DETAILED DESCRIPTION
[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0027] Reference Figure 1-5 A plastic pellet conveying device comprises a conveying device body 1, the conveying device body 1 is provided with an inclined surface 10, a fixed surface 2 is provided below the conveying device body 1, a vibration motor 11 and an anti-smashing shield 3 are provided on the side wall of the conveying device body 1, the anti-smashing shield 3 is provided with an anti-wear and scratch-resistant layer 31, a dust storage box 5 and a spring bottom fixing plate 21 are provided on the fixed surface 2, a damping spring 41 is provided on the spring bottom fixing plate 21, and a spring motor 11 is provided on the side wall of the conveying device body 1. The spring top fixing plate 4, the dust storage box 5 is provided with a dust extraction pump 6 and a cleaning box door 51, the dust storage box 5 is connected with a main dust conveying pipe 7, the main dust conveying pipe 7 is connected with an auxiliary dust conveying pipe 71, and the auxiliary dust conveying pipe 71 is provided with a dust cleaning cover 8, the conveying device body 1, the damping spring 41, and the vibration motor 11 are the relevant component structures of the plastic pellet conveying device, which are the prior art. Some existing structures are not drawn and marked, and there is no need to repeat them. Among them, the conveying device body 1 is a commonly used vibrating feeding device.
[0028] The cleaning box door 51 is rotatably connected to the dust storage box 5 via a rotating shaft, and the cleaning box door 51 is also threadedly locked with the dust storage box 5 via preset bolts. When the dust storage box 5 is full of dust, the preset bolts are first rotated and removed, and then the cleaning box door 51 is rotated open to conveniently clean the dust inside the dust storage box 5.
[0029] In detail, a dust extraction head 61 is provided at the lower end of the dust extraction pump 6, and a dust filter 62 is provided inside the dust extraction head 61. The dust extraction head 61 is inserted into the top of the dust storage box 5, and the dust filter 62 is made of a polyester fiber PET filter element. The polyester fiber PET filter element material has very high strength, is non-deformable and durable, and can prevent dust from entering the dust extraction pump 6.
[0030] Furthermore, the top-view cross-section of the spring bottom fixing plate 21 is an I-shaped structure, and the upper and lower ends of the damping spring 41 are respectively fixed to the spring top fixing plate 4 and the spring bottom fixing plate 21. The I-shaped structure improves the structural connection stability between the left and right spring bottom fixing plates 21, thereby improving the effective damping stability of the entire conveying device body 1 through the four damping springs 41.
[0031] Furthermore, there are two auxiliary dust conveying pipes 71 connected to the main dust conveying pipe 7. The auxiliary dust conveying pipes 71 and the main dust conveying pipe 7 form a T-shaped structure as a whole, so that a single dust pump 6 can simultaneously suck away and clean the dust on the surface of the shock-absorbing springs 41 on both sides, thereby improving the utilization rate of the dust pump 6.
[0032] In more detail, the dust cover 8 is a diffuse horn cover structure as a whole and has a hollow cavity inside. The diffuse horn cover structure further increases the effective area of the dust cover 8 for sucking dust on the surface of the damping spring 41.
[0033] The end of the dust cover 8 facing the damping spring 41 is provided with a protective net 81 , which is made of a stainless steel filter, which is high in strength, high temperature resistant, weather resistant, durable, and impact resistant, and can prevent foreign objects, insects, and rodents from entering the auxiliary dust conveying pipe 71 .
[0034] In general, the side section of the anti-smash shield 3 is a bent structure, and the top view size of the anti-smash shield 3 is not less than the top view size of the vibration motor 11, so that the anti-smash shield 3 can fully and effectively protect the top of the vibration motor 11 from smashing.
[0035] Finally, the wear-resistant and scratch-resistant layer 31 is arranged on the top surface of the anti-smash shield 3. The wear-resistant and scratch-resistant layer 31 is a DLC diamond carbon film layer structure with a thickness of twenty to thirty microns. The DLC diamond carbon film layer has excellent wear-resistant and scratch-resistant properties, which greatly improves the service life of the anti-smash shield 3.
[0036] Working method: When conveying plastic pellets, first start the vibration motor 11 to drive the conveying device body 1 to vibrate up and down, and then put the plastic pellets onto the left end surface of the inclined surface 10. At this time, the plastic pellets will be fed from left to right along the up and down vibrating inclined surface 10, and finally fall into the barrel of the injection molding machine by gravity, realizing the vibration feeding of plastic pellets. This is the prior art.
[0037] After long-term use, dust will accumulate on the surface of the vibration-damping spring 41. At this time, the dust extraction pump 6 can be started, and suction force will appear in the dust cleaning cover 8, so that the dust accumulated on the surface of the vibration-damping spring 41 can be completely and effectively sucked away and cleaned. The cleaned dust will enter the dust storage box 5 through the auxiliary dust conveying pipe 71 and the main dust conveying pipe 7 for storage, thereby ensuring the vibration-damping performance of the vibration-damping spring 41 for the conveying device body 1, and further ensuring the normal vibration feeding work of the conveying device body 1 for the plastic particles.
[0038] In addition, by arranging an anti-smash shield 3 structure with a wear-resistant and scratch-resistant layer 31 above the vibration motor 11, the top of the vibration motor 11 is fully and effectively protected from being smashed, thereby preventing the top of the vibration motor 11 from being directly hit by external hard objects and causing damage and wear, thereby increasing the service life of the vibration motor 11.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
