The detection switches 20 correspond to the chute one by one and are used to detect whether there are plastic rods in the corresponding chute. A horizontally arranged angle iron baffle plate 23 is hoisted at one end of the conveyor mechanism 7 at its outlet through a baffle cylinder 22. After the baffle cylinder 22 extends, the baffle plate 23 blocks the front end of the plurality of pairs of baffle plates 15, so as to realize the unified release of the plastic rods that have arrived at the outlet of the conveyor mechanism 7 after they are gathered.

[0037] A clamping rack 19 is fixed on the frame 14 of the conveyor mechanism 7 near the detection switch 20, and a plurality of pneumatic fingers 42 are evenly suspended in the clamping rack 19. The pneumatic fingers 42 correspond to the slide grooves one by one, and L-shaped clamping arms 41 are symmetrically connected to the lower ends of the pneumatic fingers 42. The lower ends of the clamping arms 41 are inserted into the corresponding slide grooves through the grooves provided at the bottom of the baffle plate 15, and are used to clamp the previous plastic rod detected by the detection switch 20, so as to ensure that a group of plastic rods falls each time.

[0038] The two ends of the strip 21 are fixed in the material clamping frame 19 by screws, and the baffle cylinder 22 is fixed to the front end of the material clamping frame 19 by a vertically arranged cylinder seat plate 52. A driving motor 37 is provided on one side of the conveyor belt mechanism 7 for driving the conveyor belt mechanism to operate.

[0039] A silo 5 is provided on one side of the entrance of the conveyor mechanism. The silo 5 is mounted on a bracket 3 through two linear vibrators 4 and arranged along the longitudinal direction of the conveyor mechanism for adding plastic rods to be inserted. The front end of the silo 5 is open, and the bottom plate 6 of the silo 5 is longer than the side plate of the silo 5 and close to the entrance of the conveyor mechanism. A plurality of transverse slideways 601 are evenly distributed on the bottom plate 6 of the silo 5. The transverse slideways 601 correspond to the slide grooves one by one, and are used to sequentially guide the plastic rods added to the silo 5 into the conveyor mechanism.

[0040] An arc-shaped slide plate 10 is fixed between adjacent transverse slideways on the bottom plate 6 in the silo body at the rear of the silo 5, and three material-dispensing plate brush rollers 11 are installed in parallel in the upper part of the silo 5, which are used to move the plastic rods added into the silo 5 so that the plastic rods do not pile up and quickly slide into the transverse slideway through the arc-shaped slide plate 10. The two ends of the roller shaft of the material-dispensing plate brush roller 11 pass through the silo 5 and are installed on the plate brush support 12 located on both sides of the silo 5 through bearings.

[0041] The rod insertion mechanism 8 includes two vertical plates 30 fixed on the front side of the mounting plate frame 1, and a slide plate and a limiting bottom plate 31 are arranged up and down by screws between the two vertical plates 30 and below the outlet of the conveyor belt mechanism. The slide plate is divided into an upper slide plate 44 and a lower slide plate 47 arranged vertically up and down, and a plurality of longitudinal slides 45 are evenly distributed on the upper and lower slide plates, respectively. The longitudinal slides 45 are rectangular, and the longitudinal slides 45 on the upper and lower slide plates correspond to each other one by one and are relatively deflected by 90 degrees. Rectangular spring tubes 46 are respectively sandwiched between the corresponding longitudinal slides 45 on the upper and lower slide plates. The upper and lower parts of the spring tubes 46 are deflected 90 degrees, and are used to rotate the plastic rod entering the slide plate 90 degrees and drop it into the pushing groove 481.

[0042] A guide plate is fixed on the upper slide plate 44 corresponding to one side of the conveyor belt mechanism, and a pair of guide pieces 43 are welded on the inner side of the inclined surface of the upper portion of the guide plate corresponding to each longitudinal slide 45 of the upper slide plate 44. Each pair of guide pieces 43 is symmetrically arranged in a wedge shape and the upper opening is larger than the lower opening width. The upper opening of each pair of guide pieces 43 is close to the bottom of the outlet of the conveyor belt mechanism, and is used to guide the plastic rods conveyed by the conveyor belt mechanism into the corresponding longitudinal slide. A transparent back plate 53 is fixed on the other side of the guide plate on the upper slide plate 44. The upper end of the transparent back plate 53 is higher than the upper slide plate 44, and is used to cooperate with the guide piece 43 for guiding, and at the same time, it is convenient to check the unloading situation in the longitudinal slide.

[0043] The lower slide plate 47 is formed by two flat plates that are attached to each other, and the longitudinal slide on the lower slide plate 47 is composed of rectangular grooves respectively arranged on the opposite surfaces of the two flat plates, so as to facilitate the processing and fixing of the spring tube 46. The inner plate of the two flat plates is an aluminum plate, and the outer plate is a tempered glass plate, so as to facilitate the inspection of the material discharge in the longitudinal slide.

[0044] The limiting bottom plate 31 is arranged horizontally, and a push cylinder 40 is fixed on the limiting bottom plate 31 through a cylinder seat 49, and a push plate 48 is connected through the push cylinder 40. The push plate 48 is located below the lower slide plate 47, and two groups of guide components 51 composed of guide pillars and guide sleeves are symmetrically arranged between the push plate 48 and the cylinder seat 49. A plurality of push grooves 481 corresponding to the longitudinal slides are evenly distributed on the push plate 48, which are used to push the plastic rods that slide down the slide plate to the rod insertion position. A limiting block 32 is respectively arranged on both sides of the push groove 481 in front of the push plate 48 to block the plastic rods that enter the push groove 481 and prevent the plastic rods from falling forward.

[0045] An upper connecting plate 24 and a lower connecting plate 26 arranged horizontally are fixed between the two vertical plates 30 and located in front of the slide plate. An auxiliary cylinder 33 is fixed on the lower connecting plate 26. An auxiliary plugging plate 27 connected to the cylinder rod of the auxiliary cylinder 33 is provided below the lower connecting plate 26. Two groups of guide pillars 34 and guide sleeves are symmetrically provided between the auxiliary plugging plate 27 and the lower connecting plate 26 to realize the horizontal lifting and lowering of the auxiliary plugging plate 27. Multiple feed tubes 28 corresponding to the feed grooves 481 are evenly inserted on the auxiliary plugging plate 27 near the side of the feed pushing plate 48. The outer edge of the feed tube 28 is an arc-shaped flat tube, which is used to guide the plastic rod into the corresponding packaging material bottle cavity.

[0046] A rod inserting cylinder 25 is fixed in the middle between the upper and lower connecting plates. The rod inserting cylinder 25 is a rodless cylinder. A push rod frame 36 is fixed on the slider of the rod inserting cylinder 25, and a plurality of vertically arranged rod inserting push rods 35 are evenly connected to the push rod frame 36. The lower ends of the rod inserting push rods 35 pass through the lower connecting plate 26 and correspond one by one to the central holes of the feed tube 28, so as to push the plastic rod pushed to the rod inserting position into the corresponding packaging material bottle cavity through the feed tube 28.

[0047] A guide sleeve 38 is fixed to the bottom surface of the lower connecting plate 26 at a through hole corresponding to each plunger 35 , for accurately guiding the plunger 35 into the corresponding feed tube 28 .

[0048] Two clamping cylinders 50 are fixed under the limiting bottom plate 31 and arranged in an up-and-down manner. Clamping frames 29 are respectively connected to the front ends of the cylinder rods of the two clamping cylinders 50. A plurality of U-shaped grooves are evenly distributed at the opposite ends of the two clamping frames 29 for mutually cooperating to clamp the packaging materials to be inserted into the plastic rod. The packaging materials of the cheese canning machine pass through the two clamping frames 29.

[0049] During operation, the plate brush motor 9, the linear vibrator 4 and the driving motor 37 of the conveyor belt mechanism are started, and the plastic rods are added into the hopper 5 from above. The hopper 5 vibrates back and forth under the action of the linear vibrator 4, and the plastic rods are quickly slid into the transverse slide through the arc-shaped slide plate 10 under the action of the brush roller 11 of the material shifting plate, and enter the chute of the conveyor belt mechanism in turn as the hopper 5 vibrates back and forth; the plastic rods entering each chute are transported forward with the operation of the conveyor belt, and when the plastic rods move under the detection switch 20, the detection switch 20 transmits a signal to the controller, and the controller controls the pneumatic finger 42 to move, clamping the previous plastic rod detected by the detection switch 20, and at the same time, the baffle cylinder 22 extends to block the detected plastic rod through the baffle 23. When all the detection switches 20 detect the plastic rods, the baffle cylinder 22 retracts, so that a group of plastic rods that have arrived at the exit of the conveyor belt mechanism are gathered together and fall together; after falling, the pneumatic fingers 42 reset to release the clamped plastic rods, and the baffle cylinder 22 immediately extends, driving the baffle to repeatedly block the exit of the conveyor belt mechanism, ready to release the next group of plastic rods.

[0050] After each group of plastic rods drops from the conveyor belt mechanism, they pass through multiple pairs of guide plates 43 on the guide plate and enter the longitudinal slide of the upper slide plate 44, and then enter the spring tube 46. Since the upper and lower parts of the spring tube 46 are deflected 90 degrees, the plastic rods in the spring tube 46 will rotate 90 degrees, and then fall into the pushing groove 481 through the longitudinal slide of the lower slide plate 47. At the same time, the two clamping cylinders 50 are started, driving the two clamping frames 29 to move relative to each other, clamping the packaging material of the cheese canning machine; the auxiliary cylinder 33 is started and extended, driving the auxiliary rod insertion plate 27 to move downward to a position flush with the limiting bottom plate 31, and driving the discharge tube 28 to be inserted into the corresponding packaging material bottle cavity; finally, the pushing cylinder 40 is started, driving the pushing plate 48 to move forward, so that the pushing groove 481 moves to the position corresponding to the discharge tube 28; the rod inserting cylinder 25 is started, driving multiple rod inserting push rods 35 to move downward at the same time, and the plastic rods in the pushing groove 481 are simultaneously inserted through the discharge tube 28 into the corresponding packaging material bottle cavity, such as Fig.10 As shown, the rod insertion is completed.

[0051] After the rod is inserted, the rod inserting cylinder 25, the material pushing cylinder 40, the auxiliary cylinder 33 and the clamping cylinder 50 are reset in sequence to prepare for the next rod insertion.
