[0045] See Figures 1 to 31 , shows an embodiment of the fabric-laying and cutting integrated cutting bed with dual exchange platforms of the present invention, including a bed body 1, a material-laying device 2, a cutting device 3, a first exchange platform 4 and a second exchange platform 5; the material-laying device 2 is arranged at the front end of the bed body 1, for laying the fabric to be cut on the first exchange platform 4 or the second exchange platform 5; the cutting device 3 is slidably arranged on the bed body 1, for cutting the fabric laid on the first exchange platform 4 or the second exchange platform 5; the first exchange platform 4 and the second exchange platform 5 are both slidably arranged on the bed body 1, and can exchange the front and back positions.

[0046] Specifically, see Figure 4 and Figure 5 In the illustrated embodiment, two exchange platform driving devices 6 are provided on the lower end of the left and right sides of the bed body 1 away from the paving device 2, for driving the first exchange platform 4 and the second exchange platform 5 to exchange their front and rear positions.

[0047] More specifically, see Figure 6 、 Figure 7 and Figure 21In the illustrated embodiment, the exchange platform drive device 6 includes an exchange platform drive motor 601, a driving sprocket 602, a driven sprocket 603, and a chain 604. The exchange platform drive motor 601 is fixedly mounted on the lower rear end of the bed 1, the driving sprocket 602 is fixedly mounted on the output shaft of the exchange platform drive motor 601, and the driven sprocket 603 is fixedly mounted on the lower middle portion of the bed 1. The driving sprocket 902 and the driven sprocket 903 are linked together by a chain. The lower portion of the chain 604 is connected to the rear end of the first exchange platform 4 via a lower connecting plate B605, and the upper portion of the chain 604 is connected to the rear end of the second exchange platform 5 via an upper connecting plate B606. By connecting the upper and lower portions of the chain 604 to the rear ends of the first and second exchange platforms 4, 5, respectively, the first and second exchange platforms 4, 5, can be interchanged under the drive of the chain 604.

[0048] In some other embodiments, the exchange platform drive device 6 includes an exchange platform drive motor 601, a driving pulley, a driven pulley, and a synchronous belt; wherein the exchange platform drive motor 601 is fixedly arranged on the lower side of the rear end of the bed 1, the driving pulley is fixedly arranged on the output shaft of the exchange platform drive motor 601, and the driven pulley is fixedly arranged on the lower side of the middle part of the bed 1. The driving pulley and the driven pulley are connected together by a synchronous belt, the lower part of the synchronous belt is connected to the rear end of the first exchange platform 4, and the upper part of the synchronous belt is connected to the rear end of the second exchange platform 5. By connecting the upper and lower parts of the synchronous belt to the rear ends of the first exchange platform 4 and the second exchange platform 5 respectively, the first exchange platform 4 and the second exchange platform 5 can achieve position exchange under the drive of the synchronous belt.

[0049] It can be understood here that in addition to the above-mentioned embodiments consisting of the exchange platform drive motor 601, the driving sprocket 602, the driven sprocket 603 and the chain 604, or the exchange platform drive motor 601, the driving pulley, the driven pulley and the synchronous belt, the exchange platform drive device 6 can also adopt any other structure that can meet the corresponding functions.

[0050] Specifically, see Figure 1 and Figure 4 In the illustrated embodiment, a vacuum device 7 is provided at the lower end of the bed 1 for communicating with the first exchange platform 4 or the second exchange platform 5. The vacuum device 7 is used to generate negative pressure on the first exchange platform 4 or the second exchange platform 5 to absorb the fabric laid on the first exchange platform 4 or the second exchange platform 5, thereby preventing the fabric from shifting or becoming uneven during cutting, which would affect the cutting effect.

[0051] More specifically, see Figure 4 、 Figure 14 、 Figure 19 and Figure 22In the illustrated embodiment, the vacuuming device 7 includes a vacuum pump 701 and a liftable bellows 702 disposed on the bed 1. The vacuum pump 701 is connected to the liftable bellows 702 via an evacuation pipe (not shown). The liftable bellows 702 is connected to a bellows docking joint 8 disposed at the bottom of the first exchange platform 4 or the second exchange platform 5. The bellows docking joint 8 disposed at the bottom of the first exchange platform 4 is connected to an evacuation pipe interface 9 disposed at the bottom of the first exchange platform 4 via an evacuation pipe (not shown). The bellows docking joint 8 disposed at the bottom of the second exchange platform 4 is connected to an evacuation pipe interface 9 disposed at the bottom of the second exchange platform 4 via an evacuation pipe (not shown). The provision of the liftable bellows 702 enables the vacuuming device 7 to be connected to the bellows docking joints 8 disposed at the bottoms of the first exchange platform 4 and the second exchange platform 5, respectively. That is, a single vacuuming device 7 can simultaneously accommodate two exchange platforms (i.e., the first exchange platform 4 and the second exchange platform 5). During operation, when the first exchange platform 4 moves to above the position of the vacuum device 7, the liftable bellows 702 in the vacuum device 7 can be raised to communicate with the bellows docking joint 8 set at the bottom of the first exchange platform 4; when the second exchange platform 5 moves to above the position of the vacuum device 7, the liftable bellows 702 in the vacuum device 7 can be raised to communicate with the bellows docking joint 8 set at the bottom of the second exchange platform 5; when the first exchange platform 4 and the second exchange platform 5 are in the process of exchanging front and back positions, the liftable bellows 702 of the vacuum device 7 can be lowered to avoid hindering the first exchange platform 4 and the second exchange platform 5 from exchanging positions.

[0052] Further, see Figure 22 The liftable bellows 702 includes a bellows body 702a that docks with the bellows docking joint 8, a bellows slider 702b disposed on the front side of the bellows body 702a, a bellows seat 702c disposed on the front side of the bellows body 702a, one end of which is fixedly connected to the bed 1 and the other end of which is slidably engaged with the bellows slider 702b, and a lifting cylinder 702d fixedly connected to the bellows seat 702c and used to drive the bellows body 702a to rise and fall. The telescopic end of the lifting cylinder 702d is fixedly connected to the bellows body 702a, and the cylinder body of the lifting cylinder 702d is fixedly connected to the bellows seat 702c. Under the action of the lifting cylinder 702d, the bellows body 702a can be driven to rise and fall, thereby achieving communication with the bellows docking joints 8 disposed at the bottom of the first exchange platform 4 and the second exchange platform 5, respectively. The lifting cylinder 702d can be any one of an oil cylinder, a pneumatic cylinder, or an electric cylinder.

[0053] Specifically, see Figure 4 and Figure 5In the illustrated embodiment, two first linear guide rails 10 and two second linear guide rails 11 are provided on the lower ends of the left and right sides of the bed body 1, and the two first linear guide rails 10 are used to slide with the first exchange platform 4, and the two second linear guide rails 11 are located outside the two first linear guide rails 10 and are used to slide with the second exchange platform 5. By setting the first linear guide rails 10 to slide with the first exchange platform 4 and the second linear guide rails 11 to slide with the second exchange platform 5, it is possible to effectively ensure that the first exchange platform 4 and the second exchange platform 5 move linearly along the bed body 1; in addition, by setting the second linear guide rails 11 that slide with the second exchange platform 5 outside the first linear guide rails 10 that slide with the first exchange platform 4, the sliding path of the first exchange platform 4 and the sliding path of the second exchange platform 5 can be staggered to avoid overlapping of the sliding paths of the two, thereby preventing the first exchange platform 4 and the second exchange platform 5 from exchanging positions.

[0054] Specifically, see Figure 4 and Figure 5 In the illustrated embodiment, two sets of contoured guide rails 12 are provided on the lower ends of the left and right sides of the bed body 1, and the two sets of contoured guide rails 12 are located between the two first linear guide rails 10 and the two second linear guide rails 11. The two sets of contoured guide rails 12 are used to slide with the first exchange platform 4 to change the height of the first exchange platform 4 to avoid collision and interference between the first exchange platform 4 and the second exchange platform 5 when the first exchange platform 4 exchanges positions with the second exchange platform 5.

[0055] Further, see Figure 23 Each set of contoured guide rails 12 includes two parallel, opposite, and offset contoured rails 1201. Each contoured rail 1201 is composed of a straight rail 1201a and two trapezoidal rails 1201b at both ends of the straight rail 1201a. The straight rail 1201a is used to lower the tabletop of the first exchange platform 4; the trapezoidal rail 1201b is used to raise the tabletop of the first exchange platform 4. Figures 24 to 31 When the first exchange platform 4 moves onto the straight track 1201a of the contoured track 1201, the table top of the first exchange platform 4 will be lower than the table top of the second exchange platform 5, which makes it convenient to exchange positions with the second exchange platform 5 (that is, the first exchange platform 4 and the second exchange platform 5 are at different heights at this time, which makes it convenient for the two to interchange positions); when the first exchange platform 4 moves onto the trapezoidal track 1201b of the contoured track 1201, the table top of the first exchange platform 4 will be flush with the table top of the second exchange platform 5, which makes it convenient to cooperate with the material laying device 2 to lay the fabric, and to cooperate with the cutting mechanism 3 to cut the fabric.

[0056] Specifically, see Figure 1 and Figure 3In the illustrated embodiment, two third linear guide rails 13 and two linear racks 14 are respectively provided on the outer sides of the left and right sides of the bed body 1 near the upper end, and the two third linear guide rails 13 are both used for sliding cooperation with the cutting device 3, and the two linear racks 14 are both used for meshing cooperation with the cutting device 3.

[0058] More specifically, see Figure 2 and Figure 10 The clamping and pulling mechanism 201 includes a clamping and pulling head beam 2011, two clamping and pulling head beam support plates 2012 arranged at the left and right ends of the clamping and pulling head beam 2011, and a plurality of clamping and pulling heads 2013 arranged on the side of the clamping and pulling head beam 2011 facing the cutting mechanism 202, as well as two first sliders 2014 arranged on the two clamping and pulling head beam support plates 2011 and slidingly engaged with the two third linear guide rails 13 on the bed body 1, and a first moving motor 2015 meshing with the two linear racks 14 on the bed body 1.

[0059] Further, see Figure 2 The clamping and pulling head 2013 is composed of a clamp 2013a and a clamp support 2013b connecting the clamp 2013a and the clamping and pulling head beam support plate 2012; the clamping and pulling head 2013 is used to clamp the free end of the fabric, and under the action of the first moving motor 2015, it pulls the fabric and moves away from the hopper 203, so that the fabric can be laid on the first exchange platform 4 or the second exchange platform 5.

[0060] Further, see Figure 10 A first gear 2016 is provided on the output shaft of the first movable motor 2015 , and the first movable motor 2015 is engaged with the linear rack 14 through the first gear 2016 .

[0064] Further, see Figure 11 The fabric pressing device 2024 includes a fabric pressing cylinder 2024a, an upper fabric pressing plate 2024b, and a lower fabric pressing plate 2024c. The fabric pressing cylinder 2024a is fixedly mounted on the cutter support frame 2021, with its telescopic end connected to the upper fabric pressing plate 2024b. The lower fabric pressing plate 2024c is fixedly mounted on the cutter support frame 2021 and aligned vertically with the upper fabric pressing plate 2024b. The fabric pressing device 2024 facilitates the pressing of the fabric, facilitating the cutting of the fabric by the cutter 222 and reducing cutting errors.

[0065] Specifically, in the present invention, the cutting device 3 is a cutting device commonly used on existing cutting machines, see Figure 12The cutting device 3 primarily comprises a gantry 301, a cutting head 302 slidably mounted on the crossbeam of the gantry 301, a second slider 303 mounted on the upright column of the gantry 301 and slidably engaged with the third linear guide 13, and a second movable motor 304 meshing with the linear rack 14.

[0078] It should be noted that the fabric laying and cutting integrated cutting table with dual exchange platforms provided by the present invention also includes a controller, which is used to control the operation of the entire cutting table. Since the controller belongs to the prior art, it will not be described in detail in this application.

[0079] Figures 24 to 31The figure shows the exchange process between the first exchange platform 4 and the second exchange platform 5; wherein, Figure 24 and Figure 25 Shown is the state before the first exchange platform 4 and the second exchange platform 5 are exchanged; Figure 26 and Figure 27 Shown is the state when the rear end of the first switching platform 4 meets the front end of the second switching platform 5; Figure 28 and Figure 29 Shown is the state when the front end of the first switching platform 4 meets the rear end of the second switching platform; Figure 30 and Figure 31 The diagram shows a state after the first switching platform 4 and the second switching platform 5 are switched.

[0080] The working principle of a fabric laying and cutting integrated cutting table with dual exchange platforms provided in an embodiment of the present invention is as follows:

[0081] When in use, first place the fabric roll 19 on the hopper 203 of the spreading device 2, then clamp the free end of the fabric 18 through the clamping and pulling mechanism 201 of the spreading device 2, and move it along the bed 1 to the rear end of the first exchange platform 4, and then cut the fabric 18 at the front end of the first exchange platform 4 through the cutter 2022, so that the spreading of the first exchange platform 4 is completed. Figure 24 and Figure 25 As shown;

[0082] Next, the first exchange platform 4 and the second exchange platform 5 are interchanged so that the first exchange platform 4 is moved to the rear end of the bed 1 (i.e., the end away from the material spreading device 2), and the second exchange platform 5 is moved to the front end of the bed 1 (i.e., the end close to the material spreading device 2). Figures 26 to 31 ;

[0083] After the first exchange platform 4 and the second exchange platform 5 have completed their position swap, the material spreading device 2 and the cutting device 3 are started to work. The material spreading device 2 spreads the material on the second exchange platform 5 (the material spreading process is the same as that on the first exchange platform 4), and the cutting device 3 cuts the fabric spread on the first exchange platform 4.

[0084] When the fabric on the first exchange platform 4 is cut (the second exchange platform 5 has also finished laying the fabric), the first exchange platform 4 and the second exchange platform 5 are swapped, so that the first exchange platform 4 returns to the front end of the bed 1 and the second exchange platform 5 returns to the rear end of the bed 1;

[0085] When the first exchange platform 4 and the second exchange platform 5 return to their initial positions, the cut fabric on the first exchange platform 4 is first removed, and then the spreading device 2 and the cutting device 3 are started to work, and the spreading device 2 continues to spread the fabric on the first exchange platform 4. At the same time, the cutting device 3 cuts the fabric laid on the second exchange platform 5.

[0086] When the fabric on the second exchange platform 5 is cut (the first exchange platform 4 has also finished laying the fabric again), repeat the first exchange action of the first exchange platform 4 and the second exchange platform 5, and swap the positions of the first exchange platform 4 and the second exchange platform 5, so that the first exchange platform 4 moves to the rear end of the bed 1 again, and the second exchange platform 5 moves to the front end of the bed 1 again;

[0087] When the first exchange platform 4 and the second exchange platform 5 have completed the position exchange again, the cut fabric on the second exchange platform 5 is first removed, and then the spreading device 2 and the cutting device 3 are started to work, and the spreading device 2 continues to spread the fabric on the second exchange platform 5. At the same time, the cutting device 3 continues to cut the fabric laid on the first exchange platform 4.

[0088] When the fabric laid on the first exchange platform 4 is cut again, repeat the above operation, and swap the positions of the first exchange platform 4 and the second exchange platform 5 again, so that the first exchange platform 4 returns to the front end of the bed 1 again, and the second exchange platform 5 returns to the rear end of the bed 1 again. Then, the cut fabric on the first exchange platform 4 is removed again, and then the spreading device 2 and the cutting device 3 are started again. The spreading device 2 continues to spread the fabric on the first exchange platform 4, and the cutting device 3 continues to cut the fabric laid on the second exchange platform 5. Then, the first exchange platform 4 and the second exchange platform 5 are swapped again, so that the first exchange platform 4 is moved to the rear end of the bed 1 again, and the second exchange platform 5 is moved to the front end of the bed 1 again. Repeating the above steps can realize the cycle of the processes of constantly exchanging the positions of the two exchange platforms of the fabric spreading and cutting integrated cutting bed with dual exchange platforms provided by the present invention, constantly alternating the spreading of materials, and constantly alternating the cutting.

[0089] Finally, it should be noted that the above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
