Description

Technical Field

[0001] This invention belongs to the field of kneading machine technology, specifically relating to a multi-screw discharge kneading machine. Background Technology

[0002] A kneader is a special type of high-power mixing equipment, mainly used for stirring, mixing, kneading, crushing, polymerizing, vulcanizing and other processes of high-viscosity and high-elasticity plastic materials.

[0003] A screw-discharge kneader is a mixing device that integrates a screw extrusion unit as the main discharge method on the basis of a standard kneader. It uses a vertical or inclined screw installed at the bottom to force, continuously and controllably discharge high-viscosity, paste-like or viscous materials that have been uniformly mixed by the kneader from the mixing tank.

[0004] Currently, most screw-discharge kneaders lack a barrier structure between the mixing tank and the screw discharge port, which causes materials to fall to the discharge port without being mixed and kneaded when they enter the kneader, affecting the processing effect of the materials. At the same time, the extrusion dies of existing kneaders are generally fixed, which is inconvenient for installation and disassembly, and it is also inconvenient to quickly change the templates that form materials of different shapes.

[0016] Compared with existing technologies, this invention provides a versatile screw-discharge kneader with the following advantages: 1. In this invention, the W-shaped mixing groove inside the kneading box is used for material processing, the groove facilitates material discharge, the box cover improves the sealing effect of the kneading box to prevent material from splashing out during processing, the feed pipe facilitates the entry of material into the kneading box, and the kneading discharge mechanism facilitates the stirring, mixing and kneading of the material entering the kneading box, while also facilitating the discharge of processed material and distinguishing between the kneading and discharge steps to prevent unprocessed material from being discharged directly. The extrusion molding mechanism facilitates the extrusion molding of the discharged material, and also facilitates installation and disassembly, improving the performance of the kneader.

[0017] 2. In this invention, the inlet and groove on the discharge pipe are compatible. The inlet facilitates the entry of processed materials into the discharge pipe, and the discharge screw facilitates the extrusion and discharge of the processed materials. The rotating handle facilitates the rotation of the discharge pipe. When the inlet of the discharge pipe rotates to face the groove below, it prevents materials inside the kneading box from falling into the discharge pipe, thus avoiding material processing quality problems and improving the kneading machine's performance. The positioning hole on the rotating handle and the positioning plate on the kneading box facilitate the positioning of the rotated discharge pipe, improving its operational stability. The drive motor facilitates the rotation of the Z-shaped paddle, thereby facilitating the processing of materials inside the W-shaped mixing tank and improving the kneading machine's processing efficiency.

[0018] 3. In this invention, the synchronous pulley and synchronous belt facilitate the rotation of the discharge screw following the axis of the Z-shaped blade, improving the ease of use of the discharge assembly. The limiting ring improves the stability of the discharge pipe. The protective cover protects the synchronous pulley and synchronous belt, improving their safety. At the same time, the protective cover limits the rotation handle, allowing it to accurately switch from one positioning plate to another during use, thus improving its performance.

[0019] 4. In this invention, the inner wall of the discharge sleeve and the outer wall of the discharge pipe are adapted to each other, and the connecting pipe and the discharge sleeve are threadedly connected, which facilitates the installation and disassembly of the die head and improves its maintenance convenience. The inner diameters of the connecting pipe and the discharge pipe are consistent to avoid material blockage. The template facilitates material forming. The extrusion hole shapes of multiple templates are not consistent. The mounting plate rotates on the fixing screw on the die head, which facilitates the rotation of multiple templates around the fixing screw, thereby facilitating the rapid switching of multiple templates and improving the diversity and performance of the extrusion molding mechanism.

[0020] 5. In this invention, the clamping plate is fixedly connected to the mold head via an elastic connecting plate, and the fixing screw passes through the clamping plate. The clamping plate can swing freely via the elastic connecting plate, which facilitates the switching of the template. A positioning groove is provided on the side wall of the clamping plate near the mold head. The positioning groove facilitates the positioning of the template that is rotated between the mold head and the clamping plate. The clamping plate is pressured by the fastening nut and the fixing screw, thereby improving the positioning effect of the clamping plate on the template. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example

[0025] Please see Figure 1-8 The present invention provides the following technical solutions: A multi-screw discharge kneader comprises a kneading box 1, a kneading discharge mechanism, and an extrusion molding mechanism. The kneading discharge mechanism is mounted on the kneading box 1, and the extrusion molding mechanism is mounted on the kneading discharge mechanism. A W-shaped mixing trough is provided inside the kneading box 1, and a groove is provided on the inner wall of the W-shaped mixing trough. A box cover 7 is hinged to the top of the kneading box 1, and a feed pipe 8 is connected to the top of the box cover 7. In this embodiment, the W-shaped mixing groove inside the kneading box 1 is used for material processing, the groove facilitates material discharge, the box cover 7 improves the sealing effect of the kneading box 1 to prevent material from splashing out during processing, the feed pipe 8 facilitates the entry of material into the kneading box 1, and the kneading discharge mechanism facilitates the stirring, mixing and kneading of the material entering the kneading box 1, while also facilitating the discharge of processed material and distinguishing between the kneading and discharge steps to prevent unprocessed material from being discharged directly. The extrusion molding mechanism facilitates the extrusion molding of the discharged material, and also facilitates installation and disassembly, improving the performance of the kneader.

[0026] Please see Figure 1-5 The kneading box 1 is equipped with a kneading and discharging mechanism for mixing, kneading, and discharging. The kneading box 1 consists of a discharging component 2 and a kneading component 3, as described in detail below: The discharge assembly 2 is set in the groove and is used for the discharge and control of the processed material. Specifically, the discharge assembly 2 includes a discharge pipe 201, a discharge screw 202, a rotating handle 203 and a positioning plate 204. The discharge pipe 201 is rotatably embedded between the inner walls of the groove. An inlet is opened on one side of the outer wall of the discharge pipe 201. The discharge screw 202 is rotatably embedded on the inner wall of the discharge pipe 201. The rotating handle 203 is hinged to one end of the discharge pipe 201. A positioning hole is opened on one side of the outer wall of the rotating handle 203. There are two positioning plates 204. Each positioning plate 204 is fixedly connected to one side of the outer wall of the kneading box 1. The kneading component 3 is installed on the kneading box 1 and is used for mixing and kneading materials. Specifically, the kneading component 3 includes Z-shaped blades 301 and drive motors 302. There are two Z-shaped blades 301. Each Z-shaped blade 301 is rotatably embedded between the inner walls of the kneading box 1 via a rotating shaft. There are two drive motors 302. Each drive motor 302 is fixedly installed on one side of the outer wall of the kneading box 1. The output end of each drive motor 302 is fixedly connected to one end of the rotating shaft of the corresponding Z-shaped blade 301.

[0027] In this embodiment, the discharge pipe 201 is rotatably installed in the groove. The inlet on the discharge pipe 201 is adapted to the groove opening, allowing the processed material to easily enter the discharge pipe 201 through the inlet. The discharge screw 202 facilitates the extrusion and discharge of the processed material. The rotating handle 203 facilitates the rotation of the discharge pipe 201. When the inlet of the discharge pipe 201 rotates to face the bottom of the groove, it prevents the material inside the kneading box 1 from falling into the discharge pipe 201, thus avoiding material processing quality problems and improving the kneading machine's performance. The positioning hole on the rotating handle 203 cooperates with the positioning plate 204 on the kneading box 1 to facilitate the positioning of the rotated discharge pipe 201, improving its operational stability. The drive motor 302 facilitates the rotation of the Z-shaped paddle 301, thereby facilitating the processing of the material inside the W-shaped mixing tank and improving the kneading machine's processing efficiency.

[0028] Please see Figure 3-4 The discharge screw 202 and one of the Z-shaped blades 301 are connected by a synchronous pulley and a synchronous belt drive.

[0029] In this embodiment, the discharge screw 202 is made easier to rotate with the shaft of the Z-shaped blade 301 by means of a timing pulley and timing belt, thereby improving the ease of use of the discharge assembly 2.

[0030] Please see Figure 3 and Figure 5 The discharge assembly 2 also includes a limiting ring 205, which is fixedly sleeved on the outer surface of the discharge pipe 201; The kneading assembly 3 also includes a protective cover 303, which is fixedly installed on the outer wall of one side of the kneading box 1.

[0031] In this embodiment, the limiting ring 205 improves the stability of the discharge pipe 201, and the protective cover 303 facilitates the protection of the timing pulley and timing belt, improving their safety. At the same time, the protective cover 303 facilitates the limiting of the rotating handle 203, allowing it to be accurately switched from one positioning plate 204 to another during use, thus improving its performance.

[0032] Please see Figure 1-2 and Figure 5-8 The kneading and discharging mechanism is equipped with an extrusion molding mechanism for extruding and molding materials. The extrusion molding mechanism consists of a discharge sleeve 4, a die head disassembly and assembly assembly 5, and a switching assembly 6, as described in detail below: The discharge sleeve 4 is fixedly installed on the outer wall of one side of the kneading box 1, and the discharge sleeve 4 is sleeved on the outer surface of the discharge pipe 201. The die head assembly 5 is set on the discharge sleeve 4 and is used to quickly assemble and disassemble the die head 502. Specifically, the die head assembly 5 includes a connecting pipe 501 and a die head 502. The connecting pipe 501 is threaded between the inner walls of the discharge sleeve 4 and the die head 502 is fixedly connected to one end of the connecting pipe 501. The switching component 6 is attached to the mold head disassembly and assembly 5, and is used for quick switching of the template 603. Specifically, the switching component 6 includes a fixing screw 601, an mounting plate 602 and a template 603. The fixing screw 601 is fixedly connected to the outer wall of one side of the mold head 502. The mounting plate 602 is rotatably sleeved on the outer surface of the fixing screw 601. Multiple templates 603 are provided, and each template 603 is fixedly connected to the outer wall of the mounting plate 602.

[0033] In this embodiment, the inner wall of the discharge sleeve 4 and the outer wall of the discharge pipe 201 are adapted to each other, and the connecting pipe 501 and the discharge sleeve 4 are threadedly connected, which facilitates the installation and disassembly of the die head 502 and improves its maintenance convenience. The inner diameters of the connecting pipe 501 and the discharge pipe 201 are the same to avoid material blockage. The template 603 facilitates material forming. The extrusion hole shapes of multiple templates 603 are not the same. The mounting plate 602 rotates on the fixing screw 601 on the die head 502, which facilitates the rotation of multiple templates 603 around the fixing screw 601, thereby facilitating the rapid switching of multiple templates 603 and improving the diversity and effectiveness of the extrusion molding mechanism.

[0034] Please see Figure 6-8 The switching component 6 also includes an elastic connecting plate 604 and a clamping plate 605. The elastic connecting plate 604 is fixedly connected to the outer wall of one side of the mold head 502, and the clamping plate 605 is fixedly connected to the outer wall of the elastic connecting plate 604. A fastening nut 606 is threaded on the outer surface of the fixing screw 601.

[0035] In this embodiment, the clamping plate 605 is fixedly connected to the mold head 504 via the elastic connecting plate 604, and the fixing screw 601 passes through the clamping plate 605. The clamping plate 605 can swing freely via the elastic connecting plate 604, which facilitates the switching of the template 603. A positioning groove is provided on the side wall of the clamping plate 605 near the mold head 504. The positioning groove facilitates the positioning of the template 603 that is rotated between the mold head 504 and the clamping plate 605. The clamping nut 606 and the fixing screw 601 cooperate to apply pressure to the clamping plate 605, thereby improving the positioning effect of the clamping plate 605 on the template 603.

[0036] Working principle: In the initial state, the handle 203 on the discharge pipe 201 is located at the lower positioning plate 204. During use, the handle 203 is rotated out from the lower positioning plate 204 and then rotated to the upper positioning plate 204, so that the positioning hole fits onto the upper positioning plate 204. At this time, the discharge pipe 201 will rotate with the handle 203, and its inlet will rotate to the bottom of the groove, sealing the groove opening through the discharge pipe 201. The box cover 7 is closed, and the material to be processed is fed into the kneading box 1 through the feed pipe 8. The drive motor 302 is started, driving the Z-shaped paddle 301 to rotate and process the material inside the W-shaped mixing tank. When processing is almost complete, the handle 203 is returned to its original position. At this time, the inlet on the discharge pipe 201 rotates to fit into the groove opening, and the processed material enters the discharge pipe 201 through the inlet. Leaf 301 continuously processes the material. Through the cooperation of the synchronous pulley and synchronous belt, it drives the discharge screw 202 inside the discharge pipe 201 to rotate, extruding the material inside the discharge pipe 201. When the material moves to the opening of the discharge sleeve 4, it will pass through the template 603 on the die head 502 for forming. When it is necessary to change the shape, first turn off the drive motor 302, loosen the fastening nut 606, pull the pressure plate 605 away from the die head 502, and rotate the mounting plate 602 on the fixing screw 601 so that the other template 603 rotates between the die head 502 and the pressure plate 605. After aligning the positioning grooves on the template 603 and the pressure plate 605, tighten the fastening nut 606, and then turn on the drive motor 302. When it is necessary to disassemble the die head 502 and the template 603, rotate the die head 502 and the connecting pipe 501 to remove them from the discharge sleeve 4.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
