Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of packaging machinery and equipment, and relates to a weighing hopper structure. Background Technology
[0002] Material packaging has a wide range of applications in production, and ensuring the quantitative packaging of bags is a key concern for enterprises. Materials are usually weighed using a weighing packaging machine. The weighing process uses intermittent feeding, meaning that once the material in the lower weighing cylinder reaches the bagging weight, the upper hopper valve closes, stopping the feeding. During the closing process of the hopper valve, the material falling during the process is thrown outside the weighing packaging machine, causing material to splash inside the workshop and resulting in material loss. Summary of the Invention
[0003] To address the aforementioned problems, this utility model provides a weighing hopper structure that effectively gathers materials during the closing of the discharge valve, preventing materials from splashing into the workshop.
[0004] According to the technical solution of this utility model: a weighing hopper structure, characterized in that: it includes a weighing cylinder and a feeder disposed on the top of the weighing cylinder, and a feeder drive motor is installed on one side of the feeder to drive the feeder discharge valve to rotate and control the opening and closing of the lower discharge end of the feeder.
[0005] The top of the weighing cylinder is equipped with a baffle corresponding to the closed side of the discharge valve of the feeder. The lower part of the baffle is engaged with the frame plate at the top of the feeder and fixed with bolts. The upper part of the baffle has a gathering part so that when the discharge valve of the feeder is closed, the material blocked by the discharge valve of the feeder is gathered and falls into the weighing cylinder.
[0006] As a further improvement of this utility model, the bottom surface of the lower discharge end of the feeder is arc-shaped, and the output shaft of the feeder drive motor extends through the inner cavity of the feeder to the other side of the feeder.
[0007] The discharge valve of the feeder includes two parallel side plates, which are respectively located on both sides of the feeder and fixedly connected to the output shaft of the feeder. A gate plate is fixedly connected between the two side plates, and the gate plate is arc-shaped.
[0008] As a further improvement of this utility model, a weighing cylinder opening and closing door is hinged to each side of the discharge end of the weighing cylinder, and the two weighing cylinder opening and closing doors cooperate with each other to realize the opening and closing adjustment of the discharge end of the symmetrical cylinder.
[0009] As a further improvement of this utility model, a cylinder is installed on the side of the weighing cylinder, and the piston rod of the cylinder is connected to a horizontal plate. A connecting rod is hinged to each end of the horizontal plate along its length. The connecting rod is hinged to the corresponding opening and closing door leaf, thereby realizing the opening and closing action of the opening and closing door leaf driven by the connecting rod.
[0010] As a further improvement of this utility model, a hydraulic buffer is provided on the side of the weighing cylinder, and the piston end of the hydraulic buffer abuts against the horizontal plate.
[0011] As a further improvement of this utility model, the gathering part and the baffle are bent toward the feeder side, and there is a gap between the gathering part and the side wall of the feeder.
[0012] As a further improvement of this utility model, the lower part of the feeder has a shape that is wide at the top and narrow at the bottom.
[0013] As a further improvement of this utility model, two grooved plates are welded to the back of the baffle along the length direction, and each grooved plate and the baffle respectively form a slot.
[0014] The technical advantages of this utility model are as follows: The product has a reasonable and ingenious structure. By setting a baffle structure at the top of the weighing cylinder corresponding to the closed side of the discharge valve of the feeder, it can collect the material that is thrown away by the discharge valve when it is closed back into the weighing cylinder, preventing material from splashing into the workshop. Furthermore, the baffle can reliably collect the material. In addition, the discharge valve of the feeder in this application can reliably fit against the discharge end of the feeder, ensuring that the discharge end of the feeder can be reliably closed.

[0016] Figure 2 for Figure 1 The left view. Detailed Implementation
[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0019] Figure 1 ,2 The components include a feeder 1, a baffle 2, a weighing cylinder 3, a cylinder 4, a connecting rod 5, a weighing cylinder opening and closing door 6, a feeder discharge valve 7, a feeder drive motor 8, and a hydraulic buffer 9.
[0020] like Figure 1 , 2 As shown, this utility model is a weighing hopper structure, including a weighing cylinder 3 and a feeder 1 that is disposed on the top of the weighing cylinder 3. In specific production practice, the feeder 1 can be fixed above the weighing cylinder 3 by a support column.
[0021] A feeder drive motor 8 is installed on one side of the feeder 1 to drive the feeder discharge valve 7 to rotate and control the opening and closing of the lower discharge end of the feeder 1.
[0022] A baffle 2 is installed at the top of the weighing cylinder 3, corresponding to the closed side of the discharge valve 7 of the feeder. The lower part of the baffle 2 has a slot 2-1 that is engaged with the frame plate at the top of the feeder 1 and fixed with bolts. The upper part of the baffle 2 has a gathering part 2-2 to gather the material blocked by the discharge valve 7 of the feeder when it is closed and let it fall into the weighing cylinder 3. The length of the baffle 2 is greater than the length of the outer wall of the feeder 1.
[0023] The bottom surface of the lower discharge end of the feeder 1 is arc-shaped, and the output shaft of the feeder drive motor 8 extends through the inner cavity of the feeder 1 to the other side of the feeder 1.
[0024] The discharge valve 7 of the feeder includes two parallel side plates, which are respectively located on both sides of the feeder 1 and fixedly connected to the output shaft of the feeder 1. A gate plate is fixedly connected between the two side plates, and the gate plate is arc-shaped.
[0025] A weighing cylinder opening and closing gate 6 is hinged to each side of the discharge end of the weighing cylinder 3. The two weighing cylinder opening and closing gates 6 cooperate with each other to achieve the opening and closing adjustment of the discharge end of the symmetrical cylinder 3.
[0026] A cylinder 4 is installed on the side of the weighing cylinder 3. The piston rod of the cylinder 4 is connected to a horizontal plate. A connecting rod 5 is hinged to each end of the horizontal plate along its length. The connecting rod 5 is hinged to the corresponding opening and closing door 6, thereby realizing the opening and closing action of the opening and closing door 6 driven by the connecting rod 5.
[0027] A hydraulic buffer 9 is provided on the side of the weighing drum 3, and the piston end of the hydraulic buffer 9 abuts against the horizontal plate. In this way, when the weighing drum door 6 is closed, the hydraulic buffer 9 can reliably buffer the opening and closing of the weighing drum door 6, and avoid large noise caused by collision when the weighing drum door 6 is closed.
[0028] The gathering part 2-2 and the baffle 2 are bent toward the feeder 1, and there is a gap between the gathering part 2-2 and the side wall of the feeder 1.
[0029] like Figure 1 As shown, the lower part of the feeder 1 has a shape that is wide at the top and narrow at the bottom, which can reliably guide the material to fall. At the same time, the top of the feeder 1 is constructed with a conical hopper.
[0030] Two slotted plates are welded along the length of the back of the baffle 2, and each slotted plate forms a slot 2-1 with the baffle 2.
[0031] like Figure 1 , 2 As shown, in operation, the material to be weighed enters the inner cavity of the feeder 1 through the feed inlet at the top. The feeder drive motor 8 drives the feeder discharge valve 7 to open, allowing the feeder 1 to feed material into the weighing cylinder 3 below. When the weight of the material in the weighing cylinder 3 reaches the set value, the feeder drive motor 8 drives the feeder discharge valve 7 to rotate, closing the lower discharge port of the feeder 1. Since the feeder 1 is discharging material, the feeder discharge valve 7 pushes the material outward during the closing process. At this time, due to the action of the baffle 2, the material is blocked by the baffle 2, thus preventing the material from falling into the weighing cylinder 3. To prevent the material from being ejected outward after hitting the baffle 2, a gathering part 2-2 is also provided on the upper part of the baffle 2. The gathering part 2-2 reliably gathers and blocks the material, thus gathering the material into the weighing cylinder 3. The cylinder opening and closing action is performed by the cylinder opening and closing door 6 driven by the cylinder 4 and connecting rod 5 installed outside the weighing cylinder 3. The two weighing cylinder opening and closing gates 6 can be opened and closed independently through a connecting rod 5, so as to reliably adjust the opening and closing amplitude of the symmetrical cylinder 3 to meet the working requirements.
[0032] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
