[Technical field]

[0001] The utility model relates to the technical field of artificial board production, in particular to a material removal mechanism and a wood chip foreign body removal system. [Background technology]

[0002] Wood chips are needed for the manufacture of artificial boards. Wood chips are usually mixed with various foreign objects, such as stones, metals, plastics, bricks and other hard impurities. These foreign objects will greatly affect the subsequent shavings processing.

[0003] In order to prevent foreign matter from affecting the subsequent processing of wood chip raw materials, foreign matter in the wood chip raw materials needs to be removed. The traditional approach is to manually detect foreign matter in the wood chip raw materials and remove foreign matter manually, but this approach is inefficient and difficult to remove foreign matter completely.

[0004] Of course, there are also solutions in the prior art that can automatically remove foreign matter. For example, the Chinese invention patent application with application number CN202211704695.2 discloses a method and device for removing foreign matter from wood shavings based on X-ray identification, which can fully detect, identify and remove debris; however, the device's material removal mechanism uses multiple conveyor belts arranged side by side, and each conveyor belt is driven by a cylinder to lift and lower to remove foreign matter, which has the following defects: 1. There are gaps between adjacent conveyor belts, which are prone to jamming; 2. Each conveyor belt needs to be equipped with a power device, and the overall cost is high; 3. The installation requirements are high, and each conveyor belt needs to be on the same horizontal plane. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on the problem, and this case was born. [Utility Model Content]

[0049] Example 1

[0050] See also Figures 1 to 3As shown, a preferred embodiment of a material-ejecting mechanism 100 of the utility model comprises a supporting structure 1, a plurality of material-ejecting plates 2 and a plurality of telescopic components 3; each of the material-ejecting plates 2 is arranged side by side, and specifically, a gap is left between two adjacent material-ejecting plates 2, so that the two adjacent material-ejecting plates 2 will not affect each other during operation; one end of each of the material-ejecting plates 2 is arranged downward and serves as a free end, and the other end of each of the material-ejecting plates 2 is rotatably connected to the supporting structure 1, and specifically, the material-ejecting plates 2 can be arranged tilted or vertically. The utility model is vertically arranged; each of the telescopic parts 3 is rotatably installed on the supporting structure 1, and the telescopic end of each of the telescopic parts 3 is correspondingly connected to the middle part of the push plate 2, so that the push plate 2 is driven to swing up and down by the telescopic part 3, so as to utilize the telescopic part 3 to drive the push plate 2 to remove foreign matter (such as stone, metal, plastic, brick, etc.); when the utility model is working, when foreign matter is detected in the material, the telescopic part 3 corresponding to the foreign matter can be controlled to drive the push plate 2 to swing upward, so that the push plate 2 removes the foreign matter.

[0051] Compared with the prior art, the material picking mechanism 100 of the present invention has at least the following beneficial effects:

[0052] 1. The design of the ejection mechanism 100 includes a plurality of pusher plates 2 arranged side by side, and each pusher plate 2 is controlled to work independently by a telescopic component 3. When in use, the corresponding telescopic component 3 can be controlled according to the position of the foreign matter to drive the pusher plate 2 to automatically eject the foreign matter, which has good flexibility in use and high ejection efficiency.

[0053] 2. One end of each push plate 2 of the ejecting mechanism 100 is set downward, so that each push plate 2 is in a downward tilted or vertical state. The material will hardly contact the push plate 2 during the downward falling process, and will not enter the gap between two adjacent push plates 2, thereby avoiding material jamming.

[0054] 3. The foreign matter can be removed by only using the telescopic component 3 to drive the push plate 2 to swing, without the need to set up other power devices, which can reduce costs.

[0055] 4. Since each push plate 2 is only used to remove foreign matter and the push plate 2 hardly contacts the material during normal operation, each push plate 2 does not need to be aligned for installation. Therefore, the installation requirements for each push plate 2 are low.

[0056] In a preferred embodiment of the utility model, side baffles 21 are provided on both sides of each push plate 2. By providing the side baffles 21 on both sides of the push plate 2, on the one hand, the wood chip raw materials can be blocked so that the wood chip raw materials will not enter the gap between the two push plates 2, thereby effectively preventing the material from being stuck; on the other hand, it can ensure that the push plate 2 will not slide off the two sides of the push plate 2 during the process of removing foreign objects.

[0057] In a preferred embodiment of the present utility model, the support structure 1 includes a first support plate 11, a second support plate 12, a first support beam 13 and a second support beam 14; the first support beam 13 is located above the second support beam 14, one end of the first support beam 13 and the second support beam 14 are fixedly connected to the first support plate 11, and the other ends of the first support beam 13 and the second support beam 14 are fixedly connected to the second support plate 12, so that the first support plate 11, the second support plate 12, the first support beam 13 and the second support beam 14 form a whole to ensure the support strength; in the specific implementation of the present utility model, the first support plate 11 and the second support plate 12 can be made of stainless steel plates, and the first support beam 13 and the second support beam 14 can be made of stainless steel square tubes. Of course, the present utility model is not limited to this, and support plates and support beams made of other materials can also be used in the specific implementation;

[0058] A plurality of first hinged seats 131 are arranged on the first support beam 13, and the upper end of each of the push plates 2 is hinged to one of the first hinged seats 131, so that the push plate 2 can rotate around the first hinged seat 131 driven by the telescopic component 3, thereby realizing the up and down swinging function of the push plate 2; a plurality of second hinged seats 141 are arranged on the second support beam 14, and one end of each of the telescopic components 3 is hinged to one of the second hinged seats 141, so that the telescopic component 3 can rotate around the second hinged seat 141.

[0059] In a preferred embodiment of the utility model, a material guide door plate 4 is provided between the first support plate 11 and the second support plate 12 at the upper position corresponding to each of the push plates 2. When the material removal mechanism 100 of the utility model is used, it is necessary to connect the material guide door plate 4 with the belt conveyor for conveying materials, so that the materials output by the belt conveyor can enter the material guide door plate 4, and the materials fall down under the guidance of the material guide door plate 4; at the same time, the material guide door plate 4 can also prevent dust, waste chips, etc. from entering the hinged position at the upper end of the push plate 2 to avoid affecting the normal rotation of the push plate 2.

[0060] In a preferred embodiment of the present invention, a dust shielding plate 5 is provided above the material guiding door plate 4 to achieve the effect of shielding dust and preventing dust.

[0061] As a specific implementation of the present invention, the telescopic component 3 is a cylinder. Of course, the present invention is not limited to this, and other telescopic components, such as an electric push rod, etc., can also be used in specific implementation.

[0062] In a preferred embodiment of the utility model, a third hinge seat 22 is provided in the middle of the back side of each push plate 2, and the telescopic end of the telescopic component 3 is hinged to the third hinge seat 22, so that the telescopic component 3 can drive the push plate 2 to swing up and down.

[0063] Example 2

[0064] See also Figures 1 to 8 As shown, a preferred embodiment of a wood chip foreign body removal system 200 of the utility model comprises a feed vibrating screen 6, a belt conveyor 7, a foreign body detection mechanism 8, a foreign body collection hopper 9 and a material removal mechanism 100; wherein, the specific structure of the material removal mechanism 100 is described in detail in the embodiment 1, which will not be described in detail here;

[0065] The belt conveyor 7 is arranged below the output end of the feed vibrating screen 6, the foreign matter detection mechanism 8 is arranged in the middle of the belt conveyor 7, and a conveying channel (not shown) is left between the foreign matter detection mechanism 8 and the belt conveyor 7, so that the wood chip raw materials can pass from under the foreign matter detection mechanism 8; the picking mechanism 100 is arranged below the output end of the belt conveyor 7, and the foreign matter collecting hopper 9 is arranged in front of the picking mechanism 100, so that the foreign matter collecting hopper 9 can receive the foreign matter removed by the picking mechanism 100 to collect the foreign matter, and a falling space 10 is formed between the foreign matter collecting hopper 9 and the picking mechanism 100, so that the wood chip raw materials can fall down through the falling space 10. When the utility model is implemented specifically, it also includes a control device (not shown in the figure). The feed vibrating screen 6, the belt conveyor 7, the foreign matter detection mechanism 8 and the material removal mechanism 100 are all electrically connected to the control device so that the control device can be used to control the operation of the feed vibrating screen 6, the belt conveyor 7, the foreign matter detection mechanism 8 and the material removal mechanism 100.

[0066] When the wood chip foreign body removal system 200 of the utility model is working, the wood chip raw materials (specifically, it can be large wood chip raw materials) are put into the feed vibrating screen 6, the wood chip raw materials are shaken out by the feed vibrating screen 6, and the shaken out wood chip raw materials are transported to the belt conveyor 7; the belt conveyor 7 transports the wood chip raw materials to the bottom of the foreign body detection mechanism 8, and the foreign body detection mechanism 8 performs foreign body detection on the wood chip raw materials. When foreign bodies are detected in the wood chip raw materials, the specific position of the foreign bodies is located, and the telescopic component 3 corresponding to the position is controlled to prepare for work, and when the belt conveyor 7 outputs the wood chip raw materials, the telescopic component 3 drives the push plate 2 to swing upward to remove the foreign bodies into the foreign body collection hopper 9, and the wood chip raw materials fall down through the falling space 10.

[0067] In a preferred embodiment of the present utility model, the foreign body detection mechanism 8 includes a mounting cabinet 81, an X-ray generator 82, an X-ray reflector 83 and an X-ray channel 84;

[0068] The installation cabinet 81 is arranged above the belt conveyor 7; the X-ray channel 84 is arranged in the installation cabinet 81 along the vertical direction, the X-ray generator 82 is arranged at the inner top of the installation cabinet 81, the X-ray reflector 83 is arranged in the belt conveyor 7, and the X-ray generator 82 and the X-ray reflector 83 are both arranged to align with the X-ray channel 84. When working, the X-ray is emitted by the X-ray generator 82, and the X-ray passes through the X-ray channel 84 to irradiate the wood chip raw material, and then the X-ray is reflected to the X-ray generator 82 by the X-ray reflector 83. Since the material density of the normal wood chip raw material is greatly different from the material density of the foreign matter, the reflected X-ray can be used to judge whether the wood chip raw material has foreign matter. It should be noted that the specific implementation principle and structure of detecting foreign matter by X-ray are well known to those skilled in the art. The utility model only applies the existing X-ray detection mechanism to the detection of wood chip raw materials, so the foreign matter detection mechanism 8 will not be introduced in detail here.
