Description

Technical Field

[0001] This utility model relates to an impregnation and pressing mechanism. Background Technology

[0002] With the development of technology, impregnation and pressing mechanisms have been gradually applied to fabric processing. These mechanisms use two rollers to press the fabric together. Since the gap between the two rollers needs adjustment, the upper roller is typically driven to move up and down. A single motor via belt or chain cannot simultaneously drive both rollers; therefore, two motors are needed to drive each roller. The motor controlling the upper roller is fixed to a lifting base to ensure relative stability between the motor and the roller. However, this method increases costs, and controlling both motors to rotate at the same speed to maintain the roller's rotational speed is relatively complex. Utility Model Content

[0003] The purpose of this invention is to provide an impregnation and pressing mechanism to solve the technical problems mentioned in the background section.

[0004] The technical solution to achieve the purpose of this utility model is: an impregnation and pressing mechanism, including a frame, a first roller, a second roller, a drive assembly and a lifting assembly, wherein the first roller is rotatably mounted on the frame, the second roller is vertically mounted above the first roller, and the lifting assembly drives the second roller to move up and down; the drive assembly simultaneously drives the first roller and the second roller to rotate.

[0005] Furthermore, the lifting assembly includes a screw lifting module, a lifting seat, and a lifting guide rail. The lifting guide rail is fixed vertically on the frame. The lifting seat is located at the output end of the screw lifting module and is slidably connected to the lifting guide rail. The second roller is rotatably mounted on the lifting seat.

[0006] Furthermore, the lifting assembly also includes at least one pressure sensor, which is disposed between the lifting module and the lifting seat. The pressure sensor detects the pressure parameters of the second roller on the fabric. When only one pressure sensor is provided, one end of the pressure sensor is fixed to the output end of the screw lifting module, and the other end is fixed to the lifting seat.

[0007] Furthermore, when two pressure sensors are provided, the pressure sensors are located at both ends of the lifting base; a pressure plate is fixed to the output end of the lead screw lifting module, and the pressure plate is simultaneously fixed to both pressure sensors.

[0008] Furthermore, the drive assembly includes a drive device and a transmission assembly. The drive device drives the first roller to rotate and drives the second roller to rotate through the transmission assembly.

[0009] Furthermore, the transmission assembly includes a first connecting plate, a second connecting plate, and a first gear, a second gear, a third gear, and a fourth gear that are sequentially connected in transmission. The first gear is coaxially fixed with the first roller, and the fourth gear is coaxially fixed with the second roller. The central shafts of the first gear and the second gear are connected to the first connecting plate, and the central shafts of the third gear and the fourth gear are connected to the second connecting plate. The first connecting plate is sleeved on the central shaft of the third gear.

[0010] Furthermore, the lifting assembly is provided in two sets, respectively located at both ends of the second roller.

[0011] Furthermore, the frame includes wall panels at both ends, with U-shaped grooves formed on the wall panels. The lifting guide rail is fixed to the inner wall of the groove, and the lifting seat moves up and down within the U-shaped groove.

[0012] Furthermore, the bottom of the U-shaped groove is provided with a mechanical limiting device.

[0013] Furthermore, it also includes a displacement sensor, which is fixed to the outer surface of the wall panel.

[0014] Furthermore, the displacement sensor includes a first sensor and a second sensor; a contact block and a sensing plate are fixed on the lifting base, and the contact block and the sensing plate cooperate with the first sensor and the second sensor respectively.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) This utility model uses a lifting assembly to drive the second roller to lift and lower, thereby adjusting the gap between the first roller and the second roller to adapt to the processing of fabrics of different thicknesses. By using a drive assembly to drive the first roller and the second roller to rotate simultaneously, it reduces both the cost and the difficulty of control.

[0017] (2) The present invention forms a swing arm structure by means of a first connecting plate and a second connecting plate, so that the gear set will not disengage when the second roller is raised or lowered.

[0018] (3) This utility model sets the lifting guide rail in the U-shaped groove of the wall panel, which optimizes the layout of the equipment and saves space.

[0019] (4) The pressure sensor of this utility model can detect the pressure between two rollers. When two pressure sensors are set, the balance of the rollers can be judged at the same time, and then fed back to the lifting assembly for adjustment.

[0020] (5) The present invention sets the displacement sensor on the outer side of the wall panel by means of a bracket, which can reduce the impact of internal heat on the accuracy of the machine. Attached Figure Description

[0034] (Example 1)

[0035] See Figure 1-5 The impregnation and pressing mechanism of this embodiment includes a frame 1, a first roller 2, a second roller 3, a drive assembly, and a lifting assembly. The first roller 2 is rotatably mounted on the frame 1, and the second roller 3 is vertically mounted above the first roller 2. The lifting assembly drives the second roller 3 to rise and fall, and the drive assembly simultaneously drives the first roller 2 and the second roller 3 to rotate.

[0036] Specifically, the drive assembly includes a drive device 4 and a transmission assembly. The drive device 4 drives the first roller 2 to rotate and drives the second roller 3 to rotate through the transmission assembly.

[0037] See Figure 2The transmission assembly includes a first connecting plate 6, a second connecting plate 7, and a first gear 8, a second gear 9, a third gear 10, and a fourth gear 11 connected in sequence. The first gear 8 is coaxially fixed to the first roller 2, and the fourth gear 11 is coaxially fixed to the second roller 3. The central axes of the first gear 8 and the second gear 9 are connected to the first connecting plate 6, and the central axes of the third gear 10 and the fourth gear 11 are connected to the second connecting plate 7. The first connecting plate 6 is sleeved on the central axis of the third gear 10. When the lifting assembly drives the second roller 3 to rise and fall, the first connecting plate 6 and the second connecting plate 7 rotate around the first roller 2 and the second roller 3, respectively. At the same time, the first connecting plate 6 is sleeved on the central axis of the third gear 10. Therefore, the distance between adjacent gears does not change, and the first roller 2 can still drive the second roller 3 to rotate through the gear set when it rotates.

[0038] The lifting assembly includes a screw lifting module 12, a lifting seat 13, and a lifting guide rail 14. The lifting guide rail 14 is fixed vertically on the frame 1. The lifting seat 13 is located at the output end of the screw lifting module and is slidably connected to the lifting guide rail 14. The second roller 3 is rotatably mounted on the lifting seat 13. The screw lifting module 12 includes a drive motor and a screw. One end of the screw is located at the output end of the drive motor, and the output end of the screw is connected to the lifting seat 13. Controlling the lifting seat 13 to rise and fall through the screw lifting module 12 is a relatively mature technology in the industry and will not be elaborated further here. In this embodiment, two lifting assemblies are provided, respectively located at both ends of the second roller 3. The second roller 3 is raised and lowered by the lifting seat 13 driven by the screw lifting module 12. As a preferred embodiment, the screw in the screw lifting module 12 adopts a double-nut anti-backlash structure, which improves the control accuracy of the screw lifting module 12 and thus improves the lifting accuracy of the lifting seat 13.

[0039] See Figure 3 The frame 1 includes wall panels 1-1 at both ends. U-shaped grooves are provided on the wall panels 1-1. Lifting guide rails 14 are fixed on the inner sidewalls of the grooves. Lifting seat 13 moves up and down in the U-shaped grooves, which optimizes the layout of the equipment and saves space.

[0040] See Figure 4-5 The lifting assembly also includes at least one pressure sensor 15, which is disposed between the lifting module and the lifting base 13. The pressure sensor 15 detects the pressure parameters of the second roller 3 on the fabric. When only one pressure sensor 15 is provided, the pressure sensor 15 is directly opposite the axis of the second roller 3. One end of the pressure sensor 15 is fixed to the output end of the screw lifting module 12, and the other end is fixed to the lifting base 13.

[0041] When two pressure sensors 15 are provided, they are located at both ends of the lifting base 13. A pressure plate is fixed to the output end of the screw lifting module 12, and the pressure plate is also fixed to both pressure sensors 15. The pressure sensors 15 are also connected to the top of the lifting base 13 via a fixed bracket. With two pressure sensors 15, the balance of the rollers can be determined simultaneously, and then feedback is sent to the lifting assembly for adjustment.

[0042] It also includes displacement sensors, which are fixed to the outer surface of wall panel 1-1 by a bracket, which can reduce the impact of internal heat on accuracy. The displacement sensors include a first sensor 16 and a second sensor 17. A contact block 18 that cooperates with the first sensor 16 and a sensing plate 19 that cooperates with the second sensor 17 are fixed on the lifting seat 13. In this embodiment, the contact block 18 is L-shaped. The first sensor 16 is an elastic switch; when the second roller 3 descends, the contact block 18 contacts the first sensor 16, and the second roller 3 reaches its lower limit. In this embodiment, the second sensor 17 is a slotted photoelectric switch; when the second roller 3 rises, and the sensing plate 19 moves to the second sensor 17, the second roller 3 reaches its upper limit.

[0043] A mechanical limiting device 20 is provided at the bottom of the U-shaped groove (i.e., below the lifting seat 13). In this embodiment, the mechanical limiting device 20 is a limiting pad, which can prevent the upper and lower rollers from colliding.

[0044] The impregnation and pressing mechanism of this embodiment has a gap mode and a pressure mode. In gap mode, the lead screw lifting module 12 drives the second roller 3 to rise and fall to achieve the required gap. The thickness of the material to be processed is determined by the gap between the two rollers. Since the pressure sensor 15 is directly and rigidly connected to the output end of the lead screw lifting module 12, its deformation is small, which facilitates high-precision control. In pressure mode, after the pressure sensor 15 is zeroed, it can directly feed back the pressure applied to the material to be processed. The pressure of the second roller 3 on the material to be processed is adjusted according to the data fed back by the pressure sensor 15.

[0045] This invention adjusts the gap between the first roller 2 and the second roller 3 by raising and lowering the second roller 3 using a lifting assembly, thus accommodating fabrics of different thicknesses. By simultaneously rotating the first roller 2 and the second roller 3 using a drive assembly, both cost and control complexity are reduced. A screw-lifting module 12 is rigidly connected to a pressure sensor 15 to improve the control accuracy of the screw-lifting module 12 over the second roller 3. The gap control accuracy and repeatability are extremely high, reaching 1 micrometer, ensuring high product quality.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
