Description

Technical Field

[0001] The utility model relates to the technical field of sleeve film sealing and cutting, in particular to a box separating device for a heat shrink packaging machine. Background Art

[0002] A shrink wrap machine is a device used to wrap products in heat-shrink film by heating and shrinking them, achieving both protection and aesthetics. A shrink wrap machine typically consists of a conveyor belt, a heating chamber, and a shrinking zone. The conveyor belt transports the product to be packaged into the heating chamber, which contains one or more heaters that provide the necessary heat. The shrink film is pulled from a roller and fed by the conveyor belt over the product, where it is lowered and wrapped around it. Once wrapped, it enters the shrinking zone, where the film is heated and shrunk to the desired dimensions.

[0003] Existing sleeve sealing and shrink packaging machines have design limitations. They can only accommodate one medicine box at a time and cannot accommodate multiple boxes or boxes of varying sizes. This limitation significantly reduces production efficiency and diminishes the equipment's practicality and application scope.

[0004] A Chinese patent application, CN 206984488U, has been proposed to address the aforementioned technical issues. The patent document discloses a technical solution comprising a conveyor belt, channel side panels positioned above the left and right sides of the conveyor belt, and vertical baffles positioned transversely on the channel side panels. The gaps between the vertical baffles, the conveyor belt, and the channel side panels form a box-splitting channel. This box-splitting device for a sleeve sealing and heat shrink packaging machine boasts a scientific design, a simple structure, ease of box separation, improved packaging efficiency, and reduced operator workload. Utility Model Content

[0005] The purpose of the present utility model is to provide a carton separating device for a heat shrink packaging machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A box-splitting device for a heat shrink packaging machine comprises a body; a laminating device, a film cutting device and a heat shrinking device are provided on the body; a conveying trough is provided on the body, and a conveyor belt is provided on the conveying trough; a box-splitting component is provided on one side of the laminating device; the box-splitting component comprises a first conveyor belt and a second conveyor belt; a plurality of partitions are vertically fixed on the first conveyor belt; a sensor is provided at a position where the first conveyor belt and the second conveyor belt are close to each other, and a signal transmitter is provided on the baffle, and the sensor can identify the signal sent by the signal transmitter; a control motor and a first controller are provided in the first conveyor belt, and the sensor and the first controller are electrically connected.

[0008] By setting up the first conveyor belt, when packaging the medicine bottle boxes, first, put the medicine bottle boxes between the adjacent partitions on the first conveyor belt, start all the conveyor belts and conveyor belts, and the medicine boxes on the first conveyor belt are conveyed to the second conveyor belt along with the transmission of the first conveyor belt. The baffle is horizontal, and then the medicine boxes enter the second conveyor belt; when the medicine boxes enter the second conveyor belt, the baffle is horizontal. At this time, the signal transmitter on the baffle will transmit a signal to the sensor. When the sensor receives the signal, it will transmit it to the controller. The controller will send an instruction to the control motor. The content of this instruction is to stop the first conveyor belt and delay for a period of time before starting again. When the first conveyor belt stops, we can manually add medicine boxes to the first conveyor belt to achieve orderly placement of medicine boxes and prevent confusion.

[0009] A further improvement of the technical solution of the present utility model is that baffles are provided on the second conveyor belt, and the baffles are symmetrically arranged on both sides of the conveying trough; and the baffles are fixedly connected to the sides of the conveying trough.

[0010] The above technical solution adopts a baffle. When the medicine box enters between the baffles, the baffle is limited to ensure that the medicine box is in the correct position when entering the laminating equipment and subsequent steps, preventing problems caused by incorrect positioning.

[0011] A further improvement of the technical solution of the present invention is that a discharge box is provided above the first conveyor belt, and the discharge box can automatically place the medicine box between adjacent partitions on the first conveyor belt.

[0012] By adopting the above technical solution, a discharge box is provided, which can automatically place the medicine box on the first conveyor belt, eliminating the need for workers to manually place the medicine box on the first conveyor belt, thereby improving work efficiency.

[0013] A further improvement of the technical solution of the present utility model is that: a first electric push rod is fixedly provided on the side of the baffle and the conveying trough, a photoelectric sensor is provided on the opposite side of the baffle, an emitting part of the photoelectric sensor is provided on the baffle on one side of the conveying trough, and a receiving part of the photoelectric sensor is provided on the baffle on the other side; a second controller and a power device are provided in the first electric push rod, and the photoelectric sensor and the second controller are electrically connected.

[0014] The above-mentioned technical solution is adopted, in which a baffle and a first electric push rod are set. When the medicine box enters the second conveyor belt, it will move towards the laminating device along with the conveyor belt. When it passes through the photoelectric sensor of the baffle, when the medicine box passes the sensor, it will block the light emitted by the signal transmitter and generate an occlusion signal, thereby triggering the sensor to input a signal to the first controller. The controller controls the action of the first electric push rod, and the first electric push rod drives the baffle to press the medicine box into place.

[0015] A further improvement of the technical solution of the present utility model is that: the discharge box includes a box body, a discharge trough is provided on the box body, a push plate is provided near the bottom of one side of the discharge trough, a second electric push rod is provided between the push plate and the discharge trough, a discharge port is provided at the bottom of the discharge box, a channel is provided between the discharge port and the discharge trough, the position of the discharge port is directly above one group of adjacent partitions of the first conveyor belt; the timing of the second electric push rod is consistent with that of the first conveyor belt.

[0016] The above-mentioned technical solution is adopted. In this solution, a discharge trough is set up. When discharging, the medicines to be packaged are placed in the discharge trough. Multiple medicine boxes can be placed at one time. When the entire packaging machine is working, when the first conveyor belt is paused, the second electric push rod is actuated, and the electric push rod drives the push plate to move. The push plate pushes a medicine box at the bottom of the discharge trough from the channel into the discharge port, and finally falls from the discharge port into a group of empty adjacent partitions on the first conveyor belt.

[0017] A further improvement of the technical solution of the present invention is that the material storage box does not completely cover the top of the first conveying trough, and an observation port is left.

[0018] The above technical solution is adopted, in which an observation port is provided to prevent some medicine boxes input into the conveying trough through the material box from not falling correctly between adjacent partitions, and the medicine boxes are manually placed in the correct position from the partition.

[0019] A further improvement of the technical solution of the present invention is that by providing a baffle and a spring, when the medicine box enters the second conveyor belt, as the second conveyor belt moves to the baffle, the baffle keeps the medicine box in place.

[0020] The above technical solution is adopted, in which a spring and a baffle are set. When the medicine bottle box enters between the baffles and the size of the medicine box is larger than the baffle, the baffle is squeezed by the inclined surface, causing the spring to contract. The medicine box is pressed into place by the contraction of the spring to prevent problems such as incorrect lamination during lamination.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0022] 1. The utility model provides a box separating device for a heat shrink packaging machine. By setting a first conveyor belt and a baffle, the medicine box is placed between adjacent partitions on the first conveyor belt, and all the conveyor belts and conveyor belts are started. The medicine box on the first conveyor belt is conveyed to the second conveyor belt along with the conveyance of the first conveyor belt. The baffle is horizontal, and then the medicine box enters the second conveyor belt; when the medicine box enters the second conveyor belt, the baffle is horizontal. At this time, the signal transmitter on the baffle will transmit a signal to the sensor. When the sensor receives the signal, it will transmit it to the controller. The controller will transmit an instruction to the control motor. The content of this instruction is to stop the first conveyor belt and delay for a period of time before starting again. When the first conveyor belt stops, we can manually replenish medicine boxes on the first conveyor belt to achieve orderly placement of medicine boxes and prevent confusion.

[0023] 2. The utility model provides a box separating device for a heat shrink packaging machine. By setting a material discharge box, the material discharge box can automatically place medicine boxes on the first conveyor belt, eliminating the need for workers to manually place medicine boxes into the first conveyor belt, thereby improving work efficiency.
