Description

Technical Field

[0001] This invention relates to the field of screen cleaning technology, and in particular to an elastic scraper device and system for automatically clearing blockages in curing agent screens. Background Technology

[0002] Curing agent screens play a crucial role in industrial production. Their core function is to achieve graded screening and impurity removal of curing agent raw materials through precise pore size design, ensuring the uniformity and purity of raw material particles, thereby improving the reactivity and stability of the curing agent product. In practical applications, this technology has been deeply integrated into multiple fields: In the building materials industry, existing screening devices use double-layer screens (180 mesh and 240 mesh stainless steel) for gradient filtration of curing agent raw materials, combined with cutters to break up clumps, increasing the compressive strength of highway base materials by more than 30%; in the electronic packaging industry, epoxy curing agent production uses a centrifugal motor-driven double-layer screen system, combined with an airflow anti-clogging mechanism formed by steam exhaust outlets, ensuring the uniform curing of integrated circuit packaging materials, with product temperature resistance reaching 180℃; in the environmental engineering field, new vibrating screens, driven by servo motors, feature a 180° screen rotation design, enabling rapid cleaning of curing agent residues in silty soil treatment, improving the construction efficiency of canal seepage prevention projects by 45%. These innovative applications not only optimize the production quality of curing agents but also promote the upgrading of material performance in industries such as civil engineering and electronics manufacturing.

[0003] Existing curing agent screens are prone to clogging during use due to various factors. Curing agent raw materials often contain fine powder, fibers, or agglomerated particles. These substances are easily stuck into the screen holes during screening, especially when the raw material has high moisture content, the adhesion between particles is enhanced, making it easier to form agglomerates that clog the screen holes. To address the clogging problem, a graded treatment strategy can now be adopted, and particles can be dislodged by mechanical vibration (such as a high-frequency vibrator) or airflow pulse (compressed air backflushing).

[0004] While the corresponding mechanisms can prevent filtered impurities from getting stuck in the screen holes, larger particles that are bounced off still remain on the screen surface. These impurities will then get stuck again in the screen holes during subsequent filtration. As more and more large particles are blocked, the screen becomes more prone to clogging. Even if the vibration mechanism continuously ejects the impurities stuck in the screen holes, the excessive amount of impurities still cannot prevent clogging during subsequent filtration. Therefore, most existing screen filtration mechanisms also include scrapers to remove the ejected impurities from the screen surface. However, existing anti-clogging scraper mechanisms usually require stopping the filtration operation before they can be used to avoid scraping away the original material while removing impurities from the screen surface. This makes it impossible to perform anti-clogging and impurity removal operations on the screen without interfering with normal filtration. Summary of the Invention

[0005] The purpose of this invention is to provide an elastic scraper device and system for automatically clearing blockages from a curing agent screen. The device can clean impurities blocked on the screen surface without affecting normal filtration, thus avoiding blockages caused by excessive impurities on the screen surface.

The vibrator is installed on the side of the loading frame close to the screen frame. The shielding component is disposed inside the loading frame and is located at the top of the pusher frame to shield falling materials. The push-out component is disposed inside the loading frame to drive the pusher frame.

[0008] The shielding component includes a shielding cloth, a take-up roller, and a torsion spring. Each pusher is provided with the shielding cloth. Two take-up rollers are used to store the shielding cloth on both sides of the frame. The two take-up rollers are rotatably mounted on both sides of the loading frame. Each take-up roller is provided with a torsion spring on both sides.

[0009] The ejection component includes a guide rail frame, a rotary push rod, a driving component, and a synchronous drive component. Two guide rail frames are fixedly installed on the back side of each ejection frame. A rotary push rod is provided on each guide rail frame and is rotatably installed inside the loading frame. The driving component is connected to the rotary push rod, and the synchronous drive component is connected to the loading frame. The synchronous drive component and the driving component synchronously drive the two rotary push rods located on the same side.

[0010] The driving component includes a worm gear and a driving worm, and the worm gear is fixedly mounted on each of the rotary push rods; the driving worm is connected to the worm gear and is rotatably installed in the loading frame.

[0011] The synchronous drive component includes a connecting gear, a main shaft, a main gear, and a main motor. Each driving worm is fixedly fitted with the connecting gear. Two main shafts are rotatably mounted on both sides of the loading frame. Each main shaft is fixedly fitted with a main gear, which meshes with two connecting gears located on the same side. Two main motors are mounted on both sides of the loading frame, and the two main motors drive the main shafts on both sides respectively.

[0012] The auxiliary components include a lower spring scraper, an ejector spring, a rotating latch, an upper pusher, and a limiting member. The lower spring scraper is slidably mounted on each of the pushers. The ejector spring is connected to the lower spring scraper and the pusher on both sides, respectively. The rotating latch is rotatably mounted inside the pusher. The upper pusher is connected to the loading frame and is used to push the lower spring scraper at a designated position to move upward. The limiting member is connected to the pusher and is used to limit the rotating latch.

[0013] The upper lifting component includes an upper lifting plate frame and a screw lifting mechanism. The two upper lifting plates are slidably installed on both sides of the loading frame. The two sets of screw lifting mechanisms are respectively arranged on both sides of the loading frame, and the two sets of screw lifting mechanisms drive the upper lifting plates on both sides respectively.

[0014] The limiting component includes a magnetic side plate, an adsorption top block, a side shifting frame, a locking spring frame, and a top spring. The magnetic side plate is fixedly installed on one side of the rotating clamp; the adsorption top block is fixedly installed on the side of the push frame near the magnetic side plate; the side shifting frame is slidably installed inside the push frame; the locking spring frame is slidably installed above the side shifting frame; and the two sides of the top spring are respectively connected to the locking spring frame and the side shifting frame.

[0017] This invention discloses an elastic scraper device and system for automatically clearing blockages in a curing agent screen. In actual operation, the screen frame mounted on the loading frame completes the screening and filtration of the curing agent raw material. After a period of filtration, the pusher frame on the corresponding side of the loading frame slides under the action of the pusher component. During the sliding process, the shielding component shields the top of the sliding area of ​​the pusher frame, preventing material falling from the top of the processing box from entering the corresponding pusher frame's movement path. When the pusher frame moves to the middle of the loading frame, the corresponding scraper mechanism mounted on the pusher frame, in conjunction with the reverse movement of the pusher frame, cleans the impurities blocked on the previous movement path. The cleaned impurities fall into the discharge trough on a designated side of the loading frame. After one side of the pusher frame completes cleaning, the other side can clean the other side of the screen frame. This achieves the ability to clean impurities blocked on the screen surface without affecting normal filtration, preventing blockages caused by excessive impurities on the screen surface.

Detailed Implementation

[0030] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0031] In the description of this invention, it should be understood that "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Please see Figures 1 to 10This invention provides an elastic scraper device and system for automatically clearing blockages in a curing agent screen: It includes a processing box 101, a loading frame 102, a screen frame 103, and auxiliary components. The auxiliary components include a closed base plate 104, a pushing frame 105, a guide pulley 106, a vibrator 107, a shielding component, and a pushing component. The shielding component includes a shielding cloth 201, a winding roller 202, and a torsion spring 203. The pushing component includes a guide rail frame 301, a rotary push rod 302, a driving component, and a synchronous driving component. The driving component includes a worm gear 401 and a driving worm 402. The synchronous driving component includes a connecting gear 501, a main rotating shaft 502, a main rotating gear 503, and a main rotating motor 504. This solution addresses the issue that while the corresponding mechanism can prevent filtered impurities from getting stuck, it also solves the problem of blockages. While larger particles are ejected from the screen, they remain on the screen surface. These impurities will then re-enter the screen during subsequent filtration. As more and more large particles are trapped, the screen becomes more prone to clogging. Even with vibration mechanisms constantly ejecting the impurities from the screen, the excessive amount of impurities cannot prevent clogging during subsequent filtration. Therefore, most existing screen filtration mechanisms also include scrapers to remove the ejected impurities from the screen surface. However, existing anti-clogging scraper mechanisms usually require stopping the filtration operation to avoid scraping away the original material along with the impurities on the screen surface. This makes it impossible to perform anti-clogging and impurity removal operations on the screen without interfering with normal filtration.

[0033] Furthermore, the loading frame 102 is disposed inside the processing box 101, the screen frame 103 is disposed on the loading frame 102, the closed bottom plate 104 is disposed at the bottom of the loading frame 102, the two push frames 105 are respectively slidably mounted on the left and right sides of the loading frame 102, each push frame 105 is provided with guide pulleys 106 on both sides, the two push frames 105 are located on the upper side of the screen frame 103, the vibrator 107 is installed on the side of the loading frame 102 near the screen frame 103, the shielding member is disposed inside the loading frame 102, the shielding member is located at the top of the push frame 105, and is used to shield the falling material, and the pushing member is disposed inside the loading frame 102, and is used to drive the push frame 105.

[0034] Specifically, the processing box 101 is the main storage structure for screening curing agents. The processing box 101 has an internal loading slot for installing the loading rack 102. The loading rack 102 can be installed in the processing box 101 by setting a corresponding installation structure, or it can be directly fixed in the processing box 101 by bolts, so that users can install the loading rack 102 according to actual operation and usage requirements.

[0035] The loading frame 102 is fixedly mounted with a screen frame 103 by bolts. The screen frame 103 is provided with a plurality of small screen holes, which can achieve filtration. Two sets of vibrators 107 are provided on the loading frame 102. The two sets of vibrators 107 can drive the screen frame 103 to vibrate continuously in small amplitudes to prevent impurities from getting stuck in the screen holes of the screen frame 103. At the same time, the continuous small amplitude vibration of the screen frame 103 can also improve the filtration efficiency.

[0036] Two pusher frames 105 are respectively provided on both sides of the loading frame 102. At the same time, corresponding material leakage grooves are also provided on both sides of the loading frame 102. The bottom of the material leakage groove is open. The bottom opening of the material leakage groove on both sides can be sealed by bolts using the closed bottom plate 104.

[0037] When the processing box 101 is provided with a corresponding discharge channel at its bottom, the openings of the material leakage troughs on both sides of the loading frame 102 can be opened. In this way, the impurities that are swept into the material leakage troughs will be discharged through the discharge channel of the processing box 101. If the processing box 101 is not provided with a discharge channel, the material leakage troughs on both sides of the loading frame 102 can be covered by the installation of the closed bottom plate 104, so that the swept impurities fall directly into the material leakage troughs, thereby achieving the collection of swept impurities. In this way, the user can make flexible adjustments according to the actual type and specific structure of the processing box 101. However, since the space of the material leakage troughs on both sides of the loading frame 102 is limited, if only the material leakage troughs on both sides of the loading frame 102 are used to collect impurities, after working for a period of time, the operator needs to remove the entire loading frame 102 from the processing box 101 to clean the impurities inside the material leakage troughs.

[0038] The pusher frame 105 is provided with corresponding guide pulleys 106 on both sides. The guide pulleys 106 make the pusher frame 105 move more smoothly on the loading frame 102. The loading frame 102 is also provided with corresponding guide slots. Since the guide pulleys 106 cooperate with the roller grooves inside the side wall of the loading frame 102, the guide slot size is small. At the same time, a corresponding baffle is provided on the top of the loading frame 102 to prevent materials falling from the top of the processing box 101 from entering the roller grooves through the guide slots.

[0039] In actual operation, the screen frame 103 set on the loading frame 102 completes the screening and filtration of the curing agent raw material. After filtration for a period of time, the pusher frame 105 on the corresponding side of the loading frame 102 can slide under the operation of the pusher member. During the sliding of the pusher frame 105, the shielding member can shield the top of the sliding area of ​​the pusher frame 105, so that the material falling from the top of the processing box 101 will not fall into the moving path of the corresponding pusher frame 105. When the pusher frame 105 moves to the middle of the loading frame 102... By using the corresponding scraper mechanism on the pusher 105 in conjunction with the reverse movement of the pusher 105, impurities blocked on the previous movement path can be cleaned. The cleaned impurities will fall into the material leakage trough on the designated side of the loading frame 102. After the pusher 105 on one side has finished cleaning, the pusher 105 on the other side can clean the other side of the screen frame 103. This allows the impurities blocked on the screen surface to be cleaned without affecting the normal filtration operation, thus avoiding blockage caused by a large number of impurities on the screen surface.

[0040] Furthermore, each of the pusher frames 105 is provided with a shielding cloth 201; two take-up rollers 202 are respectively used to store the shielding cloths 201 on both sides, and the two take-up rollers 202 are respectively rotatably installed on both sides of the loading frame 102; each of the take-up rollers 202 is provided with a torsion spring 203 on both sides.

[0041] In this embodiment, the front sides of the two push frames 105 face each other, and the back side of the push frame 105 is fixed with the shielding cloth 201. The shielding cloth 201 on each side is wound up and reset by the take-up roller 202. The take-up roller 202 is provided with torsion springs 203 on both sides. The torsion springs 203 can apply a corresponding torque to the take-up roller 202, so that when the push frame 105 moves, the shielding cloth 201 wound on the take-up roller 202 can be continuously stretched and laid out. When the push frame 105 resets, the shielding cloth 201 can also be reset. The shielding cloth 201 is wound up by the take-up roller 202, and the torque applied by the torsion spring 203 can also ensure the stability of the shape of the shielding cloth 201 after stretching, avoiding large deformation of the shielding cloth 201 in the spread state due to physical falling impact. At the same time, in actual design, the spread shielding cloth 201 and the top of the pusher frame 105 can form a small angle slope, which can reduce the impact of falling materials on the shielding cloth 201, and also allow the materials on the shielding cloth 201 to roll to the other side after falling onto the cloth surface, avoiding excessive accumulation of materials on the surface of the shielding cloth 201.

[0042] Furthermore, two guide rail frames 301 are fixedly installed on the back side of each pusher frame 105; each guide rail frame 301 is provided with a rotary push rod 302, which is rotatably installed inside the loading frame 102; the driving component is connected to the rotary push rod 302, and the synchronous drive component is connected to the loading frame 102, so that the two rotary push rods 302 located on the same side are synchronously driven by the synchronous drive component and the driving component.

[0043] Furthermore, each of the rotary push rods 302 is fixedly fitted with the fitted worm gear 401; the driving worm 402 is connected to the fitted worm gear 401 and is rotatably installed in the loading frame 102.

[0044] Furthermore, each of the driving worm gears 402 is fixedly fitted with the connecting gear 501; the two main rotating shafts 502 are respectively rotatably mounted on both sides of the loading frame 102; each of the main rotating shafts 502 is fixedly fitted with the main rotating gear 503, and the main rotating gear 503 meshes with the two connecting gears 501 located on the same side; the two main rotating motors 504 are respectively mounted on both sides of the loading frame 102, and the two main rotating motors 504 drive the main rotating shafts 502 on both sides respectively.

[0045] In this embodiment, the pusher 105 is fixed with guide rails 301 on both the upper and lower sides of its back. Each guide rail 301 is connected to one end of a top or bottom rotating push rod 302. The rotating push rod 302 engages with the guide groove of the guide rail 301 via a protruding frustum, allowing it to rotate on the guide rail 301 and move along its guide groove. The two rotating push rods 302 engaging with the same pusher 105 are arranged crosswise. By synchronously driving the two guide rails 301 on the back of the pusher 105, the designated pusher 105 can be driven. When the rotating push rod 302 rotates, the end connected to the guide rail 301... The pusher 105, on which the guide rail frame 301 is mounted, will be continuously squeezed, causing the pusher 105 to move on the loading frame 102. In actual operation, when the rotary push rod 302 rotates forward under the drive of the sleeved worm gear 401, the other end of the rotary push rod 302 will squeeze the guide rail frame 301, so that the end of the rotary push rod 302 connected to the guide rail frame 301 can push out the pusher 105, which is fixed to the guide rail frame 301, by continuously sliding on the guide groove. When the rotary push rod 302 rotates in the opposite direction under the drive of the sleeved worm gear 401, the other end of the rotary push rod 302 will cooperate with the guide rail frame 301 to pull back the pushed pusher 105 after it has been pushed out, thereby driving the pusher 105 to retract, so as to realize the back-and-forth drive of the pusher 105.

[0046] By using two alternating push rods 302 in conjunction with the guide rail frame 301 to drive the push frame 105, the overall size of the drive structure can be reduced as much as possible while ensuring the stable movement of the push frame 105, thus avoiding the drive structure affecting the normal filtration and screening operation of the entire equipment.

[0047] The push rod 302 is rotatably connected to the loading frame 102, and a worm gear 401 is fixed on one side. Each worm gear 401 is equipped with a corresponding driving worm 402 for driving. The driving worm 402 has a corresponding thread on a section of the rod that cooperates with the worm gear 401. At the same time, a connecting gear 501 is fixedly sleeved at the end of each driving worm 402. The two connecting gears 501 on the same side mesh with the main rotating gear 503 on the corresponding main rotating shaft 502. Each main rotating shaft 502 is driven by a corresponding main rotating motor 504. The push frames 105 on both sides are driven by independent driving structures on both sides. Then, the control module is set to realize the alternating control of the main rotating motors 504 on both sides, so that the cleaning of the entire screen can be carried out normally.

[0048] Since the two rotary push rods 302 on the same side rotate in opposite directions when driven by the same push frame 105, while the driving worm gears 402 on both sides of the above-mentioned synchronous transmission mechanism rotate in the same direction, the thread direction of the rods that cooperate with the worm wheel 401 on the two driving worm gears 402 is set in opposite directions, so as to ensure that the two rotary push rods 302 on the same side can rotate synchronously in opposite directions.

[0049] Preferably, the auxiliary components provided by the present invention further include a lower spring scraper 601, an ejector spring 602, a rotating clamp 603, an upper lifting component, and a limiting component. The upper lifting component includes an upper lifting plate frame 701 and a lead screw lifting mechanism 702. The limiting component includes a magnetic side plate 801, an adsorption top block 802, a side shift frame 803, an upper locking spring frame 804, and an upper lifting spring 805. The limiting component also includes a side lifting spring 806, a magnetic support plate 807, and an adsorption magnet 808.

[0050] Furthermore, each of the pusher frames 105 is slidably mounted with a lower spring scraper 601; the two sides of the ejector spring 602 are respectively connected to the lower spring scraper 601 and the pusher frame 105; the rotating clamp 603 is rotatably mounted inside the pusher frame 105; the upper pusher is connected to the loading frame 102 and is used to push the lower spring scraper 601 at a designated position upward; the limiting member is connected to the pusher frame 105 and is used to limit the rotating clamp 603.

[0051] Furthermore, the two upper top plate frames 701 are slidably installed on both sides of the loading frame 102; the two sets of screw-driven upper lifting mechanisms 702 are respectively arranged on both sides of the loading frame 102, and the two sets of screw-driven upper lifting mechanisms 702 drive the upper top plate frames 701 on both sides respectively.

[0052] In this embodiment, during use, the lower spring scraper 601 matches the adapter groove provided on the pusher frame 105. Multiple ejector springs 602 are provided on the top plate of the lower spring scraper 601. Driven by the pusher frame 105, the lower spring scraper 601 can scrape and clean the surface of the screen frame 103. During normal operation, both the pusher frame 105 and the lower spring scraper 601 are located inside the side wall of the loading frame 102. When cleaning is required, the pusher frame 105 will move the lower spring scraper 601. The pusher frame 105 moves out of the side wall of the loading frame 102 mainly by stretching the shield... The baffle 201 is used to cover a designated area, not to clean or scrape off impurities on the screen surface within that area. Therefore, before the pusher 105 moves out from the side wall of the loading frame 102, the lower spring scraper 601 needs to move upward. Then, with the help of the rotating latch 603 and the limiting member, the lower spring scraper 601 is kept in an upward and retracted state until the pusher 105 moves to the middle of the loading frame 102. During the movement of the pusher 105, the area covered by the baffle 201 can still be filtered normally by the vibrator 107, preventing the scraping off of some qualified materials during the subsequent cleaning of impurities.

[0053] The lower scraper 601 moves upward via the upper top plate frame 701 and the lead screw lifting mechanism 702. The upper top plate frame 701 is threadedly connected to the drive lead screw of the lead screw lifting mechanism 702. When the motor of the lead screw lifting mechanism 702 drives the corresponding drive lead screw to rotate, the upper top plate frame 701 can move. The upward movement of the upper top plate frame 701 pushes the lower scraper 601 into the pusher frame 105, realizing the upward movement and retraction of the lower scraper 601. It should be noted that the upper top plate frame 701 will quickly reset after pushing the lower scraper 601, so that the impurities scraped off by the lower scraper 601 can fall smoothly into the discharge trough, and at the same time, it will not interfere with the subsequent reset of the lower scraper 601 and the pusher frame 105.

[0054] Furthermore, the magnetic side plate 801 is fixedly installed on one side of the rotating clamp 603; the adsorption top block 802 is fixedly installed on the side of the pusher 105 near the magnetic side plate 801; the side shifter 803 is slidably installed inside the pusher 105; the locking spring frame 804 is slidably installed above the side shifter 803; and the two sides of the top spring 805 are respectively connected to the locking spring frame 804 and the side shifter 803.

[0055] Furthermore, the two sides of the side top spring 806 are respectively connected to the side shift frame 803 and the push frame 105; the magnetic support plate 807 is fixedly installed on one side of the side shift frame 803; the adsorption magnetic block 808 is fixedly installed inside the loading frame 102, and the adsorption magnetic block 808 is located on the upper side of the screen frame.

[0056] In this embodiment, the rotating clamp 603 is rotatably mounted on the side wall of the pusher 105. The rotating clamp 603 is "L" shaped. When the lower spring scraper 601 moves up above the pusher 105, the top plate of the pusher 105 will press against one side plate of the rotating clamp 603, causing the rotating clamp 603 to rotate. When the lower spring scraper 601 moves to the upper limit position, the other side plate of the rotated rotating clamp 603 will lock and limit the lower spring scraper 601, preventing it from sliding down.

[0057] The rotating clamp 603 is fixed with a magnetic side plate 801. The magnetic side plate 801 is provided with an adsorption area. Each magnetic side plate 801 is provided with an adsorption top block 802 for cooperation. When the rotating clamp 603 is not squeezed or subjected to any external force, the magnetic side plate 801 will be adsorbed by the adsorption top block 802. When the lower spring scraper 601 moves upward and squeezes the rotating clamp 603 to rotate, the magnetic side plate 801 provided on the rotating clamp 603 will detach from the adsorption top block 802.

[0058] The bottom of the magnetic side plate 801 is also provided with the locking spring frame 804 for cooperation. The locking spring frame 804 is slidably disposed on the top of the side shift frame 803. The bottom of the locking spring frame 804 is provided with the top spring 805. The side shift frame 803 is slidably disposed inside the push frame 105. The side plate of the side shift frame 803 is fixed with two magnetic support plates 807. At the same time, the side spring 806 is also provided between the side of the side shift frame 803 and the inner groove side wall of the push frame 105. The adsorption magnetic block 808 is embedded in the middle side wall of the loading frame 102.

[0059] When the rotating latch 603 rotates due to the upward movement of the lower spring scraper 601, the magnetic side plate 801 on the rotating latch 603 will press against the top protrusion of the locking spring holder 804. After being pressed by the magnetic side plate 801, the locking spring holder 804 will move downward a certain distance. When the magnetic side plate 801 follows the rotating latch 603 and completely flips over, the locking spring holder 804 will move upward under the action of the upper spring 805. Then, through the cooperation between the protrusion on the top of the locking spring holder 804 and the magnetic side plate 801, the rotating latch 603 will be limited, preventing the rotating latch 603 from rotating. At this time, the corresponding plate of the rotating latch 603 will lock and limit the position of the top plate of the lower spring scraper 601.

[0060] When the pusher 105 moves the retracted lower scraper 601 to the middle of the loading frame 102, the magnetic support plate 807 on the side plate of the side shifter 803 will cooperate with the adsorption magnet 808 embedded in the inner wall of the loading frame 102. The adsorption magnet 808 will attract the magnetic support plate 807 to slide, thereby driving the side shifter 803 to move. After the side shifter 803 moves, the magnetic support plate 807 on the rotating clamp 603 will move. The suction side plate 801 is no longer limited by the locking spring frame 804. At the same time, the compressed ejector spring 602 will also drive the lower spring scraper 601 to move down. As the lower spring scraper 601 moves down, the rotating latch 603 will rotate and reset. Then, the magnetic suction side plate 801 and the suction top block 802 will cooperate to complete the reset. The ejected lower spring scraper 601 will then follow the reverse movement of the pusher frame 105 to clean the designated half area of ​​the screen.
