Description

Technical Field

[0001] The invention relates to the technical field of paint bucket recycling and processing equipment, in particular to an integrated system for cleaning the inside and outside of a closed bucket. Background Art

[0002] There are generally several ways to recycle and process waste paint metal barrels. One is to clean and process the metal barrels into plate-like structures by cutting or crushing. The other is to directly clean and refurbish the closed metal barrels as a whole. Among them, the refurbishment of such closed metal barrels is generally carried out by manual or complex cleaning equipment. The processing process is complicated and cumbersome, and the equipment cost is high and the refurbishment efficiency is low, which increases the recycling cost of such closed barrels. Specifically, for the surface paint layer of paint metal barrels, the traditional method of removing by burning or solvent is not environmentally friendly, and the method of removing paint by shot blasting is very harmful to the outer surface of the barrel, making it rough, dark and not smooth. The above series of problems have caused some manufacturers to not use cleaning and refurbishment to recycle metal barrels due to factors such as cost and recycling difficulty, which has caused great resistance and adverse effects on the green environmental protection and recycling concepts advocated today.

[0005] Furthermore, the barrel body cleaning mechanism includes a supporting wheel, a driving wheel and a barrel body grinding roller brush, wherein the supporting wheel extends parallel to the axial direction of the metal barrel, the driving wheel is divided into a plurality of sections and each section of the driving wheel is arranged obliquely along the axial outside of the metal barrel, the supporting wheel and the driving wheel jointly support the metal barrel and the driving wheel drives the lying metal barrel to make a directional rotation forward along the axial direction; the barrel body grinding roller brush abuts against and grinds the outer surface of the metal barrel, and the barrel body grinding roller brush and the metal barrel rotate in opposite directions.

[0006] Furthermore, the end cover cleaning mechanism includes a first drive component and two end cover grinding roller brushes symmetrically arranged on both sides of the first drive component, wherein the first drive component is used to carry and convey the horizontally placed metal barrel for rolling forward, and the two end cover grinding roller brushes respectively abut and grind the outer surfaces of the upper end cover and the lower end cover, and the end cover grinding roller brushes are extended along the rolling forward direction of the metal barrel at the end cover cleaning mechanism.

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention is described more fully below with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. The purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly and comprehensively understood.

[0025] See attached Figure 1 To Attachment Fig.11 As shown, a closed barrel internal and external cleaning integrated system is used to process the internal and external surfaces of a closed metal barrel (A) to clean and remove surface materials such as paint layers and trademark layers. The system includes a barrel body cleaning mechanism 100, an end cover cleaning mechanism 200 and a tilting cleaning mechanism 300 arranged in sequence along the conveying direction, wherein the inner cavity of the metal barrel A is pre-filled with abrasives and the metal barrel A is cleaned in sequence by the barrel body cleaning mechanism 100, the end cover cleaning mechanism 200 and the tilting cleaning mechanism 300.

[0026] See attached Figure 2 and 3As shown, in this embodiment, the barrel cleaning mechanism 100 is used to drive the horizontal metal barrel A to rotate and move forward in a directional manner along its axial direction, and to grind and clean the outer surface of the barrel body during the directional forward movement of the metal barrel A, wherein the barrel cleaning mechanism 100 of this embodiment includes a support wheel 110, a drive wheel 120 and a barrel body grinding roller brush 130, wherein the support wheel 110 extends in parallel to the axial direction of the metal barrel A, the drive wheel 120 is divided into a plurality of sections and each section of the drive wheel 120 is arranged obliquely toward the outside of the axial direction of the metal barrel A, so that a plurality of sections of the drive wheel 120 are in contact with the metal barrel A to generate an oblique forward force on the metal barrel A, which is then converted into a torque for the metal barrel A to rotate and a thrust for the axial forward translation, and each section of the drive wheel 120, under the premise of a constant rotation speed, can adjust the position of the metal barrel A in the barrel body by changing the angle between the drive wheel 120 and the axial direction of the metal barrel A (the larger the angle between the drive wheel 120 and the metal barrel A, the greater the thrust in the axial direction). The rotation speed and feed speed at the cleaning mechanism 100 are inversely proportional to each other, that is, the greater the rotation angular velocity, the slower the feed speed, and vice versa, the slower the rotation angular velocity, the faster the feed speed; thus, the metal barrel A is supported by the support wheel 110 and a plurality of driving wheels 120, and the driving wheel 120 drives the lying metal barrel A to rotate and move forward in an axial direction; the barrel body grinding roller brush 130 is arranged at an oblique upper position of the support wheel 110. The axis of the barrel body grinding roller brush 130 extends parallel to the axis of the metal barrel A, so that the barrel body grinding roller brush 130 rotating at high speed is used to abut and grind the outer surface of the metal barrel A. The barrel body grinding roller brush 130 and the metal barrel A rotate in opposite directions. Thus, multiple metal barrels A are placed horizontally and sent into the barrel body cleaning mechanism 100 in sequence. Each metal barrel A rotates forward in a directional manner along the axial direction, and the outer surface of the barrel body of the metal barrel A is polished by the barrel body grinding roller brush 130 during the rotation and forward movement.

[0027] Furthermore, the barrel body grinding roller brush 130 and the driving wheel 120 of this embodiment are driven by a preset external driving motor (in the figure), and its transmission structure belongs to conventional technical means and is not limited here.

[0028] Furthermore, the forward rotation distance, rotation speed, grinding and cleaning time of the barrel cleaning mechanism 100 can be adjusted accordingly according to the actual condition of the metal barrel A being processed.

[0029] In this embodiment, the end cap cleaning mechanism 200 is used to drive the horizontal metal barrel A to roll forward in the radial direction, and to grind and clean the outer surfaces of the upper and lower end caps during the rolling forward of the metal barrel A. Specifically, the end cap cleaning mechanism 200 includes a first driving component and two end cap grinding roller brushes 230 symmetrically arranged on both sides of the first driving component, wherein the first driving component is used to carry and convey the horizontal metal barrel A to roll forward, and the first driving component of this embodiment includes the following two implementation modes:

[0030] See attached Figure 4 and 6 As shown, the first embodiment of the first driving component is as follows: the first driving component includes an upper conveying unit 210 and a lower conveying unit 220 arranged in an upper and lower manner, wherein the conveying direction of the upper conveying unit 210 is opposite to and unequal to the conveying direction of the lower conveying unit 220; the combined speed direction of the upper conveying unit 210 and the lower conveying unit 220 is the rolling forward direction of the metal barrel A at the end cover cleaning mechanism 200, and the upper conveying unit 210 and the lower conveying unit 220 act on the upper and lower ends of the barrel body respectively to make the metal barrel A rotate and roll forward radially at the same time. For ease of understanding, the conveying direction of the lower conveying unit 220 is defined as the forward direction, and the conveying speed of the upper conveying unit 210 is the backward direction. The speed of the lower conveying unit 220 is faster than that of the upper conveying unit 210, so that the horizontally placed metal barrel A is radially rolled to between the upper conveying unit 210 and the lower conveying unit 220, and the horizontally placed metal barrel A is clamped by the upper conveying unit 210 and the lower conveying unit 220 together to make the metal barrel A roll forward forward.

[0031] See attached Figure 5 and 7 As shown, the second embodiment of the first driving component: the first driving component includes a single conveying unit 240 arranged in an upper and lower manner and a supporting portion 250 for supporting the metal barrel A, wherein the supporting portion 250 is a supporting channel for the metal barrel A to roll, and the single conveying unit 240 is a forward conveying direction, and the horizontally placed metal barrel A rolls between the single conveying unit 240 and the supporting portion 250, and the single conveying unit 240 acts on the upper end of the barrel body to make the metal barrel A rotate while rolling forward radially.

[0032] In addition, the two end cover grinding roller brushes 230 respectively abut against and grind the outer surfaces of the upper end cover and the lower end cover, and the axis of the end cover grinding roller brush 230 is extended along the rolling forward direction of the end cover cleaning mechanism 200. The two high-speed rotating end cover grinding roller brushes 230 are used to grind and clean the outer surfaces of the upper end cover and the lower end cover at both ends of the metal barrel A driven by the first driving component, and at this time, the two end cover grinding roller brushes 230 rotate in opposite directions.

[0033] Furthermore, the axial length of the roller surface of the end cap grinding roller brush 230 of this embodiment is at least half of the outer circumference of the upper and lower end caps, that is, the axial length of the roller surface of the end cap grinding roller brush 230 is at least the distance of half a rotation of the upper and lower end caps driven by the first driving component, thereby ensuring that the entire outer surface of the upper and lower end caps can be polished and cleaned; and in actual production, in order to ensure the effect of polishing and cleaning, the axial length of the roller surface of the end cap grinding roller brush 230 can be appropriately extended so that the upper and lower end caps can rotate multiple circles relative to the end cap grinding roller brush 230 and perform multiple polishing treatments to improve the polishing effect. Not only the above-mentioned method of appropriately increasing the axial length of the roller surface of the end cap grinding roller brush 230 can be adopted. The driving speed of the first driving component can also be changed to adjust the grinding coordination time between the metal barrel A and the end cover grinding roller brush 230 accordingly, that is, when the driving speed of the first driving component is faster, the conveying speed of the metal barrel A is faster, the grinding coordination time of the end cover grinding roller brush 230 is shorter, and the grinding and cleaning effect is general; conversely, when the driving speed of the first driving component is slower, the conveying speed of the metal barrel A is slower, the grinding coordination time of the end cover grinding roller brush 230 is longer, and the grinding and cleaning effect is better.

[0034] In this embodiment, the conveying direction of the metal barrel A at the barrel body cleaning mechanism 100 is arranged perpendicularly to the conveying direction of the metal barrel A at the end cap cleaning mechanism 200, so that the barrel body cleaning mechanism 100 and the end cap cleaning mechanism 200 are arranged perpendicularly and a corner is provided between the two, and the metal barrel A delivered by the barrel body cleaning mechanism 100 is rolled and pushed into the end cap cleaning mechanism 200 by manual or external auxiliary cylinder push rod (not shown in the figure). In addition, the metal barrel A is in a horizontal rotation form between the barrel body cleaning mechanism 100 and the end cap cleaning mechanism 200, so that the abrasive particles in its inner cavity can grind and clean the inner wall along with the rotation of the metal barrel A.

[0035] Furthermore, the upper conveying unit 210, the lower conveying unit 220 and the single conveying unit 240 are transmission belts with two symmetrically arranged transmission rubber strips (that is, two transmission rubber strips are fixed on the transmission belt, and the transmission rubber strips are in friction contact with the surface of the metal barrel A). Secondly, in order to prevent the metal barrel A from slipping out and falling during the processing of the first driving component, a protruding structure can be formed on the outer edge of the above-mentioned transmission rubber strip, and the protruding structure is used to cooperate with the edge of the metal barrel A to achieve the effect of limiting and positioning.

[0036] See attached Figure 1 and 8As shown, in the present embodiment, the tilting cleaning mechanism 300 is used to drive the horizontally placed metal barrel A to roll forward along its radial direction, and drive the metal barrel A to tilt and swing regularly during the rolling forward movement, so that the abrasive grinds the inner walls of the upper end cover and the lower end cover. Specifically, the tilting cleaning mechanism 300 of the present embodiment includes a first tilting conveying unit 310, a second tilting conveying unit 320 and a third tilting conveying unit 330 which are arranged end to end in sequence, that is, the outlet of the first tilting conveying unit 310 is closely connected with the inlet of the second tilting conveying unit 320, and the outlet of the second tilting conveying unit 320 is closely connected with the inlet of the third tilting conveying unit 330, so that the metal barrel A can pass through the above-mentioned first tilting conveying unit 310, the second tilting conveying unit 320 and the third tilting conveying unit 330 in sequence.

[0037] See attached Fig. 9 As shown, in the present embodiment, the conveying surface of the first tilting conveying unit 310 gradually and smoothly tilts from a horizontal plane toward one side along its conveying direction to a first rated inclination angle (for the convenience of explanation, the first rated inclination angle is preferably defined as 45°, without specific limitation). The first tilting conveying unit 310 is defined here as being smoothly tilted toward the left side and the left side of the corresponding metal barrel A is the upper end cover (the specific positions of the upper end cover and the lower end cover are not limited here, only for the convenience of explanation). At this time, the lying metal barrel A is sent into the first tilting conveying unit 310. While the metal barrel A is gradually rolled forward in the radial direction along the conveying surface of the first tilting conveying unit 310, the metal barrel A is gradually tilted toward the left side from the horizontal lying state, so that the abrasive in the inner cavity is gradually deposited downward on the left side of the metal barrel A, so that the abrasive grinds and cleans the inner surface of the upper end cover of the rotating metal barrel A.

[0038] See attached Fig.10 As shown, in this embodiment, the conveying surface of the second tilting conveying unit 320 gradually and smoothly tilts from a first rated inclination angle (for the sake of convenience of explanation, the first rated inclination angle is preferably defined as 45°, without specific limitation) to the other side along its conveying direction to a horizontal plane. The second tilting conveying unit 320 is defined here as being smoothly inclined toward the right side. At this time, the metal barrel A lying at an angle is transferred from the first tilting conveying unit 310 to the second tilting conveying unit 320. While the metal barrel A is gradually rolled forward in the radial direction along the conveying surface of the second tilting conveying unit 320, the metal barrel A is gradually leveled to the right from the inclined state. At this time, the abrasive deposited on the left side of the metal barrel A will continue to grind and clean the inner surface of the upper end cover, and the abrasive will gradually transfer to the right side.

[0039] See attached Fig.11As shown, in the present embodiment, the conveying surface of the third tilting conveying unit 330 gradually and smoothly tilts from the horizontal plane toward the other side along its conveying direction to the second rated inclination angle (for the convenience of explanation, the second rated inclination angle is preferably defined as 90° without specific limitation). The third tilting conveying unit 330 is defined here as being smoothly inclined toward the right side and the right side of the corresponding metal barrel A is the lower end cover. At this time, the horizontally lying metal barrel A is transferred from the second tilting conveying unit 320 to the third tilting conveying unit 330. While the metal barrel A is gradually rolled forward radially along the conveying surface of the third tilting conveying unit 330, the metal barrel A gradually tilts to the right from the horizontal lying state. At this time, the abrasive in the inner cavity of the metal barrel A will gradually deposit on one side of the lower end cover to grind and clean the inner surface of the lower end cover until the metal barrel A is swung to 90° and sent out of the third tilting conveying unit 330, so that the metal barrel A is finally placed vertically, which is more convenient for subsequent storage, processing and other work.

[0040] Furthermore, the metal barrel A rotates and swings during the tilting and cleaning mechanism 300, and the abrasive particles in its inner cavity also grind and clean the inner wall of the barrel.

[0041] To summarize, the metal barrel A is rolled through the first tilting conveying unit 310, the second tilting conveying unit 320 and the third tilting conveying unit 330 in sequence, so that the metal barrel A is gradually tilted from horizontal lying to the first rated inclination angle, and then gradually tilted from the first rated inclination angle to horizontal lying, and finally gradually tilted from horizontal lying to the second rated inclination angle, wherein, as the metal barrel A tilts and swings, the abrasive is used to grind and clean the inner walls of the upper end cover, the lower end cover and the inner wall of the barrel body respectively.

[0042] Furthermore, the specific amount of abrasives filled in the inner cavity of the metal barrel A in this embodiment is related to the specifications of the metal barrel A. The larger the specifications of the metal barrel A, the greater the amount of abrasives used. Conversely, the smaller the specifications of the metal barrel A, the smaller the amount of abrasives used. In addition, the grinding amount of the abrasive grains on the inner wall of the metal barrel A at the tilting cleaning mechanism 300 can be controlled according to actual production requirements, and there is no need to excessively require precise control of the relationship between the abrasive grains and the metal barrel A. It is only necessary to appropriately increase the conveying distance of the first tilting conveying unit 310, the second tilting conveying unit 320 and the third tilting conveying unit 330 to ensure that the abrasive grains are in contact with the inner surfaces of the upper and lower end covers of the metal barrel A as much as possible, that is, when the grinding and cleaning requirements are high, the conveying distance is set to be long, and vice versa, when the grinding and cleaning requirements are low, the conveying distance is set to be short; in addition, the conveying speed of the first tilting conveying unit 310, the second tilting conveying unit 320 and the third tilting conveying unit 330 can be adjusted to correspond to the rotation speed of the metal barrel A during the tilting cleaning mechanism 300, so as to change the grinding contact time between the abrasive grains and the metal barrel, and adapt to different grinding and cleaning requirements. Those skilled in the art can make adaptive adjustments according to actual production requirements, which are not specifically limited here.

[0043] In this embodiment, the first tilt conveying unit 310, the second tilt conveying unit 320 and the third tilt conveying unit 330 are two transmission belts arranged in parallel up and down, and the metal barrel A is driven by the two transmission belts to roll forward in the radial direction, and the two transmission belts are set at a differential speed to drive the metal barrel A to roll forward. Secondly, the conveying surfaces of the transmission belts at the first tilt conveying unit 310, the second tilt conveying unit 320 and the third tilt conveying unit 330 are correspondingly in a smoothly inclined transition structure.

[0044] Furthermore, some limiting structures such as guide limiting wheels (not shown in the figure) can be added on both sides of the two transmission belts in the same group to stop and limit the upper and lower ends of the metal, thereby preventing the metal barrel A from sliding and falling from the first tilting conveying unit 310, the second tilting conveying unit 320 and the third tilting conveying unit 330.

[0045] Furthermore, the barrel body grinding roller brush 130 and the end cover grinding roller brush 230 of the present embodiment are both provided with an adjusting mechanism for driving them to adjust their positions. The adjusting mechanism is specifically a telescopic cylinder acting on the end of the shaft, thereby driving the barrel body grinding roller brush 130 or the end cover grinding roller brush 230 to adjust their positions to a suitable position to adapt to metal barrels A of different specifications, thereby ensuring that the surface of the roller brush can abut against and grind the metal barrel A.

[0046] Furthermore, the above-mentioned barrel body grinding roller brush 130 and end cover grinding roller brush 230 can use different materials according to different grinding and cleaning requirements. For example, if it is necessary to remove stubborn layers such as paint on the outer surface, a wire brush material can be used; if polishing is required, a soft brush material can be used. There is no limitation here and it can be adaptively selected according to actual production needs.

[0047] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any technician familiar with the art who, without departing from the scope of the technical solution of the present invention, makes more possible changes and modifications to the technical solution of the present invention using the technical content disclosed above, or modifications are all equivalent embodiments of the present invention. Therefore, any equivalent and equivalent changes made according to the ideas of the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
