[0028] Embodiment 1

[0029] As Figures 1 to 3 shown, the soundproofing membrane laying equipment of the utility model is consistent with the main structure of the existing material laying machine, and also comprises a rack 1, a cutting table 2, a cutter group 3, a cloth pulling frame 4 and a guide roller 5, the cutting table 2 and the cloth pulling frame 4 are vertically arranged on the workbench plate of the rack 1. The cloth pulling frame 4 can realize reciprocating linear motion along the length direction of the rack 1, that is, the longitudinal direction, through the linear guide rail 102 on the side wall of the workbench plate and the corresponding longitudinal driving system. A plurality of pneumatic clamps 401 are arranged on the side of the cloth pulling frame 4 facing the cutting table 2, and the plurality of pneumatic clamps 401 are arranged at equal intervals along the length direction of the cross beam of the cloth pulling frame 4. Correspondingly, a gap is provided on the clamping plate of the cutting table 2 for the clamping of the pneumatic clamps 401. The cutter group 3 is installed on the rear wall of the cutting table 2 through a transverse moving system, and the cutter group 3 adopts a disc cutter driven by a motor. The cutter group 3 can cut the soundproofing membrane material belt 12 clamped on the clamping plate of the cutting table 2 in the transverse direction. A material laying frame 101 is arranged on the front end wall of the rack 1 to install a soundproofing membrane material belt 12 roll. The output soundproofing membrane material belt 12 is changed in direction by the guide roller 5 and then enters the cutting table 2.

[0030] The soundproofing membrane laying equipment of the utility model is innovated in the important part of the existing material laying machine, and further comprises a flattening mechanism. The flattening mechanism is arranged between the guide roller 5 and the feeding end of the cutting table 2, and can flatten the soundproofing membrane material belt 12 to be laid. Because the thickness of the soundproofing membrane material belt 12 is relatively low compared with sheet materials such as artificial leather, paper and cloth belt, it is easy to wrinkle. It is very necessary to flatten the soundproofing membrane material belt 12 before laying to avoid the problem of misalignment of the edges when laying multiple layers.

[0031] The flattening mechanism is arranged between the guide roller 5 and the feeding end of the cutting table 2 to assist in flattening the relatively thin soundproofing membrane material belt 12, thereby reducing the wrinkling during conveying and improving the problem of misalignment of the edges when laying multiple layers of soundproofing membrane material belt 12.

[0032] In a specific embodiment of the embodiment, as Figure 1 and Figure 2 shown, the flattening mechanism comprises a flattening roller 6 and a rear guide roller 7. The rear guide roller 7 is arranged in front of the feeding end of the cutting table 2 and is arranged at the same height as the guide roller 5. The rear guide roller 7 and the guide roller 5 are both supported at the end by a support plate. The flattening roller 6 is arranged in parallel between the guide roller 5 and the rear guide roller 7 and presses the soundproofing membrane material belt 12 conveyed downward.

[0033] Through the combination of the guide roller 5, the flattening roller 6 and the rear guide roller 7, the soundproofing membrane material belt 12 is S-shaped bent and conveyed, the tension is increased, and the soundproofing membrane material belt 12 can be unfolded to a certain extent.

[0034] Specifically, as shown in Figure 1 and Figure 2 , the flattening roller 6 is supported on the top of the rack 1 through the support plate 603 at both ends, the waist-shaped hole 602 is formed in the upper part of the support plate 603, and the waist-shaped hole 602 is arranged in the vertical direction. The bolt is threadedly connected with the shaft end of the core shaft 601 of the flattening roller 6 after penetrating through the waist-shaped hole 602. A large circular flat pad is arranged between the bolt and the outer wall of the support plate 603.

[0035] By forming the vertical waist-shaped hole 602 in the upper part of the support plate 603, the installation height position of the flattening roller 6 can be adjusted, that is, the wrap angle of the soundproofing membrane material belt 12 on the guide roller 5, the flattening roller 6 and the rear guide roller 7 can be adjusted, and the soundproofing membrane material belt 12 with different thicknesses can be optimized and conveyed. For example, the soundproofing membrane material belt 12 with slightly larger thickness can adjust the position of the flattening roller 6 to realize smaller wrap angle conveying.

[0036] In a specific embodiment of the present embodiment, as shown in Figure 3 , the roller surface of the flattening roller 6 is an arc-shaped roller, and the middle diameter of the arc-shaped roller is large and the diameters of both ends gradually decrease.

[0037] By setting the roller surface of the flattening roller 6 as an arc-shaped roller, while conveying the soundproofing membrane material belt 12, the protruding part in the middle is used to apply pressure to the soundproofing membrane material belt 12, the soundproofing membrane material belt 12 is unfolded outward at both ends, the wrinkles are also opened, and the soundproofing membrane material belt 12 is conveyed flatly.

[0038] The working process of the soundproofing membrane laying device in the embodiment is as follows: initial state, the cloth pulling frame 4 is located at one end close to the cutting table 2, the front end opening of the pneumatic clamp 401 is inserted into the gap of the clamp plate, the pneumatic clamp 401 is actuated to clamp the head of the soundproofing membrane strip 12. The cylinder at the top of the cutting table 2 is actuated to open the upper half of the clamp plate, and the longitudinal driving system drives the cloth pulling frame 4 to move backward. The cloth pulling frame 4 pulls the soundproofing membrane strip 12 backward to complete the laying of the soundproofing membrane strip 12, and in the pulling process, the soundproofing membrane strip 12 on the feeding frame 101 starts to be fed, and the soundproofing membrane strip 12 sequentially passes through the top surface of the guide roller 5, the lower edge of the flattening roller 6 and the top surface of the rear guide roller 7 and then enters the clamp gap of the clamp plate. In this process, the combination of the guide roller 5, the flattening roller 6 and the rear guide roller 7 S-bends the soundproofing membrane strip 12, thereby increasing the tension and unfolding the soundproofing membrane strip 12. At the same time, the arc-shaped roller surface of the flattening roller 6 is in contact with the top surface of the soundproofing membrane strip 12, and the protruding part therebetween applies a pressure to the soundproofing membrane strip 12 from the middle to the two ends, thereby unfolding the soundproofing membrane strip 12 from the middle to the two ends. After the cloth pulling frame 4 is moved to the position, the transverse moving system drives the knife group 3 to move transversely, and the high-speed rotating disc cutter cuts the soundproofing membrane strip 12 clamped by the clamp plate of the cutting table 2 transversely. At the same time, the pneumatic clamp 401 of the cloth pulling frame 4 releases the head of the soundproofing membrane strip 12, the cut soundproofing membrane strip 12 is stacked with the soundproofing membrane strip 12 below, the cloth pulling frame 4 is reset to the one end close to the cutting table 2, and is ready for the next laying and cutting.

[0039] In summary, the soundproofing membrane laying device has the advantages that the flattening mechanism is arranged between the guide roller 5 and the feeding end of the cutting table 2 to assist in flattening the relatively thin soundproofing membrane strip 12, thereby reducing the wrinkling in the conveying process and being beneficial to improving the misalignment of the edges of the soundproofing membrane strip 12 during the laying of the multi-layer soundproofing membrane strip 12. In addition, the combination of the guide roller 5, the flattening roller 6 and the rear guide roller 7 S-bends the soundproofing membrane strip 12, thereby increasing the tension and unfolding the soundproofing membrane strip 12 to a certain extent. The vertical waist-shaped hole 602 is arranged on the upper part of the supporting plate 603, so that the installation height position of the flattening roller 6 can be adjusted, that is, the wrap angle of the soundproofing membrane strip 12 on the guide roller 5, the flattening roller 6 and the rear guide roller 7 can be adjusted, and the soundproofing membrane strip 12 with different thicknesses can be conveyed optimally. For example, the position of the flattening roller 6 can be adjusted to a higher position to realize the conveying of the soundproofing membrane strip 12 with a smaller wrap angle. The roller surface of the flattening roller 6 is arranged as an arc-shaped roller, so that the protruding part applies pressure to the soundproofing membrane strip 12 while conveying the soundproofing membrane strip 12, thereby unfolding the soundproofing membrane strip 12 from the middle to the two ends and conveying the soundproofing membrane strip 12 flatly.

[0040] Embodiment 2

[0041] The difference between the above embodiment 1 and this embodiment is that the flattening mechanism is replaced, and similar auxiliary flattening effect can be achieved. As shown in Figure 4 The flattening mechanism in this embodiment includes an arc-shaped rod 8 and a rear guide roller 7, which is arranged in front of the feeding end of the cutting table 2 and is arranged at the same height as the guide roller 5. The rear guide roller 7 needs to be additionally arranged in the same way as in the above embodiment 1. The arc-shaped rod 8 is arranged between the guide roller 5 and the rear guide roller 7, and the length direction of the arc-shaped rod 8 is arranged along the width direction of the sound-absorbing membrane strip 12. The front convex part of the arc-shaped rod 8 is pressed downward to the sound-absorbing membrane strip 12 conveyed rearward.

[0042] By additionally arranging the arc-shaped rod 8 between the guide roller 5 and the rear guide roller 7, the front convex part of the arc-shaped rod 8 is pressed downward to the middle position of the sound-absorbing membrane strip 12. During the conveying of the sound-absorbing membrane strip 12, the sound-absorbing membrane strip 12 is subjected to gradually decreasing pressing force from the middle to both ends, which can effectively eliminate the wrinkles of the sound-absorbing membrane strip 12.

[0043] Specifically, as shown in Figure 4 The root of the arc-shaped rod 8 is provided with a coaxial shaft head 801, and the outer wall of the shaft head 801 is provided with a whole circle of teeth, which is arranged in the axial direction of the shaft head 801. The shaft head 801 is connected to the rack 1 through the support seat 9. The top wall of the support seat 9 is provided with a threaded hole and is installed with a top screw 10. The inner end of the top screw 10 can abut to the outer wall of the shaft head 801.

[0044] Specifically, as shown in Figure 4 The top screw 10 is threadedly connected with a locking nut 11, and the locking nut 11 tightly presses the top screw 10 against the top wall of the support seat 9.

[0045] By arranging the shaft head 801 at the root of both ends of the arc-shaped rod 8, the shaft head 801 is inserted into the hole sleeve of the support seat 9, which can realize the rotation of the arc-shaped rod 8 around the center line of the shaft head 801, and further realize the adjustment of the downward pressing amount of the convex part of the arc-shaped rod 8. By installing the top screw 10 on the top wall of the support seat 9, the top screw 10 presses the teeth on the outer wall of the shaft head 801 to lock the shaft head 801, and further realizes the locking of the arc-shaped rod 8. By additionally arranging the locking nut 11 on the top screw 10, the top screw 10 can be prevented from loosening.

[0046] The working process of the soundproofing membrane laying device in the embodiment is as follows: different from the embodiment 1, the arc-shaped rod 8 in the embodiment is in sliding friction with the backwardly conveyed soundproofing membrane material belt 12, the blocking force is increased, and the unwrinkling effect is better. When the pressing force of the arc-shaped rod 8 needs to be adjusted, the two jackscrews 10 are loosened at the same time, the swinging angle of the arc-shaped rod 8 is manually adjusted, and the adjustment is made according to the thickness of the soundproofing membrane material belt 12 and the wrinkle amount. After the adjustment is completed, the jackscrews 10 are tightened again, and the locking nuts 11 are locked to the top wall of the support seat 9 to prevent the jackscrews 10 from loosening. The soundproofing membrane laying operation is normally performed after the machine is started.

[0047] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between the embodiments can be referred to each other. For the device disclosed in the embodiments, since it corresponds to the method disclosed in the embodiments, the description is relatively simple, and the related parts can be referred to the method part.

[0048] The above-described embodiments are only used to describe the preferred modes of the present application, and do not limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements of the technical solutions of the present application made by those skilled in the art shall fall within the protection scope determined by the claims of the present application.
