Description
Technical Field
[0001] This utility model belongs to the field of PVC calendered artificial leather production technology, specifically relating to an adjustable roller brush device for cleaning the cleaning surface of a foaming furnace needle plate and aluminum base. Background Technology
[0002] Foamed PVC calendered artificial leather undergoes foaming in a foaming oven (also called a foaming drying oven). Before entering the foaming process, the semi-finished artificial leather undergoes a calendering process to bond the PVC plastic to the base fabric. The portion of the base fabric wider than the PVC plastic surface is called the selvage. The left and right selvages are approximately the same width and symmetrically distributed. During the foaming process, if... Figure 1 and Figure 2 As shown, the two sides of the artificial leather semi-finished product 1 are hung longitudinally on the needle plates 2 on the left and right sides respectively. The needle plates 2 are fixed on the aluminum base 3, which is fixed on the chain 6 that can slide longitudinally along the longitudinal groove 5 of the horizontal track 4. Driven by the chain 6, the artificial leather semi-finished product 1 is driven by the aluminum base 3 and the needle plates to enter from the front inlet of the foaming oven and exit from the rear outlet. Because the artificial leather semi-finished product 1 contains the plasticizer DOP, at a temperature as high as 220-230℃, DOP vaporizes into gas and forms dense smoke. The dense smoke forms oil droplets or oil film when it cools down and accumulates on the needle plates. 2. If the metal surfaces of the aluminum base 3 and chain 6 are not effectively cleaned, they will carbonize. The carbon deposits (commonly known as coke) accumulate and become thicker, making them increasingly difficult to clean and forming stubborn dirt. The hazards are as follows: 1) The coke will break and splatter a lot of black impurities, which will form black spots on the PVC plastic surface, especially on light-colored PVC plastic surfaces, seriously affecting product quality; 2) The thick accumulation of coke on the surface of the needle plate 2 reduces the length of the protruding hanging needles 7 on the needle plate, and the fabric edge only hangs on a small part of the needle tip, making it easy to detach from the needle tip and unable to be properly stretched and shaped. Currently, cleaning the needle plate usually involves manually cleaning each needle plate one by one with a brush or electric roller after the machine is stopped. This is not only labor-intensive and inefficient, but the hanging needles on the needle plate can also easily injure the cleaner. At the same time, the cleaning operation affects the continuous production and the cleaning effect is not good. Utility Model Content
[0003] Based on the technical problem that the surfaces of the needle plate and aluminum base should be kept clean and free of charred material and debris, this utility model provides a safe and reliable adjustable roller brush device for cleaning the upper surface of the needle plate and the oblique side of the aluminum base online with excellent cleaning effect.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: an adjustable roller brush device for cleaning the needle plate and aluminum seat of a foaming furnace, including an outer frame, an inner frame, a horizontal guide rail, a lifting driver, an angle adjustment seat, a cleaning motor, and a rotating disk. The lifting driver is fixedly installed on the top of the outer frame, and the inner frame is vertically slidably connected inside the outer frame. The lower end of the lifting driver passes downward through the top of the outer frame and connects to the top of the inner frame. Vertical slide rails are respectively provided on the front and rear sides of the inner frame on the outer frame, and lifting sliders are respectively provided on the front and rear sides of the inner frame and slidably connected to the vertical slide rails. The angle adjustment seat is installed on the inner frame, the cleaning motor is installed on the angle adjustment seat, and the rotating disk is installed on the main shaft of the cleaning motor. The outer circle of the rotating disk is provided with an annular steel wire brush for cleaning the needle plate, and the end face of the rotating disk is provided with a disc steel wire brush for cleaning the aluminum seat.
[0005] The tilt adjustment seat includes a motor base and two adjustment bolts. The bottom of the motor base is rotatably connected to the bottom of the inner frame via a hinge. The hinge axis of the hinge runs along the front-to-back direction. The two adjustment bolts are located on the left and right sides of the hinge, respectively. The upper end of the adjustment bolt is hinged to the bottom of the motor base, and the lower end of the adjustment bolt passes through the bottom of the inner frame and is threaded with an adjustment nut. The top surface of the adjustment nut is pressed against the bottom of the inner frame.
[0006] The upper part of the outer frame has horizontal sliders on both the front and rear sides, and the middle part of the outer frame has a translation nut on each of the left and right sides. The two translation nuts are corresponding to each other and their center lines coincide. The center lines of the two translation nuts are both along the left and right direction.
[0007] The lifting drive uses a vertically positioned adjustable stroke cylinder, with the lower end of the piston rod of the adjustable stroke cylinder hinged to the top of the inner frame.
[0008] Using the above technical solution, a left column located to the left of the left chain and a right column located to the right of the right chain are vertically arranged on the ground behind the oven of the foaming furnace. The upper ends of the left and right columns are connected by a horizontal beam arranged horizontally in the left-right direction. Two horizontal beams are arranged side by side in front and behind, and a horizontal guide rail is fixed on each horizontal beam.
[0009] This utility model is provided in two sets during operation, with the two sets respectively located on the left and right sides of the crossbeam. The horizontal sliders on the front and rear sides of the upper part of the outer frame of this utility model are slidably connected to two transverse guide rails.
[0010] A transverse drive shaft passing through the two translation nuts of this utility model is provided between the two crossbeams. A handwheel is provided at the outer end of the transverse drive shaft. The transverse drive shaft is rotatably connected between the two crossbeams through a bearing seat adjacent to the handwheel. A rotary motion to linear motion component is provided between the transverse drive shaft and the two translation nuts.
[0011] The rotary motion to linear motion assembly includes a first hanger, a second hanger, an external threaded sleeve, and two pressure bearings. The first and second hangers are spaced apart on the left and right between two crossbeams. The transverse drive shaft is rotatably connected to the first and second hangers via bearings. The external threaded sleeve is fitted onto the transverse drive shaft and located between the first and second hangers. The inner circle of the external threaded sleeve is connected to the outer circle of the transverse drive shaft via a key. Two translation nuts are simultaneously threadedly connected to the outer circle of the external threaded sleeve. Both pressure bearings are installed on the outer circle of the transverse drive shaft. One pressure bearing is located between the left end of the transverse drive shaft and the first hanger, and the other pressure bearing is located between the right end of the transverse drive shaft and the second hanger.
[0012] The working principle of this utility model and its technical effects are as follows: (1) When PVC calendered artificial leather is foamed in a foaming oven (also called a foaming oven), the fabric edges on the left and right sides of the base fabric are respectively hung on the needle plates on the left and right sides. The chains on the left and right sides of the foaming oven move back and forth in the longitudinal chute in the horizontal track. The chains drive the aluminum seat and the needle plates that are hung on the fabric edges to move from front to back. The artificial leather semi-finished product enters from the front entrance of the foaming oven. After being foamed in the foaming oven, the artificial leather semi-finished product comes out from the rear exit. The fabric edges on the left and right sides of the foamed product are separated from the needle plates, supported by the guide rollers and conveyed to the rear. The chain drives the aluminum seat and needle plates to turn from back to front at the sprocket at the rear end. The online electric cleaning mechanism cleans the dirt on the surface of the needle plates and aluminum seats. The top open dirt boxes are placed directly below the two sets of this utility model on the left and right sides. The cleaned dirt falls into the dirt boxes for collection.
[0013] (2) The distance between the two horizontal rails (the distance between the left and right side needle plates) will widen or narrow as the width of the artificial leather product changes. When adjusting the distance between the two horizontal rails, the mechanical power drives several rail spacing adjustment screws to rotate simultaneously. Since the threads at the left and right ends of the rail spacing adjustment screws turn in opposite directions, the rail nuts connected to the bottom of the horizontal rails move left and right synchronously on the rail spacing adjustment screws, thereby realizing the adjustment of the distance between the two horizontal rails.
[0014] The left and right positions of the roller brush device are controlled by a handwheel. The specific manual operation process is as follows: While adjusting the distance between the two horizontal rails, rotate the handwheel to drive the transverse drive shaft to rotate. The transverse drive shaft drives the external threaded sleeve to rotate via a flat key. The left and right ends of the external threaded sleeve are respectively connected to the first and second hangers by a pressure bearing. Therefore, the external threaded sleeve can only rotate with the transverse drive shaft and cannot move axially. The two translation nuts screwed to the external threaded sleeve move left and right axially, driving the outer frame, inner frame, tilt adjustment seat, cleaning motor, and roller brush to move left and right along the transverse guide rail at the top of the crossbeam until the bottom of the roller brush contacts the needle plate and aluminum seat. Stop rotating the handwheel when this happens. When maintenance of the roller brush device is required or cleaning of the needle plate and aluminum seat is not needed, rotate the handwheel to disengage the bottom of the annular wire brush from the needle plate and aluminum seat.
[0015] When online cleaning is required, activate the lifting drive. The piston rod of the lifting drive (adjustable stroke cylinder) extends, driving the inner frame downwards until the annular wire brush contacts the needle plate. Activate the lifting drive and simultaneously tighten the cylinder stroke locking nut at the top of the adjustable stroke cylinder to lock the piston rod length. Activate the cleaning motor, which rotates the roller brush. The annular wire brush on the outer circumference of the roller brush cleans the needle plate as it returns from back to front, while the disc wire brush cleans the outer surface of the aluminum base.
[0016] Since the outer vertical surface of the aluminum base is sloped, the tilt adjustment seat can be adjusted to ensure that this surface is also cleaned. Specifically, first loosen the adjusting nut at the lower end of the adjusting bolt furthest from the aluminum base, then tighten the adjusting nut at the lower end of the adjusting bolt adjacent to the aluminum base. Rotate the motor base by a certain angle using the hinge at the bottom until the center line of the roller brush is perpendicular to the outer vertical surface of the aluminum base. Then tighten both adjusting nuts. Combined with the left-right movement of the handwheel-driven rotating disc and the lifting adjustment of the lifting drive, the outer vertical surface of the aluminum base can be thoroughly cleaned.
[0017] In summary, this utility model solves the shortcomings of traditional cleaning devices, such as low cleaning efficiency, high labor intensity, poor effect, inability to achieve online cleaning leading to long-term accumulation of dirt on the needle plate, increasing the difficulty of cleaning, and production stoppage for cleaning reducing effective production time. The cleaning device provided by this utility model has a scientific principle, is easy to use, and has high cleaning efficiency. It can achieve online cleaning, and by adjusting the tilt angle of the mounting plate, it can clean the inclined surface of the aluminum base, with a larger cleaning area and better effect.

The transverse drive shaft 23 is located below the crossbeam 15 and parallel to the crossbeam 15. A handwheel 18 is provided at the outer end of the transverse drive shaft 23. The transverse drive shaft 23 is rotatably connected between the two crossbeams 15 through the bearing seat 17 adjacent to the handwheel 18. A rotary motion to linear motion assembly is provided between the transverse drive shaft 23 and the outer frame 20. The tilt adjustment seat 25 is mounted on the inner frame 21, the cleaning motor 26 is mounted on the tilt adjustment seat 25, the rotating disk 27 is mounted on the main shaft of the cleaning motor 26, the outer circle of the rotating disk 27 is provided with an annular steel wire brush 32 for cleaning the needle plate 2, and the end face of the rotating disk 27 is provided with a disc steel wire brush 33 for cleaning the aluminum seat 3.
[0021] The rotary-to-linear motion assembly includes a first hanger 34, a second hanger 35, an external threaded sleeve 36, two translation nuts 37, and two pressure bearings 38. The first hanger 34 and the second hanger 35 are spaced apart between the two crossbeams. The transverse drive shaft 23 is rotatably connected to the first hanger 34 and the second hanger 35 through bearings. The external threaded sleeve 36 is fitted onto the transverse drive shaft 23 and located between the first hanger 34 and the second hanger 35. The inner circle of the external threaded sleeve 36 is connected to the outer circle of the transverse drive shaft 23 by a key. The two translation nuts 37 are respectively located on the left and right sides of the outer frame 20. The two translation nuts 37 are simultaneously threadedly connected to the outer circle of the external threaded sleeve 36. The two pressure bearings 38 are both installed on the outer circle of the transverse drive shaft 23. One pressure bearing 38 is located between the left end of the transverse drive shaft 23 and the first hanger 34, and the other pressure bearing 38 is located between the right end of the transverse drive shaft 23 and the second hanger 35.
[0022] The tilt adjustment seat 25 includes a motor seat 39 and two adjusting bolts 40. The bottom of the motor seat 39 is rotatably connected to the bottom of the inner frame 21 via a hinge 41. The hinge axis of the hinge 41 is along the front-back direction. The two adjusting bolts 40 are located on the left and right sides of the hinge 41, respectively. The upper end of the adjusting bolt 40 is hinged to the bottom of the motor seat 39, and the lower end of the adjusting bolt 40 passes through the bottom of the inner frame 21 and is threaded with an adjusting nut 42. The top surface of the adjusting nut 42 is pressed against the bottom of the inner frame 21.
[0023] The lifting drive 24 uses a stroke adjustable cylinder, and the lower end of the piston rod of the stroke adjustable cylinder is hinged to the top of the inner frame 21.
[0024] The working principle and process of this utility model are as follows: (1) When PVC calendered artificial leather is foamed in a foaming oven (also called a foaming oven), the left and right sides of the base fabric are respectively attached to the left and right needle plates 2. The chains 6 on the left and right sides of the foaming oven 12 move back and forth in the longitudinal slide 5 in the horizontal track 4. The chains 6 drive the aluminum seat 3 and the needle plate 2 attached to the fabric to move from front to back. It enters from the front entrance of the foaming oven 12. After the artificial leather semi-finished product is foamed in the foaming oven 12, it comes out from the rear exit. The fabric edges on the left and right sides of the foamed product are separated from the needle plate 2, supported by the guide roller and conveyed to the rear. The chains 6 drive the aluminum seat 3 and the needle plate 2 to turn from back to front at the sprocket at the rear end. The online electric cleaning mechanism 10 cleans the dirt on the surface of the needle plate 2 and the aluminum seat 3. The top open dirt box is placed directly below the two sets of adjustable roller brush devices 16. The cleaned dirt falls into the dirt box for collection.
[0025] (2) The distance between the two horizontal rails 4 (the distance between the left and right side needle plates) will widen or narrow as the width of the artificial leather product changes. When adjusting the distance between the two horizontal rails 4, the mechanical power drives several rail spacing adjustment screws 19 to rotate simultaneously through the worm gear mechanism 64. Since the threads at the left and right ends of the rail spacing adjustment screws 19 turn in opposite directions, the rail nuts connected to the bottom of the horizontal rails 4 move left and right synchronously on the rail spacing adjustment screws 19, thereby realizing the adjustment of the distance between the two horizontal rails 4.
[0026] The online electric cleaning mechanism 10 has two adjustable roller brush devices 16, each controlled by a handwheel 18. The specific manual operation process is as follows: While adjusting the distance between the two horizontal rails, the handwheel 18 is rotated to drive the transverse drive shaft 23 to rotate. The transverse drive shaft 23 drives the external threaded sleeve 36 to rotate via a flat key. The left and right ends of the external threaded sleeve 36 are respectively connected to the first hanger 34 and the second hanger 35 via a pressure bearing 38. Therefore, the external threaded sleeve 36 can only rotate with the transverse drive shaft 23 and cannot move axially. The two translation nuts 37 screwed to the external threaded sleeve 36 move left and right along the axial direction, driving the outer frame 20, inner frame 21, tilt adjustment seat 25, cleaning motor 26 and rotating disk 27 to move left and right along the transverse guide rail 22 at the top of the crossbeam 15 until the bottom of the rotating disk 27 contacts the needle plate 2 and the aluminum seat 3, at which point the handwheel 18 is stopped. When the adjustable roller brush device 16 needs maintenance or when the needle plate 2 and aluminum seat 3 do not need cleaning, simply rotate the handwheel 18 to detach the bottom of the annular wire brush 32 from the needle plate 2 and aluminum seat 3.
[0027] (3) When online cleaning is required, start the lifting drive 24. The piston rod of the lifting drive 24 (adjustable stroke cylinder) extends and drives the inner frame 21 to move downward until the annular wire brush 32 contacts the needle plate 2. Then, turn off the lifting drive 24 and tighten the cylinder stroke locking nut at the upper end of the adjustable stroke cylinder to lock the piston rod length. Start the cleaning motor 26 to drive the rotating disk 27 to rotate. The annular wire brush 32 on the outer circle of the rotating disk 27 cleans the needle plate 2 as it returns from back to front. At the same time, the disc wire brush 33 cleans the outer side of the aluminum base 3.
[0028] Since the outer vertical surface of the aluminum base 3 is sloped, the tilt adjustment seat 25 can be adjusted to clean the outer vertical surface of the aluminum base 3 as well. Specifically, first loosen the adjusting nut 42 at the lower end of the adjusting bolt 40 furthest from the aluminum base 3, then tighten the adjusting nut 42 at the lower end of the adjusting bolt 40 adjacent to the aluminum base 3. Rotate the motor base 39 by a certain angle using the hinge 41 at the bottom until the center line of the rotating disk 27 is perpendicular to the outer vertical surface of the aluminum base 3, then tighten both adjusting nuts 42. Combined with the handwheel 18 driving the left and right movement of the rotating disk 27 and the lifting adjustment of the lifting drive 24, a comprehensive cleaning of the outer vertical surface of the aluminum base 3 can be achieved.

However, the above descriptions are merely preferred embodiments and are not limited to these embodiments. Those skilled in the art, inspired by this patent, can make many modifications and improvements without departing from the spirit and scope of the claims, all of which fall within the protection scope of this utility model.
