Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of PVC plastic sheet processing equipment, specifically to a PVC plastic flooring edge trimming machine. Background Technology

[0002] Currently, traditional processing methods for PVC flooring production have significant shortcomings. Existing processes typically involve trimming the edges before slitting the boards. This step-by-step approach is cumbersome and severely impacts production efficiency. The trimming stage requires specialized equipment and procedures to finish the edges of the PVC flooring before transferring it to the slitting equipment for board separation. This not only consumes a significant amount of time but also adds extra steps such as material handling and equipment setup, resulting in a substantial extension of the entire processing cycle.

[0003] Meanwhile, the multi-stage processing mode requires a greater investment of manpower and equipment resources. Each stage requires corresponding operators and processing equipment, which undoubtedly increases the company's production costs. Furthermore, during multiple transfers and processing steps, PVC plastic flooring is prone to quality problems such as surface scratches and dimensional deviations, affecting product quality. Therefore, there is an urgent need to develop a PVC plastic flooring edge trimming machine that can optimize the processing flow, integrate edge trimming and slitting processes, reduce processing steps, and improve processing efficiency and product quality. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a PVC plastic flooring edge trimming machine, which solves the technical problem that the existing process usually adopts the process of first trimming the edges and then cutting into boards. This step-by-step processing method has many procedures and seriously affects the production efficiency.

[0005] According to one aspect, at least one embodiment of this disclosure provides a PVC plastic flooring trimming machine, comprising:

[0006] A processing platform and a gantry frame, wherein the gantry frame is fixed on the processing platform;

[0007] A conveying trimming assembly is disposed on the processing platform;

[0008] A conveyor belt and a slitting and discharge assembly, wherein the conveyor belt is disposed at the bottom of the processing platform and the slitting and discharge assembly is disposed on the processing platform;

[0009] The conveying trimming assembly includes several horizontal openings, which are formed on the surface of the processing platform. A lower roller is rotatably connected to the bottom of the processing platform, and the upper end face of the lower roller is located inside the horizontal openings. An upper roller is connected to the surface of the processing platform via a vertical linear drive.

[0010] As a further technical solution, the upper roller is rotated by a motor, and a pair of trimming blades are provided on the upper roller. The lower end of the trimming blades is located inside the horizontal opening, and an outer ring groove is formed on the surface of the lower roller, with the outer ring groove corresponding to the position of the trimming blades.

[0011] As a further technical solution, the slitting and unloading assembly includes a bottom cover, which is disposed at the bottom of the processing platform. A sliding outlet is provided on the surface of the processing platform, which is connected to the bottom cover. A slitting blade is connected to the gantry frame via a vertical linear drive.

[0012] As a further technical solution, a stabilizing sleeve is provided inside the gantry frame, the stabilizing sleeve is slidably connected to the slitting blade, and a lower pressure roller is rotatably connected to the surface of the processing platform, with the bottom part of the lower pressure roller located inside the sliding outlet.

[0013] As a further technical solution, the bottom of the cover is an inclined structural surface, and the cutting blade is located at the opening edge of the sliding outlet.

[0014] As a further technical solution, a pair of straightening bars are provided on the surface of the processing platform, and waste outlets are opened at both ends of the surface of the processing platform.

[0015] As a further technical solution, both the upper roller and the lower roller have anti-slip structural surfaces with high friction.

[0016] As a further technical solution, the straightening strip has an arc-shaped bending transition structure, and one side surface of the straightening strip is located on the same plane as the inner surface of the cutting blade.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, the conveying and trimming assembly, through the cooperation of upper and lower rollers, simultaneously conveys PVC plastic flooring and uses a trimming blade to cut the edges. This integrates the conveying and trimming processes in traditional step-by-step processing, avoiding material transfer and repeated positioning, and reducing process time. The anti-slip surfaces of the upper and lower rollers enhance the friction with the flooring, preventing slippage and deviation during conveying. Correction strips guide the flooring to precise positioning, ensuring the trimming blade cuts along a preset position, guaranteeing trimming accuracy. This solves the problems of numerous steps and low efficiency in existing processes, improving processing continuity and product edge quality. Attached Figure Description

[0031] like Figures 1-4 As shown, it illustrates a PVC plastic flooring trimming machine according to an embodiment of the present disclosure, comprising:

[0032] The processing platform 1 and the gantry frame 2 are fixed on the processing platform 1;

[0033] The trimming assembly 4 is conveyed and disposed on the processing platform 1.

[0034] The conveyor belt 3 and the slitting and discharge assembly 5 are provided. The conveyor belt 3 is located at the bottom of the processing platform 1, and the slitting and discharge assembly 5 is located on the processing platform 1.

[0035] The conveying trimming assembly 4 includes several horizontal openings 4-1, which are formed on the surface of the processing platform 1. A lower roller 4-2 is rotatably connected to the bottom of the processing platform 1, and the upper end face of the lower roller 4-2 is located inside the horizontal openings 4-1. An upper roller 4-3 is vertically and linearly connected to the surface of the processing platform 1 and is rotated by a motor. A pair of trimming blades 4-4 are provided on the upper roller 4-3, and the lower end of the trimming blades 4-4 is located inside the horizontal openings 4-1. An outer ring groove 4-5 is formed on the surface of the lower roller 4-2, and the outer ring groove 4-5 corresponds to the position of the trimming blades 4-4.

[0036] In some examples, in order to achieve the synchronous processing of floor conveying and trimming, a conveying and trimming assembly 4 is designed. This assembly includes a horizontal opening 4-1 on the surface of the processing platform 1, which provides working space for the upper and lower rollers 4-2 and the trimming knife 4-4. The lower roller 4-2 is rotatably connected to the bottom of the processing platform 1, and its upper end extends from the horizontal opening 4-1 to form a support surface for the floor. The upper roller 4-3 is connected to the surface of the processing platform 1 through a vertical linear drive device composed of its cylinders, and can move up and down to adjust the distance between it and the lower roller 4-2 to adapt to flooring of different thicknesses.

[0037] The upper roller 4-3 is driven by a motor to rotate, and the friction force propels the floorboard forward. Simultaneously, a pair of edge-cutting blades 4-4 on the upper roller 4-3 rotate synchronously with it. The lower ends of the blades extend into the cross opening 4-1 and correspond to the outer ring groove 4-5 on the surface of the lower roller 4-2. As the floorboard passes between the upper and lower rollers 4-2, the edge-cutting blades 4-4 rotate and cut the edges of the floorboard. The arc-shaped structure of the outer ring groove 4-5 precisely matches the cutting trajectory of the edge-cutting blades 4-4, both catching the edge material and guiding it to the outside of the processing platform 1 via the rotation of the lower roller 4-2, achieving automatic edge material collection. The vertical linear drive device can adjust the downward pressure of the upper roller 4-3, ensuring stable clamping of the floorboard while preventing deformation due to excessive pressure, thus improving edge-cutting accuracy and floorboard integrity.

[0038] like Figures 1-4 As shown in the figure, the slitting and unloading assembly 5 proposed in this embodiment includes a bottom cover 5-1, which is disposed at the bottom of the processing platform 1. A sliding outlet 5-2 is opened on the surface of the processing platform 1, and the sliding outlet 5-2 is connected to the bottom cover 5-1. A slitting blade 5-3 is connected to the gantry frame 2 by a vertical linear drive. A stabilizing sleeve 5-4 is disposed inside the gantry frame 2. The stabilizing sleeve 5-4 is slidably connected to the slitting blade 5-3. A lower pressure roller 5-5 is rotatably connected to the surface of the processing platform 1, and the bottom part of the lower pressure roller 5-5 is located inside the sliding outlet 5-2.

[0039] In some examples, to achieve precise slitting and unloading of the trimmed floorboards, a slitting and unloading assembly 5 is designed. This assembly includes a slide outlet 5-2 formed on the surface of the processing platform 1, which connects to the bottom cover 5-1 to form an unloading channel for the floorboards. A vertical linear drive device consisting of cylinders is installed on the gantry frame 2, which is connected to the slitting blade 5-3. This drive device moves the slitting blade 5-3 up and down, laterally slitting the floorboards conveyed above the slide outlet 5-2. A stabilizing sleeve 5-4 is slidably fitted onto the slitting blade 5-3, providing vertical guidance to prevent skewing during slitting and ensuring slitting accuracy.

[0040] The lower pressure roller 5-5 on the surface of processing platform 1 is located inside the slide outlet 5-2 and is driven to rotate by a motor. When the floorboards are trimmed and conveyed to the slide outlet 5-2, the lower pressure roller 5-5 drives the floorboards to continue moving forward through friction. At the same time, when the slitting blade 5-3 cuts downwards, the lower pressure roller 5-5 can press the floorboards firmly to prevent them from tilting or shifting during cutting. The cut floorboard segments fall from the slide outlet 5-2 into the bottom cover 5-1. The inclined inner wall of the bottom cover 5-1 or the built-in conveyor belt 3 can guide the floorboard segments to an external collection device, realizing automated material discharge. This design, through the vertical cutting of the slitting blade 5-3 and the conveying of the lower pressure roller 5-5, ensures that the trimmed floorboards are cut to a preset length and discharged in an orderly manner, improving the automation level and production efficiency of floorboard processing.

[0041] For example, such as Figure 1 As shown, the bottom of the bottom cover 5-1 is an inclined structural surface, and the slitting blade 5-3 is located at the opening edge of the sliding outlet 5-2.

[0042] In some examples, the bottom of the base shroud 5-1 adopts an inclined structural surface, and the slitting blade 5-3 is precisely positioned at the opening edge of the slide outlet 5-2, optimizing the discharge and collection efficiency of the slid floorboards. The inclined surface at the bottom of the base shroud 5-1 typically forms an angle of 15° to 30° with the horizontal plane. When the slid floorboard segments fall from the slide outlet 5-2 into the base shroud 5-1, they can automatically slide towards the outlet of the base shroud 5-1 under the influence of gravity from the inclined surface, avoiding accumulation and blockage. The slitting blade 5-3 is installed directly above the edge of the slide outlet 5-2. When the vertical linear drive device moves the slitting blade 5-3 downward, the blade is precisely aligned with the position of the floorboard to be slid. The edge of the slide outlet 5-2 serves as the reference surface for the downward cut, ensuring that the slitting blade 5-3 cuts into the floorboard vertically, avoiding skewed cuts caused by deviations in the downward cut position.

[0043] For example, such as Figure 3 As shown, a pair of straightening baffles 6 are provided on the surface of the processing platform 1, and waste outlets 7 are provided at both ends of the surface of the processing platform 1.

[0044] In some examples, a pair of straightening baffles 6 on the surface of the processing platform 1 and waste outlets 7 at both ends form a floor guiding and edge material discharge system. The straightening baffles 6 are symmetrically distributed, and their arc-shaped bending transition structure guides the floor along a preset trajectory, avoiding edge trimming errors caused by conveying deviation. For example, when the floor enters the conveying edge trimming assembly 4, the arc-shaped surfaces of the straightening baffles 6 on both sides correct the edge of the floor to the same plane as the inner surface of the edge trimming blade 4-4, ensuring that the edge trimming blade 4-4 accurately cuts the excess parts on both sides of the floor. The waste outlets 7 at both ends of the processing platform 1 correspond to the discharge paths of edge material and finished products, respectively: the edge material cut by the edge trimming blade 4-4 is discharged from one waste outlet 7 as the lower roller 4-2 rotates, while the slit floor segments fall into the bottom cover 5-1 from the other sliding outlet 5-2, realizing the classified discharge of materials.

[0045] For example, such as Figure 1 As shown, the surfaces of the upper roller 4-3 and the lower roller 4-2 are both anti-slip structural surfaces with high friction.

[0046] In some examples, both the upper roller and the lower roller 4-2 feature a high-friction, anti-slip surface. This design enhances the friction between the rollers and the floor, ensuring stable floor conveying and precise edge trimming. The anti-slip surface typically employs knurling, a grid pattern, or a rubber coating; its rough surface increases the contact area, preventing the floor from slipping or shifting between the upper and lower rollers 4-2.

[0047] For example, such as Figure 3 As shown, the straightening strip 6 has an arc-shaped bending transition structure, and one side surface of the straightening strip 6 is located on the same plane as the inner surface of the trimming blade 4-4.

[0048] In some examples, the curved transition structure of the straightening strip 6 is coplanar with the inner surface of the trimming blade 4-4, forming a precise floor positioning and trimming reference. The straight section of the strip and the inner surface of the trimming blade 4-4 are located on the same vertical plane. When the floor is guided to this plane by the straightening strip 6, the trimming blade 4-4 precisely cuts off the excess edge of the floor, ensuring accurate floor width dimensions after trimming.

[0049] In actual use: The PVC plastic flooring is placed on the processing platform 1, and the flooring moves forward along the straightening strips 6 on both sides to be positioned. The upper roller 4-3 and the lower roller 4-2 are started. The upper roller 4-3 is driven vertically and descends to engage with the lower roller 4-2. The upper roller 4-3 is driven by a motor to rotate and conveys the flooring together with the lower roller 4-2 through the anti-slip surface. At the same time, the trimming blade 4-4 on the upper roller 4-3 rotates with the upper roller 4-3 to cut the edges of the flooring on both sides. The straightening strips 6 guide the waste generated by trimming to the waste outlet 7 for discharge. When the flooring is conveyed to the slide outlet 5-2, the slitting blade 5-3 on the gantry frame 2 is driven vertically and descends to slit the flooring laterally. During slitting, the lower pressure roller 5-5 presses the flooring to prevent displacement. The slit flooring segments fall from the slide outlet 5-2 into the bottom cover 5-1 and slide out for collection with the help of the inclined structure of the bottom cover 5-1. Throughout the process, the conveyor belt 3 runs at the bottom of the processing platform 1 to complete the material conveying and realize the simultaneous trimming and slitting.
