Description

Technical Field

[0001] This invention relates to the field of fabric machinery technology, specifically to a long-distance fabric spreading machine for bidirectional multi-layer fabric spreading. Background Technology

[0002] In the fabric spreading process, the fabric spreading machine can transform rolls of material into multi-layered flat surfaces, thereby avoiding wrinkles and facilitating cutting.

[0003] Currently used fabric spreading machines typically extend the length of the fabric bed when spreading fabric over long distances, allowing the machine to travel as far as possible on the bed and thus complete the long-distance spreading.

[0004] However, this method of fabric spreading takes up a lot of factory space, which can easily lead to space waste in actual use. Summary of the Invention

[0005] The purpose of this invention is to provide a long-distance fabric spreading machine for bidirectional multi-layer fabric laying, so as to solve the technical problem in the prior art that long-distance fabric spreading machines occupy too much factory space.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A long-distance fabric spreading machine for bidirectional multi-layer fabric laying includes a fabric bed and a fabric spreading machine slidably disposed on the fabric bed, characterized in that...

[0008] On the fabric bed, on both sides of the fabric spreading machine, there are fabric holding points and setting points respectively. The fabric holding points are used to fix the material head on the fabric output side of the fabric spreading machine. The setting points are adjustable points set by the user. The fabric spreading machine slides back and forth between the fabric holding points as the starting point and the setting points as the ending point, and uses the two as turning points to spread the fabric.

[0009] The fabric spreading machine is provided with a pressing component on the fabric output side. The pressing component is located on both sides of the fabric. The pressing component moves with the fabric spreading machine. When the fabric spreading machine reaches a turning point, the pressing component is lowered to fix the fabric at this turning point. The fabric contacts the fixed pressing component and slides in the reverse direction of the fabric spreading machine to complete the reverse fabric laying.

[0010] Among them, the bottom layer of fabric that is in direct contact with the fabric bed is fixed to the fabric bed by the pressing component, which fixes both ends of the fabric.

[0011] The layers of fabric above the bottom layer are clamped and fixed layer by layer by the pressing components.

[0012] The pressing component includes a locking part and a rolling part. The pressing component is connected to the fabric bed and adjacent pressing components through the locking part. The pressing component is pulled out from between adjacent fabrics through the rolling part.

[0013] The rolling part includes a ball bearing and a driving mechanism. The driving mechanism is used to drive the ball bearing to contact the fabric outside the pressing member and to press the fabric outside the pressing member against the fabric bed or adjacent pressing members. The ball bearing rolls on the fabric bed or adjacent pressing members to pull the pressing member out from between the fabrics.

[0014] The pressing component is a single-piece deflector plate, and the ball bearings are disposed inside the single-piece deflector plate. The ball bearings move and protrude from the upper and lower surfaces of the single-piece deflector plate under the drive of the driving mechanism, so as to press the fabric against the fabric bed or the adjacent single-piece deflector plate.

[0015] The balls on adjacent deflector segments are staggered, and the balls roll in contact with the areas on the adjacent deflector segments where no balls are present.

[0016] As a preferred embodiment of the present invention, one side of the plurality of individual steering segments is connected by a connecting member, which can drive the plurality of individual steering segments to move synchronously to one side so as to be extracted at the same time.

[0017] As a preferred embodiment of the present invention, the single steering segment includes two split steering segments whose ends are movably connected. The opposite ends of the two split steering segments are connected in series with the ends of the other split steering segments on the same side through a connecting member. The connecting member pulls all the split steering segments on both sides to move opposite to each other so as to simultaneously pull out the split steering segments from both sides.

[0018] As a preferred embodiment of the present invention, the fabric feeding machine is further provided with a launching device on the fabric output side. The launching device is connected to the pressing component and is used to lower the pressing component onto the fabric bed or an adjacent pressing component.

[0019] The launching device connects multiple pressing components in series to form a longitudinal stack, with gaps between adjacent pressing components. The launching device drives multiple pressing components to move down synchronously, and the pressing components are placed down in sequence to replace the previous ones.

[0020] The distance by which the launching device drives the pressing component to move downward each time is equal to the sum of the gap between adjacent pressing components and the thickness of the pressing component itself.

[0021] As a preferred embodiment of the present invention, the launching device includes a fixed cylinder, the outer wall of the fixed cylinder is provided with a plurality of snap-fit ​​positions, there is a gap between adjacent snap-fit ​​positions, each snap-fit ​​position is movably snapped with the single-unit deflector piece, and each single-unit deflector piece can be adapted and connected to the snap-fit ​​position below it.

[0022] The fixed cylinder is connected to a lowering structure, which drives the single redirecting piece to disengage from its original locking position and connect with the locking position below it and the fabric bed / single redirecting piece.

[0023] As a preferred embodiment of the present invention, the lowering structure includes a movable rod, a figure-eight one-way switch and a reciprocating elastic component. The movable rod is sleeved inside the fixed cylinder and connected to the reciprocating elastic component. The reciprocating elastic component drives the movable rod to reciprocate along the length direction of the fixed cylinder.

[0024] The small end of the figure-eight one-way switch is fixedly connected to the outer wall of the movable rod, while the large end is positioned downwards and can move towards each other to narrow the opening.

[0025] The fixed cylinder is provided with a longitudinal long slot, and the figure-eight one-way switch is disposed in the longitudinal long slot.

[0026] Specifically,

[0027] When the reciprocating elastic component drives the movable rod and the figure-eight one-way switch to move upward, the large end of the figure-eight one-way switch shrinks and moves above the single redirecting piece.

[0028] When the reciprocating elastic component drives the movable rod and the figure-eight one-way switch to move downward, the large end of the figure-eight one-way switch presses down on the single-unit deflector piece to disengage it from its original locking position.

[0029] As a preferred embodiment of the present invention, the reciprocating elastic component operates automatically based on whether the fabric pulling machine reaches the fabric holding point and the set point.

[0030] As a preferred embodiment of the present invention, a laser cutter is further provided on the outside of the pressing component. The laser cutter is electrically connected to an external control program, which controls the laser cutter to cut the fabric at the fabric holding point or the set point.

[0031] Compared with the prior art, the present invention has the following advantages:

[0032] This invention utilizes a launching device to fix the pressing assembly at the fabric reversal point. As the fabric spreading machine slides in the reversal direction, the fabric is guided by the pressing assembly to spread in the opposite direction, thus forming multiple layers of continuous, long-distance fabric stacks as the spreading machine reciprocates, thereby completing the long-distance fabric spreading operation. Therefore, in this device, the continuous reciprocating fabric spreading operation of the spreading machine achieves long-distance fabric spreading without requiring a large factory space, thereby saving equipment footprint and improving the utilization of space resources.

[0041] 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.

[0042] like Figures 1 to 4 As shown, the present invention provides a long-distance fabric spreading machine for bidirectional multi-layer fabric laying, including a fabric bed 1 and a fabric spreading machine 2 slidably disposed on the fabric bed 1. On the fabric bed 1, fabric holding points 3 and setting points 4 are respectively provided on both sides of the fabric spreading machine 2. The fabric holding points 3 are used to fix the material head on the fabric output side of the fabric spreading machine 2. The setting points 4 are adjustable points set manually. The fabric spreading machine 2 slides back and forth between the fabric holding points 3 as the starting point and the setting points 4 as the ending point, with the two as the turning points, to lay the fabric.

[0043] The fabric spreading machine 2 is provided with a pressing component 5 on the fabric output side. The pressing component 5 is located on both sides of the fabric. The pressing component 5 moves with the fabric spreading machine 2. When the fabric spreading machine 2 reaches a turning point, the pressing component 5 is lowered to fix the fabric at this turning point. The fabric contacts the fixed pressing component 5 and slides in the turning point of the fabric spreading machine 2 to complete the reverse fabric laying.

[0044] Among them, the bottom layer of fabric that is in direct contact with the fabric bed 1 is fixed at both ends by the pressing component 5 to the fabric bed 1.

[0045] The layers of fabric above the bottom layer are clamped and fixed layer by layer by the pressing component 5.

[0046] In this device, the set point 4 is a manually set movable point. By moving the set point 4 closer to or further away from the fabric holding point 3, the length of a single pass of the fabric spreading machine 2 can be changed, thereby changing the length of the fabric pile formed by multiple passes of fabric spreading.

[0047] The function of the fabric holding point 3 is twofold: firstly, to serve as the starting point of the fabric spreading machine 2, and secondly, to clamp and fix the fabric head from the fabric output side of the fabric spreading machine 2. It can be set inside the fabric bed 1, without protruding from the surface of the fabric bed 1. The fabric head is then inserted into its interior and clamped, thus achieving fixation. The specific clamping components are already mature technologies in the prior art and will not be described in detail here.

[0048] In this device, the fabric spreading machine 2 moves from the fabric holding point 3 to the set point 4. Then, the pressing component 5 below the set point 4 presses the fabric on the fabric bed 1. When the fabric spreading machine 2 moves in the reverse direction, the fabric will be output in the reverse direction guided by the pressing component 5. After the fabric spreading machine 2 moves to the fabric holding point 3, the same operation is performed to achieve multi-layer fabric laying without interruption.

[0049] The pressing component 5 includes a locking part 6 and a rolling part 7. The pressing component 5 is connected to the fabric bed 1 and adjacent pressing components 5 through the locking part 6. The pressing component 5 is pulled out from between adjacent fabrics through the rolling part 7.

[0050] The rolling part 7 includes a ball bearing 71 and a driving mechanism 72. The driving mechanism 72 is used to drive the ball bearing 71 to contact the fabric outside the pressing member 5 and to press the fabric outside the pressing member 5 against the fabric bed 1 or the adjacent pressing member 5. The ball bearing 71 rolls on the fabric bed 1 or the adjacent pressing member 5 to pull the pressing member 5 out from between the fabrics.

[0051] The pressing component 5 includes a single-unit deflector plate, and the ball bearing 71 is disposed inside the single-unit deflector plate. The ball bearing 71 moves and protrudes from the upper and lower surfaces of the single-unit deflector plate under the drive of the drive mechanism 72, so as to press the fabric against the fabric bed 1 or the adjacent single-unit deflector plate.

[0052] The ball bearings 71 on adjacent deflector segments are staggered, and the ball bearings 71 roll in contact with the adjacent deflector segments where no ball bearings 71 are provided.

[0053] The pressing component can be a single-piece deflector plate, with both the locking and rolling parts located inside the single-piece deflector plate. The edges of the single-piece deflector plate can be set to semi-circular, allowing for smoother fabric placement when in contact with the fabric.

[0054] Locking part 6 can be as Figure 2 The setup shown is a pin and a socket. After the pin is inserted into the socket, the locking mechanism inside the socket automatically locks it in place, preventing it from retracting. When the bottommost single-unit redirector piece is locked to the fabric bed, the pin can be located on the single-unit redirector piece, and the socket can be located on the fabric bed 1.

[0055] The main function of the rolling part 7 is to facilitate the extraction of individual deflector pieces from the multi-layered fabric stack. Specifically, since the fabric stack formed by this device is composed of overlapping layers, and multiple individual deflector pieces are arranged longitudinally, when it is necessary to remove the individual deflector pieces, they can be removed gradually from top to bottom. This way, each individual deflector piece is not subjected to excessive pressure, making it easier to remove.

[0056] However, during the actual fabric laying process, some areas of the fabric roll may have defects, such as color differences, holes, broken yarns, stains, etc. In this case, the fabric pile end can be adjusted at or near the defect location, and then the defect location can be treated to minimize waste. Therefore, if it is necessary to pull out the single-unit deflector from the middle or lower layer at this time, the single-unit deflector will be difficult to pull out directly due to the pressure of the upper single-unit deflector and the friction of the multiple layers of fabric.

[0057] The pressure of the upper single-unit deflector can be reduced by decreasing the weight of the single-unit deflector. The friction of the multi-layer fabric is related to the properties of the fabric and the weaving method. Polyester or knitted fabrics have greater friction. Therefore, this device is equipped with a rolling part 7. By using the ball bearing 71 to connect with the fabric and the single-unit deflector / fabric bed, the resistance during its movement is reduced, so that it can be easily pulled out.

[0058] Specifically, such as Figure 2 As shown, the ball bearing 71 is normally located inside the single-piece deflector and does not protrude from its surface. When the single-piece deflector needs to be removed, the drive mechanism 72 drives the ball bearing 71 to protrude from the surface of the single-piece deflector and contact the outer fabric. This allows the single-piece deflector to be easily removed by the rolling motion of the ball bearing 71. The specific structure is as follows: Figure 2 As shown, the ball bearing 71 is mounted on the movable plate, which is slidably mounted inside the single redirector segment, and a drive structure 72 is set between the two to drive them to move up and down.

[0059] The specific structure of the drive mechanism 72 can be formed by a rotating rod and an ellipse positioned between the moving plates on the rotating rod. The rotating rod drives the ellipse to rotate between the moving plates, rotating the major axis of the ellipse vertically, thereby lifting the moving plates and protruding the ball bearing 71 out of the surface of the single-unit redirector plate.

[0060] Furthermore, the balls 71 on the individual steering segments are staggered. This allows the balls 71 to protrude from their surfaces and then abut against the surfaces of adjacent individual steering segments where no balls 71 are provided when the adjacent individual steering segments are pulled out. This makes the movement smoother and prevents the balls 71 from falling into the recessed positions of adjacent individual steering segments after protruding.

[0061] The specific arrangement of the balls 71 can be set in rows to form an interlaced or arc shape, but the arrangement of the balls 71 needs to ensure that the force is evenly distributed so as to support the entire single redirector segment.

[0062] In addition, in practical applications, a synchronous rotation device can be set to drive the drive mechanism 72 of all individual steering segments simultaneously, so that the balls 71 of multiple individual steering segments can protrude at the same time, making it more convenient to use.

[0063] Multiple individual steering segments are connected on one side by a connector 8, which can drive the multiple individual steering segments to move synchronously to one side so that they can be extracted at the same time.

[0064] Furthermore, removing individual steering segments is rather cumbersome. This can be addressed by installing connecting members 8 on the same side of each individual steering segment. Multiple individual steering segments can be connected together using these connecting members 8 to form a single unit. Then, pulling the connecting members 8 allows all individual steering segments to be removed together, making the process much more convenient.

[0065] Furthermore, the single steering segment includes two split steering segments whose ends are movably connected. The opposite ends of the two split steering segments are connected in series with the ends of other split steering segments on the same side through a connector 8. The connector 8 pulls all the split steering segments on both sides to move opposite to each other so that the split steering segments can be pulled out synchronously from both sides.

[0066] By setting the individual steering segments as separate units (which can be connected by magnetic attraction or snap-fit), it is easier to remove the individual steering segments by pulling all the individual steering segments from both sides.

[0067] The connecting part 8 can be positioned at the end of the single redirecting piece, that is, not on the side close to the fabric spreading machine 2, but on the side perpendicular to the side close to the fabric spreading machine 2.

[0068] The fabric feeding machine 2 is also equipped with a launching device 10 on the fabric output side. The launching device 10 is connected to the pressing component 5 and is used to lower the pressing component 5 onto the fabric bed 1 or an adjacent pressing component 5.

[0069] The launching device 10 connects multiple pressing components 5 in series to form a longitudinal stack, and there are gaps between adjacent pressing components 5. The launching device 10 drives multiple pressing components 5 to move down synchronously, and the pressing components 5 are placed down in sequence to replace the former one by one.

[0070] The distance by which the launching device 10 drives the pressing component 5 to move downward each time is equal to the sum of the gap between adjacent pressing components 5 and the thickness of the pressing component 5 itself.

[0071] Furthermore, a launching device 10 is also provided on the fabric output side of the fabric spreading machine 2. The main function of the launching device 10 is to lower and fix the pressing component 5 onto the fabric. Specifically, multiple individual deflector plates are connected in series on the fabric output side of the fabric spreading machine 2 in a longitudinally stacked manner. Then, whenever the fabric spreading machine 2 moves to the fabric holding point 3 or the set point 4, it launches an individual deflector plate to press down the fabric at this position.

[0072] Therefore, the transmitting device 10 can be electrically connected to the electronic control system to realize inductive automatic transmission.

[0073] The main method of launch is to replace the former (the lower single-unit steering segment) with the latter (the upper single-unit steering segment). After the first single-unit steering segment moves down, the next single-unit steering segment moves forward to replace the previous one's position, thereby gradually lowering all the single-unit steering segments.

[0074] Specifically, the launching device 10 includes a fixed cylinder 101, and a plurality of snap-fit ​​positions 11 are provided on the outer wall of the fixed cylinder 101. There is a gap between adjacent snap-fit ​​positions 11. Each snap-fit ​​position 11 is movably snapped with a single deflector piece, and each single deflector piece can be adapted to connect with the snap-fit ​​position 11 below it.

[0075] The fixed cylinder 101 is connected to the lowering structure 12. The lowering structure 12 drives the single-unit redirection piece to disengage from its original snap-fit ​​position 11 and connect with the snap-fit ​​position 11 below it and the fabric bed 1 / single-unit redirection piece.

[0076] The lowering structure 12 includes a movable rod 121, a figure-eight one-way switch 122, and a reciprocating elastic component. The movable rod 121 is sleeved inside the fixed cylinder 101 and is connected to the reciprocating elastic component. The reciprocating elastic component drives the movable rod 121 to move back and forth along the length of the fixed cylinder 101.

[0077] The small end of the figure-eight one-way switch 122 is fixedly connected to the outer wall of the movable rod 121, while the large end is positioned downwards and can move towards each other to narrow the opening.

[0078] The fixed cylinder 101 is provided with a longitudinal long slot 13, and the figure-eight one-way switch 122 is disposed in the longitudinal long slot 13.

[0079] Specifically,

[0080] When the reciprocating elastic component drives the movable rod 121 and the figure-eight one-way switch 122 to move upward, the large end of the figure-eight one-way switch 122 shrinks and moves to above the single-unit redirection segment.

[0081] When the reciprocating elastic component drives the movable rod 121 and the figure-eight one-way switch 122 to move downward, the large head of the figure-eight one-way switch 122 presses down on the single-unit deflector piece to disengage it from its original locking position 11.

[0082] The reciprocating elastic component works automatically depending on whether the fabric pulling machine 2 reaches the fabric holding point 3 and the set point 4.

[0083] In this device, such as Figure 4 As shown, each individual deflector is snapped onto the fixing cylinder 101 by a snap-fit ​​position 11. The connection between the individual deflector and the snap-fit ​​position 11 is accomplished through a locking bead structure, i.e., the umbrella rib has a locking bead structure. Under normal circumstances, it will not come out of the snap-fit ​​position 11. When an external force is applied, the locking bead on it retracts. When it encounters a snap-fit ​​position 11 that needs to be recessed, it will extend under the action of a spring and snap onto the snap-fit ​​position 11 again.

[0084] Therefore, this device uses this method to gradually lower the individual redirection segments one by one.

[0085] The device's descent is driven by a lowering structure 12, which includes a movable lever 121 and a figure-eight one-way switch 122. The figure-eight one-way switch 122 can only retract inwards (achieved via a torsion spring), allowing the individual deflector segment to fall, but not to open excessively in the opposite direction (the opening angle is greater than its normal angle). This causes the movable lever to move the figure-eight one-way switch 122 upwards. At this point, the switch shrinks under the obstruction of the individual deflector segment, allowing it to reach above the segment. Then, the movable lever 121 presses down, causing its larger end to press against the individual deflector segment. Since the larger end can no longer open, the individual deflector segment is disengaged from the locking position 1, causing it to fall. In actual manufacturing, the connection force between the individual deflector segment and the latching position 11 is greater than the thrust of the figure-eight one-way switch 122 when it moves upward, to prevent the figure-eight one-way switch 122 from disconnecting the individual deflector segment and the latching position 11 when it moves upward. The connection force between the individual deflector segment and the latching position 11 is less than the thrust of the figure-eight one-way switch 122 when it moves downward, so that the figure-eight one-way switch 122 can push the individual deflector segment and the latching position 11 to disconnect when it moves downward.

[0086] The reciprocating elastic component drives the movable rod 121 to move up and down reciprocally. This is a conventional structure in the prior art and is not shown in the attached drawings.

[0087] A laser cutter is also provided on the outside of the pressing component 5. The laser cutter is electrically connected to an external control program, which controls the laser cutter to cut the fabric at the fabric holding point 3 or the set point 4. The use of the laser cutter makes the device more flexible, allowing it to cut at the required location. For example, if the fabric spreading machine has a single pass of 2m and the external setting requires 8m of fabric to be spread, the laser cutter can be set to cut the fabric at the holding point after the fabric spreading machine has traveled four passes, thus obtaining the required amount of fabric.

[0088] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
