Description

Technical Field

[0001] This utility model relates to the field of heat shrink packaging machine technology, specifically a reciprocating high-speed automatic heat shrink packaging machine. Background Technology

[0002] A heat shrink packaging machine is a device that uses heat shrink film to package items. It is also known as a shrink machine or film wrapping machine. Its main function is to wrap the product with heat shrink film and then heat it to shrink the film and tightly wrap the product. This packaging method can not only protect the product, but also reduce the risk of being opened or stolen. It is especially suitable for tight packaging of multiple items and pallet packaging.

[0003] A search revealed a Chinese patent document disclosing a reciprocating high-speed automatic heat shrink packaging machine [Application No.: CN202420221257.9]. This reciprocating high-speed automatic heat shrink packaging machine includes a base and a heat shrink box. The heat shrink box is fixedly connected to the upper surface of the base. Both the base and the heat shrink box are fixedly connected to the outer wall of the packaging box. A reciprocating mechanism is installed inside the heat shrink box, and a dust removal mechanism is installed inside the packaging box. A blower and a heating box are fixedly connected to the upper surface of the heat shrink box, and the blower and the heating box are connected by a connecting pipe.

[0004] The packaging machine disclosed in this patent can shrink the heat shrink film with hot air to package the product. However, the motor is located inside the heat shrink box, which can affect the heat dissipation of the motor and thus affect its normal operation. In addition, it is inconvenient for the operator to accurately start the motor according to the movement of the product, and the heating effect of the hot air on the heat shrink film is easily affected. Utility Model Content

[0005] The purpose of this invention is to provide a reciprocating high-speed automatic heat shrink packaging machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating high-speed automatic heat shrink packaging machine, comprising a conveyor body, an outer frame installed on the top of the conveyor body, and further comprising:

[0007] An air supply pipe is fixedly installed through the top of the outer frame. A retractable hose is connected to the bottom of the air supply pipe. An air blowing frame is connected to the bottom of the retractable hose. An exhaust frame slides through the surfaces on both sides of the air blowing frame.

Triangular plates are fixedly connected to the surfaces of the exhaust frames on both sides. A heating plate is fixedly inserted through the top of the gas storage box. One end of the air supply pipe is fixedly inserted through the gas storage box. A fan is fixedly connected to the surface of the gas storage box. The air supply end of the fan is connected to the gas storage box.

[0009] Preferably, a limiting plate is fixedly connected to the surface of the exhaust frame, and the surface of the limiting plate is slidably connected to the inner wall of the air blowing frame.

[0010] Preferably, the winding mechanism includes a winding roller, a horizontal plate, and a motor. The winding roller rotates through the top of the outer frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In use, this invention utilizes an infrared transmitter and receiver to allow the air-blowing frame and exhaust frame to move with the product. During this process, the winding roller pulls the rope, which in turn moves the air-blowing frame. Before use, the position of the exhaust frame can be adjusted according to the product width so that the air-blowing frame and exhaust frame can work together to better heat the heat-shrink film on the product surface. This improves the wrapping effect of the heat-shrink film on the product and solves the problem in some current packaging machines where heat dissipation is easily affected when the motor is placed inside the heat-shrink box, and the position of the hot air blowing on the product surface is easily deviated, thus affecting the shrinkage effect of the heat-shrink film.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 As shown, a reciprocating high-speed automatic heat shrink packaging machine includes a conveyor body 1 and an outer frame 2 installed on the top of the conveyor body 1. An air supply pipe 16 is fixedly inserted through the top of the outer frame 2. A retractable hose 15 is connected to the bottom of the air supply pipe 16. An air blowing frame 3 is connected to the bottom of the retractable hose 15. Exhaust frames 4 slide through the surfaces of both sides of the air blowing frame 3. An infrared transmitter 8 and an infrared receiver 9 are respectively installed at the bottom of the exhaust frames 4. A controller 20 is fixedly connected to the top of the outer frame 2. The infrared transmitter 8 and the infrared receiver 9 are electrically connected to the controller 20. A limit plate 5 is fixedly connected to the surface of the exhaust frame 4. The air blowing frame 3 is slidably connected to the inner wall of the air blowing frame 3. The movement range of the exhaust frame 4 can be limited by the cooperation of the air blowing frame 3 and the limiting plate 5. A guide mechanism 7 is installed on the top of the air blowing frame 3, and a winding mechanism 6 is installed on the top of the outer frame 2. Triangular plates 10 are fixedly connected to the surfaces of both exhaust frames 4. A pushing mechanism 14 is installed on the top of the outer frame 2. An air storage box 17 is fixedly connected to the top of the air storage box 17. A heating plate 18 is fixedly passed through the top of the air storage box 17. One end of the air supply pipe 16 is fixedly passed through the air storage box 17. A fan 19 is fixedly connected to the surface of the air storage box 17. The air supply end of the fan 19 is connected to the air storage box 17. A controller 20 is located at the bottom of the fan 19.

[0025] The winding mechanism 6 includes a winding roller 61, a horizontal plate 62, and a motor 63. The winding roller 61 rotates through the top of the outer frame 2. The horizontal plate 62 is fixedly connected to the inner wall of the outer frame 2. The bottom of the winding roller 61 is rotatably connected to the top of the horizontal plate 62. The motor 63 is fixedly connected to the top of the outer frame 2. The top of the winding roller 61 is fixedly connected to the output shaft of the motor 63. A pull rope is wound on the surface of the winding roller 61. One end of the pull rope is fixedly connected to the surface of the air blowing frame 3. When the motor 63 starts, it drives the winding roller 61 to rotate. The horizontal plate 62 supports the winding roller 61. When the winding roller 61 rotates, it drives the air blowing frame 3 to move through the winding of the pull rope. The air blowing frame 3 and the exhaust frame 4 move with the items on the top of the conveyor body 1 so as to heat the heat shrink film on the surface of the items.

[0026] The guiding mechanism 7 includes a vertical plate 71, a guide rod 72, and a tension spring 73. The vertical plate 71 is fixedly connected to the top of the air blowing frame 3. The guide rod 72 slides through the vertical plate 71. The two ends of the guide rod 72 are fixedly connected to the two sides of the inner wall of the outer frame 2, respectively. The tension spring 73 is sleeved on the surface of the guide rod 72. When the air blowing frame 3 is moved by the winding of the pull rope, the vertical plate 71 moves accordingly, and the tension spring 73 is stretched under force. Then, under the action of the elastic force of the tension spring 73, the vertical plate 71 can drive the air blowing frame 3 to move in the opposite direction and reset.

[0027] The pushing mechanism 14 includes an electric push rod 141 and a push plate 142. The electric push rod 141 is fixedly connected to the top of the outer frame 2. The piston rod of the electric push rod 141 slides through the top of the outer frame 2 and is fixedly connected to the top of the push plate 142. Both sides of the bottom of the push plate 142 are fixedly connected to the extrusion plates 143. The surface of the extrusion plates 143 is in contact with the surface of the triangular plate 10. Both sides of the top of the air blowing frame 3 are fixedly connected to the vertical plates 12. The tops of the two exhaust frames 4 are fixedly connected to the vertical plates 11. The vertical plates 11 and 142 are fixedly connected to the vertical plates 142. A compression spring 13 is fixedly connected between the two 12. After the electric push rod 141 is started, the push plate 142 drives the extrusion plate 143 to rise. At this time, the triangular plate 10 is squeezed by the extrusion plate 143 and drives the exhaust frame 4 to move. When the push plate 142 drives the extrusion plate 143 to fall, under the action of the compression spring 13, the triangular plate 10 can drive the exhaust frame 4 to move in the direction of the inner wall of the outer frame 2. Through the cooperation of the extrusion plate 143 and the triangular plate 10, the position of the exhaust frame 4 can be adjusted, thereby increasing the flexibility of the packaging machine.

[0028] The motor 63, heating plate 18 and fan 19 are all electrically connected to the controller 20. When the infrared receiver 9 cannot receive infrared light, the controller 20 can start the fan 19 to input outside air into the air storage box 17 and inject it into the retractable hose 15 through the air supply pipe 16. During this process, the heating plate 18 can heat the air. The heated air is discharged through the air blowing frame 3 and the exhaust frame 4, which can heat the heat shrink film on the surface of the item.

[0029] The electric actuator 141, motor 63, fan 19 and controller 20 are considered prior art. The specific structure and working principle of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0030] It should be noted that the moving speed of the air blowing frame 3 and the exhaust frame 4 is controlled by the rotational speed of the winding roller 61. Controlling the rotational speed of the winding roller 61 makes it easier for the pulling speed of the pull rope to match the conveying speed of the conveyor body 1. The speed control of the winding roller 61 can be achieved by using conventional selections in this field, which will not be elaborated here.

[0031] Working principle: The operator first adjusts the position of the exhaust frame 4 according to the width of the item. During this process, the operator starts the electric push rod 141 to drive the push plate 142 and the squeezing plate 143 to rise. The squeezing plate 143 rises and squeezes the triangular plate 10, thereby adjusting the position of the exhaust frame 4. When the item moves with the conveyor body 1 between the infrared transmitter 8 and the infrared receiver 9, the infrared receiver 9 is blocked by the item and cannot receive infrared rays. The blower 19 and the motor 63 start at the same time. Outside air is injected into the air storage box 17 and heated by the heating plate 18. The heated air is injected into the air blowing frame 3 and the exhaust frame 4 through the air supply pipe 16 and the retractable hose 15, and then discharged to the surface of the item through the air blowing frame 3 and the exhaust frame 4 to heat the heat shrink film. The motor 63 drives the winding roller 61 to rotate, the pull rope is wound up and drives the air blowing frame 3 to move, so that the air blowing frame 3 and the exhaust frame 4 can move with the item. At this time, the packaging machine can better shrink the heat shrink film on the surface of the item by heating, thereby packaging the item.
