[0032] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

Therefore, it should not be construed as a limitation of this utility model.

[0034] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0035] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0036] See Figure 1 , Figure 2 , Figure 5 , Figure 8 An embodiment of this utility model provides an end face grinding device, including a material loading mechanism 100, a material pressing mechanism 200, a feeding mechanism 300, and a grinding mechanism 400. The material loading mechanism 100 includes a material loading disk 101, which is configured to rotate around an axis. The outer circumferential surface of the material loading disk 101 is provided with a plurality of circumferentially distributed material loading grooves 102. The openings of the material loading grooves 102 face the radially outer side of the material loading disk 101. The material loading grooves 102 are used to place the product 500 to be ground (e.g., a ceramic insert) therein, so that it can further contact the grinding mechanism 400 during the rotation of the material loading disk 101 to complete the grinding.

[0037] See Figure 1 , Figure 4The pressing mechanism 200 includes a pressing belt 201 and a belt tensioning mechanism. The belt tensioning mechanism includes multiple pulleys. The pressing belt 201 passes over the multiple pulleys and the material tray 101. The belt tensioning mechanism tensions the pressing belt 201 and causes the pressing belt 201 to be sleeved on a portion of the outer peripheral surface of the material tray 101. The pressing belt 201 is used to confine the product 500 in the material trough 102 in the area where it is sleeved with the material tray 101. In other words, the pressing belt 201 is not sleeved on the entire outer peripheral surface of the material tray 101, but rather at a certain position in the rotation direction of the material tray 101, the pressing belt 201 engages with the material tray 101. At a certain position in the rotation direction of the material tray 101, the pressing belt 201 separates from the material tray 101, thus forming the pressing belt 201 sleeved on a portion of the outer peripheral surface of the material tray 101. The area where the pressure belt 201 and the loading tray 101 enter the sleeve engagement can be provided with a feeding area, which is used to put the product 500 into the loading trough 102 before the pressure belt 201 and the loading tray 101 enter the sleeve engagement; the area where the pressure belt 201 and the loading tray 101 separate can be provided with a discharging area, which is used to remove the ground product 500 from the loading tray 101 after the pressure belt 201 and the loading tray 101 separate.

[0038] See Figure 1 , Figure 3 The feeding mechanism 300 is used to feed the product 500 into the loading trough 102 in the area where the pressure belt 201 and the loading tray 101 are not connected.

[0039] join Figure 1 , Figure 5 The grinding mechanism 400 includes a grinding wheel 401 and a first driving mechanism 402. The friction surface of the grinding wheel 401 overlaps with the rotation path of the material tray 101. The first driving mechanism 402 drives the grinding wheel 401 to rotate in order to grind the product 500 in the material tray 102 that rotates to the friction surface of the grinding wheel 401.

[0040] See Figure 1 , Figure 2 , Figure 5 , Figure 8The technical solution of this utility model can be used for end face grinding of ceramic inserts. During the grinding process, the feeding mechanism 300 feeds the product 500 into the loading groove 102 of the loading tray 101 in the area where the pressure belt 201 and the loading tray 101 are not connected (feeding area), so that the end face of the ceramic insert faces outward. As the loading tray 101 rotates, the pressure belt 201 is sleeved on the outer circumference of the loading tray 101, pressing and confining the product 500 in the loading groove 102. The loading tray 101 continues to rotate and passes through the area of ​​the grinding wheel 401. The grinding wheel 401 rotates at high speed and grinds the end face of the product 500 fixed in the loading groove 102. After passing through the area of ​​the grinding wheel 401, the product 500 is ground, and the pressure belt 201 separates from the loading tray 101, releasing the product 500 from the loading groove 102. The technical solution of this utility model has higher processing efficiency, more reliable quality, and improves processing efficiency and accuracy.

[0041] In some embodiments, see Figure 1 , Figure 4 The belt tensioning mechanism also includes a cylinder 202. The pulleys include a movable pulley 203 and a fixed pulley 204. The fixed pulley 204 is fixedly installed on the body of the end face grinding device. The movable pulley 203 is driven by the cylinder. The pressure belt 201 is tensioned under the action of the movable pulley 203 and the fixed pulley 204. The pressure belt 201 is guided to fit onto part of the outer peripheral surface of the material tray 101.

[0042] In some embodiments, see Figure 2 , Figure 3 The feeding mechanism 300 includes a feeding block 301, which has an inlet 302 and an outlet 303. A feeding channel is formed between the inlet 302 and the outlet 303, extending from the inlet 302 to the outlet 303. During operation, the product 500 is introduced into the feeding channel through the inlet 302 and then guided one by one along the feeding channel to the outlet 303. By setting the inlet 302, the feeding channel, and the outlet 303, it is ensured that the product 500 can be continuously fed into the loading trough 102 of the loading tray 101 in the feeding area with its end face facing outward.

[0043] In some embodiments, see Figure 3The feeding mechanism 300 includes a second drive mechanism 304, which can be fixedly installed on the body of the end face grinding device. The second drive mechanism 304 is used to drive the feeding block 301 to move so that the feeding port 302 approaches or moves away from the material loading groove 102 of the material loading tray 101. The second drive mechanism 304 can be a cylinder, an electric push rod, or a synchronous belt pulley mechanism. During operation, when the feeding block 301 needs to be fed, the second drive mechanism 304 drives the feeding block 301 to approach the material loading tray 101 along the axial direction of the material loading tray 101, and the discharge port 303 of the feeding block 301 is aligned with the material loading groove 102 of the material loading tray 101. The product 500 is output from the discharge port 303 and enters the material loading groove 102 of the material loading tray 101. After feeding is completed, the second drive mechanism 304 drives the feeding block 301 to move away from the material loading tray 101 along the axial direction of the material loading tray 101.

[0044] Further, see Figure 3 The feeding block 301 is provided with a pressure rod hole, which extends from the side, for example, the top of the feeding block 301, to the feeding channel. The feeding mechanism 300 also includes a pressure rod 305 and a third drive mechanism 306. The pressure rod 305 is provided in the pressure rod hole, and the third drive mechanism 306 is used to drive the pressure rod 305 to move along the pressure rod hole to press or release the product 500 in the feeding channel. The third drive mechanism 306 can be a cylinder, an electric push rod, etc. The feeding block 301 is provided with a blowing port 307 that communicates with the feeding channel. When it is necessary to output the product 500 in the feed block 301 from the discharge port 303 and enter the loading trough 102 of the loading tray 101, the third drive mechanism 306 drives the pressure rod to move along the pressure rod hole to release the product 500 in the feed channel. Airflow is blown into the feed channel through the blowing port 307. Under the action of the airflow, the product 500 in the feed channel is output from the discharge port 303 and enters the loading trough 102 of the loading tray 101. This embodiment adopts the air blowing method, combined with the feed channel inside the feed block 301, which can easily realize the conveying and feeding of the product 500.

[0045] In some embodiments, see Figure 1 , Figure 6 The end face grinding device also includes a feeding mechanism 600, which includes a vibratory plate 601 and a feeding pipe 602. The feeding pipe 602 extends from the vibratory plate 601 to the feed inlet 302 of the feed block 301. The feeding pipe 602 can be configured to have a certain slope. Under the vibration of the vibratory plate 601, the product 500 in the vibratory plate 601 is automatically conveyed to the feed inlet 302 of the feed block 301 along the feeding pipe 602, thereby realizing automatic feeding.

[0046] The feeding tube 602 can be made of plastic or metal. In some embodiments, the feeding tube 602 includes a feeding spring tube, which has higher wear resistance than plastic tube. At the same time, the feeding spring tube has good elasticity and deformation ability, which makes it easier to connect between the vibratory plate 601 and the feed block 301 and can adapt to the reciprocating feeding action of the feed block 301.

[0047] In some embodiments, see Figure 6 , Figure 7 The vibratory feeder 601 has an outer peripheral wall 603 extending along the height direction. The outer peripheral wall 603 has a certain height. The outer wall surface of the outer peripheral wall 603 is provided with a material channel extending circumferentially along the outer peripheral wall 603. The material channel extends a certain width from the outer wall surface of the outer peripheral wall 603. The product 500 can be conveyed one by one along the material channel under the vibration of the vibratory feeder 601.

[0048] The material conveying system includes a primary material conveying channel 604, a secondary material conveying channel 605, and a tertiary material conveying channel 609 arranged sequentially along the conveying direction. A first ramp 606 is provided between the primary and secondary material conveying channels 604 and 605 to allow the conveyed product 500 to stand upright. A notch 607 is provided on the outer peripheral wall 603 at the position corresponding to the secondary material conveying channel 605 for products 500 that are not upright to fall into the vibrating plate 601. A second ramp 610 is provided between the secondary and tertiary material conveying channels 605 and 609. A feeding pipe 602 is connected to the tertiary material conveying channel 609. During operation, the product 500 is first conveyed along the primary material conveying channel 604. At this time, the end orientation of the product 500 is not uniform; some products 500 have their larger diameter end facing forward, while others have their smaller diameter end facing forward. When grinding is required on one end, the products 500 need to be aligned to the same direction so that the feeding mechanism can sequentially feed the products 500 into the loading trough in the same direction. Specifically, when product 500 enters the first ramp 606 from the primary feed channel 604, because the slope of the first ramp 606 is significantly greater than that of the primary feed channel 604, product 500 will be erected along the first ramp 606. Products 500 with the larger diameter end facing forward can stand stably and continue to be conveyed along the secondary feed channel 605, while products 500 with the smaller diameter end facing forward cannot be erected and thus fall into the vibrating plate 601 through the gap 607. When product 500 continues to be conveyed along the secondary feed channel 605 and enters the second ramp 610, because the slope of the second ramp 610 is significantly greater than that of the secondary feed channel 605, product 500 will be laid down along the second ramp 610 and continue to be conveyed in a lying position along the tertiary feed channel 609. This embodiment cleverly achieves uniformity in the conveying posture of product 500 through the above structural design, ensuring that all products 500 fed into the feed block 301 through the feed pipe 602 have a uniform orientation.

[0049] In this invention, when the product 500 of the secondary feed channel 605 passes through the second ramp 610, the end with the smaller diameter tilts forward, so that it can continue to be conveyed along the tertiary feed channel 609 with the end with the smaller diameter facing forward.

[0050] In some embodiments, see Figure 7 The vibratory feeder 601 has a first feeding component 608 at the end of the notch 607, which tilts the upright products backward from the top. The first feeding component 608 is located above the secondary feed channel 605. In this embodiment, when the product 500 in the secondary feed channel 605 reaches the position of the first feeding component 608, its top is blocked by the first feeding component 608, and the smaller diameter end tilts backward, so that it can continue to be conveyed forward along the tertiary feed channel 609 with the larger diameter end.

[0051] In the embodiments of this utility model, the conveying direction of the product 500 along the material channel can be flexibly controlled by setting or canceling the first feeding component 608.

[0052] In some embodiments, see Figure 2 , Figure 8 The material loading mechanism 100 also includes a baffle plate 103, which is disposed on the back side of the material loading plate 101 and is fixedly connected to the material loading plate 101. The edge of the baffle plate 103 protrudes radially from the material loading plate 101, and the baffle plate 103 has a baffle post 104 at the position corresponding to the material loading groove 102. In this embodiment, by setting the baffle plate 103 and the baffle post 104, the product 500 can be pressed against the material loading groove 102 from the opposite direction of the end face of the product 500 being ground. This, combined with the groove wall of the material loading groove 102 and the pressure belt 201, fixes the swing of the product 500 in various directions.

[0053] In some embodiments, see Figure 2 , Figure 8 The cross-section of the material loading trough 102 is V-shaped. The V-shaped cross-section of the material loading trough 102 enables the product 500 in the material loading trough 102 to be more stable under the radial tightening action of the pressure belt 201.

[0054] Multiple material loading grooves 102 form a toothed structure on the outer periphery of the material loading disk 101. The multiple material loading grooves 102 are closely arranged, which can improve the material loading capacity of the material loading disk 101 and improve the grinding efficiency of product 500. The toothed structure is provided with radially extending side flanges 105, which can cooperate with the pressure belt 201 to prevent the pressure belt 201 from detaching from the material loading disk 101.

[0055] In some embodiments, see Figure 1 The end face grinding device also includes a fourth drive mechanism 700, which drives the material carrier 101 to rotate around the axis.

[0056] See Figure 1 , Figure 9 Below the starting point of the separation between the pressure belt 201 and the loading tray 101, there is a receiving component 801. Above the receiving component 801, there is a second pushing component 802 for pushing the product 500 out of the loading trough 102. The second pushing component 802 can prevent the product 500 in the loading trough 102 from being unable to separate from the loading tray 101.

[0057] The working principle of some embodiments of this utility model is as follows:

[0058] The vibratory feeder 601 feeds product 500 through the feeding spring tube to the feed port 302 of the feeding mechanism 300. The second drive mechanism 304 moves forward, and the pressure rod is released by the third drive mechanism 306. Air enters through the blowing port 307, blowing product 500 from the discharge port 303 into the V-groove of the carrying tray 101. Product 500 is placed in the V-groove and its left and right positions are restricted. The pressure belt then presses down on product 500. The baffle post 104 in the baffle plate 103 restricts the forward direction of product 500, thus fixing the swing of product 500 in all directions. The baffle post 104 is installed on the baffle plate 103 and rotates together with the baffle plate 103 and the carrying tray 101. The cylinder in the belt tensioning mechanism is always in the retracted state, the pressure belt is tensioned, and the carrying tray 101 is driven to rotate by an internal motor. When it rotates to a certain angle, product 500 is pressed down. Next, the product 500 is carried by the material carrier 101 through the area of ​​the grinding wheel 401. The grinding wheel 401 rotates at high speed to grind the end face of the product 500. Figure 5 As shown. After passing through the grinding wheel 401 area, product 500 also completes grinding. In the feeding area, as the pressure belt 201 is released, product 500 automatically falls into the lower receiving box, thus completing one grinding process. Each of the above actions is performed continuously, thereby achieving a continuous grinding effect.
