[0033] Example:

[0034] See also Figure 1-Figure 7 The present invention provides a technical solution: a laminating device for automotive interior fabrics, comprising:

[0035] The conveying part 1 comprises a roller 11, and the roller 11 is connected to an external driving system, and a conveyor belt 12 is sleeved on the circumferential outer surface of the roller 11;

[0036] The laminating part 2 includes a pressing roller 21, which is located directly above the drum 11.

Two driving shafts 234 are designed and symmetrically distributed with the driven shaft 22 as the center. The central axis of the driving shaft 234 is lower than the central axis of the driven shaft 22.

[0040] The correction member 24 includes a frame 241, the bottom end of which is fixedly connected to the upper surface of the L-shaped base 231, and a lower threaded block 242 is rotatably installed on the upper surface of the frame 241 through a ring track, and the upper spiral surface of the lower threaded block 242 is tightly fitted with an upper spiral block 243, and a lifting rod 244 that slides with the inside of the frame 241 is fixedly connected to the lower surface of the upper spiral block 243, and the bottom end of the lifting rod 244 sequentially penetrates the lower threaded block 242 and the frame 241 and extends to the outside, and the lifting rod 244 is slidably connected to a sleeve rod 245 rotatably installed with the driven shaft 22 through a built-in groove 2441 opened at its bottom.

[0041] An adjustment plate 2442 that slides with the inner wall of the built-in groove 2441 is provided at the top of the sleeve rod 245, a strong spring 2443 is provided between the adjacent surfaces of the adjustment plate 2442 and the sleeve rod 245, and the lifting rod 244 is threadedly connected to the adjustment rod 2444 that is rotatably installed on the upper surface of the adjustment plate 2442 through a through hole opened inside.

[0043] A gear ring 2421 is sleeved on the circumferential outer surface of the lower threaded block 242, and a servo unit 2412 is fixedly connected to the side of the frame 241 close to the limit plate 2411, and the outer side of the servo unit 2412 is transmission-connected to a gear 2413 meshing with the gear ring 2421, and the bottom end of the gear 2413 is rotatably connected to the upper surface of the frame 241.

An inclined plate 2322 is fixedly connected inside the reinforcing seat 2321. A plurality of groups of electromagnetic blocks 2323 are fixedly connected to the upper surface of the inclined plate 2322. The inclined plate 2322 is parallel to the busbar of the driving shaft 234. A magnetic block 2451 which is magnetically connected to the electromagnetic block 2323 is provided at the bottom of the sleeve rod 245.

[0045] refer to Figure 1-Figure 7, using transmission belts, rollers and other components to transport the fabrics to be compounded to the pressing roller for compounding. The main function of the pressing roller is to compound the two fabrics together through heating and pressure to form a new composite material. In order to ensure the composite quality of the fabrics, the pressing roller is generally installed in a fixed manner, and thus the pressing roller cannot meet the lamination requirements of multi-layer fabrics;

[0046] In order to overcome the above-mentioned defects, the present invention designs a laminating and forming device for automobile interior fabrics.

[0047] Normal fabric lamination method:

[0048] In actual application, the fabrics are laid on the workbench in sequence according to the design requirements, and it is ensured that each layer of material is flat and has no obvious defects. Then, each layer of material is aligned and positioned by a positioning device. Subsequently, the roller 11 on the conveying part 1 is started, driving the conveyor belt 12 to reciprocate, driving the laid fabric to move toward the side of the pressure roller 21. When the fabric is close to the pressure roller 21, the drive box 232 on the driving member 23 is started, and its output end drives the driving shaft 234 to rotate. Since the conical surface of the driving shaft 234 is always tightly fitted with the conical surface of the driven shaft 22 (the end of the driven shaft 22 rotates around the sleeve rod 245 on the correction member 24, in the vertical direction, the sleeve rod 245, the lifting rod 244, the upper spiral block 243, and the damping rod 2431 are a whole. At the same time, the damping rod 2431 and the limit plate 2411 are internally damped and slide. Under the action of gravity, the conical surface of the driving shaft 234 is always tightly fitted on the conical surface of the driven shaft 22). There are two driving shafts 234 and they are symmetrically distributed on both sides of the driven shaft 22. Therefore, the two driving shafts 234 can simultaneously drive the driven shaft 22 to rotate clockwise by means of friction, and drive the pressure roller 21 to rotate clockwise. The pressure roller 21 cooperates with the roller 11 and the conveyor belt 12 to laminate the fabrics. The main function of the pressure roller 21 is to compound the two fabrics together through heating and pressure to form a new composite material.

[0049] Multi-layer fabric lamination method:

[0050] In actual applications, when facing the lamination of multiple layers of fabrics, the distance between the pressure roller 21 and the drum 11 needs to be fine-tuned to avoid damage to the multiple layers of fabrics due to overpressure. Start the servo unit 2412, and its output end drives the gear 2413 to rotate, which meshes and drives the gear ring 2421 to rotate, and drives the lower threaded block 242 to rotate around the annular track on the upper surface of the frame 241. Since the spiral surface of the lower threaded block 242 is always tightly fitted with the spiral surface of the upper spiral block 243, the lower threaded block 242 can drive the upper spiral block 243 to "short-distance displacement up and down" during its slow rotation, and the damping rod 2431 moves along the internal damping short distance of the limit plate 2411, driving the lifting rod 244, the sleeve rod 245, the driven shaft 22 and the pressure roller 21 to synchronously move up and down short distances, thereby meeting the short-distance fine-tuning requirements (there are two groups of correction parts 24 to achieve synchronous correction and adjustment of both ends of the pressure roller 21).

[0051] Then, the screw rod 233 on the driving member 23 is manually rotated to drive the driving box 232 to slide along the upper surface of the L-shaped base 231, and the driving shaft 234 is driven to move toward the side of the driven shaft 22 until the conical surface of the driving shaft 234 and the conical surface of the driven shaft 22 are tightly fitted again. There are two driving shafts 234, which are symmetrically distributed with the driven shaft 22 as the center, and the central axis of the driving shaft 234 is lower than the central axis of the driven shaft 22. The main functions of the driving shaft 234 are: first, the central axes of the two driving shafts 234 and the central axis of the driven shaft 22 are combined into a triangle, and the two driving shafts 234 are respectively located on both sides below the driven shaft 22, which greatly improves the transmission stability between the driven shaft 22 and the driving shaft 234; second, the two driving shafts 234 can drive the driven shaft 22 at the same time, and the overall transmission effect is better.

[0052] It is worth mentioning that when laminating multiple layers of fabrics, it is difficult to achieve one-time precise position adjustment during the up and down fine-tuning of the pressure roller 21. In order to prevent the multiple layers of fabrics from being directly crushed by the pressure roller 21, the lifting rod 244 and the sleeve rod 245 in the present application are debugged and coordinated to buffer the driven shaft 22 and the pressure roller 21. Initially, the top end of the sleeve rod 245 extends to the built-in groove 2441 and is engaged in the built-in groove 2441. The top end of the sleeve rod 245 is connected to the adjustment plate 2442 through the strong spring 2443. The position of the adjustment plate 2442 is fixed by the adjustment rod 2444 (the adjustment rod 2444 can correct the position of the adjustment plate 2442 in the built-in groove 2441 and adjust the elastic force of the strong spring 2443). Under the elastic force of the strong spring 2443 (always in a compressed state), the sleeve rod 245, the strong spring 2443, the adjustment plate 2442 and the lifting rod 244 will be combined into a whole to maintain the stability of the sleeve rod 245. When the multi-layer fabric passes through the pressure roller 21, if the pressure roller 21 is not adjusted enough, the multi-layer fabric will generate a reverse force on the pressure roller 21, driving the pressure roller 21 to move upward a short distance, driving the top of the sleeve rod 245 to move upward a short distance in the built-in groove 2441, and the strong spring 2443 is further compressed to produce elastic deformation. At the same time, the conical surface of the driven shaft 22 is separated from the conical surface of the driving shaft 234, and the pressure roller 21 no longer rotates autonomously, and thus the multi-layer fabric will not be heated and pressure-compounded.

[0053] After the position of the pressure roller 21 is precisely adjusted, in order to ensure that the pressure roller 21 can stabilize the pressure compounding and does not jump up and down, the present application is also provided with a reinforcing seat 2321, an inclined plate 2322, an electromagnetic block 2323 and a magnetic block 2451, and its advantages mainly include the following aspects:

[0054] Advantage 1: the reinforcing seat 2321 is sleeved on the outer circumferential surface of the output shaft of the driving box 232 , and the reinforcing seat 2321 and the driving box 232 are fixedly connected, which can ensure the smooth movement of the driving shaft 234 .

[0055] Advantage 2: After the electromagnetic block 2323 on the tilting plate 2322 is energized, the electromagnetic block 2323 acquires magnetism and is magnetically attracted to the magnetic block 2451, further enhancing the fit strength between the driven shaft 22 and the driving shaft 234, thereby preventing the two from separating during operation.

[0056] Advantage three, the inclined plate 2322 is parallel to the busbar of the active shaft 234, the electromagnetic block 2323 is much smaller than the magnetic block 2451, when the height of the driven shaft 22 is adjusted, since the conical surface of the active shaft 234 needs to be fitted to the conical surface of the driven shaft 22 again, during the movement of the active shaft 234, the inclined plate 2322 will also move synchronously with it, thereby ensuring that the distance between the magnetic block 2451 and the electromagnetic block 2323 below is always kept constant, providing stable magnetic force.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
