DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In order to solve the problem in the prior art that the cutting mechanism has a low level of intelligence and requires manual adjustment of the position of the cloth and the position of the cutting mechanism, which seriously affects the cutting efficiency of the cloth edge, the present application provides an automatic cloth edge correction cutting mechanism, which can automatically adjust the position of the cloth and the position of the cutting mechanism, so that the cutting mechanism can accurately cut the edge of the cloth, thereby improving the level of intelligence and the cutting efficiency of the cloth edge.

[0030] See Figure 1 and Figure 2The automatic cloth edge correction and cutting mechanism includes a centering mechanism 1, a cutting mechanism 2, and a detection system 3. The centering mechanism 1 is used to adjust the position of the cloth as it travels on the water jet loom. Two cutting mechanisms 2 are located at the rear of the water jet loom, facing each other, and are used to cut the two edges of the cloth. The detection system 3 is used to detect the position of the cloth edges. The detection system 3, the centering mechanism 1, and the cutting mechanism 2 are electrically connected via a control system to enable signal transmission. The centering mechanism 1 uses the cloth edge position information obtained by the detection system 3 to adjust the cloth position so that the cutting blade 205 aligns with the cutting position of the cloth edge.

[0031] See Figure 2 and Figure 3 In this embodiment, the centering mechanism 1 includes a first telescopic mechanism 101 and a second telescopic mechanism 102. The first telescopic mechanism 101 has a first telescopic portion 1011 that can be telescoped in the height direction, and the first telescopic portion 1011 is rotatably connected to a first centering axis 1012; the second telescopic mechanism 102 has a second telescopic portion 1021 that can be telescoped in the height direction, and the second telescopic portion 1021 is rotatably connected to a second centering axis 1022; the first pair of centering axes 1012 and the second pair of centering axes 1022 are arranged opposite to each other, and the outer diameter of the first pair of centering axes 1012 gradually increases in a direction away from the second pair of centering axes 1022, and the outer diameter of the second pair of centering axes 1022 gradually increases in a direction away from the first pair of centering axes 1012.

[0032] See Figure 2 and Figure 3Exemplarily, the first telescopic mechanism 101 includes a support arm 1013, a sliding arm 1014, a drive motor 1015, and a lifting screw 1016. The support arm 1013 is arranged vertically and can be fixedly connected to the body of the water jet loom or fixed to the ground. A lifting slot 1018 is provided on the side wall of the support arm 1013 and is arranged vertically. The sliding arm 1014 is arranged adjacent to the support arm 1013. A slider 1019 is fixedly connected to the side of the sliding arm 1014 facing the support arm 1013, and the slider 1019 slides in the lifting slot 1018. The lifting screw 1016 is connected to the lifting slot 1018 in a vertically rotatable manner. The drive motor 1015 is fixedly connected to the top of the support arm 1013, and its output end is connected to the lifting screw 1016. The lifting screw 1016 passes through the slider 1019 in the lifting groove 1018, and the slider 1019 is threadedly engaged with the driving screw. The first pair of center shafts 1012 are rotatably connected to the sliding arm 1014, and the outer diameter of the first pair of center shafts 1012 gradually decreases in the direction away from the sliding arm 1014. It should be noted that the sliding arm 1014 here is equivalent to the first telescopic part 1011. In this way, the driving motor 1015 drives the lifting screw 1016 to rotate, and the threaded engagement between the lifting screw 1016 and the slider 1019 is used to drive the sliding arm 1014 to rise and fall by using the slider 1019. During the lifting process, the sliding arm 1014 drives the first pair of center shafts 1012 to rise and fall. The structure and working principle of the second telescopic mechanism 102 are the same as those of the first telescopic mechanism 101, and will not be repeated here.

[0033] See Figure 2 and Figure 3 The first pair of central axes 1012 and the second pair of central axes 1022 are disposed opposite each other. Specifically, the ends of the first pair of central axes 1012 with the smallest outer diameters face the ends of the second pair of central axes 1022 with the smallest outer diameters. During fabric movement, the fabric passes over the upper surfaces of the first and second pair of central axes 1012, 1022. When the first pair of central axes 1012 is higher than the second pair of central axes 1022, the fabric moves toward the second pair of central axes 1022, along the direction from the first pair of central axes 1012 to the second pair of central axes 1022. When the first pair of central axes 1012 is lower than the second pair of central axes 1022, the fabric moves toward the first pair of central axes 1012, along the direction from the second pair of central axes 1022 to the first pair of central axes 1012. When the cloth is deflected in position during movement, the detection system 3 can immediately identify the displacement of the deflection. The detection system 3 adjusts the lifting height of the first pair of center axes 1012 and the second pair of center axes 1022 through the control system to achieve position adjustment of the cloth.

[0034] See Figure 4-Figure 6The cutting mechanism 2 is located at the rear of the water jet loom, with the centering mechanism 1 positioned adjacent to it. As the fabric travels, it passes through the centering mechanism 1 before passing through the cutting mechanism 2. The cutting mechanism 2 comprises a support base 201, a transverse member 202, a first drive mechanism, a connecting arm 204, and a cutting blade 205. The support base 201 is fixedly connected to the body of the water jet loom. A first sliding cavity 2011 is defined within the support base 201, into which the transverse member 202 is slidably connected. Along the length direction of the first sliding cavity 2011, the size of the first sliding cavity 2011 is larger than the size of the transverse member 202, so that the transverse member 202 can slide in the first sliding cavity 2011 along the length direction of the first sliding cavity 2011; along the width direction of the first sliding cavity 2011, the size of the first sliding cavity 2011 is equal to the size of the transverse member 202, so as to limit the transverse member 202 to only slide along the length direction of the first sliding cavity 2011.

[0035] The first driving mechanism is used to drive the transverse member 202 to slide in the first sliding cavity 2011 along the length direction of the first sliding cavity 2011. Exemplarily, the first driving mechanism includes a first motor 2031 and a first screw rod 2032. The first screw rod 2032 is rotatably connected in the first sliding cavity 2011. The length direction of the first screw rod 2032 is in the same direction as the length direction of the first sliding cavity 2011. The first screw rod 2032 passes through the bottom wall of the transverse member 202, and the first screw rod 2032 and the bottom wall of the transverse member 202 are threadedly engaged. The first motor 2031 is fixedly connected to the support seat 201. The first motor 2031 is used to drive the first screw rod 2032 to rotate. The first motor 2031 can drive the first screw rod 2032 to rotate by means of a gear box or a coupling. In this way, the first motor 2031 drives the first screw rod 2032 to rotate. During the rotation process, the first screw rod 2032 drives the transverse member 202 to slide in the first sliding cavity 2011 along the length direction of the first sliding cavity 2011. One end of the connecting arm 204 is linked to the transverse member 202, and the cutting knife 205 is rotatably disposed at the end of the connecting arm 204 away from the transverse member 202. In this way, during the movement of the transverse member 202, the transverse member 202 can drive the connecting arm 204 to move. Since the cutting knife 205 is connected to the connecting arm 204, the movement of the connecting arm 204 can drive the cutting knife 205 to move, thereby achieving the effect of adjusting the position of the cutting knife 205 through the drive of the first motor 2031.

[0036] In this embodiment, refer to Figure 4-Figure 6The transverse member 202 is provided with a second sliding cavity 2021, and the length direction of the first sliding cavity 2011 is parallel to the length direction of the second sliding cavity 2021. The automatic cloth edge correction and cutting mechanism also includes a lifting member 206 and a second drive mechanism. The lifting member 206 is slidably connected to the second sliding cavity 2021. Along the length direction of the second sliding cavity 2021, the size of the second sliding cavity 2021 is larger than the size of the lifting member 206, so that the lifting member 206 can slide within the second sliding cavity 2021 along the length direction of the second sliding cavity 2021. Along the width direction of the second sliding cavity 2021, the size of the second sliding cavity 2021 is equal to the size of the lifting member 206, so that the lifting member 206 can only slide along the length direction of the second sliding cavity 2021.

[0037] See Figure 4-Figure 6The second drive mechanism is used to drive the lifting member 206 to slide in the second sliding cavity 2021 along the length direction of the second sliding cavity 2021. Exemplarily, the second drive mechanism includes a second motor 2071 and a second screw rod 2072. The second screw rod 2072 is rotatably connected to the second sliding cavity 2021. The length direction of the second screw rod 2072 is in the same direction as the length direction of the second sliding cavity 2021. The second screw rod 2072 passes through the bottom wall of the lifting member 206. The second screw rod 2072 and the bottom wall of the lifting member 206 are threadedly engaged. The second motor 2071 is fixedly connected to the transverse member 202. The second motor 2071 is used to drive the second screw rod 2072 to rotate. The second motor 2071 can drive the second screw rod 2072 to rotate through a gear box or a coupling. Thus, the second motor 2071 drives the second screw rod 2072 to rotate. During the rotation process, the second screw rod 2072 drives the lifting member 206 to slide in the second sliding cavity 2021 along the length direction of the second sliding cavity 2021. The lifting member 206 is provided with a lifting cavity 2061, and a lifting inclined surface 2062 is provided in the lifting cavity 2061. The connecting arm 204 is linked to one end of the transverse member 202 and enters the lifting cavity 2061 and is slidably connected to the lifting inclined surface 2062. In this way, when the lifting member 206 is driven by the second screw rod 2072 to move, the end of the connecting arm 204 entering the lifting chamber 2061 can move along the lifting inclined surface 2062 to adjust the height of the connecting arm 204. Specifically, when the end of the connecting arm 204 entering the lifting chamber 2061 enters the highest point of the lifting inclined surface 2062, the connecting arm 204 drives the cutting knife 205 to the highest point, so that the cutting knife 205 is in a non-cutting state. In this state, there is a distance between the cutting knife 205 and the cloth, and the cutting knife 205 cannot cut the cloth; when the end of the connecting arm 204 entering the lifting chamber 2061 enters the lowest point of the lifting inclined surface 2062, the connecting arm 204 drives the cutting knife 205 to the lowest point, so that the cutting knife 205 is in a cutting state. In this state, the cutting knife 205 contacts the cloth, and the cutting knife 205 cuts the cloth.

[0038] In this embodiment, see Figure 4-Figure 7The connecting arm 204 includes a main body box 2041, an extension rod 2042, and a lifting shaft 2043. A gear set is provided in the main body box 2041. The gear set is a conventional gear system and will not be described in detail here. A cutting motor 208 is fixed outside the main body box 2041. The output end of the cutting motor 208 is connected to the input end of the gear set. The output end of the gear set is connected to a rotating shaft 209. The cutting knife 205 is fixed on the rotating shaft 209. The cutting motor 208 drives the rotating shaft 209 to rotate through the gear set, and the rotating shaft 209 drives the cutting knife 205 to rotate. The extension rod 2042 is fixedly connected to one end of the main body box 2041. The end of the main body box 2041 away from the extension rod 2042 extends downward and is used to install the cutting knife 205. The extension rod 2042 passes upward through the support base 201, the transverse member 202, and the lifting member 206, and then enters the lifting chamber 2061. The lifting shaft 2043 is connected to the end of the extension rod 2042 that enters the lifting chamber 2061. The lifting shaft 2043 overlaps the lifting slope 2062. In this way, as the lifting member 206 slides along the length of the second sliding chamber 2021, the lifting shaft 2043 can move along the lifting slope 2062 to adjust the height of the connecting arm 204.

[0039] In this embodiment, see Figure 4-Figure 6 The lifting shaft 2043 is rotatably connected to the extension rod 2042. Alternatively, the lifting shaft 2043 is provided with a bearing, the outer ring of which overlaps the lifting inclined surface 2062. This arrangement enables the friction between the lifting shaft 2043 and the lifting inclined surface 2062 to be rolling friction, reducing friction, thereby reducing wear between the lifting shaft 2043 and the lifting inclined surface 2062 and extending the service life.

[0040] In this embodiment, see Figure 4-Figure 6 and Figure 8 The bottom wall of the lifting chamber 2061 is provided with a sliding groove 2063. The length of the sliding groove 2063 is parallel to the length of the second sliding chamber 2021. The extension rod 2042 passes through the sliding groove 2063. Along the length of the second sliding chamber 2021, the sliding groove 2063 is larger than the extension rod 2042. Thus, along the length of the second sliding chamber 2021, the sliding groove 2063 is larger than the extension rod 2042. The sliding groove 2063 provides space for the lifting member 206 to slide, thereby enabling the lifting member 206 to slide within the second sliding chamber 2021.

[0041] In this embodiment, see Figure 4-Figure 6 and Figure 9The bottom wall of the second sliding cavity 2021 is provided with a first limiting hole 2022, through which the extension rod 2042 passes. Along the length of the second sliding cavity 2021, the size of the first limiting hole 2022 is equal to the size of the extension rod 2042. Thus, as the lifting member 206 slides within the second sliding cavity 2021, the first limiting hole 2022 restricts the extension rod 2042 to vertical movement, preventing horizontal displacement. Therefore, guided by the lifting slope 2062, the extension rod 2042 only moves vertically, without horizontal displacement. Furthermore, as the transverse member 202 slides within the first sliding cavity 2011, the first limiting hole 2022 acts as an obstruction, ensuring that the extension rod 2042 moves synchronously with the transverse member 202.

[0042] In this embodiment, see Figure 4-Figure 6 The lifting chamber 2061 is further provided with a first retention section 2064 and a second retention section 2065. The first retention section 2064 is horizontally disposed at one end of the lifting slope 2062, and the second retention section 2065 is horizontally disposed at the other end of the lifting slope 2062. There is a height difference between the first retention section 2064 and the second retention section 2065. The first retention section 2064 is the lowest point of the lifting slope 2062, and the second retention section 2065 is the highest point of the lifting slope 2062. The first retention section 2064 and the second retention section 2065 provide a resting space for the lifting shaft 2043. When the cutting blade 205 is in the cutting state, the lifting shaft 2043 is located in the first retention section 2064. When the cutting blade 205 is in the non-cutting state, the lifting shaft 2043 is located in the second retention section 2065. Since the cutting knife 205 remains in the cutting state and the non-cutting state for the longest time, the first retention section 2064 and the second retention section 2065 provide a platform for the lifting shaft 2043, thereby improving the stability of the cutting knife 205 in the cutting state and the non-cutting state.

[0043] In this embodiment, referring to Figure 10 A sliding groove 2012 is provided on the bottom wall of the first sliding cavity 2011. The sliding groove 2012 extends along the length of the first sliding cavity 2011. The extension rod 2042 passes through the sliding groove 2012, the first limiting hole 2022, and the sliding groove 2063 in sequence before entering the lifting cavity 2061. Along the length of the first sliding cavity 2011, the sliding groove 2012 is larger than the extension rod 2042. This provides space for the transverse member 202 to slide along the length of the first sliding cavity 2011, thereby enabling the transverse member 202 to slide within the first sliding cavity 2011.

[0044] In this embodiment, see Figure 4-Figure 6 、 Figures 8-10A boss 2066 is provided within the lifting chamber 2061. The first retention section 2064, the lifting slope 2062, and the second retention section 2065 are disposed on the boss 2066. The first retention section 2064, the lifting slope 2062, and the second retention section 2065 are connected in sequence. Thus, the boss 2066 provides support for the first retention section 2064, the lifting slope 2062, and the second retention section 2065, thereby increasing their strength and thereby providing a more stable support for the lifting shaft 2043. In addition, two extension rods 2042 are provided on the main box 2041, and the lifting shaft 2043 is connected between the two extension rods 2042. A sliding groove 2063 is provided on both sides of the boss 2066. Two first limiting holes 2022 are provided along the width direction of the second sliding cavity 2021, and two sliding grooves 2012 are provided along the width direction of the first sliding cavity 2011. The first limiting holes 2022, the sliding grooves 2063 and the sliding grooves 2012 correspond to each other one by one, that is, the sliding grooves 2063 on one side of the boss 2066 are provided. 63 is in communication with one of the first limiting holes 2022 and one of the sliding grooves 2012, and the sliding groove 2063 on the other side of the boss 2066 is in communication with the other first limiting hole 2022 and the other sliding groove 2012. In addition, one of the extension rods 2042 passes through the sliding groove 2012, the first limiting hole 2022, and the sliding groove 2063 on one side of the boss 2066, and the other extension rod 2042 passes through the sliding groove 2012, the first limiting hole 2022, and the sliding groove 2063 on the other side of the boss 2066. In this way, the two extension rods 2042 improve the stability of the lifting shaft 2043 during rotation, thereby allowing the lifting shaft 2043 to slide more stably on the lifting inclined surface 2062.

[0045] Detection system 3 is used to detect the width of the fabric edge. Attached to the side of support base 201 facing the fabric, detection system 3 utilizes one or more of a Time of Flight (ToF) sensor, a laser sensor, or a multi-lens camera. These sensors are all capable of measuring distance and detecting the position of the fabric edge. Detection system 3, centering mechanism 1, and cutting mechanism 2 are electrically connected via a control system to facilitate signal transmission.

[0046] The centering mechanism 1 adjusts the position of the fabric using the position information of the fabric edge acquired by the detection system 3, so that the cutting position of the cutting blade 205 aligns with the cutting position of the fabric edge. Specifically, as the fabric moves, the detection system 3 first detects the position information of the fabric edge in real time. This position information may include the coordinates of the fabric edge. If an error is detected between the position information of the fabric edge and the reference position information pre-stored in the control system, the control system controls the two drive motors 1015 of the centering mechanism 1 to adjust the height of the first and second centering axes 1012, 1022, respectively, until the fabric is moved to the correct position. Next, the control system controls the second motor 2071 to maintain the cutting knife 205 in a non-cutting state. The control system adjusts the position of the cutting knife 205 by controlling the first motor 2031 according to the position of the fabric. When the detection system 3 detects that the cutting position of the cutting knife 205 corresponds to the cutting position of the edge of the fabric, the control system controls the second motor 2071 to drive the lifting member 206 to slide along the length direction of the second sliding cavity 2021, so that the cutting knife 205 descends to the cutting state.
