Description

Technical Field

[0001] This utility model relates to the technical field of biodegradable plastic product manufacturing equipment, and in particular to a raw material mixer for biodegradable plastic product manufacturing. Background Technology

[0002] In the production of biodegradable plastic products, raw material mixing is a crucial step, as the uniformity of the mixture directly affects the quality and performance of the final product. Currently, most commercially available raw material mixing equipment employs a blade-type mixing structure, achieving mixing by driving the blades to rotate at high speed within the mixing tank. However, this traditional mixing method has significant drawbacks: the mixing range of the blades is limited, and dead zones easily form at the inner edges and bottom corners of the mixing tank, resulting in some raw materials not being fully mixed. This leads to uneven mixing and negatively impacts the production quality of biodegradable plastic products.

[0003] When using the above technology, the following technical problems were found in the existing technology: First, most of the existing technologies use a fixed bucket and a stirring paddle to mix the raw materials, which will cause the problem of dead corners in the mixing process. Therefore, this device uses the rotation of the drum to drive the internal raw materials to tumble and achieve mixing. This method can effectively reduce the dead corners in the mixing and improve the mixing uniformity. Secondly, in actual operation, existing drum-type mixing equipment relies mainly on the drum's own weight and contact with the drive wheel to transmit power. During rapid rotation, due to factors such as centrifugal force and uneven distribution of raw materials, the drum is prone to derailment and shaking. The lack of an effective limiting mechanism to constrain the drum's running trajectory not only affects the stability of the mixing process but may also cause equipment failure. To address this, we have designed a biodegradable plastic product raw material mixer to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a raw material mixing machine for the production of biodegradable plastic products, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A raw material mixer for biodegradable plastic products includes a support platform. Each of the four ends of the top of the support platform is fixed with a bearing seat. A drive gear is rotatably connected to the inner side of the bearing seat. A mixing drum is assembled at the top of the support platform. Arc-shaped racks are fixed at both ends of the outer side of the mixing drum. The inner side of the arc-shaped racks is meshed with two drive gears at the same end.

[0006] The support platform has a feed inlet on its outer side, and an arc-shaped roller cover is rotatably connected to one side of the feed inlet via a hinge. The outer side of the arc-shaped roller cover is fixed to the support platform by a buckle.

[0007] The mixing drum has a discharge hopper fixed at one end, and a spiral pattern is fixed on the outside of the discharge hopper and at one end of the mixing drum. A discharge cover is threaded onto the outside of the spiral pattern.

[0008] The mixing drum has a second mixing slurry fixed on its inner surface, a stirring slurry fixed on its inner side and at its axial center, and a first mixing slurry fixed on its outer side.

[0009] The other end of the mixing drum is equipped with a servo motor, the output end of which passes through the mixing drum and is fixed to the agitator. The rotation direction of the agitator and the mixing impeller is opposite to that of the mixing drum and the mixing impeller.

[0010] Among them, the two drive gears on the same side are fixed together by a transmission rod, and one end of one of the shaft seats is equipped with a servo motor two. The output end of the servo motor two passes through one of the shaft seats and is fixed to one of the drive gears.

[0011] The mixing drum has arc-shaped guide rails fixed at both ends of its outer side and between the two arc-shaped racks.

[0012] The support platform has fixed bases at both ends on its inner side, and side plates are fixed at both ends of the top of the fixed bases. Auxiliary wheels are rotatably connected to both sides between the two side plates, and the top of the auxiliary wheels is rotatably connected to the inner side of the arc-shaped guide rail.

[0013] In this configuration, each of the two side plates has a limiting claw fixed at one end that is far apart from the other, and the inner side of the limiting claw is slidably connected to the outer side of the arc-shaped guide rail.

[0014] The outer ends of the arc-shaped guide rail are provided with limit grooves, and the inner side of the limit groove is slidably connected to the limit claw.

[0015] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by using a mixing drum to rotate and drive the raw materials to tumble, and with the opposite rotation design of the stirring paddle, mixing paddle one and mixing drum, mixing paddle two, a bidirectional shearing and tumbling action is formed, which effectively reduces the mixing dead angle and greatly improves the uniformity of raw material mixing. The combination of arc-shaped guide rails, auxiliary wheels, limiting claws, and limiting grooves creates a limiting structure that counteracts the effects of centrifugal force and uneven material distribution, preventing the mixing drum from derailing or shaking and reducing the risk of equipment failure.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figure 1-7This utility model provides a technical solution: a raw material mixer for biodegradable plastic products, including a support platform 1, with four ends of the top of the support platform 1 fixed with bearing seats 19, and drive gears 10 rotatably connected to the inner side of the bearing seats 19. A mixing drum 2 is assembled at the top of the support platform 1, and arc-shaped racks 4 are fixed at both ends of the outer side of the mixing drum 2. The inner side of the arc-shaped racks 4 is meshed with two drive gears 10 at the same end. A feed inlet is opened on the outer side of the support platform 1, and an arc-shaped roll cover 3 is rotatably connected to one side of the feed inlet through a hinge. The outer side of the arc-shaped roll cover 3 is fixed to the support platform 1 by a buckle. Before mixing the raw materials, feed them through the feed port on the outside of the support platform 1, and open the arc-shaped roller cover 3 which is connected to the feed port by a hinge. Pour the biodegradable plastic production raw materials to be mixed into the mixing drum 2. After feeding, fix the arc-shaped roller cover 3 to the support platform 1 by the buckle on the outside of the roller cover 3 to ensure that the raw materials will not leak during the mixing process. A discharge hopper 7 is fixed at one end of the mixing drum 2. A spiral pattern is fixed on the outer side of the discharge hopper 7 and at one end of the mixing drum 2. A discharge cover 8 is threaded on the outer side of the spiral pattern. A mixing slurry 18 is fixed on the inner surface of the mixing drum 2. An agitator 17 is fixed on the inner side of the mixing drum 2 and at the axial center. A mixing slurry 11 is fixed on the outer side of the agitator 17. The other end of the mixing drum 2 is equipped with a servo motor 6. The output end of the servo motor 6 passes through the mixing drum 2 and is fixed to the agitator 17. The rotation direction of the agitator 17 and the mixing blade 11 is opposite to that of the mixing drum 2 and the mixing blade 18. The device adopts a two-way mixing structure of "drum rotation and internal stirring". After the servo motor 6 installed at the other end of the mixing drum 2 is started, its output end passes through the mixing drum 2 and is fixed to the stirring blade 17 at the shaft center, driving the stirring blade 17 and the mixing blade 11 on the outside to rotate synchronously. The key is that the rotation direction of the stirring paddle 17 and the mixing paddle 11 is opposite to that of the mixing drum 2 and the mixing paddle 18 fixed on the inner surface, forming a bidirectional shearing and tumbling effect, which greatly improves the uniformity of raw material mixing. Two drive gears 10 on the same side are fixed together by a transmission rod. One end of one of the bearings 19 is equipped with a servo motor 9. The output end of the servo motor 9 passes through one of the bearings 19 and is fixed to one of the drive gears 10. Arc-shaped guide rails 5 are fixed at both ends of the outer side of the mixing drum 2 and between the two arc-shaped racks 4; During the raw material mixing stage, the power is provided by servo motor 29, whose output end passes through the shaft seat 19 and is fixedly connected to the drive gear 10. After starting, it drives the drive gear 10 to rotate around the inner side of the shaft seat 19. Since the arc-shaped racks 4 at both ends of the outer side of the mixing drum 2 mesh with the two drive gears 10 at the same end, the rotational force of the drive gear 10 is converted into the circumferential motion of the mixing drum 2, so that the mixing drum 2 rotates stably at the top of the support platform 1. The rotation of the drum drives the internal raw materials to tumble, reducing the dead corners of mixing. Both ends of the inner side of the support platform 1 are fixed with a fixed seat 12, and both ends of the top of the fixed seat 12 are fixed with a side plate 13. Auxiliary wheels 16 are rotatably connected to both sides between the two side plates 13. The top of the auxiliary wheel 16 is rotatably connected to the inner side of the arc-shaped guide rail 5. Limiting claws 14 are fixed at the ends of the two side plates 13 that are far apart from each other. The inner side of the limiting claws 14 is slidably connected to the outer side of the arc-shaped guide rail 5. Limiting grooves 15 are opened at both ends of the outer side of the arc-shaped guide rail 5. The inner side of the limiting grooves 15 is slidably connected to the limiting claws 14. Specifically, addressing the issues of derailment and swaying in traditional drum mixers, this device achieves stable constraint through the cooperation of arc-shaped guide rails 5 and limiting components. The arc-shaped guide rails 5, fixed at both ends of the outer side of the mixing drum 2 and between the two arc-shaped racks 4, are rotatably connected to the auxiliary wheel 16 between the inner side of the guide rails 5 and the top side plate 13 of the inner side fixed seat 12 of the support platform 1. The auxiliary wheel 16 provides support and guidance for the drum rotation. At the same time, the limiting claws 14 on the outer side of the side plate 13 are slidably connected to the outer side of the arc-shaped guide rails 5, and the limiting grooves 15 at both ends of the outer side of the arc-shaped guide rails 5 are precisely matched with the limiting claws 14 to form double limiting, effectively offsetting the swaying caused by centrifugal force and uneven material distribution, preventing the drum from derailing, and ensuring the stability of the mixing process. Therefore, after the above raw materials are mixed, the discharge cover 8 on the outside of the discharge hopper 7 at one end of the mixing drum 2 is unscrewed (the discharge hopper is threaded to the discharge cover 8 through a spiral thread), and the mixing drum 2 is kept rotating. Under the combined action of gravity and the rotation force of the drum, the uniformly mixed raw materials inside are discharged through the discharge hopper 7, thus completing the entire mixing process.

[0022] The usage process of the biodegradable plastic product raw material mixer provided by this utility model is as follows: Open the arc-shaped roller cover 3 at the feed inlet of the support platform 1, inject the raw material to be mixed into the mixing drum 2, and fix the arc-shaped roller cover 3 with the buckle after feeding to prevent the raw material from leaking. Servo motor 29 is started, and its output end drives the drive gear 10 inside the shaft seat 19 to rotate. The drive gear 10 meshes with the arc-shaped rack 4 on the outside of the mixing drum 2, converting the rotational force into the circumferential motion of the mixing drum 2, so that the mixing drum 2 rotates stably. At the same time, servo motor 16 is started, and its output end drives the stirring paddle 17 at the shaft center of the mixing drum 2 and the mixing paddle 11 on the outside to rotate synchronously. The stirring paddle 17 and the mixing paddle 11 rotate in the opposite direction to the mixing drum 2 and the inner mixing paddle 28. Furthermore, when the mixing drum 2 rotates, the auxiliary wheel 16 between the outer arc-shaped guide rail 5 and the upper side plate 13 of the inner fixed seat 12 of the support platform 1 rotates and cooperates to provide support and guidance. At the same time, the limiting claw 14 on the side plate 13 is slidably connected to the outer side of the arc-shaped guide rail 5, and the limiting claw 14 is embedded in the limiting groove 15 of the arc-shaped guide rail 5 to form a double limiting. After mixing is complete, unscrew the discharge cover 8 on the outside of the discharge hopper 7, keep the mixing drum 2 rotating, and the raw materials are discharged through the discharge hopper 7 under the combined action of gravity and rotational force.

[0023] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
