Description

Technical Field

[0001] The present invention belongs to the technical field of slitting machines, and particularly relates to a belt-type horizontal and vertical slitting machine. Background Art

[0002] A horizontal and vertical slitting machine is an industrial processing device mainly used for precisely slitting coils or sheet materials horizontally (perpendicular to the material movement direction) and longitudinally (along the material movement direction). Its core function is to cut wide-width materials into narrow-width products of different widths or lengths according to production requirements, and it is widely used in precision cutting in fields such as packaging materials (such as EPE pearl cotton, bubble film), polymer films, composite materials, etc. In the prior art, the structural design and working mode of traditional horizontal and vertical slitting machines have the following significant defects: Existing equipment generally uses metal guide rollers symmetrically arranged up and down at the feeding end and the discharging end to clamp the material, and realizes conveying through the linear contact friction force between the guide rollers and the material. However, since the contact between the guide rollers and the material is linear contact, the contact area is insufficient. When the material thickness or density fluctuates, the friction force distribution is uneven, resulting in fluctuations in the conveying speed and directly causing slitting size errors; at the same time, no synchronous conveying mechanism is provided below the vertical cutting circular knife, and the material is in a locally suspended state during cutting. Affected by the cutting resistance, the material is prone to lateral offset or wavy deformation, resulting in a decrease in the flatness of the cutting surface. Moreover, the feeding end guide roller continuously pushes the material, while the discharging end guide roller pulls back in the opposite direction to maintain the material tension. This bi-directional force forms a stress concentration area near the cutting point of the vertical cutting circular knife, causing local tensile deformation of the material. This phenomenon is particularly significant in elastic materials (such as EPE pearl cotton, elastic films), further amplifying the slitting size error. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) The belt-type horizontal and vertical cutting machine of the present invention forms a continuous planar conveying structure by horizontally and spacedly arranging a plurality of conveyor belt components on the installation bracket. Compared with the line contact transmission between the feeding guide roller and the material in the prior art, the surface contact transmission significantly increases the contact area between the material and the conveyor belt, effectively reducing the uneven distribution of friction force and the fluctuation of the conveying speed caused by the density or thickness difference of the material, ensuring the uniform conveying of the material, and thus improving the cutting size accuracy; at the same time, the vertical cutting circular knife is arranged between the front end and the rear end of the conveyor belt component, and the lower edge of the vertical cutting circular knife extends into the conveying gap.

[0019] (2) The belt-type horizontal and vertical cutting machine of the present invention realizes the lateral position adjustment of the conveyor belt component by slidably arranging the conveyor belt bracket on the first linear guide rail. The operator can quickly adjust the conveying gap between the conveyor belt components according to the position of the vertical cutting circular knife. During the material cutting, the lower edge of the vertical cutting circular knife is always located in the conveying gap, so that the material below the vertical cutting circular knife is in a supported state, ensuring the balanced force of the material during vertical cutting and improving the flatness of the cutting surface; at the same time, the conveyor belt bracket is pressed and fixed on the first linear guide rail through the conveyor belt pressing plate component.

Detailed implementation manners

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] The following will be combined with the attached Figure 1 to the attached Figure 9 and specific embodiments to elaborate on the present invention in detail.

[0033] The present invention provides a conveyor belt type vertical and horizontal slitter, which includes a frame 1 and a feeding mechanism 2, a vertical cutting mechanism 3, a horizontal cutting mechanism 4 and a discharging mechanism 5 arranged on the frame 1. The horizontal cutting mechanism 4 is located between the feeding mechanism 2 and the discharging mechanism 5, and the vertical cutting mechanism 3 is located above the feeding mechanism 2 and close to the horizontal cutting mechanism 4, wherein:

[0034] The feeding mechanism 2 includes a plurality of conveyor belt assemblies 21 arranged at intervals in the horizontal direction and synchronously conveying forward. A conveying gap 22 is formed between adjacent conveyor belt assemblies 21. The front end of the conveyor belt assembly 21 is located at the feeding end of the frame 1, and the rear end of the conveyor belt assembly 21 extends to the feeding end of the horizontal cutting mechanism 4;

[0035] The vertical cutting mechanism 3 includes a plurality of vertical cutting circular knives 31 arranged at intervals in the horizontal direction and synchronously rotating. The vertical cutting circular knives 31 are located between the front end and the rear end of the conveyor belt assembly 21, and the lower edge of the vertical cutting circular knives 31 extends into the conveying gap 22.

[0036] In the present invention, a feeding platform 7 is further provided at the feeding end of the frame 1, and a discharging platform 8 is provided on one side of the discharging end. The feeding platform 7, the discharging platform 8 and the upper surface of the conveyor belt assembly 21 are located on the same horizontal plane. Two long strip-shaped through grooves 71 are symmetrically provided on the feeding platform 7. The long strip-shaped through grooves 71 extend in the horizontal direction. A limiting component 72 is slidably connected in each long strip-shaped through groove 71. A feeding channel is formed between the two limiting components 72. To ensure that a vertical cutting circular knife 31 can be compatible with materials of various thicknesses and does not affect the cutting effect, the distance that the lower edge of the vertical cutting circular knife 31 is embedded downward into the conveying gap 22 relative to the upper surface of the conveyor belt assembly 21 is 1 mm - 3 mm. When performing material slitting, the operator first adjusts the gap between the two limiting components 72 according to the width of the material, and then adjusts the distance between the vertical cutting circular knives 3 and the conveying gap 22 between adjacent conveyor belt assemblies 21 according to the predetermined cutting width of the material. After ensuring that the lower edge of each vertical cutting circular knife 31 is located in the conveying gap 22 between adjacent conveyor belt assemblies 21, the vertical and horizontal slitting operation of the material can be started. The present invention forms a continuous plane conveying structure by arranging a plurality of conveyor belt assemblies 21 arranged at intervals in the horizontal direction and synchronously conveying forward. Compared with the line contact transmission between the feeding guide roller and the material in the prior art, the surface contact transmission significantly increases the contact area between the material and the conveyor belt assembly 21, effectively reduces the uneven distribution of friction force and the fluctuation of the conveying speed caused by the density or thickness difference of the material, ensures the uniform conveying of the material, and thus improves the slitting dimension accuracy; at the same time, the vertical cutting circular knives 31 are arranged between the front end and the rear end of the conveyor belt assembly 21, and the lower edge of the vertical cutting circular knives 31 extends into the conveying gap 22, so that the material can still be continuously and synchronously conveyed forward during vertical cutting, realizing the dynamic coordination of cutting and conveying, avoiding the material pulling deformation caused by the cutting resistance of the vertical cutting circular knives 31 in the traditional slitter, and reducing the cutting error of the material size.

[0037] Specifically, refer to Figures 6 - 9 , in some embodiments, a horizontally extending mounting bracket 11 is provided on the rack 1, a first linear guide rail 12 is provided on the mounting bracket 11, the feeding mechanism 2 further includes a conveyor belt pressing plate assembly 23 and a conveyor belt bracket 24, the conveyor belt brackets 24 are arranged in one-to-one correspondence with the conveyor belt assemblies 21, and a plurality of conveyor belt assemblies 21 are slidably arranged on the first linear guide rail 12 through the corresponding conveyor belt brackets 24;

[0038] The conveyor belt pressing plate assembly 23 includes a pressing plate member 230 and a pressing plate driving member 231 for driving the pressing plate member 230 to move up and down. The pressing plate member 230 presses the conveyor belt bracket 24 against the first linear guide rail 12 under the drive of the pressing plate driving member 231. In this embodiment, by slidably arranging the conveyor belt bracket 24 on the first linear guide rail 12, the adjustment of the conveying gap 22 between the conveyor belt assemblies 21 is realized. The operator can quickly adjust the conveying gap 22 between the conveyor belt assemblies 21 according to the position of the vertical cutting circular knife 31. When performing material cutting, the lower edge of the vertical cutting circular knife 31 is always located within the conveying gap 22, so that the material below the vertical cutting circular knife 31 is in a supported state, ensuring that the material is evenly stressed during vertical cutting and improving the flatness of the cutting surface; at the same time, the conveyor belt pressing plate assembly 23 presses and fixes the conveyor belt bracket 24 on the first linear guide rail 12, and through the rigid locking and fixing of the conveyor belt pressing plate assembly 23, the conveyor belt assemblies 21 are prevented from displacing due to vibration or load during the cutting process, with a simple structure and good stability.

[0039] Specifically, refer to Figures 6 - 9 , in some embodiments, the pressing plate driving member 231 includes a cylinder bracket 2310 and a plurality of second cylinders 2311 fixedly installed on the cylinder bracket 2310. The cylinder bracket 2310 is fixedly connected to the mounting bracket 11. A plurality of through holes are provided on the cylinder bracket 2310, and the piston rods of the plurality of second cylinders 2311 respectively pass through the through holes and are fixedly connected to the pressing plate member 230. The operator controls the telescopic movement of the piston rods of the second cylinders 2311, thereby controlling the pressing plate member 230 to press or release the conveyor belt bracket 24, realizing the fixation or release of the position of the conveyor belt assembly 21. Of course, in other embodiments, other lifting structures can also be selected, which are not limited here as long as they can drive the pressing plate member 230 to move downward to press the conveyor belt bracket 24 and realize the position fixation of the conveyor belt assembly 21.

[0040] Specifically, refer to Figures 6 - 9, in some embodiments, the conveyor belt assembly 21 includes a conveyor belt 210 and a conveyor belt driving assembly 211. The conveyor belt driving assembly 211 includes a first motor 2110 and a first speed reducer 2111. The output end of the first speed reducer 2111 is in transmission connection with the driving shaft 212. One end of each of the plurality of conveyor belts 210 is sleeved on the driving shaft 212, and the other end is sleeved on the driven shaft 213. By driving the driving shaft 212 to rotate through the conveyor belt driving assembly 211, the plurality of conveyor belts 210 are driven to rotate synchronously, so as to realize the stable forward conveying of materials. In the present application, in order to realize the synchronous rotation of the conveyor belt 210, the driving shaft 212 is a long shaft extending horizontally, and the conveyor belts 210 are all sleeved on the same driving shaft 212, while the driven shaft 213 is not limited. Each conveyor belt 210 can correspond to a short driven shaft 213, or a plurality of conveyor belts 210 can be sleeved on a long driven shaft 213.

[0041] Specifically, refer to FIG. Figures 6 - 9 , in some embodiments, the conveyor belt assembly 21 further includes a conveyor belt skeleton 214 inside the conveyor belt 210. The conveyor belt bracket 24 includes a first support seat 240 and a second support seat 241. The first support seat 240 is arranged at one end of the conveyor belt skeleton 214 close to the driving shaft 212, and a first slider 242 adapted to the first linear guide rail 12 is provided at the bottom end of the first support seat 240; the second support seat 241 is arranged at one end of the conveyor belt skeleton 214 close to the driven shaft 213, and a second slider 243 adapted to the first linear guide rail 12 is provided at the bottom of the second support seat 241. Through the double-point sliding design of the first support seat 240 and the second support seat 241, the levelness of the conveyor belt assembly 21 during the adjustment process is ensured, and the deviation of the conveyor belt 210 during material conveying due to inclination is avoided, which affects the cutting accuracy.

[0042] Specifically, refer to Figure 9 , in some embodiments, the pressing plate member 230 includes a horizontal pressing plate 2300 and a vertical pressing plate 2301 fixedly connected to one end of the horizontal pressing plate 2300. The horizontal pressing plate 2300 is pressed downwards by the pressing plate driving member 231 to press the first support seat 240 and the second support seat 241.

[0043] Specifically, refer to Figures 6 - 7, in some embodiments, the conveyor belt assembly 21 further includes a tensioning block 215 fixed to the side of the conveyor belt skeleton 214 and a support plate 216 sleeved on the driven shaft 213. The tensioning block 215 is close to the driven shaft 213. A bolt 217 is threadedly connected to the tensioning block 215. The screw end of the bolt 217 passes through the tensioning block 215 in a spiral manner and abuts against the support plate 216. Preferably, there are two tensioning blocks 215, which are symmetrically installed on both sides of the conveyor belt skeleton 214. In this embodiment, each conveyor belt 210 corresponds to a short driven shaft 213, and the driven shaft 213 is movably connected to the conveyor belt skeleton 214 through the support plate 216. In this embodiment, by screwing in or out the bolts 217 provided on both sides, the support plate 216 is pushed to move longitudinally (i.e., move back and forth along the conveyor belt skeleton 214), thereby realizing the longitudinal movement of the driven shaft 213, changing the distance between the driven shaft 213 and the driving shaft 212, and thus adjusting the tightness of the conveyor belt 210 to ensure that the conveyor belt 210 is always in a moderately tensioned state, avoiding slipping or overloading. Since the forces on the conveyor belt 210 are different during the continuous repeated work process, the tightness of the conveyor belt 210 is different. Therefore, in this application, the tension of each conveyor belt 210 is adjusted separately to achieve the flexibility of adjustment.

[0044] Specifically, refer to Figure 6 and Figure 8 , in some embodiments, the driving shaft 212 is a hexagonal shaft. The driving shaft 212 is in transmission connection with the conveyor belt 210 through a rolling shaft 218. A hexagonal through hole adapted to the shape of the hexagonal shaft is provided inside the rolling shaft 218. The hexagonal shaft and the inner hole of the rolling shaft 218 can be directly meshed through shape matching, without the need to adjust the circumferential angle, with accurate positioning and simple installation; at the same time, the driving shaft 212 with a hexagonal symmetric structure enables the shear stress generated by the torque to be evenly distributed on six planes, reducing local stress concentration, extending the service life of the driving shaft 212, and moreover, the hexagonal meshing structure can effectively suppress the vibration of the driving shaft 212 during high-speed operation, reducing the material cutting error caused by jitter.

[0045] Specifically, refer to Figures 1 - 4 , in some embodiments, the vertical cutting mechanism 3 further includes a vertical cutting drive assembly 32 and a vertical knife mounting shaft 33. The vertical knife mounting shaft 33 is horizontally mounted on the machine frame 1. The vertical cutting drive assembly 32 is in transmission connection with the vertical knife mounting shaft 33. A plurality of vertical cutting circular knives 31 are spaced and sleeved on the vertical knife mounting shaft 33 and are fixed in position through a detachably mounted circular knife seat 35. The vertical cutting drive assembly 32 includes a third motor and a third speed reducer. The output end of the third speed reducer is in transmission connection with the vertical knife mounting shaft 33, so as to realize the synchronous rotation cutting of the plurality of vertical cutting circular knives 31.

[0046] Specifically, refer to Figures 2 - 5, in some embodiments, the discharging mechanism 5 includes a discharging pressure roller 51 and a discharging lower roller 52 arranged vertically. Discharging pressure roller lifting assemblies 53 are provided at both ends of the discharging pressure roller 51. A laterally connected second linear guide rail 57 is provided between the discharging pressure roller lifting assemblies 53. The second linear guide rail 57 is located on one side of the feeding end of the cross-cutting mechanism 4. Third sliders 58 corresponding one-to-one to the vertical cutting circular knives 31 are slidably arranged on the second linear guide rail 57. Vertical knife limiting blocks 59 are provided on the third sliders 58. Vertical cutting circular knife limiting grooves 590 are provided on the vertical knife limiting blocks 59. The edges of the vertical cutting circular knives 31 are rotatably arranged in the vertical cutting circular knife limiting grooves 590, and the inner wall of the vertical cutting circular knife limiting groove 590 and the outer edge of the vertical cutting circular knife 31 are in clearance fit. In this embodiment, the vertical knife limiting block 59 is in the shape of a cuboid and is vertically installed on the third slider 58. The clearance between the outer edge of the vertical cutting circular knife 31 and the inner wall of the vertical cutting circular knife limiting groove 590 is 0.1 mm - 0.5 mm. By providing the vertical cutting circular knife limiting grooves 590 on the vertical knife limiting blocks 59 and making the vertical knife limiting blocks 59 slidably connected to the second linear guide rail 57 through the third sliders 58, not only can the radial runout of the vertical cutting circular knives 31 caused by high-speed rotation or cutting resistance be restricted, but also the blade wear caused by hard contact friction between the vertical cutting circular knives 31 and the vertical cutting circular knife limiting grooves 590 can be avoided.

[0047] Specifically, refer to Figure 1 、 Figures 4 - 5 , in some embodiments, the vertical cutting mechanism 3 further includes vertical knife lifting assemblies 34 arranged on both sides of the vertical knife mounting shaft 33. The vertical knife lifting assemblies 34 include first cylinders 340 fixedly connected to the machine frame 1. Positioning bearing seats 341 are provided at the telescopic ends of the first cylinders 340. Positioning bearings 342 are provided on the positioning bearing seats 341. Both ends of the vertical knife mounting shaft 33 are rotatably connected to the positioning bearings 342 respectively. When the cutting width of the material changes, it is necessary to adjust the distance between the vertical cutting circular knives 31. At this time, the vertical knife mounting shaft 33 can be lifted through the vertical knife lifting assemblies 34 so that the lower edge of the vertical cutting circular knives 31 is adjusted to the upper surface of the conveyor belt 210 for convenient adjustment. After the distance between the vertical cutting circular knives 31 and the conveying gap 22 of the conveyor belt assembly 21 are adjusted, the vertical knife mounting shaft 33 is lowered through the vertical knife lifting assemblies 34 so that the lower edge of the vertical cutting circular knives 31 is again located in the conveying gap 22, completing the adjustment of the height position of the vertical cutting circular knives 31.

[0048] Specifically, refer to Figure 2 and Figure 5, in some embodiments, the cross-cutting mechanism 4 includes a cross-knife lifting assembly 41 fixedly installed on the frame 1, and a transverse guillotine knife 42 is provided at the lifting end of the cross-knife lifting assembly 41. The cross-knife lifting assembly 41 includes a second motor 410, a second speed reducer 411 and a second driving shaft 412. The output end of the second motor 410 is drivingly connected to the second speed reducer 411. The output end of the second speed reducer 411 is sleeved with the second driving shaft 412. Both ends of the second driving shaft 412 are rotatably connected with connecting rod support arms 413. The upper ends of the two connecting rod support arms 413 are rotatably connected with limit posts 414. The limit posts 414 are fixedly connected to both ends of the transverse guillotine knife 42. The horizontal and vertical cutting machine in this embodiment further includes a length measurement system (not shown in the figure) for real-time detecting the conveying length of the material and generating a feedback signal. The control system controls the rotation of the second motor 410 through the feedback signal of the length measurement system and the fixed-length parameter information, drives the rotation of the second driving shaft 412, and further drives the rotation of the connecting rod support arms 413 at both ends. The rotation of the connecting rod support arms 413 will drive the up and down movement of the limit posts 414, so as to realize the vertical lifting of the transverse guillotine knife 42 fixedly connected to the limit posts 414, and realize the fixed-length horizontal cutting of the material. Of course, in other embodiments, other lifting structures can also be selected as long as the stable up and down movement of the transverse guillotine knife 42 can be realized. There is no limitation here, and those skilled in the art can design it according to production requirements by themselves.

The pressure roller mechanism 6 includes a pressure roller lifting assembly 61 installed on the frame 1.
