[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention. Example

[0029] Reference Figure 1-Figure 5 As shown, a blanking device 4 of the present invention includes:

[0030] The housing 41 has a feed port and a discharge port on both sides thereof, the feed port being arranged at the upper end and the discharge port being arranged at the lower end, and connected to the barrel 11 of the discharge mechanism;

[0031] A column 48 is provided in the housing 41 along the extending direction of the feed port and the discharge port. The column 48 is detachably provided in the housing 41, and a material discharge channel is defined between the column 48 and the housing 41;

[0032] The adsorption mechanism includes: one or more magnetic members 43 sleeved on the column 48, and a ring 42 provided on the side of the magnetic member 43 close to the feed port, wherein the ring 42, the magnetic member 43 and the column 48 enclose a receiving space 47;

[0033] The buffer mechanism includes a sleeve 44 sleeved on the adsorption mechanism, and the sleeve 44 is provided with a plurality of through holes 45 .

[0034] The present invention describes a feeding device 4, when the material enters the shell 41 from the feed port and falls due to gravity, and the shell 41 is set at a sufficiently high height, the material continuously rolls in the feeding channel and passes through the sleeve 44, if there are magnetic impurities in the material, when passing through the adsorption mechanism, the magnetic member 43 generates an adsorption force on the magnetic debris, adsorbing the debris in the accommodation space 47 and the outer surface of the magnetic member 43, the magnetic debris enters the accommodation space 47 and is adsorbed by the magnetic member 43 and is not easy to fall, while normal wood-plastic material is easily shaken out by the vibration of the wood-plastic machine itself when entering the accommodation space 47, and when the material falls through the sleeve 44 of the buffer mechanism, the sleeve 44 is The hole 45 structure has a buffering effect on the material, reducing the impact of the material on the adsorbed magnetic debris. The through hole 45 can balance the pressure inside and outside the sleeve 44. When the material hits the sleeve 44, some air can enter and exit through the through hole 45 to prevent the material from being blocked from falling due to the air pressure difference. The buffered material continues to be output through the discharge port under the action of gravity. When the magnetic suction part adsorbs enough debris, the column 48 is removed to facilitate cleaning of the debris in the accommodating space 47 and the surface of the magnetic part 43, so that it is easy to use again. At the same time, the disassembly and replacement of columns 48 and adsorption mechanisms of different sizes can adapt to different material characteristics and discharge speeds, and ensure the adsorption rate of the adsorption mechanism for magnetic debris in the material.

[0035] Reference Figure 5 As shown, one side of the ring body 42 is sealed with the magnetic part 43, and a receiving opening is formed between the other side of the ring body 42 and the column 48. The receiving opening is connected to the receiving space 47. When the material enters the shell 41 from the feed port, it falls around the column 48 under the action of gravity. Since there is a receiving opening between the column 48 and the ring body 42, the magnetic debris can enter the receiving space 47 formed by the ring body 42, the magnetic part 43 and the column 48 through the receiving opening.

[0036] Reference Figure 3 As shown, the outer diameter of the magnetic element is slightly larger than or equal to the outer diameter of the ring body 42, and is equal to the inner diameter of the sleeve 44, so as to avoid the ring body 42 blocking the magnetic element. The ring body 42 is arranged above the magnetic element 43, so that the magnetic element and the ring body 42 are clamped in the sleeve 44, and the distance between the magnetic element and the material in the discharge channel is reduced, making it easier to adsorb the magnetic debris therein.

[0037] As shown in Reference 3, the first end of the sleeve 44 is provided with a first opening, and the first end of the sleeve 44 is the end thereof close to the feed port, and the second end of the sleeve 44 is provided with a closure 46, and the closure 46 is provided with a second opening, and the second end of the sleeve 44 is the end thereof close to the discharge port. The inner diameter of the first opening is greater than the inner diameter of the second opening, and the inner diameter of the first opening is slightly smaller than or equal to the outer diameter of the magnetic part 43, and the inner diameter of the second opening is slightly smaller than or equal to the outer diameter of the column 48, so that the sleeve 44 and the magnetic part are snapped together and can be directly plugged in and replaced. The closure 46 plays a role of limiting and bottom supporting. When disassembling, the sleeve 44 is pulled downward out of the column 48.

[0038] The through hole 45 passes through the peripheral side wall of the sleeve 44 to form a grid-like sleeve 44. The two sides of the through hole 45 are respectively connected to the discharge channel and the accommodating space 47. The material is slowed down by the grid-like sleeve 44, which makes it easier to adsorb magnetic debris and prevent dust.

[0039] In this embodiment, there are three groups of adsorption mechanisms, and the three groups of adsorption mechanisms are arranged at intervals to improve adsorption efficiency.

[0040] Reference Figure 2 As shown, the feed port movable cover of the shell 41 is provided with a cover 12, one end of the column 48 passes through the cover 12 and extends outside the shell 41, and the shell 41 is provided with a window 9. First remove the cover 12, and then take out the column 48. The sleeve 44 and the adsorption mechanism are taken out by the sleeve. After removing the sleeve 44 and the column 48, the magnetic debris can be cleaned and collected, and then reinstalled for reuse, and the adsorption strength can be guaranteed.

[0041] An exhaust pipe 8 is also provided on one side of the shell 41, and the exhaust pipe 8 is connected to the discharge channel. The ends of the exhaust pipe 8 are respectively connected to the exhaust fan 5 and the pulse air bag 6, and the filter bag 7 is fixed by a top fixing plate. A filter bag 7 is provided between the exhaust pipe 8 and the exhaust fan 5, and the filter bag 7 is connected by a fixing plate 13. The exhaust fan 5 and the exhaust pipe 8 are used to appropriately exhaust the shell 41, and the filter bag 7 is used to filter the material to prevent it from being adsorbed away, which can reduce debris dust and improve the granulation quality. The density of debris dust is generally much smaller than the density of magnetic debris. Therefore, the exhaust fan 5 mainly absorbs debris dust by adjusting the wind force. The density of magnetic debris is relatively large and cannot be separated from the material by exhaust while the material remains falling, and the debris dust is prevented from being mixed between the magnetic debris, which reduces the adsorption force of the magnetic part 43. In this embodiment, the magnetic part 43 is a strong magnet such as nylon iron boron. Example

[0042] Reference Figure 1 As shown, this embodiment discloses a wood molding pelletizer, including a feeding device 4 as described in Example 1.

[0043] The wood pelletizer 3 disclosed in this embodiment also includes: a main motor 1, a gearbox 2, a feeder 3, and a discharge mechanism. The gearbox 2 is connected to the output end of the main motor 1, and the output end of the gearbox 2 of the discharge mechanism is connected. The feed port of the housing 41 is connected to the output port of the feeder 3, and the discharge port of the housing 41 is connected to the discharge mechanism. When the main motor 1 is started, the power generated by it is transmitted to the gearbox 2 via the output shaft. The main motor 1 adjusts the transmission ratio through the gearbox 2, reducing the high speed and increasing the torque at the same time to meet the working requirements of the discharge mechanism. At the same time, the screw shaft motor in the feeder 3 is started, and the screw shaft begins to rotate. The wood-plastic raw material in the feed hopper of the feeder 3 moves from the discharge port of the feeder 3 to the feed port of the shell 41 of the discharge device 4 under the push of the spiral shaft. The wood-plastic raw material entering the feed port of the shell 41 of the discharge device 4 passes through the discharge channel between the column 48 and the shell 41 in the shell 41, where the magnetic debris is absorbed and driven by the discharge mechanism through the gear box 2. The discharge mechanism also includes a granulation mechanism. The spiral drive shaft in the discharge mechanism cooperates with the granulation sheet on the inner wall of the barrel 11 to cut the pellets when pushing the wood-plastic raw material, so as to be formed or granulated through the discharge mechanism.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
