[0002] In the production of gun-punched carpets, a gun-punching weaving gun is typically used to insert yarns into the base fabric according to a specific pattern, thus forming the carpet. The weaving gun requires a drive mechanism to realize the weaving action and drive the yarns.
[0003] However, current carpet knitting guns have complex drive structures and high costs. Summary of the Invention
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a carpet knitting gun with a simple driving structure and reduced costs.
[0005] An embodiment of the present invention provides a carpet knitting gun, including a drive mechanism, a first transmission mechanism, and a knitting mechanism; the drive mechanism includes a motor and a rotating shaft disposed on the motor; the first transmission mechanism includes a first helical gear mounted on the end of the rotating shaft, a second helical gear meshing perpendicularly with the first helical gear, a gear shaft connected to the second helical gear, a first rocker assembly and a second rocker assembly mounted on both ends of the gear shaft; the knitting mechanism is used to perform knitting operations on a carpet base fabric, including a top fabric member connected to the first rocker assembly and knitting needles connected to the second rocker assembly.
[0006] A carpet knitting gun according to an embodiment of the present invention has at least the following advantages: by setting a first rocker assembly and a second rocker assembly, a motor and a first transmission mechanism drive the meshing transmission of a first helical gear and a second helical gear, thereby driving the first rocker assembly and the second rocker assembly, which in turn drives the knitting needle and the top fabric component to reciprocate. The actions of driving the knitting needle and the top fabric component can be completed simultaneously using a single motor, resulting in low cost.
[0007] According to some embodiments of the present invention, the device further includes a housing, in which the first helical gear and the second helical gear are mounted, the two ends of the gear shaft extend outside the housing, and the first rocker assembly and the second rocker assembly are located on both sides of the housing.
[0008] The advantages are: the housing protects the first transmission mechanism and isolates the yarn outside the housing, preventing it from tangling with the transmission components and reducing the occurrence of malfunctions. Furthermore, the gear shaft extends beyond the housing at both ends, allowing the first and second rocker assemblies to be mounted on either side of the housing. This eliminates the need to disassemble the housing for maintenance, facilitating repair and cleaning.
[0009] According to some embodiments of the present invention, a second transmission mechanism is further included, the second transmission mechanism including a first bevel gear mounted on the rotating shaft, a second bevel gear meshing with the first bevel gear, and a rotating shaft connected to the second bevel gear, the rotating shaft being used to drive the yarn forward.
[0010] The advantages are: understandably, by driving the first bevel gear with a motor, the meshing second bevel gear rotates, causing the rotating shaft to rotate, which in turn drives the yarn to move towards the knitting needle. Furthermore, both the first bevel gear and the first helical gear are coaxially mounted on the motor shaft, allowing a single motor to simultaneously drive the knitting mechanism and the yarn, resulting in a compact, simple, and low-cost structure.
[0011] According to some embodiments of the present invention, the rotating shaft extends to the outside of the housing, and the housing is further provided with a driven shaft for pressing the yarn toward the rotating shaft.
[0012] The advantage is that the yarn is located outside the housing, making it easy to replace. The driven shaft and the rotating shaft cooperate to clamp and drive the yarn. The gap between the driven shaft and the rotating shaft is adjustable, thereby controlling the tension of the yarn to adapt to the operating efficiency of the knitting gun and improving adjustability and applicability.
[0013] According to some embodiments of the present invention, the housing is further provided with a limiting block and a hinge block, and a channel for accommodating the passing of the yarn is formed between the limiting block and the hinge block, and the driven shaft rotates elastically around the hinge block.
[0014] The advantages are: the hinge block and the limiting block limit the yarn position, preventing the yarn from shifting or loosening, thus enabling the rotating shaft to accurately and effectively transmit the yarn, reducing malfunctions and errors, and improving the working efficiency of the knitting gun.
[0015] According to some embodiments of the present invention, the first rocker assembly includes a first crank, a first connecting rod, and a first slider connected to one end of the gear shaft, the first connecting rod connecting the first crank and the first slider, and the top fabric member being mounted on the first slider.
[0016] According to some embodiments of the present invention, the second rocker assembly includes a second crank, a second connecting rod, and a second slider connected to the other end of the gear shaft, the second connecting rod connecting the second crank and the second slider, and the knitting needle mounted on the second slider.
[0017] The advantage is that the motor drives the first crank and the second crank through the first transmission mechanism. The first crank and the second crank then drive the first connecting rod and the second connecting rod respectively. The first connecting rod and the second connecting rod are connected to the first slider and the second slider respectively, thereby driving the knitting needle and the top fabric to reciprocate and penetrate the carpet base fabric to complete the carpet weaving action.
[0018] According to some embodiments of the present invention, the front part of the housing is further provided with a mounting base, the first slider is provided with a first guide rod, the second slider is provided with a second guide rod, and the mounting base is provided with a first guide hole and a second guide hole for mounting the first guide rod and the second guide rod.
[0019] The advantage is that by setting a mounting base and providing a first guide hole and a second guide hole, it is beneficial to set the first guide rod and the second guide rod for the first slider and the second slider, so that the structure of the slider and the guide rod can move smoothly, is not easy to deviate, and the action is accurate and reliable.
[0020] According to some embodiments of the present invention, both the first guide rod and the second guide rod are provided in twos, and both the first guide hole and the second guide hole are provided in twos.
[0021] The advantages are that two guide rods are provided for both the first and second guide rods, which facilitates better installation of the first and second rocker assemblies on the mounting base, ensuring reliable and secure installation and adapting to the high-speed movement of the knitting needles and top fabric components.
[0022] According to some embodiments of the present invention, a pressure plate is further provided in front of the mounting base to accommodate the knitting needle and the top fabric member through which they pass.
[0023] The advantage is that by setting up a pressure plate to work in conjunction with the knitting needles and top fabric components, the weaving depth can be kept consistent, thus ensuring the quality of the carpet. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0034] The following is in conjunction with the appendix Figures 1-4 A carpet knitting gun according to an embodiment of the present invention is described, including a drive mechanism, a first transmission mechanism, and a knitting mechanism.
[0035] The drive mechanism includes a motor 100 and a rotating shaft 110 disposed on the motor 100; the first transmission mechanism includes a first helical gear 120 mounted on the end of the rotating shaft 110, a second helical gear 130 meshing perpendicularly with the first helical gear 120, a gear shaft 140 connected to the second helical gear 130, and a first rocker arm assembly 150 and a second rocker arm assembly 160 mounted on both ends of the gear shaft 140; the weaving mechanism is used to perform weaving operations on the carpet base fabric, and includes a top fabric piece 180 connected to the first rocker arm assembly 150 and a knitting needle 170 connected to the second rocker arm assembly 160.
[0036] By setting up a first rocker assembly 150 and a second rocker assembly 160, the motor 100 and the first transmission mechanism drive the meshing transmission of the first helical gear 120 and the second helical gear 130, thereby driving the first rocker assembly 150 and the second rocker assembly 160, which in turn drive the knitting needle 170 and the top fabric member 180 to reciprocate. A single motor 100 can simultaneously drive the knitting needle 170 and the top fabric member 180, resulting in low cost.
[0037] According to some embodiments of the present invention, the device further includes a housing 190, a first helical gear 120 and a second helical gear 130 mounted inside the housing 190, a gear shaft 140 extending to both ends outside the housing 190, and a first rocker assembly 150 and a second rocker assembly 160 located on both sides of the housing 190. The housing 190 serves to protect the first transmission mechanism and simultaneously isolates the yarn 230 outside the housing 190, preventing the yarn 230 from tangling with the transmission components and reducing the occurrence of malfunctions. Since both ends of the gear shaft 140 extend to the outside of the housing 190, and the first rocker assembly 150 and the second rocker assembly 160 can be mounted on both sides outside the housing 190, maintenance can be performed without disassembling the housing 190, facilitating repair and cleaning.
[0038] like Figure 3 As shown, it also includes a second transmission mechanism, which includes a first bevel gear 200 mounted on a rotating shaft 110, a second bevel gear 210 meshing with the first bevel gear 200, and a rotating shaft 220 connected to the second bevel gear 210. The rotating shaft 220 is used to drive the yarn 230 forward. The motor 100 drives the first bevel gear 200, which in turn drives the meshing second bevel gear 210 to rotate, causing the rotating shaft 220 to rotate, thereby driving the yarn 230 to move towards the knitting needle 170. Furthermore, the first bevel gear 200 and the first helical gear 120 are coaxially mounted on the rotating shaft 110 of the motor 100. A single motor 100 can simultaneously drive the knitting mechanism and the yarn 230, resulting in a compact, simple, and low-cost structure.
[0039] Specifically, the rotating shaft 220 extends to the outside of the housing 190, and the housing 190 is also provided with a driven shaft 240 for pressing the yarn 230 against the rotating shaft 220. This allows the yarn 230 to be located outside the housing 190 for easy replacement. The driven shaft 240 cooperates with the rotating shaft 220 to clamp and drive the yarn 230. The gap between the driven shaft 240 and the rotating shaft 220 is adjustable, thereby controlling the tension of the yarn 230 to adapt to the operating efficiency of the knitting gun and improve adjustability and applicability.
[0040] like Figure 3 and Figure 4 As shown, the housing 190 is also provided with a limiting block 250 and a hinge block 260. A channel for accommodating the yarn 230 is formed between the limiting block 250 and the hinge block 260. The driven shaft 240 rotates elastically around the hinge block 260. The hinge block 260 and the limiting block 250 limit the yarn 230, preventing the yarn 230 from shifting or loosening, thereby enabling the rotating shaft 220 to accurately and effectively transmit the yarn 230, reducing malfunctions and errors, and improving the working efficiency of the knitting gun.
[0041] Specifically, the first rocker assembly 150 includes a first crank 270, a first connecting rod 280, and a first slider 290 connected to one end of the gear shaft 140. The first connecting rod 280 connects the first crank 270 and the first slider 290, and a top fabric member 180 is mounted on the first slider 290. Correspondingly, the second rocker assembly 160 includes a second crank 300, a second connecting rod 310, and a second slider 320 connected to the other end of the gear shaft 140. The second connecting rod 310 connects the second crank 300 and the second slider 320, and a top knitting needle 170 is mounted on the second slider 320. The motor 100 drives the first crank 270 and the second crank 300 through the first transmission mechanism. The first crank 270 and the second crank 300 then drive the first connecting rod 280 and the second connecting rod 310 respectively. The first connecting rod 280 and the second connecting rod 310 are connected to the first slider 290 and the second slider 320 respectively, thereby driving the knitting needle 170 and the top fabric piece 180 to reciprocate, inserting into the carpet base fabric and completing the carpet weaving action.
[0042] In addition, a mounting base 330 is provided at the front of the housing 190. A first guide rod 340 is provided on the first slider 290, and a second guide rod 350 is provided on the second slider 320. The mounting base 330 is provided with a first guide hole 360 and a second guide hole 370 for mounting the first guide rod 340 and the second guide rod 350. By providing the mounting base 330 and the first guide hole 360 and the second guide hole 370, it is convenient to set the first guide rod 340 and the second guide rod 350 on the first slider 290 and the second slider 320, so that the structure of the slider and the guide rod moves smoothly, is not prone to deflection, and the operation is accurate and reliable.
[0043] Furthermore, both the first guide rod 340 and the second guide rod 350 are provided in pairs, and both the first guide hole 360 and the second guide hole 370 are provided in twos. The provision of two guide rods for both the first guide rod 340 and the second guide rod 350 facilitates better mounting of the first rocker assembly 150 and the second rocker assembly 160 on the mounting base 330, ensuring reliable and secure mounting and accommodating the high-speed movement of the knitting needle 170 and the top fabric component 180.
[0044] It is worth mentioning that a pressure plate 380 is also provided in front of the mounting base 330 to accommodate the knitting needles 170 and the top fabric piece 180. By setting the pressure plate 380 to work in conjunction with the knitting needles 170 and the top fabric piece 180, the weaving depth is kept consistent, ensuring the quality of the carpet.
