Description
Technical Field
[0001] This utility model relates to the technical field of plastic bottle processing equipment, and more specifically, to an environmentally friendly finished product transfer device for plastic bottle production. Background Technology
[0002] In the current mechanized processing of plastic bottles, several preforms are first arranged in a feeding hopper and transported to the front of a robotic arm. The robotic arm then reverses the flow and clamps the preforms onto the preform holder end of a heated conveyor belt. The preforms on the conveyor belt are preheated through heating ducts. After several heating stages, the preforms soften and enter the forming mold of a blown film machine, where they are blown into the desired shape of a medicine bottle or dairy bottle. Finally, the robotic arm reverses the flow again and flips the finished plastic bottles onto the unloading track. Under the influence of gravity, the finished plastic bottles fall sequentially into a transfer frame. Workers push the transfer frame to transport the stacked finished plastic bottles to the packaging workshop.
[0003] The existing transfer frames have the following problems in actual use: First, their internal structure is a simple frame without any cushioning design. During the fall of the finished plastic bottles, they will usually collide, which can easily cause some bottles to deform. Second, the finished plastic bottles are stacked one on top of the other inside the transfer frame. Since the sides of the plastic bottles are curved, when the transfer frame is not full, the plastic bottles inside the frame are prone to shaking and squeezing during the transfer process, causing some plastic bottles to be damaged. Subsequently, the plastic bottles that do not meet the requirements will be discarded by the screening personnel, which is not environmentally friendly and will also waste raw materials. Utility Model Content
[0004] The purpose of this invention is to provide an environmentally friendly finished product transfer device for plastic bottle production. This device has a special buffer structure that can be connected to the existing feeding track to arrange finished plastic bottles in sequence. At the same time, it raises the transfer trough at a certain angle to reduce the shaking of the plastic bottles inside the transfer trough when it is not full, thereby improving the stability of the plastic bottles during the transfer process, reducing the number of defective products with deformed plastic bottle shells due to collision, and is more environmentally friendly, reducing the waste of raw materials.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An environmentally friendly finished product transfer device for plastic bottle production includes a blown film machine discharge conveyor belt. Several mold tops are evenly spaced on the discharge conveyor belt, with plastic bottles inverted on each mold top. A row of robotic arms is located on the outer side of the discharge conveyor belt. The robotic arms grip the plastic bottles and flip them forward to the outside of a fixed discharge trough. A rotating discharge trough is also located outside the fixed discharge trough. The rotating discharge trough is driven upward by a motor to clamp the row of plastic bottles together with the fixed discharge trough. A transmission chain is embedded in the inner side of the fixed discharge trough. The transmission chain drives the row of plastic bottles outward to the position of two parallel inclined downward discharge troughs. A transfer trough is located below the inclined downward discharge troughs. A buffer assembly is provided between the transfer trough and the inclined downward discharge troughs. The buffer assembly includes two connecting rods and several semi-circular ring frames.
[0007] As a further optimization of this solution, the lower ends of the two parallel downward-sloping feed troughs are connected to the upper surface of the support plate on the outer side of the cabinet via telescopic pillars.
[0008] As a further optimization of this solution, the two connecting rods are symmetrically distributed around the center of the semi-circular frame. The two connecting rods pass through the surface of several semi-circular frames from top to bottom, connecting the several semi-circular frames at equal intervals from top to bottom. The interior of the several semi-circular frames supports half of the outer area of the plastic bottle falling from the inclined downward material trough. The front and rear sides of the uppermost semi-circular frame are connected to telescopic brackets by locking bolts. The outer end of the telescopic bracket is connected to the concave bracket by locking bolts. The concave area of the concave bracket is engaged with the outside of the inclined downward material trough. The concave bracket is fixed to the outside of the inclined downward material trough by tightening nuts on the outside.
[0009] As a further optimization of this solution, the upper and lower ends of the telescopic bracket are telescopic sections and are fixedly mounted on both sides of the middle section with screws.
[0010] As a further optimization of this solution, a rectangular frame is provided below the transfer trough. One end of the rectangular frame is rotatably connected to the bottom of both sides of the transfer trough via rotating shafts on both sides. The other end of the rectangular frame is connected to a push-pull handle upward via a horizontal connecting rod. A connecting plate with a threaded through hole is provided inward at the middle position of the other end of the rectangular frame. A lifting stud is screwed upward into the threaded through hole inside the connecting plate. The top of the lifting stud lifts the other end of the transfer trough upward.
[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0012] In this utility model, by designing a buffer component and a concave card seat structure, the buffer component can be directly connected to the bottom of the downward-sloping material trough. The plastic bottles falling from the downward-sloping material trough are supported by two connecting rods and several semi-circular ring frames, and the plastic bottles are smoothly guided into the transfer trough in sequence, avoiding the plastic bottles falling directly into the transfer trough and causing collision damage and deformation.
[0013] This invention utilizes a rotating shaft and lifting stud structure to lift one end of the transfer trough at a certain angle, causing the plastic bottles inside to roll towards the other end of the trough. This reduces the shaking of the plastic bottles inside the transfer trough when it is not full, improves the stability of the plastic bottles during the transfer process, reduces the number of defective products with deformed plastic bottle shells due to collisions, is more environmentally friendly, and reduces the waste of raw materials.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0020] To address the issue that existing transfer devices have a simple frame structure without any cushioning, resulting in collisions during the descent of finished plastic bottles, which can easily deform some bottles, and that the curved sides of the plastic bottles can cause them to shake and be squeezed when the transfer device is not full, leading to damage to some bottles, which are then discarded by the screening personnel, is not environmentally friendly and also wastes raw materials.
[0021] like Figure 1 As shown, this application includes a blown film machine discharge conveyor belt, on which a plurality of mold heads 1 are equally spaced, and plastic bottles 5 are invertedly mounted on the mold heads 1. Rows of robotic arms 2 are arranged on the outer side of the discharge conveyor belt. Figure 1 In the process, the robotic arm 2 grips the plastic bottle 5 and flips it forward to the outside of the fixed discharge trough 3. The outside of the fixed discharge trough 3 is also provided with a rotating discharge trough 4. The rotating discharge trough 4 is driven by a motor to rotate upward and clamp the row of plastic bottles 5 together with the fixed discharge trough 3. A transmission chain is embedded in the inner side of the fixed discharge trough 3. The transmission chain drives the row of plastic bottles 5 to move outward to the position area of two parallel inclined downward discharge troughs 6. A transfer trough 8 is provided below the inclined downward discharge trough 6. A buffer component is provided between the transfer trough 8 and the inclined downward discharge trough 6.
[0022] like Figure 2 As shown, the buffer assembly includes two connecting rods 10 and several semi-circular frame bodies 9. The lower ends of the two parallel downward inclined material troughs 6 are connected to the upper surface of the support plate 7 on the outer side of the cabinet through telescopic support columns 8.
[0023] like Figure 3 As shown, two connecting rods 10 are symmetrically distributed around the center of the semi-circular frame 9. The two connecting rods 10 pass through the surface of several semi-circular frames 9 from top to bottom and connect the several semi-circular frames 9 at equal intervals from top to bottom. The interior of several semi-circular frames 9 supports half of the outer area of the plastic bottle 5 falling from the inclined downward material trough 6. The front and rear sides of the uppermost semi-circular frame 9 are connected to telescopic brackets 11 by locking bolts 12. The outer end of the telescopic bracket 11 is connected to the concave bracket 13 by locking bolts 12. The concave area of the concave bracket 13 is fitted into the outside of the inclined downward material trough 6. The concave bracket 13 is fixed to the outside of the inclined downward material trough 6 by tightening nuts 14 on the outside. The upper and lower ends of the telescopic bracket 11 are telescopic sections and are fixed to the sides of the middle section by screws.
[0024] like Figure 4 As shown, a rectangular frame 15 is provided below the transfer trough 8. One end of the rectangular frame 15 is rotatably connected to the bottom of both sides of the transfer trough 8 through the rotating shafts 16 on both sides. The other end of the rectangular frame 15 is connected to a push-pull handle 17 upward through a horizontal connecting rod. A connecting plate 18 with a threaded through hole is provided inward at the middle position of the other end of the rectangular frame 15. A lifting stud 19 is screwed upward into the threaded through hole inside the connecting plate 18. The top of the lifting stud 19 lifts the other end of the transfer trough 8 upward.
[0025] Specifically, the buffer assembly is connected via the concave bracket 13, and the installation angle of the two connecting rods 10 is adjusted by the upper and lower locking bolts 12, so that the upper ends of the two connecting rods 10 receive the outlet positions of the two inclined downward material troughs 6 and the lower ends extend into the transfer trough 8. When the transmission chain drives the row of plastic bottles 5 to move outward to the position of the two parallel inclined downward material troughs 6, the plastic bottles 5 vertically enter the area between the two connecting rods 10, and fall sequentially along the vertically spaced semi-circular annular frames 9, being guided into the transfer trough 8. At the same time, the top of the lifting stud 19 lifts the other end of the transfer groove 8 upward, causing the bottom surface of the transfer groove 8 to tilt at a certain angle. This causes the plastic bottles 5 that have entered the transfer groove 8 to roll towards the bottom of the other end of the transfer groove 8, reducing the shaking of the plastic bottles 5 inside the transfer groove 8 when it is not full. This improves the stability of the plastic bottles 5 during the transfer process. The buffer component buffers and guides the plastic bottles 5 to enter the transfer groove 8 smoothly, reducing the number of defective products with deformed outer shells due to collision. This is more environmentally friendly and reduces the waste of raw materials.
