Description

Technical Field

[0001] This application belongs to the technical field of desizing and firing fabric frame, specifically relating to a secondary desizing and firing fabric frame for electronic glass fiber cloth. Background Technology

[0002] A desizing and burning fabric rack is an auxiliary device used in a desizing furnace. Fabric rolls are loaded onto the desizing and burning fabric rack and placed into the desizing furnace for desizing.

[0003] Desizing and burning fabric racks typically use support arms to support fabric rolls. To prevent the fabric rolls from swaying relative to the support arms, related technologies incorporate arc-shaped grooves on the support arms. The ends of the fabric rolls can be positioned within these grooves to prevent swaying. In practical use, forklifts or other conveying equipment are typically used to place the desizing and burning fabric racks equipped with fabric rolls into the desizing furnace. However, when the conveying equipment accelerates, the fabric rolls are prone to swaying relative to the support arms and colliding with the desizing and burning fabric rack, which can obviously damage the fabric. Summary of the Invention

[0004] The purpose of this application is to provide a secondary desizing and burning frame for electronic glass fiber cloth, which can solve the problem that the cloth roll is prone to collision with the desizing and burning frame and damages the cloth when the conveying equipment is accelerating.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] This application provides a secondary desizing and burning frame for electronic glass fiber cloth, used to support the material roll. The frame includes a frame body, with a protruding support arm on the first side wall, and support arms on both sides of the frame body. Each support arm on both sides has an arc-shaped groove, which is used to position and place the two ends of the material roll.

[0007] The distance between the center of the arc-shaped groove and the first sidewall in the first direction is called the first distance, and the radius of the arc-shaped groove is equal to the first distance, wherein the first direction is the direction extending from the first sidewall to the support arm.

[0008] In this embodiment, the distance between the center of the arc-shaped groove on the support arm and the first sidewall in the first direction is the first distance. The first direction is the direction extending from the first sidewall to the support arm. The first distance is equal to the radius of the arc-shaped groove. That is, the circular outline formed along the extension direction of the arc-shaped groove is tangent to the first sidewall. Since the part of the material roll placed in the arc-shaped groove is adapted to the shape of the arc-shaped groove, the radius of the part of the material roll placed in the arc-shaped groove is equal to the radius of the arc-shaped groove. Thus, after the material roll is positioned in the arc-shaped groove, the part of the material roll placed in the arc-shaped groove will be tangent to the first sidewall, and there is no gap between the two. Therefore, during the acceleration of the forklift, the first sidewall can stop and limit the material roll, preventing the material roll from moving towards the first sidewall under the action of inertia, so as to avoid the problem of the material roll colliding with the first sidewall during the movement and damaging the material roll.

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0024] The electronic glass fiber cloth secondary desizing and burning frame provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0025] The inventors discovered that the support arm of the related technology is located on the side wall of the desizing and burning frame. After the fabric roll is placed in the arc groove on the support arm, there is a gap between the fabric roll and the side wall of the desizing and burning frame. In other words, the side wall of the desizing and burning frame does not contact the fabric roll. Therefore, during the acceleration of the forklift, the fabric roll will move towards the side wall of the desizing and burning frame under the action of inertia, causing the fabric roll to collide with the desizing and burning frame.

[0026] Please see Figures 1 to 5 This application discloses a secondary desizing and firing frame for electronic glass fiber cloth, hereinafter referred to as a desizing and firing frame for simplicity. It is used to support the material roll 400 and includes a frame body 100. A support arm 110 protrudes from the first side wall 101 of the frame body 100. That is, the support arm 110 is located on the frame body 100 and protrudes from the first side wall 101. The support arm 110 can be connected to the first side wall 101 or to other parts of the frame body 100. The components are partially connected, and the frame 100 has support arms 110 on both sides. Each support arm 110 has an arc-shaped groove 111. These grooves are used to position the two ends of the material roll 400. In other words, the shape of the end of the material roll 400 matches the shape of the arc-shaped groove 111. When a portion of the material roll 400 is positioned within the arc-shaped groove 111 in its radial direction, the outer circumferential surface of the end of the material roll 400 is in contact with the inner wall of the arc-shaped groove 111. Specifically, the material roll 400 may include a material roll shaft and fabric wound around it; or the material roll 400 may only include the material roll shaft. This application does not limit this.

[0027] The center of the arc groove 111 and the first sidewall 101 in the first direction ( Figure 2 The distance along the direction indicated by the arrow (x) is the first distance, and the radius of the arc groove 111 is equal to the first distance. The first direction is the direction extending from the first sidewall 101 to the support arm 110. Specifically, the center of the arc groove 111 is the center of the arc contour in which the arc groove 111 is located.

[0028] In this embodiment, the distance between the center of the arcuate groove 111 on the support arm 110 and the first sidewall 101 in a first direction is a first distance. The first direction is the direction extending from the first sidewall 101 towards the support arm 110. The first distance is equal to the radius of the arcuate groove 111. That is, the circular outline formed along the extension direction of the arcuate groove 111 is tangent to the first sidewall 101. Since the portion of the material roll 400 disposed in the arcuate groove 111 is adapted to the shape of the arcuate groove 111, the portion of the material roll 400 disposed in the arcuate groove 111... The radius is equal to the radius of the arc groove 111. Thus, after the material roll 400 is positioned in the arc groove 111, the part of the material roll 400 in the arc groove 111 will be tangent to the first side wall 101, and there is no gap between the two. Therefore, during the acceleration of the forklift, the first side wall 101 can stop and limit the material roll 400, preventing the material roll 400 from moving towards the first side wall 101 under the action of inertia, so as to avoid the problem of the material roll 400 colliding with the first side wall 101 during the movement and damaging the material roll 400.

[0029] When conveying equipment such as forklifts decelerates, the roll 400 on the desizing and burning frame tends to move in the first direction. Therefore, when the conveying equipment decelerates too quickly, the roll 400 may sway in the arc groove 111, which may cause the roll 400 to fall off the desizing and burning frame.

[0030] To prevent roll 400 from falling off the desizing and burning frame, please refer to... Figure 2 , Figure 4 , Figures 6 to 8 In one optional embodiment, at least one end of the material roll 400 is provided with a protrusion 410 extending along an annular contour, and at least one side of the frame 100 is provided with a locking member 200. The locking member 200 includes a locking portion 210 and is connected to the support arm 110 or the frame 100. The locking member 200 can switch between a first position and a second position. Specifically, the locking member 200 can move relative to the support arm 110 or the frame 100 to switch between the first position and the second position. Optionally, the locking member 200 can move relative to the support arm 110 or the frame 100, or the locking member 200 can rotate relative to the support arm 110 or the frame 100. This application does not limit this.

[0031] When the locking member 200 is switched to the first position, the locking part 210 can contact the bottom of the inner surface of the protrusion 410, that is, the locking part 210 is located above a part of the protrusion 410 so that the locking part 210 and the material roll 400 are in a limiting engagement in the first direction; when the locking member 200 is switched to the second position, the locking part 210 and the protrusion 410 are offset in the vertical direction, and the locking part 210 and the material roll 400 are released from the limiting engagement.

[0032] In this embodiment, when the locking member 200 is switched to the first position, the locking part 210 can contact the bottom of the inner surface of the protrusion 410, and the locking part 210 and the material roll 400 are engaged in an upper limit cooperation in the first direction. In this way, the locking part 210 can stop and limit the material roll 400, preventing the material roll 400 from moving in the first direction, thereby preventing the material roll 400 from falling off the desizing and burning frame. When it is necessary to remove the material roll 400 from the support arm 110, the locking member 200 can be switched to the second position. At this time, the locking part 210 and the protrusion 410 are offset in the vertical direction. That is to say, the locking part 210 is no longer located above a part of the protrusion 410 and is not in contact with the material roll 400. In this way, the material roll 400 can be lifted upward, making it easier to remove the material roll 400 from the support arm 110.

[0033] Furthermore, when the locking member 200 is switched to the first position, the locking part 210 engages with the material roll 400 in the vertically upward direction. That is, the locking part 210 can stop and limit the material roll 400 to prevent it from moving upward. In this embodiment, the locking part 210 engages with the material roll 400 in the vertically upward direction. When the material roll 400 has a tendency to move along the first direction, the portion of the protrusion 410 located below the locking part 210 will abut against the locking part 210. At this time, the force exerted by the locking part 210 on the protrusion 410 extends downward, thus the limiting effect of the locking part 210 on the material roll 400 is even better. Furthermore, when the locking member 200 is switched to the first position, the locking part 210 and the material roll 400 are engaged in an axial upper limit engagement, so that the locking part 210 can prevent the material roll 400 from moving axially, making the material roll 400 more stably placed in the arc groove 111.

[0034] Please see Figure 6In an optional embodiment, the protrusion 410 can be positioned in the arc groove 111, and the locking part 210 is made of an elastic material, that is, the locking part 210 is elastic. When the locking member 200 is switched to the first position, the bottom surface of the locking part 210 is in contact with the inner surface of the protrusion 410 so that the locking part 210 and the material roll 400 are in a vertically upward upper limit engagement. In this embodiment, the protrusion 410 can be positioned in the arc-shaped groove 111. When the locking member 200 is switched to the first position, the bottom surface of the locking member 210 is in contact with the inner surface of the protrusion 410. That is, the protrusion 410 is clamped between the locking member 200 and the inner wall of the arc-shaped groove 111. Thus, when the roll 400 tends to move in the first direction, the protrusion 410 of the roll 400 will squeeze the locking member 210, causing the locking member 210 to undergo longitudinal elastic deformation. This allows the locking member 210 to exert greater resistance on the protrusion 410, thereby making the roll 400 more stably positioned in the arc-shaped groove 111. Of course, the protrusion 410 can also be located in the arc-shaped groove 111, and the protrusion 410 can also be made of a rigid material. This application does not limit this.

[0035] Please see Figures 7 to 8 In an optional embodiment, the locking member 200 further includes a pressure-receiving portion 220 connected to the locking portion 210. The material roll 400 can press the pressure-receiving portion 220 to switch the locking member 200 from the second position to the first position. Optionally, the pressure-receiving portion 220 has a pressure-receiving surface 221, and the material roll 400 can press the pressure-receiving surface 221. The pressure-receiving surface 221 can be an inclined surface, an arc surface, etc. Of course, if the pressure-receiving portion 220 does not have a pressure-receiving surface 221, a pressing surface can be provided on the material roll 400. The pressing surface can be an inclined surface or a plane. Optionally, the material roll 400 is provided with a pressing portion 420, which can press the pressure-receiving portion 220. The pressing portion 420 can be an annular protrusion.

[0036] The specific working process is as follows: Before the material roll 400 is placed into the arc-shaped groove 111, the locking member 200 is in the second position. During the process of placing the material roll 400 into the arc-shaped groove 111, the material roll 400 presses the pressure portion 220 of the locking member 200, thereby switching the locking member 200 to the first position, thus realizing the state switching of the locking member 200. It can be seen that with the structure of this embodiment, the state switching of the locking member 200 can be completed during the placement of the material roll 400. This not only eliminates the need for manual operation or the use of other driving components to switch the locking member 200 from the second position to the first position, but also eliminates the need to determine whether the material roll 400 is placed in the arc-shaped groove 111 before switching the locking member 200 to the second position, thus simplifying the control logic of the desizing and burning fabric frame. Of course, in addition to using the material roll 400 to switch the locking member 200 from the second position to the first position in this embodiment, manual operation or the use of other driving components can also be used to switch the locking member 200 from the second position to the first position.

[0037] In an optional embodiment, the pressure-bearing part 220 is an elastic arm, the first end of which is fixedly connected to the support arm 110. The locking member 200 can rotate around the first end of the elastic arm and can rotate from the second position to the first position. When the material roll 400 moves upward from the arc groove 111, the protrusion 410 can squeeze the locking part 210 to make the elastic arm bend and deform, and to switch the locking member 200 to the first position. In this embodiment, the pressure-bearing part 220 is an elastic arm. The first end of the elastic arm is fixedly connected to the support arm 110. The elastic arm itself is elastic, so it can rotate around its first end. During the process of the material roll 400 being placed into the arc groove 111, the material roll 400 can press the elastic arm to switch the locking member 200 to the first position. When it is necessary to remove the material roll 400 from the desizing and burning frame, the material roll 400 can be lifted upwards directly using the lifting equipment so that the protrusion 410 contacts the locking member 210. The lifting equipment further lifts the material roll 400. Since the lifting equipment applies a large force to the material roll 400, the protrusion 410 will squeeze the locking member 210, thereby applying an outward force to the locking member 210. This can force the elastic arm to bend and deform so that the elastic arm is disengaged from the material roll 400, thereby switching the locking member 200 to the first position.

[0038] Of course, the pressure-bearing part 220 can also be rotatably connected to the support arm 110 via a rotating shaft; the pressure-bearing part 220 can also be a rigid structural component. In this case, the end of the pressure-bearing part 220 away from the support arm 110 can include multiple sub-parts connected in series and hinged. A torsion spring is provided on the rotating shaft between two adjacent sub-parts. When the material roll 400 moves upward from the arc groove 111, the two adjacent sub-parts will rotate relative to each other, thereby causing the elastic arm to disengage from the material roll 400.

[0039] To prevent the locking element 200 from being switched to the second position when it is in the first position, please refer to Figure 4 , Figure 6 In one optional embodiment, at least one side of the frame 100 is provided with a stop mechanism 300. The stop mechanism 300 is connected to the support arm 110 or the frame 100. The stop mechanism 300 includes a stop member 310. The stop mechanism 300 can switch between a third position and a fourth position. That is, the stop mechanism 300 can move relative to the support arm 110 or the frame 100 to realize the switching of the stop mechanism 300 between the third position and the fourth position. The movement here can be rotation or movement.

[0040] When the stop mechanism 300 is switched to the third position, the stop member 310 contacts the first end of the elastic arm, and the stop member 310 and the elastic arm are in a limited engagement in the direction in which the locking member 200 rotates from the first position to the second position; when the stop mechanism 300 is switched to the fourth position, the stop member 310 and the elastic arm are separated, and the limited engagement between the stop member 310 and the elastic arm is released. In this embodiment, when the locking member 200 is in the first position, the stop mechanism 300 can be switched to the third position. At this time, the stop member 310 is located outside the elastic arm and is in contact with the first end of the elastic arm. Thus, the stop member 310 can stop and limit the elastic arm, preventing the locking member 200 from rotating from the first position to the second position. In this way, the locking member 200 can stably limit the material roll 400 to prevent the material roll 400 from falling off the desizing and burning frame when the conveying equipment decelerates. Before it is necessary to remove the material roll 400 from the desizing and burning frame, the stop mechanism 300 can be switched to the fourth position to release the stop member 310 from the elastic arm. Then, the locking member 200 can be switched to the second position, and finally the material roll 400 can be removed from the desizing and burning frame.

[0041] Please see Figures 9 to 11 In one optional embodiment, the bottom of the frame 100 is provided with a fork hole 120 for a forklift to insert into. The stop mechanism 300 further includes a trigger 320 and a drive 330. The trigger 320 is disposed in the fork hole 120 and is connected to the drive 330. The drive 330 is connected to the stop 310, and the forklift can press the trigger 320. Specifically, the forklift can press the trigger 320 when the fork arm extends into the fork hole 120.

[0042] When the forklift presses the trigger 320, the trigger 320 triggers the drive 330, which in turn drives the stop 310 to move, so that the stop mechanism 300 switches to the third position; when the forklift releases the trigger 320, the trigger 320 stops triggering the drive 330, and the drive 330 drives the stop 310 to reset, so that the stop mechanism 300 switches to the fourth position.

[0043] The specific working process is as follows: When it is necessary to send the desizing and burning fabric frame into the desizing furnace, the fork arm of the fork can be extended into the fork hole 120 to scoop up the desizing and burning fabric frame. During this process, the fork will press the trigger 320, which will trigger the drive 330, so that the drive 330 drives the stop 310 to move and the stop mechanism 300 switches to the third position. When the fork arm of the fork is withdrawn from the fork hole 120, the fork will release the trigger 320, which will stop triggering the drive 330, so that the drive 330 drives the stop 310 to reset and the stop mechanism 300 switches to the fourth position. As can be seen, with the structure of this embodiment, the state switching of the stop mechanism 300 can be completed during the forklifting and unloading of the desizing and burning fabric frame. This eliminates the need to confirm whether the stop mechanism 300 has switched to the third position before the forklift operates, and also eliminates the need to confirm whether the stop mechanism 300 has switched to the fourth position before removing the fabric roll 400, thus simplifying the control logic of the desizing and burning fabric frame. Of course, in addition to this embodiment, the stop mechanism 300 can also be switched between the third and fourth positions manually.

[0044] Please see Figure 11 In an optional embodiment, the trigger 320 is a wedge-shaped block, which is slidably connected to the fork hole 120 in the vertical direction. The drive 330 includes a first link 331 and a second link 332. The first link 331 is rotatably mounted on the frame 100, with its first end located below the wedge-shaped block. The second end of the first link 331 is connected to the second link 332, which extends vertically. A stop 310 is located on the second link 332. When the trigger 320 is pressed, the wedge-shaped block presses down on the first link 331, and the second link 332 drives the stop 310 to move upward, thereby switching the stop mechanism 300 to a third position. Specifically, the top surface of the wedge-shaped block is an inclined plane, and the distance between the inclined plane and the ground gradually increases in the direction in which the forklift extends into the fork hole 120. Optionally, with Figure 11 Taking the perspective shown as an example, the first link 331 and the second link 332 can be fixedly connected. When the first link 331 rotates, the second link 332 will move upward and shift to the left by a certain distance. Therefore, this embodiment needs to reserve space for the second link 332 to shift to the left; or the first link 331 and the second link 332 can be slidably connected in the horizontal direction to compensate for the distance that the second link 332 slides to the left during the rotation of the first link 331.

[0045] The specific working process is as follows: During the process of the forklift's fork arm extending into the fork hole 120, the forklift will press the wedge block to make the wedge block slide downward. During the downward sliding process, the wedge block will press the first end of the first link 331, causing the first end of the first link 331 to move downward. Since the first link 331 is rotatably mounted on the frame 100, the downward movement of the first end of the first link 331 will drive the first link 331 to rotate around its rotation axis. At this time, the second end of the second link 332 will move upward, thereby driving the stop 310 mounted on the second link 332 to move upward. At this time, the stop mechanism 300 can switch to the third position. During the process of the forklift's fork arm exiting the fork hole 120, the forklift will release the wedge block. The second link 332 will move downward under its own weight. In this way, the second link 332 will drive the first link 331 to rotate, causing the first end of the first link 331 to lift upward, thereby resetting the wedge block. As can be seen, in this embodiment, the stop 310 can be moved by the mechanical connection between the wedge block, the first connecting rod 331 and the second connecting rod 332, so that no additional drive source is needed, thereby saving energy consumption of the desizing and burning fabric frame.

[0046] Optionally, the stop mechanism 300 also includes an elastic element 340, the two ends of which are connected to the wedge block and the base 130 respectively. The elastic element 340 can drive the wedge block to reset so that the stop mechanism 300 can quickly switch from the third position to the fourth position.

[0047] Optionally, the trigger 320 can also be a trigger button, and the drive component 330 can be a telescopic component. The trigger 320 is electrically connected to the telescopic component. When the forklift presses the trigger button, the telescopic component extends / retracts; when the forklift releases the trigger button, the telescopic component retracts / extends. The telescopic component can be a cylinder, a motor-driven screw and nut mechanism, a linkage mechanism, etc.

[0048] Please see Figure 2 , Figure 6 In one optional embodiment, the frame 100 includes a base 130 and a column 140 connected to each other. Columns 140 are provided on both sides of the frame 100. Fork holes 120 are provided in the base 130. A first connecting rod 331 is rotatably provided in the base 130. A second connecting rod 332 is slidably provided in the column 140. An avoidance notch 141 is provided on the column 140. One end of a stop member 310 passes through the avoidance notch 141 and is connected to the second connecting rod 332. When the stop mechanism 300 is switched to the fourth position, the stop member 310 and the inner wall of the avoidance notch 141 are engaged in a vertically downward direction.

[0049] In this embodiment, the second link 332 is slidably disposed within the column 140, thus the column 140 can guide the second link 332 to ensure stable movement. Furthermore, one end of the stop member 310 passes through the clearance notch 141 and connects to the second link 332, thus the clearance notch 141 can also guide the stop member 310, allowing stable movement of the stop member 310 and the second link 332 connected to it. In addition, when the stop mechanism 300 is switched to the fourth position, the stop member 310 engages with the inner wall of the clearance notch 141 in a vertically downward direction. That is, the inner wall of the clearance notch 141 can stop and limit the stop member 310 to prevent it from moving further downward. This ensures that the stop mechanism 300 is accurately positioned in the fourth position, and that the first link 331, the second link 332, and the trigger member 320 are in preset positions. Of course, the second link 332 can also be located outside the column 140, and this application does not restrict this.

[0050] Optionally, the first end of the elastic arm is provided with a groove 222. When the stop mechanism 300 is in the third position, at least a portion of the stop member 310 is located within the groove 222, and the stop member 310 is in upper limit engagement with the inner wall of the groove 222 in the vertically upward direction. In this embodiment, the first end of the elastic arm is provided with a groove 222, which reduces the thickness of the first end of the elastic arm, making it easier for the elastic arm to deform. When the stop mechanism 300 is in the third position, the stop member 310 is in upper limit engagement with the inner wall of the groove 222 in the vertically upward direction. That is, the elastic arm can stop and limit the stop member 310 to prevent the stop member 310 from continuing to move upward. This prevents the stop member 310 from moving upward too much, thereby ensuring that the stop mechanism 300 is accurately located in the third position.

[0051] Please see Figure 12 In one optional embodiment, the two side arms 110 form a set of support components. At least two sets of support components are provided, spaced apart vertically. The arms 110 of each set of support components above the lowest support component are rotatably mounted on the frame 100. The axis of rotation between the arms 110 and the frame 100 extends vertically. Optionally, the axis of rotation between the arms 110 and the frame 100 can be located inside the first sidewall 101, i.e., the axis of rotation and the first sidewall 101 are sequentially arranged along a first direction. In this case, a clearance opening needs to be provided on the frame 100. After the arms 110 of each support component rotate in a direction away from each other, the arms 110 of each support component are located within the clearance opening. Alternatively, the axis of rotation between the arms 110 and the frame 100 can be located outside the first sidewall 101, i.e., the first sidewall 101 and the axis of rotation are sequentially arranged along a first direction.

[0052] In this embodiment, the support arms 110 of each support component located above the lowest support component are rotatably mounted on the frame 100, so that the support arms 110 of each support component rotate in a direction away from each other. In this way, the support arms 110 of each support component can avoid the material roll 400 below, thereby facilitating the removal of the material roll 400 below. This reduces the gap between two adjacent support components and increases the number of support components.

[0053] Please see Figure 3 , Figure 5 And / or, in an optional embodiment, the arc-shaped groove 111 is used to position the roller body of the material roll 400, on which fabric is wound. In this embodiment, the roller body is located within the arc-shaped groove 111. Because the cross-sectional area of ​​the roller is large, the radius of the arc-shaped groove 111 is also large, which increases the contact area between the material roll 400 and the arc-shaped groove 111, thereby reducing the pressure generated between the material roll 400 and the arc-shaped groove 111 and preventing damage to the material roll 400. Of course, in addition to the roller body of the material roll, the arc-shaped groove 111 can also be used to position other parts of the material roll.

[0054] The foregoing embodiments of this application focus on describing the differences between various embodiments. As long as the different optimization features between embodiments are not contradictory, they can be combined to form better embodiments. For the sake of brevity, these differences will not be elaborated upon here. The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art, under the guidance of this application, can make many modifications without departing from the spirit and scope of the claims, all of which fall within the protection scope of this application.
