion 301, thus being beneficial to protecting the surface of the sound insulation cotton.

[0047] Referring to Figures 3 to 5 , in some embodiments, in the axial direction of the first roller 300, the projection of the arc-shaped convex surface 302 is arc-shaped.

[0048] By adopting the above structure, the arc-shaped convex surface 302 is arranged in an arc-shaped bend along the circumferential direction of the first roller 300 and extends linearly along the axial direction of the first roller 300. Thereby, it can facilitate the production and processing of the convex portion 301, and can facilitate the formation of arc-shaped pits on the surface of the sound insulation cotton, making the inner wall of the pits on the surface of the sound insulation cotton smoother, being beneficial to reducing the transmission of noise and improving the sound insulation performance of the sound insulation cotton.

[0049] It can be understood that the outer peripheral wall of the convex portion 301 is the arc-shaped convex surface 302. In addition to setting the projection of the arc-shaped convex surface 302 to be arc-shaped in the axial direction of the first roller 300, that is, making the arc-shaped convex surface 302 bend in an arc along the circumferential direction of the first roller 300, in some embodiments, the projection of the arc-shaped convex surface 302 can also be set to be arc-shaped in the radial direction of the first roller 300, that is, making the arc-shaped convex surface 302 bend in an arc in the axial direction of the first roller 300. Thereby, arc-shaped pits can also be rolled and formed on the surface of the sound insulation cotton. Of course, in addition to this, the entire outer peripheral wall of the convex portion 301 can also be set as the arc-shaped convex surface 302, and the present utility model does not make specific limitations thereto.

[0050] In some embodiments, both the first roller 300 and the second roller 310 are made of nylon.

[0051] By adopting the above structure, both the first roller 300 and the second roller 310 are made of nylon parts, which can not only stably fit the sound insulation cotton with the installation surface during the rolling process, but also protect the surface of the sound insulation cotton to prevent the edges of the first roller 300 and the second roller 310 from scratching the surface of the sound insulation cotton.

[0052] Referring to Figures 6 to 8 , in some embodiments, the fixing frame 200 has a first mounting portion 210 and a second mounting portion 220 arranged oppositely. The first mounting portion 210 and the second mounting portion 220 are spaced apart to form a mounting space. The first mounting portion 210 is provided with a first mounting hole 211, and the second mounting portion 220 is provided with a second mounting hole coaxially arranged with the first mounting hole 211. Both the first roller 300 and the second roller 310 are provided with third mounting holes 320. A first fastener 230 is further included. When the first roller 300 or the second roller 310 is placed between the first mounting portion 210 and the second mounting portion 220, the first fastener 230 can sequentially pass through the first mounting hole 211, the third mounting hole 320, and the second mounting hole.

[0053] By adopting the above structure, during installation, only the roller needs to be placed between the first mounting portion 210 and the second mounting portion 220, and then the first fastener 230 is sequentially passed through the first mounting hole 211, the second mounting hole, and the third mounting hole 320. The structure is simple, convenient for installation and disassembly, and thus makes the replacement of the first roller 300 and the second roller 310 more convenient and fast.

[0054] Referring to Figures 6 to 8 , in some embodiments, one end of the first fastener 230 is provided with a first pressing portion 231 that can abut against the outer side wall of the first mounting portion 210, and the other end of the first fastener 230 is provided with a second pressing portion 232 that can abut against the outer side wall of the second mounting portion 220.

[0055] By adopting the above structure, when the first fastener 230 is inserted into the first mounting hole 211, the second mounting hole, and the third mounting hole 320, the first pressing portion 231 can abut against the outer side wall of the first mounting portion 210, and the second pressing portion 232 can abut against the outer side wall of the second mounting portion 220. Thereby, the installation of the first roller 300 and the second roller 310 can be made more firm and stable, which is beneficial to the normal progress of the sound insulation cotton rolling operation.

[0056] It can be understood that referring to Figures 6 to 8, the first pressing part 231 is integrally provided at one end of the first fastener 230, and the second pressing part 232 is detachably installed at the other end of the first fastener 230. Thus, when installing, the roller can be placed between the first installation part 210 and the second installation part 220, the first fastener 230 is sequentially inserted through the first installation hole 211, the second installation hole and the third installation hole 320, and the first pressing part 231 is made to abut against the outer side wall of the first installation part 210. Then, the second pressing part 232 is installed on the first fastener 230 and abuts against the outer side wall of the second installation part 220. This not only makes the installation of the first roller 300 and the second roller 310 more firm and stable, but also makes the installation and disassembly of the first roller 300 and the second roller 310 more rapid and convenient. It can be understood that the first fastener 230 can specifically adopt a bolt structure, the first pressing part 231 is the nut at the end of the bolt, and the second pressing part 232 can specifically adopt a nut matching the bolt structure. Thus, the structure of the first fastener 230 is simple and the material is convenient to obtain, greatly reducing the production cost of the sound insulation cotton roller press.

[0057] Of course, in addition to integrally setting the first pressing part 231 at one end of the first fastener 230 and detachably installing the second pressing part 232 at the other end of the first fastener 230, in some embodiments, the second pressing part 232 can also be integrally provided at one end of the first fastener 230, the first pressing part 231 can be detachably installed at the other end of the first fastener 230, or the first pressing part 231 and the second pressing part 232 can be respectively detachably installed at both ends of the first fastener 230. The present utility model does not make specific limitations in this regard.

[0058] Refer to Figures 6 to 9 , in some embodiments, a limiting groove 110 is formed on the end face of the handle 100, the fixing frame 200 is embedded in the limiting groove 110, and the fixing frame 200 and the bottom wall of the limiting groove 110 are detachably connected by a second fastener 120.

[0059] By adopting the above structure, the limiting groove 110 is formed on the end face of the handle 100. This not only facilitates the positioning and installation of the fixing frame 200, making the installation of the fixing frame 200 more convenient, but also the setting of the limiting groove 110 can limit the fixing frame 200, preventing the fixing frame 200 from rotating relative to the handle 100 during the process of rolling the sound insulation cotton by the sound insulation cotton roller press, thus being beneficial to the normal progress of the sound insulation cotton rolling operation.

[0060] Refer to Figures 6 to 9, the fixing bracket 200 is detachably connected to the bottom wall of the limiting groove 110 through a second fastener 120. Specifically, the fixing bracket 200 is provided with a fourth mounting hole 240, and the bottom wall of the limiting groove 110 is provided with a fifth mounting hole 130. The second fastener 120 can sequentially pass through the fourth mounting hole 240 and the fifth mounting hole 130, so as to realize the installation connection between the fixing bracket 200 and the handle 100.

[0061] It can be understood that with reference to Figures 6 to 9 , the fourth mounting hole 240 on the fixing bracket 200 is specifically a stepped hole, so that the second fastener 120 can be received in the large hole of the stepped hole, thereby reducing the risk that the end of the second fastener 120 protrudes from the fixing bracket 200 and collides with the first roller 300 or the second roller 310. At the same time, it can also increase the disassembly difficulty of the second fastener 120 and reduce the risk of accidental detachment of the second fastener 120 from the fourth mounting hole 240 and the fifth mounting hole 130.

[0062] It can be understood that the second fastener 120 can specifically be a bolt or a stud, etc., and the present utility model does not make specific limitations thereto.

[0063] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge possessed by those of ordinary skill in the art.
