Description

Technical Field

[0001] This utility model relates to the field of raw material tape stretching, and in particular to a raw material tape stretching machine. Background Technology

[0002] An existing patent (publication number: CN103434129B) discloses a raw material tape stretching machine. The heating device first heats the material in a heating chamber, then it enters a second heating chamber for further heating. During this second heating, the film is stretched by an stretching roller. Finally, the film exits the heating chamber and is wound up by a winding device. During winding, a sensor detects the film on the winding shaft. However, this device, which has "a winding guide roller and a winding shaft on the winding frame," relies on the winding shaft at the rear of the drum to collect the stretched raw material tape. If the winding shaft needs to be replaced after winding during the winding process, it may not be able to temporarily fix and cut the raw material tape, which has certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of the existing technology by providing a raw material stretching machine that guides the raw material stretching chamber body output by two sets of guide wheels at the front of the first cutting table. When it is necessary to replace the locating pin after winding, the lower clamping plate is raised by two sets of clamping plate cylinders at the front of the clamping plate table, so that the upper and lower clamping plates clamp the raw material stretching on both sides of the cutting blade. In conjunction with the blade holder cylinder, the cutting blade is raised and lowered, so that the cutting blade cuts the stretched raw material stretching. After cutting, the raw material stretching inside the upper and lower clamping plates near the locating pin is released, so that the locating pin can be replaced separately after winding, thereby increasing the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0008] 1. During the use of this utility model raw material strip stretching machine, the raw material strip output from the raw material strip stretching chamber is guided by two sets of guide wheels at the front of the first cutting table. When it is necessary to replace the locating pin after winding, the lower clamping plate is lifted by two sets of clamping plate cylinders at the front of the clamping plate table, so that the upper clamping plate and the lower clamping plate clamp the raw material strip on both sides of the cutting blade. In conjunction with the blade holder cylinder, the cutting blade is driven to rise and fall, so that the cutting blade cuts the stretched raw material strip. After cutting, the raw material strip inside the upper and lower clamping plates near the locating pin is released, so that the locating pin can be replaced separately after winding, thereby increasing the adaptability of the equipment.

[0009] 2. During the use of this utility model raw material tape stretching machine, after the raw material tape is cut by the cutting blade driven by the blade holder cylinder, the bolts on the side of the take-up wheel clamp are removed to detach the take-up wheel clamp from the central shaft, and the positioning pin on the side of the central shaft is pulled out, so that the positioning pin can be removed from the equipment for replacement, thereby facilitating the quick replacement of the positioning pin by the staff.

[0010] 3. During the use of this utility model raw material strip stretching machine, the two ends of the raw material strip are clamped by two sets of upper and lower clamping plates. After the raw material strip is cut by the cutting blade driven by the blade holder cylinder, the screw is rotated by the screw motor at the front of the screw table. The screw moves the clamping plate table and moves the cut raw material strip out of the cutting blade range for disassembly and replacement. This avoids the operator's hands from entering the cutting blade range, thereby increasing the safety of the equipment. Attached Figure Description
