Description

TECHNICAL FIELD

[0001] The present invention relates to the technical field of binding machines, particularly to a binding machine having a function for identifying wire roll information. BACKGROUND OF THE TECHNOLOGY

[0002] Currently, binding machines are widely used in the field of architecture. The main structure of the binding machine mainly includes a housing, a wire reel, a wire feeding mechanism, a wire guiding structure, a wire cutting mechanism, and a wire winding mechanism. The wire feeding mechanism conveys a binding wire from the wire reel to the wire guiding mechanism. The wire guiding mechanism limits and guides the binding wire, so that the binding wire is wound around the outside of an object to be bound in the shape of a loop. After the binding wire is wound, the wire cutting mechanism cuts the binding wire. Then, the wire winding mechanism twists the binding wire wound around the outside of the object to be bound, so that the object to be bound can be tightly bound by the binding wire.

[0003] Wire reels are products that require replacement in large quantities, so there are many counterfeit and inferior products on the market. To distinguish themselves from counterfeit and inferior products, a wire reel is usually equipped with a QR code for anti-counterfeiting and to store the information of this wire reel. The authenticity and specific information of the wire reel can be clearly identified by scanning the QR code during use. However, existing wire reels have low identification efficiency and poor identification effect after the wire reels are arranged on binding machines.

[0004] For example, Chinese Patent "CN113788177A" discloses a binding machine with a roll information identification device, wherein the roll is provided with an anti-counterfeiting QR code, and the QR code can also be arranged hierarchically. For example, if there are ten roll packs in a box and each pack contains a dozen rolls, it is possible to provide one QR code for each roll, one QR code for each pack of a dozen rolls, and one QR code for each box. When a worker uses a dozen rolls, they can input the setting information of the 12 rolls and the anti-counterfeiting information of each roll into the binding machine by scanning the QR code on this package.In addition, different QR codes are provided on single rolls, dozens of rolls, and roll packs so that people in different positions can code, or after the people in different positions / tasks code the QR codes, it is automatically saved to their cloud file. Through this program setting, the circulation path and usage of a roll can be analyzed. This function is mainly performed by background programs and cloud servers. After the QR code is provided on a roll in the binding machine, artificial identification must be performed. However, this identification mode is inefficient and increases the usage cost of the binding machine.

[0005] Another example is the Chinese design patent "CN307092714S", which discloses a winding roll for a binding machine (with a QR code identifier), where Fig. As can be seen from Figure 1, the QR code is provided on an end plate of the winding roll and is located on an outer side of a rotating shaft of the winding roll. Due to the installation of the winding roll in the binding machine, the position of the QR code continuously changes with the rotation of the winding roll when the binding machine is operating. Therefore, when the rotation of the winding roll stops, it is difficult to identify the QR code because the QR code is not in a fixed position. SUMMARY OF THE PRESENT INVENTION

[0006] In order to solve the problem of the prior art that the QR code on an existing roll has low identification efficiency, has poor identification effect, and is difficult to identify, the present invention provides a binding machine with a function of identifying wire roll information.

[0007] In order to achieve the above-mentioned object, the binding machine with the wire roll information identifying function in the present invention employs the following technical solutions.

[0008] A binding machine with a function of identifying wire roll information is provided, comprising a housing and a wire feeding mechanism, a wire guiding mechanism, a wire cutting mechanism, and a wire winding mechanism arranged in the housing, wherein a roll flap is arranged in the housing, a roll support shaft and an identification device are arranged in the roll flap, and the identification device is arranged in the center of the roll support shaft.

[0009] Furthermore, the identification device is arranged coaxially to the roller support shaft.

[0010] Furthermore, the identification device protrudes from the roll holder shaft.

[0011] Furthermore, a recessed portion is arranged in the center of the roller support shaft in which the identification device is housed.

[0012] Furthermore, a support section is arranged on the roller support shaft.

[0013] Furthermore, a roller locking portion is arranged in the center of the roller support shaft.

[0014] Further, a locking groove which is an annular groove is arranged in the center of the roller support shaft, and the annular groove is the roller locking portion.

[0015] Furthermore, the roller flap comprises a groove arranged on the housing and a cover plate lying on the groove, which is movably connected to the groove.

[0016] Furthermore, a housing locking device is arranged on the housing, and one end of the end plate is hinged to the housing, while the other end of the end plate is equipped with the housing locking device.

[0017] Furthermore, a lighting device is arranged on the roller support shaft.

[0018] Compared with existing binding machines, the binding machine with the wire reel information identification function of the present invention has the following advantageous effects. The reel support shaft is used to support the wire reel, and the hollow space in the center of the wire reel is appropriately mounted on the reel support shaft when in use. When an iron wire is drawn, the wire reel rotates around the reel support shaft.By providing the identification device in the center of the reel support shaft, when the QR code on the wire reel is also provided in its cavity and is located at a position corresponding to the identification device, no matter where the rotation of the wire reel stops, the identification device can scan and read the information of the wire reel on the QR code, thereby ensuring that the QR code can be easily identified and avoiding the problem that the QR code cannot be identified or is not clearly identified when it is located at different positions.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

[0020] In the description of the present invention, the orientation or relationship indicated by the terms "inside," "outside," or the like is an orientation or relationship shown in the drawings, which is used only to describe the present invention and simplify the description. It does not indicate or imply that the specified device or element must have a particular orientation or be constructed and operated in a specific orientation. Therefore, these terms should not be interpreted as limitations on the present invention.

[0021] In the context of the present invention, the terms "assemble," "connect," "fix," or the like are to be understood in a broad sense unless expressly stated and defined otherwise. For example, it may be a fixed connection, a detachable connection, or an integration; or it may be a mechanical connection or an electrical connection; or it may be a direct connection or an indirect connection via an intermediate medium; or it may be an internal communication between two elements or an interaction between two elements, unless expressly defined otherwise. Those skilled in the art can understand the specific meanings of the terms in the present invention according to the specific conditions.

[0022] The technical solutions of the present invention are described below with reference to the Fig. 2-7 are described in more detail.

[0023] A binding machine is provided with the function of identifying wire roll information based on Fig. 2 and includes a housing 1 and a wire feeding mechanism 2, a wire guiding mechanism 3, a wire cutting mechanism (not shown), and a wire winding mechanism 4 arranged in the housing 1. The wire feeding mechanism 2 is configured to feed an iron wire to the wire guiding mechanism 3; the wire guiding mechanism 3 is configured to guide the iron wire into a circular shape for winding it around a rebar; the wire cutting mechanism is configured to cut the iron wire; and the wire winding mechanism 4 is configured to tighten the iron wire wound around the rebar. Of course, some existing tying machines are also equipped with a braking mechanism 5 configured to brake the wire reel 6 when the wire feeding mechanism 2 stops feeding wire.The structures, connection relationships, and operating procedures of the above-mentioned mechanisms are state of the art and are not repeated here.

[0024] As in Fig. 2, a roller shutter 11 is also arranged in the housing 1, and the roller shutter 11 is used to accommodate the wire reel 6. However, it should be noted that the wire reel 6 is not a part of the tying machine, and the wire reel 6 and the iron wire wound around the wire reel 6 are environmental features. In other words, when the tying machine is sold alone, there is no wire reel 6 in the roller shutter 11. During the tying and knotting of a rebar, it is necessary to load the wire reel 6 into the housing 1 to perform the rebar tying process. In order to better describe the structure of the tying machine, this embodiment will be described in combination with the wire reel 6 having the corresponding structure.

[0025] According to Fig. 3-5, an identification device 7 and a roll support shaft 12 for rotatably supporting the wire roll 6 are arranged in the roll flap 11, wherein the identification device 7 is arranged in the center of the roll support shaft 12. A control unit electrically connected to the identification device 7 is also arranged in the housing 1. According to Fig. 6-7, the wire reel 6 includes a molded shaft cylinder 61 and two end plates 62. The two end plates 62 are respectively disposed at the two ends of the shaft cylinder 61. A receiving cavity 63 for receiving an iron wire is formed by an outer peripheral wall of the shaft cylinder 61 and the end plates 62, and the iron wire is wound on the shaft cylinder 61 and disposed in the receiving cavity 63. A hole-shaped structure 64 (i.e., a space in the center of the shaft cylinder 61) is provided on the shaft cylinder 61, and a QR code corresponding to the position of the reel support shaft 12 is provided in the hole-shaped structure 64. The QR code has a code pattern that characterizes the basic information of the wire reel 6, and this code pattern is an encrypted code pattern.During use, when the rotation of the wire reel 6 stops, since the position of the QR code on the wire reel 6 corresponds to the position of the identification device 7, no matter where the rotation of the wire reel 6 stops, the identification device 7 can scan and read the information about the wire reel 6 on the QR code, thereby ensuring that the QR code can be easily identified and avoiding the problem that the QR code cannot be identified or is not clearly identified when it is arranged in different positions.

[0026] As an improvement, a depressed portion 121 is arranged in the center of the roller support shaft 12, and the identification device 7 is arranged in the depressed portion 121. In particular, in the Fig. 3-5, the roller support shaft 12 has a hollow cylindrical structure, and the cavity in the center of the roller support shaft 12 is the above-mentioned recessed portion 121. One end of the roller support shaft 12 is detachably connected to the roller cover 11, while the other end of the roller support shaft 12 rotatably supports the wire reel 6. The identification device 7 is also connected to the roller cover 11 and is located in the cavity in the center of the roller support shaft 12. It can identify the QR code after passing through the cavity in the center of the roller support shaft 12 and the hole-shaped structure 64 of the shaft cylinder 61. By providing the recessed portion 121 on the above-mentioned reel support shaft 12, it can be connected to the wire reel 6, and the identification device 7 can be arranged in the recessed portion 121, so that the identification device 7 can be protected from damage.Furthermore, the structure is simple and easy to assemble. To improve the identification effect of the identification device 7, the identification device 7 is arranged coaxially with the roller support shaft 12 and the hole-shaped structure 64 of the shaft cylinder 61. In this way, the identification device 7 can be directly directed at the QR code, and the identification effect of the QR code can be improved.

[0027] As another alternative solution, the roller support shaft 12 may also be constructed in a columnar manner, and the identification device 7 is disposed on the roller support shaft 12 and protrudes from the roller support shaft 12. By protruding the identification device 7 from the roller support shaft 12, the identification device 7 can be closer to the QR code, thereby shortening the time for identifying the QR code and improving the efficiency of identifying the QR code.

[0028] As an improvement, Fig. 5, a support portion 122 is arranged on the roller support shaft 12, and the support portion 122 is a circular structure mounted on the roller support shaft 12. According to Fig. 6-7, the above-mentioned hole-shaped structure 64 includes an embedding portion 641 arranged on the outer side and a shaft hole 642 arranged on the inner side, which are concentrically arranged and have circular cross sections. The embedding portion 641 has a larger diameter than the shaft hole 642, and the embedding portion 641 is configured in shape and size for the support portion 122. When the wire reel 6 is mounted on the reel cover 11, the embedding portion 641 of the wire reel 6 is rotatably connected to the support portion 122, so that the wire reel 6 can rotate around the reel support shaft 12. The above structure is simple and easy to manufacture and assemble. A further improvement is that a partition plate 65 is arranged in the shaft hole 642, and the QR code is encoded on the partition plate 65.The arrangement of the partition plate 65 can facilitate the arrangement of the QR code in the shaft hole 642.

[0029] In Fig.5, a roller locking portion 123 is disposed at the center of the roller support shaft 12, and the roller locking portion 123 is used to lock the wire roller 6 to prevent the wire roller 6 from falling off after it is mounted on the roller support shaft. In a preferred embodiment, a locking groove is disposed at the center (near the inner wall of the wire roller 6) of the roller support shaft 12, and the locking groove is a circular groove (i.e., the above-mentioned roller locking portion 123). Accordingly, an elastic locking rod 66 is disposed inside the shaft bore 642 of the wire roller 6 on the side near the identification device 7, and a snap-lock block 661 is provided at the end of the elastic locking rod 66.When the wire reel 6 is mounted on the reel cover 11 and the embedding portion 641 is joined to the support portion 122, the snap-lock block 661 on the elastic locking rod 66 is snapped into the locking groove. Due to the locking effect between the snap-lock block 661 and the groove, the wire reel 6 is fixed in the reel cover 11, preventing it from falling out. When the wire reel 6 needs to be removed, an outward tensile force is applied to the wire reel 6, and the elastic locking rod 66 is elastically deformed, allowing the wire reel 6 to be removed.

[0030] A further improvement is that an illumination device (not shown) is also arranged on the reel support shaft 12. When the rotation of the wire reel 6 stops, the identification device 7 scans and reads the information on the QR code. Since it is dark inside the housing 1, the illumination device provides a light source during the scanning process of the identification device 7, making it easier to scan and read the QR code. As an optional implementation, the illumination device can be a light-emitting diode (LED).

[0031] As an improvement, a through hole 67 leading to the shaft hole 642 is formed on the shaft cylinder 61, and the opening of the through hole 67 is larger than the diameter of the iron wire. When the iron wire is wound onto the receiving cavity 63, the head end of the iron wire passes through the through hole 67 and is knotted in the inner cavity of the shaft hole 642. The opening of the iron wire after the knotting process is larger than that of the through hole 67. Therefore, when the iron wire is used up or insufficient for the next binding, the knotted part of the binding wire can be blocked and cut off at the through hole 67, so that the head end of the iron wire can be effectively prevented from falling off the shaft cylinder 61 and entering the housing 1, which would affect the operation of the binding machine.In addition, the knotted part of the head end of the iron wire will not affect the normal rotation and use of the wire winding reel 6.

[0032] Preferably, a Bluetooth device (not shown) or a wireless communication device (not shown), a combination thereof, or another communication method is also provided in the housing 1, as long as data transmission can be realized. A memory (not shown) is also provided in the housing 1. The communication device and the memory can adopt existing communication methods and will not be repeated here. When the rotation of the wire reel 6 stops during use, the identification device 7 scans and reads the information on the QR code, and the processor decrypts the encrypted information. When there is no communication connection, the memory stores the data; and when there is communication connection, the information of the wire reel 6 is uploaded to a mobile phone or PC via a communication module, such as a WIFI module.

[0033] In a preferred embodiment, the roller flap 11 comprises a roller groove 111 arranged on the housing 1 and a cover plate arranged above the roller groove 111, the cover plate being movably connected to the roller groove 111. In particular, a locking device of the housing 1 is arranged on the housing 1, and one end of the cover plate is hinged to the housing 1, while the other end of the cover plate is provided with the locking device of the housing 1. The above-mentioned locking device of the housing 1 can be an existing detent element, a snap lock, or the like. In use, the locking device of the housing 1 is opened, and the cover plate is rotated to open, so that the groove 111 is opened. When the wire reel 6 is inserted into the groove 111, the cover plate is rotated to close, and the cover plate is locked to the housing 1 by the locking device of the housing 1.The above mechanism is simple and easy to use.

[0034] The above embodiments of the present invention are merely examples to clearly describe the present invention and are not intended to limit the implementations of the present invention. Those skilled in the art may make other variations or modifications in various forms based on the above description. It is unnecessary and impossible to implement all embodiments here. Any changes, equivalent substitutions, and improvements made without departing from the spirit and principle of the present invention are included within the scope of the appended claims of the present invention.
