Description

Technical Field

[0001] This utility model belongs to the field of spinning equipment, and specifically relates to an inner cover for a syringe. Background Technology

[0002] A yarn spraying machine is a device that loosens yarn into yarn slivers, then sprays the yarn slivers into a syringe. The syringe needle bar rotates under the rotation of a motor, turning the yarn slivers into hollow yarn. When the yarn is loosened into yarn slivers, some lint is generated. During the process of spraying the yarn slivers into the syringe, the lint is sprayed out along with the yarn slivers and falls into the syringe.

[0003] The aforementioned syringes typically have an inner cover installed inside. This inner cover rotates with the needle bar, allowing heavier slivers to fall into it and be spun into yarn via hooks on the needle bar. Lighter lint needs to be promptly discharged and cleaned to prevent excessive lint from affecting the normal operation of the syringe and the quality of the hollow yarn produced. However, in actual use, lint easily accumulates inside the syringe's inner cover, and the lint fibers entangled on the outer wall of the inner cover are also difficult to clean.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the general background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] This utility model improves upon the defects of the syringe inner cover described in the background art through the following technical solution.

[0006] The provided syringe inner cover has multiple elongated holes on the side of the inner cover shell. The elongated holes are vertically arranged and arranged circumferentially. The number of elongated holes corresponds to the number of hooks on the needle bar and is located next to the corresponding hooks. When the hooks are spinning, the lint can be thrown out of the inner cover in time through the elongated holes.

[0007] The upper inner wall of the shell is a smooth curved surface. Of course, the upper end of the inner shell is open. When the lint falls into the inner shell from above along with the lint strips, the lint will slide down along the smooth curved surface to the long hole and be thrown out of the inner shell. In this way, lint will not easily accumulate inside the shell.

[0008] The lower outer wall of the shell has a step. When too much lint fiber is wrapped around the outer wall of the inner shell, the worker can use a hook knife to move the lint to the step of the shell, and then use the hook knife to hold the step to cut the lint fiber, so as to easily clean away the wrapped lint fiber.

[0009] Furthermore, multiple protruding ribs are fixedly connected to the lower inner wall of the inner cover. The protruding ribs are vertically arranged and evenly distributed circumferentially. These protruding ribs are used for limiting the installation of the inner cover and the needle bar. Multiple needle grooves are opened on the outer wall of the needle bar. When the lower part of the inner cover is fitted onto the needle bar, its protruding ribs can be located in the empty needle grooves of the needle bar for limiting, so that the inner cover can rotate with the needle bar. This installation and limiting method facilitates the disassembly and cleaning of the inner cover.

[0010] Preferably, the thickness of the protruding ridge is 0.3 mm. When there is no empty needle groove on the needle bar, the protruding ridge of this thickness can also be confined within the needle groove without affecting the setting of the hook.

[0011] Through the above technical solutions, this utility model has at least the following beneficial effects:

[0012] In the syringe described in this application, when lint falls into the inner casing of the inner casing from above along with the lint strips, the lint will slide down along the smooth curved inner wall of the casing to the elongated hole, and thus be thrown out of the inner casing. In this way, lint will not easily accumulate inside the inner casing. When too much lint fiber is wrapped around the outer wall of the inner casing, the worker can use a hook knife to push the lint to the step of the casing, and then use the hook knife to hold the step to cut the lint fiber, thereby making it easy to clean away the wrapped lint fiber.

[0018] refer to Figure 1 and Figure 2 An inner cover for a syringe has multiple elongated holes 2 on the side of the inner cover housing 1. The elongated holes 2 are vertically arranged and arranged circumferentially. The number of elongated holes 2 corresponds to the number of hooks on the needle bar and is located next to the corresponding hooks. When the hooks are spinning, the lint can be thrown out of the inner cover in time from the elongated holes 2.

[0019] The upper inner wall of the shell 1 is a smooth curved surface 3. Of course, the upper end of the shell 1 of the inner cover is open. When the lint falls into the shell 1 of the inner cover from above with the lint strips, the lint will slide down along the smooth curved surface 3 to the long hole 2 and be thrown out of the inner cover. In this way, lint will not easily accumulate inside the shell 1.

[0020] The lower outer wall of the shell 1 is provided with a step 5. When too much lint fiber is wrapped around the outer wall of the inner shell 1, the worker can use a hook knife to move the lint to the step 5 of the shell 1, and then use the hook knife to hold the step 5 to cut the lint fiber, so as to easily clean away the wrapped lint fiber.

[0021] Multiple protruding ribs 4 are fixedly connected to the lower inner wall of the inner cover shell 1. These ribs 4 are vertically arranged and evenly distributed circumferentially. The ribs 4 are used for positioning the inner cover and the needle bar. The outer wall of the needle bar has multiple needle grooves. When the lower part of the inner cover shell 1 is fitted onto the needle bar, the ribs 4 can be positioned within the empty needle grooves of the needle bar for positioning, allowing the inner cover shell 1 to rotate with the needle bar. This positioning method facilitates the disassembly and cleaning of the inner cover shell 1. The specific thickness of the ribs 4 is 0.3mm. When the needle bar has no empty needle grooves, this thickness of rib 4 can still be positioned within the needle grooves without affecting the hook setting.
