Description

Technical Field

[0001] This utility model relates to the field of wire feeding equipment technology, specifically to an electronic lock-locking wire feeding mechanism. Background Technology

[0002] When using a binding gun for binding operations, the wire feeding mechanism needs to continuously supply binding wire to the binding gun to ensure the continuity of the operation. Since the binding wire is dragged by the binding gun during the binding process, it can assist in the passive and uniform release of the wire from the spool. Therefore, in some applications, to simplify the structure and reduce costs, only a freely rotating spool is used as the wire feeding device. However, this simplified solution has significant drawbacks in practical applications: when the amount of binding wire on the spool decreases, leading to a reduction in overall inertia, or when the friction between the spool and the support shaft is insufficient (the spool rotates too smoothly), the dragging of the binding wire by the binding gun after completion can easily cause the spool to rotate excessively. At this time, the binding wire continues to be released under inertia, forming a redundant drooping section. Coupled with the lack of a drive source to actively control the wire release rhythm, it is very easy for tangling and knotting to occur due to the swinging and stacking of the slack section. This can lead to interruptions in the binding process or, in severe cases, wire breakage or equipment jamming.

[0003] The improved wire feeding schemes described above typically employ a coordinated design of a rotary wire roll and a drive source (such as a geared motor): the wire roll is wound with binding wire, one end of which extends to the working end of the binding gun. When the binding gun consumes the binding wire, the drive source releases the binding wire synchronously by precisely controlling the rotation speed of the wire roll. However, the selection of drive sources such as geared motors not only increases equipment costs but also requires corresponding voltage and other power resources to operate, resulting in higher operating and maintenance costs.

[0004] To address these issues, we propose an electronic lock-locking wire feeding mechanism. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing an electronic lock-locking wire feeding mechanism. Based on the design of passive wire roll, this wire feeding mechanism uses a low-cost and simple locking component to act linearly on the outer edge of the passive wire roll, thereby achieving convenient locking of the position of the passive wire roll.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] An electronic lock-locking wire feeding mechanism includes a passive wire roll for supplying and rotating binding wire to a binding gun, and a locking member for locking the position of the passive wire roll. A follower disk is coaxially arranged on the passive wire roll, and multiple teeth are arranged in a circumferential array on the outer edge of the follower disk. An interlocking area is formed between any two adjacent teeth. The locking member has a pin that can move linearly. The movement path of the pin intersects with the movement path of the interlocking area, so that the pin that moves linearly can be inserted into the interlocking area.

[0008] As a further embodiment of this utility model: the passive wire roll includes a spool for winding the binding wire and end discs coaxially disposed at both ends of the spool, wherein the outer edge of any of the end discs is provided with a plurality of teeth arranged in a circumferential array to form the follower disc.

[0009] As a further embodiment of this utility model, the wire feeding mechanism also includes a shaft for rotating the reel, and the shaft is provided with a clamping member for axially limiting the reel.

[0010] As a further embodiment of this utility model: the clamping member includes a top ring and a retaining sleeve both sleeved on the shaft body, and the top ring is located between the retaining sleeve and the scroll and can abut against one end of the scroll body, and the retaining sleeve abuts against the top ring and can be fixedly installed on the shaft body to lock the position of the top ring.

[0011] As a further embodiment of this utility model: a hollow tube is coaxially arranged in the middle of the scroll and sleeved on the shaft body, and multiple protrusions are arranged in a circumferential array on the inner side of the hollow tube. The virtual circle formed by the near ends of the multiple protrusions is adapted to the diameter of the cross-sectional circle of the shaft body. The end of the top ring near the hollow tube is designed to be constricted and forms a constricted end, and the constricted end is adapted to the diameter of the hollow tube to achieve the contact and limiting of the end of the hollow tube against the constricted end.

[0012] As a further embodiment of this invention: a ball bearing is movably provided at the end of the pin, so that the sliding contact between the end of the pin and the teeth is transformed into rolling contact.

[0013] As a further embodiment of this utility model: the locking component is an electronic lock with a telescopic rod, and the telescopic rod constitutes the pin.

[0014] As a further embodiment of this utility model, the wire feeding mechanism also includes a carrier plate for fixing and installing the shaft and locking components.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This application designs a passive wire roll that relies solely on the traction force of the binding wire to achieve rotary feeding, simplifying the power system structure and reducing energy consumption. Unlike the coaxial locking method used in existing technologies for passive wire rolls, this application's outer contour locking method requires only a simple device to apply a small braking force to achieve braking. Simultaneously, the circumferential teeth of the follower disc cooperate with the linear telescopic pin of the locking component. When the pin is inserted linearly into the intersecting area between the teeth, the wire roll position is instantly locked, effectively preventing the binding wire from springing back or loosening, ensuring continuous wire feeding. Compared to the high-cost drive source used in existing technologies, the locking component in this application not only achieves convenient locking of the passive wire roll but is also inexpensive and simple in structure. Furthermore, during use, some locking components can be operated with low pressure, reducing operating costs.

[0017] 2. By integrating the follower plate with the end plate, the teeth are directly machined on the outer edge of the end plate, eliminating the need for separate follower plate installation, reducing the number of parts and assembly complexity, and lowering manufacturing costs.

[0018] 3. The combined design of the shaft and the clamping component enhances the stability of installation and operation. The clamping component restricts the axial displacement of the reel, preventing wire roll deviation caused by tension fluctuations and ensuring the straightness and consistency of the wire feeding path. Simultaneously, the shaft, as an independent support structure, supports quick disassembly and maintenance of the reel, adapting to the flexible replacement needs of different wire roll specifications. Furthermore, by adjusting the limiting force of the clamping component, it can be compatible with lightweight packaging materials or heavy-duty industrial binding wire, expanding the application scenarios of the mechanism.

[0019] 4. The coordinated design of the hollow tube and the constricted end optimizes coaxial accuracy and limiting effect. The protrusion on the inner side of the hollow tube matches the cross-sectional circle of the shaft, forcibly constraining the strict coaxiality of the roll and the shaft, eliminating the risk of eccentric rotation. At the same time, the contact limiting between the constricted end and the end of the hollow tube forms a double axial constraint, preventing the top ring from loosening due to long-term vibration and ensuring limiting stability.

[0020] 5. The introduction of ball bearings significantly improves friction performance. The ball bearings convert the sliding friction between the pin and the teeth into rolling friction, reducing wear on the contact surface and extending the service life of the locking components. At the same time, the rolling friction resistance is extremely low, ensuring that the pin is in a locked, engaged state within the insertion area as much as possible, avoiding the formation of an unstable sliding contact state between the pin and the teeth.

[0021] 6. Intelligent control is achieved by using an electronic lock to drive the telescopic rod as a pivot. The electronic lock can precisely control the stroke and timing of the telescopic rod through electrical signals, which is suitable for the high-precision synchronization requirements of automated production lines.

[0029] 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.

[0030] like Figures 1-4 As shown, an electronic lock-type wire feeding mechanism includes a carrier plate 10 mounted on the same frame as the binding gun a. A passive wire roll (a wire roll without an external drive source) 1 is rotatably mounted on the carrier plate 10, and a locking element 2 is also provided on the carrier plate 10 for locking the position of the passive wire roll 1. In use, one end of the binding wire on the passive wire roll 1 is placed at the working end of the binding gun a. The binding gun a performs binding work, pulling the binding wire to achieve self-rotation feeding of the passive wire roll 1. At the moment the continuous work of the binding gun a ends, the locking element 2 can immediately lock the position of the passive wire roll 1, preventing excessive rotation of the passive wire roll 1 and redundant sagging of the binding wire due to the dragging force applied by the binding gun a. The locking element 2 has a pin 201 capable of linear extension and retraction. When it is necessary for the passive wire roll 1 to stop rotating, the pin 201 of the locking element 2 extends linearly towards the passive wire roll 1 to brake it, thus stopping the rotation of the passive wire roll 1. Preferably, the lock element 2 can be configured as a low-cost and simple electronic lock or the like in the prior art.

[0031] Compared to existing technologies that control the rotation of the wire roll using a geared motor, this application eliminates the need for a drive source, rendering the wire roll passive (1). It simply adds a low-cost, simple-structure locking device (electronic lock) 2 to lock the position of the passive wire roll 1 after the bundling process. The locking method is simple and quick, and some locking devices 2 only require low voltage (e.g., 24V), reducing operating costs. Unlike existing coaxial locking methods for the passive wire roll 1, this application's outer contour locking method for the passive wire roll 1 requires only a simple device to apply a small braking force to achieve braking.

[0032] like Figures 2-4 As shown, in order to achieve convenient locking of the passive wire coil 1 by the locking element 2, this application provides the following structural design for the passive wire coil 1:

[0033] The passive wire spool 1 includes a spool 101 and end plates 102 disposed at both ends of the spool 101. The spool 101 is used for winding the binding wire, and the end plates 102 are used to limit the axial displacement of the binding wire to ensure neat winding. A follower plate 3 is coaxially disposed on the spool 101. To save materials, either of the end plates 102 can be designed as a follower plate 3. The outer edge of the follower plate 3 is circumferentially arrayed with multiple teeth 301. An interlocking area is formed between any two adjacent teeth 301. When the passive wire spool 1 rotates, the multiple interlocking areas rotate around the spool 101. The movement path of the pin 201 on the electronic lock intersects with the movement paths of the multiple interlocking areas. The layout relationship between the pin 201 and the follower plate 3 can be determined by... Figure 2 This is represented by the following: During normal operation, the pin 201 of the electronic lock retracts to move away from the insertion area, allowing the passive wire roll 1 to rotate under the dragging force of the binding gun a, achieving uniform feeding. When the binding gun a finishes its binding operation, the pin 201 on the electronic lock extends into the movement path of the insertion area until it is fully inserted into the insertion area, thus locking the position of the passive wire roll 1. This state can be represented by... Figure 2 To represent it.

[0034] like Figures 1-2 As shown, in order to realize the rotational installation of the passive wire roll 1 on the carrier plate 10, based on the setting of the spool 101, this application fixes a horizontally arranged shaft 4 on the carrier plate 10. The spool 101 is movably sleeved on the shaft 4, and the shaft 4 is provided with a clamping member for axially limiting the spool 101. When the spool 101 is sleeved on the shaft 4, the axial position of the spool 101 can be limited and fixed by the clamping member, so that the spool 101 can only rotate.

[0035] For example Figures 2-4As shown, the aforementioned clamping component can be any conventional technique in the prior art, such as a clamp that can be locked onto the shaft 4. This article provides a clamping component with the following structure: the clamping component includes a top ring 5 and a retaining sleeve 6, both sleeved on the shaft 4. The top ring 5 is located between the retaining sleeve 6 and the scroll 101 and can abut against one end of the scroll 101. The axial position of the retaining sleeve 6 on the shaft 4 is adjustable and can abut against the top ring 5. Simultaneously, the position of the retaining sleeve 6 on the shaft 4 can be fixed to lock the position of the top ring 5. Since both ends of the top ring 5 abut against the scroll 101 and the retaining sleeve 6 respectively, locking the position of the top ring 5 will lock the position of the scroll 101. Locking the position of the retaining sleeve 6 on the shaft 4 is a conventional technique in the prior art, and will not be elaborated upon here to avoid unnecessary detail.

[0036] Furthermore, a hollow tube 7 is coaxially mounted on the shaft body 4 at the center of the scroll 101. The inner diameter of the hollow tube 7 is smaller than the diameter of the scroll 101, and larger than the diameter of the shaft body 4. Based on this design, multiple protrusions 8 are arranged in a circumferential array on the inner side of the hollow tube 7. The virtual circle formed by the protrusions 8 at their proximal ends is adapted to the diameter of the cross-sectional circle of the shaft body 4. Correspondingly, the top ring 5 is designed with a constricted end near the hollow tube 7, and this constricted end is adapted to the diameter of the hollow tube 7 to achieve complete contact and limitation of the end of the hollow tube 7 against the constricted end.

[0037] During the insertion of the interlocking areas on the follower disk 3 using the pin 201 of the electronic lock, even if the number of interlocking areas on the follower disk 3 is sufficient and the arrangement is close, there will still be instances where the pin 201 abuts against the teeth 301 during its extension action. Although this contact between the pin 201 and the teeth 301 can still brake and lock the passive wire roll 1 through the sliding friction between them, the contact between the pin 201 and the teeth 301 is a sliding contact, and this contact-locked state is unstable. The passive wire roll 1 is prone to rotation when affected by external forces. Therefore, to avoid this contact-locking situation, such as... Figure 5 As shown, a ball bearing 9 is movably provided at the end of the pin 201 in this application. Therefore, when the pin 201 extends, even if the end of the pin 201 abuts against the tooth 301, the presence of the ball bearing 9 can change the original sliding contact between the end of the pin 201 and the tooth 301 into a rolling contact. Under this rolling contact, the braking effect on the passive wire roll 1 is small, so the passive wire roll 1 can still rotate under inertia. When the insertion area on the passive wire roll 1 closest to the pin 201 moves to the movement path of the pin 201, the pin 201 will be inserted into the insertion area to achieve the snap-locking of the passive wire roll 1. This snap-locking method is relatively stable.

[0038] Of course, the setting for accurately inserting the pin 201 into the insertion area is not limited to the ball bearing 9 design mentioned above. It can also be achieved by adding a sensing component from the prior art. For example, a proximity switch can be added. The proximity switch is used to monitor whether there is a tooth 301 passing through the movement path of the pin 201. If no tooth 301 passes through, a corresponding signal is sent to control the pin 201 to extend, so that the pin 201 can be accurately inserted into the insertion area.

[0039] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
