Description

Technical Field

[0001] This utility model belongs to the technical field of sound insulation cotton production equipment, and in particular relates to a sound insulation cotton embossing roller switching mechanism. Background Technology

[0002] Automotive sound insulation cotton, as the name suggests, is used for sound insulation in vehicles. The production process mainly includes raw material preparation and mixing, fiber web formation, embossing, and cutting. In automotive sound insulation cotton production, single-sided embossing is generally used. The embossed side increases the surface friction of the material, while the other side is usually smooth and flat for easy subsequent laying. In actual production, the embossing roller needs to be changed depending on the product (e.g., from dotted to striped, changing the pattern density, or using a special logo). Additionally, the appropriate embossing roller may need to be changed depending on the thickness and hardness of the sound insulation cotton.

[0003] The existing integrated sound insulation cotton production machine can only be equipped with one embossing roller at a time. Each time the embossing roller is replaced, it is necessary to manually disassemble, remove and install the required roller, which is cumbersome. In addition, the embossing roller has a certain weight, which makes the work intensity high.

[0004] To address the aforementioned issues, this application proposes a sound insulation cotton embossing roller switching mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a sound insulation cotton embossing roller switching mechanism, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a sound insulation cotton embossing roller switching mechanism, comprising a frame and an embossing roller to be switched. A crossbeam is fixed on the frame, and a first cylinder is installed at the bottom of the crossbeam. A lifting frame is installed on the first cylinder to support the embossing roller during embossing. Symmetrical upright plates are fixed on the side of the frame, and drive rollers are installed on the upright plates to cooperate with the embossing roller to emboss the sound insulation cotton. A horizontally sliding placement frame is provided on the frame via a linear guide rail, and multiple embossing rollers of different models are placed on the placement frame.

[0008] The embossing roller is fixed with a first bearing and a second bearing at both ends.

[0009] Furthermore, a horizontal plate is fixed to the top of the upright plate, an upper shaft seat is fixed to one side of the lower end of the horizontal plate, and lower shaft seats are fixed to both ends of the lifting frame. After the lower shaft seats move upward, they come into contact with the upper shaft seats and form support for the second bearing.

[0010] Furthermore, several sets of placement shaft seats are fixed at the upper end of the placement frame, and the first bearing is located in the placement shaft seats to support the embossing roller.

[0011] Furthermore, a positioning seat located above the bearing seat is fixed at the bottom of the upper bearing seat, and the positioning seat has a groove formed inside for the first bearing to enter in the vertical direction.

[0012] Furthermore, a top plate is fixed to the top of the horizontal plate for mounting the drive roller, and a motor that drives the drive roller is fixed to the side of one of the top plates.

[0013] Furthermore, a pull plate is fixed between the upper end of the side of the upright plate and the side of the frame.

[0014] Furthermore, a horizontal switching cylinder is fixedly installed on the frame, and the output end of the switching cylinder is fixedly installed to the bottom of the placement frame.

[0015] This invention has the following advantages: By placing multiple embossing rollers of different models on the placement frame, and driving them to move horizontally under the action of linear guide rail and switching cylinder, the embossing rollers on the placement frame can be lifted to the embossing station that cooperates with the drive roller under the action of the first cylinder and lifting frame. Compared with the prior art, this invention is more convenient to operate and more efficient, and can also effectively reduce the intensity of switching work.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a sound insulation cotton embossing roller switching mechanism, including a frame 1 and an embossing roller 6 to be switched. A crossbeam 11 is fixed on the frame 1 by welding or bolts. A first cylinder 2 is installed at the bottom of the crossbeam 11. The first cylinder 2 is fixed to the crossbeam 11 and its output end passes through the crossbeam 11 upward. A lifting frame 3 is fixedly installed at the output end of the first cylinder 2. The lifting frame 3 supports the bottom of the embossing roller 6 during embossing. Symmetrical upright plates 4 are welded and fixed on the side of the frame 1. A drive roller 5 is installed on the upright plate 4 to cooperate with the embossing roller 6 to emboss the sound insulation cotton. A horizontally sliding placement frame 8 is provided on the frame 1 through a linear guide rail 7. Multiple embossing rollers 6 of different models are placed on the placement frame 8.

[0030] The embossing roller 6 has a first bearing 61 and a second bearing 62 fixed at both ends.

[0031] Specifically, a horizontal plate 41 is welded and fixed to the top of the upright plate 4, and an upper shaft seat 42 is welded and fixed to one side of the lower end of the horizontal plate 41. Lower shaft seats 31 are fixed to both ends of the lifting frame 3. After the lower shaft seat 31 moves up, it fits against the upper shaft seat 42 and forms support for the second bearing 62. The lower shaft seat 31 and the upper shaft seat 42 provide support for the embossing roller 6 and also play a radial and axial limiting role to prevent displacement. The second bearing 62 ensures that the embossing roller 6 rotates smoothly. At this time, the embossing roller 6 is in the embossing working state.

[0032] Specifically, in order to avoid excessive wear on the embossing roller 6 when placed on the placement frame 8, several sets of placement bearings 81 are fixed at the upper end of the placement frame 8. The first bearing 61 is located in the placement bearing 81 to support the embossing roller 6. The placement bearing 81 does not affect the up and down movement of the embossing roller 6, but can limit the embossing roller 6 in the radial and axial directions to prevent the embossing roller 6 from slipping off the placement frame 8.

[0033] Specifically, the bottom of the upper shaft seat 42 is also fixed with a positioning seat 43 located above the shaft seat 81. The positioning seat 43 has a groove inside for the first bearing 61 to enter in the vertical direction. In this embodiment, the first bearing 61 will enter the groove of the positioning seat 43 under the upward driving action of the first cylinder 2. The groove can prevent the embossing roller 6 from moving horizontally and play a role in strengthening the stability of the embossing roller 6 during embossing.

[0034] Specifically, a top plate 44 is welded and fixed to the top of the horizontal plate 41 for the installation of the drive roller 5. A motor 51 that drives the drive roller 5 is fixed to the side of one of the top plates 44. The drive roller 5 is the active end. After the embossing roller 6 moves up to the working position, it contacts the drive roller 5. Synchronous transmission is achieved through friction between the two. It should be noted that in actual use, the width of the sound insulation cotton is less than the length of the drive roller 5 and the embossing roller 6 to leave transmission space for the drive roller 5 and the embossing roller 6, thereby ensuring the reliable operation of the embossing work.

[0035] Specifically, in order to strengthen the connection between the upright plate 4 and the frame 1, a tension plate 45 is fixed between the upper side of the upright plate 4 and the side of the frame 1 to form a triangular support, so as to ensure the structural stability of the drive roller 5 and the embossing roller 6 when they work together to emboss.

[0036] Specifically, at least two horizontal switching cylinders 9 are fixedly installed on the frame 1. The output end of the switching cylinder 9 is fixedly installed to the bottom of the placement frame 8 by bolts. When the switching cylinder 9 is started, it drives the placement frame 8 and the embossing roller 6 at its upper end to move horizontally on the frame 1, thereby realizing the switching of the embossing roller 6.

[0037] It is understood that this utility model uses a linear guide rail and a switching cylinder to drive the placement frame to move horizontally in order to select different models of embossing rollers; then, the first cylinder and the lifting frame lift the selected embossing roller to the embossing station that cooperates with the drive roller, which improves the convenience and efficiency of operation, while reducing the labor intensity of switching.

[0038] One specific application of this embodiment is as follows: Figure 1 All the embossing rollers 6 shown are located on the placement frame 8. The lifting frame 3 is lower than the placement frame 8, and the lower bearing 31 is lower than the second bearing 62. At this time, the required embossing roller 6 can be moved directly below the drive roller 5 by the cooperation of the linear guide rail 7 and the switching cylinder 9. The lifting frame 3 is moved up by the first cylinder 2, and the lower bearing 31 on the lifting frame 3 contacts the second bearing 62 and lifts the corresponding embossing roller 6 upward until the second bearing 62 enters the upper bearing 42. The lower bearing 31 and the upper bearing 42 are pressed together, and the embossing roller 6 is lifted to the embossing position. During this process, the first bearing 61 moves up from the placement bearing 81 to the positioning seat 43. The motor 51 drives the drive roller 5 to rotate, and the embossing roller 6 rotates synchronously with the drive roller 5 through friction, thereby performing single-sided embossing work on the sound insulation cotton passing between the two.
