Description

Technical Field

[0001] The invention relates to the technical field of spring coil opening machines, in particular to an anti-winding device for thin-wire springs. Background Art

[0002] In the production and processing of mechanical parts, fine-wire springs, as a fundamental and critical component, are widely used in numerous industries, including electronics, precision instruments, and medical devices. However, due to their small diameter, high elasticity, and light weight, fine-wire springs are prone to intertwining and entanglement during continuous production and collection by spring coiling machines, forming difficult-to-handle clumps. This has been a common technical challenge plaguing production in this field.

[0003] To address this issue, the industry's common practice is to rely on manual labor. After spring production is complete, workers must rely on experience and feel, sometimes supplemented by simple tools like tweezers and hooks, to sort the tangled springs one by one. This approach has significant drawbacks. Not only is sorting inefficient and labor-intensive, but the pulling and separating process can easily cause irreversible plastic deformation or damage to the springs, leading to high product scrap rates and compromising final product quality and economic returns.

[0004] To improve efficiency, attempts were made to introduce traditional automated material separation devices, such as vibrating plates. However, practice has proven that these devices are poorly suited for thin-wire springs. On the one hand, the high-frequency vibrations of the vibrating plates can easily damage the fragile, thin-wire springs. On the other hand, the chaotic tumbling caused by the vibrations can exacerbate spring entanglement and entanglement, preventing effective separation and orderly arrangement. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a device to prevent fine-wire springs from winding, which solves the problems in the existing technology that fine-wire spring workpieces are easily entangled after production and that manual sorting is inefficient and easily damages the products.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A fine-wire spring anti-winding device includes a frame, a spring coil opener is installed on the top of the frame, one end of the spring coil opener is driven by a power mechanism installed on one side of the interior of the frame, the power mechanism includes a motor and a reducer installed at its output end, the reducer is used to supply energy to a cooling component, the cooling component is installed on the inner wall of the frame, a conveyor belt is installed on one side of the interior of the frame, and an independent component is installed on the top of the frame, which is connected to the discharge end of the spring coil opener and is used to receive and process the workpiece; The independent component includes a material receiving plate, which is fixedly connected to the top of the frame, a storage box is installed at the bottom of the material receiving plate, a plurality of scrolls are rotatably connected inside the storage box, a connecting block is fixedly connected to the inner wall of the storage box, a plurality of locking rods are fixedly connected to the bottom of the connecting block, one end of the locking rod is fixedly connected to a motor for driving the heat sealing disk rotatably connected to one side of the locking rod to rotate, and a pulley group is installed at one end of the heat sealing disk.

[0007] The above technical solution, through the provision of a splicing plate, can guide each workpiece produced by the spring coiling machine into the storage box, preventing the workpieces from scattering and accumulating. Secondly, as the heat-sealing disk rotates, it continuously pulls the film from the reel and simultaneously completes the longitudinal heat-pressure sealing of both sides of the film, forming a continuous tubular package that wraps the spring. This design can quickly physically isolate the spring as soon as it leaves the production machine and before it has the opportunity to come into contact with other springs, fundamentally eliminating the occurrence of entanglement, improving production efficiency and product qualification rate, and reducing human intervention.

[0008] Preferably, the pulley group includes multiple pulleys, one of which is connected to a turntable rotatably connected to one end of a locking rod, one end of the turntable is rotatably connected to a connecting rod, one end of the connecting rod is rotatably connected to a docking rod, the docking rod is fixedly connected to one end of multiple edge banding knives, and the inner wall of the locking rod is fixedly connected to multiple limit blocks.

[0009] Through this technical solution, the pulley assembly transmits rotational power from upstream to the turntable. A crank-connecting rod mechanism, comprised of the turntable, connecting rod, and docking rod, converts the continuous rotational motion into a periodic, reciprocating opening and closing movement of the edge-banding blade. Because the power driving the edge-banding blade derives from the same source as the power driving the longitudinal movement of the film and is transmitted through a mechanical hard-wired connection, the frequency of the transverse sealing and cutting motions is precisely matched to the longitudinal film feed speed. This not only eliminates the need for complex electronic synchronization logic, reducing equipment costs and failure rates, but also ensures that each sealing and cutting occurs at the exact location, guaranteeing the independence, integrity, and sealing of each spring packaging unit.

[0010] Preferably, a plurality of sliding rods are fixedly connected to the inner wall of the limit block, the edge banding knife is slidably connected to the outer wall of the sliding rod, and a spring is installed on one side of the outer wall of the sliding rod.

[0011] Preferably, the two edge banding knives are embedded in each other at one end, one end of one of the edge banding knives is fixedly connected to a plurality of heating tubes, one end of one of the edge banding knives is provided with a receiving groove, and the heating tubes are slidably connected to the inner wall of the receiving groove.

[0012] Preferably, the two heat-sealing discs are in contact with each other and rotate relative to each other to perform plastic sealing on both sides of the film.

[0013] Preferably, the cooling component includes a bellows, which is fixedly connected to the inside of the frame, an air intake grille is installed at one end of the bellows, and a plurality of through holes are opened on the outside of the bellows, the inner wall of the bellows is rotatably connected to a transmission rod, one end of the transmission rod is connected to the output end of the reducer, and is used to drive the fan blades on the outer wall of the transmission rod to rotate, and an air nozzle is installed at one end of the bellows.

[0014] Preferably, a windshield is fixedly connected to one end of the top of the frame, a ventilation slot is provided in the middle of the windshield, a collection box is fixedly connected to one end of the windshield, and the collection box is communicated with the ventilation slot.

[0015] Preferably, the air nozzle is horizontally aligned with the ventilation slot and is used to blow and cool the packaging workpieces on the conveyor belt.

[0016] Preferably, a guide tube is fixedly connected to the bottom of the storage box, and the guide tube is perpendicular to one side of the conveyor belt.

[0017] Preferably, the plurality of limit blocks are arranged symmetrically, and the edge banding knife is slidably connected to the inner wall of the limit block.

[0018] Working principle: When the user uses this device to make fine-diameter springs, the power mechanism is first started to drive the spring coil opener. During the continuous operation of the spring coil opener, in order to prevent the workpieces from entangled with each other or damaged due to entanglement, the spring coil opener can be directly connected to the discharge end of the spring coil opener through an independent component.

[0019] When the workpiece is processed by the spring coil opening machine and comes out from the discharge end, it will first fall on the top of the receiving plate. Since the receiving plate is at an inclined angle, the workpiece will fall along the receiving plate into the storage box and be caught by the connecting groove. At this time, the motor can be turned on to drive the heat sealing disk to rotate, and then the plastic film on the outer wall of the reel is pulled to move by the adhesion of the two heat sealing disks. During the pulling process, the plastic films on both sides are adhered by heating. As the friction contact between the plastic film and the workpiece increases, the falling speed of the workpiece can be reduced.

[0020] To reduce the possibility of entanglement caused by contact between workpieces, as the plastic film and workpieces continue to move downward in the storage box, the heat-sealing disc transmits power through the pulley assembly, driving the turntable on one side of the locking rod to rotate. This, in turn, drives the edge-banding knife sliding inside the limit block to move synchronously in close and distant directions via a connecting rod connected to the eccentric center. The contact area of ​​the edge-banding knife on both sides is specially designed, with a heating tube and a receiving groove installed at one end. When the two edge-banding knives are in contact, the plastic film can be cut, and the heating of the heating tube achieves the upper and lower plastic sealing of the plastic film at both ends. This design allows each workpiece to be in an independent space, and the coordination of the spring and the slide rod can improve the stability of the edge-banding knife movement.

[0021] Subsequently, each independent workpiece will be guided to the top of the conveyor belt through the guide tube. In order to avoid the high plastic sealing temperature and the adhesion with the conveyor belt surface, the cooling component will be driven synchronously during the power output of the power mechanism. The cooling component will drive the external fan blades to rotate during the rotation, and then inhale air through the direction of the air intake grid, and cool the plastic film workpiece passing through the outside of the conveyor belt through the air nozzle horizontally. There is also an additional function. Due to the time difference in the movement of the workpiece between the spring coil opening machine and the independent component, plastic sealing air and additional plastic debris generated during the plastic sealing process will appear. If they are handled, additional manual input is still required. Due to the design of this mechanism, during the cooling process, the lighter non-workpieces can be blown into the collection box through the ventilation slots to achieve automatic separation, which can ensure anti-sticking while improving the anti-winding effect, thereby improving processing quality and reducing labor costs.

[0022] The present invention provides a device for preventing the winding of thin-wire springs. It has the following beneficial effects: 1. The present invention uses a locking rod, a reel, a connecting block, a turntable and other parts in conjunction with each other, and can directly perform anti-winding protection treatment on a single workpiece after the wire diameter spring workpiece is produced, thereby avoiding deformation and damage caused by winding of the workpiece, saving the manual sorting process after the traditional processing process, and effectively saving labor costs.

[0023] 2. The present invention can achieve the effects of automatic plastic sealing and bottom sealing during use through the coordinated use of parts such as a pulley group, a hot air disk, and a motor, and improve the processing efficiency through transportation by a conveyor belt. It also has a cooling component to avoid sticking and other adverse effects in the process of achieving the above functions.

[0024] 3. The present invention uses ventilation slots, windshields, collection boxes and other parts in combination to reduce the occurrence of debris and empty packages caused by thermoplastic molding during use, thereby avoiding manual assistance and improving processing quality.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Please see the attached Figure 1 -Attached Figure 3An embodiment of the present invention provides an anti-winding device for fine-wire springs, comprising a frame 1, a spring coil opener 2 mounted on the top of the frame 1, one end of which is driven by a power mechanism 3 mounted on one side of the interior of the frame 1, the power mechanism 3 comprising a motor and a reducer mounted on its output end, the reducer being used to supply energy to a cooling component 6, the cooling component 6 being mounted on the inner wall of the frame 1, a conveyor belt 5 being mounted on one side of the interior of the frame 1, an independent component 4 being mounted on the top of the frame 1, which is connected to the discharge end of the spring coil opener 2 for receiving and processing workpieces.

[0029] Specifically, the motor within the power mechanism 3 converts high-speed electrical energy into stable mechanical energy with increased torque through a speed reducer, directly driving the spring coil slitter 2 to perform the spring winding operation. The spring coil slitter 2 and the independent component 4 are directly connected at the feed and discharge ports, allowing each newly formed spring to be captured and isolated by the independent component 4 the moment it loses its restraints, thereby preventing the spring workpieces from becoming entangled due to accumulation or collision.

[0030] During operation, the reducer in the power mechanism 3 will divert a portion of the power to drive the cooling component 6, and through the cooling component 6 and the conveyor belt 5, the cooling airflow generated by the cooling component 6 can act on the workpiece that has fallen or is about to fall on the conveyor belt 5, quickly solidifying its surface and eliminating stickiness, and ensuring that the workpiece can slide and be transported smoothly on the conveyor belt 5 without adhesion, thereby ensuring the stability of the entire automated process.

[0031] Please see the attached Figure 4 -Attached Figure 8The independent component 4 includes a material receiving plate 401, which is fixedly connected to the top of the frame 1. A storage box 402 is installed at the bottom of the material receiving plate 401. A plurality of scrolls 403 are rotatably connected to the interior of the storage box 402. A connecting block 404 is fixedly connected to the inner wall of the storage box 402. A plurality of locking rods 405 are fixedly connected to the bottom of the connecting block 404. One end of the locking rod 405 is fixedly connected to a motor 409 for driving a heat sealing disk 408 rotatably connected to one side of the locking rod 405. A pulley set 407 is installed at one end of the heat sealing disk 408. The pulley assembly 407 includes multiple pulleys, one of which is connected to a rotating disk 416 rotatably connected to one end of the locking rod 405. A connecting rod 417 is rotatably connected to one end of the rotating disk 416. A docking rod 418 is rotatably connected to one end of the connecting rod 417. The docking rod 418 is fixedly connected to one end of multiple edge banding blades 413. The inner wall of the locking rod 405 is fixedly connected to multiple limit blocks 410. The inner wall of the limit blocks 410 is fixedly connected to multiple sliding rods 411. The edge banding blades 413 are slidably connected to the outer walls of the sliding rods 411. A spring 412 is mounted on one side of the outer wall of the sliding rods 411. Two edge banding blades 413 are interlocked at one end. One of the edge banding blades 413 is fixedly connected to one end of the multiple heating tubes 415. One of the edge banding blades 413 has a receiving slot 414 defined at one end. The heating tubes 415 are slidably connected to the inner wall of the receiving slot 414. Two heat-sealing discs 408 fit together and rotate relative to each other, sealing both sides of the film. A guide tube 406 is fixedly connected to the bottom of the storage box 402, perpendicular to one side of the conveyor belt 5. Multiple stoppers 410 are symmetrically arranged, and edge-sealing blades 413 are slidably connected to the inner walls of the stoppers 410.

[0032] Specifically, the traditional method of producing fine-wire springs is usually to collect the workpieces processed by the spring coil opener 2 directly into a material box. However, since the fine springs themselves are easily deformed and intertwined, a large number of workpieces will be entangled together, forming clumps that are difficult to separate. Subsequently, manual labor must be used to carefully sort them. This process is not only inefficient, but also easily causes tensile deformation or damage to the springs during the sorting process, which directly leads to the problems of low product qualification rate and high labor costs. The present application, by providing an independent component 4 directly connected to the discharge end of the spring coil opener 2, realizes that the workpiece is immediately independently packaged with a thin film before it comes into contact with other workpieces. Through this design, the possibility of entanglement is eliminated, all subsequent manual sorting processes are eliminated, and work efficiency is improved.

[0033] Specifically, the spring workpiece first slides into the storage box 402 via the material receiving plate 401. Then, the motor 409 fixed to the locking rod 405 is activated, driving the rotation of a pair of heat-sealing disks 408 facing each other. By utilizing the rotation of the heat-sealing disks 408, the film from multiple reels 403 is continuously and synchronously pulled downward, and the edges of the film are heated and pressed together during the pulling process, forming a continuous, upward-opening tubular package. This allows the newly dropped spring workpiece to be immediately received and wrapped by this tubular package, completing the initial longitudinal isolation.

[0034] To achieve independent sealing of each workpiece, the rotational power of the heat sealing disk 408 is transmitted to the turntable 416 through the pulley set 407 at one end. The turntable 416 acts as an active crank, and through the transmission of the connecting rod 417 and the docking rod 418, it converts its own rotational motion into a periodic reciprocating linear motion of the edge banding knife 413.

[0035] When the two edge-sealing blades 413 move toward each other and engage, the heating tube 415 on one side enters the receiving groove 414 on the other side. The heat from the heating tube 415 simultaneously heat-melts and seals the tubular film transversely. This design allows for a single closing action that simultaneously seals the bottom of the upper package containing the spring and the top of the lower package awaiting the spring. This repetitive cycle divides the continuous tubular package into fully enclosed, independent packaging units, each containing a single spring.

[0036] Finally, the guide tube 406 at the bottom of the storage box 402 falls to the designated position of the conveyor belt 5, completing the anti-winding function.

[0037] Please see the attached Figure 1 , Attachment Figure 9 The cooling assembly 6 includes a bellows 601, which is fixedly connected to the interior of the frame 1. An air inlet grille 602 is mounted on one end of the bellows 601, which has multiple through-holes. A transmission rod 603 is rotatably connected to the inner wall of the bellows 601. One end of the transmission rod 603 is connected to the output end of the reducer, driving the fan blades 604 on the outer wall of the transmission rod 603 to rotate. A nozzle 605 is mounted on one end of the bellows 601. A windshield 606 is fixedly connected to one end of the top of the frame 1. A ventilation slot 608 is defined in the middle of the windshield 606. A collection hopper 607 is fixedly connected to one end of the windshield 606, which communicates with the ventilation slot 608. The nozzle 605 is horizontally aligned with the ventilation slot 608 and is used to blow air to cool the packaged workpieces on the conveyor belt 5.

[0038] In the prior art, even if packaging can be achieved, the secondary problems caused by the hot plastic sealing process are often ignored. For example, the packaging bag with a high temperature after packaging will become sticky when it falls on the conveyor belt 5, causing material accumulation and blockage, and ultimately leading to the interruption of the entire automated production line. The superiority of this application lies in its systematic design considerations. Not only does it realize automated plastic sealing and cutting through components such as motor 409 and pulley assembly 407, but it also provides a cooling component 6 that is directly linked to the power mechanism 3, achieving the effect of cooling the workpiece packaging as long as production is in progress.

[0039] In addition, in the automated production process, empty packages generated due to equipment idling or material problems, as well as plastic debris generated during the cutting process, are common factors that affect the quality of the final product batch. Existing technologies usually require additional manual or visual screening processes to remove these waste products. The present invention utilizes the airflow generated by the cooling component 6 to achieve the function of automatic impurity removal. By precisely designing the angle and airflow intensity of the nozzle 605, and coordinating the installation of the windshield 606 and the collection box 607, it is possible to cool the workpiece while blowing out and collecting waste materials such as empty packages and debris that are significantly lighter in weight from the mainstream product, thereby further reducing manual intervention and improving product quality.

[0040] Specifically, the power from the reducer in the main transmission system is directly connected to the transmission rod 603 inside the cooling assembly 6. When the transmission rod 603 rotates, the fan blades 604 on its outer wall rotate at high speed inside the bellows 601, thus creating a negative pressure at one end of the air inlet grille 602, drawing in external air. This is then pressurized and ejected through the nozzle 605 at the other end, forming a stable and directional airflow. This utilizes the principle of forced convection heat transfer to quickly remove the residual heat generated by heat sealing on the workpiece packaging surface, causing the film surface to quickly solidify and lose its viscosity.

[0041] Secondly, the air nozzle 605 is horizontally aligned with the ventilation slot 608 in the middle of the windshield 606. When the airflow blows toward the conveyor belt 5, the movement of qualified workpieces, including metal springs, is not affected by the airflow due to their inherent mass. However, empty bags or plastic debris generated during the production process, due to their lighter mass, are easily blown off the surface of the conveyor belt 5 by the airflow, entering the ventilation slot 608, and ultimately falling into the collection hopper 607 connected to the ventilation slot 608. This design allows for the removal of defective and waste materials without the need for any additional power source or testing equipment, not only ensuring the purity of the final product batch but also further reducing labor costs.

[0042] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
