[0024] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments and corresponding drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] In order to solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the drawings and embodiments:

[0026] As Figures 1 to 4As shown in the figure, an embodiment of the utility model discloses an automatic packing machine, which includes a feeding mechanism, a cutting device 4 and a measuring device. The feeding mechanism is provided with a conveyor belt 31, a lifting structure 32, a feeding grille 33 and a conveying line 34. The feeding grille 33 is arranged above the conveyor belt 31, and the lifting structure 32 is arranged below the feeding grille 33. The lifting structure 32 drives the packing box to move in a straight line. The discharging end of the conveyor belt 31 is butted against the feeding end of the conveying line 34. The measuring device and the cutting device 4 are respectively arranged above the conveying line 34. The measuring device is provided with a photoelectric sensor. When the packing box leaves the detection point, the photoelectric sensor detects the packing length. The cutting device 4 is provided with a guillotine 41 to cut off the adhesive tape 42. The photoelectric sensor is installed at the detection point position. The packing length is determined according to the first signal and the last signal of the packing box detected by the photoelectric sensor. The detection principle of the photoelectric sensor is prior art and will not be elaborated herein.

[0027] Among them, as Figure 4 shown, the feeding grille 33 is composed of a matrix arrangement of a plurality of feeding ports 331. The overall size of the feeding grille 33 matches the size of the packing box. One remote control is placed in each feeding port 331. The neatly arranged feeding ports 331 enable the manual placement of the remote control through the feeding ports 331, eliminating the stacking and sorting steps, reducing the packing time, improving the packing efficiency, and being suitable for small-sized materials such as remote controls.

[0028] Furthermore, for remote control materials of different sizes and specifications, the size of the feeding port 331 is adjusted so that the remote control materials can smoothly enter the packing box. In this regard, the feeding grille 33 is detachably installed, and the corresponding feeding grille 33 is replaced to produce and package remote controls of different sizes and specifications.

[0029] After adding the feeding grille 33, when the personnel place the remote control, it directly falls into the grid without manual stacking. After the remote control is neatly placed into the packing box through the feeding grille 33, the packing box is moved down to the conveyor belt 31 by the lifting structure 32, and the conveyor belt 31 drives the packing box to move to the conveying line 34. Then, the photoelectric sensor of the measuring device detects that the front side of the packing box reaches the detection point. In cooperation with the action of the conveying line 34 to convey the packing box, the rear side of the packing box leaves the detection point, and the photoelectric sensor detects the required packing length of the packing box. The packing box moves to the lower part of the cutting device 4 for sealing, and finally, the guillotine 41 of the cutting device 4 is controlled to cut off the adhesive tape 42. The length of the adhesive tape 42 cut by the guillotine 41 is the sum of the packing length and the reserved length.

[0030] In some embodiments, it further includes a loading frame 1. The conveyor belt 31 is assembled at the lower end of the loading frame 1. A fixing port 101 is opened at the upper end of the loading frame 1, and the feeding grille 33 is detachably installed in the fixing port 101. The conveyor belt 31 uses a belt, which is a prior structure.

[0031] Further, when loading materials, the feeding grille 33 extends into the packing box near the lower end of the conveyor belt 31. Specifically, when a person places the remote control, the lifting structure 32 jacks up the packing box close to the feeding grille 33. Since the lower end of the feeding grille 33 extends into the internal space of the packing box, the remote controls placed in adjacent feeding ports 331 of the feeding grille 33 are not prone to sliding, tilting, or interfering with the neat arrangement of the remote controls in adjacent feeding ports 331, further improving the stacking efficiency of the remote controls.

[0032] Furthermore, conveyor belts 31 are respectively arranged on both sides of the lifting structure 32. The lifting structure 32 includes a lifting platform 321 and a first driving member (not shown in the figure). The output end of the first driving member is connected to the lifting platform 321, and the lifting platform 321 is located below the feeding grille 33.

[0033] The distance between the conveyor belts 31 on both sides can be adjusted according to the size of the packing boxes of remote controls with different sizes and specifications. During the process of a person placing the remote controls, the packing box is carried by the lifting platform 321, and the first driving member jacks up the lifting platform 321 and the packing box. At this time, the packing box is not in contact with the conveyor belt 31. When placing the remote controls, the conveyor belt 31 will not drive the packing box to move. After the feeding grille 33 is filled with remote controls, the first driving member is controlled to drive the lifting platform 321 and the packing box to descend. The packing box comes into contact with the conveyor belts 31 on both sides, and the conveyor belts 31 drive the packing box to move onto the conveyor line 34, and the lifting platform 321 interferes with the movement of the belt lines on both sides.

[0034] The measuring device accurately measures the packing length of the packing box to ensure that the length of the tape 42 cut by the cutting device 4 matches the packing box, minimizing material waste to the greatest extent, ensuring the stability and consistency of the packing quality, and at the same time realizing the compatibility of packing boxes of remote controls with different specifications and types through the measuring device.

[0035] The cutting device 4 is internally provided with the tape 42 material. The guillotine 41 of the cutting device 4 uses a high-speed rotating tool, and the cutting edge of the tool has been specially treated, being sharp and durable, and capable of quickly and neatly cutting the packaging material. The length direction of the tape 42 in the cutting device 4 is arranged along the conveying direction of the conveyor line 34. The tape 42 in the cutting device 4 is fixed and driven to move through structures such as a rotating shaft and a fixing member. This part of the structure is prior art and will not be elaborated herein.

[0036] The guillotine 41 of the cutting device 4 is arranged near the discharge end of the conveyor line 34. After the packing box moves under the cutting device 4 via the conveyor line 34 to complete the sealing action with the tape, it exits the line from the discharge end of the conveyor line 34. When the rear side of the packing box is a certain distance away from the guillotine 41, the length of the tape 42 pasted on the packing box is the sum of the packing length detected by the measuring device and the reserved length. At this time, the guillotine 41 is controlled to act to cut the tape 42.

[0037] In some embodiments, a heating device (not shown in the figure) is further included. The heating device is installed inside the cutting device 4, and the heating device keeps the tape 42 inside the cutting device 4 within a set temperature range. Further, the heating device uses an existing heating element to keep the temperature inside the housing of the tape 42 within the set temperature range, and the heating element can be a heating sheet. The heating device is mainly provided to prevent the situation where the viscosity of the tape 42 decreases due to extremely cold weather in winter, resulting in poor adhesion. The heating device appropriately heats the material of the tape 42, making the tape 42 easier to shape and fit, and ensuring the tightness and aesthetics of the tape 42 and the packaging box.

[0038] Further, in the sealing process, a combination of heat sealing and gluing can be adopted to ensure the sealing performance of the packaging. The heat sealing device adopts constant temperature control and can accurately adjust the sealing temperature according to the characteristics and requirements of the packaging material, making the seal firm and aesthetic. The gluing part uses an environmentally friendly glue, which is evenly applied to the sealing position through a precise coating device to enhance the strength of the seal. During the sealing process, a pressure regulating device can also be set to ensure that the pressure during sealing is appropriate, neither damaging the remote control nor achieving a good sealing effect.

[0039] In some embodiments, a folding device 5 is further included above the conveyor line 34. The folding device 5 includes a first pressing module 51, a second pressing module 52, and a third pressing module 53 that are oppositely arranged; the third pressing module 53 is arranged close to the conveyor belt 31 side, and the third pressing module 53 is on the center line between the first pressing module 51 and the second pressing module 52.

[0040] After the tape 42 of the previous packaging box is cut, the folding device 5 quickly operates, and through a series of folding plates 501 and push rods 502, the packaging material of the next packaging box is folded according to a preset shape and sequence.

[0041] Specifically, the structures of the first pressing module 51, the second pressing module 52, and the third pressing module 53 are the same, including folding plates 501 and push rods 502. The folding plates 501 are fixedly connected to the push rods 502. Usually, the push rods 502 are connected to the output end of the folding driving member, and the folding driving member drives the push rods 502 and the folding plates 501 to perform linear motion. The folding driving member uses a cylinder. Generally, the third pressing module 53 is arranged close to the conveyor belt side.

[0042] One of the folding methods is as follows: after the packing box enters the conveying line 34 from the discharging end of the conveyor belt 31, the third pressing module 53 is first executed. The front of the packing box is pressed and folded downward by the folding plate 501 of the third pressing module 53. The packing box continues to move forward, and the rear of the packing box is pressed and folded downward by the folding plate 501 of the third pressing module 53. Finally, the first pressing module 51 and the second pressing module 52 are executed. The left and right sides of the packing box are pressed and folded downward by the folding plates 501 of the first pressing module 51 and the second pressing module 52. In this way, the four sides of the packing box are folded and then moved by the conveying line 34 to the lower part of the cutting device 4.

[0043] In practical applications, the actions of the folding plate 501 and the push rod 502 are driven by a high-precision electric cylinder, and their strokes and speeds can be accurately adjusted through the control system to meet the packaging requirements of remote controls of different types and sizes.

[0044] In addition, an included angle is formed between the folding plate 501 of the first pressing module 51 and the second pressing module 52 and the center line of the conveying line 34, and the folding plates 501 of the first pressing module 51 and the second pressing module 52 form a conical shape.

[0045] In some embodiments, a fixed frame 2 is further included. The conveying line 34, the measuring device, the cutting device 4 and the folding device 5 are respectively assembled on the fixed frame 2, and the folding device 5, the measuring device and the cutting device 4 are arranged in sequence along the conveying direction of the conveying line 34.

[0046] At the upper end of the fixed frame 2, two transverse frames 201 are oppositely arranged. The length direction of the transverse frame 201 is consistent with the length direction of the conveying line 34. The photoelectric sensor (not shown in the figure) of the measuring device is installed on the transverse frame 201, and a transmissive photoelectric sensor is used to detect the packing length of the packing box.

[0047] Furthermore, the folding device 5 is hingedly installed on the fixed frame 2. The angles of the first pressing module 51, the second pressing module 52 and the third pressing module 53 are adjusted according to the packing boxes of different specifications of remote controls, so that the folding plate 501 can smoothly press and fold the edges of the packing boxes with different heights and widths.

[0048] In some embodiments, a first positioning mechanism (not shown in the figure) and a second positioning mechanism (not shown in the figure) are further included on the conveying line 34. The first positioning mechanism and the second positioning mechanism are oppositely arranged along the length direction of the conveying line 34, and the first positioning mechanism and the second positioning mechanism limit the packing box to move along the center line of the conveying line 34.

[0049] Furthermore, the first positioning mechanism and the second positioning mechanism have the same structure, including a baffle and a positioning driving member. The baffle is assembled at the output end of the positioning driving member.

[0050] Adopt a combination of conveyor line 34 and positioning device. The conveyor line 34 is made of high-strength and wear-resistant materials, and has appropriate friction on the surface to ensure that the remote control packaging box moves forward smoothly during transportation without slipping or stagnating. The conveyor line 34 is an existing structure. The drive motor of the conveyor line 34 uses a speed-regulating motor, which can flexibly adjust the conveying speed according to production requirements. On both sides of the conveyor line 34, a first positioning mechanism and a second positioning mechanism are provided. These positioning devices are composed of photoelectric sensors and adjustable baffles. When the remote control is placed on the conveyor line 34, the photoelectric sensor will detect its position and transmit the signal to the control system. The control system will adjust the position of the baffle according to the detected position information, so as to accurately guide the remote control to the packing position, ensuring that each remote control can be packed at the same position in the subsequent operation, improving the accuracy and consistency of packing.

[0051] In some embodiments, an automatic counter and sorting device are installed at the discharge end of the conveyor line 34. The completed remote control packaging box is sent out through the discharge conveyor belt 6 connected to the discharge end of the conveyor line 34. The discharge conveyor belt 6 also has a speed-regulating function and can match the rhythm of the entire production line. At the end of the discharge conveyor belt 6, an automatic counting and sorting device is provided to count and classify the packed remote controls, which is convenient for subsequent storage and transportation. At the same time, in order to ensure the safety of operators, a guardrail and safety sensors are also provided in the discharge part. When someone approaches the dangerous area, the equipment will automatically stop to avoid accidents.

[0052] The automatic packing machine realizes efficient, accurate and stable packing operations through the coordinated work of various parts such as the feeding mechanism, the cutting device 4, the measuring device, the folding device 5, the heating device, the positioning mechanism, and the lifting structure 32, significantly improving the production efficiency and packing quality, and reducing the production cost and labor intensity.

[0053] The control system of the automatic packing machine uses advanced sensors and microprocessors to achieve a high degree of intelligence and automation. The sensors include position sensors, pressure sensors, temperature sensors, etc., which real-time monitor various parameters during the packing process. The microprocessor receives the signals transmitted by the sensors, analyzes and processes them according to the preset programs and algorithms, and then issues corresponding control instructions to adjust the actions of each component.

[0054] Furthermore, when it is detected that the size of the remote control changes, the microprocessor will automatically adjust the cutting size and folding parameters of the packaging material; when it is found that there is abnormal pressure during the packaging process, it will timely adjust the action force of the relevant components to ensure the packing quality and the safe operation of the equipment. In addition, the control system also has a fault diagnosis and alarm function. Once the equipment fails, it can quickly locate the fault point and remind the operator to handle it through the sound and light alarm device.

[0055] At the front end of the conveyor belt 31, there is a packing box feeding mechanism. Packaging materials are placed at the bottom of the packing box feeding. The packing box feeding is provided with multiple groups of cylinders and folding plates for folding the packaging materials into packing boxes. The packing box feeding mechanism adopts the existing structure for folding packing boxes, and will not be elaborated here. The folded packing boxes can be sent to the lifting table 321 through the feeding mechanism or manually.

[0056] The main functions of the present utility model are as follows:

[0057] 1. The present utility model designs a feeding grille, which can accurately and quickly place the remote control into the packing box without manual stacking, reducing the stacking and sorting working hours and improving the efficiency of remote control packing. Then, through the cooperation of the lifting structure and the conveyor belt, the packing box filled with remote controls is moved into the conveyor line to complete the measurement, folding and sealing actions.

[0058] 2. The present utility model designs a measuring device, which uses a photoelectric sensor to cooperate with the conveyor line to complete the measurement of the packing length of the tape required for the packing box, ensuring the stability and consistency of the packing quality. At the same time, it realizes the precise processing of the tape packaging materials, reduces waste and lowers the production cost.

[0059] In summary, after reading the documents of the present utility model, those of ordinary skill in the art can make various corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present utility model, and all of them fall within the scope protected by the present utility model.
