Description

Technical Field

[0001] This utility model relates to the field of steel drum processing technology, specifically to a cutting device for steel drum production. Background Technology

[0002] Edge trimming of steel drums is a key process in the production of packaging steel drums. It aims to cut the edges of the formed steel drums to remove excess material and ensure that the edges of the steel drums are flat and smooth. This process not only affects the appearance quality of the steel drums, but also directly relates to whether subsequent processes such as capping and painting can be carried out smoothly.

[0003] Traditional steel drum trimming devices typically include clamps to fix the steel drum, a motor to drive the steel drum to rotate, and a cutter to perform the trimming operation. However, when trimming the steel drum, there is a lack of effective support for the trimming area. Since the cutter generates certain stress during rotation, and the steel drum is relatively thin, the edge is prone to chipping or deformation under the stress of rotation, affecting the cutting effect. Therefore, this utility model proposes a cutting device for steel drum production. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for steel drum production in order to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A cutting device for steel drum production includes:

[0007] A base, on the top of which a bearing seat is rotatably mounted, and a fastener for fixing the steel drum is mounted on the bearing seat;

[0008] A crossbeam is mounted on a base via a lifting mechanism. One end of the crossbeam is equipped with a first arc-shaped plate, and the other end is equipped with a first electric push rod. The piston end of the first electric push rod is connected to a first movable plate. A first motor is mounted on the first movable plate, and a cutting disc is fixed to the output shaft of the first motor. A second arc-shaped plate is connected to the first movable plate via a spring telescopic rod. Both the first and second arc-shaped plates have through-cut grooves. Several rollers are rotatably mounted on both the first and second arc-shaped plates.

[0009] Furthermore, a second electric push rod is provided on the crossbeam, and a second movable plate is connected to the piston end of the second electric push rod. The first arc-shaped plate is fixed on the second movable plate.

[0010] Furthermore, a through groove is provided on the crossbeam, and both the first movable plate and the second movable plate are slidably inserted into the through groove.

[0011] Furthermore, several sliding rods are slidably arranged on both the first and second arc-shaped plates, and several rollers are rotatably arranged on the several sliding rods respectively. Limiting springs are connected between the sliding rods and the first or second arc-shaped plate.

[0012] Furthermore, the fixing component includes several sliders, the bearing seat has an internal cavity, the top of the bearing seat has several sliding grooves, the several sliders are slidably inserted into the several sliding grooves, the bottom of the bearing seat is provided with a third electric push rod, the piston end of the third electric push rod is connected to a lifting plate, the lifting plate is hinged to several sliders with support rods, and the sliders are provided with support plates.

[0013] Furthermore, one side of the support plate is arc-shaped and a rubber pad is provided on the arc-shaped surface.

[0014] Furthermore, the inner walls of the slide are provided with grooves on opposite sides, and the slider is provided with two baffles, which are slidably inserted into the two grooves respectively.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] like Figures 1-7 As shown, one embodiment of this utility model discloses a cutting device for steel drum production, comprising:

[0028] A base 1 has a bearing seat 2 rotatably mounted on its top. Preferably, the base 1 has an internal hollow structure, and the bottom of the bearing seat 2 has a connecting column that rotatably penetrates the inner top wall of the base 1. A drive motor is installed inside the base 1, and gears are fixed on both the output shaft of the drive motor and the connecting column. The two gears mesh, and the drive motor performs work. Through the meshing of the two gears, the bearing seat 2 is driven to rotate. The bearing seat 2 is equipped with a fixing member 3 for fixing the steel drum. The steel drum (without caps at both ends) is erected on the bearing seat 2 and fixed by the fixing member 3. The drive motor drives the bearing seat 2 to rotate, thereby driving the steel drum to rotate, and the cutting member cuts the circumferential edge of the drum.

[0029] A crossbeam 4 is mounted on a base 1 via a lifting component 5. One end of the crossbeam 4 has a first arc-shaped plate 6, and the other end has a first electric push rod 7. The piston end of the first electric push rod 7 is connected to a first movable plate 8. A first motor 9 is mounted on the first movable plate 8, and a cutting disc 10 is fixedly mounted on the output shaft of the first motor 9. The first motor 9 and the cutting disc 10 form a cutting component. When the first motor 9 performs work, its output shaft drives the cutting disc 10 to rotate, thereby achieving cutting. A second arc-shaped plate 11 is connected to the first movable plate 8 via a spring telescopic rod 20. Preferably, the spring telescopic rod 20 includes an outer cylinder mounted on the first movable plate 8, with an inner rod movably inserted inside the outer cylinder. The inner rod is connected to the second arc-shaped plate 11, and a contact spring is provided between the outer cylinder and the inner rod. Both the first arc-shaped plate 6 and the second arc-shaped plate 11 have through-hole clearance grooves. Several rollers 12 are rotatably mounted on both the first arc-shaped plate 6 and the second arc-shaped plate 11. Preferably, the cutting disc 10 can movably pass through... The clearance groove, the rollers 12 on the first arc plate 6 and the second arc plate 11 are arranged in two rows, with the two rows of rollers 12 located on the upper and lower sides of the clearance groove respectively. Under the action of the spring telescopic rod 20, the cutting disc 10 and the second arc plate 11 have a certain distance. In the initial state, the crossbeam 4 is a certain height away from the bearing seat 2. After the steel barrel is fixed on the bearing seat 2, the lifting component 5 drives the crossbeam 4 to descend. At this time, the rollers 12 on the first arc plate 6 overlap with the inner wall of the steel barrel. During cutting, the first motor 9 works to drive the cutting disc 10 to rotate at high speed. Then the first electric push rod 7 works, and its piston end drives the first movable plate 8 to approach the steel barrel. Due to the influence of the spring telescopic rod 20, the rollers 12 on the second arc plate 11 first abut against the outer wall of the steel barrel. However, the spring telescopic rod 20 can be compressed. As the first movable plate 8 continues to move, the cutting disc 10 first moves through the clearance groove on the second arc plate 11, and then contacts the steel barrel to achieve cutting. The specific state is as follows. Figure 7 As shown, at this time, the rollers 12 on the first arc plate 6 and the second arc plate 11 roll and clamp the side wall of the steel drum. The cutting disc 10 first passes through the clearance groove on the second arc plate 11 and then cuts through the side wall of the steel drum. At this time, the bearing seat 2 drives the steel drum to rotate, thereby performing a ring cut. Since the rollers 12 on the first arc plate 6 and the second arc plate 11 are arranged in two rows and roll and clamp the steel drum, without affecting the normal rotation of the steel drum, the rollers 12 on the first arc plate 6 and the second arc plate 11 support the upper and lower sides of the steel drum cutting position (the upper side is the cut ring edge, and the lower layer is the body of the steel drum), so that the upper and lower sides of the actual cutting point have support points, so that the steel drum will not be chipped or deformed due to the cutting stress during the cutting process, thereby ensuring the cutting quality. When the cutting is completed, the first electric push rod 7 drives the first movable plate 8 to reset, which can release the rolling resistance of the steel drum. Then, the fixing part 3 is released, and the steel drum and the cut ring edge can be removed.

[0030] In this scheme, by setting a first arc plate 6 and a second arc plate 11, and constructing relief grooves and rollers 12 on them, during cutting, as the cutting disc 10 slides and cuts, the rollers 12 on the first arc plate 6 and the second arc plate 11 will roll and resist the steel drum. Since the rollers 12 are distributed in two rows, with the cooperation of the relief grooves, the upper and lower sides of the actual cutting point have support points without affecting the cutting. This ensures that the steel drum will not be chipped or deformed due to the cutting stress during the cutting process, thus ensuring the cutting quality.

[0031] like Figure 5 and Figure 6 As shown, a further technical solution of this utility model is disclosed, which allows for flexible adjustment of the position of the first arc-shaped plate 6. A second electric push rod 13 is provided on the crossbeam 4, and a second movable plate 14 is connected to the piston end of the second electric push rod 13. The first arc-shaped plate 6 is fixed on the second movable plate 14. Considering that the inner wall positions of steel barrels of different sizes are different after fixing, since the second arc-shaped plate 11 is connected to the first movable plate 8 through a spring telescopic rod 20, its position can be flexibly adjusted. By setting the second electric push rod 13 and connecting its piston end to the second movable plate 14, the first arc-shaped plate 6 is set on the second movable plate 14, so that the position of the first arc-shaped plate 6 can be flexibly adjusted. In conjunction with the second arc-shaped plate 11, it can effectively provide rolling support for steel barrels of different sizes, thereby improving practicality.

[0032] like Figure 5 and Figure 6 As shown, this utility model discloses a further technical solution to ensure the stability of the first movable plate 8 and the second movable plate 14 after their positions change. A through groove is provided on the crossbeam 4, and the first movable plate 8 and the second movable plate 14 are slidably inserted into the through groove. Since the first movable plate 8 and the second movable plate 14 can be slidably adjusted, and the cutting part itself has a certain weight, it will generate a certain stress when it rotates and cuts. By providing a through groove on the crossbeam 4 and slidably inserting the first movable plate 8 and the second movable plate 14 into the through groove, not only can the two be guided, but the stability of the two after sliding can also be ensured.

[0033] like Figure 7As shown, this utility model discloses a further technical solution for ensuring effective contact between the rollers 12 and the side wall of the steel drum by finely adjusting their position. Several sliding rods 15 are slidably arranged on both the first arc-shaped plate 6 and the second arc-shaped plate 11. Several rollers 12 are rotatably arranged on the sliding rods 15 respectively. Limiting springs 16 connect the sliding rods 15 to the first arc-shaped plate 6 or the second arc-shaped plate 11. Since the rollers 12 are all arc-shaped and distributed on the first arc-shaped plate 6 and the second arc-shaped plate 11, the rollers 12 are rotatably arranged on the first arc-shaped plate 6. A sliding rod 15 is slidably mounted on the slide rod 15, and a roller 12 is rotatably mounted on the slide rod 15. A limiting spring 16 is connected between the slide rod 15 and the first arc plate 6 or the second arc plate 11, so that the position of the roller 12 on the first arc plate 6 and the second arc plate 11 can be finely adjusted. This ensures that when rolling and clamping steel drums of different sizes, the roller 12 on the first arc plate 6 and the second arc plate 11 can effectively roll and abut against the steel drum, ensuring the rolling support area and further improving the cutting effect on the steel drum.

[0034] like Figure 3 and Figure 4 The present invention discloses the specific structure of the fixing component 3 to achieve stable and effective fixing of the steel drum. The fixing component 3 includes several sliders 301. The bearing seat 2 has an internal cavity. The top of the bearing seat 2 is provided with several sliding grooves 302. Preferably, the sliding grooves 302 are arranged in a ring. The longitudinal section of the sliders 301 is I-shaped, which can slide horizontally along the sliding grooves 302, but cannot detach from the sliding grooves 302. The sliders 301 are respectively slidably inserted into the sliding grooves 302. The bottom of the bearing seat 2 is provided with a third electric push rod 303. The piston end of the third electric push rod 303 is connected to a lifting plate 304. The lifting plate 304 is hinged to the sliders 301 with support rods 305. The sliders 301 are provided with support plates 306. When fixing the steel drum, the steel drum is erected on the bearing seat 2, and the support plates 306 are supported. All 06 are located inside the steel drum. At this time, the third electric push rod 303 performs work, and its piston end drives the lifting plate 304 to rise. Since the slider 301 can only slide horizontally, the lifting plate 304 moves vertically. The two are hinged with a support rod 305. Therefore, when the lifting plate 304 rises, several support rods 305 abut against several sliders 301 respectively, so that several sliders 301 slide synchronously away from the center of the bearing seat 2. When several sliders 301 slide away, several support plates 306 abut against the inner wall of the steel drum, thereby fixing the steel drum with internal support. When it is necessary to release the fixation, the third electric push rod 303 drives the lifting plate 304 to fall. Since it adopts synchronous outward expansion or synchronous inward contraction, it can effectively fix the steel drum. At the same time, it can also be coaxially aligned with the bearing seat 2 after the steel drum is fixed, which is convenient for the cutting parts to be circumferentially cut.

[0035] like Figure 3As shown, this utility model discloses a further technical solution for fixing the steel barrel with the inner support of the support plate 306. One side of the support plate 306 is arc-shaped and a rubber pad 17 is provided on the arc-shaped surface. By making one side of the support plate 306 arc-shaped and having the arc-shaped surface in contact with the inner wall of the steel barrel, the contact area is increased. By providing the rubber pad 17, the deformable properties of its material are utilized to not only increase the contact friction between the support plate 306 and the inner wall of the steel barrel and improve the fixing effect of the steel barrel, but also to adapt to steel barrels of different sizes, thereby improving practicality.

[0036] like Figure 4 As shown, this utility model discloses a further technical solution for the stable fixing of the steel barrel by the fixing member 3. The inner wall of the slide groove 302 is provided with grooves 18 on opposite sides. The slider 301 is constructed with two baffles 19, which are slidably inserted into the two grooves 18 respectively. When the steel barrel is cut, dust and debris will be generated during the cutting. The dust and debris will fall downwards. Since the slide groove 302 is connected to the internal cavity of the bearing seat 2, by opening the grooves 18 and setting the baffles 19 on the slider 301 that are inserted into the grooves 18, the slide groove 302 can be blocked without affecting the normal sliding of the slider 301, so as to prevent dust and debris from falling into the bearing seat 2 and affecting the lifting of the lifting plate 304, thus ensuring that the fixing member 3 can effectively and stably fix or release the steel barrel.

[0037] like Figure 2 As shown, the specific structure of the lifting component 5 of this utility model is disclosed to achieve the function of driving the crossbeam 4 to rise and fall. The lifting component 5 includes a column 501 set on the base 1. A through groove is opened through the column 501. A lead screw 502 is rotatably installed on the inner wall of the through groove on opposite sides. One end of the lead screw 502 is connected to a second motor 503 set on the column 501. One end of the crossbeam 4 is slidably inserted into the through groove and threaded onto the lead screw 502. When the second motor 503 does work, its output shaft drives the lead screw 502 to rotate. With the cooperation of the thread and the sliding limit of the through groove, the crossbeam 4 can be driven to rise and fall stably. This can not only adjust the actual cutting height of the cutting disc 10 to ensure the cutting of the steel drum, but also facilitate the removal and unloading of the steel drum.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
