Description

Technical Field

[0001] The utility model belongs to the field of packaging, and in particular relates to a box sealing device for a plant block product. Background Art

[0002] The carton sealing machine can seal cartons quickly and efficiently, reducing manpower requirements, thereby reducing labor costs and avoiding problems such as loose or uneven tape adhesion that may occur in manual carton sealing.

[0003] According to a carton sealing machine disclosed in the Chinese patent authorization announcement number CN216128525U, the carton to be sealed is placed on a roller line, and is transported between an upper carton sealing mechanism and a lower carton sealing mechanism through the transmission of the roller line. The upper and lower ends of the carton body are sealed by the cooperation of the upper and lower carton sealing mechanisms; the width adjustment mechanism on the equipment frame is rotated by turning the hand wheel, thereby driving the side belt line to move to both sides or the middle to clamp the carton body. However, the belt rubs against the carton for a long time, and the tension between the belt and the rotating roller will decrease over time, thereby reducing the transportation efficiency of the carton. In addition, when sealing the carton, only the two bending seams of the carton are sealed with tape. During transportation, the tape is easily torn, causing the sealing of the carton to crack.

Example 2

[0054] This embodiment makes the following improvements on the basis of the first embodiment: Figure 1 、 Figure 2 and Figure 6 As shown, the pushing structure includes a base 23 and a second rotating motor 24. The base 23 is rectangular and its two adjacent side surfaces are fixedly connected to the ends of the first conveying support frame 1 and the second conveying support frame 2 respectively. Support platforms 25 are fixedly connected to the four corners of the upper surface of the base 23. Two rollers 26 are rotatably connected between the two support platforms 25 close to the first conveying support frame 1. The two rollers 26 are covered with the same second conveyor belt 27.

[0055] The second rotary motor 24 is installed on one side of a support platform 25 rotatably connected to a roller 26. The end of one of the rollers 26 slides through the support platform 25 and is fixedly connected to the rotating shaft of the second rotary motor 24. The rotating shaft on the second rotary motor 24 drives the roller 26 to rotate, thereby driving the second conveyor belt 27 to start moving. When the first conveyor belt 11 pushes the carton 5 to the support platform 25, the bottom of the carton 5 contacts the second conveyor belt 27. After the first conveyor belt 11 separates from the carton 5, the carton 5 can continue to be driven to move by the second conveyor belt 27.

[0056] Furthermore, the pushing structure also includes a carton support plate 28 and a push plate 29. The upper surfaces of the multiple support platforms 25 are fixedly connected to the same carton support plate 28. A side of the carton support plate 28 close to the first conveying support frame 1 is provided with an avoidance groove 30, and the second conveyor belt 27 is located in the avoidance groove 30.

[0057] Two sets of slide grooves 31 are provided on the carton support plate 28. The bottom of the carton support plate 28 is slidably connected to a sliding tooth plate 32 corresponding to the slide grooves 31. The upper surface of the two sets of sliding tooth plates 32 is provided with an insertion rod 33 on the same side. The two sets of insertion rods 33 slide through the slide grooves 31 and the ends are plugged with the same push plate 29.

[0058] Further, such as Figure 6 and Figure 7 As shown, the same side of the two sets of sliding tooth plates 32 are slidably connected to a limit plate 34, the limit plate 34 is U-shaped and the upper surface is fixedly connected to the bottom of the carton support plate 28, and the side of the sliding tooth plate 32 close to the limit plate 34 is fixedly connected to a slide rod 35, and the free end of the slide rod 35 slides through the limit plate 34 and extends outside the limit plate 34;

[0059] A return spring 37 is sleeved on the slide rod 35 , and two ends of the return spring 37 are respectively in contact with the sliding tooth plate 32 and the limit plate 34 .

[0060] Furthermore, a plurality of shaft support blocks 38 are provided at the bottom of the carton support plate 28. The plurality of shaft support blocks 38 are rotatably connected to the same rotating shaft 39. The rotating shaft 39 is fixedly connected to a half-tooth gear 40 meshing with the sliding tooth plate 32.

[0061] A third rotary motor 41 is provided on the base 23 , and a rotary shaft of the third rotary motor 41 is fixedly connected to the rotary shaft 39 ;

[0062] Furthermore, a guide portion 42 is provided at one end of one of the protective outer frames 9 on the second conveying support frame 2. The guide portion 42 is located directly above the carton support plate 28 and away from the side of the first conveying support frame 1. The guide portion 42 is hollow inside and is rotatably connected to a plurality of rollers 43 to reduce the friction between the carton 5 and the guide portion 42 when moving.

[0063] Furthermore, a control unit 44 is provided on one end of the guide portion 42 away from the protective outer frame 9, and a push-type starter 36 is provided on the side of the control unit 44 close to the first conveying support frame 1. The push-type starter 36 is electrically connected to the third rotating motor 41;

[0064] Specifically, the second conveyor belt 27 pushes the carton 5 to move, so that the carton 5 contacts the push plate 29. At this time, the push-type starter 36 is in a pressed state and controls the third rotary motor 41 to be in a working state. The third rotary motor 41 drives the rotating shaft 39 to rotate clockwise through the rotating shaft. The half-tooth gear 40 continues to rotate clockwise with the rotating shaft 39. Through the meshing action, the sliding tooth plate 32 drives the push plate 29 to slide along the direction of the second conveying support frame 2 through the insertion rod 33, pushing the carton 5 out. During the sliding process, the sliding tooth plate 32 pushes the slide bar 35 out of the limit plate 34, and the reset spring 37 is in a compressed state, and the limit plate 34 pushes the carton 5 to between the first conveyor belt 11 on the second conveying support frame 2. At this time, the carton 5 stops pressing the push-type starter 36, and the third rotating motor 41 stops working. The return spring 37 in a compressed state begins to stretch and reset, and pushes the sliding tooth plate 32 and the push plate 29 to reset. The carton 5 moves through the first conveyor belt 11 on the second conveying support frame 2, and the top and bottom of the carton 5 are longitudinally fitted and packaged by the upper longitudinal tape applicator 7 and the lower longitudinal tape applicator 46, thereby further strengthening the packaging strength of the carton 5.

[0065] In summary, the workflow of this utility model is as follows:

[0066] Before use, place the loaded cartons 5 between the two adjustable conveyor rails 8. By rotating the second thread adjustment handle 22, the positive and negative threads on the second thread adjustment handle 22 will drive the two connecting plates 21 to move toward or away from each other. Then, the spacing between the adjustable conveyor rails 8 can be adjusted according to the size of the cartons 5, so that the first conveyor belt 11 is in contact with the cartons 5.

[0067] The first rotary motor 13 and the second rotary motor 24 are turned on. The first rotary motor 13 drives the third rotating roller 10 to rotate, and the first conveyor belt 11 starts to move, thereby driving the carton 5 to move along the direction of the pushing structure. The upper transverse tape applicator 6 and the lower transverse tape applicator 45 apply transverse tape to the top and bottom of the carton 5 for sealing.

[0068] The rotating shaft on the second rotating motor 24 drives the roller 26 to rotate, thereby driving the second conveyor belt 27 to start moving. When the first conveyor belt 11 pushes the carton 5 to the support platform 25, the bottom of the carton 5 contacts the second conveyor belt 27. After the first conveyor belt 11 separates from the carton 5, the carton 5 is driven by the second conveyor belt 27 to move along the direction of the pushing structure.

[0069] When the carton 5 contacts the push plate 29, the push-type starter 36 is in a pressed state and controls the third rotary motor 41 to be in a working state. The third rotary motor 41 drives the rotating shaft 39 to rotate clockwise through the rotating shaft. The half-tooth gear 40 continues to rotate clockwise with the rotating shaft 39. Through the meshing action, the sliding tooth plate 32 drives the push plate 29 to slide along the direction of the second conveying support frame 2 through the insertion rod 33, pushing the carton 5 out. During the sliding process, the sliding tooth plate 32 pushes the slide bar 35 out of the limit plate 34, and the reset spring 37 In the compressed state, the limit plate 34 pushes the carton 5 to between the first conveyor belt 11 on the second conveying support frame 2. At this time, the carton 5 stops pressing the push-type starter 36, and the third rotating motor 41 stops working. The return spring 37 in the compressed state begins to stretch and reset, and pushes the sliding tooth plate 32 and the push plate 29 to reset. The carton 5 moves through the first conveyor belt 11 on the second conveying support frame 2, and the top and bottom of the carton 5 are longitudinally fitted and packaged by the upper longitudinal tape applicator 7 and the lower longitudinal tape applicator 46.

[0070] However, as is well known to those skilled in the art, the working principles and wiring methods of the upper transverse tape applying machine 6, the upper longitudinal tape applying machine 7, the lower transverse tape applying machine 45, the lower longitudinal tape applying machine 46, the first rotating motor 13, the second rotating motor 24, the push-type starter and stopper 36 and the third rotating motor 41 are commonplace and are conventional means or common knowledge, so they will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.
