Description

Technical Field

[0001] This utility model belongs to the technical field of small bar baling machine heads, and particularly relates to a transmission system for a small bar baling machine head. Background Technology

[0002] Foreign line packing machine heads mostly adopt a purely mechanical transmission structure, which requires a large number of precision-fitting parts. This results in a bulky overall structure of the equipment, high requirements for the machining accuracy of parts, and high assembly and maintenance costs.

[0003] In traditional baling machine systems, the wire feeding mechanism and the wire biting mechanism are often driven independently, requiring complex electrical structures for synchronous control. This can easily lead to a mismatch between the wire feeding length and the wire biting timing due to signal delays or mechanical wear, resulting in loose baling or wasted wire.

[0004] Traditional baling machine systems mostly use ordinary electromagnetic brakes, which have long braking times and are difficult to start and stop quickly at high speeds, resulting in excessively high wire feeding length errors and failing to meet the requirements of high-precision baling. In addition, due to the frequent start and stop of key components (such as clutches and brakes), traditional baling machine systems are prone to wear and tear. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a transmission system for a small bar wire packing machine head.

[0006] This small bar wire baling machine head uses a transmission system. The wire baling machine head includes an upper wire baler and a lower wire baler. The wire baling machine head is mounted on a base plate and includes: a main control servo motor, a reducer, a main drive gear, an electromagnetic clutch gear A, an electromagnetic clutch gear B, a main drive shaft, a shaft-mounted flange A, a shaft-mounted flange B, an electromagnetic clutch A, an electromagnetic clutch B, an electromagnetic brake A, an electromagnetic brake B, a wire feeding spool, a drive bevel gear A, a drive bevel gear B, a connecting rod shaft, a wire biting cylinder, and a cylinder tail.

[0007] A reducer mounting plate and a neutral plate are fixedly connected to the base plate. A mounting plate A is also fixedly connected to the base plate and the reducer mounting plate. A shaft-mounted flange A and a shaft-mounted flange B are installed on the neutral plate.

[0008] A speed reducer is fixedly mounted on a speed reducer mounting plate, and the speed reducer is fixedly connected to the main control servo motor. The speed reducer is also electrically connected to the main control servo motor. The speed reducer is coaxially connected to the main drive gear, which meshes with electromagnetic clutch gear A and electromagnetic clutch gear B. The main drive shaft of electromagnetic clutch gear A is coaxially connected to the wire guide wheel core, and the wire guide wheel core is sleeved with the wire feed spool. Electromagnetic clutch gear B is shaft-connected to drive bevel gear A, and drive bevel gear A meshes with drive bevel gear B. Electromagnetic clutch gear A is coaxially and fixedly connected to electromagnetic clutch A, and electromagnetic clutch gear B is coaxially and fixedly connected to electromagnetic clutch B. When the main drive gear rotates forward, it rotates clockwise; when the main drive gear rotates reverse, it rotates counterclockwise.

[0009] An electromagnetic brake A is also provided on the main drive shaft for connecting electromagnetic clutch gear A and electromagnetic clutch A, between electromagnetic clutch A and shaft-mounted flange A; similarly, an electromagnetic brake B is also provided on the main drive shaft for connecting electromagnetic clutch gear B and electromagnetic clutch B, between electromagnetic clutch B and shaft-mounted flange B.

[0010] A connecting rod shaft and a fixed plate B are fixedly mounted on a fixed plate A. A cylinder tail is fixedly mounted on a fixed plate B. A thread-biting cylinder is mounted on the cylinder tail and can rotate around the cylinder tail. The thread-biting cylinder is used to open or close the upper and lower thread channels.

[0011] A vertical connecting plate is sleeved on the connecting rod shaft, and the vertical connecting plate can rotate around the connecting rod shaft. The vertical connecting plate is fixedly connected to the wire-biting horizontal connecting plate, which is rotatably connected to the wire-biting cylinder. The wire-biting horizontal connecting plate is used to limit the wire feeding length.

[0012] Preferably, the reducer is fixed to the reducer mounting plate by shaft seal cover A and shaft seal cover B.

[0013] Preferably, the neutral plate is provided with an electromagnetic brake fixing plate A and an electromagnetic brake fixing plate B. The electromagnetic brake fixing plate A is used to fix the electromagnetic brake A, and the electromagnetic brake fixing plate B is used to fix the electromagnetic brake B.

[0014] The beneficial effects of this utility model are:

[0015] The core transmission chain of this utility model consists of a main control servo motor, a reducer, and a main transmission gear. It is equipped with an electromagnetic clutch gear as a drive, which reduces the number of transmission stages. Compared with the existing line packing machine head, it has reduced many parts. Key components can be quickly disassembled and assembled, shortening maintenance time.

[0016] The electromagnetic clutch and electromagnetic brake are arranged in a coordinated manner on the main drive shaft to achieve rapid braking response, reduce wire feeding length error, and meet the high-precision packaging requirements of bar stock.

[0017] The matching arrangement of the main drive gear and the drive bevel gear can ensure that the power source for the wire feeding and wire biting actions is unified, avoiding the signal delay caused by the independent drive in the traditional baling machine system;

[0018] The bite cylinder is mechanically connected to the connecting rod shaft, the vertical connecting plate and the bite horizontal connecting plate, so as to realize the mechanical synchronization of the bite action and the wire feeding length. This avoids the complex electrical control synchronization in the traditional baling machine system and eliminates defects such as loose baling or wire waste caused by signal delay or mechanical wear.

[0019] The integrated design of the electromagnetic clutch and brake reduces wear caused by frequent starts and stops. With the stable support of the neutral plate and the reducer mounting plate, the failures that occur during continuous operation of the equipment can be greatly reduced, and maintenance costs and downtime losses are also significantly reduced.
