[0028] Embodiments

[0029] As shown in Figures 1-4 The present application provides a technical scheme: the blanking conveying belt 2 is the main conveying channel of the nut, which is horizontally laid on the top of the fixed chassis 1 and can carry a large number of nuts and realize continuous and stable linear motion by relying on its own transmission device.

[0030] The limiting seats 3 on the front and back sides are in the form of long strips and have a certain height, and are respectively installed at the two side edge positions of the conveying belt. By means of physical blocking, the nuts are limited from deviating to both sides during the conveying process, so as to ensure that the nuts always move within the specified range of the conveying belt and prevent the nuts from falling or deviating from the predetermined conveying route, thereby laying a foundation for subsequent accurate material distribution and conveying.

[0031] The guide seat 4 of the auxiliary conveying assembly is installed above the blank conveying belt 2, and the mounting groove 5 opened in the interior of the guide seat 4 provides a stable mounting space for the two rolling wheels 7. The two rolling wheels 7 are arranged in parallel and can freely rotate in the mounting groove 5. The guide belt 6 is formed into a closed loop structure by being wound around the two rolling wheels 7.

[0032] The driving motor 8 connected to the top of one of the rolling wheels 7 provides a power source for the entire auxiliary conveying assembly. When the driving motor 8 is started, the output shaft of the driving motor 8 drives the rolling wheel 7 connected thereto to rotate. Due to the friction between the guide belt 6 and the rolling wheel 7, the guide belt 6 is synchronously rotated.

[0033] In the process of the nut being conveyed forward along with the blank conveying belt 2, the rotating guide belt 6 contacts the nut and generates a friction force. By reasonably adjusting the rotating speed and direction of the guide belt 6, the nut can be pushed to enter the material distribution assembly in an orderly manner in a predetermined direction, so as to effectively avoid the nut from being jammed at the joint between the blank conveying belt 2 and the material distribution assembly, and ensure the continuity and efficiency of the entire blanking process.

[0034] The principle is to use the friction force generated by the motor driving the belt movement to guide the nut movement, and the limiting seat 3 laterally restricts the position of the nut, which cooperates to ensure the stability of batch conveying of the nut.

[0035] The mounting frame 9 of the material distribution assembly is firmly fixed at the corresponding position of the equipment. The servo motor 10 at the bottom of the mounting frame 9 is a core power component and is tightly connected with the rotating shaft 11 through a shaft coupling.

[0036] After receiving the control signal, the servo motor 10 accurately controls the rotating angle, speed and direction of the rotating shaft 11 according to the preset program and parameters. The material distribution disc 12 connected to the top of the rotating shaft 11 is a circular planar structure, and the edge thereof is designed with a groove or a protrusion structure matched with the outer shape of the nut for accommodating and positioning the nut.

[0037] The two guide limiting members 13 are respectively installed on the front and back sides of the material distribution disc 12 and are fixedly connected with the limiting seat 3 of the blank conveying belt 2, forming a continuous guide channel to ensure that the nut is smoothly transferred from the blank conveying belt 2 to the material distribution disc 12 without deviation.

[0038] The limiting and blocking bottom disc 14 located at the bottom of the material distribution disc 12 is disc-shaped and is fixed with the assembly seat 15 of the assembly line conveying belt. The main function of the limiting and blocking bottom disc 14 is to block the nut from falling from the bottom during the rotation of the material distribution disc 12 and to provide stable support for the material distribution disc 12. The servo motor 10 drives the material distribution disc 12 to rotate slowly. During the rotation, the nuts on the blank conveying belt 2 are sequentially accommodated into the accommodating structure of the material distribution disc 12. With the rotation of the material distribution disc 12, the nuts are sequentially arranged and conveyed to the assembly line conveying belt under the constraint of the guide limiting members 13.

[0039] The principle is to use the precise control characteristics of the servo motor 10, combined with the structure design of the distribution disc 12 and the guide limiting part 13, to realize the single arrangement and accurate transportation of the nut, improve the accuracy and stability of the nut transportation, and provide good material preparation for the subsequent processing procedures.

[0040] The collection box 19 is placed in a suitable position of the equipment and kept stable as the final collection container of the debris, and the adsorption pipe 18 connected to the top thereof is a hollow pipe structure for conducting airflow and debris.

[0041] The adsorption seat 17 at the top of the adsorption pipe 18 is designed to be adapted to the shape of the bottom of the assembly line conveying belt mounting seat 15, ensuring that the two are tightly connected and well sealed, so that the adsorption seat 17 can cover a certain area of the assembly line conveying belt body 16.

[0042] The negative pressure pump 20 connected to the left side of the adsorption pipe 18 is the power core of the entire dust collection assembly. When the negative pressure pump 20 is started, a negative pressure environment is formed inside the adsorption pipe 18 and the adsorption seat 17. The several uniformly opened notches on the assembly line conveying belt body 16 provide a channel for the suction of debris. During the transportation of the nut by the assembly line conveying belt body 16, due to the suction force generated by the negative pressure pump 20, the debris on the surface of the nut and around it due to processing is driven by the pressure difference and is sucked into the adsorption seat 17 through the notches, and then enters the collection box 19 along the adsorption pipe 18.

[0043] Among them, the communication structure design of the adsorption seat 17 and the bottom of the assembly line conveying belt mounting seat 15 and the reasonable layout of the notches ensure that the debris can be sucked away to the maximum extent without affecting the normal transportation of the nut. The principle is to use the pressure difference created by the negative pressure pump 20 to make the debris flow from the high-pressure area (around the nut) to the low-pressure area (collection box 19) under the driving of air flow, thereby realizing effective collection of the debris and avoiding its flying and spreading in the workshop.

[0044] In summary, in use, the nut is placed on the feeding conveying belt 2 and moves forward with the running of the feeding conveying belt 2 under the lateral constraint of the limiting seat 3. When the nut reaches the auxiliary transportation assembly position, the driving motor 8 drives the guide belt 6 to rotate, and the guide belt 6 pushes the nut to smoothly enter the distribution disc 12 of the distribution assembly.

[0045] The distribution disc 12 is slowly rotated under the drive of the servo motor 10, and the nut is arranged and transported one by one to the assembly line conveying belt under the synergistic action of the guide limiting part 13.

[0046] During the transportation of the nut along the pipeline conveying belt, the negative pressure pump 20 of the negative pressure suction assembly is started, a negative pressure is formed in the suction seat 17 and the suction pipe 18, the nut surface and the surrounding debris are sucked into the collecting box 19 through the slot on the pipeline conveying belt body 16, the whole working process of the nut feeding, distributing, transporting and debris cleaning is completed, and the efficient, stable and environment-friendly nut machining feeding process is realized.

[0047] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
