Description

Technical Field

[0001] The utility model belongs to the field of traction machine equipment, in particular to a double-crawler traction machine for pultrusion. Background Art

[0002] At present, single crawlers are commonly used in the market, which can only produce one composite product, or the traction machine is widened to ensure that the traction machine can clamp multiple composite products at the same time. When producing one product, the production efficiency is low; when producing multiple composite products at the same time, the efficiency is greatly improved, but when one product has an abnormality and needs to be shut down, the entire traction machine needs to stop working, and the production of other products can only be stopped; if other products can still be produced normally, the abnormal traction of the product is stopped, which is easy to cause asymmetric clamping during traction and compaction, causing certain damage to the traction machine structure. Moreover, when clamping multiple composite products at a time, slippage is likely to occur, resulting in products of different lengths and an increase in scrap rate.

[0003] The common ones in the market now are using a single set of motor reducers, which transmit power to the lower traction frame through chain transmission, and then use the gear box and universal coupling structure to transmit power to the upper traction frame. Through gear transmission, the upper traction frame is linked with the lower traction frame to ensure the synchronous operation of the upper and lower traction frames. This structure requires many parts, and there are more failure points and maintenance points. In addition, the universal coupling and gear box require a certain amount of installation space, resulting in a wider equipment width. If it is made into a multi-head traction mechanism, the equipment width will increase exponentially, and the equipment occupancy area will increase. Utility Model Content

[0007] Preferably, the upper and lower traction frames have the same structure, one end of the traction frame is equipped with a power transmission mechanism, and the other end of the traction frame is equipped with a driven transmission mechanism.

[0008] Preferably, the power transmission mechanism is connected to the lower traction frame via a flange, and the driven transmission mechanism adjusts the transmission chain via an adjusting bolt.

[0009] Preferably, the transmission chain is a large-sized double-row chain, and the clamping cylinder adopts a plurality of large-diameter cylinders.

[0010] Preferably, the pressing block is formed by integrally casting high-hardness polyurethane and a high-strength metal matrix.

[0011] Preferably, the support guide shaft is made of high-quality carbon structural steel.

[0012] Preferably, there are four clamping cylinders, four sets of motor reducers, and two sets of upper and lower traction frames.

[0013] Preferably, four transmission chains are provided, a plurality of pressing blocks are provided, and two ejection cylinders are provided.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. This traction machine adopts the structure of upper and lower crawler clamping transmission. The upper and lower traction crawlers are powered separately, and the frequency conversion control system is used to control the upper and lower motors at the same time. Since the upper and lower traction crawlers are powered separately, the electrical control system can realize the synchronous control of the upper and lower crawlers, eliminating the complex mechanical mechanism for realizing synchronous transmission. The overall structure of the equipment becomes simple and concise, reducing the reduction of transmission efficiency caused by mechanical friction. While improving the transmission efficiency, it also reduces the equipment's failure points and later equipment maintenance. In addition, this traction machine is a one-machine multi-head traction structure, and each traction machine is controlled separately without affecting each other. Multiple products can be produced at the same time, greatly improving production efficiency; due to the control method of the frequency conversion servo control system, the structure is simple, the equipment size is smaller than that of the traditional structure, the workshop production line occupies a small area, and the production cost is low; at the same time, it is easy to operate and has a high degree of automation. The clamping cylinder and the ejection cylinder are installed in separate air circuits, and each set of traction mechanism is controlled separately through a separate solenoid valve control program.

[0016] 2. The frame is welded and formed by large-size carbon steel profiles. The structure is simple and reasonable, with high strength and a base plate at the bottom, which is convenient for leveling and fixing the equipment. The upper and lower traction frames are respectively equipped with motor reducers. The motor reducers only need to be installed on the power transmission end of the upper and lower traction machines through flanges. This structure can greatly reduce the width of the equipment. The friction between the polyurethane block and the composite material is large and has a certain elasticity, which can achieve the clamping and traction of the composite material. The surface of the block is provided with diamond-shaped grooves, which improves the grip of the block on the composite material and effectively reduces the slippage between them.
