Description

Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a stable box conveying device for an automatic box opener. Background Art

[0002] At present, the automatic carton opener is a commonly used automatic carton opener for product outer packaging. The existing automatic carton openers basically adopt the form of inclined silos. The cartons slide down along the inclined silo slideway under their own gravity. There are the following problems:

[0003] 1. Under the influence of external shocks such as vibration and friction, as well as internal factors such as the rough surface of the carton and the large friction between the slideway, the carton is easily stuck in the silo and cannot be transported forward, and the carton cannot be opened. Therefore, it is necessary to solve the problem of how to stably transport the carton in the silo of the automatic carton opener;

[0004] 2. Due to vibration during the operation of the equipment, the carton is prone to tilt when it is opened and pushed forward, resulting in the problem that the carton cannot be output to the subsequent workstation in a square and stable manner. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defect of jamming of box feeding in the existing automatic box opening machine and to provide a stable box feeding device for the automatic box opening machine.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] The stable box conveying device of the automatic carton opener is characterized in that it is arranged along the extension direction of the silo slide rail, and includes a box pushing mechanism and a limiting mechanism. The box pushing mechanism includes a power mechanism, a transmission chain and a carton pushing plate. The power mechanism is connected to the carton pushing plate through the transmission chain. The limiting mechanism is located above the end of the transmission chain and is installed on one side of the silo slide rail.

[0008] The carton is placed on the power mechanism and the transmission chain, the carton push plate moves to drive the carton to move forward smoothly, and the limiting mechanism limits the carton to ensure that the carton is output to the subsequent workstation in a square and stable manner.

[0009] Furthermore, the power mechanism includes a carton detection switch and a carton conveying power cylinder. The carton detection switch controls the action of the carton conveying power cylinder by sending an action signal. The carton detection switch detects whether there is a carton and gives an action signal to the carton conveying power cylinder to achieve intermittent power output. After receiving the action signal, the carton conveying power cylinder performs a reciprocating action to provide power for the transportation of the carton.

[0010] Furthermore, the power mechanism further comprises a one-way bearing, which is connected to the box-transporting power cylinder. The one-way bearing cooperates with the reciprocating motion of the box-transporting power cylinder to convert the reciprocating motion into a one-way forward power output.

[0011] Furthermore, a connecting frame and a swinging member are provided at the output end of the transport box power cylinder. A hinge shaft perpendicular to the output end of the transport box power cylinder is provided in the connecting frame. One end of the swinging member is fixedly connected to the one-way bearing, and the other end is hinged to the output end of the transport box power cylinder.

[0012] Furthermore, one side of the transmission chain is connected to the one-way bearing of the power mechanism through a sprocket, and the other side is connected to the carton push plate. The transmission chain provides power to the carton push plate to realize the forward movement of the carton push plate.

[0013] Furthermore, the bottom of the carton push plate is connected to the transmission chain by a quick-connect pin. The operation of the transmission chain drives the carton push plate forward. The quick-connect pin connection can be easily and quickly disconnected to achieve online replenishment of cartons during equipment operation.

[0014] Furthermore, a push plate sliding guide rod is provided on one side of the carton push plate, the sliding guide rod and the transmission chain extend in the same direction, and the carton push plate is slidably connected to the push plate sliding guide rod. The push plate sliding guide rod is connected to the carton push plate to support the carton push plate, and is fixed at two points with the quick latch to push the carton forward stably.

[0015] Furthermore, the limiting mechanism includes a limiting steering cylinder, a steering shaft and a limiting hinge, the limiting hinge includes a shaft sleeve, a hinge body and a force arm plate, the force arm plate and the hinge body are respectively connected to the side of the shaft sleeve, the output end of the steering cylinder is connected to the force arm plate, and the shaft sleeve is sleeved on the steering shaft. The limiting steering cylinder in the limiting mechanism provides rotational power for the limiting hinge through reciprocating motion. The steering shaft in the limiting mechanism can adjust the rotation angle of the limiting hinge through the steering shaft, so that the limiting hinge stays at the set position to limit the carton. The limiting hinge in the limiting mechanism, under the coordinated action of the limiting steering cylinder and the steering shaft, rotates and stays at the set position, touches and squeezes the side of the carton, prevents the carton from moving and deforming, and ensures that the carton is output to the subsequent workstation in a square and stable manner.

[0016] Furthermore, the folding body is longer than the force applying arm plate.

[0017] The utility model has the following beneficial effects:

[0018] This device is installed on the automatic carton opening machine. On the one hand, it can push the carton through the carton pushing mechanism, which solves the problem of the carton getting stuck when moving along the slide rail. On the other hand, it can adjust the shape of the carton through the limit mechanism, which solves the problem of the carton tilting on the slide rail, ensuring that the carton is output to the subsequent workstation in a square and stable manner.

[0039] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0040] The utility model discloses a stable box conveying device for an automatic box opening machine, such as Figure 1-2 As shown, the device is arranged along the extension direction of the silo slide rail, and includes a box pushing mechanism and a limit mechanism. The box pushing mechanism can push the carton to move along the slide rail to prevent jamming; the limit mechanism can adjust the shape of the carton to ensure that the carton is square and stably output to the subsequent workstation.

[0041] Combination Figure 3 As shown, the box pushing mechanism includes a power mechanism 1, a transmission chain 4 and a carton pushing plate 5. The power mechanism 1 also includes a carton detection switch 3 and a carton conveying power cylinder 11. The carton detection switch 3 in the power mechanism 1 detects whether there is a carton and sends an action signal to the carton conveying power cylinder 11. After receiving the action signal from the carton detection switch 3, the carton conveying power cylinder 11 performs a reciprocating action to provide power for the transportation of the carton. The power mechanism 1 also includes a one-way bearing 2. The one-way bearing 2 cooperates with the reciprocating action of the carton conveying power cylinder 11 to convert the reciprocating action into a one-way forward power output, thereby realizing intermittent one-way power output.

[0042] Furthermore, the one-way bearing 2 is connected to the transport box power cylinder 11 through the swinging member 13. One end of the swinging member 13 is fixedly connected to the one-way bearing 2, and the other end is hinged to the output end of the transport box power cylinder 11. The transport box power cylinder 11 reciprocates linearly, driving the swinging member 13 to swing back and forth, converting the reciprocating linear motion into reciprocating rotational motion and transmitting it to the one-way bearing 2, and the one-way bearing 2 then outputs a one-way motion. Figure 3 As shown, in this embodiment, the swing member 13 is in the shape of a teardrop, with a large end connected to the one-way bearing 2, and a small end connected to the connecting frame 12 at the output end of the transport box power cylinder 11. The connecting frame 12 is provided with a hinge shaft 121 which is perpendicular to the output end of the transport box power cylinder 11. The swing member 13 and the hinge shaft 121 are hinged to realize the conversion between reciprocating linear motion and reciprocating rotational motion.

[0043] In addition, continue to refer to Figure 1 As shown, the transmission chain 4 is arranged parallel to the silo slide rail, and the end is basically aligned with the end of the silo slide rail. One side of the transmission chain 4 is connected to the one-way bearing 2 of the power mechanism through a sprocket, and the other side is connected to the carton push plate 5 to provide power to the carton push plate 5, and the carton push plate 5 is driven by the transmission chain 4 to move forward.

[0044] The carton is located on the silo slide rail, with one pair of side surfaces of the carton parallel to the slide rail direction, and the other pair of side surfaces perpendicular to the slide rail direction. The carton push plate is pushed on the side surface of the carton vertical slide rail, and the carton can be pushed to move along the silo slide rail. The bottom of the carton push plate 5 is connected to the transmission chain 4 in the form of a quick-connect pin, and the operation of the transmission chain 4 drives the carton push plate 5 forward. The quick-connect pin connection form can conveniently and quickly disconnect the carton push plate 5 and the transmission chain 4, so that the carton can be replenished online during the operation of the equipment.

[0045] It is worth mentioning that a push plate sliding guide rod 6 is also provided on one side of the carton push plate 5. The push plate sliding guide rod 6 and the transmission chain 4 are extended in the same direction. The push plate sliding guide rod 6 is connected to the carton push plate 5. The carton push plate 5 can slide on the push plate sliding guide rod 6, which plays a supporting role when the carton push plate 5 moves. Together with the quick-connect pin, the carton push plate 5 is supported at two points to guide the carton to move forward stably.

[0046] Continue to refer Figure 1 As shown, the limit mechanism is located above the end of the transmission chain 4 and on one side of the silo slide rail to adjust the shape of the passing cartons. Figure 2 As shown, the limiting mechanism includes a limiting steering cylinder 7, a steering shaft 8 and a limiting folding leaf 9. The limiting steering cylinder 7 in the limiting mechanism provides rotational power for the limiting folding leaf 9 through reciprocating motion. The steering shaft 8 in the limiting mechanism adjusts the rotation angle of the limiting folding leaf 9 so that the limiting folding leaf 9 stays at the set position to limit the carton. Under the coordinated action of the limiting steering cylinder 7 and the steering shaft 8, the limiting folding leaf 9 in the limiting mechanism rotates and stays at the set position, touching and squeezing the side of the carton to keep the carton square, prevent the carton from moving and deforming, and ensure that the carton is square and stably output to the subsequent workstation.

[0047] Specifically, the steering shaft 8 and the limited steering cylinder 7 are fixedly installed on the frame, and the limited folding leaf 9 includes a sleeve 92, a folding leaf body 91 and a force arm plate 93. The force arm plate 93 and the folding leaf body 91 are respectively connected to the side of the sleeve 92, and the output end of the limited steering cylinder 7 is connected to the force arm plate 93. The sleeve 92 is sleeved on the steering shaft 8. In this embodiment, the limited steering cylinder 7 extends to drive the force arm plate 93 and the folding leaf body 91 to rotate along the direction a around the steering shaft, so that the folding leaf body 91 is roughly perpendicular to the slide rail, and the folding leaf body 91 touches the side of the carton on the slide rail, so that the side of the carton and the folding body 91 are basically parallel, so as to achieve the effect of adjusting the shape of the carton; the limited steering cylinder 7 retracts, and the folding body 91 rotates in the opposite direction of direction a around the steering shaft, and the folding body 91 withdraws from the top of the slide rail, allowing the carton to pass through the channel, and the carton continues to move on the silo slide rail to enter the next station. The length of the force arm plate 93 is relatively short, and the folding body 91 is longer than the force arm plate 93, so the limit steering cylinder 7 does not need to move too much to drive the folding body 9 to rotate and touch the side of the carton.

Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
