Description

Technical Field

[0001] This utility model relates to the technical field of coating production feeding machines, specifically an automatic metering feeding machine for coating production. Background Technology

[0002] Paint is a material that is applied to the surface of an object to form a firmly adhering, continuous film, providing protection, decoration, and other special functions. A paint production feeder is a device used to precisely add various paint raw materials.

[0003] In the comparative case, patent publication number CN210058161U, this utility model belongs to the technical field of paint production equipment, and in particular to an automatic metering and feeding machine for paint production. It includes a base, a box fixedly connected to the top of the base, a square groove extending through one side of a fixed column, an infrared sensor fixedly connected to the square groove, a trapezoidal groove on one side of the top of the box, a rotating rod movably connected to one side of the inner cavity of the trapezoidal groove via a bearing, a metering box fixedly connected to the outer side of the rotating rod, a fixed block fixedly connected to the other side of the metering box, a rotary motor fixedly connected to the center of the bottom of the inner cavity of the box, and a rotating shaft movably connected to the front side of the rotary motor. The rotating rod facilitates the rotation of the metering box, thereby removing the raw material from the metering box and allowing the metered raw material to be removed. The trapezoidal groove facilitates the storage of the metering box, preventing residual raw material from being left in the metering box when the raw material is removed, thus preventing inaccurate metering and delays in operational efficiency.

[0004] However, during the implementation of the relevant technology, the following problems were found in the above-mentioned automatic metering and feeding machine for paint production. In the comparative case, a rotating rod is fixedly connected to the bottom of the metering box on the outside. The two ends of the rotating rod are movably connected to one side of the trapezoidal groove cavity through bearings. One end of the rotating rod is movably connected to the rotating shaft through a belt, which facilitates the rotation of the metering box and the removal of the raw material in the metering box. This ensures the accuracy of the metering and feeding. The metering accuracy of the existing feeding machine is crucial when filling paint. Too much material is easily wasted, and too little material cannot reach the standard value, which reduces the working efficiency of the feeding machine in accurate metering.

[0005] Therefore, the feeding machine needs to be redesigned and modified to effectively prevent the problems that arise when the feeding machine is filling paint, where metering accuracy is crucial, too much material will easily lead to waste, and too little material will fail to meet the standard value. Utility Model Content

[0022] 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.

[0023] like Figures 1 to 4 As shown, the present invention provides an automatic metering and feeding machine for paint production, comprising:

[0024] A filling machine 1 is provided with a conveying track 2 on its inner side. A screw feeder 3 is fixedly installed on the top of the filling machine 1. A metering mechanism 4 is placed on the right side of the top of the conveying track 2.

[0025] The measuring mechanism 4 includes a tray 41, a hollow cylinder 42, a weighing sensor 43, and a controller 44. The tray 41 is placed on the right side of the top of the conveying track 2. Hollow cylinders 42 are opened at both the front and back ends of the top of the tray 41. A weighing sensor 43 is installed at the bottom of the inner wall of the hollow cylinder 42. The controller 44 is fixedly connected to the front end of the filling machine 1. Limiting mechanisms 5 are fixedly connected to both the front and back ends of the top of the filling machine 1.

[0026] refer to Figure 2 The limiting mechanism 5 includes a connecting box 51, a baffle 52, and a horizontal plate 53. The front and back ends of the top of the filling machine 1 are fixedly connected to the connecting box 51. The back end of the connecting box 51 is slidably connected to the baffle 52. The front end of the baffle 52 extends through the interior of the connecting box 51 and is fixedly connected to the horizontal plate 53. The left and right sides of the inner cavity of the connecting box 51 are both longitudinally fixedly connected to the positioning mechanism 6.

[0027] As a technical optimization of this utility model, the setting of the limiting mechanism 5 enables the horizontal plate 53 to move up and down under the influence of external force. The movement of the horizontal plate 53 drives the baffle 52 to move. When the baffle 52 moves to a low position, it can prevent the pallet 41 from moving beyond the specified distance. When the baffle 52 moves upward, it does not contact the pallet 41, allowing it to be transported out in conjunction with the conveying track 2. This achieves accurate determination of the position of the pallet 41 and avoids the accuracy of filling caused by incorrect movement of the pallet 41.

[0028] refer to Figure 3 The positioning mechanism 6 includes a frame 61, a slider 62, and a docking plate 63. The frame 61 is longitudinally fixedly connected to the left and right sides of the inner cavity of the connecting box 51. The slider 62 is slidably connected to the inner side of the frame 61. The docking plate 63 is fixedly connected to the inner side of the slider 62. The back end of the docking plate 63 is fixedly connected to the front end of the horizontal plate 53. The lifting assembly 7 is fixedly connected to the bottom of the inner wall of the connecting box 51.

[0029] As a technical optimization of this utility model, by setting the positioning mechanism 6, the docking plate 63 can be moved up and down under the influence of external force. The movement of the docking plate 63 drives the slider 62 to move stably inside the frame 61, so as to achieve horizontal stability of the movement of the docking plate 63 and avoid the wear of the machine caused by the deviation of the movement direction of the docking plate 63.

[0030] refer to Figure 3 The lifting assembly 7 includes an electric telescopic rod 71 and a fixing plate 72. The electric telescopic rod 71 is fixedly connected to the bottom of the inner wall of the connecting box 51, and the fixing plate 72 is fixedly sleeved on the top of the electric telescopic rod 71. The back end of the fixing plate 72 is fixedly connected to the front end of the docking plate 63.

[0031] As a technical optimization of this utility model, by setting up the lifting component 7, the electric telescopic rod 71 can drive the fixed plate 72 to move up and down. The movement of the fixed plate 72 controls the docking plate 63 to carry out mechanical power transmission, so as to realize the mutual cooperation and movement of mechanical parts, and avoid the phenomenon of breakage at the connection of the docking plate 63 due to excessive load when the fixed plate 72 moves.

[0032] refer to Figure 3 A slide rail 8 is provided on the surface of the frame 61 at the position corresponding to the slider 62, and the slide rail 8 is used in conjunction with the slider 62.

[0033] As a technical optimization of this utility model, the slide rail 8 can assist the slider 62 in working and also play a limiting role, preventing the slider 62 from detaching during movement.

[0034] refer to Figure 4 There are several hollow cylinders 42, which are evenly distributed and are used in conjunction with the tray 41.

[0035] As a technical optimization of this utility model, by setting the hollow cylinder 42, the load-bearing space of the tray 41 can be increased, thus avoiding the low working efficiency of a single hollow cylinder 42 and its inability to operate efficiently.

[0036] The working principle and usage process of this utility model are as follows: During use, the container is held and filled into the hollow cylinder 42 of the tray 41. Then, the tray 41 is placed on the conveyor track 2, and the conveyor track 2 of the filling machine 1 is started. The operation of the conveyor track 2 moves the tray 41 to the bottom of the screw feeder 3. Simultaneously, the electric telescopic rod 71 is activated while the conveyor track 2 is in operation. The electric telescopic rod 71 moves downward, causing the fixed plate 72 to move. The downward movement of the fixed plate 72 causes the docking plate 63 to move accordingly. The downward movement of the docking plate 63 causes the slider 62 to move stably along the slide rail 8 inside the frame 61. The movement of the slider 62 causes the docking plate 63 and the horizontal plate 53 to move synchronously. The movement of the horizontal plate 53 causes the baffle 52 to move downward. When pallets 41 are placed on conveyor track 2 at inconsistent positions, they are conveyed at the same distance and first contact baffle 52 to prevent further movement, thus stopping pallets 41 accurately at the bottom of screw feeder 3. Finally, the container touches the bottom inside hollow cylinder 42 and contacts weighing sensor 43. Weighing sensor 43 measures the weight of the material in real time and transmits the electrical signal to controller 44. Controller 44 starts screw feeder 3 to accurately add material according to the set weight value, thereby achieving accurate metering and filling. Then, electric telescopic rod 71 is activated to move upward, driving baffle 52 to move upward without contacting pallet 41, and working with conveyor track 2 to transport pallet 41 out and remove the container, so that pallet 41 can be reused for processing.

[0037] In summary, this automatic metering and feeding machine for paint production works in conjunction with a filling machine 1, a conveying track 2, a screw feeder 3, a metering mechanism 4, a tray 41, a hollow cylinder 42, a weighing sensor 43, a controller 44, and a limit mechanism 5. During operation, the container is filled into the hollow cylinder 42 of the tray 41. Then, the conveying track 2 of the filling machine 1 is activated, transporting the tray 41 to the bottom of the screw feeder 3. The container contacts the weighing sensor 43 at the bottom, which measures the weight of the material in real time and transmits an electrical signal to the controller 44. The controller 44 then activates the screw feeder 3 to precisely add material according to the set weight value, thus achieving accurate metering and filling. This avoids excessive output from the screw feeder 3, preventing resource waste and solving the problem that metering accuracy is crucial in existing feeding machines when filling paint, where excessive feeding leads to waste, while insufficient feeding fails to meet the standard value.
