Description

Technical Field

[0001] The utility model relates to the technical field of ironing equipment, in particular to a grid online ironing device. Background Art

[0002] The grid is the core component of the RO reverse osmosis membrane. It is produced through a special process using high-tech equipment. The quality of the grid determines the safety of the RO membrane. The grid is prone to unevenness during production. Like other membrane and cloth products, it requires ironing equipment for ironing.

[0003] The ironing equipment in the prior art usually sets an oil tank inside the heating roller, and then heats the oil, thereby heating the surface of the entire roller, and further ironing the membrane cloth product.

The utility model supports the non-woven fabric through a transmission roller to prevent the non-woven fabric from loosening and falling to the bottom of the device under the action of gravity, and at the same time plays a guiding role. The cooling air blows the non-woven fabric after ironing to cool it, reduce the temperature of the surface of the non-woven fabric so that it can enter the next process, and the third motor drives the discharge roller to send the non-woven fabric out of the device. The device increases the ironing area of ​​the non-woven fabric and improves efficiency.

[0005] Generally, in order to increase the contact area between the product and the heating roller and improve the ironing efficiency, the diameter of the roller is designed to be larger. In the above-mentioned utility model, the size of the oil tank matches the size of the roller, so the size of the oil tank is also larger, which has the following shortcomings: first, only a small proportion of the oil in the oil tank is in contact with the roller surface for heat conduction, and most of the oil is unused, resulting in low oil utilization, low thermal energy utilization, and serious waste of resources (when shutting down, the heat of this part of the oil may have to be released, but it needs to be fully heated when starting); second, the overall weight of the roller is increased, and during the driving and moving process, more powerful equipment is also required, which is not conducive to enterprises reducing production costs.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Reference Figure 1-8 The utility model is a grid online ironing device, comprising a frame 1 and a heating roller 2 and a traction roller 3 arranged on the frame 1. The heating roller 2 comprises a roller body 4 and a protective shell 5 away from the working end of the roller body 4. The roller body 4 comprises an outer cylinder 11 and an inner cylinder 20 coaxial with the outer cylinder 11. A gap is arranged between the inner wall of the outer cylinder 11 and the outer wall of the inner cylinder 20. Oil grooves 16 are evenly opened on the outer wall of the inner cylinder 20 along the circumferential direction, and an electric heating rod 17 is arranged inside the oil groove 16.

[0031] The oil tank 16 is filled with heat-conducting oil.

[0032] The side cross-section of the oil tank 16 is a U-shape with an open top. A gap is provided between the inner wall of the outer cylinder 11 and the outer wall of the inner cylinder 20, so that a connection port 19 is formed between the inner cylinder 20 and the outer cylinder 11. The connection port 19 is located at the top of both ends of the oil tank 16, so that all the oil tanks 16 are connected as a whole. First, it is convenient to heat the oil, and second, the inner wall of the outer cylinder 11 is only in contact with the oil, but not with the inner cylinder (the inner cylinder and the outer cylinder are both made of steel), so that the outer cylinder 11 is heated evenly.

[0033] The working end of the roller body 4 refers to the end surface in contact with the grid 6, as shown in FIG. Figure 2 As shown, there are two roller bodies 4, the working end of the lower roller body 4 is the lower right end face, and the higher roller body 4 is the upper left end face.

[0034] When in use, the grid is wound around the outer wall of the roller body 4 and fits with the roller body 4 , and the traction roller 3 pulls the grid 6 to move forward, and the grid 6 is ironed flat when in contact with the roller body 4 .

[0035] The protective shell 5 is used to block the side of the roller body 4 that contacts the grid to prevent burns and other safety accidents caused by workers' accidental touch.

[0036] A second rotating shaft 9 is disposed inside the inner cylinder 20 . The second rotating shaft 9 is connected to the inner cylinder 20 via a support frame 12 . The roller body 4 is rotatably mounted on the frame 1 via the second rotating shaft 9 .

[0037] The second rotating shaft 9 is connected to a working end of an external driving device. The driving device may be a motor, which drives the second rotating shaft 9 to rotate.

[0038] Side plates are installed at both ends of the sides of the outer cylinder and the inner cylinder, the second rotating shaft 9 passes through the side plates, and the outer cylinder 11 and the inner cylinder 20 are fixedly connected to the side plates.

[0039] A controller 13 is disposed on the second rotating shaft 9 . A plurality of adjacent electric heating rods 17 form a group, and each group of electric heating rods 17 is electrically connected to the controller 13 .

[0040] A group of electric heating rods 17 can be one or more, and all the electric heating rods 17 can be divided into multiple groups.

[0041] A threading hole 14 is processed on the second rotating shaft 9, and an electric slip ring is set between the controller 13 and the external control console, wherein the second rotating shaft 9 is connected to the rotor of the electric slip ring, and the stator of the electric slip ring is fixedly connected to the control console. After the wire passes through the threading hole 14, it is connected to the controller 13 and the terminal on the rotor of the electric slip ring to realize the rotational connection between the wires.

[0042] The advantage of building the controller 13 inside the inner tube 20 is that if the power lines of all the electric heating rods 17 are directly connected to the external control console, there will be too many connecting wires, which is not conducive to the processing of the threading holes 14 (when the hole structure size on the shaft part is too large, it is not conducive to the structural stability of the shaft). After the controller 13 is built in, the wires between the controller 13 and the electric slip ring are mainly a single power supply wire and a signal transmission wire, which is convenient for processing the threading holes 14.

[0043] A rotating shaft seat 7 is provided on the frame 1, and the second rotating shaft 9 is rotatably connected to the rotating shaft seat 7 via a bearing.

[0044] The rotating shaft seat 7 is fixedly mounted on the frame 1 , and the roller body 4 is rotatably mounted on the frame 1 via the second rotating shaft 9 .

[0045] The protective shell 5 is wrapped around one side of the roller body 4 , and a first rotating shaft 8 is provided at the end of the protective shell 5 . The first rotating shaft 8 is rotatably connected to the rotating shaft seat 7 through a bearing. A tightening bolt 10 is provided on the side wall of the rotating shaft seat 7 , and the end of the tightening bolt 10 abuts against the first rotating shaft 8 .

[0046] The axis of the tightening bolt 10 is arranged along the radial direction of the first rotating shaft 8. When the tightening bolt 10 tightens the first rotating shaft 8, the relative positions of the protective shell 5 and the roller body 4 are fixed.

[0047] When in use, the relative position of the protective shell 5 and the roller body 4 can be adjusted by tightening the bolts 10 according to the different contact positions between the grid and the roller body 4 .

[0048] The second rotating shaft 9 passes through the first rotating shaft 8 , and the second rotating shaft 9 is rotationally connected to the first rotating shaft 8 .

[0049] Bearings are installed on the inner side and the outer side of the first rotating shaft 8. The first rotating shaft 8 and the second rotating shaft 9 are coaxial and rotate relatively.

[0050] The protective shell 5 includes an outer shell 51 and a heat insulating layer 52 located inside the outer shell 51 .

[0051] The heat insulation layer 52 reduces the heat transfer from the outer tube 11 to the external environment, reduces heat loss, and further saves resources.

[0052] A heat-insulating cylinder 15 is disposed inside the inner cylinder 20 .

[0053] The heat preservation tube 15 is also a hollow cylindrical structure, which can reduce the heat loss of the inner tube 20 and protect the controller 13 to prevent the controller 13 from being exposed to a high temperature environment, thereby improving the durability of the controller 13 .

[0054] Working principle: When in use, the grid is passed through the working end of the roller body 4, and is passed through the traction roller 3 to be pulled forward by the traction roller 3.

[0055] The electric heating rod 17 is started to heat the oil, and the oil conducts heat to the outer cylinder 11. The roller body 4 rotates, and the linear speed of the outer cylinder 11 is the same as the speed of the grid 6. The grid is ironed by the outer cylinder 11.
