Description

Technical Field

[0001] The invention relates to a cleaning device for a can-making conveying line, belonging to the technical field of cleaning equipment. Background Art

[0002] In the production of cans, the conveyor belt needs to continuously and stably transport a large number of cans to various processing links, such as stretching, curling, drying, etc. However, during this process, the surface of the conveyor belt is very easy to become dirty due to the accumulation of stubborn attachments such as aluminum chips, which not only affects the cleanliness of the production environment, but also may pollute the surface quality of the cans, thereby affecting the appearance and quality of the product; traditional conveyor belt cleaning methods mostly use vertically arranged brush rollers or simple scrapers. These methods are often difficult to achieve ideal cleaning effects when facing small and highly adhesive dirt such as aluminum chips. The vertical contact method limits the effective contact area and scraping force between the brush wire and the conveyor belt surface, resulting in incomplete cleaning and prone to cleaning blind spots. Therefore, a canning conveyor line cleaning device is proposed. Summary of the invention

[0003] The object of the present invention is to provide a canning conveyor line cleaning device to solve the problems raised in the above-mentioned background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a canning conveyor line cleaning device, comprising:

[0005] Two mounting brackets, the two mounting brackets are symmetrically installed under the conveyor belt support;

[0006] The drum is installed between the two mounting frames, and the two ends of the drum are rotatably connected to the two mounting frames respectively;

[0007] Multiple rows of brush wires are circumferentially distributed on the drum;

[0008] When the drum rotates, the brush wires rotating to the upper part of the drum come into contact with the lower surface of the conveyor belt;

[0009] A plurality of adjusting rods, wherein the plurality of adjusting rods are evenly distributed along the circumference of the drum, each adjusting rod is parallel to the axis of the drum, and adjacent adjusting rods can move at the same speed and in opposite directions along the axis of the drum;

[0010] Multiple levers, multiple levers are evenly distributed on the adjustment rod, and each lever is horizontally placed against one side of the corresponding brush wire;

[0011] When the adjusting rod moves, the brush wires are tilted to one side by the shifting post, and the tilting directions of the brush wires in two adjacent rows are opposite.

[0012] Preferably, connecting columns are fixed at both ends of the drum, and the two connecting columns are rotatably connected to the mounting frames on the same side.

[0013] Preferably, both connecting columns are provided with:

[0014] A sliding block, wherein the sliding block can slide along the axis of the drum;

[0015] A plurality of support rods, wherein the plurality of support rods are circumferentially fixed on the sliding block, and each support rod penetrates the side wall of the connecting column and extends to the outside;

[0016] A plurality of guide sleeves are circumferentially fixed on the outer wall of the connecting column, and the plurality of guide sleeves of one connecting column correspond one to one with the plurality of support rods on another connecting column;

[0017] One end of the adjusting rod is fixedly connected to the supporting rod, and the other end of the adjusting rod is slidably sleeved inside the corresponding guide sleeve.

[0018] Preferably, an inner rod is axially arranged inside the roller and the two connecting columns, and two sliding blocks are sleeved on the inner rod through threaded engagement, and the engagement threads of the two sliding blocks and the inner rod are opposite, and one end of the inner rod extends to the outside and is provided with a hexagonal countersunk hole.

[0019] Preferably, a bearing is provided at the connection between the connecting column and the mounting frame.

[0020] Preferably, there is an included angle α between the lever column and the adjusting rod, and the included angle α is an acute angle.

[0021] Preferably, a plurality of limiting grooves for preventing the brush filaments from moving on the pin are evenly formed on the side wall of the pin.

[0022] Preferably, one end of the lever away from the adjusting rod is bent, and the bending direction of the end of the lever is toward the direction in which the lever drives the brush filaments to tilt.

[0023] Preferably, a plurality of fixing grooves are distributed circumferentially on the outer wall of the drum, and a bottom rod for connecting the brush filaments is fixed inside each fixing groove.

[0024] Compared with existing technologies:

[0025] The drum of the present invention rotates with the brush wires, and the inclined brush wires contact the surface of the conveyor belt. This non-vertical contact mode increases the scraping and friction of the brush wires on the surface of the conveyor belt. The increased friction helps to remove the stubborn attachments on the surface of the conveyor belt more deeply. At the same time, the inclined brush wires also produce an inclined linear "shoveling" effect, which is similar to using a shovel to shovel dirt on the ground, which helps to peel off and remove stubborn dirt from the surface of the conveyor belt, significantly enhancing the cleaning effect.

[0026] The present invention provides an acute angle between the lever and the adjusting rod, so that when the adjusting rod moves, it can gradually and gradedly push the brush wire to tilt, which not only enhances the cross density between adjacent brush wires, but also ensures that the brush wire can more comprehensively cover the conveyor belt surface during the rotation of the drum, reducing the cleaning blind area. At the same time, the ingenious setting of the limit groove effectively prevents the brush wire from moving on the lever, ensuring the stability and consistency of the brush wire tilt angle, thereby improving the uniformity and depth of cleaning.

[0046] The present invention is described below with specific embodiments, but they are not intended to be limiting of the invention.

[0047] Embodiment 1

[0048] like Figure 1-Figure 8 As shown, in this embodiment, a can-making conveyor line cleaning device is provided, including two mounting frames 1, the two mounting frames 1 are symmetrically installed under the conveyor belt support, a roller 2 is installed between the two mounting frames 1, and the two ends of the roller 2 are rotatably connected to the two mounting frames 1 respectively; multiple rows of brush wires 3 are distributed circumferentially on the roller 2; when the roller 2 rotates, the brush wires 3 rotated to the upper part of the roller 2 contact the lower surface of the conveyor belt; multiple adjusting rods 4 are evenly distributed circumferentially on the roller 2, each adjusting rod 4 is parallel to the axis of the roller 2, and adjacent adjusting rods 4 can be displaced at the same speed and in opposite directions along the axis of the roller 2; multiple shifting posts 5 are evenly distributed on the adjusting rod 4, each shifting post 5 is horizontally placed against one side of the corresponding brush wire 3; when the adjusting rod 4 moves, the shifting post 5 shifts the brush wire 3 to one side, and the inclination directions of the two adjacent rows of brush wires 3 are opposite.

[0049] Brush wires 3 are distributed and contact with the base: First, multiple rows of brush wires 3 are distributed circumferentially on the roller 2. When the roller 2 rotates synchronously or asynchronously with the conveyor line (using an external motor to drive the roller 2 to rotate, and the external motor can be fixed on the conveyor belt bracket), these brush wires 3 will pass through the lower surface of the conveyor belt in turn. Since the brush wires 3 are in direct contact with the conveyor belt, they can initially scrape or brush the attachments on the surface of the conveyor belt (such as attached aluminum powder).

[0050] Functions of the adjusting rod 4 and the lever 5: In order to enhance the cleaning effect, the adjusting rod 4 and the lever 5 are introduced. Multiple adjusting rods 4 are evenly distributed along the circumference of the drum, and adjacent adjusting rods 4 can move along the axis of the drum 2 at the same speed but in opposite directions. When each pair of adjacent adjusting rods 4 (and the lever 5 thereon) moves, they push the corresponding brush filaments 3 to both sides of the drum 2, causing the brush filaments 3 to tilt.

[0051] The brush wire 3 is tilted and the angle is generated: when the lever 5 moves with the adjusting rod 4, they will resist and push one side of the brush wire 3, causing the brush wire 3 to tilt to one side. Figure 5 As shown, since the adjacent adjustment rods 4 move in opposite directions, the two adjacent rows of brush wires 3 will be inclined to the two sides of the drum 2 to form a cross, as shown in FIG. Figure 5 The horizontal dotted line a shown in the figure is the outermost cross position of the brush filaments 3, and the part of the brush filaments 3 in contact with the conveyor belt surface is at least a part located above the dotted line a. This design of inclination and angle ensures that when each row of brush filaments 3 rotates to contact the conveyor belt, it not only has a force in the vertical direction, but also generates a component in the horizontal direction (i.e., the moving direction of the conveyor belt).

[0052] Strengthening of the cleaning process: When the inclined brush wire 3 contacts the conveyor belt surface, due to the angle between the brush wire 3 and the conveyor belt movement direction, this non-perpendicular contact mode increases the scraping and friction of the brush wire 3 on the conveyor belt surface. The increased friction helps to remove the stubborn attachments on the conveyor belt surface more deeply. At the same time, the inclined brush wire 3 also produces an inclined linear "shoveling" effect, which is similar to using a shovel to remove dirt on the ground, helping to peel off and remove stubborn dirt from the conveyor belt surface.

[0053] Comprehensive effect: Through the above mechanism, not only the basic cleaning of the conveyor belt surface is achieved, but also the cleaning effect is significantly enhanced through the inclination and angle design of the brush wire 3.

[0054] The two ends of the drum 2 are fixed with connecting columns 6, and the two connecting columns 6 are rotatably connected to the mounting frame 1 on the same side through bearings 11. The two ends of the drum 2 are rotatably connected to the mounting frame 1 through the connecting columns 6, so that the drum 2 can rotate freely around its axis. Figure 6 As shown, both ends of the drum 2 are provided with plug-in parts, and the plug-in parts of the drum 2 can be plugged into the inside of the connecting column 6, and then the connecting parts are fixed in the connecting column 6 by bolts, so as to achieve the fixation of the drum 2 and the connecting column 6.

[0055] One end of the lever 5 away from the adjusting rod 4 is bent, and the bending direction of the end of the lever 5 is toward the direction in which the lever 5 pushes the brush filaments 3 to tilt, which can prevent the brush filaments 3 from escaping from the lever 5.

[0056] The outer wall of the drum 2 is circumferentially distributed with a plurality of fixed grooves 201 , and a bottom rod 12 for connecting the brush filaments 3 is fixed inside each fixed groove 201 . The brush filaments 3 on one bottom rod 12 are regarded as a row. When the bottom rod 12 is fixed in the fixed groove 201 , the brush filaments 3 can be quickly installed on the drum 2 .

[0057] Embodiment 2

[0058] like Figure 6 and Figure 7 As shown, based on the first embodiment, in order to drive the adjacent adjusting rods 4 to move synchronously in opposite directions, the two connecting columns 6 are provided with sliding blocks 7, which can slide along the axis of the drum 2; a plurality of supporting rods 8 are fixed circumferentially on the sliding blocks 7, each supporting rod 8 penetrates the side wall of the connecting column 6 and extends to the outside, as shown in FIG. Figure 6 As shown, a through groove 601 is provided on the side wall of the connecting column 6 for the support rod 8 to pass through, and the through groove 601 has a certain length, which can meet the sliding requirements of the support rod 8 on the connecting column 6 along with the sliding block 7; a plurality of guide sleeves 9 are fixed circumferentially on the outer wall of the connecting column 6, and a guide hole parallel to the axial direction of the roller 2 is provided inside each guide sleeve 9, and the plurality of guide sleeves 9 of one connecting column 6 correspond one-to-one to the plurality of support rods 8 on another connecting column 6; one end of the adjusting rod 4 is fixedly connected to the support rod 8, and the other end of the adjusting rod 4 is slidably sleeved in the guide hole of the corresponding guide sleeve 9.

[0059] Each connecting column 6 is provided with a sliding block 7 , a supporting rod 8 , and a sliding guide sleeve 9 , and these components together constitute a driving and guiding mechanism of the adjusting rod 4 .

[0060] Functions of the sliding block 7 and the support rod 8:

[0061] The sliding block 7 can slide inside the connecting column 6 along the axis of the drum 2. Since the two sliding blocks 7 are respectively located at the two ends of the drum 2, their synchronous reverse movement will move the linkage adjustment rod 4.

[0062] The support rods 8 are circumferentially fixed on the sliding block 7 and extend to the outside through the side walls of the connecting column 6. These support rods 8 are the fixing points of the adjusting rod 4, and the movement of the adjusting rod 4 is driven by their movement.

[0063] Cooperation between the guide sleeve 9 and the adjusting rod 4:

[0064] The guide sleeve 9 is fixed on the outer wall of the connecting column 6 in the circumferential direction, and corresponds to the support rod 8 on the heterodox connecting column 6. These guide sleeves 9 provide a sliding track for one end of the adjusting rod 4 to ensure the stability of the adjusting rod 4 during movement.

[0065] One end of the adjusting rod 4 is fixedly connected to the support rod 8 , and the other end is slidably sleeved inside the corresponding guide sleeve 9 , so that the adjusting rod 4 can move smoothly in a straight line under the guidance of the guide sleeve 9 .

[0066] An inner rod 10 is axially arranged inside the drum 2 and the two connecting columns 6. The two ends of the inner rod 10 are rotatably connected to the two connecting columns 6 respectively. The two sliding blocks 7 are sleeved on the inner rod 10 through threaded engagement, and the engagement threads of the two sliding blocks 7 and the inner rod 10 are opposite. One end of the inner rod 10 extends to the outside and is provided with a hexagonal countersunk hole for cooperating with an external tool to drive the inner rod 10 to rotate. When the inner rod 10 rotates, the two sliding blocks 7 move in opposite directions at the same speed.

[0067] Function and drive of inner rod 10:

[0068] The inner rod 10 is axially arranged inside the drum 2 and the two connecting posts 6, and is rotatably connected to the two connecting posts 6. In this way, the inner rod 10 can drive the movement of the two sliding blocks 7 by rotating.

[0069] The two sliding blocks 7 are sleeved on the inner rod 10 through threaded engagement, and their engagement threads are in opposite directions. When the inner rod 10 rotates, the two sliding blocks 7 can move at the same speed but in opposite directions.

[0070] One end of the inner rod 10 extends to the outside and is provided with a hexagonal countersunk hole so that an external tool (such as a hexagonal wrench) can be used to rotate the inner rod 10. In this way, the operator can conveniently control the rotation of the inner rod 10 and adjust the inclination angle of the brush filament 3.

[0071] In addition, a locking bolt is provided between the inner rod 10 and any one of the connecting columns 6. After adjusting the inclination angle of the brush wire 3, the inner rod 10 is locked by the locking bolt, so that the inner rod 10 can rotate synchronously with the connecting column 6 and the drum 2. The locking bolt is a prior art structure, so it will not be described in detail.

[0072] Embodiment 3

[0073] like Figure 9-11 As shown, based on the above embodiment, in order to further improve the cleaning efficiency, the present embodiment has an angle α between the lever 5 and the adjusting rod 4, and the angle α is an acute angle; Fig. 9 As shown, when the adjusting rod 4 moves along the arrow L, the brush filaments 3 close to the adjusting rod 4 first contact the lever 5, and the brush filaments 3 farther away from the adjusting rod 4 contact the lever 5 later. In this way, after the adjusting rod 4 moves a certain distance, the brush filaments 3 closer to the adjusting rod 4 are moved by the lever 5 at a greater angle, forming a fan-shaped structure, resulting in a greater cross density of the brush filaments 3 in two adjacent rows (such as Fig.10 and Fig.11 As shown in FIG. 1 ), this structure can more completely cover the surface of the conveyor belt during the rotation process, thereby improving the uniformity and depth of cleaning. A plurality of limiting grooves 501 are evenly provided on the side wall of the lever 5 to prevent the brush filaments 3 from moving on the lever 5.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
