Description

Technical Field

[0001] The present invention relates to the technical field of production tools, and more particularly to a recycling and sorting machine for standard building parts. Background Art

[0002] When pouring concrete in modern buildings, aluminum alloy formwork is often used to provide a standardized shape for the concrete pouring operation and improve efficiency. The installation of aluminum alloy formwork requires the use of a variety of standard parts for fixing and installation, including pins, small nuts, large nuts, small screws, dowels, large nuts, long dowels, long screws, and square washers. After the concrete pour is completed, the standard parts and aluminum alloy formwork need to be removed for recycling and reuse. Because the standard parts adhere to the concrete, they are collected and cleaned, and the concrete is removed before they are reclassified for recycling and reuse.

[0003] These standard parts are now sorted by sorting machines to avoid the labor and time of manual sorting. For example, an automated intelligent sorting device with publication number CN112024407A includes a vibrating disk and a main sorting mechanism. The vibrating disk is provided with a conveying channel that rises in a spiral and extends to the outside of the vibrating disk. The main sorting mechanism is connected to the outlet of the conveying channel. The main sorting mechanism includes a sorting main channel and a pin channel, a K-plate nut channel, a K-plate screw channel, a pin channel, and a tension wire nut channel that are sequentially arranged along the sorting main channel and respectively connected to the sorting main channel. The sorting device can sort pins, K-plate nuts (equivalent to small nuts), K-plate screws (equivalent to small screws), pins, and tension wire nuts (equivalent to large nuts).

[0004] While the aforementioned sorting device can sort a variety of standard parts, it is unable to sort large screws, long pins, long screws, and square washers. The main difference between large nuts, long pins, long screws, and small screws lies in their length, and the sorting device itself is difficult to distinguish. The width of square washers differs significantly from that of other standard parts, making both transportation and sorting difficult, especially for square washers. Therefore, the aforementioned sorting device is unable to sort all the standard parts that will be used at once. Summary of the Invention

[0005] In order to overcome the problem of difficulty in sorting different types of standard parts at one time in the above-mentioned prior art, the present invention provides a construction standard parts recycling and sorting machine that can sort out the existing various standard parts.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is: a recycling and sorting machine for standard parts for construction, comprising a vibrating plate and a main sorting channel, wherein a conveying channel that rises and extends to the outside of the vibrating plate is provided in the vibrating plate, the main sorting channel is connected to the end of the conveying channel, the vibrating plate is further provided with a first material dividing plate and a second material dividing plate; the conveying channel is arranged with a hollow portion along its direction; the main sorting channel comprises a primary screening channel and a second screening channel, the first material dividing plate is connected to the outer edge of the primary screening channel, and the second material dividing plate is connected to the second screening channel; the outer edge of the primary screening channel is further provided with a primary screening plate, and the primary screening plate forms a gap with the primary screening channel; the second The outer edge of the sieve channel is provided with a locking raised edge and a large nut outlet connected to the outside world is provided on the second sieve channel; the first dividing plate is inclined toward the bottom of the vibration disk on the side away from the primary screening channel and is provided with a baffle portion, and a gasket outlet and a pin outlet groove are provided on the baffle portion in sequence. The first dividing plate is located near the gasket outlet and is provided with a top portion extending toward the gasket outlet. The distance between the connection between the top portion and the first dividing plate and the baffle portion is greater than the width of the pin and less than the width of the square gasket; the second dividing plate is provided with multiple discharge ports on the side close to the locking raised edge, and the farther the discharge port is from the primary screening channel, the longer its length is.

[0007] In the above technical solution, the standard parts are placed in the vibration disk, and with the action of the vibration disk, all the standard parts will rise along the conveying channel. The width of the conveying channel is equal to or greater than the width of the square gasket, and the hollow portion is located on the side of the conveying channel close to the center of the vibration disk. The width of the side of the conveying channel close to the inner side of the vibration disk is close to the width of the other standard parts except the square gasket. The purpose of this setting is that if the width of the conveying channel is too small, the square gasket cannot be transported. If the width of the conveying channel is too large, the other standard parts will not be in the right posture and cannot fall back into the vibration disk to be transported again, affecting subsequent sorting. The provision of the hollow portion allows other standard parts to fall back from the hollow portion to the bottom of the vibration disk for re-transportation, while allowing the overall width of the conveying channel to be able to transport the square gasket.

[0008] After the standard parts are transported to the main sorting channel, they first enter the primary screening channel. In the primary screening channel, the gap between the primary screening plate and the primary screening channel is greater than the thickness of the pin, small nut and square gasket, but smaller than the thickness of the large nut and the width of the head of the small screw, large screw, pin, long pin and long screw. Therefore, the pin, small nut and square gasket will enter the first dividing plate from the gap, while the large nut, pin, large screw, long pin and long screw will continue to be transported to the second screening channel.

[0009] The pin, small nut, and square gasket that enter the first dividing plate will continue to advance along the baffle portion due to the inclined setting of the first dividing plate. When they reach the top portion, the pin and small nut are narrow in width and pass between the top portion and the baffle portion. The square gasket is wider. After the square gasket contacts the top portion, it gradually stands up and moves forward along the top portion because the top portion extends toward the gasket outlet. Until the square gasket moves to the gasket outlet, flips over from the gasket outlet, and leaves the vibrating disk. The pin that continues to advance will leave the vibrating disk through the pin outlet slot, where the width of the pin outlet slot is greater than the thickness of the pin but less than the thickness of the small nut. The small nut eventually leaves the second dividing plate at the end of the second dividing plate.

[0010] The heads of the small screw, large screw, pin, long pin, and long screw entering the secondary screening channel abut against the raised edge of the positioning block. One end receives support from the secondary screening channel, while the other end extends onto the second sorting plate, where it is supported. This allows these three components to smoothly advance along the secondary screening channel. Without this posture, these three standard components would fall back to the bottom of the vibrating plate due to the limited width of the main sorting channel. When the small screw, large screw, pin, long pin and long screw move to the first discharge port, the length of the discharge port is the smallest, only larger than the length of the small screw. At this time, one end of the small screw is no longer supported by the second dividing plate, so it falls into the discharge port under the action of gravity; while the pin, large screw, long pin and long screw continue to move forward. Based on the same principle as the small screw falling into the discharge port, the pin, large screw, long pin and long screw fall into the corresponding discharge port in order from short to long according to their length, completing the sorting of these five standard parts.

[0011] The large nut outlet can be set at any point in the secondary sieve channel, closer to the primary sieve channel than the discharge port, or at the end of the secondary sieve channel. The width of the large nut outlet is larger than that of the large nut, so the large nut can fall out. However, small screws, large screws, pins, long pins, and long screws are supported at both ends to prevent them from falling. Therefore, small screws, large screws, pins, long pins, and long screws can also pass through the large nut outlet smoothly. Similarly, due to the restriction of the raised edge of the blocking position, the large nut will not enter the second dividing plate.

[0012] Preferably, the baffle portion is groove-shaped, including a bottom plate, a first side plate and a second side plate located on both sides of the bottom plate, the first side plate being connected to the first dividing plate and the connection between the two being a right angle or an obtuse angle; the gasket outlet passes through the second side plate and at least a portion of the bottom plate; the pin plate outlet groove is provided on the bottom plate. The pin plate and the small nut will enter the groove formed by the baffle portion, and will move forward restricted by the baffle portion. They will not fall directly out of the vibration disk due to vibration, ensuring that they leave the vibration disk at the right position. The square gasket will contact the bottom plate and the second dividing plate at the same time, and since a right angle or an obtuse angle is formed between the first side plate and the second dividing plate, the square gasket will stand up and move forward in this state, making it easier for the square gasket to move along the top portion and flip out from the gasket outlet.

[0013] Preferably, the vertical distance between the end of the raised portion away from the first divider plate and the first divider plate is greater than half the width of the square gasket. The square gasket gradually moves forward along the raised portion. When the square gasket contacts the end of the raised portion away from the first divider plate, since the vertical distance between this position and the first divider plate is greater than half the width of the square gasket, the square gasket is now upright and its center of gravity moves to the upper half of the square gasket, causing the square gasket to gradually tilt and eventually become unstable and flip over. At this time, since the flipped point of the square gasket is located at the gasket outlet, the flipped square gasket will exit through the gasket outlet.

[0014] Preferably, the raised portion extends to a position flush with the gasket outlet in the vertical direction. When the square gasket moves to the end of the raised portion, the square gasket will be flush with the gasket outlet in the vertical direction. At this time, if the square gasket flips over, it will inevitably leave the vibration plate from the gasket outlet.

[0015] Preferably, a height limiting plate is provided on the second screen channel, and the height limiting plate is located just above the positioning raised edge, and the height limiting plate is provided with notches corresponding to the discharge port, respectively. A gap is formed between the height limiting plate and the positioning raised edge, and the gap is smaller than the width of the heads of small screws, large screws, pins, long pins and long screws, and larger than the diameter of the rods of these standard parts, so that their rods can pass through the height limiting plate and the positioning raised edge, while the heads of the standard parts are restricted by both, further preventing the bolts from falling out of the disc body. The height limiting plate can be connected to the two ends of the outer edge of the main channel at both ends, or an inner baffle can be provided on the inner edge of the main sorting channel first, and the inner surface of the height limiting plate is connected to the inner baffle through the connecting rod. Preferably, the solution of providing an inner baffle is adopted, and the inner baffle can also prevent the standard parts from falling back into the disc body. The notch allows these standard parts to fall into the dispensing port without the height limiting plate hindering the movement of the standard parts.

[0016] Preferably, the large nut outlet is located between the inner baffle and the locking raised edge and closer to the inner baffle. The heads of small screws, large screws, pins, long pins, and long screws have a larger contact area on the secondary screen channel, allowing for smoother movement and further preventing small screws and pins from falling into the large nut outlet.

[0017] Preferably, the side of the second dividing plate away from the vibrating plate is inclined toward the bottom of the vibrating plate. The inclined setting means that the standard part is also inclined downward during the movement, and it is more likely to fall into the discharge port because the center of gravity falls on the end near the discharge port.

[0018] Preferably, the second distributor plate is provided with a cover plate at the discharge port, the cover plate being slidably connected to the second distributor plate. When the lengths of standard components such as small screws, large screws, pins, long pins, and long screws vary, the length of the discharge port can be changed by adjusting the cover plate, allowing the discharge port to accommodate small screws, large screws, pins, long pins, and long screws of different lengths.

[0019] Preferably, the primary screening plate is provided with an adjustment bar for adjusting the posture of the standard parts. The adjustment bar can make the rods of small screws, large screws, pins, long pins and long screws face the second material separation plate, preventing them from falling back into the vibrating plate due to incorrect posture, thereby improving sorting efficiency.

[0020] Compared with the existing technology, the beneficial effect of the present invention is that the pins, small nuts and square washers are screened onto the first dividing plate through the action of the primary screening channel and the primary screening plate, and then the three are sorted by the baffle part, so that the pins, small nuts and square washers fall out of the vibrating plate from three fixed positions for easy collection. The remaining standard parts enter the secondary screening channel, among which the large nuts fall directly out of the large nut outlet of the secondary screening channel to the outside of the vibrating plate, while the remaining small screws, large screws, pins, long pins and long screws fall into the discharge port of the second dividing plate in turn, and all leave the vibrating plate through the discharge port, so that one sorting machine can sort multiple standard parts, thereby improving the sorting efficiency of standard parts.

[0027] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0028] Example 1

[0029] like Figure 1-3The figure shows an embodiment of a recycling and sorting machine for standard parts for construction, comprising a vibrating plate 1 and a main sorting channel 2, wherein a conveying channel 3 that rises and extends to the outside of the vibrating plate 1 is provided in the vibrating plate 1, the main sorting channel 2 is connected to the end of the conveying channel 3, and the vibrating plate 1 is further provided with a first dividing plate 4 and a second dividing plate 5; the conveying channel 3 is provided with a hollow portion 301 arranged along its direction; the main sorting channel 2 comprises a primary screening channel 201 and a secondary screening channel 202, the first dividing plate 4 is connected to the outer edge of the primary screening channel 201, and the second dividing plate 5 is connected to the secondary screening channel 202; a primary screening plate 2011 is further provided on the outer edge of the primary screening channel 201, and a gap is formed between the primary screening plate 2011 and the primary screening channel 201; a locking raised edge 2021 is provided on the outer edge of the secondary screening channel 202, and a locking raised edge 2021 is provided on the outer edge of the secondary screening channel 202 A large nut outlet 2022 communicating with the outside world is provided on it; the first dividing plate 4 is inclined toward the bottom of the vibration disk 1 on the side away from the primary screening channel 201 and is provided with a baffle portion 6, and a gasket outlet 601 and a pin outlet groove 602 are provided on the baffle portion 6 in sequence. The first dividing plate 4 is located near the gasket outlet 601 and is provided with a top portion 401 extending toward the gasket outlet 601. The distance between the top portion 401 and the first dividing plate 4 and the baffle portion 6 at the connection between the top portion 401 and the first dividing plate 4 is greater than the width of the pin but less than the width of the square gasket; the second dividing plate 5 is provided with multiple discharge ports 501 on the side close to the locking raised edge 2021. The farther the discharge port 501 is from the primary screening channel 201, the longer its length. The length direction of the discharge port 501 in this embodiment is the straight line connection direction between the second screening channel 202 and the outer edge of the second dividing plate 5.

[0030] Infrared sensors for counting can be provided at the large nut outlet 2022, the gasket outlet 601, the pin outlet slot 602, each discharge port 501 and the end of the baffle portion 6 to record the number of corresponding standard parts leaving from the corresponding outlet.

[0031] The working principle or workflow of this embodiment is as follows: Figure 4 As shown, the standard parts are placed into the vibration disk 1, and with the action of the vibration disk 1, all the standard parts will rise along the conveying channel 3. The width of the conveying channel 3 is equal to or greater than the width of the square gasket 7, and the hollow portion 301 is located on the side of the conveying channel 3 close to the center of the vibration disk 1. The width of the side of the conveying channel 3 close to the inner side of the vibration disk 1 is close to the width of the other standard parts except the square gasket. The purpose of this setting is that if the width of the conveying channel 3 is too small, the square gasket 7 cannot be conveyed. If the width of the conveying channel 3 is too large, the other standard parts are in the wrong posture and cannot fall back into the vibration disk 1 to be conveyed again, affecting the subsequent sorting. The provision of the hollow portion 301 allows other standard parts to fall back from the hollow portion 301 to the bottom of the vibration disk 1 for re-conveying, while allowing the overall width of the conveying channel 3 to be able to convey the square gasket.

[0032] After the standard parts are transported to the sorting main channel 2, they first enter the primary screening channel 201. In the primary screening channel 201, the gap between the primary screening plate 2011 and the primary screening channel 201 is greater than the thickness of the pin 8, small nut 9 and square gasket 7, but smaller than the thickness of the large nut 10 and the width of the heads of the small screw 11, large screw 12, pin 13, long pin and long screw. Therefore, the pin 8, small nut 9 and square gasket 7 will enter the first dividing plate 4 from the gap, while the large nut 10, small screw 11, pin 13, large screw 12, long pin and long screw will continue to be transported to the second screening channel 202.

[0033] The pin 8, small nut 9, and square gasket 7 that enter the first dividing plate 4 will continue to advance along the baffle portion 6 due to the inclined setting of the first dividing plate 4. When they advance to the top portion 401, the pin 8 and small nut 9 are smaller in width and pass between the top portion 401 and the baffle portion 6. The square gasket 7 is wider. After the square gasket 7 contacts the top portion 401, the top portion 401 extends toward the gasket outlet 601, gradually standing up and moving forward along the top portion 401 until the square gasket 7 moves to the gasket outlet 601, flips over from the gasket outlet 601, and leaves the vibrating disk 1. The pin 8 that continues to advance will leave the vibrating disk 1 through the pin outlet slot 602, where the width of the pin outlet slot 602 is greater than the thickness of the pin 8 but less than the thickness of the small nut 9. The small nut 9 eventually leaves the second dividing plate 5 at the end of the second dividing plate 5.

[0034] The heads of the small screw 11, large screw 12, pin 13, long pin, and long screw entering the second screening channel 202 abut against the positioning raised edge 2021, and one end is supported by the second screening channel 202, while the other end extends to the second dividing plate 5 and is supported by the second dividing plate 5, allowing the three components to move smoothly along the second screening channel 202. If they move in a different posture, the three standard components will fall back to the bottom of the vibrating plate 1 due to the limited width of the main sorting channel 2. When the small screw 11, large screw 12, pin 13, long pin and long screw move to the first discharge port 501, the length of the discharge port 501 is the smallest, only larger than the length of the small screw 11. At this time, one end of the small screw 11 is no longer supported by the second dividing plate 5, so it falls into the discharge port 501 under the action of gravity; while the large screw 12, pin 13, long pin and long screw continue to move forward. Based on the principle of the small screw 11 falling into the discharge port 501 mentioned above, the pin 13, large screw 12, long pin and long screw fall into the corresponding discharge port 501 in order of their length from short to long, completing the sorting of these five standard parts.

[0035] The large nut outlet 2022 can be set at any position of the second sieve channel 202, and can be closer to the primary sieve channel 201 than the discharge port 501, or can be located at the end of the second sieve channel 202. The width of the large nut outlet 2022 is greater than that of the large nut, so the large nut 10 can fall, but the small screw 11, large screw 12, pin 13, long pin and long screw rod are supported at both ends and will not fall. Therefore, the small screw 11, large screw 12, pin 13, long pin and long screw rod can also pass through the large nut outlet 2022 smoothly. Similarly, due to the restriction of the locking raised edge 2021, the large nut will not enter the second material dividing plate 5.

[0036] The beneficial effects of this embodiment are as follows: the pins, small nuts and square washers are screened onto the first dividing plate 4 through the action of the primary screening channel 201 and the primary screening plate 2011, and then the three are sorted by the baffle portion 6, so that the pins, small nuts and square washers fall out of the three fixed positions to the outside of the vibration disk 1 for easy collection. The remaining standard parts enter the secondary screening channel 202, among which the large nuts directly fall out of the large nut outlet 2022 of the secondary screening channel 202 to the outside of the vibration disk 1, and the remaining small screws, large screws, pins, long pins and long screws fall into the discharge port 501 of the second dividing plate 5 in turn, and all leave the vibration disk 1 through the discharge port 501, so that one sorting machine can sort a variety of standard parts, thereby improving the sorting efficiency of standard parts.

[0037] Example 2

[0038] A second embodiment of a construction standard parts recycling and sorting machine is based on the first embodiment, and differs from the first embodiment in that: Figure 1 and Figure 3 As shown, the vibration plate 1 is further defined.

[0039] Specifically, the baffle portion 6 is groove-shaped and includes a base plate 603, a first side plate 604, and a second side plate 605 located on either side of the base plate 603. The first side plate 604 is connected to the first separator plate 4 at a right angle or an obtuse angle. The gasket outlet 601 passes through the second side plate 605 and at least a portion of the base plate 603. The pin plate outlet slot 602 is provided on the base plate 603. The pin plate and small nut enter the groove formed by the baffle portion 6 and advance under the restriction of the baffle portion 6. They will not fall directly out of the vibration disk 1 due to vibration, ensuring that they leave the vibration disk 1 in the correct position. The square gasket will contact the base plate 603 and the second separator plate 5 at the same time. Due to the obtuse angle formed between the first side plate 604 and the second separator plate 5, the square gasket will stand upright and advance in this state, making it easier for the square gasket to advance along the top portion 401 and flip out of the gasket outlet 601.

[0040] Furthermore, the vertical distance between the end of the top portion 401 away from the first dividing plate 4 and the first dividing plate 4 is greater than half the width of the square gasket. The square gasket gradually moves forward along the top portion 401. When the square gasket contacts the end of the top portion 401 away from the first dividing plate 4, because the vertical distance between this position and the first dividing plate 4 is greater than half the width of the square gasket, the square gasket has now been erected and its center of gravity will move to the upper half of the square gasket, causing the square gasket to gradually tilt and eventually become unstable and flip over. At this time, since the point where the square gasket flips is located at the gasket outlet 601, the flipped square gasket will exit from the gasket outlet 601. The top portion 401 extends to a position that is vertically aligned with the gasket outlet 601. When the square gasket moves to the end of the top portion 401, the square gasket will be aligned with the vertical position of the gasket outlet 601. At this time, as long as the square gasket flips, it will inevitably leave the vibration disk 1 from the gasket outlet 601.

[0041] The remaining features and working principles of this embodiment are consistent with those of embodiment 1.

[0042] Example 3

[0043] Example 3 of a construction standard parts recycling and sorting machine, based on Example 1 or 2, further defines Example 1 or 2, such as Figure 1-Figure 2 As shown, the difference from Example 2 is that:

[0044] Specifically, a height limiting plate 2023 is provided on the second sieve channel 202. The height limiting plate 2023 is located directly above the locking raised edge 2021. The height limiting plate 2023 is provided with notches 2031 corresponding to the discharge port 501. The height limiting plate 2023 and the locking raised edge 2021 form a gap. The gap is smaller than the width of the head of a small screw, a large screw, a pin, a long pin, and a long screw, and larger than the diameter of the rod of these standard parts. This allows the rods to pass through the height limiting plate 2023 and the locking raised edge 2021, while the heads of the standard parts are restricted by both, further preventing the bolts from falling out of the disk. An inner baffle 2024 is provided on the inner edge of the second sieve channel 202. The inner surface of the height limiting plate 2023 is connected to the inner baffle 2024 via a connecting rod portion 2231. The inner baffle 2024 also prevents the standard parts from falling back into the disk. The notch 2031 allows the standard parts to fall into the material distribution port without the height limiting plate 2023 hindering the movement of the standard parts.

[0045] The large nut outlet 2022 is located between the inner baffle 2024 and the raised retaining edge 2021, and is closer to the inner baffle 2024. The heads of small screws, large screws, pins, long pins, and long screws have a larger contact area on the secondary sieve channel 202, ensuring smoother movement and further preventing small screws and pins from falling into the large nut outlet 2022. In this embodiment, the large nut outlet 2022 is located on the side of the secondary sieve channel 202 close to the primary sieve channel 201.

[0046] In this embodiment, the side of the second dividing plate 5 away from the vibrating plate 1 is tilted toward the bottom of the vibrating plate 1. The tilted setting means that the standard component is also tilted downward during the movement, and when it reaches the discharge port 501, it is more likely to fall into the discharge port 501 because the center of gravity is located on the end near the discharge port 501.

[0047] Furthermore, the second distributor plate 5 is provided with a cover plate 502 at the discharge port 501, which is capable of adjusting the length of the discharge port 501. The cover plate 502 is slidably connected to the second distributor plate 5. In this embodiment, the second distributor plate 5 is provided with a connecting portion 503, and the cover plate 502 is provided with a slide groove 5021. The slide groove 5021 is slidably connected to the connecting portion 503, wherein the connecting portion 503 is a threaded hole on which a fastener is installed.

[0048] In addition, the primary screening plate 2011 is provided with an adjustment bar 2111 for adjusting the posture of the standard parts. The adjustment bar 2111 can make the rods of small screws, large screws, pins, long pins and long screws face the second material distribution plate 5, preventing them from falling back into the vibrating plate 1 due to incorrect posture, thereby improving the sorting efficiency.

[0049] The rest of the working principle and working process of this embodiment are consistent with those of embodiment 1 or embodiment 2.

[0050] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
