Description

Technical Field

[0001] The utility model relates to the technical field of PVC plastic pipes, in particular to a feeding device for manufacturing PVC plastic pipes. Background Technique

[0002] PVC plastic pipes are plastic pipes widely used in many fields such as construction, water supply and drainage, and chemical industry. They have good corrosion resistance, easy processability, economy, and a long service life. When producing PVC plastic pipes, PVC particles need to be fed into the hopper of an extruder. Through the rotation and heating of a screw, the PVC particles are melted and plasticized into a uniform melt. During the production, storage, or transportation of PVC particles, they may agglomerate, which will hinder the melting speed of the PVC particles, affect the production efficiency of PVC pipes, and may also increase the production cost of PVC pipes.

[0003] In view of the above problems, a feeding device for manufacturing PVC plastic pipes is now developed. Summary of the Utility Model

An inlet is provided on the feeding bucket, and a bucket cover is installed on the feeding bucket. A connecting rod is rotatably connected inside the feeding bucket. A driving assembly is installed on the right part of the feeding bucket. The driving assembly includes a protective frame, a driving motor, and two bevel gears. The protective frame is installed on the right part of the feeding bucket, the driving motor is installed on the protective frame, the driving motor output shaft is connected with the bevel gear, the upper part of the connecting rod is connected with the other bevel gear, the two bevel gears are meshed with each other, the lower part of the connecting rod is connected with an auger, a filtering assembly is installed at the lower part inside the feeding bucket. The filtering assembly includes a connecting ring. The connecting ring is connected to the lower part inside the feeding bucket, and a filter screen is connected to the connecting ring.

[0006] Optionally, the crushing and scraping mechanism includes mounting columns. Four mounting columns are connected to the connecting rod. Crushing components are arranged at the lower parts of the mounting columns. A scraping plate is connected between the outer sides of the mounting columns. The scraping plate is slidably connected with the connecting ring.

[0007] Optionally, a shock absorption mechanism is further included. The shock absorption mechanism includes a damper. The lower part of the feeding bucket is connected with the damper.

[0011] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:

[0012] The present utility model screens large - particle PVC particles through a filter screen, and then uses a driving component to drive a crushing component to crush the agglomerated PVC particles, while driving a scraper to scrape off the particulate matter remaining on the inner wall of the feeding bucket. The crushed PVC particles can save the melting cost and time, so as to accelerate the melting speed and efficiency of the PVC particles, thereby ensuring the normal operation of the production of PVC plastic pipes.

Detailed Embodiments

[0018] The following describes the embodiments of the present utility model with reference to the drawings.

[0019] A feeding device for manufacturing PVC plastic pipes, as Figures 1 - 3As shown in the figure, it includes a feeding bucket 1. There is a discharge port at the lower part of the feeding bucket 1. The lower part of the feeding bucket 1 is an inclined surface structure for facilitating discharging. An inlet 2 is provided on the feeding bucket 1. The inlet 2 is a threaded structure for facilitating connection with a conveying pipe. A bucket cover 3 is installed on the feeding bucket 1. A connecting rod 5 is rotatably connected inside the feeding bucket 1. A driving assembly 4 is installed on the right part of the feeding bucket 1. The driving assembly 4 includes a protective frame, a driving motor and two bevel gears. A protective frame is installed on the right part of the feeding bucket 1. A driving motor is installed on the protective frame. A bevel gear is connected to the output shaft of the driving motor. Another bevel gear is connected to the upper part of the connecting rod 5. The two bevel gears are meshed with each other. A screw conveyor 6 is connected to the lower part of the connecting rod 5. A filtering assembly 7 is installed at the lower inner part of the feeding bucket 1. The filtering assembly 7 includes a connecting ring 71. The connecting ring 71 is connected to the lower inner part of the feeding bucket 1. A filter screen 72 is connected to the connecting ring 71. A crushing and scraping mechanism 8 is arranged on the connecting rod 5.

[0020] As Figures 1 - 3 shown, the crushing and scraping mechanism 8 includes a mounting post 81. Four mounting posts 81 are connected to the connecting rod 5. Crushing components 82 are arranged at the lower parts of the mounting posts 81. A scraping plate 83 is connected between the outer sides of the mounting posts 81. The scraping plate 83 is slidably connected to the connecting ring 71.

[0021] As Figure 1 and Figure 4 shown, it further includes a shock absorption mechanism 9. The shock absorption mechanism 9 includes dampers 92. The dampers 92 are connected to the lower part of the feeding bucket 1. There are four dampers 92 in total. Buffer springs 93 are connected inside the dampers 92. A base 91 is connected between the lower parts of the dampers 92.

[0022] It should be noted that PVC plastic pipes are plastic pipes widely used in many fields such as construction, water supply and drainage, and chemical industry. They have good corrosion resistance, easy processability, economy, and a long service life. When producing PVC plastic pipes, PVC particles need to be fed into the hopper of the extruder. Through the rotation and heating of the screw, the PVC particles are melted and plasticized into a uniform melt. During the production, storage, or transportation of PVC particles, they may agglomerate, which will hinder the melting speed of PVC particles, affect the production efficiency of PVC pipes, and thus require crushing and filtering treatment of PVC particles to help accelerate the melting speed of PVC particles. First, connect the feeding pipe to the feeding port 2. The threaded interface of the feeding port 2 facilitates the connection of the feeding pipe to the device. Then, inject PVC particles into the feeding bucket 1. The filter screen 72 screens the PVC particles. Small particle materials enter the lower part of the feeding bucket 1 and quickly discharge through the inclined surface structure of the discharge port. Large particle materials will remain on the filter screen 72. At the same time, turn on the driving component 4. The rotation of the output shaft of the driving motor will drive the bevel gear on the right to rotate, and then drive the bevel gear on the left to rotate, thereby causing the connecting rod 5 to rotate. The rotation of the connecting rod 5 will drive the crushing component 82 to rotate. The crushing component 82 will crush the large particle materials remaining on the filter screen 72. The crushed PVC particles can save the melting cost and time to accelerate the melting speed and efficiency of PVC particles, thus ensuring the normal operation of PVC plastic pipe production. At the same time, the rotation of the connecting rod 5 drives the mounting column 81 to rotate, and then drives the scraper 83 to move. The scraper 83 will scrape off the particulate matter remaining on the inner wall of the feeding bucket 1. To prevent the discharge port from being blocked, the rotation of the connecting rod 5 will drive the auger 6 to rotate, which can prevent the crushed particles from blocking the device. The discharge port at the lower part of the feeding bucket 1 is of an inclined surface structure, which can quickly discharge the materials and further prevent the materials from being blocked. During the operation of the device, vibrations will occur. Under the action of the damper 92 and the buffer spring 93, the vibrations during the operation of the device can be reduced, thereby improving the stability of the entire device.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
