Description

Technical Field

[0001] The present invention relates to the technical field of flat creasing, creasing and cutting machines, and in particular to a flat creasing, creasing and cutting machine for processing paper cup sector sheets and a use method thereof. Background Art

[0002] In the modern packaging products industry, paper cups are a common disposable packaging container. Their production process usually includes two main steps: cutting and shaping. The cutting step involves cutting the paper into the appropriate shape to form the paper cup, while the shaping step is to shape the cut paper into the shape of the paper cup. In order to achieve these two steps, a device is usually used, namely a flat creasing and tangent cutting machine.

[0003] A flatbed creasing and tangent machine is a device that indents paper to create paper sheets with specific patterns, which are then shaped into paper cups through other equipment. It works by using a pair of pressing rollers to create paper sheets with specific patterns. However, existing flatbed creasing and tangent machines have some problems.

[0004] Firstly, existing flat creasing and slitting machines can usually only process paper sheets of one size and cannot be adjusted for paper sheets of different sizes. This means that if you want to make paper cups of different sizes, you need to replace different equipment, which obviously increases production costs and time.

[0005] Secondly, the existing flat creasing and embossing and cutting machines cannot quickly replace the pressing rollers with different patterns during use. This means that if different patterns of indentations need to be made, the machine needs to be stopped and the pressing rollers need to be replaced, which will undoubtedly affect production efficiency. Therefore, the existing flat creasing and embossing and cutting machines cannot meet the needs of the modern packaging products industry, especially for companies that need to produce paper cups of various sizes and patterns. Their efficiency and adaptability are relatively low. Summary of the Invention

[0006] The purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art and to provide a flat creasing and slitting machine for processing paper cup fan-shaped sheets and a method of use, so as to solve the problems that the existing flat creasing and slitting machines cannot be adjusted for paper sheets of different sizes and cannot quickly replace pressure rollers with different patterns during use.

A first motor is fixedly provided on one side of the feeding platform, and the first motor is used to drive the conveyor belt to move. A second motor and a third motor are respectively provided on the outer walls of both sides of the mounting frame, and the third motor is used to drive the two second rotating shafts to rotate, and the second motor is used to drive the first gear to rotate. A plurality of legs are installed at the bottom of the feeding platform, and a material receiving box is fixedly provided on one side of the mounting frame.

[0008] Furthermore, first rotating shafts are rotatably installed on both sides of the feeding platform, and transmission rollers are fixedly sleeved on the two first rotating shafts. The two ends of the inner wall of the conveyor belt are respectively sleeved on the outer walls of the two transmission rollers and adapted thereto. The output end of the first motor passes through one side of the feeding platform and is fixedly connected to one end of one of the first rotating shafts.

[0009] Furthermore, one end of each of the two second rotating shafts passes through one side of the mounting frame and extends to the outside, and one end of the two second rotating shafts is respectively fixedly sleeved with a first synchronous wheel and a second synchronous wheel, and the first synchronous wheel and the second synchronous wheel are sleeved with the same synchronous belt, and the output end of the third motor is fixedly connected to one of the second rotating shafts.

[0011] Furthermore, one end of the fourth rotating shaft is sleeved with a sliding sleeve, and a plurality of protrusions are fixedly installed on the inner wall of the sliding sleeve, and a plurality of sliding grooves are clamped on the outer wall of the fourth rotating shaft, and a plurality of the protrusions are inserted into the corresponding sliding grooves and slidably connected thereto, the second gear is fixedly sleeved on one end of the sliding sleeve, and the other end of the sliding sleeve is sleeved with a connecting plate, and the connecting plate is rotatably connected to the sliding sleeve, an electric push rod is fixedly installed on the outer wall of one side of the mounting frame, and the output end of the electric push rod passes through one side of the mounting frame and is fixedly connected to one end of the connecting plate.

[0012] Furthermore, locking rods are provided at both ends of the two limit plates, and the locking rods are slidably connected to the limit plates.

[0017] When the creasing roller needs to be replaced, the connecting plate is driven to move by the electric push rod, so that the sliding sleeve moves along the fourth rotating shaft. Since the second gear is fixed on the sliding sleeve, when the sliding sleeve moves, the second gear can be disengaged from the first gear. After disengagement, the third motor is driven to drive the two second rotating shafts to rotate synchronously. At the same time, the two creasing rollers can be quickly replaced. After the replacement is completed, the electric push rod is driven again to return to the initial position, and the first gear and the second gear are re-engaged.

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. The present invention can quickly replace creasing rollers with different patterns through the provision of a sliding sleeve. This is mainly due to the unique sliding sleeve movement mechanism inside the machine, which enables the creasing roller and the driving gear to be quickly separated and replaced without tedious manual operations, greatly saving time and manpower.

[0021] 2. This invention can effectively process paper sheets of different sizes. The height of the baffle can be adjusted by a threaded rod to accommodate paper of varying thicknesses. The machine's limit plate ensures accurate positioning of paper sheets as they enter the machine. This design improves product processing precision and quality, significantly reducing the scrap rate of paper cups. BRIEF DESCRIPTION OF THE DRAWINGS

A first motor 6 is fixedly provided on one side of the feeding platform 1, and the first motor 6 is used to drive the conveyor belt 4 to move. A second motor 14 and a third motor 26 are respectively provided on the outer walls of both sides of the mounting frame 13, and the third motor 26 is used to drive the two second rotating shafts 22 to rotate, and the second motor 14 is used to drive the first gear 9 to rotate. A plurality of legs 2 are installed at the bottom of the feeding platform 1, and a material receiving box 11 is fixedly provided on one side of the mounting frame 13. The paper enters the machine through the conveyor belt 4 on the feeding platform 1. Limit plates 7 are provided on both sides of the conveyor belt 4 to ensure that the position of the paper is accurate when entering the machine. The movement of the conveyor belt 4 is driven by the first motor 6. At the same time, the baffle 8 can adapt to paper of different thicknesses by adjusting the height of the threaded rod 17 to ensure that the paper enters the machine smoothly; when the paper passes through the two indentation rollers 10, the indentation processing of the paper is completed.

[0046] The first rotating shafts 5 are rotatably installed on both sides of the feeding platform 1, and the two first rotating shafts 5 are fixedly sleeved with transmission rollers 3. The two ends of the inner wall of the conveyor belt 4 are respectively sleeved on the outer walls of the two transmission rollers 3 and adapted to them. The output end of the first motor 6 passes through one side of the feeding platform 1 and is fixedly connected to one end of one of the first rotating shafts 5.

[0047] One end of each of the two second rotating shafts 22 passes through one side of the mounting frame 13 and extends to the outside, and one end of the two second rotating shafts 22 is fixedly sleeved with a first synchronous wheel 23 and a second synchronous wheel 25, respectively. The first synchronous wheel 23 and the second synchronous wheel 25 are sleeved with the same synchronous belt 24, and the output end of the third motor 26 is fixedly connected to one of the second rotating shafts 22.

[0048] A fourth rotating shaft 29 is rotatably mounted on an inner wall of one side of the mounting frame 13, and a second gear 20 is fixedly provided at one end of the fourth rotating shaft 29. The second gear 20 is engaged with one of the first gears 9. The other end of the fourth rotating shaft 29 passes through one side of the mounting frame 13 and extends to the outside. The output end of the second motor 14 is fixedly connected to one end of the fourth rotating shaft 29.

[0049] One end of the fourth rotating shaft 29 is provided with a sliding sleeve 30, and a plurality of protrusions 33 are fixedly installed on the inner wall of the sliding sleeve 30. A plurality of sliding grooves 32 are provided on the outer wall of the fourth rotating shaft 29. The plurality of protrusions 33 are inserted into the corresponding sliding grooves 32 and are slidably connected thereto. The second gear 20 is fixedly sleeved on one end of the sliding sleeve 30, and a connecting plate 31 is sleeved on the other end of the sliding sleeve 30, and the connecting plate 31 is rotatably connected to the sliding sleeve 30. An electric push rod 12 is fixedly installed on the outer wall of one side of the mounting frame 13, and the output end of the electric push rod 12 passes through one side of the mounting frame 13 and is fixedly connected to one end of the connecting plate 31. Next, when the creasing roller 10 needs to be replaced, the connecting plate 31 is driven to move by the electric push rod 12, so that the sleeve 30 moves along the fourth rotating shaft 29. Since the second gear 20 is fixed on the sleeve 30, when the sleeve 30 moves, the second gear 20 can be disengaged from the first gear 9. After disengagement, the third motor 26 is driven to drive the two second rotating shafts 22 to rotate synchronously. At the same time, the two creasing rollers 10 can be quickly replaced. After the replacement is completed, the electric push rod 12 is driven again to return to the initial position, and its first gear 9 and the second gear 20 are re-engaged.

[0050] Both ends of the two limit plates 7 are penetrated by locking rods 19, and the locking rods 19 are slidably connected to the limit plates 7. Multiple groups of limit holes 18 are opened on the upper part of the feeding table 1, and one end of multiple locking rods 19 is inserted into the corresponding limit holes 18 and adapted thereto.

[0051] Two guide columns 16 are fixedly installed on the upper part of the feeding table 1, and the two guide columns 16 respectively pass through the two ends of the baffle 8 and are slidably connected thereto. One end of the threaded rod 17 passes through the baffle 8 and is threadedly connected thereto. The baffle 8 can adapt to paper of different thicknesses by adjusting the height of the threaded rod 17, ensuring that the paper enters the machine smoothly, which is extremely practical.

[0052] A method for using a flat creasing and cutting machine for processing paper cup fan-shaped sheets comprises the following steps:

[0053] The paper enters the machine through the conveyor belt 4 on the feeding platform 1. The conveyor belt 4 is provided with limit plates 7 on both sides to ensure the accurate position of the paper when entering the machine. The movement of the conveyor belt 4 is driven by the first motor 6. At the same time, the baffle 8 can adapt to different thicknesses of paper by adjusting the height of the threaded rod 17 to ensure that the paper enters the machine smoothly.

[0054] When the paper passes through the two creasing rollers 10, the second motor 14 is started to drive the second gear 20 to rotate. At the same time, the second gear 20 drives the first gear 9 meshed with it to rotate synchronously. Then, the two creasing rollers 10 will rotate synchronously, thereby completing the creasing process on the paper.

[0055] When the creasing roller 10 needs to be replaced, the connecting plate 31 is driven to move by the electric push rod 12, so that the sliding sleeve 30 moves along the fourth rotating shaft 29. Since the second gear 20 is fixed on the sliding sleeve 30, when the sliding sleeve 30 moves, the second gear 20 can be disengaged from the first gear 9. After disengagement, the third motor 26 is driven to drive the two second rotating shafts 22 to rotate synchronously. At the same time, the two creasing rollers 10 can be quickly replaced. After the replacement is completed, the electric push rod 12 is driven again to return to the initial position, and the first gear 9 and the second gear 20 are re-engaged.

[0056] The processed paper materials are collected through the receiving box 11 to facilitate subsequent processing and use.

[0057] Example 2:

[0058] like Figure 9 As shown, compared with the embodiment 1, the embodiment is mainly improved on the feeding platform 1. Specifically, two movable grooves 34 are provided on the upper part of the feeding platform 1, and two guide rods 36 are fixedly installed in the two movable grooves 34. One end of the two limit plates 7 is respectively located in the corresponding movable grooves 34. The two limit plates 7 are respectively penetrated by the corresponding two guide rods 36 and slidably connected thereto. A threaded column 37 is rotatably installed on one side of one movable groove 34, and the other end of the threaded column 37 sequentially penetrates the two limit plates 7 and the two movable grooves 34 and extends to the outside. A fixed outer wall on one side of the feeding platform 1 A servo motor 35 is installed, and the output end of the servo motor 35 is fixedly connected to one end of a threaded column 37. Two threaded grooves are opened on the threaded column 37, and the threaded grooves at both ends are opened in opposite directions. The two limit plates 7 are respectively threadedly connected to the threaded grooves at both ends on the threaded column 37. When the two limit plates 7 need to be adjusted to adapt to fan-shaped paperboards of different sizes, it is only necessary to start the servo motor 35 and drive the threaded column 37 to rotate. Since the threads at both ends are opened in opposite directions, the two limit plates 7 move in opposite directions synchronously. Finally, the limit plates 7 are adjusted to the appropriate position, which is extremely convenient and quick to operate.

[0059] Example 3:

[0060] like Figures 10 to 16 As shown, in this embodiment, the indentation roller 10 on the mounting frame 13 and the switching structure of the indentation roller 10 are mainly improved. Specifically, a flat creasing and cutting machine for processing paper cup fan-shaped sheets is provided. A first rotating frame 101 is rotatably provided in the mounting frame 13, a lifting frame 102 is provided above the mounting frame 13, and a second rotating frame 103 is rotatably provided in the lifting frame 102. The first rotating frame 101 includes a rotating frame shaft 104 and two rotating frame plates 105 arranged on the rotating frame shaft 104 at a certain distance. The outer edges of the two rotating frame plates 105 are connected to the rotating frame shaft 104. A plurality of indentation roller assemblies 106 are arranged around the center, and the indentation roller assembly 106 includes an axis body 107, an indentation roller arranged on the periphery of the axis body 107, and a telescopic fixing structure 200 arranged at both ends of the axis body 107. The indentation roller rotates synchronously with the axis body 107. One end of the rotating frame shaft 104 is connected to a driving device 108, such as a servo motor, which has high precision and good controllability. The telescopic fixing structure 200 enables the indentation roller assembly 106 to have a first state in which the two rotate synchronously relative to the first rotating frame 101 and a second state in which the indentation roller assembly 106 rotates on its own.

[0061] The structure of the second rotating frame 103 is the same as that of the first rotating frame 101. A switching station is provided on the side of the mounting frame 13 close to the lifting frame 102, and a switching station is also provided on the side of the lifting frame 102 close to the mounting frame 13. The paper passes between the two creasing rollers of the creasing roller assembly 106 at the switching station, so that the paper can be creasing.

[0062] A disengagement mechanism 300 is provided at both ends of each switching station. The disengagement mechanism 300 is used to disengage the indentation roller assembly 106 from the corresponding turntable when the indentation roller assembly 106 rotates to the switching station and can rotate on its own, that is, switch from the first state to the second state, thereby installing the required indentation roller assembly 106 on the two turntables, and then controlling the rotation of the turntable by the driving device 108 to rotate the required indentation roller assembly 106 to the switching station, and then the disengagement mechanism 300 is actuated to disengage the two indentation roller assemblies 106 from the corresponding turntables, and the two indentation roller assemblies 106 can perform indentation processing on the paper material, and at the same time, the rapid switching of the indentation roller assembly 106 can be realized without manual intervention, with a higher degree of automation, and can improve production efficiency.

[0063] The telescopic fixing structure 200 includes a first slide 201, a telescopic rod 202 and an elastic member 203 provided at both ends of the shaft body 107. The first slide 201 includes a first channel portion 2011 and a second channel portion 2012 that are connected. The first channel portion 2011 is close to the rotating frame plate 105, and the inner diameter of the second channel portion 2012 is larger than the inner diameter of the first channel portion 2011. The telescopic rod 202 includes a limiting portion 2021 slidably provided in the second channel portion 2012 and a limiting portion 2021 slidably provided in the first channel portion 2012. A fixing portion 2022 within the channel portion 2011 limits the telescopic rod 202's telescopic travel, preventing it from detaching from the first slideway 201. The turret plate 105 includes a corresponding fixing hole 204 for insertion into each fixing portion 2022. The number of fixing holes 204 is no less than the number of creasing roller assemblies 106. This allows for a plurality of fixing holes 204 to be provided, allowing the desired number of creasing roller assemblies 106 to be installed based on actual production needs, thereby enhancing the machine's applicability and practicality. The turret shaft body 107 comprises two mate-connected half-axles 1071, facilitating the machining of the first slideway 201 and the installation of the telescopic rod 202 and elastic member 203.

[0064] After the fixing portion 2022 is inserted into the fixing hole 204, it is fixed so that the rotary frame shaft 104 will not rotate relative to the first rotary frame 101, which is the first state. The fixing portion 2022 and the fixing hole 204 are polygonal. In this embodiment, the fixing portion 2022 is a square rod and the fixing hole 204 is a square hole. The elastic member 203 is arranged in the second channel portion 2012, and the two ends of the elastic member 203 are respectively abutted against the limiting portion 2021 and the bottom of the second channel portion 2012. The elastic member 203 adopts a columnar spring. When the elastic member 203 is in a normal state, the telescopic rod 202 is in the maximum extension state, that is, the fixing portion 2022 is inserted into or passes through the fixing hole 204. At this time, the driving device 108 drives the first rotary frame 101 to rotate and can choose to switch to the required indentation roller for processing.

[0065] The disengagement mechanism 300 includes a linkage rod 301 arranged to move along the telescopic direction of the telescopic rod 202, a disengagement cylinder 302 that drives the linkage rod 301 to move in the telescopic direction of the telescopic rod 202, and a rotating support member 304 rotatably arranged on the mounting frame or the lifting frame 102. The linkage rod 301 includes a first rod portion 401, a second rod portion 402 and a third rod portion 403 arranged in sequence. The driving rod of the disengagement cylinder 302 abuts against the first rod portion 401. The mounting frame or the lifting frame 102 is provided with a through hole 305 corresponding to the rotating support member 304. A second slide 306 is provided at the center of the rotating support member 304. The first slide 201, the telescopic rod 202, the linkage rod 301, the second slide 306 and the through hole 305 are all coaxially arranged.

[0066] In this embodiment, the first rod portion 401 is a square rod, the second rod portion 402 is a round rod, and the third rod portion 403 is a square rod that is compatible with the fixing hole 204 and the first channel portion 2011. The second rod portion 402 can rotate in the fixing hole 204, and the second slide 306 is a square channel that is compatible with the first rod portion 401. A pair of rotating supports 304 located on the same side are provided with meshing gear portions 3041 on the outside, and one side of one of the gear portions 3041 is provided with a meshing main drive gear 501. The other pair of rotating supports 304 on the same side can be provided with meshing gear portions 3041 on the outside or not. The main drive gear 501 is connected to a drive motor 502, which adopts a servo motor. The drive motor 502 drives the two indentation roller assemblies 106 to rotate to perform indentation processing on the paper.

[0067] When the telescopic rod 202 is in the first state, the third rod portion 403 is located outside the fixing hole 204 and the first rod portion 401 passes through the second slide 306. At this time, the first rotating frame 101 and the second rotating frame 103 can drive the creasing roller assemblies 106 thereon to rotate and switch.

[0068] When the disengagement cylinder 302 pushes the linkage rod 301 to move toward the indentation roller assembly 106, the telescopic rod 202 switches from the first state to the second state. At this time, the third rod portion 403 passes through the fixing hole 204 and is inserted into the first channel portion 2011, and the fixing portion 2022 is separated from the fixing hole 204 and retracted into the first channel portion 2011. At the same time, the first rod portion 401 passes through the second slide 306 and the second rod portion 402 passes through the fixing hole 204. In this way, the rotating support 304, the linkage rod 301 and the indentation roller assembly 106 rotate synchronously and can rotate relative to the rotating frame. Specifically, the main driving gear 501 is driven to rotate by the driving motor 502, and the two rotating supports 304 with the gear portion 3041 rotate synchronously, driving the corresponding linkage rod 301 to rotate, and the linkage rod 301 drives the corresponding indentation roller assembly 106 to rotate to perform indentation processing on the paper.

[0069] When the telescopic rod 202 needs to return to the first state from the second state, the driving rod separated from the cylinder 302 retreats, and the elastic member 203 recovers its elastic deformation so that the telescopic rod 202 pushes the linkage rod 301 back to its original position.

[0070] Furthermore, a cylinder lifting assembly 601 is provided between the mounting frame and the lifting frame 102. The cylinder lifting assembly 601 can drive the lifting frame 102 to move up and down relative to the mounting frame, so that the two creasing roller assemblies 106 of the switching station are separated or approached, which facilitates the rapid disassembly and assembly of the creasing roller assembly 106 and the threading of the paper material.

[0071] Furthermore, an elastic member limiting column 205 is provided at the bottom of the second channel portion 2012, and an elastic member limiting groove 206 is provided on the side of the limiting portion 2021 facing the elastic member 203 to prevent the elastic member 203 from moving when the telescopic rod 202 moves, thereby improving the stability and reliability of the mechanism movement.

[0072] Furthermore, an arc-shaped top is provided at the end of the fixing portion 2022, and an arc-shaped top is also provided at the end of the third rod portion 403 facing the fixing portion 2022, thereby reducing the frictional resistance between the two in the first state and reducing friction loss; an arc-shaped top is provided at the end of the drive rod of the disengagement cylinder 302, and an arc-shaped top is also provided at the end of the first rod portion 401 facing the drive rod, thereby reducing the frictional resistance between the two in the second state and reducing friction loss.

[0073] Furthermore, the rotating frame plate 105 is provided with a disassembly and assembly slot 207 corresponding to each fixing hole 204 , and the end of the fixing portion 2022 is provided with an arc-shaped top to facilitate movement in the disassembly and assembly slot 207 , thereby improving the disassembly and assembly efficiency of the creasing roller assembly 106 .

[0074] Furthermore, the mounting frame and the lifting frame 102 are both provided with detection sensors 700 corresponding to the telescopic rod 202, and a detection point is correspondingly provided on one side wall of the first rod portion 401. The detection sensor 700 is used to detect whether the side wall has turned to a horizontal state, that is, whether it is in the correct position for switching the workstation. The detection sensor 700 can adopt a laser ranging sensor or an infrared ranging sensor, so as to ensure that the third rod portion 403 is aligned with the fixing hole 204. Generally, the detection is performed when the telescopic rod 202 is in the second state. If it is detected that the third rod portion 403 is not horizontal, the driving motor 502 drives the indentation roller assembly 106 to rotate and drive the third rod portion 403 to adjust.

[0075] In the first embodiment, for each corresponding group of two creasing rollers 10, only one group can be replaced each time the adjustment is performed. In the present embodiment, a single creasing roller 10 in a group can be replaced, and the overall disassembly and replacement is more convenient, and the repair and maintenance costs are lower.

[0076] A method for using a flat creasing and cutting machine for processing paper cup fan-shaped sheets comprises the following steps:

[0077] The required creasing roller assembly 106 is rotated into the first rotating frame and the second rotating frame along the disassembly and assembly chute 207. The telescopic rods 202 at both ends of the creasing roller assembly 106 are inserted into the fixing holes 204 to fix them. At this time, the rotating frame and the creasing roller assembly 106 thereon rotate synchronously.

[0078] The driving device 108 drives the corresponding rotating frame to rotate so that the required creasing roller assembly 106 is transferred to the switching position. Then, the cylinder 302 is disengaged to push the linkage rod 301 toward the telescopic rod 202. The third rod portion 403 passes through the fixing hole 204 and is inserted into the first channel portion 2011. The telescopic rod 202 retracts into the first channel portion 2011. At this time, the creasing roller assembly 106 at the switching position can rotate relative to the corresponding rotating frame.

[0079] The driving motor 502 drives the two creasing roller assemblies 106 to rotate through gear transmission to perform creasing treatment on the paper;

[0080] When the indentation roller assembly 106 needs to be replaced, the driving rod separated from the cylinder 302 retreats, and the elastic member 203 restores its elastic deformation so that the telescopic rod 202 pushes the linkage rod 301 back to its original position. At this time, the turntable and the indentation roller assembly 106 on it rotate synchronously, and the corresponding turntable can be driven to rotate by the driving device 108 so that the required indentation roller assembly 106 is moved to the switching position.

[0081] Example 4:

[0082] like Figure 17 As shown, on the basis of Example 3, this embodiment further solves the problem of alignment of the third rod portion 403 and the fixing hole 204, and an anti-deflection mechanism 800 is provided on one side of the first rod portion 401, and the anti-deflection mechanism 800 includes an anti-deflection cylinder and an anti-deflection block, and the pressing end surface of the anti-deflection block is a horizontal plane. When the first rotating frame 101 or the second rotating frame 103 rotates to switch the indentation roller assembly 106, the anti-deflection cylinder drives the pressing end surface of the anti-deflection block to abut against the first rod portion 401, so as to prevent it from deflecting when the indentation roller assembly 106 is switched, resulting in misalignment with the fixing hole 204. When it is subsequently switched to the second state, the third rod portion 403 cannot pass through the fixing hole 204. After the indentation roller assembly 106 is switched or the third rod portion 403 is inserted into the first channel portion 2011, the anti-deflection block retracts and does not affect the rotation of the first rod portion 401.

[0083] A method for using a flat creasing and creas- ing machine for processing paper cup sector pieces includes the following steps: when replacing the creasing roller assembly 106, the anti-deflection cylinder drives the pressing end surface of the anti-deflection block to abut against the first rod portion 401.

[0084] The above disclosure is merely a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
