Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a static pressure conveyor for door panel processing. Background Technology

[0002] When processing reinforcement components for elevators such as door panels, wall panels, car doors, landing doors, and front arms, a conveyor is needed for transporting the components, eliminating the need for manual handling. This not only reduces the workload of the staff but also improves processing efficiency. For example, the prior art patent with publication number "CN118025728A" entitled "An Automatic Door Panel Detection and Conveying Device" discloses a device that can drive a car door panel through a scraping mechanism, a loading mechanism, and a collision mechanism in sequence, enabling the car door panel to complete multiple performance tests at once, improving the detection efficiency of the door panel. Furthermore, the conveying mechanism allows the car door panel to adjust its position and angle during operation, thus adapting to the positions of different detection mechanisms. It can simultaneously test the effects of different materials rubbing against the door panel, effectively simulating different scraping situations encountered by cars in daily use. The collision mechanism can simulate different impact intensities, thereby detecting the maximum impact that the car door panel can withstand. Another example is the prior art patent with publication number "CN11970617". The patent disclosed in 2B is titled "A Conveying Device for Door Panel Processing." It discloses that the conveying unit includes support legs, on which a conveying roller mounting frame is installed. Several conveying rollers are rotatably connected to the conveying roller mounting frame. The door panel is placed at the starting end of the conveying unit, and the door panel is conveyed along the conveying direction of the conveying unit to the door panel quality inspection mechanism. The door panel is inspected by the door panel quality inspection mechanism, and the inspection results are transmitted to the mechanical sorting mechanism. The mechanical sorting mechanism rejects the door panels that fail the quality inspection. When the door panel is conveyed to the tail end of the conveying device, the lifting unit lifts the door panel to a suitable height for receiving by the movable stacking unit. Finally, the door panel is stacked in the movable stacking unit. The use of several conveying units facilitates the maintenance of the conveying device and the modification of the line. The design of the conveying rollers can reduce the wear of the door panel during the conveying process.

[0003] The existing conveyors described above, when conveying reinforcing parts of various products such as door panels, have a relatively simple overall structure. They simply use conveying rollers for transporting and cannot perform static pressure treatment on the reinforcing parts after gluing. As a result, the reinforcing parts may separate during the transport process due to weak adhesion, which in turn prevents the conveyor from effectively transporting the gluing-treated reinforcing parts and affects subsequent processing efficiency. Therefore, we propose a static pressure conveyor for door panel processing to solve the problems mentioned above. Summary of the Invention

[0004] The purpose of this invention is to provide a static pressure conveyor for door panel processing, in order to solve the problem mentioned in the background art that existing conveyors, when conveying reinforcing parts of various products such as door panels, have a relatively simple overall structure and simply use conveying rollers for conveying operations. They cannot perform static pressure treatment on the reinforcing parts of various products after gluing, so the reinforcing parts of various products may separate during the conveying process due to weak adhesion. As a result, the conveyor cannot effectively convey the reinforcing parts of various products after gluing, thus affecting the subsequent processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a static pressure conveyor for door panel processing, comprising a machine body shell for stable placement, and a conveying roller assembly installed on the top of the machine body shell. Inlet and outlet lifting and blocking mechanisms are installed inside the front and rear sides of the machine body shell, and centering mechanisms are symmetrically installed inside the left and right sides of the machine body shell. A row of centering adjusting rollers is installed on a movable plate within the centering mechanism. A support frame is connected to the top of the machine body shell via a linear guide rail, and a static pressure mechanism is connected to the bottom of the support frame.

[0006] Preferably, the inlet / outlet lifting and blocking mechanism includes a fixed plate installed inside the front and rear sides of the machine body shell, and a regulating cylinder is installed below the fixed plate. The output end of the regulating cylinder passes through the interior of the fixed plate and is connected to the support plate. A row of baffles is installed above the support plate, and the baffles are located below the conveying roller assembly. The highest point of the baffles after rising is higher than the highest point of the conveying roller assembly.

[0007] Preferably, a drive gear is rotatably installed inside the outer casing of the machine body located below the conveying roller assembly, and a second rack assembly is meshed with both the front and rear sides of the drive gear. The central mechanism includes a movable plate installed at the outer end of the second rack assembly, and the two movable plates move towards each other. A guide rail assembly is installed inside the outer casing of the machine body, and a movable plate is slidably connected to the guide rail assembly.

[0008] Preferably, the highest point of the centering adjusting roller is higher than the highest point of the conveying roller assembly, and the centering adjusting roller is disposed in the space between two adjacent conveying roller assemblies, and the highest point of the moving plate is lower than the lowest point of the conveying roller assembly.

[0009] Preferably, a rotating rod is rotatably mounted on the left side of the support frame, and transmission gears are keyed to the outer sides of both the front and rear ends of the rotating rod. A servo motor is mounted at the front end of the rotating rod. First rack assemblies are fixed on the upper front and rear sides of the outer shell of the machine body, and transmission gears are meshed on the upper part of the first rack assemblies.

[0010] Preferably, a static pressure cylinder is installed inside the support frame, and a support plate is fixed to the lower output end of the static pressure cylinder. A synchronous lifter is fixed above the support plate, and the upper part of the synchronous lifter is slidably connected to the inside of the support frame. A manual telescopic rod is fixed through the inside of the support plate, a connecting plate is fixed to the lower end of the manual telescopic rod, and a return spring is nested on the lower outer side of the manual telescopic rod.

[0011] Preferably, an opening and closing control cylinder is fixed on the upper front and rear sides of the connecting plate, and a mounting plate is fixed on both the left and right ends of the opening and closing control cylinder. The static pressure mechanism includes a static pressure head installed below the mounting plate.

[0012] Preferably, the static pressure head is a plate structure, and one end of the static pressure head is designed with an intermittent hollow pattern.

[0013] Preferably, a contact plate is provided in the space between two adjacent conveying roller assemblies. The width of the contact plate is less than the shortest distance between the two adjacent conveying roller assemblies. Accommodation grooves are staggered on both the left and right sides of the contact plate. A limit rod is fixed at the opening of the accommodation groove. An adjustment frame is inserted into the accommodation groove. The end of the adjustment frame near the accommodation groove is set with an inclined surface. The end of the adjustment frame away from the accommodation groove is connected to a moving plate. A through groove is opened inside the adjustment frame. A limit rod is installed through the through groove.

[0014] Preferably, the upper and lower surfaces of the control frame are equipped with ball bearings, the opening end of the receiving groove is rounded, the highest point of the contact plate is on the same horizontal plane as the highest point of the conveying roller assembly, and the contact plate is configured as a lifting structure through the control frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the static pressure conveyor for door panel processing can further improve the bonding stability of various product reinforcement parts, and avoid the separation of various product reinforcement parts due to weak bonding or slight shaking during transportation. Therefore, it is convenient for the conveyor to stably transport various product reinforcement parts, which can meet different usage requirements. The specific details are as follows: The output end of the static pressure cylinder drives the support plate and the connecting plate to descend together, which in turn causes the connecting plate to move the static pressure head downward. This allows the static pressure head to apply a certain pressure to the various product reinforcements after the adhesive coating process, thereby further improving the bonding stability of the various product reinforcements and preventing them from separating during the later transportation process due to weak bonding or slight shaking during transportation. Therefore, it is convenient for the conveyor to stably transport various product reinforcements and can meet different usage requirements. Furthermore, by controlling the opening and closing of the cylinder, two mounting plates can be moved towards each other simultaneously, which in turn causes the two mounting plates to drive the static pressure head below to move towards each other, making it easy to adjust the working position of the static pressure head. At the same time, the tail of the static pressure head can be made into an intermittent hollowed-out style in accordance with the length variation of the door panel. By using the second rack assembly in conjunction with the drive gear, the two moving plates can be driven to move inward simultaneously, thus causing the two rows of centering adjustment rollers to move inward synchronously to center and clamp the door panel.

[0016] The two moving plates will drive the two rows of control frames to move inward simultaneously, so that the inclined surface of one end of the control frame enters the contact plate, causing the contact plate to move upward automatically. The highest point of the contact plate is on the same horizontal plane as the highest point of the conveyor roller assembly, which in turn makes the bottom surface of the door panel contact the contact plate and the upper surface of the conveyor roller assembly. Therefore, by supporting the bottom surface of the door panel through the contact plate, deformation or damage to the door panel can be avoided during static pressure in the later stage.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-15 The present invention provides the following technical solution: Example 1: The static pressure conveyor for door panel processing in this example can apply a certain pressure to various product reinforcements after adhesive coating, thereby further improving the bonding stability of various product reinforcements and preventing them from separating during subsequent conveying due to weak bonding or slight shaking during conveying. See attached diagram for the specific structure. Figures 1-11 As shown, the machine includes a housing 1 for stable placement, and a conveying roller assembly 2 is installed on the top of the housing 1. Inlet and outlet lifting and blocking mechanisms are installed inside the front and rear sides of the housing 1, and centering mechanisms are symmetrically installed inside the left and right sides of the housing 1. A row of centering adjusting rollers 6 is installed on the moving plate 7 inside the centering mechanism. A support frame 5 is connected to the top of the housing 1 through a linear guide rail, and a static pressure mechanism is connected to the bottom of the support frame 5.

[0021] The entrance / exit lifting and blocking mechanism includes fixed plates 302 installed inside the front and rear sides of the machine body shell 1. A regulating cylinder 303 is installed below the fixed plate 302, and the output end of the regulating cylinder 303 passes through the interior of the fixed plate 302 and connects to the support plate 301. A row of baffles 3 is installed above the support plate 301, and the baffles 3 are located below the conveyor roller assembly 2. The highest point of the baffles 3 after rising is higher than the highest point of the conveyor roller assembly 2. An active mechanism is rotatably installed inside the machine body shell 1 below the conveyor roller assembly 2. The gear 10 is meshed with the second rack assembly 9 on both the front and rear sides of the drive gear 10. The centering mechanism includes a movable plate 7 installed on the outer end of the second rack assembly 9. The two movable plates 7 move towards each other. A guide rail assembly 8 is installed inside the outer casing 1. The movable plate 7 is slidably connected to the guide rail assembly 8. The highest point of the centering adjusting roller 6 is higher than the highest point of the conveying roller assembly 2. The centering adjusting roller 6 is set in the space between two adjacent conveying roller assemblies 2. The highest point of the movable plate 7 is lower than the lowest point of the conveying roller assembly 2.

[0022] A rotating rod 11 is rotatably mounted on the left side of the support frame 5, and transmission gears 111 are keyed to the outer sides of both ends of the rotating rod 11. A servo motor 112 is mounted on the front end of the rotating rod 11. First rack assemblies 4 are fixed on the upper sides of both the front and rear sides of the outer casing 1, and transmission gears 111 are meshed with the upper parts of the first rack assemblies 4. A static pressure cylinder 12 is installed inside the support frame 5, and a support plate 14 is fixed to the lower output end of the static pressure cylinder 12. A synchronous lifter 13 is fixed above the support plate 14, and the upper part of the synchronous lifter 13 is connected to... The support frame 5 has a through sliding connection inside, and a manual telescopic rod 19 is fixed inside the support plate 14. A connecting plate 15 is fixed to the lower end of the manual telescopic rod 19. A return spring 191 is nested and connected to the lower outer side of the manual telescopic rod 19. Opening and closing control cylinders 16 are fixed on the upper front and rear sides of the connecting plate 15, and mounting plates 17 are fixed to the left and right ends of the opening and closing control cylinders 16. The static pressure mechanism includes a static pressure head 18 installed below the mounting plate 17. The static pressure head 18 is a plate structure, and one end of the static pressure head 18 is designed with an intermittent hollow style.

[0023] First, the door panel is placed on the conveyor roller assembly 2. Then, the conveyor roller assembly 2 rotates to convey the door panel, positioning it below the static pressure mechanism. At this point, the regulating cylinder 303 is activated. The output of the regulating cylinder 303 drives the support plate 301 and the stop post 3 to move upward, so that the highest point of the stop post 3 is higher than the highest point of the conveyor roller assembly 2. The stop post 3 then blocks the inlet and outlet of the conveyor. Next, the control motor inside the machine casing 1 is activated to drive the drive gear 10 to rotate. When the drive gear 10 rotates, it drives the two sets of meshing second rack assemblies 9 on the outer side to move inward simultaneously. The second rack assemblies 9 drive the moving plate 7 to move inward. The moving plate 7 moves inward stably through the guide rail assembly 8, thus causing the moving plate 7 to drive the centering adjusting roller 6 to move inward stably. This causes the two rows of centering adjusting rollers 6 to move inward synchronously to center and clamp the door panel. Next, the servo motor 112 is started, which drives the rotating rod 11 to rotate. (The servo motor 112 is installed on the left side of the support frame 5, and the output end of the servo motor 112 is connected to the rotating rod 11 through a bevel gear set. Since this part is existing technology, it is not shown in detail in the figure.) When the rotating rod 11 rotates, it drives the transmission gears 111 on the outer sides of the front and rear ends to rotate together. Since the transmission gears 111 are meshed with the fixed first rack assembly 4, the transmission gears 111 can drive the support frame 5 to move. At this time, the front and rear ends of the support frame 5 slide left and right on the outer shell 1 through the linear guide rail, so that the support frame 5 slides to the middle position of the outer shell 1. Since the power output of the rotating rod 11 is at both ends, it can prevent the two ends of the rotating rod 11 from being out of sync during operation.

[0024] Then, the opening and closing control cylinder 16 is activated. The opening and closing control cylinder 16 drives the two mounting plates 17 to move outward simultaneously. The two mounting plates 17 drive the static pressure head 18 below to move outward. At this time, the upper surface of the mounting plate 17 slides stably on the bottom surface of the connecting plate 15 through the linear guide rail, thus facilitating the adjustment of the working position of the static pressure head 18. (See attached...) Figure 11As shown, the tail of the static pressure head 18 can be made into an intermittent hollowed-out style according to the length variation of the door panel. Then, the static pressure cylinder 12 is activated. The output end of the static pressure cylinder 12 drives the support plate 14 and the connecting plate 15 to move downward. The synchronous lifter 13 guides the support plate 14, thereby ensuring that the support plate 14 moves downward stably. During the downward pressing process, multiple sets of static pressure heads 18 horizontally and synchronously contact the upper surface of the door panel. Then, the support plate 14 continues to move downward. At this time, the manual telescopic rod 19 is squeezed and retracted, the return spring 191 stores force, and then the support plate 14 stops moving downward, thus making the static pressure head 18. Apply a certain pressure to the reinforcing parts of various products after the glue coating process, thereby further improving the bonding stability of the reinforcing parts and preventing the reinforcing parts of various products from separating due to weak bonding or slight shaking during transportation. Therefore, it is convenient for the conveyor to stably transport the reinforcing parts of various products and meet different usage requirements. After static pressure for a period of time, the static pressure cylinder 12 drives the static pressure mechanism to move upward and reset. Then the centering mechanism and the inlet and outlet lifting and blocking mechanism are reset. Then the conveying roller assembly 2 is started to continue the conveying operation of the door panel.

[0025] When the conveyed product is a wall panel, the entrance / exit lifting and blocking mechanism and the centering mechanism reset, and the conveyor roller assembly 2 is started to convey the wall panel. When the conveyed product is a landing door, the same principle applies as described above: first, the static pressure mechanism is moved to center, then the static pressure head 18 is controlled to move downwards to contact the surface of the reinforcing rib, and static pressure is applied for 5 seconds (time adjustable). After the static pressure process is completed, the static pressure mechanism, the centering mechanism, and the entrance / exit lifting and blocking mechanism reset, and then the conveyor roller assembly 2 is started to convey the landing door. When the conveyed product is an elevator door, the position and concave / convex direction of the reinforcing rib are determined by an external laser sensor. Mounting plate 17 performs opening and closing actions based on feedback. Static pressure cylinder 12 starts and drives mounting plate 17 to move downward. Mounting plate 17 contacts the surface of reinforcing rib and static pressure is applied for 5 seconds (time adjustable). After the static pressure process is completed, the moving static pressure mechanism, centering mechanism, and entrance / exit lifting and blocking mechanism are reset. Then, the conveying roller assembly 2 is started to convey the car door. When the conveyed product is the left front wall, the centering mechanism and entrance / exit lifting and blocking mechanism are reset, and the conveying roller assembly 2 is started to convey the left front wall. When the conveyed product is the right front wall, the right front wall needs to complete the static pressure process first before the conveying operation.

[0026] Example 2: The static pressure conveyor for door panel processing in this example, based on Example 1, increases the contact area between the conveyor and the bottom surface of the door panel by setting the contact plate 20, thereby avoiding deformation or damage to the door panel during subsequent static pressure. See attached diagram for the specific structure. Figures 12-15As shown, a contact plate 20 is provided in the space between two adjacent conveyor roller assemblies 2. The width of the contact plate 20 is less than the shortest distance between the two adjacent conveyor roller assemblies 2. The left and right sides of the contact plate 20 are staggered with receiving grooves 23. A limit rod 22 is fixed at the opening of the receiving groove 23. An adjustment frame 21 is inserted into the receiving groove 23. The end of the adjustment frame 21 near the receiving groove 23 is set with an inclined surface. The end of the adjustment frame 21 away from the receiving groove 23 is connected to the moving plate 7. A through groove 211 is opened inside the adjustment frame 211. The limit rod 22 is installed through the through groove 211. Ball bearings 212 are installed on the upper and lower surfaces of the adjustment frame 21. The opening end of the receiving groove 23 is rounded. The highest point of the contact plate 20 is on the same horizontal plane as the highest point of the conveyor roller assembly 2. The contact plate 20 forms a lifting structure through the adjustment frame 21.

[0027] When the two movable plates 7 move inward, they will drive the two rows of control frames 21 to move inward together. At this time, the inclined surface of one end of the control frame 21 enters the receiving groove 23 in the contact plate 20. At this time, the ball bearings 212 on the outside of the control frame 21 contact the inner wall of the receiving groove 23 in the contact plate 20, which can reduce friction. At this time, the limit rod 22 slides in the through groove 211. Since one end of the control frame 21 is set with an inclined surface, the control frame 21 pushes the contact plate 20 to move upward automatically. At this time, the highest point of the contact plate 20 is on the same horizontal plane as the highest point of the conveying roller assembly 2. Then, the bottom surface of the door panel contacts the upper surface of the contact plate 20 and the conveying roller assembly 2. Therefore, by supporting the bottom surface of the door panel through the contact plate 20, deformation or damage to the door panel can be avoided during static pressure in the later stage, thus completing a series of operations.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
