Description

Technical Field

[0001] The utility model relates to the technical field of EVA foam processing equipment, in particular to an EVA foam compound slitting machine. Background Technique

[0002] EVA foam is a new type of environmentally friendly plastic foaming material, which has good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance and other characteristics, and is non-toxic and non-absorbent, meeting environmental protection requirements.

[0003] A slitting machine is a device that cuts a wide-width coil into multiple narrow-width coils, and it has a wide range of application fields and various types. Generally speaking, its working principle is as follows: the slitting machine feeds the raw materials into the machine through an automatic feeding system. Subsequently, the cutting mechanism accurately cuts the material according to preset parameters, dividing it into strips of a specified width. Finally, the material receiving mechanism is responsible for collecting these cut strip-shaped materials for subsequent processing.

[0004] Generally, EVA foam is mainly made after processes such as mixing, heating, foaming, forming, and cooling of EVA resin and a foaming agent; generally, the formed EVA foam is a wide-width coil, and subsequent processing manufacturers need to use a slitting machine to cut it into narrow-width coils and then further perform slitting processing and other treatments after purchasing.

[0005] Based on this, Chinese Patent CN214081687U discloses a slitting machine for the production of a silent foam rubber for tires, which includes a machine body. On both sides of the front side of the machine body, limiting blocks are fixedly connected. On one side where the two limiting blocks are close to each other, a limiting wheel is arranged. On both sides of the limiting wheel, T-shaped blocks are fixedly connected. On the side of the limiting block close to the limiting wheel, a T-shaped groove for cooperating with the T-shaped block is opened. By the combined use of the machine body, limiting blocks, limiting wheels, T-shaped blocks, T-shaped grooves, fixing blocks, fixing grooves, limiting mechanisms, movable blocks, springs, limiting rods, transmission rods, adjusting mechanisms, pull rings, adjusting rods, transmission blocks, limiting grooves, adjusting holes, transmission grooves, sliders, sliding grooves, and limiting holes, this slitting machine solves the problem that when the existing slitting machine is processing, due to the lack of a function to limit the raw materials, the raw materials are prone to jitter during cutting, affecting the working efficiency of the slitting machine.

[0006] However, the above-disclosed slitting machine still has the technical problem of being unable to adapt to EVA foams of different thickness specifications. Specifically, in the technical solutions disclosed in the existing patents, the distance between the slitting knife shaft for cutting EVA foam and the workbench for limiting and carrying the EVA foam is constant and non-adjustable. Thus, when the thickness of the EVA foam that the processing manufacturer needs to cut and slit exceeds the distance between the slitting knife shaft and the workbench, the slitting knife shaft will be unable to perform slitting and cutting processing on this kind of foam. Summary of the Invention

[0028] Please refer to Figures 1 to 3 simultaneously. A kind of EVA foam composite slitting machine of the present utility model includes: a frame 1, a driving mechanism 2, a transmission structure 3, a supporting vertical frame 4, a first slitting knife shaft group 5, a second slitting knife shaft group 6, a spacing adjusting structure 7 and a slitting table frame 8; the driving mechanism 2 is disposed on one side above the frame 1, and the driving mechanism 2 is drivingly connected to the transmission structure 3; the supporting vertical frame 4 is fixedly connected to the frame 1 adjacent to the frame 1, the transmission structure 3 is disposed on one side surface of the supporting vertical frame 4, the transmission structure 3 is respectively connected to the first slitting knife shaft group 5 and the second slitting knife shaft group 6, both the first slitting knife shaft group 5 and the second slitting knife shaft group 6 are disposed in the supporting vertical frame 4, and the second slitting knife shaft group 6 is movably disposed in the supporting vertical frame 4 above the first slitting knife shaft group 5; the spacing adjusting structure 7 is respectively connected to the second slitting knife shaft group 6 and the supporting vertical frame 4, and the slitting table frame 8 is connected to the supporting vertical frame 4 between the first slitting knife shaft group 5 and the second slitting knife shaft group 6.

[0029] Specifically, when a kind of EVA foam composite slitting machine of the present utility model is in the working process, after the driving mechanism 2 is started, the first slitting knife shaft group 5 and the second slitting knife shaft group 6 are respectively driven through the transmission structure 3; so that both of them can rotate in the supporting vertical frame 4. Thereafter, the EVA foam material to be slit and cut is conveyed to the slitting table frame 8 by an external feeding mechanism and automatically fed on the slitting table frame 8 under the traction of the external conveying mechanism; so that the first slitting knife shaft group 5 and the second slitting knife shaft group 6 respectively cut the lower part and the upper part of the EVA foam material at the same time. Furthermore, the compound cutting process is realized by the two knife shaft groups to quickly slit and cut the EVA foam material. After the slitting process is completed, it flows out from the other end of the slitting table frame 8. Further, when the thickness of the conveyed EVA foam material changes, for example, the material thickness increases or decreases, at this time, the operator can turn the spacing adjusting structure 7 to drive the second slitting knife shaft group 6 to move away from or close to the first slitting knife shaft group 5, so as to adapt to different material thickness specifications of EVA foam. In addition, the spacing adjusting structure 7 can also be adjusted to realize the processing requirements of semi-cutting or full-cutting of the EVA foam material, meeting the production requirements of different processing technologies and improving the efficiency of foam cutting. Thus, it can be seen that a kind of EVA foam composite slitting machine of the present utility model solves the technical problem of how to improve the slitting and cutting efficiency of the slitting machine for EVA foam.

[0030] Further, the driving mechanism 2 has a speed reducer 201, a motor 202 and a power output gear 203; the speed reducer 201 is arranged on the frame 1, the motor 202 is drivingly connected with the speed reducer 201, and the power output gear 203 is connected with the speed reducer 201.

[0031] Further, the transmission structure 3 has a first transmission gear structure 301, a second transmission gear structure 302, a third transmission gear structure 303 and a relay gear support 304; the first transmission gear structure 301 is arranged on the side of the supporting vertical frame 4, and the power output gear 203 is meshingly connected with the first transmission gear structure 301; the two second transmission gear structures 302 are meshingly connected with each other, wherein, one second transmission gear structure 302 is meshingly connected with the first transmission gear structure 301, and the other second transmission gear structure 302 is meshingly connected with the third transmission gear structure 303; the relay gear support 304 is fixedly arranged on the frame 1 adjacent to the supporting vertical frame 4, and the two second transmission gear structures 302 are respectively movably connected to the relay gear support 304.

[0032] Further, the first slitting cutter shaft group 5 has a first bearing structure 501, a first rotating cutter shaft 502, and a plurality of first slitting cutters 503; the two first bearing structures 501 are respectively disposed oppositely on both sides of the support upright 4, the first rotating cutter shaft 502 is respectively connected to the two first bearing structures 501, the first transmission gear structure 301 is connected to the first rotating cutter shaft 502, and the plurality of first slitting cutters 503 are evenly spaced and disposed on the first rotating cutter shaft 502.

[0033] Further, the second slitting cutter shaft group 6 has a second bearing structure 601, a second rotating cutter shaft 602, and a plurality of second slitting cutters 603; the two second bearing structures 601 are respectively movably disposed oppositely on both sides of the support upright 4, and each second bearing structure 601 is correspondingly connected to a spacing adjustment structure 7; the second rotating cutter shaft 602 is respectively connected to the two second bearing structures 601, the third transmission gear structure 303 is connected to the second rotating cutter shaft 602, and the plurality of second slitting cutters 603 are evenly spaced and disposed on the second rotating cutter shaft 602.

[0034] Specifically, the spacing adjustment structure 7 can be a threaded connector. For example, it can be a connector such as a bolt with a threaded connection structure; it can pass through the top of the support upright 4 and be connected to a second bearing structure 601; thus, an operator can adjust the spacing between the second rotating cutter shaft 602 and the first rotating cutter shaft 502 by screwing the spacing adjustment structure 7, so that the second slitting cutter 603 and the first slitting cutter 503 can be adapted to EVA foam materials with different material thicknesses.

[0035] More specifically, after the motor 202 is powered on and starts, the power output by it is transmitted to the first slitting knife shaft group 5 and the second slitting knife shaft group 6 respectively through the speed regulation and torque change of the speed reducer 201 by means of the transmission structure 3. More specifically, after the power output gear 203 is driven by the speed reducer 201, it can drive the first transmission gear structure 301 through meshing transmission so that the first rotating knife shaft 502 drives each of the first slitting cutting tools 503 to perform a rotating cutting action. Further, when the power output gear 203 rotates, it also simultaneously drives a second transmission gear structure 302 to rotate. Under the action of meshing transmission, the other second transmission gear structure 302 continues to transmit the rotating power to the third transmission gear structure 303, thereby driving the second rotating knife shaft 602 so that each of the second slitting cutting tools 603 can also be driven simultaneously to perform a rotating cutting action. By the solution of arranging two mutually meshing second transmission gear structures 302 on the relay gear support 304, the third transmission gear structure 303 can maintain the power connection with the second transmission gear structure 302 and the power output gear 203 even within the preset lifting range.
