Description

Technical Field

[0001] This utility model belongs to the field of foundation treatment technology, and more specifically, it relates to a cutting device for plastic drainage boards. Background Technology

[0002] Plastic drainage boards are strip-shaped composite geosynthetic materials. Their cross-sectional structure typically consists of a central plastic core board and an outer non-woven geotextile filter membrane. The core board provides support and drainage channels, while the filter membrane plays a crucial role in permeability and soil filtration, allowing water infiltration while preventing soil particles from clogging the core board.

[0003] In the vertical drainage construction process for soft soil foundation reinforcement, the site is first leveled and a sand cushion layer is laid. Then, a special inserting machine is used to insert the plastic drainage board connected to the pipe shoe into the soft soil foundation until the design elevation is reached. Next, the sleeve is pulled out and the plastic drainage board is left in the soil. Finally, the plastic drainage board is cut and the exposed part of the plastic drainage board above the ground is buried. The upper load is used to make the water in the soil flow into the sand cushion layer along the plastic drainage board and then be discharged, thereby accelerating the consolidation of the foundation.

[0004] However, cutting plastic drainage boards typically relies on manual cutting with knives. This method not only increases the workload for operators but also poses certain safety hazards. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for plastic drainage boards, which is designed to automatically cut plastic drainage boards.

When the plastic drainage board is clamped by the two clamping ends, the cutting assembly moves, and the driving part drives the cutting part to perform a reciprocating cutting action to cut the plastic drainage board.

[0007] In one possible implementation, the cutting component includes: The cutting seat is drivably and horizontally slidably mounted on the bracket; A cam is rotatably connected to the cutting seat; The cutting tool is horizontally slidably connected to the cutting seat, and the sliding direction is perpendicular to the moving direction of the cutting seat; the cutting tool has an elastic degree of freedom to move toward the cam, so that the end of the cutting tool always abuts against the outer peripheral surface of the cam; The first motor is fixedly connected to the cutting seat, and its output end is connected to the cam; The cutting tool constitutes the cutting part, and the cam and the first motor constitute the driving part; when the first motor drives the cam to rotate, the cam drives the cutting tool to perform a reciprocating cutting action.

[0008] In one possible implementation, the cutting component further includes: A drive screw is rotatably connected to the bracket and threadedly connected to the cutting seat; the drive screw is horizontally positioned. The first guide rod is fixedly connected to the bracket and slidably connected to the cutting seat; the first guide rod is parallel to the drive screw. The second motor is fixedly connected to the bracket, and its output end is connected to the drive screw.

[0009] In one possible implementation, the cutting tool includes: Two sliders are slidably connected to both sides of the cutting seat; a return spring is connected between one slider and the cutting seat, and the other slider abuts against the cam; The cutting blade is fixedly connected between the two sliders.

[0010] In one possible implementation, a reinforcing rib is fixedly connected to the cutting blade along its length, the reinforcing rib extending from one of the sliders to the other.

[0011] In one possible implementation, the cutting tool has two opposing cutting edges.

[0012] In one possible implementation, the slider abutting against the cam has an arcuate surface that is adapted to the outer peripheral surface of the cam.

[0013] In one possible implementation, the clamping element includes: A double-ended screw is rotatably connected to the bracket and has two threaded segments with opposite directions of rotation.

[0015] In one possible implementation, gaskets are fixedly connected to opposite sides of both clamping plates.

[0016] This utility model provides a cutting device for plastic drainage boards. Compared with existing technologies, its advantages are as follows: After the insertion machine inserts the plastic drainage board into the soft soil foundation and reaches the design elevation, the operator starts the device. The two clamping ends of the clamping component are driven closer together, tightly clamping the exposed part of the plastic drainage board to ensure its fixed position. Subsequently, the cutting component slides horizontally under the drive of the drive unit, while the cutting unit performs a reciprocating cutting motion, thereby cutting the plastic drainage board.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Please see Figure 1 This invention provides a cutting device for plastic drainage boards. The device includes a support 1, a clamping member 3, and a cutting assembly 5. The support 1 is mounted on a board inserter 2. The clamping member 3 is disposed on the support 1. The clamping member 3 has two drivable clamping ends that can move closer or further apart to clamp the plastic drainage board 4. The cutting assembly 5 is drivably and horizontally slidably disposed on the support 1. The cutting assembly 5 has a cutting part and a driving part for driving the cutting part to move horizontally reciprocally. When the plastic drainage board 4 is clamped by the two clamping ends, the cutting assembly 5 moves, and the driving part drives the cutting part to perform a reciprocating cutting action to cut the plastic drainage board 4.

[0024] After the inserter 2 inserts the plastic drainage board 4 into the soft soil foundation and pulls out the sleeve, leaving the plastic drainage board 4 in the soil, the two clamping ends of the clamping member 3 are driven to move closer together, thereby clamping the plastic drainage board 4 at the designated cutting position. Stable clamping prevents displacement of the plastic drainage board 4 during the cutting process. Subsequently, the cutting assembly 5 is driven to slide horizontally, while its drive unit continuously drives the cutting unit to perform a high-frequency reciprocating cutting motion, cutting the clamped and fixed plastic drainage board 4. After cutting, the clamping ends of the clamping member 3 move away from each other, releasing the cut plastic drainage board 4 for subsequent burial of the exposed portion.

[0025] The mechanical clamping of clamping component 3 replaces manual hand-held fixing, eliminating the labor intensity of operators needing to continuously exert force to fix the plastic drainage board 4. It also ensures the accuracy of the cutting position through stable clamping force, avoiding cutting deviation caused by uneven force or hand tremors during manual fixing, thus ensuring a smooth cut. The reciprocating cutting of cutting component 5 replaces manual single-force cutting. The continuous reciprocating motion ensures thorough cutting, avoiding incomplete cutting and repeated cutting caused by insufficient force or blade angle deviation during manual cutting. It also eliminates the safety hazard of the blade slipping and injuring the hand during manual hand-held cutting.

[0026] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The cutting assembly 5 includes a cutting base 51, a cam 52, a cutter 53, and a first motor 54. The cutting base 51 is drivably and horizontally slidably mounted on the support 1. The cam 52 is rotatably connected to the cutting base 51. The cutter 53 is horizontally and slidably connected to the cutting base 51, with its sliding direction perpendicular to the moving direction of the cutting base 51. The cutter 53 has an elastic degree of freedom to move toward the cam 52, ensuring that the end of the cutter 53 always abuts against the outer peripheral surface of the cam 52. The first motor 54 is fixedly connected to the cutting base 51, and its output end is connected to the cam 52. The cutter 53 constitutes the cutting part, and the cam 52 and the first motor 54 constitute the driving part. When the first motor 54 drives the cam 52 to rotate, the cam 52 drives the cutter 53 to perform a reciprocating cutting action.

[0027] The cutting seat 51 of the cutting assembly 5 is drivably and horizontally slidably mounted on the bracket 1. When cutting is required, the cutting seat 51 first moves horizontally to the vicinity of the cutting position of the plastic drainage board 4. Then, the first motor 54 starts, and its output end drives the cam 52 to rotate on the cutting seat 51. As the cam 52 rotates, the change in the radius of its outer circumference will push the cutter 53 to move back and forth along the sliding direction, thereby achieving efficient cutting of the clamped and fixed plastic drainage board 4.

[0028] In some possible embodiments, please refer to Figure 1 and Figure 2 The cutting assembly 5 also includes a drive screw 55, a first guide rod 56, and a second motor 57. The drive screw 55 is rotatably connected to the bracket 1 and threadedly connected to the cutting seat 51. The drive screw 55 is horizontally positioned. The first guide rod 56 is fixedly connected to the bracket 1 and slidably connected to the cutting seat 51. The first guide rod 56 is parallel to the drive screw 55. The second motor 57 is fixedly connected to the bracket 1, and its output end is connected to the drive screw 55.

[0029] When it is necessary to adjust the horizontal position of the cutting seat 51, the second motor 57 starts, and its output end drives the drive screw 55 to rotate stably around its own axis. Since the cutting seat 51 is threadedly engaged with the drive screw 55 and cannot rotate with the drive screw 55 under the restriction of the first guide rod 56, the rotational motion of the drive screw 55 is converted into the horizontal linear motion of the cutting seat 51 along the direction of the first guide rod 56, thereby controlling the cutting seat 51 to move to the designated cutting position of the plastic drainage board 4.

[0030] The screw drive mechanism consisting of the drive screw 55 and the second motor 57 has the characteristics of high transmission accuracy and accurate displacement control. The movement distance of the cutting seat 51 can be precisely controlled by controlling the number of rotations of the second motor 57, ensuring that the cutter 53 can be aligned with the preset cutting position of the plastic drainage plate 4 each time it is cut.

[0031] In some possible embodiments, please refer to Figure 3 The cutting tool 53 includes two sliders 531 and a cutting blade 533. The two sliders 531 are slidably connected to both sides of the cutting base 51. A return spring 532 connects one slider 531 to the cutting base 51, and the other slider 531 abuts against a cam 52. The cutting blade 533 is fixedly connected between the two sliders 531.

[0032] One slider 531 abuts against the outer peripheral surface of the cam 52, while a return spring 532 connects the other slider 531 to the cutting seat 51. The return spring 532 is always in a slightly pre-compressed state, providing the slider 531 with an elastic force toward the cam 52. When the first motor 54 drives the cam 52 to rotate, the thrust of the cam 52 and the elastic force of the return spring 532 work together to enable the two sliders 531 to drive the cutting blade 533 to move stably back and forth in the horizontal direction, thus completing the cutting of the plastic drainage board 4.

[0033] In some possible embodiments, please refer to Figure 3 A reinforcing rib 534 is fixedly connected to the cutting blade 533 along its length direction. The reinforcing rib 534 extends from one slider 531 to another slider 531.

[0034] When the two sliders 531 drive the cutting blade 533 to reciprocate cutting the plastic drainage board 4, the cutting blade 533 will be subjected to the reaction force of the plastic drainage board 4. The cutting blade 533 is prone to bending deformation due to the concentrated force. The rigidity of the reinforcing rib 534 itself will resist the bending tendency of the cutting blade 533, ensuring that the cutting blade 533 always remains straight.

[0035] In some possible embodiments, please refer to Figure 3The cutting blade 533 has two opposing cutting edges. The two cutting edges of the cutting blade 533 are located on both sides of the cutting seat 51, so that the cutting blade 533 can cut the plastic drainage board 4 during the reciprocating movement of the cutting seat 51, which greatly improves the cutting efficiency and ensures that the cutting blade 533 has cutting capability in both the outward and return strokes of the cutting seat 51.

[0036] In some possible embodiments, please refer to Figure 3 The slider 531 that abuts against the cam 52 has an arc-shaped surface 5311, which is adapted to the outer peripheral surface of the cam 52.

[0037] When the first motor 54 drives the cam 52 to rotate on the cutting seat 51, the slider 531 that abuts against the cam 52 maintains contact with the outer peripheral surface of the cam 52 through the arc surface 5311. During the rotation of the cam 52, the contact point between the arc surface 5311 and the outer peripheral surface of the cam 52 will move smoothly with the rotation of the cam 52, avoiding the slider 531 from getting stuck due to irregular contact surface.

[0038] In some possible embodiments, please refer to Figure 1 , Figure 2 and Figure 3 The clamping component 3 includes a double-ended screw 31, a second guide rod 32, two clamping plates 33, and a third motor 34. The double-ended screw 31 is rotatably connected to the bracket 1 and has two threaded segments with opposite directions of rotation. The second guide rod 32 is fixedly connected to the bracket 1 and parallel to the double-ended screw 31. The two clamping plates 33 are threadedly connected to the two threaded segments respectively, and are also slidably connected to the second guide rod 32. The third motor 34 is fixedly connected to the bracket 1, and its output end is connected to the double-ended screw 31. The clamping plates 33 form the clamping ends.

[0039] After the inserter 2 completes the insertion of the plastic drainage board 4 and the removal of the sleeve, the plastic drainage board 4 is in a state to be cut. At this time, the third motor 34 starts, and its output end drives the double-headed screw 31 to rotate around its own axis. Since the two clamping plates 33 are respectively connected to the threaded sections with opposite directions of rotation, and cannot rotate with the double-headed screw 31 under the restriction of the second guide rod 32, the rotational motion of the double-headed screw 31 is converted into the relative motion of the two clamping plates 33 along the direction of the second guide rod 32.

[0040] As the third motor 34 continues to operate, the two clamping plates 33 gradually approach the plastic drainage plate 4 until they are in close contact with the surface of the plastic drainage plate 4 and a stable clamping force is applied. At this point, the third motor 34 stops operating, and the clamping plates 33 remain in a clamping state, providing fixation for the cutting action of the cutting assembly 5. After cutting is completed, the third motor 34 rotates in the reverse direction, driving the double-headed screw 31 to rotate in the reverse direction, causing the two clamping plates 33 to move away from each other along the second guide rod 32, releasing the cut plastic drainage plate 4, and completing one clamping cycle.

[0041] In some possible embodiments, please refer to Figure 1 and Figure 2 Each clamping plate 33 has a notch 331 extending horizontally. The cutting seat 51 passes through the notch 331 and moves along the extension direction of the notch 331 when performing the cutting action.

[0042] When the third motor 34 drives the two clamping plates 33 to approach each other and clamp the plastic drainage plate 4, the cutting seat 51 has already penetrated the notch 331 of the two clamping plates 33. The notch 331 provides clearance for the cutting seat 51, so that the clamping plates 33 will not collide with the cutting seat 51 when approaching the plastic drainage plate 4. After the clamping plates 33 have finished clamping the plastic drainage plate 4, the second motor 57 drives the drive screw 55 to rotate, causing the cutting seat 51 to move horizontally along the extension direction of the notch 331. At the same time, the cutting part on the cutting seat 51 performs a reciprocating cutting action. Since the extension direction of the notch 331 is consistent with the movement direction of the cutting seat 51, the cutting seat 51 is always within the notch 331 during the movement and will not be blocked by the clamping plates 33.

[0043] In some possible embodiments, please refer to Figure 2 Each of the two clamping plates 33 has a gasket 332 fixedly connected to one side of the opposite side.

[0044] The gasket 332 is made of a material with a certain degree of elasticity and friction, such as rubber or elastic plastic. When the third motor 34 drives the two clamping plates 33 to approach each other, the gasket 332 contacts the plastic drainage plate 4 and produces a stable clamping effect on the plastic drainage plate 4.

[0045] In summary, the cutting device for plastic drainage boards provided by this utility model, compared with the prior art, allows for more efficient operation. After the insertion machine 2 inserts the plastic drainage board 4 into the soft soil foundation and reaches the design elevation, the operator starts the device. The two clamping ends of the clamping member 3 are driven closer together, tightly clamping the exposed part of the plastic drainage board 4 to ensure its fixed position. Subsequently, the cutting component 5 slides horizontally under the drive of the driving unit, while the cutting unit performs a reciprocating cutting motion, thereby cutting the plastic drainage board 4. This design replaces the traditional manual cutting method with a knife, significantly reducing the labor intensity of the operator and eliminating the safety risks associated with directly holding a knife, such as cuts or misoperation. Simultaneously, automated clamping and cutting improve construction efficiency.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
