Technical Field

[0001] The present invention relates to the field of pultrusion molding, and particularly to a pultrusion molding system. Background Art

[0002] The pultrusion process refers to a process method in which continuous fibers impregnated with resin or their fabrics are cured by heating through a forming die under the action of a traction device to produce composite profiles.

[0003] As mentioned above, the traction device is one of the key components of the pultrusion process. In the prior art solutions, a crawler traction device is adopted. The crawler is driven by a driving member and longitudinally moves under the action of a guide post to relatively approach and press the product output from the mold.

[0004] In the prior art pultrusion molding system, some design structures are unreasonable, resulting in difficult operation during installation and use, and increasing the costs of later operation and maintenance.

[0005] Mainly including but not limited to the following problems:

[0006] 1. It is impossible to perform linkage control on the raw material mixer and other components of the whole line to match the raw material injection speed with the product production speed, which easily leads to too much or too little injected raw material.

[0007] 2. The product cooling relies on natural cooling or air cooling, reducing the cooling efficiency per unit length and lengthening the length of the entire production line.

[0008] 3. The structure of the existing crawler traction machine is cumbersome to operate during installation and maintenance, and the later maintenance cost is relatively high.

[0009] 4. The existing core mold and yarn guiding structure are not reliably fixed, which is not conducive to quick adjustment and replacement.

[0010] Therefore, there is a need in the art for a new pultrusion molding system to solve one or a combination of the above problems. Summary of the Invention

[0015] In one or more embodiments of the pultrusion forming system, the crawler assembly further includes a lubricating brush, the lubricating brush contacts the chain, and lubricating oil can be automatically conveyed to the lubricating brush through a lubricating oil pump and a pipeline.

[0016] In one or more embodiments of the pultrusion forming system, the rolling body is a roller bearing structure, and there is a backing plate between the rolling body and the raceway; the driving member includes a cylinder, and the cylinder is installed on the frame.

[0017] In one or more embodiments of the pultrusion forming system, it further includes a platform, the platform supports and installs the die part, the yarn guiding part includes multiple rods extending transversely, one transverse end of the multiple rods is fixed to the platform, and the other end is fixed to a yarn guiding plate trolley, and a yarn guiding plate fixing member and a core mold fixing member jointly supported by the multiple rods are sequentially arranged on the multiple rods from the other transverse end to one end.

[0018] In one or more embodiments of the pultrusion system, the multiple rods are round rods, one lateral end of the multiple rods is fixedly connected to the platform via a first longitudinally extending fixed rod, and a second obliquely extending fixed rod is provided between the lateral position of the core mold fixing piece and the one lateral end and is fixedly connected to the platform.

[0019] In one or more embodiments of the pultrusion system, the yarn guide plate fixing member and the core mold fixing member are fixed to the plurality of rods via clamping blocks.

[0020] In one or more embodiments of the pultrusion system, the cooling section includes a liquid storage container, a cooling box and a liquid pump. The cooling box defines a cooling working space. The cooling box has a plurality of spray heads distributed laterally for spraying liquid onto the surface of a product located in the cooling working space for cooling. The cooling box also includes a brush downstream of the plurality of spray heads for cleaning the surface of the product sprayed with liquid.

[0021] In one or more embodiments of the pultrusion molding system, the raw material can be injected into the mold part through the feed part at a feeding speed, and the crawler traction part pulls the product at a traction speed. The molding system has a control unit, and the traction speed is input into the control unit as an input signal. After calculation and processing by the control unit, the feed speed is output from the control unit to the feed part as an output signal.

[0022] The progressive effects of this case include but are not limited to one or a combination of the following:

[0023] 1. By adopting the setting of rolling bodies and raceways, the guide column structure used in the prior art is replaced, so that the cost is reduced; on this basis, the pad is adopted, so that the overall installation and processing requirements of the traction part are greatly reduced, and the subsequent disassembly and maintenance costs are also reduced.

[0024] 2. By setting up the track plate with an inner plate, an outer plate and a locking piece, the outer plate of the track plate can be quickly replaced without replacing the inner plate, saving the time of disassembling and assembling the track plate when debugging the equipment, and avoiding the need to remove each bolt when replacing the track plate using the existing technology before the track plate can be removed from the traction chain, which is not conducive to the need to quickly replace the clamping track plate during product development.

[0025] 3. A lubricating oil pump is used to deliver lubricating oil to the lubricating oil brush to achieve automatic lubrication, ensuring the matching of the lubricating oil amount and the traction speed, avoiding the shortcomings of manual addition of lubricating oil in the prior art, which leads to excessive lubricating oil causing product contamination or insufficient lubrication and the inability of the crawler to run smoothly.

[0026] 4. The cooling system that adopts direct spray water cooling can not only clean the products, but also improve the cooling efficiency per unit length compared with the prior art that relies on natural cooling or air cooling, and shorten the length of the entire production line.

[0027] 5. The device that uses multiple rods to support and install the core mold separates the entire core mold fixing device from the mold, avoiding the cantilever deflection caused by being fixed to the mold. The separate fixing method makes the fixing more reliable and facilitates the rapid replacement of the mold.

[0028] 6. By adopting a control unit, the feeding speed of the feeding part is matched with the product production speed, ensuring that the glue injection volume can be matched with the product production speed in real time. When the production speed slows down, the glue injection volume is reduced to prevent excessive raw materials and glue leakage; when the production speed speeds up, the glue injection volume is increased to prevent insufficient raw material injection, resulting in product defects.

[0038] The following discloses various different implementation manners or embodiments for implementing the described subject technical solutions. To simplify the disclosure content, specific examples of each component and arrangement are described below. Of course, these are only examples and do not limit the protection scope of the present invention.

[0039] In addition, it should be understood that terms such as "one embodiment", "an embodiment", and / or "some embodiments", "one or more embodiments" mean a certain feature, structure, or characteristic related to at least one embodiment of the present application. Therefore, it should be emphasized and noted that the "one embodiment" or "an embodiment" or "some embodiments" or "one or more embodiments" mentioned twice or more at different positions in this specification do not necessarily refer to the same embodiment. In addition, certain features, structures, or characteristics in one or more embodiments of the present application can be appropriately combined.

[0040] As Figure 1 and Figure 2 shown, the pultrusion forming system 100 may include a feeding part 1, a yarn guiding part 2, a mold 3, a cooling part 4, a track traction part 5, and a cutting part 6. The specific installation positions may be that the mold 3 and the cooling part 4 are fixedly installed on the platform 10, and the platform 10 is fixed to the ground, while the frames of the track traction part 5 and the cutting part 6 can be directly installed on the ground. During the pultrusion forming process, the structure of the feeding part 1 may include a first feeding member 11 and a second feeding member 12, which are respectively filled with raw material A and raw material B, and are mixed in a certain proportion by a pump and then injected into the mold 3. Fabrics, such as fiberglass yarn spools, are placed on the yarn rack 8. The fabric enters the mold 3 through the yarn guiding part 2, and then is combined with raw material A and raw material B through heating and cured to form a product. After the product comes out of the mold, it is cooled by the cooling part 4 and then enters the track traction part 5. The track traction part 5 provides traction force to traction the product at a certain traction speed. The continuous product produced is cut by the cutting part 6. The specific structure of the cutting part 6 may be a cutting saw. After being cut according to the set length, it is collected on the aggregate table 7 and then packed and transported away. It can be understood that the pultrusion forming system is not limited to the content introduced as Figure 1 and Figure 2 shown. For example, the number of feeding members of the feeding part 1 is not limited to two shown in the figure, and can be more or only one.

[0041] Referring to Figures 3 to 6 in some embodiments, the track traction part 5 may include a frame 51, an upper track assembly 52, a lower track assembly 53, a driving member 54, and a moving mechanism 55. The moving mechanism 55 includes rolling elements 551 and raceways 552. The driving member 54 may be a cylinder, for example Figure 3As shown, four cylinders are installed on the frame 51 and are respectively connected to the transverse two ends of the upper track assembly 52. The lower track assembly 53 is fixed to the frame by bolts. Driven by the driving member 54 and guided by the moving mechanism 55, the upper track assembly 52 and the lower track assembly 53 can move relatively closer longitudinally to press the product. As Figure 4 As shown, the rolling element 551 of the moving mechanism 55 is a roller bearing structure and is arranged on the upper track assembly 52. The raceway 552 is fixed to the frame 51. The specific structure of the raceway 552 can be the plate-like structure shown in the figure and is detachably fixed to the frame 51. The rolling of the rolling element 551 on the raceway 552 guides the upper track assembly 52 to move downward longitudinally, so that the upper track assembly 52 approaches the lower track assembly 53 to press the product. It can be understood that the moving mechanism adopting the rolling element-raceway structure is not limited to the structure shown in the figure. For example, the upper track assembly 52 and the lower track assembly 53 can both have moving mechanisms, and the driving member can also be connected to the upper track assembly 52 and the lower track assembly 53. The structure of the moving mechanism 55 can also be that the rolling element 551 is located on the frame, while the raceway 552 is located on the upper track assembly 52 and / or the lower track assembly 53. The rolling moving mechanism has lower cost and is easier to maintain and replace compared with the guide post structure adopted in the prior art. Further, in some embodiments, a backing plate can be arranged between the rolling element 551 and the raceway 552, and the gap between the rolling element 551 and the raceway 552 can be adjusted by adjusting the thickness of the backing plate. In this way, the overall installation and processing requirements of the track assembly are greatly reduced, and the later maintenance and disassembly costs are also reduced. The principle of achieving beneficial effects by using the rolling element-raceway is that in the prior art, the guide post structure is adopted. To ensure the smooth movement of the whole, higher processing precision requirements are needed for the installation holes of the guide posts and the corresponding bushing holes. At the same time, since the guide posts need to bear a large traction force, for example, the traction force provided by the upper track assembly 52 of some pultrusion forming systems is 2.5 tons or 5 tons (the traction force provided by the whole track traction part 5 is 5 tons or 10 tons), and the guide posts need to bear the reaction force of the traction force provided by the upper track assembly 52. Therefore, the whole guide post structure requires 4 large-diameter guide posts, and processing 4 groups of guide post mating holes further increases the processing difficulty and precision. Moreover, 4 larger-diameter guide posts also require a large cost. And once the guide posts are damaged due to certain reasons, the whole track traction part 5 needs to be disassembled and assembled to replace the guide posts, and the workload of the whole disassembly and assembly is very large. For the moving structure of the rolling element-raceway, the gap requirement between the rolling element and the track is not particularly high, and the corresponding gap can be adjusted by adding gaskets with different thicknesses during assembly. Since the rolling element is installed on the outside, when maintaining, the maintenance personnel only need to operate outside to remove the rolling element and replace it with a new one, without disassembling and assembling the whole track traction part, which is very convenient compared with the guide post structure.

[0042] Continue to refer to Figures 4 to 6 , in one or more embodiments, taking the above crawler assembly 52 as an example, the crawler assembly may further include a chain 521 and crawler shoes 522. The crawler shoes 522 are fixed to the outside of the chain 521. The crawler shoes 522 include an inner plate 5221, an outer plate 5222, and a locking member 5223. The inner plate 5221 is used for fixedly connecting with the chain 521, and the outer plate 5222 is detachably connected to the inner plate 5221 through the locking member 5223. As Figure 5 shown, the sprocket 523 drives the chain 521 to rotate, and the motor 524 drives the sprocket 523 to rotate. The beneficial effect of such a setting is that the outer plate 5222 of the crawler shoe can be quickly replaced without replacing the inner plate 5221, without the need to remove and reinstall the entire crawler shoe 522, saving the time for disassembling and installing the crawler shoe 522 when debugging the equipment, and avoiding the disadvantage that each bolt needs to be disassembled when replacing the crawler shoe in the prior art solution to remove the crawler shoe from the traction chain, which is not conducive to quickly replacing the clamping crawler shoe during product development.

[0043] Refer to Figure 6 , in some embodiments, the specific structure of the crawler shoe 522 may also be that the inner plate 5221 has a convex portion, the outer plate 5222 has a concave portion, and they are connected by the cooperation of the concave portion and the convex portion. For example Figure 6 the dovetail groove connection structure in, but not limited thereto. It may also be that the inner plate 5221 has a concave portion, the locking member 5223 includes a spring 5224, a pin 5225, and a support 5226, and the outer plate 5222 has a positioning hole. When the outer plate 5222 needs to be fixedly installed on the inner plate 5221, the outer plate 5222 moves to the installation position, and the pin 5225 is nailed into the positioning hole under the action of the spring 5224 to lock the outer plate 5222 to this installation position, so that the inner plate 5221 and the outer plate 5222 are fixed. This makes the disassembly, installation, and replacement of the crawler shoe 522 more convenient, making the equipment easy to debug and maintain. In addition, the track for guiding the operation of the chain 521 can be a detachable track plate 525 for easy replacement during maintenance.

[0044] Refer to Figure 3 and Figure 5 , in some embodiments, the crawler assembly further includes a lubricating brush 56, which is fixed in the inner space of the chain 521. The lubricating brush 56 contacts the chain 521, and lubricating oil is automatically conveyed from the lubricating oil pump and pipeline to the lubricating brush to achieve automatic lubrication of the chain. As Figure 3As shown, the lubricating oil pump 57 can be installed separately on the frame 51 and is separately applicable to the lubrication of the crawler assembly. However, this is not limiting. For example, the entire pultrusion forming system 100 can share a lubricating oil pump, and the flow rate at different lubrication positions can be adjusted through the valves in the pipeline. The beneficial effect of such a setting is to achieve automatic lubrication, ensure the matching of the lubricating oil volume and the traction speed, and avoid the disadvantages in the prior art where manual addition of lubricating oil leads to excessive lubricating oil volume causing product contamination or insufficient lubricating oil volume resulting in insufficient lubrication and unstable operation of the crawler.

[0045] Reference Figure 1 、 Figure 2 And Figure 7 As shown, in some embodiments, the specific structure of the yarn guiding part 2 can include multiple rods 22, 22 extending horizontally. The specific number can be two as shown in the figure, or more. One horizontal end of each rod 22 is fixed to the platform 10, and the other end is fixed to the yarn guiding plate trolley 21. From the other horizontal end to one end of the rod 22, a yarn guiding plate fixing member 25 and a core mold fixing member 26 supported by the multiple rods 22, 22 are sequentially arranged. The beneficial effects are as Figure 1 And Figure 2 As shown, separating the fixing device for fixing the core mold 9 from the mold 3 avoids the cantilever deflection caused by being fixed to the mold 3. Adopting a separate fixing method makes the fixing more reliable and also facilitates the quick replacement of the mold 3 to meet the requirement of processing pultruded parts with multiple structures within a short time. Continuing to refer to Figure 7 , the shape of each rod 22 can be a round rod. One horizontal end of it is fixedly connected to the platform 10 through a first fixing rod 24 extending longitudinally, and a second fixing rod 23 extending obliquely is arranged and fixedly connected to the platform 10 between the horizontal position of the core mold fixing member 26 and the horizontal end. This can make the rod 22 have better rigidity and provide stable support. As Figure 7 As shown, the yarn guiding plate fixing member 25 and the core mold fixing member 26 can be clamped and fixed to the rod 22 by an upper and lower clamping structure, which is convenient for adjusting the positions of the core mold 9 and the yarn guiding plate and for disassembly and assembly. Moreover, the yarn guiding plate fixing member 25 and the core mold fixing member 26 also act as a connection of the multiple rods 22, 22 in the vertical direction perpendicular to the horizontal direction, strengthening the fixation of the multiple rods 22, 22.

[0046] Reference Figure 1 、 Figure 2 And Figure 8 、 Figure 9, in one or more embodiments, like the mold 3, the cooling unit 4 is also fixed to the platform 10. The specific structure of the cooling unit 4 includes a liquid storage container 41, a cooling box 42, and a liquid pump 43. A cooling operation space S is defined within the cooling box 42. Cooling water is drawn out from the liquid storage container 41 by the liquid pump 43 through a pipeline 441 and is conveyed to the cooling box 42 through a pipeline 442. The cooling box 42 has a plurality of spray heads 421, 421, 421 distributed horizontally, for example Figure 8 and Figure 9 as shown, three spray heads distributed horizontally in sequence, spraying the liquid onto the surface of the product located inside the cooling operation space S for 360° all-round spraying to accelerate cooling. Downstream of the spray heads 421, 421, 421, the cooling box 42 further includes a roller brush 422. The number of roller brushes 422 can be four, two longitudinally and two vertically, for cleaning the surface of the product sprayed with liquid, and the relative position can be adjusted by rotating the handle 423 to adapt to products of different specifications. The beneficial effect of such a setting is that the direct spray water-cooling cooling system can not only clean the product, but also improve the cooling efficiency per unit length compared with the prior art where product cooling relies on natural cooling or air cooling, shorten the length of the entire production line, and save the space of the production site occupied by the pultrusion forming system 100. In addition, the water in the liquid storage container 41 can be heat-exchanged with an external chiller through a cooling pipeline to ensure that the water temperature does not exceed the required temperature, ensuring that the temperature of the product at the outlet meets the requirements.

[0047] Refer to Figure 1 , Figure 2 and Figure 10 , the pultrusion forming system 100 has a control unit 200 to control the feeding speed of the raw material injected from the feeding unit 1 into the mold 3. Specifically, the traction speed of the product traction by the crawler traction unit 5 can be used as an input signal to input into the control unit 200. After calculation and processing by the control unit 200, a suitable feeding speed is obtained and output to the feeding unit 1. In this way, the feeding speed of the feeding unit can be matched with the product production speed, ensuring that the amount of injected glue can be matched with the product production speed in real time. When the production speed slows down, the amount of injected glue is reduced to prevent excessive raw materials and glue leakage; when the production speed speeds up, the amount of injected glue is increased to prevent insufficient raw material injection, resulting in product defects. In addition, the rotation speed of the above-mentioned roller brush 422 can also be controlled to match the product production speed, so that the product can be properly cooled and cleaned. As for the traction speed, it can be input through an input panel, such as an industrial control screen integrated in the frame 51 of the crawler traction unit 5, or input through a data cable connection, or wireless transmission methods such as Bluetooth, WIFI, 5G, etc.

[0048] In summary, the beneficial effects of the pultrusion forming system introduced in the above embodiments include but are not limited to:

[0049] 1. By adopting the setting of rolling elements and raceways to replace the structure of guide posts in the prior art, the cost is reduced; on this basis, a backing plate is adopted, which greatly reduces the overall installation and machining requirements of the traction part, and also reduces the later disassembly and maintenance costs.

[0050] 2. By setting the track shoe with an inner plate, an outer plate and a locking member, the outer plate of the track shoe can be quickly replaced without replacing the inner plate, saving the time for disassembling and assembling the track shoe when debugging the equipment, and avoiding the disadvantage that when replacing the track shoe in the prior art, each bolt needs to be disassembled to remove the track shoe from the traction chain, which is not conducive to the quick replacement of the clamping track shoe during product development.

[0051] 3. The lubricating oil pump is used to deliver lubricating oil to the lubricating brush to achieve automatic lubrication, ensuring the matching of the lubricating oil quantity and the traction speed, and avoiding the disadvantages in the prior art of manually adding lubricating oil, resulting in excessive lubricating oil quantity causing product contamination or insufficient lubricating oil quantity causing insufficient lubrication and the track unable to run smoothly.

[0052] 4. The direct spray water-cooling system is adopted, which can not only clean the product, but also improve the cooling efficiency per unit length compared with the prior art relying on natural cooling or air cooling, shortening the length of the entire production line.

[0053] 5. The device for supporting and installing the core mold with multiple rods is adopted, so that the entire core mold fixing device is separated from the mold, avoiding the cantilever deflection caused by being fixed to the mold. The separate fixing method makes the fixing more reliable and is convenient for the quick replacement of the mold.

[0054] 6. By adopting a control unit, the feeding speed of the feeding part is matched with the product production speed, ensuring that the glue injection amount can be matched with the product production speed in real time. When the production speed slows down, the glue injection amount is reduced to prevent excessive raw materials and glue leakage; when the production speed speeds up, the glue injection amount is increased to prevent insufficient injection of raw materials, resulting in product defects.
