Description

Technical Field

[0001] This utility model belongs to the field of blade printing technology, specifically relating to a transfer structure for blade printing. Background Technology

[0002] Pruning machines are suitable for professional pruning in landscaping applications such as tea plantation trimming, park gardens, and roadside hedges. The machines are equipped with blades for trimming vegetation. After production, the pruning machine blades need to have their logo printed on their surface using a printing press (in the pruning machine blade production process, logo printing is a key step for product traceability, brand identification, and safety compliance). However, in current printing processes, the loading and unloading of the blades are done manually by the operator.

[0003] Actual measurements showed that the manual feeding speed was only 10-15 pieces / minute, far lower than the production cycle of 30-50 pieces / minute for high-speed printing machines, creating a bottleneck in production capacity. At the same time, manual feeding and unloading by operators increased their labor intensity and required additional labor costs. These problems seriously restricted the efficiency improvement of automated blade printing production lines. Utility Model Content

[0004] This invention provides a transfer structure for blade printing, which solves the problems of low efficiency and high cost in the existing printing process, where the loading and unloading of blades are all done manually by the operator.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a transfer structure for blade printing, comprising:

[0006] Support box;

[0007] A transition assembly, the transition assembly comprising a carrier plate rotatably mounted on top of the support box and a carrier plate circumferentially disposed on top of the carrier plate;

[0008] A feeding assembly, mounted on one side of the transition assembly, is used to grip the blade and place it on the carrier plate;

[0009] A feeding assembly, mounted on the other side of the transition assembly, is used to grip and transfer the printed blades on the carrier plate.

[0010] Optimally, the transition assembly further includes a first motor fixed to the top of the support box and a first turntable connected to the first motor, the carrier plate being fixed to the top of the first turntable.

[0011] Optimally, the feeding assembly includes at least two sets of feeding support mechanisms mounted on the top of the support box and a feeding mechanism disposed between the feeding support mechanisms, the feeding mechanism being used to clamp the blade on the feeding support mechanism and place it on the carrier plate.

[0012] Optimally, the feeding assembly includes at least two sets of feeding support mechanisms mounted on the top of the support box and a feeding mechanism disposed between the feeding support mechanisms. The feeding mechanism is used to pick up the printed blades on the carrier plate and place them on the feeding support mechanisms.

[0013] Optimally, the feeding support mechanism includes a feeding support rod fixed to the top of the support box and a feeding tray that is elliptical and sleeved on the feeding support rod, with the blades stacked on the feeding tray.

[0014] Optimally, the feeding mechanism includes a second turntable rotatably mounted on the top of the support box, a first transfer plate liftably mounted above the second turntable, a first extension plate integrally connected to one side of the first transfer plate, and an electromagnet fixed to the bottom of the first extension plate.

[0015] Ideally, the feeding support mechanism includes a feeding support rod fixed to the top of the support box and a feeding tray that is liftably sleeved on the feeding support rod, and the printed blades are stacked on the feeding tray.

[0016] Optimally, the feeding mechanism includes a third turntable rotatably mounted on the top of the support box, a second transfer plate liftably mounted above the third turntable, a second extension plate integrally connected to one side of the second transfer plate, a mounting plate fixed to the bottom of the second extension plate, and a suction nozzle mounted on the bottom of the mounting plate.

[0017] Optimally, the feeding mechanism further includes a first guide post arranged around the top of the second turntable, a first guide sleeve embedded in the first transfer plate and fitted on the first guide post, a first limiting plate fixed to the top of the first guide post, and a first buffer sleeve fitted on the first guide post and fixed to the bottom of the first limiting plate.

[0018] Optimally, the feeding mechanism further includes a third guide post circumferentially disposed on the top of the third turntable, a third guide sleeve embedded in the second transfer plate and fitted on the third guide post, a second limiting plate fixed on the top of the third guide post, and a second buffer sleeve fitted on the third guide post and fixed at the bottom of the second limiting plate.

[0019] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0020] This utility model relates to a highly automated blade printing transfer structure. By setting up a feeding component, blades are picked up one by one and placed at the transition component. The transition component then transfers the blades to the printing press to complete the printing of the logo on the blade surface. After printing, the blades are transferred to the unloading component via the transition component, where the unloading component completes the unloading of the blades. The entire process is highly automated, realizing fully automated transfer of blades from feeding, printing to unloading. This improves the efficiency of blade feeding and picking, reduces the labor intensity of operators, and saves costs. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0030] like Figure 2 ,3 The diagram shows a schematic diagram and a front view of the transfer structure for blade printing according to this utility model. The transfer structure includes a support box 1, a transition assembly, a feeding assembly, and a discharging assembly. The support box 1 is a box structure welded from metal plates, and its interior is hollow to provide installation space for the drive components. The transition assembly, feeding assembly, and discharging assembly are all installed on the top of the support box 1.

[0031] The transition assembly includes a first motor 2, a first turntable 3, a carrier plate 4, a weight-reducing groove 5, and a carrier plate 6. The motor housing of the first motor 2 is fixed to the upper surface of the support box 1 by screws, and the motor shaft of the first motor 2 is set upward. The first turntable 3 is mounted on the motor shaft of the first motor 2 by key connection, and the first motor 2 drives the first turntable 3 to rotate.

[0032] The carrier disk 4 is disc-shaped and is fixed to the top of the first turntable 3 by screws. When the first motor 2 drives the first turntable 3 to rotate, it will drive the carrier disk 4 on it to rotate synchronously. Figure 1 As shown, the upper surface of the carrier 4 is divided into four stations, with an included angle of 90° between any two adjacent stations. There are four carrier plates 6, which are fixed to the upper surface of the carrier 4 by screws and are located at the four stations on the top of the carrier 4.

[0033] Figure 2 The diagram shows the positional relationship between the loading and unloading components. The station opposite the loading component is the printing station, where a solder paste printer is installed to print logos on the blades to be processed. To ensure consistent work cycle, four sets of stations are set on top of the carrier tray 4. Weight-reducing grooves 5 are distributed on top of the carrier tray 4 (located between the four sets of stations) and extend vertically through the carrier tray 4. By setting the weight-reducing grooves 5, the weight of the carrier tray 4 is reduced, which saves processing materials and reduces processing costs. Furthermore, by reducing the weight of the carrier tray 4, the energy output loss of the first motor 2 is reduced.

[0034] The feeding assembly is installed on the top of the support box 1 and located on one side of the carrier tray 4. The feeding assembly is used to clamp the blades to be processed and place the blades on the carrier plate 6 of the carrier tray 4. The feeding assembly includes a feeding support mechanism and a feeding mechanism. Both the feeding support mechanism and the feeding mechanism are installed on the upper surface of the support box 1, and there are at least two sets of feeding support mechanisms. The blades to be printed are stacked on the feeding support mechanisms. The feeding mechanism clamps the blades on the feeding support mechanisms and transfers the blades to the carrier plate 6 of the carrier tray 4. (By setting at least two sets of feeding support mechanisms, the working efficiency of blade feeding is improved. When the blades in one set of feeding support mechanisms are empty, the feeding mechanism continues to pick up blades from the other set of feeding support mechanisms. During this gap, the operator can replenish the empty feeding support mechanisms, avoiding the waste of time caused by stopping the machine to place blades.)

[0035] like Figure 4 , 5 As shown, each set of feeding support mechanisms includes a first lifting plate 17, a second guide post 18, a second guide sleeve 19, a feeding support rod 20, a feeding pallet 21, and a first lifting cylinder 22. There are multiple second guide sleeves 19, which are embedded in the top of the support box 1. The second guide post 18 passes through the second guide sleeve 19 in a vertical direction. By setting the second guide post 18 and the second guide sleeve 19 that cooperate with each other, the stability of the lifting movement of the feeding pallet 21 is improved.

[0036] The first lifting plate 17 is fixed to the bottom of the second guide column 18 by welding. When the first lifting plate 17 is installed at the bottom of the second guide column 18, the first lifting cylinder 22 pushes the first lifting plate 17 to rise and fall, and the first lifting plate 17 drives multiple second guide columns 18 to move synchronously, ensuring the consistency of the guide column movement.

[0037] The first lifting cylinder 22 is installed inside the support box 1 and connected to the first lifting plate 17. Specifically, the first cylinder mounting plate is fixed to the inner wall of the support box 1 by welding, and the first cylinder mounting plate is set horizontally inward. The cylinder body of the first lifting cylinder 22 is fixed to the first cylinder mounting plate by screws, and the piston rod of the first lifting cylinder 22 is fixed to the bottom of the first lifting plate 17 by welding. The first lifting cylinder 22 drives the first lifting plate 17 to rise, which in turn drives the second guide column 18 and the feeding plate 21 to rise, thereby providing blades for the feeding mechanism.

[0038] The feeding support rod 20 is vertically fixed to the top of the support box 1 by welding. The feeding tray 21 is fixed to the top of the second guide post 18 by welding. The blades to be printed are stacked on the upper surface of the feeding tray 21, and the stacked blades are all fitted onto the feeding support rod 20. The feeding support rod 20 limits the blades to prevent them from scattering and falling off from one side (e.g., ...). Figure 1The diagram shows the structure of the blade. A through hole is provided in the middle of the blade. The through hole in the middle of the blade is used to reduce the weight of the blade itself and improve its endurance and operability. When the blade is actually installed, the through hole in the middle of the stacked blades is inserted into the feeding support rod 20, and the diameter of the through hole is equal to the diameter of the feeding support rod 20.

[0039] When the feeding support mechanism is feeding material, each time the feeding mechanism clamps the uppermost blade of the feeding tray 21, the first lifting cylinder 22 drives the second guide column 18 to rise. The second guide column 18 drives the feeding tray 21, which is fixedly connected to it, to rise together by a distance corresponding to the thickness of one blade, so as to facilitate the feeding mechanism to clamp again.

[0040] The top of the support box is fixed with a support frame by screws. A CCD camera is installed on the top of the support frame and faces the side of the feeding tray 21. The CCD camera detects the presence of the topmost blade on the feeding tray 21 in real time. When the feeding mechanism picks up the blade, the CCD camera detects that the blade is missing and transmits the signal to the back-end controller (such as PLC). The controller then instructs the first lifting cylinder 22 to act, driving the second guide column 18 to raise the fixedly connected feeding tray 21 a fixed distance (corresponding to the thickness of one blade), so that the next blade reaches the picking position, which is convenient for the subsequent feeding mechanism to pick up.

[0041] The feeding mechanism includes a second turntable 7, a second motor 8, a first guide post 9, a first guide sleeve 10, a first transfer plate 11, a first extension plate 12, an electromagnet 13, a first limiting plate 14, a first buffer sleeve 15, and a first lifting cylinder 16. The second turntable 7 is rotatably mounted on the top of the support box 1. The motor housing of the second motor 8 is fixed to the bottom of the support box 1 by screws. The motor shaft of the second motor 8 passes through the support box 1 and is connected to the second turntable 7. The second motor 8 drives the second turntable 7 to rotate, thereby transferring the blades. The first guide post 9 is fixed to the top of the second turntable 7 by welding. The first guide sleeve 10 is embedded in the first transfer plate 11 and sleeved on the first guide post 9. By setting the first guide post 9 and the first guide sleeve 10 in a mutually cooperating manner, the stability of the lifting of the first transfer plate 11 is improved.

[0042] The cylinder body of the first lifting cylinder 16 is fixed to the top of the second turntable 7 by screws, and its piston rod is fixed to the bottom of the first transfer plate 11 by welding. The first lifting cylinder 16 drives the first transfer plate 11 to rise and fall to transfer the blades. The first extension plate 12 is integrally connected to one side of the first transfer plate 11. The electromagnet 13 is installed at the bottom of the first extension plate 12. The electromagnet 13 is used to pick up the metal blades on the loading tray 21 and place them on the carrier plate 6 of the carrier tray 4. (During operation, the electromagnet 13 is energized to generate magnetic force to pick up the metal blades on the top layer of the loading tray 21. After moving with the first transfer plate 11 to the top of the carrier plate 6 of the carrier tray 4, the power is cut off to release the blades, completing the placement.)

[0043] The first limiting plate 14 is fixed to the top of the first guide post 9 by welding. The first buffer sleeve 15 is fitted onto the first guide post 9 with an interference fit and abuts against the lower surface of the first limiting plate 14. The first buffer sleeve 15 is a rubber sleeve. When the first lifting cylinder 16 drives the first transfer plate 11 to rise to the end point, the first transfer plate 11 contacts the first buffer sleeve 15. The elastic deformation of the rubber sleeve absorbs the impact energy, reducing the impact of the first transfer plate 11 on the first limiting plate 14, thereby improving the service life of the first limiting plate 14 and the first guide post 9.

[0044] The feeding assembly is installed on the top of the support box 1 and on the other side of the carrier plate 4. The feeding assembly is used to clamp the printed blades on the transfer carrier plate 6. The feeding assembly includes a feeding support mechanism and a feeding mechanism. Both the feeding support mechanism and the feeding mechanism are installed on the upper surface of the support box 1, and there are at least two sets of feeding support mechanisms. The feeding mechanism clamps the printed blades on the carrier plate 6 and places them on the feeding support mechanism (by setting at least two sets of feeding support mechanisms, the working efficiency of blade feeding is improved. When one set of feeding support mechanisms is full of blades, the feeding mechanism places the blades in another empty set of feeding support mechanisms. In this gap, the operator can remove the printed blades from the feeding support mechanism, avoiding the waste of time caused by stopping the machine to remove the blades).

[0045] like Figure 4 , 6 As shown, each set of unloading support mechanisms includes a second lifting plate 34, a fourth guide post 35, a fourth guide sleeve 36, an unloading support rod 37, an unloading pallet 38, and a second lifting cylinder 39. There are multiple fourth guide sleeves 36, which are embedded in the top of the support box 1. The fourth guide post 35 passes through the fourth guide sleeve 36 in a vertical direction. By setting the mutually cooperating fourth guide posts 35 and fourth guide sleeves 36, the stability of the lifting movement of the unloading pallet 38 is improved.

[0046] The second lifting plate 34 is fixed to the bottom of the fourth guide column 35 by welding. By installing the second lifting plate 34 at the bottom of the fourth guide column 35, when the second lifting cylinder 39 pushes the second lifting plate 34 to rise and fall, the second lifting plate 34 drives multiple fourth guide columns 35 to move synchronously, ensuring the consistency of the guide column movement.

[0047] The second lifting cylinder 39 is installed inside the support box 1 and connected to the second lifting plate 34. Specifically, the second cylinder mounting plate is fixed to the inner wall of the support box 1 by welding, and the second cylinder mounting plate is set horizontally inward. The cylinder body of the second lifting cylinder 39 is fixed to the second cylinder mounting plate by screws, and the piston rod of the second lifting cylinder 39 is fixed to the bottom of the second lifting plate 34 by welding. The second lifting cylinder 39 drives the second lifting plate 34 to rise and fall, which in turn drives the fourth guide post 35 and the unloading plate 38 to rise and fall to receive the printed blade.

[0048] The feeding support rod 37 is vertically fixed to the top of the support box 1 by welding, and the feeding tray 38 is fixed to the top of the fourth guide post 35 by welding. The printed blades are stacked on the upper surface of the feeding tray 38, and the stacked blades are all fitted onto the feeding support rod 37. The feeding support rod 37 limits the blades to prevent them from scattering and falling off from one side (e.g., ...). Figure 1 The diagram shows the structure of the blade. A through hole is provided in the middle of the blade, and the diameter of the through hole is slightly larger than the diameter of the feeding support rod 37 to facilitate the falling of the blade.

[0049] The top of the feeding support rod 37 is provided with an inclined guide part, which ensures that the through hole of the blade can be smoothly inserted into the feeding support rod 37 when the printed blade is placed on the feeding support rod 37.

[0050] like Figure 6 The diagram shows the position of the feeding tray 38 when the blades are ejected. When the feeding tray 38 receives the blades, its initial position is the lowering limit position (at this time, its bottom surface is in contact with the upper surface of the fourth guide sleeve 36). After the blades on the feeding tray 38 are filled, the second lifting cylinder 39 pushes the second lifting plate 34 to rise. The second lifting plate 34 drives the fourth guide post 35 and the feeding tray 38 to rise synchronously to lift the blades that are stacked on the feeding tray 38 after printing, making it convenient for the operator to handle.

[0051] The feeding mechanism includes a third turntable 23, a third motor 24, a third guide post 25, a third guide sleeve 26, a second transfer plate 27, a second extension plate 28, a mounting plate 29, a suction nozzle 30, a second limiting plate 31, a second buffer sleeve 32, and a second lifting cylinder 33. The third turntable 23 is rotatably mounted on the top of the support box 1. The motor housing of the third motor 24 is fixed to the bottom of the support box 1 by screws. The motor shaft of the third motor 24 passes through the support box 1 and is connected to the third turntable 23. The third motor 24 drives the third turntable 23 to rotate, thereby transferring the blades. The third guide post 25 is fixed to the top of the third turntable 23 by welding. The third guide sleeve 26 is embedded in the second transfer plate 27 and sleeved on the third guide post 25. By setting the mutually cooperating third guide post 25 and third guide sleeve 26, the stability of the lifting of the second transfer plate 27 is improved.

[0052] The cylinder body of the second lifting cylinder 33 is fixed to the top of the third turntable 23 by screws. The piston rod of the second lifting cylinder 33 is fixed to the bottom of the second transfer plate 27 by welding. The second lifting cylinder 33 drives the second transfer plate 27 to rise and fall to transfer the blade. The second extension plate 28 is integrally connected to one side of the second transfer plate 27. The mounting plate 29 is fixed to the bottom of the second extension plate 28 by screws. The suction nozzle 30 is installed at the bottom of the mounting plate 29. The suction nozzle 30 is used to pick up the printed blades on the carrier plate 6 (during operation, the suction nozzle 30 uses negative pressure to pick up the printed blades on the carrier plate 6. After rotating with the third turntable 23 to the unloading support mechanism position, the negative pressure is released to release the blades).

[0053] The second limiting plate 31 is welded to the top of the third guide post 25. The second buffer sleeve 32 is fitted onto the third guide post 25 with an interference fit and abuts against the lower surface of the second limiting plate 31. The second buffer sleeve 32 is made of rubber. When the second lifting cylinder 33 drives the second transfer plate 27 to rise to the end point, the second transfer plate 27 contacts the second buffer sleeve 32. The elastic deformation of the rubber sleeve absorbs the impact energy, reducing the impact of the second transfer plate 27 on the second limiting plate 31, thereby improving the service life of the second limiting plate 31 and the third guide post 25.

[0054] In operation, the blade transfer structure of this utility model first places the blades in layers on the feeding support mechanism (specifically, the through holes of the blades pass through the feeding support rod 20, and the blades abut against the upper surface of the feeding tray 21). The second motor 8 drives the second turntable 7, the first transfer plate 11, and the first extension plate 12 to rotate above the feeding tray 21. The first lifting cylinder 16 drives the first transfer plate 11 and the first extension plate 12 to descend until the electromagnet 13 contacts the uppermost blade on the feeding tray 21. The electromagnet 13 is energized to generate magnetic force to attract the uppermost blade. Then the first lifting cylinder... 16 drives the first transfer plate 11 and the first extension plate 12 to rise and reset. The second motor 8 drives the second turntable 7, the first transfer plate 11 and the first extension plate 12 to rotate above the carrier plate 6. The electromagnet 13 is de-energized and places the blade on the carrier plate 6. The first motor 2 drives the carrier plate 4 to rotate and rotate the blade on the carrier plate 6 to the printing station. After the printing machine completes the printing of the logo, it rotates to the unloading mechanism. The suction nozzle 30 of the unloading mechanism uses negative pressure to pick up the printed blade and transfer it to the unloading support structure (the blade passes through the unloading support rod 37 and is supported by the unloading tray 38 at the bottom).

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
