Description

Technical Field

[0001] The invention relates to the technical field of automatic fruit protective film removal equipment, in particular to a fruit film stripping machine. Background Art

[0002] Fruit bagging technology has been widely used in orchards due to its remarkable effects. The role of fruit bagging is in the later stage of growth. Under the premise of not affecting or damaging the normal growth and maturity of the fruit, the fruit film bag not only isolates pesticides and environmental pollution to make the fruit pollution-free, but also makes the surface of mature fruit smooth by isolating pests and diseases and dust.

[0003] The fruit picking work includes picking the fruit and removing the fruit film bags. For example, the patent with the announcement number CN205196510U discloses a semi-automatic fruit film bagging device, which is to bag the growing fruits. When the fruits are ripe, the fruit film bags need to be removed for picking and selling.

[0004] At present, there are two time periods for removing film bags of fruits. One is that workers remove the film bags of picked fruits while picking them, and the other is that fruits with film bags are picked and then processed collectively to remove the film bags. In the above two time periods, the picking and removal of fruit film bags need to be removed manually by workers. Manual removal of fruit film bags by workers will extend the working time of fruit picking, and thus the efficiency of fruit picking needs to be improved. Summary of the invention

[0005] The object of the present invention is to provide a fruit peeling machine to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a fruit defilming machine, comprising a frame and a feed port and a discharge port arranged on the frame, and also comprising at least one conveying and defilming unit and a driving assembly, the conveying and defilming unit comprising a conveying roller and a defilming roller both rotatably connected to the frame, the conveying roller and the defilming roller are parallel to each other, a spiral conveying groove is provided on the circumferential side surface of the conveying roller, and a plurality of defilming protrusions are distributed on the circumferential side surface of the defilming roller; the driving assembly is used to drive the conveying roller and the defilming roller to rotate in opposite directions.

[0007] Furthermore, the groove spacings of each section on the spiral conveying groove are equal.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] See also Figure 1-8 A fruit peeling machine provided by an embodiment of the present invention comprises a frame 1 and a feed port 11 and a discharge port 12 arranged on the frame 1, and also comprises a conveying and peeling unit and a driving assembly. The conveying and peeling unit comprises a conveying roller 2 and a peeling roller 3 both rotatably connected to the frame 1. The conveying roller 2 and the peeling roller 3 are parallel to each other. A spiral conveying groove 21 is provided on the peripheral side of the conveying roller 2. Specifically, the spiral conveying groove 21 has two forms. The first form is as follows: Figure 4 When the groove spacing of each section on the spiral conveying groove 21 is equal, the conveying roller 2 can convey standard fruit shapes or smaller fruits; the second type is as follows Figure 5, the groove spacing of each section on the rotary conveying trough is not equal or not completely equal (the groove spacing of each section on the rotary conveying trough in the front half of the conveying roller 2 is equal, and the groove spacing of each section on the rotary conveying trough in the rear half of the conveying roller 2 increases successively). In this state, larger fruits can be conveyed. A plurality of demolding protrusions 31 are distributed on the peripheral side of the demolding roller 3, as shown in the specific Figure 3 The demolding convex head 31 includes a cylindrical block 311 and a spherical block 312, one end of the cylindrical block 311 is fixedly connected to the demolding roller 3, and the other end of the cylindrical block 311 is fixedly connected to the spherical block 312; the driving component is used to drive the conveying roller 2 and the demolding roller 3 to rotate in opposite directions, the driving component includes a servo motor 4, a transmission component 5 and two first gears 6, one of which is coaxially fixedly connected to the conveying roller 2, and the other first gear 6 is coaxially fixedly connected to the demolding roller 3, the two first gears 6 are meshed with each other, the servo motor 4 drives one of the first gears 6 to rotate through the transmission component 5, the transmission component 5 includes a driving wheel 51, a driven wheel 52 and a conveyor belt 53, the driving wheel 51 is coaxially fixedly connected to the output shaft of the servo motor 4, the driven wheel 52 is coaxially fixedly connected to a first gear 6, and the conveyor belt 53 is wrapped around the driving wheel 51 and the driven wheel 52.

[0027] Working principle: workers will pile the picked fruits with film bags into the collection frame, and the workers will transport the collection frame with fruits to the side of the film stripping machine. At this time, the workers need to turn on the servo motor 4. The start of the servo motor 4 will drive the driving wheel 51 to rotate, and the rotation of the driving wheel 51 will drive the driven wheel 52 to rotate through the conveyor belt 53, and then the driven wheel 52 can drive a first gear 6 to rotate. Since the two first gears 6 are meshed with each other, one gear rotates to drive the other first gear 6 to rotate. At this time, the conveying roller 2 and the film stripping roller 3 will rotate in opposite directions at the same time. The workers can slowly put the fruits with film bags in the collection frame into the feed port 11 of the film stripping machine through manual handling or mechanical arms. The fruits fall from the feed port 11 between the conveying roller 2 and the film stripping roller 3 (some fruits may fall between the film stripping roller 3 and the frame 1, and at this time they can be on the frame 1 An inclined plate is provided between the discharge port 12 and the conveying and demolding unit so that the fruit can fall along the inclined plate between the demolding roller 3 and the conveying roller 2). When the conveying roller 2 drives the fruits to be transported to the discharge port 12, the demolding protrusions 31 on the demolding roller 3 will pull the protective film bags of the fruits during the circular motion, so that the protective film bags of the fruits are pulled to the position below the conveying and demolding unit (the spherical blocks 312 of the demolding protrusions 31 are used to reduce the contact area between the demolding protrusions 31 and the fruits to protect the fruits. The demolding protrusions 31 are made of rubber material to prevent the demolding protrusions 31 from being too hard to scratch the fruits, thereby protecting the fruits. The columnar blocks 311 of the demolding protrusions 31 are fixedly connected to the demolding roller 3 so as to provide more demolding protrusions 31 on the demolding roller 3). The fruits separated from the protective film bags enter the fruit collection frame from the discharge port 12 of the demolding machine.

[0028] In addition, Figure 1 Each leg of the frame 1 is provided with a universal wheel to facilitate the movement of the film stripping machine.

[0029] Compared with the prior art, the present invention provides a fruit defilming machine. After the workers have picked a certain number of fruits with film bags, the workers can slowly put the batch of fruits into the feed port 11 of the defilming machine. The conveying and defilming unit can make the batch of fruits entering the machine move to the discharge port 12 of the defilming machine in sequence. During the movement of each fruit, the conveying and defilming unit also defilms each fruit. Each fruit conveyed to the discharge port 12 has been separated from the protective film bag. During the fruit defilming process, only one worker needs to put in the fruit operating device, and other workers can continue to pick fruits. At this time, the fruit picking efficiency is effectively improved, and the best time period for collecting fruits due to low picking efficiency is avoided.

[0030] In another embodiment provided by the present invention, there are two conveying and demolding units, which are arranged in parallel. The driving component includes a servo motor 4 and a transmission component 5. The two conveying rollers 2 and the two demolding rollers 3 are coaxially fixedly connected with a second gear 7, and the two adjacent second gears 7 are meshed with each other. The servo motor 4 drives one of the second gears 7 to rotate through the transmission component 5. The transmission component 5 includes a driving wheel 51, a driven wheel 52 and a conveyor belt 53. The driving wheel 51 is coaxially fixedly connected to the output shaft of the servo motor 4, the driven wheel 52 is coaxially fixedly connected to a second gear 7, and the conveyor belt 53 is wrapped around the driving wheel 51 and the driven wheel 52.

[0031] Working principle: The worker needs to turn on the servo motor 4. The start of the servo motor 4 drives the driving wheel 51 to rotate. The rotation of the driving wheel 51 will drive the driven wheel 52 to rotate through the conveyor belt 53, and then the driven wheel 52 can drive a second gear 7 to rotate. Since the two adjacent second gears 7 are meshed, the rotation of one second gear 7 will drive the rotation of the other three second gears 7 (such as Figure 8For example, if a second gear 7 arranged on the side rotates clockwise, another second gear 7 adjacent to and meshing with the second gear 7 will rotate counterclockwise. If a second gear 7 arranged in the middle rotates clockwise, the other two second gears 7 on both sides meshing with the second gear 7 will rotate counterclockwise. Since the two conveying rollers 2 and the two film stripping rollers 3 are arranged alternately, the transmission directions of the two conveying rollers 2 are the same. The worker puts the fruits with film bags from the feed port 11 of the film stripping machine onto the two conveying and film stripping units. The conveying rollers 2 drive the fruits to move. During the process of being transported to the discharge port 12, the demolding protrusions 31 on the demolding roller 3 will pull the protective film bag of the fruit during the circular motion, so that the protective film bag of the fruit is pulled to the position below the conveying and demolding unit, and the fruits separated from the protective film bag enter the fruit collection frame from the discharge port 12 of the demolding machine. In addition, two inclined plates can be arranged on the frame 1 between the two conveying and demolding units, and the fruit can fall from the feed port 11 along the two inclined plates to between the conveying roller 2 and the demolding roller 3, so as to prevent the fruit from falling between the two conveying and demolding units and making it impossible to feed the fruit.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
