Description

Background Technology

[0002] In the current sheet metal coiling field, traditional coiling equipment commonly suffers from problems such as uneven coiled edges and interlayer misalignment, easily leading to steel plate skirt defects and affecting finished product quality. Unstable tension control during coiling can cause coil collapse, resulting in poor coiling and forming effects that fail to meet the requirements of continuous production lines. Conventional coiling equipment lacks real-time edge detection and automatic follow-up adjustment functions; coiling alignment accuracy relies on manual adjustment, exhibiting significant lag and poor adaptability. Furthermore, traditional coiling equipment is mostly unidirectional coiling, which can easily lead to conveyor jamming and poor steering during reverse coiling. Deep foundation excavation is required, resulting in high construction costs, long construction periods, and significant maintenance and debugging difficulties. Summary of the Invention

[0019] The invention can be further understood through the specific embodiments given below, but they are not intended to limit the invention. Example 1

[0020] like Figures 1 to 16 As shown, this embodiment 1 provides a constant tension intelligent edge-aligning winding device, including a forward and reverse winding clamping mechanism 1, a winding mechanism 2, an auxiliary support mechanism 3, a constant tension mechanism 4, and a CCD detection mechanism 5. The winding mechanism 2 is arranged opposite to the winding mechanism 2, which winds up the conveyed sheet metal. The auxiliary support mechanism 3 is located on the side of the winding mechanism 2 to provide support for the winding operation. The constant tension mechanism 4 is located inside the section of the winding mechanism 2 where the sheet metal is wound. The CCD detection mechanism 5 is located at the front end on the side away from the winding mechanism 2 to detect the edge-aligning status of both sides of the sheet metal in real time.

[0021] like Figure 4 and Figure 5 As shown, the forward and reverse winding clamping mechanism 1 includes a mounting base 100, a side plate frame 101, an upper pressure silicone roller 102, a lower pressure silicone roller 103, a rotary receiving mechanism 104, and a variable frequency adjustable torque motor 106. The side plate frame 101 is fixed to both sides of the mounting base 100. The upper pressure silicone roller 102 is slidably mounted between the two side plate frames 101 and located above the lower pressure silicone roller 103. The lower pressure silicone roller 103 is fixedly mounted between the two side plate frames 101. The variable frequency adjustable torque motor 106 is driven by the upper pressure silicone roller 102 via a coupling 107. The rotary receiving mechanism 104 is connected to the lower pressure silicone roller 103. The upper pressure silicone roller 102 and the lower pressure silicone roller 103 cooperate to guide the material for forward and reverse winding, and smoothly transport the sheet material from the forward and reverse winding clamping mechanism 1 to the winding mechanism 2.

[0022] The upper pressure silicone roller 102 corresponds to the upper roller mechanism in the forward and reverse winding clamping and turning device, and the lower pressure silicone roller 103 corresponds to the lower roller mechanism. The side plate frame 101 is provided with a slider 201. The upper pressure silicone roller 102 is slidably connected to the slider 201 via an upper mounting seat. A pressure cylinder is provided at the top of the side plate frame 101. The pressure cylinder drives the upper mounting seat to move up and down along the slider 201 to adjust the gap between the upper pressure silicone roller 102 and the lower pressure silicone roller 103.

[0023] The rotary receiving mechanism 104 includes a rotary swing arm 1041, a guide assembly 1042, and a stroke cylinder 105. One end of the rotary swing arm 1041 is rotatably connected to the lower pressure silicone roller 103, and the other end is fixedly connected to the guide assembly 1042. The guide assembly 1042 includes an upper guide plate 10421 and a lower telescopic guide plate 10422. A telescopic guide plate cylinder 10423 is provided at the bottom of the lower telescopic guide plate 10422, and the stroke cylinder 105 is located at the bottom of the guide assembly 1042. Positioning sleeves are fitted on both sides of the connection between the rotary swing arm 1041 and the lower pressure silicone roller 103. The positioning sleeves clamp the rotary swing arm 1041 to prevent axial movement.

[0024] like Figure 1 and Figure 2 As shown, the CCD inspection mechanism 5 includes a mounting frame 500, a control board, a camera 501, and a light source. The camera 501 and the light source are mounted on the mounting frame 500, and the control board is integrated inside the square tubes on both sides of the mounting frame 500. The CCD inspection mechanism collects the edge position and width data of the board in real time, transmits the deviation signal to the control system, and drives the winding mechanism 2 to move left and right to ensure winding alignment.

[0025] like Figures 6 to 9 As shown, the winding mechanism 2 includes a base 200, a slider 201, a movable base 202, a DC motor 203, a gearbox 204, a winding drum 205, and a hydraulic cylinder 212. The slider 201 is mounted on the base 200, the movable base 202 is mounted on the slider 201, the gearbox 204 is fixed to the movable base 202, the output end of the DC motor 203 is connected to the gearbox 204 for transmission, one end of the winding drum 205 is rotatably connected to the gearbox 204, and the other end receives the sheet metal.

[0026] The hydraulic cylinder 212 is connected to the side end of the movable base 202 and drives the movable base 202 to move left and right along the length of the take-up drum 205 on the base 200 with the slider 201, so as to achieve the alignment of the plate edge. In actual use, the position of the plate edge is measured by the CCD detection mechanism 5 measurement system. The system directly drives the servo hydraulic cylinder 212 to push the movable base 202 to move left and right to ensure that the take-up edge is neat.

[0027] The gearbox 204 contains a gear assembly 206, which employs a two-stage transmission structure, including a first gear 2061, a second gear 2062, a third gear 2063, and a fourth gear 2064. The first gear 2061 and the second gear 2062 form the first-stage transmission pair, and the third gear 2063 and the fourth gear 2064 form the second-stage transmission pair. The first gear 2061 and the second gear 2062 mesh with each other, and the third gear 2063 and the fourth gear 2064 mesh with each other. The second gear 2062 and the third gear 2063 are coaxially fixed and rotate synchronously. The fourth gear 2064 is coaxially aligned with the take-up drum 205. Power is transmitted from the first-stage transmission pair to the second-stage transmission pair, and then output to the take-up drum 205 via the fourth gear 2064. All of the aforementioned gears are 11.5mm thick. The helical gear structure reduces transmission impact and reduces gear meshing clearance. The gearbox 204 uses gear oil immersion lubrication to ensure that all gear tooth surfaces are fully lubricated, achieving high torque, low noise, and zero clearance power output.

[0028] like Figure 10 and Figure 11 As shown, the constant tension mechanism 4 is located inside the take-up drum 205 and includes a spindle 400, a main shaft 401, and several blades 402. Specifically, there are four blades 402. The main shaft 401 is sleeved on the outer periphery of the spindle 400. One end of the main shaft 401 is connected to the gearbox 204 and is coaxial with the fourth gear 2064. The other end cooperates with the auxiliary support mechanism 3. The outer periphery of the main shaft 401 is covered by several blades 402. A bushing 403 is provided on the outer wall of the main shaft 401. Several wedge-shaped movable blocks 404 are provided between the main shaft 401 and the blades 402 along the length of the take-up drum 205. Oil filling holes 405 are opened on the outer wall of the blades 402, and the oil filling holes 405 extend through the wedge-shaped movable blocks 404 to the surface of the bushing 403.

[0029] The constant tension mechanism 4 of the present invention is driven by a DC motor 203 through a speed change mechanism. The system adjusts the output torque of the motor for each revolution by measuring the plate thickness (read by the front-end production line) and plate width (measured by the CCD detection mechanism 5) and calculating the results, so as to achieve a constant tension winding effect.

[0030] The winding mechanism 2 is equipped with a rotary cylinder 207. One end of the spindle 400 passes through the gearbox 204 and is connected to the output end of the rotary cylinder 207. The rotary cylinder 207 drives the spindle 400 and the main shaft 401 to rotate. Lubricating oil enters the lubrication part through the oil filling hole 405 to ensure the lubrication effect. The design of the oil filling hole 405 means that as long as the rotary cylinder 207 moves back and forth when adding lubricating oil, the parts that need lubrication of each layer can be lubricated, thereby simplifying the lubrication work and ensuring the lubrication effect.

[0031] The constant tension mechanism 4 of this invention is a hydraulic expansion shaft structure design, which can ensure that the main shaft 401 does not deform under force and rotates smoothly. The spindle 400 is driven by the rotary cylinder 207, which moves back and forth with the movable bushing 403. When the wedge-shaped movable block 404 installed on the movable bushing 403 moves back and forth, its unique inclined cooperation causes the four leaf plates 402 to produce an axial expansion and contraction action, thereby realizing the cooperation of the paper tube or iron tube to ensure that the paper tube and other media will not rotate during winding.

[0032] like Figure 1 and Figure 3 As shown, the auxiliary support mechanism 3 includes a support base 300 and a support platform 301. The support platform 301 is mounted on the support base 300. The end of the main shaft 401 away from the gearbox 204 is connected to the support sleeve 302. The support platform 301 and the support sleeve 302 are adapted to abut against each other to share the axial force of the main shaft 401, prevent deformation, and ensure smooth rotation.

[0033] The winding mechanism 2 is also equipped with a pressure roller mechanism, which is installed on the gearbox 204. The pressure roller mechanism includes a connecting seat 208, a pressure rod 209, a drive cylinder 210, and a pressing assembly 211. The connecting seat 208 is fixed to the gearbox 204. One end of the pressure rod 209 is fixed to the connecting seat 208, and the other end is rotatably connected to the pressing assembly 211. The pressing assembly 211 includes a connecting rod 2111 and a pressure roller 2112. The pressure roller 2112 cooperates with the winding drum 205. The drive cylinder 210 drives the pressure rod 209 to rotate, so that the pressure roller 2112 and the winding drum 205 are tightly fitted together, ensuring stable winding of the sheet material. Example 2

[0034] The difference between Example 2 and Example 1 is that the forward winding operation is performed.

[0035] like Figure 12 and Figure 13 As shown, a pressure cylinder drives the upper pressure silicone roller 102 downwards, creating a clamping gap between the upper pressure silicone roller 102 and the lower pressure silicone roller 103 that is adapted to the thickness of the sheet material. A variable frequency adjustable torque motor 106 drives the upper pressure silicone roller 102 to rotate. After being guided by the upper pressure silicone roller 102, the sheet material enters the upper guide plate 10421 of the rotary receiving mechanism 104, and then enters the winding drum 205 along the upper guide plate 10421 to complete the forward winding. The stroke cylinder 105 drives the rotary swing arm 1041 to maintain the forward winding posture, while the lower telescopic guide plate 10422 is in a retracted state, ensuring a smooth sheet material conveying path. Example 3

[0036] The difference between Example 3 and Example 1 is that the reverse winding operation is performed.

[0037] like Figure 14 and Figure 15As shown, the pressure cylinder drives the upper pressure silicone roller 102 to move upward, increasing the gap between the rollers. The stroke cylinder 105 drives the rotating swing arm 1041 to swing around the lower pressure silicone roller 103 to the reverse take-up position. The telescopic guide plate cylinder 10423 drives the lower telescopic guide plate 10422 to extend. After being guided by the lower pressure silicone roller 103, the sheet enters the take-up drum 205 along the lower telescopic guide plate 10422 to complete the reverse take-up. The sheet is conveyed without jamming or wrinkles.

[0038] The working principle of the constant tension intelligent edge-aligning winding device of the present invention is as follows: During operation, the CCD detection mechanism 5 monitors the edge position and width of the sheet material in real time, transmitting the data to the control system. The control system calculates the deviation value and drives the DC motor 203 to move the movable base 202 left and right, enabling the winding drum 205 to follow the edge of the sheet material, ensuring a neat winding edge. The constant tension mechanism 4 adjusts the motor output torque based on the sheet material thickness and width data to maintain constant winding tension. The rotary cylinder 207 drives the spindle 400 to move, causing the wedge-shaped movable block 404 to move, thus expanding or contracting the leaf plate 402. It is suitable for paper tube or iron tube installation, and the oil filling hole 405 simplifies lubrication operations. The pressure roller 2112 mechanism maintains a tight fit between the pressure roller 2112 and the winding drum 205 during winding, improving winding stability. It can quickly switch between forward and reverse winding modes, without the need for deep foundation digging, and is suitable for the thin sheet winding needs of multiple production lines such as embossing lines, rolling lines, color-printed sheets, pre-coated sheets, and laminated sheets.

[0039] The above description is merely an embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
