Description

Technical Field

[0001] This invention belongs to the technical field of combing machine equipment, specifically relating to a novel top comb frame device for a combing machine. Background Technology

[0002] The top comb holder used in a combing machine is generally a long, strip-shaped component, with the top comb mounted on it. The top comb holder is typically mounted on top comb support feet via mounting points at both ends and is secured by clamping components such as top comb pressure plates and springs. In existing technology, the top comb holder is generally made of lightweight materials such as aluminum alloy, forming a one-piece structure where the main body of the top comb holder and the clamping areas at both ends are integrally molded and cannot be separated.

[0003] During the high-speed operation of the combing machine, the top comb frame is subjected to varying dynamic loads. In existing integrated top comb frames, the compression springs are directly pressed against the aluminum alloy bodies at both ends of the top comb frame. Since the hardness of aluminum alloy is lower than that of compression springs made of spring steel, and the top comb frame exhibits elastic deformation in the longitudinal direction, this elastic deformation causes micro-friction between the clamping areas at both ends of the top comb frame and the top comb support feet and compression springs. As the usage time increases, the two ends of the top comb frame gradually wear down, leading to a decrease in the installation stability of the top comb frame and inaccurate installation position, which in turn affects the quality of the combed cotton sliver.

[0004] To address the aforementioned wear problem, some improvements have been made in the existing technology. For example, some solutions include installing wear-resistant blocks at both ends of the top comb frame mounting base to improve the wear resistance of the mounting surface; others involve installing additional retaining devices made of higher hardness materials on the retaining part of the top comb frame to reduce wear. However, these solutions only delay the occurrence of wear to a certain extent and do not change the fundamental nature of the top comb frame being difficult to repair after wear at both ends. Since the top comb frame is an integral structure, when the clamping areas at both ends wear to a certain extent, the entire top comb frame often needs to be scrapped and replaced. This not only increases the cost of spare parts but also reduces the effective operating time of the equipment. Summary of the Invention

[0005] In view of this, the present invention provides a novel top comb frame device for a combing machine, which aims to replace the integrated clamping structure at both ends of the traditional top comb frame body with detachable and replaceable nylon left and right ends. The connection stability is improved by installing protrusions and cavities with interference fit, screw fixing and compression spring clamping structure. This solves the problems of wear at both ends of the existing top comb frame body due to dynamic load and fretting friction, the need for overall replacement after wear, and the easy displacement of the installation position. It achieves the effects of reducing maintenance and spare parts costs, extending the service life of the top comb frame body, improving installation stability and combed cotton sliver quality.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows.

[0007] A novel top comb holder device for a combing machine includes:

[0008] There are two top comb feet. The top comb feet are composed of an integrally formed connecting part and a mounting part. The top comb feet are set on the combing machine through the connecting part. The mounting part has a foot groove on its circumferential side wall.

[0009] The main body of the top comb frame is a long strip-shaped component. Both ends of the main body of the top comb frame are provided with a first cavity and a second cavity, and each first cavity is provided with an internal thread.

[0010] The left end and the right end are located at the two ends of the top comb frame body, respectively, and the left end and the right end are axially symmetrical about the top comb frame body. The left end and the right end are both composed of an integrally formed clamping part and a through part. The clamping part is provided in the foot groove by a clamping assembly, and the through part is located above the clamping part.

[0011] Both the left and right ends are provided with a first mounting protrusion and a second mounting protrusion. The first mounting protrusion is located on one side of the through portion, and both the through portion and the first mounting protrusion are hollow through structures. The second mounting protrusion is located on one side of the clamping portion. The two sets of mounting protrusions on the left and right ends are arranged opposite to each other. The two first mounting protrusions are respectively inserted into the first cavities at both ends of the top comb frame body, and the two second mounting protrusions are respectively inserted into the second cavities at both ends of the top comb frame body. In addition, the sidewall of each mounting protrusion is provided with a draft angle, and each mounting protrusion forms an interference fit with the corresponding cavity through the draft angle.

[0012] The first screw and the second screw correspond one-to-one with the left end and the right end, respectively. The first screw passes through the through part and the first mounting protrusion on the left end and extends into the first cavity, where it is threadedly connected to the internal thread. The second screw passes through the through part and the first mounting protrusion on the right end and extends into the first cavity, where it is threadedly connected to the internal thread.

[0013] Preferably, the top comb support foot has an elongated connecting hole on the connecting part, and the top comb support foot can be adjusted and installed on the combing machine by means of bolts and the connecting hole and the combing machine.

[0014] Preferably, both the left and right ends are made of nylon.

[0015] Preferably, the draft angle of the sidewalls of the first mounting protrusion and the second mounting protrusion in the left and right ends is 1.5°.

[0016] Preferably, the horizontal length of the sidewall of the first mounting protrusion and the second mounting protrusion is 3mm in both the left and right ends.

[0017] Preferably, the clamping assembly includes a compression spring, which is composed of an integrally formed support part and an elastic part. The support part is located in a preset support groove on the axial side wall of the mounting part, and the elastic part covers part of the outer wall of the through part at the left end or the right end by means of its arc-shaped structure, and at the same time covers the head of the first screw or the second screw.

[0018] The clamping assembly also includes a locking hole on the axial sidewall of the mounting part, a top comb plate that cooperates with the axial sidewall of the mounting part, and a locking screw that cooperates with the locking hole. The locking hole is located below the support groove. Through the cooperation of the locking hole and the locking screw, the top comb plate is pressed against the axial sidewall of the mounting part. The compression spring is located between the top comb plate and the mounting part. The compression spring is pressed against the axial sidewall of the mounting part by the top comb plate. Then, the elastic part of the compression spring presses the clamping part of the left end or the right end into the foot groove of the mounting part.

[0019] Preferably, the compression spring covers 50% of the circumference of the head of the first screw or the second screw.

[0020] The beneficial effects of this invention are as follows:

[0021] In general, this invention sets the top comb frame device as a split structure, with a first cavity and a second cavity at both ends of the top comb frame body, and a first mounting protrusion and a second mounting protrusion corresponding to the left and right ends. The cooperation of the double protrusions and double cavities realizes the double-point positioning and insertion between the end and the body, effectively preventing the end from rotating relative to the body during use, and significantly improving the installation stability and anti-torsion ability of the top comb frame under high-speed combing conditions. At the same time, a 1.5° draft angle is set on the side wall of the mounting protrusion and forms an interference fit with the corresponding cavity, so that the end gets tighter and tighter after insertion, which not only ensures the reliability of the connection, but also allows the end to be easily replaced by pulling it out with a tool after wear.

[0022] Furthermore, based on the interference fit that pre-fixes the end head to both ends of the top comb frame body, this invention further achieves double locking and fixing between the end head and the top comb frame body by passing the first screw and the second screw through the through-parts and the first mounting protrusion on the left and right ends, respectively, and threading them with the internal threads in the first holes at both ends of the top comb frame body. The interference fit provides initial frictional positioning and anti-torsional resistance, while the screw connection provides axial tension, ensuring that the end head will not loosen or shift due to vibration during high-speed reciprocating motion. When the end head wears out, it can be removed and replaced simply by unscrewing the corresponding screw in the opposite direction, without having to replace the entire top comb frame body, effectively reducing maintenance costs. In addition, the left and right ends are made of nylon, which utilizes the elastic deformation of nylon to form a tighter fit with the holes, and nylon is cheaper than aluminum alloy, further reducing spare parts costs.

[0023] Furthermore, in this invention, the clamping assembly achieves accurate positioning of the compression spring by cooperating with the support groove on the mounting part through the support part of the compression spring. The compression spring is pressed against the axial side wall of the mounting part by the top comb pressure plate and the locking screw, so that the elastic part of the compression spring covers the outer wall of the end through part by the arc structure and at the same time covers the screw head, and the coverage area is 50% of the circumference. This ratio takes into account both the clamping stability and the convenience of disassembly and assembly. At the same time, the elongated connecting hole opened on the connecting part of the top comb support foot allows the top comb support foot to be adjusted in position relative to the combing machine along the length direction of the connecting hole.

[0036] This embodiment provides a novel top comb holder device for a combing machine, such as... Figures 1 to 2 As shown, it includes a top comb support foot 1, a top comb frame body 2, a left end 3, a right end 4, and a clamping assembly for fixing the left end 3 and the right end 4 to the corresponding top comb support foot 1.

[0037] Specifically in this embodiment, such as Figures 2 to 3 As shown, there are two top comb supports 1, which are located at both ends of the top comb frame body 2. The top comb supports 1 are composed of an integrally formed connecting part 101 and a mounting part 102. The top comb supports 1 are mounted on the combing machine through the connecting part 101, and the mounting part 102 is used to mount the left end head 3 and the right end head 4 at both ends of the top comb frame body 2.

[0038] Specifically in the top comb support foot 1, such as Figure 3As shown, the connecting part 101 has an elongated connecting hole 1011. During installation, the connecting part 101 is connected to the mounting position on the combing machine by bolts. After the bolts pass through the connecting hole 1011, they cooperate with the corresponding part of the combing machine, thereby installing the top comb support 1 on the combing machine. Since the connecting hole 1011 is an elongated structure, the top comb support 1 can be adjusted relative to the combing machine along the length of the connecting hole 1011 when the bolts are not fully tightened, so as to correct the installation position of the top comb frame device. After the adjustment is in place, the bolts are tightened to fix the top comb support 1 on the combing machine. The mounting part 102 is generally plate-shaped or block-shaped, and a support groove 1021 is provided on its circumferential side wall.

[0039] like Figures 1 to 2 As shown, the main body 2 of the top comb frame is a long strip-shaped component. Both ends of the main body 2 of the top comb frame are provided with a first cavity 201 and a second cavity 202, and each first cavity 201 is provided with an internal thread.

[0040] like Figure 1 , Figure 4 and Figure 5 As shown, the left end 3 and the right end 4 are located at the two ends of the top comb frame body 2, and the left end 3 and the right end 4 are axially symmetrical about the top comb frame body 2. The left end 3 and the right end 4 are both composed of an integrally formed clamping part 5 and a through part 6. The clamping part 5 is set in the foot groove 1021 by a clamping assembly, and the through part 6 is located above the clamping part 5. In addition, the left end 3 and the right end 4 are made of nylon material.

[0041] Based on this, a first mounting protrusion 7 and a second mounting protrusion 8 are provided on both the left end 3 and the right end 4. The first mounting protrusion 7 is located on one side of the through part 6, and both the through part 6 and the first mounting protrusion 7 are hollow through structures. The second mounting protrusion 8 is located on one side of the clamping part 5.

[0042] Two sets of mounting protrusions on the left end 3 and the right end 4 are arranged opposite each other. The two first mounting protrusions 7 are respectively inserted into the first cavities 201 at both ends of the top comb frame body 2, and the two second mounting protrusions 8 are respectively inserted into the second cavities 202 at both ends of the top comb frame body 2. In addition, each mounting protrusion has a draft angle of 1.5° on its side wall and a horizontal length of 3mm on its side wall. Thus, each mounting protrusion forms an interference fit with the corresponding cavity through the draft angle.

[0043] Based on the above embodiments, a first cavity 201 and a second cavity 202 are respectively provided at both ends of the top comb frame body 2, and a first mounting protrusion 7 and a second mounting protrusion 8 are correspondingly provided on the left end 3 and the right end 4. By simultaneously inserting the two mounting protrusions into the two cavities, a two-point positioning and mating between the end and the top comb frame body 2 is achieved, effectively preventing the end from rotating relative to the top comb frame body 2 during use, and significantly improving the installation stability and torsional resistance of the top comb frame under high-speed combing conditions. At the same time, by setting a 1.5° draft angle on the side wall of the mounting protrusion and forming an interference fit with the corresponding cavity, the end becomes tighter and tighter after being inserted into the cavity, ensuring the reliability of the connection and allowing for easy replacement by pulling out the end with a tool after wear. In addition, the left end 3 and the right end 4 are made of nylon material. On the one hand, the elastic deformation of nylon forms a tighter fit with the cavity, and on the other hand, it reduces the manufacturing cost of the end. When it wears out, only the end needs to be replaced instead of the entire top comb frame body 2, effectively reducing maintenance costs.

[0044] In this technical solution, such as Figure 2 , Figure 6 As shown, the novel top comb holder device also includes a first screw 9 and a second screw 10, which correspond one-to-one with the left end 3 and the right end 4, respectively. The first screw 9 passes through the through part 6 and the first mounting protrusion 7 on the left end 3 and extends into the first cavity 201, and is threadedly connected to the internal thread. The second screw 10 passes through the through part 6 and the first mounting protrusion 7 on the right end 4 and extends into the first cavity 201, and is threadedly connected to the internal thread.

[0045] Based on the above embodiments, after the left end 3 and the right end 4 are interference-fitted to both ends of the top comb frame body 2, the first screw 9 and the second screw 10 pass through the through portion 6 and the first mounting protrusion 7 on the left end 3 and the right end 4 respectively, and are threadedly connected to the internal thread portion in the first cavity 201 at both ends of the top comb frame body 2, thereby realizing the double locking and fixing between the end and the top comb frame body 2.

[0046] Overall, the interference fit provides initial frictional positioning and anti-torsional resistance, while the screw connection provides axial tension, ensuring that the end head will not loosen or shift due to vibration during high-speed reciprocating motion, further improving the connection reliability and positional stability of the top comb frame body 2 during long-term operation. Furthermore, when the end head wears out, it can be easily removed from the top comb frame body 2 by simply unscrewing the corresponding screw in the opposite direction. The disassembly process is simple and convenient, and it does not require replacing the entire top comb frame body 2, effectively reducing maintenance costs.

[0047] Next, this application will provide a detailed description of the specific structure of the clamping assembly and its clamping method for the clamping part 5 in the left end 3 and the right end 4.

[0048] Specifically, the clamping components are respectively set at the two top comb support feet 1. For ease of description, the following description only takes the clamping component at one of the top comb support feet 1 as an example. The structure and assembly method of the other top comb support foot 1 are the same.

[0049] like Figures 2 to 3 , Figures 7 to 9 As shown, the clamping assembly includes a compression spring 11, which is composed of an integrally formed support portion 1101 and an elastic portion 1102. The support portion 1101 is located in a pre-set support groove 12 on the axial sidewall of the mounting portion 102. The support groove 12 can position the support portion 1101 and prevent the compression spring 11 from moving within a large range during assembly or operation. The elastic portion 1102, with its arc-shaped structure, covers part of the outer wall of the through portion 6 of the left end 3 or the right end 4, and simultaneously covers the head of the first screw 9 or the second screw 10. In this embodiment, the circumferential range of the compression spring 11 covering the head of the first screw 9 or the second screw 10 is 50%. The specific structure is as follows. Figure 9 As shown, through this covering structure, the compression spring 11 can shield and limit the screw head, and can transmit the elastic force to the end, so that the end is stably held in the support groove 1021 of the top comb support foot 1.

[0050] The clamping assembly also includes a locking hole 13 on the axial sidewall of the mounting part 102, a top comb plate 14 that cooperates with the axial sidewall of the mounting part 102, and a locking screw 15 that cooperates with the locking hole 13. The locking hole 13 is located below the support groove 12. The top comb plate 14 is pressed against the axial sidewall of the mounting part 102 by the cooperation of the locking hole 13 and the locking screw 15. The compression spring 11 is located between the top comb plate 14 and the mounting part 102. The compression spring 11 is pressed against the axial sidewall of the mounting part 102 by the top comb plate 14. Then, the elastic part 1102 of the compression spring 11 presses the clamping part 5 of the left end 3 or the right end 4 into the foot groove 1021 of the mounting part 102.

[0051] When assembling the clamping assembly, first place the clamping part 5 of the left end 3 or the right end 4 into the foot groove 1021 of the corresponding mounting part 102, then place the support part 1101 of the compression spring 11 into the support groove 12, so that the elastic part 1102 of the compression spring 11 fits against the outer wall of the end through part 6 and covers the head of the corresponding screw; then place the top comb pressure plate 14 on the outer side of the axial side wall of the mounting part 102, so that the compression spring 11 is located between the top comb pressure plate 14 and the mounting part 102, and finally screw in the locking screw 15.

[0052] As the locking screw 15 is gradually tightened, the top comb pressure plate 14 moves toward the mounting part 102 and presses the compression spring 11 against the axial side wall of the mounting part 102. After the compression spring 11 is compressed, the elastic part 1102 generates an elastic restoring force and presses the clamping part 5 of the left end 3 or the right end 4 into the foot groove 1021 of the mounting part 102. Thus, the left end 3 and the right end 4 can be stably clamped on the two top comb feet 1 respectively.

[0053] The installation process for this device is as follows:

[0054] First, the two top comb feet 1 are installed in their corresponding positions on the combing machine using bolts, and the positions of the two top comb feet 1 are initially adjusted using the elongated connecting holes 1011 on the connecting part 101. Then, the left end 3 and the right end 4 are installed at both ends of the top comb frame body 2, so that the first mounting protrusion 7 and the second mounting protrusion 8 are inserted into the corresponding first cavity 201 and the second cavity 202, respectively, and the draft angle of the side wall of the mounting protrusion forms an interference fit with the corresponding cavity. Next, the first screw 9 and the second screw 10 are screwed into the internal threads of the first cavities 201 at both ends of the top comb frame body 2, respectively, to fix the left end 3 and the right end 4 to the top comb frame body 2. Finally, the clamping parts 5 at both ends of the top comb frame body 2 are placed in the foot grooves 1021 of the two top comb feet 1, the compression spring 11 and the top comb pressure plate 14 are installed, and the locking screw 15 is tightened, so that the compression spring 11 presses and fixes the left end 3 and the right end 4.

[0055] During the operation of the combing machine, the top comb frame body 2 reciprocates or moves at high speed with the combing machine. Since the left end 3 and right end 4 are made of nylon and are connected to the top comb frame body 2 through independent end structures, when the top comb frame body 2 is subjected to dynamic loads and undergoes longitudinal elastic deformation, the nylon end can buffer the contact and relative movement between the top comb frame body 2 and the top comb support foot 1, thereby reducing the rigid micro-motion friction between the top comb support foot 1, the compression spring 11, and the top comb frame body 2. At the same time, the compression spring 11 presses the end through the arc-shaped elastic part 1102, so that the end can be stably held in the support foot groove 1021, reducing the installation position displacement caused by loosening of the top comb frame device.

[0056] When the clamping part 5 of the left end 3 or the right end 4 wears out due to long-term use, the corresponding locking screw 15 can be loosened first, the top comb pressure plate 14 and the compression spring 11 can be removed, and then the corresponding first screw 9 or second screw 10 can be removed. The worn left end 3 or right end 4 can be removed from the top comb frame body 2 and the top comb support foot 1, and a new end can be installed. Since the top comb frame body 2 does not need to be completely removed or replaced, maintenance costs can be reduced, maintenance time can be shortened, and the effective operating time of the combing machine can be increased.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
