Description

Technical Field

[0001] This invention relates to the field of solid mixing machine technology, and specifically to a gradient closed homogenizing mixing machine. Background Technology

[0002] In the cable manufacturing industry, the standards for mixing materials exceed those in the general plastics industry. It is necessary to ensure that plastic granules and additives are uniformly mixed and dispersed, and to control shear strength and temperature during mixing. If the mixing environment is not well controlled, it may cause material degradation, softening or agglomeration, affecting the performance of the cable insulation layer. Currently, the most commonly used insulation materials for cables are CPVC and MPP. The mixing of the two is carried out in the order of raw material premixing, solid premixing, melt mixing, granulation and cooling, so as to become raw materials that can be directly extruded for insulation layer.

[0003] In existing technologies, CPVC materials require strict temperature control during solid premixing. The first-stage mixing of CPVC resin and additives relies on material self-friction for heating, and external heating is not permitted. This necessitates stirring the CPVC resin particles during mixing, creating a shear effect and causing temperature rise. The second-stage mixing requires cold mixing, which necessitates cooling the CPVC material while maintaining zero shear. Existing processing equipment lacks the ability to cool CPVC materials with hot mixing devices and the shearing function of cold mixing devices, necessitating transfer between equipment between the two stages of processing.

[0004] During transfer, the high temperature of CPVC material after hot mixing and the slow transfer speed, or the presence of residue in the equipment, can lead to decomposition of the CPVC material due to prolonged high-temperature processing. Furthermore, the loose, powdery material after hot mixing may clump together during transport, and these clumps cannot be broken up during cold mixing, making the extruded insulation layer brittle. Therefore, transferring CPVC material between equipment during the two-stage solid-state mixing process can cause material deformation, thus affecting the performance of the cable insulation layer. Consequently, a mixer capable of performing both stages of mixing separately is needed to reduce the transfer of CPVC material between equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a gradient closed homogenizing mixer, which solves the technical problem in related technologies that mixers are difficult to carry out two stages of mixing, namely hot mixing and cold mixing, and require mixing raw material transfer equipment.

[0006] A gradient-sealed homogenizing mixer includes a base and a transmission rod. The base can drive the transmission rod to rotate. It also includes an X-shaped fastener, an adjustable shearing mechanism, and a transmission assembly. The X-shaped fastener is mounted on the transmission rod, with a motor and a mixing chamber connected to its two sides respectively. The mixing chamber and the motor are axially parallel. The mixing chamber is inclined relative to the transmission rod. A cooling water jacket is fitted onto the mixing chamber. The adjustable shearing mechanism is located inside the mixing chamber and is rotatably connected within it. The adjustable shearing mechanism contains... The spiral stirring blade is capable of stretching and compressing within the mixing hopper. When the spiral stirring blade stretches and fills the entire interior of the mixing hopper, it takes on a spiral shape. The spiral stirring blade can also be compressed at one end of the mixing hopper into a disc shape. One end of the mixing hopper is configured as a transmission assembly, which is connected to the output end of the motor. The output end of the motor can drive the spiral stirring blade to rotate within the mixing hopper. The transmission rod can drive both the mixing hopper and the motor to rotate. Existing CPVC materials are mostly mixed in the cold mixing stage using V-type mixers or similar methods by shaking the mixing bin. This method of mixing by shaking the mixing bin can mix the raw materials without shearing them. In this application, the mixing bin is tilted to the side of the transmission rod, so that when the transmission rod drives the mixing bin to rotate, it can cause the raw materials in the mixing bin to move in three dimensions, maintaining a better mixing effect. At the same time, the spiral stirring blades are elastically stretchable and compressible, so that during the second-stage mixing, the spiral stirring blades are compressed and do not participate in the mixing, avoiding the spiral stirring blades from participating in the mixing during the cold mixing stage. This allows for two-stage mixing with different gradients without changing the equipment.

[0007] The mixing hopper is connected to the X-shaped fastener at its center. When raw materials are added to the mixing hopper, the weight of the motor and the mixing hopper connected to both sides of the X-shaped fastener remains balanced. In this balanced state, the motor and the mixing hopper are driven to rotate, which can prevent the transmission rod from bending due to uneven force during rotation.

[0008] The adjustable shearing mechanism further includes a mixing rod that slides through the mixing chamber at one end away from the transmission assembly. The end of the mixing rod extending into the mixing chamber is detachably connected to the transmission assembly. The end of the spiral stirring blade near the transmission assembly is fixedly connected to the mixing rod, and the end of the spiral stirring blade away from the transmission assembly is slidably connected to the mixing rod and circumferentially fixed.

[0009] When the mixing rod extends into the mixing hopper and engages with the transmission assembly, the two ends of the spiral stirring blades are respectively close to the two ends of the mixing hopper. When the transmission assembly drives the mixing rod to rotate, the spiral stirring blades can stir the raw materials in the mixing hopper. The transmission assembly includes a docking seat, a docking shaft, and a linkage component. The docking seat is fixedly connected to the mixing hopper, and the docking shaft is rotatably connected to the docking seat. The docking shaft can engage with the end of the mixing rod that extends into the mixing hopper. The linkage component provides a transmission connection between the docking shaft and the output end of the motor.

[0010] The cooling water jacket is connected to an inlet pipe and a drain pipe. The transmission rod is hollow, and both the inlet pipe and the drain pipe pass through the transmission rod to connect with external heat exchange equipment. By inserting water pipes inside the transmission rod, it is possible to prevent the water pipes from tangling when the transmission rod rotates.

[0011] The mixing hopper is equipped with a material changing port, which is located at the end of the mixing hopper away from the drive rod. As the drive rod rotates, the material changing port can face upwards or downwards. Because the mixing hopper can rotate, feeding and discharging can be completed through a single material changing port.

[0012] The spiral stirring blade is composed of multiple spiral elastic metal strips, which are rotatably connected at staggered positions. When the spiral stirring blade is stretched open, the metal strips rotate and bend, surrounding the mixing rod.

[0013] The mixing rod is provided with a clamping groove, and the mixing bin is provided with a clamping component at one end away from the transmission component. The clamping component can be engaged with the clamping groove. After the clamping component is engaged with the clamping groove, the clamping groove and the clamping component are rotatably connected. The mixing rod and the mixing bin are axially fixed. A docking groove is fixedly connected to the mixing bin. A clamping ring is slidably engaged with the docking groove. The clamping ring can be engaged with the clamping groove.

[0014] The significant technical effects of the embodiments of the present invention are as follows: 1. This invention uses X-type fasteners to tilt the mixing bin to the side of the transmission rod. The motor, as the drive device of the adjustable shearing mechanism and the balancing device of the mixing bin, is installed on the X-type fasteners. The raw materials can be stirred and mixed in the mixing bin. Then, the transmission rod drives the mixing bin to rotate to achieve two-stage mixing. The X-type fasteners realize two mixing methods of the raw materials in the mixing bin, eliminating the need to move the raw materials between two mixing devices and avoiding problems during movement. 2. This invention, by setting up a spiral stirring blade, can drive the raw materials in the mixing bin to stir. The spiral stirring blade formed by the spiral twisting of the elastic metal sheet itself is elastic and can be stretched and compressed. After stretching, it can form a spiral blade similar to the internal structure of a traditional mixer for hot mixing. When the spiral stirring blade is compressed into a disc shape, the raw materials can be cold mixed by the rotation of the mixing bin. By changing the internal structure of the mixing bin, two gradient mixing processes can be formed, avoiding possible damage to the raw materials when transferring them to other equipment.

[0025] Example 1 This invention illustrates a gradient-sealed homogenizing mixer according to one embodiment, including a base 1 and a transmission rod 2. The base 1 can drive the transmission rod 2 to rotate. It also includes an X-type fastener 3, an adjustable shearing mechanism, and a transmission assembly. Please refer to [link to relevant documentation]. Figures 1-3 An X-type fastener 3 is mounted on the transmission rod 2. A motor 4 and a mixing chamber 101 are connected to both sides of the X-type fastener 3, respectively. The mixing chamber 101 and the motor 4 are axially parallel. The mixing chamber 101 is inclined relative to the transmission rod 2. A cold water jacket 102 is fitted onto the mixing chamber 101. An adjustable shearing mechanism is located inside the mixing chamber 101 and is rotatably connected within it. Please refer to [link / reference]. Figure 4 The adjustable shearing mechanism is equipped with a spiral stirring blade 103. In this embodiment, the spiral stirring blade 103 is made of an elastic material, which can be stretched and compressed in the mixing chamber 101. When the spiral stirring blade 103 is stretched and fills the entire interior of the mixing chamber 101, the spiral stirring blade 103 is spiral-shaped. The spiral stirring blade 103 can be compressed at one end in the mixing chamber 101 and compressed into a disc shape. One end of the mixing chamber 101 is set as a transmission component, which is connected to the output end of the motor 4. The output end of the motor 4 can drive the spiral stirring blade 103 to rotate in the mixing chamber 101. The transmission rod 2 can drive the mixing chamber 101 and the motor 4 to rotate. Existing CPVC materials are cold-processed. The mixing stage is mostly carried out using V-type mixers by shaking the mixing bin 101. Shaking the mixing bin 101 can mix the raw materials without shearing them. In this application, the mixing bin 101 is tilted to the side of the transmission rod 2, so that when the transmission rod 2 drives the mixing bin 101 to rotate, it can drive the raw materials in the mixing bin 101 to move in three dimensions, maintaining a good mixing effect. At the same time, the spiral stirring blade 103 is elastically stretchable and compressible, so that during the second stage of mixing, the spiral stirring blade 103 is compressed and does not participate in the mixing, avoiding the spiral stirring blade 103 from participating in the mixing during the cold mixing stage. This allows for two-stage mixing with different gradients to be completed without changing the equipment.

[0026] Please see Figure 3The mixing hopper 101 is connected to the X-type fastener 3 at its center. When raw materials are added to the mixing hopper 101, the weight of the motor 4 connected to both sides of the X-type fastener 3 and the mixing hopper 101 remains relatively balanced. Under the state of weight balance, the motor 4 and the mixing hopper 101 are driven to rotate, which can prevent the transmission rod 2 from bending due to uneven force during rotation. During the first stage of mixing, the transmission rod 2 does not drive the mixing hopper 101 to rotate, and the mixing hopper 101 and the motor 4 remain balanced. A reinforcing rod 5 is connected to the transmission rod 2 and connected to the end of the mixing hopper 101 to reinforce the fixation of the mixing hopper 101.

[0027] The adjustable shearing mechanism also includes a mixing rod 104, which slides through the mixing chamber 101 at the end away from the transmission assembly. (See also...) Figure 5 The mixing rod 104 extends into the mixing chamber 101 and is detachably connected to the transmission assembly. The end of the spiral stirring blade 103 near the transmission assembly is fixedly connected to the mixing rod 104, and the end of the spiral stirring blade 103 away from the transmission assembly is slidably connected to the mixing rod 104 and circumferentially fixed. When the mixing rod 104 is in contact with the transmission assembly, it can be driven by the transmission assembly to rotate.

[0028] When the mixing rod 104 extends into the mixing chamber 101 and engages with the transmission assembly, the two ends of the spiral stirring blades 103 approach the two ends of the mixing chamber 101. As the transmission assembly drives the mixing rod 104 to rotate, the spiral stirring blades 103 can stir the raw materials in the mixing chamber 101. Please refer to [link / reference]. Figure 5 The transmission assembly includes a docking seat 201, a docking shaft 202, and a linkage component 203. The docking seat 201 is fixedly connected to the mixing bin 101, and the docking shaft 202 is rotatably connected to the docking seat 201. Figure 5 The middle docking shaft 202 and the mixing rod 104 can be docked at one end that extends into the mixing bin 101. The mixing rod 104 extends into the docking seat 201 and is connected to the docking shaft 202. The linkage component 203 drives the docking shaft 202 and the output end of the motor 4. The linkage component 203 can use a chain or belt to drive the docking shaft 202 and the output end of the motor 4.

[0029] The cold water jacket 102 is connected to an inlet pipe and a drain pipe. The transmission rod 2 is hollow. Please refer to [link / reference needed]. Figure 3 Both the inlet and outlet pipes pass through the transmission rod 2 and are connected to the external heat exchange equipment. The water pipes are installed inside the transmission rod 2 to prevent the water pipes from getting tangled when the transmission rod 2 rotates. The inlet and outlet pipes extend out of the transmission rod 2 and are connected to the external heat exchange equipment to introduce cold water to cool the entire mixing bin 101. The raw materials can be cooled by contacting the wall of the mixing bin 101, thus realizing the mixing process in the cold mixing stage.

[0030] The mixing silo 101 is equipped with a material exchange port 105. Please refer to [link / reference]. Figures 1-4 The material changing port 105 is located on the mixing hopper 101 at the end away from the transmission rod 2. As the transmission rod 2 rotates, the material changing port 105 can face upward or downward. Since the mixing hopper 101 can rotate, feeding and discharging can be completed through one material changing port 105. The material changing port 105 can be rotated to the upper side for feeding, and rotated to the lower side for discharging.

[0031] Please see Figure 4 The spiral stirring blade 103 is composed of multiple spiral elastic metal strips, which are rotatably connected at staggered positions. When the spiral stirring blade 103 is stretched and opened, the metal strips rotate and bend, surrounding the mixing rod 104. In this embodiment, the spiral stirring blade 103 is made of elastic material. By stretching the spiral stirring blade 103, the bent metal strips can form a shape that surrounds the mixing rod 104 multiple times in the mixing chamber 101. When rotating, the raw materials can be stirred. At the same time, due to the compressibility of the spiral stirring blade 103, after being compressed into a disc shape, the mixing chamber 101 rotates without being sheared by the spiral stirring blade 103.

[0032] The mixing rod 104 is provided with a clamping groove 301, and a clamping component is provided at the end of the mixing chamber 101 away from the transmission component. The clamping component can be engaged with the clamping groove 301. After the clamping component is engaged with the clamping groove 301, the clamping groove 301 is rotatably connected to the clamping component, and the mixing rod 104 and the mixing chamber 101 are axially fixed. Please refer to [link / reference]. Figure 6 A docking groove 302 is fixedly connected to the mixing bin 101. Two clamping rings 303 are symmetrically slidably docked on the docking groove 302. The clamping rings 303 can be docked with the clamping groove 301. When the two clamping rings 303 are slidably docked with the docking groove 302, the clamping rings 303 can dock and fix the clamping groove 301. When the mixing rod 104 rotates, it fits against the clamping rings 303. A clamping groove 301 is also provided on the side of the mixing rod 104 near the docking shaft 202. After the docking shaft 202 is slidably pulled out in the mixing bin 101, the mixing rod 104 can be fixed by docking with the clamping groove 301.

[0033] Compared with the prior art, this embodiment provides a gradient closed homogenizing mixer. By setting a spiral stirring blade 103, the spiral stirring blade 103 can be formed into two states, a spiral stirring blade and a disc shape, through the stretching and compression of the mixing rod 104. After stretching, it can be used for stirring raw materials. When it is necessary to mix the raw materials by rotating the mixing chamber 101, the mixing rod 104 slides to compress the spiral stirring blade 103 into a disc shape. Thus, when rotating the mixing chamber 101, there will be no shearing effect on the raw materials. This realizes the mixing of two gradients in one mixing chamber 101 without moving the raw materials between two devices, performing hot mixing and cold mixing in sequence, avoiding the changes that may be caused when the raw materials are moved between two devices.

[0034] Example 2 Please see Figure 7 The spiral stirring blade 103 can be configured as multiple rigid arc-shaped metal sheets that are connected end to end. After the spiral stirring blade 103 is pulled, the arc-shaped metal sheets can rotate to form multiple inclined arc-shaped stirring blades. When the mixing rod 104 rotates, it drives the arc-shaped metal sheets to rotate for mixing.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of protection of the claims of the present invention.
