The following is a preferred embodiment of the present invention that solves the above technical problems.

[ first embodiment of an outer diameter sorting apparatus for buttons ]

Referring to fig. 1, the present invention provides an outer diameter sorting apparatus 100 for buttons, which includes: the device comprises a first feeding hopper 11, a first conveying device 12, an outer diameter sorting device 13, a vibrator 14 and a first machine frame 15.

The first frame 15 is used to carry the first feeding hopper 11, the first conveying device 12, the outer diameter sorting device 13 and the vibrator 14. The first frame 15 includes a housing 151, which is located above the body of the first frame 15, is in a rectangular parallelepiped shape, and is composed of two side shells and a bottom shell.

The upper end of the first feeding hopper 11 is a first feeding inlet 111, the lower end is a first feeding outlet 112, and the opening of the first feeding inlet 111 is larger than the opening of the first feeding outlet 112, and is substantially funnel-shaped, so that feeding is facilitated.

The first feeding device 12 comprises a first feeding hopper 121, which is shaped like a rectangular box, the front end of the first feeding hopper 121 is a first feeding inlet 121a, the rear end of the first feeding hopper 121 is a first feeding outlet 121b, the first feeding inlet 121a is located below the first feeding outlet 112, and the buttons flow from the first feeding hopper 11 to the first feeding device 12.

The outer diameter sorting means 13 is located below the first feeding outlet 121b and the buttons flow from the first feeding means 12 to the outer diameter sorting means 13. The outer diameter sorting device 13 includes a plurality of main screens 131 and a plurality of material distribution ports 132 (illustrated with two main screens 131 in the figure, and a plurality of main screens 131 can be set as required), the main screens 131 are disposed inside the housing 151, and are arranged in parallel from top to bottom, and have circular screen holes, and the outer diameter of the screen hole of the upper main screen 131 is larger than that of the lower main screen 131. The end of the main screen 131 far from the first material outlet 121b is the output end, and is lower than the end near the first material outlet 121b, so that the buttons can flow to the output end. The output end of one main screen 131 is connected with a corresponding distributing opening 132, and the distributing openings 132 are in different directions, so that buttons can be collected conveniently.

Two vibrators 14 are provided on the outer surface of the bottom casing for vibrating the first feeding hopper 11, the first feeding device 12 and the outer diameter sorting device 13 to flow the buttons to the next link.

The buttons are fed from a first feeding hopper 11 and then flow to a first feeding device 12 and then to an outer diameter sorting device 13 for sorting. The outer diameter sorting apparatus 13 is provided with a plurality of layers of main screens 131, and the outer diameter of the screen of the upper layer is larger than that of the screen of the lower layer, taking two layers of main screens 131 as an example. If the button outer diameter is larger than the mesh outer diameter of the upper main screen 131, it is left on the upper main screen 131, and if it is smaller than the outer diameter of the upper main screen 131, it falls through its mesh into the lower main screen 131. Since the output end of the main screen 131 is lower than the other end, the buttons remaining on the upper main screen 131 can flow out from the corresponding material dispensing ports 132 in the direction of inclination thereof. Similarly, if the outer diameter of the dropped button is larger than the outer diameter of the sieve hole of the lower main sieve 131, the button flows out from the material distributing port 132 corresponding to the lower main sieve 131; if the outer diameter of the sieve is smaller than the outer diameter of the sieve of the lower main sieve 131, the sieve falls into the bottom case from the sieve of the lower main sieve 131 and then flows out. If the multi-layer main screen 131 is arranged, buttons with different outer diameters can be sorted step by step from large to small, and the efficiency and the precision of sorting the outer diameters of the buttons are improved.

The first material conveying outlet 121b is provided with a material limiting plate 122 which is movably connected up and down and used for limiting the discharging of the first material conveying outlet 121 b. The size of the first material outlet 121b can be adjusted by sliding the material limiting plate 122 up and down, so as to adjust the speed of material discharge.

Referring to fig. 2, the first frame 15 is further provided with clamping plates 152 (four clamping plates are shown in two-to-two symmetry, not labeled one by one), and the clamping plates 152 are symmetrically disposed on the inner surfaces of the two side shells of the housing 151. The upper edge of the clamping plate 152 is bent and then connected with the inner surface of the side shell, the lower edge of the clamping plate 152 is provided with a first bent part 152a, and the first bent part 152a faces the direction of the side shell and has a gap with the side shell. Two sides of the main screen 131 are provided with upward second bent portions 131a, and one first bent portion 152a is respectively engaged with one corresponding second bent portion 131 a. The first bent part 152a may be formed in a right angle shape, and the second bent part 131a is formed in an acute angle with the main screen 131, so that the clamping is more firmly performed.

During installation, one end of main screen 131 is aligned with one end of clamping plate 152, and main screen 131 is pushed to be clamped with clamping plate 152. Main screen 131 sets up to detachable construction, can change into main screen 131 of different sieve mesh external diameters according to the button size of waiting to screen during the use.

The first housing 15 further includes a mounting bracket 153, four spring legs 154 (not shown), and four pulleys 155 (not shown). The fixing frame 153 is horizontally disposed below the body of the first frame 15 and has a rectangular shape. Four pulleys are located below four vertices of the fixing frame 153 to facilitate the moving position of the outer diameter sorting apparatus 100 for buttons. Four spring legs 154 are longitudinally disposed between the mount 153 and the housing 151. Four spring legs 154 are located above the four vertices of the holder 153. The spring legs 154 cooperate with the vibrator 14 to increase the vibration amplitude of the outer diameter sorting apparatus 100 for buttons, thereby improving the button sorting efficiency.

[ second embodiment of an outer diameter sorting apparatus for buttons ]

Referring to fig. 3 in conjunction with fig. 4, the main screen 131 includes a first main screen 131b and a second main screen 131c, and the first main screen 131b is located above the second main screen 131 c.

The second embodiment of the outer diameter sorting device for buttons mainly differs from the first embodiment in that the first material conveying device 12 further comprises a first material guide plate 123, and the outer diameter sorting device 13 further comprises an auxiliary screen 133, a second material guide plate 134, a third material guide plate 135, a first guide opening 136, a second guide opening 137, a first guide hopper 138 and a second guide hopper 139.

The first guide plate 123 is connected to an obliquely lower portion of the first transfer outlet 121b, and is provided with guide holes 123 a. The auxiliary screen 133, the second material guide plate 134 and the third material guide plate 135 are shorter than the main screen 131, and are all located above the first main screen 131b near one end of the first material conveying device 12, and are sequentially arranged from top to bottom as the auxiliary screen 133, the third material guide plate 135 and the second material guide plate 134, and the inclination directions of the auxiliary screen 133, the third material guide plate 135 and the second material guide plate 134 are all opposite to the inclination direction of the main screen 131.

The auxiliary screen 133 is positioned below the material guide holes 123a to screen the discharged material from the material guide holes 123a, and the outer diameter of the auxiliary screen 133 is equal to that of the first main screen 131 b. The first guide port 136 is connected to an end of the auxiliary screen 133 away from the material guide hole 123a, an input port of the first guide funnel 138 is positioned below the first guide port 136, and an output port of the first guide funnel 138 is positioned above the first main screen 131 b. The first diversion funnel 138 may be configured to removably attach to the housing 151.

The buttons having the larger outer diameter among the buttons flowing into the auxiliary screen 133 from the material guide holes 123a do not leak from the holes of the auxiliary screen 133, and flow toward the first guide port 136 in the inclined direction of the auxiliary screen 133, then flow toward the first guide funnel 138 from the first guide port 136, and then flow toward the first main screen 131 b. Since the outer diameter of the first main screen 131b is equal to the outer diameter of the auxiliary screen 133, the buttons cannot escape from the openings, but continue to flow toward the output end of the first main screen 131b along the inclined direction of the first main screen 131b, and finally flow out of the material separating port 132 corresponding to the first main screen 131 b.

The second guiding opening 137 is connected to one end of the third material guiding plate 135 far away from the first material guiding plate 123, the input opening of the second guiding hopper 139 is located below the second guiding opening 137, and the output opening of the second guiding hopper 139 is located above the second main screen 131 c. The second diverting hopper 139 may be configured to be removably attached to the housing 151.

The buttons having smaller outer diameters flow into the auxiliary screen 133 from the material guiding holes 123a, and then flow down through the holes of the auxiliary screen 133, onto the third material guiding plate 135, and then flow into the second guiding opening 137 along the inclined direction of the third material guiding plate 135, and then flow into the second guiding funnel 139, and then flow into the second main screen 131c from the outlet of the second guiding funnel 139. If the buttons cannot be dropped through the holes of the second main screen 131c, the buttons flow toward the material discharge ports 132 of the second main screen 131c along the oblique direction of the second main screen 131 c. If the buttons can be dropped through the holes of the second main screen 131c, the buttons fall into the bottom case and flow out. With this arrangement, the end of the second main screen 131c away from the material separating port 132 can be fully utilized, and the efficiency is higher.

One end of the second guide plate 134 is located below the edge of the first guide plate 123 to guide the discharged material at the edge of the first guide plate 123 to the first main screen 131b, and the first guide plate 123 may be provided in an L-shape with a baffle plate to maximize the flow of the discharged material to the second guide plate 134. The discharged material flows to the first main screen 131b below the second material guiding plate 134 along the inclined direction thereof, and is further screened. Through the arrangement of the second material guide plate 134, one end of the first main screen 131b away from the material separating port can be fully utilized, and the efficiency is higher.
