[0001] The utility model relates to the technical field of warp knitting machine, specifically a warp knitting machine for corduroy warp knitting interval fabric. BACKGROUND
[0002] The warp knitting machine for corduroy warp knitting interval fabric, including needle bed, its traditional installation structure is: the support shaft of horizontal arrangement is arranged on the rack of warp knitting machine, the lower end of needle bed is provided with fixed clamp, and the movable clamp is clamped to the support shaft under the action of bolt locking, realizes the connection fixed.
[0003] Because the position precision requirement of needle bed in the axial direction of support shaft is relatively high, this precision requirement directly influences the stability of weaving and the quality of woven fabric.
[0004] Therefore, how to overcome the above-mentioned defects has become a problem to be solved by the technical personnel in the field. UTILITY MODEL CONTENTS
[0005] In order to solve the technical problems in the background art, the utility model discloses a warp knitting machine for corduroy warp knitting interval fabric.
[0006] The utility model provides a warp knitting machine for corduroy warp knitting interval fabric, including the rack, the support shaft of horizontal arrangement is installed on the rack, the needle bed is installed on the support shaft, the lower end of needle bed is provided with two fixed clamps of symmetrical arrangement, and the movable clamp is clamped to the support shaft with fixed clamp, and is fixedly connected through bolt locking.
[0007] The movable clamp is fixedly installed on the screw nut of screw rod,
[0008] By driving the rotation of screw rod, the position of movable clamp in the axial direction of support shaft can be adjusted.
[0009] When the position of needle bed needs to be adjusted, only the rotation of screw rod is driven, which can drive needle bed to produce displacement in the axial direction of support shaft.
[0010] Since the two fixed clamps are fixed in position, the relative position error of the corresponding movable clamp on the same lead screw is large, and it is difficult to accurately connect with the fixed clamp. Based on this, the further improvement is that the lead screw is provided as a coaxially arranged first lead screw and a second lead screw; the first lead screw and the second lead screw are both threadedly connected with a lead screw nut.
[0011] The specific mounting structure of the lead screw nut and the movable clamp is that the lower end of the support shaft is provided with two symmetrically arranged notches; the lower end of the lead screw nut is connected with a connecting block, the connecting block passes through the notches and is fixedly connected with the movable clamp; the two sides of the connecting block abut against the groove walls of the notches, also playing a guiding and limiting role, so that the movable clamp can stably move in the axial direction of the support shaft and will not rotate to cause position deviation.
[0012] Since the warp knitting machine will vibrate during operation, and the movable clamp is connected with the lead screw nut and the lead screw through threads, the position of the movable clamp is unstable, which can easily cause the position of the needle bed to deviate. Based on this, the further improvement is that the lower end face of the connecting block is arc-shaped, the diameter thereof is equal to the diameter of the support shaft, and the connecting block is coaxial with the support shaft; when the movable clamp is locked and fixed with the fixed clamp, radial pressure is generated between the lead screw nut and the lead screw. In this way, the radial pressure between the lead screw nut and the lead screw forms resistance to the movement of the lead screw nut, so that the position of the lead screw nut is fixed, thereby improving the position stability of the needle bed.
[0013] It is difficult to install the first lead screw and the second lead screw in the support shaft, based on this, the further improvement is that the support shaft is spliced from a coaxially arranged first shaft segment and a second shaft segment; the first lead screw is installed in the first shaft segment; the second lead screw is installed in the second shaft segment; the lower end of the first shaft segment and the second shaft segment is provided with a notch.
[0014] The specific connection structure of the first shaft segment and the second shaft segment is that the inner end of the first shaft segment is provided with a first connecting plate; the inner end of the second shaft segment is provided with a second connecting plate, which is connected and fixed with the first connecting plate through a fastener.
[0015] Since the space between the needle bed and the support shaft is small, there is not enough space to accommodate the first connecting plate and the second connecting plate, based on this, the further improvement is that the first connecting plate is located below the axis of the first shaft segment, and the second connecting plate is located below the axis of the second shaft segment.
[0016] The coaxiality of the first shaft segment and the second shaft segment directly affects the stability of the mounting structure and the installation position accuracy of the needle bed, based on this, the further improvement is that the first connecting plate is provided with a non-circular positioning groove; the second connecting plate is provided with a positioning block clamping the positioning groove. The positioning groove is non-circular, which can also avoid relative rotation between the first shaft segment and the second shaft segment.
[0017] The utility model discloses beneficial effect is: when needing to adjust the position of needle bed, only need to drive the rotation of screw rod, can drive needle bed and produce displacement in the axial direction of support shaft, the above -mentioned setting, not only convenient adjustment, and through the rotation of screw rod adjustment, control precision is higher, thereby shortens the adjustment time of needle bed, indirectly improves production efficiency and product quality.

DETAILED DESCRIPTION
[0027] Now in combination with the drawings to the utility model makes further detailed explanation.These drawings are all simplified schematic diagram, just with the schematic way to show the basic structure of the utility model, so it just shows the constitution related to the utility model.
[0028] As Figure 1 The utility model discloses a kind of warp knitting machines for corduroy warp-knitted spacer fabric, including rack 1, rack 1 is installed with horizontally arranged support shaft 2, the upper end of support shaft 2 is installed with needle bed 3. The lower end of needle bed 3 is provided with two symmetrical fixed clasp 4 of arrangement, movable clasp 5 and fixed clasp 4 are clamped support shaft 2, bolt passes through movable clasp 5, and is threadedly connected with fixed clasp 4, and locking realizes fixed clasp 4 and movable clasp 5 fixed connection.
[0029] As Figures 2-4 Shown, support shaft 2 is spliced by coaxially arranged first shaft section 21 and second shaft section 22, and its specific connection structure is: the inner end of first shaft section 21 is provided with first connecting plate 23;The inner end of second shaft section 22 is provided with second connecting plate 24, and is connected and fixed with first connecting plate 23 by fastener.As Figures 5-7 Shown, first connecting plate 23 is provided with non-circular positioning slot 25;Second connecting plate 24 is provided with positioning block 26 of clamping positioning slot 25. Positioning slot 25 adopts non-circular, also can avoid relative rotation between first shaft section 21 and second shaft section 22. In the embodiment, positioning slot 25 and positioning block 26 are both long circle.
[0030] Because the space between needle bed 3 and support shaft 2 is small, it does not have enough space to accommodate first connecting plate 23 and second connecting plate 24, so first connecting plate 23 is located below the axis of first shaft section 21, and second connecting plate 24 is located below the axis of second shaft section 22.
[0031] First screw rod 7 is installed in first shaft section 21, bearings are installed at the two ends of first shaft section 21, the inner end of first screw rod 7 is inserted into the inner end bearing, and the outer end of first screw rod 7 passes through the outer end bearing and is connected with hand wheel 10;Second screw rod 8 is installed in second shaft section 22, bearings are installed at the two ends of second shaft section 22, the inner end of second screw rod 8 is inserted into the inner end bearing, and the outer end of second screw rod 8 passes through the outer end bearing and is connected with hand wheel 10. Hand wheel 10 is used to conveniently drive the rotation of the screw rod.
[0032] Screw nut 6 is threadedly connected to first screw rod 7 and second screw rod 8. The lower end of first shaft section 21 and second shaft section 22 is provided with a notch 9, and the length direction of notch 9 extends axially along support shaft 2. The lower end of screw nut 6 is connected with an integrally formed connecting block 11, and two symmetrical bolts pass through movable clasp 5 and are threadedly connected with connecting block 11. The two sides of connecting block 11 abut against the groove wall of notch 9, which also plays a guiding and limiting role, so that movable clasp 5 can stably move in the axial direction of support shaft 2 and will not rotate to cause position deviation.
[0033] Because the warp knitting machine will produce vibration when working, and the movable clamp 5 is connected with the screw rod through the screw nut 6 and the screw thread, the position of the movable clamp 5 is unstable, which can easily lead to the deviation of the position of the needle bed 3, therefore, the lower end surface of the connecting block 11 is arc-shaped, the diameter of which is equal to the diameter of the supporting shaft 2 and coaxial with the supporting shaft 2; when the movable clamp 5 is locked and fixed with the fixed clamp 4, the radial pressure is generated between the screw nut 6 and the screw rod. In this way, the radial pressure between the screw nut 6 and the screw rod forms the resistance of the movement of the screw nut 6, so that the position of the screw nut 6 is fixed, thereby improving the position stability of the needle bed 3.
[0034] The above setting can adjust the position of the movable clamp 5 in the axial direction of the supporting shaft 2 by driving the screw rod to rotate. When the position of the needle bed 3 needs to be adjusted, the needle bed 3 can be driven to displace in the axial direction of the supporting shaft 2 by driving the screw rod to rotate. The above setting is not only convenient to adjust, but also has small adjustment range and high control precision by adjusting the screw rod to rotate, thereby shortening the adjustment time of the needle bed 3 and indirectly improving the production efficiency and product quality.
[0035] Based on the above ideal embodiments of the present application, the related personnel can make various changes and modifications without deviating from the technical idea of the present application according to the above description. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of the claims.
