Description

Technical Field

[0001] This utility model relates to the technical field of spiral mixing equipment, specifically to a novel spiral blade connection structure for a mixer. Background Technology

[0002] A granulator is a molding machine that can shape materials into specific shapes. When a granulator is working, a mixing mechanism is used to mix the poured materials to make them evenly mixed, thus obtaining a granulated mixture.

[0003] In related technologies, twin-screw mixers are usually used to achieve higher material mixing quality. However, after prolonged use, the spiral blades of the twin-screw mixer can become damaged, affecting the material mixing effect. Consequently, it is necessary to disassemble, repair, and replace the spiral blades on the spiral mixer.

[0004] Currently, most twin-spiral mixers have blades that are integrated with the rotating roller. When the blades are damaged, it is inconvenient to replace them, which makes the device unable to meet more usage needs and results in excessive maintenance costs. To solve the above problems, a new type of spiral blade connection structure for mixers is proposed. Utility Model Content

[0005] In view of this, the present invention provides a novel connecting structure for the spiral blades of a mixer. The present invention separates the first arc plate from the second arc plate by removing the first bolt, thereby separating the positioning ring from the double rotating shaft. Then, the second bolt is removed to separate the mounting groove from the spiral blade, thereby allowing the spiral blade to be inspected or replaced, thus reducing the maintenance cost of the equipment.

[0006] To solve the above-mentioned technical problems, this utility model provides a novel spiral blade connection structure for a mixer, including a double rotating shaft disposed inside the mixing box of a double spiral mixer, a drive motor disposed at the front end of the double rotating shaft, a worm gear assembly disposed at the end of the double rotating shaft, and a plurality of spiral assemblies disposed on the surface of the double rotating shaft. The spiral assemblies are arranged alternately in the longitudinal direction and alternately in the transverse direction. Each spiral assembly includes a positioning ring that is detachably installed on the surface of the double rotating shaft. A connecting block is symmetrically disposed on the surface of each positioning ring, and an arc-shaped blade assembly is disposed on the side of each connecting block away from the positioning ring.

[0007] Each positioning ring consists of a first arc-shaped plate and a second arc-shaped plate joined together. A positioning block is provided at both ends of the first arc-shaped plate and the second arc-shaped plate. The positioning block is used to make the ends of the first arc-shaped plate and the second arc-shaped plate fit together. A first threaded hole is provided through the positioning block. The first threaded hole is used to install a first bolt. Each first threaded hole is provided with a first bolt. The first bolt is used to fix the connection between the first arc-shaped plate and the second arc-shaped plate.

[0008] Each arc-shaped blade assembly includes a mounting groove fixed to the connecting block. The mounting groove is used to connect the connecting block and the spiral blade. The mounting groove is set vertically. The upper half of each mounting groove away from the groove opening is provided with a spiral blade. The spiral blade is used to convey the material in the twin-spiral mixer. The spiral blade is fan-shaped.

[0009] Each mounting slot is provided with a pair of second threaded holes for installing second bolts. The second threaded holes pass through the mounting slot and the spiral blade, and the second bolts are provided in the second threaded holes for connecting and fixing the mounting slot and the spiral blade.

[0010] The dual rotating shafts include a main rotating shaft and a driven rotating shaft. The main rotating shaft is used to connect with the drive motor to drive the driven rotating shaft to rotate. A first bearing housing is provided at one end of the main rotating shaft to fix the main rotating shaft. A second bearing housing is provided at one end of the driven rotating shaft to fix the driven rotating shaft. The first bearing housing is connected to the drive motor.

[0011] The worm gear assembly includes a main worm gear set and a driven worm gear set. The main worm gear set drives the driven worm gear set to rotate, thereby rotating the driven rotating shaft. The main worm gear set is mechanically connected to the main rotating shaft, and the driven worm gear set is mechanically connected to the driven rotating shaft. The worm gears on the main worm gear set mesh with the worm gears on the driven worm gear set.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. By removing the first bolt, the first arc plate is separated from the second arc plate, thereby separating the positioning ring from the double rotating shaft. Then, the second bolt is removed to separate the mounting groove from the spiral blade, so that the spiral blade can be inspected or replaced, thereby reducing the maintenance cost of the equipment.

[0014] 2. When the drive motor is started, the main rotating shaft rotates, which in turn rotates the main worm gear set fixed at the end of the main rotating shaft. This causes the driven worm gear set, which meshes with the main worm gear set, to rotate, thereby causing the driven rotating shaft connected to the driven worm gear set to rotate. This enables the two rotating shafts to rotate synchronously. The helical assembly is evenly installed on the surfaces of the main rotating shaft and the driven rotating shaft, thereby driving the helical assembly to rotate.

[0015] 3. By staggering the spiral components, the arc blades on the spiral components are also staggered, thus preventing the spiral blades on the arc blades from being staggered, which prevents the spiral blades from colliding while conveying materials. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figure 1-6As shown: This embodiment provides a novel spiral blade connection structure for a mixer, including a double-spiral mixer 100 with a double rotating shaft 101 disposed inside the mixing chamber. The double rotating shaft 101 includes a main rotating shaft 400 and a driven rotating shaft 401. A drive motor 102 is disposed at the front end of the double rotating shaft 101, which drives the main rotating shaft 400 on the double rotating shaft 101. This causes the main worm gear set 404 fixed on the main rotating shaft 400 to drive the driven worm gear set 405 to rotate, thereby driving the driven rotating shaft 401 to rotate. A worm gear assembly 103 is disposed at the end of the double rotating shaft 101, which includes the main worm gear set 404 and the driven worm gear set 405. Multiple spiral assemblies 200 are disposed on the surface of the double rotating shaft 101. The spiral assemblies 200 are arranged alternately in the longitudinal direction and in the transverse direction. The spiral components 200 are staggered and fixed to the surfaces of the main rotating shaft 400 and the secondary rotating shaft 401 on the dual rotating shaft 101, thereby preventing the spiral blades 302 on the two identical spiral components 200 from colliding. Each spiral component 200 includes a positioning ring 201 that is detachably mounted to the surface of the dual rotating shaft 101. A connecting block 202 is symmetrically arranged on the surface of each positioning ring 201. A connecting block 202 is welded to the surfaces of the first arc plate 203 and the second arc plate 204 on the positioning ring 201, respectively. An arc blade group 300 is arranged on the side of each connecting block 202 away from the positioning ring 201. The first arc plate 203 and the second arc plate 204 on the positioning ring 201 can be fixed to the surface of the dual rotating shaft 101 by welding the positioning block 207 between them.

[0025] When it is necessary to disassemble and replace the spiral blade 302 during use, first disconnect the power and stop the machine. Then, remove the first bolt 206 to separate the first arc plate 203 from the second arc plate 204, thereby separating the positioning ring 201 from the double rotating shaft 101. Then, remove the second bolt 304 to separate the mounting groove 301 from the spiral blade 302, so that the spiral blade 302 can be inspected or replaced, thereby reducing the maintenance cost of the equipment.

[0026] This embodiment provides a novel connection structure for the spiral blade 302 of a mixer.

[0027] like Figure 1 , 2As shown in Figures 4 and 5: Each positioning ring 201 comprises a first arc-shaped plate 203 and a second arc-shaped plate 204 joined together. A positioning block 207 is provided at both ends of the first arc-shaped plate 203 and the second arc-shaped plate 204. A positioning block 207 is welded to both the left and right ends of the first arc-shaped plate 203, and a positioning block 207 is welded to both the left and right ends of the second arc-shaped plate 204. The positioning blocks 207 on the first arc-shaped plate 203 and the second arc-shaped plate 204 correspond and fit together, thereby forming a circle around the first arc-shaped plate 203 and the second arc-shaped plate 204 and fixing it to the rotating shaft surface of the double rotating shaft 101. The positioning blocks 207 are used for... The ends of the first arc plate 203 and the second arc plate 204 are fitted together. A first threaded hole 205 is provided through the positioning block 207. The first threaded hole 205 passes through the positioning block 207 on the first arc plate 203 and the positioning block 207 on the second arc plate 204. The first threaded hole 205 is used to install the first bolt 206. Each first threaded hole 205 is provided with a first bolt 206. The first bolt 206 is threadedly engaged with the first threaded hole 205. The first bolt 206 is used to fix the connection between the first arc plate 203 and the second arc plate 204. After the first bolt 206 passes through the first threaded hole 205, it is fixed with a nut and a washer.

[0028] The effect is that the first arc plate 203 and the second arc plate 204 form a circle and are fixed on the rotating surface of the double rotating shaft 101, thereby enabling the positioning ring 201 to be detachably connected to the surface of the double rotating shaft 101.

[0029] like Figure 1 , 2 As shown in Figures 3, 4, and 5: Each arc-shaped blade assembly 300 includes a mounting groove 301 fixed to the connecting block 202. The mounting groove 301 is square and has an internal slot for installing a second bolt 304. The mounting groove 301 is used to connect the connecting block 202 and the spiral blade 302. The mounting groove 301 is vertically arranged and welded to the connecting block 202. A spiral blade 302 is provided on the upper half of each mounting groove 301 away from the slot opening. The spiral blade 302 is used for... The material in the mixing box of the double helix mixer 100 is conveyed. The helical blades 302 are fan-shaped. Each mounting slot 301 is provided with a pair of second threaded holes 303. The second threaded holes 303 are used to install second bolts 304. The second threaded holes 303 pass through the mounting slots 301 and the helical blades 302. The second threaded holes 303 pass through the lower part of the helical blades 302. The second threaded holes 303 are provided with second bolts 304. The second bolts 304 are used to connect and fix the mounting slots 301 and the helical blades 302.

[0030] The effect is as follows: the second threaded hole 303 on the mounting groove 301 corresponds to the second threaded hole 303 on the spiral blade 302, so that the second bolt 304 is installed into the second threaded hole 303, and then fixed by using a nut and a washer, so that the spiral blade 302 and the mounting groove 301 are detachably connected.

[0031] like Figure 1 , 3 As shown in Figure 6, the dual rotating shaft 101 includes a main rotating shaft 400 and a driven rotating shaft 401. The main rotating shaft 400 is used to connect with the drive motor 102 to drive the driven rotating shaft 401 to rotate. A first bearing seat 402 is provided at one end of the main rotating shaft 400. One end of the first bearing seat 402 is mechanically sealed to the main rotating shaft 400. The other end of the first bearing seat 402 can be mechanically sealed to the shaft on the drive motor 102 through a coupling. The first bearing seat 402 is used to fix the main rotating shaft 400. A second bearing seat 403 is provided at one end of the driven rotating shaft 401. The second bearing seat 403 is used to fix the driven rotating shaft 401 to prevent the driven shaft from falling off. The first bearing seat 402 is connected to the drive motor 102.

[0032] Its effect is as follows: the main rotating shaft 400 is used to connect with the drive motor 102 to drive the driven rotating shaft 401 to rotate, and the second bearing seat 403 is used to fix the driven rotating shaft 401 to prevent the driven rotating shaft from falling off.

[0033] like Figure 1 , 3 As shown in Figure 6, the worm gear assembly 103 includes a main worm gear set 404 and a driven worm gear set 405. The main worm gear set 404 drives the driven worm gear set 405 to rotate, thereby causing the driven rotating shaft 401 to rotate. The main worm gear set 404 is mechanically connected to the main rotating shaft 400, and the driven worm gear set 405 is mechanically connected to the driven rotating shaft 401. The main worm gear set 404 and the main rotating shaft 400 can be connected by a key, and the driven worm gear set 405 and the driven rotating shaft 401 can be connected by a key. The worm gears on the main worm gear set 404 mesh with the worm gears on the driven worm gear set 405.

[0034] Its effect is as follows: the main worm gear set 404 drives the driven worm gear set 405 to rotate, thereby causing the driven rotating shaft 401 to rotate, thereby causing the main rotating shaft 400 and the spiral assembly 200 fixed on the surface of the driven rotating shaft 401 to rotate.

[0035] Working principle: When the drive motor 102 is started, the main rotating shaft 400 rotates, thereby rotating the main worm gear set 404 fixed at the end of the main rotating shaft 400. This, in turn, causes the driven worm gear set 405, which meshes with the main worm gear set 404, to rotate, thus rotating the driven rotating shaft 401 connected to the driven worm gear set 405. This causes the two rotating shafts 101 to rotate synchronously. The spiral assembly 200 is evenly installed on the surfaces of the main rotating shaft 400 and the driven rotating shaft 401, thereby driving the spiral assembly 200 to rotate. Through the staggered arrangement of the spiral assemblies 200, the arc on the spiral assembly 200... The shaped blade group 300 is also staggered, thus preventing the spiral blades 302 on the arc blade group 300 from being staggered. While conveying materials, it also prevents the spiral blades 302 from colliding. When it is necessary to disassemble and replace the spiral blades 302, first disconnect the power and stop the machine. Then, remove the first bolt 206 to separate the first arc plate 203 from the second arc plate 204, thereby separating the positioning ring 201 from the double rotating shaft 101. Then, remove the second bolt 304 to separate the mounting groove 301 from the spiral blades 302, thereby allowing the spiral blades 302 to be inspected or replaced, thus reducing the maintenance cost of the equipment.

[0036] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
