Description

Technical Field

[0002] This invention relates to the field of welding processing technology, and in particular to a welding processing device for manufacturing warp yarn placement tubes of a slitting and sizing machine. Background Technology

[0003] Slitting and sizing machines are textile equipment that combine warping and sizing processes into one. They are suitable for slitting and warping of various fabrics, including fine wool textiles, chemical fiber filament fabrics, yarn-dyed fabrics, silk fabrics, towel fabrics, and special industrial fabrics. The placement cylinder used in the machine provides the initial tension and unwinding power of the warp yarns.

[0004] End rollers are also provided at both ends of the placement cylinder, which are generally fixed to both ends of the placement cylinder by welding. For example, the existing patent document with publication number CN118720607A discloses a pre-embedded sleeve welding processing equipment. The scheme discloses that it "includes a machine body for placing the pre-embedded sleeve and a fixed frame fixedly installed on the top of the machine body. A cylinder is fixedly installed on the top of the fixed frame. The output end of the cylinder slides through the fixed frame and is fixedly installed with a drive plate. A clamping and positioning unit and a locking welding unit are provided between the drive plate and the machine body. The locking rod is inserted into the locking groove and the pressing plate is pressed on the top of the positioning plate to realize the locking and positioning of the clamping plate. The sliding steel ball at the bottom of the rotating disk is also pressed on the top of the pre-embedded iron plate, thus playing a stabilizing and reinforcing role for the welding gun. The sliding sleeve is sleeved on the outside of the cylinder and the bottom of the drive plate is pressed on the top of the cylinder, thereby realizing the functions of fitting between the cylinder and the pre-embedded iron plate, clamping and positioning of the pre-embedded iron plate by the clamping plate, and improving the welding stability of the welding gun."

[0005] In the above-mentioned solution, when welding the end of the sleeve, it is placed vertically, and only one end can be aligned and welded at a time, resulting in low work efficiency. In existing technology, when welding is required at both ends of the sleeve, it is generally placed horizontally, and a roller assembly drives the sleeve to rotate. The existing roller assembly is driven by a motor to rotate the workpiece. After the sleeve is placed, the end roller is placed at its end, and then it is welded and fixed by a welding gun mechanism. However, this process lacks a limiting function at both ends of the sleeve. Yes, when its roller assembly drives its rotation, it may cause movement in the axial direction. Furthermore, the end roller lacks a good positioning effect. In the existing technology, in order to facilitate the welding and fixing of the end roller, a locking groove is generally provided at the end of the placement cylinder. The base of the end roller is locked in the locking groove, and then a welding gun mechanism is used to weld the contact gap between the base and the locking groove. That is, the circular base of the end roller is locked with the circular locking groove at the end of the placement cylinder. In other words, there is no clamping and positioning structure for the base of the end roller to meet its positioning requirements.

[0006] To address these issues, this invention proposes a welding processing device for manufacturing warp yarn placement cylinders in a slitting and sizing machine. Summary of the Invention

Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-10 A welding processing device for manufacturing warp yarn placement cylinders of a slitting and sizing machine includes a support platform 2 and a base 1 disposed at the bottom of the support platform 2. Drive wheel devices 21 are symmetrically arranged at both ends of the top of the support platform 2. The drive wheels in the drive wheel devices 21 are driven to rotate by a drive motor, providing a rotation effect for the workpiece; that is, the drive wheel devices 21 are used to support and drive the warp yarn placement cylinder 3 to rotate. The base 1 is also equipped with a welding gun device 5, which is used to weld the joint between the bottom plate of the end roller 4 and the warp yarn placement cylinder 3. A welding processing auxiliary mechanism is also provided on the base 1; the welding processing auxiliary mechanism includes a limiting roller 601, which is used to limit the chassis at the bottom of the end roller 4; the welding processing auxiliary mechanism also includes a positioning structure and an adjustment component, which work together to adjust the position of the limiting roller 601 to improve its flexibility of use.

[0023] According to the appendix Figure 1 -Appendix Figure 4 As shown, this solution involves welding the warp yarn placement cylinder 3, where the end rollers 4 are welded and fixed to both ends of the warp yarn placement cylinder 3. During this process, a welding auxiliary mechanism is provided to assist in the welding of the warp yarn placement cylinder 3.

[0024] The limiting roller 601 provides a limiting effect on the end of the warp yarn placement cylinder 3 and the end roller 4. That is, during the rotation of the warp yarn placement cylinder 3 driven by the drive wheel device 21, the warp yarn placement cylinder 3 is prevented from shifting along its axial direction, so as to ensure the welding quality of the warp yarn placement cylinder 3.

[0025] Based on this, the solution uses the bearing rod 701 in conjunction with the positioning structure and adjustment components. On the one hand, the position of the limiting roller 601 can be adjusted to improve its working flexibility. On the other hand, the limiting roller 601 can also provide a squeezing effect on the base at the bottom of the end roller 4 to ensure the tight fit between the base of the end roller 4 and the end locking groove of the warp yarn placement cylinder 3. This has a positive effect on improving the welding quality.

[0026] Furthermore, this solution also includes an auxiliary component on the support plate 702, which provides a cleaning function for the gap where the base of the end roller 4 contacts the end engagement groove of the warp yarn placement cylinder 3 through the air jet head 1002 and the cleaning component. It also provides a cooling effect for the welding position after welding.

[0027] Combined with the appendix Figure 5 -Appendix Figure 8 As shown, the limiting roller 601 is located on one side of one end of the support rod 701, and the support rod 701 is movably inserted into the support plate 702. The support rod 701 is positioned by a positioning structure, which includes a mounting screw hole 801 in the support plate 702 and a positioning stud 802 that is threadedly connected to the mounting screw hole 801. A knob body 803 is fixedly provided at one end of the positioning stud 802, which is used to improve the ease of tightening and loosening the positioning stud 802.

[0028] Combined with the appendix Figure 1 -Appendix Figure 4 As shown, when welding the two ends of the warp yarn placement cylinder 3, the cylinder is first placed horizontally on the drive wheel device 21 on the support platform 2. That is, the bottom of the warp yarn placement cylinder 3 is supported by the drive wheel. The drive wheel device 21 also provides a rotation function for the warp yarn placement cylinder 3. After the warp yarn placement cylinder 3 is placed, the base of the end roller 4 is locked in the locking groove at the end of the warp yarn placement cylinder 3. At this time, the limiting roller 601 is used to limit the warp yarn placement cylinder 3 and the end roller 4.

[0029] The control assembly includes a bearing sliding seat 901 movably disposed within a sliding cavity; a connecting seat is fixedly disposed at the bottom end of the support plate 702, and this connecting seat is fixed to the bearing sliding seat 901 by screws; the bearing sliding seat 901 is connected to a control screw 902, which drives the bearing sliding seat 901 to move within the sliding cavity, which is disposed within the mounting carrier 903. One end of the control screw 902 extends to the outside of the mounting carrier 903, and a handle body 904 is fixedly disposed at the end of the control screw 902; a locking nut 905 is also threadedly connected to the control screw 902 for locking the control screw 902.

[0030] First, the bearing sliding seat 901 is moved by adjusting the lead screw 902. The bearing sliding seat 901 drives the support plate 702 and the bearing rod 701 on the support plate 702 to move along the axis of the warp yarn placement cylinder 3 until the limiting roller 601 on the bearing rod 701 contacts the base of the end roller 4. Then, the position of the limiting roller 601 is adjusted by the bearing rod 701. While adjusting the limiting roller 601, it is necessary to ensure that the air jet head 1002 and the cleaning component in the auxiliary components on the bearing rod 701 are aligned with the welding gap at the end of the warp yarn placement cylinder 3. That is, the gap where the base of the end roller 4 contacts the end locking groove of the warp yarn placement cylinder 3 is aligned with the air jet head 1002 and the cleaning component. Then, the bearing rod 701 is positioned by the positioning structure.

[0031] The positioning operation of the support rod 701 is achieved by tightening the positioning stud 802 through the knob body 803, so that the positioning stud 802 presses against one side of the support rod 701 to achieve the positioning of the support rod 701.

[0032] To further improve the tightness of the engagement between the base of the end roller 4 and the end engagement groove of the warp yarn placement cylinder 3, the carrier sliding seat 901 can be moved and adjusted by adjusting the screw 902. That is, the screw 902 can be rotated by the handle body 904 to drive the carrier sliding seat 901, thereby making the limiting roller 601 exert a corresponding squeezing effect on the base of the end roller 4. Finally, the locking nut 905 set on the adjusting screw 902 is tightened. This process provides a limiting effect for the base of the end roller 4 and the warp yarn placement cylinder 3. On this basis, it also ensures the tightness of the engagement between the base of the end roller 4 and the end engagement groove of the warp yarn placement cylinder 3, which is helpful for subsequent welding processing.

[0033] Then, the welding process is carried out by the welding gun device 5, which is to weld the contact gap between the base of the end roller 4 and the engagement groove of the warp yarn placement cylinder 3, and to weld the seam to be welded in a timely manner.

[0034] Combined with the appendix Figure 7 -Appendix Figure 10 As shown, when welding the seam to be welded between the warp yarn placement cylinder 3 and the end roller 4 using the welding gun device 5, this solution also provides welding assistance by setting an auxiliary component on the support rod 701.

[0035] The auxiliary component includes a loading cavity 1001 disposed in the support plate 702, which is used to install the jet head 1002. The jet head 1002 is inserted into the loading cavity 1001, and a mounting plate 1003 is also disposed on the outside of the jet head 1002. The mounting plate 1003 is fixedly connected to the support plate 702 by screws, and the jet head 1002 is connected to the air delivery hose 1004.

[0036] On the other hand, the auxiliary component also includes a cleaning component, which is used to clean the joint between the bottom plate of the end roller 4 and the warp placement cylinder 3. The cleaning component includes a semi-ring 1101, of which two sets are provided, and the two sets of semi-rings 1101 are spliced ​​to form a bearing ring. A fixing foot 1102 is also provided on the outside of the semi-ring 1101, and the fixing foot 1102 is fixed to the support plate 702 by screws. A receiving groove 1103 is also provided in the semi-ring 1101, and a cleaning brush structure is provided in the receiving groove 1103. The structure includes a cleaning brush body 1106; the cleaning brush body 1106 is disposed on a loading strip 1105, which is an arc-shaped strip; positioning magnetic pieces 1104 are embedded in one side of the loading strip 1105 and in the receiving groove 1103, the loading strip 1105 and the receiving groove 1103 are adapted to and engaged, and are attracted and positioned by the positioning magnetic pieces 1104 of both; a set of loading strips 1105 is disposed in one receiving groove 1103, and the cleaning brush bodies 1106 on the two loading strips 1105 form an annular brush, and the annular brush is disposed around the side of the mounting jet head 1002.

[0037] While adjusting the limiting roller 601 through the control components and positioning structure, the position of the auxiliary components is also adjusted. In particular, the air jet head 1002 and the annular brush in the auxiliary components need to be adjusted to align with the weld seam at the end of the warp yarn placement cylinder 3. After adjusting the position of the limiting roller 601, it is necessary to ensure that the annular brush is in contact with the weld seam and that the air jet head 1002 is not in contact with the weld seam.

[0038] Then from the appendix Figure 1 -Appendix Figure 4 As shown, before welding the seam to be welded formed by the warp yarn placement cylinder 3 and the end roller 4 using the welding gun device 5, the warp yarn placement cylinder 3 rotates. During this process, the annular brush provides a cleaning effect on the seam to be welded. That is, the cleaning brush body 1106 set on the loading bar 1105 provides a cleaning effect on the dust and impurities at the seam to be welded, which has a positive effect on the welding work of the seam to be welded. At the same time, the gas sprayed from the jet head 1002 also has a blowing cleaning effect on the seam to be welded. Similarly, it also has a cleaning effect on the dust and impurities adhering to the cleaning brush body 1106, so as to ensure the cleanliness of the cleaning brush body 1106.

[0039] However, during this process, since the end roller 4 is engaged with the engagement groove at the end of the warp yarn placement cylinder 3, the drive wheel in the drive wheel device 21 is driven to rotate by the drive motor, providing a rotation effect for the workpiece. Therefore, when the drive wheel device 21 drives the warp yarn placement cylinder 3 to rotate, the end roller 4 may not rotate. At this time, the welding gun device 5 can be used to spot weld the seam to be welded, that is, to provide a fixed connection between the base of the end roller 4 and the warp yarn placement cylinder 3. After welding is stopped, the drive wheel device 21 drives the warp yarn placement cylinder 3. During this process, the end roller 4 at the end of the warp yarn placement cylinder 3 will also rotate together. After the warp yarn placement cylinder 3 rotates one revolution, the welding gun device 5 is used to weld the seam to be welded at the end of the warp yarn placement cylinder 3.

[0040] After the warp yarn placement cylinder 3 is rotated once, the end roller 4 can be welded and fixed to the end of the warp yarn placement cylinder 3. During this process, the gas sprayed from the jet nozzle 1002 not only cleans the weld seam but also provides a blowing and cooling effect on the welded area.

[0041] Combined with the appendix Figure 9 -Appendix Figure 10 As shown, the cleaning component is designed to be detachable. The loading strip 1105 for loading the cleaning brush 1106 can also be removed. When the cleaning brush 1106 needs to be replaced or disassembled for cleaning, the loading strip 1105 is pulled outward until it separates from the receiving groove 1103 in the semi-ring 1101, which releases the magnetic positioning sheet 1104. When replacing the cleaning brush 1106, the loading strip 1105 for loading the cleaning brush 1106 is placed directly in the receiving groove 1103 and positioned by the magnetic adsorption of the magnetic positioning sheet 1104.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
