Description

Technical Field

[0001] This invention relates to the field of automotive parts processing, and more specifically to an auxiliary device for wrapping an outer layer of heat-insulating aluminum foil around automotive air conditioning system piping components. Background Technology

[0002] After the automotive air conditioning system pipes are manufactured, they need to be wrapped with heat-insulating aluminum foil. The existing heat-insulating aluminum foil has insulation cotton on the inside and aluminum foil on the outside. When using it, workers need to cut the required length of heat-insulating aluminum foil with a blade, then cut open a part of the insulation cotton with the blade, and then remove the insulation cotton. This allows the sticky inner wall of the aluminum foil to stick together with the heat-insulating aluminum foil, so that the heat-insulating aluminum foil is wrapped around the outside of the pipe.

[0003] Because some equipment lacks the corresponding functions, most of the above steps need to be performed by workers. If the blade is not used to cut the insulation cotton, it is easy to damage the aluminum foil and cut fingers. Although some customized equipment has the above functions, the fixed-length cutting of the heat insulation aluminum foil and the cutting of the insulation cotton require multiple actuators, resulting in a more complex equipment structure and higher cost. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary device for wrapping an outer layer of heat-insulating aluminum foil around pipe components in an automotive air conditioning system, so as to solve the problems mentioned in the background art.

[0005] An auxiliary device for winding outer heat-insulating aluminum foil around pipe components in an automotive air conditioning system includes a base, an unwinding device, a cutting assembly, a pulling device, and a triggering device. The unwinding device is located on the left side of the base and is used to mount the rolled heat-insulating aluminum foil. The cutting assembly includes a cutting blade and a slit blade, and the cutting blade is used to cut the heat-insulating aluminum foil.

[0006] The pulling device includes a clamping plate and a translation frame. The clamping plate is located inside the translation frame and can move in the vertical direction. The translation frame can slide within the base.

[0007] When the translation frame moves to the cutting blade, the triggering device reduces the distance between the clamping plate and the bottom of the translation frame to clamp the heat insulation aluminum foil. When the translation frame moves away from the cutting blade, it stretches the heat insulation aluminum foil, causing the cutting blade to cut the insulation cotton of the heat insulation aluminum foil.

[0008] The triggering device can also increase the distance between the clamping plate and the bottom of the translation frame when the translation frame reaches the extreme position far away from the cutting blade, thereby releasing the heat-insulating aluminum foil and realizing the feeding of the heat-insulating aluminum foil.

[0009] Preferably, the unwinding device includes a support and a limiting roller. An unwinding wheel is rotatably connected to the support. The limiting roller is located between the unwinding wheel and the cutting blade and is rotatably connected to the base. The heat-insulating aluminum foil is sleeved on the unwinding wheel, and its protruding part is laid on the base and passes through the upper surface between the limiting roller and the base.

[0010] Preferably, the cutting assembly further includes a frame, a fixing block, and a connecting block. The cutting blade is fixedly connected to the fixing block, the fixing block is fixedly connected to the base, and a gap is left between the cutting blade and the edge of the heat-insulating aluminum foil. A linear module is provided on the frame, the cutting blade is fixedly connected to the connecting block, the connecting block is fixedly connected to the slide of the linear module, and the moving direction of the linear module is perpendicular to the translation direction of the translation frame.

[0011] Preferably, the pulling device further includes a motor, which is fixedly connected to the base, and its output shaft is fixedly connected to a lead screw. The lead screw is rotatably connected to the base. A guide rod is provided on each side of the lead screw. The translation frame is slidably connected to the guide rod and threadedly connected to the lead screw. Two slide rods are fixedly connected to the top of the clamping plate. The slide rods pass through the top of the translation frame and are slidably connected to the translation frame. A stop block is fixedly connected to the top of the slide rod. A spring is sleeved on the slide rod between the translation frame and the clamping plate. A pulley is fixedly and rotatably connected to one end of the clamping plate.

[0012] Preferably, the triggering device includes a functional block and a lifting block. The functional block is located on the same side as the pulley. A ramp bar is rotatably connected to the functional block. The ramp bar is inclined with the left end higher than the right end, and a horizontal section is connected to the left side of its top end. The horizontal section is located on the functional block. The lifting block is located at the right end of the base and on the same side as the roller. The lifting block has an inclined surface that is lower on the left and higher on the right.

[0013] Preferably, two support rods are fixedly connected to the base, the functional block is slidably connected to the support rods, an anti-detachment block is fixedly connected to the end of the support rod, and a spring is sleeved on the support rod between the anti-detachment block and the functional block.

[0014] The advantages of this invention are:

[0015] By setting up a pulling device and a triggering device to work together, the clamping plate can automatically clamp the heat insulation aluminum foil in the appropriate position and pull it out to the required length with the translation frame. During the process of pulling out the aluminum foil, the insulation cotton can also be cut open with a cutting knife, which makes it easier to wrap the pipe with the heat insulation aluminum foil later.

[0016] In addition, the lifting block can also cause the clamping block to loosen the heat insulation aluminum foil for easy unloading. Compared with the existing equipment, the fixed-length cutting and the actuator for cutting the insulation cotton are omitted, making the overall structure of the equipment simple, without complicated control programs, easy to maintain later, and meeting the low-cost requirements.

[0026] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 5 As shown, an auxiliary device for winding outer heat-insulating aluminum foil for automotive air conditioning system piping components includes a base 1, an unwinding device 2, a cutting assembly 3, a pulling device 4, and a triggering device 5. The unwinding device 2 is located on the left side of the base 1 and is used to install the rolled heat-insulating aluminum foil. The cutting assembly 3 includes a cutting blade 31 and a slit blade 32. The cutting blade 31 is used to cut the heat-insulating aluminum foil.

[0028] The pulling device 4 includes a clamping plate 41 and a translation frame 42. The clamping plate 41 is disposed inside the translation frame 42 and can move along the vertical direction. The translation frame 42 can slide inside the base 1.

[0029] When the translation frame 42 moves to the cutting blade 31, the triggering device 5 reduces the distance between the clamping plate 41 and the bottom of the translation frame 42 to clamp the heat insulation aluminum foil. When the translation frame 42 moves away from the cutting blade 31, it stretches the heat insulation aluminum foil, so that the cutting blade 32 cuts the heat insulation cotton of the heat insulation aluminum foil.

[0030] The triggering device 5 can also increase the gap between the clamping plate 41 and the bottom of the translation frame 42 when the translation frame 42 reaches the extreme position away from the cutting blade 31, thereby releasing the heat insulation aluminum foil and realizing the feeding of the heat insulation aluminum foil.

[0031] In this embodiment, the unwinding device 2 includes a support 21 and a limiting roller 22. An unwinding wheel 23 is rotatably connected to the support 21. The limiting roller 22 is located between the unwinding wheel 23 and the cutting blade 32, and is rotatably connected to the base 1. The heat-insulating aluminum foil is sleeved on the unwinding wheel 23, with its protruding portion laid on the base 1, and passes through the upper surface between the limiting roller 22 and the base 1. The limiting roller 22 vertically limits the heat-insulating aluminum foil.

[0032] In this embodiment, the cutting assembly 3 further includes a frame 33, a fixing block 34, and a connecting block 35. The cutting blade 32 is fixedly connected to the fixing block 34, and the fixing block 34 is fixedly connected to the base 1. A gap is left between the cutting blade 32 and the edge of the heat-insulating aluminum foil. A linear module 36 is provided on the frame 33. The cutting blade 31 is fixedly connected to the connecting block 35, and the connecting block 35 is fixedly connected to the slide of the linear module 36. The moving direction of the linear module 36 is perpendicular to the translation direction of the translation frame 42.

[0033] In this embodiment, the pulling device 4 further includes a motor 43, which is fixedly connected to the base 1, and its output shaft is fixedly connected to a lead screw 44. The lead screw 44 is rotatably connected to the base 1. A guide rod 45 is provided on each side of the lead screw 44. The translation frame 42 is slidably connected to the guide rod 45 and threadedly connected to the lead screw 44. Two sliding rods 46 are fixedly connected to the top of the clamping plate 41. The sliding rods 46 pass through the top of the translation frame 42 and are slidably connected to the translation frame 42. A stop block 47 is fixedly connected to the top of the sliding rod 46. A spring 48 is sleeved on the sliding rod 46 between the translation frame 42 and the clamping plate 41. A pulley 49 is fixedly and rotatably connected to one end of the clamping plate 41.

[0034] In this embodiment, the triggering device 5 includes a functional block 51 and a lifting block 52. The functional block 51 is located on the same side as the pulley 49. A ramp 53 is rotatably connected to the functional block 51. The ramp 53 can rotate downwards and reset under the action of gravity, and then rest on the functional block 51 again. The ramp 53 is inclined with the left end higher than the right end, and a horizontal section 54 is connected to the left side of its top end. The horizontal section 54 is located on the functional block 51. The lifting block 52 is located on the right end of the base 1 and on the same side as the roller. The lifting block 52 has a slope that is lower on the left and higher on the right.

[0035] In this embodiment, two support rods 55 are fixedly connected to the base 1. The functional block 51 is slidably connected to the support rods 55. An anti-detachment block 56 is fixedly connected to the end of the support rod 55. A spring 57 is sleeved on the support rod 55 between the anti-detachment block 56 and the functional block 51. When the connecting block 35 contacts the functional block 51, it can move against the functional block 51 towards the anti-detachment block 56. The spring 57 is compressed, ensuring that the cutting blade 31 can move to the other side of the heat-insulating aluminum foil, thereby completely cutting the heat-insulating aluminum foil and preventing the functional block 51 from interfering with the movement of the cutting blade 31.

[0036] Working process and its principle:

[0037] When using this device, the rolled-up heat-insulating aluminum foil is first placed on the unwinding roller 23. Then, a section of the heat-insulating aluminum foil is pulled out and passed under the limiting roller 22, extending a distance to the right. The limiting roller 22 then vertically limits its movement. At this point, the insulation cotton of the heat-insulating aluminum foil is on top, and the aluminum foil is on the bottom.

[0038] When the roller has not reached the functional block 51, the clamping plate 41 is in the lowest holding position. At this time, the clamping plate 41 is closest to the bottom of the translation frame 42. The motor 43 is started and the lead screw 44 rotates to drive the translation block to move towards the heat insulation aluminum foil. When the roller contacts the ramp 53, it can move upward along the ramp 53, thereby causing the clamping plate 41 to rise and the spring 48 to be compressed.

[0039] When the roller moves to the horizontal section 54, the clamping plate 41 is at its highest point. At this time, the bottom of the translation plate extends below the heat-insulating aluminum foil, and the heat-insulating aluminum foil is located below the clamping plate 41. When the roller continues to move to the left, it will fall from the left end of the horizontal section 54. The spring 48 is released, causing the clamping plate 41 to press the heat-insulating aluminum foil tightly onto the translation frame 42, thereby fixing the heat-insulating aluminum foil.

[0040] Then the motor 43 reverses, causing the translation frame 42 to move to the right. When the translation frame 42 moves to the right, the roller moves to the right as well. When the roller comes into contact with the ramp 53, it will push the ramp 53 upward. The ramp 53 is forced to rotate upward and open, avoiding the roller. The roller can move freely to the right without being blocked by the ramp 53. When the roller leaves the ramp 53 from below, the ramp 53 can rotate downward and reset under the action of gravity, and rest on the functional block 51 again.

[0041] The distance the translation frame 42 moves is determined by the required length of the heat-insulating aluminum foil. During the movement of the translation frame 42, the heat-insulating aluminum foil will be stretched, allowing the cutting blade 32 to cut through the insulation cotton. The cutting blade 32 is not in contact with the aluminum foil. When the translation frame 42 moves to the required position, the linear module 36 is activated, driving the connecting block 35 to move towards the functional block 51. The cutting blade 31 moves along with it, cutting the heat-insulating aluminum foil. When the connecting block 35 contacts the functional block 51, it can move against the functional block 51 towards the anti-detachment block 56. The second spring 57 is compressed, ensuring that the cutting blade 31 can move to the other side of the heat-insulating aluminum foil, achieving a complete cut of the heat-insulating aluminum foil and preventing the functional block 51 from interfering with the movement of the cutting blade 31.

[0042] After the heat insulation aluminum foil is cut, the cutting blade 31 resets, and the translation frame 42 continues to move towards the lifting block 52. The inclined surface of the lifting block 52 lifts the roller, causing the clamping block to release the heat insulation aluminum foil. At this time, the required length of heat insulation aluminum foil can be removed from the equipment.

[0043] like Figure 5 As shown, the upper layer is insulation cotton, and the lower layer is aluminum foil. The side of the aluminum foil that contacts the insulation cotton is adhesive. When using the pre-cut insulation aluminum foil, tear off the cut insulation cotton to expose the adhesive side of the aluminum foil. Then wrap the insulation cotton around the outside of the pipe, and then use the adhesive side of the aluminum foil instead of tape to stick and seal the insulation aluminum foil.

[0044] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
