Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a PVC tablecloth cutting machine. Background Art

[0002] PVC tablecloths are highly decorative. Their materials are easy to process, and they can be made into various colors and patterns, suitable for different styles of restaurants and dining places. They have good heat resistance within a certain temperature range and can effectively prevent damage caused by direct contact between hot tableware or sharp objects and the tabletop. Therefore, due to their excellent decoration, practical heat resistance and waterproof functions, as well as simple cleaning methods, PVC tablecloths have become an essential item in modern families and dining places.

[0003] During the production and manufacturing process of PVC tablecloths, it is necessary to cut the extruded PVC tablecloths. During the cutting process, it is necessary to adjust the position of the cutting tool according to the required cutting width of the tablecloth. Currently, most of the cutting tools on cutting machines are fixed, making it difficult to adjust; at the same time, when the thickness of the PVC tablecloth changes, it is also necessary to remove the cutting tool on the original tool clamping mechanism, replace it with a suitable cutting tool, and then cut the PVC tablecloth. Therefore, when adjusting the position of the cutting tool and when it is necessary to replace and disassemble and assemble the cutting tool, the operations are relatively complicated, and the efficiency of disassembly, assembly and adjustment is low, which in turn affects the efficiency of cutting PVC tablecloths with different widths or thicknesses during material change. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a PVC tablecloth cutting machine to solve the problems that the existing cutting mechanism is relatively complicated in operation when adjusting the position of the cutting tool and when it is necessary to replace and disassemble and assemble the cutting tool, and the efficiency of disassembly, assembly and adjustment is low.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: A PVC tablecloth cutting machine includes a cutting table, and a cutting groove is vertically penetrated through the cutting table. It further includes:

[0006] Sliding shafts, external threads are provided on the outer walls of the sliding shafts. One end of the sliding shaft passes through the side wall of the cutting table near the cutting groove, and a threaded hole is provided on the vertical side wall of the cutting table of the cutting groove far from the other end of the sliding shaft. The end of the sliding shaft can pass through the cutting groove and be threadedly connected to the threaded hole of the cutting table;

[0007] A number of cutting units, each cutting unit includes a cutting disc and a number of cutting knives adapted to cut PVC tablecloths of different thicknesses. The number of cutting knives is circumferentially arranged around the cutting disc. An installation hole slidably connected to the outer wall of the sliding shaft is provided in the middle of the cutting disc, and a number of detachable locking units are provided between the cutting disc and the sliding shaft.

[0008] The technical principle of the present utility model is as follows: When using a PVC tablecloth cutting machine to cut a PVC tablecloth, first select an appropriate number of cutting units to be coaxially inserted onto the sliding shaft according to the specifications of the PVC tablecloth to be cut and the required cutting width of the PVC tablecloth to be cut, so that the PVC tablecloth can be cut by multiple cutting knives simultaneously to form multiple pieces of PVC tablecloth, and the cutting of the large-width PVC tablecloth can be completed at one time.

[0009] When adjusting the number of cutting units, turn the sliding shaft so that the end of the sliding shaft disengages from the threaded hole, and then the number of cutting units on the sliding shaft can be adjusted. The adjustment of the cutting units is convenient; after completing the adjustment of the number of cutting units on the sliding shaft, just turn the end of the sliding shaft and install it onto the threaded hole again. The disassembly and assembly control of the sliding shaft is also very convenient and labor-saving.

[0010] Since there are several cutting knives adapted to the cutting of PVC tablecloths of different thicknesses on the cutting disc, when different cutting knives are needed to cut PVC tablecloths of different thicknesses, by turning the sliding shaft, the sliding shaft drives several cutting discs to rotate synchronously, so that different cutting knives face the PVC tablecloth, and the switching of the cutting knives can be quickly realized.

[0011] Furthermore, a part of the cutting knife can be located above the cutting groove, and the vertical plane where the cutting edge of the cutting knife is located is perpendicular to the axis of the cutting disc.

[0012] Through the above settings, the cutting edge of the cutting knife can accurately expose at the cutting groove, which is also convenient for accurately cutting the PVC tablecloth on the cutting table.

[0013] Furthermore, a slot for the side of the cutting knife away from the cutting edge to be inserted is provided on the circumferential surface of the cutting disc. The cutting disc is axially penetrated with a first mounting hole, and the cutting knife is penetrated with a second mounting hole that can coincide with the first mounting hole. A fixing bolt and a locking nut cooperating with the fixing bolt are detachably installed at the first mounting hole and the second mounting hole.

[0014] Through the above settings, when it is necessary to replace the cutting knife on the cutting disc, the fixing bolt and the locking nut between the single cutting knife and the cutting disc can also be disassembled to replace the single cutting knife on the cutting disc, and the tool change can also be realized. The conversion of the cutting knife is convenient, and the adaptability of the entire PVC tablecloth cutting machine is stronger.

[0015] Furthermore, it also includes a guiding roller for tensioning and guiding the PVC tablecloth. The guiding roller is located on both sides of the cutting table, and the axis of the guiding roller is parallel to the axis of the sliding shaft, and the roller surface of the guiding roller is lower than the upper surface of the cutting table.

[0016] With the above settings, the PVC tablecloth to be cut is passed through the guide rollers on both sides in sequence. The guide rollers cooperate with the feeding and winding mechanisms connected to the PVC tablecloth, and the PVC tablecloth to be cut is tensioned on the upper surface of the cutting table, so that the PVC tablecloth can be in full contact with the cutting knife.

[0017] Furthermore, the detachable locking unit includes:

[0018] A number of locking bolts, which are arranged radially along the cutting disc, and the locking bolts are threadedly connected to the cutting disc;

[0019] An anti-slip layer, a number of grooves for fixing and installing the anti-slip layer are arranged radially on the circumferential surface of the sliding shaft, and one end of the locking bolt close to the cutting disc can abut against the anti-slip layer.

[0020] With the above settings, when it is necessary to adjust the positions of the cutting discs on the sliding shaft, only need to loosen the locking bolts on the cutting discs, and the locking bolts no longer abut tightly against the anti-slip layer. At this time, the cutting discs can slide axially along the sliding shaft. After sliding to the corresponding positions, screw the locking bolts again so that the locking bolts abut tightly against the anti-slip layer of the grooves again. The position adjustment of the cutting discs is convenient and labor-saving.

[0021] Furthermore, there is exactly one locking bolt between two adjacent cutting knives.

[0022] With the above settings, the locking bolts can be arranged more evenly on the cutting disc, and can also accurately provide a stable radial supporting force for the cutting knife.

[0023] Furthermore, a handle ring is coaxially and fixedly installed at one end of the sliding shaft away from the threaded hole, and a positioning nut is provided between the handle ring and the side wall of the cutting table. The positioning nut is threadedly connected to the sliding shaft.

[0024] With the above settings, when screwing the sliding shaft, the human hand can hold the handle ring to apply force, making the screwing of the sliding shaft simpler and labor-saving; at the same time, the positioning nut can abut against and lock the rotating sliding shaft to prevent the sliding shaft from rotating under the horizontal pulling force of the PVC tablecloth, thereby improving the position accuracy of the cutting knife during cutting and enabling continuous cutting processing.
