Description

Technical Field

[0001] This utility model belongs to the field of PVC calendered artificial leather production technology, specifically relating to a cleaning device for a foaming furnace conveying needle plate and aluminum seat that is easy to operate with a clutch. 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 artificial leather semi-finished product 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 equal in width and symmetrically distributed. During the foaming process, the two selvages of the artificial leather semi-finished product 1 are hung longitudinally on the left and right needle plates 2, respectively. The needle plates 2 are fixed to the aluminum base 3, which is fixed to the chain 6, which slides longitudinally along the longitudinal groove 5 of the horizontal track 4. Driven by the chain 6, the artificial leather semi-finished product 1 is propelled through the aluminum base 3 and needle plates from the front inlet of the foaming oven to the rear outlet. It contains DOP plasticizer. At temperatures as high as 220-230℃, DOP vaporizes into gas, forming dense smoke. When the smoke cools, it forms oil droplets or oil films, which accumulate on the metal surfaces of the needle plate 2, aluminum base 3, and chain 6. If not effectively cleaned, it will carbonize. The carbonized material (commonly known as coke) accumulates more and more, becoming thicker and thicker, and becoming more and thicker, making it more difficult to clean and forming stubborn dirt. Its hazards are as follows: 1) The coke will break and splash 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. The fabric edge is only partially hooked on the needle tip and is easy to detach from the needle tip, making it impossible to stretch and shape properly. Currently, cleaning needle plates typically involves manual brushing or using an electric roller brush to clean each needle plate individually after the machine has stopped. This is not only labor-intensive and inefficient, but the needles hanging on the needle plate can also easily injure the cleaner. Furthermore, the cleaning operation disrupts continuous production and the cleaning effect is not ideal. Utility Model Content

[0006] The synchronous chain drive assembly is located near the left column. The synchronous chain drive assembly includes a drive sprocket mounted on the track spacing adjustment screw and a driven sprocket mounted on the transverse drive shaft. The inner circle of the drive sprocket is rotatably connected to the outer circle of the track spacing adjustment screw through a ball bearing. The inner circle of the driven sprocket is connected to the transverse drive shaft through a flat key. The drive sprocket and the driven sprocket are connected by a synchronous chain drive. The manual clutch includes a clutch wheel coaxially mounted on the track spacing adjustment screw. The clutch wheel is located between the left column and the drive sprocket. The outer circle of the track spacing adjustment screw has a guide groove along the axial direction. The inner circle of the clutch wheel is fixed with a guide key that slides along the guide groove. Four clutch protrusions are fixed on the right end face of the clutch wheel. Four clutch grooves are fixed on the left end face of the drive sprocket. The four clutch protrusions and four clutch grooves are arranged in a circumferential array along the center line of the track spacing adjustment screw. The distance between the center line of the clutch protrusion and the center line of the track spacing adjustment screw is equal to the distance between the center line of the clutch groove and the center line of the track spacing adjustment screw. The diameter of the clutch protrusion is slightly smaller than the diameter of the clutch groove. The outer circle of the clutch wheel has an annular groove. The right side of the left column has a hand drive rod assembly that cooperates with the annular groove and drives the clutch wheel to move to the right to engage with the drive sprocket and to move to the left to disengage from the drive sprocket.

[0007] The hand-drive lever assembly includes a support rod, an upper semi-circular ring, a lower semi-circular ring, a drive rod, a positioning rod, and a positioning seat. The left end of the support rod is fixed to the left column. The drive rod is rotatably connected to the support rod via a first pin. The upper and lower semi-circular rings are fitted onto the outer circle of the clutch wheel. Both ends of the upper and lower semi-circular rings are bent to form horizontal plates, which are fixedly connected by connecting bolts. An upper drive ring extending into the upper half of the annular groove is fixedly provided on the inner circle of the upper semi-circular ring, and a lower drive ring extending into the lower half of the annular groove is fixedly provided on the inner circle of the lower semi-circular ring. Two corresponding outer ear plates are provided parallel to each other at the bottom of the lower semi-circular ring. An inner ear plate extending between the two outer ear plates is provided at the upper end of the drive rod. Circular holes are provided on both outer ear plates, and a vertical elongated hole is provided on the inner ear plate. A connecting rod is inserted between the two circular holes and the vertical elongated hole. There is a second pin. Both the first and second pins are arranged in the front-to-back direction. The lower end of the drive rod has a U-shaped hole that is open at the bottom and open at the front and back. The upper end of the positioning rod extends into the U-shaped hole.

The top and front of the two positioning slots are open. When the lower end of the positioning rod extends into the left positioning slot, the clutch wheel moves to the right, and the four clutch protrusions extend into the four clutch slots one by one. The clutch wheel and the drive sprocket are coaxially engaged and rotate synchronously. When the lower end of the positioning rod extends into the right positioning slot, the clutch wheel moves to the left, the four clutch protrusions disengage from the four clutch slots, and the clutch wheel separates from the drive sprocket.

[0008] The rotary-to-linear motion assembly includes a first hanger, a second hanger, an external threaded sleeve, two translation nuts, and two pressure bearings. The first and second hangers are spaced apart on the left and right sides 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. The two translation nuts are respectively located on the left and right sides of the outer frame and are 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.

[0009] 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.

[0010] The lifting drive 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.

[0011] By adopting the above technical solution, this utility model has the following technical effects: (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 attached to 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 attached to 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 needle plates and aluminum seats. A dirt box with an open top is placed directly below the two sets of electric roller brush devices. The cleaned dirt falls into the dirt box for collection.

[0012] (2) The two sets of electric roller brush devices of the online electric cleaning mechanism are connected by a synchronous drive shaft; 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 horizontal rails, the mechanical power drives several rail distance adjustment screws to rotate simultaneously. Since the threads at the left and right ends of the rail distance adjustment screws rotate in opposite directions, the rail nuts connected to the bottom of the horizontal rails move left and right synchronously on the rail distance adjustment screws, thereby realizing the adjustment of the distance between the two horizontal rails; one of the rail distance adjustment screws drives the transverse drive shaft to rotate through the synchronous chain drive assembly (at this time, the lower end of the positioning rod in the manual clutch extends into the positioning groove on the left side of the positioning seat, and the four clutch protrusions of the clutch wheel extend into the four clutch grooves of the drive sprocket one by one, and the clutch wheel and the drive sprocket are coaxially combined and rotate synchronously). The transverse drive shaft is connected by a flat The key drives the external threaded sleeve to rotate. The left and right ends of the external threaded sleeve are respectively connected to the first and second hangers through 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 in the axial direction, driving the outer frame, inner frame, tilt adjustment seat, cleaning motor and rotating disk to move left and right along the transverse guide rail at the top of the crossbeam. At the same time, the transverse drive shaft drives another set of electric roller brush devices to rotate synchronously through the transmission shaft. In this way, while adjusting the horizontal track spacing, the spacing of the two sets of electric roller brush devices is also adjusted synchronously, so that the rotating disk and the needle plate and aluminum seat on the same side remain relatively stable in the left and right direction.

[0013] (3) When online cleaning is required, start the lifting drive. The piston rod of the lifting drive (adjustable stroke cylinder) extends, driving the inner frame to move downward until the annular wire brush contacts the needle plate. Then, turn off the lifting drive and tighten the cylinder stroke locking nut at the top of the adjustable stroke cylinder to lock the piston rod length. Start the cleaning motor to drive the rotating disk to rotate. The annular wire brush on the outer circle of the rotating disk cleans the needle plate as it returns from back to front, while the circular wire brush cleans the outer surface of the aluminum base.

[0014] 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 rotating disk is perpendicular to the outer vertical surface of the aluminum base. Then tighten both adjusting nuts. Combined with the lifting adjustment of the lifting drive, this allows for a thorough cleaning of the outer vertical surface of the aluminum base.

[0015] (4) Since this utility model is equipped with a manual clutch and handwheel, when the distance between the two horizontal rails is not adjusted, and it is necessary to temporarily stop the electric roller brush device, or to adjust the electric roller brush device in the left and right directions so that the disc wire brush can more effectively clean the outer side of the aluminum seat, the manual clutch can be operated to separate the clutch wheel from the drive sprocket. The specific operation process is as follows: First, rotate the positioning rod forward. The positioning rod rotates upward with the third pin as the fulcrum. The lower end of the positioning rod disengages from the left positioning groove. Then, move the lower end of the drive rod to the right. The drive rod rotates with the first pin as the fulcrum. The upper end of the drive rod moves to the left. The inner ear plate at the upper end of the drive rod drives the two outer ear plates to move to the left. The two outer ear plates drive the clutch wheel to move to the left on the track spacing adjustment screw through the lower semi-circular ring, upper semi-circular ring, lower drive ring, and upper drive ring. The clutch protrusion on the clutch wheel disengages from the clutch groove on the drive sprocket. At this time, since there is a ball bearing between the inner circle of the drive sprocket and the track spacing adjustment screw, the rotation of the track spacing adjustment screw will not drive the drive sprocket, and similarly, the rotation of the drive sprocket will not drive the track spacing adjustment screw. Finally, the positioning rod is rotated downward and backward, and the lower end of the positioning rod extends into the positioning groove on the right side, so that the clutch wheel is positioned in the axial direction.

[0016] After the clutch wheel disengages from the drive sprocket, rotating the handwheel causes the lateral drive shaft to rotate, which in turn moves the rotating disc and the circular wire brush left and right. The circular wire brush can then perform more targeted and wider-coverage cleaning of the outer inclined surface of the aluminum base. Alternatively, the annular wire brush can be detached from the needle plate to turn off the cleaning motor and pause the cleaning operation.

[0017] When it is necessary to coaxially engage and synchronously rotate the clutch wheel with the drive sprocket, remove the lower end of the positioning rod from the right positioning groove, and turn the lower end of the drive rod to the left. The drive rod rotates around the first pin as the fulcrum, and the upper end of the drive rod moves to the right. The inner ear plate at the upper end of the drive rod drives the two outer ear plates to move to the right. The two outer ear plates drive the clutch wheel to move to the right on the track spacing adjustment screw through the lower semi-circular ring, the upper semi-circular ring, the lower drive ring, and the upper drive ring. The clutch protrusion on the clutch wheel extends into the clutch groove on the drive sprocket. Finally, rotate the positioning rod downward and backward, and the lower end of the positioning rod extends into the left positioning groove, so that the clutch wheel is positioned in the axial direction.

[0018] The guide key, in conjunction with the guide groove, allows for axial movement of the clutch wheel and enables torque transmission between the track spacing adjustment screw and the clutch wheel. The lower and upper semi-circular rings are connected by bolts, forming a clamping structure for easy installation and disassembly, ensuring that the lower and upper drive rings remain within the annular groove on the outer circumference of the clutch wheel. A vertically elongated hole is provided on the inner ear plate. During drive rod rotation, the inner ear plate at the upper end of the drive rod experiences some vertical movement; therefore, the vertically elongated hole allows the second pin to move vertically within the hole, ensuring operational reliability.

[0019] 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 prolonged accumulation of dirt on the needle plate, increasing cleaning difficulty, and reduced effective production time due to shutdown for cleaning. The cleaning device provided by this utility model is scientifically based, easy to use, and highly efficient, enabling online cleaning. By manually adjusting the electric roller brush device to move left and right to contact or separate from the needle plate and aluminum base, the disc wire brush on the end face of the rotating disk can more easily and cover a larger area to contact the outer inclined surface of the aluminum base, thus resulting in a larger cleaning range and better effect. Furthermore, by adjusting the tilt angle of the mounting plate, the inclined surface of the aluminum base can be cleaned, resulting in a larger cleaning area and better effect.

[0028] 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 fabric edges on the left and right sides of the base fabric are respectively attached to the needle plates 2 on the left and right sides. The chains 6 on the left and right sides of the foaming oven 12 move back and forth in the longitudinal slid 5 in the horizontal track 4. The chains 6 drive the aluminum seat 3 and the needle plate 2 attached to the fabric edge 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 needle plate 2 and the aluminum seat 3. The top open dirt box is placed directly below the two sets of electric roller brush devices 16. The cleaned dirt falls into the dirt box for collection.

[0029] (2) The two sets of electric roller brush devices 16 of the online electric cleaning mechanism 10 are connected by a drive shaft 17 in a synchronous transmission; the distance between the two horizontal rails 4 (the distance between the left and right side needle plates 2) will be widened or narrowed according to the width of the artificial leather product. When adjusting the spacing of the horizontal rails 4, mechanical power drives several rail spacing adjustment screws 19 to rotate simultaneously via the worm gear mechanism 64. Since the threads at the left and right ends of the rail spacing adjustment screws 19 rotate 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 adjusting the spacing between the two horizontal rails 4. One of the rail spacing adjustment screws 19 drives the transverse drive shaft 23 to rotate via the synchronous chain drive assembly (at this time, the lower end of the positioning rod 83 in the manual clutch 18 extends into the left positioning groove 95 on the positioning seat 84, and the four clutch protrusions 77 of the clutch wheel 74 extend into the four clutch grooves 78 of the drive sprocket 70, and the clutch wheel 74 and the drive sprocket 70 are coaxially engaged and rotate synchronously). The transverse drive shaft 23 is connected via a flat... The key drives the external threaded sleeve 36 to rotate. The left and right ends of the external threaded sleeve 36 are respectively connected to the first hanger 34 and the second hanger 35 through 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 in 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. At the same time, the transverse drive shaft 23 drives another set of electric roller brush devices 16 to rotate synchronously through the transmission shaft 17. In this way, while adjusting the spacing of the horizontal track 4, the spacing of the two sets of electric roller brush devices 16 is also adjusted synchronously, so that the rotating disk 27 and the needle plate 2 and aluminum seat 3 on the same side remain relatively stable in the left and right direction.

[0030] (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.

[0031] 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, the adjustment method is as follows: 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. The motor base 39 is then rotated 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. Finally, tighten both adjusting nuts 42. Combined with the lifting adjustment of the lifting drive 24, the outer vertical surface of the aluminum base 3 can be thoroughly cleaned.

[0032] (4) Since this utility model is equipped with a manual clutch 18 and a handwheel 96, when the distance between the two horizontal rails is not adjusted and the electric roller brush device needs to be temporarily stopped, or when the electric roller brush device needs to be adjusted left and right to make the disc wire brush clean the outer side of the aluminum seat more effectively, the manual clutch 18 can be operated to separate the clutch wheel 74 from the drive sprocket 70. The specific operation process is as follows: First, rotate the positioning rod 83 forward. The positioning rod 83 rotates upward with the third pin 94 as the fulcrum. The lower end of the positioning rod 83 disengages from the left positioning groove 95. Then, pull the lower end of the drive rod 82 to the right. The drive rod 82 rotates with the first pin 92 as the fulcrum. The upper end of the drive rod 82 moves to the left. 2. The inner ear plate 90 at the upper end drives the two outer ear plates 89 to move to the left. The two outer ear plates 89 drive the clutch wheel 74 to move to the left on the track spacing adjustment screw through the lower semicircular ring 81, the upper semicircular ring 80, the lower drive ring 88, and the upper drive ring 87. The clutch protrusion 77 on the clutch wheel 74 disengages from the clutch groove 78 on the drive sprocket 70. At this time, since there is a ball bearing 72 between the inner circle of the drive sprocket 70 and the track spacing adjustment screw, the rotation of the track spacing adjustment screw will not drive the drive sprocket 70. Similarly, the rotation of the drive sprocket 70 will not drive the track spacing adjustment screw. Finally, the positioning rod 83 is rotated downward and backward. The lower end of the positioning rod 83 extends into the right positioning groove 95, so that the clutch wheel 74 is positioned in the axial direction.

[0033] After the clutch wheel 74 disengages from the drive sprocket 70, rotating the handwheel 96 rotates the transverse drive shaft 23, which drives the rotating disc and the disc wire brush to move left and right. The disc wire brush can perform more targeted and wider-coverage cleaning of the outer inclined surface of the aluminum base. Alternatively, the annular wire brush can be detached from the needle plate to turn off the cleaning motor and pause the cleaning operation.

[0034] When it is necessary to coaxially engage and synchronously rotate the clutch wheel 74 with the drive sprocket 70, remove the lower end of the positioning rod 83 from the right positioning groove 95, and turn the lower end of the drive rod 82 to the left. The drive rod 82 rotates around the first pin 92 as the fulcrum, and the upper end of the drive rod 82 moves to the right. The inner ear plate 90 at the upper end of the drive rod 82 drives the two outer ear plates 89 to move to the right. The two outer ear plates 89 drive the clutch wheel 74 to move to the right on the track spacing adjustment screw through the lower semi-circular ring 81, the upper semi-circular ring 80, the lower drive ring 88, and the upper drive ring 87. The clutch protrusion 77 on the clutch wheel 74 extends into the clutch groove 78 on the drive sprocket 70. Finally, rotate the positioning rod 83 downward and backward, and the lower end of the positioning rod 83 extends into the left positioning groove 95, so that the clutch wheel 74 is positioned in the axial direction.

[0035] The guide key 76 engages with the guide groove 75 to allow the clutch wheel 74 to move axially, and also to transmit torque between the track spacing adjustment screw and the clutch wheel 74. The lower semi-circular ring 81 and the upper semi-circular ring 80 are connected by connecting bolts 86 to form a clamping structure, which facilitates installation and disassembly and ensures that the lower drive ring 88 and the upper drive ring 87 are kept within the annular groove on the outer circumference of the clutch wheel 74. A vertical elongated hole 91 is provided on the inner ear plate 90. When the drive rod 82 rotates, the inner ear plate 90 at the upper end of the drive rod 82 will rise and fall to a certain extent in the vertical direction. Therefore, the vertical elongated hole 91 is provided on the inner ear plate 90 to allow the second pin 93 to move up and down within the vertical elongated hole 91, ensuring the reliability of operation.

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. Therefore, the patent and its scope of protection should be determined by the appended claims.
