Technical Field

[0001] The invention belongs to the technical field of profile spraying and curing equipment, and in particular relates to an automatic chain removal device and method after profile curing treatment. Background Art

[0002] In the current vertical powder or paint spraying process for aluminum profiles, the profiles with powder or paint sprayed on the surface will enter the curing furnace in a longitudinally suspended state, so that the sprayed material is cured at high temperature to form the required surface structure. There is a fan in the curing furnace, and the hot air circulation will cause the profile to shake, and then collisions may occur between the side-by-side profiles and between the profiles and the internal structure of the curing furnace, resulting in damage to the profile surface. Therefore, at present, before the profile enters the curing furnace, the lower ends of several suspended profiles are usually connected together by chains with clips to avoid the problem of excessive profile shaking; but at the same time, it is necessary to manually remove the chain on the profile after the curing process, resulting in low efficiency.

[0026] The present invention provides a device and method for automatically removing chains after curing of profiles, which solves the problem that the existing technical solution requires manual chain removal and is inefficient, and realizes automatic chain removal through a mechanical device, significantly improving efficiency, and can be applied to various profiles. For example, the background technology section of the Chinese invention patent with application publication number CN116493221A also mentions the above problem. Fig. 9 The drawings of the prior art patent are cited, but the chain structure is not limited thereto. For example, another common structure is to provide a small clip on the chain, and to clamp it at the lowest end of the profile.

[0027] See also Figure 1 , Figure 2 , an automatic chain removal device after curing of a profile according to an embodiment of the present invention comprises a lifting frame 1, which is arranged on one side of a profile hanging conveyor line; more specifically, the bottom of the lifting frame 1 is a base fixed to the ground; the lifting frame 1 is arranged vertically; the lifting frame 1 is arranged at the rear side of the profile hanging conveyor line (arranged close to the wall). The lifting frame 1 is connected to a lifting and moving frame 2 capable of lifting and moving through a lifting assembly, and a translational moving frame 3 capable of horizontal movement is connected to the lifting and moving frame 2 through a translation assembly, and a separation claw mechanism 4 capable of extending and retracting in the direction toward the profile hanging conveyor line is provided on the translational moving frame 3. Thus, the separation claw mechanism 4 can be lifted and lowered vertically and translated horizontally, and can achieve oblique movement by lifting and translating at the same time. The extension and retraction of the separation claw mechanism 4 should be understood in a broad sense, and the separation claw can be extended into the suspended profiles after being extended, and then pull off the chain with the downward movement; after the separation claw is retracted, it will not contact the profile and the chain, which is convenient for the movement and reset of the lifting and moving frame 2 and other mechanisms.

[0028] See also Figure 2 , Figure 3 , Figure 4 In a specific embodiment, the lifting assembly includes a lifting guide rail 11, and the lifting guide rail 11 is arranged on the lifting longitudinal frame 1; for example, the lifting guide rail 11 is arranged on the front side of the lifting longitudinal frame 1, and is arranged vertically with the lifting longitudinal frame 1, and is arranged within a sufficiently long height range. In order to ensure reliable lifting and structural stability, it is preferred that the lifting longitudinal frame 1 has two columns, each of which has a lifting guide rail 11, and a crossbeam or the like can be optionally provided between the two columns to enhance the structural strength; a drag chain is provided on one side of the lifting longitudinal frame 1. A lifting slider is slidably connected to the lifting guide rail 11, and the lifting slider is connected to the lifting movable frame 2. A lifting rack 12 is provided on the lifting longitudinal frame 1, for example, the lifting rack 12 is arranged on the right side of the left column (or the inner side of the lifting longitudinal frame 1). A lifting motor 21 is installed on the lifting movable frame 2, and a gear is provided at the output end of the lifting motor 21 and meshes with the lifting rack 12. Therefore, the gear at the output end of the lifting motor 21 can move on the lifting rack 12, thereby driving the lifting movable frame 2 and other structures thereon to move up and down along the lifting guide rail 11.

[0029] The translation assembly includes a translation guide rail 31, which is arranged on the translation moving frame 3, for example, the translation guide rail 31 is arranged below the horizontal frame plate of the translation moving frame 3, and the translation guide rail 31 is preferably two parallel ones to ensure the stability of movement. A translation slider is slidably connected to the translation guide rail 31, and the translation slider is connected to the lifting and moving frame 2; for example, the lifting and moving frame 2 is an inverted L-shaped plate structure, in which the vertical plate is slidably connected to the lifting longitudinal frame 1, and the upper horizontal plate is used to support and slide the translation moving frame 3 at the top. A translation rack 32 is provided on the translation moving frame 3, for example, it is arranged below the horizontal frame plate of the translation moving frame 3. A translation motor 22 is provided on the lifting and moving frame 2, and the output end of the translation motor 22 faces upward. The output end of the translation motor 22 is provided with a gear and meshes with the translation rack 32. Therefore, the gear at the output end of the translation motor 22 can push the translation rack 32 , and then drive the translation moving frame 3 and other structures thereon to move horizontally left and right along the translation guide rail 31 .

[0030] It can be understood that the above embodiment only provides a preferred solution, and the present invention is not limited thereto. For example, the lifting / moving mechanism can also be selected as a screw mechanism, a pulley mechanism, a telescopic cylinder mechanism, etc., and any method that can achieve controllable driving movement is available.

[0031] In a preferred embodiment, the separation claw mechanism 4 includes a separation claw mounting frame 41, on which a plurality of separation claws 42 are arranged at intervals. The position and / or length of the separation claws 42 are adjustable, so as to facilitate installation and adjustment, so that the spacing of the separation claws 42 is adapted to the spacing of the profiles suspended by the profile suspension conveyor line. Figure 4 As shown, the separation claw mounting frame 41 is in the shape of a flat plate with a strip hole formed thereon, and the separation claw 42 is connected to the strip hole of the separation claw mounting frame 41 by bolts, so that the installation position of the separation claw 42 can be adjusted in the strip hole. And / or, as Figure 5 As shown, the separation claw 42 is an adjustable and retractable structure, which includes a sleeve at the rear section and a claw head at the front section, the claw head is sleeved in the sleeve, and the claw head and the sleeve are connected by bolts, so that the total length of the separation claw 42 can be adjusted by adjusting the distance that the claw head extends out of the sleeve. The end (free end) of the separation claw 42 has a downward bend or notch, etc., to form a claw / hook structure to ensure that the chain can be hooked more stably.

[0032] See also Figure 3 , Figure 4 In one embodiment of the present invention, the extension and retraction of the separation claw are achieved by flipping. The separation claw mounting frame 41 is connected to a separation claw flip shaft 43, for example, the separation claw flip shaft 43 is fixed to the bottom of the plate-shaped separation claw mounting frame 41 through connecting plates at both ends. A flip shaft frame 33 is provided on the translation moving frame 3, and the flip shaft frame 33 is rotationally connected to the separation claw flip shaft 43; the flip shaft frame 33 is preferably, for example, a bearing frame, which is sleeve-connected to the separation claw flip shaft 43 through a bearing. The separation claw flip shaft 43 is connected to a flip drive motor 44, for example, the flip drive motor 44 is fixedly mounted on a mounting plate on the upper side of the translation moving frame 3. Thus, when the separation claw mechanism 4 is in the retracted state, the separation claw 42 and the separation claw mounting frame 41 are vertical and close to the lifting longitudinal frame 1; when the separation claw mechanism 4 is in the extended state, the flipping drive motor 44 drives the separation claw flipping axis 43 to have an angle different from that in the retracted state, for example, by 90°, so that the separation claw 42 and the separation claw mounting frame 41 are horizontal, and the separation claw 42 protrudes forward from the front side surfaces of the remaining components such as the translation moving frame 3 and the lifting moving frame 2.

[0033] Alternatively, see Figure 5 , Figure 6 In another embodiment of the present invention, the extension and retraction of the separation claw is achieved by telescoping. The separation claw mounting frame 41 is slidably connected to the translation moving frame 3 through a telescopic track assembly 34 (including a slide rail and a slider). The translation moving frame 3 is provided with a telescopic rotating shaft 45, and the telescopic rotating shaft 45 is connected to a telescopic driving motor 46, and the telescopic driving motor 46 is, for example, fixedly mounted on a mounting plate on the upper side of the translation moving frame 3. The telescopic rotating shaft 45 is transmission-connected to the separation claw mounting frame 41 to convert the rotation of the telescopic rotating shaft 45 into the translation of the separation claw mounting frame 41. For example Figure 6As shown, a pulley group is provided on the mounting plate on the upper side of the translational movable frame 3, wherein a driving pulley in the pulley group is coaxially fixed with the telescopic rotating shaft 45, and two driven pulleys in the pulley group are horizontally distributed laterally, and a transmission belt is connected to the pulley group for transmission, thereby forming a horizontal section of transmission belt parallel to the telescopic rail assembly 34 between the above-mentioned two driven pulleys, and one point of the transmission belt is fixed to the separation claw mounting frame 41, and as the telescopic rotating shaft 45 and the driving pulley rotate, the section of the transmission belt between the two driven pulleys will drive the separation claw mounting frame 41 to move horizontally back and forth.

[0034] It is understandable that the above embodiments only provide two preferred solutions, and the present invention is not limited thereto. For example, a screw mechanism, a gear rack mechanism, a telescopic cylinder mechanism, etc. may also be selected to realize the extension and retraction of the separation claw, and any method that can realize controllable driving movement is acceptable.

[0035] like Figure 2 , Figure 4 In the preferred embodiment shown, a limit anti-swing member 5 is provided on the translation moving frame 3. The limit anti-swing member 5 is used to limit the suspended profile. When the profile swings, the limit anti-swing member 5 can support and block the profile, limiting the swing amplitude of the profile to a smaller range, thereby preventing the profile from swinging too much and colliding with the mechanical structure. The position-limiting anti-swing member 5 is, for example, an inclined / curved plate / hood-shaped member located above the separation claw mechanism 4. The front end face of the position-limiting anti-swing member 5 is horizontally flush. When a row of profiles leans against the front end face of the position-limiting anti-swing member 5, the row of profiles are basically flush, and the profiles are close to a vertical state (the profiles are not in contact with the position-limiting anti-swing member 5 in a natural, ideal vertical state); the front end face of the position-limiting anti-swing member 5 slightly protrudes from the lifting and moving frame 2, the translational moving frame 3, etc., so that when the separation claw mechanism 4 is in the retracted state, the front end face of the position-limiting anti-swing member 5 that can contact the profile is the front end face; when the separation claw mechanism 4 is in the extended state, the separation claw 42 protrudes from the front end face of the position-limiting anti-swing member 5. Optionally, as Figure 5 As shown, the translation moving frame 3 also has a baffle plate on the front side, and an avoidance hole or avoidance groove for the separation claw 42 is opened on the baffle plate. The baffle plate can also be optionally configured to play the role of a limit anti-swing member 5.

[0036] like Figure 4 In the preferred embodiment shown, a gap detection mounting bracket 35 is provided on the translation moving frame 3, and a gap detection sensor (not shown in the figure) is provided on the gap detection mounting bracket 35. The gap detection sensor is used to ensure that the separation claw 42 is located in the gap position between the profiles when extended by detecting whether there is a profile in front. For example, a plurality of gap detection sensors are provided at the position corresponding to the separation claw 42 / corresponding to the gap position of the separation claw 42, or only one is provided as a reference based on the same spacing between the separation claws 42.

[0037] like Figure 1 In the preferred embodiment shown, a lifting position sensor 13 for directly or indirectly sensing the height position of the separation claw mechanism 4 is provided on the lifting longitudinal frame 1. For example, the lifting position sensor 13 is arranged on the side of the lifting longitudinal frame 1, and there are at least two of them arranged at the highest and lowest lifting positions. The object sensed by the lifting position sensor 13 is, for example, a detection plate protruding on the side, and the detection plate is, for example, arranged on the lifting and moving frame 2, thereby indirectly sensing the height position of the separation claw mechanism 4 and avoiding the loss of control of its lifting and moving range.

[0038] like Figure 3 In the preferred embodiment shown, a profile position sensor 23 for sensing the profile is provided on the lifting and moving frame 2. The profile position sensor 23 is located below the separation claw mechanism 4 and is used to detect whether there is a profile in front when the lifting and moving frame 2 moves up and down. When it is detected that there is no profile at the height position during the downward movement, it means that the lower end of the profile has been reached, thereby determining the approximate position of the lower end of the profile, that is, the approximate position of the chain.

[0039] It is conceivable that the above-mentioned sensors, such as infrared sensors, etc., and the setting mode and position of the sensors can be selected as needed. For example, as needed, the profile position sensor 23 and the gap detection sensor can exist at the same time; or in some embodiments, the profile position sensor 23 is also configured to be able to detect the profile gap to ensure that the separation claw 42 is located in the gap position between the profiles when it is extended, so that the gap detection mounting bracket 35 and the gap detection sensor are not required. In addition, in the case where no sensor is set, the corresponding function can be realized by direct input program control, but this may be lacking in intelligence and automation, such as being unable to adapt to profiles of different lengths, or each time it is necessary to move a sufficiently large height distance to ensure that profiles of various lengths can be applied, which will lead to an increase in the lifting and moving distance, reduced work efficiency, and increased energy consumption.

[0040] In some preferred embodiments, a chain conveyor belt (not shown in the figure) is provided directly below the profile hanging conveyor line, and the removed chain will fall onto the chain conveyor belt and can be automatically conveyed away, for example, transported back to the process of installing the chain before curing, further forming an overall automated processing solution.

[0041] In some preferred embodiments, Figure 1As shown, a front-end material length measuring mechanism 7 is provided on the upstream side of the lifting longitudinal frame 1. The function of the front-end material length measuring mechanism 7 is to measure the length of the profile before the profile is conveyed to the lifting longitudinal frame 1, thereby providing a reference for the chain removal work and helping to speed up the real-time design calculation control of the separation claw mechanism and other partial actions. The front-end material length measuring mechanism 7 can adopt any method that can achieve length measurement; preferably, the front-end material length measuring mechanism 7 adopts a grating ruler, which is vertically arranged and arranged on the front and rear sides of the profile suspension conveyor line.

[0042] like Figure 1 , Figure 2 As shown, a rear end chain hanging mechanism is provided on the downstream side of the lifting vertical frame 1. Figure 7 Preferably, the rear chain hanging mechanism includes a chain hanging longitudinal frame 6, on which a chain hanging plate 621 is provided, and the height position of the chain hanging plate 621 is adjustable. The chain hanging plate 621 has a nail plate portion 622, and the nail plate portion 622 has a plurality of chain hanging nails 623 protruding toward one side of the lifting longitudinal frame 1; for example, the chain hanging plate 621 may be provided with a plurality of holes and bolts installed thereon, thereby forming the nail plate portion 622. The nail plate portion 622 is located directly below the profile hanging conveyor line, so that in the case where the chain still has a clip connected to a profile, after the chain moves to the rear chain hanging mechanism, the chain link of the chain will be hung by the nail plate portion 622 of the chain hanging plate 621, and then as the profile continues to be conveyed, the chain will be pulled off the profile, thereby ensuring that the chain is completely removed.

[0043] The height position of the chain plate 621 can be adjusted, for example Figure 7 As shown, it includes an adjusting screw rod 624, an adjusting motor 625, and a limiting slide 626. The adjusting screw rod 624 and the limiting slide 626 are arranged vertically side by side. The adjusting screw rod 624 and the upper and lower ends of the chain hanging longitudinal frame 6 are rotatably arranged, for example, through a bearing frame. The back side of the chain hanging plate 621 is fixedly connected with a threaded sleeve, such as a nut, and is threadedly connected to the screw rod 624. The output end of the adjusting motor 625 is connected to the adjusting screw rod 624. The limiting slide 626 acts as a guide rail and is slidably connected to the back side of the chain hanging plate 621. Therefore, the chain hanging plate 621 is basically unable to rotate and can only be lifted and lowered under the threaded cooperation of the screw rod mechanism. In this way, the height position of the chain hanging plate 621 can be automatically adjusted by the motor to be suitable for profiles of different lengths, ensuring that the chain hanging plate 621 is located below the profile, and at the same time, it will not be too far away from the bottom of the profile to cause the chain to not be hung or the chain pulling effect is poor.

[0044] See also Figure 8 In another preferred embodiment of the present invention, Figure 7Different from the structure shown, the rear chain hanging mechanism includes a chain hanging vertical frame 6, a clamping mechanism 611 and a chain detection device 612. The clamping mechanism 611 is located below the profile hanging conveyor line, so that the lower end of the profile on the profile hanging conveyor line is located above the clamping mechanism 611. When there is still a chain on the individual profile that has not been completely detached after the above structure, the remaining part of the chain will be suspended and hung on the lower end of the individual profile. The drooping chain can enter the clamping mechanism 611, and then the chain can be clamped by the action of the clamping mechanism 611. The clamping mechanism 611 is connected to the chain hanging vertical frame 6 through the clamping lifting mechanism 613 and / or the clamping translation mechanism 614, so that it can be lifted and lowered and / or translated, and then the chain that has not been detached can be pulled off the profile. The chain detection device 612 is arranged adjacent to the clamping mechanism 611 and is located on one side (e.g., the rear side) of the profile hanging conveyor line. In other words, the chain detection device 612 is located near the clamping mechanism 611. The chain detection device 612 does not block the profile and the chain, and can also accurately detect whether the chain has entered or is about to enter the clamping mechanism 611. The chain detection device 612 is, for example, a laser radar or other photoelectric detection switch / sensor. The chain detection device 612 is connected to the control system of the rear end chain hanging mechanism or directly connected to the clamping mechanism 611 to transmit signals and realize the required action process.

[0045] More specifically, if Figure 8 As shown, the clamping mechanism 611 includes a horizontal clamping mechanism base plate, and the clamping mechanism base plate is provided with a slide rail slider assembly, which includes two sliders, and each slider is provided with a protruding clamping rod 615. The slide rail slider assembly also has a driving device, so as to drive the two clamping rods 615 to move toward each other (clamp the chain) and move away from each other (release the chain); based on the existing technology, the driving device of this function is easy to implement, for example, the slide rail slider assembly itself adopts the existing "linear guide bidirectional positive and negative tooth" type slide product with this function, or the two sliders are controlled by cylinders / electric cylinders respectively, etc., which will not be elaborated here.

[0046] It is worth noting that in the preferred embodiment of the present invention, the clamping rod 615 is conical, gradually tapering from the fixed end to the free end, and both clamping rods 615 are arranged to be tilted downward relative to the horizontal direction; with this structure, after the chain is released, the chain will easily fall down and separate from the clamping rod 615 under the action of gravity, and will not remain on the clamping mechanism 611 to affect subsequent work. In addition, the upper part of the clamping mechanism 611 has an inclined shielding plate, which can block the driving structure such as the slider of the clamping mechanism 611, and only expose the clamping rod 615 to prevent the chain from entering the driving structure of the clamping mechanism 611 and causing jamming.

[0047] The clamping lifting mechanism 613 is for example the same as the aforementioned Figure 7 The height position adjustable structure in the embodiment is similar, and the chain hanging longitudinal frame 6 is provided with a vertical adjustment screw 624 and a limit slide 626 arranged side by side, and the adjustment screw 624 and the upper and lower ends of the chain hanging longitudinal frame 6 are rotatably arranged, for example, through a bearing frame. A threaded sleeve, such as a nut, is fixedly connected to the back side of the clamping mechanism 611 (the clamping mechanism bottom plate), and is threadedly connected to the adjustment screw 624 in a matching manner; the driving part of the clamping lifting mechanism 613 is a motor (adjusting motor 625), and the output end of the adjustment motor 625 is connected to the screw 624. The limit slide 626 acts as a guide rail, and is slidably connected to the back side of the clamping mechanism 611 (the clamping mechanism bottom plate), so that the clamping mechanism 611 can move up and down under the drive of the motor of the clamping lifting mechanism 613.

[0048] The clamping translation mechanism 614 is, for example, a clamping translation cylinder. The clamping mechanism bottom plate of the clamping mechanism 611 is two layers stacked and slidingly matched with each other. The bottom plate of the bottom layer is directly connected to the clamping lifting mechanism 613 to achieve overall lifting. The clamping translation cylinder is fixedly installed on the bottom plate of the bottom layer. The piston rod of the clamping translation cylinder is connected to the bottom plate of the upper layer, thereby driving the clamping rod 615 to translate horizontally; through lateral translation or repeated shaking, the chain can also be separated from the profile. It is preferred to have both the clamping lifting mechanism 613 and the clamping translation mechanism 614. After the clamping rod 615 clamps the chain, it moves downward and shakes left and right at the same time, which makes the chain pulling more efficient, and shaking left and right after pulling off the chain can make the chain fall faster. It can be understood that the above-mentioned mechanical structure can be replaced with a variety of equivalents based on the prior art. The present invention is not limited to the above-mentioned specific structure. The focus is on being able to achieve the required action process and effect.

[0049] Based on the above scheme of the present invention, the present invention provides a method for automatically removing the chain after the profile is cured. The following only describes the preferred embodiment in which the profile position sensor 23 for sensing the profile is provided on the lifting and moving frame 2 to reflect the better effect of the present invention. It can be understood that the control can be realized by other means without the sensor, which has been explained in the previous text. It can be understood that the state of the device when in use is as follows. Figure 1 The front of the device shown is provided with Fig. 9 The profile suspension conveyor shown ( Fig. 9 The rear of the profile hanging conveyor line shown in the figure is the side wall of the curing furnace. After the profile is output from the curing furnace, the rear of the profile hanging conveyor line is the device), thus forming Fig.10 Status shown.

[0050] The preferred method comprises the following steps: Step S1, the initial state (for the convenience of description, the state just after completing a chain pulling action is called the initial state) is that the separation claw mechanism 4 is in a retracted state and the position is lower than the lower end of the profile on the profile hanging conveyor line; the translation moving frame 3 is translated to the upstream side of the profile hanging conveyor line (reset); Step S2, the lifting and moving frame 2 is lifted and moved up and down, and the lower end position of the profile on the profile hanging conveyor line is detected by the profile position sensor 23; Step S3, according to the detection result of the profile position sensor 23, the lifting and moving frame 2 rises and moves to above the lower end position of the profile on the profile hanging conveyor line, with a sufficient distance from the lower end of the profile, so that the separation claw mechanism 4 is located above the chain clamped at the lower end of the profile; and the separation claw 42 of the separation claw mechanism 4 is located at the gap position between the profiles (guaranteed by the profile position sensor 23 or the gap detection sensor); It should be noted that the actions in the above step S1 and steps S2 and S3 can be performed step by step or simultaneously, and they are described separately in this article only for the convenience of expression and understanding; Step S4, the separation claw mechanism 4 moves translationally toward the downstream side of the profile hanging conveyor line under the drive of the translation moving frame 3, and the moving speed is adapted to the speed of the profile moving on the profile hanging conveyor line, so that the separation claw mechanism 4 (the separation claw 42) and the profile (the gap position) move synchronously in the horizontal direction; this synchronous movement process is, for example, set to be consistent with the profile hanging conveyor line, or is monitored in real time by the profile position sensor 23 or the gap detection sensor; Step S5, the separation claw mechanism 4 is switched from the retracted state (e.g., gradually converted) to the extended state, and extends into the profile gap position; during this process, the translation movement described in step S4 continues; Step S6, the separation claw mechanism 4 moves downward under the drive of the lifting and moving frame 2; (optionally, during this process, the translational movement described in step S4 continues;) During this process, as the separation claw mechanism 4 moves downward relative to the profile, the separation claw mechanism 4 pulls the chain clamped at the lower end of the profile downward, so that the clamp gradually detaches from the profile, thereby separating the chain from the profile; It should be noted that the separation claw 42 in the above steps S5 to S6 moves downward while also moving synchronously with the profile to the downstream side (such as Figure 1 The separation claw 42 moves on the right side (in the figure), thereby ensuring that the separation claw 42 does not scratch the surface of the profile; in step S6 (i.e. when the separation claw mechanism 4 pulls the chain downward), it can also be selected to move asynchronously, but only move downward, or make a slow, short-distance reverse movement relative to the profile, so that the separation claw 42 is closer to the clip of the chain, which helps to remove the chain at one time and avoid residual clips on the profile; of course, this process will cause a small swing of the profile and surface friction, which will not affect the quality of the profile; Step S7, the separation claw mechanism 4 continues to move downward or up and down or to extend and retract to ensure that the chain is separated from the profile, and the chain is separated from the separation claw mechanism 4; In step S8, the separation claw mechanism 4 is switched from the extended state to the retracted state, and returns to the initial state described in step S1, and the cycle is repeated.

[0051] Further for those with Figure 8 The preferred embodiment of the rear end chain hanging mechanism shown also includes the following steps: (for the case where the separation claw mechanism 4 fails to remove all the clamps) when the chain detection device 612 detects that the chain has moved to the position of the clamping mechanism 611 (for example, between the two clamping rods 615), the clamping mechanism 611 clamps the chain, and then the clamping mechanism 611 moves downward and / or reciprocates horizontally to separate the chain from the profile, and then the clamping mechanism 611 releases the chain and resets the clamping mechanism 611.

[0052] In summary, this solution solves a problem that has long been desired to be solved in this field. Compared with the traditional manual operation method, this solution uses a mechanical device to realize the automatic removal of the chain clamped at the lower end of the profile without manual work during the transportation process, which significantly improves work efficiency and reduces the labor intensity of the staff; and in the process of removing the chain, it can ensure that the mechanical structure will not scratch the surface of the profile; compared with the existing patent CN116493221A, the patent designs a new type of curing device and process to avoid the process of adding chains, while this solution is designed from another perspective to replace manual removal of chains. It can be imagined that this solution can use the existing mature curing furnace and its process, so it can ensure that the curing treatment effect is consistent with the existing process and relatively stable. A set of devices of this solution can be added after the existing curing furnace, which is easier to use.
