Single-sided double-station high-frequency machine

Abstract

This invention provides a single-sided dual-station high-frequency machine, comprising a worktable, a stamping device, and a drive device. Stamping devices are located on both sides of the worktable's front, and the drive device is housed inside the worktable. When the drive device operates, the drive plate moves to one side, causing a transmission column on that side to move backward, raising the first guide wheel of the swing arm and lifting the stamping column on that side. This facilitates the removal of the finished product and the placement of the fabric to be processed. Simultaneously, the transmission column on the opposite side moves forward, driving the first guide wheel of the swing arm to press down, causing the stamping column on the opposite side to descend and perform texture pressing. This linkage mechanism allows the high-frequency vibrating plates of the stamping devices on both sides of the worktable to alternately rise and fall, enabling alternating operation of the two stamping devices. This allows operators to continuously change fabrics while the equipment is running, eliminating the idle time caused by waiting for the pressing cycle in traditional single-station high-frequency machines. This achieves seamless production flow, avoids wasted labor time and production interruptions, and improves equipment utilization and capacity.

Description

Technical Field

[0001] This utility model relates to the field of high-frequency machine structure, and in particular to a single-sided dual-station high-frequency machine. Background Technology

[0002] High-frequency embossing machines are widely used in the field of fabric embossing technology. Existing high-frequency embossing machines typically include a frame, a pressure head, a fabric placement platform, a foot pedal, and a linkage mechanism. The linkage mechanism is housed within the frame, with its upper end connected to the pressure head and its lower end connected to the foot pedal. The fabric placement platform is fixed to the frame, and the pressure head is located directly above it. During operation, the operator places the fabric on the platform and applies pressure by stepping on the foot pedal. Under this pressure, the linkage mechanism drives the pressure head downwards, pressing the fabric down to create the embossed pattern.

[0003] However, such equipment only has a single workstation. During each pressing cycle, the staff must wait for the pressure head to complete pressing and lifting before they can take out the finished product and put in the new fabric. This forced waiting process causes the equipment to frequently enter an idling state, resulting in wasted labor time and interruption of the production process, which seriously restricts the equipment utilization rate and capacity. Utility Model Content

[0004] In view of the shortcomings mentioned above, this utility model provides a single-sided dual-station high-frequency machine.

[0005] The present invention adopts the following technical solution:

[0006] A single-sided dual-station high-frequency machine includes: a worktable, stamping devices provided on both sides of the front of the worktable, and a driving device provided inside the worktable.

[0007] The stamping device includes a fixed base fixed to the worktable and a stamping column restricted to moving vertically on the front of the fixed base, with a high-frequency vibrating plate fixed to the bottom surface of the stamping column;

[0008] The driving device includes:

[0009] Two connecting rods corresponding to the stamping devices on both sides: each connecting rod moves vertically up and down below the corresponding fixed seat, its upper end passes through the fixed seat and is fixedly connected to the stamping column, and its lower end has a horizontal first strip groove.

[0010] Two pivot seats corresponding to the stamping devices on both sides: fixed inside the worktable and located below the corresponding stamping devices;

[0011] Two guide seats corresponding to the stamping devices on both sides: located inside the lower part of the worktable, each guide seat has a vertical second strip groove and a fixed transmission column, and the guide seat slides linearly relative to the pivot seat on the same side;

[0012] Two swing arms corresponding to the stamping devices on both sides: each swing arm is provided with a first guide wheel and a second guide wheel at both ends. The middle part of the swing arm is restricted to pivoting on the pivot seat on the same side. The first guide wheel is slidably embedded in the first slot of the connecting rod on the same side, and the second guide wheel is slidably embedded in the second slot of the guide seat on the same side.

[0013] A drive plate that is horizontally slidably disposed within the worktable: its surface is provided with two mirror-symmetrical inclined guide grooves, and the upper ends of the transmission columns of the two guide seats are slidably embedded in the two guide grooves respectively; the guide grooves extend inclinedly from both sides of the worktable toward its center and back.

[0014] When the drive plate moves to one side of the worktable: the guide groove on that side pushes the transmission column on that side to move to the back of the worktable, driving the first guide wheel of the swing arm on that side to swing upward, causing the connecting rod and the stamping column on that side to rise; at the same time, the guide groove on the opposite side pushes the transmission column on the opposite side to move to the front of the worktable, driving the first guide wheel of the swing arm on the opposite side to swing downward, causing the connecting rod and the stamping column on the opposite side to descend.

[0015] In one possible implementation, a strip-shaped clearance groove is provided on the front of the worktable, the drive plate fixes the operating handle, and the end of the operating handle protrudes from the clearance groove.

[0016] In one possible implementation, two horizontally arranged guide columns are fixed inside the workbench, and two guide sleeves are on both sides of the drive plate. The guide sleeves on both sides of the drive plate are respectively adapted to form a sliding fit with the two guide columns.

[0017] In one possible implementation, a protruding baffle is provided on the front edge of the worktable, and the operating handle is located directly below the baffle.

[0018] In one possible implementation, the stamping device further includes a booster cylinder, which is fixed above the fixed base and has its piston rod pointing downwards. When the stamping column drives the high-frequency vibrating plate to press down on the fabric on the worktable, the piston of the booster cylinder presses down on the top of the stamping column.

[0019] In one possible implementation, the drive device further includes a control system and limit switches. Limit switches are fixed on both sides of the drive plate within the worktable. When the drive plate moves through the guide groove, driving the transmission column to move and causing the high-frequency vibration plate to descend, the drive plate triggers the limit switches. The control system receives the triggered signal from the limit switches and controls the piston rod of the booster cylinder to descend.

[0020] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: When the drive plate moves to one side, it drives the transmission column on one side to move backward, causing the first guide wheel of the swing arm to swing upward, driving the stamping column on one side to rise, making it easier to take out the finished product and put in the fabric to be processed. At the same time, the transmission column on the opposite side moves forward, driving the first guide wheel of the swing arm to press down, driving the stamping column on the opposite side to descend to perform texture pressing. This linkage mechanism enables the high-frequency vibrating plates of the stamping devices on both sides of the worktable to rise and fall alternately, so that when one side is pressing, the other side rises to the pick-up and put-out height simultaneously, thereby realizing the alternating operation of the two stamping devices. This allows the operator to perform uninterrupted fabric changing while the equipment is running continuously, eliminating the idle time caused by waiting for the pressing cycle in traditional single-station high-frequency machines, realizing seamless connection of the production process, avoiding waste of manual time and interruption of the production process, and helping to improve equipment utilization and capacity.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0031] Hereinafter, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0032] Furthermore, in this application, directional terms such as "upper" and "lower" are defined relative to the indicated placement of the components in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the placement of the components in the accompanying drawings.

[0033] This utility model provides a single-sided dual-station high-frequency machine, as shown in the attached figure. Figures 1 to 3 As shown, the high-frequency machine includes a worktable 1, a stamping device 2, and a drive device 3. The stamping devices 2 are installed on both sides of the front of the worktable 1, and the drive device 3 is located inside the worktable 1.

[0034] Please refer to the appendix. Figure 4 The stamping device 2 includes a fixed base 21 and a stamping column 22. The fixed base 21 is fixed to the worktable 1 and has a "7"-shaped structure, extending upwards from its front surface towards the front of the worktable 1. The stamping column 22 vertically passes through the portion of the fixed base 21 extending towards the front of the worktable 1, thus restricting its vertical movement. Preferably, a linear bearing is embedded in the front surface of the fixed base 21, and the stamping column 22 is fitted through this bearing for smooth guidance. A high-frequency vibrating plate 23 is fixed to the bottom surface of the stamping column 22, and a mold is fixed to the bottom surface of the high-frequency vibrating plate 23. The bottom surface of the mold has the desired texture. Additionally, an ultrasonic generator can be configured on the worktable 1. The ultrasonic generator drives a piezoelectric ceramic transducer by outputting a 15-40kHz high-frequency electrical signal, converting electrical energy into mechanical vibration of the same frequency. This vibration is amplified and transmitted to the high-frequency vibrating plate 23, allowing the high-frequency vibrating plate 23 to drive the mold to apply high-frequency impact to the fabric.

[0035] Specifically, during the fabric printing process, the fabric is placed on the worktable 1 at the position corresponding to the high-frequency vibrating plate 23 below it. The driving device 3 then controls the pressing column 22 to descend, causing the high-frequency vibrating plate 23 to descend to the mold at its bottom, pressing against the fabric. The high-frequency vibrating plate 23 generates high-frequency mechanical vibration, which is transmitted to the mold. Under the vibration, the pattern on the bottom of the mold applies high-frequency impact pressure to the fabric. This vibrational energy promotes rapid movement of fabric molecules, generating localized heat and plastic deformation, allowing the surface material of the fabric to precisely fill the grooves in the mold pattern, thus achieving efficient and precise pattern replication. After the specified pressing time, the driving device 3 controls the pressing column 22 to rise again, obtaining the desired pattern.

[0036] As attached Figure 6 and 7 As shown, the driving device 3 includes a connecting rod 31, a pivot seat 32, a guide seat 33, a swing arm 34, and a driving plate 35. Each of the two stamping devices 2 is equipped with a connecting rod 31, a pivot seat 32, a guide seat 33, and a swing arm 34. The connecting rod 31 moves vertically below the corresponding fixed seat 21. Specifically, a vertically arranged first slide rail 361 is fixed within the worktable 1, and a sliding first slider 362 is adapted to connect to the first slide rail 361. The connecting rod 31 is fixed to the first slider 362, allowing the connecting rod 31 to move vertically relative to the fixed seat 21 along the first slide rail 361. The upper end of the connecting rod 31 passes through the fixed seat 21 and is fixedly connected to the stamping column 22. Preferably, the stamping column 22 has a fixed crossbar 311, which extends into the vertical portion within the fixed seat 21 and is fixed to the connecting rod 31, forming a rigid connection between the connecting rod 31 and the stamping column 22. Additionally, a horizontal first slot 312 is formed at the lower end of the connecting column within the worktable 1.

[0037] Both pivot seats 32 are fixed to the lower part of the worktable 1, and both guide seats 33 are located inside the lower part of the worktable 1. The guide seats 33 slide linearly relative to the pivot seats 32 on the same side. The sliding structure can be that a second slide rail 371 is fixed to the bottom of the worktable 1, the second slide rail 371 is adapted to connect to the sliding second slider 372, and the guide seat 33 is fixed above the second slider 372. A vertical second strip groove 331 is opened on the guide seat 33 near the pivot seat 32, and a transmission column 332 is fixed on the end of the guide seat 33 away from the pivot seat 32.

[0038] Please refer to the appendix. Figure 8The swing arm 34 has a first guide wheel 341 and a second guide wheel 342 at both ends. The middle part of the swing arm 34 is restricted to pivoting on the pivot seat 32 on the same side. Specifically, the pivoting connection between the middle part of the swing arm 34 and the pivot seat 32 can be achieved by inserting a pin. In addition, the first guide wheel 341 is slidably embedded in the first slot 312 of the connecting rod 31 on the same side, and the second guide wheel 342 is slidably embedded in the second slot 331 of the guide seat 33 on the same side. In this structure, when the guide seat 33 moves, it can push the second guide wheel 342 to drive the swing arm 34 to swing, so as to pull the connecting rod 31 up or down through the first guide wheel 341 to lift and lower, thereby driving the stamping column 22 to lift and lower.

[0039] As attached Figure 5 and 9 As shown, two horizontally arranged guide columns 381 are fixed inside the worktable 1. Two guide sleeves 382 are located on both sides of the drive plate 35. The guide sleeves 382 on both sides of the drive plate 35 are adapted to slide against the two guide columns 381, thus restricting the horizontal sliding of the drive plate 35 within the worktable 1. The surface of the drive plate 35 is also provided with two mirror-symmetrical inclined guide grooves 351, which extend inclinedly from both sides of the worktable 1 towards its center and back. The upper ends of the transmission columns 332 of the two guide seats 33 are slidably embedded in the two guide grooves 351. Sliding the drive plate 35 allows the guide grooves 351 to push the transmission columns 332, thereby moving the guide seats 33. This, in turn, through the linkage of the swing rod 34 and its two ends—the first guide wheel 341, the second guide wheel 342, and the connecting rod 31—drives the stamping column 22 to rise and fall.

[0040] Specifically, as shown in the appendix Figure 2 and 6 As shown, when the drive plate 35 moves to one side of the worktable 1 (e.g., the left side), the guide groove 351 on that side pushes the transmission column 332 on that side to move towards the back of the worktable 1. This pushes the second guide wheel 342 of the swing rod 34 on that side, thereby driving the swing rod 34 on that side to swing. This causes the first guide wheel 341 of the swing rod 34 on that side to swing upward, and pushes the first strip groove 312 to drive the connecting rod 31 and the stamping column 22 on that side to rise, making it easier for the operator to take out the fabric that has completed the pattern pressing and to place the fabric to be pressed. (Refer to the attached diagram.) Figure 3Simultaneously, the guide groove 351 on the opposite side (e.g., the right side) pushes the transmission column 332 on the opposite side to move towards the front of the worktable 1. This pushes the second guide wheel 342 of the swing rod 34 on the opposite side, causing the swing rod 34 on the opposite side to swing downwards. This swings the first guide wheel 341 of the swing rod 34 on the opposite side, and pushes the first strip groove 312 to drive the connecting rod 31 and the stamping column 22 on that side to descend, causing the connecting rod 31 and the stamping column 22 on the opposite side to press down, thus pressing the fabric at the corresponding position on the right side of the worktable 1. The linkage mechanism of this drive device 3 realizes the core function of alternating lifting and lowering of the two-sided stamping devices 2. When one side of the high-frequency vibration plate 23 is in the pressing position, the other side of the high-frequency vibration plate 23 rises synchronously to the pick-up and drop position. This design completely eliminates the downtime caused by waiting for the pressing cycle in traditional equipment. Operators can continuously perform fabric pick-up and drop operations on the other position during the pressing process of any stamping device 2, forming a continuous cycle production process, which significantly improves the overall working efficiency and production efficiency of the equipment.

[0041] Furthermore, a strip-shaped clearance groove 101 is provided on the front of the worktable 1, and the drive plate 35 fixes the operating handle 352, with the end of the operating handle 352 protruding from the clearance groove 101. During operation, pushing the operating handle 352 on the front of the worktable 1 will cause the drive plate 35 to slide, thereby realizing the alternating lifting and lowering of the high-frequency vibrating plates 23 of the two stamping devices 2. Even further, a protruding baffle is provided on the edge of the front of the worktable 1, and the operating handle 352 is located directly below the baffle, thereby preventing the operator from accidentally touching the operating handle 352 when walking on the front of the worktable 1.

[0042] Continue to refer to the appendix Figure 2 and 3 The stamping device 2 also includes a pressure booster cylinder 24, which is fixed above the fixed base 21, with its piston rod 241 pointing downwards. When the stamping column 22 drives the high-frequency vibration plate 23 to press down onto the fabric on the worktable 1 to complete the initial pressing, the piston rod 241 of the pressure booster cylinder 24 simultaneously presses down against the top of the stamping column 22, applying secondary pressure to the high-frequency vibration plate 23. This design significantly enhances the pressing strength of the mold on the fabric through mechanical pressure supplementation, ensuring that the high-frequency vibration energy deeply penetrates the fabric fiber layer, enhancing the clarity and three-dimensionality of the texture transfer, while avoiding pressing defects caused by uneven fabric thickness, thus greatly improving the stability of the finished product quality.

[0043] The drive unit 3 also includes a control system (not shown in the attached diagram) and a limit switch 39. The control system can be a PLC controller, and it responds to the trigger signal of the limit switch 39 in real time and precisely controls the action of the booster cylinder 24. (See attached diagram for further details.) Figure 9Limit switches 39 are fixed on both sides of the drive plate 35 inside the workbench 1. When the drive plate 35 moves through the guide groove 351, driving the transmission column 332 to move and causing the high-frequency vibrating plate 23 to descend, the drive plate 35 simultaneously presses the contact of the limit switch 39 on the same side. The control system immediately receives the trigger signal and drives the piston rod 241 of the booster cylinder 24 to press down. Conversely, when the drive plate 35 moves in the opposite direction and disengages from the contact of the limit switch 39, the control system responds to the release signal and immediately controls the piston rod 241 to rise. This linkage control mechanism realizes automatic response of the boosting action, ensuring that the boosting pressure is accurately matched with the pressing phase of the high-frequency vibrating plate 23. This avoids mechanical impact caused by premature boosting and eliminates energy loss caused by delayed depressurization, which is beneficial to improving equipment operating efficiency.

[0044] In summary, in the driving device 3 of this utility model, when the driving plate 35 moves to one side, it drives the transmission column 332 on one side to move backward, causing the first guide wheel 341 of the swing arm 34 to swing upward, driving the stamping column 22 on one side to rise, making it easier to remove the finished product and put in the fabric to be processed. At the same time, the transmission column 332 on the opposite side moves forward, driving the first guide wheel 341 of the swing arm 34 to press down, driving the stamping column 22 on the opposite side to descend to perform texture pressing. This linkage mechanism causes the high-frequency vibration plates 23 of the stamping devices 2 on both sides of the worktable 1 to rise and fall alternately, so that when one side is pressing, the other side rises to the pick-up and put-out height simultaneously, thereby realizing the alternating operation of the two stamping devices 2. This allows the operator to perform uninterrupted fabric changing while the equipment is running continuously, eliminating the idle time caused by waiting for the pressing cycle in traditional single-station high-frequency machines, realizing seamless connection of the production process, avoiding waste of manual time and interruption of the production process, and helping to improve equipment utilization and capacity.

[0045] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto. Any non-substantial modifications made to this utility model using this concept shall be considered as an infringement of the protection scope of this utility model.
