Description

Technical Field

[0001] The utility model relates to the technical field of binding strap production, in particular to a binding strap feeding device. Background Art

[0002] As a common connection, fixing or packaging material, strapping is widely used in the packaging and transportation of various products. With the development of automation technology, the requirements for the continuity and stability of strapping supply are becoming higher and higher. However, the traditional strapping feeding method often has problems such as unstable feeding and low efficiency, which makes it difficult to meet the needs of efficient production.

[0003] In the current related technology, the strapping is usually directly transferred from the feed assembly to the point of use without intermediate storage and buffering. This method can easily lead to excessive pressure on the feed assembly in a high-speed, high-load production environment, thus affecting the stability and efficiency of the entire production line. In addition, due to the lack of a buffer mechanism, once the feed assembly fails or is delayed, the entire production line may face the risk of shutdown. Utility Model Content

[0006] The feeding assembly is located at one side of the feeding port and is used to convey the strap to the feeding port. The strap passes downward from the feeding port around the belt winding wheel and is then led out through the discharging port to feed the material.

[0007] In a specific embodiment, the feeding assembly includes two conveying rollers arranged vertically, and a feeding space allowing the strap to pass through is formed between the two conveying rollers. The conveying rollers are driven to rotate by a rotary drive mechanism to convey the strap in the feeding space to the feeding port.

[0008] A guide roller is installed at the discharge port.

[0009] Furthermore, the guide roller and the belt winding wheel are respectively installed in a limiting groove, and a limiting space is formed between the limiting groove and the guide roller and the belt winding wheel respectively. During operation, the binding belt is inserted into the limiting space.

[0010] In addition, a counterweight block is detachably mounted on the bottom end of the gravity block.

[0011] The surface of the conveying roller is provided with a plurality of anti-skid protrusions.

[0012] In the solution of the present application, after the straps enter from the feed port, the gravity drives the gravity block to descend, and at the same time, it bypasses the belt winding wheel to form a U-shaped storage structure. This design can store longer straps in a limited space, improving storage efficiency.

[0018] Specifically, the support rail 200 can adopt a standard linear rail, and the gravity block 201 is a matching slider therefor; in addition, the support rail 200 can also adopt two parallel cylindrical rails, and the sliders matching the two parallel cylindrical rails are used as the gravity block 201. The gravity block 201 adopts linear bearings or bushings, which are mounted on the two rails, so that the gravity block 201 can slide vertically on the two parallel rails; the double-rod structure can provide better support and guidance, and reduce shaking and deviation.

[0019] The feeding assembly is located at one side of the feeding port 203 and is used to feed the strap to the feeding port 203. The strap goes down from the feeding port 203 around the belt winding wheel 202 and then is led out through the discharging port 204. In a possible embodiment, the feeding assembly may include an electric feeding roller and a tension control device.

[0020] After the strap enters from the feed port 203, it drives the gravity block 201 downward under the action of gravity, and at the same time, it passes around the belt winding wheel 202 to form a U-shaped storage structure. This design can store longer straps in a limited space, improving storage efficiency. At the same time, it can reduce the pressure of the feed assembly and improve the stability and reliability of the system.

[0021] When the feeding is interrupted briefly, the straps in the storage assembly can continue to be supplied, and the gravity block 201 will slowly rise. After the feeding is resumed, the gravity block 201 will slowly descend again to replenish the stored straps. This is beneficial to improving the continuity of the production line and reducing the downtime caused by feeding interruption.

[0022] In another possible embodiment, the feeding assembly includes two conveying rollers 100 arranged vertically, a feeding space for allowing the strap to pass through is formed between the two conveying rollers 100, and the conveying rollers 100 are driven to rotate by a rotary drive mechanism 101, so as to convey the strap in the feeding space to the feeding port 203. A plurality of anti-slip protrusions are provided on the surface of the conveying rollers 100.

[0023] A guide roller 205 is installed at the discharge port 204 .

[0024] The conveying roller 100 may be made of high-strength rubber or polyurethane material. The conveying roller 100 may be provided with spiral or herringbone patterns with a protrusion height of 1-2 mm to increase friction.

[0025] The rotation driving mechanism 101 may be a stepper motor or a servo motor in combination with a reducer.
