Compared with the prior art, the application has the beneficial effects that:
the first pressing member is provided with a groove on a surface opposite to the second pressing member, and the surface opposite to the first pressing member on the second pressing member is horizontal, and when the first pressing member and the second pressing member are brought into abutting contact, the groove and the horizontal surface together form a notch for passing the self-seal. The notches may also be formed when the grooves are located in the second extrusion member, or both the first extrusion member and the second extrusion member have grooves.
The first movable arm and the second movable arm move to drive the first extrusion part and the second extrusion part to be separated, a larger gap is reserved for conveniently placing the grain film, and the self-sealing strip on the grain film is placed at the groove in a superposition mode. And then the first extrusion part and the second extrusion part are closed, and the self-sealing strips are compacted and inlaid together, so that the splicing combination of grain films is realized. The folded extrusion structure is pulled, and the two grain films can be continuously extruded and spliced until the splicing of the two grain films is completed. The grain film is flattened and flattened by the parts of the first extrusion part and the second extrusion part, which are not provided with grooves, so that wrinkles are avoided. Because the notch is arranged between the first extrusion part and the second extrusion part, the self-sealing strip of the grain film cannot be damaged due to overlarge extrusion.
Since the self-sealing strip needs to be pressed together, the first extrusion part and the second extrusion part have certain pressure on the grain film, so that the self-sealing strip has larger friction force when being pulled. The first extrusion part and the second extrusion part are rollers, the sliding friction force is changed into rolling friction force, the resistance is reduced, the grain film splicing and pressing device is pulled more easily and conveniently, and meanwhile the grain film is not easily scratched.
Grooves are formed in the peripheral surfaces of the first roller and the second roller, so that the center of a notch formed when the two rollers are folded is positioned on the same plane with the grain film, the stretching effect on the grain film in the splicing and pressing process is reduced, and the grain film is not easy to deform and damage.
The first movable arm and the second movable arm are hinged through a pin shaft to form two lever structures taking the pin shaft as a fulcrum. When the handle is operated, a person applies force to the handle, and the lever structure is used for transmitting the operation to the extrusion part without directly operating on the extrusion part, so that the handle is easier to use.
The first extrusion part is located above the second extrusion part, and the first handle is located above the second handle, namely the first movable arm and the second movable arm are only in contact at the pin shaft and are not intersected, so that when the first handle and the second handle are close, the first movable arm and the second movable arm rotate by taking the pin shaft as a fulcrum, and the first extrusion part and the second extrusion part are far away from each other. If the first pressing part is located above the second pressing part and the first handle is located below the second handle, namely, the first movable arm and the second movable arm intersect at the pin shaft to form a structure similar to scissors, when the first handle and the second handle are close, the first pressing part and the second pressing part are also close.
Because the torsion spring is sleeved on the pin shaft, the first movable arm and the second movable arm always have a folding trend through the acting force of the torsion spring, so that the operation performed on the handle corresponds to the separation of the two extrusion parts, and the grain film is conveniently placed in the handle. Based on the physiological structure of the human body, the two handles are more easily closed by finger holding than the two handles are far away by opening the fingers. Therefore, the first movable arm and the second movable arm are only in contact at the pin shaft and have no crossed connection structure, the handles are held to separate the extrusion parts, the handles are released after the grain film is put in the extrusion parts, the extrusion parts are tightly attached together by means of the acting force of the torsion spring, and extrusion embedding of the self-sealing strip is achieved.
The setting position of grain membrane is very close to the grain face, and the hand-held grain membrane splice compression fittings only can creeping forward when removing, has restricted the speed of removal. When the first extrusion part and the second extrusion part are folded, the first traction hole and the second traction hole are overlapped, at the moment, an external pull rope or pull rod can penetrate into the traction hole, and an operator can efficiently finish grain film splicing by pulling the pull rope or the pull rod along the direction of the self-sealing strip.
Set up guide structure before extrusion structure, two grain membranes insert respectively in first spout and the second spout, extend orbital guide through the spout and fold and place together, send into extrusion structure with the grain membrane that will fold again and extrude, the process of pulling grain membrane concatenation compression fittings is lighter, and the grain membrane also aligns the overlapping more easily, has guaranteed the accuracy of pressfitting.
When the first extrusion part and the second extrusion part are separated and used for placing the grain film, one side of the first movable arm close to the first extrusion part and one side of the second movable arm close to the second extrusion part are relatively far away. The first movable arm is provided with the guide plate, and when the movable arm is opened, the guide plate moves along with the movable arm, so that the distance between the guide plate and the opposite side wall is increased, and the grain film is easier to be placed in the chute; when the movable arms are folded, the guide plate returns to the original position, so that the chute keeps the original size, and the grain film can be stably guided without shaking. The positioning block is arranged on the second movable arm, so that the width of the cross section of the second chute is limited, and the grain film placed in the second chute can be guided and limited more stably. Install the deflector on the first movable arm and will pull the hole and install on the second movable arm through the screw, can be according to the thickness of the grain membrane of pressfitting concatenation to dismouting replacement to make grain membrane concatenation compression fittings be applicable to the grain membrane of different thickness different specifications.
When the grain film is placed in the chute, the self-sealing strip can be just placed in the guide groove and is not extruded by the side wall of the chute; the self-sealing strip is limited through the guide groove, so that the grain film can be better guided and positioned, and the grain film can be accurately overlapped together.
