Description

Technical Field

[0001] This utility model relates to the field of high-frequency welding machine technology, specifically to a high-frequency sliding pressure boosting device. Background Technology

[0002] High-frequency welding machines are industrial devices that use high-frequency electromagnetic fields to induce frictional heat in the molecules of materials such as PVC and TPU, achieving welding and sealing. They primarily employ high-frequency equipment with high-voltage rectification and self-excited high-frequency electron tube oscillation to instantaneously generate an electromagnetic wave current field. Within this electromagnetic field, the molecules of the plastic materials being processed undergo polarization and frictional heat generation. Combined with a certain pressure, this achieves the welding and sealing of the plastic products. Existing welding devices, due to space limitations, require a pressurizing device to further increase pressure after the initial pressing operation, thus improving the sealing effect.

[0003] For example, patent document CN202220450450.0, published on September 16, 2022, and classified under B29C65 / 04, discloses a linear module for a high-frequency welding head, including a fixed base, a guide post, and a lead screw. One side of the fixed base has a movable cavity. The lower ends of the guide post and the lead screw extend downwards from the bottom of the fixed base and are connected to the welding head. A connecting piece is screwed onto the lead screw. When the lever linkage mechanism drives the connecting piece to move up and down in the movable cavity, the lead screw also moves up and down. Thus, under the driving action of the lead screw, the welding head can be moved up and down. Furthermore, the guide post enhances the linear guiding effect, improving the accuracy and stability of the up-and-down movement. Additionally, after the lever linkage mechanism controls the welding head to descend and contact the raw material, the operator can screw the lead screw to move it further downwards a short distance, allowing the welding head to press more tightly against the raw material.

[0004] The high-frequency welding machine described in the above literature superimposed the initial pressing process on top of the pressing process. It achieves pressing by rotating the lever mechanism and the rotating component. Since the pressing component needs to be pressed up a long distance by swinging the lever structure, the connection between the rotating component and the lever mechanism is prone to damage due to prolonged stress during long-term use. Furthermore, the force transmission between the lever mechanism and the rotating component is relatively long, and the pressing device can only achieve better pressing by pressing down the lower foot pedal, resulting in poor transmission effect. Because a single lever mechanism is used to achieve both pressing and pressing, the entire pressing mechanism is relatively complex in structure. Utility Model Content

[0005] This invention provides a high-frequency sliding booster device that can stably boost pressure and has a simple structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a high-frequency sliding pressure boosting device is mounted on a frame, and a rotating assembly is rotatably mounted on the frame, including a drive device, a transmission component, an eccentric pin, and an inner diaphragm sleeve. The rotating assembly includes two parallel rotating plates, which are fixedly connected. Each rotating plate has a rotating hole. The transmission component and the inner diaphragm sleeve have first through holes. The eccentric pin is inserted into the first through hole to fix the transmission component and the inner diaphragm sleeve. The eccentric pin passes through the rotating hole and is rotatably connected to the rotating plate. The eccentric pin and the transmission component have the first through hole, and a fixed shaft is installed in the first through hole and the rotating hole.

[0007] The above setup drives the transmission component to rotate via the output of the drive device. The inner diaphragm sleeve and the transmission component are fixedly connected by an eccentric pin, causing the transmission component to drive the inner diaphragm sleeve and the eccentric pin to rotate together. Due to the eccentric setting of the eccentric pin, the rotating plate is instantly pressurized downwards when rotating from a relatively thick area to a thin area. The transmission component and the rotating plate share a fixed shaft, allowing the transmission component to act directly on the rotating plate, reducing the length of the force transmission path. The entire structure is simple, and the eccentric setting on the eccentric pin provides space for the longitudinal movement of the rotating plate, resulting in a good pressurization effect.

[0008] Furthermore, one end of the transmission component is provided with an oblong hole, and the drive device is hinged to the transmission component, with the hinge point sliding within the oblong hole.

[0009] The above configuration, by sliding the hinge of the drive unit and the transmission component in the oblong hole, provides matching space for the longitudinal movement of the rotating plate and prevents the problem of excessive stress concentration at the hinge due to the fixed hinge.

[0010] Furthermore, the inner membrane sleeve includes a first inner membrane sleeve and a second inner membrane sleeve. The first inner membrane sleeve is located on both sides of the transmission component, and a groove recessed towards the center is provided on the outer wall of the eccentric pin. The first through hole of the first inner membrane sleeve and the second inner membrane sleeve are provided with a first groove recessed towards the outer wall at the position of the groove. The first groove and the groove form a cavity, and a pin is provided in the cavity.

[0011] The above configuration involves providing a first groove on the first inner diaphragm sleeve and the second inner diaphragm sleeve, with the first groove and the groove forming a cavity. A pin is placed inside the cavity, thereby enabling the transmission component and the inner diaphragm sleeve to be radially limited by inserting the pin into the cavity.

[0012] Furthermore, the first through hole of the first inner diaphragm sleeve and the second inner diaphragm sleeve are eccentrically positioned with respect to the through hole on the eccentric pin, and the groove on the eccentric pin is positioned on the side of the eccentric pin away from the through hole.

[0013] The above settings include an eccentric through-hole for the eccentric pin, which allows the rotating plate to rotate. The groove on the eccentric pin is offset from the through-hole, making the eccentric pin more stable in its positioning.

[0014] Furthermore, a third connecting plate is fixedly connected between the two rotating plates on the side near the lever linkage mechanism.

[0015] The above configuration enhances the overall rigidity of the rotating plate by fixing two identical plates close to the lever linkage mechanism via a third connecting plate.

[0016] Furthermore, a connecting cover plate, a first connecting plate, and a second connecting plate are provided at one end of the two rotating plates near the pressure application component. The connecting cover plate, the first connecting plate, and the second connecting plate are fixedly connected to the two rotating plates, and the two ends of the connecting cover plate are respectively connected to the upper end surfaces of the two rotating plates.

[0017] The above configuration, by adding a connecting cover plate and first and second connecting plates to the other end of the plate and fixing them to the plate, is equivalent to adding reinforcing ribs to the critical output end, thereby improving the ability of this part to resist bending and deformation.

[0018] Furthermore, the lever linkage mechanism also includes a pedal and a connecting rod. One end of the connecting rod is provided with a connecting post, and the connecting post is provided with a connecting hole. The end of the rotating plate near the connecting rod is provided with a fixing hole corresponding to the connecting hole. The fixing hole and the connecting hole are connected by a fixing post.

[0019] The above configuration, by setting the connecting column to hinge one end of the rotating plate, makes the rotating plate more flexible in the radial direction, saves installation space, and makes the force transmission more direct.

[0020] Furthermore, both the first connecting plate and the second connecting plate are arc-shaped plates, and the first connecting plate is disposed between the two rotating plates and recessed towards the side of the pressure-applying component, the second connecting plate is disposed between the two rotating plates and recessed towards the side away from the pressure-applying component, and the connecting cover plate is disposed between the first connecting plate and the second connecting plate.

[0021] The above configuration uses an arc-shaped first connecting plate that is recessed towards the pressure-applying component, thus providing space for the rotation of the transmission component and the eccentric pin. The second connecting plate is recessed away from the pressure-applying component, thus providing space for the movement of the pressure-applying component. The first and second connecting plates are then connected from the top by a connecting cover plate to prevent deformation of the upper part of the rotating plate.

[0022] Furthermore, a U-shaped groove is provided at the end point of the other end of the rotating plate, and a fixing member is engaged in the U-shaped groove. A pressure fixing hole is provided in the middle of the fixing member. The pressure assembly includes a fixing rod and a pressing member provided at one end of the fixing rod. The fixing rod passes through the pressure fixing hole, and both ends of the fixing member are engaged in the U-shaped groove.

[0023] The above configuration allows for easy connection by using a U-shaped groove on the other end of the rotating plate to engage with the fixing rod of the vertically positioned pressure component. Attached Figure Description

Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

The transmission component 32 and the inner diaphragm sleeve have first through holes. The eccentric pin is inserted into the through hole to fix the transmission component and the inner diaphragm sleeve together. The pin passes through the rotating hole 340 and is rotatably connected to the rotating plate 34. The eccentric pin 331 and the transmission component 32 are provided with a first through hole 338. A fixed shaft 337 is provided in the first through hole 338 and the rotating hole 340. The fixed shaft 337 passes through the frame 1 and is rotatably connected to the frame 1. In this embodiment, the two ends of the fixed shaft 337 are provided with a first fixed ring 335 and a second fixed ring 336. After the fixed shaft 337 passes through the frame 1, the inner membrane sleeve, the rotating hole and the transmission component, the two ends are axially limited by the first fixed ring 335 and the second fixed ring 336 and can be rotatably connected to the frame 1.

[0034] The inner membrane sleeve includes a first inner membrane sleeve 332 and a second inner membrane sleeve 333.

The first through hole 338 of the first inner membrane sleeve 332 and the second inner membrane sleeve 333 is provided with a first groove 3381 recessed towards the outer wall at the position corresponding to the groove 3311. The first groove 3381 and the groove 3311 form a cavity, and a pin 334 is provided in the cavity.

[0035] The first through hole 338 of the first inner membrane sleeve 332 and the second inner membrane sleeve 333 are eccentrically disposed with the through hole 3310 on the eccentric pin 331, and the groove 3311 on the eccentric pin 331 is disposed on the side of the eccentric pin 331 away from the through hole 3310.

[0036] A third connecting plate 363 is fixedly connected between the two rotating plates 34 on the side near the lever linkage mechanism 2.

[0037] A connecting cover plate 35, a first connecting plate 361, and a second connecting plate 362 are provided at one end of the two rotating plates 34 near the pressure application component 37. The connecting cover plate 35, the first connecting plate 361, and the second connecting plate 362 are fixedly connected to the two rotating plates 34. The two ends of the connecting cover plate 35 are respectively connected to the upper end surfaces of the two rotating plates 34.

[0038] like Figure 3 and Figure 4 , Figure 5 and Figure 6 As shown, the lever linkage mechanism 2 includes a pedal 21 and a connecting rod 22. One end of the connecting rod 22 is provided with a connecting post 23, and a connecting hole is provided on the connecting post 23. The rotating plate 34 is provided with a fixing hole 341 corresponding to the connecting hole at one end near the connecting rod. The fixing hole 341 and the connecting hole are connected by a fixing post, thereby enabling the rotating plate 34 and the connecting rod to be hinged.

[0039] like Figure 2 As shown, both the first connecting plate 361 and the second connecting plate 362 are arc-shaped plates. The first connecting plate 361 is disposed between the two rotating plates 34 and is recessed towards one side of the pressure-applying component 37. The second connecting plate 362 is disposed between the two rotating plates 34 and is recessed towards the side away from the pressure-applying component 37. The connecting cover plate 35 is disposed between the first connecting plate 361 and the second connecting plate 362.

[0040] like Figure 2 As shown, a U-shaped groove is provided at the end of the other end of the rotating plate 34. A fixing member 371 is engaged in the U-shaped groove. A pressure fixing hole 370 is provided in the middle of the fixing member 371. The pressure assembly 37 includes a fixing rod 372 and a pressing member 373 provided at one end of the fixing rod 372. The fixing rod 372 is provided through the pressure fixing hole 370, and both ends of the fixing member 372 are engaged in the U-shaped groove.

[0041] The working principle of this utility model is as follows: When the pedal 21 is pressed, the connecting post 23 at one end of the connecting rod 22 is hinged to the rotating plate 34, transmitting the rotational force of the pedal to the rotating plate 34, driving it to complete the same downward pressing action. Then, the pressurization process begins. The output end of the drive device 31 moves downward and connects to the waist-shaped hole at one end of the transmission component 32. The other end of the transmission component 32 applies a downward force to the two plates of the rotating plate 34 through the first inner diaphragm sleeve 332 and the second inner diaphragm sleeve 333. The rotating plate 34 can rotate around its central eccentric pin hole 331. The pin hole is passed through by the pin 334 and clamped on both sides by the first fixing ring 335 and the second fixing ring 336, forming a stable rotation fulcrum. When the transmission component 32 pushes the rotating plate, the rotating plate... The component rotates around the eccentric pin hole 331. Due to the eccentric setting of the eccentric pin 331, the eccentric pin 331 drives the rotating plate 34 to instantly increase pressure downward when rotating from a relatively thick part to a thin part. Moreover, the transmission component 32 and the rotating plate 34 share a fixed shaft, which allows the transmission component 43 to act directly on the rotating plate 34, reducing the length of the force transmission path. The entire structure is simple, and the eccentric setting on the eccentric pin 331 provides space for the rotating plate 34 to move in the longitudinal direction, resulting in a good pressure increase effect.
