[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figures 1-6 As shown, an automatic conveying and packaging machine for cookies includes two support plates 1. A conveyor belt 2 is movably connected to the upper part of the opposite side of the two support plates 1. A base 16 is fixedly connected to the right side of the two support plates 1. A base 5 is fixedly connected to the right side of the base 16. A drive mechanism 3 is movably connected to the opposite side of the two support plates 1.

[0029] The drive mechanism 3 includes a motor 31, which is fixedly connected to the right side of the rear of the support plate 1. Two drive shafts 32 are rotatably connected to the upper part of the opposite side of the two support plates 1. A brush roller 13 is rotatably connected to the middle of the opposite side of the two support plates 1. Three transmission wheels 33 are rotatably connected to the front side of the support plate 1. A toothed belt 34 is meshed with the outer periphery of the three transmission wheels 33. The two upper transmission wheels 33 are fixedly connected to the front end of the drive shaft 32, and the lower transmission wheel 33 is fixedly connected to the front end of the brush roller 13.

[0030] It should be noted that the two support plates 1 are arranged opposite each other, providing a stable mounting platform for each component. Conveyor belt 2 is the main channel for transporting cookies within the equipment. Base 16 serves as a support structure for metering mechanism 4, ensuring its stable operation. Base 5 supports conveyor belt 10, ensuring its stable operation.

[0031] Motor 31 provides power for the rotation of drive shaft 32 and brush roller 13, and is the core power component for the automated operation of the equipment. Drive shaft 32, through frictional contact with conveyor belt 2, converts the power transmitted by motor 31 into the motion of conveyor belt 2, driving the cookies on conveyor belt 2 forward. Transmission wheels 33 are interconnected via toothed belts 34, forming a transmission system. The function of transmission wheels 33 and toothed belts 34 is to transmit the power of motor 31 to drive shaft 32 and brush roller 13, ensuring that conveyor belt 2 and brush roller 13 rotate simultaneously and in the same direction. The main function of brush roller 13 is to clean the lower surface of conveyor belt 2 during cookie transport, removing debris, dust, and other impurities that have accumulated on conveyor belt 2 during production.

[0032] like Figure 3 As shown, guide blocks 9 are fixedly connected to the lower part of the two support plates 1 on opposite sides. The left and right sides of the upper surface of the guide blocks 9 are inclined towards the middle. A collection box 15 is slidably connected to the middle of the guide blocks 9. A vacuum adsorber 14 is fixedly connected to the lower part of the middle of the two support plates 1 on opposite sides. A measuring mechanism 4 is fixedly connected to the upper surface of the base 16.

[0033] It should be noted that the guide block 9 is designed to guide and collect cookie crumbs, packaging waste, and other debris that may fall from conveyor belt 2 or deviate from their position during transport. Its inclined upper surface allows these debris to slide automatically towards the center and eventually fall into the collection box 15 below, facilitating subsequent centralized cleaning. The collection box 15 collects cookie crumbs, packaging waste, and other debris that slides down from the guide block 9. Its sliding design allows for easy removal from the equipment for cleaning once full, ensuring cleanliness during continuous operation. The vacuum suction unit 14 generates negative pressure to adsorb cookie particles or light impurities inside the brush roller 13, then directly discharges the crumbs into the collection box 15.

[0034] like Figure 2 and Figure 3As shown, the measuring mechanism 4 includes a measuring instrument 41, which is fixedly connected to the upper surface of the base 16. A tray 44 is rotatably connected to the upper surface of the measuring instrument 41. Two drainage blocks 45 distributed front to back are fixedly connected to the right side of the inner cavity of the tray 44. Two electric push rods 42 distributed front to back are fixedly connected to the right side of the base 16. A slider 43 is fixedly connected to the output end of the electric push rod 42. The slider 43 is slidably connected to the lower right side of the tray 44.

[0035] It should be noted that the measuring device 41 can accurately measure the weight or quantity of cookies placed on the tray 44, and feeds the measurement data back to the equipment's control system in real time through built-in sensors and a measurement system. The electric push rod 42, based on the measurement results from the measuring device 41, pushes the slider 43 to slide on the lower right side of the tray 44 through its own telescopic movement. Under the action of the electric push rod 42, the slider 43 slides along the track on the right side of the tray 44, converting the linear motion of the electric push rod 42 into the tilting motion of the tray 44, thus transmitting and supporting the movement of the tray 44. The tray 44 is used to temporarily store cookies transported from the conveyor belt 2. The guide block 45 guides the cookies to slide smoothly into the packaging bags 11 on the lower conveyor belt 2 10 when the tray 44 is tilted, ensuring that the cookies enter the packaging bags 11 accurately and orderly.

[0036] like Figure 4 As shown, a support frame 6 is fixedly connected to the rear left side of the base 5, a second conveyor belt 10 is movably connected to the upper part of the base 5, a guide plate 12 is fixedly connected to the rear side of the upper surface of the base 5, a packaging bag 11 is movably connected to the upper surface of the second conveyor belt 10, and a lifting mechanism 7 is movably connected to the inner cavity of the support frame 6.

[0037] It should be noted that the support frame 6 provides support for the lifting mechanism 7 and the sealing mechanism 8. Conveyor belt 10 is the main channel for transporting cookies into packaging bags 11 after they have been weighed and for subsequent packaging. It transports the packaging bags 11 containing cookies from the weighing position to subsequent packaging processes, such as heat sealing and cutting. The guide plate 12 guides and positions the packaging bags 11 transported on conveyor belt 10. The packaging bags 11 are containers used to package the cookies.

[0038] like Figure 5 As shown, the lifting mechanism 7 includes a second motor 71, which is fixedly connected to the upper surface of the support frame 6. The output end of the second motor 71 is fixedly connected to a threaded rod 72. The outer circumference of the threaded rod 72 is threadedly connected to a support seat 74. Two limiting rods 73, distributed front and rear, are slidably connected to the left side of the support seat 74. The limiting rods 73 are fixedly connected to the left side of the inner cavity of the support frame 6. The inside of the support seat 74 is movably connected to a sealing mechanism 8.

[0039] It should be noted that motor 71 is the power source for the lifting mechanism 7, driving the threaded rod 72 to rotate and providing power for the lifting movement of the sealing mechanism 8. This allows the sealing mechanism 8 to precisely adjust its height position according to the requirements of the packaging process, adapting to the needs of different sized packaging bags 11 and packaging procedures. The limiting rod 73 restricts the movement direction of the support base 74, ensuring it can only move linearly along the axial direction of the threaded rod 72. This prevents the support base 74 from shifting or wobbling during movement, ensuring the stability and positional accuracy of the sealing mechanism 8 during lifting. The support base 74 is the mounting platform for the sealing mechanism 8, supporting all its components.

[0040] like Figure 6 As shown, the edge sealing mechanism 8 includes a fixed frame 81, which is fixedly connected to the middle of the upper surface of the support base 74. A motor 82 is fixedly connected to the upper surface of the fixed frame 81. A gear 83 is fixedly connected to the output end of the motor 82. Two toothed plates 84 distributed in front and behind are meshed on the outer periphery of the gear 83. A connecting block 85 is fixedly connected to the lower surface of the opposite side of the two toothed plates 84. A heat sealing plate 88 is fixedly connected to the lower surface of the connecting block 85.

[0041] It should be noted that the mounting bracket 81 provides an installation platform for the motor 82. The motor 82 is the driving source for the movement of the heat-sealing plate 88 in the sealing mechanism 8, driving the gear 83 to rotate and providing power for the opening and closing of the heat-sealing plate 88. The function of the gear 83 is to convert the rotational motion of the motor 82 into the linear motion of the gear plate 84. Through meshing transmission with the gear plate 84, the synchronous and opposite movements of the two gear plates 84 drive the opening and closing of the heat-sealing plate 88. The connecting block 85 transmits the linear motion of the gear plate 84 to the heat-sealing plate 88. The heat-sealing plate 88 is equipped with a heating element. When the two heat-sealing plates 88 are closed, they can heat and pressurize the opening of the packaging bag 11, melting and bonding the plastic material of the packaging bag 11 together, thus sealing the packaging bag 11 and ensuring the airtightness and freshness of the cookies inside the packaging.

[0042] like Figure 6 As shown, sliders 87 are fixedly connected to both the front and rear sides of the heat-sealing plate 88, and slide rods 89 are fixedly connected to both the front and rear sides of the inner cavity of the support base 74. Slider 87 is slidably connected to the outer periphery of slide rod 89. Two limiting blocks 86 distributed in the front and rear are fixedly connected to the lower surface of the fixing frame 81. The opposite sides of the two toothed plates 84 are slidably connected to the opposite sides of the two limiting blocks 86.

[0043] It should be noted that the function of slider 87 is to guide and restrict the movement direction of heat-sealing plate 88, ensuring that heat-sealing plate 88 can only move linearly along the axial direction of slide rod 89 during opening and closing. This guarantees the smoothness and positional accuracy of heat-sealing plate 88's movement and prevents it from shifting or wobbling during movement, which would affect the heat-sealing quality. The function of limit block 86 is to limit the movement range of toothed plate 84, preventing it from exceeding the set stroke range during movement. This ensures the accuracy and safety of toothed plate 84's movement and also provides some guidance for its movement.

[0044] The working principle of this invention is as follows: After the automatic cookie conveyor packaging machine is started, motor 31 begins to run, driving drive shaft 32 and brush roller 13 to rotate. Drive shaft 32, through frictional contact with conveyor belt 2, causes conveyor belt 2 to start running, thereby moving the cookies on it forward. At the same time, brush roller 13 cleans the lower surface of conveyor belt 2, removing debris, dust, and other impurities that have accumulated on conveyor belt 2 during production. Vacuum adsorber 14 generates negative pressure, adsorbing cookie particles or light impurities inside brush roller 13, and directly discharging these debris into collection box 15. Cookie debris and packaging waste that fall from conveyor belt 2 or deviate from their position during transport will automatically slide towards the center along the inclined upper surface of guide block 9 and fall into collection box 15 for easy subsequent centralized cleaning.

[0045] When the cookies are conveyed to the measuring mechanism 4, the measuring device 41 accurately measures the weight or quantity of the cookies placed on the tray 44 and feeds the measurement data back to the equipment's control system in real time. Based on the measurement result, the electric push rod 42 extends and retracts, pushing the slider 43 to slide on the lower right side of the tray 44, causing the tray 44 to tilt. During the tilting process, the guide block 45 guides the cookies to slide smoothly into the packaging bag 11 on the lower conveyor belt 10.

[0046] The packaging bag 11 containing cookies is transported from the metering position to the subsequent packaging process position by the conveyor belt 10. At this time, the motor 71 starts to run, driving the threaded rod 72 to rotate. The support base 74 moves linearly along the axial direction of the threaded rod 72, thereby driving the sealing mechanism 8 to rise and fall to the designated height position. When the packaging bag 11 reaches the sealing position, the motor 82 starts to run, driving the gear 83 to rotate. The gear 83 meshes with the toothed plate 84, and the synchronous reverse movement of the two toothed plates 84 drives the heat sealing plate 88 to open and close through the connecting block 85. When the two heat sealing plates 88 close, they heat and pressurize the opening of the packaging bag 11, causing the plastic material of the packaging bag 11 to melt and stick together, thus sealing the packaging bag 11 and completing the cookie packaging process.
