Description

Technical Field

[0001] The present application relates to the technical field of profile surface processing, and in particular to a batching device. Background Art

[0002] Aluminum profiles have excellent properties, such as low density, strong corrosion resistance, good ductility, strong plasticity, good thermal conductivity / electrical conductivity, good surface treatment performance, etc., so they are widely used in many industries, such as: transportation industry (automobile manufacturing, rail transportation industry), equipment and machinery manufacturing industry, durable consumer goods industry, photovoltaic power generation industry, etc. Among them, when the profile is applied to the photovoltaic power generation industry, the surface of the photovoltaic profile is usually sandblasted and meets the appearance requirements, for example: the sandblasting needs to be uniform to meet the uniformity requirements of the profile surface color after sandblasting. In the process of sandblasting the photovoltaic profile, as the number of sand grains circulation increases, the color of the profile surface will change. If the color difference is too large, the appearance requirements of the photovoltaic profile cannot be met. In order to avoid this situation, the existing technology usually adjusts the sandblasting parameters to appropriately reduce the color difference, but the method of adjusting the sandblasting parameters is unstable or incompatible with the sand grains. Therefore, the color of the profile surface after sandblasting still cannot guarantee its uniformity, that is, the sandblasting effect is not ideal. Summary of the invention

[0003] During the sandblasting process of the profile, the surface color of the profile will change, resulting in color difference. The inventor found that this is related to the fact that during the sandblasting process, as the number of sand particles circulation increases, the sand particles are worn or broken, so the size of the sand particles becomes smaller, which causes the ratio of coarse sand to fine sand to change, resulting in color difference on the surface of the aluminum profile after sandblasting. Since the coarse and fine ratio of the sand particles cannot be accurately obtained during the sandblasting process, the sandblasting parameters cannot be accurately adjusted to adapt to the ratio change, and the color difference problem of the profile surface cannot be solved. In order to solve this color difference problem, the inventor has conducted in-depth research and developed a batching device that can classify sand materials according to different particle sizes and mix the sand particles in proportion according to actual needs. During the sandblasting process, mixed sand with a basically consistent coarse and fine ratio of sand particles can be circulated, and thus, the problem of profile surface color difference can be solved without adjusting the sandblasting parameters. The detailed description is as follows.

[0070] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0071] The following is a specific embodiment and combined with the attached Figure 1-Figure 15 The present application is described in further detail.

[0072] The batching device provided in the embodiment of the present application is connected to a sandblasting system when in use, such as Figure 1 , Figure 3 , Figure 6As shown, the batching device includes: a base 100, a screen box 200, a material guide trough 300 and a mixing chamber 500; wherein, at least two screen boxes 200 are provided, both are pivotally connected to the base 100 and are distributed at intervals along the diagonal direction; the material guide trough 300 is obliquely arranged between two adjacent screen boxes 200, and is configured to receive the material from the screen box 200 obliquely above it and introduce it into the screen box 200 obliquely below it, and independent storage boxes 400 are provided below the material guide trough 300 and the screen box 200, and the discharge port of each storage box 400 is provided with a control valve 410, and is connected to the mixing chamber 500.

[0073] The oblique direction in this embodiment refers to a certain inclination angle relative to the vertical direction; the aperture sizes of the sieve holes 230 of each sieve box 200 are different, and the apertures of the sieve holes of each sieve box 200 increase or decrease in sequence. For example, along the oblique direction, the sieve holes 230 increase or decrease in sequence, the sieve holes of the sieve box at the highest position are the largest, and the sieve holes of the sieve box at the lowest position are the smallest, or the sieve holes of the sieve box at the highest position are the smallest, and the sieve holes of the sieve box at the lowest position are the largest. In addition, Fig.15 As shown, the inner diameter of the mesh 230 is smaller than the outer diameter to avoid clogging of the mesh.

[0074] The batching device provided in the embodiment of the present application is used to configure materials according to requirements of different particle size ratios, for example, to configure the sand required for sandblasting of photovoltaic profiles. Specifically, taking two screen boxes 200 as an example, the screen hole diameter of the high screen box 200 is smaller than the screen hole diameter of the low screen box 200. For ease of understanding, the screen box 200 located at the high position is named the first screen box, and the screen box 200 located at the low position is named the second screen box. When the batching device is used, the first screen box screens the sand therein, and the sand with smaller particles falls directly into the storage box 400 below the first screen box. The remaining sand in the first screen box is poured into the guide trough 300 through the rotation of the first screen box, and is introduced into the second screen box A secondary screening is performed, and the sand material leaking out from the screen holes of the second screen box directly falls into the storage box 400 below the second screen box, and the remaining sand material in the second screen box is directly introduced into the storage box 400 below the guide trough 300 through the rotation and tilting of the second screen box. For ease of understanding, the storage box below the first screen box is named the first storage box, the storage box below the second screen box is named the second storage box, and the storage box below the guide trough 300 is named the third storage box. It can be seen that the sand material is divided into three types of sand materials with different particle sizes after screening by the first screen box and the second screen box, namely, fine-grained sand falling into the first storage box, medium-grained sand (with a medium particle size) falling into the second storage box, and coarse-grained sand falling into the third storage box.

[0075] In the batching device provided in the embodiment of the present application, each screen box is arranged at an oblique interval and connected by a material guide trough in the middle, and a material storage box is arranged below the material guide trough and the screen box. Each screen box 200 can be rotated and tilted relative to the base 100. The structure of the entire device is compact, which can make full use of the three-dimensional space and save floor space.

[0076] In the batching device of the embodiment of the present application, Figure 1 As shown, the bottom surface of the mixing chamber is inclined, and the inlet connected to the outlet of each storage box or the control valve is higher than the outlet, so that the mixed material can be discharged smoothly. In this embodiment, the mixing chamber is configured as a tubular structure and is inclined to facilitate the mixing of sand and material and the smooth discharge out of the cavity, so as to perform sand blasting on the surface of the profile.

[0077] In the batching device of the embodiment of the present application, Figure 1 As shown, the discharge port of each storage box 400 is provided with a control valve 410, and is connected to the mixing chamber 500. Each control valve 410 can be controlled individually, and thus the outflow of sand in each storage box 400 can be accurately controlled, and then the ratio of coarse, medium and fine sand required for sandblasting can be accurately and stably adjusted according to the requirements of the sand particle size ratio, so as to further improve the uniformity of sandblasting and reduce the color difference of profile sandblasting; when the batching device is connected / connected to the sandblasting system, the sand in the sandblasting process can be cyclically introduced into the screen box to accurately screen the sand particles, and the screened sand can be introduced into the corresponding storage box, and then the sand output of each storage box can be accurately controlled by the control valve, so as to accurately control the ratio of coarse, medium and fine sand, and realize a uniform and accurate proportion of mixed sand for sandblasting process, so that the color uniformity of the profile surface can be ensured by the sandblasting process without adjusting the sandblasting parameters.

[0078] In the batching device of the embodiment of the present application, Figure 1 , Figure 3 , Figure 6 As shown, a receiving tray 600 is provided between the screen box 200 and the storage box 400 below it. The receiving tray 600 is pivotally connected to the base 100 and can be rotated to a first position and a second position; the receiving tray 600 is configured as follows: if it is located in the first position, the receiving tray 600 is located directly below the screen box 200 and is tilted to receive the material from the screen box 200 above it and introduce it into the material guide trough 300; if it is located in the second position, the receiving tray 600 is located below the edge of the screen box 200 above it, so that the storage box 400 can directly receive the material from the screen box 200.

[0079] Specifically, one end of the receiving tray 600 close to the material guide trough 300 is pivotally connected to the base 100, and the base 100 is fixed with a limit block 610, which is located obliquely above the material guide trough 300; when the receiving tray 600 is in the first position, one end of the receiving tray 600 close to the material guide trough 300 is located directly above the upper end of the material guide trough 300, and one end away from the material guide trough 300 overlaps the limit block 610. At this time, the surface of the receiving tray 600 for receiving the sand material is an inclined surface, so that the receiving tray 600 can be tilted. It is convenient to smoothly guide the sand material it receives into the guide trough 300; for ease of understanding, the end of the receiving plate 600 close to the guide trough 300 is the proximal end, and the end away from the guide trough 300 is the distal end. When the receiving plate 600 is in the second position, the distal end of the receiving plate 600 can rotate around the proximal end relative to the base 100, for example, flip upward, and after flipping to the second position, it can be separated from the area directly below the first screen box, so that the sand material in the first screen box falls directly into the first storage box. It should be noted that, although not shown in the figure, a limiting protrusion for limiting the second position can also be provided, and the limiting protrusion can be fixed on the base 100, for example, the limiting protrusion is located at a position above the upper end of the guide trough 300, or the limiting protrusion is provided at the upper end of the guide trough 300, which is not limited here, as long as the receiving plate 600 can be flipped within a preset angle range.

[0080] It should be noted that, in addition to being set as a flip structure, the material receiving tray 600 can also be set as a movable structure, that is, the material receiving tray is set to be telescopic relative to the material guide trough 300. For example, the material receiving tray 600 is slidably connected to the upper end of the material guide trough 300, which can also realize the function of the material receiving tray 600. The material receiving tray 600 can also be used as a part of the material guide trough 300, that is, the purpose of the material receiving tray 600 receiving the material is to guide it into the material guide trough 300, that is, the material receiving tray 600 also has the function of guiding the material. In this case, the material guide trough 300 has a fixed part that is immovable relative to the base 100 and a movable part that is movable (rotatable or movable) relative to the base 100. The movable part is the material receiving tray 600 structure at the upper end of the material guide trough 300.

[0081] In this embodiment, the setting of the receiving tray 600 can make the selection of the screen box more flexible. For example, when the fine-pore screen box needs to be set at a high place, the receiving tray 600 is located at the second position during screening. When the coarse-pore screen box needs to be set at a high place, the receiving tray 600 is located at the first position during screening. In addition, it can also be arranged that the sieve holes of the first screen box are larger than the sieve holes of the second screen box, that is, when the coarse-hole screen box is located at a high place, when screening sand particles, the receiving plate 600 below the first screen box is located at the first position, and the sand material leaking through the sieve holes of the first screen box directly falls into the material guide trough 300 and is guided to the second screen box, and then the receiving plate 600 is located at the second position, and the sand material remaining after screening by the first screen box is coarse-grained sand, which is directly poured into the first storage box after the first screen box is rotated and tilted. Similarly, the sand material leaking through the sieve holes of the second screen box can be directly dropped into the second storage box as fine-grained sand, and the sand material remaining after screening by the second screen box can be directly poured into the third storage box as medium-grained sand after the second screen box is rotated and tilted.

[0082] In the batching device of the embodiment of the present application, Figure 1-Figure 4 As shown, it also includes a flip assembly 700, such as Figure 8 , Fig.10 As shown, the flip assembly 700 includes a first pivot shaft 710, a connecting rod 720 and a linear drive member 730; the screen box 200 is pivotally connected to the base 100 through the first pivot shaft 710; the lower end of the connecting rod 720 is pivotally connected to the base 100, and the upper end is connected to the positioning part of the screen box 200, and the positioning part is spaced apart from the first pivot shaft; the body of the linear drive member 730 is installed on the base 100, and its power output end is pivotally connected to the middle part of the connecting rod 720.

[0083] In this embodiment, taking the example of setting the first pivot shaft 710 at the upper part of the guide trough 300, the first pivot shaft 710 is located at the edge of one side of the upper end of the screen box 200, and the positioning portion is located at the edge of the other side of the lower end of the screen box 200. It can be understood that the first pivot shaft 710 and the positioning portion are located in the diagonal area of ​​the screen box 200. Such a setting can maximize the rotational force arm as much as possible; the linear drive member 730 can be a linear electric cylinder, a hydraulic cylinder or a pneumatic cylinder, etc., to achieve linear reciprocating motion. The power output end of the linear drive member 730 drives the connecting rod 720, and the connecting rod 720 rotates / sways around its lower end, so that the upper end of the connecting rod 720 drives the screen box The positioning portion of 200 rotates around the axis of the first pivot shaft 710 to tilt the corresponding screen box 200 and pour the sand material therein into the receiving tray 600 or the corresponding storage box thereunder; for example, taking the first screen box as an example, when the screen holes of the first screen box are fine holes, the fine sand falls directly into the first storage box after screening before it is tilted over, and the remaining sand material is directly tilted over and poured into the receiving tray 600, and introduced into the material guide trough 300 for secondary screening; when the screen holes of the first screen box are coarse holes, the sand material that needs to be screened for the second time before it is tilted over falls directly into the receiving tray 600, and is introduced into the material guide trough 300 for secondary screening, and the remaining coarse sand material is directly poured into the first storage box after it is tilted over. It can be seen from this that the setting of the flipping assembly 700 can enable the screen box 200 to rotate and tilt as needed. During this process, on the one hand, the loading, screening and unloading of the screen box can be achieved by flipping the screen box, and the operation is flexible and convenient; on the other hand, during the flipping process, its activity space is mainly the surrounding area of ​​the screen box 200, which occupies less space and can make full use of the three-dimensional space, thereby saving the space occupied by the horizontal plane.

[0084] Specifically, in the present embodiment, the free end of the connecting rod 720 can be set as a hook-shaped structure with its opening facing upward; the positioning portion of the screen box 200 is located at the corner portion of the lower end portion of the screen box 200, and a positioning block 210 is fixed to this portion. A slot is provided between the positioning block 210 and the side wall of the screen box 200, and the slot can be matched with the hook-shaped opening of the connecting rod 720. The screen box 200 can be overlapped on the hook-shaped structure of the connecting rod 710 through the positioning block 210, thereby realizing the driving and flipping of the screen box 200 by the connecting rod 720.

[0085] In the batching device of the embodiment of the present application, Figure 3 , Figure 4 , Figure 7 , Figure 8 , Fig.12As shown, the flip assembly 700 also includes two coaxially arranged first swing arms 740 and two coaxially arranged second swing arms 750; one end of the first swing arm 740 is pivotally connected to the base 100 through the first pivot shaft 710, and the other end is rotatably connected to the edge of one side of the upper end of the screen box 200; one end of the second swing arm 750 is pivotally connected to the base 100 through the second pivot shaft 760, and the other end is rotatably connected to the first vibration assembly 800, and the first vibration assembly 800 is connected to the edge of the other side of the upper end of the screen box 200. In this way, during the tilting process of the screen box 200, the activity area of ​​the screen box 200 can be flexibly increased by swinging the corresponding swing arm, and the screen box is conveniently connected to or separated from the first vibration assembly (overlapped on the vibration rod, see the subsequent detailed description); at the same time, the arrangement of the first swing arm 740 and the second swing arm 750 can realize the horizontal swing of the screen box 200, and then the sand material therein can be vibrated in the horizontal swing direction.

[0086] Specifically, Figure 7 As shown, the two coaxially arranged first swing arms 740 are both rotatably connected to the edge of one side of the upper end of the screen box 200 through the support rod 770, which can ensure the connection strength and connection accuracy between the two and the screen box 200; the specific connection method can be that the support rod 770 and the first swing arm 740 are rotatably connected through a bearing, and the support rod 770 and the screen box 200 can also be rotatably connected through a bearing.

[0087] In the batching device of the embodiment of the present application, the connection part between the first swing arm 740 and the first pivot shaft 710, the connection part between the first swing arm 740 and the screen box 200, the connection part between the second swing arm 750 and the screen box 200, and the connection part between the second swing arm 750 and the second pivot shaft 760, the four connection parts form a parallelogram, so that the screen box 200 can always remain horizontal during the horizontal swinging process. The second swing arm 750 is connected to a swing motor (not shown in the figure) to drive the second swing arm 750 to swing around the second pivot shaft 760. The body of the swing motor is fixedly installed on the base 100, and its power output end is fixedly connected to the second swing arm 750 to drive the second swing arm 750 to swing around the second pivot shaft 760, thereby synchronously driving the first swing arm 740 to swing, so as to realize the horizontal swinging of the screen box 200, and the swinging amplitude is determined by the swing arm size and the swinging angle. The horizontal swinging can be regarded as the vibration of the screen box in the horizontal direction.

[0088] In the batching device of the embodiment of the present application, Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig.12As shown, the first vibration component 800 includes a vibration rod 810 and a vibration motor (not shown in the figure) for driving the vibration rod 810 to rotate; the vibration rod 810 is pivotally connected to the second swing arm 750, and the vibration rod 810 has a vibration protrusion 820 protruding from its outer peripheral surface, and the screen box 200 is overlapped on the portion of the vibration rod 810 having the vibration protrusion 820, that is, the screen box 200 is connected to the second swing arm 750 through the vibration rod 810. The vibration rod 810 rotates under the drive of the vibration motor, thereby driving the vibration protrusion 820 to rotate around the axis of the vibration rod 810, which is equivalent to the vibration rod 810 and the vibration protrusion 820 thereon forming a non-smooth transition cam structure. When the vibration protrusion 820 rotates to the overlapping part of the screen box 200, the overlapping part of the screen box 200 will be quickly lifted. As the vibration protrusion 820 continues to rotate, the overlapping part of the screen box 200 will then be rapidly lowered. The difference in lift and lowering is the height dimension of the vibration protrusion 820 protruding from the vibration rod 810, so as to achieve the up and down vibration of the screen box 200. A bearing can be set between the vibration rod 810 and the second swing arm 750 to achieve a rotational connection. In this embodiment, a plurality of vibration protrusions 820 can be set, and they are set at circumferential intervals around the vibration rod 810. They can be evenly set or unevenly set, which is not limited here.

[0089] It should be noted that, in this embodiment, the first swing arm 740 and the second swing arm 750 have almost the same structure, the spacing between the first pivot axis 710 and the second pivot axis 760 is the first spacing, and the spacing between the support rod 770 and the vibration rod 810 is the second spacing. When the first spacing and the second spacing are equal, the first swing arm and the second swing arm are exactly two relatively parallel sides of a parallelogram, so that the screen box 200 can always remain horizontal during the horizontal swinging process. The screen box 200 has a lap joint 220, which is arranged at the upper end of the screen box 200. The lap joint 220 protrudes outward from the outer side wall of the screen box 200 and has an arc-shaped groove with an opening facing downward. The arc-shaped groove is used to adapt to the vibration rod 810, and its size can be slightly larger than the vibration rod 810, so as to be able to adaptively adjust the second distance and then adapt to the first distance.

[0090] Specifically, Figure 1-Figure 4As shown, the specific operation of dumping the sand material in the screen box 200 is as follows: taking the first screen box as an example, the power output end of the linear drive member 730 extends to drive the connecting rod 720 to swing upward, and then drives the first screen box to swing upward around the support rod 770, so that the overlapping portion of the first screen box is located above the horizontal. At this time, the swing motor drives the second swing arm 750 to swing outward, so that the vibration rod 810 is completely separated from the overlapping portion of the first screen box. At this time, the distance between the support rod 770 and the vibration rod 810 is greater than the distance between the first pivot shaft 710 and the second pivot shaft 760, and the power output end of the linear drive member 730 retracts to drive the connecting rod 720 to swing downward, and then drives the first screen box to swing downward around the support rod 770, until the first screen box is tipped downward and the sand material inside is poured out, thereby realizing the dumping of the sand material in the screen box. The specific operation of restoring the screen box 200 from the tipping state to the screening state is as follows: the swing motor drives the second swing arm 750 to swing outward. At this time, the distance between the support rod 770 and the vibration rod 810 is greater than the distance between the first pivot shaft 710 and the second pivot shaft 760. The power output end of the linear drive member 730 extends to drive the connecting rod 720 to swing upward, thereby driving the first screen box to swing upward around the support rod 770, so that the overlapping portion of the first screen box is located above the horizontal. Then, the swing motor drives the second swing arm 750 to return to its original position. , and then retract the power output end of the linear drive member 730 to drive the connecting rod 720 to swing downward, and then drive the first screen box to swing downward around the support rod 770, until the overlapping part of the first screen box overlaps the vibration rod 810. At this time, the swing motor can continue to drive the second swing arm 750 to swing back and forth to synchronously drive the first swing arm 740 and the first screen box to swing, thereby realizing horizontal vibration of the first screen box. At the same time, the vibration motor can also drive the vibration rod 810 to rotate to realize vertical vibration of the first screen box.

[0091] In the batching device of the embodiment of the present application, Figure 1-Figure 4 , Figure 6-Figure 9 As shown, the stirring assembly 900 is also included, and the stirring assembly 900 includes a stirring seat 910 and a stirring rod 920 disposed on the stirring seat 910. The stirring seat 910 is connected to the base 100 and is located above the screen box 200, and the stirring rod 920 can extend into the screen box 200. When in use, the stirring rod 920 can rotate to stir the sand in the screen box 200, ensure the uniformity and looseness of the sand in the screen box 200, and facilitate the smooth screening of the sand.

[0092] In the batching device of the embodiment of the present application, the stirring assembly 900 also includes a lateral stirring mechanism 930, which includes a slide 931 and a slide rail 932 slidably connected to the slide 931, the slide rail 932 is horizontally installed on the base 100, and the stirring seat 910 is installed on the slide 931. During use, the slide 931 slides on the slide rail 932, thereby driving the stirring rods 910 and 920 to move along the extension direction of the slide rail 932, which is the length direction of the screen box 200, such as the horizontal direction, thereby realizing the lateral stirring of the sand in the screen box, and further ensuring the uniformity and looseness of the sand. It should be noted that the drive of the slide 931 can be achieved by setting a linear drive member (not shown in the figure) on the base 100, such as an electric cylinder, a hydraulic cylinder or a cylinder. Of course, a motor that outputs torque / torque and a transmission assembly matched therewith can also be selected to achieve it, for example, by a motor and a lead screw assembly. This driving method is relatively conventional and is not limited or explained here.

[0093] In the batching device of the embodiment of the present application, the stirring assembly 900 also includes a second vibration assembly 940, which includes a connecting seat 941 connected between the stirring seat 910 and the sliding seat 931 and a linear vibration driving member 942 arranged on the connecting seat 941, and the linear vibration driving member 942 can drive the stirring seat 910 to reciprocate vertically. Such a setting can realize the up and down reciprocating motion of the stirring seat 910 and the stirring rod 920, and then perform vibration mixing / stirring / loosening of the sand material around it. During operation, the up and down vibration direction of the stirring rod 920 in the second rotating assembly 940 can be set to the opposite direction of the up and down vibration direction of the aforementioned screen box 200, and maintain the same vibration frequency, for example, the vibration frequency range is 6-20Hz, that is, the screen box 200 and the stirring rod 920 are synchronously moved back or toward each other, thereby ensuring that the relative amplitude between the two is the maximum value, and achieving a strong vibration effect.

[0094] In the batching device of the embodiment of the present application, Fig.13 , Fig.14 As shown, the stirring seat 910 can be configured as a disc structure. There are multiple stirring rods 920, and they are arranged at intervals, such as Fig.13 , Fig.14 As shown, 8 stirring rods are provided, which are evenly distributed along the circumference of the stirring seat 910. Of course, other numbers can be provided, which are not limited here; each stirring rod 920 is connected to a stirring motor (not shown in the figure) that drives it to rotate, and the stirring motor is installed on the stirring seat 910; wherein, the rotation speed of the stirring rod 920 can be set to 0.2-1.5 rpm. In addition, each stirring rod 920 can be set to a linkage structure or a separate control structure, and the specific structure can adopt the existing drive and transmission structure, which is not limited or explained here.

[0095] In the embodiment of the present application, a plurality of first blades 921 arranged at intervals are fixedly provided on the outer peripheral wall of the middle part of the stirring rod 920, and the first blades 921 have a wavy structure. The amplitude of the first blade 921 located at the front end of the middle part is greater than the amplitude of the first blade 921 at the rear end, that is, the wave structure of the blades in the middle part of the stirring rod 920 is steep in front and gentle in the back. Such a setting can ensure that the stirring intensity in the deeper lower part of the screen box 200 is stronger, thereby ensuring that the material in the spatial sieve hole part is more uniform and loose, ensuring the screening efficiency of the sieve hole, and at the same time, ensuring that the stirring intensity in the shallower upper part of the screen box 200 is weaker, thereby reducing or even avoiding the splashing of sand.

[0096] The outer peripheral wall at the end of the stirring rod 920 is fixed with a plurality of second blades 922 arranged at intervals, the outer diameter of the end portion is smaller than the outer diameter of the middle portion, and the outer dimensions of the second blades 922 are smaller than the outer dimensions of the first blades 921; preferably, the outer dimensions of the first blades 921 are 2-3 times the outer dimensions of the second blades 922; such an arrangement reduces the stirring resistance at the tip of the stirring rod 920.

[0097] In the embodiment of the present application, a control panel (not shown in the figure) is also provided, for example, a liquid crystal control panel or a touch screen control panel, to control the working state of the screen box 200 and to control the control valve 410, so as to achieve precise control of the coarse, medium and fine ratios of the sand particles.

[0098] For further ease of understanding, the entire workflow / steps of the batching device are exemplarily described as follows:

[0100] S200, introducing circulating sand of different particle sizes into the first screen box, lifting the receiving plate 600 under the first screen box, starting the swing motor and the vibration motor corresponding to the first screen box to vibrate the first screen box horizontally and vertically, and at the same time, starting the linear vibration drive to vibrate the stirring rod 920 vertically, starting the stirring motor to rotate the stirring rod 920, and then screening the sand particles in the first screen box, and the fine sand particles leaking from the sieve holes of the first screen box directly fall into the first storage box; wherein, the first screen box and the corresponding stirring seat 910 have opposite vertical vibration directions and consistent vibration frequencies, taking 6 Hz as an example, and the rotation speed of the stirring rod 920 taking 0.5 rpm as an example, when the circulating sand reaches the preset position of the first screen box (for example, the middle part of the first screen box), stop introducing the circulating sand into the first screen box, continue screening the sand for a preset time (for example, 2 minutes), and then stop screening the sand for the first screen box;

[0101] S300, shut down the stirring rod 920 and the first screen box, put down the receiving tray 600 under the first screen box, lift up the first screen box with the linear drive member 730, swing the second swing arm 750 outward, put down the first screen box with the linear drive member 730, and the first screen box introduces the remaining sand after screening into the receiving tray 600 under the first screen box, and introduces it into the guide trough 300, and then introduces it into the second screen box; wherein, the second screen box and the corresponding stirring seat 910 have opposite vertical vibration directions and consistent vibration frequencies, taking 8Hz as an example, and the rotation speed of the stirring rod 920 taking 0.2 rpm as an example, when the circulating sand reaches the preset position of the second screen box (for example, the middle part of the second screen box), stop introducing the circulating sand into the second screen box, continue screening the sand for a preset time (for example, 2 minutes), and then stop screening the sand for the second screen box;

[0102] S400, lift the receiving plate 600 under the second screen box, start the swing motor and the vibration motor corresponding to the second screen box to vibrate the second screen box horizontally and vertically, and at the same time, start the linear vibration drive to vibrate the stirring rod 920 vertically, start the stirring motor to rotate the stirring rod 920, and then screen the sand in the second screen box, and the medium-diameter sand leaking from the screen hole of the second screen box directly falls into the second storage box;

[0103] S500, shut down the swing motor, vibration motor, linear vibration drive, and stirring motor, and lower the receiving tray 600 below the second screen box. The linear drive 730 lifts up the second screen box, and its second swing arm 750 swings outward, and the second screen box is lowered, and the coarse sand in it is poured into the receiving tray 600 below it, and then the coarse sand is introduced into the third screen box;

[0104] S600, according to the demand, adjust the opening ratio of the control valves at the outlets of the first storage box, the second storage box, and the third storage box, so that the coarse, medium, and fine sands flow into the mixing chamber according to the preset ratio, and then enter the sandblasting cycle operation. Among them, the ratio of coarse, medium, and fine sands can be set to 2:5:3 as an example.

[0105] It should be noted that, in actual operation, according to the amount of sand in the three storage boxes, the excess fine sand is discharged and the coarse sand is increased / supplemented.
