Detailed Description
As shown in fig. 1 to 11, the present invention mainly includes a belt conveyor 1, a pitch adjusting unit, a positioning unit and an injection unit, and the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the belt conveyor 1 runs through various processes and is used for conveying the conical flasks 7, when in use, the conical flasks are placed on the belt conveyor, and under the action of the belt conveyor, the conical flasks pass through the various processes and are subjected to different operation treatments in different processes, and the belt conveyor is used for adding a fixed volume of liquid into the conical flasks.
As shown in fig. 1, a pitch adjusting unit and a positioning unit are sequentially arranged from front to back along the conveying direction of the belt conveyor, as shown in fig. 3 to 7, the pitch adjusting unit comprises a support 2 crossing the belt conveyor, an adjusting motor 22 fixed at the top of the support, two first driving gears 23 arranged left and right on the support in a rotating manner, two swing gears 24 arranged on the support in a rotating manner, and a stop lever 21 arranged below the swing gears and coaxial with the swing gears, wherein the two first driving gears are engaged and matched and are positioned between the two swing gears, and the swing gears are externally engaged with the corresponding first driving gears. One of the two first driving gears rotates under the driving of the adjusting motor. The adjustment motor during operation can drive the rotation of first driving gear, and then drives swing gear's rotation, and then realizes the swing of two pin, and swing opposite direction when two pin move, and a clockwise oscillation promptly, another anticlockwise oscillation. The stop lever comprises a linear part and an arc-shaped part, wherein the arc-shaped part of the stop lever is fixedly connected with the oscillating gear. As shown in fig. 5, when the straight portions of the two bars approach each other and contact the erlenmeyer flask, the erlenmeyer flask can be blocked and prevented from moving along with the belt conveyor. When the conical bottle needs to be released, the first driving gear is driven to rotate through the adjusting motor, so that the two blocking rods are far away from each other, the blocking rods are separated from the conical bottle, the blocking effect of the blocking rods on the conical bottle disappears, and the conical bottle continues to move along with the belt conveyor; two fenders keep away from each other until the fender pole disappears the back to blockking of erlenmeyer flask, the accommodate motor is reverse action immediately for two fenders are close to each other, in order to realize blockking of follow-up erlenmeyer flask. The stop lever acts once every fixed time interval to release one conical flask, and because the stop lever has the same stop time for the conical flasks, the conical flasks are arranged at equal intervals after passing through the distance adjusting unit under the action of the distance adjusting unit. The function of the distance adjusting unit is to rearrange the conical bottles on the belt conveyor, so that the conical bottles are arranged in sequence at the set distance on the belt conveyor. The support 2 is of a gantry structure, and the belt conveyor is arranged on the inner side of the support. The first driving gear, the swing gear and the adjusting motor form a swing driving mechanism.
As shown in fig. 8 to 11, the positioning unit includes mounting plates 3 disposed on the left and right sides of the belt conveyor, two positioning blocks 4 slidably disposed between the two mounting plates, and a lift driving mechanism for driving the two positioning blocks to move up and down, as shown in fig. 9, the positioning blocks are of a rectangular structure, a positioning groove 41 is disposed in the middle of the front end face of the positioning block 4, a guide surface 42 is disposed between the positioning groove and the side wall of the positioning block, the guide surface is disposed to facilitate the accurate sliding of the erlenmeyer flask into the positioning groove, and at this time, the outer wall of the lower portion of the erlenmeyer flask contacts with the positioning groove. The left side wall and the right side wall of the positioning block are provided with slide blocks 43, and the mounting plate is provided with a slide groove in sliding connection with the slide blocks. Under the cooperation of the sliding block and the sliding groove, the positioning block moves up and down relative to the mounting plate. The two positioning blocks are arranged in a front-back mode, the moving directions of the two positioning blocks are opposite when the two positioning blocks move, namely, when the positioning block on the front side moves upwards, the positioning block on the rear side moves downwards. To achieve the purpose, a lifting driving mechanism is arranged between the positioning block and the mounting plate, as shown in fig. 8 and 11, the lifting driving mechanism comprises a lifting motor 54 fixed on one of the mounting plates, a worm 53 fixed at the output end of the lifting motor, a worm wheel 52 engaged with the worm and rotatably connected with the mounting plate, a second driving gear 5 coaxially arranged with the worm wheel, and driven gears 51 arranged at the front side and the rear side of the second driving gear, and the two driven gears are rotatably connected with the mounting plate. And racks 44 are fixed at the top of the positioning block, the two racks correspond to the two driven gears one by one, and the corresponding driven gears are meshed with the racks. The elevating motor during operation can order about two driven gear's synchronous rotation, and two driven gear rotate the reverse the same, again because two driven gear set up between two vertical racks that set up, therefore during the elevating motor action, two racks one moves on top of one, and then orders about two locating pieces one moves on top of one. When the rear side positioning block is arranged at the lowest point, the front side positioning block is arranged at the highest point, the positioning groove on the positioning block is contacted with the conical flask, at the moment, the conical flask is still, and liquid with a fixed volume can be added into the conical flask. When the rear side positioning block is arranged at the highest point, the front side positioning block is arranged at the lowest point; and then the lifting motor moves reversely, so that the rear side positioning block moves downwards and the front side positioning block moves upwards. And after the rear side positioning block moves downwards to the lowest point again, the rear side positioning block waits for contact with a subsequent conical flask, so that the conical flask is positioned.
As shown in figure 1, the injection unit comprises an injection pump 6 fixed on the mounting plate and a conduit 61 arranged at a liquid outlet of the injection pump, the lower end of the conduit is in a vertical state, and after a positioning groove on a rear side positioning block is contacted with the conical flask, the lower end of the conduit is just positioned right above the mouth of the conical flask 7.
The utility model discloses can realize the transport to the erlenmeyer flask to carry the erlenmeyer flask to each process. Through the sequencing of the conical bottles, enough distance is ensured between the conical bottles so that the positioning blocks can be contacted with the conical bottles, and after the injection unit adds liquid into the conical bottles, the subsequent conical bottles still do not reach the position below the front side positioning blocks. The device can high-efficiently realize adding the liquid of fixed volume in to the erlenmeyer flask, and then improves inspection efficiency.
