Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a shearing machine for calcium sulfate-based antistatic flooring. Background Technology

[0002] Calcium sulfate-based antistatic flooring is widely used in the raised floor sector due to its numerous advantages, including environmental friendliness, fire resistance, high strength, and flatness. Especially in developed countries and regions, its usage has surpassed that of composite flooring, making it the preferred choice for designers. This flooring plays a crucial role in many industries, including aerospace, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical appliances, and interior decoration, providing high-quality flooring solutions for these industries' spatial environments.

[0003] Shearing machines, as essential equipment in the metal processing industry, are indispensable in the processing of calcium sulfate-based antistatic flooring. Through a moving upper blade and a fixed lower blade, and utilizing a suitable blade gap, they apply shearing force to plates of varying thicknesses, achieving the separation of the plates to the required dimensions.

[0004] However, some existing shearing machines lack a dedicated material collection structure when shearing calcium sulfate-based antistatic flooring. This causes the sheared boards to fall freely due to gravity, resulting in a large number of board fragments and finished products scattered around the equipment. This not only makes the work area cluttered and increases the workload for workers to clean up, but also may affect the safety of the operating space and the smoothness of the work process due to the accumulation of items on the ground. Therefore, there is a need to design a shearing machine specifically for calcium sulfate-based antistatic flooring.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] This utility model provides a shearing machine for calcium sulfate-based antistatic flooring, which solves the problem that some shearing machines lack a material collection structure when shearing calcium sulfate-based antistatic flooring, causing the boards and fragments to scatter, resulting in a messy work area and increased subsequent cleaning workload.

[0007] This utility model embodiment adopts the following technical solution: a shearing machine for calcium sulfate-based antistatic flooring. It includes an operating box and a limiting component. The limiting component includes a collection box installed inside the operating box. A guide plate for guiding the sheared board material is installed inside the operating box, and the guide plate is located on one side of the collection box. Clamping plates, which can move closer or further apart and are used to limit the position of the board material, are located at both ends of the collection box. Two sets of driving units are installed on both sides of the collection box to push the two sets of clamping plates to move relative to each other. Each driving unit includes a detection unit that receives the board material falling through the guide plate and moves it downwards synchronously. As the detection unit moves downwards, it drives the two sets of clamping plates to move closer together.

[0008] Furthermore, the collection box has opening slots on both sides, and the driving unit includes a lead screw with bearings mounted on the side of the clamping plate. The lead screw passes through the opening slot and is movably inserted into the inner wall of the operating box. A guide rail is installed at the bottom of the inner wall of the operating box, and the guide rail is inclined in a direction away from the collection box.

[0009] A slider is slidably mounted on the guide rail, and the detection unit is mounted on the slider and has the same inclination as the guide rail. The slider passes through the clamping plate, and the bottom surface of the clamping plate has a certain gap with the bottom surface of the inner wall of the collection box.

[0010] The detection unit is composed of two sets of opposing sleeved and axially sliding rods. The two sets of rods can be fixed by fasteners. One end of one set of rods is connected to the slider, and one end of the other set of rods is a rounded end. The clamping plate is provided with a first waist groove that matches the diameter of the rod.

[0011] A rack is mounted on the side of the slider, and a first spring is connected between the rack and the bottom of the inner wall of the operating box to initially support the rack. A gear that meshes with the rack is mounted on the bearing on the side of the inner wall of the operating box, and the gear is threadedly connected to the lead screw.

[0012] Furthermore, cylinders are installed near both ends of the guide plate, and limiting plates are installed at the extension and retraction ends of the cylinders.

[0013] Furthermore, the collection box is equipped with a detachable baffle, which is fixedly connected to the collection box by fasteners.

[0014] Furthermore, two sets of protective covers for dust protection of the limiting components are fixedly installed on the operation box, and the protective covers are provided with a second waist groove for vertical movement of the detection part.

[0015] Furthermore, a protrusion is installed on the clamping plate, and a guide rod is movably passed through the protrusion. The clamping plate slides along the straight direction of the guide rod via the protrusion.

[0016] Furthermore, a shearing assembly is installed on the operating box. The shearing assembly includes a bracket installed inside the operating box, two sets of guide posts are installed on the bracket, a shearing table is installed at one end of each set of guide posts, and an mounting plate is movably installed on each set of guide posts.

[0017] A hydraulic cylinder is installed on the bracket, and the telescopic end of the hydraulic cylinder passes through the bracket and connects to the mounting plate. The bottom surface of the mounting plate has a cutter. Second spring members are installed on both sides of the cutter on the shearing table. The second spring members are adapted to contact the mounting plate. A third spring member is connected between the bracket and the cutter.

[0018] Furthermore, the control box has a guide platform for supporting the sheet metal, and a controller is installed on the control box.

[0019] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0020] A shearing machine for calcium sulfate-based antistatic flooring first cuts the board material using a shearing assembly. The cut board material is then guided by a guide plate to fall into a collection box. During the fall, the board material is caught by a detection unit, which moves downwards in sync with the detection unit. The downward movement of the detection unit drives the drive unit to move, pushing the clamping plates at both ends of the collection box closer together. This restricts the position of the board material to the center, ensuring that it slides down along the central axis. This allows the board material to fall into the collection box in an orderly manner, avoiding messy material drop caused by tilting or offset, and reducing subsequent manual labor.

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1 to 5 As shown, this utility model embodiment provides a shearing machine for calcium sulfate-based antistatic flooring, including an operation box 1, a shearing assembly 2, and a limiting assembly 3;

[0033] The limiting component 3 includes a collection box 34 installed in the operation box 1 for receiving the sheared sheet metal, and a guide plate 31 fixedly installed in the operation box 1 to guide the sheared sheet metal to be unloaded. The guide plate 31 is located on one side of the collection box 34, and clamping plates 314 that can move closer or further apart are provided at both ends of the collection box 34. The clamping plates 314 restrict the position of the sheet metal. In addition, two sets of driving units are installed on both sides of the collection box 34 in the operation box 1 to push the two sets of clamping plates 314 to move relative to each other. The driving units include a detection unit 316 that receives the sheet metal falling through the guide plate 31 and moves it down synchronously. When the detection unit 316 moves down, it drives the two sets of clamping plates 314 to move closer to each other.

[0034] When the shearing machine is used to cut the calcium sulfate-based antistatic flooring, the shearing assembly 2 first cuts the board. The cut board is then guided by the guide plate 31 and falls into the collection box 34. During the fall, the board is received by the detection unit 316, which moves down synchronously. The movement of the detection unit 316 drives the drive unit to move, pushing the clamping plates 314 at both ends of the collection box 34 closer together, thereby restricting the position of the board and ensuring that the board falls into the collection box 34 in an orderly manner.

[0035] Specifically, the collection box 34 has opening slots on both sides. The drive unit includes a lead screw 39 with bearings mounted on the side of the clamping plate 314. The lead screw 39 passes through the opening slots and is movably inserted into the inner wall of the operation box 1. At the same time, a guide rail 312 is fixedly installed at the bottom of the inner wall of the operation box 1. The guide rail 312 is inclined away from the collection box 34. A slider 313 is slidably installed on the guide rail 312. The detection unit 316 is fixedly installed on the slider 313 and is perpendicular to the guide rail 312. Meanwhile, the lead screw 39 is inclined and perpendicular to the guide rail 312.

[0036] The slider 313 passes through the clamping plate 314. The bottom surface of the clamping plate 314 has a certain gap with the bottom surface of the inner wall of the collection box 34. The detection part 316 is composed of two sets of opposing sleeved and axially sliding rods. The two sets of rods can be fixed by fasteners. One end of one set of rods is connected to the slider 313, and one end of the other set of rods is a rounded end. At the same time, a first waist groove (not shown in the figure) adapted to the diameter of the rod is opened on the clamping plate 314. The first waist groove is used to provide vertical movement space for the rod.

[0037] Meanwhile, a rack 311 is fixedly installed on the side of the slider 313. The rack 311 is inclined and has the same inclination as the guide rail 312. A first spring 315 is connected between the rack 311 and the bottom of the inner wall of the operating box 1. The first spring 315 is suitable for limiting the initial position of the rack 311. Meanwhile, a gear 310 that meshes with the rack 311 is mounted on the inner wall side of the operating box 1. The gear 310 is threadedly connected to the lead screw 39.

[0038] It should be noted that the smooth end of the rod is suitable for contacting the sheet material falling through the guide plate 31, and moves down synchronously with the sheet material as it falls, so as to drive the slider 313 to move gradually along the inclined direction of the guide rail 312. At this time, the slider 313 drives the gear 310 to rotate, which in turn drives the lead screw 39 to drive the clamping plate 314 to move closer to each other to clamp the falling sheet material. When the smooth end of the rod gradually moves away from the sheet material, that is, when it is no longer pressed down by the sheet material on the smooth end of the rod, it is reset under the action of the first spring 315, and at the same time, it can limit the position of the sheet material falling into the collection box 34.

[0039] After the shearing machine finishes shearing the calcium sulfate-based antistatic flooring sheet, the sheet is guided by the guide plate 31 and falls into the collection box 34. During the fall, the sheet first contacts the smooth end of the rod of the detection unit 316. Since the guide rail 312 is inclined away from the collection box 34, and the inclination of the detection unit 316 is the same as that of the guide rail 312, the gravity of the falling sheet generates a component force in the direction of the guide rail 312, pushing the slider 313 connected to the detection unit 316 to move downward along the inclination direction of the guide rail 312.

[0040] When the slider 313 moves, the rack 311 fixed to its side moves synchronously. Because the rack 311 meshes with the gear 310, the movement of the rack 311 drives the gear 310 to rotate. Since the gear 310 is threadedly connected to the lead screw 39, the rotation of the gear 310 causes the lead screw 39 to move axially. The two ends of the lead screw 39 are mounted on the side of the clamping plate 314 via bearings. The movement of the lead screw 39 causes the clamping plates 314 to move closer together, thereby clamping the falling sheet material and restricting its position so that it can accurately fall into the designated position in the collection box 34. During this process, the two sets of axially sliding rods of the detection unit 316 move within the first groove of the clamping plate 314.

[0041] As the rod gradually contacts the bottom of the inner wall of the first groove, and a certain distance exists between the plate and the collection box 34, the smooth end of the rod gradually moves away from the plate and is no longer subjected to the downward pressure of the plate. At this time, the first spring 315, which is in a state of tension or compression, begins to recover its deformation, pulls the rack 311 and drives the slider 313 to move in the opposite direction along the guide rail 312 to reset.

[0042] During the reset process of slider 313, gear 310 rotates in the opposite direction, and lead screw 39 drives clamping plates 314 to move away from each other and return to the initial position, preparing for the next drop of the plate.

[0043] Specifically, cylinders 32 are fixedly installed on the guide plate 31 near both ends. Limiting plates 33 are fixedly installed on the telescopic ends of the cylinders 32. The two sets of limiting plates 33 are adapted to move closer or further apart under the action of the telescopic ends of the cylinders 32, so as to perform initial pre-positioning of the plate falling on the guide plate 31.

[0044] When cylinder 32 is activated, its telescopic end pushes the limiting plates 33 to move towards each other along the width direction of guide plate 31. Driven by cylinder 32, the two sets of limiting plates 33 gradually approach each other until they adhere to the edges of the material, mechanically confining the material within a preset area in the center of guide plate 31. This pre-positioning process counteracts any positional shift that may occur after the material is sheared, ensuring that the material slides smoothly down the central axis of guide plate 31 to collection box 34, preventing the subsequent detection unit 316 from failing to trigger accurately or the clamping plate 314 from failing to hold due to material misalignment.

[0045] Specifically, a detachable baffle 35 is fixedly installed on the collection box 34. The baffle 35 is fixedly connected to the collection box 34 by fasteners, and the baffle 35 is suitable for being disassembled when a certain amount of board material is accumulated in the collection box 34, so as to facilitate the removal of the board material in the collection box 34.

[0046] As the shearing machine continues to operate, the calcium sulfate-based antistatic flooring sheets in the collection box 34 gradually accumulate to near the height of the baffle 35. The operator can remove the baffle 35 by disassembling the fasteners (such as bolts, clips, etc.). Since the baffle 35 and the collection box 34 are detachably connected, the accumulated sheet material can be directly removed from the side after disassembly. After unloading, the baffle 35 is reinstalled and secured with fasteners, restoring the limiting function of the collection box 34 and allowing it to continue receiving the sheared sheet material.

[0047] Specifically, two sets of protective covers 317 are fixedly installed on the operation box 1. The protective covers 317 are used to shield the limiting component 3 from dust. At the same time, a second waist groove 318 is provided on the protective cover 317 for the detection part 316 to move vertically.

[0048] When the shearing machine is running, two sets of protective covers 317 are fixedly installed on the control box 1 to form a closed shield for the limiting components 3 (such as the collection box 34, drive unit, detection unit 316, etc.), preventing dust and debris generated during the shearing process from entering the mechanical transmission components (such as the lead screw 39, gear 310, rack 311, etc.), avoiding component wear or jamming caused by foreign object intrusion, and extending the service life of the equipment.

[0049] Meanwhile, the second waist groove 318 opened on the protective cover 317 matches the vertical movement trajectory of the detection unit 316, allowing the rod of the detection unit 316 to slide vertically along the waist groove when it falls with the sheet metal, ensuring that the normal linkage of the detection unit 316 is not blocked by the protective cover 317, and the width of the waist groove is adapted to the diameter of the rod.

[0050] Specifically, a protrusion 37 is fixedly installed on the clamping plate 314, and a guide rod 38 is movably passed through the protrusion 37. The guide rod 38 is inclined and perpendicular to the guide rail 312. The clamping plate 314 slides along the straight direction of the guide rod 38 through the protrusion 37.

[0051] When the lead screw 39 of the drive unit moves the clamping plate 314, the protrusion 37 on the clamping plate 314 slides along the linear direction of the guide rod 38. The guide rod 38, as a rigid support fixed within the operating box 1, provides precise linear guidance for the movement of the clamping plate 314, limiting any deviation or wobbling of the clamping plate 314 during movement. The protrusion 37 and the guide rod 38 are connected by a clearance fit or linear bearing, ensuring smooth sliding of the clamping plate 314 while improving the stability of the clamping action through mechanical constraints.

[0052] Specifically, the shearing assembly 2 includes a bracket 21 fixedly installed inside the operation box 1, and two sets of guide posts 23 are fixedly installed on the bracket 21. A shearing table (not shown in the figure) is fixedly installed at one end of the two sets of guide posts 23. An mounting plate 24 is movably installed on the two sets of guide posts 23. A hydraulic cylinder 22 is fixedly installed on the bracket 21. The telescopic end of the hydraulic cylinder 22 passes through the bracket 21 and connects to the mounting plate 24. The bottom surface of the mounting plate 24 has a cutter 25. A second spring member 26 is fixedly installed on the shearing table at both sides of the cutter 25. The second spring member 26 is adapted to contact the mounting plate 24.

[0053] Furthermore, a third spring is connected between the bracket 21 and the cutter 25, which is adapted to cushion the mounting plate 24;

[0054] When the calcium sulfate-based antistatic flooring needs to be sheared, the hydraulic cylinder 22 on the support 21 is activated. Its telescopic end pushes the mounting plate 24 connected to it along the guide post 23 toward the shearing table, and the cutter 25 on the bottom surface of the mounting plate 24 moves closer to the board. During the downward movement of the mounting plate 24, the second spring members 26 located on both sides of the cutter 25 on the shearing table first contact the mounting plate 24 and begin to compress, playing a preliminary buffering role and reducing the impact force at the moment of contact between the cutter 25 and the board.

[0055] As the cutter 25 presses down further to cut into the sheet metal, the third spring connecting the bracket 21 and the cutter 25 also begins to compress, further buffering the pressure of the cutter 25 on the sheet metal. This allows the shearing force to be applied more evenly to the sheet metal, preventing damage due to excessive pressure and reducing the reaction force on the equipment. After the shearing action is completed, the telescopic end of the hydraulic cylinder 22 retracts, and the mounting plate 24, under the tension of the hydraulic cylinder 22 and the elastic reset action of the second and third springs, returns to its original position along the guide post 23, ready for the next shearing task.

[0056] Specifically, the operation box 1 has a guide platform 13, which is used to support the sheet material to be sheared. At the same time, a controller 12 is fixedly installed on the operation box 1, which is used to control the operation of the above-mentioned equipment.

[0057] The guide table 13 serves as a support platform for the sheet metal to be sheared. Its horizontal surface provides a stable placement reference for the sheet metal, ensuring it is in a preset position before shearing. Its surface can be designed with anti-slip textures or fitted with rubber pads to enhance friction during placement and prevent dimensional deviations caused by sheet metal slippage. Operators place the calcium sulfate-based antistatic flooring sheet metal on the guide table 13 and push it manually or with auxiliary devices to the shearing area of ​​the shearing assembly 2.

[0058] Specifically, soft pads are provided at the contact points between the two sets of clamping plates 314 and the sheet material to avoid direct contact between the clamping plates 314 and the sheet material, which could cause damage.

[0059] When the drive unit moves the clamping plates 314 closer together to clamp the calcium sulfate-based antistatic flooring material, the soft pads (such as rubber, silicone, or sponge) at the contact points first adhere to the surface of the material. The soft pads absorb the stress generated by the clamping force through their own elastic deformation, transforming rigid clamping into flexible contact, preventing the metal surface of the clamping plates 314 from directly pressing against the material, which could cause indentations, cracking, or damage to the surface coating. Simultaneously, the high coefficient of friction of the soft pads enhances friction during clamping, preventing the material from slipping during positioning and ensuring clamping stability. When the material falls into the collection box 34, the elastic recovery of the soft pads reduces adhesion to the material when the clamping plates 314 separate, preventing secondary damage caused by pulling.

[0060] In summary: The sheet material to be sheared is placed on the guide platform 13 of the control box 1, and the controller 12 coordinates the linkage of various components. In the shearing assembly 2, the hydraulic cylinder 22 drives the mounting plate 24 to descend along the guide post 23, and the cutter 25 shears the sheet material under the double buffer of the second spring member 26 and the third spring member to avoid impact damage. The sheared sheet material slides down through the guide plate 31, and the cylinders 32 at both ends drive the limiting plate 33 to preposition the sheet material to the center to ensure that it slides down along the central axis.

[0061] When the sheet metal falls, it contacts the smooth end rod of the detection unit 316. Because the guide rail 312 is tilted away from the collection box 34, the component of gravity pushes the slider 313 to slide along the guide rail 312. Through the meshing transmission of the rack 311 and the gear 310, the lead screw 39 drives the clamping plates 314 to move closer together. The soft pads on the clamping plates 314 flexibly hold the sheet metal, allowing it to fall accurately into the collection box 34. After the sheet metal falls into the box, the first spring 315 pulls the slider 313 to reset, and the clamping plates 314 separate. The detachable baffle 35 on the side of the collection box 34 facilitates quick unloading after the sheet metal accumulates, while the protective cover 317, through the second waist groove 318, ensures the normal movement of the detection unit 316 while preventing dust.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
