Detailed implementation manners

[0046] The following refers to Figures 1 to 5 to describe an impeller molding machine according to an embodiment of the present utility model. In the description of this embodiment, it should be understood that the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features, that is, including one or more of such features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined. When a certain feature "includes or contains" a certain or certain features it covers, unless otherwise specifically described, this indicates that other features are not excluded and other features may be further included.

[0047] In the description of this embodiment, the descriptions with reference to terms such as "one embodiment", "some embodiments", "schematic embodiments", "examples", "specific examples", or "some examples" mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model. In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0048] Figure 1 is a schematic diagram of the external structure according to an embodiment of the present utility model. As Figure 1 shown, and in combination with Figures 2 to 5 , the present utility model provides an impeller forming machine 1. The above impeller forming machine 1 includes a workbench 100, a glue injection mechanism 200, and a forming mechanism 300. A first turntable 110 is provided on the tabletop of the workbench 100, and a first working position 111 is provided on the upper surface of the first turntable 110. The first working position 111 can be used to place the substrate of the impeller. When the substrate is placed on the first working position 111, the first working position 111 can enable the substrate to rotate circumferentially. The glue injection mechanism 200 and the forming mechanism 300 are arranged in sequence along the rotation direction of the first turntable 110 during operation. The glue injection mechanism 200 injects glue onto the substrate placed on the first working position 111, so that the surface of the substrate is evenly coated with glue. The forming mechanism 300 pastes sandpaper on the substrate after injecting glue to prepare the impeller. It should be noted that the center of the substrate has a through hole.

[0049] The specific working process includes: The substrate of the impeller is placed on the first working position 111, and the position of the substrate changes as the first turntable 110 rotates. When the first working position 111 rotates to the lower part of the glue injection mechanism 200, that is, when the substrate is under the glue injection mechanism 200, the glue injection mechanism 200 outputs glue and injects glue onto the substrate, and the glue is smeared on the surface of the substrate. The substrate smeared with glue continues to move with the first working position 111. When the first working position 111 runs to the lower part of the forming mechanism 300, that is, when the substrate smeared with glue on the surface is under the forming mechanism 300, the forming mechanism 300 is started to paste the sandpaper on the substrate to prepare the impeller. It should be noted that when the glue injection mechanism 200 injects glue onto the substrate and the forming mechanism 300 pastes the sandpaper on the substrate, the first turntable 110 pauses for a first preset duration.

[0050] In the impeller forming machine provided by the present utility model, the glue injection onto the substrate and the pasting of sandpaper on the substrate are both automatically operated by the machine, realizing the automatic production of the impeller, reducing the input of human resources, and improving the production efficiency. At the same time, because the human factor is reduced, the error in the production process can be effectively avoided, thereby improving the consistency of the product.

[0051] In some embodiments of the present utility model, there are multiple first workstations 111. In this embodiment, multiple first workstations 111 are arranged on the first turntable 110, enabling the continuous operation of the impeller molding machine.

[0052] In some embodiments of the present utility model, the multiple first workstations 111 are evenly distributed along the circumferential direction of the first turntable 110. The multiple mentioned here can be any integer value of two or more, such as 2, 4, 5, etc., and preferably 8. The degree of the angle formed by the connecting lines of the injection mechanism 200 and the molding mechanism 300 with the axis of the first turntable 110 is an integer multiple of the central angle of two adjacent first workstations 111, and the integer mentioned here is less than the number of first workstations 111.

[0053] Specifically, when injecting glue under the injection mechanism 200 at one first workstation 111, another first workstation 111 is located under the molding mechanism 300. During continuous production, the injection of glue by the injection mechanism 200 to one substrate and the pasting of abrasive cloth by the molding mechanism 300 to another substrate can be carried out simultaneously.

[0054] In this embodiment, the arrangement of the first workstation 111, the injection mechanism 200, and the molding mechanism 300 can avoid the pause time during the rotation of the first turntable 110, further improving production efficiency.

[0055] In some embodiments of the present utility model, the impeller molding machine further includes a shaping mechanism 400. The shaping mechanism 400 is arranged on the tabletop of the workbench 100, and the shaping mechanism 400 shapes the impeller.

[0056] Specifically, the impeller continues to rotate on the first workstation 111 as the first turntable 110 rotates. When the impeller rotates to the position of the shaping mechanism 400, the shaping mechanism 400 trims the impeller.

[0057] In this embodiment, by arranging the shaping mechanism 400 to trim the impeller, the prepared impellers are more neat and the consistency between different impellers can also be improved.

[0058] In some embodiments of the present utility model, the injection mechanism 200, the molding mechanism 300, and the shaping mechanism 400 are arranged in sequence. The degree of the angle formed by the connecting lines of the injection mechanism 200 and the molding mechanism 300 with the axis of the first turntable 110 is an integer multiple of the central angle of two adjacent first workstations 111, and the degree of the angle formed by the connecting lines of the molding mechanism 300 and the shaping mechanism 400 with the axis of the first turntable 110 is an integer multiple of the central angle of two adjacent first workstations 111. The integer mentioned here is less than the number of first workstations 111.

[0059] In some embodiments of the present utility model, the impeller forming machine further includes a stock preparation machine 500. The stock preparation machine 500 is used to place the abrasive cloth, is disposed adjacent to the forming mechanism 300, and conveys the abrasive cloth to the forming mechanism 300.

[0060] Specifically, the stock preparation machine 500 is disposed outside the first turntable 110 and is adjacent to the forming mechanism 300. Before the impeller forming machine operates, abrasive cloth is pre-placed on the stock preparation machine 500, and one end of the abrasive cloth is connected to the forming mechanism 300. When the impeller forming machine operates, under the traction of the forming mechanism 300, the abrasive paper moves towards the forming mechanism 300.

[0061] In this embodiment, by providing the stock preparation machine 500, a position for pre-storing the abrasive paper is provided, and continuous supply of the abrasive paper is achieved when the impeller forming machine operates.

[0062] As Figure 2 shown, in some embodiments of the present utility model, the stock preparation machine 500 includes a second frame body 510 and a material retaining disk 520. A first through rod 511 is disposed on the second frame body 510, and the material retaining disk 520 is disposed on the outer periphery of the first through rod 511.

[0063] Specifically, it is set in a disk shape, the abrasive paper disk is installed on the frame body through the first through rod 511, and one side contacts the material retaining disk 520. When feeding, the abrasive paper disk rotates, and the material retaining disk 520 limits the movement of the abrasive paper in the horizontal direction.

[0064] In some embodiments of the present utility model, the stock preparation machine 500 further includes a transmission motor 530. The transmission motor 530 is installed on the second frame body 510, and when the transmission motor 530 operates, it drives the abrasive paper to move.

[0065] As Figure 1 shown, in some embodiments of the present utility model, the impeller forming machine further includes a blanking mechanism 700. In this embodiment, the blanking mechanism 700 removes the shaped grinding wheel from the first station 111.

[0066] In this embodiment, by providing the blanking mechanism 700, the mechanization degree of the production process is further improved, the input of human resources is reduced, the opportunity of human-machine contact is reduced, and the overall safety is increased.

[0067] As Figure 3 shown, in some embodiments of the present utility model, the impeller forming machine further includes a loading mechanism 600. In this embodiment, the loading mechanism 600 moves the matrix of the unglued grinding wheel to the first station 111. The safety and efficiency of the production process are further improved.

[0068] In some embodiments of the present utility model, the impeller forming machine includes a workbench 100. A first turntable 110 is provided on the tabletop of the workbench 100, and a first station 111 for placing the substrate is provided on the first turntable 110. It further includes a feeding mechanism 600, a glue injection mechanism 200, a forming mechanism 300, a forming mechanism 300, a shaping mechanism 400, and a blanking mechanism 700, which are sequentially arranged along the rotation direction of the first turntable 110 when it works.

[0069] In this embodiment, the feeding mechanism 600 places the substrate of the grinding wheel on the first station 111. As the grinding wheel rotates, the first station 111 passes through the glue injection mechanism 200, the forming mechanism 300, and the shaping mechanism 400 in sequence to inject glue into the substrate, paste abrasive cloth, and correct the impeller. Finally, the blanking mechanism 700 removes the trimmed grinding wheel from the first station 111.

[0070] As Figure 2 and Figure 3 shown, in this embodiment, the feeding mechanism 600, the glue injection mechanism 200, the forming mechanism 300, the forming mechanism 300, the shaping mechanism 400, and the blanking mechanism 700 are sequentially arranged around the first turntable 110, with a compact layout, reducing the floor area of the machine.

[0071] In some embodiments of the present utility model, the glue injection mechanism 200 includes a detection device 210, a glue pump 220, and a glue outlet 230. The detection device 210 is used to detect whether there is a substrate below the glue injection mechanism 200. The glue pump 220 is used to pump glue. The glue outlet 230 is connected to the glue pump 220. The glue enters the glue outlet 230 from the glue pump 220 and is applied to the substrate through the outlet of the glue outlet 230.

[0072] Specifically, when the first turntable 110 rotates and the first station 111 drives the substrate to reach below the detection device 210, the detection trigger is activated to detect whether there is a substrate on the first station 111. When it is detected that there is a substrate on the first station 111, a command is sent to the glue pump 220, and the glue pump 220 is activated to pump glue to the glue outlet 230. The glue flows out from the outlet of the glue outlet 230 and is coated on the substrate. The glue pump 220 continuously heats the glue during the working process to ensure that the glue has appropriate fluidity.

[0073] In this embodiment, the detection device 210 is provided to control the accuracy of glue injection.

[0074] In some embodiments of the present utility model, the glue injection mechanism 200 further includes a glue injection cylinder 240. When the detection device 210 detects the substrate, it presses the substrate and sends a command to the glue injection cylinder 240, and the glue outlet 230 discharges glue, so that the glue is evenly applied to the substrate.

[0075] In this embodiment, the glue injection cylinder 240 controls the amount of glue discharged from the glue outlet 230.

[0076] As Figure 3 shown, in some other embodiments of the present utility model, the detection mechanism includes a detection cylinder. When the detection cylinder detects the substrate, the detection cylinder presses the substrate tightly. In this embodiment, the detection cylinder presses the substrate tightly to prevent the substrate from moving, making the glue coating on the substrate more uniform.

[0077] As Figure 5 shown, in some embodiments of the present utility model, the forming mechanism 300 includes a feeding device 310, a pressing cylinder 330, an eccentric shaft motor 360, a chassis box body 320, a balance weight 350, an eccentric shaft 340, an eccentric shaft connecting rod 370, a slide rail 380 and a metal alloy blade 390. The feeding device 310 is connected to the stock preparation machine 500 for conveying sandpaper to the forming mechanism 300, and the feeding device 310 is located above a first working station 111. The pressing cylinder 330, the eccentric shaft motor 360, the balance weight 350, the eccentric shaft 340, the eccentric shaft connecting rod 370, the slide rail 380 and the metal alloy blade 390 are all arranged on the chassis box body 320.

[0078] During operation, the first turntable 110 rotates to rotate the substrate with glue applied to it under the alloy blade. The eccentric shaft motor 360, the feeding motor and the pressing cylinder 330 work simultaneously. The rotation of the eccentric shaft motor 360 drives the rotation of the eccentric shaft 340, thereby causing the eccentric shaft connecting rod 370 to rotate. The rotation of the eccentric connecting rod drives the movement of the slide rail 380, and the movement of the slide rail 380 drives the alloy blade to cut the sandpaper, so that the sandpaper is pasted on the substrate to produce a grinding wheel. By adjusting the pulse parameters of the eccentric shaft motor 360, the cutting length of the sandpaper can be controlled. The accuracy can be controlled within 0.3 mm.

[0079] In a further embodiment of the present utility model, the feeding device 310 includes a sandpaper belt groove. In this embodiment, the sandpaper belt groove defines the moving direction of the sandpaper to prevent the sandpaper from being distorted or deformed.

[0080] As Figure 4As shown, in some embodiments of the present utility model, the shaping mechanism 400 includes a first frame 410, a shaping punch 420, and a shaping disc 430. The first frame 410 is installed on the tabletop of the workbench 100 and has a first mounting plate 411, a second mounting plate 412, and a connecting plate 413. The connecting plate 413 connects the first mounting plate 411 and the second mounting plate 412. The shaping punch 420 is installed on the first mounting plate 411 and is coaxial with the first station 111. The shaping punch 420 and the first station 111 jointly limit the movement mode of the impeller, so that the impeller can only rotate along the axis. The shaping disc 430 is installed on the second mounting plate 412, and the bottom is slightly higher than the first station 111; the shaping disc 430 can reciprocate along the diameter direction of the first turntable 110, and when the shaping disc 430 moves towards the first turntable 110, it can be tangent to the impeller on the first station 111.

[0081] Specifically, when the grinding wheel moves to the lower part of the shaping mechanism 400 along with the first turntable 110, the shaping punch 420 presses down to fix the base body of the grinding wheel. At the same time, the shaping disc 430 approaches the base body to shape the impeller.

[0082] In this embodiment, through the setting of the shaping mechanism 400, the shapes of the produced impellers are kept consistent.

[0083] In some embodiments of the present utility model, the shaping mechanism 400 further includes a shaping cylinder 440. The shaping cylinder 440 is connected to the shaping punch 420 to control the vertical movement of the shaping punch 420.

[0084] In this embodiment, after the formed impeller is transported to the lower part of the shaping punch 420 by the first turntable, the shaping cylinder 440 works to push the shaping punch 420 downward to fix the impeller. At the same time, the shaping disc 430 approaches the impeller to shape the impeller, ensuring that the shapes of all products are kept consistent.

[0085] In some other embodiments of the present utility model, the movement of the shaping disc 430 is completed by the telescoping of a second cylinder. In this embodiment, the second cylinder is connected to the shaping disc 430 to make the shaping disc 430 approach or move away from the center of the first turntable.

[0086] In some embodiments of the present utility model, a guide rail is provided on the connecting plate 413, and the second mounting plate 412 slides along the guide rail to drive the shaping disc 430 to move in the vertical direction.

[0087] In this embodiment, the setting of the guide rail enables the second mounting plate 412 to move in the vertical direction, thereby driving the shaping disc 430 to move in the vertical direction, and enabling the shaping of impellers with different base body heights.

[0088] In some embodiments of the present utility model, the feeding mechanism 600 includes a second turntable 610, a second through rod 612, a feeding guide rail 620, a feeding support 630, a sensing device 640, and a gripper 650. The second turntable 610 is rotatable, and its upper surface is provided with a second working station 611 for placing the substrate. The second through rod 612 is correspondingly arranged with the second working station 611, and the diameter of the second through rod 612 is smaller than the aperture of the through hole, so that the through hole of the substrate can be sleeved on the second through rod 612. The feeding guide rail 620 is vertically arranged beside the second turntable 610, and the sensing device 640 is fixedly installed on the feeding guide rail 620, slightly higher than the upper end surface of the second through rod 612, for detecting whether the substrate reaches a preset position. The feeding support 630 is slidably arranged on the feeding guide rail 620 and has a support plate with a notch. The notch on the support plate is used to accommodate the second through rod 612. The feeding support 630 can move up and down along the feeding guide rail 620 to adjust the vertical height of the substrate sleeved on the second through rod 612. The gripper 650 grabs the substrate from the through rod and places it on the first working station 111.

[0089] The feeding process of this embodiment includes: the through hole of the substrate passes through the second through rod 612, and the substrates are stacked on the first working station 111. After the second turntable 610 rotates by an angle of one working station and aligns with the feeding guide rail 620, the second turntable 610 stops rotating and transmits a signal to the feeding support 630 through a preset program. The feeding support 630 moves upward along the feeding guide rail 620, thereby lifting the substrate upward. After the height of the substrate reaches the position of the sensing device 640, a signal is transmitted to the feeding support 630 to make it stop working. At this time, the gripper 650 grabs the uppermost substrate and transports it to the first working station 111.

[0090] In this embodiment, automatic feeding is realized, and the automation level is improved.

[0091] In the above embodiments, the device elements involved are all conventional device elements unless otherwise specified. The structural setting methods, working methods, or control methods involved are all conventional setting methods, working methods, or control methods in the art unless otherwise specified.

[0092] At this point, those skilled in the art should recognize that although many exemplary embodiments of the present utility model have been shown and described in detail herein, still, without departing from the spirit and scope of the present utility model, many other variations or modifications that conform to the principles of the present utility model can be directly determined or derived from the content disclosed in the present utility model.
