Description

Technical Field

[0003] The scraper device of the existing micro-gravure coating equipment generally includes two wall plates arranged opposite to each other on the left and right, a scraper mechanism, a scraper adjustment mechanism and a lifting drive mechanism. The scraper mechanism and the scraper adjustment mechanism are both located between the two wall panels. The scraper mechanism is connected to the front end of the scraper adjustment mechanism. The scraper adjustment mechanism is used to drive the scraper mechanism to move forward and backward and rotate. The lifting drive mechanism generally includes a lifting drive handwheel, a lifting reducer, a first lifting rotating shaft, a second lifting rotating shaft and two bidirectional linear bearing mounting seats arranged opposite to each other on the left. The lifting drive handwheel is connected to the input shaft of the lifting reducer. One end of the first lifting rotating shaft and the second lifting rotating shaft are respectively connected to the first output shaft and the second output shaft of the lifting reducer. The other ends of the first lifting rotating shaft and the second lifting rotating shaft are respectively rotatably arranged on the adjacent sides of the two bidirectional linear bearing mounting seats. The outer peripheries of the other ends of the first lifting rotating shaft and the second lifting rotating shaft are respectively sleeved with two gears. The rear sides of the two wall panels are respectively provided with two racks extending along the height direction of the wall panels. The two gears are respectively meshed with the two racks. A connecting shaft is provided between the two bidirectional linear bearing mounting seats, and the scraper adjustment mechanism is connected to the connecting shaft.

[0004] During actual coating, the micro-gravure roller is located in front of the scraper mechanism. The lifting and lowering driving hand wheel is rotated first, so that the first lifting and lowering rotating shaft and the second lifting and lowering rotating shaft can be driven to rotate through the lifting and lowering reducer, thereby driving the two gears to rotate. Under the action of the meshing of the two gears and the two racks, the two gears can move upward along the two racks, thereby driving the two bidirectional linear bearing mounting seats, the first lifting and lowering rotating shaft, the second lifting and lowering rotating shaft, the lifting and lowering driving hand wheel, the lifting and lowering reducer, and the connecting shaft to move upward, thereby driving the scraper adjustment mechanism to move upward, thereby driving the scraper mechanism to move upward to a predetermined position, and then the scraper adjustment mechanism drives the scraper mechanism to move forward to a predetermined position and rotate to a predetermined angle, so that the scraper mechanism can contact the micro-gravure roller with a certain pressure, and then when the micro-gravure roller rotates, the scraper mechanism can scrape off excess slurry on the micro-gravure roller.

[0005] During operation of the above-mentioned lifting drive mechanism, the lifting drive handwheel, the lifting reducer, the first lifting rotating shaft, the second lifting rotating shaft and the two gears move upward together with the scraper mechanism, thereby increasing the weight of the moving parts. In order for the operator to turn the lifting drive handwheel, the reduction ratio of the lifting reducer needs to be increased. If the reduction ratio of the lifting reducer is reduced, the upward movement speed of the scraper mechanism will be reduced, thereby increasing the positioning time of the scraper mechanism and reducing production efficiency.

[0031] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.

[0032] Please refer to Figure 1 and Figure 2 A scraper device provided by an embodiment of the utility model comprises two wall panels 10 arranged opposite to each other, a scraper mechanism 20, a scraper adjustment mechanism and a lifting drive mechanism 60. The inner side of a component described in the utility model refers to the side of the component close to the midpoint of the center line connecting the two wall panels 10, and the outer side of the component refers to the side of the component away from the midpoint of the center line connecting the two wall panels 10.

[0033] The scraper mechanism 20 and the scraper adjustment mechanism are both located between the two wall panels 10. The scraper mechanism 20 is connected to the front end of the scraper adjustment mechanism. The scraper adjustment mechanism is used to drive the scraper mechanism 20 to move forward and backward and rotate. The scraper mechanism 20 is used to contact the micro-gravure roller 100 to scrape off the excess coating slurry on the micro-gravure roller 100. The scraper adjustment mechanism is connected to the lifting drive mechanism 60. The lifting drive mechanism 60 is set at the rear side of the two wall panels 10 and is used to drive the scraper adjustment mechanism to move up and down, thereby driving the scraper mechanism 20 to move up and down.

[0034] Specific, combined Figures 3 to 5 As shown, the scraper mechanism 20 includes a scraper base plate 21 , a lower pressing plate 221 , an upper pressing plate 222 and a scraper 23 .

[0035] The upper pressing plate 222 is located at the top of the lower pressing plate 221, and the upper pressing plate 222 and the lower pressing plate are fixed together by a plurality of first fasteners. The upper pressing plate 222, the lower pressing plate 221 and the scraper base plate 21 are fixed together by a plurality of second fasteners, and the number of the second fasteners is less than the number of the first fasteners. The upper pressing plate 222 and the lower pressing plate 221 partially protrude from the front side of the scraper base plate 21. The scraper 23 is sandwiched between the upper pressing plate 222 and the lower pressing plate 221, and the scraper 23 partially protrudes from the front side of the upper pressing plate 222 and the lower pressing plate 221. The scraper 23 is made of plastic, for example, ABS (Acrylonitrile Butadiene Styrene) plastic. The scraper 23 is used to contact the micro gravure roller 100 to scrape off the excess coating slurry on the micro gravure roller 100. In actual application, the two ends of the micro gravure roller 100 are rotatably arranged on the inner sides of the two wall panels 10 and in front of the scraper mechanism 10. When the micro gravure roller 100 rotates, the scraper 23 in contact with the micro gravure roller 100 can scrape off the excess coating slurry on the micro gravure roller 100.

[0036] In this embodiment, a groove corresponding to the scraper 23 is provided at the top of the lower pressing plate 221, and the groove extends to the front side of the lower pressing plate 221, and the scraper 23 is sandwiched between the bottom of the groove and the upper pressing plate 222. The groove is provided to position the scraper 23 during assembly.

[0037] A lining knife 24 is sandwiched between the upper pressing plate 222 and the scraper 23. The lining knife 24 partially protrudes from the front side of the upper pressing plate 222 and the lower pressing plate 221. The length of the lining knife 24 is the same as the length of the scraper 23. The width of the lining knife 24 is smaller than the width of the scraper 23. The thickness of the lining knife 24 is smaller than the thickness of the scraper 23. The rear side of the lining knife 24 is flush with the rear side of the scraper 23. The front side of the lining knife 24 is located between the front side of the scraper 23 and the upper pressing plate 222 and the lower pressing plate 221. The lining knife 24 is made of stainless steel. The lining knife 24 provides support for the scraper 23, reduces the vibration of the scraper 23, and thus slows down the wear rate of the scraper 23, extending the service life of the scraper 23.

[0038] The upper pressing plate 222 and the lower pressing plate 221 are fixed together by multiple first fasteners. Specifically: a plurality of mounting holes are provided at the top of the upper pressing plate 222, and the plurality of mounting holes are spaced apart along the length direction of the upper pressing plate 222; a plurality of threaded holes corresponding to the plurality of mounting holes are provided at the top of the lower pressing plate 221, and each first fastener corresponds to a mounting hole and a threaded hole, respectively. The first fastener includes a first bolt 223, and the screw rod of the first bolt 223 is installed in the corresponding mounting hole and threaded hole. The head of the first bolt 223 abuts against the top of the upper pressing plate 222, so that the upper pressing plate 222 and the lower pressing plate 221 can be fixed together by the first bolt 223. At the same time, the head of the first bolt 223 is used to apply pressure to the top of the upper pressing plate 222, so that the scraper 23 and the lining knife 24 can be clamped by the upper pressing plate 222 and the lower pressing plate 221. In this embodiment, the mounting hole is a waist-shaped hole, and there are fourteen first fasteners. Correspondingly, the number of threaded holes and mounting holes is also fourteen respectively. It can be understood that the number of first fasteners, mounting holes, and threaded holes can be set according to actual conditions.

[0039] In an alternative solution, the first fastener includes a first screw and a first nut. The first screw is installed in the corresponding mounting hole and threaded hole. The first nut is threadedly matched with the first screw and abuts against the top of the upper pressure plate 222. In this way, the upper pressure plate 222 and the lower pressure plate 221 can be fixed together by the first screw and the first nut. At the same time, the first nut is used to apply pressure to the top of the upper pressure plate 222, so that the scraper 23 and the lining knife 24 can be clamped by the upper pressure plate 222 and the lower pressure plate 221.

[0040] The upper pressing plate 222, the lower pressing plate 221 and the scraper base plate 21 are fixed together by multiple second fasteners. Specifically: a plurality of screw holes are provided at the top of the scraper base plate 21, and the plurality of screw holes are spaced apart along the length direction of the scraper base plate 21. The rear sides of the upper pressing plate 222 and the lower pressing plate 221 are provided with a plurality of U-shaped mounting grooves 225 corresponding to the plurality of screw holes, respectively. The number of mounting grooves 225 and screw holes is less than the number of mounting holes and threaded holes. Each second fastener corresponds to a screw hole and a mounting groove 225, respectively. The second fastener includes a second bolt 226. The screw rod of the second bolt 226 is installed in the corresponding screw hole and mounting groove 225. The head of the second bolt 226 is against the top of the upper pressing plate 222. In this way, the upper pressing plate 222, the lower pressing plate 221 and the scraper base plate 21 can be fixed together by the second bolt 226. In this embodiment, there are five second bolts 226, and correspondingly, the number of screw holes and mounting grooves 225 is also five. It can be understood that the number of second bolts 226, screw holes and mounting grooves 225 can be set according to actual conditions. With this structure, when the scraper 23 needs to be replaced, the plurality of second bolts 226 can be removed from the corresponding mounting grooves 225 and screw holes respectively, and then the upper pressing plate 222, the lower pressing plate 221, the scraper 23 and the lining blade 24 are removed from the scraper bottom plate 21 as a whole, and then the pre-assembled upper pressing plate 222, the lower pressing plate 221, the scraper 23 and the lining blade 24 are placed as a whole on the top of the scraper bottom plate 21, and then the screw rods of the plurality of second bolts 226 are respectively installed in the corresponding mounting grooves 225 and screw holes and the heads of the second bolts 226 are abutted against the top of the upper pressing plate 222, and the scraper 23 is replaced. This method of replacing the scraper 23 can realize the rapid disassembly and assembly of the scraper 23, and can reduce the downtime of the equipment. The upper pressure plate 222, the lower pressure plate 221, the scraper 23 and the lining knife 24 are assembled as follows: first place the scraper 23 on the bottom of the groove of the lower pressure plate 221, then place the lining knife 24 on the top of the scraper 23 and make the back side of the lining knife 24 flush with the back side of the scraper 23, and the two ends of the lining knife 24 flush with the two ends of the scraper 23, then place the upper pressure plate 222 on the top of the lining knife 24 and the lower pressure plate 221, then install the screw rods of multiple first bolts 223 in the corresponding mounting holes and threaded holes and make the heads of the first bolts 223 butt against the top of the upper pressure plate 222, so that the scraper 23 and the lining knife 24 can be clamped by the upper pressure plate 222 and the lower pressure plate 221, and the assembly is completed.

[0041] It can be understood that when the scraper 23 needs to be replaced, the plurality of first bolts 223 can be removed from the corresponding mounting holes and threaded holes respectively, and then the upper pressing plate 222, the scraper 23, and the lining blade 24 can be removed, and then the new scraper 23 can be placed on the bottom of the groove of the lower pressing plate 221, and then the removed lining blade 24 can be placed on the top of the new scraper 23 and the rear side of the lining blade 24 can be flush with the rear side of the new scraper 23, and the two ends of the lining blade 24 can be flush with the two ends of the new scraper 23, and then the upper pressing plate 222 can be placed on the top of the lining blade 24 and the lower pressing plate 221, and then the screws of the plurality of first bolts 223 can be installed in the corresponding mounting holes and threaded holes and the heads of the first bolts 223 can be abutted against the top of the upper pressing plate 222, and the scraper 23 can be replaced. Since the number of the first bolts 223 is greater than the number of the second bolts 226, compared with the aforementioned method, the disassembly and assembly of the scraper 23 in this method of replacing the scraper 23 will be slower, which will prolong the downtime of the equipment.

[0042] In an alternative solution, the second fastener includes a second screw and a second nut. The second screw is installed in the corresponding installation groove 225 and the screw hole. The second nut is threadedly matched with the second screw and abuts against the top of the upper pressure plate 222. In this way, the upper pressure plate 222, the lower pressure plate 221 and the scraper base plate 21 can be fixed together by the second bolt 226.

[0043] The scraper adjustment mechanism includes two front and rear drive assemblies 30 arranged in a left-right relative manner and two rotation drive assemblies 40 arranged in a left-right relative manner. The two front and rear drive assemblies 30 are used to drive the scraper base plate 21 to move forward and backward, thereby driving the upper pressing plate 222 and the lower pressing plate 221 to move forward and backward, and then driving the scraper 23 and the backing knife 24 to move forward and backward. The two rotation drive assemblies 40 are used to drive the scraper base plate 21 to rotate, thereby driving the upper pressing plate 222 and the lower pressing plate 221 to rotate, and then driving the scraper 23 and the backing knife 24. Through the rotation of the scraper 23, the scraper 23 can contact the micro-gravure roller 100 with a certain pressure, so as to facilitate scraping off the excess slurry on the micro-gravure roller 100.

The first right angle commutator 65a and the second right angle commutator 65b are both bevel gear right angle commutators, which are existing structures, and their structures and working principles are not described here. Two lifting screws 66 are respectively located at the rear of the two wall panels 10, one end of the two lifting screws 66 is respectively connected to the output shaft of the first right angle commutator 65a and the output shaft of the second right angle commutator 65b, and the other ends of the two lifting screws 66 extend upward and are rotatably arranged at the rear side of the two wall panels 10 through the bearing seats 661.

The connecting shaft 50 is arranged between the two lifting nut seats 67 . By rotating the lifting drive hand wheel 61, the input shaft of the lifting reducer 63 can be driven to rotate, and then the first output shaft and the second output shaft of the lifting reducer 63 can drive the transmission rod 64 and the input shaft of the second right-angle commutator 65b to rotate, and then the input shaft of the first right-angle commutator 65a can be driven to rotate, and then the output shaft of the first right-angle commutator 65a and the output shaft of the second right-angle commutator 65b can drive the two lifting screw rods 66 to rotate, and the rotation of the two lifting screw rods 66 can drive the two lifting nut seats 67 to move up and down, thereby driving the connecting shaft 50 to move up and down, and the up and down movement of the connecting shaft 50 can drive the fixed seat 31 of the two front and rear drive assemblies 30 to move up and down, and then other components of the two front and rear drive assemblies 30, the two rotating drive assemblies 40 and the scraper bottom plate 21 can be driven to move up and down, and then the upper pressure plate 222, the lower pressure plate 221, the scraper 23 and the lining knife 24 can be driven to move up and down.

[0056] The two lifting nut seats 67 are respectively slidably arranged on the rear side of the wall panel 10. Specifically, two slide rails 671 are respectively arranged on the rear side of the two wall panels 10. The length direction of the slide rails 671 is the same as the height direction of the wall panel 10.

[0057] In this embodiment, the lifting screw 66 is a trapezoidal screw, and the lifting nut seat 67 has a threaded hole 674 passing through the top and bottom ends thereof.

The lifting nut seat 67 is sleeved on the outer periphery of the corresponding trapezoidal screw through the threaded hole 674, and the internal thread of the threaded hole 674 is matched with the external thread of the trapezoidal screw.

[0058] It is understandable that the trapezoidal screw can also be replaced by a ball screw, and the internal thread of the threaded hole 674 of the lifting nut seat 67 is compatible with the external thread of the ball screw.

[0059] Combination Figures 7 to 11 As shown, the connecting shaft 50 is rotatably arranged between the two lifting nut seats 67, so that the connecting shaft 50 can rotate relative to the two lifting nut seats 67. Specifically, the lifting nut seats 67 have mounting holes running through the inner and outer sides thereof, and the mounting holes are located behind the threaded holes 674. The two ends of the connecting shaft 50 are respectively rotatably arranged in the mounting holes of the two lifting nut seats 67 and the two ends of the connecting shaft 50 protrude from the outer sides of the two lifting nut seats 67 respectively. Bearings 673 are provided in the mounting holes, and the bearings 673 of the two lifting nut seats 67 are respectively sleeved on the outer peripheries of the two ends of the connecting shaft 50 to provide rotation support for the connecting shaft 50.

[0060] The utility model also includes an angle adjustment mechanism 70, which includes an angle adjustment hand wheel 71 and an angle adjustment reducer 73. The angle adjustment reducer 73 is a worm gear reducer. Among the two lifting nut seats 67, the lifting nut seat 67 located on the right has a support plate 74 at its bottom end, and the support plate 74 has a through hole for the lifting screw 66 located on the right to pass through. The angle adjustment reducer 73 is arranged on the top of the support plate 74, and the angle adjustment hand wheel 71 is located behind the angle adjustment reducer 73. The peripheral sleeve of the input shaft of the angle adjustment reducer is provided with a connecting rod 72, and one end of the connecting rod 72 is connected to the angle adjustment hand wheel 71, so that the angle adjustment hand wheel 71 is connected to the input shaft of the angle adjustment reducer 73 through the connecting rod 72, and the end of the connecting shaft 50 close to the angle adjustment reducer 73 is connected to the output shaft of the angle adjustment reducer 73. By rotating the angle adjustment hand wheel 71, the input shaft of the angle adjustment reducer 73 can be driven to rotate, and then the output shaft of the angle adjustment reducer 73 can drive the connecting shaft 50 to rotate, and then the fixing seat 31 of the two front and rear drive assemblies 30 can be driven to rotate, and then the other components of the two front and rear drive assemblies 30, the two rotating drive assemblies 40 and the scraper bottom plate 21 can be driven to rotate, and then the upper pressing plate 222, the lower pressing plate 221, the scraper 23 and the backing knife 24 can be driven to rotate, so as to adjust the angle of the scraper 23 relative to the micro-gravure roller 100. When the lifting nut seat 67 located on the right moves up and down, the lifting nut seat 67 can drive the support plate 74, the angle adjustment hand wheel 71, and the angle adjustment reducer 73 to move up and down.

[0061] Through the above structure, when the utility model is actually applied, the lifting drive hand wheel 61 is first rotated, so that the lifting screw rod 66 can be driven to rotate, so that the two lifting nut seats 67 can be driven to move upward, and then the fixing seats 31 of the two front and rear drive assemblies 30 can be driven to move upward through the connecting shaft 50, and then the other parts of the two front and rear drive assemblies 30 and the two rotating drive assemblies 40 can be driven to move upward, and then the scraper bottom plate 21 and the scraper 23 can be driven to move upward to the predetermined position, and then the front and rear driving hand wheels 32 of the two front and rear drive assemblies 30 are rotated, so that the corresponding front and rear screw rods 33 can be driven. The front and rear nut seats 34 can drive the corresponding sliding seats 36 to slide forward, thereby driving the scraper base plate 21 and the two rotary drive assemblies 40 to move forward, thereby driving the scraper 23 to move forward to a predetermined position, and then the cylinders 41 of the two rotary drive assemblies 40 respectively drive the corresponding connecting seats 43 to move in a direction away from the cylinders 41, thereby driving the scraper base plate 21 to rotate counterclockwise around the axes of the two scraper rotating shafts 212, thereby driving the scraper 23 to rotate counterclockwise, so that the scraper 23 can contact the micro-gravure roller 100 with a certain pressure, such as Figure 2As shown, when the micro gravure roller 100 rotates, the excess slurry on the micro gravure roller 100 can be scraped off by the scraper 23. If it is necessary to adjust the angle of the scraper 23 relative to the micro gravure roller 100, the angle adjustment hand wheel 71 is first rotated before the front and rear driving hand wheels 32 of the two front and rear driving assemblies 30 are rotated, so that the connecting shaft 50 can be driven to rotate, and then the two front and rear driving assemblies 30 and the two rotating driving assemblies 40 can be driven to rotate, and then the scraper bottom plate 21 and the scraper 23 can be driven to rotate. After the scraper 23 rotates to a predetermined angle, the front and rear driving hand wheels 32 of the two front and rear driving assemblies 30 are rotated.

[0062] The lifting drive mechanism 60 of the utility model is provided with a transmission rod 64, a first right-angle commutator 65a, a second right-angle commutator 65b, two lifting screw rods 66 and two lifting nut seats 67. In actual application, by rotating the lifting drive hand wheel 61, the two lifting screw rods 66 can be driven to rotate through the lifting reducer 63, the transmission rod 64, the first right-angle commutator 65a, and the second right-angle commutator 65b. The rotation of the two lifting screw rods 66 can drive the two lifting nut seats 67 to move upward, thereby driving the connecting shaft 50 to move upward, and then driving the scraper adjustment mechanism to move upward, and then driving the scraper mechanism 20 to move upward. In this process, the lifting drive The hand wheel 61, the lifting reducer 63, the transmission rod 64, the first right angle commutator 65a, the second right angle commutator 65b, and the two lifting screws 66 will not move with the two lifting nut seats 67, so that only the two lifting nut seats 67 move upward with the scraper mechanism 20. Compared with the prior art, the weight of the moving parts is reduced, so that the reduction ratio of the lifting reducer 63 can be reduced. By reducing the reduction ratio of the lifting reducer 63, the rotation speed of the two lifting screws 66 can be increased, and then the speed of the two lifting nut seats 67 moving upward can be increased, and then the speed of the scraper mechanism 20 moving upward can be increased, shortening the positioning time of the scraper mechanism 20 and improving production efficiency. At the same time, this can make the entire lifting drive mechanism 60 more compact.

[0063] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
