Description

Technical Field

[0001] This application belongs to the technical field of paint production, and specifically relates to a paint storage device for paint production. Background Technology

[0002] Coatings are engineering materials that are applied to the surface of an object and form a tough protective film after drying. They are widely used in construction, industry and other fields. When producing coatings, they need to be stored in coating storage devices to meet the needs of transportation and storage.

[0003] During the application of paint, the paint roller needs to be placed into the paint storage device to pick up the paint. As the amount of paint used increases, the paint level in the storage device gradually drops. When the paint level drops to a certain height, the depth to which the worker needs to dip into the paint storage device increases with each subsequent dip, thus increasing the time required and affecting the efficiency of paint application. Utility Model Content

[0004] This application provides a paint storage device for paint production to improve the efficiency of paint application by workers, thereby improving the efficiency of paint application.

[0005] The technical solution adopted in this application is as follows:

[0006] A paint storage device for paint production includes a barrel body, a barrel lid, and a drive plate. The top of the barrel body is open, and the interior of the barrel body has a receiving cavity. The drive plate is located in the receiving cavity, and the outer peripheral surface of the drive plate contacts the cavity wall. The barrel lid is detachably provided with a pull rod, which can be connected to the drive plate so that the drive plate can move along the axial direction of the barrel body under the pulling action of the pull rod.

[0007] By adopting the above technical solution, when filling the paint, the drive plate is driven to the bottom of the accommodating cavity so that the accommodating cavity can hold a larger amount of paint, and then the lid is sealed to complete the storage of the paint.

[0008] During the application of paint, as the amount of paint picked up by the paint roller gradually increases, the paint level in the bucket gradually decreases. At this point, the worker can remove the pull rod from the bucket lid, connect the pull rod to the drive plate, and apply an upward pulling force to the pull rod. This causes the drive plate to move upward along the axis of the bucket, pushing the paint in the receiving cavity upward to raise the remaining paint level. This reduces the depth to which the worker's arm needs to penetrate the receiving cavity when picking up paint, thus improving the paint picking efficiency and ultimately increasing the painting efficiency.

[0009] Meanwhile, since the outer peripheral surface of the drive plate is in contact with the cavity wall of the accommodating cavity, the drive plate can also be used to scrape the cavity wall of the accommodating cavity, thereby reducing the situation where paint is easily wasted due to paint adhering to the inner wall of the bucket. This improves the user experience on the one hand, and avoids waste of resources on the other.

[0010] Optionally, a sealing element is provided on the outer periphery of the drive plate, and the outer peripheral surface of the sealing element contacts the cavity wall of the accommodating cavity.

[0011] By adopting the above technical solution, since the outer peripheral surface of the drive plate is provided with a sealing element, and the outer peripheral surface of the sealing element contacts the cavity wall of the accommodating cavity, the sealing between the drive plate and the cavity wall can be increased. On the one hand, it prevents the paint from entering the bottom of the drive plate through the gap between the drive plate and the accommodating cavity. On the other hand, it increases the scraping effect of the drive plate on the cavity wall of the accommodating cavity. Furthermore, it increases the clamping force between the drive plate and the cavity wall of the accommodating cavity to ensure the stability of the drive plate after it moves upward.

[0012] Optionally, the bottom of the barrel is provided with an air inlet, which is connected to the accommodating cavity.

[0013] By adopting the above technical solution, when the pull rod moves upward under the action of the drive plate, the air outside the barrel enters the accommodating cavity at the bottom of the drive plate through the air inlet. On the one hand, this can reduce the driving force required for the drive plate to move upward, thereby making it easier to drive the drive plate upward and further improving the user experience. On the other hand, it can also prevent the formation of negative pressure at the bottom of the drive plate, so as to ensure the stability of the drive plate after it moves upward.

[0014] Optionally, the bottom of the barrel is provided with a plurality of supporting ribs, the outer circumferential surface of the barrel is provided with reinforcing ribs that extend from the supporting ribs along the axial direction of the barrel, the interior of the supporting ribs is provided with a bottom air intake channel communicating with the air inlet, and the interior of the reinforcing ribs is provided with a side air intake channel communicating with the bottom air intake channel.

[0015] By adopting the above technical solution, the bottom of the barrel is provided with multiple supporting ribs, which can be used to increase the structural strength of the bottom of the barrel, thereby increasing the structural strength of the paint storage device. Furthermore, the outer circumference of the barrel is provided with reinforcing ribs, which can be used to increase the structural strength of the side of the barrel, thereby increasing the structural strength of the paint storage device. Additionally, the supporting ribs have bottom air inlet channels communicating with the air inlet holes, and the reinforcing ribs have side air inlet channels communicating with the bottom air inlet channels. This allows the paint storage device to be utilized in other ways after the paint in the accommodating cavity has been used, increasing the flexibility of the paint storage device and avoiding resource waste.

[0016] Optionally, a sealing gasket is provided at the bottom of the barrel lid, which can seal the top opening of the side air intake channel.

[0017] By adopting the above technical solution, after the bucket lid is installed on the bucket body, the sealing gasket contacts the top opening of the side air intake channel, thereby enabling the sealing gasket to seal the top opening of the side air intake channel, ensuring the airtightness of the accommodating cavity, and thus ensuring the storage effect of the coating.

[0018] Optionally, an edge is provided at the top edge of the drive plate, and the edge extends circumferentially along the drive plate.

[0019] By adopting the above technical solution, since the top edge of the drive plate is provided with an edge that extends circumferentially along the drive plate, the contact area between the drive plate and the cavity wall can be increased, thereby increasing the connection stability between the drive plate and the cavity and the stability of the drive plate when moving axially along the barrel. On the other hand, when the drive plate is removed from the cavity, the edge can also block the paint to prevent the paint from falling from the edge of the drive plate.

[0020] Optionally, the drive plate is provided with a seal on its exterior, the seal having a sealing section located on the outer periphery of the drive plate and blocking sections located on the top and bottom of the drive plate.

[0021] By adopting the above technical solution, since the seal has a sealing section located on the outer periphery of the drive plate and a blocking section located at the top and bottom of the drive plate, the contact area between the seal and the cavity wall is increased on the one hand, thereby increasing the sealing performance between the drive plate and the cavity. On the other hand, the blocking section can be used to position and limit the sealing section, thereby increasing the connection stability between the seal and the drive plate.

[0022] Optionally, the drive plate has connecting ears on both opposite sides, each connecting ear having a connecting hole, and the pull rod includes a connecting segment that can pass through the connecting hole and a handheld segment located between the connecting segments.

[0023] By adopting the above technical solution, after removing the pull rod from the bucket lid, the pull rod is inserted into the bucket body, and the connecting section is inserted into the connecting hole of the connecting ear. Then, an upward pulling force is applied to the hand-held section, thereby increasing the connection stability between the pull rod and the drive plate to ensure the driving efficiency of the drive plate.

[0024] Optionally, the handheld section is bent so that the pull rod is connected to the connecting lug, and the handheld section can form a handheld space with the drive plate.

[0025] By adopting the above technical solution, due to the curved design of the handheld section and the subsequent installation of the pull rod after the connecting ear, a handheld space can be formed between the handheld section and the drive plate, so as to facilitate the staff to grasp the handheld section. At the same time, it can also minimize the occurrence of the staff's hands coming into contact with the paint when grasping the handheld section.

[0026] Optionally, the bucket lid is provided with clamping ribs, which are located on both sides of the pull rod and can apply clamping force to the pull rod.

[0027] By adopting the above technical solution, since the bucket lid is equipped with clamping ribs, which are located on both sides of the pull rod and can apply clamping force to the pull rod, the connection stability between the pull rod and the bucket lid is increased on the one hand, and the pull rod is made easier to pick up and put down on the other hand.

[0028] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0029] 1. The paint storage device of this application includes a bucket, a lid, and a drive plate. The top of the bucket is open, and the inside of the bucket has a receiving cavity. The drive plate is located in the receiving cavity, and the outer peripheral surface of the drive plate contacts the cavity wall. The lid is detachably equipped with a pull rod, which can be connected to the drive plate so that the drive plate can move along the axial direction of the bucket under the pulling action of the pull rod. This allows the drive plate to push the paint in the receiving cavity upward, thereby increasing the liquid level of the remaining paint in the receiving cavity. This reduces the depth to which the worker's arm needs to enter the receiving cavity when dipping the paint, thus improving the worker's paint dipping efficiency and consequently improving the paint application efficiency.

[0030] 2. The drive plate in this application is provided with a sealing element on its outer periphery. The outer periphery of the sealing element contacts the cavity wall of the accommodating cavity, thereby increasing the sealing between the drive plate and the cavity wall. On the one hand, this prevents the paint from entering the bottom of the drive plate through the gap between the drive plate and the accommodating cavity, and on the other hand, it increases the scraping effect of the drive plate on the cavity wall.

[0031] 3. The bottom of the barrel in this application is provided with an air inlet, which is connected to the accommodating cavity. When the pull rod moves upward under the action of the drive plate, the air outside the barrel enters the accommodating cavity at the bottom of the drive plate through the air inlet, thereby reducing the driving force required for the drive plate to move upward, thus facilitating the upward driving of the drive plate and further improving the user experience.

[0048] Reference Figures 1 to 8 A paint storage device for paint production is disclosed, which includes a barrel body 1, a barrel lid 2, and a drive plate 3. The top of the barrel body 1 is open, and the interior of the barrel body 1 has a receiving cavity. The drive plate 3 is located in the receiving cavity, and the outer peripheral surface of the drive plate 3 contacts the cavity wall. The barrel lid 2 is provided with a pull rod 21 that can be removed and placed. The pull rod 21 can be connected to the drive plate 3 so that the drive plate 3 can move along the axial direction of the barrel body 1 under the pulling action of the pull rod 21.

[0049] When filling the paint, the drive plate 3 is driven to the bottom of the accommodating cavity so that the accommodating cavity can hold more paint, and then the lid 2 is sealed to complete the storage of the paint.

[0050] During the application of the paint, as the amount of paint picked up by the paint roller gradually increases, the paint level in the bucket 1 gradually decreases. At this point, the worker can remove the pull rod 21 from the bucket lid 2 and then connect the pull rod 21 to the drive plate 3. Applying an upward pulling force to the pull rod 21 causes the drive plate 3 to move upward along with the pull rod 21, i.e., the drive plate 3 moves upward along the axial direction of the bucket 1. This pushes the paint in the accommodating cavity upward, increasing the remaining paint level in the accommodating cavity. This reduces the depth to which the worker's arm needs to penetrate the accommodating cavity when picking up the paint, thus improving the worker's paint picking efficiency and consequently, the paint application efficiency.

[0051] Meanwhile, since the outer peripheral surface of the drive plate 3 is in contact with the cavity wall of the accommodating cavity, the drive plate 3 can also be used to scrape the cavity wall of the accommodating cavity, thereby reducing the situation where the paint is easily wasted due to the paint adhering to the inner wall of the barrel 1. This improves the user experience on the one hand, and avoids the waste of resources on the other.

[0052] This application does not specify a particular connection method between the lid 2 and the body 1. Preferably, the lid 2 is threaded onto the body 1 to increase the stability of the connection and facilitate the disassembly of the lid 2. In other embodiments, the lid 2 can also be connected to the body 1 by a snap-fit ​​mechanism.

[0053] In a preferred embodiment, refer to Figure 2 , Figure 7 and Figure 8 A sealing element 31 is provided on the outer periphery of the drive plate 3, and the outer peripheral surface of the sealing element 31 contacts the cavity wall of the accommodating cavity.

[0054] Understandably, the outer peripheral surface of the drive plate 3 contacts the cavity wall of the accommodating cavity through the seal 31.

[0055] Since the outer peripheral surface of the drive plate 3 is provided with a sealing element 31, and the outer peripheral surface of the sealing element 31 contacts the cavity wall of the accommodating cavity, the sealing between the drive plate 3 and the cavity wall of the accommodating cavity can be increased. On the one hand, it prevents the paint from entering the bottom of the drive plate 3 through the gap between the drive plate 3 and the accommodating cavity. On the other hand, it increases the scraping effect of the drive plate 3 on the cavity wall of the accommodating cavity. Furthermore, it increases the clamping force between the drive plate 3 and the cavity wall of the accommodating cavity to ensure the stability of the drive plate 3 after it moves upward.

[0056] Furthermore, refer to Figure 2 The bottom of the barrel 1 is provided with an air inlet 11, which is connected to the accommodating cavity.

[0057] When the lever 21 moves upward under the action of the drive plate 3, the air outside the barrel 1 enters the accommodating cavity at the bottom of the drive plate 3 through the air inlet 11. On the one hand, this can reduce the driving force required for the drive plate 3 to move upward, thereby making it easier to drive the drive plate 3 upward and further improving the user experience. On the other hand, it can also prevent the formation of negative pressure at the bottom of the drive plate 3, so as to ensure the stability of the drive plate 3 after it moves upward.

[0058] This application does not specify the number of air inlets 11; there may be only one or multiple inlets.

[0059] Furthermore, refer to Figures 1 to 5 The bottom of the barrel 1 is provided with multiple support ribs 12, and the outer circumferential surface of the barrel 1 is provided with reinforcing ribs 13 extending from the support ribs 12 along the axial direction of the barrel 1. The interior of the support ribs 12 is provided with a bottom air intake channel 121 communicating with the air intake hole 11, and the interior of the reinforcing ribs 13 is provided with a side air intake channel 131 communicating with the bottom air intake channel 121.

[0060] It is understood that the support ribs 12 extend radially along the barrel body 1, the reinforcing ribs 13 are arranged one-to-one with the support ribs 12, and the bottom air intake channel 121 inside each support rib 12 is connected to the side air intake channel 131 inside the corresponding reinforcing rib 13.

[0061] Because the bottom of the barrel 1 is provided with multiple supporting ribs 12, the structural strength of the bottom of the barrel 1 can be increased by the supporting ribs 12, thereby increasing the structural strength of the paint storage device; and because the outer circumference of the barrel 1 is provided with reinforcing ribs 13, the structural strength of the side of the barrel 1 can be increased by the reinforcing ribs 13, thereby increasing the structural strength of the paint storage device; and because the supporting ribs 12 are provided with a bottom air inlet channel 121 communicating with the air inlet 11, and the reinforcing ribs 13 are provided with a side air inlet channel 131 communicating with the bottom air inlet channel 121, the paint storage device can be utilized in other ways after the paint in the accommodating cavity is used up, thereby increasing the flexibility of the paint storage device and avoiding waste of resources.

[0062] Specifically, when the drive plate 3 moves upward, the air pressure in the bottom space of the drive plate 3 decreases, and the air outside the barrel 1 enters the bottom air intake channel 121 through the side air intake channel 131. The air entering the bottom air intake channel 121 enters the bottom space of the drive plate 3 through the air intake hole 11, so that the air pressure in the bottom space of the drive plate 3 is the same as the air pressure outside the barrel 1.

[0063] Furthermore, refer to Figure 2 and Figure 3 The bottom of the lid 2 is provided with a sealing gasket 22, which can seal the top opening of the side air intake channel 131.

[0064] Understandably, after the lid 2 is installed on the body 1, the sealing gasket 22 contacts the top opening of the side air intake channel 131, thereby sealing the top opening of the side air intake channel 131 to ensure the airtightness of the accommodating cavity and thus ensure the storage effect of the coating.

[0065] In a preferred embodiment, refer to Figure 2 and Figure 7 An edge 32 is provided at the top edge of the drive plate 3. The edge 32 extends circumferentially along the drive plate 3, that is, the edge 32 is a ring structure.

[0066] Since the top edge of the drive plate 3 is provided with an edge 32, and the edge 32 extends along the circumference of the drive plate 3, it can increase the contact area between the drive plate 3 and the cavity wall, thereby increasing the connection stability between the drive plate 3 and the cavity and increasing the stability of the drive plate 3 when moving along the axial direction of the barrel 1. On the other hand, when the drive plate 3 is removed from the cavity, the edge 32 can also block the paint to prevent the paint from falling from the edge of the drive plate 3.

[0067] Furthermore, refer to Figure 2 and Figure 7 The drive plate 3 is provided with a seal 31 on its exterior. The seal 31 has a sealing section 311 located on the outer periphery of the drive plate 3 and a blocking section 312 located on the top and bottom of the drive plate 3.

[0068] Understandably, the cross-section of seal 31 is C-shaped.

[0069] Since the seal 31 has a sealing section 311 located on the outer periphery of the drive plate 3 and a blocking section 312 located on the top and bottom of the drive plate 3, it increases the contact area between the seal 31 and the cavity wall to increase the sealing performance between the drive plate 3 and the cavity. On the other hand, the blocking section 312 can be used to position and limit the sealing section 311 to increase the connection stability between the seal 31 and the drive plate 3.

[0070] Preferably, the seal 31 is made of rubber material to ensure the sealing effect of the seal 31 on the drive plate 3.

[0071] This application does not specify the connection method between the pull rod 21 and the drive plate 3. Preferably, refer to... Figure 2 , Figure 7 and Figure 8 The drive plate 3 has connecting ears 33 on both sides opposite to each other. The connecting ears 33 have connecting holes. The pull rod 21 includes a connecting section 211 that can pass through the connecting hole and a hand-held section 212 located between the connecting sections 211.

[0072] After removing the lever 21 from the lid 2, the lever 21 is inserted into the barrel 1, and the connecting section 211 is inserted into the connecting hole of the connecting ear 33. Then, an upward pulling force is applied to the hand-held section 212, which increases the connection stability between the lever 21 and the drive plate 3, thereby ensuring the driving efficiency of the drive plate 3.

[0073] Preferably, the connecting ear 33 is fixedly connected to the edge 32, and the blocking section 312 at the top of the edge 32 is provided with an avoidance notch corresponding to the connecting ear 33.

[0074] Furthermore, the hand-held section 212 is bent so that after the pull rod 21 is connected to the connecting ear 33, the hand-held section 212 can form a hand-held space with the drive plate 3, so as to facilitate the staff to grasp the hand-held section 212, and at the same time, it can minimize the situation where the staff's hands come into contact with the paint when grasping the hand-held part.

[0075] Preferably, the tie rod 21 is made of iron, so as to ensure the structural strength of the tie rod 21 while allowing the tie rod 21 to deform within a certain range, so as to facilitate the connection of the tie rod 21 to the connecting lug 33.

[0076] In other embodiments, a C-shaped rod is provided at the center of the drive plate 3, and one end of the pull rod 21 is hook-shaped, so that the pull rod 21 can be hooked together with the C-shaped rod, so that the drive plate 3 can be moved axially in the barrel 1 by means of the hooking and cooperation of the pull rod 21 and the C-shaped rod.

[0077] This application does not specify the exact connection method between the pull rod 21 and the lid 2; preferably, refer to... Figure 3 and Figure 6 The bucket lid 2 is provided with clamping ribs 23. The clamping ribs 23 are located on both sides of the pull rod 21 and can apply clamping force to the pull rod 21. This increases the connection stability between the pull rod 21 and the bucket lid 2, and also makes it easier to pick up and put down the pull rod 21.

[0078] Preferably, four clamping ribs 23 are provided, with two clamping ribs 23 located on both sides of one end of the tie rod 21 and the other two clamping ribs 23 located on both sides of the other end of the tie rod 21, so as to increase the fixing stability of the tie rod 21.

[0079] In other embodiments, the lid 2 is provided with a magnet, and the lever 21 is made of iron so that the lever 21 can be magnetically attached to the lid 2.

[0080] In a preferred embodiment, refer to Figure 1 and Figure 2 The barrel body 1 is hinged with a lifting handle 14 to facilitate the movement of the paint storage device.
