Description

Technical Field

[0001] This utility model relates to the field of embroidery machine technology, and in particular to a bead feeding mechanism. Background Technology

[0002] The bead feeding mechanism is used for stringing beads, continuously feeding beads onto the guide rod of the bead feeding mechanism in bead embroidery. The feeding mechanism typically includes a material container that works with the stringing rod, a driver that rotates the material container, a stringing rod with one end inserted into the material container, and the other end suspended outside to output beads, used to connect to the guide rod or directly forming the guide rod. To ensure continuous bead stringing, a feeding container is usually installed on the upper cover of the material container, with a discharge pipe at the bottom for discharging beads into the material cylinder. In existing technology, the feeding container is generally eccentrically mounted on the cover, often extending beyond the cover and occupying considerable space. During actual bead stringing, too many or too few beads in the material container are detrimental to stringing or normal use, reducing the stringing effect, causing beads to scatter, making stringing uncontrollable, and making the feeding mechanism unstable. Therefore, existing technologies typically include an adjustment mechanism. This mechanism comprises a baffle positioned at the feeding container's discharge port to control the material discharge. One end, one side, and / or both sides of the baffle are equipped with floating detection plates that naturally float within the feeding container to detect the height of the beads stacked inside. The baffle can control the material discharge speed or close the discharge port as the floating detection plates float. To better control the baffle's bead-blocking effect, a separate drive mechanism can be used to drive the baffle to block the beads. However, in existing technologies, the drive mechanism is generally located outside the feeding container, further increasing the space occupied by the entire feeding mechanism. When multiple beads are needed for embroidery, multiple feeding mechanisms must be spaced sufficiently apart, which is unsuitable for the current need for densely installed multiple embroidery machine heads, resulting in an insufficiently compact structure. Utility Model Content

[0003] To address the problems of the prior art, this utility model provides a bead feeding mechanism. The feeding container is concentrically mounted on the cover plate at the top of the placing container, and the driving mechanism of the driving baffle is also located inside the placing container. This reduces the overall volume of the feeding mechanism, making the structure more compact. Furthermore, the dropping of beads can be controlled by either electric control or a floating detection plate, resulting in better performance.

[0004] The technical solution adopted is as follows:

[0005] A bead feeding mechanism includes a feeding container and a driver for rotating the feeding container. The feeding container has a cover plate on top, and a feeding container is concentrically mounted on the cover plate. The feeding container has a feeding port at the bottom that allows the beads to fall into the feeding container. The feeding port has an adjustment structure for detecting the height of the beads stacked in the feeding container and adjusting the feeding speed according to the height of the beads stacked in the feeding container. A driving structure for driving the adjustment structure to control the feeding is also provided on one side of the adjustment structure. The driving structure is located inside the feeding container.

[0006] Furthermore, the adjustment structure includes a baffle set at the discharge port to control the discharge of materials. One end, one side, and / or both sides of the baffle are provided with floating detection plates that float naturally in the material container to detect the stacking height of beads in the material container. The baffle controls the discharge speed of the discharge port or closes the discharge port as the floating detection plates float.

[0007] Furthermore, the baffle is rotatably connected to the cover plate via a connecting arm.

[0008] Furthermore, the drive structure includes a drive cam mounted on the drive shaft and a drive block that pushes the connecting arm to block the discharge port or moves away from the connecting arm to allow the baffle to leave the discharge port and discharge material. The drive block and the drive cam are connected by a connecting rod.

[0009] Furthermore, the cover plate is provided with a mounting plate for mounting the drive block.

[0010] Furthermore, the drive block is provided with an elastic structure that drives the drive block to push the connecting arm.

[0011] Furthermore, the baffle is provided with a spring sheet structure that can block the material inlet, and the spring sheet structure is composed of several spring sheets.

[0012] Furthermore, the driver includes a drive motor and an output shaft.

[0013] Furthermore, the drive shaft may be a transmission shaft that drives the output shaft gear, or a power shaft that drives the ball clamping structure at the lower end of the material discharge container.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model provides a bead feeding mechanism, including a material container and a cover plate above the material container. The cover plate has a feeding container for feeding material into the material container. The feeding container is concentrically installed with the cover plate, and the volume of the feeding container extending slightly beyond the cover plate reduces the overall space required. An adjustment structure for adjusting the feeding speed is located at the feeding port at the lower end of the feeding container. A floating detection plate is located on one side of the adjustment structure, which can mechanically control the height of the material container. A drive structure is also provided to drive the adjustment structure to adjust the feeding speed. Using both mechanical and electric control methods for feeding results in better performance. The drive motor is located inside the material container and does not occupy space outside the container, making the structure more compact. This allows for a more compact installation of the feeding mechanism and the embroidery machine head, minimizing space requirements. Attached Figure Description

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] refer to Figure 1-6A bead feeding mechanism includes a material container 1 and a driver 2 for driving the material container 1 to rotate. The material container 1 is provided with a cover plate 3 on top, and a feeding container 4 is concentrically installed on the cover plate 3. The feeding container 4 is provided with a feeding port 5 at the bottom for discharging material into the material container 1. The feeding port 5 is provided with an adjustment structure 6 for detecting the stacking height of beads in the material container and adjusting and controlling the discharging speed of the feeding port according to the stacking height of beads in the material container. A driving structure 7 is also provided on one side of the adjustment structure 6 to drive the adjustment structure 6 to control the discharging. The driving structure 7 is located inside the material container 1.

[0025] The cover plate 3 is mounted on the external structure via a fixing bracket 12.

[0026] The feeding container 4 is concentrically mounted on the cover plate 3. Compared with the eccentric mounting of the prior art, the concentric mounting makes the volume of the feeding container 4 exceeding the cover plate 3 smaller, the overall space occupied by the mechanism is smaller, and the structure is more compact when multiple feeding mechanisms are installed.

[0027] The adjustment structure 6 includes a baffle 601 set at the discharge port 5 to control the discharge. One end, one side and / or both sides of the baffle 601 are provided with a floating detection plate 602 that floats naturally in the material container to detect the stacking height of beads in the material container. The baffle controls the discharge speed of the discharge port or closes the discharge port as the floating detection plate 602 floats.

[0028] Too many or too few beads in the feeding container 1 will affect bead threading. The floating detection plate 602 has a flat surface at its lower end. The height of the floating detection plate 602 can be set as the maximum critical height of the beads in the feeding container 1. A suitable height is selected so that the bead height does not affect bead threading. After the feeding container 4 drops beads, more and more beads are added to the feeding container 1, and the height of the beads in the feeding container 1 also increases. When the height of the beads is level with the floating detection plate 602, the bead height is the critical height. If the height of the beads continues to increase, the beads will cooperate with the flat surface at the lower end of the floating detection plate 602, pushing the floating detection plate 602 upward. At the same time, the baffle 7 also moves upward to block the dropping port 5, stopping the dropping of beads.

[0029] The baffle 7 is linked with the floating detection plate 6 to control the feeding speed of the feeding port 5. The floating detection plate 6 is a hinged, rotatable, or movable floating detection plate. The baffle 7, which is linked with the floating detection plate 6, controls the size of the feeding port 5 and changes the path of the beads, thereby controlling the feeding speed.

[0030] The baffle 601 is rotatably connected to the cover plate 3 via a connecting arm 8. One end of the connecting arm 8 is located on the cover plate 3, and the other end is connected to the baffle 601. The cover plate 3 is provided with a rotating shaft that rotates with the connecting arm 8.

[0031] The drive structure 7 includes a drive cam 702 mounted on a drive shaft 701 and a drive block 703 that pushes a connecting arm 8 to block the discharge port 5 or moves away from the connecting arm 8 to allow the baffle to leave the discharge port and allow material to fall. The drive block 703 is connected to the drive cam 702 via a connecting rod. The drive block is provided with an elastic structure that drives the drive block to push the connecting arm.

[0032] Driven by the elastic structure, the drive block 703 cooperates with the baffle 601 to push the baffle 601 to block the discharge port 5, preventing the material container 1 from discharging. When controlling the discharging, the drive shaft 701 rotates, causing the drive cam 702 to rotate. Since the drive cam is connected to the connecting arm 8 through a connecting rod, the cam 702 will cause the drive block 703 to move away from the baffle 601 through the connecting rod. The baffle 601 is not driven by the drive block 703 and, under the action of gravity, will swing downward around the axis with the connecting arm 8. Thus, it leaves the discharge port 5, and the material container 4 drops the bead downward.

[0033] The cover plate 3 is provided with a mounting plate 9 for mounting the drive block 703.

[0034] The baffle plate is provided with a spring structure 11 that can block the material discharge port. The spring structure 11 is composed of several spring pieces. The spring structure 11 is set at the ball drop position as a buffer to prevent the baffle plate 601 from providing too much force to the ball or crushing the ball when it comes into contact with the material discharge port 5, thus avoiding waste.

[0035] The driver 2 includes a drive motor 201 and an output shaft 202. The drive shaft 701 of the drive structure 7 can be a transmission shaft that drives the output shaft via gears, or a power shaft that drives the ball clamping structure 10 at the lower end of the material feeding container. The installation position of the drive motor 201 can also be adjusted according to actual needs.

[0036] The drive structure 7 is located inside the material container 1 and does not occupy the space outside the material container 1, further reducing the volume of the entire feeding mechanism. In multi-bead embroidery, multiple feeding mechanisms can be installed more compactly, and the embroidery machine head can also be installed more tightly. The overall structure is compact and occupies little space.

[0037] The cover plate is also provided with a through hole for the bead-threading rod to pass through. The bead-threading rod passes through the through hole into the material container 1, and the other end of the bead-threading rod is suspended on the outside to output beads, which is used to connect to the guide rod or directly form the guide rod. The rotating material container 1 drives the beads in the material container to move. The beads in the material container move relative to the bead-threading end of the fixed bead-threading rod. The moving beads pass through the bead-threading end of the bead-threading rod by probability. As the material container rotates, the beads are continuously passed through the bead-threading end. The beads that are passed through later push the beads that were passed through earlier to gradually slide along the bead-threading end to the other end of the bead-threading rod, so as to achieve continuous bead passing.

[0038] This invention not only employs an electrically controlled adjustment structure 6 to intermittently approach or move away from the feed inlet 5 to control whether and at what speed the beads fall, but also includes a floating detection plate that stops the bead falling when it exceeds a certain height limit. This allows for precise control of the bead falling without affecting the bead-stringing rod.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
