Description

Technical Field

[0001] The utility model belongs to the technical field of rock wool production equipment, and particularly relates to a brush roller structure and a cotton collecting machine for efficiently cleaning a screen plate with adjustable position. Background Technique

[0002] Rock wool is a kind of product mainly made of basalt, dolomite, etc. It is melted at a high temperature above 1450°C, centrifuged into fibers at high speed by a centrifuge, and at the same time, a certain amount of binder, dust-proof oil, and water-repellent agent are sprayed. Then it is collected by a cotton collecting machine, paved by a pendulum method process, and then solidified and cut to form rock wool products with different specifications and uses.

[0003] In the actual production process, the cotton collecting machine is an important link affecting product quality, and the permeability of the screen plate of the cotton collecting machine is of great significance to actual production. The main function of the screen plate of the cotton collecting machine is to adsorb the cotton filaments outside on the screen plate through the negative pressure air inside. A permeable screen plate can evenly adsorb the cotton filaments on the screen plate, and the quality of the primary felt formed is stable. If there is a problem of screen plate blockage, it will cause a decrease in cotton formation rate and uneven bulk density distribution of the primary felt, indirectly resulting in unstable bulk density of the final product. There are multiple reasons for screen plate blockage, mainly because the broken cotton is adsorbed in the mesh holes by negative pressure, and the lifting cotton air fails to completely blow out the broken cotton, resulting in a certain degree of blockage.

[0004] At present, the main cleaning method of the cotton collecting machine is to clean it through a brush roller.

[0005] However, due to the long length of the cotton collecting machine, and in order to maintain sufficient permeability of the screen plate, a larger mesh area is required, so there are relatively weak positions in the strength of the screen plate of the cotton collecting machine. The screen plate often shows slight deformation. In this case, it is very difficult for the brush roller of the cotton collecting machine to clean the screen plate of the cotton collecting machine comprehensively. For example, there is a situation where the middle part of some screen plates of the cotton collecting machine is sunken. Since the length of the brush roller is the same as the length of the cotton collecting machine, under the action of pressure, the brush roller will press on both sides of the cotton collecting machine and carry out cleaning work, but the middle part cannot be cleaned in time due to insufficient pressure. In addition, all the screen plates of the cotton collecting machine do not have the same deformation situation, so this problem cannot be solved by using a special brush roller length. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the utility model provides a brush roller structure and a cotton collecting machine for efficiently cleaning a screen plate with adjustable position, and solves the problem of cleaning the deformed cotton collecting screen plate. The technical solution of the utility model is as follows:

[0007] On the one hand, the utility model provides a brush roller structure for efficiently cleaning a screen plate with adjustable position, including a brush roller frame body, and a brush roller, a support shaft, a connecting piece, and a counterweight block arranged on the brush roller frame body;

[0008] The brush roll and the counterweight are respectively arranged at two ends of the connecting member, and the connecting member is swingably arranged on the brush roll frame through a support shaft;

[0009] It further includes a power motor for driving the brush roll to rotate. The power motor is arranged on the connecting member and is connected to the brush roll through a transmission belt.

[0010] Preferably, the brush roll and the counterweight are respectively connected to the connecting member through their respective central axes, forming a frame structure with the connecting member.

[0011] Preferably, the counterweight is cylindrical, with a through hole provided in the center, and is connected to the connecting member through a central axis.

[0012] Preferably, the support shaft is a smooth shaft, allowing the connecting member to slide horizontally along the axial direction of the support shaft, and at the same time ensuring that the connecting member swings around the support shaft.

[0013] It further includes a moving motor arranged on the brush roll frame, and a translation belt. Two ends of the translation belt are respectively connected to the connecting member, and by the forward and reverse rotation of the moving motor, the connecting member together with the brush roll is driven to adjust the horizontal position.

[0014] In this embodiment, the connecting member is a connecting rod.

[0015] Specifically, the translation belt bypasses the moving motor and the pulley fixed on the brush roll frame, and the two ends are respectively tied to both sides of the connecting member.

[0016] The length of the brush roll is about 1 / 4 of the length of the entire cotton collecting machine wire mesh. The shorter length is easy to replace the bristles, and due to the smaller contact area, the fitting degree for the slight deformation of the wire mesh is better.

[0017] The structure of the brush roll includes an intermediate roller, a bristle fixing seat fixed on the intermediate roller, and bristles. The bristle fixing seat and the bristles are both made of nylon material and have a certain elasticity, playing a buffering role under the action of the bristles and the counterweight at the uneven positions of the wire mesh.

[0018] As the second aspect of the present utility model, it lies in providing a cotton collecting machine, which is a drum - type cotton collecting machine.

[0019] Preferably, the brush roll for efficiently cleaning the wire mesh with adjustable position is arranged below the cotton lifting air outlet of the cotton collecting machine, and the rotation direction of the brush roll is the same as the rotation direction of the cotton collecting wire mesh of the cotton collecting machine. In this way, the linear velocity direction of the contact surface is the relative movement direction, strengthening the friction effect.

[0020] Preferably, the brush roll frame is connected to the overall structure of the cotton collecting machine and is fixed on the centrifugal machine frames on both sides.

[0021] Compared with the prior art, the excellent effects that can be achieved include:

[0022] 1. Due to the presence of counterweights, the brush roller can better conform to the screen plate of the cotton collecting machine. By appropriately adjusting the counterweights, a good balance can be achieved between the wear of the brush bristles of the brush roller and the cleaning effect.

[0023] 2. Since the length of the brush roller is shorter, it can better conform to the change in the height of the screen plate of the cotton collecting machine (i.e., better cope with the deformation of the screen plate of the cotton collecting machine). Especially for large production lines with a relatively long screen plate of the cotton collecting machine, it is difficult for the same screen plate to remain absolutely straight. When slight deformation occurs due to pressure or external factors, the through-axis brush roller cannot brush to positions that are relatively far away (relatively concave positions). For the same position, the heights of different screen plates are also inconsistent. Prolonged use of the through-axis brush roller will cause different positions to not be effectively cleaned. The present utility model provides a shorter brush roller, which has a smaller contact area with the screen plate of the cotton collecting machine. From the perspective of the length direction of the screen plate, the contact amount is smaller.

[0024] 3. This device can achieve efficient cleaning of the screen plate of the cotton collecting machine and solve the cleaning problem of the deformed cotton collecting screen plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Embodiment 1. A brush roller structure for efficiently cleaning a screen plate with adjustable position

[0032] As Figure 1 shown, it includes a brush roller 1, a support shaft 2, a connecting rod 3, a counterweight 4, a power motor 5, a moving motor 6, and a translation belt 7. The brush roller 1 and the counterweight 4 are respectively arranged at both ends of the connecting rod 3. The connecting rod 3 is arranged on a brush roller frame 8 through the support shaft 2. The support shaft 2 is a smooth shaft, allowing the connecting rod 3 to slide horizontally along the axial direction of the support shaft 2, and at the same time, it can ensure that the connecting rod 3 swings around the support shaft 2; the rotation direction of the brush roller is clockwise rotation. The connecting rod 3 is used to connect the brush roller 1 and the counterweight 4. As a typical embodiment, the cylindrical counterweight 4 is connected to the connecting rod 3 in the form of a through hole at the center. The cylindrical counterweight avoids the fluctuations caused by unstable center of gravity, so that the counterweight pressure remains consistent at any time. The connecting rod 3 is connected to the support shaft 2 through a support bearing sleeved on the support shaft 2. Under the action of the gravity of the counterweight 4, the brush roller 1 is pressed on the screen plate of the cotton collecting machine. The brush roller is connected to the output shaft of the power motor. The power motor 5 is fixed on the connecting rod 3, and the output shaft of the power motor 5 drives the brush roller to rotate through a transmission belt. The moving motor 6 is fixed on the brush roller frame 8 and is connected to the translation belt 7 through a pulley.

[0033] As Figure 2 shown, the connecting rod 3 is composed of two pieces located on the left and right sides of the brush roller, and forms a frame structure with the central axis of the brush roller and the central axis of the counterweight. The two ends of the translation belt 7 are respectively connected to the left and right connecting rods 3. By the forward and reverse rotation of the moving motor 6, the horizontal position adjustment of the entire brush roller is completed. Specifically, the translation belt 7 bypasses the moving motor 6 and the pulley fixed on the brush roller frame 7, and the two ends are respectively tied to both sides of the connecting rod. The moving motor 6 drives the brush roller to reciprocate horizontally along the support shaft through the translation belt 7, realizing the cleaning of the screen plate in the horizontal direction. It can be seen from the attached drawing that the length of the brush roller is about 1 / 4 of the length of the entire screen plate of the cotton collecting machine. The shorter length is easy to replace the bristles, and due to the smaller contact area, the fitting degree for the slight deformation of the screen plate is better. The present utility model can, under the support of the support shaft 2, the brush roller and the counterweight can move along the support shaft to achieve the cleaning work of the entire screen plate.

[0034] The structure of the brush roll includes an intermediate roller, a brush fixing seat fixed on the intermediate roller, and brushes. The brush fixing seat and the brushes are both made of nylon and have a certain elasticity. At the uneven positions of the mesh plate, they play a buffering role under the action of the brushes and the counterweight.

[0035] Embodiment 2, a cotton collecting machine

[0036] As Figure 1 shown, it is a drum-type cotton collecting machine with a clockwise rotation direction. The brush roll structure for efficiently cleaning the mesh plate with adjustable position provided in Embodiment 1 is arranged below the cotton lifting air inlet of the cotton collecting machine. The rotation direction of the brush roll should be the same as that of the cotton collecting machine, so that the linear velocity direction of the contact surface is the relative motion, strengthening the friction effect. The brush roll frame 8 is connected to the overall structure of the cotton collecting machine. Specifically, it can be fixed on the centrifugal frames on both sides.

[0037] The present utility model provides a brush roll that can slide left and right for cleaning the mesh plate. The brush roll is in direct contact with the mesh plate of the cotton collecting machine, and the mesh plate of the cotton collecting machine is cleaned by the rotation of the brush roll to brush off the broken cotton on the mesh plate, so as to achieve the effect of cleaning the mesh plate.

[0038] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
