[0022] As Figure 1As shown, the granular material rolling brush feeder comprises a feeding seat 1, a feeding frame 2 and a plurality of feeding rolling brushes 6, the feeding frame 2 is installed on the feeding seat 1, the feeding rolling brushes 6 are located in the feeding frame 2, and the feeding frame 2 is provided with a feeding port 50 through which the granular material enters (a glass or organic glass plate is installed on the top of the feeding frame 2, and the feeding port 50 is installed on the glass or organic glass plate), as shown in Figure 5 As shown, the feeding rolling brush 6 comprises a rolling shaft 60 and feeding bristles 61, the feeding bristles 61 are connected to the rolling shaft 60 in an axial direction in a spiral direction or in a plurality of rows of inclined directions ("spiral direction" means that the feeding bristles 61 are connected to the rolling shaft 60 in a continuous spiral direction; "a plurality of rows of inclined directions" means that the feeding bristles 61 form an inclined row, as shown in Figure 6 As shown, a plurality of such feeding bristles 61 are connected to the rolling shaft 60 in an axial arrangement direction), and the rolling shaft 60 is drivingly connected to a brushing power source 90 that drives the rolling shaft 60 to rotate around the axis, as shown in Figure 4 As shown, a plurality of feeding rolling brushes 6 are arranged in the front-rear direction (as shown in Figure 1 the direction of the arrow, that is, the feeding direction of the bubble cap, and other direction-related descriptions are based on the direction of the arrow), and each feeding rolling brush 6 is transversely arranged (that is, the axis of the feeding rolling brush 6 is horizontally arranged).

[0023] The working principle of the granular material rolling brush feeder is as follows: the granular material enters the feeding frame 2 through the feeding port 50, the brushing power source 90 drives the plurality of feeding rolling brushes 6 to rotate, the plurality of feeding rolling brushes 6 rotate around the axis to achieve rolling brushing, the feeding rolling brush 6 closest to the feeding port 50 first brushes the granular material forward, and through the action of the plurality of feeding rolling brushes 6, the granular material is constantly moved forward to reach the feeding rolling brush 6 at the frontmost position, so that the granular material is moved in the front-rear direction; as shown in Figure 6 As shown, the feeding rolling brush 6 rotates around the axis while the feeding bristles 61 thereof have a left-right swinging direction, so that the granular material can be moved in the left-right direction, thereby achieving omnidirectional movement of the granular material, so that the granular material can more easily cover the feeding area in all aspects. As shown in Figure 2 As shown, the plurality of feeding rolling brushes 6 are arranged together in the front-rear direction to form a square, and the feeding frame 2 is also square, so that the feeding area of the feeding frame 2 can be fully covered without any dead angle, and the bubble cap will not be out of material. At the same time, since the feeding rolling brush 6 is rolling brushing rather than pressing brushing, it will not cause physical damage to the granular material, and the material will fall into the bubble cap in the most perfect granular shape.

[0024] In order to meet the feeding of bubble caps of different widths, as shown in Figure 2As shown, the feeding frame 2 has two adjustable-spaced dividing plates 26, and the feeding roller brush 6 is located between the two dividing plates 26. When feeding blister packs of different widths, simply adjust the spacing between the two dividing plates 26 to match the width of the blister pack. Of course, feeding blister packs of different widths requires replacing the feeding roller brush 6 with one of different lengths to ensure that the feeding roller brush 6 covers the space between the two dividing plates 26. Figure 2 As shown, a scale plate 27 is installed on the feeding frame 2. The scale plate 27 has elongated holes in the left and right directions. The spacing plate 26 is connected to a bolt or plunger. The bolt or plunger passes through the elongated holes of the scale plate 27. In this way, moving the bolt or plunger can adjust the left and right position of the spacing plate 26.

[0025] like Figure 4 As shown, the brushing power source 90 is installed on the feeding base 1, and the brushing power source 90 is connected to the connecting shaft 9 for transmission. Figure 5 As shown, a pin 93 is connected to the connecting shaft 9, and the roller 60 has a shaft hole 62 and a slot 63. The connecting shaft 9 can be inserted into the shaft hole 62 of the roller 60, and the pin 93 can be inserted into the slot 63. This structure allows the connecting shaft 9 to drive the roller 60 to rotate, and also facilitates the connection between the two. Figure 4 As shown, among the multiple feeding roller brushes 6, some adjacent feeding roller brushes 6 can be driven by a single brushing power source 90. This can be achieved using a synchronous pulley 92 and a synchronous belt structure, synchronously driving the two connecting shafts 9 to rotate. The brushing power source 90 can then drive one of the connecting shafts 9 to rotate via a helical gear 91, thus saving costs. Alternatively, each connecting shaft 9 can be connected to a single brushing power source 90.

[0026] like Figure 2 As shown, a material-blocking roller brush 7 is provided inside the feeding frame 2. The material-blocking roller brush 7 is located at the forefront of all the feeding roller brushes 6. The material-blocking roller brush 7 includes material-blocking bristles and a roller. The material-blocking roller brush 7 is arranged horizontally and is connected to the power source 70 that drives the material-blocking roller brush 7. The rotation direction of the material-blocking roller brush 7 is opposite to the rotation direction of the feeding roller brush 6. Its function is to make the granular material move back and prevent the granular material from accumulating at the end.

[0027] In order to extract the dust (particulate materials will generate dust) from the feed box 2, such as Figure 2As shown, a blocking plate 8 is arranged above the rear side of the blocking roller brush 7, and the blocking bristles of the blocking roller brush 7 act on the blocking plate 8. A dust suction connector 25 is arranged on the feeding frame 2 near the blocking roller brush 7, and the dust suction connector 25 is used to be connected with the air suction machine. When the blocking roller brush 7 rotates, the blocking bristles of the blocking roller brush 7 will act on the blocking plate 8 and bend downward. When the bent blocking bristles pass through the blocking plate 8, the blocking bristles will pop up upward due to the rapid reset, so that the dust on the blocking bristles will be lifted upward, and the air suction machine can suck away the dust. In addition, the blocking plate 8 can also block the material, so that the material cannot enter the space above the blocking roller brush 7, but only stays behind the blocking plate 8 (i.e. the position of the brushing area).

[0028] In order to facilitate the disassembly of the feeding frame 2, as shown, Figure 3 The feeding seat 1 comprises two supporting plates 10 arranged in front and back, and the inner side of the supporting plate 10 is provided with a guide groove 11. The feeding frame 2 has two push plates, and the push plate is provided with a guide strip 29 which can move in the guide groove 11. When installing, only the guide strip 29 of the feeding frame 2 is pushed into the guide groove 11 of the feeding seat 1, and then it is fixed by the spring pin, which is convenient and fast to disassemble and assemble.

[0029] As shown, Figure 1 The feeding device further comprises a hopper 3 and a vibrator 4. The hopper 3 is installed on the vibrator 4, and the discharge port of the vibrator 4 is connected with the feeding port 50 of the feeding frame 2 through a pipeline 5. The material is added to the hopper 3, and the valve on the hopper 3 controls the material to enter the vibrator 4. The vibrator 4 vibrates to send the material into the feeding frame 2 through the pipeline 5.

[0030] A first photoelectric sensor 30 is installed at the bottom of the hopper 3, and the first photoelectric sensor 30 is electrically connected with the control center (the control center is a PLC control system). The control center is connected with an alarm. When the first photoelectric sensor 30 detects that the hopper 3 is out of material, it sends a signal to the control center, and the control center controls the alarm to issue an alarm.

[0031] As shown, Figure 2 A second photoelectric sensor 28 is arranged in the feeding frame 2, and the second photoelectric sensor 28 is electrically connected with the control center. The control center controls the vibrator 4 to work. When the second photoelectric sensor 28 detects that the feeding frame 2 is short of material, it sends a signal to the control center, and the control center controls the vibrator 4 to work. The vibrator 4 vibrates to send the material into the feeding frame 2 through the pipeline 5.

[0032] In order to detect the material in the charging frame 2 at different heights, the second photoelectric sensor 28 is mounted on a connecting block which is adjustably mounted on a connecting seat connected to the charging frame 2. By adjusting the up-down position of the connecting block, the position of the second photoelectric sensor 28 can be adjusted, so that the second photoelectric sensor 28 can detect the material in the charging frame 2 at different heights.
