Abstract
Description
Technical Field
[0001] This utility model relates to the field of polypropylene pipe processing technology, specifically to a recycling device for waste polypropylene pipes. Background Technology
[0002] Polypropylene pipes are widely used in construction, municipal engineering, agricultural irrigation, and many other fields due to their advantages such as strong chemical corrosion resistance, light weight, and convenient installation. However, the processing of polypropylene pipes inevitably generates a large amount of waste. Taking extrusion molding as an example, in the initial stage of extrusion, the need for equipment parameter adjustments results in a large number of defective products. Equipment malfunctions and raw material fluctuations during pipe production also lead to waste.
[0003] Currently, the industry commonly uses recycling bins or containers near processing equipment to recycle waste polypropylene pipes. However, this traditional recycling method has significant drawbacks. The recycling bins have limited capacity, and once full, workers must replace them promptly. During continuous pipe processing, it's difficult for workers to spare the time to change bins; if not replaced in time, waste will overflow, causing clutter in the work area and potentially polluting the production equipment and surrounding environment. Furthermore, frequent bin changes disrupt the continuity of pipe processing, increasing labor intensity, reducing production efficiency, and raising production costs.
[0004] With the continuous growth of market demand for polypropylene pipes, the requirements for pipe production efficiency and quality are also increasing. Traditional recycling methods are no longer sufficient to meet the needs of modern production, and there is an urgent need for a more efficient and convenient waste polypropylene pipe recycling device to address the shortcomings of existing recycling methods.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a recycling device for waste polypropylene pipes, comprising a base, a turntable rotatably mounted on the base, and multiple recycling cylinders placed on the turntable for recycling waste pipes. The turntable has an open mounting groove at one end for installing the recycling cylinders. A roller is installed in the mounting groove, and a detachable baffle is installed at the opening of the mounting groove to block the recycling cylinders. In use, the recycling cylinders are switched by rotating the turntable.
[0009] Furthermore, the turntable has a slot for inserting a baffle.
[0010] Furthermore, a limiting block is provided at the top of the baffle, and a groove is formed on the limiting block.
[0011] Furthermore, a connecting frame is fixedly installed on the base, and an insertion rod is slidably installed on the connecting frame. The turntable has an insertion hole corresponding to the insertion rod, and the insertion rod and the insertion hole cooperate to position the recycling cylinder.
[0012] Furthermore, an outwardly protruding fixing block is provided on the outer wall of the top of the insertion rod, and a spring is provided between the fixing block and the connecting frame, the spring providing elastic force for the insertion rod to rebound.
[0013] Furthermore, a drive handle is provided at the bottom of the insertion rod.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, this utility model provides a recycling device for waste polypropylene pipes, which has the following beneficial effects:
[0016] This waste polypropylene pipe recycling device features a rotating turntable mounted on a base, with multiple recycling bins for collecting waste pipes. When a bin is full, simply rotating the turntable quickly switches to the next bin. This simple and convenient operation, compared to traditional methods, eliminates the need for manual handling and replacement of new bins, significantly saving time, greatly improving replacement efficiency, and ensuring the continuity of pipe processing.
[0017] Switching between recycling bins can be accomplished with just a simple turntable rotation, effectively reducing labor intensity and allowing workers to devote more energy to the pipe processing and production process. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Please see Figure 1-7 The present invention discloses a recycling device for waste polypropylene pipes, comprising a base 1, a turntable 2 rotatably mounted on the base 1, and multiple recycling cylinders 5 placed on the turntable 2 for recycling waste pipes. The turntable 2 has an installation groove 3 with one end open, which is used to install the recycling cylinders 5 to improve the stability of fixing the recycling cylinders 5.
[0028] The mounting slot 3 is equipped with a roller 4, which facilitates the installation and removal of the recycling cylinder 5. The recycling cylinder 5 can be easily moved by sliding along the roller 4, making it easier to remove and install the recycling cylinder 5 from the mounting slot 3, and making the operation more convenient.
[0029] A removable baffle 7 is installed at the opening of the mounting slot 3. The baffle 7 is installed at the opening of the mounting slot 3 to block the recycling cylinder 5 and prevent the recycling cylinder 5 from falling out of the mounting slot 3. The turntable 2 has a slot 6 for inserting the baffle 7. A limit block 8 is provided on the top of the baffle 7 to prevent the baffle 7 from falling out of the slot 6. The limit block 8 has a groove 9 to facilitate manual operation of the baffle 7. The baffle 7 can be installed by inserting and removing; it can also be installed by rotating, sliding, etc.
[0030] During use, the operator can switch the recycling cylinder 5 by rotating the turntable 2, which makes switching the recycling cylinder 5 easier and faster.
[0031] A connecting frame 10 is fixedly installed on the base 1, and an insertion rod 11 is slidably installed on the connecting frame 10. The turntable 2 has an insertion hole 12 corresponding to the insertion rod 11. The insertion rod 11 and the insertion hole 12 cooperate to position the recycling cylinder 5. After the turntable 2 rotates to the position, the insertion rod 11 is inserted into the insertion hole 12 to position the recycling cylinder 5.
[0032] A protruding fixing block 13 is provided on the outer wall of the top of the insertion rod 11. A spring 14 is provided between the fixing block 13 and the connecting frame 10. The spring 14 provides elastic force for the insertion rod 11 to rebound. A drive handle 15 is provided at the bottom of the insertion rod 11.
[0033] In summary, this waste polypropylene pipe recycling device allows the operator to process pipes without stopping the equipment when the current recycling bin 5 is nearly full. The operator simply holds the turntable 2 with both hands and slowly rotates it clockwise or counterclockwise. As the turntable 2 rotates, the next empty recycling bin 5 gradually moves to the user's work area until a precise connection is made, completing the switching of recycling bin 5. During the switching process, careful observation of the movement of the recycling bin 5 is necessary to ensure a smooth and stable placement.
