Technical Field

[0001] This invention relates to a paper bag handle manufacturing mechanism, specifically to a machine that integrates round and flat rope handles. Background Technology

[0002] Paper bags are widely used in various fields due to their recyclability and low cost. A typical paper bag consists of a bag body for carrying contents and two handles attached to the bag body, also known as handles. Currently available handles include round rope handles and flat rope handles, with different types produced according to different customer needs. However, in the production process, because the round rope handle making mechanism and the flat rope handle making mechanism are two separate machines, switching between them is very difficult, wastes worker time, and occupies a lot of space, making them inconvenient to use. Therefore, a handle making machine that integrates the round rope and flat rope making mechanisms is needed. Summary of the Invention

[0003] To address the above problems, this invention provides an integrated round and flat rope hand-handling machine, which combines a flat rope hand-handling mechanism and a round rope hand-handling mechanism on a single hand-handling machine. This facilitates the switching between round and flat ropes while reducing the size of the equipment and saving space.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a round rope and flat rope integrated hand-operated machine, comprising a base frame, on which a round rope hand-operated forming mechanism is provided, the round rope hand-operated forming mechanism being provided with a feeding wheel group and a round rope winding assembly from front to back, characterized in that the base frame is further provided with a flat rope hand-operated forming mechanism, the flat rope hand-operated forming mechanism being provided with a feeding roller group, a gluing roller group, a flattening rope assembly, and a discharging roller group from front to back;

[0005] It also includes a cutting mechanism shared by the round rope handle forming mechanism and the flat rope handle forming mechanism, as well as a handle reversing mechanism;

[0006] A frame is provided above the front of the base frame. The feeding roller group, the gluing roller group, the flattening rope assembly, and the discharge roller group are all located inside the frame, with the discharge roller group located above the conveying wheel group.

[0007] It also includes the upper paper belt pulley assembly and the lower paper belt pulley assembly, which are mounted on the frame.

[0008] The present invention is further configured such that the upper paper belt pulley group includes a fixed pulley and a reversing pulley disposed on the frame, the reversing pulley being located above the discharge roller group and used to guide the flat rope into the discharge roller group or guide the round rope into the winding round rope assembly.

[0009] The present invention is further configured such that a tensioning wheel is provided between the winding rope assembly and the discharge roller assembly, and the tensioning wheel abuts against the upper paper tape to keep it in a taut state.

[0010] The invention is further configured such that a connecting frame is provided on the base frame above the winding rope assembly, a connecting rod connected to the tensioning wheel is rotatably connected to the connecting frame, a locking plate is fixedly connected to one end of the connecting rod, a locking groove is provided on the end of the locking plate near the connecting rod, and a locking nut is provided on the locking plate through the locking groove, so that the locking plate can clamp the connecting rod by means of the locking nut.

[0011] The present invention is further configured such that the lower paper belt pulley assembly includes a central transfer wheel disposed at the bottom.

[0012] The invention is further configured such that a connecting frame is provided on the base frame above the winding rope assembly, a connecting rod connected to the tension wheel is rotatably connected to the connecting frame, a connecting plate is fixedly connected to one end of the connecting rod, and a slider is rotatably connected to the end of the connecting plate away from the connecting rod; a screw threadedly connected to the slider is also provided on one side of the base frame, and the screw is used to adjust the rotation angle of the tension wheel.

[0017] In summary, the beneficial effects of this invention are as follows:

[0018] This invention reduces the space occupied by adapting both the round rope handle forming mechanism and the flat rope handle forming mechanism to a single handle forming machine. During operation, both mechanisms have independent production routes. When producing round rope handles, the flat rope is cut, and the paper tape enters the round rope handle forming mechanism via the feed rollers. The round rope then adheres to the paper tape to form the handle, and is then conveyed to the cutting mechanism. When producing flat rope handles, the round rope is cut, and the flat rope enters the flattening rope assembly via the feed rollers. The paper tape is also guided into the flattening rope assembly to adhere to the flat rope. Finally, it is conveyed to the cutting mechanism via the discharge rollers to be cut and form the handle. Furthermore, the shared cutting mechanism and handle reversing mechanism reduce the overall size of the equipment.

[0019] Compared with existing technologies, this technology facilitates the switching between round rope and flat rope handle production for workers, improving production efficiency. It also reduces the size of the equipment, lowers production costs, and facilitates the maintenance of the round rope handle forming mechanism through the staggered arrangement of the round rope handle forming mechanism and the flat rope handle forming mechanism.

Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-7 As shown, a round rope and flat rope integrated hand-handling machine includes a base frame 1. A round rope hand-handling forming mechanism 2 is mounted on the base frame 1. The round rope hand-handling forming mechanism 2 is arranged from front to back as follows: a feeding wheel group 201, a round rope winding assembly 202, a cutting mechanism 7, and a hand-handling reversing mechanism 8. The base frame 1 is also equipped with a flat rope hand-handling forming mechanism 5. The flat rope hand-handling forming mechanism 5 is arranged from front to back as follows: a feeding roller group 501, a gluing roller group 502, a flattening rope assembly 503, a discharge roller group 504, and a cutting mechanism 7 and a hand-handling reversing mechanism 8 shared with the round rope hand-handling forming mechanism 2. The shared cutting mechanism 7 and hand-handling reversing mechanism reduce the size of the equipment and the area occupied, while making it more convenient for workers to change the type of hand-handling produced by the hand-handling machine.

[0030] A frame 6 is provided above the front of the base frame 1. The feeding roller group 501, the gluing roller group 502, the flattening rope assembly 503, and the discharge roller group 504 are all located inside the frame 6, with the discharge roller group 504 located above the front of the conveying wheel group 201. The flattening rope assembly 503 and the winding rope assembly 202 are staggered to create a certain distance between the two components, which facilitates the maintenance of the winding rope assembly 202 by the staff.

[0031] It also includes an upper paper belt pulley assembly 401 that conveys the upper paper belt to the discharge roller assembly 504 or the winding rope assembly 202, and a lower paper belt pulley assembly that guides the lower paper belt to the flattening rope assembly 503 or the feed wheel assembly 201.

[0032] In this embodiment, the upper paper belt pulley group 401 includes a fixed pulley 411 and a reversing pulley 421 disposed on the frame 301. The reversing pulley 421 is located above the discharge roller group 501 and is used to guide the flat rope into the discharge roller group 305 or to guide the round rope into the winding round rope assembly 202. It also includes a tensioning pulley 431 disposed between the winding round rope assembly 202 and the discharge roller group 504. The tensioning pulley 431 abuts against the upper paper belt to keep it in a taut state.

[0033] like Figure 4 As shown, a connecting frame 9 is provided on the base frame 1 above the winding rope assembly 202. A connecting rod 901, which is rotatably connected to the tension wheel 431, is rotatably connected to the connecting frame 9. A locking plate 902 is fixedly connected to one end of the connecting rod 901. A locking groove 903 is opened on the end of the locking plate 902 near the connecting rod 901. A locking nut 904 is also provided on the locking plate 902, which passes through the locking groove 903. The locking nut 904 can clamp the connecting rod 901 with the locking plate 902. By controlling the locking nut 904, the locking groove 903 can be adjusted. The spacing between the locking grooves 903 restricts the rotation of the connecting rod 901. When the locking nut 904 is loosened, the hole on the locking plate 903 and the connecting rod 901 are fitted with a clearance, allowing the connecting rod 901 to rotate. This allows the tension wheel 431 to be manually controlled to swing downwards to fit against the upper surface of the upper paper tape or swing upwards to fit against the lower surface of the upper paper tape. When the locking nut 904 is tightened, the spacing between the locking grooves 903 decreases, causing the locking plate 902 to deform and the hole on the locking plate 902 to press against the connecting rod 901, thereby clamping the connecting rod 901 and restricting its rotation.

[0034] In this embodiment, the lower paper conveyor roller assembly includes a central roller 412 disposed at the bottom.

[0035] In this embodiment, a discharge box 311 is provided at one end of the frame 301 near the cutting mechanism 7, and the discharge roller group 305 is rotatably mounted on the discharge box 311.

[0036] In this embodiment, a transition wheel 441 for supporting the upper paper tape is also provided between the reversing wheel 421 and the fixed wheel 411; the provision of the transition wheel 441 can prevent the upper paper tape from swinging up and down due to the excessive distance between the fixed wheel and the reversing wheel, and plays a supporting role for the upper paper tape.

[0037] In this embodiment, the flattened rope assembly 503 includes a conveyor chain 513, on which a plurality of guide shafts 523 are provided. An outer push plate 533 and an inner push plate 543 are slidably connected on every two guide shafts 523. A forming plate 553 is provided between the outer push plate 533 and the inner push plate 543.

[0038] Working principle: such as Figure 1 As shown, the present invention adapts the flat rope handle forming mechanism 3 to be installed on the base frame 1 simultaneously with the round rope handle forming mechanism 2, thereby reducing the size of the equipment and saving floor space. At the same time, compared with the prior art, it is not necessary to move the equipment when switching between the round rope handle and the flat rope handle, which facilitates the operation of the staff.

[0039] like Figure 5 As shown, when producing the round rope handle, the round rope and the lower paper tape pass under the frame 6, and are then conveyed to the winding round rope assembly 202 by the conveyor wheel group 201. They are then bonded together inside the winding round rope assembly 202, and then conveyed to the cutting mechanism 7 by the wheel at the end of the winding round rope assembly 202. At the same time, the upper paper tape is conveyed to the reversing wheel 421 by the fixed wheel 411, and then conveyed to the conveyor wheel at the rear end of the winding round rope assembly 202, and is located above the round rope. The conveyor wheel presses against the lower paper tape to clamp the round rope. Finally, it is cut into handles by the cutting mechanism 7 and conveyed to the next station by the handle reversing mechanism 8. During this process, the tensioning wheel 431 tilts downward and is in contact with the upper surface of the upper paper tape, thereby pressing the upper paper tape downward to ensure that the upper paper tape remains taut.

[0040] like Figure 6 As shown, when producing flat rope handles, the round rope is broken, and the two formed flat ropes are fed into the flattening rope assembly 503 through the feed roller group 501 on the frame 6. At the same time, the lower paper tape is kept taut by the intermediate roller 412 and enters the flattening rope assembly 503. During this process, it passes through the gluing roller group 502 to apply glue to the upper surface of the lower paper tape, and then adheres to the flat rope inside the flattening rope assembly 503. After passing through the reversing roller 421, the upper paper tape enters the discharge roller group 504 and the flattening rope assembly 503. Between 03 and 04, the flat rope is bonded to the surface of the lower paper tape within the discharge roller assembly 504, thereby clamping the flat rope in the middle to form a handle. Then, it is fed into the cutting mechanism 7 via the conveyor wheel at the end of the circular rope assembly 202. After being cut, it is sent to the next process by the handle reversing mechanism 8. The conveyor wheel can further squeeze the upper and lower paper tapes to ensure the adhesion is firm. At the same time, during this process, the tensioning wheel 431 tilts upward and fits against the lower surface of the upper paper tape, which plays a supporting and tensioning role.

[0041] When it is necessary to switch the production type of the handle rope, it is only necessary to cut the round or flat rope and change the conveying path of the paper tape. There is no need to move the equipment, which makes the operation of the staff more convenient and improves the work efficiency. At the same time, it reduces the space occupied by the equipment and saves the production cost of the equipment.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present invention should be included within the protection scope of the present invention.
