Description

Technical Field

[0001] The invention relates to the field of wire binding equipment, in particular to a multi-hole threading binding machine. Background Art

[0002] The wire binding machine is a binding tool for binding printed documents, personnel files, files, financial vouchers, etc. into books. The advantages and disadvantages of the existing binding machines are:

[0003] One is a multi-hole movable wire binding machine. Currently, most of this type of machine can only perform single-wire binding. The so-called double-wire binding means that one side has one hole, two holes are double-wire, and two to three holes are double-wire; on the other side, one hole to two holes is single-wire, and two holes to three holes are single-wire. This binding structure does not meet the national archive binding requirements.

[0004] The second is a three-hole punching and threading machine, which punches three holes at a time. After punching, the single wire is lifted up by a thread-lifting needle, and then when the wire passes through the hole, the two ends of the wire are manually threaded into the wire ring in the middle hole and tied.

[0005] The above two machines provide poor user experience during use. The thread-pulling needle is prone to fall off during the thread-pulling and thread-pulling processes, and the prices are relatively high.

[0006] In addition, most enterprises and institutions are already equipped with various types of punching machines, such as single-hole, two-hole, and three-hole punching machines.

[0048] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will, with reference to the accompanying drawings of the embodiments of the present invention, Figures 1-14 clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are some, rather than all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention fall within the scope of protection of the present invention.

[0049] As Figures 1-11 shown: A porous thread-binding machine, the porous thread-binding machine 100 includes a support mechanism 110. The support mechanism includes a support substrate 111. Side support plates 112 are provided on both sides of the support substrate. A workbench plate 113 is fixedly provided at the top ends of the two side support plates 112. A first needle-passing slot hole 115 and a cardboard-pressing through hole 116 are provided on the workbench plate 113 along the width direction, and a first wire-releasing slot 117 is correspondingly provided on the workbench plate 113 and corresponding to the first needle-passing slot hole.

[0050] Among them, as Figures 6-11 shown, two rows of guiding elastic support components 160 are arranged in parallel between the support substrate 111 and the workbench plate 113. The guiding elastic support components 160 include two guiding rods 05. A guiding shaft sleeve 03 and a limiting shaft sleeve 04 are fixedly sleeved on the guiding rods 05. The limiting shaft sleeve 04 is fixedly connected to the guiding rod through positioning screws provided on its circumference. The guiding shaft sleeve is fixedly provided at the lower end of the support connecting plate. The position of the limiting shaft sleeve on the guiding rod is adjustable; A support connecting plate 02 that presses against the limiting shaft sleeve 04 is sleeved on the two guiding rods 05. A compression spring 01 that presses against the support connecting plate 02 and the workbench plate 113 is sleeved on the guiding rod; The support connecting plate can overcome the elastic force of the compression spring thereon, so as to realize the lifting movement of the support connecting plate along the guiding rod; It should be noted that the positional relationship between the compression spring, the support connecting rod, and the workbench plate is not specific. For example, the compression spring can be arranged on the lower side of the support connecting plate, and the same technical effect can also be achieved by applying a force to the support connecting plate to overcome its traction force;

[0051] Among them, as Figures 1-4As shown, a cardboard pressing plate 130 is fixedly arranged on the supporting connecting plate of a row of guiding elastic supporting components at the rear side of the supporting substrate 111. The cardboard pressing plate 130 includes a pressing plate 131 and a longitudinal connecting plate 133 perpendicular to the pressing plate. The lower end of the longitudinal connecting plate 133 is inserted through the cardboard pressing plate through hole 116 and fixedly connected to the supporting connecting plate. A second needle passing slot hole 132 is correspondingly arranged on the pressing plate 131 at a position corresponding to the first needle passing slot hole 115. During the ascending process of the supporting connecting plate, it can drive the cardboard pressing plate to ascend, so that a working gap is formed between the cardboard pressing plate and the workbench plate. At this time, a book spine can be pushed into the working gap along the workbench plate, and then the jacking of the supporting connecting plate is released. The cardboard pressing plate can be reset downward under the action of the compression spring and pressed tightly on the book spine.

[0052] Among them, as Figures 1-9 shown, a thread topping needle assembly 140 is fixedly arranged on the supporting connecting plate of a row of guiding elastic supporting components at the front side of the supporting substrate 111. The thread topping needle assembly 140 includes a thread topping needle mounting plate 142 perpendicular to the supporting connecting plate. The needle mounting plate and the supporting connecting plate can be fixedly connected by screws.

The thread topping needle supports can be automatically slidably connected along the mounting long hole and are fixedly connected to the needle mounting plate through fixing nuts 144. A thread topping needle 141 is vertically arranged on the thread topping needle support. The thread topping needle 141 can successively pass through the first needle passing slot hole 115 and the second needle passing slot hole 132 as the supporting connecting plate ascends. The thread topping needle 141 includes a needle body 1411. A second wire releasing groove 1413 is arranged at the upper end of the needle body 1411. At both sides of the second wire releasing groove at the upper end of the needle body 1411, a thread topping needle tip 1414 and a secondary thread topping needle tip 1412 are respectively formed. The thread topping needle can conveniently and efficiently clamp the binding thread into the second wire releasing groove, and as the thread topping needle ascends, the binding thread can be passed through the binding holes of the book to be bound, and then the two ends of the thread are manually passed through the middle hole wire loop and tied to complete the binding. A second scale 06 is arranged at the front side of the supporting connecting plate 02 connected to the thread topping needle assembly 140. This kind of thread topping needle assembly can conveniently and accurately adjust the position on the thread topping needle mounting plate, and the distance between adjacent two thread topping needle assemblies can be adjusted, thus greatly improving the applicability of the multi-hole thread-passing binding machine.
