Description

Technical Field

[0001] The invention relates to the technical field of conveying equipment, and in particular to feeding and conveying equipment and a method applied to a plastic crusher. Background Art

[0002] Plastic crusher is mainly used to crush various plastic wastes, scraps, etc. The plastic material enters the crushing chamber through the feed port and is crushed into smaller particles under the shearing and impact of the high-speed rotating cutter, which is convenient for subsequent processing and reuse. The operation is relatively simple and the operating cost is not high. The feeding and conveying equipment of the plastic crusher is used to transport the plastic to be crushed into the plastic crusher. Common feeding and conveying equipment includes conveyor belts, screw conveyors and vibrating feeders.

[0003] During the recycling process, waste plastics are easily mixed with impurities such as stones and soil when stored in landfills or construction sites, and some mechanical parts use plastic wrapped metal, so waste plastics are mixed with stones or metals after recycling. If waste plastics are mixed with iron blocks, steel bars or stones, plastic crushers generally cannot crush them and may damage the machine, which in turn causes limitations.

[0004] To this end, we propose a feeding and conveying device and method for a plastic crusher. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a feeding and conveying device and method for a plastic crusher, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0006] To achieve the above object, the present invention provides the following technical solution: a feeding and conveying device applied to a plastic crusher, comprising:

[0007] A frame, a transmission frame, a vibration mechanism and an inclined plate; the transmission frame is fixedly connected to the frame, and a feed port and an outlet are respectively provided at both ends of the transmission frame; the inclined plate is fixedly connected to the transmission frame; the vibration mechanism is fixedly connected to the transmission frame, and is used to generate vibration on the inclined plate;

[0008] The inclined plate is provided with openings numbered one at even intervals; a storage frame is fixedly connected to the lower portion of the inclined plate; the upper end of the storage frame covers the outer side of the opening numbered one, and the lower end is rotatably connected to a rotating plate.

[0009] Preferably, the bottom of the transmission frame is rotatably connected to a rotating electric push rod; the output end of the rotating electric push rod is rotatably connected to a support block; a pressure sensor is fixedly connected to the support block; a lower pressure block is fixedly connected to the lower end of the rotating plate; the lower pressure block is slidably connected in the support block and contacts the pressure sensor.

[0010] A storage frame is arranged on the inclined plate, and waste plastics fill the storage frame. When stones or metals move to opening No. 1 on the inclined plate, the stones or metals sink to the bottom of the storage frame under the action of vibration. Therefore, the present invention can screen out stones or metals mixed in the waste plastics while conveying the waste plastics.

[0011] Preferably, a blocking plate is slidably connected to the lower end of the inclined plate, and a blocking electric push rod is fixedly connected to the lower end of the inclined plate; the output end of the blocking electric push rod is fixedly connected to the blocking plate, and the blocking plate can block the No. 1 opening under the push of the blocking electric push rod.

[0012] Preferably, an arc-shaped collecting plate is fixedly connected in the transmission frame; a second opening is opened at the lower end of the arc-shaped collecting plate; a magnetic screening plate is fixedly connected below the arc-shaped collecting plate; and a magnetic screening coil is fixedly connected to the back of the magnetic screening plate.

[0013] An arc-shaped collecting plate is arranged in the transmission frame, so that after the stones or metals discharged from the storage frame fall onto the arc-shaped collecting plate, they are discharged from the second opening along the magnetic screening plate. Since the magnetic force generated by the magnetic screening coil has no effect on the stones, the stones slide and fall normally along the magnetic screening plate; the magnetic force generated by the magnetic screening coil slows down the movement speed of the metal and the plastic wrapped by the metal, so that the distance moved by the metal or the plastic wrapped by the metal during the falling process is less than that of the stones. Therefore, the present invention screens out the stones and the metal or the plastic wrapped by the metal.

[0014] Preferably, a sliding frame is fixedly connected to the storage frame; the sliding frame is connected to the storage frame, a spacer block is slidably connected to the storage frame, and a spacer electric push rod is fixedly connected to the storage frame; the output end of the spacer electric push rod is fixedly connected to the spacer block.

[0015] Preferably, the upper end of the spacer block is inclined; a blocking plate is rotatably connected to the sliding frame; and the lower end of the blocking plate contacts and fits with the inclined end face of the spacer block.

[0016] Preferably, an acceleration shaft is rotatably connected to the transmission frame, and an acceleration motor is fixedly connected to the transmission frame; the output end of the acceleration motor is fixedly connected to the acceleration shaft; acceleration plates are evenly fixedly connected to the acceleration shaft; the acceleration shaft is arranged at the No. 2 opening on the arc-shaped collecting plate.

[0017] An acceleration shaft and an acceleration plate are arranged on the transmission frame, and the acceleration motor drives the acceleration shaft and the acceleration plate to rotate, so that the acceleration plate pushes the passing stone or metal, so that the metal or the plastic wrapped in the metal is affected by the magnetic force, thereby increasing the speed difference between the stone and the metal, thereby preventing the stone from sliding slowly and the difference in falling speed with the metal is not obvious after falling.

[0018] A feeding and conveying method applied to a plastic crusher, the method is applicable to the above-mentioned feeding and conveying equipment applied to the plastic crusher, and the steps of the method are as follows:

[0019] S1, waste plastics move along the inclined plate and enter the storage frame through opening No. 1. The stones or metals mixed in the waste plastics have high density and sink to the bottom of the storage frame. The force acting on the rotating plate is transmitted to the pressure sensor;

[0020] S2. As the number of stones or metals in the storage frame increases, the pressure on the pressure sensor increases. When the storage frame is full of stones or metals, the pressure reaches the threshold, the electric push rod is turned to drive the rotating plate to rotate, and the stones or metals are discharged and fall onto the arc-shaped collection plate;

[0021] S3. Stones or metals pass through the No. 2 opening and move along the magnetic screening plate. The magnetic force generated by the magnetic screening coils on the magnetic screening plate slows down the movement of the metal, so that the stones are separated from the metal after falling.

[0022] Beneficial effects of the present invention:

[0023] 1. The present invention arranges a storage frame on an inclined plate, and the waste plastics fill the storage frame. When stones or metals move to opening No. 1 on the inclined plate, the stones or metals sink to the bottom of the storage frame under the action of vibration. Thus, the present invention can screen out stones or metals mixed in the waste plastics while conveying the waste plastics.

[0024] 2. The present invention arranges an arc-shaped collecting plate in the transmission frame so that the stones or metals discharged from the storage frame fall onto the arc-shaped collecting plate and are then discharged from the second opening along the magnetic screening plate. The magnetic force generated by the magnetic screening coil slows down the movement speed of the metal and the plastic wrapped in the metal, so that the distance moved by the metal or the plastic wrapped in the metal during the falling process is smaller than that of the stones. Therefore, the present invention screens out the stones and the metal or the plastic wrapped in the metal. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0032] Embodiment 1: Refer to the attached specification Figure 1 , 2 , 3, 4 and 5, feeding and conveying equipment used for plastic crushers, including:

[0033] A frame, a transmission frame 1, a vibration mechanism 11 and an inclined plate 12; the transmission frame 1 is fixedly connected to the frame, and a feed port 13 and a discharge port 14 are respectively provided at both ends of the transmission frame 1; the inclined plate 12 is fixedly connected to the transmission frame 1; the vibration mechanism 11 is fixedly connected to the transmission frame 1, and is used to generate vibration on the inclined plate 12;

[0034] The inclined plate 12 is provided with openings 15 at even intervals. A storage frame 16 is fixedly connected to the lower portion of the inclined plate 12. The upper end of the storage frame 16 covers the outer side of the opening 15, and the lower end is rotatably connected to a rotating plate 17.

[0035] In the present invention, a rotating electric push rod 18 is rotatably connected to the bottom of the transmission frame 1; the output end of the rotating electric push rod 18 is rotatably connected to a support block 19; a pressure sensor 2 is fixedly connected to the support block 19; a lower pressure block 21 is fixedly connected to the lower end of the rotating plate 17; the lower pressure block 21 is slidably connected in the support block 19 and contacts the pressure sensor 2.

[0036] In the present invention, the waste plastic enters the transmission frame 1 from the feed port 13, and the vibration mechanism 11 operates to make the inclined plate 12 vibrate. After the waste plastic falls on the inclined plate 12, it moves along the inclined surface of the inclined plate 12 under the action of vibration. When the waste plastic moves to the opening position on the inclined plate 12, the waste plastic enters the storage frame 16 from the opening on the inclined plate 12, and moves along the inclined plate 12 again after filling the storage frame 16, until it is discharged from the discharge port 14.

[0037] The stones or metals mixed in the waste plastics enter the storage frame 16 together with the waste plastics. Since the storage frame 16 vibrates together with the inclined plate 12, the stones and metals with a density greater than that of the waste plastics sink to the bottom of the storage frame 16. When the stones or metals in the storage frame 16 accumulate to a certain amount, the force acting on the rotating plate 17 in the storage frame 16 increases to a predetermined value. After the pressure sensor 2 detects it, the electric push rod 18 is rotated to pull the rotating plate 17 to rotate, so that the stones or metals in the storage frame 16 are discharged from the storage frame 16.

[0038] The present invention sets a storage frame 16 on the inclined plate 12, and the waste plastics fill the storage frame 16. When stones or metals move to the No. 1 opening 15 on the inclined plate 12, the stones or metals sink to the bottom of the storage frame 16 under the action of vibration. Therefore, the present invention can screen out stones or metals mixed in the waste plastics while conveying the waste plastics.

[0039] Refer to the instruction manual Figure 2 and 4 In the present invention, the lower end of the inclined plate 12 is slidably connected to the blocking plate 3, and the lower end of the inclined plate 12 is fixedly connected to the blocking electric push rod 31; the output end of the blocking electric push rod 31 is fixedly connected to the blocking plate 3, and the blocking plate 3 can block the No. 1 opening 15 under the push of the blocking electric push rod 31.

[0040] In the present invention, an arc-shaped collecting plate 4 is fixedly connected inside the transmission frame 1; a second opening 41 is opened at the lower end of the arc-shaped collecting plate 4; a magnetic screening plate 42 is fixedly connected below the arc-shaped collecting plate 4; and a magnetic screening coil 43 is fixedly connected to the back of the magnetic screening plate 42.

[0041] In the present invention, a blocking plate 3 is arranged on the inclined plate 12. When the amount of stones or metals in the storage frame 16 reaches the amount to be discharged, the blocking electric push rod 31 pushes the blocking plate 3 to block the No. 1 opening 15. At this time, the waste plastics on the inclined plate 12 cannot enter the corresponding storage frame through the No. 1 opening 15. Therefore, when the storage frame discharges the stones or metals inside, the waste plastics on the inclined plate 12 will not enter the storage frame and will be discharged together with the stones or metals.

[0042] In the present invention, an arc-shaped collecting plate 4 is arranged in the transmission frame 1, so that after the stones or metals discharged from the storage frame 16 fall onto the arc-shaped collecting plate 4, they are discharged from the second opening 41 along the magnetic screening plate 42. Since the magnetic force generated by the magnetic screening coil 43 has no effect on the stones, the stones slide and fall normally along the magnetic screening plate 42; the magnetic force generated by the magnetic screening coil 43 slows down the movement speed of the metal and the plastic wrapped in the metal, so that the distance moved by the metal or the plastic wrapped in the metal during the falling process is less than that of the stones. Therefore, the present invention screens out the stones and the metal or the plastic wrapped in the metal.

[0043] Embodiment 2: Based on Embodiment 1, refer to the attached Figure 4 In the present invention, a sliding frame 5 is fixedly connected to the storage frame 16; the sliding frame 5 is connected to the storage frame 16, a spacer block 51 is slidably connected to the storage frame 16, and a spacer electric push rod 52 is fixedly connected to the storage frame 16; the output end of the spacer electric push rod 52 is fixedly connected to the spacer block 51.

[0044] In the present invention, the upper end of the spacer block 51 is inclined; the blocking plate 53 is rotatably connected to the sliding frame 5; the lower end of the blocking plate 53 contacts and fits with the inclined end surface of the spacer block 51.

[0045] In the present invention, an acceleration shaft 6 is rotatably connected to the transmission frame 1, and an acceleration motor 61 is fixedly connected to the transmission frame 1; the output end of the acceleration motor 61 is fixedly connected to the acceleration shaft 6; the acceleration plate 62 is evenly fixedly connected to the acceleration shaft 6; the acceleration shaft 6 is arranged at the No. 2 opening 41 on the arc-shaped collecting plate 4.

[0046] In the present invention, a sliding frame 5 and a spacer block 51 are arranged on the side of the storage frame 16, and the spacer electric push rod 52 pushes the spacer block 51 to extend into the storage frame 16. The volume of the spacer block 51 extending into different storage frames 16 is different, so that the volume of stones or metals stored in different storage frames 16 is different, so that the storage frame 16 discharges stones or metals at different times, and the situation that the No. 1 opening 15 is closed at the same time and the storage frame 16 discharges stones or metals will not occur, thereby preventing the situation that the No. 1 opening 15 is closed at the same time and the stones on the inclined plate 12 enter the plastic crusher from the discharge port 14 along the inclined plate 12;

[0047] In the present invention, the upper end of the spacer block 51 is set to be inclined to prevent stones from falling onto the spacer block 51 or the spacer block 51 supports the stones so that the stones do not fall. The blocking plate 53 is rotatably connected to the storage frame 16 through a torsion spring, so that the blocking plate 53 blocks the gap between the upper end of the spacer block 51 and the storage frame 16 to prevent stones from entering.

[0048] In the present invention, an acceleration shaft 6 and an acceleration plate 62 are arranged on the transmission frame 1, and the acceleration motor 61 drives the acceleration shaft 6 and the acceleration plate 62 to rotate, so that the acceleration plate 62 pushes the passing stone or metal, so that the metal or the plastic wrapped in the metal is affected by the magnetic force, thereby increasing the speed difference between the stone and the metal, thereby preventing the stone from sliding slowly and the difference between the falling speed of the stone and the falling speed of the metal is not obvious after falling.

[0049] Embodiment 3: A feeding and conveying method applied to a plastic crusher. The method is applicable to the above-mentioned feeding and conveying equipment applied to a plastic crusher. The steps of the method are as follows:

[0050] S1, waste plastics move along the inclined plate 12 and enter the storage frame 16 through the No. 1 opening 15. The stones or metals mixed in the waste plastics have a large density and sink to the bottom of the storage frame 16. The force exerted on the rotating plate 17 is transmitted to the pressure sensor 2;

[0051] S2. As the number of stones or metals in the storage frame 16 increases, the pressure on the pressure sensor 2 increases. When the storage frame 16 is full of stones or metals, the pressure reaches a threshold value, the electric push rod 18 is rotated to drive the rotating plate 17 to rotate, and the stones or metals are discharged and fall onto the arc-shaped collecting plate 4.

[0052] S3, the stone or metal passes through the second opening 41 and moves along the magnetic screening plate 42. The magnetic force generated by the magnetic screening coil 43 on the magnetic screening plate 42 slows down the movement of the metal, so that the stone is separated from the metal after falling.
