[0002] Currently, with economic development and consumers' increasing demands for gift packaging, the market demand for gift box outer film packaging machines is constantly growing, and this demand is driving the continuous innovation and development of the packaging machinery industry.

[0003] However, for large factories that need gift box packaging, manual lamination was usually used in the past, but traditional manual lamination has problems such as low production efficiency and insufficient stability.

[0004] Therefore, how to provide a gift box outer film packaging machine, control system, and control method that can solve the above problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a gift box outer film packaging machine, a control system, and a control method, which realizes a relatively stable and automated packaging operation, which can not only reduce the input of manpower and material resources and reduce production costs, but also further improve production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A gift box outer film packaging machine includes: a film feeding module, a feeding module, a sealing and cutting module, a film stretching module, and a heat shrinking module arranged sequentially on the machine body according to the working sequence;

[0008] The film feeding module is used to feed out the roll film and punch holes in the roll film. The feeding module is used to adjust the roll film according to the size parameters of the gift box product. The sealing and cutting module is used to cut the film and complete the sealing. The film pulling module is used to provide the power for the film to move forward. The heat shrinking module is used to shrink the sealed and cut film-covered gift box to completely wrap it.

[0011] Heat shrink motors and heat shrink conveyor belt motors.

[0012] The present invention also provides a control system for a gift box outer film packaging machine, comprising:

[0013] The sensor detection module is used to detect the position information of the gift box to be processed;

[0014] The control module, wherein the sensor detection module is connected to the control module, is used to process the position information and output corresponding control commands;

[0015] A motor control module, connected to the control module, is used to receive the control commands and perform motor control according to the control commands.

[0016] Preferably, the control module includes:

[0017] A control unit, which is connected to the sensor detection module, is used to receive the position information and determine whether the gift box to be processed has reached the preset position;

[0018] The I / O allocation unit, which is connected to the control unit, is used to allocate I / O ports to the film feeding module, feeding module, sealing and cutting module, film stretching module, film taking-up module, and heat shrinking module.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention discloses a gift box outer film packaging machine, comprising: a film feeding module, a feeding module, a sealing and cutting module, a film stretching module, and a heat shrinking module arranged sequentially on the machine body according to the working order;

[0036] The film feeding module is used to feed out the roll film and punch holes in the roll film. The feeding module is used to adjust the roll film according to the size parameters of the gift box product. The sealing and cutting module is used to cut the film and complete the sealing. The film pulling module is used to provide the power for the film to move forward. The heat shrinking module is used to shrink the sealed and cut film-covered gift box to completely wrap it.

[0037] In one specific embodiment, it further includes a film collection module for recycling excess film waste.

[0038] In one specific embodiment, the film feeding module, the feeding module, and the film pulling module are each equipped with a corresponding film feeding motor, a feeding motor, and a film pulling motor in sequence, and the heat shrinking module is equipped with a heat shrinking motor and a heat shrinking conveyor belt motor.

[0039] For details, see Figure 1 As shown, the film feeding module consists of a film support roller 2, a needle wheel 3, a brush roller 4, a rubber roller 5, a film separating rod 6 to prevent static electricity, and a guide roller 7. The feeding module is tasked with making corresponding adjustments according to the height and width of the product. It consists of a feeding conveyor belt 8, upper and lower film separating triangle plates 9, a feeding positioning rod, an adjusting screw, and a handwheel. The function of the upper and lower film separating triangle plates is to rotate the double-layer folded POF film 1 by 90°.

[0040] The sealing and cutting module is tasked with cutting the film and sealing it. It mainly consists of upper and lower knife holders 17 and a discharge conveyor belt 19. The sealing and cutting are completed by driving the gear rack 11 through the cylinder 10.

[0041] The film-pulling module provides the power for the film to move forward, which can be achieved using an upper and lower traction synchronous belt; the heat-shrink module refers to shrinking the sealed and cut film-covered gift box to completely wrap it, mainly composed of a heat-shrink oven 16 and a heat-shrink oven conveyor belt 15. The working principle of the heat-shrink oven is that after the heating element is preheated, the fan motor drives the fan to blow hot air into the oven, thereby causing the film on the outside of the gift box to automatically shrink and tighten, completing the packaging work; the film collection system recycles excess waste material, mainly composed of waste film guide wheels 13, film collection swing rods 14 and waste film wheels 12.

[0042] The film-supporting roller 2, brush roller 4, rubber roller 5, anti-static film-separating rod 6, guide roller 7, and feeding conveyor belt 8 are arranged in parallel on the machine body 20, and multiple pin wheels 3 are set on the brush roller 4; the cylinder 10, gear rack 11, waste film wheel 12, waste film guide wheel 13, and film-collecting swing rod 14 are all set inside the machine body 20. The cylinder 10 is connected to the gear rack 11. The discharge conveyor belt 19 is equipped with a sealing and cutting knife 17 and a synchronous pulley 18. Multiple synchronous pulleys 18 are connected by belts. The film-collecting swing rod 14, waste film guide wheel 13, and film-collecting swing rod 14 are all set inside the machine body 20. When the packaging film is not installed, the film guide wheel 13 and the waste film wheel 12 are connected to the machine body 20 respectively. When the packaging film is installed, the film is placed on the film support roller, and passes through the rubber roller 5, the film separating rod 6, the guide roller 7 and the upper and lower film separating triangle plates in sequence. Finally, the film is clamped between the upper and lower synchronous wheels 18 to realize the subsequent film pulling function. After that, several manual sealing and cutting will be performed first. The purpose is to make the film run smoothly and at the same time wrap the cut waste film around the film receiving swing rod 14, the waste film guide wheel 13 and the waste film wheel 12 in sequence, so as to prepare for the continuous film receiving in the subsequent automatic mode.

[0043] The heat shrink oven conveyor belt 15 and the heat shrink oven 16 are mounted on the machine body 20.

[0044] The specific working principle is as follows: First, install the double-layer folded film on the equipment, then power on and initialize, start the gift box outer film packaging machine, and preheat the sealing and cutting knife and heat shrink oven. Adjust equipment parameters, such as temperature, to ensure normal operation. Place the product to be packaged on the feeding conveyor belt, and adjust the height of the triangular plate and the width of the feeding worktable by adjusting the handwheel to adapt to the size of the gift box. Select automatic or manual mode. First, select manual mode, press the manual film feeding button to let the film move smoothly, and release it to stop; press the manual sealing and cutting button to leave a slit at the front of the folded film for subsequent packaging. Then select automatic mode. After the photoelectric switch at the feeding point senses the object, the feeding conveyor belt starts. When the photoelectric sensor at the end of the feeding conveyor belt detects the arrival of the gift box, the film pulling and feeding system provides the power for the film to move forward. Excess waste film is wound into the waste film wheel by the film collection system to reduce waste. After the product reaches the sealing and cutting position, it is detected by the sealing and cutting limit switch and begins sealing and cutting. The cutter completes the sealing and cutting operation within the preset time. After sealing and cutting, the discharge conveyor belt starts, and the gift box enters the heat shrink section. Detected by a heat shrink photoelectric switch, the outer film is shrunk within a preset time. After shrinking, the heat shrink conveyor belt starts again. When the gift box reaches the delivery limit, the heat shrink conveyor belt stops, completing the packaging of the gift box.

[0045] See Figure 2 As shown, the present invention also provides a control system for a gift box outer film packaging machine according to any of the above embodiments, wherein the control system can be disposed inside the machine body, including:

[0046] The sensor detection module 101 is used to detect the position information of the gift box to be processed. The sensor detection module 101 may include a photoelectric sensor and a temperature sensor. The photoelectric sensor collects the position information of the gift box to be processed, and the temperature sensor detects the shrinkage temperature during the processing.

[0047] The control module 201 and the sensor detection module 101 are connected to the control module 201 and are used to process the position information and output corresponding control commands.

[0048] The motor control module 301 is connected to the control module 201 and is used to receive control commands and complete motor control according to the control commands.

[0049] In one specific embodiment, the control module 201 includes:

[0050] Control unit 2011, connected to sensor detection module 101, is used to receive position information and determine whether the gift box to be processed has reached the preset position. This can be implemented using a PLC; its specific external wiring diagram can be found in [reference needed]. Figure 3 As shown;

[0051] I / O allocation unit 2012 is connected to control unit 2011 and is used to allocate I / O ports to film feeding module, feeding module, sealing and cutting module, film stretching module, film taking-up module and heat shrinking module.

[0052] Specifically, the I / O allocation unit 2012 determined the I / O port allocation of the gift box outer film packaging machine according to the address allocation principle, with 16 inputs and 12 outputs. The specific allocation is shown in Tables 1 and 2.

[0062] See Figure 3 As shown, this embodiment of the invention also provides a control method for a gift box outer film packaging machine, including the following steps:

[0063] Start the gift box outer film packaging machine, preheating the sealing and cutting module and the heat shrinking module;

[0064] Select the operation mode. When the automatic mode is selected, it will determine whether the gift box to be processed is placed on the feeding conveyor belt. When the manual mode is selected, the process will be completed manually.

[0065] When the gift box to be processed is on the feeding conveyor belt, the system determines whether the gift box is at the end of the feeding conveyor belt while the feeding conveyor belt is running. The position determination can be achieved by photoelectric sensors.

[0066] When the determination is correct, start the film feeding motor and the film pulling motor, and at the same time, determine again whether the gift box to be processed is in the sealing and cutting position;

[0067] When the gift box to be processed is in the sealing and cutting position, the sealing and cutting operation is carried out through the sealing and cutting module. After the sealing and cutting operation is completed, the discharge conveyor belt will take the gift box to be processed with the outer film on through the heat shrink module, so that the outer film shrinks until it completely covers the gift box to be processed, and the operation ends.
