Description

Technical Field

[0001] The present invention relates to the field of mechanical transmission devices, and particularly relates to a traction device for fiberglass profiles. Background Art

[0002] Due to a series of excellent characteristics such as high temperature resistance, corrosion resistance, high strength, low specific gravity, low moisture absorption, small elongation and good insulation, fiberglass profiles have been widely used in industries such as chemical industry, communication and construction in recent years. The fiberglass pultrusion machine for producing fiberglass profiles mainly consists of a yarn rack, a frame, a dipping device, a preheating device, a heating and forming device, a traction device, a sawing device and a finished product rack. After the fiberglass yarn passes through the glue tank from the yarn rack and is impregnated with the resin glue solution, it passes through the yarn plate and the preheating device and then enters the heating and forming device for heating. The fiberglass yarn impregnated with the resin glue solution is cured and formed through the inner cavity of the heating and forming device, and is tightly pulled out by the traction device to become a continuous fiberglass profile. At present, most of the traction devices are two upper and lower transmission chains. The pressing mechanism presses the upper transmission chain, and the fiberglass profile is pulled out between the two upper and lower transmission chains. However, when pulling a large-sized cylindrical fiberglass profile, the existing traction device pulls the fiberglass profile through the line contact between the two transmission chains and the fiberglass profile. When the pressure of the two transmission chains on the fiberglass profile is too small, insufficient traction force cannot be provided, and when the pressure is too large, it is easy to cause the upper and lower sides of the fiberglass profile to deform inward, and the left and right sides of the fiberglass profile to deform outward, thereby reducing the quality of the fiberglass profile. Summary of the Invention

[0003] The purpose of the present invention is to provide a traction device for fiberglass profiles, which has the effect of stably pulling large-sized cylindrical fiberglass profiles.

[0004] The above technical purpose of the present invention is achieved through the following technical solutions: A traction device for fiberglass profiles includes a frame body, at least two traction conveyor belts arranged on the frame body, and a driving motor for driving the traction conveyor belts to rotate. A transmission gap is arranged between adjacent two traction conveyor belts. The traction conveyor belt includes rotating rollers rotatably connected to both ends of the frame body and a traction track sleeved between the two conveyor rollers. A plurality of pressing pads are fixedly connected to the outer surface of the traction track. Traction grooves are respectively arranged on the opposite sides of the pressing pads between adjacent two traction conveyor belts. The frame body is connected with limiting rods respectively located on both sides of the transmission gap.

[0005] By adopting the above technical solution, the fiberglass profile extends into the traction conveyor belt from the transmission gap and the fiberglass profile is embedded into the traction groove. The driving motor drives the traction conveyor belt to move, so that the fiberglass profile is pulled by the traction track and moves along with the traction conveyor belt and extends out from the other end of the traction conveyor belt. The traction groove increases the contact area between the traction track and the fiberglass profile, reduces the force deformation on the upper and lower sides of the fiberglass profile. At the same time, the limiting rods arranged on both sides of the transmission gap limit both sides of the fiberglass profile, further reducing the deformation of the left and right sides of the fiberglass, achieving the effect of stably pulling the large-sized cylindrical fiberglass profile.

[0006] The further setting of the present invention is: a track pressing device is arranged on the frame body. The track pressing device includes a pressing frame slidably connected to the frame body and a driving cylinder for driving the pressing frame to slide. A pressing plate extending into the traction track is fixedly connected to the pressing frame. The traction track is deformed by the thrust of the pressing plate to change the size of the transmission gap.

[0007] By adopting the above technical solution, the driving cylinder drives the pressing plate to move. The pressing plate applies pressure to the inner side of the traction track, so that the upper traction track approaches the lower traction track, tightening the transmission gap to press and fix the fiberglass profile.

[0008] The further setting of the present invention is: the limiting rod includes a limiting seat fixedly connected to the frame body and a limiting cover slidably connected to the limiting seat. An adjusting plate is slidably connected on the limiting seat between the limiting seat and the limiting cover. An adjusting spring is arranged between the adjusting plate and the limiting cover. Both ends of the adjusting spring are fixedly connected to the plate and the limiting cover respectively. A plurality of adjusting shafts are rotatably connected in the limiting seat. An adjusting connecting rod is fixedly connected to the adjusting shaft. A rotating rod is fixedly connected to the adjusting plate. An adjusting sliding groove for the rotating rod to pass through and slide is arranged on the adjusting connecting rod.

[0009] By adopting the above technical solution, when the transmission gap is tightened, the upper limiting cover moves towards the limiting seat under the pressure of the traction track. The adjusting spring is compressed by the force, so that the limiting cover remains in contact with the upper traction track, improving the stability of the setting of the limiting rod, avoiding the deformation of the limiting rod under the force when the transmission gap shrinks, and improving the stability of limiting the fiberglass profile. For fiberglass profiles with different diameters, it is necessary to adjust the width of the transmission gap through the driving cylinder. Rotate the adjusting shaft to drive the adjusting connecting rod to rotate. The rotation of the adjusting connecting rod drives the adjusting plate to slide up and down through the sliding connection between the adjusting sliding groove and the rotating rod, adjusting the protruding height of the limiting cover, so that the limiting rod remains in contact with the traction track, thereby improving the stability of the setting of the limiting rod.

[0010] The further setting of the present invention is: a plurality of positioning parts for restricting the limiting cover from detaching from the limiting seat are connected to the limiting seat, and a plurality of positioning sliding grooves for the positioning parts to extend into respectively are arranged on the side wall of the limiting cover.

[0011] By adopting the above technical solution, the positioning part extends into the positioning slide groove to guide the sliding of the limit cover, while limiting the limit cover from separating from the end of the limit seat, thereby improving the stability of the limit cover setting.

[0012] The present invention is further configured as follows: the limit cover and the adjustment plate are respectively provided with positioning cylinders for the adjustment spring to extend into.

[0013] By adopting the above technical solution, both ends of the adjusting spring extend into the positioning tube, thereby improving the stability of the setting of the adjusting spring.

[0014] The present invention is further configured as follows: two adjacent adjusting shafts are driven by a synchronous belt, and the ends of the adjusting shafts extend out of the frame and are provided with a driving hand wheel.

[0015] By adopting the above technical solution, multiple adjustment shafts are set to adjust the height of the adjustment plate at the same time. The rotation of the driving hand wheel drives the adjustment shaft to rotate. The adjustment shaft drives multiple adjustment shafts to rotate synchronously through belt transmission to adjust the sliding of the adjustment plate, thereby improving the sliding stability of the adjustment plate.

[0016] The present invention is further configured as follows: a connecting sleeve for the adjusting shaft to extend into is provided on the driving hand wheel, a limiting screw is connected to the connecting sleeve, a limiting groove for the end of the limiting screw to extend into and slide along the axial direction of the adjusting shaft is provided on the side wall of the adjusting shaft, a plurality of limiting grooves evenly distributed on the edge of the driving hand wheel are provided on the driving hand wheel, a positioning column extending into the limiting groove is fixedly connected to the frame body, and the driving hand wheel slides along the axial direction of the adjusting shaft to cause the positioning column to disengage from the limiting groove.

[0017] By adopting the above technical solution, when adjusting the extension of the limit cover, loosen the limit screw and ensure that the end of the limit screw is extended into the absorbed slide groove to limit the relative rotation of the connecting sleeve and the adjusting shaft, slide the driving handwheel to make the limit groove disengage from the positioning column, rotate the driving handwheel to adjust the extension of the limit cover, and after the adjustment is completed, slide the driving handwheel axially along the adjusting shaft to make the positioning column extend into the limit groove. The positioning column limits the rotation of the adjusting column, and tighten the limit screw to limit the axial sliding of the driving handwheel.

[0018] The present invention is further configured as follows: one end of the limit rod close to the two traction crawlers is rotatably connected to a plurality of rolling shafts.

[0019] By adopting the above technical solution, multiple rolling shafts are rotatably connected on the upper and lower sides of the limit rod, and the sliding friction between the traction track and the limit rod is converted into rolling friction between the traction track and the rolling shaft, thereby reducing the friction between the limit rod and the traction track.

[0020] The beneficial effects of the present invention are:

[0021] 1. A traction groove is provided on the outer surface of the traction track, and limit rods are provided on both sides of the transmission gap. The traction groove increases the contact area between the traction track and the fiberglass profile, reduces the force-induced deformation on the upper and lower sides of the fiberglass profile. At the same time, the limit rods provided on both sides of the transmission gap limit the two sides of the fiberglass profile, achieving the effect of stably towing a large-sized cylindrical fiberglass profile;

[0022] 2. The limit rods are set as a limit seat and a limit cover that are slidably connected to each other, and an adjustment spring is provided between the adjustment plate and the limit cover. When the transmission gap tightens, the limit cover slides into the limit seat, preventing the limit rod from being deformed by force when the transmission gap contracts and improving the stability of limiting the fiberglass profile;

[0023] 3. By rotating the adjustment shaft, the adjustment link drives the adjustment plate to slide up and down. The adjustment plate adjusts the height of the adjustment cover protruding from the limit seat through the adjustment spring connected to the limit cover, ensuring the mutual contact between the limit cover and the traction track, improving the stability of the setting of the limit rod, and enhancing the stability of limiting during the towing of the fiberglass profile.
