Description

Technical Field

[0001] The present invention relates to the technical field of air separation, and particularly relates to a label blowing machine and a cleaning method for peeling labels from packaging bottles. Background Art

[0002] A packaging bottle is a type of packaging container in the packaging industry. After the contents in the packaging bottle are used, the packaging bottle is generally discarded as waste or garbage. In contemporary society, more and more attention is paid to environmental protection and resource conservation. Therefore, many packaging bottles are now recycled and reprocessed into new products. Recycling packaging bottles requires peeling the labels on the bottle body to ensure the purity of the packaging bottle material and the quality of the new products made from the packaging bottles. If the labels are peeled off from the intact bottle body, it is necessary to tear off the labels one by one, which is time-consuming and laborious, and the peeling is difficult. The existing technology directly crushes the packaging bottles. The crushed packaging bottle fragments include crushed label papers, and then the fragments are subjected to air separation to separate the label papers with lighter quality and the packaging bottle fragments with heavier quality.

[0003] The existing air separation device separates the label papers of packaging bottles. Since there needs to be an outlet for the gas to flow out in the structure for blowing the label papers into, an exhaust net is generally provided, which can prevent the label papers from flying out and can also exhaust the air. However, because the label papers are small in volume and lighter in quality after being broken, they are easily attached to the exhaust net or the equipment for discharging the label papers. After long-term accumulation, not only will the discharge of gas be blocked, and the gas will be left in the device, affecting the air separation effect; the label papers on the exhaust net are difficult to clean, and the other equipment for discharging the label papers will also be difficult to discharge due to the attachment of the label papers. On the other hand, in order to increase the air separation effect and accelerate the discharge of the packaging bottle fragments, it is necessary to provide a structure for rotating and supporting the air separation structure.

[0014] To achieve the above object, the present invention also provides a method for cleaning the label of a packaging bottle based on the above label blowing machine for peeling the label of a packaging bottle. The innovation lies in: specifically including the following steps: S1. Air separation preparation: Start the drive motor to indirectly drive the air separation rotary drum part to rotate. Start the air separation fan to supply air to the air separation rotary drum part and the cleaning box. Start the guiding fan to blow the guiding vanes near the inside to move downward, that is, make each guiding vane rotate downward through the guiding fan. Install the exhaust plate between two connecting plates from top to bottom by clamping it into the card slot with the card strip, and perform upper limit positioning with the limit plate. S2. Air separation: Feed the packaging bottle fragments containing labels from the feed inlet. The material enters the air separation rotary drum part from the feed inlet. Due to the inclination and rotational setting of the air separation rotary drum part, during the feeding process and the rotation process with the air separation rotary drum part, the lighter label paper is blown into the cleaning box by the air separation fan, and the heavier packaging bottle fragments gradually move downward with the rotation of the air separation rotary drum part and finally are discharged from the bottle fragment discharge port. S3. Label guiding: Part of the label paper blown into the cleaning box by the air separation fan impacts the side of the cleaning box far from the air separation rotary drum part and directly enters the discharge funnel. Part of it moves to both sides of the cleaning box with the wind direction and enters between the guiding vanes. Driven by the blowing of the guiding fan, the label paper entering each guiding vane rotates downward with the guiding vane and finally falls into the discharge funnel under the action of centrifugal force and gravity. The air is discharged through the exhaust net. S4. Label discharge: The label paper entering the discharge funnel falls downward to the bottom of the label elevator. For the label paper attached to the inclined plane with the smallest inclination angle of the discharge funnel, start the discharge motor to drive the discharge scraper to rotate. Scrape the label paper downward through the discharge scraper and the scraping brush arranged on its surface and discharge it to the bottom of the label elevator. The label paper entering the label elevator is lifted and processed by other equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the label blowing machine for peeling labels from packaging bottles of the present invention, the air separation mechanism and the label cleaning mechanism are rotationally connected, and then the air separation mechanism is driven by a driver to rotate to perform air separation on the material. The air-separated label paper is blown into the label cleaning mechanism. The label paper is guided into the label discharging mechanism through the label guiding device, and the clean gas filtered by the label guiding device is discharged through the exhaust device, ensuring efficient cleaning and discharge of the label and avoiding the difficulty of cleaning the label attached to the exhaust device.

[0016] The method for cleaning labels on packaging bottles of the present invention quickly performs air separation, guiding separation and discharge on the label paper. The air separation efficiency is high and the effect is good. The label paper is guided and discharged to avoid the problems of affecting gas discharge due to attachment and difficult cleaning and discharge caused by label attachment.

The air separation mechanism 3 includes an air separation rotating cylinder part 31 and an air separation driving part 32 with an inner diameter smaller than that of the air separation rotating cylinder part 31; a driver 6 is also arranged on the support plate 1, and the driver 6 is connected to the air separation rotating cylinder part 31 in the air separation mechanism 3, and the air separation rotating cylinder part 31 is driven to rotate by the driver 6.

[0030] A bottle chip discharging port 7 is arranged at the lower inclined part of the air separation mechanism 3; a feeding port 8 is arranged on the label cleaning mechanism, and the feeding port 8 communicates with the inside of the air separation mechanism 3; an exhaust device 41 and a label guiding device 42 are arranged inside the label cleaning mechanism 4, and the label discharging mechanism 5 is connected and arranged below the label cleaning mechanism 4.

[0031] In this embodiment, the air separation mechanism 3 and the label cleaning mechanism 4 are connected, and then the air separation rotating cylinder part of the air separation mechanism 3 is driven by the driver 6 to rotate to perform air separation on the materials. The label paper after air separation is blown into the interior of the label cleaning mechanism 4, and the label paper is guided into the label discharging mechanism 5 through the label guiding device 42, and the clean gas filtered by the label guiding device 42 is discharged through the exhaust device 41, ensuring efficient discharge of label cleaning and avoiding difficulty in cleaning the label attached to the exhaust device 41.

[0032] Embodiment 2: Based on the above embodiment, the support mechanism 2 of this embodiment includes two first support members 211 and second support members 212 both in the shape of lying E. The first support member 211 is higher than the second support member 212. The first support member 211 is arranged at the inclined lower end of the support plate 1, and the second support member 212 is arranged below the inclined upper part of the support plate 1. A support leg 22 is also provided on the second support member 212 to connect to the support plate 1. The top ends of both ends of the first support member 211 are respectively connected to the top ends of both ends of the second support member 212 through inclined rods 23, and the two inclined rods 23 are arranged in parallel; two reinforcing rods 24 are also provided below each inclined rod 23. One ends of the two reinforcing rods 24 are connected to the middle part of the inclined rod 23, and the other ends are respectively connected to the corresponding vertical parts of the first support member 211 and the second support member 212.

[0033] The two reinforcing rods 24, the inclined rod 23, and the corresponding vertical parts of the first support member 211 or the second support member 212 form a triangular shape, improving the support ability and the overall structural stability of the device.

[0034] Embodiment 3: Based on the above embodiment, the axial direction of the air separation rotating cylinder part 31 is parallel to the inclined direction of the support plate 1; as Figure 1 and 7 shown, both ends of the air separation rotating cylinder part 31 are connected to the label cleaning mechanism 4 and the air separation driving part 32 through rotating connectors 33, and are respectively communicated with the label cleaning mechanism 4 and the air separation driving part 32. The driver 6 is in transmission connection with the air separation rotating cylinder part 31; a filter screen 34 is provided at the end of the air separation driving part 32 far from the air separation rotating cylinder part 31, and an air separation fan 35 is also provided inside the air separation driving part 32; several bottle piece discharge ports 7 are evenly arranged along the circumference at the inclined lower end of the side of the air separation rotating cylinder part 31; a support member 36 is provided at the bottom of the air separation driving part 32.

[0035] In this embodiment, both ends of the air separation rotating cylinder part 31 are respectively connected to the label cleaning mechanism 4 and the air separation driving part 32. During use, the air separation rotating cylinder part 31 is driven by the driver 6 to rotate to perform rotational conveyance on the materials, and air separation is performed by blowing air through the air separation driving part 32 during the conveyance process. This not only supports the air separation rotating cylinder part 31 but also ensures its rotation, and the air separation fan 35 can be arranged inside the air separation driving part 32 to avoid its rotation with the air separation rotating cylinder part 31 affecting the power supply to it.

[0036] Embodiment 4. Based on the above embodiment, the driver 6 of this embodiment includes a drive motor 61, a transmission shaft 62, a driving gear 63, a driven gear 64, a drive shaft 65 and two main rotating gears 66. As Figure 1 shown, the drive motor 61 is arranged on the support plate 1, the transmission shaft 62 is in transmission connection with the drive motor 61, the drive shaft 65 is arranged parallel to the air separation rotating cylinder part 31, the driven gear 64 and the two main rotating gears 66 are both fixedly sleeved on the drive shaft 65, and the driving gear 63 meshes with the driven gear 64; corresponding to the two main rotating gears 66 on the air separation rotating cylinder part 31, driven rotating gears 67 are respectively fixed, and the two main rotating gears 66 respectively mesh with the corresponding driven rotating gears 67; five support bearing seats 68 are further arranged on the support plate 1, one of the support bearing seats 68 is sleeved on the transmission shaft 62, and the remaining support bearing seats 68 are grouped in pairs, and each group is respectively sleeved on the drive shaft 65 on both sides of the corresponding main rotating gear 66. The transmission shaft 62 and the drive shaft 65 can rotate in the corresponding support bearing seats 68.

[0037] In this embodiment, the drive motor 61 is started, so that the transmission shaft 62 rotates, and through the meshing of the driving gear 63 and the driven gear 64, the drive shaft 65 rotates, and then the rotation is transmitted to the air separation rotating cylinder part 31 through the main rotating gear 66 and the driven rotating gear 67 to drive the air separation rotating cylinder part 31 to perform conveying and air separation. The support bearing seats 68 in this embodiment support the transmission shaft 62 and the drive shaft 65, improving the driving stability of the driver 6.

[0038] Embodiment 5. Based on the above embodiment, the label cleaning mechanism 4 of this embodiment includes a cubic cleaning box 43, and the number of the exhaust devices 41 and the label guiding devices 42 is both two. The two exhaust devices 41 are detachably arranged on both sides of the label cleaning box 43, and the two label guiding devices 42 are correspondingly arranged inside the two exhaust devices 41 of the cleaning box 43. An inlet 8 is arranged at the top of the cleaning box 43. The inlet 8 is in the shape of an inverted right-angled trapezoid, and the side corresponding to the hypotenuse is far away from the air separation mechanism 3. The side corresponding to the hypotenuse of the inlet 8 extends into the upper part inside the air separation rotating cylinder part 31 according to the original inclination angle.

[0039] The side corresponding to the hypotenuse of the inlet 8 extends to the air separation rotating cylinder part 31, which can directly convey the materials into the air separation rotating cylinder part 31, avoiding placing them in the cleaning box 43 so that the packaging bottle fragments enter the label discharging mechanism 5 and are discharged, resulting in incomplete separation.

[0040] Embodiment 6. Based on the above embodiment, in order to better guide the label downward into the label discharging mechanism 5, the label guiding device 42 of this embodiment includes several guiding rods 421 arranged vertically on the inner side surface of the cleaning box 43, and a guiding sleeve 422 is rotatably sleeved on each guiding rod 421. As Figure 5 and 6As shown in the figure, guide vanes 423 are evenly arranged along the circumference on the guide sleeve 422. The shortest distance that can be approached between the guide vanes 423 on two adjacent guide sleeves 422 is 1 - 3 mm. The label guiding device 42 further includes a guiding fan 424. The guiding fan 424 is arranged on the top of the cleaning box 43, and the air outlet is aligned inwardly with the guide vanes 423 located inside the guide rod 421. The inner side of this position is centered on the center of the cleaning box 43, that is, the air outlet of the guiding fan 424 corresponds to the side of the guide rod 421 close to the center of the cleaning box 43.

[0041] In this embodiment, the shortest distance that can be approached between the guide vanes 423 on two adjacent guide sleeves 422 is 1 - 3 mm. This description specifically means that for two adjacent guide sleeves 422 above and below, when the guide vane 423 on the upper guide sleeve 422 rotates to the lowermost end and the guide vane 423 on the lower guide sleeve rotates to the uppermost end, the two closest guide vanes 423 do not touch, and the distance between the two closest guide vanes 423 is 1 - 3 mm.

[0042] In this embodiment, the materials of the guide sleeve 422 and the guide vanes 423 can be selected as plastic or other materials with lighter mass. By blowing the guide vanes 423 on each guide sleeve 422 with the guiding fan 424, the guide vanes 423 rotate downward, and the labels placed between the guide vanes 423 are discharged downward into the label discharging mechanism 5, which is efficient and convenient for cleaning the labels. It avoids the problems that the labels adhere to the exhaust device 41 and are difficult to clean and affect the air outlet.

[0043] Embodiment 7, based on the above embodiment, in order to facilitate the disassembly of the exhaust device, the exhaust device 41 of this embodiment includes an exhaust plate 411. On both sides of the side of the cleaning box 43 corresponding to the exhaust device 41, connecting plates 412 are respectively arranged outward. The exhaust plate 411 is placed between the two connecting plates 412, and clamping strips 413 are respectively arranged at both ends. The two connecting plates 412 are respectively provided with clamping grooves 414 corresponding to the two clamping strips 413, and the clamping strips 413 are clamped in the clamping grooves 414. It also includes two limiting columns 415. The two limiting columns 415 are arranged at the top of the cleaning box 43 near the ends corresponding to the exhaust plate 411. A limiting disc 416 is arranged at the top of the limiting column 415. As Figure 2 shown in the figure, a limiting plate 417 is rotatably sleeved on the limiting column 415, and the rotation of the limiting plate 417 is limited to the top of the exhaust plate 411. The exhaust plate 411 is provided with an exhaust net 418 corresponding to the whole formed by all the guide vanes 423 of the label guiding device 42 on its inner side. That is, the area size and the setting position of the exhaust net 418 correspond to the whole area and position formed during the rotation of all the guide vanes 423 on the guide sleeves 422, or it can be larger than the whole area formed during the rotation of the guide vanes 423, so that the guide vanes 423 and the guide sleeves 422 can completely block the exhaust net 418, avoiding the attachment of the label paper to the exhaust net 418 along with the gas.

[0044] In this embodiment, the exhaust plate 411 is detachably arranged on the cleaning box 43, which is convenient for replacement and maintenance, flexible and convenient to use. Moreover, through the label guiding device 42, it is possible to avoid the problem that the label paper adheres to the exhaust device 41, affecting the air outlet and being difficult to clean.

[0045] Embodiment 8, based on the above embodiment, the rotating connecting piece 33 of this embodiment includes a connecting ring piece 331. As Figure 7 and 8 shown, connecting ring pieces 331 are provided both on the part where the cleaning box 43 is connected to the air separation rotating cylinder part 31 and on the part where the air separation rotating cylinder part 31 is connected to the air separation driving part 32. The connecting ring piece 331 is provided with an annular groove 332 inward. The end of the air separation rotating cylinder part 31 close to the cleaning box 43 and the end of the air separation driving part 32 close to the air separation rotating cylinder part 31 are respectively rotatably placed in the annular groove 332 of the corresponding connecting ring piece 331.

[0046] The setting of the connecting ring piece 331 not only supports the air separation rotating cylinder part 31 but also ensures its rotation, improving the efficiency and quality of air separation and conveying.

[0047] Embodiment 9, based on the above embodiment, the label discharging mechanism 5 of this embodiment includes a discharging funnel 51 formed by four faces corresponding to the cleaning box 43 and a label elevator 52. As Figure 3 shown, the upper end of the discharging funnel 51 is communicated with the lower end of the cleaning box 43. The discharging port of the discharging funnel 51 is close to one side below the cleaning box 43. The feeding end of the label elevator 52 is arranged below the discharging funnel 51 and communicated with the discharging port of the discharging funnel 51. The label elevator 52 is arranged obliquely upward, and the other side below the cleaning box 43 is supported by a fixed column 53.

[0048] A discharging motor 54 is provided at the outer center of the inclined surface with the smallest inclination angle of the discharging funnel 51. As Figure 3 and 4 shown, the discharging motor 54 is internally driven with a discharging shaft 55. A discharging sleeve 56 is fixedly sleeved on the discharging shaft 55. Two symmetric discharging scraping plates 57 are fixedly arranged on the discharging sleeve 56, and scraping brushes 58 are evenly arranged on the discharging scraping plates 57.

[0049] In this embodiment, the discharging funnel 51 is provided with four faces corresponding to the cleaning box 43, and the discharging port is located at one end below the cleaning box 43. Then, the side surface of the discharging funnel 51 corresponding to the other end of the cleaning box 43 away from the discharging port of the discharging funnel 51 will increase, and the inclination angle will be much smaller than that of other inclined surfaces. The probability of the label paper adhering during the discharging process on this inclined surface will increase. Therefore, a discharging motor 54 and discharging scraping plates 57 are provided on this inclined surface, etc., which can efficiently discharge the label paper by rotating the discharging scraping plates 57, solving the problem that the label paper is difficult to discharge.

[0050] The lifting mechanism in this embodiment can be a spiral hoist, which is a prior art and the specific structure will not be described here in the present invention.

[0051] Example 10: This embodiment provides a method for cleaning bottle labels based on the above-mentioned bottle label stripping blowing machine, as described above. Figure 9 As shown, the specific steps include: S1. Preparing for air separation: Start the drive motor 61, indirectly driving the air separation drum 31 to rotate. Start the air separation fan 35 to deliver air to the air separation drum 31 and the cleaning box 43. Start the guide fan 424 to move the guide blades 423 near the interior downward. The guide fan 424 causes the guide blades 423 to rotate downward. Install the exhaust plate 411 from top to bottom between the two connecting plates 412 by inserting the clip 413 into the slot 414. The upper limit is secured by the limit plate 417. S2. Air separation: Bottle fragments containing labels are fed from feed port 8 and enter the air separation drum 31. Because the drum 31 is tilted and rotates, during the unloading process and as the drum 31 rotates, the lighter labels are blown by the air separation fan 35 into the cleaning box 43. The heavier bottle fragments gradually move downward as the drum 31 rotates and are ultimately discharged from the bottle flake discharge port 7. S3. Label Guidance: Labels blown into the cleaning box 43 by the air separation blower 35 partially strike the side of the cleaning box 43 away from the air separation drum 31 and enter the discharge hopper 51 directly. Others follow the wind's direction and move toward the sides of the cleaning box 43, entering between the guide blades 423. Driven by the guide blower 424, the labels within each guide blade 423 rotate downward, eventually falling into the discharge hopper 51 due to centrifugal force and gravity. The air is then discharged through the exhaust screen 418. S4. Label discharge: The labels entering the discharge hopper 51 fall downward to the bottom of the label elevator 52. The labels attached to the inclined surface of the discharge hopper 51 with the smallest inclination angle are driven by the discharge motor 54 to rotate the discharge scraper 57. The discharge scraper 57 and the scraping brush 58 on its surface scrape the labels downward to the bottom of the label elevator 52. The labels entering the label elevator 52 are then lifted and sent to other equipment for processing.

10. A method for cleaning a label of a packaging bottle, characterized in that: The cleaning method is realized by the above-mentioned label blowing machine and specifically includes the following steps: S1. Air separation preparation: Start the driving motor to indirectly drive the air separation rotary drum part to rotate. Start the air separation fan to supply air into the air separation rotary drum part and the cleaning box. Start the guiding fan to blow the guide pieces close to the inside to move downward, that is, make each guide piece rotate downward through the guiding fan. Install the air exhaust plate between the two connecting plates from top to bottom by clamping the clamping strips into the clamping grooves, and perform upper limit positioning through the limiting plate. S2. Air Separation: The packaging bottle fragments with labels are fed from the feed inlet. The material enters the air separation rotating drum part from the feed inlet. Due to the inclination and rotational setting of the air separation rotating drum part, during the feeding process and the rotation of the air separation rotating drum part, the relatively light label paper is blown into the cleaning box by the air separation fan, and the relatively heavy packaging bottle fragments gradually move downward with the rotation of the air separation rotating drum part and are finally discharged from the bottle fragment discharge port.

Driven by the guiding fan, the label paper entering each guiding sheet rotates downward with the guiding sheet and finally falls into the discharge funnel under the action of centrifugal force and gravity. The air is discharged through the exhaust net. S4. Label Discharge: The label paper entering the discharge funnel falls downward to the bottom of the label elevator. For the label paper attached to the inclined surface with the smallest inclination angle of the discharge funnel, by starting the discharge motor, the discharge scraper is driven to rotate. The label paper is scraped downward by the discharge scraper and the scraping brush arranged on its surface and discharged to the bottom of the label elevator. The label paper entering the label elevator is lifted and processed by other equipment.
