Description

Technical Field

[0001] This application relates to the field of wig production equipment technology, and in particular to an automatic feeding and dispensing mechanism for a three-piece wig machine. Background Technology

[0002] In wig production, the "three-in-one hairband weaving" is a crucial process that weaves hair material into basic hairpieces, and its weaving quality directly determines the quality of the final product. This process uses three dedicated sewing machines connected in series, requiring extremely high precision and stability.

[0003] Currently, this process relies entirely on manual operation by skilled workers—the operator must control the rotation speed with their foot while continuously and evenly pushing the flexible material with their fingers. This process demands extremely high levels of experience, concentration, and hand-eye coordination from the operator, resulting in high labor intensity, easy fatigue, low efficiency, and difficulty in ensuring consistent product quality.

[0004] The core challenge in automating this process lies in the significant softness and deformability of wig materials, with substantial differences in material, length, thickness, and smoothness between different products. This makes it difficult for mechanical devices to achieve stable grasping, combing, and precise feeding similar to a human hand. A search revealed no existing technology or market available for a three-unit automatic feeding system suitable for flexible wig materials.

[0005] Therefore, there is an urgent need in this field for an automated feeding device that can adapt to the special physical characteristics of the raw materials, in order to solve the technical bottlenecks of the three-piece knitting process, which relies on manual labor, is inefficient, and has large quality fluctuations. This invention is an automated solution proposed for this process. Summary of the Invention

[0006] In view of the above practical problems and the shortcomings of the existing technology, the main technical problem to be solved by the present invention is to provide an automatic feeding and dispensing mechanism for a three-piece wig machine, so as to realize automatic and continuous feeding of materials.

[0007] To solve the above-mentioned technical problems, this application provides an automatic feeding and dispensing mechanism for a three-piece wig machine, adopting the following technical solution:

[0008] An automatic feeding and dispensing mechanism for a three-piece wig machine includes a mounting frame and a horizontally moving platform module and a dispensing wheel assembly module disposed on the mounting frame; the mounting frame is detachably mounted on the table surface of the three-piece machine.

[0009] The mounting frame includes a forward / backward transmission structure and a feeding transmission structure. The forward / backward transmission structure drives the horizontal moving platform module to move back and forth in the direction toward the double-needle sewing machine. The feeding transmission structure drives the feeding wheel assembly module to feed material to the double-needle sewing machine in the direction toward the double-needle sewing machine. The horizontal moving platform module drives the feeding wheel assembly module to move up and down in a direction perpendicular to the platform.

[0010] The dispensing wheel assembly module includes a dispensing conveyor belt and a pressure adjustment module for the pressure roller. The dispensing conveyor belt has a built-in pressure roller, which can rotate with the rotation of the dispensing conveyor belt. The pressure adjustment module is connected to the pressure roller and is used to adjust the height of the pressure roller pressing against the platform in a direction perpendicular to the platform, so as to adjust the pressure of the pressure roller pressing down on the dispensing material.

[0011] The feeding transmission structure is connected to the feeding conveyor belt and drives the feeding conveyor belt to perform transmission. The feeding conveyor belt pulls the feeding material towards the direction of the double needle sewing machine through friction. When the feeding material is transported to the front of the presser foot of the double needle sewing machine, it is pressed down by the lower pressure wheel. The lower pressure wheel rotates to guide the feeding material under the presser foot of the double needle sewing machine.

[0012] In a preferred embodiment, the mounting platform includes a mounting structure and a frame structure. The mounting structure is fixed to the table surface of the three-unit machine. An electromagnet is embedded in the mounting structure, and the attraction surface of the electromagnet is arranged facing upward along the table surface. The forward and backward transmission structure and the discharge transmission structure are mounted on the frame structure.

[0013] The frame structure includes legs that can be attached to the electromagnet to fix the frame structure to the mounting structure. The electromagnet is externally energized and holds the legs in place when energized. When the power is turned off, the legs are released, thus releasing the fixation of the frame structure.

[0014] In a preferred embodiment, the forward and backward transmission structure includes a forward and backward motor, a forward and backward synchronous belt transmission structure, and a forward and backward lead screw. The horizontal moving table module includes a moving plate, and a lead screw nut is provided through the moving plate. The lead screw nut and the forward and backward lead screw form a helical transmission pair.

[0015] The forward and backward motor drives the forward and backward lead screw to rotate through the forward and backward synchronous belt transmission structure. The rotation of the forward and backward lead screw drives the lead screw nut to move linearly along the axial direction, thereby causing the moving plate to move back and forth in the direction of the double needle sewing machine.

[0016] In a preferred embodiment, a horizontal guide rail is provided on the movable plate along the direction toward the double-needle sewing machine, and a slider is provided on the bottom surface of the mounting frame; the slider slides with the horizontal guide rail, and the entire horizontal movable platform module is suspended below the mounting frame;

[0018] In a preferred embodiment, the generator transmission structure includes a generator, a motor moving base, and a forward / backward linear slide rail, wherein the forward / backward linear slide rail is arranged parallel to the horizontal guide rail; the motor moving base is slidably connected to the forward / backward linear slide rail, and the generator is fixed to the motor moving base;

[0019] A generator traction block is fixed on one side of the movable plate, and the generator traction block is connected to the motor moving seat; when the movable plate moves, it can drive the motor moving seat to move along the forward and backward linear slide rail.

[0020] In a preferred embodiment, the launch wheel module includes two sets of lower pressure frames arranged symmetrically on the left and right, and a main drive shaft passes through the two sets of lower pressure frames. The launch transmission structure also includes a main drive synchronous belt structure. The main drive shaft is driven to the launch conveyor belt.

[0021] One end of the main drive shaft passes through the lower pressure frame and is connected to the main drive synchronous belt structure. The main drive synchronous belt structure is connected to the generator. The generator drives the main drive shaft to rotate through the main drive synchronous belt structure, thereby driving the generator conveyor belt to operate.

[0022] In a preferred embodiment, the horizontal moving platform module includes a lifting motor and lifting guide rails disposed on both sides of the lifting motor, and the launching wheel assembly module includes a lifting slider for cooperating with the lifting guide rails;

[0023] The lifting guide rail is set in a direction perpendicular to the platform, the lifting slider slides on the lifting guide rail, the output end of the lifting motor is connected to the launch wheel assembly module, the lifting motor drives the launch wheel assembly module to move up and down in a direction perpendicular to the platform, and the lifting slider slides on the lifting guide rail;

[0024] Under the coordinated drive of the forward and backward transmission structure and the horizontal moving platform module, the release wheel module can move to a preset position on the side of the presser foot of the sewing machine or move away from the presser foot area of ​​the double needle sewing machine.

[0025] At the preset position, the side of the feed conveyor belt adjacent to the double-needle sewing machine is in close contact with the presser foot of the double-needle sewing machine, and the axis of the lower pressure roller corresponding to the side of the feed conveyor belt adjacent to the double-needle sewing machine extends beyond the bend of the presser foot in the horizontal direction.

[0026] In a preferred embodiment, the pressure roller pressure adjustment module includes a pressure roller motor, a pressure roller synchronous belt drive structure, a pressure roller lead screw, and a lifting baffle plate; a nut is provided on the lifting baffle plate, the pressure roller lead screw and the nut form a helical transmission pair, and the lifting baffle plate is connected to the pressure roller;

[0027] The pressure motor drives the pressure screw to rotate through the pressure roller synchronous belt transmission structure, thereby driving the lifting baffle to rise and fall in a direction perpendicular to the table surface, so as to adjust the height of the pressure roller from the table surface.

[0028] In a preferred embodiment, the pressure roller pressure adjustment module further includes a mounting baffle plate, which provides mounting space for the pressure roller synchronous belt drive structure, the pressure roller lead screw, and the lifting baffle plate;

[0029] The mounting folding plate is provided with a downward pressure guide rail on one side opposite to the lifting folding plate. The lifting folding plate is provided with a sliding block corresponding to the downward pressure guide rail. The sliding block is slidably connected to the downward pressure guide rail. When the lifting folding plate is raised and lowered, the sliding block can slide along the downward pressure guide rail.

[0030] The lifting folding plate is equipped with a connecting rod hinge seat, which is connected to the lower pressure wheel through a four-bar lower pressure module. When the lifting folding plate is raised or lowered, the lower pressure wheel is driven to swing or rise and fall along a corresponding trajectory through the four-bar lower pressure module.

[0031] In a preferred embodiment, the four-bar linkage pressing module includes an active link, a link fixed seat, a link movable seat, and a driven link. The pressing wheel is fixed on the link movable seat via a fixed shaft, and the pressing wheel is movably connected to the fixed shaft.

[0032] The connecting rod fixing seat is used to fix it on the generator wheel assembly module. The two ends of the driven connecting rod are respectively hinged to the connecting rod fixing seat and the connecting rod movable seat. The two ends of the driving connecting rod are respectively hinged to the connecting rod movable seat and the connecting rod hinge seat. The middle position of the driving connecting rod is hinged to the connecting rod fixing seat.

[0033] In summary, this application has the following beneficial effects:

[0034] 1. By combining the synergistic effect of the conveyor belt and the pressure roller, and using frictional traction in conjunction with mechanical pressing, the technical problem of the soft, easily deformed, and large size differences of wig materials, which makes automatic feeding difficult, is solved. This enables reliable automatic feeding of the three-piece weaving process, replacing the traditional purely manual operation mode.

[0036] 3. The horizontal moving table module completes the feeding and positioning in the forward and backward directions, the lifting motor drives the launching wheel group module to complete the vertical height adjustment, the pressure adjustment module of the lower pressure wheel completes the precise control of the clamping force, and the three-axis linkage meets the spatial posture requirements of complex weaving processes.

Loading and unloading can be completed without tools, which facilitates equipment maintenance, machine model switching and rapid deployment on the production site. Attached Figure Description

The hair conveyor module 3 adopts a symmetrical arrangement of left and right structures. The layout and installation of the left and right structures are the same. Taking the left structure as an example, its specific composition and cooperative relationship are described below. Figure 13 As shown, the launch wheel assembly module 3 includes a left lower pressure frame (3-1), a left locking block (3-2), a left tensioning shaft (3-3), a left launch tensioning wheel (3-4), a left launch conveyor belt (3-5), a left launch drive pulley (3-6), a main drive shaft (3-7), a pressure wheel pressure adjustment module (3-8), and a four-bar lower pressure module (3-9).

[0088] like Figure 14As shown, a left tensioning mechanism is provided at one end of the lower left pressure frame (3-1) to maintain a constant tension on the left discharge conveyor belt (3-5). The left tensioning mechanism includes a left locking block (3-2), a left tensioning shaft (3-3), and a left discharge tensioning wheel (3-4). The left locking block (3-2) is fixed to one end of the lower left pressure frame (3-1) by bolts. The left locking block (3-2) is used to lock the fixing shaft of the left tensioning shaft (3-3) that passes through its slot, thus fixing the left tensioning shaft (3-3) to the end of the lower left pressure frame (3-1).

[0089] The left lower pressure frame (3-1) has a left tensioning plate (3-11) fixed on the inner side of the end where the left locking block (3-2) is located. The left tensioning plate (3-11) has an elongated slot. The left tensioning plate (3-11) is locked to the inner side of the left lower pressure frame (3-1) through the elongated slot and bolts. The design of the elongated slot on the left tensioning plate (3-11) allows the locking position of the left tensioning plate (3-11) to be adjusted back and forth along the length of the slot, thereby driving the left tensioning shaft (3-3) and the left discharge tensioning wheel (3-4) installed on the left tensioning shaft (3-3) to move, so as to realize the tension adjustment of the left discharge conveyor belt (3-5).

[0090] When the tension of the left conveyor belt (3-5) needs to be adjusted, first remove the left locking block (3-2) from the left lower pressure frame (3-1), then adjust the locking position of the left tension plate (3-11) back and forth through the long slot on the left tension plate (3-11). After adjusting to the appropriate tension position, lock the left tension plate (3-11) to the inside of the left lower pressure frame (3-1), and finally re-lock the left locking block (3-2) to the left lower pressure frame (3-1) to lock the fixed shaft of the left tension shaft (3-3).

[0091] The power supply for the generator set module 3 is provided by the generator (1-4-1). The main drive shaft (3-7) passes between the left lower pressure frame (3-1) and the right lower pressure frame (3-10). A left generator drive pulley (3-6) is mounted on the main drive shaft (3-7). The left generator conveyor belt (3-5) winds around the left generator tensioning pulley (3-4) and the left generator drive pulley (3-6), forming a belt conveyor structure. Figure 15 As shown, the end of the main drive shaft (3-7) extends through the lower left pressure frame (3-1) and is equipped with a secondary drive pulley (3-14), as... Figure 16As shown, the auxiliary drive pulley (3-14) is connected to the main drive pulley (1-4-3) of the output shaft of the generator (1-4-1) via a main drive synchronous belt (3-16). When the generator (1-4-1) starts, the rotation of the main drive pulley (1-4-3) drives the main drive synchronous belt (3-16) to transmit the rotation of the output shaft of the generator (1-4-1) to the main drive shaft (3-7), which in turn drives the main drive shaft (3-7) to rotate, thereby realizing the transmission motion of the left generator conveyor belt (3-5). The main drive synchronous belt (3-16), the main drive pulley (1-4-3), and the auxiliary drive pulley (3-14) constitute the main drive synchronous belt structure.

[0092] The tension adjustment of the main drive synchronous belt (3-16) is performed by the tension adjustment unit of the generator transmission structure (1-4). For example... Figure 17 As shown, the main drive synchronous belt (3-16) passes sequentially around the main drive pulley (1-4-3), the tension pulley (1-4-4), and the auxiliary drive pulley (3-14). Through the tension pulley (1-4-4) and the tension spring (1-4-6), an elastic tension adjustment unit is formed, which can compensate for the changes in the tension of the main drive synchronous belt (3-16) in real time and maintain a constant tension.

[0093] To accommodate different working heights, the launch wheel assembly module 3 has an overall lifting function, with the lifting power provided by the horizontal moving platform module 2. For example... Figure 15 As shown, lifting sliders are provided on the inner sides of both the lower left pressure frame (3-1) and the lower right pressure frame (3-10). The inner side of the lower left pressure frame (3-1) is provided with a left front lifting slider (3-12) and a left rear lifting slider (3-13) spaced apart along its length. A left lifting mounting hole (3-15) is provided between the left front lifting slider (3-12) and the left rear lifting slider (3-13). Figure 18 As shown, the left lifting mounting hole (3-15) is provided through the end face of the left lower pressure frame (3-1). The right lower pressure frame (3-10) and the left lower pressure frame (3-1) are symmetrically arranged with these structures.

[0094] like Figure 19 As shown, the left lifting mounting hole (3-15) is connected to the left lifting rod (2-10), for reference. Figure 19 The structure of section D. The left and right lifting motors set in the horizontal moving platform module 2 drive the left and right lifting rods to rise and fall, thereby acting on the left and right lower pressure frames, and in turn driving the entire launching wheel assembly module 3 to rise and fall, realizing the overall lifting and positioning relative to the worktable.

[0095] like Figure 20As shown, to facilitate stable lifting, the left front lifting slider (3-12) and the left rear lifting slider (3-13) are respectively slidably connected to the left front lifting guide rail (2-12) and the left rear lifting guide rail (2-15) respectively provided on the horizontal moving platform module 2. (Refer to...) Figure 20 The structure of section E. The entire launch wheel module 3 is guided by its left and right lifting sliders in conjunction with the lifting guide rails of the horizontal moving platform module 2.

[0096] In order to achieve stable pressing of the material, the discharge wheel module 3 is equipped with a pressure roller pressure adjustment module (3-8) and a four-bar pressing module (3-9). The pressure roller pressure adjustment module (3-8) and the four-bar pressing module (3-9) are arranged on both the left and right sides of the structure.

[0097] like Figure 21-22 As shown, the pressure roller pressure adjustment module (3-8) includes a mounting baffle (3-8-1), a pressure roller synchronous belt drive structure (including a main drive wheel (3-8-4), a driven drive wheel (3-8-3), and a synchronous belt (3-8-2)), a pressure motor (3-8-6), a sliding block (3-8-7), a pressure guide rail (3-8-8), a lifting baffle (3-8-9), and a pressure screw (3-8-11).

[0098] like Figure 22 As shown, the pressure roller pressure adjustment module (3-8) is installed as a whole on the outside of the lower left pressure frame (3-1) by means of the mounting folding plate (3-8-1). A folding plate connecting plate (3-8-14) is fixed on one side of the mounting folding plate (3-8-1). The folding plate connecting plate (3-8-14) is bolted to the outside of the lower left pressure frame (3-1).

[0099] like Figure 21 As shown, a downward pressure motor mounting base (3-8-5) is fixed to one side of the mounting plate (3-8-1). The downward pressure motor (3-8-6) is fixed to the downward pressure motor mounting base (3-8-5). The downward pressure motor (3-8-6) serves as the core driving element, and its output shaft is connected to the main drive wheel (3-8-4). One end of the downward pressure lead screw (3-8-11) is connected to the driven drive wheel (3-8-3), and its other end is fitted with a nut (3-8-10). The nut (3-8-10) is fixed to the slide block (3-8-9).

[0100] The mounting plate (3-8-1) has a mounting hole (3-8-12) for the pressing screw (3-8-11), and the pressing screw (3-8-11) passes through the mounting hole (3-8-12) and engages with the nut. The pressing guide rail (3-8-8) is fixed inside the lower side wall of the mounting plate (3-8-1), and the sliding block (3-8-7) is fixed on the side plate (3-8-13) of the lifting plate (3-8-9) facing the pressing guide rail (3-8-8), and the sliding block (3-8-7) slides on the pressing guide rail (3-8-8).

[0101] When the pressure motor (3-8-6) starts, it drives the main drive wheel (3-8-4) to rotate, thereby driving the synchronous belt (3-8-2) to drive the driven wheel (3-8-3) to rotate. The rotation of the driven wheel (3-8-3) drives the pressure screw (3-8-11) to rotate. The pressure screw (3-8-11) cooperates with the nut (3-8-10) to convert the rotational motion into linear lifting, thereby driving the lifting plate (3-8-9) to move along the guide direction of the pressure guide rail (3-8-8) under the sliding cooperation of the sliding block (3-8-7) and the pressure guide rail (3-8-8).

[0102] like Figure 22 As shown, two downward guide shafts (3-8-17) are symmetrically arranged on the panel of the lifting folding plate (3-8-9). Each downward guide shaft (3-8-17) is connected to the panel through a copper sleeve (3-8-16). The downward guide shaft (3-8-17) and the copper sleeve (3-8-16) cooperate to ensure stability. A connecting rod hinge seat (3-8-15) is fixed at the upper end of the downward guide shaft (3-8-17). The connecting rod hinge seat (3-8-15) is used to connect the four-link downward module (3-9).

[0103] like Figure 23 As shown, the four-bar linkage pressing module (3-9) includes an active link (3-9-1), a link fixing seat (3-9-2), a link movable seat (3-9-3), a fixed shaft (3-9-4), a pressing wheel (3-9-5), and a driven link (3-9-6).

[0104] The connecting rod fixing seat (3-9-2) is fixedly installed on the inner side of the left lower pressure frame (3-1), and the four-link pressing module (3-9) is installed on the left lower pressure frame (3-1) as a whole through the connecting rod fixing seat (3-9-2).

[0105] The driving link (3-9-1) and the driven link (3-9-6) constitute a force-multiplying mechanism. The two ends of the driven link (3-9-6) are respectively hinged to the link fixed seat (3-9-2) and the link movable seat (3-9-3). One end of the driving link (3-9-1) is hinged to the link movable seat (3-9-3). Figure 24 As shown, the middle part of the active connecting rod (3-9-1) is hinged to the connecting rod fixing seat (3-9-2), and its other end extends out of the connecting rod fixing seat (3-9-2) and is hinged to the connecting rod hinge seat (3-8-15). (Reference) Figure 24 The structure of part F. The outer wall of the connecting rod movable seat (3-9-3) opposite to the connecting rod fixed seat (3-9-2) is connected to the lower pressure wheel (3-9-5) through the fixed shaft (3-9-4), and the lower pressure wheel (3-9-5) is rotatably connected to the fixed shaft (3-9-4).

[0106] like Figure 24 As shown, the lower pressure wheel (3-9-5) is positioned between the left feeding conveyor belts (3-5) and can rotate with the transmission of the left feeding conveyor belts (3-5). The lower pressure wheel (3-9-5) is used to adjust the downward pressure of the left feeding conveyor belts (3-5) on the feeding material. Specifically, the lifting baffle (3-8-9) drives the connecting rod hinge seat (3-8-15) to move up and down under the drive of the lower pressure motor (3-8-6). The lifting of the connecting rod hinge seat (3-8-15) acts on the connecting rod movable seat (3-9-3) through the active connecting rod (3-9-1), so that the connecting rod movable seat (3-9-3) can swing up and down, thereby driving the lower pressure wheel (3-9-5) to swing up and down, so as to achieve precise adjustment of the downward pressure.

[0107] The automatic feeding and dispensing mechanism of the wig triplex machine provided in this embodiment, such as Figures 25-26 As shown, the working principle is as follows:

[0108] Before starting work, place the left support leg (1-2-1) and right support leg of the frame structure (1-2) of the mounting platform 1 on the electromagnet fixing seat (1-1-1), turn on the power of the electromagnet (1-1-2) so that it attracts and fixes the support leg, thereby firmly installing the entire automatic feeding and discharging mechanism on the table surface (4-1) of the three-unit machine.

[0109] After the entire automatic feeding and dispensing mechanism is fixed, the left lifting motor (2-8) and the right lifting motor are started, driving the left lifting rod (2-10) and the right lifting screw to rotate, thereby raising and lowering the entire dispensing wheel assembly module 3 to adapt to different worktable heights. Once the appropriate height is reached, the left lifting motor (2-8) and the right lifting motor stop operating. Then, the forward and backward motor (1-3-1) is started, driving the forward and backward screw (1-3-8) to rotate, moving the entire horizontal moving platform module 2 and the dispensing wheel assembly module 3 it carries towards the double-needle sewing machine (4-2). When the left and right lower pressure rollers (3-9-5) of the dispensing wheel assembly module 3 move to a preset position on the side of the presser foot of the double-needle sewing machine, the forward and backward screw (1-3-8) stops. The preset position requires that the right side of the left dispensing conveyor belt (3-5) be closely adjacent to the presser foot of the double-needle sewing machine (4-2); simultaneously, the axis of the left lower pressure roller should extend slightly beyond the bend of the presser foot in the horizontal direction.

[0110] Next, start the left and right pressure motors (3-8-6). Through the cooperation of the pressure roller pressure adjustment module (3-8) and the four-bar pressure module (3-9), adjust the pressure of the left and right pressure rollers (3-9-5) to accurately set the pressure of the left and right pressure rollers (3-9-5) on the material feeding. After the pressure adjustment is completed, stop the left and right pressure motors (3-8-6) and start the generator (1-4-1). The generator (1-4-1) transmits power to the left feeding conveyor belt (3-5) and the right feeding conveyor belt through the main drive synchronous belt (3-16), thereby driving the left feeding conveyor belt (3-5) and the right feeding conveyor belt to rotate in the direction of the sewing machine presser foot.

[0111] At this point, the fabric to be woven is placed at the starting end of the conveyor belt on the left and right sides of the drive pulley (3-6). The left and right conveyor belts pull the fabric forward through friction. When the fabric is conveyed to the front of the presser foot of the sewing machine, it is stably guided under the presser foot by the pre-pressed lower roller (3-9-5), and then the sewing machine is started to complete the weaving operation.

[0112] Boll thread replacement procedure: When the sewing machine runs out of boll thread, knitting must be paused. Restart the forward / reverse motor (1-3-1) to drive the horizontal moving table module 2 and the feed roller assembly module 3 to move backward as a whole until they are completely removed from the presser foot area of ​​the sewing machine. At this point, the operator should open the boll thread cover and replace the boll thread. After replacement, restart the forward / reverse motor to move the entire module back to the working position, and then the machine can be loaded again to continue automatic feed knitting operations.

[0113] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
