Specific implementation
[0029] In order to make the technical personnel in the field better understand the technical scheme of the utility model, the utility model will be further introduced in detail below in conjunction with the drawings.
[0030] As Figures 1-7 Indicated, a kind of EPDM sponge cutting device, including the cutting table 1 for feeding sponge and the gantry 2 across on cutting table 1, and is provided with cutting unit, including rotating piece 3 for correcting sponge deviation;
[0031] Slidingly set on sliding block 5 on gantry 2 in vertical direction, rotating piece 3 is rotationally arranged on sliding block 5, and sliding block 5 is active with rotating piece 3 deflection;
[0032] Movable plate 6 symmetrically and slidingly set on the both sides of cutting table 1, it is used to level sponge.
[0033] Specifically, multiple rotating pieces 3 are linearly arrayed along the width direction of cutting table 1, and are all fixedly arranged on rotating rod 4, and rotating rod 4 both ends are rotationally arranged on sliding block 5, and cutting unit in gantry 2 cuts sponge along width direction, above-mentioned cutting unit is the technical common sense known to those skilled in the art, and here is not repeated.
[0034] Further, as Figure 1 Reference, then sponge moves along the length direction of cutting table 1, and moves from left side to right side, which direction is feeding direction. The vertical distance between rotating rod 4 and sponge is less than the length of rotating piece 3, so that rotating piece 3 keeps skew state and end portion is in abutment with the upper surface of sponge, because the length direction of rotating piece 3 is consistent with the length direction of cutting table 1, in the process of sponge feeding, the pressure exerted on sponge by rotating piece 3 end portion can stabilize the feeding direction of sponge, and plays a guiding role. As Figure 6As shown, when the sponge is normally fed, the upper surface of the sponge and the end of the rotating member 3 are in sliding friction, and at this time, the propulsion force F of the sponge and the resistance f of the rotating member 3 to the sponge are coaxial and opposite in direction, the propulsion force F is greater than the resistance f, and the sponge is normally fed between the cutting table 1 and the end of the rotating member 3; when the sponge deviates, as shown in the figure Figure 7 As shown, the propulsion force F of the sponge is no longer coaxial with the resistance f of the rotating member 3, and an angle is formed between the propulsion force F of the sponge and the resistance f, at this time, the propulsion force F can be divided into a component force F1 consistent with the propulsion direction and a component force F2 perpendicular to the propulsion direction, wherein F1 is less than the propulsion force F, so that the resistance f is greater than the component force F1, that is, the deviated sponge can be stopped by the end of the rotating member 3, and the sponge in the deviated state is avoided to be cut.
[0035] During the feeding of the sponge, the rotating member 3 is slightly deflected by the upper surface of the sponge, and is turned from the inclined state to the vertical state, and drives the slider 5 to move upward, avoiding the sponge from being deformed due to excessive extrusion of the rotating member 3, and the movable plates 6 can be driven to move by driving motors or telescopic electric rods arranged on both sides of the cutting table 1, or other driving units known to those skilled in the art, so that the two movable plates 6 always move close to or away from each other along the width direction of the cutting table 1, and the extrusion and pulling force generated during the closing and opening process can make the sponge receive forces in opposite directions on both sides, so as to correct the deviation.
[0036] In the above-mentioned technology, during the feeding of the sponge, the pressure applied by the end of the rotating member 3 to the sponge can stabilize the feeding direction of the sponge, and when the sponge deviates, the deviated sponge can be stopped by the end of the rotating member 3, and the two movable plates 6 always move close to or away from each other along the width direction of the cutting table 1 to correct the deviation of the sponge.
[0037] As a further embodiment of the utility model, the gantry 2 includes a back side consistent with the feeding direction and a front side opposite to the back side, and the movable plate 6 is arranged close to the front side.
[0038] Specifically, with Figure 1 reference to the figure, the gantry 2 on the left side of the image is the front side. The movable plate 6 is arranged on the left side of the gantry 2, so that the sponge is first extruded or pulled in the width direction by the two movable plates 6, so that the forces on both sides of the sponge are consistent but opposite in direction, and the sponge is corrected after entering the gantry 2 for cutting.
[0039] As a further embodiment of the utility model, the first spring 61 for keeping the movable plate 6 in a predetermined position is further provided.
[0040] Specifically, the first spring 61 is located between the movable plate 6 and the gantry 2, and maintains the movable plate 6 in a predetermined position by the elastic force of the first spring 61, wherein the two movable plates 6 are symmetrical about the center line of the cutting table 1 and have the minimum distance, and then the driving motor or the electric telescopic rod drives the two movable plates 6 to move close to or away from each other, so as to ensure that the force on both sides of the sponge is always equal and opposite in direction.
[0041] As further provided in another embodiment of the utility model, a height-adjustable pressing plate 8 is slidably arranged on the movable plate 6.
[0042] Specifically, the adjusting bolt 7 is threadedly connected to the movable plate 6, and the end of the adjusting bolt 7 is fixedly connected to the pressing plate 8, and the four corners of the pressing plate 8 are provided with convex columns slidably matched with the movable plate 6. The adjusting bolt 7 can be rotated according to the thickness of the sponge of different specifications, so that the adjusting bolt 7 moves in the vertical direction and drives the height of the pressing plate 8 to change, and when the pressing plate 8 abuts against the sponge without deforming the sponge, the height is appropriate.
[0043] As further provided in another embodiment of the utility model, a rotating wheel 81 abutting against the sponge is rotatably arranged on the pressing plate 8.
[0044] Specifically, the rotating wheel 81 is located in the middle of the pressing plate 8, and the vertical projection length of the rotating wheel 81 is consistent with the length direction of the cutting table 1. When the sponge is normally fed, the rotating wheel 81 rotates driven by the sponge, at this time, the rolling friction force exists between the sponge and the rotating wheel 81, and the pressing plate 8 will not affect the feeding of the sponge, while when the pressing plate 8 is driven by the movable plate 6 to move in the width direction, the rotating wheel 81 will drive the sponge to move in the width direction through the sliding friction force of the circular arc surface on the upper surface of the sponge, and correct the deviation of the sponge, so that the sponge is only adjusted in the width direction by the pressing plate 8 and the rotating wheel 81, and is pressed by the pressing plate 8 during the feeding of the sponge, thereby avoiding the problem that the sponge appears local bulging or wave shape.
[0045] As further provided in another embodiment of the utility model, a plurality of cone pulleys 32 are rotatably arranged at the end of the rotating member 3.
[0046] Specifically, the cone pulley 32 is composed of two spindle-shaped structures connected end to end, and has a shape of concave in the middle and convex on both sides as shown in the figure. Figure 3 Some sponges are provided with continuous notches on the upper surface in the length direction for convenience, and the design of the cone pulley 32 can correspondingly match the notches, thereby improving the guiding effect of the cone pulley 32 on the special-shaped sponge.
[0047] As further provided in another embodiment of the utility model, a fixed clamping tooth 34 for limiting the rotation of the cone pulley 32 is further provided, and the cone pulley 32 is pushed by the sponge in the limited state to make the rotating member 3 deflect.
[0048] Specifically, the fixed clamping tooth 34 is fixedly arranged at the end of the rotating member 3, and the wheel set composed of a plurality of bevel gears 32 is arranged at the end of the rotating member 3 in the axial direction, the bevel gear 32 is fixedly arranged relative to the wheel set, and the rotating clamping tooth 33 fixedly arranged on the wheel set is clamped with the fixed clamping tooth 34. In the default state, the rotating clamping tooth 33 and the fixed clamping tooth 34 are clamped with each other, when the bevel gear 32 is driven by the friction force on the upper surface of the sponge, the wheel set drives the rotating clamping tooth 33 to rotate, the teeth of the rotating clamping tooth 33 slide along the inclined tooth surface of the fixed clamping tooth 34, so that the wheel set slides in the axial direction, so that the rotating clamping tooth 33 is disengaged from the fixed clamping tooth 34, and the wheel set can normally rotate.
[0049] As further provided in another embodiment of the utility model, the bevel gear 32 is provided with a second spring 31 for moving the bevel gear 32 to be close to the fixed clamping tooth 34.
[0050] Specifically, in the default state, the second spring 31 pulls the wheel set composed of the bevel gear 32 to be close to the fixed clamping tooth 34, so that the rotating clamping tooth 33 is tightly attached to the fixed clamping tooth 34, and the rotation of the bevel gear 32 is limited at this time. In the normal feeding process of the sponge, the pushing force F is relatively large, and the friction force of the pushing force F on the bevel gear 32 drives the wheel set to rotate, as shown in the figure, the rotating clamping tooth 33 rotates and the teeth slide along the inclined tooth surface of the fixed clamping tooth 34, and the wheel set can slide in the axial direction to overcome the elastic force of the second spring 31, so that the rotating clamping tooth 33 is disengaged from the fixed clamping tooth 34. Figure 6
[0051] But when the sponge is inclined, there is an angle between the pushing force F on the sponge and the rotation direction of the bevel gear 32 at this time, so that the pushing force F transmitted to the bevel gear 32 is the component force F1, as shown in the figure, F1 is less than F, so the wheel set cannot overcome the elastic force of the second spring 31, so that the rotating clamping tooth 33 is still in the state of tightly attaching to the fixed clamping tooth 34, and the wheel set is limited and cannot rotate. At this time, the sliding friction force exists between the bevel gear 32 and the upper surface of the sponge, so that when the sponge continues to feed, the bevel gear 32 will not rotate to avoid, but will remain in the original position, and the bevel gear 32 can pass through only by being squeezed by the sponge at this time, so that the end of the rotating member 9 is squeezed by the sponge, so that the rotating member 9 as a whole deviates from the inclined state to the vertical state, and the sliding block 5 moves upward. Figure 7
[0052] As further provided in another embodiment of the utility model, the movable plate 6 moves synchronously with the rotating member 3.
[0053] Specifically, the movement amount of the sliding block 5 can be detected by arranging a sensing device on the sliding block 5, and the sensing device is electrically connected with the driving unit for controlling the movable plates 6. When the height of the sliding block 5 rising exceeds a threshold value, the driving unit is automatically started to make the two movable plates 6 close to or away from each other, or an infrared detection device is arranged at a fixed position above the sliding block 5, and the infrared detection device is electrically connected with the driving unit for controlling the movable plates 6, the sliding block 5 will trigger the infrared detection device during the upward movement, thereby starting the driving unit, or other triggering modes known to those skilled in the art.
[0054] As further provided by the utility model, the movable plate 6 is fixedly provided with a transmission member 9 which is in sliding cooperation with the sliding block 5.
[0055] Specifically, the sliding block 5 is provided with an inclined surface, and when the sliding block 5 rises, the transmission member 9 is pushed by the inclined surface to slide away from the cutting table 1, at this time, the second spring 31 is squeezed to store energy, the two movable plates 6 are away from each other and simultaneously pull the two sides of the sponge to correct the deviation, then the position of the sponge is corrected, the intensity of the pushing force F is increased, and the friction force between the pushing force F on the sponge and the bevel gear 32 drives the wheel set to rotate, when the wheel set can naturally rotate, the sliding friction force of the sponge on the wheel set becomes smaller rolling friction force, so that the end of the rotating member 3 is no longer deflected by the sliding friction force, the sliding block 5 falls under the action of gravity, and the energy stored in the second spring 31 is released to drive the two movable plates 6 to move close to the center to correct the deviation of the sponge again.
[0056] Working principle: in the default state, the second spring 31 pulls the wheel set composed of the bevel gear 32 to close to the fixed tooth 34, so that the rotating tooth 33 is in close contact with the fixed tooth 34, at this time, the rotation of the bevel gear 32 is limited. In the normal feeding process of the sponge, the intensity of the pushing force F is large, the friction force between the pushing force F on the sponge and the bevel gear 32 drives the wheel set to rotate, as shown in FIG. 8, the rotating tooth 33 rotates and the teeth slide along the inclined tooth surface of the fixed tooth 34, the wheel set can slide along the axial direction to overcome the elastic force of the second spring 31, so that the rotating tooth 33 is disengaged from the fixed tooth 34. Figure 6
[0057] The sponge drives the rotating wheel 81 to rotate, at this time, the rolling friction force exists between the sponge and the rotating wheel 81, and the pressing plate 8 does not affect the feeding of the sponge.
[0058] However, when the sponge is inclined, there is an angle between the pushing force F on the sponge and the rotation direction of the bevel gear 32, so that the intensity of the pushing force F transmitted to the bevel gear 32 is the component force F1, as shown in FIG. 9, the rotating tooth 33 rotates and the teeth slide along the inclined tooth surface of the fixed tooth 34, the wheel set can slide along the axial direction to overcome the elastic force of the second spring 31, so that the rotating tooth 33 is disengaged from the fixed tooth 34. Figure 7 As shown, F1 is less than F, so the wheel set cannot overcome the elastic force of the second spring 31, so that the rotating clamping tooth 33 and the fixed clamping tooth 34 are still in the state of close contact, and the wheel set is limited and cannot rotate. At this time, the sliding friction force exists between the bevel gear 32 and the upper surface of the sponge, so that when the sponge continues to feed, the bevel gear 32 does not avoid rotating, but remains in the original position and needs to be pushed by the sponge to pass through. At this time, the end of the rotating part 9 is pushed by the sponge, so that the rotating part 9 is inclined to the vertical state as a whole, the sliding block 5 moves upward, and the sliding block 5 pushes the transmission part 9 through the inclined surface when the sliding block 5 rises, so that the transmission part 9 slides away from the cutting table 1, at this time, the second spring 31 is pressed and stored, the two movable plates 6 are away from each other and simultaneously pull the two sides of the sponge to correct the deviation, and then the position of the sponge is corrected, the pushing force F is increased, and the friction force of the pushing force F on the bevel gear 32 is driven to rotate the wheel set, when the wheel set naturally rotates, the sliding friction force of the sponge on the wheel set becomes smaller, so that the end of the rotating part 3 is no longer affected by the sliding friction force and is deflected, the sliding block 5 falls under the action of gravity, and the storage of the second spring 31 is released, so as to drive the two movable plates 6 to approach the center again, and correct the deviation of the sponge again.
[0059] When the pressing plate 8 is driven by the movable plate 6 to move in the width direction, the rotating wheel 81 drives the sponge to move in the width direction through the sliding friction force of the arc surface on the upper surface of the sponge, and corrects the deviation of the sponge, so that the sponge is only adjusted in the width direction by the pressing plate 8 and the rotating wheel 81, and is pressed by the pressing plate 8 during the feeding process of the sponge, so as to avoid the problem that the sponge appears local bulge or wave shape.
[0060] The above only describes some exemplary embodiments of the present application in a descriptive manner, without doubt, for ordinary skilled in the art, the described embodiments can be modified in various ways without departing from the spirit and scope of the present application. Therefore, the above drawings and description are illustrative in nature and should not be understood as limiting the scope of protection of the present application.
