Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of extruded polystyrene board linear motor cross cutting device. BACKGROUND

[0002] Extruded polystyrene board is the abbreviation of extruded polystyrene foam board, which is also commonly known as extruded board. It is a hard foam plastic board made of polystyrene resin and a polymer that is injected with a catalyst while being heated and mixed. The board has a closed-cell structure with independent air bubbles. It is an environmentally friendly insulation material with excellent properties such as high compression resistance, low water absorption, moisture resistance, air tightness, light weight, corrosion resistance, super aging resistance, and low thermal conductivity. It is used in low-temperature storage grounds, parking platforms, airport runways, and highways. It is a new material that is cost-effective, high-quality, and can provide thermal insulation and moisture resistance. It has a promising future. In the production process of extruded polystyrene board, different sizes are often required. To meet customer needs, some extruded polystyrene boards need to be cut. The cross cutting device is one of the cutting methods.

[0003] However, the traditional extruded polystyrene board cross cutting device is usually driven by a motor to move the ball screw, which in turn drives the cutter to move horizontally to cut the extruded polystyrene board. This design can only be used for production lines with a speed of less than 45 m / min. When the production line speed is faster, the ball screw transmission structure will produce a lot of noise and the device will overheat, affecting its use. Moreover, the extruded polystyrene board does not have a pressing structure during cross cutting, and the cutter can easily shift during cross cutting, resulting in poor stability and affecting the cross cutting quality.

[0004] Therefore, it is necessary to invent a kind of extruded polystyrene board linear motor cross cutting device to solve the above problems. INVENTION CONTENTS

Furthermore, the pressing mechanism can press the extruded polystyrene board on the transmission belt, preventing it from shifting during cross cutting. This ensures the cross cutting quality of the extruded polystyrene board.

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0033] This utility model provides, for example Figures 1-7 The extruded polystyrene board linear motor cross-cutting device shown includes a base frame 1, a frame-shaped knife holder 2 disposed above the base frame 1, and a conveyor belt 3 installed on the top of the base frame 1 for supporting the extruded polystyrene board;

[0034] The base frame 1 is provided with a drive assembly 4 on the top. The drive assembly 4 includes a guide rail 41 installed on the top of the front and rear sides of the base frame 1, a movable plate 42 installed on the top of the guide rail 41, and a linear motor 43 provided at the bottom of the movable plate 42 for driving the movable plate 42 to move along the length direction of the guide rail 41.

[0035] The cutter 5 is installed inside the cutter holder 2, and a moving component 6 is provided on the top of the cutter holder 2 for driving the cutter 5 to move horizontally along the length of the cutter holder 2, so that the cutter 5 cuts the extruded polystyrene board on the top of the conveyor belt 3.

[0036] The bottom edge of the knife holder 2 is connected to the top of the support plate 8, and the top edge of the knife holder 2 is also provided with a pressing mechanism 9 for pressing the extruded polystyrene board above the support plate 8.

[0037] The pressing mechanism 9 includes a mounting bracket 91 installed on the top edge of the knife holder 2. Screws 92 are provided on both the front and rear side walls of the mounting bracket 91. A push plate 93 is threaded to the outer side of the screws 92. A cylinder 94 is installed at the bottom of the push plate 93. A connecting plate 95 is installed at the output end of the cylinder 94. A pressure plate 96 is installed at the bottom of the connecting plate 95.

[0038] In one embodiment, base plates 7 are installed on the bottom of both the front and rear sides of the tool holder 2. The two base plates 7 are respectively connected to the top of the two moving plates 42, so that when the linear motor 43 drives the moving plates 42 to move along the guide rail 41, it can drive the entire tool holder 2 to move accordingly, thereby synchronizing the transmission speed of the extruded polystyrene board on the conveyor belt 3.

[0039] In one embodiment, at least one limiting post 10 is provided between the top and bottom of each side wall of the mounting bracket 91, so that the push plate 93 can smoothly move upward or downward when the screw 92 rotates. The limiting post 10 is provided through the push plate 93, and a sliding sleeve 11 is installed at the connection between the push plate 93 and the first limiting post 10 to improve the connection tightness between the push plate 93 and the screw 92, ensuring that the push plate 93 can be driven by the screw 92 to move up and down. Furthermore, at least one extension is provided at the bottom of each of the two push plates 93. The retractable rod 12 ensures high stability when the pressure plate 96 moves downward, allowing the cylinder 94 to work more stably. The top of the mounting bracket 91 is also equipped with a drive motor 13. The output end of the drive motor 13 is connected to the top of the two screws 92 via a belt, enabling the two screws 92 to rotate synchronously in the forward or reverse direction. The adjacent sides of the two pressure plates 96 are bent upward to form folded edges 14. There is a transverse cutting gap between the two folded edges 14 for the cutter 5 to pass through, thereby achieving transverse cutting of the extruded polystyrene board.

[0040] The specific implementation method is as follows: When this utility model is used, the moving component 6 is driven horizontally by a screw drive, belt drive, or cylinder 94. It will not be described in detail here. That is, the moving component 6 is not specifically described. For those skilled in the art, it is fully understandable that the moving component 6 realizes the specific implementation of the cutting blade 5 moving along the blade holder 2 to complete the cross-cutting of the extruded polystyrene board. Therefore, for the sake of space and to avoid redundancy, the specific detailed description of the moving component 6 is omitted and only mentioned in the way of functional limitation.

[0041] Meanwhile, in this utility model, the upper support belt of the conveyor belt 3 passes through the cutter holder 2 and is located above the bearing plate 8 on the bottom edge of the cutter holder 2. This allows the bearing plate 8 to provide support for the extruded polystyrene board at the top of the upper support belt when the extruded polystyrene board is conveyed to the bottom of the cutter holder 2 on the conveyor belt 3. This support plate 8 is used to cooperate with the pressure plate 96 to complete the pressing operation of the extruded polystyrene board. The conveyor belt 3 does not provide the power for the extruded polystyrene board to move; it is only used to lift the extruded polystyrene board. The power for the extruded polystyrene board to move is provided by an external traction device. Since the extruded polystyrene board is always in motion, the cutter holder 2 needs to be able to follow the conveying speed of the extruded polystyrene board at the top of the conveyor belt 3 so that the extruded polystyrene board and the cutter 5 are relatively stationary and the cut is a straight line.

[0042] Specifically, when the extruded polystyrene board is produced on the production line, the extruded polystyrene board that needs to be cut crosswise will move along the length of the conveyor belt 3 at the top until it moves directly below the cutter holder 2. At the same time, the drive component 4 will work synchronously, that is, the linear motor 43 automatically tracks the conveying speed of the extruded polystyrene board at the top of the conveyor belt 3, drives the moving plate 42 to move along the guide rail 41 in the same direction as the transmission of the extruded polystyrene board, and the transmission speed of the extruded polystyrene board is equal to that of the extruded polystyrene board. Furthermore, the base plate 7 drives the entire cutter holder 2 to move, so that the extruded polystyrene board remains relatively stationary with respect to the cutter holder 2 during the transmission process, and is always directly below the cutter holder 2.

[0043] At this time, the pressing mechanism 9 works, that is, the output end of the drive motor 13 rotates in the forward direction, and the two screws 92 rotate in the same direction through the belt, which in turn causes the sliding sleeve 11 to drive the push plate 93 to move downward along the screw 92. This further causes the cylinders 94 on both sides, the connecting plate 95, and the pressure plate 96 to move downward synchronously. When the pressure plate 96 is adjacent to the extruded polystyrene board above the bearing plate 8, the output end of the drive motor 13 stops rotating and the output end of the cylinder 94 extends downward, which causes the connecting plate 95 to drive the pressure plate 96 to move downward and then contact the top of the extruded polystyrene board. Together with the bearing plate 8, they apply pressure to the extruded polystyrene board, so that the extruded polystyrene board can be pressed on the top of the conveyor belt 3 while moving on the conveyor belt 3 under the traction of the external traction equipment.

[0044] Subsequently, the moving component 6 drives the cutter 5 to move along the length of the cutter holder 2, so that the cutter 5 passes through the transverse cutting gap between the two folded edges 14, thus completing the transverse cutting operation of the extruded polystyrene board. Then, the output end of the cylinder 94 retracts upward, and through the connecting plate 95, it drives the pressure plate 96 away from the extruded polystyrene board. The drive motor 13 rotates in the opposite direction, driving the push plate 93 and the pressure plate 96 to reset upward. The cutter 5 is also reset under the drive of the moving component 6. At this time, the cutter holder 2 will return to the initial position under the action of the linear motor 43, waiting for the next extruded polystyrene board on the conveyor belt 3 to be transported to the bottom of the cutter holder 2. The above operation is repeated until the transverse cutting production process of the extruded polystyrene board is completed.

[0045] The downward movement of the pressure plate 96 is divided into two sections. In the second section, the drive motor 13 is replaced by the cylinder 94. This design allows the extruded polystyrene board linear motor 43 cross-cutting device to first coarsely adjust the distance between the pressure plate 96 and the extruded polystyrene board by the drive motor 13, and then finely adjust the distance by pushing the pressure plate 96 against the extruded polystyrene board by the cylinder 94. This allows for more precise pressing of the extruded polystyrene board.

[0046] In summary, during the entire cross-cutting process, the movement of the blade holder 2 is driven by the linear motor 43. Compared with the traditional screw drive, the linear motor 43 drives the blade holder 2 to move faster, which is suitable for high-speed production lines. Moreover, the linear motor 43 has low noise and does not generate much heat during use, resulting in a longer service life for the cross-cutting device. At the same time, the pressing mechanism 9 can press the extruded polystyrene board on the conveyor belt 3, so that the extruded polystyrene board will not deviate when the cutter 5 cross-cuts the extruded polystyrene board, which has high stability and ensures the cross-cutting quality of the extruded polystyrene board, resulting in high production quality of the extruded polystyrene board.

[0047] This embodiment specifically solves the problems of existing traditional extruded polystyrene board cross-cutting devices, which are only suitable for production lines with a speed of less than 45m / min. When the production line speed is higher, the ball screw drive structure will generate a lot of noise and the device will overheat, affecting its use. In addition, there is no clamping structure when the extruded polystyrene board is cross-cut, and the cutter 5 is easy to deviate during cross-cutting, resulting in poor stability and affecting the cross-cutting quality.

[0048] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
