Abstract
The utility model discloses a film extrusion speed detection device of a double-screw extruder, which is characterized in that the detection device includes a floating roller (1) arranged on a frame (8) through a connecting rod (2) and a bearing pedestal (3), and a device arranged on the bearing base (3) for detecting the swing angle of the connecting rod. The film extrusion speed detection device has a simple structure, and an angle deflection signal can be fed back to a PLC for programmable control by a deflection detection, so that the receiving and hanging speed of a film cooling device is automatically controlled to be kept consistent to the film extrusion speed of the extruder.
Description
Technical field:
The utility model relates to a kind of double screw extruder, specifically a kind of film extruded velocity checkout gear.
Background technology:
The rubber double screw extruder is extruded into sizing material continuous film and sends into batch off unit.Because the sizing material of piling up in the speed that double screw extruder is extruded film and the extruder is relevant, the sizing material of accumulation is many, just need to improve extruded velocity, otherwise that sizing material is piled up is few, just needs to reduce extruded velocity, with the successive sheet of assurance slice.Therefore, extruder is extruded the speed of film and the kiss-coating speed that accesses of batch off unit is difficult to be consistent, and usually produces continuously because of inconsistent interruption the between slice speed two machines easily.
Summary of the invention:
The purpose of this utility model provides a kind of checkout gear of double screw extruder film extruded velocity.
The utility model is to adopt following technical scheme to realize its goal of the invention, and a kind of film extruded velocity checkout gear is provided with by connecting rod, the rack-mounted dancer of bearing block, and bearing block is provided with the checkout gear of connecting rod swing angle.
The checkout gear of connecting rod swing angle described in the utility model comprises the following synchronous pulley that is installed on the bearing block, and last synchronous pulley is connected with following synchronous pulley by being with synchronously, is connected with the displacement detector on the last synchronous pulley.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, by the displacement detector with the angular deflection signal feedback to PLC control able to programme, thereby reach the kiss-coating speed that accesses of automatic control batch off unit and speed that extruder is extruded film is consistent.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing.As seen from Figure 1, Figure 2, a kind of film extruded velocity checkout gear is provided with by connecting rod 2, bearing block 3 and is installed in dancer 1 on the frame 8 of extruder, and bearing block 3 is provided with the checkout gear of connecting rod swing angle.
The checkout gear of connecting rod swing angle described in the utility model comprises the following synchronous pulley 4 that is installed on the bearing block 3, and last synchronous pulley 7 is connected with displacement detector 5 by being with 6 to be connected with following synchronous pulley 4 synchronously on the last synchronous pulley 7.
In the utility model when work,, the film that extruder is extruded is held the roller frame and is driven dancer 1 in the roller frame.When extruder is extruded speeding up of film, connecting rod 2 will along film extrude direction (as A among Fig. 2 to) swing certain angle, thereby by the following synchronous pulley 4 on the bearing block 3, be with 6 synchronously, go up synchronous pulley 7, make the displacement detector produce the respective corners displacement, the displacement detector to PLC control able to programme, is controlled the angular deflection signal feedback automatically the kiss-coating speed that accesses of batch off unit and speed that extruder is extruded film and is consistent.
