Description

Technical Field

[0001] This utility model relates to the technical field of carpet processing equipment, and particularly to a flocking needle and scissor device for a carpet flocking machine. Background Technology

[0002] In the field of carpet processing technology, flocking machines are a commonly used type of processing equipment. Flocking machines are used to flock fibers onto the carpet backing fabric, forming the carpet surface. Afterwards, adhesive is applied to the back of the backing fabric for bonding and curing, thus bonding and fixing it to the other layers of the carpet to form a complete carpet product. Generally, flocking machines are used for the flocking operation, which requires a high degree of uniformity in the pile height after flocking.

[0003] When flocking carpets, different types of flocking needles and matching scissors are required depending on the type of pile yarn. Therefore, for carpet flocking machines, there is an operation to select and change flocking needles and scissors in their application scenarios. Due to structural design limitations, the aforementioned operation of changing flocking needles and scissors in existing carpet flocking machines is quite cumbersome. Moreover, the repeatability of flocking needles and scissors is insufficient. In addition to the cumbersome operation, the machines often fail to operate normally after component replacement due to the repeatability of component positioning, requiring further adjustments.

[0004] In summary, it is necessary to develop and design flocking needles and scissor devices for use in carpet flocking machines to solve the aforementioned technical problems. Summary of the Invention

[0016] To further understand the invention content, features and effects of this utility model, the following embodiments are provided in detail.

[0017] Depending on the type of flocking yarn used by the flocking machine, this flocking needle and scissor device has two specific structural forms, corresponding to both cut and loop flocking yarn types. The two specific structural forms can be selected and interchanged, allowing the same carpet flocking machine to be used for both cut and loop flocking carpets. Example

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The flocking needle and scissor device of the carpet flocking machine of this utility model includes an upper slider 1 and a lower slider 2. The upper slider 1 and the lower slider 2 are installed on the upper and lower guide slides of the carpet flocking machine and are driven alternately by the flocking machine drive assembly. That is, the upper slider 1 moves forward along the guide slide while the lower slider 2 moves backward. Then, the upper slider 1 moves backward along the guide slide while the lower slider 2 moves forward, and so on to perform continuous flocking operations.

[0019] An upper groove is provided at the bottom of the upper slider 1, and an upper base plate 3 is fixedly installed in the upper groove using assembly bolts 5. A lower groove is provided at the top of the lower slider 2, and a lower base plate 4 is fixedly installed in the lower groove using assembly bolts 5. The upper base plate 3 has an exposed portion in front of the upper slider 1, and a flocking needle assembly is fixedly installed on the exposed portion using fixing screws 6. The lower base plate 4 has an exposed portion in front of the lower slider 2, and a scissor assembly is fixedly installed on the exposed portion using fixing screws 6. During the aforementioned alternating movement, when the flocking needle assembly moves forward, it inserts the flocking into the base fabric; when the scissor assembly moves forward, it cuts the flocking.

[0020] In this embodiment, the rear part of the upper substrate 3 is located within the upper groove, and the upper substrate 3 is the same width as the upper groove. The upper substrate 3 is fixedly connected to the upper slider 1 using two assembly bolts 5. In this embodiment, the rear part of the lower substrate 4 is located within the lower groove, and the lower substrate 4 is the same width as the lower groove. The lower substrate 4 is fixedly connected to the lower slider 2 using two assembly bolts 5.

[0021] In this embodiment, two threaded holes are provided on the exposed portion of the upper substrate 3, and two threaded holes are provided on the exposed portion of the lower substrate 4. The ends of each fixing screw 6 are screwed into the corresponding threaded holes to achieve positioning and fixing of the components. When replacing the flocking needle assembly and the scissor assembly, each fixing screw 6 is removed, and after replacing the components, the fixing screws 6 are used to fix the components to the upper substrate 3 and the lower substrate 4.

[0022] Please see Figure 2 , Figure 3 and Figure 4 It can be seen that: The flocking needle assembly includes a flocking needle 7, which has a needle groove and two connecting holes at the rear. The front part of the upper substrate 3 is located in the needle groove and is fixedly connected to the flocking needle 7 by two fixing screws 6.

[0024] The assembly also includes a flocking shear 11 and a spring plate 10, with the flocking shear 11 positioned above the spring plate 10. The rear part of one side of the shearing shear 11's handle and the rear part of the spring plate 10 are fixedly connected to the shear base 8 using flocking shear fixing bolts 9. The spring plate 10 is used to lift the front part of the flocking shear 11 upwards, causing the flocking shear 11 to bend slightly towards the flocking needle 7. The rear part of the other side of the shearing shear 11's handle has an outward-facing protrusion. As the shear assembly moves back and forth with the lower slider 2, the outer protrusion interacts with a protrusion on the trigger plate on the flocking machine body during its reciprocating movement, causing the shears to engage when moving forward to the end position to cut the flock, and to open again when moving backward. Example

[0025] Please see Figure 5 , Figure 6 and Figure 7 The flocking needle and scissor device of the carpet flocking machine of this utility model includes an upper slider 1 and a lower slider 2. The upper slider 1 and the lower slider 2 are installed on the upper and lower guide slides of the carpet flocking machine and are driven alternately by the flocking machine drive assembly. That is, the upper slider 1 moves forward along the guide slide while the lower slider 2 moves backward. Then, the upper slider 1 moves backward along the guide slide while the lower slider 2 moves forward, and so on to perform continuous flocking operations.

[0026] An upper groove is provided at the bottom of the upper slider 1, and an upper base plate 3 is fixedly installed in the upper groove using assembly bolts 5.
