Description

Technical Field

[0001] This utility model relates to the technical field of high-frequency fusing equipment, specifically a high-frequency automatic rotary fusing machine. Background Technology

[0002] A high-frequency fusing machine is a device that uses the principle of high-frequency electromagnetic fields to process materials. It generates a high-frequency electromagnetic field through a high-frequency generator, which causes the molecules inside materials such as plastic, leather, and cloth placed between electrode plates to generate intense friction and heat, thereby achieving the fusing of the material. It can be combined with automated feeding and unloading equipment and control systems to achieve efficient and continuous automated production.

[0003] A search revealed that Chinese patent application number CN202321307239.4 discloses a high-frequency disc fuser, comprising a cabinet, a base, and a top shell. The base is installed on the top of the cabinet, and a lower electrode plate is installed inside the base. The top of the lower electrode plate is equipped with a fixing structure, and an upper electrode plate is installed at the bottom of the buffer structure. A grounding copper sheet is installed on one side of the upper electrode plate. The fixing structure includes fixing bolts, screw grooves, fixing plates, brackets, pull rods, compression springs, and pressure plates. The screw grooves are all opened inside the top of the lower electrode plate, and fixing bolts are inserted into the screw grooves. Fixing plates are sleeved on the outside of the fixing bolts.

[0004] The above-mentioned technical solutions and traditional rotary high-frequency fusing equipment still have shortcomings, such as low operational safety, lack of fully enclosed protection in the high-frequency processing area, easy exposure of operators to high-frequency electric fields (electric field strength ≥100V / m), and the possibility of accidental hand contact with the pressing mold, resulting in a high risk of pinching injury.

[0005] Therefore, we need to propose a high-frequency automatic rotary fusing machine. Utility Model Content

[0006] The purpose of this invention is to provide a high-frequency automatic rotary fusing machine. By equidistantly surrounding the top edge with transparent PC protective plates, it is convenient for operators to observe the operation of the equipment. The gaps between adjacent protective plates also limit the working area, preventing operators from being exposed to a large area of ​​high-frequency electric field. A safety light curtain is installed inside the gap. If a hand enters the light curtain area, the pressing power of the equipment is immediately cut off, effectively preventing accidental contact with the pressing mold and greatly reducing the risk of pinching injury, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] High-frequency automatic rotary fusing machine, including:

[0009] The machine body includes a base and a support arm, with the support arm provided on one side of the base;

[0010] A rotating mechanism is provided on the top of the base. The rotating mechanism includes a turntable and a surrounding edge. The surrounding edge is provided on the top surface of the base. The turntable is rotatably mounted on the base inside the surrounding edge. A workstation is provided on the turntable, and a template is fixed on the workstation.

[0011] A fusing mechanism is located at the bottom of the support arm and corresponds to the work station. The fusing mechanism includes a high-frequency generator and an electrode plate. The high-frequency generator is driven to lift by a cylinder, and the electrode plate is installed on one side of the high-frequency generator.

[0012] Preferably, a servo motor is installed inside the base to drive the turntable to rotate and thus switch work positions, and a cylinder is installed inside the support arm to drive the high-frequency generator to lift and lower and thus perform the fusing operation.

[0013] Preferably, it also includes a protective mechanism, which is set on the top of the perimeter. The protective mechanism includes several sets of protective plates. The protective plates are transparent PC plates with a thickness of 3mm. The protective plates are equidistantly arranged around the top of the perimeter, and the gaps between adjacent protective plates correspond to a set of workstations. The gaps allow users to put their hands in to perform operations.

[0014] Preferably, a safety light curtain is installed in the notch of the adjacent protective plate. The safety light curtain includes a transmitter and a receiver. The transmitter and receiver are respectively fixed to the end face of the adjacent protective plate. When a hand enters the light curtain area, the pressing power of the equipment is immediately cut off.

[0015] Preferably, the safety light curtain is provided with a mounting plate, and the end face of the protective plate is provided with a protruding plate. The mounting plate and the protruding plate are fixed together by fixing screws.

[0016] Preferably, it also includes a positioning mechanism for positioning the template. The positioning mechanism includes a positioning groove disposed on the template and a threaded rod and a positioning block disposed on the turntable. The positioning block and the positioning groove are adapted to each other, and the positioning block is driven by the threaded rod.

[0017] Preferably, bearing seats are provided on both sides of the workstation on the turntable, and the lower end of the threaded rod is inserted and fixed to the inner ring of the bearing seat. One end of the positioning block is threadedly engaged with the threaded rod. When the threaded rod rotates, it can drive the positioning block to rise and fall, thereby engaging or disengaging from the positioning groove. The threaded rod is driven to rotate by the rocker arm at the upper end.

[0018] Preferably, the threaded rod is provided with a keyway at the top, and a convex key is provided at the bottom of one end of the rocker arm. The rocker arm and the threaded rod are connected by a keyway and then the threaded rod is rotated by the rocker arm.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The transparent PC protective panel at the top of the perimeter forms a ring-shaped closed structure, retaining the necessary operating space only through the gap. The insulation properties of the PC panel can shield high-frequency electric fields, avoiding long-term exposure of operators to high-frequency radiation. At the same time, the transparent material does not affect the observation of the processing process.

[0021] 2. The safety light curtain at the gap (installed correspondingly at the transmitter and receiver) forms an invisible protective barrier. When a hand enters the working area, the pressing force is immediately cut off. Combined with the physical isolation of the protective plate, the risk of accidental pinching is greatly reduced. In addition, the light curtain is detachably connected to the mounting plate and the protruding plate, which facilitates later maintenance. Attached Figure Description

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-2 This utility model provides a technical solution:

[0029] High-frequency automatic rotary table 3-fuse machine, including:

[0030] The machine body includes a base 1 and a support arm 2, with the support arm 2 located on one side of the base 1. A rotating mechanism is located on top of the base 1, comprising a turntable 3 and a surrounding edge 4. The surrounding edge 4 is located on the top surface of the base 1, and the turntable 3 is rotatably mounted on the base 1 within the surrounding edge 4. A workstation is set on the turntable 3, and a template 7 is fixed on the workstation. A fusing mechanism is located at the bottom of the support arm 2, corresponding to the workstation. The fusing mechanism includes a high-frequency generator 5 and an electrode plate 6. The high-frequency generator 5 is driven to rise by a cylinder, and the electrode plate 6 is installed on one side of the high-frequency generator 5. A servo motor is installed inside the base 1 to drive the turntable 3 to rotate, thereby switching workstations. A cylinder is installed inside the support arm 2 to drive the high-frequency generator 5 to rise and fall, thereby performing the fusing operation.

[0031] The base 1 supports the fusing mechanism via the support arm 2. The turntable 3 rotates within the perimeter 4, driven by a servo indexing motor (positioning accuracy ±0.02mm). The bottom of the turntable 3 is equipped with an annular guide rail and a wear-resistant slider (friction coefficient ≤0.1) to ensure radial runout ≤0.03mm during rotation, enabling station switching. The cylinder of the fusing mechanism drives the high-frequency generator 5 to rise and fall (stroke 50-100mm). The electrode plate 6 performs fusing processing on the workpiece on the station template 7 under the action of a high-frequency electric field (pressure adjustable from 500-2000N).

[0032] Functions: The surrounding edge 4 forms a boundary constraint for the rotation of the turntable 3, preventing the workpiece from falling; the template 7 provides a reference positioning surface for the workpiece, ensuring the consistency of the melting position; the cylinder-driven melting mechanism can be adapted to workpieces of different thicknesses through pressure adjustment, replacing manual pressing and reducing the frequency of hand entry into the processing area.

[0033] Please see Figures 1-2 :

[0034] It also includes a protective mechanism, which is set on the top of the perimeter 4. The protective mechanism includes several sets of protective plates 8. The protective plates 8 are transparent PC boards with a thickness of 3mm. The protective plates 8 are equidistantly arranged around the top of the perimeter 4, and the gaps between adjacent protective plates 8 correspond to a set of workstations. The gaps allow users to put their hands in to perform operations.

[0035] A 3mm thick transparent PC protective plate 8 is installed around the top of the edging 4. It uses the insulating properties of PC material (dielectric constant 3.0-3.2) to shield high-frequency electric fields and has a high electric field strength attenuation rate. The gaps between adjacent protective plates 8 correspond to only a single workstation, limiting the range of hand access.

[0036] The high-frequency electric field intensity in the processing area is reduced to avoid long-term exposure of operators to radiation; the transparency (transmittance ≥90%) does not affect the observation of the processing status; the notch design reduces the blind spot of protection while meeting the loading / unloading operations (the opening area is only a small part of the traditional unprotected design).

[0037] For a preferred embodiment, please refer to Figures 1-2 :

[0038] A safety light curtain 9 is installed in the notch of the adjacent protective plate 8. The safety light curtain 9 includes a transmitter and a receiver, which are respectively fixed to the end face of the adjacent protective plate 8. The pressing force of the equipment is immediately cut off when a hand enters the light curtain area. A mounting plate 11 is provided on the safety light curtain 9, and a protruding plate 10 is provided on the end face of the protective plate 8. The mounting plate 11 and the protruding plate 10 are fixed together by fixing screws.

[0039] The transmitter and receiver of the safety light curtain 9 are fixed on both sides of the notch in the protective plate 8, forming an infrared detection light curtain. When a hand blocks the light curtain, the sensor sends a signal to cut off the cylinder power source of the fuse mechanism. The mounting plate 11 and the protruding plate 10 are fixed with screws to ensure the stability of the light curtain position.

[0040] The non-contact detection enables dynamic protection by stopping the machine immediately upon hand entry, reducing the risk of accidental pinching injuries; the detachable installation structure facilitates grating calibration or replacement, avoiding false alarms caused by grating misalignment.

[0041] In this embodiment, the following design can be implemented:

[0042] Safety light curtain 9 (model: Sick C2C series), the transmitter and receiver are connected to the PLC controller (Siemens S7-1200) via shielded cables; emergency stop relay (Schneider RXM4AB2P7) is used to cut off the power supply to the cutting equipment.

[0043] The control logic is as follows:

[0044] The transmitter continuously emits an infrared beam, and the receiver monitors in real time whether the beam is blocked. When a foreign object (such as a finger) blocks the beam for ≥20ms, the receiver outputs a high-level signal to the PLC's digital input module (SM1223). The PLC executes an interrupt program, which drives the emergency stop relay through the digital output module (SM1222) to cut off the power supply to the cutting equipment motor (response time ≤50ms).

[0045] For a preferred embodiment, please refer to Figures 1-4 :

[0046] It also includes a positioning mechanism for positioning the template 7. The positioning mechanism includes a positioning groove 12 on the template 7 and a threaded rod 13 and a positioning block 14 on the turntable 3. The positioning block 14 is adapted to the positioning groove 12 and is driven by the threaded rod 13. Bearing seats 15 are provided on both sides of the workstation on the turntable 3. The lower end of the threaded rod 13 is inserted and fixed to the inner ring of the bearing in the bearing seat 15. One end of the positioning block 14 is threadedly engaged with the threaded rod 13. When the threaded rod 13 rotates, it can drive the positioning block 14 to rise and fall, thereby engaging or disengaging from the positioning groove 12. The threaded rod 13 is driven to rotate by the rocker arm 16 at the upper end. A keyway 17 is provided at the top of the threaded rod 13, and a protruding key is provided at the bottom of one end of the rocker arm 16. The rocker arm 16 and the threaded rod 13 are keyed together and then rotated by the rocker arm to drive the threaded rod 13 to rotate.

[0047] The rocker arm 16 engages with the keyway 17 of the threaded rod 13 via a convex key. When the rocker arm 16 is rotated, the threaded rod 13 rotates along the inner ring of the bearing seat 15, driving the positioning block 14 to rise and fall along the thread. After the positioning block 14 is engaged in the positioning groove 12 of the template 7, the displacement of the template 7 is restricted by mechanical engagement.

[0048] To prevent the template 7 from shifting under the rotation of the turntable 3 or the action of the melting pressure, and to reduce the need for manual adjustment due to workpiece misalignment; the keyed rocker arm 16 can be disassembled at any time to avoid interfering with the processing operation; the bearing seat 15 supports and ensures that the threaded rod 13 rotates smoothly, and a single person can complete the positioning operation.

[0049] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
