Description

Technical Field

[0001] This utility model relates to the field of measuring equipment, and in particular to a coat hanger type die head bolt length measuring tool. Background Technology

[0002] Coat hanger-type dies are key equipment in plastic extrusion molding, especially in the manufacture of lithium battery separators, where they play a fundamental molding role. Their working principle involves uniformly extruding molten polyolefin raw materials through internal channels to form a cast sheet with micron-level thickness precision. This cast sheet then undergoes precise processes such as biaxial stretching, solvent extraction, and heat setting to ultimately form the separator product that determines battery safety. The uniformity of the internal channel clearance of the die (typically requiring ±0.5μm / m) directly determines the consistency of the cast sheet thickness, and the length tolerance of the die bolts is the core parameter for controlling the channel clearance.

[0003] Currently, the measurement of the length of the die head bolts mainly relies on traditional measuring tools (such as vernier calipers and depth gauges), which has three major technical bottlenecks: the two ends of the bolts are irregular curved surfaces (such as ball head / counterhead structures), and the flat probes of traditional measuring tools cannot stably meet them, making it easy to tilt during measurement and resulting in an error of ±0.1mm; the installation space for bolts inside the die head is narrow (usually ≤50mm wide), and standard measuring tools cannot be positioned vertically, requiring repeated disassembly and assembly of bolts, with each measurement taking more than 10 minutes; the diaphragm production line needs to adjust 200 to 400 bolts at the same time, and the accumulation of manual measurement errors will lead to amplification of the flow channel gap deviation.

[0004] In view of the above problems, there is an urgent need for a device to solve them. Utility Model Content

[0033] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0034] like Figures 1 to 4 As shown in the figure, the present invention provides a coat hanger type mold head bolt length measuring tool, which includes a measuring ruler 100 and a sliding measuring device 200. The sliding measuring device 200 is disposed on the measuring ruler 100 and slides on the measuring ruler 100 so that the sliding measuring device 200 measures the length of the coat hanger type mold head bolt.

[0035] Its specific structure includes:

[0036] A first measuring scale portion 120 and a second measuring scale portion 130 are provided on the measuring scale 100. The first measuring scale portion 120 and the second measuring scale portion 130 together form a measuring scale 100. The first measuring scale portion 120 and the second measuring scale portion 130 are arranged opposite to each other. A scale is linearly arranged on both the first measuring scale portion 120 and the second measuring scale portion 130 to facilitate the measurement of the length of the object. At the same time, a groove 140 is formed between the first measuring scale portion 120 and the second measuring scale portion 130. The groove 140 extends along the direction of the scale.

[0037] In this embodiment, the sliding measuring device 200 is mounted on the measuring ruler 100 via the slide groove 140. More specifically, the sliding measuring device 200 is disposed on the first measuring ruler portion 120 and is limited on the first measuring ruler portion 120 via the slide groove 140. The sliding measuring device 200 includes a sliding plate 220, a limiting member 240, and a sliding member 230. The limiting member 240 and the sliding member 230 are respectively disposed at both ends of the sliding plate 220. The sliding plate 220 is disposed on the upper surface of the measuring ruler 100, and one end of the sliding plate 220 abuts against the slide groove 140. The sliding member 230 is located within the slide groove 140, so that the sliding plate 220 can move on the first measuring ruler portion 120 by moving the sliding member 230 within the slide groove 140.

[0038] Since the slider 230 and the limiting member 240 are respectively located at both ends of the slider 230, a limiting groove 250 is formed between the slider 230 and the limiting member 240. The first measuring part 120 on the measuring ruler 100 is located in the limiting groove 250, so that the slider 230 can slide on the first measuring part 120 through the limiting groove 250.

[0039] The slide plate 220 moves on the first measuring scale 120 to measure the length of the bolt. This length measurement is performed using the pressing member 210 and the abutment member 110. Specifically, the abutment member 110 is located on the 0 mark at one end of the measuring scale 100, and the pressing member 210 is located on the slide plate 220 on the side corresponding to the abutment member 110. The movement of the slide plate 220 on the first measuring scale 120 can drive the pressing member 210 to move relative to the abutment member 110. When the bolt is located between the abutment member 110 and the pressing member 210, the slide plate 220 is moved so that the slide plate 220 moves along the position of the first measuring scale 120, thereby causing the pressing member 210 on the slide plate 220 to press the bolt. When the bolt is pressed by the abutment member 110 and the pressing member 210, the corresponding scale mark on the pressing member 210 is the overall length of the bolt.

[0040] In this embodiment, both the abutment 110 and the pressing member 210 are configured as magnetic adsorption members to facilitate the fixing of bolts and to facilitate measurement.

[0041] Meanwhile, preferably, the magnetic adsorption component is configured as an embedded permanent magnet, and the magnetic adsorption surfaces of the abutment 110 and the extrusion 210 match the shape of the end of the die bolt to ensure that the abutment 110 and the extrusion 210 can be stably adsorbed at both ends of the die bolt, thereby improving the accuracy and stability of the measurement. Furthermore, the embedded permanent magnet design makes the abutment 110 and the extrusion 210 less prone to falling off or being damaged during use, further ensuring the reliability and durability of the measuring tool. During the measurement process, the user only needs to adsorb the abutment 110 and the extrusion 210 onto both ends of the die bolt respectively, and then slide the sliding measuring device 200 to easily read the length of the bolt, greatly improving measurement efficiency and accuracy.

[0042] In this embodiment of the application, to facilitate accurate measurement of the bolts, a certain degree of stability needs to be provided for the movement of the slide plate 220 when it is moved. Specifically:

[0043] A first abutting surface 121 is formed on one side of the first measuring portion 120 corresponding to the position of the slide groove 140, and a second abutting surface 131 is formed on one side of the second measuring portion 130 corresponding to the position of the slide groove 140. The first abutting surface 121 is provided corresponding to the second abutting surface 131, and in this embodiment, the height of the second abutting surface 131 is higher than the height of the first abutting surface 121.

[0044] Since the slider 230 is located in the slide groove 140, in order to facilitate the sliding of the slide plate 220 on the first measuring part 120, a third abutting surface 231 is provided on the slider 230 at the position corresponding to the first abutting surface 121, and the third abutting surface 231 abuts against the first abutting surface 121.

[0045] To prevent the slider 230 from falling off the first measuring section 120, a fixing groove 122 is provided in the slide groove 140. The fixing groove 122 is provided along the setting direction of the slide groove 140, specifically, the fixing groove 122 is located below the first abutment surface 121. The slider 230 is provided with a fixing member 232 corresponding to the position of the fixing groove 122. One end of the fixing member 232 is located in the fixing groove 122, and the fixing member 232 can move within the fixing groove 122. Through the setting of the fixing member 232 and the fixing groove 122, the slider 230 can be prevented from falling off the slide groove 140, making the slide plate 220 more stable when sliding on the first measuring section 120. A locking member 260 is provided on the slide plate 220 at a position corresponding to the second abutment surface 131. One end of the locking member 260 abuts against the second abutment surface 131. The locking member 260 can lock the position of the slide plate 220 on the first measuring part 120 to prevent the slide plate 220 from sliding on the first measuring part 120, thereby enabling accurate measurement of the bolt length.

[0046] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
