Description

[Technical Field]

[0001] The present invention relates to the field of wire reels and relates to wire reels. [Background technology]

[0002] A rebar binding machine cannot bind rebars unless a wire reel is installed during use. Currently, an identifier (e.g., a two-dimensional code, a barcode, etc.) that stores wire reel information is provided on the side plate of the wire reel, but providing the wire reel identifier on the side plate makes it difficult to identify the identifier. For example, Chinese Appearance Patent "CN202130621421.7" discloses a take-up reel for a binding machine (with a two-dimensional code identifier), and as shown in FIG. 1, a two-dimensional code is provided on the side plate of the take-up reel. As can be seen, in order to identify the information in the two-dimensional code, an identification device for identifying the two-dimensional code must be connected to the binding machine.

[0003] However, in the above-mentioned conventional technology, even if the binding machine is equipped with an identification device that identifies the two-dimensional code, the two-dimensional code is difficult to accurately identify because after the binding machine pulls the wire and moves the wire take-up reel to rotate a certain number of turns, the two-dimensional code on the wire take-up reel does not necessarily remain in its initial position, making it difficult for the identification device to identify the two-dimensional code after the wire take-up reel stops rotating. Summary of the Invention [Problem to be solved by the invention]

[0020] To more clearly describe the wire reel of the present invention, the wire reel will be further described below in combination with a strapping machine.

[0021] Referring to FIG. 2, the rebar binding machine includes a case 1, a wire feeding mechanism 2 provided within the case 1, a braking mechanism 3, a wire winding mechanism 4, and a loop forming mechanism 5 provided at the tip of the case 1. A wire reel chamber 111 is provided within the case 1, and the wire reel chamber 111 is used to mount a wire reel 6. The wire feeding mechanism guides and supplies the wire to the loop forming mechanism, which winds the wire around the rebar by guiding it into a circular shape. The wire winding mechanism tightens the wire wound around the rebar, and the braking mechanism brakes the wire reel 6 when the wire feeding mechanism stops feeding the wire. In use, simply installing the wire reel 6 in the wire reel chamber 111 of the rebar binding machine is sufficient to perform the rebar binding operation. It should be noted that in the above structure, the wire reel 6 is not a part of the binding machine. 3 to 7, the case 1 includes a first housing 11 and a second housing 12 hingedly connected to each other, the first housing 11 having a groove structure, the groove space of which is a wire reel chamber 111, and the second housing 12 rotatably covering the first housing 11, thereby forming a sealed wire reel chamber 111. The first housing 11 is provided with a first connecting hole 112 that penetrates into the wire reel chamber 111, and a limiting groove installed coaxially with the first connecting hole 112 is provided on the inner wall of the first housing 11, and a connecting tube 7 is further connected to the position of the first connecting hole 112. The radial cross section of the connecting tube 7 is annular, and from left to right (from the first housing 11 to the second housing 12), the outer wall of the connecting tube 7 includes a connecting portion a 71 and a connecting portion b 72, the diameter of the connecting portion a 71 matches the diameter of the first connecting hole 112, a first locking groove 711 is provided on the left side of the connecting portion a 71, and the diameter of the connecting portion b 72 is larger than the diameter of the first connecting hole 112, and a limiting boss 721 is provided on the right side of the connecting portion b 72. A support ring 73 that matches the connecting portion b 72, a first locking ring 74 and a second locking ring 75 that match the connecting portion a 71, and a C-shaped snap ring 76 that engages with the first locking groove 711 are attached to the outer wall of the connecting tube 7.During assembly, the support ring 73 is fitted onto the b connecting portion 72 until its right side contacts the limiting boss 721, then the second locking ring 75 is fitted onto the right side of the a connecting portion 71, and then the connecting tube 7 is passed through the first connecting hole 112 until the second locking ring 75 is engaged with the limiting groove of the first housing 11 (at this time, the left end of the a connecting portion 71 is exposed to the outer wall of the first housing 11), then the first locking ring 74 is fitted onto the left side of the a connecting portion 71 until its right side contacts the outer wall of the first housing 11, and finally the C-shaped snap ring 76 is engaged with the first locking groove 711 to restrict the left and right movement of the first locking ring 74, so that the connecting tube 7 is stably connected to the first housing 11. In the above structure, the support ring 73 is for supporting the wire reel 6 so that it rotates. Referring to Figure 5, a circular second locking groove 722 is provided on the inner wall of the connecting tube 7, close to the right side, and the second locking groove 722 is for stably fixing the wire reel 6 to the support ring 73. The specific structure for supporting and connecting the wire reel 6 by installing the support ring 73 and the second locking groove 722 will be described below.

[0022] Referring to Figures 8 and 9, the wire reel 6 is composed of an integrally molded shaft tube 61 and two side plates 62 located at both ends of the shaft tube 61, and the outer wall of the shaft tube 61 and the two side plates 62 form a wire winding chamber, and an shaft hole 611 is formed in the center of the shaft tube 61, and a partition section 614 is provided in the shaft hole 611, and one side of the partition section 614 is an anti-counterfeiting detection chamber 612 and the other side of the partition section 614 is a wire head fixing chamber 613. In the above structure, first, the anti-counterfeiting detection chamber 612 is installed independently, so that the anti-counterfeiting identifier and / or the identification device 8 can be installed in the space of the anti-counterfeiting detection chamber 612. After the wire reel 6 is installed in the binding machine, simply aligning the anti-counterfeiting identifier and the identification device 8 to face each other can ensure that the identification device 8 can stably identify the anti-counterfeiting identifier. In contrast to the prior art, where the anti-counterfeiting identifier is mounted on the side panel and the identification device must instantly identify the anti-counterfeiting identifier every time the wire reel rotates, in this embodiment the wire reel is connected to the binding machine and, during use, the identification device 8 can face the anti-counterfeiting identifier. Therefore, even if the binding machine rotates at a relatively slow speed, the identification device can identify the anti-counterfeiting identifier and thereby record the number of turns of the wire. Every time the wire completes one binding, the wire reel stops rotating, at which point the identification device faces the anti-counterfeiting identifier and can identify the anti-counterfeiting identifier, thereby recording the number of times the rebar has been bound to one wire reel. Next, in the prior art, the axial hole 611 is merely for rotating connection to the binding machine, while the above structure performs anti-counterfeiting identification by installing an anti-counterfeiting detection chamber 612 at the position of the axial hole 611, thus improving the space utilization rate of the axial hole 611; finally, the axial hole 611 is divided into a wire head fixing chamber 613 and an anti-counterfeiting detection chamber 612, thus preventing the wire head in the wire head fixing chamber 613 from entering the anti-counterfeiting detection chamber 612, thereby avoiding interference between the wire head and the anti-counterfeiting identifier or identification device 8 in the anti-counterfeiting detection chamber 612.

[0023] The partition 614 of the anti-counterfeiting detection chamber 612 may be a partition plate that closes the axial hole 611. Naturally, a gap may be formed between the partition 614 and the inner wall of the axial hole 611, and may be installed as needed. In this embodiment, the partition 614 is a partition plate that closes the axial hole 611. An anti-counterfeiting identifier is provided in the anti-counterfeiting detection chamber 612 and on the partition 614. The anti-counterfeiting identifier may be attached to the partition or printed on the partition. The anti-counterfeiting identifier may be a two-dimensional code or a barcode. Referring to FIGS. 3-4 and 6, an end cover 13 covering the first connecting hole 112 is screwed to the outer wall of the first housing 11, and an identification device 8 facing the internal cavity of the connecting tube 7 is provided at a position corresponding to the first connecting hole 112 of the end cover 13. In use, when the wire reel is connected to the connecting tube 7, regardless of the position at which the wire reel 6 stops rotating, the identification device 8 can identify the anti-counterfeit identifier through the internal cavity of the connecting tube 7 and the anti-counterfeit detection chamber 612. In the above structure, in a preferred embodiment, the partition plate is installed along the radial direction, so that the identification device 8 can face the anti-counterfeit identifier directly and ensure that the anti-counterfeit identifier can be clearly identified and scanned, thereby improving the accuracy and stability of identifying the anti-counterfeit identifier.

[0024] 8-9, a circular groove 6121 is provided on one side of the anti-counterfeiting detection chamber 612. The circular groove 6121 is concentric with the axial hole 611, with a diameter greater than that of the axial hole 611, and the circular groove is connected to the anti-counterfeiting detection chamber 612. As can be seen from the structure in the figures, the circular groove 6121 and the anti-counterfeiting detection chamber 612 form a countersunk structure, i.e., the anti-counterfeiting detection chamber 612 is located at the bottom of the circular groove 6121. During use, the wire reel 6 is rotatably engaged with the support ring 73 via the circular groove 6121, and the support ring 73 provides support for the wire reel 6. This ingeniously solves the problem of the wire reel and the binding machine not being able to fit loosely after the axial hole is used in the anti-counterfeiting detection chamber 612, and the circular groove is used as a shaft support point, resulting in a simple structure and easy processing.

[0025] To ensure that the wire reel 6 can be stably connected to the support ring 73 after the second housing 12 is opened, the partition plate is provided with a locking bar 6122 extending outward from the anti-counterfeiting detection chamber 612. Specifically, the locking bar 6122 includes an elastic locking bar 6123 and a locking block 6124 provided on the elastic locking bar 6123, and the locking block 6124 is locked into the second locking groove 722 of the connecting tube 7. In this way, when the circular groove of the wire reel 6 is engaged with the support ring 73, the locking block 6124 is also engaged with the second locking groove 722, thereby stably fixing the wire reel 6 to the support ring 73. The provision of the locking bar 6122 overcomes the problem of the wire reel easily coming off due to the use of a circular groove as a shaft support in the present invention, and greatly improves the reliability and stability of the present invention.

[0026] 4, a wire passing passage 6131 is provided between the wire head fixing chamber 613 and the winding chamber, and when a wire is wound around the winding chamber, the wire head is knotted in the wire head fixing chamber 613 through the wire passing passage 6131, thereby fixing the wire head to the wire head fixing chamber 613. Referring to FIGS. 5 and 6, a plurality of first bumps 6132 are provided on the side wall of the wire head fixing chamber 613, one end of each first bump 6132 is close to the partition 614, and a plurality of first bumps are provided on the inner wall of the wire head fixing chamber 613 along the circumferential direction, and a limiting groove is formed between two adjacent first bumps 6132. As shown in FIG. 4, a second bump 121 is provided on the second housing 12, and when the second housing 12 is covered by the first housing 11, the second bump 121 is engaged with the limiting groove and abuts against the first bump 6132, thereby restricting the left-right movement of the wire reel 6, thereby improving the assembly stability and rotational stability of the wire reel 6.

[0027] 8 and 9, brake teeth 621 are uniformly provided on the outer peripheral wall of the side plate 62 approaching the wire head fixing chamber 613, and when the wire feeding mechanism stops wire feeding, the brake lever of the brake mechanism can be engaged with the brake teeth 621 to stop the wire reel 6 from rotating.

[0028] While embodiments of the present invention have been shown and described, those skilled in the art will recognize that changes can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is limited only by the appended claims and their equivalents.
