Description

Technical Field

[0001] This invention relates to the field of winding technology, specifically to an integrated machine for winding and packaging PC sheets with a core. Background Technology

[0002] PC sheets are widely used in construction, transportation, medical, electronics, and home furnishing fields, and have broad application prospects. The PC sheet winding device is an important station in the PC sheet production and processing process. The wound PC sheets are easier to store, transport and process. However, the existing PC sheet winding and packaging devices have many defects and cannot meet the usage requirements.

[0003] Before winding, PC sheets need to be trimmed, but burrs are easily generated during the trimming process. In a continuously running winding machine, it is difficult to accurately fix the PC sheets. PC sheets that are not accurately fixed are prone to skewing during the trimming process, which affects the quality of the output sheets. On the other hand, the continuous motion is not conducive to the removal of trimming burrs.

[0004] Conventional PC sheet winding devices require manual roll changing during operation, which greatly reduces the working efficiency of the winding device. Although some equipment has undergone some automation improvements, the connection between the core and the PC sheet still requires manual assistance during the roll changing process, making it impossible to achieve full automation of the entire winding, roll changing, and packaging process. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated machine for winding and packaging PC sheets with a core, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a PC sheet winding and packaging integrated machine with a core, comprising an edge trimming component, a winding component, a roll changing component, and a packaging component. The edge trimming component, winding component, and packaging component are fixedly connected to the ground. The edge trimming component is located on one side of the winding component, and the roll changing component is located on the upper side of the winding component and the packaging component. The roll changing component is connected to the winding component. The winding component includes a base support, a swing arm, an adjusting cylinder, a tension roller, and a power unit. The base support is fixedly connected to the ground. One end of the swing arm is rotatably connected to the base support, and the other end of the swing arm is rotatably connected to the output shaft of the adjusting cylinder. The adjusting cylinder is rotatably connected to the base support. The tension roller is rotatably connected to the end of the swing arm away from the base support. The power unit is connected to the base support. The edge trimming component trims the PC sheet, and the trimmed PC sheet is wound by the winding component. The roll changing component replaces the core, and the packaging component packages the replaced core. The cleaning unit of this invention first uses the enhanced blocking effect of burrs to trap metal powder, marks the burr position with the metal powder, and then guides the shot peening position through charge guidance, so that more shot peening can be concentrated on the burr position. This setting improves the burr removal efficiency on the one hand, and reduces the damage to PC sheet during the shot peening process on the other hand, greatly improving the overall cleaning effect.

[0007] Furthermore, the trimming assembly includes an input roller group, an output roller group, a cutting unit, a cleaning unit, and a setting plate. The setting plate is securely connected to the ground. The input roller group and the output roller group are respectively securely connected to both sides of the setting plate. The cutting unit and the cleaning unit are securely connected to the setting plate. The cutting unit and the cleaning unit are positioned between the input roller group and the output roller group, with the cutting unit closer to the input roller group and the cleaning unit closer to the output roller group. The PC sheet passes between the input roller group and the output roller group. The cutting unit cuts off both sides of the PC sheet, and the cleaning unit removes the burrs from both sides of the cut PC sheet.

[0008] Furthermore, the cutting unit includes a cutting cover, a lifting plate, a fixing unit, a cutting blade, and a lifting cylinder. The cutting cover is securely connected to the ground, the lifting plate is slidably connected to the cutting cover, the lifting cylinder is securely connected to the cutting cover, the output shaft of the lifting cylinder is securely connected to the lifting plate, and the cutting blade is securely connected to the lifting plate. Two sets of cutting blades are provided, one set positioned on each side of the lifting plate. Two rows of fixing units are provided; one row is securely connected to the lifting plate, and the other row is securely connected to the bottom of the cutting cover. The two rows of fixing units are arranged opposite each other, with four sets in each row. The fixing units securely connected to the lifting plate are located on both sides of the cutting blade. The lifting cylinder can move the lifting plate to adjust the height of the fixing units and the cutting blade. Initially, the upper and lower fixing units are separated. When the PC sheet is input into the fixing unit, the lifting cylinder moves the cutting blade downwards to cut the PC sheet, while the fixing unit continuously outputs the PC sheet.

[0009] Furthermore, the fixing unit includes an extension frame, an annular rolling belt, a cover, a fixed suction cup, a negative pressure pipe, and a lifting plate. The extension frame and lifting plate are fixedly connected in the fixing unit, and the cutting cover is also fixedly connected in the fixing unit. The annular rolling belt is mounted on the extension frame, and the cover is positioned inside the annular rolling belt. One end of the cover is close to the inner surface of the annular rolling belt. A dynamic seal is provided at the point where the cover and the annular rolling belt are close together. A fixed suction cup is located on the surface of the annular rolling belt, and the negative pressure pipe is connected to the cover. During the movement of the PC sheet, the annular rolling belt passes the cover. The negative pressure pipe draws airflow from inside the cover, keeping the inside of the cover under negative pressure. When the annular rolling belt passes the cover, the fixed suction cup, under negative pressure, adheres tightly to the surface of the PC sheet. When the annular rolling belt leaves the cover area, the air pressure of the fixed suction cup returns to normal, releasing its grip on the PC sheet, which then continues to move to the next workstation. In this invention, the fixing unit and the PC sheet move continuously, and during this continuous movement, the fixing suction cup undergoes a change in its adsorption state. The fixing suction cup and the PC sheet move synchronously, avoiding lateral tension caused by relative displacement. When the PC sheet passes the cutting blade position, both sides of the sheet are fixed by the annular rolling belt, providing a stable operating environment for the cutting blade. This fixing process continuously changes the position of the annular rolling belt as it rotates, enabling continuous fixed-point fixing even as PC sheets are continuously output.

[0010] Furthermore, the cleaning unit includes a cleaning hood, a marking chamber, and an impact chamber. The cleaning hood is securely connected to the ground. The marking chamber and impact chamber are located inside the cleaning hood and are securely connected to the cleaning hood. The marking chamber has a rotating cavity inside, with an arc-shaped inner side. An air inlet block and an air extraction block are located outside the rotating cavity. The air inlet block is connected to an external air supply pipe, and the air extraction block is connected to an external air extraction pipe. The air extraction speed of the external air extraction pipe is greater than the air supply speed of the external air supply pipe. The impact chamber has a recovery tank inside, with a shot peening port inside. Recovery ports are located on both sides of the recovery tank and are connected to an external suction pipe. The impact chamber has a shot peening device inside, which is connected to the shot peening port. The PC sheet sequentially passes through a marking chamber and an impact chamber. In the marking chamber, the PC sheet is inserted into a rotating cavity. Airflow is output from the air inlet block and recovered from the air extraction block. In this invention, positively charged metal powder is mixed inside the external air supply pipe to mark burrs. The positively charged metal powder flows in a U-shape with the airflow inside the rotating cavity. When the metal powder passes the trimming surface, it passes through the burr portion. The burr surface has a greater blocking effect than the flat surface of the PC sheet, so some of the positively charged metal powder is intercepted by the burr, and the rest is recovered by the air extraction block. The PC sheet continues to enter the impact chamber, where the shot inside the shot peening device is negatively charged and ejected from the shot peening nozzle, which is set to face the trimming surface. After the shot is ejected towards the trimming surface, it is collected from both sides by the recovery port. The cleaning unit of this invention first uses the enhanced blocking effect of burrs to trap metal powder, marks the burr position with the metal powder, and then guides the shot peening position through charge guidance, so that more shot peening can be concentrated on the burr position. This setting improves the burr removal efficiency on the one hand, and reduces the damage to PC sheet during the shot peening process on the other hand, greatly improving the overall cleaning effect.

[0011] Furthermore, the power unit includes a geared motor, an automatic gripper, a first electric cylinder, a second electric cylinder, an electrically controlled telescopic rod, and an adsorption plate. The geared motor and the base bracket are securely connected. The automatic gripper and the output shaft of the geared motor are securely connected. The first electric cylinder, the second electric cylinder, and the base bracket are securely connected. The output shaft of the first electric cylinder and the electrically controlled telescopic rod are securely connected. The output shaft of the second electric cylinder and the adsorption plate are securely connected. The electrically controlled telescopic rod, the adsorption plate, and the base bracket are slidably connected. A glue-applying block is provided at the end of the electrically controlled telescopic rod away from the base bracket. A lifting knife is provided in the middle of the adsorption plate, and adsorption discs are provided on both sides of the adsorption plate. The electrically controlled telescopic rod and the adsorption plate are located on the side of the automatic gripper near the tension roller. The automatic gripper clamps the core, and the geared motor drives the automatic gripper to rotate, which in turn drives the core to rotate. When a roll change is required, the second electric cylinder drives the adsorption plate to move upward, adsorbing the bottom side of the sheet material. The electrically controlled telescopic rod extends to cover the top of the sheet material, and the first electric cylinder drives the electrically controlled telescopic rod to move downward. The glue-applying block applies glue to both sides of the sheet material. The glue-applying block is a conventional technical means in this field, and its specific structure is not described. A lifting blade cuts the sheet metal, and an adsorption plate holds the sheet metal against the winding core. The cut side of the sheet metal is then fixed and output. A new winding core moves down and contacts the top of the sheet metal, adhering it to the new core. An automatic gripper then secures the new core, and winding continues. The power unit of this invention, through the coordinated operation of the adsorption plate and the electrically controlled telescopic rod, achieves automatic fixing of the cut sheet metal, greatly improving the stability of winding core replacement.

[0012] Furthermore, the roll changing assembly includes a crossbeam platform, a first module, a vertical plate, a second module, a clamping robotic claw, and a feeding belt. The crossbeam platform is securely connected to the ground, the first module is securely connected to the crossbeam platform, the vertical plate is securely connected to the displacement platform of the first module, the second module is securely connected to the vertical plate, the clamping robotic claw is securely connected to the displacement platform of the second module, and the feeding belt is securely connected to the ground. The feeding belt is located on one side of the packaging assembly. The first module drives the second module to move horizontally, and the second module drives the clamping robotic claw to move vertically. The clamping robotic claw first clamps and moves the fully loaded roll core to the unloading belt and then moves the new roll core from the feeding belt to the automatic gripper. The clamping robotic claw is a conventional technical means in this field, and its specific structure will not be described.

[0013] Furthermore, the packaging assembly includes a feeding belt and an automatic packaging machine. The feeding belt, the automatic packaging machine, and the ground are securely connected. The feeding belt is positioned closer to the roll changing assembly, and the automatic packaging machine is positioned on the side of the feeding belt away from the roll changing assembly. The feeding belt transports the wound core to the automatic packaging machine, which packages the core. The automatic packaging machine is a conventional technology in this field, and its specific structure will not be described.

[0014] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: The fixing unit and the PC sheet move continuously, and during this continuous movement, the fixing suction cup undergoes changes in its adsorption state. The fixing suction cup and the PC sheet move synchronously, avoiding lateral tension caused by relative displacement. When the PC sheet passes the cutting blade position, both sides of the sheet are fixed by annular rolling belts, providing a stable operating environment for the cutting blade. This fixing process continuously changes the position of the annular rolling belt as it rotates, enabling continuous fixed-point fixing even with continuous output of PC sheets. The cleaning unit of this invention first utilizes the enhanced blocking effect of burrs to trap metal powder, marking the burr positions with the metal powder. Then, it guides the shot peening position through charge guidance, allowing more shot peening to concentrate on the burr positions. This design improves burr removal efficiency and reduces damage to the PC sheet during shot peening, greatly enhancing the overall cleaning effect. The power unit of this invention, through the upper and lower cooperation of the adsorption plate and the electrically controlled telescopic rod, achieves automatic fixing of the sheet after cutting, greatly improving the stability of core replacement.

[0027] like Figure 1As shown, a PC sheet winding and packaging integrated machine with a core includes an edge trimming assembly 1, a winding assembly 2, a roll changing assembly 3, and a packing assembly 4. The edge trimming assembly 1, winding assembly 2, and packing assembly 4 are fixedly connected to the ground. The edge trimming assembly 1 is located on one side of the winding assembly 2, and the packing assembly 4 is located on the side of the winding assembly 2 away from the edge trimming assembly 1. The roll changing assembly 3 is located on the upper side of the winding assembly 2 and the packing assembly 4. The winding assembly 2 includes a base support 21, a swing arm 22, an adjusting cylinder 23, a tension roller 24, and a power unit 25. The base support 21 is fixedly connected to the ground. One end of the swing arm 22 is rotatably connected to the base support 21, and the other end of the swing arm 22 is rotatably connected to the output shaft of the adjusting cylinder 23. The adjusting cylinder 23 is rotatably connected to the base support 21. The tension roller 24 is rotatably connected to the end of the swing arm 22 away from the base support 21. The power unit 25 is connected to the base support 21. The trimming assembly 1 trims the edges of the PC sheet, and the trimmed PC sheet is then wound up by the winding assembly 2. The changing assembly 3 replaces the core roll, and the packaging assembly 4 packages the replaced core roll. The cleaning unit 14 of this invention first utilizes the enhanced blocking effect of burrs to trap metal powder, marking the burr locations with the metal powder, and then guiding the shot peening position through charge guidance, allowing more shot peening to concentrate on the burr locations. This design improves burr removal efficiency and reduces damage to the PC sheet during shot peening, greatly enhancing the overall cleaning effect.

[0028] like Figure 1 As shown, the trimming assembly 1 includes an input roller group 11, an output roller group 12, a cutting unit 13, a cleaning unit 14, and a setting plate 15. The setting plate 15 is securely connected to the ground. The input roller group 11 and the output roller group 12 are respectively securely connected to both sides of the setting plate 15. The cutting unit 13 and the cleaning unit 14 are securely connected to the setting plate 15. The cutting unit 13 and the cleaning unit 14 are located between the input roller group 11 and the output roller group 12, with the cutting unit 13 close to the input roller group 11 and the cleaning unit 14 close to the output roller group 12. The PC sheet passes between the input roller group 11 and the output roller group 12. The cutting unit 13 cuts off both sides of the PC sheet, and the cleaning unit 14 removes the burrs from both sides of the cut PC sheet.

[0029] like Figure 2 , Figure 3As shown, the excision unit 13 includes an excision cover 131, a lifting plate 132, a fixing unit 133, a cutting blade 134, and a lifting cylinder 135. The excision cover 131 is fixedly connected to the ground, the lifting plate 132 is slidably connected to the excision cover 131, the lifting cylinder 135 is fixedly connected to the excision cover 131, the output shaft of the lifting cylinder 135 is fixedly connected to the lifting plate 132, the cutting blade 134 is fixedly connected to the lifting plate 132, and there are two sets of cutting blades 134, which are respectively located on both sides of the lifting plate 132. There are two rows of fixing units 133, one row of which is fixedly connected to the lifting plate 132, and the other row of which is fixedly connected to the bottom of the excision cover 131. The two rows of fixing units 133 are arranged opposite to each other, and each row of fixing units 133 has four sets. The fixing units 133 that are fixedly connected to the lifting plate 132 are located on both sides of the cutting blade 134. The lifting cylinder 135 can move the lifting plate 132 to adjust the height of the fixed unit 133 and the cutting blade 134. In the initial state, the upper and lower fixed units 133 are separated. When the PC board is input into the fixed unit 133, the lifting cylinder 135 drives the cutting blade 134 to move down to cut the PC board, and the fixed unit 133 continuously outputs the PC board.

[0030] like Figure 4As shown, the fixing unit 133 includes an extension frame 1331, an annular rolling belt 1332, a cover 1333, a fixed suction cup 1334, a negative pressure pipe 1335, and a lifting plate 132. The extension frame 1331 and the lifting plate 132 in the fixing unit 133 are fixedly connected, and the cutting cover 131 in the fixing unit 133 are also fixedly connected. The annular rolling belt 1332 is disposed on the extension frame 1331, and the cover 1333 is disposed inside the annular rolling belt 1332. One end of the cover 1333 is close to the inner side of the surface of the annular rolling belt 1332. A dynamic seal is provided at the position where the cover 1333 and the surface of the annular rolling belt 1332 are close together. A fixed suction cup 1334 is provided on the surface of the annular rolling belt 1332. The negative pressure pipe 1335 is connected to the cover 1333. During the movement of the PC sheet, the annular rolling belt 1332 passes the cover 1333. The negative pressure pipe 1335 draws airflow from inside the cover 1333, keeping the inside of the cover 1333 under constant negative pressure. When the annular rolling belt 1332 passes the cover 1333, the fixed suction cup 1334 adheres to the surface of the PC sheet under negative pressure. When the annular rolling belt 1332 leaves the cover 1333, the air pressure of the fixed suction cup 1334 returns to normal, releasing its grip on the PC sheet, which then continues to move to the next workstation. The fixing unit 133 and the PC sheet move continuously, and during this continuous movement, the fixed suction cup 1334 undergoes changes in its adsorption state. The fixed suction cup 1334 and the PC sheet move synchronously, preventing lateral tension caused by relative displacement. When the PC sheet passes the cutting blade position, both sides of the sheet are fixed by the annular rolling belt, which provides a stable operating environment for the cutting blade. This fixing process changes the position of the annular rolling belt as it rotates, so that the fixed-point fixing can continue even when the PC sheet is continuously output.

[0031] like Figure 5 , Figure 6 , Figure 7As shown, the cleaning unit 14 includes a cleaning cover 141, a marking chamber 142, and an impact chamber 143. The cleaning cover 141 is fixedly connected to the ground. The marking chamber 142 and the impact chamber 143 are located inside the cleaning cover 141 and are fixedly connected to the cleaning cover 141. The marking chamber 142 has a rotating cavity 144 inside. The inner side of the rotating cavity 144 is set as an arc surface. The outer side of the rotating cavity 144 has an air inlet block 145 and an air extraction block 146. The air inlet block 145 is connected to an external air supply pipe, and the air extraction block 146 is connected to an external air extraction pipe. The air extraction speed of the external air extraction pipe is greater than the air supply speed of the external air supply pipe. The impact chamber 143 has a recovery tank inside. The recovery tank has a shot peening port 147 inside. The recovery ports 148 are set on both sides of the recovery tank and are connected to an external suction pipe. The impact chamber 143 has a shot peening device inside. The shot peening device is connected to the shot peening port 147. PC sheets sequentially pass through marking chamber 142 and impact chamber 143. At marking chamber 142, the PC sheet is inserted into rotary chamber 144. Airflow is output from air inlet block 145 and recovered from exhaust block 146. In this invention, positively charged metal powder is mixed inside the external air supply pipe to mark burrs. The positively charged metal powder flows in a U-shape within the rotary chamber with the airflow. When the metal powder passes the trimming surface, it passes the burr portion. The burr surface has a greater blocking effect than the flat surface of the PC sheet, so some of the positively charged metal powder is intercepted by the burr, while the rest is recovered by the exhaust block. The PC sheet continues into the impact chamber, where the shot peening gun is negatively charged and ejected from the shot peening nozzle, which is set to face the trimming surface. After being ejected towards the trimming surface, the shot is collected from both sides by the recovery port. The cleaning unit 14 of the present invention first uses the enhanced blocking effect of burrs to intercept metal powder, marks the burr position with metal powder, and then guides the shot peening position with charge guidance, so that more shot peening can be concentrated on the burr position. This setting improves the burr removal efficiency on the one hand, and reduces the damage to PC board during the shot peening process on the other hand, greatly improving the overall cleaning effect.

[0032] like Figure 1 , Figure 9As shown, the power unit 25 includes a geared motor 251, an automatic gripper 252, a first electric cylinder 253, a second electric cylinder 254, an electrically controlled telescopic rod 255, and an adsorption plate 256.

The electrically controlled telescopic rod 255 and the adsorption plate 256 are positioned on the side of the automatic gripper 252 near the tension roller 24. The automatic gripper 252 clamps the core, and the geared motor drives the automatic gripper 252 to rotate, which in turn drives the core to rotate. When a roll change is needed, the second electric cylinder 254 moves the adsorption plate 256 upward to adsorb the bottom side of the sheet material. The electrically controlled telescopic rod 255 extends to cover the top of the sheet material, and the first electric cylinder 253 moves the electrically controlled telescopic rod downward. Adhesive blocks apply adhesive to both sides of the sheet material. The adhesive blocks are a conventional technique in this field, and their specific structure is not described. The lifting knife cuts the sheet material, and the adsorption plate 256 presses the sheet material against the core. The cut side of the sheet material is fixed and output. The new core moves downward and contacts the top side of the sheet material, adhering the sheet material to the new core. The automatic gripper 252 fixes the new core, and winding continues. The power unit of this invention achieves automatic fixing of the cut sheet material through the upper and lower cooperation of the adsorption plate 256 and the electrically controlled telescopic rod 255, which greatly improves the stability of core replacement.

[0033] like Figure 1 As shown, the roll changing assembly 3 includes a crossbeam platform 31, a first module 32, a vertical plate 33, a second module 34, a clamping mechanical claw 35, and a feeding belt 36. The crossbeam platform 31 is fixedly connected to the ground, the first module 32 is fixedly connected to the crossbeam platform 31, the vertical plate 33 is fixedly connected to the displacement platform of the first module 32, the second module 34 is fixedly connected to the vertical plate 33, the clamping mechanical claw 35 is fixedly connected to the displacement platform of the second module 34, and the feeding belt 36 is fixedly connected to the ground. The feeding belt 36 is located on one side of the packaging assembly 4. The first module 32 drives the second module 34 to move horizontally, and the second module 34 drives the clamping mechanical claw 35 to rise and fall. The clamping mechanical claw 35 first clamps the fully rolled core and moves it to the unloading belt 41 to put it down, and then moves the new core from the feeding belt 36 to the automatic gripper 252. The clamping mechanical claw 35 is a conventional technical means in this field, and its specific structure is not described.

[0034] like Figure 1As shown, the packaging assembly 4 includes a feeding belt 41 and an automatic packaging machine 42. The feeding belt 41 and the automatic packaging machine 42 are securely connected to the ground. The feeding belt 41 is located on the side closer to the roll changing assembly 3, and the automatic packaging machine 42 is located on the side of the feeding belt 41 away from the roll changing assembly 3. The feeding belt 41 conveys the wound core to the automatic packaging machine 42, which packages the core. The automatic packaging machine 42 is a conventional technology in this field, and its specific structure will not be described.

[0035] The working principle of this invention is as follows: PC sheets pass between the input roller group 11 and the output roller group 12. Initially, the upper and lower fixing units 133 are separated. When the PC sheet is input into the fixing unit 133, the lifting cylinder 135 drives the cutting blade 134 to move downward to cut the PC sheet. The fixing unit 133 continuously outputs the PC sheet. When the annular rolling belt 1332 passes the cover 1333, the fixing suction cup 1334 will adhere to the surface of the PC sheet under negative pressure. When the annular rolling belt 1332 leaves the range of the cover 1333, the air pressure of the fixing suction cup 1334 returns to normal, and it will release the adsorption on the PC sheet, allowing the PC sheet to continue moving to the subsequent workstation. PC sheets sequentially pass through marking chamber 142 and impact chamber 143. At marking chamber 142, the PC sheet is inserted into rotary chamber 144. Airflow is output from air inlet block 145 and recovered from exhaust block 146. In this invention, positively charged metal powder is mixed inside the external air supply pipe to mark burrs. The positively charged metal powder flows in a U-shape within the rotary chamber with the airflow. When the metal powder passes the trimming surface, it passes the burr portion. The burr surface has a greater blocking effect than the flat surface of the PC sheet, so some of the positively charged metal powder is intercepted by the burr, while the rest is recovered by the exhaust block. The PC sheet continues into the impact chamber, where the shot peening gun is negatively charged and ejected from the shot peening nozzle, which is set to face the trimming surface. After being ejected towards the trimming surface, the shot is collected from both sides by the recovery port.
