Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a quantitative dispensing and packaging machine for vitamin E premix. Background Technology

[0002] In the production of vitamin E premixes in feed, pharmaceutical and other fields, manual packaging suffers from low efficiency and poor metering accuracy. The industry has an urgent need for automated quantitative packaging, but existing equipment often suffers from insufficient adaptability to material characteristics or unstable accuracy, which drives the research and development and application of dedicated quantitative packaging machines.

[0003] In existing technologies, when quantitatively dispensing and packaging vitamin E premix, a quantitative weighing and packaging machine is typically used. The premix is ​​transported to the quantitative weighing and packaging machine through a pipeline conveyor structure at the top of the workshop, weighed, and then discharged through the discharge port at the bottom of the quantitative weighing and packaging machine into a tank conveyed by a conveyor belt or a packaging bag held by a person to complete the quantitative packaging. However, the above process has the following two problems: First, the long and complex pipeline transmission path disrupts the premixed state of the premix, resulting in low unit homogeneity and inconsistent quality after quantitative packaging; Second, the traditional feeding method that relies solely on valve control is prone to sudden speed changes, causing quantitative weighing and packaging machines to misjudge and prematurely feed the premix.

[0004] Therefore, a quantitative dispensing and packaging machine for vitamin E premix is ​​proposed. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative dispensing and packaging machine for vitamin E premix, which can solve the problems of low uniformity and quantitative accuracy of existing premixes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative dispensing and packaging machine for vitamin E premix, comprising a quantitative weighing packaging machine, wherein an upper transmission pipe is provided at the top of the quantitative weighing packaging machine, a pretreatment mechanism is movably connected to the bottom of the upper transmission pipe, a lower transmission pipe is movably connected to the bottom of the pretreatment mechanism, a flow rate regulating mechanism is movably connected to the bottom of the lower transmission pipe, the pretreatment mechanism includes a premixing tank, the premixing tank is fixedly connected to the bottom of the upper transmission pipe, the premixing tank is fixedly connected to the top of the lower transmission pipe, a support frame is fixedly connected to the inner side of the premixing tank, a servo motor is fixedly connected to the bottom of the support frame, a support shaft is fixedly connected to the output end of the servo motor, and a swing mixing component is movably connected to the outer side of the support shaft.

[0007] Preferably, the flow rate adjustment mechanism includes a support box, which is fixedly connected to the bottom of the lower transmission pipe. Both sides of the inner side of the support box are slidably connected to a baffle plate, and the bottom of the baffle plate is fixedly connected to a linkage column.

[0008] Preferably, a linkage gear ring is movably connected to the outer side of the linkage column, and the linkage gear ring is rotatably connected to the bottom of the support box.

[0009] Preferably, a stepper motor is fixedly connected to the outside of the lower transmission tube, and a drive gear is fixedly connected to the output end of the stepper motor.

[0010] Preferably, the oscillating mixing assembly includes a support block, which is fixedly connected to the outside of the support shaft. Rotating blocks are rotatably connected to both sides of the support block, and spiral stirring rollers are rotatably connected to opposite sides of the two rotating blocks.

[0011] Preferably, an electronic telescopic rod is rotatably connected to the bottom of the rotating block, and the electronic telescopic rod is rotatably connected to the bottom outside the supporting rotating shaft.

[0012] Preferably, an arc panel is fixedly connected to the top of the support frame.

[0013] Preferably, induction valves are fixedly connected to the top and bottom of the inner side of the premixing tank.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting up a pre-treatment mechanism, divides the pipeline transmission system into an upper transmission pipe and a lower transmission pipe, and adds a premixing tank with a sensing valve in the middle. The premixed material is first piled up in the premixing tank, and then the support shaft is rotated by a servo motor, which drives the spiral stirring rollers on both sides to rotate and turn the material. At the same time, the rotating block is pulled back and forth by an electronic telescopic rod, so that the spiral stirring rollers perform complex back-and-forth oscillation and stirring, so as to achieve a thorough remixing of the material before it enters the lower transmission pipe. This effectively solves the problem of the premixing state being destroyed by long-distance complex pipeline transmission, improves the unit homogeneity, and avoids the situation of inconsistent quality after quantitative packaging.

[0016] 2. This application, by setting a flow rate adjustment mechanism, allows the material to accumulate in a small amount after being shielded at the discharge port by setting a bottom support box and double baffles. Then, the material is driven by a stepper motor to drive the drive gear, which in turn drives the outer meshing linkage gear ring to rotate. The arc-shaped guide groove on the inner side of the linkage gear ring drives the double baffles to slide slowly to both sides through the linkage column, thereby gradually reducing the shielding area and controlling the flow rate. This structure can achieve a uniform and slow entry of premixed material into the quantitative weighing and packaging machine, and can adjust the feeding speed. It effectively avoids the problem of sudden changes in feeding speed that is easy to occur when the traditional method relies solely on valve control, thereby preventing quantitative errors caused by premature feeding due to misjudgment in the quantitative weighing and packaging machine.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The present invention provides the following technical solution:

[0024] A quantitative dispensing and packaging machine for vitamin E premix includes a quantitative weighing and packaging machine 1. The top of the quantitative weighing and packaging machine 1 is provided with an upper transmission pipe 2. The bottom of the upper transmission pipe 2 is movably connected to a pretreatment mechanism 3. The bottom of the pretreatment mechanism 3 is movably connected to a lower transmission pipe 4. The bottom of the lower transmission pipe 4 is movably connected to a flow rate regulating mechanism 5. The pretreatment mechanism 3 includes a premixing tank 31. The premixing tank 31 is fixedly connected to the bottom of the upper transmission pipe 2 and fixedly connected to the top of the lower transmission pipe 4. A support frame 32 is fixedly connected to the inner side of the premixing tank 31. A servo motor 33 is fixedly connected to the bottom of the support frame 32. A support shaft 34 is fixedly connected to the output end of the servo motor 33. A swing mixing component 35 is movably connected to the outer side of the support shaft 34.

[0025] In this embodiment: the pipeline transmission system is divided into an upper transmission pipe 2 and a lower transmission pipe 4 for feeding. A premixing tank 31 is provided between the two. The top and bottom of the premixing tank 31 are equipped with sensing valves 7 to adjust the sealing state of the upper and lower pipeline systems. When the upper transmission pipe 2 is feeding material, the material first enters the premixing tank 31. After a certain amount of material is accumulated, the servo motor 33 inside the premixing tank 31 is started, which drives the output end to rotate the support shaft 34 connected to the center of the support frame 32. When the support shaft 34 rotates, the spiral stirring roller 3503 mounted on the support structure composed of support blocks 3501 and rotating blocks 3502 on both sides will rotate due to the stirring contact force in the transmission, turning the material to achieve premixing. In order to further enhance the mixing efficiency, the swing mixing component 35 can be used to achieve remixing before the material enters the lower transmission pipe 4 for direct feeding, so as to avoid uneven quality.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, the flow rate adjustment mechanism 5 includes a support box 51, which is fixedly connected to the bottom of the lower transmission pipe 4. Both sides of the inner side of the support box 51 are slidably connected to a baffle plate 52, and the bottom of the baffle plate 52 is fixedly connected to a linkage column 53.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a linkage gear ring 54 is movably connected to the outer side of the linkage column 53, and the linkage gear ring 54 is rotatably connected to the bottom of the support box 51.

[0028] Specifically, such as Figure 1 , Figure 2 , Figure 4 As shown, a stepper motor 55 is fixedly connected to the outside of the lower transmission tube 4, and a drive gear 56 is fixedly connected to the output end of the stepper motor 55.

[0029] In this embodiment: after the material is mixed again and enters the feeding conveyor pipe and reaches the discharge port, it is not discharged directly. Instead, it is blocked and a small amount accumulates inside the double baffle plate 52 inside the bottom support box 51. The flow rate is controlled by slowly reducing the blocking area. Specifically, the stepper motor 55 is started, which makes the drive gear 56 at its output end rotate. The drive gear 56 drives the linkage gear ring 54 that is meshed with the outer side. The outer teeth of the linkage gear ring 54 mesh with the drive gear 56. An arc-shaped guide groove is opened inside the linkage groove. A linkage column 53 is provided inside the guide groove. The linkage column 53 is fixedly connected to the baffle plate 52. Therefore, the linkage gear ring 54 can drive the double baffle plate 52 to slide slowly to both sides to reduce the blocking area, so that the premixed material enters the quantitative weighing and packaging machine 1 at a uniform and slow speed. The feeding speed can be adjusted by adjusting the speed and size, avoiding the problem of unstable feeding speed relying solely on the valve.

[0030] Specifically, such as Figure 3 As shown, the oscillating mixing assembly 35 includes a support block 3501, which is fixedly connected to the outside of the support shaft 34. Rotating blocks 3502 are rotatably connected to both sides of the support block 3501, and spiral stirring rollers 3503 are rotatably connected to opposite sides of the two rotating blocks 3502.

[0031] Specifically, such as Figure 3 As shown, an electronic telescopic rod 3504 is rotatably connected to the bottom of the rotating block 3502, and the electronic telescopic rod 3504 is rotatably connected to the bottom of the outer side of the supporting rotating shaft 34.

[0032] In this embodiment: by starting the servo motor 33 inside the premix tank 31, the output end of the servo motor 33 is driven to rotate the support shaft 34 connected to the center of the support frame 32. When the support shaft 34 rotates, the spiral stirring roller 3503 mounted on the support structure composed of the support block 3501 and the rotating block 3502 on both sides will rotate due to the stirring contact force in the transmission, turning the internal material to achieve premixing. To further enhance the mixing efficiency, an electronic telescopic rod 3504 is provided between the rotating block 3502 and the support shaft 34. The two ends of the electronic telescopic rod 3504 are respectively rotatably connected to the bottom of the rotating block 3502 and the outside of the support shaft 34. When it reciprocates, it will pull the rotating block 3502 to reciprocate along the outer wall of the support block 3501, driving the spiral stirring roller 3503 to perform more complex reciprocating oscillation and stirring. During this process, the spiral stirring roller 3503 will still turn the material by rotating, so as to achieve remixing before the material enters the lower section transmission pipe 4 for direct feeding, thus avoiding inconsistent quality.

[0033] Specifically, such as Figure 2 As shown, an arc panel 6 is fixedly connected to the top of the support frame 32.

[0034] Specifically, such as Figure 2 As shown, sensing valves 7 are fixedly connected to the top and bottom of the inside of the premix tank 31.

[0035] In this embodiment, the premix tank 31 is equipped with sensing valves 7 at the top and bottom to adjust its sealing state to the upper and lower pipeline systems, and the arc panel 6 can prevent materials from accumulating on the surface of the support frame 32.

[0036] Working principle: When quantitatively dispensing and packaging vitamin E premix, a quantitative weighing and packaging machine 1 is usually used. The premix is ​​transported to the quantitative weighing and packaging machine 1 through the pipeline conveying structure at the top of the workshop and weighed. Then, it is discharged through the discharge port at the bottom of the quantitative weighing and packaging machine 1 into the tank conveyed by the conveyor belt or into the packaging bag held by the personnel to complete the quantitative packaging. However, in the above process, the premix first needs to go through a long transfer section and a complex path in the pipeline transmission system, which destroys its premixed state and makes its unit homogeneity low. As a result, the quality is inconsistent after quantitative packaging.Secondly, the quantitative weighing and packaging machine 1 mainly relies on the weighing system to achieve the effect of quantitative material discharge and packaging. If the feeding speed is uniform, a relatively stable quantitative quantity can be achieved. However, in the existing feeding state that only relies on valve control, the feeding speed may suddenly increase, causing the quantitative weighing and packaging machine 1 to misjudge that the capacity is sufficient and feed material prematurely, resulting in quantitative errors. To avoid the above situation, the pipeline transmission system is divided into an upper transmission pipe 2 and a lower transmission pipe 4 for the feeding section. A premixing tank 31 is set between the upper transmission pipe 2 and the lower transmission pipe 4. The top and bottom of the premixing tank 31 are equipped with sensing valves 7 to adjust its sealing state of the upper and lower pipeline systems. When the upper transmission pipe 2 feeds material, it first enters the interior of the premixing tank 31 and is premixed. After a certain amount of material accumulates inside the mixing tank 31, the servo motor 33 located inside the premixing tank 31 is activated, causing the support shaft 34, located at the output end of the servo motor 33 and rotatably connected to the center of the support frame 32, to rotate. When the support shaft 34 rotates, spiral stirring rollers 3503, mounted on a support structure composed of support blocks 3501 and rotating blocks 3502, are mounted on both sides of it. During transmission, the spiral stirring rollers 3503 are subjected to stirring contact force and rotational force, resulting in a certain degree of rotation that agitates the internal material, thus achieving a premixing effect. To further enhance mixing efficiency, an electronic telescopic rod 3504 is also provided between the rotating block 3502 and the support shaft 34. The two ends of the electronic telescopic rod 3504 are rotatably connected to… At the bottom of the rotating block 3502 and on the outside of the supporting shaft 34, when the electronic telescopic rod 3504 reciprocates, it pulls the rotating block 3502 to rotate reciprocally along the outer wall of the supporting block 3501, and drives the spiral stirring roller 3503 to perform more complex reciprocating oscillation and stirring. During this process, it also tumbles through rotation, achieving a second mixing effect before directly feeding into the lower transmission pipe 4, thus avoiding inconsistent quality. Furthermore, after the material is mixed again, upon entering the discharge transmission pipe and reaching the discharge port, it is not discharged directly. Instead, it is blocked and accumulated in small quantities by the double baffle plate 52 inside the bottom support box 51, gradually reducing the blocking area to control the flow rate. This is achieved by starting the stepper motor 55. This allows the drive gear 56 located at the output end of the stepper motor 55 to rotate. The drive gear 56 drives the linkage gear ring 54 meshing with its outer side. The linkage gear ring 54 has outward teeth that mesh with the drive gear 56 and has an arc-shaped guide groove inside. Linkage columns 53 are provided on the inner side of each guide groove. Since the linkage columns 53 are fixedly connected to the baffle plate 52, the linkage of the linkage gear ring 54 can drive the double baffle plate 52 to slide slowly to both sides, reducing the baffle area. This allows the premixed material to enter the quantitative weighing and packaging machine 1 at a uniform and slow speed. Furthermore, the feeding speed can be adjusted according to the speed and size, thus avoiding the problem of unstable feeding speed relying solely on the valve. In summary, this optimizes the quantitative dispensing and packaging machine for vitamin E premixed material.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
