Description

Drum winding machine Technical Field

[0001] This invention belongs to the field of rubber winding, and particularly relates to a drum winding machine. Background Technology

[0002] In the production process of rubber products, rubber strips typically undergo extrusion, cooling, traction, and winding processes, ultimately being stored or further processed in roll form. Among these, the winding stage has a significant impact on the quality of the finished rubber strip. Currently, the industry widely uses drum winding machines for automatic winding of rubber strips. Their basic structure includes a feeding guide mechanism, a traction device, and a rotating winding drum. The continuous rotation of the winding drum winds the rubber strip layer by layer around its surface.

[0003] However, in actual winding, as the rubber strip continuously winds around the winding drum, the winding diameter gradually increases. If the winding machine's drive system uses constant speed control, the linear speed of the rubber strip will increase accordingly. To maintain continuous winding, dynamic tension changes will occur between the traction system and the winding system. Especially for highly elastic, low-modulus rubber materials, this gradually increasing tension can easily cause the rubber strip to be overstretched during winding, resulting in irreversible plastic deformation or elastic hysteresis. On the one hand, the stretched rubber strip will shrink back after unwinding, causing the roll to become loose, misaligned between layers, or even collapse. On the other hand, localized tension concentration may also cause the rubber strip to become narrower and thicker, seriously affecting its dimensional accuracy and physical properties.

[0004] Therefore, there is an urgent need to develop a drum winding machine that can change the winding connection point in real time during the winding process to effectively suppress the stretching deformation of the rubber strip. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a drum winding machine that changes the winding connection point in real time during the winding process to effectively suppress the stretching deformation of the rubber strip.

[0006] The drum winding machine includes an outer frame, a winding position adjustment device, an inner frame, and a winding device. The winding position adjustment device is installed in the upper part of the outer frame. The winding position adjustment device includes a horizontal moving structure, a material straightening structure, a feeding structure, a tensioning structure, and an adaptive winding point adjustment structure. The horizontal moving structure is used to change the horizontal position of the winding point. The material straightening structure straightens the material before it is conveyed. The feeding structure is used to convey the material horizontally. The tensioning structure keeps the material taut during the winding process. The adaptive winding point adjustment structure automatically changes the position of the winding point when the wound material becomes thicker. The inner frame is positioned inside the outer frame and has the function of holding the winding drum. The winding device is installed between the front and rear walls of the inner frame and winds the material by rotation.

[0007] To further explain, the horizontal moving structure includes a horizontal moving module, an adapter plate, and a first mounting plate. The horizontal moving module is horizontally mounted on the upper part of the outer frame, extending forward and backward. The adapter plate is mounted on the slider of the horizontal moving module, and the first mounting plate is horizontally mounted on the top left and right sides of the adapter plate.

[0008] To further explain, the material straightening structure includes a feeding plate, an electric pressure roller, and a straightening roller. The feeding plate, electric pressure roller, and straightening roller are arranged sequentially from right to left on the top right side of the first mounting plate. The feeding plate has a through hole in the middle. The installation angle of the electric pressure roller can be adjusted. There are three rows of straightening rollers, which are combined to form a triangular feeding channel.

[0009] To further explain, the feeding structure includes an electric conveyor wheel, an upper limit wheel, side guide plates, and an auxiliary conveyor wheel. The electric conveyor wheel is installed on the top of the first mounting plate on the left side of the crawler wheel. The upper limit wheel is rotatably installed above the electric conveyor wheel. The distance between the upper limit wheel and the electric conveyor wheel can be adjusted. Side guide plates are provided on both the front and rear sides of the left side of the first mounting plate, and auxiliary conveyor wheels are installed on the sides of the side guide plates.

[0010] To further explain, the straightening structure includes an electric swing arm, a straightening wheel, and a limiting frame. An electric swing arm that tilts downwards to the right is mounted on the side of the side guide plate. A straightening wheel that extends forward and backward is rotatably mounted at the end of the electric swing arm. A limiting frame is provided on the top of the first mounting plate at the straightening wheel. The limiting frame limits the forward and backward movement of the material passing through.

[0011] To further explain, the adaptive adjustable take-up point structure includes a sliding mounting plate, pulleys, steering wheels, a sliding rod, a threading head, a first spring, and adjusting screws. The sliding mounting plate has guide grooves that slope upwards and to the left on opposite sides. Pulleys are located on both the front and rear sides of the sliding mounting plate, and these pulleys are engaged in the guide grooves, allowing the sliding mounting plate to slide smoothly against the side guide plate. Steering wheels are rotatably mounted on the upper and lower surfaces of the right side of the sliding mounting plate. A sliding rod is slidably mounted on the lower part of the sliding mounting plate, with a threading head at the bottom. Adjusting screws are threadedly connected to both the front and rear sides of the upper part of the sliding rod, and a first spring connects the inner end of the adjusting screw to the upper part of the sliding rod.

[0012] Further explanation: The winding device includes a second mounting plate, a sliding plate, a cylinder, a winding motor, a drive shaft, a chuck, grippers, a second spring, and a winding cylinder. The second mounting plate is installed on the lower sides of both the front and rear walls of the inner frame. Sliding plates are horizontally slidably mounted on the top of each of the second mounting plates. A cylinder is installed at the bottom of the second mounting plate, and the telescopic end of the cylinder is connected to the sliding plate. A winding motor is mounted on the top of one of the sliding plates. A drive shaft is rotatably mounted on the top of each sliding plate. The output shaft of the winding motor is connected to the end of its adjacent drive shaft. A chuck is connected to the inner end of each drive shaft. A ring of grippers is rotatably mounted on the inner side of the chuck. A second spring connects the grippers to the chuck. Grooves are formed on the end faces of the grippers. The outer side of the grippers is longer than the inner side. The inner end of the grippers is tapered. A winding cylinder is fixed between the grippers.

[0013] Further explanation includes a feeding guide mechanism. The feeding guide mechanism is located on the right side of the outer frame. The feeding guide mechanism includes a feeding frame, feeding wheels, guide frames, counterweight wheels, bottom limit wheels, side limit wheels, a swing arm, and a limiting pressure wheel. The feeding frame is installed on the right side of the outer frame. Feeding wheels are rotatably installed on the top left and right sides of the feeding frame. A guide frame is vertically installed in the middle of the feeding frame. A counterweight wheel is vertically slidably connected to the guide frame. A bottom limit wheel is rotatably installed on the left side of the left feeding wheel. Side limit wheels are vertically rotatably installed on the feeding frame in front of and behind the bottom limit wheel. A swing arm is rotatably installed on the feeding frame on the left side of the right feeding wheel. A limiting pressure wheel is rotatably installed at the end of the swing arm, and the limiting pressure wheel presses on top of the feeding wheel.

[0014] To further explain, it also includes a film-coating device. The film-coating device is installed on the top of the outer frame. The film-coating device includes an upper bracket, a sliding frame, a sleeve, and a handle. The upper bracket is installed on the top of the outer frame. The sliding frame is slidably connected to the side of the upper bracket. The lower part of the sliding frame is detachably connected to the sleeve. A handle is provided on the left side of the sliding frame.

[0015] The beneficial effects of this invention are as follows: Through the coordination of a material straightening structure, a feeding structure, a straightening structure, and an adaptive adjustment take-up point structure, the rubber strip first passes through the straightening structure, being straightened before being conveyed, thus ensuring the rolled rubber strip is in a straight state. During the conveying process, the straightening structure keeps the rubber strip taut, maintaining the winding force. The horizontal movement structure can change the front and rear horizontal position of the take-up point, allowing the rubber strip to be evenly wound around the surface of the take-up cylinder. When more rubber strip is wound onto the take-up cylinder, the rubber strip wound on the take-up cylinder pushes the sliding rod to move outward, while the sliding mounting plate slides outward within the guide groove. This allows the threading head to automatically adapt to the increased amount of rubber strip on the take-up cylinder, effectively suppressing the stretching deformation of the rubber strip during the winding process. During the rubber strip winding process, the feed roller, counterweight roller, bottom limiting roller, side limiting roller, and limiting pressure roller guide and limit the rubber strip. The winding speed of the rubber strip can be better controlled according to the height of the counterweight roller. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0028] Example: A drum winding machine, as shown in Figures 1-8, includes an outer frame 1, a winding position adjustment device 2, an inner frame 3, and a winding device 4. The bottom of the outer frame 1 is equipped with wheels with brakes for easy movement. The left side of the outer frame 1 has an opening, and the side walls of the outer frame 1 are all equipped with protective netting. The winding position adjustment device 2 is installed in the upper part of the inner part of the outer frame 1. The winding position adjustment device 2 includes a horizontal moving structure, a material straightening structure, a feeding structure, a straightening structure, and an adaptive winding point adjustment structure. The material to be wound passes through the material straightening structure, feeding structure, straightening structure, and adaptive winding point adjustment structure from right to left. The horizontal moving structure is used to change the horizontal position of the winding point so that the material can be evenly wound on the surface of the winding drum 49. The material straightening structure... Before material is conveyed, it is straightened to ensure that the wound material is in a straight state and to ensure the flatness of the wound material. The feeding structure is used to convey material horizontally, and the material is conveyed from right to left by rotation. The straightening structure keeps the material taut during the winding process. The adaptive adjustment winding point structure automatically changes the winding point position when the wound material becomes thicker, so as to prevent the material from deforming due to dynamic tension during the winding process. An inner frame 3 is positioned inside the outer frame 1. The height of the inner frame 3 is lower than that of the outer frame 1. The side walls of the inner frame 3 are equipped with protective nets. The front and rear walls of the inner frame 3 are equipped with concave support arms. The take-up cylinder 49 is placed between the support arms. A winding device 4 is installed between the front and rear walls of the inner frame 3 to wind the material by rotation.

[0029] Compared with existing technologies, the drum winding machine sequentially passes the end of the rubber strip through a material straightening structure, a feeding structure, a straightening structure, and an adaptive adjustment winding point structure. The conveying state of the rubber strip is shown in Figure 3. During the winding process, the rubber strip first passes through the straightening structure, which straightens the strip before conveying it, ensuring the wound rubber strip is straight. During conveying, the straightening structure keeps the rubber strip taut, maintaining the winding force. The horizontal movement structure can change the front and rear horizontal position of the winding point, allowing the rubber strip to be evenly wound around the surface of the winding drum 49. The adaptive adjustment winding point structure automatically changes the winding point position when the wound rubber strip thickens, causing the rubber strip to deform due to dynamic tension during the winding process.

[0030] As shown in Figure 3, the horizontal moving structure includes a horizontal moving module 21, a transition plate 22, and a first mounting plate 23. The horizontal moving module 21 is horizontally fixedly installed on the upper part of the outer frame 1 by bolts extending forward and backward. Referring to Figure 3, the horizontal moving module 21 adopts a motor and belt conveyor, which enables the slider of the horizontal moving module 21 to move forward and backward continuously. The transition plate 22 is fixedly installed on the slider of the horizontal moving module 21 by bolts. The first mounting plate 23 is horizontally fixedly installed on the top of the transition plate 22 by bolts extending left and right. The material straightening structure, feeding structure, tensioning structure, and adaptive adjustment winding point structure are all installed on the first mounting plate 23. By changing the position of the components on the first mounting plate 23 through the horizontal moving module 21, the rubber strip moves forward and backward, so that the rubber strip is evenly wound around the surface of the take-up cylinder 49.

[0031] As shown in Figures 3 and 4, the material straightening structure includes a feed plate 24, an electric pressure roller 25, and a straightening roller 26. The feed plate 24, electric pressure roller 25, and straightening roller 26 are arranged sequentially from right to left on the top right side of the first mounting plate 23. The feed plate 24 has a through hole in the middle, through which the rubber strip passes. The edges of the holes on the feed plate 24 are rounded to facilitate the insertion of the rubber strip. The installation angle of the electric pressure roller 25 is adjustable, pressing against the upper surface of the rubber strip. The straightening roller 26 has three rows, forming a triangular feeding channel through which the rubber strip passes. When the rubber strip passes through the feed plate 24, it undergoes its first straightening process. Subsequently, the rubber strip passes through the rotating electric pressure roller 25, which straightens the small wrinkles on the surface of the rubber strip. Finally, the straightening roller 26 straightens the rubber strip from three directions and also assists in conveying the rubber strip.

[0032] As shown in Figures 3 and 4, the feeding structure includes an electric conveyor wheel 27, an upper limit wheel 28, a side guide plate 29, and an auxiliary conveyor wheel 210. The electric conveyor wheel 27 is mounted on the top of the first mounting plate 23 to the left of the crawler wheel 26. The electric conveyor wheel 27 consists of a motor and a roller. The roller is mounted on the output shaft of the electric conveyor wheel 27 and is located above the rubber strip. The upper limit wheel 28 is rotatably mounted above the electric conveyor wheel 27. Referring to Figure 3, the upper limit wheel 28 is slidably connected above the roller. The height of the upper limit wheel 28 is adjusted by a screw. Side guide plates 29 are provided on both the front and rear sides of the left side of the first mounting plate 23. The auxiliary conveyor wheel 210 is mounted on the side of the side guide plate 29 and is located below the rubber strip. During the rubber strip winding process, the electric conveyor wheel 27 is controlled to rotate counterclockwise, while the auxiliary conveyor wheel 210 is controlled to rotate clockwise. The upper limit wheel 28 limits the upper part of the rubber strip, thereby achieving stable conveying of the rubber strip.

[0033] As shown in Figures 3 and 4, the straightening structure includes an electric swing arm 211, a straightening wheel 212, and a limiting frame 213. An electric swing arm 211 inclined to the lower right is installed on the side of the side guide plate 29. The straightening wheel 212 extending forward and backward is rotatably installed at the end of the electric swing arm 211. The straightening wheel 212 is below the rubber strip. A limiting frame 213 is provided on the top of the first mounting plate 23 at the straightening wheel 212. The rubber strip passes through the limiting frame 213, and the limiting frame 213 limits the forward and backward movement of the passing rubber strip. During the conveying of the rubber strip, the electric swing arm 211 drives the straightening wheel 212 to swing upward and contact the bottom of the rubber strip. If the rubber strip is not straightened, the straightening wheel 212 can tighten the slack rubber strip, so that the rubber strip can be conveyed stably.

[0034] As shown in Figures 3-5, the adaptive adjustable take-up point structure includes a sliding mounting plate 215, pulleys 216, steering wheels 217, sliding rods 218, threading heads 219, a first spring 2120, and adjusting screws 2121. The inner side of the sliding mounting plate 215 has two guide grooves 214 inclined upwards to the left. Pulleys 216 are provided on both the front and rear sides of the sliding mounting plate 215, and the pulleys 216 are engaged in the guide grooves 214, allowing the sliding mounting plate 215 to slide in connection with the side guide plate 29. Steering wheels 217 are rotatably mounted on the upper and lower surfaces of the right side of the sliding mounting plate 215. The steering wheels 217 are used to limit the movement of the passing rubber strip. A sliding rod 218 is slidably mounted on the lower part of the sliding mounting plate 215, and a threading head 219 is provided at the bottom of the sliding rod 218. The end passes through the threaded head 219. The upper front and rear sides of the sliding rod 218 are connected to adjusting screws 2121 by threads. The inner end of the adjusting screw 2121 is connected to the upper part of the sliding rod 218 by a first spring 2120. By turning the adjusting screw 2121, the front and rear position of the sliding rod 218 can be adjusted. During the rubber strip winding process, the horizontal moving structure drives the sliding rod 218 to move back and forth to wind the rubber strip. When more rubber strip is wound on the take-up cylinder 49, the rubber strip wound on the take-up cylinder 49 pushes the sliding rod 218 to move outward. At the same time, the sliding mounting plate 215 slides outward in the guide groove 214. In this way, the threaded head 219 can automatically adapt to the increased rubber strip on the take-up cylinder 49, so that the rubber strip can effectively suppress the stretching deformation of the rubber strip during the winding process.

[0035] As shown in Figures 7 and 8, the winding device 4 includes a second mounting plate 41, a sliding plate 42, a cylinder 43, a winding motor 44, a drive shaft 45, a chuck 46, grippers 47, a second spring 48, and a winding cylinder 49. The second mounting plate 41 is horizontally mounted on the lower sides of both the front and rear walls of the inner frame 3 via bolts. A sliding plate 42 is horizontally mounted on the top of the second mounting plate 41 via a slide rail and a slider. A cylinder 43 is horizontally mounted on the bottom of the second mounting plate 41 via bolts. The extension and retraction ends of the cylinder 43 are connected to the sliding plate 49. 2. The connection is made so that the sliding plate 42 moves left and right by the cylinder 43. The top of one of the sliding plates 42 is fixedly mounted with a take-up motor 44 by bolts. The top of each sliding plate 42 is rotatably mounted with a drive shaft 45. The output shaft of the take-up motor 44 is connected to the end of the adjacent drive shaft 45. The inner end of each drive shaft 45 is connected to a chuck 46. Three grippers 47 are rotatably mounted on the inner side of the chuck 46 at even intervals. A second spring 48 is connected between the grippers 47 and the chuck 46. The end face of the grippers 47 has a concave opening. The outer side of the gripper 47 is longer than the inner side. The inner end of the gripper 47 is conical. A take-up cylinder 49 is fixed between the grippers 47. The conical grippers 47 can be easily inserted into the take-up cylinder 49. The two ends of the take-up cylinder 49 are placed on the support arms on the front and rear walls of the inner frame 3. Then, the control cylinder 43 extends, driving the chuck 46 and grippers 47 to move inward, so that the inside of the grippers 47 is inserted into the take-up cylinder 49. At this time, the grippers 47 swing outward, the second spring 48 is compressed, and the inside of the grippers 47 is locked in place. The inner wall of the material cylinder 49 is used to fix it. Then, the take-up motor 44 is controlled to rotate, which drives the transmission shaft 45 to rotate, which in turn drives the chuck 46 and the gripper 47 to rotate, thereby driving the take-up cylinder 49 to rotate to wind up the rubber strip. After the rubber strip is wound up on the take-up cylinder 49, the take-up motor 44 is controlled to stop working. Then, the cylinder 43 is controlled to shorten, so that the chuck 46 and the gripper 47 move outward away from the take-up cylinder 49. The gripper 47 is reset under the action of the second spring 48. Then, the wound-up cylinder 49 is removed.

[0036] As shown in Figure 9, to better wind up the rubber strip, a feeding guide mechanism 5 is also included. The feeding guide mechanism 5 is placed on the right side of the outer frame 1. The feeding guide mechanism 5 includes a feeding frame 51, a feeding wheel 52, a guide frame 53, a counterweight wheel 54, a bottom limiting wheel 55, a side limiting wheel 56, a swing arm 57, and a limiting pressure wheel 58. The feeding frame 51 is installed on the right side of the outer frame 1. Feeding wheels 52 are rotatably mounted on the top left and right sides of the feeding frame 51. A guide frame 53 is vertically mounted in the middle of the feeding frame 51. A counterweight wheel 54 is vertically slidably connected to the guide frame 53. The rubber strip passes under the counterweight wheel 54. A bottom limiting wheel 55 is rotatably mounted on the left side of the left feeding wheel 52. The rubber strip is above the bottom limiting wheel 55. Side limiting wheels 56 are vertically rotatably mounted on the feeding frame 51 at the front and rear of the bottom limiting wheel 55. The rubber strip passes under the side limiting wheel 56. The feed rollers 56 pass between each other. A swing arm 57 is rotatably mounted on the feed frame 51 to the left of the right feed roller 52. A limiting pressure roller 58 is rotatably mounted at the end of the swing arm 57, pressing down on the feed roller 52. Before entering the winding position adjustment device 2, the rubber strip passes around the feed roller 52, the counterweight roller 54, and the side limiting roller 56. For details of the passing around, please refer to Figure 9. During the winding process of the rubber strip, the feed roller 52, the counterweight roller 54, the bottom limiting roller 55, the side limiting roller 56, and the limiting pressure roller 58 guide and limit the rubber strip, so that the rubber strip can enter the winding position adjustment device 2 better. At the same time, according to the height of the counterweight roller 54, the lower the height of the counterweight roller 54, the slower the winding speed, and the need to increase the winding speed. The higher the height of the counterweight roller 54, the faster the winding speed, and the need to decrease the winding speed. This is to better control the winding speed of the rubber strip.

[0037] As shown in Figure 10, a film-coating device 6 is also included to facilitate subsequent work. The film-coating device 6 is installed on the top of the outer frame 1. The film-coating device 6 includes an upper support 61, a sliding frame 62, a sleeve 63, and a handle 64. The upper support 61 is concave and is fixed to the top of the outer frame 1 by bolts at both ends of the bottom. The sliding frame 62 is slidably connected to the side of the upper support 61 by a slide rail and a slider. The sleeve 63 is detachably connected to the lower part of the sliding frame 62. The wrapping film is placed on the sleeve 63. The handle 64 is provided on the left side of the sliding frame 62. The position of the sliding frame 62 is adjusted by the handle 64, so that the position of the wrapping film is changed. After the rubber strip is wrapped in the receiving cylinder 49, the end of the wrapping film is placed on the outer surface of the receiving cylinder 49. Then the receiving cylinder 49 is rotated to wrap the wrapping film on its surface to protect the wrapped rubber strip.
