[0036] Please refer to Figure 1 and Figure 2 , the clamping mechanism for solid fuel shaping provided by the embodiments of the present application will be described. The clamping mechanism for solid fuel shaping is installed on the machine tool 100, and the end to be machined of the solid fuel 200 has a clamped part 201 protruding from the circumferential surface of the solid fuel 200; the clamping mechanism comprises a first clamp 300, a second clamp 400, a jaw unit 500, and a feeding adjustment unit 600; the first clamp 300 is fixed at the power end of the machine tool 100; the second clamp 400 is connected with the first clamp 300, so that the clamped part 201 is clamped between the first clamp 300 and the second clamp 400; the jaw unit 500 is used to clamp and support the solid fuel 200; the feeding adjustment unit 600 is used to adjust the position of the jaw unit 500, so that the jaw unit 500 accurately clamps the solid fuel 200 and moves the solid fuel 200 to the power end of the machine tool 100 for fixation.

[0037] Compared with the prior art, in the present application, the end to be machined of the solid fuel 200 is used as the clamped end, which can reduce the influence of the eccentricity of the head and tail of the solid fuel 200 on the machining precision; the clamped part 201 is clamped by the cooperation of the first clamp 300 and the second clamp 400, which can ensure that the solid fuel 200 does not move axially during machining, and the jaw unit 500 assists in supporting from the middle or non-machining area of the solid fuel 200, further improving the stability of clamping. The feeding adjustment unit 600 can adapt to solid fuels 200 of different specifications and shapes by accurately controlling the three-dimensional coordinate position of the jaw unit 500, realize automatic feeding and positioning, and reduce the error caused by manual intervention.

[0038] In an embodiment of the present application, please refer to Figure 2 and Figure 3 , the first clamp 300 is annular, and has a relief hole in the middle for avoiding the machining position on the end of the solid fuel 200 to be machined.

[0039] In this embodiment, the first clamp 300 adopts an annular structure design, and the relief hole in the center can provide sufficient operation space for the machining area of the end to be machined when clamping the solid fuel 200, so as to avoid interference between the clamp and the machining tool or the machining part, and ensure the smooth progress of the machining process. This design not only ensures the stable clamping of the clamped part 201, but also does not affect the normal shaping treatment of the end of the solid fuel 200 to be machined, effectively improving the feasibility and convenience of machining.

[0040] In an embodiment of the present application, please refer to Figure 2 and Figure 3 , the second clamp 400 is annular, and is sleeved on the solid fuel 200, one end of the clamped part 201 abuts against the first clamp 300, and the other end of the clamped part 201 abuts against the second clamp 400.

[0041] In this embodiment, the second clamp 400 and the first clamp 300 form an axial clamping structure, and by abutting against both ends of the clamped part 201 respectively, a uniform axial clamping force can be applied to the clamped part 201 of the solid fuel 200, further limiting the axial displacement of the solid fuel 200 during machining. The annular second clamp 400 also has a relief function, and the inner wall thereof is attached to the outer peripheral surface of the solid fuel 200, which provides stable support while avoiding damage to the non-machining area of the solid fuel 200. Moreover, the cooperation design of the double-annular clamps makes the clamping structure adaptable by adjusting the distance between the first clamp 300 and the second clamp 400 when the clamped part 201 has different lengths, thereby enhancing the versatility and flexibility of the clamping mechanism.

[0042] Specifically, the first clamp 300 and the second clamp 400 can be connected by a plurality of fasteners, and the plurality of fasteners are arranged in a circular array. As shown in Figure 2 , the first clamp 300 is provided with a plurality of first mounting holes 301; the clamped part 201 of the solid fuel 200 is provided with a plurality of second mounting holes 211; and the second clamp 400 is provided with a plurality of third mounting holes 401; the number and position of the first mounting holes 301, the second mounting holes 211 and the third mounting holes 401 correspond one-to-one to the number and position of the fasteners.

[0043] The fastener can be a screw or a bolt; when the fastener is a screw, the first mounting hole 301 and the second mounting hole 211 are through holes, and the third mounting hole 401 is a threaded hole, and the screw is sequentially threaded through the first mounting hole 301, the second mounting hole 211, and is screwed with the third mounting hole 401; when the fastener is a bolt, the first mounting hole 301, the second mounting hole 211, and the third mounting hole 401 are all through holes, and the bolt is sequentially threaded through the first mounting hole 301, the second mounting hole 211, and the third mounting hole 401, and a nut is screwed on the bolt for fixation.

[0044] In an embodiment of the present application, referring to Figure 4 , the clamping jaw unit 500 comprises a clamping jaw mounting plate 501, a clamping jaw driving assembly, and a plurality of clamping jaw assemblies; the clamping jaw mounting plate 501 is connected with the feeding adjustment unit 600; the clamping jaw assemblies are in sliding connection with the clamping jaw mounting plate 501; the plurality of clamping jaw assemblies are arranged at intervals; the clamping jaw driving assembly is connected with the clamping jaw assemblies, and is used to drive the clamping jaw assemblies to move, so as to adjust the interval between adjacent two clamping jaw assemblies.

[0045] In the embodiment, the clamping jaw unit 500 is provided with a plurality of clamping jaw assemblies with adjustable intervals, so that the distance between adjacent clamping jaw assemblies can be flexibly adjusted according to the length and diameter of the solid fuel 200, thereby realizing multi-point support of the solid fuel 200 of different specifications. The clamping jaw mounting plate 501 serves as the mounting base of the clamping jaw assemblies, and after being connected with the feeding adjustment unit 600, can move in position in the three-dimensional space with the feeding adjustment unit 600, so as to ensure that the clamping jaw assemblies can accurately reach the position to be clamped of the solid fuel 200. The clamping jaw driving assembly provides power for the interval adjustment of the clamping jaw assemblies, and when the size of the solid fuel 200 changes, the clamping jaw driving assembly drives the clamping jaw assemblies to slide along the clamping jaw mounting plate 501, so that the plurality of clamping jaw assemblies are uniformly distributed on the outer periphery or the bottom of the solid fuel 200, thereby avoiding the inclination or deformation of the solid fuel 200 during clamping due to uneven distribution of the support points, and effectively improving the stability and reliability of clamping.

[0046] In an embodiment of the present application, referring to Figure 1 and Figure 4 , the clamping jaw driving assembly comprises a driving lead screw 502 and a first lead screw rotation driving member 503; the driving lead screw 502 is in threaded transmission connection with the clamping jaw assemblies; the first lead screw rotation driving member 503 is in transmission connection with the driving lead screw 502, and is used to drive the driving lead screw 502 to rotate.

[0047] In the embodiment, the clamping jaw driving assembly adopts a screw rod transmission mode to realize the distance adjustment of the clamping jaw assembly, and has the characteristics of high transmission precision and stable operation. When the first screw rod rotating driving part 503 is started, the driving end drives the driving screw rod 502 to rotate. Since the driving screw rod 502 and the clamping jaw assembly are in threaded transmission connection, the rotary motion of the screw rod is converted into the linear motion of the clamping jaw assembly along the axial direction of the screw rod. This transmission mode can accurately control the movement distance of the clamping jaw assembly, ensure the accurate adjustment of the distance between the adjacent clamping jaw assemblies, and meet the clamping and supporting requirements of the solid fuel 200 of different sizes. At the same time, the screw rod transmission has a self-locking function, which can reliably maintain the current position after the clamping jaw assembly is adjusted to the position, avoids the change of the distance due to external force, and further ensures the stability of the clamping jaw unit 500.

[0048] In an embodiment of the present application, referring to Figure 4 , the clamping jaw driving assembly further comprises a first belt transmission mechanism 504, the first belt transmission mechanism 504 comprising a first driving wheel, a first transmission belt and a first driven wheel; the first transmission belt being tensioned between the first driving wheel and the first driven wheel, the first driving wheel being installed on the first screw rod rotating driving part 503, and the first driven wheel being installed on the driving screw rod 502.

[0049] In the embodiment, the clamping jaw driving assembly realizes power transmission through a belt transmission mode, and has the advantages of stable transmission and low noise. When the first screw rod rotating driving part 503 operates, the output shaft drives the first driving wheel to rotate synchronously. The first driving wheel transmits power to the first driven wheel through the first transmission belt, and then drives the driving screw rod 502 to rotate. This belt transmission structure can effectively buffer the impact and vibration in the transmission process, reduce the mechanical damage to the driving screw rod 502 and the clamping jaw assembly, and prolong the service life of the device.

[0050] In an embodiment of the present application, referring to Figure 4 , the clamping jaw unit 500 further comprises a first clamping jaw sliding block 505 and a first clamping jaw sliding rail 506; the first clamping jaw sliding block 505 and the first clamping jaw sliding rail 506 are in sliding connection, the first clamping jaw sliding block 505 is installed on the clamping jaw assembly, and the first clamping jaw sliding rail 506 is installed on the clamping jaw mounting plate 501 and is arranged in parallel with the driving screw rod 502.

[0051] In this embodiment, the cooperation between the first clamping jaw sliding block 505 and the first clamping jaw sliding rail 506 provides stable guiding for the movement of the clamping jaw assembly. When the drive screw 502 rotates to drive the clamping jaw assembly to adjust the distance, the first clamping jaw sliding block 505 will slide along the first clamping jaw sliding rail 506 synchronously, ensuring that the clamping jaw assembly always moves smoothly in the preset direction, avoiding deviation or jamming. This sliding guiding structure not only reduces the frictional resistance during the movement of the clamping jaw assembly, improves the flexibility and accuracy of adjustment, but also enables the clamping jaw assembly to maintain good movement stability after long-term use, thereby ensuring the accuracy of clamping and positioning during the shaping process of the solid fuel 200.

[0052] In one embodiment of the present application, referring to Figure 4 , the clamping jaw assembly includes a clamping jaw mounting seat 507, a clamping jaw screw 508, a first clamping jaw arm 509, and a second clamping jaw arm 510; the clamping jaw mounting seat 507 is in sliding connection with the clamping jaw mounting plate 501; the clamping jaw screw 508 is in rotational connection with the clamping jaw mounting seat 507, and the clamping jaw screw 508 has a first threaded section and a second threaded section with opposite rotation directions; the first clamping jaw arm 509 is in threaded transmission connection with the first threaded section; and the second clamping jaw arm 510 is in threaded transmission connection with the second threaded section.

[0053] In this embodiment, the clamping jaw assembly is in sliding cooperation with the clamping jaw mounting plate 501 through the clamping jaw mounting seat 507, providing a basis for the overall position adjustment of the first clamping jaw arm 509 and the second clamping jaw arm 510. When the clamping jaw screw 508 rotates on the clamping jaw mounting seat 507, due to the opposite rotation directions of the first threaded section and the second threaded section, the first clamping jaw arm 509 and the second clamping jaw arm 510 cooperating with the two threaded sections will produce synchronous movement in opposite directions or in the same direction, thereby realizing rapid adjustment of the distance between the clamping jaw arms. This structural design enables the clamping jaw arms to flexibly change the clamping range according to the size of the solid fuel 200, ensuring adaptability to different specifications of solid fuels 200, and ensuring the stability of the clamping state through the self-locking property of threaded transmission, avoiding loosening of the clamping jaw arms due to external forces during the shaping operation, and further improving the reliability and clamping precision of the clamping mechanism.

[0054] In one embodiment of the present application, referring to Figure 4 , the clamping jaw assembly further includes a second clamping jaw sliding block 511 and a second clamping jaw sliding rail 512; the second clamping jaw sliding block 511 and the second clamping jaw sliding rail 512 are in sliding connection, and the second clamping jaw sliding block 511 is provided with two, respectively installed on the first clamping jaw arm 509 and the second clamping jaw arm 510, and the second clamping jaw sliding rail 512 is installed on the jaw mounting seat and is arranged in parallel with the clamping jaw screw 508.

[0055] In the embodiment, the cooperation of the second clamping jaw sliding blocks 511 and the second clamping jaw sliding rails 512 provides a guiding effect for the movement of the first clamping jaw arm 509 and the second clamping jaw arm 510. When the clamping jaw lead screw 508 drives the first clamping jaw arm 509 and the second clamping jaw arm 510 to move towards or away from each other, the two second clamping jaw sliding blocks 511 will slide smoothly along the second clamping jaw sliding rails 512, thereby effectively avoiding the phenomenon of deviation or jamming of the clamping jaw arms during movement. This guiding structure, in combination with threaded transmission, further improves the precision and smoothness of the movement of the clamping jaw arms, ensures that the clamping jaw assembly can maintain a stable movement trajectory during the clamping operation of the solid fuel 200, and helps to improve the working efficiency of the overall clamping mechanism and the quality of the shaping operation.

[0056] In an embodiment of the present application, referring to Figure 4 , the clamping jaw assembly further comprises a second lead screw rotary driving member 513, which is in transmission connection with the clamping jaw lead screw 508, and is used to drive the clamping jaw lead screw 508 to rotate.

[0057] In the embodiment, the second lead screw rotary driving member 513 provides a power source for the rotation of the clamping jaw lead screw 508. Through the transmission connection with the clamping jaw lead screw 508, it can accurately control the rotation direction and speed of the lead screw. When it is necessary to adjust the distance between the clamping jaw arms, the second lead screw rotary driving member 513 is started to drive the clamping jaw lead screw 508 to rotate in a predetermined direction, thereby enabling the first clamping jaw arm 509 and the second clamping jaw arm 510 to automatically move towards or away from each other, effectively replacing the traditional manual adjustment mode, and greatly improving the convenience and efficiency of operation. At the same time, the second lead screw rotary driving member 513 can select different driving types according to actual working condition requirements, such as servo motor or stepper motor, etc., to meet different control requirements for the movement speed and position accuracy of the clamping jaw arms, further enhancing the adaptability and intelligent level of the clamping jaw assembly during the shaping and clamping process of the solid fuel 200.

[0058] In an embodiment of the present application, referring to Figure 4 , the clamping jaw assembly further comprises a second belt transmission mechanism 514, which comprises a second driving wheel, a second transmission belt and a second driven wheel; the second transmission belt is tensioned between the second driving wheel and the second driven wheel, the second driving wheel is installed on the second lead screw rotary driving member 513, and the second driven wheel is installed on the clamping jaw lead screw 508.

[0059] In this embodiment, the second driving wheel is fixedly connected with the output shaft of the second screw rotation driving member 513. When the second screw rotation driving member 513 is started, the output shaft drives the second driving wheel to rotate synchronously. The second driving wheel transmits power to the second driven wheel through the second transmission belt, thereby driving the jaw screw 508 to rotate. This belt transmission structure has the characteristics of stable transmission and low noise, which can effectively reduce the impact and vibration in the power transmission process and ensure the stability of the jaw arm movement. At the same time, the elastic properties of the transmission belt can also buffer the overload to a certain extent, thereby protecting the second screw rotation driving member 513 and the jaw screw 508.

[0060] In an embodiment of the present application, the first clamp 300 is an aluminum clamp or a plastic clamp; and the second clamp 400 is an aluminum clamp or a plastic clamp.

[0061] In this embodiment, the aluminum clamp or the plastic clamp is used as the first clamp 300 and the second clamp 400, which can reduce the indentation or scratch on the solid fuel 200, and is especially suitable for the solid fuel 200 with low surface hardness. The aluminum material has the characteristics of light weight, high strength and corrosion resistance, which can reduce the overall weight of the clamping mechanism while ensuring the clamping force, thereby reducing the load of the power end of the machine tool 100. The plastic clamp has better elasticity and insulation, which can buffer the clamping force through its own deformation in the clamping process, thereby avoiding damage to the fuel surface caused by rigid contact, preventing safety hazards caused by static electricity in the machining process, and further improving the safety and applicability of the clamping mechanism.

[0062] In an embodiment of the present application, the first jaw arm 509 is an aluminum jaw arm or a plastic jaw arm; and the second jaw arm 510 is an aluminum jaw arm or a plastic jaw arm.

[0063] In this embodiment, the aluminum jaw arm or the plastic jaw arm can effectively avoid damage to the surface of the solid fuel 200 when clamping the solid fuel 200, and is especially suitable for the solid fuel 200 with a surface that is easy to break or has high cleanliness requirements. The aluminum jaw arm not only has good structural strength and wear resistance, but also can ensure long-term stable clamping. Moreover, the lightweight characteristics of the aluminum jaw arm can help to reduce the motion inertia of the jaw unit 500 and improve the response speed of the clamping adjustment. The plastic jaw arm has better anti-skid performance and buffering effect, which can increase the friction force through flexible contact with the surface of the solid fuel 200 to prevent slipping during clamping. Moreover, when the clamping force is too large, the plastic jaw arm can release stress through slight deformation to avoid cracks or indentations on the surface of the fuel, thereby further protecting the integrity of the solid fuel 200.

[0064] In an embodiment of the present application, please refer to Figure 5 and Figure 6The feeding adjustment unit 600 comprises a rack 601, a first feeding sliding piece 602, a second feeding sliding piece 603 and a third feeding sliding piece 604. The first feeding sliding piece 602 is in sliding connection with the rack 601 and can move along the X direction. The second feeding sliding piece 603 is in sliding connection with the first feeding sliding piece 602 and can move along the Z direction. The third feeding sliding piece 604 is in sliding connection with the second feeding sliding piece 603 and can move along the Y direction. The clamping jaw unit is installed on the third feeding sliding piece 604.

[0065] In the embodiment, the feeding adjustment unit 600 realizes the three-dimensional space adjustment of the clamping jaw assembly in the X, Y and Z directions through the multi-layer sliding connection structure, so as to meet the clamping requirements of the solid fuel 200 of different specifications and different placement positions. The rack 601 serves as the installation basis of the whole feeding adjustment unit 600 and provides stable support for each sliding piece. The movement of the first feeding sliding piece 602 along the X direction can realize the horizontal transverse position adjustment of the clamping jaw assembly, so that the clamping jaw can be aligned with the transverse clamping point of the solid fuel 200. The movement of the second feeding sliding piece 603 along the Z direction is used for adjusting the height of the clamping jaw assembly to adapt to the solid fuel 200 or the clamping station of different heights. The movement of the third feeding sliding piece 604 along the Y direction further realizes the horizontal longitudinal position adjustment of the clamping jaw assembly, which can be combined with the movement along the X direction to accurately position the clamping jaw to the longitudinal clamping position of the solid fuel 200. The multi-layer and multi-direction sliding adjustment structure makes the movement trajectory of the clamping jaw assembly more flexible and variable, can quickly respond to the clamping position requirements of different solid fuels 200, effectively improves the universality and adjustment accuracy of the clamping mechanism, and ensures that the clamping positioning can be accurately and stably completed before the solid fuel 200 is shaped and processed.

[0066] In an embodiment of the present application, referring to Figure 6 The feeding adjustment unit 600 further comprises a first feeding driving piece 605, a gear 606 and a rack 607. The first feeding driving piece 605 is installed on the first feeding sliding piece 602. The gear 606 is installed on the driving end of the first feeding driving piece 605. The rack 607 is installed on the rack 601 and is arranged along the X direction. The rack 607 is in engagement with the gear 606.

[0067] In this embodiment, when the first feed drive member 605 is in operation, its driving end drives the gear 606 to rotate. Since the gear 606 meshes with the rack 607 fixed to the frame 601, the rotational motion of the gear 606 is converted into linear movement of the first feed slide 602 along the X-direction. This gear 606 and rack 607 transmission method features high transmission precision and fast response speed, ensuring smoother and more accurate movement of the first feed slide 602 in the X-direction. This further improves the accuracy of the horizontal position adjustment of the clamping jaw assembly and provides reliable power and transmission for the subsequent precise clamping of the solid fuel 200. Furthermore, the meshing transmission structure of the gear 606 and rack 607 is simple and compact, making it easy to install and maintain. It maintains stable transmission performance during long-term use, reduces adjustment errors caused by wear or loosening of transmission components, and extends the service life of the feed adjustment unit 600.

[0068] In one embodiment of the present application, see Figure 7 The feeding adjustment unit 600 also includes a second feeding drive 608, a feeding screw 609 and a feeding nut 610. The second feeding drive 608 is installed on the first feeding slide 602. The driving end of the second feeding drive 608 is connected to the feeding screw 609. The feeding nut 610 is threadedly connected to the feeding screw 609. The feeding nut 610 is installed on the second feeding slide 603.

[0069] In this embodiment, the feed adjustment unit 600 achieves movement of the second feed slide 603 along the Z direction through the cooperation of the second feed drive 608, the feed screw 609, and the feed nut 610. When the second feed drive 608 is activated, its driving end drives the feed screw 609 to rotate, and the feed nut 610, under the action of the screw thread, generates linear motion along the screw axis. Since the feed nut 610 is fixedly connected to the second feed slide 603, it drives the second feed slide 603 to move synchronously along the Z direction. The screw-nut transmission has the advantages of high transmission accuracy and good self-locking performance. It can accurately control the lifting height of the second feed slide 603 and ensure the positioning accuracy of the clamping jaw assembly in the Z direction. At the same time, this transmission method operates smoothly and noiselessly, effectively reducing clamping errors caused by improper height adjustment, and providing reliable protection for the vertical position adjustment of the solid fuel 200 during the shaping process.

[0070] In one embodiment of the present application, see Figure 6 The feeding adjustment unit 600 also includes a first feeding slide rail 611 and a first feeding slider 612. The first feeding slide rail 611 is installed on the frame 601, and the first feeding slider 612 is installed on the first feeding slide 602. The first feeding slider 612 and the first feeding slide rail 611 are slidably connected.

[0071] In this embodiment, the sliding cooperation between the first feeding sliding rail 611 and the first feeding sliding block 612 provides guiding support for the movement of the first feeding sliding member 602 along the X direction. When the first feeding driving member 605 drives the first feeding sliding member 602 to move through the gear 606 and the rack 607, the first feeding sliding block 612 will slide along the first feeding sliding rail 611 synchronously, ensuring that the first feeding sliding member 602 always maintains the preset movement trajectory and avoiding deviation or shaking. This sliding rail and sliding block structure can effectively reduce the frictional resistance during the movement of the first feeding sliding member 602, improving the stability and smoothness of movement.

[0072] In one embodiment of the present application, please refer to Figure 7 The feeding adjustment unit 600 further comprises a second feeding sliding rail 613 and a second feeding sliding block 614. The second feeding sliding rail 613 is installed on the first feeding sliding member 602, and the second feeding sliding block 614 is installed on the second feeding sliding member 603. The second feeding sliding block 614 and the second feeding sliding rail 613 are in sliding connection.

[0073] In this embodiment, the sliding cooperation between the second feeding sliding rail 613 and the second feeding sliding block 614 provides stable guidance for the movement of the second feeding sliding member 603 along the Z direction. When the second feeding driving member 608 drives the second feeding sliding member 603 to move up and down through the feeding lead screw 609 and the feeding nut 610, the second feeding sliding block 614 will slide along the second feeding sliding rail 613 synchronously, ensuring that the movement trajectory of the second feeding sliding member 603 in the vertical direction is accurate and avoiding deviation due to gravity or external force. This guiding structure not only reduces the friction coefficient during the movement of the second feeding sliding member 603, improving the flexibility and response speed of height adjustment, but also disperses the load during transmission, reducing the stress concentration of the feeding lead screw 609 and the feeding nut 610, further prolonging the overall service life of the feeding adjustment unit 600 and ensuring the accuracy and reliability of the positioning of the clamping jaw assembly in the Z direction.

[0074] Specifically, in order to facilitate assembly and maintenance, please refer to Figure 7 The first feeding sliding member 602 is provided with a fixing seat 621; the second feeding driving member 608 and the second feeding sliding rail 613 are arranged on the fixing seat 621; and the fixing seat 621 is detachably connected with the first feeding sliding member 602 through bolts. This modular design makes the installation, replacement and maintenance of the second feeding driving member 608 and the second feeding sliding rail 613 more convenient. When the second feeding driving member 608 needs to be repaired or replaced, the fixing seat 621 together with the components thereon can be disassembled integrally by loosening the connecting bolts between the fixing seat 621 and the first feeding sliding member 602, without the need to disassemble other structures of the feeding adjustment unit 600 on a large scale, effectively shortening the maintenance time and reducing the maintenance difficulty.

[0075] In an embodiment of the present application, the sliding connection structure of the third feeding sliding member 604 and the second feeding sliding member 603 can refer to the sliding connection structure of the second feeding sliding member 603 and the first feeding sliding member 602, that is, the movement along the Y direction is realized by setting the third feeding driving member, the third feeding screw rod, the third feeding nut, the third feeding sliding rail and the third feeding sliding block. The third feeding driving member is a power source, which drives the third feeding screw rod to rotate, and then drives the third feeding sliding member connected with the third feeding nut to move along the Y direction; the third feeding sliding rail and the third feeding sliding block provide guidance and support for the movement, ensuring the stability and precision of the movement.

[0076] In an embodiment of the present application, please refer to Figure 1 The clamping mechanism further comprises a feeding trolley 700, which is used to transport the solid fuel 200 to the lower side of the jaw unit 500.

[0077] In the embodiment, the feeding trolley 700 serves as a carrying device for the solid fuel 200, and can realize the automatic transfer of the solid fuel 200 from the storage area to the working area of the jaw unit 500. The bottom of the feeding trolley 700 is usually provided with universal wheels or directional wheels, and is equipped with a braking device, which can be quickly locked after reaching the designated position, ensuring the stability and positioning accuracy during transportation. The table surface of the feeding trolley 700 can be designed as a flat surface, a V-shaped surface or an arc-shaped surface according to the shape and size of the solid fuel 200, so as to adapt to the placement requirements of different types of fuels and prevent the fuel from rolling or toppling during transportation. At the same time, the feeding trolley 700 can also be provided with a positioning sensor or a guiding mechanism, which cooperates with the control system of the jaw unit 500 to realize the precise docking of the feeding trolley 700 and the jaw unit 500, so as to ensure that the solid fuel 200 can be accurately placed within the clamping range of the jaw assembly, effectively reducing manual intervention and improving the automation degree and production efficiency of the solid fuel 200 shaping operation.

[0078] The working process of the clamping mechanism for solid fuel shaping provided in the embodiment of the present application is as follows:

[0079] Place the solid fuel 200 to be shaped on the table surface of the feeding trolley 700, and transport it to the lower side of the jaw unit 500 through the movement of the feeding trolley 700.

[0080] Install the first clamp 300 and the second clamp 400 on the clamped part 201 of the solid fuel 200;

[0081] Start the feeding adjustment unit 600 to accurately position the jaw unit 500 to the clamped position of the solid fuel 200.

[0082] Start the jaw unit 500 to clamp the solid fuel 200 by the first jaw arm 509 and the second jaw arm 510;

[0083] Again start the feeding adjustment unit 600, the solid fuel 200 is transferred to the power end of the machine tool 100, and then the first clamp 300 is fixed on the power end of the machine tool 100, so as to complete the clamping of the solid fuel 200.

[0084] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
