[0002] After the foam board is formed, temperature changes or continuous stress may cause the foam board to expand or contract, resulting in warping, cracking and other problems. In order to ensure the structural stability of the foam board and to improve the local flexibility of the foam board, it is usually necessary to trim the formed foam board, such as grooving the foam board.

[0003] A slotting machine is usually used for trimming and slotting of foam boards. The tool on the slotting machine is generally set with a CNC program to move along a trajectory, thereby forming a groove with a preset trajectory on the surface of the foam board. In order to ensure that the groove is opened at the preset position of the foam board, the position of the foam board needs to be adjusted before slotting, so that the area to be processed of the foam board is aligned with the moving path of the tool.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Please also read Figures 1 to 6 , the foam board trimming and grooving device of the present invention is described. A foam board trimming and grooving device comprises a workbench 10, a positioning unit 20, a plurality of abutting units 30 and a cutting unit (not shown), the positioning unit 20 comprises a fixing member and a fixing rope 201, the fixing member is provided with a plurality of fixing members and is detachably connected to the workbench 10, the fixing member has an inner side facing the foam board and an outer side away from the foam board, the fixing rope 201 sequentially passes around the outer sides of all the fixing members and encloses to form a closed area for placing the foam board; the plurality of abutting units 30 are sequentially arranged along the length direction of the fixing rope 201, the abutting units 30 comprise a connecting ring 301, a contact plate 302 and a side top member 303 fixed between the connecting ring 301 and the contact plate 302, the connecting ring 301 is sleeved on the outer periphery of the fixing rope 201, the connecting ring 301 is detachably connected to the fixing rope 201, and the contact plate 302 abuts against the foam board; the cutting unit is connected to the workbench 10, and is used for cutting and grooving the foam board.

[0021] Specifically, the side top member 303 can be a telescopic cylinder, a hydraulic cylinder, or an electric cylinder.

[0022] It should be noted that the cutting unit is an existing grooving device, which will not be elaborated in this application.

[0023] For the foam board trimming and grooving device provided in this embodiment, the staff fixes a plurality of fixing members at preset positions on the workbench 10, so that the shape of the figure formed by the plurality of fixing members is the same as the shape of the foam board to be trimmed. Then, the staff connects a plurality of pressing units 30 to the fixing ropes 201, and then bypasses the fixing ropes 201 around the fixing members, thereby evenly distributing the pressing units 30 according to the shape of the foam board to be trimmed. Finally, the staff places the foam board to be trimmed into the enclosed area. After the foam board is placed in the enclosed area, the side pressing member 303 is activated to extend the contact plate 302 by the same distance, ensuring that the foam board is located at the center of the enclosed area, so that the area to be processed of the foam board and the walking path of the tool are consistent.

[0024] Compared with the prior art, any figure can be arranged through the fixing members, so that the grooving machine is applicable to foam boards of different shapes, and for trimming foam boards of the same batch, only the position of the enclosed area formed by the fixing ropes 201 needs to be calibrated once, without the need to calibrate the position of the foam board multiple times, saving time and improving work efficiency.

[0025] In one embodiment, refer to Figure 2 and Figure 3 , the fixing member includes a pressing block 202, a connecting block 203, a moving rod 204, a transmission block 205, a moving plug 206 and a telescopic member 207. The pressing block 202 is arranged above the workbench 10. A transmission cavity 2021 is recessed on the bottom wall of the pressing block 202, and a spiral transmission groove 2022 is provided on the inner wall of the transmission cavity 2021; the connecting block 203 is arranged between the pressing block 202 and the workbench 10, and the connecting block 203 abuts against the workbench 10. A negative pressure cavity 2031 is recessed inward on the bottom wall of the connecting block 203, and an air hole 2032 communicating with the outside is opened on the inner wall of the negative pressure cavity 2031. A sealing plug 20321 is connected in the air hole 2032, and a through hole 2033 communicating with the outside is opened on the top wall of the negative pressure cavity 2031; one end of the moving rod 204 is inserted into the transmission cavity 2021, and the other end passes through the through hole 2033 and extends into the negative pressure cavity 2031; one end of the transmission block 205 is inserted into the transmission groove 2022, and the other end is fixedly connected to the outer wall of the moving rod 204; the moving plug 206 is arranged in the negative pressure cavity 2031 and is fixedly connected to the moving rod 204; the telescopic member 207 is fixedly arranged between the pressing block 202 and the connecting block 203, and the telescopic member 207 expands and contracts along the axial direction of the moving rod 204.

[0026] Specifically, the telescopic member 207 can be a telescopic oil cylinder, a hydraulic cylinder or an electric cylinder. A storage cavity 2023 for storing the telescopic member 207 is opened on the bottom wall of the pressing block 202.

[0027] Optionally, the sealing plug 20321 is in interference connection with the air hole 2032.

[0028] Optionally, the sealing plug 20321 is in threaded connection with the air hole 2032.

[0029] The staff holds the connecting block 203 to make the connecting block 203 close to the workbench 10. At this time, the telescopic member 207 is activated to drive the pressing block 202 to move downward and gradually approach the connecting block 203. The downward movement of the pressing block 202 drives the moving rod 204 to move upward through the relative sliding of the transmission groove 2022 and the transmission block 205, and the moving rod 204 rotates around its own central axis. As a result, while the moving plug 206 moves upward, it rotates with the up-down direction as the rotation axis, increasing the space below the moving plug 206. However, the amount of gas below the moving plug 206 remains unchanged, thereby reducing the air pressure below the moving plug 206, making the air pressure below the moving plug 206 less than the external air pressure, so as to adsorb and fix the connecting block 203 to the workbench 10.

[0030] When it is necessary to remove the fixing member from the workbench 10, the staff only needs to pull out the sealing plug 20321 in the air hole 2032. After the sealing plug 20321 is pulled out, the negative pressure chamber 2031 is communicated with the outside, making the air pressure in the negative pressure chamber 2031 equal to the external air pressure, so that the connecting block 203 is separated from the workbench 10. Then the telescopic member 207 is activated to drive the pressing block 202 to move upward, and the upward movement of the pressing block 202 makes the moving plug 206 move downward to reset.

[0031] In one embodiment, refer to Figure 2 , the moving rod 204 includes a translation section 2041 and a rotation section 2042. The translation section 2041 is slidably disposed in the through hole 2033, and the translation section 2041 moves in the up-down direction; the rotation section 2042 is disposed in the transmission cavity 2021, the bottom end of the rotation section 2042 is rotatably connected to the translation section 2041, the rotation section 2042 rotates with the up-down direction as the rotation axis, and the transmission block 205 is fixedly connected to the rotation section 2042.

[0032] While the staff presses down the pressing block 202, the transmission block 205 slides in the transmission groove 2022, making the rotation section 2042 rotate around its own central axis and move upward. The upward movement of the rotation section 2042 drives the translation section 2041 to move upward. Since the rotation section 2042 and the translation section 2041 are rotatably connected, and the translation section 2041 is restricted to slide only in the up-down direction, the rotation section 2042 can only drive the translation section 2041 to move upward. Thus, the translation section 2041 drives the moving plug 206 to move upward, so that the moving plug 206 does not rotate during the upward movement, reducing the friction between the moving plug 206 and the inner wall of the negative pressure chamber 2031.

[0033] In one embodiment, refer toFigure 1 and Figure 4 The positioning unit 20 further includes a moving seat 208, a spool 209, and a driving member 210. The moving seat 208 is slidably connected to one side of the workbench 10, and the moving seat 208 is detachably connected to the workbench 10; the spool 209 is rotatably connected to the moving seat 208, and the fixing rope 201 is wound around the outer periphery of the spool 209. One end of the fixing rope 201 is fixedly connected to the spool 209, and the other end of the fixing rope 201 is detachably connected to the workbench 10; the driving member 210 is disposed on the moving seat 208, and the driving member 210 is in transmission connection with the spool 209 for driving the spool 209 to rotate with the vertical direction as the rotation axis.

[0034] Specifically, the driving member 210 is a motor, and the output shaft of the driving member 210 is directly fixed to the spool 209.

[0035] The staff can move the position of the spool 209 by sliding the moving seat 208. After moving the spool 209 to a preset position, the spool 209 is fixed on the workbench 10 by fixing the moving seat 208 to the workbench 10; after the position of the spool 209 is determined, the staff starts the driving member 210, and the driving member 210 drives the spool 209 to rotate, thereby releasing the fixing rope 201 of the required length. When calibrating different-shaped foam boards, the required lengths of the fixing rope 201 are different. Therefore, by adjusting the length of the fixing rope 201, different-shaped foam boards can be matched, improving the application range of the device.

[0036] In one embodiment, referring to Figure 1 , a sliding rod 101 is fixedly connected to one side of the workbench 10. The sliding rod 101 is parallel to the edge of the workbench 10. The moving seat 208 is sleeved on the sliding rod 101 and the two are slidably adapted. The moving seat 208 is provided with an adsorption part; wherein, the adsorption part is electrified and adsorbed and fixed to the sliding rod 101, and the adsorption part is powered off and separated from the sliding rod 101.

[0037] Optionally, the adsorption part is an electromagnet, and the sliding rod 101 is made of ferromagnetic material.

[0038] Optionally, the adsorption part is an electric vacuum chuck.

[0039] After the staff moves the moving seat 208 to a preset position, the adsorption part starts to be electrified so that the moving seat 208 is adsorbed and fixed to the sliding rod 101; when the position of the moving seat 208 needs to be adjusted, the adsorption part is powered off, and at this time the adsorption part is separated from the sliding rod 101, so that the position of the moving seat 208 can be arbitrarily moved on the sliding rod 101.

[0040] In one embodiment, referring to Figure 5, a connection groove 2034 is formed on the outer wall of the connection block 203. A limiting rod 2035 passes through the connection block 203. The axial direction of the limiting rod 2035 is parallel to the axial direction of the moving rod 204. The top end of the limiting rod 2035 is fixedly connected to the pressing block 202, and the bottom end of the limiting rod 2035 extends into the connection groove 2034; a connection buckle 2011 adapted to be inserted into the bottom end of the limiting rod 2035 is fixedly provided at the free end of the fixing rope 201.

[0041] It should be noted that the free end of the fixing rope 201 is fixedly connected to the first fixing member (the fixing member that the fixing rope 201 first bypasses).

[0042] Before fixing the first fixing member to the workbench 10, the staff grasps the free end of the fixing rope 201. First, insert the connection buckle 2011 into the connection groove 2034, then put the connection buckle 2011 on the limiting rod 2035. Then the staff presses the pressing block 202 on the first fixing member. The pressing block 202 moves downward to drive the limiting rod 2035 to move downward until the bottom of the limiting rod 2035 abuts against the inner bottom wall of the connection groove 2034, thereby fixing the fixing rope 201 in the connection groove 2034. Through the above structure, while fixing the first fixing member to the workbench 10, the free end of the fixing rope 201 is connected and fixed to the first fixing member; when the first fixing member is separated from the workbench 10, the free end of the fixing rope 201 disengages from the connection groove 2034.

[0043] In one embodiment, see Figure 5 , a positioning groove 2036 adapted to be inserted into the limiting rod 2035 is formed on the inner bottom wall of the connection groove 2034.

[0044] The limiting rod 2035 moves downward and inserts into the positioning groove 2036, thereby enhancing the fixing strength of the connection buckle 2011, making it difficult for the connection buckle 2011 to disengage from the connection groove 2034, and ensuring the connection strength between the free end of the fixing rope 201 and the first fixing member.

[0045] In one embodiment, see Figure 2 , a limiting groove 2037 for the fixing rope 201 to be embedded is formed on the outer side of the connection block 203.

[0046] When the staff winds the fixing rope 201 around the fixing member, the fixing rope 201 can be stuck in the limiting groove 2037, so that the fixing rope 201 will not have a relative displacement in the vertical direction with respect to the fixing member. Thus, the fixing rope 201 always remains parallel to the tabletop of the workbench 10, so that the distances between all the pressing units 30 and the workbench 10 are kept consistent. Thereby, it is ensured that the contact positions of the contact plates 302 with the foam board are at the same height, avoiding uneven stress on the foam board and further reducing damage to the foam board.

[0047] In one embodiment, a flexible pad (not shown) is fixedly connected to the bottom wall of the connecting block 203.

[0048] The flexible pad at the bottom can better create a sealed environment, enhance the tightness of the negative pressure chamber 2031, and thus enhance the connection strength between the fixing member and the workbench 10.

[0049] In one embodiment, referring to Figure 6 , an airbag 3011 and an inflating member (not shown) communicating with the airbag 3011 are fixedly connected to the inner wall of the connecting ring 301, and the airbag 3011 is sleeved on the outer periphery of the fixing rope 201.

[0050] Specifically, the inflating member is an air pump.

[0051] After the staff sleeved the connecting ring 301 on the fixing rope 201 and moved it to a preset position, the inflating member was activated to inflate the airbag 3011, so that the airbag 3011 tightly wrapped the fixing rope 201, thereby fixing the connecting ring 301 to the fixing rope 201. The airbag 3011 will not cause damage to the fixing rope 201 during the process of wrapping the fixing rope 201, prolonging the service life of the fixing rope 201 and saving costs.

[0052] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
