Description

Technical Field

[0001] The utility model relates to the field of fruit and vegetable net sleeves, in particular to a counting rectangular net box device for a fruit and vegetable net sleeve machine. Background Art

[0002] The frame of the existing fruit and vegetable net sleeve machine is usually of a rectangular structure. In the prior art, a circular disk is usually used for storing net sleeves in the fruit and vegetable net sleeve machine. For example, in the invention patent CN117441491A, there will be blank spaces at the four corners of the circular disk on the frame. The space at the four corners of the circular disk is small, making it difficult to install other components, which easily causes space waste. Moreover, the height and length of the circular disk can only be the same size, which is not conducive to changing the layout to reduce the height or length dimension, especially for net sleeves of different sizes. In addition, the circular disk in the above patent also lacks the statistics of the output length of the net sleeve, and users cannot timely discover the situation of insufficient net sleeves, resulting in a poor user experience. Summary of the Utility Model

[0003] The purpose to be achieved by the utility model is to provide a counting rectangular net box device for a fruit and vegetable net sleeve machine, which solves the problem of space waste caused by the existing structure for storing net sleeves, effectively improves the space utilization rate, and realizes the function of reminding when the net is lacking.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: A counting rectangular net box device for a fruit and vegetable net sleeve machine, including a rectangular net box for storing net sleeves. The rectangular net box is provided with a feed inlet, a discharge outlet, a driving roller and a guiding roller. The feed inlet allows the net sleeve with a set length and folded to enter the rectangular net box. The guiding rollers are arranged in pairs on both sides of the discharge outlet to form a guiding channel. The driving roller is located upstream of the guiding roller. The folded net sleeve passes through the driving roller and the guiding channel and is output from the discharge outlet. An alarm mechanism for obtaining the number of rotations of the driving roller or the guiding roller and capable of sending a reminder message is provided on the driving roller or the guiding roller.

[0005] After adopting the above technical scheme, the utility model has the following advantages: First, a rectangular net box is adopted, especially suitable for the frame of a rectangular-structured fruit and vegetable net sleeve machine. The rectangular net box can be installed by fitting one side of the frame, and the other side of the frame can be left empty for installing other components, maximizing the space utilization rate. A rectangular net box with a suitable length and height can be selected according to the fruit and vegetable net sleeve machine to improve its adaptability. Second, since the circumferences of the driving roller and the guiding roller are fixed, the alarm mechanism accurately obtains the usage amount of the net sleeve by monitoring the number of rotations of the driving roller or the guiding roller, thereby accurately controlling the output amount of the net sleeve. The alarm mechanism can also send a reminder message when the net sleeve is used up or about to be used up, avoiding the production line from stopping due to material shortage and ensuring the continuity of production.

[0006] Further, the length of the rectangular cage is greater than the width, and the feeding port and the discharging port are arranged along the length direction of the rectangular cage.

[0007] Adopting the foregoing technical solution, since the length is greater than the width, the rectangular cage can provide a larger internal space, so that more net sleeves can be stored, reducing the frequency of replenishing the net sleeves, improving the production efficiency, and also being suitable for the fruit and vegetable netting machine with limited width space. Secondly, arranging the feeding port and the discharging port along the length direction can ensure the smooth flow of the net sleeves inside the cage.

[0008] Further, the feeding port is located on the right side surface of the rectangular cage. A tail plate rotatably connected to the rectangular cage is provided on the right side surface of the rectangular cage. The tail plate has a first position for covering the feeding port and a second position for opening the feeding port. When the tail plate is in the second position, the tail plate is inclined relative to the horizontal plane so that the folded net sleeves slide into the rectangular cage under the action of gravity.

[0009] Adopting the foregoing technical solution, the inclined design when the tail plate is opened utilizes the gravity effect, so that the folded net sleeves can easily slide into the cage, which helps to reduce the phenomenon of jamming during the loading process of the net sleeves and simplifies the loading process.

[0010] Further, a limiting plate fixedly connected to the rectangular cage is provided at the bottom of the feeding port, and the limiting plate extends upward to limit the net sleeves from moving out of the feeding port.

[0011] Adopting the foregoing technical solution, the limiting plate can effectively prevent the net sleeves from accidentally falling off from the feeding port and ensure that the net sleeves will not slide out during the loading process.

[0012] Further, the bottom end of the tail plate is rotatably connected to the limiting plate through a hinge. A through hole is provided on the side wall of the feeding port, and a threaded hole is provided on the tail plate. The tail plate is fixed in the first position by a bolt passing through the through hole and then entering the threaded hole.

[0013] Adopting the foregoing technical solution, the cooperation of the bolt and the threaded hole can ensure that the tail plate is firmly fixed in the first position, that is, the position of covering the feeding port, to prevent accidental opening during use. The design of the hinge enables the tail plate to rotate freely as needed, facilitating switching between different positions and improving the flexibility of use. The tail plate can be easily fixed in the first position or opened to the second position by simply rotating the bolt, and the operation is simple and fast.

[0014] Further, a partition is provided inside the rectangular cage. The partition divides the rectangular cage into a storage space communicating with the feeding port and an output space communicating with the discharging port. A communication channel communicating the storage space and the output space is provided on the partition. The driving roller is located in the communication channel to draw the net sleeves in the storage space into the output space.

[0015] Through the above technical solution, the partition divides the mesh box into two independent spaces, which are used for storing and outputting mesh sleeves respectively, which helps to maintain the orderly flow of the mesh sleeves and reduce the mutual interference of the mesh sleeves during the transportation process. The active roller pulls the mesh sleeves into the output space, which can optimize the material flow and ensure that the mesh sleeves smoothly enter the next process.

[0016] Furthermore, the height of the active roller in the horizontal plane is higher than that of the guide roller, and the mesh sleeve is pulled by the active roller and enters the guide channel under the action of gravity.

[0017] Through the above technical solution, the design of the active roller being higher than the guide roller utilizes the effect of gravity rather than relying entirely on mechanical force, which can reduce the friction between the mesh sleeve and the active roller, making it easier for the mesh sleeve to slide into the guide channel under the traction of the active roller, thereby reducing the additional power requirement.

[0018] Furthermore, the rectangular mesh box is also provided with an operating opening for external tools to penetrate into the rectangular mesh box.

[0019] Through the above technical solution, by opening an operation port, the interior of the rectangular mesh box is visualized, and the staff can intuitively obtain the situation of the mesh inside the rectangular mesh box. In addition, the staff can directly perform operations such as threading the mesh and maintaining the device through the operation port.

[0020] Furthermore, a reinforcing rib for connecting two sides of the operating port is provided in the operating port.

[0021] Through the above technical solution, the reinforcing ribs can increase the structural strength around the operating port to prevent the operating port from being deformed when used for a long time or subjected to external forces.

[0022] Furthermore, the alarm mechanism includes a controller, an audible and visual alarm and an encoder, the encoder is connected to the active roller or the guide roller via a coupling, and the audible and visual alarm is connected to the encoder signal via the controller.

[0023] Through the above technical solution, the encoder can accurately measure the number of rotations of the active roller or guide roller, thereby accurately calculating the length of the mesh sleeve passing through, thereby accurately controlling the output of the mesh sleeve, and the controller can send a reminder message through the sound and light alarm when the mesh sleeve is exhausted or is about to be exhausted.

[0040] The technical solutions of the present utility model will be described in detail below with specific embodiments. These several specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0041] Such as Figures 1 to 5As shown in the figure, the utility model provides a counting rectangular net box device for a fruit and vegetable net covering machine, which is applicable to the fruit and vegetable net covering machine. The net sleeve 500 adopts a standard fruit and vegetable net sleeve 500 commonly used in the market. The net sleeve 500 of the counting rectangular net box device is added to the net covering device of the fruit and vegetable net covering machine. The counting rectangular net box device includes a rectangular net box for storing the net sleeve 500. The rectangular net box can be installed on one side of the machine frame, and the other side of the machine frame can be left empty for installing other components, making up for the blank spaces in the four corners of the circular disk layout, maximizing the space utilization rate. It is also possible to select a rectangular net box with appropriate length and height according to the width of the fruit and vegetable net covering machine or the net sleeve 500 to improve its adaptability. The rectangular net box is provided with a feeding port 141, a discharging port 111, a driving roller 200 and a guiding roller 210. The feeding port 141 allows the net sleeve 500 of a set length and folded state to enter the rectangular net box. The guiding rollers 210 are arranged in pairs on both sides of the discharging port 111 to form a guiding channel 220. The driving roller 200 is located upstream of the guiding roller 210. The folded net sleeve 500 passes through the driving roller 200 and the guiding channel 220 and is output from the discharging port 111. Since the circumferences of the driving roller 200 and the guiding roller 210 are fixed, the driving roller 200 is provided with an alarm mechanism for obtaining the number of rotations of the driving roller 200 and capable of sending a reminder message. The alarm mechanism accurately obtains the usage amount of the net sleeve 500 by monitoring the number of rotations of the driving roller 200, thereby accurately controlling the output amount of the net sleeve 500. The alarm mechanism can also send a reminder message when the net sleeve 500 is used up or about to be used up, avoiding the production line from stopping due to material shortage and ensuring the continuity of production.

[0042] Preferably, the length of the rectangular net box is greater than the width. The rectangular net box can provide a larger internal space, so that more net sleeves 500 can be stored, reducing the frequency of replenishing the net sleeves 500, improving production efficiency, and being also suitable for fruit and vegetable net covering machines with limited width space. The feeding port 141 and the discharging port 111 are arranged along the length direction of the rectangular net box, which can ensure the smooth flow of the net sleeve 500 inside the net box.

[0043] In order to make the input and output routes of the net sleeve 500 more reasonable, a partition plate 230 is arranged inside the rectangular net box. The partition plate 230 divides the rectangular net box into a storage space 150 communicated with the feeding port 141 and an output space 160 communicated with the discharging port 111. The partition plate 230 has a communication channel 170 for communicating the storage space 150 and the output space 160, which helps to keep the orderly flow of the net sleeve 500 and reduces the mutual interference of the net sleeves 500 during the conveying process. The driving roller 200 is located inside the communication channel 170 to pull the net sleeve 500 in the storage space 150 into the output space 160, which can optimize the material flow and ensure that the net sleeve 500 smoothly enters the next process.

[0044] Preferably, the height of the driving roller 200 in the horizontal plane is higher than that of the guiding roller 210. The mesh sleeve 500 is pulled by the driving roller 200 and enters the guiding channel 220 under the action of gravity, rather than relying entirely on mechanical force. This can reduce the friction between the mesh sleeve 500 and the driving roller 200, making it easier for the mesh sleeve 500 to slide into the guiding channel 220 under the traction of the driving roller 200 and reducing the additional power requirement.

[0045] In addition, the six faces of the rectangular net cage include a top surface 100, a bottom surface, a front surface 120, a rear surface, a left side surface 130, and a right side surface 140. The feed inlet 141 is located on the right side surface 140 of the rectangular net cage, and the discharge outlet 111 is located at one end of the bottom surface away from the feed inlet 141. A tail plate 142 rotatably connected to the rectangular net cage is provided on the right side surface 140 of the rectangular net cage. The tail plate 142 has a first position for covering the feed inlet 141 and a second position for opening the feed inlet 141. When the tail plate 142 is in the second position, the tail plate 142 is inclined relative to the horizontal plane so that the folded mesh sleeve 500 slides into the rectangular net cage under the action of gravity, which helps to reduce the phenomenon of jamming of the mesh sleeve 500 during the loading process and simplifies the loading process.

[0046] It should be noted that the communication channel 170 can be provided between the partition plate 230 and the top surface 100 of the rectangular net cage, or can be directly opened on the partition plate 230.

[0047] To realize the switching of the tail plate 142 between the first position and the second position, the bottom end of the tail plate 142 is rotatably connected to the limiting plate 146 through a hinge 143. The design of the hinge 143 enables the tail plate 142 to rotate freely as needed, facilitating switching between different positions and improving the flexibility of use. The limiting plate 146 also facilitates the installation of the hinge 143, effectively avoiding the difficulty of installing the hinge 143 when the bottom size of the rectangular net cage is small.

[0048] To keep the tail plate 142 in the first position, a through hole 144 is provided on the side wall of the feed inlet 141, and a threaded hole 145 is provided on the tail plate 142. The tail plate 142 is fixed in the first position by a bolt passing through the through hole 144 and then entering the threaded hole 145. The cooperation of the bolt and the threaded hole 145 can ensure that the tail plate 142 is firmly fixed in the first position, that is, the position covering the feed inlet 141, preventing accidental opening during use. By simply rotating the bolt out or in, the tail plate 142 can be easily fixed in the first position or opened to the second position, with simple and quick operation.

[0049] It should be noted that the positions of the through hole 144 and the threaded hole 145 can also be interchanged. A threaded hole 145 is provided on the side wall of the feed inlet 141, and a through hole 144 is provided on the tail plate 142.

[0050] To prevent the mesh sleeve 500 from moving out of the rectangular net box from the feed inlet 141 when the tail plate 142 is in the second position, a limiting plate 146 fixedly connected to the rectangular net box is provided at the bottom of the feed inlet 141. The limiting plate 146 extends upward to limit the mesh sleeve 500 from moving out of the feed inlet 141. Specifically, the limiting plate 146 extends upward from the bottom surface of the rectangular net box, and the limiting plate 146 can effectively prevent the mesh sleeve 500 from accidentally falling off from the feed inlet 141, ensuring that the mesh sleeve 500 will not slide out during the loading process.

[0051] To facilitate the staff to timely obtain the situation of the mesh sleeve 500 inside the rectangular net box, the rectangular net box is also provided with an operation opening 101 for an external tool to penetrate into the rectangular net box. Preferably, the operation opening 101 is located on the top surface 100 of the rectangular net box. The operation opening 101 extends from the right side surface 140 to the left side surface 130, enabling the observation of the entire interior of the rectangular net box, visualizing the interior of the rectangular net box, so that the staff can intuitively obtain the situation of the mesh sleeve 500 inside the rectangular net box. Moreover, the staff can directly perform operations such as threading the mesh sleeve 500 and maintaining the device through the operation opening 101.

[0052] Since the structural strength of the top surface 100 of the rectangular net box is reduced after the operation opening 101 is provided, a reinforcing rib 240 for connecting both sides of the operation opening 101 is also provided inside the operation opening 101. The reinforcing rib 240 can increase the structural strength around the operation opening 101 and prevent the operation opening 101 from deforming when used for a long time or under external force.

[0053] It should be noted that in order to further enhance the structural strength of the rectangular net box, reinforcing ribs 240 are also provided on the bottom surface of the rectangular net box.

[0054] In this embodiment, the alarm mechanism includes a controller, a sound and light alarm, an encoder 400, and a mounting bracket 420 for mounting the encoder 400. The sound and light alarm is signal-connected to the encoder 400 through the controller. The mounting bracket 420 is detachably connected to the rectangular net box, enabling the encoder 400 to be easily moved or replaced as needed, improving the flexibility of the device. The encoder 400 is connected to the driving roller 200 through a coupling 410. The encoder 400 can accurately measure the number of rotation turns of the driving roller 200, thereby accurately calculating the length of the mesh sleeve 500 passing through, and thus precisely controlling the output quantity of the mesh sleeve 500. The controller can send a reminder message through the sound and light alarm when the mesh sleeve 500 is used up or about to be used up.

[0055] Also, it should be noted that in this embodiment, the encoder 400 is fixed to the mounting bracket 420 by bolts, and the mounting bracket 420 is fixed to the front 120 and the rear of the rectangular cage by socket head bolts 310. A bearing bracket 250 is also provided on the rectangular cage. The driving roller 200 is supported on the bearing bracket 250 by bearings 260, and the bearing bracket 250 is fixed to the front 120 and the rear of the rectangular cage by countersunk head bolts 320. Waist-shaped holes are provided on the front 120 and the rear of the rectangular cage, and the waist-shaped holes extend along the length direction of the rectangular cage. The guide rollers 210 are fixed to the waist-shaped holes by bolts and nuts. The reinforcing ribs 240 on the bottom surface of the rectangular cage are fixedly connected by bolts. The partition plate 230 is fixed to the bottom surface, the front 120 and the rear of the rectangular cage by bolts and is fixed to the reinforcing ribs 240 on the bottom surface by bolts. The first brackets 430 and the second brackets 440 are provided on both the front 120 and the rear of the rectangular cage. The first brackets 430 and the second brackets 440 are arranged left and right along the rectangular cage. The first brackets 430 and the second brackets 440 are fixed to the reinforcing ribs 240 at the bottom by bolts passing through the front 120 and the rear of the rectangular cage. The reinforcing ribs 240 on the top surface 100 of the rectangular cage are fixed to the front 120 and the rear of the rectangular cage by bolts.

[0056] Usage steps, Step1: When the encoder 400 in the rectangular cage detects that the mesh sleeve 500 is used up, it issues a prompt that the mesh sleeve 500 is used up, and then the neatly folded mesh sleeve 500 is taken to near the rectangular cage.

[0057] Step2: As Figure 2 shown, unscrew the wing bolt 300 and open the tail plate 142 to the second position so that it forms a certain angle with the partition plate 230 to facilitate the neatly folded mesh sleeve 500 to slide in.

[0058] Step3: After the neatly folded mesh sleeve 500 is completely slid in, turn the tail plate 142 to the first position. As Figure 3 shown, fix the tail plate 142 with the wing bolt 300.

[0059] Step4: After the above steps are completed, loosen the bolts and nuts, and the guide rollers 210 move in the waist-shaped holes. At this time, the distance of the guide channel 220 is the largest, that is, the distance between the two guide rollers 210 is the largest, which facilitates the insertion of the mesh sleeve 500.

[0060] Step5: Then, thread the neatly folded mesh sleeve 500 in the arrow order of Figure 4 . After the threading is completed, move the two guide rollers 210 to the position where the mesh sleeve 500 is clamped, lock the nuts, and fix it.

[0061] Step 6: Subsequently, add the net sleeve 500 to the net-sleeving device of the fruit and vegetable net-sleeving machine. Wait for the net-sleeving device to operate. The net sleeve 500 exits the net orderly in the rectangular net box. As the net sleeve 500 moves, it drives the driving roller 200 to rotate, and the encoder 400 rotates together with it. When the net sleeve 500 is used up and the encoder 400 counts to a certain length, a reminder to add the net sleeve 500 is given.

[0062] Step 7: Repeat the above steps 1 - 6 for cyclic operation.

[0063] It should be noted that the reminder working principles of Step 1 and Step 6 are as follows: Assume that an encoder 400 outputs 100 pulses per revolution, and the driving roller 200 sends out a section of the net sleeve 500 per revolution. If an alarm needs to be issued before the net sleeve 500 is used up, it can be set as follows:

[0064] Calculate the threshold: Assume that the total length of the net sleeve 500 corresponds to 10,000 pulses output by the encoder 400. Set the alarm threshold to 9,000 pulses, that is, when the cumulative output of the encoder 400 reaches 9,000 pulses, the alarm is triggered.

[0065] Programming logic: Write a program in the controller to monitor the output pulse count of the encoder 400. When the cumulative pulse count reaches 9,000, the controller triggers an alarm output.

[0066] Alarm output: The controller triggers an audible and visual alarm through the I / O interface.

[0067] It can be understood that in other embodiments, the alarm mechanism can also be provided on the guide roller. The alarm mechanism accurately obtains the usage amount of the net sleeve by monitoring the number of rotations of the guide roller, so as to accurately control the output amount of the net sleeve. Correspondingly, the encoder is connected to the driving roller through a coupling.

[0068] It can be understood that in other embodiments, the width of the rectangular net box can be greater than the length to adapt to different fruit and vegetable net-sleeving machines.

[0069] It can be understood that in other embodiments, the tail plate can also be rotatably connected to the limiting plate through a rotating shaft. Of course, it can also be rotatably connected to the front and back of the rectangular net box through a rotating shaft. And it is limited to this.

[0070] It can be understood that in other embodiments, the tail plate can be fixed at the first position through a snap structure. Of course, it can also be fixed at the first position through structures such as hanging ropes and door locks.

[0071] It can be understood that in other embodiments, the alarm mechanism can also adopt a photoelectric sensor, which emits light to the driving roller or the guiding roller and waits for a reflected signal. If there is a mesh sleeve, the reflected signal will change; if there is no mesh sleeve, the reflected signal will remain the same. Of course, it is also possible to install a weight sensor under the driving roller or the guiding roller. When the mesh sleeve is present, the weight sensor will detect a certain weight; when there is no mesh sleeve, the weight sensor will detect a smaller or zero weight. It is not limited to this.

[0072] It can be understood that in other embodiments, the mesh sleeve can also be automatically threaded through mechanical means.

[0073] In addition to the above preferred embodiments, the present utility model has other implementation manners. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection claimed by the present utility model.
