Description

Technical Field

[0001] This utility model relates to the field of bead embroidery technology, and in particular to an automatic feeding device. Background Technology

[0002] Currently, bead-threading mechanisms used in conjunction with bead embroidery typically incorporate a feed container on the material cylinder to increase the continuity of bead threading. The bottom of this feed container has a discharge pipe that inserts into the material cylinder. Existing feed containers have a bottom cover at the discharge port of the discharge pipe to control its on / off state. This bottom cover has a transmission control structure that controls the opening and closing of the discharge port. This transmission control structure is usually located outside the material cylinder, occupying a significant amount of space. External transmission during use is potentially dangerous and also hinders the installation of multi-bead feeding devices.

[0003] There are also structures that place the drive inside the material barrel, but their transmission design is not reasonable enough, and the control of the bottom cover opening and closing does not meet the requirements of automatic material dropping. Utility Model Content

[0004] To address the problems of the prior art, this utility model provides an automatic feeding device with a stop cover at the discharge port. The stop cover is closed by a pressure-driven component, and the rotating component cooperates with the pressure-driven component to periodically open and close the stop cover, automatically feeding beads intermittently into the material cylinder and adaptively replenishing the consumption of beads in the material cylinder.

[0005] The technical solution adopted is as follows:

[0006] An automatic feeding device includes a material cylinder for inserting a guide rod and for threading beads with the guide rod. The upper end of the material cylinder has a feeding container, and the bottom of the feeding container has a discharge pipe inserted into the material cylinder. The lower end of the discharge pipe has a discharge port, and the discharge port has a stop cover hinged to the discharge port. The discharge pipe has a driving assembly for driving the stop cover to close the discharge port. The driving assembly includes a driving arm rotatably mounted on the discharge pipe to close the stop cover, a driving rod rotatably mounted on the discharge pipe to drive the driving arm to rotate, and a transmission rod located between the driving arm and the driving rod. The material cylinder or propeller has a rotating component that rotates with the rotation of the material cylinder or propeller and can periodically drive and disengage from the driving rod to periodically open and close the stop cover. The rotating component is located inside the material cylinder.

[0007] Furthermore, the upper end of the stop cover is provided with a pressure rod for closing the stop cover, the pressure rod is provided with a pressure spring, and the pressure arm is provided with a pin for closing the pressure rod.

[0008] Furthermore, the pin is adjustablely mounted on the pressure arm.

[0009] Furthermore, the middle part of the driving arm is rotatably mounted on the discharge pipe, one end of the driving arm is connected to the transmission rod, and the other end is connected to the discharge pipe through a tension spring.

[0010] Furthermore, the discharge port is provided with a buffer connector that mates with the stop cover for cushioning.

[0011] Furthermore, the rotating component is a concentric shaft disposed on the barrel and concentric with the barrel, or a concentric shaft disposed on the propeller and concentric with the propeller, wherein the concentric shaft is provided with a driving protrusion that can rotate with the concentric shaft and periodically cooperate with the drive rod.

[0012] Furthermore, the lower end of the material cylinder is provided with a drive mechanism for driving the material cylinder to rotate.

[0013] Furthermore, the drive mechanism includes a drive motor, a first gear mounted on the drive motor, a drive shaft for driving the material cylinder to rotate, a second gear mounted on the drive shaft, and a synchronous belt between the first and second gears.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model provides an automatic material feeding device, including a material cylinder and a feeding container. The lower end of the feeding container has a discharge pipe that inserts into the material cylinder, and the lower end of the discharge pipe has a discharge port. A stop cover and a driving assembly that drives the stop cover to cover the discharge port are rotatably mounted at the discharge port. The driving assembly includes a driving arm and a driving rod rotatably mounted on the discharge pipe, and a transmission rod between the driving arm and the driving rod. A rotating component on the material cylinder or propeller rotates with the material cylinder or propeller, driving the driving rod. The rotating component cooperates with the driving arm to intermittently open and close the stop cover. The rotating component is mounted on the concentric shaft of the material cylinder or propeller, eliminating the need for additional power drive structures, simplifying the structure, and saving costs.

[0017] The driving arm is equipped with a pin for pressing down the stop cover. The stop cover has a pressure rod and a driving spring at its upper end. The pin presses down the pressure rod to close the stop cover, and the driving arm has a tension spring that presses down on the stop cover. The pin and pressure rod work together to drive the downward pressure, resulting in better clamping. When closed, the stop cover more tightly blocks the discharge port. The periodic opening and closing of the stop cover is controlled by a driving rotating component that presses or disengages from the driving rod. This operation allows for intermittent feeding into the material cylinder, adaptively replenishing the beads consumed and improving bead threading efficiency. The entire driving assembly is mounted on the discharge pipe, allowing for easy and efficient installation and disassembly. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments.

[0027] refer to Figure 1-8An automatic feeding device includes a material cylinder 1 for inserting a guide rod and for threading beads with the guide rod. The upper end of the material cylinder 1 is provided with a feeding container 2, and the bottom of the feeding container 2 is provided with a discharge pipe 3 inserted into the material cylinder 1. The lower end of the discharge pipe 3 is provided with a discharge port 4. The discharge port 4 is provided with a stop cover 5 hinged to the discharge port. The discharge pipe 3 is provided with a driving pressure component 6 for driving the stop cover to cover the discharge port. The driving pressure component 6 includes a driving pressure arm 601 rotatably disposed on the discharge pipe to drive the stop cover to close, a driving rod 602 rotatably disposed on the discharge pipe to drive the driving pressure arm to rotate, and a transmission rod 603 disposed between the driving pressure arm and the driving rod. The material cylinder 1 or the propeller is provided with a rotating component 7 that rotates with the rotation of the material cylinder 1 or the propeller and can periodically drive and disengage from the driving pressure driving rod to drive the stop cover to periodically open and close. The rotating component 7 is disposed inside the material cylinder 1.

[0028] The stop cover 5 has a pressure rod 8 at its upper end for closing, and a pressure spring 9 on the pressure rod 8. A pin 10 for the pressure rod is located on the pressure arm 601. The stop cover 5 is rotatably mounted on the discharge pipe 3. The stop cover 5 can be closed by pressing down on it with the pressure rod 8. Compared to springs and other elastic components, using the pin 10 in conjunction with the pressure rod 8 to press down on the stop cover 5 provides a better pressing effect. Furthermore, springs and other elastic components are easily deformed due to frequent use, resulting in poor reset and causing problems such as slow closing speed and incomplete closure of the stop cover 5. Preferably, the pin 10 is adjustable and mounted on the pressure arm 601. The pressing effect can be controlled by adjusting the degree of pressure applied by the pin 10, allowing the stop cover 5 to more tightly block the discharge port 4 and prevent beads from falling out.

[0029] The upper end of the material cylinder 1 is provided with a cover plate 15, and the cover plate 15 has an inlet 16 for inserting the bead-passing rod of the guide bead rod. One end of the cover plate 15 is hinged to the mounting bracket 18 and cooperates with the material cylinder 1; the discharge pipe 3 provided at the bottom of the feeding container 2 is installed on the cover plate 15; the bottom of the feeding container 2 has a discharge port connected to the discharge pipe 3. The driving pressure component 6 and the stop bottom cover 5 are integrally set on the discharge pipe 3, which can be installed or disassembled as a whole, which is very convenient and more efficient. As shown in the figure, the cover plate 15 has a groove 14 to facilitate the overall disassembly of the driving pressure component 6.

[0030] The rotating component 7 is a concentric shaft mounted on the barrel and concentric with the barrel, or a concentric shaft mounted on the propeller and concentric with the propeller (not shown in the figure). The concentric shaft is provided with a drive protrusion 17 that can rotate with the barrel and periodically engage with the drive rod. By directly mounting the rotating component 7 on the concentric shaft of the barrel or propeller, which is located on the drive shaft 19 of the barrel or propeller and rotates together with the drive shaft, no separate power structure is required, saving costs and simplifying the structure.

[0031] As one approach (not shown in the figure, but existing technology can be used), the barrel 1 is equipped with a propeller that drives the flow of beads inside the barrel 1. The barrel 1 is statically mounted on the mounting frame 18. The bottom of the barrel is provided with a bead drop hole. The upper end of the bead guide rod is placed in the bead drop hole. By rotating the propeller, the flowing beads are made to pass through the upper end of the bead guide rod by probability. In this approach, the rotating component 7 can be set on the propeller.

[0032] Alternatively, the inside of the barrel 1 is empty, and the upper end of the guide rod is placed inside the barrel 1 to form the bead-passing end. The rotation of the barrel 1 drives the movement of the beads inside the barrel 1, and the beads pass through the bead-passing end of the guide rod 2 placed inside the barrel 1 by chance. At this time, the rotating component 7 can be set on the concentric axis of the barrel, that is, on the drive shaft 19 that drives the barrel 1 to rotate, and rotates with the drive shaft.

[0033] The driving arm 601 is rotatably mounted on the discharge pipe 3 at its center. One end of the driving arm is connected to the transmission rod 603, and the other end is connected to the discharge pipe 3 via a tension spring 11. The tension spring 11 is used to fix the position of the driving arm 601, so that the driving arm 601 presses down on the stop cover 5 to close the stop cover 5. The drive rod 602 is a bent rod, with one end connected to the transmission rod 603 and the other end engaging with the drive protrusion 17.

[0034] When the driving protrusion 17 disengages from the driving rod 602, the pin of the driving arm 601, driven by the tension spring 11, presses down on the pressure rod, causing the stop cover 5 to close; the rotating part 7 rotates counterclockwise (as shown in the image). Figure 4 (Using the top view as a reference) Drive the drive protrusion 17 to rotate. The drive protrusion 17 cooperates with the drive rod 602 to push the drive rod 602 to swing. The drive rod 602 drives the drive arm 601 to rotate through the transmission rod 603, so that the end of the drive arm 601 with the pin 10 is lifted. Under the drive of the drive spring 9, the pressure rod disengages from the stop cover 5, and the stop cover 5 rotates and opens.

[0035] The rotating component 7 periodically drives the bottom cover 5 to open and close, which can intermittently and automatically supply beads into the barrel and automatically adapt to the consumption of beads in the barrel.

[0036] The discharge port 4 is equipped with a buffer connector 12 that mates with the stop cover 5 for cushioning. The buffer connector 12 consists of several circumferentially arranged spring pieces. Preferably, the upper end of the stop cover 5, where it mates with the buffer connector, has an arc surface. When the stop cover 5 is closed, it contacts the buffer connector 12, driving the buffer connector to expand outwards, preventing the beads from getting stuck in the discharge port 4. When the stop cover 5 is open, the buffer connector 12, under elastic action, instantly contracts, providing power for the beads to fall, making the fall smoother. Additionally, the buffer connector also acts as a buffer, reducing wear from the opening and closing of the stop cover 5.

[0037] The lower end of the material cylinder 1 is equipped with a drive mechanism 13 for rotating the material cylinder 1. The drive mechanism 13 includes a drive motor 1301, a first gear 1302 mounted on the drive motor, and a drive shaft 19 for rotating the material cylinder. A second gear 1303 is mounted on the drive shaft 19, and a synchronous belt (not shown in the figure) is provided between the first and second gears. The drive motor 1301 drives the first gear 1302 to rotate, which in turn drives the second gear 1303 to rotate via the synchronous belt, thereby driving the drive shaft 19 to rotate, and causing the rotating component 7 to rotate.

[0038] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
