Description

Technical Field

[0001] This utility model relates to the field of extruded polystyrene board cutting technology, and in particular to an extruded polystyrene board cutting device. Background Technology

[0002] Extruded polystyrene (XPS) board, also known as extruded polystyrene foam board, is a type of board made from polystyrene resin and other additives through an extrusion process. It features a continuous, uniform surface and a closed-cell honeycomb structure. This material is characterized by high compressive strength, lightweight, non-absorbent, non-breathable yet wear-resistant and degradation-resistant properties. It is also lightweight, easy to use, does not mold, and has excellent corrosion resistance. In addition to serving as thermal insulation, it effectively prevents water and moisture damage, providing protection against leaks, condensation, and freeze / thaw cycles.

[0003] Existing cutting machines can cut XPS boards of different thicknesses. When cutting XPS boards of different thicknesses, the same cutting machine needs to adjust the parameters according to the actual thickness of the XPS board before cutting. When processing XPS boards of different thicknesses, the parameters need to be adjusted repeatedly, which is cumbersome. This results in a limited range of applications for the cutting machine and insufficient processing efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polystyrene board cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An extruded polystyrene (XPS) board cutting device includes a base with a main seat installed inside its top end. A cutting table extending from both ends of the base is fixedly connected to the upper surface of the main seat. A slidable feeding plate is provided on the upper surface of the cutting table. A cutting mechanism for cutting XPS board is fixedly installed on the upper surface of the cutting table.

The device also includes a limiting mechanism located inside one side of the limiting block for blocking and limiting the XPS board on the feeding plate. Finally, the device includes a transmission mechanism installed inside the main seat for transmitting the feeding plate to automatically translate and limiting the feeding plate.

[0007] Preferably, the measuring mechanism includes a measuring rod movably sleeved on the upper surface of the limiting block, and a pad for protecting the measuring rod is provided at the top of the measuring rod. The outer wall of the measuring rod is provided with a scale line layer. An outer roller is fixedly installed at the bottom of the measuring rod. A support spring is fixedly connected between the upper surface of the outer roller shell and the upper surface of the inner wall of the limiting block, and the support spring is wrapped around the outer wall of the measuring rod. A distance sensor is built into the bottom of the distance sensing mechanism.

[0008] Preferably, the limiting mechanism includes a threaded rod disposed on one side of the limiting block. One side of the limiting block has a through-hole inner groove, and a fixing plate is fixedly connected in the inner groove. One end of the threaded rod passes through the fixing plate and is threadedly connected to the fixing plate. A side roller is slidably engaged in the inner groove. One end of the threaded rod passing through the fixing plate is connected to the outer shell of the side roller through a bearing. The outer wall of the end of the threaded rod away from the limiting block has a toothed design.

[0009] Preferably, the upper surface of the cutting table is provided with limiting grooves on both sides, and the lower surface of the feeding plate is fixedly connected with toothed plates on both sides, and the bottom end of the toothed plates is slidably engaged in the limiting grooves corresponding to their positions, and the length of the feeding plate is equal to the length of the toothed plates.

[0010] Preferably, the transmission mechanism includes a connecting rod disposed within a main seat, the main seat having two receiving slots, both ends of the connecting rod being fixedly connected to gears located in the two receiving slots respectively, and the gears being used to mesh with connecting gear plates, a sleeve block being fixedly connected within the main seat, the connecting rod being movably sleeved within the sleeve block, a servo motor being fixedly installed in one of the receiving slots, and the output shaft of the servo motor being fixedly connected to one of the gears.

[0011] Preferably, guide grooves are provided on both sides of the upper surface of the main seat, and the positions of the two guide grooves correspond to the positions of the two toothed plates, and one end of the toothed plate is slidably engaged in the guide groove through the limiting slide groove.

[0012] Preferably, a baffle is fixedly connected to the upper front surface of the feeding plate, and the length of the baffle is greater than the width of the feeding plate. A soft pad layer for contacting the extruded board is adhered to the inner wall of the baffle.

[0013] Preferably, the cutting mechanism includes a cutting frame with a touch panel at the front end, and the cutting frame is mounted directly above the cutting table. The cutting frame has a hydraulic lifting head with a cutter at the bottom, and both sides of the tail end of the hydraulic lifting head are fixedly connected to a fixing plate. The upper surface of the cutting table is fixedly connected to a second support frame located at the tail end of the cutting frame, and both sides of the lower surface of the second support frame are fixedly connected to hollow cavities. The bottom of the fixing plate is fixedly connected to a push rod, the bottom end of which slides through the second support frame and is located in the cavity. The bottom end of the push rod is fixedly connected to a piston block whose outer wall fits against the inner wall of the cavity. An inner support plate is slidably sleeved in the cavity, and the top end of the inner support plate is fixedly connected to a bottom rod. The top end of the bottom rod is fixedly connected to a pressure plate with a diameter larger than the diameter of the cavity. Two limiting springs are fixedly connected between the bottom of the inner support plate and the bottom of the inner wall of the cavity.

[0014] Preferably, a fixing frame located behind the cutting frame is fixedly connected to the upper surface of the cutting table, and a plurality of soft sheets are fixedly connected to the top of the inner wall of the fixing frame, the bottom of the soft sheets overlapping the upper surface of the cutting table.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. By setting limit blocks on both sides below the first support frame, before the extruded board is pushed to the cutting frame by the feeding plate for cutting, the outer rollers and the elastic action of the support spring can squeeze and limit the extruded board to prevent it from sliding or tilting. At the same time, the extruded board can push up the outer rollers from the bottom, so that the measuring rod can move upward to facilitate the observation of the thickness of the extruded board by the scale line layer. The distance sensing mechanism above the measuring rod can monitor the lifting distance of the measuring rod in real time and feed the signal back to the touch panel on the cutting frame. The touch panel can automatically adjust the initial height position and cutting force of the cutter before cutting, so that the cutting machine has a good range of applications and can reduce the time of manual parameter adjustment to improve processing efficiency.

[0017] 2. When the feeding plate is moved by the transmission mechanism, two L-shaped limiting blocks under the first support frame can limit the two sides of the feeding plate, making its movement more stable. Side rollers are set in the inner groove on one side of the inner wall of the limiting block to limit the extruded board on the feeding plate, preventing it from shifting and affecting the cutting accuracy, and also preventing the extruded board from being damaged by bumps. At the same time, the position of the side rollers can be adjusted by the threaded rod to accommodate extruded boards of different widths.

[0018] 3. By setting a toothed plate on the lower surface of the feeding plate, it can cooperate with the limiting slide groove to realize the limiting and guiding function of the feeding plate. The bottom end of the toothed plate passes through the limiting slide groove and meshes with the gear in the main seat. Under the synchronous limiting function of the guide groove on the toothed plate, the feeding plate and the transmission mechanism maintain good structural stability. This cutting machine has the characteristics of compact structure and better stability.

[0019] 4. By setting a fixed connecting plate connected to the hydraulic lifting head, the hydraulic lifting head drives the push rod to descend during the descent process. The descending push rod uses the piston block to compress the air in the cavity and pushes the inner support plate to descend, so as to drive the pressure plate to descend synchronously. Before the cutter cuts the extruded board, it can move synchronously with the cutter and cooperate with the outer roller limit to compress and limit both sides of the other end of the extruded board. This ensures that both ends of the extruded board are automatically pressed to prevent slippage and deviation at either end, which would affect the flatness of the cut. This ensures the cutting effect of the extruded board and at the same time prevents excessive compression of the extruded board and damage to it. Attached Figure Description

[0031] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0032] Reference Figure 1-10 An extruded polystyrene board cutting device includes a base 1 with a main seat 2 installed inside the top end, a cutting table 3 extending from both ends of the base 1 and fixedly connected to the upper surface of the main seat 2, a slidable feeding plate 6 provided on the upper surface of the cutting table 3, a cutting mechanism for cutting extruded polystyrene board fixedly installed on the upper surface of the cutting table 3, and a first support frame 7 located in front of the cutting mechanism and fixedly connected to the upper surface of the cutting table 3. The first support frame 7 is mounted above the feeding plate 6, and two limiting blocks 8 are respectively provided on both sides of the lower surface of the first support frame 7, and the two limiting blocks 8 are respectively located on both sides of the feeding plate 6.

[0033] The measuring mechanism is slidably installed on the upper surface of the inner wall of the limiting block 8 and is used to measure the thickness of the extruded board being fed. The distance sensing mechanism 10 located directly above one of the measuring mechanisms is fixedly installed on the upper surface of the first support frame 7.

[0034] A limiting mechanism is set inside one side of the limiting block 8 to block and limit the extruded board on the feeding plate 6.

[0035] The transmission mechanism, installed inside the main seat 2, is used to drive the feeding plate 6 to move automatically and to limit the feeding plate 6.

[0036] Reference Figure 2 and Figure 3 The measuring mechanism includes a measuring rod 9 movably sleeved on the upper surface of the limiting block 8, and a pad 14 for protecting the measuring rod 9 is provided at the top of the measuring rod 9. The outer wall of the measuring rod 9 is provided with a scale line layer 11. An outer roller 12 is fixedly installed at the bottom of the measuring rod 9. A support spring 13 is fixedly connected between the upper surface of the outer shell of the outer roller 12 and the upper surface of the inner wall of the limiting block 8. The support spring 13 is wrapped around the outer wall of the measuring rod 9. A distance sensor is built into the bottom of the distance sensing mechanism 10. The initial height of the bottom of the outer roller 12 corresponds to the height position of the upper surface of the feeding plate 6. When the feeding plate 6 carries the extruded board into the first support frame 7, the outer roller 12 rolls and moves upward under force when the extruded board comes into contact with the outer roller 12, while the support spring 13 can elastically extend and retract. When the feeding plate 6 exits, the support spring 13 can drive the outer roller 12 to automatically descend and reset, which is convenient for reuse.

[0037] Reference Figure 4 The limiting mechanism includes a threaded rod 15 disposed on one side of the limiting block 8. A through-hole inner groove 17 is opened on one side of the limiting block 8, and a fixing plate 16 is fixedly connected in the inner groove 17. One end of the threaded rod 15 passes through the fixing plate 16 and is threadedly connected to the fixing plate 16. A side roller 18 is slidably engaged in the inner groove 17. One end of the threaded rod 15 passing through the fixing plate 16 is connected to the outer shell of the side roller 18 through a bearing. The outer wall of the end of the threaded rod 15 away from the limiting block 8 is designed with a tooth shape. By designing the outer wall of the end of the threaded rod 15 away from the limiting block 8 with a tooth shape, it is convenient to operate the threaded rod 15 to rotate. The rotation of the threaded rod 15 forms a relative displacement with the fixing plate 16. With the connection of the bearing, the side roller 18 can be pushed to move.

[0038] Reference Figure 5 The upper surface of the cutting table 3 has limit grooves 4 on both sides, and the lower surface of the feeding plate 6 has toothed plates 5 fixedly connected to both sides. The bottom end of the toothed plate 5 is slidably engaged in the limit groove 4 corresponding to its position. The length of the feeding plate 6 is equal to the length of the toothed plate 5. Through its design, when the toothed plate 5 moves along the limit groove 4, it can limit the movement of the feeding plate 6, so that it can move smoothly along the cutting table 3 and prevent it from deviating.

[0039] Reference Figure 6The transmission mechanism includes a connecting rod 20 housed in a main seat 2. The main seat 2 has two receiving slots 22. Both ends of the connecting rod 20 are fixedly connected to gears 21 located in the two receiving slots 22 respectively. The gears 21 are used to mesh with the gear plate 5. A sleeve block 19 is fixedly connected in the main seat 2. The connecting rod 20 is movably sleeved in the sleeve block 19. A servo motor 23 is fixedly installed in one of the receiving slots 22. The output shaft of the servo motor 23 is fixedly connected to one of the gears 21. Through this design, the connecting rod 20, gears 21 and servo motor 23 in the transmission mechanism can be hidden and housed in the main seat 2, so that the main seat 2 has good integrity and makes the connection between the various parts of the transmission mechanism tight, compact in structure, and with better safety and stability.

[0040] Reference Figure 5 and Figure 7 Guide grooves 24 are provided on both sides of the upper surface of the main seat 2. The positions of the two guide grooves 24 correspond to the positions of the two tooth plates 5 respectively, and one end of the tooth plate 5 is slidably engaged in the guide groove 24 through the limiting slide groove 4.

[0041] Reference Figure 7 A baffle 25 is fixedly connected to the upper front surface of the feeding plate 6, and the length of the baffle 25 is greater than the width of the feeding plate 6. A soft pad layer 26 for contacting the extruded board is bonded to the inner wall of the baffle 25. By setting the baffle 25 on the feeding plate 6, the extruded board can be blocked and limited, preventing the extruded board from detaching from the feeding plate 6 during the process of the feeding plate 6 moving the extruded board. The soft pad layer 26 set on the inner wall of the baffle 25 can be made of soft rubber or sponge, so that the baffle 25 can form a soft contact with the extruded board, preventing scratches to the extruded board.

[0042] Reference Figure 9 and 10The cutting mechanism includes a cutting frame 27 with a touch panel 28 at the front end, which is mounted directly above the cutting table 3. The cutting frame 27 contains a hydraulic lifting head 34 with a cutter at the bottom. Fixed connecting plates 30 are fixedly connected to both sides of the tail end of the hydraulic lifting head 34. A second support frame 29 located at the tail end of the cutting frame 27 is fixedly connected to the upper surface of the cutting table 3. Hollow cavities 32 with internal hollow designs are fixedly connected to both sides of the lower surface of the second support frame 29. A push rod 31 is fixedly connected to the bottom of the fixed connecting plate 30. The bottom end of the push rod 31 slides through the second support frame 29 and is located within the hollow cavity 32. The bottom end of the push rod 31 is fixedly connected to the outer wall of the push rod 31 and the inner wall of the hollow cavity 32. The piston block 35 fits into the cavity 32, and an inner support plate 36 is slidably sleeved inside the cavity 32. A bottom rod 37 is fixedly connected to the top of the inner support plate 36, and a pressure plate 33 with a diameter larger than that of the cavity 32 is fixedly connected to the top of the bottom rod 37. Two limiting springs 38 are fixedly connected between the bottom of the inner support plate 36 and the bottom of the inner wall of the cavity 32. Through its design, before the cutter cuts the extruded board, the pressure plate 33 moves synchronously with the cutter, and its position is lower and descends first before the cutter. It can squeeze and limit the two sides of the other end of the extruded board. Furthermore, it pushes the pressure plate 33 down by air pressure, so that the pressure plate 33 has good elastic expansion and contraction performance, preventing excessive compression of the extruded board and causing it to break.

[0043] Reference Figure 8 The upper surface of the cutting table 3 is fixedly connected to a fixing frame 39 located behind the cutting frame 27, and a number of soft sheets 40 are fixedly connected to the top of the inner wall of the fixing frame 39. The bottom of the soft sheets 40 overlaps with the upper surface of the cutting table 3. Through its design, it can prevent the extruded board from falling off the cutting table 3 when it is pulled out.

[0044] In use, the extruded polystyrene board to be cut is first placed flat on the loading plate 6, and arranged neatly using the baffle 25. The servo motor 23 is started, driving the gear 21 to rotate. The connecting rod 20 causes the two gears 21 to rotate synchronously, and the gears 21 mesh with the two toothed plates 5, causing the toothed plates 5 to move the connected loading plate 6 stably towards the cutting frame 27. When the loading plate 6 carrying the extruded polystyrene board to be cut enters below the first support frame 7, the limiting blocks 8 on both sides of the lower part of the first support frame 7 limit the loading plate 6. The side rollers 18 on one side of the inner wall of the limiting block 8 contact the edge of the extruded polystyrene board, and the two corresponding side rollers 18 limit the two sides of the extruded polystyrene board to keep it neat. The threaded rod 15 is rotated to move and extend, driving the side rollers 18 to move and adjust their distance to accommodate wider extruded polystyrene boards. At that time, the extruded board on the feeding plate 6 comes into contact with the outer roller 12 on the inner wall of the limiting block 8. The outer roller 12 rolls under force and the extruded board pushes the outer roller 12 onto the extruded board, causing the outer roller 12 to drive the measuring rod 9 connected to its top to move upward. The distance it moves upward is the thickness of the extruded board. The distance it extends can be observed through the scale line layer 11 on the measuring rod 9. The outer roller 12 squeezes and limits the extruded board under the elastic compression of the support spring 13. Secondly, when one of the measuring rods 9 is pushed up by the extruded board, the distance sensing mechanism 10 corresponding to the measuring rod 9 senses the distance it moves and feeds the signal back to the touch panel 28 on the cutting frame 27. The touch panel 28 receives feedback and adjusts the initial height position and cutting force of the cutter before cutting to adapt it to the thickness of the extruded board for accurate and stable cutting.

[0045] When the feeding plate 6 moves completely under the cutting frame 27, one end of the extruded board on the feeding plate 6 is limited by two outer rollers 12, and the servo motor 23 is turned off to stop the feeding plate 6 from moving. Then, the hydraulic lifting head 34 in the first support frame 7 automatically descends, driving the cutter at the bottom of the hydraulic lifting head 34 to descend. At the same time as the hydraulic lifting head 34 descends, the push rod 31 is driven to descend synchronously through the fixed connecting plate 30 connected to it. The descending push rod 31 uses the piston block 35 to compress the air in the cavity 32 and pushes the inner support plate 36 to descend. The descending inner support plate 36 drives the pressure plate 33 connected to the bottom rod 37 to descend synchronously. Before the cutter cuts the extruded board, the pressure plate 33 moves synchronously with the cutter, and its position is lower and takes priority over the descending cutter to compress and limit both sides of the other end of the extruded board, so that both sides of the extruded board are pressed to prevent slippage. Finally, the cutter cuts the extruded board.

[0046] After the extruded polystyrene board is cut, the hydraulic lifting head 34 automatically rises and lifts up, while the pressure plate 33 automatically lifts up and resets under the action of the limit spring 38 for the next use. The servo motor 23 is started to drive the gear 21 to rotate, and the gear 21 meshes with the two toothed plates 5, so that the toothed plates 5 drive the connected feeding plate 6 to move. After the feeding plate 6 moves backward and protrudes a certain distance from the cutting frame 27, the extruded polystyrene board on the feeding plate 6 is removed. Then, the output shaft of the servo motor 23 is started to reverse and drive the feeding plate 6 to move back to the initial position for the next feeding of extruded polystyrene board for cutting.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
