A blade fixing structure for a pullulan polysaccharide hollow capsule cutting device

Abstract

This utility model discloses a blade fixing structure for a pullulan empty capsule cutting device, including a mounting shaft, one end of which is connected to the drive motor of the pullulan empty capsule cutting device. This utility model features a pressing block, a second limiting rod, a mounting shaft, and an elastic block. During installation, the cutting blade is initially positioned by passing it through the pressing block onto the mounting shaft. Then, the pressing block is pressed inward, causing the connecting seat to move. The movement of the connecting seat, via the first limiting rod, drives the second limiting rod to rotate, simultaneously causing the moving block to move. The movement of the moving block stretches the spring until the elastic block engages with the mounting shaft. For disassembly, the elastic block is pressed inward, and a certain outward pulling force is applied to the pressing block until the second limiting rod rotates to a horizontal position. Then, the cutting blade is removed. This method facilitates quick and easy disassembly and assembly of the cutting blade, saving time and effort without the need for auxiliary tools, thus improving the convenience of blade maintenance.

Description

Technical Field

[0001] This utility model relates to the field of pullulan empty capsule production technology, specifically to a blade fixing structure for a pullulan empty capsule cutting device. Background Technology

[0002] Pullulan empty capsules are empty hard capsules made with pullulan, obtained from natural raw materials through microbial fermentation, as the main ingredient, supplemented with other additives. The raw materials are all-natural plant-based and do not contain animal ingredients, which can meet the needs of special dietary cultures such as vegetarianism.

[0003] In real life, pullulan polysaccharide empty capsules are usually cut using cutting equipment during production and processing. To ensure the stability of the blades on the cutting equipment under high-speed operation, the blades are mostly fixed by bolts. When the blades are disassembled and maintained, auxiliary tools are required. The entire disassembly and assembly process is time-consuming and laborious, reducing the convenience of blade maintenance. Therefore, a blade fixing structure for pullulan polysaccharide empty capsule cutting equipment is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a blade fixing structure for a pullulan polysaccharide hollow capsule cutting device, in order to solve the problem mentioned in the background art, where blades are mostly fixed by bolt connection, and when the blade is disassembled and maintained, auxiliary tools are required, making the whole disassembly and assembly process time-consuming and laborious, thus reducing the convenience of blade maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a blade fixing structure for a pullulan polysaccharide hollow capsule cutting device, comprising:

[0007] The mounting shaft, one end of which is connected to the drive motor of the pullulan polysaccharide hollow capsule cutting device;

[0008] A fixing assembly includes a movable block, the outer wall of which is slidably disposed inside a mounting shaft. Elastic blocks are fixedly disposed at both the upper and lower ends of the outer wall of the movable block. A connecting rod is fixedly disposed on one side of the movable block, and a spring is sleeved on the outer wall of the connecting rod. A connecting seat is fixedly disposed at the other end of the connecting rod. A pressing block is fixedly disposed on one side of the connecting seat. First limiting rods are rotatably disposed at both the upper and lower ends of the connecting seat. Second limiting rods are rotatably disposed on opposite sides of the two first limiting rods. The opposite sides of the two second limiting rods are respectively rotatably disposed at the upper and lower ends of the mounting shaft.

[0009] A cutting blade, the inner wall of which is fitted onto the outer wall of the mounting shaft.

[0010] Furthermore, a limiting ring is fixedly provided on one side of the outer wall of the mounting shaft, and a first positioning rod is fixedly provided at both ends of one side of the limiting ring.

[0011] Furthermore, the outer walls of the two elastic blocks are respectively engaged and connected to the upper and lower ends of the outer wall of the mounting shaft.

[0012] Furthermore, one end of the spring is fixedly connected to one side of the movable block, and the other end of the spring is fixedly connected to one end of the inner wall of the mounting shaft.

[0013] Furthermore, the outer wall of the mounting shaft is located at the middle position between the limiting ring and the elastic block, and the bearing is connected to a protective cover.

[0014] Furthermore, a fixing groove is provided on one side of the pressing block, and two connecting blocks are rotatably provided on the inner wall of the fixing groove. A second positioning rod is fixedly provided on the opposite end of each of the two connecting blocks.

[0015] Furthermore, the two second positioning rods and the two first positioning rods are arranged in a cross shape.

[0016] This utility model has the following beneficial effects:

[0017] This invention features a push block, a second limiting rod, a mounting shaft, and an elastic block. During installation, the cutting blade is initially positioned by passing it through the push block onto the mounting shaft. Then, the push block is pressed inwards, causing the connecting seat to move. This movement of the connecting seat, via the first limiting rod, drives the second limiting rod to rotate, simultaneously moving the moving block. The moving block stretches the spring until the elastic block engages with the mounting shaft. For disassembly, the elastic block is pressed inwards, and a certain outward pulling force is applied to the push block until the second limiting rod rotates to a horizontal position. The cutting blade can then be removed. This method facilitates quick and easy disassembly and assembly of the cutting blade, saving time and effort without the need for auxiliary tools, thus improving the convenience of blade maintenance.

[0018] Based on the aforementioned beneficial effects, by providing a connecting block and a second positioning rod, after the cutting blade is initially positioned on the mounting shaft, the two connecting blocks are rotated in opposite directions to a vertical position. When the cutting blade is fixed by pressing the block, the connecting block will drive the second positioning rod to move together, so that the second positioning rod can position the cutting blade a second time. This can further position the cutting blade, thereby improving the stability of the blade under high-speed operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this utility model is a blade fixing structure for a pullulan polysaccharide hollow capsule cutting device, comprising:

[0030] Mounting shaft 1, one end of which is connected to the drive motor of the pullulan polysaccharide hollow capsule cutting device;

[0031] Mounting shaft 1 is used to transmit the driving force provided by the drive motor;

[0032] The fixing component 2 includes a movable block 201. The outer wall of the movable block 201 is slidably disposed inside the mounting shaft 1. Elastic blocks 202 are fixedly disposed at both the upper and lower ends of the outer wall of the movable block 201. A connecting rod 203 is fixedly disposed on one side of the movable block 201. A spring 204 is sleeved on the outer wall of the connecting rod 203. A connecting seat 205 is fixedly disposed at the other end of the connecting rod 203. A pressing block 206 is fixedly disposed on one side of the connecting seat 205. A first limiting rod 207 is rotatably disposed at both the upper and lower ends of the connecting seat 205. A second limiting rod 208 is rotatably disposed on the opposite side of the two first limiting rods 207. The opposite sides of the two second limiting rods 208 are respectively rotatably disposed at the upper and lower ends of the mounting shaft 1.

[0033] The outer wall of the connecting rod 203 passes through the other end of the mounting shaft 1 and is slidably connected to the other end of the mounting shaft 1. The upper and lower second limiting rods 208 rotate in opposite directions. When the second limiting rod 208 rotates to the horizontal position, one side of it contacts the side of the blade, which can be used to limit and fix the blade. The outer diameter of the button 206 is adapted to the outer diameter of the mounting shaft 1. The distance between the opposite ends of the upper and lower first limiting rods 207 is smaller than the outer diameter of the button 206.

[0034] Cutting blade 3, the inner wall of cutting blade 3 is fitted onto the outer wall of mounting shaft 1;

[0035] Cutting blade 3 is used to cut pullulan polysaccharide empty capsules;

[0036] A limiting ring 5 is fixedly provided on one side of the outer wall of the mounting shaft 1, and a first positioning rod 6 is fixedly provided at both ends of one side of the limiting ring 5.

[0037] The limiting ring 5 is used to limit the initial fixed position of the cutting blade 3, and the first positioning rod 6 is used to position the cutting blade 3 so that it rotates together with the mounting shaft 1;

[0038] The outer walls of the two elastic blocks 202 are respectively engaged and connected to the upper and lower ends of the outer wall of the mounting shaft 1;

[0039] Both the upper and lower ends of the outer wall of the mounting shaft 1 are provided with locking holes that are compatible with the elastic block 202;

[0040] One end of the spring 204 is fixedly connected to one side of the moving block 201, and the other end of the spring 204 is fixedly connected to one end of the inner wall of the mounting shaft 1.

[0041] When the spring 204 is in its normal state, the first limiting rod 207 and the second limiting rod 208 are located in the same vertical plane;

[0042] The outer wall of the mounting shaft 1 is located at the middle position between the limiting ring 5 and the elastic block 202, and the bearing is connected to the protective cover 4;

[0043] Working principle: When installing the cutting blade 3, move the mounting hole in the middle of the cutting blade 3 through the push block 206 to the mounting shaft 1, and position one side of the cutting blade 3 against the limiting ring 5. Then press the push block 206 inward. The movement of the push block 206 drives the connecting rod 203 to move through the connecting seat 205. The movement of the connecting rod 203 drives the moving block 201 to move, thereby stretching the spring 204. At the same time, the movement of the connecting seat 205 drives the second limiting rod 208 to rotate through the first limiting rod 207 until the elastic block 202 is engaged with the outer wall of the mounting shaft 1. At this time, the second limiting rod 208 contacts one side of the cutting blade 3. When removing the cutting blade 3, press the elastic block 202 inward. Under the elastic action of the spring 204, the moving block 201 moves in the opposite direction, thereby driving the connecting seat 205 to move outward. Then apply a certain outward pulling force to the push block 206 until the second limiting rod 208 rotates to the horizontal position. Then remove the cutting blade 3 outward.

[0044] This step allows for quick and easy disassembly and assembly of the cutting blade 3. The entire disassembly and assembly process is convenient and labor-saving, requiring no auxiliary tools and improving the ease of blade maintenance.

[0045] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0046] A fixing groove 9 is provided on one side of the pressing block 206. Two connecting blocks 7 are rotatably provided on the inner wall of the fixing groove 9. A second positioning rod 8 is fixedly provided on the opposite end of the two connecting blocks 7.

[0047] The second positioning rod 8 is an elastic rod;

[0048] The two second positioning rods 8 and the two first positioning rods 6 are arranged in a cross shape;

[0049] The cutting blade 3 has a first positioning hole and a second positioning hole respectively provided at corresponding positions to match the first positioning rod 6 and the second positioning rod 8;

[0050] Working principle: Before the cutting blade 3 passes through the push block 206, press the two second positioning rods 8 in opposite directions. After the cutting blade 3 passes through the second positioning rods 8 and is positioned and attached to the limiting ring 5, release the second positioning rods 8 and rotate the two connecting blocks 7 in opposite directions to the vertical position. When the push block 206 is pressed inward, it will drive the connecting block 7 to move together. After the cutting blade 3 is installed and fixed, the second positioning rod 8 on one side of the connecting block 7 is engaged with the cutting blade 3.

[0051] This step allows for further positioning of the cutting blade 3, thereby improving the stability of the blade under high-speed operation.
