Description

Technical Field

[0001] The invention belongs to the technical field of automobile molds, and in particular relates to a mold scraping self-correcting device and a use method thereof. Background Art

[0002] In the process of implementing the present invention, the inventors discovered that the prior art has at least the following problems:

[0003] Mold scraping equipment is a kind of scraping equipment specially used for discharge trough. The equipment is mainly composed of scrapers, chains, drive devices and other components. The scrapers are driven by the chains to make continuous linear motion in the trough, thereby scraping off the mud and sand at the bottom of the trough and discharging it out of the trough.

[0004] Normally, there are two chains, which are driven by the same drive roller to achieve synchronous operation. The scraper is placed horizontally between the two chains. A retractable structure is usually adopted between the scraper and the chain. This retractable structure is generally a spring sleeve structure. The spring sleeve is generally composed of an inner tube, an outer tube and a spring. The inner tube and the outer tube are fixed on the scraper and the chain respectively, and the inner tube is placed in the outer tube at the same time and the two are connected by a spring. On the basis of this retractable structure, when the scraper contacts the bottom of the trough, it will be pushed by the spring, which can increase the contact force between the scraper and the bottom of the trough and improve the scraping effect.

[0005] When the scraper is not in contact with the bottom of the trough, the scraper will return to its original position under the action of the spring. However, due to the sliding wear between the inner tube and the outer tube and the loss of the spring, the sliding between the inner tube and the outer tube is stuck, which causes the entire scraper to appear high at one end and low at the other end. Not only is the contact with the bottom of the trough poor, but the forces at both ends during the scraping process are different, which will cause the entire scraper to bend and be damaged over time.

[0006] During this process, monitoring sensors are generally installed on both sides of the scraper. The distance between the sensors on both sides and the scraper end is used to determine whether the scraper is tilted, or the time difference between the two ends of the scraper passing through the sensor is used to determine whether the scraper is tilted or bent. When a tilt state is detected, an alarm is triggered. At this time, the management personnel need to stop the machine and adjust or repair and replace the scraper. This process is time-consuming and reduces the operating efficiency of the equipment.

[0007] CN207271519U - A self-adhesive waterproof roll material scraping device with automatic edge finding, discloses a self-adhesive waterproof roll material scraping device with automatic edge finding, the device is used to scrape glue on the back of the roll material, the roll material is driven to move by a guide roller, the device includes a gluing mold, a glue supply system, a movable frame, a guide rail, a correction hydraulic mechanism and a correction detector, the glue supply system, the gluing mold and the correction detector are all located on the movable frame, and cannot solve the above technical problems. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide a mold scraper self-correcting device and a method of using the same. Through the design of the self-correcting device, the inclination problem of the scraper can be automatically detected and corrected without manual intervention; the equipment downtime caused by the inclination of the scraper is greatly reduced, and the operating efficiency and scraping effect of the equipment are improved.

[0009] In order to solve the above technical problems, the technical solution adopted by the present invention is: a mold scraper self-correcting device and a method of using the same, having:

[0010] discharge chute;

[0011] A chain is rotatably mounted in the discharge chute;

[0012] Scrapers: a series of scrapers are provided on the chain, and the scrapers can scrape away the waste in the discharge chute;

[0013] The deviation-correcting component is installed on the trough wall of the discharge trough.

[0014] The correction component has:

[0015] There are two fixing seats, which are installed on the groove wall;

[0016] A bare rod, connecting two fixed seats;

[0017] A slider, slidably mounted on the polished rod;

[0018] A return mechanism is installed on the polished rod, and the return mechanism can drive the slider to return;

[0019] a baffle, slidably mounted on the slider, the baffle being capable of pushing the scraper;

[0020] The baffle driving mechanism can drive the baffle to slide.

[0021] The baffle driving mechanism includes a driving gear and a longitudinal rack. The driving gear is rotatably mounted on the slider. The baffle is provided with a longitudinal rack that matches the driving gear.

[0022] A synchronization mechanism is also provided, which includes a transverse rack and a linkage gear; the first end of the transverse rack is fixed on a fixed seat; the linkage gear is rotatably mounted on a slider; one side of the linkage gear is engaged with the driving gear, and the other side is engaged with the transverse rack.

[0023] The return mechanism is a spring, which is sleeved on the polished rod. The first end of the spring contacts the slider, and the second end of the spring contacts a fixed seat.

[0024] The upper surface of the slider is integrally formed with two upper side plates spaced opposite to each other. The transverse rack is arranged between the two upper side plates with its tooth surface facing upward. At the same time, the transverse rack is arranged without contact with the upper side plates and the slider.

[0025] The rear end of the transverse rack is fixedly connected to the fixing seat, and the extending direction of the transverse rack is parallel to the polished rod.

[0026] The baffle is arranged above the transverse rack, the bottom end of the baffle is spaced from the transverse teeth, the upper end of the baffle extends to the upper position of the upper side plate, and the scraper can push the baffle to slide after contacting the baffle.

[0027] The above-mentioned method of using the mold scraper self-correcting device is that when the baffle is pushed forward by the scraper, the slider is also pushed forward. At this time, a relative displacement effect is generated between the slider and the transverse rack, and then the linkage gear produces a relative meshing and rolling motion effect relative to the transverse rack, that is, the linkage gear rolls forward relative to the transverse rack, and the linkage gear drives the driving gear to rotate in the opposite direction, and the driving gear drives the longitudinal rack to slide upward along the slide groove. At this time, since the scraper is attached to the baffle, the upward sliding longitudinal rack contacts the scraper from bottom to top when it moves a certain distance, and a lifting effect is generated on the scraper. This lifting effect not only allows the scraper to separate from the baffle, but also plays a role in resetting the scraper, thereby achieving the effect of correction. After the scraper separates from the baffle, under the action of the spring, the slider is reset to its original position, and the longitudinal rack is also restored to its original position under the reverse motion.

[0028] One of the above-mentioned technical solutions has the following advantages or beneficial effects: Through the design of a self-correcting device, the present invention can automatically detect and correct the tilt of the scraper without manual intervention. This greatly reduces equipment downtime caused by scraper tilt, improves equipment operating efficiency and scraping effect; the self-correcting device detects the tilt of the scraper in real time through the sliding of the slider on the polished rod and the elastic action of the spring. The automatic correction of scraper tilt is achieved by the precise transmission coordination of the transverse rack, longitudinal rack, drive gear, and linkage gear; due to the presence of the self-correcting device, the tilt problem of the scraper is effectively solved, thereby reducing the repair and replacement costs caused by scraper bending and damage.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0036] Example 1

[0037] See also Figures 1 to 5 , a mold scraper self-correcting device and its use method, comprising: a discharge trough; a chain, rotatably installed in the discharge trough; a scraper 12, a series of scrapers 12 are provided on the chain, and the scraper 12 can scrape the waste in the discharge trough; wherein the scraper 12 is driven by the chain to make continuous linear motion in the trough, thereby scraping off the mud and sand at the bottom of the trough and discharging it out of the trough. The correction component 1 is installed on the trough wall of the discharge trough. Through the design of the self-correcting device, the present invention can automatically detect and correct the tilt problem of the scraper 12 without manual intervention. This greatly reduces the equipment downtime caused by the tilt of the scraper 12, improves the operating efficiency of the equipment and the scraping effect; the self-correcting device detects the tilt state of the scraper 12 in real time through the sliding of the slider 4 on the light rod 3 and the elastic action of the spring 5. By utilizing the precise transmission coordination of the transverse rack 7, the longitudinal rack 9, the driving gear 10 and the linkage gear 11, the automatic correction of the inclination of the scraper 12 is achieved; due to the existence of the self-correcting device, the inclination problem of the scraper 12 is effectively solved, thereby reducing the maintenance and replacement costs caused by bending and damage of the scraper 12.

[0038] The correction component 1 comprises: a fixed seat 2, of which there are two, and the two fixed seats 2 are installed on the groove wall; a polished rod 3, connecting the two fixed seats 2; a slider 4, slidingly mounted on the polished rod 3; a return mechanism, mounted on the polished rod 3, and the return mechanism can drive the slider 4 to return; a baffle 8, slidingly mounted on the slider 4, and the baffle 8 can push the scraper 12; a baffle 8 driving mechanism, which can drive the baffle 8 to slide.

[0039] The driving mechanism of the baffle 8 includes a driving gear 10 and a longitudinal rack 9. The driving gear 10 is rotatably mounted on the slider 4. The baffle 8 is provided with a longitudinal rack 9 adapted to the driving gear 10.

[0040] A synchronization mechanism is also provided, comprising a transverse rack 7 and a linkage gear 11. The first end of the transverse rack 7 is fixed to the fixed seat 2. The linkage gear 11 is rotatably mounted on the slider 4. One side of the linkage gear 11 meshes with the drive gear 10 and the other side meshes with the transverse rack 7. The return mechanism is a spring 5, which is mounted on the polished rod 3. The first end of the spring 5 contacts the slider 4, and the second end of the spring 5 contacts one of the fixed seats 2.

[0041] The upper surface of the slider 4 is integrally formed with two upper side plates 6 spaced apart and facing each other. A transverse rack 7 is disposed between the two upper side plates 6 with its teeth facing upward, and the transverse rack 7 is disposed so as not to contact the upper side plates 6 or the slider 4. The slider 4 is slidably mounted on the polished rod 3, thereby enabling the slider 4 to achieve linear motion along the polished rod 3. A spring 5 is mounted on the polished rod 3, with the front and rear ends of the spring 5 elastically contacting the adjacent fixed seat 2 and the slider 4, respectively. Therefore, when the slider 4 is subjected to an external force and slides forward, the slider 4 can compress the spring 5. When the external force acting on the slider 4 is eliminated, the slider 4 can slide back to its original position under the rebound action of the spring 5. In this embodiment, the forward direction is the direction of movement of the device. The upper surface of the slider 4 is a planar structure, and two slider upper side plates 6 are integrally formed on the upper surface of the slider 4, which are spaced apart and opposite to each other. The transverse rack 7 is arranged with the tooth surface facing upward between the slider upper side plates 6, and the transverse rack 7 is arranged without contact with the slider upper side plates 6 and the slider 4; the rear end of the transverse rack 7 is fixedly connected to the fixed seat 2 located on the rear side, and the extension direction of the transverse rack 7 is parallel to the light rod 4.

[0042] The rear end of the transverse rack 7 is fixedly connected with the fixed seat 2, and the extension direction of the transverse rack 7 is parallel to the light pole 3. The baffle 8 is arranged at the upper position of the transverse rack 7, the bottom end of the baffle 8 is spaced from the transverse rack 7, and the upper end of the baffle 8 extends to the upper position of the upper side plate 6. The scraper 12 can push the baffle 8 to slide after contacting the baffle 8. A vertical sliding groove is arranged on the rear surface of the baffle 8 with the longitudinal sliding rack 9 arranged in the sliding groove. The longitudinal sliding rack 9 is in transmission engagement with the rack drive gear 10 at the rear side of the longitudinal sliding rack 9. The rack drive gear 10 is in transmission engagement with the linkage gear 11 below the rear side of the rack drive gear 10. The linkage gear 11 is in transmission engagement with the transverse rack 7 below the linkage gear 11. The longitudinal sliding rack 9 and the rack drive gear 10 are arranged at the position between the sliding blocks and the upper side plates 6. The longitudinal sliding rack 9 and the rack drive gear 10 are fixedly sleeved on the gear shafts. The left and right ends of the gear shafts are rotatably inserted into the shaft holes of the adjacent sliding blocks and the upper side plates 6.

[0043] When the baffle is pushed forward by the scraper, the sliding block is also pushed forward. At this time, the sliding block and the transverse rack produce relative displacement effect. The linkage gear produces relative engagement rolling motion effect relative to the transverse rack, that is, the linkage gear rolls and moves forward relative to the transverse rack. The linkage gear drives the drive gear to rotate in the opposite direction. The drive gear drives the longitudinal rack to slide upward along the sliding groove. At this time, since the scraper is attached to the baffle, the upward sliding longitudinal rack contacts the scraper from below when moving a certain distance. At this time, the scraper produces a lifting effect. The lifting effect not only makes the scraper separate from the baffle, but also plays a role in resetting the scraper, so as to achieve the effect of correcting deviation. After the scraper separates from the baffle, the sliding block is reset to the original position under the action of the spring, and the longitudinal rack also returns to the original position under the reverse motion.

When arranged, the light pole 3 should be parallel to the movement direction of the equipment.

[0046] The slider 4 is slidably mounted on the polished rod 3, based on which the slider 4 can realize linear motion along the polished rod 3. The spring 5 is mounted on the polished rod 3, and the front and rear ends of the spring 5 elastically resist the adjacent fixed seat 2 and the slider 4 respectively. Then, when the slider 4 slides forward by an external force, the slider 4 can compress the spring 5. When the external force acting on the slider 4 is eliminated, the slider 4 can slide to its original position under the rebound action of the spring 5; in this embodiment, the forward direction is the movement direction of the device.

[0047] The upper surface of the slider 4 is a planar structure, and two upper side plates 6 are integrally formed on the upper surface of the slider 4, which are spaced apart and opposite to each other. The transverse rack 7 is arranged with the tooth surface facing upward between the upper side plates 6, and the transverse rack 7 is arranged without contact with the upper side plates 6 and the slider 4; the rear end of the transverse rack 7 is fixedly connected to the fixed seat 2 located on the rear side, and the extension direction of the transverse rack 7 is parallel to the light rod 4.

[0048] A baffle 8 is provided above the transverse rack 7. The bottom end of the baffle 8 is spaced from the transverse rack 7. At the same time, both sides of the baffle 8 are fixedly connected to the upper side plate 6. The upper end of the baffle 8 extends to the upper position of the upper side plate 6. The function of the baffle 8 is to contact the inclined and sinking scraper. The installation height of the baffle 8 is set so that the baffle 8 is on the motion trajectory of the end of the inclined scraper. Then, after the scraper contacts the baffle 8, it can push the baffle 8 to slide.

[0049] A vertically arranged slide groove is provided on the rear surface of the baffle 8, in which a longitudinal rack 9 with the tooth surface facing backward is slidably embedded. The longitudinal rack 9 is in transmission meshing with the drive gear 10 on its rear side, and the drive gear 10 is in transmission meshing with the linkage gear 11 below its rear side, and the linkage gear 11 is in transmission meshing with the transverse rack 7 below it. The longitudinal rack 9 and the drive gear 10 are both arranged between the upper side plates 6. At the same time, the longitudinal rack 9 and the drive gear 10 are fixedly mounted on their respective gear shafts, and the left and right ends of the gear shafts are rotated and inserted into the shaft holes of the adjacent upper side plates 6.

[0050] The using method is: when the baffle 8 is pushed forward by the scraper, the sliding block 4 is also pushed forward, at this time, the relative displacement effect between the sliding block 4 and the transverse rack 7 is generated, and then the relative meshing rolling movement effect of the linkage gear 11 relative to the transverse rack 7 is generated, that is, the linkage gear 11 rolls and moves forward relative to the transverse rack 7, and the linkage gear 11 drives the driving gear 10 to rotate reversely, the driving gear 10 drives the longitudinal rack 9 to slide upward along the sliding groove, at this time, since the scraper is attached to the baffle 8, the longitudinal rack 9 upwardly sliding contacts the scraper from the bottom to the top when moving a certain distance, at this time, the lifting effect is generated on the scraper, the lifting effect not only makes the scraper separate from the baffle 8, but also plays a role of resetting, so that the deviation correction effect is achieved, and after the scraper separates from the baffle 8, the sliding block 4 is reset to the original position under the action of the spring 5, and the longitudinal rack 9 also restores to the original position under the reverse movement.

[0051] After the above scheme is adopted, through the design of the self-deviation correction device, the inclination problem of the scraper can be automatically detected and corrected without manual intervention, the equipment downtime caused by the inclination of the scraper is greatly reduced, and the operation efficiency of the equipment and the slag scraping effect are improved.

This greatly reduces the equipment downtime caused by the inclination of the scraper, improves the operation efficiency of the equipment and the slag scraping effect, the self-deviation correction device detects the inclination state of the scraper in real time through the sliding of the sliding block on the polished rod and the elastic action of the spring. The precise transmission cooperation of the transverse rack, the longitudinal sliding rack, the rack driving gear and the linkage gear is utilized to realize the automatic correction of the inclination of the scraper. Since the self-deviation correction device exists, the inclination problem of the scraper is effectively solved, thereby reducing the maintenance and replacement cost caused by the bending damage of the scraper.
