Description

Technical Field

[0001] The utility model relates to the technical field of food packaging, in particular to an automatic food quantitative packaging device. Background Art

[0002] There are many ways to package quantitatively, some use weighing, and some use fixed volume packaging. For some lightweight products, the weighing method requires high precision of symmetry. A slight error will result in a large difference in product volume. At the same time, due to the high cost of scales, the cost of packaging equipment is also high if multiple high-precision scales are designed in the packaging equipment. The fixed volume packaging method is to convert the volume and mass in advance according to the actual situation of the product, and use the fixed volume packaging method, which has lower equipment costs.

[0003] Currently, a Chinese utility model patent application with publication number CN216762229U proposes an automated food quantitative packaging device, comprising a cylinder, a turntable, and a feed pipe. Several through-holes are provided along the circumference of the upper surface of the turntable, each of which is inserted with a quantitative cylinder. A feed hole is provided on the bottom surface of the cylinder on a side away from the feed pipe, which is communicable with the quantitative cylinder passing above it. A material diverter mechanism is installed on the side wall of the cylinder, which diverts material overflowing from the upper port of the quantitative cylinder passing below it onto the turntable. The height of the material diverter mechanism relative to the upper port of the quantitative cylinder is adjustable. A discharge port is provided on one side of the bottom of the cylinder, and a discharge mechanism is provided inside the discharge port, which discharges material on the turntable from the discharge port. This utility model ensures that the materials filled in each quantitative cylinder are essentially equal, achieving quantitative processing, and can control the error in gram count within a very small range, achieving automated packaging, and meeting different quantitative processing requirements.

[0004] However, in the above structure, most of the materials will fall onto the turntable under the action of gravity or the movement of the material-dispensing mechanism during the unloading process, and will be discharged through the discharging mechanism. Therefore, during the unloading process, only a small part of the materials will fall into the cylinder under the action of gravity for quantitative processing. Most of the materials cannot be quantitatively processed at one time, and the work efficiency is low. Utility Model Content

[0005] The utility model provides an automatic food quantitative packaging device, which can improve the technical problem in the related art that the existing automatic food quantitative packaging device cannot quantitatively process most of the materials in the cylinder at one time and has low working efficiency.

[0006] The present invention provides an automated food quantitative packaging device, comprising:

[0007] Silos, packaging components, butterfly valve components and receiving mechanisms;

[0008] The packaging assembly includes a turntable, a plurality of metering cylinders and a baffle. The turntable is rotatably installed in the silo. The plurality of metering cylinders are arranged at the bottom of the turntable and distributed around the turntable in a circular array. A through hole is opened on the turntable, and the through hole is connected to the inner cavity of the metering cylinder. The baffle is arranged in the silo and slidably fits with the top wall of the turntable. A discharge port is opened at the bottom of the silo.

[0009] The butterfly valve assembly is used to open and close the bottom opening of the metering cylinder;

[0010] The receiving mechanism is used for receiving food that falls out of the silo.

[0011] The above technical solutions in the embodiments of the present application have at least the following technical effects:

[0012] When food needs to be quantitatively packaged, the food is first placed on the turntable in the hopper and the turntable is rotated. The food moves to the edge of the turntable under the action of centrifugal force and falls into multiple quantitative cylinders with the help of the baffle. The turntable continues to rotate. After each quantitative cylinder is full of food, the turntable continues to rotate. When the quantitative cylinder moves to the discharge port, the baffle has blocked the excess product at the top opening of the quantitative cylinder and is in contact with the top wall of the through hole of the turntable, making it difficult for the food in the hopper to enter the inner cavity of the quantitative cylinder. The butterfly valve assembly is started to open the bottom opening of the quantitative cylinder, and the quantitative food in the quantitative cylinder falls onto the receiving mechanism for automatic packaging. The quantitative food in each subsequent quantitative cylinder can fall onto the receiving mechanism in the above manner for automatic packaging. By analogy, most of the materials in the hopper can be quantitatively discharged and packaged; this solves the technical problem that the existing automated food quantitative packaging equipment cannot quantitatively process most of the materials in the cylinder at one time and has low working efficiency.

[0013] In some embodiments, a push plate is provided on the inner wall of the silo, and one end of the push plate away from the inner wall of the silo is tilted along the direction of rotation close to the turntable.

[0014] In some embodiments, the bottom of the metering cylinder is slidably fitted with the inner bottom wall of the silo.

[0015] In some embodiments, a first motor is provided at the bottom of the silo, and an output end of the first motor is sealed through the bottom wall of the silo and is transmission-connected to the turntable.

[0016] In some embodiments, a plurality of limiting rings are provided on the inner bottom wall of the silo, and both sides of the metering cylinder are slidably fitted with the side walls of the limiting rings.

[0017] In some embodiments, a side surface of the baffle is tilted to form a guide surface.

[0018] In some embodiments, the butterfly valve assembly includes a valve disc, a valve stem and a second motor. The second motor is arranged on the metering cylinder. One end of the valve stem is rotatably connected to the output end of the second motor, and the other end is sealed through the side wall of the metering cylinder and fixedly connected to the valve disc.

[0019] In some embodiments, the receiving mechanism includes a frame, multiple conveying shafts, a conveyor belt, a third motor and multiple boxes. The multiple conveying shafts are rotatably installed on both sides of the frame. The multiple conveying shafts are sleeved with conveyor belts. The third motor is arranged on the frame. The output end of the third motor is transmission-connected to the conveying shaft on one side of the frame. The box is placed on the conveyor belt.

[0020] In summary, the present invention has at least one of the following beneficial technical effects:

[0021] 1. A first motor is used to control the rotation of the turntable, so that the food falls into the metering cylinder under the action of centrifugal force. When the metering cylinder moves to the discharge port, a baffle is used to block excess products, and the butterfly valve assembly is started to open the bottom opening of the metering cylinder. The quantitative food in the metering cylinder falls onto the receiving mechanism for automatic packaging. Similarly, most of the materials in the silo can be quantitatively discharged and packaged. This solves the technical problem that existing automatic food quantitative packaging equipment cannot quantitatively process most of the materials in the cylinder at one time and has low working efficiency.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0031] Based on this, the technical problem that the existing automated food quantitative packaging equipment in the relevant technology cannot quantitatively process most of the materials in the cylinder at one time and has low working efficiency can be improved. The embodiment of this application provides the following solution.

[0032] Please also refer to Figures 1 to 5 , the embodiment of the present application provides an automated food quantitative packaging device, including a silo 10, a packaging assembly 20, a butterfly valve assembly 30 and a receiving mechanism 40;

[0033] The packaging assembly 20 includes a turntable 21, a plurality of metering cylinders 22, and a baffle 23. The turntable 21 is rotatably mounted in the silo 10. The plurality of metering cylinders 22 are disposed at the bottom of the turntable 21 and are distributed in a circular array around the turntable 21. A through hole 211 is formed on the turntable 21, and the through hole 211 communicates with the inner cavity of the metering cylinder 22. The baffle 23 is disposed in the silo 10 and slidably fits against the top wall of the turntable 21. A discharge port 11 is formed at the bottom of the silo 10.

[0034] The butterfly valve assembly 30 is used to open and close the bottom opening of the metering cylinder 22;

[0035] The receiving mechanism 40 is used to receive food that falls out of the silo 10 .

[0036] As can be seen from the above, when quantitative packaging of food is required, the food is first placed on the turntable 21 in the silo 10, and the turntable 21 is rotated. The food moves to the edge of the turntable 21 under the action of centrifugal force, and falls into multiple quantitative cylinders 22 with the blocking of the baffle 23. The turntable 21 is continued to be rotated. After each quantitative cylinder 22 is filled with food, the turntable 21 is continued to be rotated. When the quantitative cylinder 22 moves to the discharge port 11, the baffle 23 has blocked the excess product at the top opening of the quantitative cylinder 22 and is in contact with the top wall of the through hole 211 of the turntable 21, making it difficult for food in the silo 10 to enter. In the inner cavity of the metering cylinder 22, the butterfly valve assembly 30 is started to open the bottom opening of the metering cylinder 22, and the quantitative food in the metering cylinder 22 falls onto the receiving mechanism 40 for automatic packaging. The quantitative food in each subsequent metering cylinder 22 can fall onto the receiving mechanism 40 in the above manner and be automatically packaged. By analogy, most of the materials in the silo 10 can be quantitatively discharged and packaged. This solves the technical problem that the existing automatic food quantitative packaging equipment cannot quantitatively process most of the materials in the cylinder at one time and has low working efficiency.

[0037] Optionally, in some embodiments, see Figures 1 to 2 The receiving mechanism 40 includes a frame 41, multiple conveying shafts 42, a conveyor belt 43, a third motor 44 and multiple boxes 45. The multiple conveying shafts 42 are rotatably installed on both sides of the frame 41. The multiple conveying shafts 42 are sleeved with conveyor belts 43. The third motor 44 is set on the frame 41. The output end of the third motor 44 is transmission-connected to the conveying shaft 42 on one side of the frame 41. The box 45 is placed on the conveyor belt 43.

[0038] With such a configuration, the third motor 44 is started, the conveyor shaft 42 rotates, and the conveyor belt 43 is driven to transmit, so that multiple boxes 45 can be transported. When the box 45 moves to below the discharge port 11, the third motor 44 controls the conveyor shaft 42 to stop rotating. After the packaging component 20 controls the quantitative drop of food into the box 45, the third motor 44 controls the conveyor shaft 42 to rotate, and performs material receiving and conveying operations on the subsequent boxes 45. The operation is simple and convenient, and the degree of automation of the equipment is improved.

[0039] Optionally, in some embodiments, see Figures 2 to 4 A push plate 12 is provided on the inner wall of the silo 10 , and one end of the push plate 12 away from the inner wall of the silo 10 is tilted along the direction of rotation close to the turntable 21 .

[0040] With such arrangement, during the rotation of the turntable 21, the food moves toward the edge of the turntable 21 under the action of centrifugal force. When the food at the edge contacts the pushing plate 12, the food falls into the metering cylinder 22 under the obstruction of the pushing plate 12. The end of the pushing plate 12 away from the inner wall of the silo 10 is tilted along the direction of rotation of the turntable 21, so that the food between the through hole 211 and the edge of the turntable 21 falls into the metering cylinder 22 through the through hole 211 under the push of the tilted pushing plate 12, so that almost all the materials in the silo 10 can be quantitatively discharged and packaged, thereby improving work efficiency.

[0041] Optionally, in some embodiments, see Figures 2 to 3 The bottom of the metering cylinder 22 is slidably fitted with the inner bottom wall of the silo 10 .

[0042] With such an arrangement, when the metering cylinder 22 moves to the discharge port 11 and discharges the food through the butterfly valve assembly 30, the bottom of the metering cylinder 22 slides and fits against the inner bottom wall of the silo 10, thereby reducing the probability of food falling into the gap between the metering cylinder 22 and the inner bottom wall of the silo 10 during the discharge process.

[0043] Optionally, in some embodiments, see Figures 1 to 4 A first motor 24 is provided at the bottom of the silo 10 , and an output end of the first motor 24 is sealed and passes through the bottom wall of the silo 10 and is transmission-connected to the turntable 21 .

[0044] In this way, the first motor 24 is provided to facilitate the staff in controlling the rotation of the turntable 21 .

[0045] Optionally, in some embodiments, see Figure 3 A plurality of limiting rings 13 are provided on the inner bottom wall of the silo 10 , and both sides of the metering cylinder 22 are slidably fitted with the side walls of the limiting rings 13 .

[0046] With such arrangement, when the metering cylinder 22 revolves along the turntable 21 , both sides of the metering cylinder 22 slide and fit with the side walls of the limiting ring 13 , making it difficult for the metering cylinder 22 to shake during movement.

[0047] Optionally, in some embodiments, see Figure 4 One side surface of the baffle 23 is tilted to form a guide surface 231 .

[0048] With this arrangement, the guide surface 231 is tilted along the direction of rotation of the turntable 21. During the rotation of the turntable 21, the food moves toward the edge of the turntable 21 under the action of centrifugal force. When the food at the edge contacts the guide surface 231, the food is pushed by the guide surface 231 through the through hole 211 and falls into the metering cylinder 22, so that almost all the materials in the silo 10 can be quantitatively discharged and packaged, thereby improving work efficiency.

[0049] Optionally, in some embodiments, see Figure 5 The butterfly valve assembly 30 includes a valve disc 31, a valve stem 32 and a second motor 33. The second motor 33 is arranged on the metering cylinder 22. One end of the valve stem 32 is rotatably connected to the output end of the second motor 33, and the other end is sealed through the side wall of the metering cylinder 22 and fixedly connected to the valve disc 31.

[0050] With this arrangement, when the second motor 33 is started, the valve stem 32 drives the valve flap 31 to rotate, thereby opening or closing the metering cylinder 22 , making it convenient for the staff to control the opening and closing of the bottom opening of the metering cylinder 22 .

[0051] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
