Description

Technical Field

[0001] The present application relates to the technical field of PP valves, and in particular to a PP valve blank processing device. Background Art

[0002] PP valve refers to a valve made of polypropylene (PP for short). It is a device used to control the flow of fluid (liquid or gas). PP material has excellent chemical stability, corrosion resistance and wear resistance, so it is often used to manufacture valves for various chemicals, acid and alkali solutions and corrosive media.

[0003] During the production process of PP valves, the blanks need to be filtered and screened to screen out excellent blank particles for melting and injection molding. Currently, most of the static filtration is performed by casting the PP material on an inclined and stationary filter screen. Under the action of gravity, the blank particles can be rolled along the filter screen for screening. Static filtration is to a certain extent limited by gravity and the rolling of particles. For small particles or higher screening requirements, high screening accuracy may not be achieved. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose a PP valve blank processing device to solve the problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model provides a PP valve blank processing device, including a device frame, a crushing box is fixedly installed on the top of the device frame, a crushing mechanism is arranged inside the crushing box, a fixing box is fixedly installed on the inner side of the device frame, a filter frame is arranged on the inner side of the fixed box, a filter screen is arranged inside the filter frame, a material guide plate is arranged at the bottom of the filter frame, a vibrator is arranged on the material guide plate, and an elastic vibration mechanism is arranged on the filter frame.

[0006] Preferably, the crushing mechanism includes a crushing roller rotatably connected to the inner wall of the crushing box, a motor is fixedly installed on the top of the device frame, and the output end of the motor is fixedly connected to the end of the crushing roller away from the crushing box. The crushing mechanism can disperse the PP material particles that are stuck together, which is convenient for subsequent screening and filtration.

[0007] Preferably, the elastic vibration mechanism comprises a bracket fixedly connected to the bottom of the inner wall of the fixed box, and a guide shaft is fixedly connected to the top of the bracket. The elastic vibration mechanism can make the filter frame vibrate back and forth during the process of filtering and screening material particles.

[0008] Preferably, the top of the guide shaft is fixedly connected to a limit plate, and a spring is movably sleeved on the outer surface of the guide shaft.

[0009] Preferably, the top of the spring is fixedly connected to a perforated seat, the top of the perforated seat is fixedly connected to the bottom of the filter frame, a soft rubber ring is provided inside the perforated seat, and the guide shaft passes through the soft rubber ring and enters the inner side of the perforated seat.

[0010] Preferably, a drawer is provided on the fixed box.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The PP valve blank processing device can make the filter screen in the filter frame vibrate repeatedly through the elastic vibration mechanism. In dynamic screening, the particles will be continuously affected by vibration or movement during the screening process, which makes the particles more likely to contact the screen. The particles will pass through the screen more easily under vibration or movement. At the same time, the particles will be more easily separated according to the size and shape of the particles under vibration or movement, which can effectively improve the screening accuracy.

[0013] 2. The PP valve blank processing device crushes and disperses the material particles through the crushing roller, effectively reducing the adhesion between the particles, making the subsequent filtering and screening easier. Compared with static filtration, this improved dynamic filtration and screening can more effectively screen out excellent blank particles and improve the screening accuracy.

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] See also Figure 1-4 A PP valve blank processing device includes a device frame 1, a crushing box 2 is fixedly installed on the top of the device frame 1, a crushing mechanism is arranged inside the crushing box 2, a fixing box 5 is fixedly installed on the inner side of the device frame 1, a filter frame 6 is arranged on the inner side of the fixing box 5, a filter screen 7 is arranged inside the filter frame 6, a material guide plate 8 is arranged at the bottom of the filter frame 6, a vibrator 9 is arranged on the material guide plate 8, and an elastic vibration mechanism is arranged on the filter frame 6.

[0021] Through the above technical solution, when the device is in use, the PP material particles are put into the crushing box 2, and the crushing mechanism is used to crush them to reduce the adhesion of the material particles. During the process of the material particles sliding and filtering on the filter screen 7 in the filter frame 6, the elastic vibration mechanism can make the filter screen 7 vibrate repeatedly to improve the filtering effect.

[0022] Specifically, the crushing mechanism includes a crushing roller 4 rotatably connected to the inner wall of the crushing box 2 , a motor 3 is fixedly installed on the top of the device frame 1 , and the output end of the motor 3 is fixedly connected to the end of the crushing roller 4 away from the crushing box 2 .

[0023] Through the above technical solution, the crushing roller 4 can crush and disperse the material particles during the rotation process, thereby reducing the adhesion of the material particles into agglomerates.

[0024] Specifically, the elastic vibration mechanism includes a bracket 11 fixedly connected to the bottom of the inner wall of the fixed box 5 , and a guide shaft 12 is fixedly connected to the top of the bracket 11 .

[0025] Through the above technical solution, the bracket 11 cooperates with the guide shaft 12 to relatively limit the spring 14, and the spring 14 can always be compressed and stretched back and forth in a relatively vertical reverse direction.

[0026] Specifically, the top of the guide shaft 12 is fixedly connected to a limit plate 13 , and a spring 14 is movably sleeved on the outer surface of the guide shaft 12 .

[0027] Through the above technical solution, the function of the limiting plate 13 is to prevent the opening seat 15 from being separated from the guide shaft 12 during the elastic vibration process.

[0028] Specifically, the top of the spring 14 is fixedly connected with the perforated seat 15 , the top of the perforated seat 15 is fixedly connected with the bottom of the filter frame 6 , and a soft rubber ring 16 is arranged inside the perforated seat 15 .

[0029] Through the above technical solution, the soft rubber ring 16 has a strong elastic deformation ability, which allows the opening seat 15 to perform a small-angle lateral micro-movement during the longitudinal movement.

[0030] Specifically, a drawer 10 is provided on the fixed box 5 .

[0031] Through the above technical solution, the drawer 10 is arranged below the material guide plate 8, and the screened material particles can be effectively collected.

[0032] Working principle: When the device processes the blank material of the PP valve, the material particles are first put into the crushing box 2, and the motor 3 is turned on to drive the crushing roller 4 to rotate. The crushing roller 4 can crush and disperse the material particles during the rotation process, effectively reducing the adhesion of the material particles into a block, which is convenient for subsequent filtering and screening. After the material particles are crushed in the crushing box 2, they will fall into the filter frame 6. Under the action of the gravity of the material particles, they will roll down along the inclined filter screen 7 for filtering and screening. In this process, the larger particles of PP valve blank material particles screened out can slide down and be collected directly, while the smaller blank material particles will be filtered and screened by the filter screen 7 and fall through the guide plate 8. The particles are put into the drawer 10 for collection and are subsequently processed in a unified manner. During this process, the vibrator 9 can be turned on to make the entire filter frame 6 vibrate continuously. During the vibration of the filter frame 6, the hole seat 15 will move up and down along the guide shaft 12 and compress the spring 14. The spring 14 forms a reverse elastic force after being compressed, which can act on the filter frame 6 through the hole seat 15 to accelerate the vibration of the filter screen 7 in the filter frame 6. The guide shaft 12 can make the filter frame 6 move laterally with a small amplitude when passing through the soft rubber ring 16 and cooperating with the hole seat 15 to vibrate, so that the entire inclined filter screen 7 vibrates back and forth in the process of filtering material particles, making the screening process more efficient.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
