Description

Technical Field

[0001] This utility model belongs to the field of fruit demulsification technology, specifically relating to a fruit demulsification device. Background Technology

[0002] Currently, fresh fruit is generally transported via cold chain logistics to ensure it stays fresh for longer during transit. However, not all fruits are suitable for freezing. Freezing can cause fruits to lose some of their flavor, and the thawed experience is significantly worse than that of fresh fruit. Therefore, cold chain logistics uses a certain degree of cooling to prevent excessive freezing and quality degradation. However, even with freezing, the fruit still loses moisture more quickly. To extend the shelf life of fruit, wrapping it in plastic wrap can effectively reduce moisture loss, ensuring that the fruit retains its fresh flavor upon arrival at its destination. Therefore, fruit wrapped in plastic wrap is suitable for large-volume and long-term transportation.

[0003] However, after transportation, the plastic wrap needs to be removed before the fruit can be eaten. This doesn't have a big impact on retail and bulk sales, as it can be removed manually. But for factory production and processing, manually removing the plastic wrap from each fruit delivered in batches is too inefficient and will affect the fruit processing and production process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a fruit de-wrapping device. The fruit, which has been wrapped in plastic wrap, is placed in the feeding hopper and driven into the de-wrapping assembly by the conveyor wheel. The fruit is then driven forward by the continuously rotating conveyor roller. As the de-wrapping roller rotates, it carries in and removes the plastic wrap. Finally, the de-wrapped fruit falls out from the discharge channel.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A fruit demolding device includes a frame, a feeding assembly, and a demolding assembly, both of which are mounted on the frame. The demolding assembly includes a support frame, a drive motor, and a demolding component. The support frame is mounted on the frame, and the drive motor is mounted on the support frame. The demolding component includes a conveying roller and a demolding roller rotatably connected to the support frame. The conveying roller and the demolding roller are arranged side-by-side and abut against each other. The output end of the drive motor is connected to the conveying roller and drives it to rotate. During rotation, the conveying roller drives the demolding roller to rotate. The feeding assembly faces the upper end between the conveying roller and the demolding roller.

[0006] The outer wall of the conveying roller is provided with an outwardly extending spiral ridge, the side wall of the ridge and the outer wall of the conveying roller forming a spiral embedded groove; the outer wall of the stripping roller is provided with a plurality of square particles, the square particles do not contact each other, the square particles abut against the ridge; the plurality of square particles are arranged in an array on the outer wall of the stripping roller, the intervals between the plurality of square particles along the rotation direction of the stripping roller forming a through annular groove, the annular groove includes a plurality of groups and is arranged in an array along the axial direction of the stripping roller; the stripping component also includes a waste cleaning knife, the waste cleaning knife is mounted on a support frame, the waste cleaning knife is provided with a plurality of square teeth arranged in an array, the square teeth cooperate with the annular groove.

[0007] The demolding assembly comprises two sets, symmetrically arranged about the central axis of the support frame. Along the central axis of the support frame, a conveying roller, a demolding roller, and a waste removal knife are arranged sequentially. The protrusions of the two sets of conveying rollers do not contact each other, and their ends are meshed through two sets of transmission gears. The output of the drive motor is connected to one set of conveying rollers and drives its rotation. The demolding assembly also includes a tensioning component, comprising two sets of tensioning rods, a screw, a spring, and several nuts. The two sets of tensioning rods are rotatably connected to the support frame at their middle parts. The upper ends of the two sets of tensioning rods are rotatably connected to the shafts of the two sets of demolding rollers, respectively. The left and right ends of the screw pass through the lower ends of the two sets of tensioning rods, respectively. The inner side of one end of the screw abuts against one set of tensioning rods through a screw-in nut, and the inner side of the other end of the screw abuts against the other set of tensioning rods through a screw-in nut and a spring sleeved on the screw. The demolding assembly also includes a feed channel and a discharge channel, which are sequentially distributed on the support frame.

[0008] The fruit de-filming device with this structure places the fruit to be de-filmed in the feeding assembly and conveys it to the de-filming assembly. To achieve the de-filming effect, a conveying roller and a de-filming roller are set up. The conveying roller and the de-filming roller are arranged side by side and abut against each other. During the rotation of the conveying roller by the drive motor, the de-filming roller rotates synchronously. The rotation direction of the conveying roller is downward at the point where the conveying roller and the de-filming roller abut against each other. Therefore, when the fruit enters the upper part between the conveying roller and the de-filming roller from the feeding assembly, the plastic wrap will be subjected to downward transmission force. Once the plastic wrap is bitten between the conveying roller and the de-filming roller, it will be de-filmed downward with the rotation direction until all the plastic wrap is removed.

[0009] However, if too many fruits are fed into the machine, it will affect the efficiency of the demolding process, and some fruits may even fail to be demolded. Therefore, a spiral protrusion is provided on the outer wall of the conveyor roller. The side wall of the protrusion and the outer wall of the conveyor roller form a spiral embedding groove. The embedding groove is wide enough that only one fruit can be embedded in the embedding groove at a time during rotation. On the upward-facing surface, the fruits are distributed in an array and are transmitted along the direction of rotation. Therefore, the fruits maintain a distance from each other and will not affect each other's demolding.

[0010] However, relying solely on the contact points between the conveying roller and the unwrapping roller to pull down the plastic wrap is insufficient for tightly wrapped fruits. To improve unwrapping efficiency, several square particles are set on the outer wall of the unwrapping roller. These square particles do not contact each other, so the gaps between them make it easy for the plastic wrap to be caught during rotation, thereby pulling it down and improving unwrapping efficiency.

[0011] However, the square granules can easily become clogged by the cling film, preventing the cling film from adhering to the subsequent fruits being unwrapped. This causes the entire unwrapping roller to lose its unwrapping function after prolonged operation. To avoid this, several square granules are arranged in a longitudinal and transverse array. A continuous annular groove is formed between the square granules along the rotation direction of the unwrapping roller. The annular groove is arrayed along the axial direction of the unwrapping roller. Simultaneously, a waste removal knife is added to the support frame. The square teeth on the waste removal knife engage within the annular groove. Since the stripping roller is in a rolling state while the waste removal knife is stationary, the plastic wrap hanging on the annular groove will inevitably pass through the square teeth during the rotation of the stripping roller. The square teeth can effectively remove the plastic wrap, thus avoiding the plastic wrap from affecting the subsequent stripping. Once the plastic wrap brought in by the high-speed rotating stripping roller hits the square teeth, it will be torn and shredded and fall off. Moreover, the fruit to be stripped passes through one by one, and the plastic wrap covering it is only a thin layer. Therefore, the amount of plastic wrap passing through each time is not enough to cause the roller to jam.

[0012] To improve the efficiency of peeling, the peeling components are set into two sets, which are arranged side by side and symmetrical about the support frame as the central axis. Along the central axis of the support frame, the conveying roller, the peeling roller, and the waste removal knife are arranged in sequence. The two sets of conveying rollers do not contact each other and their rotation directions must be opposite to ensure that the two sets of peeling components can remove the plastic wrap from the fruit on them. In order to achieve synchronous rotation of the two sets of conveying rollers, two sets of transmission gears are set at the ends of the two sets of conveying rollers and mesh with each other. The drive motor drives one set of conveying rollers to rotate, thus achieving synchronous rotation of the two sets of conveying rollers. In addition, to maintain the contact between the demolding roller and the conveyor roller, and thus ensure the transmission of the conveyor roller to the demolding roller, a tensioning component is added. This is achieved through two sets of tensioning rods rotatably connected to the support frame at their midpoints. The upper ends of the tensioning rods are rotatably connected to the axis of the demolding roller, while the lower ends pass through screws. Therefore, while the lower ends of the two sets of tensioning rods are pushed outwards relative to each other, their upper ends move inwards relative to each other, thus strengthening the contact with the conveyor roller. A screw nut is tightened at one end of the screw to contact the lower end of one set of tensioning rods, and a screw nut and a spring fitted on the screw at the other end of the screw to contact the lower end of the other set of tensioning rods. Therefore, as the nut contacting the spring is gradually tightened, the deformation of the spring increases the spreading force on the tensioning rods, thereby strengthening the friction between the demolding roller and the conveyor roller. Meanwhile, a feeding channel is set at the inlet of the demolding component to facilitate the entry of the fruit to be demolded, and a discharge channel is set at its outlet to facilitate the exit of the demolded fruit, thus realizing the fruit demolding through the equipment.

[0013] Furthermore, the feeding assembly includes a feeding bin, a feeding channel, and a conveying component. The feeding bin and the feeding channel are connected in sequence and face the feeding channel. The conveying component is located at the bottom of the feeding bin and the feeding channel. The conveying component includes a conveyor chain, conveyor wheels, and a conveyor motor. The conveyor chain is rotatably connected to the feeding channel. The conveyor motor is located on the feeding channel and drives the conveyor chain to rotate. The conveyor wheels include several groups arranged in an array on the conveyor chain. Several of the conveyor wheels are driven by the conveyor motor to move sequentially along the feeding bin towards the feeding channel. A dividing groove is provided in the middle of the conveyor wheel. The conveying component also includes a strip-shaped rejecting component, which is connected to the feeding channel and located in the dividing groove on several conveyor wheels. The demolding assembly also includes a dividing plate, which is vertically arranged on the feeding channel and corresponds to the rejecting component.

[0014] Compared with the prior art, the advantages of this utility model are as follows: the conveying rubber roller with convex strips abuts against several square particles on the demolding rubber roller. When driven by the drive motor, the fruit to be demolded is moved in the axial direction of the conveying rubber roller. At the same time, the plastic wrap on the fruit to be demolded is caught by the square particles and pulled down along the rotation direction of the demolding rubber roller, so that the plastic wrap is detached. The plastic wrap caught on the square particles is blocked by the square teeth on the waste removal knife during the rotation, thereby effectively removing the plastic wrap on the annular groove and avoiding the subsequent demolding due to the obstruction of the plastic wrap.

[0019] The specific embodiments of this utility model will now be described with reference to the accompanying drawings: like Figure 1-9 As shown, a fruit demolding device includes a frame 1, a feeding assembly 2, and a demolding assembly 3, both of which are mounted on the frame 1. The demolding assembly 3 includes a support frame 31, a drive motor 32, and a demolding component 33. The support frame 31 is mounted on the frame 1, and the drive motor 32 is mounted on the support frame 31. The demolding component 33 includes a conveying roller 331 and a demolding roller 332 rotatably connected to the support frame 31. The conveying roller 331 and the demolding roller 332 are arranged side by side and abut against each other. The output end of the drive motor 32 is connected to the conveying roller 331 and drives the conveying roller 331 to rotate. During the rotation of the conveying roller 331, the demolding roller 332 is driven to rotate. The feeding assembly 2 is positioned at the upper end between the conveying roller 331 and the demolding roller 332.

[0020] The outer wall of the conveying roller 331 is provided with outwardly extending spiral protrusions 333, and the sidewalls of the protrusions 333 and the outer wall of the conveying roller 331 form a spiral embedded groove 334; the outer wall of the stripping roller 332 is provided with a plurality of square particles 335, which do not contact each other, but abut against the protrusions 333; the plurality of square particles 335 are distributed in an array on the outer side of the stripping roller 332. On the side wall, several square particles 335 are spaced apart along the rotation direction of the stripping roller 332 to form a through annular groove 336. The annular groove 336 includes several groups and is arranged in an array along the axial direction of the stripping roller 332. The stripping component 33 also includes a waste removal knife 337, which is mounted on the support frame 31. The waste removal knife 337 is provided with several square teeth 338 arranged in an array, and the square teeth 338 cooperate with the annular groove 336.

[0021] The demolding components 33 include two sets, which are symmetrical about the central axis of the support frame 31. Along the central axis of the support frame 31, a conveying roller 331, a demolding roller 332, and a waste removal knife 337 are arranged sequentially outwards. The protrusions 333 of the two sets of conveying rollers 331 do not contact each other, and the ends of the two sets of conveying rollers 331 mesh with each other through two sets of transmission gears 339. The output end of the drive motor 32 is connected to one set of conveying rollers 331 and drives it to rotate. The demolding assembly 3 also includes a tensioning component 37, which includes two sets of tensioning rods 371, a screw 372, a spring 373, and several nuts 374. The tensioning rod 371 is rotatably connected to the support frame 31 at its middle part. The upper ends of the two sets of tensioning rods 371 are rotatably connected to the shafts of the two sets of demolding rollers 332, respectively. The left and right ends of the screw 372 pass through the lower ends of the two sets of tensioning rods 371, respectively. The inner side of one end of the screw 372 abuts against one set of tensioning rods 371 through a screw-fit nut 374. The inner side of the other end of the screw 372 abuts against another set of tensioning rods 371 through a screw-fit nut 374 and a spring 373 sleeved on the screw 372. The demolding assembly 3 also includes a feed channel 34 and a discharge channel 35. The feed channel 34, demolding assembly 33 and discharge channel 35 are distributed sequentially on the support frame 31.

[0022] Further, the feeding assembly 2 includes a feeding bin 21, a feeding channel 22, and a conveying component 23. The feeding bin 21 and the feeding channel 22 are connected in sequence and face the feeding channel 34. The conveying component 23 is located at the bottom of the feeding bin 21 and the feeding channel 22. The conveying component 23 includes a conveyor chain 231, conveyor wheels 232, and a conveyor motor 233. The conveyor chain 231 is rotatably connected to the feeding channel 22. The conveyor motor 233 is disposed on the feeding channel 22 and drives the conveyor chain 231 to rotate. The conveyor wheels 232 include several groups arranged in an array. The conveyor belt 231 is arranged on the conveyor chain 231. Several conveyor wheels 232 are driven by the conveyor motor 233 to move sequentially along the feeding bin 21 towards the feeding channel 22. The conveyor wheel 232 is provided with a partition groove 234 in the middle. The conveying component 23 also includes a strip-shaped rejecting member 235. The rejecting member 235 is connected to the feeding channel 22 and located in the partition groove 234 on the several conveyor wheels 232. The demolding component 3 also includes a partition plate 36. The partition plate 36 is vertically arranged on the feeding channel 34. The partition plate 36 corresponds to the rejecting member 235.

[0023] Description of the working principle of this utility model: In this fruit de-filming device, the fruit to be de-filmed is placed in the feeding assembly 2 and conveyed to the de-filming assembly 3. To achieve the de-filming effect, a conveying roller 331 and a de-filming roller 332 are set up side by side and abut against each other. During the rotation of the conveying roller 331 driven by the drive motor 32, the de-filming roller 332 is driven to rotate synchronously. The rotation direction of the conveying roller 331 is downward at the point where the conveying roller 331 and the de-filming roller 332 abut against each other. Therefore, when the fruit enters the upper part between the conveying roller 331 and the de-filming roller 332 from the feeding assembly 2, the plastic wrap will be subjected to downward transmission force. Once the plastic wrap is bitten between the conveying roller 331 and the de-filming roller 332, it will be de-filmed downward with the rotation direction until all the plastic wrap is removed.

[0024] However, if too many fruits are introduced, the demolding efficiency will be affected, and some fruits may even fail to be demolded. Therefore, a spiral protrusion 333 is provided on the outer wall of the conveyor roller 331. The side wall of the protrusion 333 and the outer wall of the conveyor roller 331 form a spiral embedding groove 334. The embedding groove 334 is relatively wide, so that only one fruit can be embedded in the embedding groove 334 at a time during rotation. On the upward surface, the fruits are distributed in an array and are transmitted along the direction of rotation. Therefore, the fruits maintain a distance from each other and will not affect each other's demolding.

[0025] However, relying solely on the contact points between the conveying roller 331 and the unwrapping roller 332 to pull down the plastic wrap is insufficient for tightly wrapped fruits. To improve unwrapping efficiency, several square particles 335 are arranged on the outer wall of the unwrapping roller 332. The square particles 335 do not contact each other, so the gaps between them make it easy to wedge the plastic wrap into them during rotation, thereby pulling it down and improving unwrapping efficiency.

[0026] However, the square granules 335 are also prone to getting clogged by the cling film, preventing the cling film from sticking to the subsequent fruits to be unwrapped. This causes the entire unwrapping roller 332 to lose its unwrapping function after prolonged operation. To avoid this, several square granules 335 are arranged in a longitudinal and transverse array. A continuous annular groove 336 is formed between the square granules 335 along the rotation direction of the unwrapping roller 332. The annular groove 336 is arranged in an array along the axial direction of the unwrapping roller 332. Simultaneously, a waste removal knife 337 is added to the support frame 31. The square teeth 338 on the waste removal knife 337 engage with the annular groove 336. Inside the groove 336, since the stripping roller 332 is in a rolling state while the waste removal knife 337 is stationary, the plastic wrap hanging on the annular groove 336 will inevitably pass through the square teeth 338 during the rotation of the stripping roller 332. The plastic wrap can be effectively removed by the square teeth 338, thus avoiding the plastic wrap from affecting the subsequent stripping. Once the plastic wrap brought in by the high-speed rotating stripping roller 332 hits the square teeth 338, it will be torn and shredded and fall off. Moreover, the fruit to be stripped passes through one by one, and the plastic wrap covering it is only a thin layer. Therefore, the amount of plastic wrap passing through each time is not enough to cause the roller to jam.

[0027] To improve the efficiency of peeling, the peeling components 33 are set into two groups, which are arranged side by side and symmetrical about the support frame 31 as the central axis. Along the central axis of the support frame 31, the conveying roller 331, the peeling roller 332, and the waste removal knife 337 are arranged outward in sequence. The two adjacent conveying rollers 331 do not contact each other and their rotation directions must be opposite to achieve the removal of the plastic wrap from the fruit to be peeled by the two sets of peeling components 33. In order to achieve synchronous rotation of the two sets of conveying rollers 331, two sets of transmission gears 339 are set at the ends of the two sets of conveying rollers 331 and mesh with each other. The drive motor 32 drives one of the sets of conveying rollers 331 to rotate, thus achieving synchronous rotation of the two sets of conveying rollers 331. Furthermore, in order to maintain the contact between the demolding roller 332 and the conveying roller 331, and thus maintain the transmission of the demolding roller 332 by the conveying roller 331, a tensioning member 37 is added. This is achieved through two sets of tensioning rods 371 rotatably connected to the support frame 31 at their midpoints. The upper ends of the tensioning rods 371 are rotatably connected to the axis of the demolding roller 332, while the lower ends of the tensioning rods 371 pass through screws 372. Therefore, while the lower ends of the two sets of tensioning rods 371 are relatively pushed outwards, the upper ends of the two sets of tensioning rods 371 are relatively pulled inwards. To strengthen the contact with the conveyor roller 331, a screw nut 374 is tightened to the inner side of one end of the screw 372, which abuts against the lower end of a set of tension rods 371. The screw nut 374 and a spring 373 fitted onto the screw 372 abut against the lower end of another set of tension rods 371. Therefore, as the nut 374 abuts against the spring 373 is gradually tightened, the deformation of the spring 373 increases the spreading force on the tension rods 371, thereby strengthening the friction between the demolding roller 332 and the conveyor roller 331. Simultaneously, a feed channel 34 is provided at the inlet of the demolding component 33 to facilitate the entry of the fruit to be demolded, and a discharge channel 35 is provided at its outlet to facilitate the exit of the demolded fruit, thus achieving fruit demolding through the equipment.

[0028] To further improve the demolding efficiency of fruits in the dual-channel system, the fruits fed into the feeding assembly 2 can be pre-divided into two groups. Firstly, a feeding bin 21 is set up to store the fruits to be demolded. The conveyor chain 231, driven by the conveyor motor 233, moves the arrayed conveyor wheels 232 along the feeding channel 22, continuously engaging the fruits between the two sets of conveyor wheels 232, bringing them into the feeding bin 21, and moving them along the feeding channel 22 towards the feeding channel 34 until the fruits are conveyed. To enable dual channels, a separating groove 234 is set in the middle of the conveyor wheels 232. Simultaneously, a strip-shaped rejecting element 235 is added and positioned on several conveyor wheels. Within the dividing groove 234 between the conveying wheels 232, the fruit to be de-wrapped is obstructed by the rejecting element 235 during upward conveying and is divided into two columns for upward displacement. If necessary, the rejecting element 235 can be abutted against the dividing groove 234. The conveying wheels 232 are rotatably connected to the conveyor chain 231. Therefore, while the conveying wheels 232 are displaced by the conveyor chain 231, they are abutted by the rejecting element 235, causing the conveying wheels 232 to be driven to rotate. Thus, the fruit to be de-wrapped between the conveying wheels 232 will also rotate continuously and maintain displacement. More preferably, two sets of conveyor chains 231 are provided, located at the left and right ends of the conveying wheels 232.

[0029] If there is no obstruction when the dual-channel fruits to be unwrapped fed from the conveyor wheel 232 enter the feeding channel 34, two fruits may enter the unwrapping component 33 on one side at the same time, while no fruit enters the unwrapping component 33 on the other side. Therefore, a partition plate 36 is added to the feeding channel 34. The vertically arranged partition plate 36 can ensure that the fruits to be unwrapped transported from the dual channels can enter the unwrapping components 33 on both sides in sequence, so as to achieve unwrapping of each other without interference.

[0030] The beneficial effects of this utility model are as follows: the conveying roller 331 with protrusions 333 abuts against several square particles 335 on the demolding roller 332. When driven by the drive motor 32, the fruit to be demolded is moved in the axial direction of the conveying roller. At the same time, the plastic wrap on the fruit is caught by the square particles 335 and pulled down along the rotation direction of the demolding roller 332, so that the plastic wrap is detached. The plastic wrap caught on the square particles 335 is blocked by the square teeth 338 on the waste removal knife 337 during the rotation, thereby effectively removing the plastic wrap on the annular groove 336, thus avoiding the subsequent demolding due to the obstruction of the plastic wrap.
