Description

Technical Field

[0001] The invention belongs to the technical field of powder material delivery devices, in particular to a powder material delivery device for color paste production. Background Art

[0002] Pigment paste dispersed by adding surfactants to water as a medium is called water-based color paste. Water-based color paste is used for coloring and has a wide range of applications, including coatings, leather, printing, papermaking, latex, textiles and other industries. In the production process of water-based color paste, some powdered raw materials need to be put into the tank body, so that the powdered raw materials and the liquid in the tank body are stirred and mixed, and finally the water-based color paste is formed;

[0003] Nowadays, when powdered raw materials are put into the tank, there is no function of quantitative feeding of powder. Most of the time, the staff puts the powder into the mixing tank at one time for mixing. Such a one-time feeding will cause the color paste to form slowly and the mixing to be uneven, which will cause lump-like color paste to appear inside, thereby reducing the mixing efficiency. Summary of the invention

[0004] In order to solve the problem that a powder feeding device for color paste production is proposed in the above background technology, one-time feeding will lead to slow color paste formation and uneven mixing, which will cause lump-like color paste to appear inside, thereby reducing the mixing efficiency.

[0005] To achieve the above object, the present invention provides the following technical solution: comprising:

[0006] The main body component includes a delivery bucket, a shielding component rotatably connected to the outside of the delivery bucket, and a knocking component fixedly connected to the shielding component;

[0007] The control component comprises a resistance component rotatably connected to the outside of the delivery bucket, a guide component movably connected inside the resistance component, and a counterweight component fixedly connected to the outside of the resistance component.

[0008] Preferably, the shielding assembly includes a support plate fixedly connected to the outside of the delivery bucket, a shaft rod rotatably connected to the end of the support plate, and a baffle rotatably connected to the end of the shaft rod.

[0009] Preferably, a knocking groove is provided on the inner wall of the baffle;

[0010] The knocking assembly includes a receiving rod fixedly connected to the support plate, a cavity opened inside the receiving rod, a knocking rod slidably connected in the cavity, and an elastic member arranged between the end of the knocking rod and the inner wall of the cavity.

[0011] Preferably, the interference assembly includes a support rod rotatably connected to the outside of the delivery bucket, an output rod fixedly connected to the outside of the support rod, an output block rotatably connected to the end of the output rod, and a limiting groove opened on the output block.

[0012] Preferably, the guide assembly includes a notch plate fixedly connected to the end of the shaft rod, an inclined plate fixedly connected to the end of the notch plate, and a limiting rod fixedly connected to the end of the inclined plate.

[0013] Preferably, the counterweight assembly includes an output block fixedly connected to the outside of the support rod, a counterweight groove opened on the output block, an L-shaped slide groove opened at the bottom of the output block, a limit groove opened at the end of the output block, and a counterweight block arranged in the counterweight groove.

[0014] Preferably, it also includes a fixing component;

[0015] It comprises a trigger component arranged in the counterweight component, a fixing component movably connected in the counterweight component, and a plug-in component slidably connected in the counterweight component.

[0016] Preferably, the trigger assembly includes a trigger rod movably connected in the counterweight slot, a connecting plate slidably connected to the outside of the trigger rod, and a slot provided on the connecting plate.

[0017] Preferably, the fixing assembly includes a transmission rod fixedly connected to the end of the connecting plate, and a fixing plate fixedly connected to the end of the transmission rod.

[0018] Preferably, the plug-in assembly includes a slider slidably connected to the limiting groove, an insertion rod fixedly connected to the end of the slider, and a force storage member provided between the slider and the limiting groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: first, an object of a specified weight is placed in the counterweight component, and then the powder is placed on the shielding component through the delivery hopper. When the weight on the shielding component is greater than the weight placed in the counterweight component, the resistance component will rotate with itself as the center of the circle, and at the same time drive the guide component to rotate with the shielding component as the center of the circle. At this time, the guide component can resist the resistance component to lift the counterweight component. When the internal material is unloaded, the counterweight component will be reset under the action of gravity, and at the same time drive the shielding component to shield the port of the discharge hopper, thereby achieving the purpose of quantitative powder delivery of the discharge hopper;

[0020] Place the counterweight block in the counterweight slot, and the trigger assembly will slide downward due to the weight of the counterweight block. At this time, the trigger assembly will drive the fixed assembly to move toward the counterweight block and fix the counterweight block. During the movement of the fixed assembly, it will also resist the plug-in assembly. When the fixed assembly completely fixes the counterweight block, the plug-in assembly will be inserted into the fixed assembly and restrain the fixed assembly. At this time, the purpose of facilitating the replacement of the counterweight block is achieved, which can further achieve the purpose of facilitating the quantitative measurement of the material being discharged.

DETAILED DESCRIPTION

[0030] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0031] Example 1, reference Figure 1 to Figure 3 As shown in the figure, it is the first embodiment of the present invention, which provides a powder delivery device for color paste production, including a main body component 100, including a delivery bucket 101, a shielding component 102 rotatably connected to the outside of the delivery bucket 101, and a knocking component 103 fixedly connected to the shielding component 102; a control component 200, including a resistance component 201 rotatably connected to the outside of the delivery bucket 101, a guide component 202 movably connected to the inside of the resistance component 201, and a counterweight component 203 fixedly connected to the outside of the resistance component 201. First, a specified weight is placed in the counterweight component 203. The items are then dropped into the shielding component 102 through the dropping hopper 101. When the weight on the shielding component 102 is greater than the weight placed in the counterweight component 203, the resistance component 201 will rotate with itself as the center of the circle, and at the same time drive the guide component 202 to rotate with the shielding component 102 as the center of the circle. At this time, the guide component 202 can resist the resistance component 201 to lift the counterweight component 203. When the internal material is unloaded, the counterweight component 203 will be reset under the action of gravity, and at the same time drive the shielding component 102 to block the port of the discharge hopper, thereby achieving the purpose of quantitative powder delivery of the discharge hopper.

[0032] Example 2, reference Figure 1 to Figure 6 , which is the second embodiment of the present invention. Different from the previous embodiment, the shielding assembly 102 includes a support plate 102a fixedly connected to the outside of the delivery bucket 101, a shaft 102b rotatably connected to the end of the support plate 102a, and a baffle 102c rotatably connected to the end of the shaft 102b. A pair of support plates 102a are fixedly connected to the side of the delivery bucket 101, and the ends of the pair of support plates 102a are rotatably connected to the shaft 102b. The ends of the shaft 102b are commonly fixedly connected to the baffle 102c. The baffle 102c shields the end of the delivery bucket 101, and the baffle 102c is opened to feed materials by controlling the rotation of the shaft 102b.

[0033] Furthermore, a knocking groove 102d is provided on the inner wall of the baffle 102c; the knocking assembly 103 includes a accommodating rod 103a fixedly connected to the support plate 102a, a cavity 103b provided inside the accommodating rod 103a, a knocking rod 103c slidably connected in the cavity 103b, and an elastic member 103d provided between the end of the knocking rod 103c and the inner wall of the cavity 103b, a knocking groove 102d is provided on the inner wall of the baffle 102c, the knocking groove 102d is arranged in an arc-shaped wavy shape, and is uneven, the accommodating rod 103a is fixedly connected to the support plate 102a, and a cavity 103b is provided inside the accommodating rod 103a, and the knocking rod 103c is slidably connected inside the cavity 103b, and the end of the knocking rod 103c is An elastic member 103d is provided between the part and the cavity 103b, and the other end of the knocking rod 103c passes through the cavity 103b and is movably connected in the knocking groove 102d, so that the knocking rod 103c is driven to slide in the knocking groove 102d during the rotation of the above-mentioned shaft rod 102b. During this process, the knocking rod 103c will slide into the cavity 103b at the raised part of the knocking groove 102d, and at the same time squeeze the elastic member 103d. When the knocking rod 103c enters the recessed position, the elastic member 103d will push the knocking rod 103c into the recessed position, and at the same time hit the baffle 102c. The vibration generated in this way can prevent the powder from adhering to the baffle 102c, so that the powder put in is greatly different from the expected one.

[0034] Further, the resistance assembly 201 includes a support rod 201a rotatably connected to the outside of the delivery bucket 101, an output rod 201b fixedly connected to the outside of the support rod 201a, an output block 203a rotatably connected to the end of the output rod 201b, and a limiting groove 201d provided on the output block 203a. The guide assembly 202 includes a notch plate 202a fixedly connected to the end of the shaft rod 102b, an inclined plate 202b fixedly connected to the end of the notch plate 202a, and a limiting rod 202c fixedly connected to the end of the inclined plate 202b. The side of the delivery bucket 101 is rotatably connected to the support rod 201a, the side of the end of the support rod is fixedly connected to the output rod 201b, and the end of the output rod 201b is fixedly connected to the movable block 201c. A limiting groove 201d is provided on the outer side of the movable part, so that the support rod 201a can drive the output rod 201b and the movable block 201c to rotate with the support rod 201a as the center during the rotation. The end of the shaft rod 102b on one side passes through the inner wall of the baffle 102c and is fixedly connected with the notch plate 202a. The end of the notch plate 202a is fixedly connected with the inclined plate 202b. The ends of the notch plate 202a and the inclined plate 202b are both fixedly connected with limiting blocks. In this way, the output rod 201b and the movable block 201c can contact the inner walls of the inclined plate 202b and the notch plate 202a when rotating, thereby driving the shaft rod 102b and the baffle 102c to rotate. At this time, the material on the baffle 102c will be discharged, thereby achieving the purpose of quantitative unloading.

[0035] Furthermore, the counterweight assembly 203 includes an output block 203a fixedly connected to the outside of the support rod 201a, a counterweight groove 203b provided on the output block 203a, an L-shaped slide groove 203c provided at the bottom of the output block 203a, a limit groove 203d provided at the end of the output block 203a, and a counterweight block 203e provided in the counterweight groove 203b. The output block 203a is fixedly connected to the outside of the support rod 201a, and a counterweight groove 203b is provided on the top of the output block 203a. An L-shaped chute 203c is provided at the bottom of the block 203a, and the vertical groove part of the L-shaped chute 203c is opened into the output block 203a, and the horizontal groove part of the L-shaped chute 203c is opened at the bottom of the output block 203a. A limiting groove 203d is provided at the end of the output block 203a away from the support rod 201a, and a counterweight block 203e is arranged in the counterweight groove 203b. By placing counterweight blocks 203e of different weights in the counterweight groove 203b, quantitative control of the material on the baffle 102c can be achieved.

[0036] Working principle: When in use, first fix a designated counterweight block 203e in the counterweight groove 203b in the output block 203a, and then transport the material in the feeding hopper 101 to the baffle 102c. When the weight borne on the baffle 102c is greater than the weight of the counterweight block 203e, the baffle 102c will drive the shaft rod 102b to rotate and open with the shaft rod 102b as the center, and in the process of the rotation of the shaft rod 102b, the notched plate 202a, the inclined plate 202b and the limiting rod 202c will be driven to rotate with the shaft rod 102b as the center. At this time, the inner walls of the notched plate 202a and the inclined plate 202b will conflict with the limiting groove 201d of the movable block 201c, so that the movable block 201c and the output rod 201b rotate with the support rod 201a as the center, and at the same time, the movable block 201c will also drive the support rod 201a to rotate, and in the process of the rotation of the support rod 201a, the output block 2 03a and the counterweight 203e are tilted with the support rod 201a as the center, and the baffle 102c will be fully opened. At this time, the material will enter the mixing tank with a fixed weight. At this time, the weight loaded on the baffle 102c is less than the weight of the counterweight 203e. The output block 203a and the counterweight 203e will drive the support rod 201a to rotate under their own weight. At this time, the output rod 201b and the movable block 201c will rotate with the support rod 201a. During the rotation, they will contact the inner walls of the inclined plate 202b and the notched plate 202a through the limiting groove 201d, so that they drive the shaft rod 102b and the baffle 102c to rotate with the shaft rod 102b as the center. When the baffle 102c conflicts with the end of the feeding pipe 101b, the output block 203a and the counterweight 203e will no longer rotate with the support rod 201a as the center, thereby achieving the purpose of quantitative feeding.

[0037] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, it also includes a fixing component 300; it includes a trigger component 301 arranged in the counterweight component 203, a fixing component 302 movably connected in the counterweight component 203, and a plug-in component 303 slidably connected in the counterweight component 203. When the counterweight block 203e is placed in the counterweight slot 203b, the trigger component 301 will slide downward due to the weight of the counterweight block 203e. At this time, the trigger component 301 will drive the fixing component 302 to move toward the counterweight block 203e and fix the counterweight block 203e. In the process of moving the fixing component 302, it will also resist the plug-in component 303. When the fixing component 302 completely fixes the counterweight block 203e, the plug-in component 303 will be inserted into the fixing component 302 and restrain the fixing component 302. At this time, the purpose of facilitating the replacement of the counterweight block 203e is achieved, which can further achieve the purpose of convenient quantitative feeding.

[0038] Furthermore, the trigger assembly 301 includes a trigger rod 301a movably connected to the counterweight slot 203b, a connecting plate 301b slidably connected to the outside of the trigger rod 301a, and a slot 301c opened on the connecting plate 301b. The fixed assembly 302 includes a transmission rod 302a fixedly connected to the end of the connecting plate 301b, and a fixed plate 302b fixedly connected to the end of the transmission rod 302a. The counterweight slot 203b of the output block 203a is slidably connected with the trigger rod 301a. The trigger rod 301a is composed of a vertical rod and an oblique rod. The end of the trigger rod 301a is arranged in an arc shape, which can increase the contact area between the counterweight block 203e and the trigger rod 301a. The trigger rod 301a is located on the outside of the oblique rod and is slidably connected with a connecting plate 301b. The connecting plate 301b is slidably connected in the L-shaped slide groove 203c, and the vertical rod part of the connecting plate 301b is arranged in the vertical groove of the L-shaped slide groove 203c. At the same time, the side thereof is fixedly connected with a transmission rod 302a. The end of the transmission rod 302a passes through the vertical groove of the L-shaped slide groove 203c and is fixedly connected with a fixing plate 302b. In addition, the cross bar part of the connecting plate 301b is slidably connected in the cross groove of the L-shaped slide groove 203c, so that the trigger rod 301a can slide in the output block 203a. The end of the cross bar of the connecting plate 301b is provided with an inclined surface, and the connecting plate 301b is provided with a slot 301c above the cross bar.

[0039] When the counterweight block 203e is placed in the counterweight groove 203b, the counterweight block 203e can drive the trigger rod 301a to descend with its own weight. During the descent of the trigger rod 301a, its inclined rod part will slide inside the cross bar of the connecting plate 301b. Since the inclined rod is arranged in an inclined shape and the connecting plate 301b is slidably connected in the L-shaped slide groove 203c, the connecting plate 301b drives the transfer rod 302a and the fixed plate 302b to move toward the counterweight block 203e, and cooperates with the inner wall of the counterweight groove 203b to fix the counterweight block 203e, and then the connecting plate 301b can be restricted by the plug-in assembly 303, thereby achieving the purpose of facilitating the replacement of different counterweight blocks 203e.

[0040] Furthermore, the plug-in assembly 303 includes a slider 303a slidably connected in the limiting groove 203d, a plug rod 303b fixedly connected to the end of the slider 303a, and a force storage member 303c arranged between the slider 303a and the limiting groove 203d. The slider 303a is slidably connected inside the limiting groove 203d, and a force storage member 303c is arranged between the slide groove and the limiting groove 203d. The bottom end of the slider 303a located outside the limiting groove 203d is fixedly connected to the plug rod 303b, and the plug rod 303b matches the slot 301c. During the sliding process of the above-mentioned connecting plate 301b, its end will contact the plug rod 303b, so that the plug rod 303b drives the slider 303a slides upward in the limiting groove 203d and squeezes the force storage piece 303c. When the slot 301c on the connecting plate 301b moves to the position corresponding to the insertion rod 303b, the insertion rod 303b will not be affected by the resistance force of the connecting plate 301b. At this time, the force storage piece 303c will push the slider 303a to reset, and the insertion rod 303b will be inserted into the slot 301c, thereby locking the connecting plate 301b. When unlocking is required, the slider 303a is pushed upward to drive the insertion rod 303b to leave the slot 301c, thereby releasing the restriction on the connecting plate 301b, thereby achieving the purpose of facilitating the replacement of counterweight blocks 203e of different weights.

[0041] The rest of the structure is the same as that of Example 2.
