Description

Technical Field

[0001] The invention belongs to the technical field of composite film deviation-correcting devices, and in particular relates to a mechanical deviation-correcting device for manufacturing medicinal composite films. Background Art

[0002] Medical composite film is a kind of composite roll film, the most frequently produced composite roll film, and the main one for packaging medicines, because medicine protection is very important. The web-correcting machine is often used for web-correcting equipment of heat-sealing and heat-cutting bag-making machines and printing machines; the web-correcting machine transmits signals to the web-correcting controller based on the electric eye, and then the controller outputs the web-correcting signal to the stepping motor of the web-correcting machine. The stepping motor drives the bottom screw of the machine to move according to the control signal, thereby achieving the web-correcting effect.

[0003] When the medicinal composite film is being conveyed, although the existing correcting device has a certain correcting effect on the composite film, the fixed correcting structure design cannot be adaptively adjusted for composite films of different weights or widths. In addition, the change in friction between the composite film and the correcting device causes the sensitivity of the lower belt correction to become lower, which may also cause technical problems such as failure of the correcting device. At the same time, there is no corresponding cleaning mechanism during the conveying process of the composite film. After working for a long time, electrostatic friction will be generated with the correcting roller, which will lead to technical problems such as particle dust adsorption, thereby affecting the improvement of product quality. Summary of the invention

[0004] The purpose of the present invention is to provide a mechanical correction device for the manufacture of medicinal composite films, so as to solve the technical problems that the fixed correction structure design cannot be adaptively adjusted, and the friction between the composite film and the correction device changes, resulting in a lower sensitivity of the lower belt correction, which will also cause the correction device to fail.

[0009] An air blowing cleaning mechanism, the air blowing cleaning mechanism includes a rotating wheel placed on a frame, the rotating wheel and the output shaft of a second motor are connected via a second conveyor belt transmission, one end of the rotating wheel passes through the frame and extends to the rolling groove of the other side frame, both ends of the rotating wheel are fixedly connected with cams, the top of the cam contacts and fits on a lifting plate, the lifting plate and the extension section of the frame are connected via a first spring, and one end of the lifting plate is fixed on a first gear plate, and the outer wall of the first gear plate is meshed with a fourth rotating tooth fixed on the rotating shaft.

[0010] Furthermore, both ends of the rotating shaft extend to the frame, and a jet pipe adapted thereto is mounted on the rotating shaft, and the jet pipe and the air pump are connected via a corrugated hose.

[0011] Furthermore, it also includes a conveying correction mechanism placed between the guide cleaning mechanism and the air blowing cleaning mechanism, the conveying correction mechanism includes a support frame placed on the bottom plate, the top of the support frame is connected to a first correction wheel through a first telescopic rod, both sides of the first correction wheel are connected to a second correction wheel through a second telescopic rod, the second correction wheel and the second telescopic rod are connected by a second spring, and the first correction wheel and the second correction wheel are symmetrically arranged with both ends opening outward.

[0012] Furthermore, the first telescopic rod and the second telescopic rod are maintained to be vertically arranged, and U-shaped frames are correspondingly installed on the first deviation correcting wheel and the second deviation correcting wheel.

[0013] Furthermore, a third motor is fixedly mounted on the support frame, and an output shaft of the third motor extends to the turntable and the fifth gear in sequence. The protrusion on the turntable and the push block are connected by a swing rod. The push block has a limiting groove along the height direction of the inner wall of the support frame, and the top of the push block extends to the first deviation correcting wheel. Both sides of the swing rod are mounted on the push block and the turntable by a rotating connection.

[0014] Furthermore, both upper and lower ends of the fifth rotating tooth are meshed with a second gear plate that moves in the opposite direction, and one end of the second gear plate is correspondingly connected to the second telescopic rod.

[0015] Furthermore, one end of the second gear plate is connected with a socket near the second telescopic rod and is connected by plug-in installation. As the third motor is started, the pushing block drives the first correcting wheel to move up and down, and at the same time, the second gear plate drives the second correcting wheel to move toward the center or separate.

[0016] Furthermore, brush plates are mounted on the upper cleaning roller and the lower cleaning roller by bonding, and a cleaning cavity connected to the medicinal composite film is formed between the brush plates.

At the same time, with the help of the driving mechanism, a power source can be provided for the guide cleaning mechanism and the air blowing cleaning mechanism, thereby avoiding the need for additional power, saving resources, and being environmentally friendly.

[0019] (2) A guiding cleaning mechanism is provided. After the first motor is started, the first conveyor belt can be used to drive the first rotating tooth to rotate. Then, through the gear meshing transmission, the second rotating tooth and the third rotating tooth in the vertical direction rotate in the opposite direction. Then, the lower cleaning roller and the upper cleaning roller rotate synchronously. In this way, the brush plate can rotate in the opposite direction to the advancing direction of the composite film.

[0020] (3) An air blowing cleaning mechanism is provided. After the second motor is started, it can drive the rotation of the rotating wheel through the second conveyor belt, thereby driving the cam to rotate synchronously. In conjunction with the first spring, the rotational motion of the cam can be converted into the up and down movement of the lifting plate. During the movement of the lifting plate, the fourth rotating tooth can be driven to move, thereby allowing the jet pipe on the rotating shaft to rotate at a certain angle. Through the back-and-forth jet rotation motion, the airflow is effectively and fully in contact with the surface of the composite membrane, thereby further effectively removing particulate impurities on the surface of the composite membrane and improving the applicability of the device.

[0021] (4) A conveying correction mechanism is set up to adapt to composite films of different weights and widths. When the width of the composite film is larger, the overall weight of the composite film will increase accordingly, and the friction between the composite film and the correction roller will increase. At the same time, the downward pressure on the correction roller will also increase. At this time, the third motor is started, which can drive the rotation of the turntable and the fifth gear at the same time. During the rotation of the turntable, the push block will drive the first correction wheel to move upward, and the second correction wheels on both sides can move outward synchronously. In this way, it can adapt to composite films of different sizes while reducing friction resistance. At the same time, it can also prevent the position of the correction roller from deviating, and have a corresponding correction effect on it, which effectively improves the accuracy of the correction effect and improves the stability of the device operation.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0032] Reference Manual Attached Figure 1 and Figure 2As shown, a mechanical deviation-correcting device for manufacturing a medicinal composite film comprises:

[0033] A feeding roller 1 and a receiving roller 2 are respectively provided with a first motor 3 and a second motor 4 which are adapted thereto. The feeding roller 1 and the receiving roller 2 are provided so that the composite film can be transported and wound accordingly under the action of the first motor 3 and the second motor 4. At the same time, with the aid of a driving mechanism, a power source can be provided for the guide cleaning mechanism 5 and the air blowing cleaning mechanism 12, thereby avoiding the need for additional power, saving resources, and being environmentally friendly.

[0034] The guiding cleaning mechanism 5 comprises a first rotating tooth 6, a central axis on the first rotating tooth 6 and an output shaft of the first motor 3 are connected by a first conveyor belt 7, an outer wall of the first rotating tooth 6 is meshed with a third rotating tooth 9 which is meshed with the second rotating tooth 8, the first rotating tooth 6, the second rotating tooth 8 and the third rotating tooth 9 are arranged in an L shape, and one end of the second rotating tooth 8 and the third rotating tooth 9 are respectively connected to an upper cleaning roller 10 and a lower cleaning roller 11 placed on the frame.

[0035] Specifically, the composite film can maintain the same direction of rotation and transportation under the action of the first motor 3. After the first motor 3 is started, it can drive the rotation of the first rotating tooth 6 under the action of mechanical transmission. The L-shaped second rotating tooth 8 and the third rotating tooth 9 are arranged, so that the lower cleaning roller 10 and the upper cleaning roller 11 can maintain rotation in the opposite direction of the composite film conveying direction. In this way, the particles attached to the composite film can be effectively removed by increasing the friction resistance. At the same time, the brush plate installed by bonding can also facilitate the maintenance and replacement of the brush plate, which is convenient for personnel to operate.

[0036] In addition, the cleaning chamber between the lower cleaning roller 10 and the upper cleaning roller 11 can not only clean the composite film, but also provide a corresponding activity space for the conveyance of the composite film, thereby avoiding interference between transmission parts.

[0037] A guiding cleaning mechanism 5 is provided. After the first motor 3 is started, the first rotating tooth 6 can be driven to rotate through the first conveyor belt 7, and then the second rotating tooth 8 and the third rotating tooth 9 in the vertical direction are rotated in the opposite direction through the gear meshing transmission action, so that the lower cleaning roller 10 and the upper cleaning roller 11 are rotated synchronously, so that the brush plate can keep rotating in the opposite direction to the advancing direction of the composite film, thereby making the cleaning work more effective by increasing the friction force, so that the particulate impurities on the surface of the composite film are effectively removed, thereby improving the cleanliness of the product surface.

[0038] refer to Figure 2 and Figure 4, the air blowing cleaning mechanism 12 includes a rotating wheel 13 placed on the frame, the rotating wheel 13 and the output shaft of the second motor 4 are connected by a second conveyor belt 14, one end of the rotating wheel 13 passes through the frame and extends to the rolling groove of the other side frame, both ends of the rotating wheel 13 are fixedly connected with cams 15, the top of the cam 15 contacts and fits on the lifting plate 16, the lifting plate 16 and the extension section of the frame are connected by a first spring 17, and one end of the lifting plate 16 is fixed on the first gear plate 18, and the outer wall of the first gear plate 18 is meshed with a fourth rotating tooth 19 fixed on the rotating shaft.

[0039] After the second motor 4 is started, it can drive the rotation of the rotating wheel 13 through the second conveyor belt 14. The two ends of the rotating wheel 13 are respectively connected to the frame rolling grooves on both sides, so that the cams 15 at both ends can be driven to rotate. When the cams 15 rotate, they can drive the lifting plate 16 on the first spring 17 to move up and down. During the up and down movement of the lifting plate 16, the rotating shaft on the fourth rotating tooth 19 can be rotated back and forth for adjustment, so that the jet pipe 20 can also move synchronously therewith, and can perform jetting work at different angles, so that the airflow is effectively and evenly sprayed onto the composite film, and the setting of the corrugated hose 22 utilizes the elastic function of its own material to ensure the normal rotation of the jet pipe 20.

[0040] An air blowing cleaning mechanism 12 is provided. After the second motor 4 is started, it can drive the rotating wheel 13 to rotate through the second conveyor belt 14, thereby driving the cam 15 to rotate synchronously. In conjunction with the first spring 17, the rotational motion of the cam 15 can be converted into the up and down movement of the lifting plate 16. During the movement of the lifting plate 16, the fourth rotating tooth 19 can be driven to move, thereby allowing the jet pipe 20 on the rotating shaft to rotate at a certain angle. Through the back and forth jet rotation motion, the airflow is effectively and fully contacted with the surface of the composite membrane, thereby further effectively removing the particulate impurities on the surface of the composite membrane, thereby improving the applicability of the device.

[0041] In addition, both ends of the rotating shaft extend to the frame, and a jet pipe 20 compatible with it is installed on the rotating shaft. The jet pipe 20 and the air pump 21 are connected by a corrugated hose 22. Both ends of the corrugated hose 22 can be installed on the jet pipe 20 and the air pump 21 by threaded connection. This can effectively facilitate rapid installation work between structural parts and ensure stable connection.

[0042] refer to Figure 1 , Figure 3 , Figure 5 , Figure 6 and Figure 7A mechanical deflection correction device for manufacturing a medicinal composite film also includes a conveying deflection correction mechanism 23 placed between the guide cleaning mechanism 5 and the air blowing cleaning mechanism 12. The conveying deflection correction mechanism 23 includes a support frame 24 placed on a bottom plate. The top of the support frame 24 is connected to a first deflection correction wheel 26 through a first telescopic rod 25. Both sides of the first deflection correction wheel 26 are connected to second deflection correction wheels 28 through second telescopic rods 27. The second deflection correction wheel 28 and the second telescopic rod 27 are connected by a second spring 29, and the first deflection correction wheel 26 and the second deflection correction wheel 28 are symmetrically arranged with both ends opening outward.

[0043] Specifically, the first telescopic rod 25 and the second telescopic rod 27 are vertically arranged, and U-shaped frames are installed on the first correcting wheel 26 and the second correcting wheel 28 respectively. The first telescopic rod 25 is mainly used to auxiliary support the first correcting wheel 26, and can drive the first correcting wheel 26 to move up and down normally. The second telescopic rod 27 is mainly used to support and connect the second correcting wheel 28, and can also help the second correcting wheels 28 on both sides to synchronously align and move in opposite directions. The above-mentioned first telescopic rod 25 and second telescopic rod 27 can adapt to composite films of different widths, and can also prevent the composite film from deviating from its position during transportation.

[0044] A third motor 30 is fixedly mounted on the support frame 24, and the output shaft of the third motor 30 extends to the turntable 31 and the fifth gear 32 in sequence. The protrusion on the turntable 31 and the push block 33 are connected by a swing rod 34. The push block 33 has a limiting groove 35 along the height direction of the inner wall of the support frame 24, and the top of the push block 33 extends to the first deviation correcting wheel 26. Both sides of the swing rod 34 are installed on the push block 33 and the turntable 31 by a rotating connection.

[0045] A conveying and correcting mechanism 23 is set to adapt to composite films of different weights and widths. When the width of the composite film is large, the overall weight of the composite film will also increase, and the friction between the composite film and the correcting roller will increase, and the downward pressure on the correcting roller will also increase. At this time, the third motor 30 is started, which can simultaneously drive the rotation of the turntable 31 and the fifth rotating tooth 32. During the rotation of the turntable 31, the pushing block 33 will drive the first correcting wheel 26 to move upward, and the second correcting wheels 28 on both sides can move outward synchronously, which can adapt to composite films with larger width and heavier weight. Conversely, during the rotation of the turntable 31, the pushing block 33 will drive the first correcting wheel 26 to move downward, and the second correcting wheels 28 on both sides can move inward synchronously, which can adapt to composite films with smaller width and lighter weight. In this way, it can adapt to composite films of different sizes while reducing frictional resistance, and can also prevent the position of the correcting roller from deviating, which has a corresponding correction effect on it, effectively improving the accuracy of the correction effect and improving the stability of the device operation.

[0046] In addition, both upper and lower ends of the fifth rotating tooth 32 are meshed with a second gear plate 36 that moves in the opposite direction. One end of the second gear plate 36 is correspondingly connected to the second telescopic rod 27. One end of the second gear plate 36 is connected to a socket close to the second telescopic rod 27 and is connected by plug-in installation. As the third motor 30 is started, the push block 33 drives the first deviation correcting wheel 26 to move up and down. At the same time, the second gear plate 36 drives the second deviation correcting wheel 28 to move toward the center or separate. Brush plates are installed on the upper cleaning roller 10 and the lower cleaning roller 11 by bonding, and a cleaning cavity connected to the medicinal composite film is formed between the brush plates.
