Description

Technical Field

[0001] This utility model relates to the field of fixed-plate sand scraping technology, and in particular to a spring-pressed fixed-plate sand scraping device. Background Technology

[0002] Spring-pressed fixed plate sand scraping devices are mainly used on the fixed plate conveying track of flaskless molding lines. Flaskless molding lines have a fast production pace, and during the repeated carrying and conveying of sand molds, a large amount of sand particles easily stick to the surface of the fixed plate. The function of the spring-pressed fixed plate sand scraping device is to remove the sticky sand from the surface of the fixed plate, ensuring the continuous and stable operation of the flaskless molding line, effectively improving the yield rate and production efficiency of castings, and becoming a key supporting equipment for flaskless molding lines in the modern foundry industry.

[0003] Existing fixed-plate sand scraping devices mostly use hydraulic, pneumatic, or electric motor drives, which require additional power sources. However, while power-driven scraping devices are versatile for removing sand adhering to fixed-plate trolleys on complex surfaces, they are not very effective for fixed-plate trolleys with flat surfaces, and their manufacturing and maintenance costs are relatively high. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a spring-pressed fixed-plate sand scraping device.

[0005] This utility model is achieved by the following technical solution: a spring-pressed fixed plate sand scraping device, including a pressing mechanism, a quick-change mechanism, a slag conveying mechanism and a running mechanism, wherein the quick-change mechanism is located at the bottom of the pressing mechanism, the running mechanism is located at the bottom of the quick-change mechanism, and the slag conveying mechanism is located on both sides of the running mechanism;

[0006] The clamping mechanism includes a support frame, a lifting ring bracket fixedly connected to the bottom of the support frame, a spindle fixedly connected inside the lifting ring bracket, a torsion spring fixedly connected to the outer wall of the spindle, a fixed bracket contacting the end of the torsion spring away from the spindle, a first spindle rotatably connected inside the fixed bracket, a connecting bracket fixedly connected to the outer wall of the first spindle, the connecting bracket fixedly connected to the bottom of the lifting ring bracket, and a limit bracket fixedly connected to the outer wall of the spindle, the limit bracket contacting the outer wall of the fixed bracket.

[0007] Through the above technical solution, the support frame supports the lifting ring bracket and the connecting bracket. The connecting bracket is fixed to the spindle. The torsion spring is sleeved on the outer wall of the spindle. The end of the torsion spring away from the spindle is fixedly connected to the outer wall of the spindle to prevent the torsion spring from rotating. The spindle is fixed to the lifting ring bracket, and the lifting ring bracket provides support for the spindle. The end of the torsion spring away from the spindle presses against the fixed bracket. The fixed bracket rotates on the outer wall of the spindle. The pressure of the torsion spring allows the fixed bracket to rotate around the spindle. Under the action of the torsion spring, the scraper is pressed tightly against the surface of the trolley. No additional power source is required. The scraping function can be directly realized during the conveyor line push. Its structure is simple, uses less material, occupies less space, is easy to maintain, and has low cost. At the same time, the limiting bracket is fixed to the outer wall of the spindle. The limiting bracket limits the fixed bracket and prevents the fixed bracket from rotating too much due to the elasticity of the torsion spring.

[0008] As a further improvement to the above solution, the quick-change mechanism includes a screw, which is threadedly connected inside the fixed bracket, and a pressure plate is threadedly connected to the screw.

[0009] As a further improvement to the above solution, a screw is threadedly connected to the inside of the pressure plate, a scraper is slidably connected to the outer wall of the screw, and the pressure plate is threadedly connected to the screw.

[0010] Through the above technical solution, the screw is threadedly connected to the fixed bracket and the pressure plate. The screw passes through the scraper and is threadedly connected to the pressure plate. The scraper is fixed between the pressure plate and the pressure plate. By disassembling the screw, the scraper can be quickly replaced. The scraper is composed of a hacksaw blade. When the trolley passes over the scraper section, the sand layer adhering to the upper surface of the trolley is removed by the scraper, which is tightly attached to the trolley surface. The hacksaw blade, as a key component for sand scraping, has simple procurement channels, low cost, and is easy to maintain, which can greatly reduce spare parts and labor costs.

[0011] As a further improvement to the above solution, the slag conveying mechanism includes a support plate, a fixing plate is fixedly connected to the outer wall of the support plate, and a motor is fixedly connected to the top of the fixing plate.

[0012] As a further improvement to the above solution, a rotating rod is fixedly connected to the output end of the motor, the rotating rod is rotatably connected inside the support plate, and a conveyor belt is rotatably connected to the outer wall of the rotating rod.

[0013] Through the above technical solution, the motor drives the conveyor belt to rotate via the rotating rod, thereby transporting the residue that falls on the surface of the conveyor belt to a designated location for convenient unified treatment by the user.

[0014] As a further improvement to the above solution, the operating mechanism includes a track, and a trolley is slidably connected to the inner wall of the track.

[0015] As a further improvement to the above scheme, two tracks are provided, which are symmetrically arranged with the trolley as the center.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model supports the lifting ring bracket and the connecting bracket through a support frame. The connecting bracket is fixed to the mandrel. A torsion spring is sleeved on the outer wall of the mandrel. The end of the torsion spring away from the mandrel is fixedly connected to the outer wall of the mandrel to prevent the torsion spring from rotating. The mandrel is fixed to the lifting ring bracket, which provides support for the mandrel. The end of the torsion spring away from the mandrel presses against the fixed bracket. The fixed bracket rotates on the outer wall of the mandrel. The pressure of the torsion spring allows the fixed bracket to rotate around the mandrel. Under the action of the torsion spring, the scraper is pressed tightly against the surface of the trolley. No additional power source is required. The scraping function can be directly realized during the conveyor line push. Its structure is simple, uses less material, occupies less space, is easy to maintain, and has low cost. At the same time, the limiting bracket is fixed to the outer wall of the mandrel. The limiting bracket limits the fixed bracket and prevents the fixed bracket from rotating too much due to the elasticity of the torsion spring.

[0018] This invention utilizes a screw threaded connection between the screw rod and the fixed bracket and pressure plate. The screw rod passes through the scraper and is threadedly connected to the pressure plate. The scraper is fixed between the pressure plate and the pressure plate. By disassembling the screw rod, the scraper can be quickly replaced. The scraper is composed of a hacksaw blade. When the trolley passes over the scraper section, the sand layer adhering to the upper surface of the trolley is removed by the scraper, which is tightly attached to the trolley surface. The hacksaw blade, as the main component for sand scraping, has simple procurement channels, low cost, and is easy to maintain, significantly reducing spare parts and labor costs.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-6 The spring-pressed fixed plate sand scraping device in this embodiment includes a pressing mechanism 1, a quick-change mechanism 2, a slag conveying mechanism 3 and a running mechanism 4. The quick-change mechanism 2 is located at the bottom of the pressing mechanism 1, the running mechanism 4 is located at the bottom of the quick-change mechanism 2, and the slag conveying mechanism 3 is located on both sides of the running mechanism 4.

[0030] The clamping mechanism 1 includes a support frame 101. A lifting ring bracket 102 is fixedly connected to the bottom of the support frame 101. A spindle 103 is fixedly connected inside the lifting ring bracket 102. A torsion spring 104 is fixedly connected to the outer wall of the spindle 103. A fixed bracket 105 is disposed in contact with the end of the torsion spring 104 away from the spindle 103. A spindle 106 is rotatably connected inside the fixed bracket 105. A connecting bracket 107 is fixedly connected to the outer wall of the spindle 106. The connecting bracket 107 is fixedly connected to the bottom of the lifting ring bracket 102. A limit bracket 108 is fixedly connected to the outer wall of the spindle 103. The limit bracket 108 is disposed in contact with the outer wall of the fixed bracket 105.

[0031] The quick-change mechanism 2 includes a screw 201, which is threadedly connected inside the fixed bracket 105, and a pressure plate 202 is threadedly connected to the screw 201.

[0032] The pressure plate 202 is internally threaded with a screw 203, the outer wall of the screw 203 is slidably connected with a scraper 204, and the screw 203 is threadedly connected with a pressure plate 205.

[0033] The slag conveying mechanism 3 includes a support plate 301, a fixing plate 302 is fixedly connected to the outer wall of the support plate 301, and a motor 303 is fixedly connected to the top of the fixing plate 302.

[0034] A rotating rod 304 is fixedly connected to the output end of the motor 303. The rotating rod 304 is rotatably connected inside the support plate 301. A conveyor belt 305 is rotatably connected to the outer wall of the rotating rod 304.

[0035] The running mechanism 4 includes a track 401, and a trolley 402 is slidably connected to the inner wall of the track 401.

[0036] There are two tracks 401, which are symmetrically arranged with the trolley 402 as the center.

[0037] The implementation principle of the spring-pressed fixed-disc scraping device in this embodiment is as follows: When the trolley 402 slides along the outer wall of the track 401, the trolley 402 slides in a specified direction. The support frame 101 supports the lifting ring bracket 102 and the connecting bracket 107. The spindle 106 is fixed inside the connecting bracket 107. The torsion spring 104 is sleeved on the outer wall of the spindle 106. At the same time, the end of the torsion spring 104 away from the spindle 106 is fixedly connected to the outer wall of the spindle 103, thereby preventing the torsion spring 104 from rotating. The spindle 103 is fixed to the lifting ring bracket 102, and the lifting ring bracket 102 provides support for the spindle 103. The end of the torsion spring 104 away from the spindle 103 presses against the fixed bracket 105. At the same time, the fixed bracket 105 rotates on the outer wall of the spindle 106. The pressure of the torsion spring 104 allows the fixed bracket 105 to rotate around the spindle 106. Under the action of the torsion spring 104, the fixed bracket 105 can rotate around the spindle 106. The scraper 204 is pressed tightly against the surface of the trolley 402, thus eliminating the need for an additional power source. It can directly perform the scraping function during the conveyor line's pushing process. Its structure is simple, uses few materials, occupies little space, is easy to maintain, and has low cost. Simultaneously, the limiting bracket 108 is fixed to the outer wall of the spindle 103, limiting the fixed bracket 105 and preventing it from rotating too much due to the elasticity of the torsion spring 104. At the same time, the screw 201 and the fixed bracket 105... The pressure plate 202 is threaded, and the screw 203 passes through the scraper 204 and is threaded to the pressure plate 205 and the pressure plate 202. The scraper 204 is fixed between the pressure plate 202 and the pressure plate 205. The scraper 204 can be quickly replaced by removing the screw 203. The scraper 204 is made of a hacksaw blade. When the trolley 402 passes through the scraper section, the sand layer adhering to the upper surface of the trolley 402 will be removed by the scraper 204 which is tightly attached to the surface of the trolley 402. As a key component for scraping sand, hacksaw blades are easy to procure, low in cost, and easy to maintain, which can greatly reduce spare parts and labor costs. When the motor drives the rotating rod to rotate, a fixing plate is fixed on the outer wall of the motor to support the motor. At the same time, the rotating rod rotates inside the support plate, which is fixed to the fixing plate. Meanwhile, a conveyor belt rotates on the outer wall of the rotating rod. When the conveyor belt runs, it transports the residue scraped off the trolley to a designated location for workers to handle.
