Description

Technical Field

[0001] This utility model relates to the field of masterbatch conveying technology, specifically a masterbatch conveying device. Background Technology

[0002] Color masterbatch is a widely used colorant in the plastics processing industry. It is made by uniformly mixing pigments or dyes with carrier resins and other additives to form granules, which facilitate coloring during plastic processing. Color masterbatch conveying devices are key equipment used to transport color masterbatch from storage or processing equipment to the plastic processing equipment requiring coloring. Among these, screw conveyors are widely used in the conveying process of color masterbatch due to their simple structure and high conveying efficiency.

[0003] However, traditional screw conveyor systems have some significant drawbacks when conveying masterbatches. Friction between the screw conveyor blades and the masterbatches during transport causes the masterbatches' temperature to rise. Prolonged exposure to high temperatures can adversely affect the properties of the masterbatches, such as reducing their coloring effect or altering their physical properties. Especially during continuous transport, the heat generated by friction gradually accumulates, causing the internal temperature of the screw conveyor to rise continuously, further exacerbating the degradation of the masterbatches' properties. Therefore, designing a conveyor system that can effectively reduce the heat generated during transport and protect the properties of the masterbatches has become an urgent problem to be solved.

[0004] Therefore, we propose a masterbatch conveying device. Utility Model Content

[0005] The purpose of this invention is to provide a masterbatch conveying device to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a masterbatch conveying device, comprising:

[0007] Two screw conveyors are arranged side by side on a support frame, and both screw conveyors are driven simultaneously by a drive mechanism. Each screw conveyor is provided with a feed inlet.

[0008] The tilting pipe is installed on the intermittent lifting mechanism, which is connected to the drive mechanism through a transmission component. When the drive mechanism is in operation, the intermittent lifting mechanism drives the tilting pipe to rise and fall periodically through the transmission component, thereby alternately tilting the masterbatch into the two feed ports.

[0009] As a further description of the above technical solution: the intermittent lifting mechanism includes a conveyor belt mounted on a support, and a section of the conveyor belt surface is provided with meshing teeth. When the conveyor belt is rotated by the transmission member, the meshing teeth periodically mesh with the gears that are rotatably mounted on the screw conveyor housing.

[0010] As a further description of the above technical solution: the intermittent lifting mechanism also includes a geared rack that is vertically slidably disposed on the screw conveyor housing, and a slot on the screw conveyor housing that is laterally slidably disposed and on which a slider is slidably installed. A crank is rotatably disposed at an eccentric position on the gear, and the end of the crank away from the gear is rotatably disposed on the slider. A push plate that is inserted into the slot of the geared rack is also disposed on the slider. The tilting tube is disposed on the geared rack.

[0011] As a further description of the above technical solution: Two wedge-shaped blocks are respectively provided at the two ends of the toothed rack corresponding to the outer wall and inner wall surface of the slot. When the toothed rack moves upward to the maximum stroke, the wedge block located at the lower end of the toothed rack abuts against the slot, causing the push plate to separate from the toothed rack slot.

[0012] As a further description of the above technical solution: during the process from the meshing teeth engaging with the gear to the meshing teeth separating from the gear, the rotation angle of the gear is an integer multiple of 360 degrees.

[0013] As a further description of the above technical solution: the transmission component is a worm wheel and a worm gear that mesh with each other, wherein the worm wheel is rotatably mounted on the bracket and connected to the shaft of the conveyor belt, and the worm gear is connected to the drive mechanism.

[0014] As a further description of the above technical solution: a fixing plate with one end inserted into the slot of the toothed rack is also fixedly provided on the card slot. When the push plate moves downward in the up-and-down reciprocating motion cycle, the fixing plate is used to prevent the toothed rack from falling back.

[0015] As a further description of the above technical solution: the width of the feed inlet is greater than the width of the tilting pipe, and the feed end of the tilting pipe is connected to an external conveying device.

[0016] In the above technical solution, the color masterbatch conveying device provided by this utility model has the following beneficial effects:

[0017] Alternating feeding prevents heat accumulation: By alternating feeding with two screw conveyors, heat accumulation caused by prolonged use of a single screw conveyor can be avoided, thus preventing the color masterbatch from changing its properties due to excessive heat generated by friction.

[0018] Continuous conveying without the need for downtime for heat dissipation: Because two screw conveyors work alternately, the device can continuously convey masterbatch without stopping the machine, without interrupting the conveying process due to heat dissipation, thereby improving production efficiency.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-3 This utility model provides a technical solution: a color masterbatch conveying device, including two screw conveyors 1 arranged side by side on a support 7, and the two screw conveyors 1 are driven simultaneously by a driving mechanism. Each of the two screw conveyors 1 is provided with a feed inlet 2, and the other end of the two screw conveyors 1 is provided with a discharge outlet 8.

[0027] In one embodiment of the present invention, the driving mechanism includes a drive motor 3 mounted on the housing of the screw conveyor 1 via a frame. A synchronous belt is provided between the power input ends of the two screw conveyors 1 via synchronous pulleys. The power output end of the drive motor 3 is connected to one of the synchronous pulleys. Thus, after the drive motor 3 is started, the screw conveyor plates in the two screw conveyors 1 can be started simultaneously. After the masterbatch enters the screw conveyor 1 through the feed port 2, it can be conveyed by the rotating screw conveyor plates until the masterbatch is discharged through the discharge port 8.

[0028] To address the issue of excessive heat generated by friction between the screw conveyor blades and the masterbatch during prolonged conveying of the masterbatch via the screw conveyor 1, which could alter the properties of the masterbatch, the masterbatch conveying device also includes a tilting pipe 11 mounted on an intermittent lifting mechanism. This intermittent lifting mechanism is connected to a drive mechanism via a transmission component. When the drive mechanism is operational, the transmission component causes the intermittent lifting mechanism to periodically raise and lower the tilting pipe 11, alternately tilting the masterbatch into the two feed inlets 2. Thus, when the drive mechanism is activated, the tilting pipe 11 moves upward via a transmission component. The width of the feed inlet 2 is greater than the width of the tilting pipe 11, and the feed end of the tilting pipe 11 is connected to external conveying equipment. As the tilting pipe 11 moves upward... The masterbatch from the external conveying device is fed into the screw conveyor 1 through the feed inlet 2. When the height of the tilting pipe 11 is low, it conveys the masterbatch into the screw conveyor located below. As the height increases, the conveying direction changes, and the masterbatch is conveyed into the feed inlet 2 of the screw conveyor 1 located above. After conveying the masterbatch through one screw conveyor 1 for a period of time, the screw conveyor 1 can be stopped to feed, and the other screw conveyor 1 can start feeding. By setting the two screw conveyors 1 to feed alternately, it is possible to prevent one screw conveyor 1 from being used for too long and generating too much heat that could damage the masterbatch. The conveying effect is better, and the conveying process of the masterbatch can be carried out continuously without stopping the screw conveyor 1 to dissipate heat, thus improving the conveying efficiency of the masterbatch.

[0029] In another embodiment of the present invention, the intermittent lifting mechanism includes a conveyor belt 6 mounted on a support 7, and a section of the belt surface of the conveyor belt 6 is provided with meshing teeth 17. When the conveyor belt 6 is rotated by the transmission member, the meshing teeth 17 periodically mesh with the gear 16 rotatably mounted on the housing of the screw conveyor 1. The transmission member is a worm wheel 5 and a worm 4 meshing with each other. The worm wheel 5 is rotatably mounted on the support 7 and connected to the shaft of the conveyor belt 6. The worm 4 is connected to another synchronous pulley that is far away from the drive motor 3. In this way, when the drive motor 3 is in the starting state, the conveyor belt 6 can be rotated by the mutual cooperation between the worm wheel 5 and the worm 4. During one rotation cycle of the conveyor belt 6, the meshing teeth 17 on it will mesh with the gear 16 once. That is, when the conveyor belt 6 rotates one full revolution, the gear 16 rotates once.

[0030] When gear 16 rotates, the intermittent lifting mechanism also includes a rack 9 vertically slidably mounted on the housing of the screw conveyor 1, and a slot 13 horizontally slidably mounted on the housing of the screw conveyor 1 and on which a slider 14 is slidably installed. A crank 15 is rotatably mounted at an eccentric position on gear 16, and the end of crank 15 away from gear 16 is rotatably mounted on slider 14. A push plate 12, inserted into the slot of rack 9, is also mounted on slider 14 via a torsion spring. The tilting tube 11 is mounted on rack 9. When gear 16 rotates, crank 15 rotates synchronously, causing slider 14 to reciprocate up and down within slot 13, thus causing push plate 12 to... The push plate 12 is designed to rotate clockwise but not counterclockwise. When the push plate 12 moves downward, it will rub against the inclined surface of the slot of the toothed rack 9. The push plate 12 rotates clockwise. After the push plate 12 passes the inclined surface, it returns to its original position under the action of the torsion spring. At this time, the slider 14 begins to move upward under the action of the crank 15. The push plate 12 pushes the slot end of the toothed rack 9 to move upward, thereby moving the entire toothed rack 9 and the tilting tube 11 on the toothed rack 9 upward. This continuously increases the height of the tilting tube 11, thereby realizing the periodic delivery of the masterbatch to different screw conveyors 1 through the tilting tube 11.

[0031] When the toothed rack 9 and the tilting tube 11 move upward to their maximum stroke, two wedge blocks 10 are respectively set at the two ends of the toothed rack 9 corresponding to the outer and inner wall surfaces of the slot 13. When the toothed rack 9 moves upward to its maximum stroke, the wedge block 10 at the lower end of the toothed rack 9 abuts against the slot 13, causing the slot 13 to move laterally, thereby separating the push plate 12 from the slot of the toothed rack 9. At this time, the toothed rack 9 falls under the action of gravity until the wedge block 10 at the top abuts against the slot 13, causing the slot 13 to return to its original position. By repeating this process, the toothed rack 9 can move up and down continuously, thereby conveying the masterbatch in different forms through the tilting tube 11.

[0032] It should be noted that during the process from the engagement of the meshing tooth 17 and the gear 16 to the separation of the meshing tooth 17 and the gear 16, the rotation angle of the gear 16 is an integer multiple of 360 degrees, that is, the number of rotations of the gear 16 is an integer number of rotations. The push plate 12 can perform a complete up and down movement, thereby pushing the rack 9 to move upward.

[0033] Furthermore, a fixing plate 18 is fixedly installed on the slot 13, with one end inserted into the slot of the rack 9. When the push plate 12 moves downward during the up-and-down reciprocating motion cycle, the fixing plate 18 is used to prevent the slot on the rack 9 from falling back due to lack of support.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
