Detailed Description

The automatic stringing machine consists of main mechanism and lower frame, the bedplate and the upper part are the main mechanism, and the lower frame is the part below the bedplate.

The chain transmission mechanism below the middle is a feeding chain group 20, and the template fixed on the chain of the group is called a feeding mold 23. The feeding chain set 20 is used for conveying the strung material, accommodating and positioning the strung material, guiding the bamboo sticks and the cutter 97.

The side chain transmission mechanism is a cutter chain group which is specifically divided into a left cutter chain group 40 and a right cutter chain group 50, and the templates fixed on the cutter chain group are called cutter dies which are specifically divided into a left cutter die 43 and a right cutter die 53. The cutter chain group is used for conveying the bamboo sticks, positioning and guiding the bamboo sticks; and to feed and feed the cutter 97, house and guide the cutter 97.

The chain transmission mechanism above the middle is a pressing chain group 30, and a template fixed on the chain is called a pressing die 33. The chain pressing group 30 is used for pressing and positioning the string material; and a guide bamboo stick and cutter 97.

In addition, a special label supply group 60 is arranged above the knife chain group. The supply unit 60 receives and arranges the bamboo sticks, and supplies the bamboo sticks to the cutter chain unit orderly and automatically.

The three sets of chain transmission mechanisms and the label supply set 60 run synchronously to drive the supply die 23, the cutting die and the pressing die 33 to convey, contain, position and guide so as to smoothly complete the insertion of the bamboo labels and the cutting-off action of the string materials.

Throughout the process, the bamboo stick and cutter 97 must be guided between the die 23, the cutting die and the pressing die 33. To ensure such guidance, the relative positions of the three templates must be calibrated and maintained simultaneously, otherwise subsequent actions may be affected.

If the accuracy of the relative positions of the three templates cannot be guaranteed, problems arise during the label insertion process. Specifically, label missing, label breakage, and label sticking may occur. More seriously, the bamboo stick can damage other parts of the equipment after being stuck. Likewise, problems can occur during the cutting of the strand by the cutter 97. In particular, blade leakage and blade sticking may occur. The consequences caused by tool leakage and tool jamming are also very serious, the tool 97 can be seriously deformed under the action of external force, and related parts can be damaged more seriously, so that chain reaction is brought.

Therefore, the embodiment ensures the accuracy of the relative positions among the feeding die 23, the cutting die and the pressing die 33, completes the accurate guiding of the bamboo sticks through the guiding group, and comprehensively ensures the stability and the rapidity of the operation of the whole equipment.

The inserting pair means that the aligning pins are inserted into the corresponding aligning holes and align different molds.
