Description

Technical Field

[0001] The utility model relates to the technical field of coating production, in particular to an intermittent feeding device for coating raw materials. Background Art

[0002] Paint is a chemical mixture material that can firmly cover the surface of an object for protection, decoration, marking and other special purposes. It is often used in construction or industrial fields.

[0003] In the existing patent literature, there is a patent with the publication number CN 213923143 U, entitled "A feeding device for industrial coating raw materials". This patent can achieve continuous feeding through feeding tubes, screws and other structures. However, in actual application, although continuous feeding can improve feeding efficiency, it is not conducive to the rapid dissolution of raw materials during subsequent stirring. This will increase the stirring and dissolving time and greatly extend the overall processing time, resulting in low overall processing efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an intermittent feeding device for coating raw materials. When the driving barrel is driven to rotate by the motor, the feeler rod will be pushed upward when passing through the resistance bump, and the material port will be opened. Then the material control valve core will rebound and reset under the action of the spring, so as to perform intermittent feeding. Since there is a certain time difference in each feeding, it can ensure that the raw materials are fully dissolved in the stirring kettle, so that the overall processing efficiency will be higher.

[0005] In order to solve the above technical problems, the technical solution of the present utility model is achieved as follows:

[0006] An intermittent feeding device for coating raw materials comprises an internally hollow storage box, the bottom of which is docked with the feeding box; a horizontally arranged motor is fixedly installed in the feeding box, a driving barrel is concentrically docked with the rotating shaft of the motor, and an interference protrusion is fixedly installed on the outer wall of the driving barrel; a feeding port is provided between the storage box and the feeding box, a material control valve core is movably installed at the feeding port and can completely block the feeding port; a vertically arranged touch rod is fixed to the bottom of the material control valve core, a push piece is fixedly installed on the rod body of the touch rod, the push piece is slidably installed on a guide rod fixed around the feeding port, and the guide rod is provided with a spring that pushes the push piece to slide downward.

[0007] With the above solution, when the driving barrel is driven to rotate by the motor, the feeler rod will be pushed upward when it passes through the resistance bump, and the material port will open. Then the material control valve core will rebound and reset under the action of the spring, so as to perform intermittent material discharge. Since there is a certain time difference between each discharge, it can ensure that the raw materials are fully dissolved in the stirring kettle, making the overall processing efficiency higher.

[0008] As a preferred embodiment of an intermittent feeding device for coating raw materials, the top shape of the material control valve core is like a "wok lid", and the bottom shape of the material control valve core is like a "wok bottom"; when the material control valve core is pushed to open the material port, the raw materials in the storage box fall toward the location of the touch rod.

[0009] By adopting the above scheme, in order to ensure that the material port can be blocked by the material control valve core, the bottom shape of the material control valve core is designed to be a "wok bottom". The bottom of the material control valve core can completely match the material port, thereby achieving the blocking of the material port.

[0010] As a preferred embodiment of the intermittent feeding device for coating raw materials, the lower end of the contact rod and the middle end of the abutting protrusion are both round heads.

[0011] By adopting the above solution, in order to reduce the wear between the touch rod and the abutting bump, the contacting ends of the two are designed to be rounded, which reduces the friction force when the two are in contact, thereby extending the service life of the two.

[0012] As a preferred embodiment of an intermittent feeding device for coating raw materials, an inclined offset plate is fixed at the feeding port below the feeding box, and the offset plate is located directly below the driving barrel.

[0013] With the above solution, in order to facilitate the guidance of the raw materials during feeding, an offset material plate is installed to facilitate the feeding of the raw materials to a specific position.

[0014] As a preferred embodiment of the intermittent feeding device for coating raw materials, a detachable box cover is fixedly connected to the top of the storage box.

[0015] With the above solution, in order to facilitate the feeding of raw materials into the storage box, the box cover can be removed to pour the raw materials into the storage box.

[0016] As a preferred embodiment of an intermittent feeding device for coating raw materials, an L-shaped suspension arm is fixedly installed at the bottom of the feeding box, and the intermittent feeding device for coating raw materials is suspended and fixed directly above the coating raw material stirring kettle by the L-shaped suspension arm.

[0017] With the above solution, in order to facilitate the overall fixation of the intermittent feeding device for the coating raw materials, an L-shaped suspension arm is fixed in the air directly above the coating raw material stirring kettle, thereby not occupying space on the ground.

[0018] As a preferred embodiment of the intermittent feeding device for coating raw materials, both sides of the abutting protrusion are inclined slopes, and the slopes are planes or upward convex curved surfaces or downward concave curved surfaces.

[0019] By adopting the above scheme, in order to ensure that the material control valve core can be more smooth when rising or falling, the two sides of the contact block are flat or convex or concave curved slopes. Then, when the slope contacts the lower end of the contact rod, it will rise or fall relatively smoothly, which will make the material control valve core smoother when rising or falling.

[0020] After adopting the above technical solution, the beneficial effects of the utility model are:

[0021] 1. When the driving barrel is driven by the motor to rotate, the feeler rod will be pushed upward when it passes the bump, and the material port will open. Then the material control valve core will rebound and reset under the action of the spring, so as to perform intermittent material discharge. Since there is a certain time difference between each discharge, it can ensure that the raw materials are fully dissolved in the stirring kettle, making the overall processing efficiency higher;

[0022] 2. In order to ensure that the material port can be blocked by the material control valve core, the bottom shape of the material control valve core is designed to be a "wok bottom". The bottom of the material control valve core can completely match the material port, thereby achieving the blocking of the material port;

[0023] 3. In order to reduce the wear between the contact rod and the contact bump, the contact ends of the two are designed to be rounded. The friction between the two will be smaller during contact, thereby extending the service life of the two.

[0024] 4. In order to ensure that the material control valve core can be more smooth when rising or falling, the two sides of the contact block are flat or convex or concave curved slopes. Then, when the slope contacts the lower end of the contact rod, it will rise or fall relatively smoothly, making the material control valve core more smooth when rising or falling.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Example 1, as Figures 1 to 8As shown, an intermittent feeding device for coating raw materials is used for feeding coating raw materials into a coating raw material stirring kettle, which includes an internal hollow storage box 1, and a feeding box 2 is installed at the bottom of the storage box 1; a horizontally arranged motor 3 is fixedly installed in the feeding box 2, and a driving barrel 4 is concentrically docked on the rotating shaft of the motor 3, and a resistance protrusion 5 is fixedly installed on the outer wall of the driving barrel 4, wherein the two sides of the resistance protrusion 5 are inclined slopes, and the slope is flat; a feeding port is opened between the storage box 1 and the feeding box 2, and a material control valve core 6 that can completely block the feeding port is movably installed at the feeding port; a vertically arranged touch rod 7 is fixed to the bottom of the material control valve core 6, and a push piece 8 is fixedly installed on the rod body of the touch rod 7, and the push piece 8 is slidably installed on a guide rod 9 fixed around the material port, and the guide rod 9 is provided with a spring 10 that pushes the push piece 8 to slide downward. When the driving barrel 4 is driven to rotate by the motor 3, the feeler rod 7 will be pushed upward when it passes the abutment protrusion 5. At this time, the material port will be opened, and then the material control valve core 6 will rebound and reset under the action of the spring 10, so as to perform intermittent material discharge. Since there is a certain time difference between each discharge, it can ensure that the raw materials are fully dissolved in the stirring kettle, so that the overall processing efficiency will be higher.

[0039] like Figure 6 As shown, the top of the material control valve core 6 is shaped like a "wok lid," and the bottom of the material control valve core 6 is shaped like a "wok bottom." When the material control valve core 6 is pushed to open the material opening, the material in the material storage box 1 falls toward the location of the contact rod 7. To ensure that the material opening is blocked by the material control valve core 6, the bottom of the material control valve core 6 is designed to be shaped like a "wok bottom." The bottom of the material control valve core 6 can completely match the material opening, thereby achieving sealing of the material opening.

[0040] like Figure 6 As shown, the lower end of the feeler rod 7 and the middle end of the abutting protrusion 5 are both rounded. In order to reduce wear between the feeler rod 7 and the abutting protrusion 5, the contacting ends of the two are both designed to be rounded, which reduces the friction between the two during contact and thus prolongs the service life of the two.

[0041] like Figure 7 As shown, a tilted offset plate 11 is fixed at the feeding port below the feeding box 2, and the offset plate 11 is located directly below the driving barrel 4. In order to facilitate the guidance of the raw materials during feeding, a bias plate 11 is installed to facilitate the feeding of the raw materials to a specific position.

[0042] like Figure 3 Shown, the top of the storage box 1 is fixed with a detachable box cover 12. For convenience in the storage box 1, raw materials are placed, and the detachable box cover 12 is poured into the storage box 1.

[0043] like Figure 4As shown, an L-shaped suspension arm 13 is fixedly mounted on the bottom of the feeding box 2. The intermittent feeding device for the coating raw material is suspended and fixed directly above the coating raw material mixing kettle via the L-shaped suspension arm 13. In order to facilitate the overall fixation of the intermittent feeding device for the coating raw material, the L-shaped suspension arm 13 is suspended and fixed directly above the coating raw material mixing kettle so as not to occupy space on the ground.

[0044] Example 2, as Figure 9 As shown, the only difference between this embodiment and the first embodiment is that the two sides of the contact protrusion 5 are inclined slopes, and the slopes are upward convex curved surfaces. The planes on both sides of the contact protrusion 5 are replaced by upward convex curved slopes. Then, when the slopes contact the lower end of the contact rod 7, they can still rise or fall relatively smoothly, and the effect achieved is basically the same as that of the first embodiment.

[0045] Example 3, as Figure 10 As shown, the difference between this embodiment and embodiment one and embodiment two is that: the two sides of the contact protrusion 5 are inclined slopes, and the slopes are concave curved surfaces. The flat surfaces and convex curved surfaces on both sides of the contact protrusion 5 are replaced with concave curved slopes. Then, when the slopes contact the lower end of the contact rod 7, they can still rise or fall relatively smoothly. The effect achieved is basically the same as that of embodiment one and embodiment two.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
