Description

Technical Field

[0001] This utility model relates to the field of hemostatic powder production technology, and in particular to a stirring and mixing mechanism. Background Technology

[0002] Absorbable hemostatic powder is suitable for use in various surgical procedures when ligation or other conventional control methods are ineffective or impossible, as an auxiliary product to control capillary bleeding. Absorbable compound polysaccharide hemostatic powder is physically mixed from cross-linked potato starch and sodium carboxymethyl starch treated with ethanol in a ratio of 9:1. Both components are plant starch polysaccharides.

[0003] In the process of mixing raw materials for hemostatic powder production, a mixing mechanism is required. However, after use, the powdery raw materials tend to stick to the inside of the conventional mixing mechanism, and the internal structure of the mechanism is not easy to clean, which affects subsequent production. Utility Model Content

[0004] The purpose of this invention is to provide a mixing mechanism that solves the problem that after conventional mixing mechanisms are used, powdery raw materials will adhere to the inside of the mechanism and the internal structure of the mechanism is not easy to clean, which will affect subsequent production.

[0005] To achieve the above objectives, this utility model provides a mixing mechanism, including a mixing tank, a discharge hopper, a mixer, and an anti-clogging device. The mixer is installed inside the mixing tank, the discharge hopper is fixedly installed inside the mixing tank, and the anti-clogging device is installed on the mixing tank. It also includes a cleaning device, which comprises a mounting plate, a guide block, a cleaning ring, a connecting rod, an air supply assembly, and a lifting assembly. The mounting plate is fixedly installed on the outside of the mixing tank, and a guide groove is provided on the inside of the mixing tank. The guide block is slidably installed inside the mixing tank and located within the guide groove. The cleaning ring is fixedly installed on the guide block and has an air guide hole. The connecting rod is fixedly installed on the cleaning ring, and the lifting assembly drives the connecting rod to rise and fall. The air supply assembly is installed on the mixing tank.

[0006] The lifting assembly includes a lifting plate and a cylinder, with the cylinder fixedly mounted on the mounting plate; the lifting plate is fixedly mounted on the output end of the cylinder and fixedly connected to the connecting rod.

[0007] The air supply assembly includes an air pump and an air inlet pipe. The air pump is fixedly installed on the outside of the mixing tank. One end of the air inlet pipe is connected to the air outlet of the air pump, and the other end of the air inlet pipe is connected to the cleaning ring.

[0008] The anti-clogging device includes a discharge pipe, a screw rod, a motor, and a support assembly. The discharge pipe is connected to the discharge hopper and passes through the mixing tank, extending to the outside of the mixing tank. The motor is mounted on the mixing tank via the support assembly. The screw rod is fixedly mounted on the output shaft of the motor and extends into the discharge pipe.

[0009] The support assembly includes a support plate and a support rod, with the support rod fixedly mounted on the mixing tank; the support plate is fixedly mounted on the support rod, and the motor is fixedly mounted on the support plate.

[0010] This utility model discloses a mixing mechanism. In use, hemostatic powder is poured into a mixing tank, and then stirred by a mixer. After stirring, the powder is discharged through an anti-clogging device. When cleaning is required, an air pump is activated, which introduces high-pressure gas into a cleaning ring through the air inlet pipe. The cleaning ring then ejects high-pressure gas through the air guide hole. Simultaneously, a cylinder is activated, causing a lifting plate to move downwards. The movement of the lifting plate, via a connecting rod, causes the cleaning ring to move downwards, allowing the high-pressure gas to blow away any remaining material residue from the mixer and the inner wall of the mixing tank, which is then discharged through the discharge hopper. This makes the interior of the mechanism easier to clean. Attached Figure Description

Detailed Implementation

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] The first embodiment of this application is as follows:

[0018] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of a stirring and mixing mechanism according to the first embodiment of this utility model. Figure 2 This is a schematic diagram showing the connection between the mixing tank and the discharge hopper in the first embodiment of this utility model.

[0019] This utility model provides a mixing mechanism, including a mixing tank 101, a discharge hopper 102, a mixer 103, and an anti-clogging device. It also includes a cleaning device comprising a mounting plate 104, a guide block 105, a cleaning ring 106, a connecting rod 107, an air supply assembly, and a lifting assembly. The lifting assembly includes a lifting plate 110 and a cylinder 111, and the air supply assembly includes an air pump 112 and an air inlet pipe 113. This solution addresses the problem that conventional mixing mechanisms, after use, suffer from powdery raw materials adhering to the interior, making cleaning difficult and affecting subsequent production. This solution can be used in mixing hemostatic powder raw materials and also to solve the problem of anti-clogging at the mixing tank discharge point.

[0020] In this embodiment, by vertically driving the cleaning ring 106, the cleaning ring 106 blows away the raw material residue on the inner wall of the mixer 103 and the mixing tank 101 with the high-pressure gas, and discharges it through the discharge hopper 102, thereby making the inside of the mechanism easier to clean.

[0021] The mounting plate 104 is fixedly installed on the outside of the mixing tank 101. A guide groove 108 is provided on the inner side of the mixing tank 101. A guide block 105 is slidably installed inside the mixing tank 101 and located within the guide groove 108. A cleaning ring 106 is fixedly installed on the guide block 105. An air guide hole 109 is provided on the cleaning ring 106. A connecting rod 107 is fixedly installed on the cleaning ring 106. The lifting assembly drives the connecting rod 107 to rise and fall. An air supply assembly is installed on the mixing tank 101. The mixing tank 101 has an outer square and inner round structure. The discharge hopper 102 is located at the bottom of the mixer 103. The mixer 103 consists of a stirring roller, a stirring rod, and a drive source. There are two sets of mounting plates 104, symmetrically arranged on both sides of the mixing tank 101. Each set of mounting plates 104 is equipped with one set of the lifting assembly. The cleaning ring 106 has a notch on one side near the mixer 103. The cleaning ring 106 has a hollow structure. The air guide hole 109 penetrates the inner and outer rings of the cleaning ring 106 and is distributed in a ring on the cleaning ring 106. There are three sets of guide blocks 105, which are distributed in a ring on the outer ring of the cleaning ring 106. There are two sets of connecting rods 107, which are symmetrically arranged on both sides of the upper end of the cleaning ring 106. The air supply component can inject high-pressure gas into the cleaning ring 106. The lifting component drives the connecting rods 107, so that the connecting rods 107 drive the cleaning ring 106 to move downward. The cleaning ring 106 blows off the raw material residue on the inner wall of the mixer 103 and the mixing tank 101 through the high-pressure gas, and discharges it through the discharge hopper 102, thereby making the inside of the mechanism easier to clean.

[0022] Secondly, the cylinder 111 is fixedly mounted on the mounting plate 104; the lifting plate 110 is fixedly mounted on the output end of the cylinder 111 and fixedly connected to the connecting rod 107. The lifting plate 110 is welded to the output end of the cylinder 111. The cylinder 111 is fixed to the mounting plate 104 by screws. The cylinder 111 drives the lifting plate 110 to move vertically through the movement of its output end. The movement of the lifting plate 110 drives the connecting rod 107 to rise and fall.

[0023] Furthermore, the air pump 112 is fixedly installed on the outside of the mixing tank 101; one end of the air inlet pipe 113 is connected to the air outlet of the air pump 112, and the other end of the air inlet pipe 113 is connected to the cleaning ring 106. The air pump 112 is fixed to the outside of the mixing tank 101 by screws. The air inlet pipe 113 is a corrugated pipe that can extend and retract as the cleaning ring 106 moves. Through the drive of the air pump 112 and the air guiding effect of the air inlet pipe 113, the high-pressure gas generated inside the air pump 112 can enter the cleaning ring 106.

[0024] In this embodiment, during use, the hemostatic powder raw material is poured into the mixing tank 101, and then stirred by the mixer 103. After stirring, the raw material is discharged through the anti-clogging device. When cleaning is required, the air pump 112 is started, so that the air pump 112 introduces high-pressure gas into the cleaning ring 106 through the air inlet pipe 113. The cleaning ring 106 sprays high-pressure gas through the air guide hole 109. At the same time, the cylinder 111 is started, and the cylinder 111 drives the lifting plate 110 to move downward. The movement of the lifting plate 110 drives the cleaning ring 106 to move downward through the connecting rod 107, so that the cleaning ring 106 blows away the raw material residue on the mixer 103 and the inner wall of the mixing tank 101 through the blown high-pressure gas, and discharges it through the discharge hopper 102, thereby making the inside of the mechanism easier to clean.

[0025] The second embodiment of this application is as follows:

[0026] Please see Figure 3 ,in Figure 3 This is a schematic diagram of the overall structure of a mixing mechanism according to the second embodiment of the present invention. Based on the first embodiment, the mixing mechanism of this embodiment further includes an anti-blocking device. The anti-blocking device includes a discharge pipe 201, a screw rod 202, a motor 203, and a support assembly. The support assembly includes a support plate 204 and a support rod 205.

[0027] In this embodiment, the rotation of the screw rod 202 allows the hemostatic powder raw material to be discharged from the hemostatic tube, thereby preventing the hemostatic powder raw material from becoming blocked in the discharge pipe 201.

[0028] The discharge pipe 201 is connected to the discharge hopper 102, and also passes through the mixing tank 101, extending to the outside of the mixing tank 101. The motor 203 is mounted on the mixing tank 101 via the support assembly. The screw rod 202 is fixedly mounted on the output shaft of the motor 203 and extends into the discharge pipe 201. The discharge pipe 201 is L-shaped, and a control valve is provided at one end of the discharge pipe 201 near the discharge hopper 102. The outer surface of the swivel rod 202 is provided with spiral blades. The spiral rod 202 is welded to the output shaft of the motor 203. The support assembly can provide support for the motor 203. During discharge, the hemostatic powder raw material enters the discharge pipe 201 through the discharge hopper 102. At the same time, the motor 203 drives the spiral rod 202 to rotate. The rotation of the spiral rod 202 drives the hemostatic powder raw material to be discharged from the discharge pipe 201, thereby avoiding blockage of the hemostatic powder raw material in the discharge pipe 201.

[0029] Secondly, the support rod 205 is fixedly installed on the mixing tank 101; the support plate 204 is fixedly installed on the support rod 205, and the motor 203 is fixedly installed on the support plate 204. There are three sets of support rods 205, which are distributed in a ring on the support plate 204. The support rods 205 are welded to the outside of the mixing tank 101. The support plate 204 has a disc structure. The motor 203 is fixed to the support plate 204 by bolts. Thus, through the cooperation of the support plate 204 and the support rod 205, the motor 203 can be supported for installation.
