Technical Field
[0001] The utility model relates to the technical field of wood-based panel production equipment, in particular to a screen stretching machine for a paving machine. Background Art
[0002] A paving machine is an important piece of equipment in wood-based panel production. It is a machine that scatters fibers, shavings or wood chips mixed with glue in a loose, uniform and regular manner onto a paving conveyor belt (or backing plate) to prepare for the next hot pressing process. According to the forming principle of the paving head, paving machines can be divided into mechanical paving machines, vacuum air paving machines and mechanical vacuum paving machines.
[0003] When a paving machine is used in certain application scenarios and process requirements, a screen needs to be installed for screening and grading raw materials. After the screen is used for a period of time, its shape changes, affecting the screening effect, and it needs to be replaced. Since the screen is installed on the screen frame, and the newly installed screen needs to be tightened before being installed on the screen frame, traditional manual operation has low efficiency and uneven tightening force around the screen.

Inside the frame, there is a support plate for supporting the screen frame. A screen fixing and tightening mechanism is arranged outside the frame. The screen fixing and tightening mechanism includes screws, a base plate and a pressing plate. A plurality of screws are provided, and the plurality of screws are arranged along the extension direction of the outer side wall of the frame. The screws penetrate through the base plate, and adjusting nuts are arranged on the inner side and the outer side of the base plate. The pressing plate is detachably connected to the top surface of the base plate.
[0006] As a preference of this technical solution, the frame is a square frame. The four side edges of the square frame are angle steels, and one side edge of the angle steel is the support plate.
[0007] As a preference of this technical solution, legs are arranged at the lower ends of the four corners of the frame, and walking wheels with braking mechanisms are arranged at the lower ends of the legs.
[0008] As a preference of this technical solution, the screen fixing and tightening mechanism is arranged outside the outer sides of three side edges of the square frame.
[0009] As a preference of this technical solution, the base plate is a square pipe, the pressing plate is an angle steel, and the pressing plate and the base plate are connected by bolts.
[0010] As a preference of this technical solution, a reinforcing frame is arranged between the frame and the walking wheels. The reinforcing frame is composed of cross plates connected to adjacent legs.
[0011] Compared with the prior art, in the utility model, a screen frame is placed inside the frame, a screen mesh is placed on the screen frame, and the screen mesh is fixed and tightened by a screen mesh fixing and tensioning mechanism outside the frame. After completion, the screen mesh can be fixed to the screen frame, and the tension is adjusted by an adjusting nut, and the tension can reach a better uniformity, and the adjustment is relatively convenient.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] Please refer to Figures 1-4 , a screen mesh stretching machine of a paving machine of the present utility model includes a frame 1. A support plate for supporting a screen frame is provided inside the frame 1. A screen mesh fixing and tensioning mechanism is arranged outside the frame 1. The screen mesh fixing and tensioning mechanism includes a screw 2, a base plate 3 and a pressing plate 5. A plurality of screws 2 are provided, and the plurality of screws 2 are arranged along the extending direction of the outer side wall of the frame 1. The screw 2 penetrates through the base plate 3 and adjusting nuts 4 are arranged on the inner side and the outer side of the base plate 3. The pressing plate 5 is detachably connected to the top surface of the base plate 3.
[0019] In the specific implementation of the present utility model, the frame 1 is a square frame, that is, a square or a rectangle. The four side edges of the square frame are angle steels. One side edge of the angle steel is a support plate. That is, the four angle steels are connected to form the frame 1. One side edge of the angle steel is vertically arranged, and the other side edge is horizontally arranged. This side plate is the support plate for supporting the sieve frame. An adjusting plate can be arranged on the horizontally arranged side edge. The adjusting plate is placed on the horizontal side edge and is connected and adjusted through strip-shaped through holes to be applicable to sieve frames of different sizes. The base plate 3 and the pressing plate 5 corresponding to the outer sides of the side edges of the square frame are both parallel to the side edge on this side. Legs 6 are arranged at the lower ends of the four corners of the frame 1, and walking wheels 7 with braking mechanisms are arranged at the lower ends of the legs 6. The sieve fixing and tensioning mechanism is arranged on the outer sides of three side edges of the square frame. That is, two opposite sides of the sieve can be fixed and tensioned through the sieve fixing and tensioning mechanism, and only one of the other two sides needs to be tensioned, which can reduce the mechanism of the equipment and reduce costs.
[0020] In the specific implementation of the present utility model, the base plate 3 is a square tube, the pressing plate 5 is an angle steel, and the pressing plate 5 and the base plate 3 are connected by bolts. The height of the pressing plate 5 is flush with the height of the angle steel of the frame 1. A strengthening frame 8 is arranged between the frame 1 and the walking wheel 7. The strengthening frame 8 is composed of cross plates connected to adjacent legs 6, and the cross plates can also be angle steels.
[0021] When the present utility model is specifically used, a sieve frame is placed inside the frame, the sieve mesh is placed on the sieve frame, and the sieve mesh is fixed and tensioned through the sieve fixing and tensioning mechanism outside the frame. After completion, the sieve mesh can be fixed to the sieve frame, and the tensioning is adjusted through adjusting nuts.
