Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane pultrusion molding, in particular to a non-stop pad assembly for a pultrusion production line. Background Art

[0002] The pultrusion process is a method for continuously producing composite profiles. It is an automated production process in which glass fibers and other continuous reinforcing materials on a yarn rack pass through a forming die with a certain cross-sectional shape and are continuously discharged from the die after being cured in the die.

[0003] In polyurethane pultrusion molding, the glass fibers are clamped and pulled by the opposite tracks of a caterpillar machine. Since the time for the glass fibers to be cured into profiles is about 50 - 90 seconds; therefore, at the initial stage of starting the machine, the caterpillar machine needs to clamp and drag the bundle of glass fibers, and it takes about 50 - 90 seconds to have formed profiles. During this process, there is a large height difference between the height at which the caterpillar machine clamps the bundle of glass fibers and the height at which it clamps the cured profiles. In the prior art, when switching between the two, the caterpillar machine needs to be stopped, and then the clamping height of the caterpillar machine is manually increased to ensure that the clamping height adapts to the cured profiles. However, the above method is prone to phenomena such as dead mold and fault shutdown. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a non-stop pad assembly for a pultrusion production line, which can gradually increase the clamping height of the caterpillar machine, so as to avoid stopping the machine to adjust the clamping height of the caterpillar machine and prevent phenomena such as dead mold and fault shutdown.

[0029] The following further describes the present invention in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only parts related to the present invention are shown in the drawings, rather than all the structures.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] As Figures 1 to 6 shown, the present utility model provides a pultrusion production line non-stop pad assembly, which is applied to a crawler machine and can adjust the clamping height between the upper and lower crawlers 8 of the crawler machine without stopping the machine. The pultrusion production line non-stop pad assembly includes a plurality of first pads 1 and at least one second pad 2. Each first pad 1 has a relative first upper end face and a first lower end face. The first upper end face is an inclined plane inclined in the first direction. When a plurality of first pads 1 are spliced in sequence in the first direction, a plurality of first upper end faces can be spliced to form an inclined plane, and the height of the inclined plane gradually increases in the first direction; each first lower end face is provided with a first groove 11 along the first direction to be able to bind the glass fiber 6; the second pad 2 has a relative second upper end face and a second lower end face. The second upper end face is a plane, and the height of the second upper end face is the same as the height of the highest point of the inclined plane. The second pad 2 can be spliced to the first pad 1 in the first direction, and a second groove 21 is provided on the lower end face of the second lower end face to be able to bind the glass fiber 6.

[0034] When the crawler machine clamps the glass fiber 6 for pultrusion, the operator can insert the above-mentioned first pad 1 between the upper and lower tracks 8 of the crawler machine in sequence, so as to form an inclined plane with gradually increasing height by using the first pads 1 spliced ​​in sequence, and gradually adjust the height of the crawler machine; when the height adjustment is completed, a number of second pads 2 are inserted in sequence to keep the height between the upper and lower tracks 8 of the crawler machine at the height of the second pad 2 until the glass fiber 6 is solidified to form a complete profile 7, so that the profile 7 can smoothly enter between the upper and lower tracks 8 for clamping, so that the height between the upper and lower tracks 8 can be adjusted without stopping the machine, avoiding the occurrence of dead mold, fault shutdown and the like.

[0035] In the current embodiment, the first direction refers to the length direction of the first cushion block 1, which is also Figure 1 and Figure 2 The X direction in .

[0036] It can be understood that the number of first pads 1 and the number of second pads 2 are generally multiple, and the specific number can be set according to the usage situation. The splicing of multiple first pads 1 gradually increases the distance between the upper and lower tracks 8 of the crawler machine, and the second pads 2 can maintain the distance between the two tracks 8. Based on this, the highest height of the last first pad 1 and the height of the second pad 2 to be formed can be kept consistent with the profile 7, so that the profile 7 can be smoothly clamped between the tracks 8.

[0037] In some embodiments, when adding the first pad 1 between the two crawlers 8, in order to avoid the instantaneous excessive increase in the distance between the two crawlers 8, the height difference between the two ends of each first pad 1 in the first direction is 10mm, so that the distance between the two crawlers 8 is gradually increased, the crawlers 8 are kept stable, and the shutdown jam is avoided. It should be noted that the length of the first pad 1 and the length of the second pad 2 are not specifically limited; illustratively, in order to facilitate the insertion of the first pad 1 and the second pad 2 into the crawler machine, the length of the first pad 1 and the length of the second pad 2 are both 800mm.

[0038] like Figures 2 to 3As shown, in some embodiments, the first groove 11 runs through both ends of the first cushion block 1 in the first direction, and the second groove 21 runs through both ends of the second cushion block 2, so that the fiberglass 6 can be constrained within the first groove 11 and the second groove 21, maintaining the stability of the constraint and preventing it from disengaging from the first groove 11 and the second groove 21. At the same time, it also prevents the fiberglass 6 from being placed between the first cushion block 1 and the crawler 8 or between the second cushion block 2 and the crawler 8, avoiding affecting the pitch adjustment of the crawler 8. Further, when the second cushion block 2 is spliced to the first cushion block 1, the first groove 11 and the second groove 21 are coaxial in the first direction, so that the fiberglass 6 can be prevented from changing direction during the constraint, further ensuring the stability of the constraint and also ensuring the stability of the pulling. In addition, an anti-slip layer can be provided in the first groove 11 and the second groove 21, so that the fiberglass 6 contacts the anti-slip layer, thereby further improving the stability of the constraint. Exemplarily, the anti-slip layer can be, but is not limited to, anti-slip sheets provided in the first groove 11 and the second groove 21.

[0039] As Figure 4 shown, in some embodiments, adjacent first cushion blocks 1, between the first cushion block 1 and the second cushion block 2, or adjacent second cushion blocks 2 can all adopt abutting contact. It can be understood that, in some other embodiments, the first cushion block 1 is provided with a plug-in groove 3 at one end in the first direction and the second cushion block 2 is provided with a plug-in groove 3 at one end in the first direction, and the first cushion block 1 is provided with a plug-in protrusion 4 at the other end in the first direction and the second cushion block 2 is provided with a plug-in protrusion 4 at the other end in the first direction, so that through the above plug-in groove 3 and plug-in protrusion 4, it can be ensured that the first groove 11 and the second groove 21 are coaxial in the first direction after installation; and the above plug-in groove 3 and plug-in protrusion 4 can quickly identify the direction of the first cushion block 1 to avoid installation errors.

[0040] As Figure 1 、 Figure 5 and Figure 6 shown, in some embodiments, the pultrusion production line non-stop cushion block assembly further includes a third cushion block 5. The third cushion block 5 and the first cushion block 1 are respectively located on both sides of the second cushion block 2 in the first direction. The third cushion block 5 has a third upper surface, and the height of the third upper surface is the same as the height of the second upper surface. Since after the fiberglass 6 is cured into the profile 7, the initially cured part of the profile 7 has a poor hardness, in order to prevent the crawler 8 from directly crushing it, a third cushion block 5 can be added behind the second cushion block 2 and padded to the side of the profile 7, so that the crawler machine jointly presses the profile 7 and the third cushion block 5 to prevent the profile 7 from being directly crushed.

[0041] It should be noted here that the number of the third cushion blocks 5 can be adjusted according to the specific curing situation of the profile 7, and the length of the third cushion block 5 is not specifically limited. In the current embodiment, the length of the third cushion block 5 is 800 mm.

[0042] Further, when the third cushion block 5 is placed on the side of the profile 7, in order to avoid the protrusion of the third cushion block 5, in some embodiments, the width of the third cushion block 5 is smaller than the width of the second cushion block 2.

[0043] As Figure 1 and Figure 6 shown, in some embodiments, in order to adapt to the profile 7 in the prior art having a protrusion 71 as Figure 7 shown, and to maintain the stability of the third cushion block 5, the third cushion block 5 has a third lower end face opposite to the third upper end face. The third lower end face is provided with a third groove 51 along the first direction. The third groove 51 penetrates through both ends of the third cushion block 5 along the first direction, so that the protrusion 71 of the profile 7 can be embedded into the third groove 51, that is, the third cushion block 5 can press against part of the profile 7 to ensure their relative stability. Further, in order to ensure the height of the third cushion block 5, the end face of one side wall of the third groove 51 and the end face of the other side wall are not in the same plane, that is, there is a height difference between the end face of one side wall of the third groove 51 and the end face of the other side wall, and this height difference is equal to the thickness of the part of the profile 7 pressed by the side wall of the third groove 51, so that the height of the third cushion block 5 is the same as the height of the profile 7 to ensure the stability of the pressing. Further, the edge of the side wall of the third groove 51 pressed on the profile 7 is chamfered to reduce the damage to the profile 7.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
