[0029] The cloth falling mechanism of the circular machine is a semi-automatic mechanical cloth falling mode, which is a necessary equipment for large roll production, can significantly improve the cloth falling efficiency of the stopping worker, and improve the overall production efficiency of the circular knitting machine.

[0030] The front end of the cloth falling mechanism of the prior art is provided with a limiting structure for limiting the cloth box, but the limiting structure has a single function, and is only used for limiting the cloth box.

[0031] In order to solve the above technical problems, the present scheme is designed.

[0032] Reference Figures 1 to 3 , the cloth box falling mechanism comprises a main frame 100, a cloth box locking plate 200 and a locking device 300.

[0033] The main frame 100 is provided with a cloth box placing groove for placing the cloth box, and the cloth box placing groove is provided with a placing entrance. When placing the cloth box into the main frame 100, the worker pushes the cloth box into the cloth box placing groove from the placing entrance.

[0034] Specifically, the main frame 100 comprises a base frame 110 and side stops 120 fixedly connected with the base frame 110. The number of the side stops 120 is three, and the three side stops 120 are arranged on three sides of the base frame 110 respectively. The three side stops 120 enclose the cloth box placing groove, and the side stops 120 are used for limiting the cloth box placed in the cloth box placing groove.

[0035] Specifically, in the embodiment, the side stop 120 comprises vertical rods 121 and a horizontal rod 122. The number of the vertical rods 121 is two, and the two vertical rods 121 are parallel to each other. The lower ends of the vertical rods 121 are fixedly connected with the base frame 110. The number of the horizontal rod 122 is one, and the two ends of the horizontal rod 122 are fixedly connected with the upper ends of the two vertical rods 121 respectively. In other embodiments, the number of the vertical rods 121 and the horizontal rod 122 can also be set as multiple respectively, and the multiple vertical rods 121 and the multiple horizontal rods 122 form a mesh structure. The specific structure of the side stop 120 can be selected by the person skilled in the art according to actual needs.

[0036] Specifically, in the embodiment, the main frame 100 is fixedly installed with second flow bars 111, and the second flow bars 111 are installed on the base frame 110. Specifically, the number of the second flow bars 111 is multiple, and the multiple second flow bars 111 are parallel to each other and arranged at intervals. By setting the second flow bars 111, the resistance when the worker pushes the cloth box to move is reduced, so as to reduce the labor intensity of the worker.

[0037] The cloth box locking plate 200 is arranged at the placing entrance and is hingedly connected with the base frame 110 of the main frame 100. The cloth box locking plate 200 can be flipped up and down relative to the main frame 100 about a horizontal axis, so as to close or open the placing entrance. When the cloth box locking plate 200 is flipped to a vertical state, the position of the cloth box can be limited in cooperation with the cloth box placing groove, so as to avoid that the cloth box accidentally separates from the main frame 100 during the cloth falling process.

[0038] Specifically, in the embodiment, the first flow bar 210 is fixedly arranged at the end of the cloth box locking plate 200. Specifically, the outer circumferential surface of the roller of the first flow bar 210 is flush with the end surface of the cloth box locking plate 200, so as to avoid that the roller protrudes too much from the cloth box locking plate 200, causing the weight of the cloth box to be entirely borne by the first flow bar 210, thereby improving the service life of the first flow bar 210.

[0039] Specifically, in the embodiment, the ground contact inclined surface 220 is arranged at the end of the cloth box locking plate 200 away from the main frame 100. The ground contact inclined surface 220 is used to contact the ground, thereby increasing the contact area between the cloth box locking plate 200 and the ground, so as to avoid stress concentration causing damage to the cloth box locking plate 200, and to a certain extent, improve the service life of the cloth falling mechanism of the circular machine.

[0040] Specifically, in the embodiment, the cloth car lapping protrusion 230 is arranged at the end of the cloth box locking plate 200 away from the main frame 100, and the cloth car lapping protrusion 230 is used to connect with the cloth car.

[0041] Specifically, in the embodiment, the first support leg 240 and the second support leg 250 are connected to the cloth box locking plate 200, and the first support leg 240 and the second support leg 250 are both arranged at the middle part of the cloth box locking plate 200. Specifically, in the embodiment, the first support leg 240 and the second support leg 250 are hingedly connected to the cloth box locking plate 200, so that when the cloth box locking plate 200 is flipped upward and closes the placing entrance, the first support leg 240 and the second support leg 250 can be rotated downward relative to the cloth box locking plate 200 due to their own gravity, so as to automatically store the first support leg 240 and the second support leg 250, thereby avoiding collision with passing workers due to the extension of the first support leg 240 and the second support leg 250.

[0042] Specifically, the length of the first support leg 240 is less than the length of the second support leg 250. When the ground contact inclined surface 220 contacts the ground, the first support leg 240 is used to provide support for the middle part of the cloth box locking plate 200, thereby avoiding bending of the middle part of the cloth box locking plate 200 due to excessive weight of the cloth roll. When the cloth car lapping protrusion 230 contacts the cloth car, the second support leg 250 provides support for the middle part of the cloth box locking plate 200, thereby avoiding bending of the middle part of the cloth box locking plate 200 due to excessive weight of the cloth roll. In this way, the service life of the cloth falling mechanism of the circular machine is improved.

[0043] The locking device 300 is used to lock the cloth box locking plate 200, so that the cloth box locking plate 200 remains closed to the placing entrance.

[0044] Specifically, the locking device 300 comprises a locking protrusion 310 and a locking swing rod 320, in the embodiment, the locking protrusion 310 is fixedly arranged on the cloth box locking plate 200, the locking swing rod 320 is rotatably connected with the side stop 120 of the main frame 100, the locking swing rod 320 is provided with a locking slot 321, the locking slot 321 is lockedly connected with the locking protrusion 310. When the cloth box locking plate 200 is in the vertical state, the locking swing rod 320 is rotated, the locking protrusion 310 passes through the opening of the locking slot 321 and enters the locking slot 321, and then the locking of the cloth box locking plate 200 is completed.

[0045] In other embodiments, the locking device 300 can also be arranged as a combination of a conventional locking pin and a locking slot, and those skilled in the art can select the specific structure of the locking device 300 according to actual needs.

[0046] The preferred embodiments of the present application are described above, but the present application is not limited to the above-mentioned embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
