Detailed Description
Example (b): as shown in fig. 1 to 3, a dispenser for quantitatively dispensing glue comprises a support 2, a cylinder 1 and a linear guide rail 3, wherein the linear guide rail 3 is fixed on the support 2, a piston rod of the cylinder 1 is fixed with a slide block 4, the slide block 4 is inserted and sleeved on the linear guide rail 3, a support plate 5 is welded and fixed at the lower end of the linear guide rail 3, and the support plate 5 is an L-shaped plate;
the structure of the dispensing device 7 is as follows: the dispensing cylinder 71 is in a syringe shape, the dispensing cylinder 71 is provided with a dispensing nozzle 72, a cylinder cover 73 is screwed on the dispensing cylinder 71, a small servo motor 76 is fixed on the cylinder cover 73, a rotating shaft of the small servo motor 76 is fixed with a screw rod 77, the screw rod 77 is screwed with a piston block 74, a piston ring groove 741 is formed on the piston block 74, a sealing ring 75 is clamped in the piston ring groove 741, the sealing ring 75 is a split ring, the outer diameter surface of the sealing ring 75 is elastically pressed on the inner diameter surface of the dispensing cylinder 71, and at least two sealing rings 75 are arranged on the piston block 74;
the lower end of the dispensing cylinder 71 is pressed on the support plate 5, the dispensing nozzle 72 is inserted in a preset hole in the support plate 5, the left end of the hoop 6 is welded and fixed on the support plate 5, and the dispensing cylinder 71 is fastened on the hoop 6.
The distance between the lower end surface of the screw rod 77 and the bottom plate of the dispensing cylinder 71 is 0.5-2 mm.
And a piston rod of the cylinder 1 and the sliding block 4 are welded or fixed together by a screw.
The dispensing cylinder 71 is a transparent plastic part, the cylinder cover 73 is a plastic part, and the piston block 74 and the sealing ring 75 are alloy parts.
The linear guide rail 3 is fixed on the support 2 through a countersunk head screw 8.
