Description

Technical Field

[0001] The invention belongs to the technical field of carbon black blanking, and in particular relates to a high-efficiency blanking device for ton bags of carbon black. Background Art

[0002] Carbon black, also known as carbon black, is a black powdered amorphous carbon. Carbon black is mainly used as a rubber reinforcing agent and is used in the manufacture of automobile tires. It is also used as a pigment, a conductive agent for dry batteries, a catalyst carrier, and a super-hard alloy material. Carbon black is stored in ton bags. When the ton bags filled with carbon black need to be unloaded, because there is a lot of carbon black stored and the gravity is large, a feeding device is needed to assist in unloading the ton bags of carbon black, making it more convenient to unload the ton bags of carbon black.

[0003] According to a special unloading device for ton bags of carbon black with patent number CN214690614U, it includes a material box, the outer surface of the material box is provided with an opening piece, the opening piece includes two limit plates, two transmission discs and two protrusions, the two limit plates are fixedly connected to the lower surfaces of the front and rear sides of the material box, respectively, the two transmission discs are rotatably connected to the front and rear surfaces of the material box, and the two protrusions are fixedly connected to the front and rear side surfaces of the material box, respectively; the device is clamped with a clamping ring at the middle position of the outer surface of the fixing rod, and the upper surface of the clamping ring is fixedly connected with a scraper. When unloading the carbon black in the ton bag, the ton bag is first placed in the material box, and then the servo motor can drive the scraper to move, so that the scraper can cut a long cut on the lower surface of the ton bag, so that the carbon black in the ton bag can fall down quickly, thereby improving the unloading speed of the carbon black in the ton bag.

[0004] In the process of realizing the present invention, the applicant found that there are at least the following problems: during the opening and unloading of carbon black from the ton bag, due to the large amount of material in the ton bag, the ton bag will move downward due to the carbon black, and the relatively concentrated unloading of carbon black may also cause uneven force distribution in the ton bag, making the bottom of the ton bag more prone to wrinkles or deformation, etc., making the opening position smaller, resulting in congestion in the unloading of carbon black, affecting the unloading; and after the carbon black is unloaded from the ton bag, carbon black sometimes remains on the inner wall. This is due to the friction between the carbon black particles and the inner wall or the static electricity during the unloading process, resulting in incomplete unloading and waste of carbon black. In addition, the carbon black remaining on the inner wall will affect the reuse and cleaning effect of the ton bag. Summary of the invention

[0005] The object of the present invention is to provide a high-efficiency unloading device for ton bags of carbon black, so as to solve the problems of the ton bag carbon black unloading device proposed in the above background technology.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A highly efficient unloading device for ton bags of carbon black, comprising:

[0008] The material box is the main body of this high-efficiency unloading device for ton bags of carbon black;

[0009] A discharge chute, which is opened in the middle of the bottom of the material box;

[0010] Carbon black ton bags, which are placed inside the material box;

[0011] A limit assembly, which is arranged above both sides of the material box;

[0012] A slitting assembly, which is disposed at the lower interior of the material box;

[0013] The anti-residue components are arranged on both sides of the interior of the material box.

[0014] Preferably, the limiting component further includes:

[0015] A first adjustment plate, which is arranged above both sides of the material box;

[0016] A first electric push rod, which is arranged on the inner side of the first adjustment plate and connected to the material box;

[0017] A top support plate, which is fixedly arranged in the middle of one side of the first adjustment plate and penetrates into the interior of the material box;

[0018] A limiting roller is rotatably arranged at one end of the top supporting plate.

[0019] Preferably, the slitting assembly further comprises:

[0020] A rotating roller, which is rotatably arranged at the lower part of the material box via a rotating shaft;

[0021] A conical cutter, which is fixedly arranged on the top of the rotating roller;

[0022] Support rollers are rotatably arranged on both sides of the bottom of the rotating roller.

[0023] Preferably, the anti-residue component further includes:

[0024] Elastic guide plates, which are arranged on both sides of the interior of the material box;

[0025] A connecting rope, which is arranged in the middle of the bottom of the elastic guide plate;

[0026] A second adjustment plate, which is arranged below both sides of the material box;

[0027] A second electric push rod is arranged on the inner side of the second adjustment plate and connected to the material box.

[0028] Preferably, the top support plate is slidably connected to the side wall of the material box, and the outer surface of the limiting roller is in contact with the carbon black ton bag.

[0029] Preferably, one end of the rotating shaft away from the rotating roller extends to the outer surface of the material box and is fixedly provided with an anti-skid rotating handle.

[0030] Preferably, the distance between the two support rollers is greater than the width of the conical cutter, and the length of the conical cutter matches the inner width of the material box.

[0031] Preferably, one end of the connecting rope away from the elastic guide plate passes through the outside of the material box and is connected to the second adjustment plate.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] By setting the limit assembly, the first electric push rod can drive the first adjustment plate to move inward, and the limit rollers can clamp the two sides of the carbon black ton bag through the top support plate to prevent the carbon black ton bag from moving downward during the unloading process and causing wrinkles or deformation at the bottom of the ton bag. In this way, the position of the carbon black ton bag can be stabilized by clamping the limit rollers, which is conducive to unloading control and ensures the accuracy and reliability of the unloading amount;

[0034] By setting up the slitting assembly, the roller can be rotated through the rotating shaft during the falling process of the carbon black ton bag. Due to the downward squeezing force of the carbon black ton bag, the rotating cone knife can cut the bottom of the carbon black ton bag so that the carbon black ton bag can be unloaded. After the roller is rotated again, the two support rollers can be supported on both sides of the opening of the carbon black ton bag respectively, so that the carbon black can fall more smoothly; it can ensure that the bottom will not encounter resistance while the carbon black in the carbon black ton bag falls, and the appearance of the support roller can also stabilize the carbon black ton bag and promote the smooth falling of the carbon black, further improving the unloading efficiency and accuracy;

[0035] By setting up an anti-residue component, when removing residual carbon black, the second electric push rod drives the second adjustment plate to move outward, thereby pulling the elastic guide plate inward through the connecting rope. After that, the second electric push rod drives the second adjustment plate to retract and release the connecting rope. The elastic guide plate bounces outward under the action of its own elastic force, thereby vibrating the residual carbon black outward and shaking it off. This means that during the operation of the equipment, if it is necessary to clean the residual carbon black material, the anti-residue component can complete the task quickly.

The conditions in the examples can be further adjusted according to specific conditions. Simple improvements to the method of the present invention under the premise of the concept of the present invention belong to the scope of protection claimed in the present invention.

[0044] Example 1: Please refer to Figure 1 and 2 The present invention provides an efficient unloading device for ton bags of carbon black, comprising a material box 1 for placing ton bags of carbon black 8 so that the carbon black in the ton bags of carbon black 8 can be unloaded in the material box 1; a discharging trough 2 is arranged in the middle of the bottom of the material box 1, so that the unloaded carbon black can be discharged through the discharging trough 2; a limiting component 5 is arranged above both sides of the material box 1, and can limit both sides of the carbon black ton bag 8, so that the unloading process of the carbon black ton bag 8 is more stable; a slitting component 6 is arranged at the lower part of the material box 1, and can cut an opening at the bottom of the carbon black ton bag 8 for unloading carbon black; an anti-residue component 7 is arranged on both sides of the material box 1, and can clear out the residual carbon black through elastic vibration; so that the unloading process of the ton bag carbon black is not easy to be congested or residual, so that the utilization of carbon black is more comprehensive and efficient;

[0045] Specifically, Figure 5 As shown, the limiting assembly 5 pre-processes the carbon black ton bag 8 to ensure smooth unloading; after the carbon black ton bag 8 is placed in the material box 1, the operation of the first electric push rod 502 can drive the first adjustment plate 501 inward, thereby pushing the limiting roller 504 to clamp the two sides of the carbon black ton bag 8 through the supporting plate 503, so that the position of the carbon black ton bag 8 can be stabilized;

[0046] Specifically, Figure 2 and 3As shown, the slitting assembly 6 can rotate the roller 601 through the rotating shaft 602 during the falling process of the carbon black ton bag 8. Due to the downward squeezing force of the carbon black ton bag 8, the rotating cone knife 603 can cut the bottom of the carbon black ton bag 8; the roller 601 can be turned over by rotating the rotating shaft 602; after the roller 601 is turned over, it will also drive the cone knife 603 and the support roller 604, so that after the roller 601 rotates again, the two support rollers 604 can be supported on both sides of the opening of the carbon black ton bag 8, so that the carbon black can fall more smoothly;

[0047] Specifically, Figure 4 As shown, the anti-residue component 7, through the design of the elastic guide plate 701, can vibrate the residual material outward, thereby ensuring the normal operation of the equipment and avoiding unnecessary failures and losses; the second adjustment plate 703 and the second electric push rod 704, the second electric push rod 704 drives the second adjustment plate 703 to move outward; the connecting rope 702 and the elastic guide plate 701, through the connecting rope 702, pull the elastic guide plate 701 inward; after that, the second electric push rod 704 drives the second adjustment plate 703 to retract and release the connecting rope 702, and the elastic guide plate 701 bounces outward under the action of its own elastic force, so that the residual carbon black can be vibrated outward, and the residual carbon black material can be quickly cleaned up.

[0048] Example 2: Please refer to Figure 1 and 2 The present invention provides a highly efficient unloading device for ton bags of carbon black, comprising an observation window 3 and an operating table 4 respectively arranged on the outer surface of a material box 1, the operating table 4 being electrically connected to a first electric push rod 502 and a second electric push rod 704 respectively, so that the first electric push rod 502 and the second electric push rod 704 can be controlled to open and close respectively by using the operating table 4;

[0049] Specifically, Figure 5 As shown, it includes: the outer surface of the limiting roller 504 is rough and made of rubber, so that when the limiting roller 504 is attached to the carbon black ton bag 8, the carbon black ton bag 8 can be clamped and limited and avoid wear on it;

[0050] Specifically, Figure 2 and 3 As shown, the roller 601 is also located above the discharge chute 2, so when the discharge chute 2 is congested, rotating the roller 601 can play a role in clearing the blockage and prevent inconvenience caused by blockage;

[0051] Specifically, Figure 4As shown, it includes: a guide pulley is arranged in the middle of the outer surface of the connecting rope 702, and the connecting rope 702 will be guided by it after passing through the guide pulley, so that after the connecting rope 702 is pulled, the force direction of the elastic guide plate 701 will be more concentrated in the middle of the bottom, so that the elastic guide plate 701 is pulled inward, and then after the connecting rope 702 is relaxed, the elastic guide plate 701 bounces outward under the action of its own elastic force, so that the residual carbon black can be shaken off.

[0052] Working principle: First, place the carbon black ton bag 8 in the material box 1, and then the first electric push rod 502 in the limiting component 5 can drive the first adjustment plate 501 to move inward, and the limiting roller 504 is clamped on both sides of the carbon black ton bag 8 through the top support plate 503; then the rotating shaft 602 in the slitting component 6 rotates the rotating roller 601, and due to the downward squeezing force of the carbon black ton bag 8, the rotating cone knife 603 can cut the bottom of the carbon black ton bag 8, so that the carbon black ton bag 8 can be unloaded, and after the rotating roller 601 is rotated again, the two supporting rollers 604 can be separated. They are supported on both sides of the opening of the carbon black bag 8, which can stabilize the carbon black bag 8 and promote the smooth falling of the carbon black. Then, when removing the residual carbon black, the second electric push rod 704 in the anti-residue component 7 drives the second adjustment plate 703 to move outward, thereby pulling the elastic guide plate 701 inward through the connecting rope 702. After that, the second electric push rod 704 drives the second adjustment plate 703 to retract and release the connecting rope 702. The elastic guide plate 701 bounces outward under the action of its own elastic force, thereby vibrating the residual carbon black outward and shaking it off.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
