Description

Technical Field

[0001] This application relates to the field of powder forming technology, and in particular to a weighing mechanism and powder forming equipment. Background Technology

[0002] Powder forming equipment typically includes a powder forming press, a robotic arm, a weighing mechanism, and a loading / unloading mechanism. The powder forming press is used to batch-press powder filling multiple cavities in the mold panel to form multiple materials. Then, the robotic arm grabs multiple materials of the same batch and places them individually onto the weighing mechanism for weighing. After weighing, the robotic arm then places the same batch of materials into multiple mold cavities of the graphite plate in the loading / unloading mechanism for subsequent transfer operations.

[0003] However, in actual production, the spacing between the mold cavities may not match the spacing between the mold cavities. This would require the weighing mechanism to manually adjust the spacing according to the spacing between the mold cavities and the mold cavities, which is time-consuming and labor-intensive and affects production efficiency.

[0018] In the embodiments of this application, the terms "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," "fourth," "fifth," and "sixth" may explicitly or implicitly include one or more of that feature.

[0019] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0020] Reference Figures 1 to 10 As shown, this application provides a weighing mechanism, including a housing 100, an automatic telescopic variable pitch component 200, at least two load-bearing components 300, and at least two weighing components 400 corresponding one-to-one with the load-bearing components 300.

[0021] At least two load-bearing components 300 are distributed in parallel and spaced apart and are both located outside the housing 100. Each load-bearing component 300 has a load-bearing position 310 for carrying materials. A weighing component 400 is located inside the housing 100 and connected to the corresponding load-bearing component 300, and is used to measure and obtain the weight information of the materials on each load-bearing position 310.

[0022] The automatic telescopic variable pitch component 200 is located on the housing 100 and connected to the weighing component 400. The automatic telescopic variable pitch component 200 can extend and retract to drive the weighing component 400 to move and link with the bearing component 300 to adjust the distance between two adjacent bearing components 300. In practical implementation, at least two carrier components 300 can be along such a path. Figure 3 The x-direction shown is arranged in parallel intervals, and each bearing component 300 is provided with a bearing position 310 for bearing materials. When weighing is required, the material pressed by the powder forming press 630 can be picked up manually or by a robot and placed on the bearing position 310, and then weighed individually by the corresponding weighing component 400. One material is placed on each bearing position 310, and the spacing between adjacent bearing positions 310 is consistent with the spacing of the mold cavity of the mold panel 610 on the powder forming press 630 that carries the material. Thus, the batch material transfer and weighing operation can be directly realized manually or by a robot, so as to facilitate the subsequent individual weighing of each material.

[0023] Furthermore, an automatic telescopic variable pitch component 200 is provided inside the outer shell 100 of the weighing mechanism. The automatic telescopic variable pitch component 200 can automatically telescopic, thereby driving the weighing component 400 connected to it to move and change pitch, and ultimately driving the bearing component 300 connected to the weighing component 400 to move and change pitch, so that the distance between two adjacent bearing positions 310 or bearing components 300 changes to adapt to the spacing of the mold cavity of the graphite plate 620 placed on the loading and unloading mechanism 650.

[0024] For example, the automatic telescopic pitch-changing component 200 can extend and retract along the arrangement direction of the support component 300, thereby adjusting the spacing between two adjacent support components 300 along the arrangement direction of the support components 300 when the weighing component 400 moves to change the pitch. Alternatively, the automatic telescopic pitch-changing component 200 can also extend and retract along a direction perpendicular to the arrangement direction of the support components 300, thereby adjusting the spacing between two adjacent support components 300 along a direction perpendicular to the arrangement direction of the support components 300 when the weighing component 400 moves to change the pitch, to adapt to different usage scenarios.

[0025] Specifically, before weighing, the automatic telescopic pitch component 200 can extend and eventually move the bearing component 300 until the distance between two adjacent bearing positions 310 is consistent with the distance between the cavities on the mold panel 610. Then, the batch of materials on the mold panel 610 are picked up manually or by a robot 640 and placed onto each bearing position 310 of the weighing mechanism for individual weighing, so as to facilitate quality control based on the weight information. After weighing, the automatic telescopic pitch component 200 extends and eventually moves the bearing component 300 until the distance between two adjacent bearing positions 310 is adjusted to be consistent with the distance between the cavities on the graphite plate 620 on the loading and unloading mechanism 650. Then, the materials on the weighing mechanism are picked up manually or by a robot 640 and placed into the cavity of the graphite plate 620 on the loading and unloading mechanism 650 for subsequent material transfer operations.

[0026] Therefore, the weighing mechanism of this embodiment can adjust the spacing between adjacent bearing components 300 through the automatic telescopic variable pitch component 200, thereby improving the compatibility with the spacing of other components used for carrying materials. This facilitates the batch transfer of materials between different mechanisms, thereby improving operational flexibility and work efficiency.

[0027] Furthermore, in this embodiment, the support component 300 is disposed outside the housing 100, thereby facilitating the transfer and placement of materials on the support component 300. Specifically, the support component 300 can be placed on the top of the housing 100, and a support position 310 can be formed on the top surface of the support component 300.

[0028] For example, the material can be a pressed material formed by pressing powder, or it can be other materials.

[0029] The weighing mechanism of this embodiment includes a housing 100, an automatic telescopic variable pitch assembly 200, at least two load-bearing components 300, and at least two weighing components 400 corresponding to each load-bearing component 300. The at least two load-bearing components 300 are distributed in parallel at intervals and are all located outside the housing 100. Each load-bearing component 300 has a load-bearing position 310 for individually placing each material. The weighing components 400 are located inside the housing 100 and connected to the corresponding load-bearing components 300, and are used to measure and acquire the weight information of the material at the load-bearing position 310, thereby achieving individual weighing of each material. Meanwhile, an automatic telescopic pitch-changing component 200 connected to the weighing component 400 is provided on the outer casing 100. The automatic telescopic pitch-changing component 200 can extend and retract to drive the weighing component 400 to move and link with the bearing component 300, thereby adjusting the distance between two adjacent bearing components 300, and then adjusting the distance between two adjacent bearing positions 310 to adapt to the distance between the mold cavities on the mold panel 610 of the powder molding press and the distance between the mold cavities of the graphite plates 620 for loading and unloading, thereby realizing automated pitch-changing operation to save manpower and improve operating efficiency.

[0030] Reference Figures 4 to 10 As shown, in some embodiments, the automatic telescopic variable pitch assembly 200 includes a drive component 210, a transmission component 220, and a linkage telescopic assembly 230.

[0031] The driving component 210 is connected to the transmission component 220, and the linkage telescopic component 230 is connected to the transmission component 220 and each weighing component 400 respectively, so that when the driving component 210 drives the transmission component 220 to move, the linkage telescopic component 230 extends and retracts to adjust the distance between two adjacent weighing components 400.

[0032] In practice, when a pitch change is required, the drive component 210 drives the transmission component 220 to move. The movement of the transmission component 220 and the linkage telescopic component 230 extend and retract in conjunction with it. The extension and retraction of the linkage telescopic component 230 and the movement of the weighing component 400 connected to it, and finally the movement of the bearing component 300 through the weighing component 400, so as to adjust the distance between the bearing positions 310 of the two adjacent bearing components 300.

[0033] For example, when it is necessary to increase the distance between two bearing positions 310, the driving component 210 can be set to rotate forward and drive the transmission component 220 to rotate. The rotation of the transmission component 220 drives the linkage telescopic component 230 to extend. The extension of the linkage telescopic component 230 drives the weighing component 400 to move, thereby increasing the distance between two adjacent weighing components 400. The movement of the weighing component 400 also moves the bearing component 300 in conjunction with it, ultimately increasing the distance between two adjacent bearing components 300, so as to achieve the purpose of increasing the distance between adjacent bearing positions 310.

[0034] Conversely, when it is necessary to reduce the distance between two bearing positions 310, the drive component 210 can be set to reverse, for example, and drive the transmission component 220 to rotate. The rotation of the transmission component 220 drives the linkage telescopic component 230 to retract. The retraction of the linkage telescopic component 230 drives the weighing component 400 to move, thereby reducing the distance between two adjacent weighing components 400. The movement of the weighing component 400 also moves the bearing component 300 in conjunction with it, ultimately reducing the distance between two adjacent bearing components 300, thus achieving the purpose of reducing the distance between adjacent bearing positions 310.

[0035] For example, the drive component 210 can be a motor, a cylinder, or a hydraulic cylinder.

[0036] Reference Figure 7 and Figure 10 As shown, in some embodiments, the linkage telescopic assembly 230 includes one or at least two mutually hinged quadrilateral linkage structures 231. At least two quadrilateral linkage structures 231 are arranged along the moving direction of the bearing assembly 300, and adjacent quadrilateral linkage structures 231 are hinged. The quadrilateral linkage structure 231 is connected to at least two weighing assemblies 400, and any one quadrilateral linkage structure 231 is connected to the transmission assembly 220 for transmission.

[0037] For example, when there are two weighing components 400, a quadrilateral link structure 231 can be set up, and the hinges 232 at the two hinge points of the quadrilateral link structure 231 are respectively connected to the weighing components 400 one by one.

[0038] When the weighing components 400 are set to two or more, for example, as shown in the figure Figure 5 and Figure 7 When four are shown, the quadrilateral link structure 231 can be set to three. The four hinges 232 arranged side by side in the three quadrilateral link structures 231 are respectively connected to the four weighing components 400 one by one. That is, the number of quadrilateral link structures 231 is always one less than the number of weighing components 400.

[0039] One of the quadrilateral link structures 231 is connected to the transmission component 220. When the transmission component 220 moves, it causes the quadrilateral link structure 231 to extend or retract. The quadrilateral link structure 231 will then retract or extend synchronously with all the other quadrilateral link structures 231. Furthermore, all the quadrilateral link structures 231 can be set to have the same size specifications. This ensures that the extension and retraction stroke of each quadrilateral link structure 231 is consistent. As a result, when all the load-bearing components 300 move, the change in the distance between any two adjacent load-bearing components 300 is consistent, so as to adapt to the uniformly spaced mold cavities or mold holes.

[0040] For example, the quadrilateral link structure 231 can specifically be a parallelogram link structure.

[0041] Furthermore, each quadrilateral link structure 231 includes four links 233 connected end to end, and two adjacent links 233 are hinged together by hinges 232, so that the quadrilateral link structure 231 can extend or retract.

[0042] For two adjacent quadrilateral linkage structures 231, the two sets of linkages in the two adjacent quadrilateral linkage structures 231 can be made of a single connecting rod 234. Each set of linkages includes two collinearly arranged connecting rods 233. That is, half of a single connecting rod 234 is a connecting rod 233 of one quadrilateral linkage structure 231, and the other half is a connecting rod 233 of the other quadrilateral linkage structure 231. The two adjacent quadrilateral linkage structures 231 have a total of two sets of adjacent connecting rods 233, that is, there are two single connecting rods 234. These two single connecting rods 234 are cross-hinged, and the hinge 232 at the cross position can be used to connect with the weighing assembly 400.

[0043] For example, for three quadrilateral linkage structures 231, the hinges 232 at the two intersections of the middle quadrilateral linkage structure 231 are used to connect the two middle weighing components 400 respectively, and the hinges 232 at the outermost hinge points of the two outermost quadrilateral linkage structures 231 at non-intersections are used to connect the two outermost weighing components 400 respectively. Here, "middle" and "outer" refer to the extension and contraction direction of the quadrilateral linkage structure 231, that is, based on... Figure 7 In the x-direction, there are a total of four hinges 232 in the middle row of all the quadrilateral linkage structures 231. The two middle hinges 232 are connected to the two middle weighing components 400 in a one-to-one correspondence, and the two outer hinges 232 are connected to the two outer weighing components 400 in a one-to-one correspondence.

[0044] For example, the load-bearing component 300 and the weighing component 400 are both set as follows: Figure 3As shown in the diagram, there are four quadrilateral link structures 231, but three can be configured. For example, the outermost quadrilateral link structure 231 can be connected to the transmission assembly 220. When pitch adjustment is required, the drive component 210 drives the transmission assembly 220 to move. The movement of the transmission assembly 220 causes the outermost quadrilateral link structure 231 connected to it to extend or retract. The movement of this quadrilateral link structure 231 will cause the other two quadrilateral link structures 231 to extend or retract synchronously, thereby causing the bearing assembly 300 to move, so that the distance between any two bearing assemblies 300 can be adjusted by an equal amount.

[0045] Reference Figures 4 to 10 As shown, in some embodiments, the transmission assembly 220 includes a transmission screw structure 221 and a transmission nut structure 222. The transmission screw structure 221 is in transmission cooperation with the driving member 210. The transmission nut structure 222 is disposed on the transmission screw structure 221 and connected to the connecting rod telescopic assembly 230. The driving member 210 is used to drive the transmission screw structure 221 to rotate so as to drive the transmission nut structure 222 to move. The movement of the transmission nut structure 222 and the linkage telescopic assembly 230 are linked to extend and retract.

[0046] In practice, when pitch adjustment is required, the drive component 210 drives the transmission screw structure 221 to rotate. That is, the transmission screw structure 221 can be connected to the output shaft of the drive component 210. The rotation of the transmission screw structure 221 drives the transmission nut structure 222 set on it to move along the axial direction of the transmission screw structure 221. The movement of the transmission nut structure 222 drives the connecting rod telescopic assembly 230 to extend or retract, so as to ultimately drive the load-bearing assembly 300 to move through the movement of the weighing assembly 400, thereby realizing the adjustment of the distance between two adjacent load-bearing assemblies 300.

[0047] For example, when it is necessary to increase the distance between two load-bearing components 300, the drive member 210 can be set to rotate forward. The forward rotation of the drive member 210 drives the transmission screw structure 221 to rotate. The rotation of the transmission screw structure 221 drives the transmission nut structure 222 to move along the extension direction of a quadrilateral link structure 231 connected to it. The extension of the quadrilateral link structure 231 drives all other quadrilateral link structures 231 that are hinged to each other to extend synchronously. When the quadrilateral link structure extends, it drives the weighing component 400 connected to it to move and increases the distance between two adjacent weighing components 400. Finally, it drives the load-bearing component 300 to move, so that the distance between any two load-bearing components 300 can be increased by the same amount.

[0048] Conversely, when it is necessary to reduce the distance between two load-bearing components 300, for example, the drive component 210 can be reversed. The reverse rotation of the drive component 210 drives the transmission screw structure 221 to rotate. The rotation of the transmission screw structure 221 drives the transmission nut structure 222 to move along the direction of the contraction of a quadrilateral link structure 231 connected to it. The contraction of the quadrilateral link structure 231 drives all other quadrilateral link structures 231 that are hinged to each other to contract synchronously. When the quadrilateral connection structure contracts, it drives the weighing component 400 connected to it to move and reduces the distance between two adjacent weighing components 400. Finally, it drives the load-bearing component 300 to move, so that the distance between any two load-bearing components 300 is reduced by the same amount.

[0049] Reference Figures 4 to 10 As shown, in some embodiments, the transmission screw structure 221 includes a synchronous pulley structure 223 and a transmission screw 224. The synchronous pulley structure 223 is in transmission cooperation with the driving member 210 and the transmission screw 224 respectively. The driving member 210 drives the synchronous pulley structure 223 to rotate and drives the transmission screw 224 to rotate in conjunction.

[0050] In practice, when pitch adjustment is required, the drive component 210 drives the synchronous pulley structure 223 to rotate. The transmission screw 224 is connected to the synchronous pulley structure 223, so that when the synchronous pulley structure 223 rotates, it drives the transmission screw 224 to rotate. Since the outer wall of the transmission screw 224 is provided with threads that mesh with the transmission nut structure 222, when the transmission screw 224 rotates, it will drive the transmission nut structure 222 to move axially, and finally drive the bearing component 300 to move, thereby realizing pitch adjustment.

[0051] Specifically, the synchronous belt pulley structure 223 includes a main drive pulley 227, a secondary drive pulley 228, and a transmission belt 229. The main drive pulley 227 is connected to the output shaft of the drive unit 210, and the secondary drive pulley 228 is connected to the transmission screw 224. The transmission belt 229 is fitted onto the main drive pulley 227 and the secondary drive pulley 228. When the drive unit 210 drives the main drive pulley 227 to rotate, the rotation is transmitted to the secondary drive pulley 228 via the transmission belt 229. The rotation of the secondary drive pulley 228 drives the transmission screw 224 to rotate, which in turn drives the transmission nut structure 222 to move axially, ultimately moving the load-bearing assembly 300 to achieve spacing adjustment.

[0052] For example, the main drive wheel 227 and the secondary drive wheel 228 can be pulleys, and the drive belt 229 can be a drive belt. Alternatively, the main drive wheel 227 and the secondary drive wheel 228 can be sprockets, and the drive belt 229 can be a drive chain.

[0053] Reference Figures 4 to 10As shown, in some embodiments, the transmission nut structure 222 includes a transmission nut 225 and a moving block 226. The transmission nut 225 is disposed on the transmission screw structure 221, and the moving block 226 is disposed on the transmission nut 225 and connected to the connecting rod telescopic assembly 230.

[0054] In practice, when pitch adjustment is required, the drive component 210 drives the synchronous pulley structure 223 to rotate. The transmission screw 224 is connected to the synchronous pulley structure 223, so that when the synchronous pulley structure 223 rotates, it drives the transmission screw 224 to rotate. Since the outer wall of the transmission screw 224 is provided with threads that mesh with the transmission nut 225, when the transmission screw 224 rotates, it will drive the transmission nut 225 to move axially. When the transmission nut 225 moves, it drives the moving block 226 set on it to move. The movement of the moving block 226 drives the connecting rod telescopic assembly 230 connected to it to extend and retract. The extension and retraction of the connecting rod telescopic assembly 230 drives the weighing assembly 400 to move, and finally, the movement of the weighing assembly 400 drives the bearing assembly 300 to move, thereby realizing the pitch adjustment.

[0055] The specific operation process is briefly described as follows: For example, when it is necessary to increase the distance between two adjacent load-bearing components 300, the drive component 210 can be set to rotate forward, driving the main drive wheel 227 to rotate forward. The main drive wheel 227 rotates forward, driving the secondary drive wheel 228 to rotate in reverse. The secondary drive wheel 228 rotates in reverse, driving the transmission screw 224 to rotate in reverse. The transmission screw 224 rotates in reverse, driving the transmission nut 225 to move along the direction of the tensioning quadrilateral linkage structure 231. Finally, through the moving block 226, one of the quadrilateral linkage structures 231 is stretched. This stretching of the quadrilateral linkage structure 231 and the simultaneous stretching of all other quadrilateral linkage structures 231 are linked together, ultimately driving the weighing component 400 to move. The movement of the weighing component 400 drives the load-bearing component 300 to move, ultimately increasing the distance between two adjacent load-bearing components 300. The entire operation process does not require manual pitch adjustment, thus saving time and effort, and the accuracy of pitch adjustment is also high. The reverse is also the same, and will not be elaborated here.

[0056] Reference Figures 3 to 10 As shown, in some embodiments, the weighing assembly 400 includes a frame 410 and a weighing sensor disposed within the frame 410. The frame 410 is slidably disposed within the housing 100 and connected to the linkage telescopic assembly 230.

[0057] In specific implementation, the frame 410 is installed inside the housing 100 and is used to support the load cell, which is used to weigh the material on the support position 310 individually. Since the support component 300 is connected to the weighing component 400, the weight information measured by the load cell is the total weight of the support component 300 and the material. Therefore, in order to facilitate the acquisition of the material weight, the weight of the support component 300 itself can be removed before weighing. That is, when the load cell is zeroed, the weight of the support component 300 itself has been reduced, and the final weight measured by the load cell is only the weight of the material.

[0058] Furthermore, the frame 410 is slidably disposed within the housing 100 and connected to the linkage telescopic assembly 230. When the pitch is changed, the linkage telescopic assembly 230 extends and retracts, causing the frame 410 to move relative to the housing 100 along the extension and retraction direction of the linkage telescopic assembly 230. This direction of movement is specifically the arrangement direction of the multiple bearing components 300 or perpendicular to the arrangement direction of the bearing components 300, which can ultimately drive the bearing components 300 to move, thereby adjusting the distance between two adjacent bearing components 300.

[0059] Reference Figures 4 to 6 As shown, in some embodiments, the frame 410 includes a base 411 and a frame body 412 disposed on the base 411. The base 411 is slidably disposed on the housing 100 and connected to the linkage telescopic assembly 230. The weighing sensor is disposed inside the frame body 412. In the direction of movement along the base 411, at least one of the opposite sides of the frame body 412 is provided with an opening, and a first protective member 510 is provided at the opening.

[0060] In a specific implementation, in order to assemble the load cell, the frame 410 can be configured as a frame body 412 with openings on both sides. For example, the frame 410 can be configured with the front and rear sides on both sides along its moving direction, and the front and rear sides of the frame body 412 can be designed as open. In this case, the load cell can be assembled into the frame body 412 from the front side or from the rear side of the frame body 412.

[0061] Furthermore, to prevent material dust on the bearing position 310 from falling into the frame body 412 through the open structure and affecting the measurement accuracy of the weighing sensor, a first protective component 510 can be installed at the open for sealing.

[0062] For example, the first protective element 510 can be a protective plate adapted to the contour of the opening. The protective plate itself can be snapped into the opening, or it can be opened and closed by sliding along a slide rail or by rotating a hinge.

[0063] In addition, the base 411 is slidably disposed within the housing 100 and connected to the linkage telescopic assembly 230. When the pitch is changed, the linkage telescopic assembly 230 extends and retracts, causing the base 411 to move relative to the housing 100 along the extension and retraction direction of the linkage telescopic assembly 230. This can then ultimately drive the bearing assembly 300 to move, so as to adjust the distance between two adjacent bearing assemblies 300.

[0064] For example, the base 411 and the frame body 412 can be connected by fasteners such as screws, or they can be snap-fitted or integrally formed.

[0065] Reference Figures 3 to 10 As shown, in some embodiments, at least one of the housing 100 and the frame 410 is provided with a slide groove 110, and at least one of the housing 100 and the frame 410 is provided with a slider 420. The slider 420 is slidably disposed in the corresponding slide groove 110, and the slide groove 110 extends along the extension direction of the automatic telescopic variable pitch assembly 200, thereby realizing reliable and smooth movement of the frame 410 relative to the housing 100.

[0066] Specifically, a groove 110 can be provided on the outer casing 100, and a slider 420 can be provided on the frame 410. Alternatively, a slider 420 can be provided on the outer casing 100, and a groove 110 can be provided on the frame 410.

[0067] In addition, to make the movement of the frame 410 smoother, two slides 110 and two sliders 420 can be provided. That is, a slide 110 and a slider 420 can be provided on both sides perpendicular to the movement direction of the frame 410 to guide and constrain the movement of the frame 410.

[0068] Reference Figure 6 As shown, in some embodiments, the base 411 includes at least four base plates 413, at least one of which is arranged end to end to form a cavity. The connecting rod telescopic assembly 230 is located in the cavity, and one of the base plates 413 is provided with a clearance hole through which the hinge 232 of the connecting rod telescopic assembly 230 can pass. After passing through the clearance hole, the hinge 232 is connected to the transmission nut structure 222.

[0069] In a specific implementation, the base 411 consists of four base plates 413, which are connected end to end to form a cavity. The connecting rod telescopic assembly 230 is located inside the cavity to effectively utilize the space to arrange the connecting rod telescopic assembly 230.

[0070] Meanwhile, the hinge 232 of the hinged linkage telescopic assembly 230 is used to connect with the transmission nut structure 222 and the base plate 413. That is, the hinge 232 of the linkage telescopic assembly 230 itself is used to connect the linkage telescopic assembly 230, the frame 410 of the weighing assembly 400 and the transmission nut structure 222 together to achieve linkage and cooperation, and can save parts and simplify the structural design.

[0071] For example, the hinge 232 can be a hinge shaft or a pin.

[0072] Reference Figure 8 and Figure 9 As shown, in some embodiments, a mounting plate 120 is provided on the side of the housing 100 away from the support component 300, and the automatic telescopic pitch component 200 is disposed on the mounting plate 120, thereby realizing a reliable connection between the automatic telescopic pitch component 200 and the housing 100.

[0073] In addition, a protective mesh cover 130 can be provided around the edge of the outer shell 100 on the side opposite to the weighing component 400, and the automatic telescopic variable pitch component 200 is located inside the protective mesh cover 130 to play a role in preventing collision protection.

[0074] For example, the mounting plate 120, the protective mesh cover 130 and the outer shell 100 can be welded, snapped or screwed together.

[0075] Reference Figures 3 to 10 As shown, in some embodiments, the load-bearing component 300 includes a groove 320 and a connecting plate 330. The groove 320 is disposed on the side of the connecting plate 330 away from the weighing component 400, the load-bearing position 310 is disposed in the groove 320, and the connecting plate 330 is connected to the weighing component 400.

[0076] The connecting plate 330 includes a horizontal plate 331 and a vertical plate 332 connected to the horizontal plate 331. The vertical plate 332 is connected to the groove 320, and the horizontal plate 331 is connected to the weighing component 400. A second protective member 520 is provided on the side of the horizontal plate 331 away from the weighing component 400, and the second protective member 520 covers at least one weighing component 400.

[0077] In practice, the groove 320 is provided with a bearing position 310 for placing materials, and the connecting plate 330 is used to connect the groove 320 to the weighing component 400 so that the weighing component 400 can weigh the materials.

[0078] Specifically, the groove 320 is located at the top of the housing 100, and one side of the top wall of the housing 100 is lower than the top surface of the housing 100 to form a notch, so that the connecting plate 330 can extend into the housing 100 through the notch and connect with the weighing component 400 inside the housing 100. In addition, the housing 100 can be an open structure at the top. In this case, in order to prevent the powder of the material on the bearing position 310 from falling onto the weighing component 400 inside the housing 100 through the opening, a second protective member 520 can be provided at the opening. Specifically, in order not to affect the connection between the connecting plate 330 of each bearing component 300 and the weighing component 400, the connecting plate 330 can be configured as an L-shaped connecting plate 330 consisting of a horizontal plate 331 and a vertical plate 332. The horizontal plate 331 is located on the side of the second protective member 520 away from the groove 320, that is, the horizontal plate 331 is located between the second protective member 520 and the weighing component 400, so as to facilitate connection with the weighing component 400. The second protective member 520 can prevent the powder of the material on the groove 320 from falling into the outer casing 100.

[0079] The second protective component 520 can be a protective plate, which can cover at least one weighing component 400, for example, it can cover one weighing component 400 to protect it from falling dust, or it can cover two or all weighing components 400 to protect the covered weighing components 400 from falling dust. In this embodiment, the protective plate can cover all weighing components 400.

[0080] Reference Figures 1 to 10 As shown in the figure, this application embodiment provides a powder forming equipment 600, including a weighing mechanism.

[0081] The specific structure and implementation principle of the weighing mechanism in this embodiment are the same as those of the weighing mechanism provided in the above embodiments, and can bring the same or similar technical effects. They will not be described in detail here, but can be referred to the description of the above embodiments.

[0082] Specifically, the powder forming equipment 600 includes a powder forming press 630, a robotic arm 640, a weighing mechanism, and a loading / unloading mechanism 650. The powder forming press 630 is used to batch press powder filling multiple cavities in the mold panel 610 to form multiple materials. Then, the robotic arm 640 grabs multiple materials of the same batch and places them onto the weighing mechanism for individual weighing. After weighing, the robotic arm 640 places the same batch of materials into multiple cavities of the graphite plate 620 of the loading / unloading mechanism 650, and then transfers them via a transfer cart 660.

[0083] For example, when the spacing between the mold cavities differs from the spacing between the mold chambers, the automatic telescopic pitch-changing component 200 can first adjust the spacing of the carrying components 300 to match the spacing between the mold cavities. This allows the robot arm 640 to grab multiple materials from multiple mold cavities together and place them in their respective carrying positions 310, so that the materials can be weighed individually by the corresponding weighing structure. After weighing, when the materials need to be transferred via the loading / unloading mechanism 650, the automatic telescopic pitch-changing component 200 can adjust the spacing of the carrying components 300 to match the spacing between the mold cavities. This allows the robot arm to grab the materials and place them one by one into the mold cavities for subsequent transfer operations. The automatic pitch-changing operation in this embodiment not only saves time and effort but also improves the flexibility and efficiency of material production.

[0085] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
