Description

Technical Field

[0001] This invention relates to the field of blow molding machine technology, and in particular to a recycled preform preparation device for blow molding machines. Background Technology

[0002] A blow molding machine is a machine that blows bottles. In its simplest terms, it is a machine that can blow plastic granules (softened into liquid) or pre-made bottle preforms into bottles using certain processes.

[0003] In blow molding machines, preform sorting is a crucial part. After the preforms are fed by the elevator, they are sorted by the preform sorting device. However, during the sorting process, because the elevator lifts many preforms onto the sorting device, and the preforms are disordered, existing devices, while effectively sorting them, still have the problem of preform jamming. Jamming affects subsequent use. To avoid jamming, a new preform sorting device is needed to solve the above problems. At the same time, it can also return unsorted preforms to the elevator. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a recycled preform preparation device for blow molding machines.

[0005] This invention provides a preform preparation device for a blow molding machine, comprising: a feeding assembly, a lifting assembly mounted on the feeding assembly for lifting materials, and a preform preparation shell. The preform preparation shell contains a preform preparation mechanism for organizing the materials. A discharge assembly is located at the end of the preform preparation shell away from the lifting assembly. The preform preparation shell is inclined. A return mechanism is located within the preform preparation shell, used to guide irregularly shaped materials into the feeding assembly or the lifting assembly. The return mechanism includes a drop space within the preform preparation shell, a collection mechanism mounted within the preform preparation shell for collecting materials, and a feeding assembly mounted on the preform preparation shell. The feeding assembly is connected to the feeding assembly or the lifting assembly. The drop space is located above the collection mechanism, and the collection mechanism is located above the feeding assembly.

[0006] Preferably, the collecting mechanism includes a rotating component rotatably assembled inside the blanking shell and a conveyor belt disposed on the rotating component. The rotating component is a rotating rod, and there are two rotating rods symmetrical to each other. The blanking shell is also provided with a power source for driving the rotating component to rotate.

[0007] Preferably, the feeding assembly includes a collecting shell mounted on the outer shell of the blank and a guide tube mounted on the collecting shell. One end of the guide tube is connected to the collecting shell, and the other end is connected to the feeding assembly or the lifting assembly. The collecting shell is funnel-shaped.

[0008] Preferably, the feeding assembly includes a feeding shell installed on the ground, with an open end at the top, and the lifting assembly includes a feeding pipe connected to the feeding shell and a lifting machine installed on the feeding shell or the feeding pipe, the lifting machine being driven by a power source.

[0009] Preferably, the blanking shell is provided with a flow guide, which includes two rotating rollers installed inside the blanking shell. The gap between the two rotating rollers can be used to clamp the material. The blanking shell is provided with a power source for driving the rotating rollers to rotate. The power source can drive the two rotating rollers to rotate through planetary gears.

[0010] Preferably, the outer shell of the blank is provided with a guide plate, which is an inclined plate and is used to concentrate the material in the gap between the two rotating rollers.

[0011] Preferably, the blank handling shell is equipped with two mounting plates for cooperating with the rotating rollers. The mounting plates are symmetrical and the two rotating rollers are respectively mounted on the two mounting plates. The space between the mounting plates and the discharge assembly is a drop space. The blank handling shell is also equipped with two symmetrical positioning plates. The positioning plates are installed in the drop space. The gap between the two positioning plates is used to catch the material falling from the gap between the two rotating rollers. The positioning plates are inclined and the gap between the two positioning plates is used to guide the material to approach the discharge assembly.

[0012] Preferably, a baffle plate is installed on the blank shell, the baffle plate is located above the rotating roller, and a material passage space is reserved between the baffle plate and the rotating roller.

[0013] Preferably, a feeding mechanism is installed on the blanking shell. The feeding mechanism includes a power source installed on the blanking shell, a rotating shaft connected to the power source, and blades installed on the rotating shaft. The blades are located above the positioning plate and are used to strike misaligned materials. The power source is a motor.

[0014] Compared with related technologies, the present invention provides a recycled preform feeding device for a blow molding machine with the following advantages: In use, the device lifts the material into the preform feeding shell via a lifting component, then guides the material to the guiding component via a guide plate, clamping the material. As the material passes through the inclined preform feeding shell, it approaches the discharge component. During this process, misaligned material comes between two elongated positioning plates. The material then falls from the drop space. Material positioned directly above the moving material is struck by blades driven by a rotating shaft, causing excess material to fall onto the conveyor belt. The conveyor belt then returns the material to the guide tube, which in turn returns it to the feed shell or feed pipe, thus enabling refeeding and achieving material recycling.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0024] Please see Figures 1 to 5This invention provides a preform preparation device for a blow molding machine, comprising: a feeding assembly, a lifting assembly mounted on the feeding assembly for lifting materials, and a preform preparation shell 1. The preform preparation shell is provided with a preform preparation mechanism for organizing materials. A discharge assembly is provided at the end of the preform preparation shell 1 away from the lifting assembly. The preform preparation shell is inclined. A return mechanism is provided inside the preform preparation shell for guiding irregularly shaped materials into the feeding assembly or the lifting assembly. The return mechanism includes a drop space opened within the preform preparation shell, a collection mechanism mounted within the preform preparation shell for collecting materials, and a feeding assembly mounted on the preform preparation shell. The feeding assembly is connected to the feeding assembly or the lifting assembly. The drop space is located above the collection mechanism, and the collection mechanism is located above the feeding assembly.

[0025] The collecting mechanism includes a rotating component mounted inside the blanking shell 1 and a conveyor belt 8 mounted on the rotating component. The rotating component is a rotating roller 4, and there are two rotating rollers 4 symmetrical to each other. The blanking shell 1 is also provided with a power source for driving the rotating component to rotate.

[0026] In this embodiment, the collection mechanism can collect materials falling from the drop space and guide the materials to the feeding component, where the feeding component can then perform secondary return of the materials.

[0027] The feeding assembly includes a collecting shell installed on the blank shell 1 and a guide tube 2 installed on the collecting shell. One end of the guide tube 2 is connected to the collecting shell, and the other end is connected to the feeding assembly or the lifting assembly. The collecting shell is funnel-shaped.

[0028] In this embodiment, the guide pipe 2 and the collection shell can guide the material to flow back into the feed shell or feed pipe, so that the material can be fed again and the material can be returned to the feed shell or feed pipe.

[0029] The feeding assembly includes a feeding shell installed on the ground, with an open end at the top. The lifting assembly includes a feeding pipe connected to the feeding shell and a lifting machine installed on the feeding shell or the feeding pipe, the lifting machine being driven by a power source.

[0030] The blanking shell 1 is equipped with a flow guide, which includes two rotating rollers installed inside the blanking shell. The gap between the two rotating rollers can be used to clamp the material. The blanking shell 1 is equipped with a power source for driving the rotating rollers to rotate. The power source can drive the two rotating rollers to rotate through planetary gears.

[0031] In this embodiment, by rotating two rotating rollers, the material can be recycled between the two rotating rollers, thus forming a clamping effect on the material.

[0032] Inside the outer shell 1, there is a guide plate 6. The guide plate 6 is an inclined plate and is used to concentrate the material in the gap between the two rotating rollers.

[0033] The outer shell 1 of the blank handling unit is equipped with two mounting plates 5 for cooperating with the rotating rollers. The mounting plates 5 are symmetrical to each other. The two rotating rollers are respectively mounted on the two mounting plates 5. The space between the mounting plates 5 and the discharge assembly is the drop space. The outer shell 1 of the blank handling unit is also equipped with two symmetrical positioning plates. The positioning plates are installed in the drop space. The gap between the two positioning plates is used to catch the material falling from the gap between the two rotating rollers. The positioning plates are inclined. The gap between the two positioning plates is used to guide the material to approach the discharge assembly.

[0034] In this embodiment, when the material is transferred from the gap between the two rotating rollers to the gap between the two positioning plates, the material will continue to move and move closer to the discharge assembly. The discharge assembly is a conveying hole opened on the blank shell 1, and the conveying hole is connected to the next external process.

[0035] A baffle plate 3 is installed on the outer shell 1 of the blank. The baffle plate 3 is located above the rotating roller, and a material passage space is reserved between the baffle plate 3 and the rotating roller.

[0036] In this embodiment, when the material comes from the elevator into the blanking shell 1, the material is disordered. At this time, the material is sorted by the rotating rollers and will come into the gap between the two rotating rollers. In order to prevent the material from falling from the elevator into the blanking shell 1, the baffle plate 3 can effectively block the material and achieve the blanking effect.

[0037] A feeding mechanism is installed on the blanking shell 1. The feeding mechanism includes a power source installed on the blanking shell 1, a rotating shaft connected to the power source, and blades 7 installed on the rotating shaft. The blades 7 are located above the positioning plate and are used to strike misaligned materials. The power source is a motor.

[0038] In this embodiment, the material placed directly above the moving material can be driven by the blades 7 of the rotating shaft. The blades 7 will strike the misaligned material, and the excess material will fall onto the conveyor belt 8. The conveyor belt 8 will then bring the material back into the guide tube 2.

[0039] The circuits and controls involved in this invention are all existing technologies and will not be described in detail here.

[0040] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
