Description

Technical Field

[0001] This utility model belongs to the field of epoxy resin fiberglass board processing technology, specifically relating to an epoxy resin fiberglass board production pressing device. Background Technology

[0002] Epoxy resin fiberglass board is a composite board material with epoxy resin as the matrix and fiberglass cloth as the reinforcing material. The two are combined through a hot pressing process to form a high-strength, high-insulation laminate.

[0003] The epoxy resin fiberglass board production pressing device is the core equipment used to bond epoxy resin with fiberglass cloth, forming the board through heating and pressure. Its design must take into account both material properties and process requirements. The pressing device uses hot pressing technology to cure the pre-impregnated epoxy resin fiberglass cloth under high temperature and pressure. When heated, the resin softens and flows, filling the gaps between fibers to form a uniform adhesive layer, and chemical bonding is achieved through molecular chain diffusion.

[0004] During the pressing process, existing epoxy resin fiberglass boards are prone to interlayer slippage under high pressure due to insufficient interlayer friction of the prepreg or poor mold positioning accuracy. This results in defects such as misalignment of the fiber cloth and resin matrix, and uneven local thickness. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6The present invention provides the following technical solution: an epoxy resin fiberglass board production pressing device, including a pressing assembly 100, including a pressing base 101 provided at the bottom for support, a bracket 102 installed on the upper surface of the pressing base 101, a pressing cylinder 103 installed on the inner wall of the bracket 102, and a pressing plate 104 installed on the movable end of the pressing cylinder 103. The side baffle assembly 200 includes a side baffle portion 201 installed inside the pressing base 101 and extending to the outside, a drive portion 202 disposed inside the cavity of the pressing base 101 and connected to the bottom side of the side baffle portion 201, a first adjustment portion 203 connected to the bottom side of the pressing base 101 and connected to the pressing base 101, and a guide portion 204 connected to the side surface of the side baffle portion 201 and connected to the inner wall of the pressing base 101. The front windshield assembly 300 includes a first telescopic rod 301 installed inside the cavity of the pressing base 101, a first horizontal plate 302 connected to the movable end of the first telescopic rod 301, and a front windshield rod 303 that penetrates the upper surface of the pressing base 101 and is connected to the first horizontal plate 302. The rear bumper assembly 400 includes a rear bumper portion 401 formed on the upper surface of the pressing base 101 and a second adjustment portion 402 connected to the lower surface of the rear bumper portion 401 and connected to the inner wall of the pressing base 101.

[0019] In use, the epoxy resin fiberglass board is placed on the upper surface of the pressing base 101. Then, the pressing cylinder 103 can be controlled to run. When the pressing cylinder 103 runs, it can drive the pressing plate 104 to move downward. When the pressing plate 104 moves downward to the surface of the epoxy resin fiberglass board, the epoxy resin fiberglass board can be pressed by the pressing plate 104.

[0020] Preferably, the side stop 201 includes a mounting plate 201a disposed inside the cavity of the pressing base 101, a first bearing 201b fitted inside the mounting plate 201a, a rotating shaft 201c that passes through and connects inside the first bearing 201b, and a side stop bar 201d connected to the top of the rotating shaft 201c.

[0021] In practical use, the side stops 201d can restrict the two sides of the epoxy resin fiberglass board to be pressed, thus preventing the epoxy resin fiberglass board from shifting to the sides during pressing.

[0022] Preferably, the drive unit 202 includes a pulley 202a connected to the end of the rotating shaft 201c, a belt ring 202b sleeved on the surface of the pulley 202a, and a first drive motor 202c connected to the end of the rotating shaft 201c and mounted on the bottom side of the mounting plate 201a.

[0023] In practical use, when the first drive motor 202c runs, it can drive the rotating shaft 201c connected to it to rotate. When the rotating shaft 201c rotates, it can drive the side stop 201d connected to it to rotate. At the same time, when the rotating shaft 201c rotates, it drives another rotating shaft 201c to rotate through the pulley 202a and belt ring 202b. Thus, the other side stop 201d can be driven to rotate through the other rotating shaft 201c, thereby realizing that the side stop 201d can rotate at the same time.

[0024] Preferably, the first adjustment unit 203 includes a connecting plate 203a connected to the bottom side of the mounting plate 201a, an internal threaded tube 203b that penetrates and is connected inside the connecting plate 203a, a bidirectional lead screw 203c that penetrates and is adapted to the internal threaded tube 203b, a second bearing 203d that is sleeved on the surface of the bidirectional lead screw 203c and mounted on the side surface of the pressing base 101, and a second drive motor 203e that is connected to the end of the bidirectional lead screw 203c and mounted on the side surface of the pressing base 101.

[0025] In practical use, when the second drive motor 203e is running, it can drive the bidirectional lead screw 203c to rotate inside the second bearing 203d. When the bidirectional lead screw 203c rotates, it can drive the two internal threaded tubes 203b to move axially in the opposite direction. The movement of the two internal threaded tubes 203b can drive the two connecting plates 203a to move axially in the opposite direction. The axial movement of the two connecting plates 203a can drive the side stop 201 to move axially in the opposite direction, thereby adjusting the distance between the two sets of side stop rods 201d.

[0026] Preferably, the guide portion 204 includes a first sliding sleeve 204a connected to both ends of the mounting plate 201a and a first slide rail 204b connected to the inner wall of the pressing base 101 and adapted to the first sliding sleeve 204a.

[0027] In practical use, when the mounting plate 201a is subjected to a force, it can drive the first sliding sleeve 204a to slide on the surface of the first slide rail 204b, which can limit the movement direction of the mounting plate 201a.

[0028] Preferably, the rear stop 401 includes a groove 401a formed on the surface of the pressing base 101, a rear stop bar 401b passing through the inside of the groove 401a, and a second horizontal plate 401c disposed inside the cavity of the pressing base 101 and connected to the bottom of the rear stop bar 401b.

[0029] In practical use, when the second horizontal plate 401c is subjected to a force, it can drive the rear stop 401b to slide inside the slide groove 401a, thus adjusting the position of the rear stop 401b.

[0030] Preferably, the second adjustment part 402 includes a second slide rail 402a connected to the inner wall of the pressing base 101, a second slide sleeve 402b sleeved and adapted to the surface of the second slide rail 402a, a second telescopic rod 402c installed on the upper surface of the second slide sleeve 402b and connected to the second cross plate 401c, and a third telescopic rod 402d installed on the inner wall of the pressing base 101 and connected to the second slide sleeve 402b.

[0031] In practical use, when the second telescopic rod 402c retracts, it can drive the rear stop 401b to move downward through the second horizontal plate 401c, thereby adjusting the height of the rear stop 401b.

[0032] It should be noted that, in its original state, the top of the rear derailleur 401b is flush with the upper surface of the press-fit base 101.

[0033] Working principle: When using the epoxy resin fiberglass board production pressing device, the second drive motor 203e can be controlled to run. When the second drive motor 203e runs, it can drive the bidirectional lead screw 203c to rotate. When the bidirectional lead screw 203c rotates, it can drive the connecting plate 203a to move axially in the opposite direction through the internal thread tube 203b. When the connecting plate 203a moves, it can drive the side stop 201 to move horizontally downward, thereby adjusting the distance between the two sets of side stop rods 201d to adapt to epoxy resin fiberglass boards of different widths. Next, the end of the epoxy resin fiberglass board is placed between the two sets of side stops 201d. Then, the first drive motor 202c can be run. When the first drive motor 202c runs, it can drive multiple side stops 201d to rotate simultaneously through the pulley 202a, belt ring 202b and rotating shaft 201c. When the side stops 201d rotate, the epoxy resin fiberglass board can be loaded. When the front end of the epoxy resin fiberglass board moves to one side of the front stop 303, the second telescopic rod 402c can be operated. When the second telescopic rod 402c extends, it can drive the rear stop 401b to move upward through the second horizontal plate 401c. Then the third telescopic rod 402d can be operated. When the third telescopic rod 402d retracts, it can drive the second sliding sleeve 402b to slide laterally on the surface of the second slide rail 402a. When the second slide rail 402a slides, it can move laterally through the second telescopic rod 402c, the second horizontal plate 401c and the rear stop 401b. When the rear stop 401b moves laterally to the rear end of the epoxy resin fiberglass board, it prevents the epoxy resin fiberglass board from shifting during the pressing process. Next, the first telescopic rod 301 can be operated. When the first telescopic rod 301 retracts, it can drive the front stop 303 to move downward through the first horizontal plate 302. When the front stop 303 moves to be flush with the upper surface of the pressing base 101, the material can be unloaded by rotating the side stop 201.

[0034] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
