Technical Field

[0001] The utility model relates to the technical field of printing, and particularly relates to an inner hole waste removing machine. Background Art

[0002] The inner hole waste removing machine is used to clean the waste paper in the inner hole generated after die-cutting the printed matter. The punch penetrates into the inner hole to cut off the waste paper in the inner hole. A Chinese patent with the publication number CN 219726539 U discloses an inner hole waste removing machine. A control box is arranged at the top end of the inner hole waste removing machine body. The bottom end of the control box is provided with a stamping plate through an electric push rod. Fixed components are symmetrically arranged inside the stamping plate. A stamping knife is snap-fitted and installed at the bottom end of the fixed component. A latex pad is arranged at the bottom end of the stamping plate. When the stamping plate moves downward, the latex pad and the stamping knife simultaneously contact the paper placed on the topmost layer of the inner hole waste removing machine body, and the stamping knife penetrates into the inner hole for waste removal.

[0003] However, when the inner hole waste removing machine of the above solution contacts the paper with the stamping knife and applies pressure to penetrate into the inner hole, the edge of the paper will warp under the action of the pressure, resulting in the deviation of the position of the stamping knife in the inner hole and unable to accurately remove waste. It will also cause the deformation of the paper. At the same time, during the continuous movement of the stamping knife in the inner hole, the waste paper gradually falls off, resulting in debris remaining in the inner hole, which is not easy to clean.

[0037] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0038] See Figure 1 , which shows an example of the inner hole waste cleaning machine provided by the present utility model.

[0039] As can be seen from the figure, the inner hole waste cleaning machine of this example mainly includes a machine body 1 and a control mechanism 2, a stamping mechanism 3 and a fixing mechanism 4 provided on the machine body 1. The fixing mechanism 4 is used to fix the printed matter, and the control mechanism 2 can drive the stamping mechanism 3 to move and penetrate into the inner hole of the printed matter for waste cleaning.

[0040] Among them, the stamping mechanism 3 includes a stamping plate 31 and a blowing and fixing device 32 that can be set at any position on the stamping plate 31. The blowing and fixing device 32 is configured to be able to connect to the punch 33 and also blow air in the moving direction of the punch 33, so that the stamping mechanism 3 moves towards the fixing mechanism 4. When the punch 33 penetrates into the inner hole of the printed matter, the blowing and fixing device 32 can blow air into the inner hole to blow out the debris generated by waste cleaning from the inner hole, facilitating the cleaning of the debris in the inner hole; the fixing mechanism 4 includes a fixed slide rail 41 and an adjustable slide rail 42 that can axially move on the fixed slide rail 41. The adjustable slide rail 42 is composed of a first section of slide rail 421 and a second section of slide rail 422. The first section of slide rail 421 and the second section of slide rail 422 can be butted into a vertical state and can also be distributed at an angle, so that the adjustable slide rail 42 can be adjusted into various shapes. The cooperation of multiple adjustable slide rails 42 at different positions and shapes on the fixed slide rail 41 enables the fixing mechanism 4 to adapt to printed matters of various structural shapes. The fixing mechanism 4 further includes a pressing device 43 provided on the adjustable slide rail 42. The pressing device 43 is configured to be able to press the circumferential surface and the top surface of the printed matter, so that the printed matter is not easily warped and deformed under the pressure generated when the punch 33 penetrates into the inner hole.

[0041] Specifically, in combination with Figure 2 and Figure 3 , a number of placement holes 311 are distributed on the stamping plate 31 of the stamping mechanism 3, and threads are provided on the inner surface of each placement hole 311, so that the blowing and fixing device 32 can be set in the placement hole 311 at any position and connected to the placement hole 311 through the threads on the outer surface of the blowing and fixing device 32. Further, the punch 33 is detachably provided on one side of the blowing and fixing device 32, so that the punch 33 can be set at any position on the stamping plate 31 through the blowing and fixing device 32, thereby enabling the punch 33 to adjust its position to correspond to the inner hole of the printed matter on the fixing mechanism 4.

[0042] At the same time, the punch 33 can be detached from the blowing and fixing device 32 and replaced with punches of different structural shapes, so that the punch 33 is adapted to the inner hole for precise waste cleaning of the inner hole.

[0043] Further, in combination with Figure 1 and Figure 2 , moving connection holes 312 are respectively provided in the middle and both end regions of the stamping plate 31. One end of the first telescopic rod 313 is connected to the control mechanism 2, and the other end is connected to the moving connection holes 312 at both ends and passes through the moving connection holes 312 to be connected to a bracket 314 provided on the machine body 1. One end of the second telescopic rod 315 is connected to the control mechanism 2, and the other end is connected to the moving connection hole 312 in the middle, so that the control mechanism 2 controls the synchronous telescoping of the first telescopic rod 313 and the second telescopic rod 315 to drive the stamping plate 31 to move vertically and ensure the smooth movement of the stamping plate 31, so that the stamping plate 31 drives the punch 33 to move into the inner hole of the printed matter on the fixing mechanism 4 for waste cleaning of the inner hole.

[0044] In order to clean the debris remaining in the inner hole during the waste removal process, a blow pipe 321 is provided in the air blowing and fixing device 32. One end of the blow pipe 321 is connected to the control mechanism 2, and the other end passes through the air blowing and fixing device 32 and abuts against the punch 33. The control mechanism 2 can convey gas to the blow pipe 321, so that during the process of the punch 33 penetrating into the inner hole of the printed matter, the blow pipe 321 blows air into the inner hole to blow out the debris from the inner hole, reducing the chance of the debris redepositing in the inner hole, thereby keeping the inner hole clean. Especially for inner holes with irregular shapes or different sizes, the blow pipe 321 can blow air into the inner hole more flexibly to clean each part of the inner hole and reduce the residue of the debris.

[0045] Furthermore, the printed matter is placed on the fixing mechanism 4 so that the printed matter can cooperate with the punch 33 on the stamping mechanism 3 on the fixing mechanism 4 to align the inner hole of the punch 33 and the printed matter.

[0046] Specifically, referring to Figure 4 , the fixing mechanism 4 is arranged below the stamping mechanism 3 and mainly includes a fixing slide rail 41 and an adjusting slide rail 42 arranged on the fixing slide rail 41. The fixing slide rail 41 can cooperate with the adjusting slide rail 42 to form various shapes, so that printed matters with various structural shapes can be placed on the adjusting slide rail 42.

[0047] Among them, the fixing slide rails 41 are arranged in parallel at both ends of the fixing mechanism 4, and a slide rail 411 is provided in the middle of the fixing slide rails 41. The adjusting slide rail 42 is composed of a first-section slide rail 421 and a second-section slide rail 422 connected in cooperation. The first-section slide rail 421 and the second-section slide rail 422 can be butted into a vertical state, so that the adjusting slide rail 42 is vertically connected to the fixing slide rail 41 and can move axially along the slide rail 411. When moved to the required position, the first-section slide rail 421 and the second-section slide rail 422 are respectively connected to the slide rail 411 in the fixing slide rails 41 at both ends through bolts to fix the position of the adjusting slide rail 42.

[0048] Furthermore, when the first-section slide rail 421 and the second-section slide rail 422 of the adjusting slide rail 42 are butted, the overall length of the adjusting slide rail 42 is slightly smaller than the distance between the fixing slide rails 41 at both ends, providing space for the rotation of the first-section slide rail 421 and the second-section slide rail 422, so that the first-section slide rail 421 and the second-section slide rail 422 can be distributed at an angle and are respectively connected to the slide rail 411, so that the adjusting slide rail 42 changes from a vertical state to a bent state and can be connected to the fixing slide rail 41, so that multiple adjusting slide rails 42 present different shapes at different positions on the fixing slide rail 41, so that the fixing slide rail 41 and the adjusting slide rail 42 cooperate to form various shapes and are adapted to printed matters of various shapes.

[0049] Combined with Figures 4 to 5b, in order to enable the adjustment slide rail 42 to change from a vertical state to a bent state, the first-stage slide rail 421 and the second-stage slide rail 422 are connected in cooperation through an elastic flexible cable 423. One end of the elastic flexible cable 423 passes through the first-stage slide rail 421 and is connected to the top of the first-stage slide rail 421, and the other end passes through the second-stage slide rail 422 and is connected to the bottom of the second-stage slide rail 422. When the first-stage slide rail 421 and the second-stage slide rail 422 are arranged at an angle, the elastic flexible cable 423 is in a stretched state to generate an elastic force and bends along the distribution angle of the first-stage slide rail 421 and the second-stage slide rail 422. At this time, the first-stage slide rail 421 and the second-stage slide rail 422 are respectively connected to the fixed slide rail 41 so that the elastic flexible cable 423 can stabilize the bent state of the first-stage slide rail 421 and the second-stage slide rail 422. When the first-stage slide rail 421 and the second-stage slide rail 422 are docked from the bent state, the elastic flexible cable 423 will tighten and connect the first-stage slide rail 421 and the second-stage slide rail 422 under the action of the elastic force, ensuring that the first-stage slide rail 421 and the second-stage slide rail 422 are in a vertical state, thereby ensuring the structural stability of the adjustment slide rail 42 in various shapes.

[0050] Furthermore, a limit connecting member 4211 is provided at the end of the first-stage slide rail 421 that cooperates with the second-stage slide rail 422. When the elastic flexible cable 423 tightens and connects the first-stage slide rail 421 and the second-stage slide rail 422 under the action of the elastic force, the limit connecting member 4211 can be placed in the second-stage slide rail 422 and abuts against the end of the second-stage slide rail 422, preventing the first-stage slide rail 421 and the second-stage slide rail 422 from colliding under the action of the elastic force and ensuring that the first-stage slide rail 421 and the second-stage slide rail 422 do not shift during the docking process.

[0051] Thus, the adjustment slide rail 42 can move on the fixed slide rail 41, can be in a vertical state, and can also change to a bent state. Multiple adjustment slide rails 42 at different positions and shapes cooperate to adapt to printed materials of various structural shapes. The pressing device 43 on the adjustment slide rail 42 cooperates with the adjustment slide rail 42 to fix the peripheral surface, top surface, and bottom surface of the printed material, so that the printed material is stable on the fixing mechanism 4 and will not warp and deform under the pressure generated when the punch 33 penetrates the inner hole.

[0052] Furthermore, referring to Figure 6 , the adjustment slide rail 42 is configured with a U-shaped cross-section, a chute 425 is formed in the middle to accommodate the sliding connecting member 424, and a limit plate 426 is provided at the top of the chute 425 so that the sliding connecting member 424 can move in the chute 425 and be connected to the pressing device 43 at any position on the adjustment slide rail 42. At the same time, the limit plate 426 limits the sliding connecting member 424 to prevent the sliding connecting member 424 from falling off from the top of the chute 425.

[0053] In cooperation with it, referring to Figure 7 andFigure 8 The pressing device 43 is formed by vertically connecting a first pressing plate 431 and a second pressing plate 432. The first pressing plate 431 is arranged in an L shape on the adjusting slide rail 42 and is connected to the sliding connecting member 424 in the sliding groove 425, so that the first pressing plate 431 abuts against the peripheral surface of the printed matter, and the second pressing plate 432 abuts against the top surface of the printed matter.

[0054] Furthermore, a connecting rod 4321 is provided at the bottom of the second pressing plate 432, and a connecting groove 4311 adapted to the connecting rod 4321 is provided at the top of the first pressing plate 431, so that the second pressing plate 432 can insert the connecting rod 4321 into the connecting groove 4311 of the first pressing plate 431. At the same time, an elastic member 4322 is sleeved on the connecting rod 4321. The elastic member 4322 is composed of a spring, one end is connected to the bottom of the second pressing plate 432, and the other end is connected to the top of the first pressing plate 431, so that the connecting rod 4321 of the second pressing plate 432 moves vertically in the connecting groove 4311. When driving the second pressing plate 432 to move and increase the distance between the second pressing plate 432 and the first pressing plate 431, the elastic member 4322 is in a stretched state to generate an elastic force, and drives the second pressing plate 432 to move under the action of the elastic force to reduce the distance between the second pressing plate 432 and the first pressing plate 431, so that the second pressing plate 432 presses the top surface of the printed matter under the action of the elastic force.

[0055] At the same time, by pulling the second pressing plate 432 to move and increase the distance between the second pressing plate 432 and the first pressing plate 431, the pressing device 43 can be adapted to printed matters of different thicknesses. The second pressing plate 432 can press the top surface of the printed matter under the action of the elastic force, preventing the printed matter from warping and deforming under the pressure of the punch 33 penetrating into the inner hole.

[0056] In order to collect and process the waste paper and debris generated when the punch 33 penetrates into the inner hole of the printed matter for waste removal, a collecting mechanism 5 is further provided on the machine body 1. The collecting mechanism 5 is detachably connected to the machine body 1 and is placed at the bottom of the fixing mechanism 4 to collect the waste paper and debris falling from the inner hole of the printed matter on the fixing mechanism 4, and the collecting mechanism 5 is detached from the machine body 1 for cleaning.

[0057] The control mechanism 2 is configured to be able to convey gas to the air blowing pipe 321, so that the air blowing pipe 321 blows air into the inner hole to clean the debris. The control mechanism 2 further includes a manual adjustment device 21 and an automatic working device 22 to control the slow movement of the stamping mechanism 3 through the manual adjustment device 21 and adjust the punch 33 to correspond to the inner hole of the printed matter. After the punch 33 corresponds to the inner hole, the stamping mechanism 3 is controlled to move quickly through the automatic working device 22, so that the punch 33 can quickly penetrate into the inner hole for waste removal, accelerating the working speed.

[0058] Here, the manual adjustment device 21 is composed of control buttons provided on the control mechanism 2, and the automatic working device 22 is composed of a foot pedal connected to the control mechanism 2. The automatic working device 22 is movable so that the automatic working device 22 can be placed at a position convenient for the worker to operate.

[0059] Furthermore, safety devices 44 are also provided on both sides of the fixing mechanism 4. The safety device 44 is preferably composed of an infrared safety induction device, so that the safety device 44 can detect the presence of safety hazard objects in the fixing mechanism 4. For example, when detecting the hand of an operating worker, the safety device 44 sends a stop signal to the control mechanism 2, so that the control mechanism 2 controls the stamping mechanism 3 to stop working to ensure the safety of the worker.

[0060] The following is an example to illustrate the working process of the present utility model in specific applications. It should be noted here that the described content is only a specific application example of this solution and does not limit this solution.

[0061] First, multiple adjustment tracks 42 move on the fixed track 41. By docking the first section of the slide rail 421 and the second section of the slide rail 422 to be in a vertical state or in an angular distribution to be in a bent state, the multiple adjustment slide rails 42 at different positions and shapes cooperate to adapt to the structural shape of the printed matter.

[0062] Place the pressing device 3 on the adjustment slide rail 42. The first pressing plate 431 is connected to the sliding connector 424 in the sliding groove 425, and the second pressing plates 432 of multiple pressing devices 3 are stretched in sequence to place the printed matter on the adjustment track 42, and make the first pressing plate 431 abut against the peripheral surface of the printed matter, and the second pressing plate 432 presses the top surface of the printed matter under the action of elastic force.

[0063] Next, connect the punch 33 adapted to the inner hole of the printed matter to the air blowing fixing device 32, and connect the air blowing fixing device 32 to the mounting hole 311 corresponding to the inner hole of the printed matter on the stamping plate 31, so that the punch 33 corresponds to the inner hole of the printed matter.

[0064] Control the stamping mechanism 3 to move slowly through the manual adjustment device 21 of the control mechanism 2 to appropriately adjust the position of the air blowing fixing device 32 so that the punch 33 corresponds to the inner hole of the printed matter.

[0065] Next, control the stamping mechanism 3 to move quickly through the automatic working device 22 of the control mechanism 2 so that the punch 33 can quickly penetrate into the inner hole for waste cleaning.

[0066] At the same time, the control mechanism 2 conveys gas to the air blowing pipe 321 so that the air blowing pipe 321 blows air into the inner hole to clean the debris in the inner hole.

[0067] The waste removing machine for inner holes provided by the utility model is adapted to printed matters with various structural shapes through the cooperation of the adjusting track 42 and the pressing device 43 in the fixing mechanism 4, and fixes the peripheral surface, top surface and bottom surface of the printed matter, so that the printed matter is not easily warped and deformed under the pressure of the punch 33; meanwhile, the inner hole is blown by the air blowing fixing device 32 in the stamping mechanism 3 to clean the debris in the inner hole and reduce the debris residue.
