Description

TECHNICAL FIELD

[0001] The utility model relates to a grinding machine technical field especially relates to a drum grinding machine for frame polishing. BACKGROUND

[0002] In the field of glasses manufacturing, the polishing and grinding of frames are crucial links, which directly affect the appearance quality and wearing comfort of glasses. As a common processing equipment, the drum grinding machine for frame polishing places the frame and grinding medium (such as grinding stone, grinding sand, etc.) in the drum, and uses the friction generated by the rotation of the drum to remove the defects on the surface of the frame and achieve polishing.

[0003] However, the current drum grinding machine has many problems of inconvenience and low efficiency in actual operation. After the frame polishing is completed, the glasses and grinding sand need to be discharged from the grinding machine together. Since the glasses and grinding sand are mixed with each other, the glasses must be separated from the grinding sand by means of a subsequent screening process. After screening is completed, the grinding sand needs to be manually poured back into the grinding machine in order to carry out the polishing work of the next batch of frames. This series of operations not only has complicated steps and consumes a lot of manpower and time. Moreover, frequent manual operation is also prone to introduce impurities, which poses a potential threat to the quality of the frame, reduces the production efficiency and increases the production cost. SUMMARY

[0004] The utility model aims to solve at least one of the technical problems in the related art to some extent.

[0005] To this end, the utility model aims to provide a drum grinding machine for frame polishing, which can solve the problems of difficulty in separating grinding sand from glasses and time-consuming and laborious re-pouring into the grinding machine.

[0006] To achieve the above objectives, this utility model proposes a grinding roller for eyeglass frames, comprising a grinding roller and a support frame. A rotating support mechanism is provided on the outer side of the grinding roller. The rotating support mechanism includes two rotating rings and two recessed vertical plates. A material pre-storage box is installed between the two recessed vertical plates. The two rotating rings are rotatably connected to the outer side of the grinding roller, and the recessed vertical plates are installed at one end corresponding to each rotating ring. The material pre-storage box is slidably connected to the outer side of the grinding roller, and a separation mesh plate is slidably connected to the inner wall of the material pre-storage box. A door panel is installed on one side of the material pre-storage box. Two limiting rings are installed on the side wall of the grinding roller. Both limiting rings are rotatably connected to the inner wall of the corresponding rotating ring. Limiting holes are opened at the bottom of the limiting rings. Electrically controlled telescopic rods are installed on the inner sides of the two recessed vertical plates. The output end of the electrically controlled telescopic rod is inserted into the inner wall of the corresponding limiting hole. A material inlet and outlet are opened at the bottom of the grinding roller. The material inlet and outlet are located at the opening position of the material pre-storage box. An L-shaped sealing plate is slidably connected to the inner wall of the material inlet and outlet. The L-shaped sealing plate does not contact the support frame.

[0007] This utility model relates to a roller grinding machine for eyeglass frames. By connecting and separating an electrically controlled telescopic rod and a limiting insertion hole, the grinding roller can be rotated to drive the material pre-storage box to be fed into the grinding roller when the grinding sand is introduced into the grinding roller. This eliminates the need for personnel to lift and feed the sand in, solving the problems that not only are the operation steps cumbersome and consume a lot of manpower and time, but frequent manual operation can also easily introduce impurities, posing a potential threat to the quality of the eyeglass frames, reducing production efficiency and increasing production costs.

[0008] In addition, the tumbler polishing machine for eyeglass frames proposed above according to this utility model may also have the following additional technical features:

[0009] Specifically, both ends of the separating mesh plate are fixedly connected to extension plates, and the two extension plates pass through one side of the corresponding recessed vertical plate. A limiting plate is installed at one end of each of the two extension plates. A drive motor is installed on the inner wall of one of the recessed vertical plates, and a cam is installed at the output end of the drive motor. The cam is slidably connected to one side of the corresponding limiting plate.

[0010] Specifically, baffles are fixedly connected to the inner walls of both recessed vertical plates, the cam does not contact the corresponding baffle, and a first return spring is installed between the other baffle and the corresponding extension plate.

[0011] Specifically, a handle is slidably connected to one side of the L-shaped sealing plate, a limit plate is fixedly connected to the top of the handle, a limit plate is installed on one side of the grinding roller, and the limit plate is inserted into the inner wall of the limit plate.

[0012] Specifically, a fixing block is fixedly connected to one side of the L-shaped sealing plate, and a second return spring is installed between the fixing block and the handle.

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0024] The following description, in conjunction with the accompanying drawings, describes a roller grinding machine for polishing eyeglass frames according to an embodiment of the present invention.

[0025] like Figures 1-6 As shown, a roller grinding machine for grinding eyeglass frames according to an embodiment of the present invention may include a grinding roller 1 and a support frame 11. A rotating support mechanism 2 is provided on the outside of the grinding roller 1. The rotating support mechanism 2 includes two rotating rings 21 and two recessed vertical plates 22. A material distribution pre-storage box 3 is installed between the two recessed vertical plates 22.

[0026] Two rotating rings 21 are rotatably connected to the outside of the grinding drum 1, a recessed vertical plate 22 is installed at one end of the corresponding rotating ring 21, and a material pre-storage box 3 is slidably connected to the outside of the grinding drum 1.

[0027] It should be noted that the rotating support mechanism 2 and the material pre-storage box 3 described in this embodiment both have the grinding roller 1 as the rotation axis.

[0028] Among them, a separation mesh plate 31 is slidably connected to the inner wall of the material distribution pre-storage box 3, and a door panel 32 is installed on one side of the material distribution pre-storage box 3.

[0029] It should be noted that the width of the separating mesh plate 31 described in this embodiment is adapted to the inner diameter of the material pre-storage box 3.

[0030] Two limiting rings 12 are installed on the side wall of the grinding roller 1. Both limiting rings 12 are rotatably connected to the inner wall of the corresponding rotating ring 21. A limiting insertion hole 121 is opened at the bottom of the limiting ring 12. An electrically controlled telescopic rod 23 is installed on the inner side of the two recessed vertical plates 22. The output end of the electrically controlled telescopic rod 23 is inserted into the inner wall of the corresponding limiting insertion hole 121.

[0031] It should be noted that the rotating ring 21 described in this embodiment encloses the corresponding limiting ring 12.

[0032] The grinding roller 1 has a feed inlet / discharge port 13 at the bottom, which corresponds to the opening of the pre-storage box 3. An L-shaped sealing plate 4 is slidably connected to the inner wall of the feed inlet / discharge port 13, and the L-shaped sealing plate 4 does not contact the support frame 11.

[0033] It should be noted that the feed inlet / outlet 13 described in this embodiment is at a corresponding angle to the two limiting holes 121.

[0034] Specifically, to solve the problems of difficulty in separating the abrasive from the eyeglasses and the time-consuming and laborious process of refilling it into the grinding machine, the grinding roller 1 is driven to rotate by the external drive device of the support frame 11. The grinding roller 1 drives the internal abrasive and eyeglasses to rotate, allowing the eyeglasses to be polished by the abrasive, thus completing the processing of the eyeglasses. The grinding roller 1 is limited by two limiting rings 12 to limit the two rotating rings 21, preventing lateral positional changes and separation between the rotating support mechanism 2 and the grinding roller 1. The rotating rings 21 are positioned relative to the concave vertical plate 22. The recessed vertical plate 22 is used for support and rotation adjustment. The electrically controlled telescopic rod 23 unlocks and locks the limiting insertion hole 121. When the grinding roller 1 rotates during grinding, the electrically controlled telescopic rod 23 is not connected to the limiting insertion hole 121. The locking mechanism provides auxiliary fixation to the material pre-storage box 3 or the recessed vertical plate 22 to maintain stability. The rotation of the grinding roller 1 will not drive the rotation support mechanism 2 or the material pre-storage box 3 to rotate. After grinding, the inlet / outlet 13 faces downwards and aligns with the material pre-storage box 3. The electrically controlled telescopic rod 23 then... At this time, rod 23 is inserted into the limiting socket 121 to lock the rotating support mechanism 2 and the grinding roller 1. The inlet and outlet 13 is opened by sliding the L-shaped sealing plate 4, so that the grinding sand and eyeglass material in the grinding roller 1 can be discharged into the pre-storage box 3. The pre-storage box 3 separates the two by the mechanical reciprocating sliding of the separating mesh plate 31. The separated eyeglasses are taken out through the door plate 32, and new eyeglasses to be processed are placed. By rotating the grinding roller 1, the electrically controlled telescopic rod 23 is locked with the limiting socket 121. In this state, the rotating ring 21 and the recessed vertical plate 22 can rotate upwards, allowing the grinding sand in the pre-storage box 3 to flow back into the grinding drum 1 for use. This solves the problems that not only is the operation cumbersome and consumes a lot of manpower and time, but frequent manual operation can also easily introduce impurities, posing a potential threat to the quality of the frame, reducing production efficiency and increasing production costs. Afterwards, the recessed vertical plate 22 and the pre-storage box 3 are sent back to the position below the grinding drum 1, and then the L-shaped sealing plate 4 is inserted back in to restart the processing of a new batch.

[0035] In one embodiment of this utility model, such as Figures 1-6 As shown, extension plates 311 are fixedly connected to both ends of the separation mesh plate 31. The two extension plates 311 pass through one side of the corresponding recessed vertical plate 22. A limit plate 312 is installed at one end of each of the two extension plates 311. A drive motor 24 is installed on the inner wall of one of the recessed vertical plates 22. A cam 241 is installed at the output end of the drive motor 24. The cam 241 is slidably connected to one side of the corresponding limit plate 312.

[0036] It should be noted that the separation mesh plate 31 described in this embodiment extends into the recessed vertical plate 22 via the extension plate 311.

[0037] Specifically, the extension plate 311, the limiting plate 312, and the drive motor 24 are all located in the recessed space of the corresponding recessed vertical plate 22. By controlling the drive motor 24 to drive the cam 241 to rotate, the limiting plate 312 is repeatedly moved, so that the pre-storage box 3 can mechanically reciprocate and shake to complete the separation of the glasses and the grinding sand.

[0038] In one embodiment of this utility model, such as Figures 1-6 As shown, baffles 221 are fixedly connected to the inner walls of the two recessed vertical plates 22. The cam 241 does not contact the corresponding baffle 221. A first return spring 25 is installed between the other baffle 221 and the corresponding extension plate 311.

[0039] It should be noted that the positions of the first reset spring 25 and the cam 241 described in this embodiment are symmetrically distributed.

[0040] Specifically, when the cam 241 pushes the limiting disk 312, the first return spring 25 is compressed. When the narrow end of the cam 241 contacts the limiting disk 312, the first return spring 25 can push the corresponding limiting disk 312, so that the separating mesh plate 31 can stably perform reciprocating sliding operation.

[0041] In one embodiment of this utility model, such as Figures 1-6 As shown, a handle 41 is slidably connected to one side of the L-shaped sealing plate 4, and a limit plate 411 is fixedly connected to the top of the handle 41. A limit plate 14 is installed on one side of the grinding roller 1, and the limit plate 411 is inserted into the inner wall of the limit plate 14.

[0042] It should be noted that the bottom of the limiting plate 14 described in this embodiment has a slot corresponding to the limiting insert plate 411.

[0043] Specifically, when the L-shaped sealing plate 4 is inserted back, it can block the inlet and outlet ports 13 to prevent the grinding sand and eyeglasses inside the grinding roller 1 from being discharged. The handle 41 makes it easy for the operator to control the L-shaped sealing plate 4. By pulling the handle 41, the limiting plate 411 can be removed from the limiting plate 14, thus unlocking the L-shaped sealing plate 4 and facilitating the subsequent opening of the inlet and outlet ports 13.

[0044] In one embodiment of this utility model, such as Figures 1-6 As shown, a fixing block 42 is fixedly connected to one side of the L-shaped sealing plate 4, and a second reset spring 43 is installed between the fixing block 42 and the handle 41.

[0045] It should be noted that the fixing block 42 described in this embodiment pushes the handle 41 toward the limiting plate 14 by the second reset spring 43.

[0046] Specifically, the L-shaped sealing plate 4 supports the fixing block 42, and the fixing block 42 pushes the handle 41 elastically through the second reset spring 43, so that the handle 41 can stably drive the limiting insert plate 411 to dock with the limiting plate 14, preventing the L-shaped sealing plate 4 from being accidentally unlocked.

[0047] In summary, in the tumbling grinding machine for eyeglass frames of this embodiment, after the grinding of the eyeglasses in the grinding drum 1 is completed, the grinding drum 1 stops rotating. The inlet / outlet 13 is aligned with the top opening of the pre-storage box 3 via a positioning mechanism. At this time, the electrically controlled telescopic rod 23 is inserted into the limiting hole 121 to lock the rotating support mechanism 2 and the grinding drum 1. By pulling the handle 41, the limiting plate 411 is separated from the limiting plate 14. By pulling the L-shaped sealing plate 4, the inlet / outlet 13 is opened, allowing both the grinding sand and eyeglass material in the grinding drum 1 to be discharged into the pre-storage box 3. The repeated pushing of the two limiting discs 312 by the cam 241 and the first return spring 25 causes the mechanical reciprocating sliding of the separating mesh plate 31 to achieve the alignment of the two discs. The process involves separating the glasses, removing them through the door panel 32, and placing new glasses to be processed. By rotating the grinding roller 1, with the electrically controlled telescopic rod 23 locked to the limit socket 121, the rotating ring 21 and the recessed vertical plate 22 can rotate upwards, allowing the grinding sand in the pre-storage box 3 to flow back into the grinding roller 1 for use. This solves the problems of cumbersome operation, high manpower and time consumption, frequent manual operation, and the potential introduction of impurities that threaten the quality of the frames, reduce production efficiency, and increase production costs. Afterwards, the recessed vertical plate 22 and the pre-storage box 3 are returned to the position below the grinding roller 1, and then the L-shaped sealing plate 4 is inserted to restart the processing of a new batch.

[0048] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
