Description

Technical Field

[0001] This invention relates to a combing machine used in the pre-spinning process of textile manufacturing, and particularly to a top comb locking device suitable for a combing machine. Background Technology

[0002] In the textile industry, combing machines are used for fiber preparation during the spinning process. They are typically installed on the yarn production line between the carding machine and the drawing frame. The primary purpose of combing is to remove short fibers from the sliver produced by the carding machine, thereby increasing the length of short fibers in coarse fiber materials. Additionally, the combing operation improves the parallel orientation of individual fibers in the fiber lint extracted from the carding machine. A secondary effect of combing is the removal of neps and hulls from the fiber lint.

[0003] Generally, a textile combing machine consists of six to eight combing heads. Each combing head has a clamping device, a circular carding machine, and a pair of separating rollers. The clamping device includes an upper clamp and a lower clamp. This clamping device can fix the fiber lap fed in each time to a predetermined length. The circular carding machine combs the fiber edges of the lap, and the combed fiber web is pushed towards the pair of separating rollers by the forward movement of the clamping device. As the fiber web moves forward, the pair of separating rollers rotate in the opposite direction, moving the previously drafted fiber web backward. Therefore, the rear end of the previously combed fiber web and the front end of the just-combed fiber web overlap. When the pair of separating rollers rotates forward, the lap is pulled out from the clamping device, and the top comb inserted into the fiber web combs the fiber web. While repeating the above operation, the fiber web fed in by each combing head is bundled and drafted. The calendering rollers compress the bundled and drafted fiber web to form a combed sliver.

[0004] Typically, the top comb of a combing machine has a support. The support comprises multiple comb pins stacked linearly. The top comb at each combing station is supported on a top comb bracket located at both ends of the combing station. A single top comb fixing bracket typically secures the ends of two adjacent top combs between combing stations.

[0005] In known devices, a spring plate is provided on the top comb bracket for locking adjacent top combs supported on the top comb bracket via a fixing component. The locking and unlocking of the spring plate on the top comb is performed during maintenance operations such as disassembling the top comb for fiber roll feeding after fiber breakage, or replacing the top comb. Because the top comb bracket on the top comb bracket undergoes frequent replacement operations, mechanical stress and friction are continuously generated between the top comb bracket and the spring plate, leading to wear at both ends of the top comb bracket. This wear on the top comb bracket also affects the effective locking of the spring plate at both ends of the top comb bracket.

[0006] Furthermore, due to wear on the top comb bracket, the top comb's position on the bracket is uneven and it is locked by the spring plate. The existing spring plate cannot provide an effective and reliable locking device for the top comb, ultimately causing it to fall off / vibrate during machine operation. This, in turn, leads to severe damage to the top comb, as well as component replacement and prolonged downtime, resulting in high costs and production losses. In existing high-speed machines, the likelihood of the top comb falling off is even greater if the locking is improper. Therefore, improper locking of the spring plate on the top comb affects the overall quality of the processed fiber material and also leads to low efficiency of the textile combing machine. Therefore, it is necessary to improve the top comb locking device of the combing machine. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a top comb locking device suitable for high-speed combing machines, effectively locking the top comb. This prevents unnecessary damage to the combing machine's operating components caused by the top comb falling off, thereby overcoming the problems of machine downtime and productivity loss.

[0008] The technical solution of this invention is:

[0009] A top comb locking device for a combing machine includes a top comb bracket fixed on the combing machine, characterized in that: a top comb bracket is fixed to the top comb bracket by at least one spring plate, each spring plate includes a fixing part and a clamping part fixed to the top end of the fixing part, the clamping part of each spring plate is engaged with the upper surface of the top comb bracket, the fixing part of each spring plate is connected to the lower end of the top comb bracket, and fasteners fix the lower end of the top comb bracket and the fixing part of the spring plate connected to the lower end of the top comb bracket to the top comb bracket.

[0010] Furthermore, the fixing part of the spring plate is a rectangular plate; a clamping part is fixed to the top of the rectangular plate. The clamping part is an arc-shaped part that bends upward from the top of the fixing part and toward the top comb bracket. When the curvature of the arc is just enough to accommodate the upper end of the top comb bracket inside the clamping part, the outer surface of the upper end of the top comb bracket can be tightly fitted with the inner surface of the clamping part.

[0011] Furthermore, the clamping part of the spring plate is configured as two segments. Each of the two segments of the clamping part is the distance that the clamping part extends outward in a direction perpendicular to its central axis, with its central axis as the center. The length of each segment of the clamping part can be fixedly supported on one end of the upper end of the adjacent top combs arranged continuously on the top comb bracket.

[0012] Furthermore, the fixing part of the spring plate is provided in two sections. Each of the two sections of the fixing part is the distance that the fixing part extends outward in a direction perpendicular to its central axis, with its central axis as the center. The length of each section of the fixing part can be fixedly supported on one end of the lower end of the adjacent top comb brackets arranged continuously on the top comb bracket.

[0013] Furthermore, the top of the clamping part of the spring plate is fixedly connected to an "S"-shaped second clamping part. The second clamping part is bent with its top surface facing upward and away from the direction of the top comb bracket, forming a bent part. Then, it extends obliquely upward along the direction away from the top comb bracket to form a pressing part. The end face of the pressing part does not exceed the highest point of the arc of the clamping part. The top surface of the pressing part away from the top comb bracket extends obliquely upward and toward the direction of the top comb bracket to form an inclined vertical plate.

[0014] Furthermore, the second clamping part of the spring plate is provided as two segments. Each of the two segments of the second clamping part is the distance that the second clamping part extends outward in a direction perpendicular to its central axis, with its central axis as the center. The length of each segment of the second clamping part can be fixedly supported on one end of the upper end of the adjacent top combs arranged continuously on the top comb bracket.

[0015] Furthermore, the clamping part of the spring plate has a smaller flexibility or bending stiffness, while the fixing part of the spring plate has a larger flexibility or bending stiffness, and the flexibility and stiffness of the clamping part are both smaller than those of the fixing part.

[0016] Furthermore, the clamping portion of the spring plate has a through hole along its central axis.

[0017] Furthermore, the fastener is a concave baffle, and the length of the concave portion in the middle of the concave baffle is greater than the length of the fixing portion of the spring plate, and the lower end of the concave baffle is provided with a fastener fixing hole.

[0018] Furthermore, the fastener has a fastener side stop on both sides along its length direction.

[0019] Furthermore, the top comb bracket includes a bracket fixing rod and a bracket docking block on the side top surface of the bracket fixing rod facing the fastener. The lower end of the bracket docking block is provided with a bracket fixing hole. The middle part of the side of the bracket docking block facing the fastener is provided with an inner groove along its length direction. Both sides of the bracket docking block along its length direction are provided with an inner recessed bracket slot. The lower end of the top comb bracket is engaged in the bracket slot. The connecting locking member passes through the fastener fixing hole in sequence and stops at the bracket fixing hole, thereby fixing the lower end of the top comb bracket and the spring plate fixing part connected to the lower end of the top comb bracket to the top comb bracket.

[0020] Furthermore, the bottom end of the fixing part of the spring plate is provided with a bracket connecting strip. The bracket connecting strip is a columnar body that extends along the length direction of the bottom end of the fixing part. The bracket connecting strip is rotatably placed in the inner groove.

[0021] The beneficial technical effects of this invention are as follows: This invention provides a top comb locking device, which includes a top comb bracket fixed on a combing machine, a spring plate fixing a top comb support to the top comb bracket, and a top comb fixed to the top comb bracket. The spring plate includes a fixing part, a clamping part, and a second clamping part. The fixing part fixes the lower end of the top comb bracket to the top comb bracket, the clamping part engages with the upper end of the top comb bracket, and the second clamping part further applies downward pressure to the upper end of the top comb bracket, thereby achieving effective locking of the top comb bracket and the top comb.

[0022] Furthermore, since the clamping part of the present invention has a small degree of flexibility or bending stiffness, the upper end of the top comb bracket can be firmly locked in the clamping part to prevent it from loosening; the fixing part has a large degree of flexibility or bending stiffness. Since the fixing part is fixed to the lower end of the top comb bracket and the top comb is fixed to the top comb mounting part, the top comb will cause the top comb bracket to vibrate to a certain extent during high-speed operation. The fixing part is configured to have a large degree of flexibility or bending stiffness so that the connection between the fixing part and the top comb mounting part of the top comb bracket has a certain degree of elasticity, which is more stable than the rigid connection between the two.

[0023] In addition, the clamping part of the spring plate of the present invention has a through hole structure to improve the stress distribution of the clamping part, so as to counteract the vibration force generated on the spring plate by the top comb support due to the high-speed movement of the top comb, making the connection between the top comb support and the spring plate more stable when the combing machine is running at high speed, avoiding unnecessary damage to the running parts of the combing machine due to the top comb falling off, and thus overcoming the problems of machine downtime and productivity loss.

[0024] Furthermore, since the bottom end of the fixing part of the spring plate of the present invention is also provided with a bracket connecting strip, and the bracket connecting strip is rotatably placed in the inner groove of the top comb bracket, when the top comb bracket or the top comb fixed to the top comb bracket needs to be replaced due to wear, the spring plate can be pulled away from the top comb bracket to unlock the top comb bracket, thereby facilitating the replacement of a new top comb bracket or top comb, without the need to frequently unlock the top comb bracket fixed to the combing machine, thus simplifying the replacement steps and improving production efficiency.

[0033] In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] This invention provides a top comb locking device suitable for a combing machine, which is applied to a combing machine. For example... Figure 1 As shown, the fiber filament 1 in the comber 1a is fed to a circular carding machine 2 rotating around an axis. During the combing process, the fiber filament 1 is fed in by the feed roller 3 and fixed by a set of clamps (upper clamp 4, lower clamp 5). After the combing cycle, the combed fiber clusters merge with the previously combed fibers and are simultaneously pulled between the separating rollers 8 by engaging a top comb 6 in one of the fiber clusters. At the same time, the separating rollers 8 pull the combed fibers out from the feed roller 3 and the combed fiber area. In this process, the desired improvements can be made to remove short fibers and to parallelize individual fibers in the fiber filament. Typically, the top comb 6 is mounted on a top comb support 7.

[0035] Example 1

[0036] The present invention discloses a top comb locking device suitable for a combing machine, which includes a top comb bracket 10 fixed on the combing machine 1a, a top comb support 7 fixed to the top comb bracket 10 by at least one spring plate 9, a fastener 11 fixing the spring plate 9 and the top comb support connected to the spring plate 9 to the top comb bracket 10 by a connecting locking member, and a top comb 6 detachably installed on the top comb support 7.

[0037] like Figure 6As shown, the top comb bracket 10 of the present invention includes a bracket fixing rod 14 and a bracket fixing rod 17 with a bracket docking block 13 on the side top surface facing the fastener 11. The bracket fixing rod 14 is fixed to the combing machine 1a; the lower end of the bracket docking block 13 is provided with a bracket fixing hole, the middle part of the bracket docking block 13 is provided with an inner groove 15 along its length direction, and both sides of the bracket docking block 13 along its length direction are provided with a bracket slot 16 that is recessed into its central axis, and the lower end of the top comb bracket 7 is engaged in the bracket slot 16.

[0038] like Figure 6 As shown, the fastener 11 of the present invention is a concave baffle, and the length of the concave portion in the middle of the concave baffle is greater than the length of the fixing portion of the spring plate. The lower end of the concave baffle is provided with a fastener fixing hole; a fastener side guard 12 is provided on both sides along the length direction of the fastener 11. In this example 1, each fastener side guard 12 is cylindrical. When the present invention is assembled and put into practical use, the connecting locking member passes through the fastener fixing hole in sequence and stops at the bracket fixing hole, thereby fixing the lower end of the top comb bracket 7 and the fixing portion of the spring plate 9 connected to the lower end of the top comb bracket 7 to the top comb bracket 10; at this time, the outer surfaces of both sides of the top comb bracket 10 along the length direction just abut against the inner surfaces of the corresponding two fastener side guards 12, thereby further strengthening the connection with the top comb bracket 10. Among them, the connecting locking member used in the present invention is a screw.

[0039] In this embodiment 1, the top comb bracket 7 includes a top comb mounting part 18 and a bracket support part 19. The top comb mounting part 18 is a rectangular strip with an inverted V-shaped notch at one end of its bottom edge. The opening of the inverted V-shaped notch faces the top comb 6. The inverted V-shaped notch divides the top comb mounting part into a long side and a short side. The top comb 6 is fixed to the vertical side of the long side of the inverted V-shaped notch of the top comb mounting part and faces the top comb bracket 10. The short side of the top comb mounting part 18 is vertically inserted into the bracket slot 15 on one side of the bracket connecting block 13. The top of the top comb mounting part 18 is bent upward and towards the top comb bracket 10 to form an arc-shaped bracket support part 19. When the short side of the top comb mounting part is inserted into the bracket slot 15 on one side of the bracket connecting block 13, the bottom end of the bracket support part 19 just abuts against the top surface of the bracket connecting block 13, thereby initially fixing the top comb bracket 7 to the top comb bracket 10.

[0040] like Figure 2 and 3As shown, in this embodiment 1, the spring plate 9 includes a fixing part 92 and a clamping part 91 integrally formed at the top of the fixing part 92. The fixing part 92 of the spring plate 9 is a rectangular plate; the clamping part 91 is fixedly attached to the top surface of the rectangular plate, and the clamping part 91 is an arc-shaped part that bends upward from the top of the fixing part 92 and toward the top comb bracket 7. In addition, a bracket connecting strip 17 is provided at the bottom end of the fixing part 92 of the spring plate 9, and the bracket connecting strip 17 is a columnar body that extends along the length direction of the bottom end of the fixing part 92.

[0041] The bracket connecting strip 17 is placed in the bracket slot 15 on the top comb bracket 10. At this time, the fixing part 92 of the spring plate 9 is placed on the side surface of the bracket docking block 13 of the top comb bracket 10 facing the fastener 11.

[0042] When the fastener fixing hole at the lower end of the fastener 11 corresponds to the bracket fixing hole at the lower end of the top comb bracket, both sides of the fastener 11 along its length direction exactly cover both ends of the inner groove 15, thus sealing the bracket connecting strip 17 within the inner groove 15. At this time, the fixing part 92 of the spring plate 9 is located in the middle recess of the fastener 11. The screw passes through the fastener fixing hole in sequence and stops at the bracket fixing hole, thereby initially fixing the top comb bracket 7 onto the top comb bracket 10. At the same time, the clamping part 91 of the spring plate 9 engages with the surface of the bracket support part 19 of the top comb bracket 7, and when the curvature of the clamping part 91 is just enough to allow the bracket support part to engage within it, the outer surface of the bracket support part of the top comb bracket 7 can fit tightly with the inner surface of the clamping part 91, thereby finally locking the top comb bracket 7 onto the top comb bracket 10 using the spring plate.

[0043] Furthermore, the clamping portion 91 of the spring plate 9 is integrally formed with an S-shaped second clamping portion 93. The second clamping portion 93 is formed by bending the top surface of the clamping portion 91 upwards and away from the direction of the top comb bracket 7, forming a bent portion, and then extending obliquely upwards along the direction away from the top comb bracket 7 to form a pressing portion. The terminal surface of the pressing portion does not exceed the highest point of the arc of the clamping portion 91. The pressing portion extends obliquely upwards away from the top surface of the top comb bracket 7 and toward the direction of the top comb bracket 7 to form an inclined vertical plate. The pressing portion of the second clamping portion 93 abuts precisely against the arc segment from the highest point to the lowest point of the arc of the support portion of the top comb bracket 7, thereby forming an oblique downward pressing force on the support portion of the top comb bracket 7, thereby further strengthening the clamping and locking force of the spring plate 9 on the top comb bracket 7.

[0044] In addition, the clamping part 91 has a small degree of flexibility or bending stiffness, which allows the support part of the top comb bracket 7 to be firmly locked in the clamping part 91 and prevents it from loosening; the fixing part 92 has a large degree of flexibility or bending stiffness. Since the fixing part 92 is fixed to the top comb mounting part of the top comb bracket 7, and the top comb 6 is fixed to the top comb mounting part, the top comb 6 will cause the top comb mounting part to vibrate to a certain extent during high-speed operation. The fixing part 92 is configured to have a large degree of flexibility or bending stiffness so that the connection between the fixing part 92 and the top comb mounting part of the top comb bracket 7 has a certain degree of elasticity, which is more stable than the rigid connection between the two.

[0045] In addition, a through hole can be opened in the clamping part 91 of the spring plate along its central axis to improve the stress distribution of the clamping part 91, so as to counteract the vibration force generated on the spring plate by the top comb support 7 due to the high-speed movement of the top comb 6, and make the connection between the top comb support 7 and the spring plate more stable when the combing machine is running at high speed.

[0046] When the top comb bracket 7 is worn and needs to be replaced, simply pull the spring plate away from the top comb bracket 10. The bracket connecting strip 17 on the spring plate will rotate away from the top comb bracket in the inner groove 15 under force, thereby unlocking the top comb bracket. This makes it easy to replace the top comb bracket or top comb with a new one, without having to frequently unlock the top comb bracket that is fixed to the combing machine. This simplifies the replacement process and improves production efficiency.

[0047] Example 2

[0048] Compared with Embodiment 1, the only difference in Embodiment 2 is the structure of the clamping part in the spring plate 9; the structures and connections of the other components are the same, and will not be described again here. In Embodiment 2, the spring plate 9 includes a fixing part 9b, a clamping part 9a, a second clamping part 9c, and a bracket connecting strip 17a. The structure of the fixing part 9b and the bracket connecting strip 17a of the spring plate 9 are the same as the structure of the fixing component 92 of the spring plate 9 in Embodiment 1, and will not be described again here.

[0049] like Figure 3 As shown, in practical applications, a single top comb bracket 7 is usually fixed between two adjacent top comb ends between the workstations of the combing machine 1a. This allows the two adjacent top comb brackets 7 to be fixed on the same top comb bracket 10, thereby reducing the number of parts and saving production costs.

[0050] The short sides of the inverted V-shaped notch of the top comb mounting part of the two adjacent top comb brackets 7 are vertically inserted into the bracket slots 15 on one side of the bracket connecting block 13. At this time, the bottom end of the bracket support part 19 of the two adjacent top comb brackets 7 is exactly abutting against the top surface of the bracket connecting block 13, thereby realizing the simultaneous initial fixation of the two adjacent top comb brackets 7 on the top comb bracket 10.

[0051] When the fastener fixing hole at the lower end of the fastener 11 corresponds to the bracket fixing hole at the lower end of the top comb bracket, both sides of the fastener 11 along its length direction exactly cover both ends of the inner groove 15, that is, the bracket connecting strip 17a is exactly sealed in the inner groove 15. At this time, the fixing part 9b of the spring plate 9 is located in the middle recess of the fastener 11. The screws pass through the fastener fixing holes in sequence and stop at the bracket fixing holes, thereby initially fixing the two adjacent top comb brackets 7 to the top comb bracket 10.

[0052] like Figure 4 As shown, a clamping part 9a is integrally formed at the top of the fixing part 9b. This clamping part 9a has the same structure as the clamping part 91 in Embodiment 1, except that the clamping part 9a is divided into two segments. Each end of the clamping part 9a extends a distance perpendicular to its central axis. The length of each segment of the clamping part 9a can be fixed to one end of the support portion of two adjacent top comb brackets 7 arranged continuously on the top comb bracket 10. The support portions of the two adjacent top comb brackets 7 are simultaneously engaged in the clamping part 9a, and the support portions of each adjacent top comb bracket 7 are located exactly within each segment of the clamping part 9a. This achieves the final locking of two adjacent top comb brackets 7 onto the same top comb bracket 10 using the same spring plate 9.

[0053] Furthermore, in this embodiment 2, the top of the clamping part 9a is integrally formed with an S-shaped second clamping part 9c. The structure of the second clamping part 9c is the same as that of the second clamping part 93 in embodiment 1. The difference is that the second clamping part 9c is set as two segments. Each of the two segments of the second clamping part, that is, the second clamping part 9c extends a distance perpendicular to its central axis. The length of each segment of the second clamping part 9c can be fixedly supported on one end of the bracket support of the adjacent top comb brackets 7 arranged continuously on the top comb bracket 10. That is, each segment of the downward pressing part of the second clamping part 9c just abuts against one end of the bracket support of the two adjacent top comb brackets 7 on the same side as the short side of its top comb mounting part. This forms a downward clamping force on the bracket support of the two adjacent top comb brackets 7, thereby further strengthening the clamping and locking force of the spring plate 9 on the two adjacent top comb brackets 7.

[0054] Example 3

[0055] Compared with Example 2, in Example 3, the clamping part 9d, the second clamping part 9f, and the bracket connecting bar 17b of the spring plate 9 are the same as the clamping part 92, the second clamping part 93, and the bracket connecting bar 17b in Example 2. The structures and connections of the remaining components are also the same, except that the structure of the fixing part 9e in the spring plate 9 is different.

[0056] like Figure 5 As shown, in this embodiment 3, the fixing part 9e of the spring plate 9 is also a rectangular plate. Compared with embodiment 2, the difference is that the fixing part 9e is set as two segments. Each of the two segments of the fixing part 9e is the distance that the fixing part 9e extends in a direction perpendicular to its central axis. That is, the length of the fixing part 9e in embodiment 3 is greater than the length of the fixing part 9b in embodiment 2. Compared with embodiment 2, the structure and function of the clamping part 9d and the second clamping part 9f of the spring plate 9 are the same as those of the clamping part and the second clamping part of the spring plate 9 in embodiment 2. The fixing part 9e of the spring plate 9 is set as two segments, which increases the contact area between the fixing part 9e and the bracket docking block 13 on the top comb bracket, thereby strengthening the connection between the spring plate 9, the short side of the top comb mounting part of the two adjacent top comb brackets 7 and the same top comb bracket 10.

[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
