[0002] As a high-precision and highly wear-resistant textile tool, the surface properties of crochet hooks directly affect production efficiency and product quality. Traditional crochet hooks are prone to problems such as yarn breakage and uneven stitches due to wear. Titanium nitride coating, due to its high hardness, low coefficient of friction and excellent corrosion resistance, can significantly improve the life of crochet hooks.

[0003] In the existing technology, when spraying textile crochet hooks, in order to improve the comprehensiveness of the spraying, the textile crochet hooks are usually rotated while being sprayed. At this time, the textile crochet hooks are prone to shaking in the fixture, or even falling off the fixture, thus affecting the normal processing of textile crochet hooks. Utility Model Content

[0004] This utility model proposes a low-temperature titanium nitride coating spraying fixture for textile crochet needles to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a spraying fixture, including a workbench, which is placed on the ground to provide support for the whole assembly. A shell is installed on the upper surface of the workbench, and a placement bucket is installed on the top of the shell. A spray nozzle is installed at the bottom of the placement bucket via a control valve, wherein the spray nozzle is located inside the shell. A cooling device is installed inside the shell, wherein the cooling device can reduce the temperature inside the shell. A movable platform is slidably connected to the upper surface of the workbench, and a limiting device is installed on the top of the movable platform, wherein the limiting device can limit the movement of the textile crochet hook.

[0006] The effect achieved by the above components is as follows: when spraying textile crochet hooks, the operator installs the textile crochet hooks on the moving platform through the limiting device. Then, the operator puts the moving platform into the inside of the outer shell, opens the control valve, and the paint inside the container is sprayed onto the surface of the textile crochet hook through the nozzle. The cooling equipment cools the inside of the outer shell, so that the textile crochet hook is sprayed at a low temperature, which improves the spraying effect of the textile crochet hook.

[0007] Preferably, the limiting device includes a motor embedded inside the moving platform. The motor is mounted on a support plate via a reducer. An mounting ring is mounted on the outer side of the support plate. The surface of the mounting ring is evenly provided with several arc grooves.

[0008] The aforementioned components achieve the following effects: When it is necessary to fix the textile crochet hook, the worker places the textile crochet hook into the arc groove of the mounting ring. Then, the worker rotates the fixing component, which moves towards the mounting ring. The fixing component presses against the inclined surface of the clamping plate, causing the clamping plate to move away from the mounting ring. The spring deforms, and after the fixing component moves past the clamping plate, the clamping plate moves above the fixing component under the action of the spring's return force, thus achieving the effect of fixing the fixing component. At this time, the semi-circular groove of the fixing component and the arc groove of the mounting ring hold the textile crochet hook in place, achieving the effect of fixing the textile crochet hook. When the textile crochet hook is sprayed, the motor is turned on, and the motor rotates the support plate, the mounting ring, and the textile crochet hook, making the textile crochet hook sprayed as evenly as possible. At this time, the L-shaped plate holds one end of the textile crochet hook against the ground, preventing the textile crochet hook from moving outward under the action of centrifugal force. The limiting device achieves the effect of fixing the textile crochet hook, preventing the textile crochet hook from shaking during rotational spraying, which would affect the normal spraying of the textile crochet hook.

[0009] Preferably, a control block is fixedly connected to one side of the fastener, wherein the surface of the control block is provided with anti-slip texture.

[0010] The effect achieved by the above components is to increase the contact area between the worker's hand and the fixed part by setting up control blocks, thereby making it easier for the worker to move the fixed part.

[0011] Preferably, a rubber pad is installed inside the semi-circular groove of the fastener, wherein the size of the rubber pad is adapted to the size of the semi-circular groove of the fastener.

[0012] The effect achieved by the above components is that by setting rubber pads, the friction between the textile crochet hook and the fixing parts is increased, thereby improving the fixing effect of the textile crochet hook.

[0013] Preferably, an auxiliary device is provided on one side of the mobile platform. The auxiliary device includes an iron plate, which is installed on the rear side of the mobile platform. A magnetic plate is installed inside the outer shell, wherein the magnetic plate and the iron plate attract each other.

[0014] The effect achieved by the above components is as follows: after the moving platform moves into the interior of the outer shell, the iron plate and the magnetic plate of the moving platform adhere to each other under the mutual attraction of the magnetic plate and the iron plate, thereby fixing the moving platform and preventing it from shaking during textile crochet spraying. The auxiliary device achieves the effect of fixing the moving platform, making it convenient for workers to install and disassemble the moving platform, and bringing convenience to textile crochet spraying.

[0015] Preferably, a handle is fixedly connected to the front side of the mobile platform, wherein the cross-section of the handle is U-shaped.

[0016] The aforementioned components achieve the following effect: by setting handles, they facilitate the movement of the mobile platform by staff, thus providing convenience for them.

[0017] Preferably, the bottom of the mobile platform is fixedly connected to two mutually symmetrical sliding plates, wherein the cross-section of the sliding plates is "T" shaped, and the worktable is provided with a sliding groove corresponding to the sliding plate, wherein the sliding plate and the sliding groove are slidably adapted.

[0018] The effect achieved by the above components is that by moving the sliding plate of the moving stage in the slide groove of the worktable, the direction of movement of the moving stage is restricted, thereby improving the stability of the moving stage.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] When it is necessary to fix the textile crochet hook, the worker places the textile crochet hook into the arc groove of the mounting ring. Then, the worker rotates the fixing component, which moves towards the mounting ring. The fixing component presses against the inclined surface of the clamping plate, and the clamping plate moves away from the mounting ring. The spring deforms. After the fixing component moves past the clamping plate, under the action of the spring's return force, the clamping plate moves above the fixing component, achieving the effect of fixing the fixing component. At this time, the semi-circular groove of the fixing component and the arc groove of the mounting ring hold the textile crochet hook in place, achieving the effect of fixing the textile crochet hook. When the textile crochet hook is sprayed, the motor is turned on. The motor rotates the support plate, the mounting ring, and the textile crochet hook, making the textile crochet hook sprayed as evenly as possible. At this time, the L-shaped plate holds one end of the textile crochet hook to prevent the textile crochet hook from moving outward under the action of centrifugal force.
