[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The embodiment of the present invention discloses a spray cleaning machine, see Figures 1 to 6 , which includes a frame 11, a conveying device 2, a spraying device 3 and a clamping device 4. The conveying device 2 includes a conveying power unit 21 and a conveying member 22. The conveying member 22 is driven by the conveying power unit 21 to convey from the feed port 51 to the discharge port 53 and is reciprocatingly mounted on the frame 11.

[0023] Continue to see Figure 1 and Figure 2 The conveying power unit 21 drives the conveying member 22 to reciprocate between the feed port 51 and the discharge port 53. When the feed port 51 → the discharge port 53 moves, the workpiece 6 is fed into the conveying member 22 from the feed port 51, cleaned by the spray device 3 on the cleaning channel 52, and then sent out from the discharge port 53, thereby forming continuous and uninterrupted cleaning. The loading and unloading of the workpiece 6 can be carried out without stopping the machine, thereby realizing continuous and uninterrupted cleaning and ensuring working efficiency.

[0024] Continue to see Figure 5 The spray device 3 includes a spray power unit 31 and a nozzle 32. The space between the feed port 51 and the discharge port 53 forms a cleaning channel 52. The nozzle 32 is configured to spray at least part of the absorbed spray liquid onto the surface of the workpiece 6 transported to the cleaning channel 52 under the drive of the spray power unit 31. The spray liquid is sprayed onto the surface of the workpiece 6 through the nozzle 32, so that the surface of the workpiece 6 is cleaned.

[0025] Continue to see Figure 1 , a cover 14 can be provided around the cleaning channel 52, and the cover 14 is fixed to the frame 11, so that the cleaning channel 52 is covered inside, and the nozzle 32 of the spray device 3 can also be covered inside. Thus, a space isolated from the outside (except for the feed port 51 and the discharge port 53) is formed inside the cleaning channel 52, and a flow channel is provided at the bottom of the cover 14 to flow into the filter 34. The filtered spray liquid can be reused by being pumped by the spray power unit 31, see Figure 5 , thereby completing the recycling of the circulating spray liquid.

[0026] Continue to see Figure 6The clamping device 4 includes a clamping power unit 41 and a clamping member 42. The clamping member 42 is located between the feed port 51 and the discharge port 53. The clamping member 42 is configured to clamp / release the workpiece 6 in the cleaning channel 52 under the drive of the clamping power unit 41. Through the setting of the clamping device 4, the position and posture of the workpiece 6 are relatively fixed during cleaning, and will not be greatly changed by the impact of the spray liquid jet from the nozzle, ensuring that the workpiece 6 can be transported from the feed port 51 to the discharge port 53 without falling, so that the spray liquid jet of the spray device 3 has the possibility of facing the workpiece 6, thereby improving the cleaning effect.

[0027] Continue to see Figure 3 and Figure 4 , the embodiment of the conveying power unit 21 may include a first motor 211, a first active pulley 212, a first conveying belt 213 and a first driven pulley 214 which are sequentially connected. The first motor 211 drives the first active pulley 212, the first conveying belt 213 and the second transmission pulley in sequence. The first conveying belt 213 will vibrate slightly in the working state, and the workpiece 6 placed thereon will vibrate slightly, which is conducive to the foreign matter, spray liquid, and the mixture of foreign matter and spray liquid attached to the workpiece 6 to separate from the workpiece 6, especially suitable for scenes with large adhesion, such as the workpiece 6 is various parts (such as shoes, etc.) made of light-cured resin by 3D printing, and the liquid resin attached to its surface has high viscosity and strong adhesion. The first conveying belt 213 is used for transportation so that the resin with strong adhesion can be separated.

[0028] Regarding the spray liquid, the spray power unit 31 (such as various medium pumps) can be connected to water (such as tap water), or to a specially configured container 33 (the container 33 contains a configured cleaning liquid, such as the cleaning liquid prepared by mixing water, ethanol, acetone, isopropanol, or propylene carbonate as disclosed in CN211683519U). Of course, considering the recycling, the spray liquid can be collected and filtered (such as using the filter 34 shown in the figure, especially the bag filter 34) after flowing down the cleaning channel 52, and then absorbed by the spray power unit 31, so as to complete the recycling.

[0029] Continue to see Figure 3 and Figure 4 The first active pulley 212 is arranged at one end of the discharge port 53, and the first driven pulley 214 is arranged at one end of the feed port 51. This arrangement makes the upper part of the first conveying belt 213 tensioned and the lower part relaxed, ensuring that the first conveying belt 213 will not jump significantly under the premise of slight shaking, thereby ensuring the normal transportation of the workpiece 6.

[0030] It should also be noted that the linear speed of the first conveying belt 213 should not be too large to ensure normal conveyance of the workpiece 6 .

[0031] Continue to see Figure 3 and Figure 4 There are multiple first conveyor belts 213, which are arranged at intervals in the transverse direction, so that foreign matter, spray liquid or a mixture of the two separated from the workpiece 6 can roll down along the gaps between the first conveyor belts 213, further improving the cleaning effect.

[0032] Continue to see Figure 3 and Figure 4 One embodiment of the first conveyor belt 213 is a round belt. The use of the round belt allows the first conveyor belt 213 to be twisted.

[0033] Continue to see Figure 2 and Figure 5 In order to further improve the cleaning effect, a plurality of nozzles 32 are arranged, including a top nozzle 321, a bottom nozzle 322, a left nozzle 323 and a right nozzle 324 located at the top, bottom, left and right of the cleaning channel 52, which can spray the spray liquid to the workpiece 6 from the top, bottom, left and right directions respectively, thereby improving the cleaning effect.

[0034] Continue to see Figure 5 The top nozzle 321 is laterally centered and is a 360° rotating nozzle 32 . The top nozzle 321 continuously or intermittently rotates to spray the spray liquid from top to bottom.

[0035] Continue to see Figure 5 The left nozzle 323 and the right nozzle 324 are arranged on both sides of the cleaning channel 52, one on the left and one on the right in the horizontal direction, and are at the same height as the workpiece 6 placed on the conveying member 22 in the vertical direction. The left nozzle 323 and the right nozzle 324 are rotating nozzles 32 that can swing back and forth within a range of no more than 180°. The left nozzle 323 and the right nozzle 324 spray cleaning liquid to the workpiece 6 from the left and right sides respectively, and clean the workpiece 6 from both sides. The swing range of the two nozzles 32 does not exceed 180°, and the middle position is perpendicular to the extension direction of the cleaning channel 52, ensuring that the two nozzles 32 only spray cleaning liquid into the cleaning channel 52, and do not spray cleaning liquid outside the cleaning channel 52.

[0036] Continue to see Figure 5 , the bottom nozzle 322 is centered laterally, and the bottom nozzle 322 is a 360° rotating nozzle 32. Through the continuous or intermittent rotation of the top nozzle 321, the spray liquid is sprayed from bottom to top.

[0037] The spray cleaning machine embodiment may further include a controller configured to automatically adjust the clamping degree according to at least one of the following parameters: The dimensions of the workpiece 6 to be clamped; The clamping force provided by the clamping member 42; Preset programs.

[0038] By automatically adjusting the clamping degree, the clamping degree is made moderate to avoid changes in the position and posture of the workpiece 6 due to insufficient clamping, and to avoid excessive clamping force on the workpiece 6 due to excessive clamping (which may cause dents in the workpiece 6, irreversible deformation, or even partial covering of the surface of the workpiece 6 by the clamping member 42, causing the covered area to be blocked and insufficiently cleaned. However, the use of the first conveyor belt 213 of the round belt mentioned above can greatly reduce the blocking effect).

[0039] The input quantity for automatic adjustment of the clamping degree may be at least one of the following: the dimension of the workpiece 6 to be clamped (such as the height of the shoe when the workpiece 6 is the shoe shown in the figure), the clamping force provided by the clamping member 42 (such as setting a force sensor, arranged between the clamping member 42 and the workpiece 6 or between the clamping member 42 and the clamping bracket 43, and dynamically adjusting by comparing the actual clamping force with a preset clamping force range in real time) and a preset program (such as by controlling the stroke of the clamping member 42).

[0040] In addition, the controller automatically adjusts the clamping degree according to the size of the workpiece 6 in the dimension to be clamped, wherein: Generate a clamping degree parameter (the bottom dead center to which the clamping member 42 moves after descending) based on the size of the dimension to be clamped (such as the height of the shoe as mentioned above); The clamping power unit 41 drives the clamping member 42 to clamp the workpiece 6 according to the clamping degree parameter, that is, the clamping member 42 stops moving after moving to the corresponding bottom dead point.

[0041] Each nozzle 32 may adopt a self-rotating structure, which has been widely used in industries such as greening irrigation, such as the self-rotating structures disclosed in CN117514167A, CN221386924U, CN220004478U and CN115846070A, etc.; it may also be a power-driven structure.

[0042] When the rotation of each nozzle 32 is driven by an additional power mechanism, see Figure 5The top nozzle 321 is driven by power, the first swing motor 3211 drives the outer shell of the rotary joint to rotate through the first swing belt 3212, and the three sub-spray heads are fixed to the outer shell of the rotary joint and the internal flow channels are connected to the internal flow channels of the rotary joint. The bottom nozzle 322 structure includes a second swing motor 3241 and a second swing belt 3242, which has the same structure and working principle as the top nozzle 321, and will not be described again. The left nozzle 323 has the same structure as the right nozzle 324. Taking the left nozzle 323 as an example, it includes a third swing motor 3221 and a rocker mechanism 3222. The rocker mechanism 3222 includes an eccentric rod 32221, a rocker arm 32222 and a swing arm 32223 hinged in sequence. The third swing motor 3221 drives the eccentric rod 32221, the rocker arm 32222 and the swing arm 32223 to rotate in sequence, thereby driving the corresponding outer shell of the rotary joint to rotate, thereby realizing swinging. The swing amplitude, starting position and ending position of the swing can be parameterized by the length of the eccentric rod 32221, the rocker arm and the swing arm 32223 and the rotation angle of the third swing motor 3221.

[0043] In particular, the power mechanism driving the left nozzle 322 and the right nozzle 323 can be connected to the controller signal, so as to achieve the above-mentioned width adjustment of the cleaning channel 52.

[0044] The inventors have found that when the spraying operation is not required (such as when a batch of workpieces 6 are cleaned, etc.), the width of the cleaning channel 52 is reduced to a size smaller than the corresponding dimension of the workpiece 6, thereby partially closing the cleaning channel 52 so that the stomach cleaning workpiece 6 is blocked at the feed port 51. This is a way to realize this concept. Figure 4 , the left and right sides of the cleaning channel 52 are respectively equipped with side baffles 12 by means of elastic members (not shown in the figure, which may be various springs) in a floating manner; the controller is also configured to automatically adjust the spray flow of the left nozzle 323 and the right nozzle 324 based on the width of the workpiece 6, and adjust the distance between the baffles 12 on both sides by means of compressing the elastic members. For example, if the width of the workpiece 6 is detected to be 15 cm, the lower limit of the width of the cleaning channel 52 may be set to be slightly larger than 15 cm, such as a range of 15.5 cm ± 0.3 cm, which can ensure the smooth passage of the workpiece 6, and the small gap between the workpiece 6 and the side baffle 12 can also play a limiting and guiding role to prevent the workpiece 6 from deflecting.

[0045] In order to prevent the side baffle 12 from blocking the cleaning liquid sprayed from the left nozzle 323 and the right nozzle 324, Figure 4A notch 121 is provided at the corresponding position of the side baffle plate and the left nozzle 322 and the right nozzle 323, so that the cleaning liquid can be sprayed onto the surface of the workpiece 6 through the notch 121 to ensure the cleaning effect. At the same time, in order to prevent the notch 121 from reducing or losing the guiding effect on the workpiece 6, a plurality of slender material blocking members 13 (such as ropes, etc.) are arranged at the notch 121, and the plurality of material blocking members 13 are kept at intervals, thereby providing space for the cleaning liquid jet to pass through.

[0046] In addition, the position to which the left nozzle 323 swings is mirror-symmetrical to the position to which the right nozzle 324 swings with respect to the longitudinal section of the cleaning channel 52. The spray liquid jets flowing out of the left nozzle 323 and the right nozzle 324 give the same impact to the workpiece 6, thereby offsetting each other laterally, so that the workpiece 6 can be firmly held on the conveying member 22, ensuring the cleaning effect.

[0047] A specific embodiment of the clamping member 42 is shown in FIG. Figure 6 , which includes a second motor 421, a second driving pulley 422, a second conveying belt 423, and a second driven pulley 424 which are sequentially connected and respectively installed on the clamping bracket 43. The second motor 421 drives the second driving pulley 422 to rotate, and drives the second driven pulley 424 to rotate through the second conveying belt 423. With the second conveying belt 423 on top and the first conveying belt 213 on the bottom, the workpiece 6 is pressed between the two. This pressing method ensures that the workpiece 6 is firmly pressed while not losing the above-mentioned "slight shaking", further improving the cleaning effect.

[0048] Of course, those skilled in the art will appreciate that the movement speed of the second conveyor belt 423 may be substantially the same as the movement speed of the first conveyor belt 213, thereby maintaining a stable clamping effect; or the movement speed of the second conveyor belt 423 may be slightly smaller than the movement speed of the first conveyor belt 213 (such as a ratio between the two of 0.98 and 0.95), thereby increasing the amplitude of the "slight shake" and allowing foreign matter, spray liquid, and a mixture of foreign matter and spray liquid attached to the workpiece 6 to be more thoroughly separated from the workpiece 6.

[0049] Continue to see Figure 6The second driving pulley 422 is arranged at one end of the discharge port 53, and the second driven pulley 424 is arranged at one end of the feed port 51. The second driving pulley 422 rotates from bottom to top, so that the second conveying belt 423 forms a tensioning side at the lower side and a loose side at the upper end, so that the lower side of the second conveying belt 423 in contact with the workpiece 6 is always kept in a tensioned state, avoiding the accumulation of elastic restoring force after bending and stacking, which is suddenly released under certain working conditions (such as vibration, etc.) and exerting a sudden friction force on the workpiece 6 (the friction force is very likely to drive the workpiece 6 to move at a speed different from that of the first conveying belt 213), thereby further ensuring the stable transportation of the workpiece 6 when it is clamped by the first conveying belt 213 and the second conveying belt 423.

[0050] Continue to see Figure 2 and Figure 6 There are multiple second conveyor belts 423, which are arranged in a transverse interval. The gaps between the second conveyor belts 423 facilitate the spray liquid of the top nozzle to pass through and spray onto the surface of the workpiece 6.

[0051] One implementation of the clamping power unit 41 is that it includes a push rod motor 411 and a clamping swing arm 412, wherein: The first end of the clamping swing arm 412 is hinged to the frame 11, and the second end of the clamping swing arm 412 is hinged to the clamping bracket 43; The push rod motor 411 drives the clamping swing arm 412 to rotate around the hinge axis at its first end, thereby driving the clamping swing arm 412 hinged at its second end to rotate.

[0052] There is at least one clamping swing arm 412 arranged on one of the left and right sides, and at least two on the other side. The clamping swing arm 412 is driven to rotate around the intersection axis of the second end of the clamping swing arm 412 by the extension and retraction of the push rod motor 411, thereby adjusting the distance between the clamping bracket 43 (the second conveying belt 423) and the first conveying belt 213, thereby adjusting the height of the conveying channel.

[0053] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included in the protection scope of the present invention.
