Abstract

The utility model relates to a reciprocating-type transmission box of a single screw extruder. The transmission box comprises a box body, wherein a driving wheel and a driven wheel are arranged in the box body, the driven wheel is a plane cam, a screw rod sleeve is fixedly connected in a center shaft hole of the driven wheel, and the portion, on the two sides of the driven wheel, of the box body is further provided with a limiting roller for limiting the left and right swing amplitude of the driven wheel. A fastener used for fixing the screw rod sleeve is arranged in the center shaft hole of the driven wheel. According to the transmission box, the transmission function and the swing function are integrated, a screw rod can rotate, meanwhile, the screw rod can make axial reciprocating motion, and the transmission box is simple in structure and high in reliability.

Description

A kind of transmission case of reciprocating single-bolt extruder

Technical field

The utility model relates to reciprocating single-bolt extruder, is specifically related to a kind of transmission case of reciprocating single-bolt extruder.

Background technique

Common reciprocating single-bolt extruder, when rotating in order to realize screw rod, also carries out axial to-and-fro motion, conventionally all will be simultaneously by a gear-box and one are installed, waves case.Gear-box is responsible for specially as screw rod rotation provides power, and wave case, is responsible for the front-rear reciprocation movement of realizing screw rod specially.

The extruder transmission device of said structure obviously has the defect that complex structure, reliability are not high.

Model utility content

The utility model aims to provide a kind of transmission case that integrates the reciprocating single-bolt extruder of transmission and swing function, and it is simple in structure, reliability is high.

Technical solution adopted in the utility model is as follows:

A transmission case for reciprocating single-bolt extruder, comprises casing, is provided with a driving wheel and a follower in described casing; Described follower is a face cam, is connected with a screw sleeve in the central shaft hole of this follower; On the casing of described follower both sides, be also respectively provided with one and limit the swing limited roller of amplitude of this follower.

In the central shaft hole of described follower, be provided with the fastening piece for fixing described screw sleeve.

The utility model is by the motion of a face cam, make extruder screw stably when radially rotating, also can be reciprocating vertically, and without as previous extruder, adopt the different mechanism of two covers realize respectively the rotation of screw rod and seesaw.Compared to same category of device before, the utility model structure is simpler, and reliability is also higher.

In figure, be labeled as: 1, casing, 2, driving wheel, 3, follower, 4, screw sleeve, 5, limited roller, 31, (follower) central shaft hole, 32, fastening piece.

Embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described.

With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4:

A transmission case for reciprocating single-bolt extruder, comprises casing 1, is provided with a driving wheel and a

follower

2,3 in described casing 1; Described follower 3 is a face cam, is connected with a screw sleeve 4 in the central shaft hole 31 of this follower 3;

On the casing 1 of described follower 3 both sides, be also respectively provided with one and limit the swing limited roller 5 of amplitude of this follower 3.

In the central shaft hole 31 of described follower 3, be provided with the fastening piece 32 for fixing described screw sleeve 4.

When driving wheel 2 drives follower 3 to rotate, because follower 3 is a face cam, it rotates hour wheel cognition and with the limited roller 5 of being located at both sides, bottom, touches successively respectively: when the limited roller 5 on its left side wheel body and its left side is touched, wheel face tilts to the right, drives the screw sleeve 4 in its central shaft hole 31 to retreat;

When the limited roller 5 on its right side wheel body and its right is touched, wheel face tilts to the left, drives the screw sleeve 4 in its central shaft hole 31 to protract, and so repeat left and right, can make screw sleeve 4 in constantly rotation, also does axial to-and-fro motion.

Claims

1. a transmission case for reciprocating single-bolt extruder, comprises casing (1), is provided with a driving wheel and a follower (2,3) in described casing (1); It is characterized in that, described follower (3) is a face cam, in the central shaft hole (31) of this follower (3), is connected with a screw sleeve (4); On the casing (1) of described follower (3) both sides, be also respectively provided with one and limit the swing limited roller (5) of amplitude of this follower (3).

2. the transmission case of a kind of reciprocating single-bolt extruder according to claim 1, is characterized in that, is provided with the fastening piece (32) for fixing described screw sleeve (4) in the central shaft hole (31) of described follower (3).
