Description

Technical Field

[0001] The present invention relates to the technical field of agricultural product packaging machinery, and particularly relates to a banana stem winding and bundling device for the post-treatment link of banana detaching. Background Art

[0002] Bananas are one of the main cash crops for the economic development of southern regions of China and are crucial for the income of banana farmers in hilly and mountainous areas. The banana bunches picked intact from the fields need to go through the detaching operation to obtain the banana hands that can be purchased by supermarket consumers daily. The main purpose of the detaching operation is to separate each banana hand on the banana bunch from the banana stem. After separation, the banana hands are successively subjected to cleaning, packaging, and transportation processes, and finally reach the hands of consumers.

In fact, the banana stem is rich in plant fibers and is an excellent raw material for composite materials and fiber products. The main reason for the banana stem to be discarded after detaching is that the surface of a single banana stem is relatively smooth, and there will be juice after cutting the banana stalk during detaching. It is inconvenient to carry a single banana stem, resulting in a large amount of banana stems being discarded and piled up, and it will rot and pollute the environment after a long time. Therefore, it is an urgent problem for banana farmers to uniformly pack and reuse the banana stems after banana detaching, avoid resource waste and environmental pollution caused by random discarding, and improve the economic value of banana stems.

Detailed implementation mode

[0027] The following is further described in detail in conjunction with the attached Figure 1-8 This invention will be further described in detail.

[0028] Embodiment 1:

[0029] As Figure 1-4 shown, a banana stem winding and bundling device for the post-treatment of banana combing includes a support 100, a vertical mounting plate 200 is fixedly connected to the support 100, a feeding port 201 for feeding the banana stem 600 is provided on the mounting plate 200, a side opening 202 communicating with the feeding port 201 is provided on one side of the feeding port 201, a winding ring 300 coaxial with the feeding port 201 is provided on one side of the mounting plate 200, a discharging port 301 is provided on the winding ring 300, the size of the discharging port 301 is adapted to the size of the side opening 202, a packing wheel 400 for fixing the packing belt roller 700 is provided on the outer side of the winding ring 300, a limiting mechanism 203 is provided on one side of the mounting plate 200 where the winding ring 300 is located, the winding ring 300 can rotate within the limiting mechanism 203, the limiting mechanism 203 includes a plurality of limiting wheels 2031 surrounding the winding ring 300, the cross-section of the limiting wheel 2031 is in the shape of "I", the limiting wheel 2031 is rotatably connected to the mounting plate 200, the outer edge of the limiting wheel 2031 abuts against the outer edge of the winding ring 300, and the outer edge of the winding ring 300 is embedded in the "I"-shaped groove of the limiting wheel 2031, so as to limit the winding ring 300 to rotate only within the annular space surrounded by the plurality of limiting wheels 2031, and a driving mechanism 500 for driving the winding ring 300 to rotate within the limiting mechanism 203 is provided on the mounting plate 200.

[0030] As Figure 2 shown, the driving mechanism 500 includes a synchronous belt motor 501 fixedly connected to the mounting plate 200 on the opposite side of the winding ring 300, and the synchronous belt motor 501 is arranged opposite to the side opening 202.

[0031] As Figure 1 , 2As shown, the rotating shaft of the synchronous belt motor 501 passes through the mounting plate 200 and is coaxially and fixedly connected to the synchronous belt driving wheel 502. A number of synchronous belt wheels 503 are provided on the outer edge of the winding ring 300 on the side close to the synchronous belt driving wheel 502. A synchronous belt 504 is drivingly connected between the number of synchronous belt wheels 503 and the synchronous belt driving wheel 502. The outer surface of the synchronous belt 504 abuts and rubs against the outer edge of the winding ring 300.

[0032] As Figure 2 shown, the cross-section of the synchronous belt wheel 503 in the first embodiment is "I"-shaped. Synchronous belt teeth meshing with the synchronous belt 504 are provided in the "I"-shaped groove of the synchronous belt wheel 503. The winding ring 300 is embedded in the "I"-shaped groove of the synchronous belt wheel 503, which can play a role in limiting the winding ring 300. At the same time, the outer surface of the synchronous belt 504 abuts and rubs against the outer edge of the winding ring 300, which plays a role in driving the winding ring 300 to rotate 360° in the annular space surrounded by the limiting wheel 2031 and the synchronous belt wheel 503.

[0033] As Figure 1 、 3 shown, the packing wheel 400 includes a packing wheel shaft 401. Necked studs are provided at both ends of the packing wheel shaft 401. One end of the packing wheel shaft 401 is screwed and fastened to the winding ring 300. An inner retaining ring 402 is fixedly connected to the side of the packing wheel shaft 401 close to the winding ring 300. An outer retaining ring 403 is sleeved on the stud at the end of the packing wheel shaft 401 far from the winding ring 300 and a locking nut is screwed.

[0034] Before the winding work starts, first insert the packing belt roller 700 wound with the packing belt into the packing wheel shaft 401, then sleeve the outer retaining ring 403 onto the stud and lock it with the locking nut. The inner retaining ring 402 and the outer retaining ring 403 clamp and limit the packing belt roller 700.

[0035] The number of synchronous belt wheels 503 is 2 - 3.

[0036] As Figure 4 shown, in the first embodiment, the number of synchronous belt wheels 503 is 3. The central angle (β) of the center of the winding ring 300 between two adjacent synchronous belt wheels 503 is greater than the central angle (α) at both ends of the discharge port 301 on the outer edge of the winding ring 300. This structure can avoid the situation that when the winding ring 300 rotates, the discharge port 301 is located outside two adjacent synchronous belt wheels 503, resulting in the stalling of the synchronous belt 504, and ensures that the synchronous belt 504 can drive the winding ring 300 to rotate stably and reliably.

[0037] The working process of the first embodiment is as follows: first, a single or multiple banana stems 600 are inserted into the feeding port 201 and the strapping tape on the strapping tape roller 700 is wound around the front end of the banana stem 600, the synchronous belt motor 501 is started, the synchronous belt motor 501 drives the synchronous belt driving wheel 502 to rotate and drives the synchronous belt 504 to rotate, the friction force of the synchronous belt 504 drives the winding ring 300 to rotate, the strapping tape roller 700 on the strapping wheel shaft 401 rotates synchronously with the winding ring 300 and wraps the strapping tape on the strapping tape roller 700 around the banana stem 600. The banana farmers simultaneously extend the banana stems 600 into the feeding port 201, and the strapping tape on the strapping tape roller 700 is spirally wound around the banana stems 600. After the strapping tape on the strapping tape roller 700 is wound to the tail of the banana stems 600, when the discharge port 301 of the winding ring 300 overlaps and aligns with the side opening 202 of the mounting plate 200, the synchronous belt motor 501 is controlled to stop, the strapping tape on the strapping tape roller 700 is cut off, and the packaged banana stems 600 are taken out from the overlapping portion of the discharge port 301 and the side opening 202.

[0038] When the banana stems 600 are relatively short, after the banana stems 600 are wound, the packing tape on the packing tape roller 700 may be cut off, and the packed banana stems 600 may be directly drawn out from the feeding port 201 .

[0039] Embodiment 2:

[0040] The difference between the second embodiment and the first embodiment lies in that the inner edge of the winding ring 300 is provided with inner teeth 302 along the circumferential direction, and the driving mechanism 500 for driving the winding ring to rotate is different.

[0041] like Figure 5-7 As shown, the driving mechanism 500 includes a first gear 510 and a second gear 511 respectively meshing with the inner teeth 302 of the winding ring 300, a driving motor 512 is fixedly connected to the mounting plate 200 on the opposite side of the first gear 510, and the rotating shaft of the driving motor 512 is coaxially fixedly connected to the first gear 510 and the driving gear 513, one end of the axle of the second gear 511 is rotatably connected to the mounting plate 200, and the other end is coaxially fixedly connected to the driven gear 514, and the driving gear 513 and the driven gear 514 are connected by a chain (not shown in the figure).

[0042] When the driving motor 512 is working, the driving motor 512 drives the driving gear 513 to rotate, and the driving gear 513 synchronously drives the first gear 510 to rotate. At the same time, the driving gear 513 also synchronously drives the driven gear 514 to rotate through the chain, and the driven gear 514 synchronously drives the second gear 511 to rotate; the first gear 510 and / or the second gear 511 are engaged with the inner teeth 302 of the winding ring 300, driving the winding ring 300 to rotate.

[0043] To improve the reliability of the driving gear 513 and the driven gear 514 through chain drive, the end of the axle of the second gear 511 away from the mounting plate 200 and the rotating shaft end of the driving motor 512 are respectively rotatably connected to a reinforcing plate 515, and a reinforcing rod 516 is fixedly connected between the middle of the reinforcing plate 515 and the mounting plate 200.

[0044] The first gear 510 and the second gear 511 of this embodiment are arranged opposite to the side opening 202.

[0045] As Figure 8 shown, the central angle (γ) of the first gear 510 and the second gear 511 with respect to the center of the winding ring 300 is greater than the central angle (α) at both ends of the discharge port 301 at the outer edge of the winding ring 300. Through this setting, it can be avoided that when the winding ring 300 rotates, the first gear 510 and the second gear 511 are both located inside the discharge port 301 of the winding ring 300, ensuring that at least one of the first gear 510 and the second gear 511 can mesh with the internal teeth 302 of the winding ring 300, enabling the winding ring 300 to rotate 360°.

[0046] The feeding port 201 is a circular or polygonal hole.

[0047] This device can not only be used for winding and bundling the banana stems 600 as described above, but also for bundling the banana bunches together with packaging materials after harvesting in the field. Since banana combs grow axially and circumferentially on the banana bunches, if a single banana bunch is not wound and bundled, the banana combs are likely to move due to centrifugal force during transportation, and then the fruits will collide and be damaged. After bundling the banana bunches with this device, the banana combs can be firmly tied to the banana stems or the banana bunch bodies, which is equivalent to "fastening a seat belt" for the banana combs, effectively reducing the vibration and damage caused by subsequent operations during picking.

[0048] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
