Description

Technical Field

[0001] This utility model relates to the field of raisin processing technology, specifically to a raisin bag anti-clogging device. Background Technology

[0002] On automated packaging production lines for dried fruits such as raisins, the bagging process often involves weighing the materials quantitatively and then filling them into pre-made packaging bags through a feeding port. However, due to the characteristics of raisins—numerous surface wrinkles, high sugar content, irregular granules, and easy moisture absorption—they are prone to sticking, bridging, accumulating, or even clogging at the discharge port or guide pipe during the feeding process. This leads to poor feeding, inaccurate filling, and reduced packaging efficiency. In severe cases, manual unblocking is required, affecting the continuous operation of the entire production line. A search revealed a raisin bagging anti-clogging device disclosed in existing technology announcement number CN212473973U. This device, through the setting of a first and second screening plate and a connecting pipe, solves the problem of general raisin packaging devices lacking screening function, which affects the overall quality of raisins. Furthermore, it easily leads to clogging during the feeding process. Although this device can separate and screen clumps and sticky raisins during the screening process, if the raisins are not fed in time and become clogged at the discharge port, the separation of clogged raisins can only be achieved through the vibration motor and spring force, resulting in a generally poor unblocking effect. If the blockage cannot be cleared in time, the bagging process will be stopped, affecting bagging efficiency.

[0003] Therefore, existing technologies need further development. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a raisin bag anti-clogging device to solve the technical problem that in related technologies, raisins are not fed in time and get blocked at the discharge port. The blocked raisins can only be separated by the action of a vibration motor and spring, and the unblocking effect is generally poor. If the blockage cannot be cleared in time, it will lead to the cessation of the bagging process and affect the bagging efficiency.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: a raisin bag anti-clogging device is provided, comprising: a screening component having a screening section and a discharge section, the screening section being connected to the discharge section; an air blowing component having an airflow outlet connected to the discharge section; the air blowing component being able to output intermittent airflow into the discharge section.

[0011] Furthermore, it also includes a first bagging assembly, which includes: a first guide pipe, which is connected to the bottom of a first discharge box and extends vertically; a first bagging chamber, which is disposed on a workbench and located below the first guide pipe; a first discharge port is provided at the bottom of the first bagging chamber; and a first limiting plate, which is sleeved on the first guide pipe and is movably disposed relative to the first bagging chamber.

[0012] Furthermore, it also includes a first anti-clogging component, which comprises: two first mounting plates extending along the width direction of the workbench and spaced apart on the screening box along the length direction of the workbench; two first springs corresponding to the two first mounting plates and mounted on the corresponding first mounting plates; and two first flexible balls corresponding to the two first springs and connected to the ends of the corresponding first springs away from the first mounting plates. The two first flexible balls are located on both sides of the first bagging chamber so that when the screening box reciprocates, the two first flexible balls will impact the first bagging chamber.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] According to an embodiment of this utility model, a raisin bag anti-clogging device is provided. Please refer to [link / reference]. Figures 1 to 4It includes: a screening component 1, which has a screening section and a discharge section, and the screening section is connected to the discharge section; an air blowing component 2, whose air outlet is connected to the discharge section; and the air blowing component 2 is capable of outputting intermittent airflow into the discharge section.

[0022] By adopting the above technical solution, and by setting the screening component 1 and the blowing component 2 to work together, the blowing component 2 outputs intermittent airflow to the discharge section, which can effectively break the adhesion and bridging phenomenon formed by raisins in the discharge section and prevent blockage. At the same time, this combination solution ensures the continuity and stability of raisin feeding, improves packaging efficiency, reduces downtime caused by blockage, and thus improves the automation level of the overall production line.

[0023] Please refer to Figure 2 The air blowing assembly 2 includes: an air pipe 3, which is connected to the discharge section; and an air pump, the output end of which is connected to the air pipe 3 to output intermittent airflow into the discharge section through the air pipe 3.

[0024] By adopting the above technical solution, through the cooperation of air pipe 3 and air pump, the air pump outputs intermittent airflow to the discharge section through air pipe 3, which can periodically remove the raisins accumulated in the discharge section and prevent blockage. This airflow output method provides controllable unblocking force, avoids the raisins from sticking together and causing poor flow, ensures the accuracy of filling amount, and reduces maintenance frequency.

[0025] Please refer to Figure 2 and Figure 4 The screening component 1 includes: a screening box 5, which is movably set and has a screening space; a first screen 6, which is set in the screening space and is inclined, and is used to screen raisins; a first discharge box 7, which is installed on the screening box 5 and has a first discharge space that is connected to the screening space, and is used to receive raisins screened by the first screen 6; and an air pipe 3 connected to the first discharge box 7.

[0026] By adopting the above technical solution, through the combination of screening box 5, first screen 6 and first discharge box 7, the inclined design of the first screen 6 promotes the screening and flow of raisins, while the air blowing component 2 is connected to the first discharge box 7, which can promptly clear any possible blockages; this structure realizes the integration of screening and anti-blocking, improves the efficiency and quality of raisin processing, and ensures the continuity of the packaging process.

[0027] Please refer to Figure 2 and Figure 4The screening component 1 further includes: a second screen 8, which is disposed within the screening space and located below the first screen 6. The second screen 8 is inclined and in the opposite direction to the inclination of the first screen 6; a second discharge box 9, which is located on the screening box 5. The second discharge box 9 and the first discharge box 7 are respectively disposed on both sides of the screening box 5. The second discharge box 9 has a second discharge space that is connected to the screening space. The second discharge box 9 is used to receive raisins screened by the second screen 8 and is connected to the air pipe 3. The first discharge box 7 and the second discharge box 9 form a discharge section. The screening box 5, the first screen 6, and the second screen 8 form a screening section.

[0028] By adopting the above technical solution, by setting up a second screen 8 and a second discharge box 9, and forming a multi-stage screening structure with the first screen 6, the screens with different inclination directions ensure the full separation of raisins; at the same time, the air blowing component 2 is connected to the two discharge boxes, which can prevent the blockage of multiple discharge points at the same time, improve the fineness of screening and the comprehensiveness of anti-blockage, thereby improving the reliability and adaptability of the overall device.

[0029] Specifically, the first screen 6 and the second screen 8 have the same shape, but different sieving apertures. The aperture of the first screen 6 is larger than that of the second screen 8. Both the first screen 6 and the second screen 8 have a collection section in the middle. Both sides of the collection section are inclined. When the raisins are being sieved, the raisins that are not sieved will be guided into the collection section through the inclined parts on both sides of the first screen 6 and the second screen 8. Then, the raisins will be poured into the first discharge box 7 and the second discharge box 9 respectively through the inclined first screen 6 and the second screen 8.

[0030] By adopting the above technical solution, through the collection section and inclined sidewall design of the first screen 6 and the second screen 8, raisins are efficiently guided to the collection section and smoothly enter the discharge box, reducing the residue on the screens; at the same time, the screens with different apertures realize the gradient screening of raisins, ensuring the precise separation of particles of different sizes, preventing mixing and clogging, and improving the screening effect and packaging quality.

[0031] Please refer to Figure 1 and Figure 3 It also includes a workbench 10 and a shaking assembly 11, with the shaking assembly 11 and the screening box 5 disposed on the workbench 10; the shaking assembly 11 includes: at least two slide rails 12, each slide rail 12 extending along the length of the workbench 10; at least four pulleys 13, with two pulleys 13 forming a group, each group of pulleys 13 corresponding to each slide rail 12, and each group of pulleys 13 being movably disposed on the corresponding slide rail 12; each group of pulleys 13 is disposed at the bottom of the screening box 5.

[0032] By adopting the above technical solution, the screening box 5 can move smoothly back and forth along the workbench 10 through the cooperation of the slide rail 12 and the pulley 13, which promotes the uniform distribution and flow of raisins on the screen. This shaking mechanism prevents raisins from accumulating and sticking on the screen, improves screening efficiency, and reduces the risk of blockage caused by stillness.

[0033] Furthermore, the pulley 13 can be configured to be connected to the corresponding slide rail 12 in a limiting sliding manner, or the combination of pulley 13 and slide rail 12 can be changed to a combination of slider and slide bar, which also limits the direction of reciprocating movement of the screening box 5. By providing two interchangeable moving pair implementation methods, pulley and slide rail and slider and slide bar, the shaking component 11 is given flexibility in specific structural design, so that the most suitable guiding mechanism can be selected according to different production environments, spatial layouts or cost requirements; this universal design improves the adaptability and manufacturability of the device.

[0034] Please refer to Figure 1 and Figure 2 The shaking assembly 11 further includes: a driving member 14, which is disposed on the worktable 10; a rotating disk 15, which is drivenly connected to the output end of the driving member 14; a first connecting rod 16, which is coaxially disposed with the rotating disk 15; and a second connecting rod 17, which is rotatably connected to the first connecting rod 16 and is rotatably disposed relative to the screening box 5, so as to drive the first connecting rod 16 and the second connecting rod 17 to move through the driving member 14, thereby driving the screening box 5 to reciprocate.

[0035] By adopting the above technical solution, the rotational motion is converted into the linear reciprocating motion of the screening box 5 through the linkage of the driving component 14, the rotating disk 15, the first connecting rod 16 and the second connecting rod 17, thus realizing automatic shaking. This driving method ensures the stability and controllability of the shaking, enhances the screening effect, prevents raisin blockage, and improves the automation level and reliability of the device.

[0036] Specifically, the drive component 14 is a stepper motor. By specifying that the drive component 14 is a stepper motor and clarifying its selection, it can be adjusted according to the load, so that the drive source of the shaking component 11 has high controllability and sufficient torque output capability, which can provide stable and reliable reciprocating motion for the screening box 5. This drive scheme ensures the adjustability of screening force and frequency to adapt to the needs of different material characteristics and processing volume, and enhances the versatility of the device. The motor model can be adjusted according to the actual gears of the screening box 5 and the weight of the raisins to be screened, which is not required here.

[0037] Furthermore, the shaking assembly 11 also includes: a baffle plate mounted on the worktable, located on the side of the screening box 5 away from the drive member 14; multiple rebound springs mounted on the side of the baffle plate near the screening box 5; and a crash plate mounted on the side of the rebound springs away from the baffle plate, with a rubber pad on the side of the crash plate near the screening box 5. When the drive member 16 drives the screening box 5 to move to its furthest distance, the screening box 5 contacts the crash plate to compress it. By setting up a buffer structure consisting of a baffle plate, rebound springs, and a crash plate with a rubber pad, the impact energy of the screening box 5 can be effectively absorbed and buffered when it moves to the end of its stroke. This solution significantly reduces the noise and vibration during equipment operation, protects the screening box 5 and related connecting structures from damage caused by rigid collisions, and extends the service life of the device.

[0038] Please refer to Figure 1 and Figure 4 It also includes a first bagging assembly 18, which includes: a first guide pipe 19, which is connected to the bottom of the first discharge box 7 and extends vertically; a first bagging chamber 20, which is disposed on the workbench 10 and located below the first guide pipe 19; a first discharge port is provided at the bottom of the first bagging chamber 20; and a first limiting plate 21, which is sleeved on the first guide pipe 19 and is movably disposed relative to the first bagging chamber 20.

[0039] By adopting the above technical solution, through the cooperation of the first guide pipe 19, the first bagging chamber 20 and the first limiting plate 21, raisins are smoothly introduced into the packaging bag from the first discharge box 7. The movable design of the first limiting plate 21 is to cooperate with the reciprocating screening box 5 to drive the first guide pipe 19 to move, and to prevent the first guide pipe 19 from falling out of the first bagging chamber 20. This structure ensures the accuracy and smoothness of the bagging process and improves packaging efficiency.

[0040] Please refer to Figure 1 It also includes a first anti-clogging component 22, which includes: two first mounting plates 23, which extend along the width direction of the workbench 10 and are respectively spaced along the length direction of the workbench 10 on the screening box 5; two first springs 24, which are respectively corresponding to the two first mounting plates 23 and are respectively mounted on the corresponding first mounting plates 23; and two first flexible balls 25, which are respectively corresponding to the two first springs 24 and are respectively connected to the end of the corresponding first spring 24 away from the first mounting plate 23. The two first flexible balls 25 are located on both sides of the first bagging chamber 20 so that when the screening box 5 moves back and forth, the two first flexible balls 25 will respectively impact the first bagging chamber 20.

[0041] By adopting the above technical solution, through the combination of the first mounting plate 23, the first spring 24 and the first flexible ball 25, the first flexible ball 25 vibrates when it hits the first bagging chamber 20 when the screening box 5 moves, which can effectively break the bridging or adhesion formed by the raisins in the bagging chamber; this vibration anti-blocking mechanism ensures the continuity of raisin feeding, prevents blockage, and reduces the need for manual intervention.

[0042] Please refer to Figure 1 and Figure 2 It also includes a second bagging assembly 26, which includes: a second guide pipe 27, which is connected to the bottom of the second discharge box 9 and extends vertically; a second bagging bin 28, which is disposed on the workbench 10 and located below the second guide pipe 27; a second discharge port is provided at the bottom of the second bagging bin 28; and a second limiting plate 29, which is sleeved on the second guide pipe 27 and is movably disposed relative to the second bagging bin 28.

[0043] By adopting the above technical solution, the independent bagging process of raisins in the second discharge box 9 is realized through the cooperation of the second guide pipe 27, the second bagging bin 28, and the second limiting plate 29. The movable design of the second limiting plate 29 is to cooperate with the reciprocating screening box 5 to drive the second guide pipe 27 to move, and to prevent the second guide pipe 27 from falling out of the second bagging bin 28. This structure improves the overall packaging capacity, ensures that raisins of different screening grades can be bagged efficiently, and avoids cross-contamination and blockage.

[0044] Specifically, a single air pump is connected to two external air pipes 3 via a connector, which are respectively connected to the first discharge box 7 and the second discharge box 9. When the air pump is started intermittently, airflow can be injected into the first discharge box 7 and the second discharge box 9 through the air pipes 3. The airflow can push out the raisins accumulated at the connection between the first filter screen 6 or the second filter screen 8 and the first discharge box 7 or the second discharge box 9, thus solving the blockage problem. Some airflow can even flow out from the first guide pipe 19 or the second guide pipe 27 to clean the first guide pipe. To further improve the effect, a T-junction can be installed at one end of the air pipe 3 inside the first discharge box 7 and the second discharge box 9 to split the airflow into two paths. One path pushes out the raisins accumulated at the connection between the first filter screen 6 or the second filter screen 8 and the first discharge box 7 or the second discharge box 9. The other path impacts the raisins that have formed bridges in the first guide pipe 19 or the second guide pipe 27 to prevent problems such as raisin accumulation.

[0045] By adopting the above technical solution, through the diversion design of air pipe 3, the airflow is directed to key parts of the discharge box and guide pipe, which can simultaneously handle multiple potential blockage points; this multi-point anti-blockage solution enhances the unblocking effect, ensures the smooth flow of raisins throughout the entire feeding path, and improves the reliability and production efficiency of the device.

[0046] Please refer to Figure 2 and Figure 4 It also includes a second anti-clogging component 30, which includes: two second mounting plates 31 extending along the width direction of the workbench 10 and spaced apart on the screening box 5 along the length direction of the workbench 10; two second springs 32 corresponding to the two second mounting plates 31 and mounted on the corresponding second mounting plates 31; and two second flexible balls 33 corresponding to the two second springs 32 and connected to the ends of the corresponding second springs 32 away from the second mounting plates 31. The two flexible balls 33 are located on both sides of the second bagging chamber 28 so that when the screening box 5 moves back and forth, the two flexible balls 33 will impact the second bagging chamber 28.

[0047] By adopting the above technical solution, through the cooperation of the second mounting plate 31, the second spring 32 and the second flexible ball 33, the second flexible ball 33 vibrates when it hits the second bagging chamber 28 when the screening box 5 moves, which can effectively prevent the raisins in the second bagging chamber 28 from sticking together and bridging; this vibration anti-blocking mechanism works in conjunction with the first anti-blocking component 22 to ensure the smoothness of the entire bagging process and improve the stability and durability of the device.

[0048] Working principle: First, the raisins to be packaged are fed into the screening space of the screening box 5. The shaking component 11 drives the screening box 5 to make a smooth reciprocating motion on the workbench 10. During this process, the drive component 14 converts the rotational motion into the linear reciprocating motion of the screening box 5 through the rotating disk 15, the first connecting rod 16, and the second connecting rod 17. The pulley 13 and the slide rail 12 set at the bottom of the screening box 5 ensure the direction and stability of this movement. The reciprocating shaking of the screening box 5 causes the first screen 6 and the second screen 8, which are arranged in opposite directions inside, to perform multi-stage screening of the raisins. The first screen 6 has a larger aperture and is used to screen larger particles, while the second screen 8 has a smaller aperture and is used to screen smaller particles and defective products. The material collection part in the middle of the two screens and its inclined sidewalls can efficiently guide and collect the raisins that have not been screened and those that have been screened to the first discharge box 7 and the second discharge box 9, respectively. At the same time, to prevent the raisins from getting stuck in the discharge box and below, If a blockage occurs, the air pump directs the airflow through the air pipe 3 and the three-way connector, simultaneously guiding the airflow to the first discharge box 7 and the second discharge box 9. Part of the airflow impacts the connection between the screen and the discharge box to prevent material accumulation, while the other part of the airflow enters the interior of the first guide pipe 19 and the second guide pipe 27 to break any potential material bridging. In addition, the anti-blocking function of the device is further enhanced. The reciprocating motion of the screening box 5 synchronously drives the first anti-blocking component 22 and the second anti-blocking component 30 to work. That is, the first mounting plate 23 and the second mounting plate 31 installed on the screening box 5 move accordingly, and through the first spring 24 and the second spring 32, drive the first flexible ball 25 and the second flexible ball 33 to periodically impact the first bagging bin 20 and the second bagging bin 28. The resulting vibration effectively prevents the raisins from sticking and blocking in the bagging bin, ensuring the efficient, continuous and stable operation of the entire process from screening to bagging of raisins.
