Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a bead-arranging and dropping device. Background Technology

[0002] A bead embroidery machine is a type of computerized embroidery machine, mainly used to automatically sew beads onto fabric according to a set pattern. It is characterized by a high degree of automation. A bead embroidery machine typically includes a bead placement mechanism, a bead dropping mechanism, and a bead feeding mechanism, which achieve automatic feeding of the beads through mechanical transmission.

[0003] Patent CN204265986U discloses a bead feeding device for an embroidery beading apparatus, comprising: a frame with a bead feeding mechanism on its upper part; a power drive distribution device fixedly mounted on the frame; a bead guide rod for guiding the embroidery beads to fall, the bead guide rod having a bead receiving section; an upper bead feeding section movably mounted on the frame, the upper bead feeding section including several upper section clamps, the power drive distribution device driving at least one upper section clamp to clamp the bead guide rod; and a lower bead feeding section movably mounted on the frame, the lower bead feeding section including a lower section clamp, the lower bead feed device driving the lower section clamp to clamp the bead guide rod, the lower section clamp having a certain distance between it and the nearest upper section clamp, so that sufficient embroidery beads can pass through the bead receiving section between the lower section clamp and the nearest upper section clamp. When the upper clamp of the bead feeding device is working, the bead feeding mechanism simultaneously feeds beads. If the upper clamp touches the guide rod, the guide rod located above the lower clamp will still shake and sway. As a result, the beads in the material cup cannot be accurately threaded onto the guide rod and fall down, but get stuck in the bead feeding hole at the bottom of the material cup, affecting the bead feeding. Utility Model Content

[0004] This invention aims to solve the problem of poor bead feeding and discharging in existing bead feeding devices for bead embroidery equipment. It provides a bead feeding and discharging device that can ensure production efficiency while keeping the guide wire completely stationary during bead feeding, thus completely avoiding the impact of the guide wire shaking or swaying on bead feeding.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A bead-discharging and dropping device of the present invention includes a frame, a bead-guiding wire, a drive shaft, and a material cup. The material cup is disposed on the top of the frame. Several time-sharing clamps are arranged longitudinally on the frame. The bead-guiding wire passes through the time-sharing clamps. The drive shaft is rotatably connected to the frame and drives the time-sharing clamps at intervals to open and close at intervals. The device also includes an alternating drive mechanism and a bead-sorting mechanism. The bottom of the material cup is provided with a bead-discharging hole. The upper end of the bead-guiding wire is aligned with the bead-discharging hole. The bead-sorting mechanism is disposed in the material cup so that the beads can fall into the bead-discharging hole in a specific orientation. The alternating drive mechanism is disposed on the frame and drives the bead-sorting mechanism and the drive shaft to work alternately. This invention employs an alternating drive mechanism to drive the bead-sorting mechanism and the drive shaft alternately. When the bead-sorting mechanism is working (sorting beads), the drive shaft stops driving the time-sharing clamp (stopping bead dropping). Conversely, when the bead-sorting mechanism stops working (stopping bead sorting), the drive shaft drives the time-sharing clamp (sorting beads), creating a stop-and-go relationship between the bead sorting and bead dropping processes. In short, this invention uses an alternating drive mechanism to alternate the bead sorting and bead dropping processes, ensuring production efficiency while maintaining the guide wire remains completely stationary during bead sorting, thus completely preventing bead sorting from being affected by swaying or shaking of the guide wire. The frame, time-sharing clamp, and drive shaft in this invention are all conventional mechanisms in the field; the bead-sorting mechanism can be selected according to the actual bead shape.

[0006] Preferably, the alternating drive mechanism includes a reversible motor, a first transmission mechanism, and a second transmission mechanism. The drive device is connected to the first and second transmission mechanisms respectively. The drive shaft is connected to the first transmission mechanism via a first one-way bearing, and the bead-scraping mechanism is connected to the second transmission mechanism via a second one-way bearing. The free rotation directions of the first and second one-way bearings are opposite. The reversible motor, through its forward and reverse rotation, and in conjunction with the first and second one-way bearings, enables the drive shaft and bead-scraping mechanism to work alternately, resulting in a simple structure.

[0007] Preferably, the first transmission mechanism includes a first belt drive pulley, a first belt driven pulley, and a first belt. The first belt drive pulley is fixedly connected to the output shaft of the forward and reverse motor. The first one-way bearing is fixed on the drive shaft. The first belt driven pulley is fixed outside the first one-way bearing. The first belt is wound and tensioned between the first belt drive pulley and the first belt driven pulley. The first transmission mechanism may also be a gear transmission mechanism.

[0008] Preferably, the second transmission mechanism includes a second belt drive pulley, a second belt driven pulley, and a second belt. The second belt drive pulley is fixedly connected to the output shaft of the forward and reverse motor. The second one-way bearing is disposed in the bead-sorting mechanism. The second belt driven pulley is connected to the bead-sorting mechanism via a transmission shaft that passes through the material cup and is connected to the second one-way bearing. The second transmission mechanism may also be a gear transmission mechanism.

[0009] Preferably, the bead-sorting mechanism includes a bead-sorting turntable, a second one-way bearing disposed in the bead-sorting turntable, a drive shaft passing through the second one-way bearing, a bead-sorting groove on the bead-sorting turntable, an isolation baffle on the inner wall of the material cup, the isolation baffle being located above the bead-sorting turntable, the isolation baffle, the bead-sorting turntable, and the inner wall of the material cup forming an independent bead-discharging chamber, the lower end of the side of the isolation baffle facing the rotation direction of the bead-sorting turntable having a bead-selecting port that allows only flat-bottomed drilled beads with their top surfaces facing upwards in the bead-sorting groove to pass through, and the bead-discharging hole being located on the bottom of the material cup below the bead-discharging chamber. The bead-sorting mechanism employs a bead-sorting turntable and other structures, enabling the placement and dropping of flat-bottomed, centrally-hole beaded beads. These flat-bottomed, centrally-hole beaded beads are a type of embroidery bead. Each beaded bead includes a frustum-shaped body and a cylindrical bottom. Both the body and bottom have bead-passing holes. The sides of the body are cut into multiple equally spaced continuous bevels. The end face of the body is the top surface, and the end face of the bottom is the bottom surface. When performing bead embroidery, the top surface of the flat-bottomed, centrally-hole beaded bead should be facing upwards. The longitudinal cross-sectional shape of the flat-bottomed, centrally-hole beaded bead is asymmetrical (smaller at the top and larger at the bottom). Utilizing this characteristic, the opening width of the bead-sorting opening can be set to be smaller than the width (diameter) of the bottom of the bead. When the bead-sorting turntable rotates, the flat-bottomed, centrally-hole drill beads rotate with it in the bead-sorting groove. When they reach the bead-selection port, the flat-bottomed, centrally-hole drill beads with their top surfaces facing upwards can enter the bead-discharging chamber through the bead-selection port. When the bead-sorting groove aligns with the bead-discharging port, the flat-bottomed, centrally-hole drill beads fall and pass through the guide wire, while the flat-bottomed, centrally-hole drill beads with their top surfaces facing downwards are blocked outside the bead-selection port because the width of the bottom of the drill is greater than the opening width of the bead-selection port. The isolation baffle also serves to isolate the flat-bottomed, centrally-hole drill beads in the material cup from entering the bead-discharging chamber. This utility model, through the cooperation of the bead-sorting turntable and the bead-selection port, can efficiently arrange the flat-bottomed, centrally-hole drill beads neatly and oriented them according to the required orientation, greatly improving production efficiency.

[0010] Preferably, the bead selection opening is provided with a flexible bead-removing sheet. The flexible bead-removing sheet is a soft and elastic sheet, which can be made of silicone. The flexible bead-removing sheet can push away the drill beads with incorrect orientation in the flat-bottomed center hole, and prevent them from getting stuck in the bead selection opening. Most preferably, the flexible bead-removing sheet has an opening that matches the bead selection opening.

[0011] Therefore, this utility model has the following beneficial effects: It is equipped with an alternating drive mechanism, which drives the bead feeding mechanism and the drive shaft to work alternately. While ensuring production efficiency, it also ensures that the guide wire remains completely still during bead feeding, thereby completely avoiding the impact of bead feeding caused by the shaking and swaying of the guide wire.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 , Figure 2The bead-discharging device shown includes a frame 1, a guide wire 2, a drive shaft 3, a material cup 4, an alternating drive mechanism 6, and a bead-sorting mechanism 7. The material cup is located on the top of the frame, and several time-sharing clamps 5 are arranged longitudinally on the frame. The guide wire passes through the time-sharing clamps. The drive shaft is rotatably connected to the frame and drives the time-sharing clamps to open and close at intervals. The bottom of the material cup has a bead-discharging hole 8, and the upper end of the guide wire is aligned with the bead-discharging hole. The bead-sorting mechanism is located inside the material cup so that the beads can fall into the bead-discharging hole in a specific orientation. The alternating drive mechanism is arranged on the frame to drive the bead-sorting mechanism and the drive shaft to work alternately. The alternating drive mechanism (such as...) Figure 3 (As shown) includes a reversible motor 9, a first transmission mechanism 10, and a second transmission mechanism 11. A drive device is connected to the first transmission mechanism and the second transmission mechanism respectively. The drive shaft is connected to the first transmission mechanism via a first one-way bearing 12. The bead-scraping mechanism is connected to the second transmission mechanism via a second one-way bearing 13. The free rotation directions of the first one-way bearing and the second one-way bearing are opposite. The first transmission mechanism includes a first belt drive pulley 14, a first belt driven pulley 15, and a first belt 16. The first belt drive pulley is fixedly connected to the output shaft of the reversible motor. The first one-way bearing is fixed on the drive shaft. The first belt driven pulley is fixed outside the first one-way bearing. The first belt is wound and tensioned between the first belt drive pulley and the first belt driven pulley. The second transmission mechanism includes a second belt drive pulley 17, a second belt driven pulley 18, and a second belt 19. The second belt drive pulley is fixedly connected to the output shaft of the reversible motor. The second one-way bearing is disposed in the bead-scraping mechanism. The second belt driven pulley is connected to the bead-scraping mechanism via a transmission shaft 20 that passes through the material cup and is connected to the second one-way bearing. Specifically, the bead-smoothing mechanism includes a bead-smoothing disc 21 (such as...) Figure 4 , Figure 5 , Figure 6 As shown), the second one-way bearing is installed in the bead-scraping turntable, the drive shaft passes through the second one-way bearing, the bead-scraping turntable is provided with bead-scraping grooves 22, and the inner wall of the material cup is provided with isolation baffles 23 (as shown). Figure 7 , Figure 8 As shown), the isolation baffle is located above the bead-sorting turntable. The isolation baffle, the bead-sorting turntable, and the inner wall of the material cup together form an independent bead-discharging chamber 24. The lower end of the side of the isolation baffle facing the rotation direction of the bead-sorting turntable is provided with a bead-selecting port 25, which can only allow flat-bottomed drilled beads with their top surfaces facing upwards in the bead-sorting groove to pass through. The bead-discharging hole is located on the bottom of the material cup below the bead-discharging chamber. A flexible bead-removing sheet 26 is provided at the bead-selecting port.

[0023] The operating principle of this utility model is as follows: When the forward and reverse motors rotate in one direction, they simultaneously drive the first transmission mechanism and the second transmission mechanism. If the first one-way bearing is in a locked state (transmitting power) at this time, the drive shaft rotates to drive the time-sharing clamp to open and close in a time-sharing manner, and the beads begin to fall. Since the free rotation directions of the first one-way bearing and the second one-way bearing are opposite, the second one-way bearing is in an idle state (not transmitting power), the drive shaft does not rotate, the bead-sorting turntable does not rotate, and the bead sorting stops. When the forward and reverse motors rotate in the opposite direction, the first one-way bearing switches to a locked state, the drive shaft does not rotate, the beads stop falling, the second one-way bearing switches to a locked state, the drive shaft rotates and drives the bead-sorting turntable to rotate, and the beads begin to be sorted.

[0024] The embodiments described above are merely preferred solutions of this utility model and are not intended to limit this utility model in any way. Other variations and modifications are possible without departing from the technical solutions described in the claims.
