Description

Technical Field

[0001] The invention belongs to the technical field of refrigerator accessory production and relates to a refrigerator glass partition edge grinding device. Background Art

[0002] There should be a certain amount of space between the food in the refrigerator. The food should not be placed close to the left, right and back walls of the refrigerator to allow for cold air convection. The refrigerator should not be too full. The refrigerator glass partition plays the role of isolating food and can improve the space utilization rate inside the refrigerator. When producing the refrigerator glass partition, the edges of the cut glass need to be polished to prevent scratches on users and improve the appearance.

[0003] When grinding the edges of refrigerator glass partitions, the existing grinding device requires the operator to accurately place the glass cover on the adsorption plate, then fix the refrigerator glass partition by negative pressure, and then grind the edges of the refrigerator glass partition by the grinding head. Each time grinding is performed, the operator needs to load and unload the material, and continuous grinding cannot be performed. It takes a long time and has a low degree of automation, resulting in low grinding efficiency for the refrigerator glass partition.

[0004] Based on this, we designed a refrigerator glass partition edge grinding device. Summary of the Invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a refrigerator glass partition edge grinding device. The technical problem to be solved by the device is: how to continuously grind the refrigerator glass cover and improve the grinding efficiency.

[0006] The purpose of the present invention can be achieved through the following technical solutions:

[0007] A device for grinding the edges of refrigerator glass partitions comprises a support frame, a frame being fixed on the support frame, a conveyor belt and a drive motor for driving the conveyor belt being provided on the frame, a plurality of adjustable bases for placing refrigerator glass partitions being provided on the conveyor belt, and the plurality of adjustable bases being distributed at equal intervals, a clamping mechanism for clamping the refrigerator glass partitions being provided above the conveyor belt, two correction mechanisms and two grinding mechanisms being provided on the frame, and the correction mechanisms and the grinding mechanisms being distributed alternately, a support plate being fixed on the inner side of the frame, and a strip groove being provided on the support plate, a limiting mechanism for fixing the adjustable base being provided on the inner side of the frame, the limiting mechanism comprising a plurality of rotating sleeves, and a rotating mechanism for controlling the rotation of the rotating sleeve being provided inside the rotating sleeve.

[0008] The working principle of the present invention is as follows: when in use, the operator places the refrigerator glass partition on one of the adjustable bases. As the conveyor belt runs, the refrigerator glass partition moves to the bottom of the pressing mechanism and is pressed on the adjustable base by the pressing mechanism. Afterwards, the refrigerator glass partition follows the conveyor belt through the correction mechanism, and the position of the refrigerator glass partition is adjusted by the correction mechanism. After the adjustment is completed, the adjustable base is locked by the limit mechanism to prevent the refrigerator glass partition from shaking. Then, as the conveyor belt runs, the refrigerator glass partition passes through the polishing mechanism, and the polishing mechanism polishes both sides of the refrigerator glass partition. After the polishing is completed, the rotating mechanism drives the refrigerator glass partition to rotate 90°, and then passes through another correction mechanism and another polishing mechanism again, so that the four edges of the refrigerator glass partition can be fully polished. Finally, as the conveyor belt runs, the refrigerator glass partition moves out of the pressing mechanism, and the operator can remove the polished refrigerator glass partition from the other end of the conveyor belt, thereby realizing continuous polishing of the refrigerator glass partition, improving the degree of automation, and improving the polishing efficiency.

[0009] The clamping mechanism includes several connecting frames fixed on the frame, the connecting frames are fixed with mounting frames, the mounting frames are provided with a synchronous belt and a synchronous motor for driving the synchronous belt, the synchronous belt is provided with several equally spaced clamping components, and the spacing between the clamping components is equal to the spacing between the adjustable bases, the clamping components include several fixing seats fixed on the synchronous belt, and the fixing seats are provided with mounting holes, and squeezing balls are provided in the mounting holes.

[0010] With the above structure, the synchronous motor drives the synchronous belt to run at the same speed as the conveyor belt, so that the clamping assembly is aligned with the adjustable base at the corresponding position. When the refrigerator glass partition follows the conveyor belt and moves under the synchronous belt, the squeezing ball in the clamping assembly will press on the top of the refrigerator glass partition, pressing the refrigerator glass partition onto the adjustable base. Moreover, when the position of the refrigerator glass partition is adjusted, the squeezing ball can roll in the mounting hole without hindering the movement and rotation of the refrigerator glass partition.

[0011] The correction mechanism includes a support base symmetrically fixed on both sides of the frame, a mounting base fixed on the support base, a push rod motor installed on the mounting base, and a correction frame fixed on the output shaft of the push rod motor, and a driven belt installed on the correction frame.

[0012] With the above structure, when the refrigerator glass partition moves to the middle of the two correction frames, the two push rod motors drive the two correction frames to move closer to the middle, pushing the refrigerator glass partition located on the adjustable base toward the middle, so that the edge positions on both sides of the refrigerator glass partition can match the polishing mechanism. The operator does not need to perform precise positioning, making the operation more convenient. Moreover, when the two driven belts clamp and absorb the glass partition, the driven belts can rotate and will not hinder the movement of the refrigerator glass partition.

[0013] The grinding mechanism includes a support base fixed on both sides of the frame and two grinding motors. The support base is provided with an installation slot and a long through-hole. The grinding motor is fixed to the support base through bolts and the installation slot. The output shaft of the grinding motor passes through the long through-hole, and a grinding wheel is fixed at its end.

[0014] With the above structure, when in use, when the refrigerator glass partition passes between the two grinding wheels, the grinding motor drives the grinding wheels to rotate to grind both sides of the refrigerator glass partition, and the position of the grinding motor can be moved, so that the equipment can grind refrigerator glass partitions of different sizes.

[0015] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0016] With the above structure, when the operator places the refrigerator glass partition on the placement seat, the refrigerator glass partition is initially fixed by the suction cup, and the transverse plate can slide along the sliding seat, and the placement seat is rotatably connected to the transverse plate, so that the refrigerator glass partition can rotate.

[0017] The limiting mechanism also includes a built-in conveyor belt arranged on the frame, a limiting motor for driving the built-in conveyor belt is installed on the outside of the frame, a rotating sleeve is rotatably arranged on the built-in conveyor belt, several rotating sleeves are distributed at equal intervals, and the spacing between the rotating sleeves is equal to the spacing between the adjustable bases, the built-in conveyor belt is located directly below the strip groove, a first lifting ring is provided on the rotating sleeve, and several damping sliders are fixed on the inner side of the first lifting ring, several sliding grooves are opened on the outside of the rotating sleeve, and the damping slider is slidably arranged in the sliding groove, a thrust spring is provided in the sliding groove, and the two ends of the thrust spring are respectively against the bottom inner wall of the sliding groove and the damping slider, and four triangular blocks distributed at equal intervals are fixed above the first lifting ring.

[0018] When the movable base is moved to the position above the conveyor belt, the movable base is pressed against the lower surface of the movable plate, thereby limiting the rotation of the movable plate. Since the movable plate and the rotating shaft are connected by a universal joint and a telescopic sleeve, the movable plate and the rotating shaft can only rotate synchronously. When the rotation of the movable plate is restricted, the rotating shaft and the placement seat cannot continue to rotate. At this time, the first lifting ring will press against the extrusion block, pushing the lifting rod upward, so that the upper end of the lifting rod presses against the anti-slip pad, limiting the sliding of the transverse plate, and then positioning the refrigerator glass partition on the placement seat to prevent it from shaking during polishing and improving the polishing quality.

[0019] The rotating mechanism includes a fixed shaft fixed on the built-in conveyor belt, the bottom of the fixed shaft is sleeved with a bearing, the rotating sleeve is sleeved on the outside of the fixed shaft, and the inner wall of the rotating sleeve is fixed to the outer ring of the bearing, four equally spaced protrusions are provided on the outside of the fixed shaft, and one side of the protrusion is provided with a chamfer, a second lifting ring and a return spring are sleeved on the fixed shaft, and the two ends of the return spring are respectively against the inner wall of the rotating sleeve and the second lifting ring, four equally spaced extension rods are fixed below the second lifting ring, and the extension rods and the protrusions are distributed alternately, four long slots are opened on the side wall of the rotating sleeve, and the ends of the extension rods pass through the long slots at corresponding positions, and a bent rod is fixed on the inner wall of the strip groove.

[0020] With the above structure, when in use, the fixed shaft moves with the built-in conveyor belt. When the fixed shaft passes through the bent rod, one of the extension rods is squeezed upward by the bent rod and moves upward along the long slot, driving the second lifting ring to move upward and compressing the reset spring. When the extension rod moves above the protrusion, the extension rod is affected by the upper end of the bent rod and cannot move synchronously with the fixed shaft. At this time, the extension rod will drive the rotating sleeve to rotate. After rotating a certain angle, the extension rod passes the bent rod. At this time, under the action of the reset spring, the extension rod slides downward along the chamfer and slides into the gap between the other protrusions. At this time, the rotating sleeve rotates exactly 90°, and the rotation of the rotating sleeve will drive the rotating plate to rotate synchronously. The joint and the telescopic sleeve drive the rotating shaft and the placement seat to rotate 90°, thereby driving the refrigerator glass partition to rotate 90°. In addition, when the rotating sleeve rotates, the first lifting ring will also rotate synchronously, and while the first lifting ring rotates, the triangular block and the extrusion block will resist each other, pushing the first lifting ring downward and compressing the thrust spring. When the triangular block passes the extrusion block, the thrust spring drives the first lifting ring to move upward. Under the action of the damping slider, the first lifting ring moves slowly. At this time, the lifting rod cannot be supported by the first lifting ring and separates from the anti-slip pad. During the slow rise of the first lifting ring, the transverse plate can slide on the sliding seat, so that the refrigerator glass partition can be adjusted again by the correction mechanism after rotating 90°.

[0021] Compared with the existing technology, the refrigerator glass partition edge grinding device has the following advantages:

[0022] 1. The refrigerator glass partition placed on the adjustable base can be automatically transported by the conveyor belt, the adjustable base and the pressing mechanism, the refrigerator glass partition is positioned on both sides by the correction mechanism, and the refrigerator glass partition is polished on both sides by the polishing mechanism, thereby realizing continuous automatic polishing, improving the degree of automation, and improving the polishing efficiency of the refrigerator glass partition.

[0023] 2. The direction of the refrigerator glass partition is automatically adjusted through the rotating mechanism, and the other two sides of the refrigerator glass partition are polished. The operator does not need to reload the material, which further improves the polishing efficiency.

[0024] 3. The limiting mechanism can fix the refrigerator glass partition during grinding to prevent it from shaking during the grinding process, thereby improving the grinding quality. It does not affect the correction mechanism to adjust the position of the refrigerator glass partition, and does not require manual operation by the operator, further improving the degree of automation of the equipment.

[0049] Working principle of the present invention:

[0050] When in use, when the operator places the refrigerator glass partition on the seat 504, the refrigerator glass partition is initially fixed by the suction cup 505, and the transverse plate 502 can slide along the sliding seat 501, and the placement seat 504 is rotatably connected to the transverse plate 502, so that the refrigerator glass partition can rotate. As the conveyor belt 3 runs, the refrigerator glass partition moves to the bottom of the synchronous belt 603, and the squeezing ball 606 will press on the top of the refrigerator glass partition, pressing the refrigerator glass partition on the adjustable base 5, and when adjusting the position of the refrigerator glass partition, the squeezing ball 606 can roll in the mounting hole and will not hinder the movement and rotation of the refrigerator glass partition. Afterwards, the refrigerator glass partition follows the conveyor belt 3 through the correction mechanism 7. At this time, the two push rod motors 703 drive The two correction frames 704 are moved closer to the middle, and the refrigerator glass partition on the adjustable base 5 is pushed toward the middle. After the adjustment is completed, when the adjustable base 5 moves to above the built-in conveyor belt 901, the rotating sleeve 903 at the corresponding position passes through the strip groove 11 and the through hole 301 at the corresponding position, and the upper surface of the rotating sleeve 903 is abutted against the lower surface of the rotating plate 509, limiting the rotation of the rotating plate 509. Since the rotating plate 509 is connected to the rotating shaft 503 through the universal joint 508 and the telescopic sleeve rod 507, the rotating plate 509 and the rotating shaft 503 can only rotate synchronously. When the rotation of the rotating plate 509 is restricted, the rotating shaft 503 and the placement seat 504 can no longer rotate, and at this time the first lifting ring 904 will abut against the extrusion block 512, lifting the The lowering rod 510 is pushed upward, so that the upper end of the lifting rod 510 is against the anti-slip pad 511, which limits the sliding of the transverse plate 502, and then positions the refrigerator glass partition on the placement seat 504 to prevent the refrigerator glass partition from shaking. Then, as the conveyor belt 3 runs, the refrigerator glass partition passes through the grinding mechanism 8. At this time, the grinding motor 804 drives the grinding wheel 805 to rotate to grind both sides of the refrigerator glass partition. After the grinding is completed, when the fixed shaft 1201 passes through the bent rod 13, one of the extension rods 1206 is squeezed upward by the bent rod 13 and moves upward along the long slot 908, driving the second lifting ring 1205 to move upward and compressing the reset spring 1207. When the extension rod 1206 moves to above the protrusion 1203, the extension rod 1206 Affected by the upper end of the bent rod 13, it cannot move synchronously with the fixed shaft 1201. At this time, the extension rod 1206 will drive the rotating sleeve 903 to rotate. After rotating a certain angle, the extension rod 1206 passes over the bent rod 13. At this time, under the action of the return spring 1207, the extension rod 1206 slides downward along the chamfer 1204 and slides into the gap between the other protrusions 1203. At this time, the rotating sleeve 903 rotates exactly 90°, and the rotation of the rotating sleeve 903 will drive the rotating plate 509 to rotate synchronously. The rotating shaft 503 and the placement seat 504 are driven to rotate 90° through the universal joint 508 and the telescopic sleeve 507, thereby driving the refrigerator glass partition to rotate 90°. In addition, when the rotating sleeve 903 rotates, the first lifting ring 904 will also rotate synchronously.When the first lifting ring 904 rotates, the triangular block 907 and the extrusion block 512 are against each other, pushing the first lifting ring 904 downward and compressing the thrust spring 906. When the triangular block 907 passes over the extrusion block 512, the thrust spring 906 drives the first lifting ring 904 to move upward. Under the action of the damping slider, the first lifting ring 904 moves slowly. At this time, the lifting rod 510 cannot be supported by the first lifting ring 904 and is separated from the anti-slip pad 511. During the slow rise of the first lifting ring 904, the transverse plate 502 is The refrigerator glass partition can slide on the sliding seat 501, so that the refrigerator glass partition can be rotated 90 degrees and then adjusted again by the correction mechanism 7. Then, it passes through another correction mechanism 7 and another polishing mechanism 8, so that the four edges of the refrigerator glass partition can be fully polished. Finally, as the conveyor belt 3 moves, the refrigerator glass partition moves out of the pressing mechanism 6. The operator can remove the polished refrigerator glass partition from the other end of the conveyor belt 3, realizing continuous polishing of the refrigerator glass partition, improving the degree of automation and polishing efficiency.
