Description

Technical Field

[0001] The utility model relates to the technical field of wood processing, in particular to an anti-skid paving machine for oriented strand boards. Background Art

[0002] Oriented strand board is one of the new types of particle board. When the particles are laid and formed, the upper and lower surface layers of the oriented strand board arrange the glue-mixed particles longitudinally according to their fiber direction, while the core layer particles are arranged transversely to form a three-layer structural board embryo, which is then hot-pressed into an oriented strand board. There are two methods of directional laying: mechanical orientation and electrostatic orientation. The former is suitable for directional laying of large particles, and the latter is suitable for directional laying of fine particles.

[0003] The paving machine is a machine that scatters the fiber, shavings or wood chips mixed with glue loosely, evenly and regularly on the paving conveyor belt to prepare for the next step of hot pressing. Shavings are the upstream process of the paving machine and the source of raw materials for the paving machine. The existing paving machine also has the function of shavings paving.

[0004] For example, the "long net anti-slip device for a paving machine" with patent publication number CN207362451U includes an overrunning clutch arranged on the driven roller shaft of the paving machine, and a reducer and a motor connected to the overrunning clutch.

[0005] The paving machine orients the surface shavings according to the fiber direction through the effects of mechanical orientation and electrostatic orientation. However, in the prior art, since the raw material of the paving machine is produced by the mutual contact and friction between the wood and the blade, if the wood is not fixed during shaving, the wood will be driven to move in the opposite direction by the resistance of the blade, causing collision when the wood moves relative to the outer shell, and interfering with the directional effect of static electricity on the shaving fibers on the paving seat below, thereby causing confusion in the sorting direction of the shaving limiters during paving, affecting the physical properties of the formed particleboard. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that when wood is shavings, it is driven by the resistance of the blade to move in the opposite direction, causing collision when the wood moves relative to the shell, and interfering with the directional effect of static electricity on the shaving fibers on the paving seat below, thereby causing confusion in the sorting direction of the shavings limit during paving, affecting the physical properties of the formed particle board, and an anti-slip paving machine for oriented particle boards is proposed.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an anti-skid paving machine for oriented strand board, comprising a paving seat, a wood storage box and a tool box, the paving seat is composed of a motor and a transmission belt, the tool box is arranged above the paving seat through a positioning frame, the bottom surfaces of the wood storage box and the tool box are both provided with openings in the horizontal direction, and a tool head is fixedly connected to the opening position of the tool box, the wood storage box is slidably connected to the tool box, the two inner side walls of the wood storage box are both provided with card grooves, an anti-skid plate is arranged inside the wood storage box, the two outer side walls of the anti-skid plate are both fixedly connected with card blocks, the anti-skid plate is slidably connected to the wood storage box through the card blocks, the outer side wall of the anti-skid plate is rotatably connected with a positioning bolt, and the positioning bolt is threadedly connected to the outer side wall of the wood storage box.

[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, the utility model provides an anti-skid paving machine for oriented strand board, comprising a paving seat 1, a wood storage box 2 and a tool box 3, the paving seat 1 is composed of a motor and a transmission belt, the tool box 3 is arranged above the paving seat 1 through a positioning frame, the bottom surfaces of the wood storage box 2 and the tool box 3 are both provided with openings in the horizontal direction, and a tool head 6 is fixedly connected to the opening position of the tool box 3, the wood storage box 2 is slidably connected to the tool box 3, the two inner side walls of the wood storage box 2 are both provided with a card slot 14, an anti-skid plate 7 is arranged inside the wood storage box 2, the two outer side walls of the anti-skid plate 7 are both fixedly connected with a card block 13, the anti-skid plate 7 is slidably connected to the wood storage box 2 through the card block 13, the outer side wall of the anti-skid plate 7 is rotatably connected with a positioning bolt 8, and the positioning bolt 8 is threadedly connected to the outer side wall of the wood storage box 2.

[0026] The specific settings and functions of this embodiment are described in detail below. The paving seat 1 is driven by a motor to drive a reducer, thereby driving the transmission belt to move in a directional manner. After the interaction between the wood storage box 2 and the tool box 3, the wood shavings produce raw materials that fall onto the transmission belt. Through the electrostatic directional effect on the paving seat 1, the shavings on the transmission belt are paved in a directional manner and finally transported to the gluing machine for gluing. The shavings of the upper and lower layers of the oriented strand board are arranged longitudinally according to their fiber directions, and the shavings of the middle layer are arranged transversely according to their fiber directions, thereby forming a three-layer structural slab, which increases the stress resistance of the particle board in a certain direction.

[0027] When wood is shaving, its surface and the blade contact and rub against each other to produce shavings. If the position of the wood is not fixed, the wood will be driven in the opposite direction by the resistance of the blade when shaving, which not only affects the effective stroke of the blade on the wood surface and reduces the length of the shavings, but may also cause collision when the wood moves relative to the shell and interfere with the directional effect of static electricity on the shaving fibers on the paving seat 1 below. Therefore, it is necessary to prevent the wood from sliding sideways when shaving. When processing the wood, it is placed in a wood storage box 2. The wood storage box 2 is moved back and forth inside the tool box 3 to allow the blade to scrape off the surface of the wood fiber to produce shavings. A telescopic anti-skid plate 7 is provided inside the wood storage box 2, wherein the distance between the anti-skid plate 7 and the inner wall of the wood storage box 2 is controlled by a positioning bolt 8. The rotation angle of the positioning bolt 8 can be adjusted to change the protruding length of the anti-skid plate 7, thereby fixing both ends of the wood stored in the wood storage box 2 to prevent sliding sideways when shaving.

[0028] Embodiment 2

[0029] like Figure 2 and Figure 4 As shown, casters are installed at the four corners of the bottom end of the paving seat 1. A housing 4 is provided on both sides of the tool box 3 and the paving seat 1. A guide rail 9 is fixedly connected to the inner bottom wall of the tool box 3, and a guide groove 15 is provided at the bottom of the wood storage box 2. The wood storage box 2 and the tool box 3 are slidably connected through the guide rail 9. A servo motor 12 is provided on one side of the tool box 3, and a crankshaft rod 10 is fixedly connected to the output end of the servo motor 12. A rotating rod 11 is rotatably connected at the crank position of the crankshaft rod 10, and the rotating rod 11 is rotatably connected to one end of the wood storage box 2. A shavings guide plate 5 is provided below the tool head 6, and the housing 4 guides the shavings onto the transmission belt of the paving seat 1 through the shavings guide plate 5.

[0030] The effect achieved by the entire embodiment is that, in order to realize the automatic generation of shavings on the paving seat 1, a servo motor 12 is arranged at one end of the tool box 3, the servo motor 12 is located at the outer end of the wood storage box 2, the center of the crankshaft rod 10 is a crank turntable, and the crank turntable pulls the wood storage box 2 to move through the rotating rod 11. When the servo motor 12 runs to drive the crankshaft rod 10 to rotate, the effect of the crank converts the rotation into translation, so that the wood storage box 2 and the tool box 3 produce relative movement, and the reciprocating movement effect is used to make the wood and the tool head 6 contact each other, thereby producing shavings.

[0031] The use method and working principle of the device: First, adjust the rotation angle of the positioning bolt 8, change the position of the anti-slip plate 7, and fix the two ends of the wood stored in the wood storage box 2 to prevent side sliding during shaving;

[0032] Then, the servo motor 12 is started to drive the crankshaft 10, so that the wood storage box 2 and the tool box 3 move relative to each other, and the wood and the tool head 6 are brought into contact with each other by the effect of reciprocating movement, thereby producing wood shavings;

[0033] Finally, the wood shavings produce raw materials that fall onto the transmission belt. Through the electrostatic orientation effect on the paving seat 1, the shavings on the transmission belt are paved in a directional manner and finally transported to the gluing machine for gluing. The shavings of the upper and lower layers of the oriented strand board are arranged longitudinally according to their fiber direction, and the shavings of the middle layer are arranged transversely according to their fiber direction, thus forming a three-layer structural slab.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
