[0002] In agricultural production, as an important means of production, the safe and efficient packaging of pesticides is crucial. Currently, pesticide products are widely packaged in plastic packaging barrels. These packaging barrels are mainly produced in large quantities by injection molding or blow molding processes. During the production process of plastic barrels (especially those made of HDPE material), when the molten plastic is formed in the mold and cools down, excess plastic edge material, commonly known as "flash" or "gate material", is inevitably formed at the barrel opening (usually the flange or threaded area) and the mold parting line or gate position.

The traditional cutting method is to directly cut off the edge material by workers using an angle grinder or a blade. This method not only produces a large amount of burrs, debris, and other impurities at the cutting position, which requires subsequent deburring or chamfering operations, but also consumes a large amount of labor, with high work intensity and difficulty, and low work efficiency.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. The embodiments are written in a progressive manner.
[0019] As shown in Figures 1 to 7 A cutting device for removing the edge material of pesticide packaging barrels of the present application, which comprises a tray 2 for carrying the packaging barrel 1, a supporting unit 3 and two cutting wheels 4 oppositely arranged on the supporting unit 3, one cutting wheel 4 is located on the outside of the packaging barrel 1 and cuts the edge material, and the other cutting wheel 4 is located on the inside of the packaging barrel 1 and cuts the edge material; The cutting wheel 4 comprises a cutting edge part 5 for cutting operation, a chamfering part 6 for chamfering operation and a plurality of cutting edges 7 on the cutting edge part 5; In the present application, the tray 2 is used to support the packaging barrel 1, the supporting unit 3 is used to support the two cutting wheels 4, and the tray 2 and the supporting unit 3 can move relative to each other with the axis of the tray 2 as the reference axis, so that the supporting unit 3 drives the two cutting wheels 4 on it to rotate around the packaging barrel 1, and the two cutting wheels 4 rotate to cut off the edge material at the position of the barrel opening of the packaging barrel 1; Since the two cutting wheels 4 cut synchronously from the inside and outside of the packaging barrel 1, no debris will be generated on the cutting edge, the cutting will be smooth, and the subsequent operation of cleaning burrs and debris will be avoided; In order to drive the cutting wheel 4 to rotate, a motor or other structure can be configured for each cutting wheel 4, so as to realize high-speed rotary cutting work, and if no motor or other structure is provided, the cutting wheel 4 will only roll on the packaging barrel 1, at this time, the two cutting wheels 4 will realize rolling cutting work on the edge material on the packaging barrel 1, both of the above cutting methods can realize the cutting treatment of the edge material, and in different use environments, the two methods can be selected; When in use, the packaging barrel 1 is fixed on the pallet 2, and the two cutting wheels 4 on the supporting unit 3 are respectively moved to the inner and outer sides of the packaging barrel 1, so that the two cutting wheels 4 rotate and approach each other, and the two cutting wheels 4 squeeze and cut the inner and outer sides of the edge material. At this time, the cutting edge 5 on the cutting wheel 4 mainly realizes the cutting work, and the cutting edge 7 on the cutting edge 5 mainly realizes the scraping and cutting work. The chamfering part 6 on the cutting wheel 4 is mainly used to chamfer the incision position on the inner or outer side of the edge material on the packaging barrel 1. In this way, the incision is chamfered simultaneously when the edge material is cut, so that the rapid cutting and correction work of the packaging barrel 1 can be realized; It should be pointed out that the two cutting wheels 4 can be located on the same side of the axis of the packaging barrel 1 and close to each other, or the two cutting wheels 4 can be located on both sides of the axis of the packaging barrel 1 and away from each other. Both methods can achieve the cutting of the edge material. When the two cutting wheels 4 are on the same side, the forces exerted by the two cutting wheels 4 on the packaging barrel 1 are opposite, that is, the forces are offset, thereby ensuring that the packaging barrel 1 will not be deformed due to uneven force. When the two cutting wheels 4 are located on both sides of the axis of the packaging barrel 1, the forces exerted by the two cutting wheels 4 on the packaging barrel 1 are in the same direction. At this time, both the cutting wheel 4 located on the outside and the cutting wheel 4 located on the inside can directly cut through part of the edge material. This form is similar to the traditional method of cutting with a single cutting wheel 4, but the cutting of the two cutting wheels 4 will simultaneously remove the burrs generated by the cutting. Therefore, different cutting methods can be achieved by utilizing the different distribution positions of the two cutting wheels 4. Combined with the above-mentioned active rotary cutting and rolling cutting methods, multi-form cutting operations can be achieved. By using the two cutting wheels 4 to cut the inner and outer sides of the edge material at the barrel mouth position of the packaging barrel 1, and simultaneously performing chamfering when cutting the edge material, the barrel mouth shape of the packaging barrel 1 can be directly formed, avoiding the generation of burrs, saving the subsequent burr cleaning and chamfering operations, simplifying the processing steps of the packaging barrel 1, and making the edge material cutting work simpler and easier to operate, saving manpower and improving efficiency; since there are multiple cutting methods and distribution methods of the two cutting wheels 4, multiple cutting modes can be realized, which is convenient for selecting different modes according to different work needs, thereby improving ease of use.
[0020] Furthermore, the support unit 3 includes a support rod 8, two sliders 9 slidably mounted on the support rod 8, and a secondary rod 10 parallel to the support rod 8. The two cutting wheels 4 are respectively mounted on the two sliders 9. An adjusting rod 11 is slidably provided on each slider 9, and the two adjusting rods 11 are relatively inclined. Both adjusting rods 11 are rotatably connected to the secondary rod 10. The support rod 8 and the two sliding blocks 9 can support the two cutting wheels 4, and since the two cutting wheels 4 can approach or move away from each other, the sliding blocks 9 are needed to move the cutting wheels 4, the auxiliary rod 10 and the adjusting rod 11 can be used to adjust the position relationship of the two cutting wheels 4, when the support rod 8 and the auxiliary rod 10 approach or move away from each other, the opening angle between the two adjusting rods 11 decreases or increases, so that the two sliding blocks 9 approach or move away from each other; By arranging the auxiliary rod 10 and the adjusting rod 11, the midpoint position of the vertical line between the two cutting wheels 4 can be limited, thereby assisting the positioning of the relative position and the processing position of the two cutting wheels 4.
[0021] Further, the auxiliary rod 10 is provided with a guide sleeve 12, and the auxiliary rod 10 reciprocates along the radial direction of the packaging barrel 1 on the guide sleeve 12; Among them, the safety gap is arranged between the two cutting wheels 4; When the two cutting wheels 4 are located on the same side of the packaging barrel 1 and process the edge material, in order to avoid the collision between the two cutting wheels 4 and cause damage, when the two cutting wheels 4 are at the shortest distance, there is still a gap between the two cutting wheels 4, which is the safety gap, and the existence of the gap will cause tail material when the two cutting wheels 4 cut the edge material, which will cause the edge material to be completely cut off, in order to avoid this phenomenon, the auxiliary rod 10 can reciprocate on the guide sleeve 12, so that the two cutting wheels 4 can reciprocate along the radial direction of the packaging barrel 1 when cutting the edge material, and the cutting area of the two cutting wheels 4 will overlap, thereby avoiding the generation of tail material; It should be pointed out that when the cutting wheel 4 reciprocates, the movement interval is smaller than the thickness of the edge material, that is, the cutting position of the cutting wheel 4 is always located inside the edge material.
[0022] Further, the cutting device further comprises a rotating disc 13, a base 14 and a core column 16, the number of the trays 2 and the support units 3 is arranged as several, and the several trays 2 are annularly distributed on the rotating disc 13, the tray 2 rotates on the rotating disc 13, the rotating disc 13 rotates and is arranged on the base 14, each rotating disc 13 is provided with a rolling ring 15, and the rolling ring 15 is in transmission contact with the inner wall of the base 14; The core column 16 is coaxially fixed on the rotating disc 13, the several rotating discs 13 are annularly distributed on the outer wall of the core column 16, and the guide sleeve 12 is fixed on the core column 16; The base 14 is used to support the rotating disc 13, and the arrangement of the plurality of trays 2 can realize the circumferential conveying of the plurality of packaging barrels 1 when the rotating disc 13 rotates, so as to realize the synchronization of the cutting of the edge material and the conveying of the packaging barrel 1, improve the continuity of the packaging barrel 1 processing, and avoid the waiting time and time waste in static cutting; when the rotating disc 13 rotates on the base 14, the rolling ring 15 rolls on the base 14 synchronously, so that the tray 2 drives the packaging barrel 1 to rotate, the core column 16 moves synchronously with the rotating disc 13, and the plurality of supporting units 3 move synchronously with the tray 2; the rotation of the rotating disc 13 can be powered by a motor. In actual use, the rotating disc 13 rotates and moves the tray 2 to a feeding position, fixes the packaging barrel 1 on the tray 2, and cuts the packaging barrel 1 on the corresponding supporting unit 3 with the cutting wheel 4 as the tray 2 moves, so that the packaging barrel 1 completes the edge cutting work when the packaging barrel 1 reaches a discharging position, thereby realizing the purpose of continuous production.
[0023] Further, the core column 16 is provided with a moving body 17, the number of the moving body 17 is one or consistent with the number of the supporting unit 3, the supporting rod 8 is arranged on the moving body 17, and the moving body 17 is pushed to move by a cylinder 18; the moving body 17 can be used to support the supporting rod 8, and the movement of the moving body 17 on the core column 16 can adjust the distance between the supporting rod 8 and the auxiliary rod 10; when one moving body 17 is used, the cylinder 18 pushes the moving body 17 to move and drives the plurality of supporting rods 8 to move synchronously, so that the two cutting wheels 4 on the plurality of supporting units 3 are synchronously separated or close to each other, and at this time, the plurality of packaging barrels 1 on the rotating disc 13 can realize synchronous processing operation; when a plurality of moving bodies 17 are used, one moving body 17 and the cylinder 18 are arranged on each supporting rod 8, so that the movement of each supporting rod 8 can be controlled individually, so as to adjust the distance between the supporting rod 8 and the auxiliary rod 10 according to the moving position of the tray 2.
[0024] Further, the core column 16 is provided with a top disc 19, the end face of the top disc 19 is provided with an annular wave groove 20, and a plurality of sliding columns 21 are slidably arranged in the annular wave groove 20; the sliding column 21 is connected with the corresponding auxiliary rod 10. The top disc 19 rotates on the core column 16, so that the top disc 19 moves relative to each auxiliary rod 10, and the rotating power of the top disc 19 can be provided by a motor arranged on the core column 16; when the top disc 19 moves relative to the auxiliary rod 10, the sliding column 21 slides in the annular wave groove 20, and due to the shape characteristics of the annular wave groove 20, the sliding column 21 repeatedly approaches or moves away from the axis of the core column 16, the sliding column 21 drives the auxiliary rod 10 to move synchronously, so that the two cutting wheels 4 reciprocate when cutting the edge material.
[0025] Further, each tray 2 is provided with a clamping part for clamping the packaging barrel 1, the clamping part comprises a plurality of arc-shaped receiving grooves 22 opened on the tray 2 and distributed circumferentially around the tray 2, the arc-shaped receiving groove 22 is coaxial with the tray 2, a rotating body 23 is rotatably arranged in the arc-shaped receiving groove 22, a pressing arm 24 is arranged on the outer wall of the rotating body 23, and the pressing arm 24 is used for side pressing the packaging barrel 1; A transmission ring 26 is rotatably arranged at the bottom of the tray 2, and the transmission ring 26 is in transmission contact with each rotating body 23; By using the arc-shaped receiving groove 22, the rotating body 23 and the pressing arm 24 can be conveniently stored and hidden, so as to provide enough space for the disassembly and assembly work of the packaging barrel 1 on the tray 2. Since the pressing arm 24 is stored in the arc-shaped receiving groove 22, the shape of the pressing arm 24 is consistent with the shape of the arc-shaped receiving groove 22. When the rotating body 23 rotates, the vertical distance between the end of the pressing arm 24 away from the rotating body 23 and the axis of the tray 2 gradually decreases. By using this characteristic, the pressing arm 24 gradually approaches the outer wall of the packaging barrel 1. The plurality of pressing arms 24 move synchronously and contact the outer wall of the packaging barrel 1, so that the plurality of pressing arms 24 side push and press the packaging barrel 1 to be fixed. The transmission ring 26 can synchronously provide rotary power for the plurality of rotating bodies 23, so that the plurality of rotating bodies 23 move synchronously, and the axis operation of the packaging barrel 1 is facilitated.
[0026] Further, a suction hole is opened in the middle of the tray 2, a polygonal cylinder 27 and a rotating sleeve 25 are rotatably arranged at the bottom of the tray 2, the rotating sleeve 25 is connected with the transmission ring 26, the polygonal cylinder 27 is located on the inner side of the rotating sleeve 25, and the polygonal cylinder 27 and the rotating sleeve 25 are connected through a torsion spring 29, and a secondary barrel 28 is slidably arranged on the polygonal cylinder 27; A plurality of spiral grooves 30 are opened on the inner wall of the rotating sleeve 25, and a sliding column II 31 is slidably arranged in each spiral groove 30, and the sliding column II 31 is connected with the secondary barrel 28; The secondary barrel 28 can be driven to rotate by a motor, the secondary barrel 28 drives the polygonal cylinder 27 to rotate synchronously, the polygonal cylinder 27 drives the rotating sleeve 25 and the transmission ring 26 to rotate synchronously through the torsion spring 29, thereby providing driving power for the plurality of rotating bodies 23. When the plurality of pressing arms 24 fix the packaging barrel 1, the plurality of rotating bodies 23 stop moving, the rotating sleeve 25 stops rotating, and at this time the secondary barrel 28 continues to move, the torsion spring 29 is elastically deformed, and the secondary barrel 28 drives the sliding column II 31 to slide in the sliding column II 31, the spiral groove 30 and the sliding column II 31 drive the secondary barrel 28 to move along the axis of the tray 2 in the opposite direction, thereby making the secondary barrel 28 slide relative to the polygonal cylinder 27, the space between the secondary barrel 28 and the polygonal cylinder 27 increases and forms a negative pressure, and the negative pressure adsorbs and fixes the bottom of the packaging barrel 1 through the suction hole, thereby realizing the operation mode of clamping positioning first and then adsorbing fixation.
[0027] The above merely is the preferred embodiment of the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, can also make several improvements and variations, these improvements and variations also should be considered as the protection scope of the present application.
