Description

Technical Field

[0001] This utility model relates to the field of a leather cutting machine with three longitudinal beams, and more particularly to a three longitudinal beam cutting machine. Background Technology

[0002] A leather cutting machine is a device that cuts out corresponding patterns from leather.

[0003] Currently, in response to customer requirements, there is a need to improve the overall efficiency of the cutting machine. According to the design of traditional cutting machines, such as the one described in patent number 202410716701.9 (titled "A Leather Production Cutting and Processing Device"), the structure of this equipment shows relatively low production capacity and limited functionality. Specifically:

[0004] First, the patent in question uses a single cutting head, which is mounted on a moving device. It should be noted that the patterns can be complex and varied according to the customer's requirements. Relying on only one cutting head is obviously insufficient to meet the customer's production capacity requirements.

[0005] Secondly, the cutting head only has a cutting function. In reality, customers may need to create holes in the leather at the request of consumers or products. For customers with this need, the single function leads them to purchase another punching machine to punch holes in the leather. For customers, this method will increase costs significantly. At the same time, purchasing punching equipment will reduce the workshop space, causing space anxiety. Utility Model Content

[0006] To address the aforementioned issues, this invention provides a three-beam cutting machine, which solves the capacity problem by selecting a larger number of cutting devices and adding a new layout.

[0007] This utility model provides a three-beam cutting machine, which also solves the problem of single function. By integrating the cutting and punching functions into one device, it can achieve both cutting and punching effects. Combined with a specific layout, it can handle complex patterns and significantly improve the overall cutting efficiency.

[0008] To achieve the above objectives, the technical solution adopted by this utility model is: a three-beam cutting machine, comprising a cutting platform and a cutting device suspended on the cutting platform via a moving assembly, characterized in that the cutting device is a cutting head with simultaneous cutting and punching functions, characterized in that there are three cutting heads, wherein the cutting heads are configured in any one or more of the following arrangements: alternating arrangement, unidirectional arrangement, symmetrical layout.

[0009] The beneficial effects of this utility model are:

[0010] 1. First, this utility model adopts a new layout method, which has three parts: alternating arrangement, unidirectional arrangement, and symmetrical layout. When faced with different complex patterns, the corresponding selection and setting method can obtain the most ideal cutting efficiency. In particular, some customers require special shapes in the constituent elements of the pattern. The specific selection of the layout method can reduce the number of times the cutting head moves. In other words, in the unit time to complete such a pattern with special shapes, the effective working time of the cutting head of this application is higher than that of the cutting head in the prior art, thereby significantly improving the utilization rate of the equipment.

[0011] 2. Secondly, the increased functionality brings greater feasibility to production projects. It allows for both cutting and punching of the leather, resulting in a more significant improvement in cutting efficiency by eliminating interference and achieving a synergistic effect during execution. It also replaces the need for additional punching equipment, allowing for more efficient optimization of the process flow and space utilization. Combined with the aforementioned layout, the greater variety of space combinations further enhances the cutting efficiency.

[0012] In a preferred embodiment, the moving assembly includes a drive section and longitudinal beams, the number of which corresponds to the number of cutting heads; wherein, the longitudinal beams are load-bearing components that provide superior load-bearing capacity, and the drive section is the power source that drives the longitudinal beams to move (the output end of the drive section is connected to the longitudinal beams).

[0013] In fact, the present invention, a three-beam cutting machine, includes a frame, a drive unit mounted on the longitudinal beams, and the longitudinal beams and the frame are slidably connected.

[0014] Regarding the various arrangements of alternating, unidirectional, and symmetrical layouts, alternating arrangement refers to an arrangement where the first cutting head is located on the right side of the longitudinal beam, and the second cutting head is located on the left side of the longitudinal beam, with the two cutting heads facing away from each other; unidirectional arrangement refers to an arrangement where the first cutting head is located on the right side of the longitudinal beam, and the second cutting head is located on the right side of the longitudinal beam, with the two cutting heads facing the same direction; symmetrical layout refers to an arrangement where the first cutting head is located on the left side of the longitudinal beam, and the second cutting head is located on the right side of the longitudinal beam, with the two cutting heads facing each other.

[0015] In the first embodiment, all three cutting heads are located on the right side of their respective longitudinal beams. In the second embodiment, the first cutting head is located on the right side of its longitudinal beam, while the second and third cutting heads are located on the left side of their respective longitudinal beams. In the third embodiment, the first and second cutting heads are located on the right side of their respective longitudinal beams, while the third cutting head is located on the left side of their respective longitudinal beams. In the fourth embodiment, all three cutting heads are located on the left side of their respective longitudinal beams. Of course, other embodiments are also possible. The above are just examples. Depending on the requirements, the cutting heads can be freely selected from alternating arrangements, unidirectional arrangements, and symmetrical layouts.

[0016] In fact, the cutting head is an existing component in the industry. For example, the utility model patent with patent number 202322467017.5 entitled "A Double Blade Head" can also provide the marking function required for cutting leather, and can also mark lines during punching and cutting.

[0017] The drive section has two implementation methods: biased drive motor and mid-mounted drive motor. The mid-mounted drive motor scheme has higher synchronization. The mid-mounted drive motor scheme includes:

[0018] The system includes a motor mounting base, a first drive motor, a first transmission roller, a transmission roller mounting base, a front support plate, a first drive wheel, a first driven wheel, a second driven wheel, a third driven wheel, a rack, and a driven gear. Two front support plates are provided, each connected to the bottom of one end of the longitudinal beam. A slider is located on the inner surface of the front support plate and slidably connected to a first track on the bottom side of the frame. The rack is also located on the bottom side of the frame. The motor mounting base and transmission roller mounting base are both located on the side of the longitudinal beam. At least two transmission roller mounting bases are provided, with the motor mounting base located between the two transmission roller mounting bases. The first transmission roller passes through the two transmission roller mounting bases and the motor mounting base, and is fixed to the longitudinal beam via the transmission roller mounting base. The first drive motor is mounted on the motor mounting base and corresponds to the first driven wheel in the middle area of ​​the first transmission roller. The output shaft of the first drive motor... The system includes a first drive wheel, which is connected to the first driven wheel via a belt drive. A second driven wheel is mounted on both ends of the first transmission roller. A third synchronous wheel is located on the outer surface of the front support plate, and the second and third driven wheels are connected via a belt drive. A driven gear is located on the inner side of the front support plate and is connected to the third driven wheel via a rotating shaft. When the third driven wheel rotates, it drives the driven gear to rotate, which in turn meshes with a rack. This design ensures that the instantaneous response of the rotation at both ends of the first transmission roller is synchronized. As is well known, rigid torsion is the phenomenon of relative rotation between cross sections of an object under torque. Therefore, to avoid asynchronous rotation at both ends of the second transmission roller, a centrally located motor can solve the lag problem caused by asynchronous rotation at both ends.

[0019] The drive motor bias solution is more economical and easier to assemble, making it suitable for customers with lower precision requirements.

[0020] The main difference between the offset drive motor scheme and the center-mounted drive motor scheme lies in their positional relationship. Specifically, the offset drive motor scheme includes a second transmission roller, a second drive motor, a fourth transmission wheel, and a second drive wheel. The second drive motor is mounted on the side of one end of the longitudinal beam. The fourth transmission wheel and the second drive wheel are respectively mounted on the transmission roller mounting seats at both ends of the longitudinal beam. The second transmission roller is simultaneously fitted by both the second drive wheel and the fourth transmission wheel. The second drive wheel is mounted on the motor shaft of the second drive motor. Under the action of the second drive motor, the second drive wheel and the fourth transmission wheel also rotate. The second drive wheel and the fourth transmission wheel are each fitted with a belt, which drives the third driven wheel to rotate. When the third driven wheel rotates, it drives the driven gear to rotate. The driven gear meshes with the rack, thus ultimately achieving the effect of gear transmission. Attached Figure Description

[0031] A three-beam cutting machine includes a cutting platform 1 and a cutting device suspended on the cutting platform 1 via a moving assembly 2. The cutting device is characterized in that it is a cutting head with simultaneous cutting and punching functions. The cutting head is provided in three parts, wherein the cutting heads are arranged in any one of the following arrangements: alternating, unidirectional, or symmetrical.

[0032] The beneficial effects of this utility model are:

[0033] 1. First, this utility model adopts a new layout method, which has three parts: alternating arrangement, unidirectional arrangement, and symmetrical layout. When faced with different complex patterns, the corresponding selection and setting method can obtain the most ideal cutting efficiency. In particular, some customers require special shapes in the constituent elements of the pattern. The specific selection of the layout method can reduce the number of times the cutting head moves. In other words, in the unit time to complete such a pattern with special shapes, the effective working time of the cutting head of this application is higher than that of the cutting head in the prior art, thereby significantly improving the utilization rate of the equipment.

[0034] 2. Secondly, the increased functionality brings greater feasibility to production projects. It allows for both cutting and punching of the leather, resulting in a more significant improvement in cutting efficiency by eliminating interference and achieving a synergistic effect during execution. It also replaces the need for additional punching equipment, allowing for more efficient optimization of the process flow and space utilization. Combined with the aforementioned layout, the greater variety of space combinations further enhances the cutting efficiency.

[0035] In a preferred embodiment, the moving assembly 2 includes a drive section and a longitudinal beam 21, the number of which corresponds to the number of cutting heads; wherein, the longitudinal beam 21 is a load-bearing member that provides a better load force, and the drive section is the power source that drives the longitudinal beam 21 to move (the output end of the drive section is connected to the longitudinal beam 21).

[0036] In fact, the three-beam cutting machine of this utility model includes a frame 4, and the drive part is set on the longitudinal beam 21. The longitudinal beam 21 and the frame 4 are slidably connected.

[0037] Regarding the various arrangements of alternating, unidirectional, and symmetrical layouts, alternating arrangement refers to, for example, the first cutting head 31 is located on the right side of its longitudinal beam 21, and the second cutting head 32 is located on the left side of its longitudinal beam 21, with the two cutting heads facing away from each other; unidirectional arrangement refers to, for example, the first cutting head 31 is located on the right side of its longitudinal beam 21, and the second cutting head 32 is located on the right side of its longitudinal beam 21, with the two cutting heads facing the same direction; symmetrical layout refers to, the first cutting head 31 is located on the left side of its longitudinal beam 21, and the second cutting head 32 is located on the right side of its longitudinal beam 21, with the two being opposite to each other;

[0038] Based on the above explanation of the various arrangements, there are many possible implementations. For example, in the first embodiment, all three cutting heads are located on the right side of their respective longitudinal beams 21. In the second embodiment, the first cutting head 31 is located on the right side of its longitudinal beam 21, and the second cutting head 32 and the third cutting head 33 are located on the left side of their respective longitudinal beams 21. In the third embodiment, the first cutting head 31 and the second cutting head 32 are located on the right side of their respective longitudinal beams 21, and the third cutting head 33 is located on the left side of their respective longitudinal beams 21. In the fourth embodiment, all three cutting heads are located on the left side of their respective longitudinal beams 21. Of course, there can be other embodiments as well. The above are just examples. Depending on the requirements, the arrangement can be freely chosen from alternating arrangements, unidirectional arrangements, and symmetrical layouts.

[0039] In fact, the cutting head is an existing component in the industry. For example, the utility model patent with patent number 202322467017.5 entitled "A Double Blade Head" can also provide the marking function required for cutting leather, and can also mark lines during punching and cutting.

[0040] The drive section has two implementation methods: biased drive motor and mid-mounted drive motor. The mid-mounted drive motor scheme has higher synchronization. The mid-mounted drive motor scheme includes:

[0041] The system includes a motor mounting base a-100, a first drive motor a-101, a first transmission roller a-103, a transmission roller mounting base a-104, a front support plate a-105, a first drive wheel, a first driven wheel, a second driven wheel a-106, a third driven wheel a-107, a rack, and a driven gear a-109. Two front support plates a-105 are provided, each connected to the bottom of both ends of the longitudinal beam 21. A slider 5 is located on the inner surface of the front support plate a-105 and is slidably connected to the first track on the bottom side of the frame 4. A rack is also located on the bottom side of the frame 4. Both the motor mounting base a-100 and the transmission roller mounting base a-104 are disposed on the side of the longitudinal beam 21. At least two transmission roller mounting bases a-104 are provided. The motor mounting base a-100 is located between the two transmission roller mounting bases a-104. The first transmission roller a-103 passes through the two transmission roller mounting bases a-104 and the motor mounting base a-100, and is fixed to the longitudinal beam 21 by the transmission roller mounting bases a-104. The first drive motor a-101 is disposed on the motor mounting base a-100 and corresponds to the middle area of ​​the first transmission roller a-103. The first driven wheel is mounted on the output shaft of the first drive motor a-101, and the first driven wheel and the first driven wheel are driven by a belt. The second driven wheel a-106 is mounted on both ends of the first transmission roller a-103. The third synchronous pulley a-107 is located on the outer surface of the front support plate a-105, and the second driven wheel a-106 and the third driven wheel a-107 are driven by a belt. The driven gear a-109 is located on the inner surface of the front support plate a-105, and the driven gear a-109 and the third driven wheel a-107 are connected by a belt. The shafts are connected, and when the third driven wheel a-107 rotates, it will drive the driven gear a-109 to rotate. The driven gear a-109 meshes with the rack. This design ensures that the instantaneous response of the rotation at both ends of the first transmission roller a-103 is synchronized. As we all know, rigid torsion is the phenomenon of relative rotation between cross sections of an object under the action of torque. Therefore, in order to avoid asynchronous rotation at both ends of the second transmission roller b-100, the solution of using a centrally located motor can solve the lag problem caused by asynchronous rotation at both ends.

[0042] The drive motor bias solution is more economical and easier to assemble, making it suitable for customers with lower precision requirements.

[0043] The main difference between the offset drive motor design and the center-mounted drive motor design lies in their positional relationships. Specifically, the offset drive motor design includes a second transmission roller b-100, a second drive motor b-101, a fourth transmission wheel b-102, and a second drive wheel b-103. The second drive motor b-101 is mounted on the side of one end of the longitudinal beam 21. The fourth transmission wheel b-102 and the second drive wheel b-103 are respectively mounted on the transmission roller mounting seats a-104 at both ends of the longitudinal beam 21. The second transmission roller b-100 is simultaneously driven by both the second drive wheel b-103 and the fourth transmission wheel b-103. The second drive wheel b-102 is fitted onto the first drive wheel, and the second drive wheel b-103 is fitted onto the motor shaft of the second drive motor b-101. Under the action of the second drive motor b-101, the second drive wheel b-103 and the fourth transmission wheel b-102 will also rotate. The second drive wheel b-103 and the fourth transmission wheel b-102 are each fitted with a belt, which drives the third driven wheel a-107 to rotate through the belt. When the third driven wheel a-107 rotates, it will drive the driven gear a-109 to rotate. The driven gear a-109 meshes with the rack, thus ultimately achieving the effect of gear transmission.
