Description

Technical Field

[0001] This utility model relates to the technical field of signboard edge grinding equipment, and in particular to a signboard edge grinding equipment. Background Technology

[0002] As a type of rigid material equipment with a reminder function, signs are prone to burrs, pits, and other defects at their edges and corners during production. To improve the aesthetics of signs, specialized edge grinding equipment is often used to grind these edges and corners.

[0003] To address this, patent specification CN222134406U discloses a sign production edge grinding device, including a clamp and a handle. The clamp is equipped with a sign production edge grinding component, which includes a grinding roller and a motor. The handle is equipped with a power component, which includes a battery and a switch. A support component is installed at the bottom of the clamp, including a support plate and a rotating roller. A pressing component is installed at the top of the clamp, including a pressure plate and a pressure roller. This sign production edge grinding device utilizes the friction between the rotating roller and the pressure roller to maintain stable pressure between the grinding roller and the sign's edge, avoiding both excessive grinding pressure that could damage the sign and insufficient grinding pressure that would reduce grinding efficiency. The friction between the grinding roller and the sign drives the clamp to move, automatically adjusting the grinding position without the need for gradual clamping and grinding, thus improving work efficiency. It is suitable for edge grinding of signs. The aforementioned sign corner polishing device has a good polishing effect when in use, but some problems still exist:

[0004] When using the aforementioned sign edge grinding device, it is often inconvenient to perform grinding treatment according to requirements because different sizes of signs have different grinding depths. Utility Model Content

[0005] The purpose of this invention is to provide a sign corner grinding device to solve the problem that existing sign corner grinding devices are inconvenient for adjusting and grinding signs of different sizes.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sign edge grinding device, including a main frame and a worktable. A control box is fixedly connected to one side of the main frame, and the worktable is fixedly connected to the top of the main frame. A reciprocating screw is rotatably connected to one end of the bottom inner side of the worktable. Both ends of the reciprocating screw are provided with slide rods. An auxiliary structure is threadedly connected to the top outer side of the reciprocating screw. The auxiliary structure includes a slide table, a slide groove, a pressing groove, an adjusting clamping frame, a fastening screw, a fixed clamping frame, a pressing plate, an adjusting screw, an adjusting nut, a first spring, a guide groove, a guide rod, a second spring, a reinforcing screw, a baffle plate, and rollers. The slide table is threadedly connected to the outer side of the reciprocating screw. A grinding pulley assembly is fixedly connected to the other end of the bottom inner side of the worktable. A collection structure is provided inside the bottom of the worktable.

[0007] In use, place the sign on top of the slide table, with the corner to be polished facing the polishing pulley assembly. The motor drives the reciprocating screw to move the slide table, which is threaded to it, back and forth. During the movement, the corner of the sign rubs against the activated polishing pulley assembly, thus polishing the corner of the sign.

[0008] Preferably, the top of the slide table has sliding grooves at both ends, a pressing groove at the middle of the top of the slide table, an adjusting clamping frame slidably connected to one side of the top of the slide table, a fastening screw threaded to the inner side of the top of the adjusting clamping frame, a fixing clamping frame fixedly connected to the other side of the top of the slide table, a pressing plate above the adjusting clamping frame, an adjusting screw fixedly connected to the middle of the other side of the top of the adjusting clamping frame, an adjusting nut threaded to the outer side of the adjusting screw, a first spring below the adjusting nut, a guide groove inside the pressing plate, guide rods fixedly connected to both ends of the other side of the top of the adjusting clamping frame, a second spring sleeved above the outer side of the guide rod, a reinforcing screw slidably connected to the inner side of the guide groove, a baffle fixedly connected to the bottom end of the reinforcing screw, and a roller rotatably connected to one side of the adjusting clamping frame.

[0009] Preferably, the slide table and the slide rod are connected by a thread, and the pressing plate and the guide rod are connected by a sliding structure, so as to facilitate the clamping of the sign.

[0010] Preferably, the adjusting screw and the adjusting nut are threaded together, and the baffle is perpendicular to the bottom of the fixed clamping frame, so as to prevent the sign from shifting backward during the grinding process.

[0011] Preferably, several rollers are rotatably connected to one side of the reinforcing screw, and the rollers are evenly distributed on one side of the reinforcing screw, so as to make it more convenient to adjust the grinding depth of the sign.

[0012] Preferably, the collection structure includes a baffle, a material drop trough, a material collection frame, a filter cartridge, an air pipe, and an air pump. The baffle is fixedly connected to the outside of the grinding pulley assembly. A material drop trough is provided inside the top of the workbench. A material collection frame is fixedly connected to the inside of the material drop trough. A filter cartridge is installed at the bottom of the material collection frame. An air pipe is installed on one side of the filter cartridge. An air pump is installed on one side of the air pipe. The traction suction generated by the air pump can adsorb and collect a large amount of debris.

[0013] Preferably, the material collection frame is connected to the interior of the filter cartridge, so that a strong traction suction force can be generated by the air pump.

[0014] Compared with the existing technology, the beneficial effects of this utility model are: the reciprocating movement of the slide table improves the efficiency of sign grinding, and the baffle can be pushed by the sliding reinforcing screw to adjust the grinding depth of the sign. At the same time, the debris generated during the grinding process falls into the filter cartridge through the material drop chute under the baffle of the baffle frame for collection.

[0015] 1. The sliding adjustable clamping frame allows the adjustable clamping frame and the fixed clamping frame to clamp the sign. Tightening the adjusting nut allows the pressing plate to press the sign, thereby avoiding excessive vibration during the polishing process.

[0016] Furthermore, the sliding reinforcing screw causes the baffle to abut against the end of the sign, thereby pushing the sign to adjust the grinding depth between the sign and the grinding pulley assembly;

[0017] 2. During the grinding operation, the debris is blocked by the baffle and falls into the chute. When the air pump is started, it can generate a strong traction force, which allows the debris to gradually fall into the collection frame and flow into the filter cartridge for collection.

An adjusting screw 608 is fixedly connected to the middle position of the other side of the top of the adjusting clamping frame 604. An adjusting nut 609 is threadedly connected to the outer side of the adjusting screw 608. A first spring 610 is provided below the adjusting nut 609. A guide groove 611 is provided inside the pressing plate 607. Guide rods 612 are fixedly connected to both ends of the other side of the top of the adjusting clamping frame 604. A second spring 613 is sleeved on the upper outer side of the guide rod 612. A reinforcing screw 614 is slidably connected inside the groove 611. A baffle 615 is fixedly connected to the bottom end of the reinforcing screw 614. A roller 616 is rotatably connected to one side of the adjusting clamp 604. The slide table 601 and the slide rod 5 are threadedly connected. The pressing plate 607 and the guide rod 612 are slidably connected.

Several rollers 616 are rotatably connected to one side of the reinforcing screw 614, and the rollers 616 are evenly distributed on one side of the reinforcing screw 614.

[0026] See attached document Figure 1 , Figure 3 and Figure 4When using this edge grinding equipment, the sign is placed inside the adjusting clamp 604 and the fixed clamp 606, and abuts against the top of the roller 616. Then, the adjusting clamp 604 is slid to clamp the sign with the adjusting clamp 604 and the fixed clamp 606. Then, the adjusting nut 609 is tightened to press the first spring 610 downward along the outer thread of the adjusting screw 608, so that the pressing plate 607 presses the sign to avoid excessive vibration during the grinding process. At the same time, the reinforcing screw 614 is slid to make the baffle 615 abut against the end of the sign, so that the sign can be pushed to adjust the grinding depth between the sign and the grinding pulley assembly 7. During grinding, the slide table 601 drives the sign to move back and forth under the drive of the slide rod 5, so that the edge of the sign gradually rubs against the grinding pulley assembly 7 and is ground.

The vacuum pump 806 is installed on one side of the air pipe 805. The internal parts of the material collection frame 803 and the filter cartridge 804 are connected.

[0028] See attached document Figure 1 , Figure 2 and Figure 5 When the corner grinding equipment grinds the corners of the sign, a large amount of debris is generated due to the friction between the grinding pulley assembly 7 and the corners of the sign. To avoid the large amount of debris being difficult to clean, a material drop trough 802 is opened inside the top of the workbench 3. During the grinding operation, the debris is blocked by the baffle 801 and falls into the material drop trough 802. During this process, the air pump 806 is activated to generate a strong traction force in the collection frame 803 and the filter cartridge 804 through the air pipe 805. This allows the debris to gradually fall into the collection frame 803 and flow into the filter cartridge 804 for collection under the action of traction force.
