[0003] Among them, for Figure 1 and Figure 2 For the zipper head assembly 400 shown, its loading is also inseparable from the use of a vibrating screening plate, so that the use of the vibrating screening plate can realize the purpose of sorting and conveying the disordered zipper head assembly 400 to achieve the purpose of loading.

[0004] However, in the process of sorting and conveying the zipper head components 400 by the existing vibration screening disk, the vibration screening disk cannot ensure that the position of each sorted and conveyed zipper head component 400 is in a normal orientation, so that the zipper head components 400 with normal orientation and those with abnormal orientation are mixed together for loading, thereby affecting the subsequent use of the zipper head components 400.

[0005] Therefore, there is an urgent need for a material removal and discharging mechanism of a vibrating screening plate for a zipper head assembly and a vibrating screening plate for a zipper head assembly having the mechanism to overcome one or more of the above-mentioned defects.

Detailed implementation manners

[0036] In order to elaborate in detail the technical content and structural features of the present utility model, the following further explanations are provided in combination with the implementation manners and accompanied by the drawings.

[0037] Please refer to Figure 4 , the vibrating screening tray 1000 of the zipper head assembly of the present utility model is used for vibrating and sorting the disordered zipper head assemblies 400 for conveying, so as to remove the zipper head assemblies 400 abnormally supported on the outer conveying rail 300 (mentioned below), and to discharge the zipper head assemblies 400 normally supported on the outer conveying rail 300 outward, so as to ensure that the position and orientation of each discharged zipper head assembly 400 are normal, and to avoid the situation where the discharged zipper head assemblies 400 have abnormal position and orientation. Supplementary note: The zipper head assembly 400 normally supported on the outer conveying rail 300 means that in the zipper head assembly 400, its chain head 410 and pull handle 420 are both placed vertically, and the front surface 413 of the chain head 410 faces forward and the rear surface 412 of the chain head 410 faces backward, and the state is shown in Figure 12 the figure shown. And the zipper head assembly 400 abnormally supported on the outer conveying rail 300 means that in the zipper head assembly 400, its chain head 410 and pull handle 420 are both placed horizontally, and the front surface 413 of the chain head 410 faces forward and the rear surface 412 of the chain head 410 faces backward, and the state is shown in Figure 15 the figure shown. It should be noted that although Figure 15 the shown pull handle 420 is placed horizontally. Of course, in the case where the chain head 410 is placed horizontally, even if the pull handle 420 is placed vertically, it still belongs to the situation where the zipper head assembly 400 is abnormally supported on the outer conveying rail 300, so it is not limited to Figure 15 the figure shown. In addition, in combination with Figures 1 to 3 , in the zipper head assembly 400, the front surface 413 of its chain head 410 is connected to the pull handle 420 by a connecting structure 414 to meet the need for the pull handle 420 to be movable relative to the chain head 410; in addition, through slots 411 penetrating up and down are formed on both left and right sides of the chain head 410 (see Figure 1 and Figure 2As shown in the figure, it is to meet the need for the slider assembly 400 to hang on the external feeding guide rail 300 or the discharging guide rail 20 and slide along the fabric seam 411. Since the slider assembly 400 is a well-known structure in the art, it will not be elaborated here.

[0038] Please refer to again Figure 4 , the vibrating screening plate 1000 of the slider assembly of the present utility model is used to remove the discharging mechanism 100 and the vibrating screening plate body 200 for sorting and conveying the disordered slider assemblies 400. An external feeding guide rail 300 for supporting the sorted sliding of the slider assembly 400 is externally connected to the vibrating screening plate body 200. That is to say, the external feeding guide rail 300 is used to support the slider assembly 400 and allow the slider assembly 400 to slide along the external feeding guide rail 300, and the sliding power can come from the vibration of the vibrating screening plate body 200. The removing and discharging mechanism 100 is assembled on the vibrating screening plate body 200, and the vibrating screening plate body 200 provides an assembly place and a supporting function for the removing and discharging mechanism 100. Optionally, in Figure 4 , as an example, the removing mechanism 100 is located outside the vibrating screening plate body 200, and the removing mechanism 100 is fixed at the top side wall of the vibrating screening plate body 200. Obviously, according to actual needs, the position between the removing mechanism 100 and the vibrating screening plate body 200 can also be other, so it is not limited by Figure 4 shown. Since the specific structure and working principle of the vibrating screening plate body 200 are well-known in the art, it will not be elaborated here.

[0039] Combined with Figure 5 , Figure 9 and Figure 10 , the removing and discharging mechanism 100 includes a mechanism frame body 10 and a discharging guide rail 20. The mechanism frame body 10 has a guiding channel 11 for guiding the slider assembly 400 sliding along the external feeding guide rail 300. The guiding channel 11 penetrates the mechanism frame body 10 in the left-right direction of the mechanism frame body 10. The state is shown in Figure 11 . The left end 310 of the external feeding guide rail 300 extends into the guiding channel 11. Optionally, the left end 310 of the external feeding guide rail 300 extends into the guiding channel 11 from the right side of the mechanism frame body 10 to meet the need for the slider assembly 400 to slide into the guiding channel 11 along the external feeding guide rail 300. The right end 21 of the discharging guide rail 20 extends into the guiding channel 11. Optionally, the right end 21 of the discharging guide rail 20 extends into the guiding channel 11 from the left side of the mechanism frame body 10. The left end 310 of the external feeding guide rail 300 and the right end 21 of the discharging guide rail 20 are arranged opposite to each other. Optionally, in Figure 5 and Figure 7In this case, as an example, the right end 21 of the discharge guide rail 20 is aligned with the left end 310 of the external feeding guide rail 300 in the left-right direction of the mechanism frame 10 to ensure that the cloth seam 411 of the zipper head assembly 400 normally supported on the external feeding guide rail 300 can be accurately aligned with the right end 21 of the discharge guide rail 20 after the zipper head assembly 400 slides off the left end 310 of the external feeding guide rail 300, so as to ensure that the zipper head assembly 400 can smoothly slide along the discharge guide rail 20; obviously, according to actual needs, there may also be a certain range of controllable deviation between the right end 21 of the discharge guide rail 20 and the left end 310 of the external feeding guide rail 300 in the left-right direction of the mechanism frame 10. The deviation amount is flexibly adjusted according to actual needs, as long as it is ensured that the zipper head assembly 400 normally supported on the external feeding guide rail 300 can be hooked on the discharge guide rail 20 and slide along the discharge guide rail 20.

[0040] There is also a certain interval between the left end 310 of the external feeding guide rail 300 and the right end 21 of the discharge guide rail 20, as shown by the reference numeral P1 in Figure 6 to meet the need for a disconnection fit between the right end 21 of the discharge guide rail 20 and the left end 310 of the external feeding guide rail 300. The state is shown in Figure 5 and Figure 6 as shown. There are certain gaps between the top 23 of the discharge guide rail 20 and the top 320 of the external feeding guide rail 300 and the mechanism frame 10 to prevent the mechanism frame 10 from obstructing the zipper head assembly 400 sliding along the external feeding guide rail 300 and the discharge guide rail 20, so as to meet the need for the zipper head assembly 400 to slide on the external feeding guide rail 300 and the discharge guide rail 20.

[0041] There is also an ejection opening 12 on the mechanism frame 10 for the zipper head assembly 400 abnormally supported on the external feeding guide rail 300 to slide off and be ejected. The ejection opening 12 is offset downward by a preset distance relative to the top 111 of the guiding channel 11. The state is shown in Figure 11 as shown, and the ejection opening 12 also corresponds to the gap 30 between the external feeding guide rail 300 and the discharge guide rail 20 to meet the need for the zipper head assembly 400 abnormally supported on the external feeding guide rail 300 to fall from the ejection opening 12. It should be noted that the downward offset of the ejection opening 12 relative to the top 111 of the guiding channel 11 by a preset distance is determined by the width dimension W of the chain head 410 to ensure that the size of the ejection opening 12 is larger than the width dimension W of the chain head 410 and smaller than the length dimension L of the chain head 410. More specifically, as follows:

[0042] As Figure 5As shown, as an example, the ejection opening 12 also exposes the left end 310 of the outer conveying guide rail 300 and the right end 21 of the discharging guide rail 20 from the front of the mechanism frame 10, so as to increase the size of the ejection opening 12 in the left-right direction of the mechanism frame 10, and thus can more reliably ensure that the slider assembly 400 abnormally supported on the outer conveying guide rail 300 falls from the ejection opening 12. In addition, the left end 22 of the discharging guide rail 20 is located outside the guiding channel 11, so that the discharging guide rail 20 extends out of the mechanism frame 10, thereby making it more convenient to grasp the slider assembly 400 being discharged. In addition, in Figures 5 to 8 As an example, the outer conveying guide rail 300 is a sheet-shaped curved guide rail, so that the outer conveying guide rail 300 can better receive the slider assembly 400 sorted and conveyed by the vibrating screening disk body 200; the discharging guide rail 20 is a sheet-shaped straight guide rail to meet the need for the slider assembly 400 to be discharged in a straight line; the right end 21 of the discharging guide rail 20 is an inclined structure 23 arranged obliquely upward from right to left. The purpose of such a design is that after the slider assembly 400 normally supported on the outer conveying guide rail 300 slides off the left end 310 of the outer conveying guide rail 300, the slider assembly 400 gradually hangs on the right end 21 of the discharging guide rail 20 by virtue of its cloth seam 411, thereby further improving the accuracy and reliability of the slider assembly 400 hanging on the right end 21 of the discharging guide rail 20.

[0043] Combined with Figures 5 to 11 As an example, the mechanism frame 10 includes a lower limiting and guiding structure 10a for defining the lower channel wall 11a of the guiding channel 11, a rear limiting and guiding structure 10b for defining the rear channel wall 11b of the guiding channel 11, an upper limiting and guiding structure 10c for defining the upper channel wall 11c of the guiding channel 11, and a front limiting and guiding structure 10d for defining the front channel wall 11d of the guiding channel 11. The front limiting and guiding structure 10d protrudes downward from the upper limiting and guiding structure 10c and is arranged at intervals from top to bottom with the lower limiting and guiding structure 10a. A partial gap 10e between the front limiting and guiding structure 10d and the lower limiting and guiding structure 10a forms the ejection opening 12, that is, the ejection opening 12 is formed by a part of the gap 10e, rather than all parts of the gap 10e. Specifically, in Figure 11In the embodiment, as an example, the front position-limiting guide structure 10d is arranged forwardly offset relative to the lower position-limiting guide structure 10a, so that there is no obstruction at the position directly below the front position-limiting guide structure 10d, so that it is more convenient for the zipper head assembly 400 supported on the external delivery guide rail 300 in an abnormal state to fall downward from the removal opening 12; in addition, the lower position-limiting guide structure 10a is provided with an inclined structure 10a1 inclined from top to bottom and forward at the position for defining the removal opening 12, so that the smoothness of the zipper head assembly 400 in an abnormal state to fall downward from the removal opening 12 can be further improved. In addition, the lower position-limiting guide structure 10a, the rear position-limiting guide structure 10b, the upper position-limiting guide structure 10c and the front position-limiting guide structure 10d are each a long strip-shaped plate extending in the left-right direction of the mechanism frame 10, so as to simplify the structure of the mechanism frame 10 and also meet the requirement that the guide channel 11 has a certain length.

[0044] like Figure 10 As shown, as an example, the right end of the rear limiting guide structure 10b is a rearward curved raised end 10b1 that is bent backward, the right end of the upper limiting guide structure 10c is an upward curved raised end 10c1 that is bent upward, and the right end of the front limiting guide structure 10d is a front curved raised end 10d1 that is bent forward. This design can increase the size of the guide channel 11 on the right side of the mechanism frame 10, thereby making it easier for the zipper head assembly 400 to enter the guide channel 11 along the external delivery guide rail 300.

[0045] Combination Figures 4 to 10 As an example, the rear limit guide structure 10b is fixed on the vibration screening plate body 10, and the upper limit guide structure 10c is assembled on the rear limit guide structure 10b in a manner that the position can be adjusted up and down. Optionally, as an example, the upper limit guide structure 10c is assembled on the rear limit guide structure 10b in a manner that the position can be adjusted up and down. Figures 5 to 9 In the embodiment, the upper limit guide structure 10c is provided with an upper and lower adjustment long hole 15, and an adjustment screw 16 passes through the upper and lower adjustment long hole 15 and is threadedly connected to the rear limit guide structure 10b, so that the position of the upper limit guide structure 10c can be adjusted and the position after adjustment can be fixed by screwing the adjustment screw 16; obviously, according to actual needs, there are other ways to realize that the upper limit guide structure 10c is assembled on the rear limit guide structure 10b in a position that can be adjusted up and down, so it is not mentioned here. Figures 5 to 9 The upper limit guide structure 10c is adjusted up and down to accommodate the use requirements of the chain head 410 with different lengths L.

[0046] Recombination Figures 4 to 10As an example, the front limit guide structure 10d is assembled on the vibration screening plate body 200 so that the position can be adjusted up and down and forward and backward to meet the use requirements of the chain head 410 with different width dimensions L and thickness dimensions. Figures 5 to 9 As an example, the front position limiting guide structure 10d is adjusted up and down in the following ways: the front position limiting guide structure 10d is provided with an up and down adjustment slot 13, an adjustment screw 14 passes through the up and down adjustment slot 13 and is threadedly connected to the mounting block 210 provided on the vibration screening disk body 200, so as to adjust the position of the front position limiting guide structure 10d and fix the adjusted position by screwing the adjustment screw 14; obviously, according to actual needs, there are other ways to realize that the front position limiting guide structure 10d is assembled on the vibration screening disk body 200 in a position that can be adjusted up and down, so it is not mentioned here. Figures 5 to 9 in addition, for the front limit guide structure 10d was adjusted to the position of the front and rear assembly on the vibration screening plate body 200 of the implementation, the adjustment of the long slot 13 and the adjustment screw 14 can also be used in a manner, so it is not repeated here.

[0047] In summary, by adjusting the positions of the above components, the up-and-down dimensions and / or the front-and-back dimensions of the guide channel 11 are arranged to be adjustable, thereby being compatible with the use requirements of zipper head assemblies 400 of different specifications.

[0048] like Figures 6 to 9 As shown, as an example, the lower position limiting guiding structure 10a includes a front lower position limiting guiding structure 10a2 and a rear lower position limiting guiding structure 10a3 which are arranged side by side in the front-to-back direction. The delivery guide rail 300 and the discharge guide rail 20 are sandwiched between the front lower limit guide structure 10a2 and the rear lower limit guide structure 10a3. A fastener 10f is inserted into the front lower limit guide structure 10a2, the discharge guide rail 20 and the rear lower limit guide structure 10a3 along the front-to-back direction of the mechanism frame 10. The fastener 10f selectively locks or releases the front lower limit guide structure 10a2, the discharge guide rail 20 and the rear lower limit guide structure 10a3. When the fastener 10f is released and locked, the discharge guide rail 20 can be adjusted in the up-down direction to accommodate the use requirements of zipper head assemblies 400 with different specifications. It can also be adjusted for the same zipper head assembly 400 to ensure the reliability of the alignment of the cloth seam 411 with the discharge guide rail 20. Specifically, Figure 7 and Figure 8 As an example, the discharge guide rail 20 is further provided with upper and lower long slots 24, and the fastener 10f passes through the discharge guide rail 20 from the upper and lower long slots 24, so that the design is more convenient for the up and down adjustment of the discharge guide rail 20. It should be noted that the fastener 10f is a screw, and obviously, it can also be other structures, so it is not limited to this.

[0049] Compared with the prior art, by means of "the left end 310 of the external delivery guide rail 300 extends into the guiding channel 11, the right end 21 of the discharging guide rail 20 extends into the guiding channel 11, the left end 310 of the external delivery guide rail 300 and the right end 21 of the discharging guide rail 20 are arranged opposite to each other with a certain interval, as indicated by the reference numeral P1 shown in Figure 6 ; the top 23 of the discharging guide rail 20 and the top 320 of the external delivery guide rail 300 (as shown in Figure 8 ) both have a certain gap with the mechanism frame 10" and "the mechanism frame 10 further has a rejection opening 12 for the zipper head assembly 400 abnormally supported on the external delivery guide rail 300 to slide off and be rejected. The rejection opening 12 is offset downward by a preset distance relative to the top 11 of the guiding channel 11 (the state is shown in Figure 11 ), and the rejection opening 12 also corresponds to the gap 30 between the external delivery guide rail 300 and the discharging guide rail 20". Such a design enables the zipper head assembly 400 normally supported on the external delivery guide rail 300 to continue to slide after sliding away from the left end 310 of the external delivery guide rail 300 under the guidance of the guiding channel 11. The continuously sliding zipper head assembly 400 then slides out on the discharging guide rail 20 by means of its cloth seam 411, thereby ensuring that the position and orientation of the discharged zipper head assembly 400 are normal and facilitating subsequent use; while the zipper head assembly 400 abnormally supported on the external delivery guide rail 300, after sliding away from the left end 310 of the external delivery guide rail 300, since the dimension of the zipper head assembly 400 abnormally supported on the external delivery guide rail 300 in the up-and-down direction (i.e., the width dimension W shown in Figure 3 ) is smaller than the dimension of the zipper head assembly 400 normally supported on the external delivery guide rail 300 in the up-and-down direction (i.e., the length dimension L shown in Figure 3 ), and combined with the design that "the rejection opening 12 is offset downward by a preset distance relative to the top 111 of the guiding channel 11", the zipper head assembly 400 abnormally supported on the external delivery guide rail 300 will fall from the rejection opening 12 after sliding away from the left end 310 of the external delivery guide rail 300. Therefore, the vibration screening tray for the zipper head assembly of the present utility model can ensure that the position and orientation of the discharged zipper head assembly 400 are normal and facilitate subsequent use with 100% certainty.

[0050] It should be noted that the direction indicated by the arrow A in the drawings is the direction from right to left of the mechanism frame 10, the direction indicated by the arrow B in the drawings is the direction from front to back of the mechanism frame 10, and the direction indicated by the arrow C in the drawings is the direction from bottom to top of the mechanism frame 10. In addition, the abnormal zipper head assembly 400 falls from the front of the mechanism frame 10 through the rejection opening 12 under the vibration of the vibration screening tray body 200, and the normal zipper head assembly 400 discharges outward along the discharging guide rail 20 under the vibration of the vibration screening tray body 200. Moreover, in Figure 10 , the horizontal line where the upper edge of the rejection opening 12 is located is shown as the center line; in Figure 6Among them, label C1 is the vertical center line where the right edge of the gap 10e between the front limiting and guiding structure 10d and the lower limiting and guiding structure 10a is located, label C2 is the vertical center line where the left edge of the gap 10e between the front limiting and guiding structure 10d and the lower limiting and guiding structure 10a is located, and the aforementioned P1 is less than the distance between C1 and C2.

[0051] The above-disclosed are only the preferred examples of the present utility model, and the scope of rights of the present utility model cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present utility model all fall within the scope covered by the present utility model.
