Description

Technical Field

[0001] The invention relates to the field of cardboard production, and in particular to a device for collecting scraps in a cardboard production process. Background Art

[0002] Cardboard is a sheet-like material pressed from cellulose (usually wood pulp) and is widely used in industries such as packaging, construction, and printing. Depending on its use and manufacturing process, cardboard can be divided into various types, including corrugated cardboard, kraft cardboard, gray cardboard, and thick cardboard.

[0003] Existing thick cardboard needs to be shaped and cut during the production process to ensure that the cardboard has a specific shape. Its cutting equipment mostly uses laser cutting machines. During the actual cutting process, a large amount of scraps are generated. The messy stacking takes up a large space, affecting the overall processing. In addition, after laser cutting, since there is still some contact between the cardboard and the scraps, the staff needs to manually separate them, and the processed cardboard and scraps are collected separately. This process wastes too much manpower and material resources and reduces the overall processing efficiency.

[0004] In summary, a large amount of scraps will be generated during the laser cutting process of cardboard. The messy stacking of scraps takes up a large space, affecting the overall processing. In addition, the staff need to manually separate the cardboard from the scraps, which wastes manpower and material resources and reduces the overall processing efficiency. Summary of the Invention

[0005] Based on this, the purpose of the present invention is to provide a scrap collection device in the cardboard production process to solve the technical problems that the messy stacking of scraps takes up a large space, and the staff need to manually separate the cardboard from the scraps, which wastes the overall manpower and material resources and reduces the overall processing efficiency.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for collecting scraps in a cardboard production process, comprising a workbench and a frame, wherein a conveying mechanism is provided on the workbench, the frame is located on top of the workbench, wherein a laser cutting assembly is slidably provided in the frame, and a fixed gear that cooperates with the laser cutting assembly is rotatably provided inside the frame, wherein one side of the fixed gear is connected to a transmission mechanism, a placement plate is elastically provided on the top of the conveying mechanism, and a top plate that cooperates with the transmission mechanism is provided on the inner side of the conveying mechanism, wherein the top plate is used to lift the placement plate;

[0007] A processing plate is provided on the inner side of the frame, wherein a gear ring is provided on one side of the processing plate on the frame, and a special-shaped gear that cooperates with the gear ring is connected to one side of the fixed gear, wherein the special-shaped gear is used to drive the gear ring to slide back and forth, and a collecting trough is provided on one side of the conveying mechanism on the workbench.

[0008] By adopting the above technical solution, the top plate is driven to move upward through the engagement of the transmission mechanism and the bevel gear, thereby lifting the placement plate on the conveying mechanism and reducing the distance between the placement plate and the processing plate, so that the processed cardboard can fall stably onto the placement plate during the subsequent cutting process. The fixed gear will drive the processing plate to slide back and forth through the gear ring. During this process, the vibration of the processing plate itself will separate the cardboard from the scrap waste. The processed cardboard will be conveyed to the other side under the action of the conveying mechanism, and the waste and cardboard will be separated and collected in this process.

[0009] The present invention is further configured such that a first gear rod is slidably provided in the frame, wherein one side of the first gear rod is engaged with the fixed gear, and the top end of the first gear rod is connected to the laser cutting assembly.

[0010] Preferably, when the cylinder drives the laser cutting assembly to slide, the first gear rod at the bottom will move, thereby driving the fixed gear located in the frame to rotate. The fixed gear can change its rotation direction according to the sliding direction of the laser cutting assembly.

[0011] The present invention is further configured such that a slide is rotatably provided on one side of the frame, wherein a residual gear is connected to one side of the slide, and a second gear rod is elastically engaged with the bottom of the residual gear, one end of the second gear rod is arranged in an arc shape, and a guide plate is provided on one side of the first gear rod.

[0012] Preferably, when the guide plate slides downward under the action of the first gear rod, it will squeeze the second gear rod elastically arranged on one side, and the slide plate will be driven to adjust the rotation angle under the action of the second gear rod. In the process of reciprocating shaking of the processing plate, the slide plate itself will collide with the processing plate, and the impact will act on the cardboard in a short time, ensuring the rapid separation of the cardboard and the scraps. At the same time, when the subsequent slide plate follows the laser cutting assembly to reset, it will play a role in guiding the scraps, so that the scraps can slide steadily into the collection trough.

[0013] The present invention is further configured such that a cylinder is provided on the top of the frame, wherein the output end of the cylinder passes through the frame and is connected to the laser cutting assembly, and the cylinder is used to drive the laser cutting assembly to slide back and forth in the vertical direction.

[0014] Preferably, the cylinder is used to facilitate the staff to control the laser cutting assembly in the frame to slide back and forth in the vertical direction.

[0015] The present invention is further configured such that one end of the transmission mechanism is connected to a rotating shaft, and a positive bevel gear is provided on the rotating shaft, a side bevel gear is engaged with the top of the positive bevel gear, the top of the side bevel gear is connected to a threaded rod, and the outer wall sliding sleeve of the threaded rod is provided with a threaded sleeve, and the top of the threaded sleeve is connected to the top plate.

[0016] Preferably, when the transmission mechanism rotates under the action of the fixed gear, it will drive the rotating shaft at one end to rotate, and the threaded rod will be driven to rotate under the engagement of the positive bevel gear and the side bevel gear. Through the cooperation of the threaded rod and the threaded sleeve, the threaded sleeve can push the top plate upward or retract it downward.

[0017] The present invention is further configured such that a crushing mechanism is provided in the collecting tank, wherein a collecting box is provided on the workbench at the bottom of the crushing mechanism.

[0018] Preferably, the processed cardboard scraps are discharged into the collection box by rollers and crushed and collected by a crushing mechanism, which greatly reduces the space occupied by the scraps. The crushed scraps are collected uniformly through the collection box, reducing the burden of collecting scraps on subsequent staff.

[0019] The present invention is further configured such that the transmission mechanism includes a driving disc, a driven disc and a transmission belt, wherein the driving disc and the driven disc are connected by a transmission belt, one end of the fixed gear is connected to the driving disc, and one end of the driven disc is connected to a rotating shaft.

[0020] Preferably, when the fixed gear rotates through the first gear rod, the driving disc at one end is driven to rotate, and the driven disc is rotated under the action of the transmission belt, thereby driving the rotating shaft to rotate.

[0021] The present invention is further configured such that a plurality of rollers are provided on the processing plate, wherein outer walls of the rollers are configured to be rough.

[0022] Preferably, the roller itself is located on the processing plate and is electrically connected. The roller facilitates driving the processed cardboard to be transported to a collection trough on one side. At the same time, the roughness of the outer wall of the roller effectively increases the sliding friction between the roller and the cardboard, preventing the cardboard from being offset during the processing of the laser cutting component.

[0023] The present invention is further configured such that the inner wall of the frame is symmetrically provided with sliding grooves, and sliding blocks cooperating with the sliding grooves are provided on both sides of the laser cutting assembly.

[0024] Preferably, the cooperation between the slide groove and the slider facilitates the stability of the sliding of the laser cutting component in the frame, ensures the vertical sliding of the laser cutting component, and further improves the overall processing forming rate.

[0025] The present invention is further configured such that an array of support components is provided at the bottom of the workbench, wherein the support components are used to support the workbench.

[0026] Preferably, the support assembly can be used to raise the height of the entire workbench, effectively preventing dirt and impurities on the ground from corroding the cardboard during processing.

[0027] In summary, the present invention mainly has the following beneficial effects:

[0028] 1. The present invention provides a processing plate on the inner side of the frame. The cylinder drives the laser cutting assembly to move downward. During this process, the first gear rod drives the fixed gear to rotate, and the engagement of the transmission mechanism and the bevel gear realizes the upward movement of the top plate, thereby lifting the placement plate on the conveying mechanism and reducing the distance between the placement plate and the processing plate. This facilitates the subsequent stable drop of the processed cardboard onto the placement plate during the cutting process, effectively preventing the processed cardboard from falling onto the side of the workbench.

[0029] 2. The present invention connects a special-shaped gear to one side of the fixed gear, and a gear ring is provided on one side of the processing plate to cooperate with the special-shaped gear. After the subsequent processing is completed, the fixed gear will drive the processing plate to slide back and forth through the gear ring. During this process, the vibration of the processing plate itself will separate the cardboard and scraps, eliminating the need for manual separation by workers, thereby improving the overall processing efficiency.

[0030] 3. The present invention provides a collection box on one side of the workbench. After processing, the processed cardboard scraps are discharged into the collection box by rollers and crushed and collected by a crushing mechanism, which greatly reduces the space occupied by the scraps. The processed cardboard is conveyed to the other side by the conveying mechanism, and the waste and cardboard are separated and collected in the process, saving a lot of manpower and material resources.

[0031] 4. The present invention provides a guide plate on one side of the first gear rod, and a broken gear is rotatably provided on one side of the slide. When the guide plate slides downward under the action of the first gear rod, it will squeeze the second gear rod elastically provided on one side, and the slide will be driven to adjust the rotation angle under the action of the second gear rod. In the process of reciprocating shaking of the processing plate, the slide itself will collide with the processing plate, and the impact will act on the cardboard in a short time, ensuring the rapid separation of the cardboard and the scraps. At the same time, when the subsequent slide follows the laser cutting assembly to reset, it plays a role in guiding the scraps, so that the scraps can slide stably into the collection trough.

[0047] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0048] The following describes an embodiment of the present invention based on its overall structure.

[0049] First embodiment:

[0050] See also Figures 1-11 The device for collecting scraps in a cardboard production process shown in the figure includes a workbench 1, a frame 2, a support assembly 3, a cutting mechanism, a collecting mechanism, and a reciprocating sliding mechanism, wherein a conveying mechanism 10 is provided on the workbench 1, and the frame 2 is located on the top of the workbench 1, a laser cutting assembly 6 is slidingly provided in the frame 2, and a processing plate 7 is symmetrically provided at the bottom of the laser cutting assembly 6 in the frame 2. The worker places the cardboard to be processed on top of the processing plate 7, and then the cylinder 5 drives the laser cutting assembly 6 to move downward and close to the cardboard. Since a first gear rod 23 is slidingly provided in the frame 2, one side of the first gear rod 23 is engaged with the fixed gear 15, when the laser cutting assembly 6 is driven to slide, the first gear rod 23 at the bottom end is moved, thereby driving the fixed gear 15 in the frame 2 to rotate;

[0051] Since a transmission mechanism 27 is connected to one side of the fixed gear 15, and a placement plate 11 is elastically provided on the top of the conveying mechanism 10, and a top plate 18 cooperating with the transmission mechanism 27 is provided on the inner side of the conveying mechanism 10, wherein the top plate 18 is used to lift the placement plate 11. When the laser cutting assembly 6 drives the first gear rod 23 to slide downward, the top plate 18 drives the placement plate 11 to slide upward through the cooperation of the fixed gear 15 and the transmission mechanism 27. At this time, the distance between the placement plate 11 and the thick cardboard will gradually decrease. During the process of the laser cutting assembly 6 processing the thick cardboard, the processed cardboard can stably fall onto the placement plate 11, effectively preventing the processed cardboard from falling to the side of the workbench 1. After the processing is completed, the laser cutting assembly 6 will reset and slide under the action of the cylinder 5.

[0052] Since a gear ring 17 is provided on the frame 2 on one side of the processing plate 7, and a special-shaped gear 16 cooperating with the gear ring 17 is connected to one side of the fixed gear 15, wherein the special-shaped gear 16 is used to drive the gear ring 17 to slide back and forth, therefore, in the process of the first gear rod 23 following the elastic reset of the laser cutting assembly 6, the fixed gear 15 rotates in the opposite direction, at this time, the special-shaped gear 16 will cooperate with the gear ring 17 to drive the processing plate 7 to shake back and forth, during this process, the vibration of the processing plate 7 itself will separate the cardboard and the scrap waste, and there is no need for manual separation work by the staff, which speeds up the overall processing efficiency. The cardboard after processing will be transported to one side under the action of the conveying mechanism 10, and a collecting trough 9 is provided on the workbench 1 on one side of the conveying mechanism 10, and the processed scrap waste is collected through the collecting trough 9, and the separation and collection of waste and cardboard is realized in this process, saving a lot of manpower and material resources.

[0053] In the above embodiment, please refer to Figure 8 and Figure 9 A rotating shaft 28 is connected to one end of the transmission mechanism 27, and a positive bevel gear 22 is provided on the rotating shaft 28, and a side bevel gear 21 is engaged with the top thereof, wherein the top of the side bevel gear 21 is connected to a threaded rod 19, and the outer wall sliding sleeve of the threaded rod 19 is provided with a threaded sleeve 20, and the top of the threaded sleeve 20 is connected to the top plate 18. When the transmission mechanism 27 rotates under the action of the fixed gear 15, it will drive the rotating shaft 28 at one end to rotate, and the threaded rod 19 is driven to rotate under the engagement of the positive bevel gear 22 and the side bevel gear 21. Through the cooperation of the threaded rod 19 and the threaded sleeve 20, the threaded sleeve 20 can realize the top plate 18 being pushed up or retracted downward.

[0054] In the above embodiment, please refer to Figure 4 A crushing mechanism 12 is provided in the collecting trough 9, wherein a collecting box 4 is provided on the workbench 1 at the bottom of the crushing mechanism 12. The processed cardboard scraps are discharged into the collecting box 4 through the roller 14, and at the same time, they are crushed and collected by the crushing mechanism 12, which greatly reduces the space occupied by the scraps. The crushed scraps will be uniformly collected through the collecting box 4, reducing the burden of collecting scraps on subsequent staff.

[0055] In the above embodiment, please refer to Figure 6 An array of rollers 14 is provided on the processing plate 7, wherein the outer wall of the roller 14 is roughened. The roller 14 itself is electrically connected to the processing plate 7. The roller 14 facilitates driving the processed cardboard to be transported to the collecting trough 9 on one side. At the same time, the roughness of the outer wall of the roller 14 effectively increases the sliding friction between the cardboard and the roller 14, thereby preventing the cardboard from being offset during the processing of the laser cutting assembly 6.

[0056] Second embodiment:

[0057] See also Figure 12 and Figure 13 The illustrated device for collecting scraps in a cardboard production process has an overall structure similar to that of the first embodiment, wherein a slide 8 is rotatably provided on one side of the frame 2, wherein a residual gear 24 is connected to one side of the slide 8, and a second gear rod 25 is elastically engaged with the bottom of the residual gear 24, and one end of the second gear rod 25 is arranged in an arc shape. At the same time, a guide plate 26 is provided on one side of the first gear rod 23, and the guide plate 26 itself is arranged in a convex shape. When the guide plate 26 slides downward under the action of the first gear rod 23, it will squeeze the second gear rod 25 elastically arranged on one side, and the slide 8 will be driven to adjust the rotation angle under the action of the second gear rod 25. During the reciprocating shaking of the processing plate 7, the slide 8 itself will collide with the processing plate 7, and the impact will act on the cardboard in a short time, ensuring the rapid separation of the cardboard and the scraps. At the same time, when the subsequent slide follows the laser cutting assembly 6 to reset, it plays a role in guiding the scraps, so that the scraps slide stably into the collection trough 9.

[0058] The present invention works specifically as follows: when in use, the worker places the thick cardboard to be processed on the processing plate 7, and then the cylinder 5 drives the laser cutting assembly 6 in the frame 2 to slide downward. During this process, the laser cutting assembly 6 drives the first gear rod 23 to move, thereby rotating the fixed gear 15 engaged on one side, and rotating the threaded rod 19 under the action of the transmission mechanism 27 and the bevel gear. During this process, the threaded sleeve 20 drives the top plate 18 to lift the placement plate 11, thereby reducing the distance between the placement plate 11 and the processing plate 7. Subsequently, during the cutting process by the laser cutting assembly 6, part of the cardboard will fall onto the placement plate 11, and this process effectively prevents the processed cardboard from falling to one side of the workbench 1;

[0059] And in the process of the cylinder 5 driving the laser cutting assembly 6 to reset, the fixed gear 15 will drive the special-shaped gear 16 to rotate, and in cooperation with the gear ring 17, it will drive the processing plate 7 in the frame 2 to slide back and forth. In this process, the vibration of the processing plate 7 itself causes the cardboard adhered to the scraps to fall off, and there is no need for manual separation by the staff. Then the roller 14 will drive the scraps to be discharged into the collection trough 9 on one side, and it will be crushed by the crushing mechanism 12, which greatly reduces the space occupied by the scraps. At the same time, the conveying mechanism 10 will convey the processed cardboard to the other side, and after the material is taken, the conveying mechanism 10 will reset to facilitate the processing of the next group of cardboards.

[0060] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiment without creative contribution as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
