Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically a heavy-duty logistics warehouse inlet stacker crane. Background Technology

[0002] Heavy-duty warehouses are storage devices used for heavy goods or materials and are widely used in logistics and engineering fields.

[0003] When storing large sheet metal goods or materials in heavy-duty warehouses, there are generally two methods for transporting large sheet metal to the heavy-duty warehouses:

[0004] Firstly, the transfer mechanism transports large plates to the entrance of the heavy-duty compartment, and pushes the large plates on the transfer mechanism into the interior of the heavy-duty compartment through the pushing structure.

[0005] Secondly, unlike the methods described above, the transfer mechanism transports large plates to the entrance of the heavy-duty compartment, where they are then gripped by a gripping structure, which takes over the transfer function from the transfer mechanism. Specifically, as described in the text of Chinese Patent Publication No. CN105314397A entitled "A Plate Gripping and Positioning Feeding Device," a vacuum suction cup is used to grip the plates, and they are then positioned and transported to a designated location via a track.

[0006] In the first method described above, the transfer mechanism needs to stop and wait for the large sheet metal to be transported to the heavy-duty bin, making it impossible to quickly perform the next transfer operation after the transfer mechanism is in place, which obviously affects the overall efficiency of the production line. In the second method, although the transfer mechanism does not need to stop and wait for the large sheet metal to be transported to the heavy-duty bin, thus improving the overall efficiency of the production line, the movement of the gripping structure after gripping the large sheet metal to the designated position often involves multi-axis linkage, resulting in a high failure rate and significantly increased costs. Furthermore, for heavy-duty bins with multiple storage layers, the narrow gaps between the sheet metal prevent the gripping structure from directly delivering large sheet metal to the heavy-duty bin, thus requiring an additional transfer structure, which obviously further increases costs. Therefore, this issue urgently needs to be addressed. Utility Model Content

[0007] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a heavy-duty logistics warehouse imported stacker crane, which has the advantages of low failure rate and low cost while ensuring the overall efficiency of the production line.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A heavy-duty logistics warehouse import stacker crane includes an import support frame with an import lifting frame sliding on it. The import lifting frame is driven by an import hoisting mechanism to perform vertical lifting and lowering actions. The lower part of the import lifting frame is located on both sides of the plate feeding direction, and a gripping frame is hinged to the import swing seat via an import swing seat. The hinge axis of the import swing seat is arranged along the plate feeding direction. The gripping frames are driven by a gripping power mechanism to form a gripping state where they are close to each other and a releasing state where they are separated from each other. The lower part of the import lifting frame is rotatably fitted with an import support guide wheel. In the gripping state, the rotation axis of the import support guide wheel is horizontal and perpendicular to the plate feeding direction. The import support guide wheels on each side of the import lifting frame are arranged at least two horizontally spaced along the plate feeding direction. The outer top side of the outer edge of all the import support guide wheels in the gripping state forms a feeding platform for plate feeding.

[0010] As a further embodiment of this utility model: the gripping frame is equipped with an imported drive wheel that is driven to rotate by an imported drive motor, and the rotation axis of the imported drive wheel is parallel to the rotation axis of the imported support guide wheel; both the imported drive motor and the imported drive wheel are mounted on an imported support platform, and the imported support platform is elastically and movably connected to the gripping frame, so that the outer edge of the imported drive wheel can generate an elastic squeezing action to elastically squeeze the plate on the feeding platform.

[0011] As a further embodiment of this utility model: one end of the inlet support platform is hinged to the gripping frame, and the hinge axis of the inlet support platform is parallel to the rotation axis of the inlet drive wheel. In the non-working state, the inlet support platform is driven by an elastic element, causing the outer edge of the inlet drive wheel to protrude above the feeding platform. At this time, the extension direction of the cantilever end of the inlet support platform is distributed in the feeding direction of the plate.

[0012] As a further embodiment of this utility model: an import pad block fixedly connected to the top of the import support platform and fixed to the gripping frame is provided; an import guide screw penetrating the import pad block is swayingly connected to the upper part of the import support platform; the swing axis of the import guide screw is parallel to the rotation axis of the import drive wheel; an elongated hole for the import guide screw to pass through is provided on the import pad block, and the length direction of the elongated hole is parallel to the feeding direction of the plate; an import spring and an import lower nut are respectively fitted on the rod body located above and below the import pad block on the import guide screw.

[0013] As a further improvement of this utility model, an inlet nut is also threaded onto the rod body located above the inlet spring on the inlet guide screw.

[0014] As a further embodiment of this utility model: the gripping power mechanism includes a gripping motor installed in the middle of the inlet lifting frame, the output shaft of the gripping motor is arranged horizontally along the feeding direction of the plate, the inlet swing seat is located on the inner side wall of the gripping frame, and the output shaft of the gripping motor is connected to the top of the gripping frames on both sides through two sets of crank connecting rods respectively.

[0015] As a further improvement of this utility model, the gripping frames on both sides are each configured as at least two arranged at intervals along the feeding direction of the sheet material.

[0016] As a further improvement of this utility model: a guide assembly is arranged at the outlet of the feeding platform. The guide assembly includes a connecting frame connected to the inlet lifting frame. The connecting frame is equipped with auxiliary wheels for supporting the lower part of the plate and correction wheels for positioning the sides of the plate.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The imported stacker crane uses its gripping frame to grab the sheet metal onto the feeding platform. Then, the imported lifting frame moves upward to lift the sheet metal off the transfer trolley. The transfer trolley in the transfer mechanism can then transfer the sheet metal again, effectively ensuring the efficiency of the production line storage.

[0019] In addition, the gripper is integrated with a feeding platform consisting of imported support guide wheels. Utilizing the low resistance of the feeding platform, the sheet metal can be transported into the bin by either self-rotating feeding through the imported support guide wheels or by setting up a separate conveying structure on the imported stacker crane. This eliminates the need for the gripper to transfer the sheet metal to other transfer platforms. In addition to ensuring the overall efficiency of the production line, it also has the advantages of low failure rate and low cost.

[0020] 2. The imported drive wheel in the imported stacker crane also adopts a drive method that elastically presses the bottom of the plate, creating sufficient friction between the imported drive wheel and the plate. This ensures stable contact between the imported drive wheel and the bottom of the plate even when there is wear on the outer surface of the imported drive wheel. This structural arrangement not only provides stable driving for the plate but also has the advantages of a large transmission stroke and a small footprint.

[0021] 3. The imported springs that apply elastic force to the imported drive wheel have an adjustable structure in both the initial elastic force in the non-working state and the working elastic force in the working state, in order to adapt to the conveying of plates of different weights and to compensate for the loss of elastic force after fatigue damage to the imported springs.

[0022] 4. By rotating the output shaft of the gripping motor, two sets of crank connecting rods drive the gripping frames on both sides to rotate synchronously, thereby forming gripping and releasing states respectively, effectively ensuring the synchronicity of the rotation of the gripping frames on both sides.

[0023] 5. To prevent the sheet material from tipping over when it is conveyed to the gap between the feed platform outlet and the silo, a guide assembly is installed at the feed platform outlet. During the feeding process, auxiliary wheels are used to support the lower part of the sheet material at the feed platform outlet, which can prevent the sheet material from tipping over. At the same time, the setting of the correction wheels can also position the sides of the sheet material to ensure that the sheet material is accurately conveyed into the silo.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0042] This utility model is one of the components in a heavy-duty silo production line. The following description of this utility model will be combined with the heavy-duty silo production line to illustrate its content. The specific structure of the heavy-duty silo production line is shown below. Figure 1-15As shown, its main structure includes a heavy-duty silo body 30, an inlet stacker crane 10 for feeding material into the plate inlet of the silo body 30, and an outlet retrieving machine 40 for discharging material from the plate outlet of the silo body 30. The following describes the silo body 30, the inlet stacker crane 10, and the outlet retrieving machine 40 in detail.

[0043] 1. Warehouse body 30

[0044] like Figure 12 As shown, the storage unit 30 includes a support frame 32. The inner side of the support frame 32 forms a storage channel for storing sheet metal. The two ends of the storage channel constitute the sheet metal's outlet and inlet, respectively. The inner side of the storage channel is fitted with storage rollers 33 whose rotation axis is horizontal and perpendicular to the length of the storage channel. Several storage rollers 33 are arranged at intervals along the length of the storage channel, and the outer edges of all the storage rollers 33 together form a sheet metal storage platform. Low-resistance conveying of the sheet metal is achieved by utilizing the rolling motion of the sheet metal on the storage platform.

[0045] Specifically, such as Figure 14 and 15 As shown, storage power components 35 are arranged at the intervals of storage rollers 33. Storage power components 35 include storage power rollers 354 driven by storage power motors 351, with their rotation axes parallel to the rotation axes of the storage rollers 33. Storage power components 35 are elastically and movably connected to the inner side of the storage channel, allowing the outer edge of the storage power rollers 354 to elastically compress the plates on the storage platform. In actual implementation, the outer surface of the storage power rollers 354 can be made of high-damping materials such as rubber or silicone. The elastic compression of the plates on the storage platform by the storage power rollers 354 creates sufficient friction between them, ensuring stable contact between the storage power rollers 354 and the bottom of the plates even when the outer surface of the storage power rollers 354 is worn. At this time, driving the storage power rollers 354 to rotate via the storage power motors 351 drives the plates to move on the conveying platform.

[0046] Of course, the aforementioned storage roller 33 can also adopt a transmission structure that uses a direct-drive motor or a chain-connected motor to form a self-rotating mechanism, with the storage roller 33 rotating on its own to drive the plate to move on the storage platform. However, due to issues with installation and manufacturing accuracy, this self-rotating drive method of the storage roller 33 makes it difficult to ensure that the top edge of the storage roller 33 is precisely on the same horizontal line. This results in an uncontrollable number of contacts between the storage roller 33 and the plate during movement, leading to an uncontrollable problem of transmission power to the plate.

[0047] Furthermore, such as Figure 15As shown, the storage power assembly 35 also includes a turntable 352 with one end hinged to the support frame 32, and the hinge axis of the turntable 352 is parallel to the rotation axis of the storage roller 33. The storage power roller 354 and the storage power motor 351 are both mounted on the turntable 352. In the idle state when not storing, the turntable 352 is driven by an elastic element, causing the top edge of the storage power roller 354 to protrude above the storage platform. At this time, the cantilever end of the turntable 352 extends in the direction of feeding the plate, which allows the plate to press the turntable 352 downward with low resistance when it moves along the feeding direction and squeezes the storage power roller 354. Compared with driving the turntable 352 to move up and down by an elastic telescopic rod, there is less risk of transmission dead points.

[0048] Furthermore, the elastic drive source for the rotation of turntable 352 can come from a torsion spring installed at the pivot of turntable 352. Alternatively, as... Figure 15 As shown, a support base 321, which is fixed to the support frame 32, is fixedly connected directly below the turntable 352. A support screw 355, which passes through the support base 321, is sway-connected to the lower part of the turntable 352. The swaying axis of the support screw 355 is parallel to the rotation axis of the storage roller 33. An elongated hole for the support screw 355 to pass through is provided on the support base 321, and the length direction of the elongated hole is parallel to the length direction of the storage channel. The arrangement of the elongated hole ensures that when the support screw 355 rotates with the turntable 352, the support base 321 has a function to avoid the support screw. The space for the rod 355 to move; the rod body above and below the support seat 321 on the support screw 355 is respectively equipped with an assist spring 353 and a positioning nut 357. The assist spring 353 applies the elastic force of the turntable 352 to rotate, and the positioning nut 357 can be used to locate the limit position of the upward sliding of the support screw 355. Thus, the position of the storage power roller 354 in the idle state and the initial elastic force of the assist spring 353 in the idle state can be finally located to ensure that the plate can stably press down the storage power roller 354.

[0049] In addition, such as Figure 15 As shown, a spring adjustment nut 356 is threaded onto the rod body of the support screw 355, located above the assist spring 353. By setting the spring adjustment nut 356, the initial spring force of the assist spring 353 in the idle state can be adjusted when the initial position of the storage power roller 354 remains unchanged, and the working spring force of the assist spring 353 in the working state can also be adjusted. This ensures that under the action of the spring force of the assist spring 353, the storage power roller 354 has sufficient friction with the bottom of the plate and will not push the plate upward and flip.

[0050] Based on the above, each layer of storage rollers 33 can be configured as elongated storage rollers 33, with both ends of the storage rollers 33 rotating and engaging with the sides of the storage channel, respectively. Alternatively, as shown... Figure 12-14 As shown, each layer of storage rollers 33 is arranged in two rows symmetrically distributed on both sides of the storage channel. Although this arrangement is also a cantilever structure, the lever arm of each storage roller 33 is small when subjected to force, which saves costs and ensures that the rotation axis of the storage roller 33 is not easily damaged.

[0051] Furthermore, in actual implementation, the storage power components 35 can be arranged at the intervals between each storage roller 33, or they can be arranged in a random, interspersed manner according to actual needs. Of course, preferably, such as... Figure 12 As shown, storage power components 35 are arranged at the intervals between the two rows of storage rollers 33. From a horizontal perspective perpendicular to the storage channel, the storage power components 35 are arranged alternately at the intervals between the two rows of storage rollers 33. This ensures that the intervals between adjacent storage power components 35 are reduced while the number of storage power components 35 is reduced. In other words, it ensures stable power transmission to the plate during the movement of the storage platform, while reducing the cost of the device.

[0052] The sheet metal stored in the 30mm bin has specific requirements regarding the storage environment, such as... Figure 11 As shown, the outer wall of the support frame 32 is equipped with an insulation board 31, and roller shutters are installed at both ends of the storage channel, ensuring that the silo 30 has relatively good insulation and dustproof and waterproof performance.

[0053] In actual implementation, to prevent the sheet material from slipping directly from the sheet material outlet during storage in the conveying channel, a limit component 34 is installed at the outlet of the storage channel. Specifically, such as... Figure 13 As shown, the storage channel is divided into at least two material channels by at least two layers of storage rollers 33. The limiting component 34 includes baffles 341 arranged at the outlets of at least two parallel material channels. The baffles 341 are rotatably fitted at the material channels, and the rotation axis of the baffles 341 is parallel to the direction of movement of the plate at the material channel outlet, so that the baffles 341 can be in an open state that avoids the material channel outlet and in a blocking state that intersects with the storage channel outlet during rotation. In addition, a connecting rod 342 is hinged between adjacent baffles 341, and the hinge axis of the connecting rod 342 is parallel to the rotation axis of the baffles 341. This not only enables the multiple baffles 341 to rotate synchronously, but also makes the multiple baffles 341 form a mutually auxiliary whole, thereby ensuring that the baffles 341 can stably block the large mass plate.

[0054] Furthermore, such as Figure 13As shown, one end of an electric telescopic rod 343 is hinged at the outlet of the material channel, and the other end of the electric telescopic rod 343 is hinged to any baffle 341. Both hinge axes of the electric telescopic rod 343 are parallel to the rotation axis of the baffle 341, so that when the electric telescopic rod 343 performs telescopic action, it drives the baffle 341 to perform a rotation process, thereby realizing the automatic switching between the open state and the blocking state of multiple baffles 341.

[0055] 2. Imported stacker crane 10

[0056] like Figure 1-5 As shown, the imported stacker crane 10 includes an imported support 11. An imported lifting frame 13, driven by an imported hoisting mechanism 12, slides on the imported support 11 to perform vertical lifting actions. On both sides of the lower part of the imported lifting frame 13, in the plate feeding direction, gripping frames 14 are hinged via imported swing seats 141. The hinge axis of the imported swing seats 141 is arranged along the plate feeding direction. The gripping frames 14 are driven by a gripping power mechanism 15 to form a gripping state where they are close to each other and a releasing state where they are separated. The lower part of the imported lifting frame 13 is rotatably fitted with imported support guide wheels 142. In the gripping state, the rotation axis of the imported support guide wheels 142 is horizontal and perpendicular to the plate feeding direction. At least two imported support guide wheels 142 on each side of the imported lifting frame 13 are arranged horizontally at intervals along the plate feeding direction. The outer top edges of all the imported support guide wheels 142 in the gripping state form the plate feeding platform.

[0057] The gripping power mechanism 15 is initially in the released state. During operation, the material is first transported to the area directly below the feeding platform via the transfer trolley in the transfer mechanism 20. At this time, the imported lifting mechanism 12 drives the imported lifting frame 13 to move downwards as a whole. Simultaneously, the gripping frames 14 on the imported lifting frame 13 approach each other under the drive of the gripping power mechanism 15 to form a gripping state, thereby gripping the sheet material onto the feeding platform. Then, the imported lifting frame 13 moves upwards again, lifting the sheet material off the transfer trolley. The transfer trolley in the transfer mechanism 20 can then transfer the sheet material again, effectively ensuring the efficiency of the production line storage. When the imported lifting frame 13 lifts the sheet material to the storage platform of the corresponding height in the bin 30, the imported support guide wheel 142 can be driven by a motor to rotate on its own, or the sheet material can be pushed into the bin 30 by other pushing structures installed on the imported lifting frame 13 or by manual pushing.

[0058] Based on the above, such as Figure 5As shown, in this application, a roller drive structure is used to drive the plate material to move from the feeding platform to the storage platform. Specifically, an imported drive wheel 145 driven by an imported drive motor 144 is installed on the gripping frame 14. The rotation axis of the imported drive wheel 145 is parallel to the rotation axis of the imported support guide wheel 142. Both the imported drive motor 144 and the imported drive wheel 145 are mounted on an imported support platform 143, which is elastically connected to the gripping frame 14. This allows the outer edge of the imported drive wheel 145 to elastically press against the plate material on the feeding platform. Similar to the storage power assembly 35 in the hopper 30, the elastic pressing of the bottom of the plate material by the imported drive wheel 145 creates sufficient friction between the imported drive wheel 145 and the plate material, ensuring stable contact between the imported drive wheel 145 and the bottom of the plate material even when there is wear on the outer surface of the imported drive wheel 145. At this time, the plate material can be driven to move on the feeding platform by rotating the imported drive wheel 145.

[0059] Furthermore, such as Figure 5 As shown, one end of the inlet support platform 143 is hinged to the gripping frame 14, and the hinge axis of the inlet support platform 143 is parallel to the rotation axis of the inlet drive wheel 145. In the non-working state, the inlet support platform 143 is driven by an elastic element, causing the top edge of the inlet drive wheel 145 to protrude above the feeding platform. At this time, the cantilever end of the inlet support platform 143 extends in the direction of the plate feeding. Similar to the storage power assembly 35 in the hopper 30, this allows the plate to press the inlet support platform 143 downwards with low resistance when it moves along the feeding direction and squeezes the inlet drive wheel 145. Compared to driving the inlet support platform 143 to move up and down via an elastic telescopic rod, there is less risk of transmission dead points.

[0060] Furthermore, such as Figure 5 As shown, an import pad 148, which is fixed to the gripper frame 14, is fixedly connected directly above the import support platform 143. An import guide screw 146, which passes through the import pad 148, is swayingly connected to the upper part of the import support platform 143. The swing axis of the import guide screw 146 is parallel to the rotation axis of the import drive wheel 145. An elongated hole for the import guide screw 146 to pass through is provided on the import pad 148, and the length direction of the elongated hole is parallel to the feeding direction of the plate. An import spring 147 and an import lower nut 1462 are respectively fitted on the rod body above and below the import pad 148 on the import guide screw 146. An import upper nut 1461 is also threadedly screwed onto the rod body above the import spring 147 on the import guide screw 146. Similar to the storage power assembly 35 inside the compartment 30, it can realize the positioning of the imported drive wheel 145 and the initial elastic force adjustment of the imported spring 147 in the non-working state. At the same time, it can also realize the elastic force adjustment of the imported spring 147 in the working state.

[0061] Based on the above, such as Figure 3 As shown, the gripping power mechanism 15 includes a gripping motor 151 installed in the middle of the inlet lifting frame 13. The output shaft of the gripping motor 151 is arranged horizontally along the feeding direction of the plate. The inlet swing seat 141 is located on the inner side wall of the gripping frame 14. The output shaft of the gripping motor 151 is connected to the top of the gripping frames 14 on both sides through two sets of crank connecting rods 152. In use, the output shaft of the gripping motor 151 rotates, driving the two sets of crank connecting rods 152 to drive the gripping frames 14 on both sides to rotate synchronously, so as to form a gripping state and a release state respectively, effectively ensuring the synchronicity of the rotation of the gripping frames 14 on both sides.

[0062] Furthermore, such as Figure 3 As shown, at least two gripping frames 14 are arranged at intervals along the feeding direction of the sheet material on both sides. By distributing the weight of the sheet material among multiple gripping frames 14, the service life of the gripping frames 14 is effectively improved.

[0063] Based on the above, since the gripper 14 swings, if the outlet of the feeding platform is flush with the end of the inlet support 11 near the hopper 30, a gap must be reserved at the column of the inlet support 11 for the gripper 14 to swing, increasing the installation area of ​​the device. Therefore, there will be a certain gap between the outlet of the feeding platform and the hopper 30. Figure 4 As shown, to prevent the sheet material from tipping over when it is conveyed to the gap between the outlet of the feeding platform and the silo 30, a guide assembly is arranged at the outlet of the feeding platform. The guide assembly includes a connecting frame 163 connected to the inlet lifting frame 13. The connecting frame 163 is equipped with auxiliary wheels 162 for supporting the lower part of the sheet material and straightening wheels 161 for positioning the sides of the sheet material. The auxiliary wheels 162 support the lower part of the sheet material to prevent it from tipping over. At the same time, the straightening wheels 161 can also position the sides of the sheet material to ensure that the sheet material is accurately conveyed into the silo 30.

[0064] 3. Export material handling machine 40

[0065] like Figure 1 and Figure 6-10 As shown, the outlet material handling machine 40 includes an outlet support 41, on which an outlet lifting frame 43, driven by an outlet hoisting mechanism 42, slides. The outlet lifting frame 43 is used to lift and lower the plates at the outlet of each storage platform in the bin 30.

[0066] Furthermore, such as Figure 7As shown, the outlet lifting frame 43 is equipped with a push-pull locking mechanism 45. The push-pull locking mechanism 45 includes horizontally sliding locking elements, which are arranged in at least two sets on opposite sides of the outlet lifting frame 43. Several vertically spaced support plates 411 are arranged on the outlet support 41 beside the locking elements. In specific implementation, the number and position of each support plate 411 correspond to the number and position of the storage platforms. During the lifting process, when the outlet lifting frame 43 is raised to the corresponding storage platform, the locking elements can slide horizontally to the supporting surface of the corresponding support plate 411 to support the outlet lifting frame 43, ensuring that the outlet lifting frame 43 remains stable and does not shake during the material discharge process.

[0067] In actual implementation, the push-pull locking mechanism 45 can also be used on the inlet stacker 10. Its installation method on the inlet stacker 10 is similar to that on the outlet reclaimer 40. The inlet lifting frame 13 in the inlet stacker 10 does not shake during the plate feeding process.

[0068] Furthermore, such as Figure 9 As shown, the locking component is a locking shaft 453. A shaft sleeve 452, fitted around the outer circumference of the locking shaft 453, is fixed on the outlet lifting frame 43. The lower outer end of the support plate 411 on the locking shaft 453 has a horizontal pressing surface. A slide rail 455, arranged parallel to the axial direction of the locking shaft 453, is installed on the outlet lifting frame 43. A sliding plate 454, connected to the inner end of the locking shaft 453, slides on the slide rail 455. A push-pull electric cylinder 451, which drives the sliding plate 454 to reciprocate, is also installed on the outlet lifting frame 43. The horizontal pressing surface increases the contact area between the locking component and the supporting surface, ensuring the stability of the locking component under load. Furthermore, the locking shaft 453 and the shaft sleeve 452 cooperate with each other, and the sliding cooperation between the slide rail 455 and the connecting sliding plate 454 prevents the locking shaft 453 from rotating. Compared to locking components that directly adopt rectangular or other non-circular structures, in this application, the circular cross-section of the locking shaft 453 is subjected to uniform stress, has good torsional and bending resistance, and the stress distribution of the circular cross-section is uniform, which can reduce stress concentration and is easy to process by turning, grinding and other processes, thus ensuring a high degree of fit between the locking shaft 453 and the shaft sleeve 452.

[0069] like Figure 9 As shown, the push-pull electric cylinder 451 is floatingly connected to the slide plate 454. The specific floating connection can be a universal joint or a cross linkage, which reduces the coaxiality requirement between the push-pull electric cylinder 451 and the locking round shaft 453, thereby reducing the installation difficulty of the push-pull electric cylinder 451.

[0070] Based on the above, to prevent minor machining deviations in the position of the support surface of the support plate 411, such as Figure 7As shown, a vertically arranged fine-tuning screw 412 is threaded onto the support plate 411. The head of the fine-tuning screw 412 protrudes from the upper surface of the support plate 411, and the upper surface of the head of the fine-tuning screw 412 forms a supporting surface. By rotating the fine-tuning screw 412, the height of the supporting surface can be adjusted.

[0071] When implementing, such as Figure 6 As shown, the outlet lifting frame 43 has a rectangular structure, and the locking components are arranged in four sets at the four corners of the outlet lifting frame 43, providing more even and stable support around the outer perimeter of the outlet lifting frame 43. Of course, in actual implementation, the number of locking components can also be set to other quantities, such as 5 or 6, as long as it can support the outlet lifting frame 43 during the material discharge process.

[0072] Based on the above, such as Figure 6 and Figure 10 As shown, at least two outlet support guide wheels 442 are rotatably fitted on the outlet lifting frame 43, which are horizontally spaced along the material discharge direction. The rotation axis of the outlet support guide wheels 442 is horizontal and perpendicular to the material discharge direction, which is used to reduce the frictional resistance between the material and the outlet lifting frame 43 during the material discharge process.

[0073] Furthermore, such as Figure 6 and Figure 10 As shown, guide frames 44 are installed on both sides of the lower part of the outlet lifting frame 43. The outlet support guide wheels 442 are arranged in two rows installed on the lower part of the guide frames 44 on both sides. The lower part of the outlet lifting frame 43, the inner side wall of the guide frames 44, and the top of the outer edge of all the outlet support guide wheels 442 together form a discharge channel for the sheet material to be discharged. By forming a discharge channel directly below the outlet lifting frame 43, it is possible to effectively prevent the sheet material from tipping over along the sheet material conveying direction during the discharge process. At the same time, it can also achieve positioning on both sides of the sheet material during the discharge process, ensuring stable discharge of the sheet material.

[0074] like Figure 8 As shown, the inner wall of the guide frame 44 is hinged to the side wall of the outlet lifting frame 43 via the outlet swing seat 441. The hinge axis of the outlet swing seat 441 is parallel to the horizontal discharge direction of the plate. A fine-tuning telescopic rod 46 is hinged between the top of the guide frame 44 and the outlet lifting frame 43. The hinge axes at both ends of the fine-tuning telescopic rod 46 are parallel to the hinge axis of the outlet swing seat 441. By contracting or extending the fine-tuning telescopic rod 46, the guide frame 44 can be rotated around the hinge axis of the outlet swing seat 441 to ensure that the axis of the outlet support guide wheel 442 on the guide frame 44 is horizontal and perpendicular to the discharge direction of the plate, thus improving the installation accuracy of the outlet support guide wheel 442.

[0075] Furthermore, such as Figure 10As shown, an outlet drive wheel 445, driven by an outlet drive motor 444, is mounted on the guide frame 44. The rotation axis of the outlet drive wheel 445 is parallel to the rotation axis of the outlet support guide wheel 442. Both the outlet drive motor 444 and the outlet drive wheel 445 are mounted on the outlet support platform 443, which is elastically connected to the guide frame 44. This allows the outer edge of the outlet drive wheel 445 to elastically extrude the sheet material in the discharge channel. Similar to the storage power assembly 35 in the hopper 30, the elastic extrusion of the outlet drive wheel 445 on the bottom of the sheet material creates sufficient friction between the outlet drive wheel 445 and the sheet material, ensuring stable contact between the outlet drive wheel 445 and the bottom of the sheet material even when there is wear on the outer surface of the outlet drive wheel 445. At this time, the rotation of the outlet drive wheel 445 drives the sheet material to move on the discharge platform.

[0076] Furthermore, such as Figure 10 As shown, one end of the outlet support platform 443 is hinged to the guide frame 44, and the hinge axis of the outlet support platform 443 is parallel to the rotation axis of the outlet drive wheel 445. In the non-working state, the outlet support platform 443 is driven by an elastic element, causing the top edge of the outlet drive wheel 445 to protrude into the discharge channel. At this time, the cantilever end of the outlet support platform 443 extends in the direction of the plate feeding. Similar to the storage power assembly 35 in the hopper 30, this allows the plate to press the outlet support platform 443 downwards with low resistance when it moves along the discharge direction and squeezes the outlet drive wheel 445. Compared to driving the outlet support platform 443 to move up and down via an elastic telescopic rod, there is less risk of transmission dead points. In addition, an outlet pad 448 fixedly connected to the guide frame 44 is fixedly connected directly above the outlet support platform 443. An outlet guide screw 446 penetrating the outlet pad 448 is swayingly connected to the upper part of the outlet support platform 443. The swing axis of the outlet guide screw 446 is parallel to the rotation axis of the outlet drive wheel 445. An elongated hole for the outlet guide screw 446 to pass through is opened on the outlet pad 448, and the length direction of the elongated hole is parallel to the length direction of the discharge channel. An outlet spring 447 and an outlet lower nut 4462 are respectively fitted on the rod body above and below the outlet pad 448 on the outlet guide screw 446. An outlet upper nut 4461 is also threadedly screwed onto the rod body above the outlet spring 447 on the outlet guide screw 446. Similar to the storage power assembly 35 inside the chamber 30, it can realize the positioning of the outlet drive wheel 445 and the initial elastic force adjustment of the outlet spring 447 in the non-working state. At the same time, it can also realize the elastic force adjustment of the outlet spring 447 in the working state.
