[0033] The present utility model provides a power transmission mechanism for transmitting power to a moving device on a ring conveyor line.

[0034] In this embodiment, referring to Figures 1-5 , the power transmission mechanism for transmitting power to a moving device on a ring conveyor line includes a ring bracket, a ring conveyor mechanism, and a mold tray 7. The mold tray moves in a circular motion along the outer circle of the ring bracket under the conveyance of the ring conveyor mechanism, and further includes:

[0035] A reciprocating track 20, which is arranged along the length direction of the ring bracket;

[0036] A reciprocating seat 16, which is movably engaged with the reciprocating track, and the reciprocating seat can reciprocate along the reciprocating track under the action of an external force. A circular tube seat 10 is fixedly connected to the wire hole of the reciprocating seat, the mold tray is connected to the circular tube seat, and a fixed seat 27 is arranged at the bottom of the reciprocating seat, and a trolley collector 25 is arranged on the fixed seat 27;

[0037] The carbon brush box 15, the carbon brush box and the reciprocating seat are rotationally matched through a bearing block 14 and a bearing 17, and the bearing block is of a hollow structure;

[0038] The carbon brush current collector 12, the carbon brush current collector is rotationally connected to the bearing block 14 through a motor slip ring 13, and the bearing block is of a hollow structure;

[0039] The sliding contact wire 24, the sliding contact wire is fixed on the reciprocating track, and the sliding contact wire current collector takes power by sliding on the sliding contact wire;

[0040] The drag chain 19, the drag chain is fixedly connected to the mold tray;

[0041] The sliding contact wire current collector is electrically connected to the carbon brush current collector through a wire 32, and the carbon brush current collector is electrically connected to the drag chain on the tray through a wire 33.

[0042] At present, the conventional ring conveyor mainly includes a ring bracket, a ring conveying mechanism and a mold tray. The ring bracket is composed of a head frame 1, a bracket 2 and a tail frame 3 spliced together. The ring conveying mechanism includes a motor, a speed reducer, a driving sprocket 21, a driven sprocket 23 and a chain 5 connecting the driving sprocket 21 and the driven sprocket 23. A plurality of mold trays 7 are installed on the chain 5 through bolts, and the mold tray 7 can move in a ring along the chain path. This structure belongs to the existing conventional structure and will not be described in detail here.

[0043] The specific power taking principle is as follows: The sliding contact wire is connected to an external power supply, the sliding contact wire is charged, so that the sliding contact wire current collector slidingly connected to the sliding contact wire is charged. The wire connected to the sliding contact wire current collector passes through the hollow bearing block and the carbon brush current collector, and the wire connected to the carbon brush current collector passes through the hollow circular tube seat and is connected to the drag chain. The drag chain 19 is in a ring shape and is fixed behind the mold tray 7 by a buckle 28, and moves in a ring together with the mold tray 7. The electric wire can be connected to the distribution box 29 on a plurality of mold trays 7 through the drag chain 19 to provide power for the devices (the heating plate in the tray) in the tray moving on the conveyor line (note: the device can be a mold that needs to provide electric heating).

[0044] Specifically, a roller bracket is provided on the outer ring of the ring bracket, rollers are installed on the roller bracket, and the mold tray is in rolling fit with the rollers.

[0045] The addition of the roller bracket and rollers on the outer ring of the ring bracket enables the mold tray to move smoothly along the ring path, reduces the frictional resistance, and improves the operating efficiency of the overall system.

[0046] Specifically, the mold tray and the circular tube seat are connected through an adaptive adjustment mechanism.

[0047] The adaptive adjustment mechanism makes the connection between the mold tray and the round tube seat more flexible, capable of automatically compensating for displacements caused by manufacturing or installation errors, enhancing the stability of the entire power transmission mechanism. It improves the adaptability of the system to different working environments, especially showing better performance when facing complex and changeable working conditions.

[0048] Specifically, the adaptive adjustment mechanism includes a guide seat 11 fixedly connected to the mold tray and a guide plate 9 connected to the guide seat through a slide rail-slider assembly 6, and the guide plate 9 is connected to the round tube seat through a linear bearing 8.

[0049] The guide seat and the guide plate are connected by a slide rail-slider assembly and used in conjunction with a linear bearing, which can automatically compensate for displacements caused by manufacturing or installation errors, enhancing the stability of the entire power transmission mechanism.

[0050] Specifically, connecting plates are provided on both sides of the reciprocating seat, double-row bearings are provided on the connecting plates, and the reciprocating track is slidably arranged between the double-row bearings.

[0051] The design of the double-row bearings on both sides of the reciprocating seat provides additional support points, ensuring the smooth sliding of the reciprocating seat on the track while also enhancing its structural strength.

[0052] Specifically, the trolley wire is fixed to the reciprocating track through a support bar 26.

[0053] The support bar is used to fix the trolley wire to the reciprocating track, ensuring the accurate position of the trolley wire and preventing deviation caused by vibration or other external forces.

[0054] Specifically, limit seats 18 are provided at both ends of the reciprocating track, and both ends of the trolley wire are fixed to the limit seats.

[0055] The limit seats provided at both ends of the reciprocating track can effectively limit the stroke range of the reciprocating seat, avoiding the situation of accidentally disengaging from the track.

[0056] Specifically, wiring grooves 30 are provided on the limit seats, and the power connection wires 31 at both ends of the trolley wire extend out from the wiring grooves.

[0057] Setting the wiring grooves on the limit seats facilitates the arrangement and management of the wires at the ends of the trolley wire, simplifying the installation process of the electrical circuit.

[0058] Specifically, a heating plate is provided at the bottom of each mold tray, and the heating plate is electrically connected to the drag chain through a distribution box 29.

[0059] After adopting the above solution, each mold tray can independently turn on or off the heating function, enabling flexible adjustment of the heating state according to actual needs during the production process and improving the flexibility of operation. When a certain mold tray does not require heating, its heating power supply can be separately turned off through the control system, avoiding unnecessary energy waste, thus effectively reducing the overall energy consumption and contributing to the goal of energy conservation and emission reduction.

[0060] Generally speaking, the characteristics of this design lie in providing safe and stable power transmission for the device in motion. There is a fastening relationship between the mold tray 7 and the guide seat 11. The reciprocating track 20 is installed on the H-shaped bracket 4. When the tray 7 moves, the slider on both sides of the guide plate 9 drives the carbon brush box 15 to move synchronously with the linear bearing 8. Since the linear bearing 8 is adopted to increase the stress area of the round tube seat 10, even if the carbon brush box 15 and the reciprocating box 16 can rotate at any time, the smoothness of the carbon brush box during movement is still ensured. When the tray 7 with the guide seat 11 enters the semi-circular track of the head frame 1, the mold tray 7 and the reciprocating seat 16 stop linear movement. The tray 7 makes a semi-circular movement with the driving sprocket 21 as the center and gives a force in the rotation direction to the carbon brush box 15 through the guide plate 9 to drive the carbon brush box 15 to rotate. After completing the rotation, it still continues to move linearly, and the same applies to the tail frame. To solve the inevitable error problem of the frame equipment during the production process, the slide rail and slider assembly 6 is added to solve the height error between the carbon brush box 15 and the guide seat 11 during synchronous movement, and the linear bearing 8 is added to solve the horizontal spacing error between the carbon brush box 15 and the guide seat 11, realizing the stability of power transmission in circular motion.

[0061] All technicians should note that although this utility model has been described according to the above specific implementation manners, the idea of this utility model is not limited to this utility model alone. Any modification using the idea of this utility model will be included in the scope of protection of this patent right.
