Description

Technical Field

[0001] This utility model relates to the field of rope head forming technology, specifically a rope head cold and hot forming machine. Background Technology

[0002] Some clothing and shoes have drawstrings, such as hat straps and shoelaces. To prevent the ends of the drawstrings from becoming frayed and affecting their use, and also for ease of use and aesthetic enhancement, caps are often installed at the ends of the drawstrings. These caps can be made of metal or plastic, with metal caps being more popular with consumers. When installing and securing metal caps, a stamping and finishing device is required to finish the metal cap that is fitted onto the end of the drawstring.

[0003] However, existing sealing machines require manual operation, have low efficiency in installing clamps, are prone to loosening during installation, and have limited functionality.

[0004] To address the aforementioned deficiencies, Chinese Patent No. CN215554417U discloses a rope and cord closing machine, comprising a closing machine body installed on the upper surface of the ground, with a supporting base fixedly installed at its lower end; a fixing groove formed on the upper surface of the base, with the fixing block nested on its inner surface, and a mold connected to the top of the inner surface; a support frame installed in the middle of the inner surface of the closing machine body, with a cylindrical spur gear attached to its lower surface and a threaded rod passing through it; a limit block and a positioning block respectively embedded at the top and bottom of the outer surface of the threaded rod; and two sets of motors driving two sets of extrusion devices to move. In use, the cylindrical spur gear installed in the middle of the closing machine body drives the lower pressure block to fall quickly, reducing usage time. Furthermore, the addition of a horizontally connected ejector head effectively performs secondary extrusion, facilitating operation.

[0005] The aforementioned device uses the ejector head for secondary extrusion during use. However, when the device is used to close the rope head, the temperature control is not precise enough, which may result in poor molding effect, or the operation process is complicated, affecting production efficiency and having a single function. Summary of the Invention

[0006] The purpose of this utility model is to provide a rope head cold and hot sealing forming machine to solve the problems of inaccurate temperature control, complicated operation and limited function of rope sealing machines mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a rope head cold and hot closing forming machine, comprising an electrical control box, an all-in-one touch screen on the outer surface of the electrical control box, a servo motor on the inner side of the electrical control box, a servo motor reducer on the connecting part of the servo motor, a synchronous pulley on the outer surface of the servo motor reducer, a motor ball screw on the outer surface of the synchronous pulley, and a constant temperature controlled closing forming mechanism and a clamping mechanism on the outer surface of the motor ball screw.

[0008] Furthermore, the closing forming mechanism includes a lead screw seat connecting rod, the outer surface of which is provided with a linear slide rail seat, and the outer surface of which is provided with a linear slide rail.

[0009] Furthermore, the outer surface of the linear slide rail is provided with a pressure block assembly, and the outer surface of the pressure block assembly is provided with upper and lower mold clamping columnar springs.

[0010] Furthermore, the clamping mechanism includes an upper mold sliding assembly, the outer surface of which is provided with upper and lower mold clamping columnar springs, and the outer surface of which is provided with an upper mold.

[0011] Furthermore, a clamp push rod assembly is provided on the outer surface of the upper mold sliding assembly, and an upper mold heating assembly is provided on the outer surface of the upper mold.

[0012] Furthermore, the clamp push rod assembly is disposed on the inner side of the electrical control box, the inner side of the electrical control box is provided with a lower mold, the outer surface of the lower mold is provided with a heat insulation block and a lower mold heating assembly, the bottom surface of the lower mold heating assembly is provided with an organic platform base plate, and clamp assemblies are provided on both sides of the lower mold.

[0013] Furthermore, the inner side of the electrical control box is provided with a tapering inclined block assembly, the inner side of the electrical control box is provided with a tapering push rod assembly, and the outer surface of the electrical control box is provided with a safety guard plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) By setting the closing forming mechanism, the cold and hot closing forming of the rope head can be realized, and the temperature control is more precise. The upper mold heating component and the lower mold heating component in the closing forming mechanism can heat the upper / lower closing mold respectively. After the upper / lower closing mold is closed, the rope head can reach the ideal forming temperature during the closing process, thereby improving the forming effect. (2) The constant temperature control in the closing mechanism can ensure the stability of the heating temperature and avoid molding quality problems caused by temperature fluctuations. Through the drive of servo motor and servo motor reducer, as well as the transmission of synchronous pulley and motor ball screw, the precise movement and positioning of the closing molding mechanism are realized, which further improves the molding accuracy and efficiency. (3) By setting up clamping components and clamping push rod components, the rope can be quickly clamped (the cross section of the rope becomes smaller) and positioned, avoiding the rope from being pinched by the upper and lower closing molds. The setting of safety guard plate can also ensure the safety of operators and improve the safety performance of the equipment. (4) By setting the closing inclined block assembly and closing push rod assembly, together with the upper mold sliding assembly and pressure block assembly, the rope head is stably pushed and formed during the closing process. The design of the closing inclined block assembly enables the rope head to be gradually subjected to pressure during the pushing process, thereby achieving uniform closing and avoiding the problem of poor forming caused by uneven pressure.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1: Please refer to Figure 1 - Figure 6 The present invention provides the following technical solution: a rope head cold and hot closing forming machine, including an electrical control box 1, a touch screen all-in-one machine 2 on the outer surface of the electrical control box 1, a servo motor 3 on the inner side of the electrical control box 1, a servo motor reducer 4 on the connecting part of the servo motor 3, a synchronous pulley 5 on the outer surface of the servo motor reducer 4, a motor ball screw 6 on the outer surface of the synchronous pulley 5, and a constant temperature controlled closing forming mechanism and a clamping mechanism on the outer surface of the motor ball screw 6.

[0019] With its specially designed end-forming mechanism, the rope and webbing heads can be precisely end-formed using both hot and cold methods. The constant temperature control ensures temperature stability during the end-forming process, thereby improving the forming effect. This rope and webbing head hot and cold end-forming machine can perform cold / hot end-forming on various rope and webbing heads (including seamless metal heads, plastic heads, semi-open metal heads, die-cut heads, shoe and hat heads, bullet heads, webbing heads, etc.), cold-press end-forming on metal (zinc alloy, drawn copper, lathe copper, stainless steel, etc.) rope and webbing heads, and hot-press end-forming on plastic (ABS, PC, etc.) rope and webbing heads, achieving multi-purpose functionality. The specific operation is as follows: Place the rope end that needs to be closed into the closing forming lower mold 16, turn on the switch, and the servo motor 3 rotates forward at high speed and descends. The motor passes through the servo motor reducer 4, which is connected to the synchronous pulley 5, and then through the synchronous belt to the synchronous pulley 5 at the load end. The synchronous pulley 5 at the load end is connected to the motor ball screw 6, which drives the linear slide rail 9 at the end of the screw seat connecting rod 7. The linear slide rail 9 drives the upper mold sliding assembly 12, the left / right clamp push rod assembly 13, the upper mold heating assembly 14, the upper mold 15, and the closing inclined block assembly 19. The left / right clamp push rod assembly 13... The left and right ends are clamped by the inclined block mechanism to reduce the cross section of the rope and prevent the rope head from being damaged during the forming process. When the upper mold 15 and the lower mold 16 are pressed together and reach the mold closing position, the servo motor 3 switches to low speed and continues to rotate forward and descend. In the low speed state, the forming inclined block assembly 19 drives the forming push rod assembly 20 to move forward. The forming push rod assembly 20 drives the forming mold push plate to move forward at low speed to form the rope head. After the forming mold push plate reaches the set forming position, the molding stops. When the pressure holding time is reached, the motor reverses at high speed and rises to the waiting position. Thus, the cold and hot forming of the rope head is completed.

[0020] Example 2: Based on Example 1, please refer to... Figure 2 - Figure 5 The linear slide rail 9 was also disclosed, and its specific structure is as follows: The closing forming mechanism includes a lead screw seat connecting rod 7, a linear slide rail seat 8 is provided on the outer surface of the lead screw seat connecting rod 7, a linear slide rail 9 is provided on the outer surface of the linear slide rail seat 8, a pressure block assembly 10 is provided on the outer surface of the linear slide rail 9, and upper and lower die clamping columnar springs 11 are provided on the outer surface of the pressure block assembly 10. The clamping mechanism includes an upper die sliding assembly 12, upper and lower die clamping columnar springs 11 are provided on the outer surface of the upper die sliding assembly 12, and an upper die 15 is provided on the outer surface of the upper die sliding assembly 12.

[0021] The engagement of the lead screw seat connecting rod 7 with the linear slide rail seat 8 and the linear slide rail 9 in the closing mechanism is achieved by... Figure 3 It is understood that the closing and forming mechanism has stable and precise movement characteristics during operation, improving the operating accuracy of the equipment and effectively extending its service life. The setting of the pressure block assembly 10 and the upper and lower die clamping column springs 11 ensures that the upper / lower closing molds close in advance during the closing and forming process of the rope head. After the molds close, the closing inclined block assembly 19 moves forward to push the closing push rod assembly 20 to perform closing and forming. In order to separate the closing of the upper / lower closing molds and the action of the closing push rod assembly 20, the upper and lower die clamping column springs 11 are elastically designed. This will not cause damage to the rope head and further ensure the stability and accuracy of the closing operation.

[0022] Example 3: Based on Example 1, please refer to... Figure 1 - Figure 6 The lower mold 16 is also disclosed, and its specific structure is as follows: the outer surface of the upper mold sliding component 12 is provided with a left / right clamp push rod component 13, the outer surface of the upper mold 15 is provided with an upper mold heating component 14, the left / right clamp push rod component 13 is provided on the support block of the linear slide rail 9, the machine base plate 22 is provided with a lower mold 16, the outer surface of the lower mold 16 is provided with a heat insulation block and a lower mold heating component 17, the bottom surface of the lower mold heating component 17 is provided with the machine base plate 22, the left and right sides of the lower mold 16 are equally provided with left / right clamp components 18, the support block of the linear slide rail 9 is provided with a tapering inclined block component 19, the inner side of the machine base plate 22 is provided with a tapering push rod component 20, and the front outer side of the machine base plate 22 is provided with a safety guard plate 21.

[0023] The coordinated action of the lower mold 16 with the left / right clamp push rod assembly 13 and the left / right clamp assembly 18, by Figure 5As can be seen, the rope head is positioned quickly and stably. The upper mold heating component 14 and the lower mold heating component 17 conduct heat to the upper mold 15 and the lower mold 16 respectively to maintain a constant temperature. After the upper mold 15 and the lower mold 16 are closed, the closing inclined block component 19 and the closing push rod component 20 advance the closing mechanism, realizing precise temperature control of the rope head for both hot and cold closing. This allows for the heating and molding of the plastic part, avoiding the problem of poor molding effect and further improving the molding effect. This simplifies the operation process and improves production efficiency. The safety guard plate 21 ensures safety during operation and prevents accidents.
