Description

Technical Field

[0001] The utility model relates to the technical field of carding machines, in particular to a supporting and adjusting device for a bearing seat of a carding roller of a carding machine. Background Art

[0002] The aforementioned carding machine is also called a carding machine, which is a component of a complete set of non-woven product production equipment. As known in the industry, a complete set of non-woven product production equipment such as non-woven fabrics or non-woven felts mainly includes an opener, a carding machine, a web laying machine and a needle punching machine. The function of the carding machine is to comb the non-woven fibers opened by the opener and feed them to the web laying machine for web laying. After the web laying machine lays the web, it is sent to the needle punching machine for needle punching or to the water spunlace machine for water spunlace to form a non-woven product.

[0003] Since the prior art can only adjust the combing roller up and down but cannot adjust the combing roller in a circular arc direction, the combing effect of the combing machine is not enough to meet the expectations of the industry.

[0004] For example, the support adjustment device for the opening roller bearing seat of the carding machine disclosed in Chinese patent CN206089905U can adjust the support foot circumferentially by the first and second circumferential adjustment screws, and can adjust the support foot radially by the support foot radial adjustment screws, thereby meeting the requirement for adjusting the gap change between the opening roller and the working roller on the opening roller support bearing seat rotatably supported on the support foot through the bearing.

[0005] However, the bearing pressure plate at the upper end of the support adjustment device is fixed, so that bearings of different sizes cannot be fixed.

[0006] For this reason, we urgently need to provide a support and adjustment device for the bearing seat of the carding roller of the carding machine. Utility Model Content

[0007] The utility model aims to provide a support adjustment device for a combing roller bearing seat of a carding machine to solve the problem that the bearing pressure plate at the upper end of the support adjustment device proposed in the above background technology is fixed, thereby making it impossible to support and adjust bearings of different sizes.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a support and adjustment device for a combing roller bearing seat of a carding machine, comprising a support foot and a positioning block, wherein the positioning block is connected to the lower end of the support foot, and the outer end of the support foot is connected to a supporting mechanism, wherein the supporting mechanism comprises a supporting unit and an adjusting unit, wherein the supporting unit is arranged at the upper end of the support foot, and the adjusting unit is arranged at the lower end of the support foot.

[0009] The supporting unit includes a supporting frame, a first threaded rod, a rotating handle, a bearing and a pressure block. The supporting frame is fixedly connected to the upper side of the support foot, the first threaded rod is connected to the inside of the supporting frame, the rotating handle is fixedly connected to the upper end of the first threaded rod, the bearing is fixedly connected to the outer side of the lower end of the first threaded rod, and the pressure block is fixedly connected to the outer end of the bearing.

[0010] A further improvement is that the left and right ends of the inner side of the support frame are slidably connected to the left and right sides of the pressing block, so that when the pressing block moves, it can slide along the inner side of the support frame, thereby limiting the movement of the pressing block.

[0011] A further improvement is that a threaded hole is provided in the middle of the upper end of the support frame, and the outer side of the first threaded rod is threadedly connected to the inner side of the threaded hole. Thus, when the rotating handle is turned to drive the first threaded rod in the threaded hole to rotate, the first threaded rod can be moved relative to the support frame, thereby driving the pressure block at the lower end to move together, until the pressure block is moved to the upper end of the outer side of the bearing that contacts the upper end of the support foot, so that bearings of different sizes can be fixed to the upper end of the support foot.

[0012] A further improvement is that the adjustment unit includes a second threaded rod, a third threaded rod and a turntable, the second threaded rod is connected to the left and right ends below the support foot, the third threaded rod is connected to the left and right ends above the positioning block, and the turntable is connected to the outer ends of the second threaded rod and the third threaded rod.

[0013] A further improvement is that a first thread groove is provided at the middle position of the left and right ends of the lower part of the support foot, a second thread groove is provided at the middle position of the left and right ends of the upper part of the positioning block, the outer side of the second threaded rod is threadedly connected to the inner side of the first thread groove, the outer side of the third threaded rod is threadedly connected to the inner side of the second thread groove, the end of the second threaded rod away from the support foot and the end of the third threaded rod away from the positioning block are fixedly connected, and the second threaded rod and the third threaded rod are symmetrical, and the turntable is fixed to the outer side of the connection between the second threaded rod and the third threaded rod. Therefore, when the turntable is rotated to drive the second threaded rod and the third threaded rod located in the first thread groove and the second thread groove to rotate, the support foot and the positioning block are driven to move relative to each other, thereby changing the overall length of the support adjustment device, so that the support height of the bearing can be adjusted as required.

[0014] A further improvement is that a fixing bolt is connected inside the positioning block, and a backing plate is connected to the outer end of the fixing bolt, so that the fixing bolt passes through the backing plate and then through the positioning block and then is threadedly connected to the outer end of the carding machine, so that the supporting adjustment device can be installed and fixed as a whole.

[0015] A further improvement is that a rubber pad is fixedly connected to the lower side of the pressing block, so that by moving the pressing block to the upper end of the outer side of the bearing, when the bearing is pressed, the rubber pad on the lower side of the pressing block contacts the outer side of the bearing, so that the bearing can be clamped and fixed more firmly.

[0016] In summary, the present application discloses a support and adjustment device for a bearing seat of a combing roller of a carding machine.

[0017] This technical solution drives the first threaded rod in the threaded hole to rotate by turning the rotating handle, so that the first threaded rod can move relative to the support frame, thereby driving the pressure block at the lower end to move together, until the pressure block is moved to the upper end of the outer side of the bearing that contacts the upper end of the support foot, so that bearings of different sizes can be fixed to the upper end of the support foot.

[0018] Furthermore, by rotating the turntable to drive the second threaded rod and the third threaded rod to rotate in the first thread groove and the second thread groove, the support foot and the positioning block are driven to move relative to each other, thereby changing the overall length of the support adjustment device, so that the support height of the bearing can be adjusted as required.
