[0031] Combined with Figures 1 to 5 As shown, a feeding device for the bristles of a sealing brush provided by the present utility model includes a primary feeding device 1, a single-layer fixing device 2, a secondary feeding device 3 and a multi-layer fixing device 4.
[0032] Combined with Figures 1 to 5 As shown, the primary feeding device 1 is provided with a discharge port for discharging bristles, and the size of the discharge port only allows the bristles to pass through layer by layer; the single-layer fixing device 2 receives the bristles output by the primary feeding device 1, and the single-layer fixing device 2 fixes the positional relationship between the bristles to form a single-layer brush; the secondary feeding device 3 outputs the single-layer brush in the single-layer fixing device 2; the multi-layer fixing device 4 receives and stacks the single-layer brushes output by the secondary feeding device 3, and the multi-layer fixing device 4 fixes the positional relationship between the single-layer brushes to form a sealing brush.
[0033] In this embodiment, the fixation of the bristles is divided into two steps. The bristles are fed into the single-layer fixing device 2 by the primary feeding device 1 to form a single-layer brush, so that the bristles are first arranged in layers. Then, the single-layer brush is fed into the multi-layer fixing device 4 by the secondary feeding device 3 to form a sealed brush, so that the layered bristles are stacked into a sealed brush, realizing the standardized arrangement of the bristles inside the sealed brush, increasing the utilization rate of the internal space of the sealed brush, reducing the packaging pressure while ensuring the bristle density, and improving the service life of the sealed brush.
[0034] In this embodiment, the bristles of the single-layer brush formed by the single-layer fixing device 2 can be one or two layers. The main characteristics of the single-layer brush are that the number of bristle layers is small, and the arrangement of the internal bristles is regular and tight, mainly because the fewer the number of bristle layers, the simpler the arrangement of the bristles and the less likely to appear gaps.
[0035] In some embodiments, in combination with Figure 2 As shown, the primary feeding device 1 includes a discharge box 11 and a blanking plate 12. The discharge port is opened on the side of the discharge box 11. The bottom edge of the discharge port is flush with the bottom plate of the discharge box 11. The blanking plate 12 is flush with the bottom plate. The blanking plate 12 is integrally formed and connected to the discharge box 11 in the direction where the discharge port is located. The discharge box 11 stores bristles inside, and the bristles are output to the blanking plate 12 through the discharge port. The bristles on the blanking plate 12 are arranged in layers and move towards the single-layer fixing device 2.
[0036] In some embodiments, in combination with Figure 2 As shown, the primary feeding device 1 further includes a rotating shaft 13. The rotating shaft 13 is rotatably assembled in the discharge port. The rotating shaft 13 fits against the top edge of the discharge port. There is a gap between the rotating shaft 13 and the bottom edge of the discharge port. The main function of the rotating shaft 13 is to prevent blockage by rotation. When the rotating shaft 13 rotates against the movement direction of the bristles, the anti-blocking effect is better. At the same time, it can avoid the problem that the rotating rotating shaft 13 accelerates the bristles and causes the bristles to stack.
[0037] In some embodiments, in combination with Figure 2 As shown, the primary feeding device 1 further includes an eccentric rotating shaft 14. The eccentric rotating shaft 14 is located directly above the end of the blanking plate 12 far from the discharge box 11. The maximum outer diameter of the rotation of the eccentric rotating shaft 14 abuts against the upper surface of the blanking plate 12. The function of the eccentric rotating shaft 14 is similar to that of a gate to control the transfer of the bristles. During the rotation of the eccentric rotating shaft 14, the gap between the outer surface and the blanking plate 12 will change, which can avoid the problem of bristle stacking caused by driving the bristles when switching between the conducting states.
[0038] In some embodiments, in combination with Figure 3As shown, the single-layer fixing device 2 includes a fixing plate 21, a first push rod 22, a pressing plate 23, a second push rod 24, and a hot pressing plate 25. The first push rod 22 is fixedly connected to the fixing plate 21, the driving end of the first push rod 22 is fixedly connected to the pressing plate 23, the second push rod 24 is fixedly connected to the pressing plate 23, and the driving end of the second push rod 24 is connected to the hot pressing plate 25. The first push rod 22 is a driving device for the up and down movement of the pressing plate 23. The pressing plate 23 fixes the position of the bristles by pressing down to prevent them from shifting during the hot pressing and shaping process. The second push rod 24 is a driving device for the downward movement of the hot pressing plate 25, and the hot pressing plate 25 can press down to fix the position between the bristles by hot pressing.
[0039] In some embodiments, as shown in Figure 1 、 Figure 3 the secondary feeding device 3 is a conveyor belt. The upper end of the secondary feeding device 3 is bridged to the primary feeding device 1. The secondary feeding device 3 is located directly below the single-layer fixing device 2. The secondary feeding device 3 can transport the bristles to directly below the single-layer fixing device 2, and the secondary feeding device 3 can also output single-layer brushes.
[0040] In some embodiments, as shown in Figure 4 there are limiting baffles 31 on both sides of the secondary feeding device 3. The limiting baffles 31 can fix the position of the bristles to ensure the fixing effect of the single-layer fixing device 2.
[0041] In some embodiments, as shown in Figure 4 the multi-layer fixing device 4 includes a collector 41 and a hot press 42. The collector 41 is located below the outlet of the secondary feeding device 3. The single-layer brushes are stacked and placed into the collector 41, and the fixed ends of the bristles of the single-layer brushes protrude from the inside of the collector 41. The hot press 42 hot presses the fixed ends of the bristles of multiple single-layer brushes. The collector 41 stacks and stores the single-layer brushes, and the hot press 42 hot presses and fixes the multiple stacked single-layer brushes to form a sealed brush.
[0042] In some embodiments, as shown in Figure 5 the collector 41 includes a collecting bucket 411 and a track 412. The collecting bucket 411 is slidably assembled on the track 412. The collecting bucket 411 passes directly below the outlet of the secondary feeding device 3 during the sliding process. The collecting bucket 411 adjusts the position directly below the outlet of the secondary feeding device 3 by sliding on the track 412 to achieve stacking and storing of single-layer brushes.
[0043] In some embodiments, as shown in Figure 5As shown, the hot press 42 includes two hot pressing heads 421 distributed vertically. The two hot pressing heads 421 are respectively driven by hot pressing push rods 422. The two hot pressing heads 421 hot press the single-layer brush from the upper and lower directions. The hot press 42 and the collector 41 cooperate. The hot pressing push rod 422 drives the hot pressing head 421 to perform the hot pressing operation, which can avoid running interference with the collecting bucket 411 during its movement.
[0044] Working process: The bristles pass through the discharge port of the discharge box 11 layer by layer. The bristles are arranged in layers on the blanking plate 12. The bristles arranged in layers finally enter directly below the single-layer fixing device 2. The first push rod 22 extends to drive the fixing plate 21 to press the bristles tightly. The second push rod 24 extends to drive the hot pressing plate 25 to hot press and fix one end of the brush, and the bristles form a single-layer brush.
[0045] After the single-layer brush is formed, the single-layer fixing device 2 is lifted. The secondary feeding device 3 operates to send the single-layer brush into the multi-layer fixing device 4. The single-layer brushes are stacked and placed into the collector 41. The hot press 42 hot presses and fixes the fixed end of the single-layer brush, and the single-layer brush forms a sealed brush.
[0046] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
