Description

Technical Field

[0001] The utility model relates to the technical field of automatic feeding, in particular to a gravity-type automatic blanking device. Background Art

[0002] The working principle of the gravity-fed automatic feeding device is based on the natural descent of materials under the action of gravity. When materials are placed in the storage chamber of the device, due to the action of gravity, the materials will naturally slide along the designed path inside the device, thus achieving feeding.

[0003] The gravity-type automatic blanking device in the prior art lacks a limiting structure for freely rolling materials. First, since the material is prone to rolling under the action of gravity, there is no limiting structure to constrain its movement trajectory, which causes the material to easily tilt and get stuck during the blanking process. This not only affects the accuracy and stability of the blanking, but may also cause the interruption of the production line, requiring manual intervention and adjustment, thereby increasing production costs and reducing production efficiency. Secondly, the tilting and jamming of the material may also cause material accumulation and blockage, further exacerbating the failure rate of the production line. The accumulated material may occupy the limited space of the equipment, making it impossible for subsequent materials to be dropped normally, and may even damage the equipment. The blocked material may cause the equipment to overload or shut down, requiring time and resources to clean and repair. Utility Model Content

DETAILED DESCRIPTION

[0042] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] like Figure 1-3As shown, a gravity-type automatic blanking device includes a feeding device 1; a feeding rack 2, fixed on the feeding device 1, and the feeding rack 2 is arranged at an angle; a fixed plate 3, fixed on the feeding device 1, and the fixed plate 3 is located above the feeding rack 2; a limit plate 4, which is movably arranged on the fixed plate 3, and the limit plate 4 is located between the feeding rack 2 and the fixed plate 3; a top frame 6, fixed to the top surface of the fixed plate 3;

[0044] The two cams 73 are fixed on the two slides 71, and the two slides 73 are slidably arranged in the two slides 72; a tension spring 74 is provided between the two slides 73; two limit plates 75 are fixed on the ends of the two slides 71 away from each other, and the material is placed on the feeding rack 2 and slides along the feeding rack 2 under the action of gravity to realize automatic feeding. During the material feeding process, the staff can adjust the limit plate 1 4 and the two limit plates 75 according to the size of the material until the limit plate 1 4 and the two limit plates 75 are in contact with the material, and the limit plate 1 4 and the two limit plates 75 are used to provide a limit for the material to ensure stability during the material feeding process and avoid material jamming.

[0045] The gravity-type automatic blanking device also includes an adjustment structure, which is arranged on the top frame 6. The adjustment structure includes: a side plate 81 fixed to the side of the top frame 6; two horizontal plates 82, respectively fixed to the two sliders 73; a rotating shaft 83, rotatably mounted on the top surface of the side plate 81; a control plate 84, fixedly sleeved on the rotating shaft 83, and placed between the two horizontal plates 82. The cross-section of the control plate 84 is an elliptical structure.

[0046] The gravity-type automatic blanking device also includes a positioning structure, which is arranged on the top frame 6. The positioning structure includes: a mounting bracket 91, which is fixed to the top surface of the side plate 81; a positioning ring 92, which is slidably sleeved on the rotating shaft 83, and the positioning ring 92 is located above the mounting bracket 91. The inner ring of the positioning ring 92 and the outer surface of the rotating shaft 83 fit each other; a spring 93, one end of which is connected to the mounting bracket 91 and the other end is connected to the positioning ring 92; a screw cap 94, which is fixed to the top of the rotating shaft 83; a number of latch teeth 95 are respectively provided on the positioning ring 92 and the screw cap 94. When the positioning ring 92 moves downward, the several latch teeth 95 on it are separated from the several latch teeth 95 on the screw cap 94. Without the restriction of the several latch teeth 95, the screw cap 94 can drive the rotating shaft 83 to rotate. Further, the staff rotates the screw cap 94 to make the rotating shaft When the lever 83 rotates, the control plate 84 on the rotating shaft 83 will also rotate accordingly. In the initial state, the two ends of the control plate 84 that are away from each other respectively press against the two sliders 73. At this time, the distance between the two sliders 73 is the largest. When the control plate 84 rotates, the ends of the control plate 84 that are away from each other respectively move away from the two sliders 73. At this time, the two sliders 73 will move closer to each other under the elastic force of the tension spring 74, which makes the two slide plates 71 move closer to each other, and the two limit plates 75 will also move closer to each other. After adjusting the positions of the two limit plates 75, the staff loosens the positioning ring 92, so that the positioning ring 92 will move up under the elastic force of the spring 93 until the several teeth 95 on the positioning ring 92 are engaged with the several teeth 95 on the screw cap 94. At this time, the positioning ring 92 plays a positioning role on the screw cap 94.

[0047] The working principle of this utility model:

[0048] When the gravity-type automatic dropping device proposed by the present invention is in use, the material is placed on the feeding rack 2 and slides along the feeding rack 2 under the action of gravity to realize automatic dropping. During the feeding process, the staff can adjust the limiting plate 1 4 and the two limiting plates 2 75 according to the size of the material until the limiting plate 1 4 and the two limiting plates 2 75 fit the material. The limiting plate 1 4 and the two limiting plates 2 75 are used to limit the material to ensure the stability of the material feeding process and avoid the phenomenon of material jamming.

[0049] As for the limit plate 1 4, it is arranged to be lifted and lowered on the fixed plate 3. The limit plate 1 4 is connected to the fixed plate 3 through a lifting structure. The staff can adjust the position of the limit plate 1 4 through the lifting structure. The lifting structure can adopt a cylinder, a screw rod or other structures with vertical adjustment function. The adjustment principle of the lifting structure is proposed as a prior art and will not be described in detail here. For the two limit plates 2 75, the staff can adjust them through the adjustment structure and the positioning structure. Specifically, the staff first pulls down the positioning ring 92. When the positioning ring 92 moves down, the several teeth 95 on it are separated from the several teeth 95 on the screw cap 94. Without the restriction of the several teeth 95, the screw cap 94 can drive the rotating shaft 83 to rotate. Further, the staff rotates the screw cap 94 to rotate the rotating shaft 83, and the control plate 84 on the rotating shaft 83 will also rotate accordingly. In the initial state, the control plate When the lever 84 is in the unlocked position, the two stoppers 73 are in the unlocked position, and the two stoppers 73 are in the unlocked position, so that the two stoppers 73 can be unlocked.

However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
