[0070] When a left-right moving mechanism 3331 is adopted, one of the implementation modes is as follows: Example 1: one or more vertically arranged pressure rollers 3332 are arranged on the trimming frame 31, and one or more pressure rollers 3332 are also arranged on the movable part of the left-right moving mechanism 3331. The pressure rollers 3332 on the trimming frame 31 and the pressure rollers 3332 on the left-right moving mechanism 3331 are respectively arranged on the left and right sides of the conveying mechanism. The left-right moving mechanism 3331 drives the pressure rollers 3332 on the movable part of the left-right moving mechanism 3331 to move closer to the pressure rollers 3332 on the trimming frame 31, thereby clamping the first craft from the left and right sides of the first craft to achieve centering positioning of the first craft. At the same time, while clamping, the pressure rollers 3332 can also rotate relative to the first craft, which will not affect the transportation of the first craft in the front-to-back direction, so that the left and right sides of the first craft are accurately positioned during the transportation in the front-to-back direction.

[0071] Preferably, four pressing rollers 3332 are provided, two of which are provided on the trimming frame 31 , and the remaining two are provided on the movable parts of the left and right moving mechanisms 3331 .

[0072] When a left-right motion mechanism 3331 is adopted, another embodiment is, Example 2: The left-right motion mechanism 3331 includes a screw and a pressure roller 3332, and the screw is driven by a motor. The screw is arranged on the trimming frame 31, and the screw can be relatively rotatably connected to the trimming frame 31, for example, the screw is connected to the trimming frame 31 through a bearing seat. The screw extends in the left-right direction, and a left-handed thread and a right-handed thread are provided on the screw, and the left-handed thread and the right-handed thread are respectively arranged on the left and right sides of the side of the screw. Of course, the positions of the left-handed thread and the right-handed thread are interchangeable. The left-handed thread and the preferred thread are respectively provided with a left nut and a right nut, and the left nut and the right nut are respectively matched to connect the screw, and then the left nut and the right nut respectively form a screw nut motion pair with the screw. The motor drives the screw to rotate so that the left nut and the right nut move away from each other or closer to each other. The left nut and the right nut are respectively connected with one or more vertically arranged pressing rollers 3332, and the left nut and the right nut are respectively connected with the pressing rollers 3332 so as to be relatively rotatable, and the rotation axis of the pressing rollers 3332 extends vertically. The pressing rollers 3332 are used to clamp the first craftwork from both sides.

[0073] The user can select different usage modes of the left-right motion mechanism 3331 according to different usage situations. For example, if the user needs to save usage costs and the left-right dimensions of the first craftwork remain substantially unchanged, embodiment 1 can be used. For another example, if the user has high requirements for left-right symmetry and low requirements for the reaction speed of the action movement, embodiment 2 can be used.

[0074] When two left and right motion mechanisms 3331 are used, the two left and right motion mechanisms 3331 are respectively arranged on the trimming frame 31, and the left and right motion mechanisms 3331 include a driving assembly, and the driving assembly drives the pressure rollers 3332 to move in the left and right directions, and each driving assembly drives more than one pressure roller 3332 to move in the left and right directions, and the pressure rollers 3332 extend vertically. Preferably, the left and right motion mechanisms 3331 also include a track extending in the left and right directions and a guide block matching the track, and the pressure rollers 3332 are installed on the guide block, and the guide block and the track are used to limit the movement direction of the pressure rollers 3332.

[0075] Of course, the user can also dispose the left and right movement mechanism 3331 outside the trimming frame 31 according to actual installation needs, for example, the left and right movement mechanism 3331 is fixedly connected to the ground.

[0076] Furthermore, the driving component is any one of an electric push rod, a pneumatic cylinder, and an oil cylinder. In the present embodiment, the left and right motion mechanism 3331 is a pneumatic cylinder.

[0077] In some embodiments, the conveying assembly 32 includes a first conveying belt 321, a supporting roller 322, and a second conveying belt 323. The first conveying belt 321 and the second conveying belt 323 extend in the front-to-back direction respectively. The first conveying belt 321, the supporting roller 322, and the second conveying belt 323 are arranged in sequence in the front-to-back direction. The first conveying belt 321, the second conveying belt 323, and the supporting roller 322 are respectively arranged on the trimming frame 31. The supporting roller 322 and the trimming frame 31 can rotate relative to each other. The axis of the supporting roller 322 extends in the left-right direction. A first gap is provided between the supporting roller 322 and the first conveying belt 321, and a second gap is provided between the supporting roller 322 and the second conveying belt 323. When in use, the first gap or the second gap is used for the first trimming assembly to pass through, so as to play a role of avoidance. The supporting roller 322 is used to support the first craftwork.

[0078] In some embodiments, the first trimming assembly includes: a guide rail 341, a sliding frame 342, a trimming tool 3435 and a first driving mechanism 343; the guide rail 341 is fixed on the trimming frame 31, and the guide rail 341 extends in the left-right direction; the sliding frame 342 is arranged on the guide rail 341, and the sliding frame 342 and the guide rail 341 can slide relative to each other; two groups of the trimming tools 3435 are arranged, and the two groups of the trimming tools 3435 are arranged on the sliding frame 342, and the two groups of the trimming tools 3435 are arranged back to back, and the two groups of the trimming tools 3435 are respectively used to trim the front and rear sides of the first craft; the first driving mechanism 343 is arranged on the trimming frame 31, and the first driving mechanism 343 is used to drive the sliding frame 342 to slide back and forth along the length direction of the guide rail 341.

[0079] When in use, the first driving mechanism 343 is a synchronous belt or a synchronous chain, which drives the sliding frame 342 to move in the left and right directions through belt transmission or chain transmission.

[0080] The sliding frame 342 includes a frame and rollers 3420 arranged on the frame. The frame is arranged in a square frame shape. The frame is sleeved on the guide rail 341. The guide rail 341 is optionally concavely adapted to the frame. There are multiple rollers 3420 on the frame. The rollers 3420 are slidably matched with the upper, lower, front and rear surfaces of the guide rail 341. Optionally, each surface of the guide rail 341 is matched with two rollers 3420. Each roller 3420 is rotatably matched with the frame. Thus, the freedom of movement of the frame is restricted from multiple directions, so that the frame is more stable during the movement along the guide rail 341.

[0081] Each set of trimming tools 3435 includes two blades 3501, and the two blades 3501 are connected to the sliding frame 342 respectively. In some embodiments, the two blades 3501 are connected to the frame respectively. The blades of the two blades 3501 are arranged to face away from the sliding frame 342. The two blades 3501 are arranged to be inclined respectively. Preferably, the two blades 3501 are arranged to be inclined symmetrically to each other, and an angle with an opening upward is formed between the two blades 3501; through the setting of the angle, when the blade 3501 trims the first craftwork, when the inclined blade contacts the cardboard protruding from the first craftwork, the contact area between the blade and the cardboard is smaller, and compared with the blade 3501 arranged vertically, its stress is more concentrated, and the protruding cardboard can be better scraped off to achieve the trimming effect. The two blades 3501 are arranged symmetrically with each other, and the two blades 3501 are arranged side by side in the left-right direction. Therefore, when trimming, scraping can be started from the two corners on the left or right side of the quadrilateral formed by the side of the first craft. For example, scraping can be performed from one of the blades 3501 to the upper left corner of the rear side of the first craft, and the other blade 3501 can be scraped from the lower left corner of the rear side of the first craft.

[0082] Preferably, in the first trimming assembly, the two blades 3501 on the trimming tool 3435 on the front side thereof are arranged in the first gap; and the two blades 3501 on the trimming tool 3435 on the rear side thereof are arranged in the second gap.

[0083] In addition, in order to store the trimming tool 3435 when not in use, a rotating disk 3502 is provided on the shelf, and the rotating disk 3502 is rotatably connected to the shelf so that the rotating disk 3502 and the shelf can rotate relative to each other, and the rotating axis of the rotating disk 3502 extends vertically. The number of the rotating disks 3502 and the blades 3501 corresponds one to one, and each rotating disk 3502 is connected to one blade 3501. A driving cylinder 3503 is provided on the shelf, and the driving cylinder 3503 is used to drive the rotating disk 3502 to rotate.

[0084] Since the trimming tool 3435 on the first trimming assembly is used to trim the front side and the back side of the first craft, the blade 3501 in the first trimming assembly is provided with two sets of trimming tools 3435, the two sets of trimming tools 3435 include four blades 3501, and the four blades 3501 correspond to four turntables 3502, and the two sets of trimming tools 3435 are respectively used to trim the front side and the right side of the first craft. Therefore, in order to save the number of drive cylinders 3503, the front and rear turntables 3502 on the shelf can share one drive cylinder 3503, that is, two drive cylinders 3503 are included in this embodiment. For example, the movable part and the fixed part of the driving cylinder 3503 are respectively hinged to the front and rear turntables 3502, and the front and rear turntables 3502 are driven to rotate at the same time by the extension and retraction of the driving cylinder 3503, thereby realizing the front and rear drive The blade 3501 on the two turntables 3502 is driven to rotate. When the blade 3501 needs to be stored, the two turntables 3502 can drive the blade 3501 to rotate into the shelf through the contraction of the driving cylinder 3503.

[0085] In some embodiments, the second trimming assembly includes a left-right sliding mechanism 8, a tool holder 351 and a trimming tool 3435 arranged on the tool holder 351. The left-right sliding mechanism 8 is arranged on the trimming holder 31, and the tool holder 351 is arranged on the left-right sliding mechanism 8. The left-right sliding mechanism 8 drives the tool holder 351 to slide back and forth along the left-right direction. One or two tool holders 351 are arranged, and the left-right sliding mechanism 8 and the tool holders 351 are arranged in a one-to-one correspondence. When one tool holder 351 is arranged, the tool holder 351 is arranged on the left or right side of the conveying assembly 32. When two tool holders 351 are arranged, the tool holders 351 are arranged on both sides of the left and right sides of the conveying assembly 32.

[0086] The left-right sliding mechanism 8 includes a left-right motion cylinder 82 and a left-right guide rail 81. The tool holder 351 is arranged on the left-right guide rail 81. The left-right guide rail 81 is fixed to the trimming frame 31. The movable part of the left-right motion cylinder 82 is fixedly connected to the tool holder 351, and the fixed part of the left-right motion cylinder 82 is fixedly connected to the trimming frame 31.

[0087] Similarly, in order to realize the function of storing the blade 3501, a turntable 3502 is provided on the tool holder 351. The number of the turntables 3502 corresponds to the blades 3501 one by one. The blades 3501 are all arranged on the turntable 3502. The turntable 3502 can rotate relative to the tool holder 351. The rotation axis of the turntable 3502 extends vertically. A telescopic cylinder 3504 is also provided on the tool holder 351. The movable part of the telescopic cylinder 3504 is hinged to the turntable 3502. The axis of rotation of the hinge part between the telescopic cylinder 3504 and the turntable 3502 is parallel to the rotation axis of the turntable 3502. The fixed part of the telescopic cylinder 3504 is hinged to the tool holder 351. The rotation axes of the two hinges on the telescopic cylinder 3504 are both arranged vertically. The rotating disk 3502 is driven to rotate by the telescopic movement of the telescopic cylinder 3504 , so that the blade 3501 can be rotated. If the blade 3501 needs to be stored, the blade 3501 is rotated into the blade holder 351 .

[0088] Since the structure of the trimming tool 3435 in the first trimming assembly is the same as that of the trimming tool 3435 in the second trimming assembly, their specifications, sizes, and inclination angles of the blades 3501 may be different, but they are both composed of two blades 3501, so the same naming is used.

[0089] In some embodiments, the trimming device 3 further includes a brush assembly, which includes a brush frame 91 and a plurality of bristles, the brush frame 91 being fixed to the trimming frame 31, a channel along the front-to-back direction being formed in the brush frame 91, the bristles being arranged on the inner side wall of the channel, and the channel being used for the first handicraft to pass through. The structure is simple and the arrangement is convenient, and when the first handicraft passes through the channel, the bristles can be used to sweep the dust from the first handicraft.
