Description

Technical Field

[0001] This utility model belongs to the field of polymer production technology, specifically relating to an auxiliary handle for adjusting a tool holder. Background Technology

[0002] Plastic filament drawing machines utilize polypropylene and high-density ethylene as raw materials. Through heating, extrusion, slitting, and stretching, flat filaments are formed, which are then wound up for weaving on circular looms. During the production process of plastic filament drawing machines, the lower position of the blade holder needs to be adjusted to improve the uniformity of filament splitting. Currently, when adjusting the blade holder, operators must work within a narrow 15cm gap below the blade holder, which is quite difficult. Without suitable tools, the adjustment typically takes 8-12 hours. Utility Model Content

Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the tool holder adjustment auxiliary handle structure of this utility model. Detailed Implementation

[0019] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] This embodiment proposes a tool holder adjustment auxiliary handle, the structure of which is as follows: Figure 1 As shown, it mainly includes a long bolt 1, an extension rod 2, a fastening nut 3, and a rotating handle 4. Among them, the long bolt 1 is an M16 bolt, the extension rod 2 is welded to the top of the head of the long bolt 1, and the fastening nut 3 is welded to the top of the extension rod 2. The fastening nut 3 is an M22 nut.

[0021] Two symmetrically arranged rotating handles 4 are welded onto the shaft of the long bolt 1. The rotating handles 4 are made of M8 steel bars.

[0022] In this embodiment, the length between the bottom of the long bolt 1 and the top of the fastening nut 3 is 200mm, and the length of each rotating handle 4 is 100mm, which is set at 60° to the bottom of the long bolt 1.

[0023] When using the tool holder adjustment auxiliary handle, the bottom thread of the long bolt 1 is screwed into the threaded hole on the tool holder base, and the fastening nut 3 is pressed against the tool holder body from below. During the production process of the plastic wire drawing machine, the tool holder normally generates 0.3MPa air pressure. When the tool holder needs to be adjusted, the operator holds the two rotating handles 4 and rotates them by hand. By adjusting the screw length of the bottom thread of the long bolt 1 into the threaded hole on the tool holder base, the position of the tool holder body is directly adjusted by the fastening nut 3, avoiding the use of ordinary wrenches to adjust the tool holder.

[0024] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
