When the film frame needs to be turned over and converted, the outer spherical ball bearing can be inwards compressed to the left side of the positioning rib, so that the limitation on the film frame is unlocked.

As shown in fig. 12-14, each set of positioning device comprises a positioning hydraulic cylinder 411, a shaft sleeve 412, and a positioning shaft 413, one end of the positioning shaft is connected with the positioning hydraulic cylinder, the other end of the positioning shaft is hinged with a T-shaped head 414 through a hinge shaft 415, the T-shaped head 414 comprises a straight end 4141, and a first inclined shoulder 4142 and a second inclined shoulder 4143 are symmetrically arranged on two sides of the straight end 4141. The shaft sleeve 412 is coaxially sleeved outside the positioning shaft 413, the shaft sleeve 412 is further provided with a rotation preventing shaft 416, the positioning shaft 413 is further provided with a positioning groove 4131, and the rotation preventing shaft 416 penetrates through the positioning groove 4131. Thus, under the pushing of the positioning hydraulic cylinder 411, the positioning shaft 413 can only do telescopic motion along the axial direction thereof, and is limited by the rotation preventing shaft 416, the positioning shaft 413 cannot rotate around the axis thereof, so that the T-shaped head cannot rotate around the axis of the positioning shaft, and the T-shaped head can only do telescopic translation or rotate in the axis plane of the hinge shaft. After the T-shaped head is stressed to rotate around the hinge shaft, and after the external force is removed, in order to enable the T-shaped head to automatically reset to the middle balance state, that is, the upper surface of the straight end 4141 is in the horizontal state, the positioning device is further provided with a balance maintaining device, the balance maintaining device can be a torsion spring arranged on the hinge shaft, or an upper tension spring 417 and a lower tension spring 417 as shown in fig. 12, the left ends of the upper tension spring and the lower tension spring are respectively connected with the backs of the two oblique shoulders, and the right ends of the upper tension spring and the lower tension spring are respectively connected with the two ends of the rotation preventing shaft.

When the film frame needs to be transposed and turned over, the positioning hydraulic cylinder pushes the positioning shaft to drive the T-shaped head to extend out in advance to be in a waiting state, then the winding disc drives the film frame to rotate, so that the outer spherical ball bearing on the film frame is contacted with the straight end on the T-shaped head and is pressed tightly, the T-shaped head rotates, the first inclined shoulder or the second inclined shoulder inwards extrudes the outer spherical ball bearing, the outer spherical ball bearing is contracted to the inner side of the positioning flange, the outer spherical ball bearing can smoothly enter the turning track arc edge position at the moment, the outer spherical ball bearing rolls to another clamping position under the driving of the rotating power of the winding disc, the spring pops the outer spherical ball bearing out at the moment, and the positioning flange at the other side clamps the outer spherical ball bearing to position the film frame. Specifically, when the membrane frame is reversed and transposed, the outer spherical ball bearing 5023 on the rotating membrane frame 500 touches the straight end 4141 of the extended T-shaped head, and as the T-shaped head 414 is hinged on the hydraulic positioning shaft 413, the T-shaped head 414 rotates around the hinge shaft 415, one of the inclined shoulder surfaces presses the outer spherical ball bearing 5023 and compresses the spring 5034, and the rotation by 90 degrees is performed by the power provided by the rotation around the frame; when the winding frame rotates reversely, the other oblique shoulder face of the T-shaped head can reset the film frame by 90 degrees in reverse rotation, and the positioning clamping groove is arranged on the positioning shaft, so that the T-shaped head cannot rotate and deflect, and can automatically reset to a middle balance state under the action of the positioning tension spring, thereby ensuring the stable position state and reliable action of the positioning device.

In order to realize the overturning positioning of the film frame, another positioning mode can be adopted, a U-shaped clamping block is directly and fixedly connected to a positioning shaft of a positioning device, and the U-shaped clamping block can realize the overturning of the film frame only after the U-shaped clamping block needs to accurately hold an outer spherical surface ball bearing of a limiting device. The U-shaped fixture block and the T-shaped head in the U-shaped fixture block can achieve reversing positioning effect on the membrane frame, but the U-shaped fixture block has strict requirements on an electric control system, a sensor system, a hydraulic system and the like in work, and an outer spherical ball bearing on the membrane frame can not be caught when a rotation error is large, so that the transposition is out of control; and the requirement greatly reduced of this patent's T type head structure to automatically controlled hydraulic pressure part, at the rotatory in-process of winding the frame, as long as the pneumatic cylinder action stretches out the location axle before the membrane frame is changeed in place, the straight end of T type head will block the insert ball bearing of membrane frame, takes place the upset action then. Therefore, the device has low requirement on the positioning precision of the film frame, and the T-shaped head does not need to be accurately aligned to the outer spherical surface ball bearing, but the T-shaped head extends out in advance to wait, so that the error in the positioning of the film frame is effectively reduced, and the reliability of the transposition and overturning action of the film frame is improved. Although the membrane frame does not have a driving device, the membrane frame in the device is smoothly turned and positioned through ingenious structural design.

When the film frame is in a horizontal state, the winding disc rotates to drive the film frame to synchronously rotate, and the film winding on the film roll can perform horizontal film winding operation on four surfaces of a cuboid material block in the center of the winding disc; after the left and right film frames 500 are switched to vertical state at the same time, as shown in fig. 15, the winding disc is not moved, so that the rectangular material block 600 on the turntable 800 rotates in the horizontal plane, and thus the vertical film winding operation can be performed on the two end surfaces of the rectangular material block; in order to promote vertical film winding sealing effect, still can be through the small-angle beat of coiling, the upper and lower small-angle motion of membrane frame about the drive, make left and right membrane frame be in the state of high left and low right, low left and high right in proper order, all make the material piece several circles in horizontal plane internal rotation under every state, thereby it also obtains comprehensive encapsulation with the upper and lower bight of cuboid material piece to thin with the plastic film, accomplish the winding to six faces of cuboid silage piece, consequently, this device has the winding frame rotation flexibility and stability, the membrane frame is reliable and smooth advantage of upset location immediately, twine membrane convenient operation swiftly, good to the leakproofness of material piece, be favorable to the fermentation of silage piece.
