[0026] The technical solutions of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0027] See Figures 1 to 5, a fruit and vegetable net - covering device facilitating net - covering. The fruit and vegetable net - covering device includes: a core 3 and a clamping power mechanism 4; the core 3 is vertically arranged, and a net sleeve 5 can be sleeved on the core 3; there are multiple clamping power mechanisms 4, which are arranged in sequence along the axial direction of the core 3. The clamping power mechanism 4 includes an opening - closing device 41, a power device 42, and power rollers 43 vertically arranged on opposite sides of the core 3. The opening - closing device 41 can drive the power rollers 43 to approach or move away from the core 3, so that the power rollers 43 clamp or loosen the net sleeve 5. The power mechanism can drive the power rollers 43 to rotate, so that the net sleeve 5 moves downward. During the process of the net sleeve being sleeved on the core, at least one of the clamping power mechanisms clamps the core.

[0028] Through the above - mentioned setting, during net - covering, the clamping power mechanism 4 can clamp the core 3 and press the net sleeve 5 against the core 3. On the one hand, it plays a role in supporting the core 3. On the other hand, the clamping power mechanism 4 can also drive the net sleeve 5 to move downward; the power rollers 43 of the clamping power mechanism 4 below the lower end of the net sleeve 5 can be opened, facilitating the lower end of the net sleeve 5 to continue moving downward and then being clamped by the power rollers 43; during the whole net - covering process, there is no need to disassemble the core 3, improving the net - covering efficiency.

[0029] In this application, the core 3 plays a role in supporting the inner wall of the net sleeve 5; the clamping power mechanism 4 can be set to two, three, or other quantities. In this application, the clamping power mechanism 4 is set to two, which is beneficial to reducing the volume of the fruit and vegetable net - covering device; each clamping power mechanism 4 includes two of the above - mentioned power rollers 43; knurling can be provided on the outer side of the power rollers 43 to increase the friction between the power rollers 43 and the net sleeve 5; the opening - closing device 41 can drive the power rollers 43 to open and close. When the power rollers 43 are opened, the power rollers 43 move away from the core 3, and when the power rollers 43 are closed, the power rollers 43 approach the core 3.

[0030] The steps of the net - covering method are as follows:

[0031] Step a, the power rollers 43 of the uppermost clamping power mechanism 4 move away from the core 3, and the net sleeve 5 is sleeved on the upper end of the core 3; specifically, the power rollers 43 of the upper clamping power mechanism 4 are opened, a large gap is generated between the power rollers 43 and the core 3, an operator uses one hand to spread open the net mouth of the net sleeve 5, and sleeved the net mouth of the net sleeve 5 on the upper end of the core 3. At this time, the lower end of the net sleeve 5 moves between the power rollers 43 and the core 3, and the lower clamping power mechanism 4 still clamps the core 3 to support the core 3;

[0032] Step b, the power rollers 43 of the clamping power mechanism 4 approach the core 3 and clamp the net sleeve 5; specifically, the power rollers 43 of the upper clamping power mechanism 4 are closed to press the net sleeve 5 against the core 3. At this time, the net mouth of the net sleeve 5 is located between the upper and lower clamping power mechanisms 4;

[0033] Step c: The power roller 43 of the lower adjacent clamping power mechanism 4 moves away from the movement mechanism 3, and the power roller 43 of the clamping mesh sleeve 5 rotates, causing the lower end of the mesh sleeve 5 to continue moving downward along the movement mechanism 3. Specifically, the power roller 43 of the lower clamping power mechanism 4 opens, creating a large gap between the power roller 43 and the movement mechanism 3. The power roller 43 of the upper clamping power mechanism 4 rotates under the action of the power device 42, driving the mouth of the mesh sleeve 5 to move downward. When the lower end of the mesh sleeve 5 moves downward between the power roller 43 and the movement mechanism 3, the power roller 43 of the lower clamping power mechanism 4 closes and presses the mesh sleeve 5 against the movement mechanism 3.

[0034] Step d: Repeat Step b and Step c until all the power rollers 43 clamp the mesh sleeve 5. In this application, at this point, both the upper and lower clamping power mechanisms 4 clamp the mesh sleeve 5, that is, the mesh adding is completed.

[0035] As an implementation, the fruit and vegetable mesh sleeve device further includes a mesh sleeve counting and guiding mechanism 6, which is arranged above the movement mechanism 3. The mesh sleeve counting and guiding mechanism 6 includes: a first mounting plate 61, a mounting frame 62, a first guiding roller 63, a second guiding roller 64, an encoder 65, a controller (not shown in the figure), and an alarm (not shown in the figure). The first mounting plate 61 is arranged above the movement mechanism 3, and a first through hole 611 for the mesh sleeve 5 to pass through is provided on the first mounting plate 61. The mounting frame 62 is mounted on the first mounting plate 61. Both the first guiding roller 63 and the second guiding roller 64 are mounted on the mounting frame 62, and the mesh sleeve 5 can pass between the first guiding roller 63 and the second guiding roller 64 and drive the first guiding roller 63 and the second guiding roller 64 to rotate. The encoder 65 is mounted at the end of the first guiding roller 63 to calculate the number of rotation cycles of the first guiding roller 63. The encoder 65 is connected to the alarm through a controller (not shown in the figure). When the fruit and vegetable mesh sleeve device adds a mesh sleeve to the fruit and vegetable, the controller (not shown in the figure) calculates the used length of the mesh sleeve 5 according to the data of the encoder 65. When the used length of the mesh sleeve 5 is close to the total length of the mesh sleeve 5, the alarm emits an alarm to remind the operator to add a mesh sleeve.

[0036] Through the above settings, the fruit and vegetable mesh sleeve device has a function of warning about adding a mesh sleeve. When the mesh sleeve 5 is about to run out, the alarm can emit an alarm to remind the operator to add a mesh sleeve, preventing the fruit and vegetable mesh sleeve device from idling after the mesh sleeve 5 runs out.

[0037] Specifically, the first mounting plate 61 is horizontally mounted above the movement 3. There are two mounting brackets 62, which are mounted on the upper side of the first mounting plate 61. The first guide roller 63 and the second guide roller 64 clamp the mesh sleeve 5 to prevent the mesh sleeve 5 from shaking during the downward movement. At the same time, it can also provide a certain resistance to the downward movement of the mesh sleeve 5 to keep the mesh sleeve 5 in a tensioned state. Knurling can be provided on the first guide roller 63 and the second guide roller 64 to prevent slipping between the first guide roller 63 and the mesh sleeve 5 and increase the counting accuracy. The encoder 65 can be purchased on the market. The encoder 65 can calculate the number of turns of the first guide roller 63. According to the number of turns and the circumference of the first guide roller 63, the used length of the mesh sleeve 5 can be calculated. When the used length of the mesh sleeve 5 is close to the total length of the mesh sleeve 5, for example, when the ratio of the used length of the mesh sleeve 5 to the total length of the mesh sleeve 5 reaches 90%, the controller (not shown in the figure) controls the alarm to give an alarm.

[0038] As an implementation, the mesh sleeve counting and guiding mechanism 6 further includes a sliding seat 66, a second guide roller 64, and a spring 67. The sliding seat 66 is slidably connected to the mounting bracket 62 and can move closer to or away from the first guide roller 63 along the mounting bracket 62. The end of the second guide roller 64 is rotatably connected to the sliding seat 66. The spring 67 is connected to the sliding seat 66, and the spring 67 exerts a force on the sliding seat 66 towards the first guide roller 63 to clamp the mesh sleeve 5 between the first guide roller 63 and the second guide roller 64. In step a, manually push the second guide roller 64, and the second guide roller 64 separates from the first guide roller 63. Pass the mesh sleeve 5 through between the first guide roller 63 and the second guide roller 64 and set it on the upper end of the movement 3. After releasing the hand, the second guide roller 64 and the first guide roller 63 clamp the mesh sleeve 5.

[0039] Through the above settings, the second guide roller 64 and the first guide roller 63 can always stably clamp the mesh sleeve 5, enabling the mesh sleeve 5 to move downward stably. At the same time, it also ensures the accuracy of counting.

[0040] In this application, the axial direction of the spring 67 is parallel to the sliding direction of the sliding seat 66. One end of the spring 67 is connected to the mounting bracket 62, and the other end of the spring 67 is connected to the sliding seat 66. The second guide roller 64 can be manually pushed. When adding the mesh, when the second guide roller 64 is pushed away, the spring 67 shortens, and the sliding seat 66 moves away from the first guide roller 63. After releasing the hand, the spring 67 restores, and the spring 67 exerts a force on the second guide roller 64 towards the first guide roller 63 through the sliding seat 66, and the first guide roller 63 and the second guide roller 64 automatically clamp the mesh sleeve 5.

[0041] Specifically, in step a, the operator can first use one hand to open the mouth of the mesh sleeve 5, and use the other hand to push away the second guide roller 64, and then put the mesh sleeve 5 on the upper end of the movement 3.

[0042] As an implementation manner, two clamping power mechanisms 4 are provided. The power rollers 43 of the upper clamping power mechanism 4 are perpendicular to the power rollers 43 of the lower clamping power mechanism 4.

[0043] With the above settings, the stability of the movement 3 is increased.

[0044] In this application, the two power rollers 43 of the upper clamping power mechanism 4 clamp the movement 3 on the front and rear sides, and the two power rollers 43 of the lower clamping power mechanism 4 clamp the movement 3 on the left and right sides. When the fruit and vegetable netting device is netting, the movement 3 is clamped on all four sides, increasing the stability of the movement 3.

[0045] As an implementation manner, the opening and closing device 41 includes: a second mounting plate 411, a transmission belt 412, a first motor 413, and roller frames 414 provided on opposite sides of the movement 3; a second through hole 4111 for the netting to pass through is provided on the second mounting plate 411; the extending direction of the transmission belt 412 is parallel to the opening and closing direction of the power roller 43, and the transmission belt 412 is mounted on the second mounting plate 411 through a pulley 415; the first motor 413 is mounted on the second mounting plate 411; the roller frame 414 on one side of the movement 3 is connected to the upper side of the transmission belt 412, and the roller frame 414 on the other side of the movement 3 is connected to the lower side of the transmission belt 412, and the power roller 43 is rotatably connected to the roller frame 414; when adding the net, the first motor 413 drives the transmission belt 412 to rotate through the pulley 415, and the transmission belt 412 drives the roller frames 414 to approach or move away from each other, so that the power roller 43 approaches or moves away from the movement 3.

[0046] With the above settings, the first motor 413 can drive the roller frames 414 to approach or move away from each other through the pulley 415 and the transmission belt 412, thereby driving the power roller 43 to approach or move away from the movement 3.

[0047] In this application, a power device 42 can be installed on the roller frame 414, and the power device 42 can adopt a second motor; the second mounting plate 411 supports the transmission belt 412 through the pulley 415. Each opening and closing device 41 has two transmission belts 412, which are respectively arranged at both ends of the roller frame 414 to make the movement of the roller frame 414 more stable. The pulleys 415 of the two transmission belts 412 are driven by a transmission rod so that the two transmission belts 412 can run synchronously; the roller frames 414 of the opening and closing device 41 are installed on the upper and lower sides of the transmission belt 412. When the transmission belt 412 moves, the roller frames 414 can move in the same speed and in opposite directions. The power rollers 43 are symmetrically arranged on opposite sides of the movement 3. After the roller frames 414 approach under the action of the transmission belt 412, the clamping forces of the power rollers 43 on both sides of the movement 3 are basically equal, preventing the movement 3 from shifting due to uneven force.

[0048] As an implementation, in the opening and closing device 41 on the upper side, the roller frame 414 is arranged on the lower side of the second mounting plate 411; in the opening and closing device 41 on the lower side, the roller frame 414 is arranged on the upper side of the second mounting plate 411.

[0049] Through the above settings, the power rollers 43 of the opening and closing devices 41 on the upper and lower sides can be as close as possible, which is beneficial to reducing the length of the movement mechanism 3.

[0050] As an implementation, the opening and closing device 41 further includes guide rods 416. There are multiple guide rods 416, which are parallel to the transmission belt 412. The guide rods 416 are installed on the second mounting plate 411, pass through the roller frame 414 and are slidably connected to the roller frame 414.

[0051] Through the above settings, the movement stability of the roller frame 414 of the opening and closing device 41 is improved, and the roller frame 414 maintains linear movement during movement.

[0052] As an implementation, the movement mechanism 3 includes: a frame 31 and several support components 32; the support components 32 are arranged inside the power roller 43 to support the inner wall of the mesh sleeve 5. The support components 32 include a base 321 installed on the frame 31, and several support rollers 322 rotatably connected to the base 321. The several support rollers 322 are arranged from top to bottom and are arranged along the inner side of the power roller 43.

[0053] Through the above settings, first, the support rollers 322 can reduce the resistance of the movement of the mesh sleeve 5; the support rollers 322 are arranged along the inner side of the power roller 43. On the one hand, it can increase the contact area between the mesh sleeve 5 and the power roller 43 to prevent the power roller 43 from slipping. On the other hand, when the power roller 43 clamps the movement mechanism 3, it can prevent the movement mechanism 3 from moving up and down.

[0054] In this application, the movement mechanism further includes several idler pulleys 33 rotatably connected to the frame 31. The idler pulleys 33 support the inner wall of the mesh sleeve 5 to further reduce the resistance of the movement of the mesh sleeve 5; the support rollers 322 are arranged along the inner wall of the power roller 43, so that a groove adapted to the power roller 43 is formed on the outer side of the support component 32. When the power roller 43 clamps the movement mechanism 3, the inner side of the power roller 43 is embedded in the groove, and when the power roller 43 rotates, the movement mechanism 3 is not easy to move up and down.
