Detailed Description

The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.

Examples

Referring to fig. 1 to 5, the structure of the ramie binder of the present embodiment includes an upper ramie binder member 1 and a lower ramie binder member 2.

The upper hemp-clamping component 1 of the embodiment comprises an upper hemp-clamping plate 3, the lower hemp-clamping component 2 comprises a lower hemp-clamping plate 4 and a screw rod 5, wherein the upper hemp-clamping plate 3 and the lower hemp-clamping plate 4 are both made of elastic metal plates, the upper hemp-clamping plate 3 is an arc plate with the middle concave and the two ends raised, the lower hemp-clamping plate 4 is a flat plate, and the screw rod 5 is symmetrically arranged at the left end and the right end of the lower hemp-clamping plate 4. In the structure of the existing ramie clamping device, because the screw rod is positioned at the central position of the ramie clamping device, the upper ramie clamping plate 3 is usually designed to be a structure with a convex center, so that after the screw rod applies force to press the upper ramie clamping plate 3 downwards, the upper ramie clamping plate 3 can gradually deform to be horizontal, thereby ensuring that the ramie bundles at each position on the ramie clamping device are basically uniformly stressed, and similarly, after the screw rod 5 is moved to the left end and the right end of the lower ramie clamping plate 4 in the embodiment, the stress of the upper ramie clamping plate 4 is changed from the central position to two ends, so that the two ends of the upper ramie clamping plate 4 are tilted, the upper ramie clamping plate 4 can gradually tend to be horizontal after the two ends are stressed, the uniform stress of the ramie bundles at each position is ensured, if the upper ramie clamping plate 4 is a flat plate, the middle part of the upper ramie clamping plate 4 is easy to arch upwards after the two ends are stressed, so that the ramie bundles at the position can not be. After the screw rod 5 is moved to the two ends, positioning pins which are originally positioned at the two ends of the hemp clamping device and have the positioning function can be omitted, and the structure of the device is simplified.

Four guide posts 6 are arranged on the upper surface of the upper hemp clamping plate 3, the guide posts 6 are respectively positioned at four angular positions of the upper hemp clamping plate 3, the guide posts 6 are cylinders, and the top of the guide posts is semicircular. The guide post 6 can provide a stress supporting point when the ramie holder moves, so that the direct force applied to the ramie holding plate when the ramie holder moves is avoided, the damage to the ramie bundle caused by overlarge stress on the ramie holding plate is prevented, and the guide post 6 can also control the moving track of the ramie holder to enable the ramie holder to move forwards along a preset route.

The upper and lower both ends of pressing from both sides numb board 3 of this embodiment are equipped with circular shape boss 7, and the center of boss 7 is equipped with through-hole 8, and the screw rod 5 is installed to the corresponding position that presss from both sides numb board 4 down, and wherein, through-hole 8 is the big, the little bell mouth in top in bottom, and the upper end of screw rod 5 is conical to process through the chamfer. After the upper hemp-clamping plate 3 and the lower hemp-clamping plate 4 are aligned, the screw rod 5 needs to penetrate through the through hole 8, so that the relative movement of the upper plate and the lower plate is limited, the upper ends of the through hole 8 and the screw rod 5 are designed to be conical, the positioning of the through hole 8 and the upper end of the screw rod 5 can be facilitated, and the screw rod 5 can be more easily sleeved into the through hole 8.

Two rubber belts 10 are all installed to the bottom surface that presss from both sides fiber crops board 3 on this embodiment and the top surface that presss from both sides fiber crops board 4 down, and rubber belt 10 plays sealed and cushioning effect when the device presss from both sides tightly, can not only avoid pressing from both sides fiber crops board 3 and press from both sides fiber crops board 4's metal covering direct contact down, and reducing wear can reduce moreover because of the too big problem production that causes the fiber crops to crush of pressure. The peripheries of the upper hemp-clamping plate 3 and the lower hemp-clamping plate 4 are all subjected to chamfering treatment, so that an operator is prevented from being scratched by a sharp part during working.

The bottom of the screw rod 5 of this embodiment is welded on the lower hemp-clamping plate 4, after the upper hemp-clamping plate 3 and the lower hemp-clamping plate 4 are matched in place, the screw cap 11 sleeved on the screw rod 5 is used for clamping, the screw cap 11 is in threaded engagement with the thread section 9 of the screw rod 5, downward pressure is applied to the upper hemp-clamping plate 3, the upper hemp-clamping plate 3 deforms after being stressed and gradually tends to be in a horizontal state, so that a hemp bundle placed between the upper hemp-clamping plate 3 and the lower hemp-clamping plate 4 is clamped tightly, and the screw rod 5 is welded on the lower hemp-clamping plate 4, so that the clamping effect is prevented from being influenced by the fact that the screw rod 5 rotates together with the screw cap 11 when the screw cap.

In addition, it should be noted that the specific embodiments described in the present specification may be different in the components, the shapes of the components, the names of the components, and the like, and the above description is only an example of the structure of the present invention. All the equivalent changes or simple changes made according to the structure, characteristics and principle of the utility model are included in the protection scope of the utility model.
