Description

Technical Field

[0001] This application relates to the field of automated equipment, and in particular to a fully automated packaging machine with adjustable positioning. Background Technology

[0002] In automated packaging production, precise film positioning and stable delivery are key factors determining packaging quality. Existing fully automated packaging machines suffer from the following technical deficiencies: First, the film positioning mechanism lacks flexibility, mostly adapting only to single-sized components. When the width or size of the component changes, it's difficult to quickly adjust the film coverage position, leading to film misalignment and uneven film coverage after packaging, affecting product sealing performance and appearance. Second, the film lacks an effective tension adjustment mechanism during delivery, easily causing film stretching and deformation due to excessive tension, or film loosening and wrinkling due to insufficient tension, further reducing packaging efficiency and finished product yield. Third, the component fixing structures of some equipment are cumbersome to operate; for example, adjusting the position of the film reel and guide plate requires disassembling multiple fasteners, which is time-consuming and labor-intensive, failing to meet the demands of high-efficiency production.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses an adjustable positioning fully automatic packaging machine, referring to... Figure 1 The system includes an operating table 1, which provides an installation base for the equipment. An installation groove is provided in the middle of the operating table 1, and a conveyor belt assembly 2 is laid in the installation groove. The output direction of the conveyor belt assembly 2 is consistent with the length direction of the operating table 1. During operation, the parts to be packaged are placed on the conveyor belt assembly 2, and the conveyor belt assembly 2 drives the horizontal and stable transmission, providing continuous material conveying for subsequent packaging processes.

[0032] It also includes a vertical plate 8, which is vertically fixed to the top surface of the operating table 1 and located on one side of the conveyor belt assembly 2. It serves as the mounting carrier for the centering positioning mechanism, which is used to precisely adjust the position of the film to ensure that the film covers the part to be packaged.

[0033] Reference Figure 1-3 The centering positioning mechanism is installed on the vertical plate 8 to precisely adjust the position of the film, ensuring that the film covers the central axis of the component to be packaged and avoids offset.

[0034] Specifically, it includes a support plate 15, which is horizontally arranged along the length of the operating platform 1. One end is fixed to the side wall of the vertical plate 8 facing the conveyor belt assembly 2 by bolts, and the other end has a through hole for a lead screw 17 extending along the width of the operating platform 1. The lead screw 17 is horizontally inserted into the through hole of the support plate 15, with one end extending above the conveyor belt assembly 2 and the other end welded with a handle 16. By rotating the handle 16, the lead screw 17 can be driven to rotate around its own axis. The outer wall of the lead screw 17 is provided with bidirectional threads. Furthermore, a nut 18 is fitted on each side of the support plate 15. The nut 18 is threadedly matched with the lead screw 17. When the lead screw 17 rotates to the target angle, tightening the nuts 18 on both sides of the support plate 15 can fix the lead screw 17 to the support plate 15 and prevent the lead screw 17 from shifting during the encapsulation process. The rotating plate 19 has a rectangular plate structure with a mounting hole in the center that matches the lead screw 17. It is connected by a key or fitted tightly to one end of the lead screw 17 that extends above the conveyor belt assembly 2 and can rotate synchronously with the lead screw 17.

[0035] Two round rods 20 are provided, which are horizontally installed at both ends of the rotating plate 19 by bearings and extend along the length of the operating table 1. The outer wall of the round rod 20 is provided with positioning grooves 22 distributed along its axis. The guide plate 21 has a disc-shaped structure and a through hole adapted to the round rod 20 is opened at the center. It is sleeved on the outer wall of the round rod 20 and fixed to the round rod 20 by fasteners 12. The guide plate 21 is used to guide and limit the film to prevent the film from shifting during the transmission process. Its position on the round rod 20 can be adjusted by the fasteners 12 to adapt to the packaged parts of different widths.

[0036] It also includes a rotating rod 9, which is horizontally inserted into a through hole at the top of the vertical plate 8. Both ends are rotatably connected to the vertical plate 8 via bearings. The outer wall of the rotating rod 9 is provided with positioning grooves 22 distributed along its axis. The film roll 10 is sleeved on the outer wall of the rotating rod 9 for sleeved film rolls. It is fixed to the rotating rod 9 by fasteners 12 and can rotate synchronously with the rotating rod 9. The motor 14 is fixed to the side wall of the vertical plate 8 by a motor bracket. Its output end is connected to one end of the rotating rod 9 via a coupling. During operation, the motor 14 drives the rotating rod 9 to rotate, which drives the film roll 10 to rotate synchronously. The unwinding speed is adjusted according to the transmission speed of the conveyor belt assembly 2 to achieve uniform and stable unwinding of the film.

[0037] Reference Figure 3 Fastener 12 is used to fix guide disc 21 and round rod 20, membrane reel 10 and rotating rod 9, and has quick adjustment and locking functions. It includes collar 121, which is annular in structure and sleeved on the outer wall of round rod 20 or rotating rod 9. Its inner wall is clearance-fitted with the outer wall of round rod 20 or rotating rod 9 and can move along the axis of round rod 20 or rotating rod 9. Channel 122 is opened radially on the side wall of collar 121 and penetrates the inner and outer walls of collar 121 to accommodate positioning ball 123 and spring 1. 24 and pull rod 126, the positioning ball 123 is made of metal and is set in the channel 122. Its diameter is slightly smaller than the inner diameter of the channel 122, and it can move radially in the channel 122. A part of the positioning ball 123 can extend out of the inner wall of the channel 122 and be inserted into the positioning groove 22 on the outer wall of the round rod 20 or rotating rod 9, so as to achieve the initial fixation of the collar 121 to the round rod 20 or rotating rod 9. The positioning groove 22 is an arc-shaped groove, evenly distributed along the axial direction of the round rod 20 or rotating rod 9, and is positioned with the positioning ball 126. 3. Adaptation: The position of the guide plate 21 or the membrane reel 10 is adjusted and locked by the cooperation of the positioning ball 123 with different positioning grooves 22. The circular plate 125 has a circular plate structure and is fixed to the outer wall of the collar 121 by bolts. It is coaxial with the channel 122. A through hole adapted to the pull rod 126 is opened at the center of the circular plate 125. One end of the pull rod 126 extends into the channel 122 and is welded and fixed to the positioning ball 123. The other end extends through the through hole of the circular plate 125 to the outside of the collar 121. The spring 124 is sleeved on the outer wall of the pull rod 126. One end is welded to the positioning ball 123, and the other end abuts against the inner wall of the circular plate 125. When the position needs to be adjusted, the pull rod 126 is pulled outward, which causes the positioning ball 123 to compress the spring 124 and disengage from the positioning groove 22. The collar 121 can then be moved along the axis of the circular rod 20 or the rotating rod 9. After adjusting to the target position, the pull rod 126 is released, and the positioning ball 123 is re-engaged into the positioning groove 22 under the elastic force of the spring 124, thus completing the fixation.

[0038] Reference Figure 1 It also includes an I-shaped mounting plate 3, which is I-shaped and fixed to the top surface of the operating table 1 by bolts, and spans the top surface of the conveyor belt assembly 2. The two sides of the I-shaped mounting plate 3 have support rod mounting holes along the width direction of the operating table 1. The first support rod 4 is horizontally inserted into the support rod mounting hole in the side recess of the I-shaped mounting plate 3, and its two ends are rotatably connected to the I-shaped mounting plate 3 by bearings. The pressure roller 5 is made of rubber and is coaxially sleeved on the outer wall of the first support rod 4. Its bottom surface is in clearance fit with the top surface of the conveyor belt of the conveyor belt assembly 2 (the clearance is slightly smaller than the total thickness of the part to be packaged and the film). When the part to be packaged carries the film under the pressure roller 5, the pressure roller 5 rotates synchronously under the action of friction to roll the film, ensuring that the film is flat and adheres to the surface of the part to be packaged, and eliminating wrinkles.

[0039] The second support rod 6 is horizontally inserted into the support rod mounting hole in the recess on the other side of the I-shaped mounting plate 3. Both ends are rotatably connected to the I-shaped mounting plate 3 through bearings. The auxiliary disk 7 is coaxially sleeved on the outer walls of both ends of the second support rod 6. The auxiliary disk 7 is used to guide and limit the film on both sides, further preventing the film from shifting laterally during transmission.

[0040] The hot pressing assembly 13 is installed on the top surface of the operating table 1, located downstream of the pressure roller 5 (in the transmission direction), and spans the top surface of the conveyor belt assembly 2. Its input end corresponds to the output end of the pressure roller 5. When the flattened film covers the part to be packaged and is transported to the bottom of the hot pressing assembly 13, the hot pressing assembly 13 heats and presses the film to complete the packaging operation.

[0041] The implementation principle of the adjustable positioning fully automatic packaging machine in this application embodiment is as follows: Preliminary adjustments are made based on the width of the component to be packaged and the film specifications.

[0042] Rotate the handle 16 to drive the lead screw 17 to move along the through hole of the support plate 15, adjust the rotating plate 19 to a suitable position above the conveyor belt assembly 2, then tighten the nuts 18 on both sides of the support plate 15 to fix the lead screw 17, pull the pull rod 126 of the fastener 12 outward to drive the positioning ball 123 to disengage from the positioning groove 22 of the round rod 20, move the guide plate 21 to a position matching the width of the part to be packaged, release the pull rod 126, and the positioning ball 123 will be inserted into the positioning groove 22 under the elastic force of the spring 124 to complete the fixing of the guide plate 21, rotate the rotating plate 19 to adjust the tilt angle of the guide plate 21, and preset the film conveying tension.

[0043] Pull the lever 126 of the fastener 12 to move the film roll 10 to the appropriate position on the rotating rod 9, ensuring that the film unwinding direction is consistent with the guiding direction of the guide plate 21. Release the lever 126 to complete the fixation. Set the output speed of the motor 14 according to the preset transmission speed of the conveyor belt assembly 2 to ensure that the film unwinding speed matches the conveying speed of the packaged item.

[0044] Based on the film material, the heating temperature and pressure of the hot pressing component 13 are set to ensure that the film can be effectively melted and sealed.

[0045] Automated packaging stage

[0046] The components to be packaged are placed one by one at the input end of the conveyor belt assembly 2, and the conveyor belt assembly 2 drives the components to be packaged to move at a constant speed along the length of the operating table 1 to the subsequent process.

[0047] Motor 14 drives the rotating rod 9 to rotate, which in turn drives the film reel 10 to rotate and unwind synchronously. After being guided by the guide plate 21, the film is precisely covered on the top surface of the component to be packaged. The guide plate 21 ensures that the tension of the film is stable during the film conveying process, without deviation or slack, through a preset tilt angle.

[0048] The component to be packaged, carrying the film, moves to the bottom of the pressure roller 5. The pressure roller 5 rotates synchronously under the action of friction to crush the film, eliminate film wrinkles, and make the film flat and adhere to the surface of the component to be packaged. At the same time, the auxiliary disk 7 guides and limits the film on both sides to further prevent the film from shifting.

[0049] After being flattened and pressed, the part to be packaged continues to move to the bottom of the hot pressing assembly 13. The heating module of the hot pressing assembly 13 heats the film to a molten state, and the pressurizing mechanism applies pressure simultaneously to make the film and the part to be packaged fit tightly together, thus completing the sealing and packaging. After the product is packaged, it moves to the output end with the conveyor belt assembly 2 to realize automated material collection.

[0050] During the specification switching phase, when it is necessary to change to a different specification of the packaged part, it is only necessary to repeat the adjustment steps of the equipment debugging phase: adjust the position of the lead screw 17 by turning handle 16, adjust the position of guide plate 21 and film roll 10 by fastener 12, and adjust the tilt angle and hot pressing parameters of rotating plate 19. The specification switching can be completed quickly without disassembling a large number of parts, making the operation efficient and convenient.
