Description

Technical Field

[0001] This utility model relates to the field of plastic bottle processing, and in particular to a waste shearing device for processing plastic bottle blow molding machines. Background Technology

[0002] In the blow molding production of plastic bottles, excess plastic waste often adheres to the bottle mouth, bottom, and other areas after the bottle body is demolded.

[0003] Current common processing methods mainly rely on semi-automatic equipment, which has the following significant drawbacks:

[0004] The small waste material after cutting is easily mixed with the finished bottle, often requiring additional vibrating screens or manual sorting processes to separate them. Furthermore, the bottles may be contaminated or scratched during the sorting process.

[0005] The existing functions of clamping, conveying, shearing, and collecting are usually completed by multiple independent devices, resulting in poor coordination between processes and affecting the smoothness of production.

[0006] Therefore, we propose a waste shearing device for processing plastic bottle blow molding machines to solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a shearing device for processing plastic bottle blow molding machines, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a shearing waste device for processing plastic bottle blow molding machines, comprising:

[0009] The main frame, on which connecting frames are mounted;

[0010] A guide frame is installed in the main frame and the connecting frame, and a waste outlet is opened on the guide frame;

[0011] A support base is located on one side of the main frame and is equipped with a slide rail.

[0012] Two sets of movable frames, the bottoms of which are slidably connected to the slide rails on the support base via sliding grooves;

[0013] The two sets of movable frames are respectively equipped with a first mounting frame and a second mounting frame, which are used to move towards each other to clamp the plastic bottle. After clamping, the support seat drives the whole to move longitudinally to transport the plastic bottle to the top of the guide frame.

[0014] A shearing mechanism, disposed on the first mounting frame and / or the second mounting frame, is used to shear waste material on the plastic bottle when the plastic bottle is conveyed above the guide frame.

[0015] Preferably, the waste inlet is provided with multiple parallel blocking rods.

[0016] Preferably, the distance between adjacent blocking bars is less than the diameter of the plastic bottle body.

[0017] Preferably, one end of the guide frame is provided with a downwardly inclined feeding port.

[0018] Preferably, the first mounting bracket is provided with a first lower bracket and a first upper bracket on one side, and the second mounting bracket is provided with a second lower bracket and a second upper bracket corresponding to the first lower bracket and the first upper bracket.

[0019] Preferably, the shearing mechanism includes:

[0020] The upper and lower shear plates are mounted on the first mounting frame.

[0021] The upper and lower bonding plates are fixedly mounted on the second mounting bracket and correspond to the positions of the upper and lower shearing plates.

[0022] Preferably, a first cylinder and a second cylinder are mounted on the other side of the first mounting bracket, and the output ends of the first cylinder and the second cylinder are respectively mounted to the upper shear plate and the lower shear plate.

[0023] Preferably, the first lower card holder and the first upper card holder are configured to correspond in size to the second lower card holder and the second upper card holder for the plastic bottle.

[0024] Preferably, the upper and lower shear plates are provided with guide rods, and the first mounting bracket is provided with guide holes for the guide rods to slide through.

[0025] The technical effects and advantages of this utility model are as follows:

[0026] The two sets of moving frames are controlled to move towards each other, driving the first and second mounting frames to clamp the plastic bottles. After clamping, the entire clamping unit and the plastic bottles are synchronously and smoothly transported to the shearing station above the guide frame by the longitudinally movable support base. The shearing action is completed by the shearing mechanism driven by the cylinder.

[0027] Through the design of the guide frame and waste inlet, during shearing, the bottle is suspended above the blocking bar with a specific gap. After shearing, the waste falls directly through the gap of the blocking bar and is collected, while the bottle body is supported because its diameter is larger than the gap. The bottle can automatically roll into the finished product collection channel along the inclined discharge port under the force of gravity or the push of subsequent bottles. It is automatically separated after the shearing action is completed, without the need for additional sorting process. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model provides, for example Figures 1-7 The device shown is a shearing waste device for processing plastic bottle blow molding machine, including a main frame 1, a guide frame 3, a movable frame 4 and a support base 7, and a connecting frame 2 is installed on the main frame 1;

[0038] The guide frame 3 is installed in the main frame 1 and the connecting frame 2. The connecting frame 2 is installed on the main frame 1 and a transparent observation acrylic plate is installed on the connecting frame 2. The acrylic plate facilitates the observation of the plastic bottle waste shearing process from the side. The guide frame 3 has a waste port 31 with multiple parallel blocking rods 32 in the waste port 31. The distance between adjacent blocking rods 32 is less than the diameter of the plastic bottle body. The sheared waste falls through the gap between the blocking rods 32 in the waste port 31.

[0039] At this time, the plastic bottle rolls along the blocking bar 32. One end of the guide frame 3 is provided with a downwardly inclined discharge port 33. The plastic bottle rolls from the blocking bar 32 to the discharge port 33 and is then collected by rolling through the discharge port 33, thus separating the waste and the plastic bottle.

[0040] Support base 7 is located on one side of main frame 1 and has slide rail 41 on it;

[0041] Two sets of movable frames 4 are slidably connected at their bottoms to slide rails 41 on support bases 7 via sliding grooves;

[0042] A drive motor 71 is installed on one side of the support base 7. The moving frame 4 is connected to a connecting base 73. The connecting base 73 is connected to a corresponding rack 72. Gears mesh between the two sets of racks 72. The drive motor 71 drives the gear transmission, which drives the racks 72 to move in opposite directions, thereby controlling the moving frame 4 to move in opposite directions.

[0043] Example 1: A first mounting frame 5 and a second mounting frame 6 are respectively installed on two sets of movable frames 4 for moving towards each other to clamp plastic bottles. After clamping, the support base 7 drives the whole to move longitudinally to transport the plastic bottles to the top of the guide frame 3.

[0044] A shearing mechanism, mounted on the first mounting frame 5 and / or the second mounting frame 6, is used to shear waste material on the plastic bottle when the plastic bottle is conveyed above the guide frame 3.

[0045] By pushing the support base 7, the moving frame 4 is moved towards the main frame 1, pushing the first mounting frame 5 and the second mounting frame 6 to clamp the plastic bottle directly above the guide frame 3. After the plastic bottle is in place, the first mounting frame 5 and the second mounting frame 6 separate, and the plastic bottle is placed on the guide frame 3. Then, the moving frame 4 is pulled back, and the first mounting frame 5 and the second mounting frame 6 are moved back. This makes it easy to control the first mounting frame 5 and the second mounting frame 6 to clamp the plastic bottle that has been processed by the blow molding machine, and it is convenient to repeatedly process the plastic bottle waste.

[0046] Specifically disclosed, the support base 7 can be moved longitudinally by controlling the movement of an electric rod or a cylinder.

[0047] Example 2: A first lower bracket 51 and a first upper bracket 52 are provided on one side of the first mounting bracket 5, and a second lower bracket 61 and a second upper bracket 62 are provided on the second mounting bracket 6 corresponding to the first lower bracket 51 and the first upper bracket 52;

[0048] The first lower card holder 51 and the first upper card holder 52 are sized to correspond with the second lower card holder 61 and the second upper card holder 62 of the plastic bottle. The first mounting bracket 5 and the second mounting bracket 6 move towards each other. Under the opposite movement of the first mounting bracket 5 and the second mounting bracket 6, the first lower card holder 51 and the first upper card holder 52 on the first mounting bracket 5 move towards the second lower card holder 61 and the second upper card holder 62 on the second mounting bracket 6.

[0049] Furthermore, since the first lower clamping seat 51 is set to correspond to the second lower clamping seat 61, and the first upper clamping seat 52 is set to correspond to the second upper clamping seat 62, when the first lower clamping seat 51 moves to clamp the lower outer periphery of the plastic bottle, and at the same time the first upper clamping seat 52 moves to clamp the upper end of the plastic bottle, the upper and lower ends of the plastic bottle are clamped and fixed between the first mounting bracket 5 and the second mounting bracket 6. The simultaneous clamping of the upper and lower ends ensures the stability of the plastic bottle. Since the dimensions of the first lower clamping seat 51 and the first upper clamping seat 52 correspond to the plastic bottle, and the first lower clamping seat 51 and the second lower clamping seat 61 are set to correspond to the lower end of the plastic bottle, and the first upper clamping seat 52 and the second upper clamping seat 62 are set to correspond to the upper end of the plastic bottle, the position of the plastic bottle can be calibrated by clamping and positioning.

[0050] This is because the upper and lower ends of the plastic bottle are clamped and positioned at corresponding locations, ensuring that the bottle is always clamped in the same stable position each time it is clamped. This further guarantees that the plastic bottle is always in the same position between the first mounting bracket 5 and the second mounting bracket 6, improving the accuracy of subsequent cutting.

[0051] The shearing mechanism includes:

[0052] The upper shear plate 53 and lower shear plate 54 are set on the first mounting frame 5;

[0053] The upper bonding plate 63 and the lower bonding plate 64 are fixedly mounted on the second mounting bracket 6 and correspond to the positions of the upper shearing plate 53 and the lower shearing plate 54.

[0054] On the other side of the first mounting bracket 5, a first cylinder 55 and a second cylinder 56 are mounted, and the output ends of the first cylinder 55 and the second cylinder 56 are respectively mounted to the upper shear plate 53 and the lower shear plate 54.

[0055] Guide rods are provided on the upper shear plate 53 and the lower shear plate 54, and guide holes are provided on the first mounting bracket 5 for the guide rods to slide through. The guide rods are used to improve the stability of the movement of the upper shear plate 53 and the lower shear plate 54.

[0056] The upper shear plate 53 and the lower shear plate 54 are positioned to correspond to the waste material on the plastic bottle. The upper shear plate 53 and the lower shear plate 54 are controlled by the first cylinder 55 and the second cylinder 56 to move to the upper bonding plate 63 and the lower bonding plate 64. As the upper shear plate 53 and the lower shear plate 54 move, they pass over the plastic bottle and cut the waste material on the plastic bottle.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
