Description

Technical Field

[0001] This application relates to the field of paper production, and in particular to a stone paper sheet extrusion production equipment. Background Technology

[0002] Environmentally friendly stone paper is a new type of environmentally friendly material that falls between paper and plastic. It can replace some traditional functional papers, professional papers, and most plastic packaging materials. The main raw material of stone paper is calcium carbonate, which accounts for about 70-80%, supplemented by high molecular polymers. This paper looks no different from traditional paper, but it is more tough, not easy to tear, and has waterproof, oil-proof, and non-toxic properties.

[0003] Existing extrusion production equipment for stone paper includes a feeding system, a preheating system, a main extruder, an auxiliary extruder, a die, a cooling and shaping device, and a traction cutting device. The feeding system is used to feed the mixture of stone powder and resin into the preheating system. The preheating system preheats the material with a heater to achieve a suitable viscosity, and then it is extruded from the die. The auxiliary extruder is used to assist in adding functional additives, such as toughening agents and lubricants, to further improve the physical properties of the product.

[0004] In actual operation, the mixture of stone powder and resin is fed into the feeding system in proportion. The material system generally consists of a feed hopper and a feeding auger. When the mixture is fed into the feed hopper, the lime and resin may not mix evenly. Then, it is directly fed into the main extruder by the feeding auger, resulting in quality problems in the extruded product. Utility Model Content

[0005] The purpose of this application is to address the issue mentioned in the background art where, when the mixture is fed into the hopper, lime and resin may not mix evenly, and then be directly fed into the main extruder by the feeding auger, resulting in quality problems in the extruded product. This application provides a stone paper sheet extrusion production equipment.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A stone paper sheet extrusion production equipment includes a support base, an extrusion tube fixed on the support base, an extrusion motor fixed at one end of the extrusion tube, an extrusion auger fixed at the output end of the extrusion motor, the extrusion auger being located inside the extrusion tube, a feed hopper fixed on the extrusion tube, a feeding auger installed inside the feed hopper, an auxiliary mixing mechanism provided on one side of the support base, and an auxiliary feeding mechanism provided between the auxiliary mixing mechanism and the support base.

[0008] By adopting the above technical solution, stone powder and resin are mixed in a certain proportion, and then the stone powder and resin are poured into the auxiliary mixing mechanism. The auxiliary mixing mechanism fully mixes the stone powder and resin, and then the mixture is discharged onto the auxiliary feeding mechanism. The auxiliary feeding mechanism moves the mixture into the feed hopper at a higher position, so that the stone powder and resin can be fully and evenly mixed, reducing the possibility of product quality problems caused by uneven mixing.

[0009] Furthermore, the auxiliary mixing mechanism includes a mixing tank disposed on one side of the support base, a feeding port on the mixing tank, a support ring fixed on the mixing tank, four symmetrical support legs fixed on the support ring, a stirring motor fixed on the mixing tank, the output end of the stirring motor passing through the mixing tank and fixed with a stirring shaft, a mixing component disposed on the stirring shaft, a discharge port on the bottom of the mixing tank, and a discharge component disposed at the bottom of the mixing tank.

[0010] By adopting the above technical solution, the stirring shaft drives the mixing component to stir and mix the mixture in the mixing tank, and then the mixture is discharged from the discharge port of the mixing tank under the action of the discharge component. This allows the mixture of lime and resin to be fully mixed, reducing the possibility of uneven mixing affecting the quality of the extruded product.

[0011] Furthermore, the mixing assembly includes two symmetrically fixed stirring rods on a stirring shaft, the stirring rods abutting against the inner wall of the mixing tank, and a stirring mesh frame fixed on the stirring rods.

[0012] By adopting the above technical solution, the stirring shaft drives the stirring rod, and the stirring drives the stirring mesh frame to perform transverse stirring of the mixture in the mixing tank, thereby facilitating the transverse stirring of the materials in the mixing tank.

[0013] Furthermore, a stirring drum is provided inside the mixing tank, and a stirring auger is fixed on the stirring shaft, with the stirring auger located inside the stirring drum.

[0014] By adopting the above technical solution, the stirring shaft drives the stirring auger, which in turn moves the mixture from the bottom of the mixing drum upwards, thus facilitating the tumbling of the mixture.

[0015] Furthermore, two symmetrical support blocks are fixed at the bottom of the stirring drum, and the support blocks are fixedly connected to the mixing tank.

[0016] By adopting the above technical solution, two support blocks are used to support the mixing drum, which makes it easier for the mixed materials to enter the mixing drum from the bottom.

[0017] Furthermore, the discharge assembly includes two symmetrically fixed sliding rails at the bottom of the mixing tank, with a baffle slidably connected between the two sliding rails. The baffle corresponds to the discharge port at the bottom of the mixing tank. An electric telescopic rod is provided on one side of the mixing tank, and the telescopic end of the electric telescopic rod is fixedly connected to the baffle.

[0018] By adopting the above technical solution, the electric telescopic rod drives the baffle to move under the support of the sliding rail, which makes it easy to open the discharge port on the mixing tank and facilitate the passage of the mixed materials.

[0019] Furthermore, the bottom of the mixing tank is conical, and the discharge port of the mixing tank is located in the middle of the bottom.

[0020] By adopting the above technical solution, the mixed materials are gathered towards the middle of the bottom of the mixing tank due to the tilted bottom of the mixing tank. This facilitates the gathering of materials into the mixing drum, making it easier to move the mixed materials. At the same time, it also makes it easier for the mixed materials to fall from the discharge port during discharge.

[0021] Furthermore, the auxiliary feeding mechanism includes a feeding conveyor belt disposed between the feed hopper and the mixing tank. The feeding conveyor belt is bent, with one end fixedly connected to the feed hopper and the other end located at the bottom of the mixing tank and touching the bottom surface. Both sides of the feeding conveyor belt are fixedly surrounded by barriers. A discharge hopper is fixedly attached to the end of the feeding conveyor belt near the mixing tank, and the discharge hopper corresponds to the discharge port of the mixing tank. The electric telescopic rod is fixedly connected to the discharge hopper.

[0022] By adopting the above technical solution, the mixed material falls directly onto the feeding conveyor belt, which drives the mixed material to move towards the feed hopper. The mixed material falls directly from the feeding conveyor belt into the feed hopper, which makes it convenient to move the material to the higher feed hopper and reduces the inconvenience of pouring the mixture into the feed hopper.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. This application involves mixing stone powder and resin in a specific ratio, then pouring the stone powder and resin into the mixing tank through the feeding port. A stirring motor drives the stirring shaft to rotate, which in turn drives the stirring rod, which in turn drives the stirring mesh frame to rotate. As the stirring mesh frame rotates, it stirs the mixture of stone powder and resin. Simultaneously, under the action of the inclined surface at the bottom of the mixing tank, the mixture moves towards the center of the bottom of the mixing tank, then passes between the support blocks. The stirring shaft drives the stirring auger, which in turn drives the mixture to rise along the mixing drum. When the mixture reaches the highest point of the mixing drum, it falls from the outside of the drum, allowing the mixture to tumble up and down. After the mixture of lime and resin is fully mixed, the purpose of ensuring thorough mixing and reducing the possibility of uneven mixing affecting the quality of the extruded product is achieved.

[0025] 2. In this application, when the mixed material is discharged from the mixing tank, it falls directly onto the feeding conveyor belt. The feeding conveyor belt moves the mixed material towards the feed hopper. When the mixed material moves above the feed hopper, it falls directly from the feeding conveyor belt into the feed hopper. When the mixed material is discharged from the mixing tank, the feed hopper fixed on the feeding conveyor belt restricts the mixed material, reducing the possibility of the mixed material falling outside the feeding conveyor belt. Then, the fixed barriers on both sides of the feeding conveyor belt further limit the mixed material, achieving the purpose of facilitating the movement of materials to a higher feed hopper and reducing the inconvenience of pouring the mixture into the feed hopper.

[0032] The following is in conjunction with the appendix Figure 1 —4 provides further detailed description of this application.

[0033] This application discloses a stone paper sheet extrusion production equipment.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A stone paper sheet extrusion production equipment includes a support base 1, an extrusion tube 2 fixed on the support base 1, an extrusion motor 3 fixed at one end of the extrusion tube 2, an extrusion auger 4 fixed at the output end of the extrusion motor 3, the extrusion auger 4 being located inside the extrusion tube 2, a feed hopper 5 fixed on the extrusion tube 2, a feeding auger 8 installed inside the feed hopper 5, an auxiliary mixing mechanism 6 provided on one side of the support base 1, and an auxiliary feeding mechanism 7 provided between the auxiliary mixing mechanism 6 and the support base 1.

[0035] When using this extrusion equipment, stone powder and resin are first mixed in proportion, and then the stone powder and resin are poured into the auxiliary mixing mechanism 6. The auxiliary mixing mechanism 6 mixes the stone powder and resin thoroughly, and then the mixture is discharged onto the auxiliary feeding mechanism 7. The auxiliary feeding mechanism 7 moves the mixture to the feed hopper 5 at a higher position. Then, under the uniform rotation of the feeding auger 8, the mixture enters the extrusion tube 2 at a uniform speed. The extrusion motor 3 drives the extrusion auger 4 to rotate, allowing the mixture to move along the extrusion tube 2. Then, the mixture is melted by the heating device installed in the extrusion tube 2, and finally extruded from the extrusion head on the extrusion tube 2. By pouring the mixture of stone powder and resin into the auxiliary mixing mechanism 6 for stirring before feeding it into the feed hopper 5, the stone powder and resin can be fully and evenly mixed, reducing the possibility of product quality problems caused by uneven mixing.

[0036] Reference Figure 2 , Figure 3 and Figure 4The auxiliary mixing mechanism 6 includes a mixing tank 61 disposed on one side of the support base 1. The mixing tank 61 has a feeding port. A support ring 62 is fixed on the mixing tank 61. Four symmetrical support legs 63 are fixed on the support ring 62. A stirring motor 65 is fixed on the mixing tank 61. The output end of the stirring motor 65 passes through the mixing tank 61 and is fixed with a stirring shaft 64. A mixing component 66 is disposed on the stirring shaft 64. A discharge port is disposed at the bottom of the mixing tank 61. A discharge component 67 is disposed at the bottom of the mixing tank 61.

[0037] In addition, the mixing assembly 66 includes two symmetrically fixed stirring rods 661 on the stirring shaft 64. The stirring rods 661 abut against the inner wall of the mixing tank 61, and a stirring mesh frame 662 is fixed on the stirring rods 661.

[0038] Furthermore, a stirring drum 664 is provided inside the mixing tank 61, and a stirring auger 663 is fixed on the stirring shaft 64, with the stirring auger 663 located inside the stirring drum 664.

[0039] Furthermore, two symmetrical support blocks 665 are fixed at the bottom of the stirring drum 664, and the support blocks 665 are fixedly connected to the mixing tank 61.

[0040] Furthermore, the discharge assembly 67 includes two symmetrically fixed sliding rails 673 at the bottom of the mixing tank 61, and a baffle 671 is slidably connected between the two sliding rails 673. The baffle 671 corresponds to the discharge port at the bottom of the mixing tank 61. An electric telescopic rod 672 is provided on one side of the mixing tank 61, and the telescopic end of the electric telescopic rod 672 is fixedly connected to the baffle 671.

[0041] Furthermore, the bottom of the mixing tank 61 is conical, and the discharge port of the mixing tank 61 is located in the middle of the bottom.

[0042] Stone powder and resin are mixed in a specific ratio, and then poured into mixing tank 61 through the feeding port. A stirring motor 65 drives a stirring shaft 64 to rotate, which in turn drives a stirring rod 661. The stirring rod 661 then drives a stirring mesh frame 662 to rotate. As the mesh frame 662 rotates, it stirs the mixture of stone powder and resin. Simultaneously, under the influence of the inclined surface at the bottom of mixing tank 61, the mixture moves towards the center of the bottom of mixing tank 61, passing between the mixture support blocks 665. The stirring shaft 64 drives a stirring auger 663, which in turn lifts the mixture upwards along the mixing drum 664, allowing the mixture to move to the mixing drum 664. At its highest point, the mixture falls from outside the mixing drum 664, allowing the mixture to tumble up and down. After the lime and resin mixture is fully mixed, the electric telescopic rod 672 drives the baffle 671, which moves away from the discharge port at the bottom of the mixing tank 61 under the support of the sliding rail 673. The mixed mixture is then discharged from the mixing tank 61. By adding the lime and resin mixture into the mixing tank 61 and then using the stirring rod 661 to drive the stirring mesh frame 662 to stir the mixture, while the stirring auger 663 tumbles the mixture up and down, the lime and resin mixture can be fully mixed, reducing the possibility of uneven mixing affecting the quality of the extruded product.

[0043] Reference Figure 1 , Figure 2 and Figure 3The auxiliary feeding mechanism 7 includes a feeding conveyor belt 71 disposed between the feed hopper 5 and the mixing tank 61. The feeding conveyor belt 71 is bent. One end of the feeding conveyor belt 71 is fixedly connected to the feed hopper 5, and the other end of the feeding conveyor belt 71 is located at the bottom of the mixing tank 61 and abuts against the bottom surface. Both sides of the feeding conveyor belt 71 are fixed with guardrails 73. A discharge hopper 72 is fixed at the end of the feeding conveyor belt 71 near the mixing tank 61. The discharge hopper 72 corresponds to the discharge port of the mixing tank 61. An electric telescopic rod 672 is fixedly connected to the discharge hopper 72. When the mixture is discharged from the mixing tank 61, it falls directly onto the feeding conveyor belt 71. The feeding conveyor belt 71 moves the mixture towards the feed hopper 5. When the mixture moves above the feed hopper 5, it falls directly from the feeding conveyor belt 71 into the feed hopper 5. When the mixture is discharged from the mixing tank 61, the unloading hopper 72 fixed on the feeding conveyor belt 71 restricts the mixture, reducing the possibility of the mixture falling outside the feeding conveyor belt 71. Then, the barriers 73 fixed on both sides of the feeding conveyor belt 71 further limit the mixture. By allowing the mixture discharged from the mixing tank 61 to fall onto the feeding conveyor belt 71 under the restriction of the unloading hopper 72, and then the feeding conveyor belt 71 moves the mixture into the feed hopper 5, it is possible to easily move the material into the higher feed hopper 5, reducing the inconvenience of pouring the mixture into the feed hopper 5.

[0044] Working principle: Stone powder and resin are mixed in a certain proportion, and then poured into mixing tank 61 through the feeding port. The stirring motor 65 drives the stirring shaft 64 to rotate, which in turn drives the stirring rod 661. The stirring rod 661 then drives the stirring mesh frame 662 to rotate. As the mesh frame 662 rotates, it stirs the mixture of stone powder and resin. Simultaneously, under the action of the inclined surface at the bottom of mixing tank 61, the mixture moves towards the center of the bottom of mixing tank 61, then passes between the support blocks 665. The stirring shaft 64 drives the stirring auger 663, which in turn moves the mixture upwards along the mixing drum 664. When the mixture reaches the highest point of the mixing drum 664, it falls from the outside of the mixing drum 664, allowing the mixture to tumble and rotate. After the materials are mixed, the electric telescopic rod 672 drives the baffle 671, which moves away from the discharge port at the bottom of the mixing tank 61 under the support of the sliding rail 673. Then the mixed materials are discharged from the mixing tank 61. Under the restriction of the feeding hopper 72, the mixed materials fall directly onto the feeding conveyor belt 71. The feeding conveyor belt 71 drives the mixed materials to move towards the feeding hopper 5. When the mixed materials move above the feeding hopper 5, they fall directly from the feeding conveyor belt 71 into the feeding hopper 5. Then, under the uniform rotation of the feeding auger 8, the mixed materials enter the extrusion tube 2 at a uniform speed. The extrusion motor 3 drives the extrusion auger 4 to rotate, allowing the mixed materials to move along the extrusion tube 2. Then, the mixed materials are melted by the heating device installed in the extrusion tube 2, and finally extruded from the extrusion head on the extrusion tube 2.
