Description

Technical Field

[0001] The utility model relates to the technical field of paper material slitting, indentation and feeding, in particular to a thin blade slitting and indentation machine. Background Technique

[0002] A thin blade paper slitting and indentation machine is a device used for cutting and indenting paper. It is usually used in the printing, packaging and paper product processing industries to create folding lines or folding marks on paper for subsequent folding, binding or packaging during the processing. The main working principle of the thin blade paper slitting and indentation machine is to achieve the cutting and indentation of paper through a set of cutting tool systems. It is a common device in the cardboard processing industry. Through two pressure wheels, indentations are left on the cardboard, and it is very convenient for the cardboard to be bent along the indentations. At the same time, the redundant components on both sides of the cardboard are also cut off by the cutting tools.

[0003] After retrieval, a Chinese patent with the authorization announcement number CN213533978U relates to a thin blade slitting and indentation machine, which includes a machine body. A slitting and indentation mechanism and a feeding table are arranged on the machine body. A feeding positioning device is arranged on the feeding table. The feeding positioning device includes a fixing plate arranged on the feeding table. The fixing plate is arranged vertically, and the plane where the fixing plate is located is parallel to the conveying direction of the slitting and indentation mechanism. This application has the effect of keeping the relative positions of different cardboard sheets entering the slitting and indentation mechanism consistent and improving the uniformity of the quality of the same batch of cardboard box products.

[0004] Combined with the common knowledge in actual application, the above patent has the following defects: 1. A movable plate is provided, and the distance formed between the movable plate and the fixing plate can limit and guide the paper material. However, it is necessary for the operator to place the paper material in advance according to the range of this distance, which increases the difficulty of the operator's feeding and reduces the feeding efficiency; 2. The paper material positioned on the feeding table is fed by a driving roller. Since there is no corresponding limiting device at the top of the paper material, the driving roller is prone to slipping when driving the paper material to feed, resulting in the problem of ineffective feeding, which causes the paper material to pause on the feeding table and affects the indentation efficiency. In view of this, we propose a thin blade slitting and indentation machine. Content of the Utility Model

[0005] The purpose of the embodiment of the utility model is to provide a thin blade slitting and indentation machine, which solves the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A thin knife slitting and indentation machine includes a machine body and a loading table installed on the machine body.

A roller is movably connected inside the limit frame. A pneumatic box is connected to the roller. A pneumatic plate is slidably connected inside the pneumatic box. A connecting rod is fixedly connected to the pneumatic plate. A spring is connected between the surface of the connecting rod and the surface of the pneumatic box. The pneumatic box is fixed to the positioning plate through a communicating pipe. The electric push rod is installed on the bottom of the loading table, and an extrusion plate is connected to the output shaft of the electric push rod.

[0012] Preferably, the pneumatic passive device further includes a pneumatic strip. A plug plate is piston-connected inside the pneumatic strip. A rack is fixedly connected to the plug plate. A gear is engaged with the surface of the rack.

[0014] By means of the above technical solution, the present utility model provides a thin knife slitting and indentation machine, which at least has the following beneficial effects:

[0015] (1) The thin-blade slitting and indentation machine can drive two positioning plates to move automatically closer through the setting of a driving device, achieving the effect of automatically aligning the paper material. The moving distance of the positioning plate can be adjusted, further achieving the purpose of the positioning plate adapting to align according to the size of the paper material. While guiding and limiting the paper material, it avoids the problem of the operator's feeding limitation, thereby improving the practicability and applicability of the positioning plate on the feeding table. Combining with the pneumatic passive device to drive the spring telescopic rod on the rotating shaft, and using the limiting movement of the sliding shaft in the track guiding chute, it controls the top of the feeding roller to translate and feed the paper material, and uses the thrust at the top to drive the paper material to move and feed, which can avoid the problem of slipping and improve the effective feeding of the paper material.

[0016] (2) The thin-blade slitting and indentation machine can feed paper materials of different sizes through the setting of the pneumatic passive device and the feeding roller moving along with the positioning plate, greatly improving the applicability of this solution. The solution of using the rotation of the power arm to drive the positioning plate to achieve limiting and guiding can reduce the occupied area of the device. Using the magnetic positioning method to limit the positioning plate, instead of the traditional chute and slider design, while achieving stable limiting, it avoids the problem that the design of the chute causes impurities to get stuck in the chute and affect the movement of the positioning plate.

Detailed implementation manners

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , a technical solution provided by the present utility model:

[0025] A thin knife slitting and indentation machine includes a machine body 1 and a loading table 2 installed on the machine body 1. A driving device 3 is arranged on the loading table 2, and two symmetrically arranged positioning plates 4 are provided on the left and right. Two magnetic blocks 11 are fixedly connected to the bottom of the positioning plate 4. A magnetic strip 12 corresponding to the magnetic blocks 11 in both quantity and position is fixedly connected to the loading table 2. The magnetic blocks 11 are magnetically connected to the magnetic strip 12. The positioning plate 4 is limited by means of magnetic positioning, replacing the traditional design of sliding grooves and sliders. While achieving stable limitation, the problem that impurities are stuck in the sliding grooves and affect the movement of the positioning plate 4 due to the design of the sliding grooves is avoided. An air pressure passive device 5 is arranged on the loading table 2. A rotating shaft 6 is rotatably connected to the positioning plate 4. A torsion spring is sleeved on the rotating shaft surface of the rotating shaft 6 located inside the positioning plate 4. Two ends of the torsion spring are respectively connected to the rotating shaft 6 and the positioning plate 4. A loading roller 8 is connected to the rotating shaft 6 through a spring telescopic rod 7. The spring telescopic rod 7 is a prior art and is composed of two or more telescopic and movable sleeve rods. Springs are arranged inside the sleeve rods for elastic limitation. A sliding shaft 9 is connected to the spring telescopic rod 7. A trajectory guiding sliding groove 10 is formed on the positioning plate 4 for limiting the trajectory of the sliding shaft 9 during rotation. The trajectory guiding sliding groove 10 is composed of an arc groove and a flat groove. The arc groove is the same as the rotation trajectory of the sliding shaft 9 itself. When the sliding shaft 9 slides in the arc groove and then passes through the flat groove, it will be restricted by the flat groove, and the sliding shaft 9 can only move linearly in the flat groove.

[0026] In this embodiment, the driving device 3 includes a driving motor 31. The surface of the driving motor 31 is detachably mounted on one side of the loading table 2 through bolts. A connecting worm 32 is clamped on the output shaft of the driving motor 31. The connecting worm 32 is composed of a rod and two worms. Its end is rotatably connected to the bottom of the loading table 2. Two connecting worm wheels 33 are meshed with the surface of the connecting worm 32 through the two worms. The end face of the connecting worm wheel 33 is rotatably connected inside the loading table 2. A power arm 34 is connected to the connecting worm wheel 33. The end of the power arm 34 is rotatably connected to a connecting seat 35. The surface of the connecting seat 35 is slidably connected to the surface of the positioning plate 4. The solution of driving the positioning plate 4 to achieve limit guiding by rotating the power arm 34 can achieve the effect of reducing the occupied area of the device. The driving motor 31 drives the connecting worm 32 to mesh with the two connecting worm wheels 33. The connecting worm wheels 33 drive the connecting seat 35 to drive the positioning plate 4 to move through the power arm 34, driving the two positioning plates 4 to move closer. The two positioning plates 4 can achieve the effect of automatically aligning the paper material during the approaching process. By controlling the number of turns of the output shaft of the driving motor 31, the effect of regulating the moving distance of the positioning plate 4 can be achieved, further achieving the purpose of the positioning plate 4 being adaptively aligned according to the paper material size. While guiding and limiting the paper material, the problem of the operator's feeding limitation is avoided, thereby improving the practicability and applicability of the positioning plate 4 on the loading table 2.

[0027] Furthermore, the pneumatic passive device 5 includes an electric push rod 51, a limit frame 52, and a pneumatic strip 58. The top of the limit frame 52 is fixedly connected to the bottom of the loading table 2. A roller 53 is rotatably connected inside the limit frame 52. A pneumatic box 54 is movably connected to the roller 53. A pneumatic plate 55 is slidably connected inside the pneumatic box 54. A connecting rod 56 is fixedly connected to the surface of the pneumatic plate 55. A spring is connected between the end surface of the connecting rod 56 and the surface of the pneumatic box 54. One side of the pneumatic box 54 is fixedly connected to a communicating pipe 57. The end of the communicating pipe 57 is fixedly connected to one side of the positioning plate 4. The electric push rod 51 is detachably installed at the bottom of the loading table 2 through bolts, and an extrusion plate 512 is clamped on the output shaft of the electric push rod 51. The surface of the pneumatic strip 58 is fixed on the outer side surface of the positioning plate 4. A piston in the pneumatic strip 58 is connected to a plug plate 59. A rack 510 is fixedly connected to the outer side surface of the plug plate 59. A gear 511 is engaged with the surface of the rack 510. The inside of the gear 511 is fixed on the end surface of a rotating shaft 6. The pneumatic strip 58 is communicated with the communicating pipe 57 through a communicating cavity in the positioning plate 4. By providing the pneumatic passive device 5, using the property that the pneumatic passive device 5 can move correspondingly with the positioning plate 4 on the positioning plate 4, it can drive the feeding of paper materials of different sizes, greatly improving the applicability of this solution. Using the air pressure generated by the driving structure of the electric push rod 51, the rotation of the rotating shaft 6 is controlled in a linked manner. The rotating shaft 6 controls the top of the paper material to be fed horizontally through the limiting movement of the upper sliding shaft 9 of the spring telescopic rod 7 in the track guiding chute 10, and drives the paper material to move and feed using the thrust at the top, which can avoid the problem of slipping and improve the effective feeding of the paper material.

[0028] When a thin blade slitting and indentation machine of the present utility model is in use, the two positioning plates 4 on the loading table 2 are always in a state of the maximum spacing value under normal conditions. During the paper material loading process on the loading table 2 by the operator, the restrictions on the placement of the paper material are reduced, which can improve the loading rate of the paper material by the operator. During the loading process, the positioning plates 4 move regularly according to the program setting. By starting the driving motor 31, the output shaft of the driving motor 31 meshes with two symmetrically arranged connecting worm wheels 33 through two laterally symmetrically arranged worms on the connecting worm 32. The connecting worm wheel 33 drives the connecting seat 35 to move through the power arm 34. Since the two symmetrically arranged magnetic blocks 11 at the bottom of the connecting seat 35 are magnetically limited by the two magnetic strips 12, the connecting seat 35 can only move along the shape trajectory of the magnetic strip 12, that is, the connecting seat 35 can only perform a horizontal linear motion. Then, during the rotation of the power arm 34, the positioning plate 4 will be driven to move through the connecting seat 35. The connecting seat 35 performs a linear limited motion on the positioning plate 4, so as to achieve the effect of driving the two positioning plates 4 to approach each other. During the approaching process of the two positioning plates 4, the effect of automatically aligning the paper material can be achieved. By controlling the number of turns of the output shaft of the driving motor 31, the effect of regulating the moving distance of the positioning plate 4 can be achieved, and further the purpose of the positioning plate 4 being adaptively aligned according to the paper material size can be achieved. While guiding and limiting the paper material, the problem of the operator's loading restrictions is avoided, and then the practicability and applicability of the positioning plate 4 on the loading table 2 are improved.

[0029] Meanwhile, during the movement of the positioning plate 4, it can synchronously drive the entire pneumatic box 54 to move through the connecting pipe 57. When the positioning plate 4 completes the positioning of the paper material, it temporarily stops in the positioning area. At this time, the electric push rod 51 drives the extrusion plate 512 to move through the output shaft. During the movement of the extrusion plate 512, it extrudes the connecting rod 56. After being pressed, the connecting rod 56 retracts against the spring force. During the retraction of the connecting rod 56, it extrudes the gas in the pneumatic box 54 through the pneumatic plate 55. The compressed gas flows from the positioning plate 4 into the air pressure strip 58 through the connecting pipe 57. The air pressure drives the plug plate 59 in the air pressure strip 58 to move outward. The plug plate 59 drives the gear 511 to rotate through the rack 510. The gear 511 drives the entire spring telescopic rod 7 to rotate through the rotating shaft 6. During the rotation of the spring telescopic rod 7, its upper sliding shaft 9 will gradually move into the track guiding chute 10. The track guiding chute 10 is composed of an arc chute and a flat chute. The arc chute is the same as the rotation trajectory of the sliding shaft 9 itself. When the sliding shaft 9 slides in the arc chute and then passes through the flat chute, it will be limited by the flat chute. The sliding shaft 9 can only move linearly in the flat chute. At this time, the sliding shaft 9 is subjected to the limiting force of the chute, driving the spring telescopic rod 7 to contract. The sliding shaft 9 sliding in the flat chute will drive the feeding roller 8 to push from the top of the paper material through the spring telescopic rod 7. The thrust drives the paper material to move for feeding. After feeding, the paper material is automatically fed by being squeezed by the transmission roller on the machine body 1 itself, thus realizing the automatic pushing of the material plate, facilitating the automatic entry of the paper material into the slitting and indentation area for work. At the same time, by using the method of top extrusion to feed the material plate on the feeding table 2, the problem of slipping can be avoided, and the effective feeding of the paper material can be improved.

[0030] Meanwhile, the present solution adopts the setting that the pneumatic passive device 5 and the feeding roller 8 move along with the positioning plate 4, enabling it to feed paper materials of different sizes, greatly improving the applicability of the present solution; and the solution that drives the positioning plate 4 to achieve limit guiding by rotating the power arm 34 can achieve the effect of reducing the occupied area of the device; the method of magnetic positioning is used to limit the positioning plate 4, replacing the traditional design of the chute and slider. While achieving stable limiting, it avoids the problem that the design of the chute causes impurities to get stuck in the chute and affect the movement of the positioning plate 4.
