Description

Technical Field

[0001] This invention relates to the field of packaging machinery, and in particular to a semi-automatic fruit bagging machine. Background Technology

[0002] During their growth, fruits are susceptible to damage from birds, pests, sun and rain, tree branch scratches, and environmental pollution. Therefore, people often bag fruits during their growing season to improve their quality. Bagging helps maintain suitable temperature and humidity, increases sweetness and size, and enhances surface gloss.

[0003] Currently, most fruit farmers use the most primitive bagging method, which involves carrying rolls of plastic bags, twisting the opening open by hand, tearing individual plastic bags to place over the fruit, and then securing the opening with wire. This traditional method is time-consuming, labor-intensive, inefficient, and very inconvenient to carry and use the plastic bags and wire. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a semi-automatic fruit bagging machine that facilitates the carrying and orderly discharge of plastic bags and metal wires, allowing users to quickly and conveniently perform fruit bagging operations.

[0005] This invention adopts the following technical solution: a semi-automatic fruit bagging machine, including a front cover, a rear cover, and a carrying strap. The front and rear covers are detachably installed as a single unit. The carrying strap is attached to either the front or rear cover for user carrying. The front and rear covers form a storage space, within which a bag feeding mechanism, a bag supporting mechanism, and a yarn feeding mechanism are installed.

[0006] The bag feeding mechanism includes a bag placement space, a bag feeding motor, a front roller shaft, a rear roller shaft, a front rubber roller, and a rear rubber roller. The front and rear rubber rollers are arranged in pairs and located at the top, while the front and rear roller shafts are arranged in pairs and located in the middle. The bag placement space is located at the bottom for placing rolled bags. The rolled bags pass sequentially between the front and rear roller shafts and between the front and rear rubber rollers to extend upwards. The bag feeding motor drives the front and rear roller shafts and the front and rear rubber rollers to rotate, thereby conveying the rolled bags upwards. A stepper button is provided on the front or rear cover to control the start of the bag feeding motor. The bag feeding motor is controlled by a single-point stepper button, causing the front and rear rubber rollers to rotate one revolution. The circumference of the front and rear rubber rollers corresponds to the length of a single bag. A detection sensor is also provided at the bag outlet position above the front and rear covers. The detection sensor is used to detect whether the rolled bag has been conveyed to the correct position. When the position is reached, the detection sensor sends a feedback signal to stop the bag feeding motor.

[0007] The bag-supporting mechanism is located above the bag-feeding mechanism. It includes a left swing arm and a right swing arm. Both the left and right swing arms have silicone adhesive heads. The left and right swing arms are driven to close or separate by the driving component. When the roll bag is delivered to the position, the left and right swing arms are closed and then separated. The silicone adhesive heads stick to both sides of the roll bag and separate the bag opening.

[0008] The wire feeding mechanism includes a wire feeding motor, an aluminum wire roll, a right pinion, a left pinion, a right gear, and a left gear. The right and left gears are paired and located at the top, while the right and left pinions are paired and located in the middle. The aluminum wire roll is rotatably located at the bottom for winding the aluminum wire. The aluminum wire passes sequentially between the right and left pinions and between the right and left gears, extending upwards. Guide grooves are provided on the right and left pinions and the right and left gears to limit the aluminum wire and guide its transport during rotation. The wire feeding motor drives the right and left pinions and the right and left gears to rotate, thereby transporting the aluminum wire upwards. A stepper button controls the start of the wire feeding motor. The single-point stepper button controls the operation of the wire feeding motor, allowing the aluminum wire to be fed out from the top opening. The wire feeding motor also receives signals from the detection sensor. When the detection sensor detects that the roll bag has been delivered to the correct position, the detection sensor sends a feedback signal to stop the wire feeding motor.

[0009] As an improvement, the front cover and the rear cover are hinged on one side, and a buckle is provided on the other side for locking the two together; the front cover is an openable door structure, and the rear cover is the base for arranging the bag feeding mechanism, the bag supporting mechanism and the yarn feeding mechanism. The left and right mounting plates are provided on both sides inside the rear cover for mounting the bag feeding mechanism, the bag supporting mechanism and the yarn feeding mechanism.

[0010] As an improvement, one end of the front roller shaft and the rear roller shaft are equipped with meshing gears. The bag feeding motor is connected to the front roller shaft gear, which in turn drives the front roller shaft and the rear roller shaft to rotate in opposite directions. The other end of the front roller shaft is equipped with a small pulley, which is connected to a large pulley at the front rubber wheel via a synchronous belt. The other end of the front rubber wheel is equipped with a front gear, which meshes with a driving gear. The end of the rear rubber wheel is equipped with a rear gear, which meshes with a driven gear. The driven gear meshes with the driving gear. The bag feeding motor synchronously drives the front roller shaft and the rear roller shaft, as well as the front rubber wheel and the rear rubber wheel, to rotate.

[0011] As an improvement, the left and right swing arms are respectively hinged to two pivot pins fixed to the right mounting plate. The ends of the left and right swing arms are respectively hinged to connecting rods fixed to the slider. An iron core is installed inside the slider, and a spring is installed at the bottom of the slider. An electromagnet is installed in the middle of the spring. When energized, the electromagnet drives the slider to move downward, thereby causing the left and right swing arms to close. After de-energization, the left and right swing arms are reset and separated under the action of the spring.

[0012] As an improvement, pulleys are provided at the rear ends of the left pinion and the left gear. The two pulleys are connected by a fine-toothed synchronous belt for transmission. A guide wire is provided between the aluminum wire coil and the right pinion and the left pinion, as well as between the right pinion, the left pinion and the right gear and the left gear.

[0013] As an improvement, a wear-resistant ceramic ring is installed inside the conductor.

[0014] As an improvement, the aluminum wire coil is rotatably mounted on the right mounting plate via a screw. The screw provides installation limit on the outside of the aluminum wire coil, and a compression spring is also provided between the inside of the aluminum wire coil and the right mounting plate.

[0015] As an improvement, a battery slot is provided on the right mounting plate for the removable installation of a lithium battery. A circuit board is provided on the right mounting plate, which is electrically connected to the lithium battery, and a charging port is provided on the circuit board.

[0016] As an improvement, the front and rear rubber rollers are lined with inner linings, and the outer side of the inner linings is wrapped with a soft rubber layer. A bag-cutting blade is installed in the inner lining of the front rubber roller, and the blade of the bag-cutting blade protrudes from the soft rubber layer. The front rubber roller cuts the rolled bag when it rotates once.

[0017] As an improvement, a cutting blade is provided on the left gear, which cuts the aluminum wire when the left gear rotates once.

[0018] The beneficial effects of this invention are as follows: the structural design allows users to easily carry the machine on their backs, and when bagging fruit, the step button can be operated conveniently and quickly. The bag feeding mechanism and bag opening mechanism in the machine complete the single output of the rolled bag and the opening of the bag in an orderly manner, eliminating the need for users to open the bag in a tedious way, thus improving efficiency. The wire feeding mechanism delivers the aluminum wire required to wrap around the bag opening, which improves the convenience and efficiency of user operation as a whole. Attached Figure Description

[0033] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-13The image shows a specific embodiment of the semi-automatic fruit bagging machine of the present invention.This embodiment includes a front cover 5, a rear cover 2, and a carrying strap 1. The front cover 5 and the rear cover 2 are detachably installed as a single unit. The carrying strap 1 is attached to either the front cover 5 or the rear cover 2 for user carrying. The front cover 5 and the rear cover 2 form a storage space, in which a bag feeding mechanism, a bag supporting mechanism 16, and a yarn feeding mechanism 17 are installed. The bag feeding mechanism includes a bag placement space, a bag feeding motor 22, a front roller shaft 18, a rear roller shaft 19, a front rubber roller 12, and a rear rubber roller 13. The front rubber roller 12 and the rear rubber roller 13 are arranged in pairs and located at the top, while the front roller shaft 18 and the rear roller shaft 19 are arranged in pairs and located in the middle. The bag placement space is located at the bottom for inserting rolled bags 4. The rolled bags pass sequentially between the front roller shaft 18 and the rear roller shaft 19, and between the front rubber roller 12 and the rear rubber roller 13, extending upwards. The bag feeding motor 22... The front roller shaft 18 and rear roller shaft 19, front rubber roller 12 and rear rubber roller 13 are driven to rotate, thereby conveying the roll bag 4 upwards. A stepping button 9 is provided on the front cover 5 or the rear cover 2 to control the start of the bag feeding motor 22. The bag feeding motor 22 is controlled by the single-point stepping button 9 to make the front rubber roller 12 and rear rubber roller 13 roll one revolution. The circumference of the front rubber roller 12 and rear rubber roller 13 corresponds to the length of a single bag. A detection sensor is also provided at the bag outlet position above the front cover 5 and the rear cover 2. The detection sensor is used to detect whether the roll bag 4 has been conveyed to the correct position. When the position is reached, the detection sensor feeds a signal to stop the bag feeding motor 22. The bag supporting mechanism 16 is located above the bag feeding mechanism. It includes a left swing arm 1601 and a right swing arm 1603. Each arm has a silicone adhesive head 1605. A drive component drives the left swing arm 1601 and right swing arm 1603 to close or separate. When the roll bag 4 is delivered to the correct position, the left swing arm 1601 and right swing arm 1603 close and then separate, with the silicone adhesive heads 1605 adhering to both sides of the roll bag 4 and separating the bag opening. The wire feeding mechanism 17 includes a wire feeding motor 25, an aluminum wire roll 701, a right pinion 1701, a left pinion 1702, a right gear 1703, and a left gear 1704. The right gear 1703 and left gear 1704 are paired and located at the top, while the right pinion 1701 and left pinion 1702 are paired and located in the middle. The aluminum wire roll 701 is rotatably located at the bottom for winding the aluminum wire 10. The aluminum wire 10 passes sequentially through the right pinion 1701 and left pinion 1702. The aluminum wire 10 extends upward between the right gear 1703 and the left gear 1704, and wire grooves are provided on the right small gear 1701 and the left small gear 1702, and on the right gear 1703 and the left gear 1704 for limiting the aluminum wire 10 and guiding its conveying during rotation. The wire feeding motor 25 is used to drive the right small gear 1701 and the left small gear 1702, and the right gear 1703 and the left gear 1704 to rotate, thereby conveying the aluminum wire 10 upward. The step button 9 controls the start of the wire feeding motor 25. The wire feeding motor 25 is controlled by the single-point step button 9 to make the aluminum wire 10 be fed out from the upper opening. The wire feeding motor 25 receives the signal from the detection sensor. When the detection sensor detects that the roll bag 4 has been conveyed to the correct position, the detection sensor feeds back a signal to make the wire feeding motor 25 stop.

[0035] In use, the invention involves pre-positioning the roll bag 4 and aluminum wire 10 into the corresponding positions of the bagging machine, i.e., placing the roll bag 4 in the bag-laying space, which can be a cylindrical cavity formed on the left mounting plate 14 and the right mounting plate 15. An open opening is then formed on one side of the left mounting plate 14 for loading and replacing the roll bag 4. The end of the roll bag 4 extends upward from between the front roller shaft 18 and the rear roller shaft 19, and between the front rubber wheel 12 and the rear rubber wheel 13. The matching roller shafts and rubber wheels limit the roll bag 4 and convey it upward when the rotation starts. The front roller shaft 18 and the rear roller shaft 19 are closer to the storage position of the roll bag 4, and when driven by the bag-feeding motor 22, they play a role in stably pulling out the roll bag 4. The front rubber wheel 12 and the rear rubber wheel 13 are set to be larger, making more contact with the roll bag 4, and relying on the properties of their soft rubber, they play a role in stably conveying the roll bag 4 and a certain degree of adhesion to open the bag. The circumference of the front rubber roller 12 and the rear rubber roller 13 are set to correspond to the individual length of the roll bag 4, so that one bag is output when the front rubber roller 12 and the rear rubber roller 13 complete one revolution, which facilitates the setting and structural coordination of the bagging machine. A main power switch 8 and a step button 9 are located on the front cover 5. The power switch 8 is connected to the lithium battery 23 and the circuit board 24. When the power switch 8 is turned on, the entire machine is powered on. Then, by pressing the single-point step button 9, the bag feeding motor 22 is started, which in turn drives the front roller shaft 18 and the rear roller shaft 19, as well as the front rubber roller 12 and the rear rubber roller 13, to rotate and output the roll bag 4. A detection sensor located at the bag outlet detects that the roll bag 4 has been output to the correct position and sends a feedback signal to stop the bag feeding motor 22. At this point, the front end of the roll bag 4 and the bag opening are positioned at the bag-supporting mechanism 16. Then, by activating the left swing arm 1601 and the right swing arm 1603 to close, the silicone adhesive head 1605 sticks to the outside of the roll bag 4. When the left swing arm 1601 and the right swing arm 1603 separate, the bag opening is separated. At this time, as long as there is a certain separation at the bag opening, the user can quickly unfold the opening of a single bag through the separation position, which is convenient for quickly and easily bagging fruits.

[0036] Similar to the output of the roll bag 4, the output of the aluminum wire 10 is achieved by the wire feeding mechanism 17, and both can be operated simultaneously by the stepping button 9 to improve efficiency. That is, the aluminum wire 10 is fitted onto the aluminum wire roll 701. When the aluminum wire 10 is pulled out, the aluminum wire roll 701 rotates to discharge the material. Removing the aluminum wire roll 701 allows for the replacement and addition of the aluminum wire 10. The end of the aluminum wire 10 passes upwards between the right pinion 1701 and the left pinion 1702, and between the right gear 1703 and the left gear 1704. The aluminum wire 10 is accommodated in the wire guide groove, forming a limit. During startup, the aluminum wire 10 is conveyed upwards. The right pinion 1701 and the left pinion 1702 are closer to the storage position of the aluminum wire 10, and when driven by the wire feeding motor 25, they play a role in stably pulling out the aluminum wire 10. The right gear 1703 and the left gear 1704 are larger, making more contact with the aluminum wire 10 and playing a role in stably conveying the aluminum wire 10. The circumference of the right gear 1703 and the left gear 1704 corresponds to the pull-out length of the aluminum wire 10, so that when the right gear 1703 and the left gear 1704 run one revolution, they can output a section of aluminum wire 10 suitable for wrapping around the bag opening. The start and stop of the wire feeding motor 25 are also controlled by the step button 9 and the detection sensor together to achieve the effect of orderly and synchronous output.

[0037] As an improved specific implementation, the front cover 5 and the rear cover 2 are hinged on one side, and a buckle 11 is provided on the other side for locking the two after they are closed; the front cover 5 is an openable door structure, and the rear cover 2 is the base for arranging the bag feeding mechanism, the bag supporting mechanism 16 and the yarn feeding mechanism 17. The left mounting plate 14 and the right mounting plate 15 are provided on both sides inside the rear cover 2 for mounting the bag feeding mechanism, the bag supporting mechanism 16 and the yarn feeding mechanism 17.

[0038] like Figure 1 , 2 As shown in Figure 3, the bagging machine can be carried by the user on their back via the shoulder strap 1, making it convenient to use at the fruit trees that need bagging. The shoulder strap 1 is connected to the ring seat 6 via the loop 3, allowing the user to position the output ports of the roll bag 4 and aluminum wire 10 upwards or downwards according to their usage habits (the figure shows the output port facing upwards), without affecting the use of the machine or the material output. The front cover 5, as a door structure, is hinged to allow it to rotate to the side to open the internal space. The bag feeding mechanism, bag supporting mechanism 16, and wire feeding mechanism 17 are located at the rear cover 2. The buckle 11 can be implemented using existing technology to lock the front cover 5 and the rear cover 2 on one side when they are closed. The left and right mounting plates 14 and 15 are used to properly set the shaft structure for rotation and to mount other components on the sheet material.

[0039] As an improved specific implementation, one end of the front roller shaft 18 and the rear roller shaft 19 is provided with a front roller shaft gear 1802 and a rear roller shaft gear 1901 that mesh and drive each other. The bag feeding motor 22 is connected to the front roller shaft gear 1802, thereby driving the front roller shaft 18 and the rear roller shaft 19 to rotate in opposite directions. The other end of the front roller shaft 18 is provided with a small pulley 1801, which is connected to a large pulley 1201 provided at the front rubber wheel 12 via a synchronous belt 1202. The other end of the front rubber wheel 12 is provided with a front gear 1203, which meshes with a driving gear 21. The end of the rear rubber wheel 13 is provided with a rear gear 1301 that meshes with a driven gear 20. The driven gear 20 meshes with the driving gear 21. The bag feeding motor 22 synchronously drives the front roller shaft 18 and the rear roller shaft 19, as well as the front rubber wheel 12 and the rear rubber wheel 13, to rotate.

[0040] like Figure 3 , 4 As shown in Figures 5, 6, and 7, the above structure allows the front roller shaft 18 and the rear roller shaft 19, as well as the front rubber wheel 12 and the rear rubber wheel 13, to rotate synchronously, thereby improving the limiting stability and conveying stability of the roll bag 4. The synchronous belt 1202 is wound around the large pulley 1201 and the small pulley 1801, thereby synchronizing the rotation of the front roller shaft 18 and the front rubber wheel 12. The meshing of the front roller shaft gear 1802 and the rear roller shaft gear 1901 synchronizes the relative reverse rotation of the front roller shaft 18 and the rear roller shaft 19. The sequential meshing of the front gear 1203, the driving gear 21, the driven gear 20, and the rear gear 1301 synchronizes the relative reverse rotation of the front rubber wheel 12 and the rear rubber wheel 13. Thus, the four parts have a strong conveying force under the drive of the bag feeding motor 22 to drive the roll bag 4 to output. There is no possibility of slippage. Through the design of the tooth ratio of each gear and pulley and the diameter ratio of the rubber roller and the rubber wheel, it can be ensured that the linear speed of the roller shaft edge is consistent with the linear speed of the rubber wheel edge.

[0041] As an improved specific implementation, the left swing arm 1601 and the right swing arm 1603 are respectively hinged to two pivot pins fixed to the right mounting plate 15. The ends of the left swing arm 1601 and the right swing arm 1603 are respectively hinged to the connecting rod 1602 fixed to the slider 1604. An iron core is provided inside the slider 1604, and a spring 1606 is provided at the lower part of the slider 1604. An electromagnet is provided in the middle of the spring 1606. When energized, the electromagnet drives the slider 1604 to move downward, thereby causing the left swing arm 1601 and the right swing arm 1603 to close. After de-energization, the left swing arm 1601 and the right swing arm 1603 are reset and separated under the action of the spring 1606.

[0042] like Figure 3 , 4As shown in Figures 5, 6, 8, 9, and 12, the pivot pin is the central rotating shaft structure. When the inner connecting rod 1602 moves, it drives the outer left swing arm 1601 and right swing arm 1603 to move, thereby realizing the closing and separating action. The action of the connecting rod 1602 is driven by the iron core and the electromagnet being energized. Specifically, the slider 1604 is connected to the spring 1606, and the lower end of the spring 1606 is fixed to the upper mounting platform on the inner side of the right mounting plate 15. By relying on the energization and de-energization, the slider 1604 realizes the reciprocating action of going down or up, thereby realizing the closing and separating of the left swing arm 1601 and right swing arm 1603.

[0043] As an improved specific implementation, pulleys are provided at the rear ends of the left pinion 1702 and the left gear 1704. The two pulleys are connected by a fine-tooth synchronous belt 1705 for transmission. A guide wire 703 for the aluminum wire 10 to pass through is provided between the aluminum wire coil 701 and the right pinion 1701 and the left pinion 1702, and between the right pinion 1701, the left pinion 1702 and the right gear 1703 and the left gear 1704. A wear-resistant ceramic ring is provided inside the guide wire 703.

[0044] like Figure 8 , 9 As shown in Figure 10, the above structure allows the left pinion 1702 and left gear 1704, and the right gear 1703 and left gear 1704 to rotate synchronously, thereby improving the limiting stability and conveying stability of the aluminum wire 10. The left pinion 1702 and left gear 1704, and the right gear 1703 and left gear 1704 are meshed, enabling synchronous relative reverse conveying of the aluminum wire 10. A fine-toothed synchronous belt 1705 is wound around two pulleys, synchronizing the rotation of the left pinion 1702 and left gear 1704. This ensures that the four parts, driven by the wire feeding motor 25, have a strong conveying force to output the aluminum wire 10, preventing slippage. Bearings are installed at the ends of all rotating rollers, rubber wheels, gears, and pulleys to improve rotational flexibility and reduce wear. A fixed plate 26 can be installed at the position of the four gear sets to reinforce the outer structure and provide a mounting base for the four gears. The wire feeding motor 25 can be mounted on the fixed plate 26. On the other hand, by setting two guide wires 703, the aluminum wire 10 is stably and orderly guided and conveyed at the tangent positions of the left pinion 1702 and left gear 1704, and the right gear 1703 and left gear 1704, thereby improving the smoothness of conveying; and wear-resistant ceramic rings are set in the guide wires 703 to ensure their service life under the condition of frequent wear.

[0045] As an improved specific implementation, the aluminum wire coil 701 is rotatably mounted on the right mounting plate 15 via a screw 7. The screw 7 is installed and limited on the outside of the aluminum wire coil 701, and a compression spring 702 is also provided between the inside of the aluminum wire coil 701 and the right mounting plate 15.

[0046] like Figure 8 , 9 As shown in Figure 10, a spiral column structure for screwing in the screw 7 can be provided on the right mounting plate 15. The aluminum wire coil 701 is fitted onto it and screwed inward by the screw 7, forming a certain structural constraint by resisting the compression spring 702. When it is necessary to replace the aluminum wire 10, the screw 7 can be loosened to quickly replace the aluminum wire coil 701.

[0047] As an improved specific implementation, a battery slot is provided on the right mounting plate 15 and a lithium battery 23 is detachably installed thereon. A circuit board 24 is provided on the right mounting plate 15. The circuit board 24 and the lithium battery 23 are electrically connected, and a charging port 2401 is provided on the circuit board 24.

[0048] like Figure 8 , 9 As shown, an integrated circuit board 24 and a lithium battery 23 are mounted on the outer side of the right mounting plate 15 to realize power supply and start / stop control of the machine. The machine itself is used outdoors, and a charging port 2401 is added for timely charging, or charging after returning indoors.

[0049] As an improved specific implementation, the interior of the front rubber roller 12 and the rear rubber roller 13 is lined with a liner 1211, and the outer side of the liner 1211 is wrapped with a soft rubber layer 1210. A bag-cutting blade 1212 is installed in the liner 1211 of the front rubber roller 12, and the blade of the bag-cutting blade 1212 is exposed in the soft rubber layer 1210. The front rubber roller 12 cuts the rolled bag 4 when it rotates one revolution.

[0050] like Figure 13 As shown, the front rubber roller 12 and the rear rubber roller 13 have similar structures and cooperate to limit and convey the roll bag 4. The inner liner 1211 provides a rigid structure and is installed with the shaft structure. The soft rubber layer 1210 provides better elasticity to press the roll bag 4 for conveying, and at the same time provides a certain degree of adhesion to the roll bag 4 for initial bag opening. A bag cutting blade 1212 is set at the front rubber roller 12, which can cut the roll bag 4 with one rotation, so that the user can quickly remove individual bags and save the extra bag tearing operation.
