Description

TECHNICAL FIELD

[0001] The present application relates to a spraying processing device, in particular to an environmentally friendly active soil 3D printing spraying sheet processing device and method. BACKGROUND

[0002] The environmentally friendly active soil material itself is an environmentally friendly material mainly composed of natural active soil. It has excellent physical and chemical properties, such as good air permeability, adsorption and biocompatibility. This material not only has a wide source and low cost, but also does not pollute the environment during use, meeting the requirements of sustainable development of modern society. Through 3D printing technology, this active soil material can be accurately processed into a sheet with a certain thickness and shape to meet the needs of different application scenarios.

[0003] This sheet can be further processed according to needs, such as spraying processing. Spraying processing is a common surface treatment process, which aims to form a uniform coating on the surface of the sheet to improve its appearance, enhance its weather resistance, wear resistance or give it specific functional properties.

[0004] In the process of spraying the printed sheet, the currently widely used flow line spraying processing method has improved production efficiency to a certain extent, but has exposed a series of technical problems in actual operation.

[0005] Specifically, in the flow line spraying processing process, the sheet is placed on the conveyor belt, and the spraying nozzle reciprocally slides along the path perpendicular to the conveying direction. This operation method seems efficient, but in actual operation, due to the continuous movement of the conveyor belt, the sheet forms an oblique relationship between the vertical plane of the nozzle and the conveying process. This oblique relationship causes the relative position between the nozzle and the sheet to change constantly during spraying, and due to the slight delay between the reciprocating speed of the nozzle and the conveying speed of the sheet, the spraying area of the sheet may overlap or not be completely covered. This uneven spraying directly leads to the inconsistency of the spraying thickness on the surface of the sheet. SUMMARY

[0006] The purpose of the present application is to provide an environmentally friendly active soil 3D printing spraying sheet processing device and method to solve the problems raised in the background.

[0026] The method for using the environmental protection active soil 3D printing spraying sheet processing device comprises the following steps:

[0027] Step one: place the sheet to be sprayed on the chain, start the motor, and drive the chain gap conveying through the transmission belt, at this time the spraying head is in the shutdown state, and the sheet is waiting to enter the spraying range;

[0028] Step two: when the sheet is conveyed to the spraying range of the spraying head, the spraying head starts the spraying operation, at the same time, the spraying frame continuously sprays gas to form an air curtain for isolating the spraying area, preventing the spraying liquid from spreading, at this time, the motor continuously drives the reciprocating screw rod to rotate, so that the spraying head reciprocates on the transverse sliding frame in a direction perpendicular to the conveying direction of the chain, and the sheet is uniformly sprayed.

This design not only improves the uniformity of spraying, but also avoids the problems of repeated spraying or spraying omission caused by inaccurate sheet position.

[0034] In addition, a closing mechanism is also designed on the conveying and spraying structure. When the spraying head sprays the sheet, the spraying frame will continuously spray gas in a direction perpendicular to the sheet, forming an air curtain. This air curtain can effectively isolate the spraying area and prevent the flying spraying material from entering the sprayed or unsprayed area of the sheet. It avoids the problem of local over-thickness or under-thickness caused by the flying of the spraying material, thereby ensuring the spraying quality of the entire sheet. Through the conveying and spraying structure, uniform spraying of the sheet can be achieved, and the problems of repeated spraying or incomplete spraying can be avoided.

[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments.

[0051] Please refer to Figures 1-6 In the embodiments of the present application, an environmental-friendly active soil 3D printing and spraying sheet processing device comprises a main body 1, a conveying and spraying structure is arranged on the main body 1, and the conveying and spraying structure comprises:

[0053] A sliding spraying member is mounted on the main body 1, and a power source for driving a spraying head 10 on the sliding spraying member to perform a reciprocating sliding action is mounted on the sliding spraying member;

[0054] The power source is connected with a large transmission wheel 13 rotatably arranged on the main body 1, the large transmission wheel 13 is connected with a linkage gear 17 fixed on one of the transmission members through a transmission belt 12, and can intermittently drive the linkage gear 17 to perform a rotating action, so that the chain 5 can convey the sheet, and the conveying action of the chain 5 is synchronized in time with the reciprocating action of the spraying head 10 when the spraying head 10 moves to one end on the sliding spraying member.

[0055] In this embodiment, the main body 1 serves as the core frame of the entire device, providing a stable support foundation for the conveying and spraying structure, the two conveying frames 2 are symmetrically fixed on the main body 1, and a plurality of transmission members are arranged on the conveying frames 2, ensuring that the chain 5 can stably and accurately run during the conveying process, the chain 5 as a key component for carrying and conveying the sheet, the design of the transmission connection ensures that the sheet can always maintain a stable position during the conveying process, providing reliable protection for the subsequent spraying operation.

[0056] The sliding spraying member is mounted on the main body 1, and the spraying head 10 equipped on the sliding spraying member is the core component for realizing the spraying function, the power source provides necessary power support for the reciprocating sliding action of the spraying head 10, ensuring that the spraying head 10 can uniformly spray along the direction perpendicular to the conveying direction of the chain 5 on the sliding spraying member, this design not only improves the spraying efficiency, but also avoids the problems of overlapping or non-coverage in the traditional spraying mode through the precise control mechanism, thereby ensuring the uniformity of the spraying thickness.

[0057] The connection of the power source and the large transmission wheel 13, and the cooperation of the large transmission wheel 13 and the linkage gear 17 through the transmission belt 12, the design makes the conveying action of the chain 5 and the reciprocating action of the spraying head 10 can be accurately synchronized in time, when the spraying head 10 moves to one end of the sliding spraying part and is ready to reciprocate, the large transmission wheel 13 drives the linkage gear 17 to rotate through the transmission belt 12, and then drives the chain 5 to convey the sheet, the synchronization mechanism ensures that the sheet is always in the best spraying position of the next spraying area during the spraying process, so that the high-quality spraying effect is realized.

[0058] Please refer to Figure 7 and Figure 9 As a further scheme of the present application, the transmission member comprises a transmission shaft 3 rotating between the two conveying frames 2 and a plurality of drive gears 4 fixed on the transmission shaft 3.

[0059] The drive gears 4 are in transmission connection with the chain 5, and the chain 5 is driven to convey the sheet by the rotation of the drive gears 4.

[0060] In this embodiment, the transmission member mainly comprises a transmission shaft 3 and a plurality of drive gears 4 fixed thereon, the transmission shaft 3 is installed between the two conveying frames 2 and can rotate freely, thereby providing stable rotary support for the drive gears 4, the drive gears 4 are in transmission connection with the chain 5, when the drive gears 4 rotate, the toothed structure thereof meshes with the links of the chain 5, thereby driving the chain 5 to move stably along the predetermined path, and this transmission mode ensures that the movement of the chain 5 has high stability and accuracy.

[0061] Please refer to Figure 7 and Figure 8 As a further scheme of the present application, the sliding spraying part comprises a transverse moving frame 6 fixed on the main body 1 and a lifting frame 9 sliding on the transverse moving frame 6.

[0062] The lifting frame 9 is installed with a spraying head 10, the lifting frame 9 is connected with a reciprocating lead screw 7 rotatably connected on the transverse moving frame 6, and the reciprocating lead screw 7 is connected with a power source, and the reciprocating sliding of the spraying head 10 on the transverse moving frame 6 is realized by the rotation of the reciprocating lead screw 7.

[0063] In this embodiment, the lifting frame 9 is installed with a spraying head 10, which is responsible for uniformly spraying the spraying material to the surface of the sheet, in order to realize the accurate movement of the spraying head 10, the lifting frame 9 is connected with a reciprocating lead screw 7 on the transverse moving frame 6, the reciprocating lead screw 7 is connected with a pin head on the lifting frame 9, when the reciprocating lead screw 7 rotates, the lifting frame 9 can reciprocate along the direction of the transverse moving frame 6, and this design ensures that the spraying head 10 can uniformly spray on the surface of the sheet.

[0064] The power source of the reciprocating screw rod 7 is a power source connected thereto, which drives the reciprocating screw rod 7 to rotate, so that the spraying head 10 can realize accurate reciprocating sliding on the transverse frame 6, thereby realizing uniform spraying on the surface of the sheet.

[0065] Please refer to Figures 8-10 As a further scheme of the present application, the power source comprises a motor 8 mounted at one end of the transverse frame 6 and a small transmission wheel 11 fixed on the output shaft of the motor 8.

[0066] The small transmission wheel 11 is fixedly connected to one end of the reciprocating screw rod 7, and the small transmission wheel 11 is in transmission connection with the transmission belt 12, so that the reciprocating sliding action of the spraying head 10 is realized through the driving of the motor 8.

[0067] In this embodiment, the small transmission wheel 11 is fixedly connected to one end of the reciprocating screw rod 7, which ensures that the power of the motor 8 can be efficiently transmitted to the reciprocating screw rod 7. When the motor 8 is started, the output shaft drives the small transmission wheel 11 to rotate, and the rotation of the small transmission wheel 11 further drives the reciprocating screw rod 7 to rotate. The reciprocating screw rod 7 is connected to the pin head on the lifting frame 9, so that the lifting frame 9 can reciprocate along the direction of the transverse frame 6.

[0068] In addition, the small transmission wheel 11 is also in transmission connection with the large transmission wheel 13 through the transmission belt 12. This design makes the power of the motor 8 not only drive the reciprocating sliding of the spraying head 10, but also realize the intermittent driving control of the conveying chain 5 through the transmission of the transmission belt 12 and the large transmission wheel 13. Through the transmission ratio design of the small transmission wheel 11 and the large transmission wheel 13, the small transmission wheel 11 rotates for multiple turns to drive the large transmission wheel 13 to rotate one turn. When the spraying head 10 moves to one end of the transverse frame 6 and is ready to perform reciprocating action, the large transmission wheel 13 drives the linkage gear 17 to rotate through the transmission belt 12, thereby driving the chain 5 to convey the sheet. This synchronous mechanism ensures that the sheet is always in the best spraying position during spraying, thereby avoiding problems such as uneven spraying, overlapping or omission.

[0069] Please refer to Figures 9-12 As a further scheme of the present application, the large transmission wheel 13 is in transmission connection with the transmission belt 12, one side of the large transmission wheel 13 is fixedly connected with a limiting disc 14, and the outer wall of the limiting disc 14 is fixedly connected with a tooth groove 15 for cooperating with the linkage gear 17 to realize intermittent driving.

[0070] One side of the linkage gear 17 is fixedly connected with an abutting disc 16, and a plurality of arc-shaped edges abutting the edge of the limiting disc 14 are arranged in an annular array on the abutting disc 16. Through the cooperation of the abutting disc 16 and the limiting disc 14, the intermittent rotation of the linkage gear 17 is realized.

[0071] In this embodiment, the large transmission wheel 13 is fixed with a limiting disc 14 on one side, and the outer wall of the limiting disc 14 is provided with tooth grooves 15, which are in mesh with the linkage gear 17, so as to realize the intermittent conveying function of the chain 5. Through the accurate control of the conveying action of the chain 5, it is ensured that the spraying head 10 can accurately aim at the predetermined position of the sheet material during each spraying.

[0072] The linkage gear 17 is fixed with a resisting disc 16 on one side, and the resisting disc 16 is provided with a plurality of arc edges in an annular array, which are closely fitted with the edges of the limiting disc 14. The limiting disc 14 is provided with a notch at the position of the tooth groove 15, which is matched with the rotating path of the resisting disc 16. When the large transmission wheel 13 rotates, the arc edges on the resisting disc 16 are fitted with the circular outer wall of the limiting disc 14, so as to limit the rotation of the resisting disc 16. When the limiting disc 14 rotates to the position where the tooth groove 15 on the limiting disc 14 is in mesh with the linkage gear 17, the tooth groove 15 can mesh to make the linkage gear 17 rotate. Since the linkage gear 17 is fixed with the resisting disc 16, it can drive the resisting disc 16 to rotate synchronously. At this time, the rotating path of the resisting disc 16 is located at the notch position of the limiting disc 14, and does not affect the rotation of the resisting disc 16. Therefore, when the limiting disc 14 rotates one circle, the linkage gear 17 can realize intermittent rotation. The intermittent rotation is transmitted to the chain 5 through the transmission member, so as to control the intermittent conveying of the chain 5, and ensure that the sheet material always maintains the correct spraying position during the spraying process. The rotating action of the linkage gear 17 coincides with the time when the spraying head 10 moves to one end on the transverse moving frame 6 and is ready to perform the reciprocating action. When the spraying head 10 completes the reciprocating action and sprays, the chain 5 is in a static state, the action of conveying and supplying the sheet material is completed, and the spraying head 10 can spray the un-sprayed area of the sheet material.

[0073] Please refer to Figure 6 , Figure 13 and Figure 14 , as a further scheme of the present application, the conveying frame 2 is symmetrically provided with an opening and closing mechanism, which performs rapid closing and separating operation when the chain 5 conveys.

[0074] The opening and closing mechanism comprises a sliding frame 18 fixed on the conveying frame 2, a sliding frame 20 sliding on the sliding frame 18, a spraying and collecting member fixed on the sliding frame 20, and a closing member connected with the sliding frame 20.

[0075] The spraying and collecting member comprises a closing and collecting frame 19 connected with the sliding frame 20, and a spraying frame 21 provided on one side of the closing and collecting frame 19.

[0076] The closed collection frame 19 is provided with a guide slope for guiding the sprayed liquid, and the bottom of the guide slope is provided with a discharge valve for discharging the collected liquid.

[0077] The blowing frame 21 continuously blows gas in a direction perpendicular to the ground to form a gas curtain for isolating the spraying area during spraying.

[0078] The closing part includes a push-pull electromagnet 22 mounted on the conveying frame 2, and the telescopic end of the push-pull electromagnet 22 is fixedly connected with the sliding frame 20, so that the sliding frame 20 can be quickly closed and separated through the telescopic action of the push-pull electromagnet 22.

[0079] The two ends of the transverse frame 6 are provided with micro switches that abut against the lifting frame 9, and the micro switches are electrically connected with the push-pull electromagnet 22.

[0080] In this embodiment, the design of the opening and closing mechanism includes multiple components that work together. The sliding frame 18 is fixed on the conveying frame 2, providing a stable support structure for the entire mechanism. The sliding frame 20 can slide freely within the sliding frame 18, and the blowing and collecting part is mounted on the sliding frame 20, which plays a crucial role in liquid management and area isolation during spraying. The blowing and collecting part consists of a closed collection frame 19 and a blowing frame 21. The closed collection frame 19 is designed with a guide slope to guide the excess liquid generated during spraying to the discharge valve at the bottom, thereby achieving effective collection and discharge of the liquid, preventing the accumulation and overflow of the liquid in the spraying area, and maintaining the cleanliness of the spraying environment.

[0081] The blowing frame 21 is connected with the gas delivery equipment outside, responsible for forming a gas curtain perpendicular to the ground during spraying. This gas curtain not only effectively isolates the spraying area, preventing the sprayed liquid from spreading to the non-spraying area on the sheet, but also protects the operator from potential harm from the sprayed liquid to some extent, while also helping to maintain the stability of the spraying environment, ensuring the uniformity and consistency of the spraying quality.

[0082] The design of the closing part provides power support for the quick action of the opening and closing mechanism. The push-pull electromagnet 22 is installed on the conveying frame 2, and its telescopic end is fixedly connected with the sliding frame 20. When the lifting frame 9 carrying the spraying head 10 is moved to one end of the transverse frame 6, the lifting frame 9 will abut against the micro switch at one end of the transverse frame 6. The push-pull electromagnet 22 is activated through the micro switch, and through precise control of the telescopic action of the push-pull electromagnet 22, the sliding frame 20 can be quickly closed. The push-pull electromagnet 22 is an application of existing technology.

[0083] When the spraying head 10 moves back and forth, the lifting frame 9 is disengaged from the micro switch, at this time the push-pull electromagnet 22 is actuated, so that the collection frame 19 is quickly separated, so that in the process of the chain 5 conveying the sheet, the closing and releasing of the collection frame 19 is accurately controlled, so that when the spraying head 10 moves to one side of the sheet, the closed collection frame 19 can prevent the liquid sprayed on the spraying head 10 from falling on the sheet, avoiding causing the local of the sheet to be repeatedly sprayed and covered, improving the spraying effect, when the collection frame 19 is closed, the sprayed liquid will fall on the flow guide slope arranged on the collection frame 19 for collection, avoiding the waste of spraying material.

[0084] The method for using the environment-friendly active soil 3D printing spraying sheet processing device as described above comprises the following steps:

[0085] Step one: place the sheet to be sprayed on the chain 5, start the motor 8, and drive the chain 5 to convey intermittently through the transmission belt 12, at this time the spraying head 10 is in a stopped state, waiting for the sheet to enter the spraying range;

[0086] Step two: when the sheet is conveyed to the spraying range of the spraying head 10, the spraying head 10 starts the spraying operation, at the same time, the blowing frame 21 continuously blows gas to form a gas curtain to isolate the spraying area, preventing the spraying liquid from spreading, at this time, the motor 8 continuously acts to drive the reciprocating lead screw 7 to rotate, so that the spraying head 10 slides back and forth on the transverse sliding frame 6 perpendicular to the conveying direction of the chain 5, to uniformly spray the sheet;

[0087] Step three: when the spraying head 10 moves to one end on the transverse sliding frame 6 and is ready to move back and forth, the large transmission wheel 13 drives the linkage gear 17 to rotate through the transmission belt 12, so that the sheet on the chain 5 is conveyed for a distance, and the back-and-forth movement of the spraying head 10 is accurately synchronized in time with the conveying movement of the sheet;

[0088] Step four: when the chain 5 is in action, the closed collection frame 19 quickly performs the closing and opening actions under the control of the push-pull electromagnet 22, when the closed collection frame 19 is closed, the excess liquid sprayed by the spraying head 10 is collected and guided to the discharge valve through the flow guide slope for discharge, preventing the liquid from overflowing;

[0089] Step five: when the spraying head 10 moves back and forth on the transverse sliding frame 6, the closed collection frame 19 is in an open state, the spraying head 10 continuously sprays the sheet until the spraying of the whole sheet is completed.

[0090] The above embodiments are exemplary and not limiting, and the technical solutions of the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application.

10. A method for processing environmentally friendly activated clay 3D printing spray-coated sheets using any one of claims 1-9, characterized in that, Includes the following steps: Step 1: Place the sheet to be sprayed on the chain (5), start the motor (8), and drive the chain (5) intermittently through the transmission belt (12). At this time, the spray head (10) is in a stopped state, waiting for the sheet to enter the spraying range. Step 2: When the sheet material is conveyed to the spraying range of the spray head (10), the spray head (10) starts the spraying operation. At the same time, the spray frame (21) continuously sprays gas to form an air curtain that isolates the spraying area and prevents the spraying liquid from spreading. At this time, the motor (8) continues to drive the reciprocating screw (7) to rotate, so that the spray head (10) slides back and forth on the transverse frame (6) in a direction perpendicular to the conveying direction of the chain (5) to spray the sheet material evenly. Step 3: When the spray head (10) moves to one end on the transverse frame (6) and is ready to reciprocate, the large transmission wheel (13) drives the linkage gear (17) to rotate through the transmission belt (12), so that the sheet on the chain (5) is transported a distance. The reciprocating motion of the spray head (10) and the conveying motion of the sheet are precisely synchronized in time. Step 4: When the chain (5) moves, the closed collection box (19) quickly performs the closing and opening actions under the control of the push-pull electromagnet (22). When the closed collection box (19) closes, the excess liquid sprayed by the spray head (10) is collected and guided to the discharge valve through the guide slope to prevent liquid overflow. Step 5: When the spray head (10) moves back and forth on the transverse frame (6), the closed collection frame (19) is in the open state, and the spray head (10) continues to spray the sheet until the entire sheet is sprayed.
