[0054] An embodiment of the present application provides a reverse thrust device, comprising a first substrate, a second substrate and a push plate. A slide groove is provided on the surface of the first substrate; the second substrate is movably connected to the first substrate along a first direction.

[0055] The push plate moves under the guidance of the slide slot, can extend obliquely and then abut against the packaging box to push the packaging box; the structure is simple and reliable, and the stability is high.

[0056] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0057] like Figure 1 and Figure 2As shown, the embodiment of the present application provides a heat shrink wrapping device 100, which can be used for heat shrink packaging packaging boxes, including a base 4, a conveyor belt 2, a reverse thrust device 1 and a corner cutting device 3. The conveyor belt 2 is rotatably arranged on the base 4, and can carry the film box 200 and transport the film box 200 along the first direction X. The corner cutting device 3 is arranged on the base 4 and located at the end of the conveyor belt 2, and is used to cut the packaging film of the film box 200 on the conveyor belt 2. The reverse thrust device 1 is arranged on the base 4 and located on the side of the conveyor belt 2. The reverse thrust device 1 is adjacent to the corner cutting device 3, and can push the packaging box in the direction of the film box 200 being cut toward the corner cutting device 3, so that the gap between the packaging box and the bottom of the packaging film is reduced to improve the aesthetics after the corner cutting.

[0058] In some embodiments, there are two groups of conveyor belts 2, and the two groups of conveyor belts 2 are spaced apart along a second direction Y perpendicular to the first direction X. When the film-wrapped box 200 is on the conveyor belt 2, the two groups of conveyor belts 2 are respectively in contact with the two ends of the bottom of the film-wrapped box 200 to stably carry and transport the film-wrapped box 200.

[0059] In some embodiments, there are two sets of reverse thrust devices 1, which are respectively arranged on opposite sides of the two sets of conveyor belts 2. The two sets of reverse thrust devices 1 can act on the same film box 200 at the same time, and respectively abut against the two ends of the film box 200 to abut and push the film box 200 steadily to prevent the film box 200 from being pushed crooked.

[0060] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the reverse thrust device 1 includes a first base plate 11 , a second base plate 12 , a thrust plate 13 and a driving source 14 .

[0061] The first substrate 11 is disposed on the base 4, and the inner side of the first substrate 11 is close to the conveyor belt 2. A slide groove 111 is disposed on the upper surface of the first substrate 11, and the slide groove 111 includes a first groove section 111a and a second groove section 111b that are connected to each other. The first groove section 111a is disposed on the edge of the first substrate 11 close to the conveyor belt 2, and the first groove section 111a extends along the first direction X. The second groove section 111b is connected to the end of the first groove section 111a away from the angle cutting device 3, and the second groove section 111b extends along a third direction Z inclined to the first direction X, and the second groove section 111b extends in a direction away from the conveyor belt 2.

[0062] In the present application, the inner side of the first substrate 11 refers to the side of the first substrate 11 close to the conveyor belt 2 .

[0063] The second substrate 12 is movably connected to the first substrate 11 along the first direction X. In some embodiments, the reverse thrust device 1 further includes a first slide rail 15 and a first slider 16 connected to each other, and the extension direction of the first slide rail 15 is parallel to the first direction X. One of the first slide rail 15 and the first slider 16 is disposed on the first substrate 11, and the other of the first slide rail 15 and the first slider 16 is disposed on the second substrate 12, so that the second substrate 12 can move accurately relative to the first substrate 11 along the first direction X. In some embodiments, the first slide rail 15 is fixedly disposed on the first substrate 11, and the first slider 16 is fixedly disposed on the second substrate 12.

[0064] It can be understood that the extension direction of the first slot section 111a is parallel to the extension direction of the first slide rail 15, and the first slot section 111a is spaced apart from the first slide rail 15. The first slide rail 15 is arranged on the side of the slide groove 111 away from the conveyor belt 2, and along the first direction X, the second slot section 111b is extended from the end of the first slot section 111a to the direction close to the first slide rail 15.

[0065] The push plate 13 is movably connected to the second substrate 12 along the second direction Y. In some embodiments, the reverse thrust device 1 further includes a second slide rail 17 and a second slider 18 connected to each other, and the extension direction of the second slide rail 17 is parallel to the second direction Y. One of the second slide rail 17 and the second slider 18 is arranged on the second substrate 12, and the other of the second slide rail 17 and the second slider 18 is arranged on the push plate 13, so that the push plate 13 can accurately move along the second direction Y relative to the second substrate 12. In some embodiments, the second slide rail 17 is fixedly arranged on the push plate 13, and the second slider 18 is fixedly arranged on the second substrate 12. When the second substrate 12 moves relative to the first substrate 11, the second substrate 12 drives the push plate 13 to move together.

[0066] The end of the push plate 13 is arranged in the slide groove 111, and can move under the guidance of the slide groove 111. In some embodiments, the reverse thrust device 1 further includes a pulley 19, which is rotatably arranged at the end of the push plate 13. The pulley 19 is arranged in the slide groove 111, and the outer circumferential surface of the pulley 19 abuts against the side wall of the slide groove 111. When the push plate 13 moves along the first direction X driven by the second substrate 12, the side wall of the slide groove 111 applies a reaction force to the pulley 19 so that the push plate 13 moves along the second direction Y relative to the second substrate 12, and at the same time, the push plate 13 moves along the direction of the slide groove 111 relative to the first substrate 11.

[0067] The driving source 14 is fixedly disposed on the first substrate 11 . The driving source 14 is connected to the second substrate 12 and can drive the second substrate 12 to move along the first direction X.

[0068] In some embodiments, the driving source 14 includes a pneumatic cylinder, a hydraulic cylinder, an electric push rod 141 or a driving motor.

[0069] When the driving source 14 includes a cylinder, a hydraulic cylinder or an electric push rod 141, the output end of the driving source 14 has a push rod 141, and the driving source 14 can drive the push rod 141 to telescopically move. The end of the push rod 141 is connected to the second base 4 to drive the second base 4 to move.

[0070] When the driving source 14 includes a driving motor, the reverse thrust device 1 also includes a transmission mechanism (not shown), which connects the driving motor and the second push rod 141. The driving motor is driven by the transmission mechanism, so that the transmission mechanism drives the second push rod 141 to move.

[0071] The transmission mechanism further includes a driving wheel, a reversing wheel and a transmission member, the driving wheel and the reversing wheel are rotatably connected to the first base body 4, the central axes of the driving wheel and the reversing wheel are perpendicular to the first direction X, and the central connecting line of the driving wheel and the reversing wheel is parallel to the first direction X. The transmission member connects the driving wheel and the reversing wheel, and the part of the transmission member located between the driving wheel and the reversing wheel is connected to the second base plate 12. The driving motor is connected to the driving wheel and can drive the driving wheel to rotate, the rotation of the driving wheel pulls the transmission member to move along the first direction X, and the transmission member drives the second base plate 12 to move together.

[0072] In some embodiments, the driving wheel and the reversing wheel are sprocket wheels, and the transmission member is a chain. In some embodiments, the driving wheel and the reversing wheel are synchronous wheels, and the transmission member is a synchronous belt.

[0073] The following is a further explanation by taking the example that the driving source 14 includes a cylinder.

[0074] The cylinder is fixedly mounted on the first substrate 11, and a push rod 141 is disposed on the cylinder. The push rod 141 can perform telescopic movement relative to the cylinder. The push rod 141 is extended along the first direction X, and the end of the push rod 141 is connected to the second push rod 141, so that the cylinder drives the second push rod 141 to move along the first direction X by driving the push rod 141 to move.

[0075] In some embodiments, the cylinder is disposed on a side of the second substrate 12 close to the corner cutting device 3. When the cylinder drives the push rod 141 to extend, the push rod 141 drives the second substrate 12 to move away from the corner cutting device 3, that is, to move away from the first slot section 111a. When the cylinder drives the push rod 141 to retract, the push rod 141 drives the second substrate 12 to move closer to the corner cutting device 3, that is, to move closer to the first slot section 111a.

[0076] When the pulley 19 is located at the end of the second groove section 111b close to the first slide rail 15, that is, the pulley 19 is located in the slide groove 111 away from the inner side of the first substrate 11, and the push plate 13 is located away from the inner side of the first substrate 11. This is the initial state of the reverse thrust device 1. At this time, the film box 200 can be transferred under the support of the conveyor belt 2 without touching the push plate 13.

[0077] When the cylinder drives the push rod 141 to retract, the push rod 141 drives the second substrate 12 to move closer to the corner cutting device 3, that is, to move closer to the first slot section 111a. Under the guidance of the second slot section 111b, the push plate 13 moves closer to the corner cutting device 3 along the third direction Z, that is, to move closer to the first slot section 111a. When the pulley 19 moves to the first slot section 111a, the push plate 13 starts to move along the first direction X. At this time, if the conveyor belt 2 in front of the push plate 13 carries a film box 200, the speed of the cylinder driving the push rod 141 to retract is greater than the moving speed of the conveyor belt 2, and the push plate 13 can abut against the packaging box, and the packaging film cannot be displaced under the friction of the conveyor belt 2, so that the packaging box moves relative to the packaging film toward the direction close to the corner cutting device 3. Because the bag opening of the packaging film is usually facing opposite to the moving direction of the conveyor belt 2, the push plate 13 pushes the packaging box close to the bottom of the packaging film, thereby reducing the gap between the packaging box and the bottom of the packaging film, which can improve the aesthetics after cutting.

[0078] The above-mentioned heat shrink film packaging device 100 transfers the film-wrapped box 200 through the conveyor belt 2. The reverse push device 1 pushes the packaging box to reduce the distance between the packaging box and the bottom of the packaging film, thereby improving the aesthetics after the corner cutting. By arranging a pulley 19 at the end of the push plate 13, the pulley 19 abuts against the side wall of the slide groove 111, thereby reducing the wear of parts and extending the service life of parts. The heat shrink film packaging device 100 has a simple and reliable structure and high stability.

[0079] In addition, those skilled in the art may also make other changes within the spirit of the present application. Of course, these changes made according to the spirit of the present application should be included in the scope disclosed in the present application.
