Description

Technical Field

[0001] The invention relates to the technical field of profile surface coating, and in particular to an ejection feeding device for profile coating. Background Art

[0002] Polyurethane pultrusion composite materials are composed of high-hardness polyurethane resin and glass fiber. During the manufacturing process, the continuous reinforcing fibers first pass through a preforming device, then are impregnated with polyurethane resin, and finally are cured and formed by heating the mold. This process ensures that the polyurethane resin and the reinforcing fibers are tightly combined to form 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 construction, infrastructure, transportation, electronics and electrical appliances and other fields.

[0003] Polyurethane pultrusion composite materials are used to assemble into photovoltaic module frames. Since photovoltaic module frames are exposed to the air, polyurethane pultrusion composite materials themselves have insufficient weather resistance. Especially in long-term outdoor exposure, the resin layer on the surface is prone to powdering, discoloration, and even fiber exposure. Therefore, polyurethane pultrusion composite materials usually need to be coated.

[0004] US5492583A discloses a method and device for online coating of pultruded composite materials, in which a coating die for online coating of pultruded profiles is added downstream of the pultrusion die, that is, the composite material is directly fed into the coating die for coating after being output from the pultrusion die. Although this method allows the composite material to be coated directly, since the profile is towed by a traction device after passing through the coating die, the coating speed is equal to the pultrusion speed. The maximum pultrusion speed of the polyurethane pultrusion composite material is 1.5 m / min. Therefore, it can be seen that the maximum coating speed of the polyurethane pultrusion composite material can only be 1.5 m / min. According to the applicant's research, the coating speed of the polyurethane pultrusion composite material can be completely greater than the pultrusion speed. Therefore, the method of directly configuring a coating die downstream of the pultrusion production line to coat the polyurethane pultrusion composite material actually reduces the coating efficiency. Summary of the invention

[0005] The invention provides an ejection feeding device for coating a profile, and the invention can improve the feeding efficiency during coating of the profile.

[0006] Ejection feeding device for profile coating, including:

[0007] A number of bearing components for cooperating with the profiles;

[0008] A flexible transmission mechanism, wherein the plurality of bearing components are evenly arranged on the flexible transmission mechanism, the bearing components are connected to the flexible transmission mechanism, and the flexible transmission mechanism drives the bearing components to move;

[0009] The ejection drive mechanism is used to cooperate with the flexible transmission mechanism. Each time the flexible transmission mechanism works, it drives all the load-bearing components to move. When any load-bearing component matches the power output end of the ejection drive mechanism, the flexible transmission mechanism stops working, and the ejection drive mechanism drives the profile matched on the load-bearing component to move.

[0010] In the present invention, the structure of the bearing component and the flexible transmission mechanism is similar to a magazine in a firearm, the profile is similar to a bullet in a firearm, and the ejection drive mechanism is similar to a firing device in a firearm. When any bearing component matches the power output end of the ejection drive mechanism, the flexible transmission mechanism stops working, and the profile is fired by the force output by the ejection drive mechanism, so that the profile moves toward the coating machine. Then, the ejection drive mechanism is reset, and the flexible transmission mechanism resumes working, driving the next bearing component carrying the profile to match the power output end of the ejection drive mechanism, and repeats this process, thereby orderly conveying each profile to the coating machine.

[0011] Compared with the coating of the background technology, the present invention cuts the pultruded profile into required lengths and assembles it into the bearing components of the ejection feeding device, and finally the profile is ejected to the coating machine by the ejection feeding device. Since the coating speed of the coating machine on the profile is relatively fast, the current coating speed is 30 meters per minute, and the feeding speed of the ejection feeding device matches the speed of the coating machine, therefore, the feeding speed is also 30 meters per minute. After the coating line and the pultrusion line are separated, the present invention significantly improves the feeding efficiency compared to the fastest feeding and coating speed of 1.5 meters per minute in the background technology.

DETAILED DESCRIPTION

[0025] like Figures 1 to 11 As shown, the ejection feeding device for profile coating of the present invention includes a bearing component 1, a flexible transmission mechanism, and an ejection driving mechanism. The various parts and the relationship between them are described in detail below.

[0026] The bearing component 1 is used to cooperate with the profile X. The material of the profile X is a polyurethane pultruded composite material. The profile X is used to be assembled into a photovoltaic module frame. The number of bearing components 1 is several, and the number of bearing components 1 is, for example, 25. The bearing component 1 is used to support the profile X. The bearing component 1 includes a support bar 1a and a first stop bar 1b. The support bar 1a supports the profile X, and the support bar 1a is connected to the flexible transmission mechanism. The cross-section of the first stop bar 1b is L-shaped. After the first stop bar 1b is fixed to the support bar 1a, a guide groove 1c for cooperating with the profile X is formed between the first stop bar 1b and the support bar 1a.

[0027] In the present invention, the material of the profile X is a fiber reinforced composite material (FRP) or an aluminum alloy, and the profile X is used for a photovoltaic module frame. Therefore, the photovoltaic module frame has an inner baffle X1, and the inner baffle X1 is clearance-matched with the guide groove 1c. Since the downstream of the entire ejection feeding device is a coating machine for coating the profile X, when the profile X moves on the bearing component 1 after being subjected to force, the profile X is guided by the clearance-matching effect of the inner baffle X1 and the guide groove 1c, thereby preventing the profile X from deviating, and allowing the profile X to accurately enter the input end of the coating machine.

[0028] The bearing component 1 further includes a second stopper bar 1d, one end of which is fixed to the support bar 1a, and the other end of which is located above the support bar 1a (from Figure 2 In the present invention, one end of the first baffle bar 1b is located above the support bar 1a, so a receiving groove 1f is formed between the support bar 1a and the first baffle bar 1b and the second baffle bar 1d, and the profile X cooperates with the receiving groove 1f.

[0029] The bearing component 1 also includes a fastener (not shown in the figure), and the support bar 1a is provided with a first mounting hole 1e. The fastener cooperates with the first mounting hole 1e and the flexible transmission mechanism to fix the support bar 1a and the flexible transmission mechanism. The first mounting hole 1e is a stepped hole, and the first mounting hole 1e passes through the support bar 1a. The fastener preferably uses a screw, and the screw passes through the first mounting hole 1e and is threadedly connected with the flexible transmission mechanism, so that the bearing component 1 and the flexible transmission mechanism are fixed as a whole.

[0030] The plurality of bearing components 1 are evenly arranged on the flexible transmission mechanism, and the bearing components 1 are connected to the flexible transmission mechanism, and the flexible transmission mechanism drives the bearing components 1 to move. The flexible transmission mechanism includes a first frame 2, a first motor 3, a first driving shaft 4, a first driving wheel 5, a first driven shaft 6, a first driven wheel 7, and a first flexible component 8. The first driving shaft 4 is rotatably arranged on the first frame 2; the first driving wheel 5 is fixed on the first driving shaft 4; the first driven shaft 6 is rotatably arranged on the first frame 2; the first driven wheel 7 is fixed on the first driven shaft 7; the first flexible component 8 is flexibly matched with the first driving wheel 5 and the first driven wheel 7, the bearing component 1 is fixedly connected to the first flexible component 8, and the bearing component 1 moves with the first flexible component 8.

[0031] The first motor 3 can be an electric motor or a hydraulic motor. In the present invention, the first motor 3 preferably uses a servo motor, which has the characteristic of high precision. The first driving wheel 5 and the first driven wheel 7 can be sprockets or pulleys, and the first flexible component 8 can be a chain or a belt. In the present invention, the first driving wheel 5 and the first driven wheel 7 preferably use sprockets, and the first flexible component 8 preferably uses a chain.

[0032] The flexible transmission mechanism also includes a support plate 9 and a connecting nut 10. The support plate 9 supports the load-bearing component 1. One end of the support plate 9 is fixed to the first flexible component 8, and the other end of the support plate 9 is located on the outside of the first flexible component 8. Since the first flexible component 8 adopts a chain, the support plate 9 and the chain plate in the chain are integrally formed. There is an angle between the support plate 9 and the chain plate, and the angle is preferably 90°.

[0033] The support plate 9 is provided with a through hole 9a, and the connecting nut 10 is fixed to the support plate 9. The connecting nut 10 is preferably fixed to the support plate 9 by welding, and the screw hole on the connecting nut 10 matches the through hole 9a. In the present invention, the screw (fastener) in the bearing component 1 passes through the first mounting hole 1e and the through hole 9a and is threadedly connected with the connecting nut 10, so that the bearing component 1 and the flexible transmission mechanism are fixed as a whole.

[0034] The flexible transmission mechanism further includes a lining strip 11, which is fixed to the first frame 2 and is provided with a first guide groove 12 for guiding the first flexible component 8. The first flexible component 8 is a chain, and the chain plate in the chain is clearance-matched with the first guide groove 12. This structure can prevent the chain from running off during movement, thereby ensuring the accuracy of the chain movement.

[0035] The flexible transmission mechanism is used to cooperate with the ejection drive mechanism. Each time the flexible transmission mechanism works, it drives all the bearing components 1 to move. When any bearing component 1 matches the power output end of the ejection drive mechanism, the flexible transmission mechanism stops working, and the ejection drive mechanism drives the profile X matched on the bearing component 1 to move, so that the profile X on the bearing component 1 moves toward the downstream coating machine. Then, after the ejection drive mechanism is reset, the flexible transmission mechanism resumes working and drives the next bearing component 1 carrying the profile X to match the power output end of the ejection drive mechanism. This is repeated, so that each profile X is delivered to the coating machine in an orderly manner.

[0036] The ejection drive mechanism includes a first linear drive 13 and a firing assembly. The first linear drive 13 can be a linear drive component such as a cylinder, a hydraulic cylinder, an electric linear module, etc. In the present invention, the first linear drive 13 preferably uses an electric linear module, which has the advantage of high precision. The first linear drive 13 is used to generate firing power, and the firing assembly transmits the firing power to the profile X. The firing assembly is fixed to the power output end of the first linear drive 13.

[0037] In the present invention, the structure of the bearing component 1 and the flexible transmission mechanism is similar to a magazine in a firearm, the profile X is similar to a bullet in a firearm, and the ejection drive mechanism is similar to a firing device in a firearm. Therefore, the firing assembly is driven to move by the first linear drive 13, and the firing assembly applies the firing force to the profile X, so that the profile X moves toward the coating machine.

[0038] The firing assembly includes a first connecting plate 14, a second connecting plate 15, and a hammer assembly. The first connecting plate 14 is fixed to the power output end of the first linear drive 13, the second connecting plate 15 is fixed to the first connecting plate 14, an angle is formed between the second connecting plate 15 and the first connecting plate 14, and the hammer assembly is movably connected or fixedly connected to the first connecting plate 14.

[0039] In the present invention, the first linear drive 13 is located above the bearing component 1. Therefore, the power output by the first linear drive 13 needs to be transmitted to the profile X through the firing assembly. Therefore, it is connected to the second connecting plate 15 through the first connecting plate 14, and a 90° angle is formed between the second connecting plate 15 and the first connecting plate 14. After the hammer assembly is connected to the second connecting plate 15, the position of the hammer assembly matches the profile X. When the profile X needs to be fired, the hammer assembly can accurately fire at the profile X.

[0040] The hammer assembly includes a first connecting member 16, a hammer 17, and a spring 18. A through hole is provided on the second connecting plate 15. The first connecting member 16 passes through the through hole on the second connecting plate 15 and is gap-matched with the through hole. The hammer 17 is fixed to one end of the first connecting member 16. The hammer 17 and the first connecting member 16 can be connected by threads or fixed by welding. The other end of the first connecting member 16 is provided with a radial protrusion 19. The diameter of the radial protrusion 19 is larger than the aperture of the through hole on the second connecting plate 15. The spring 18 is sleeved on the first connecting member 16. One end of the spring 18 abuts against the second connecting plate 15, and the other end of the spring 18 abuts against the hammer 17.

[0041] When the hammer 17 transmits power to the profile X, the profile X generates a reaction force on the hammer 17, and the hammer 17 drives the first connecting member 16 to move in the opposite direction. During this process, the hammer 17 transmits the reaction force to the spring 18, and the spring 18 is compressed. Therefore, during the process of the hammer assembly firing the profile X, the hammer assembly has a buffering effect on the profile X, thereby preventing the end of the profile X from being deformed or broken due to excessive firing force.

[0042] The present invention also includes a calibration mechanism for calibrating the length of the profile X, the calibration mechanism includes a second frame 19, a first blocking component 20, a second blocking component 21, and a driving mechanism, the second frame 19 is composed of a first frame 19a and a second frame 19b, the first frame 19a is arranged along the height direction of the flexible transmission mechanism, the second frame 19b is arranged along the lateral direction of the flexible transmission mechanism, the two ends of the second frame 19b are respectively fixed to one first frame 19a, and the second frame 19a is located above the flexible transmission mechanism.

[0043] A guiding mechanism is installed on the second frame 19, and the guiding mechanism includes a guide rail 19c and a slide 19d. The guide rail 19c is fixed to the second frame 19a, and the slide 19d is slidably matched with the guide rail 19c. The slide 19d is fixed to the ejection drive mechanism. In the present invention, the slide 19d is preferably fixed to the first linear drive 13.

[0044] The first blocking member 20 is fixed to the second frame 19, and the first blocking member 20 is fixedly connected to the first frame 19a, and at least a part of the flexible transmission mechanism is located between the first blocking member 20 and the second blocking member 21. The driving mechanism drives the second blocking member 21 to move to adjust the distance between the second blocking member 21 and the first blocking member 20, and the driving mechanism is fixed to the second blocking member 21, and the distance between the first blocking member 20 and the second blocking member 21 is greater than or equal to the length of the profile X. The difference between the distance between the first blocking member 20 and the second blocking member 21 and the length of the profile X is less than 10 mm. In the present invention, the difference between the distance between the first blocking member 20 and the second blocking member 21 and the length of the profile X is 5 mm.

[0045] The driving mechanism includes a second linear driver 22, a third connecting plate 23, and a first connecting rod 24. The second linear driver 22 can use a linear driving component such as a cylinder, a hydraulic cylinder, and an electric linear module. In the present invention, the second linear driver 22 preferably uses an electric linear module, which has the advantage of high precision. The power output end of the second linear driver 22 is fixed to the third connecting plate 23, the third connecting plate 23 is fixed to the first connecting rod 24, and the third connecting plate 23 is also fixed to the ejection driving mechanism. In the present invention, the third connecting plate 23 is preferably fixed to the first linear driver 13 in the ejection driving mechanism, and the first connecting rod 24 is fixed to the second blocking component 21.

[0046] When the second linear drive 22 outputs power to drive the third connecting plate 23 to move, the third connecting plate 23 drives the first connecting rod 24 to move, so that the second blocking component 21 moves following the first connecting rod 24, thereby adjusting the distance between the second blocking component 21 and the first blocking component 20. When the third connecting plate 23 moves, it also drives the ejection drive mechanism to move, thereby making the distance between the power output end of the ejection drive mechanism and the end of the profile X constant.

[0047] For example, if the length of the profiles to be coated in the current batch is 2500 mm, the spacing between the first blocking component 20 and the second blocking component 21 is adjusted to 2505 mm through the calibration mechanism. When the profile X with a length greater than 2505 mm enters the interval space between the first blocking component 20 and the second blocking component 21, it will interfere with the first blocking component 20 and / or the second blocking component 21, so that the profile X with a length greater than 2505 mm cannot be placed in the bearing component 1. Therefore, only the profile with a length less than 2505 mm will not be hindered when entering the space between the first blocking component 20 and the second blocking component 21. It can be seen that the main function of the calibration mechanism is to prevent the profile X of unnecessary length from being placed in the bearing component 1.

[0048] The driving mechanism further includes a first slider 25 and a first slide rail 26. The first slider 25 and the first slide rail 26 are slidably matched. The first slide rail 26 is fixed to the second frame 19. The first slide rail 26 is a linear slide rail. When the second linear driver 22 outputs power to sequentially drive the third connecting plate 23 and the first connecting rod 24 to move, the first slider 25 and the first slide rail 26 cause the first connecting rod 24 to move linearly.

[0049] The second blocking member 21 is used to cooperate with one end of each profile X, and the calibration mechanism also includes a first detection component for detecting the other end of the profile X; the first detection component includes a photoelectric sensor 27. The first detection component also includes a third driver 28 for adjusting the position of the photoelectric sensor 27, the third driver 28 is fixed to the second frame 19, and the photoelectric sensor 27 is connected to the power output end of the third driver 28.

[0050] The spacing between the first blocking component 20 and the second blocking component 21 is set, and the profile X is assembled on the bearing component 1. When any bearing component 1 matches the power output end of the ejection drive mechanism:

[0051] If the first detection component detects the other end of the profile X matched with the bearing component 1, the length of the profile X meets the set distance between the first blocking component 20 and the second blocking component 21. If the first detection component fails to detect the other end of the profile X matched with the bearing component 1, the length of the profile X does not meet the set distance between the first blocking component 20 and the second blocking component 21.

[0052] Since the spacing between the first blocking component 20 and the second blocking component 21 determines that the profile X larger than the spacing cannot enter, there is another possibility: the profile X with a length much smaller than the spacing between the first blocking component 20 and the second blocking component 21 can enter, but the profile X with such a length is not required for current production, therefore, it is necessary to screen out the profile X with a length much smaller than the set spacing between the first blocking component 20 and the second blocking component 21. Therefore, in the present invention, one end of each profile X is matched with the second blocking component 21, and one end of each profile X is preferentially contacted with the second blocking component 21, and the other end of the profile X is detected by the first detection component. If the other end of the profile X is detected, it means that the length of the profile X meets the set spacing between the current first blocking component 20 and the second blocking component 21, and the profile X is the profile required for current production. If the first detection component does not detect the other end of the profile X, it means that the length of the profile X is much smaller than the set distance between the first blocking component 20 and the second blocking component 21. For example, if the length of the profile X is 2400 mm, the profile X is not the profile required for the current production. At this time, the ejection drive mechanism is stopped, that is, the ejection drive mechanism will not fire the profile X whose length is much smaller than the set value.

[0053] Since the profile X is relatively long, when the profile X is fed from the bearing component 1 to the coating machine under the firing action of the ejection drive mechanism, there is a spacing space of at least 500 mm between the bearing component 1 and the coating machine. Therefore, in order to prevent the profile X from deforming due to lack of support during the above-mentioned feeding process, the present invention also includes a support assembly for supporting the profile X driven by the ejection drive mechanism to be output from the bearing component 1. The support assembly includes a first support 29, a first connecting component 30, and a first rotating component 31 for supporting the profile X. The first connecting component 30 is connected to the first support 29 and the first rotating component 31, respectively. In the present invention, the first connecting component 30 is preferably a bolt, and the first rotating component 31 is preferably a bearing.

[0054] Since the length of the profile X is relatively long, the profile X may also swing when it is fed from the bearing component 1 to the coating machine under the firing action of the ejection drive mechanism. Therefore, in order to limit the swing amplitude of the profile X, the present invention also includes a limiting component for limiting the swing amplitude of the profile X during the movement. The limiting component is located on the upper side of the supporting component, and there is a spacing space between the supporting component and the limiting component for the profile X to pass through. The limiting component includes a second support 32, a second connecting component 33, and a second rotating component 34. The second connecting component 33 is respectively connected to the second support 32 and the second rotating component 34. In the present invention, the second connecting component 33 preferably adopts a bolt, and the second rotating component 33 preferably adopts a bearing.

[0055] The working process of the present invention is as follows:

[0056] S1, according to the length of the profile X to be coated in the current batch, the second linear drive 22 is started, and the second linear drive 22 drives the second blocking component 21 to move to adjust the distance between the second blocking component 21 and the first blocking component 20.

[0057] S2 , the operator manually places the profile X on the bearing component 1 , and makes the inner baffle X1 of the profile X match with the guide groove 1 c on the bearing component 1 .

[0058] S3, start the flexible transmission mechanism, the flexible transmission mechanism drives the bearing component 1 loaded with the profile X to move, when any bearing component 1 matches the power output end of the ejection drive mechanism, the flexible transmission mechanism stops working, and detects the other end of the profile X through the first detection component.

[0059] S4, if the first detection component detects the other end of the profile X, it means that the length of the profile X meets the set distance between the current first blocking component 20 and the second blocking component 21, and the profile X is the profile required for the current production. The ejection drive mechanism drives the profile X matched on the bearing component 1 to move, so that the profile X is fed to the coating machine.

[0060] If the first detection component does not detect the other end of the profile X, it means that the length of the profile X is much smaller than the set distance between the first blocking component 20 and the second blocking component 21, and the profile X is not the profile required for the current production. At this time, the ejection drive mechanism is stopped, that is, the ejection drive mechanism will not fire the profile X whose length is much smaller than the set value. The on-site staff will check the profile X, replace the non-compliant profile with a profile that meets the requirements, and then restart the feeding device.

[0061] In the above process, after the profile X on the current supporting component 1 matched with the ejection drive mechanism is output by the ejection drive mechanism, the ejection drive mechanism is reset, and the flexible transmission mechanism resumes working, driving the next supporting component 1 carrying the profile X to match with the power output end of the ejection drive mechanism, and repeating this process, so that each profile X is delivered to the coating machine in an orderly manner.
