Description

Technical Field

[0001] This utility model relates to the field of 3D printing consumable spools, specifically a 3D printing consumable spool feeding mechanism. Background Technology

[0002] 3D printing, also known as additive manufacturing technology, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional data. The raw materials for 3D printing are usually stored in spools, which means that a feeding structure is needed to feed the spools during 3D printing.

[0003] Patent application number "CN221476187U" discloses "a 3D printing consumable spool feeding mechanism, including a central cylinder and side plates located on both sides of the central cylinder. The 3D printing consumable spool feeding mechanism includes a limiting conveying track, a material drop port located at the end of the limiting conveying track, and a guide track located below the material drop port. The limiting conveying track includes two parallel limiting bars and a support bar located below the two limiting bars. The limiting bars cooperate with the side plates, and the support bar cooperates with the central cylinder." This patent has a simple structure and can realize continuous feeding of the spool.

[0004] However, in practical applications, the width of the conveyor track cannot be adjusted when using the above patent, which makes it easy for the width of the spool to be too large or too small when transporting spools of different specifications, resulting in poor feeding effect. In addition, the above patent lacks a buffer structure at the drop port, which makes the impact force of the spool large when it falls, and thus easily damages the spool. For example, when conveying wire reels with a larger width, the reels are prone to getting stuck on the conveyor track during transportation, resulting in a jam. When conveying wire reels with a smaller width, the reels are prone to deviating from the conveyor track, which leads to poor feeding efficiency of the device. Summary of the Invention

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a 3D printing consumable spool feeding mechanism to solve the technical problems of the above-mentioned patent, which cannot adjust the width of the conveyor track during use, making it easy for the spool width to be too large or too small when transporting spools of different specifications, resulting in poor feeding effect. In addition, the above-mentioned patent lacks a buffer structure at the drop port, which makes the impact force of the spool large when it falls, and thus easily damages the spool.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a 3D printing consumable spool feeding mechanism is designed, including a fixed frame, a conveyor belt is rotatably connected to the inner side of the fixed frame, anti-slip strips are fixedly connected to the outer side wall of the conveyor belt, and the anti-slip strips are evenly distributed, an adjustment mechanism is provided at the top of the fixed frame, a frame is fixedly connected to one side of the fixed frame, and a buffer mechanism is provided inside the frame.

[0007] In this solution, the conveyor belt can transport the wire reel, while the anti-slip strips provide an anti-slip effect, thereby improving the conveying efficiency of the conveyor belt.

[0008] Preferably, the adjustment mechanism includes a slide rail, a drive motor, a bidirectional lead screw, a slider, a roller frame, and a guide roller. The slide rail is fixedly connected to the top of the fixed frame. One end of the slide rail is fixedly connected to the drive motor. The end of the power output shaft of the drive motor is fixedly connected to the bidirectional lead screw. The end of the bidirectional lead screw passes through the slide rail and extends into the inner cavity of the slide rail.

[0009] In practical applications, a drive motor is used to rotate a bidirectional lead screw, which in turn moves a slider.

[0010] Preferably, sliders are screwed to both sides of the outer side wall of the bidirectional lead screw, and a roller frame is fixedly connected to the bottom of the sliders.

[0011] In practical applications, the distance between the guide rollers on both sides is adjusted by moving the roller frame through the slider.

[0012] Preferably, a guide roller is rotatably connected to the inner side of the roller frame, and the guide rollers are arranged sequentially from left to right.

[0013] In practical applications, guide rollers can be used to guide the reel, preventing it from shifting during transportation.

[0014] Preferably, a ramp is fixedly connected to one side of the bottom of the inner cavity of the frame, and a positioning platform is fixedly connected to the middle of the bottom of the inner cavity of the frame.

[0015] In practical applications, the inclined platform can guide the reel, preventing it from falling directly off the conveyor belt.

[0016] Preferably, an electric actuator is fixedly connected to one side of the frame, the output end of the electric actuator passes through the frame and extends into the inner cavity of the frame, and a push plate is fixedly connected to the output end of the electric actuator.

[0017] In practical applications, the push plate is moved by the electric push rod, so that the push plate pushes the spool on the positioning stage into the 3D printing device.

[0018] Preferably, the buffer mechanism includes a spring, a buffer plate, a sponge pad, and a damping rod. The spring is fixedly connected to one side of the inner cavity of the frame, and the other end of the spring is fixedly connected to the buffer plate. A sponge pad is fixedly connected to one side of the buffer plate, and a damping rod is fixedly connected to the middle of the other side of the buffer plate. The other end of the damping rod is fixedly connected to the middle of one side of the inner cavity of the frame.

[0019] In practical applications, the spool rolls towards the buffer plate under the guidance of the ramp platform, causing the spool to impact the sponge pad. The sponge pad provides initial cushioning to the spool, and then the spring and damping rod provide secondary cushioning to the spool, thus completely eliminating the impact force and allowing the spool to land safely and stably on the positioning platform.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, through the combination of an adjustment mechanism, drives a bidirectional lead screw to rotate during the conveying of the wire reel. This causes the bidirectional lead screw to move the sliders on both the front and rear sides, which in turn move the roller frame. This adjusts the position of the guide rollers inside the roller frame. When the distance between the front and rear guide rollers increases, the device can easily feed wire reels with a wider width. Conversely, when the distance between the front and rear guide rollers decreases, the device can easily feed wire reels with a narrower width. This allows the device to easily feed wire reels of different sizes, improving the device's performance.

[0021] 2. This utility model, through the combination of a buffer mechanism, allows the reel to fall onto a ramp platform when the conveyor belt transports it to the end. The ramp platform guides the reel, preventing it from falling directly onto the positioning platform. After being guided by the ramp platform, the reel impacts the buffer plate. At this point, a sponge pad provides initial cushioning, protecting the reel. A spring combined with a damping rod provides secondary cushioning, completely eliminating the impact force and allowing the reel to land safely and stably on the positioning platform. This ensures the device can reliably and safely catch the reel, preventing damage during transportation. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A 3D printing consumable spool feeding mechanism, see [link / reference] Figures 1 to 4 A fixed frame 100 is rotatably connected to the inner side of the fixed frame 100. Anti-slip strips 111 are fixedly connected to the outer side wall of the conveyor belt 110 and are evenly distributed. An adjustment mechanism is provided on the top of the fixed frame 100. A frame 200 is fixedly connected to one side of the fixed frame 100. A buffer mechanism is provided inside the frame 200. The conveyor belt 110 can transport the reel, and the anti-slip strips 111 provide an anti-slip effect, thereby improving the conveying effect of the conveyor belt 110. For details, see Figures 1 to 3 The adjustment mechanism includes a slide rail 120, a drive motor 130, a bidirectional lead screw 140, a slider 150, a roller frame 160, and a guide roller 170. The slide rail 120 is fixedly connected to the top of the fixed frame 100. One end of the slide rail 120 is fixedly connected to the drive motor 130. The end of the power output shaft of the drive motor 130 is fixedly connected to the bidirectional lead screw 140. The end of the bidirectional lead screw 140 passes through the slide rail 120 and extends into the inner cavity of the slide rail 120. Slider blocks 150 are screwed to both sides of the outer wall of the bidirectional lead screw 140. The bottom of the slider 150 is fixedly connected to the roller frame 160. The inner side of the roller frame 160 is rotatably connected to the guide roller 170, and the guide roller 170 is rotatably connected to the roller frame 160. Rollers 170 are arranged sequentially from left to right. A drive motor 130 drives a bidirectional lead screw 140 to rotate, which in turn moves the sliders 150 on both the front and rear sides. The sliders 150 then move the roller frame 160, adjusting the position of the guide rollers 170 inside the roller frame 160. When the distance between the front and rear guide rollers 170 increases, the device can easily feed wider reels of wire. Conversely, when the distance between the front and rear guide rollers 170 decreases, the device can easily feed narrower reels of wire. This allows the device to easily feed reels of different sizes, improving its performance.

[0025] Further, see Figure 1 , Figure 2 and Figure 4A ramp 210 is fixedly connected to one side of the bottom of the inner cavity of the frame 200. A positioning platform 220 is fixedly connected to the middle of the bottom of the inner cavity of the frame 200. An electric actuator 230 is fixedly connected to one side of the frame 200. The output end of the electric actuator 230 passes through the frame 200 and extends into the inner cavity of the frame 200. A push plate 240 is fixedly connected to the output end of the electric actuator 230. The buffer mechanism includes a spring 250, a buffer plate 260, a sponge pad 270, and a damping rod 280. The spring 250 is fixedly connected to one side of the inner cavity of the frame 200. The other end of the spring 250 is fixedly connected to the buffer plate 260. A sponge pad 270 is fixedly connected to one side of the buffer plate 260. A damping rod 280 is fixedly connected to the middle of the other side of the buffer plate 260. The other end of the damping rod 280 is fixedly connected to the middle of one side of the inner cavity of the frame 200. When the wire reel is transported to the end by the conveyor belt 110, the wire reel will fall onto the ramp platform 210, so that the ramp platform 210 can receive the wire reel and prevent the wire reel from falling directly onto the positioning platform 220. After being received and guided by the ramp platform 210, the wire reel will hit the buffer plate 260. At this time, the sponge pad 270 will provide initial buffering for the wire reel, thus providing initial protection for the wire reel. Then, the spring 250 and the damping rod 280 will provide secondary buffering for the wire reel, thus completely eliminating the impact force of the wire reel. This allows the wire reel to fall safely and stably onto the positioning platform 220, so that the device can stably and safely receive the wire reel and prevent the wire reel from being damaged during transportation.

[0026] In practical application, this solution works as follows: the drive motor 130 rotates the bidirectional lead screw 140, which in turn moves the sliders 150 on both sides. The sliders 150 then move the roller frame 160, adjusting the guide rollers 170 inside the roller frame 160 to the appropriate position. The conveyor belt 110 then transports the reel, causing it to fall onto the ramp 210. The ramp 210 guides the reel, causing it to roll toward the buffer plate 260. At this point, the sponge pad 270 provides initial cushioning, and the spring 250, in conjunction with the damping rod 280, provides secondary cushioning, completely eliminating the impact force on the reel. This allows the reel to land safely and stably on the positioning table 220, ensuring the device can securely and safely receive the reel and prevent damage during transport.

[0027] It should be noted that: the drive motor 130 refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is a common mechanical device. The electric actuator 230 is an electromechanical integrated actuator that converts electrical energy into linear reciprocating motion. Its core function is to replace traditional hydraulic, pneumatic, or manual mechanical structures to achieve precise and stable linear push-pull movements. It is widely used in fields such as automation control, smart homes, medical equipment, and industrial machinery.
