In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0057] This embodiment discloses a cutting device.

[0058] Reference Figures 1 to 3 The cutting device comprises a frame 1, a conveying plate 2, a cutting mechanism 3, a feeding assembly 4 and a feeding mechanism. The conveying plate 2 is arranged on the frame 1 and extends along the conveying direction of the product to support the product; the cutting mechanism 3 is arranged on the frame 1 and has a cutting knife 31, the conveying plate 2 has a cutting slit corresponding to the cutting knife 31, and the cutting mechanism 3 can drive the cutting knife 31 to be inserted into the cutting slit to cut the product; the feeding assembly 4 is arranged on one side of the cutting mechanism 3 to convey the product to the cutting mechanism 3; the feeding mechanism is arranged on the other side of the cutting mechanism 3 and is used to send the product cut by the cutting mechanism 3 away.

[0059] Specifically, the frame 1 includes a support frame 11 and a bottom plate 12 disposed on the support frame 11. The support frame 11 can be fixed on the corresponding structure, and the fixing method can be any one of clamping, bolt connection, welding, etc. The conveying plate 2 is arranged above the bottom plate 12. The conveying plate 2 may include a plurality of plate-like structures, and two adjacent plate-like structures form a certain gap, which serves as a cutting seam when corresponding to the cutting mechanism 3. The top wall of the conveying plate 2 may be polished to form a smooth surface to ensure that the product will not be damaged by friction with the conveying plate 2 during the conveying process.

[0060] When cutting the product, the feeding component 4 sends the product to the cutting mechanism 3, and ensures that the cutting part of the product is just at the cutting seam. Then the cutting mechanism 3 can drive the cutting knife 31 to reciprocate up and down. When the cutting knife 31 moves down and inserts into the cutting seam, the cutting of the product can be completed. The unloading mechanism can quickly send the finished product away, so that the feeding component 4 can continue to feed, ensuring that the cutting operation continues. Both the feeding component 4 and the unloading mechanism can be implemented by a manipulator, a roller, or a belt transmission, and can be designed according to the actual installation space and manufacturing cost.

[0061] When cutting the product, the feeding assembly 4 is used to deliver the product to the conveying plate 2. When the cutting part of the product is facing the cutting seam, the cutting mechanism 3 controls the cutting knife 31 to move down and insert into the cutting seam to complete the cutting of the product. The finished product is directly sent away by the unloading mechanism, and the feeding assembly 4 can continue to convey the product to ensure that the cutting operation can be carried out continuously. In this way, when the cutting device is used, the cutting operation can be continuously carried out on the product through the cooperation of the cutting mechanism 3, the feeding assembly 4 and the unloading mechanism to ensure high operation efficiency. During the cutting operation, because the cutting knife 31 is inserted into the cutting seam and pulled out from the cutting seam only by the up and down reciprocating movement of the cutting knife 31, the cutting of the product can be completed. Therefore, when the whole device is running, it only needs to control the moving speed of the cutting knife 31 according to the conveying rate of the product and the distance between two adjacent cutting parts. The overall control difficulty is relatively small, and the control logic is relatively simple, which can not only effectively reduce the manufacturing difficulty of the whole device, but also reduce the difficulty of maintenance and maintenance of the equipment in the later stage.

[0062] Optionally, the unloading mechanism includes a first conveying assembly 5 and a second conveying assembly 6. The first conveying assembly 5 is arranged on the side of the cutting mechanism 3 away from the loading assembly 4, and drives the cut product to move away from the cutting mechanism 3 at a first speed; the second conveying assembly 6 is arranged on the side of the first conveying assembly 5 away from the cutting mechanism 3, and drives the product conveyed by the first conveying assembly 5 at a second speed. The first speed is greater than the second speed.

[0063] Specifically, the first conveying assembly 5 and the second conveying assembly 6 are spaced apart along the conveying direction of the product, and the first conveying assembly 5 is closer to the cutting mechanism 3. When the cutting part of the product corresponds to the cutting seam, the product will contact the first conveying assembly 5 at the same time. Then, when the product is cut, the first conveying assembly 5 can directly convey the product, and convey it at a faster first speed, so that the product moves quickly to the second conveying assembly 6. The second conveying assembly 6 conveys the product at a slower second speed, so that the product can be slowly conveyed to the next step. The specific values ​​of the first speed and the second speed can be designed according to the actual application scenario, and the utility model does not limit this.

[0064] By delivering the finished product to the second conveying component 6 at a faster first speed, and using the second conveying component 6 to slowly deliver the product to the next process at a slower second speed, the entire product can be quickly sent away after the cutting is completed, ensuring that the finished product is safely delivered to the next process, and the loading component 4 can also quickly deliver new products at the same time.

[0065] Reference Figure 3 and Figure 4 Optionally, the cutting device further comprises a dust removal assembly 7. The dust removal assembly 7 is arranged on the conveying plate 2 and has a dust removal cavity, and the conveying plate 2 has a first gap 21 communicating with the dust removal cavity. A plurality of dust removal assemblies 7 are distributed at intervals.

[0066] Specifically, the first gap 21 can be formed by splicing multiple plate-like structures of the conveying plate 2, and the side of the plate-like structure can be flat or curved, so that the first gap 21 can be a long straight gap or a curved gap. Along the conveying direction of the product, multiple dust removal components 7 are distributed at intervals, and each first gap 21 corresponds to only one dust removal component 7. In this embodiment, three dust removal components 7 and three first gaps 21 are provided. In other embodiments, the number of dust removal components 7 and first gaps 21 can be designed according to the actual distance that the product needs to be conveyed.

[0067] The dust removal component 7 can be a shell structure arranged on the lower side of the conveying plate 2, and its interior is hollow as a dust removal chamber, and its top is open and fits with the bottom wall of the conveying plate 2 to ensure that the dust removal chamber is connected to the first gap 21. Dust removal pipelines can be connected at both ends of the dust removal chamber to extract dust in time. The dust removal component 7 can also be a shell structure arranged on both the upper and lower sides of the conveying plate 2. Thereby, a dust removal chamber is formed on both the upper and lower sides of the conveying plate 2, and a certain gap is reserved between the upper shell structure and the conveying plate 2 to allow the product to pass smoothly. The specific structure of the dust removal component 7 can be determined according to the actual dust removal effect.

[0068] By setting up the dust removal component 7, when the product is conveyed along the conveying plate 2, when the product passes through the first gap 21, the dust on the surface of the product can fall into the first gap 21. After passing through the first gap 21, the dust will enter the dust removal chamber for collection and then be extracted by the dust removal pipeline to reduce the possibility of dust flying.

[0069] Optionally, the first slit 21 extends in a curved manner.

[0070] Specifically, the end faces of the multiple plate-like structures of the conveying plate 2 are curved, so that the first slit 21 is bent and extended, and the specific bending amplitude and shape can be designed according to the size and shape of the actual conveying plate 2. In this embodiment, among the multiple plate-like structures of the conveying plate 2, the end faces of the plate-like structures used to form the first slit 21 are tooth-shaped, and the tooth-shaped end faces of two adjacent plate-like structures can be plugged and matched with each other to form the above-mentioned first slit 21, so that the first slit 21 is connected in sequence in the form of multiple "W" on the horizontal projection plane.

[0071] By bending and extending the first slit 21, the communicating area between the first slit 21 and the dust removal chamber can be increased without changing the width of the first slit 21, which is conducive to dust entering the dust removal chamber through the first slit 21. In addition, in order to improve the dust removal effect, the dust removal chamber can be in a negative pressure state, and the bent and extended first slit 21 can ensure that the product is evenly stressed when absorbing dust on the surface of the product, thereby improving the dust removal effect while ensuring the safety of dust removal and reducing the deformation of the product during the dust removal process.

[0072] Optionally, the dust removal assembly 7 includes a first dust removal shell 71. The first dust removal shell 71 is disposed on the bottom wall of the conveying plate 2, and the top wall of the first dust removal shell 71 is open and communicates with the first slit 21 accordingly.

[0073] Specifically, the first dust removal shell 71 has a V-shaped longitudinal section and an arc-shaped bottom, and its opening is fixed to the bottom wall of the conveying plate 2 by fasteners such as bolts, and the opening covers the first gap 21. A connecting pipe is provided on the end surface of the first dust removal shell 71, and a dust extraction device is connected through the connecting pipe to form a negative pressure chamber in the dust removal chamber.

[0074] By setting the first dust removal shell 71, a dust removal chamber can be formed on the lower side of the conveying plate 2, so that when the product passes through the first gap 21, the dust on the surface of the product can smoothly pass through the first gap 21 and fall into the dust removal chamber, and the shape structure of the first dust removal shell 71 will not affect the conveying of the product.

[0075] Optionally, the dust removal assembly 7 includes a dust removal plate 72 and a second dust removal shell 73. The dust removal plate 72 is arranged on the frame 1 and corresponds to the first gap 21, a conveying gap for the product to pass through is provided between the dust removal plate 72 and the conveying plate 2, and the dust removal plate 72 has a second gap 721 connected to the conveying gap; the second dust removal shell 73 is arranged on the dust removal plate 72 and covers the second gap 721.

[0076] Specifically, a dust removal plate 72 is arranged above the conveying plate 2, and the extension direction of the dust removal plate 72 is perpendicular to the conveying direction of the product. The dust removal plate 72 is directly opposite to the first slit 21, and maintains a certain distance from the conveying plate 2 to form a conveying slit. A second slit 721 is formed through the dust removal plate 72, and the second dust removal shell 73 is fixed on the top wall of the dust removal plate 72. The structure of the second dust removal shell 73 is exactly the same as that of the first dust removal shell 71, and the shape of the second slit 721 is exactly the same as that of the first slit 21, and the utility model will not be repeated here.

[0077] By setting the dust removal plate 72 and the second dust removal shell 73, a conveying gap is formed above the conveying plate 2. When the product passes through the conveying gap, the dust on both sides of the product can enter the first dust removal shell 71 and the second dust removal shell 73 through the first gap 21 and the second gap 721 respectively, thereby effectively improving the dust removal effect on the product.

[0078] Reference Figure 5 Optionally, the dust removal plate 72 is slidably connected to the frame 1 to adjust the size of the conveying gap, and the dust removal assembly 7 further includes a locking block 75. The locking block 75 is arranged on the dust removal plate 72 and has an adjustment hole 751. The frame 1 is provided with a plurality of locking holes corresponding to and connected to the adjustment holes 751 at intervals, and a locking piece capable of connecting to any of the adjustment holes 751 is penetrated in the adjustment hole 751.

[0079] Specifically, the dust removal plate 72 is slidably connected to the frame 1 in the vertical direction, and locking blocks 75 are fixedly connected to both ends of the dust removal plate 72, and two locking blocks 75 are set at each end. The locking blocks 75 and the dust removal plate 72 can be fixed together by welding or bolting. The locking block 75 is in a long strip shape and extends in the vertical direction. An adjustment hole 751 is opened through the locking block 75. The adjustment hole 751 is a waist-shaped hole and extends in the vertical direction. An inverted U-shaped mounting frame 13 is set on the bottom plate 12 of the frame 1. The vertical arm of the mounting frame 13 is fixed on the bottom plate 12, and a locking hole is opened through the vertical arm of the mounting frame 13.

[0080] The locking member can be a bolt, the locking hole can be a threaded hole, and the adjustment hole 751 can be a countersunk hole. By tightening the locking member, the locking block 75 can be fixed on the mounting frame 13, and by loosening the locking member, the locking block 75 can be pulled to slide in the vertical direction. The locking member can also be other structures that can achieve locking of the locking block 75, and the utility model does not limit the specific composition of the locking member.

[0081] By slidingly connecting the dust removal plate 72 to the frame 1, the size of the conveying gap can be flexibly adjusted, which is beneficial for products of different thicknesses to pass through the conveying gap smoothly, thereby effectively improving the adaptability to different types of products.

[0082] Optionally, the conveying plate 2 may also be slidably connected to the mounting frame 13 , and the locking block 75 is also provided on the conveying plate 2 to form a locking function, so as to flexibly adjust the relative height of the conveying plate 2 .

[0083] Reference Figure 2 and Figure 3 Optionally, the feeding assembly 4 includes a driving roller 41, a feeding drive 42, a driven roller 43, a dust cover 44 and a brush 45. The driving roller 41 is rotatably connected to the frame 1; the feeding drive 42 is connected to the driving roller 41 to drive the driving roller 41 to rotate; the driven roller 43 is arranged opposite to the driving roller 41 and forms a gap for conveying products with the driving roller 41; the dust cover 44 is arranged on the frame 1 and located at the lower side of the driving roller 41, and the driving roller 41 partially extends into the dust cover 44; the brush 45 is arranged in the dust cover 44 and contacts the driving roller 41 extending into the dust cover 44.

[0084] Specifically, a set of mounting frames 13 are arranged on the frame 1 corresponding to the feeding assembly 4, the first conveying assembly 5 and the second conveying assembly 6. The active roller 41 is rotatably connected to the side wall of the mounting frame 13, and the feeding driving member 42 adopts a motor, which is connected to the end wall of the active roller 41 through a reducer to drive the active roller 41 to rotate. A driven roller 43 is arranged above the active roller 41, and the two ends of the driven roller 43 are slidably connected to the mounting frame 13 through a slide rail and a slider, and a lifting cylinder 46 is arranged on the mounting frame 13 to drive the driven roller 43 to move up and down. A dust cover 44 is arranged on the lower side of the active roller 41, and the inside of the dust cover 44 is hollow as a dust collecting chamber, and the upper part of the dust cover 44 is opened for the lower side of the active roller 41 to extend into, and a brush 45 is arranged in the dust collecting chamber, and the brush 45 is arranged opposite to the active roller 41 and the bristles of the brush 45 abut against the outer surface of the active roller 41. The structures of the first conveying assembly 5 and the second conveying assembly 6 are the same as that of the feeding assembly 4 , and the three differ only in positions and local dimensions. The present invention will not elaborate on the structures of the first conveying assembly 5 and the second conveying assembly 6 .

[0085] When conveying the product, the driven roller 43 is first lifted by the lifting cylinder 46. When the product enters between the active roller 41 and the driven roller 43, the lifting cylinder 46 drives the driven roller 43 to move downward to fit the product. The feeding drive 42 starts to drive the active roller 41 to rotate, thereby driving the product to move. During the rotation of the active roller 41, the brush 45 continuously contacts the active roller 41 to retain the dust adhered to the surface of the active roller 41 in the dust collecting chamber, thereby effectively reducing the dust adhered to the surface of the active roller 41.

[0086] Reference Figure 3 and Figure 6Optionally, the cutting mechanism 3 includes a cutting drive member 32 and a dust collecting shell 33. The cutting drive member 32 is disposed on the frame 1 and connected to the cutting knife 31 to drive the cutting knife 31 to reciprocate; the dust collecting shell 33 is disposed on the lower side of the conveying plate 2 and communicated with the cutting seam.

[0087] Specifically, the cutting drive member 32 may be a motor, which is fixed on the mounting frame 13, and the output end of the motor is connected to the cam transmission mechanism 34, and the cam transmission mechanism 34 is connected to the cutting knife 31, so as to realize the reciprocating movement of the cutting knife 31. The specific structure of the cam transmission mechanism 34 can be designed according to the actual installation space, and it only needs to realize the stable drive of the cutting knife 31.

[0088] The dust collecting shell 33 is arranged below the conveying plate 2, and its top wall has an opening corresponding to the cutting seam. The width of the opening decreases along the vertical direction so that the side of the opening is inclined, which has a better guiding effect on the dust. An inclined surface opposite to the inclination direction of the side of the opening can be arranged on the side wall of the dust collecting chamber so that the communication channel between the opening and the dust collecting chamber is bent, thereby reducing the possibility of dust floating out of the opening.

[0089] When cutting the product, the cutting drive 32 is started, and the cutting drive 32 drives the cutting knife 31 to move downward so that the cutting knife 31 is inserted into the cutting seam, and the cutting is completed. The dust generated during cutting at the cutting seam falls into the dust collecting chamber in the dust collecting shell 33, thereby effectively reducing the possibility of dust flying.

[0090] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
