Description

Technical Field

[0001] This utility model relates to the field of hopper cleaning technology, specifically a hopper cleaning machine that can automatically pick up and put down the lid. Background Technology

[0002] In the prior art, hoppers containing materials need to be placed in a cleaning machine for cleaning after use. The applicant has been developing hopper cleaning structures for a long time. However, before the hopper to be cleaned is sent into the hopper cleaning chamber, the hopper cover usually needs to be removed manually so that the cleaning nozzles can directly enter the hopper for spray cleaning. After cleaning, the hopper cover is then replaced manually, which reduces the cleaning efficiency of the hopper. In addition, since the hoppers containing industrial raw materials are very large and the hopper cover is located at a high position, manual removal and placement of the cover requires the assistance of lifting structures or frames, resulting in the need for cumbersome equipment or structures in the cleaning workshop.

[0003] To solve the above-mentioned technical problems, the applicant has designed a hopper cleaning machine that can automatically pick up and place lids, which can pick up and place lids in the hopper cleaning chamber to save manpower and improve efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings and deficiencies of the existing technology and to provide a hopper cleaning machine that can automatically pick up and place the lid. The technical solution adopted by this utility model is as follows:

[0005] An automatic lid-retrieving hopper cleaning machine includes a hopper cleaning chamber. An upper cleaning pipe and a lid-retrieving assembly are located at the upper part of the hopper cleaning chamber. The upper cleaning pipe includes a pipe lifting mechanism and a cleaning pipe. The lid-retrieving assembly includes a rotating cylinder, a vacuum tube, a lifting cylinder, and a vacuum suction cup. The rotating cylinder drives the vacuum suction cup to rotate within the cleaning chamber. The lifting cylinder drives the vacuum suction cup to rise and fall within the cleaning chamber. The vacuum tube controls the vacuum suction cup to generate negative pressure to adsorb the hopper lid. The pipe lifting mechanism drives the cleaning pipe to rise and fall relative to the hopper.

[0006] Preferably, a hopper cover cleaning pipe is provided on the side of the hopper cleaning chamber. The rotating cylinder drives the vacuum suction cup to rotate in the cleaning chamber through the rotating shaft, so that the vacuum suction cup has a position above the hopper to pick up the hopper cover, and the vacuum suction cup has a cleaning position to keep the hopper cover in the vicinity of the hopper cover cleaning pipe.

[0007] Preferably, the hopper cover cleaning pipe includes a first pipe and a second pipe. When the vacuum suction cup adsorbs the hopper cover and moves it to the cleaning position, the first pipe is located above the hopper cover and the second pipe is located below the hopper cover. The first pipe sprays downward and the second pipe rinses upward.

[0008] Preferably, the rotating shaft and the vacuum tube are linked together by a linkage plate, and the vacuum tube and the vacuum suction cup rotate synchronously with the rotating shaft. The connection of the linkage plate allows the vacuum tube and the vacuum suction cup to rotate synchronously with the rotating shaft, which helps to keep the vacuum suction cup stably adsorbing the hopper cover during rotation.

[0009] Preferably, the vacuum tube further includes a rotating horizontal section, one end of which is connected to a rotating shaft, and the other end is linked to the lifting cylinder. During the process of the lifting cylinder driving the vacuum suction cup to rise and fall, the vacuum tube is always connected to the vacuum suction cup. There are multiple options for the connection between the vacuum tube at the lifting cylinder and the vacuum suction cup, such as designing this section of vacuum pipe as a rigid telescopic sleeve or a flexible corrugated pipe.

[0010] Preferably, both the rotating cylinder and the lifting cylinder are equipped with positioning detection components, and the vacuum suction cup is equipped with a vacuum degree detection device.

[0011] Preferably, the cleaning chamber frame of the hopper also includes a rotating chassis, which is fitted with a lower cleaning pipeline. The lower cleaning pipeline includes a lifting spray device corresponding to the discharge port below the hopper. During cleaning, the lifting spray device rises from the discharge port and extends into the hopper to clean the inner wall of the hopper.

[0012] Preferably, the cleaning chamber frame is connected to a revolving door, and the revolving door is provided with an observation window.

[0013] The beneficial effects of this utility model are as follows: This cleaning machine can automatically pick up and put down the hopper lid while it is entering and leaving the cleaning chamber, reducing labor costs and improving production efficiency. After the lid is picked up, the hopper lid can be cleaned and dried simultaneously in the cleaning chamber, saving cleaning steps and cleaning resources. Attached Figure Description

[0024] Example 1

[0025] like Figure 1-5 As shown, an automatic lid-retrieving hopper washing machine includes a hopper washing chamber and a transport track 34. An upper washing pipe 1 and a lid-retrieving assembly are located above the washing chamber frame 3 inside the hopper washing chamber. The upper washing pipe 1 includes a pipe lifting mechanism 11 and a washing pipe 12. The lid-retrieving assembly includes a rotating cylinder 21, a vacuum pipe 22, a lifting cylinder 23, and a vacuum suction cup 24. The rotating cylinder 21 drives the vacuum suction cup 24 to rotate within the washing chamber, and the lifting cylinder 23 drives the vacuum suction cup 24 to rise and fall within the washing chamber. The vacuum pipe 22 controls the vacuum suction cup 24 to generate negative pressure to adsorb the hopper lid 2. The pipe lifting mechanism 11 drives the washing pipe 1 to rise and fall relative to the hopper 4, extending into the hopper opening when the hopper lid 2 is open relative to the hopper 4.

[0026] A hopper cover cleaning pipe 32 is provided on the side of the cleaning chamber frame 3 in the hopper cleaning chamber. The rotating cylinder 21 drives the vacuum suction cup 24 to rotate in the cleaning chamber through the rotating shaft 211, so that the vacuum suction cup 24 has a position above the hopper 4 to pick up the hopper cover 2, and the vacuum suction cup 24 has a cleaning position to keep the hopper cover 2 in the vicinity of the hopper cover cleaning pipe 32.

[0027] The hopper cover cleaning pipe 32 includes a first pipe 321 and a second pipe 322. When the vacuum suction cup 24 adsorbs the hopper cover 2 and moves it to the cleaning position, the first pipe 321 is located above the hopper cover 2 and the second pipe 322 is located below the hopper cover 2. The first pipe 321 sprays downward and the second pipe 322 rinses upward.

[0028] The rotating shaft 211 and the vacuum tube 22 are linked together by the linkage plate 221. The vacuum tube 22 and the vacuum suction cup 24 rotate synchronously with the rotating shaft 211. The connection of the linkage plate 221 and the synchronous rotation of the vacuum tube 22 and the vacuum suction cup 24 with the rotating shaft 211 helps to keep the vacuum suction cup stably adsorbing the hopper cover during rotation.

[0029] The vacuum tube 22 also includes a rotating horizontal part 222. One end of the rotating horizontal part 222 is connected to the rotating shaft 211, and the other end is linked to the lifting cylinder 23. During the process of the lifting cylinder 23 driving the vacuum suction cup 24 to rise and fall, the vacuum tube 22 is always connected to the vacuum suction cup 24. There are multiple options for the connection between the vacuum tube 22 at the lifting cylinder 23 and the vacuum suction cup 24. For example, this section of vacuum pipe can be designed as a rigid telescopic sleeve or a flexible corrugated pipe.

[0030] Both the rotating cylinder 21 and the lifting cylinder 23 are equipped with positioning detection components, and the vacuum suction cup 24 is equipped with a vacuum degree detection device.

[0031] The cleaning chamber frame 3 of the hopper also includes a rotating base 31, which is equipped with a lower cleaning pipe 5. The lower cleaning pipe 5 includes a lifting spray device corresponding to the discharge port below the hopper 4. During cleaning, the lifting spray device rises from the discharge port and extends into the hopper to clean the inner wall of the hopper. The cleaning chamber frame 3 is connected to a rotating door 33, which is provided with an observation window.

[0032] The main functions of the above structure are as follows:

[0033] The automatic lid picking and placing function uses a rotating cylinder, a lifting cylinder, and a vacuum suction cup structure to pick up and place the hopper lid from the hopper. The rotating cylinder and the lifting cylinder are equipped with position detection, and the vacuum suction cup is equipped with vacuum detection to prevent the hopper lid from falling off during the lid picking and placing process, thus providing an alarm prompt.

[0034] In addition, a pin-type self-locking butterfly valve is installed on the hopper cover cleaning pipe. The butterfly valve is opened and closed by a pneumatic actuator. When the position detection device reports that the hopper cover is in the cleaning position, the pneumatic actuator controls the butterfly valve to open, so that the hopper cover can be cleaned in the cleaning chamber. After cleaning, the butterfly valve is closed (without affecting the operation of other cleaning pipelines in the cleaning chamber), and then the cover removal assembly sends the hopper cover back to the hopper.

[0035] This equipment effectively reduces manual intervention in the hopper cleaning process, achieving a high degree of automation. It can pick up and place the lid inside the cleaning chamber and clean it.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
