[0019] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1 , Figure 2 The polyurethane insulation board cutting and scrap recycling device shown comprises a conveying mechanism 1, a cutting mechanism 2, a pressing mechanism 3, a polyurethane insulation board 4 and a negative pressure recycling mechanism (not shown). The conveying mechanism 1 is a roller conveyor for conveying the formed long strip polyurethane insulation board 4.

[0021] like Figure 1-3 As shown, the cutting mechanism 2 is installed at the lower side of the conveying mechanism 1, and is used to cut the polyurethane insulation board 4 into required sizes. The cutting mechanism 2 includes a base 21, and the base 21 is a long strip of plate. The base 1 is installed below the conveying mechanism 1 perpendicular to the conveying direction of the conveying mechanism 1. A linear module 22 is installed on the upper surface of the base 1, and a cutting seat 23 is installed on the linear module 22, and a cutting machine 24 is installed on the cutting seat 23. The linear module 22 drives the cutting machine 24 to reciprocate along the base 1, and is used to cut the polyurethane insulation board 4.

[0022] The linear module 22 may be a screw linear module or a synchronous wheel linear module. Taking the synchronous wheel linear module as an example, the linear module 22 includes two parallel guide rails, and the cutting seat 23 is slidably mounted on the two guide rails through a slider. Synchronous wheels are respectively mounted on both ends of the guide rails through bearing seats, one of which is connected to a synchronous motor, and a synchronous belt is wound between the two synchronous wheels, and the cutting seat 23 is connected to the synchronous belt on one side. The synchronous motor drives the synchronous wheel to rotate, and pulls the cutting seat 23 to move back and forth along the guide rails through the synchronous belt, thereby realizing the reciprocating movement of the cutting machine 24.

[0023] like Figure 3 As shown, four guide rods 25 are vertically installed at the four corners of the upper end surface of the cutting seat 23, and a lifting platform 26 is slidably installed on the guide rods 25 through linear bearings, and the cutting machine 24 is installed on the lifting platform 26. A lifting cylinder 27 is installed between the upper surface of the cutting seat 23 and the lower surface of the lifting platform 26, and the lifting cylinder 27 drives the lifting platform 26 to move up and down to adjust the cutting depth of the cutting machine 24.

[0024] like Figure 1 , Figure 3 As shown, a dust hood 28 is installed at the cutting wheel of the cutting machine 24. The dust hood 28 is a semicircular shell with an opening at the upper end. An air vent is opened at the lower end of the dust hood 28, and the air vent is connected to the negative pressure recovery mechanism. During cutting, the scraps generated by cutting fall into the dust hood 28 and are collected into the negative pressure recovery mechanism through the air vent. The negative pressure recovery mechanism can be an industrial vacuum cleaner.

[0025] like Figure 1 , Figure 2 , Figure 4As shown, two clamping mechanisms 3 are installed on the upper side of the conveying mechanism 1, and the two clamping mechanisms 3 are respectively located on both sides of the cutting mechanism 2. The clamping mechanism 3 is used to clamp the polyurethane insulation board 4 during cutting to prevent the polyurethane insulation board 4 from deviating during cutting and causing poor cutting. The clamping mechanism 3 includes a fixed plate 31, which is a long strip of plate. The fixed plate 31 is arranged perpendicular to the conveying direction of the conveying mechanism 1. Two guide rods 32 are vertically installed at both ends of the lower side of the fixed plate 31, and a lifting plate 33 is slidably installed between the two guide rods 32 through a linear bearing. A clamping cylinder 34 is installed between the upper surface of the lifting plate 33 and the lower surface of the fixed plate 31, and the clamping cylinder 34 drives the lifting plate 33 to reciprocate along the guide rod 32. A clamping block 35 is fixedly installed on one side of the lifting plate 33, and the clamping blocks 35 of the two clamping mechanisms 3 are installed relative to each other. The pressing block 35 is a long strip structure, and is arranged perpendicular to the conveying direction of the conveying mechanism 1, and the length of the pressing block 35 is greater than the width of the polyurethane insulation board 4. The lower end surface of the pressing block 35 is lower than the lower end surface of the lifting plate 33, and a foam cushion is attached to the lower end surface of the pressing block 35. The pressing block 35 is used to press the polyurethane insulation board 4, and the setting of the cushion can avoid causing damage to the polyurethane insulation board 4.

[0026] A cavity is provided inside the pressing block 35, and the cavity is connected to the negative pressure recovery mechanism through a pipe (not shown). An adsorption groove 351 is provided on one side of the pressing block 35 close to the cutting mechanism 2, and the adsorption groove 351 extends along the bottom edge of the pressing block 35, and the adsorption groove 351 is connected to the cavity. When in use, the negative pressure recovery mechanism forms a negative pressure in the cavity inside the pressing block 35, so that the scraps generated by cutting are recovered through the adsorption groove 351, thereby improving the recovery efficiency.

[0027] The technical solution provided in the embodiments of the present application has at least the following technical effects or advantages:

[0028] By setting the pressing block into a hollow structure and providing an adsorption groove to communicate with the negative pressure recovery mechanism, the recycling of cutting scraps at the cutting seam is achieved, thereby improving the recycling efficiency and the workshop environment.

[0029] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction.
