Description

Technical Field

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

[0002] EP3415473B1, titled "Sheet Cutting System", the cutting system includes: a scribing slider, a longitudinal guide member, the longitudinal guide member 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 member including opposite upper surfaces, the upper surfaces being provided 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 member, preferably aligned with the lower (and upper) surface of the longitudinal guide member 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 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 in order to eliminate or at least attenuate the change in orientation of the longitudinal guide member, which may cause irregular scribing or damage the surface of the slab. In particular, during the travel of the slab along the longitudinal guide member, when a longitudinal scribing cut is formed on the slab, the angular momentum released on the longitudinal guide member due to the pressure applied to the scribing slider. In one 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, the lever being operable to switch the suction cup from a clamping state of the plate to a stationary state where the suction cup releases the plate; in one embodiment of the present invention, the rod of the clamping member can rotate from an engagement position applying the clamping state of the suction cup to a release position applying the stationary state of the suction cup; 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, the lever allows the slider to slide when the suction cup is in the clamping state and when the suction cup is in the stationary state, which is undoubtedly beneficial for the cutting personnel. In one 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, the slider body being coupled to the rollers and the scribing member. When the scribing slider is connected to the track through the rollers, the slider body defines an opening, the opening being 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 member. In this way, the possibility of freely moving the scribing slider along the longitudinal guide member is achieved. The existing problem is: 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 at one time, and it is necessary to splice the cutting marks and cut it twice or more times. However, the splicing cutting marks for the second or multiple times simply cannot guarantee the consistency of the separation surface of the cut plate, resulting in the inability to achieve seamless splicing between the plates. If a long guide rail is replaced, the user needs to purchase longitudinal guide rails of different lengths (because the plate lengths are different), which not only increases the user's usage cost but also is inconvenient 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 lifted by the suction cup and cannot fit with the plate surface. At this time, when the scribing wheel forces down to scribe the plate, 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 phenomenon of uneven or broken cut surfaces when the plate is broken after scribing (marking). 3. The rollers in the scribing (marking) slider roll along the track either horizontally or vertically, and they all roll along the open track surface rather than the clamped track surface. Therefore, when the rollers jump 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 rate of the cut surface of the plate. Summary of the Invention

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

[0004] Design solution: To achieve the above design objectives, in terms of structural design, the present invention has the following features: 1. The longitudinal guide rail is composed of multiple short rail bodies with the same or different lengths, which are butt-inserted into 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 art EP3415473B1, the length of the longitudinal guide rail is determined in advance 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 splicing scribing (scoring) and cutting is required. In this way, 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 together according to the length of the plate to be cut, thereby ensuring 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 art. 2. The design that the upper and lower bottoms of the through grooves on both sides of the short rail body are embedded with optical axes opposite to each other 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 art 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 scribing wheel (cutting wheel) driven by it to jump, resulting in the phenomenon of missing cuts on the cutting line of the plate. This missing cut phenomenon will cause the enamel on the cutting section of the plate to crack locally after cutting, thereby affecting the cutting quality and the quality of the plate in use. To solve this problem, the present invention replaces the roller with a U-shaped groove bearing. Since the matching accuracy 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 uses 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 missing cut phenomenon of the cutting wheel, and thus will not occur the phenomenon of local cracking 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 partial 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 according to the distance between the gaskets under the influence of the downward pressure of the scribing (marking) slider handle. This deformation directly causes inconsistent scribing (marking) cutting forces on the plate surface, resulting in inconsistent cutting forces on the plate surface by the scribing (marking) wheel, leading to the coexistence of the cut-through and non-cut-through phenomena of the cutting line on the plate. This coexistence phenomenon inevitably causes the cut surface of the plate to be uneven or fractured when it breaks behind the scribing wheel. To solve this problem, the present invention designs a clearance position on the short rail body, which is used 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 cutting line of the plate will not have the phenomena of broken line and uneven cutting, and ensuring that the cut surface of the plate will not be uneven or fractured when it breaks after scribing (marking). 4. Changing the vertical lower handle in EP3415473B1 to a lever downward pressure design is the fourth technical feature of the present invention. The purpose of this design is as follows: The handle in EP3415473B1 uses vertical downward pressure to force the scribing wheel to complete the scribing (marking) cutting of the enamel on the plate surface, which is not labor-saving and it is very difficult to control the magnitude of the downward pressure. However, the present invention designs it with a lever downward pressure structure, which not only makes it easy to master the downward pressure but also is very labor-saving. For example, under the same scribing (marking) cutting conditions of the plate, the present invention only uses less than one-tenth of the force in the background technology EP3415473B1.

[0005] Technical solution: A porcelain plate cutting machine composed of multiple short rails and a suction cup, including a longitudinal guide rail, a suction cup, and a cutting device. The longitudinal guide rail is formed by butt-inserting multiple short rail bodies with the same or different lengths with the front and rear sides of the suction cup, and the side surfaces of the multiple short rail bodies are inserted opposite to each other. 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. In the cutting device, the U-shaped groove bearing is clamped by the longitudinal sliding track to form a seamless sliding fit.

[0006] Compared with the background art, the present invention has the following advantages: First, the longitudinal connection and extension structure of multiple short rail bodies with multiple suction cups is realized. This 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 that the suction cups firmly adsorb the guide rail on the plate surface. As a result, no matter how long the plate is, it can be scribed (marked) and cut in one pass by the present invention, and the consistency of the cross-section of the plate to be cut is ensured. Second, the present invention designs multiple short rails into a hoop-shaped track, realizing the hoop of the upper and lower short rail surfaces on the U-shaped groove shaft surface of 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 from the longitudinal guide rail in the present invention 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 and cutting force received by the plate surface consistent. This not only ensures that the cutting line of the plate will not break or be unevenly cut, but also ensures that the cross-section of the plate will not be uneven, chipped or broken when it is broken after scribing (marking).

Specific implementation method

[0022] Example 1: Refer to the appendix Figure 1 and 15 . A porcelain plate cutting machine composed of multiple short rails and suction cups includes 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 with the front and back of the suction cup 2. The side surfaces of the multiple short rail bodies 1 are relatively plugged. The optical axes 1-1 are respectively embedded in the upper top and lower bottom of the through grooves on both sides of the short rail body to form a longitudinal sliding track. In the cutting device 3, the U-groove bearing 5-10 is clamped by the longitudinal sliding track to form a seamless sliding fit. The optical axis 1-1 is a shaft or a tube.

[0023] Refer to the appendix Figure 2 . The upper surface of the short rail body 1 is designed with a step 1-4 to cooperate with the upper slot 6-5-1 on the suction cup. The optical axis 1-1 on the short rail body cooperates with the guide rail 1-2. The upper surface of the guide rail body 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 short rail body 1 and the connecting connector 6-2 are spliced by tightening the lock washer nut 6-1.

[0024] Refer to the appendix Figure 2-7 . The short rail body 1 is in butt-joint plugging cooperation with the front and back of the suction cup 2, and the side surface of the short rail body 1 is connected by plugging through the optical axis 1-1.

[0025] 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 grooves. 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 inserted together to form a hoop-type U-groove bearing sliding track. The relatively exposed surfaces of the hoop-type U-groove bearing sliding guide are in sliding fit with the U-groove bearing in the cutting device.

[0026] The through grooves on the butt joint surfaces of both sides of the short rail body 1 are seamlessly butted in a staggered manner. See Figure 2 .

[0027] 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 lock grooves 1-5.

[0028] 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 piece 6-2. T-shaped slots 6-2-1 are opened on both sides of the vertical rod of the inverted T-shaped rail connecting piece 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 lock groove 1-5 to fix the T-shaped rail connecting piece 6-2 and the reverse top lock groove 1-5 into one body.

[0029] 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.

[0030] Characteristics of the short rail body structure: The short 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 arranged in a staggered manner as Figure 7 shown. The staggered arrangement is for, on the one hand, better splicing of the rails, and on the other hand, when the slider slides on the rail, the staggered arrangement is beneficial to the smooth sliding of the slider on the rail.

[0031] A "T" - shaped slot 1-5 is designed on the short 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 piece 6-2 to ensure no misalignment connection between the rails. Refer to the appendix Figure 8The 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 joint surface of the suction cup main body 6-5 and the short rail body 1 is arc-shaped, and a groove 6-5-2 and a clamping groove 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-joint surface with the short rail body 1, and the bottom of the suction cup main body on the non-joint surface of 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.

[0032] 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.

[0033] Refer to the appendix Figure 15 In the cutting device 3, square grooves 5-12-1 are provided at the lower parts on both sides of the carriage 5-12. The square grooves 5-12-1 cooperate with square nuts 5-13. The slider 5-12 is designed with a threaded hole 5-12-2, and the threaded hole 5-12-2 cooperates with a top-tightening screw 5-14. The top-tightening screw 5-14 tightens the square nut 5-13. By adjusting the tightness of the top-tightening screw 5-14, the height of the U-shaped groove bearing 5-10 is adjusted to ensure that the slider moves without clearance and smoothly on the guide rail; the U-shaped groove bearings 5-10 are distributed in two rows, one in front and one behind, and the U-shaped groove bearings 5-10 are in seamless fit with the smooth shaft 1-1 surface on the guide rail 1.

[0034] In the cutting device 3, the length of the handle 5-4 is greater than 20 cm. A cutter wheel 5-6 is installed on one side of the handle 5-4. The cutter wheel is installed on the handle 5-4 through a screw 5-8. A side wheel 5-2 is installed on one side of the handle 5-4. The side wheel 5-2 is connected to the handle 5-4 through a screw 5-1 and a nut 5-3. The handle 5-4 is connected to the carriage 5-12 through a screw 5-7. The handle 5-4 is connected to the carriage 5-12.

[0035] Characteristics of the cutting device: The U-shaped groove bearings 5-10 on the slider 5-12 of the cutting device 5 are arranged in two rows, upper and lower, and are in seamless fit with the round steel 1-1 on the guide rail 1. The advantage of this is that it can ensure the smooth sliding of the cutting system on the guide rail 1 and can also improve the bending strength of the guide rail 1.

[0036] An extended handle 5-4 is adopted. A cutting wheel (blade) 5-6 is installed on one side of the handle 5-4. The blade is fixed to the handle 5-4 by screws 5-8. A lateral wheel 5-2 is installed on the other side. The lateral wheel 5-2 is connected to the handle 5-4 by screws 5-1 and nuts 5-3. The handle 5-4 is connected to the carriage 5-12 by screws 5-7. The handle 5-4 is distributed with the slider 5-12 and extended. The advantages are: the left and right forces are evenly distributed, it is relatively easy to cut, a relatively large force can be applied arbitrarily, and the surface enamel of the board can be cut through.

[0037] A plurality of U-shaped groove bearings 5-10 are installed on the carriage 5-12. One type of U-shaped groove bearing 5-10 is fixed to the carriage 5-12 through a gasket 5-9 and screws 5-11. Another type is fixed to the slider 5-12 through a gasket 5-9, screws 5-11, and a square nut 5-13. A square groove 5-12-1 is designed on the slider 5-12. The square groove 5-12-1 cooperates with the square nut 5-13. A threaded hole 5-12-2 is designed on the slider 5-12. The threaded hole 5-12-2 cooperates with the tightening screw 5-14. The tightening screw 5-14 tightens the square nut 5-13. By adjusting the tightness of the tightening screw 5-14, the height of the U-shaped groove bearing 5-10 is adjusted to ensure that the slider moves without clearance and smoothly on the guide rail.

[0038] The spring 5-5 can ensure that the handle 5-4 bounces up freely.

[0039] 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.
