Description

Technical Field

[0001] The present invention relates to a porcelain plate cutting machine track composed of multiple short rails and suction cups, which can not only meet the requirements of one-time scribing (marking) and cutting of plates with different specifications (lengths), but also ensure the quality of scribing (marking) and cutting, belonging to the field of plate cutting machine manufacturing. Background Art

[0002] EP3415473B1, titled "Sheet Cutting System", the cutting system includes: a scribing slider, a longitudinal guide, the longitudinal guide including a pair of opposite surfaces, the lower surface of the pair of opposite surfaces being adapted to face the slab being processed, and the longitudinal guide including opposite upper surfaces, the upper surfaces being equipped with a pair of tracks that are parallel to each other and adapted to be slidably coupled to the scribing slider (simultaneously); at least one suction cup, which is coupled (e.g., rigidly engaged) to the lower surface of the longitudinal guide, preferably aligned with the lower (and upper) surface of the longitudinal guide itself in a plan view, the suction cup being adapted to selectively adhere to the surface of the slab and defining a substantially flat contact surface for the longitudinal guide on the surface of the slab, wherein the tracks are arranged on opposite sides with respect to the intermediate plane of the suction cup itself (parallel to the longitudinal axis of the longitudinal guide), and for example, due to this solution, a better distribution of the mechanical stress applied to the cutting system is achieved in order to eliminate or at least attenuate the change in orientation of the longitudinal guide, which may cause irregular scribing or damage the surface of the slab. In particular, during the travel of the slab along the longitudinal guide, when a longitudinal scribing cut is formed on the slab, the angular momentum released on the longitudinal guide due to the pressure applied to the scribing slider. In an embodiment of the present invention, the tracks are parallel to the intermediate plane of the suction cup, e.g., parallel to the longitudinal axis of the longitudinal guide. In this way, an even better distribution of the mechanical stress applied to the cutting system I is achieved. The clamping member includes a lever that can be operated to switch the suction cup from a clamping state of the plate to a stationary state where the suction cup releases the plate; in an embodiment of the present invention, the rod of the clamping member can rotate from an engagement position where the suction cup is in the clamping state to a release position where the suction cup is in the stationary state; thus, the lever has an extremely limited obstruction along the vertical direction (perpendicular to the lower surface) of the cutting system in the engagement and release positions. In practice, due to this solution, when the suction cup is in the clamping state and when the suction cup is in the stationary state, the lever allows the slider to slide, which is undoubtedly beneficial for the cutting personnel. In an embodiment of the present invention, the scribing slider includes at least two rollers, each roller being adapted to rotate on one of a pair of tracks, a scribing member adapted to scribe the slab, and a slider body that is coupled to the rollers and the scribing member. When the scribing slider is connected to the track by the rollers, the slider body defines an opening that is adapted to receive the rod of the clamping member in the engagement or release position during the sliding of the scribing slider along the longitudinal guide. In this way, the possibility of freely moving the scribing slider along the longitudinal guide is achieved. The problems it has are: 1. Limited by the length of the longitudinal guide rail, this sheet cutting system cannot be used for one-time cutting of sheets beyond the established longitudinal guide rail length.For example, when the length of the longitudinal guide rail is less than the length of the plate to be cut, it is impossible to complete the cutting of the plate length in one go, and it is necessary to splice the cutting marks and cut them twice or multiple times. However, the splicing of the cutting marks for the second or multiple times simply cannot ensure the consistency of the separation surface of the cut plate, resulting in the inability to achieve seamless splicing between the plates. If a longer guide rail is replaced, the user needs to purchase longitudinal guide rails of different lengths (because the lengths of the plates are different), which not only increases the user's usage cost but also is inconvenient to carry, thus failing to meet the needs of consumers. 2. When the suction cup is attached to the lower surface of the longitudinal guide rail, it means that the lower surface of the longitudinal guide rail is lifted by the suction cup and cannot be fitted to the plate surface. At this time, when the scribing wheel cuts the plate forcefully downward, due to the influence of the downward pressure of the scribing slider handle, the guide rail produces different degrees of downward deformation according to the distance from the suction cup. This different degree of downward deformation directly makes the scribing cutting force of the plate inconsistent, resulting in the phenomenon of broken lines and uneven cutting on the cut plate surface, and causing the cut surface of the plate to be uneven or broken easily when the plate is broken after scribing (marking). 3. The rollers in the scribing (marking) slider roll along the track either horizontally or vertically in an open manner along the track surface, rather than rolling along the track surface with a clamp. Therefore, when the roller jumps during forward rolling, it will cause the scribing (marking) wheel to jump accordingly, and the jumping of the scribing (marking) wheel will inevitably cause the phenomenon of missed cutting on the cutting surface of the plate, thereby affecting the cutting quality, the quality of the cut surface of the plate, and the yield of the cut surface of the plate. EP3415473B1, titled "Plate Cutting System", the cutting system includes: a scribing slider, a longitudinal guide member, the longitudinal guide member includes a pair of opposite surfaces, the lower surface of the pair of opposite surfaces is adapted to face the slab being processed, and the longitudinal guide member includes opposite upper surfaces, the upper surfaces are provided with a pair of tracks that are parallel to each other and are adapted to be slidably coupled to the scribing slider (simultaneously); at least one suction cup, which is coupled (e.g., rigidly engaged) to the lower surface of the longitudinal guide member, preferably aligned with the lower (and upper) surface of the longitudinal guide member itself in a plan view, the suction cup is adapted to selectively adhere to the surface of the slab and defines a substantially flat contact surface for the longitudinal guide member on the surface of the slab, wherein the tracks are arranged on opposite sides with respect to the intermediate plane of the suction cup itself (parallel to the longitudinal axis of the longitudinal guide member), and for example, due to this solution, a better distribution of the mechanical stress applied to the cutting system is achieved, so as to eliminate or at least weaken the change in the orientation of the longitudinal guide member, which may cause irregular scribing or damage the surface of the slab. In particular, during the movement of the slab along the longitudinal guide member, when a longitudinal scribing incision is formed on the slab, the angular momentum released on the longitudinal guide member due to the pressure applied to the scribing slider. In an embodiment of the present invention, the tracks are parallel to the intermediate plane of the suction cup, for example, parallel to the longitudinal axis of the longitudinal guide member. In this way, an even better distribution of the mechanical stress applied to the cutting system I is achieved.The clamping member includes a lever that can be operated to switch the suction cup from a plate-clamping state to a stationary state where the suction cup releases the plate; in an embodiment of the present invention, the rod of the clamping member can rotate from an engagement position where the suction cup is in a clamping state to a release position where the suction cup is in a stationary state; thus, the lever has extremely limited obstruction along the vertical direction (perpendicular to the lower surface) of the cutting system at the engagement and release positions. In practice, due to this solution, when the suction cup is in the clamping state and when the suction cup is in the stationary state, the lever allows the slider to slide, which is undoubtedly beneficial for the cutting operator. In an embodiment of the present invention, the scribing slider includes at least two rollers, each roller being adapted to rotate on one of a pair of tracks, a scribing member being adapted to scribe the slab, and a slider body that is coupled to the rollers and the scribing member. When the scribing slider is connected to the track by the rollers, the slider body defines an opening that is adapted to receive the rod of the clamping member at the engagement or release position during the sliding of the scribing slider along the longitudinal guide. In this way, the possibility of freely moving the scribing slider along the longitudinal guide is achieved. The existing problems are as follows: 1. Limited by the length of the longitudinal guide rail, this sheet cutting system cannot be used for one-time cutting of sheets that exceed the established length of the longitudinal guide rail. For example, when the length of the longitudinal guide rail is less than the length of the sheet to be cut, it is impossible to complete the cutting of the sheet length in one go, and it is necessary to splice the cutting marks, and cut the sheet twice or multiple times. However, the secondary or multiple splicing cutting marks simply cannot ensure the consistency of the separation surface of the cut sheet, resulting in the inability to achieve seamless splicing between sheets. If a longer guide rail is replaced, the user needs to purchase longitudinal guide rails of different lengths (because the sheet lengths are different), which not only increases the user's usage cost but also is not convenient to carry, thus unable to meet the needs of consumers. 2. When the suction cup is attached to the lower surface of the longitudinal guide rail, it means that the lower surface of the longitudinal guide rail is raised by the suction cup and cannot fit with the sheet surface. At this time, when the scribing wheel is forcefully scribing and cutting the sheet downward, under the influence of the downward pressure of the scribing slider handle, the guide rail will have different degrees of downward deformation according to the distance from the suction cup. This different degree of downward deformation directly makes the scribing cutting force of the sheet inconsistent, resulting in the phenomenon of broken lines and uneven cutting on the cut sheet surface, and causing the cut surface of the sheet to be uneven or fractured easily when the sheet is broken after scribing (marking). 3. The rollers in the scribing (marking) slider roll along the track surface in an open manner, whether horizontally or vertically along the track, rather than rolling along the track surface with a hoop. Therefore, when the roller jumps during the forward rolling and sliding, the scribing (marking) wheel will jump accordingly, and the jumping of the scribing (marking) wheel will inevitably cause the phenomenon of missed cutting on the cutting surface of the sheet, thereby affecting the cutting quality, the quality of the cut surface of the sheet, and the yield rate of the cut surface of the sheet. Summary of the Invention

[0003] Design purpose: To avoid the deficiencies in the background technology, a porcelain plate cutting machine track composed of multiple short rails and suction cups is designed, which can not only meet the requirements of one-time scribing (marking) and cutting of plates with different specifications (lengths), but also ensure the quality of scribing (marking) and cutting.

[0004] Design solution: To achieve the above design objectives, in terms of structural design, the present invention is as follows: 1. The longitudinal guide rail is composed of multiple short rail bodies with the same or different lengths that are butt-inserted to the front and rear surfaces of the suction cup. The design of the side-by-side relative insertion of multiple short rail bodies is one of the technical features of the present invention. The purpose of this design is as follows: In the background technology EP3415473B1, the length of the longitudinal guide rail is predetermined by its design, that is, the length of the longitudinal guide rail is a fixed value, and its length cannot be changed during use. When the length of the plate to be scribed (scored) and cut is greater than the length of the longitudinal guide rail, it cannot be scribed (scored) and cut in one go, and it is necessary to splice the scribing (scoring) and cutting, so it is impossible to ensure the consistency of the separation surface of the plate to be scribed (scored) and cut, resulting in the inability to achieve seamless splicing between plates. To solve this problem, the present invention designs the longitudinal guide rail into a segmented plug-in structure composed of multiple short rails, and the lengths of the short rails can be of various specifications. Theoretically, the length of the guide rail can be infinitely extended through longitudinal plug-in. In practice, the longitudinal guide rail of the required length can be plugged according to the length of the plate to be cut, so as to ensure that the cutting wheel in the cutting device can complete the scribing (scoring) and cutting of the plate along the longitudinal guide rail in one go, ensuring the consistency of the cutting section of the plate to be cut, and thus solving the technical problems that could not be solved in the background technology. 2. The design that the upper top and lower bottom of the through grooves on both sides of the short rail body are inlaid with optical axes relatively to form a longitudinal sliding track is the second technical feature of the present invention. The purpose of this design is as follows: In the background technology EP3415473B1, for the disclosed rollers, whether they are horizontally installed or vertically installed, the concave arc surface of the roller always rolls on the track surface. When there are impurities on the track surface, the roller will inevitably jump on the track surface, and this jump will cause the driven scribing wheel (cutting wheel) to jump, resulting in the phenomenon of missed cutting of the cutting line of the plate. This missed cutting phenomenon will cause the enamel on the cutting section of the plate to be chipped locally after the cutting is completed, thereby affecting the cutting quality and the use quality of the plate. To solve this problem, the present invention changes the roller to a U-shaped groove bearing. Since the cooperation precision and rolling resistance of the U-shaped groove bearing are much smaller than those of the roller, when moving along the track, it not only has small resistance but also will not deviate. Secondly, the present invention adopts a track composed of double guide rails, so that the double guide rails form a hoop fit with the U-shaped groove bearing surface. In this way, when there are impurities on the track surface, the U-shaped groove bearing cannot pass through, and it can only pass through after the impurities are removed. This avoids the occurrence of the missed cutting phenomenon of the cutting wheel, and thus will not occur the phenomenon of local chipping of the enamel on the cutting section of the plate, ensuring the quality of the cutting section of the plate. 3. The design that the lower part of the suction cup is separated from the longitudinal guide rail is the third technical feature of the present invention. The purpose of this design is as follows: In EP3415473B1, the disclosed suction cup is attached to the lower surface of the longitudinal guide rail, which means that the lower surface of the longitudinal guide rail is raised by the suction cup and cannot fit with the plate surface. To maintain balance, EP3415473B1 uses the method of adding gaskets to solve this problem.However, the gasket can only provide local support and cannot fully support the longitudinal guide rail. Therefore, when the scribing (marking) wheel cuts the plate downward with force, the guide rail between the gaskets will be deformed downward to varying degrees under the influence of the downward pressure of the scribing (marking) slider handle according to the distance between the gaskets. This deformation directly causes the inconsistent scribing (marking) cutting force on the plate, resulting in inconsistent cutting force of the scribing (marking) wheel on the plate surface, and leading to the coexistence of the phenomenon that the cut line of the plate is either cut through or not cut through. This coexistence phenomenon inevitably causes the cut surface of the plate to be uneven or broken when it breaks behind the scribing wheel. To solve this problem, the present invention designs a clearance position on the short rail body to clear the suction cup body and the rubber base. That is to say, the lower surface of the opposite side of the short rail body and the suction cup body and the rubber base are not in contact. The rubber base and the lower surface of the short rail body are on the same plane. When the suction cup sucks the plate surface, the suction force generated by the suction cup forces the lower surface of the short rail to be in close contact with the plate. Therefore, when the scribing (marking) wheel cuts the plate downward with force, the scribing (marking) cutting force received by the plate is consistent, ensuring that the cut line of the plate will not have the phenomenon of broken line and uneven cutting, and ensuring that the cut surface of the plate will not be uneven or broken when it breaks after scribing (marking).

[0005] Technical solution: A porcelain plate cutting machine track composed of multiple short rails and suction cups, including a longitudinal guide rail and a suction cup. The longitudinal guide rail is formed by butt-inserting multiple short rail bodies with the same or different lengths with the front and rear surfaces of the suction cup, and the side surfaces of the multiple short rail bodies are inserted relatively. The optical axes are respectively embedded in the upper and lower bottoms of the through grooves on both sides of the short rail body to form a longitudinal sliding track relatively.

[0006] Compared with the background technology, the present invention has the following advantages: First, the realization of the longitudinal insertion and extension structure of multiple short rail bodies with multiple suction cups not only achieves the purpose of freely connecting and extending the track length according to the length of the plate to be cut, but also ensures the purpose of firmly adsorbing the guide rail on the plate surface by the suction cup. Furthermore, it realizes that no matter how long the plate is, it can be scribed (marked) and cut through the present invention at one time, and ensures the consistency of the cut surface of the plate to be cut; Second, the present invention designs multiple short rails into a hoop-shaped rail, realizing the hoop of the upper and lower short rail surfaces on the U-shaped groove shaft surface in the cutting device, and solving the defects existing in the technology of EP3415473B1; Third, the design of separating the lower part of the suction cup of the present invention from the longitudinal guide rail eliminates the defects brought by using gaskets to support the height distance between the lower surface of the track and the suction cup in the technology of EP3415473B1, making the scribing cutting force received by the plate surface consistent, not only ensuring that the cut line of the plate will not have the phenomenon of broken line and uneven cutting, but also ensuring that the cut surface of the plate will not be uneven, chipped or broken when it breaks after scribing (marking).

[0016] Example 1: Refer to the appendix Figure 1 and 9 . A track for a porcelain plate cutting machine composed of multiple short rails and suction cups, including a longitudinal guide rail, a suction cup, and a cutting device. The longitudinal guide rail is formed by butt-joint plugging of multiple short rail bodies 1 with the same or different lengths to the front and back of the suction cup 2, and the sides of the multiple short rail bodies 1 are plugged relative to each other. The optical axes 1-1 are respectively embedded in the upper and lower bottoms of the through grooves on both sides of the short rail body to form a longitudinal sliding track.

[0017] Refer to the appendix Figure 1 . The guide rail 1 is designed with a step 1-4 to cooperate with the upper slot 6-5-1 on the suction cup, the 1-1 on the guide rail cooperates with the guide rail 1-2, and the guide rail 1 is designed with clearance positions 1-3, and 1-3 is used to provide clearance for the suction cup main body 6-5 and the rubber base 6-7. After the cooperation is completed, the guide rail 1 and the connecting connecting piece 6-2 are spliced by tightening the plum blossom nut 6-1.

[0018] Refer to the appendix Figure 1-6 . The short rail body 1 is butt-joint plugged and cooperated with the front and back of the suction cup 2, and the sides of the short rail body 1 are plugged and connected through the optical axis 1-1.

[0019] On both sides of the short rail body 1 are through grooves 1-6. Through optical axis card slots 1-2 are respectively opened on the opposite end faces of the upper top and the lower bottom of the through groove. Optical axes 1-1 are respectively embedded in the through optical axis card slots 1-2. The optical axes connect multiple short rail bodies 1 in an inserted manner to form a hoop-type U-groove bearing sliding track. The relatively exposed surfaces of the hoop-type U-groove bearing sliding guide rail are in sliding fit with the U-groove bearing in the cutting device.

[0020] The through grooves on the butting surfaces of both sides of the short rail body 1 are butted seamlessly and out of alignment. See Figure 1 .

[0021] The end face of the short rail body 1 is a profile forming structure. On both sides are through grooves 1-6. In the middle is a shaped support composed of an upper longitudinally open cavity and a lower longitudinally through cavity. The two walls of the upper longitudinally open cavity of the shaped support form reverse top locking grooves 1-5.

[0022] After the through grooves 1-6 on both sides of the multiple short rail bodies 1 are butted through the optical axes 1-1, the suction cup 2 is clamped in the middle. The suction cup 2 is provided with an inverted T-shaped rail connecting member 6-2. T-shaped slots 6-2-1 are opened on both sides of the vertical rod of the inverted T-shaped rail connecting member 6-2. The T-shaped slots 6-2-1 form a plug-in fit with the through slots of the suction cup main body 6-5. The plum blossom nut 6-1 is screwed down to tightly press against the bottom of the reverse top locking groove 1-5 to fix the T-shaped rail connecting member 6-2 and the reverse top locking groove 1-5 into one body.

[0023] An avoidance position 1-3 is designed on the short rail body 1. The avoidance position 1-3 is used to avoid the suction cup main body 6-5 and the rubber base 6-7; a step 1-4 is designed on the upper surface of the rail body 1 to be in plug-in fit with the upper card slot 6-5-1 of the suction cup 2.

[0024] Characteristics of the short guide rail body structure: The short guide rail body is composed of an aluminum profile 1 and four optical axes 1-1 to form a relatively hoop-shaped track up and down. As Figure 5-7 shown, the optical axes 1-1 are distributed out of alignment as Figure 7 shown. The out-of-alignment distribution is for, on the one hand, better splicing of the guide rails, and on the other hand, when the slider slides on the guide rail, the intersection and misalignment are beneficial to the smooth sliding of the slider on the guide rail.

[0025] A "T" - shaped slot 1-5 is designed on the short guide rail body 1. The "T" - shaped slot 1-5 is in clearance-free fit with the "T" - shaped slot 6-2-1 of the rail connecting member 6-2 to ensure no misalignment connection between the guide rails. Refer to the appendix Figure 7The suction cup 2 is composed of a plum blossom nut 6-1, a guide rail connecting piece 6-2, a pin shaft 6-3, a wrench 6-4, a suction cup main body 6-5, a spring 6-6, and a rubber base 6-7; the bottom of the suction cup main body 6-5 is disc-shaped, the butt joint surface of the suction cup main body 6-5 and the short rail body 1 is arc-shaped, and grooves 6-5-2 and clamping grooves 6-5-1 are successively formed on the arc-shaped surface from bottom to top. There is an arc-shaped boss 6-5-3 at the bottom of the suction cup main body 6-5 on the non-butt joint surface with the short rail body 1, and the bottom of the suction cup main body on the non-butt joint surface with the suction cup is a plane 6-5-4, and a channel 6-5-5 is formed between the plane 6-5-4 and the arc-shaped boss 6-5-3.

[0026] The guide rail connecting piece 6-2 is designed with a T-shaped groove 6-2-1 that cooperates with the T-shaped groove of the suction cup main body 6-5, and a threaded hole 6-2-2 that is connected to the plum blossom nut 6-1. The rubber base 6-7 is connected to the spring 6-6 through 6-3-3 on the guide rail connection and the suction cup main body 6-5, and is fixed to the suction cup main body through the suction cup wrench 6-4 and the cylindrical pin 6-3.

[0027] It should be understood that: Although the above embodiments have made a relatively detailed written description of the design concept of the present invention, these written descriptions are only simple written descriptions of the design concept of the present invention, rather than limitations on the design concept of the present invention. Any combination, addition, or modification that does not exceed the design concept of the present invention falls within the protection scope of the present invention.
