Those skilled in the art can obtain other design schemes and drawings based on these drawings without creative effort.

[0016] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them.

Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0017] Reference Figures 1 to 2 The first aspect of the present invention will be described; The first aspect of this utility model provides a feeding device, comprising: 100 racks; The feeding track is inclinedly arranged on the frame 100; A hopper 500 is disposed on the feeding track and is used to store hoses; A swing device is installed on the side wall of the hopper 500, and the swing device is used to control automatic feeding; An air blowing assembly, disposed at the lower end of the feed track, is used to remove dust from the hose.

[0018] The feeding device of this utility model can automatically control the feeding and the feeding rate by setting an automatic swing device; by setting an air blowing component, it can clean and remove dust from the inside of the material during the feeding process, reducing secondary pollution of the material during the feeding process.

[0019] Specifically, the feeding track includes a base 210, a fixed baffle 220, a horizontal limiting device, and a vertical limiting device; the base 210 is inclinedly mounted on the frame 100; the vertical limiting device is provided at the downward inclined end of the base 210; the fixed baffle 220 and the horizontal limiting device are respectively provided on both sides of the top surface of the base 210; the vertical limiting device is used to limit the position of the hose in the direction perpendicular to the top surface of the base 210; the horizontal limiting device is used to limit the position of the hose in the width direction of the top surface of the base 210.

[0020] In this embodiment, a rectangular metal plate (e.g., aluminum alloy or stainless steel) is used as the base 210. To achieve the inclined setting, one side of the base 210 is inclinedly fixed to the support column of the frame 100 by bolts or welding, so that the base 210 forms an inclination angle of about 15° to 30° with the horizontal plane. The fixed baffle 220 is a long strip of metal plate, which is vertically fixed to one edge of the top surface of the base 210 by welding or bolting, forming a fixed sidewall of the hose conveying channel. The horizontal limiting device is installed on the other side of the top surface of the base 210, opposite to the fixed baffle 220. The vertical limiting device is installed at the downward inclined end of the base 210. The hose is placed in the inclined channel formed by the base 210, the fixed baffle 220 and the horizontal limiting device. Under the action of gravity, the hose will automatically slide downward along the inclined base 210. The horizontal limiting device ensures that the channel width is slightly larger than the hose diameter by adjusting the distance between itself and the fixed baffle 220, thereby preventing the hose from shifting left or right, tipping over or getting stuck during the sliding process; the vertical limiting device ensures that only a single hose can pass under it by adjusting the height between itself and the top surface of the base 210, preventing multiple hoses from stacking or jumping over, and ensuring the orderly feeding. The feeding device uses gravity as its power source, has a simple structure, low failure rate, and low maintenance cost. With adjustable limits in both horizontal and vertical directions, it can easily adapt to hoses of different diameters, improving the equipment's versatility and flexibility. Clear limits ensure the hose's stable posture during transport, effectively avoiding problems such as jamming and clogging, and improving feeding efficiency and stability.

[0021] Specifically, the horizontal limiting device includes an adjustable baffle 310, an adjustable rod 320, a push rod screw 330, and a horizontal limiting support 340. The horizontal limiting support 340 is fixed on the base 210. The front of the horizontal limiting support 340 has a U-shaped groove, and the side of the horizontal limiting support 340 has a threaded hole communicating with the U-shaped groove. One end of the adjustable rod 320 is inserted into the U-shaped groove and is tightened and fixed by the push rod screw 330 passing through the threaded hole. The other end of the adjustable rod 320 is fixedly connected to the adjustable baffle 310, and the adjustable baffle 310 is parallel to the fixed baffle 220. By loosening the push rod screw 330, the adjustable rod 320 can move along the length direction of the U-shaped groove, thereby adjusting the horizontal distance between the adjustable baffle 310 and the fixed baffle 220.

[0022] In this embodiment, the horizontal limiting support 340 is a metal component, fixed to the base 210 by bolts. A U-shaped groove with an upward opening is machined on its front side (the side facing the fixed baffle 220). A threaded hole is machined laterally on one side wall of the U-shaped groove, communicating with the interior of the U-shaped groove. The adjustable rod 320 is a round or square rod, one end of which passes through the U-shaped groove. The top rod screw 330 is a bolt with a handle, screwed into the threaded hole on the side of the horizontal limiting support 340. When tightened, the end of the top rod screw 330 presses against the adjustable rod 320 located in the U-shaped groove, thus fixing the adjustable rod 320 in its current position. The adjustable baffle 310 is a long strip of metal plate, its length parallel to the fixed baffle 220. The surface of the adjustable baffle 310 is fixedly connected to the other end of the adjustable rod 320 by welding or bolts.

[0023] When the channel width needs to be adjusted to accommodate hoses of different diameters, the operator first rotates the top rod screw 330 to loosen its end from the adjustable rod 320. At this time, the adjustable rod 320 gains freedom within the U-groove and can move freely along the length of the U-groove (i.e., perpendicular to the fixed baffle 220). The operator moves the adjustable rod 320, causing the adjustable baffle 310 to move closer to or further away from the fixed baffle 220 until the distance between the two reaches the required width. Then, the operator rotates the top rod screw 330 so that its end presses against the adjustable rod 320, generating sufficient friction to firmly lock the adjustable rod 320 within the U-groove, thereby fixing the position of the adjustable baffle 310. The horizontal limiting device is designed so that the width can be adjusted by turning the top rod screw 330. The operation is simple and quick and does not require complicated tools. The U-shaped groove provides stable guidance. With the tightening force of the top rod screw 330, relatively accurate positioning can be achieved. Once fixed, the adjustable baffle 310 is not easy to loosen during operation, ensuring the reliability of the limit.

[0024] Specifically, the vertical limiting device includes a baffle 410, a grooved metal part 420, a fastening screw 430, and a vertical limiting support 440. The vertical limiting support 440 is fixed on the base 210 and has a threaded hole. The grooved metal part 420 has an elongated groove and is bolted to the vertical limiting support 440 by the fastening screw 430 passing through the elongated groove. The grooved metal part 420 is fixedly connected to the baffle 410. The baffle 410 is parallel to the base 210. By loosening the fastening screw 430, the grooved metal part 420 can be moved up and down, thereby adjusting the vertical distance between the baffle 410 and the top surface of the base 210.

[0025] In this embodiment, the vertical limiting support 440 can be an L-shaped or block-shaped metal bracket, which is fixed to the end of the base 210 by bolts. One or more threaded holes are machined on its vertical surface perpendicular to the base 210. The channel-shaped metal part 420 is a metal plate with an elongated through hole (long slot), and the length direction of the elongated slot is vertical. The fastening screw 430 is usually a combination of a bolt and a nut. The bolt passes through the elongated slot on the channel-shaped metal part 420 and is then screwed into the threaded hole on the vertical limiting support 440. The baffle 410 is a small metal sheet or plate with its plane parallel to the top surface of the base 210. The baffle 410 is fixed to the side of the channel-shaped metal part 420 facing the inside of the feeding channel by welding or bolts. When the height of the baffle 410 needs to be adjusted, the operator loosens the fastening screw 430 (nut), so that the channel-shaped metal part 420 is no longer pressed tightly against the vertical limit support 440. At this time, the channel-shaped metal part 420 can move relative to the fastening screw 430 along the length direction of the elongated groove (i.e., the vertical direction). The operator moves the channel-shaped metal part 420 up and down, causing the baffle 410 to rise and fall until the distance between the bottom surface of the baffle 410 and the top surface of the base 210 reaches the required height (usually slightly larger than the diameter of a hose, ensuring that only one hose can pass through). Then, the fastening screw 430 is tightened to securely lock the channel-shaped metal part 420 and the baffle 410 in the new position. By adjusting the height of the baffle 410, the vertical limiting support 440 cooperates with the horizontal limiting device to adapt to hoses of different specifications. The vertical limiting support 440 uses elongated holes and bolts to achieve sliding and fixing, which is simple in principle and reliable in operation. By controlling the height, it can effectively prevent the hose from stacking or jamming at the outlet, ensuring that only one workpiece is output at a time, thus guaranteeing the accuracy of subsequent processes.

[0026] Specifically, the swing device includes a swing baffle 610, a drive shaft 650, a first swing arm 630, a second swing arm 640, and an eccentric shaft motor 620; a through hole is formed on the side wall of the hopper 500; the first end of the drive shaft 650 passes through the through hole and is connected to the swing baffle 610; the second end of the drive shaft 650 is connected to the second end of the second swing arm 640; the eccentric shaft motor 620 is fixed on the frame 100, the output end of the eccentric shaft motor 620 is hinged to one end of the first swing arm 630, and the second end of the first swing arm 630 is connected to the... The first end of the second swing arm 640 is hinged; when the eccentric shaft motor 620 is working, its output end rotates eccentrically, driving the first swing arm 630 to swing back and forth, thereby driving the second swing arm 640, which is hinged to the first swing arm 630, to swing back and forth, so that the transmission shaft 650 and the swing baffle 610, which are connected to the second swing arm 640, rotate back and forth along the axis of the transmission shaft 650, thereby controlling the lower end of the swing baffle 610 to swing away from or near the top surface of the base 210 of the feeding track, so as to release or block the hoses in the hopper 500 one by one.

[0027] In this embodiment, the swing baffle 610 is a rotatable baffle located near the discharge port of the hopper 500; the transmission shaft 650 is a metal shaft, one end of which is supported by a bearing or bushing on the side wall of the hopper 500 and is connected to the swing baffle 610 via transmission (e.g., through a keyway, pin, or tight fit); the first swing arm 630 and the second swing arm 640 are two rigid metal rods or plates, serving as an intermediate transmission mechanism; the rotation center of the output shaft of the eccentric shaft motor 620 (or an eccentric pin on the motor shaft) does not coincide with the center of the motor rotor, resulting in an eccentricity; the eccentric shaft motor 620 body is fixed on the frame 100; When the eccentric shaft motor 620 is energized, it rotates, and its eccentric output end performs circular motion. One end of the first swing arm 630 is hinged to the eccentric output end of the motor. When the eccentric end performs circular motion, it drives the other end of the first swing arm 630 to reciprocate left and right (or back and forth) around the hinge point. The other end of the first swing arm 630 is hinged to one end of the second swing arm 640. The swinging of the first swing arm 630 pushes and pulls the second swing arm 640, causing the second swing arm 640 to also reciprocate. The other end of the second swing arm 640 is connected to the outer end of the transmission shaft 650. The swinging of the second swing arm 640 drives the transmission shaft 650 to reciprocate around its own axis (rotating forward at a certain angle, then backward). (Rotating at a certain angle); the rotation of the drive shaft 650 directly drives the connected swing baffle 610 to reciprocate at the outlet of the hopper 500, causing the swing baffle 610 to reciprocate between two extreme points, which refer to the farthest positions of the swing baffle 610 at both ends of the swing. When the swing baffle 610 is at the lowest position, it is in a blocking state, at which time the vertical distance between the swing baffle 610 and the feeding track is small, and the material cannot pass through. When the swing baffle 610 is at the highest position, it is in an open state, at which time the vertical distance between the swing baffle 610 and the feeding track increases, allowing the material to pass through. By controlling the speed and start / stop of the motor, the frequency and quantity of feeding can be precisely controlled. Compared to pure gravity feeding, the swing device can achieve intermittent, quantitative, and orderly feeding, improving the accuracy and efficiency of automated production lines. Utilizing the eccentric shaft motor 620 and the double swing arm mechanism, the required reciprocating swing can be achieved in a small space. The structure is compact, and the mechanical transmission structure is reliable and durable, enabling it to adapt to long-term stable operation in industrial environments.

[0028] Specifically, the air blowing assembly includes a nozzle 710, a pipe 720, and an air supply device 730; the air supply device 730 is fixed on the frame 100 and is connected to the nozzle 710 through the pipe 720; the nozzle 710 is fixed to the lower inclined end of the base 210, and the air outlet of the nozzle 710 faces the fixed baffle 220; the air supply device 730 provides compressed air to the nozzle 710 through the pipe 720, and when the hose is delivered in front of the air outlet of the nozzle 710, the airflow is ejected from the nozzle 710 to remove dust or debris from the hose.

[0029] In this embodiment, the air supply device 730 can be a small air compressor, which is responsible for providing compressed air at a certain pressure; the pipe 720 is a high-pressure hose or a rigid metal pipe, used to transport compressed air; the nozzle 710 is a metal or plastic part with a small nozzle hole, which can convert the pressure energy of compressed air into high-speed airflow; the nozzle 710 is fixed to the end of the base 210, and its air outlet faces the side of the fixed baffle 220. Compressed air generated by the air supply device 730 is delivered to the nozzle 710 through the pipe 720. The nozzle 710 is precisely aligned with one side of the fixed baffle 220. When a hose is delivered to this position (which can be detected and triggered by a sensor or synchronized with the movement of the swing device), compressed air is ejected at high speed from the small nozzle orifice of the nozzle 710. The high-speed airflow blows across the inner and outer surfaces of the hose, blowing away dust, chips, oil and other debris attached to it, thus achieving the purpose of cleaning.

[0030] By using an air blowing assembly to remove impurities from the surface of the hose, the material can be cleaned and dust removed during the feeding process, reducing secondary contamination and effectively protecting subsequent processing equipment (such as assembly, welding, and testing equipment), thus avoiding malfunctions or product quality problems caused by impurities.
