Description

Technical Field

[0001] The utility model relates to the technical field of blanking plates, and particularly relates to a blanking device with adjustable angle and anti-rotation function. Background Art

[0002] The blanking plate is mainly installed on an inclined feeder to facilitate the dropping of materials and avoid the phenomenon of material falling during the blanking process, which is a feeder component.

[0003] A kind of anti-falling blanking plate for inclined feeder disclosed in Chinese Patent CN210709254U includes a blanking plate. A discharge groove is formed on the surface of the blanking plate. Adjusting plates are arranged on both sides at one end inside the discharge groove. One side of the top end of the adjusting plate is rotatably connected with a connecting rod. A fixing block and a connecting block are respectively sleeved outside the connecting rod. Tooth grooves are formed on the surfaces of one ends of the fixing block and the connecting block. The fixing block is fixed on the top surface of the adjusting plate.

[0004] When the above-mentioned existing blanking plate is in use, when pushing the adjusting plate inward, the tooth grooves on the end faces of the fixing block and the connecting block exert forces on each other, so that the connecting block moves upward, and then the adjusting plate rotates to the optimal position. When it is necessary to turn the adjusting plate outward, due to the limitation of the tooth groove, the connecting block needs to be pulled upward to adjust the angle, which is inconvenient for the operator to use.

[0005] To solve the above problems, the utility model provides a blanking device with adjustable angle and anti-rotation function. Summary of the Utility Model

The blanking plate is rotationally installed on the two fixing plates with limited movement; first clamping blocks are rotationally installed with limited movement on the inner walls of the fixing plates. The two ends of the blanking plate are respectively fixedly connected with the two first clamping blocks; square holes are formed on the opposite surfaces of the two fixing plates; square shafts are slidably installed in the square holes. Second clamping blocks are fixedly connected to the opposite ends of the two square shafts. Clamping teeth are arranged on the opposite ends of the second clamping blocks and the first clamping blocks. The first clamping blocks and the second clamping blocks are engaged and connected through the clamping teeth.

[0008] Preferably, a receiving seat is fixedly installed on the side wall of each fixing plate. An installation ring is fixedly connected to the outside of the first clamping block. The installation ring is rotationally installed inside the receiving seat.

[0012] Beneficial Effects

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The angle-adjustable and anti-rotation blanking device is provided with a square shaft, a spring, a fixing plate, a screw and a clamping tooth; when adjusting the angle of the blanking plate, whether it is flipped upward or downward, the blanking plate can be directly turned to adjust, and the blanking plate can maintain its tilt angle under the action of a certain elastic force of the spring. The steps are simple and convenient for the operator to use.

[0015] 2.

[0021] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0022] See alsoFigures 1-3 The utility model provides a technical solution: a blanking device with adjustable angle and anti-rotation, comprising a blanking plate 1 and a fixed plate 6, wherein the blanking plate 1 is mounted on the two fixed plates 6 for limited rotation.

[0023] The fixing plate 6 can be fixed at the discharge port of the equipment, and the shape of the fixing plate 6 is L-shaped.

[0024] The first clamping block 2 is mounted on the inner wall of the fixing plate 6 for limited rotation.

[0025] Specifically, a receiving seat 9 is fixedly mounted on the side wall of the fixing plate 6 , and a mounting ring is fixedly connected to the outer side of the first clamping block 2 , and the mounting ring is rotatably mounted inside the receiving seat 9 .

[0026] Two ends of the blanking plate 1 are fixedly connected to two first clamping blocks 2 respectively.

[0027] Square holes are provided on the opposite surfaces of the two fixing plates 6. Square shafts 4 are slidably installed in the square holes.

[0028] Furthermore, a spring 5 is fixedly connected to the inner wall of the fixing plate 6 , and the other end of the spring 5 is fixedly connected to the second clamping block 3 . The spring 5 is sleeved on the outer side of the square shaft 4 .

[0029] The opposite ends of the two square shafts 4 are fixedly connected with the second clamping block 3 , and the opposite ends of the second clamping block 3 and the first clamping block 2 are provided with clamping teeth 8 , and the first clamping block 2 and the second clamping block 3 are meshed and connected via the clamping teeth 8 .

[0030] Specifically, the latch teeth 8 are evenly distributed around the axis of the first latch block 2 and the second latch block 3 , and the latch teeth 8 are trapezoidal in shape with the narrow end facing outwards.

[0031] In order to prevent the angle of the blanking plate 1 from changing due to continuous impact of the material, a threaded tube is fixedly connected to one end of the second block 3 corresponding to the first block 2, a through hole is opened inside the first block 2, and a countersunk hole is opened at the end of the first block 2 away from the second block 3. The screw 7 passes through the through hole on the first block 2 and is bolted to the threaded tube on the second block 3.

[0032] Working principle:

[0033] When in use, if the angle of the blanking plate 1 needs to be adjusted, Figure 1 In the state shown, the blanking plate 1 can be directly pushed with force. Since the shape of the teeth 8 of the first clamping block 2 and the second clamping block 3 is a trapezoid with an inclined surface, when the first clamping block 2 rotates with the blanking plate 1, the inclined surface of the teeth 8 cooperates with the second clamping block 3 to push the second clamping block 3 away from the first clamping block 2, thereby compressing the spring 5.

[0034] During the adjustment process, the latching teeth 8 of the first clamping block 2 and the second clamping block 3 will be in continuous contact, thereby achieving the purpose of precise adjustment.

[0035] After the blanking plate 1 is adjusted to the proper angle, under the action of the spring 5, the second clamping block 3 will re-clamp the first clamping block 2, and at this time, the angle adjustment of the blanking plate 1 is completed. When adjusting outward and inward, the blanking plate 1 can be directly pulled, and the steps are simple, which is convenient for the operator to use.

[0036] When the weight borne by the blanking plate 1 is not large, the blanking plate 1 can be adjusted by hand. If the blanking plate 1 bears a large weight, after the initial angle adjustment of the blanking plate 1, the screw 7 can be installed, and the screw 7 is bolted to the threaded pipe fixed to the second clamping block 3, so that the head of the screw 7 is completely sunk into the counterbore of the first clamping block 2, and the second clamping block 3 and the first clamping block 2 are bolted together. Furthermore, when the blanking plate 1 bears a large weight, the blanking plate 1 will not flip, preventing the material from continuously impacting and changing the angle of the blanking plate 1, and thus avoiding the change of the blanking speed.

[0037] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
