Description

Technical Field

[0001] This utility model relates to the field of screw unloading connector technology, and in particular to a rotary screw unloading connector. Background Technology

[0002] A screw is a tool that uses the physical and mathematical principles of inclined planes, circular rotation, and friction to gradually fasten objects and machine parts. After the screws are manufactured, a cutting fitting is needed to cut them into smaller parts.

[0003] Currently, traditional material feeding joints still have the following technical problems:

[0004] Firstly, traditional screw cutting connectors mostly use a straight cutting method, which is prone to jamming and accumulation, resulting in uneven cutting and affecting the production rhythm.

[0005] Secondly, during the unloading process, the friction between the screws and the conveyor channel, as well as the dust brought out by the screws themselves after production, will cause a lot of dust to be generated during the unloading process. This dust will not only pollute the production environment and affect the health of operators, but also easily accelerate the wear of the conveyor channel, reduce the service life of the conveyor channel, and also affect the cleanliness and quality of the screws. Utility Model Content

[0006] The purpose of this utility model is to provide a rotary screw feeding connector, which can improve the smoothness of the screw feeding process, avoid accumulation, and collect the dust generated during the feeding process, thereby effectively avoiding technical problems caused by dust.

[0007] The objective of this utility model is achieved through the following technical solution:

[0008] A rotary screw feeding connector includes a discharge pipe connected to a screw feeding port, an air duct disposed at the discharge end of the discharge pipe and having an inner diameter larger than the discharge pipe, an air inlet assembly disposed on the air duct, a spiral conveying pipe disposed at the bottom of the air duct, a collection box disposed at the discharge end of the spiral conveying pipe, a first filter screen horizontally disposed within the collection box, and a second filter screen disposed on the side wall of the collection box and located below the first filter screen; the discharge end of the spiral conveying pipe penetrates the top wall of the collection box and is located above the first filter screen; the mesh size of the first filter screen is larger than the mesh size of the second filter screen.

[0009] Preferably, the air intake assembly includes a plurality of air nozzles disposed on the top wall of the air duct, a first air pipe connected to the air intake end of each air nozzle, a second air pipe connected to the common air intake end of each of the first air pipes, and a fan disposed at the air intake end of the second air pipe.

[0010] Preferably, the spiral conveying pipe, the air duct, and the top wall of the collection box are rotatably connected.

[0011] Preferably, the outer wall of the spiral conveying pipe is fitted with a driven wheel, the outer wall of the air duct is provided with a motor base, the motor base is provided with a motor, and the output end of the motor is fitted with a driving wheel that meshes with the driven wheel.

[0012] Preferably, the side wall of the collection box is provided with a slot, and a first drawer is movably disposed in the slot, with the first filter screen being the bottom wall of the first drawer.

[0013] Preferably, the collection box is made of transparent material.

[0014] Preferably, a second drawer is provided inside the collection box and below the first drawer, and the second filter screen is provided above the second drawer.

[0015] Preferably, the outer wall of the second filter screen is provided with a connecting block, and the connecting block and the outer wall of the collection box are connected by bolts.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By replacing the existing linear conveying pipe with a spiral conveying pipe, the problems of easy jamming and inflexible conveying in traditional linear feeding can be effectively solved.

[0018] By installing an air duct, an air intake assembly, a first filter, a second filter, and a collection box, the gas generated by the air intake assembly during the screw feeding process can be discharged together with the screw from the spiral conveyor pipe into the collection box. This allows dust and fine debris adhering to the spiral conveyor pipe to enter the collection box. The dust then passes through the first filter into the lower part of the collection box, and is then trapped in the collection box by the second filter, preventing dust from being emitted into the environment and causing environmental pollution. At the same time, it also prevents dust from adhering to the inner wall of the spiral conveyor pipe, thus reducing the wear and tear on the spiral conveyor pipe. Attached Figure Description

Detailed Implementation

[0024] Example 1

[0025] A rotary screw feeder, such as Figure 1-3 As shown, the system includes a discharge pipe 1 connected to the screw discharge port, an air duct 2 located at the discharge end of the discharge pipe 1 with an inner diameter larger than that of the discharge pipe 1, an air inlet assembly located on the air duct 2, a spiral conveying pipe 3 located at the bottom of the air duct 2, a collection box 4 located at the discharge end of the spiral conveying pipe 3, a first filter screen 5 horizontally located inside the collection box 4, and a second filter screen 6 located on the side wall of the collection box 4 and below the first filter screen 5; the discharge end of the spiral conveying pipe 3 penetrates the top wall of the collection box 4 and is located above the first filter screen 5; the mesh size of the first filter screen 5 is larger than the mesh size of the second filter screen 6. Figure 1 As shown, the air duct 2 is fixed to the collection box 4 by a fixing rod 17. Further, as... Figure 2 As shown, the air intake assembly includes multiple air nozzles 7 disposed on the top wall of the air duct 2, a first air pipe 8 connected to the air intake end of each air nozzle 7, a second air pipe 9 connected to the common air intake end of each of the first air pipes 8, and a blower disposed at the air intake end of the second air pipe 9 (existing technology, not shown in the figure, but can be disposed on the collection box 4). In actual implementation, the first air pipe 8 is annular and disposed outside the discharge pipe 1.

[0026] Working principle: After production, the screws enter the discharge pipe 1 through the screw feeding port and then fall sequentially into the air duct 2 and the spiral conveyor pipe 3, finally being conveyed to the collection box 4 along the end of the spiral conveyor pipe 3. During the screw conveying process, the blower is turned on, supplying air to multiple air nozzles 7 through the second air pipe 9 and the first air pipe 8, so that the airflow from the air nozzles 7 forms a certain air pressure in the air duct 2, which can increase the conveying speed of the screws. At the same time, under the action of the airflow, dust and other particles in the spiral conveyor pipe 3 are also brought into the collection box 4. Because the first filter screen 5 has a large pore size, and under the action of the airflow, smaller dust particles will pass through the first filter screen 5 with the airflow and enter the lower part of the collection box 4. The dust is then filtered by the second filter screen 6 and retained in the collection box 4.

[0027] Through the synergistic effect of the above-mentioned devices, the conveying speed of the screws can be effectively improved, and the problems of screw jamming and accumulation can be avoided. At the same time, it can effectively prevent dust from being emitted into the environment and causing environmental pollution, and also prevent dust from adhering to the inner wall of the spiral conveying pipe 3, thus increasing the wear of the spiral conveying pipe 3.

[0028] Example 2

[0029] In Example 1, although the airflow increases the screw conveying speed, the lifting effect is limited. Therefore, based on Example 1, the spiral conveying pipe 3, the air duct 2, and the top wall of the collection box 4 are rotatably connected. Further, as... Figure 1 As shown, a driven wheel 10 is fitted onto the outer wall of the spiral conveying pipe 3, and a motor base 12 is provided on the outer wall of the air duct 2. A motor is mounted on the motor base 12, and a driving wheel 11 that meshes with the driven wheel 10 is fitted onto the output end of the motor. In specific implementation, during the feeding process, the motor is turned on, and under the action of the motor, the driving wheel 11 drives the driven wheel 10 to rotate, thereby driving the spiral conveying pipe 3 to rotate around its own axis, thus increasing the feeding speed of the screws.

[0030] Example 3

[0031] Based on Example 1 or Example 2, such as Figure 4 As shown, the collection box 4 is equipped with a first drawer 13. The first drawer 13 is slidably connected to first horizontal sliding grooves (existing technology, not shown in the figure) located on opposite sides of the collection box 4 to improve the smoothness of pulling out the first drawer 13 and to support the first drawer 13. The first filter screen 5 is the bottom wall of the first drawer 13. In this solution, by setting the first drawer 13, when a large number of screws are collected in the first drawer 13, the screws can be removed by pulling out the first drawer 13.

[0032] Furthermore, the collection box 4 is made of transparent material to facilitate observation of the amount of screws collected in the first drawer 13.

[0033] Furthermore, such as Figure 4As shown, a second drawer 14 is provided inside the collection box 4 and below the first drawer 13. The second filter screen 6 is located above the second drawer 14. The second drawer 14 is slidably connected to second horizontal sliding grooves (existing technology, not shown in the figure) provided on opposite sides inside the collection box 4 to improve the smoothness of pulling out the first drawer 13 and to support the first drawer 13. Furthermore, a connecting block 16 is provided on the outer wall of the second filter screen 6, and the connecting block 16 is connected to the outer wall of the collection box 4 by bolts 15. In this solution, by providing the second drawer 14, dust can be collected, and after the second drawer 14 is pulled out, it is also convenient to handle the dust, improving the convenience of operation. By providing the connecting block 16 and bolts 15, the second filter screen 6 and the collection box 4 are detachably connected, so that when a lot of dust adheres to the second filter screen 6, it is easy to disassemble and clean it.
