Description

Technical Field

[0001] This application relates to the field of waterproof membrane processing technology, and in particular to an automatic membrane feeding mechanism. Background Technology

[0002] Roll material cutting refers to the process of cutting and trimming rolled materials, such as waterproof rolls, thermal insulation rolls, and decorative rolls, according to the required dimensions and shapes for construction. Nowadays, in order to meet the needs of convenient construction, waterproof rolls are cut into rolls of different lengths according to the dimensions of the on-site construction during the cutting process, so as to facilitate subsequent construction needs. In order to meet market demand, it is necessary to automatically cut and roll waterproof rolls during the roll making process.

[0003] Furthermore, existing patent publication number CN220840380U discloses a waterproof roll material cutting device, but the above device has the following shortcomings in actual use:

[0004] When the roll material is placed horizontally on the workbench, after the roll material is cut, since the roll material was initially wound on the spool, the cut roll material will curl up. Therefore, a special smoothing device is needed to smooth it out to prevent the roll material from wrinkling during the rolling process. In order to prevent the roll material from wrinkling during the rolling process and to reduce the installation of unnecessary parts, this solution proposes an automatic roll material feeding mechanism. Utility Model Content

[0005] To address the issue of wrinkles that easily occur after cutting during the roll forming process, this application provides an automatic roll feeding mechanism.

[0006] The automatic roll material feeding mechanism provided in this application adopts the following technical solution:

[0007] An automatic roll material feeding mechanism includes a frame, a drive assembly at the top of the frame, a cutting assembly for cutting the roll material on one side of the frame, a rolling assembly on one side of the cutting assembly, and a coating assembly on one side of the frame below the cutting assembly.

[0008] By adopting the above technical solution, the frame serves as the supporting structure of the entire equipment, providing an installation foundation and a stable working platform for other components. The drive component is installed on the top of the frame, providing power for operations such as moving, cutting, and rolling the roll material, ensuring the normal operation of all parts of the equipment. The cutting component, located on one side of the frame, cuts the roll material according to requirements to obtain roll material of appropriate size. The rolling component, located on one side of the cutting component, can wind the cut roll material into a roll shape for easy storage and transportation. The coating component, located on one side of the frame and below the cutting component, is used to coat the surface of the cut roll to meet the requirements of rolling.

[0009] Preferably, the cutting assembly includes a support platform fixed to one side of the frame. A rectangular hole is provided at one end of the support platform away from the frame, and a cutting groove is provided at one end of the support platform below the rectangular hole. A base plate is fixedly installed at the bottom of the support platform. A first electric cylinder is fixedly installed in the middle of one side of the base plate. A push plate is fixedly installed at the telescopic end of the first electric cylinder. A blade that is inserted into the cutting groove is fixedly installed on one side of the push plate. A limiting rod that movably penetrates the base plate is symmetrically fixed on one side of the push plate.

[0010] By adopting the above technical solution, the support platform is fixed on one side of the frame, providing an installation base and support for other parts of the cutting assembly. The rectangular holes and cutting grooves on the platform provide the necessary space and structure for subsequent cutting operations. The base plate is fixedly installed at the bottom of the support platform to install and fix parts such as the first electric cylinder, providing a stable installation plane and ensuring the stability of the cutting action. The first electric cylinder is fixed in the middle of one side of the base plate. Through the telescopic movement of the telescopic end, it provides power to the push plate, thereby driving the blade to perform the cutting operation. The limiting rod is symmetrically fixed on one side of the push plate and moves through the base plate, which restricts the direction of movement of the push plate and ensures that the push plate moves in a straight line under the drive of the first electric cylinder, so that the blade can cut accurately and improve cutting accuracy and stability.

[0011] Preferably, a first support frame is fixed on the side of the frame away from the support platform, and an air shaft is provided at the end of the first support frame. A second support frame is fixed on the side of the frame close to the first support frame, and a locking clip is provided at the end of the second support frame.

[0012] By adopting the above technical solution, the air shaft is set at the end of the first support frame. Its main function is probably to install and fix the roll material. The roll material can be easily loaded and unloaded by air expansion, and the roll material can be kept stable during operation. The locking clip is set at the end of the second support frame to lock and fix the roll material installed on the air shaft, ensuring that the roll material will not loosen or shift during equipment operation, thus ensuring the stability and safety of the operation.

[0013] Preferably, the drive assembly includes a servo motor fixed above one side of the frame, and a first drive roller with both ends movably penetrating the frame is fixed at the output end of the servo motor. A rotating column is fixed at one end of the first drive roller, and a belt is rotatably connected to the rotating column.

[0014] By adopting the above technical solution, the servo motor is fixedly installed on the upper side of the frame as a power source to provide power to the entire drive assembly, enabling the equipment to operate. The first drive roller is fixedly connected to the output end of the servo motor, with both ends movably passing through the frame. It rotates under the drive of the servo motor to drive the roll material to move. The rotating column is fixed to one end of the first drive roller and rotates with the rotation of the first drive roller, providing a connection and support point for the belt and playing the role of transmitting power. The belt is rotatably connected to the rotating column, which can transmit the power of the first drive roller to other components that require power, realizing the transmission and distribution of power.

[0015] Preferably, a rectangular groove is provided on the side of the frame, and a first fixing block is fixedly provided on the side of the frame near the lower part of the rectangular groove. The first fixing block is threadedly connected to a threaded rod, and a second fixing block is rotatably connected to the top end of the threaded rod. A slider that is slidably connected to the rectangular groove is fixedly provided at the end of the second fixing block, and a second drive roller is movably passed through the slider.

[0016] By adopting the above technical solution, a rectangular groove is opened on the side of the frame to provide a sliding track for the slider, allowing the slider to move along a fixed path, thereby adjusting the position of the second drive roller. The threaded rod is threadedly connected to the first fixed block, and the vertical displacement can be achieved by rotating the threaded rod, thereby driving the second fixed block and the slider to move up and down to adjust the height of the second drive roller. The second drive roller moves through the slider to assist in the conveying of the roll material, and its height can be adjusted by the sliding of the slider in the rectangular groove to adapt to different roll material processing needs.

[0017] Preferably, a plurality of third fixing blocks are fixedly provided on the top of the support platform, and a limiting roller moves through the third fixing blocks.

[0018] By adopting the above technical solution, the limiting roller moves through the third fixed block, and plays a limiting and guiding role in the roll material during the roll material conveying process, ensuring that the roll material moves along the predetermined route, preventing it from deviating, and improving the cutting accuracy.

[0019] Preferably, the winding assembly includes a side plate fixed to one side of the support platform, a horizontal shaft movably passing through the end of the side plate, a rotating column fixed at one end of the horizontal shaft and rotatably connected to a belt, a disc fixed at the other end of the horizontal shaft, a fourth fixing block fixed at the middle of one end of the disc, two limiting posts movably passing through the fourth fixing block, an installation head fixed at the end of each of the two limiting posts and slidably connected to the disc at one end, compression springs for abutting the installation head and the fourth fixing block at their two ends respectively on the outer peripheral surface of each of the two limiting posts, and a roller located vertically below the rectangular hole inserted into the installation head.

[0020] By adopting the above technical solution, the horizontal shaft moves through the end of the side plate, playing the role of transmitting power. The power from the belt is transmitted to the disc through the rotating column, causing the disc to rotate. One end of the rotating column is fixed to the horizontal shaft, and the other end is rotatably connected to the belt, responsible for transmitting the rotational power of the belt to the horizontal shaft. The fourth fixing block is fixed in the middle of one end of the disc, used to install and support the limiting column, providing a base point for the limiting column to move. The limiting column moves through the fourth fixing block, restricting the position and direction of movement of the mounting head, ensuring that the mounting head moves within a certain range, and ensuring the stability of the roller installation and use. The compression spring is used to provide lateral force. The mounting head is used to insert the roller, fixing the roller on the disc, and under the action of the limiting column and the compression spring, the stability and flexibility of the roller installation are ensured.

[0021] Preferably, the coating assembly includes a liquid outlet tank fixed to the bottom of the support platform, a base fixed to the bottom of the liquid outlet tank, a second electric cylinder located on the top of the base on one side of the liquid outlet tank, a top plate at the telescopic ends of the two second electric cylinders, a coating plate fixed to one end of the top plate located at the bottom of the liquid outlet tank, the coating plate being in contact with the outer peripheral surface of the roller, and a groove being formed in the middle of the bottom of the coating plate.

[0022] By adopting the above technical solution, the liquid outlet tank is fixed at the bottom of the support platform to store the coating liquid and provide a source of coating for the coating operation of the roll material. The second electric cylinder is set at the top of the base and located on one side of the liquid outlet tank. Its extension and retraction can drive the top plate to move, thereby adjusting the position of the coating plate. One end of the coating plate is fixed on the top plate and located at the bottom of the liquid outlet tank, and is in contact with the outer peripheral surface of the roller. It is responsible for evenly applying the coating to the surface of the roll material that has passed through the roller. The drip groove is opened in the middle of the bottom of the coating plate so that the coating can be returned.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the cooperation of the coating component, the rolling component, and the drive component, the roll material is vertically conveyed and cut. Even if the end is squeezed, the end can still be smoothly adhered and wound by the roller after re-conveyance. This linkage device does not require an additional smoothing device, which reduces the installation of unnecessary parts and effectively prevents wrinkles from appearing during the roll material rolling process, thus ensuring the processing quality of the roll material.

[0025] 2. Through the coordinated operation of the cutting component, the rolling component, and the coating component, the first drive roller conveys the roll material, and the electric cylinder controls the blade cutting, etc., the roll material can be cut into rolls according to different length requirements and rolled into cylinders, which greatly facilitates subsequent construction and precisely meets the market demand for waterproof roll material to be processed according to the on-site construction dimensions.

[0036] The following is in conjunction with the appendix Figure 1 - Figure 5 This application will be described in further detail.

[0037] The device's "up, down, left, right" perspectives are... Figure 1 The orientation of the attached diagram is the reference.

[0038] This application discloses an automatic roll material feeding mechanism.

[0039] Reference Figure 1-2As shown, an automatic roll material feeding mechanism includes a frame 1. A cutting assembly for cutting the roll material is provided on one side of the frame 1. The cutting assembly includes a support platform 16 fixedly mounted on one side of the frame 1. A rectangular hole 1602 is vertically opened at the end of the support platform 16 away from the frame 1. A cutting groove 1601 is opened on the upper side of the inner side of one end of the support platform 16. The cutting groove 1601 is located vertically below the rectangular hole 1602. A base plate 25 with symmetrically opened round holes on both sides is fixedly installed near the middle of the bottom of the support platform 16. The middle of one side of the base plate 25 is fixedly connected to the mounting seat of the first electric cylinder 26. The telescopic end of the first electric cylinder 26 is fixedly connected to a push plate 27 whose top is slidably connected to the bottom of the support platform 16. A blade 28 is fixedly installed in the middle of the side of the push plate 27 away from the first electric cylinder 26. The blade 28 is inserted into the cutting groove 1601. Limiting rods 29 that movably pass through the round holes opened on both sides of one side of the push plate 27 are symmetrically fixedly connected.

[0040] The first electric cylinder 26 is connected to an external PLC controller and servo driver. The telescopic end of the first electric cylinder 26 is connected to the push plate 27. The PLC controller drives the first electric cylinder 26 to telescopically extend and retract through the servo controller, which in turn drives the push plate 27 to move and causes the top of the push plate 27 to slide along the bottom of the support platform 16, thereby allowing the blade 28 to be inserted into the cutting groove 1601 to achieve transverse cutting of the roll material. The limiting rod 29 serves to limit the direction of movement of the push plate 27.

[0041] Reference Figure 1 As shown, a first support frame 2 is fixedly connected to the middle position of the side of the frame 1 away from the support platform 16. An air shaft 3 is fixedly installed on the inner side of the end of the first support frame 2 away from the frame 1. A second support frame 4 is fixedly connected to the middle position of the side of the frame 1 close to the first support frame 2. A locking clip 5 is fixedly installed on the end of the second support frame 4 away from the frame 1.

[0042] It should be noted that the air shaft 3 and the locking head 5 are the parts disclosed in the existing patent publication number CN217894602U. The air shaft 3 and the locking head 5 clamp the roll material in opposite directions. During operation, the air shaft 3 and the locking head 5 cooperate with each other. The air shaft 3 can make close contact with the inner hole of the roll material by means of inflation and expansion, providing support force. The locking head 5 fixes and locks the other end of the roll material. Through the opposing clamping action of the two, the roll material is firmly fixed to facilitate subsequent cutting and other operations.

[0043] Reference Figure 1 , Figure 3As shown, the system includes a frame 1, with a drive assembly on top of the frame 1. The drive assembly includes a servo motor 6, whose mounting base is fixedly installed on one side of the frame 1 by bolts. The output end of the servo motor 6 is fixedly connected to a first drive roller 7, both ends of which movably penetrate the frame 1. A rotating column 8 is fixedly connected to the end of the first drive roller 7 near the frame 1. A belt 9 is rotatably connected to the rotating column 8. The outer circumferential surface of the rotating column 8 has toothed grooves adapted to the protruding inner circumferential surface of the belt 9. A rectangular slot 10 is provided on the upper side of the frame 1. A first fixing block 11 with a threaded hole in the middle is fixedly connected to one side of the bottom end of the groove 10. A threaded rod 12 is threadedly connected to the first fixing block 11 inside the threaded hole. A second fixing block 13, which is fixedly connected to the top of the threaded rod 12, is rotatably connected to the top of the threaded rod 12. The slider 14 is slidably connected to the rectangular groove 10. A circular hole is opened inside the slider 14. A second drive roller 15 moves through the slider 14 inside the circular hole. At least two third fixing blocks 17 are fixedly installed on the top of the support platform 16. Limiting rollers 18 move through the multiple third fixing blocks 17.

[0044] It should be noted that the servo motor 6 uses a Guangjin servo motor control and drive integrated kit. After powering the servo motor 6, the controller matched with the servo motor 6 starts the servo motor 6. The servo motor 6 drives the first drive roller 7 to rotate, and the first drive roller 7 drives the rotating column 8 to rotate with it. Then, the waterproof roll material to be waterproof is placed between the first drive roller 7 and the second drive roller 15. By rotating the threaded rod 12, under the action of the first fixed block 11, the second fixed block 13 and the slider 14 are driven to move upward along the vertical direction of the rectangular groove 10, thereby changing the distance between the first drive roller 7 and the second drive roller 15 until the roll material generates friction with the outer peripheral surface of the first drive roller 7. The connection method of the servo motor 6, the connecting wire and the control equipment is existing technology and mature, so the specific connection relationship will not be described in detail. It can be used by installing the existing connection assembly.

[0045] Reference Figure 1 , Figure 5As shown, a winding assembly is provided on one side of the cutting assembly. The winding assembly includes a side plate 19 fixedly installed on the middle position of one side of the support platform 16. A circular hole is opened at the end of the side plate 19, and a horizontal shaft 20 is movably inserted through the circular hole. One end of the horizontal shaft 20 is fixedly connected to another rotating column 8 that is rotatably connected to the belt 9. The other end of the horizontal shaft 20 is fixedly connected to a disc 21. A fourth fixing block 2101 with a circular hole on its side is fixedly connected to the center position of one end of the disc 21. The fourth fixing block 2101 is located in the circular hole and movably inserted through two... Each of the two limiting posts 23 has a mounting head 22 fixedly connected to its end, with one end of the mounting head 22 slidably connected to one end of the surface of the disc 21. The other end of the mounting head 22 is hemispherical. Compression springs 24 are fitted on the outer peripheral surfaces of the two limiting posts 23. One end of the compression spring 24 abuts against the mounting head 22, and the other end of the compression spring 24 abuts against the fourth fixing block 2101. The mounting head 22 is inserted into a roller 30 located vertically below the rectangular hole 1602, and the outer peripheral surface of the mounting head 22 is in contact with the inner peripheral surface of the roller 30.

[0046] Servo motor 6 drives the first drive roller 7 to rotate. The rotating column 8 on the first drive roller 7 is driven by belt 9 to drive another rotating column 8 connected to one end of the horizontal shaft 20 in the winding assembly to rotate, thereby causing the horizontal shaft 20 to rotate. The horizontal shaft 20 drives the disc 21 at the other end to rotate. The fourth fixed block 2101 at the center of the disc 21 is connected to the mounting head 22 by two limit posts 23. The mounting head 22 moves with the disc 21 when it rotates. One end of the mounting head 22 is hemispherical and is inserted into the roller 30 located vertically below the rectangular hole 1602. The outer circumferential surface of the mounting head 22 is in contact with the inner circumferential surface of the roller 30. At this time, the compression spring 24 is compressed, so that the outer circumferential surface of the mounting head 22 and the inner circumferential surface of the roller 30 generate a squeezing force, thereby driving the roller 30 to rotate to realize winding.

[0047] It should be noted that the formula for calculating the elastic force of the compression spring 24 is F = kx, where F represents the spring force, kx represents the spring constant (the magnitude of the elastic force generated by the spring under force per unit length), and x represents the spring compression (the displacement distance of the spring from its original state to its compressed state). The elastic force of the compression spring 24 can be calculated using this formula.

[0048] Reference Figure 1 , Figure 4As shown, a coating assembly is provided on one side of the frame 1 below the cutting assembly. The coating assembly includes a liquid outlet tank 32, which can be filled with water-emulsion asphalt adhesive. The top of the liquid outlet tank 32 is fixedly connected to the bottom of the support platform 16. A base 31 is fixedly connected to the bottom of the liquid outlet tank 32. A second electric cylinder 33 is symmetrically fixedly installed on the top of the base 31 on one side of the liquid outlet tank 32. The telescopic ends of the two second electric cylinders 33 are fixedly connected to the bottom middle of one end of the top plate 34. A coating plate 35 is fixedly connected to the other end of the top plate 34. The bottom of the coating plate 35 is attached to the bottom of the liquid outlet tank 32. An arc-shaped groove is opened on the top of the coating plate 35. The top of the coating plate 35 is attached to the outer peripheral surface of the roller 30 at the arc-shaped groove. A drainage groove 36 is opened in the middle of the bottom of the coating plate 35.

[0049] It should be noted that both the first electric cylinder 26 and the second electric cylinder 33 are Hongfeng Transmission 60 model servo electric cylinders. The first electric cylinder 26 and the second electric cylinder 33 need to be connected to the same PLC controller, as well as the same servo controller used to drive the second electric cylinder 33. The servo controller is the SGDM-04ADA Yaskawa servo drive produced by Dongguan Mingfeng Automation Equipment Co., Ltd. The connection method of the second electric cylinder 33, the connecting wires and the control equipment is existing technology and mature, so the specific connection relationship will not be described in detail. It can be used by installing the existing connection assembly.

[0050] The PLC controller drives the second electric cylinder 33 to extend and retract via the servo controller, which in turn moves the top plate 34 and the coating plate 35 connected to it. The coating plate 35 can move at the bottom of the liquid outlet tank 32. At the same time, the coating material in the coating plate 35 rises and flows back to the liquid outlet tank 32 through the trough 36. At this time, a layer of coating material will be attached to the inner surface of the arc-shaped groove at the top of the coating plate 35. When the roller 30 continues to rotate, the coating material at the arc-shaped groove at the top of the coating plate 35 will be coated onto the outer circumferential surface of the roller 30, thus realizing the coating work on the roller 30 and preparing for subsequent rolling and other processes.

[0051] The implementation principle of the automatic roll material feeding mechanism in this application embodiment is as follows: First, the waterproof roll material to be fed is placed between the air expansion shaft 3 and the locking head 5. Then, after the roll material is opened, it passes between the first drive roller 7 and the second drive roller 15, and the bottom of the limiting roller 18. When the servo motor 6 is connected to the external power supply and is powered on, the waterproof roll material is driven by the first drive roller 7 to start feeding into the rectangular hole 1602 at one end of the support platform 16. At the same time, the two rotating columns 8 can drive the horizontal shaft 20 to start rotating under the action of the belt 9, thereby driving the roller 30 inserted into the mounting head 22 to start rotating. Then, the second electric cylinder 33 is started to unfold through the servo controller, so that the arc surface at the top of the coating plate 35 can coat the outer surface of the roller 30 with adhesive. When the waterproof roll material is fed down from the rectangular hole 1602, since the roller 30 is located vertically below the rectangular hole 1602, when the waterproof roll material comes into contact with the low-speed rotating roller 30, the adhesive on the surface of the roller 30 can wrap the roll material around the outer surface of the roller 30.

[0052] Once the roll reaches a certain length, the first electric cylinder 26 is activated via the servo controller. Simultaneously, the servo motor 6 is de-energized, and the first drive roller 7 and the drum 30 stop rotating. At this time, the bottom of the support platform 16 of the push plate 27 moves, thereby causing the blade 28 to insert into the cutting groove 1601, achieving transverse cutting of the waterproof roll. When the roll is cut, the ends of the roll are squeezed by the blade 28 and the cutting groove 1601. However, since the roll is in a vertical direction at this time, when the servo motor 6 is energized, the roll continues to be conveyed. After its ends come into contact with the outer surface of the drum 30 and are adhered, it will still be wound on the outer surface of the drum 30 and will not affect the subsequent winding of the roll.

[0053] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
