Description

Technical Field

[0001] The invention relates to a device for opening an outer cover of a solvent barrel and a working method thereof. Background Art

[0002] In a lithium battery production workshop, the front-end pulping process includes batching, adding powder, weighing the powder, conveying the powder to a mixer, adding the solvent formula to the mixer, stirring the mixer to form a slurry, and conveying the slurry to a transfer tank at the head and tail of the coating machine for coating. This completes the process connection from pulping to sheeting for lithium battery cells. In the solvent filling system of this process, the front-end feeder needs to solve the problem of opening the solvent barrel lid. For example, a 200L solvent barrel has two lids. The inner lid is a sealing lid that is locked with a thread and a sealing ring. The back has a cross hole that allows for easy unscrewing and reuse. The outer lid is a dust and water-resistant cover with a snap-on design. Once the lid is tightened, it cannot be easily opened and requires destructive opening, which will damage the outer lid. Therefore, it cannot be reused and is a disposable lid. The lid of a 200L solvent drum has two grooves and a small tail attached. To manually open the lid, you first need to cut the two grooves with a knife. Then, pull the small tail between the two grooves to open the lid into a figure-eight shape. The buckle on the lid will easily fall off, allowing the lid to be opened. This process is not only tedious and laborious, but can also easily injure the hands of the person opening the lid.

[0003] In view of the above-mentioned shortcomings of the prior art for opening the outer cover, the present invention provides a device for opening the outer cover of a solvent barrel, which realizes the mechanization of opening the outer cover of the solvent barrel, not only saving manpower but also simplifying the process. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a solvent barrel cover opening device and a working method thereof.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a device for opening the outer cover of a solvent barrel, comprising a frame, a movable seat body driven to rise and fall by a first driving mechanism is provided on the frame, a capping mechanism and a rotary cutting mechanism are provided on the movable seat body, and the rotary cutting mechanism includes a cap cutting assembly and a cap removing assembly.

[0006] Preferably, the cover pressing mechanism comprises an axially vertical cover pressing sleeve, and a lifting buffer assembly is connected between the cover pressing sleeve and the movable seat body.

[0007] Preferably, the capping assembly includes a capping blade, and the capping blade is driven to rotate by a capping motor.

[0008] Preferably, the cover removal assembly includes an axially vertical cover removal screw.

[0009] Preferably, a second driving mechanism is connected between the peeling mechanism and the movable seat body to drive the lifting and lowering adjustment of the peeling mechanism.

[0010] Preferably, a cover removal assembly is provided directly below the cover removal screw.

[0011] Preferably, the cover removal assembly includes a cover removal top plate capable of vertical sliding, and the cover removal top plate is provided with a clearance through hole coaxial with the cover removal screw.

[0012] Preferably, a plurality of gland nails are evenly distributed around the circumference of the bottom end of the gland sleeve.

[0013] Preferably, the lifting buffer assembly includes a first buffer spring connected between the gland sleeve and the movable seat body, the axial direction of the first buffer spring is vertical, and an in-position sensor assembly is also provided between the gland sleeve and the movable seat body.

[0014] A working method of a solvent barrel outer cover opening device is carried out according to the following steps: S1: In the initial state, the rotary cutting mechanism is at the end of the downward movement; S2: The movable seat moves downward for a distance, so that the cover removal screw and the cover cutting blade penetrate into the outer cover, and the bottom end of the cover pressing sleeve contacts the outer cover by the cover pressing pin but does not penetrate the outer cover, and the first buffer spring is compressed; S3: The capping motor drives the capping screw and the capping blade to rotate. When the capping screw and the capping blade rotate more than one circle, a circle is cut off at the position of the capping blade. S4: The movable seat body moves upward, the cover sleeve returns to its original position downward, the external thread of the cover removal screw clamps the cut outer cover, and the cut outer cover is removed upward; S5: When the cover needs to be discarded, the cover removal top plate pushes the cut outer cover downwards away from the cover removal screw, so that the cut outer cover is separated from the cover removal screw and the cover cutting blade and falls off, thus completing a complete outer cover opening action.

[0015] Compared with the prior art, the present invention has the following advantages: the solvent barrel outer cover opening device has a simple structure and a reasonable design. The capping mechanism is used to press the outer cover to prevent it from rotating during rotary cutting; the capping assembly is used to penetrate the outer cover and rotary cut it; and the capping assembly is used to remove the cut outer cover.

[0016] The solvent barrel outer cover opening device realizes the mechanization of solvent barrel outer cover opening, which not only saves manpower but also simplifies the process.

[0056] In an embodiment of the present invention, the working principle of the solvent barrel cover opening device is as follows: The initial state of the cover removal cylinder is extended, and the motor mounting plate is at the lower end position.

[0057] The movable seat moves downward, so that the cover removal screw and the cover cutting blade penetrate into the outer cover, and the bottom end of the cover pressing sleeve presses the outer cover 27 (it uses the cover pressing nail to contact the outer cover but does not pierce the outer cover to prevent the outer cover from rotating when being peeled), and the first buffer spring is compressed until the upward moving sensor hits the sensor and the movable seat stops moving downward (such as Figure 6 、 Figure 7 shown).

[0058] At this time, the cover cutting motor drives the rotating shaft to drive the cover removing screw and the cover cutting blade to rotate. When the cover removing screw and the cover cutting blade rotate more than one circle, the outer cover is cut into a circle at the position of the cover cutting blade.

[0059] At this time, the movable seat body moves upward, the cover sleeve resets downward, the outer thread of the cover removal screw clamps the cut outer cover, and the cut outer cover is taken away by the upper part (such as Figure 8 shown).

[0060] When the cover needs to be thrown, the cover removal cylinder drives the motor mounting plate to move upward, the cut outer cover moves upward and pushes the cover removal top plate upward. When the cover removal top block of the cover removal top plate moves upward and touches the bottom surface of the connecting end cover, the cover removal top plate cannot move further upward (such as Figure 9 As shown), at this time, as the motor mounting plate and the rotating shaft continue to move upward, the cover removal top plate begins to push the cut outer cover downward away from the cover removal screw, so that the cut outer cover is separated from the cover removal screw and the cover cutting blade and falls off, thus completing a complete outer cover opening action.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other manner. Any person skilled in the art may utilize the above-disclosed technical content to modify or modify the present invention into equivalent embodiments. However, any simple modifications, equivalent variations, and modifications to the above embodiments that do not depart from the technical content of the present invention and are based on the technical essence of the present invention remain within the scope of protection of the present invention.
