Description

Technical Field

[0001] The present invention relates to the technical field of profile surface coating, and particularly to a profile coating machine. Background Art

[0002] Polyurethane pultruded composite materials are composed of high-hardness polyurethane resin and glass fiber. During the manufacturing process, continuous reinforcing fibers first pass through a preforming device, then are impregnated in polyurethane resin, and finally are cured and formed through a heating die. This process ensures the tight combination of polyurethane resin and reinforcing fibers, forming a composite material with high strength and good corrosion resistance. This material has the characteristics of high strength, high toughness, and light weight, and is widely used in the fields of construction, infrastructure, transportation, and electronics and electrical appliances.

[0003] Polyurethane pultruded composite materials are used to assemble the frames of photovoltaic modules. Since the frames of photovoltaic modules are exposed to the air, the polyurethane pultruded composite materials themselves have the problem of insufficient weather resistance. Especially during long-term outdoor exposure, the resin layer on their surfaces is prone to powdering, discoloration, and even fiber exposure. Therefore, polyurethane pultruded composite materials usually need to be coated.

[0004] US5492583A discloses an on-line coating method and device for pultruded composite materials. This method adds a coating die for on-line coating of pultruded profiles downstream of the pultrusion die, that is, the composite material directly enters the coating die for coating after being output from the pultrusion die. Although this method can directly complete the coating of the composite material, since the profile is pulled by a traction device after passing through the coating die, the coating speed is equal to the pultrusion speed. The maximum pultrusion speed of polyurethane pultruded composite materials is 1.5 meters per minute. It can be seen from this that the maximum coating speed of polyurethane pultruded composite materials can only be 1.5 meters per minute. According to the research of the applicant, the coating speed of polyurethane pultruded composite materials can completely be greater than the pultrusion speed. Therefore, the method of directly configuring a coating die downstream of the pultrusion production line to coat polyurethane pultruded composite materials actually reduces the coating efficiency. Summary of the Invention

[0005] The present invention provides a profile coating machine, which can improve the coating efficiency of profiles.

[0006] The profile coating machine includes: a frame;

[0007] A coating die installed on the frame, and the coating die has a through hole matching the profile;

[0008] A coating liquid feeding mechanism for inputting the coating liquid into the coating die. The coating liquid feeding mechanism is installed on the frame, and the coating liquid feeding mechanism is connected to the coating die. It further includes:

[0009] A first feeding component located upstream of the coating die, and the first feeding component is connected to the frame;

[0010] A second feeding component located upstream of the coating die, and the second feeding component is connected to the frame. After the second feeding component cooperates with the first feeding component, a channel for the profile to pass through is formed between the second feeding component and the first feeding component. The first feeding component and / or the second feeding component generate power for the profile, so that the profile moves along the channel towards the coating die;

[0011] A guiding component for guiding the tail of the coated profile from a high position to a low position. The guiding component is located downstream of the coating die, and the guiding component is connected to the frame.

[0012] In the present invention, after the profile enters the channel, the profile is clamped and fed through the action of the first feeding component and the second feeding component, so that the profile moves quickly towards the coating die. During this process, each guide wheel in the first feeding component and the second feeding component guides the profile to prevent the profile from deviating. When the profile passes through the coating die, the coating liquid is coated on the surface of the profile. After the coated profile is output from the coating die, its tail cooperates with the guiding component, and under the guidance of the guiding component, the tail of the profile moves from a high position to a low position and finally reaches the required position.

[0013] Compared with the coating in the background art, in the present invention, the pultruded profiles are cut according to the required length, for example, the length of each profile is 2.5 meters, and then fed into the coating machine for coating. Since the coating machine has a relatively fast coating speed for the profiles, currently the coating speed is 30 meters per minute. Therefore, after the present invention separates the coating line from the pultrusion line, compared with the fastest coating speed of 1.5 meters per minute in the background art, the feeding efficiency of the present invention is significantly improved.

[0033] Frame J, channel T, profile G, inner baffle G1, slot G2. Specific implementation mode

[0034] As Figures 1 to 13 As shown, the profile coating machine of the present invention includes a frame J, a coating die A, a coating liquid feeding mechanism B, a first feeding component C, a second feeding component D, and a guiding component E. A channel T for the profile G to pass through is formed between the second feeding component D and the first feeding component C. The following will separately elaborate on each part and the relationship between them in detail.

[0035] The coating die A is installed on the frame J. The coating die A has a through hole matching the profile G, and the shape of the through hole is adapted to the cross-section of the profile X. The coating die A includes a die body 1, a first mounting seat 2, and a first adjusting mechanism for adjusting the position of the first mounting seat 2 to make the die body 1 correspond to the channel. The through hole on the coating die A is located on the die body 1. The structure of the die body 1 is prior art. The die body 1 is connected to the first mounting seat 2, and the first mounting seat 2 is fixed to the first adjusting mechanism.

[0036] Driven by the first adjusting mechanism, the first mounting seat 2 can move along the up-and-down direction Y and the front-and-back direction Z of the frame J, and the die body 1 follows the first mounting seat 2 to move along the up-and-down direction Y and the front-and-back direction Z of the frame J, so that the through hole on the die body 1 corresponds to the channel T. The direction in which the profile G moves along the channel T is the transverse direction X of machining.

[0037] The first adjusting mechanism includes a second mounting seat 3, a first slide rail 4, a first slide block 5, a first connecting seat 6, a first linear actuator 7, a third mounting seat 8, a second slide rail 9, a second slide block 10, a second connecting seat 11, and a second linear actuator 12. The first slide rail 4 is fixed on the second mounting seat 3. The first slide block 5 is slidably matched with the first slide rail 4. The first connecting seat 6 is fixed to the second mounting seat 3. The first linear actuator 7 is connected to the first connecting seat 6 and is matched with the first slide block 5. A protruding portion 5a is provided on the side surface of the first slide block 5, and the first linear actuator 7 is matched with the protruding portion 5a. The first slide block 5 can be made to move along the front-and-back direction Z of the frame J by the first linear actuator 7.

[0038] The first linear driver 7 can adopt linear drive components such as air cylinders and hydraulic cylinders. The first linear driver 7 can also adopt a micrometer. Since the adjustment of the correspondence between the through hole on the die body 1 and the channel T belongs to fine adjustment, in this embodiment, the first linear driver 7 preferably adopts a micrometer, and the micrometer has the advantage of convenience during fine adjustment.

[0039] The third mounting seat 8 is fixed on the first sliding seat 5. The second slide rail 9 is fixed to the third mounting seat 8. The second sliding seat 10 is slidably engaged with the second slide rail 9. The second connecting seat 11 is fixed to the second sliding seat 10. The second linear driver 12 is connected to the second connecting seat 11 and cooperates with the third mounting seat 8. The second linear driver 12 can adopt linear drive components such as air cylinders and hydraulic cylinders. The second linear driver 12 can also adopt a micrometer. Since the adjustment of the correspondence between the through hole on the die body 1 and the channel T belongs to fine adjustment, in this embodiment, the second linear driver 12 preferably adopts a micrometer, and the micrometer has the advantage of convenience during fine adjustment.

[0040] The first adjustment mechanism further includes a first stroke limit block 13 and a first locking screw 14. The first stroke limit block 13 is fixed to the second mounting seat 3. The first stroke limit block 13 is provided with a first strip-shaped hole 13a. The first sliding seat 5 is provided with a first screw hole. The first locking screw 14 passes through the first strip-shaped hole 13a and is threadedly connected to the first screw hole. The first locking screw 14 has a clearance fit with the first strip-shaped hole 13a.

[0041] When the first sliding seat 5 moves along the front-back direction Z of the frame J to the required position through the first linear driver 7, the first linear driver 7 stops working. Rotate the first locking screw 14, and the first locking screw 14 presses the first stroke limit block 13 against the first sliding seat 5, thereby preventing the first sliding seat 5 from moving under non-adjustment operations (such as the vibration force generated during equipment operation). When adjustment is required, loosen the first locking screw 14.

[0042] The first adjustment mechanism further includes a second stroke limit block 15 and a second locking screw 16. The second stroke limit block 15 is fixed to the third mounting seat 8. The second stroke limit block 15 is provided with a second strip-shaped hole 15a. The second sliding seat 10 is provided with a second screw hole. The second locking screw 16 passes through the second strip-shaped hole 15a and is threadedly connected to the second screw hole. The second locking screw 16 has a clearance fit with the second strip-shaped hole 15a.

[0043] When the third mounting seat 8 is moved along the up and down direction Y of the frame J to the required position by the second linear driver 12, the second linear driver 12 stops working, and the second locking screw 16 is rotated. The second locking screw 16 presses the second stroke limiting block 15 against the second sliding seat 10, thereby preventing the second sliding seat 10 from moving under non-adjustment operations (such as the vibration force generated during equipment operation). When adjustment is required, the second locking screw 16 is loosened.

[0044] The first adjustment mechanism further includes a first tension spring 17, a first connecting member 18, and a second connecting member 19. The first connecting member 18 is fixed to the second mounting seat 3, the second connecting member 19 is fixed to the first sliding seat 5. One end of the first tension spring 17 is connected to the first connecting member 18, and the other end of the first tension spring 17 is connected to the second connecting member 19. The first connecting member 18 and the second connecting member 19 can be screws or rivets. After the first sliding seat 5 is slidably engaged with the first slide rail 4, there is a first spaced space between the first sliding seat 5 and the second mounting seat 3, and the first tension spring 17, the first connecting member 18, and the second connecting member 19 are located in the first spaced space.

[0045] The first adjustment mechanism further includes a second tension spring 20, a third connecting member 21, and a fourth connecting member 22. The third connecting member 21 is fixed to the third mounting seat 8, the fourth connecting member 22 is fixed to the second sliding seat 10. One end of the second tension spring 20 is connected to the third connecting member 21, and the other end of the second tension spring 20 is connected to the fourth connecting member 22. The third connecting member 21 and the fourth connecting member 22 can be screws or rivets. The second sliding seat 10 is slidably engaged with the second slide rail 9, and there is a second spaced space between the second sliding seat 10 and the third mounting seat 8, and the second tension spring 20, the third connecting member 21, and the fourth connecting member 22 are located in the second spaced space.

[0046] In this embodiment, since both the first linear driver 7 and the second linear driver 12 use a micrometer, the first linear driver 7 abuts against the convex portion 5a, and the second linear driver 12 abuts against the third mounting seat 8. Therefore, the first sliding seat 5 is always kept in abutment with the first linear driver 7 by the action of the first tension spring 17, and the gravity of the second sliding seat 10 can be borne by the action of the second tension spring 20.

[0047] The coating liquid feeding mechanism B for inputting the coating liquid into the coating die A is installed on the frame J. The coating liquid feeding mechanism B is connected to the coating die A. The frame J is composed of a workbench and a bracket located on the workbench. The coating die A, the first feeding assembly C, the second feeding assembly D, and the guiding assembly E are respectively connected to the workbench, and the coating liquid feeding mechanism B is connected to the bracket. The coating liquid feeding mechanism B is located above the coating die A. The structure of the coating liquid feeding mechanism B is prior art and will not be described in detail here.

[0048] The first feeding component C is located upstream of the painting die A, and the first feeding component C is connected to the frame J; the first feeding component C includes a first support 23, a first driving mechanism, a first driving roller 24, a first guiding mechanism, and a second guiding mechanism. The first support 23 is fixed to the frame J, the first driving mechanism is connected to the first support 23, and the first driving roller 24 transmits the power generated by the first driving mechanism to the profile G. The first driving roller 24 is fixed to the first driving mechanism. When the first driving mechanism works, it drives the first driving roller 24 to rotate. Since the surface of the first driving roller 24 is in contact with the lower surface of the profile G, the first driving roller 24 feeds the profile G towards the die body 1 through the frictional force between it and the lower surface of the profile G.

[0049] The first driving mechanism includes a first motor 25, a first transmission shaft 26, a first transmission mechanism 27, and a second transmission shaft 28. The first motor 25 preferably uses an electric motor, and the electric motor can use a servo motor, etc. The first motor 25 is connected to one end of the first transmission shaft 26. The first transmission shaft 26 and the second transmission shaft 28 are respectively pivotally connected to the first support 23. A bearing assembly is fixed on the first support 23, and the first transmission shaft 26 and the second transmission shaft 28 are respectively connected to the bearing assembly on the first support 23. When the first transmission shaft 26 and the second transmission shaft 28 are subjected to torsion, they can rotate relative to the first support 23. The other end of the first transmission shaft 26 is connected to the first transmission mechanism 27, and the first transmission mechanism 27 is connected to the second transmission shaft 28. The first transmission mechanism 27 can use a belt transmission mechanism, a sprocket chain transmission mechanism, or a gear transmission mechanism. In this embodiment, the first transmission mechanism 27 preferably uses a belt transmission mechanism. The first driving roller 24 is fixed on both the first transmission shaft 26 and the second transmission shaft 28.

[0050] The first guiding mechanism guides the profile G to prevent the profile G from running off when feeding towards the die body 1. The first guiding mechanism is arranged both upstream and / or downstream of the first driving roller 24. The first guiding mechanism includes a second support 29, a first guide wheel 30, and a second guide wheel 31. The second support 29 is fixed to the frame J. The first guide wheel 30 guides the rear surface of the profile G. The first guide wheel 30 is pivotally connected to the second support 29 and is installed on the upper side surface of the second support 29. The second guide wheel 31 guides the lower surface of the profile G. The second guide wheel 31 is pivotally connected to the second support 29 and is installed on the front side surface of the second support 29. The included angle formed by the axes of the second guide wheel 31 and the first guide wheel 30 is 90°.

[0051] The second support 29 is provided with a first guiding groove 32 that cooperates with the profile G and a second guiding groove 33 that communicates with the first guiding groove 32. The first guiding groove 32 is located upstream of the second guiding groove 33. The width of the input end of the first guiding groove 32 is greater than the width of the output end of the first guiding groove 32. The width of the second guiding groove 33 is equal to the width of the output end of the first guiding groove 32.

[0052] In this embodiment, the material of the profile G is fiber-reinforced composite material (FRP) or aluminum alloy. The profile G is used for the frame of the photovoltaic module. Therefore, this kind of photovoltaic module frame has an inner baffle G1. Since the inner baffle G1 cooperates with the first guiding groove 32 and the second guiding groove 33, setting the width of the input end of the first guiding groove 32 to be greater than the width of the output end of the first guiding groove 32 is beneficial for the inner baffle G1 to enter the first guiding groove 32.

[0053] The second guiding mechanism guides the profile G to prevent the profile G from running off when feeding towards the mold body 1. The second guiding mechanism cooperates with the first guiding mechanism. The second guiding mechanism includes a third support 34, a cross beam 35, a guiding component 36, a fourth support 37, a third guide wheel 38, and a first linear driving mechanism 39. The guiding component 36 is slidably matched with the cross beam 35. The guiding component 36 is fixed to the third support 34. The fourth support 37 is fixed to the cross beam 35. The third guide wheel 38 guides the front surface of the profile G. The third guide wheel 38 is pivotally connected to the fourth support 37. An interval space for the profile G to pass through is formed between the third guide wheel 38 and the first guiding mechanism. The first linear driving mechanism 39 is used to drive the cross beam 35 to move to adjust the interval space between the third guide wheel 38 and the profile G. The first linear driving mechanism 39 is connected to the cross beam 35. The first linear driving mechanism 39 can adopt a cylinder, a hydraulic cylinder or an electric lead screw.

[0054] A notch 35a is provided at the bottom of the cross beam 35. The first driving mechanism passes through the notch 35a, and the first transmission shaft 26 passes through the notch 35a, thereby avoiding interference between the first transmission shaft 26 and the notch 35a.

[0055] The first feeding component C further includes an inlet guiding component C1, which is located upstream of the first guiding mechanism and the second guiding mechanism. The inlet guiding component includes a fifth support 40, a first shaft 41, a second shaft 42, a third shaft 43, a fourth shaft 44, a first bearing 45 for guiding the lower surface of the profile G, a second bearing 46 for guiding the rear surface of the profile G, a third bearing 47 for guiding the front surface of the profile G, and a fourth bearing 48 for guiding the upper surface of the profile G. There are two fifth supports 40 arranged at intervals. The two ends of the first shaft 41 are respectively connected to a fifth support 40. One end of the second shaft 42 is fixed to one of the fifth supports 40. One end of the third shaft 43 is fixed to the other fifth support 40. One end of the fourth shaft 44 is fixed to the other end of the second shaft 42, and the other end of the fourth shaft 44 is fixed to the other end of the third shaft 43. The first bearing 45 is connected to the first shaft 41, the second bearing 46 is connected to the second shaft 42, the third bearing 47 is connected to the third shaft 43, and the fourth bearing 48 is connected to the fourth shaft 44.

[0056] The profile G is input into the first feeding component C through a feeding device (not shown in the figure). The profile G output from the feeding device moves along a straight line. When the profile G passes through the inlet guiding component C1, the first bearing 45, the second bearing 46, the third bearing 47, and the fourth bearing 48 respectively cooperate with the surface of the profile G, forming support for the profile on the one hand and guiding the profile on the other hand, preventing the profile G from deviating and enabling the profile G to smoothly enter the channel T between the first feeding component C and the second feeding component D.

[0057] The second feeding component D is located upstream of the painting die A. The second feeding component D is connected to the frame J. After the second feeding component D cooperates with the first feeding component C, a channel T for the profile G to pass through is formed between the second feeding component D and the first feeding component C. The first feeding component C and / or the second feeding component D generate power for the profile G, causing the profile G to move along the channel towards the painting die A. In this embodiment, both the first feeding component C and the second feeding component D generate power for the profile G.

[0058] The second feeding component D includes a frame 49, a lifting drive 50, a second driving mechanism, a second driving roller 51, and a third guiding mechanism. The frame 49 is located above the first feeding component C. The lifting drive 50 drives the frame 49 to lift. The lifting drive 50 is connected to the frame 49. The lifting drive 50 drives the frame 49 to lift. The lifting drive 50 is composed of a support frame and a linear drive component. The support frame is fixed to the frame J, and the linear drive component is fixed to the support frame. The linear drive component passes through the support frame and is connected to the frame 49.

[0059] The second driving mechanism is connected to the frame 49. The second driving roller 51 transmits the power generated by the second driving mechanism to the profile G, and the second driving roller 51 is fixed to the second driving mechanism. The second driving mechanism includes a second motor 52, a third transmission shaft 53, a second transmission mechanism 54, and a fourth transmission shaft 55. The second motor 52 is connected to the third transmission shaft 53. The second motor 52 preferably adopts an electric motor, and the second motor 52 is preferably connected to the third transmission shaft 53 through a sprocket chain mechanism. The third transmission shaft 53 and the fourth transmission shaft 55 are respectively pivotally connected to the frame 49. A bearing assembly is installed on the frame 49, and the third transmission shaft 53 and the fourth transmission shaft 55 are respectively connected to the bearing assembly in the frame 49. The third transmission shaft 53 is connected to the second transmission mechanism 54, and the second transmission mechanism 54 is connected to the fourth transmission shaft 55. The second transmission mechanism 54 preferably adopts a sprocket chain mechanism. The second driving rollers 51 are fixed on both the third transmission shaft 53 and the fourth transmission shaft 54. The second driving roller 51 cooperates with the upper surface of the profile G, and the power generated when the second driving mechanism works is transmitted to the profile G through the second driving roller 51.

[0060] The third guiding mechanism guides the upper surface of the profile G. The third guiding mechanism is arranged both upstream and / or downstream of the second driving roller 51, and the third guiding mechanism is connected to the frame 49. The third guiding mechanism includes a sixth support 56 and a fourth guide wheel 57 for guiding the upper surface of the profile G. The sixth support 56 is L-shaped. One end of the sixth support 56 is fixed to the frame 49, and the other end of the sixth support 56 extends downward below the frame 49. The fourth guide wheel 57 is pivotally connected to the other end of the sixth support 56.

[0061] The second feeding assembly D further includes a guide rod assembly 58 fixed to the frame J. The guide rod assembly 58 passes through the frame 49, and the guide rod assembly 58 is slidably matched with the frame 49. When the frame 49 moves up and down, it is guided by the guide rod assembly 58 to prevent the frame 49 from running off track.

[0062] After the profile G is coated, it is necessary to release the profile G to a position lower than the height of the first feeding assembly C. Therefore, in the present invention, the tail of the coated profile G is guided from a high position to a low position through the guiding assembly E. The guiding assembly E is located downstream of the coating die A, and the guiding assembly E is connected to the frame J. The guiding assembly E includes a base 59, and the base 59 is provided with an inclined surface 60 for guiding the tail of the profile G from a high position to a low position. The profile G has a slot G2 for inserting a solar panel. During use, the slot G2 cooperates with the inclined surface 60 on the base 59.

[0063] The guiding component E further includes a horizontal adjuster 61, a height adjuster 62, a connecting plate 63, a third motor 64, and a transition wheel 65. The height adjuster 62 is connected to the output end of the horizontal adjuster 61. Both the horizontal adjuster 61 and the height adjuster 62 adopt linear drive components. In this embodiment, the horizontal adjuster 61 and the height adjuster 62 preferably adopt electric linear modules. One end of the connecting plate 63 is fixed to the output end of the height adjuster 62, and the other end of the connecting plate 63 is fixed to the third motor 64. The transition wheel 65 is fixed to the torque output end of the third motor 64. The highest part of the transition wheel 65 is higher than the highest part of the inclined surface 60, and the width of the transition wheel 65 is smaller than the width of the inclined surface 60. For example, the width of the transition wheel 65 is one-fourth of the width of the inclined surface 60.

[0064] Through the actions of the horizontal adjuster 61 and the height adjuster 62, the transition wheel 65 is adjusted to a position matching the slot G2 on the profile G, so that the transition wheel 65 supports the coated profile G.

[0065] Theoretically, the slot G2 does not require coating liquid, but during the coating process, the wall surface of the slot G2 also obtains the coating. When the profile G is output from the mold body 1, if there is no support from the transition wheel 65 in the middle, only the highest part of the inclined surface 60 can contact the slot G2. Since there is a coating on the wall surface of the slot G2, during the movement of the profile G along the highest part of the inclined surface 60, the friction between the inclined surface and the wall surface of the slot G2 is static friction, which will scrape the coating on the wall surface of the slot G2, resulting in the destruction and falling off of a large amount of the coating on the wall surface of the slot G2. In this embodiment, after the transition wheel 65 is arranged upstream of the base 59, when the profile G is first supported by the transition wheel, at this time, the inclined surface 60 does not support the profile G. Since the width of the transition wheel 65 is smaller than the width of the inclined surface 60, and the third motor 64 drives the transition wheel 65 to rotate, the friction between the transition wheel 65 and the wall surface of the slot G2 is rolling friction. Therefore, by contacting the wall surface of the slot G2 with the transition wheel 65, the damage to the coating can be greatly reduced. As the profile G continues to move, when the profile G detaches (the tail detaches) from the filter wheel 65, the tail slot G2 on the profile G falls on the inclined surface 60. During the process of assembling the profile G into the frame of the photovoltaic module, a 45-degree bevel needs to be cut at both the head and the tail of the profile G. Therefore, even if the coating in the tail slot G2 is damaged, since this part is cut off during use, it will not be affected.

[0066] It further includes a detection component for judging whether the coating on the profile G is qualified. The detection component is located between the first feeding component C and the guiding component E. The detection component includes: a high-speed camera 66 for collecting the surface image of the coated profile G, and a comparator 67 electrically connected to the high-speed camera 66. There are multiple high-speed cameras 66. In this embodiment, 4 high-speed cameras are provided to collect the images of the front surface, rear surface, upper surface and lower surface of the profile respectively. The high-speed camera 66 transmits the collected images to the comparator 67, and the comparator 67 compares the collected images with the standard images stored in the comparator 67 to judge whether the coating on the surface of the profile G is qualified. The comparator 67 can adopt an industrial control computer, which is prior art and will not be elaborated here.
