Description

Technical Field

[0001] This utility model relates to the technical field of floor cutting equipment, specifically a cutting device for the production of PVC plastic flooring. Background Technology

[0002] PVC flooring is widely used in homes and commercial spaces due to its wear resistance, water resistance, and ease of cleaning. Cutting is a crucial step in its production process, requiring specialized cutting equipment to precisely divide the formed PVC flooring substrate according to the designed dimensions and shapes. This equipment must be adapted to the soft nature of PVC flooring to ensure a stable cutting process, meeting the diverse needs of different scenarios for flooring specifications and supporting the large-scale production of PVC flooring.

[0003] Utility model patent CN223301815U discloses a pressure-resistant plastic floor cutting device. This device includes a vertical guide rail, on which a cutting blade is mounted. A nozzle and a swing assembly are arranged on the side of the vertical guide rail. The swing assembly includes a telescopic sleeve, the upper end of which is fixedly connected to one side of the cutting blade, and the lower end which can slide vertically within the upper end, with a cavity formed therein. This device uses the nozzle to cool the cutting area, effectively preventing the cutting blade from overheating and extending its service life. The water spray function also reduces dust generated during cutting, protecting the environment and the health of operators. By incorporating the swing assembly, the nozzle can swing, expanding the water spray range and improving cooling and dust reduction effects.

[0004] This pressure-resistant plastic flooring cutting device only has a fixed base on the base to secure the flooring, and lacks a cutting groove structure that can move with the cutting blade. When the cutting blade moves laterally to cut the soft PVC plastic flooring, there is no synchronously moving cutting groove on the fixed base for the cutting blade to enter. If the cutting depth exceeds the thickness of the flooring, the cutting blade may directly contact the base surface, causing damage to the base. In view of this, we propose a cutting device for PVC plastic flooring production. Utility Model Content

[0005] The purpose of this invention is to provide a cutting device for the production of PVC plastic flooring, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cutting device for producing PVC plastic flooring includes a workbench with a cutting mechanism.

A first lead screw and a second lead screw are rotatably connected at the top and bottom sides between the two base plates, respectively. The ends of the first lead screw and the second lead screw are synchronously connected through a connecting shaft. The first lead screw passes laterally through the cutting base and is threaded to the cutting base. The second lead screw passes laterally through the movable base and is threaded to the movable base. The first lead screw and the second lead screw rotate synchronously. A rotary motor is coaxially connected to the head end of the first lead screw.

[0007] Preferably, sliding grooves are provided on the inner walls of both the front and rear sides of the movable groove, and protrusions are provided on the end faces of both the front and rear sides of the movable seat, with the two protrusions extending into the two sliding grooves respectively. In this setting, the sliding groove and the protrusion cooperate to guide and limit the movement of the movable seat, preventing it from shifting or shaking, and ensuring that the movable seat and the cutting seat are vertically aligned.

[0008] Preferably, the cutting seat is provided with a first protrusion on both the front and rear end faces, and the two guide rods respectively pass through the two first protrusions axially and are slidably connected to the first protrusions; In this configuration, the first protrusion provides a connection transition between the cutting seat and the guide rod, reducing direct friction between the two and ensuring stable lateral movement of the cutting seat in conjunction with the guide rod.

[0009] Preferably, the top of the cutting seat is provided with a second protrusion, and the first lead screw axially passes through the second protrusion and is threadedly connected to the second protrusion; In this configuration, the second protrusion ensures a stable threaded connection between the first lead screw and the cutting seat, facilitating the conversion of the rotational motion of the first lead screw into the lateral linear motion of the cutting seat.

[0010] Preferably, the movable seat has a cutting groove, the cutting blade of the cutting seat extends into the cutting groove, a fixed sleeve is fixed below the movable seat, and the second lead screw axially passes through the fixed sleeve and is threadedly connected to the fixed sleeve. In this configuration, the cutting groove accommodates the cutting disc, preventing it from contacting the worktable and causing damage and wear; the fixed sleeve ensures a stable connection between the second lead screw and the movable seat, facilitating the second lead screw to drive the movable seat to move laterally.

[0011] Preferably, a first bevel gear is coaxially fixedly connected to the end of the first lead screw, and a second bevel gear is coaxially fixedly connected to the end of the second lead screw. Rotary seats are provided at both ends of the connecting shaft, and the rotating seats are fixedly connected to the seat plate. A pair of connecting bevel gears are fixed on the connecting shaft. The two connecting bevel gears mesh with the first bevel gear and the second bevel gear respectively. The threads of the first lead screw and the second lead screw are in the same direction, and the two connecting bevel gears are located above the first bevel gear and the second bevel gear respectively. In this configuration, the rotating seat supports the connecting shaft to reduce wobbling; the meshing of each bevel gear enables power transmission, and the screws with the same thread direction ensure that the first screw and the second screw rotate synchronously.

[0012] Preferably, the movable slot is provided with a shielding component, which is used to shield the movable slot and prevent PVC plastic flooring from falling into the movable slot.

Example

[0018] Please see Figures 1-6A cutting device for PVC plastic flooring production includes a workbench 100, on which a cutting mechanism 200 is provided. The cutting mechanism 200 includes a pair of base plates 210 respectively fixed to the left and right ends of the workbench 100, a cutting seat 220 disposed between the two base plates 210, and a movable seat 230 disposed directly below the cutting seat 220 and slidably connected to the workbench 100. A movable groove 110 is laterally provided on the top of the workbench 100 for the movable seat 230 to move. The cutting seat 220 is used to install the cutting blade and provides a carrier for the cutting operation. The movable groove 110 provides space for the lateral movement of the movable seat 230 and limits the direction of movement of the movable seat 230.

[0019] like Figure 1 , Figure 4 and Figure 5 As shown, in this utility model, a pair of parallel guide rods 211 are laterally fixed between the two seat plates 210. The two guide rods 211 pass through the cutting seat 220. The front and rear end faces of the cutting seat 220 are provided with first protrusions 221. The two guide rods 211 axially pass through the two first protrusions 221 respectively and are slidably connected with the first protrusions 221, so that the cutting seat 220 can move laterally along the guide rods 211. The guide rods 211, through their cooperation with the first protrusions 221, guide the lateral movement of the cutting seat 220, prevent the cutting seat 220 from deviating during the movement, and ensure that the cutting seat 220 drives the cutting blade to move stably. The first protrusions 221 provide a transition structure for the connection between the cutting seat 220 and the guide rods 211, so that the guide rods 211 can stably pass through the cutting seat 220, while reducing the direct friction between the cutting seat 220 and the guide rods 211.

[0020] like Figure 4 and Figure 5As shown, specifically, a first lead screw 212 and a second lead screw 213 are rotatably connected at the top and bottom sides between the two seat plates 210, respectively. A first bevel gear 2122 is coaxially fixedly connected to the end of the first lead screw 212, and a second bevel gear 2131 is coaxially fixedly connected to the end of the second lead screw 213. Rotary seats are provided at both ends of the connecting shaft 214, and these seats are fixedly connected to the seat plates 210. The rotating seats provide support for the connecting shaft 214, reducing the shaking during rotation. A pair of connecting bevel gears 2141 are fixed on the connecting shaft 214, meshing with the first bevel gear 2122 and the second bevel gear 2131, respectively. The thread direction and size of the first lead screw 212 and the second lead screw 213 are the same. Gear 2141 is located above the first bevel gear 2122 and the second bevel gear 2131 respectively. The first end of the first lead screw 212 is coaxially connected to the rotating motor 2121. The ends of the first lead screw 212 and the second lead screw 213 are synchronously connected through the connecting shaft 214. When the rotating motor 2121 is working, it drives the first lead screw 212 and the second lead screw 213 to rotate synchronously. The connecting shaft 214 serves to connect the first lead screw 212 and the second lead screw 213, ensuring the consistency of their movements. The first bevel gear 2122, the second bevel gear 2131 and the connecting bevel gear 2141 mesh with each other to realize the power transmission between the connecting shaft 214 and the first lead screw 212 and the second lead screw 213, ensuring that the first lead screw 212 and the second lead screw 213 rotate synchronously.

[0021] like Figure 4 and Figure 6 As shown, further, the top of the cutting seat 220 is provided with a second protrusion 222. The first lead screw 212 axially passes through the second protrusion 222 and is threadedly connected to the second protrusion 222. The first lead screw 212 also laterally passes through the cutting seat 220 and is threadedly connected to the cutting seat 220. Through its threaded connection with the cutting seat 220, the first lead screw 212 can convert its rotational motion into the lateral linear motion of the cutting seat 220. A fixed sleeve 233 is fixed below the movable seat 230. The second lead screw 213 axially passes through the fixed sleeve 233 and is threadedly connected to the fixed sleeve 233. The second lead screw 213 then laterally passes through the movable seat 230 and is threadedly connected to the movable seat 230. Through its threaded connection with the movable seat 230, the second lead screw 213 can convert its rotational motion into the lateral linear motion of the movable seat 230.

[0022] like Figure 6As shown, the movable seat 230 is provided with a cutting groove 231, and the cutting blade of the cutting seat 220 extends into the cutting groove 231. The cutting groove 231 can accommodate the cutting blade of the cutting seat 220. When the cutting blade cuts the PVC plastic floor, the bottom of the cutting blade can extend into the cutting groove 231 to avoid the cutting blade directly contacting the worktable 100 and causing damage to the worktable 100. At the same time, it can also reduce the wear of the cutting blade due to contact with the hard worktable 100.

[0023] like Figure 2 , Figure 3 and Figure 6 As shown, it is worth noting that sliding grooves 111 are provided on the inner walls of both the front and rear sides of the movable groove 110, and protrusions 232 are provided on the end faces of both the front and rear sides of the movable seat 230. The two protrusions 232 extend into the two sliding grooves 111 respectively. The sliding grooves 111 and the protrusions 232 cooperate with each other to further guide and limit the movement of the movable seat 230, preventing the movable seat 230 from shifting back and forth or wobbling up and down when moving in the movable groove 110, ensuring that the movable seat 230 and the cutting seat 220 always maintain vertical correspondence, and that the cutting groove 231 can accurately receive the cutting disc.

[0024] It is worth noting that the rotating motor 2121 involved in this utility model is a conventional technology and will not be described in detail here. In this embodiment, the PVC plastic flooring production cutting device is used as follows: First, the PVC plastic flooring to be cut is placed on the workbench 100, with the cutting position between the cutting seat 220 and the movable seat 230. Then, the rotary motor 2121 is started, which drives the first lead screw 212 to rotate. The first lead screw 212 drives the connecting shaft 214 and the second lead screw 213 to rotate synchronously through the first bevel gear 2122, the connecting bevel gear 2141, and the second bevel gear 2131. Next, the first lead screw 212... 2. The cutting seat 220 is driven to move laterally along the guide rod 211 by the threaded engagement with the second protrusion 222. At the same time, the second lead screw 213 drives the movable seat 230 to move laterally along the movable groove 110 by the threaded engagement with the fixed sleeve 233. The cutting seat 220 and the movable seat 230 move synchronously. The cutting blade on the cutting seat 220 cuts the plastic flooring. The bottom of the cutting blade extends into the cutting groove 231 of the movable seat 230. Finally, after the cutting is completed, the rotating motor 2121 is turned off, and the cut PVC plastic flooring can be removed. Example

[0025] To prevent PVC plastic flooring from falling into the movable groove 110, such as Figures 1-4 , Figure 6 and Figure 7As shown, a shielding assembly 240 is provided in the movable slot 110. The shielding assembly 240 is used to shield the movable slot 110. The shielding assembly 240 includes a pair of rotating shafts 241 respectively rotatably connected to the left and right sides of the worktable 100, a drum 242 sleeved on the outside of the rotating shafts 241, and a shielding plate 243 wound on the drum 242. Mounting slots 120 for mounting the rotating shafts 241 are provided on both the left and right end faces of the worktable 100. The mounting slots 120 are connected to the movable slot 110. A coil spring connects the drum 242 and the rotating shafts 241. The end of the shielding plate 243 is fixed to the side end face of the movable seat 230. The shielding assembly 240 can shield the movable slot 110 to prevent debris or other contaminants from the PVC plastic flooring during the cutting process. Small floor tiles fall into the movable groove 110 to prevent the movable groove 110 from being blocked and affecting the movement of the movable seat 230; the rotating shaft 241 provides rotational support for the drum 242, allowing the drum 242 to rotate around the rotating shaft 241; the drum 242 is used to wind the shielding plate 243, making it convenient for the shielding plate 243 to unfold or rewind as the movable seat 230 moves; the mounting groove 120 provides space for the installation of the rotating shaft 241, ensuring that the rotating shaft 241 can be stably fixed on the worktable 100; the coil spring has an elastic restoring function, when the movable seat 230 moves to one side, it can pull one side of the shielding plate 243 to unfold, and the coil spring on the other side drives the drum 242 to rotate and rewind the shielding plate 243, ensuring that the shielding plate 243 can always fit against the top surface of the movable groove 110 for shielding.

[0026] In this embodiment, guide grooves 112 are provided on both the front and rear end faces of the top of the movable groove 110, and limiting edges 2431 are provided on both the front and rear edges of the shielding plate 243. The limiting edges 2431 extend into the guide grooves 112, and the top surface of the shielding plate 243 is flush with the table surface of the workbench 100. The guide grooves 112 and the limiting edges 2431 cooperate with each other to guide the unfolding and rewinding of the shielding plate 243, preventing the shielding plate 243 from shifting forward or backward during movement, and ensuring that the shielding plate 243 can accurately cover the movable groove 110. The top surface of the shielding plate 243 is flush with the table surface of the workbench 100, which can avoid height differences when the plastic floor is placed, and ensure that the plastic floor can stably adhere to the surface of the workbench 100 and the shielding plate 243 without affecting the cutting operation.

[0027] In this embodiment, the PVC plastic flooring production cutting device is used as follows: First, the PVC plastic flooring to be cut is placed on the workbench 100 and the shielding plate 243, so that the position of the plastic flooring to be cut corresponds to the area below the cutting seat 220. Then, the rotating motor 2121 is started, which drives the cutting seat 220 and the movable seat 230 to move laterally synchronously. When the movable seat 230 moves, it pulls one side of the shielding plate 243 to unfold from the drum 242, while the other side of the drum 242 rotates under the action of the coil spring, winding up the excess shielding plate 243. The shielding plate 243 moves within the guide groove 112 via the limiting edge 2431, always maintaining the shielding of the movable groove 110; then, the cutting blade on the cutting seat 220 cuts the plastic flooring, and the debris or small pieces of flooring generated during the cutting process are blocked by the shielding plate 243 and cannot fall into the movable groove 110; finally, after the cutting is completed, the rotating motor 2121 is turned off, the cut plastic flooring is removed, and when the movable seat 230 is reset, the two side rollers 242 retract the shielding plate 243 to the initial state under the action of the coil spring.
