DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] To solve the technical problem of how the device screens the resin, please refer to Figure 1-Figure 4 , this embodiment provides the following technical solutions:

[0026] A screening device for resin processing comprises a screening box 1, a cleaning mechanism 2 and a cleaning mechanism 3. A vibration motor 11 is installed on the surface of the screening box 1. The bottom of the screening box 1 is connected to a bottom plate 13 through a spring 12. A feed port 14 is provided at the top of the screening box 1. A cover plate 141 is provided at the upper end of the feed port 14. A screen 15 is installed inside the screening box 1.

[0027] A partition 17 is provided at the upper end of the screen 15 in the screening box 1. The top of the partition 17 is arranged in an angular shape. The left and right ends of the partition 17 are symmetrically inclined downward and a plurality of first guide plates 171 are provided. Second guide plates 18 are equidistantly provided on the inner wall of the screening box 1 in the opposite direction of the first guide plates 171.

[0028] Specifically, when the resin is put into the screening box 1 through the feed port 14, it is guided by the angular structure on the top of the partition 17, slides to both sides and falls on the first guide plate 171 and the second guide plate 18 in turn. Through the cooperation of the first guide plate 171 and the second guide plate 18, the dust and impurities mixed in the resin are lifted up. Since the mass of the resin is greater than the impurities and dust, the resin raw material continues to fall and falls on the screen 15 to be screened, while the dust and impurities remain in the air and are discharged by the impurity removal mechanism 2.

[0029] It should be noted that during screening, the vibration motor 11 is turned on, and the vibration motor 11 drives the screening box 1 to vibrate up and down. At this time, the spring 12 repeatedly expands and contracts, driving the resin raw material inside the screening box 1 to vibrate continuously, thereby promoting the speed at which the resin slides through the first guide plate 171 and the second guide plate 18, and also promoting the speed at which the resin passes through the screen 15, thereby improving the screening effect.

[0030] To solve the technical problem of how the device can prevent environmental pollution, please refer to Figure 1-Figure 2 , this embodiment provides the following technical solutions:

[0031] The impurity removal mechanism 2 includes a collecting pipe 21, an air duct 22 and a cleaning box 23. There are two collecting pipes 21 and they are symmetrically arranged on the left and right sides of the feed port 14. A filter screen 211 is installed at the connection between the collecting pipe 21 and the screening box 1. An exhaust fan 212 is installed in the collecting pipe 21. The collecting pipe 21 is sealed and connected to the cleaning box 23 through the air duct 22, and the cleaning box 23 is fixed to the surface of the screening box 1.

[0032] It should be noted that the cleaning box 23 is filled with water, and the filter screen 211 is provided to prevent the resin raw material in the screening box 1 from being sucked out and to protect the exhaust fan 212 .

[0033] Specifically, when impurities and dust inside the resin are raised, the cover plate 141 can be set to prevent dust and impurities from overflowing from the feed port 14. At this time, the exhaust fan 212 is started, and the exhaust fan 212 sucks out the impurities and dust and introduces them into the cleaning box 23 through the air duct 22. Since the cleaning box 23 is filled with water, the impurities and dust can combine with the water to prevent secondary dust, improve environmental protection, and provide protection for the health of the operator.

[0034] To solve the technical problem of how to avoid clogging of the sieve holes, please refer to Figure 3-Figure 4 , this embodiment provides the following technical solutions:

[0035] The cleaning mechanism 3 includes a bidirectional screw 31, a servo motor 32, a threaded sleeve 33 and a cleaning roller 34. One end of the bidirectional screw 31 is connected to the servo motor 32. There are two bidirectional screws 31 and two servo motors 32, which are symmetrically arranged front to back. The front and rear bidirectional screws 31 are connected to the cleaning roller 34 through the threaded sleeve 33. There are two cleaning rollers 34 and the bottom is in contact with the screen 15. The screening box 1 is provided with a chip outlet 16 at the left and right ends of the screen 15, and a sliding door 161 is slidably connected to the chip outlet 16.

[0036] It should be noted that the two servo motors 32 are of exactly the same model, and are located just below the partition 17 when the cleaning roller 34 does not need to be cleaned.

[0037] Specifically, when the mesh 15 is clogged after being used for a long time, the two servo motors 32 are started to make the two bidirectional screws 31 rotate synchronously, and the two cleaning rollers 34 are driven to move to both sides through the threaded sleeve 33 to clean the surface of the mesh 15 and clear the deposits inside the mesh. Then the sliding door 161 is lifted upwards, and the deposits are swept out from the chip outlet 16 under the sweeping of the cleaning roller 34, so that the mesh 15 is cleaned.

[0038] Working principle: When using the screening device for resin processing, first open the cover 141, pour the resin raw material into the feed port 14, and then close the cover 141. At this time, the raw material slides to both sides under the guidance of the angular structure on the top of the partition 17, and passes through the first guide plate 171 and the second guide plate 18 in turn. Through the cooperation of the first guide plate 171 and the second guide plate 18, the dust and impurities mixed in the resin are raised. At this time, start the exhaust fan 212 to suck out the impurities and dust and introduce them into the cleaning box 23, while the resin continues to fall and falls on the screen 15. Under the vibration of the vibration motor 11, it quickly passes through the screen 15 to achieve screening.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
