Description

Technical Field

[0001] The present invention relates to the field of clamping devices, and more specifically, to a clamping device for trimming the edges of epoxy glass fiber cloth insulating boards. Background Art

[0002] Fiberglass board, also known as glass fiber board, is generally used for the soft package base layer, and then covered with fabric, leather, etc. on the outside to make beautiful wall and ceiling decorations. It has a very wide range of applications. It has the characteristics of sound absorption, sound insulation, heat insulation, environmental protection, flame retardancy, etc. The alias of glass fiber board: glass fiber heat insulation board, fiberglass board, glass fiber composite board, which is synthesized from glass fiber materials and high heat-resistant composite materials, and does not contain asbestos components harmful to the human body. It has high mechanical properties and dielectric properties, good heat resistance and moisture resistance, and good processability. It is used in plastic molds, injection molds, machinery manufacturing, molding machines, drilling machines, injection molding machines, motors, PCBs. ICT fixtures, table grinding pads. Injection mold forming usually requires: high-temperature materials and low-temperature molds. Under the same machine conditions, heat insulation methods must be adopted. Keep the injection mold at a low temperature while not making the temperature of the injection molding machine too high. Installing an insulating heat insulation board between the injection mold and the injection machine can meet this requirement. Shorten the production cycle, improve production efficiency, reduce energy consumption, improve the quality of finished products, and the continuous production process ensures the stable quality of products, prevents the machine from overheating, has no electrical faults, and the hydraulic system has no oil leakage.

[0003] The existing glass fiber cloth insulating board technology has the following problems: 1. When the existing glass fiber cloth insulating board is trimmed, it is easy for the cut-off materials at the edges and corners to adhere to the separated board due to the cutting of the material, resulting in the vibrating knife driving the cut-off materials at the edges and corners to curl or displace during the moving cutting process. As a result, during the cutting process, cutting errors may occur due to the offset of the cut-off materials at the edges and corners, leading to the phenomenon of material damage. 2. After the existing glass fiber cloth insulating board is cut, when it is stacked and placed on the conveyor belt in the later stage, it is easy for the two glass fiber cloth insulating boards to adsorb to each other because there are too many stacked, which will cause certain trouble for the user when separating them.

Detailed Embodiment

[0030] The following will describe the technical solutions in the embodiments of the present invention in clear and complete detail with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment:

[0032] Please refer to Figures 1-4 , a clamping device for trimming an epoxy glass fiber cloth insulating board, including a trimming table 100, a conveyor belt 200 is installed between the inner walls of the trimming table 100, support frames 300 are fixedly connected to both the left and right ends of the trimming table 100, a slide rail 400 is provided at the upper end of the support frame 300, a slider 500 is slidably connected between the inner walls of the slide rail 400, an adapter table 600 is fixedly connected to the upper end of the slider 500, a telescopic cylinder 700 is installed at the upper end of the adapter table 600, a cutting assembly 800 is provided at the upper end of the telescopic cylinder 700, and clamping assemblies 900 are provided at the upper ends of both the left and right sides of the trimming table 100.

[0033] When this solution is in use, to avoid the phenomenon that the cut-off material adheres to the separated plate during the trimming of the glass fiber cloth insulating board, which may cause the cut-off material to warp or displace when the vibrating knife moves for cutting, resulting in cutting errors due to the offset of the cut-off material during the cutting process and causing damage to the material. When the staff trims the glass fiber cloth insulating board, they can place the glass fiber cloth insulating board on the surface of the conveyor belt 200, and then through the set program, the cutting assembly 800 trims the glass fiber cloth insulating board below. During the trimming process, when the cutting assembly 800 moves downward for cutting, the cutting assembly 800 squeezes the clamping assembly 900 downward during its movement, causing the clamping assembly 900 to clamp the cut-off material of the glass fiber cloth insulating board placed on its surface, thereby firmly clamping the entire glass fiber cloth insulating board, avoiding the displacement of the glass fiber cloth insulating board caused by the adhesion of the cut-off material to the separated plate, making it more stable during the cutting process, and not easily having errors during the cutting process due to the displacement of the cut-off material resulting in material damage. After the cutting work is completed, since the cutting assembly 800 moves upward and is no longer cutting the glass fiber cloth insulating board and is located above it, along with the upward movement of the cutting assembly 800, the clamping assembly 900 is no longer stressed to clamp the cut-off material of the glass fiber cloth insulating board. The staff can operate the conveyor belt 200 to operate, driving the cut glass fiber cloth insulating board and the cut-off material to be conveyed backward, thereby completing the stacking and storage steps for the next cutting work of the glass fiber cloth insulating board.

[0034] Please refer to Figures 1-2 Figures 1-2 , the cutting assembly 800 includes an adapter plate 801 fixedly connected to the upper end of the telescopic cylinder 700. Two load-bearing blocks 802 symmetrically distributed up and down are fixedly connected to the front end of the adapter plate 801. A chute 803 is formed in the outer end of the load-bearing block 802. A rectangular plate 804 is slidably connected between the inner walls of the chute 803. The rectangular plate 804 is located on the front side of the load-bearing block 802. A vibrating knife 805 is installed at the front end of the rectangular plate 804. A control console 806 is installed at the upper end of the rectangular plate 804. An air pipe 807 is embedded between the control console 806 and the vibrating knife 805.

[0035] During the use of this solution, after the staff places the fiberglass cloth insulating board above the conveyor belt 200, the staff starts the cutting assembly 800 under a set program, causing the slider 500 to slide inside the slide rail 400 under a specific program, so as to drive the adapter plate 801 to an appropriate position above the fiberglass cloth insulating board. Then, the telescopic cylinder 700 moves telescopically downward, causing the vibrating knife 805 to be located on the surface of the fiberglass cloth insulating board. Subsequently, under the drive of the control console 806, the rectangular plate 804 slides inside the chute 803, so that the vibrating knife 805 can freely move in the horizontal axis direction of the fiberglass cloth insulating board, thereby cutting the fiberglass cloth insulating board with the vibrating knife 805, so as to complete the cutting work of the scraps of the fiberglass cloth insulating board.

[0036] Please refer to Figure 1 and Figures 3-4 Figures 3-4 , the clamping assembly 900 includes support bottom plates 901 embedded in the upper end surfaces of the left and right sides of the trimming table 100. Four receiving grooves 902 are formed in the upper end of the trimming table 100. The receiving grooves 902 are respectively located on the front and rear sides of the support bottom plates 901. A pressing block 903 is slidably connected between the inner walls of the receiving grooves 902. A tension spring 904 is fixedly connected between the pressing block 903 and the inner bottom end of the receiving groove 902. A connecting rod 905 is fixedly connected to the upper end of the pressing block 903. A limiting plate 906 is fixedly connected to the upper end of the connecting rod 905. A groove 907 is formed in the upper end of the limiting plate 906. A clamping plate 908 is fixedly connected to the lower end of the limiting plate 906. The clamping plate 908 is located above the support bottom plate 901. A rectangular block 909 is fixedly connected to the lower end of the adapter plate 801. The diameter dimension of the rectangular block 909 is in line with the inner diameter of the groove 907. An anti-adhesion assembly 1000 is provided at the inner bottom end of the groove 907.

[0037] When this solution is in use, when the cutting assembly 800 moves downward to cut the fiberglass cloth insulating board, since the corners of the fiberglass cloth insulating board are placed above the support bottom plate 901 and the main material is placed above the conveyor belt 200, when the cutting assembly 800 moves downward, the rectangular block 909 on the lower side of the cutting assembly 800 just moves into the groove 907. Under the action of the downward pressure of the cutting assembly 800, the limiting plate 906 drives the pressing block 903 to move downward, so that the tension spring 904 is compressed and deformed. At the same time, the clamping plate 908 presses the corners of the fiberglass cloth insulating board, so as to stabilize the overall cutting of the fiberglass cloth insulating board, avoid the phenomenon that the fiberglass cloth insulating board is displaced due to the adhesion of the scrap and the separated plate during cutting, make it more stable during the cutting process, and not easily cause errors during cutting due to the displacement of the scrap resulting in material damage. Along with the cutting assembly 800 moving in the longitudinal axis direction to cut the fiberglass cloth insulating board, the rectangular block 909 moves in the longitudinal axis direction in the groove 907 while not affecting the pressing of the corners of the fiberglass cloth insulating board, so as to complete the movement of the fiberglass cloth insulating board in the longitudinal axis direction. Until the cutting work is completed, the cutting assembly 800 moves upward, causing the clamping plate 908 not to press the fiberglass cloth insulating board anymore. The conveyor belt 200 drives the cut fiberglass cloth insulating board to move backward, prompting the next uncut fiberglass cloth insulating board to move to the upper side of the support bottom plate 901, and then clamping and cutting work is carried out again.

[0038] Please refer to Figures 4-7 , the anti-adhesion assembly 1000 includes a threaded groove 1001 opened at the inner bottom end of the groove 907. A lower spherical shell 1002 is threadedly connected between the inner walls of the threaded groove 1001. A rubber sleeve 1003 is provided at the upper end of the lower spherical shell 1002. A blocking ball 1004 is fixedly connected to the inner top end of the rubber sleeve 1003. A lubricating fluid 1005 is filled between the lower spherical shell 1002 and the rubber sleeve 1003. A through hole 1006 is opened at the lower end of the lower spherical shell 1002. An anti-permeation membrane 1007 is installed between the inner walls of the through hole 1006. A first communication hole 1008 is opened at the lower end of the threaded groove 1001. A second communication hole 1009 is opened at the upper end of the clamping plate 908. The second communication hole 1009 communicates with the first communication hole 1008. An adsorption sponge 1010 is installed between the inner walls of the second communication hole 1009. The adsorption sponge 1010 is on the same horizontal plane as the lower end surface of the clamping plate 908.

[0039] The lower end of the rubber sleeve 1003 is fixedly connected with a threaded collar. The rubber sleeve 1003 is threadedly connected to the upper end of the lower spherical shell 1002 through the threaded collar, and the inner wall formed by the lower spherical shell 1002 and the rubber sleeve 1003 and the anti-permeation membrane 1007 form a closed airtight chamber.

[0040] The anti-permeation membrane 1007 is made using the principle of a heart valve and is the same as the principle of a bicycle valve stem. When the anti-permeation membrane 1007 is in its initial form and not under force, it is in a gathered and closed state, and when the anti-permeation membrane 1007 is under external force, it is in an open and closed state.

[0041] When this solution is in use, to avoid the phenomenon that after the fiberglass cloth insulating board is cut and transported on the conveyor belt 200 and stacked later, due to excessive stacking, the two fiberglass cloth insulating boards adsorb to each other, causing trouble for the user during separation. When the clamping component 900 clamps the surface of the fiberglass cloth insulating board and the cutting component 800 moves on the clamping component 900 for cutting, since the rectangular block 909 is always between the inner walls of the groove 907, when the rectangular block 909 slides to the upper side of the rubber sleeve 1003, the rubber sleeve 1003 is forced to deform and compress downward into the inner part of the lower spherical shell 1002. Then, since a closed chamber is formed between the lower spherical shell 1002 and the rubber sleeve 1003 and there is a certain pressure inside, when the rubber sleeve 1003 moves downward, due to the decrease in internal space and the increase in pressure, the pressure moves towards the anti-permeation membrane 1007. Subsequently, due to the principle of the heart valve, the anti-permeation membrane 1007 is forced to open and close, causing the lubricating fluid 1005 inside the lower spherical shell 1002 and the rubber sleeve 1003 to seep out from the through hole 1006 and flow towards the first communication hole 1008. Along with the continuous extrusion of the rectangular block 909 and when it is at the same horizontal level as the bottom end of the groove 907, the sphere formed by the lower spherical shell 1002 and the rubber sleeve 1003 deforms into a hemispherical shape. At this time, the plugging ball 1004 just plugs the through hole 1006 again, causing the lubricating fluid 1005 inside to leak only for a certain period under the action of pressure, avoiding the phenomenon of excessive leakage and rapid loss. When the rectangular block 909 leaves the upper side of the rubber sleeve 1003, due to the reset and rebound characteristics of the rubber sleeve 1003, the internal pressure of the lower spherical shell 1002 and the rubber sleeve 1003 returns to normal, and the anti-permeation membrane 1007 also returns to its initial closed state because it is no longer under pressure, plugging the lubricating fluid 1005. After the lubricating fluid 1005 leaks from the first communication hole 1008, it is received by the connected second communication hole 1009, causing the lubricating fluid 1005 to flow to the adsorption sponge 1010, thereby adsorbing it. As a result, the lubricating fluid 1005 adheres to the corners of the fiberglass cloth insulating board pressed by the clamping plate 908. When the fiberglass cloth insulating boards are stacked later, if adsorption occurs, the lubricating fluid 1005 adhered to the corners of the two fiberglass cloth insulating boards makes it more convenient for the operator to separate them, improving the work efficiency and also reducing the phenomenon of mutual adsorption of the fiberglass cloth insulating boards to a certain extent.

[0042] Meanwhile, under the action of the adsorption sponge 1010, the excessive lubricating fluid 1005 is accumulated to avoid excessive release above the fiberglass cloth insulating board at one time, which may affect the subsequent stacking and cause waste of resources. For example, in the case of continuous leakage of excessive lubricating fluid 1005, it can also be stored in the relatively long pipelines of the first communication hole 1008 and the second communication hole 1009. Later, with the adsorption of the adsorption sponge 1010 and the consumption during the adhesion to the fiberglass cloth insulating board, the lubricating fluid 1005 is replenished to ensure its full utilization rate.

[0043] When the lubricating fluid 1005 is consumed after long-term use, the operator can rotate the lower spherical shell 1002 to remove it from the thread groove 1001, and then penetrate the anti-permeation membrane 1007 with a syringe to complete the replenishment of the lubricating fluid 1005 in the inner cavities of the lower spherical shell 1002 and the rubber sleeve 1003.

[0044] And during the use process, if the leakage efficiency of the lubricating fluid 1005 is slow, the operator can further excavate the first communication hole 1008 according to the on-site situation, such as Figure 8 As shown, multiple first communication holes 1008 are opened, and the corresponding through holes 1006 and anti-permeation membranes 1007 are set to accelerate the leakage efficiency of the lubricating fluid 1005 caused by pressure when the rubber sleeve 1003 is squeezed, increase the leakage capacity, and make corresponding improvements to the blocking ball 1004 to enable the blocking ball 1004 to complete the blocking work of multiple through holes 1006 when moving downward.

[0045] Please refer to Figure 4 , the distribution positions of the storage grooves 902 are located on the front and back sides when the fiberglass cloth insulating board is placed, and the scraps of the fiberglass cloth insulating board are placed on the upper side of the support bottom plate 901.

[0046] In this solution, by locating the storage grooves 902 on the front and back sides when the fiberglass cloth insulating board is placed, it can prevent the fiberglass cloth insulating board from colliding with the connecting rod 905 during transmission on the conveyor belt 200, thus avoiding the occurrence of deviation in transmission.

[0047] A sealing ring is provided between the inner walls of the pressing block 903, and the sealing ring is made of rubber material.

[0048] In this solution, by setting a sealing ring between the inner walls of the pressing block 903, it can prevent impurities or dust in daily life from easily entering the interior of the storage groove 902, avoiding the influence of excessive internal impurities on the up and down contraction operation of the pressing block 903, and at the same time preventing the tension spring 904 from being eroded and reducing its service life.

[0049] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, making equivalent substitutions or changes according to the technical solution and its improved concept of the present invention, shall be covered by the protection scope of the present invention.
