Description

Technical Field

[0001] This utility model relates to the field of food production technology, and in particular to a powder addition device in the process of producing food contact masterbatch. Background Technology

[0002] Color masterbatch is a color additive used in plastic processing. It is usually made of a mixture of resin and pigment or dye. Color masterbatch can be added during the plastic production process to achieve the desired color effect in plastic products. With the increasing requirements of the food industry for product appearance and packaging, color masterbatch, as an important color additive, is widely used in the production of food contact materials. In the production process of color masterbatch, the addition of powder is a key step, so a powder addition device is needed in the production process of food contact color masterbatch.

[0003] Traditional food contact masterbatches require the addition of powder during production. This powder typically needs to be weighed before addition to ensure precise dosage, a process that is time-consuming and inefficient. Furthermore, the weighed powder is often added to the mixing equipment all at once, which can lead to uneven mixing, sedimentation, or aggregation. This results in significant inconsistencies in the color and properties of the final masterbatch, affecting the product's appearance quality. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a powder addition device for the production of food contact masterbatches.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A powder addition device for producing food contact masterbatch includes an operating table. A connecting cylinder is installed through one end of the top of the operating table. A feed pipe is fixed to the side wall of the connecting cylinder. Two support frames are fixed to the top of the operating table, and the same rectangular sleeve is fixed to the top of the two support frames. A storage hopper is fixed to the top of the rectangular sleeve and is connected to the rectangular sleeve. A connecting hopper is fixed to one end of the bottom of the rectangular sleeve and is connected to the rectangular sleeve. A U-shaped plate is slidably connected inside the rectangular sleeve. The two symmetrical outer side walls of the rectangular sleeve are provided with a moving mechanism for moving the U-shaped plate. The side wall of the U-shaped plate is provided with a sealing mechanism for sealing the storage hopper. A cylinder is fixed to the bottom of the connecting hopper, and both ends of the cylinder are connected to the connecting cylinder and the connecting hopper, respectively. A conveying mechanism for conveying powder is provided inside the cylinder. A second rotary valve is rotatably connected to the top of the connecting cylinder. The connecting cylinder has a rotating mechanism at its top for rotating a second rotating shaft. A circular mesh plate is fitted onto the side wall of the second rotating shaft, and the circular mesh plate is fixed to the connecting cylinder. Two arc-shaped scrapers are symmetrically fixed to the side wall of the connecting cylinder, and both arc-shaped scrapers are located above the circular mesh plate. A stirring mechanism for stirring is provided on the side wall of the second rotating shaft. During use, this device can achieve quantitative addition of powder by setting a U-shaped plate inside the rectangular sleeve and cooperating with two moving mechanisms, eliminating the need to weigh the powder, saving time and improving work efficiency. The powder can be fed into the connecting cylinder by a conveying mechanism in conjunction with the cylinder, and the two arc-shaped scrapers are rotated by the rotating mechanism in conjunction with the second rotating shaft to evenly scrape the powder into the bottom of the connecting cylinder, avoiding adding the powder into the equipment all at once, preventing the powder from settling or agglomerating during the mixing process, and improving the appearance quality of the product.

[0007] As a further embodiment of this utility model, the moving mechanism includes a support plate fixed to the outer wall of one end of a rectangular sleeve. A groove is formed on the outer wall of the rectangular sleeve, and a slider is slidably connected to the inner wall of the groove. The slider and the U-shaped plate are fixed. An electric telescopic rod is fixed to the inner wall of the support plate, and the telescopic end of the electric telescopic rod is fixed to the slider. The sealing mechanism includes a baffle fixed to the top of the outer wall of one end of the U-shaped plate. The baffle is adapted to the storage hopper. Driving two electric telescopic rods in conjunction with two sliders moves the U-shaped plate along the inner wall of the rectangular sleeve until the baffle is directly below the storage hopper, sealing the bottom of the storage hopper. At this time, the U-shaped plate moves to the top of the connecting hopper, and the powder falls into the connecting hopper. This allows for quantitative addition of powder without weighing, saving time and improving work efficiency.

[0008] As a further embodiment of this utility model, the conveying mechanism includes a first rotating shaft, which is rotatably connected to the inner side wall of one end of the cylinder. An auger is sleeved on the side wall of the first rotating shaft. A second motor is fixed to the outer side wall of one end of the cylinder, and the output shaft of the second motor is fixed to the first rotating shaft. The second motor drives the first rotating shaft to rotate, which in turn drives the auger to rotate, conveying the powder into the connecting cylinder. At this time, the powder falls on the top of the circular mesh plate, avoiding adding the powder into the connecting cylinder all at once.

[0009] As a further embodiment of this utility model, the rotating mechanism includes a first motor, which is fixed at the middle of the top of the connecting cylinder. The output shaft of the first motor and the second rotating shaft are fixed together. The stirring mechanism includes multiple stirring rods, which are all fixed on the side wall of the second rotating shaft and located below the circular mesh plate. The first motor drives the second rotating shaft to rotate, and the rotation of the second rotating shaft drives the multiple stirring rods to rotate, thereby mixing the raw materials and powders and improving the appearance quality of the product.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, this device can achieve quantitative addition of powder by setting a spiral plate inside the rectangular sleeve and cooperating with two moving mechanisms, eliminating the need to weigh the powder, saving time and improving work efficiency.

[0012] 2. The powder can be fed into the connecting cylinder by the conveying mechanism and the cylinder. At this time, the powder falls on the top of the circular screen plate and drives the second rotating shaft to rotate with the rotating mechanism. This drives the two arc-shaped scrapers to rotate and scrape the powder evenly into the bottom of the connecting cylinder. This avoids adding the powder into the equipment all at once and prevents the powder from settling or agglomerating during the mixing process, thus improving the appearance quality of the product.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1 - Figure 4A powder addition device for the production of food contact masterbatch includes an operating table 1. A connecting cylinder 4 is installed through one end of the top of the operating table 1. A feed pipe 18 is fixed to the side wall of the connecting cylinder 4. Two support frames 2 are fixed to the top of the operating table 1. The same rectangular sleeve 3 is fixed to the top of the two support frames 2. A storage hopper 10 is fixed to the top of the rectangular sleeve 3, and the storage hopper 10 is connected to the rectangular sleeve 3. A connecting hopper 7 is fixed to one end of the bottom of the rectangular sleeve 3, and the connecting hopper 7 is connected to the rectangular sleeve 3. The connecting hopper 7 serves as a powder receiving part, responsible for guiding the powder falling from the U-shaped plate 8 into the connecting cylinder 4. A rectangular sleeve 3 has a slidingly connected spiral plate 8 inside. The spiral plate 8 moves within the rectangular sleeve 3, allowing for the quantitative addition of powder. The rectangular sleeve 3 has symmetrical outer walls equipped with moving mechanisms for the spiral plate 8. The spiral plate 8 has a sealing mechanism on its side wall for sealing the storage hopper 10. A cylinder 6 is fixed to the bottom of the connecting hopper 7, and both ends of the cylinder 6 are connected to the connecting cylinder 4 and the connecting hopper 7, respectively. The cylinder 6 has a conveying mechanism inside for transporting powder. A second rotating shaft 20 is rotatably connected to the top of the connecting cylinder 4. The top of the connecting cylinder 4 has a rotating mechanism for rotating the second rotating shaft 20. A circular screen plate 19 is fitted onto the side wall of the second rotating shaft 20, and the circular screen plate 19 is fixed to the connecting cylinder 4. The circular screen plate 19 serves to separate and screen, ensuring that the powder falls evenly into the connecting cylinder 4, preventing a large amount of powder from entering at once, and reducing sedimentation or aggregation. Two arc-shaped scrapers 22 are symmetrically fixed to the side wall of the connecting cylinder 4, and both arc-shaped scrapers 22 are located above the circular screen plate 19. The arc-shaped scrapers 22 are responsible for evenly scraping the powder falling on the top of the circular screen plate 19 to the bottom of the circular screen plate 19, ensuring uniform distribution of the powder and preventing unevenness during the mixing process. The device is equipped with a stirring mechanism. During use, the rectangular sleeve 3 has a U-shaped plate 8 inside, which, together with two moving mechanisms, enables the quantitative addition of powder without weighing, saving time and improving work efficiency. The conveying mechanism, together with the cylinder, can feed the powder into the connecting cylinder 4. The rotating mechanism, together with the second rotating shaft, drives the two arc-shaped scrapers 22 to rotate, so that the powder is evenly scraped into the bottom of the connecting cylinder 4. This avoids adding the powder into the equipment all at once, preventing the powder from settling or agglomerating during the mixing process, and improving the appearance quality of the product.

[0020] In this embodiment, the moving mechanism includes a support plate 15, which is fixed to the outer wall of one end of a rectangular sleeve 3. A groove 17 is provided on the outer wall of the rectangular sleeve 3, and a slider 14 is slidably connected to the inner wall of the groove 17. The slider 14 is fixed to the U-shaped plate 8. An electric telescopic rod 16 is fixed to the inner wall of the support plate 15, and the telescopic end of the electric telescopic rod 16 is fixed to the slider 14. The sealing mechanism includes a baffle 9, which is fixed to the top of the outer wall of one end of the U-shaped plate 8. The baffle 9 is adapted to the storage hopper 10 and is used to seal the storage hopper. The bottom of the hopper 10 ensures that powder will not leak or overflow from the storage hopper 10 before it needs to be added. The two electric telescopic rods 16, together with the two sliders 14, drive the U-shaped plate 8 to move along the inner wall of the rectangular sleeve 3 until the baffle 9 is directly below the storage hopper 10, sealing the bottom of the storage hopper 10. At this time, the U-shaped plate 8 moves to the top of the connecting hopper 7, and the powder will fall into the connecting hopper 7. In this way, the powder can be added quantitatively without weighing, saving time and improving work efficiency.

[0021] In this embodiment, the conveying mechanism includes a first rotating shaft 11, which is rotatably connected to the inner side wall of one end of the cylinder 6. An auger 12 is sleeved on the side wall of the first rotating shaft 11. A second motor 13 is fixed to the outer side wall of one end of the cylinder 6, and the output shaft of the second motor 13 is fixed to the first rotating shaft 11. The second motor 13 drives the first rotating shaft 11 to rotate, which in turn drives the auger 12 to rotate, conveying the powder into the connecting cylinder 4. At this time, the powder falls on the top of the circular mesh plate 19, avoiding adding the powder into the connecting cylinder 4 all at once.

[0022] In this embodiment, the rotating mechanism includes a first motor 5, which is fixed at the top center of the connecting cylinder 4. The output shaft of the first motor 5 and the second rotating shaft 20 are fixed together. The stirring mechanism includes multiple stirring rods 21, which are all fixed on the side wall of the second rotating shaft 20 and located below the circular mesh plate 19. The first motor 5 drives the second rotating shaft 20 to rotate, and the rotation of the second rotating shaft 20 drives the multiple stirring rods 21 to rotate, thus mixing the raw materials and powders and improving the appearance quality of the product.

[0023] The working principle of this embodiment is as follows: During use, the raw materials are fed into the connecting cylinder 4 through the feed pipe 18, and the powder to be added is placed into the storage hopper 10. At this time, some of the powder falls into the U-shaped plate 8. When adding, the power switches of the two electric telescopic rods 16 are turned on, driving the two electric telescopic rods 16 to move the U-shaped plate 8 along the inner wall of the rectangular sleeve 3 in conjunction with the two sliders 14 until the baffle 9 is directly below the storage hopper 10, sealing the bottom of the storage hopper 10. At this time, the U-shaped plate 8 moves to the top of the connecting hopper 7, and the powder will fall into the connecting hopper 7. This achieves quantitative addition of powder without the need to weigh the powder, saving time and improving work efficiency. At this time, the second motor 1 is turned on. The power switch of motor 3 drives the second motor 13 to rotate the first rotating shaft 11, which in turn drives the auger 12 to rotate, conveying the powder into the connecting cylinder 4. At this time, the powder falls on the top of the circular mesh plate 19. Simultaneously, the power switch of the first motor 5 is turned on, driving the first motor 5 to rotate the second rotating shaft 20. The rotation of the second rotating shaft 20 drives the two arc-shaped scrapers 22 to rotate, evenly scraping the powder that has fallen on the top of the circular mesh plate 19 to the bottom of the circular mesh plate 19, avoiding adding the powder into the connecting cylinder 4 at once, and preventing the powder from settling or agglomerating during the mixing process. At this time, the rotation of the second rotating shaft 20 drives the multiple stirring rods 21 to rotate, mixing the raw materials and powder, improving the appearance quality of the product.
