Cutting device for producing foamed plastic products

Abstract

This application relates to the field of cutting device technology, and discloses a cutting device for producing foamed plastic products, including a support table, a U-shaped plate, a movable seat, a hollow shaft, splined cylinders, a splined shaft, cutting blades, a first driving component, a second driving component, and a third driving component. In use, controlling the second driving component rotates the splined shaft, which in turn rotates multiple splined cylinders. This, in turn, rotates multiple hollow shafts, ultimately rotating multiple cutting blades. Controlling the third driving component moves the U-shaped plate along the width and height of the support table, ultimately moving the multiple cutting blades to cut the sheet material placed on the support table. Because the multiple splined cylinders can slide relative to the multiple splined shafts, the multiple movable seats can move along the length of the support table under the drive of the first driving component. This allows adjustment of the spacing between the multiple hollow shafts, and ultimately, adjustment of the spacing between the multiple cutting blades, enabling the cutting of small pieces of sheet material of different widths.

[0017] The cutting device for producing foamed plastic products provided in this disclosure can achieve the following technical effects:

[0018] This disclosure provides a cutting device for producing foamed plastic products, comprising a support table, a U-shaped plate, movable seats, hollow shafts, splined cylinders, splined shafts, cutting blades, a first driving component, a second driving component, and a third driving component. The support table includes multiple slotted holes along its width direction, evenly distributed along the length direction of the support table, for each slotted hole to allow passage of multiple cutting blades. The U-shaped plate, located above the support table along its height direction, supports and mounts related components of the device. The movable seats, evenly distributed along the length direction of the support table between the two vertical walls of the U-shaped plate, are matched in number to the number of slotted holes, thus matching the number of hollow shafts and cutting blades with the number of slotted holes. The hollow shafts, rotatably mounted along the length direction of the support table, pass through the multiple movable seats, allowing each hollow shaft to rotate relative to its respective movable seat. Splined cylinders are installed inside the multiple hollow shafts, supporting the sliding splined shafts and transmitting torque. The splined shaft is slidably inserted through multiple splined cylinders and rotatably mounted on the two vertical walls of the girder plate. It can rotate relative to the two vertical walls of the girder plate, driving the multiple splined cylinders to rotate. Cutting blades are respectively fitted onto multiple hollow shafts, all used for cutting. A first driving component is installed between the girder plate and multiple movable seats, providing driving force to move the multiple movable seats along the length of the support platform. A second driving component is installed between the girder plate and the splined shaft, providing driving force to rotate the splined shaft. A third driving component is installed between the girder plate and the support platform, providing driving force to move the girder plate along the width and height of the support platform. Under the drive of the third driving component, multiple cutting blades can extend into multiple slotted holes.

[0019] In operation, controlling the second drive unit rotates the spline shaft, which in turn rotates multiple spline cylinders. These, in turn, rotate multiple hollow shafts, ultimately rotating multiple cutting blades. Controlling the third drive unit moves the U-shaped plate along the width and height of the support platform, ultimately moving the multiple cutting blades. This allows the multiple cutting blades to perform both rotational and linear motion, enabling them to cut the sheet material placed on the support platform. Furthermore, since the multiple spline cylinders can slide relative to the multiple spline shafts, the multiple moving seats can move along the length of the support platform under the drive of the first drive unit. This allows adjustment of the spacing between the multiple hollow shafts, and ultimately, the spacing between the multiple cutting blades, enabling the cutting of small pieces of sheet material of varying widths.

[0038] Combination Figures 1 to 6As shown, this disclosure provides a cutting device for producing foamed plastic products, including a support platform 1, a U-shaped plate 2, a movable seat 3, a hollow shaft 4, a splined cylinder 5, a splined shaft 6, cutting blades 7, a first driving member, a second driving member, and a third driving member. The support platform 1 includes multiple strip-shaped holes along its width direction, evenly distributed along the length direction of the support platform 1, for passing through multiple cutting blades 7. The U-shaped plate 2 is located above the support platform 1 along its height direction, for supporting and mounting related components of the device. The movable seats 3 are evenly distributed between the two vertical walls of the U-shaped plate 2 along the length direction of the support platform 1, the number of movable seats 3 matching the number of strip-shaped holes, so that the number of hollow shafts 4 and cutting blades 7 matches the number of strip-shaped holes. The hollow shafts 4 are rotatably inserted through the multiple movable seats 3 along the length direction of the support platform 1, and the multiple hollow shafts 4 can rotate relative to the multiple movable seats 3. Splined cylinders 5 are installed inside multiple hollow shafts 4, each supporting the slidable splined shaft 6 and transmitting torque. The splined shaft 6 slidably passes through the multiple splined cylinders 5 and is rotatably mounted on the two vertical walls of the U-shaped plate 2, allowing it to rotate relative to the two vertical walls and drive the multiple splined cylinders 5 to rotate. Cutting blades 7 are respectively fitted onto the multiple hollow shafts 4, all used for cutting. A first driving member is installed between the U-shaped plate 2 and multiple movable seats 3, providing driving force to move the multiple movable seats 3 along the length of the support platform 1. A second driving member is installed between the U-shaped plate 2 and the splined shaft 6, providing driving force to rotate the splined shaft 6. A third driving member is installed between the U-shaped plate 2 and the support platform 1, providing driving force to move the U-shaped plate 2 along the width and height of the support platform 1. Under the drive of the third driving member, the multiple cutting blades 7 can extend into the multiple strip-shaped holes.

[0039] This disclosure provides a cutting device for producing foamed plastic products. Controlling the second driving component rotates a splined shaft 6, which in turn rotates multiple splined cylinders 5. This, in turn, rotates multiple hollow shafts 4, ultimately rotating multiple cutting blades 7. Controlling the third driving component moves a U-shaped plate 2 along the width and height of a support platform 1, ultimately moving the multiple cutting blades 7. This allows the multiple cutting blades 7 to perform both rotational and linear motion, enabling the cutting of the sheet material placed on the support platform 1. Furthermore, since the multiple splined cylinders 5 can slide relative to the multiple splined shafts 6, the multiple movable seats 3 can move along the length of the support platform 1 under the drive of the first driving component. This allows adjustment of the spacing between the multiple hollow shafts 4, and ultimately, the spacing between the multiple cutting blades 7, enabling the cutting of small pieces of sheet material of different widths.

[0040] Optionally, combined Figure 1 , Figure 4 and Figure 6As shown, the first driving component includes a guide rail 8 and a slider 9. The guide rail 8 is installed along the length of the support platform 1 on the horizontal wall of the U-shaped plate 2 and is located inside the U-shaped plate 2, for supporting the sliding slider 9. The sliders 9 are evenly installed on the guide rail 8, and multiple movable seats 3 are respectively installed on multiple sliders 9, moving synchronously with the multiple sliders 9. Under the guiding and supporting action of the guide rail 8 and the multiple sliders 9, the multiple movable seats 3 are controlled to move along the length of the support platform 1.

[0041] In this embodiment, the guide rail 8 and the multiple sliders 9 together serve as guides and supports, so that the multiple movable seats 3 can move along the length direction of the support platform 1 after being controlled.

[0042] Optionally, combined Figure 1 , Figure 4 and Figure 6 As shown, the first driving component also includes a rack 10, a first motor 11, and gears 12. The rack 10 is mounted on the horizontal wall of the U-shaped plate 2 along the length of the support platform 1 and is located outside the U-shaped plate 2. The first motors 11 are respectively mounted on multiple movable seats 3, which are used to provide driving force to realize the rotational motion function. The gears 12 are respectively mounted on the rotating ends of the multiple first motors 11 and all mesh with the rack 10, together converting the rotational motion into linear motion.

[0043] In this embodiment, multiple motors are controlled to operate. Under the guidance and support of the guide rail 8 and multiple sliders 9, and the meshing action of the rack 10 and multiple gears 12, multiple movable seats 3 can move along the length direction of the U-shaped plate 2, and finally adjust the spacing of multiple cutting pieces 7.

[0044] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the first driving component also includes a limiting piece 13. The limiting pieces 13 are respectively installed at both ends of the guide rail 8.

[0045] In this embodiment, the limiting piece 13 is used to limit the movement of multiple sliders 9 from falling off the guide rail 8.

[0046] Optionally, combined Figure 1 and Figure 4 As shown, the second driving component includes a second motor 14, a driving bevel gear, and a driven bevel gear. The second motor 14 is mounted on one of the two vertical walls of the U-shaped plate 2, providing driving force to achieve rotational motion. The driving bevel gear is mounted on the rotating end of the second motor 14 and rotates under the drive of the second motor 14. The driven bevel gear meshes with the driving bevel gear, jointly transmitting the driving force and changing the direction of the force. The driven bevel gear is mounted on the hollow shaft 4, driving the hollow shaft 4 to rotate.

[0047] In this embodiment, controlling the second motor 14 to operate drives the driving bevel gear to rotate. Through the meshing of the teeth, the driven bevel gear is driven to rotate. This, in turn, drives the splined shaft 6 to rotate, ultimately driving the multiple cutting blades 7 to rotate.

[0048] Optionally, combined Figure 1 and Figure 4 As shown, the third driving component includes a first support plate 15, a first linear slide 16, a second support plate 17, and a second linear slide 18. The first support plate 15 is located above the support platform 1 along its height direction and supports the first linear slide 16. The first linear slide 16 is mounted on the first support plate 15 along the width direction of the support platform 1 and provides driving force to enable movement along the width direction of the support platform 1. The second support plate 17 is mounted on the moving end of the first linear slide 16 and supports the second linear slide 18. The second linear slide 18 is mounted on the second support plate 17 along the height direction of the support platform 1 and provides driving force to enable movement along the height direction of the support platform 1. The other of the two vertical walls of the U-shaped plate 2 is connected to the moving end of the second linear slide 18. Driven by the first linear slide 16 and the second linear slide 18, the U-shaped plate 2 moves along both the width and height directions of the support platform 1.

[0049] In this embodiment, controlling the first linear slide 16 to operate moves the second support plate 17 along the width direction of the support platform 1, ultimately moving the U-shaped plate 2 along the width direction of the support platform 1. Controlling the second linear slide 18 to operate moves the U-shaped plate 2 along the height direction of the support platform 1. Therefore, by cooperating with the first linear slide 16 and the second linear slide 18, the function of multiple cutting blades 7 moving freely in the vertical plane can be realized to complete the feeding.

[0050] Optionally, combined Figure 1 and Figure 4 As shown, the third driving component also includes a support shaft 19. The support shaft 19 is installed between the support platform 1 and the first support plate 15.

[0051] In this embodiment of the disclosure, the support shaft 19 is used to drive the relative position of the support platform 1 and the first support plate 15, and to adjust the distance between the support platform 1 and the first support plate 15.

[0052] Optionally, combined Figure 1 and Figure 2 As shown, it also includes a first bearing 20. The first bearing 20 is respectively installed between multiple movable seats 3 and multiple hollow shafts 4.
