Description

Technical Field

[0001] The invention relates to the technical field of thickness gauges, in particular to a thickness gauge for a coating machine. Background Art

[0002] When producing plasters, the ointment is applied to the surface of the film material through a coating machine. The coating machine is mainly used for the surface coating process of thin films, paper, etc., and a layer of coating with specific functions is applied to the rolled film material. However, the coating machine often causes poor product quality due to uneven thickness of the ointment applied. Therefore, a thickness gauge is used to measure the coating thickness on the surface of the film material.

[0003] At present, the detection end of the thickness gauge needs to contact the surface of the film material for detection. Since the film material is elastic, the detection end is easy to press the film material when contacting the film material, causing the film material to deform, making the thickness detection of the paste inaccurate, and causing the result of the paste thickness detection to deviate. In addition, when the detection end contacts the film material, it is easy to damage the surface of the film material, thereby affecting the quality of the produced products.

[0016] By means of the above technical solution, the present invention provides a thickness gauge for a coating machine, which has at least the following beneficial effects compared with the prior art:

[0017] 1. The present invention provides a measuring mechanism to accurately measure the paste on the surface of film materials of different sizes. Through the cooperation of the driving component and the locking component, the thickness sensor 1 on the movable frame is adjusted to a precise position, and then the thickness sensor 1 and the movable frame are stably installed on the limit cross bar at the same time. Accurate measurement can be performed without contacting the surface of the film material, which improves the measurement accuracy and does not damage the surface of the film material. At the same time, film materials of different sizes can be measured, which expands the application range of the thickness gauge and avoids the situation where the inaccurate measurement of the paste thickness on the film material affects the measurement accuracy.

[0018] 2. The present invention fixes the thickness sensor 1 and the movable frame on the limiting cross bar at the same time by setting a locking assembly. After the position of the thickness sensor 1 is determined, the movable connecting rod is pulled to insert one end of the thickness sensor 1 into the positioning seat. At the same time, the movable connecting rod pushes the movable clamping rod downward through the trapezoidal block, and the bottom end of the movable clamping rod is inserted into the corresponding limiting clamping frame. After the movable pressure block lacks the resistance of the movable connecting rod, the spring 2 pushes the movable pressure block to move upward, and one side of the movable pressure block presses against the end of the movable connecting rod, so that the thickness sensor 1 is fixed on the movable frame, and the movable frame is fixed on the limiting cross bar at the same time, which is more convenient to operate and is conducive to more stable installation of the thickness sensor 1, thereby improving the measurement accuracy of the thickness sensor 1 and improving the practicality of the thickness gauge.

[0019] 3. The present invention can adjust the actual measuring position of the thickness sensor 1 by setting a driving component to drive the movable frame to move on the limit rack, and drive the transmission gear to move on the limit rack through the servo motor, thereby driving the movable frame to move. The transmission gear and the limit rack themselves have an interlocking function, and the movable frame can only be driven by the servo motor, thereby avoiding the problem of the thickness sensor 1 being affected by external vibration and shaking during measurement and affecting the measurement accuracy, which is beneficial to reducing the unqualified rate of ointment products.

[0020] 4. The present invention monitors the running state of the film material by setting up a monitoring mechanism. During the film coating and winding process, the verticality sensors on the two movable cross bars are used to monitor the running process of the film material. When the film material deviates, it can be detected by the verticality sensor, and then the deviation correction device in the coating machine body is used to correct the deviation, which can keep the film material fine-tuned in time, ensure the accuracy of the detection position of the thickness sensor, and further improve the measurement accuracy of the thickness gauge.

[0021] 5. The present invention sets a linkage component to enable the verticality sensor to move in the vertical direction while moving horizontally. The vertical height of the verticality sensor is adjusted while adjusting the distance between the two verticality sensors according to the different sizes of the membrane materials, so as to monitor the operating status of the membrane materials of different sizes. At the same time, a thickness sensor is set to perform secondary thickness monitoring, so that the staff can find problems in time and make fine adjustments according to the conditions of the membrane materials, thereby reducing the waste of membrane materials and coating pastes.

[0037] 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.

[0038] The drug or herbal ingredients are fully mixed with the adhesive, and then coated on the film material by a coating machine to make a plaster. The plaster is attached to the affected area to locally release the drug ingredients to achieve the effect of local treatment. It can be used to relieve pain, reduce muscle fatigue, relieve arthritis and other symptoms. The advantage of using the plaster is that it can directly act on the painful or uncomfortable parts, and has the characteristics of strong penetration and fast absorption. In order to ensure that the coating machine evenly coats the plaster on the film material, a thickness gauge is designed to measure the thickness of the plaster on the surface of the film material to prevent the problem of poor quality of the plaster product caused by uneven plaster coating thickness.

[0039] This device is designed for the coating production of plaster and patch coating machines, and can also be used for other coating coating machines. Its scope of application can be improved and expanded.

[0040] First embodiment

[0041] Reference Figure 1-Figure 6 In order to more accurately measure the thickness of the ointment coated on the film material without touching the ointment on the surface of the film material, so as to avoid the problem of uneven thickness of the coated ointment affecting the quality of the patch product, a thickness gauge for a coating machine is provided, including a coating machine body 1, a supporting platform 2 installed on the coating machine body 1, and a measuring mechanism 3 located on the supporting platform 2. Shock-absorbing pads are fixed at the positions where the two ends of the bottom of the supporting platform 2 contact the coating machine body 1, so as to reduce the influence of vibration of the coating machine body 1 during operation on the measurement accuracy. The measuring mechanism 3 is used to measure the thickness of the ointment on the surface of the film materials of different sizes.

[0042] The coating machine body 1 is also provided with a correction device for maintaining the normal operation of the film material without deviation. The top of the support platform 2 can also be removably installed with a spirit level to keep the support platform 2 installed level. At the same time, the top of the support platform 2 is also provided with a dust cover for providing certain protection for the measuring mechanism 3.

[0043] The measuring mechanism 3 is used to accurately measure the paste on the surface of membrane materials of different sizes. Through the cooperation of the driving component 37 and the locking component 36, the thickness sensor 34 on the movable frame 33 is adjusted to a precise position, and then the thickness sensor 34 and the movable frame 33 are stably installed on the limiting cross bar 31 at the same time. Accurate measurement can be performed without contacting the surface of the membrane material, thereby improving the measurement accuracy and not damaging the surface of the membrane material.

[0044] Since the detection end of the existing thickness gauge is easy to press the film material when it contacts the film material, causing the film material to deform, the thickness measurement of the paste on the film material is not accurate. In order to improve the measurement accuracy of the thickness gauge, specifically, the measuring mechanism 3 includes a limit cross bar 31 arranged on the top of the support platform 2, and a limit rack 32 arranged on one side of the limit cross bar 31, and the limit cross bar 31 and the limit rack 32 are both detachable and arranged on the support platform 2, and the two ends of the limit cross bar 31 and the limit rack 32 are respectively fixed at the same time by two fixing parts, and the limit cross bar 31 and the limit rack 32 can be disassembled and assembled synchronously, which is convenient for cleaning after long-term use. Three equally spaced movable frames 33 are provided, a thickness sensor 34 is provided at one end of the movable frame 33, and the thickness sensor 34 penetrates the movable frame 33 and is slidably connected thereto, twenty-four equally spaced limit frames 35 are fixed on the top of the limit cross bar 31, and a locking assembly 36 is provided on the movable frame 33 for fixing it and the thickness sensor 34 on the limit cross bar 31 at the same time, which is conducive to more convenient installation and disassembly of the thickness sensor 34, and keeps it more stable during installation, thereby improving its measurement accuracy, and the movable frame 33 moves to a suitable position on the limit cross bar 31, and a corresponding limit frame 35 will be provided at the bottom of the movable frame 33 corresponding to it.

[0045] After determining the measuring position of the thickness sensor 34, in order to fix the thickness sensor 34 on the limiting cross bar 31 to measure the thickness of the film material paste, the movable frame 33 is fixedly installed on the limiting cross bar 31 by the locking assembly 36, and the thickness sensor 34 is further fixed. Specifically, it includes a movable connecting rod 361 arranged on the movable frame 33, and a positioning seat 362 fixed on the thickness sensor 34 and matched with one end of the movable connecting rod 361. The movable frame 33 is respectively provided with a vertical groove 1 363 and a vertical groove 2. The vertical groove 1 363 is on the side of the vertical groove 2 close to the thickness sensor 34, and the vertical groove 363 is on the side of the vertical groove 2 close to the thickness sensor 34. A movable clamping rod 364 is slidably provided on the inner side of the movable clamping rod 363, and the bottom end of the movable clamping rod 364 is matched with any one of the limit clamping frames 35. A trapezoidal block 365 fixed to the movable connecting rod 361 is provided on the top of the movable clamping rod 364, and the ends of the trapezoidal block 365 and the movable clamping rod 364 close to each other are respectively provided with matching inclined surfaces. A spring 366 in contact with the bottom of the movable frame 33 is fixed on one side of the movable clamping rod 364. When the thickness sensor 34 is fixed, the spring 366 is in a stretched state. A movable pressing block 367 with a bottom end slidably connected to the second vertical groove is provided at the end of the movable connecting rod 361 away from the positioning seat 362. The cross section of the movable pressing block 367 is Figure 6As shown, a spring 2 368 in contact with the bottom wall of the second vertical slot is fixed at the bottom of the movable pressing block 367, and a limit seat 369 detachably mounted on the movable frame 33 is slidably provided in the middle of the movable connecting rod 361. The movable connecting rod 361 penetrates the limit seat 369 and is slidably connected. When the movable pressing block 367 is pressed downward, the bottom end of the movable pressing block 367 slides downward in the second vertical slot, and the movable pressing block 367 squeezes the spring 2 368. The spring 2 368 is elastically deformed and compressed, and the movable pressing block 367 is pressed downward. One side of block 367 is separated from one end of the movable connecting rod 361, and at the same time, spring 1 366 restores its elastic deformation to push the movable clamping rod 364 to move upward, and the movable clamping rod 364 pushes the trapezoidal block 365 on its top to move in the horizontal direction, and the trapezoidal block 365 pushes the movable connecting rod 361 to move in the direction of the movable pressure block 367, and one end of the movable connecting rod 361 presses the movable pressure block 367, and the movable pressure block 367 squeezes the spring 2 368, and the spring 2 368 produces elastic deformation and is compressed.

[0046] By pulling the movable link 361, one end of the movable link 361 is inserted into the positioning seat 362, and the movable link 361 drives the trapezoidal block 365 to move downward, and the trapezoidal block 365 pushes the movable clamping rod 364 to slide downward in the vertical slot 1 363, and the bottom end of the movable clamping rod 364 is inserted into the inner side of the corresponding limit clamping frame 35, and the movable clamping rod 364 drives the bottom end of the spring 1 366 to move downward, and the spring 1 366 is elastically deformed and stretched. At the same time, after the movable pressure block 367 lacks the resistance of the movable link 361, the spring 2 368 By restoring the elastic deformation, the spring 2 368 pushes the movable pressure block 367 to move upward, and one side of the movable pressure block 367 presses against the end of the movable connecting rod 361, so that the thickness sensor 1 34 is fixed on the movable frame 33, and the movable frame 33 is simultaneously fixed on the limiting cross bar 31. Through one operation step, the thickness sensor 1 34 and the movable frame 33 are fixed on the limiting cross bar 31 at the same time, which is easy to operate and helpful for the staff to use, and improves the installation stability of the thickness sensor 1 34 and its measurement accuracy.

[0047] Second embodiment

[0048] Reference Figure 3 - Figure 4In order to measure membrane materials of different sizes without manually adjusting the measuring position of the thickness sensor 34, the position of each thickness sensor 34 is controlled separately, the measurement coverage is larger and more accurate, and the advantages of continuous monitoring without manual intervention can be achieved. Specifically, the measuring mechanism 3 also includes a driving assembly 37 arranged on the movable frame 33 for driving it to move on the rack. The driving assembly 37 includes a transmission gear 371 arranged on the inner side of the middle part of the movable frame 33 and meshing with the limit rack 32. A transmission shaft 372 is fixed at the axis of the transmission gear 371, and the transmission shaft 372 has two ends.

The servo motor 373 drives the transmission gear 371 to move on the limit rack 32, thereby driving the movable frame 33 to move. The transmission gear 371 and the limit rack 32 themselves have an interlocking function. The movable frame 33 can only be driven by the servo motor 373. No manual adjustment is required, thereby preventing the thickness measuring sensor 34 from affecting the measurement accuracy due to external vibration and shaking during measurement.

[0049] Third embodiment

[0050] Reference Figure 5 and Figure 7 In order to adjust and monitor the running status of the production patch in real time, a monitoring mechanism 4 for monitoring whether the film material is deviated is provided at the bottom of the support platform 2. The monitoring mechanism 4 can monitor the running status of the film material in real time. When the film material is deviated, it can be detected by the verticality sensor 44, and then the deviation correction device in the coating machine body 1 can be used to correct the deviation, so as to keep the film material fine-tuned in time and ensure the accuracy of the detection position of the thickness sensor 34. Specifically, it includes a shell 41 fixed to the bottom of the support platform 2, movable cross bars 42 arranged at both ends of the shell 41, and a connecting cross bar 43 arranged between one end of the two movable cross bars 42 and sliding on the inner side of the shell 41. A verticality sensor 44 is provided at one end of the movable cross bar 42 away from the connecting cross bar 43, and thickness sensors 45 are respectively slid at both ends of the connecting cross bar 43, and the tops of the two thickness sensors 45 slide on one end of the two movable cross bars 42 respectively. The thickness sensor 45 performs secondary thickness monitoring of the paste on the film material, so that the staff can find problems in time and make fine adjustments according to the conditions of the film material, thereby reducing the waste of film material and coating paste. A driving component 46 for synchronously driving the two movable cross bars 42 and the connecting cross bar 43 to move is provided on the shell 41, and a linkage component 47 for synchronously driving the verticality sensor 44 to make vertical movement is provided at the bottom of the movable cross bar 42.

[0051] The driving assembly 46 includes a connecting frame 461 which is slidably arranged at both ends of the shell 41 and fixed to the two movable cross bars 42 respectively, and a bidirectional lead screw 462 which is arranged between the two connecting frames 461 and rotatably connected to the shell 41 at both ends through bearing seats, and the two ends of the bidirectional lead screw 462 respectively penetrate the two connecting frames 461 and are threadedly connected thereto, and a rack 463 with one end fixed to the connecting cross bar 43 slides on the inner side of the shell 41, a gear 464 fixed to the middle part of the bidirectional lead screw 462 is meshed and connected to the top of the rack 463, and a servo cylinder 465 for driving the rack 463 to move is detachably installed at the bottom of the shell 41.

[0052] According to the actual film material size, the servo cylinder 465 is started, and the servo cylinder 465 drives the rack 1 463 on its output shaft to move, and the rack 1 463 drives the gear 1 464 meshing with it to rotate, and at the same time, the rack 1 463 pushes the connecting cross bar 43 to move to one side of the shell 41, and the connecting cross bar 43 drives the thickness measuring sensors 2 45 at both ends to move to one side of the shell 41, and the gear 1 464 drives the bidirectional lead screw 462 at its axis to rotate, and the bidirectional lead screw 462 drives the connecting frames 461 at both ends to move to During the middle movement, the two connecting frames 461 respectively drive the movable cross bar 42 at one end thereof to move toward the middle, and the two movable cross bars 42 respectively drive the verticality sensor 44 at one end thereof to move, and adjust the distance between the two verticality sensors 44 to adapt to the actual film material size. At the same time, the two movable cross bars 42 respectively drive the thickness sensor 45 at the other end thereof to move toward the middle, and adjust the distance between the two thickness sensors 45, so as to simultaneously move the verticality sensor 44 and the thickness sensor 45 to the appropriate position to monitor the operating status of the film material.

[0053] In order to make the two verticality sensors 44 move toward the middle while adjusting their vertical heights and adjusting the actual positions of the verticality sensors 44, the operating status of the membrane material can be better monitored to prevent the membrane material from shifting. The linkage assembly 47 includes a limit vertical frame 471 arranged on one side of the verticality sensor 44 and fixed to the movable cross bar 42, and a sliding block 472 slidably arranged on the limit vertical frame 471 and fixed to the verticality sensor 44. A gear 2 473 is provided at the bottom of the sliding block 472. A threaded vertical shaft 474 rotatably connected to the movable cross bar 42 through a bearing is fixed at the axis center of the gear 2 473, and the threaded vertical shaft 474 penetrates the sliding block 472 and is threadedly connected to it. A rack 2 fixed to the housing 41 is meshed on one side of the gear 2 473. When adjusting the distance between the two movable cross bars 42 according to the actual size of the membrane material, the movable cross bar 42 drives gear two 473 to move through the threaded vertical shaft 474, and gear two 473 moves on the fixed rack two, thereby driving gear two 473 to rotate, and gear two 473 drives the threaded vertical shaft 474 to rotate, and the threaded vertical shaft 474 drives the sliding block 472 to move in the vertical direction, and the sliding block 472 drives the verticality sensor 44 on one side thereof to move in the vertical direction, thereby synchronously adjusting the verticality sensor 44 to a suitable monitoring position.

[0054] The present invention is provided with a control system on the supporting platform 2, and the control system includes a programmable PLC, and the programmable PLC is electrically connected to the three servo motors 373 and the servo cylinder 465 respectively, and the programmable PLC is also electrically connected to the thickness sensor 1 34, the thickness sensor 2 45 and the verticality sensor 44, and the programmable PLC is electrically connected to the correction device of the coating machine body 1.

[0055] According to the actual size of the processed film material, the programmable PLC controls three servo motors 373 and servo cylinders 465 respectively. The three servo motors 373 drive the corresponding thickness sensors 34 to move to the appropriate positions respectively. The three thickness sensors 34 measure the paste on the film material at the same time. When the three thickness sensors 34 measure different thicknesses of the paste on the film material, it means that the paste is unevenly coated. The thickness sensor 34 transmits the information to the programmable PLC, and then notifies the staff through the programmable PLC to proceed to the next step.

[0056] The servo cylinder 465 drives the two verticality sensors 44 and the two thickness sensors 45 to move to the appropriate positions through the transmission structure. The verticality sensor 44 monitors the operation process of the film material. When the film material deviates, it can be detected by the verticality sensor 44, and then the deviation correction device in the coating machine body 1 is used to correct the deviation, so that the film material can be fine-tuned in time. The thickness sensor 45 is used to monitor the secondary thickness of the paste on the film material so that the staff can find problems in time and make fine adjustments according to the situation of the film material.

[0057] The control method of the present invention is automatic control through a programmable PLC. The control circuit of the programmable PLC can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
