Description

Technical Field

[0001] This utility model relates to the field of blister tray production technology, specifically to a quick ejection and detachment device for blister trays. Background Technology

[0002] After the blister tray is demolded during production, it is connected to the plastic sheet through multiple connection points in four directions. An ejector device is needed to push the blister tray out, simultaneously severing these connection points. In existing equipment, a suction rod descends and approaches the plastic tray, using negative pressure to lift it. The suction rod then drives the tray downwards to achieve ejection and detachment. However, because the plastic sheet is relatively loose during transport, the success rate of directly ejecting the blister tray by continuously providing negative pressure and descending is unpredictable. Instead, PLC-based time-delay control is required to ensure the suction rod holds the tray. This entire process is time-consuming and inefficient. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a quick ejection and detachment device for blister trays, which greatly reduces the detachment time of blister trays and ensures the success rate of detachment operations.

[0004] The technical solution of this utility model is as follows: a quick ejection and release device for a blister tray, comprising a frame, a pressing mechanism, an upper support mechanism, a lifting mechanism, and an adsorption rod. The upper end of the frame is a worktable, and the middle of the worktable has a vertically penetrating ejection area. Both sides of the worktable on the ejection area have side-opening receiving slots. There are two pressing mechanisms symmetrically installed on the upper end of the worktable on both sides of the ejection area. The output end of the pressing mechanism passes downward through the worktable and enters the receiving slot. There are two upper support mechanisms symmetrically installed on the lower end of the worktable on both sides of the ejection area. The output end of the upper support mechanism passes upward through the worktable and enters the receiving slot. The two upper support mechanisms are located between the two pressing mechanisms. The top of the frame is provided with a top plate. The lifting mechanism is installed on the upper end of the top plate. The output end of the lifting mechanism passes downward through the top plate and is connected to the adsorption rod. The adsorption rod can pass downward through the ejection area between the two upper support mechanisms.

[0005] Furthermore, the pressing mechanism includes a pressing cylinder and a pressure plate. The pressing cylinder is installed on the upper end of the workbench, and the output end of the pressing cylinder passes downward through the workbench into the receiving groove and connects with the pressure plate.

[0006] Furthermore, it also includes a tray, which is mounted in a receiving groove, and a pressure plate can press down against the tray.

[0007] Furthermore, the upper support mechanism includes an upper support cylinder and a push plate. The upper support cylinder is installed at the lower end of the workbench, and the output end of the upper support cylinder passes upward through the workbench into the receiving groove and connects with the push plate.

[0008] Furthermore, a roller is rotatably connected to the upper end of the push plate.

[0009] Furthermore, the lifting mechanism includes a motor, a guide rail, and a bracket. The motor is mounted on the upper end of the top plate, and the top plate is provided with a guide groove. The guide rail is slidably connected to the guide groove. The side of the guide rail is provided with a toothed structure that is connected to the motor drive. The bracket is fixedly connected to the lower end of the guide rail, and the suction rod is installed in the bracket.

[0010] Furthermore, the top plate is provided with a rotating seat, and the motor output end is rotatably connected to the rotating seat.

[0011] Furthermore, a suction cup is provided at the lower end of the adsorption rod.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the upper support mechanism straightens the plastic sheet, so that the blister tray that has not been removed from the plastic sheet is also pulled accordingly. The blister tray welcomes the suction rod in a horizontal position. When the suction rod maintains the negative pressure suction and moves downward, it can directly suck up the blister tray and push it out of the plastic sheet. Compared with the traditional method, there is no need to wait for the suction rod to suck up the blister tray before the removal operation, which greatly reduces the removal time of the blister tray and avoids the situation where the suction rod cannot successfully suck up the blister tray, thus ensuring the success rate of the removal operation.

[0020] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] like Figure 1-5As shown, a rapid ejection and release device for a blister tray includes a frame 1, a pressing mechanism, an upper support mechanism, a lifting mechanism, and a suction rod 12. The upper end of the frame 1 is a worktable 2, with a vertically extending ejection area in the middle. Both sides of the worktable 2 on either side of the ejection area have side-opening receiving grooves 201. The blister tray, after being demolded during blister forming, enters the device along with the plastic sheet. The plastic sheet is positioned on both sides within the receiving grooves 201, and the blister tray 6 is ejected from the ejection area. Two pressing mechanisms are symmetrically installed on the ejection area. At the upper ends of the worktables 2 on both sides of the material removal area, the output end of the pressing mechanism passes downward through the worktable 2 and enters the receiving groove 201. The pressing mechanism can press down on both sides of the plastic sheet. There are two upper support mechanisms, symmetrically installed at the lower ends of the worktables 2 on both sides of the material removal area. The output end of the upper support mechanism passes upward through the worktable 2 and enters the receiving groove 201. The two upper support mechanisms are located between the two pressing mechanisms. After the pressing mechanism presses down on the plastic sheet, the upper support mechanism can support the plastic sheet between the two pressing mechanisms, thus stretching the plastic sheet between the two upper support mechanisms. The frame 1 is straight, providing favorable conditions for the detachment of the blister tray 6; the top of the frame 1 is provided with a top plate 3, and the lifting mechanism is installed on the upper end of the top plate 3. The output end of the lifting mechanism passes downward through the top plate 3 and is connected to the suction rod 12. The suction rod 12 is a hollow round rod, and its negative pressure is supplied uniformly by the workshop air pump. Its lower end can suck up the blister tray; when the suction rod 12 moves downward and abuts against the blister tray, the blister tray is sucked up by the suction rod 12 and moves downward with it. The blister tray quickly detaches from the plastic sheet and passes downward through the unpacking area; during this process... Because the upper support mechanism straightens the plastic sheet, the blister tray that has not yet come out of the plastic sheet is also pulled accordingly. The blister tray greets the suction rod 12 in a horizontal position. When the suction rod 12 maintains negative pressure suction and moves downward, it can directly suck up the blister tray and push it out of the plastic sheet. Compared with the traditional method, there is no need to wait for the suction rod 12 to suck up the blister tray before the detachment operation, which greatly reduces the detachment time of the blister tray and avoids the situation where the suction rod 12 cannot suck up the blister tray smoothly, thus ensuring the success rate of the detachment operation.

[0022] In the above embodiment, the pressing mechanism includes a pressing cylinder 4 and a pressure plate 5. The pressing cylinder 4 is installed on the upper end of the workbench 2. The output end of the pressing cylinder 4 passes downward through the workbench 2 into the receiving groove 201 and connects with the pressure plate 5. The pressure plate 5 presses down on the plastic sheet. The lower end surface of the pressure plate 5 can be made of plastic to increase the static friction between the pressure plate 5 and the plastic sheet. The pressing mechanism also includes a support plate 6, which is mounted in the receiving groove 201. The pressure plate 5 can abut against the support plate 6 downward. The support plate 6 is used to support the pressure plate 5 and raise the support point to the upper end of the upper support mechanism. This prevents the plastic sheet from being too far from the bottom of the receiving groove 201 when it is mounted on the upper support mechanism, which would cause the pressing mechanism to fail to press down on the plastic sheet smoothly. The upper support mechanism includes an upper support cylinder 7 and a push plate 8. The upper support cylinder 7 is installed at the lower end of the workbench 2. The output end of the upper support cylinder 7 passes upward through the workbench 2 and enters the receiving groove 201 and is connected to the push plate 8. The push plate 8 is used to support and straighten the bottom of the plastic sheet. The upper end of the push plate 8 is rotatably connected to a roller 9. The roller 9 is used to support the plastic sheet. The roller 9 rolls with the plastic sheet during the process of supporting it, which transforms sliding friction into rolling friction, reduces the resistance when supporting it, and improves the smoothness of supporting it. The lifting mechanism includes a motor 10, a guide rail 14, and a bracket 11. The motor 10 is mounted on the upper end of the top plate 3. The top plate 3 has a guide groove 301, and the guide rail 14 is slidably connected to the guide groove 301. The side of the guide rail 14 has a toothed structure 1401 that is connected to the motor 10 for transmission. The toothed structure 1401 meshes with the gear 1001 of the motor 10. The bracket 11 is fixedly connected to the lower end of the guide rail 14. The adsorption rod 12 is installed in the bracket 11 with nuts, one above the other, for easy adjustment and disassembly. The motor 10 can drive the guide rail 14 to slide up and down and drive the adsorption rod 12 to push out the blister tray. The top plate 3 has a rotating seat 16, and the output end of the motor 10 is rotatably connected to the rotating seat 16, providing force support for the gear 1001 at the output end of the motor 10, preventing the gear 1001 from being deformed or broken due to long-term bearing the weight of the guide rail 14. The lower end of the adsorption rod 12 has a suction cup 13, which provides a larger adsorption area and ensures stable and reliable adsorption. The guide rail 14 is provided with a limiting screw 15 on its side. The limiting screw 15 can abut against the top plate 3 to provide a travel limit for the guide rail 14.

[0023] Description of the working principle of this utility model:

[0024] Under the conveying of the traction device, the blister tray, after being demolded by the blister forming process, enters the device along with the plastic sheet. At this time, both sides of the plastic sheet are located between the pressure plate 5 and the support plate 6. Under the push of the pressing cylinder 4, the pressure plate 5 presses the plastic sheet tightly onto the support plate 6. Then, the supporting cylinder 7 pushes the roller 9 upward to press against the plastic sheet, straightening the plastic sheet that was originally loose between the two pressing mechanisms, thereby leveling the blister tray located in the plastic sheet. Driven by the motor 10, the guide rail 14 slides down along the guide groove 301. At the same time, the suction rod 12 continuously provides negative pressure under the supply of the workshop air pump. The moment the suction rod 12 contacts the blister tray, the blister tray is sucked by the suction rod 12 and falls down with the suction rod 12. The connection point between the plastic tray and the plastic sheet is broken, and the blister tray detaches from the plastic sheet. The blister tray descends with the suction rod 12 to about 3cm above the preset conveyor belt. The suction rod 12 releases, allowing the blister tray to fall onto the conveyor belt. During the reciprocating suction and ejection operation of the suction rod 12, depending on the shape and thickness of the blister tray, the motor 10 reduces a certain pulse signal each time it drives the guide rail 14 downward. That is, as the blister trays are stacked higher and higher, the suction rod 12 will adjust its lower limit accordingly to ensure that the suction rod 12 can always descend to about 3cm above the previous ejected blister tray, ensuring that the blister trays can form a tight stacking relationship. When a certain number are stacked, the conveyor belt will transport them laterally for re-stacking. It should be emphasized that the use of conventional control methods such as PLC or microcontroller to adaptively adjust the pressing mechanism, supporting mechanism, lifting mechanism, and suction action of the suction rod 12 to achieve continuous operation are all conventional technical methods and will not be elaborated further.

[0025] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
