Description

Technical Field

[0001] The invention relates to the technical field of bagging and packaging, in particular to a bagging machine with a winding function and a use method thereof. Background Art

[0002] Towels are generally rolled up before being packed. When a towel is rolled up, its shape changes from a flat two-dimensional shape to a three-dimensional shape that is approximately cylindrical. This shape can be arranged more tightly in the storage space. Rolling can allow the towel to maintain its original shape to a certain extent. If it is folded and packed directly, multiple foldings may cause the towel to form deeper and difficult-to-recover wrinkles at the folds, affecting the appearance and usability of the towel. Rolling is a relatively gentle method with less distortion and squeezing of the towel fibers, and it is easier to restore to its original shape after opening. First, you need to choose suitable packaging materials, such as plastic bags, plastic wrap or special towel packaging bags, mainly for moisture-proof and long-term storage, and then put the rolled towels into the selected packaging bags.

[0003] Chinese patent CN113562277B proposes a towel packing machine that is easy to fix for towel processing, including a base, a controller, a packing box and a conveyor belt. The packing box and the controller are both arranged on the base, and the conveyor belt is arranged on the packing box. A discharge channel for the towels to enter is arranged in the packing box, and a time delay device is arranged in the controller. It also includes: a fixing system, which is arranged on the base and is used to fix the base and the supporting surface, a winding system, which is arranged in the discharge channel and is used to wind up the towels entering the discharge channel, and a packaging system, which is arranged between the base and the packing box and is used to bag and package a plurality of rolled towels. By setting a discharge module, the position of the winding roller can be adjusted, and there is no need for the staff to manually remove the towels from the winding roller after the towels are rolled up.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patent cannot continuously load and rewind towels, and the working efficiency is low.

[0006] 2. This patent cannot continuously bag and pack towels, and cannot automatically seal and unload the bags after packing.

[0021] Step 2: Place the towel on the belt conveyor and convey it to the extension plate position through the belt conveyor. The output end of the second cylinder moves backward to drive the extension plate to move backward. One end of the towel falls from the extension plate, so that one end of the towel is close to the sliding rod. The output end of the first cylinder moves upward to drive the fixed block to move upward. The fixed block moves upward to make the fixed block leave the upper side of the special-shaped sliding base. The tension spring in the stretched state recovers, so that the special-shaped sliding base moves upward. The special-shaped sliding base moves upward to drive the sliding rod to move upward.

The output end of the first stepper motor rotates to drive the rotating bracket to rotate. The rotating bracket rotates to drive the fixed rod and the sliding rod on the special-shaped sliding base to rotate together, so that the towel is rolled up.

[0022] Step 3: The output end of the second linear module moves backward, driving the sliding rod and the fixed rod of the rotary winding assembly on the special-shaped bracket to move backward, so that the rolled towel moves to the horizontal plate position. The horizontal plate moves downward under the pressure of the towel, causing the spring to undergo elastic deformation, exerting a certain pressure on the rolled towel so that it will not easily spread out and lose the rolled state. The rolled towel continues to move backward from the horizontal plate to the rectangular pipe of the quantitative conveying device. The fixed rod and the sliding rod are located in the first slot of the rectangular pipe. The output end of the first linear module moves to the right, driving the fixed rod and the sliding rod of the rotary winding assembly to move to the right, so that the fixed rod and the sliding rod of the rotary winding assembly withdraw from the rolled towel, so that the rolled towel remains in the rectangular pipe.

[0025] Step 6: The output end of the fifth linear module moves backwards, driving the heightening bracket to move backwards. The heightening bracket moves backwards, driving the fourth cylinder to move backwards. The fourth cylinder moves backwards, driving the C-shaped plate to move backwards, so that the C-shaped plate and the rolled towel part thereon enter the opened packaging bag. The output end of the fourth cylinder moves in a direction away from the rolled towel, driving the C-shaped plate to move in a direction away from the rolled towel, releasing the clamped towel. The output end of the fourth linear module moves backwards, driving the transverse push plate to move backwards, pushing the released towel on the C-shaped plate into the opened packaging bag. The output shaft of the electric telescopic rod of the exhaust device on the middle side of the frame moves downwards, driving the pressure plate to move downwards, pressing the packaging bag that has been loaded with towels, and preliminarily exhausting the air in the packaging bag that has been loaded with towels. The external controller controls the quantitative conveying device, the bagging device and the exhaust device on the middle side of the frame to return to the initial state.

[0026] Step 7: The output end of the ninth linear module of the material moving assembly moves to the right, driving the moving frame to move to the right. The moving frame moves to the right, driving the multiple push plates on the moving frame to move to the right, pushing the packaging bag to the middle side of the fixed frame, pushing the packaging bag with towels loaded to the right side of the fixed frame, and the electric telescopic rod output shaft of the exhaust device on the right side of the frame moves downward, driving the pressing plate to move downward, pressing the packaging bag with towels loaded, and further exhausting the air in the packaging bag with towels loaded;

[0027] Step 8: The output shaft of the second stepper motor of the bag support assembly of the bag sealing device rotates to drive the main synchronous belt wheel to rotate. The main synchronous belt wheel rotates to drive the secondary synchronous belt wheel to rotate through the synchronous belt. The rotation of the synchronous belt causes the second slider on the left to move to the right, and the second slider on the right to move to the left, so that the support plates on the two second sliders move toward each other and move to the preset position to stop. The output end of the eighth linear module moves backward to drive the moving plate to move backward. The moving plate moves backward to drive the bag support assembly to move backward, so that the two support plates enter the packaging bag that has been loaded with towels. The output shaft of the second stepper motor rotates to drive the main synchronous belt wheel to rotate. The main synchronous belt wheel rotates The secondary synchronous belt wheel is driven to rotate by the synchronous belt, and the rotation of the synchronous belt causes the second slider on the left side to move to the left, and the second slider on the right side to move to the right, so that the support plates on the two second sliders move back to each other, move to the preset position and stop, and the packaging bag that has been loaded with towels is opened, and the output end of the eighth linear module moves forward to drive the moving plate to move forward a certain distance, and the moving plate moves forward to drive the bag-holding assembly to move forward a certain distance, so that the opened packaging bag that has been loaded with towels moves to the position of the plastic bag sealing machine, and the plastic bag sealing machine seals the packaging bag that has been loaded with towels, and the external controller controls the bag sealing device to return to the initial position;

[0028] Step nine: The output end of the ninth linear module moves to the right, driving the mobile frame to move to the right. The mobile frame moves to the right, driving multiple push plates on the mobile frame to move to the right, pushing the packaging bag to the middle side of the fixed frame, pushing the packaging bag that has been loaded with towels to the right side of the fixed frame, and pushing the sealed packaging bag to the right side of the fixed frame and letting it fall.

[0030] 2. The packaging bag is opened by the bag opening assembly of the bagging device, and the quantitative conveying device conveys a plurality of rolled towels to between the two C-shaped plates of the bagging device. The output end of the fourth cylinder moves toward the direction of the rolled towels, driving the C-shaped plate to move toward the direction of the rolled towels, and clamping the plurality of rolled towels between the two C-shaped plates.

[0032] 4. A packaging bag is arranged on the left side of the fixed frame of the material moving assembly, and a packaging bag loaded with towels is arranged on the middle side of the fixed frame.
