[0002] Plastic is a material with high molecular weight synthetic resin as an important component. It can be molded into a certain shape under certain conditions and can keep the shape unchanged at room temperature. It has been widely used in various fields of industry, agriculture, national defense and national economy. With the rapid development of the plastics industry, plastic products are used more and more widely in daily life and industrial production. However, a large amount of plastic waste is also generated, causing serious pollution to the environment.

[0003] Recycling plastics and reprocessing them into useful products can not only reduce environmental pollution, but also achieve the recycling of resources. At present, the plastic recycling and molding equipment is through the steps of heating and dissolving the recycled plastics, pouring them into molds, extruding and cooling them; At present, there are the following disadvantages when recycling and extruding dissolved plastics: Among them, during the existing plastic extrusion molding process, its mold will generate a lot of high temperature. When the mold works at high temperature for a long time, the hardness, strength and wear resistance of the mold will be reduced, and the mold surface will be more prone to wear, scratches and even cracks, shortening the service life of the mold; and, when blowing air to cool the plastic after plastic extrusion molding, it is impossible to quickly blow air to cool the extruded plastic in the first time.

[0018] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] The plastic extrusion molding equipment extrude and mold the dissolved plastic and reduce the waste of resources. However, the existing mold is prone to work in a high-temperature state for a long time during the plastic extrusion molding. This is because when the high-temperature plastic melt enters the mold cavity, it will directly contact the mold wall, and the heat will be quickly transferred from the melt to the mold, causing the mold temperature to rise, causing the mold to deform, thereby shortening the service life of the mold. For this reason, the present invention provides a processing equipment and a rotating mold assembly for molding recycled plastics, including a workbench 1, a rotating mold structure 2 is fixedly connected to the surface of the workbench 1, a heating structure 3 is arranged on the side of the rotating mold structure 2, and the heating structure 3 is fixedly connected to the surface of the workbench 1, and a plastic molding device 4 and two heat dissipation structures 5 are respectively arranged inside the rotating mold structure 2, and the two heat dissipation structures 5 are arranged at the front and rear ends of the plastic molding device 4.

[0020] When the plastic is being molded, the plastic molding device 4 is gathered inward for extrusion molding, and at the same time, the two heat dissipation structures 5 are driven to expand toward the rotating mold structure 2 to blow air to the sides of the plastic molding device 4 for heat dissipation. At the same time, the heat dissipation structures 5 can limit and stabilize the plastic molding device 4.

[0021] After the plastic is formed, when it moves outward through the plastic forming device 4, it drives the two heat dissipation structures 5 to gather inward to blow air to dissipate the formed plastic, and at the same time, the heat dissipation structures 5 are sealed and cooled.

[0022] The present invention takes into account that in the existing plastic extrusion molding process, the mold will generate a lot of high temperature. When the mold is working at high temperature for a long time, the hardness, strength and wear resistance of the mold will be reduced, and the mold surface will be more prone to wear, scratches and even cracks, shortening the service life of the mold. Therefore, when the plastic molding equipment 4 is gathered inward to extrude the plastic to form, the two heat dissipation structures 5 can be driven to swing outward, so that the heat dissipation structure 5 blows air to the outside of the mold to dissipate heat, and after the heat dissipation structure 5 is swung outward, it can fit with the rotating mold structure 2, so that the heat dissipation structure 5 is more stable during the heat dissipation, and can also limit the shaking phenomenon of the plastic molding equipment 4, thereby improving the stability of the plastic molding equipment 4 during plastic extrusion molding, and can also reduce the mold working in a high temperature state for a long time.

[0023] Furthermore, considering that the existing method of blowing air to cool the plastic after extrusion molding is unable to quickly blow air to cool the plastic after extrusion molding in the first place, if the plastic after extrusion molding is not blown to cool in time, the plastic after extrusion molding may become skewed or change in size, resulting in the inability to use the extruded plastic normally, thereby affecting the processing or use of the plastic after molding. Therefore, when the plastic molding device 4 moves away from the outside, it drives the two heat dissipation structures 5 to gather inward, so that the heat dissipation structure 5 is tilted to blow air to dissipate the plastic after extrusion molding by the plastic molding device 4, and when the two heat dissipation structures 5 gather inward, the plastic molding device 4 and the heat dissipation structure 5 can form a closed space, thereby improving the heat dissipation effect of the heat dissipation structure 5 on the plastic after extrusion molding by the plastic molding device 4, so that the plastic just extruded by the plastic molding device 4 can be blown to cool in the first place, thereby reducing the skewness phenomenon after extrusion molding.

[0024] First of all, in order to realize the mold rotation, in the continuous production process, in order not to interrupt the production process, it may be necessary to quickly change the mold. Therefore, through the mold rotation operation, you can quickly switch to another set of molds, thereby improving the overall efficiency of the production line. Then, the following specific structure needs to be disclosed in detail to realize the mold rotation function. Please refer to Figure 2-Figure 7 The mold rotation structure 2 at least includes a box body 21, which is fixedly connected to the surface of the workbench 1. The interior of the box body 21 is through-set. A driving structure 22 is set at the bottom of the workbench 1. The driving structure 22 is divided into a motor and a belt drive. A second bevel gear 24 is rotatably connected to the bottom of the workbench 1. The surface of the second bevel gear 24 is meshingly connected to the first bevel gear 23. The first bevel gear 23 is splined to the plastic molding equipment 4. When the mold needs to be rotated, the staff starts the motor to rotate the second bevel gear 24 and synchronously drive the first bevel gear 23 to rotate. Then the rotation of the first bevel gear 23 can drive the plastic molding equipment 4 to rotate, so that the mold of the plastic molding equipment 4 rotates, thereby realizing the mold rotation function.

[0025] In addition, in order to realize the dissolution of the plastic and guide it into the plastic molding device 4 for subsequent extrusion molding, the following specific structure needs to be disclosed in detail, please refer to Figure 1-Figure 4 The heating structure 3 includes a storage box 31, which is fixedly connected to the surface of the workbench 1. A guide tube 33 is fixedly connected to the bottom of the storage box 31. A heating element 32 is arranged on the outer ring surface of the guide tube 33. The staff puts the plastic into the storage box 31, and then the plastic enters the guide tube 33. The heating element 32 is started to heat the plastic guided inside the guide tube 33, so that the plastic is heated and dissolved. The dissolved plastic is guided to the inside of the box body 21, which is convenient for the subsequent extrusion molding of the dissolved plastic.

[0026] The present invention has the following improvements: To achieve extrusion molding of dissolved plastic, because plastic is usually solid at room temperature, it is not convenient to extrude and mold, so heating can make the plastic more fluid, so it is easier to extrude and mold, which helps to improve production efficiency and the quality of finished products, and then need to disclose the plastic molding equipment in detail 4, please refer to Figure 5-Figure 7 The plastic molding equipment 4 at least includes a first cylinder 41, which is fixedly connected to the outer ring surface of the box body 21, and the output end of the first cylinder 41 is fixedly connected to a first output shaft 42, which penetrates and is rotatably connected to the inside of the box body 21, and the end of the first output shaft 42 away from the first cylinder 41 is fixedly connected to a right mold 43, the inside of the right mold 43 is through-set, and a hose 46 is fixedly connected to the side of the right mold 43, and the end of the hose 46 away from the right mold 43 is through-fixedly connected to the box body 21.

[0027] The plastic molding device 4 at least includes a second cylinder 47, which is fixedly connected to the outer ring surface of the box body 21, and the output end of the second cylinder 47 is fixedly connected to the second output shaft 44, and the end of the second output shaft 44 away from the second cylinder 47 is fixedly connected to the left mold 45, and the outer ring surface of the second output shaft 44 is splined with the first bevel gear 23. When the dissolved plastic is directed to the inside of the box body 21, the dissolved plastic will continue to be directed from the hose 46 to the inside of the right mold 43, and then the staff will start the first cylinder 41 and the second cylinder 47 respectively, so that the first output shaft 42 and the left mold 45 are respectively moved inwardly, and the right mold 43 and the left mold 45 are synchronously driven to move inwardly, and considering that the hose 46 will grow when the right mold 43 moves, the hose 46 does not affect the hose 46 from guiding the dissolved plastic into the inside of the right mold 43 when the right mold 43 moves, and then the right mold 43 and the left mold 45 will fit each other after moving inwardly (please refer to Fig.10 Fig.11), so that the hose 46 guides the dissolved plastic to leak out from the raised part of the right mold 43, and then the recessed position of the left mold 45 is set, so that the right mold 43 and the left mold 45 cooperate with each other to realize the extrusion molding of the dissolved plastic.

[0028] Next, it is necessary to realize that the plastic molding device 4 will generate high temperature when working for a long time. If it works in a high temperature state for a long time, the service life of the right mold 43 and the left mold 45 will be reduced. As for why the right mold 43 and the left mold 45 are in a high temperature state, it is because when the dissolved plastic is guided to the right mold 43 and the left mold 45 for extrusion, the plastic is in a high temperature state, which will transfer the temperature to the right mold 43 and the left mold 45. Therefore, the following heat dissipation structure 5 needs to be disclosed in detail to reduce the right mold 43 and the left mold 45 from working in a high temperature state for a long time. Please refer to Figure 8-Figure 11 The heat dissipation structure 5 comprises at least two limit shafts 51, which are rotatably connected to the surface of the workbench 1, and two telescopic plates 52 are fixedly connected to the outer ring surfaces of the two limit shafts 51 respectively. A plurality of fans 53 are arranged inside the two telescopic plates 52, and two pins 54 are rotatably connected to the side of the two telescopic plates 52 away from the limit shafts 51 respectively. Two swing plates 55 are fixedly connected to the tops of the two limit shafts 51. When the right mold 43 and the left mold 45 gather inward to extrude the plastic, the surfaces of the right mold 43 and the left mold 45 will squeeze the outer ring surfaces of the two telescopic plates 52 respectively, so that the two telescopic plates 52 drive the two limit shafts 51 to swing respectively, that is, from a V-shape to a parallel state. Then, after the swinging ends, the staff will start the plurality of fans 53, so that the wind blown out by the fans 53 will be diverted to the outer ring surfaces of the right mold 43 and the left mold 45 for heat dissipation, thereby reducing the right mold 43 and the left mold 45 always working in a high temperature state and improving the service life of the right mold 43 and the left mold 45.

[0029] At this time, considering that the right mold 43 and the left mold 45 may shake when they gather inward to extrude the plastic, this is because the molds may wear out after long-term use, especially the wear of guide components such as guide pillars and guide sleeves will reduce the accuracy and increase the risk of shaking. Therefore, when the two telescopic plates 52 and the limit shaft 51 swing to the maximum distance, the ends of the two telescopic plates 52 close to the pin 54 will press against the sides of the right mold 43 and the left mold 45. At the same time, when the limit shaft 51 rotates, it will drive the two swing plates 55 fixed on the top to rotate, so that the two swing plates 55 are respectively against the inner wall of the box body 21, so that the two telescopic plates 52 can stabilize the stability of the telescopic plates 52 to maintain a parallel state after swinging.

[0030] In order to disclose the specific state and position of the plastic molding device 4 and the heat dissipation structure 5, it is convenient to understand the following working process and to dissipate the heat of the plastic after extrusion molding. Therefore, the following specific structure needs to be disclosed in detail. Please refer to Figure 8-Figure 11 When the right mold 43 and the left mold 45 are gathered inward, the two telescopic plates 52 are in a parallel state. When the right mold 43 and the left mold 45 are away from each other, the two telescopic plates 52 are in a V-shaped state. After the right mold 43 and the left mold 45 extrude the plastic and the right mold 43 and the left mold 45 move away from each other, the two telescopic plates 52 lose their blocking force, causing the two telescopic plates 52 to swing inward to form a V-shape, and then the wind blown by the fan 53 blows heat to the extruded surface of the right mold 43 and the left mold 45, and can also blow and cool the extruded plastic to prevent the plastic that has just been extruded from being in a high temperature state, making it inconvenient for the staff to take it out, thereby reducing injuries to the staff.

[0031] Furthermore, when the two telescopic plates 52 swing in a V-shape, the two limit shafts 51 can also rotate to drive the two swing plates 55 to swing, so that the swing plates 55 and the V-shaped telescopic plates 52 form a closed space (for details, please refer to Figure 2 ), thereby improving the effect of the right mold 43 and the left mold 45 being cooled by air blowing.

[0032] Two first bevel gears 23 and second bevel gears 24 are symmetrically arranged along the transverse center of the box body 21. The two second bevel gears 24 are splined to the outer annular surfaces of the first output shaft 42 and the second output shaft 44 respectively. The working process when mold rotation is required will be described in detail here. When the staff needs to rotate the mold, the staff starts the motor to make the belt drive move, and synchronously drives the two second bevel gears 24 to rotate, and drives the two second bevel gears 24 to rotate. Then the two second bevel gears 24 rotate to respectively drive the first output shaft 42 and the second output shaft 44 to rotate, so that the right mold 43 fixed by the first output shaft 42 and the left mold 45 fixed by the second output shaft 44 rotates, thereby realizing the mold rotation, which is convenient for the subsequent plastic extrusion molding.

[0033] Working principle: The staff puts the plastic into the storage box 31, and then the plastic enters the guide tube 33. Then, the heating element 32 is started to heat the plastic in the guide tube 33, and the plastic is heated and dissolved. Then, the dissolved plastic continues to flow from the hose 46 to the right mold 43. Then, the staff respectively starts the first cylinder 41 and the second cylinder 47, so that the first output shaft 42 and the left mold 45 move inward and fit each other (please refer to the details). Fig.10 Fig.11 ) to achieve extrusion molding of the dissolved plastic.

[0034] When the right mold 43 and the left mold 45 gather inward to extrude the plastic, the surfaces of the right mold 43 and the left mold 45 will squeeze the outer annular surfaces of the two telescopic plates 52 respectively, so that the two telescopic plates 52 respectively drive the two limit shafts 51 to swing, that is, from a V-shape to a parallel state. After the swinging ends, the staff will start multiple fans 53 so that the wind blown by the fans 53 will be diverted to the outer annular surfaces of the right mold 43 and the left mold 45 for heat dissipation, thereby reducing the right mold 43 and the left mold 45 always working in a high temperature state.

[0035] After the right mold 43 and the left mold 45 extrude the plastic, the first cylinder 41 and the second cylinder 47 are respectively activated to contract, so that the right mold 43 fixed by the first output shaft 42 and the left mold 45 fixed by the second output shaft 44 move away from each other. At this time, the two telescopic plates 52 lose their blocking force, so that the two telescopic plates 52 swing inward to form a V shape, and then the wind blown by the fan 53 blows and dissipates the heat on the surfaces of the right mold 43 and the left mold 45 extruded and formed. In addition, when the two telescopic plates 52 swing in a V shape, the two limit shafts 51 can also rotate to drive the two swinging plates 55 to swing, so that the swinging plates 55 and the V-shaped telescopic plates 52 form a closed space (for details, please refer to Figure 2 ), thereby improving the effect of the right mold 43 and the left mold 45 being cooled by air blowing.

[0036] When mold rotation is required, the staff starts the motor to make the belt drive move, and synchronously drives the two second bevel gears 24 to rotate, and then the two second bevel gears 24 rotate to respectively drive the first output shaft 42 and the second output shaft 44 to rotate, so that the right mold 43 fixed by the first output shaft 42 and the left mold 45 fixed by the second output shaft 44 rotate, thereby realizing the mold rotation, which is convenient for the subsequent plastic extrusion molding.

[0037] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.

The scope of protection of the present invention is defined by the attached claims and their equivalents.
