[0024] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0025] This application provides a multi-directional limiting bearing seat for a carding machine, comprising: a main support part 1, which is block-shaped and used to connect to the carding machine frame and support the rotating parts of the carding machine; a groove 2 is provided on the top of the main support part 1; a bearing mounting hole 11, which penetrates the main support part 1 along a first direction and is used to install a rolling bearing; a first limiting hole 12, which penetrates the main support part 1 along the first direction; and a second limiting hole 13, which penetrates the main support part 1 along a second direction and communicates with the first limiting hole 12, wherein the first direction is perpendicular to the second direction; the first limiting hole 12 and the second limiting hole 13 are used to install a positioning pin. The shaft can prevent the bearing housing from rotating circumferentially; the bottom of the groove 2 is provided with a grease nipple hole 3, which is connected to the bearing mounting hole 11. The grease nipple hole 3 can deliver grease to the bearing in the bearing mounting hole 11 through the grease nipple hole 3; along the second direction, the main support part 1 includes a first side 1a and a second side 1b. The first side 1a is provided with a positioning step, which is used to cooperate with the step groove of the carding machine frame for positioning; the bottom of the main support part 1 is provided with two sets of limiting bosses 4, which are located on the side where the second side 1b is located and are arranged opposite to each other along the first direction. The limiting bosses 4 are used to limit the axial displacement of the bearing housing.

[0026] With reference to the drawings, the bearing housing is shown in the embodiment. Figures 1 to 5 The bearing housing comprises a main support part 1 in block structure, which is provided with an embedding groove 2 at the top and two sets of limiting bosses 4 at the bottom.

[0027] The embedding groove 2 is open, which can be used as an installation interface of external components, such as protective covers, transmission components or other auxiliary devices. For example, the belt cover or sensor assembly of the carding machine can be quickly positioned and fixed through the embedding groove 2, forming an integrated installation interface.

[0028] The embedding groove 2 is provided with a grease nozzle hole 3 at the bottom, which extends longitudinally and communicates with the bearing mounting hole 11. By installing a grease nozzle (such as a butter nozzle) in the embedding groove 2, lubricating grease can be injected into the rolling bearing mounted in the bearing mounting hole 11 through the grease gun, so that lubrication maintenance can be completed without disassembling the components, improving the convenience of maintenance.

[0029] In the second direction, the embedding groove 2 is provided with two downwardly tapered inclined sliding surfaces 2a on both sides of the top opening.

[0030] With reference to the drawings, the embedding groove 2 is provided with two downwardly tapered inclined sliding surfaces 2a on both sides of the top opening. Figure 2 The inclined sliding surfaces 2a can guide the external components such as protective covers and transmission components to be embedded in the embedding groove 2, achieving quick centering. At the same time, the contact surface between the inclined sliding surface 2a and the external component forms an inclined surface constraint. When the external component is embedded in the embedding groove 2, the normal component of the inclined sliding surface 2a can press the external component towards the center of the embedding groove 2, limiting its radial horizontal shaking, thereby improving the stability of the installation.

[0031] Optionally, the two sets of inclined sliding surfaces 2a are symmetrically distributed, and the inclination angle of the inclined sliding surface 2a is 15°-45°.

[0032] The inclination angle of the inclined sliding surface 2a is preferably 30°.

[0033] The embedding groove 2 is provided with a grease nozzle hole 3 at the bottom, which is used to inject lubricating grease into the bearing mounting hole 11. The inclined angle of the inclined sliding surface 2a can guide the accidental overflow of lubricating grease to flow back along the inclined surface to the embedding groove 2, avoiding the accumulation of oil on the top of the bearing housing, thereby reducing the risk of pollution. The flow guiding effect of the inclined sliding surface can keep the surface of the bearing housing clean, meeting the hygiene requirements of the carding machine for dust and oil pollution prevention.

[0034]

[0035] Figure 1 ​In the embodiment, the second direction is the left-right direction, the right side of the body support part 1 is the first side la, and the left side is the second side lb. The first direction is the vertical direction, the front of the body support part 1 is the third side lc, and the back is the fourth side.

[0036] One end of the slot 2 penetrates the third side lc of the body support part 1, forming a through structure. This design allows the grease nipple to be exposed from the side, making it easy for the operator to perform the grease injection operation without touching the rotating parts. In other embodiments, the operator can directly contact the inside of the slot 2 from the side without disassembling other parts to complete the installation, debugging, or disassembly of external devices such as protective covers and sensors; it can also reserve installation space for wires, pipelines, etc., avoiding structural interference.

[0037] Continuing to refer to Figure 1 , there is a thickness difference between the upper and lower parts of the first side la, forming a positioning step. During installation, the bearing seat is matched with the step groove of the carding machine frame through the positioning step.

[0038] Continuing to refer to Figure 1 , the bearing mounting hole 11 and the first limiting hole 12 both penetrate the body support part 1 along the first direction. The second limiting hole 13 penetrates the body support part 1 along the second direction. The first limiting hole 12 and the second limiting hole 13 are connected to form a cross-shaped limiting channel, which can be inserted into the positioning pin shaft.

[0039] During installation, the positioning pin shaft is vertically intersected by the first limiting hole 12 and the second limiting hole 13, which can limit the circumferential rotation of the bearing seat around the shaft. Compared with the traditional single bolt fixation, the multi-directional positioning pin shaft can significantly improve the circumferential anti-rotation accuracy and avoid installation looseness caused by vibration.

[0040] In combination with reference to Figure 3 and Figure 4 , the first limiting hole 12 is connected to the second limiting hole 13. The connected hole provides multi-surface contact support for the positioning pin shaft. After the two sets of positioning pin shafts are inserted into the first limiting hole 12 and the second limiting hole 13, a contact surface is formed through the connected hole, thereby reducing the risk of pin shaft bending or loosening caused by single-point stress.

[0041] The connection design of the two sets of limiting holes can disperse the load and improve the anti-vibration capability. During the operation of the carding machine, high-frequency vibration can cause fatigue deformation of the traditional single-point limiting pin shaft, while the multi-directional support of the connected hole can evenly distribute the vibration stress to the four walls of the hole, thereby prolonging the service life of the positioning pin shaft.

[0042] Optionally, the multi-directional limiting bearing seat for a carding machine provided by the present application further comprises a fixed pin hole 23, which is arranged on the third side lc and is connected to the second limiting hole 13; the fixed pin hole 23 is used for fastening the positioning pin shaft inserted into the second limiting hole 13 through a fixed pin.

[0043] Specifically refer to Figure 1 , Figure 2 and Figure 5 , when the first limiting hole 12 and the second limiting hole 13 are inserted with the positioning pin shaft, the fixed pin hole 23 is inserted with the fixed pin, and the fixed pin is used for further locking the pin shaft.

[0044] The double locking mechanism can ensure the reliability of the anti-rotation. The fixed pin hole 23 provides an insertion path for the fixed pin, so that the positioning pin shaft is fixed in the circumferential direction and the axial direction, avoiding the positioning pin shaft from being shaken out or loosened in long-term operation.

[0045] Optionally, the bearing mounting hole 11 is provided with an annular clamping groove 14, and the annular clamping groove 14 is used for mounting a sealing element.

[0046] Optionally, the bearing mounting hole 11 is provided in a two-section structure, including a first section and a second section, the hole diameter of the first section is smaller than that of the second section, and the first section and the second section have a step for limiting the axial position of the rolling bearing.

[0047] Specifically refer to Figure 4 , in the illustrated embodiment, the first section is arranged on the left, and the second section is continuous with the first section and arranged on the right. The hole diameter of the second section is larger, so as to facilitate the installation of the rolling bearing. The step is used as an axial shoulder for limiting the rolling bearing.

[0048] Continue to refer to Figure 4 , the second section is provided with a ring of annular clamping grooves 14 for embedding a sealing ring or a dust cover. The rolling bearing outer ring is mounted in the second section, and the inner ring is matched with the shaft. The step is used for abutting against the end face of the rolling bearing outer ring, and can limit the axial displacement of the rolling bearing. The sealing element in the annular clamping groove 14 can prevent the leakage of lubricating grease outward and prevent dust from entering, so as to prolong the service life of the bearing and adapt to the high-dust environment of the carding machine.

[0049] Optionally, the multi-directional limiting bearing seat for the carding machine provided by the present application further comprises: a first screw hole 21 arranged on the upper part of the third side face 1c and adjacent to the first side face 1a; and a second screw hole 22 arranged on the lower part of the third side face 1c and adjacent to the second side face 1b; the first screw hole 21 and the second screw hole 22 are used for fixing the bearing seat and the carding machine rack through bolts.

[0050] Specifically refer to Figure 1 and Figure 2 , in the illustrated embodiment, the first screw hole 21 is arranged on the upper left side of the front of the main body support part 1, and the second screw hole 22 is arranged on the lower right side. During installation, the screw holes on the main body support part 1 are aligned with the mounting holes (which can be screw holes or ordinary through holes) on the mounting surface of the carding machine rack, and the bolts are inserted, so that the main body support part 1 and the rack can be fixed through the bolts.

[0051] With reference to the foregoing Figure 1 And Figure 2 The front surface of the body support part 1 is further provided with a fixing pin hole 23, which is arranged below the second screw hole 22. The fixing pin hole 23 is communicated with the second limiting hole 13, and a fixing pin can be inserted to lock the positioning pin shaft.

[0052] Specifically, the first screw hole 21 and the second screw hole 22 oppositely arranged on the top and bottom surfaces are matched with the positioning step to form a three-point fixing, and combined with the secondary locking of the positioning pin shaft by the fixing pin, the multi-directional mechanical constraint can be achieved. Compared with the traditional single-point bolt fixing, the multi-branch point structure can uniformly disperse the load, improve the anti-overturning ability, and ensure the positioning accuracy during long-term operation.

[0053] Optionally, the surface of the body support part 1 for connecting the carding machine frame is provided with a shock-absorbing buffer layer for reducing the vibration transmission during the operation of the carding machine.

[0054] The surface of the bottom of the body support part 1 for connecting the frame is provided with a shock-absorbing buffer layer, which can be made of elastic materials such as rubber or polytetrafluoroethylene. The shock-absorbing buffer layer can absorb the energy generated by the vibration of the carding machine through elastic deformation, thereby improving the stability and reliability of the connection and installation of various components.

[0055] Optionally, the thickness of the shock-absorbing buffer layer is 0.5-2mm, and the specific value needs to be adjusted in combination with the vibration intensity of the carding machine.

[0056] For example, in a light load scenario (such as a doffer shaft), the thickness of the shock-absorbing buffer layer is 0.5-1mm, which can balance the shock absorption and installation accuracy.

[0057] For example, in a heavy load scenario (such as a cylinder shaft), the thickness of the shock-absorbing buffer layer is 1-2mm, which can enhance the buffering effect and reduce the vibration transmission to the frame.

[0058] The shock-absorbing buffer layer can absorb vibration energy through elastic deformation of the material, reduce the rigid impact between the bearing seat and the frame, and at the same time suppress resonance through damping effect, thereby reducing the bearing operation noise.

[0059] In a specific embodiment, the multi-directional limiting bearing seat is used to support the licker-in shaft, the cylinder shaft or the doffer shaft of the carding machine, and is fixedly connected with the mounting surface of the carding machine frame through the positioning step, the limiting boss 4 and the bolt.

[0060] For example Figures 1 to 5As shown, the bearing seat is matched with the horizontal / vertical surface of the step groove of the carding machine frame through the positioning step, the limiting boss 4 is abutted with the limiting surface of the frame, and the combination of the first screw hole 21, the second screw hole 22 and the positioning pin shaft realizes the multidirectional fixation of the components such as the licker-in shaft and the cylinder shaft. Among them, the positioning step can limit the horizontal displacement, the limiting boss 4 can limit the axial movement, and the positioning pin shaft can limit the circumferential rotation, finally forming a reliable three-dimensional space constraint, improving the shafting centering, reducing the noise (≤65dB) and energy loss caused by the movement, and ensuring the use stability and motion accuracy of the shaft.

[0061] The above structure solves the problems of unstable rolling, axial movement and insufficient anti-rotation of the traditional bearing seat through multidimensional limiting, accurate lubrication and shock absorption design, and systematically solves the problems of unstable rolling, axial movement and insufficient anti-rotation of the traditional bearing seat, and is suitable for the high reliability support demand of the high-speed rotating components of the carding machine.

[0062] The above embodiments only express several embodiments of the application, and the description is more specific and detailed, but it cannot be understood as a limitation on the patent application scope. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the application, a number of modifications and improvements can be made, which are all within the protection scope of the application. Therefore, the protection scope of the patent of the application should be subject to the appended claims.
