Description

Technical Field

[0002] During the production and processing of glass products such as tempered films for mobile phones and glass cover plates, the raw materials of glass sheets are subjected to a series of operations such as cutting, grinding, and laminating to form the final product. Since the raw materials are glass sheets, the stacked materials need to be divided and loaded.

[0003] The existing glass sheet material sorting and feeding device is to set up a material frame, stack the glass sheets and stand them up in the material frame, and set a push plate pushed by a spring in the material frame to push the stacked glass sheets forward from the rear side so that the sheets are always close to the front side of the material frame for the feeding device to absorb and feed. However, the stability of the spring is poor, and the elastic force varies at different lengths, which may easily lead to excessive elastic force, resulting in the sheets being squeezed too tightly and unable to be taken out, or insufficient elastic force, resulting in the sheets on the front side being unable to stick to the material frame to remain upright and tilting, affecting normal feeding. Some feeding components also use electric push rods to push the push plate, but when using multiple material frames to feed at the same time, it is necessary to use multiple sets of electric push rods to push them separately, which is costly and has a high failure rate. There are some shortcomings in use. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a stacking feeding device, comprising a frame 1, on which a plurality of material frame assemblies 2 are arranged in parallel and at intervals along the left and right directions, each material frame assembly 2 comprises a front end plate 21, a rear end plate 22, a sliding plate 24 and a pushing plate 25 which are parallel to each other, and connecting plates 23 are fixedly connected between the two sides of the front end plate 21 and the rear end plate 22, respectively, and the connecting plate 23 is fixedly connected to the frame 1, and the front end plate 21, the rear end plate 22 and the connecting plate 23 form a frame structure, the sliding plate 24 is arranged at the bottom of the frame structure and is slidably connected to the frame 1, and a pushing plate 25 which can move forward and backward is arranged inside the frame structure, and a sheet 11 is placed on the sliding plate 24, and the pushing plate 25 pushes the sliding plate 24 to move forward to clamp the sheet 11 between the pushing plate 25 and the front end plate 21.

[0022] Each group of material frame components 2 is an independent unit, and multiple material frame components 2 are arranged and work simultaneously. Stacked and upright sheets 11 are placed in each material frame component 2 for feeding.

[0023] The connecting plates 23 on both sides are fixed to the frame 1 by bolts. Waist-shaped holes are provided on the connecting plates 23, and the front and rear positions of the frame structure can be slightly adjusted as needed to make it in a suitable position in the front and rear directions and work in conjunction with the material taking device (not shown in the figure).

[0024] The front end plate 21 is a U-shaped structure, with an empty slot opened downward in the middle of the top. When loading, the suction cup of the material taking device moves to the empty slot, sucks the frontmost sheet 11 and then moves upward to take the material.

[0025] Grooves are provided at the bottom of the front end plate 21 and the rear end plate 22, and the sliding plate 24 is embedded under the front end plate 21 and the rear end plate 22 through the grooves, so that the bottom of the sliding plate 24 and the bottom of the frame structure are both installed on the frame 1, and the sliding plate 24 can move forward and backward relative to the front end plate 21 and the rear end plate 22 without being hindered.

[0026] The frame 1 is provided with a guide rail 15 for the sliding plate 24 to slide. The bottom of the push plate 25 is fixedly connected to the sliding plate 24. The connection between the two can be achieved by snapping or bolts, so that when the push plate 25 moves forward and backward, it can drive the sliding plate 24 to move forward and backward, thereby driving the sheet supported on the sliding plate 24 to move.

[0027] The rear side of the front end plate 21 is provided with a plurality of raised limit blocks 28 made of rubber material to position the frontmost sheet 11 to prevent the frontmost sheet 11 from being squeezed tightly against the front end plate 21 and causing excessive friction and being unable to be removed.

[0028] A plurality of tie rods 27 are arranged between the two sides of the front end plate 21 and the rear end plate 22. The two ends of the tie rods 27 respectively extend through the front side of the front end plate 21 and the rear side of the rear end plate 22 and are provided with external threads. Nuts 29 are arranged at the two ends of the tie rods 27. Tightening the nuts 29 presses the front end plate 21 and the rear end plate 22 inward to prevent the sheet 11 from changing its position or tilting in the front-to-back direction or affecting the loading process due to the tilting or deformation caused by squeezing.

[0029] At the same time, multiple pull rods 27 can block and limit the stacked sheets 11 from both sides to keep the sheets 11 in a vertical state, so that when taking and loading materials, the sheets 11 can be placed in the correct posture until the specified processing.

[0030] A push rod 26 extending backward is fixedly connected to the rear side of the push plate 25, and a movable rod 7 is fixedly connected to the rear end of the push rod 26. A driving component for driving the movable rod 7 to move forward and backward is arranged on the frame 1.

[0031] The push rod 26 extends backward through the rear end plate 22 and can move through the rear end plate 22 . A connecting seat for connecting the push rod 26 is provided on the rear side surface of the push plate 25 .

[0032] In this embodiment, the push rods 26 of multiple groups of material frame assemblies 2 extend backward and are commonly connected to a movable rod 7. When the movable rod 7 is pushed to move, the multiple push rods 26 synchronously push the sheets 11 in each material frame assembly 2 forward and squeeze them to the front side.

[0033] The movable rod 7 is supported by the sliding plate 24, the push plate 25 and the push rod 26 to keep it horizontal, and moves forward and backward when subjected to force.

[0034] Furthermore, the driving assembly includes a motor 4, a reducer 5, a rotating shaft 6 and a gear 12. The motor 4 and the reducer 5 are respectively arranged on the frame 1. The input shaft of the reducer 5 is fixedly connected to the output shaft of the motor 4. The rotating shaft 6 is fixedly connected to the output shaft of the reducer 5 and is arranged along the left and right directions. A plurality of bearing seats 13 supporting the rotation of the rotating shaft 6 are fixedly installed on the frame 1. A plurality of gears 12 are arranged at intervals on the rotating shaft 6. A mounting plate 8 in the front and rear directions is fixedly connected to the movable rod 7. A rack 9 meshing with the gear 12 is arranged at the bottom of the mounting plate 8.

[0035] In this embodiment, a fixing plate 3 is provided on the frame 1 , the motor 4 and the reducer 5 are fixedly mounted on the fixing plate 3 , respectively, and the output shaft of the reducer 5 is connected to the rotating shaft 6 via a coupling 14 .

[0036] A plurality of mounting plates 8 are fixedly connected to the bottom of the movable rod 7 . A rack 9 is disposed at the bottom of each mounting plate 8 . Each rack 9 is meshed with a gear 12 .

[0037] The motor 4 can rotate forward and reverse. When the motor 4 rotates, the speed of the reducer 5 is reduced to drive the rotating shaft 6 to rotate, thereby driving the gear 12 to rotate. When the gear 12 rotates, the rack 9 is driven to move, thereby driving the mounting plate 8 and the movable rod 7 to move forward and backward, thereby driving multiple push rods 26 to move synchronously, pushing the material or moving backward to load the material to the front side of the push plate 25. When the first sheet 11 on the front side is taken away, the motor 4 rotates for a certain time, driving the gear 12 to rotate a certain angle, thereby driving the movable rod 7 to move forward a certain distance in a small amplitude, thereby pushing the subsequent sheets 11 forward, so that the front sheet 11 moves forward to the frontmost loading position.

[0038] like Figure 1 and 5 As shown, a material dividing assembly 10 is provided at the front end of the top of the frame 1, and the material dividing assembly 10 includes a bracket 101, a cross bar 102, a scraper 103 and a water blowing nozzle 104. The bracket 101 is fixedly installed at the front end of the top of the frame 1, the cross bar 102 is provided at the top of the bracket 101 and is distributed in left and right reverse directions, the bottom of the cross bar 102 is located above the front end of each material frame assembly 2, and a scraper 103 for blocking the second sheet at the front end is provided, and the bottom of the cross bar 102 and located above the front side of each material frame assembly 2 are provided with a water blowing nozzle 104 for spraying water on the front end sheet.

[0039] Each water blowing nozzle 104 is located just above the frontmost part of a group of sheets 11. When in operation, the water blowing nozzle 104 is connected to the water supply pipe to spray water to the two frontmost sheets 11 in the group of sheets 11, and the two frontmost sheets 11 are separated by the impact force and water flow to avoid mutual adhesion.

[0040] In this embodiment, when the two frontmost sheets 11 are tightly fitted, since the surface of the sheets 11 is smooth and flat, and the friction force and the mutual attraction between the two are large, the frontmost sheet 11 will drive the second sheet 11 to move upward when it is taken out. At this time, the scraper 103 is just on the back side of the first sheet 11 and above the second sheet 11. When the second sheet 11 rises, it will be blocked by the scraper 103 and separated from the first sheet 11, and fall back under the action of gravity, and then be moved forward by the push plate 25 to the front side to be in the loading position.

[0041] The bracket 101 is fixed to the frame 1 by bolts. A waist-shaped hole is opened on the bracket 101 to adjust the front and rear positions of the bracket 101, and then adjust the front and rear positions of the scraper 103 and the water blowing nozzle 104. The front and rear positions of the material dividing assembly 10 are adjusted according to the thickness of the sheets 11 of different specifications to make it in a suitable working position.

[0042] Furthermore, a height adjustment block 105 is provided on the bracket 101 . The height of the height adjustment block 105 installed on the bracket 101 is adjustable, and the cross bar 102 is fixedly connected to the top of the height adjustment block 105 .

[0043] In this embodiment, the height adjustment block 105 is installed on the bracket 101 by bolts. A plurality of height adjustment blocks 105 are spaced apart in the vertical direction on the bracket 101. The installation position of the height adjustment block 105 can be changed, thereby changing the height of the cross bar 102 to adapt to the height of sheets 11 of different specifications.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
