DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0029] As shown in the drawings, Figure 1 A point bead machine feeding mechanism includes a feeding frame 1. The feeding frame 1 serves as a bearing component to stably support and connect various components, thereby enabling the point bead machine feeding mechanism to achieve stable feeding.

[0030] In the embodiments of the present application, a feeding disc 2 and a feeding matching mechanism 3 are arranged on the feeding frame 1. The feeding matching mechanism 3 is used to place the material in the feeding disc 2, thereby achieving orderly distribution of the material. It should be noted that a plurality of arrayed storage cavities 21 are arranged on the feeding disc 2. The storage cavities 21 can be set to a shape suitable for the shape, specification and demand of the material, which will not be described here. The feeding matching mechanism 3 has the effect of conveying and feeding nuts, fragrant particles and exploding bead additives, and of course other individual shapes that are suitable for use with the point bead machine feeding mechanism of the present application, which will not be described here.

[0031] As shown in the drawings, Figure 1 , Figure 2As shown, the feeding cooperation mechanism 3 is provided with a hopper 31, at least one single-arm feeding pipe 321 and a connecting pipe 311 for guiding the material in the hopper 31 into the corresponding single-arm feeding pipe 321. In order to improve the efficiency, the single-arm feeding pipe 321 in the embodiment of the application is provided with 8, and has the effect of synchronously moving the 8 single-arm feeding pipes 321 along the horizontal direction to run and respectively perform the corresponding vertical lifting movement of the material feeding. Among them, the bottom of the single-arm feeding pipe 321 is provided for the material to pass through, and the single-arm feeding pipe 321 is connected with a gas injection unit 35 that injects gas inwardly and drives the material to accelerate through the bottom of the single-arm feeding pipe 321. Therefore, by guiding the material into the single-arm feeding pipe 321, and then combining the effect of the gas injection unit 35 to drive the material to accelerate and move, the feeding efficiency of the feeding mechanism of the bead machine at this point can be significantly improved.

[0032] It should be noted that in order to realize stable and high-precision feeding of the material, a visual detection module for identifying the position information of the material in the receiving cavity 21 and the feeding cooperation mechanism 3 is arranged on the feeding rack 1. Therefore, the feeding cooperation mechanism 3 guides the material in the feeding cooperation mechanism 3 into the corresponding receiving cavity 21 of the feeding disc 2 according to the detection information of the visual detection module.

[0033] As shown in Figure 1 、 Figure 2 , a transmission chain 11 is arranged on the upper side of the feeding rack 1. The transmission chain 11 is used to support and drive the feeding disc 2 to move laterally. The rear side of the single-arm feeding pipe 321 is fixedly connected with a lifting single-arm 32, and the lifting single-arm 32 is slidingly connected with a horizontal moving back plate 33 along the vertical direction. Among them, the horizontal moving back plate 33 is provided with an internal tooth transmission belt 331 and a motor 332 for driving the internal tooth transmission belt 331 to rotate. At the same time, the lifting single-arm 32 is detachably connected with a rack 322 engaged with the internal tooth transmission belt 331. Therefore, when the internal tooth transmission belt 331 is driven to run, the rack 322 will be driven to synchronously lift and run, and in turn achieve the purpose of driving the corresponding lifting single-arm 32 to run.

[0034] As shown in Figure 5As shown, a horizontal conveying mechanism 4 is provided between the loading rack 1 and the horizontal moving back plate 33. The horizontal conveying mechanism 4 is equipped with a stabilizing moving plate 41. A transverse sliding block 42 is provided on the lower side of the stabilizing moving plate 41, and a longitudinal sliding block 43 is provided on the upper side of the stabilizing moving plate 41. Correspondingly, the loading rack 1 is equipped with a transverse sliding rail 12 that matches the transverse sliding block 42, and the horizontal moving back plate 33 is equipped with a longitudinal sliding rail that matches the longitudinal sliding block 43. As a driving connection structure, the horizontal conveying mechanism 4 is equipped with two drag chains 44, one for driving the stabilizing moving plate 41 to slide along the transverse sliding rail 12, and the other for driving the horizontal moving back plate 33 to slide along the longitudinal sliding rail. Therefore, based on the combination of the drag chains 44 and the corresponding sliding rails and blocks, the stable driving of the loading mechanism 3 is achieved, thereby improving the loading efficiency and accuracy.

[0035] It is worth mentioning that, such as Figure 3 , Figure 4 As shown, a discharge hole matching the corresponding connecting material pipe 311 is provided on the lower side of the hopper 31. The discharge hole is used to sequentially guide the material filled in the hopper 31 into the corresponding single-arm feeding pipe 321. A perforated plate 341 and a linear telescoping device 34 for driving the perforated plate 341 to match or separate from the discharge hole and then match with the connecting material pipe 311 are provided on the lower side of the discharge hole. The linear telescoping device 34 adopts a cylinder, hydraulic cylinder or linear threaded screw connection structure, which will not be described in detail here. The jet unit 35 is used to blow air into the connecting material pipe 311 and blow the material into the feeding tray 2 when the perforated plate 341 matches the discharge hole. The jet airflow and pressure of the jet unit 35 are adjustable, so as to push the material with corresponding particle size and weight, so that the material falls accurately and efficiently into the corresponding receiving cavity 21.

[0036] To prevent material from being unable to pass through the discharge holes and thus affecting the material feeding efficiency, a lever 312 that rotates back and forth is installed inside the hopper 31. Simultaneously, a paddle 3121 for swinging back and forth is installed on the outside of the lever 312. Therefore, by driving the lever 312 to rotate the paddle 3121, the material inside the hopper 31 can be agitated, allowing the material to enter the corresponding discharge holes in an orderly manner. Furthermore, the material passes through the perforated plate 341 and, as the perforated plate 341 moves to match the connecting material pipe 311, is guided into the single-arm feeding pipe 321.

[0037] To sum up, the point bead machine feeding mechanism provided in the application realizes the effects of efficient and accurate material feeding by allowing the material to enter the single-arm feeding pipe 321 through the material bin 31 and then blowing the material into the feeding disc 2 by the air jet unit 35. At the same time, the point bead machine feeding mechanism provided in the application realizes accurate and effective monitoring of the material by the visual detection module, thereby improving the cooperation precision and stability between the feeding cooperation mechanism 3 and the feeding disc 2, and further improving the material feeding efficiency. The motor 332 drives the inner tooth transmission belt 331 to rotate when in operation, thereby driving the rack 322 to move vertically upward or downward along the operation of the inner tooth transmission belt 331, so as to realize the effects of stably driving the single-arm feeding pipe 321 to move and completing the material feeding. In the initial stage of the material feeding, the material is first filled in the material bin 31, and then the perforated plate 341 is driven by the linear extender 34, so that when the perforated plate 341 matches the discharging hole, the material located in the discharging hole falls into the perforation, and when the perforated plate 341 matches the connecting material pipe 311, the material located in the perforated plate 341 falls into the connecting material pipe 311 to be introduced into the single-arm feeding pipe 321, and then the air jet unit 35 is inflated into the single-arm feeding pipe 321 to achieve the effect of air flow pushing the material to quickly separate from the single-arm feeding pipe 321 to enter the corresponding storage cavity 21, so that the point bead machine feeding mechanism has the purpose of significantly improving the feeding efficiency and accuracy.
