Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment 1:

A kind of more feeding devices of extruder, such as Fig. 1, including be arranged on 1 side wall of feed hopper three transfer tubes 11, turn The dynamic transmission screw rod 12 being connected in transfer tube 11, the shape that 1 upper end side wall of feed hopper surrounds are rectangle, and three transfer tubes 11 divide Not on the different side wall of feed hopper 1, one end of transfer tube 11 enters feed hopper 1, the transmission screw rod 12 in transfer tube 11 One end extend one end that transfer tube 11 is located at feed hopper 1, the other end is driven by the motor 21 being fixed on body 2, transmission Pipe 11 is equipped with the charging box 111 that is connected to transfer tube 11, and different materials is poured into different charging boxes by operator when use In 111, each transmission screw rod 12 is by material transferring to feed hopper 1 at this time, in realization feed hopper 1 while different material Conveying, and transmit each material of transmission that screw rod 12 can quantify.

Such as Fig. 2, when transmitting screw rod 12 and gradually transmitting the material fed in box 111 into feed hopper 1, if charging box Material in 111 is more, and then causes the accumulation of material in charging box 111 and material is mutually bonded, and is feeding at this time It is rotatably connected in box 111 and stretches out charging box 111 with the parallel bull stick 112 of transmission screw rod 12, one end of bull stick 112, such as Fig. 3, Bull stick 112 is respectively connected with driven gear in one end far from feed hopper 1 in the one end and transmission screw rod 12 for stretching out charging box 111 113, the shaft of motor 21 is equipped with the driving gear 22 engaged respectively with two driven gears 113, and transfer tube 11 is equipped with cover Protective cover 116(such as Fig. 1 outside driven gear 113 and driving gear 22), 112 outer wall of bull stick is circumferentially with several stirring rods 114, the distance between bull stick 112 and transmission screw rod 12 are greater than the length of stirring rod 114.When material is more, can also will pass Defeated screw rod 12 is set as intermeshing two, as long as being at this time disposed therein driven gear 113 on a transmission screw rod 12 i.e. Can, convenient for transmitting more materials.

Such as Fig. 3, motor 21 when driving transmission screw rod 12 transmits material into feed hopper 1, by driving gear 22 and from The engagement and then the drive rotation of bull stick 112 of moving gear 113, so that bull stick 112 drives stirring rod 114 to rotate in charging box 111, Material is stirred, the bonding of material is reduced, so that material is easy to be transmitted screw rod 12 and transmits, it is furthermore L-type, L-type by stirring rod 114 The both ends of stirring rod 114 pass through support rod 115 and connect, and L-type stirring rod 114 and support rod 115 together form triangle, surely It is qualitative good, reduce the deformation of stirring rod 114 and increase the contact area of stirring and material, allow more materials by It is stirred to.

Such as Fig. 1, the box wall for feeding box 111 is equipped with the observation window 119 of waist type, height of the observation window 119 along charging box 111 Directional spreding, and it is equipped with transparent glass plate 1191 in observation window 119, material in charging box 111 is observed convenient for operator How much, the inner wall of glass plate 1191 towards the one side and charging box 111 of charging box 111 is in the same plane, reduces material It is accumulated in observation window 119.

As Fig. 2 needs to feed remaining in box 111 when charging box 111, which needs replacing different materials, to be transmitted Material discharge is equipped with discharge gate 117 in the sidewall bottom of charging box 111 at this time, feeds and be plugged with closing discharge gate 117 on box 111 Sealing-plug 1171, the section of feed inlet is rectangle, and feed inlet reduces material accumulation close to the bottom setting of charging box 111 In charging box 111, the cleaning piece 118 that remaining material in box 111 is discharged to discharge gate 117 will be fed by being equipped in charging box 111 (such as Fig. 1).

Such as Fig. 1, cleaning piece 118 includes being provided with charging box 111 relative to the air inlet 1181 on the side wall of discharge gate 117 (such as Fig. 3), body 2 be equipped with air blower 1182, the gas outlet of air blower 1182 be connected with lead to each air inlet 1181 into Wind hose 1183 is equipped with shut-off valve 1184 on each air inlet hose 1183, and shut-off valve 1184 is not required to each charging box 111 It to clear up simultaneously, operator can be made to clear up charging box 111 as needed.

As Fig. 2 in order to reduce material spilling near body 2, therefore feeds box when material is discharged from discharge gate 117 111 are placed with rewinding box 23 in the side of discharge gate 117, and rewinding box 23 can be placed on body 2, the box mouth court of rewinding box 23 To discharge gate 117, the plate 24 of closing 23 box mouth of rewinding box is plugged in the box wall of rewinding box 23, when plate 24 is by rewinding box 23 Box mouth closing when plate 24 be equipped with the drainage conduit 25 of face discharge gate 117, rewinding box 23 is moved to discharge gate by operator 117, so that drainage conduit 25 and discharge gate 117 contradict, the internal diameter of drainage conduit 25 is greater than the aperture of discharge gate 117, is convenient for discharge gate 117 material fully enters in drainage conduit 25.

Specific operation process: different materials is put into different charging boxes 111 by operator, and transmission screw rod 12 will be fed In material transferring to feed hopper 1 in box 111, charging while realizing different material in feed hopper 1 at this time.When needing replacing When feeding the material in box 111, corresponding shut-off valve 1184 is opened, starts air blower 1182, so that the wind of air blower 1182 Entered in charging box 111 by air inlet hose 1183, opens sealing-plug 1171, rewinding box 23 is mobile to charging 111 direction of box, Until the drainage conduit 25 and discharge gate 117 on plate 24 contradict, so that the material being discharged out of discharge gate 117 enters rewinding box 23 It is interior, it realizes the recycling of material, reduces the waste of material.

Embodiment 2: a kind of extruder, including above-described embodiment 1.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
