Description

Technical Field

[0001] The utility model belongs to the field of fiber reinforced composite material pultrusion, and relates to an automatic meter counting device for fixed length of products, in particular to an automatic meter counting device for pultrusion. Background Art

[0002] The fiber reinforced composite pultrusion process is a thermosetting composite molding method. The raw materials include a resin matrix and a reinforcing material. The reinforcing material is mixed with the resin matrix and then heated in a mold. After the mold is heated, it is cured and formed, and then the product is pulled out of the mold by a traction machine.

[0003] Since the process is an online continuous pultrusion, the product needs to be cut into profiles of a certain length according to needs. At this time, the product needs to be measured and cut with a cutting saw when it reaches the set length.

[0004] The automatic metering device is very important in the composite material pultrusion process, which determines the length accuracy of the product cut. If the cutting length does not reach the required length of the profile, it will cause waste or even unqualified products.

[0005] The metering device usually uses a rotary encoder and a meter wheel structure for length control. The metering accuracy of this structure is directly related to the quality of the rotary encoder, the molding process and processing accuracy of the meter wheel. In this device, the encoder adopts an internationally renowned brand with a high pulse number; it has high accuracy and stable performance; the meter wheel and roller adopt high-quality polyurethane rubber casting technology, and the outer circle is ground after CNC turning to ensure the accuracy of the outer diameter of the meter wheel. A roller mechanism is installed at the lower end of the metering device, which can provide strong support for the product. The upper metering mechanism can ensure that the meter wheel is always pressed on the surface of the product through the tension spring to avoid jumping or detaching from the product during the metering process.

[0006] At the same time, the meter correction coefficient is set in the program. Since the meter device cannot completely achieve zero error metering, the meter correction coefficient in the program can be adjusted to reduce the meter error and minimize the meter length error.

[0007] Due to the characteristics of the pultrusion process, the product will be affected by multiple factors during the production process, and slippage may occur. If it is not discovered and handled in time, it is likely to cause downtime, resulting in failure to produce normally, waste and affecting the construction period. At this time, the encoder can be used to measure the speed through the program, and the speed measured by the encoder can be compared with the running speed of the equipment, and the difference can be set. When the difference exceeds the set value, the equipment will alarm. This is conducive to the control and optimization of the pultrusion production process.

[0008] The existing meter counting device has a low-priced rotary encoder with poor quality. The meter wheel molding process has defects, and the outer circle size processing accuracy cannot be guaranteed. There is no support mechanism at the bottom, which causes the product to jump up and down frequently during the length counting process. When the product slips during the production process, it cannot be discovered and adjusted in time, resulting in downtime, which causes waste and affects production efficiency.
