[0002] A vertical injection molding machine is a mechanical device that typically consists of an injection system, a mold clamping system, a hydraulic transmission system, an electrical control system, a lubrication system, a heating and cooling system, and a safety monitoring system. It is used to process plastics, and PET bottle caps are processed using a vertical injection molding machine.

[0003] Announcement No. CN217257926U proposes a novel vertical injection molding machine. A motor drives a synchronous pulley to rotate, causing a auger to rotate inside the outer tube for material feeding. This allows workers to feed the material from below, conveying plastic granules upwards, significantly improving feeding efficiency, eliminating the need for workers to climb to higher positions, and effectively enhancing feeding safety. Furthermore, the feeding mechanism can be moved using casters at the bottom of the support frame.

[0004] However, in the implementation of this device, the feeding mechanism is set on one side of the vertical injection molding machine to complete the feeding assembly, and the feeding mechanism is moved with pulleys and other structures. As a result, the feeding mechanism occupies a large space, and in use, the feeding mechanism needs to be moved to a suitable position to complete the feeding of the vertical injection molding machine, which is too cumbersome. Therefore, a vertical injection molding machine with a heating structure was proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a vertical injection molding machine with a heating structure, including a vertical injection molding machine body 1, a storage tank 3 fixedly connected to the surface of the vertical injection molding machine body 1, the interior of the storage tank 3 being inclined to collect incoming plastic particles, a feed hopper 4 fixedly connected to the surface of the storage tank 3, the feed hopper 4 also being inclined, a conveying pipe 5 fixedly connected to the interior of the storage tank 3, the conveying pipe 5 extending to the exterior of the storage tank 3, a discharge pipe 8 fixedly connected to the surface of the conveying pipe 5 on the exterior of the storage tank 3, a groove 13 formed on the surface of the conveying pipe 5 on the interior of the storage tank 3, an auger 16 rotatably connected to the interior of the conveying pipe 5, a motor 6 being provided at the upper end of the conveying pipe 5, the output end of the motor 6 extending into the interior of the conveying pipe 5, and the output end of the motor 6 being fixedly connected to the auger 16 via a coupling.

[0026] A protective shell 7 is fixedly connected to the upper end of the conveying pipe 5. The motor 6 is fixedly connected to the protective shell 7. The interior of the protective shell 7 is rotatably connected to the mounting shaft of the auger 16. A rotating rod 9 is rotatably connected inside the protective shell 7. A sprocket assembly 17 is provided on the surface of the rotating rod 9 and the mounting shaft of the auger 16. The sprocket assembly 17 is located inside the protective shell 7. The sprocket assembly 17 is set so that the auger 16 drives the sprocket assembly 17 to rotate when it rotates. In turn, the sprocket assembly 17 drives the rotating rod 9 to rotate. At the same time, the protective shell 7 covers and protects the sprocket assembly 17.

[0027] The surface of the vertical injection molding machine body 1 is provided with a heating shell 2, and a collection hopper 10 is fixedly connected to the surface of the heating shell 2. An extrusion structure is provided inside the heating shell 2. The PET bottle cap material entering is heated and melted through the heating shell 2. After the PET bottle cap material is melted, it is extruded and conveyed to the mold for processing. This has been disclosed in the comparative case, so it will not be explained again.

[0028] A screening screen 14 is fixedly connected inside the collecting hopper 10. The screening screen 14 is set at an inclination. By setting the screening screen 14, the PET bottle cap raw material particles that enter the heating shell 2 are screened, thereby preventing larger particles from entering the heating shell 2. This avoids the situation where the PET bottle cap raw material particles are too large and cannot be completely melted, thus avoiding the impact on subsequent processing.

[0029] A discharge pipe 11 is fixedly connected to the surface of the collecting hopper 10. The end of the discharge pipe 11 away from the collecting hopper 10 is fixedly connected to the storage box 3, and the discharge pipe 11 and the storage box 3 are interconnected. A fixed shell 12 is fixedly connected to the surface of the discharge pipe 11. A rotating rod 9 passes through the interior of the discharge pipe 11. The surface of the rotating rod 9 is rotatably connected to the interior of the discharge pipe 11. A crushing block 15 is fixedly connected to the end of the rotating rod 9 located inside the discharge pipe 11. The cross-section of the crushing block 15 is diamond-shaped. Both the surface of the crushing block 15 and the inner wall of the fixed shell 12 are provided with crushing protrusions.

[0030] Furthermore, to reduce material blockage in the screening screen 14, a vibration device can be installed on the screening screen 14. Since the vibration device is a known technology, it will not be explained in detail here.

[0031] Working principle: When PET bottle cap raw materials need to be supplied to the equipment, the operator puts the PET bottle cap raw materials into the storage box 3 through the feed hopper 4, and starts the motor 6 at the same time. The output end of the motor 6 drives the auger 16 to rotate. With the setting of the groove 13 and the inclined surface inside the storage box 3, the PET bottle cap raw materials enter the conveying pipe 5 and move inside the conveying pipe 5 under the rotation of the auger 16. As the auger 16 rotates, the PET bottle cap raw materials move upward. When the PET bottle cap raw materials reach the position of the discharge pipe 8, the PET bottle cap raw materials will enter the collection hopper 10 through the discharge pipe 8, completing the conveying of PET bottle cap raw materials.

[0032] As larger PET bottle cap raw materials enter the collection hopper 10, they slide down the inclined surface of the screening screen 14 into the outlet pipe 11. At the same time, when the auger 16 rotates, it drives the sprocket assembly 17 to rotate, which in turn drives the rotating rod 9 to rotate. The rotating rod 9 drives the crushing block 15 to rotate, and the PET bottle cap raw materials that have entered the outlet pipe 11 will enter the gap between the crushing block 15 and the fixed shell 12. With the help of the protrusions on the surface of the crushing block 15 and the inner wall of the fixed shell 12, the PET bottle cap raw material particles are crushed, so that the particles can finally return to the storage box 3 through the outlet pipe 11 for use. This avoids the need to remove and crush unqualified PET bottle cap raw materials later, making it easier for staff to use.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
