Description

Technical Field

[0001] This invention relates to the field of venetian blind manufacturing technology, specifically to a device and method for manufacturing wooden venetian blind blades. Background Technology

[0002] Venetian blinds are installed on windows and are generally used for indoor and outdoor sun shading and ventilation. Unlike the soft texture of curtains, Venetian blind slats are typically made of injection-molded plastic or stamped aluminum alloy. Venetian blinds can withstand sunlight, wind, rain, and dust, and are easy to clean. Modern young people prefer wood-look Venetian blind slats to enhance the aesthetics and natural feel of their homes when decorating.

[0003] Currently, most venetian blind blades on the market have connecting holes at both ends and the middle. The larger connecting holes at the ends are used to connect the drive rope to drive the venetian blind blades to open and close, while the smaller connecting holes in the middle are used to connect the support rope to further support and connect the venetian blind blades. Traditional wooden venetian blind blades are mainly processed by cutting the wood multiple times with cutting equipment, and then feeding the wood into a drilling mechanism for drilling. This production method is not only low in output and efficiency, but also requires a lot of labor costs.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0005] The main objective of this invention is to provide a manufacturing equipment and method for wooden louver blades, which can effectively solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the solution of the present invention is:

[0007] A wooden louver blade manufacturing device includes a press, an upper mold, and a lower mold. The press includes a hydraulic cylinder and a base. The upper mold is connected to the power output end of the hydraulic cylinder. The lower mold is mounted on the upper surface of the base. The upper surface of the lower mold has a plurality of forming cavities. The lower end of the upper mold has a first mold core assembly and a second mold core assembly extending into the forming cavities. The first mold core assembly includes a first core body and a first driving mechanism. The first core body is rotatably connected to the upper mold. The first driving mechanism is located inside the upper mold and drives the first core body to rotate.

[0008] Furthermore, the first driving mechanism includes a gear rack, gears, rollers, a first driving block, and a second driving block. The upper mold includes a connecting template and an installation template. The upper end of the connecting template is connected to a hydraulic cylinder, and the lower end of the connecting template is connected to the installation template. The upper end of the first core is rotatably connected to the installation template via a bearing. The gear is sleeved on the upper end of the first core. The gear rack is slidably connected within the installation template. Both ends of the gear rack extend out of the installation template. The rollers are rotatably connected to both ends of the gear rack. The first driving block and the second driving block are mounted on a press. The first driving block and the second driving block are respectively located on both sides of the gear rack. The first driving block has a first abutting surface, and the second driving block has a second abutting surface. The rollers at both ends of the gear rack abut against the first abutting surface and the second abutting surface, respectively.

[0009] Furthermore, the upper surface of the mounting template is provided with a mounting groove, the mounting groove is provided with a guide groove and a first mounting hole, the first core is installed in the first mounting hole, the lower end of the toothed rack is slidably connected in the guide groove, and the side wall of the mounting template is provided with a through hole for the end of the toothed rack to extend out.

[0010] Furthermore, the first and second abutment surfaces are arc-shaped wavy surfaces.

[0011] Furthermore, it also includes a feeding device, which includes a feeder, a transverse drive device, and a longitudinal drive device. The transverse drive device includes a first connecting plate, a second connecting plate, a first motor, a first lead screw, and a first guide rail. The feeder is mounted on the first connecting plate, the first motor and the first guide rail are mounted on the second connecting plate, the lower end of the first connecting plate is slidably connected to the first guide rail, the first lead screw is connected to the power output end of the first motor, and the lower end of the first connecting plate is threadedly connected to the first lead screw through a first threaded block.

[0012] Furthermore, the longitudinal driving device includes a third connecting plate, a second motor, a second lead screw, and a second guide rail. The second motor and the second guide rail are mounted on the third connecting plate. The extension direction of the second guide rail is perpendicular to the extension direction of the first guide rail. The lower end of the second connecting plate is slidably connected to the second guide rail. The second lead screw is mounted on the power output end of the second motor. The second lead screw is threadedly connected to the lower end of the second connecting plate through a second threaded hole.

[0013] Furthermore, it also includes a discharge device, which includes a discharge frame, a discharge plate, a first conveyor belt, and a second conveyor belt. The discharge frame is connected to the base, and the discharge plate is slidably connected to the discharge frame. The discharge frame is equipped with a cylinder for driving the discharge plate to move horizontally. The discharge end of the discharge frame is connected to the feed end of the first conveyor belt, and the discharge end of the first conveyor belt is connected to the feed end of the second conveyor belt.

[0014] A method for manufacturing the above-mentioned equipment includes the following steps:

[0015] S1. The press drives the upper die to rise, causing the upper die and lower die to separate from each other;

[0016] S2. The longitudinal drive device drives the feeder to enter the upper part of the lower mold. The feeder transports materials such as wood chips and adhesives into the molding cavity. Then, the transverse drive device works with the longitudinal drive device to drive the conveyor to move laterally repeatedly along the front and back direction of the molding cavity, so that the material can be evenly filled into the molding cavity. When each molding cavity is filled with material, the longitudinal drive device drives the feeder away from the press.

[0017] S3. The press drives the upper mold to descend, so that the upper mold and the lower mold fit together. During the process of the upper mold gradually descending, the rollers at both ends of the toothed row slide and translate repeatedly through the abutment drive of the first abutment surface and the second abutment surface, thereby driving the first core to rotate repeatedly in the forward and reverse directions. This facilitates the discharge of the material in the forming cavity during the descent of the first core, allowing the first core to extend more smoothly into the material. Afterward, the upper mold and the lower mold close to hot press the material in the forming cavity into a window leaf.

[0018] S4. The press is left to stand for 2 minutes to allow the window leaf in the molding cavity to cool and solidify. Then the press drives the upper mold to rise, separating the upper mold from the lower mold. Since the connecting hole of the window leaf fits tightly with the first core and the second mold core assembly, the window leaf rises together with the upper mold during the process of the upper mold rising to demold.

[0019] S5. When the upper mold rises above the ejector plate, the ejector plate moves to below the upper mold via a cylinder. As the upper mold continues to rise, the rollers at both ends of the toothed rack slide and translate repeatedly via the abutment drive of the first and second abutment surfaces, driving the first core to rotate repeatedly in both directions. This causes sliding friction between the first core and the window leaf connecting hole. Through this friction, the sidewall of the window leaf connecting hole and the sidewall of the first core can slide and separate from each other, preventing the sidewall of the connecting hole from continuing to adhere to the sidewall of the first core. At this point, the window leaf loses its upward driving force and falls downward onto the ejector plate. The ejector plate then moves toward the first conveyor belt, which transports the window leaf to the second conveyor belt, where it is then collected.

[0020] S6. Workers transport the collected window slats to the spraying device for spraying and coloring. After the glue and pigments have dried, they are stored in the warehouse for preservation.

[0021] Compared with existing technologies, the advantages of this invention are that it can form multiple window slats at once, effectively improving the production efficiency of louvered window slats. Simultaneously, during the rising and falling of the upper mold, the first driving mechanism can drive the first core to continuously rotate and flip, allowing the first core to smoothly extend into the material of the forming cavity, facilitating the formation of the connecting holes. During demolding, the sidewalls of the connecting holes can be separated from the sidewalls of the first core, preventing the sidewalls of the connecting holes from adhering to the sidewalls of the first core, thus aiding in rapid demolding of the window slats. This enables automated mass production of wooden window slats while significantly reducing labor costs. Attached Figure Description

[0037] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0038] like Figure 1-12 As shown, a wooden louver blade manufacturing device includes a press 1, an upper mold 2, and a lower mold 3. The press 1 includes a hydraulic cylinder 11 and a base 12. The upper mold 2 is connected to the power output end of the hydraulic cylinder 11. The lower mold 3 is mounted on the upper surface of the base 12. The upper surface of the lower mold 3 has several longitudinally arranged forming cavities 31. In this embodiment, there are three forming cavities 31. The lower end of the upper mold 2 has a first mold core assembly 4 and a second mold core assembly 5 that extend into the forming cavity 31. The first mold core assembly 4 includes a first core 41 and a first drive mechanism. The first core 41 is rotatably connected to the upper mold 2. The first drive mechanism is located inside the upper mold 2 and drives the first core 41 to rotate. When the upper mold 2 and the lower mold 3 are closed, the first mold core assembly 4 forms the connecting hole in the middle of the louver blade, and the second mold core assembly 5 forms the connecting holes at both ends of the louver blade.

[0039] In this embodiment, the first driving mechanism includes a gear rack 42, a gear 43, a roller 44, a first driving block 45, and a second driving block 46. The upper mold 2 includes a connecting template 21 and an mounting template 22. The upper end of the connecting template 21 is connected to the hydraulic cylinder 11, and the lower end of the connecting template 21 is connected to the mounting template 22. The upper end of the first core 41 is rotatably connected to the mounting template 22 via a bearing. The gear 43 is sleeved on the upper end of the first core 41. The gear rack 42 is slidably connected within the mounting template 22. The gear rack 42 is meshed with each gear 43. Both ends of the gear rack 42 extend out of the mounting template 22. Rollers 44 are rotatably connected to both ends of the gear rack 42. The first drive block 45 and the second drive block 46 are mounted on the press 1. The first drive block 45 and the second drive block 46 are respectively located on both sides of the gear rack 42. The first drive block 45 has a first abutting surface 451, and the second drive block 46 has a second abutting surface 461. The rollers 44 at both ends of the gear rack 42 abut against the first abutting surface 451 and the second abutting surface 461 respectively.

[0040] To make the connection between the first core 41 and the toothed rack 42 more secure, the upper surface of the mounting template 22 is provided with a mounting groove 221, the mounting groove 221 is provided with a guide groove 222 and a first mounting hole 223, the first core 41 is installed in the first mounting hole 223, the lower end of the toothed rack 42 is slidably connected in the guide groove 222, and the side wall of the mounting template 22 is provided with a through hole for the end of the toothed rack 42 to extend out.

[0041] Specifically, the first abutment surface 451 and the second abutment surface 461 are arc-shaped wavy surfaces. With the above structure, the first abutment surface 451 and the second abutment surface 461 guide the toothed rack 42, driving the toothed rack 42 to repeatedly move laterally during the lifting and lowering process of the upper mold 2.

[0042] In this embodiment, a feeding device 6 is also included. The feeding device 6 includes a feeder 61, a transverse drive device 62, and a longitudinal drive device 63. The transverse drive device 62 includes a first connecting plate 621, a second connecting plate 622, a first motor 623, a first lead screw 624, and a first guide rail 625. Specifically, the feeder 61 can be a commercially available fabric feeder or a screw extruder. The feeder 61 is mounted on the first connecting plate 621. The first motor 623 and the first guide rail 625 are mounted on the second connecting plate 622. The lower end of the first connecting plate 621 is slidably connected to the first guide rail 625. The first lead screw 624 is connected to the power output end of the first motor 623. The lower end of the first connecting plate 621 and the first lead screw 624 are threadedly connected through a first threaded block. The first motor 623 drives the first lead screw 624 to rotate, thereby driving the first connecting plate 621 to move back and forth along the first guide rail 625. The longitudinal drive device 63 includes a third connecting plate 631, a second motor 632, a second lead screw 633, and a second guide rail 634. The second motor 632 and the second guide rail 634 are mounted on the third connecting plate 631. The extension direction of the second guide rail 634 is perpendicular to the extension direction of the first guide rail 625. The lower end of the second connecting plate 622 is slidably connected to the second guide rail 634. The second lead screw 633 is mounted on the power output end of the second motor 632 and is threadedly connected to the lower end of the second connecting plate 622 through a second threaded hole. The second motor 632 drives the second lead screw 633 to rotate, thereby driving the second connecting plate 622 to translate back and forth along the second guide rail 634.

[0043] In this embodiment, a discharge device 7 is also included. The discharge device 7 includes a discharge frame 71, a discharge plate 72, a first conveyor belt 73, and a second conveyor belt 74. The discharge frame 71 is connected to the base 12, and the discharge plate 72 is slidably connected to the discharge frame 71. The length of the discharge plate 72 is three-quarters of the length of the window leaf. The discharge frame 71 is equipped with a cylinder that drives the discharge plate 72 to move horizontally. The cylinder can drive the discharge plate 72 to move to the side of the farthest side of the upper mold 2. The discharge end of the discharge frame 71 is connected to the feed end of the first conveyor belt 73, and the discharge end of the first conveyor belt 73 is connected to the feed end of the second conveyor belt 74.

[0044] A method based on the above-mentioned manufacturing equipment includes the following steps:

[0045] S1. Press 1 drives the upper mold 2 to rise, causing the upper mold 2 to separate from the lower mold 3;

[0046] S2. The longitudinal drive device 63 drives the feeder 61 to enter above the lower mold 3. The feeder 61 conveys materials such as wood chips and adhesives into the molding cavity 31. Then, the transverse drive device 62 cooperates with the longitudinal drive device 63 to drive the conveyor to move laterally repeatedly along the front and back direction of the molding cavity 31, so that the material can be evenly filled into the molding cavity 31. When each molding cavity 31 is filled with material, the longitudinal drive device 63 drives the feeder 61 away from the press 1.

[0047] S3. Press 1 drives the upper mold 2 to descend, so that the upper mold 2 and the lower mold 3 fit together. During the process of the upper mold 2 gradually descending, the rollers 44 at both ends of the toothed row 42 slide and translate repeatedly through the abutting drive of the first abutting surface 451 and the second abutting surface 461, thereby driving the first core 41 to rotate repeatedly in the forward and reverse directions. This facilitates the material in the forming cavity 31 to be discharged outward during the descent of the first core 41, so that the first core 41 can be inserted into the material more smoothly. Afterward, the upper mold 2 and the lower mold 3 close to hot press the material in the forming cavity 31 into a window leaf.

[0048] S4. Press 1 is left to stand for 2 minutes to allow the window leaf in the molding cavity 31 to cool and solidify. Then, press 1 drives the upper mold 2 to rise, causing the upper mold 2 to separate from the lower mold 3. Since the connecting hole of the window leaf is closely fitted with the first core 41 and the second mold core assembly 5, the window leaf is driven to rise and demold together during the process of the upper mold 2 rising.

[0049] S5. When the upper mold 2 rises above the discharge plate 72, the discharge plate 72 is moved below the upper mold 2 by the cylinder. During the upward movement of the upper mold 2, the rollers 44 at both ends of the toothed rack 42 slide and translate repeatedly by the abutting drive of the first abutting surface 451 and the second abutting surface 461, driving the first core 41 to rotate repeatedly in the forward and reverse directions, so that the first core 41 and the window leaf connecting hole generate sliding friction. Through friction, the side wall of the window leaf connecting hole and the side wall of the first core 41 can slide and separate from each other, preventing the side wall of the connecting hole from continuing to stick to the side wall of the first core 41. At this time, the window leaf loses the upward driving force and falls downward onto the discharge plate 72. Then the discharge plate 72 moves toward the first conveyor belt 73, and the first conveyor belt 73 transports the window leaf to the second conveyor belt 74, and then the second conveyor belt 74 collects the window leaf.

[0050] S6. Workers transport the collected window slats to the spraying device for spraying and coloring. After the glue and pigments have dried, they are stored in the warehouse for preservation.

[0051] Compared with existing technologies, the advantages of this invention are that it can form multiple window slats at once, effectively improving the production efficiency of venetian blinds. Simultaneously, during the rising and falling of the upper mold 2, the first driving mechanism drives the first core 41 to continuously rotate and flip, allowing the first core 41 to smoothly extend into the material of the forming cavity 31, facilitating the formation of the connecting hole. During demolding, the sidewall of the connecting hole can be separated from the sidewall of the first core 41, preventing the sidewall of the connecting hole from adhering to the sidewall of the first core 41, thus aiding in rapid demolding of the window slats. This enables automated mass production of wooden window slats while significantly reducing labor costs.

[0052] More preferably, in this invention, the second mold core assembly 5 is provided with a second core 51 extending into the molding cavity 31. The second core 51 includes a fixed core 511 and a swing core 512. The mounting template 22 is provided with a plurality of through-hole second mounting holes 224. The fixed core 511 includes a connecting part 5111 and a molding part 5112 connected vertically. The connecting part 5111 is fixedly installed in the second mounting holes 224. The molding part 5112 extends downward out of the second mounting holes 224. A vertically arranged swing groove 5113 is provided on the side wall of the connecting part 5111 and the molding part 5112. The swing core 512 is rotatably connected in the swing groove 5113. The fixed core 511 is also provided with a swing drive mechanism for driving the swing core 512 to swing. The connecting part 5111 has a vertically arranged vertical groove 5114 on the side wall of the swing groove 5113. The outer side wall of the swing core 512 has a horizontally arranged rotating shaft 5121. The two ends of the rotating shaft 5121 are respectively embedded in the vertical groove 5114. A fixing block 5115 is also embedded in the vertical groove 5114. The fixing block 5115 fixes the rotating shaft 5121 to the bottom end of the vertical groove 5114. With the above structure, the swing core 512 can swing around the rotating shaft 5121.

[0053] In this embodiment, the swing drive mechanism includes a drive sleeve 52, a drive rod 53, and a cover plate 54. The cover plate 54 is fixedly connected to the opening of the second mounting hole 224. The center of the cover plate 54 has a through hole for the drive rod 53 to pass through. The upper end of the drive rod 53 is connected to the connecting template 21, and the lower end of the drive rod 53 extends into the second core 51. The drive sleeve 52 is slidably connected within the second mounting hole 224. The upper end of the drive sleeve 52 is provided with a plurality of spaced-apart sector blocks 521. The sector blocks 521 are spaced apart from the swing core 512 to prevent the drive sleeve 52 from deflecting. The outer side wall of the sector blocks 521 is connected to the second mounting hole 224. The holes 224 fit together, allowing the fan-shaped block 521 to slide more smoothly between the connecting part 5111 and the cover plate 54. The lower end of the drive rod 53 is provided with a push rod 531, and the end of the push rod 531 is provided with a spherical push surface. The lower end of the inner wall of the swing core 512 is provided with a first inclined surface 5122. The first inclined surface 5122 gradually inclines from top to bottom inward. The spherical push surface and the first inclined surface 5122 abut against each other. When the drive rod 53 is at the lowest point, the push rod 531 can abut against the lowest point of the first inclined surface 5122, thereby fixing the swing core 512 in a vertical position. A support arm 522 is provided on the outer wall of the drive sleeve 52 corresponding to the swing core 512. The support arm 522 has a horizontally extending slide groove 5221 and a vertically penetrating drive groove 5222. A slider 5223 is slidably connected within the slide groove 5221. The end of the slider 5223 has an arc-shaped abutment 5224, the front end of which is a semi-circular arc surface. A connecting arm 532 is provided on the drive rod 53 above the abutment rod 531. The connecting arm 532 has an upwardly extending section that passes through the drive groove 5222. The abutting arm 533 has a second inclined surface on the side near the slider 5223. The rear end of the slider 5223 has a wedge-shaped part 5225, which has a third inclined surface that fits with the second inclined surface. A spring is fitted on the slider 5223. One end of the spring abuts against the side wall of the slide groove 5221, and the other end abuts against the side of the wedge-shaped part 5225. The upper end of the inner side wall of the swing core 512 has a fourth inclined surface 5123, which abuts against and fits against the arc-shaped abutting top 5224. With the above structure, when the upper mold 2 moves downward, after the sector block 521 of the drive sleeve 52 is fixed on the connecting part 5111, the drive rod 53 continues to move downward, causing the abutment arm 533 to continue moving downward relative to the support arm 522. Under the action of the spring, the slider 5223 is pushed towards the inside of the support arm 522, at which point the arc-shaped abutment top 5224 separates from the swing core 512. When the upper mold 2 moves upward, the abutment arm 533 moves upward relative to the support arm 522, and the second inclined surface abuts against the third inclined surface, thereby pushing the slider 5223 to slide outward, causing the arc-shaped abutment top 5224 to move outward and contact the inner wall of the swing core 512.

[0054] Specifically, a limiting block is provided at the upper end of the abutment arm 533. The limiting block can prevent the abutment arm 533 from separating from the drive groove 5222, and at the same time, the limiting block can further push the drive sleeve 52 to move downward. The inner wall of the swing core 512 is provided with several horizontally arranged arc-shaped ribs 5124 below the fourth inclined surface 5123. The cross-section of the arc-shaped ribs 5124 is semi-circular. During the upward movement of the drive sleeve 52, since the arc-shaped abutment top 5224 is close to the inner wall of the swing core 512, the arc-shaped abutment top 5224 can contact the arc-shaped ribs 5124, thereby causing the second core 51 to vibrate.

[0055] After the above structure is adopted, after the window leaf is pressed and formed, the hydraulic cylinder 11 drives the connecting template to rise, which in turn drives the drive rod 53 to rise together, so that the drive rod 53 gradually separates from the first inclined surface 5122. The drive rod 53 continues to rise, so that the upper surface of the connecting arm 532 abuts against the lower end of the drive sleeve 52, thereby driving the drive sleeve 52 to rise. The drive sleeve 52 slides upward in the second mounting hole 224 until the upper surface of the fan-shaped block 521 abuts against the lower surface of the cover plate 54, driving the mounting template to move upward and separate from the lower mold 3. During the rising process of the connecting template 21 and the mounting template 22, the abutting arm 533 abuts against the slider 5223, thereby pushing the arc-shaped abutting top 5224 closer to the swing core 512, and the arc-shaped abutting top 5224 abuts against the drive sleeve 52 as it rises. Part 5224 can contact the arc-shaped rib 5124, causing the swing core 512 and the fixed core 511 to vibrate continuously, reducing the adhesion force between the sidewalls of the connecting holes at both ends and the sidewalls of the second core 51, making it easier for the sidewalls of the connecting holes at both ends of the window leaf to separate and demold from the second core 51; when the drive sleeve 52 moves to the uppermost end, the arc-shaped abutment 5224 is pushed to the outermost side, and the arc-shaped abutment 5224 contacts the fourth inclined surface 5123 during the upward process, pushing the upper end of the swing core 512 to swing outward, so that the lower end of the swing core 512 swings towards the inside of the fixed core 511, further reducing the contact area between the second core 51 and the connecting hole of the window leaf. At this time, the window leaf falls onto the discharge plate under its own gravity. Compared with the prior art, the present invention can generate a vibration effect between the second core 51 and the blade when the mold is opened, so as to avoid the side wall of the connecting hole of the blade from being too close to the side wall of the second core 51. At the same time, the swinging core 512 can swing inward during demolding, reducing the contact area between the side wall of the connecting hole and the second core 51, which facilitates the automatic demolding and falling of the window blade during demolding.

[0056] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.

The discharge frame is equipped with a cylinder for driving the discharge plate to move horizontally. The discharge end of the discharge frame is connected to the feed end of the first conveyor belt, and the discharge end of the first conveyor belt is connected to the feed end of the second conveyor belt.

5. A method for manufacturing wooden louver blades based on the equipment described in claim 4, characterized in that, Includes the following steps: S1. The press drives the upper die to rise, causing the upper die and lower die to separate from each other; S2. The longitudinal drive device drives the feeder to enter the upper part of the lower mold. The feeder transports wood chips and adhesive materials into the molding cavity. Then, the transverse drive device works with the longitudinal drive device to drive the conveyor to move laterally repeatedly along the front and back direction of the molding cavity, so that the material can be evenly filled into the molding cavity. When each molding cavity is filled with material, the longitudinal drive device drives the feeder away from the press. S3. The press drives the upper mold to descend, so that the upper mold and the lower mold fit together. During the process of the upper mold gradually descending, the rollers at both ends of the toothed row slide and translate repeatedly through the abutment drive of the first abutment surface and the second abutment surface, thereby driving the first core to rotate repeatedly in the forward and reverse directions. This facilitates the discharge of the material in the forming cavity during the descent of the first core, allowing the first core to extend more smoothly into the material. Afterward, the upper mold and the lower mold close to hot press the material in the forming cavity into a window leaf. S4. The press is left to stand for 2 minutes to allow the window leaf in the molding cavity to cool and solidify. Then the press drives the upper mold to rise, separating the upper mold from the lower mold. Since the connecting hole of the window leaf fits tightly with the first core and the second mold core assembly, the window leaf rises together with the upper mold during the process of the upper mold rising to demold. S5. When the upper mold rises above the ejector plate, the ejector plate moves to below the upper mold via a cylinder. As the upper mold continues to rise, the rollers at both ends of the toothed rack slide and translate repeatedly via the abutment drive of the first and second abutment surfaces, driving the first core to rotate repeatedly in both directions. This causes sliding friction between the first core and the window leaf connecting hole. Through this friction, the sidewall of the window leaf connecting hole and the sidewall of the first core can slide and separate from each other, preventing the sidewall of the connecting hole from continuing to adhere to the sidewall of the first core. At this point, the window leaf loses its upward driving force and falls downward onto the ejector plate. The ejector plate then moves toward the first conveyor belt, which transports the window leaf to the second conveyor belt, where it is then collected. S6. Workers transport the collected window slats to the spraying device for spraying and coloring. After the glue and pigments have dried, they are stored in the warehouse for preservation.
