Description

A fully automatic bag folding machine

Technical Field

The utility model relates to the technical field of bag folding, in particular to a full-automatic bag folding machine.

Background Art

There are many types of plastic bags widely used in the market, such as fresh-keeping bags, garbage bags, and plastic bags with handles commonly used for buying vegetables in the vegetable market, etc.

Some plastic bags need to be larger due to different application fields or the requirements of the containing capacity. Such large-capacity plastic bags cause great inconvenience in packaging and transportation. Therefore, such plastic bags need to be folded during production to reduce the volume of the bag for easy packaging and transportation. Moreover, some bags are very large (such as large garbage bags). During the production process, these large plastic bags need to be folded many times for easy packaging and transportation.

Manufacturers mainly use manual folding, which is inefficient. They also use mechanical folding. The current mechanical folding equipment is mainly single-channel folding, which can only fold one bag at a time. During the folding process, some components are in a waiting state, and bags on the conveyor belt are prone to accumulation.

Please refer to Figures 1-3. The utility model provides a technical solution: a fully automatic bag folding machine, including: a cabinet 1, a feeding conveyor belt 4, a feeding conveyor belt 22, two servo slides 1 5 arranged side by side, a primary folding motor 10, two servo slides 2 13, a secondary folding motor 17, two servo slides 3 19, and a feeding mechanism;

An operating table 2 is provided on the upper surface of the cabinet 1, a supporting frame 3 is provided on the upper side of the operating table 2, the loading conveyor belt 4 and the unloading conveyor belt 22 are respectively arranged on the left and right sides of the lower surface of the operating table 2, a through groove is horizontally opened on the middle left side of the operating table 2, the two servo slides 5 are arranged in the middle and left parts of the upper surface of the supporting frame 3, and an "n"-shaped mounting frame 6 is horizontally installed on the slide saddles of the two servo slides 5, and a mobile clamping mechanism is symmetrically installed on the lower sides of both ends of the mounting frame 6. The one-time folding motor 10 is installed on the front and rear parts of the left side of the upper surface of the operating table 2, and a folding shaft 11 is connected to the right side of the output shaft of the one-time folding motor 10. A one-time folding pressure plate 12 is provided on the outer wall of the two folding shafts 11, and the through groove is located between the two folding shafts 11. The two servo slides 2 13 are installed at the front and rear ends on the left side of the upper surface of the operating table 2, and the moving direction of the servo slide 2 13 is perpendicular to the moving direction of the servo slide 1 5. The slide saddles of the two servo slides 2 13 are both provided with push plates 14. The secondary folding motor 17 is installed at the middle right position of the front and rear side walls of the operating table 2. The output shaft of the secondary folding motor 17 is connected with a secondary folding pressure plate 18. The two servo slides 3 19 are installed at the front and rear ends on the right side of the upper surface of the operating table 2. The moving direction of the servo slide 3 19 is parallel to the moving direction of the servo slide 1 5. The slide saddle of the servo slide 3 19 is connected with a push plate 27. The pushing and unloading mechanism is located at the middle right of the upper surface of the operating table 2, and the pushing and unloading mechanism corresponds to the position of the unloading conveyor belt 22. The above servo slides, cylinders and other components adopt existing technologies, and the accessories required in the use process, such as air pumps, air supply pipelines, etc., are configured accordingly during use, which will not be repeated here.

Analysis of the above content: Before use, the following working mode is set for the above structure in advance (using the existing technology of controlling motors, cylinders and other power equipment, which will not be repeated here): the bag to be folded is placed on the feeding conveyor belt 4, and the feeding conveyor belt 4 is a plurality of unit conveyor belts arranged in sequence, and there are intervals between the unit conveyor belts. The width of the feeding conveyor belt 4 is not less than the width of the bag to be folded, and a lifting mechanism is set on the lower right side of the feeding conveyor belt 4 (not shown in the figure, a cylinder can be used, and a push rod is installed on the upper side of the telescopic end of the cylinder), and the lifting mechanism is located between the two middle unit conveyor belts, and the position of the lifting mechanism corresponds to the through slot. When the bag to be folded is transported to the lifting mechanism on the feeding conveyor belt 4, the lifting mechanism pushes it up, so that the middle part of the bag to be folded is lifted up and passes through the through slot and rises (the lateral length of the upper end of the lifting mechanism is less than the lateral length of the bag to be folded, and the lateral length of the bag to be folded is not greater than the lateral length of the through slot).

The middle part of the bag to be folded rises and reaches the height of the mobile clamping mechanism, and the servo slide 1 5 drives the mounting frame 6 to be centered, and the mobile clamping mechanisms at both ends clamp the left and right ends of the bag to be folded, and then the servo slide 1 5 moves the mounting frame 6, the mobile clamping mechanism and the clamped bag to be folded to one side of the folding assembly line (hereinafter, the movement of the bag to be folded to the front side of the folding assembly line is taken as an example), after the mounting frame 6 and the mobile clamping mechanism move, the bag to be folded is folded in half for the first time to obtain a folded bag, at which time the front end of the folded bag is against the servo slide 2 13 to prevent movement during folding, and at this time the folding assembly line on the other side is in a state of waiting for the next bag to be folded.

On the folding assembly line, first, the primary folding motor 10 drives the folding shaft 11 and the primary folding plate 12 on the folding shaft 11 to fold the primary folding bag to obtain a secondary folded bag, and the primary folding plate 12 is reset. At this time, the left edge of the secondary folded bag is supported on the push plate 14, and the servo slide 2 13 pushes the push plate 14 and the secondary folded bag to move to the right until the middle of the secondary folded bag reaches the output shaft of the secondary folding motor 17. At this time, the right end of the secondary folded bag is against the servo slide 3 19 to prevent movement during folding, and the output shaft of the secondary folding motor 17 drives the secondary folding plate 18 to flip over, fold the secondary folded bag to obtain a triple folded bag, and the secondary folding plate 18 is reset.

The servo slide 3 19 pushes the triple-folded bag to move backward, so that the triple-folded bag reaches the middle position of the operating table 2, and pushes the unloading mechanism to push the triple-folded bag to the unloading conveyor belt 22 for unloading. Since this solution is mainly for plastic bags, it is not easy to rebound after folding, and the folded state can be maintained after folding.

Embodiment 2:

Please refer to Figures 1-3. The utility model provides a technical solution based on Example 1: the mobile clamping mechanism includes a transverse telescopic cylinder 7 installed on the lower sides of both ends of the mounting frame 6, and the two transverse telescopic cylinders 7 are symmetrically installed. The telescopic ends of the transverse telescopic cylinders 7 are connected to the mounting plate, and the mounting plate is provided with a longitudinal telescopic cylinder 8 and two clamping rods 9. The two clamping rods 9 are arranged side by side, and one of the clamping rods 9 is connected to the telescopic end of the longitudinal telescopic cylinder 8.

Analysis of the above content: The transverse telescopic cylinder 7 can drive the mounting plate on its telescopic end to move, so that the mounting plate moves toward the raised position in the middle of the bag to be folded. At this time, the two clamping rods 9 are respectively located on the upper and lower sides of the raised position in the middle of the bag to be folded. One of the clamping rods 9 is in a fixed state, and the other clamping rod 9 is connected to the telescopic end of the longitudinal telescopic cylinder 8. The longitudinal telescopic cylinder 8 is also installed on the mounting plate. The telescopic end of the longitudinal telescopic cylinder 8 can push the clamping rod 9 on it to approach the other fixed clamping rod 9 to achieve clamping. After the clamping moves to a folding assembly line, the two clamping rods 9 are opened, and the transverse telescopic cylinder 7 drives the mounting plate and the longitudinal telescopic cylinder 8 and clamping rod 9 thereon to detach from the bag to be folded.

Embodiment three:

Please refer to Figures 1-3. The utility model provides a technical solution based on Example 1: the front and rear sides of the left side wall inside the support frame 3 are connected with a downward pressure cylinder 15, and the lower side of the telescopic end of the downward pressure cylinder 15 is connected with a pressure rod 16, and the pressure rod 16 extends to the right, and the two folding shafts 11 are located between the two pressure rods 16.

Analysis of the above content: the telescopic end of the pressing cylinder 15 can drive the pressure rod 16 to move up and down. When the servo slide 15 moves to one side of the folding assembly line with respect to the mounting frame 6, the mobile clamping mechanism and the bag to be folded, the telescopic end of the pressing cylinder 15 drives the pressure rod 16 to be lifted up, and the bag to be folded moves from the lower side of the pressure rod 16. When the bag to be folded (the bag to be folded once) is moved into place, the telescopic end of the pressing cylinder 15 drives the pressure rod 16 to descend, and the pressure rod 16 is pressed on the middle part of the bag to be folded. Then, the bag to be folded is folded and is pressed down by the pressure rod 16. When the bag is folded, it can be stable and not easy to shift. After folding, the telescopic end of the pressing cylinder 15 drives the pressure rod 16 to be slightly lifted up to avoid obstruction to the movement of the bag. After the bag is completely moved away, the telescopic end of the pressing cylinder 15 drives the pressure rod 16 to be lifted up and reset.

Embodiment 4:

Please refer to Figures 1-3. The utility model provides a technical solution based on the first embodiment: the upper surface of the operating table 2 is provided with a groove for accommodating the folding shaft 11, the primary folding plate 12, and the secondary folding plate 18.

Analysis of the above content: According to the use requirements, the sink is convenient for accommodating the folding shaft 11, the primary folding plate 12, and the secondary folding plate 18 to avoid obstruction to the movement of the bag.

Embodiment five:

Please refer to FIGS. 1-3 . The utility model provides a technical solution based on the first embodiment: a rotary pressing motor 20 is installed on the push plate 27 , and a pressure strip 21 is connected to the output shaft of the rotary pressing motor 20 .

Analysis of the above content: The overall thickness of the three-fold bag is relatively high and it is easy to rebound. After the secondary folding plate 18 is folded, the rotating pressing motor 20 drives the pressure bar 21 to rotate and press on the three-fold bag, making the three-fold bag not easy to rebound and spread.

Embodiment six:

Please refer to Figures 1-3. The utility model provides a technical solution based on Example 1: two limit grooves 26 are horizontally opened on the right side of the upper surface of the operating table 2, and the two limit grooves 26 are arranged in parallel front and back. A blocking telescopic cylinder (not shown in the figure) is arranged on the lower side of the limit groove 26, and a blocking bar (not shown in the figure) is connected to the upper side of the telescopic end of the blocking telescopic cylinder. The blocking bar is located in the limit groove 26, and the two limit grooves 26 correspond to the front and rear end edge positions of the unloading conveyor belt 22 respectively.

Analysis of the above content: When the blocking bar in the front limiting groove 26 is extended under the push of the blocking telescopic cylinder, the blocking bar has a blocking effect on the triple-folded bag, preventing the triple-folded bag from moving too far due to inertia and being difficult to reach the unloading conveyor belt 22. When the triple-folded bag is in place, the telescopic end of the blocking telescopic cylinder drives the blocking bar to descend and retract into the limiting groove 26. The two limiting grooves 26 are respectively used to block the triple-folded bags on the two folding lines.

Embodiment seven:

Please refer to Figures 1-3. The utility model provides a technical solution based on Example 1: the pushing and unloading mechanism includes a servo slide four 23 installed horizontally on the operating table 2 through a bracket, and a unloading cylinder 24 is installed on the lower side of the slide saddle of the servo slide four 23, and a push plate three 25 is connected to the lower side of the telescopic end of the unloading cylinder 24.

Analysis of the above content: the initial position of the unloading cylinder 24 is at the left end, the telescopic end of the unloading cylinder 24 drives the push plate three 25 to descend, the push plate three 25 is stuck at the left end of the three-folded bag that has been in place, and the servo slide four 23 drives the unloading cylinder 24, the push plate three 25, and the three-folded bag to move, so that the three-folded bag is pushed onto the unloading conveyor belt 22.
