Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of pleating machine technology, and more specifically, to a double-wheel pleating machine for producing plastic sausage casings. Background Technology

[0002] The plastic casings for ham sausages are made of composite flexible packaging materials such as polyvinylidene chloride (PVDC), polyamide (PA, i.e., nylon), and ethylene-vinyl acetate copolymer resin (EVAL). They have the characteristics of high barrier properties, chemical resistance, and thermal stability. Among them, PVDC casings can withstand high-temperature cooking and have high gloss and transparency.

[0003] During the processing and filling of ham sausage plastic casings, in order to prevent the casings from bursting due to excessive expansion during filling, and to ensure more even filling and a neat product shape, pleating is usually required during the filling process. Existing pleating machines typically pleat the ham sausage plastic casings by rotating two pleating rollers. However, the distance between the two pleating rollers is relatively fixed, making it difficult to adapt to pleating different types of ham sausage plastic casings, resulting in low flexibility in use. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a double-wheel pleating machine for producing plastic sausage casings, which solves the technical problem that the distance between the two pleating wheels in the prior art is relatively fixed, making it difficult to adapt to the pleating of plastic sausage casings of different sizes and resulting in low flexibility of use.

[0005] According to one aspect, at least one embodiment of this disclosure provides a double-wheel pleating machine for producing plastic sausage casings, applied in a filling device. The filling device is provided with a filling tube and includes: pleating wheels, fixed wheels, and pleating plates. Two pleating wheels are provided, and the two pleating wheels are mounted on the filling device by a tensioning mechanism. The tensioning mechanism is used to adaptively adjust the distance between the two pleating wheels. Two fixed wheels are provided, and the two fixed wheels are mounted on the filling device by a moving mechanism. The moving mechanism is used to drive the two fixed wheels to move on the filling tube. Pleating plates are uniformly distributed and fixedly connected to the circumferential surfaces of the two pleating wheels.

[0006] To adjust the distance between the two pleating wheels, the tensioning mechanism includes: tension rods, support frames, and tension springs. There are two tension rods, one end of each tension rod is rotatably connected to one side of the filling equipment, and the other end of each tension rod is fixedly connected to the support frame. The two pleating wheels are rotatably connected to the top of the two support frames, and the two ends of the tension spring are fixedly connected to the two tension rods.

[0007] To support the movement of the fixed wheels and to fit the long sausage casing onto the filling tube, the moving mechanism includes: a moving frame, a rotating seat, a first motor, a transmission assembly, and a drive assembly. The moving frame is slidably connected to the filling equipment. There are two rotating seats, both of which are fixedly connected to the moving frame. The two fixed wheels are rotatably connected within the two rotating seats. There are two first motors, each mounted on one of the two rotating seats. The output ends of the two first motors pass through the two rotating seats and are fixedly connected to the two fixed wheels. The transmission assembly is located on one side of the filling equipment and is used to drive the moving frame to move. The drive assembly is located on one side of the filling equipment and is used to drive the transmission assembly to move.

[0008] To drive the moving frame to move, the transmission assembly includes a rotating gear and a screw. The rotating gear is rotatably connected to one side of the filling equipment, and one end of the screw is fixedly connected to one side of the rotating gear. The moving frame has a screw hole, and the screw is threaded into the screw hole.

[0009] To drive the rotating gear to rotate, the drive assembly includes: a motor frame, a drive gear, and a second motor. The motor frame is installed on one side of the filling equipment. The drive gear is rotatably disposed inside the motor frame and meshes with the rotating gear. The second motor is installed on the motor frame, and the output end of the second motor passes through the motor frame and is fixedly connected to the drive gear.

[0010] To increase the stability of the moving frame during sliding, multiple fixed blocks are fixedly connected to the filling equipment, and each of the fixed blocks is provided with a sliding groove, and the moving frame is slidably connected within the multiple sliding grooves.

[0011] To increase the stability of the tension rods during rotation, two connecting seats are fixedly connected to the filling equipment, and one end of each of the two tension rods is rotatably connected to the two connecting seats.

[0012] To improve the pleating effect, both pleating wheels have arc-shaped grooves on their circumferential surfaces, and the pleating plate is located within the arc-shaped grooves.

[0013] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, a moving mechanism is used to put the sausage casing onto the filling tube for filling. A stretching mechanism drives two pleating wheels to hold the sausage casing in place during filling. When the sausage casing moves, it is pleated by the two pleating wheels. The mechanism can adapt to different sizes of sausage casings and is highly flexible in use. Attached Figure Description

[0022] like Figures 1-4 The diagram illustrates a double-wheel pleating machine for producing plastic sausage casings according to an embodiment of this disclosure. It is applied to a filling device 1, which includes a filling tube 2. The machine comprises pleating wheels 3, fixed wheels 4, and pleating plates 5. Both pleating wheels 3 have arc-shaped grooves on their circumferential surfaces, and the pleating plates 5 are located within these grooves. Two pleating wheels 3 are mounted on the filling device 1 via a tensioning mechanism, which adjusts the spacing between them. Two fixed wheels 4 are mounted on the filling device 1 via a moving mechanism, which drives them to move on the filling tube 2. Pleating plates 5 are evenly distributed and fixedly connected to the circumferential surfaces of the two pleating wheels 3. The moving mechanism places the sausage casing onto the filling tube 2 for filling. The tensioning mechanism drives the two pleating wheels 3 to press against the casing during filling. As the casing moves, pleating occurs via the two pleating wheels 3. This machine is adaptable to different casing sizes and offers high flexibility.

[0023] The stretching mechanism includes: a stretching rod 6, a support frame 7, and a tension spring 8. Two connecting seats 18 are fixedly connected to the filling equipment 1. One end of each of the two stretching rods 6 is rotatably connected to the two connecting seats 18. There are two stretching rods 6. One end of each stretching rod 6 is rotatably connected to one side of the filling equipment 1. The other end of each stretching rod 6 is fixedly connected to the support frame 7. Two pleating wheels 3 are rotatably connected to the top of the two support frames 7. Both ends of the tension spring 8 are fixedly connected to the two stretching rods 6. The tension spring 8 stretches and rebounds the two stretching rods 6, so that when the two pleating wheels 3 come into contact with the casings during filling, the two pleating wheels 3 can adapt to casings of different specifications and pleat the casings during filling.

[0024] The moving mechanism includes: a moving frame 9, a rotating seat 10, a first motor 11, a transmission assembly, and a drive assembly. Multiple fixed blocks 17 are fixedly connected to the filling equipment 1, each with a groove. The moving frame 9 is slidably connected within these grooves and to the filling equipment 1. Two rotating seats 10 are provided, each fixedly connected to the moving frame 9. Two fixed wheels 4 are rotatably connected to the two rotating seats 10. Two first motors 11 are provided, each mounted on one of the two rotating seats 10. The output ends of the two first motors 11 pass through the two rotating seats 10 and are fixedly connected to the two fixed wheels 4. The transmission assembly is located on one side of the filling equipment 1 and is used to move the moving frame 9. The drive assembly is located on one side of the filling equipment 1 and is used to drive the transmission assembly. The transmission assembly includes: a rotating gear 12 and a screw 13. The rotating gear 12 is rotatably connected to one side of the filling equipment 1, and the screw 13... The end is fixedly connected to one side of the rotating gear 12. The movable frame 9 has a screw hole, and the screw 13 is threaded into the screw hole. The drive assembly includes: a motor frame 14, a drive gear 15, and a second motor 16. The motor frame 14 is installed on one side of the filling equipment 1. The drive gear 15 is rotatably set in the motor frame 14 and meshes with the rotating gear 12. The second motor 16 is installed on the motor frame 14. The output end of the second motor 16 passes through the motor frame 14 and is fixedly connected to the drive gear 15. The second motor 16 drives the drive gear 15 to rotate. When the drive gear 15 rotates, it drives the rotating gear 12 to rotate. When the rotating gear 12 rotates, it drives the screw 13 to rotate, thereby causing the screw 13 to rotate in the screw hole. This drives the movable frame 9 to move on the filling equipment 1, thereby driving the two fixed wheels 4 to move on the filling tube 2. The first motor 11 installed on the rotating seat 10 drives the fixed wheels 4 to rotate, thereby putting the casing on the filling tube 2.

[0025] The working principle is as follows: When it is necessary to pleat the sausage casing after filling, the sausage casing is put on the filling tube 2. The second motor 16 drives the drive gear 15 to rotate. When the drive gear 15 rotates, it drives the rotating gear 12 to rotate. When the rotating gear 12 rotates, it drives the screw 13 to rotate, so that the screw 13 rotates in the screw hole. This drives the moving frame 9 to move on the filling equipment 1, which in turn drives the two fixed wheels 4 to move on the filling tube 2. The first motor 11 installed on the rotating seat 10 drives the fixed wheels 4 to rotate, so that the sausage casing is put on the filling tube 2. Then, the filling equipment 1 fills the sausage casing. During the filling process, the sausage casing is located between the two pleating wheels 3. The tension spring 8 stretches and rebounds the two tension rods 6. So when the two pleating wheels 3 come into contact with the sausage casing during filling, the two pleating wheels 3 can adapt to different specifications of sausage casing and pleat the sausage casing during filling.
