Description

Technical Field

[0001] The embodiment of the present application relates to the technical field of textile machinery, and specifically to a cloth auxiliary unfolding device. Background Art

[0002] A cloth auxiliary unfolder is a textile mechanical device that can unfold cloth easily and smoothly during the textile production process, thereby preventing the cloth from wrinkling or being damaged during the unfolding process.

[0036] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0037] The present application embodiment provides a cloth auxiliary unfolding device, which includes a device support 1, a bearing mechanism, an unfolding mechanism and a connecting mechanism. Figure 1-Figure 2As shown, the bearing mechanism is arranged at one end of the equipment support 1. The bearing mechanism is used to carry the first reel 21 with the first cloth 31 rolled up and the second reel 22 with the second cloth 32 rolled up. The first reel 21 and the second reel 22 are arranged from top to bottom. The unfolding mechanism is arranged at the other end of the equipment support 1. The unfolding mechanism includes a group of first guide shafts Z1, a group of second guide shafts Z2, a guide block K and a group of traction shafts Z3. The first cloth 31 passes through a group of first guide shafts Z1, a guide block K and a group of traction shafts Z3 in sequence to be unfolded. The second cloth 32 passes through a group of second guide shafts Z2, a guide block K and a group of traction shafts Z3 in sequence to be unfolded. As shown Figure 3-Figure 6 As shown, the connecting mechanism is arranged on the guide block K. The connecting mechanism includes a first infrared sensor Q1, a first conveying roller S1, a second infrared sensor Q2, and a second conveying roller S2. The first infrared sensor Q1 and the first conveying roller S1 are arranged on the unfolding path of the first cloth 31, and the first infrared sensor Q1 is close to the first guide axis Z1 relative to the first conveying roller S1. The second infrared sensor Q2 and the second conveying roller S2 are arranged on the unfolding path of the second cloth 32, and the second infrared sensor Q2 is close to the second guide axis Z2 relative to the second conveying roller S2. The first infrared sensor Q1 and the second infrared sensor Q2 can drive one of the first conveying roller S1 and the second conveying roller S2 to rotate, and the first conveying roller S1 and the second conveying roller S2 are transmission-connected.

[0038] In the embodiment of the present application, one of the first fabric 31 or the second fabric 32 can be unfolded first, and then the other can be quickly connected by the connecting mechanism. Figures 1 to 3 An example explanation is given below:

[0039] In the first example:

[0040] One end of the first cloth 31 first passes between the two first guide shafts Z1, then passes through the guide block K, and finally passes between the two traction shafts Z3. The traction shafts Z3 rotate, and the two traction shafts Z3 simultaneously apply force to the first cloth 31, pulling the first cloth 31 to unwind from the first reel 21.

[0041] In the above process, one end of the second cloth 32 first passes through between the two second guide shafts Z2 and then passes through the guide block K, so that the second conveying roller S2 presses one end of the second cloth 32 .

[0042] During the unfolding process of the first cloth 31, the first infrared sensor Q1 continuously detects the first cloth 31. Until the first cloth 31 is fully unfolded and the other end of the first cloth 31 passes the first infrared sensor Q1, the first infrared sensor Q1 can no longer detect the first cloth 31. At this time, the first infrared sensor Q1 controls one of the first conveying roller S1 and the second conveying roller S2 to rotate, and the rotating one of the first conveying roller S1 and the second conveying roller S2 drives the other to rotate, that is, the first conveying roller S1 and the second conveying roller S2 rotate at the same time. When the second conveying roller S2 rotates, the second conveying roller S2 and the guide block K simultaneously apply force to one end of the second cloth 32, and make one end of the second cloth 32 reach between the two traction shafts Z3, and the two traction shafts Z3 simultaneously apply force to the second cloth 32, pulling the second cloth 32 to unfold from the second reel 22.

[0043] In the second example:

[0044] One end of the second cloth 32 first passes between the two second guide shafts Z2, then passes through the guide block K, and then passes between the two traction shafts Z3. The traction shafts Z3 rotate, and the two traction shafts Z3 simultaneously apply force to the second cloth 32, pulling the second cloth 32 to unwind from the second reel 22.

[0045] In the above process, one end of the first cloth 31 first passes through between the two first guide shafts Z1 and then passes through the guide block K, so that the first conveying roller S1 presses one end of the first cloth 31 .

[0046] During the unfolding process of the second cloth 32, the second infrared sensor Q2 continuously detects the second cloth 32. Until the second cloth 32 is fully unfolded and the other end of the second cloth 32 passes the second infrared sensor Q2, the second infrared sensor Q2 can no longer detect the second cloth 32. At this time, the second infrared sensor Q2 controls one of the first conveying roller S1 and the second conveying roller S2 to rotate, and the rotating one of the first conveying roller S1 and the second conveying roller S2 drives the other to rotate, that is, the first conveying roller S1 and the second conveying roller S2 rotate at the same time. When the first conveying roller S1 rotates, the first conveying roller S1 and the guide block K simultaneously apply force to one end of the first cloth 31, and make one end of the first cloth 31 reach between the two traction shafts Z3, and the two traction shafts Z3 simultaneously apply force to the first cloth 31, pulling the first cloth 31 to unfold from the first reel 21.

[0047] Please continue to see Figure 1 The equipment support 1 may include a substantially rectangular support body and four trapezoidal support parts. The bearing mechanism may be arranged on one side of the support body along the length direction, and the unfolding mechanism may be arranged on the other side of the support body along the length direction. The four support parts may be arranged at the four corners of the support body.

[0048] The first guide shaft Z1 , the second guide shaft Z2 , the traction shaft Z3 , the first conveying roller S1 , and the second conveying roller S2 may all be cylindrical rollers.

[0049] The first infrared sensor Q1 and the second infrared sensor Q2 may both be existing technologies. For example, the models of the first infrared sensor Q1 and the second infrared sensor Q2 may both adopt existing TCRT models, and the embodiment of the present application does not specifically limit this.

[0050] In some embodiments, see Figures 3 to 6 The guide block K includes a first through groove TC1 and a second through groove TC2. The first through groove TC1 facilitates the first cloth 31 to pass through. The first infrared sensor Q1 is fixed to the groove wall of the first through groove TC1. The groove wall of the first through groove TC1 is also provided with a first slide groove, in which a first slider K1 is installed, and the first slider K1 is rotatably connected to the first conveying roller S1. The second through groove TC2 facilitates the second cloth 32 to pass through. The groove wall of the second through groove TC2 fixes the second infrared sensor Q2. The groove wall of the second through groove TC2 is also provided with a second slide groove, in which a second slider K2 is installed, and the second slider K2 is rotatably connected to the second conveying roller S2.

[0051] In this embodiment, the first cloth 31 passing through the two first guide shafts Z1 can pass through the guide block K from the first through slot TC1 and pass through the two traction shafts Z3. In the process of the first cloth 31 passing through the first through slot TC1, the first infrared sensor Q1 provided on the slot wall of the first through slot TC1 can detect the distance between itself and the cloth, and the distance between itself and the slot wall on the opposite side in real time. When the distance detected by the first infrared sensor Q1 is the distance between itself and the cloth, it is considered that the first cloth 31 is in the process of unfolding. When the distance detected by the first infrared sensor Q1 is the distance between itself and the slot wall on the opposite side, it is considered that the first cloth 31 has been fully unfolded. At this time, the first conveying roller S1 and the second conveying roller S2 can be controlled to rotate based on the distance signal detected by the first infrared sensor Q1 to continue the second cloth 32.

[0052] In the above process, since the first conveying roller S1 may or may not abut against the first cloth 31, the position of the first conveying roller S1 is different in these two cases. Therefore, by rotating the first conveying roller S1 to connect to the first slider K1, the first slider K1 is slidably set in the first through groove TC1, so that the first slider K1 can slide in the first slide groove and drive the position of the first conveying roller S1 to change. Similarly, the position change of the second conveying roller S2 can be similar to the first conveying roller S1, which can be achieved through the second slider K2 and the second slide groove, and will not be repeated here.

[0053] Similarly, the second cloth 32 passing through the two second guide shafts Z2 can pass through the guide block K from the second through slot TC2 and pass through the two traction shafts Z3. In the process of the second cloth 32 passing through the second through slot TC2, the second infrared sensor Q2 provided on the slot wall of the second through slot TC2 can detect the distance between itself and the cloth, and the distance between itself and the slot wall on the opposite side in real time. When the distance detected by the second infrared sensor Q2 is the distance between itself and the cloth, it is considered that the second cloth 32 is in the process of unfolding. When the distance detected by the second infrared sensor Q2 is the distance between itself and the slot wall on the opposite side, it is considered that the second cloth 32 has been fully unfolded. At this time, the first conveying roller S1 and the second conveying roller S2 can be controlled to rotate based on the distance detected by the second infrared sensor Q2 to continue the first cloth 31.

[0054] The first infrared sensor Q1 may be embedded in the groove wall of the first through groove TC1, and the second infrared sensor Q2 may be embedded in the groove wall of the second through groove TC2.

[0055] In some embodiments, please see Figure 4 and Figure 6 A first spring H1 is also provided in the first chute, one end of the first spring H1 abuts against the bottom of the first chute, and the other end of the first spring H1 abuts against the peripheral wall of the first conveying roller S1. A second spring H2 is also provided in the second chute, one end of the second spring H2 abuts against the bottom of the second chute, and the other end of the second spring H2 abuts against the peripheral wall of the second conveying roller S2.

[0056] In this embodiment, in the process of splicing the first cloth 31, the first spring H1 can push the first conveying roller S1 to press on the surface of the first cloth 31, thereby improving the conveying effect of the first cloth 31 and facilitating the successful splicing of the first cloth 31. Similarly, in the process of splicing the second cloth 32, the second spring H2 can push the second conveying roller S2 to press on the surface of the second cloth 32, thereby improving the conveying effect of the second cloth 32 and facilitating the successful splicing of the second cloth 32.

[0057] Wherein, both the first spring H1 and the second spring H2 can be set as straight springs. The bottom of the first chute can be a chute wall opposite to the chute opening into which the first conveying roller S1 enters, and a fixing hole can be set at the bottom of the first chute, and one end of the first spring H1 can be embedded in the fixing hole. The other end of the first spring H1 can abut against the peripheral wall of the first conveying roller S1. The manner in which one end of the second spring H2 abuts against the bottom of the second chute and the other end of the second spring H2 abuts against the peripheral wall of the second conveying roller S2 can be similar to the manner in which one end of the first spring H1 abuts against the bottom of the first chute and the other end of the first spring H1 abuts against the peripheral wall of the first conveying roller S1, which will not be repeated here.

[0058] In some embodiments, please see Figure 6 , one end of the first conveying roller S1 extends out of the first slider K1, and the extended part of the first conveying roller S1 is sleeved with the first sprocket LL1 (blocked and not shown). One end of the second conveying roller S2 extends out of the second slider K2, and the extended part of the second conveying roller S2 is sleeved with the second sprocket LL2. The first sprocket LL1 and the second sprocket LL2 are connected by the first chain L1. One of the first conveying roller S1 and the second conveying roller S2 is connected to the first motor DJ1. The side of the guide block K is fixedly connected to the first support plate B1, and the surface of the first support plate B1 is fixedly connected to two first telescopic rods G1, the telescopic end of the first telescopic rod G1 is fixedly connected to the second support plate B2, and the first motor DJ1 is fixed to the second support plate B2.

[0059] In this embodiment, the start and stop of the first motor DJ1 can be controlled based on the signal detected by the first infrared sensor Q1 or the second infrared sensor Q2, thereby controlling the rotation of the first conveying roller S1 or the second conveying roller S2. One of the first conveying roller S1 or the second conveying roller S2 can drive the other to rotate through the first sprocket LL1, the second sprocket LL2 and the first chain L1, so as to continue the first cloth 31 or the second cloth 32.

[0060] Considering the position change of the first conveying roller S1 or the second conveying roller S2 in the above-mentioned embodiment, the position change of the first motor DJ1 is controlled by setting the first support plate B1, the first telescopic rod G1 and the second support plate B2, so that the position of the first motor DJ1 can adapt to the position of the first conveying roller S1 or the second conveying roller S2. Specifically, the first support plate B1, the first telescopic rod G1 and the second support plate B2 control the position change of the first motor DJ1, and the position of the second support plate B2 is changed by controlling the extension and contraction of the first telescopic rod G1, and the first motor DJ1 is fixed to the second support plate B2 so as to change its position with the position of the second support plate B2.

[0061] The first slider K1 may be provided with a first through hole to facilitate the end of the first conveying roller S1 to pass through. The second slider K2 may be provided with a second through hole to facilitate the end of the second conveying roller S2 to pass through.

[0062] One end of the first conveying roller S1 can be interference connected to the first sprocket LL1, and one end of the second conveying roller S2 can be interference connected to the second sprocket LL2. One end of the first conveying roller S1 and one end of the second conveying roller S2 are located on the same side, so that the first sprocket LL1 and the second sprocket LL2 are connected through the first chain L1.

[0063] The first support plate B1 can be fixed to the side wall of the guide block K by bolts. The first telescopic rod G1 can be a non-powered telescopic rod. The fixed end of the first telescopic rod G1 can be connected to the plate surface of the first support plate B1 by screws, and the retracted end of the first telescopic rod G1 can also be connected to the plate surface of the second support plate B2 by screws. An angle can be set between the second support plate B2 and the first support plate B1.

[0064] In some embodiments, see Figure 7 , two first guide shafts Z1 in one group are arranged in the vertical direction, and the ends of the two first guide shafts Z1 are both provided with third sprockets LL3, and the two third sprockets LL3 are connected by the second chain L2.

Two traction shafts Z3 in one group are arranged in the vertical direction, and a second motor DJ2 is connected to one traction shaft Z3.

[0065] In this embodiment, when wrinkles appear during the unfolding of the first cloth 31 or the second cloth 32, under the action of the force of the traction shaft Z3, the two first guide shafts Z1 are connected by transmission through the third sprocket LL3 and the second chain L2, so that the two first guide shafts Z1 can apply a certain reverse force to the first cloth 31 during the passing of the first cloth 31, so as to smooth the first cloth 31; similarly, the two second guide shafts Z2 are connected by transmission through the fourth sprocket LL4 and the third chain L3, so that the two second guide shafts Z2 can apply a certain reverse force to the second cloth 32 during the passing of the second cloth 32, so as to smooth the second cloth 32, thereby improving the flatness of the unfolding of the first cloth 31 and the second cloth 32.

[0066] In some embodiments, please see Figure 7 The equipment support 1 includes two side supports 11, and the two side supports 11 are arranged opposite to each other. Each side support 11 includes a first rod, a second rod and a third rod, the second rod is connected to the side of the first rod close to the bearing mechanism, and the third rod is connected to the side of the first rod facing away from the second rod. A group of first guide shafts Z1 are rotatably connected to the first rod. A group of second guide rods are rotatably connected to the second rod. A group of traction shafts Z3 are rotatably connected to the third rod.

[0067] In this embodiment, when a group of first guide shafts Z1 are rotatably connected to the first rod, the first rod can provide a constant position for the first guide shaft Z1, thereby preventing the first guide shaft Z1 from being displaced during the unfolding process of the first cloth 31, thereby affecting the guiding efficiency of the first cloth 31. Similarly, when a group of second guide shafts are rotatably connected to the second rod, the guiding efficiency of the second cloth 32 can also be improved. When a group of traction shafts Z3 are rotatably connected to the third rod, the unfolding efficiency of the first cloth 31 and the second cloth 32 can be improved.

[0068] The first guide shaft Z1 can be rotatably connected to the first rod in a pin-connected manner. A group of second guide rods can be rotatably connected to the second rod in a pin-connected manner. A group of traction shafts Z3 can be rotatably connected to the third rod in a pin-connected manner.

[0069] In some embodiments, please Figure 1 , Figure 2 and Figure 8 The bearing mechanism includes two vertical brackets 12, a first bearing assembly, a second bearing assembly and an adjustment assembly. The two vertical brackets 12 are arranged opposite to each other. The first bearing assembly includes two first input arms 13 and a first rotating shaft ZZ1. The two first input arms 13 are rotatably connected to the outer sides of the two vertical brackets 12 in a one-to-one correspondence and are located above the vertical brackets 12. Both ends of the first rotating shaft ZZ1 are installed in the first U-shaped groove C1 of the vertical bracket 12 and are installed in the groove of the first input arm 13. The first rotating shaft ZZ1 is used to install the first reel 21 with the first cloth 31 rolled up. The second bearing assembly includes two second input arms 14 and a second rotating shaft ZZ2. The two second input arms 14 are installed in a one-to-one correspondence on the outer sides of the two vertical brackets 12 and are located below the vertical brackets 12. Both ends of the second rotating shaft ZZ2 are installed in the second U-shaped groove C2 of the vertical bracket 12 and are installed in the groove of the second input arm 14. The second rotating shaft ZZ2 is used to install the second reel 22 with the second cloth 32 rolled up. The adjustment assembly is arranged at the top of the two vertical brackets 12, and the adjustment assembly includes a third motor DJ3, a reel Z4, two first traction ropes 161 and two second traction ropes 162. The output shaft of the third motor DJ3 is connected to the reel Z4, and the reel Z4 is wound with two first traction ropes 161 and two second traction ropes 162. The two first traction ropes 161 are connected to the two first input arms 13 one by one, and the two second traction ropes 162 are connected to the two second input arms 14 one by one. Among them, the specific structure of the second bearing assembly is the same as that of the first bearing assembly, which is not shown in the figure.

[0070] In the embodiment of the present application, when the first cloth 31 is fully unfolded, the first reel 21 on the first rotating shaft ZZ1 can be replaced. Similarly, when the second cloth 32 is fully unfolded, the second reel 22 on the second rotating shaft ZZ2 can be replaced. Specifically, one of the first reel 21 or the second reel 22 can be replaced first, and then the other. For ease of understanding, the following is an exemplary description.

[0071] In the first example:

[0072] When replacing the first reel 21, the third motor DJ3 drives the reel Z4 to rotate, so that the two first traction ropes 161 on the reel Z4 are released, and the first input arm 13 is forced to rotate downward by gravity. When the first input arm 13 smoothly swings down to touch the ground, the first rotating shaft ZZ1 can be inserted into the center hole of the new first reel 21, and the first rotating shaft ZZ1 is pushed onto the corresponding first input arm 13. Subsequently, the third motor DJ3 is started again to drive the reel Z4 to wind the first traction rope 161. As the first input arm 13 is gradually lifted and tilted, the first rotating shaft ZZ1 with the new first reel 21 installed will roll into the first U-shaped groove C1 of the first input arm 13, completing the replacement process of the new first reel 21, thereby effectively assisting the rapid connection operation of the first cloth 31.

[0073] It is worth noting that in the above process, due to the heavy weight of the second reel 22 and the second cloth 32 it carries, when the second cloth 32 has not yet been unfolded, the corresponding second input arm 14 cannot swing down due to the obstruction of the weight of the second reel 22 and the second cloth 32.

[0074] In the second example:

[0075] When replacing the second reel 22, the third motor DJ3 drives the reel Z4 to rotate, so that the second traction rope 162 on the reel Z4 is released, and the second input arm 14 is forced to rotate downward by gravity. When the second input arm 14 smoothly swings down to touch the ground, the second rotating shaft ZZ2 can be inserted into the center hole of the new second reel 22, and the second rotating shaft ZZ2 is pushed onto the corresponding second input arm 14. Subsequently, the third motor DJ3 is started again to drive the reel Z4 to wind the second traction rope 162. As the second input arm 14 gradually lifts up and tilts, the second rotating shaft ZZ2 with the new second reel 22 installed will roll into the second U-shaped groove C2 of the second input arm 14, completing the replacement process of the new second reel 22, thereby effectively assisting the rapid connection operation of the second cloth 32.

[0076] It is worth noting that in the above process, due to the heavy weight of the first reel 21 and the first cloth 31 it carries, when the first cloth 31 has not yet been unfolded, the corresponding first input arm 13 cannot swing down due to the obstruction of the weight of the first reel 21 and the first cloth 31.

[0077] The openings of the first U-shaped groove C1 and the second U-shaped groove C2 may both face away from the aforementioned unfolding mechanism.

[0078] In some embodiments, a second telescopic rod G2, a first buffer spring H3 and a first arc-shaped contact piece 151 are provided in the groove of the first input arm 13. The fixed end of the second telescopic rod G2 is fixed to the groove wall of the groove of the first input arm 13, the telescopic end of the second telescopic rod G2 is fixed to the outer wall of the first arc-shaped contact piece 151, the first buffer spring H3 is sleeved on the peripheral wall of the second telescopic rod G2, and the inner wall of the first arc-shaped contact piece 151 abuts the first rotating shaft ZZ1. A third telescopic rod G3, a second buffer spring H4 and a second arc-shaped contact piece 152 are provided in the groove of the second input arm 14, the fixed end of the third telescopic rod G3 is fixed to the groove wall of the groove of the second input arm 14, the telescopic end of the third telescopic rod G3 is fixed to the outer wall of the second arc-shaped contact piece 152, and the second buffer spring H4 is sleeved on the peripheral wall of the third telescopic rod G3.

[0079] In this embodiment, the first buffer spring H3 can play a buffering role when the first rotating shaft ZZ1 enters the first U-shaped groove C1, and the inner wall of the first arc-shaped abutting piece 151 abuts the first rotating shaft ZZ1. The second telescopic rod G2 can guide the first buffer spring H3 to prevent the first buffer spring H3 from bending. The second buffer spring H4 can play a buffering role when the second reel 22 enters the second U-shaped groove C2, and the inner wall of the second arc-shaped abutting piece 152 abuts the second rotating shaft ZZ2. The third telescopic rod G3 can guide the second buffer spring H4 to prevent the second buffer spring H4 from bending.

[0080] The second telescopic rod G2 and the third telescopic rod G3 can both be unpowered telescopic rods.

[0081] In some embodiments, please see Figure 1 and Figure 2 A third support plate B3 is fixedly connected to the top of the side of the vertical bracket 12, and a third motor DJ3 is fixedly installed on the surface of the third support plate B3. The reel Z4 is rotatably connected to the top of the vertical bracket 12, and one end of the reel Z4 is connected to the output shaft of the third motor DJ3.

[0082] In some embodiments, the cloth auxiliary unfolding device further comprises a controller, and the first infrared sensor Q1 and the second infrared sensor Q2 are both communicatively connected to the controller. The first infrared sensor Q1 or the second infrared sensor Q2 is used to control the rotation of the first conveying roller S1 or the second conveying roller S2.

[0083] In this embodiment, during the process of unfolding the first cloth 31 or the second cloth 32, the controller controls the second motor DJ2 to rotate, and the second motor DJ2 controls the two traction shafts Z3 to rotate, thereby realizing the transmission of the first cloth 31 or the second cloth 32, and facilitating the unfolding of the first cloth 31 or the second cloth 32.

[0084] In the process of connecting the first cloth 31 and the second cloth 32 to each other, the first infrared sensor Q1 and the second infrared sensor Q2 transmit the detected signals to the controller, and the controller controls the aforementioned first motor DJ1 to rotate, and the first motor DJ1 controls the first conveying roller S1 or the second conveying roller S2 to rotate, thereby realizing the connection of the first cloth 31 or the second cloth 32.

[0085] The controller may be existing technology, for example, the controller may adopt Deutronic's D-Sinus motor controller. The embodiment of the present application does not specifically limit the controller.

[0086] The controller and the first infrared sensor Q1 and the second infrared sensor Q2 may be connected via a signal line or wirelessly, and the present application embodiment does not specifically limit this. The controller may be remotely set to remotely control the first infrared sensor Q1 and the second infrared sensor Q2.

[0087] It should be noted that the controller of this embodiment can also be connected to the aforementioned third motor DJ3 via a signal to control the rotation of the third motor DJ3 to facilitate the replacement of the first reel 21 and the second reel 22 .

[0088] Finally, it should be noted that the above is only a preferred embodiment of the embodiment of the present application, and is not intended to limit the embodiment of the present application.
