Description

Technical Field

[0001] This utility model relates to the technical field of sponge processing and production equipment, and in particular to a non-standard sponge cutting machine. Background Technology

[0002] After the sponge is foamed and molded, it needs to be processed in terms of size and shape by cutting equipment. Sponge cutting equipment can be divided into two types according to the type of cutting blade: blade and ring blade. The ring blade sponge cutting machine is widely used because of its high cutting speed.

[0003] Currently, Chinese patent CN102390058A discloses a ring-shaped vertical blade sponge cutting machine, including a gantry frame with a sponge conveying platform below it. The gantry frame is equipped with a blade belt wheel assembly for tensioning and driving a ring-shaped blade belt. The blade belt wheel assembly includes several fixed blade belt wheels fixed to both sides of the gantry frame, and two movable blade belt wheels installed between the fixed blade belt wheels on both sides of the gantry frame. A section of the ring-shaped blade belt between the two movable blade belt wheels is the ring-shaped blade belt cutting section, which is vertical. The two movable blade belt wheels and the torsion blade mechanism can move synchronously horizontally on the gantry frame. When it is necessary to change the cutting position of the ring-shaped blade belt cutting section in the sponge width direction, this can be achieved by synchronously moving the movable blade belt wheels horizontally, without needing to synchronously move the fixed blade belt wheels, reducing inertia during movement and improving machine stability. Simultaneously, since the movable blade belt wheels only move between the fixed blade belt wheels, the size of the gantry frame can be reduced.

[0004] However, in actual production applications, the sponge in this technical solution needs to be manually aligned during transport on the conveyor platform to ensure accurate cutting position. At the same time, the lack of sponge limiting in this solution makes it easy for the sponge to deviate during cutting, which in turn leads to deviations during irregular cutting, thus affecting the cutting effect. Utility Model Content

[0005] In order to address the technical deficiencies mentioned in the background art, the purpose of this utility model is to provide a non-standard sponge cutting machine, which aims to solve the problems in the prior art where non-standard sponge cutting machines require manual positioning and cannot limit and fix the sponge, resulting in easy deviation during cutting.

The torsion blade assembly is slidably connected to the translation mechanism. The wire cutter drive assembly is connected to the annular wire cutter via a wire drive.

[0011] Preferably, the torsion knife assembly includes a mounting component, a wire knife torsion component, and a torsion knife motor. The mounting component and the torsion knife motor are fixed on the translation mechanism. The wire knife torsion component is snapped onto the annular knife wire, and the wire knife torsion component is connected to the torsion knife motor in a driving connection.

[0012] Preferably, the wire cutter drive assembly includes a wire cutter drive wheel, a wire cutter driven wheel, a movable wire cutter wheel, and a wire cutter drive component. The wire cutter drive wheel is rotatably connected within the frame, and the drive wheel and the driven wheel are driven by a ring-shaped wire cutter. Multiple driven wheels are provided, each located on one side of the frame. At least two movable wire cutter wheels are provided, located at the top and bottom of the frame, respectively, with a section between the two wheels forming the cutting end of the ring-shaped wire cutter.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention restricts the sponge by setting correction components on both sides of the conveying platform and using sensing components to detect the position of the sponge in real time. When the position of the sponge on the conveying platform changes, it can be quickly corrected and centered by the correction components. When the sponge is cut by the cutting mechanism, the correction components limit and fix the sponge on both sides, thereby effectively avoiding problems such as poor cutting effect caused by deviation during the cutting process. This improves the cutting efficiency of the irregular sponge cutting machine. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-6 The present invention provides a more detailed description of an embodiment of a non-standard sponge cutting machine.

[0029] A type of irregularly shaped sponge cutting machine, such as Figure 1 As shown, the system includes a frame 1, a cutting mechanism 2 mounted on the frame 1, a translation mechanism 3 for driving the cutting mechanism 2 to move laterally, and a conveying platform 7 located below the gantry. The two sides of the translation mechanism 3 are slidably connected to the inner sidewalls of the frame 1, and a lifting drive assembly 4 is provided at the connection between the frame 1 and the translation mechanism 3. The conveying direction of the conveying platform 7 is perpendicular to the plane of the gantry, and a correction assembly 5 for correcting deviation and limiting the placement position of the sponge is provided on the conveying platform 7. A sensing assembly 6 for detecting the conveying position of the sponge is also provided on the conveying platform 7. The sensing assembly 6 is oriented towards the conveying direction of the conveying platform 7, and the sensing assembly 6 is connected to the correction assembly 5 via an electrical signal.

[0030] Specifically, the frame 1 adopts a gantry structure with a crossbeam at the top and lifting drive components 4 on both sides. This facilitates the translation mechanism 3 driving the cutting mechanism 2 to move up and down along the lifting drive components 4, allowing the cutting mechanism 2 to adjust its cutting position according to different sponge thicknesses. Furthermore, to further restrict the sponge's position on the conveyor platform 7, correction components 5 are installed on both sides of the platform. A sensor component 6 detects the sponge's position in real time, ensuring that changes in its position on the platform are quickly corrected and aligned by the correction components 5. This also ensures that the sponge is fixed in place by the correction components 5 during cutting by the cutting mechanism 2, effectively preventing deviations during cutting and resulting in poor cutting quality.

[0031] The conveying platform 7 consists of a conveyor frame 71, a conveyor belt 72, and a drive unit for the conveyor belt 72. The drive unit for the conveyor belt 72 includes a servo motor, a drive roller, a driven roller, and a guide roller. The servo motor is fixed at one end of the conveyor frame 71, and the output end of the servo motor is connected to the drive roller. The drive roller is rotatably connected to one end of the conveyor frame 71, and the driven roller is rotatably connected to the other end of the conveyor frame 71. The drive roller and the drive roller are driven by a belt. The guide rollers are equidistantly arranged on the conveyor frame 71, and the conveyor belt 72 is sleeved on the outer surface of the drive roller, the driven roller, and the guide roller.

[0032] In this embodiment, as Figure 2 As shown, the correction assembly 5 includes a cylinder mounting base 51, a clamping cylinder 52, a telescopic push rod 53, and a pneumatic clamping plate 54; a snap-fit ​​block 55 is provided between the pneumatic clamping plate 54 and the telescopic push rod 53, the snap-fit ​​block 55 is sleeved on the telescopic push rod 53, and the snap-fit ​​block 55 is engaged with the pneumatic clamping plate 54; the cylinder mounting base 51 is fixedly mounted on both sides of the conveying platform 7 at the position corresponding to the cutter mechanism 2; and the clamping cylinder 52 is fixedly connected to the cylinder mounting base 51; the output end of the clamping cylinder 52 is connected to the telescopic push rod 53 in a transmission connection.

[0033] Specifically, when the correction component 5 restricts the position of the sponge, it stabilizes and fixes the clamping cylinder 52 through the cylinder fixing seat 51, which facilitates the quick installation of the clamping cylinder 52. Under the action of the clamping cylinder 52, the telescopic rod can be pushed forward, and under the action of the snap-fit ​​block 55, it drives the pneumatic clamping plate 54 to move forward together, so that the pneumatic clamping plates 54 on both sides can be stably fixed on both sides of the sponge. This allows the sponge to extend towards the position of the sponge during cutting, and clamp the sponge according to the preset clamping force after contacting the sponge. Since the correction component 5 is set on both sides of the conveying platform 7 and the correction components 5 on both sides are driven synchronously, the sponge can be quickly aligned under the action of the pneumatic clamping plate 54. At the same time, the pneumatic clamping plate 54 limits the sponge and effectively prevents the sponge from shifting during the cutting process.

[0034] In this embodiment, as Figure 3 As shown, the sensing component 6 includes a mounting bracket 61 and a sensor 62. The mounting bracket 61 is fixed on the conveying platform 7, and the mounting bracket 61 and the cylinder mounting seat 51 are located on the same straight line. The sensor 62 is fixed on the mounting bracket 61, and the sensor 62 is a position sensor.

[0035] Specifically, the sensing component 6 can detect the position and arrangement of the sponge during feeding in real time, thereby providing the correction component 5 with the position information of the sponge, so that the correction component 5 can make adjustments according to the offset position of the sponge; in addition to using a position sensor to detect the real-time position of the sponge, the sensor 62 can also use an optical signal sensor to detect the sponge, which is not limited in this utility model.

[0036] In this embodiment, as Figure 4 As shown, the cutting mechanism 2 includes an annular wire cutter 21, a torsion blade assembly 22 for changing the cutting direction of the annular wire cutter 21, and a wire cutter drive assembly 23 for driving the annular wire cutter 21 to rotate and cut. The annular wire cutter 21 is arranged around the torsion blade assembly 22 and the wire cutter drive assembly 23, and the distance between the upper and lower wire cutter parts of the annular wire cutter 21 is greater than the thickness of the sponge to be cut. The torsion blade assembly 22 is slidably connected to the translation mechanism 3. The wire cutter drive assembly 23 is connected to the annular wire cutter via a wire drive.

[0037] Specifically, when cutting the sponge, it is necessary not only to cut it into regular shapes but also into irregular, unique shapes. During irregular cutting, the cutting direction of the annular blade is changed by the torsion blade assembly 22, allowing it to move according to the shape being cut. The torsion blade assembly 22 includes a mounting component 221, a blade torsion component 222, and a torsion blade motor 223. The mounting component 221 and the torsion blade motor 223 are fixed to the translation mechanism 3. The blade torsion component 222 is engaged with the annular blade and is connected to the torsion blade motor 223 via a transmission connection. When changing the cutting direction of the annular blade, the torsion blade motor 223 drives the blade torsion component 222 to rotate. As the blade torsion component 222 rotates, it synchronously drives the annular blade to rotate. With the mounting component 221 fixed to the translation mechanism 3, the translation mechanism 3 moves the changed-direction annular blade to cut, thus completing the irregular cutting of the sponge.

[0038] The wire cutter drive assembly 23 includes a wire cutter drive wheel 231, a wire cutter driven wheel 232, a movable wire cutter wheel 233, and a wire cutter drive component 234. The wire cutter drive wheel 231 is rotatably connected to the frame 1, and the wire cutter drive wheel 231 and the wire cutter driven wheel 232 are driven by an annular wire cutter 21. Multiple wire cutter driven wheels 232 are provided, and the multiple wire cutter driven wheels 232 are respectively provided on both sides of the frame 1. At least two movable wire cutter wheels 233 are provided, and the two movable wire cutter wheels 233 are respectively provided at the top and bottom of the frame 1, and the section between the two movable wire cutter wheels 233 is the cutting end of the annular wire cutter. The wire cutter drive component 234 is installed at the bottom of the frame 1, and the output end of the wire cutter drive component 234 is connected to the wire cutter drive wheel 231. In order to better reduce the impact of the cutting mechanism 2, when the annular wire cutter 21 is used to cut the sponge, the transmission between the wire cutter drive wheel 231, the wire cutter driven wheel 232 and the movable wire cutter wheel 233 enables the annular wire cutter 21 to rotate at high speed, thereby achieving the purpose of cutting.

[0039] In this embodiment, as Figure 6 As shown, the translation mechanism 3 includes a linear slide 31, a slide plate 33, and a drive cylinder 34. The linear slide 31 is arranged laterally along the width direction of the conveying platform 7, and multiple linear slide rails 32 are provided on the linear slide 31. The slide plate 33 is slidably connected to the linear slide rails 32, and the slide plate 33 is fixedly connected to the torsion knife assembly 22. The drive cylinder 34 is located on one side of the linear slide 31, and the drive cylinder 34 is connected to the slide plate 33 in a transmission manner.

[0040] Specifically, the linear slide 31 spans above the conveying platform 7, and both ends of the linear platform are connected to the lifting drive assembly 4. The torsion knife assembly 22 is fixed on the linear slide 31. The direction of the cutting mechanism 2 is changed by the linear slide 31, so that it can slide left and right along the linear slide 31 under the action of the drive cylinder 34. This makes it convenient for the cutting mechanism 2 to move to the edge of the linear slide 31 after cutting, and for the cut sponge to be discharged through the conveying platform 7.

[0041] In this embodiment, the lifting drive assembly 4 includes a lifting guide rail 41, a guide block 42, a guide plate 43, and a lifting cylinder 44. The lifting guide rail 41 is axially fixed to the side wall of the frame 1. The guide block 42 is slidably connected to the lifting guide rail 41, and one side of the guide block 42 is fixedly connected to the guide plate 43. The side of the guide plate 43 opposite to the guide block 42 is fixedly connected to the linear slide 31. The lifting cylinder 44 is mounted on the frame 1, and the output end of the lifting cylinder 44 is connected to the guide block 42 in a transmission manner.

[0042] Specifically, when the lifting drive assembly 4 is working, the lifting cylinder 44 drives the guide block 42 to slide up and down along the lifting guide rail 41. At the same time, the guide block 42 drives the guide plate 43 to move together. Since the guide plate 43 is fixedly connected to the linear slide table 31, the translation mechanism 3 also moves up and down together under the action of the lifting drive assembly 4. Thus, the height of the translation mechanism 3 can be adjusted according to the thickness of the sponge, avoiding the translation mechanism 3 from conflicting with the sponge and improving the applicability of the irregular sponge cutting machine.

[0043] The working principle of this utility model:

[0044] When cutting the sponge, the sponge is conveyed by the conveying platform 7, and the position of the sponge is detected in real time by the sensing component 6. When the sponge is conveyed to the bottom of the cutting mechanism 2, the two sides of the sponge are clamped and limited by the correction component 5 to ensure that the sponge is in the middle position. When the cutting mechanism 2 starts to cut the sponge in an irregular shape, the cutting mechanism 2 can move laterally along the translation mechanism 3 under the driving action of the translation mechanism 3. The two ends of the translation mechanism 3 can drive the cutting mechanism 2 to move along the axial direction of the frame 1 under the driving action of the lifting drive component 4, so that it can adapt to the cutting of sponges of different thicknesses and meet the processing requirements of irregular sponge cutting.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
