Description

Technical Field

[0001] This utility model belongs to the field of food production technology, and in particular relates to a quantitative feeding device. Background Technology

[0002] In current food production processes, especially in the processing of batter-based products, traditional methods rely on manual operation or the use of screw pumps for feeding. However, these methods have significant limitations. While screw pump feeding can achieve a degree of automation, poor sealing at the discharge port often leads to overflow, resulting in instability in product weight. Furthermore, for batter-based products with high viscosity and poor flowability, the efficiency and adaptability of screw pumps face challenges, making it difficult to ensure smooth material flow and maintain a stable flow rate and precise weight control.

[0003] On the other hand, relying entirely on manual cutting is not only inefficient, but also makes it difficult to guarantee the weight consistency of each product due to human factors, posing a severe challenge to quality control. Simultaneously, with the continuous rise in labor costs, the cost-effectiveness of this traditional method is gradually decreasing. Therefore, the market urgently needs an automated solution that can replace manual operation, effectively handle the characteristics of viscous materials, and achieve high-precision quantitative feeding. This is precisely the core problem that this invention aims to solve, providing a highly efficient, stable, and easily adjustable quantitative feeding device to meet the stringent requirements of modern food industry for product quality and production efficiency.

[0005] This utility model is implemented as follows: a quantitative feeding device includes a second fixed plate; a cylinder fixing plate is provided above the second fixed plate, and a column is fixed between the second fixed plate and the cylinder fixing plate; a first fixed plate is installed on the second fixed plate, and a hopper is fixed on the first fixed plate; a feeding cylinder is installed and fixed on the cylinder fixing plate, and a feeding piston rod that cooperates with the hopper is installed and fixed at the end of the telescopic spindle of the feeding cylinder; the feeding cylinder drives the feeding piston rod to reciprocate within the hopper to achieve quantitative feeding; a ball valve is installed at the bottom outlet of the hopper, and a connecting plate is fixed on the ball valve; a third fixed plate is fixed at the bottom of the second fixed plate, and a control cylinder is hinged between the third fixed plate and the connecting plate; the control cylinder drives the ball valve to open or close to cooperate with the feeding action of the feeding piston rod.

[0006] In a further technical solution, the column is provided as two, and the hopper is located between the two columns.

[0007] In a further technical solution, when the feeding cylinder controls the feeding piston rod to rise, the control cylinder drives the ball valve to close; when the feeding cylinder controls the feeding piston rod to fall, the control cylinder drives the ball valve to open, and the material in the hopper is squeezed out from the ball valve under the pressure of the feeding piston rod.

[0008] In a further technical solution, the feeding cylinder is a stroke-adjustable cylinder. By adjusting the stroke of the feeding cylinder, the movement distance of the feeding piston rod can be controlled, thereby adjusting the single feeding amount.

[0009] The quantitative feeding device provided by this utility model has the following beneficial effects:

[0010] This invention combines piston-type quantitative feeding with ball valve-type discharge control, achieving precise control of the material feeding weight, significantly reducing manual intervention and lowering production costs.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] like Figure 1As shown, a quantitative feeding device according to an embodiment of the present invention includes a second fixed plate 6, a cylinder fixing plate 2 above the second fixed plate 6, a column 4 fixed between the second fixed plate 6 and the cylinder fixing plate 2, a first fixed plate 5 also installed on the second fixed plate 6, a hopper 3 fixed on the first fixed plate 5, a feeding cylinder 1 fixed on the cylinder fixing plate 2, and a feeding piston rod 11 cooperating with the hopper 3 fixed at the end of the telescopic spindle of the feeding cylinder 1. When the feeding cylinder 1 extends and retracts, the feeding piston rod 11 moves up and down together. The feeding cylinder 1 can be a stroke-adjustable cylinder. By adjusting the stroke of the feeding cylinder 1, the movement distance of the feeding piston rod 11 can be controlled, thereby adjusting the single feeding amount.

[0017] A ball valve 8 is installed at the bottom outlet of the hopper 3. A connecting plate 7 is fixed on the ball valve 8. A fixing plate 10 is also fixed at the bottom of the fixing plate 6. A control cylinder 9 for controlling the ball valve 8 is hinged between the fixing plate 10 and the connecting plate 7. The control cylinder 9 controls the opening and closing of the ball valve 8 when it extends and retracts.

[0018] In a preferred embodiment of this utility model, there are two columns 4, and the hopper 3 is located between the two columns 4.

[0019] In a preferred embodiment of this utility model, the cylinder fixing plate 2 can be fixed to the main body of the device; the fixing plate 2 6 and the fixing plate 5 are fastened by screws, and the fixing plate 2 6 can be connected to the main body by supporting parts, thereby realizing the installation and fixing of the quantitative feeding device.

[0020] In a preferred embodiment of this utility model, when the feeding cylinder 1 controls the feeding piston rod 11 to rise, the ball valve 8 is closed; when the feeding cylinder 1 controls the feeding piston rod 11 to fall, the ball valve 8 is opened. At this time, the slurry will be squeezed out from the ball valve 8 by the pressure of the feeding piston. The feeding amount can be controlled by adjusting the stroke of the feeding cylinder 1, and the ball valve 8 can also be replaced according to different feeding amounts to achieve more precise weight control.

[0021] Furthermore, the control of each component can be achieved using a PLC controller disclosed in the existing technology. There are no specific limitations on the model and circuit connection of each component, and they can be flexibly configured in practical applications.

[0022] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0023] The present invention provides a quantitative feeding device in the above embodiments. By setting up a cooperative structure between the hopper 3 and the feeding piston rod 11, the feeding cylinder 1 drives the feeding piston rod 11 to reciprocate within the hopper 3, thereby achieving piston-type feeding of materials by pushing them forward. This method can effectively improve the stability and consistency of feeding, avoid material blockage or flow interruption, and ensure continuous and controllable discharge process.

[0024] The telescopic spindle of the feeding cylinder 1 is fixedly connected to the feeding piston rod 11. By adjusting the stroke of the feeding cylinder 1, the movement distance of the feeding piston rod 11 can be precisely controlled, thereby achieving quantitative feeding. At the same time, this structure also supports replacing the feeding cylinder 1 with a motor drive system, improving the adaptability and control accuracy of the device and meeting the automation needs under different working conditions.

[0025] A ball valve 8 is installed at the bottom outlet of the silo 3, and its diameter directly affects the discharge rate per unit time. By replacing the ball valve 8 with one of different diameters or materials, the discharge rate can be flexibly adjusted according to the material characteristics (such as viscosity and particle size) or the required discharge weight, significantly improving the versatility and discharge accuracy of the device.

[0026] Ball valve 8 is hinged to control cylinder 9 via connecting plate 7. Control cylinder 9 is mounted on fixed plate 10, and its extension and retraction movement drives ball valve 8 to achieve on / off control. This linkage structure ensures precise timing of the feeding action—when the feeding piston rod 11 rises, ball valve 8 closes to prevent dripping; when the feeding piston rod 11 falls, ball valve 8 opens, and material is smoothly extruded under piston pressure. This design can also replace control cylinder 9 with a motor-driven mechanism to further improve control flexibility.

[0027] In summary, this invention combines piston-type quantitative feeding with ball valve-type discharge control to achieve precise control of the material feeding weight, significantly reducing manual intervention and lowering production costs. Simultaneously, the modular design allows for quick replacement of key components such as the ball valve 8, facilitating maintenance and cleaning. It is suitable for automated quantitative feeding scenarios of various materials, demonstrating good practicality and promotional value.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
