Description

Technical Field

[0001] This utility model relates to the field of straightening equipment technology, specifically to a straightening device for fiber-reinforced polypropylene sheets. Background Technology

[0002] Polypropylene fiber cloth composite board is a thermoplastic resin composite material with polypropylene as the matrix. It adopts a laminated structure design to improve mechanical properties. Therefore, it may bend after production, making it unusable. A straightening structure is required to correct it. However, the existing straightening structure is to achieve straightening by pressing two parallel steel plates, etc. However, this method of straightening cannot resist the restoring force of the structure, so the straightened board still has slight bending, which has certain problems. To address this issue, a fiber-reinforced polypropylene board straightening device is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A fiber-reinforced polypropylene sheet straightening device includes a heating mechanism, a pressing mechanism, and an auxiliary mechanism. The heating mechanism includes a supporting shell, a connecting rod fixedly installed in the middle of the inner cavity of the supporting shell, a heat-conducting plate movably sleeved on the connecting rod, a fan disposed in the middle of the supporting shell, and a heater fixedly installed at the bottom of the fan. The pressing mechanism includes a supporting rod fixedly installed on the top of the supporting shell, a top plate fixedly installed on the top of the supporting rod, a sliding rod inserted into the top plate, a side pressure plate fixedly installed on the bottom of the sliding rod, a connecting frame fixedly connected to the top of the sliding rod, a hydraulic component for driving the connecting frame to rise and fall, and a middle pressure plate disposed at the bottom of the sliding rod in the middle. The auxiliary mechanism includes a fixed rod fixedly installed on the side of the inner cavity of the supporting shell and a side top plate fixedly connected to the top of the fixed rod.

[0006] Preferably, limit rods are fixedly installed in the inner cavity of the support shell at positions on both sides of the fan.

[0007] Preferably, connecting rods are fixedly installed on both sides of the side pressure plate, and a sliding sleeve is fixedly connected to the middle of the connecting rod, and the sliding sleeve is slidably connected to the support rod.

[0008] Preferably, there are four sliding rods, with the bottom ends of the two middle sliding rods fixedly connected to the top of the intermediate pressure plate.

[0009] Preferably, the supporting shell is slidably connected to the inner cavity of the supporting shell.

[0010] Preferably, both the connecting rod and the fixing rod are fitted with springs.

[0011] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0012] In this invention, the heat-conducting plate is slidably connected inside the supporting shell and restricted by a limiting rod, allowing it to descend only slightly. The height of the side top plate is fixed, so the two sides of the plate are slightly lifted. Therefore, when the side pressure plate and the middle pressure plate rise and no longer press, the upturn on both sides will resist the restoring elasticity, ensuring the straightening effect and improving the practicality of the device. A fan is set below the middle of the heat-conducting plate to heat the middle of the heat-conducting plate, thereby achieving shaping and improving the reliability of the device.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of a fiber-reinforced polypropylene sheet straightening device provided by this utility model.

[0021] Example:

[0022] Combination Figure 1-2As shown, the present invention provides a fiber-reinforced polypropylene sheet straightening device, including a heating mechanism, a pressing mechanism, and an auxiliary mechanism. The heating mechanism includes a supporting shell 110, a connecting rod 120 fixedly installed in the middle of the inner cavity of the supporting shell 110, a heat-conducting plate 130 movably sleeved on the connecting rod 120, a fan 140 disposed in the middle of the supporting shell 110, and a heater 150 fixedly installed at the bottom of the fan 140. Limiting rods 111 are fixedly installed in the inner cavity of the supporting shell 110 at positions on both sides of the fan 140. The supporting shell 110 is slidably connected to the inner cavity of the supporting shell 110. The pressing mechanism includes a supporting rod 210 fixedly installed on the top of the supporting shell 110, a top plate 220 fixedly installed on the top of the supporting rod 210, and a sliding rod 220 inserted into the top plate 220. 30. A side pressure plate 240 fixedly installed at the bottom of the sliding rod 230, a connecting frame 250 fixedly connected to the top of the sliding rod 230, a hydraulic component 260 for driving the connecting frame 250 to rise and fall, a central pressure plate 270 set at the bottom of the middle sliding rod 230, connecting rods 280 fixedly installed on both sides of the side pressure plate 240, a sliding sleeve 290 fixedly connected to the middle of the connecting rod 280, the sliding sleeve 290 slidably connected to the support rod 210, the number of sliding rods 230 is four, the bottom ends of the two middle sliding rods 230 are fixedly connected to the top of the central pressure plate 270, the auxiliary mechanism includes a fixed rod 310 fixedly installed on the side of the inner cavity of the support housing 110, a side top plate 320 fixedly connected to the top of the fixed rod 310, and springs are sleeved on both the connecting rod 120 and the fixed rod 310.

[0023] Specifically, the side pressure plate 240 is used to press the side to prevent the side from lifting when the middle pressure plate 270 is pressed down, thus improving the reliability of the structure. At the same time, the connecting frame 250 is used to synchronize the side pressure plate 240 and the middle pressure plate 270, thus avoiding straightening failure due to structural asynchrony and improving the practicality of the device.

[0024] In addition, the connection of connecting rod 280 and sliding sleeve 290 ensures that the side pressure plate 240 and the middle pressure plate 270 are pressed down stably, avoiding deviations in the pressing process of the side pressure plate 240 and the middle pressure plate 270, and ensuring the reliability of the structure.

[0025] The working principle and usage process of this utility model are as follows: First, place the polypropylene sheet to be straightened on the heat-conducting plate 130, start the hydraulic component 260, drive the connecting frame 250 to descend, thereby driving the side pressure plate 240 and the middle pressure plate 270 to press down, straightening the bent part of the polypropylene sheet. At the same time, since the height of the side top plate 320 is fixed, while the position of the heat-conducting plate 130 can be slightly pressed down, the two sides will be excessively pushed up to resist the rebound. Finally, the straightened polypropylene sheet can be removed.

[0026] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
