DETAILED DESCRIPTION

[0032] 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 of 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.

[0033] It should be noted that if a directional indication is involved in the embodiments of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] In this specification, position terms such as "upper", "lower", "inner" and "outer" are defined according to the positions of the color sorter when it is normally used.

[0035] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0036] In view of the prior art, such as Fig.10 As shown, the transparent plate 20 of the color sorter observation window fits with the correction strip 30 after installation, which not only hinders observation, but also easily causes dust to accumulate and mold to grow in the gap between the transparent plate 20 and the correction strip 30. The utility model proposes a color sorter observation window structure to solve the above technical problems, and according to different optional forms of the utility model, other beneficial technical effects can also be obtained.

[0037] Reference Figures 1 to 4An observation window structure I of a color sorter according to the present invention is shown as an example, and includes a window frame 100 , a transparent plate 200 and a correction strip 300 .

[0038] The window frame 100 includes a first window frame plate 110, a second window frame plate 120, and a window 130. The first window frame plate 110 and the second window frame plate 120 may be substantially parallel to each other and spaced apart from each other. The window 130 is formed by a ring wall 140 extending between the first window frame plate 110 and the second window frame plate 120. The transparent plate 200 may be mounted on the first window frame plate 110 and cover the window 130. The correction bar 300 may be disposed on the second window frame plate 120 and span the window 130. The correction bar 300 has a correction slit 310 to calibrate the color sorter camera using a correction line passing through the correction slit 310. Since the window frame 100 adopts a double-layer plate, i.e., the first window frame plate 110 and the second window frame plate 120, and there is a sufficient distance between the first window frame plate 110 and the second window frame plate 120 due to being spaced apart from each other, the transparent plate 200 and the correction strip 300 respectively mounted thereon are spaced apart from each other, thereby reducing or eliminating the obstruction of the correction strip 300 to the observation field of the transparent plate 200, and at the same time, no dust will be deposited between the correction strip 300 and the transparent plate 200.

[0039] Figure 8 The color sorter II according to the present invention is exemplarily shown. The color sorter II includes a pair of the above-mentioned color sorter observation window structures I. During use, the calibration line is first pulled through the calibration bars 300 and the calibration slits 310 on the pair of color sorter observation window structures I, and then the color sorter camera is adjusted to align with the calibration line to calibrate the color sorter camera. After the calibration is completed, the calibration line is collected, and the transparent plate 200 covers the window 130 and is installed on the first window frame plate 110. It should be understood that the calibration line marks the position where the granular material passes when sliding down, and because different granular materials have different particle sizes, their sliding paths in the color sorter are different, so that the position where the color sorter camera needs to be aligned is also different. Therefore, in other embodiments, a plurality of calibration slits 310 may be provided on the calibration bar 300, which are respectively used to pull the calibration line to calibrate the color sorter camera when separating materials of different particle sizes.

[0040] In some embodiments of the color sorter according to the present invention, Figure 8 and Fig. 9As shown, the color sorter II also includes a frame body 400, and the frame body 400 includes a support rod 410. The support rod 410 can be inclined relative to the ground, and a pair of color sorter observation window structures I are installed on the support rod 410. Specifically, the window frame 100 of the color sorter observation window structure I may include a side wall 141 bent and extended from the edge of the first window frame plate 110 and / or the second window frame plate 120. Of course, the side wall 141 can also be a part of the ring wall 140. The side wall 141 is used to form a support for the window frame 100. The color sorter observation window structure I is installed on the upper side of the support rod 410 through the side wall 141, wherein the side of the transparent plate 200 away from the correction strip 300 faces the inside of the color sorter II. This can bring unique benefits, such as Fig. 9 As shown, at the observation window, the color sorter observation window structure I occupies the upper side of the support rod 410, and the side of the first window frame plate 110 facing the inside of the color sorter II is flush with the inner side of the support rod 410 facing the inside of the color sorter II, thereby avoiding the accumulation of dust on the upper side of the support rod 410. Fig.10 As shown, the window frame 10 of the color sorter observation window is a single-layer plate, and is therefore only suitable for installation on the outer side of the support rod 41 facing the outside of the color sorter II, so that the upper side of the support rod 41 at the observation window becomes a location where dust accumulates, which is prone to mold growth.

[0041] In some embodiments, the correction strip 300 may be mounted on the second window frame plate 120 by fasteners, as shown in FIG. Figure 1 , Figure 2 and Figure 4 , a pair of fasteners facing each other are provided on the second window frame plate 120. The correction strip 300 is provided with a first mounting hole 320 and a second mounting hole 330 at both ends, so that it can be installed on the second window frame plate 120 by a pair of fasteners. Specifically, the pair of fasteners can be configured as a first fastening screw 121 and a second fastening screw 122, respectively. The diameter of the first mounting hole 320 is smaller than the diameter of the head of the first fastening screw 121 and is greater than or equal to the diameter of the rod of the first fastening screw 121, and the diameter of the second mounting hole 330 is smaller than the diameter of the head of the second fastening screw 122 and is greater than or equal to the diameter of the rod of the second fastening screw 122. The rod of the first fastening screw 121 and the rod of the second fastening screw 122 can pass through the first mounting hole 320 and the second mounting hole 330, respectively, and the correction strip 300 can be installed on the second window frame plate 120 of the window frame 100 by screwing and pressing with their heads.

[0042] In some further embodiments, Figure 4As shown, the second mounting hole 330 is constructed as an oblong hole with one end extending to the edge of the correction bar 300 and open, and the second mounting hole 330 can be slidably connected with the fastener (the second fastening screw 122). In other words, the fastener can slide into or out of the second mounting hole 330 from the opening of the edge of the correction bar 300 at the second mounting hole 330, so as to be suitable for rotating the correction bar 300 around the fastener (the first fastening screw 121) passing through the first mounting hole 320. Figure 5 The calibration strip 300 is shown in the state where it is installed in place. Figure 5 , Figure 6 The figure shows the situation where the correction bar 300 rotates a certain angle. For example, initially, the correction bar 300 is fixed on the second window frame plate 120 and is located outside the window 130 by the first fastening screw 121, and the second fastening screw 122 is fixed on the second window frame plate 120; when the color sorter camera needs to be calibrated, the first fastening screw 121 and the second fastening screw 122 are loosened appropriately, and the correction bar 300 is rotated around the first fastening screw 121 until the second mounting hole 330 is aligned with the second fastening screw 122, and the correction bar 300 continues to rotate so that the rod of the second fastening screw 122 slides into the second mounting hole 330. After it is in place, the first fastening screw 121 and the second fastening screw 122 are tightened to install the correction bar 300 on the second window frame plate 120, and then the color sorter camera calibration operation can be performed. After the calibration is completed, loosen the first fastening screw 121 and the second fastening screw 122 appropriately, and turn the calibration bar 300 to rotate in the opposite direction around the first fastening screw 121, so that the second fastening screw 122 is disengaged from the second mounting hole 330, and the calibration bar 300 can be rotated out of the window 130, and then the transparent plate 200 is installed on the first window frame plate 110. In the subsequent use process, the calibration bar 300 can always be kept outside the window 130 to completely eliminate the obstruction of the field of vision observed through the transparent plate 200. Only when the color sorter camera needs to be calibrated, the calibration bar 300 is rotated and installed in the above manner.

[0043] In some embodiments, the first mounting hole 320 may include a fixing portion 321, a guide portion 322, and a connecting portion 323. The guide portion 322 is larger than the fixing portion 321 and is connected to the fixing portion 321 through the connecting portion 323. The fastener (first fastening screw 121) may slide from the guide portion 322 to the fixing portion 321 through the connecting portion 323. Specifically, the guide portion 322 is larger than the diameter of the head and the diameter of the rod of the first fastening screw 121. The first fastening screw 121 may pass through the guide portion 322 as a whole and slide from the rod of the first fastening screw 121 to the fixing portion 321 through the connecting portion 323. In this way, the disassembly and assembly of the correction bar 300 becomes simpler. The correction bar 300 can be disassembled and assembled by simply loosening the first fastening screw 121 and the second fastening screw 122. The correction bar 300 is suitable for being shared between multiple color sorters II.

[0044] In some embodiments, Figure 2 , Figure 3 and Figure 7 As shown, the first window frame plate 110 has an annular boss 111 to provide a mounting position for the transparent plate 200 on the first window frame plate 110. The annular boss 111 extends from the junction of the first window frame plate 110 and the annular wall 140 toward the window, and the transparent plate 200 can be abutted against and mounted on the surface of the annular boss 111 facing the second window frame plate 120. Since the annular boss 111 has a certain thickness, the transparent plate 200 and the annular boss 111 together define a layered space 131. The layered space 131 is in the form of a thin layer, has the same thickness as the annular boss 111, and is surrounded by the annular boss 111. In the color sorter II, the layered space 131 can be regarded as a portion of the transparent plate 200 separated from the window 130 and close to the interior of the color sorter II. The position where dust can accumulate can be reduced or eliminated by compressing or eliminating the layered space 131. Therefore, in other embodiments, such as Figure 3 and Figure 7 As shown, the transparent plate 200 may also have a protrusion 210, which is on the side of the transparent plate 200 away from the correction strip 300, that is, the side of the transparent plate 200 facing the inside of the color sorter II. The protrusion 210 extends through the first window frame plate 110 and is flush with the surface of the annular shoulder 111 away from the second window frame plate 120 / correction strip 300 (that is, the side of the annular shoulder 111 facing the inside of the color sorter II). The protrusion 210 at least fills part of the layered space 131. For example, in the color sorter II, the protrusion 210 at least fills the lower part of the layered space 131, and the protrusion 210 fits the annular shoulder 111 to eliminate the possible accumulation position of dust formed by the lower edge of the annular shoulder 111. In particular, the protrusion 210 may be provided with a chamfer 211. For example, in the color sorter II, when the protrusion 210 only fills the lower part of the layered space 131, a chamfer 211 is provided along the upper edge of the protrusion 210. In this way, dust and debris fall on the inclined surface of the chamfer 211 and are easy to slide down along the inclined surface, and are not easy to accumulate. It is also convenient for a dust cleaning brush with bristles perpendicular to the surface of the transparent plate 200 to clean. The transparent plate 200 can be made of a resin material to be suitable for processing the above-mentioned protrusion 210 and chamfer 211 on the transparent plate 200. Of course, in some embodiments, the protrusion 210 fills the entire layered space 131, thereby eliminating the layered space 131, and the peripheral side of the protrusion 210 fits with the annular boss 111, eliminating the position where dust and debris can fall, and can achieve better technical effects.

[0045] It should be understood that the transparent plate 200 can be detachably mounted on the first window frame plate 110, for example, it can be mounted on the annular boss 111 through the mounting member 111A. Figure 2As shown, the mounting member 111A can be configured as a mounting screw, a threaded hole 111B is provided on the annular boss 111, and a through hole 220 corresponding to the threaded hole 111B is provided on the edge of the transparent plate 200. The mounting member 111A configured as a mounting screw passes through the through hole 220 and is screwed into the threaded hole 111B. Finally, the mounting member 111A mounts the transparent plate 200 on the annular boss 111.

[0046] In some embodiments, Figure 1 As shown, in the direction from the second window frame plate 120 to the first window frame plate 110, the size of the window 130 gradually decreases, and the annular wall 140 / window 130 is in a gradually closing shape, so that on the color sorter II, it is convenient to install the transparent plate 200 on the first window frame plate 110 from the outside to the inside through the channel of the window 130 / annular wall 140.

[0047] It should be understood that the above description of the preferred embodiment is relatively detailed and cannot be regarded as limiting the scope of patent protection of the utility model. Under the enlightenment of the utility model, ordinary technicians in this field can also make substitutions or modifications without departing from the scope of protection of the claims of the utility model, which all fall within the scope of protection of the utility model. The scope of protection requested for the utility model shall be based on the attached claims.
