Description

Technical Field

[0001] This utility model relates to the field of powder coating molding technology, and in particular to a powder coating extrusion molding device. Background Technology

[0002] Extrusion molding of powder coatings is a key step in the powder coating production process. Its function is to melt, shear, and mix uniformly mixed powder raw materials (including resin, curing agent, pigment, filler and additives, etc.) to form a uniform melt, which is then cooled and crushed to obtain pulverizable sheet material.

[0003] However, in the existing technology, the molded parts are cut during the powder coating extrusion molding process. Manual cutting is highly dependent on the operator's experience and reaction ability. It is easy for inaccurate human judgment to lead to inconsistent cutting lengths, which affects the consistency of finished products and production efficiency. Although mechanical cutting has a certain degree of automation, due to problems such as transmission error, mechanical wear or insufficient control precision, there are often obvious deviations in the length of each product segment. In addition, in some production processes, the extrusion and cutting links are not synchronized. It is often necessary to stop the machine after extrusion and perform manual cutting, which not only increases the number of operation steps, but also reduces the overall production cycle. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that manual cutting is highly dependent on the operator's experience and reaction ability, and is prone to inconsistent cutting lengths due to inaccurate human judgment, which affects the consistency of finished products and production efficiency. Therefore, a powder coating extrusion molding device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a powder coating extrusion molding device, including a support frame, an extruder installed on one side of the top of the support frame, and a cutting mechanism installed on the side wall of the support frame;

[0006] The cutting mechanism includes two support rods, with a central wheel rotatably connected between them. A limit groove is formed on the outer surface of the central wheel. A second fixed rod is fixedly connected to both sides of the outer surface of the central wheel. A swing rod is rotatably connected to the outer side of the second fixed rod. A mounting groove is formed in the middle of the two swing rods on opposite sides, and a spring is set between the two swing rods. Both ends of the spring are inserted into the mounting groove. A first fixed rod is fixedly connected to the top of the support rod, and a rotating wheel is rotatably connected to the outer surface of the top of the first fixed rod.

[0007] Preferably, a fixing block is fixedly connected to one end of the swing rod, and a cutter is fixedly connected to the inside of the fixing block.

[0008] Preferably, one end of the fixed block abuts against the rotating wheel, and a limit block is fixedly connected to the outer surface of the center wheel.

[0009] Preferably, one end of the support rod is fixedly connected to the side wall of the support frame.

[0010] Preferably, a drive motor is installed on one side of one of the support rods, and a rotating rod is fixedly connected to the output end of the drive motor.

[0011] Preferably, one end of the rotating rod is rotatably connected to the support rod, and the other end of the rotating rod is fixedly connected to the center of the central wheel.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, during the operation of the extruder, the molding material is first uniformly guided and extruded through the limiting groove to ensure stable size and shape. The rotation of the central wheel drives the two swing rods to swing symmetrically. After the fixed block at the front end of the swing rod contacts the rotating wheel, it moves towards the center under the guidance of the force. During the swing, the spring is compressed to provide rebound force and enhance cutting stability. At the end of the swing rod closing, the staggered cutter closes to complete synchronous cutting. The whole process is controlled by the rotation cycle of the central wheel to ensure that the timing and position of each cut are consistent, the length of the finished product is uniform, and it is beneficial to subsequent operations.

[0014] 2. In this invention, the elastic potential energy released by the spring drives the swing arm to automatically disperse to both sides, offering advantages of automation and continuity without the need for external driving components. To ensure the accuracy of the motion trajectory, the system sets limit blocks on both sides of the swing arm to effectively restrict its range of motion, guiding it to run along a predetermined path and preventing structural deviations that could cause operational instability or positioning errors. During the slitting stage, the drive motor provides rotational power, causing the rotating rod to rotate. Its rotational speed determines the material feeding rhythm and cutting length. By adjusting the motor speed, precise processing of products of different specifications can be achieved, improving the system's flexibility and adaptability. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1-4 As shown, this utility model provides a powder coating extrusion molding device, including a support frame 1, an extruder 2 installed on one side of the top of the support frame 1, and a cutting mechanism 4 installed on the side wall of the support frame 1;

[0023] The cutting mechanism 4 includes two support rods 41, and a central wheel 44 is rotatably connected between the two support rods 41. A limit groove 46 is formed on the outer surface of the center wheel 44. A second fixed rod 452 is fixedly connected to both sides of the outer surface of the center wheel 44. A swing rod 45 is rotatably connected to the outer side of the second fixed rod 452. A mounting groove 451 is formed in the middle of the two swing rods 45 facing each other, and a spring 48 is provided between the two swing rods 45. Both ends of the spring 48 are inserted into the inner side of the mounting groove 451. A first fixed rod 43 is fixedly connected to the top of the support rod 41, and a rotating wheel 431 is rotatably connected to the outer surface of the top end of the first fixed rod 43.

[0024] The specific settings and functions of this embodiment will be described in detail below. When extruding the material using the extruder 2, the material is first uniformly guided and extruded along the limiting groove 46 located at the equipment outlet to ensure the stability of its size and shape. During the continuous extrusion of the material, the central wheel 44 located in the forming path begins to rotate. The rotation of the central wheel 44 not only serves a transmission function, but also drives the two swing rods 45 on its surface to reciprocate through mechanical linkage.

[0025] Specifically, when the central wheel 44 completes one full rotation, the two swing arms 45 connected to it will also rotate symmetrically around the central axis. During this process, the front end fixing block 453 of the swing arm 45 will sequentially contact the rotating wheel 431 arranged on its movement path. Since there is a mechanical contact relationship between the fixing block 453 and the rotating wheel 431, when contact occurs, the rotating wheel 431 will provide a force, causing the two swing arms 45 to rotate synchronously towards the center under the guidance of the contact point.

[0026] As the two swing arms 45 gradually close, the springs 48 installed inside them are also subjected to compressive force, resulting in axial compression deformation. This spring compression not only provides a rebound force to ensure the subsequent reset of the mechanism, but also enhances the stability and consistency of the cutting process.

[0027] At the final stage of the closing action of the two swing arms 45, the staggered cutters 47 at their ends precisely close, thus synchronously cutting the extruded product. Since the entire driving and cutting process is controlled by the rotation cycle of the central wheel 44, the timing and position of each cut are highly consistent, ensuring that the length of each cut segment is exactly the same, greatly facilitating subsequent assembly, processing, or packaging processes. Furthermore, this cutting mechanism, through mechanical linkage and the cooperation of elastic elements, not only improves the stability of the overall structure but also enhances cutting accuracy and automation.

[0028] Example 2: Figure 1 and Figure 2 As shown, a fixing block 453 is fixedly connected to one end of the swing rod 45, and a cutter 47 is fixedly connected to the inner side of the fixing block 453. One end of the fixing block 453 abuts against the rotating wheel 431, and a limit block 49 is fixedly connected to the outer surface of the center wheel 44. One end of the support rod 41 is fixedly connected to the side wall of the support frame 1. A drive motor 3 is installed on one side of one of the support rods 41, and a rotating rod 42 is fixedly connected to the output end of the drive motor 3. One end of the rotating rod 42 is rotatably connected to the support rod 41, and the other end of the rotating rod 42 is fixedly connected to the middle of the center wheel 44.

[0029] The overall effect of this embodiment is that after the spring 48 connected to one end of the swing rod 45 completes its cutting action, the elastic potential energy of the spring 48 is released and converted into a driving force that pushes the two swing rods 45 to disperse to both sides. This dispersion process is automated and continuous, requiring no additional external driving components. To ensure that the swing rods 45 do not deviate from their original designed trajectory during the dispersion process, limiting blocks 49 are provided on both sides, serving as spatial constraints and position guidance. The limiting blocks 49 effectively limit the maximum range of movement of the swing rods 45, ensuring that they always run along the predetermined path when pushed by the elastic force of the spring 48, thereby preventing instability or repeated positioning errors in the overall operation of the device due to structural offset.

[0030] During the slitting stage of the finished product, the system provides rotational power through a drive motor 3, which is connected to a rotating rod 42, thereby driving the rotating rod 42 to rotate precisely at a set speed. The rotational speed of the rotating rod 42 directly determines the feeding rhythm and cutting length of the material when it is fed into the cutting device. By adjusting the speed parameters of the drive motor 3, the length of each slitting can be flexibly set, thus meeting the processing requirements of products with different specifications.

[0031] The operating method and working principle of this device are as follows: When extruding and molding using the extruder 2, the molded material is extruded along the limiting groove 46. During this process, the central wheel 44 begins to rotate, which in turn drives the surface swing rods 45 to move. When the central wheel 44 rotates one revolution, the two swing rods 45 will contact the rotating wheel 431. At this time, the fixed block 453 at one end of the swing rod 45, due to contact with the rotating wheel 431, will drive the two swing rods 45 to move and rotate synchronously and gradually close together, while simultaneously compressing the spring 48 inside the mounting groove 451, so that the spring 48 is in a compressed state. During the closing process, the two staggered cutters 47 can complete the cutting of the molded part, and the finished product length is the same each time, which facilitates subsequent processing.

[0032] After the swing rod 45 completes the cutting with the help of the spring 48, the elasticity of the spring 48 will push the two swing rods 45 to disperse. During this process, the swing rod 45 will be restricted by the limit block 49, thus ensuring that its initial position does not change.

[0033] In addition, when the finished product is cut, the drive motor 3 drives the rotating rod 42 to rotate. The rotation speed of the rotating rod 42 can determine the size of each cut, and thus can be adjusted according to the processing requirements.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
