Description

Technical Field

[0001] This utility model relates to the field of rebar feeding technology, specifically a rebar straight thread sleeve feeder. Background Technology

[0002] The straight threaded sleeve for reinforcing bars is a connector used to connect reinforcing bars and has an internal thread corresponding to the threaded end. The construction process involves processing the ends of the reinforcing bars into straight threads using a rolling process, and then connecting the two reinforcing bars with the corresponding connecting sleeve. It has the advantages of high connection strength, stable and reliable connection quality, convenient construction, and fast connection speed, and therefore has been widely used.

[0003] In the existing rebar straight thread sleeve feeder, the rebar needs to be placed inside, and then the feeder moves the rebar. The rebar is then processed into straight threads by a rolling process and connected using a connecting sleeve.

[0004] However, when feeding the reinforcing bars, the bars are prone to displacement and jumping due to their own stress or external interference, which causes the ends of the reinforcing bars and the sleeve to be out of axial direction, making it inconvenient to connect them. This solution is not good at guiding the reinforcing bars. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rebar straight thread sleeve feeder, which solves the problem that rebars are prone to offset and jumping due to their own stress or external interference during feeding, resulting in the rebar ends and sleeves not being on the same axis, making connection inconvenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rebar straight thread sleeve feeder, comprising an installation frame, a sealing cover fixedly installed on the top of the installation frame, a reducer fixedly installed on the surface of the sealing cover, an input end of the reducer connected to a motor, and an output end driving a feeding roller inside the installation frame via a gear set, a positioning ring fixedly installed at one end of the installation frame, a guide assembly fixedly installed inside the positioning ring, an arc-shaped cover fixedly installed on one side inside the installation frame, and a cleaning pad fixedly installed inside the arc-shaped cover;

[0007] The guide assembly includes arc-shaped plates fixedly installed on both sides inside the positioning ring. A positioning block is installed inside the arc-shaped plate. Telescopic rods are fixedly installed on both sides of the surface of the positioning block. A spring is sleeved on the surface of the telescopic rod. A clamping plate is fixedly installed at one end of the telescopic rod.

[0008] In one specific embodiment, a limiting block is fixedly installed at one end of the telescopic rod. The diameter of the limiting block is larger than the diameter of the spring. One end of the spring is fixedly installed on the back of the limiting block. The limiting block facilitates the installation of the spring by personnel, making it a single unit.

[0009] In one specific embodiment, a limiting ring is fixedly installed in the middle of the surface of the arc-shaped plate. The diameter of the limiting ring is larger than the inner diameter of the positioning ring. The design of the limiting ring improves the service life of the arc-shaped plate.

[0010] In one specific embodiment, threaded grooves are provided at the four corners of the sealing cover surface, and positioning bolts are threaded inside the threaded grooves. The positioning bolts facilitate the installation of the sealing cover by personnel, thereby improving the efficiency of the installation of the sealing cover.

[0011] In one specific embodiment, support feet are fixedly installed at the four corners of the bottom of the mounting frame. The surface of the support feet is covered with rubber pads to improve stability. The design of the rubber pads on the support feet improves the stability of the feeder when feeding materials.

[0012] In one specific embodiment, the back of the cleaning pad is arc-shaped, and the size of the back of the cleaning pad is adapted to the size of the inside of the arc-shaped cover. The arc shape facilitates the installation and replacement of the cleaning pad by personnel.

[0013] In one specific embodiment, the cleaning pad is a detachable structure, and its inner surface is provided with staggered raised textures.

[0014] In one specific embodiment, the inner surface of the clamping plate is covered with a wear-resistant rubber layer with a thickness of mm.

[0015] Compared with the prior art, this utility model provides a rebar straight thread sleeve feeder, which has the following beneficial effects:

[0016] In the technical solution disclosed in this utility model, by using the installation frame, guide component, arc cover and cleaning pad, during use, the personnel place the steel bar inside the installation frame, and then the feeder will move the steel bar. When the steel bar moves, the cleaning pad inside the installation frame will clean the dust on the surface of the steel bar, and the guide component will guide the steel bar to ensure that the steel bar enters the sleeve processing area accurately along the preset trajectory, avoiding the phenomenon of deviation, jumping and other phenomena caused by the steel bar's own stress or external interference.

[0017] With the guide component set by this utility model, during use, after the reinforcing bar passes through the installation frame, it will enter the interior of the positioning ring and move forward through the arc plate. When it moves between the clamping plates, the reinforcing bar will squeeze the clamping plate, and the telescopic rod on the back of the clamping plate will also squeeze. After the telescopic rod is squeezed, the spring will extend and retract accordingly. The spring will drive the telescopic rod to rebound, and the telescopic rod will drive the clamping plate to move towards the center synchronously. The clamping plate clamps and guides the reinforcing bar, improving the accuracy of the reinforcing bar trajectory. Attached Figure Description

[0025] Figures 1-4 In one embodiment of this utility model, a rebar straight thread sleeve feeder includes an installation frame 1, a sealing cover 2 fixedly installed on the top of the installation frame 1, a reducer 3 fixedly installed on the surface of the sealing cover 2, a positioning ring 4 fixedly installed at one end of the installation frame 1, a guide component 5 fixedly installed inside the positioning ring 4, an arc-shaped cover 6 fixedly installed on one side inside the installation frame 1, and a cleaning pad 7 fixedly installed inside the arc-shaped cover 6.

[0026] The specific problem addressed in this embodiment is to solve the issue that during the feeding of reinforcing bars, deviation and jumping are easily caused by their own stress or external interference, resulting in the end of the reinforcing bar and the sleeve not being on the same axis, making connection inconvenient. This utility model utilizes the setup of an installation frame 1, a guide component 5, an arc-shaped cover 6, and a cleaning pad 7. During use, personnel place the reinforcing bar inside the installation frame 1, and then the feeder moves the reinforcing bar. As the reinforcing bar moves, the cleaning pad 7 inside the installation frame 1 cleans the dust on the surface of the reinforcing bar, and the guide component 5 guides the reinforcing bar, ensuring that it accurately enters the sleeve processing area along a preset trajectory, avoiding deviation and jumping caused by the reinforcing bar's own stress or external interference.

Tests showed that the offset of the rebar end was ≤0.5mm, and the sleeve connection qualification rate was increased to 98%. In this specific embodiment, during use, after the rebar passes through the installation frame 1, it will enter the interior of the positioning ring 4 and move forward through the arc plate 51. When it moves between the clamping plates 55, the rebar will squeeze the clamping plates 55, and the telescopic rod 53 on the back of the clamping plate 55 will also be squeezed. After the telescopic rod 53 is squeezed, the spring 54 will extend and retract accordingly. The spring 54 will drive the telescopic rod 53 to rebound, and the telescopic rod 53 will drive the clamping plate 55 to move towards the center in sync. The clamping plate 55 clamps and guides the rebar, improving the accuracy of the rebar trajectory.
