Description

Technical Field

[0002] Aluminum foil slitting equipment is a key equipment used in the industrial field to cut wide aluminum foil coils into narrow coils or sheets of specific widths. The existing portable aluminum foil slitting equipment has a disc-type slitting knife driven by a motor, which directly cuts the aluminum foil by rotating the slitting knife. However, when the slitting knife rotates and contacts the aluminum foil, the slitting knife will generate static electricity due to friction, and the aluminum foil will produce aluminum foil powder and debris during the cutting process. The static electricity on the slitting knife will absorb the aluminum foil powder and debris, and make the residual material generated during the aluminum foil slitting process adhere to the slitting knife, resulting in a decrease in the smoothness of the slitting knife surface, which affects the slitting efficiency and the slitting quality of the aluminum foil.

Move and limit the slitting knife through two blocking frames. If the slitting knife shakes and an aluminum foil roll has not been slit, the slitting knife can be used temporarily as an emergency measure to reduce the probability of damage and shaking of the slitting knife, thereby ensuring the quality of the aluminum foil after slitting; 4. By limiting and straightening the two points of the slitting knife, the probability of the slitting knife bending and deforming due to excessive shaking and being limited by a single point is reduced, thereby reducing the probability of the aluminum foil being damaged by the deformed slitting knife, thereby ensuring the quality of the aluminum foil cut by the slitting knife; 5. The slitting knife is blocked by a protective net.

DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] A portable slitting device for aluminum foil processing, such as Figure 1-Figure 5 As shown, it includes: an electric slide 1. When using the device, several devices distributed in a straight line are installed on a fixed roller (so that the electric slide 1 can slide on the fixed roller). The electric slide 1 is provided with a control terminal not shown in the figure. The electric slide 1 is provided with a motor 2. The electric slide 1 and the motor 2 are both electrically connected to the control terminal. The output shaft of the motor 2 is fixedly connected with a slitting knife 3. The electric slide 1 is fixedly connected with a protective shell 4 for shielding the upper part of the slitting knife 3; a fixed plate 5 is fixed in the protective shell 4. The fixed plate 5 is slidably connected with two extrusion plates 6 symmetrically distributed on the left and right and two blocking frames 7 symmetrically distributed on the left and right. The material of the blocking frame 7 can be the same as that of the brake pad (for example, a resin-based material or a semi-metallic material). The protective shell 4 is provided with channels symmetrically distributed on the left and right. The extrusion plate 6 and the adjacent blocking frame 7 slide in the adjacent channels on the protective shell 4. The extrusion plate 6 is slidably connected to the adjacent blocking frame 7. A first elastic member is fixedly connected between the extrusion plate 6 and the adjacent blocking frame 7, wherein the space between the extrusion plate 6 and the adjacent blocking frame 7 is The first elastic member is a compression spring. The blocking frame 7 is located between the adjacent extrusion plate 6 and the slitting knife 3. There is a gap between the blocking frame 7 and the slitting knife 3. Under the premise that the blocking frame 7 does not rub the surface of the slitting knife 3, the blocking frame 7 blocks the aluminum foil waste adhering to the slitting knife 3. The slitting knife 3 is located between the symmetrically distributed blocking frames 7. The opposite sides of the symmetrically distributed blocking frames 7 are all smooth surfaces. When the blocking frame 7 contacts the slitting knife 3, the friction between the blocking frame 7 and the slitting knife 3 is reduced; the cooling air duct 8 has a left-right symmetrical distribution. Two cooling ducts 8 are respectively fixed on the left and right sides of the protective shell 4, and the cooling air duct 8 is connected to the cooling fan not shown in the figure. The two cooling air ducts 8 are respectively located on the left and right sides of the slitting knife 3, and are used to cool the left and right sides of the slitting knife 3. A grinding strip 9 is fixed on the side of the blocking frame 7 close to the slitting knife 3. The grinding strip 9 is used to block impurities adhered to the slitting knife 3. Initially, there is a gap between the grinding strip 9 and the slitting knife 3. When the grinding strip 9 moves to the slitting knife 3, the grinding strip 9 fits with the slitting knife 3.

[0019] like Figure 3 and Figure 6 As shown, the protective shell 4 is fixed with baffles 10 which are symmetrically distributed and respectively located in adjacent channels thereof, the baffles 10 divide the adjacent channels on the protective shell 4 into a first chamber and a second chamber, the extrusion plate 6 and the adjacent blocking frame 7 are both located in adjacent first chambers on the protective shell 4, the distance between the second chamber of the protective shell 4 and the adjacent cooling air duct 8 is smaller than the distance between the first chamber and the adjacent cooling air duct 8, the pipe opening of the cooling air duct 8 close to the slitting knife 3 faces between the two second chambers of the protective shell 4, and the second chamber of the protective shell 4 is connected with a waste collection device which is not shown in the figure.

[0020] The specific working principle is as follows: When the operator needs to use the device to cut aluminum foil, the operator first installs several devices on the same fixed roller, and then turns on the electric slide 1 through the control terminal, so that the several electric slides 1 drive all the parts on them and slide left and right on the fixed roller (the direction is Figure 1 The main view is used as a reference) to change the distance between different electric slides 1, so as to adjust the slitting width of the aluminum foil. When the position of the electric slide 1 is adjusted, the operator closes the electric slide 1 and turns on the motor 2 through the control terminal. The output shaft of the motor 2 drives the slitting knife 3 to rotate, and the slitting knife 3 rotates to slit the aluminum foil. In the process of the slitting knife 3 slitting the aluminum foil, the operator turns on the cooling fan through the control terminal. The cooling fan conveys cold air to the left and right sides of the upper part of the slitting knife 3 through two cooling air ducts 8. In the process of the rotation of the slitting knife 3, the surface of the slitting knife 3 is cooled (in order to prevent the aluminum foil from shaking due to the blowing of cold air, the cold air cannot be directly conveyed to the contact between the slitting knife 3 and the aluminum foil) to reduce the surface temperature of the slitting knife 3, thereby reducing the probability of the slitting knife 3 continuing to heat up during the slitting process.

[0021] During the process of slitting the aluminum foil by the leftmost slitting knife 3 and the rightmost slitting knife 3 on the fixed roller, the excess material on both sides of the aluminum foil roll will be cut off, and the slitting knife 3 will rotate and rub against the aluminum foil continuously, which will cause static electricity to be generated on the surface of the slitting knife 3 and the aluminum foil, and the aluminum foil powder and debris will adhere to the slitting knife 3 due to the influence of static electricity. When the slitting knife 3 drives the aluminum foil waste adhered thereto to rotate between the two blocking frames 7 and the two grinding strips 9, the blocking frames 7 and the grinding strips 9 block the aluminum foil waste, so that the aluminum foil waste is separated from the slitting knife 3, reducing the amount of aluminum foil adhered to the slitting knife 3, and then reducing the influence of the aluminum foil adhering to the slitting knife 3 on the slitting efficiency, so as to improve the quality of aluminum foil slitting.

[0022] When the aluminum foil waste is separated from the slitting knife 3, the aluminum foil waste is separated to the vicinity of the channel of the protective shell 4, and the cooling air duct 8 conveys cold air to the left and right sides of the upper part of the slitting knife 3. The cold air carries the separated aluminum foil waste and blows the aluminum foil waste into the second chamber of the protective shell 4. Then the waste is blown out of the second chamber of the protective shell 4 by the cold air, and the waste collection device collects the aluminum foil waste.

[0023] When the aluminum foil is cut and the device needs to be stopped, the operator collects the aluminum foil rolls that have been cut (in the process of aluminum foil cutting, the cut aluminum foil is rolled up), and turns off the electric slide 1, motor 2 and cooling fan through the control terminal. If the device needs to be disassembled, the electric slide 1 is removed from the fixed roller, and finally the device is cleaned for the next use.

[0024] like Figure 4 and Figure 5 As shown, it also includes: pressure sensors 11, the number of which is the same as the number of the extrusion plates 6, and are all fixed to the protective shell 4, the pressure sensors 11 are electrically connected to the control terminal, and all the pressure sensors 11 are respectively located in different first chambers on the protective shell 4; flexible blocks 1101, the number of which is the same as the number of the pressure sensors 11, and are respectively fixed to adjacent blocking frames 7, the flexible blocks 1101 are used to squeeze the pressure sensors 11, and the protective shell 4 is provided with an alarm which is not shown in the figure and is electrically connected to the control terminal. When the slitting knife 3 is deformed or loosened due to fatigue, the slitting knife 3 shakes and squeezes the blocking frame 7, and the blocking frame 7 squeezes the pressure sensor 11 through the adjacent flexible blocks 1101. The pressure sensor 11 is pressurized and transmits an electrical signal to the control terminal, and the control terminal controls the alarm to turn on to prompt the operator that the slitting knife 3 is damaged.

[0025] like Figure 3-Figure 5 As shown, it also includes: a micro-electromagnetic slider 12, a protective shell 4 is provided with an electromagnetic slide rail, the micro-electromagnetic slider 12 is slidably connected in the electromagnetic slide rail of the protective shell 4, the electromagnetic slide rail of the protective shell 4 is electrically connected to the control terminal, the micro-electromagnetic slider 12 is fixedly connected with a first trigger plate 13 symmetrically distributed on the left and right, the first trigger plate 13 is provided with a first inclined surface, and the number of the first trigger plates 13 is the same as the number of the extrusion plates 6; the first sliding frame 14, the number is the same as the number of the first trigger plates 13, the first sliding frame 14 is provided with a second inclined surface, and is respectively fixed to the adjacent extrusion plates 6, a first reset spring is fixedly connected between the first sliding frame 14 and the protective shell 4, when the first trigger plate 13 moves downward, the first inclined surface of the first trigger plate 13 squeezes the second inclined surface of the adjacent first sliding frame 14, so that the first sliding frame 14 moves horizontally.

[0026] The specific working principle is as follows: During the process of the slitting knife 3 slitting the aluminum foil, if there is too much aluminum foil powder and debris adhering to the slitting knife 3, which affects the surface smoothness of the slitting knife 3, the operator turns on the electromagnetic slide rail of the protective shell 4 through the control terminal to move the micro electromagnetic slider 12, and the micro electromagnetic slider 12 drives all the first trigger plates 13 to move downward (at this time, the micro electromagnetic slider 12 does not need to move downward to the limit position), and the first trigger plate 13 squeezes the second inclined surface of the first sliding frame 14 through the first inclined surface, so that the first sliding frame 14 drives the squeezing plate 6 to move, and the first reset spring of the first sliding frame 14 The spring is compressed, and the extrusion plate 6 drives the blocking frame 7 to move through its first elastic member, and the blocking frame 7 moves to fit the surface of the slitting knife 3. The first elastic member of the extrusion plate 6 is compressed and contracts (the first elastic member is not compressed to the limit state at this time), and the blocking frame 7 drives the grinding strip 9 to move, so that the grinding strip 9 fits the surface of the slitting knife 3. As the slitting knife 3 rotates, the blocking frame 7 and the grinding strip 9 grind the surface of the slitting knife 3 through friction, reducing the amount of aluminum foil powder and aluminum foil debris adhering to the slitting knife 3, thereby improving the surface smoothness of the slitting knife 3, and then ensuring the quality and efficiency of aluminum foil slitting.

[0027] When the operator determines that the aluminum foil powder and aluminum foil debris adhered to the slitting knife 3 have been polished off, the operator controls the micro electromagnetic slider 12 to move and reset through the control terminal, and the micro electromagnetic slider 12 drives all the first trigger plates 13 to move and reset, and the first reset spring of the first sliding frame 14 rebounds and resets, so that the first sliding frame 14 is reset, the first elastic part of the extrusion plate 6 is gradually reset, and the blocking frame 7 and the grinding strip 9 move and reset.

[0028] When the slitting knife 3 shakes during use (due to insufficient manufacturing precision or wear and tear, the gravity distribution of the slitting knife 3 is uneven, which may cause the slitting knife 3 to shake during use), the slitting knife 3 shakes and squeezes one of the blocking frames 7, the blocking frame 7 squeezes the flexible block 1101, and the flexible block 1101 squeezes the pressure sensor 11, so that a pressure difference is generated between the two pressure sensors 11, and the two pressure sensors 11 sense the pressure difference and transmit electrical signals to the control terminal, and the control terminal controls the alarm and the micro electromagnetic slider 12 to turn on, and the alarm prompts the operator that the slitting knife 3 is damaged. At the same time, the micro electromagnetic slider 12 repeats the above steps to drive all the first trigger plates 13 to move downward (at this time, the micro electromagnetic slider 12 moves downward to the limit position), and the first trigger plate 13 moves the blocking frame 7 through the first sliding frame 14 and the squeezing plate 6 (at this time The degree of squeezing of the first elastic member between the extrusion plate 6 and the blocking frame 7 increases, and the first elastic member is compressed to the limit state). The two blocking frames 7 move together and limit the slitting knife 3, so that the slitting knife 3 is straightened by the two blocking frames 7. Under the premise that an aluminum foil roll has not been slitting, the slitting knife 3 can be temporarily used for emergency use to reduce the probability of damage and shaking of the slitting knife 3, thereby ensuring the quality of aluminum foil slitting. When an aluminum foil roll is slitting, the operator controls the micro electromagnetic slider 12 to move and reset through the control terminal, so that the first trigger plate 13 moves and resets, and the first reset spring of the first sliding frame 14 rebounds and resets, so that the first sliding frame 14 resets, and the first elastic member of the extrusion plate 6 gradually resets, and the blocking frame 7 and the grinding strip 9 move and reset. Finally, the operator closes the micro electromagnetic slider 12 through the control terminal and replaces the damaged slitting knife 3.

[0029] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, it also includes: connecting rods 15, the number of which is the same as the number of first trigger plates 13, and are respectively fixed to the adjacent first trigger plates 13, the connecting rods 15 are fixed to the second trigger plates 16, and the second trigger plates 16 are provided with a third inclined surface; second sliding frames 17, the number of which is the same as the number of second trigger plates 16, and are respectively slidably connected to the left and right sides of the protective shell 4, the upper part of the second sliding frame 17 is provided with a fourth inclined surface, and a second elastic member is fixed between the second sliding frame 17 and the protective shell 4, wherein the second elastic member between the second sliding frame 17 and the protective shell 4 is a compression spring, and the third inclined surface of the second trigger plate 16 is used to squeeze the fourth inclined surface of the adjacent second sliding frame 17 so that the second sliding frame 17 moves horizontally, and the second sliding frame 1 7 is fixedly connected with a clamping plate 18. Initially, there is a distance between the clamping plate 18 and the slitting knife 3. When the micro electromagnetic slider 12 moves downward to the limit position, the first trigger plate 13 drives the second trigger plate 16 to move downward to the limit position through the connecting rod 15. At this time, the second sliding frame 17 is squeezed to the limit state, and the clamping plate 18 fits with the slitting knife 3. The clamping plate 18 is used to limit the slitting knife 3. The clamping plate 18 and the adjacent extrusion plate 6 are distributed in sequence along the rotation direction of the slitting knife 3, that is, the distance between the clamping plate 18 and the cut aluminum foil is smaller than the distance between the adjacent extrusion plate 6 and the cut aluminum foil, so that a certain point on the slitting knife 3 will pass through the cooling air duct 8 only after passing through the clamping plate 18, and the slitting knife 3 is cooled by the cooling air duct 8.

[0030] The specific working principle is as follows: When the slitting knife 3 shakes during use, and the first trigger plate 13 moves downward to the limit position (at this time, since the micro electromagnetic slider 12 moves downward to the limit position, the first trigger plate 13 also moves to the limit position, and the first elastic member between the squeezing plate 6 and the blocking frame 7 is compressed to the limit state), the first trigger plate 13 drives the second trigger plate 16 to move downward to the limit position through the connecting rod 15, and the third inclined surface of the second trigger plate 16 squeezes the fourth inclined surface of the second sliding frame 17, so that the second sliding frame 17 moves, so that the second elastic member of the second sliding frame 17 is compressed, and the second sliding frame 17 drives the clamping The plate 18 moves, and the two clamping plates 18 gradually move towards each other. When the two clamping plates 18 move towards each other to the extreme position, the two clamping plates 18 clamp the slitting knife 3 in the middle, straighten and limit the slitting knife 3, straighten one point of the slitting knife 3 through the two blocking frames 7, and then straighten the other point of the slitting knife 3 through the two clamping plates 18, so that the two points of the slitting knife 3 are limited and straightened, so as to reduce the probability of the slitting knife 3 being bent and deformed due to excessive shaking and being limited by a single point, thereby reducing the probability of the aluminum foil being damaged by the deformed slitting knife 3, thereby ensuring the quality of the aluminum foil cut by the slitting knife 3.

[0031] When the operator controls the micro electromagnetic slider 12 to move and reset through the control terminal, so that the first trigger plate 13 moves and resets, the first trigger plate 13 drives the second trigger plate 16 to reset through the connecting rod 15, and the second elastic member of the second sliding frame 17 is reset, and the second sliding frame 17 drives the clamping plate 18 to reset.

[0032] like Figure 6 and Figure 7 As shown, the connecting rod 15 on the right side is provided with a wedge-shaped portion 19, and the wedge-shaped portion 19 is provided with a fifth inclined surface. The protective shell 4 is slidably connected to a third sliding frame 20, and the third sliding frame 20 is provided with a sixth inclined surface. When the connecting rod 15 drives the wedge-shaped portion 19 to move downward, the fifth inclined surface of the wedge-shaped portion 19 squeezes the sixth inclined surface of the third sliding frame 20, so that the third sliding frame 20 moves horizontally. A second return spring is fixedly connected between the third sliding frame 20 and the protective shell 4. The protective shell 4 is slidably connected to a sliding block 21, and the third sliding frame 20 is used to limit the sliding block 21. When the wedge-shaped portion 19 moves downward to the limit position, the third sliding frame 20 is squeezed and moved to the limit position and loses contact with the sliding block 21. The sliding block 21 is fixedly connected with a protective net 22 for shielding the lower part of the slitting knife 3, and the protective net 22 is made of a hard material (such as stainless steel).

[0033] The specific working principle is as follows: When the slitting knife 3 is shaken and the micro-electromagnetic slider 12 moves downward to the limit position, the first trigger plate 13 drives the wedge-shaped portion 19 to move downward to the limit position through the connecting rod 15. The wedge-shaped portion 19 moves downward to the limit position and squeezes the third sliding frame 20 to the left to the limit position through its fifth inclined surface. The third sliding frame 20 loses contact with the sliding block 21, and the protective net 22 loses the obstruction of the sliding block 21. The protective net 22 falls downward under the influence of its own gravity, and the protective net 22 blocks the lower part of the slitting knife 3. When the slitting knife 3 is separated from the output shaft of the motor 2 or even breaks due to excessive shaking, the protective net 22 blocks the slitting knife 3 to reduce the probability of injury to the operator caused by the splashing of the broken slitting knife 3, thereby improving the safety of the use of the device.

[0034] When the aluminum foil is cut and the device needs to be stopped, the operator collects the cut aluminum foil and repeats the above steps to make the micro electromagnetic slider 12 drive the first trigger plate 13 to reset. If the slitting knife 3 does not shake, the first trigger plate 13 drives the wedge-shaped portion 19 to reset through the connecting rod 15, and the second reset spring of the third sliding frame 20 resets the third sliding frame 20. If the slitting knife 3 is damaged and shakes, the operator replaces the slitting knife 3. At this time, after the first trigger plate 13 drives the wedge-shaped portion 19 to reset through the connecting rod 15, the operator needs to manually move forward. The third sliding frame 20 is moved to compress the second return spring of the third sliding frame 20, and the protective net 22 is manually reset upward to reset the sliding block 21 and the protective net 22. Then the operator releases the third sliding frame 20, and the second return spring of the third sliding frame 20 is reset, so that the third sliding frame 20 is reset and the sliding block 21 is limited again. Finally, the electric slide 1, the motor 2, the cooling fan and the micro electromagnetic slider 12 are turned off through the control terminal. If the device needs to be disassembled, the electric slide 1 is disassembled from the fixed roller. Finally, the device is cleaned for the next use.

[0035] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
