Abstract

A bolt feeding mechanism is characterized by comprising a hopper, a rotation plate, a scraping board, a bolt sliding cover and a material storehouse, in which the rotation plate is of non magnetic material, the rotation plate is embedded with a bolt picking permanent magnet, the rotation plate can be rotatably arranged on the side wall of the hopper, the scraping board is tightly pasted on the end surface of the rotation plate, and the sliding channel is connected with the back end of the scraping board. The utility model has simple structure, so frequent generated noise between the bolt and the feeding hopper does not exist, and because the rotation plate drive is simple, the blocking dead phenomenon of the rotation plate does not happen, additionally, the device skillfully uses the permanent magnet to pick the bolt to make feeding of the bolt simple and reliable, because two sliding grooves are cooperating with the bolt, the bolt lies low in the sliding groove, as long as the sliding groove has relatively small inclination with lateral surface, the bolt can roll forward inside the sliding groove until sticking on the front one, once the bolt is fully arranged inside the sliding groove, the bolt automatically stops moving forward, the entire process can realize automatic and continuous feeding with any auxiliary controlling device.

Description

Screw feeding mechanism

Technical field the utility model relates to arrangement, the conveying machinery of screw.

There are the vibration feeding bucket that resembles introduction in " the automation design " that China Light Industry Press publishes, fan-shaped board-like feeding machanism, linear reciprocating hopper etc. in the present existing Screw feeding of technical background mechanism, saw once in addition that a kind of rotary drum that resembles Waterwheel-type that Japanese PANAVISER the board Screw feeding and the installation system of data introduction are adopted promoted the feed mechanism that screw falls into chute, also had the mechanism of the structure more complicated band Photoelectric Detection that Chinese patent 99235675 provides.Their shortcoming is: fan-shaped board-like feed mechanism and reciprocating type hopper, and screw is standing in chute, leans on the step of screw cap to be bearing in " U " shape chute both sides; Promoting its chute shape of feed mechanism that screw falls into chute with rotary drum also is " U " shape, this class mode is to slide rather than roll in groove because of screw, in order to overcome force of sliding friction, the inclination angle of chute and horizontal surface is quite big, generally be greater than 25 °, like this because of the screw center of gravity not in the perpendicular of the strong point, thereby screw can stack in perk when screw is in osed top groove not, and in enclosed slot the time, the gravity of screw produces moment of torsion, make screw in chute, can not lean on gravity automatically to advancing slip, so often need to enter sealing notch place inside and outside propelling unit (resembling PANAVISETTER comes to this) is set,, also will detects whether should advance spiral nail with a pair of photoelectric switch so that separate screw and stepping propelling screw at screw, this spline structure is quite complicated, involves great expense.

Summary of the invention goal of the invention of the present utility model is improved at the shortcoming in the technical background, and a kind of simple in structure, Screw feeding mechanism cheaply is provided.

The technical solution of the utility model is such: comprise hopper, rotating disk, scraper plate, screw slip lid, feed bin, its turntable is non-permeability magnetic material, on rotating disk, be inlaid with and choose the permanent magnet of inhaling screw, rotating disk places in the hopper side wall rotationally, scraper plate is close to the installation of rotating disk end face, and slideway is accepted mutually with the scraper plate rear end.

The utility model is because simple in structure, the noise that does not exist screw and conveyer bucket frequent vibration to produce, and because rotating disk drives simply, the stuck phenomenon of rotating disk can not take place, so rotating disk can directly be fixed on the motor shaft, do not need anti-jamming and the power-transfer clutch burning motor, install the ingenious permanent magnet that utilizes in addition and choose the suction screw, make the screw charging simple and reliable, because of two chutes and screw coupling, screw lies low at chute, as long as chute and horizontal surface have less inclination, screw just can roll into forward in chute, up to stick previous till, in case screw is arranged full in chute, screw just halts automatically, and whole process does not need any Auxiliary Control Device can realize automatic feeding in continuous material.

Description of drawings

Accompanying drawing 1 is the utility model spatial structure set-up diagram:

Accompanying drawing 2 is Figure 1A-A section-drawings;

Accompanying drawing 3 is Figure 1B-B section-drawings;

Specific embodiment the utility model comprises hopper 1, rotating disk 3, scraper plate 5, screw slip lid 8, feed bin, its turntable 3 is non-magnet materials, on rotating disk 3, be inlaid with and choose the permanent magnet 4 of inhaling screw, rotating disk 3 places in the hopper side wall 2 rotationally, scraper plate 5 is close to the installation of rotating disk 3 end faces, and slideway 8 is accepted mutually with scraper plate 5 rear ends.Described scraper plate 5 is mounted obliquely within on the hopper side wall 2, and is close to rotating disk end face formation V-arrangement slideway, and dock with slideway 8 its rear end.

Described slideway 8 becomes to hold the L face of screw and forms by being installed in a end mill on the hopper side wall 2, and hopper side wall 2 corresponding slideway 8 opening parts have the groove that holds screw head, and slideway 8 is terminal to be docked with feed bin.Described feed bin comprises feed bin body 11 and feed bin lid 10, wherein feed bin body 11 has the T shape chute 12 that holds screw, feed bin lid 10 covers on the T of feed bin body shape chute, make the chute sealing, chute 12 tilts with horizontal surface, the chute mouth of chute 12 higher ends docks with slideway 8, and the low side of feed bin body 11 is established a screw delivery port.

The utility model adopts inlays permanent magnet 4 at non-magnetic transfer dish 2 end faces, transfer dish 2 places the hopper of splendid attire screw interior by driven by motor, be close to transfer dish 2 end faces with horizontal surface bevelled scraper plate 5, one that scraper plate 5 is lower is equipped with chute 8 and chute 12, two chutes and screw form size are complementary, and chute 8 places the V mouth place of scraper plate 5, and chute 2 12 has little inclination with horizontal surface, the other end is low slightly, on have a screw to transport to the outlet of screw mounting machine structure.

Working process of the present utility model is: magnet holds screw during the transfer dish rotation, screw promotes the back with rotating disk and is scraped by scraper plate, V-arrangement slideway along scraper plate and hopper side wall formation glides, and it is parallel with slideway to be oriented to its axis, shown in 6 screws 7 of screw in the accompanying drawing 1, after skidding off the V-arrangement slideway, screw head screw 7 does not backwards enter the chute 1 of baffle plate and hopper side wall formation, directly fall into hopper, screw head screw forward enters baffle plate and hopper side wall and forms a chute 8 (do not enter also directly fall into hopper), again along chute 8 sliding chute mouths through the feed bin upper surface, when row does not expire screw in the chute 12 of feed bin, screw enters in the chute 12 along sliding this mouth, and when row expired screw in the chute 12, screw was not because of entering in the chute 12 interior feeding storehouse upper surface landing hoppers, screw in the landing hopper is picked up by the magnet on the rotating disk again, arrange consistent screw by gravity in the chute 12 and roll toward lower Way out automatically, replenish to output mechanism continuously, realize automatic charging.
