Description

Technical Field

[0001] The invention relates to the technical field of sheet material processing, in particular to an adjustable modular sheet material bottom film peeling structure. Background Art

[0002] As we all know, sheet base film peeling is the operation of separating the products or components adhered to the base film from the base film during the product manufacturing process. In the prior art, there are many methods including the operator directly tearing the sheet off the base film by hand, or using pulling and peeling, which are suitable for a variety of scenarios.

[0003] When processing sheets, the base film needs to be peeled off first. The existing technology has the following problems: in the mechanical peeling scenario, if there are irregular-shaped sheets or a large number of sheets to be peeled off continuously, it is difficult to quickly connect the sheet conveying for peeling operation. Especially for irregular-shaped sheets, not only is the peeling efficiency low, but there is also a risk of damaging the sheet. In order to overcome the possible strong adhesion between the base film and the sheet, the base film is sometimes heated before peeling to assist peeling. However, the sheet and the base film are retained in the heating environment for a long time, which not only reduces the efficiency, but also easily causes the base film to melt due to the long heating time or damages some sheets that are not resistant to high temperatures.

[0004] Based on the above-mentioned situation, we found that it is difficult for the existing bottom film peeling structure to avoid the above problems at the same time. Therefore, we proposed a method that can continuously peel off the sheets and can peel off special-shaped sheets. The bottom film can be directly collected during peeling. The modular design can also quickly replace or maintain the structure when peeling sheets of different specifications. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides an adjustable modular sheet base film peeling structure, which can continuously peel off sheets and can peel off special-shaped sheets. The base film can be directly collected during peeling. The modular design also has the advantage of quickly replacing or maintaining the structure when peeling sheets of different specifications.

[0007] (II) Technical solution

[0008] The above technical objectives of the present invention are achieved through the following technical solutions: an adjustable modular sheet base film peeling structure, comprising two conveyor frames, the inner side of which is provided with a synchronous belt through a transmission shaft and a synchronous pulley, the outer side of the left conveyor frame is fixedly connected to a limit frame, the bottom of the right side of the left conveyor frame is fixedly connected to an extension frame, and the top of the extension frame is fixedly connected to a peeling assembly;

[0009] The peeling assembly comprises a stand, the inner side of which is fixedly connected with a peeling shaft, a suspension is provided on the right side of the stand, and a film pushing assembly is provided on the inner side of the suspension;

[0010] The falling shaft comprises a hollow shaft and a silicone suction cup installed on the inner side of the hollow shaft, the inner side of the hollow shaft is rotatably connected with a sleeve shaft, the side of the sleeve shaft close to the stand is fixedly connected to the stand, a vacuum pump is installed on the inner side of the sleeve shaft, an air intake spacer and an exhaust spacer are fixedly connected to the outer side of the sleeve shaft, the outer sides of the air intake spacer and the exhaust spacer are both in contact with the inner wall of the hollow shaft, the air intake spacer and the exhaust spacer are both made of rubber material, the air intake end of the vacuum pump is fixedly connected with a suction pipe, the suction pipe is located on the inner side of the air intake spacer, the exhaust end of the vacuum pump is fixedly connected with a purge pipe, the purge pipe is arranged on the inner side of the exhaust spacer;

[0011] The film pushing assembly includes a sheet pressing mechanism and a roller frame, the sheet pressing mechanism is arranged on the top of the suspension, a branch sheet is fixedly connected to the right side of the roller frame, a picker is fixedly connected to the top of the branch sheet, the outer side of the roller frame is fixedly connected to the suspension, and a friction roller is rotatably connected to the inner side of the roller frame, and the friction roller is made of a rubber roller with a groove on the outer side.

[0012] The above technical solution is adopted, and a conveyor frame is provided to support the structure. The synchronous belt directly contacts the sheet material and conveys it so that it moves from left to right along the device. When the sheet material passes through the conveyor frame, it will first be limited by the limit frame to make its position relatively straight and not easy to deviate. The provided extension frame is used to install the peeling component. When the sheet material passes through the gap between the two conveyor frames, the peeling component peels off the bottom film of the sheet material. During the continuous operation of the peeling component, the sheet material passes through the top of the peeling shaft, and due to the peeling shaft The hollow shaft is always in a rotating state on the outside of the sleeve shaft, so the silicone suction cup installed on its inside will contact the bottom film at the bottom of the sheet when it moves to the top, and the vacuum pump on the inside of the shedding shaft generates vacuum suction, and the adsorption range of its suction tube is limited by the air intake spacer, so only the range inside the air intake spacer inside the hollow shaft will be negative pressure, and the silicone suction cup rotating to this area within the range will generate suction, so the silicone suction cup will be adsorbed on the surface of the bottom film. At the same time, the pressing mechanism of the film pushing assembly continues to press the top of the sheet to prevent it from warping, and its roller frame The inner friction roller will rub the right bonding edge of the sheet and the bottom film, causing a gap or deformation of the bottom film. The silicone suction cup that generates suction will continuously adsorb the bottom film and pull it downward to peel off the bottom film. Even if peeling does not occur, the pick-off knife on the right side of the branch piece will be stuck between the deformed bottom film on the right and the sheet to peel it off. The gas continuously discharged by the vacuum pump will blow the heated airflow to the bottom of the sheet obliquely above under the limitation of the purge pipe and the exhaust spacer to heat the bottom film and assist in its peeling. Since the sheet is in a state of continuous motion, it will not peel off. Overheating, and because the peeling position is close to the heating position, there is no need to worry about the ineffectiveness caused by too fast cooling. This design can separate the sheet and the bottom film by friction for different sheets, reducing the need for adjustment when peeling the bottom film for sheets of different thicknesses or shapes. The hollow shaft cooperates with the silicone suction cup to absorb the bottom film and pull it, which can not only cooperate with the friction roller to peel and peel, but also assist in the discharge and collection of the bottom film, and at the same time, it can also heat the peeled bottom film to assist in peeling.

[0014] By adopting the above technical solution, by setting an external frame in conjunction with a limiting guide rail, when the sheet material needs to be limited, the slider can be moved along the limiting guide rail, and the wheel frame and limiting wheel connected to the slider will be close to the front and rear sides of the sheet material, and will limit it when contacting the sheet material, so that it is relatively close to the center position of the moving trajectory.

[0020] By adopting the above technical solution, by setting up a suspension and a sliding rod, the electric cylinder can be extended or shortened according to the thickness of the sheet to adjust the horizontal height of the sliding rod, so that the pressure frame and the pressure roller cooperate with the top of the sheet to limit it, avoiding the pressure roller being too low and blocking the sheet from moving forward.

[0021] The present invention is further configured as follows: a pressure spring is fixedly connected to the top of the pressure frame, and the top of the pressure spring is fixedly connected to the top of the inner side of the suspension.

[0022] By adopting the above technical solution, a pressure spring is set up to make the pressure frame always receive downward force. When the sheet passes through and contacts the pressure frame, it needs to overcome the force of the deformation of the pressure spring to avoid the force applied by the weight of the pressure frame and the pressure roller being insufficient to limit the sheet.

[0023] The present invention is further configured as follows: a motor and a reducer are installed on the top of the extension frame, the output ends of the motor and the reducer are rotatably connected to the inner side of the vertical frame, the output ends of the motor and the reducer and the outer side of the hollow shaft are fixedly connected with a first pulley, and the two first pulleys are connected by a transmission belt.

The motor and the reducer can drive the auxiliary shaft to rotate through the second pulley and the transmission belt. At the same time, the friction roller connected to it through the gear will rotate in the opposite direction to the output direction of the motor under the transmission of the gear, so as to facilitate the peeling of the base film.

[0027] The present invention is further configured as follows: a shielding awning is provided on the outer side of the left conveying frame, a cylinder is fixedly connected to the inner side of the right conveying frame, and a belt conveyor is fixedly connected to the telescopic end of the cylinder.

[0031] (III) Beneficial effects

[0032] Compared with the prior art, the present invention provides an adjustable modular sheet base film peeling structure, which has the following beneficial effects:

[0033] The adjustable modular sheet bottom film peeling structure supports the structure by setting a conveyor frame. The synchronous belt directly contacts the sheet and conveys it to move it from left to right along the device. When the sheet passes through the conveyor frame, it will first be limited by the limit frame to make its position relatively straight and not easy to deviate. The set extension frame is used to install the peeling component. When the sheet passes through the gap between the two conveyor frames, the peeling component peels off the bottom film of the sheet. During the continuous operation of the peeling component, the sheet passes the top of the peeling shaft. Since the hollow shaft of the shedding shaft is always in a rotating state outside the sleeve shaft, the silicone suction cup installed inside it will contact the bottom film at the bottom of the sheet when it moves to the top, and the vacuum pump inside the shedding shaft generates vacuum suction, and the adsorption range of its suction tube is limited by the air intake spacer. Therefore, only the range inside the air intake spacer inside the hollow shaft will have negative pressure, and the silicone suction cup rotating to this area within the range will generate suction, so the silicone suction cup will be adsorbed on the surface of the bottom film. At the same time, the pressing mechanism of the film pushing assembly continuously presses the top of the sheet to prevent it from warping. The friction roller on the inner side of the roller frame will rub the right bonding edge of the sheet and the bottom film, causing a gap or deformation of the bottom film. The silicone suction cup that generates suction will continuously adsorb the bottom film and pull it downward to peel off the bottom film. Even if it does not peel off, the pick-off knife on the right side of the branch piece will be stuck between the deformed bottom film on the right and the sheet to peel it off. The gas continuously discharged by the vacuum pump will blow the heated airflow to the bottom of the sheet obliquely above under the limitation of the purge pipe and the exhaust spacer to heat the bottom film and assist in its peeling. Since the sheet is in a state of continuous motion, it will not Overheating will occur, and because the peeling position is close to the heating position, there is no need to worry about the ineffectiveness caused by cooling too quickly. This design can separate the sheet and the base film through friction for different sheets, reducing the need for adjustment when peeling the base film for sheets of different thicknesses or shapes. The hollow shaft cooperates with the silicone suction cup to absorb and pull the base film, which can not only cooperate with the friction roller to peel and peel, but also assist in the discharge and collection of the base film, and at the same time, it can also heat the peeled base film to assist in peeling.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1

[0046] See also Figure 1-8 , an adjustable modular sheet base film peeling structure, comprising two conveyor frames 1, a synchronous belt 2 is installed on the inner side of the conveyor frame 1 through a transmission shaft and a synchronous pulley, a limiting frame 3 is fixedly connected to the outer side of the left conveyor frame 1, an extension frame 4 is fixedly connected to the bottom of the right side of the left conveyor frame 1, and a peeling component 5 is fixedly connected to the top of the extension frame 4;

[0047] The structure is supported by setting up a conveyor frame 1, and the synchronous belt 2 is in direct contact with the sheet material and conveys it so that it moves from left to right along the device. When the sheet material passes through the conveyor frame 1, it will first be limited by the limit frame 3 to make its position relatively straight and not easy to shift. The extended frame 4 is used to install the peeling component 5. When the sheet material passes through the gap between the two conveyor frames 1, the peeling component 5 peels off the bottom film of the sheet material.

[0048] The limiting frame 3 includes an outer frame 31, the top of the outer frame 31 is fixedly connected to the limiting guide rail 32, the inner side of the limiting guide rail 32 is slidably connected to a slider 33, the bottom of the slider 33 is fixedly connected to a wheel frame 34, and the bottom of the wheel frame 34 is rotatably connected to a limiting wheel 35. By arranging the outer frame 31 to cooperate with the limiting guide rail 32, when it is necessary to limit the sheet material, the slider 33 can be moved along the limiting guide rail 32, and the wheel frame 34 and the limiting wheel 35 connected to the slider 33 will be close to the front and rear sides of the sheet material, and will limit the sheet material when it contacts the sheet material so that it is relatively close to the center position of the moving trajectory. The limiting guide rail 32 includes a sliding frame 321 and a bidirectional screw rod 322 rotatably connected to the inner side of the sliding frame 321. The bidirectional screw rod 322 The rear side of the slide frame 321 passes through and is equipped with a rotating handle. By setting a bidirectional screw rod 322 to cooperate with the slider 33, the bidirectional screw rod 322 can be directly rotated when the position between the sliders 33 needs to be adjusted. When the bidirectional screw rod 322 rotates, the slider 33 connected thereto will synchronously move horizontally along the limiting guide rail 32. A shielding canopy is provided on the outer side of the left conveyor frame 1, and a cylinder 14 is fixedly connected to the inner side of the right conveyor frame 1. The telescopic end of the cylinder 14 is fixedly connected to a belt conveyor 15. By setting a shielding canopy, the impurities that may be present in the external environment and affect the quality of the sheet material can be reduced. The cylinder 14 cooperates with the belt conveyor 15. When there are defective products or bottom films that cannot be peeled off in the sheet material, they can be lifted and conveyed out of the device for later processing.

[0049] Working principle of this embodiment: First, a synchronous belt 2 is installed on the inner side of the conveyor frame 1 through a transmission shaft and a synchronous pulley, a limit frame 3 is fixed on the outer side of the left conveyor frame 1, an extension frame 4 is connected to the bottom of the right side, and a peeling component 5 is installed on the top of the extension frame 4, a cylinder 14 is connected to the inner side of the right conveyor frame 1, and a belt conveyor 15 is connected to the telescopic end of the cylinder 14.

If there are defective products or bottom films that cannot be peeled off in the sheet, the cylinder 14 is actuated to lift it up through the belt conveyor 15 and convey it out of the device for subsequent processing.

[0050] Example 2

[0051] refer to Figure 1-9 An adjustable modular sheet base film peeling structure also includes a peeling assembly 5, wherein the peeling assembly 5 includes a stand 51, a peeling shaft 52 is fixedly connected to the inner side of the stand 51, a suspension 53 is provided on the right side of the stand 51, and a film pushing assembly 54 is provided on the inner side of the suspension 53;

[0052] The shedding shaft 52 includes a hollow shaft 521 and a silicone suction cup 522 installed on the inner side of the hollow shaft 521. The inner side of the hollow shaft 521 is rotatably connected with a sleeve shaft 523. The side of the sleeve shaft 523 close to the stand 51 is fixedly connected to the stand 51. A vacuum pump 524 is installed on the inner side of the sleeve shaft 523. An air intake spacer 525 and an exhaust spacer 526 are fixedly connected to the outer side of the sleeve shaft 523. The outer sides of the air intake spacer 525 and the exhaust spacer 526 are both in contact with the inner wall of the hollow shaft 521. The air intake spacer 525 and the exhaust spacer 526 are both made of rubber material. The air intake end of the vacuum pump 524 is fixedly connected with a suction pipe 527, and the suction pipe 527 is located on the inner side of the air intake spacer 525. The exhaust end of the vacuum pump 524 is fixedly connected with a purge pipe 528, and the purge pipe 528 is arranged on the inner side of the exhaust spacer 526.

[0053] The film pushing assembly 54 includes a sheet pressing mechanism 541 and a roller frame 542. The sheet pressing mechanism 541 is arranged on the top of the suspension frame 53. A branch sheet 543 is fixedly connected to the right side of the roller frame 542. A picker 544 is fixedly connected to the top of the branch sheet 543. The outer side of the roller frame 542 is fixedly connected to the suspension frame 53. A friction roller 545 is rotatably connected to the inner side of the roller frame 542. The friction roller 545 is made of a rubber roller with a groove on the outer side.

[0054] During the continuous operation of the peeling component 5, the sheet passes through the top of the shedding shaft 52. Since the hollow shaft 521 of the shedding shaft 52 is always in a rotating state on the outside of the sleeve shaft 523, the silicone suction cup 522 installed on the inside will contact the bottom film of the sheet when it moves to the top. The vacuum pump 524 on the inside of the shedding shaft 52 generates vacuum suction, and the adsorption range of the suction tube 527 is limited by the air intake spacer 525. Therefore, only the range inside the air intake spacer 525 inside the hollow shaft 521 will be negative pressure, and suction will be generated on the silicone suction cup 522 that rotates to this area within the range. Therefore, the silicone suction cup 522 will be adsorbed on the surface of the bottom film. At the same time, the pressing mechanism 541 of the film pushing component 54 continuously presses the top of the sheet to prevent it from warping. The friction roller 545 on the inner side of the roller frame 542 will rub the right side bonding edge of the sheet and the base film, causing a gap or deformation of the base film, and the silicone suction cup 522 that generates suction will continuously adsorb the base film and pull it downward to peel off the base film. Even if peeling does not occur, the pick knife 544 on the right side of the branch piece 543 will be stuck between the deformed base film on the right and the sheet to peel it off, and the gas continuously discharged by the vacuum pump 524 will blow the heated airflow to the bottom of the sheet obliquely above under the limitation of the purge pipe 528 and the exhaust spacer 526 to heat the base film and assist in its peeling. Since the sheet is in a state of continuous motion, it will not be overheated. At the same time, since the peeling position is close to the heating position, there is no need to worry about it cooling too quickly and causing it to have no effect.

[0055] The outer side of the sleeve shaft 523 is fixedly connected with a slip ring 6, and the outer side of the slip ring 6 is slidably connected to the inner side of the hollow shaft 521. A heating tube 7 is installed on the inner side of the exhaust spacer 526. By setting the slip ring 6, it is convenient to connect and support the sleeve shaft 523 and the hollow shaft 521, and at the same time, the hollow shaft 521 can be rotated along the slip ring 6. The heating tube 7 is used to heat the airflow discharged by the vacuum pump 524. The pressing mechanism 541 includes an electric cylinder 541a fixedly connected to the top of the suspension 53, and a sliding rod 541b is provided at the telescopic end of the electric cylinder 541a. The outer side of the sliding rod 541b is slidably connected to the suspension 53, and the bottom of the sliding rod 541b is fixedly connected to a pressing frame 541c, and the inner side of the pressing frame 541c is rotatably connected to a pressing roller 541d. The suspension 53 is set to cooperate with the slide bar 541b. According to the thickness of the sheet material, the electric cylinder 541a can be extended or shortened to adjust the horizontal height of the slide bar 541b, so that the pressure frame 541c and the pressure roller 541d cooperate with the top of the sheet material to limit it, to avoid the pressure roller 541d being too low and blocking the sheet material from moving forward. The top of the pressure frame 541c is fixedly connected with a pressure spring 8, and the top of the pressure spring 8 is fixedly connected to the top of the inner side of the suspension 53. By setting the pressure spring 8, the pressure frame 541c is always subject to a downward force. When the sheet material passes by and contacts the pressure frame 541c, it needs to overcome the deformation force of the pressure spring 8 to avoid the force applied by the weight of the pressure frame 541c and the pressure roller 541d being insufficient to limit the sheet material. A motor is installed on the top of the extension frame 4. The motor and the reducer 9 are connected to the inner side of the stand 51 for rotation. The output ends of the motor and the reducer 9 and the outer side of the hollow shaft 521 are fixedly connected with a first pulley 10. The two first pulleys 10 are connected by a transmission belt. The motor and the reducer 9 are arranged to drive part of the structure. The hollow shaft 521 can be driven to rotate along the outer side of the sleeve shaft 523 through the first pulley 10 and the transmission belt. The output shaft of the motor and the reducer 9 is in contact with the stand 51 to ensure its force strength. The inner side of the suspension 53 is connected to the auxiliary shaft 11 for rotation. The output ends of the motor and the reducer 9 and the outer side of the auxiliary shaft 11 are fixedly connected with a second pulley 12. The two second pulleys 12 are connected by a transmission belt. Gears 13 are installed on the outer sides of 11 and the friction roller 545, and the two gears 13 are meshed and connected. The auxiliary shaft 11 is set to assist the motor and the reducer 9 in transmission. The motor and the reducer 9 can drive the auxiliary shaft 11 to rotate through the second pulley 12 and the transmission belt. At the same time, the friction roller 545 connected thereto through the gear 13 will rotate in the opposite direction of the output direction of the motor under the transmission of the gear 13, so as to facilitate the peeling of the bottom film. A splicing groove 16 is fixedly connected to the inner side of the right conveying frame 1, and a pull-out frame 17 is slidably connected to the inner side of the splicing groove 16. An integrally formed arc piece is provided at the bottom of the left side of the suspension 53, and a guide piece 18 is fixedly connected to the right side of the inner side of the left conveying frame 1. The splicing groove 16 is provided to cooperate with the pull-out frame 17.After the bottom film is peeled off, it will slide down along the guide sheet 18 and the arc sheet, and finally fall into the inner side of the sheet slot 16. After periodic collection, the stacked bottom films can be taken out by pulling out the pull-out rack 17 for later processing.

[0056] Working principle of this embodiment: First, according to the thickness of the sheet material, operate the electric cylinder 541a on the top of the suspension 53 to adjust the horizontal height of the slide bar 541b so that the pressing frame 541c and the pressing roller 541d can properly limit the top of the sheet material to prevent the pressing roller 541d from being too low to block the sheet material from moving forward. Then turn on the heating tube 7 to prepare for the subsequent heating of the airflow discharged by the vacuum pump 524. During operation, turn on the motor and reducer 9 and the vacuum pump 524 to make the hollow shaft 521 start to rotate. When the silicone suction cup 522 rotates to the top with the hollow shaft 521, it adsorbs the bottom film of the sheet material under the suction force of the vacuum pump 524. Because the adsorption range of the suction tube 527 is limited by the air intake spacer 525, only the silicone suction cup 522 on the inner side of the air intake spacer 525 generates suction, and the pressing roller 541d of the sheet pressing mechanism 541 continues to press the top of the sheet material under the action of the pressure spring 8. To prevent the sheet from warping, the friction roller 545 rotates in the opposite direction under the transmission of the motor and the reducer 9 through the auxiliary shaft 11 and the gear 13, rubbing the right bonding edge of the sheet and the bottom film, causing a gap or deforming the bottom film, the silicone suction cup 522 adsorbs the bottom film and pulls it downward, and cooperates with the friction roller 545 to peel off the bottom film. If it is not peeled off, the picking knife 544 is stuck between the deformed bottom film on the right and the sheet to pick off the bottom film. The gas discharged by the vacuum pump 524 is heated by the heating tube 7, and under the limitation of the purge tube 528 and the exhaust spacer 526, the heated air flow is purged to the bottom of the obliquely upper sheet to assist in peeling off the bottom film and avoid excessive heating of the sheet. After the bottom film is peeled off, it slides down along the guide sheet 18 and the arc-shaped sheet at the bottom left of the suspension 53, and finally falls into the sheet splicing groove 16. The pull-out frame 17 is regularly pulled out to take out the superimposed bottom film for subsequent processing.
