Description

Technical Field

[0001] The invention relates to the technical field of EPS foam board production, in particular to a tool for cutting a molded EPS foam board in half. Background Art

[0002] Polystyrene foam board is made of polystyrene, and its full name is polystyrene foam board, also known as foam board or EPS board. It is a white solid with a fine closed-cell structure, which is made of expandable polystyrene beads containing volatile liquid foaming agent, which are pre-heated and then heated in a mold.

[0003] In order to improve the production efficiency of formed EPS foam boards, two integrally formed foam boards that meet customer needs are often obtained by injection molding in a mold, so the foam boards heated and molded in the mold need to be cut in half.

[0004] At present, the EPS foam board cutting tool is generally to stick a positioning plate on a horizontal plate. During operation, the staff needs to align the positioning groove on the EPS foam board with the positioning plate, and then push the foam board forward until its two side edges contact the conveying roller. Due to the positioning function of the positioning plate, the conveying roller can smoothly convey the EPS foam board forward, and finally the electric heating wire in front of the support plate cuts it in half. However, there are two problems with this method of sticking the positioning plate on the horizontal plate: one is that the positioning plate is easy to fall off, and the other is that it is difficult to adjust the position of the positioning plate on the horizontal plate to adapt to different types of EPS foam boards. Therefore, we propose an improvement to the half-cutting tool for molded EPS foam boards. Summary of the invention

[0007] A further solution is that the positioning mechanism also includes a bolt, on which a first gasket is sleeved and a first nut and a second nut are threadedly connected, the first nut abuts against the surface of the tempered glass, and both ends of the positioning spring are pressed between the first gasket.

[0008] A further solution is that the tempered glass is symmetrically provided with a first movable groove and a second movable groove at both ends along the width direction, the first movable groove is used for the screw to pass through the tempered glass, and the second movable groove is used for the sponge roller to pass through the tempered glass; The screw rod is sleeved with a second gasket and threadedly connected with a fourth nut, and the fourth nut is used to press the second gasket against the upper and lower surfaces of the tempered glass.

[0009] A further solution is that it also includes a spacing adjustment mechanism, which includes two symmetrically arranged lower sliding seats and two symmetrically arranged upper sliding seats, the upper and lower ends of the screw are respectively fixedly connected to the lower sliding seat and the upper sliding seat, the upper and lower ends of the sponge roller are respectively rotatably connected to the lower sliding seat and the upper sliding seat, the first screw rod passes through the two lower sliding seats and the spiral directions are opposite, the first sliding rod passes through the upper sliding seat and slides with it; the first screw rod is driven to rotate by a first rotating motor.

[0010] A further solution is that it also includes a positioning and adjusting mechanism, which includes a third nut fixedly connected to the side of the first nut away from the tempered glass; a pull rod matched with the through hole on the third nut is arranged directly above the third nut, and the pull rod is installed at the bottom end of the telescopic rod, and the telescopic rod is installed on a slider, and the slider is symmetrically arranged along the width direction of the tempered glass and symmetrically arranged along the length direction of the tempered glass.

After the second nut no longer presses against the tempered glass, the third nuts on both sides of the width direction of the tempered glass are driven to move closer to or away from each other through the cooperation of the third rotating motor, the second screw rod, the movable seat and the second sliding block, thereby achieving the purpose of simultaneously adjusting the distance between multiple groups of positioning mechanisms to adapt to EPS foam boards of different sizes; after the distance between the positioning mechanisms is adjusted to the right position, the pull rod moves upward again and separates from the third nut. The pull rod will not affect the adjustment of the distance between the tempered glass and the heating wire. Conversely, after the distance between the tempered glass and the heating wire changes, the positioning adjustment mechanism can still adjust the distance between the positioning mechanisms.

DETAILED DESCRIPTION

[0018] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0020] See also Figure 1-Figure 6 The present invention provides a tool for cutting a molded EPS foam board in half, comprising: The tempered glass 1 comprises a plurality of tempered glass 1 spaced apart in a height direction; the tempered glass 1 has a smooth surface, can effectively resist deformation and sinking, and can maintain the flatness of the surface of the tempered glass 1 for a long time.

[0021] The positioning mechanism 5 is fixed on the tempered glass 1, and the positioning mechanism 5 includes positioning springs 501 respectively arranged on the upper surface and the lower surface of the tempered glass 1. The positioning mechanism 5 also includes a bolt 502, on which a first gasket 505 is sleeved and a first nut 503 and a second nut 504 are threadedly connected, the first nut 503 abuts against the front surface or the rear surface of the tempered glass 1, the two ends of the positioning spring 501 located on the lower surface of the tempered glass 1 are pressed between the two first gaskets 505, and the two ends of the positioning spring 501 located on the upper surface of the tempered glass 1 are pressed between the other two first gaskets 505, and the first nut 503 is between the positioning spring 501 corresponding to the lower surface of the tempered glass 1 and the positioning spring 501 corresponding to the upper surface of the tempered glass 1. Through the mutual cooperation of the first nut 503, the second nut 504 and the bolt 502, an extrusion force can be applied to the first gasket 505, so that the first gasket 505 clamps the two ends of the positioning spring 501. The positioning spring 501 is in a stretched state, so that the positioning mechanism 5 can be fixed at the designated position of the tempered glass 1. At this time, the positioning spring 501 extending along the length direction of the tempered glass 1 plays a role of positioning guide. The staff can align the positioning groove on the EPS foam board with the positioning spring 501, and then push the EPS foam board forward. Since the positioning spring 501 is in a stretched state, the positioning mechanism 5 is not easy to fall off the tempered glass 1 or to be displaced. And the positioning spring 501 can be further stretched, so as to facilitate the adjustment of the position of the positioning mechanism 5 on the tempered glass 1 to adapt to EPS foam boards of different sizes. In this embodiment, the EPS foam board is a rock slab diving platform foam board, and the rock slab diving platform foam board is used to protect the rock slab diving platform during transportation. The rock slab diving platform foam board uses its shock absorption performance to buffer the impact force of the rock slab diving platform during transportation.

[0022] See also Figure 2 and Figure 3, the two ends of the tempered glass 1 along the width direction are fixed on the screw 9, and the screw 9 is sleeved with a second gasket 11 and a fourth nut 10 is threadedly connected; by tightening the fourth nut 10, the second gasket 11 is pressed against the upper and lower surfaces of the tempered glass 1, so that the tempered glass 1 is fixed on the screw 9. It can be understood that the two ends of the tempered glass 1 are fixed on the screw 9 through the cooperation of the fourth nut 10 and the second gasket 11. After loosening the fourth nut 10, the position of each tempered glass 1 on the screw 9 can be adjusted at will without being restricted by other tempered glasses 1.

[0023] See also Figure 1 and Figure 2 A plurality of sponge rollers 2 are arranged at intervals at both ends of the tempered glass 1 along the width direction. The plurality of sponge rollers 2 located at the same end of the tempered glass 1 are arranged between the screws 9 located at the front and rear ends of the tempered glass 1. The sponge rollers 2 at the same end move synchronously under the action of the driving mechanism 7. Since the sponge material is soft, when the staff pushes the EPS foam board until the edges on both sides thereof contact the sponge rollers 2, the sponge rollers 2 of the present invention can firmly clamp the formed EPS foam board without causing damage to it, so that the sponge rollers 2 can conveniently transport the EPS foam board forward.

[0024] It should be noted that if Figure 6 As shown, the tempered glass 1 is symmetrically provided with a first movable groove 101 and a second movable groove 102 along the width direction. The first movable groove 101 is used for the screw 9 to pass through the tempered glass 1, and the second movable groove 102 is used for the sponge roller 2 to pass through the tempered glass 1. The width of the first movable groove 101 is greater than the diameter of the screw 9, so that the height position of the tempered glass 1 on the screw 9 can be adjusted. Conversely, the width of the first movable groove 101 is greater than the diameter of the screw 9, so that the fourth nut 10 needs to fix the tempered glass 1 at a certain height position of the screw 9 through the second gasket 11. In addition, the width of the second movable groove 102 is greater than the diameter of the sponge roller 2, so that the normal rotation of the sponge roller 2 will not be affected.

[0025] It should be further explained that the EPS foam board is a white solid with a fine closed-cell structure made of expandable polystyrene beads containing a volatile liquid foaming agent, which is pre-heated and then heated in a mold to form. The EPS foam board formed by the mold needs to go through stages such as injection molding and cooling molding. In order to improve the production efficiency of the formed EPS foam board, two EPS foam boards that meet customer needs are often obtained by injection molding in the mold, and then the heated and formed foam board is cut in half. Since the cutting efficiency is higher, the production efficiency of the EPS foam board can be improved. In order to achieve the half-cutting of the heated and formed foam board, the present invention is provided with a heating wire 3 directly above the tempered glass 1, and the heating wire 3 is arranged horizontally along the width direction of the tempered glass 1. The heating wire 3 corresponds to the tempered glass 1 one by one, and when the EPS foam board slides forward on the tempered glass 1, the heating wire 3 just corresponds to the middle of the EPS foam board, and the heating wire 3 after powering on can cut the foam board in half.

[0026] See also Figure 1 In order to improve the cutting effect of the heating wire 3, the two ends of the heating wire 3 are connected to the side walls of the frame 12 through the tensioning spring 4, and the end of the tensioning spring 4 away from the heating wire 3 is fixed to the frame 12. A fixing plate 13 is provided on the inner side of the frame 12, and the end of the tensioning spring 4 away from the heating wire 3 is fixed to the fixing plate 13 by screws. After removing the screws from the fixing plate 13, the height position of the tensioning spring 4 can be adjusted.

[0027] It should be noted that, since the tempered glass 1 is fixed on the screw rod 9, after loosening the fourth nut 10 on the screw rod 9, the height position of the tempered glass 1 on the screw rod 9 can be adjusted at will, and the tensioning spring 4 and the heating wire 3 can also adjust the height position. For thicker EPS foam boards, the spacing between the tempered glasses 1 can be appropriately widened; for thinner EPS foam boards, the spacing between the tempered glasses 1 can be appropriately narrowed, so that the tempered glass 1 is located as a whole at the upper position of the screw rod 9 to adapt to the height of the staff, so that the staff can align the positioning groove on the EPS foam board with the positioning mechanism 5 on each tempered glass 1 in turn and push the foam board forward.

[0028] See also Figure 1 and Figure 2In order to adapt to EPS foam boards of different sizes, the present invention is provided with a spacing adjustment mechanism 6 on the frame 12. The spacing adjustment mechanism 6 is used to adjust the spacing between the sponge rollers 2 located at both ends of the tempered glass 1 to adapt to EPS foam boards of different widths. The spacing adjustment mechanism 6 includes two symmetrically arranged lower sliding seats 603 and two symmetrically arranged upper sliding seats 604. The upper and lower ends of the sponge roller 2 are rotatably connected to the bearing seats on the lower sliding seats 603 and the upper sliding seats 604 respectively. The first screw rod 602 passes through the two lower sliding seats 603 and the spiral directions are opposite. The first sliding rod 605 passes through the upper sliding seat 604 and slides with it. The first screw rod 602 is driven to rotate by the first rotating motor 601. The first rotating motor 601 is installed on the frame 12. In addition, the sponge rollers 2 move synchronously under the action of the driving mechanism 7. There are two groups of driving mechanisms 7, corresponding to the sponge rollers 2 at both ends of the tempered glass 1. As Figure 1 and Figure 5 As shown, the driving mechanism 7 includes a second rotary motor 701, which is mounted on the lower sliding seat 603, and the output end of the second rotary motor 701 is fixedly connected to a driving wheel 702, and the bottom end of the sponge roller 2 is fixedly connected to a driven wheel 704, and the driven wheel 704 corresponds to the sponge roller 2 one by one. The lower sliding seat 603 is also rotatably connected to a plurality of transmission wheels 703, and the transmission wheels 703 and the driven wheels 704 are arranged alternately, and the belt 705 is used to drive and connect the driving wheel 702, the driven wheel 704 and the transmission wheel 703 together. Since the driving mechanism 7 is arranged on the lower sliding seat 603, when the spacing adjustment mechanism adjusts the spacing between the lower sliding seats 603, not only can the spacing between the sponge rollers 2 at both ends of the tempered glass 1 be adjusted, but also the driving mechanism 7 can be made to follow the movement.

[0029] It should be noted that the upper and lower ends of the screw rod 9 can be fixedly connected to the lower sliding seat 603 and the upper sliding seat 604 respectively, and the upper and lower ends of the screw rod 9 can also be connected to the inner side of the frame 12. This application does not make specific limitations, and all are within the protection scope of this application. When the upper and lower ends of the screw rod 9 are fixedly connected to the lower sliding seat 603 and the upper sliding seat 604 respectively, when the spacing between the lower sliding seats 603 is adjusted by the spacing adjustment mechanism, it is necessary to loosen the fourth nut 10 to prevent the tempered glass 1 from hindering the screw rod 9 from following the movement of the lower sliding seat 603. When the upper and lower ends of the screw rod 9 are connected to the inner side of the frame 12, the lower sliding seat 603 and the upper sliding seat 604 need to be provided with a strip groove for the screw rod 9 to pass through. The strip groove can prevent the lower sliding seat 603 and the upper sliding seat 604 from colliding with the screw rod 9 during the movement. At this time, since the screw rod 9 will not follow the movement, it is not necessary to loosen the fourth nut 10.

[0030] See also Figure 1 , Figure 2 and Figure 4The present invention further includes a positioning and adjusting mechanism 8, which includes a third nut 506 fixedly connected to the side of the first nut 503 away from the tempered glass 1. The third nut 506 can be welded to the first nut 503. A pull rod 809 adapted to the through hole on the third nut 506 is arranged directly above the third nut 506, and the pull rod 809 can be inserted into the through hole of the third nut 506. The pull rod 809 is installed at the bottom end of a telescopic rod 808, and the telescopic rod 808 can be an electric telescopic rod or a manual telescopic rod. The telescopic rod 808 is installed on a slider 807, and the slider 807 is symmetrically arranged along the width direction of the tempered glass 1 and symmetrically arranged along the length direction of the tempered glass 1, that is, the number of sliders 807 is set to four, and the sliders 807 are arranged in pairs, which are used to drive the positioning mechanism 5 located at one end of the tempered glass 1 to move. The slider 807 is slidably matched on the movable seat 803, and the two sliders symmetrically arranged along the length direction of the tempered glass 1 are moved closer to or away from each other under the action of the first moving mechanism. The movable seats 803 are symmetrically arranged along the width direction of the tempered glass 1, and the two movable seats 803 are moved closer to or away from each other under the action of the second moving mechanism. When the telescopic rod 808 drives the pull rod 809 to move downward, so that the bottom end of the pull rod 809 is sequentially inserted into the third nut 506 arranged along the height direction, the first moving mechanism then drives the two sliders 807 located in front and behind the tempered glass 1 to move away from each other, so that the second nut 504 no longer presses against the tempered glass 1. At this time, the third nuts 506 located on both sides of the width direction of the tempered glass 1 can be driven by the second moving mechanism to move closer to or away from each other, thereby achieving the purpose of simultaneously adjusting the spacing between multiple groups of positioning mechanisms 5 to adapt to positioning grooves on EPS foam boards of different sizes, and the operation is very convenient; after the spacing between the positioning mechanisms 5 is adjusted to the right position, the first moving mechanism drives the two sliders 807 located in front and behind the tempered glass 1 to move closer to each other, so that the second nut 504 continues to press against the tempered glass 1, and the pull rod 809 moves upward again and separates from the third nut 506. It can be understood that after the pull rod 809 is separated from the third nut 506, the pull rod 809 will not affect the adjustment of the distance between the tempered glass 1 and the heating wire 3; more importantly, when the distance between the tempered glass 1 is appropriately widened or narrowed, and when the distance between the tempered glass 1 and the heating wire 3 is changed, the bottom end of the pull rod 809 can still be inserted into the third nut 506 arranged along the height direction, that is, the positioning adjustment mechanism 8 can still adjust the distance between the positioning mechanisms 5.

[0031] It should be noted that, when the upper and lower ends of the screw 9 are respectively fixedly connected to the lower sliding seat 603 and the upper sliding seat 604, when the spacing adjustment mechanism 6 is used to adjust the spacing between the lower sliding seats 603, the pull rod 809 can be inserted into the through hole of the third nut 506, so as to limit the movement of the positioning mechanism 5 along the width direction of the tempered glass 1. Since the positioning mechanism 5 is clamped on the tempered glass 1, the tempered glass 1 can be prevented from following the movement of the screw 9 under the influence of the fourth nut 10 and the second gasket 11 on its lower surface.

[0032] Specifically, the first moving mechanism includes a fourth rotating motor 805, the output end of the fourth rotating motor 805 is fixedly connected to a third screw rod 806, the middle part of the third screw rod 806 penetrates two sliders 807 and is threadedly connected thereto, and the spiral directions are opposite. When the fourth rotating motor 805 drives the third screw rod 806 to rotate, it can drive the two sliders 807 to move closer to each other or away from each other. The second moving mechanism includes a third rotating motor 801, the movable seat 803 is in an I-shaped shape, the output end of the third rotating motor 801 is fixedly connected to a second screw rod 802, the middle part of the second screw rod 802 penetrates two movable seats 803 and is threadedly connected thereto, and the spiral directions are opposite; the middle part of the second slide bar 804 penetrates two movable seats 803 and slides with them. When the third rotating motor 801 drives the second screw rod 802 to rotate, it can drive the two movable seats 803 to move closer to each other or away from each other.

[0033] The working process of the present invention is as follows: the present invention firstly adjusts the distance between the sponge rollers 2 located at both ends of the tempered glass 1 through the distance adjustment mechanism 6 to adapt to EPS foam boards of different widths, and then adjusts the height position of the tempered glass 1 on the screw 9, as well as the height positions of the tension spring 4 and the heating wire 3, so that the distance between the tempered glass 1 is adapted to the thickness of the EPS foam board, and ensures that the heating wire 3 just corresponds to the middle of the EPS foam board, so that the heating wire 3 after power-on can cut the foam board in half; then, the distance between the multiple positioning mechanisms 5 is simultaneously adjusted through the positioning adjustment mechanism 8, so that the positioning mechanism 5 corresponds to the positioning groove on the EPS foam board; then, the working The operator aligns the positioning groove on the EPS foam board with the positioning mechanism 5 on each tempered glass 1 and pushes the foam board forward until the edges on both sides of the EPS foam board are in contact with the sponge roller 2. Since there are multiple tempered glasses 1, multiple EPS foam boards can be cut in half at the same time; the sponge roller 2 moves synchronously under the action of the driving mechanism 7 to convey the EPS foam board forward, so that the EPS foam board is cut in half by the heating wire 3. Due to the higher cutting efficiency, the present invention obtains two EPS foam boards that are integrally formed to meet customer needs through mold injection molding. Compared with a single EPS foam board that meets customer needs obtained by heat molding, the EPS foam board of the present invention has higher production efficiency.
