Description

Technical Field

[0001] This invention relates to the field of automated packaging, and more particularly to an automated strapping device using door-shaped nails. Background Technology

[0002] Door-shaped nails consist of round pieces and U-shaped nails. The U-shaped nails have two pointed ends on the side away from the round pieces. The conventional packaging method is to first stack multiple door-shaped nails together, then tie two elastic bands to the front and back sides of the stacked door-shaped nails respectively, and then put the bundled door-shaped nails into a plastic bag. At this time, since the pointed ends of all the door-shaped nails are facing the same side, the pointed ends of the door-shaped nails are easy to puncture the plastic bag when subjected to violent bumps and shaking during transportation, causing significant damage to the plastic packaging. Users are also likely to be injured by the exposed pointed ends of the door-shaped nails when picking up the plastic bag, posing a significant safety hazard. Summary of the Invention

[0003] To overcome the drawback that the sharp ends of the gate nails can easily puncture the plastic packaging after stacking and packaging, thus posing a safety hazard of injuring users, this invention provides an automated gate nail strapping device.

[0004] The technical implementation scheme of the present invention is as follows: an automated door-type nail binding device, comprising a mounting frame, a stacking frame, a transverse limiting plate, a support plate, an electric telescopic rod, a longitudinal limiting plate, a push plate, an electric push rod, a hanging mechanism, and an insert plate; the stacking frame is fixedly connected to the mounting frame; two transverse limiting plates are fixedly connected inside the stacking frame; a support plate is slidably connected to the bottom of the transverse limiting plate; electric telescopic rods that drive the two support plates to move laterally in the left and right directions are respectively installed on the left and right sides of the stacking frame; two longitudinal limiting plates are inserted between the two support plates; two push plates are slidably connected to the stacking frame; electric push rods that drive the two push plates to move longitudinally in the front and rear directions are respectively installed on the front and rear sides of the stacking frame; a hanging mechanism for hanging binding rubber bands is connected to the push plate; an insert plate is fixedly connected to the push plate; and slots corresponding to the insert plates are opened on the longitudinal limiting plate.

[0005] More preferably, the upper ends of the two longitudinal limiting plates are inclined towards each other.

[0006] More preferably, the mounting mechanism consists of two electric lifting plates and four hanging rods; an electric lifting plate is slidably connected to the upper and lower sides of the push plate; and hanging rods are fixedly connected to the electric lifting plates.

[0007] More preferably, the hanging rod has grooves.

[0012] More preferably, the opposing sides of the two guide ramps are designed as a guide structure that converges towards the center.

[0013] More preferably, an electronic counter is installed on the guide ramp.

[0014] The beneficial effects of this invention are as follows: This invention provides an automated door-shaped nail strapping device that alternately stacks door-shaped nails with their circular pieces facing opposite directions. A longitudinal limiting plate and a pusher plate are used to neatly align the stacked door-shaped nails, concealing the tips of adjacent door-shaped nails between adjacent circular pieces. This reduces the risk of the nail tips puncturing users and packaging bags. A hanging mechanism is also included to replace manual labor in attaching strapping elastic bands to the door-shaped nails, preventing workers from being injured by the nail tips during manual strapping. Furthermore, a plastic sleeve is injection-molded into the tips of the top and bottom door-shaped nails using a sleeve mold, isolating and protecting the tips of all door-shaped nails. Additionally, two alternating electric conveyor machines replace manual stacking of the door-shaped nails, overcoming the technical defect that the tips of the stacked door-shaped nails easily puncture the plastic packaging, posing a safety hazard to users.

Detailed Implementation

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: An automated door-type nail binding device, such as... Figures 1-6 As shown, the system includes a mounting frame 1, a collection tray 11, a stacking frame 2, a lateral limiting plate 21, a support plate 22, an electric telescopic rod 23, a longitudinal limiting plate 24, a push plate 31, an electric push rod 32, a hanging mechanism, and an insert plate 35. The stacking frame 2 is fixedly connected to the mounting frame 1. A collection tray 11 aligned with the bottom of the stacking frame 2 is fixedly connected to the mounting frame 1. Two lateral limiting plates 21 are fixedly connected inside the stacking frame 2. A support plate 22 is slidably connected to the bottom of each of the two lateral limiting plates 21. Two electric telescopic rods 23 are installed on the left and right sides of the stacking frame 2. The telescopic end of each electric telescopic rod 23 is fixedly connected to the support plate 22 on the same side. Between the two support plates 22... Two longitudinal limiting plates 24 are inserted and connected; two push plates 31 are slidably connected to the stacking frame 2; two electric push rods 32 are installed on the front and rear sides of the stacking frame 2; the telescopic end of each electric push rod 32 is fixed to the push plate 31 on the same side; a hanging mechanism is connected to each of the two push plates 31; an insert plate 35 is fixed to each of the two push plates 31; a slot 2401 corresponding to the insert plate 35 is opened on each of the two longitudinal limiting plates 24; the upper ends of the two longitudinal limiting plates 24 are inclined towards each other, and the circular piece 61 of the fallen door nail body 6 moves away from the other longitudinal limiting plate 24 along the inclined guide structure of the longitudinal limiting plate 24 on the same side.

[0019] like Figure 6As shown, the hanging mechanism consists of two electric lifting plates 33 and four hanging rods 34; an electric lifting plate 33 is slidably connected to the upper and lower sides of the push plate 31; two hanging rods 34 are fixedly connected to each of the two electric lifting plates 33; each hanging rod 34 has a groove 3401 for hanging and binding rubber bands.

[0020] In this embodiment, during use, the worker stacks multiple door-shaped nail bodies 6 with the circular pieces 61 facing different directions on the two trays 22 in the stacking frame 2, such as... Figure 8 As shown, the portal nail body 6 is clamped between two horizontal limiting plates 21 on the left and right. Then, the workers hang two binding rubber bands on the hanging rods 34 of the front and rear hanging mechanisms. The binding rubber bands are hung between the grooves 3401 of the four hanging rods 34 of the same push plate 31. Then, the upper and lower electric lifting plates 33 drive the hanging rods 34 connected to them to move away from each other. The binding rubber bands are stretched up and down by the hanging rods 34. Then, the electric push rod 32 pulls the push plate 31, which drives the binding rubber bands stretched by the hanging rods 34 to move towards the portal nail body 6 stacked in the stacking frame 2. The push plate 31 pushes the round piece 61 of the portal nail body 6 to move towards the longitudinal limiting plate 24 on the same side, so that the round piece 61 of the portal nail body 6 is squeezed between the push plate 31 and the longitudinal limiting plate 24, so that the adjacent pieces are squeezed together. When the circular pieces 61 are aligned, the tip of the U-shaped nail 62 located in the middle layer of the door-shaped nail body 6 is hidden between the two adjacent circular pieces 61, so that the U-shaped nail 62 of the middle layer of the door-shaped nail body 6 will not puncture the user or the packaging bag. At the same time, the elastic band that has been stretched out is put on one side of the stacked door-shaped nail body 6. The two electric lifting plates 33 then drive the hanging rod 34 to move towards each other, and the hanging rod 34 loosens the elastic band. The elastic band loses the vertical support of the hanging rod 34. Then the electric push rod 32 pushes the push plate 31 to move the hanging rod 34 in the opposite direction and reset it, so that the hanging rod 34 leaves the elastic band. At this time, the elastic band loses the horizontal support of the hanging rod 34 and is completely tightened on one side of the stacked door-shaped nail body 6, completing the automatic putting of the elastic band on the stacked door-shaped nail body 6.

[0021] Then, the electric push rod 32 pulls the push plate 31 again, causing the insert plate 35 to move towards the stacking frame 2 until the insert plate 35 is inserted into the slot 2401 of the longitudinal limiting plate 24 on the same side. At this time, the longitudinal limiting plate 24 is fixed on the insert plate 35. Then, the electric telescopic rods 23 on the left and right sides pull the two support plates 22 away from each other, so that the support plates 22 leave the bottom of the stacked gate nail body 6, and the gate nail body 6 that has completed the binding rubber band sleeve work can fall down from the stacking frame 2 into the collection tray 11.

[0022] Example 2, based on Example 1 above, as follows: Figures 1-7As shown, in this embodiment, a diversion pipe 41 is fixedly connected to the upper side of the front push plate 31, and the diversion pipe 41 is externally connected to a small injection molding device; a diversion pipe 41 is fixedly connected to the lower side of the rear push plate 31; each of the two diversion pipes 41 is connected to two branch pipes 42; the outlet end of each of the four branch pipes 42 is connected to a sleeve mold 43; the two diversion pipes 41 and the four branch pipes 42 are all heat-insulating pipes, used to keep the high-temperature molten injection molding raw material flowing inside warm; each of the four sleeve molds 43 has an air inlet channel 4301, and the air inlet channel 4301 is externally connected to a cooling airflow conveying device; each of the four sleeve molds 43 has a plurality of jet micro-holes 4302 connected to the corresponding air inlet channel 4301 on its inner wall.

[0023] In this embodiment, after the workers alternately stack a specified number of door-shaped nail bodies 6 in the stacking frame 2, the tips of the U-shaped nails 62 in the middle layer of door-shaped nail bodies 6 are hidden between two adjacent circular plates 61, preventing the U-shaped nails 62 in the middle layer of door-shaped nail bodies 6 from puncturing users or packaging bags. However, the U-shaped nails 62 in the top and bottom layers of door-shaped nail bodies 6 are not completely covered, and there is still a safety hazard of puncturing users and packaging bags. Therefore, the electric push rod 32 pushes the push plate 31 closer to the door-shaped nail bodies in the stacking frame 2. During the process of forming body 6, the push plate 31 moves the diversion pipe 41, branch pipe 42, and sleeve mold 43, so that the two front sleeve molds 43 are respectively fitted onto the outside of the two tips of the U-shaped nail 62 of the top-layer gate nail body 6, and the two rear sleeve molds 43 are respectively fitted onto the outside of the two tips of the U-shaped nail 62 of the bottom-layer gate nail body 6. Then, the external small injection molding equipment sequentially injects high-temperature molten injection molding material into each sleeve mold 43 through the diversion pipe 41 and branch pipe 42, so that the injection molding material wraps around the tip of the corresponding U-shaped nail 62. After the small injection molding equipment stops injection, the external cooling airflow delivery device delivers cooling airflow to the air inlet channel 4301 of the sleeve mold 43. The cooling airflow is ejected from the jet micro-holes 4302 and contacts the injection material inside the sleeve mold 43, causing the injection material inside the sleeve mold 43 to cool and shrink rapidly, wrapping around the tip of the corresponding U-shaped nail 62 and forming a plastic sleeve. At the same time, the continuously blown cooling airflow will quickly form an isolation film between the inner wall of the sleeve mold 43 and the injection material, accelerating the removal of the injection material from the inner wall of the sleeve mold 43. The molding speed allows for the installation of a plastic sleeve on the tip of the U-shaped nail 62 of both the top and bottom gate nail bodies 6. This effectively prevents the tips of the U-shaped nails 62 from puncturing users or damaging packaging bags. Compared to the traditional method of directly covering the tips of the U-shaped nails 62 with plastic protective caps, this embodiment uses a method of cooling and shrinking injection molding material to wrap the tips of the U-shaped nails 62. This makes the plastic sleeve more securely and stably fitted onto the tips of the U-shaped nails 62, preventing the plastic sleeve from falling off during handling.

[0024] Example 3, based on Example 1 above, as follows: Figures 1-6 As shown, in this embodiment, an electric conveyor 51 is installed on the left side of the mounting frame 1; an electric conveyor 51 is also installed on the right side of the mounting frame 1; two guide ramps 52 are installed on the mounting frame 1, and the guide ramps 52 are inclined downward toward the stacking frame 2; the upper end of the left guide ramp 52 is connected to the right end of the left electric conveyor 51; the upper end of the right guide ramp 52 is connected to the left end of the right electric conveyor 51; the opposing sides of the two guide ramps 52 are provided with a guide structure that converges toward the middle; an electronic counter 53 is installed on the lower side of each of the two guide ramps 52.

[0025] In this embodiment, two electric conveyor machines 51 are used to replace manual labor for the alternating feeding of the portal nail bodies 6. The electric conveyor machine 51 on the left conveys the disc 61 to the right, facing the portal nail body 6 in front, while the electric conveyor machine 51 on the right conveys the disc 61 to the left, facing the portal nail body 6 in rear. First, the electric conveyor machine 51 on the left conveys one portal nail body 6 to the right. This portal nail body 6 slides down along the left guide ramp 52 between the two transverse limiting plates 21 in the stacking frame 2. At this time, the electronic counter 53 on the left guide ramp 52 automatically increments by one. Then, the electric conveyor machine 51 on the right conveys one portal nail body 6 to the left. This portal nail body 6 slides down along the right guide ramp. 52 slides down between the two transverse limiting plates 21 in the stacking frame 2. At this time, the electronic counter 53 on the right guide ramp 52 automatically increments by one count. Then, the above steps are repeated so that the two electric conveyor machines 51 alternately convey the two different orientations of the gate nail body 6 to the stacking frame 2 for stacking until the sum of the counts of the two electronic counters 53 reaches the required stacking quantity. This replaces manual labor to automatically complete the stacking of the gate nail body 6 in the stacking frame 2. At the same time, the staff only needs to hang the two binding rubber bands in the grooves 3401 of the front and rear hanging rods 34 respectively. Alternatively, an external robotic arm mechanism can be used to replace manual labor to hang the binding rubber bands in the grooves 3401 of the front and rear hanging rods 34.

[0026] This embodiment enables the automatic stacking of the portal nail body 6 and the feeding of the binding rubber bands to be carried out simultaneously, which shortens the preparation time for the binding of the portal nail body 6 and improves the binding efficiency of the portal nail body 6.
