[0021] In the first aspect of the present invention, a pultrusion device for the production of glass fiber composite materials is proposed, as Figures 1 to 3 shown, which includes a clamp 1. There are two clamps 1, which are divided into a main clamp 1 and a sub - clamp 1. The pultrusion device further includes an opposite movement control mechanism 2 for driving the opposite movement between the main clamp 1 and the sub - clamp 1. A movable brush roller 3 is arranged on the clamp 1, and the brush roller 3 is used to remove the contaminants on the clamping surface of the clamp 1.

[0022] As Figure 3 shown, further: The clamp 1 includes a base 11 and a top frame 12. The base 11 is distributively provided with first guide rods 111, and the top surface of the base 11 has a bottom clamping surface.

[0023] As Figure 2 shown, furthermore: The pultrusion device includes a translation control mechanism 4. The translation control mechanism 4 includes a connecting frame 41. A second guide rod 42 and a threaded rod 43 are provided on the top frame 12. The second guide rod 42 is fixedly connected to the top frame 12, and the second guide rod 42 is slidably connected to the connecting frame 41.

[0024] The first rotary driver 44 is a stepping motor, and synchronous wheels are respectively arranged on the threaded rod 43 and the output shaft of the stepping motor and are connected by a synchronous belt.

[0025] As Figure 7 shown, furthermore: The brush roller 3 includes a roller shaft 31, and a keyway is provided on the roller shaft 31. The brush roller 3 further includes a roller barrel 32. A convex strip corresponding to the keyway is provided on the inner wall of the roller barrel 32, and bristles are covered on the outer wall of the roller barrel 32.

[0026] The material of the bristles can be natural hair such as pig hair, horse hair, etc., or synthetic fibers such as nylon, polypropylene, etc., but not limited thereto.

[0027] As Figure 4 shown, furthermore: The pultrusion device includes a fixed seat 5. A bearing seat 51 is provided at one end of the fixed seat 5, and one end of the roller shaft 31 is rotatably connected to the bearing seat 51; An anti - detachment mechanism 53 is provided at the other end of the fixed seat 5 for preventing the roller barrel 32 from detaching from the roller shaft 31; A second rotation mechanism is provided on the fixed seat 5 for driving the roller shaft 31 to rotate.

[0028] The second rotary driver 52 is a stepping motor, and synchronous wheels are respectively arranged on the roller shaft 31 and the output shaft of the stepping motor and are connected by a synchronous belt.

[0029] As Figure 5 and Figure 6As shown, further: The anti - detachment mechanism 53 includes an end plate 531. The end plate 531 is divided into a blocking surface and a vertical surface, and the blocking surface and the vertical surface form an L - shape. The corner of the end plate 531 is rotatably connected to the fixed seat 5; An articulated seat 532 is provided on the outer wall of the vertical surface of the end plate 531. A second cylinder 533 is provided on the fixed seat 5. The fixed end of the second cylinder 533 is articulated to the fixed seat 5, and the output end of the second cylinder 533 is articulated to the articulated seat 532.

[0030] As Figure 7 shown, further: One end of the roller 32 close to the end plate 531 is provided with a bottom ring 7. A cage 71 is provided on the bottom ring 7, and ball bearings 72 are arranged around the cage 71.

[0031] As Figure 6 shown, further: An arc - surface groove frame 6 is provided on the fixed seat 5. The arc - surface groove frame 6 is located below the brush roller 3; An arc - surface extraction plate 61 is slidably arranged inside the arc - surface groove frame 6.

[0032] As Figure 3 shown, further: The opposite - movement control mechanism 2 includes a bottom frame 21. A limiting rod 22 and a driving rod 23 are provided on the bottom frame 21. The limiting rod 22 is fixedly connected to the bottom frame 21, and the driving rod 23 is rotatably connected to the bottom frame 21; The limiting rod 22 passes through the bases 11 of the two clamps 1 and is slidably connected thereto. Two threaded grooves are oppositely arranged on the driving rod 23, and the bases 11 of the two clamps 1 are respectively threadedly connected to the two threaded grooves; The opposite - movement control mechanism 2 further includes a third rotary driver 24 for controlling the rotation of the driving rod 23.

[0033] The third rotary driver 24 is a stepping motor, and synchronous wheels are respectively arranged on the driving rod 23 and the output shaft of the stepping motor and are connected by a synchronous belt.

[0034] In this solution, the main clamp 1 and the sub - clamp 1 are driven by the opposite - movement control mechanism 2 to move towards each other, so as to stretch the glass fiber. Specifically, the third rotary driver 24 controls the rotation of the driving rod 23. Since the bases 11 of the two clamps 1 are respectively threadedly connected to the two threaded grooves, the driving rod 23 will control the main clamp 1 and the sub - clamp 1 to move towards each other; The cleaning of the clamping surface of the clamp 1 specifically refers to the cleaning of the top clamping surface at the bottom of the clamping plate 13. When the first cylinder 14 pulls the clamping plate 13 to the upper position, the translation control mechanism 4 starts to work. The first rotary driver 44 controls the rotation of the threaded rod 43. Since the threaded rod 43 passes through the connecting frame 41 and is threadedly connected to the connecting frame 41 through a nut, the threaded rod 43 will drive the brush roller 3 to reciprocate from the bottom of the clamping plate 13 through the connecting frame 41. During the movement, the second rotary driver 52 drives the roller shaft. The roller shaft 31 drives the roller 32 to rotate with it through the cooperation of the strip withdrawal and the keyway. The outer edge surface of the roller 32 is covered with bristles to clean the resin, fiber debris or impurities on the top clamping surface of the clamping plate 13. During the cleaning process, some attachments may fall off and will be caught by the arc-shaped extraction plate 61 in the arc-shaped groove frame 6 at the bottom of the brush roller 3. The operator can clean the attachments by pulling out the arc-shaped extraction plate 61; Since the brush roller 3 cannot continue to complete the cleaning process of the top clamping surface of the clamping plate 13 after being adhered with a lot of attachments, it needs to be replaced at the right time. Specifically, the piston rod of the second cylinder 533 of the anti-detachment mechanism 53 contracts and pulls the hinge seat 532 on the vertical surface, and then the end plate 531 flips at an angle, and its blocking surface stops blocking the end of the roller 32. At this time, the operator pulls out the roller 32 and inserts a replacement; the piston rod of the second cylinder 533 extends and pushes the hinge seat 532 on the vertical surface, and then the end plate 531 flips at an angle, and its blocking surface contacts the end of the roller 32 to fix it on the roller shaft; In order to avoid the large frictional force generated by the blocking surface of the end plate 531 on the end of the roller 32 and cause damage to the roller 32 and the end plate 531, a bottom ring 7 is provided at one end of the roller 32 close to the end plate 531. A cage 71 is provided on the bottom ring 7, and ball bearings 72 are arranged around the cage 71. In this way, the rolling friction formed by the ball bearings 72 is used to replace the planar friction, forming a block for the roller 32 and ensuring its smooth rotation.
