Description

Technical Field

[0001] The utility model belongs to the technical field of looms, and in particular relates to a wide-shaft loom. Background Art

[0002] With the development of the market, people's requirements for fabrics are becoming more and more diverse. For example, some geotextiles are required to be changed from small sizes to large sizes in order to facilitate their use on construction sites and reduce the frequency of laying.

[0003] This requires a loom with a wide warp let-off range. Wide-width looms are much more expensive than standard looms, which means using wide-width looms would incur significant production costs, and the existing standard looms would also reduce their operating time. Therefore, the idea of reassembling two standard looms into one wide-width loom emerged, which would save costs.

[0004] However, during the use process after the modification, most of the parts of the loom can be used through transfer, splicing or replacement. Only the two warp-letting shafts are large in size and weight, and require a large driving torque, which causes the coupling used to connect the two warp-letting shafts to be often damaged (the two warp-letting shafts are regarded as a single shaft after being connected by the coupling, and are driven by the drive system on one side of the single shaft), affecting the normal use of the loom. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a wide-axis loom, which is used to solve the technical problem in the prior art that the warp shaft of the modified wide-axis loom is often damaged due to the large driving torque, thereby affecting the normal use of the loom.

[0006] The utility model solves the above technical problems with the following technical solutions: A wide-axis loom comprising:

[0007] A frame, the frame comprising two side plates and a middle plate, the middle plate dividing the space between the two side plates into a left shaft area and a right shaft area;

[0008] Two let-off beams, which are arranged in parallel and are respectively arranged in the left axis area and the right axis area, and each of the let-off beams is further provided with a large gear;

[0009] A transmission assembly is provided on the frame and passes through the left shaft area and the right shaft area, and the transmission assembly synchronously drives the two warp let-off beams.

[0010] The utility model utilizes an intermediate plate to arrange two let-off beams in parallel, and then utilizes a transmission component to synchronously drive the two let-off beams, thereby realizing synchronous warp let-off and increasing the width range of the warp let-off.

[0011] Furthermore: the transmission assembly includes:

[0012] A motor assembly, the motor assembly comprising a reducer and a motor, the output shaft of the motor being connected to the reducer, and the reducer being fixedly connected to the outer side of the side plate in the right shaft area;

[0013] A double-gear shaft, the double-gear shaft is connected to the reducer, the double-gear shaft includes a first gear and a second gear, the first gear is meshed with the large gear of the let-off shaft in the right shaft area;

[0014] A transmission shaft passes through the right shaft area, and a third gear and a fourth gear are provided on the transmission shaft. The third gear is provided in the right shaft area, and the fourth gear is provided in the left shaft area. The third gear is engaged with the second gear, and the fourth gear is engaged with the large gear of the warp-feeding shaft in the left shaft area.

[0015] The beneficial effect of adopting this step is: using the double-gear shaft as the main power shaft, driving the large gear and transmission shaft in the right shaft area at the same time, and the transmission shaft can drive the large gear in the left shaft area, and finally making the two large gears in the left and right shaft areas rotate synchronously.

[0016] Furthermore: a bridge gear is provided between the large gear of the warp let-off shaft in the left shaft area and the fourth gear;

[0017] The rotating shaft of the bridge gear is arranged on the middle plate.

[0018] The beneficial effect of adopting this step: In order to reduce the difficulty of processing, it is necessary to make the gear parameters on the dual-gear shaft and the transmission shaft consistent, but this will cause the fourth gear on the transmission shaft to not mesh with the large gear in the left shaft area. At this time, a bridge gear is needed to realize the function of bridge transmission.

[0019] Furthermore: the dual gear shaft is fixed or movable;

[0020] The fixed dual-gear shaft, the first gear and the second gear are arranged on the same shaft;

[0021] The movable double-gear shaft has the first gear disposed on a shaft sleeve, the second gear disposed on a shaft rod, and the shaft rod is inserted into the shaft sleeve.

[0022] Beneficial effects of this step: Fixed or movable double-gear shafts each have their own advantages and can be selected based on actual processing capabilities and usage conditions.

[0023] Furthermore: guard plates are provided at both ends of the warp let-off shaft, and the large gear is located outside the guard plates.

[0024] The beneficial effect of adopting this step is that the guard plate can separate the warp yarn from the large gear, preventing the warp yarn from being entangled in the large gear.

[0025] Furthermore, the middle plate is formed by splicing two vertical plates and two horizontal plates, the two vertical plates are parallel and have a distance therebetween, and the distance is used to place the shaft heads of the two let-off beams.

[0026] The beneficial effect of adopting this step is that the middle plate can properly fix the adjacent shaft heads of the two parallel let-off beams.

[0027] The beneficial effects of the utility model are:

[0028] 1. The transmission assembly composed of a transmission shaft, a double gear shaft and other parts can drive two warp let-off beams at the same time, allowing the two warp let-off beams to rotate synchronously;

[0029] 2. The transmission component actually has two power output ends. Compared with the two let-off beams themselves, each let-off beam has a single power source. It is only because the two power output ends can output power synchronously that the two let-off beams can rotate synchronously. In this way, there is no need for a coupling to connect the two let-off beams, and the operation is more stable and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Example

[0046] like Figure 1 As shown, the utility model provides a wide-axis loom, comprising:

[0047] The frame includes two side panels 1 and a middle panel 2, wherein the middle panel 2 separates the space between the two side panels 1 into a left shaft area 11 and a right shaft area 12;

[0048] Two let-off beams 3, which are arranged side by side and are respectively arranged in the left axis area 11 and the right axis area 12, and each let-off beam 3 is further provided with a large gear 31;

[0049] A transmission assembly is provided on the frame and passes through the left shaft area 11 and the right shaft area 12 , and the transmission assembly synchronously drives the two warp let-off beams 3 .

[0050] The utility model utilizes the middle plate 2 to arrange the two let-off shafts 3 in parallel, and then utilizes the transmission component to synchronously drive the two let-off shafts 3, thereby realizing synchronous warp let-off and increasing the width range of the warp let-off.

[0051] The distance between the two let-off beams 3 caused by the intermediate plate 2 prevents them from being placed close together. Therefore, the warp yarns on the let-off beams 3 are arranged at an angle, with the warp yarns moving from the sides toward the center. The warp yarns pass through the healds on the heald frames and then through the reed to form cloth. The two let-off beams 3 arranged side by side and at a distance from each other do not affect the warp let-off effect.

[0052] On the basis of the above technical solution, the transmission assembly includes:

[0053] A motor assembly 4, comprising a reducer and a motor, wherein the output shaft of the motor is connected to the reducer, and the reducer is fixedly connected to the outer side of the side plate 1 of the right shaft area 12;

[0054] The double gear shaft 5 passes through the side plate 1 of the right shaft area 12, and then the double gear shaft 5 is connected to the reducer. The double gear shaft 5 includes a first gear 51 and a second gear 52. The first gear 51 is engaged with the large gear 31 of the let-off shaft 3 of the right shaft area 12;

[0055] The transmission shaft 6 passes through the right shaft area 12, and a third gear 61 and a fourth gear 62 are provided on the transmission shaft 6. The third gear 61 is provided in the right shaft area 12, and the fourth gear 62 is provided in the left shaft area 11. The third gear 61 is engaged with the second gear 52, and the fourth gear 62 is engaged with the large gear 31 of the warp-feeding shaft 3 of the left shaft area 11.

[0056] The dual-gear shaft 5 is used as the main power shaft to simultaneously drive the large gear 31 of the right shaft area 12 and the transmission shaft 6, and the transmission shaft 6 can drive the large gear 31 of the left shaft area 11, ultimately making the two large gears 31 of the left shaft area 11 and the right shaft area 12 rotate synchronously.

[0057] like Figure 2 and Figure 3 As shown, a bridge gear 7 is further provided between the large gear 31 of the let-off shaft 3 of the left shaft area 11 and the fourth gear 62;

[0058] The rotating shaft of the axle gear 7 is arranged on the intermediate plate 2 .

[0059] like Figure 3 As shown, in order to reduce the difficulty of processing, it is necessary to make the gear parameters on the dual-gear shaft 5 and the transmission shaft 6 consistent. However, this will cause the fourth gear 62 on the transmission shaft 6 to not mesh with the large gear 31 of the left shaft area 11. At this time, there are two solutions. One is to use the fourth gear 62 represented by the dotted line to directly mesh with the large gear 31, but the wheel diameter of the fourth gear 62 represented by the dotted line must be increased. The other is to use the fourth gear 62 represented by the dotted line and the bridge gear 7 to mesh with the large gear 31 through the bridge gear 7. The bridge gear 7 has the same parameters as the first gear 51 and the second gear 52 on the dual-gear shaft 5.

[0060] In this embodiment, the bridge gear 7 is preferably used.

[0061] like Figure 4 and Figure 5 As shown, the dual gear shaft 5 is fixed or movable;

[0062] The fixed dual-gear shaft 5, the first gear 51 and the second gear 52 are arranged on the same shaft body 53;

[0063] In the movable double-gear shaft 5 , the first gear 51 is provided on a shaft sleeve 54 , and the second gear 52 is provided on a shaft rod 55 , and the shaft rod 55 is inserted into the shaft sleeve 54 .

[0064] Fixed or movable double gear shafts each have their own advantages and can be selected according to actual processing capabilities and usage conditions.

[0065] On the basis of the above technical solution, guard plates 32 are provided at both ends of the let-off beam 3 , and the large gear 31 is located outside the guard plates 32 .

[0066] The guard plate 32 can separate the warp yarn from the large gear 31 to prevent the warp yarn from being drawn into the large gear 31 .

[0067] On the basis of the above technical solution, the middle plate 2 is spliced by two vertical plates and two horizontal plates. The two vertical plates are parallel and have a spacing 21 therebetween. The spacing 21 is used to place the shaft heads of the two let-off beams 3 .

[0068] The two shaft heads must be able to rotate freely without interfering with each other, and the middle plate 2 can properly fix the adjacent shaft heads of the two parallel let-off beams, allowing them to rotate freely without interfering with each other.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
