Description

Technical Field

[0001] This utility model belongs to the field of nursing product technology, specifically relating to an automatic replacement type moving knife feeding mechanism. Background Technology

[0002] Currently, in the assembly of the cutting head, the moving blades need to be fed into the assembly platform, and the assembly of various components is carried out based on the continuous operation of the robot. However, the moving blades are mainly stacked, that is, the moving blades are stacked on the carrier, and then automatically fill in the gaps in the movement of the carrier to complete the feeding of the moving blades.

[0003] However, due to the unevenness of the moving blades themselves, their stability becomes severely insufficient as the number of stacked blades increases (typically around 200 blades per stack). Therefore, the following technical defects exist in actual material feeding: During loading or unloading, blades may scatter due to shaking, tilting, or accidental tipping, severely impacting the normal supply of blades. During the replacement process, the blades are usually lifted by the movement of the vehicle to complete the equal height replacement. Once a single vehicle is lifted to the top, the vehicle needs to be lowered to the initial position. The replacement is then carried out by changing the vehicle and stacking the blades. Therefore, the operation is not only time-consuming and labor-intensive, but there is still a probability of overturning during the lifting process. The blades have an oil film on them, and once they are stacked, they are not easy to separate. Therefore, during the filling process, multiple blades will stick together. This not only increases the difficulty of feeding the blades one by one, but also increases the probability of the blades tipping over during the adsorption and picking process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved automatic replacement moving knife feeding mechanism.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic replacement type moving knife feeding mechanism includes a moving knife carrier and a power component. The moving knife carrier includes a carrier platform and a frame rod standing on the carrier platform. The frame rod can automatically match and pass through the internal space of the knife. A through hole is formed on the carrier platform with the frame rod as the reference. Multiple moving knives are stacked on the carrier platform with the frame rod as the reference. The power assembly includes a push rod assembly that extends from the top of the through hole and a power unit that drives the push rod assembly to move up and down for automatic positioning. The top surface of the push rod assembly and the carrier platform cooperate to form a support surface that flattens the moving blade. The moving blade feeding mechanism also includes an airflow assist component located at the top, wherein airflow is generated based on the airflow assist component to enter between the top blades to eliminate or reduce the adhesion force formed between the blade to be picked up and the blade to be replaced.

[0006] According to a specific embodiment and preferred aspect of the present invention, the through holes are located on opposite sides of the frame rod, and the top rod assembly includes multiple top rods that pass through the corresponding through holes and are arranged parallel to the frame rod, and a frame plate fixed to the bottom of the multiple top rods, wherein the power unit drives the frame plate to rise and fall to form automatic positioning.

[0007] In some specific embodiments, the top surface of the push rod is an uneven contact surface, and multiple contact surfaces and the bearing surface of the carrier platform combine to form a support surface, with multiple moving blades stacked in a centered, vertically aligned manner. Based on the leveling stacking, not only is the stability of the stack effectively increased, but the number of blades stacked at one time is also increased.

[0008] Preferably, the moving blade has a toothed portion and an assembly portion, wherein the moving blade is mounted on the bearing surface from the toothed portion and on the contact surface from the assembly portion to flatten the moving blade. Based on the bearing and contact support, the moving blades are stably stacked.

[0009] In some specific embodiments, there are two through holes, which are symmetrically distributed on opposite sides of the frame.

[0010] Preferably, each push rod slides relative to the inner wall of the through hole from its side. The motion guidance and constraint created by the through hole improves the stability of the lifting motion.

[0011] In some specific embodiments, the cross-section of the through hole is polygonal, and the top rod is prism-shaped with a corresponding number of sides. Generally, a combination of quadrilateral and square columns is used, which not only meets the guiding requirements but also forms lateral restraint.

[0012] According to another specific embodiment and preferred aspect of the invention, the support rod at least conforms to the inner space of the moving blade from opposite sides. This not only improves the stability of the blades stacked on the support frame, but also creates a movement barrier during top suction, which is more conducive to the separation of the two blades.

[0013] In addition, the airflow assist assembly includes a mounting base located in the replacement area, a nozzle mounted on the mounting base, an air pump, and air tubing, with the nozzle facing the blade to be picked up and the blade to be replaced. Based on airflow purging, the adhesion between the blades is minimized as much as possible to reduce the error rate of picking up individual blades.

[0014] Preferably, the moving blades form a U-shaped notch on the side away from the comb teeth, and the mounting base is located within the U-shaped notch. The airflow area generated by the nozzle covers the entire mounting base corresponding to the multiple moving blades. This coverage of the airflow area facilitates the relative separation of the blades, providing better assistance for single-blade material handling.

[0015] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: In existing moving blade feeding processes, the unevenness of the blades themselves leads to insufficient stability as the number of stacked blades increases (typically around 200 blades per stack). Consequently, blades may tilt or accidentally tip over and scatter during transfer or relocation, severely impacting normal blade supply. Furthermore, blade replacement typically involves lifting the blades using a carrier. Once a single carrier reaches its top, it must be lowered back to its initial position, requiring carrier replacement and blade stacking for continuous replacement. This process is time-consuming and labor-intensive, and tipping remains a possibility during lifting. Additionally, the presence of an oil film on the blades makes them difficult to separate once stacked, leading to multiple blades adhering during replacement. This not only increases the difficulty of feeding blades individually but also increases the likelihood of tipping during material removal. This invention addresses these shortcomings by ingeniously designing an automatic replacement moving blade feeding mechanism. To address the shortcomings and defects of the existing technology, this moving blade feeding mechanism first utilizes the internal positioning formed by the support rod and the carrier platform. Combined with the top surface of the top rod assembly and the carrier platform, it forms a support surface to flatten the moving blades. Multiple blades are stacked relatively flat on the carrier platform, using the support rod as a reference. Secondly, the power for automatic replacement is generated by the lifting and lowering movement of the top rod through the through hole in the carrier platform. Simultaneously, airflow enters between the top blades to eliminate or reduce the adhesion between the blades to be picked up and the blades to be replaced. Thus, without moving the carrier platform, the blades are automatically and sequentially raised and replaced. Therefore, this invention, based on flattening and internal positioning, not only achieves stable stacking of multiple blades but also reduces the probability of tilting or accidental overturning and scattering during transfer or relocation. Furthermore, based on the stationary carrier platform and the power for automatic replacement via the lifting and lowering movement of the top rod through the through hole, along with airflow to eliminate or reduce the adhesion between the blades to be picked up and the blades to be replaced, it achieves efficient and high-quality automatic replacement of individual blades.

[0023] like Figures 1 to 5 As shown, the automatic replacement type moving knife feeding mechanism of this embodiment includes a moving knife carrier 1, a power component 2, and an airflow auxiliary component 3.

[0024] Specifically, the moving blade carrier 1 includes a carrier platform 10 and a support rod 11 erected on the carrier platform 10. The support rod 11 can automatically match and pass through the internal space q of the moving blade M. A through hole 100 is formed on the carrier platform 10 with the support rod 11 as the reference. Multiple moving blades M are stacked on the carrier platform 10 with the support rod 11 as the reference. The support rod 11 is at least in contact with the internal space q of the moving blades from opposite sides. This not only improves the stability of the blades stacked on the carrier, but also creates a movement obstacle when the blades are picked up from the top, which is more conducive to the separation of two blades.

[0025] The power assembly 2 includes a push rod assembly 20 extending from the top of the through hole 100 and a power unit 21 that drives the push rod assembly 20 to move up and down for automatic positioning. The top surface of the push rod assembly 20 cooperates with the carrier platform 10 to form a support surface for leveling the moving blade. The power unit 21 guides the up and down movement based on a slide rail or guide shoe and uses linear drive for lifting and adjusting. The linear drive can use conventional cylinders, hydraulic cylinders, or electric cylinders, or conventional structures such as transmission screws.

[0026] The airflow assist component 3 includes a mounting base 30 located in the replacement area, a nozzle 31 mounted on the mounting base 30, an air pump, and an air pipe, wherein the nozzle 31 is directly facing the blade to be picked up and the blade to be replaced. Based on airflow purging, the adhesion between the blades is minimized as much as possible to reduce the error rate of picking up a single blade.

[0027] In some specific embodiments, the top surface of the carrier platform 10 is a horizontal plane, the support rod 11 is located in the middle of the horizontal plane, and there are two through holes 100, which are symmetrically arranged on opposite sides of the support rod 11. The top rod assembly 20 includes multiple top rods 200 that pass through the corresponding through holes 100 and are arranged parallel to the support rod 11, and a frame plate 201 fixed to the bottom of the multiple top rods 200, wherein the power unit drives the frame plate 201 to rise and fall to form automatic positioning. The top surface of the top rod 200 is an uneven contact surface, and the multiple contact surfaces and the bearing surface of the carrier platform 10 combine to form a support surface, and the multiple moving blades M are stacked with their centers aligned vertically. Based on the flattened stacking, not only is the stability of the stacking effectively increased, but the number of blades stacked at one time is also increased. At the same time, each top rod 200 slides relative to the inner wall of the through hole 100 from the side. Based on the motion guidance and restriction formed by the through holes, the stability of the lifting motion is improved. In this example, the cross-section of the through hole 100 is polygonal, and the top rod 200 is a prism with a corresponding number of sides. Generally, a combination of quadrilateral and square columns is used, which not only meets the guiding requirements but also provides lateral restraint.

[0028] In this example, the moving blade M has a toothed portion m1 and an assembly portion m2. The moving blade M is mounted on the bearing surface from the toothed portion m1 and on the contact surface from the assembly portion m2 to flatten it. Based on the bearing and contact support, the moving blades are stably stacked. Simultaneously, the moving blade M forms a U-shaped notch away from the comb tooth side (equivalent to the assembly portion m2), and the mounting base 30 is located within this U-shaped notch. The airflow area formed by the nozzle 31 covers the entire mounting base 30 and the multiple moving blades M corresponding to it. This coverage of the airflow area facilitates the relative separation of the blades, providing better assistance for single-blade material handling.

[0029] In summary, by employing this moving blade feeding mechanism, the internal positioning formed by the frame rod and the carrier platform, combined with the cooperation of the top surface of the top rod assembly and the carrier platform, forms a support surface to flatten the moving blade. Multiple blades are stacked relatively flat on the carrier platform, with the frame rod as the reference. Secondly, the lifting and lowering motion of the top rod, passing through the through hole in the carrier platform, provides the power for automatic positioning. Simultaneously, airflow enters between the top blades to eliminate or reduce the adhesion between the blades to be picked up and the blades to be positioned. Thus, without moving the carrier platform, the blades are automatically positioned one by one as they rise. Therefore, this invention, based on flattening and internal positioning, can not only achieve multiple... The blades are stacked smoothly, with a low probability of tilting or accidental tipping and scattering during transfer or relocation. Secondly, based on a stationary carrier platform, the automatic positioning is achieved through a self-penetrating hole-driven lifting rod, while airflow purging eliminates or reduces the adhesion between the blades to be picked up and those to be replaced, resulting in efficient and high-quality automatic blade replacement. Thirdly, the flattened stacking not only effectively increases stacking stability but also increases the number of blades stacked at once, while load-bearing and contact point support ensure smooth stacking of moving blades. Fourthly, the motion guidance and constraint provided by the through-hole enhance the stability of the lifting motion. The cross-section of the through hole is polygonal, and the top rod is a prism with a corresponding number of sides. Generally, a combination of quadrilateral and square columns is used, which not only meets the guiding requirements but also forms lateral restraint. Fifthly, the frame rod at least adheres to the inner space of the moving blade from both opposite sides, which not only improves the stability of the blades stacked on the carrier but also creates a movement obstacle when picking up from the top, which is more conducive to the separation of the two blades. Sixthly, based on airflow purging, the adhesion between the blades is minimized as much as possible to reduce the error rate of single blade picking. At the same time, the coverage of the airflow purging area is more conducive to the relative separation of the blades, providing better assistance for single blade picking.

However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
