Technical Field

[0001] This invention relates to the field of polypropylene granulation production technology, specifically to a self-unloading dump truck for receiving and inspecting granules during the polypropylene extrusion granulation production process. Background Technology

[0002] Polypropylene is a thermoplastic resin obtained by polymerizing propylene. It is a non-toxic, odorless, tasteless, milky white, highly crystalline polymer. In the polypropylene granulation process, it is necessary to receive the granules produced during processing. Generally, the granules are directly introduced into a collection device for storage. However, this means that the collection device needs to be removed after storage, and directly introducing the granules into the collection device is not convenient for inspecting the granules. Summary of the Invention

[0003] The purpose of this invention is to provide a self-unloading bucket truck for receiving and inspecting granules during the polypropylene extrusion granulation production process, in order to solve the problems mentioned in the background art, which involve directly introducing the granules generated during processing into a collection device for storage. This would require removing the collection device after storage, and directly introducing the granules generated during processing into the collection device would also make it inconvenient to inspect the granules generated during processing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a self-unloading bucket truck for receiving and inspecting granules during the polypropylene extrusion granulation production process, comprising: a movable frame for moving in the working area, wherein the movable frame is provided with a hopper for receiving materials and capable of being overturned for unloading.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figure 1 and Figure 2 A self-unloading bucket truck for receiving, picking up, and inspecting polypropylene extrusion granulation during production includes: a movable frame 1 and a hopper 3. The movable frame 1 consists of a frame body and pulleys installed at the bottom of the frame body, allowing the movable frame 1 to move within the working area by sliding on the pulleys. Bushings 2 are provided on both the left and right sides of the movable frame 1, and rotating shafts 6 are provided on both the left and right sides of the hopper 3. The end of the rotating shaft 6 away from the hopper 3 is inserted into the bushing 2. The rotating shaft 6 rotates within the bushing 2, causing the hopper 3 to rotate around the bushing 2, thus achieving the flipping of the hopper 3. A handle 4 is provided on the hopper 3, and a pin sleeve 7 is provided on the right side of the hopper 3. A mounting block is provided on the movable frame 1, with an opening in which a pin 5 is inserted. The pin 5 can move left and right (and can also rotate within the opening). The pin 5 is used to fix the hopper 3 by inserting it into the pin sleeve 7.

[0028] It should be noted that the pin sleeve 7 can also be installed on the left side of the hopper 3; when the pin sleeve 7 is located on the left side of the hopper 3, the positions of the mounting block and the pin 5 also change accordingly, and the pin 5 corresponds to the pin sleeve 7; in order to fix the moving frame 1 and prevent it from moving automatically, a brake pad is installed on the pulley to fix the moving frame 1.

[0029] Please see Figure 1 The bushing 2 is equipped with a driving component (such as a motor), and the output shaft of the driving component is connected to the rotating shaft 6.

[0030] Working principle: Push the moving frame 1 to move the hopper 3 below the discharge pipe of the polypropylene granulator. The hopper 3 receives the material discharged from the discharge pipe. After receiving the material, push the moving frame 1 to move the hopper to the predetermined area. Move the pin 5 out of the pin sleeve 7 to release the restriction on the hopper 3. The operator holds the handle 4 and applies pressure to make the hopper 3 rotate around the shaft 6 (according to...). Figure 1 , Figure 2 As shown, hopper 3 can rotate forward or backward to tilt it down and discharge the material. At the same time, the drive unit can be activated (power is turned on) to make the rotating shaft 6 rotate automatically with hopper 3, so that hopper 3 can be tilted down automatically for unloading. After the material is discharged from hopper 3, it can be inspected.

[0031] In this embodiment, as a further optimization, please refer to... Figure 3 The outer wall of the pin 5 is provided with an external thread, and the inner wall of the pin sleeve 7 is provided with an internal thread. The internal thread matches the external thread. By using the matching of the external thread and the internal thread, the pin 5 is fixed in the pin sleeve 7, so that it will not automatically move out of the pin sleeve 7, thus ensuring the stability of the pin 5 in fixing the hopper 3.

[0032] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5 A bracket 8 is installed on the side of the bushing 2 away from the hopper 3 (only one bushing 2 has a bracket 8 installed, according to...). Figure 1 , Figure 2 The direction shown refers to the right bushing 2). A touch switch is installed on the side of the bracket 8 facing the bushing 2. The touch switch is electrically connected to the power supply of the drive unit through a wire. After the pin 5 is removed from the pin sleeve 7, the pin 5 is moved again to further increase the distance between it and the hopper 3. During this process, the pin 5 will press the touch switch to power on the drive unit, so that when the restriction on the hopper 3 is lifted, the drive unit can be controlled to automatically rotate the hopper 3.

[0033] In this embodiment, as a further optimization, please refer to... Figure 4 and Figure 5The pin 5 is equipped with a connector 9 (L-shaped), and the side wall of the hopper 3 is equipped with a push block 10. During the rotation of the hopper 3, the push block 10 will also move along with it and contact the connector 9 to press it, so that it moves the pin 5 to press the touch switch. When the operator removes the pin 5 from the pin sleeve 7, but does not press the touch switch (at this time the drive unit is not working), the hopper 3 will not flip. When the operator holds the handle 4 and rotates the hopper 3, the push block 10 can move the pin 5 again to press the touch switch, so that the drive unit is energized and works, so that the hopper 3 can still flip automatically (that is, when the operator directly flips the hopper 3, the drive unit can actively assist the hopper 3 to rotate).

[0034] It should be noted that no return spring is installed between pin 5 and the mounting block, so the pin will not automatically return to its original position after it moves.

[0035] In this embodiment, as a further optimization, please refer to... Figure 5 The bushing 2 includes a support block 21 mounted on the movable frame 1 and a bushing body 22. The bushing body 22 is detachable from the support block 21 (the bushing body 22 is mounted on the support block 21 by bolts). The rotating shaft 6 is inserted into the bushing body 22. When the connection between the bushing body 22 and the support block 21 is disconnected, the connection between the movable frame 1 and the hopper 3 can be disconnected, thereby allowing the hopper 3 to be removed.

[0036] Example 2

[0037] As a further optimization of Example 1, please refer to Figure 6 and Figure 8 Guide plates 11 are hinged to the top of both sides of the inner cavity of the hopper 3. The bottom of the guide plates 11 fits against the bottom of the inner cavity of the hopper 3. The two guide plates 11 are located on the front and rear sides of the inner cavity of the hopper 3 respectively (according to...). Figure 1 , Figure 2 (as shown in the direction), a connecting rope 12 is installed between the two guide plates 11 (according to...) Figure 1 , Figure 2 As shown, a connecting rope 12 is installed on the rear side of the rear guide plate 11. One end of the connecting rope 12, away from the rear guide plate 11, extends into the inner wall of the hopper 3 and then extends out to connect with the rear side wall of the front guide plate 11. When the hopper 3 tilts forward (according to...), Figure 1 , Figure 2 If the direction is reversed, the rear guide plate 11 moves upward and the front guide plate 11 rotates downward; under the action of gravity, the upper guide plate 11 rotates downward, pulling the connecting rope 12, causing the lower guide plate 11 to rotate upward, so that the inner ends of the two guide plates 11 come together to guide the material discharge from the hopper 3, and at the same time squeeze the material, so that the material in the hopper 3 is discharged faster.

[0038] In this embodiment, as a further optimization, please refer to... Figure 8 The hopper 3 is equipped with a drive mechanism 13 (which can be an electric telescopic rod). The moving end of the electric telescopic rod is in contact with the guide plate 11. The hopper 3 is equipped with a touch switch, which is electrically connected to the power supply of the electric telescopic rod and is located on the moving path of the guide plate 11. During the rotation of the guide plate 11, the touch switch will be pressed, which will energize the drive mechanism 13 to drive the guide plate 11 to rotate and support it, ensuring that the guide plate 11 can rotate.

[0039] In this embodiment, as a further optimization, please refer to... Figure 6 and Figure 7 The guide plate 11 includes a mounting plate 111. The bottom of the mounting plate 111 has a slot 112. A movable plate 113 is slidably inserted into the slot 112. An elastic element (spring) is installed between the slot 112 and the movable plate 113. When the guide plate 11 rotates so that the inner end of the guide plate 11 does not contact the inner wall of the hopper 3 (i.e., the bottom of the guide plate 11 does not contact the bottom of the inner cavity of the hopper 3), the movable plate 113 moves outward from the slot 112 through the expansion of the elastic element and continues to contact the inner wall of the hopper 3, so that there is no reduction in the distance between the guide plate 11 and the hopper 3, ensuring that the material inside the hopper 3 can be completely discharged.
