Description

Technical Field

[0001] The present application relates to the field of sponge cutting and processing, and in particular to a sponge special-shaped cutting machine. Background Technique

[0002] Materials such as sponges and foams will be subjected to some special-shaped cutting, such as opening corresponding circular or rectangular holes on the sponge surface for placing some fragile objects to play a protective role during transportation. Also, opening holes in the sponge can also be used for the cultivation of some plant seedlings. For this reason, corresponding cutting equipment is needed to form corresponding holes on the sponge.

[0003] Some existing sponge cuttings use an electric heating wire for cutting to obtain a smooth cutting surface. Compared with using a tool or die-cutting method, there is no need to polish the edges after cutting to process the burrs. For example, a sponge rounding machine with the publication number CN214871189U fixes the sponge on a rotatable disc, and then the electric heating wire approaches the periphery of the sponge to change the right angle at the periphery of the sponge into a rounded corner.

[0004] In order to realize the opening of holes on the sponge surface, it is also necessary to use the handheld hot cutter in the organic material shaping cutting machine with the publication number CN105666586B to lower it corresponding to the rotating sponge to form holes on the sponge.

[0005] In view of the above related technologies, using an electric heating wire to form holes on the sponge surface still has low stability due to the need for more manual intervention, and it is difficult to ensure the shape of the formed holes. Compared with the processing method of using a tool drill bit to form surface holes first and then polishing the inside of the holes, the quality of the formed sponge holes is still low. Summary of the Invention

[0006] In order to ensure the quality of the holes when using an electric heating wire to process and form sponge holes, the present application provides a sponge special-shaped cutting machine.

[0007] The sponge special-shaped cutting machine provided by the present application adopts the following technical solution.

[0008] A sponge special-shaped cutting machine includes a material box for placing the sponge and capable of rotating to make the sponge rotate synchronously and stably, an electric heating wire for forming holes on the sponge surface, a wire block detachably connected to the electric heating wire, and a vertical moving cylinder for driving the wire block to move to change the distance between the electric heating wire and the material box. The electric heating wire includes two long sections connected to the wire block and a short section located between the two ends of the two long sections away from the wire block, and the rotation axis of the material box intersects with the straight line where the short section is located.

[0009] By adopting the above technical solution, the U-shaped electric heating wire is made to be close to the center of the rotation axis of the sponge. Until the electric heating wire enters the sponge to a predetermined depth, the sponge rotates at least one circle, so that the sponge located in the formed circular hole can be separated from the whole sponge. After taking out the sponge in the hole, a sponge with a circular hole is obtained, and the inner wall of the circular hole is smooth, the circumference of the circular hole is regular, and the quality is high.

[0010] Optionally, the power rod of the vertical movement cylinder is detachably connected to a vertical movement member, the vertical movement member is detachably connected to a horizontal movement cylinder, the power rod of the horizontal movement cylinder is detachably connected to a horizontal movement member, and the wire block is detachably connected to the horizontal movement member. The moving direction of the power rod of the horizontal movement cylinder is perpendicular to the moving direction of the power rod of the vertical movement cylinder.

[0011] By adopting the above technical solution, the radius of the formed circular hole can be adjusted within a certain range.

[0012] Optionally, the horizontal movement member includes a rotary cylinder connected to the power rod of the horizontal movement cylinder and a shaft block detachably connected to the rotary shaft of the rotary cylinder and for the wire block to be detachably connected.

[0013] By adopting the above technical solution, when a rectangular hole needs to be formed, the rotary cylinder first rotates the electric heating wire by 90°, so that the moving direction of the power rod of the horizontal movement cylinder is perpendicular to the U-shaped surface of the electric heating wire. After the electric heating wire enters the sponge, the power rod of the horizontal movement cylinder extends and the sponge remains stationary to cut and form a rectangular hole, realizing the cutting and forming of more diverse special-shaped holes in the sponge.

[0014] Optionally, the wire block is detachably connected to a temperature sensor facing the electric heating wire. The temperature sensor is electrically connected to a controller, and the vertical movement cylinder is electrically connected to the controller.

[0015] By adopting the above technical solution, to ensure that before the electric heating wire contacts the sponge for cutting, when the temperature of the electric heating reaches a sufficient temperature, the vertical movement cylinder can move the electric heating wire close to the sponge to ensure the quality of the cutting surface.

[0016] Optionally, the temperature sensor is located between the two long sections. At least three temperature sensors are arranged. At least two temperature sensors correspond to the two long sections one by one, and at least one temperature sensor faces the short section.

[0017] By adopting the above technical solution, to monitor the overall temperature of the electric heating wire more comprehensively, to ensure that the temperature of each part of the electric heating wire is appropriate, and to cut the sponge with high quality.

[0018] Optionally, there is a platform on the side of the material box away from the electric heating wire. The platform is rotatably connected to the material box. The platform is rotatably connected to a vertical rod for the detachable connection of the vertical moving cylinder. The platform is detachably connected to an impurity box that can be directly faced and entered by the electric heating wire. A nozzle part that can send out compressed air flow towards the electric heating wire is slidably connected in the impurity box. The impurity box is detachably connected to a box top cylinder for driving the movement of the nozzle part.

[0019] By adopting the above technical solution, after the electric heating wire is used for a long time, the vertical rod rotates so that the electric heating wire can rotate to directly above the impurity box, and then the vertical moving cylinder drives the electric heating wire to move downward. Then, the nozzle part sprays compressed air towards the electric heating wire, so that some sponges attached to the surface of the electric heating wire can be blown off as much as possible.

[0020] Optionally, the nozzle part includes an outer ring that moves along the height direction of the electric heating wire, an inner ring that is rotatably connected and communicated with the outer ring, a nozzle that is communicated with the inner ring and can send out compressed air flow towards the electric heating wire, an air inlet pipe that is communicated with the outer ring for sending in compressed air flow, and an inner ring motor that is detachably connected to the outer ring for driving the rotation of the inner ring.

[0021] By adopting the above technical solution, a more comprehensive cleaning of the electric heating wire with compressed air flow can be carried out.

[0022] Optionally, the nozzle is inclined downward to send out air flow towards the bottom of the impurity box. A brush block is provided at the inner bottom of the impurity box. A soft brush roller that can contact the surface of the short section away from the long section is rotatably connected to the brush block. The brush block is provided with a brush motor for driving the rotation of the soft brush roller.

[0023] By adopting the above technical solution, the air flow direction is downward, so that the blown sponge impurities are not easily ejected upward from the impurity box. And the setting of the soft brush roller can clean the bottom surface of the short section that cannot be cleaned by the nozzle, so as to ensure the comprehensiveness of the overall cleaning of the electric heating wire.

[0024] Optionally, the brush block is slidably connected to the impurity box so that the soft brush roller is away from directly below the electric heating wire. The impurity box is detachably connected to a brush block cylinder for driving the movement of the brush block.

[0025] By adopting the above technical solution, when the electric heating wire is heated in the impurity box to close to the highest temperature it can bear so that the sponges attached to the surface are carbonized and fall off, the fallen sponges are not easily directly dropped onto the soft brush roller to cause damage to the bristles.

[0026] Optionally, an air suction mesh cover facing the material box and the impurity box is detachably connected to one side of the platform. The air suction mesh cover is communicated with an air suction pipe that can suck in air.

[0027] By adopting the above technical solution, during the sponge cutting process and when the electric heating wire enters the impurity box and rises to a relatively high temperature for the carbonization and shedding of the sponge, the irritating gas generated can be inhaled by the suction net cover.

[0028] In summary, the present application at least includes the following beneficial effects.

[0029] 1. The electric heating wire approximately in a U shape is close to the center of the rotation axis of the sponge. After the electric heating wire enters the sponge to a certain depth, the sponge rotates at least one circle, so that the sponge located in the formed circular hole can be separated from the whole sponge. After taking out the sponge in the hole, a sponge with a circular hole is obtained, and the inner wall of the circular hole is smooth, the circumference of the circular hole is regular, and the quality is relatively high. 2. When a rectangular hole needs to be formed, the rotating cylinder first rotates the electric heating wire by 90°, so that the moving direction of the power rod of the transverse moving cylinder is perpendicular to the U-shaped surface of the electric heating wire. After the electric heating wire enters the sponge, the power rod of the transverse moving cylinder extends and the sponge remains stationary to cut and form a rectangular hole, realizing the cutting and forming of more diverse shaped holes in the sponge.

[0032] The following further describes the present application in detail with reference to the drawings.

[0033] The embodiment of the present application discloses a sponge special-shaped cutting machine. Refer to Figure 1, including a pedestal 48 placed on the ground. The horizontally upper surface of the pedestal 48 is rotatably connected to a material box 1 with a vertical rotation axis. The material box 1 is for placing the sponge with holes to be formed. A motor can be arranged inside the pedestal 48, and a pulley and a belt are arranged at the motor output shaft and the rotation point of the material box to drive the material box 1 to rotate. There is an electric heating wire 2 above the pedestal 48 that can cut the sponge.

[0034] Referring to Figure 1 and Figure 2 , the pedestal 48 is rotatably connected to a vertical rod 49 with a vertical rotation axis. The upper part of the vertical rod 49 is detachably connected to a vertical movement cylinder 4 with a vertical power rod. The bottom end of the power rod of the vertical movement cylinder 4 is detachably connected to a vertical movement member 43. The vertical surface of the vertical movement member 43 is detachably connected to a horizontal movement cylinder 44 with a horizontal power rod. The power rod of the horizontal movement cylinder 44 is equipped with a horizontal movement member 45. The horizontal movement member 45 includes a rotary cylinder 26 detachably connected to the power rod of the horizontal movement cylinder 44 and a shaft block 27 detachably connected to the rotary shaft of the rotary cylinder 26. The rotary shaft of the rotary cylinder 26 is vertically downward. The vertical surface of the shaft block 27 is detachably connected to a wire block 3. Both ends of the electric heating wire 2 are detachably connected to the bottom surface of the wire block 3.

[0035] Referring to Figure 2 , the electric heating wire 2 can be divided into two long sections 41 connected to the bottom surface of the wire block 3 and a short section 42 at the bottom ends of the two long sections 41, so that the whole electric heating wire 2 is in a U shape. And when the extended length of the power rod of the horizontal movement cylinder 44 is zero, the center point in the length direction of the short section 42 is located on the rotation axis of the material box 1. In other embodiments, the electric heating wire 2 can also be in shapes such as an isosceles trapezoid with a shorter length and an inverted triangle with the upper base facing down, so that the shapes of the formed special-shaped holes are more diverse.

[0036] Referring to Figure 2 and Figure 3 , several temperature sensors 46 are detachably connected to the bottom surface of the wire block 3. In this embodiment, three temperature sensors 46 can be arranged. The three temperature sensors 46 are all between the upper parts of the two long sections 41. The detection ends of the two temperature sensors 46 at the edges among the three correspond to the center points of the two long sections 41 one by one. The detection end of the middle temperature sensor 46 among the three faces the center point of the upper surface of the short section 42. And the temperature sensors 46 are electrically connected to a controller 47. The controller 47 is electrically connected to the vertical movement cylinder 4, so that when the temperature of the long section 41 or the short section 42 of the electric heating wire 2 does not reach the preset value, the power rod of the vertical movement cylinder 4 will not extend, avoiding cutting the sponge when the temperature of the electric heating wire 2 is too low and moving downward.

[0037] Referring to Figure 1 and Figure 4, a waste box 31 with an open top is detachably connected to the upper surface of the frustum 48. A motor with an output shaft coaxially and detachably connected to the vertical rod 49 can be arranged inside the frustum 48, so that the vertical rod 49 can rotate by a certain angle, so that the electric heating wire 2 is moved away from directly above the material box 1 and moved to directly above the waste box 31. In this embodiment, the rotation angle of the vertical rod 49 can be 90°. A nozzle part 32 that can send a compressed air flow with a certain air pressure to the electric heating wire 2 is installed in the waste box 31. The bottom of the waste box 31 can be communicated with the inside of the frustum 48. An aluminum box with an open top can be horizontally placed inside the frustum 48 to receive the impurities falling from the cleaning of the surface of the electric heating wire 2, and the aluminum box can be conveniently taken out to dump the impurities.

[0038] Refer to Figure 4 , the nozzle part 32 includes an outer ring 34, an inner ring 35, a nozzle 36, an air inlet pipe 37 and an inner ring motor 38. The outer ring 34 is slidably connected to the inner wall of the waste box 31 in the vertical direction. A box top cylinder 33 with a power rod detachably connected to the upper surface of the outer ring 34 is detachably connected to the upper part of the waste box 31. The inner ring 35 is coaxially and rotatably connected to the inner circle of the outer ring 34. Several nozzles 36 are evenly arranged around the axis of the inner ring 35. Each nozzle 36 sends out a compressed air flow obliquely downward. The inner ring motor 38 is detachably connected to the upper surface of the outer ring 34. The inner ring motor 38 is engaged with a gear on its output shaft and a toothed ring arranged on the inner ring 35 to drive the inner ring 35 to rotate. The air inlet pipe 37 is communicated with the upper surface of the outer ring 34 and an external air compressor. The outer ring 34 and the inner ring 35 are hermetically and rotationally communicated, so that the compressed air can pass through the air inlet pipe 37, the outer ring 34 and the inner ring 35 and finally be ejected from the nozzle 36.

[0039] Refer to Figure 4 , a brush block cylinder 23 is detachably connected to the outer wall of the bottom of the waste box 31. A brush block 39 located inside the waste box 31 is detachably connected to the power rod of the brush block cylinder 23. A soft brush roller 21 with a horizontal rotation axis is rotatably connected inside the brush block 39. The soft brush roller 21 can contact the bottom of the short section 42. The brush block 39 is detachably connected to a brush motor 22 with an output shaft coaxially and detachably connected to the soft brush roller 21. Moreover, when the power rod of the brush block cylinder 23 shortens, the soft brush roller 21 moves away from directly below the electric heating wire 2 entering the waste box 31, so that when the electric heating wire 2 is heated to a relatively high temperature in the waste box 31 and the adhered sponge carbonizes and falls off, the falling high-temperature sponge material is not likely to damage the soft brush roller 21.

[0040] After the electric heating wire 2 enters the impurity box 31, first, the air nozzle 36 blows debris on the electric heating wire 2 from top to bottom. Then, the soft brush roller 21 cleans the bottom of the short section 42. Next, the soft brush roller 21 moves away from directly below the electric heating wire 2. Then, the electric heating wire 2 is heated to a relatively high temperature. Taking the electric heating wire 2 made of iron-chromium-aluminum alloy as an example, the heating temperature is between 300 and 600 °C and is maintained for 1 to 3 minutes so that the sponge adhered to the surface of the electric heating wire 2 carbonizes and falls off. Then, after waiting for the electric heating wire 2 to cool naturally to room temperature, the air nozzle 36 and the soft brush roller 21 clean the surface of the electric heating wire 2 again.

[0041] Refer to Figure 1 , a vertical suction net cover 24 is detachably connected to one side of the upper surface of the table body 48. The suction net cover 24 is detachably connected to an exhaust pipe 25 communicating with an external exhaust fan. The suction net cover 24 is located at a position on the vertical rod 49 away from the material box 1. The suction net cover 24 is directly opposite to the material box 1 and the impurity box 31 to inhale and discharge the gas generated during the process of cutting the sponge and heating the electric heating wire 2 to a high temperature in the impurity box 31 to carbonize the adhered sponge into subsequent gas treatment facilities.

[0042] The implementation principle of a sponge profiling cutting machine according to an embodiment of the present application is as follows: When a round hole needs to be formed on the upper surface of the sponge placed in the material box 1, first, the electric heating wire 2 is heated to an appropriate temperature. Then, the power rod of the vertical moving cylinder 4 extends so that the electric heating wire 2 extends into the sponge to a predetermined depth. Then, the material box 1 rotates at least one circle so that a round hole is formed in the sponge. After the electric heating wire 2 moves upward, the sponge scraps formed by cutting in the round hole of the sponge can be poured out.

[0043] When a square hole needs to be formed on the upper surface of the sponge placed in the material box 1, first, the electric heating wire 2 is heated to an appropriate temperature. At the same time, the rotary cylinder 26 drives the electric heating wire 2 to rotate 90°, and the electric heating wire 2 is away from the direction of the power rod of the transverse moving cylinder 44, and the material box 1 is adaptively replaced so that the axis of the power rod of the transverse moving cylinder 44 is perpendicular to the U-shaped surface of the electric heating wire 2. Then, the power rod of the vertical moving cylinder 4 extends so that the electric heating wire 2 extends into the sponge to a predetermined depth. Then, the power rod of the transverse moving cylinder 44 extends so that a square hole is formed in the sponge. After the electric heating wire 2 moves upward, the sponge scraps formed by cutting in the square hole of the sponge can be poured out.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
