Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of sheeting machine, concretely relates to intelligent sheeting machine cutter distance detection device. BACKGROUND

[0002] The sheet alkali is the sheet alkali, and the production of the sheet alkali needs to pass through evaporation concentration, solid alkali forming and tablet making multiple links, wherein solid alkali forming and tablet making adopt intelligent automatic sheeting machine to complete.The molten alkali that completes evaporation concentration is sent into the sheeting machine alkali tank and is temporarily stored, and the rotation of the sheeting machine drum makes the molten alkali in the alkali tank adhere to the outer surface of the drum and form solid alkali, and then uses scraper to scrape down the solid alkali from the drum and make sheet alkali.

[0003] The drum bears greater torque in the process of rotating work, and the surface of the drum is the molten alkali of hundreds of degrees, and the inside is cooling liquid, which also makes the drum bear great temperature difference, under the influence of torque and temperature difference, the surface of the drum is easy to deform, concave or bulge, so that the distance between the surface of the drum and the scraper changes, if the distance between the two is too large, the scraper will not be easy to scrape down the solid alkali, and the invalid alkali scraping condition appears, if the distance is too small, the scraper is easy to collide with the surface of the drum, which not only easily leads to the damage of the scraper even the broken knife, but also easily leads to the scratching of the surface of the drum, which undoubtedly will accelerate the corrosion and damage of the drum, and seriously affect the service life of the drum. Therefore, the detection of the distance between the scraper and the drum is very important. CONTENT OF THE UTILITY MODEL

[0004] The utility model intends to provide intelligent sheeting machine cutter distance detection device to automatically detect the distance between the scraper and the drum, ensure that the scraper can effectively scrape alkali, prevent the scraper from scratching and colliding with the drum.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] Intelligent sheeting machine cutter distance detection device, including scraper assembly, detection component and controller,

[0007] The scraper assembly includes scraper, support, knife rest and knife adjusting mechanism, the knife rest is rotatably connected to the support, the scraper is fixedly arranged on the knife rest, a connecting shaft is fixedly arranged on the knife rest, and the connecting shaft is located between the scraper and the support, the knife adjusting mechanism includes a driving shaft and a driving source, one end of the driving shaft is hingedly connected with the connecting shaft, the other end is connected with the driving source, and the driving source is used to drive the driving shaft to move linearly.

[0008] The detection component includes a sensor and a bracket for fixing the sensor, and the sensor is electrically connected to the input end of the controller, and the driving source is electrically connected to the output end of the controller.

[0009] The principle and advantages of the present scheme are that the scraper assembly is used to scrape down the solid alkali in the form of a sheet, and the detection assembly is used to detect the distance between the scraper and the drum in real time. In actual application, the scraper and the sensor are located on the same circumference and are arranged close to each other, and at the same time, the sensor is installed at the front side of the scraper, so that the distance between the sensor and the drum detected by the sensor is equivalent to the distance between the scraper and the drum. When the surface of the drum is concave or bulging, the sensor detects that the distance between the sensor and the drum changes, thereby transmitting a signal to the controller, and the controller controls the driving source to drive the driving shaft to move linearly, and the driving shaft drives the connecting shaft connected thereto to move, since the connecting shaft and the knife holder are fixed together, and the knife holder is rotatably arranged on the support, at this time, the connecting shaft drives the knife holder to rotate on the support, so that the scraper moves in an arc to automatically adjust the distance. When the position of the drum concave or bulging passes the sensor, the sensor detects that the distance between the sensor and the drum changes again, thereby transmitting a signal to the controller, and the controller controls the scraper to move again to adjust the distance between the scraper and the drum.

[0010] In the whole process of detecting and adjusting the distance between the scraper and the drum, since the sensor detects the distance between the scraper and the drum in real time, and the controller adjusts the distance between the scraper and the drum in real time, it is ensured that the scraper can effectively scrape the alkali while effectively preventing the scraper from scratching and colliding with the drum. And since the movement of the driving shaft is converted to a small angle swing of the knife holder through the transmission of the connecting shaft, the scraper can only move a small distance, so that the adjustment of the scraper is better controlled, the accuracy of the adjustment is higher, and the adjustment effect of the position of the scraper is improved. At the same time, since the connecting shaft is located between the scraper and the support, when the driving shaft drives the knife holder to rotate through the connecting shaft, the pushing force can directly act on the knife holder, compared with the traditional driving mode of adopting a lever structure (i.e. the driving force acts on one side of the lever fulcrum, and the driven part is located on the other side of the lever fulcrum), this driving mode can accurately control the knife holder, so as to further improve the adjustment accuracy of the scraper.

[0011] Preferably, as an improvement, the support includes a rotating shaft rotatably arranged, and the sensor is fixedly arranged on the rotating shaft, and the rotating shaft is connected with a power assembly for driving the rotating shaft to rotate.

[0012] Since the sensor is close to the drum and the scraper when working, it is very inconvenient to maintain and replace the sensor. Through the design of the rotating shaft in the above scheme, when it is necessary to maintain or replace the sensor, the rotating shaft can be driven to rotate by the power assembly, so that the rotating shaft drives the sensor to move away from the drum and the scraper, thereby facilitating the maintenance and replacement operation of the sensor.

[0013] Preferably, as an improvement, the support further comprises a bend fixed to the rotating shaft, the bend having a first connecting shaft and a second connecting shaft fixedly connected to the first connecting shaft, the first connecting shaft and the second connecting shaft having an included angle between their axes, the first connecting shaft being fixedly connected to the rotating shaft, and the sensor being fixed to an end of the second connecting shaft away from the first connecting shaft.

[0014] Through the above scheme, the design of the bend can facilitate the installation of other structures, and at the same time, the sensor can better face the surface of the rotating drum, so as to improve the detection accuracy of the tool distance.

[0015] Preferably, as an improvement, the end of the second connecting shaft away from the first connecting shaft is detachably connected with a protective cover, and the sensor is fixed in the protective cover.

[0016] Through the above scheme, the design of the protective cover prevents the alkali dust from falling on the sensor and causing corrosion to the sensor, and has a good protective effect on the sensor, thereby ensuring the detection accuracy of the sensor.

[0017] Preferably, as an improvement, the first connecting shaft, the second connecting shaft and the rotating shaft are all hollow tubular structures, and the wires connected between the sensor and the controller are all installed inside the first connecting shaft, the second connecting shaft and the rotating shaft.

[0018] Through the above scheme, the wires are installed inside the first connecting shaft, the second connecting shaft and the rotating shaft, which can prevent the alkali dust from corroding the wires and make the installation of the device more beautiful.

[0019] Preferably, as an improvement, the scraper assembly and the detection assembly are both provided with multiple groups arranged and distributed and one-to-one corresponding; the power assembly comprises a first motor and a first speed reducer, the input end of the first speed reducer is connected with the output end of the first motor, and the output end of the first speed reducer is connected with the rotating shaft.

[0020] Through the above scheme, since the length of the rotating drum is relatively long, the multiple groups of scraper assemblies and detection assemblies arranged and distributed can work simultaneously to scrape off the solid alkali on the rotating drum, thereby improving the processing efficiency of flake alkali. The first motor serves as a power source to provide power for the rotation of the rotating shaft, and the first speed reducer reduces the output power of the first motor, so that when the sensor needs to be maintained or replaced, the first motor and the first speed reducer jointly act to make the rotating shaft rotate by a small angle to expose the sensor to the outside, which is more convenient for maintenance and replacement operation.

[0021] Preferably, as an improvement, an elastic isolation sleeve is sleeved outside the part where the connecting shaft is hinged to the driving shaft, both ends of the elastic isolation sleeve are fixed to the driving shaft and the connecting shaft respectively; the elastic isolation sleeve is a rubber sleeve or a silica gel sleeve.

[0022] The elastic isolation sleeve is used for isolating and protecting the hinged part between the connecting shaft and the driving shaft, so that the alkaline dust cannot fall on the hinged part to affect the transmission of the structure. The isolation sleeve has elasticity, so that the relative movement of the driving shaft and the connecting shaft is not hindered, and the relative movement of the structure is more adapted. The rubber sleeve or the silica gel sleeve not only has good elasticity, but also can ensure the smooth relative movement between the connecting shaft and the driving shaft. In addition, the rubber sleeve or the silica gel sleeve has good alkali corrosion resistance, so that the service life of the elastic isolation sleeve is longer.

[0023] Preferably, as an improvement, the knife holder comprises a first clamping part rotatably connected to the support and a second clamping part detachably connected to the first clamping part, the first clamping part and the second clamping part have a gap to form a scraper mounting position, the scraper has one end located in the scraper mounting position and the other end extending to the outside of the scraper mounting position and protruding from the first clamping part and the second clamping part; the first clamping part, the second clamping part and the scraper are provided with mounting holes which can be opposite to each other, a fastening bolt is arranged in the mounting holes, and the first clamping part, the second clamping part and the scraper are fixedly connected together by the fastening bolt.

[0024] Through the above scheme, the first clamping part and the second clamping part are used for clamping and mounting the scraper. When it is necessary to adjust the length of the scraper tip protruding from the first clamping part and the second clamping part or replace the scraper, the first clamping part and the second clamping part are only needed to be disassembled, the position of the scraper is adjusted or a new scraper is put in again, and then the first clamping part and the second clamping part are fixed again, so that the adjustment and replacement of the scraper are more convenient. The first clamping part, the second clamping part and the scraper are fixed together by the fastening bolt, so that the fixing effect of the scraper is better.

[0025] Preferably, as an improvement, the rear end of the scraper is provided with an adjusting bolt, the adjusting bolt is threadedly connected with the knife holder, and the mounting hole on the scraper is an elongated hole extending along the length direction of the scraper; the knife holder is further provided with a guide plate, the guide plate is located below the tip of the scraper and close to the scraper.

[0026] Through the above scheme, the adjusting bolt is used for adjusting the length of the scraper protruding to the first clamping part and the second clamping part, or pushing the part originally located in the scraper mounting position out of the first clamping part and the second clamping part after the tip of the scraper is worn or broken, so as to be used as a new scraper tip for scraping the caustic soda. The design of the adjusting bolt makes the adjustment operation of the scraper more convenient. The guide plate is used for guiding the caustic soda scraped by the scraper, so that the caustic soda falls in a fixed direction, and the collection and packaging of the caustic soda are facilitated.

[0027] Preferably, as an improvement, the driving source comprises an electric cylinder, a second speed reducer and a second motor, the input end of the second speed reducer is connected with the output end of the second motor, the output end of the second speed reducer is connected with the input end of the electric cylinder, the output end of the electric cylinder is connected with the driving shaft, and a disc spring is arranged between the electric cylinder and the driving shaft.

[0028] Through the above scheme, through the cooperation of the electric cylinder, the speed reducer and the motor, the stroke of the driving shaft in unit time can be reduced, so that the stroke of the scraper is smaller during each adjustment, the adjustment accuracy of the scraper is improved, and the position control of the scraper is more convenient. In addition, since the material of the rotating drum is generally special and expensive, in order to reduce the maintenance cost, it is necessary to prevent the scraper from scratching the rotating drum as much as possible. In the above scheme, when the scraper is close to or even contacts the surface of the rotating drum, the scraper receives a large reverse thrust from the surface of the rotating drum. At this time, the scraper transmits the reverse thrust to the driving shaft through the connecting shaft, the driving shaft triggers the disc spring to work, so that the disc spring drives the driving shaft to quickly retreat, and then the scraper is quickly reset and away from the rotating drum, so as to prevent or prevent the scraper from scratching the rotating drum.

The mounting hole on the scraper 1 is an elongated hole extending along the length direction of the scraper 1.

[0041] A guide plate 11 is also bolted to the blade holder 3. The guide plate 11 is located at the tip of the scraper 1 (i.e., Figure 1 It is located on the lower side of the upper end shown and close to the scraper 1.

[0042] Combination Figure 2And Figure 3 As shown in the figure, the detection assembly includes a sensor 17 and a bracket for fixing the sensor 17, the sensor 17 is electrically connected to the input end of the controller, and the driving source is electrically connected to the output end of the controller. The bracket includes a rotating shaft 18 arranged in rotation and an elbow 19 fixed to the rotating shaft 18, the elbow 19 has a first connecting shaft 20 and a second connecting shaft 21 fixedly connected with the first connecting shaft 20, the first connecting shaft 20 and the second connecting shaft 21 are integrally formed in this embodiment, the first connecting shaft 20 and the second connecting shaft 21 have an included angle between the axes and are L-shaped, the first connecting shaft 20 is fixedly connected to the rotating shaft 18, and the sensor 17 is fixed to the end of the second connecting shaft 21 away from the first connecting shaft 20, so that the sensor 17 is fixed to the rotating shaft 18. The end of the second connecting shaft 21 away from the first connecting shaft 20 is detachably connected with a protective cover 22, and the sensor 17 is fixed in the protective cover 22. The first connecting shaft 20, the second connecting shaft 21 and the rotating shaft 18 are all hollow tubular structures, and the wires connected between the sensor 17 and the controller are all installed in the interiors of the first connecting shaft 20, the second connecting shaft 21 and the rotating shaft 18. The rotating shaft 18 is connected with a power assembly for driving the rotating shaft 18 to rotate. The power assembly includes a first motor and a first speed reducer, the input end of the first speed reducer is connected with the output end of the first motor, and the output end of the first speed reducer is connected with the rotating shaft 18 to drive the rotating shaft 18 to rotate.

[0043] The sensor 17 in this embodiment uses an eddy current sensor, and the eddy current sensor selected is one that meets the measurement range of 0-20mm, the accuracy of 1-5 microns, and the accuracy does not change between the temperatures of 0-120 degrees Celsius. At the same time, the controller in this embodiment selects an industrial PLC controller, and the PLC controller is provided with a preset value of the distance between the eddy current sensor and the rotating drum. When the measured value of the eddy current sensor is greater than the preset value, the driving source is controlled to drive the scraper to move forward, and when the measured value of the eddy current sensor is less than the preset value, the driving source is controlled to drive the scraper to move backward. In addition, the protective cover 22 is made of alkali-resistant plastic material or other non-conductive or non-magnetic material, so as to play a good protection role while preventing the detection effect of the sensor 17 from being affected.

[0044] The scraper assembly and the detection assembly are both provided with multiple groups of arranged and one-to-one corresponding sensors.

[0045] In the specific implementation of this embodiment, the scraper assembly is used to scrape down the solid alkali in the form of a sheet, and the detection assembly is used for real-time detection of the distance between the scraper 1 and the rotating drum 16. In actual application, referring to Figure 1 , the scraper 1 and the sensor 17 are located on the same circumference and are arranged close to each other, and at the same time, the sensor 17 is installed at the front side of the scraper 1, so that the distance detected by the sensor 17 from the rotating drum 16 is basically equal to the distance between the scraper 1 and the rotating drum 16.

[0046] When the tablet base is made, the drum 16 rotates, and the scraper 1 scrapes the solid base on the drum 16 into tablets, and the sensor 17 detects the distance between itself and the surface of the drum 16 in real time, that is, detects the distance between the scraper 1 and the drum 16 in real time.

[0047] When the surface of the drum 16 is concave or bulging, the sensor 17 detects that the distance between itself and the surface of the drum 16 changes, thereby transmitting a signal to the controller, and the controller controls the driving source to drive the driving shaft 5 to move linearly, and the driving shaft 5 drives the connecting shaft 4 to push the cutter holder 3 to rotate on the support 2, so that the tip of the scraper 1 is close to or away from the drum 16, thereby adjusting the position of the scraper 1, and the adjusted scraper 1 maintains an appropriate distance from the position of the concave or bulging on the drum 16, and then the solid base attached to the surface of the drum 16 is scraped into tablets, and the scraped tablets are guided by the guide plate 11 and are collected uniformly. The elastic isolation sleeve 6 isolates and protects the connection part of the driving shaft 5 and the connecting shaft 4, so as to avoid that the alkali dust falls into the connection part and causes the equipment to be stuck or corroded.

[0048] When the position of the concave or bulging moves away from the sensor 17, the sensor 17 detects that the distance between itself and the surface of the drum 16 changes again, thereby transmitting a signal to the controller, and the controller controls the scraper 1 to move again to adjust the distance between the scraper 1 and the drum 16. It can be understood that through reasonable delay setting, the sensor 17 detects that the distance changes and the controller promotes the scraper 1 to adjust the position after the position of the concave or bulging moves to the position of the scraper 1 to scrape the tablet base.

[0049] When it is necessary to adjust the length of the tip of the scraper 1 protruding from the first clamping part 7 and the second clamping part 8, or when the tip of the scraper 1 is worn or broken, the fastening bolt 9 is loosened, and the bolt 10 is adjusted to push the scraper 1 to move, and the fastening bolt 9 moves in the long hole, so that the part of the scraper 1 between the first clamping part 7 and the second clamping part 8 moves out of the first clamping part 7 and the second clamping part 8, and after the adjustment is completed, the fastening bolt 9 is tightened again.

[0050] When it is necessary to maintain or replace the sensor 17, refer to Figure 3 , through the work of the first motor and the first speed reducer, the rotating shaft 18 rotates, so that the sensor 17 moves away from the drum 16 and the scraper 1, thereby facilitating the maintenance or replacement operation. The protective cover 22 prevents the alkali dust from falling on the sensor 17 and causing corrosion to the sensor 17, and has a good protection effect on the sensor 17, thereby ensuring the detection accuracy of the sensor 17.

[0051] Example 2

[0052] The difference between this embodiment and example 1 is that the structure of the driving source is different, as shown in Figure 4As shown, the drive source in this embodiment includes an electric cylinder 12, a second reducer 13, and a second motor 14. The input end of the second reducer 13 is connected to the output end of the second motor 14, and the output end of the second reducer 13 is connected to the input end of the electric cylinder 12. The output end of the electric cylinder 12 is connected to the drive shaft 5. A disc spring 15 is also provided between the electric cylinder 12 and the drive shaft 5. In practical applications, an elastic isolation sleeve 6 can also be provided at the connection point between the electric cylinder 12 and the drive shaft 5 to isolate and protect the connection point and prevent alkali dust from falling in.

[0053] In this embodiment, the second motor 14 provides initial power, which is then reduced by the second reducer 13 and transmitted to the electric cylinder 12. The electric cylinder 12 converts the rotational power into linear power and drives the drive shaft 5 to move laterally. The cooperation of the second motor 14, the second reducer 13, and the electric cylinder 12 enables the drive source to drive the drive shaft 5 to achieve a small displacement per unit time, thereby improving the movement accuracy of the scraper 1 during blade adjustment, improving the adjustment accuracy of the scraper 1, and making it easier to control the position of the scraper 1. When the scraper 1 is close to or even in contact with the surface of the drum 16, the scraper 1 is subjected to a large counter-force from the surface of the drum 16. At this time, the scraper 1 transmits the counter-force to the drive shaft 5 through the connecting shaft 4. The drive shaft 5 triggers the disc spring 15 to work, causing the disc spring 15 to drive the drive shaft 5 to retract quickly, thereby allowing the scraper 1 to immediately and quickly reset and move away from the drum 16, thus preventing or preventing the scraper 1 from continuing to scratch the drum 16.

[0054] Example 3

[0055] This embodiment is based on the foregoing embodiments, such as... Figure 5 As shown, a push joint is fixedly provided at the rear end of the scraper 1. The push joint includes a first part 23 and a second part 24 that are welded and fixedly connected together. The rear end of the scraper 1 is set perpendicular to the joint of the first part 23 and the second part 24. This ensures that both ends of the scraper 1 have sufficient length to abut against the first part 23 and the second part 24 respectively, thereby ensuring that the push joint can forcefully push the scraper 1. The first part 23 and the second part 24 are symmetrical semi-conical structures, making the push joint as a whole conical shape. A conical sleeve 25 is snapped or welded to one end of the adjusting bolt 10 near the scraper 1. The sleeve 25 is fitted onto the push joint.

[0056] By fitting the sleeve 25 onto the push joint, the adjusting bolt 10 has a larger force area when pushing the scraper 1, making it easier to adjust the scraper 1. Furthermore, since both the sleeve 25 and the push joint are conical, this will not affect the rotation of the adjusting bolt 10.

[0057] In addition, since the push joint is combined by two symmetrical half-cone structures, and the rear end of the scraper 1 is arranged perpendicularly to the joint of the first part 23 and the second part 24, the scraper 1 is conveniently centered and installed when the push joint is installed on the scraper 1, and the first part 23 and the second part 24 can simultaneously push the scraper 1 when the scraper 1 is adjusted, and the sleeve 25 is sleeved outside the push joint, and the first part 23 and the second part 24 are limited, so that the first part 23 and the second part 24 are not easily separated and can strongly push the scraper 1. In addition, the sleeve 25 is used in cooperation with the push joint, so that the contact surface of the two is an inclined surface, so that the scraper 1 can be centered and installed, so that the scraper 1 is always located in the axial direction of the sleeve 25 and the adjusting bolt 10, and it is ensured that the scraper 1 will not be offset.

[0058] The above is only an embodiment of the present application, and the well-known specific technical solutions and / or common knowledge in the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical scheme of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific embodiments in the specification can be used to explain the content of the claims.
