Description

Technical Field

[0001] This invention relates to the field of material feeding technology, specifically a precision material feeding device for a cleaning machine. Background Technology

[0002] Cleaning machines are used to flush and filter contaminants generated or introduced into hydraulic systems during manufacturing, assembly, use, and maintenance. They can also be used for the periodic maintenance and filtration of working fluids to improve cleanliness, avoid or reduce malfunctions caused by contamination, and thus ensure the high performance, high reliability, and long service life of hydraulic system equipment.

[0003] For example, a patent entitled "A Precision Feeding System for a Cleaning Machine" (patent application number: CN202320850677.9) discloses a method that uses limiting blocks and guide wheels to achieve precise feeding of a trolley, feeding in the front-back or left-right directions of the cleaning machine, and is applicable to parts of different sizes. However, after multiple feedings, parts tend to accumulate in the same position, resulting in incomplete cleaning of certain areas of the parts. Summary of the Invention

[0004] To overcome the problem that parts tend to accumulate in the same position after multiple loadings, resulting in incomplete cleaning of some parts, this invention provides a precision loading device for a cleaning machine, including a base, on the top of which a motor housing is installed.

[0005] A loading mechanism is disposed above the base. The loading mechanism includes a placement component and a pushing component. The pushing component pushes the parts to be cleaned in the placement component into the cleaning machine.

[0006] The feeding mechanism is located above the base. The feeding mechanism includes a third lifting rod, a slide plate is installed on the top of the third lifting rod, and an extension component is installed on the outside of the slide plate. The third lifting rod controls the position of the extension component by driving the slide plate to lift and lower, thus pushing the parts into the cleaning machine through different positions.

[0007] Preferably, a first enclosure plate is installed on the top of the base, and two first enclosure plates are provided and arranged symmetrically, and a motor is installed inside the motor box.

[0008] Preferably, the loading mechanism further includes:

[0009] A rotating shaft is connected to the output end of a motor. A chassis is mounted on the top of the rotating shaft, a central column is mounted on the top of the chassis, and a top plate is mounted on the top of the central column. The top plate is made of magnetic material.

[0010] A sliding ring is slidably connected to the outside of the central column. The sliding ring is connected to the pushing component and the placing component. Multiple sliding rings are provided. The sliding rings are made of magnetic material. The sliding rings can be attracted and fixed to the top plate and to each other, which facilitates the protection of parts when moving equipment.

[0011] Preferably, the actuating component includes:

[0012] A fixing box is installed outside the sliding ring. Multiple fixing boxes are provided. A push rod is installed inside the fixing box. A wave plate is installed at the end of the push rod away from the fixing box.

[0013] The first lifting rod has a fixed end mounted on the chassis and a telescopic end connected to the fixed box.

[0014] The second lifting rod has its fixed end installed inside the fixed box, and multiple fixed boxes are connected by the second lifting rod.

[0015] Preferably, the placement component includes:

[0016] A placement frame is installed outside the sliding ring. A first telescopic rod is installed on the top of the placement frame. A connecting rod is installed outside the first telescopic rod. A buckle plate is installed outside the connecting rod to protect the parts to be cleaned and prevent the parts from falling when the equipment moves.

[0017] The mounting plate is installed inside the placement frame by screws, and a cotton strip is provided on the top of the mounting plate. Multiple cotton strips are provided and evenly distributed.

[0018] Preferably, the feeding mechanism further includes:

[0019] A fixed frame is installed on the outside of the first enclosure panel, the sliding plate is slidably connected to the inside of the fixed frame, and the third lifting rod is installed inside the fixed frame;

[0020] A second enclosure is mounted above the base, and a connecting rod is mounted on the top of the second enclosure, with a handle mounted on the outside of the connecting rod.

[0021] Preferably, the extension component includes:

[0022] A discharge plate is installed on the outside of the slide plate, and a protective plate is installed on the top of the discharge plate;

[0023] The telescopic curved rod is installed at the bottom of the discharge plate. A second telescopic rod is installed on the outside of the telescopic curved rod. An extension plate is installed on the outside of the second telescopic rod to extend the movement space of the parts to be cleaned, so that multiple parts to be cleaned fall into the cleaning machine from different positions, reducing the possibility of parts overlapping. A guardrail is installed on the top of the extension plate. There are three telescopic curved rods, three second telescopic rods and three extension plates.

[0024] This invention provides a precision feeding device for a cleaning machine. It has the following advantages:

[0025] 1. This cleaning machine uses a precision feeding device, employing a loading mechanism and a feeding mechanism to place and feed the parts to be cleaned. Existing feeding machines tend to cause parts to accumulate in the same location within the cleaning machine after multiple loading cycles, resulting in large overlaps and incomplete cleaning of certain areas. Therefore, a loading mechanism and a feeding mechanism are installed to load parts into different placement frames, completing the feeding process according to the cleaning sequence. Simultaneously, the feeding mechanism is adjusted to deliver different parts into the cleaning machine through different positions, reducing the possibility of part accumulation and overlap, thus solving the aforementioned problems.

[0026] 2. This cleaning machine uses a precision feeding device, employing a loading mechanism to place and protect the parts to be cleaned. Two sets of placement frames and clamps at different heights are symmetrically arranged to hold and protect the parts, preventing them from falling during equipment movement. Removable mounting plates and cotton strips are also installed inside the placement frames to absorb oil and grease from the surfaces of the parts, extending the equipment's lifespan and reducing the frequency of thorough cleaning. The height and angle of the parts to be cleaned are controlled by a motor, a pushing component, and a placement component, facilitating the unloading of each part according to the cleaning sequence.

[0027] 3. This cleaning machine uses a precision feeding device. A feeding mechanism, in conjunction with a loading mechanism, completes the feeding of parts into the cleaning machine. By incorporating a third lifting rod and a sliding plate, the height of the extension assembly can be easily adjusted according to the height of the cleaning machine, preventing damage to parts during discharge or water splashing within the cleaning machine due to an excessively high discharge position.

[0028] 4. This cleaning machine uses a precision feeding device, which controls the position of the parts to be cleaned as they enter the machine by setting up an extension assembly. By setting up three extension plates of different lengths, the extension plates contact the discharge plate, providing four different discharge positions. This allows the parts to enter the cleaning machine through different positions, reducing the possibility of accumulation between parts and minimizing the overlapping area between them. This facilitates the separation of parts during the vibration cleaning process, resulting in a more thorough cleaning. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0039] like Figures 1-8As shown, the present invention provides a technical solution: including a base 1, and a motor housing 2 is installed on the top of the base 1;

[0040] The loading mechanism 3 is located above the base 1. The loading mechanism 3 includes a placement component 306 and a pushing component 305. The pushing component 305 pushes the parts to be cleaned in the placement component 306 into the cleaning machine.

[0041] The feeding mechanism 5 is located above the base 1. The feeding mechanism 5 includes a third lifting rod 505. A slide plate 503 is installed on the top of the third lifting rod 505. An extension component 504 is installed on the outside of the slide plate 503. The third lifting rod 505 controls the position of the extension component 504 by driving the slide plate 503 to lift and lower, and pushes the parts into the cleaning machine through different positions.

[0042] The top of the base 1 is equipped with a first enclosure 4. There are two first enclosures 4, which are arranged symmetrically. The motor is installed inside the motor box 2. The bottom of the base 1 is equipped with casters.

[0043] Before using the equipment, adjust the loading mechanism 3 and place the parts to be cleaned into it. Then adjust the loading mechanism 3 to align the parts to be cleaned with the feeding mechanism 5 according to the cleaning sequence. Turn on the feeding mechanism 5 and push the parts to be cleaned into the cleaning machine.

[0044] Loading mechanism 3 also includes:

[0045] A rotating shaft 301 is connected to the output end of a motor. A chassis 302 is mounted on the top of the rotating shaft 301. A central column 303 is mounted on the top of the chassis 302. A top plate 307 is mounted on the top of the central column 303. The top plate 307 is made of magnetic material.

[0046] Sliding ring 304 is slidably connected to the outside of central column 303. Sliding ring 304 is connected to pushing component 305 and placing component 306. Multiple sliding rings 304 are provided. Sliding ring 304 is made of magnetic material.

[0047] Before using the equipment, the placement component 306 is in its initial state, aligned with the gaps in the first side panels 4 on both sides. Adjust the placement component 306, the pushing component 305, and the motor, and manually place the parts to be cleaned into the placement component 306.

[0048] Subsequently, according to the cleaning sequence, the placement component 306, the pushing component 305, and the motor are adjusted, and the height of the feeding mechanism 5 is adjusted at the same time to complete the feeding of the parts to be cleaned, so that the parts to be cleaned can enter the cleaning machine.

[0049] Drive component 305 includes:

[0050] The fixed box 3051 is installed outside the sliding ring 304. Multiple fixed boxes 3051 are provided. A push rod 3054 is installed inside the fixed box 3051. A wave plate 3055 is installed at the end of the push rod 3054 away from the fixed box 3051. When pushing the part to be cleaned, the push rod 3054 is activated. The push rod 3054 drives the wave plate 3055 to move. The wave plate 3055 contacts the part to be cleaned and pushes the part to be cleaned into the feeding mechanism 5.

[0051] The first lifting rod 3052 has its fixed end mounted on the chassis 302 and its telescopic end connected to the fixed box 3051. The first lifting rod 3052 is used to drive the fixed box 3051 and the sliding box to lift and lower, thereby controlling the lifting and lowering of the placement component 306.

[0052] The second lifting rod 3053 has its fixed end installed inside the fixing box 3051, and multiple fixing boxes 3051 are connected through the second lifting rod 3053.

[0053] When pushing the parts to be cleaned, push rod 3054 is activated, which drives the corrugated plate 3055 to move. The corrugated plate 3055 contacts the parts to be cleaned and pushes them into the feeding mechanism 5. After the pushing operation is completed, push rod 3054 is adjusted to its initial state, and push rod 3054 drives the corrugated plate 3055 back to its original position.

[0054] The placement component 306 includes:

[0055] A placement frame 3061 is provided, and a push rod 3054 passes through the placement frame 3061. The placement frame 3061 is installed outside the sliding ring 304. A first telescopic rod 3062 is installed on the top of the placement frame 3061. A connecting rod 3063 is installed outside the first telescopic rod 3062. A buckle plate 3064 is installed outside the connecting rod 3063. The buckle plate 3064 is set as an arc plate.

[0056] Mounting plate 3065 is screwed inside placement frame 3061. Multiple cotton strips 3066 are evenly distributed on the top of mounting plate 3065. Mounting plate 3065 is a detachable component. With multiple cotton strips 3066 on its surface, if the surface of the parts to be cleaned is covered with oil, most of the oil flowing from the contact point between the parts and mounting plate 3065 will be absorbed by the cotton strips 3066, thus reducing the amount of dirt flowing onto the bottom plate of placement frame 3061. After multiple loading operations, workers can disassemble and replace mounting plate 3065 and cotton strips 3066 to extend the equipment's lifespan and reduce the frequency of thorough manual cleaning.

[0057] Before using the equipment, adjust the motor. The motor drives the rotating shaft 301, chassis 302, central column 303, and sliding ring 304 to rotate, which in turn drives the placement component 306 outside the sliding column to rotate. Align the placement component 306 with the gaps in the first side panels 4, open the first telescopic rod 3062. The first telescopic rod 3062 drives the connecting rod 3063 and the buckle plate 3064 to move upward. At this time, the opening of the placement frame 3061 is exposed. Adjust the stroke of the first lifting rod 3052 and the second lifting rod 3053, and manually place the parts to be cleaned into the four placement frames 3061 respectively, with the parts to be cleaned on the four mounting plates 3065 respectively, in contact with the cotton strips 3066.

[0058] Then, the first telescopic rod 3062 is adjusted to its initial state. The first telescopic rod 3062 drives the connecting rod 3063 and the buckle plate 3064 back to their original positions, and the buckle plate 3064 protects the parts to be cleaned.

[0059] Before the material discharge operation, the motor is adjusted. The motor drives the rotating shaft 301, chassis 302, central column 303, and sliding ring 304 to rotate, which in turn drives the placement component 306 outside the sliding column to rotate. After the placement component 306 is aligned with the feeding mechanism 5 and the height of the feeding mechanism 5 is adjusted, the push rod 3054 is activated. The push rod 3054 drives the wave plate 3055 to move. The wave plate 3055 pushes the parts to be cleaned until they fall into the feeding mechanism 5 and gradually enter the cleaning machine.

[0060] By setting up a loading mechanism 3, two sets of placement frames 3061 and buckle plates 3064 at different heights are symmetrically arranged to place and protect the parts to be cleaned, preventing them from falling during equipment movement. Simultaneously, a removable mounting plate 3065 and cotton strips 3066 are installed inside the placement frame 3061 to absorb oil stains flowing from the surface of the parts to be cleaned, extending the equipment's service life and reducing the frequency of thorough cleaning by workers. The height and angle of the parts to be cleaned are controlled by a motor, a push assembly 305, and a placement assembly 306, facilitating the unloading of each part according to the cleaning sequence.

[0061] The feeding mechanism 5 also includes:

[0062] The fixed frame 502 is installed on the outside of the first enclosure 4. The sliding plate 503 is slidably connected to the inside of the fixed frame 502. The third lifting rod 505 is installed inside the fixed frame 502. The first enclosure 4 is provided in two sets, and each set of the first enclosure 4 is provided with two first enclosures. The two first enclosures 4 are connected by the fixed frame 502.

[0063] The second enclosure 501 is installed above the base 1. A connecting rod 506 is installed on the top of the second enclosure 501, and a handle 507 is installed on the outside of the connecting rod 506.

[0064] Before using the equipment, adjust the stroke of the third lifting rod 505 according to the height of the cleaning machine. The third lifting rod 505 drives the slide plate 503 and the extension component 504 to move until the extension component 504 is slightly higher than the inlet of the cleaning machine.

[0065] Extension component 504 includes:

[0066] The discharge plate 5041 is installed on the outside of the slide plate 503. The side of the discharge plate 5041 near the loading mechanism 3 is set as arc shape. A protective plate is installed on the top of the discharge plate 5041. There are two protective plates, which are symmetrically arranged.

[0067] Telescopic bending rod 5042 is installed at the bottom of discharge plate 5041. A second telescopic rod 5043 is installed on the outside of the telescopic bending rod 5042. An extension plate 5044 is installed on the outside of the second telescopic rod 5043. A guardrail 5045 is installed on the top of the extension plate 5044. There are three telescopic bending rods 5042, three second telescopic rods 5043 and three extension plates 5044. The lengths of the three extension plates 5044 are different, and the end of the extension plate 5044 away from the telescopic bending rod 5042 is set as an arc.

[0068] Before using the equipment, activate the telescopic bend 5042 corresponding to the shortest extension plate 5044. The telescopic bend 5042 will move the extension plate 5044 away from the slide plate 503. Then activate the second telescopic rod 5043, which will move the extension plate 5044 upward until its upper surface is flush with the upper surface of the discharge plate 5041, and the extension plate 5044 and the discharge plate 5041 are connected. Manually push the handle 507 to adjust the position of the equipment. Under the push of the wave plate 3055, the parts to be cleaned move through the discharge plate 5041 to the extension plate 5044, and then enter the cleaning machine through the extension plate 5044.

[0069] Then, the other two telescopic bending rods 5042 are opened in sequence, and the size of the extended plate 5044 is increased from small to large. The parts are pushed into the cleaning machine from different positions, reducing the possibility of the parts to be cleaned piling up and reducing the overlapping parts between the parts. Under the cleaning of the cleaning machine, the parts are easier to separate and the cleaning is more thorough.

[0070] The position of the parts to be cleaned entering the cleaning machine is controlled by setting the extension component 504. By setting three extension plates 5044 of different lengths, the extension plates 5044 are made to contact the discharge plate 5041, providing four different discharge positions. This allows the parts to be cleaned to enter the cleaning machine through different positions, reducing the possibility of accumulation between the parts and reducing the overlapping area between the parts. This facilitates the separation of parts during the vibration cleaning process of the cleaning machine, resulting in a more thorough cleaning.

[0071] Working principle: Before using the equipment, adjust the motor. The motor drives the rotating shaft 301, chassis 302, central column 303, and sliding ring 304 to rotate, which in turn drives the placement component 306 outside the sliding column to rotate. Align the placement component 306 with the gaps in the first side panels 4, open the first telescopic rod 3062. The first telescopic rod 3062 drives the connecting rod 3063 and the buckle plate 3064 to move upward. At this time, the opening of the placement frame 3061 is exposed. Adjust the stroke of the first lifting rod 3052 and the second lifting rod 3053, and manually place the parts to be cleaned into the four placement frames 3061 respectively, with the parts to be cleaned on the four mounting plates 3065 respectively, in contact with the cotton strips 3066.

[0072] Then, the first telescopic rod 3062 is adjusted to its initial state. The first telescopic rod 3062 drives the connecting rod 3063 and the buckle plate 3064 back to their original positions, and the buckle plate 3064 protects the parts to be cleaned.

[0073] Before the material discharge operation, the motor is adjusted. The motor drives the rotating shaft 301, the chassis 302, the central column 303, and the sliding ring 304 to rotate, which in turn drives the placement component 306 outside the sliding column to rotate.

[0074] Adjust the stroke of the third lifting rod 505 according to the height of the washing machine. The third lifting rod 505 drives the slide plate 503 and the extension assembly 504 to move until the discharge plate 5041 in the extension assembly 504 is slightly higher than the inlet of the washing machine. Adjust the stroke of the first lifting rod 3052 and the third lifting rod 505 in the feeding mechanism 5 accordingly to align the placement frame 3061 with the discharge plate 5041.

[0075] Open the telescopic bend 5042 corresponding to the shortest extension plate 5044. The telescopic bend 5042 drives the extension plate 5044 to move away from the slide plate 503. Then open the second telescopic rod 5043. The second telescopic rod 5043 drives the extension plate 5044 upward until the upper surface of the extension plate 5044 is flush with the upper surface of the discharge plate 5041, and the extension plate 5044 and the discharge plate 5041 are connected together. Manually push the handle 507 to adjust the position of the equipment. Under the push of the wave plate 3055, the parts to be cleaned move through the discharge plate 5041 to the extension plate 5044, and then enter the cleaning machine through the extension plate 5044.

[0076] Then, the other two telescopic bending rods 5042 are opened in sequence, and the size of the extended plate 5044 is increased from small to large. The parts are pushed into the cleaning machine from different positions, reducing the possibility of the parts to be cleaned piling up and reducing the overlapping parts between the parts. Under the cleaning of the cleaning machine, the parts are easier to separate and the cleaning is more thorough.

[0077] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
