Description

Technical Field

[0001] This utility model relates to the field of cable tie production technology, and in particular to a deburring device for the ends of plastic cable ties. Background Technology

[0002] Cable ties, also known as wire ties, cable bundles, or locking straps, are straps used to bundle things together. They are generally classified by material, such as nylon cable ties, stainless steel cable ties, and powder-coated stainless steel cable ties. By function, they are classified as ordinary cable ties, removable cable ties, label cable ties, fixed locking cable ties, pin-type cable ties, heavy-duty cable ties, etc. However, plastic cable ties often develop burrs on their edges during the manufacturing process. These burrs frequently cause the cable tie ends to jam against the head during later use, affecting its usability. Therefore, a deburring device is needed to remove these burrs.

[0003] Traditional deburring devices for plastic cable ties have several shortcomings. First, they cannot automatically load and unload plastic cable ties, making them unsuitable for deburring batches of cable ties with inconsistent end shapes. Second, they cannot keep the inner hole of the end facing upwards, resulting in incomplete deburring of the inner wall and edges of the end. Therefore, it is necessary to optimize and improve traditional deburring devices for plastic cable ties. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems in traditional technology and provide a device for deburring the ends of plastic cable ties.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-6As shown, this embodiment is a deburring device for the ends of plastic cable ties, including a mounting frame 1, a feeding hopper 2, a lower circulating conveyor belt 3, an upper circulating pressure belt 4, rollers 5, a gear set 6, a limiting plate 7, a crossbeam 8, and a dry ice spray pipe 9. There are two mounting frames 1 arranged side-by-side, with the feeding hopper 2 fixedly installed between the two mounting frames 1. The lower circulating conveyor belt 3 is located below the feeding hopper 2, and the upper circulating pressure belts 4 are located on both sides of the feeding hopper 2. Each of the lower circulating conveyor belt 3 and the upper circulating pressure belt 4 has multiple rollers 5 installed inside to drive their rotation. The outer ends of a pair of opposing rollers in the lower circulating conveyor belt 3 and the upper circulating pressure belt 4 are connected by a gear set 6, which consists of two mutually closed gears.

[0028] In this embodiment, the outer surface of the lower circulating conveyor belt 3 is evenly distributed with strip-shaped conveying grooves 10 for holding the strip portion 121 of the plastic cable tie 12. The upper belt body and the lower belt body of the lower circulating conveyor belt 3 are in contact with each other. The thickness of the strip-shaped conveying groove 10 is equal to the thickness of the strip portion 121 of the plastic cable tie 12, the width of the strip-shaped conveying groove 10 is 1.2 to 1.4 times the width of the strip portion 121 of the plastic cable tie 12, and the length of the strip-shaped conveying groove 10 is equal to the length difference between the strip portion 121 and the end portion 122 of the plastic cable tie 12.

[0029] In this embodiment, several sets of limiting plates 7 are installed between the two mounting frames 1. The limiting plates 7 are provided with anti-deviation grooves 11 that match the width of the belt in the lower circulating conveyor belt 3 or the upper circulating pressing belt 4. The depth of the anti-deviation grooves 11 is less than or equal to the thickness of the belt in the lower circulating conveyor belt 3 or the upper circulating pressing belt 4.

[0030] In this embodiment, the lower circulating conveyor belt 3 and the upper circulating pressing belt 4 are each limited by the limiting plate 7 and the corresponding side mounting frame 1, leaving a deburring area to expose the middle end 122 of the plastic cable tie 12. Two dry ice spray pipes 9 located directly above the deburring area are installed between the two mounting frames 1 through the crossbeam 8.

[0031] In this embodiment, the spacing between the two mounting frames 1 is equal to the total length of the plastic cable ties 12.

[0032] In this embodiment, the upper end of the feeding hopper 2 is provided with a feeding inlet, and the lower end of the feeding hopper 2 is provided with a feeding outlet. The length of the feeding outlet is equal to the overall length of the plastic cable tie 12, and the width of the feeding outlet is 2 to 3 times the width of the strip portion 121 in the plastic cable tie 12.

[0033] In this embodiment, the two upper circulating pressure belts 4 have different lengths, with the one located below the crossbeam 8 being longer. The longer upper circulating pressure belt 4 mainly cooperates with the lower circulating conveyor belt 33 to clamp and displace the plastic cable ties 12. The shorter upper circulating pressure belt 4 mainly provides internal thrust to prevent the material at the discharge point from shifting outward due to compression.

[0034] In this embodiment, an anti-slip structure is provided between the roller 5 and the lower circulating conveyor belt 3 or the upper circulating pressure belt 4. Anti-slip grooves are provided near both ends of the roller 5, and two rings of anti-slip protrusions that cooperate with the anti-slip grooves are provided on the inner side of the lower circulating conveyor belt 3 or the upper circulating pressure belt 4.

[0035] In this embodiment, the outer end of at least one roller 5 is connected to the output shaft of the drive motor via a coupling, and the drive motor is mounted on the adjacent mounting frame 1.

[0036] In this embodiment, the dry ice spray pipe 9 is externally connected to a dry ice cleaning machine that can supply dry ice to it.

[0037] A specific application of this embodiment is as follows: This device mainly consists of an installation frame 1, a feeding hopper 2, a lower circulating conveyor belt 3, an upper circulating pressure belt 4, a roller 5, a gear set 6, a limiting plate 7, a crossbeam 8, and a dry ice spray pipe 9. The lower circulating conveyor belt 3 and the two upper circulating pressure belts 4 together form a feeding area that facilitates the feeding of material from the feeding hopper 2. The outer surface of the lower circulating conveyor belt 3 is evenly distributed with strip-shaped conveying grooves 10 for holding the strip portion 121 of the plastic cable tie 12. The lower circulating conveyor belt 3 and the upper circulating pressure belt 4 on one side are used to clamp and convey the plastic cable tie 12. The end 122 of the plastic cable tie 12 is displaced along the deburring area, and its inner hole is vertical during the displacement process. Dry ice is sprayed downward by the dry ice spray pipe 9, which can thoroughly remove the burrs on the inner hole wall and edge of the end of the plastic cable tie.
