The following are specific specific examples to illustrate the embodiments disclosed in the present invention related to the "over cloth head device for impregnation machine and its operating method". Those skilled in the art can understand the advantages of the present invention from the content disclosed in this specification With efficacy. The present invention can be implemented or applied through other different specific embodiments. Various details in this specification can also be based on different viewpoints and applications, and various modifications and changes can be made without departing from the spirit of the present invention. In addition, the drawings of the present invention are merely schematic illustrations, not drawn according to actual sizes, and will be described first. The following embodiments will further describe related technical contents of the present invention in detail, but the disclosed contents are not intended to limit the technical scope of the present invention.

First, please refer to Figures 1 to 3. 1 to 3 are a schematic perspective view, a side schematic view and a top schematic view of a cloth passing device for an impregnation machine provided by an embodiment of the present invention. As shown in FIGS. 1 to 3, the cloth passing device D for an impregnation machine provided by an embodiment of the present invention includes a fixed bearing housing 1, a movable bearing housing 2, a cylinder group 3, and a gap adjusting member 4. The fixed bearing housing 1 is used to carry the first metering roller 10, and the movable bearing housing 2 is used to carry the second metering roller 20. It can be seen from the three-dimensional structure shown in FIG. 1 that the fixed bearing housing 1 and the movable bearing housing 2 each have two components respectively disposed on both sides of the first metering roller 10 and the second metering roller 20. In other words, the fixed bearing housing 1 has two bearing members separated from each other, which are respectively provided at both ends of the first metering roller 10, and the movable bearing housing 2 also has two bearing members separated from each other, which are respectively provided at the first Two of the two measuring rollers 20 end.

Please also refer to Figures 1 to 3. The fixed bearing seat 1 is fixed on the frame R of the impregnation machine without moving, and the movable bearing seat 2 is arranged on the slide rail S on the frame R of the impregnation machine, so that it can be driven along by the driving device X moves horizontally. The fixed bearing housing 1 and the movable bearing housing 2 are arranged along the horizontal direction X, so that there is a gap G between the first metering roller 10 and the second metering roller 20 for the cloth material to pass through. In other words, the arrangement of the fixed bearing housing 1 and the movable bearing housing 2 can make the first metering roller 10 and the second metering roller 20 juxtaposed in the horizontal direction X to produce the first metering roller 10 and the second metering roller 20 Gap between. In this way, the cloth material (including the base cloth and the rubber material dipped on it) through the impregnation tank (not shown) can pass through the gap G between the first metering roller 10 and the second metering roller 20, thereby regulating The thickness of the glue on the surface of the base fabric. In the embodiment of the present invention, the cloth material includes a base cloth, such as a glass fiber cloth, and a rubber compound on the surface of the base cloth. In addition, the cloth material passes between the first weighing roller 10 and the second weighing roller 20 along the vertical direction Y shown in FIG. 1.

As described above, the first metering roller 10 and the second metering roller 20 of the embodiment of the present invention are rotated in opposite directions during the production of the cloth material, so that the excess force can be eliminated by the clamping and squeezing forces of the two roller surfaces. The glue is removed from the surface of the base fabric. For example, referring to FIG. 2, in the production process of the cloth material, the first metering roller theory 10 rotates clockwise, and the second metering roller 20 rotates counterclockwise to adjust the surface of the base fabric The thickness of the compound.

As mentioned above, when the head of the cloth material, that is, where the two base fabrics overlap, passes between the two measuring rollers, the gap G between the two measuring rollers is also increased due to the increase in the thickness of the base fabric itself Need to be adjusted accordingly, otherwise it will cause damage to the product fabric and reduce the yield. In the prior art, in the general production process of cloth materials, gears and screw The G is adjusted by the lever, and the precision required for the gap G in the production process is about 0.003 millimeters (mm). In the prior art, when the cloth head passes between two rollers, the general operation mode is to change the rotation mode of both rollers, that is, to change the first metering roller 10 from clockwise rotation to counterclockwise rotation, and The second metering roller 20 is changed from rotating clockwise to rotating counterclockwise. In this way, the running direction of the measuring roller can be changed to follow the running direction of the cloth head (direction Y), thereby reducing the resistance of the roller to the cloth head. At this time, the thicker cloth head can pass through the gap between the two rollers. However, the operation method in the prior art will cause the thickness of the rubber material on the surface of the base cloth near the cloth head to be different from that of the other parts of the cloth material, that is, the amount of glue near the cloth head is unevenly coated, making the product there Can not be used to reduce the efficiency of production.

Different from the prior art, as shown in FIGS. 1 to 3, the cloth passing device D for the impregnation machine provided by the embodiment of the present invention further includes a specially designed cylinder group 3 and a gap adjusting member 4. In detail, the cylinder group 3 includes a first cylinder 31 connected to the fixed bearing housing 1 and a second cylinder 32 connected to the movable bearing housing 2, and the clearance adjusting member 4 is disposed between the fixed bearing housing 1 and the movable bearing housing 2 In this way, the fixed bearing seat 1 and the movable bearing seat 2 can be pushed against each other through the gap adjusting member 4. It is worth mentioning that the over cloth head device D for the impregnation machine shown in Figures 1 to 3 is not a mode in the production process. Therefore, the fixed bearing seat 1 and the movable bearing seat shown in the figure 2 does not abut against each other through the gap adjusting member 4.

Referring also to FIGS. 1 to 3, the first cylinder 31 of the cylinder group 3 is attached to the fixed bearing housing 1. Although in the embodiments shown in FIGS. 1 to 3, the first cylinder 31 is disposed on the side of the fixed bearing seat opposite to the first metering drum 10, in the present invention, the specific location of the first cylinder 31 and No restrictions. As long as the first cylinder 31 is connected to the fixed bearing housing 1 and can be directly or indirectly applied to the movable bearing housing 2 by supplying air pressure, the specifics of the first cylinder 31 The setting position and form can be modified or replaced.

In addition, similarly, the second cylinder 32 of the cylinder group 3 is attached to the movable bearing housing 2. However, unlike the first cylinder 31, the cylinder body of the second cylinder 32 is fixed on the frame R of the impregnation machine and connected to the movable bearing housing 2, so that the second cylinder 32 can exert force on the movable bearing housing 2, In turn, the second cylinder 32 is driven to reciprocate in the direction X. Similarly, as long as the second cylinder 32 can perform the above function, the specific installation position and form of the second cylinder 32 can be modified and replaced.

Specifically, one of the technical features of the present invention is that the first cylinder 31 and the second cylinder 32 in the embodiment of the present invention are used to drive the movable bearing housing 2 to move along the horizontal direction X through the gap adjusting member 4 to adjust The width of the gap G. In other words, one of the technical features of the present invention is that, through the design and adjustment of the cylinder group 3, the width of the gap G between the first metering roller 10 and the second metering roller 20 can be changed instantly. In this way, there is no need to change the rotation directions of the first metering roller 10 and the second metering roller 20, which greatly reduces the production cost. Furthermore, since the time for the change of the width of the gap G is extremely short, that is, the two metering rollers instantly return to the original production position, the amount of glue on the surface of the base cloth near the cloth head can still be kept at the same level as the rest. The amount of glue on the surface of the cloth is consistent, thereby greatly improving production efficiency.

Next, please also refer to Figure 4. FIG. 4 is a pneumatic circuit diagram of a cylinder block for a cloth passing device of an impregnation machine provided by an embodiment of the present invention. As shown in the figure, in the embodiment of the present invention, both the first cylinder 31 and the second cylinder 32 are connected to the same gas source 8. In addition, as shown in FIGS. 1 to 3, the first cylinder 31 and the second cylinder 32 have a first cylinder bore and a second cylinder bore, respectively, and the first cylinder bore is smaller than the second cylinder bore. For example, the second cylinder bore may be 125 millimeters (mm), and the first cylinder bore may be 25 millimeters (mm). Therefore, the two cylinders are connected to the same air source, and both cylinders are subject to In the case of the same air pressure driving, the driving force of the first cylinder 31 having a smaller first cylinder diameter is lower than that of the second cylinder 32 having a larger second cylinder diameter. In this way, in the production process, the fixed bearing seat 1 connected to the first cylinder 31 and the movable bearing seat 2 connected to the second cylinder 32 are pushed against each other by the gap adjusting member 4 to produce a material suitable for the passage of cloth Gap G. In fact, in the production process, the first cylinder 31 connected to the fixed bearing housing 1 cannot push the movable bearing housing 2 connected to the second cylinder 32 to the right (direction X).

Please refer to FIG. 4 again, and refer to FIG. 3 together. As mentioned above, since the two metering drums are provided with a carrier assembly at both ends (the first metering drum 10 has a fixed carrier assembly at both ends, and the second metering drum 20 has two components Each side has an assembly of movable carrier 2). Similarly, as shown in FIG. 3, the first cylinder 31 and the second cylinder 32 of the cylinder group 3 also have two correspondingly provided on the first metering drum 10 and the second The cylinder bodies at both ends of the metering drum 20 are measured. In FIG. 3, in order to maintain the simplicity of the drawing, only the elements on one side of the two metering drums are labeled. As shown in FIG. 4, the first cylinder 31 includes two cylinder bodies 311 and 312, and the second cylinder 32 includes two cylinder bodies 321 and 322.

In addition, in the gas path where the first cylinder 31 and the second cylinder 32 are connected to the gas source 8, a pressure regulating valve 7 is also provided. In addition, a solenoid valve 6 is additionally provided in the gas path where the second cylinder 32 having a larger cylinder diameter is connected to the air source. The solenoid valve 6 may be, for example, a five-port, three-position solenoid valve (wherein the middle position is a valve that quickly exhausts the cylinder). However, the present invention does not limit the types of the pressure regulating valve 7 and the solenoid valve 6. Specifically, the solenoid valve 6 is used to control the air pressure supplied to the second cylinder 32 from the gas source 8 through the air path, that is, the solenoid valve 6 is used to switch the state of supplying air to the second cylinder 32. Therefore, with the solenoid valve 6, the driving capacity of the second cylinder 32 can be adjusted. In addition, in the gas path between the second cylinder 32 and the air source 8, a speed control valve 323 and 速消声器324.

Next, please refer to FIGS. 1 to 3 again. As mentioned above, the cloth passing device D for the impregnation machine provided by the present invention further includes the gap adjusting member 4. Specifically, the gap adjuster 4 includes a cylinder joint 41 and an adjustment screw 42. The cylinder joint 41 is connected to the first cylinder 31, and the adjustment screw 42 is connected to the movable bearing housing 2. In the embodiment of the present invention, the cylinder joint 31 may be surface-hardened, and the adjusting screw 32 may be surface-hardened. In addition, the adjusting screw 42 can be fixed on the fixing base 5.

As mentioned above, in the production process of the cloth material, the cylinder joint 41 and the adjusting screw 42 are pushed against each other. In fact, in the production process of the cloth material, the cylinder group 3 is started, so that the second cylinder 32 of the cylinder group 3 drives the movable bearing housing 2 to move in the reverse direction X, thereby making the fixed bearing housing 1 and the movable bearing housing 2 Abut each other through the gap adjusting member 4. At this time, although the first cylinder 31 of the cylinder group 3 is also supplied with air pressure to apply force to the movable bearing housing 2 through the gap adjusting member 4, as described above, since the first cylinder diameter of the first cylinder 31 is smaller than the second cylinder In the second cylinder bore of 32, when both the first cylinder 31 and the second cylinder 32 receive the same air pressure supplied by the air source 8, the first cylinder 31 cannot push the second cylinder 32 in the direction X. In this state, the width of the gap G between the first metering drum 10 and the second metering drum 20 is controlled by an explosion-proof inverter motor with gears and screws.

Next, in the process of passing the cloth head, that is, when the junction of the two base cloths (called the cloth head) is about to pass through the gap G between the first metering drum 10 and the second metering drum 20, the cylinder can be switched The solenoid valve 6 in the gas line connected to the second cylinder 32 in the group 3 causes the solenoid valve 6 to be activated to the neutral position, thereby exhausting the air pressure in the second cylinder 32. This situation is similar to the situation where the second cylinder 32 is in neutral, so that the second cylinder 32 does not have the power to drive the movable bearing housing 2 at the moment when the solenoid valve 6 is activated to the neutral position. At this time, the third The first cylinder 31 can push the movable bearing housing 2 through the abutment of the gap adjusting member 4 in the X direction without the resistance provided by the second cylinder 32, so that the fixed bearing housing 1 and the movable bearing housing 2 The distance increases instantaneously, and the gap G between the first metering drum 10 and the second metering drum 20 is increased to allow a thicker cloth head to pass through. In this state, the width of the gap G between the first metering drum 10 and the second metering drum 20 is controlled by the adjusting screw 42 of the gap adjusting member 4.

In the embodiment of the present invention, in the process of passing the cloth head, the width of the gap G formed by switching the solenoid valve 6 may be the width that just passes the cloth head. Specifically, at this time, the width of the gap G is preferably in the range of 200 to 900 micrometers (μm), more preferably in the range of 400 to 850 micrometers, and most preferably in the range of 600 to 810 micrometers. In addition, the accuracy of the width can be maintained within ±3 microns.

After the cloth head passes through the gap G between the first metering drum 1 and the second metering drum 2, it is necessary to quickly switch the solenoid valve 6 to the state where the cloth production process was originally performed, so that the second cylinder 32 has sufficient air pressure again. The movable bearing housing 2 is returned to the original position in the opposite direction of the direction X, and at the same time, the gap G between the first metering drum 1 and the second metering drum 2 is returned to the original production process, which is suitable for the cloth material to pass width. At this time, the width of the gap G is preferably in the range of 100 to 450 micrometers (μm), more preferably in the range of 200 to 425 micrometers, and most preferably in the range of 300 to 405 micrometers.

Next, an embodiment of the present invention also provides an operation method for the over-cloth device of the impregnation machine. Specifically, the operation method provided by the embodiment of the present invention is described with respect to the cloth passing device D of the impregnation machine. Therefore, the following will only describe the steps of the operating method, and for the structure and the interrelationship of the components of the over-head device D of the impregnating machine that have been described previously, here will be No longer.

See Figure 5. FIG. 5 is a flowchart of an operation method of a cloth passing device for an impregnation machine provided by an embodiment of the present invention. First, in step S400, in the first state, the movable bearing housing 2 is driven by the second cylinder 32 so that the movable bearing housing 2 abuts against the fixed bearing housing 1 through the gap adjusting member 4, wherein the first metering roller There is a first gap between 10 and the second metering roller 20 for the cloth material to pass through.

As mentioned above, the first state is actually the production process of the cloth material, that is, when the base fabric coated with the rubber passes through the gap G between the first metering roller 10 and the second metering roller 20, it passes the first The procedure for removing excess glue from the measuring cylinder 10 and the second measuring cylinder 20. As mentioned earlier, in this step, the air source 8 connected to the cylinder group 3 simultaneously supplies air pressure to both the first cylinder 31 and the second cylinder 32, but since the first cylinder 31 has a smaller first cylinder diameter than the second cylinder The second cylinder bore of 32, at this time, the second cylinder 32 pushes the movable bearing housing 2 provided on the slide rail to move in the reverse direction X to press against the fixed bearing housing 1.

Next, in step S402, in the second state, the solenoid valve 6 is activated to quickly exhaust the second cylinder 32 to drive the movable bearing housing 2 through the first cylinder 31 and via the clearance adjuster 4, so that the first There is a second gap between the metering roller 10 and the second metering roller 20 for the cloth head to pass through, wherein the second gap is larger than the first gap. The width of the first gap is preferably in the range of 100 to 450 microns (μm), more preferably in the range of 200 to 425 microns, and most preferably in the range of 300 to 405 microns. The width of the second gap is preferably in the range of 200 to 900 microns (μm), more preferably in the range of 400 to 850 microns, and most preferably in the range of 600 to 810 microns.

In fact, the state described in step S402 is the state where the cloth head passes between the two measuring drums in the production process of the cloth material. As mentioned before, when the cloth head passes through two measuring rollers During the gap G between the cylinders, the second cylinder 32 can be quickly exhausted by activating the solenoid valve 6 to the neutral position. In this way, the first cylinder 31 that loses the resistance of the second cylinder 32 can push the movable bearing housing 2 (And the second metering drum 20 carried on the movable bearing housing 2), thereby widening the gap G between the two metering drums to allow the cloth head to pass smoothly. In this way, in step S402, it is not necessary to adjust or change the rotation direction of the two metering drums as in the prior art, so that the cloth head can pass without affecting the production efficiency of the cloth material product.

Finally, in step 404, the solenoid valve is closed, so that the second cylinder 32 drives the movable bearing housing 2 again to return to the first state. In fact, step 404 is to immediately exhaust the second cylinder 32 through the solenoid valve 6 and then immediately switch the solenoid valve 6 to the mode under the fabric production process. In this way, the second cylinder 32 Sufficient air pressure is momentarily supplied to drive the movable bearing housing 2 to move in the reverse direction X again, and the movable bearing housing 2 is pressed against the fixed bearing housing 1 through the gap adjusting member 4. At this time, the cloth passing device D for the impregnation machine returns to the first state, in which the gap G between the first metering drum 10 and the second metering drum 20 is just capable of passing the cloth material, and passes the gap G( It is called the first gap G) in the method flow, and the amount of glue on the surface of the base fabric can be controlled.

[Feasible efficacy of the embodiment]

In summary, the beneficial effect of the present invention is that the cloth passing device D for the impregnation machine provided by the embodiment of the present invention and the operation method thereof are designed by the cylinder group 3 and the gap adjusting member 4 to make During the production process, the cloth head can smoothly pass through the gap G between the two measuring rollers without affecting the efficiency of the cloth production and reducing the scrap rate of the product.

In detail, the first cylinder 31 and the second cylinder 32 of the cylinder group 3 cooperate with the gap adjusting member 4 to adjust the width of the gap G between the first metering drum 10 and the second metering drum 20 degree. More specifically, when the cloth head passes through the gap G, the second cylinder 32 is instantly exhausted, so that the second cylinder 32 does not have the ability to drive the movable bearing housing 2 in a very short time, and the first cylinder 31 The movable bearing housing 2 can be pushed, thereby increasing the width of the gap G. Furthermore, after the cloth head passes through the gap G, the second air cylinder 32 is quickly supplied with air pressure again, so that the overall production process of the cloth material can be continued.

In this way, through the cloth head device D for the impregnation machine provided by the embodiment of the present invention and the operation method thereof, when the cloth head passes through the gap G, there is no need to change the rotation directions of the two metering drums as in the prior art. The production cost can be greatly reduced, and since the driving state of the second cylinder 32 is switched in a very short time, the rubber material on the base cloth near the cloth head can still be accurately measured by the first metering roller 10 and the second metering roller 20 Control, thereby greatly reducing the scrap rate of cloth materials (for example, from 5 meters (m) to 1 meter), thereby improving production efficiency.

Although the embodiments of the present invention are disclosed in a more detailed manner as described above, those of ordinary skill in the art can understand that various modifications of the present invention can be made without departing from the scope of the present invention defined in the appended patent application. . Therefore, further modifications of the examples of the present invention will not deviate from the scope of the patent application of the present invention.
