Description

Technical Field

[0001] The utility model relates to the technical field of granular material feeding metering, and particularly relates to a measuring cup for granular material feeding metering. Background Art

[0002] An automatic packaging machine is an increasingly mature automated production equipment in modern industry. People often come into contact with items with packaging bags in daily life, ranging from large appliances to small items such as salt and seasonings. In the field of automatic packaging machines, quantitative packaging is often required for packaging fine granular materials, and packaging is carried out with a definite weight and volume. Among them, a measuring cup is a commonly used metering and feeding structure for packaging machines. The existing measuring cups for metering and feeding usually cooperate with a cover plate arranged at the discharge port of the measuring cup through a cylinder. The cylinder drives the cover plate to rotate around a hinge shaft to realize the automatic opening and closing of the discharge port.

[0003] However, due to processing errors and the problem of the cylinder stroke, the sealing performance between the cover plate and the discharge port is not good. The cover plate cannot completely seal and fit the discharge port, and there is a gap between the two. Also, since the particle size of granular materials is generally small, it will directly cause material leakage, thereby affecting the metering and feeding accuracy of the measuring cup. Summary of the Invention

[0004] In order to solve the problems and deficiencies existing in the above-mentioned prior art, the utility model provides a measuring cup for granular material feeding metering. An elastic component with elastic deformation is arranged between the cover plate and the swing arm of the utility model. The cover plate can not only rotate with the swing arm to open and close the discharge port, but also further rotate relative to the swing arm with the elastic deformation of the elastic component, so as to be hermetically fitted with the discharge port of the measuring cup body. The utility model ensures the sealing performance of the measuring cup discharge port when it is closed.

[0005] In order to achieve the above-mentioned invention purpose, the technical solution of the utility model is as follows:

[0006] A measuring cup for granular material feeding metering includes a measuring cup body. A discharge port is arranged at the bottom of the measuring cup body. A cover plate and a swing arm are arranged at the position of the discharge port. The swing arm is connected with a driving mechanism for driving its rotation. One end of the cover plate is rotatably connected with the swing arm, and an elastic component capable of generating elastic deformation is arranged between the other end and the swing arm. The cover plate rotates with the swing arm to open and close the discharge port, and when the elastic component undergoes elastic deformation, the cover plate rotates relative to the swing arm with the elastic deformation of the elastic component and is hermetically fitted with the discharge port of the measuring cup body.

[0007] As a preferred embodiment of the present utility model, the elastic component includes a first spring column and a first spring sleeved on the first spring column. One end of the first spring column is fixedly connected to the cover plate, and the other end is movably arranged in the kidney-shaped hole of the swing arm. One end of the first spring abuts against the cover plate, and the other end abuts against the swing arm.

[0008] As a preferred embodiment of the present utility model, the tail of the first spring column is provided with a pin to prevent the first spring column from disengaging from the kidney-shaped hole.

[0009] As a preferred embodiment of the present utility model, the cover plate is rotatably connected to the swing arm through a second spring column, and a second spring is sleeved on the second spring column.

[0010] As a preferred embodiment of the present utility model, the rotation connection points of the elastic component with the cover plate and the swing arm are located on the same straight line along the length direction of the cover plate.

[0011] As a preferred embodiment of the present utility model, the driving mechanism includes a cylinder, the cylinder is fixed on the outer wall of the measuring cup body, and the swing arm is respectively hinged to the piston rod of the cylinder and the outer wall of the measuring cup body.

[0012] Advantages of the present utility model:

[0013] (1) An elastic component is assembled between the cover plate and the swing arm of the measuring cup body of the present utility model. Due to processing errors and the stroke of the cylinder, there is a problem that the cover plate cannot completely seal the discharge port. Therefore, when the driving mechanism drives the cover plate to rotate towards the discharge port to close the discharge port, under the action of the elastic component, the cover plate further rotates towards the discharge port relative to the swing arm, so that the cover plate is completely sealed and attached to the discharge port of the measuring cup body, thus ensuring the sealing performance during closing.

[0014] (2) The rotation connection points of the elastic component of the present utility model with the cover plate and the swing arm are located on the same straight line along the length direction of the cover plate, and the two form a line contact on the same straight line on the cover plate, making the sealing and attaching effect between the cover plate and the discharge port better.

[0021] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will further illustrate the technical solutions for achieving the invention purpose of the present utility model through several specific embodiments. It should be noted that the technical solutions claimed by the present utility model include but are not limited to the following embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment 1

[0023] This embodiment discloses a measuring cup for metering the feeding of granular materials. Referring to the attached drawings of the specification Figures 1-3 As shown, the measuring cup includes a measuring cup body 1 with openings at both the top and bottom. The upper opening of the measuring cup body 1 is the feeding port, and the bottom opening is the discharging port. At the position of the discharging port, there is a cover plate 2 for opening and closing the discharging port. The cover plate 2 is connected with a driving mechanism 3. The driving mechanism 3 includes a cylinder 301 and a swing arm 302. The cylinder 301 is fixed on the outer wall of the measuring cup body 1. The swing arm 302 is respectively hinged to the piston rod of the cylinder 301 and the outer wall of the measuring cup body 1. The cover plate 2 is connected with the swing arm 302. The cylinder 301 drives the swing arm 302 to rotate around the hinge point of the two. The cover plate 2 connected with the swing arm 302 rotates together with the swing arm 302, and the cover plate 2 automatically opens or closes the discharging port of the measuring cup body 2. Further, the cover plate 2 is hinged to the swing arm 302, and an elastic component 4 is also assembled between the cover plate 2 and the swing arm 302. The elastic component 4 can generate elastic deformation. When the elastic component 4 undergoes elastic deformation, the cover plate 2 can rotate relative to the swing arm 302 along with the deformation of the elastic component 4 (rotate around the hinge point of the two, and the rotation direction is towards the discharging port of the measuring cup body 1), so as to be completely sealed and fitted with the discharging port of the measuring cup body 1.

[0024] In the embodiment depicted by the present utility model, a feeding device is provided above the measuring cup. The feeding device feeds granular materials into the measuring cup. Then, the air cylinder 301 drives the swing arm 302 rotatably connected thereto to rotate away from the discharge port. The swing arm 302 drives the cover plate 2 connected thereto to move together, opening the discharge port of the measuring cup. The granular materials in the measuring cup fall into the packaging bag below. Next, the air cylinder 301 drives the swing arm 302 to rotate and reset towards the discharge port. Similarly, the swing arm 302 drives the cover plate 2 connected thereto to rotate together, finally closing the discharge port of the measuring cup. When the cover plate 2 is reset, under the action of the discharge port of the measuring cup, the elastic component 4 provided between the cover plate 2 and the swing arm 302 undergoes elastic deformation. The elastic force corresponding to this elastic deformation acts on the cover plate 2, pushing it to rotate relative to the swing arm 302 around the hinge point of the two towards the discharge port, so that the cover plate 2 is completely sealed and fitted with the discharge port of the measuring cup, ensuring the sealing performance at the discharge port when the measuring cup is in the closed state and also guaranteeing the metering accuracy during the feeding of the measuring cup. By continuously performing the above operations, continuous operation of filling granular materials is achieved.

[0025] Embodiment 2

[0026] This embodiment discloses a measuring cup for feeding and metering granular materials. The difference between this embodiment and Embodiment 1 is that the driving mechanism 3 is an electric cylinder, and the electric cylinder drives the swing arm 302 to rotate around the hinge point of the two, thereby driving the cover plate 2 connected to the swing arm 302 to rotate together with the swing arm 302.

[0027] Embodiment 3

[0028] This embodiment discloses a measuring cup for feeding and metering granular materials. On the basis of the above embodiment, the structure of the elastic component 4 is specifically as follows.

[0029] The elastic component 4 includes a first spring column 401 and a first spring 402 sleeved on the first spring column 401. One end of the first spring column 401 is fixedly connected to the cover plate 2, and the other end is movably arranged in the kidney-shaped hole 5 of the swing arm 302. One end of the first spring 402 abuts against the cover plate 2, and the other end abuts against the swing arm 302.

[0030] Further, in order to prevent the first spring column 401 from disengaging from the kidney-shaped hole 5 of the swing arm 302, a pin is installed radially on the first spring column 401. The pin is located at the tail of the end of the first spring column 401 passing through the kidney-shaped hole 5, and the pin abuts against one side of the swing arm 302 to limit the first spring column 401 and prevent it from disengaging from the kidney-shaped hole 6.

[0031] After the granular material in the measuring cup is discharged into the packaging bag, the driving mechanism 3 drives the swing arm 302 to rotate around the hinge point of the two, driving the cover plate 2 connected to the swing arm 302 to rotate towards the discharge port of the measuring cup, and the cover plate 2 closes the discharge port. When the driving mechanism 3 drives the cover plate 2 to reset, the first spring 401 is compressed and elastically deformed, and the spring force of the first spring 401 acts on the cover plate 2, further pushing the cover plate 2 to rotate around the hinge point at the connection with the swing arm 302 relative to the swing arm 302 towards the discharge port of the measuring cup, further adjusting the angle of the cover plate 2, so that the cover plate 2 can be completely sealed and fitted to the discharge port of the measuring cup, ensuring the sealing performance when the discharge port is closed and preventing the leakage of granular materials. Moreover, the tail of the first spring column 401 is movably arranged in the kidney-shaped hole 6. During the process of the cover plate 2 rotating relative to the swing arm 302 around the hinge point connected to the swing arm 302, the first spring column 401 can move freely in the kidney-shaped hole 5, so as to cooperate with the rotation of the cover plate 2 relative to the swing arm 302 and ensure that the cover plate 2 can be sealed and fitted to the discharge port of the measuring cup.

[0032] Embodiment 4

[0033] This embodiment discloses a measuring cup for the metering of granular material discharging. On the basis of the above embodiments, the difference between this embodiment and Embodiment 3 is that the elastic component 4 can also be elastic rubber.

[0034] Embodiment 5

[0035] This embodiment discloses a measuring cup for the metering of granular material discharging. On the basis of the above embodiments, the cover plate 2 is rotatably connected to the swing arm 302 through the second spring column 6. Specifically, one end of the second spring column is fixedly connected to the cover plate 2, and the other end is rotatably connected to the swing arm 302 through a pin shaft. A second spring 7 is also sleeved on the second spring column 6. One end of the second spring 7 abuts against the cover plate 2, and the other end abuts against the swing arm 302. Moreover, the second spring column 7 and the first spring column 401 are distributed on the same straight line along the length direction of the cover plate 2, and the two spring columns form a line contact on the same straight line on the cover plate 2, making the sealing and fitting effect between the cover plate 2 and the discharge port better.
