Description

Technical Field

[0001] The invention belongs to the technical field of mechanical equipment and relates to a feeding turning device. Background Art

[0002] The blister machine, also known as the thermoplastic forming machine, is a machine that blister-forms heated and plasticized thermoplastic plastic coils such as PVC, PE, PP, PET, HIPS, etc. into packaging boxes, frames and other products of various shapes. It uses the vacuum suction generated by a vacuum pump to blister-form the heated and softened thermoplastic plastic sheets into various shapes of lunch boxes, vacuum covers, blister trays, bubble shells, etc. through molds. The continuous strip of plastic sheets is formed into products arranged in sequence after blister forming. After forming, they need to be transported to the cutting machine for cutting. The blister machine is downward blister forming, so the blister product has an opening facing upward and a bottom protruding downward. When the cutting machine is cutting, the bottom of the blister product needs to protrude upward. Therefore, the continuous strip of blister parts needs to be transported from the blister machine to the cutting machine and turned over.

[0003] For example, the patent document (application number: 201610095957.8) discloses a punching device for a food box, in which a flipping mechanism is provided on the top of the punching device. After the continuous strip of blister parts is formed by blister forming, it needs to be transported upward to the top of the punching device and transported along the top, and then flipped downward by a roller installed on the top, thereby realizing both the transportation and flipping of the blister parts. However, transporting from the top means that the blister parts need to be transported upward from the blister machine to the top of the punching device first, which has a high height and requires high energy consumption. During punching, the blister parts need to be flipped downward to a lower position, which is obviously a waste of energy. In addition, the cutting machine needs to accurately position the blister parts during cutting, while the roller only realizes flipping support. The blister parts need to be transported by other power components, and the position accuracy of the blister parts is poor, which affects the cutting quality. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and propose a feeding and flipping device to solve the problems that the existing feeding device is not accurate enough in conveying the blister pieces that need to be flipped and has high energy consumption.

[0005] The objective of the present invention can be achieved through the following technical solutions: a feeding turning device, comprising a frame body, characterized in that it also comprises a feeding frame and a guide frame both having a rotating shaft, the feeding frame and the guide frame are connected to the frame body through their own rotating shafts and can rotate, the two rotating shafts are arranged in parallel, and the feeding frame is lower than the guide frame, the feeding frame comprises a plurality of feeding push rods arranged in parallel with the rotating shafts, and the plurality of feeding push rods are evenly arranged around the rotating shaft of the feeding frame, and a material clamping gap is formed between two adjacent feeding push rods.

[0006] After the continuous strip of plastic sheets is formed by the blister forming machine, products such as lunch boxes are formed in an orderly and continuously arranged order. After forming, they need to be continuously transported to the cutting machine for cutting. The blister products formed by the blister forming machine have an opening facing upward and a bottom protruding downward. For this reason, the present application provides a feeding rack and a guide rack. When the continuous strip of blister parts is transported to the cutting machine, it is only turned over and enters the cutting machine. Specifically, the frame is arranged on one side of the blister forming machine, the feeding rack is closer to the blister forming machine, the feeding rack is lower, and the guide rack is higher. Taking the lunch box as an example, after the blister parts are formed on the blister forming machine, the opening of the lunch box faces upward and passes through the space at the bottom of the cutting machine, then goes around to the lower feeding rack, and then passes between the feeding rack and the guide rack, and then goes around the guide rack and flips over, and is transported to the cutting area of ​​the cutting machine in a roughly horizontal state. The feeding rack includes a plurality of feeding push rods which are evenly distributed circumferentially, and a material clamping gap is formed between adjacent feeding push rods, and the material clamping gap is also evenly distributed circumferentially. Therefore, when the lunch box goes around the feeding rack, the bottom of the lunch box can be sequentially clamped into the material clamping gap, and when the feeding rack rotates, the feeding push rod can push the side of the lunch box, thereby realizing the transportation of the lunch box and providing power for the lunch box to climb from low to high. At the same time, one material clamping gap is for one lunch box, so the transportation speed of the lunch box can be accurately controlled, and then its position can be accurately controlled to ensure the cutting quality of the cutting machine. The guide frame is used for flipping the lunch box and raising its position to realize flipping and transportation from bottom to top. Compared with the existing method of first conveying the lunch box to the top of the cutting machine and then conveying it downward to flip it, the present application only needs to convey the lunch box to the height of the cutting area of ​​the cutting machine, which greatly reduces energy consumption.

[0007] In the above-mentioned feeding and turning device, the feeding rack is located obliquely below the guide rack, and the top of the feeding rack is higher than the bottom of the guide rack, and the bottom of the feeding rack is lower than the bottom of the guide rack. When the lunch box goes around the feeding rack, it needs to pass between the feeding rack and the guide rack. The bottom of the guide rack guides the lunch box downward, so as to ensure that the lunch box can be stuck in the material-stuck gap first. The feeding rack generates sufficient driving force on the lunch box and ensures that the conveying position is more accurate.

[0008] In the above-mentioned feeding turning device, the feeding frame includes two feeding side plates respectively fixed at the two ends of the rotating shaft, and a plurality of feeding push rods are fixed between the two feeding side plates. An adjustment structure capable of adjusting the distance between two adjacent feeding push rods is provided between each feeding push rod and the feeding side plate. The feeding side plates improve the positioning of the feeding push rods, and the adjustment structure can adjust the width of the clamping gap, thereby being suitable for blister products of different sizes.

[0009] In the above-mentioned feeding turning device, the adjustment structure includes a strip hole opened on the feeding side plate along the radial direction of the rotating shaft of the feeding frame, the end of the feeding push rod passes through the strip hole and is locked and fixed by a nut, and a plurality of strip holes on the same feeding side plate are evenly distributed in the circumference, and the spacing between two adjacent strip holes gradually decreases from the outside to the inside along the radial direction. Loosen the nut to adjust the radial position of the feeding push rod, and ensure that all the feeding push rods are located on the same circumference, thereby adjusting the spacing between two adjacent feeding push rods and ensuring uniform material clamping gaps.

[0010] In the above-mentioned feeding turning device, the feeding side plate is provided with an observation notch between each adjacent two-line hole, so that the feeding side plate is in a polygonal star shape. By providing the observation notch, it is possible to observe whether the lunch box is properly inserted into the gap between the materials, and whether there is displacement or deviation during long-term working, so as to ensure the conveying quality.

[0011] In the above-mentioned feeding and turning device, the guide frame includes two guide side plates respectively fixed at both ends of the rotating shaft, and a plurality of guide support rods are fixed between the two guide side plates. The plurality of guide support rods are arranged parallel to the rotating shaft, and the plurality of guide support rods are evenly arranged around the rotating shaft of the guide frame. The plurality of guide support rods are on the same circumference, and provide stable support during the turning process of the lunch box, thereby ensuring the conveying accuracy.

[0012] In the above-mentioned feeding and turning device, a motor is fixed on the frame, the motor and the feeding frame are connected to each other through a pulley assembly 1, and the feeding frame and the guide frame are connected to each other through a pulley assembly 2. The feeding frame and the guide frame are driven to rotate by a motor to ensure synchronization between the two, so that the lunch boxes are transported in an orderly and accurate manner.

[0013] In the above-mentioned feeding and flipping device, the pulley assembly 1 includes a driving pulley 1 fixed to the output end of the motor, a driven pulley 1 fixed to one end of the rotating shaft of the feeding frame, and a belt 1, wherein a set of the belt is arranged on the driving pulley 1 and the driven pulley 1, and the pulley assembly 2 includes a driving pulley 2 fixed to the other end of the rotating shaft of the feeding frame, a driven pulley 2 fixed to one end of the rotating shaft of the guide frame, and a belt 2, wherein one end of the belt 2 is sleeved on the driving pulley 2, and the other end is twisted 180° and then sleeved on the driven pulley 2. Since the lunch box needs to be flipped, a reverse conveying process is required, that is, by twisting the belt 2 180°, the feeding frame and the guide frame are synchronously rotated in the opposite direction.

[0014] In the above-mentioned feeding and turning device, two motors are fixed on the frame, and the two motors are respectively connected to the two rotating shafts. The feeding frame and the guide frame are driven by their own motors, and can also ensure that the two rotate synchronously in opposite directions.

[0015] In the above-mentioned feeding turning device, the frame body includes two vertical rod bodies arranged vertically, the rotating shaft of the feeding frame is rotatably connected between the tops of the two vertical rod bodies, the tops of the two vertical rod bodies each have an inclined rod body inclined to one side, and the rotating shaft of the guide frame is rotatably connected between the tops of the two inclined rod bodies. The frame body is relatively light as a whole, and the inclined rod body can ensure both the height of the guide frame and the positional relationship between the guide frame and the feeding frame.

[0016] Compared with the prior art, the feeding and turning device has the following advantages:

[0017] 1. When the lunch box goes around the feeding rack, the bottom of the lunch box can be inserted into the material gap in turn. When the feeding rack rotates, the feeding push rod can push the side of the lunch box, thereby realizing the transportation of the lunch box and providing power for the lunch box to climb from low to high. At the same time, one material gap is for one lunch box, so the transportation speed of the lunch box can be accurately controlled, and then its position can be accurately controlled.

[0018] 2. Since the guide frame is used to flip the lunch box and raise its position, it can be flipped and transported from bottom to top. Compared with the existing method of first transporting the lunch box to the top of the cutting machine and then transporting it downward to flip it, the present application only needs to transport the lunch box to the height of the cutting area of ​​the cutting machine, which greatly reduces energy consumption.

[0019] 3. Since an adjustment structure capable of adjusting the distance between two adjacent feeding push rods is provided between each feeding push rod and the feeding side plate, the width of the clamping gap can be adjusted, thereby being suitable for blister products of different sizes.
