Description

Technical Field

[0001] The utility model belongs to the technical field of material slitting, and particularly relates to a narrow material slitting machine. Background Art

[0002] With the continuous update and development of the electronic product industry, the requirements for the auxiliary electronic product die-cutting industry are getting higher and higher. For example, some products such as insulation, filling, and PC materials are required to be thick, thin, long, with back glue added, and the product quality needs to be ensured. Then, the requirements for its warpage, straightness, inclination, profile, tolerance accuracy, etc. are correspondingly higher to meet the requirements.

[0003] However, for narrow materials, it is quite difficult for the die-cutting processing industry to control its warpage, straightness, inclination, profile, tolerance accuracy, etc. to meet the requirements.

[0004] In view of the fact that PC materials are thick and hard, the existing die-cutting equipment uses a single-axis cutter, that is, the PC materials with different thicknesses are all cut in a single pass. For relatively thick PC materials, the cutter is worn during a single cut, and the die-cut products will deform, resulting in the failure to meet the quality requirements and the need for secondary punching, with low efficiency. Content of the Utility Model

[0055] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, 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. The described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0056] Therefore, the following detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0057] The embodiment of the present utility model provides a narrow material slitting machine to solve the problems of low precision and poor quality of the products after slitting when the existing die-cutting equipment is used for slitting PC materials.

[0058] As Figure 1 shown, the narrow material slitting machine provided in this embodiment includes: a frame 10 and a cutter roller mechanism and a pressure roller mechanism installed on the frame 10. The cutter roller mechanism and the pressure roller mechanism are vertically distributed and drivingly connected; the cutter roller mechanism includes a plurality of cutter roller assemblies 20, and the plurality of cutter roller assemblies 20 are arranged in parallel along the conveying direction of the material, and each cutter roller assembly 20 is movably arranged longitudinally through a first adjusting assembly 21 to adjust its slitting depth, and the slitting depths of the plurality of cutter roller assemblies 20 gradually increase along the conveying direction of the material; the pressure roller mechanism includes a plurality of pressure roller assemblies 30, and the plurality of pressure roller assemblies 30 are arranged in parallel along the conveying direction of the material; each cutter roller assembly 20 is opposite to and drivingly connected with a pressure roller assembly 30.

[0059] In this embodiment, the number of the cutter roller assemblies 20 is the same as that of the pressure roller assemblies 30, and each cutter roller assembly 20 is disposed opposite to and in driving connection with a pressure roller assembly 30 up and down.

[0060] In addition, a plurality of cutter roller assemblies 20 are arranged in parallel and at equal intervals along the conveying direction of the material. Similarly, a plurality of pressure roller assemblies 30 are arranged in parallel and at equal intervals along the conveying direction of the material.

[0061] Since the first adjusting assembly 21 is used to adjust the cutting depth of the cutter roller assembly 20, it can also be understood that the first adjusting assembly 21 is used to adjust the distance between the cutter roller assembly 20 and the corresponding pressure roller assembly 30.

[0062] Then, at least two first adjusting assemblies 21 are provided, and the two first adjusting assemblies 21 are respectively connected to both ends of the cutter roller assembly 20 to synchronously adjust the cutting depth of the cutter roller assembly 20. That is, the distance between the cutter roller assembly 20 and the pressure roller assembly 30 is synchronously adjusted. Thereby, the narrow material slitting machine can realize slitting of materials with different thicknesses, and has a wide range of applications.

[0063] In addition, in this embodiment, it should be clear that along the conveying direction of the material, the cutting depths of a plurality of cutter roller assemblies 20 are deepened at equal intervals, and the cutting depth of the last cutter roller assembly 20 is the thickness of the material. The difference in the cutting depths set between two adjacent cutter roller assemblies 20 is set according to the number of cutter roller assemblies 20.

[0064] In this embodiment, the number of the cutter roller assemblies 20 is at least two. Similarly, the number of the pressure roller assemblies 30 is the same as that of the cutter roller assemblies 20. The specific distance between two adjacent cutter roller assemblies 20 is not limited.

[0065] In some alternative embodiments, the number of the cutter roller assemblies 20 can also be set according to the length of the material.

[0066] In this embodiment, with respect to the thickness of the material to be slit and in combination with the setting of the number of the cutter roller assemblies 20, an example of setting the cutting depth of each cutter roller assembly 20 is given.

[0067] Assume that the thickness of the material to be slit is 1.0 MM, and the number of the cutter roller assemblies 20 is set to 5. Then, along the conveying direction of the material, the cutting depths of the cutter roller assemblies 20 are sequentially set to 0.2 MM, 0.4 MM, 0.6 MM, 0.8 MM, and 1.0 MM. In cooperation with the pressure roller assembly 30, the slitting of the material is completed in one-time segmentation, ensuring the slitting accuracy and slitting quality of the material.

[0068] As a preferred embodiment, this embodiment optimizes the installation structure of the cutter roller mechanism and the pressure roller mechanism.

[0069] Such asFigure 2 As shown in the figure, the frame 10 at least includes two side plates that are opposite and parallel to each other. The knife roller mechanism and the pressure roller mechanism are installed between the two side plates, and the knife roller mechanism and the pressure roller mechanism are distributed vertically.

[0070] Both ends of the pressure roller assembly 30 are respectively rotatably connected to the two side plates through the fifth bearing members 301. Adjacent pressure roller assemblies 30 are connected by a transition plate 60, and the upper surface of the pressure roller assembly 30 and the transition plate 60 are in the same plane, so as to realize the conveyance and rolling pressure of the material and ensure the rolling quality of the material.

[0071] A plurality of card slots 11 are provided at the upper ends of the two side plates. Both ends of the knife roller assembly 20 are embedded in the card slots 11 and are respectively rotatably connected to the two side plates.

[0072] In this embodiment, the number of the card slots 11 on the side plates is the same as the number of the knife roller assemblies 20. The plurality of card slots 11 are arranged at equal intervals along the conveying direction of the material, so as to limit the knife roller assemblies 20 and ensure that the distance between adjacent knife roller assemblies 20 is the same.

[0073] As a preferred embodiment, the specific structure of the knife roller assembly 20 is optimized in this embodiment.

[0074] As Figures 3 - 8 shown in the figure, the knife roller assembly 20 includes: a knife roller shaft 201, a cutting knife 202 and a limiting member 203 sleeved on the knife roller shaft 201. A limiting groove is provided on the outer wall of the knife roller shaft 201, and the limiting member 203 is sleeved and installed in the limiting groove and is located on both sides of the cutting knife 202 to limit the position of the cutting knife 202; a second adjusting assembly 22 is provided at the first end of the knife roller shaft 201, and the knife roller shaft 201 moves horizontally through the second adjusting assembly 22 to adjust the cutting position of the cutting knife 202.

[0075] Specifically, limiting grooves can be provided on both opposite sides of the cutting knife 202. The diameter of the limiting grooves is the same as the diameter of the limiting member 203, so that the limiting member 203 can limit and fix the cutting knife 202; in addition, after the limiting member 203 is installed in the limiting groove, it can also be locked by a nut.

[0076] In this embodiment, it should be clear that the cutting depth of the knife roller assembly 20 refers to the cutting depth of the cutting knife 202, and can also be understood as the distance between the cutting knife 202 and the pressure roller assembly 30.

[0077] Based on the fact that the thickness of the material remains consistent during the cutting process, then, along the conveying direction of the material, the cutting depth of the cutting knife 202 of the knife roller assembly 20 gradually increases, and at the same time, the distance between the limiting member 203 and the pressure roller assembly 30 always remains consistent.

[0078] In some alternative embodiments, to achieve the above design, the structures of several pressing roller assemblies 30 are the same. Assuming that the radial lines of the cutter roller shafts 201 of several cutter roller assemblies 20 are located in the same plane, then, the diameter of the cutting knives 202 needs to be gradually increased.

[0079] Assume that the diameter of the cutting knives 202 remains unchanged. Then, the height of the pressing roller assemblies 30 needs to be adjusted. At the same time, the diameter of the limiting members 203 is gradually decreased. At this time, the radial lines of the cutter roller shafts 201 of several cutter roller assemblies 20 gradually approach the radial lines of the pressing roller assemblies 30.

[0080] In some alternative embodiments, the number of cutting knives 202 is not limited to one, and can also be multiple, which is specifically determined according to the number of strips into which the material needs to be cut. The spacing between two adjacent cutting knives 202 is determined according to the size of the material to be cut, and is limited and fixed by the limiting members 203.

[0081] In this embodiment, the second adjusting assembly 22 includes a first mounting seat 221 and a first knob member 222. The opposite end of the first knob member 222 is inserted into the first mounting seat 221 from the first end of the first mounting seat 221 and is rotatably connected to the first end of the second mounting seat 221. The first end of the cutter roller shaft 201 extends from the second end of the first mounting seat 221 into the first mounting seat 221 and is rotatably connected to the first mounting seat 221, and the cutter roller shaft 201 moves horizontally during the rotation of the first knob member 222.

[0082] Specifically, the first end of the cutter roller shaft 201 extends from the second end of the first mounting seat 221 into the second mounting seat 221 and is rotatably connected to the first end of the first mounting seat 221 through a first bearing member 223. The opposite end of the first knob member 222 is inserted into the first mounting seat 221 from the first end of the first mounting seat 221 and is rotatably connected to the first end of the second mounting seat 221, and the cutter roller shaft 201 moves horizontally during the rotation of the first knob member 222, so as to adjust the horizontal position of the cutting knives 202, so that the cutting knives 202 of multiple cutter roller assemblies 20 are located on the same straight line.

[0083] In addition, as a preferred embodiment, the second adjusting assembly 22 further includes a first pressing member 224. The first pressing member 224 is movably installed in the first mounting seat 221, and the opposite ends of the first pressing member 224 are respectively abutted against the first knob member 222 and the first end of the cutter roller shaft 201. The first knob member 222 forces the first pressing member 224 to squeeze the cutter roller shaft 201 to move horizontally during the rotation process.

[0084] Specifically, the first pressing member 224 can be movably installed in the first mounting seat 221 through the second bearing member 225. The opposite side of the first pressing member 224 to the first knob member 222 abuts against the first knob member 222, and the opposite end of the first pressing member 224 to the first end of the cutter roller shaft 201 is nested, so as to ensure the stability of the cutter roller shaft 201 moving in the horizontal direction.

[0085] In addition, in order to limit the moving position of the cutter roller shaft 201 in the horizontal direction, a first limiting component 23 is provided at the second end of the cutter roller shaft 201. The first limiting component 23 includes a second mounting seat 231 and a first elastic member 232. The second end of the cutter roller shaft 201 is embedded in the second mounting seat 231 and rotatably connected to the second mounting seat 231, and the second end of the cutter roller shaft 201 is elastically connected to the bottom of the second mounting seat 231 through the first elastic member 232.

[0086] Specifically, the second end of the cutter roller shaft 201 is embedded in the second mounting seat 231 and rotatably connected to the second mounting seat 231 through a third bearing member 233.

[0087] Preferably, the first limiting component 23 further includes a second pressing member 234. The second pressing member 234 is movably installed in the second mounting seat 231, and the opposite ends of the second pressing member 234 respectively abut against the first elastic member 232 and the second end of the cutter roller shaft 201.

[0088] Specifically, the second pressing member 234 can be movably installed in the second mounting seat 231 through a fourth bearing member 235. The opposite side of the second pressing member 234 to the first elastic member 232 abuts against the first elastic member 232, and the opposite end of the second pressing member 234 to the second end of the cutter roller shaft 201 is nested, so as to ensure the stability of the cutter roller shaft 201 moving in the horizontal direction.

[0089] As a preferred embodiment, the specific structure of the first adjusting component 21 is optimized in this embodiment.

[0090] The first adjusting component 21 includes a second knob member 211 and a second elastic member 12. The second elastic member 12 is installed on the frame 10 through a third mounting seat 13. The cutter roller assembly 20 is located between the second knob member 211 and the second elastic member 12, and is elastically connected to the second elastic member 12 during the rotation of the second knob member 211.

[0091] Specifically, the second elastic member 12 is installed in the card slot 11 of the frame 10 through a third mounting seat 13. The second knob member 211 is fixedly installed on the side plate of the frame 10 through a fourth mounting seat 212, and the opposite end of the second knob member 211 to the cutter roller assembly 20 extends out of the fourth mounting seat 212 and abuts against the cutter roller assembly 20, so as to adjust the slitting depth of the cutter roller assembly 20.

[0092] In this embodiment as a preferred embodiment, the first elastic member 232 and the second elastic member 12 are springs.

[0093] In addition, in this embodiment, the transmission connection structure of the cutter roller assembly 20 and the pressure roller assembly 30 is also optimized.

[0096] Specifically, the driving gear 402, the plurality of driven gears 403, the first gear member 31, and the second gear member 24 are all installed on the same side plate of the frame 10. In view of the fact that the plurality of first gear members 31 are arranged in parallel and at equal intervals, then, the driving gear 402 and the plurality of driven gears 403 are also arranged in parallel and at equal intervals, and two adjacent first gear members 31 are respectively meshed with a driven gear 403 or the driving gear 402, so as to gradually drive the first gear member 31 and the driven gears 403 to rotate synchronously during the rotation of the driving gear 402.

[0097] In some alternative embodiments, the narrow material slitting machine further includes a discharging mechanism 50.

[0098] As Figure 10 shown, the discharging mechanism 50 is installed on the frame 10 and located at the output end of the cutter roller mechanism and / or the pressure roller mechanism; the discharging mechanism 50 includes a discharging plate 51 and a plurality of second limiting components 53.
