[0034] like Figures 1 to 17 As shown, a grinding device that can efficiently grind paint includes a grinding seat 1, a paint containing box 2, a grinding block 3 and a driving assembly, the paint containing box 2 is used to contain paint, a partition 11 is arranged in the middle of the grinding seat 1, the paint containing box 2 is located below the partition 11 and can move forward and backward relative to the grinding seat, a pair of grinding blocks 3 extending into the paint containing box are arranged below the partition, the two grinding blocks 3 are close together and are both elliptical cylindrical structures, the bottom surfaces of the two grinding blocks 3 contact the inner bottom surface of the paint containing box 2, the partition 11 is respectively provided with transverse strip limiting holes 101 above the two grinding blocks, the grinding block is connected to a transmission shaft 31 that passes through the transverse strip limiting hole upward and can move laterally in the transverse strip limiting hole, the transmission shaft 31 is connected to the driving assembly above the partition 11, and the length directions of the two transverse strip limiting holes 101 are located on the same horizontal line. This structure can limit the grinding block 3 to only move and rotate in a straight line relative to the partition 11, and the movement and rotation of the two grinding blocks 3 are driven by the driving assembly.

[0035] In this embodiment, the transmission shaft 31 is sleeved and fixed with a bearing 32, the bearing 32 is sleeved in a sleeve 33, and the first spring 44 is connected to the sleeve 33 toward the middle end. Through this structure of the bearing 32 connection, the first spring 44 can push the transmission shaft 31 to move without affecting the rotation of the transmission shaft 31. The bearing 32 sleeved in the sleeve 33 and the transmission shaft 31 after passing through the bearing 32 can both be connected by a retaining ring (not shown in the drawings), and the bearing 32 can be effectively protected by the connection of the sleeve 33.

[0036] In this embodiment, the driving assembly includes a driving rod 41, a driving gear 42, a transmission gear 43 and a first spring 44. The upper ends of the two transmission shafts 31 are connected to the transmission gears 43. The first spring 44 that pushes the transmission shaft 31 toward the middle is connected between the transmission shaft 31 and the side wall of the grinding seat 1. The driving rod 41 is driven by a driving cylinder 45 to move back and forth relative to the grinding seat. One end of the driving rod 41 extends into the grinding seat and is rotatably connected to the driving gear 42. The driving gear 42 is located between the transmission gears 43 on both sides and is meshed with the two transmission gears at the same time.

[0037] In this embodiment, the grinding seat 1 may further include a housing 12, which is disposed above the partition 11, and the housing 12 seals the two transmission gears 43 of the grinding seat 1 above the partition 11. A guide hole (not shown in the drawings) is provided on the rear side of the housing 12, and the driving rod 41 penetrates through the guide hole, forming a structure in which the front end of the driving rod 41 extends into the grinding seat 1. The driving rod 41 can be restricted by the structure of the guide hole, so that the driving rod 41 can only move forward and backward relative to the grinding seat 1.

[0038] In this embodiment, a connecting frame 13 is provided at the rear portion of the grinding seat 1, and the driving cylinder 45 is fixedly connected to the connecting frame 13. The driving cylinder 45 can be a power element such as a cylinder, a hydraulic cylinder or an electric cylinder with a telescopic rod 451 that can automatically telescope and move. The telescopic rod 451 is fixedly connected to the driving rod 41, so that the driving cylinder drives the driving rod 41 to automatically reciprocate.

[0039] After the paint is placed in the middle of the paint container 2 and the paint container 2 is fixed to the bottom of the partition 11, the driving rod 41 is pushed forward to drive the driving gear 42 to move toward the middle direction of the two transmission gears 43. Fig.10 As shown, the driving gear 42 presses the two transmission gears 43, while overcoming the elastic force of the two first springs 44 to move the two transmission gears 43 to the two sides of the grinding seat 1. At the same time, because the driving gear 42 and the transmission gear 43 are meshed, the two transmission gears 43 are driven to rotate in opposite directions while pushing the two transmission gears 43 to rotate. In this way, the grinding blocks 3 are driven to move to the two sides of the grinding seat 1 and reverse at the same time, thereby driving the two grinding blocks 3 to form an attached Fig.11 Then the driving rod 41 continues to move and moves to the position shown in the attached figure. Fig.12 When the driving gear 42 is located between the two transmission gears 43, the two grinding blocks 3 form a Fig.13 The rotation direction shown is that the long axis endpoints of one end of the two grinding blocks 3 are in contact with each other, and the other long axis endpoints of the two grinding blocks 3 are in contact with the inner wall of the paint containing box 2; then the driving rod 41 continues to move forward and moves to a state where the driving gear 42 loses meshing with the two transmission gears 43; then the driving rod 41 continues to move and moves to a state where the driving gear 42 loses meshing with the two transmission gears 43, which is equivalent to the driving rod 41 being located between the two transmission gears 43, and the two transmission gears 43 lose the obstruction of the driving gear 42 and move toward the middle of the grinding seat 1, thereby forming the shape as shown in the attached figure. Fig.14As shown, the two grinding blocks 3 are driven to move toward the middle of the grinding seat 1, thereby grinding and rolling the paint, and the long axis ends of the grinding blocks 3 can be made to contact the inner wall of the paint containing box 2.

[0040] When the driving rod 41 is pulled backward, the driving gear 42 presses the two transmission gears 43 in the opposite direction, and overcomes the elastic force of the two first springs 44, and overcomes the elastic force of the two first springs 44 to make the two transmission gears 43 move to the two sides of the grinding seat 1 again. At the same time, because the driving gear 42 and the transmission gear 43 are meshed, the two transmission gears 43 are driven to rotate in opposite directions while pushing the two transmission gears 43 to rotate. In this way, the grinding block 3 is driven to move to the two sides of the grinding seat 1 while rotating forward. After that, the driving rod 41 continues to move backward, and the two grinding blocks can be attached in sequence. Fig.13 Status and Fig.12 The driving gear 42 and the two transmission gears 43 lose meshing, and then the two transmission gears 43 lose the blocking of the driving gear 42 and move toward the middle of the grinding seat 1, thereby forming the state as shown in the attached figure again. Fig.14 As shown, the two grinding blocks 3 are driven to move toward the middle again, thereby grinding and rolling the paint again.

[0041] It can be known that the above operation mode pushes the driving rod 41 to move forward and backward, and this movement mode of the driving rod 41 can form an in-and-out movement of the driving gear 42 relative to the two transmission gears 43, thereby forming a short axis end point contact that drives the two grinding blocks 3 to contact repeatedly, and the surfaces of the two grinding blocks 3 and the side walls of the paint storage box 2 are in contact, and the paint is crushed and ground through such contact. In addition, during the process, the surfaces of the two grinding blocks 3 can also keep in contact to form a jaw pattern to keep the paint crushed. Through the reciprocating movement of the driving gear 42 relative to the two transmission gears 43, a reciprocating swing that drives the surfaces of the two grinding blocks 3 to keep in contact can be formed to repeatedly grind and crush the paint. It can be seen that the grinding equipment of the present invention can achieve the grinding of paint through a simple operation mode.

[0042] As attached Figure 3 and 4 As shown, the lower part of the grinding seat 1 has support plates 17 on both sides, and the middle side of the support plates 17 on both sides is recessed to form a step 18, and the steps on both sides are connected to support the bottom surface blocking member 14 of the accommodating box. A row of guide wheels 15 in contact with the bottom surface of the paint accommodating box 2 are provided on the blocking member to reduce the friction resistance of the paint accommodating box 2 when moving.

[0043] The bottom surfaces of the two blocking members 14 are provided with inclined guiding slopes, and the two side support plates at the bottom of the grinding seat are provided with penetrating guiding holes 102 at the giving steps, and the two blocking members are fixedly connected to the guide rods 110 on the side facing away from the middle of the grinding seat, and the guide rods 110 on both sides pass through the corresponding guide holes outwards and are fixedly connected to the handles 16, and the guide rods are sleeved with second springs 19 that push the blocking members toward the middle. After adopting this structure, the elastic force of the second spring 19 pushes the blocking member 14 toward the middle of the grinding seat 1 so that the blocking member extends to the bottom of the two sides of the paint accommodating box 2 to support the bottom surface of the paint accommodating box.

[0044] When the paint accommodating box 2 needs to be connected under the partition 11, the paint accommodating box 2 is placed on a plane (such as a table), and the grinding seat 1 is pressed from top to bottom toward the paint accommodating box 2, so that the paint accommodating box 2 is embedded in the grinding seat 1. During the process, the paint accommodating box 2 overcomes the pressure of the second spring 19 under the action of the guide slopes of the two blocking members 14 and moves toward the support plate 17, until the support plate 17 is located on the same plane as the paint accommodating box 2, and then the paint accommodating box 2 is lifted up to the bottom surface of the partition 11, at which time the two blocking members 14 lose the restriction of the side edges of the paint accommodating box 2 and move out of the step 18 under the elastic force of the second spring 19, so that the blocking member 14 supports the bottom surface of the paint accommodating box 2 and restricts the paint accommodating box 2 to move only between the partition 11 and the blocking member 14.

[0045] A push-pull pin 111 is fixedly connected to the lower side of the driving rod 41, and a pull rod 21 is arranged on the rear side of the paint accommodating box 2. The pull rod 21 is provided with a positioning hole 211 that cooperates with the push-pull pin 111. After the paint accommodating box 2 is connected under the partition 11, the push-pull pin 111 passes through the positioning hole 211. With this connection structure, the paint accommodating box 2 can move with the movement of the driving rod 41, so as to promote the paint to be fully spread in the paint accommodating box 2 and move at any time, so that the two grinding blocks 3 can grind the paint more evenly.

[0046] In addition, both sides of the bottom surface of the paint accommodating box 2 are hingedly connected to a pivot plate 22 for supporting the paint accommodating box 2 after flipping downward. The structure of the connection between the pivot plate 22 and the bottom surface of the paint accommodating box 2 can be as shown in the attached figure. Fig.17As shown, the two ends of the pivot plate 22 are connected by connecting shafts 221, and the connecting shafts 221 pass through the pivot parts 25 provided on both sides of the bottom of the paint receiving box 2, so as to realize the rotation of the pivot plate 22. After the pivot plate 22 is rotated to vertical, the bottom of the pivot plate 22 is flush with the bottom of the grinding seat 1. After the grinding is completed, the two pivot plates 22 can be rotated to vertical, and then the two handles 16 are respectively held by both hands to pull the two blocking members 14 into the two giving way steps 18, and then the grinding seat 1 can be directly taken out upwards to complete the separation of the paint receiving box 2. During this process, the two pivot plates 22 vertically support the paint containing box 2 to prevent the paint containing box 2 from losing support and falling after the two blocking members 14 move to the yielding steps 18, thereby preventing the paint in the paint containing box 2 from splashing out due to inertia after the paint containing box 2 falls to a plane, and at the same time preventing the paint containing box 2 from being damaged.

[0047] In addition, if attached Fig.15 and 16 As shown, a limit assembly for controlling the flipping of the pivot plate 22 is also provided at the bottom of the paint containing box 2. The limit assembly includes a limit screw 51, a pivot member 54, a connecting rod 52 and a limit rod 53. The limit screw 51 is arranged along the front-to-back direction and one end is located on the bottom surface of the paint containing box 2 and the other end extends out of the paint containing box 2. The limit screw 51 passes through a fixing seat fixedly connected to the bottom surface of the paint containing box. A threaded hole threadedly matched with the limit screw 51 is provided on the fixing seat. The limit screw 51 is connected to the pivot member 54 rotatably matched with it at one end of the bottom surface of the paint containing box 2. The connection method can be that a bearing is fixed at the end of the limit screw 51, and the bearing is embedded in and fixed to the pivot member 54. Through this structure, the limit screw 51 and the pivot member 54 can rotate axially fixed to each other. The two sides of the pivot member 54 are hinged with the connecting rods 52 respectively, and the ends of the two connecting rods 52 away from the pivot member 54 are hinged with the limiting rods 53 for blocking the pivot plate 22 to limit its downward flipping. Limiting holes 202 are set on both sides of the bottom of the paint containing box 2, and the two limiting rods 53 pass through the two limiting holes 202 respectively and can slide horizontally.

[0048] After adopting the structure of the above-mentioned limiting assembly, during the process of grinding paint (that is, when the pivot plate is not needed), the two pivot plates 22 can be rotated to fit against the bottom surface of the paint receiving box 2, and then the limiting screw 51 is rotated to drive the two connecting rods 52 to swing, thereby pushing the two limiting rods 53 to move to respectively limit the two pivot plates 22 to the bottom surface of the paint receiving box 2, so as to avoid the pivot plates 22 flipping downward and contacting the plane on which the grinding seat 1 is placed, thereby avoiding affecting the movement of the paint receiving box 2.

[0049] In addition, as attached Fig.17 As shown, the bottom surface of the paint accommodating box 2 is fixedly connected with a baffle plate 23 on the outer side of the pivot plate 22, and the connecting shaft 221 of the pivot plate 22 is covered with a torsion spring 24 for pushing the pivot plate 22 to swing downward. The structure of the torsion spring 24 can make the pivot plate 22 maintain the elastic force of rotating toward the baffle plate 23, and when the pivot plate 22 rotates toward the baffle plate 23, the pivot plate 22 can be blocked by the baffle plate 23, so that the pivot plate 22 can be kept vertical. Further, when the pivot plate 22 is blocked by the limiting rod 53 and remains attached to the bottom surface of the paint accommodating box 2, after the two limiting rods 53 are moved toward the middle of the paint accommodating box 2 by rotating the limiting screw 51, the pivot plate 22 can automatically flip to a vertical position after losing the blockage of the limiting rod 53. It can be seen that the structure of connecting the torsion spring 24 can facilitate the operation of the two pivot plates 22 and improve the convenience of operation.

[0050] A grinding method of the grinding device capable of efficiently grinding paint as described above comprises the following steps:

[0051] (1) Pour the paint into the paint accommodating box 2. At this time, the pivot plate 22 at the bottom of the paint accommodating box 2 is swung down to a vertical state to support the paint accommodating box 2. Then, the grinding seat 1 is put on the paint accommodating box 2 from top to bottom, so that the paint accommodating box 2 is connected under the partition 11 of the grinding seat 1, and the two grinding blocks 3 are both located in the paint accommodating box 2. The blocking member extends to the bottom of the two sides of the paint accommodating box 2 to support the bottom surface of the paint accommodating box. Then, the pivot plate 22 is swung up to be close to the bottom surface of the paint accommodating box 2.

[0052] (2) Control the driving rod 41 to move forward and backward, drive the paint accommodating box to move forward and backward, and drive the driving gear 42 to move forward and backward between the two transmission gears 43, so that the driving gear 42 drives the transmission gear 43 to rotate, thereby driving the two grinding blocks 3 to rotate, and the short axis end points and the long axis end points of the two grinding blocks 3 repeatedly contact each other, so that the two grinding blocks 3 can grind the paint in the paint accommodating box 2;

[0053] (3) After the paint is ground, the two pivot plates 22 are swung down again to a vertical position to support the paint accommodating box 2 on the plane on which the grinding seat 1 is placed. Then, the blocking member is pulled outward to separate from the bottom surface of the paint accommodating box. Then, the grinding seat 1 is lifted up from the paint accommodating box 2. After that, the ground paint can be taken out.

[0054] Through the above grinding process, it can be known that when grinding paint, the present invention only needs to repeatedly push and pull the driving rod 41, which is more convenient and labor-saving than the method of holding the ramming hammer and rotating it back and forth on the grinding bowl. During the grinding process, when the paint accommodating box 2 moves toward the grinding seat 1, it can be partially moved out of the grinding seat 1 laterally, so as to facilitate the observation of the fineness of the paint grinding at any time.

[0055] In summary, in the structure of the present invention, by driving the driving rod 41 to move relative to the grinding seat 1, the two grinding blocks 3 can be driven to move and swing in the paint receiving box 2, so that the surfaces of the two grinding blocks 3 contact each other and the surfaces of the two grinding blocks 3 contact the inner wall of the paint receiving box 2. The collision formed by this contact process can crush the paint poured into the paint receiving box 2 to form a grinding process. In addition, in the process of the driving rod 41 moving relative to the grinding seat 1, the paint receiving box 2 is driven to move relative to the grinding seat 1 under the partition 11, so that the paint can be driven to shake in the paint receiving box 2, which can promote the mixing of multiple different colors of paint, and make the paint spread and move arbitrarily in the paint receiving box 2, so that the two grinding blocks 3 can grind all the paints in the paint receiving box 2, which is conducive to improving the quality of paint grinding. It can be seen that when grinding paint, the present invention only needs to drive the driving rod to move back and forth relative to the grinding seat, which is very convenient.
