Description

Technical Field

[0001] This invention relates to the field of spraying machine technology, and more specifically to a horizontal vacuum spraying machine with multi-purpose spraying technology. Background Technology

[0002] Currently, the working principle of existing vacuum spraying machines is as follows: a motor drives a paddle rotor or auger blades to rotate, causing the material particles to repeatedly tumble and stir within the tank. While forcibly moving the material particles, oil or bacterial solutions are sprayed in. Under vacuum negative pressure, the oil or bacterial solutions adhere to the surface of the material particles, achieving uniform coating. However, existing vacuum spraying machines have the following technical drawbacks: 1. During the movement of material particles within the tank, their trajectories are random and uncontrollable, resulting in frequent and violent collisions with the tank walls and agitation components. The more forced the movement, the more uncontrollable the collisions, and the easier it is for brittle particles to break, making it difficult to achieve a stable and controllable material spraying process. 2. Most of the vacuum spraying machines currently in use are vertically designed. When spraying a large proportion of oily materials or bacterial liquids, for materials with small particle sizes, the liquid film on the surface of such materials thickens, the adhesion between material particles increases, and the material particles are easily squeezed into clumps when they are at the bottom of the tank. The stirring components have difficulty scraping the material at the bottom, which leads to uneven spraying and poor product quality. Summary of the Invention

[0031] The technical solutions in the embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] like Figures 1 to 16 As shown, the present invention provides a horizontal vacuum spraying machine with multi-purpose spraying technology, comprising: Rack 1; A flip-up frame 2 is flip-mounted on the frame 1; Roller 3, which is rotatably mounted on the tilting frame 2; The stirring mechanism 4 is disposed inside the drum 3; The rotating mechanism 5 is mounted on the tilting frame 2 and is used to drive the roller 3 to rotate around the central axis; The flipping mechanism 6 is mounted on the frame 1 and is used to drive the flipping frame 2 to flip. The flipping frame 2 drives the roller 3 to flip back and forth between the feeding position, the processing position, and the discharge position. The feeding mechanism 7 is located on the top of the frame 1. When the roller 3 is in the feeding position, the opening of the roller 3 faces upward and can be connected to the feeding mechanism 7. The receiving mechanism 8 is located at the bottom of the frame 1. When the roller 3 is in the discharge position, the opening of the roller 3 faces downward and can be connected to the receiving mechanism 8. A sealing cover mechanism 9 is movably mounted on the frame 1 and configured to move back and forth between a blocking position and a clearance position. When the roller 3 is in the processing position, the opening of the roller 3 corresponds to the sealing cover mechanism 9. When the sealing cover mechanism 9 is in the blocking position, it blocks the opening of the roller 3. When the sealing cover mechanism 9 is in the clearance position, it separates from the opening of the roller 3. A vacuuming mechanism 10 is disposed on the sealing cover mechanism 9 and is configured to perform vacuuming and depressurization on the inside of the roller 3 when the sealing cover mechanism 9 is in the sealing position. The liquid supply mechanism 11 is disposed on the sealing cover mechanism 9 and is configured to spray coating liquid into the inside of the roller 3 when the sealing cover mechanism 9 is in the sealing position.

[0033] In this embodiment, the present invention can perform processes such as feeding, sealing, vacuuming, oil spraying, stirring, pressure relief, unloading, and return to the starting position. Its working principle is as follows: The flipping mechanism 6 drives the drum 3 to flip to the feeding position. The feeding mechanism 7 feeds the material to be vacuum-sprayed into the drum 3. After the material is fed, the flipping mechanism 6 drives the drum 3 to flip to the processing position. The sealing cover mechanism 9 seals the opening of the drum 3. Then, the vacuuming mechanism 10 performs vacuuming on the inside of the drum 3. After the vacuuming is completed, the rotating mechanism 5 drives the drum 3 to rotate continuously. The spraying liquid is injected into the inside of the drum 3 by the liquid supply mechanism 11, and the material is repeatedly thrown up and stirred by the stirring mechanism 4 to ensure that the spraying liquid and the material are in full contact, thereby forming a stable vacuum spraying treatment for the material. After the material is sprayed, the drum 3 continues to rotate, and the vacuuming mechanism 10 depressurizes the inside of the drum 3. After the depressurization treatment is completed, the drum 3 stops rotating. Then, the sealing cover mechanism 9 disengages from the opening of the drum 3, and the flipping mechanism 6 drives the drum 3 to flip to the discharge position. The material inside the drum 3 is released from the drum 3 under the action of gravity and is collected and processed by the receiving mechanism 8.

[0034] It is important to understand that the mixing mechanism 4 is fixed inside the drum 3. As the drum 3 rotates continuously, the mixing mechanism 4 rotates synchronously with the drum 3. The mixing mechanism 4 enables the batch of materials to be repeatedly thrown up and dispersed while rolling, forming a stable and controllable motion trajectory. This not only ensures that the sprayed liquid and the materials are in full contact, but also prevents the repeatedly rolled materials from being squeezed into clumps, effectively reducing the breakage rate of the materials and ensuring that the finished products meet the production quality standards.

[0035] It should be noted that this invention is applicable to vacuum spraying of materials with different particle sizes. It can not only achieve full contact and mixing between the spraying liquid and the material, thereby achieving efficient and uniform spraying on the material surface, but also effectively improve the problem of material particle breakage and agglomeration during the spraying process, ensuring the quality of the finished product. It can also achieve the continuity of related processing steps and improve the processing efficiency of materials.

[0036] The aforementioned flipping frame 2 includes: A flip frame 201 is provided, one side of which is rotatably mounted on the frame 1 via a rotating shaft 202, and the other side of which is connected to the output end of the flipping mechanism 6. Fixed gripper 203, two fixed grippers 203 are provided, and the two fixed grippers 203 are arranged at the front end of the flipping frame 201; The quick-release gripper 204 is provided in two. The two quick-release grippers 204 and the two fixed grippers 203 together form a clamping structure for clamping the roller 3. The two ends of each quick-release gripper 204 are respectively detachably set at the ends of the two fixed grippers 203 located on the same side by the first locking bolt 205. Both ends of the two fixed grippers 203 are provided with roller assemblies 206 that can fit against the outer surface of the roller 3. Both ends of the two quick-release grippers 204 are provided with locking parts 207 for locking the roller assemblies 206. The rotating mechanism 5 is located at the rear end of the flipping frame 201, and its output end is threaded to the bottom of the roller 3.

[0037] It should be noted that the combination of the fixed gripper 203 and the quick-release gripper 204 can stably clamp the front part of the roller 3, while the rear end of the roller 3 is supported by the rotating mechanism 5 and the roller 3 is rotated so that the roller 3 can rotate stably on the tilting frame 2. When the roller 3 is in the clamped state, the four roller assemblies 206 are fixed in place by the locking action of the locking member 207, and form a self-positioning and anti-deviation effect, so that the roller 3 can accurately stop at the predetermined position, and then form precise docking with the feeding mechanism 7, the receiving structure, and the sealing cover mechanism 9 respectively. It also avoids wear between the roller 3 and the fixed gripper 203 and the quick-release gripper 204 respectively when the roller 3 rotates, ensuring the service life of the tilting frame 2. After the quick-release gripper 204 is removed from the fixed gripper 203, the roller 3 can form rolling contact with the roller assembly 206 and disengage from the clamping position of the fixed gripper 203, avoiding the roller 3 being scratched during disassembly. The output of the rotating mechanism 5 is threadedly connected to the bottom of the roller 3, and the overall roller 3 is quick, simple and stable to assemble and disassemble.

[0038] The stirring mechanism 4 includes: The positive propeller blade 401 is provided in multiple ways. The multiple positive propeller blades 401 are spaced apart on the inner side of the drum 3. Each positive propeller blade 401 is configured as a spiral plate that is distributed counterclockwise along the central axis of the drum 3 and has a structure that is narrow at the top and wide at the bottom. The top ends of the multiple positive propeller blades 401 are all located on the same circular path, and the included angle between the top ends of two adjacent positive propeller blades 401 is equal. The reverse propeller blade 402 is provided in multiple ways. The multiple reverse propeller blades 402 are spaced apart at the center of multiple positive propeller blades 401. Each of the reverse propeller blades 402 is configured as a spiral plate that is spirally distributed clockwise along the central axis of the roller 3 and has a structure that is wider at the top and narrower at the bottom. A baffle plate 403 is provided in multiple manner, and the multiple baffle plates 403 are respectively arranged at the top of multiple positive propeller blades 401. Each baffle plate 403 is configured to form an angle with the plate surface of the positive propeller blade 401 and is perpendicular to the inner side surface of the roller 3.

[0039] It should be noted that the functional characteristics of the stirring mechanism 4 described in this invention are as follows: For the configured positive propeller blades 401, multiple positive propeller blades 401 are welded to the inner side of the drum 3, spaced apart from each other, and distributed in a counterclockwise spiral. Each positive propeller blade 401 adopts a structure that is narrow at the top and wide at the bottom. The wide design at the bottom of the positive propeller blade 401 is used to increase the contact surface with the material, which can ensure that a sufficient amount of material can be stirred and conveyed upward each time the drum 3 rotates, avoiding the situation where the material is concentrated at the bottom when the drum 3 is tilted. The design of the positive propeller blades 401 gradually narrowing from the bottom to the top can reduce the material layer by layer during the process of conveying to the top of the drum 3, thereby making the material relatively dispersed when it is thrown at the top of the drum 3, so that each material can fully contact the sprayed liquid. For the configured reverse propeller blades 402, multiple reverse propeller blades 402 are welded to the inner side of multiple positive propeller blades 401, spaced apart from each other, and distributed in a clockwise spiral. Each reverse propeller blade 402 adopts a structure that is wider at the top and narrower at the bottom. The wide design at the top of the reverse propeller blade 402 can catch a large amount of material that has been thrown up and fallen from the top of the positive propeller blade 401 and sprayed with the spraying liquid, and convey it to the bottom of the drum 3. The narrow design at the bottom of the reverse propeller blade 402 is because the material near the bottom of the drum 3 has accumulated sufficiently, and there is no need to convey too much material downward. In summary, as the positive propeller blade 401 and the negative propeller blade 402 rotate simultaneously with the drum 3, the change in the position of the material inside the drum 3 forms a continuous cycle between the bottom and top of the drum 3, thereby forming a stable and controllable motion trajectory. The function of the baffle plate 403 is that when the positive propeller blade 401 delivers the material to the top, the baffle plate 403 can prevent the material from continuing to move forward along the drum wall to the drum opening position due to the spiral inertia, forcing the material to be returned at the top position of the positive propeller blade 401, realizing the motion trajectory of being thrown up and falling, and being continuously sprayed by the spraying liquid.

[0040] The rotating mechanism 5 includes: The gearbox 501 is located at the rear end of the tilting frame 201, and its output end is threaded to the bottom of the roller 3. A drive motor 502 is mounted on a reduction gearbox 501, and its output end is connected to the input end of the reduction gearbox 501.

[0041] It is understandable that the drive motor 502 serves as the power source for the rotation of the drum 3, and the gearbox 501 is used to increase the torque to reduce the speed of the drive motor 502, thereby improving the rotation control accuracy of the drum 3 and ensuring the stable rotation of the drum 3.

[0042] The flipping mechanism 6 includes: The drive assembly includes a housing 601, a servo motor 602, a worm gear 603, and a worm 604. The housing 601 is mounted on the frame 1. The servo motor 602 is mounted on the front side of the housing 601, and its output end extends into the interior of the housing 601 and is connected to the worm gear 603. The worm 604 meshes with the worm gear 603, and its two ends extend through the left and right sides of the housing 601 and are mounted on the housing 601. The left end of the worm 604 is located on the other side of the tilting frame 201. The buffer assembly includes a second locking bolt 605, a buffer pad 606, a buffer friction rod 607, and a buffer rubber wheel 608. The buffer pad 606 is sleeved on the right end of the worm gear 604 and is set on the right side of the housing 601 by the second locking bolt 605. Multiple buffer friction rods 607 are provided and are vertically arranged on the outer side of the buffer pad 606, and are distributed in a circular array with the central axis of the worm gear 604 as the center. The buffer rubber wheel 608 is located on the right end of the worm gear 604, and the sides of the multiple buffer friction rods 607 are all in contact with the outer circumferential surface of the buffer rubber wheel 608.

[0043] It should be noted that the output of the servo motor 602 drives the tilting frame 201 to tilt via the worm gear 603 and worm 604. Simultaneously, the buffer rubber wheel 608 rotates synchronously via the transmission of the worm 604. Due to the slight gap in the meshing between the worm gear 603 and the worm 604, when the servo motor 602 stops momentarily, the worm 604 cannot stop immediately and will still generate a slight inertial rotation, causing a deviation in the positioning of the drum opening of the roller 3. Therefore, to address this issue, the tilting mechanism 6 is equipped with multiple buffer friction rods 607 arranged in a circular array at the buffer pad 606. When the worm 604 rotates, the multiple buffer friction rods 607 continuously generate frictional resistance with the buffer rubber wheel 608, effectively suppressing the inertial rotation of the worm 604. When the servo motor 602 suddenly stops, the frictional resistance can effectively eliminate the rotational error caused by the gap between the worm 604 and the worm gear 603, ensuring that the drum opening of the roller 3 can accurately stop at the predetermined position each time.

[0044] The feeding mechanism 7 includes: The feed pipe 701 is installed through the top of the frame 1. The bottom end face of the feed pipe 701 is set as an inclined surface. An inclined cover plate 702 is provided on the outer edge of the bottom end of the feed pipe 701. The limiting sleeve 703 is provided in at least two, and the at least two limiting sleeves 703 are provided through the top of the frame 1, and are radially symmetrically distributed between each other with the central axis of the feed pipe 701 as the center. The lower mounting ring 708 is provided with at least two limiting rods 705 that can be sleeved with the limiting sleeve 703; Upper mounting ring 704, wherein the upper mounting ring 704 is sleeved on the outer circumferential surface of the feed pipe 701; A lifting cylinder 706 is installed on the top of the frame 1. The output end of the lifting cylinder 706 is connected to the upper mounting ring 704 to drive the feed pipe 701 to move up and down. Position sensor 707 is disposed on the top of frame 1. Position sensor 707 is communicatively connected to lifting cylinder 706. Position sensor 707 is used to detect the position of upper mounting ring 704.

[0045] It should be noted that the top of the feed pipe 701 is used to connect to the equipment for supplying materials. When the drum 3 is in the feeding position, the lifting cylinder 706 drives the feed pipe 701 downward through the upper mounting ring 704 so that the bottom end of the feed pipe 701 is tightly connected with the opening of the drum 3. The position sensor 707 detects the upper mounting ring 704, which confirms that the feed pipe 701 is in place and sends a signal to stop the driving of the lifting cylinder 706. Then, materials can be fed into the drum 3 through the feed pipe 701. After the materials are fed, the lifting cylinder 706 lifts the feed pipe 701 to prevent the feed pipe 701 from obstructing the subsequent rotation of the drum 3. The inclined cover plate 702 can tightly cover the opening of the drum 3 to prevent material leakage. The limiting sleeve 703 and the limiting rod 705 are used to prevent the feed pipe 701 from shifting during the lifting process and to ensure the stable connection between the feed pipe 701 and the opening of the drum 3.

[0046] The receiving mechanism 8 includes: The receiving channel is located at the bottom of the frame 1 and is configured as an arc-shaped slide structure that slopes from top to bottom.

[0047] It should be noted that the lowest position of the receiving channel is used for external material conveying equipment. The receiving channel, which has an arc-shaped slide structure, receives material from inside the roller 3 so that the material slides down the receiving channel to the lowest position under the action of gravity, thereby facilitating the centralized reception and processing of the sprayed material.

[0048] The sealing cap mechanism 9 includes: Two propulsion cylinders 901 are provided, and the two propulsion cylinders 901 are arranged on both sides of the frame 1; Support rail 902, two support rails 902 are provided, and the two support rails 902 are arranged on both sides of the frame 1; The sliding bracket 903 is provided in two, and the two sliding brackets 903 are slidably mounted on the two support rails 902 in a one-to-one correspondence. One end of the two sliding brackets 903 is connected to the output end of the two propulsion cylinders 901 in a one-to-one correspondence. The cover plate 904 is installed, and the other ends of the two sliding brackets 903 are respectively connected to the outer peripheral surface of the cover plate 904 to support the cover plate 904. The push cylinder 901 drives the sliding brackets 903 to move back and forth, so as to drive the cover plate 904 to move back and forth between the blocking position and the avoidance position. A rolling bearing 301 is fitted on the outer side of the opening of the roller 3. A sealing plug ring 302 is provided in the gap between the inner and outer rings of the rolling bearing 301. A first annular sealing strip 303 is provided on the upper surface of the rolling bearing 301.

[0049] It should be noted that the propulsion cylinder 901 drives the sliding bracket 903 to move back and forth, thereby causing the mounting cover 904 to move back and forth between the blocking position and the clearance position. During this movement, the sliding bracket 903 slides on the support rail 902. Based on the stable support and limiting function of the support rail 902, the mounting cover 904 can move smoothly. When the roller 3 is in the processing position and the mounting cover 904 is in the blocking position, the mounting cover 904 covers the opening of the roller 3, and the inner side of the mounting cover 904 is pressed tightly against the first annular sealing strip. On 303, the gap between the cover plate 904 and the roller 3 is sealed. At the same time, the sealing ring 302 can form a good sealing effect on the gap between the inner and outer rings of the rolling bearing 301. Thus, after the cover plate 904 and the roller 3 are connected, it can ensure that the inside of the roller 3 is completely isolated from the outside world, so as to realize the subsequent vacuuming process. When the roller 3 rotates, the outer ring of the rolling bearing 301 is fixed, while the inner ring of the rolling bearing 301 rotates stably with the roller 3, so that the roller 3 can rotate freely while the cover plate 904 seals and blocks the opening of the roller 3.

[0050] The vacuum pumping mechanism 10 includes: The exhaust pipe 1001 has its end extending through the inner side of the mounting cover plate 904. The first pneumatic ball valve 1002 is installed on the air extraction pipe 1001.

[0051] It should be noted that the end of the suction pipe 1001 away from the mounting cover plate 904 is used to connect to an external vacuuming device to achieve vacuuming inside the drum 3. The first pneumatic ball valve 1002 is used to open or close the suction pipe 1001. When it is necessary to vacuum or depressurize inside the drum 3, the corresponding process can be performed by opening the first pneumatic ball valve 1002. The operation is fast and stable.

[0052] The outer side of the mounting cover 904 is provided with a through mounting port 905, and the liquid supply mechanism 11 includes: A transparent cover plate 1101 is sealed and closed at the mounting opening 905; Injection tube 1102, wherein multiple injection tubes 1102 are provided and are disposed through the transparent cover plate 1101. Each injection tube 1102 is threadedly connected to two fixing nuts 1103, and the two fixing nuts 1103 are clamped on both sides of the transparent cover plate 1101. A second annular sealing strip 1104 is provided between each injection tube 1102 and the transparent cover plate 1101. One end of the multiple injection tubes 1102 located inside the transparent cover plate 1101 is respectively connected to a one-way valve 1106 through a folded tube 1105. A nozzle 1107 is provided at the end of the one-way valve 1106 away from the folded tube 1105. The first liquid supply pipe assembly includes a first arc-shaped pipe 1108, a first straight pipe 1109, and a plurality of first flexible hoses 1110. The first arc-shaped pipe 1108 is disposed on the outer side of the mounting cover plate 904. One end of the first arc-shaped pipe 1108 is a closed end, and the other end of the first arc-shaped pipe 1108 is connected to the end of the first straight pipe 1109. One end of the plurality of first flexible hoses 1110 is connected to the side of the first arc-shaped pipe 1108. The second liquid supply pipe assembly includes a second arc-shaped pipe 1111, a second straight pipe 1112, and a plurality of second flexible hoses 1113. The second arc-shaped pipe 1111 is disposed on the outer side of the mounting cover plate 904. One end of the second arc-shaped pipe 1111 is a closed end, and the other end of the second arc-shaped pipe 1111 is connected to the end of the second straight pipe 1112.

The other ends of the multiple first hoses 1110 and the other ends of the multiple second hoses 1113 are respectively connected to the end of the multiple injection tubes 1102 located outside the transparent cover plate 1101.

[0053] It should be noted that the first and second liquid supply pipe groups are respectively used to connect to the liquid storage devices storing different spraying liquids. When the sealing cap mechanism 9 blocks the opening of the roller 3, different liquid storage devices are supplied with liquid independently through the first and second liquid supply pipe groups according to the actual material processing requirements. The first group of spraying liquids can be directly sprayed into the roller 3 through the first straight pipe 1109, the first arc-shaped pipe 1108, the second flexible hose 1113, the injection pipe 1102, the folded pipe 1105, the one-way valve 1106, and the nozzle 1107. Inside, the second set of spraying liquid can be directly sprayed into the inside of the roller 3 through the second straight pipe 1112, the second arc-shaped pipe 1111, the second flexible hose 1113, the injection pipe 1102, the folded pipe 1105, the one-way valve 1106, and the nozzle 1107. Based on the material throwing changes at different rotation speeds of the storage tank, the orientation of the nozzle 1107 is adjusted by the folded pipe 1105, and multiple nozzles 1107 spray the spraying liquid simultaneously, which can ultimately form a good liquid atomization effect so that the spraying liquid can better contact the material.

[0054] It should be noted that staff can directly observe the material throwing and spraying inside the roller 3 through the transparent cover 1101 without stopping the machine to check; each injection tube 1102 is clamped to both sides of the transparent cover 1101 by two fixing nuts 1103, allowing for free disassembly and replacement of the injection tube 1102. At the same time, the injection tube 1102 is equipped with a second annular sealing strip 1104 to ensure a sealed state at the penetration point.

[0055] It also includes a powder spraying mechanism 12, which includes: The powder spraying tube 1201 has its end extending through the inner side of the mounting cover plate 904, and its surface is provided with a powder inlet 1202.

[0056] It should be noted that after the vacuum spraying of the material is completed, the cleaning powder can be put into the powder spraying pipe 1201 through the powder inlet 1202, and then the cleaning powder inside the powder spraying pipe 1201 can be blown into the roller 3 by the blower 1203. Then, the water source is connected to the feeding mechanism 7 to inject clean water into the roller 3. Then, the rotating mechanism 5 drives the roller 3 to rotate, which can realize the cleaning treatment inside the roller 3. The water after the roller 3 is cleaned can be received by the receiving mechanism 8 and discharged centrally for treatment.

[0057] The frame 1 is provided with multiple support feet 13. Each support foot 13 includes a support column 1301, a weighing sensor 1302, and a balance pad 1303. The top of the support column 1301 is connected to the frame 1, and the balance pad 1303 is connected to the bottom of the support column 1301 through the weighing sensor 1302. The weighing sensor 1302 is communicatively connected to the lifting cylinder 706.

[0058] It should be noted that the support foot 13 consists of three parts: a support column 1301, a weighing sensor 1302, and a balance pad 1303. The balance pad 1303 directly touches the ground, ensuring the frame 1 is placed stably. When material is fed into the roller 3 through the feeding mechanism 7, the weighing sensor 1302 detects the weight change of the roller 3 in real time. When the material input reaches the preset weight value, feeding stops, and the weighing sensor 1302 sends a signal to the lifting cylinder 706. The lifting cylinder 706 then raises the feeding pipe 701, causing the feeding pipe 701 to leave the opening of the roller 3, so that the roller 3 can move its position subsequently. The entire process is completed automatically without manual intervention, ensuring accurate control of the feeding amount each time.
