Description

Technical Field

[0001] The utility model relates to the technical field of warping machines, in particular to a yarn tube supporting mechanism for a warp frame of a warping machine. Background Art

[0002] The warp frame is the warp feeding mechanism on textile machinery, which can transfer chemical fibers from the yarn bobbin to warping machines, textile machines and other textile machinery for use. It is generally composed of steel pipes or steel sections as the skeleton, and support shafts and support plates for rows and columns of warp yarn tubes.

[0003] According to patent No. 202021753572.4, a warp frame for a warping machine includes a fixed base plate, two of which are provided, and electric telescopic rods are installed on the tops of the two fixed base plates near the front and rear edges. There are four electric telescopic rods in total, which are divided into two groups. A fixed long plate is welded between the tops of the two electric telescopic rods in each group, and there are two fixed long plates in total.

[0004] The above patent achieves this by slidingly sleeveing ​​the yarn drum on the outer surface of the round rod, and making the bottom of the yarn drum contact with the tops of multiple sliding beads. When the yarn drum rotates rapidly, the rotation of the sliding beads can effectively reduce the friction of the yarn drum, thereby facilitating the rapid rotation of the yarn drum. At the same time, after the yarn drum is slidably sleeved, the threaded block is threadedly sleeved on the top of the round rod, thereby limiting the position of the yarn drum. In use, it effectively prevents the yarn drum from falling off the round rod, making it easy to use.

[0005] However, each time the yarn tube needs to be replaced, the threaded block needs to be removed, and after the yarn tube is installed, the threaded block needs to be screwed on, which is troublesome. In addition, multiple yarn tubes are arranged on the warp frame, and each of them needs such operation, which makes the operation very cumbersome and the work efficiency poor. For this reason, we provide a yarn tube support mechanism for the warp frame of a warping machine to solve this problem. Utility Model Content

[0006] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a technical solution for solving the above-mentioned problems by providing a yarn tube supporting mechanism for a warp frame of a warping machine.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A yarn bobbin support mechanism for a warp frame of a warping machine comprises a chassis, a fixing column is installed on the upper end of the chassis, convex grooves are arranged at equal intervals along the circumferential direction on the upper end of the chassis, the inner cavities of the convex grooves are all slidably connected to limit mechanisms, and a rotation speed detection component is installed on the upper end of one of the limit mechanisms;

[0009] The limiting mechanism includes a convex block slidably connected to the inner cavity of the convex groove, a fixing groove is provided on one side of the convex block, a second mounting ring is installed in the inner cavity of the fixing groove, one end of the second mounting ring is connected to the first mounting ring through an elastic connecting piece, the first mounting ring is installed in the inner cavity of the convex groove, a concave plate is installed at the upper end of the convex block, a support shaft is rotatably connected to the lower end of the inner cavity of the concave plate, rolling balls are equidistantly installed on the support shaft, the upper end of the concave plate is connected to a top plate, and a bearing seat rotatably connected to the support shaft is installed on the top plate.

[0010] As a further solution of the utility model: the rotation speed detection component includes a mounting seat installed on the upper end of a top plate, and a magnetoelectric rotation speed sensor is installed in the inner cavity of the mounting seat.

[0011] As a further solution of the utility model: the upper end of the top plate is symmetrically connected with a guide plate, and the upper end surface of the guide plate is a slope.

[0012] As a further solution of the utility model: an arc-shaped sliding groove is arranged at the lower end of the concave plate, and an arc-shaped strip slidingly connected therewith is installed in the inner cavity of the convex groove.

[0013] As a further solution of the utility model: a socket is provided on the outer side of the convex block, a plug rod is movably inserted into the inner cavity of the socket, a threaded groove corresponding to its position is installed in the inner cavity of the convex groove, and one end of the plug rod passes through the elastic connecting piece and the first mounting ring and is screwed into the threaded groove.

[0014] As a further solution of the utility model: a plurality of groups of arc-shaped rings are integrally welded to the outer side of the fixing column.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. Multiple arc rings are designed on the outside of the fixed column to fit with the inner wall of the yarn tube, so as to avoid the entire fixed column from fitting with the inner wall of the yarn tube, effectively reducing the resistance when the yarn tube rotates, and the yarn tube is clamped by the limit mechanism. When the yarn tube rotates and arranges the wires, the yarn on the outside rubs against the rolling ball, driving the rolling ball to rotate, and the rolling ball drives the support shaft to rotate. When the yarn becomes less and less, the thickness of the yarn on the outside of the yarn tube gradually becomes thinner, and the stretched elastic connector drives the convex block and the concave plate to move and reset synchronously, and the rolling ball is always close to the yarn on the outside of the yarn tube, which effectively improves the clamping effect, facilitates and effectively limits the yarn tube to prevent it from falling off, and is easy to use;

[0017] 2. When the yarn drum is rotated to arrange the wire, the yarn drum drives the ball to roll, and the ball drives the support shaft to rotate, and then one end of the magnetoelectric speed sensor detects that the support shaft is rotating at a certain speed. When the yarn wrapped around the outside of the yarn drum is exhausted, the yarn drum will not be able to rotate, and the support shaft will not be able to rotate. Subsequently, the magnetoelectric speed sensor cannot detect the rotation speed of the support shaft, and then transmits this information to the external control system, so that the control system can issue an alarm and the staff can replace the yarn drum in time, which effectively improves the use effect.

[0028] The upper end of the top plate 38 is symmetrically connected to a guide plate 39 , and the upper end surface of the guide plate 39 is a slope surface.

[0029] An arc-shaped slide groove 37 is provided at the lower end of the concave plate 31, and an arc-shaped strip 6 which is in sliding contact with the convex groove 2 is installed in the inner cavity.

[0030] When the yarn drum is sleeved on the fixed column 4, the lower end of the yarn drum sleeve is pressed against the surface of the guide plate 39 at the upper end of the plurality of limit mechanisms 3, and the upper surface of the guide plate 39 is a slope, which is convenient for the yarn drum to be pushed downward, and the guide plate 39 is pushed outward, thereby introducing the yarn drum into the outer side of the fixed column 4, effectively improving the use effect, and in this process, the guide plate 39 drives the top plate 38 and the concave plate 31 to move outward, and then the convex block 32 at the lower end of the concave plate 31 moves in the inner cavity of the convex groove 2, and the convex block 32 slides stably on the outer side of the arc strip 6 through the arc-shaped slide groove 37 at its lower end, and at the same time, the concave plate 31 drives the second mounting ring 10 to move outward while pulling the elastic connecting piece 8, and when the yarn drum is completely sleeved on the outer side of the fixed column 4, the concave plate 31 The elastic connecting member 8 is driven to move to the farthest position. When the yarn drum is rotating to arrange the wire, the yarn drum rotates, and the yarn on the outside thereof rubs against the ball 34, driving the ball 34 to rotate, and the ball 34 drives the support shaft 33 to rotate. At the same time, when the yarn becomes less and less, the thickness of the yarn on the outside of the yarn drum gradually becomes thinner, and then the stretched elastic connecting member 8 is reset and contracted, and the elastic connecting member 8 drives the convex block 32 and the concave plate 31 to move synchronously, so that the ball 34 is always close to the yarn on the outside of the yarn drum, which effectively improves the clamping effect, and multiple limiting mechanisms 3 clamp the yarn drum, and at the same time, the ball 34 is in rolling contact with the yarn on the outside of the yarn drum, so as to avoid affecting the rotation of the yarn drum, and conveniently and effectively limit the yarn drum and prevent it from falling off, which is easy to use.

[0031] A socket 36 is provided on the outer side of the convex block 32, and an insert rod 9 is movably inserted into the inner cavity of the socket 36. A threaded groove 11 corresponding to its position is installed in the inner cavity of the convex groove 2. One end of the insert rod 9 passes through the elastic connecting piece 8 and the first mounting ring 7 and is screwed to the threaded groove 11.

[0032] The insertion rod 9 passes through the insertion hole 36 on the outer side of the convex block 32 and is screwed and fixed with the thread groove 11, so that the convex block 32 can be effectively supported by the movable insertion, thereby improving the stability of the movement of the convex block 32.

[0033] A speed detection component is installed at the upper end of one of the limit mechanisms 3, and the speed detection component includes a mounting seat 14 installed at the upper end of the top plate 38. A magnetoelectric speed sensor 13 is installed in the inner cavity of the mounting seat 14. The upper end of a support shaft 33 passes through the bearing seat 310 and extends above it. One end of the magnetoelectric speed sensor 13 is installed at a distance of 0.5-1.5mm from the outer side of the support shaft 33.

[0034] When the yarn drum is rotating to arrange the wire, the yarn drum drives the ball 34 to roll, and the ball 34 drives the support shaft 33 to rotate, and then one end of the magnetoelectric speed sensor 13 detects that the support shaft 33 is rotating at a certain speed. When the yarn wrapped around the outside of the yarn drum is finished, the yarn drum will not be able to rotate, and then the support shaft 33 will not be able to rotate. Subsequently, the magnetoelectric speed sensor 13 cannot detect the rotation speed of the support shaft 33, and then transmits this information to the external control system, so that the control system can send out an alarm, so that the staff can replace the yarn drum in time, and the use effect is effectively improved.

[0035] A fixed column 4 is installed at the upper end of the chassis 1, and several groups of arc rings 5 ​​are integrally welded to the outer side of the fixed column 4. By sleeve-fitting the yarn tube on the outer side of the fixed column 4 and designing multiple arc rings 5 ​​to fit with the inner wall of the yarn tube, the entire fixed column 4 is prevented from fitting with the inner wall of the yarn tube, thereby effectively reducing the resistance of the yarn tube when it rotates.

[0036] Working principle: When the yarn tube is sleeved on the fixed column 4, the lower end of the yarn tube sleeve is pressed against the surface of the guide plate 39 at the upper end of the plurality of limit mechanisms 3, and then when the yarn tube is pushed downward, the guide plate 39 is pushed to move outward, and then the yarn tube is introduced and inserted into the outer side of the fixed column 4. In this process, the guide plate 39 drives the top plate 38 and the concave plate 31 to move outward, and then the convex block 32 at the lower end of the concave plate 31 moves in the inner cavity of the convex groove 2, and at the same time, the concave plate 31 drives the second mounting ring 10 to move outward while pulling the elastic connecting member 8. When the bobbin is completely sleeved on the outside of the fixed column 4, multiple arc rings 5 ​​are designed to fit with the inner wall of the bobbin to prevent the entire fixed column 4 from fitting with the inner wall of the bobbin, effectively reducing the resistance of the bobbin when it rotates, and the concave plate 31 drives the elastic connector 8 to move to the farthest position. When the bobbin is rotating to arrange the wire, the bobbin rotates, and the yarn on the outside rubs against the ball 34, driving the ball 34 to rotate, and the ball 34 drives the support shaft 33 to rotate. At the same time, when the yarn becomes less and less, the yarn thickness on the outside of the bobbin gradually becomes thinner, thereby pulling The elastic connecting member 8 is stretched to reset and shrink, and the elastic connecting member 8 drives the convex block 32 and the concave plate 31 to move synchronously, so that the ball 34 is always close to the yarn on the outside of the yarn tube, which effectively improves the clamping effect, and multiple limiting mechanisms 3 clamp the yarn tube, and at the same time, the ball 34 is in rolling contact with the yarn on the outside of the yarn tube, so as to avoid affecting the rotation of the yarn tube, and conveniently and effectively limit the yarn tube to prevent it from falling off, which is convenient for use. When the yarn tube is rotating and arranging the wire, the yarn tube drives the ball 34 to roll, and the ball 34 drives the support shaft 33 to rotate, and then one end of the magnetoelectric speed sensor 13 detects that the support shaft 33 is rotating, and has a certain speed. When the yarn wrapped around the outside of the yarn tube is exhausted, the yarn tube will not be able to rotate, which will cause the support shaft 33 to be unable to rotate. Subsequently, the magnetoelectric speed sensor 13 cannot detect the rotation speed of the support shaft 33, and then transmits this information to the external control system, so that the control system can send out an alarm, so that the staff can replace the yarn tube in time, which effectively improves the use effect.
