Description

Technical Field

[0001] This utility model relates to the bead feeding mechanism of a bead feeding device. Background Technology

[0002] The bead feeding device is used to transport beads. The bead discharging mechanism of the bead feeding device is used to transfer the beads in the barrel from the positioned guide rod downwards to the corresponding position on the bead feeding plate.

[0003] The existing bead-setting mechanism includes a guide rod, a mounting frame, and at least two sets of clamps arranged sequentially on the mounting frame to hold and position the guide rod. A drive shaft is mounted on the mounting frame, and corresponding actuating arms located on the drive shaft at corresponding positions on the clamps engage with a clamping arm of each clamp to drive the sequentially arranged clamps to open and close alternately. The actuating arms are typically mounted on the drive shaft with screws for positioning. Because the sequentially arranged clamps need to open sequentially, the actuating arms on the drive shaft need to be set at specific angles to ensure precise timing of opening of the corresponding clamps as the drive shaft rotates, and to ensure that at least one set of clamps is holding the guide rod at all times. This presents significant challenges to manufacturing, installation, and debugging. Firstly, high manufacturing precision is required, and secondly, high assembly precision is needed during product assembly and debugging, placing high demands on assembly and debugging personnel and the assembly environment.

[0004] Currently, fixing the actuating arm and drive shaft with screws has several drawbacks. Screws can loosen, gaps can form between the drive shaft and the actuating arm, and with the use of ball bearing mechanisms, the fit between the drive shaft and the actuating arm will gradually decrease, further increasing the difficulty of installing and adjusting the actuating arm. Summary of the Invention

[0005] This invention addresses the problems of high manufacturing costs and inconvenient installation and debugging of the drive rod of the existing bead feeding device's bead arranging mechanism by providing a bead arranging mechanism that is easy to manufacture and simplify debugging.

[0006] The technical solution of this utility model to solve the existing problems is: a bead arranging mechanism, including a bead guide rod, a mounting frame, at least two sets of clamps arranged sequentially on the mounting frame to hold the positioning guide rod, a drive shaft set on the mounting frame, a drive motor driving the drive shaft to rotate, and a lever arm on the drive shaft located at the corresponding position of the corresponding set of clamps to control the opening and closing of the corresponding set of clamps in a time-sharing manner. The drive shaft and the lever arm are integrally set, and the lever arm controlling the opening and closing of the corresponding set of clamps in a time-sharing manner satisfies that at least one set of clamps always holds the positioning guide rod.

[0007] As a further improvement, the actuating arm is provided with a roller that cooperates with the corresponding clamping arm of the clamp.

[0008] As a further improvement, each set of clamps includes a pair of cooperating clamping arms, with cooperating meshing teeth between the pair of clamping arms, and one clamping arm of the pair of clamping arms is provided with a drive arm that cooperates with a corresponding actuating arm on the drive shaft.

[0009] As a further improvement, the mounting bracket is provided with a protruding mounting block for mounting the clamp, the drive shaft is located inside the mounting bracket, and the mounting bracket is provided with a through groove for accommodating the clamping arm and / or drive arm of the clamp.

[0010] As a further improvement, the mounting block and mounting bracket are integrated into one unit.

[0011] As a further improvement, the clamp is provided with a mounting shaft that mates with the mounting groove, and the mounting block is provided with a mounting groove for mounting the clamp drive arm.

[0012] As a further improvement, the mounting groove is an arc-shaped opening groove with an outer opening that mates with the mounting shaft, the inner wall of the mounting groove is provided with a connecting hole, and the mounting shaft is provided with a connecting bolt that connects to the connecting hole.

[0013] As a further improvement, the drive shaft is integrated with the crankshaft of the toggle arm.

[0014] As a further improvement, the upper end of the drive shaft constitutes a cylinder drive shaft for driving the cylinder to rotate and thread the beads.

[0015] As a further improvement, the drive motor is located at the bottom of the mounting bracket.

[0016] Compared with existing technologies, this utility model includes a guide bead rod, a mounting frame, at least two sets of clamps arranged sequentially on the mounting frame to hold and position the guide bead rod, a drive shaft mounted on the mounting frame, a drive motor that drives the drive shaft to rotate, and a lever arm on the drive shaft located at the corresponding position of the clamp in each set to control the opening and closing of the corresponding clamp in a time-sharing manner. The drive shaft and lever arms are integrally designed, facilitating the precision machining of the corresponding lever arms on the drive shaft. Its advantages include high machining precision of the lever arms integrally designed with the drive shaft, high matching precision between the lever arms, effectively avoiding the need for installation and adjustment of the lever arms, preventing the accumulation of errors during use, and completely eliminating the need for later installation and adjustment. This utility model also features high precision and durability in driving the corresponding clamps with the drive shaft. Attached Figure Description

[0024] See Figure 1-9 This embodiment discloses a bead-arranging mechanism, including a bead guide rod 4, a mounting frame 1, at least two sets of clamps 2 arranged sequentially on the mounting frame 1 to hold and position the bead guide rod 4, a drive shaft 3 mounted on the mounting frame 1, and a drive motor 32 that drives the drive shaft 3 to rotate. A lever arm 31 for controlling the opening and closing of the corresponding set of clamps 2 is provided on the drive shaft 3 at the corresponding position of each set of clamps 2. The drive shaft 3 and the lever arm 31 are integrally formed, and the lever arm 31 is completely fixed to the drive shaft 3, allowing the lever arm 31 to precisely drive the opening and closing of the corresponding set of clamps. The upper end of the bead guide rod 4 of the bead-arranging mechanism can be used as a bead-threading end and inserted into a rotating material cylinder 5 41 for bead threading. The lower end of the bead guide rod 4 can be used to suspend above the bead-feeding clamp of the bead-feeding mechanism to facilitate the supply of beads to the bead-feeding mechanism. The time-sharing opening can be done by opening one by one alternately, or by any number of sets of clamps forming a large group, which alternately opens with any other set or any large group of clamps.

[0025] In practical use, the corresponding clamps can be driven by the return spring to maintain the clamping state, and the toggle arm 31 can only be used to open the clamps.

[0026] Typically, 3-6 sets of clamps are used. Referring to the attached diagram, in this embodiment, 4 sets of clamps are used, with the 4 sets of clamps 2 arranged sequentially from top to bottom to hold the positioning guide rod 4. The drive shaft 3 has 4 sets of actuating arms 31 integrated with it, corresponding to the 4 sets of clamps. Each of the 4 sets of actuating arms 31 cooperates with a corresponding clamp to control the clamps to open alternately at different times. However, it is necessary to ensure that at any given time, at least one set of clamps is holding the positioning guide rod 4, to prevent the guide rod 4 from losing its position when any clamps open alternately at different times.

[0027] To facilitate the engagement of the actuating arm 31 with the clamp 2, the actuating arm 31 is provided with a roller 21 that engages with the corresponding clamping arm of the clamp 2.

[0028] Each clamp 2 includes a pair of cooperating clamping arms 24. The pair of clamping arms 24 are used to clamp and position the guide bead rod 4, and a clamping jaw for clamping the guide bead rod 4 can be provided between the pair of clamping arms 24. The pair of clamping arms 24 are provided with cooperating meshing teeth so that the pair of clamping arms 24 can open and close synchronously. In order to facilitate the control of the pair of clamping arms by the actuating arm 31, one clamping arm of the pair of clamping arms 24 is provided with a driving arm 22 that cooperates with the corresponding actuating arm 31 on the drive shaft 3.

[0029] The actuating arm 31 can be configured as a protruding single arm or as a cam-shaped arm, which cooperates with the clamp 2 through the cam-shaped protrusion or the protruding single arm. The specific shape of the actuating arm 31 can be determined according to the actual situation.

[0030] The drive shaft 3 is an integral crankshaft with the actuating arm 31. The upper end of the drive shaft 3 forms the drive shaft 3 for rotating the material cylinder 5 to thread the beads. The drive motor 32 is located at the bottom of the mounting bracket 1. The drive shaft 3 is driven by a single motor, which in turn drives the clamp and the material cylinder 5.

[0031] In this utility model, the drive shaft 3 and the actuating arm 31 are integrated. The angle position of the actuating arm can be designed according to the process time of driving the corresponding number of clamps. (See [reference needed]). Figure 9 The actuating arms corresponding to different sets of clamps can be integrally cast first, and then the ends of the drive shaft 3 that need to be connected and positioned, as well as the corresponding actuating arms 31, can be precision machined. This effectively maintains the accuracy of the relative position and angle of the actuating arms 31 corresponding to the clamps on the drive shaft 3. The position between the different actuating arms 31 driving the corresponding clamps can be completely guaranteed through casting and subsequent precision machining. Since only the mating positions of the drive shaft and actuating arms need to be precision machined, which is a small number, the manufacturing process of the drive shaft can be greatly simplified, the cost can be reduced, and the accuracy of the actuating arms can be effectively improved. This avoids subsequent installation and debugging, greatly simplifies the installation and debugging process of the ball-arranging mechanism drive shaft, and requires no subsequent maintenance.

[0032] To further simplify the installation of the clamp, the mounting frame 1 is provided with a protruding mounting block 11 for mounting the clamp 2, the drive shaft 3 is located inside the mounting frame 1, and the mounting frame 1 is provided with a through groove for accommodating the clamping arm 24 and / or the drive arm 22 of the clamp 2.

[0033] The mounting block 11 is integrally formed with the mounting frame 1. The mounting block 11 can be precision machined in the mounting frame 1 to improve the accuracy of the mounting block 11.

[0034] To facilitate the installation of the clamp, the clamp 2 is provided with a mounting shaft 23 that mates with the mounting groove 12, and the mounting block 11 is provided with a mounting groove 12 for installing the drive arm 22 of the clamp 2. The corresponding clamping arm 24 is located on the other side of the mounting shaft 23 to form a drive arm.

[0035] The mounting groove 12 is an arc-shaped opening with an outer opening that mates with the mounting shaft 23. The inner wall of the mounting groove 12 is provided with a connecting hole, and the mounting shaft 23 is provided with a connecting bolt 25 that connects to the connecting hole. This allows for the clamp to be installed from the outside via the connecting bolt 25.
