Embroidery of the embroidery machine is a high-speed movement process, and a presser foot and a needle bar generally move in a straight line and are not easy to damage, but a presser foot transmission device and a needle bar transmission device of a machine head of the embroidery machine are a transmission process and need a cam and a transmission mechanism to realize, so the cam and the transmission mechanism are easy-damage parts and need frequent maintenance, particularly the cam; therefore, the problem of conveniently dismounting the cam and the transmission mechanism needs to be considered when designing the structure inside the machine head of the embroidery machine. Patent No. 2017202172961 discloses a presser foot driving device for an embroidery machine head, the driving device is arranged outside a cam, and two driving shafts in the driving device are arranged on a side plate and a head shell; when the cam and the transmission device need to be repaired, the cam and the transmission device need to be detached one by one, which is extremely inconvenient.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a presser foot transmission of embroidery machine aircraft nose convenient to dismouting, it is inboard that cam is located to its transmission, and transmission's transmission shaft installs in same curb plate for make things convenient for cam and presser foot transmission of dismouting and maintenance embroidery machine aircraft nose.
In order to achieve the above object, the utility model provides a following technical scheme:
a presser foot transmission device of an embroidery machine head convenient to disassemble and assemble comprises a machine shell, a cam, a transmission device, a presser foot device, a needle bar frame and a needle bar; the cam is driven by the main shaft and is arranged in the shell; the transmission device comprises a first transmission rod, a connecting rod and a second transmission rod which are connected in sequence; the track groove on the inner side of the cam is connected with the end rolling body of the first transmission rod in a matching way; the end part of the second transmission rod is matched with a presser foot device, and the presser foot device is matched and connected with a needle rod arranged on a needle rod frame and is pressed tightly by a spring on the needle rod; the first transmission shaft of the first transmission rod and the second transmission shaft of the second connecting rod are arranged on the side plate of the machine shell, and the side plate is arranged below the cam and does not interfere with the transverse disassembly and assembly of the cam along the main shaft.
The first transmission rod is in a V shape with an opening at 110 degrees to the left, and the second transmission rod is in a V shape with an opening at 110 degrees to the upper.
The torque ratio of the first transmission rod to the second transmission rod is 1.2: 1, the acting force of the track groove on the inner side of the cam and the rolling body can be reduced, thereby reducing the abrasion.
The transmission device is arranged at the inner side of the cam, and the side plate is arranged below the cam, so that the cam of the quick-wear part is convenient to disassemble and maintain; and the first transmission shaft and the second transmission shaft of the transmission device are integrated with the side plate of the casing, so that the side plate and the transmission device are convenient to integrally disassemble and maintain.
