Description

Technical Field

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

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

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

[0004] Normally, there are two chains, which are driven by the same driving roller to achieve synchronous operation. The scraper is placed horizontally between the two chains. A retractable structure is usually used 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 respectively fixed on the scraper and the chain, while the inner tube is placed in the outer tube and the two are connected by a spring. On the basis of this retractable structure, when the scraper contacts the bottom of the groove, it will be pushed by the spring, which can increase the contact force between the scraper and the bottom of the groove 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 may get stuck, which causes one end of the scraper to be higher than 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 may cause the entire scraper to bend and damage over time.

[0006] In this process, monitoring sensors are generally installed on both sides of the machine. The distance between the sensors on both sides and the end of the scraper 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 is detected, an alarm is triggered. At this time, the management personnel needs 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 coiled material glue scraping device with automatic edge finding, discloses a self-adhesive waterproof coiled material glue scraping device with automatic edge finding, the device is used for scraping glue on the back of the coiled material, the coiled material is driven to move by a guide roller, the device comprises a glue coating mold, a glue supply system, a movable frame, a guide rail, a correction hydraulic mechanism and a correction detector, the glue supply system, the glue coating 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 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 of the equipment and the scraping effect 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, comprising:

[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 correction component is installed on the trough wall of the discharge trough.

[0014] The correction component has:

[0015] There are two fixing seats in total, and the two fixing seats 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 plate is slidably mounted on the slider, and the baffle plate can push the scraper;

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

[0021] The baffle driving mechanism comprises a driving gear and a longitudinal rack. The driving gear is rotatably mounted on the slider. The baffle is provided with a longitudinal rack matched with 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 meshed with the driving gear, and the other side is meshed with the transverse rack.

[0023] The return mechanism is a spring, which is sleeved on the polished rod, the first end of the spring is in contact with the slider, and the second end of the spring is in contact with 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 the tooth surface facing upwards. 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.

[0027] The method of using the above-mentioned 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 movement 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 longitudinal rack sliding upward 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 movement.

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

The return mechanism is a spring 5, which is sleeved on the light rod 3, the first end of the spring 5 is in contact with the slider 4, and the second end of the spring 5 is in contact with a fixed seat 2.

[0041] The upper surface of the slider 4 is integrally formed with two upper side plates 6 spaced apart from each other. The transverse rack 7 is arranged between the two upper side plates 6 with the tooth surface facing upward, and the transverse rack 7 is arranged without contacting the upper side plates 6 and the slider 4. The slider 4 is slidably mounted on the light rod 3, based on which the slider 4 can realize linear motion along the light rod 3. The spring 5 is mounted on the light 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 under 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 the original position under the rebound action of the spring 5; in this embodiment, the forward direction is the movement direction of the device. The upper surface of the slider 4 is a planar structure, and two slider upper side plates 6 that are spaced apart and opposite to each other are integrally formed on the upper surface of the slider 4. The transverse rack 7 is arranged with its tooth surface facing upward at a position 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.

The spring 5 is mounted on the light 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 under the 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 the 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 with a left and right interval therebetween. The transverse rack 7 is arranged between the upper side plates 6 with the tooth surface facing upward, 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 plate 8 is provided above the transverse rack 7, and the bottom end of the baffle plate 8 is spaced from the transverse rack 7. Both sides of the baffle plate 8 are fixedly connected to the upper side plate 6, and the upper end of the baffle plate 8 extends to the upper position of the upper side plate 6. The baffle plate 8 functions to contact the inclined and sinking scraper.

Then, the scraper can push the baffle plate 8 to slide after contacting the baffle plate 8.

[0049] A vertically arranged slide groove is provided on the rear surface of the baffle 8, and a longitudinal rack 9 with the tooth surface facing backward is slidably embedded in the slide groove. The longitudinal rack 9 is in transmission meshing engagement with a driving gear 10 on its rear side, and the driving gear 10 is in transmission meshing engagement with a linkage gear 11 below its rear side, and the linkage gear 11 is in transmission meshing engagement with the transverse rack 7 below it.

[0050] Instructions for use: When the baffle 8 is pushed forward by the scraper, the slider 4 is also pushed forward. At this time, a relative displacement effect is generated between the slider 4 and the transverse rack 7, and then the linkage gear 11 produces a relative meshing and rolling movement effect relative to the transverse rack 7, that is, the linkage gear 11 rolls forward relative to the transverse rack 7, and the linkage gear 11 drives the driving gear 10 to rotate in the opposite direction, and the driving gear 10 drives the longitudinal rack 9 to slide upward along the slide groove. At this time, since the scraper is attached to the baffle 8, the longitudinal rack 9 sliding upward contacts the scraper from bottom to top when moving 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 8, but also plays a role in restoring it, thereby achieving the effect of correcting the deviation. After the scraper separates from the baffle 8, under the action of the spring 5, the slider 4 is reset to its original position, and the longitudinal rack 9 is also restored to its original position under the reverse movement.

This greatly reduces the equipment downtime caused by the inclination of the scraper, improves the equipment's operating efficiency and scraping effect; the self-correcting device detects the inclination of the scraper in real time through the sliding of the slider on the polished rod and the elastic action of the spring.
