Description

Technical Field

[0001] The utility model relates to the technical field of aluminum material processing equipment, in particular to a device for crushing aluminum strip waste edges. Background Art

[0002] During the rolling, finishing, and slitting processes of aluminum sheet and strip, trimming is required to ensure precision. This involves trimming the excess material from the edges of the coil. Since aluminum sheet and strip processing is a continuous process, in actual production, as trimming continues, the trimmed material will produce narrow scrap strips of the same diameter as the coil. However, these strips are too narrow to be easily rolled directly into bundles. To prevent these scrap strips from damaging the coil's surface quality, the scrap strips must be continuously cut into small pieces during the coil rewinding process and promptly removed to ensure smooth and high-quality processing.

[0003] Currently, trimming waste is primarily cut using a shredder. Existing shredders primarily consist of a conveyor mechanism, typically a pair of rollers, and a shredder mechanism, consisting of two paired circular blades with cutting edges for cutting the waste. During operation, the conveyor mechanism transfers the trimming waste between the two discs, which rotate to cut the waste into smaller pieces.

[0004] Although the existing shredder can shred waste strips, the following problems still exist in actual application:

[0005] 1. Since the waste strips are continuously conveyed between the two disc cutters, in order to ensure the continuity of the waste strip shredding action, it is necessary to ensure that the waste strips maintain a certain tension during cutting, so that the waste strips can automatically move forward after being shredded once, so that the next cutting can be carried out smoothly. Therefore, the cutting edges on the disc cutters in the prior art are all set to spiral cutting edges, which results in a complex cutting edge structure on the disc cutters, high processing difficulty and high processing cost.

[0006] 2. Since the cutting edges of the two disc cutters are spiral, the assembly accuracy requirements of the two disc cutters are very high. In addition, material jamming is likely to occur during use, resulting in the inability to discharge waste in a timely manner, affecting the production progress of the entire aluminum plate and strip. Utility Model Content

[0007] The utility model aims to provide a device for cutting aluminum strip waste edges, so as to solve the problems of high cost and low efficiency in the prior art when cutting waste strips into waste materials.

[0008] In order to solve the above problems, the utility model adopts the following technical solution: a device for crushing the edges of aluminum strip waste strips, comprising a fixed knife body and a fixed blade arranged on the fixed knife body, one side of the fixed knife body is rotatably connected to a rotating knife body, and the rotating knife body is provided with a plurality of rotating blades arranged along the circumference of the rotating knife body, the rotating blade is used to cooperate with the fixed blade to cut the waste strips, and a receiving portion for temporarily accommodating the front end of the waste strips is provided between adjacent rotating blades.

[0009] The principle of this solution is as follows: in this application, the rotating blade body is located on one side of the fixed blade body and is arranged to rotate relative to the fixed blade body. When the rotating blade body rotates, the several rotating blades arranged on the rotating blade body rotate in sequence to cooperate with the fixed blade to cut the waste strips. Since there is a time difference when two adjacent rotating blades rotate to the fixed blade, the waste strips are transported forward at a uniform speed during this time difference. Therefore, after the previous rotating blade completes the cutting in sequence, the end of the waste strip continues to be transported forward and enters the accommodating portion arranged between the two adjacent rotating blades. The accommodating portion can temporarily accommodate the part of the waste strip that moves forward until the next rotating blade rotates to the fixed blade and cuts the waste strip again. The part in the accommodating portion can be cut from the waste strip, and the small pieces of waste produced by the cutting are temporarily retained in the accommodating portion. When the rotating blade body rotates and drives the rotating blade to rotate to the direction of the cutting edge, the waste remaining in the accommodating portion automatically falls out of the accommodating groove under the action of its own gravity, so that the accommodating portion can temporarily accommodate the waste produced by the next cutting. Therefore, as the rotating cutter body rotates continuously and the waste strips are continuously conveyed forward, the waste strips can be cut into small pieces continuously and stably, thereby achieving continuous shredding of the waste strips.

[0010] The beneficial effects of this program are:

[0011] 1. It can effectively reduce the cost of waste shredding: Compared with the structure of the existing shredder that requires a spiral blade, the spiral blade has a complex structure, high processing cost and very high assembly precision requirements. In this application, because the accommodating portion is provided to temporarily accommodate the waste to be shredded, it is only necessary to set the rotating blade and the fixed blade as straight blades to stably complete the waste shredding operation. The entire structure is simpler, the corresponding cost is greatly reduced, and the rotation precision requirements for the fixed blade and the rotating blade are significantly reduced.

[0012] 2. The waste strip shredding process can be carried out efficiently and stably: In the present application, since the accommodating portion is provided to temporarily store the waste generated by shredding, it is not necessary to apply tension to the waste strips during the waste strip transmission process. Therefore, the fixed blade and the rotating blade can be set to a straight blade structure, which is completed instantly when cutting the waste strips, and the waste generated by cutting is only temporarily stored in the accommodating portion. When the rotating blade rotates to a vertical downward position, the waste can automatically fall out of the accommodating groove under the action of its own gravity, so that the cutting of the waste strips is carried out efficiently and stably, effectively ensuring the efficient production of aluminum strip plates.

[0013] Preferably, as an improvement, the accommodating portion includes a curling groove arranged between two adjacent rotating blades, the front rotating blade and the rear rotating blade, the curling groove is smoothly connected to the back side of the front rotating blade, and a accommodating space for temporarily accommodating waste strips is formed between the curling groove and the rear rotating blade.

[0014] In this solution, the accommodating portion is a curling groove arranged between two adjacent rotating blades. The curling groove is used as a accommodating space for continuously conveying waste strips forward and as a temporary storage space for temporarily storing shredded waste. The back side of the front rotating blade of the curling groove is smoothly connected, so that after the front rotating blade cuts off the waste strip, the newly generated end of the waste strip can be smoothly conveyed to the accommodating space between the front rotating blade and the rear rotating blade, so that when the rear rotating blade rotates to the fixed blade, the waste strip can be smoothly cut to form waste. The structure is simple and the accommodating effect is stable.

[0015] Preferably, as an improvement, a frame is provided on one side of the fixed blade body, a movable seat is movably connected to the frame, and the rotating blade body is rotatably connected to the movable seat.

[0016] In this solution, the movable seat is movably connected to the frame, and the rotating knife body is rotatably connected to the movable seat. By adjusting the different positions of the movable frame, the shearing gap when the rotating blade is rotated to cooperate with the fixed blade can be changed. Not only can the rotating blade be adjusted to the optimal shearing effect state, but also waste strips of different thicknesses can be cut by adjusting the position of the rotating blade, which has a wider range of applications.

[0017] Preferably, as an improvement, the frame is provided with an auxiliary discharge mechanism for assisting in discharging the waste materials that have been broken into pieces in the curling groove.

[0018] In this solution, an auxiliary discharge mechanism is used to discharge the waste in the curling groove, so that the entire device can operate continuously and stably.

[0019] Preferably, as an improvement, the auxiliary exhaust mechanism includes a high-pressure air pipe provided on one side of the rotating blade body, and the high-pressure air pipe is provided in a direction in which the air can be blown toward the accommodating portion.

[0020] In this solution, a high-speed air flow is blown toward the receiving portion through a high-pressure air pipe, and the air flow is used to blow the waste material that has been cut off in the receiving portion out of the receiving portion. The high-pressure air pipe has a simple structure and can conveniently discharge the waste material. It is very convenient to set up and has low cost.

[0021] Preferably, as an improvement, the high-pressure air pipe includes a forward high-pressure air pipe and / or an inclined high-pressure air pipe, wherein the forward high-pressure air pipe is perpendicular to the side of the rotating blade body, and the inclined high-pressure air pipe is inclined at an angle to the side of the rotating blade body.

[0022] In this solution, the high-pressure air pipe can be a forward high-pressure air pipe, and the high-pressure air flow blown out by the forward high-pressure air pipe is perpendicular to the side of the rotating blade body, so that the waste material in the accommodating part can be blown out, thereby achieving the purpose of auxiliary waste discharge; in addition, the high-pressure air pipe can also be an inclined high-pressure air pipe set at an angle, and the inclined high-pressure air pipe blows an inclined air flow toward the accommodating part, which can also effectively blow out the waste material in the accommodating part, or the high-pressure air pipe includes both a forward high-pressure air pipe and an inclined high-pressure air pipe, which can also achieve the purpose of auxiliary waste discharge.

[0023] Preferably, as an improvement, a drainage groove cooperating with the inclined high-pressure air pipe is opened on the side surface of the rotating blade body, and the drainage groove is communicated with the accommodating portion.

[0024] In this solution, when an inclined high-pressure air pipe is set up, a drainage groove is opened on the side of the rotating blade body so that the gas blown out of the inclined high-pressure air pipe can more conveniently enter and exit the accommodating part through the drainage groove, thereby more conveniently blowing out the waste in the accommodating part, thereby achieving a better auxiliary waste discharge effect.

[0025] Preferably, as an improvement, the discharge end of the fixed blade is tilted upward, a limit block is provided above the fixed blade body, and a feeding gap for the waste strips to pass through is provided between the limit block and the fixed blade body.

[0026] In this solution, a limit block is used to limit the waste strips when they are conveyed to the fixed blade, thereby improving the stability of the waste strips during the shredding process. At the same time, the discharge end of the fixed blade is tilted upward. On the one hand, the fixed blade tilted upward can more conveniently cooperate with the rotating blade to complete the cutting of the waste strips. On the other hand, by tilting the discharge end of the fixed blade upward, after the previous rotating blade completes the cutting operation, when the waste strip continues to be conveyed forward, the front end of the waste strip slides out of the discharge end of the fixed blade at an angle upward, so that the front end of the waste strip can easily slide into the next receiving portion, thereby improving the stability of the waste strips during the shredding process.

[0027] Preferably, as an improvement, a receiving box is provided below the rotating cutter body.

[0028] In this solution, a receiving box is used to collect the waste generated by shredding, which is convenient for subsequent unified processing.

[0029] Preferably, as an improvement, a baffle cooperating with the forward high-pressure air pipe is fixedly connected to the receiving box, and a waste guide plate is connected between the top surface of the receiving box and the fixed cutter body.

[0030] In this solution, a baffle is set to block the waste that may splash during the cutting process, and a waste guide is used to guide the falling waste so that the waste can fall accurately into the receiving box, achieving better waste collection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is further described in detail through specific implementation methods:

[0037] The figure marks in the drawings of the specification include: fixed blade 1, fixed blade 101, frame 2, rotating blade 3, rotating blade 301, drainage groove 302, drive motor 4, connecting shaft 5, limit block 6, waste strip 7, waste 701, curling groove 8, receiving box 9, waste guide plate 10, movable seat 11, inclined high-pressure air pipe 12.

[0038] Example 1

[0039] This embodiment is as shown in the attached Figure 1 and Figure 2As shown: A device for shredding waste strips of aluminum strips, comprising a fixed blade body 1 and a fixed blade 101 arranged at the top right side of the fixed blade body 1, a frame 2 is provided on the right side of the fixed blade body 1, a rotating blade body 3 is rotatably connected to the frame 2, and a plurality of rotating blades 301 uniformly arranged along the circumference of the rotating blade body 3 are integrally formed on the rotating blade body 3. Specifically, in this embodiment, a driving motor 4 is fixedly connected to the frame 2 by screws, a connecting shaft 5 is fixed to the driving motor 4 by screws, the connecting shaft 5 and the frame 2 are rotatably connected by a bearing, and the rotating blade 3 is fixedly connected to the connecting shaft 5 by a flat key, and the driving motor 4 is used to drive the rotating blade 301 to rotate. In addition, as Figure 1 As shown, in this embodiment, the number of rotating blades 301 on the rotating blade body 3 is seven. In other embodiments other than this embodiment, the number of rotating blades 301 can be set to other numbers, and the rotating blades 301 can be processed and manufactured separately, and then fixedly connected to the rotating blade body 3 with screws, which will not be repeated here.

[0040] like Figure 1 As shown, the discharge end of the fixed blade 101 is tilted to the upper right, and a limit block 6 located above the fixed blade body 1 is fixedly connected to the frame 2. The limit block 6 can be made of wear-resistant polyurethane material. A feeding gap is provided between the limit block 6 and the fixed blade body 1 for conveying the waste strips 7 to the right in the prior art. The feeding gap is used to limit the conveying of the waste strips 7, so that the feeding of the waste strips 7 is more accurate and stable.

[0041] Combine Figure 1 and Figure 2 A storage portion for temporarily accommodating the waste strips 7 is provided between two adjacent rotating blades 301. The storage portion includes a curling groove 8 disposed between the two adjacent rotating blades 301, the front rotating blade 301, and the rear rotating blade 301. The curling groove 8 and the rear rotating blade 301 define a storage space of a certain length for temporarily accommodating the front end of the waste strips 7. When the rotating blade 3 rotates until the front rotating blade 301 cuts the waste strips 7, generating a section of waste material 701, the waste material 701 can be temporarily retained in the front curling groove 8. The curling groove 8 corresponding to the rear rotating blade 301 is smoothly connected to the back of the front rotating blade 301, allowing the end of the waste strips 7 to slide smoothly into the rear curling groove 8, thereby ensuring continuous and stable shredding of the waste strips 7.

[0042] like Figure 1As shown, a receiving box 9 with an open upper end is provided below the rotating blade 3, and the receiving box 9 is used to collect the shredded waste 701 so that the waste 701 can be processed uniformly later; at the same time, in order to make the waste 701 fall into the receiving box 9 more accurately, a baffle and a waste guide plate 10 (the baffle is not shown) are fixedly connected by screws in this embodiment, and the baffle is used to prevent the waste 701 from scattering everywhere. The waste guide plate 10 is tilted and the high end of the waste guide plate 10 is located below the fixed blade 101, and the low end of the waste guide plate 10 is located at the upper opening position of the receiving box 9.

[0043] The specific implementation process is as follows:

[0044] In this embodiment, the waste strips 7 generated during the processing of the aluminum plate and strip are continuously and uniformly fed into the feeding gap from the left end of the fixed blade body 1. The feeding gap transmits and limits the waste strips 7, so that the front end of the waste strips 7 slides out of the right side of the fixed blade body 1 from the discharge end of the fixed blade 101. At the same time, the driving motor 4 is used to drive the connecting shaft 5 to rotate, and the connecting shaft 5 drives the rotating blade 3 and the rotating blade 301 on the rotating blade body 3 to rotate synchronously. When the front end of the waste strip 7 is transmitted to the right and enters one of the curling grooves 8, as the curling groove 8 corresponds to the rotating blade 301 behind it, it rotates to a state of cooperation with the fixed blade 101, so that The front end of the waste strip 7 is cut off by the rotating blade 301 to produce a piece of waste 701, and the generated waste 701 is temporarily left in the curling groove 8. After the front end of the waste strip 7 is cut off, as the waste strip 7 continues to be transported forward, the front end of the waste strip 7 is transported to the next curling groove 8, and then when the next rotating blade 301 rotates to cooperate with the fixed blade 101 to cut the waste strip 7, new waste 701 is generated and located in the curling groove 8. The above cycle is repeated, so that the waste strip 7 can be continuously cut as the rotating blade body 3 rotates, and the waste strip 7 is stably and continuously cut into small pieces of waste 701.

[0045] When the front end of the waste strip 7 is cut off by the rotating blade 301 and the waste 701 is left in the curling groove 8, as the rotating blade 3 rotates, when the curling groove 8 rotates to a state with the opening downward, the waste 701 left in the curling groove 8 falls out of the curling groove 8 under the action of its own gravity, and falls downward onto the waste guide plate 10, and finally slides along the waste guide plate 10 and falls into the receiving box 9.

[0046] Example 2

[0047] The difference between the second embodiment and the first embodiment is that in the first embodiment, the driving motor 4 is fixedly connected to the frame 2, so that the position of the rotating blade 3 relative to the frame 2 and the fixed blade 1 is fixed. Figure 3As shown, in this embodiment, a movable seat 11 is laterally movably connected to the frame 2, and the drive motor 4 is fixedly connected to the movable seat 11 by screws. The rotating blade body 3 is fixedly connected to the drive motor 4 and is rotatably connected to the movable seat 11 by a bearing. As for the specific method of the laterally movably connected movable seat 11, a laterally arranged waist-shaped groove can be provided on the frame 2, and a fixing hole that matches the waist-shaped groove can be provided on the movable seat 11. After the position of the movable seat 11 is laterally adjusted, the movable seat 11 can be re-fixed to the frame 2 by screws passing through the waist-shaped hole and then locking it with the fixing hole. The fixed method or other movable connection methods of the movable seat 11 will not be detailed here.

[0048] In this embodiment, since the movable seat 11 is laterally movably connected to the frame 2, the distance between the rotating blade 3 and the fixed blade 1 can be adjusted. Not only can the cutting gap between the rotating blade 301 and the fixed blade 101 be fine-tuned when actually cutting the waste strips 7, thereby achieving a better waste strip 7 cutting effect, but the cutting gap between the rotating blade 301 and the fixed blade 101 can also be adjusted to a larger size, so that the rotating blade 301 can smoothly cut waste strips 7 of different thicknesses, and has a wider range of applications.

[0049] Example 3

[0050] The difference between the third embodiment and the first embodiment is that: Figure 4 As shown, in this embodiment, an auxiliary discharge mechanism is provided on the frame 2 for assisting in discharging the scrap 701 that has been broken in the curling groove 8. The auxiliary discharge mechanism includes a high-pressure air pipe provided on one side of the rotating blade 3, and the high-pressure air pipe is provided in a direction that can blow toward the receiving portion. Figure 5 , wherein the high-pressure air pipe includes a forward high-pressure air pipe and / or an inclined high-pressure air pipe 12, the forward high-pressure air pipe is perpendicular to the side of the rotating blade body 3, and the inclined high-pressure air pipe 12 is inclined to form an angle with the side of the rotating blade body 3. In this embodiment, only the setting method of the inclined high-pressure air pipe 12 is shown. In other embodiments other than this embodiment, the forward high-pressure air pipe can be set alone, or the forward high-pressure air pipe and the inclined high-pressure air pipe 12 can be combined. They are not shown one by one here.

[0051] Combine Figure 4 and Figure 5The inclined high-pressure air pipe 12 and the side of the rotating blade body 3 are arranged at an angle to each other, and a drainage groove 302 cooperating with the inclined high-pressure air pipe 12 is provided on the side of the rotating blade body 3, that is, the setting direction of the drainage groove 302 is the same as the direction of the gas blown out by the inclined high-pressure air pipe 12, and the drainage groove 302 is connected with the curling groove 8, so that the high-pressure gas blown out of the inclined high-pressure air pipe 12 can enter the curling groove 8 through the drainage groove 302, thereby conveniently blowing the waste material 701 in the curling groove 8 out of the curling groove 8, so that the curling groove 8 can be temporarily stored for the next waste material 701.

[0052] In this embodiment, by providing an auxiliary discharge mechanism, the waste material 701 temporarily stored in the curling groove 8 can be quickly and completely discharged out of the curling groove 8, so that the scrapping operation of the waste strips 7 can be carried out continuously and stably.

[0053] The above description is merely an embodiment of the present invention, and the commonly known specific technical solutions and / or features of the solution are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be considered as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed in this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
