Description

Technical Field

[0001] The utility model relates to the technical field of multi-axial warp knitting machines, in particular to a material blocking device and a multi-axial warp knitting machine. Background Art

[0002] The winding method of the multi-axial warp knitting machine is to bond the fabric and the paper tube by pasting double-sided tape, and then put an iron roller inside the paper tube and place it on the winding curling roller by adding weight for passive winding.

[0003] When winding, the paper tube often deviates left and right on the winding roller, thus affecting the deviation of the fabric winding and causing uneven winding. In order to avoid the left and right deviation of the paper tube during winding, the tension control system can be optimized, especially in the winding stage, the tension should be kept constant to reduce the uneven pulling of the fabric caused by tension changes. Some multi-axial warp knitting machines are also equipped with automatic centering or locking devices, which are more complex in structure.

[0004] Putting an iron roller inside a paper tube causes inconvenience in operation and safety risks during the unwinding and rewinding process. Specifically, when unwinding, two people are required to hold down the fabric at both ends, and two people in the middle lift the paper tube equipped with an iron rod to press the fabric and roll it into the winding roller. A total of four people are required to complete the unwinding operation; if the fabric tension is uneven, the paper tube equipped with the iron rod needs to be moved out and then put back in. Repeated operations can easily cause fabric shrinkage. When rewinding, due to the weight of the full piece of fabric and the iron rod itself, two people are required to work together to move the fabric out of the winding roller with their palms. Due to the force of the palm, when moving low-weight fabrics, palm prints are usually left, causing the fabric surface to sag. In addition, the iron rod is in a slidable state in the paper tube. If two people lift it to different heights, or one person accidentally slips, it is easy to slide outward from the lower end. If it falls to the ground, there is a risk of injuring limbs or the ground.

[0005] How to solve the problem of uneven winding and avoid inconvenience in the winding and unwinding process is our direction of improvement. Summary of the invention

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] It should be noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", "up", "down", "inside", "outside", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention rather than requiring that the present invention must be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. The terms "front", "rear", "left", "right", "up", and "down" used in the description of the present invention refer to the directions in the accompanying drawings, and the terms "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0033] The material blocking device of the present application is manufactured by manufacturing a material blocking component and installed on the wall panels at both ends of the winding roller of the equipment. The device can be used to control the fabric paper tube to be wound at a fixed position of the winding roller, thereby preventing the paper tube from deviating left and right on the winding roller and causing the fabric to deviate, thereby achieving the purpose of neat winding.

[0034] The baffle 2 of the present application can be turned 90°; when unwinding, the left baffle is turned away, and then the paper tube is installed on the fabric winding roller and the iron roller is inserted from the left to complete the unwinding; the unwinding problem in the first operational difficulty can be solved. The baffle 2 of the present application can be turned 90°; when rewinding, the left baffle is turned away, and the iron rod is pulled out from the paper tube and then the fabric is removed; the rewinding problem in the second operational difficulty can be solved.

[0035] like Figure 1 and Figure 2 As shown, the present application discloses a material blocking device, including a material blocking assembly arranged at both axial ends of a paper tube; the material blocking assembly includes a crossbeam frame 1, a baffle 2, a baffle bracket 3 and a flip mechanism 4, the crossbeam frame 1 is installed on the frame, the baffle bracket 3 is connected to the crossbeam frame 1, and the end of the baffle bracket 3 is connected to the baffle 2 through the flip mechanism 4; the baffle 2 has a first state and a second state, in the first state, the baffle 2 is attached to the end of the paper tube and blocks the central axis hole of the paper tube; in the second state, the baffle 2 is away from the paper tube; a weight-increasing member is detachably connected to the central axis hole of the paper tube.

[0036] In the present application, the baffle 2 is attached to the end of the paper tube, which means that it is attached to the end of the paper tube in the axial direction. The attachment in the present application means that the baffle 2 just touches the end of the paper tube, does not press the end of the paper tube, and does not hinder the rotation of the paper tube. In the second state, the baffle 2 is away from the paper tube, and the baffle 2 does not hinder the axial movement of the paper tube.

[0037] The present application can conveniently reel in and out by adjusting the baffle plate 2 to switch between the first state and the second state. During the reeling process, the baffle plate is placed in the first state to ensure neat reeling. The two baffle components can simultaneously ensure neat reeling and convenient reeling and unreeling, and the structure is simple.

[0038] Specifically, when unwinding, after the paper tube is installed, the baffle on one side is placed in the first state, and the baffle on the other side is placed in the second state, the weight-increasing member is installed into the paper tube through the side of the baffle in the second state, and then the paper tube on this side is placed in the first state, thereby completing the subsequent unwinding operation. When rewinding, the baffles on both sides are placed in the second state, and the weight-increasing member is removed to complete the subsequent rewinding operation.

[0039] The flipping mechanism 4 of the present application only needs to be able to adjust the position of the baffle 2 , and may be a connecting rod type flipping mechanism, a torsion bar type flipping mechanism, a belt flipping mechanism, a hydraulic flipping mechanism, or the like.

[0040] In one embodiment, the flipping mechanism is described in detail. Figure 2As shown, the flip mechanism 4 includes an inner joint 402 and an outer joint 401 connected to the baffle bracket 3, the inner joint 402 and the outer joint 401 are connected by a connecting pin 403; the baffle 2 is connected to the main rod of the inner joint 402. The joint-type flip mechanism design has a simple structure, light weight, and is convenient for the user to place the baffle in the first state and the second state.

[0041] like Figure 2 As shown, Figure 2 (a) is a schematic diagram of the position of the baffle 2 in the first state, Figure 2 (b) is a schematic diagram of the position of the baffle 2 in the second state. The baffle 2 in the first state is perpendicular to the baffle 2 in the second state. This design makes the distance between the baffles in the first state and the second state longer, which will not hinder the installation and removal of the weight-increasing member.

[0042] Furthermore, in the first state, the baffle bracket 3 and the main rod of the inner joint 402 are in the same straight line, and in the second state, the baffle bracket 3 and the main rod of the inner joint 402 are perpendicular. This design facilitates the adjustment of the position of the main rod of the inner joint 402 and the baffle bracket 3 through the inner joint and the outer joint, and facilitates the switching of the position of the baffle 2.

[0043] In a further embodiment, the baffle 2 is welded to the main rod of the inner joint 402 to ensure the stability of the connection of the baffle 2. The baffle bracket 3 and the crossbeam frame 1 are connected by screws 5 and nuts 6. This design allows for easy disassembly of the baffle bracket 3 without hindering maintenance of the multi-axial warp knitting machine.

[0044] In one embodiment, the weight-increasing member is an iron roller; the iron roller is inserted into the central axis hole of the paper tube, and the outer diameter of the iron roller is slightly smaller than the inner diameter of the central axis hole of the paper tube, so as to ensure the convenience of inserting the iron roller and reduce the shaking of the iron roller in the paper tube.

[0045] In a further embodiment, Figure 3 As shown, Figure 3 (a) is a schematic diagram of the position of the baffle 2 in the first state, Figure 3 (b) is a schematic diagram of the position of the baffle 2 in the second state. A connecting ear 7 is provided at one end of the baffle bracket 3 close to the outer joint 401, and a connecting ear 7 is provided on the main rod of the inner joint 402; in the second state, the connecting ear on the baffle bracket 3 and the connecting ear on the main rod are connected by a connecting rod. This design allows the baffle 2 to remain in the second state, preventing the automatic change of the position of the baffle 2 when no operation is performed.

[0046] Furthermore, a torsion spring is provided on the connecting pin 403. In the first state, the torsion spring is in a natural state, and in the second state, the torsion spring is compressed or stretched. This design allows the baffle 2 to remain in the first state in the absence of external force. When the baffle is in other states, after the external force is removed, the baffle will automatically return to the first state under the action of the torsion spring. A further improvement of the present application is that the movable winding device is installed on the wall panels at both ends of the winding roller through the crossbeam frame-1, and the fabric paper tube can be controlled by the device to be wound at a fixed position of the winding roller; the paper tube is prevented from deviating left and right on the winding roller to cause the fabric to deviate, thereby achieving the purpose of neat winding.

[0047] A further improvement of the present application is that the movable baffle device is designed with a welding flip device-4 so that the baffle-2 can be flipped 90 degrees, thereby simplifying the unwinding operation, which requires many people and is difficult to operate and causes fabric shrinkage.

[0048] A further improvement of the present application is that the movable baffle device is designed with a welding flipping device-4 so that the baffle-2 can be flipped 90 degrees, thereby solving the problem of fingerprints left on the surface of the fabric due to excessive palm force during the winding operation.

[0049] A further improvement of the present application is that the movable baffle device is designed with a welded flipping device-4 so that the baffle-2 can be flipped 90°, and the paper tube can be inserted first and then the iron rod can be inserted to avoid the risk of employees slipping and falling and getting injured when lifting it to different heights.

[0050] The assembly process of the material blocking device of the present application includes the following steps:

[0051] Step 1: Under the curling roller of the winding structure of the warp knitting machine, find the corresponding position for installing the crossbeam frame 1 from the wall panels at both ends of the equipment, mark and make holes, and fix the crossbeam frame 1 under the curling roller through the wall panels at both ends of the equipment.

[0052] Step 2: Install the baffle brackets 3 at both ends on the crossbeam frame 1 through screws 5 and nuts 6.

[0053] Step 3: Weld the external interfaces 401 of the flipping devices at both ends to the baffle brackets 3 at both ends.

[0054] Step 4: Weld the internal interfaces 402 of the flipping devices at both ends to the baffles 2 at both ends.

[0055] Step 5: Connect the baffle bracket 3 and the baffle 2 at both ends through the positioning pins 403.

[0056] The optimization of the unwinding operation of the material blocking device in this application includes the following steps:

[0057] Step 1: Flip the left movable baffle device 2 backward by 90° and lift it up, and place it above the curling warp beam.

[0058] Step 2: Align and lay flat the two ends of the fabric according to the marking positions of the winding roller.

[0059] Step 3: Lay the right side of the paper tube close to the right baffle 2 and press it onto the fabric.

[0060] Step 4: Insert a weighted iron rod for passive winding into the raised portion of the left baffle 2.

[0061] Step 5: Flip the left movable baffle 2 forward 90 degrees and put it down, and place it on both ends of the winding roller.

[0062] Step 6: Paste the double-sided tape on the paper tube, and press the back button of the winding roller to stick the double-sided tape on the paper tube to the fabric.

[0063] Step 7: After the paper tube and the fabric are bonded together with the double-sided tape, tighten the fabric by operating the forward button of the winding roller to achieve uniform tension on the fabric surface.

[0064] Step 8. Through the above steps, the fabric unwinding work is completed; the whole process is completed by one person, compared with the improvement before which 4 people were required to complete the operation. The device reduces the input of personnel, reduces the unwinding time, and optimizes the unwinding operation.

[0065] The optimization of the winding operation of the material blocking device in this application includes the following steps:

[0066] Step 1: After the fabric reaches the set length, apply transparent tape at the reeling position.

[0067] Step 2: Flip the movable baffles 2 on both sides backwards by 90 degrees and lift them up, and place them above the curling warp beam.

[0068] Step 3. Use the push rod on the right side to push the iron rod to the left side and out of the paper tube. Then grab one end of the iron rod from the left side and pull it out from the left side.

[0069] Step 4: After the iron rod is pulled out, the fabric is removed from the winding roller through the two ends of the paper tube.

[0070] Step 5: After the fabric is removed, it is moved after cutting.

[0071] Step 6. After the above steps, the baffle is removed by using the flip device 4 and then the fabric is moved out, thereby solving the problem of handprints caused by the weight of the iron rod and the fabric being moved by the palm of the hand, and improving the surface quality of the product.

[0072] The present application has the following advantages: the device can be used to control the fabric paper tube to be wound at a fixed position of the winding roller; the paper tube is prevented from deviating left and right on the winding roller, causing the fabric to deviate, thereby achieving the purpose of neat winding. The baffle can be turned 90° by designing a welding flipping device, thereby simplifying the phenomenon of multiple personnel and fabric shrinkage during the unwinding operation; compared with the improvement before that 4 people were required to complete the operation, the device reduces the input of personnel and reduces the time for unwinding. The baffle can be turned 90° by designing a welding flipping device, and the baffle is moved away by using the flipping device before the fabric is moved out, which solves the problem of fingerprints caused by the weight of the iron rod and the need to use the palm of the hand to move the fabric; the apparent quality of the product is improved.

[0073] In one embodiment, a multi-axial warp knitting machine is also disclosed. The multi-axial warp knitting machine includes the material blocking device of any embodiment of the present application.

[0074] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features.
