Description

A modified masterbatch production system Technical Field

[0001] This application relates to the field of plastic production equipment technology, and more specifically, to a modified masterbatch production system. Background Technology

[0002] Color masterbatch coloring is the most common method for coloring plastics today. Colorants dispersed on a carrier are simply mixed with the masterbatch resin and then used to manufacture plastics. The plastic molding process generally involves stirring, extrusion, cooling, drying, cutting, and screening before final molding. A granulator is a molding machine that can shape materials into specific forms. A granulator consists of a stirring mechanism, a cooling channel, and a cutting mechanism. However, existing granulator cooling channels cannot recirculate cooling water.

[0003] Chinese Patent No. CN110640931A discloses a plastic granulator, which includes a cooling device, a pelletizing device connected to the extrusion end of the cooling device, and a water tank for circulating and supplying room temperature cold water to the cooling device. The room temperature cold water output end of the water tank is directly connected to the input end of the cooling device, and a heat dissipation device is provided between the room temperature cold water input end of the water tank and the output end of the cooling device. The cooling device is used to receive the molten strip plastic extruded by the plastic granulator and cool it. The pelletizing device is used to receive the strip rigid plastic extruded by the cooling device and pelletize it. Its advantage is that by drawing room temperature cold water from the water tank and directly contacting it with the molten strip plastic, the room temperature cold water and the molten strip plastic exchange heat to become high temperature hot water. The high temperature hot water is then physically cooled and converted back into room temperature cold water and drawn back into the water tank, so that the room temperature cold water can be recycled.

[0004] Existing technologies have achieved the recycling of cooling water, but their plastic inlets are still set to a fixed size. Plastic raw materials are usually of different hardness, size and shape. A single-sized inlet is very easy to get clogged, and the staff cannot identify the blockage in time. Severe blockage can easily lead to damage to the inside of the equipment. In view of this, we propose a modified color masterbatch production system. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a modified color masterbatch production system to solve the problems mentioned in the background art.

[0007] 2. Technical Solution

[0008] A modified masterbatch production system includes a granulator body and a feeding mechanism.

[0009] The granulator body has a feeding mechanism at its top and a receiving chamber on its outer side.

[0010] A servo motor is fixedly connected to the inner side of the receiving chamber, and an anti-blocking component is fixedly connected to the output end of the servo motor. The anti-blocking component is located inside the feeding mechanism. When the inner side of the feeding mechanism is blocked, the anti-blocking component receives information to control the servo motor to start. The servo motor starts to change the position of the anti-blocking component inside the feeding mechanism, thereby clearing the plastic raw material inside the feeding mechanism.

[0011] As an optional solution to the technical solution of this application, the anti-blocking component includes a connecting rod, the output end of the servo motor is fixedly connected to the connecting rod, the other end of the connecting rod is fixedly connected to an internal spline shaft, the outer side of the internal spline shaft is meshed with a connecting structure, the outer side of the connecting structure is symmetrically meshed with a third bevel gear, the bottom end of the third bevel gear is fixedly connected to a fixing plate, and the other end of the fixing plate is fixedly connected to an arc-shaped ring.

[0012] As an optional solution to the technical solution of this application, the arc-shaped ring is initially embedded in the inner side of the limiting groove, and the limiting groove is located at the bottom of the feeding mechanism.

[0013] As an optional solution to the technical solution of this application, an arc-shaped groove is provided on the inner side of the arc-shaped ring, a limit ring is slidably connected to the inner side of the arc-shaped groove, and a pressure sensor is provided at the connection between the limit ring and the arc-shaped ring.

[0014] As an optional solution to the technical solution in this application, the pressure sensor receives the pressure transmitted by the arc ring. When the pressure exceeds the threshold, the pressure sensor transmits information to the control center, thereby triggering the start of the servo motor electrically connected to it.

[0015] As an optional solution to the technical solution of this application, the bottom end of the third bevel gear is fixedly connected to a fixed shaft, the bottom end of the fixed shaft is rotatably connected to the bottom end of the receiving chamber, and a fixed plate is fixedly connected to the outside of the fixed shaft.

[0016] As an optional solution to the technical solution of this application, the connection structure consists of an external spline shaft, a first bevel gear and a second bevel gear. The external spline shaft is splinedly connected to the internal spline shaft, and the first bevel gear and the second bevel gear are fixedly connected to both ends of the external spline shaft, respectively.

[0017] The gear ratio between the first bevel gear and the second bevel gear is 2:3.

[0018] As an optional solution to the technical solution of this application, the bottom end of the external spline shaft passes through the fixing block, the fixing block is fixedly installed inside the receiving chamber, and the connecting structure can slide inside the fixing block.

[0019] As an optional solution to the technical solution of this application, the feeding mechanism and the limiting ring are of equal size in the normal feeding state.

[0020] 3. Beneficial effects

[0021] Compared to existing technologies, the advantages of this application are:

[0022] This application, through the setting of the anti-clogging component, ensures that when plastic material becomes clogged inside the feeding mechanism, the limiting ring receives pressure and slides inside the arc-shaped ring. The limiting ring squeezes the pressure sensor, and the pressure sensor receives a signal feedback to control the servo motor to start. The servo motor drives the connecting rod to rotate, which in turn drives the inner spline shaft to move and rotate simultaneously. The movement and rotation of the inner spline shaft, in turn, drives the entire linkage structure to move and rotate simultaneously. The rotation of the entire linkage structure drives the two third bevel gears meshing with it to rotate in opposite directions. The two third bevel gears move inside the feeding mechanism, squeezing one side of the clogged plastic material while leaving the other side unrestricted. The material space structure within the feeding mechanism is improved to promptly clear blockages and enhance the device's practicality. Through the connection structure, the force of the servo motor driving the connecting rod and inner spline shaft is converted into a force that simultaneously drives the outer spline shaft in the linkage structure. The outer spline shaft slides inside the fixed block, causing the first and second bevel gears to mesh with the third bevel gear sequentially. Due to the different gear ratios of the first and second bevel gears, the rotational speeds of the third bevel gear are different, resulting in varying degrees of rotation of the arc-shaped ring. This achieves the goal of applying multiple forces to the blockage of plastic material within the feeding structure, improving clearing efficiency. Attached Figure Description

[0029] Please refer to Figures 1-3. This application provides a technical solution:

[0030] Referring to Figures 1, 2 and 3, and referring to the prior art, the granulator consists of a stirring mechanism, a cooling channel and a cutting mechanism. The stirring mechanism, cooling channel and cutting mechanism are all controlled by the control center. The granulator body 1 has a feeding mechanism 2 at the top and a limiting groove 21 at the bottom. An anti-blocking component 5 is provided inside the limiting groove 21. The anti-blocking component 5 can move to a certain position in the limiting groove 21. A receiving chamber 3 is provided outside the feeding mechanism 2.

[0031] Workers feed plastic raw materials of different shapes and sizes into the feeding mechanism 2. The raw materials fall into the granulator body 1 through the feeding mechanism 2 for subsequent shaping and granulation operations.

[0032] A servo motor 4 is fixedly connected to the inside of the receiving chamber 3. An anti-blocking component 5 is fixedly connected to the output end of the servo motor 4. The anti-blocking component 5 includes an arc ring 56, a pressure sensor 57, and a limiting ring 58. In the normal feeding state, the feeding mechanism 2 and the limiting ring 58 are the same size. The plastic raw material is not restricted by the limiting ring 58 and can slide smoothly from the limiting ring 58. In the initial state, the arc ring 56 is embedded in the limiting groove 21. An arc groove is provided on the inside of the arc ring 56. The limiting ring 58 is slidably connected to the inside of the arc groove. A pressure sensor 57 is provided at the connection between the limiting ring 58 and the arc ring 56. The pressure sensor 57 is electrically connected to the servo motor 4. The pressure sensor 57 receives the pressure transmitted by the arc ring 56. After the pressure exceeds the threshold, the pressure sensor 57 transmits information to the control center, thereby triggering the servo motor 4, which is electrically connected to it, to start.

[0033] When a blockage occurs inside the feeding mechanism 2, the blocked material exerts a force on the limiting ring 58. The limiting ring 58 slides into the arc groove inside the arc ring 56 until the limiting ring 58 squeezes the pressure sensor 57. The pressure sensor 57 receives the information and feeds it back to the device control center. The device control center controls the servo motor 4 to start, thereby realizing the timely detection of blockages inside the device so as to make real-time adjustments and clearing, avoiding damage to the device inside due to long-term blockages. At the same time, it also eliminates the need for staff to climb up from time to time to clear the inside of the feeding mechanism 2.

[0034] The anti-blocking component 5 is located inside the feeding mechanism 2. The anti-blocking component 5 includes a connecting rod 51. The output end of the servo motor 4 is fixedly connected to the connecting rod 51. The other end of the connecting rod 51 is fixedly connected to an internal spline shaft 52. The outer side of the internal spline shaft 52 is meshed with a connecting structure 53. The outer side of the connecting structure 53 is symmetrically meshed with a third bevel gear 54. The bottom end of the third bevel gear 54 is fixedly connected to a fixed shaft. The bottom end of the fixed shaft is rotatably connected to the bottom end of the receiving chamber 3. The outer side of the fixed shaft is fixedly connected to a fixed plate 55. The other end of the fixed plate 55 is fixedly connected to an arc-shaped ring 56.

[0035] The servo motor 4 starts and drives the connecting rod 51 in the anti-blocking component 5 to rotate. The rotation of the connecting rod 51 drives the inner spline shaft 52 to rotate. The inner spline shaft 52 drives the connecting structure 53 to rotate. The rotation of the connecting structure 53 drives the connecting structure 53 to rotate smoothly inside the receiving chamber 3 under the restriction of the fixed block. The connecting structure 53 drives the third bevel gears 54 on both sides to rotate in opposite directions. The rotation of the third bevel gears 54 drives the fixed shaft to rotate at the bottom of the receiving chamber 3. The fixed shaft drives the fixed plate 55 to rotate. The fixed plate 55 drives the arc ring 56 to rotate. The two arc rings 56 rotate in opposite directions inside the limiting groove 21. One arc ring 56 no longer restricts the blocked plastic, while the other side applies force to the blocked plastic, thereby changing the spatial structure of the plastic in the blocked state and completing the unblocking operation.

[0036] The connecting structure 53 consists of an external spline shaft 531, a first bevel gear 532, and a second bevel gear 533. The external spline shaft 531 is splinedly connected to the internal spline shaft 52. The first bevel gear 532 and the second bevel gear 533 are fixedly connected to both ends of the external spline shaft 531, respectively. The gear ratio between the first bevel gear 532 and the second bevel gear 533 is 2:3. The bottom end of the external spline shaft 531 passes through a fixed block. The fixed block is fixedly installed inside the receiving chamber 3, and the connecting structure 53 can slide inside the fixed block.

[0037] While the inner spline shaft 52 rotates, it drives the outer spline shaft 531 to rotate. At the same time, the outer spline shaft 531 moves outside the inner spline shaft 52. While the outer spline shaft 531 rotates, it drives the first bevel gear 532 and the second bevel gear 533 fixed on the outside to rotate. The movement of the outer spline shaft 531 drives the first bevel gear 532 and the second bevel gear 533 to mesh with the third bevel gear 54 in turn. When the first bevel gear 532 and the second bevel gear 533 mesh with the third bevel gear 54 respectively, they can drive the third bevel gear 54 to rotate. Since the gear ratio of the first bevel gear 532 and the second bevel gear 533 is 2:3, their speeds are also different. The different speeds drive the arc ring 56 to rotate at different angles in the same amount of time, thereby applying different degrees of force to both sides of the feeding structure 2, which improves the unblocking effect.

[0038] When the plastic material input into the inner side of the feeding mechanism 2 becomes clogged, the clogged plastic material exerts a force on the limiting ring 58. The limiting ring 58 slides inside the arc-shaped ring 56, squeezing the pressure sensor 57. The pressure sensor 57 receives a signal and controls the servo motor 4 to start. The servo motor 4 drives the connecting rod 51 to rotate. The connecting rod 51 drives the connecting structure 53 to rotate through the inner spline shaft 52. The connecting structure 53 drives the third bevel gears 54 on both sides to rotate in opposite directions. The third bevel gears 54 drive the arc-shaped ring 56 to rotate through the fixing plate 55. The two arc-shaped rings 56 displace in opposite directions, applying different forces to the clogged plastic material.

[0039] Servo motor 4 drives connecting rod 51 and inner spline shaft 52 to rotate. Inner spline shaft 52 drives outer spline shaft 531 in linkage structure 53 to move and rotate at the same time. Outer spline shaft 531 slides inside fixed block, so that first bevel gear 532 and second bevel gear 533 mesh with third bevel gear 54 in turn. Since the gear ratio of first bevel gear 532 and second bevel gear 533 is different, the rotation speed of third bevel gear 54 driven by them is different. As a result, arc ring 56 rotates to different degrees, thereby achieving the purpose of applying force to the plastic material blocked inside the feeding structure 2 multiple times. The multiple force changes the spatial structure of the plastic in the blocked state and completes the unblocking operation.
