Description

Technical Field

[0001] This invention belongs to the field of waste barrel refurbishment technology, and in particular relates to a vertical barrel opening processing equipment and its processing technology. Background Technology

[0002] The refurbishment process after recycling used iron drums requires grinding the drum openings and applying anti-rust paint to the drum walls. Due to significant variations in diameter, height, and opening position among different manufacturers and models of used steel drums, the current processing method is manual. Manual processing has the following disadvantages: 1. All processes require manual handling, resulting in high labor intensity, operational difficulty, and high labor costs; 2. The processing requires close proximity to the workers, and the generated harmful substances can harm their health, posing a significant health risk; 3. To minimize the impact of harmful substances on human health, manual operation must be carried out in open areas, and the waste gases produced by the volatilization of harmful substances during processing directly enter the air, causing environmental damage.

[0017] Furthermore, the driving component includes a pair of driving wheels and a pair of auxiliary wheels. The driving wheels are located on one side of the top of the barrel. During processing, the driving wheels press against the side wall of the barrel, and the rotation of the driving wheels drives the barrel to rotate. The auxiliary wheels are symmetrically located on the other side of the barrel. The auxiliary wheels press against the side wall of the barrel and are used to cooperate with the driving wheels to realize the rotation of the barrel. The driving wheels are driven by a motor.

[0018] The driving component also includes a mounting bracket and a third drive. The mounting bracket is movably installed within the frame and has a U-shaped structure. The third drive is mounted on the frame, and its telescopic end is fixedly connected to the mounting bracket, for driving the mounting bracket to move toward or away from the barrel. The drive wheel and the auxiliary wheel are respectively rotatably mounted on the mounting bracket on both sides of the frame.

[0019] Furthermore, the frame is equipped with a bucket opening sensor and a bucket lid pressure roller sensor. During processing, the bucket opening sensor and the bucket lid pressure roller sensor are located above the bucket body. The bucket lid pressure roller sensor is used to detect the raised position of the bucket body. The bucket opening sensor is used to detect whether the bucket opening has been rotated to a specified position.

[0020] Furthermore, the grinding and cleaning component includes a frame, a rotating jaw, a grinding brush head, and a fourth driver.

[0022] This invention provides a process for processing the opening of a vertical barrel, comprising the following steps:

[0023] S1. After the barrel is flipped into a vertical position by the flipping device, it is sent into the feed end of the conveyor line.

[0024] S2. The barrel is transported to the processing station, and the barrel opening is polished using a polishing device.

[0025] S3. After the barrel mouth is polished, the barrel body continues to be conveyed to the rust prevention station via the conveyor line. The sealing device presses the top of the barrel body to seal it, and at the same time, rust prevention spraying is carried out on the inside of the barrel body from the bottom.

[0032] S25. After grinding is completed, the rotating chuck moves the barrel lid back to its original position or places it in the designated position. Then the lifting platform descends and the barrel is transported to the next station via the conveyor line.

[0033] Furthermore, after entering the processing station, the lid pressure roller sensor detects that the lid has risen to the predetermined height and sends a signal to the control system, which then controls the lifting platform to stop rising.

[0034] When the drive unit drives the barrel to rotate, the barrel opening sensor detects that the barrel opening has moved to a designated position and sends a signal to the control system, which then controls the drive unit to stop operating.

[0035] Compared with existing technologies, the vertical barrel mouth processing equipment and processing technology described in this invention have the following beneficial effects:

[0036] The vertical barrel opening processing equipment described in this invention replaces traditional manual processing with automated processing, greatly reducing the workload of workers, improving processing efficiency, and saving labor costs.

[0037] The vertical barrel opening processing equipment described in this invention eliminates the need for close-range operation by workers, avoiding the release of harmful substances that could harm the human body and ensuring the health of workers. Furthermore, the automated equipment can be used in enclosed factory buildings, allowing for unified treatment of waste and preventing the direct discharge of exhaust gases that could impact the environment.

[0038] In the vertical barrel mouth processing equipment described in this invention, the grinding device lifts the barrel body through a lifting platform and clamps the barrel body with upper and lower pressure rollers to adapt to the height of different barrel models.

Detailed Implementation

[0053] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0054] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0055] The present invention provides a vertical barrel mouth processing equipment, including a conveyor line 4, a processing station and a rust prevention station, wherein the rust prevention station is located on the discharge side of the processing station; the conveyor line 4 passes through the processing station and the rust prevention station; a grinding device 1 is provided in the processing station for grinding the barrel mouth.

[0056] A tilting device is installed at the feed end of conveyor line 4 to tilt the horizontally fed barrel 3 to a vertical position before feeding it into conveyor line 4. The tilting device is existing technology and will not be described in detail here. Specifically, conveyor line 4 adopts a chain conveyor.

[0057] The polishing device 1 includes a frame 11, a lifting platform 14, a polishing and cleaning component 16, a driving component 13, and a positioning component 15. The lifting platform 14 is installed at the bottom of the frame 11 to support the bottom of the bucket. The polishing and cleaning component 16 is installed at the top of the frame 11 to clean and polish the bucket opening. The driving component 13 is arranged on both sides of the iron bucket to drive the bucket body 3 to rotate. The positioning component 15 is installed at the top of the frame 11 to determine the position of the bucket opening. After positioning, the polishing and cleaning component 16 moves toward the positioning component 15. The position of the positioning component 15 is detected by the sensor at the front end of the polishing and cleaning component 16 to determine the position of the bucket opening. Then the positioning component 15 is moved away, and the polishing and cleaning component 16 is used to polish the bucket opening.

[0058] The frame 11 is equipped with a bucket mouth sensor and a bucket lid pressure roller sensor. During processing, the bucket mouth sensor and the bucket lid pressure roller sensor are located above the bucket body 3. The bucket lid pressure roller sensor is used to detect the raised position of the bucket body 3. The bucket mouth sensor is used to detect whether the bucket mouth has been rotated to a specified position.

[0059] The grinding and cleaning component 16 includes a frame 162, a rotating jaw 164, a grinding brush head 163, and a fourth driver 161. The frame 162 is movably mounted on the frame 11, and the fourth driver 161 is mounted on the frame 11. The driving end of the fourth driver 161 is fixedly connected to the frame 162 for driving the frame 162 to rise and fall. The grinding brush head 163 and the rotating jaw 164 are mounted at the bottom of the frame 162. A rotary motor is installed in the frame 162 for driving the grinding brush head 163, and a protective cover is provided on the outside of the grinding brush head 163. The rotating jaw 164 is driven by a jaw 155 cylinder for removing the bucket lid. A synchronous pulley is provided in the frame 162, and the top of the grinding brush head 163 and the rotating jaw 164 are connected by a synchronous pulley. During processing, the grinding and cleaning component 16 detects the position of the positioning component 15 through a front-end sensor to determine the position of the bucket opening. After determination, the positioning component 15 is moved away. The rotating jaw 164 moves above the bucket lid and removes the lid by clamping and rotating it. The polishing brush head 163 moves above the bucket opening and then polishes the opening. After polishing, according to the downstream process requirements, the rotating jaw 164 can be used to move the bucket lid back to its original position, or the bucket lid can be placed in a designated position. Specifically, the fourth actuator 161 is a lifting electric cylinder.

[0060] The lifting platform 14 includes a support plate 143 and a first driver 144. The support plate 143 is located at the bottom of the barrel 3 and is used to support the barrel 3. The first driver 144 is installed on the crossbeam at the bottom of the frame 11. The driving end of the first driver 144 is fixedly connected to the support plate 143 and is used to drive the support plate 143 to rise and fall. Several rectangular through holes are opened on the support plate 143 along the circumferential direction. A pressure roller 141 is rotatably installed in the rectangular through holes. During processing, the pressure roller 141 abuts against the bottom edge of the barrel 3. The surface of the pressure roller 141 needs to be covered with soft materials such as rubber or polyurethane to prevent the barrel 3 from leaving marks on the surface of the barrel 3 when it rotates. Several outer support rollers 142 are rotatably installed on the upper surface of the support plate 143 along the circumferential direction. During processing, the outer support rollers 142 abut against the inner wall of the barrel 3 to assist in limiting the barrel 3. When the barrel 3 is transferred to the processing position, the support plate 143 drives the barrel 3 to rise. After the barrel lid pressure roller sensor detects that the barrel lid is in place, it sends a signal to the driver to stop rising. Specifically, the first driver 144 is a servo electric cylinder.

[0061] The positioning component 15 comprises a top plate 152, a second driver 151, a lifting plate 156, a bottom plate 154, and a pair of claws 155. The top plate 152 is slidably mounted on the frame 11. The second driver 151 is mounted on the top plate 152, and the telescopic end of the bottom of the second driver 151 is fixedly connected to the lifting plate 156 for driving the lifting plate 156 to rise and fall. A crossbar is installed at the bottom of the lifting plate 156, and the bottom plate 154 is mounted on the crossbar through a top slider, thereby movably mounting the bottom plate 154 at the bottom of the lifting plate 156. The bottom plate 154 can move freely along the crossbar to accommodate errors in the position of the bucket opening. The claws 155 are symmetrically fixed in a V-shape at the bottom of the bottom plate 154 for determining the position of the bucket opening. The figure-eight gripper 155 can move slightly left and right along with the base plate 154. Due to the error in the position of the bucket opening, as the bucket opening moves from the larger end to the smaller end into the figure-eight gripper 155, the position of the figure-eight gripper 155 and the base plate 154 can be adjusted according to the error of the bucket opening. The upper sensor detects that the bucket opening is in position and stops the rotation of the bucket body 3. The positioning component 15 also includes a gripper limiting rod 153, which is fixedly installed at the bottom of the top plate 152. The lifting plate 156 has a through hole for the gripper limiting rod 153 to pass through, and the lifting plate 156 moves up and down along the gripper limiting rod 153. Before processing, the barrel opening rotates to a predetermined position. The barrel opening sensor detects the barrel opening's position and sends a feedback signal to the control system, causing the positioning component 15 to descend. The positioning component 15 is positioned a certain distance in front of the barrel opening. Subsequently, the drive component 13 drives the barrel body 3 to rotate, causing the barrel opening to engage with the clamping claw 155 from the wide end. The positioning component 15 positions the barrel opening. The grinding and cleaning component 16 detects the position of the positioning component 15 through its front-end sensor, thus determining the barrel opening position. During processing, the positioning component 15 moves away, and the grinding brush head 163 moves to the determined barrel opening position for grinding. Specifically, the second drive 151 is a downward pressure cylinder.

[0062] The driving component 13 includes a pair of driving wheels 134 and a pair of auxiliary wheels 133. The driving wheels 134 are located on one side of the top of the barrel 3. During processing, the driving wheels 134 press against the side wall of the barrel 3, and the rotation of the driving wheels 134 drives the barrel 3 to rotate. The auxiliary wheels 133 are symmetrically arranged on the other side of the barrel 3. The auxiliary wheels 133 press against the side wall of the barrel 3 and are used to cooperate with the driving wheels 134 to realize the rotation of the barrel 3. The driving wheels 134 are driven by a motor. The driving component 13 also includes a mounting frame 132 and a third driver 131. The mounting frame 132 is movably installed in the frame 11 and has a U-shaped structure. The third driver 131 is installed on the frame 11, and its telescopic end is fixedly connected to the mounting frame 132, used to drive the mounting frame 132 to move towards or away from the barrel 3. The driving wheels 134 and the auxiliary wheels 133 are respectively rotatably installed on the mounting frames 132 on both sides of the frame 11. The contact surfaces of the drive wheel 134 and auxiliary wheel 133 with the barrel 3 need to be covered with soft materials such as rubber or polyurethane to prevent marks from being left on the surface of the barrel 3 when it rotates. After the barrel 3 enters the processing position, the drive wheel 134 drives the barrel 3 to rotate until the barrel opening sensor detects that the barrel opening has rotated to the designated position. Specifically, the third actuator 131 is a push cylinder.

[0063] The frame 11 is also equipped with several upper pressure rollers 12, which are located above the barrel 3 and are arranged at intervals along the circumference of the barrel 3; during processing, the upper pressure rollers 12 press against the top edge of the barrel 3.

[0064] The processing principle of the grinding device 1 is as follows: The lifting platform 14 drives the barrel 3 to rise. After the barrel 3 reaches the specified height, the barrel lid pressure roller sensor detects that the barrel 3 has risen. The drive component 13 clamps the barrel 3 from both sides and drives the barrel 3 to rotate through friction. When the barrel mouth sensor detects that the barrel mouth has rotated to the specified position, the rotation stops. Then, the positioning component 15 descends to the specified position. At this time, the figure-eight claws 155 of the positioning component 15 are located in front of the barrel mouth. The drive component 13 drives the barrel 3 to continue rotating until the barrel mouth is engaged with the figure-eight claws 155 from the wide end. The positioning component 15 positions the barrel mouth. Afterward, the grinding and cleaning component 16 moves to the positioning component 15. The sensor at the front end of the grinding and cleaning component 16 touches the base plate 154 above the figure-eight claws 155 of the positioning component 15, thereby enabling the grinding and cleaning component 16 to obtain the position data of the barrel mouth. Then, the rotating jaw 164 moves to the top of the bucket lid and removes the bucket lid by clamping and rotating it. The polishing brush head 163 moves to the top of the bucket opening and polishes the bucket opening using the polishing brush head 163.

[0065] A sealing device 2 is installed above the rust prevention station to seal the top of the barrel 3 during rust prevention treatment. The sealing device 2 includes a fifth actuator 21, a sealing pad 24, a limiting block 23, and a pad limiting rod 22. The fifth actuator 21 is installed on the frame 11. The driving end of the fifth actuator 21 passes through the frame 11, and the sealing pad 24 is fixedly installed at its bottom end, which is used to drive the sealing pad 24 to rise and fall. The limiting blocks 23 are fixedly installed on both sides of the frame 11. The pad limiting rod 22 passes vertically through the limiting blocks 23 and moves up and down relative to the limiting blocks 23. The bottom end of the pad limiting rod 22 is fixedly connected to the sealing pad 24.

[0066] This invention provides a process for processing the opening of a vertical barrel, comprising the following steps:

[0067] S1. After the barrel 3 is flipped into a vertical position by the flipping device, it is sent into the feed end of the conveyor line 4.

[0068] S2, the barrel body 3 is transported to the processing station, and the barrel mouth is polished by the polishing device 1.

[0069] S3. After the barrel mouth is polished, the barrel body 3 continues to be transported to the rust prevention station via the conveyor line 4. The sealing device 2 presses the top of the barrel body 3 to seal it, and at the same time, the rust prevention spray is applied to the inside of the barrel body 3 from the bottom.

[0070] S4 and barrel 3 are transported out via conveyor belt.

[0071] The polishing process in S2 includes the following steps:

[0072] S21. After the barrel 3 enters the work station, it is driven to rise to the specified height by the lifting platform 14.

[0073] S22. The bucket opening is rotated to the designated position by the drive component 13, the positioning component 15 is lowered to the front of the bucket opening, and then the drive component 13 continues to drive the bucket body 3 to rotate until the bucket opening is engaged with the positioning component 15.

[0074] S23. The grinding and cleaning component 16 moves to the position of the positioning component 15, and the position of the positioning component 15 is detected by the sensor, thereby obtaining the position data of the barrel opening.

[0075] S24. After the grinding and cleaning component 16 obtains the position data of the barrel opening, the rotating jaw 164 moves to the top of the barrel cover and removes the barrel cover by clamping and rotating. The grinding brush head 163 moves to the top of the barrel opening to grind the barrel opening.

[0076] S25. After grinding is completed, the rotating chuck 164 moves the barrel lid back to its original position or places it in the designated position. Then the lifting platform 14 descends and the barrel 3 is transported to the next station via the conveyor line 4.

[0077] Specifically, after entering the processing station, the lid pressure roller sensor detects that the lid has risen to the predetermined height and sends a signal to the control system, which then controls the lifting platform 14 to stop rising. When the drive component 13 drives the barrel body 3 to rotate, the barrel opening sensor detects that the barrel opening has moved to the designated position and sends a signal to the control system, which then controls the drive component 13 to stop operating.
