Description

Technical Field

[0001] The present invention relates to a frame device, and more particularly to a frame device for a packing machine. Background Art

[0002] A packing machine is a machine that binds items with packing belts. The frame device is a motion guiding and supporting device for the packing belts before binding items. There is a frame device that adopts a structure combining a movable frame and a fixed frame. The original side transmission structure of the movable frame adopts a processing method of a whole piece of part, generally a whole piece of nylon plate, which is inconvenient to process and has a high cost. Since the frame of the packing belt has a certain height and the movable frame moves at a high speed and high frequency, the side transmission structure is prone to deformation. Moreover, according to the different needs of different customers, the height dimension of the packing machine frame may also change, which will in turn cause the side transmission components in the height direction to need to be redesigned and manufactured, affecting mass production and standardized production. All these bring no small trouble to the manufacturers and users. Summary of the Invention

[0003] The purpose of the present invention is to provide a novel frame device to solve the problems in the background art, and the transmission components in the height direction of the frame device can reduce deformation and improve compatibility. To this end, the present invention adopts the following technical solutions:

[0004] A frame device, comprising a fixed frame and a movable frame, the movable frame is arranged facing the fixed frame and can move back and forth in the direction towards the fixed frame and away from the fixed frame; a transmission mechanism is arranged on the side of the frame device, and the transmission mechanism is provided with a transmission rod; characterized in that the transmission rod comprises an upper standard part, a lower standard part and an intermediate connecting rod, and the upper standard part and the lower standard part are respectively connected to the upper and lower ends of the intermediate connecting rod; the upper standard part and the lower standard part are respectively provided with an inclined guiding and driving structure for driving the movable frame to move horizontally, and a vertical guiding limiting groove is arranged on the transmission rod.

[0005] Further, the inclined guiding and driving structure is an inclined guiding limiting groove whose width is just adapted to the outer diameter of the roller on the movable frame to prevent the roller shaft from being distorted.

[0006] Further, the vertical guiding limiting groove of the transmission rod is arranged in the upper standard part and the lower standard part.

[0007] Further, the transmission mechanisms are respectively arranged on the first side and the second side of the frame device, and each side of the transmission mechanism is provided with the transmission rod, and the transmission rod comprises the upper standard part, the lower standard part and the intermediate connecting rod.

[0008] Further, the transmission mechanisms are respectively arranged on the first side edge and the second side edge of the frame device. The transmission rods are arranged on each side of the transmission mechanism. The transmission rod on the first side includes a first upper standard part, a first lower standard part and a first intermediate connecting rod. The transmission rod on the second side includes a second upper standard part, a second lower standard part and a second intermediate connecting rod. The first upper standard part is further provided with a first shaft hole, and the first shaft hole is connected to the connecting rod between the transmission mechanism on the first side edge and the upper horizontal connecting rod of the frame device. The first lower standard part is further provided with a second shaft hole, and the second shaft hole is connected to the movable frame opening and closing transmission link structure between the movement and the transmission mechanism on the first side edge. The second upper standard part is further provided with a third shaft hole, and the third shaft hole is connected to the connecting rod between the transmission mechanism on the second side edge and the upper horizontal connecting rod of the frame device.

[0009] Further, both ends of the intermediate connecting rod are clamping heads, and clamping grooves adapted to the clamping heads are respectively arranged on the upper standard part and the lower standard part.

[0010] A guide plate matched with the transmission rod is arranged on the side edge of the fixed frame. Upper horizontal guide grooves and lower horizontal guide grooves respectively matched with the inclined guide transmission structures on the upper standard part and the lower standard part are arranged on the guide plate. Rollers coaxially matched with the inclined guide transmission structure of the upper standard part and rollers matched with the upper horizontal guide groove are arranged on the upper part of the side edge of the movable frame. Rollers coaxially matched with the inclined guide transmission structure of the lower standard part and rollers matched with the lower horizontal guide groove are arranged on the lower part of the side edge of the movable frame.

[0011] In the present invention, the previous integral transmission rod is divided into upper and lower standard parts and an intermediate connecting rod which are combined and connected. It is easy to process. And when facing different sizes, only the length of the intermediate connecting rod needs to be changed to adapt, so that the standard parts can achieve universal batch production. Moreover, the sizes of the upper and lower standard parts are small and not easy to deform. The intermediate connecting rod can be made of a material with better rigid strength under certain conditions, which can also prevent deformation and increase the service life. At the same time, the overall transmission rod is lighter, and the opening and closing actions are smoother and more stable. Further, the inclined guide transmission structure can be made into an inclined guide limiting groove, so that the roller shaft is uniformly stressed and will not deform, making the frame opening and closing work more stable.
