Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe processing, in particular to a pipe processing feeding structure. Background Art

[0002] Substandard plastic pipe fittings typically refer to plastic pipes that fail to meet usage requirements due to quality issues during production, processing, and use. Plastic, as a critical chemical raw material, consumes significant resources during its production and processing. Recycling substandard plastic pipe fittings can convert them into renewable resources, conserving and recycling them. Recycled plastic waste undergoes crushing, cleaning, and granulation to produce recycled plastic pellets for use in the production of new plastic products. To ensure a stable and continuous flow of substandard plastic pipe fittings into the recycling system, a feed mechanism is required.

[0003] After searching, the patent with patent announcement number CN207684450U discloses a pipe processing feeding structure. Although the device is set to tilt the storage part to allow the pipe to slide naturally down to the limiting plate when in use, the dividing teeth on the limiting plate ensure that the pipes are conveyed one by one. The motor drives the connecting rod mechanism to swing the limiting plate and the rotating plate, so that the pipes are transported from the storage part to the conveying mechanism in an orderly manner. At the same time, the swing of the rotating plate assists the pipes to enter the conveying mechanism, realizing a stable and efficient feeding process. However, when in use, the device is only suitable for assembly line-type automatic unloading processes and cannot adapt to diverse production needs. For example, in some production scenarios, it may be necessary to transfer pipes from one place to another for loading, and this structure cannot directly realize this function, resulting in limited production processes. Since it is impossible to directly transfer and load pipes, manufacturers may need to arrange more manpower or time to manually complete this link, thereby reducing overall production efficiency. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a pipe processing feeding structure, which solves the problems raised in the background art.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A pipe processing feeding structure includes a column, a connecting rod is installed on the column, and a pneumatic clamp is installed on the connecting rod. The pneumatic clamp clamps and fixes the plastic pipe, and the plastic pipe is loaded and unloaded through the pneumatic clamp;

[0007] A second bevel gear is mounted on the column, a flange is mounted on the bottom end of the column, a connecting seat is mounted on the column, and a connecting rod is mounted on the end of the connecting seat away from the column;

[0008] A first bevel gear is installed at the end of the connecting rod facing away from the pneumatic clamp, and a first shaft sleeve and a second shaft sleeve are respectively provided at both ends of the connecting seat, and the first shaft sleeve and the second shaft sleeve are respectively movably sleeved on the column and the connecting rod, and a worm gear is provided at the bottom end of the first shaft sleeve, and the first shaft sleeve is connected to the motor transmission through the worm gear.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, a pad is installed at the bottom end of the motor, and the motor is supported by the pad.

[0011] The beneficial effects of adopting the above further scheme are:

[0012] When the motor is in direct contact with the support surface, vibration and long-term operation may cause wear and tear on the motor base or support surface. The use of spacers can act as a buffer, reducing direct contact and friction between the motor and the support surface, thereby protecting the motor and support surface from damage and extending their service life.

[0013] Furthermore, a reducer is installed at the output end of the motor, a worm is installed at one end of the reducer away from the motor, and the motor is connected to the worm gear through the reducer and the worm.

[0014] The beneficial effects of adopting the above further scheme are:

[0015] When a motor operates at normal speed, its output torque may be relatively low. By adding a speed reducer, the motor's speed can be reduced, correspondingly increasing the output torque. This allows the equipment to output greater torque at the same power, thereby improving the efficiency and processing capacity of the mechanical equipment. Worm and worm gear transmissions are characterized by a large transmission ratio and smooth transmission. The speed reducer and the transmission connection between the worm and worm gear further improve the transmission accuracy and stability, ensuring the accuracy and reliability of the equipment during the processing. Worm gear transmissions are self-locking, achieving reverse self-locking when the lead angle of the worm is less than the equivalent friction angle between the gear teeth.

[0016] Furthermore, the first sleeve is driven to rotate by a worm gear driven by a motor.

[0017] The beneficial effects of adopting the above further scheme are:

[0018] The motor, serving as the power source, transmits power to the worm gear through a transmission device such as a reducer. The worm gear then drives the entire system. This design achieves efficient power transmission, reduces energy loss during transmission, and improves overall system efficiency. The motor drives the worm gear, enabling precise rotational control. By adjusting the motor's speed and direction, the worm gear's rotational speed and direction can be precisely controlled to meet diverse processing requirements.

[0019] Furthermore, a boss is provided on the column, and the first sleeve is supported on the column via the boss.

[0020] The beneficial effects of adopting the above further scheme are:

[0021] The boss design provides a stable support platform for the first sleeve. This design can increase the contact area between the column and the first sleeve, disperse the load borne by the sleeve, and thus enhance the stability and rigidity of the entire structure.

[0022] Furthermore, the first bevel gear and the second bevel gear are engaged for transmission. When the worm gear rotates, the worm gear drives the connecting seat and the second sleeve to rotate with the column as the center, thereby causing the connecting rod inserted in the second sleeve to rotate around the column, and when the connecting rod rotates, it is driven to flip through the engagement of the first bevel gear and the second bevel gear.

[0023] The beneficial effects of adopting the above further scheme are:

[0024] Bevel gear transmission enables various transmission ratios. By adjusting the tooth ratio of the first and second bevel gears, the transmission ratio can be flexibly adjusted to meet different operating requirements. The large meshing area and stable meshing pattern of bevel gears ensure stable and reliable power transmission. The meshing transmission of bevel gears enables complex turning movements of the connecting rod around the column. The high transmission precision of bevel gears ensures accurate positioning of the connecting rod during turning, improving processing or operation accuracy.

[0025] The utility model provides a pipe processing feeding structure, which has the following beneficial effects:

[0026] Through the transmission system of motor, reducer, worm and worm gear, automatic rotation control of connecting rod and pneumatic clamp is realized, so that the loading and unloading operations of plastic pipes can be carried out automatically, which greatly improves production efficiency and reduces manual intervention.

[0027] The design adopts bevel gear transmission (first bevel gear and second bevel gear) and worm gear transmission (worm and worm wheel). This design makes the structure compact, the transmission efficiency high, and can achieve precise rotation control, so that the pneumatic gripper can flexibly perform clamping and rotation operations.

[0028] The boss on the column provides stable support for the first sleeve. At the same time, the connecting seat is respectively mounted on the column and the connecting rod through the first sleeve and the second sleeve. This design enhances the stability of the structure and ensures stability under high-speed rotation and heavy load. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1 to 4 As shown, the embodiment provided by the utility model:

[0039] Example 1

[0040] A pipe processing feeding structure includes a column 8, a connecting rod 1 is installed on the column 8, a pneumatic clamp 601 is installed on the connecting rod 1, the pneumatic clamp 601 clamps and fixes the plastic pipe 7, and the plastic pipe 7 is loaded and unloaded through the pneumatic clamp 601, a second bevel gear 5 is installed on the column 8, a flange 801 is installed at the bottom end of the column 8, a connecting seat 3 is installed on the column 8, and the connecting rod 1 is installed on the end of the connecting seat 3 facing away from the column 8.

[0041] Example 2

[0042] In order to facilitate the handling and flipping of pipes, for example, Figures 1 to 4As shown, the present invention also includes: a first bevel gear 2 is installed at the end of the connecting rod 1 facing away from the pneumatic clamp 601, and the first bevel gear 2 is meshed with the second bevel gear 5 for transmission. When the worm gear 3011 rotates, the worm gear 3011 drives the connecting seat 3 and the second shaft sleeve 302 to rotate with the column 8 as the center of the circle, thereby causing the connecting rod 1 inserted in the second shaft sleeve 302 to rotate around the column 8. When the connecting rod 1 rotates, the meshing of the first bevel gear 2 and the second bevel gear 5 drives the turning. The bevel gear transmission can achieve different transmission ratios. By adjusting the tooth ratio of the first bevel gear 2 and the second bevel gear 5, the transmission ratio can be flexibly adjusted to meet different working requirements. The bevel gears have a large meshing area and a stable meshing method, which can ensure the stability and reliability of power during transmission. Through the meshing transmission of the bevel gears, the complex turning movement of the connecting rod 1 around the column 8 can be achieved. The bevel gears offer high transmission precision, ensuring accurate positioning of the connecting rod 1 during the flipping process, improving processing or operational accuracy. A first sleeve 301 and a second sleeve 302 are provided at each end of the connecting base 3. These sleeves are movably mounted on the column 8 and the connecting rod 1, respectively. The column 8 is provided with a boss 802, through which the first sleeve 301 is supported and mounted on the column 8. The boss 802 provides a stable support platform for the first sleeve 301. This design increases the contact area between the column 8 and the first sleeve 301, dispersing the load borne by the sleeve, thereby enhancing the stability and rigidity of the entire structure. A worm gear 3011 is provided at the bottom end of the first sleeve 301. The first sleeve 301 is connected to the motor 4 via the worm gear 3011. The motor 4 drives the worm gear 3011 to rotate, driving the first sleeve 301. The motor 4, acting as the power source, transmits power to the worm gear 3011 via a transmission device such as a speed reducer 402. The worm gear 3011 then drives the entire system to rotate. This design achieves efficient power transmission, reduces energy loss during transmission, and improves the overall efficiency of the system. The motor 4 drives the worm gear 3011 to rotate, enabling precise rotation control. By adjusting the speed and direction of the motor 4, the rotation speed and direction of the worm gear 3011 can be precisely controlled to meet different processing requirements. A pad 403 is mounted at the bottom end of the motor 4, supporting the motor 4. When the motor 4 directly contacts the supporting surface, vibration and long-term operation may cause wear on the base or supporting surface of the motor 4. The use of pad 403 can act as a buffer, reducing direct contact and friction between motor 4 and the support surface, thereby protecting motor 4 and the support surface from damage and extending their service life. The output end of motor 4 is mounted with a reducer 402. The end of reducer 402 facing away from motor 4 is mounted with a worm 401. Motor 4 is connected to worm wheel 3011 through reducer 402 and worm 401. When motor 4 is running at normal speed, its output torque may be relatively small. By adding reducer 402, the speed of motor 4 can be reduced, and the output torque can be correspondingly increased.This enables the equipment to output greater torque at the same power, thereby improving the efficiency and processing capacity of the mechanical equipment. The worm gear transmission of worm 401 features a large transmission ratio and smooth transmission. The transmission connection between reducer 402, worm 401, and worm gear 3011 further improves transmission accuracy and stability, ensuring the accuracy and reliability of the equipment during processing. The worm gear transmission of worm 401 is self-locking, achieving reverse self-locking when the lead angle of worm 401 is less than the equivalent friction angle between the gear teeth.

[0043] Working principle:

[0044] The motor 4 serves as the power source for the entire system. Its output end is connected to a reducer 402, which reduces the rotational speed and increases the torque to ensure transmission stability and reliability. The output end of the reducer 402 is connected to a worm 401, which meshes with a worm wheel 3011 disposed at the bottom end of the first sleeve 301, forming a worm 401-worm gear transmission system. This transmission method has a large transmission ratio and self-locking properties, ensuring the accuracy and stability of rotation. The rotation of the worm wheel 3011 drives the connecting base 3 to rotate around the column 8, while the connecting rod 1, which is inserted into the second sleeve 302 on the connecting base 3, also rotates accordingly. The first bevel gear 2 mounted on the other end of the connecting rod 1 meshes with the second bevel gear 5 on the column 8, realizing a bevel gear transmission. This transmission method can convert the rotational motion of the worm wheel 3011-worm gear transmission into the up and down swinging motion and rotation of the connecting rod 1 at a specific angle.

[0045] The pneumatic gripper 601 mounted on the connecting rod 1 clamps and releases the plastic pipe 7 through a pneumatic control system. When the pneumatic gripper 601 receives a clamping signal, the pneumatic components inside it drive the gripper to close, tightly clamping the plastic pipe 7; when a release signal is received, the gripper opens, releasing the pipe. Driven by the motor 4, the connecting rod 1 drives the pneumatic gripper 601 to rotate around the column 8 to a specified position. When loading is required, the pneumatic gripper 601 clamps the plastic pipe 7 at the appropriate position and rotates with the connecting rod 1 to the processing area; when processing is completed, the pneumatic gripper 601 again clamps the processed pipe or new pipe and rotates to the unloading position for unloading.
