Description

Technical Field

[0001] This utility model relates to the field of sign cutting technology, and in particular to a fiberglass sign cutting machine. Background Technology

[0002] Fiberglass signs are signs made of fiberglass reinforced plastic (FRP). Fiberglass is a lightweight, high-strength composite material with good corrosion resistance, weather resistance, impact resistance, and insulation properties. Therefore, it is widely used in outdoor and industrial environments. Fiberglass sign cutting machines are mechanical devices used to cut fiberglass sign sheets.

[0003] The existing fiberglass sign panels require manual centering and adjustment by workers before cutting can proceed. This adjustment process is inconvenient and the accuracy is questionable. Furthermore, existing fiberglass sign panels are generally custom-designed and can only be cut for a single type of fiberglass sign, limiting their application. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a fiberglass sign cutting machine. It improves the existing fiberglass sign cutting machine, which requires workers to manually center and adjust the position of the sheet before the subsequent cutting process can be carried out. The overall adjustment process is inconvenient and the accuracy needs to be tested. At the same time, the existing fiberglass sign sheets are generally custom-designed and can only be cut for a single type of fiberglass sign, which limits the scope of application.

[0005] A fiberglass sign cutting machine includes a support base, a positioning support frame, a cutting control mechanism, a centering limit mechanism, and a blade replacement assembly: four sets of ear plates for positioning the entire device are circumferentially distributed on the outer side wall of the support base at the bottom end, and a positioning support frame is provided on the outer top wall of the support base, the positioning support frame being configured as an "n" shaped structure.

[0006] The cutting control mechanism includes an electric cylinder, a support plate, an auxiliary mounting plate, and a square cutting blade. The electric cylinder is fixed above the positioning support frame, and the output end of the electric cylinder passes through the positioning support frame and is connected to the top outer wall of the support plate. The auxiliary mounting plate is fitted to the bottom outer wall of the support plate, and the square cutting blade is fixedly installed on the bottom outer wall of the auxiliary mounting plate.

[0007] Preferably, the centering limiting mechanism includes a support base, a limiting cylinder, a limiting piston rod, and a contact spring. The top outer wall of the support base is symmetrically provided with support bases. Both sets of support bases are configured as inverted "L"-shaped structures, and the inner side walls of the support bases are equally spaced and embedded with limiting cylinders. The limiting piston rod is slidably installed inside the limiting cylinder, and a contact spring is connected between the outer side wall of the limiting piston rod and the inner bottom wall of the limiting cylinder.

[0008] Preferably, the protruding end of the limiting piston rod is located outside the limiting cylinder, and the protruding end of the limiting piston rod is connected to the outer side wall of the contact plate.

[0009] Preferably, both outer walls of the contact plate are chamfered.

[0010] Preferably, the blade replacement assembly includes abutment blocks and abutment slots. Two sets of abutment blocks are symmetrically arranged on the top outer wall of the auxiliary mounting plate. Both sets of abutment blocks are set in an "I" shape, and two sets of abutment slots for engaging and installing the abutment blocks are correspondingly opened on the bottom outer wall of the support plate.

[0011] Preferably, the outer side wall of the contact block is symmetrically provided with two sets of first threaded grooves, and the outer side wall of the support plate located at the contact groove is provided with a corresponding second threaded groove, and the first threaded groove and the second threaded groove are threadedly installed with the fastening bolt.

[0012] The beneficial effects of this utility model are:

[0013] 1. When using this fiberglass sign cutting machine, the design of two sets of spring-loaded contact components facing each other on the top of the device allows the fiberglass sign sheet to be automatically centered when pushed to the middle position of the two sets of spring-loaded contact components. This eliminates the need for operators to repeatedly adjust the position of the sheet for centering, thus providing a basic guarantee for the accuracy of subsequent sheet cutting processes while ensuring the stability of the sheet's centering position. The overall structure is ingeniously designed and has good practical effect.

[0014] 2. When using this fiberglass sign cutting machine, the locking effect of the locking block assembly and bolt assembly makes the built-in cutting blade detachable. This facilitates the maintenance and cleaning of the blade assembly and allows for the installation of die-cutting blades of different shapes to meet the cutting needs of various signs. The overall structure is flexible and has good practical effect. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In practical implementation: such as Figure 1-5 As shown, a fiberglass sign cutting machine includes a support base 1, a positioning support frame 2, a cutting control mechanism 3, a centering limit mechanism 4, and a blade replacement assembly 5. The support base 1 has four sets of ear plates for positioning the entire device installed circumferentially on the outer side wall at the bottom position, and the top outer wall of the support base 1 is provided with a positioning support frame 2, which is set as an "n" shaped structure.

[0023] The cutting control mechanism 3 includes an electric cylinder 31, a support plate 32, an auxiliary mounting plate 33, and a square cutting blade 34. The electric cylinder 31 is fixed above the positioning support frame 2, and the output end of the electric cylinder 31 passes through the positioning support frame 2 and is connected to the top outer wall of the support plate 32. The auxiliary mounting plate 33 is fitted to the bottom outer wall of the support plate 32, and the square cutting blade 34 is fixedly installed on the bottom outer wall of the auxiliary mounting plate 33.

[0024] When it is necessary to die-cut the positioned signboard material into the shape of a square signboard, it is only necessary to control the electric cylinder 31 to open. When the electric cylinder 31 is opened, its output end automatically extends and synchronously drives the support plate 32 to move down. Then, the support plate 32 moves down and automatically drives the auxiliary mounting plate 33 to move down and synchronously drives the square cutting blade 34 to move down. As the square cutting blade 34 moves down, the die-cutting process of the signboard material is automatically completed.

[0025] The centering limiting mechanism 4 includes a support base 41, a limiting cylinder 42, a limiting piston rod 43, and a contact spring 44. The top outer wall of the support base 1 is symmetrically provided with support bases 41. Both sets of support bases 41 are configured as inverted "L" shaped structures. The inner side wall of the support base 41 is equally spaced and embedded with the limiting cylinder 42. The limiting piston rod 43 is slidably installed inside the limiting cylinder 42. The outer side wall of the limiting piston rod 43 is connected to the inner bottom wall of the limiting cylinder 42 with a contact spring 44. The protruding end of the limiting piston rod 43 is located outside the limiting cylinder 42 and is connected to the outer side wall of the contact plate 45.

[0026] When it is necessary to center and limit the movement of the signboard material to be cut, the signboard material must first be pushed horizontally to the middle position of the two sets of contact plates 45. Then, the two sets of contact plates 45 will move backward under the pressure of the signboard material, providing a certain space for the signboard material to be placed. When the contact plates 45 move backward, they will automatically drive the limiting piston rod 43 to slide inside the limiting cylinder 42. Refer to the instruction manual. Figure 4 As shown, the limiting cylinder 42 is pre-filled with damping fluid, and the limiting piston rod 43 has through-holes at equal intervals on the outer side wall of the piston plate for the flow of damping fluid. When the limiting piston rod 43 slides inside the limiting cylinder 42, the damping fluid inside the limiting cylinder 42 will move along the movement trajectory of the limiting piston rod 43 and flow through the through-holes inside the limiting cylinder 42. At the same time, the contact spring 44 is compressed by the squeezing action of the limiting piston rod 43 and simultaneously generates a reaction force, which pushes the limiting piston rod 43 to move in the opposite direction. When the limiting piston rod 43 moves in the opposite direction, it will automatically push the contact plate 45 to move and make it tightly contact the outer side wall of the sign plate. Thus, through the contact effect of the two sets of contact plates 45 and the restriction of the placement groove formed by the support base 41 itself, the sign plate can be stably positioned in the center above the device.

[0027] Both outer walls of the contact plate 45 are chamfered; this chamfer design makes it easier to push the signboard material to the two sets of contact plates 45.

[0028] The blade replacement assembly 5 includes abutment blocks 51 and abutment slots 52. Two sets of abutment blocks 51 are symmetrically arranged on the top outer wall of the auxiliary mounting plate 33. Both sets of abutment blocks 51 are set in an "I" shape. The bottom outer wall of the support plate 32 is correspondingly provided with two sets of abutment slots 52 for engaging and installing the abutment blocks 51. The side outer wall of the abutment blocks 51 is symmetrically provided with two sets of first threaded grooves 53. The side outer wall of the support plate 32 located at the position of the abutment slots 52 is correspondingly provided with second threaded grooves 54. The first threaded grooves 53 and the second threaded grooves 54 are threadedly installed with the fastening bolts 55.

[0029] When the square cutter 34 wears down due to repeated use and needs to be replaced, firstly, the fastening bolt 55 needs to be completely unscrewed from the inside of the first threaded groove 53, so that the abutment block 51 changes from the locked state to the movable state. Then, simply pull down the auxiliary mounting plate 33 to remove the square cutter 34 from the device. When installing a new square cutter 34, you also need to hold the auxiliary mounting plate 33 and insert the abutment block 51 at its upper end into the corresponding abutment groove 52. When the abutment block 51 is fully inserted into the abutment groove 52, the positions of the first threaded groove 53 and the second threaded groove 54 are in a corresponding overlapping state. Then, simply use the fastening bolt 55 to pass through the first threaded groove 53 and tighten the bottom of the second threaded groove 54 to complete the installation process of the new square cutter 34.

[0030] In use, the signboard material to be cut first needs to be centered and positioned against the contact plate. This is done by pushing the signboard material horizontally to the middle position of the two sets of contact plates 45. The two sets of contact plates 45 then move backward under the pressure of the signboard material, providing space for its placement. As the contact plates 45 move backward, they automatically drive the limiting piston rod 43 to slide inside the limiting cylinder 42. (Refer to the attached instruction manual.) Figure 4 As shown, the limiting cylinder 42 is pre-filled with damping fluid, and the limiting piston rod 43 has through slots at equal intervals on the outer side wall of the piston plate for the flow of damping fluid. When the limiting piston rod 43 slides inside the limiting cylinder 42, the damping fluid inside the limiting cylinder 42 will move along the movement trajectory of the limiting piston rod 43 and flow through the through holes inside the limiting cylinder 42. At the same time, the contact spring 44 is compressed by the squeezing action of the limiting piston rod 43 and generates a reaction force, which pushes the limiting piston rod 43 to move in the opposite direction. When the limiting piston rod 43 moves in the opposite direction, it will automatically push the contact plate 45 to move and make it tightly contact the outer side wall of the sign plate. Thus, through the contact effect of the two sets of contact plates 45 and the restriction of the placement groove formed by the support base 41 itself, the sign plate can be stably positioned in the center above the device.

[0031] The positioned signboard material is then die-cut into the shape of a square signboard. At this point, it is only necessary to control the electric cylinder 31 to open. When the electric cylinder 31 is opened, its output end automatically extends and simultaneously drives the support plate 32 to move down. The downward movement of the support plate 32 will automatically drive the auxiliary mounting plate 33 to move down and simultaneously drive the square cutting blade 34 to move down. As the square cutting blade 34 moves down, the die-cutting process of the signboard material is automatically completed. After a single die-cutting is completed, the signboard material is pushed forward along the horizontal side to carry out subsequent die-cutting processes.

[0032] It should be noted here that the electric cylinder 31 mentioned above can be operated in accordance with existing operating techniques, whether it is powered by a power supply device or by an external wire. These are all existing conventional operating techniques and will not be described in detail here.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
