Description

Technical Field

[0001] The utility model relates to the technical field of bottle blowing machine production, in particular to a feeding device for bottle blowing machines. Background Art

[0002] The bottle blowing machine is a device that blows the preform into a bottle through high-pressure gas. After the bottle is formed, it needs to be unloaded. At present, the bottle is taken off the preform seat by a robot with a flipping mechanism, and then flipped and placed on the conveying device or directly released outside the machine. It has the following problems:

[0003] 1. If the robot is released directly, the formed bottles will accumulate on the ground, which is not conducive to subsequent collection and inspection. At the same time, the free fall process will cause bumps and dents;

[0004] 2. At present, most conveying devices are conveyor belts. After the formed bottles are placed on the conveyor belts, the conveyor belts lack guide facilities, and displacement is easy to occur during the start-stop and conveying process, causing the bottles to topple or fall, which is not conducive to subsequent automated detection and collection. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a feeding device for a bottle blowing machine with a simple structure, stable feeding guide and convenient operation.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A feeding device for a bottle blowing machine comprises a conveyor belt bracket and a conveyor belt installed on the conveyor belt bracket.

[0008] The conveyor belt support is provided with a material unloading guide structure and a conveying guide structure in sequence along the conveying direction of the conveyor belt. The material unloading guide structure and the conveying guide structure each include two synchronous conveying components. The two synchronous conveying components of the material unloading guide structure are respectively connected to the conveyor belt support through a flipping component. The synchronous conveying components of the conveying guide structure are fixedly mounted on the conveyor belt support. A conveying channel is formed between the material unloading guide structure and the conveying guide structure.

[0009] In this way, in the initial state, the flipping assembly drives the unloading synchronous conveying assembly to flip outward. After the bottle blank is blown, the robot clamps the bottle and moves it above the conveyor belt to avoid interference between the bottle and the unloading synchronous conveying assembly. After that, the robot is released and the bottle falls on the conveyor belt. The flipping assembly is reset to drive the unloading synchronous conveying assembly to flip inward to face the conveying guide structure. The conveyor belt starts, the synchronous conveying assembly starts, and the bottle is conveyed. During transportation, stability can be improved.

[0010] Among them, the synchronous conveying assembly includes a frame, with a driving shaft and a driven shaft respectively arranged at both ends of the frame. Both ends of the driving shaft and the driven shaft are connected to the frame through bearing seats. A driven sprocket is fixed to the upper end of the driving shaft. A first servo motor is fixedly installed on the frame, and a driving sprocket is fixedly installed on the output shaft of the first servo motor. The driving sprocket and the driven sprocket are connected by a chain; a number of driving pulleys are fixedly installed on the driving shaft at intervals, and a number of driven pulleys are fixedly installed on the driven shaft at intervals. The driving pulley and the driven pulley arranged opposite to each other are connected by a synchronous belt.

[0011] Among them, the synchronous conveying assembly further includes a number of support rollers. The support rollers penetrate through the synchronous belt, and both ends of the support rollers are connected to the support seats through bearings. The support seats are fixedly installed on the frame, and the support rollers are in contact with the synchronous belt.

[0012] Among them, the flipping assembly includes two flipping seats fixedly installed on the conveyor belt support. An ear seat is fixed to the lower end of the frame. The ear seat and the flipping seat are connected by a flipping shaft, and a torsion spring is fixed between the ear seat and the flipping seat. A second servo motor is fixedly installed on the flipping seat through a motor seat. A winding roller is fixed to the output shaft of the second servo motor. One end of a pulling rope is fixedly connected to the winding roller, and the other end of the pulling rope is fixedly connected to the frame.

[0013] Among them, a guide arm is fixed to the flipping seat. A guide groove is formed in the guide arm, and a guide shaft rotates in the guide groove. The pulling rope is in contact with the guide shaft.

[0014] Among them, when the frame of the blanking guiding structure is arranged vertically, the frame is in contact with the flipping seat.

[0015] In summary, the blanking device for the bottle blowing machine has the advantages of simple structure, stable blanking guiding, and convenient operation. Brief Description of the Drawings

[0020] The present utility model will be further described in detail below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0021] As Figures 1-4 shown, a blanking device for a blow molding machine includes a conveyor belt support 1 and a conveyor belt 2 installed on the conveyor belt support. The conveyor belt support is sequentially provided with a blanking guiding structure 3 and a conveying guiding structure 4 along the conveying direction of the conveyor belt. Both the blanking guiding structure and the conveying guiding structure include two synchronous conveying components. The two synchronous conveying components of the blanking guiding structure are respectively connected to the conveyor belt support through a flipping component 5. The synchronous conveying components of the conveying guiding structure are fixedly installed on the conveyor belt support. A conveying channel is formed between the blanking guiding structure and the conveying guiding structure.

[0022] In this way, in the initial state, the flipping component drives the blanking synchronous conveying component to flip outwards. After the bottle preform is blown, the manipulator clamps the bottle 6 and moves it above the conveyor belt to avoid interference between the bottle and the blanking synchronous conveying component. Then, the manipulator releases, and the bottle falls on the conveyor belt. The flipping component resets and drives the blanking synchronous conveying component to flip inwards until it is directly opposite to the conveying guiding structure. The conveyor belt starts, and the synchronous conveying component starts to convey the bottle. During the conveying process, the stability can be improved.

[0023] During implementation, the synchronous conveying component includes a frame 11. The two ends of the frame are respectively provided with a driving shaft 12 and a driven shaft 13. Both ends of the driving shaft and the driven shaft are connected to the frame through bearing seats. A driven sprocket 14 is fixed to the upper end of the driving shaft. A first servo motor 15 is fixedly installed on the frame. A driving sprocket 16 is fixedly installed on the output shaft of the first servo motor. The driving sprocket and the driven sprocket are connected by a chain 17. A plurality of driving pulleys 18 are fixedly installed on the driving shaft at intervals. A plurality of driven pulleys 19 are fixedly installed on the driven shaft at intervals. The driving pulley and the driven pulley arranged opposite to each other are connected by a synchronous belt 20.

[0024] In this way, when synchronously conveying the bottle, the synchronous belt moves synchronously and in the same direction as the conveyor belt to stably convey the bottle. The first servo motor drives the driving shaft to rotate through the sprocket and chain structure, and drives the synchronous belt to move synchronously through the pulley and synchronous belt structure, realizing the stable conveying of the bottle.

[0025] During implementation, the synchronous conveying assembly further includes a number of support rollers 21. The support rollers penetrate through the synchronous belt. Both ends of the support rollers are connected to the support seats 22 through bearings. The support seats are fixedly installed on the frame, and the support rollers are in contact with the synchronous belt, providing a stable supporting force for the synchronous belt and better stably conveying the bottles.

[0026] During implementation, the flipping assembly includes two flipping seats 23 fixedly installed on the conveyor belt support. An ear seat 24 is fixed to the lower end of the frame. The ear seat and the flipping seat are connected by a flipping shaft, and a torsion spring is fixed between the ear seat and the flipping seat. A second servo motor 25 is fixed to the flipping seat through a motor seat. A winding roller 26 is fixed to the output shaft of the second servo motor. One end of a pulling rope 27 is fixedly connected to the winding roller, and the other end of the pulling rope is fixedly connected to the frame. The second servo motor drives the winding roller to rotate, winds the pulling rope, and pulls the frame through the pulling rope to achieve the outward flipping of the frame. During reset, the second servo motor rotates in the reverse direction to relax the pulling rope, and the torsion spring drives the frame to reset.

[0027] During implementation, a guide arm 28 is fixed to the flipping seat. The guide arm is provided with a guide groove, and a guide shaft rotates in the guide groove. The pulling rope is in contact with the guide shaft, facilitating the guiding and supporting of the pulling rope.

[0028] During implementation, when the frame of the blanking guiding structure is vertically arranged, the frame is in contact with the flipping seat, facilitating the limiting of the frame in place after flipping.

[0029] Specifically, it further includes a PLC controller for controlling the actions of the electrical components therein.

[0030] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, the present utility model also intends to include these changes and modifications.
