Description

Technical Field

[0001] The utility model relates to the technical field of wet strength agent production, in particular to an automatic raw material feeding device in the production process of a composite wet strength agent. Background Technique

[0002] Wet strength agents are mainly used in the paper-making industry and are suitable for the production of various papers with wet strength requirements. Due to their characteristics of helping to retain and filter, they can also be used as retention agents and filtration aids in the papermaking process. When producing composite wet strength agents, an automatic raw material feeding device for the production of composite wet strength agents is required.

[0003] For example, an automatic raw material feeding device in the production process of a composite wet strength agent with the authorization announcement number of "CN215506687U" drives a rotating column to rotate through a second motor, so that a first wheel disc and a second wheel disc drive a first transmission chain and a second transmission chain to rotate simultaneously at the same speed. The weighing platform rotates with the transmission chain until it reaches directly above the reaction barrel. A third motor drives the weighing platform to flip 180 degrees, so that the measuring cup is inverted, and the raw materials are put into the reaction barrel. However, when adding solid reagent raw materials into the box body through the feed hopper, the solids are actually easy to block at the bottom of the feed hopper, and the operator needs to manually knock on the feed hopper, which increases the workload of the operator and reduces the working efficiency of the device. When the solid reagent raw materials are put into the box body through the feeding pipe, the weight of the solid reagent raw materials is prone to deviation, which reduces the working quality of the device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when adding solid reagent raw materials into the box body through the feed hopper, the solids are actually easy to block at the bottom of the feed hopper, the operator needs to manually knock on the feed hopper, which increases the workload of the operator and reduces the working efficiency of the device, and when putting the solid reagent raw materials into the box body through the feeding pipe, the weight of the solid reagent raw materials is prone to deviation, which reduces the working quality of the device, and to propose an automatic raw material feeding device in the production process of a composite wet strength agent.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an automatic raw material feeding device in the production process of a composite wet strength agent, including a box body and a fixing frame. The upper end of the box body is fixedly connected with the fixing frame. A knocking device and a pushing device are arranged above the box body. The outer wall of the fixing frame is fixedly connected with a feed hopper. The inner wall of the upper end of the box body is slidably connected with a feeding cylinder, and a baffle is fixedly connected to the outer wall of the feeding cylinder.

[0007] Preferably, the knocking device includes a first motor and a first outer shell. The lower end of the first outer shell is fixedly connected to the box body. The first motor is fixedly connected to the first outer shell through a bracket. An output shaft of the first motor is fixedly connected with an incomplete gear. An outer wall of the incomplete gear meshes with a rack. An upper end of the rack is fixedly connected with a striking block. A fixing rod is fixedly connected to an inner wall of the first outer shell. A spring is arranged on an outer wall of the fixing rod. Two ends of the spring are respectively fixedly connected to the first outer shell and the striking block.

[0008] Preferably, a rotating shaft of the incomplete gear is rotatably connected to the first outer shell through a bearing. An outer wall of the striking block is slidably connected to the first outer shell. An inner wall of the striking block is slidably connected to the fixing rod.

[0009] Preferably, a feeding pipe is fixedly connected to an upper end of the box body. A feeding tube is fixedly connected to a left side of the box body.

[0010] Preferably, the pushing device includes a second motor and a second outer shell. The lower end of the second outer shell is fixedly connected to the box body. The second motor is fixedly connected to the second outer shell through a bracket. An output shaft of the second motor is fixedly connected with a worm. An outer wall of the worm meshes with a worm wheel. A rotating shaft of the worm wheel is fixedly connected with a rotating rod. A convex block is fixedly connected to an outer wall of the rotating rod. The outer wall of the convex block is slidably connected to a sliding rod.

[0011] Preferably, two ends of the worm are rotatably connected to the second outer shell through bearings. A rotating shaft of the worm wheel is rotatably connected to the second outer shell through a bearing. An outer wall of the sliding rod is slidably connected to the second outer shell. A feeding cylinder is fixedly connected to a right end of the sliding rod.

[0012] For an automatic raw material feeding device during the production process of a composite wet strength agent proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the knocking device and the feeding hopper, solid reagent raw materials are added into the feeding hopper. When starting the output shaft of the first motor to rotate, the incomplete gear is driven to rotate. While the incomplete gear rotates, the rack and the striking block are driven to move to the right side, and the striking block compresses the spring. When the incomplete gear no longer meshes with the rack, under the reaction force of the spring, the rack and the striking block are pushed to move quickly and strike the feeding hopper. By continuously rotating the output shaft of the first motor, the striking block strikes the feeding hopper. The vibration generated by the impact avoids the accumulation of solid reagent raw materials at the bottom of the feeding hopper, eliminating the need for operators to manually knock, reducing the workload of operators, and improving work efficiency.

[0013] Through the cooperation of the feeding device and the feeding cylinder, starting the rotation of the output shaft of the second motor drives the worm to rotate. The rotation of the worm drives the synchronous rotation of the worm wheel and the rotating rod. The rotation of the rotating rod drives the convex block to move inside the sliding rod. While the convex block moves inside the sliding rod, it drives the sliding rod to move to the right. The sliding rod pushes the feeding cylinder to move to the right, and the baffle on the left side of the feeding cylinder moves synchronously. The baffle seals the bottom of the feed hopper. At the same time, when the feeding cylinder is connected to the feeding pipe, the solid reagent raw materials inside the feeding cylinder are put into the box through the feeding pipe, realizing quantitative feeding and improving the work efficiency.

[0027] Working principle:

[0028] Liquid reagent raw materials are added into the box body 1 through the feed pipe 8.

[0029] The knocking process of the feed hopper:

[0030] Solid reagent raw materials are added into the feed hopper 5. The external power supply of the first motor 201 is connected, and the output shaft of the first motor 201 is started to rotate, driving the rotation of the incomplete gear 203.
