[0046] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0047] As Figure 1 and Figure 2As shown, the composite material pultrusion product traceable marking device 200 of the embodiment of the present application comprises a printing roller 1 and an ink storage box 2. The printing roller 1 is adapted to be connected with the pultrusion unit 100. The pultrusion unit 100 is used to pull the composite material into a composite material pultrusion product 3. The composite material pultrusion product 3 has a printing surface 31 facing the outer circumferential surface of the printing roller 1. The outer circumferential surface of the printing roller 1 can be in rolling contact with the printing surface 31. When the composite material pultrusion product 3 moves along its conveying direction, the printing roller 1 rotates relative to the composite material pultrusion product 3 under the action of friction therebetween. The outer circumferential surface of the printing roller 1 is provided with an imprint 11. The ink storage box 2 has a first accommodating cavity 21 for accommodating ink. The first accommodating cavity 21 is connected with the printing roller 1 to guide the ink to the imprint 11, so that the imprint 11 can print a mark on the printing surface 31.

[0048] According to the composite material pultrusion product traceable marking device 200 of the embodiment of the present application, the printing roller 1 is connected with the pultrusion unit 100. When the pultrusion unit 100 pulls the composite material into the composite material pultrusion product 3, the printing surface 31 of the moving composite material pultrusion product 3 drives the printing roller 1 to roll under the action of friction, so that the printing roller 1 can cooperate with the ink in the ink storage box 2 without external power driving, and continuous printing of the mark on the printing surface 31 is realized. The printing roller 1 can roll with the movement of the composite material pultrusion product 3, which simplifies the overall structure of the marking device 200 and saves costs. The printed mark is easy to be distinguished by manual or mark recognition equipment, which improves the recognition efficiency and reduces the risk of recognition error. Compared with the related art, the present application can print the mark on the composite material pultrusion product 3, effectively reduces the labor cost, the risk of wrong barcode label sticking and recognition error, and improves the recognition efficiency.

[0049] Specifically, the printing roller 1 can be arranged on the conveying path of the composite material pultrusion product 3, such as being mounted on the pultrusion unit 100 or being arranged close to the pultrusion unit 100. The imprint 11 can be formed on the outer circumferential surface (or the surface) of the printing roller 1, that is, it can be recessed on the surface of the printing roller 1. Of course, the imprint 11 can also protrude from the outer circumferential surface of the printing roller 1, which can be determined according to actual needs. The imprint 11 can cover the entire surface of the printing roller 1 to realize continuous printing on the printing surface 31 of the composite material pultrusion product 3, which is beneficial to the later traceable marking. Alternatively, the imprint 11 can be arranged locally on the surface of the printing roller 1. Compared with the related art of spraying barcodes or manually sticking barcode labels, the imprint 11 is easier to operate and more convenient to identify. In addition, the printed mark is more intuitive than the barcode. If it is necessary to be more convenient to identify, the covering area of the printed mark on the surface of the composite material pultrusion product 3 can be designed to be larger than that of the barcode.

[0050] It should be noted that the "pulling machine set 100" can adopt the existing technology in the art, generally including a pulling machine body and a pulling die, the pulling machine body can receive and heat the composite material, and the pulling die is used to pull the heated composite material into a product.

[0051] As shown in Figure 1 and Figure 2 In some embodiments, the printing roller 1 is at least one, and the printing surface 31 is at least one, and the at least one printing roller 1 corresponds to the at least one printing surface 31 one by one.

[0052] It can be understood that according to actual needs, one or more wall surfaces of the composite material pultruded product 3 can be selected to print marks, that is, the composite material pultruded product 3 has one or more printing surfaces 31, and correspondingly, one printing roller 1 is configured for each printing surface 31, so that different materials of the composite material pultruded product 3 can be distinguished by the different positions of the printing surface 31 or the different number of the printing surface 31, further improving the visual direct distinguishability of different products.

[0053] For example, the cross section of the composite material pultruded product 3 is rectangular, at this time the composite material pultruded product 3 has four wall surfaces, and one or more wall surfaces of the composite material pultruded product 3 can be selected to set the printing roller 1, so as to print marks on the corresponding wall surface.

[0054] As shown in Figure 1 and Figure 2 In some embodiments, the printing roller 1 is a flexible printing roller 1, such as a photosensitive resin printing roller 1, and the use of the flexible printing roller 1 can reduce the pressure loss of the printing surface 31 to a certain extent when rolling in contact, while improving the adhesion to the printing surface 31, and ensuring the printing quality of the traceability mark.

[0055] As shown in Figure 1 and Figure 2 In some embodiments, the printing roller 1 is detachably connected with the ink storage box 2.

[0056] It can be understood that the printing roller 1 is designed to be detachable and replaceable, and the printing roller 1 with the corresponding printing pattern 11 can be selected according to the type of traceability mark required to be printed on different composite material pultruded products 3, so as to realize the printing of the corresponding traceability mark, and the two are detachably connected, so that only the corresponding one can be replaced when one of them is damaged, so as to ensure the service life of the mark device 200 and reduce the cost.

[0057] In addition, the printing roller 1 is designed to be rotatably connected with the pultrusion unit 100 in the pultruded composite product production system 10 described below, and is designed to be detachably connected with the pultrusion unit 100 for the convenience of replacing the printing roller 1 matched with the pultruded composite product 3 produced by the pultrusion unit 100.

[0058] As shown in Figure 1 and Figure 2 In some embodiments, the marking device 200 further comprises a box 4 having a second accommodating cavity 41 with an open bottom, and the box 4 is adapted to be connected with the pultrusion unit 100, and the printing roller 1 is rotatably connected with the second accommodating cavity 41 and at least partially located outside the open bottom of the second accommodating cavity 41.

[0059] The ink storage box 2 is arranged in the second accommodating cavity 41, and the side of the ink storage box 2 facing the printing roller 1 is in rolling contact with the outer circumferential surface of the printing roller 1, and the side of the ink storage box 2 facing the printing roller 1 is provided with an ink outlet 22 communicating with the first accommodating cavity 21 to guide the ink to the outer circumferential surface of the printing roller 1.

[0060] It can be understood that the ink storage box 2 is hidden in the box 4 by using the above structure design, wherein the ink in the ink storage box 2 can flow out from the ink outlet 22 and penetrate to the outer circumferential surface (i.e. the surface) of the printing roller 1, so that the printing mark 11 is printed on the printing surface 31 of the pultruded composite product 3 when the printing roller 1 rotates with the movement of the pultruded composite product 3.

[0061] Specifically, the extension direction of the ink outlet 22 can be consistent with the axial direction of the printing roller 1, and the length of the ink outlet 22 matches the length of the printing roller 1 to ensure the ink immersion efficiency of the entire surface of the printing roller 1; or the ink outlet 22 can have multiple ink outlets arranged in an array on the side of the ink storage box 2 facing the printing roller 1 to achieve uniform ink immersion of the entire surface of the printing roller 1. The ink storage box 2 can be located above or beside the printing roller 1 in the second accommodating cavity 41.

[0062] In combination with the above structure, the box 4 can be supported on the pultrusion unit 100 by the support 5, or the box 4 can be supported beside the pultrusion unit 100 by the support 5, which can be determined according to the production site layout space, the specifications of the pultruded composite product 3 produced, and the like, and will not be described here.

[0063] As shown in Figure 1 and Figure 2As shown, in some embodiments, the ink reservoir 2 is located above the printing roller 1, and the marking device 200 also includes a siphon tube 6 and an ink transition member 7. The first end of the siphon tube 6 is connected to the first receiving cavity 21 and is located below the plane where the ink liquid surface is located in the first receiving cavity 21 in the vertical direction. The second end of the siphon tube 6 is connected to the ink transition member 7. The ink transition member 7 rolls in contact with the outer peripheral surface of the printing roller 1 to guide the ink to the outer peripheral surface of the printing roller 1.

[0064] The ink transition component 7 is one of the brush head and the roller.

[0065] It is understandable that by adopting the above structural design, the ink storage box 2 can be placed on the outside of the printing roller 1. The ink in the ink storage box 2 can be used to contact the printing roller 1 through the brush head or the roller using the siphon principle, and the ink can be absorbed onto the surface of the printing roller 1. In this way, as the printing roller 1 rotates, the ink can be printed onto the surface of the composite material pultruded product 3 (i.e., the printing surface 31).

[0066] Specifically, in conjunction with the above structure, the ink storage box 2 can be installed on the outside of the housing 4, or the ink storage box 2 can be installed on the pultrusion unit 100 and located above the printing roller 1 to ensure the smooth implementation of the siphon scheme.

[0067] like Figure 1 As shown, in some embodiments, the imprint 11 is at least one of patterns, text, numbers and symbols. In other words, the imprint 11 can be patterns, text, numbers or symbols, or any combination of the above. The specific pattern of the imprint 11 can be set according to the type of composite pultruded product 3 (that is, the specific material used in composite pultruded product 3, the mixing ratio of different materials, etc.).

[0068] like Figure 1 As shown, in some embodiments, the ink is a water-soluble ink. The color of the ink can also be set according to the traceability mark to be printed on the pultruded product 3 of different composite materials. That is, the ink cartridge 2 can also be replaced or filled with ink of different colors according to the pultruded product 3 of different composite materials.

[0069] Understandably, in the final washing stage of the composite pultruded product 3, since water-soluble ink can be dissolved in water, the traceability mark can be washed away along with the stains, dust and residue on the surface of the composite pultruded product 3 during the washing stage.

[0070] Therefore, compared with related technologies, the present invention has the following advantages:

[0071] 1) Compared to the methods of spraying barcodes or manually affixing barcode labels, using printed markings effectively reduces labor costs and the risk of misapplying barcode labels.

[0072] 2) The entire surface of the composite pultruded product 3 can be marked with different colors, patterns or their combination for traceability. Compared with the bar code in the related art, the printed mark in the present application is large in size and obvious, and can be directly and quickly distinguished, so it is very easy for workers or mark recognition equipment to identify, improving the identification efficiency and reducing the risk of identification error;

[0073] 3) In the washing stage of the last process of the composite pultruded product 3, the mark can be directly washed away without adding additional process, effectively reducing the cost.

[0074] As shown in Figure 3 , a composite pultruded product production system 10 of an embodiment of the present application includes a pultrusion unit 100 and a marking device 200. The pultrusion unit 100 is provided with a discharge port for outputting a composite pultruded product 3. The marking device 200 is the marking device 200 of any of the above embodiments. The marking device 200 is arranged adjacent to the discharge port. The printing roller 1 of the marking device 200 is rotatably connected to the pultrusion unit 100.

[0076] As shown in Figure 3 , in some embodiments, the production system 10 further includes a mark recognition unit 300 and a washing unit 400. The pultrusion unit 100, the mark recognition unit 300 and the washing unit 400 are sequentially connected. The mark recognition unit 300 is used to identify the mark of the composite pultruded product to determine the type of the composite pultruded product. The washing unit 400 is used to wash the composite pultruded product to remove stains, dust, residues and marks on the surface of the composite pultruded product. The mark recognition unit 300 can use manual identification or mark recognition equipment identification, which has high flexibility.

[0077] As shown in Figure 3 , in some embodiments, the mark recognition unit 300 includes a vision component. The vision component is used to collect image information of the mark of the composite pultruded product. The vision component can be a camera, for example. The use of the vision component can improve the automation level of the production system 10 and further ensure the traceability efficiency.

[0078] As shown in Figure 4As shown, the composite material pultrusion product traceable marking method of the embodiment of the present application is based on the marking device 200 of any of the above embodiments, and the marking method comprises the following steps:
