Description

Technical Field

[0001] This invention relates to the field of canvas impregnation technology, specifically to a wide-width winding device for industrial canvas production. Background Technology

[0002] Impregnated industrial canvas is a relatively thick synthetic fiber fabric, which is made into a cloth beam by a weaving machine and then produced by impregnation on an impregnation machine.

[0003] During the production process, the operator first inserts the square steel shaft into the hole of the wooden shaft during winding. Then, the wooden shaft is lifted onto the support roller, positioned, aligned, wrapped with fabric, and nailed with steel nails. Next, the clamping device centers and clamps the square steel shaft, while simultaneously applying pressure to the square steel shaft to press the wooden roller firmly onto the support roller. After this operation, winding begins. The existing operating method requires the square steel shaft to have sufficient rigidity and the operator to easily lift and lower it, which limits the length of the square steel shaft, resulting in the width of existing impregnation equipment generally being around 2400mm. This severely restricts the production efficiency of canvas impregnation equipment and the applicability of the products. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a wide-width winding device for industrial canvas production. This invention eliminates the use of a square steel shaft as the core shaft in the prior art, instead employing an upper pressure roller to press a wooden shaft, which is then clamped by a clamping head on a chuck device. This chuck device can move left and right, allowing for adjustable width and adapting to the production of wide and heavy-duty fabric shafts, thus solving the problems in the prior art.

[0005] The objective of this invention can be achieved through the following technical measures: The wide-width winding equipment for industrial canvas production of the present invention includes a frame consisting of a frame base and an upper frame mounted on the frame base (the lower frame and upper frame described in this invention can be installed and transported separately, avoiding transportation inconvenience due to the overall height of the equipment), support rollers A and B installed in parallel along the length of the frame base, a lower pressure roller device located directly below support roller A, a power unit of the main screw drive mechanism located below support roller B, an upper pressure roller device installed inside the upper frame, and two sets of amplitude adjustment devices arranged centrally symmetrically along the length of the upper pressure roller device; The upper frame is a rectangular frame structure consisting of four columns installed on both sides of the frame base, left and right longitudinal supports connected to the upper ends of the four columns, and front and rear upper crossbeams. The upper pressure roller device moves up and down through guide connecting plates at both ends and two sets of vertical slide rails symmetrically arranged on the left and right sides of the upper frame. The upper end of the main screw of the upper pressure roller mechanism is connected to the longitudinal support on the corresponding side. The lower end of the main screw is connected to the power output shaft of the main screw transmission mechanism through coupling V and reducer II. The amplitude adjustment device moves left and right through an internal slide block and a horizontal slide rail installed on the large crossbeam of the upper pressure roller device.

[0006] The frame base described in this invention includes left and right base plates, large wall plates vertically mounted on the corresponding side base plates, and crossbeams connecting the two large wall plates. One end of the support roller A is mounted on the corresponding side wall plate of the frame base, and the other end passes through the corresponding side wall plate and is directly connected to the winding motor A via coupling I. The support roller B is arranged side by side with the support roller A. The left and right shaft ends of the support roller B are respectively mounted on the flipping connecting plate on the corresponding side. A support seat is provided directly below the flipping connecting plate, and a weighing sensor is installed on the support seat. The weighing sensor supports the flipping connecting plate (providing support force when not flipping; detecting the weight of the cloth shaft when flipping, and controlling the pressure of the upper pressure roller on the surface of the cloth shaft based on the detection result). One end of the flipping connecting plate is mounted on the shoulder of the support roller A by hinge, and the other end is connected to the flipping cylinder. The tail seat of the cylinder is mounted on the base plate. Above; the flipping connecting plate serves as the flipping arm of the cloth shaft flipping device, with the shoulder of the support roller A as the rotating shaft. The flipping cylinder provides the flipping power and provides support force for the support roller B to flip the cloth shaft. An upper gear is installed at one end of the shaft of the support roller B, and a lower gear is installed at one end of the transition shaft. The upper gear and the lower gear are configured and meshed (which allows the support roller B to disengage when flipping and re-engage when falling). The transition shaft is installed on the corresponding side wall plate through a square seat bearing, and the other end is directly connected to the winding motor B through a coupling. The support roller A and support roller B are driven by independent motors (which can better control the winding tension and avoid the inconsistency of the linear speed of the two rollers due to the difference in roller surface wear, which would cause difficulty in tension control). Using the support roller A as the rotating shaft makes the structure more compact and greatly reduces the distance between the center of the wooden shaft and the front operating surface of the winding machine, making the operation more convenient and faster for the operator.

[0007] The lower pressure roller device of the present invention includes a lower pressure roller and sliding bearings respectively installed on the shaft ends of the lower pressure roller. The two sliding bearings are respectively installed on the slide rails of the bearing supports on the corresponding sides and connected to the lower pressure roller cylinders provided on the corresponding sides. The bearing supports are installed on the top surface of the lower pressure roller supports. The lower pressure roller cylinders are located inside the lower pressure roller supports. The bottom surface of the lower pressure roller supports is connected to the base plate (thus the present invention has the advantages of simple and compact structure, can be installed and disassembled as a whole, and is easy to maintain).

[0008] In this invention, the four columns of the upper frame are symmetrically arranged on the left and right sides of the frame base. The bottom surface of the columns is connected to the base plate, and the side surface of the columns is connected to the corresponding large wall panel. The upper ends of the two columns on the same side are connected to the longitudinal brace, forming a portal frame. The two portal frames are connected as one unit by an upper crossbeam. Two opposing vertical slide rails are installed vertically in the portal frame. One of the vertical slide rails has proximity switches at the upper, middle, and lower positions on one side (the proximity switches include a first proximity switch, a second proximity switch, and a third proximity switch; in this way, the invention controls the upper pressure roller to move up and down through a screw and slide rail transmission method, which has high precision, long stroke, heavy load, and can stop at any position. The first and third proximity switches can protect the upper pressure roller device from moving up and down. The second proximity switch allows the upper pressure roller device to move to the middle position first, and then the chuck device moves downward, which can greatly reduce the movement distance of the chuck device and make the mechanism for installing the chuck device more rigid and stable). The portal frame is equipped with the screw transmission part of the main screw transmission mechanism.

[0009] The upper pressure roller device of this invention includes an upper pressure roller, a large crossbeam, a guide connecting plate, a main screw nut, front and rear guide devices, and left and right guide devices. A guide connecting plate is installed at each of the left and right ends of the large crossbeam. The shaft ends of the upper pressure roller are respectively mounted on the corresponding guide connecting plates via bearings, and are located directly below the large crossbeam. Two opposing main nut supports are provided on the outer side of the guide connecting plate, with the main screw nut sandwiched in the middle. The main screw nut and the main screw together constitute a screw drive screw pair that drives the upper pressure roller device to move up and down. The front and rear guide devices are installed on both sides of the guide connecting plate in a triangular arrangement. Each group has two clamping plates distributed on both sides of the guide connecting plate. A guide bearing is provided between the two clamping plates, and the guide bearing is connected to the clamping plate via a pin. It forms a sliding relationship with two opposing vertical slide rails on the portal frame, maintaining the stability of the guide connecting plate in the front-to-back direction when it moves up and down. The left and right guide devices are installed on the guide connecting plate, opposite to the front and rear guide devices. Each group has two fixing blocks installed on both sides of the guide connecting plate. A connecting shaft is provided on the fixed block, and a clamping bearing is installed on the connecting shaft. The clamping bearings on both sides clamp a vertical slide rail on a U-shaped frame column, maintaining stability in the left-right direction when the guide connecting plate moves up and down. (This technical feature is that the upper pressure roller presses the fabric shaft, keeping the fabric surface flat and the pressure stable; the large crossbeam, guide connecting plate, and upper pressure roller form a whole, maintaining stable pressure, and the large crossbeam also provides an installation platform for the amplitude adjustment device.) During production, the upper pressure roller moves a distance equal to the diameter of the fabric shaft, while the clamping device only… The cloth shaft radius needs to be moved. The chuck device is connected to the main beam through an amplitude adjustment device and moves up and down with the upper pressure roller. This setting can effectively reduce the movement distance of the chuck device and improve the rigidity and stability of the chuck device structure. In order to meet the requirements of the cloth shaft roll diameter, the main screw is designed to be very long. During operation, there will inevitably be a small amount of sway. The main screw nut is not fixed, which can effectively prevent the main screw from getting stuck when it sways. Rolling bearings are used for the front and rear and left and right guides, which can reduce the machining accuracy and installation difficulty, and also effectively avoid jamming.

[0010] The amplitude adjustment device described in this invention includes two amplitude adjustment housings (left and right), an amplitude adjustment transmission device for driving the two amplitude adjustment housings to move relative to each other, a vertical moving device, and a chuck device installed at the lowest end of the vertical moving device (this configuration allows for adjustable winding width, greater adaptability, and the chuck device can move vertically to meet the clamping needs of fabric beams of various diameters); the amplitude adjustment transmission device is powered by an amplitude adjustment motor, which is installed in the middle of the upper surface of the main beam and directly connected to the left and right amplitude adjustment lead screws via coupling II. The two right-hand amplitude adjustment screws rotate in opposite directions to drive the left and right amplitude adjustment boxes to make relative displacement movements along the longitudinal direction of the main beam. The inner shaft of the amplitude adjustment screw is mounted on the main beam through a seat bearing, and the outer shaft of the amplitude adjustment screw is mounted in the screw support through a rolling bearing. A locking nut is provided to prevent the screw from moving. The screw support is connected to the main beam. (This technical solution can realize the amplitude adjustment device to move back and forth along the longitudinal direction of the main beam within the set range on the corresponding side, and drive the clamping device to achieve relative or opposite movements, so as to achieve the purpose of clamping and disengaging the cloth shaft.)

[0011] The amplitude modulation box described in this invention comprises a two-layer frame structure consisting of a lower base plate, side plates, a middle connecting plate, an upper top plate, and reinforcing supports. The lower base plate serves as the base, with two side plates installed on either side. The upper top plate connects the tops of the two side plates to form a frame structure. The middle connecting plate is horizontally installed in the middle of the inner sides of the two side plates, dividing the frame into upper and lower layers. The reinforcing supports connect the lower base plate and side plates to strengthen the frame. A large horizontal beam passes through the lower frame. The large horizontal beam has two horizontal slide rails installed symmetrically on its upper and lower sides, allowing the left and right amplitude modulation boxes to move on them. Each of the two horizontal slide rails on each side has two sliding blocks; the lower two sliding blocks are connected to the lower base plate, and the upper two sliding blocks are connected to the lower side plate. Two sliding blocks are connected to the central connecting plate. The entire amplitude adjustment box is slidably connected to the main beam through the sliding blocks and horizontal slide rails. Two proximity switches are also provided on one side plate, which together with the limit plates installed at both ends of the horizontal slide rail of the main beam form a limit detection structure. The amplitude adjustment screw passes through the upper frame and forms a helical pair with the amplitude adjustment nut sleeved on the amplitude adjustment screw, which pushes the entire amplitude adjustment box to move left and right on the main beam. The amplitude adjustment nut is held by two nut clamps, which are connected to the central connecting plate on the frame. (In this technical solution, the amplitude adjustment box adopts an assembly structure, which is simple to install and easy to disassemble. The standard slide rail and sliding block are matched, which has high precision, small gap, flexible movement and stable structure.)

[0012] The vertical moving device described in this invention consists of a U-shaped frame composed of a clamp mounting base and two long side plates, an upper connecting plate connecting the tops of the two long side plates to form a closed structure, and an overall moving structure formed by connecting and reinforcing the long side plates and the upper connecting plate with two reinforcing clamps. The two long side plates are distributed on both sides of the amplitude modulation box through the slots on both sides of the bottom plate of the box, and are guided and slidably connected by a set of relatively vertical slide rails installed on the inner side of the two long side plates and slide blocks II installed on the corresponding side of the side plates of the amplitude modulation box. Two limit bolts and a proximity switch are installed on the upper connecting plate. A cylinder connector connecting seat and a limit block are installed on the outer side of the lower end of each of the two long side plates. The lifting cylinder is connected to the bottom plate of the amplitude adjustment box. The lifting cylinder drives the up and down moving device to move up and down along the amplitude adjustment box. The clamping device is also installed on the clamping mounting seat at the lower end of the U-shaped frame (the closed U-shaped frame structure is more stable in this way, and the combined structure makes the installation simple and feasible. The limit bolt at the top protects the proximity switch and also limits the farthest position of the clamping device from the main beam. It is used to align the clamping device with the wooden shaft. The limit block at the bottom of the side plate can limit the closest position of the clamping device to the main beam, and protect the bottom of the up and down moving device from hitting the upper pressure roller when it rises to the highest point. The lifting cylinder is used to control the up and down moving device to follow the center of the cloth shaft after clamping the cloth shaft).

[0013] The clamping device described in this invention includes a snapping shaft. A clamp for holding the head of the fabric shaft is installed on the front end face of the snapping shaft. Bearings are installed at both ends of the head of the snapping shaft. The outer ring of the bearing is installed on the inner hole of the sliding sleeve. A connector is installed at one end of the sliding sleeve and is connected to the rod of the snapping cylinder. The snapping cylinder is installed on the outer side of the clamping seat. The snapping cylinder pushes the sliding sleeve to slide in the inner hole of the sleeve. The sleeve is connected to the inner side of the clamping seat. A part of its cylinder body extends into the inner hole of the clamping seat, and the other part is exposed on the outside. A photoelectric switch is provided on the outer cylinder body (this invention uses a photoelectric switch to detect whether the clamping device has moved into place, control the amplitude modulation motor to stop, and the snapping cylinder snaps. The snapping cylinder pushes the sliding sleeve to slide in the sleeve, thereby driving the snapping shaft to move and clamp the fabric shaft. After the snapping shaft clamps the fabric shaft, it can rotate with the fabric shaft).

[0014] The main lead screw transmission mechanism described in this invention includes a servo motor, reducer I, reducer II, a transmission shaft, and a main lead screw. The servo motor is mounted on a connecting plate and is directly connected to the input shaft of reducer I via coupling III. The output shafts on both sides of reducer I are connected to the transmission shaft via coupling IV. The transmission shaft is connected to the reducer mounted on the outside of the large wall plate via coupling IV. The output shaft of reducer II is directly connected to the main lead screw shaft head via coupling V. One end of the main lead screw is connected to the longitudinal brace of the upper frame via a bearing seat, and the other end is mounted on a lead screw support seat, which is fixed to the large wall plate. The main lead screw shaft head is connected to the lead screw support seat via a pair of rolling bearings and a pair of thrust bearings. A locking nut is provided at the end for locking (in this way, the servo motor outputs torque through the transmission shaft, the reducer decelerates and changes the transmission direction, and the main lead screw drives the load, resulting in high transmission accuracy, large output torque, simple structure, and convenient installation).

[0015] The beneficial effects of this invention are as follows: The device of this invention eliminates the traditional structure of manually threading square steel shafts to make cloth shaft mandrels, completely eliminating the limitations imposed by the rigidity and weight of square steel shafts on the width and diameter of cloth shafts, improving the automation level of the equipment and reducing labor intensity; it also achieves adjustable width, can adapt to the impregnation of cloth shafts of various widths, and has stronger adaptability and a wider range of applications.

[0024] The present invention will be further described below with reference to embodiments (see accompanying drawings): like Figure 1 , Figure 5 , Figure 6As shown, the wide-width winding equipment for industrial canvas production of the present invention includes a frame consisting of a frame base 2 and an upper frame 1 mounted on the frame base (the lower frame and upper frame described in the present invention can be installed and transported separately, without causing transportation inconvenience due to the overall height of the equipment), support rollers A4 and B6 installed in parallel along the length direction of the frame base 2, a lower pressure roller device 5 located directly below the support roller A4, a power section of the main screw drive mechanism 9 located below the support roller B6, an upper pressure roller device 8 installed inside the upper frame 1, and two sets of amplitude adjustment devices 10 arranged in a centrally symmetrical manner along the length direction of the upper pressure roller device 8; the upper frame 1 is composed of four... The rectangular frame structure consists of columns 14 installed on both sides of the frame base 2, left and right longitudinal supports 20 connected to the upper ends of the four columns 14, and front and rear upper crossbeams 21. The upper pressure roller device 8 moves up and down through guide connecting plates 43 at both ends and two sets of vertical slide rails 16 symmetrically arranged on the left and right sides of the upper frame 1. The upper end of the main screw 18 used to drive the upper pressure roller mechanism is connected to the corresponding longitudinal support 20. The lower end of the main screw 18 is connected to the power output shaft of the main screw transmission mechanism 9 through coupling V88 and reducer II89 respectively. The amplitude adjustment device 10 moves left and right through the internal slide 67 and the horizontal slide rail 53 installed on the upper pressure roller device's large crossbeam 42.

[0025] like Figure 1 , Figure 2As shown, the frame base 2 of this invention includes left and right base plates 13 and large wall plates 12 vertically mounted on the corresponding side base plates, and a crossbeam 11 connecting the two large wall plates; one end of the support roller A4 is mounted on the large wall plate 12 on the corresponding side of the frame base, and the other end passes through the large wall plate on the corresponding side and is directly connected to the winding motor A22 via coupling I24; the support roller B6 is arranged side by side with the support roller A4, and the left and right shaft ends of the support roller B6 are respectively mounted on the flipping connecting plate 29 on the corresponding side. A support seat 32 is provided directly below the flipping connecting plate, and a weighing sensor 30 is installed on the support seat. The weighing sensor supports the flipping connecting plate (providing support force when not flipping; and detecting the weight of the cloth shaft when flipping, and controlling the pressure of the upper pressure roller on the surface of the cloth shaft according to the detection result); one end of the flipping connecting plate 29 is mounted on the shoulder of the support roller A4 by hinge, and the other end is connected to the flipping cylinder 33. The cylinder tail seat 34 is mounted on the bottom. On plate 13; the flipping connecting plate 29 serves as the flipping arm of the cloth shaft flipping device 3, with the shoulder of the support roller A4 as the rotating shaft. The flipping cylinder 33 provides the flipping power and provides support force for the support roller B6 to flip the cloth shaft; one end of the support roller B6 shaft is equipped with an upper gear 28, and the lower gear 31 is installed at one end of the transition shaft 26. The upper gear 28 and the lower gear 31 are arranged vertically and meshed (which can facilitate disengagement when the support roller B6 flips and re-engagement when it falls). The transition shaft 26 is installed on the corresponding side wall plate through a square seat bearing 27, and the other end is directly connected to the winding motor B23 through a coupling 25; the support roller A4 and the support roller B6 are driven by independent motors (which can better control the winding tension and avoid the inconsistency of the linear speed of the two rollers due to the difference in roller surface wear, which makes tension control difficult). Using the support roller A4 as the rotating shaft makes the structure more compact and greatly reduces the distance between the center of the wooden shaft and the front operating surface of the winding machine, making the operation more convenient and faster for the operator.

[0026] like Figure 1 , Figure 3 As shown, the lower pressure roller device 5 of the present invention includes a lower pressure roller 35 and sliding bearings 37 respectively installed on the shaft heads at both ends of the lower pressure roller. The two sliding bearings 37 are respectively installed on the slide rails of the bearing supports 36 on the corresponding sides and connected to the lower pressure roller cylinders 38 provided on the corresponding sides. The bearing supports 36 are installed on the top surface of the lower pressure roller support 39. The lower pressure roller cylinders 38 are located inside the lower pressure roller support 39. The bottom surface of the lower pressure roller support 39 is connected to the base plate 13 (thus the present invention has the advantages of simple and compact structure, can be installed and disassembled as a whole, and is easy to maintain).

[0027] like Figure 1As shown, in this invention, the four columns 14 of the upper frame 1 are symmetrically arranged on the left and right sides of the frame base 2. The bottom surface of the columns 14 is connected to the base plate 13, and the side surface of the columns 14 is connected to the corresponding large wall panel 12. The upper ends of the two columns on the same side are connected to the longitudinal brace 20 to form a U-shaped frame. The two U-shaped frames on both sides are connected as one unit by the upper crossbeam 21. Two opposing vertical slide rails 16 are installed in the vertical direction of the U-shaped frame. A proximity switch (including a first proximity switch 15 and a second proximity switch) is provided at the upper, middle and lower positions on one side of one of the vertical slide rails. 17. Third proximity switch 19; Thus, the present invention controls the up and down movement of the upper pressure roller through a screw and slide rail transmission method, which has high precision, long stroke, heavy load, and can stop at any position. The first proximity switch 15 and the third proximity switch 19 can protect the up and down position of the upper pressure roller device 8. The second proximity switch 17 can make the upper pressure roller device 8 move to the middle position first, and then the chuck device 7 moves downward, which can greatly reduce the movement distance of the chuck device and make the rigidity and stability of the mechanism for installing the chuck device better. The main screw transmission mechanism 9 is provided inside the portal frame.

[0028] like Figure 1 , Figure 4As shown, the upper pressure roller device 8 of this invention includes an upper pressure roller 41, a large crossbeam 42, a guide connecting plate 43, a main screw nut 51, front and rear guide devices 99, and left and right guide devices 98; a guide connecting plate 43 is installed on the left and right ends of the large crossbeam 42; the shaft ends of the upper pressure roller 41 are respectively mounted on the guide connecting plates 43 on the corresponding sides through bearings, and are located directly below the large crossbeam 42; the outer side of the guide connecting plate 43 is provided with two opposing main nut supports 50, with the main screw nut 51 sandwiched in the middle, and the main screw nut 51 and the main screw 18 together constitute the drive upper pressure roller device. The screw drive screw pair moves up and down; the front and rear guide devices 99 are installed on both sides of the guide connecting plate 43 in a triangular distribution. Each group has two clamping plates 44, distributed on both sides of the guide connecting plate 43. A guide bearing 45 is provided between the two clamping plates 44. The guide bearing 45 is connected to the clamping plate 44 through a pin 46 and forms a sliding relationship with two vertical slide rails 16 on the portal frame to maintain the stability of the guide connecting plate 43 in the front and rear directions when it moves up and down; the left and right guide devices 98 are installed on the guide connecting plate 43 and are distributed opposite to the front and rear guide devices 99. Each group has two clamping plates 44, distributed on both sides of the guide connecting plate 43 in a triangular distribution. Two fixing blocks 49 are provided, installed on both sides of the guide connecting plate 43. A connecting shaft 48 is provided on each fixing block 49, and a clamping bearing 47 is installed on the connecting shaft 48. The clamping bearings 47 distributed on both sides clamp a vertical slide rail 16 on the U-shaped frame column, maintaining the stability of the guide connecting plate 43 in the left-right direction when it moves up and down. (This technical feature is that the upper pressure roller presses the fabric shaft, which can keep the fabric surface flat and the pressure stable; the large crossbeam, guide connecting plate, and upper pressure roller form a whole, which can maintain stable pressure, and the large crossbeam also provides an installation platform for the amplitude adjustment device.) During production operation... The upper pressure roller moves a distance equal to the diameter of the fabric shaft, while the clamping device only needs to move a radius distance of the fabric shaft. The clamping device is connected to the large crossbeam via an amplitude adjustment device and moves up and down with the upper pressure roller. This configuration effectively reduces the moving distance of the clamping device and improves the rigidity and stability of the clamping device structure. To meet the requirements for the fabric shaft roll diameter, the main screw is designed to be very long, and slight swaying is inevitable during operation. The main screw nut is not fixed, which effectively prevents the main screw from getting stuck when it sways. Rolling bearings are used for the front-to-back and left-to-right guides, which reduces the machining accuracy and installation difficulty, and also effectively avoids jamming.

[0029] like Figure 1 , Figure 5As shown, the amplitude adjustment device 10 of this invention includes two amplitude adjustment boxes 100 (left and right), an amplitude adjustment transmission device 101 for driving the two amplitude adjustment boxes to move relative to each other, a vertical moving device 102, and a clamping device 7 installed at the lowest end of the vertical moving device (this arrangement allows for adjustable winding width, greater adaptability, and the clamping device can move vertically to meet the clamping needs of fabric beams of various diameters); the amplitude adjustment transmission device 101 is powered by an amplitude adjustment motor 64, which is installed in the middle of the upper surface of the main beam 42 and directly connected to the two amplitude adjustment lead screws 54 on the left and right sides via a coupling II 65. The left and right amplitude adjustment screws 54 rotate in opposite directions to drive the left and right amplitude adjustment boxes 100 to make relative displacement movements along the longitudinal direction of the main beam 42. The inner shaft of the amplitude adjustment screw 54 is mounted on the main beam 42 through a seat bearing 66, and the outer shaft of the amplitude adjustment screw 54 is mounted in the screw support 52 through a rolling bearing. A locking nut is provided to prevent the screw from moving. The screw support 52 is connected to the main beam 42. (This technical solution can realize the amplitude adjustment device 10 to move back and forth along the longitudinal direction of the main beam 42 within the set range on the corresponding side, and drive the clamping device to realize relative or opposite movements, so as to achieve the purpose of clamping and disengaging the cloth shaft.)

[0030] like Figure 5 As shown, the amplitude adjustment box 100 of this invention consists of a lower base plate 79, side plates 78, a middle connecting plate 63, an upper top plate 60, and a reinforcing support 80, forming a two-layer frame structure. The lower base plate 79 serves as the base, with two side plates 78 installed on both sides. The upper top plate 60 connects the tops of the two side plates 78 to form a frame structure. The middle connecting plate 63 is horizontally installed in the middle of the inner side of the two side plates 78, dividing the frame into upper and lower layers. The reinforcing support 80 connects the lower base plate 79 and the side plates 78 to reinforce the frame. A large horizontal beam 42 passes through the lower frame. The large horizontal beam 42 has two horizontal slide rails 53 installed on its upper and lower sides in a centrally symmetrical manner, allowing the left and right amplitude adjustment boxes 100 to move on them. Each of the two horizontal slide rails 53 on each side has two sliding blocks 67. The two lower sliding blocks 67 are connected to... The lower base plate 79 is connected, and the two upper slides 67 are connected to the middle connecting plate 63. The entire amplitude adjustment box 100 is slidably connected to the main beam 42 through the slides 67 and the horizontal slide rail 53. One of the side plates 78 is also equipped with two proximity switches 69, which together with the limit plates 68 installed at both ends of the horizontal slide rail of the main beam form a limit detection structure. The amplitude adjustment screw 54 passes through the upper frame and forms a helical pair with the amplitude adjustment nut 61 fitted on it, which pushes the entire amplitude adjustment box 100 to move left and right on the main beam 42. The amplitude adjustment nut 61 is clamped by two nut clamps 62, which are connected to the middle connecting plate 63 on the frame. (In this technical solution, the amplitude adjustment box adopts an assembly structure, which is simple to install and easy to disassemble. The standard slide rail and slides are matched, which has high precision, small gap, flexible movement and stable structure.)

[0031] like Figure 5As shown, the vertical moving device 102 of this invention consists of a U-shaped frame composed of a clamp mounting base 72 and two long side plates 75, an upper connecting plate 58 connecting the top ends of the two long side plates 75 to form a closed structure, and an overall moving structure formed by connecting and reinforcing the long side plates 75 and the upper connecting plate 58 through two reinforcing clamps 59. The two long side plates 75 are distributed on both sides of the box body through the slots on both sides of the bottom plate 79 of the amplitude adjustment box body, and are guided and slidably connected by a set of relatively vertical slide rails 70 installed on the inner side of the two long side plates 75 and the slide blocks II 77 installed on the corresponding side of the side plate 78 of the amplitude adjustment box body. Two limit bolts 56 and a proximity switch 57 are installed on the upper connecting plate 58. A cylinder connector connecting seat 73 and a limit block 74 are installed on the outer side of the lower end of each of the two long side plates 75. The receiving seat 73 is connected to the lifting cylinder 55 installed on the lower base plate 79 of the corresponding side amplitude adjustment box. The lifting cylinder 55 drives the up and down moving device 102 to move up and down along the amplitude adjustment box 100. The clamping device 7 is also installed on the clamping mounting seat 72 at the lower end of the U-shaped frame (the closed U-shaped frame structure is more stable, and the combined structure makes the installation simple and feasible. The limit bolt 56 at the top protects the proximity switch 57 and also limits the farthest position of the clamping device 7 from the main beam 42. It is used to align the clamping device with the wooden shaft. The limit block 74 at the lower part of the side plate can limit the closest position of the clamping device 7 to the main beam 42, and protect the bottom of the up and down moving device from hitting the upper pressure roller when it rises to the highest point. The lifting cylinder is used to control the up and down moving device to follow the center of the cloth shaft after clamping the cloth shaft).

[0032] like Figure 1 , Figure 5 , Figure 7 As shown, the clamping device 7 of this invention includes a snapping shaft 93. A clamp 91 for clamping the head of the cloth shaft is installed on the front end face of the snapping shaft 93. Bearings 92 are installed at both ends of the head of the snapping shaft 93. The outer ring of the bearing 92 is installed on the inner hole of the sliding sleeve 94. A connector 96 is installed at one end of the sliding sleeve 94. The connector 96 is connected to the snapping cylinder rod. The snapping cylinder 97 is installed on the outer side of the clamping mounting seat 72. The snapping cylinder 97 pushes the sliding sleeve 94 to slide in the inner hole of the sleeve 95. The sleeve 95 and the clamp The inner side of the head mounting base 72 is connected, and part of its cylindrical body extends into the inner hole of the chuck mounting base, while the other part is exposed on the outside. A photoelectric switch 90 is provided on the outer cylindrical body (the present invention uses the photoelectric switch 90 to detect whether the chuck device 7 has moved into place, controls the amplitude modulation motor 64 to stop, and the flapping cylinder to flap. The flapping cylinder 97 pushes the sliding sleeve 94 to slide in the sleeve 95, thereby driving the flapping shaft 93 to move to clamp the cloth shaft. After the flapping shaft clamps the cloth shaft, it can rotate with the cloth shaft).

[0033] like Figure 1 , Figure 6As shown, the main lead screw transmission mechanism 9 of this invention includes a servo motor 81, a reducer I 83, a reducer II 89, a transmission shaft 86, and a main lead screw 18. The servo motor 81 is mounted on a connecting plate 85 and is directly connected to the input shaft of the reducer I 83 via a coupling III 82. The output shafts on both sides of the reducer I 83 are connected to the transmission shaft 86 via a coupling IV 84. The transmission shaft 86 is connected to the reducer II 89, which is mounted on the outside of the large wall panel, via a coupling IV 84. The output shaft of the reducer II 89 is connected to the main lead screw 18 via a coupling V 88. The shaft of the main lead screw 18 is directly connected. One end of the main lead screw 18 is connected to the longitudinal brace 20 of the upper frame through a bearing seat, and the other end is installed on the lead screw support seat 87. The lead screw support seat 87 is fixed on the large wall plate 12. The shaft of the main lead screw 18 is connected to the lead screw support seat 87 through a pair of rolling bearings and a pair of thrust bearings. The end is equipped with a locking nut for locking (in this way, the servo motor outputs torque through the transmission shaft, the reducer decelerates and changes the transmission direction, the main lead screw drives the load, the transmission accuracy is high, the output torque is large, the structure is simple, and the installation is convenient).

[0034] The working principle and process of this invention are as follows: Before starting the machine, the upper pressure roller device 8 is at the third proximity switch 19 (i.e., the upper limit position), the amplitude adjustment device 10 is at the outer limit position of the main beam 42, and the snapping shaft 93 is in the retracted state.

[0035] When using the device of this invention, first press the "Upper Pressure Roller - Lower" button to send a signal to the servo motor 81. The servo motor 81 starts to run and drives the main lead screw 18 to rotate through the main lead screw transmission mechanism 9. The rotation of the main lead screw 18 drives the main lead screw nut 51 to move downward, thereby driving the upper pressure roller device 8 to move downward. After reaching the second proximity switch 17 (i.e., the middle limit), it automatically stops (waiting for subsequent instructions).

[0036] As the upper pressure roller device 8 moves downward, the operator places the prepared wooden shaft into the gap formed by the support rollers A4 and B6, adjusts its position, and then turns the "lifting cylinder" knob to the "down" position. The lifting cylinder 55 pulls the clamping device 7 downward until it stops when the limit bolt 56 presses against the upper top plate 60. At this time, the proximity switch 57 detects the upper top plate 60 and its indicator light illuminates. The proximity switch 57 sends a running signal to the amplitude modulation motor 64, which starts running and drives the amplitude modulation device 10 to move inward through the amplitude modulation screw 54. When the photoelectric switches 90 on both sides of the clamping device 7 detect the end face of the wooden shaft, they send a signal to the solenoid valves of the amplitude modulation motor 64 and the clamping cylinder 97, controlling the amplitude modulation motor 64 to stop, ending the amplitude modulation action. At the same time, the clamping cylinder 97 starts to move, pushing the clamping shaft 93 to extend and clamp the wooden shaft.

[0037] After the clamping shaft 93 clamps the wooden shaft, the operator needs to turn the "lifting cylinder" knob to the "up" position. The chuck device 7 will then lift the wooden shaft off the support roller surface, and the clamping shaft 93 will be aligned and clamped in place. Then, the operator should quickly turn the "lifting cylinder" knob to the "down" position to press the wooden shaft back onto the support roller, thus completing the alignment and clamping operation of the clamping shaft 93 on the wooden shaft.

[0038] After centering, the operator needs to turn the "cloth-flipping cylinder" knob to the "lift" position. The cloth-flipping cylinder drives the flipping plate to press the cloth onto the wooden shaft. The operator pulls the cloth end over and wraps it around the wooden shaft, nails it in place with steel nails, and then turns the "cloth-flipping cylinder" knob to the "lower" position, and the flipping plate returns to its original position.

[0039] After the flip plate returns to its original position, press the "Upper Pressure Roller - Down" button again. The servo motor 81 will continue to run, driving the upper pressure roller device 8 to move down from the middle limit position until the upper pressure roller 41 presses against the wooden shaft. When the combined force of the pressure of the upper pressure roller 41 and the self-weight of the support roller B 6 equals the set value, the servo motor 81 will stop running, the upper pressure roller device 8 will stop moving, and the "Run" button will be pressed to start winding.

[0040] During operation, the diameter of the fabric shaft gradually increases, pressing the upper pressure roller 41 upwards, thus increasing the pressure. The weighing sensor 30 detects that the pressure is greater than the set value and sends a signal to control the servo motor 81 to run in reverse, causing the upper pressure roller 41 to rise, thereby reducing the pressure of the upper pressure roller 41 on the fabric shaft and maintaining the set value. This process is repeated until the shaft is full and the machine stops.

[0041] Once the fabric shaft is fully wound, the support roller motor stops, the winding action ceases, the weight of the fabric shaft no longer increases, and the servo motor 81 also stops operating. A full-shaft signal is transmitted to the solenoid valves corresponding to the lower pressure roller cylinder 38 and the snap-fit ​​cylinder 97. The solenoid valves control the lower pressure roller cylinder 38 to extend and push the lower pressure roller 35 to lift and press the fabric surface. The snap-fit ​​cylinder 97 retracts, causing the snap-fit ​​shaft 93 to disengage from the wooden shaft. After the retraction is complete, a signal is sent to the lifting cylinder 55 and the amplitude modulation motor 64. The lifting cylinder 55 pulls the clamping device 7 upwards until the bolt on the limit block 74 presses against the lower base plate 79 and stops. The anti-fall cylinder 76 extends and locks the long side plate 75. Simultaneously, the clamping device 7 moves upwards, driving the amplitude modulation device 10 to move outwards until it stops at the outer limit. As the chuck device 7 moves upward, the distance between the upper connecting plate 58 and the upper top plate 60 increases. After the proximity switch 57 can no longer detect the upper top plate 60, it will control the servo motor 81 to continue running, driving the upper pressure roller device 8 to rise until the third proximity switch 19 (i.e., the upper limit) detects the upper pressure roller device 8 and stops again.

[0042] Press and hold the "Exit Fabric" button, the flip cylinder 33 will lift the fabric shaft flipping device 3, and with the operator's assistance, the fabric shaft will flip to exit fabric. After the fabric is exited, release the "Exit Fabric" button, the flip cylinder 33 will pull the fabric shaft flipping device 3 back down, press the "Cut Fabric" button, the fabric will be cut automatically, and the winding will be completed.

[0043] When the weight of the cloth shaft equals or exceeds the set pressure value, but the cloth shaft has not yet reached full weight, the detection pressure of the weighing sensor 30 will remain in an overweight state. This will control the servo motor 81 to drive the upper pressure roller 41 to move upward continuously. The clamping device 7 holds the wooden shaft, and as the center of the cloth shaft changes, the distance between the clamping device 7 and the large crossbeam 42 will increase, while the distance between the upper connecting plate 58 and the upper top plate 60 will decrease until the proximity switch 57 detects the upper top plate 60 and sends a signal to control the servo motor 81 to stop. The upper pressure roller device 8 then stops moving upward. As the diameter of the cloth shaft continues to increase, the distance between the clamping device 7 and the upper pressure roller device 8 will decrease again, while the distance between the upper connecting plate 58 and the upper top plate 60 will increase. When the proximity switch 57 can no longer detect the upper top plate 60, it will control the servo motor 81 to run again, driving the upper pressure roller device 8 to move upward. This process repeats until the shaft is full, and subsequent actions are the same.
