Abstract

The application relates to the technical field of slitting devices, in particular to an automatic slitting device for high-temperature cloth processing and a clamping and slitting method thereof, which comprises a slitting machine tool and a clamping outer supporting cylinder rotatably arranged in the slitting machine tool. The high-temperature cloth roll is supported and clamped through the clamping outer supporting cylinder, and the high-temperature cloth roll is driven to rotate. A moving control assembly and a cutting driving box are further arranged in the slitting machine tool, and the moving control assembly is used for moving control of the cutting driving box.

Description

Technical Field

[0001] This invention relates to the field of slitting device technology, specifically to an automatic slitting device for high-temperature fabric processing and its clamping and slitting method. Background Technology

[0002] During the processing of high-temperature cloth, it is often necessary to roll it up and then cut it. The high-temperature cloth roll formed after rolling up the high-temperature cloth is supported by paper tubes inside and the high-temperature cloth is wound on the outside. The paper tubes provide support as the paper core layer to prevent the high-temperature cloth roll from collapsing. During the cutting process, the high-temperature cloth is cut together with the paper core layer to form a structure similar to traditional adhesive tape, so as to facilitate the application of high-temperature cloth.

[0003] High-temperature fabric is a composite material made by impregnating high-performance glass fiber cloth with polytetrafluoroethylene (PTFE). The base material of high-temperature fabric is glass fiber, which has high hardness and strong wear resistance. Therefore, the main cutting disc for cutting high-temperature fabric is usually made of tungsten steel, resulting in higher costs. Currently, there are generally two methods for slitting high-temperature fabric rolls. One method involves direct cutting by the main cutting disc, cutting the fabric roll along with the paper core layer. To ensure complete severance of the paper core layer, the main cutting disc needs to make contact with the clamping outer support cylinder. This method results in faster wear of the main cutting disc and higher processing costs. The other method involves pre-setting annular grooves on the surface of the clamping outer support cylinder. During cutting, the main cutting disc engages in these grooves, also completely cutting the fabric roll along with the paper core layer. Furthermore, the main cutting disc does not need to contact the clamping outer support cylinder, resulting in lower production costs and making this the mainstream method. However, this method has limitations. Because the annular grooves on the surface of the clamping outer support cylinder are pre-set, the cutting width can only be adjusted according to the pre-set grooves, and the cutting width cannot be adjusted at any time. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic slitting device for high-temperature fabric processing and its clamping and slitting method, so as to solve the technical problems mentioned in the background art, such as high slitting cost or inability to adjust the cutting width at any time in existing slitting devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic slitting device for high-temperature fabric processing, comprising a slitting machine tool and a clamping outer support cylinder rotatably disposed in the slitting machine tool, which supports and clamps the high-temperature fabric roll and drives the high-temperature fabric roll to rotate. The slitting machine tool is also provided with a motion control component and a cutting drive box, and the motion control component controls the movement of the cutting drive box. The cutting drive box is provided with a main cutting disc, and the cutting drive box drives the main cutting disc to rotate, cutting the high-temperature fabric roll down to the paper core layer. The slitting machine tool is also provided with a slitting cutter. After the main cutting disc completes cutting and retracts, the slitting cutter advances along the cutting path of the main cutting disc, cutting the paper core layer of the high-temperature fabric roll.

[0006] A tool slide is provided below the slitting tool, and the slitting tool is detachably and fixedly mounted on the tool slide. A support plate is fixedly provided on the outside of the cutting drive box, and a first cylinder is mounted on the support plate. A functional cylinder shaft is provided in the first cylinder. The first cylinder drives the tool slide to move through the functional cylinder shaft to complete the infeed and retraction of the slitting tool.

[0007] A support slide rail is fixedly provided on the surface of the support arm plate. The support slide rail passes through the tool slide table, so that the tool slide table can slide along the length direction of the support slide rail. An end baffle is fixedly provided at the end of the support slide rail, and the end baffle limits the movement of the tool slide table.

[0008] The tool slide has a rapid separation chamber, a blocking ring is fixedly installed in the rapid separation chamber, and a release shaft is fixedly installed at the end of the functional cylinder shaft. The release shaft passes through the blocking ring and extends into the interior of the rapid separation chamber.

[0009] The end of the release shaft is fixedly provided with a locking protrusion. The locking protrusion can only move axially inside the quick separation chamber by the limiting of the blocking ring. A separation spring is provided between the tool slide and the first cylinder. The separation spring applies elastic pressure to the tool slide, so that the tool slide has a tendency to move away from the location of the first cylinder.

[0010] The tool slide is also provided with a retaining plate groove inside, which is connected to the quick separation cavity. A locking plate is provided in the retaining plate groove, which limits the locking protrusion so that a distance is reserved between the locking protrusion and the blocking ring.

[0011] The locking plate has a return slope at its end. When the locking protrusion is pressed against the return slope, it can push the locking plate to retract along its length.

[0012] The tool slide is also provided with a dial axis moving groove inside, which is connected to the locking plate groove. A synchronous dial axis is fixedly installed on the surface of the locking plate, and the synchronous dial axis passes through the dial axis moving groove and extends to the outside of the tool slide.

[0013] A fulcrum shaft is fixedly installed on the outer surface of the tool slide. A fixed bushing is fitted around the fulcrum shaft, and the fixed bushing can rotate around the fulcrum shaft. An L-shaped vertical arm, a first arm plate, and a second arm plate are fixedly installed on the fixed bushing. A synchronous shifting groove is opened in the L-shaped vertical arm, and the synchronous shifting shaft is locked in the synchronous shifting groove. When the fixed bushing rotates, the synchronous shifting shaft and the locking plate can be moved linearly through the L-shaped vertical arm.

[0014] The surface of the slitting cutter is provided with a side wall groove, and a force-applying plate is provided in the side wall groove. The force-applying plate is fixedly installed with the first arm plate.

[0015] The tool slide is symmetrically provided with double-sided support plates on both sides of the fixed bushing. A U-shaped spring is installed on one side of the double-sided support plate, and a second cylinder is installed on the other side of the double-sided support plate. The U-shaped spring applies elastic pressure to the second arm plate, causing the force-applying plate to tend to move into the side wall groove. When the second cylinder extends, it can apply a thrust to the other side of the second arm plate, so that the second arm plate overcomes the elastic force of the U-shaped spring and drives the force-applying plate to move out of the side wall groove.

[0016] A clamping and slitting method for high-temperature fabric processing, the method employing an automatic slitting device for high-temperature fabric processing, includes the following steps:

[0017] Step 1: Place the high-temperature fabric roll onto the clamping outer support cylinder, and achieve support and clamping through the friction between the clamping outer support cylinder and the high-temperature fabric roll;

[0018] Step 2: Drive the main cutting disc to rotate through the cutting drive box, and control the movement of the cutting drive box through the movement control component, so that the main cutting disc cuts the high-temperature cloth roll to the paper core layer.

[0019] Step 3: After the main cutting disc completes the cutting, the main cutting disc is retracted by the movement control component, and then the paper core layer is cut by the slitting blade.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The automatic slitting device for high-temperature fabric processing of the present invention, through its structural design, allows the main cutting disc to first cut the high-temperature fabric roll down to the paper core layer, and then the slitting blade completely slits the paper core layer. This effectively avoids contact wear between the main cutting disc and the clamping outer support cylinder. Since the slitting blade is only used for cutting the paper core layer, it can be made of lower-cost steel and is easy to replace, significantly reducing tool cost and wear during the slitting process. Furthermore, compared to the traditional technology that uses a pre-set annular groove on the outer surface of the clamping outer support cylinder to accommodate the main cutting disc and ensure complete slitting, the automatic slitting device of the present invention can slit different spacing widths, which can be adjusted arbitrarily, making it more flexible.

[0022] 2. This invention, through the coordinated structure of the force-applying plate, the first arm plate, the locking plate, and the release shaft, can monitor the cutting status of the paper core layer during the cutting process of the slitting blade. At the instant the paper core layer is completely cut, the cut high-temperature fabric roll will move axially. Through the structural design, this invention enables the slitting blade to quickly retract a certain distance, achieving immediate separation between the slitting blade and the clamping outer support cylinder. Compared to the method of controlling the pressure change in the first cylinder through a solenoid valve and then retracting the slitting blade, the above structure can separate the slitting blade and the clamping outer support cylinder to a certain distance in a shorter time, thereby reducing the contact wear time between the slitting blade and the clamping outer support cylinder and effectively extending the service life of the slitting blade.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1 to 8 The present invention provides a technical solution: an automatic slitting device for high-temperature fabric processing, including a slitting machine tool 1 and a clamping outer support cylinder 2. The clamping outer support cylinder 2 is rotatably arranged in the slitting machine tool 1. The high-temperature fabric roll is supported and clamped by the clamping outer support cylinder 2, and the high-temperature fabric roll is driven to rotate. The clamping outer support cylinder 2 achieves support and clamping with the high-temperature fabric roll through friction. The high-temperature fabric roll is composed of an inner cylindrical paper core layer and an outer wound high-temperature fabric.

[0034] like Figure 2As shown, the slitting machine tool 1 is equipped with a transmission box 101, and two drive spindles 102 are mounted on the transmission box 101. The transmission box 101 drives the two drive spindles 102 to rotate. Specifically, the slitting machine tool 1 is internally equipped with a motor and a reduction gear set. The slitting machine tool 1 outputs rotational power to the transmission box 101, and the drive is distributed through two sets of meshing gears in the transmission box 101, so that the two drive spindles 102 are driven synchronously. The clamping outer support cylinder 2 is sleeved on the drive spindle 102. The rotation of the drive spindle 102 drives the clamping outer support cylinder 2 to rotate. The clamping outer support cylinder 2 and the drive spindle 102 are detachable, so that clamping outer support cylinders 2 of different models and diameters can be replaced to adapt to high-temperature fabric rolls with different inner diameters. One end of the drive spindle 102 is equipped with an end locking arm 103, which locks and clamps the clamping outer support cylinder 2. Specifically, as shown... Figure 2 As shown, the end locking arm 103 includes a hanging arm portion and a bolt portion. The bolt is screwed into and presses against the outer surface of the clamping outer support cylinder 2, thereby clamping and limiting the clamping outer support cylinder 2. The other end of the drive spindle 102 is provided with an opening and closing baffle 104. The opening and closing baffle 104 can be flipped. When the opening and closing baffle 104 is flipped open, it facilitates the installation and disassembly of the high-temperature cloth roll. When the opening and closing baffle 104 is flipped and contacts the end of the drive spindle 102, it can support and stabilize the drive spindle 102.

[0035] The slitting machine tool 1 is also equipped with a motion control component and a cutting drive box 3. The motion control component controls the movement of the cutting drive box 3. The motion control component is as follows: Figure 1 As shown, the machine tool includes a Y-axis moving stage 301 and an X-axis moving stage 302. The Y-axis moving stage 301 can move back and forth relative to the X-axis moving stage 302, that is, in a top-view angle, the Y-axis moving stage 301 can move along the Y-axis. The X-axis moving stage 302 can move left and right relative to the slitting machine tool 1, that is, in a top-view angle, the X-axis moving stage 302 can move along the X-axis. The internal structure of the Y-axis moving stage 301 and the X-axis moving stage 302 uses a conventional lead screw structure combined with a servo motor for control, which will not be described in detail in this application. Corrugated rubber sleeves 303 are provided on both sides of the X-axis moving stage 302. The corrugated rubber sleeves 303 protect the lead screw structure on both sides of the X-axis moving stage 302 internally, preventing processing dust from falling onto the lead screw and affecting the smoothness of movement.

[0036] The cutting drive box 3 is equipped with a main cutting disc 4. The main cutting disc 4 is driven to rotate by the cutting drive box 3 to cut the high-temperature cloth roll to the paper core layer. Two drive spindles 102 are provided, which cooperate with the two sets of main cutting discs 4 on the cutting drive box 3 to simultaneously cut two high-temperature cloth rolls. The specific structure of one of the sets is hidden and omitted in the accompanying drawings of this invention.

[0037] The slitting machine tool 1 is also equipped with a slitting cutter 5. After the main cutting disc 4 finishes cutting and retracts, the slitting cutter 5 moves along the cutting path of the main cutting disc 4 to cut the paper core layer of the high-temperature cloth roll.

[0038] A cutter slide 6 is provided below the slitting cutter 5, and the slitting cutter 5 is detachably and fixedly mounted on the cutter slide 6; for example Figure 8 As shown, the lower part of the slitting cutter 5 has at least two sets of bolt through holes 501, such as... Figure 5 As shown, a tool clamping plate 502 is integrally formed on the upper surface of the tool slide 6. The lower part of the slitting tool 5 is inserted into the tool clamping plate 502. The slitting tool 5 is clamped and fixed by bolts passing through the tool clamping plate 502 and the bolt through hole 501. When disassembling and replacing, the bolts can be loosened. A support arm plate 7 is fixedly installed on the outside of the cutting drive box 3. A first cylinder 8 is installed on the support arm plate 7. A functional cylinder shaft 9 is provided in the first cylinder 8. The first cylinder 8 drives the tool slide 6 to move through the functional cylinder shaft 9 to complete the infeed and retraction of the slitting tool 5.

[0039] A support slide rail 701 is welded and fixedly installed on the surface of the support arm plate 7. The support slide rail 701 is an I-shaped slide rail. The support slide rail 701 passes through the tool slide 6, so that the tool slide 6 can slide along the length direction of the support slide rail 701. An end baffle 702 is welded and fixedly installed at the end of the support slide rail 701. The end baffle 702 limits the tool slide 6 and prevents the tool slide 6 from slipping off the support slide rail 701.

[0040] like Figure 6 As shown, the tool slide 6 has a quick separation chamber 601, and a blocking ring 602 is fixedly installed in the quick separation chamber 601. The blocking ring 602 and the tool slide 6 are an integral structure. The end of the functional cylinder shaft 9 is integrally machined and fixedly installed with a release shaft 603. The release shaft 603 passes through the blocking ring 602 and extends into the interior of the quick separation chamber 601.

[0041] The end of the release shaft 603 is integrally machined and provided with a locking protrusion 604. The locking protrusion 604 can only move axially inside the quick separation chamber 601 by the limiting of the blocking ring 602. A separation spring 605 is provided between the tool slide 6 and the first cylinder 8. The separation spring 605 applies elastic pressure to the tool slide 6, so that the tool slide 6 has a tendency to move away from the location of the first cylinder 8.

[0042] The tool slide 6 is also provided with a retaining plate groove 606 inside. The retaining plate groove 606 is connected to the quick separation chamber 601. A locking retaining plate 607 is provided in the retaining plate groove 606. The locking plate 607 limits the locking protrusion 604, so that a distance is reserved between the locking protrusion 604 and the blocking ring 602.

[0043] The locking plate 607 has a return slope 608 at its end. When the locking protrusion 604 is pressed and engaged with the return slope 608, it can push the locking plate 607 to retract along its length.

[0044] The tool slide 6 also has a pivot moving groove 609 inside, which is connected to the cladding plate groove 606. A synchronous pivot 610 is fixedly installed on the surface of the locking cladding plate 607. The synchronous pivot 610 passes through the pivot moving groove 609 and extends to the outside of the tool slide 6.

[0045] A fulcrum shaft 611 is fixedly installed on the outer surface of the tool slide 6. A fixed bushing 612 is sleeved on the outside of the fulcrum shaft 611. The fixed bushing 612 can rotate around the fulcrum shaft 611. An L-shaped vertical arm 613, a first arm plate 614, and a second arm plate 615 are fixedly installed on the fixed bushing 612. A synchronous shifting groove 616 is opened in the L-shaped vertical arm 613. The synchronous shifting shaft 610 is locked in the synchronous shifting groove 616. When the fixed bushing 612 rotates, the synchronous shifting shaft 610 and the locking plate 607 can be moved linearly through the L-shaped vertical arm 613.

[0046] The surface of the slitting cutter 5 is provided with a side wall groove 617, and a force-applying plate 618 is provided in the side wall groove 617. The force-applying plate 618 is welded and fixedly installed to the first arm plate 614.

[0047] The tool slide 6 is symmetrically provided with double-sided support plates 619 on both sides of the fixed bushing 612. A U-shaped spring 620 is installed on one side of the double-sided support plate 619, and a second cylinder 621 is installed on the other side of the double-sided support plate 619. The U-shaped spring 620 applies elastic pressure to the second arm plate 615, so that the force plate 618 tends to move into the side wall groove 617. When the second cylinder 621 extends, it can apply a thrust to the other side of the second arm plate 615, so that the second arm plate 615 overcomes the elastic force of the U-shaped spring 620 and drives the force plate 618 to move out of the side wall groove 617.

[0048] A clamping and slitting method for high-temperature fabric processing, the method employing an automatic slitting device for high-temperature fabric processing, includes the following steps:

[0049] Step 1: Place the high-temperature fabric roll onto the clamping outer support cylinder 2, and achieve support and clamping through the friction between the clamping outer support cylinder 2 and the high-temperature fabric roll;

[0050] Step 2: Drive the main cutting disc 4 to rotate through the cutting drive box 3, and control the movement of the cutting drive box 3 through the movement control component, so that the main cutting disc 4 cuts the high-temperature cloth roll to the paper core layer.

[0051] Step 3: After the main cutting disc 4 completes the cutting, the main cutting disc 4 is retracted by the movement control component, and then the paper core layer is cut by the slitting blade 5.

[0052] During use, the high-temperature fabric roll is placed on the outside of the clamping outer support cylinder 2. The outer surface of the clamping outer support cylinder 2 and the inner diameter surface of the high-temperature fabric roll are slightly interference-fitted. With the help of friction, the clamping outer support cylinder 2 supports and clamps the high-temperature fabric roll. At this time, the rotation of the clamping outer support cylinder 2 can drive the high-temperature fabric roll to rotate.

[0053] The motion control component controls the cutting drive box 3 and the main cutting disc 4 to move to the corresponding positions. The high-temperature fabric roll is cut by the high-speed rotation of the main cutting disc 4, cutting it down to the paper core layer. Then, the motion control component controls the main cutting disc 4 to retract. Figure 3 As shown, the slitting cutter 5 and the main cutting disc 4 are on the same plane. The slitting cutter 5 can advance along the cutting path of the main cutting disc 4 by moving forward; in conjunction with the reference... Figure 4 As shown in the figure, at this time, the first cylinder 8 controls the function cylinder shaft 9 to retract, and the function cylinder shaft 9 drives the tool slide 6 to move along the support slide rail 701 toward the support arm plate 7. At this time, the slitting tool 5 is driven by the tool slide 6, and the slitting tool 5 moves along the cutting path of the main cutting disk 4, so that the slitting tool 5 cuts the paper core layer.

[0054] When the slitting blade 5 reaches the paper core layer and begins to cut it, the second cylinder 621 extends and applies a thrust to the second arm plate 615, causing the second arm plate 615 to overcome the elastic force of the U-shaped spring 620. Figure 5 At the angle shown, the second arm plate 615 and the first arm plate 614 have a clockwise rotation tendency. However, as the force plate 618 is inserted into the cutting gap of the high-temperature cloth roll along with the slitting tool 5, the gap of the high-temperature cloth roll blocks the force plate 618, preventing it from being removed from the side wall groove 617. At this time, the first arm plate 614 only has a clockwise rotation tendency and will not rotate. Simultaneously, the second arm plate 615 and the fixed bushing 612 will also not rotate.

[0055] The first cylinder 8 drives the functional cylinder shaft 9 to retract, slowly applying force so that the slitting blade 5 gradually cuts deeper into the paper core layer. At this time, as... Figure 6 As shown, the locking protrusion 604 is locked by the locking plate 607, and the retraction of the functional cylinder shaft 9 can directly drive the tool slide 6 and the slitting tool 5 to move. At the moment the paper core layer is completely cut, because the cut high-temperature fabric roll loses the connection of the paper core layer, it will move axially to the right under the thrust of the force plate 618. Once the cut high-temperature fabric roll moves axially to the right, causing the force plate 618 to move out of the side wall groove 617, the first arm plate 614 and the fixed bushing 612 will actually rotate clockwise; as... Figure 4 As shown, the fixed bushing 612 rotates clockwise, causing the L-shaped vertical arm 613 to rotate clockwise. The L-shaped vertical arm 613, through the synchronous groove 616, moves the synchronous shaft 610 to the left, as shown. Figure 6 As shown, at this time, the locking plate 607 moves to the left, unlocking the locking protrusion 604. Under the elastic thrust of the separation spring 605, the cutter slide 6 moves away from the support arm plate 7 quickly by a distance, so that the slitting cutter 5 and the clamping outer support cylinder 2 immediately separate by a distance, avoiding the slitting cutter 5 from continuous contact and wear with the clamping outer support cylinder 2 after the slitting cutter 5 completely cuts the paper core layer, thus extending the service life of the slitting cutter 5. The above structure allows the slitting cutter 5 to immediately separate from the clamping outer support cylinder 2 by a distance, and the control function cylinder shaft 9 of the first cylinder 8 extends synchronously, so that the slitting cutter 5 completely retracts.

[0056] Compared to the method where the first cylinder 8 drives the functional cylinder shaft 9 to extend, thus separating the slitting cutter 5 from the clamping outer support cylinder 2, the latter method requires a PLC response, which transmits the response to the solenoid valve. The solenoid valve then switches the pressure inside the first cylinder 8 from negative to positive, thereby pushing the functional cylinder shaft 9 to extend and separate the slitting cutter 5 from the clamping outer support cylinder 2. This method is faster and more efficient, effectively reducing unnecessary contact wear between the slitting cutter 5 and the clamping outer support cylinder 2 after the slitting cutter 5 has completely cut the paper core layer.

[0057] During reset, the tool slide 6 interferes with the end plate 702, causing the tool slide 6 to stop moving. The first cylinder 8 controls the function cylinder shaft 9 to continue extending. (Refer to...) Figure 6 As shown, the locking protrusion 604 pushes the locking plate 607 back by pressing against the return slope 608, so that the locking protrusion 604 is re-locked by the locking plate 607.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The fixed bushing is fixedly provided with an L-shaped vertical arm, a first arm plate and a second arm plate. The L-shaped vertical arm has a synchronous dialing groove, and the synchronous dialing shaft is locked in the synchronous dialing groove. When the fixed bushing rotates, the synchronous dialing shaft and the locking plate can be moved linearly by the L-shaped vertical arm.

3. The automatic slitting device for high-temperature fabric processing according to claim 2, characterized in that: The surface of the slitting cutter is provided with a side wall groove, and a force-applying plate is provided in the side wall groove. The force-applying plate is fixedly installed with the first arm plate.

4. The automatic slitting device for high-temperature fabric processing according to claim 3, characterized in that: The tool slide is symmetrically provided with double-sided support plates on both sides of the fixed bushing. A U-shaped spring is installed on one side of the double-sided support plate, and a second cylinder is installed on the other side of the double-sided support plate. The U-shaped spring applies elastic pressure to the second arm plate, causing the force-applying plate to tend to move into the side wall groove. When the second cylinder extends, it can apply a thrust to the other side of the second arm plate, so that the second arm plate overcomes the elastic force of the U-shaped spring and drives the force-applying plate to move out of the side wall groove.

5. A clamping and slitting method for high-temperature fabric processing, wherein the method employs an automatic slitting device for high-temperature fabric processing as described in any one of claims 1-4, characterized in that, Includes the following steps: Step 1: Place the high-temperature fabric roll onto the clamping outer support cylinder, and achieve support and clamping through the friction between the clamping outer support cylinder and the high-temperature fabric roll; Step 2: Drive the main cutting disc to rotate through the cutting drive box, and control the movement of the cutting drive box through the movement control component, so that the main cutting disc cuts the high-temperature cloth roll to the paper core layer. Step 3: After the main cutting disc completes the cutting, the main cutting disc is retracted by the movement control component, and then the paper core layer is cut by the slitting blade.
