Description

Technical Field

[0001] This utility model relates to the technical field of impregnation and drying production lines, specifically to a vertical impregnation and drying production line with a steering top roller chamber. Background Technology

[0002] The drying section of the resin-impregnated fiberglass cloth for copper clad laminate substrates mostly adopts a vertical drying and cooling system. The drying and cooling are divided into two parts: upward and downward. The fiberglass cloth is turned from top to bottom through the top roller chamber, and the fiberglass cloth is further cooled to promote resin curing, thereby obtaining a copper clad laminate substrate with uniform structure and consistent performance.

[0003] The organic solvents used in resin formulation are usually flammable and explosive, so the fabric-drawing roller of the steering mechanism is required to have anti-static properties. To achieve consistent performance, the fabric-drawing roller must be cooled evenly; otherwise, uneven resin curing and internal stress will occur, leading to warping, deformation, or delamination of the fiberglass cloth. The temperature of the top roller chamber is relatively high compared to room temperature, so it is necessary to prevent the fabric from sticking to the fabric-drawing roller. Overall, a fabric-drawing roller with conductivity, anti-stick properties, and uniform cooling is required to meet production needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a vertical impregnation and drying production line with a steering top roller chamber, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A vertical impregnation and drying production line includes a top roller chamber, which contains multiple rollers. Each roller includes an outer sleeve and an inner sleeve. The outer sleeve is fitted over the inner sleeve, and an anti-stick conductive coating is applied to the outer side of the outer sleeve. A guide vane is provided between the outer sleeve and the inner sleeve, forming a flow channel. Shaft heads are connected to both sides of the outer sleeve and the inner sleeve, and a flow channel hole is machined in the middle of the shaft head, communicating with the flow channel. A main inlet pipe and a main return pipe are installed in the chamber, and the rollers are connected in parallel between the main inlet pipe and the main return pipe.

[0006] Furthermore, the non-stick conductive coating is a Teflon coating, in which carbon fiber and metal conductive particles are added.

[0007] Furthermore, the guide vanes adopt a spiral structure.

[0008] Furthermore, the outer sleeve is connected to both ends with an outer sleeve sealing plate, and the inner sleeve is connected to both ends with an inner sleeve sealing plate. The end of the shaft head is welded to the inner sleeve sealing plate. A through hole is opened on the outer sleeve sealing plate, through which the shaft head passes. The periphery of the shaft head is welded and fixed to the periphery of the through hole. An inner tube hole is opened around the end of the inner sleeve, and the cooling liquid flowing out of the flow channel hole enters the guide channel through the inner tube hole.

[0009] Furthermore, the outer sleeve sealing plate is machined with a plug hole, and a plug is connected to the plug hole.

[0010] Furthermore, the roller includes a top roller and a pressure roller.

[0011] Furthermore, a left-side water inlet main pipe, a left-side water return main pipe, a right-side water inlet main pipe, and a right-side water return main pipe are respectively installed on both sides of the chamber. The roller shaft is connected to the left-side water inlet main pipe, the left-side water return main pipe, the right-side water inlet main pipe, and the right-side water return main pipe through pipes, and the water inlet and outlet directions of adjacent rollers alternate.

[0012] Compared with the prior art, the vertical impregnation and drying production line of this utility model has the following beneficial effects: 1. A special non-stick conductive coating is used, which can prevent the fiberglass cloth from sticking to the roller, and at the same time make the roller conductive, avoiding the adverse effects of static electricity; 2. The guide channels formed by the internal guide vanes guide the cooling water and carry away the heat from the roller surface; 3. The rollers inside the chamber include both top rollers and pressure rollers, so that both sides of the fiberglass cloth are cooled. 4. The rollers are connected in parallel with the inlet and outlet water mains, allowing for independent water intake and improved cooling performance; 5. The water inlet and outlet directions of adjacent rollers are changed alternately to improve cooling uniformity. Attached Figure Description

[0014] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0015] like Figure 1 and Figure 2As shown, a vertical impregnation and drying production line has a top roller chamber, including a chamber 1. Multiple rollers are installed within the chamber 1. Each roller includes an outer sleeve 2 and an inner sleeve 3. The outer sleeve 2 is fitted onto the inner sleeve 3. An anti-stick conductive coating 4 is applied to the outer side of the outer sleeve 2. In this embodiment, the anti-stick conductive coating 4 is a Teflon coating. Carbon fibers and conductive metal particles, such as copper, aluminum, or silver particles, are added to the Teflon coating. Compared to traditional hard chrome plating composite coatings, this coating retains the conductive properties of the chrome plating layer and is resistant to acids, alkalis, and organic solvents. It also exhibits good wear resistance, high temperature resistance, good anti-stick properties, and is easy to clean. This coating utilizes the wear resistance, temperature resistance, and anti-stick properties of Teflon. To achieve the conductive function of the coating, conductive fillers such as carbon fibers and metal particles are added to the Teflon. A special process strengthens the bonding force between the coating and the metal roller material, effectively preventing coating peeling, ensuring uniform conductivity distribution, and better meeting usage requirements.

[0016] A guide vane 5 is provided between the outer sleeve 2 and the inner sleeve 3, forming a guide channel 6 between the guide vane 5 and the outer sleeve 2 and the inner sleeve 3. Shaft heads 7 are connected to both sides of the outer sleeve 2 and the inner sleeve 3, and a flow channel hole 8 is machined in the middle of the shaft head 7, which communicates with the guide channel 6. In this embodiment, the guide vane 5 adopts a spiral structure. The guide vane 5 is welded to the inner cylinder 3, and the inner circle of the outer cylinder 2 is bored out. The outer cylinder 2 and the outer circle of the spiral guide vane of the inner cylinder 3 are interference-fitted. A heating kit is used to achieve the sealing of the guide channel 6 while enhancing the rigidity of the roller. In addition, the spiral guide channel is conducive to the flow of cooling water and improves the cooling effect of the roller.

[0017] The outer sleeve 2 is connected to the outer sleeve sealing plate 9 at both ends, and the inner sleeve 3 is connected to the inner sleeve sealing plate 10 at both ends. The end of the shaft head 7 is welded to the inner sleeve sealing plate 10. A through hole is opened on the outer sleeve sealing plate 9, and the shaft head 10 passes through the through hole. The periphery of the shaft head 7 is welded and fixed to the periphery of the through hole. An inner tube hole 11 is opened around the end of the inner sleeve 3. The cooling liquid flowing out of the flow channel hole 8 enters the guide channel 6 through the inner tube hole 11.

[0018] The outer sleeve sealing plate 9 is machined with a plug hole, and the plug hole is connected to a plug 12. During equipment maintenance, the plug hole drains the cooling water in the guide channel 6.

[0019] The chamber 1 is equipped with an inlet water main and an outlet water main. The rollers are connected in parallel between the inlet water main and the outlet water main, allowing the rollers to receive and exit water independently, thus improving the cooling effect.

[0020] In this embodiment, a left-side water inlet main pipe 13, a left-side water return main pipe 14, a right-side water inlet main pipe 15, and a right-side water return main pipe 16 are respectively installed on both sides of the chamber 1. The roller shaft head 7 is connected to the left-side water inlet main pipe 13, the left-side water return main pipe 14, the right-side water inlet main pipe 15, and the right-side water return main pipe 16 through a pipe 17. The end of the shaft head 7 is machined with a connecting hole 18, and the pipe 17 is connected to the connecting hole 18 through a rotary joint. Since the cooling water is at a low temperature when it enters the guide channel 6 of the roller, and at a high temperature when it flows out of the guide channel 6 due to heat exchange, the water inlet and outlet directions of adjacent rollers are alternately changed in order to ensure the uniformity of roller cooling.

[0021] like Figure 1 As shown, in this embodiment, four rollers are arranged in the chamber 1. The terminals on both sides are side top rollers 19, and the middle is arranged with pressure roller 20 and middle top roller 21 in sequence. The left side top roller 19 and middle top roller 21 are connected to the right water inlet main pipe 15 and the left return water main pipe 14. The pressure roller 20 and the left side top roller 19 are connected to the left water inlet main pipe 13 and the right return water main pipe 16. The water inlet and outlet directions of the side top roller 19, pressure roller 20 and middle top roller 21 are changed alternately to make the fiberglass cloth cool evenly. At the same time, the side top roller 19 and middle top roller 21 are in contact with the back of the fiberglass cloth, while the pressure roller 20 is in contact with the surface of the fiberglass cloth, so that the fiberglass cloth is cooled on both sides.
