Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, and in particular to a high-temperature transfer printing machine for air spring bladder skin. Background Technology

[0002] With the rapid development of the automotive industry, the continuous advancement of related technologies, and the constant improvement of residents' living standards, vehicle safety and ride comfort have become core considerations for consumers when purchasing vehicles. Air springs, as a key damping component in automotive suspension systems, can effectively attenuate vibrations caused by road surface undulations during vehicle operation, significantly improving ride comfort, and are therefore widely used in the automotive field.

[0003] The air spring bladder is a core functional component of the air spring, and its molding quality directly determines the overall performance and service life of the air spring. In the actual production process of air spring bladders, defects such as insufficient glue and exposed threads are prone to occur during the vulcanization molding stage. Additionally, the finished bladders need to undergo customized label transfer processing according to customer requirements.

[0004] To address the aforementioned defects in the air spring's molding process, existing technologies typically employ a method of returning defective products to the mold for secondary vulcanization (i.e., product re-molding). While this method can partially compensate for defects such as insufficient glue or exposed threads, it suffers from insurmountable technical flaws. Specifically, the secondary vulcanization process easily leads to over-vulcanization of the air spring's rubber matrix. Over-vulcanization significantly reduces the elasticity and stretching properties of the rubber material, severely degrading its durability and aging resistance. This not only results in a substantial decline in product quality but also directly impacts the performance and service life of the air spring. Furthermore, the re-molding and secondary vulcanization process is cumbersome and has a long production cycle, causing a sharp drop in production line capacity. Moreover, this process cannot simultaneously complete the transfer of customer labels, requiring an additional independent process, further reducing production efficiency and increasing manufacturing costs. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature transfer printing machine for air spring bladders.

The outer wall of the receiving post is provided with a threaded part, and the fixing ring is threadedly connected to the outer wall of the receiving post.

[0011] As a further embodiment of the present invention: the auxiliary stabilizing mechanism includes two rotating shafts, two rotating supports, two clamping rollers, a drive assembly, and two clamping frames; wherein, the two clamping rollers are respectively located on both sides of the processing station, and the two clamping rollers are respectively coaxially connected to the two rotating shafts, the two rotating shafts are respectively opposite to the two rotating supports, the two clamping frames are respectively opposite to the two rotating supports, and the drive assembly is used to drive the two clamping frames to move synchronously relative to each other; The rotating support includes a shaft frame and a connecting plate.

[0012] Meanwhile, the clamping frame includes two vertical rods, a second connecting plate, an extension plate, a stabilizing plate, two guide rods, and two second guide sleeves; The two vertical rods correspond to the two shaft brackets respectively. The shaft brackets are provided with bolt holes, and the corresponding vertical rods are provided with elongated holes. When the vertical rods are connected to the shaft brackets, the vertical rods are fixedly connected to the shaft brackets by passing through the bolt holes and elongated holes with a fixing bolt assembly. The two ends of the connecting plate 2 are respectively connected to two vertical rods. The two guide sleeves 2 are both connected to the connecting plate 2. The two guide rods are respectively passed through the two guide sleeves 2, and the guide rods are slidably connected to the corresponding guide sleeves 2. A motor mounting bracket is connected to the frame. The stabilizing plate is connected to the motor mounting bracket. One end of each of the two guide rods is fixedly connected to the stabilizing plate. The extension plate is fixedly connected to the connecting plate 2.

[0021] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0022] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] A high-temperature transfer printing machine for air spring bladder skin, such as Figures 1-11 As shown, it includes: frame 1, electrical control box 2, textured mold 3, lifting mechanism 6, lower mold pad 9, and auxiliary stabilizing mechanism 11; Specifically, the frame 1 has an open working station 4, and the frame 1 is the rigid load-bearing base of the whole machine, which adopts a frame structure welded from steel profiles. The electrical control box 2 is detachably connected to the frame 1 by bolts. The electrical control box 2 has a PLC control system and a human-machine interface operation panel, specifically a programmable controller, a multi-channel independent temperature control module, a time relay, a pneumatic control circuit, and a servo motor drive module. There are at least two textured molds 3, both located at the working station 4. The at least two textured molds 3 are equidistant along a straight line, and there is a gap between two adjacent textured molds 3 to form a safety interval 5. Each textured mold 3 is equipped with a corresponding elevator. The machine consists of a lifting mechanism 6 mounted on the frame 1, with its movable end connected to a heating component 7 via a quick-release assembly 8. The textured mold 3 is mounted on the heating component 7. The lifting mechanism 6 drives the textured mold 3 to reciprocate longitudinally along the working station 4. A lower mold pad 9 is mounted on the frame 1, with a lower mold pad 9 positioned below each textured mold 3. The lower mold pad 9 is longitudinally opposite to the textured mold 3, and a processing station 10 for placing the workpiece is formed between each textured mold 3 and its corresponding lower mold pad 9. An auxiliary stabilizing mechanism 11 is mounted on the frame 1, with an auxiliary stabilizing mechanism 11 corresponding to each processing station 10. The auxiliary stabilizing mechanism 11 is used to stabilize the workpiece located within the processing station 10.

[0024] To enhance the safety protection function of this device, multiple safety protection functions are built into the electrical control box 2, including over-temperature alarm, overload protection, abnormal pressure alarm, and safety door interlock. When situations such as excessive temperature, abnormal cylinder pressure, or safety door opening occur, the equipment operation can be stopped immediately and an alarm can be triggered, fundamentally avoiding equipment failure and safety accidents.

[0025] To facilitate the placement of workpieces, a placement box 56 is provided on workstation 4, which can be used to place workpieces before and after processing, providing convenience for workers.

[0026] Each lower mold pad 9 is fixed to the frame 1 by the support beam 12, and the lower mold pad 9 is detachably connected to the support beam 12 by bolt mechanism. The side of the lower mold pad 9 and the textured mold 3 facing the processing station 10 are both designed with an arc-shaped structure that matches the shape of the workpiece.

[0027] Each lifting mechanism 6 includes a telescopic cylinder 13 and a guide sleeve 14. The telescopic cylinder 13 and the guide sleeve 14 are both mounted on the frame 1. The movable end of the telescopic cylinder 13 extends through the guide sleeve 14 into the working position 4, and the movable end of the telescopic cylinder 13 is slidably connected to the guide sleeve 14. When the electrical control box 2 issues a downward command, the pneumatic control circuit controls the piston rod of the telescopic cylinder 13 to extend at a constant speed and move vertically downward along the inner hole of the guide sleeve 14, driving the heating component 7 and the textured mold 3 to descend synchronously. When the set pressing stroke is reached, the telescopic cylinder 13 stops moving and maintains a constant pressing pressure, entering the pressure holding state. When the pressure holding time is reached, the pneumatic control circuit controls the piston rod to retract at a constant speed, driving the heating component 7 and the textured mold 3 to move vertically upward to reset, completing one pressing cycle. Specifically, the guide sleeve 14 radially limits the extension and retraction of the piston rod, preventing radial wobble and ensuring coaxiality during the lifting and lowering process. The alignment accuracy of the textured mold 3 and the lower mold pad 9 is ±0.1mm. The self-lubricating copper sleeve reduces frictional resistance, eliminating the need for additional lubrication and preventing oil contamination of the bladder workpiece. The electrical control box 2 precisely controls the piston rod's extension speed, downward stroke, and holding pressure, adapting to the pressing process requirements of bladders of different thicknesses and materials. The heating assembly 7 includes a heat insulation plate 15, a heating panel 16, and a heating copper plate 17. The textured mold 3 is connected to the heating copper plate 17. The heat insulation plate 15 is connected to the side of the heating copper plate 17 away from the textured mold 3. The heating panel 16 is connected to the side of the heat insulation plate 15 away from the heating copper plate 17. The heating panel 16 is electrically connected to the control box 2. After the equipment is started, the control box 2 controls the heating copper plate 17 to be energized and heated according to the set process temperature. The heating panel 16 collects the actual temperature of the heating copper plate 17 in real time and feeds it back to the control box 2. When the actual temperature is lower than the set value, the control box 2 controls the heating copper plate 17 to continue heating. When the actual temperature reaches the set value, the control box 2 controls the heating copper plate 17 to enter a pulse heat preservation mode, stabilizing the temperature of the heating copper plate 17 within the set value ±1℃ range. The heat from the heating copper plate 17 is evenly transferred to the textured mold 3 through surface contact, maintaining a constant process temperature on the working surface of the textured mold 3, providing stable heat energy for the bonding and transfer of rubber during the pressing process.

[0028] The quick-installation assembly 8 includes a connecting flange 18, a mating post 19, a receiving post 20, a pin block 21, an abutment post 22, a telescopic spring 23, and a retaining ring 24; The connecting column 19 is fixedly connected to the connecting flange 18, which is detachably connected to the heating panel 16 via bolts. The receiving column 20 is fixedly connected to the movable end of the telescopic cylinder 13. The receiving column 20 has an inwardly axially formed connecting groove 25 at one end near the connecting column 19. Several fixing grooves 26 are equidistantly formed on the inner side wall of the connecting groove 25 around its axis. Each fixing groove 26 is provided with a pin 21, a telescopic spring 23, and an abutting column 22. The pin 21 passes through the fixing groove 26 and is slidably connected to the fixing groove 26. The abutting column 22 is fixedly connected to one end of the pin 21 located inside the fixing groove 26. The telescopic spring 23 is connected between the pin 21 and the fixing groove 26 and is sleeved on the outside of the abutting column 22. The end of the abutting column 22 away from the pin 21 extends through the fixing groove 26 to the outside of the receiving column 20. The outer wall of the docking post 19 is provided with a snap-fit ​​groove 27 corresponding to the fixing groove 26. The end of the pin block 21 away from the abutting post 22 extends to the outside of the fixing groove 26 and engages with the snap-fit ​​groove 27. The outer wall of the receiving post 20 is provided with a threaded part 28. The fixing ring 24 is threaded to the outer wall of the receiving post 20. The heating component 7 can be quickly replaced using the quick-release assembly 8, which facilitates the later maintenance of the heating component 7. When the docking post 19 docks with the receiving post 20, the pin block 21 is squeezed back into the fixing groove 26, and the telescopic spring 23 is squeezed and accumulates spring. When the pin 21 moves to the corresponding snap-fit ​​groove 27, the pin 21 loses external pressure, the telescopic spring 23 releases its elastic force, and the pin 21 snaps into the snap-fit ​​groove 27. Then, the fixing ring 24 is rotated, and the fixing ring 24 moves axially along the receiving column 20 until it stops at the abutting column 22. At this time, the fixing ring 24 limits the abutting column 22, so that the pin 21 is stably snapped into the snap-fit ​​groove 27, thereby forming a stable fixed relationship between the receiving column 20 and the connecting column 19, while the heating component 7 is fixed on the movable end of the telescopic cylinder 13. Specifically, the mating post 19 is aligned with the mating groove 25 of the receiving post 20 and pushed upwards. The top end face of the mating post 19 presses against the outer inclined surface of the pin block 21, causing the pin block 21 to retract into the fixing groove 26 against the elastic force of the telescopic spring 23, until the mating post 19 is fully inserted into the mating groove 25. At this time, the outer end of the pin block 21 is aligned with the snap-fit ​​groove 27, and the telescopic spring 23 releases its elastic force to push the pin block 21 outwards and snap into the snap-fit ​​groove 27, completing the initial axial positioning of the mating post 19 and the receiving post 20. Then, the fixing ring 24 is rotated so that it screws downwards along the external thread 28 of the receiving post 20, and the tapered guide of the fixing ring 24... The outer end of the abutment post 22 is gradually pressed towards the surface, causing the abutment post 22 to drive the pin block 21 to further press into the locking groove 27, completely eliminating the fit gap. At the same time, the fixing ring 24 forms a radial lock on the abutment post 22, preventing the pin block 21 from retracting and loosening during equipment operation, thus achieving a gapless rigid connection between the heating component 7 and the telescopic cylinder 13. Disassembly process: Rotate the fixing ring 24 in the opposite direction to make it move upward, releasing the limit on the abutment post 22. Pull the heating component 7 downward, causing the pin block 21 to retract against the elastic force of the telescopic spring 23, so that the docking post 19 can be quickly pulled out from the docking groove 25, completing the disassembly of the heating component 7.

[0029] The auxiliary stabilizing mechanism 11 includes two rotating shafts 29, two rotating supports 30, two clamping rollers 31, a drive assembly, and two clamping frames 32. The two clamping rollers 31 are located on both sides of the processing station 10, and the two clamping rollers 31 are coaxially connected to the two rotating shafts 29. The two rotating shafts 29 correspond to the two rotating supports 30, and the two clamping frames 32 correspond to the two rotating supports 30. The drive assembly is used to drive the two clamping frames 32 to move synchronously relative to each other. The rotating bracket 30 includes a shaft bracket 33 and a connecting plate 34. Each rotating shaft 29 has a shaft bracket 33 at both ends, and the rotating shaft 29 is rotatably connected to the shaft bracket 33. The two ends of the connecting plate 34 are fixedly connected to the two shaft brackets 33 respectively.

[0030] The clamping frame 32 includes two vertical rods 35, a connecting plate 36, an extension plate 37, a stabilizing plate 38, two guide rods 39, and two guide sleeves 40; Two vertical rods 35 correspond to two shaft brackets 33 respectively. Bolt holes are provided on the shaft brackets 33, and elongated holes 41 are provided on the corresponding vertical rods 35. When the vertical rods 35 are connected to the shaft brackets 33, the vertical rods 35 and shaft brackets 33 are fixedly connected by passing through the bolt holes and elongated holes 41 with the fixing bolt assembly 42. The bolt assembly includes fixing bolts and fixing nuts of the corresponding type. The fixing bolts are threaded to the tails of the fixing bolts. When it is necessary to adjust the height of the rotating shaft 29 and the clamping roller 31, the rotating bracket 30 can be moved by simply loosening the fixing bolt assembly 42. During the movement of the rotating bracket 30, the fixing bolts move in the elongated holes 41. After the rotating bracket 30 moves to the appropriate height, the fixing nuts are tightened again to fix the shaft brackets 33 to the vertical rods 35. That is, the rotating bracket 30 and the clamping frame 32 are in a fixed state. The two ends of the connecting plate 36 are respectively connected to the two vertical rods 35. The two guide sleeves 40 are both connected to the connecting plate 36. The two guide rods 39 are respectively passed through the two guide sleeves 40, and the guide rods 39 are slidably connected to the corresponding guide sleeves 40. The frame 1 is connected to the motor mounting bracket 43. The stabilizing plate 38 is connected to the motor mounting bracket 43. One end of each of the two guide rods 39 is fixedly connected to the stabilizing plate 38. The extension plate 37 is fixedly connected to the connecting plate 36.

[0031] The drive assembly includes a rack 44, a gear 45, a drive shaft 46, and a drive motor 47; Each clamping frame 32 has a rack 44 fixedly connected to its extension plate 37. The teeth of the two racks 44 are opposite each other. A gear 45 is located between the two racks 44, and both racks 44 mesh with the gear 45. The drive motor 47 is mounted on the motor mounting bracket 43. The drive shaft 46 is coaxially connected to the gear 45. The drive shaft 46 is rotatably connected to the stabilizing plate 38 through the rotating base. The output end of the drive motor 47 is connected to one end of the drive shaft 46. In use, the auxiliary stabilizing mechanism 11 includes a drive assembly comprising two racks 44, a gear 45, a drive shaft 46, and a drive motor 47. The two racks 44 are horizontally welded to opposite sides of the extension plates 37 of the two clamping frames 32. The gear 45 is located between the two racks 44 and meshes with both racks simultaneously. The drive motor 47 is a servo motor with a brake, fixed to a motor mounting bracket 43. Its output end is coaxially connected to the drive shaft 46 via a coupling. The drive shaft 46 is rotatably connected to the stabilizing plate 38 via a bearing with a mounting seat. The gear 45 is keyed to... When the control box 2 issues a clamping command, the drive motor 47 rotates in the forward direction on the drive shaft 46, driving the gear 45 to rotate synchronously through the drive shaft 46. The gear 45 drives the two meshing racks 44 to move synchronously relative to each other, thereby driving the two clamping frames 32 to move synchronously towards the center of the processing station 10 along the guide rod 39 until the two clamping rollers 31 are tightly attached to the outer surfaces of both sides of the workpiece. The drive motor 47 then stops rotating and activates the brake to lock. When the release command is issued, the drive motor 47 rotates in the reverse direction, driving the two clamping frames 32 to move synchronously in opposite directions, releasing the clamping of the workpiece. After the workpiece is placed in place, the auxiliary stabilizing mechanism 11 automatically performs the clamping action. The two clamping rollers 31 synchronously fit against the outer circular surfaces of both sides of the workpiece, forming a symmetrical radial clamping force. During the pressing process, the clamping rollers 31 can restrict the axial movement and circumferential rotation of the workpiece, ensuring that the processing position of the textured mold 3 and the workpiece is completely aligned. When the workpiece is unloaded or loaded, the rotating bracket 30 can drive the clamping rollers 31 to rotate freely around the axis of the rotating shaft 29, adapting to the rotation of the workpiece and changing the angle, thus avoiding scratching the surface of the workpiece.

[0032] Each safety interval 5 is provided with a partition plate 48, and the partition plate 48 is fixedly connected to the frame 1. The partition plate 48 is provided with a blower assembly. An air pump 49 is installed on the frame 1. The air pump 49 is connected to the blower assembly through a telescopic hose 50. The blower assembly is used to guide the high-pressure airflow output by the air pump 49 to the processing station 10.

[0033] The air blowing assembly between the input ends includes a linear slide 51, a sliding block 52, a rotating bracket 30, a rotating nozzle 53, and a connecting pipe 54; The linear slide 51 is connected to the partition plate 48, the sliding block 52 is slidably connected to the linear slide 51, and the two sides of the sliding block 52 are fixedly connected to the rotating brackets 30.

The output ends of the rotating air nozzles 53 face the processing station 10. Electric valves 55 are provided at the two output ends of the connecting pipe 54. The input end of the connecting pipe 54 is connected to the output end of the telescopic hose 50. When the processing pressure holding time ends, the lifting mechanism 6 drives the textured mold 3 to move upward and reset. The electrical control box 2 automatically opens the electric valve 55, and the high-pressure airflow output by the air pump 49 is delivered to the rotary air nozzle 53 through the telescopic hose 50 and connecting pipe 54. The high-speed airflow is sprayed onto the processing area of ​​the skin, providing forced air cooling to the area that has just completed vulcanization bonding and transfer. After the air cooling time is reached, the electrical control box 2 automatically closes the electric valve 55, stopping the airflow. The operator can adjust the horizontal position of the sliding block 52 along the straight slide 51 according to the processing position of the skin, while simultaneously rotating the rotary air nozzle 53 to adjust the airflow angle, ensuring that the airflow completely covers the processing area.

[0034] like Figures 1-11 As shown, in this embodiment, when in use, the operator sets the heating temperature of the corresponding processing unit for the rubber material of the skin to be processed through the human-machine interface panel of the control box 2. At the same time, according to the curvature of the skin, the operator changes the appropriate texture mold 3 and the lower mold pad 9, adjusts the height of the clamping roller 31 through the elongated hole 41 to make it fit the outer circle surface of the skin, and adjusts the position and jet angle of the rotating air nozzle 53. The electrical control box 2 controls the heating tube inside the heating copper plate 17 to be powered on and heated. The temperature is collected and fed back in real time. When the temperature reaches the set value and stabilizes, the equipment enters the standby state. The operator fills the missing glue and exposed wire defects of the shell with the appropriate compounded rubber. Then the shell is placed on the arc-shaped top surface of the lower mold pad 9 and the position of the shell is adjusted so that the defect area is facing the working surface of the textured mold 3 to complete the position calibration. The electrical control box 2 sends a command to the drive motor 47, which rotates in the forward direction. Through the gear 45 and rack 44 transmission mechanism, it drives the two clamping frames 32 to move synchronously relative to each other, so that the two clamping rollers 31 are tightly attached to the outer circular surfaces of both sides of the skin, completing the rigid clamping and locking of the skin. The electrical control box 2 controls the piston rod of the telescopic cylinder 13 to extend, driving the heating component 7 and the textured mold 3 to move vertically downward until the arc-shaped working surface of the textured mold 3 is tightly pressed against the defect area of ​​the skin. The telescopic cylinder 13 maintains the set pressing pressure, and the pressure holding timer starts. At this time, the heat from the heating copper plate 17 is evenly transferred to the defect area through the textured mold 3, so that the filling rubber and the skin matrix rubber complete local vulcanization and fusion under the set temperature and pressure. Once the set pressure holding time is reached, the control box 2 automatically controls the piston rod of the telescopic cylinder 13 to retract, driving the textured mold 3 to move upward and reset; at the same time, the drive motor 47 rotates in the opposite direction, driving the two clamping frames 32 to move synchronously in opposite directions, releasing the clamping of the rubber skin. The control box 2 automatically opens the electric valve 55, and the rotating air nozzle 53 sprays high-pressure airflow to force-cool the processing area, allowing the rubber to cool and solidify quickly; after the air cooling time is reached, the electric valve 55 automatically closes, and the operator removes the rubber skin, checks the repair quality, and completes the processing of a single workpiece; When performing the transfer, the operator sets the transfer temperature and printing time through the electrical control box 2, replaces the textured mold 3 with the target transfer pattern, completes the equipment preheating, places the bag skin to be transferred on the lower mold pad 9, adjusts the position so that the target transfer area is facing the textured mold 3, places the heat transfer label on the transfer area of ​​the bag skin so that the printed side of the label faces the bag skin and the back side faces the textured mold 3. The auxiliary stabilizing mechanism 11 automatically clamps and positions the capsule skin. The telescopic cylinder 13 drives the textured mold 3 to descend and press, so that the textured mold 3, label, capsule skin, and lower mold pad 9 fit tightly together. The pressure holding timer starts, and heat is transferred to the transfer label through the textured mold 3, so that the ink layer of the label is thermally transferred to the surface of the capsule skin. After the pressing time is reached, the textured mold 3 moves upward to reset, the auxiliary stabilizing mechanism 11 releases the clamp, and the rotating air nozzle 53 performs air cooling and shaping on the transfer area. The operator removes the capsule skin to complete the transfer process.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
