Description

Technical Field

[0001] This utility model relates to the field of coating production technology, specifically a filter bucket for coatings. Background Technology

[0002] During the paint production process, impurities often get mixed in. These impurities may come from the raw materials themselves or metal shavings, dust and other particles in the production equipment. In order to ensure the quality of the paint, it must be effectively filtered. Currently, most paint filtration devices on the market use mesh or multi-layer filter paper as the filter medium.

[0003] A search revealed Chinese patent CN220758186U, which discloses a filtration device for coatings, belonging to the field of coating filtration technology. This filtration device includes a guide barrel, a sieve support, a sieve, and a filter screen. The guide barrel has an opening at its upper end and a discharge port at its bottom. The sieve support includes a bracket, a base, and a handle. The bracket is mounted on the opening, the base is located at the bottom of the bracket, and the handle is attached to the bracket. The sieve is mounted on the sieve support. The filter screen matches the diameter of the sieve; when filtering coatings, the filter screen is simply placed on top of the sieve. This structure prevents the filter screen and sieve from deforming due to the weight of the coating during filtration, and allows for convenient, quick, and clean replacement of the sieve and filter screen, ensuring both high filtration efficiency and stable product quality.

[0004] Although the above-mentioned utility model can filter coatings, the filter screen is laid on top of the sieve, and the stability of the filter screen is poor. The staff also need to hold the filter screen with their hands, which further increases the labor intensity of the staff and the cumbersomeness of the operation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filter bucket for coatings, which has the advantages of good stability of the sieve plate. It solves the problem that when the filter screen is laid on top of the sieve, the stability of the filter screen is poor, and the staff still need to hold the filter screen with their hands, which further increases the labor intensity of the staff and the cumbersomeness of the operation.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a filter bucket for coatings, comprising a coating bucket, with handles fixed to the top of both the left and right sides of the coating bucket, a filter mechanism for filtering coatings provided in the inner cavity of the coating bucket, and a buffer mechanism for cushioning provided on the lower side of the coating bucket.

[0007] The filtration mechanism includes a first filter plate, a second filter plate, two connecting rods, two limiting plates, two fixing boxes, two locking blocks, two return springs, two push plates, and two insert blocks. The first filter plate and the second filter plate are arranged vertically inside the paint bucket. The two connecting rods are respectively fixed to the left and right ends between opposite sides of the first and second filter plates. The two limiting plates are fixed to the left and right ends of the upper surface of the first filter plate. The two fixing boxes are respectively fixed to the top of the left and right sides of the paint bucket. The two locking blocks are respectively fixed to the lower surface of the top of the two limiting plates. The two return springs are respectively fixed to opposite sides of the inner sidewalls of the two fixing boxes. The two push plates are fixed to opposite sides of the two return springs. The two insert blocks are respectively fixed to opposite sides of the two push plates.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the filter barrel for coatings can effectively remove impurities of different particle sizes through the multi-stage filtration method, thereby improving the quality and uniformity of the coating. In addition, the two filter plates can be quickly disassembled, and the filter plates can be directly removed for cleaning, avoiding the problem of clogging and reduced filtration efficiency caused by the accumulation of impurities on the filter plates, thus protecting the service life of the filter plates and reducing maintenance costs.

[0009] Furthermore, a discharge pipe is connected to the bottom of the left side of the paint bucket, and a switch valve is fixed to the other end of the discharge pipe.

[0010] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to remove the paint, the paint in the paint bucket can be discharged through the discharge pipe by opening the switch valve.

[0011] Furthermore, the outer diameters of the first and second filter plates are respectively adapted to the inner diameter of the paint bucket, and the pore diameter of the first filter plate is larger than that of the second filter plate.

[0012] The beneficial effects of adopting the above-mentioned further solution are: the first filter plate has a larger pore size, which can quickly filter out large particulate impurities in the coating, reduce filtration resistance, and improve filtration efficiency; the second filter plate has a smaller pore size, which is used to further filter fine particles and ensure the purity of the coating.

[0013] Furthermore, the limiting plate has an inverted L-shaped cross-section, and slots are provided at both ends of the upper surface of the paint bucket, with the inner dimensions of the slots matching the dimensions of the card blocks.

[0014] The advantages of adopting the above-mentioned further solution are that the filter plate can be fixed inside the paint bucket, and it is also easy to disassemble.

[0015] Furthermore, the upper surface of the fixing box is provided with a guide hole that matches the size of the push plate, and the other end of the insert block passes through the fixing box and extends into the inner cavity of the slot.

[0016] Furthermore, the left side of the card block has an insertion hole that matches the size of the insertion block, and the inner wall of the opposite side of the card slot at both ends has a slot that matches the size of the insertion block.

[0017] The beneficial effect of adopting the above-mentioned further solution is that when it is necessary to disassemble the filter plate, simply push the push plate and the insert block can be disengaged from the insertion hole in the card block, and at the same time the return spring automatically resets.

[0018] Furthermore, the buffer mechanism includes a fixed frame, a buffer plate, and multiple buffer dampers. The fixed frame is located on the lower side of the paint bucket, the buffer plate is fixed to the lower surface of the paint bucket, and the buffer dampers are fixed between the fixed frame and the buffer plate on opposite sides.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the buffer mechanism effectively absorbs and mitigates the impact and vibration experienced by the paint bucket during use through the elastic deformation of the buffer plate and the energy dissipation mechanism of buffer damping. This not only protects the stability and service life of the paint bucket, but also ensures the quality and uniformity of the paint, and avoids layering, bubbles or other quality problems caused by violent shaking of the paint.

[0020] Furthermore, the buffer plate is a rubber plate, and multiple buffer dampers are evenly distributed between the fixed frame and the opposite side of the buffer plate.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, through the dual action of the buffer plate and the buffer damping, the vibration amplitude of the paint bucket is significantly reduced, and finally stability is achieved. This buffering mechanism protects the paint bucket from damage.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] 1. This coating filter can effectively remove impurities of different particle sizes through its multi-stage filtration system, improving the quality and uniformity of the coating. The two filter plates can be quickly disassembled, allowing for direct cleaning and avoiding clogging and reduced filtration efficiency caused by impurities accumulating on the filter plates. This protects the lifespan of the filter plates and reduces maintenance costs.

[0024] 2. The filter bucket for this paint uses a buffer mechanism that effectively absorbs and mitigates the impact and vibration experienced by the paint bucket during use through the elastic deformation of the buffer plate and the energy dissipation mechanism of the buffer damping. This not only protects the stability and service life of the paint bucket, but also ensures the quality and uniformity of the paint, avoiding stratification, bubbles or other quality problems caused by violent shaking.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1 In this embodiment, a filter bucket for paint includes a paint bucket 1. Handles 2 are fixed to the top of both the left and right sides of the paint bucket 1. The inner cavity of the paint bucket 1 is provided with a filter mechanism 3 for filtering paint. A buffer mechanism 4 for buffering is provided on the lower side of the paint bucket 1.

[0032] In this embodiment, a discharge pipe 5 is connected to the bottom of the left side of the paint bucket 1. A switch valve 6 is fixed at the other end of the discharge pipe 5. When the paint needs to be taken out, the paint in the paint bucket 1 can be discharged through the discharge pipe 5 by opening the switch valve 6.

[0033] Please see Figures 2 to 3In order to filter the paint, the filtration mechanism 3 in this embodiment includes a first filter plate 31, a second filter plate 32, two connecting rods 33, two limiting plates 34, two fixing boxes 35, two locking blocks 36, two return springs 37, two push plates 38 and two insert blocks 39. The first filter plate 31 and the second filter plate 32 are arranged vertically in the inner cavity of the paint bucket 1. The two connecting rods 33 are respectively fixed at the left and right ends between the opposite sides of the first filter plate 31 and the second filter plate 32. The produced paint is poured down along the first filter plate 31. The paint first passes through the first filter plate 31, and the first filter plate 31 filters out the large particulate impurities in the paint. At this time, the paint needs to pass through the second filter plate 32, which can filter out the small particulate impurities in the paint. The filtered paint can be collected in the inner cavity of the paint bucket 1.

[0034] In this embodiment, two limiting plates 34 are fixed to the left and right ends of the upper surface of the first filter plate 31, two fixing boxes 35 are fixed to the top of the left and right sides of the paint bucket 1, two locking blocks 36 are fixed to the lower surface of the top of the two limiting plates 34, two return springs 37 are fixed to the opposite side of the inner wall of the two fixing boxes 35, two push plates 38 are fixed to the opposite side of the two return springs 37, and two insert blocks 39 are fixed to the opposite side of the two push plates 38. By moving the push plate 38 away from the paint bucket 1, the movement of the push plate 38 will squeeze the return spring 37. At the same time, the movement of the push plate 38 will synchronously drive the insert block 39 to move until the insert block 39 is completely removed from the insertion hole on the left side of the locking block 36. The locking block 36 can be released. After the locking block 36 on the other side is released, the two limiting plates 34 can be pulled upward at the same time. Then the first filter plate 31 and the second filter plate 32 can be moved out of the inner cavity of the paint bucket 1.

[0035] In this embodiment, the outer diameters of the first filter plate 31 and the second filter plate 32 are respectively adapted to the inner diameter of the paint bucket 1. The aperture of the first filter plate 31 is larger than the aperture of the second filter plate 32. The cross-sectional shape of the limiting plate 34 is an inverted L shape. The left and right ends of the upper surface of the paint bucket 1 are provided with slots, and the size of the inner cavity of the slot is adapted to the size of the card block 36.

[0036] The upper surface of the fixing box 35 is provided with a guide hole that matches the size of the push plate 38. The other end of the insert block 39 passes through the fixing box 35 and extends into the inner cavity of the slot. The left side of the slot block 36 is provided with an insertion hole that matches the size of the insert block 39. The inner wall of the opposite side of the slots at both ends is provided with a slot that matches the size of the insert block 39.

[0037] In addition, a lever is fixed to the front of the push plate 38, with one end penetrating through and extending to the front of the fixing box 35. The front of the fixing box 35 is provided with a fixing hole that matches the size of the lever, so that the staff can move the push plate 38.

[0038] It should be noted that the multi-stage filtration system can effectively remove impurities of different particle sizes, improving the quality and uniformity of the coating. In addition, the two filter plates can be quickly disassembled, and can be directly removed for cleaning, avoiding the problems of clogging and reduced filtration efficiency caused by the accumulation of impurities on the filter plates.

[0039] Please see Figure 4 In order to cushion the paint bucket 1, the cushioning mechanism 4 in this embodiment includes a fixed frame 41, a buffer plate 42 and multiple buffer dampers 43. The fixed frame 41 is located on the lower side of the paint bucket 1, the buffer plate 42 is fixed on the lower surface of the paint bucket 1, and the buffer dampers 43 are fixed between the fixed frame 41 and the buffer plate 42 on opposite sides. When the paint bucket 1 is impacted by paint, the rubber buffer plate 42 first undergoes elastic deformation to absorb part of the impact energy. As the impact force is transmitted, the buffer dampers 43 convert the remaining impact energy into heat energy or other forms of energy through their internal damping mechanism, further reducing the vibration amplitude.

[0040] In this embodiment, the buffer plate 42 is a rubber plate, and multiple buffer dampers 43 are evenly distributed between the fixed frame 41 and the opposite side of the buffer plate 42.

[0041] Understandably, since the buffer damper 43 is evenly distributed between the fixed frame 41 and the buffer plate 42, it can ensure that the impact force is evenly dispersed and absorbed in multiple directions. Through the dual action of the buffer plate 42 and the buffer damper 43, the vibration amplitude of the paint bucket 1 is significantly reduced, and finally stability is achieved. This buffering mechanism not only protects the paint bucket 1 from damage, but also avoids the paint from layering, bubbles or other quality problems caused by violent shaking.

[0042] The working principle of the above embodiments is as follows:

[0043] (1) When filtering the coating, the produced coating is poured downwards along the first filter plate 31. The coating first passes through the first filter plate 31, which filters out large particulate impurities in the coating. At this time, the coating needs to pass through the second filter plate 32, which filters out small particulate impurities in the coating. The filtered coating can be collected in the inner cavity of the coating tank 1. When the coating needs to be removed, the switch valve 6 can be opened, and the coating in the coating tank 1 can flow out through the discharge pipe 5. When the second filter plate 32 is removed, the push plate 38 can be moved away from the paint bucket 1. The movement of the push plate 38 will compress the return spring 37. At the same time, the movement of the push plate 38 will drive the insertion block 39 to move until the insertion block 39 is completely removed from the insertion hole on the left side of the locking block 36. The locking block 36 can be released. After the locking block 36 on the other side is released, the two limiting plates 34 can be pulled upward at the same time. Then the first filter plate 31 and the second filter plate 32 can be moved out of the inner cavity of the paint bucket 1.

[0044] (2) When the paint bucket 1 is impacted by the paint, the rubber buffer plate 42 first undergoes elastic deformation to absorb part of the impact energy. As the impact force is transmitted, the buffer damper 43 converts the remaining impact energy into heat energy or other forms of energy through its internal damping mechanism, further reducing the vibration amplitude. Since the buffer damper 43 is evenly distributed between the fixed frame 41 and the buffer plate 42, it can ensure that the impact force is evenly dispersed and absorbed in multiple directions. After the dual action of the buffer plate 42 and the buffer damper 43, the vibration amplitude of the paint bucket 1 is significantly reduced, and finally stability is achieved. This buffering mechanism not only protects the paint bucket 1 from damage, but also avoids the paint from layering, bubbles or other quality problems caused by violent shaking.
