Description

Technical Field

[0001] This application relates to the field of color masterbatch technology, and more specifically, to an automatic feeding device for color masterbatch production. Background Technology

[0002] Color masterbatch is mainly composed of three basic elements: pigments or dyes, carrier resin (or carrier), and additives. The production process of color masterbatch usually includes steps such as batching, premixing, melting, extrusion, cooling, and pelletizing. In this process, pigments or dyes are mixed evenly with carrier resin and additives and processed into granules through special processes. Automatic feeding of color masterbatch raw materials is required during processing. Currently, there are various automatic feeding devices for color masterbatch on the market to achieve this purpose.

[0003] In related technologies, in order to reduce dust generated during the pouring and feeding of color masterbatch raw materials, for example, the prior art patent with publication number CN221677753U provides an automatic feeding mechanism for color masterbatch processing. This device uses a vibrating grid driven by a vibrating motor to eventually fall down. During the material passage, a fan works to suck in the dust generated by the pouring at the feed inlet. The sucked-in dust falls into the return pipe after passing through the fan and eventually merges with the naturally sliding material.

[0004] Although the existing technical solutions mentioned above have achieved the effect of reducing dust during the raw material feeding process by using a fan to suck in and recover the material that is raised, the impurities mixed in during the processing, transportation or storage of the raw materials may interfere with the production process of color masterbatch, resulting in uneven dispersion of color masterbatch, and may even cause wear or damage to the internal parts of the equipment.

[0005] In view of this, we propose an automatic feeding device for color masterbatch production. Utility Model Content

[0006] The purpose of this application is to provide an automatic feeding device for color masterbatch production, which can effectively solve the problem that impurities mixed in with raw materials may interfere with the color masterbatch production process in the prior art.

[0007] This application provides an automatic feeding device for color masterbatch production, including:

[0008] A feeding hopper, the bottom of which is connected to a pipe, and discharge holes are provided on both sides of the pipe;

[0009] The filter element is disposed through the inner cavity of the pipe. The filter element includes a rotatable filter screen located in the inner cavity of the pipe. A fixing frame that is synchronously linked with the filter screen is also provided on the outside of the feeding hopper.

[0010] A driving component and a blocking component are disposed on the outside of the pipe. The driving component includes a rotatable connecting rod and a protruding post, one end of which is movably connected to a fixed frame.

[0011] As an optional solution to the technical solution of this application, the filter element further includes a rotating rod rotatably connected to the inner cavity of the pipe. The filter screen is fixedly connected to the rotating rod, and the rotating rod is located at the central axis of the filter screen, which is used to filter the color masterbatch raw material to separate larger particles.

[0012] As an optional solution to the technical solution in this application, the two side walls of the pipe are set as arc surfaces, and the curvature of the arc surfaces is adapted to the rotation path of the filter screen.

[0013] As an optional solution to the technical solution of this application, one end of the rotating rod extends movably through to the outside of the pipe, and the fixing frame is fixedly connected to the outer end of the rotating rod.

[0014] As an optional solution to the technical solution of this application, the driving component includes a mounting bracket fixedly connected to the outside of the pipe, a driving part fixedly mounted on the top of the mounting bracket, the driving part being a stepper motor, one side of the connecting rod being drivenly connected to the output shaft of the driving part, and the protruding post being fixedly connected to one side of the connecting rod for reciprocating rotation of the filter screen to achieve screening, and can be rotated to an inclined state to discharge impurities.

[0015] As an optional solution to the technical solution of this application, the shielding component includes shielding plates located outside the two discharge holes. The shielding plates are adapted to the arc surfaces on both sides of the pipe. Ear plates are fixedly connected to both sides of the shielding plates. Two symmetrically distributed sliding grooves are opened on the other two sides of the pipe. The inner cavity of the sliding grooves allows the ear plates at the corresponding positions to slide, which is used to shield the discharge holes and prevent raw materials from falling.

[0016] As an optional solution to the technical solution of this application, a fixing block is fixedly connected to the outer side of the slide, a magnetic block one is installed on one side of the fixing block, a magnetic block two is installed on the top of the ear plate, and the magnetic block two is magnetically connected to the magnetic block one at the corresponding position.

[0017] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0018] This application uses a filter screen to filter the falling masterbatch raw material, preventing impurities from entering the processing equipment. This helps improve the product quality of the masterbatch, reduces wear and potential damage to the processing equipment caused by these impurities, and the filter screen rotates back and forth in a certain direction during filtration, which has a screening effect on impurities and improves the separation efficiency. At the same time, it also avoids the raw material clogging the filter screen. In addition, the filter screen can be selectively tilted to the left or right, so that the appropriate discharge hole can be selected to discharge the separated impurities into the inner cavity of the pipeline according to the situation. The rotatability gives the system greater flexibility and adaptability.

[0019] During the screening process, both discharge holes are closed. When the screening is finished and the impurities need to be discharged, the filter screen is rotated to an inclined position, and the baffle on one side is slid upward to open the discharge hole on that side for discharge. During operation, the two baffles can close the discharge holes to ensure the normal screening operation of the filter screen. Sliding the baffles upward will open the discharge holes, which facilitates the discharge of impurities and makes the operation convenient. Attached Figure Description

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 and Figure 2 This application discloses an automatic feeding device for color masterbatch production, comprising a feeding hopper 1, the bottom of which is connected to a pipe 2, and discharge holes 3 on both sides of the pipe 2; a filter element 4, which is disposed through the inner cavity of the pipe 2, and includes a rotatable filter screen 42 located in the inner cavity of the pipe 2, and a fixing frame 43 that is synchronously linked with the filter screen 42 is also provided on the outer side of the feeding hopper 1; a driving element 5 and a blocking element 6, which are disposed on the outer side of the pipe 2, and the driving element 5 includes a rotatable connecting rod 53 and a protrusion 54, one end of which is movably connected to the fixing frame 43.

[0028] Reference Figure 3 and Figure 4 The filter element 4 also includes a rotating rod 41 rotatably connected to the inner cavity of the pipe 2. The filter screen 42 is fixedly connected to the rotating rod 41 and the rotating rod 41 is located at the central axis of the filter screen 42. It is used to filter the color masterbatch raw material so that larger particles are separated.

[0029] The rotating rod 41 is located at the central axis of the filter screen 42, which serves to support and drive the filter screen 42 to rotate. When the color masterbatch raw material passes through the pipe 2, it will come into contact with the filter screen 42. Since the aperture of the filter screen 42 is designed to be smaller than the larger particles in the color masterbatch raw material, these larger particles will be intercepted by the filter screen 42, while the smaller particles can pass through the filter screen 42 smoothly.

[0030] Reference Figure 3 The two side walls of pipe 2 are set as arc surfaces, and the curvature of the arc surfaces is adapted to the rotation path of filter screen 42.

[0031] When the filter screen 42 rotates along its predetermined path under the drive of the rotating rod 41, its edge moves smoothly along the arc surface of the side wall of the pipe 2. This design ensures that the filter screen 42 will not generate excessive friction or collision with the side wall of the pipe 2 during rotation, thereby maintaining the smoothness and stability of rotation. At the same time, due to the arc surface design, the filter screen 42 can open or close the discharge hole 3 when it rotates to a specific position, so as to achieve the smooth discharge of impurities.

[0032] Reference Figure 3 and Figure 4 One end of the rotating rod 41 extends movably through the outside of the pipe 2. The fixed frame 43 is fixedly connected to the outer end of the rotating rod 41. The driving component 5 includes a mounting frame 51 fixedly connected to the outside of the pipe 2. A driving part 52 is fixedly installed on the top of the mounting frame 51. The driving part 52 is specifically a stepper motor. One side of the connecting rod 53 is connected to the output shaft of the driving part 52. The protruding post 54 is fixedly connected to one side of the connecting rod 53 and is used to reciprocate the filter screen 42 to achieve screening. It can also be rotated to an inclined state to discharge impurities.

[0033] The interaction between the rotation of the protruding post 54 and the rotating rod 41 and the fixed frame 43 causes the rotating rod 41 to rotate, which in turn drives the filter screen 42 to rotate together. During the feeding process, the filter screen 42 rotates back and forth, thereby screening the impurities and improving the efficiency of impurity separation. The raw materials roll on the surface of the filter screen 42, which helps to prevent the surface of the filter screen 42 from becoming blocked. In addition, when the filter screen 42 rotates to an inclined state, it pushes the baffle plate 61 so that the discharge hole 3 on the lower side of the filter screen 42 is in an open state. Under the action of gravity, the impurities are discharged from the inner cavity of the pipe 2, and the discharge hole 3 at the higher part of the discharge hole 3 is in a closed state.

[0034] Reference Figure 1 and Figure 2 The shielding component 6 includes a shielding plate 61 located outside the two discharge holes 3. The shielding plate 61 is adapted to the arc surface on both sides of the pipe 2. Ear plates 62 are fixedly connected to both sides of the shielding plate 61. Two symmetrically distributed sliding grooves 63 are opened on the other two sides of the pipe 2. The inner cavity of the sliding groove 63 allows the ear plates 62 at the corresponding positions to slide, which is used to shield the discharge holes 3 to prevent raw materials from falling.

[0035] The shape of the baffle plate 61 is adapted to the arc surfaces on both sides of the pipe 2 to ensure a tight fit. On the one hand, it can prevent the raw materials from falling from the side, ensuring the normal screening operation of the filter screen 42. On the other hand, it is also convenient to push the baffle plate 61 on one side to discharge the material on that side.

[0036] Reference Figure 2 and Figure 5 A fixing block 64 is fixedly connected to the outside of the slide 63. A magnetic block 65 is installed on one side of the fixing block 64. A magnetic block 66 is installed on the top of the ear plate 62. The magnetic block 66 is magnetically connected to the magnetic block 65 at the corresponding position.

[0037] When the baffle plate 61 is pushed to the outside of the discharge hole 3, the ear plate 62 slides along the groove 63 until the second magnetic block 66 and the first magnetic block 65 are in close contact and magnetically connected. This helps to ensure the stability of the baffle plate 61 when it blocks the discharge hole 3 and prevents accidental movement caused by vibration or impact.

[0038] In summary, the automatic feeding equipment for masterbatch production disclosed in this application can be used by first placing the collection device below the discharge holes 3 and installing the device at the feed inlet of the processing equipment. Both discharge holes 3 are closed. The drive unit 52 is turned on, and the drive unit 52 drives the connecting rod 53 and the protrusion 54 to rotate. The protrusion 54 pushes the fixed frame 43, the rotating rod 41 and the filter screen 42 to reciprocate around the rotating rod 41. The raw material is put in from the top of the feeding hopper 1 and enters the inner cavity of the pipe 2. After being screened by the filter screen 42, impurities can be quickly separated, and blockage during the filtration process is prevented. After screening, the filter screen 42 is rotated to an inclined position, and the baffle plate 61 on one side is slid upward, so that the discharge hole 3 on that side is opened to discharge impurities. Finally, the impurities are collected by the collection device on that side. The discharge hole 3 on one side can be selected for discharge according to the actual situation, which improves flexibility.
