Description

Technical Field

[0001] This invention relates to a self-leveling method for coating adhesion. Background Technology

[0002] Coating printing refers to the process of applying coatings evenly to a substrate. This process requires the use of a stacking and feeding mechanism to supply materials.

[0003] However, the existing stacking feeding mechanism is relatively long and occupies a large area; the production line conveyor required for normal leveling can reach 60-100 meters depending on the production line speed, and the coating leveling requires a fixed time.

[0004] Therefore, there is a need for a stacked circular feeding mechanism that achieves leveling through repeated stacking and reduces space occupation. Summary of the Invention

[0005] To address the shortcomings of existing devices, the present invention aims to provide a self-leveling method for coating adhesion, comprising the following steps:

[0006] S1. The coating adherents are horizontally fed one by one into the tray located at the receiving station of the rising unit in the stacked circulating feeding mechanism;

[0007] S2. The pallet on the receiving station is sent to the rising transition station by the cam lifting check assembly, and then sent to the rising station by the cam lifting check assembly.

[0008] S3. The pallet at the rising station is lifted up by the pallet below until it reaches the translation station located at the top of the rising unit.

[0009] S4. The pallet located on the translation station is moved horizontally to the descent pause station at the top of the descent unit via the upper translation mechanism.

[0010] S5. Under the action of the cam stop mechanism, the pallet located at the descent pause station moves all the pallets in the descent unit upward until it lifts the pallet located at the descent pause station. At this time, the pallet located at the descent pause station separates from the upper translation mechanism.

[0011] S6. The cam stop mechanism drives the pallets in the lowering unit to descend to the lowering transition position. At this time, the cam stop mechanism lifts up all the pallets in the lowering unit.

[0012] S7. The cam stopping mechanism drives the pallets down to the discharge station one by one. The pallets that reach the discharge station are moved horizontally by the lower translation mechanism to the pallet rising and recycling station in the rising unit. The paint adhering in the pallets that reach the discharge station is sent to the next process by the belt conveyor.

[0013] S8. The pallet located in the pallet lifting and recycling station within the lifting unit is lifted to the receiving station by the action of the cam lifting check component.

[0014] S9. Repeat steps S1-S8.

[0015] In a further preferred embodiment of the technical solution of the present invention, in S1, the coating adherent is conveyed to the stacking and circulating feeding mechanism by a conveyor belt and thrown into the tray of the receiving station by inertial force.

[0016] A further optimization of the technical solution of the present invention involves stacking several pallets within the stacked circular feeding mechanism.

[0018] In a further preferred embodiment of the technical solution of the present invention, both the cam lifting check assembly and the cam stopping mechanism include a back plate, a movable plate, a pair of movable supports, and a pair of fixed supports mounted on a frame. The movable plate is slidably mounted on the back plate via a linear guide pair, and a cam mounted on the back plate pushes a convex shaft on the movable plate, causing the movable plate to move linearly on the back plate. The cam is driven by a motor. The pair of movable supports are symmetrically mounted on the movable plate, and the pair of fixed supports are symmetrically mounted on the back plate.

The cam stopping mechanism also includes two scrapers, which are respectively mounted on the pair of movable supports and extend to the fixed supports. When the scrapers descend with the movable plate, they are used to press down and retract the second movable supports.

[0019] In a further preferred embodiment of the technical solution of the present invention, both the first movable support block and the second movable support block are provided with an upward-facing flat surface for placing the tray and a downward-facing inclined surface for pushing and retracting.

The lower translation mechanism is arranged on the lower part of the equipment frame, and the hooks in the lower translation mechanism are located at the discharge station.

[0021] A further preferred embodiment of the technical solution of the present invention is that a coating adhesion position adjustment component is provided on the equipment frame of the descent unit.

The mounting frame is provided on the equipment frame, the housing of the electric push rod is provided on the mounting frame, and the push rod end of the electric push rod is connected to the adjustment rod via a connecting plate. Magnets are installed at the ends of the adjustment rods.

[0022] In a further preferred embodiment of the technical solution of the present invention, the tray is a square plate, and guide wheels are provided at the four corners of the tray. Skirts are provided on the edges of the two symmetrical sides of the upper part of the tray. Hook holes that cooperate with hooks are provided on the skirts. On the side of the tray without skirts, slots are opened from the edge inward for the insertion of adjustment rods. The slots penetrate the upper and lower surfaces of the tray.

[0023] A further preferred embodiment of the technical solution of the present invention is that a belt conveyor is installed at the discharge station via a frame to transport the coating adhered material away.

[0034] The technical solution of the present invention will be described in detail below, but the scope of protection of the present invention is not limited to the embodiments described.

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the following description is provided in conjunction with the appendix. Figure 1-6 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] like Figure 1 As shown, this embodiment is a self-leveling method for coating attachments. This method uses a folding cycle to self-level the coating attachments, effectively shortening the length of the occupied space and meeting the self-leveling time requirement. Figure 1 The hollow arrow in the diagram indicates the cyclical movement path of tray 6.

[0037] A self-leveling method for coating adhesion includes the following steps:

[0038] S1. The coating adherents are horizontally fed one by one into the tray 6 located at receiving station B of the rising unit in the stacked circulating feeding mechanism;

[0039] S2. The pallet on receiving station B is sent to the rising transition station C by the cam lifting check assembly 1, and then sent to the rising station D by the cam lifting check assembly;

[0040] S3. The pallet at the rising station D is lifted up by the pallet below until it rises to the translation station E located at the top of the rising unit.

[0041] S4. The pallet located on the translation station E is moved horizontally to the descent pause station F at the top of the descent unit via the upper translation mechanism;

[0042] S5. Under the action of the cam stop mechanism 2, the pallet located on the descent pause station F drives all the pallets in the descent unit to move upward until it lifts the pallet located on the descent pause station F. At this time, the pallet located on the descent pause station F separates from the upper translation mechanism.

[0043] S6. The cam stop mechanism 2 drives the pallet in the lowering unit to descend to the lowering transition position G. At this time, the cam stop mechanism 2 lifts up all the pallets in the lowering unit.

[0044] S7. The cam stopping mechanism drives the pallets down to the discharge station H one by one. The pallets that reach the discharge station are moved horizontally by the lower translation mechanism to the pallet rising and recycling station A in the rising unit. The paint adhering in the pallets that reach the discharge station is sent to the next process by the belt conveyor.

[0045] S8. The pallet located on the pallet rising and circulating recovery station A in the rising unit is lifted to the receiving station B under the action of the cam lifting check component 1.

[0046] S9. Repeat steps S1-S8.

[0047] like Figure 2 As shown, in relation to the self-leveling method of the coating adhesion in this embodiment, this embodiment proposes a stacked circulating feeding mechanism, which is used in conjunction with the leveling production line in the known art. The stacked circulating feeding mechanism in this embodiment adopts stacked circulating feeding, which greatly reduces the space occupation.

[0048] The coating adherent is conveyed by the conveyor belt on the leveling production line to the stacking and circulating feeding mechanism, and then thrown into the tray at the receiving station by inertial force.

[0049] like Figure 2 As shown, several trays 6 are stacked inside the stacking and circulating feeding mechanism, and the trays 6 circulate and transport the coating material inside the stacking and circulating feeding mechanism.

[0050] like Figure 2 As shown, the stacking and circulating feeding mechanism includes a lifting unit and a lowering unit, which share a set of equipment frame 3. Two cam lifting check components 1 are symmetrically arranged in the lifting unit, and two cam stopping mechanisms 2 are symmetrically arranged in the lowering unit. The space below the equipment frame 3 is left empty to accommodate the drive components instead of placing the tray 6.

[0051] like Figure 2 and 3 The function of the cam-lifting check valve assembly 1 is as follows: First, it supports the pallet at the rising transition station C, then lowers to support the pallet 6 at the rising circulation recovery station A, and lifts it to the receiving station B, where it receives the delivered paint adherent. Then it is lifted back to the rising transition station C, where the lower pallet 6 supports the upper pallet. Finally, it is lifted to the rising station D. This process is repeated.

[0052] like Figure 3 As shown, the cam lifting check assembly 1 includes a back plate 11, a movable plate 12, a pair of movable supports 13, and a pair of fixed supports 14 mounted on the frame. The back plate 11 is mounted on the equipment frame 3. The movable plate 12 is slidably mounted on the back plate 11 via a linear guide pair 17. The cam 15 mounted on the back plate 11 pushes the cam shaft 16 on the movable plate 12, causing the movable plate 12 to move linearly on the back plate 11. The cam 15 is driven by a motor. The pair of movable supports 13 are symmetrically mounted on the movable plate 12, and the pair of fixed supports 14 are symmetrically mounted on the back plate 11.

[0053] like Figure 3 As shown, in this embodiment, two linear guide rail pairs slide 17 are provided between the movable plate 12 and the back plate 11, and the two linear guide rail pairs slide 17 are located at both ends of the movable plate 12.

[0054] like Figure 3 As shown, in this embodiment, the cam 15 is mounted on the back plate 11 via a camshaft, and a transmission sprocket is mounted at the end of the camshaft. The cam is connected to the motor via chain drive, and the motor is positioned in the space below the equipment frame 3. The cam 15 is positioned between two linear guide pairs sliding 17.

[0055] like Figure 3 As shown, a pair of movable supports 13 are symmetrically arranged on the movable plate 12, and follow the movable plate 12 in a linear reciprocating motion. A pair of fixed supports 14 are symmetrically arranged on the back plate 11.

[0056] like Figure 3 As shown, each movable support 13 in the cam lifting check assembly 1 includes two first movable supports 131 arranged vertically, and each fixed support 14 includes two second movable supports 141 arranged vertically. The first movable supports 131 and the second movable supports 141 are movably mounted by a pin, and each of the first movable supports 131 and the second movable supports 141 is provided with a return torsion spring 18. The specific installation of the return torsion spring 18 is as follows:

[0057] The installation relationship between the first movable support block 131 and the reset torsion spring 18 is as follows: countersunk holes are provided on the movable support 13 and the first movable support block 131 respectively, and the two ends of the reset torsion spring 18 are respectively installed into the two countersunk holes, and the reset torsion spring 18 and the pin of the first movable support block 131 form a spatial perpendicular relationship.

[0058] The installation relationship between the second movable support block 141 and the reset torsion spring 18 is as follows: countersunk holes are provided on the fixed support 14 and the second movable support block 141 respectively, and the two ends of the reset torsion spring 18 are respectively installed into the two countersunk holes, and the reset torsion spring 18 and the pin of the second movable support block 141 form a spatial perpendicular relationship.

[0059] like Figure 3 As shown, both the first movable support block 131 and the second movable support block 141 are provided with an upward-facing flat surface for placing the tray and a downward-facing inclined surface for pushing and retracting.

[0060] like Figure 3 As shown, the specific structure of the first movable support block 131 and the second movable support block 141 being movably mounted via pins is as follows:

[0061] The first movable support block 131 and the movable support 13 are movably installed together by a pin. Specifically, a long slot is opened on the movable support 13 to embed the first movable support block 131. The first movable support block 131 is inserted into the long slot and the pin is inserted through it.

[0062] The second movable support block 141 is movably installed with the fixed support block 14 via a pin. Specifically, a long slot is opened on the fixed support block 14 to accommodate the second movable support block 141. The second movable support block 141 is inserted into the long slot and the pin is inserted through it.

[0063] like Figure 2 and 3 As shown, the detailed working process of the cam lifting check assembly 1 is as follows:

[0064] 1. Define the initial state. At this time, the fixed support 14 supports two trays 6, and the second movable support block 141 with upper and lower layers supports them. At this time, there are no trays 6 on the movable support 13.

[0065] 2. The cam 15 of the cam lifting check assembly 1 moves under the action of the motor. The cam 15 rotates and pushes the cam shaft 16, which drives the moving plate 12 to move relative to the back plate 11 on the linear guide pair. The moving plate 12 moves downward, and the two lower first movable support blocks 131 on the moving support 13 lift the pallet 6 located on the pallet rising and recycling station A (lower translation mechanism - chain). The two upper first movable support blocks 131 lift the pallet 6 on the two lower second movable support blocks 141 on the fixed support 14.

[0066] At this time, the cam 15 continues to rotate, the moving plate 12 moves upward, and when it reaches the receiving station B, the tray 6 supported by the two lower first movable blocks 131 on the moving tray 13 receives the delivered paint adherent.

[0067] As the cam 15 continues to rotate, the moving plate 12 moves upward. When it reaches the rising transition station C, the pallet lifted by the two upper first movable blocks 131 on the moving pallet 13 is sent to the two upper second movable blocks 141 on the fixed pallet 14. The pallet 6 originally lifted by the two upper second movable blocks 141 on the fixed pallet 14 enters the rising station D. The pallet 6 lifted by the two lower first movable blocks 131 on the moving pallet 13 (from the pallet rising cycle recovery station A) is sent to the two lower second movable blocks 141 on the fixed pallet 14.

[0068] This process is repeated in a loop.

[0069] like Figure 2 and 4 As shown, the cam stop mechanism 2 includes a back plate 11, a movable plate 12, a pair of movable supports 13 and a pair of fixed supports 14 mounted on the frame. The back plate 11 is mounted on the equipment frame 3. The movable plate 12 is slidably mounted on the back plate 11 via a linear guide pair 17. The cam 15 mounted on the back plate 11 pushes the cam shaft 16 on the movable plate 12, causing the movable plate 12 to move linearly on the back plate 11. The cam 15 is driven by a motor. The pair of movable supports 13 are symmetrically mounted on the movable plate 12, and the pair of fixed supports 14 are symmetrically mounted on the back plate 11.

[0070] like Figure 4As shown, in this embodiment, two linear guide rail pairs slide 17 are provided between the movable plate 12 and the back plate 11, and the two linear guide rail pairs slide 17 are located at both ends of the movable plate 12.

[0071] like Figure 4 As shown, in this embodiment, the cam 15 is mounted on the back plate 11 via a camshaft, and a transmission sprocket is mounted at the end of the camshaft. The cam is connected to the motor via chain drive, and the motor is positioned in the space below the equipment frame 3. The cam 15 is positioned between two linear guide pairs sliding 17.

[0072] like Figure 4 As shown, a pair of movable supports 13 are symmetrically arranged on the movable plate 12, and follow the movable plate 12 in a linear reciprocating motion. A pair of fixed supports 14 are symmetrically arranged on the back plate 11.

[0073] like Figure 4 As shown, each movable support 13 in the cam stop mechanism 2 includes a first movable support block 131, and each fixed support 14 includes a second movable support block 141; the first movable support block 131 and the second movable support block 141 are movably mounted by a pin, and both the first movable support block 131 and the second movable support block 141 are provided with a return torsion spring 18. The specific installation of the return torsion spring 18 is as follows:

[0074] The installation relationship between the first movable support block 131 and the reset torsion spring 18 is as follows: countersunk holes are provided on the movable support 13 and the first movable support block 131 respectively, and the two ends of the reset torsion spring 18 are respectively installed into the two countersunk holes, and the reset torsion spring 18 and the pin of the first movable support block 131 form a spatial perpendicular relationship.

[0075] The installation relationship between the second movable support block 141 and the reset torsion spring 18 is as follows: countersunk holes are provided on the fixed support 14 and the second movable support block 141 respectively, and the two ends of the reset torsion spring 18 are respectively installed into the two countersunk holes, and the reset torsion spring 18 and the pin of the second movable support block 141 form a spatial perpendicular relationship.

[0076] like Figure 4 As shown, both the first movable support block 131 and the second movable support block 141 are provided with an upward-facing flat surface for placing the tray and a downward-facing inclined surface for pushing and retracting.

[0077] like Figure 4 As shown, the specific structure of the first movable support block 131 and the second movable support block 141 being movably mounted via pins is as follows:

[0078] The first movable support block 131 and the movable support 13 are movably installed together by a pin. Specifically, a long slot is opened on the movable support 13 to embed the first movable support block 131. The first movable support block 131 is inserted into the long slot and the pin is inserted through it.

[0079] The second movable support block 141 is movably installed with the fixed support block 14 via a pin. Specifically, a long slot is opened on the fixed support block 14 to accommodate the second movable support block 141. The second movable support block 141 is inserted into the long slot and the pin is inserted through it.

[0080] like Figure 4 As shown, the cam stop mechanism 2 also includes two scrapers 21, which are respectively mounted on a pair of movable supports 13. The scrapers 21 extend to the fixed support 14. When the scrapers 21 follow the movable plate 12 down, they are used to press down and retract the second movable support block 141.

[0081] like Figure 4 As shown, two slide rail pairs are provided between the scraper 21 and the movable support 13. The two slide rails are fixed on both sides of the movable support 13, and the linear sliding direction of the two slide rail pairs is parallel to the linear sliding direction of the movable support 13. The scraper 21 is also connected to the slider of the two slide rail pairs, and one end extends to the fixed support 14. A compression spring 22 is provided between the scraper 21 and the movable support 13. The extension and retraction direction of the compression spring 22 is parallel to the sliding direction of the scraper 21. The installation relationship between the compression spring 22 and the scraper 21 and the movable support 13 is as follows: countersunk holes are provided at corresponding positions on both the scraper 21 and the movable support 13, and the two ends of the compression spring 22 are respectively inserted into the two countersunk holes.

[0082] During operation, when the movable support 13 moves upward, it drives the scraper 21 to move upward as well. When the scraper 21 contacts the second movable support block 141, under the restoring force of the compression spring 22, the scraper 21 pushes the second movable support block 141 to retract into the long groove. At this time, the tray 6 can fall to the discharge station.

[0083] like Figure 1 and 4 As shown, the detailed working process of the cam stop mechanism 2 is as follows:

[0084] 1. Definition: Within the descending unit, the pallet in the stacked circular feeding mechanism is supported by a pair of movable pallets 13 and a pair of fixed pallets 14. This is defined as the initial state.

[0085] 2. The coating adherent that needs to be transmitted:

[0086] 2.1 As the cam rises, the cam 15 of the cam stop mechanism 2 moves under the action of the motor. The cam 15 pushes the cam shaft 16, causing the moving plate 12 to move relative to the back plate 11 on the linear guide pair. The moving plate 12 moves upward, and at this time, the pallet 6 at the lowering transition station C and above is supported by a pair of fixed supports 13 and movable supports 131. At the same time, the compression spring 22 pushes the scraper 21, and the scraper 21 pushes the second movable support 141.

[0087] 2.2 The cam descends, and the cam 15 of the cam stop mechanism 2 moves under the action of the motor. The cam 15 pushes the cam shaft 16, causing the moving plate 12 to move relative to the back plate 11 on the linear guide pair. The moving plate 12 moves downward, and at this time, a pair of fixed supports 13 and movable supports 131 lift the tray 6 at the descending transition station C and above to move downward. At the same time, the compression spring 22 pushes the scraper 21, and the scraper 21 pushes the second movable support 141 to continue to be in the retracted state. When the cam 15 descends to a certain height, the extension of the compression spring 22 reaches its maximum. Under the action of the compression spring 22, the second movable support 141 resets and supports the descending transition station. The discharge station falls on the moving unit below and the coating material is discharged.

[0088] like Figure 6 As shown, in this embodiment, the tray 6 is a square plate, and guide wheels 61 are provided at the four corners of the tray 6. Skirts are provided on the edges of the two symmetrical sides of the upper part of the tray 6. Hook holes 62 that cooperate with hooks are provided on the skirts. On the side of the tray 6 without skirts, slots are opened from the edge inward for the adjustment rod 53 to be inserted. The slots penetrate the upper and lower surfaces of the tray 6.

[0089] The purpose of the guide wheels 61 on the pallet 6 is to ensure that, during the rising and falling process within the rising and falling units, the guide wheels 61 can contact the inner wall of the equipment frame 3 to ensure the alignment of the pallet 6.

[0090] like Figure 2 and 5 As shown, in order to adjust the position of the paint adherent within the tray 6 during the descent process, a paint adherent position adjustment component 5 is also provided within the descent unit. In this embodiment, the paint adherent position adjustment component 5 preferably adopts an electric push rod drive mechanism, specifically: the paint adherent position adjustment component 5 includes a mounting frame 51, an electric push rod 52, and multiple adjustment rods 53. The mounting frame 51 is set on the equipment frame 3, the outer shell of the electric push rod 52 is set on the mounting frame 51, and the push rod end of the electric push rod 52 is connected to the adjustment rod 53 via a connecting plate 54. Magnets 55 are installed at the ends of the adjustment rods 53.

[0091] The working process of the paint adhesion position adjustment component 5 is as follows: extend the adjustment rod 53, use the magnet 55 at the end of the adjustment rod 53 to attract the paint adhesion, and extend the adjustment rod 53 into the slot on the tray 6 to adjust the position of the paint adhesion.

[0092] In this embodiment, at the discharge station, a belt conveyor is set up on the frame to transport the coating material away. The conveyor belt of the belt conveyor protrudes from the slot on the tray 6, lifts the tray 6, and drives the tray 6 to be sent out.

[0093] like Figure 1 and 2As shown, the driving component within the stacking and circulating feeding mechanism of this embodiment, in Figure 2 None of these are shown in the diagram. In this embodiment, the preferred drive components, such as a motor, sprocket drive mechanism, and belt conveyor, are all known technologies and are known to those skilled in the art.

[0094] The above embodiments are merely illustrative of the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solutions based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
