Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to an automatic cover-opening device for chemical raw material barrels. Background Art

[0002] Chemical raw material barrels are special containers used to store and transport various chemical raw materials and products; they are widely used in the petroleum, pharmaceutical, dye, pesticide and other chemical industries and are an indispensable part of the modern chemical industry.

[0003] During the filling process of chemical raw material barrels, the lids must be removed; however, the current automatic lid-opening device requires the electric claw to move not only up and down, but also horizontally reciprocating to achieve the automatic lid-opening function, which takes a long time. Therefore, it is necessary to design an automatic lid-opening device for chemical raw material barrels. Summary of the Invention

[0004] The purpose of the utility model is to solve the above problems in the existing technology and to propose an automatic lid-opening device for chemical raw material barrels.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an automatic lid-opening device for chemical raw material barrels, comprising a frame, a plurality of conveying rollers for conveying chemical raw material barrels are provided on the frame, four centering rollers for centering the chemical raw material barrels are provided on the frame, and the centering rollers can move closer to or farther away from each other, one of the centering rollers is connected to a driving motor that enables it to rotate, and a vertical frame is fixed to the frame through a mounting column, an electric linear rail is vertically mounted on the vertical frame, a lifting seat is mounted on the slide of the electric linear rail, a servo motor is mounted on the lifting seat, the output shaft of the servo motor is vertically downward, and an electric claw for clamping the barrel cover is mounted on the end of the output shaft of the servo motor, and a cylinder 1 is also horizontally mounted on the vertical frame, and the piston rod end of the cylinder 1 is connected to an export trough body for exporting the barrel cover, and the export trough body is arranged inclined.

[0006] The lifting seat is also provided with an auxiliary block, on which a second cylinder is vertically mounted. The end of the piston rod of the second cylinder is connected to a positioning rod through a spring, and a travel switch is connected to the positioning rod.

[0007] The end of the piston rod of the first cylinder is connected to the lead-out groove body through a U-shaped piece.

[0008] The positioning rod is in an L-shape.

[0009] An electric control box is also installed on the frame, and the drive motor, servo motor, electric claw, electric linear track, travel switch, cylinder 1 and cylinder 2 are all electrically connected to the electric control box through circuits.

[0010] Compared with the existing technology, the automatic lid opening device for chemical raw material barrels has the following advantages:

[0011] In the utility model, the chemical raw material barrel on the frame is centered by the centering roller. At the same time, the driving motor drives the centering roller connected to it to rotate. With the cooperation of the travel switch on the positioning rod, the barrel cover of the chemical raw material barrel is located directly below the electric claw. When the electric claw clamps the barrel cover, the barrel cover can be smoothly screwed down with the help of the coordinated action of the servo motor and the electric linear track. Subsequently, the lead-out trough body is moved to the bottom of the electric claw through the action of the second cylinder. The barrel cover on the electric claw immediately falls into the lead-out trough body and is led out along the trough body, thereby simplifying the movement trajectory of the electric claw.

DETAILED DESCRIPTION

[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figures 1-4As shown, the automatic uncovering device for chemical raw material barrels includes a frame 1, on which are provided a plurality of conveying rollers 20 for conveying chemical raw material barrels. In this embodiment, the conveying rollers 20 adopt an existing structure to rotate as needed; the frame 1 has four centering rollers 3 for centering the chemical raw material barrels, and the centering rollers 3 can move closer to or farther away from each other. In this embodiment, the centering rollers 3 can move closer to or farther away from each other by adopting existing technology; one of the centering rollers 3 is also connected to a driving motor 15 that enables it to rotate, so that after it is centered and clamped, the driving motor 15 is used to drive the centering roller 3 connected to it to rotate, so that the chemical raw material barrel can be Rotation, this adopts the existing technology; the frame 1 is also fixed with a stand 4 through the mounting column 5, the stand 4 is vertically mounted with an electric linear rail 17, the slide 18 of the electric linear rail 17 is mounted with a lifting seat 13, the lifting seat 13 is mounted with a servo motor 19, the output shaft of the servo motor 19 is vertically downward, and the end of the output shaft of the servo motor 19 is mounted with an electric claw 7 for clamping the barrel cover, and the stand 4 is also horizontally mounted with a cylinder 16, the end of the piston rod of the cylinder 16 is connected with the lead-out trough 6 for leading out the barrel cover, and the lead-out trough 6 is arranged obliquely, specifically: the end of the piston rod of the cylinder 16 is connected with the lead-out trough 6 through the U-shaped part 14.

[0019] The lifting seat 13 also has an auxiliary block 11, and a cylinder 2 12 is vertically installed on the auxiliary block 11. The end of the piston rod of the cylinder 2 12 is connected to the positioning rod 9 through a spring 10, and the positioning rod 9 is connected to the travel switch 8. Specifically: the positioning rod 9 is L-shaped. With this structure, when the chemical raw material barrel needs to be positioned, the positioning rod 9 is driven downward by the cylinder 2 12. As the chemical raw material barrel rotates, the barrel cover on the chemical raw material barrel will contact the travel switch 8, thereby stopping the drive motor 15. At this time, the barrel cover is just located directly below the electric claw 7. In this embodiment, the up and down movement of the positioning rod 9 will not interfere with the electric claw 7.

[0020] An electric control box 2 is also installed on the frame 1. The drive motor 15, servo motor 19, electric claw 7, electric linear rail 17, limit switch 8, cylinder 16 and cylinder 2 12 are all electrically connected to the electric control box 2 through lines. This adopts the existing technology and its circuits do not need to be redesigned.

[0021] In the utility model, the chemical raw material barrel at the frame 1 is centered by the centering roller 3. At the same time, the driving motor 15 drives the centering roller 3 connected thereto to rotate. With the cooperation of the travel switch 8 on the positioning rod 9, the barrel cover of the chemical raw material barrel is located directly below the electric claw 7. After the electric claw 7 clamps the barrel cover, the barrel cover can be smoothly unscrewed with the help of the coordinated action of the servo motor 19 and the electric linear rail 17; subsequently, the lead-out trough 6 is moved to the bottom of the electric claw 7 by the action of the second cylinder 12, and the barrel cover on the electric claw 7 immediately falls into the lead-out trough 6 and is led out along the trough, thereby simplifying the movement trajectory of the electric claw 7.

[0022] The above components are all common standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.

[0023] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
