Description

Technical Field

[0001] This utility model belongs to the field of ductile iron pipe technology, and in particular relates to a discharge device for the production of ductile iron pipes. Background Technology

[0002] The discharge device for ductile iron pipe production is an important piece of equipment used in the production process of ductile iron pipe. It is mainly used to smoothly discharge the ductile iron pipes formed during the casting process from the production line, or to remove the castings from the casting mold.

[0003] If it is inconvenient to automatically unload the cut iron pipes during the pipe discharge process, the overall efficiency of the production line may be reduced due to untimely unloading, which will affect the consistency and quality of the products. Therefore, we have proposed a discharge device for ductile iron pipe production. Utility Model Content

[0004] The purpose of this utility model is to provide a discharge device for the production of ductile iron pipes. The device drives a pulley to rotate via a double-threaded rod, and then the pulley drives a pusher plate to push the cut iron pipe through a transmission, thus solving the problem of automatically discharging the cut iron pipe.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a material discharge device for the production of ductile iron pipes, including a housing, a cutting mechanism inside the housing, and an adjustment mechanism inside the housing;

[0007] The cutting mechanism includes a fixed body, a motor fixedly connected to the inner wall of the fixed body, a bidirectional threaded rod fixedly connected to the output shaft of the motor via a coupling, a threaded cylinder threadedly connected to the outer surface of the bidirectional threaded rod, a cutting blade fixedly connected to the bottom of the threaded cylinder, a limit block fixedly connected to the outer surface of the housing, a sliding plate fixedly connected to the outer surface of the cutting blade, a pulley fixedly connected to the outer surface of the bidirectional threaded rod, a belt driven by the outer surface of the pulley, a pulley two driven by the end of the belt away from the pulley, a threaded rod fixedly connected to the inner wall of the pulley two, a moving plate threadedly connected to the outer surface of the threaded rod, a push plate slidably connected to the inner wall of the moving plate, and a spring fixedly connected to the side of the push plate near the motor. The bidirectional threaded rod drives the pulley to rotate, and the pulley moves the push plate towards the iron pipe through transmission. The spring's rebound pushes the push plate against the iron pipe, achieving automatic discharge of the iron pipe after cutting. This ensures the accuracy of the discharge quantity, speed, and direction, helping to maintain product consistency and quality.

[0008] Furthermore, the outer surface of the fixed body is fixedly connected to the outer surface of the housing, two threaded cylinders are provided, the outer surface of the threaded cylinder is slidably connected to the inner wall of the housing, and the inner wall of the limiting block is rotatably connected to the outer surface of the bidirectional threaded rod.

[0009] Furthermore, the outer surface of the sliding plate is slidably connected to the inner wall of the housing, and four springs are provided in total, with the end of the spring away from the push plate being fixedly connected to the outer surface of the moving plate.

[0010] Furthermore, the adjustment mechanism includes a fixing plate fixedly connected to the inner wall of the housing. There are two fixing plates, and a limit strip is fixedly connected to the side of the fixing plates that are close to each other.

[0011] Furthermore, there are two limiting strips, and a discharge pipe is slidably connected to the outer surface of the limiting strip, and an iron pipe is slidably connected to the inner wall of the discharge pipe.

[0012] Furthermore, a support plate is fixedly connected to the outer surface of the housing, and an adjustment plate is slidably connected to the outer surface of the support plate. By adjusting the plate, which can slide on the support plate, the distance between the adjustment plate and the discharge pipe can be changed, thereby changing the length of the cut iron pipe. This achieves the effect of controlling the length of the cut iron pipe, better controlling the size of the product, and ensuring that the product meets the quality requirements.

[0013] Furthermore, a rotating door is rotatably connected to the inner wall of the housing, and two rotating doors are provided in total. A handle is fixedly connected to the outer surface of the rotating door.

[0014] Furthermore, a collection box is slidably connected to the inner wall of the housing, and the outer surface of the collection box is in contact with the outer surface of the rotating door.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a spring. A first pulley rotates a second pulley via a belt, which in turn rotates a threaded rod. The rotation of the threaded rod causes a moving plate to move towards the iron pipe. This moving plate then moves a push plate, which first contacts the iron pipe. The double-ended threaded rod then rotates the first pulley, which in turn moves the push plate towards the iron pipe. The spring's return causes the push plate to push the iron pipe, achieving automatic discharge of the iron pipe after cutting. This ensures accuracy in discharge quantity, speed, and direction, contributing to product consistency and quality.

[0017] 2. This utility model incorporates an adjusting plate. By loosening the bolts inside the adjusting plate, the plate is released from its fixation on the support plate. The adjusting plate is then moved on the support plate until the distance between it and the discharge pipe is equal to the desired length of the iron pipe to be produced. The bolts are then tightened again to fix the adjusting plate to the support plate. By using an adjusting plate that can slide on the support plate, the distance between the adjusting plate and the discharge pipe can be changed, thereby altering the length of the cut iron pipe. This allows for better control of the cut iron pipe's length, improving product size control and ensuring that the product meets quality requirements.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer surface of 204 is slidably connected to the inner wall of the housing 101.

The housing 101 is connected through the sliding plate 207, and the sliding plate 207 can slide inside the housing 101.

[0029] The adjustment mechanism 3 includes a fixing plate 301 fixedly connected to the inner wall of the housing 101. There are two fixing plates 301. Limiting strips 302 are fixedly connected to the side of the fixing plates 301 that are close to each other. There are two limiting strips 302.

[0031] One specific application of this embodiment is:

[0032] When the operator needs to use the equipment, the device is first adjusted via the adjustment mechanism 3. First, the bolts inside the adjustment plate 306 are loosened to release the fixing of the adjustment plate 306 to the support plate 305. Then, the adjustment plate 306 is moved on the support plate 305 until the distance between the adjustment plate 306 and the discharge pipe 303 is the desired length of the iron pipe to be produced. Then, the bolts inside the adjustment plate 306 are tightened again to fix the adjustment plate 306 to the support plate 305. This allows for better control of the length of the cut iron pipe 304, resulting in better... The feeding process controls the product's dimensions to ensure it meets quality requirements. When the iron pipe 304 is conveyed to contact the adjusting plate 306, the feeding stops, and the motor 202 starts. The motor 202 then rotates the bidirectional threaded rod 203, causing the two threaded cylinders 204 to move closer together. The threaded cylinders 204 then move the cutting blade 205, causing it to cut the iron pipe 304. Simultaneously, the cutting blade 205 also moves the sliding plate 207 within the housing. The sliding mechanism 101 simultaneously drives the double-threaded rod 203 to rotate the pulley 208. The pulley 208 then drives the pulley 210 via the belt 209. The pulley 210 then drives the threaded rod 211 to rotate. This rotation of the threaded rod 211 causes the moving plate 212 to move towards the iron pipe 304. The moving plate 212 then moves the push plate 213 together with the moving plate 213. At this point, the push plate 213 first contacts the iron pipe 304. As the moving plate 212 continues to move, it works in conjunction with the push plate 213 to spring back. Spring 214 compresses the iron pipe 304. When the cutting is completed, spring 214 will quickly rebound, allowing push plate 213 to push the cut iron pipe 304 into collection box 309. This achieves automatic discharge of iron pipe 304 after it is cut, ensuring the accuracy of discharge quantity, speed and direction, which helps maintain product consistency and quality. When there are enough cut iron pipes 304, the rotating door 307 can be opened, and then collection box 309 can be pulled out from housing 101 to collect the iron pipes 304.
