Description

Technical Field

[0001] The utility model belongs to the field of composite material production, and particularly relates to a cleaning drum for cleaning composite material products. Background Art

[0002] With the development of the times, the original materials can no longer meet the needs of current production and life. As a new type of material that combines the advantages of various materials, composite materials are being widely used. After the preparation of composite materials, it is necessary to clean their surfaces. At present, the existing drum cleaning technology has low cleaning efficiency when cleaning composite material products, and the cleaning quality is uneven and difficult to control, resulting in poor appearance quality of composite material products.

[0003] Chinese invention patent CN 110961401 A discloses an industrial cleaning machine for stainless steel plates, which includes a conveying roller line for conveying steel plates, and a flushing assembly for flushing the steel plates. It also includes a water tank with an open upper part and a water baffle covering the upper part of the water tank. Among them, the conveying roller line is horizontally arranged in the upper part of the water tank; the flushing assembly is arranged in the water baffle and the flushing direction is towards the roller line; a feeding port is opened in the lower part of the front side of the water baffle, and a discharging port is opened in the rear side of the water baffle; a vertically movable wiper blade is installed on the outer wall of the discharging port side through an adjusting assembly. Due to the use of a conveyor belt and a flushing method, its cleaning efficiency is low, the flushing can only wash one side and cannot deeply clean, resulting in poor cleaning ability, difficult to clean stubborn stains, and difficult to control the cleaning quality.

[0004] Chinese invention patent CN 109622490 A discloses a cleaning device for pump head valve springs, which includes a control box, a driving mechanism and several groups of cleaning components. The control box is electrically connected to the driving mechanism. The cleaning component includes a cleaning drum for storing springs and a water tank for storing cleaning liquid and placing the cleaning drum. A plurality of through holes are opened on the surface of the cleaning drum, and the cleaning drum is rotatably arranged in the water tank. The driving mechanism is connected to the cleaning drum to drive the cleaning drum to rotate. Since the pump head valve springs are very light in mass, small in volume, and the springs themselves are cylindrical, when the drum rotates at a high speed, it can cause a large impact between the springs and the liquid, fully clean the debris on the surface of the springs, strengthen the passivation effect of the springs, and improve the cleaning effect. However, when used to clean sheet composite materials, the high-speed rotating drum is easy to damage the composite materials. Moreover, when the drum rotates, the sheet composite materials are not easy to tumble and turn over, resulting in poor cleaning effect, and they will stick to each other to form patches, resulting in single-sided cleaning of the composite materials and inconsistent colors on both sides. In addition, due to the interaction between the drum and the liquid in the moving direction, bubbles are easily generated when the liquid enters and exits the openings of the cylinder body, affecting the cleaning effect.

[0005] The content in the background art section is only the technology known to the inventor and does not of course represent the prior art in this field. Summary of the Invention

[0006] In view of the above problems, in order to improve the cleaning effect, shorten the cleaning time, improve the cleaning efficiency, reduce the production cost and save resources, the present utility model provides a cleaning drum, comprising: a cylinder body, end panels disposed on both sides of the cylinder body, the end panels and the cylinder body enclosing an accommodation space for accommodating the product to be cleaned;

[0007] An openable device disposed on the drum for putting in and taking out the product to be cleaned;

[0008] Openings disposed on the drum for the cleaning liquid to flow in and out;

[0009] Partition strips are provided in the accommodation space, and the partition strips are connected to the inner wall of the cylinder body and the end panels at both ends. When the cylinder body rolls, the partition strips cause the product to be cleaned to flip and separate.

[0010] The composite material product rotates along the drum wall following the rotation of the drum. However, during the rotation process, it slides down according to gravity. At this time, due to the existence of partition strips on the drum, the product will be driven upward, and when it falls to a high point, because it is in the liquid, a certain buoyancy allows the product to slowly fall with the liquid, achieving flipping and turning over, and separating the composite materials that are stuck together. When the partition strips drive the composite material product, the thrust applied to it will also cause flipping and turning over, and separating the composite materials that are stuck together.

[0011] Further, the cylinder body is formed by sequentially connecting first side panels, and an opening is provided thereon; the drum cover is formed by sequentially connecting first side panels and is in conformity with the opening, and the drum cover is movably connected to the first side panels on both sides of the opening.

[0012] Further, the end panel comprises a main end panel and a sub-end panel; a first opening is provided on the main end panel; a second opening is provided on the sub-end panel; the aperture of the first opening is smaller than the aperture of the second opening; the sub-end panel and the main end panel are attached together to reinforce the main end panel and prevent it from deforming.

[0013] Small holes are opened on the main end panel to facilitate the entry and exit of the solution. Large holes are opened on the sub-end panel to reinforce the main end panel without affecting the entry and exit of the solution and prevent the drum from deforming.

[0014] During the rotation of the drum, due to the movement of the cylinder body, the side panel will interact with the liquid in the direction of the cylinder body movement, agitating the liquid. If the liquid only enters and exits through the side panel, it may cause air bubbles to form inside the cylinder, and the centrifugal force formed by the rotation of the cylinder body affects the liquid balance inside the cylinder. Since the end panel is perpendicular to the movement direction of the cylinder body, the liquid entering and exiting the cleaning drum through the end panel is less affected by the movement of the cylinder body, and the liquid is more free to enter and exit the cylinder, increasing the cleaning effect. Moreover, when the liquid enters and exits through the side panel, it will supplement the liquid affected by the centrifugal force formed by the rotation of the cylinder body inside the cylinder, keeping the liquid inside the cylinder full and stable, and ensuring the cleaning effect.

[0015] Further, the partition strip is perpendicularly connected to the first side panel, and the extending direction of the partition strip is parallel to the extending direction of the side panel towards the end panel and is connected to the end panel.

[0016] Further, the first openings are evenly distributed outward from the central area of the main board of the end panel. The total area of the first openings accounts for 50%-80% of the area of the main board of the end panel, the aperture is 1-5 mm, and the hole pitch between adjacent holes is 1-4 mm; among them, the first openings preferably have an aperture of 3 mm and the hole pitch between adjacent holes is 2 mm;

[0017] and / or, the size of the second openings is 5-10 times the size of the first openings;

[0018] and / or, the first side panel is provided with third openings, the aperture is 1-5 mm, and the hole pitch between adjacent holes is 1-4 mm; among them, the third openings preferably have an aperture of 3 mm and the hole pitch between adjacent holes is 2 mm.

[0019] The first openings are evenly distributed outward from the central area of the main board of the end panel, which can make the cleaning liquid enter the cleaning drum evenly. The total area of the first openings accounts for 50%-80% of the area of the main board of the end panel, which can ensure that the cleaning liquid enters the cleaning drum fully and quickly.

[0020] The aperture is 1-5 mm, the cleaning liquid can enter and exit freely, and the product to be cleaned will not leak out through the holes.

[0021] Further, the partition strip is 1-5 cm high and 1-3 mm thick; among them, it is preferably 3 cm high and 2 mm thick.

[0022] Further, the partition strips are provided on all the first side panels constituting the cylinder body and the drum cover plate, and the partition strips are located at the middle positions of the first side panels;

[0023] and / or, the cross-section of the cylinder body parallel to the end panel is an equilateral octagon, and the drum cover plate is preferably formed by connecting two of the first side panels.

[0024] A cylindrical body with an opening composed of six first side panels and a roller cover plate composed of two first side panels. The longitudinal section of the closed cylindrical body formed by the opening cylindrical body and the matching roller cover plate is an equilateral octagon, which is convenient for installation and rolling similar to a circle, reducing the accumulation of composite material products, thereby reducing the phenomenon of different colors of composite material product patches during the pickling process. For rollers with similar volumes, when the number of first side panels increases and the longitudinal section of the closed cylindrical body is a polygon with more than eight sides, the side length of the polygon will be shortened, the distance between adjacent partition bars will be reduced, and the activity space of the composite material products will be reduced.

[0025] The partition bars cause the composite material products to roll. When the partition bars are too high, it is easy to cause material stacking of the composite material products. When they are too low, the rolling effect is not ideal. If the partition bars do not extend to the end panels, there will be a certain space between them and the end panels, resulting in material jamming. Having 1 partition bar on each first side panel can maximize the rolling effect without causing material jamming.

[0026] The partition bars are vertically located in the middle of the first side panels, which can ensure uniform flipping of the composite material products and reduce the stacking of composite material products.

[0027] Furthermore, one end of the roller cover plate is connected to the first side panel on one side of the opening through a movable connection device, and a locking device is provided at the other end to lock the roller cover plate on the first side panel on the other side of the opening;

[0028] The movable connection device is preferably a hinge or a hinge.

[0029] Furthermore, the cleaning roller further includes a second side panel disposed within the opening and on the opposite side of the movable connection device, and two third side panels disposed on both sides of the second side panel and connected to the end panels. The third side panels and the second side panel are used to support and stabilize the roller cover plate.

[0030] Furthermore, the cleaning roller further includes an end panel welding part vertically disposed on the end panel and connected to the end panel. The end panel welding part is circular ring-shaped and has regular holes thereon, which are connected to the gear of the cleaning equipment; preferably, the connection method between the end panel welding part and the end panel is welding.

[0031] Due to the opening on the end panel, in order to increase the number of openings and reduce the area occupied in the middle position of the end panel, this application uses a circular ring-shaped end panel welding part welded to the end panel to drive the rotation of the roller. In addition, the opening on the end panel reduces the strength of the end panel. The connection area between the end panel welding part and the end panel is large, and the stress area of the end panel is large, making it not easy to be damaged during use.

[0032] The beneficial effects of the present utility model are:

[0033] By adding partition strips, it assists the composite material product to automatically turn over during cleaning, improves the rolling uniformity of the composite material product, reduces patch sticking, and also plays a role in stirring the cleaning liquid, enabling the composite material product to contact the cleaning liquid over a larger area and for a longer time, enhancing the cleaning effect, and reducing the phenomenon of different-colored patch sticking on the composite material product during pickling.

[0034] By drilling holes in the end panel, it promotes the flow of the cleaning liquid, increases the flow rate of the cleaning liquid, accelerates the drainage and the draining speed after cleaning ends, improves the cleaning efficiency, reduces the probability of watermarks generated in the composite material product, and lowers the production cost.

[0059] Refer to Figure 2 , in this embodiment, a partition strip 8 is arranged inside the barrel to facilitate the turning of the workpiece and does not affect the discharge of the workpiece; among them, the partition strip is vertically connected to the first side panel 2, the extending direction of the partition strip is parallel to the extending direction of the side panel towards the end panel, and it is connected to the end panel. The height of the partition strip is 1 - 5 cm and the thickness is 1 - 3 mm; among them, the preferred height is 3 cm and the preferred thickness is 2 mm.

[0060] Refer to Figure 1, in this embodiment, a number of regular holes 14 are provided in the end panel weldments 1 arranged in parallel on both sides of the cleaning drum, which facilitates the connection with the gears of the cleaning equipment and facilitates rotation. During use, the gears are connected to the end face plate weldments for rotation.

[0061] The following lists a specific method, and those skilled in the art can adopt other methods for replacement to meet the above structural functions. A cleaning drum is made of stainless steel. The cleaning drum includes two end panel weldments 1 arranged in parallel. The end panel weldments 1 are arranged vertically. The two end panel weldments 1 are respectively welded to the end panels and are located at the edges of the end panels. The end panel is composed of an end panel sub-board 11 and an end panel main-board 7 fitted together. The end panel main-board 7 is provided with first openings. As Figure 4 shown, the arrangement of the first openings is arranged horizontally in sequence, and vertically at uniform intervals, and is evenly distributed outward from the central area of the end panel main-board. The aperture is 4 mm, and the horizontal and vertical hole spacings are both 4 mm. The aperture of the holes in the end panel sub-board 11 is larger than that of the end panel main-board; a first side panel 2 is connected between the end panels. The first side panel 2 is arranged horizontally. The longitudinal section of the cleaning drum is an equilateral octagon. One side of the cleaning drum opening 12 is provided with a movable connection device 3 connected to the first side panel 2. Here, the movable connection device is selected as a hinge. The drum cover 9 is formed by connecting the two first side panels 2 end to end and is connected to the hinge 3. The drum cover 9 can rotate 90 degrees along the hinge 3. The locking device 5 is welded to the end of the drum cover 9 away from the hinge 3. Opening the drum cover 9 can put the workpieces to be barrel-plated into the drum. Closing the drum cover 9 and connecting the locking device 5 closes the cleaning drum. On the side opposite to the movable connection device 3 in the opening 12, there is a second side panel 4. Two third side panels 6 are located on both sides of the second side panel 4 and are connected to the end panels. The third side panels and the second side panel are used to support and stabilize the drum cover 9. There are 8 partition bars 8 arranged in the cleaning drum. The partition bars 8 are perpendicularly connected to the first side panel 2 at the middle position of the first side panel. The extending direction of the partition bars 8 is parallel to the extending direction of the side panel towards the end panel and is connected to the end panel. A number of regular holes 14 are provided in the end panel weldments 1, which facilitates the connection with the gears of the cleaning equipment and facilitates rotation. During use, a sheet-shaped composite material (with a length and width within 10*10 mm, a thickness within 2 mm, and an average weight of each sheet within 0.5 g - 0.1 g) is placed in the drum, and the drum cover is locked. The drum is placed on the hanging tool cart and pushed into the equipment. After the gears grab the drum, they drive the drum to rotate. The gears are located inside the end panel weldments of the drum and support the upper half of the end panel weldments of the drum. The rotation speed is 8 revolutions per minute, and the composite material is cleaned. In this application, a relatively slow rotation speed is adopted because most of the applied composite materials are sheet-shaped, and high-speed rotation is likely to cause damage to the composite materials. Moreover, the centrifugal force generated by the relatively slow rotation speed is smaller, and the impact on the liquid in the drum is also smaller.

[0062] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
