Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically a cardboard box nailing machine with a protective structure. Background Technology

[0002] With increasing market competition, users are demanding higher production efficiency from carton stapling machines. They want these machines to complete stapling tasks quickly and accurately, reducing production cycles and improving the company's economic benefits.

[0003] A search revealed a utility model patent with Chinese patent publication number CN213167116U, which discloses a carton stapling machine with a uniform speed pushing structure. The carton stapling machine includes a base, a support rod, a first crossbeam, a slide groove, a pushing component, a second crossbeam, and a stapling component. The support rod is installed on the upper end of the base, and the first crossbeam is installed on the side of the support rod. The upper end of the first crossbeam has a slide groove, and a pair of fixed seats are installed on the bottom surface of the inner cavity of the first crossbeam. A cylinder is installed on the upper end of the fixed seats.

[0004] During the nailing process, nails may fly off for various reasons, such as poor nail quality or machine malfunction. These flying nails or other small parts may cause injury to the operator's eyes, face, or other parts, seriously affecting the operator's personal safety. Utility Model Content

[0005] The purpose of this invention is to provide a carton nailing machine with a protective structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carton nailing machine with a protective structure, comprising a support frame, a horizontally arranged extension frame fixedly connected to the top outer wall of the support frame, a protective assembly installed on the outside of the extension frame, the protective assembly comprising two protective covers rotatably connected to the outer walls of both sides of the extension frame via hinges, and both protective covers being located at the top of the support frame, a vertically arranged limiting frame fixedly connected to one end of the extension frame, a vertical lead screw rotatably connected inside the limiting frame, a top rod threaded onto the outside of the lead screw rotatable, the top rod contacting the top inner walls of the two protective covers, two vertically arranged guide rods fixedly connected inside the limiting frame, the top rod slidably sleeved on the outside of the two guide rods, a motor fixedly installed on the top outer wall of the limiting frame, the output end of the motor being coaxially fixed with one top end of the lead screw rotatable.

[0007] The device can intercept nails that fly outwards, improving safety and allowing the nail gun to be exposed to the outside environment when needed for maintenance. Two protective covers on both sides of the nail gun intercept the flying nails, which then fall down along the covers, preventing them from continuing to fly outwards and injuring workers. If maintenance is required, the motor drives the lead screw to rotate, which in turn drives the top rod to move upwards along the guide rod. The top rod then lifts the movable end of the protective cover and flips it upwards by nearly 90 degrees, exposing the nail gun to the outside environment.

[0008] As a further preferred embodiment of this technical solution, a nailing assembly is installed at the bottom of the extension frame. The nailing assembly includes a connecting frame that slides inside the extension frame. Two support covers are fixedly connected to the outside of the bottom of the connecting frame. Several equally spaced conveying rollers are rotatably connected inside each of the two support covers. An installation cover is installed outside each of the two support covers, and a conveying assembly adapted to the several conveying rollers is installed inside the installation cover. Several receiving rollers are rotatably connected inside the bracket, and the several receiving rollers correspond one-to-one with the several conveying rollers.

[0009] As a further preferred embodiment of this technical solution, a nail gun is installed on the inner wall of the top of the extension frame, the nail gun is located between the two support covers, and a vertically arranged lead screw is rotatably connected to the outer wall of the top of the extension frame, the lead screw being threaded into the inside of the connecting frame.

[0010] Adjust the position of the support cover according to the thickness of the carton to ensure that the carton connection can be clamped while the paper is not over-compressed and damaged. Drive the screw two to rotate through the wheel. The connecting frame inserted inside the extension frame cannot rotate but can only move up and down. The rotating screw two can drive the connecting frame to move in the vertical direction. The two support covers at the bottom of the connecting frame will also be driven to move synchronously. At this time, simply insert the carton with the two ends overlapping into the outside of the bracket to complete the connection. This can avoid insufficient restriction at the carton connection to affect the processing quality.

[0011] As a further preferred embodiment of this technical solution, a storage cabinet is fixedly connected to one inner wall of the bracket, and several storage boxes are slidably inserted into the storage cabinet.

[0012] As a further preferred embodiment of this technical solution, each of the two protective covers is fixedly connected to two horizontally arranged extension rods, and each of the four extension rods has a curtain fixed to its bottom outer wall.

[0013] As a further preferred embodiment of this technical solution, both the conveying roller and the receiving roller are rubber-coated rollers.

[0014] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread of the lead screw is less than the equivalent friction angle.

[0015] This utility model provides a carton stapler with a protective structure, which has the following beneficial effects:

[0016] (1) By setting up protective components, this utility model can intercept nails that are splashed to the outside, which is beneficial to improving the safety of the device. It can also expose the nail gun to the external environment when needed, which is convenient for maintenance work. The two protective covers on both sides of the nail gun can intercept the splashed nails, which then fall down along the protective covers, preventing them from continuing to splash outward and injuring the workers. If the nail gun needs to be maintained, the motor drives the lead screw to rotate, and the lead screw can drive the top rod to move upward along the guide rod. The top rod can lift the movable end of the protective cover and flip it upward to nearly ninety degrees, and then the nail gun will be exposed to the outside.

[0017] (2) By setting a nailing component, the position of the support cover is adjusted according to the thickness of the carton, ensuring that the carton connection can be clamped while the paper is not compressed too much and damaged. The screw two is driven by the wheel to start rotating. The connecting frame inserted inside the extension frame cannot rotate but can only move up and down. The rotating screw two can drive the connecting frame to move in the vertical direction. The two support covers at the bottom of the connecting frame will also be driven to move synchronously. At this time, the connection can be completed by inserting the carton with the two ends overlapping into the outside of the bracket. It can also avoid the carton connection not being restricted enough and affecting the processing quality. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: such as Figure 3 and Figure 4 As shown, in this embodiment, a carton nailing machine with a protective structure includes a support 1. A horizontally arranged extension frame 2 is fixedly connected to the top outer wall of the support 1. A protective component 5 is installed on the outside of the extension frame 2. The protective component 5 includes two protective covers 503 that are rotatably connected to the outer walls of both sides of the extension frame 2 by hinges, and both protective covers 503 are located at the top of the support 1. A vertically arranged limiting frame 501 is fixedly connected to one end of the extension frame 2. A vertical lead screw 504 is rotatably connected inside the limiting frame 501. A top rod 502 is threaded on the outside of the lead screw 504. The top rod 502 contacts the top inner wall of the two protective covers 503. Two vertically arranged guide rods 505 are fixedly connected inside the limiting frame 501. The top rod 502 is slidably sleeved on the outside of the two guide rods 505. A motor 506 is fixedly installed on the top outer wall of the limiting frame 501. The output end of the motor 506 is coaxially fixed with one end of the top of the lead screw 504.

[0025] The two protective covers 503 on both sides of the nail gun 604 can intercept the flying nails, which then fall down along the protective covers 503, preventing them from continuing to fly outward and injuring the workers. If the nail gun 604 needs to be repaired, the control motor 506 drives the lead screw 504 to rotate. The lead screw 504 then drives the top rod 502 to move upward along the guide rod 505. The top rod 502 can lift the movable end of the protective cover 503 and flip it upward by nearly ninety degrees. Then the nail gun 604 will be exposed to the outside world, which facilitates the work.

[0026] like Figure 1 and Figure 2 As shown, a nailing assembly 6 is installed at the bottom of the extension frame 2. The nailing assembly 6 includes a connecting frame 601 that is slidably inserted inside the extension frame 2. Two support covers 602 are fixedly connected to the bottom of the connecting frame 601. Several conveying rollers 603 that are equidistantly distributed are rotatably connected inside the two support covers 602. An installation cover is installed outside the two support covers 602, and a conveying assembly adapted to several conveying rollers 603 is installed inside the installation cover. Several receiving rollers 605 are rotatably connected inside the bracket 1. The several receiving rollers 605 correspond one-to-one with the several conveying rollers 603.

[0027] A nail gun 604 (U-shaped nail gun, preferably UT-2380J) is installed on the inner wall of the top of the extension frame 2. The nail gun 604 is located in the middle of the two support covers 602. A vertically set screw rod 606 is rotatably connected to the outer wall of the top of the extension frame 2. The screw rod 606 is threaded inside the connecting frame 601.

[0028] The position of the support cover 602 is adjusted according to the thickness of the carton to ensure that the carton connection can be clamped while the paper is not over-compressed and damaged. The screw 606 is driven to rotate by the wheel. The connecting frame 601 inserted inside the extension frame 2 cannot rotate but can only move up and down. The rotating screw 606 can drive the connecting frame 601 to move vertically. The two support covers 602 at the bottom of the connecting frame 601 will also be driven to move synchronously. At this time, the carton with the two ends overlapping can be inserted into the outside of the bracket 1 to complete the connection. This can avoid the carton connection not being restricted enough and affecting the processing quality. The carton first approaches the outer support cover 602. The multiple conveying rollers 603 inside are driven to rotate by the transmission structure. With the cooperation of the receiving roller 605, they will move towards the nail gun 604. Then, the nail gun 604 is controlled to nail the carton connection. With the cooperation of the other support cover 602, the entire carton can be nailed. Finally, the carton is conveyed out to complete the processing.

[0029] like Figure 1 and Figure 2 As shown, a storage cabinet 3 is fixedly connected to the inner wall of one side of the bracket 1. Several storage boxes 4 are slidably inserted inside the storage cabinet 3, so that the device has a storage function and facilitates the placement of parts, boxes and tools.

[0030] like Figure 3 As shown, each of the two protective covers 503 has two horizontally arranged extension rods 507 fixedly connected to its exterior. Each of the four extension rods 507 has a curtain 508 fixed to its bottom outer wall, which can improve the protective effect of the protective cover 503 without affecting its upward flipping.

[0031] like Figure 2 As shown, both the conveyor roller 603 and the receiving roller 605 are rubber-coated rollers, which helps to improve their friction with the carton and prevent slippage during the conveying process.

[0032] like Figure 1 and Figure 2 As shown, the thread helix angle of the external thread of the lead screw 606 is less than the equivalent friction angle, giving it a self-locking effect.

[0033] This utility model provides a carton stapler with a protective structure, the specific working principle of which is as follows:

[0034] When the device is working, the position of the support cover 602 is adjusted according to the thickness of the carton to ensure that the carton connection can be clamped while the paper is not over-compressed and damaged. The screw 606 is driven to rotate by the wheel. The connecting frame 601 inserted inside the extension frame 2 cannot rotate but can only move up and down. The rotating screw 606 can drive the connecting frame 601 to move in the vertical direction. The two support covers 602 at the bottom of the connecting frame 601 will also be driven to move synchronously. At this time, the carton with the two ends overlapping can be inserted into the outside of the bracket 1 to complete the connection. This can avoid the carton connection not being restricted enough and affecting the processing quality. The carton first approaches the outer support cover 602. The multiple conveying rollers 603 inside are driven to rotate by the transmission structure. With the cooperation of the receiving roller 605, they will move towards the nail gun 604. Then, the nail gun 604 is controlled to nail the carton connection. With the cooperation of the other support cover 602, the entire carton can be nailed. Finally, the carton is conveyed out to complete the processing. The two protective covers 503 on both sides of the nail gun 604 can intercept the flying nails, which then fall down along the protective covers 503, preventing them from continuing to fly outward and injuring the workers. If the nail gun 604 needs to be repaired, the control motor 506 drives the lead screw 504 to rotate. The lead screw 504 then drives the top rod 502 to move upward along the guide rod 505. The top rod 502 can lift the movable end of the protective cover 503 and flip it upward by nearly ninety degrees. Then the nail gun 604 will be exposed to the outside world, which facilitates the work.
