Description

Technical Field

[0001] This utility model relates to the field of rolling and leveling equipment technology, specifically to a rolling and leveling coating device for needle-punched felt. Background Technology

[0002] Gradient layered needle-punched felt is a material widely used in filtration and sound insulation. However, existing coating equipment often cannot adapt well to the gradient settings of gradient layered needle-punched felt, resulting in unstable product quality and easy damage to the gradient layer of the needle-punched felt during the rolling process.

[0003] According to the publication number (CN221000205U), a rolling coating device for gradient layered needle-punched felt is disclosed. The device is characterized by: a housing with a rolling cavity inside; a third groove on each of the two sides of the housing, the third groove being wavy; a first groove and a second groove on each of the two end faces of the housing; a winding roller rotatably connected to the first groove, the winding roller being fixedly connected to a drive source; two guide rollers rotatably connected to the second groove; a rolling assembly slidably connected to the third groove; and a limit block fixedly disposed on the outer wall of the housing, the limit block being provided with a drive assembly.

[0004] The implementation of this technical solution has at least the following drawbacks: Although this utility model can perform a flattening operation on needle-punched felt, it is inconvenient to separate the flattening roller from the flattened needle-punched felt after the flattening roller moves to the right end. This causes the gradient layer of the needle-punched felt to be affected during the resetting process of the flattening roller, which urgently needs improvement. Therefore, we propose a flattening coating device for needle-punched felt. Utility Model Content

[0005] The purpose of this invention is to provide a flattening coating device for needle-punched felt, which solves the problem mentioned in the background art that it is inconvenient to separate the flattening roller from the flattened needle-punched felt after the flattening roller moves to the right end, which causes the gradient layer of the needle-punched felt to be affected during the resetting process of the flattening roller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flattening coating device for needle-punched felt, comprising a fixed frame, a winding drum provided on one side of the fixed frame, a servo motor fixedly mounted on the upper end of the fixed frame, a lead screw mounted on the output end of the servo motor, an adjusting plate provided on the upper end of the inner cavity of the fixed frame, fixing strips provided on both the front and rear sides of the adjusting plate, a slider fixedly mounted on the upper end of the fixing strips, and a groove provided on the lower end of the adjusting plate;

[0007] A fixing block is fixedly installed on the upper end of the adjusting plate. The fixing block is movably connected to the fixing frame. Hydraulic cylinders are fixedly installed on both the left and right sides of the upper end of the fixing frame. Pressure sensors are fixedly installed on both sides of the upper end of the fixing frame, and the pressure sensors and the fixing block are set on the same horizontal plane.

[0008] By adopting the above technical solution, the lead screw and lead screw sleeve can drive the fixed block to move to the right. The fixed block drives the fixed strip on the adjusting plate to move accordingly, thereby enabling the flattening roller on the fixed strip to flatten the needle-punched felt. After the fixed block contacts the pressure sensor, the pressure sensor transmits the signal to the PLC controller. The PLC controller's servo motor reverses and simultaneously controls the hydraulic cylinder to extend. The hydraulic cylinder drives the lower pressure rod to move outward, separating the lower pressure rod from the fixed strip. Then, relying on the spring's elasticity, the spring drives the flattening roller on the fixed strip to separate from the needle-punched felt. This ensures that the flattening roller does not affect the gradient layer of the needle-punched felt during the reset process, thus facilitating the subsequent flattening operation of the needle-punched felt.

[0009] Optionally, a lead screw sleeve is fixedly installed in the middle of the fixing block, and the lead screw is threadedly connected to the lead screw sleeve.

[0010] By adopting the above technical solution, the adjustment plate can be moved by the cooperation of the lead screw and the lead screw sleeve.

[0011] Optionally, a flattening roller is rolled on the inner side of the fixing strip, and the flattening rollers are arranged symmetrically.

[0012] By adopting the above technical solution and setting up the flattening roller, the needle-punched felt can be flattened.

[0013] Optionally, the size of the slider is adapted to the size of the groove, and the slider and the groove are slidably connected.

[0014] By adopting the above technical solution, the stability of the fixing strip can be guaranteed through the cooperation of the slider and the groove.

[0015] Optionally, the inner cavity of the slide is provided with a spring, and the two ends of the spring are respectively fixedly connected to the slider.

[0016] By adopting the above technical solution and using the spring, the fixing bar can be reset, thereby achieving the separation effect of the flattening roller and the needle-punched felt.

[0017] Optionally, a downward pressure rod is installed at the output end of the hydraulic cylinder, and the downward pressure rod is located on the outside of the fixing bar.

[0018] By adopting the above technical solution and setting the pressure rod, the fixing strip can be pressed and adhered.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] The technical solution of this application, through the setting of a fixed frame, servo motor, adjusting plate, flattening roller, fixed block, pressing rod, and pressure sensor, can both enable the lead screw and lead screw sleeve to drive the fixed block to move to the right, and the fixed block to drive the fixed strip on the adjusting plate to move accordingly, thereby causing the flattening roller on the fixed strip to flatten the needle-punched felt. Furthermore, after the fixed block contacts the pressure sensor, the pressure sensor transmits a signal to the PLC controller, the PLC controller reverses the servo motor, and simultaneously controls the hydraulic cylinder to extend. The hydraulic cylinder drives the pressing rod to move outward, separating the pressing rod from the fixed strip. Then, relying on the spring's elasticity, the spring drives the flattening roller on the fixed strip to separate from the needle-punched felt. This ensures that the flattening roller does not affect the gradient layer of the needle-punched felt during the reset process, thus facilitating subsequent flattening operations on the needle-punched felt.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a flattening coating device for needle-punched felt, including a fixed frame 1, a winding drum 11 is provided on one side of the fixed frame 1, a servo motor 12 is fixedly installed on the upper end of the fixed frame 1, a lead screw 13 is installed on the output end of the servo motor 12, an adjusting plate 2 is provided on the upper end of the inner cavity of the fixed frame 1, a fixing strip 21 is provided on both the front and rear sides of the adjusting plate 2, a slider 23 is fixedly installed on the upper end of the fixing strip 21, and a groove 24 is opened on the lower end of the adjusting plate 2;

[0027] A fixing block 26 is fixedly installed on the upper end of the adjusting plate 2. The fixing block 26 is movably connected to the fixing frame 1. Hydraulic cylinders 4 are fixedly installed on both the left and right sides of the upper end of the fixing frame 1. Pressure sensors 5 are fixedly installed on both sides of the upper end of the fixing frame 1. The pressure sensors 5 and the fixing block 26 are set on the same horizontal plane. The size of the slider 23 is adapted to the size of the slide groove 24. The slider 23 and the slide groove 24 are slidably connected. The stability of the fixing strip 21 can be guaranteed by the cooperation between the slider 23 and the slide groove 24. A spring 25 is set in the inner cavity of the slide groove 24. The two ends of the spring 25 are fixedly connected to the slider 23 respectively. The setting of the spring 25 can drive the fixing strip 21 to reset, thereby achieving the separation effect of the flattening roller 22 and the needle-punched felt. A pressing rod 3 is installed on the output end of the hydraulic cylinder 4. The pressing rod 3 is set on the outside of the fixing strip 21. The pressing rod 3 can press and adhere the fixing strip 21.

[0028] A lead screw sleeve 27 is fixedly installed in the middle of the fixed block 26. The lead screw 13 is threadedly connected to the lead screw sleeve 27. The adjustment plate 2 can be moved by the cooperation between the lead screw 13 and the lead screw sleeve 27.

[0029] A flattening roller 22 is rolled on the inner side of the fixing strip 21, and the flattening rollers 22 are symmetrically arranged. The flattening rollers 22 can be used to flatten the needle-punched felt.

[0030] During flattening, the needle-punched felt is first passed between the two flattening rollers 22 and then wound around the outside of the take-up drum 11. Then, the servo motor 12 is turned on, and the servo motor 12 drives the lead screw 13 to rotate. The lead screw 13, in conjunction with the lead screw sleeve, drives the fixed block 26 to move to the right. The fixed block 26 drives the fixed strip 21 on the adjusting plate 2 to move accordingly, thereby causing the flattening roller 22 on the fixed strip 21 to flatten the needle-punched felt. When the fixed block 26 contacts the pressure sensor 5, the pressure sensor 5 transmits a signal to the PLC controller. The PLC controller reverses the servo motor 12 and simultaneously controls the hydraulic cylinder 4 to extend. The hydraulic cylinder 4 drives the lower pressure rod 3 to move outward, causing the lower pressure rod 3 to separate from the fixed strip 21. Then, due to the elasticity of the spring 25, the spring 25 drives the flattening roller 22 on the fixed strip 21 to separate from the needle-punched felt, thus ensuring that the flattening roller 22 does not affect the gradient layer of the needle-punched felt during the reset process, which facilitates the subsequent flattening operation of the needle-punched felt.
