DETAILED DESCRIPTION
[0018] The utility model will be further described below with reference to the drawings.
[0019] The buffer spray head mechanism of the utility model, as shown in Figure 1 and Figure 2 , comprises a spray head 1, and further comprises a transverse sliding seat 3, a buffer air cylinder 4 and a support 5, the transverse sliding seat 3 is slidingly connected to the support 5, and the "transverse" in the transverse sliding seat 3 is relative to the conveying direction of the plate 99, specifically, the plate 99 is conveyed along the longitudinal direction, so that the "transverse" is horizontal and perpendicular to the longitudinal direction, the buffer air cylinder 4 drives the transverse sliding seat 3 to move transversely, in other words, under the visual direction of Figure 2 , the buffer air cylinder 4 drives the transverse sliding seat 3 to move forward and backward, and the spray head 1 is arranged on the transverse sliding seat 3, that is to say, the buffer air cylinder 4 can drive the spray head 1 to move forward and backward, as shown in Figure 3 and Figure 4 , a guide outer fillet 1001 for guiding the right-angle edge 991 of the plate 99 is formed at the front end of the spray head 1, and the guide outer fillet 1001 is vertically arranged, specifically, the front part of the spray head 1 is substantially a cuboid, so that four edges are formed at the front end of the spray head 1, and the guide outer fillet 1001 is specifically formed at the vertical edge at the front end of the spray head 1.
[0020] The working principle of the buffer spray head mechanism of the utility model will be briefly described below: during normal operation, the buffer air cylinder 4 is kept connected to compressed air, so that the buffer air cylinder 4 keeps pushing the spray head 1 forward, and the spray head 1 is kept at the front limit position; as shown in Figure 6As shown, the chain plate conveying device drives the plate 99 to move to the left, and the plate is rectangular, so the plate 99 includes four right angle edges 991, and specifically, the right angle edge 991 of the left rear end of the plate 99 first approaches the right front end of the spray head 1. Under normal circumstances, the rear side of the plate 99 will slide against the front of the spray head 1, that is, the right angle edge 991 of the left rear end of the plate 99 does not collide with the spray head 1 (even without contact); When the plate 99 is occasionally slightly skewed or the flatness of the rear side of the plate 99 is poor, the right angle edge 991 of the left rear end of the plate 99 may collide with the spray head 1, specifically, the right angle edge 991 of the left rear end of the plate 99 collides with the guide outer round corner 1001. In the process of the guide outer round corner 1001 sliding to the left front relative to the guide right angle edge 991, in fact, the right angle edge 991 pushes away the spray head 1, so that the spray head 1 moves backward (that is, the pushing force of the plate 99 on the spray head 1 overcomes the forward pushing force of the buffer air cylinder 4 on the spray head 1), so as to avoid the rigid collision between the spray head 1 and the plate 99. In other words, the buffer spray head mechanism of the utility model makes the spray head be floatingly arranged; and since the buffer air cylinder 4 keeps pushing the spray head 1 forward, the compressed air for pushing the horizontal sliding seat 3 of the buffer air cylinder 4 forward plays a buffering role, so as to avoid the plate 1 from being scratched, and also avoid the spray head 1 and the parts connected with the spray head 1 from being damaged, that is, the buffer air cylinder can buffer the collision between the plate and the spray head, so as to be beneficial to improving the plate product quality and also beneficial to stable production; then the spray head 1 keeps abutting against the rear side of the plate 99 through the pushing force of the buffer air cylinder 4. In other words, since the buffer air cylinder 4 keeps pushing the spray head 1 forward, in the process of the spray head 1 being pushed backward by the plate 99, the spray head 1 will not obviously move backward away from the plate 99. In the case that the collision between the right angle edge 991 of the plate 99 and the guide outer round corner 1001 is slight, the spray head 1 can keep abutting against the plate 99. If the rear side of the plate 99 is slightly wavy due to machining defects, in the process of the plate 99 sliding through the spray head 1, the part of the rear side of the plate 99 that protrudes backward can push away the spray head 1, so as to avoid the rigid scraping between the spray head 1 and the rear side of the plate 99. When the relatively recessed part of the rear side of the plate 99 moves to the position of the spray head 1, the spray head 1 is pushed forward to abut against the above-mentioned relatively recessed part through the buffer air cylinder 4, or the spray head 1 is pushed to the forward limit position by the buffer air cylinder 4. When it is necessary to maintain the spray head 1, the buffer air cylinder 4 can be used to drive the spray head 1 to move backward to the rear limit position.
[0021] Further, as shown in Figure 2 The spray head 1 is provided with an oil baffle 11, and the oil baffle 11 includes a baffle body 111. The left and right ends of the baffle body 111 are respectively bent rearward to form two side plates 12, so that the oil baffle 11 has a groove shell structure, as shown in Figure 3 and Figure 5 The baffle body 111 abuts against the front side of the spray head 1, and the front end of the spray head 1 is arranged between the two side plates 12, as shown in Figure 3As shown, the baffle body 111 is formed with an arc groove 1111 which is adapted to the rounded edge 992 of the plate material 99, and the end of the arc groove 1111 is formed with a slot end rounded corner 113 which is used to guide the end of the rounded edge 992 of the plate material 99, and as shown, Figure 6 As shown, when the plate material 99 moves to the right front end of the nozzle 1, if the left end of the rounded edge 992 of the plate material 99 has burrs, the burrs can touch the slot end rounded corner 113, and through the guiding effect of the slot end rounded corner 113, the burrs gradually slide into the arc groove 1111, thereby avoiding the burrs from being rigidly collided to further damage the rounded edge 992. As shown, Figure 3 As shown, the oil baffle 11 is symmetrically distributed up and down, and as shown, Figure 6 As shown, then the upper and lower ends of the rounded edge 992 of the rear side of the plate material 991 respectively approaches the corresponding arc groove 1111, and in actual application, under normal working conditions, there is a gap (about 0.2mm to 0.5mm) between the arc groove 1111 and the rounded edge 992. In order to adapt the shape of the arc groove 1111 to the corresponding rounded edge 992, specifically, as shown, Figure 3 As shown, taking the baffle body 111 located at the lower position as an example, the arc groove 1111 can be formed by cutting the upper front edge corner of the baffle body 111 by a ball end mill. The oil baffle 11 is used to block the excess oil from being sprayed out of the oil injection gap 101, and by adjusting the distance between the upper and lower oil baffles 11, the actual oil injection range (in the up and down direction) of the nozzle 1 is adapted to the thickness of the plate material 99, and in order to enable the rounded edge 992 to also be sprayed with oil, the arc groove 1111 is formed with a notch which is aligned with the oil injection gap 101.
[0022] Further, as shown, Figure 1 and Figure 2 The buffer nozzle mechanism of the utility model further includes an oil return pipe 2, the front end of the oil return pipe 2 is installed and connected with the rear end of the nozzle 1, specifically, the front end of the oil return pipe 2 is provided with a flange structure, the above-mentioned flange structure is installed and connected with the plate piece of the rear end of the nozzle 1 through corresponding screws, one side of the oil return pipe 2 is installed and connected with the horizontal sliding seat 3, as shown, Figure 4 The front face of the nozzle 1 is formed with an oil injection gap 101 and an oil return port 102, the upper end of the nozzle 1 is formed with an oil inlet hole 1011, the oil inlet hole 1011 is communicated with the oil injection gap 101, the oil return port 102 is communicated with the front end of the oil return pipe 2, the rear end of the oil return pipe 2 is used to connect with a vacuum pump, the oil injection gap 101 is used to spray oil to the rear side of the plate material 99, and the oil return port 102 sucks away the excess oil; as shown, Figure 1 Specifically, the right side of the oil return pipe 2 is welded with a mounting plate, the mounting plate is relatively fixed to the left side of the horizontal sliding seat 3 through corresponding screws, through the above-mentioned setting, the nozzle 1 can be stretched forward from the horizontal sliding seat 3, and the oil sprayed by the nozzle 1 can be avoided from easily splashing to the sliding connection structure of the horizontal sliding seat 3 and the support 5.
[0023] Further, as shown,Figure 1 and Figure 2 As shown, two upper and lower slide rods 31 are fixedly connected to the transverse slide block 3. Specifically, the slide rods 31 pass through the transverse slide block 3 and are fixed to the transverse slide block 3 by screws connected to the set screws of the transverse slide block 3. The slide rods 31 are cylindrical, and a tail plate 32 is installed at the rear end of the slide rods 31 by corresponding screws. The cylinder body of the buffer cylinder 4 is installed on the rear side of the tail plate 32 by corresponding screws. The piston rod of the buffer cylinder 4 is connected to the support 5, and the slide rods 31 are slidably connected to the support 5. Thus, the slide rods 31 extend in the front-rear direction. Specifically, the support 5 is equipped with a linear bearing, and the slide rods 31 are adapted to and connected to the corresponding linear bearing. Specifically, the front end of the piston rod of the buffer cylinder 4 is screwed to the rear end of the support 5, and a nut is also screwed to the front end of the piston rod of the buffer cylinder 4. The nut presses against the rear end face of the support 5. Figure 1 As shown, the piston rod of the buffer cylinder 4 is located in the middle of the upper and lower slide rods 31. Therefore, when the piston rod of the buffer cylinder 4 retracts relative to the cylinder body of the buffer cylinder 4, the cylinder body of the buffer cylinder 4 drives the transverse slide block 3 to move forward. Because the piston rod of the buffer cylinder 4 is located in the middle of the upper and lower slide rods 31, it helps to balance the force on the transverse slide block 3 and facilitates its flexible forward and backward sliding. Figure 2 As shown, a travel limiting groove 301 is formed on the right side of the transverse slide block 3, and a stop block 51 is formed at the front of the support 5. The stop block 51 is located in the travel limiting groove 301. When the inner wall of the rear end of the travel limiting groove 301 contacts the stop block 51, the nozzle 1 reaches the front limit position; the slide rod 31 passes through the stop block 51.
[0024] Furthermore, such as Figure 3 As shown, a screw hole 1121 is formed on the side plate 12, such as Figure 4 and Figure 5 As shown, grooves 103 are formed on the left and right sides of the front end of the nozzle 1, and grooves 103 have bottom surfaces 1031. Screw holes 1121 are used to install pull screws 6 (it should be noted that only...). Figure 5 The pull screw 6 is schematically shown. The end of the pull screw 6 contacts the bottom surface 1031 of the corresponding groove. The depth of the groove 103 (i.e., Figure 5 The dimension "H" in the design is set to gradually increase from front to back. In other words, the bottom surface of the groove 1031 forms an acute angle with the front of the nozzle 1. Figure 5The size "H" in the drawing is gradually increased from front to back, so when the pull screw 6 is tightened, the pull screw 6 forms a pushing force along the left-right direction on the groove bottom surface 1031, and since the groove bottom surface 1031 is inclined to the back, the groove bottom surface 1031 generates a backward reaction force (component) on the pull screw 6, so that the pull screw 6 and the oil baffle 11 move backward together, so that the baffle body 111 is pressed against the front face of the nozzle 1, so that the relative position of the arc groove 1111 and the front face of the nozzle 1 is accurate (in the front-back direction), avoiding the risk of increasing the end of the arc groove 1111 colliding with the circular corner edge 992. The pull screw 6 can be a taper end set screw.
