Detailed Description

Example (b): a pointing machine, as shown in FIGS. 1 and 2, includes a frame 1 and a roll stand 2 disposed above the frame 1. The roll seat 2 is U-shaped, a roll group 3 is arranged in the roll seat 2, and the roll group 3 comprises an upper roll 31 and a lower roll 32 which is arranged in parallel with the upper roll 31. The upper roll 31 and the lower roll 32 are fixed on the wall of the roll stand 2 by bearings. A driving mechanism 33 for driving the roll set 3 to rotate is arranged at one side of the roll seat 2, and the driving mechanism 33 comprises a pair of driving gears 331 which are coaxially arranged with the roll set 3 and are meshed with each other, and a motor 332 for driving one of the driving gears 331 to rotate. An output shaft of the motor 332 is fixedly connected with the driving gear 331, and a reducer 333 is provided on the output shaft of the motor 332. The worker drives the driving gear 331 to rotate by starting the motor 332, so that the roller group 3 rotates, the metal wire is placed in a gap between the upper roller 31 and the lower roller 32, and the metal wire is sharpened by the friction between the upper roller 31 and the lower roller 32.

As shown in fig. 1 and 2, the roll group 3 is likely to generate heat by the long-term rotation of the roll group 3, and the metal wire rod is likely to be bent, thereby affecting the quality of the metal wire rod. In order to reduce the possibility of heat generation of the roll stack 3, the roll stack 3 is cooled, and a cooling device 4 is provided on the roll stand 2. The cooling device 4 includes the wetting subassembly 41 that is used for wetting roll group 3 and soaks a plurality of shower nozzle 42 (this embodiment is 3) that the subassembly 41 sprayed water to wetting, soaks the subassembly 41 and includes the cotton 411 and the shell 412 of setting outside the cotton 411 that absorb water with roll group 3 butt, and the shell 412 is hung and is established on roll seat 2, and the shower nozzle 42 sets up in the cotton 411 top that absorbs water, and 3 shower nozzles 42 are crossed on establishing roll seat 2 through water pipe 421. Referring to fig. 3, the outer shell 412 is U-shaped with an opening facing the nozzle 42, a water flowing port 413 is formed on one side of the outer shell 412 facing away from the nozzle 42, and a bottom wall of the outer shell 412 is inclined towards the water flowing port 413, so that water on the absorbent cotton 411 flows into the water flowing port 413 conveniently. A water collecting tank 43 for collecting water is arranged below the water flowing port 413, a conduit 431 is communicated with the bottom of the water collecting tank 43, and a water collecting tank 432 is communicated with the conduit 431. Through on with shower nozzle 42 with the water injection to the cotton 411 that absorbs water in the water pipe 421 for the roll set 3 that is close to with the cotton 411 that absorbs water is stained with the water on the cotton 411 that absorbs water, thereby reduces the temperature to roll set 3, reduces the metal wire and takes place crooked possibility. The excessive water on the absorbent pad 411 drops into the water collection tank 43 through the water flow opening 413, and flows from the conduit 431 on the water collection tank 43 to the water collection tank 432, so that the water dropping on the absorbent pad 411 is collected.

As shown in fig. 2, in the process of contacting the absorbent cotton 411 with the roll group 3, the heat on the roll group 3 is transferred to the absorbent cotton 411, thereby reducing the cooling effect of the absorbent cotton 411 on the roll group 3. In order to enhance the cooling effect of the absorbent cotton 411 on the roll set 3, a fan 5 for blowing air to cool the absorbent cotton 411 is arranged on the roll seat 2, the fan 5 is fixed on the roll seat 2, an air outlet of the fan 5 faces the absorbent cotton 411, and cold air blown out by the fan 5 reduces the temperature of water on the absorbent cotton 411, so that the cooling effect on the roll set 3 is enhanced.

As shown in fig. 1 and 2, in the process of sharpening the metal wire by the roller group 3, the worn metal scraps of the metal wire fall below the roller group 3, in order to facilitate the workers to process the metal scraps, a collecting assembly 6 for collecting the metal scraps is arranged below the roller group 3, the collecting assembly 6 comprises a collecting tank 63 arranged below the roller group 3, a scraper 61 connected with the side wall of the collecting tank 63 in a sliding manner, and a cylinder 62 for driving the scraper 61 to move, a piston rod 621 passing through the cylinder 62 extends out, the pushing scraper 61 slides in the collecting tank 63, and the metal scraps falling onto the collecting tank 63 are pushed out of the roller seat 2. With reference to fig. 4, in order to enhance the stability of the scraper 61 during the movement process, a sliding groove 21 is provided on the side wall of the collecting groove 63, and a sliding block 611 which is matched with the sliding groove 21 for sliding is provided on the scraper 61. The blade 61 is disposed obliquely downward from the bottom of the lower roll 32, and the blade 61 does not affect the rotation of the roll stack 3. Roll set 3 is at the rotation in-process, and the piston rod 621 of cylinder 62 retracts for scraper blade 61 shelters from water catch bowl 43, thereby makes the metal sweeps that produces pass through stopping of scraper blade 61, directly drops on scraper blade 61, can not drop in the water catch bowl 43, and the staff of being convenient for clears up the metal sweeps that is located roll set 3 below.

The working process is as follows: the water absorption cotton 411 is wetted by the spray head 42, so that the roll group 3 abutted against the water absorption cotton 411 is wetted, the roll group 3 is cooled, and the possibility of bending of the metal wire in the pointing process is reduced; when the heat of the roll group 3 is transferred to the absorbent cotton 411, the cold air blown by the fan 5 can cool the absorbent cotton 411, so that the cooling effect on the roll group 3 is enhanced; the excess water on the absorbent cotton 411 flows into the water collecting tank 43 through the water flowing port 413 and flows into the water collecting tank 432 through the conduit 431, and the waste water is collected; in the process of pointing the metal wire by the roller group 3, the generated metal scraps are scraped out of the lower part of the roller group 3 through the scraper 61, so that the cleaning difficulty of workers is reduced.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
