A feeding device for strip food packaging

Abstract

The present invention relates to a feeding device for packaging strip food. When the strip food is fed into the feeding hopper, the lifting beam can drive the rotating air pipe and the blowing head to extend into the feeding hopper, so that the blowing head can be lowered while blowing air downward to blow the strip food adhered to the feeding hopper downward, thereby preventing the food from adhering to the inner wall of the feeding hopper, allowing the food to be smoothly transported downward, and improving the yield rate of packaging; and when the feeding hopper needs to be cleaned, the lower ring part and the rotating air pipe are first locked by the clutch assembly so that it can rotate with the rotating air pipe, and then water is discharged through the water outlet pipe. Since the water outlet pipe is arranged on the lower ring part, it can rotate with the lower ring part, so that clean water is sprayed on each inner wall surface of the feeding hopper, and then the blowing head is used to blow air, so that the water is quickly dried and the residue adhered to the feeding hopper can be blown off, which saves time and labor and greatly improves the cleaning efficiency.

[0027] The following detailed description provides various embodiments or examples for implementing the present invention. Of course, these are merely examples or embodiments and are not intended to be limiting. Furthermore, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. Such repetition is for simplicity and clarity in describing the present invention and does not imply a specific relationship between the different embodiments and / or configurations discussed.

[0028] like Figures 1-9 The shown device is a strip food packaging feeding device, comprising a frame 1, on which several strip food hoppers 2 are spaced apart in the left and right directions, a lifting beam 3 that can be lifted up and down is provided on the frame 1, and several rotating air pipes 4 corresponding to the strip food hopper 2 are provided on the lifting beam 3, the rotating air pipe 4 is a vertical hollow structure, and the upper end is connected to an air pump through a rotating joint, and the lower end is connected to a blowing head 5 that can be extended into the strip food hopper 2, so that when the strip food is discharged from the strip food hopper 2, the lifting beam 3 can drive the rotating air pipe 4 and the blowing head 5 to extend into the strip food hopper 2, so that the blowing head 5 can blow air downward while descending, and the strip food stuck on the strip food hopper 2 can be blown down, thereby avoiding the food from adhering to the inner wall of the strip food hopper 2, allowing the food to be smoothly transported downward, achieving a stable feeding technical effect, and improving the packaging yield.

[0029] A water storage ring 6 is provided on the outer sleeve of the rotating air pipe 4. The water storage ring 6 includes an upper ring portion 7 and a lower ring portion 8 that rotates and covers the lower end of the upper ring portion 7. A water storage space 9 is formed inside the upper ring portion 7 and the lower ring portion 8. A water inlet pipe 10 is connected to the upper end of the upper ring portion 7. The water inlet pipe 10 is fixed to the lifting beam 3. A water outlet pipe 11 is provided at the lower end of the lower ring portion 8. A clutch assembly is provided between the lower ring portion 8 and the rotating air pipe 4. The clutch assembly is used to enable the lower ring portion 8 to rotate with the rotating air pipe 4, or to enable the lower ring portion 8 to be fixedly connected to the upper ring portion 7. Therefore, when it is necessary to clean the lower hopper 2, the lower ring part 8 is first locked with the rotating air pipe 4 through the clutch assembly so that it can rotate with the rotating air pipe 4, and then water is introduced into the water inlet pipe 10 and flows into the water storage space 9, and then the water is discharged through the water outlet pipe 11. Since the water outlet pipe 11 is arranged on the lower ring part 8, it can rotate with the lower ring part 8, so that the clean water is sprayed on each inner wall surface of the lower hopper 2, and then the air blowing head 5 is used to blow air to quickly dry the water and blow off the residue adhering to the lower hopper 2, saving time and effort and greatly improving the cleaning efficiency.

[0030] That is to say, when the lower hopper 2 needs to be cleaned, the lower ring part 8 can rotate together with the rotating air pipe 4 through the clutch assembly. When cleaning is not required, the lower ring part 8 is fixedly connected to the upper ring part 7 through the clutch assembly. At this time, the lower ring part 8 will not rotate with the rotating air pipe 4, reducing wear and improving service life.

[0031] See also Figure 4-Figure 8 As shown, the upper ring portion 7 includes an upper ring piece 21, and inner rings 22 extending downward are provided on both inner and outer sides of the upper ring piece 21. The lower ring portion 8 includes a lower ring piece 23, and outer rings 24 extending upward are provided on both inner and outer sides of the lower ring piece 23. The two outer rings 24 are rotatably sleeved on the two inner rings 22. Of course, in order to improve the sealing performance, a rotating seal is provided between the outer ring 24 and the inner ring 22.

[0032] Furthermore, the clutch assembly includes a cylindrical flange 31 provided on the rotating air pipe 4, the outer ring 24 on the inner side extends outward to form a collar 30, and the collar 30 is rotatably sleeved on the outside of the cylindrical flange 31, and a plurality of grooves 32 are provided on the outer wall of the cylindrical flange 31, and a spring 33 and a positioning steel ball 34 are provided in the groove 32, and a positioning groove 35 corresponding to the groove 32 is provided on the collar 30, and the positioning steel ball 34 is abutted against the positioning groove 35 under the action of the spring 33, and a push rod motor 36 is fixed on the upper ring piece 21, and the push rod of the push rod motor 36 is vertically upward and connected to a stop block 37, and a slot 38 is provided at the upper end of the collar 30, and the stop block 37 can be stuck in or out of the slot 38.

[0033] like Figure 4 As shown, the stop block 37 is inserted into the slot 38 at the upper end of the collar 30. At this time, the upper ring portion 7, the push rod motor 36, the stop block 37, the collar 30 and the lower ring portion 8 are fixed into a whole, so that the rotating air pipe 4 and the cylindrical flange 31 rotate in the innermost outer ring 24.

[0034] like Figure 5-7 As shown, the stop block 37 is driven upward by the push rod motor 36 and disengaged from the slot 38. At this time, under the action of the spring 33, the positioning steel ball 34 remains against the positioning slot 35, so that the lower ring portion 8 is connected to the cylindrical flange 31, thereby driving the lower ring portion 8 to rotate under the rotation of the rotating air pipe 4.

[0035] In the present invention, see Figure 4-Figure 7 As shown, a ball valve 41 is provided on the water inlet pipe 10 , and a transmission assembly is connected between the ball valve 41 and the stop block 37 , and the ball valve 41 is driven to open or close by the transmission assembly.

[0036] Furthermore, the ball valve 41 includes a switch valve stem 51, the transmission assembly includes a shift rod 52 provided on the stop block 37, a guide column 53 is provided on the shift rod 52, a guide groove 54 is provided on the switch valve stem 51, and the guide column 53 is movably provided in the guide groove 54.

[0037] like Figure 4 As shown, when the upper ring portion 7 is connected to the lower ring portion 8, that is, the upper ring portion 7 does not rotate, at this time, the ball valve 41 is in a closed state; and as shown Figure 7 As shown, the push rod motor 36 drives the stop block 37 to move upward and disengage from the slot 38, and the upper ring portion 7 disengages from the lower ring portion 8. While the stop block 37 moves upward, the lever 52 and the guide column 53 move upward together, and the guide column 53 moves in the guide groove 54 on the switch valve stem 51, thereby driving the switch valve stem 51 to swing upward, and then opening the ball valve 41, and clean water can enter the water storage space 9 and flow out from the outlet pipe 11.

[0038] See also Figure 9 As shown, a disc 81 is detachably mounted on the lower end of the blowing head 5 by means of bolts, and a number of cleaning cotton strips 82 are evenly distributed along the circumference of the outer side of the disc 81. In order to improve the cleaning effect, a disc 81 can be mounted on the lower end of the blowing head 5, and a cleaning cotton strip 82 is provided on the disc 81. When the blowing head 5 rotates, the disc 81 and the cleaning cotton strip 82 are driven to rotate, and the cleaning cotton strip 82 slaps the inner wall of the lower hopper 2 to knock off the residue on the lower hopper 2, thereby greatly improving the cleaning effect.

[0039] See also Figure 2 Figure 3 As shown, a first gear 61 is provided on each of the rotating air tubes 4, a rotating shaft 62 is rotatably installed on the lifting beam 3 and on two adjacent rotating air tubes 4, a second gear 63 is provided on each of the rotating shafts 62, and the second gear 63 can engage with the two adjacent first gears 61, a first pulley 64 is provided on one of the rotating shafts 62, a motor 65 is provided on one side of the lifting beam 3, a second pulley 66 is provided on the output shaft of the motor 65, and a toothed belt 67 is provided between the first pulley 64 and the second pulley 66.

[0040] The motor 65 drives the second pulley 66 to rotate, and under the action of the toothed belt 67 and the first pulley 64, drives the second gear 63 on the rotating shaft 62 to rotate. The second gear 63 and the first gear 61 rotate, thereby driving all the rotating air pipes 4 and the rotating shaft 62 to rotate.

[0041] In the present invention, a central air hole 71 connected to the rotating air pipe 4 is provided at the upper end of the blowing head 5, and a plurality of blowing holes 72 connected to the central air hole 71 are provided on the outer wall of the blowing head 5 at intervals along the circumference. The axial direction of the blowing hole 72 is tangent to the inner wall of the central air hole 71, and the blowing hole 72 is inclined and extends downward, so that when the blowing head 5 rotates following the rotating air pipe 4, the air flow blown out of the blowing hole 72 is spirally blown and directed downward, which can better blow off the strip food adhering to the inner wall of the lower hopper 2, so that the strip food can be discharged smoothly.

[0042] See also Figure 1 As shown, a lifting mechanism 92 for driving the lifting beam 3 to move up and down is further provided on the frame 1. The lifting mechanism 92 is of an existing conventional design and can only drive the lifting beam 3 to move up and down, so it will not be described in detail here.
