Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing, in particular to a tubular cloth whole material component and a conveyor. Background Art

[0002] The tubular fabrics used in clothing processing are often whole pieces of a certain length. During the clothing processing process, the tubular fabrics, such as wool textiles, need to be cut into sections according to a certain length, and then the sectioned fabrics are made into finished products such as hats and scarves.

[0003] During the garment processing stage, after receiving the entire roll of tubular fabric, an automatic cutting machine automatically cuts it into a set length. The cutting process can be automated, but during the production process, the tubular fabric often twists at a certain point within a certain length range. During the cutting process of the finished product, the size of each segment cannot be accurately controlled, and the cut parts may be uneven and not meet the requirements, resulting in fabric waste. In severe cases, it may even damage the cutting knife.

[0004] Currently, manual smoothing is usually adopted before entering the automatic conveying and cutting process, which requires an operator to be on duty, resulting in high labor costs. Utility Model Content

The steering roller assembly is used to guide the cloth passing through the whole material assembly and change the conveying direction of the cloth so that the cross-section of the cloth is in a straight line and enters between the conveyor and the first pressure roller assembly.

[0027] A guide roller assembly is provided between the steering roller assembly and the feed end of the conveyor.

[0054] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0055] Example 1:

[0056] like Figure 1-Figure 5 As shown, the tubular cloth whole material assembly of this embodiment, the whole material assembly 2 is arranged on the feeding end side of the conveyor 7 of the cloth 9, and the structure of the whole material assembly 2 includes a fixing frame 23, an internal guide cylinder 24, an external limit member 22 and an internal straight guide member 21.

[0057] The fixed frame 23 is fixedly mounted relative to the frame 8 of the conveyor 7, and can be specifically mounted on the frame 8;

[0058] An inner guide cylinder 24, the outer wall of which matches the inner cylinder size of the cloth 9, is used to stretch the cloth 9 so that the cloth 9 is cylindrical, and the central axis of the inner guide cylinder 24 is arranged in the vertical direction;

[0059] The external limiting member 22 is provided on the fixing frame 23 and limits the internal guide cylinder 24 in the horizontal and vertical directions from the outer periphery of the internal guide cylinder 24. A gap is provided between the external limiting member 22 and the internal guide cylinder 24 for passing the cloth 9.

[0060] The inner straight guide member 21 is disposed above the inner guide cylinder 24 and is used to open the cloth 9 from the inside of the cloth 9 so that the cross section of the cloth 9 is flat.

[0061] The cloth 9 is cylindrical and has a certain length, and can continuously convey the cut and segmented materials. The cylindrical cross-section direction of the cloth 9 has a certain elasticity, such as a wool fabric. Figure 5 The dotted line indicates the conveying direction and position of the cloth 9.

[0062] An internal guide cylinder 24 is provided in the external limiting member 22 on the fixing frame 23. The external limiting member 22 supports and limits the internal guide cylinder 24 while maintaining a gap between the external limiting member 22 and the internal guide cylinder 24, so that the cloth 9 can be sleeved on the outside of the internal guide cylinder 24 and transported upward, guiding the cloth 9 to be stretched into a cylindrical shape, so that the naturally drooping cloth 9 is straightened after passing through the internal guide cylinder 24, and then after passing through the straight guide member 21, the cloth 9 is stretched into a flat shape, so that the cross section of the cloth 9 is straight and enters the feed end of the conveyor 7, which is convenient for subsequent stable transportation, and can accurately cut the cylindrical cloth, reduce labor costs, and improve material utilization and the service life of the cutting equipment.

[0063] Specifically, during the process of conveying the cloth 9 to the conveyor 7, the first pressure roller assembly 3 and the conveyor 7 provide pulling force, the external limit member 22 limits the internal guide cylinder 24, and the combined effect of the gravity of the internal guide cylinder 24 on the sliding cloth 9 provides tension during the conveying process of the cloth 9, thereby ensuring the stability of the I-shaped cross-section of the cloth 9.

[0064] like Figure 2 、 Figure 4 As shown, the structure of the internal guide cylinder 24 is as follows: it includes an expanded section 242, the outer wall surface of the expanded section 242 is a cylindrical surface, and the diameter of the cylindrical surface is larger than the diameter of the cloth 9 in its natural state; it also includes a lower guide cone 243 located at the lower end of the expanded section 242, and an upper guide cone 241 located at the upper end of the expanded section 242; the lower guide cone 243 is an inverted cone surface, which is used to guide the cloth 9, so that the twisted cloth 9 is reversely twisted to a straightened state, and the upper guide cone 241 is used to shrink the cloth 9 to its natural state before passing through the straight guide member 21.

[0065] The diameter of the cylindrical surface on the expansion section 242 is 1.1 to 1.2 times the diameter of the cloth 9 in its natural state. The lower end diameter of the lower guide conical surface 243 is less than or equal to the diameter of the cloth 9 in its natural state, and the upper end diameter of the upper guide conical surface 241 is less than or equal to the diameter of the cloth 9 in its natural state.

[0066] like Figure 1-Figure 4 As shown, there are multiple external limit members 22, specifically greater than or equal to three. The external limit members 22 are evenly distributed in an array around the central axis of the internal guide cylinder 24. The structure of each external limit member 22 is as follows: including a bracket 222 connected to the fixing frame 23; a lower roller 224 is provided at the lower end of the bracket 222 to cooperate with the lower end of the internal guide cylinder 24. The multiple lower rollers 224 support the internal guide cylinder 24 from the outer periphery of the lower end of the internal guide cylinder 24, and the above-mentioned gap is formed between the lower rollers 224 and the internal guide cylinder 24.

[0067] The upper end of the bracket 222 is provided with an upper roller 221 that cooperates with the upper end of the internal guide cylinder 24. Multiple upper rollers 221 limit the vertical height of the internal guide cylinder 24 from the outer periphery of the upper end of the internal guide cylinder 24, and there is the above-mentioned gap between the upper roller 221 and the internal guide cylinder 24.

[0068] The above gap means that when the cloth 9 passes outside the inner guide cylinder 24, the thickness of the cloth 9 is filled between the outer limiter 22 and the inner guide cylinder 24, but when there is no cloth 9, the inner guide cylinder 24 contacts the lower roller 224 under the action of gravity.

[0069] like Figure 2 As shown, in the above structure of the external limit member 22, the lower roller 224 cooperates with the lower guide cone surface 243 on the internal guide cylinder 24, and the upper roller 221 cooperates with the upper guide cone surface 241 on the internal guide cylinder 24, so that the external limit member 22 limits the internal guide cylinder 24 horizontally and vertically from the outer periphery of the internal guide cylinder 24.

[0070] Preferably, the diameter of the cross-section of the lower roller 224 corresponding to the support point of the inner guide cylinder 24 is larger than the diameter of the cloth 9 in its natural state, and the support point is located on the lower guide cone 243. When the lower guide cone 243 and the cloth 9 move relative to each other, the lower guide cone 243 guides and expands the cloth from the inside of the cloth 9 until it is larger than the diameter of the cloth 9 in its natural state. In this process, the naturally sagging cloth 9 is straightened out. The lower roller 224 assists the cloth 9 in sliding upward, and simultaneously positions the cloth 9 relative to the inner guide cylinder 24 from multiple points outside the cylindrical cross-section of the cloth 9, ensuring the consistency of the grain direction of the cloth 9 passing through the expanded section 242.

[0071] In another embodiment, in order to facilitate the disassembly and installation of the external limiting member 22 and the internal guide cylinder 24, as well as the adjustment of the gap, the installation structure of the external limiting member 22 is further optimized. Figure 2-Figure 4 As shown, each external limit member 22 also includes a screw 223 threadedly connected to the fixing frame 23, the end of the screw 223 is detachably connected to the bracket 222, and also includes a guide rod 225, one end of the guide rod 225 is threadedly connected to the bracket 222, and the other end of the guide rod 225 is slidably connected to the fixing frame 23.

[0072] There are two guide rods 225 , which are located at the upper and lower sides of the screw rod 223 respectively.

[0073] like Figure 3 As shown, the detachable connection structure between the end of the screw rod 223 and the bracket 222 includes a slot 2220 provided on the bracket 222, and a clamping head 2230 provided at the end of the screw rod 223. The length direction of the slot 2220 is horizontal and both ends pass through the bracket 222. The cross section of the slot 2220 is T-shaped. The clamping head 2230 is a circular boss structure that cooperates with the slot 2220. After the clamping head 2230 slides from one end of the slot 2220 into the bottom of the slot 2220 and the guide rod 225 is installed in place, the screw rod 223 is detachably connected to the bracket 222. By adjusting the position of the screw rod 223 relative to the fixing frame 23, the distance between the bracket 222 and the internal guide cylinder 24 can be adjusted, thereby adjusting the above-mentioned gap. By adjusting the relative position of each bracket 222, the horizontal position of the internal guide cylinder 24 can be adjusted.

[0074] like Figure 2 As shown, the structure of the straight guide member 21 is as follows: it includes symmetrically arranged support rods 212, one end of which is fixedly connected to the internal guide cylinder 24, and the other end of the support rod 212 is located at the upper end of the internal guide cylinder 24 and is provided with a guide head 211. The two guide heads 211 expand the cloth 9 from the inside, making the cross-section of the cloth 9 flat. The guide head 211 can be a roller rotatably mounted on the upper end of the support rod 212.

[0075] When the cloth 9 with a flat cross section directly enters between the conveyor 7 and the first pressure roller assembly 3 , the plane where the center planes of the two support rods 212 lie is coplanar with the vertical tangent plane of the conveying surface at the active roller 71 .

[0076] A hole adjustment block 213 is detachably installed in the internal guide cylinder 24. A plurality of mounting holes are provided on the hole adjustment block 213. The support rods 212 are detachably connected to the mounting holes. By selecting different mounting holes, the distance between the two support rods 212 can be adjusted, thereby adjusting the degree to which the fabric 9 is stretched.

[0077] Example 2:

[0078] In the cylindrical cloth conveyor of this embodiment, the cylindrical cloth whole-material assembly 2 of any embodiment is installed on the frame 8 of the conveyor 7, and a first pressure roller assembly 3 is provided above the feed end of the conveyor 7. The first pressure roller assembly 3 cooperates with the conveying mechanism 7 to provide conveying power, and the cross-section of the cloth 9 entering between the conveying mechanism 7 and the first pressure roller assembly 3 is in the shape of a straight line.

[0079] The whole material assembly 2 is stretched out from the inside of the cylindrical cloth 9, twisting the twisted cloth 9 in the reverse direction to a straightened state, so that the cross-section of the cloth 9 is in a straight line shape and enters between the conveyor 7 and the first pressure roller assembly 3, ensuring that the cutting part of the automatic cutting mechanism 5 downstream of the conveyor 7 is flush.

[0080] like Figure 5 、 Figure 6 As shown, the structure of the conveyor 7 includes a motor 73 mounted on a frame 8, and a driving roller 71 and a driven roller 74 rotatably mounted on the frame 8, and also includes a belt 72, which is sleeved outside the driving roller 71 and the driven roller 74 and is in a tensioned state. The driving roller 71 is located at the feed end of the conveyor 7, and the driven roller 74 is located at the discharge end of the conveyor 7;

[0081] The first pressing roller assembly 3 includes a fixed roller 34 rotatably mounted above the active roller 71 , and cooperates with the belt 72 to apply tension to the cloth 9 .

[0082] like Figure 5 、 Figure 6 As shown, the structure of the first pressure roller assembly 3 includes a first shaft seat 33 and a first guide shaft 32 fixedly mounted on the frame 8. The first shaft seat 33 is slidably connected to the first guide shaft 32. A fixed roller 34 is rotatably mounted on the first shaft seat 33. The fixed roller 34 is located above the feed end of the conveyor 7 and corresponds to the active roller 71. It also includes a fixed rod 31. One end of the fixed rod 31 is connected to the first shaft seat 33, and the other end of the fixed rod 31 is connected to the upper end of the first guide shaft 32. The fixed rod 31 is used to adjust the distance between the fixed roller 34 and the conveying surface of the conveyor 7 to a suitable position and fix it.

[0083] The first pressure roller assembly 3 presses the cloth 9 downward toward the conveying surface of the conveyor 7, and the fixed roller 34 rolls as the conveying surface of the conveyor 7 moves backward. The first pressure roller assembly 3 and the conveying surface of the conveyor 7 simultaneously apply friction force from the upper and lower planes of the cloth 9, thereby applying tension to the cloth 9, so that the cloth 9 can smoothly pass through the whole material assembly 2 into between the conveyor 7 and the first pressure roller assembly 3, and continue to be conveyed downward to the automatic cutting mechanism 5.

[0084] like Figure 5As shown, the automatic cutting mechanism 5 includes a mobile frame 51 slidably mounted on the frame 8, a cutting knife 52 is mounted on the mobile frame 51, and a cylinder 53 is fixedly mounted on the frame 8. The output end of the cylinder 53 is transmission-connected to the mobile frame 51 to drive the mobile frame 51 to rise and fall, thereby realizing the automatic cutting function.

[0085] By arranging the material assembly 2 on one side of the feeding end of the conveyor 7, the cloth 9 is guided and stretched so that the cross section of the cloth 9 is in a straight line shape when entering the subsequent conveying and cutting process, thereby preventing the cloth 9 from entering the cutting process in a twisted state.

[0086] like Figure 5 、 Figure 6 The conveyor 7 also includes a steering roller assembly 1, which is located above the feed end of the conveyor 7 and above the whole material assembly 2. The steering roller assembly 1 is used to guide the cloth 9 passing through the whole material assembly 2 and change the conveying direction of the cloth 9 so that the cross-section of the cloth 9 is in a straight line and enters between the conveyor 7 and the first pressure roller assembly 3.

[0087] A specific implementation method, such as Figure 5 As shown, the deflection roller assembly 1 is located between the monolith assembly 2 and the guide roller assembly 4 .

[0088] Exemplarily, the structure of the steering roller assembly 1 includes a steering roller base 12 fixedly connected to the frame 8, and a steering roller shaft 11 is rotatably mounted on the steering roller base 12. The vertical section of the steering roller shaft 11 is coplanar with the plane where the center planes of the two support rods 212 are located. The number of steering roller shafts 11 can be two, which are arranged side by side in the horizontal direction.

[0089] The cloth 9 is conveyed upward through the material assembly 2, enters the steering roller assembly 1, and is then conveyed downward to the feed end of the conveyor 7, so that there is a longitudinal space between the material assembly 2 and the conveyor 7, so that the cloth 9, which has become flat in a state with a certain tension, is fully straightened into a straight line within a conveying space, avoiding swinging of the cloth 9 during the conveying process, facilitating stable conveying of the conveyor 7 process and ensuring cutting accuracy.

[0090] The distance between the two struts 212 allows the cloth 9 to be stretched to a natural state or degree with a certain tensile deformation (the width of the straight line is slightly larger than the natural width). It is preferred to have a certain tensile deformation so that the straight line state of the cloth 9 is more stable when it enters the conveyor 7.

[0091] like Figure 5 、 Figure 6As shown, a guide roller assembly 4 is provided between the steering roller assembly 1 and the feed end of the conveyor 7. The structure of the guide roller assembly 4 includes a guide roller base 41 fixedly mounted on the frame 8 of the conveyor 7, a guide roller shaft 42 is rotatably mounted on the guide roller base 41, and a first limit block 43 and a second limit block 44 are axially spaced apart on the guide roller shaft 42. The first limit block 43 and the second limit block 44 are used to guide and limit the cloth 9 with a straight line shape in cross section.

[0092] The steering roller assembly 1 further straightens the cloth 9 before the feeding end of the conveyor 7 and provides a limiting structure to prevent the cloth 9 from deviating before entering the conveyor 7, thereby ensuring cutting accuracy.

[0093] Example 3:

[0094] During the conveying and cutting process, the tail end of the entire cloth 9 may be insufficient in length. Manual detection is usually used to remove the insufficient length material segment, and the waste material cannot be collected quickly and in time.

[0095] Based on the above embodiments, Figure 5-Figure 7 As shown, in this embodiment, the automatic cutting mechanism 5 for cutting the cloth 9 is arranged at the discharge end of the conveyor 7; the conveyor 7 of this embodiment also includes a second pressure roller assembly 6, the structure of the second pressure roller assembly 6 includes a movable roller 63 and a second shaft seat 62 located above the discharge end of the conveyor 7, the movable roller 63 is rotatably mounted on the second shaft seat 62, a second guide shaft 61 is fixedly mounted on the frame 8, the second shaft seat 62 is slidably mounted on the second guide shaft 61, the movable roller 63 is located above the cloth 9 and is supported by the cloth 9, and also includes a sensor 64 for detecting the height of the second shaft seat 62.

[0096] The movable roller 63 can be lifted and lowered vertically along the second guide shaft 61 under the action of external force. The sensor 64 is installed on the frame 8 and can be a distance sensor for detecting the height position of the second shaft seat 62. The sensor 64 is triggered when the movable roller 63 falls directly on the conveying surface of the conveyor 7. At this time, the material section conveyed to the downstream of the conveyor 7 is waste.

[0097] A freely rising and falling movable roller 63 is provided above the cloth 9 at the discharge end of the conveyor 7, so that the cloth 9 is lifted up when passing through the movable roller 63 and the conveyor 7. Since the cutting length is related to the step-by-step conveying time interval of the conveyor 7, when the movable roller 63 falls due to the absence of cloth 9 underneath within a step-by-step conveying time interval, the sensor 64 can remind that the cut material section is waste. The detection mechanism has a simple structure and timely and sensitive feedback.

[0098] The working process of the tubular cloth conveyor of this embodiment is as follows:

[0099] The cloth 9 is guided and stretched into a cylindrical shape from the inside by the material assembly 2, and the cloth 9 is conveyed from bottom to top, so that the cloth 9 in a twisted state at the lower end of the material assembly 2 is reversely twisted to a straightened state;

[0100] After the straightened cloth 9 passes through the upper end of the straightening assembly 2, the cloth 9 is stretched out and changes from a cylindrical shape to a flat shape;

[0101] The flat cloth 9 is conveyed to the automatic cutting mechanism 5 downstream of the conveyor 7 under the pulling force of the feeding end of the conveyor 7 and is cut;

[0102] The movable roller 63 located above the discharge port of the conveyor 7 is freely pressed down on the cloth 9 and rotates freely as the cloth 9 is conveyed. When the automatic cutting mechanism 5 completes the cutting action and detects that the distance between the movable roller 63 and the conveying surface of the conveyor 7 is less than the set value, it is judged that the currently cut material segment is waste, and the downstream conveyor line is prompted to transfer the waste to the waste area.

[0103] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
