[0002] In the traditional plastic weaving production process, there are often some residual silk winding on the winding drum after weaving, at which time personnel need to cut the residual silk on the winding drum with a blade to make it separate from the winding drum. Directly holding the blade to cut the silk on the winding drum, the cutting track is easy to be skewed, and it cannot be ensured that the multiple cutting is on the same straight track. This processing mode has high danger and is easy to cut the hand. CONTENT OF THE UTILITY MODEL

[0003] The utility model discloses a hand-operated silk cutter, and the operator can stably cut the silk on the winding drum, and ensure that the cutting track is on the same straight line, thereby greatly improving the cutting efficiency and accuracy.

[0004] The utility model discloses a technical scheme of a hand-operated silk cutter, which comprises a support, the support is provided with a silk falling port and a silk cutting assembly, the two ends of the silk falling port are provided with support part A and support part B capable of supporting the winding drum, the silk cutting assembly comprises a sliding shaft and a cutter on the sliding shaft, the sliding shaft is supported by a support, the sliding shaft is arranged on one side of the silk falling port and along the length direction of the silk falling port, the cutter comprises a blade and a handle, the blade can rotate around the sliding shaft and slide linearly under the driving of the handle, and the blade can rotate to approach or move away from the silk falling port.

[0005] By adopting the above technical scheme, the hand-operated silk cutter has the advantages of reasonable design, simple structure and convenient operation. The winding drum is placed on the support part A and the support part B, the operator holds the handle, drives the blade to rotate around the sliding shaft to approach the silk falling port to abut against the winding drum, and cuts the silk by driving the blade to slide linearly along the sliding shaft, and the cut silk can fall from the silk falling port. By using the sliding shaft and the cutter in the silk cutting assembly, the operator can stably cut the silk on the winding drum, and ensure that the cutting track is on the same straight line, thereby greatly improving the cutting efficiency and accuracy. Meanwhile, since the operation of the cutter is driven by the handle, the operator can conveniently control the cutting speed and force of the cutter, thereby further improving the cutting efficiency and accuracy. Moreover, the operator can move away from the blade, thereby reducing the risk of hand injury and improving the safety.

[0006] Further, the support part A is an insertion plate inserted into the inside of one end of the winding drum, the insertion plate is arranged on the inner end wall of the silk falling port, and the support part B has a card port on the end wall of the support and used for clamping the other end of the winding drum.

[0007] With the further setting, the design makes the yarn winding drum be able to be stably placed on the support A and the support B, and is not easy to slide or fall. The support A in the form of the plugboard can be deeply inserted into the inside of the yarn winding drum, and provide stable support force to prevent the yarn winding drum from shaking during cutting. The support B is designed as the bayonet, which can tightly clamp the other end of the yarn winding drum, and the cooperation of the support A and the support B can ensure that the yarn winding drum will not fall off or shift during cutting.

[0008] The further setting of the utility model discloses that the upper end of the bayonet has a V-shaped port, and the two sides of the insertion end of the plugboard have inclined surfaces.

[0009] With the further setting, the design further enhances the stability of the yarn winding drum on the support. The V-shaped port design of the upper end of the bayonet makes the bayonet more flexible to adapt to yarn winding drums of different diameters, ensures that the yarn winding drum can be tightly and stably clamped, and avoids the shaking or falling off problem caused by the diameter difference of the yarn winding drum. Meanwhile, the inclined surface design of the two sides of the insertion end of the plugboard makes the plugboard more smooth when inserted into the inside of the yarn winding drum.

[0010] The further setting of the utility model discloses that the blade is obliquely arranged, and the blade tip is obliquely downward when the blade is above the yarn dropping port, and the blade tail is used for mounting.

[0011] With the further setting, the design that the blade tip is obliquely downward can ensure that the silk thread is smoothly and cleanly cut, and avoids the silk thread residual problem caused by incomplete cutting. Meanwhile, the mounting design of the blade tail ensures that the blade can be firmly mounted on the silk cutter and will not be loose or fall off during cutting, further improves the safety and stability of cutting.

[0012] The further setting of the utility model discloses that a linear bearing capable of sliding and rotating is sleeved on the sliding shaft, a tool holder is arranged on the linear bearing, the blade and the handle are arranged on the tool holder, and the blade and the linear bearing are respectively connected to the two ends of the tool holder.

[0013] With the further setting, the design of the linear bearing makes the sliding and rotation of the tool holder on the sliding shaft more stable and smooth, reduces friction and resistance, and thus improves the operation flexibility and cutting efficiency of the silk cutter. Meanwhile, the blade and the handle are arranged on the tool holder and respectively connected to the two ends of the tool holder, so that the operator can more stably control the motion track of the blade when holding the handle to cut, and ensures the accuracy and consistency of cutting.

[0014] The further setting of the utility model discloses that the tool holder has a tool plate, a pressing strip is arranged on the tool plate, the tool tail of the blade is pressed on the tool plate by the pressing strip, and the two ends of the pressing strip are detachably connected to the tool plate.

[0015] With the further setting, the design of the pressing strip can effectively fix the blade tail of the blade, preventing the blade from loosening during the cutting process. Meanwhile, the two ends of the pressing strip are detachably connected to the cutter plate, which not only facilitates the installation and disassembly of the blade, but also facilitates the replacement and maintenance of the blade, improving the practicability and convenience of the wire cutter. In addition, the cutter plate, as part of the blade holder, cooperates with the pressing strip to provide a stable support platform for the blade, ensuring efficient and safe cutting operation.

[0016] The further setting of the utility model discloses: the support has a pair of clamping blocks, and the clamping hole for the end head of the sliding shaft is formed by the cooperation of the pair of clamping blocks, and the pair of clamping blocks are driven to approach by the screw to clamp the end head of the sliding shaft.

[0017] With the further setting, the pair of clamping blocks can firmly clamp the end head of the sliding shaft through the fastening action of the screw, ensuring the stability and precision of the sliding shaft on the support. This clamping method is not only simple and easy to operate, but also has high reliability and durability, and can adapt to long-time and high-strength cutting operation requirements. Meanwhile, the cooperation of the clamping block and the screw facilitates the installation and disassembly of the sliding shaft, improving the flexibility of the wire cutter.

[0018] The further setting of the utility model discloses: the sliding shaft is supported by two supports, and an anti-collision pad is arranged on the two ends of the sliding shaft, and the two anti-collision pads are correspondingly arranged on the inner sides of the two supports.

[0019] With the further setting, the setting of the anti-collision pad can effectively buffer the impact force that may be generated during the linear sliding of the cutter, protecting the cutter and the support from damage, reducing noise and vibration, and improving the stability and durability of the wire cutter.
