TECHNICAL FIELD
[0001] The present application relates to the technical field of brush strip and brush wire separation, and particularly relates to a brush strip and brush wire separation pretreatment equipment. BACKGROUND
[0002] The brush roller for environmentally-friendly rust removal of steel plates gradually wears and shortens the brush wire until it is no longer applicable during the grinding and brushing. In order to achieve better rust removal effect on the steel plate, the brush wire of the present application is made of resin as the base material and mixed with diamond abrasive particles, which can achieve better effect during the grinding and brushing for rust removal. Some rust removal brush rollers of the present application are realized by installing brush strips on the outer side of the roller shaft in a ring shape. In order to save raw materials and avoid waste, the brush wire on the brush strip is collected and reused by melting.
[0003] Please refer to Figure 9 The existing brush strip is composed of a strip-shaped iron sheet, brush wire and iron wire. During the production of the brush strip, the brush wire is placed side by side on the upper surface of the iron sheet, and the iron wire is located at the center of the upper surface of the iron sheet. The iron wire is located above the brush wire and is placed along the length direction of the iron sheet. The outer side of the iron sheet is extruded by an extrusion wheel, so that the brush wire and the iron wire are extruded into the folded iron sheet on both sides. The iron sheet after being extruded by the extrusion wheel has a wider width at the rear folding part and a narrower width at the front clamping part, thereby achieving the fastening of the brush wire. This also brings inconvenience to the manual separation and recovery of the brush wire. First, the brush wire needs to be clamped by pliers and pulled outwards with force to separate the brush wire and the iron sheet. This has the problems of low separation efficiency of the brush wire and high labor cost. Second, since the brush wire needs to be pulled out with force, the worker is easily cut by the iron sheet due to the difficulty in controlling the force. If the front clamping part of the folded iron sheet can be opened before the brush wire and the iron sheet are separated, the iron sheet will no longer tighten the brush wire on both sides, and the brush wire can be easily pulled out by exerting a little force, thereby improving the low separation efficiency of the brush wire and reducing the high labor cost, and avoiding being cut by the iron sheet due to the difficulty in controlling the force. Therefore, the present application provides a brush strip and brush wire separation pretreatment equipment. SUMMARY

6. The brush bar and filament splitting pretreatment device as described in claim 1, characterized in that, The elastic element is a plurality of springs (33). The brush strip groove (11) is provided with a plurality of through holes on both the upper and lower sides. Bolts (34) are slidably installed in the through holes. The ends of the bolts (34) are fixedly installed on the upper surface of the upper limit plate (31) and the lower surface of the lower limit plate (32). Nuts are connected to the outer side of the bolts (34) by circumferential threads. The springs (33) are sleeved on the periphery of the bolts (34). The springs (33) are located between the upper side of the brush strip groove (11) and the upper limit plate (31) or between the lower side of the brush strip groove (11) and the lower limit plate (32).
7. The brush bar and filament splitting pretreatment device as described in claim 6, characterized in that, The first driving device includes several roller pairs, a linkage component, and a second servo motor (92). Several roller pairs are evenly distributed on the inner side of the brush strip groove (11). Each roller pair consists of two rollers (91) installed side by side. Several roller grooves (911) are opened on the inner side of the brush strip groove (11). Two rollers (91) are rotatably installed between the upper and lower sides of the roller groove (911). The two rollers (91) partially extend out of the roller groove (911) and are located in the brush strip groove (11). The second servo motor (92) drives several rollers (91) to rotate synchronously through the linkage component, so as to drive the brush strip (2) to slide horizontally along the length direction of the brush strip groove (11).
8. The brush bar and filament splitting pretreatment device as described in claim 7, characterized in that, The roller shaft of the roller (91) extends out of the upper surface of the support platform (1) and is coaxially fixedly connected to the driven wheel (93). Several driven wheels (93) are connected by a belt (931). The roller shaft of one roller (91) extends out of the upper surface of the driven wheel (93) and is coaxially fixedly connected to the first bevel gear (94). The output end of the servo motor (92) is coaxially fixedly connected to the second bevel gear (921). The second bevel gear (921) and the first bevel gear (94) are meshed. The servo motor (92) is fixedly installed on the upper surface of the support platform (1).
9. The brush bar and filament splitting pretreatment device as described in claim 8, characterized in that, The two driven wheels (93) corresponding to and close to the roller pair are driven wheel pairs. Two tensioning wheel pairs are provided between two adjacent driven wheel pairs. The tensioning wheel pairs are set close to the driven wheel pairs, so that the wrap angle between the belt (931) and the driven wheel (93) is less than 120°. The tensioning wheel pair includes two tensioning wheels (95) rotatably mounted on the upper surface of the support platform (1). The belt (931) passes around the outside of the driven wheel (93) and then passes around the inside of the tensioning wheel (95).
10. The brush bar and filament splitting pretreatment device as described in claim 1, characterized in that, The brush bar groove (11) has wedge-shaped surfaces (111) symmetrically arranged on the upper and lower sides, and the two wedge-shaped surfaces (111) and the vertical side of the brush bar groove (11) form a trumpet groove.
