Description

Technical Field

[0001] This invention relates to the field of article binding, and in particular to an automatic binding device. Background Technology

[0002] In practical engineering applications, existing cable trays must be installed and used in conjunction with dedicated cable tray covers. These covers typically require cable ties or other securing devices to ensure structural stability and system safety during operation. Currently, traditional cable tray cover binding operations usually require two operators, one on each side of the cable tray, to manually bind the covers simultaneously. This method is not only inefficient and fails to guarantee the strength and consistency of the bindings, but also significantly increases labor costs and the workload of the operators. Summary of the Invention

[0003] Therefore, the technical problem to be solved by the present invention is: how a single person can conveniently perform the binding operation of cable tray cover plates.

[0004] The above-mentioned technical problems are solved by the following technical solution: The present invention proposes an automatic binding device, which includes a snap-fit ​​body and a cable tie compartment disposed on the side wall of the snap-fit ​​body. The snap-fit ​​body is provided with a slide rail, which is connected to the inner wall of the cable tie compartment. The snap-fit ​​body is used to cover the outer wall of the object to be bound. The inner wall of the slide rail is provided with a pushing member, which can push the cable tie along the slide rail under the power of a first motor. When the cable tie moves along the slide rail more than one turn, the cable tie is taken out. At this time, the cable tie is located on the outer wall of the object to be bound.

[0005] In a preferred embodiment of the automatic binding device of the present invention: the end of the snap-fit ​​body is provided with an opening for inserting a snap fastener; the end face of the slide corresponding to the opening is provided with a limiting groove for placing the snap fastener.

[0006] In a preferred embodiment of the automatic binding device of the present invention: a rotating shaft is provided at the center of the cable tie compartment, and the rotating shaft is used to pass through the central axis of the disc-shaped cable tie; a U-shaped groove is provided at the connection between the cable tie compartment and the slide; after the center of the disc-shaped cable tie is inserted into the rotating shaft, one end of the cable tie is pulled through the U-shaped groove into the slide.

[0007] In a preferred embodiment of the automatic binding device of the present invention: one side wall of the snap-fit ​​body is an open inlet / outlet, and the cable tie can be inserted into the slide end face through the inlet / outlet.

[0008] In a preferred embodiment of the automatic binding device of the present invention: the snap-fit ​​body includes a first body and a second body connected to the first body via a rotating shaft; the rotating shaft can drive the second body to rotate, thereby controlling the opening state of the first body; when the first body is in the open state, it can snap into the outer wall of the object to be bound.

[0009] In a preferred embodiment of the automatic binding device of the present invention: a first magnetic block is provided at the end of the second body away from the rotation axis, and a second magnetic block is provided at the end of the first body away from the rotation axis; the first magnetic block and the second magnetic block cooperate to assist the first body and the second body in forming a closed state.

[0010] In a preferred embodiment of the automatic binding device of the present invention: the rotating shaft is disposed on the inner wall of the bottom end of the first main body, the rotating shaft is connected to the second motor, and the end of the rotating shaft away from the second motor is inserted into the inner wall of the bottom end of the second main body; when the rotating shaft rotates with the second motor, the part of the rotating shaft located at the bottom end of the first main body rotates freely with the inner wall of the first main body, and the part of the rotating shaft located at the bottom end of the second main body drives the second main body to rotate simultaneously.

[0011] In a preferred embodiment of the automatic binding device of the present invention: the slide is set in an inclined state, and the end of the slide near the inlet / outlet is higher than the end away from the inlet / outlet; the end face of the slide is provided with a weak magnetic surface layer, which prevents the cable tie from detaching from the slide when it moves along the surface of the slide under the pushing force of the pushing member; a baffle is provided at the inlet / outlet, and the baffle is made of a deformable material.

[0012] In a preferred embodiment of the automatic binding device of the present invention: the thrust member includes a connecting shaft connected to the first motor and a friction wheel disposed on the outer wall of the connecting shaft; the friction wheel is disposed above the end face of the slide, and when the cable tie is located between the friction wheel and the slide, the rotation of the friction wheel can drive the cable tie to move along the end face of the slide.

[0013] In a preferred embodiment of the automatic binding device of the present invention: a handle is provided below the snap-fit ​​body, and a first switch, a second switch and a third switch are provided on the end face of the handle; the first switch can control the power supply on / off state, the second switch is used to control the on / off state of the first motor, and the third switch is used to control the on / off state of the second motor.

[0014] The beneficial effects of the present invention are as follows: by setting an openable snap-fit ​​main body, the present invention solves the technical problem that it is difficult for a single person to conveniently bind items such as cable tray covers, and realizes that a single person can complete the binding operation. By setting up components such as a cable tie compartment, an inclined slide with a weak magnetic surface, a friction wheel pusher driven by a first motor, a limiting groove, and a buckle release opening, the technical problems of low efficiency, difficulty in ensuring firmness and consistency in traditional manual binding are solved, and the technical goals of stable cable tie conveying, convenient and efficient binding operation, and more uniform binding quality are achieved. By setting corresponding switches on the handle to control the power supply and the opening and closing of the two motors respectively, and in conjunction with the cutting structure, the operation process has been further optimized. This solves the technical problems of traditional binding operations requiring two operators, high labor costs, and high work intensity, significantly reducing construction labor costs and operator workload, while ensuring the structural stability and system safety of the bound items.

[0017] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] The terminology used in this invention is that which is currently widely used in the art in consideration of the function of the invention; however, these terms may vary according to the intent of those skilled in the art, precedent, or new technology in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the invention. Therefore, the terms used in this specification should not be construed as simple names, but rather based on their meanings and the overall description of the invention.

[0019] Reference Figures 1-3 This embodiment provides an automatic binding device, including a snap-fit ​​body 1 and a cable tie compartment 2 disposed on the side wall of the snap-fit ​​body 1. The snap-fit ​​body 1 is provided with a slide rail 3, which is connected to the inner wall of the cable tie compartment 2. The snap-fit ​​body 1 is used to cover the outer wall of the object to be bound. The inner wall of the slide rail 3 is provided with a pusher 4, which can push the cable tie to move along the slide rail 3 under the power of the first motor 8.

[0020] Reference Figure 3 The snap-fit ​​body 1 includes a first body 5 and a second body 6 connected to the first body 5 via a rotating shaft 721; An opening 11 is provided at the end of the first body 5, and the opening 11 is used to place the buckle.

[0021] In this embodiment, the buckle refers to the flat buckle used in the prior art for binding stainless steel cable ties. After the cable tie passes through the buckle, it can only be pulled in one direction to make the cable tie tighter, but it cannot be pulled in the opposite direction to make the cable tie looser.

[0022] When the clip is inserted into the slide rail 3 through the opening 11, it falls into the limiting groove on the end face of the slide rail 3, which is located directly below the opening 11. When the clip falls into the limiting groove, its end face is within the groove, while the clip's through-slot is not, allowing the cable tie to pass smoothly through the clip's through-slot. The clip's placement in the limiting groove prevents it from moving along the slide rail 3 simultaneously with the cable tie. In other words, the limiting groove acts as a stop for the clip.

[0023] Furthermore, refer to Figure 3 One end of the rotating shaft 721 extends into the bottom wall of the first main body 5 and is connected to the second motor 71 on the bottom wall of the first main body 5. The other end of the rotating shaft 721 extends into the bottom wall of the second main body 6 and is fixedly connected to the second main body 6. When the motor rotates, the end of the rotating shaft 721 located on the bottom wall of the first main body 5 rotates freely on the bottom wall of the first main body 5, so that the first main body 5 does not rotate. At the same time, the end of the rotating shaft 721 located on the bottom wall of the second main body 6 drives the second main body 6 to rotate synchronously, so that the second main body 6 rotates relative to the first main body 5.

[0024] It should be noted that the second motor 71 in this embodiment can be preset with a rotation angle. For example, after starting the motor switch, it can rotate 90° clockwise and then stop rotating; after starting the motor switch again, it can rotate 90° counterclockwise and then stop rotating. The above two actions constitute a set, and each set of actions can be completed by starting the motor switch twice. The above operation method of the second motor 71 is prior art, and this patent will not elaborate further.

[0025] Reference Figure 2 and Figure 3 When the two ends of the second main body 6 rotate to contact the two ends of the first main body 5 at the same time, the entire snap-fit ​​body 1 forms a closed state. When the rotating shaft 721 drives the end of the second main body 6 away from the rotating shaft 721 to rotate directly below the first main body 5, the first main body 5 is in an open state, and can be snapped into the outer wall of the object to be bound.

[0026] Furthermore, a first magnetic block 51 is provided at the end of the second body 6 away from the rotation axis 721, and a second magnetic block 61 is provided at the end of the first body 5 away from the rotation axis 721. When the second body 6 rotates to contact both ends of the first body 5, the second motor 71 stops rotating, and the first magnetic block 51 and the second magnetic block 61 attract each other, keeping the first body 5 and the second body 6 in a closed state. That is, the rotation axis 721 and the mutual attraction of the first magnetic block 51 and the second magnetic block 61 together keep the first body 5 and the second body 6 in a closed state. It should be noted that the attraction force of the first magnetic block 51 and the second magnetic block 61 is less than the rotational force of the second motor 71. Therefore, when the second motor 71 rotates counterclockwise, it can rotate the second body 6 to be directly below the first body 5, making the first body 5 in an open state.

[0027] Reference Figure 1 and Figure 2 Furthermore, the cable tie compartment 2 is fixedly disposed on the side wall of the first main body 5 away from the second main body 6. A compartment door may or may not be provided for the cable tie compartment 2, depending on usage requirements. A rotating shaft 21 is located at the center of the inner cavity of the cable tie compartment 2, which is used to pass through the central axis of the coiled cable tie. It should be noted that an elastic buckle is fixedly connected to the end of the rotating shaft 21 that does not contact the cable tie compartment 2. The elastic buckle is shaped like an almond kernel, allowing the center of the coiled cable tie to smoothly engage with the surface of the rotating shaft 21 from the end of the elastic buckle. After engaging with the surface of the rotating shaft 21, the elastic buckle acts as a limit for the coiled cable tie. When it is necessary to remove the coiled cable tie from the rotating shaft 21, the coiled cable tie needs to be pushed forcefully towards the elastic buckle until it disengages from the elastic buckle.

[0028] Furthermore, refer to Figure 1The side wall of the snap-fit ​​body 1 is an open-type entrance / exit 12. A U-shaped groove 22 is provided at the connection between the cable tie compartment 2 and the slide 3. The opening direction of the U-shaped groove 22 is the same as the opening direction of the side wall of the snap-fit ​​body 1.

[0029] After the center of the cable tie is inserted into the rotating shaft 21, pull one end of the cable tie by hand to rotate the shaft 21, and then pull out the end of the cable tie through the U-shaped groove 22 into the slide 3. That is, the open inlet / outlet 12 and the U-shaped groove 22 are designed to facilitate pulling the cable tie out of the cable tie compartment 2 and placing it into the end face of the slide 3 by hand.

[0030] Furthermore, refer to Figure 3 and Figure 5 The slide 3 is set at an angle, with the end of the slide 3 closer to the entrance / exit 12 being higher than the end farther from the entrance / exit 12; this setting can reduce the problem of cable ties coming off the slide 3 when sliding along the surface of the slide 3.

[0031] Furthermore, a weak magnetic surface layer 31 is provided on the end face of the slide rail 3, which ensures that the cable tie does not detach from the slide rail 3 when it moves along the surface of the slide rail 3 under the thrust of the thrusting member.

[0032] Furthermore, refer to Figure 5 A baffle 32 is installed at the entrance / exit 12 to prevent the cable ties from detaching from the slide rail 3. It should be noted that the height of the baffle 32 is less than the height of the slide rail 3, making it easier to put the cable ties into the slide rail 3 by hand. The baffle 32 is made of a deformable material to facilitate the removal of the cable ties from the slide rail 3 by hand.

[0033] Furthermore, refer to Figure 3 and Figure 4 The thrust component includes a connecting shaft 81 connected to the first motor 8 and a friction wheel 41 disposed on the outer wall of the connecting shaft 81; one end of the connecting shaft 81 is connected to the first motor 8, and the other end extends through one side wall of the first main body 5 into the slide rail 3 and is connected to the friction wheel in the slide rail 3.

[0034] It should be noted that, referring to Figure 4A first motor 8 is disposed on the inner wall of a housing 82. A magnetically generated block 83 is disposed at the bottom of the housing 82, and a metal sheet is connected to the outer wall of the bottom of the first motor 8. The magnetically generated block 83 and the metal sheet are connected by a supporting spring 84. The magnetically generated block 83 is connected to a first switch 13 via a wire. When the first switch 13 is open, the power is supplied, and the magnetically generated block 83 generates magnetic force that attracts the first motor 8 to move downwards. The downward movement of the first motor 8 drives the friction roller to move downwards. As the friction roller moves downwards, it can contact the cable tie, thereby increasing the friction between the friction roller and the cable tie, allowing the friction roller to rotate and move the cable tie along the surface of the slide rail 3. When the first switch 13 is closed, the power is not supplied, and the magnetically generated block 83 has no magnetic force. The first motor 8 moves upwards under the upward force of the supporting spring 84, returning to its initial height. At this time, the friction roller moves upwards and no longer contacts the cable tie. The upward movement of the friction roller facilitates the insertion and removal of the cable tie.

[0035] It should also be noted that the first motor 8 in this embodiment can be preset with a number of rotations. For example, when the first motor 8 is started, the shaft 21 of the first motor 8 rotates 180 times and then automatically stops rotating. When the first motor 8 is started again, the shaft 21 of the first motor 8 rotates 180 times and then automatically stops rotating. When the shaft of the first motor 8 rotates 180 times, the cable tie rotates 1.1 times along the slide 3 through friction and rolling, so that two layers of the cable tie pass through the buckle at the same time. The above operation method of the first motor 8 is prior art, and this patent will not elaborate further.

[0036] Furthermore, refer to Figure 6 A cutter 16 is also provided at the end of the first main body 5. The cutter 16 is connected to the two side walls of the cutter opening at the end of the first main body 5 via a torsion spring shaft 18. A return spring 19 is provided below the two side walls of the cutter opening on the torsion spring shaft 18, so that when the cutter 16 is subjected to downward pressing force, it can drive the torsion spring shaft 18 to move downward at the same time. When the pressing force is removed, the cutter 16 and the torsion spring shaft 18 return to their initial height under the upward force of the return spring 19. The cutter 16 is located on the side wall of the friction roller near the cable tie compartment 2. The initial state of the cutter 16 is inclined, at which time the cutter 16 does not contact the end face of the slide 3, which facilitates the placement of the cable tie on the end face of the slide 3. When it is necessary to cut the cable tie, rotate the cutter 16 to a state perpendicular to the end face of the slide 3, and then press the cutter 16 downward with force. This causes the cutter 16 to penetrate the cable tie, thereby separating the cable tie into two segments. Then release, and the cutter 16 and the torsion spring shaft 18 return to their initial height under the upward force of the return spring 19.

[0037] In some embodiments, a handle 9 is provided below the snap-fit ​​body 1, and a receiving cavity is provided on the inner wall of the handle 9, which contains a battery, i.e., the power source of the entire device. A first switch 13, a second switch 14, and a third switch 15 are provided on the end face of the handle 9; the first switch 13 can control the power supply on / off state, the second switch 14 is used to control the first motor 8 on / off state, and the third switch 15 is used to control the second motor 71 on / off state.

[0038] Working process: In the initial state, the second main body 6 rotates until it is perpendicular to the first main body 5, making the first main body 5 open. The friction roller is directly above the slide rail 3 without contacting the slide rail 3; this is the initial height of the first motor 8.

[0039] In use, first, insert the center of the cable tie into the surface of the rotating shaft 21 along the elastic buckle at the end of the rotating shaft 21. Then, insert the first body 5 into the surface of the bundled item. Then, pull out one end of the cable tie by hand, and move the cable tie along the cable tie compartment 2 through the opening of the U-shaped groove 22 into the slide rail 3 and move it directly below the friction roller. At this time, press the first switch 13 to start the power. When the power is started, it drives the friction roller to move downward and contact the surface of the cable tie. Then, press the third switch 15 to make the second motor 71 rotate 180 degrees clockwise. At this time, the rotating shaft 721 drives the second body 6 to rotate 180 degrees counterclockwise until it contacts both ends of the first body 5 at the same time. At this time, the locking body 1 is in the closed state. Then, press the second switch 14 to start the first motor 8. When the first motor 8 rotates, it drives the friction roller to rotate at the same time. When the friction roller rotates, it drives the cable tie to move along the surface of the slide rail 3. The first motor 8 automatically stops rotating when the cable tie has moved 1.1 turns along the surface of the slide rail 3, meaning that two layers of the cable tie have passed through the buckle simultaneously. At this point, the cutter 16 is rotated until it is perpendicular to the end face of the slide rail 3, and then the cutter 16 is pressed down forcefully. This causes the cutter 16 to penetrate the cable tie, thus separating the cable tie into two pieces. Then, the pressure is released, and the cutter 16 and the torsion spring shaft 18 return to their initial height under the upward force of the return spring 19.

[0040] Then, manually remove the cable tie back slide 3 to the surface of the object to be tied, and then press the third switch 15 to make the second motor 71 rotate 180 degrees counterclockwise, so that the second body 6 rotates to the position directly below the first body 5. At this time, the first body 5 is in an open state. Then press the first switch 13 to turn off the power.

[0041] Next, move the first main body 5 until it no longer covers the surface of the object to be tied, and finally tighten the cable ties by hand to complete the tying work.

[0042] In summary, this invention allows one person to complete the binding of wide items, and the binding process is convenient and efficient. It solves the technical problem in existing technologies where binding cable tray covers requires two workers to stand on both sides of the cover for manual binding, resulting in slow work efficiency and high labor costs.

[0043] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of the present invention.
