Description

Technical Field

[0001] This utility model relates to the field of textile and garment machinery and equipment technology, and in particular to a clamping nozzle on a button-making machine. Background Technology

[0002] In the production and processing of clothing, bags and other products, button-attaching machines are key equipment for connecting buttons to fabric. Their core function is to complete the conveying, positioning and pressing-attaching process of buttons through a specific structure to meet the requirements of industrial mass production for processing efficiency and fastening quality. Currently, button-attaching machines in the industry are usually equipped with corresponding conveying mechanisms and execution components to ensure that the buttons can reach the designated processing position and complete the pressing action through the power provided by the drive components. At the same time, they need to be compatible with buttons of different sizes and specifications to meet diverse product processing needs.

[0003] Existing button-fastening machines suffer from poor coordination, requiring separate steps for button feeding, positioning, and button pressing. The two actions cannot be synchronized, resulting in low overall button-fastening efficiency. Furthermore, the lack of elastic buffer components in the devices leads to rigid contact between the pressing component and the part to be buttoned, making it prone to button positioning deviations due to excessive impact force and potentially causing wear on core components. To address these issues, we propose a clamping jaw for the button-fastening machine. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a clamping mouth for a button-fastening machine, which can solve the problems of poor linkage between existing button-fastening machine devices, which require separate steps to complete the button feeding and positioning and the pressing and buttoning action, and the two cannot be synchronized, resulting in low overall button-fastening efficiency. At the same time, the device lacks elastic buffer components, and the pressing component and the part to be buttoned are mostly in hard contact, which can easily cause button positioning deviation due to excessive impact force, and may also cause wear of core components.

[0006] To solve the above-mentioned technical problems, this utility model provides a clamping mouth for a button-attaching machine, which adopts the following technical solution: it includes a main cylinder, a push rod that moves vertically through the main cylinder, a base block that is clamped directly below the main cylinder, the base block having a left mounting wing and a right mounting wing integrally formed, a first clamping mouth correspondingly mounted on the left mounting wing, a second clamping mouth correspondingly mounted on the right mounting wing, a ramp block integrally formed on the lower outer side of the push rod, a mold clamping block that is detachably connected to the bottom end of the push rod by a thread, and a button groove adapted to the button to be attached is opened at the front between the first clamping mouth and the second clamping mouth.

[0007] Optionally, the first clamp is axially rotatably connected to the left mounting wing via a shaft pin, and the second clamp is axially rotatably connected to the right mounting wing via a shaft pin. Slots are provided on the top of both the first and second clamps. Metal springs are symmetrically arranged on the left and right sides of the base block. The metal springs are fastened to the base block by bolts, and the end of the metal spring away from the base block is inserted into the slot of the first clamp and the slot of the second clamp respectively. The metal spring is in a pre-compression state.

[0008] Optionally, a through groove is provided through the middle of the first clamp and the second clamp. The inner diameter of the through groove is adapted to the outer diameter of the push rod. The push rod is movably inserted into the through groove. The inner sidewall of the first clamp above the through groove and the inner sidewall of the second clamp above the through groove are both provided with inclined slopes. The inclination angle of the inclined slopes matches the inclination angle of the inclined block on the outer side of the push rod.

[0009] Optionally, a fastening hole is provided on the lower rear side of the first clamp, and a fastening bolt is inserted into the fastening hole. The first clamp is detachably connected to a top buckle limiting block through the fastening bolt. A groove adapted to the buckle to be fastened is provided on the top of the top buckle limiting block. The left side of the groove is a closed structure and the right side is an open structure. The buckle can slide out from the right side of the groove. The bottom surface of the buckle groove at the front between the first clamp and the second clamp is adapted to the top surface of the top buckle limiting block.

[0010] Optionally, the push rod further includes a movable rod and a force-applying spring. The push rod has a movable cavity inside along its own axial direction. The movable rod is vertically limited and assembled in the movable cavity. The force-applying spring is disposed in the movable cavity and located directly above the movable rod. One end of the force-applying spring abuts against the top of the movable cavity, and the other end abuts against the top of the movable rod, and always applies an elastic force downward along the axial direction of the movable cavity to the movable rod. The movable rod and the push rod are provided with a mutually cooperating limiting structure.

[0011] Optionally, the bottom end of the movable rod is provided with a threaded groove, and different specifications of mold blocks can be detachably installed in the threaded groove through threaded engagement.

[0012] In summary, this utility model has at least one of the following beneficial effects: 1. By installing a detachable top buckle limiting block and mold clamping blocks of different specifications, the top buckle limiting block is connected to the first clamping mouth by fastening bolts, and the mold clamping block is connected to the movable rod by threads, thus achieving the purpose of adapting to the processing needs of different specifications of buttons. At the same time, with the pre-compression effect of the force spring on the movable rod, it is ensured that buttons of different specifications can be stably locked and positioned, avoiding positioning deviation or falling off problems caused by differences in button specifications. This realizes the flexible adaptation of the device to diverse buttoning needs and improves the versatility of the equipment.

[0013] 2. By installing an integrally formed ramp block, a first and second clamp with an inclined slope, and a pre-compressed metal spring, the downward movement of the push rod and the opening and closing of the clamp are synchronized. When the main cylinder drives the push rod to move downward, the ramp block and the inclined slope cooperate to convert the vertical thrust into a lateral force, pushing the clamp to open against the spring force. At the same time, the spring can drive the clamp to automatically reset. No additional drive structure is needed to control the clamp movement, reducing the use of independent drive components, simplifying the overall structure of the device, reducing the difficulty of component timing matching, and avoiding efficiency loss caused by step-by-step actions.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0021] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0022] Example 1, refer to Figure 1-4 In this embodiment, to address the issue of poor coordination in existing button-fastening machines, the button feeding and positioning and the button-fastening action must be completed in separate steps, which cannot be synchronized, resulting in low overall button-fastening efficiency. Furthermore, the lack of elastic buffer components in the device means that the pressing component and the part to be buttoned are mostly in hard contact, which can easily lead to button positioning deviation due to excessive impact force and may also cause wear on core components. This utility model discloses a clamping nozzle for a button-fastening machine. The assembly includes a main cylinder 1, with a push rod 2 moving vertically through it. A base block 3 is positioned directly below the main cylinder 1. The base block 3 has a left mounting wing 31a and a right mounting wing 31b integrally formed. A first clamping nozzle 4a is mounted on the left mounting wing 31a, and a second clamping nozzle 4b is mounted on the right mounting wing 31b. A ramp block 21 is integrally formed on the lower outer side of the push rod 2. A mold clamping block 5a is detachably connected to the bottom of the push rod 2 via a thread. A snap groove 41, which matches the button to be snapped, is provided at the front between the first clamping nozzle 4a and the second clamping nozzle 4b. The base block 3, which is fixedly positioned directly below the main cylinder 1 by a snap-fit ​​mechanism, serves to support and position the entire clamping nozzle assembly. Furthermore, its integrally formed left mounting wing 31a and right mounting wing 31b provide an installation reference for the first clamping nozzle 4a and the second clamping nozzle 4b, ensuring that the two clamping nozzles can be assembled in a symmetrical and stable manner. The inclined block 21 integrally formed on the lower outer side of the push rod 2 is the key transmission structure for realizing the opening and closing action of the clamping mouth. The mold clamping block 5a, which is detachably connected to the bottom of the push rod 2 by a thread, can be replaced according to the specifications of the button to be clamped, ensuring stable clamping of different buttons. The buckle groove 41 opened at the front between the first clamping mouth 4a and the second clamping mouth 4b is adapted to the outer dimensions of the button to be clamped, providing guidance and initial positioning for the automated conveying of the button.

[0023] The first clamp 4a is axially rotatably connected to the left mounting wing 31a via a shaft pin 42, and the second clamp 4b is axially rotatably connected to the right mounting wing 31b via a shaft pin 42. Slots 43 are provided on the top of both the first clamp 4a and the top of the second clamp 4b. Metal springs 44 are symmetrically arranged on the left and right sides of the base block 3. The metal springs 44 are fastened to the base block 3 with bolts, and the end of the metal spring 44 furthest from the base block 3 is inserted into the slots 43 of the first clamp 4a and the second clamp 4b respectively. The metal springs 44 are in a pre-compressed state. The slots 43 on the top of the clamping mouth 4a and the second clamping mouth 4b are used to form a stable assembly fit with the metal spring 44. The metal spring 44, which is symmetrically arranged on the left and right sides of the base block 3, is fastened to the base block 3 by bolts. The end of the spring 44 away from the base block 3 is inserted into the slot 43 of the two clamping mouths. The metal spring 44 is always in a pre-compression state after assembly. This pre-compression setting enables the metal spring 44 to continuously apply an elastic clamping force towards the center of the first clamping mouth 4a and the second clamping mouth 4b, ensuring that the two clamping mouths can remain closed when there is no external thrust.

[0024] A through groove 45 is formed in the middle of the first clamp 4a and the second clamp 4b. The inner diameter of the through groove 45 matches the outer diameter of the push rod 2. The push rod 2 is movably inserted into the through groove 45. The inner wall of the first clamp 4a above the through groove 45 and the inner wall of the second clamp 4b above the through groove 45 are both provided with inclined slopes 46. The inclination angle of the inclined slopes 46 matches the inclination angle of the outer ramp block 21 of the push rod 2. The through groove 45 provides the necessary assembly space for the power transmission between the push rod 2 and the clamps. The inclined slope 46 on the inner wall above the through groove 45 is provided with the nozzle 4a and the second clamping nozzle 4b. The inclination angle of the slope 46 matches the inclination angle of the outer inclined block 21 of the push rod 2. When the push rod 2 moves downward under the drive of the main cylinder 1, the inclined block 21 will abut against the inclined slope 46. At this time, the vertical downward thrust of the push rod 2 will be converted into a lateral force that drives the two clamping nozzles to rotate around the shaft pin 42 through the inclined surface cooperation of the inclined block 21 and the inclined slope 46. This lateral force can overcome the elastic clamping force of the metal spring 44 and push the two clamping nozzles to open outward.

[0025] A fastening hole 4a1 is provided on the lower rear side of the first clamping mouth 4a, and a fastening bolt 4a2 is inserted into the fastening hole 4a1. The first clamping mouth 4a is detachably connected to a top buckle limiting block 5b through the fastening bolt 4a2. A groove 5b1 adapted to the buckle to be fastened is provided on the top of the top buckle limiting block 5b. The left side of the groove 5b1 is a closed structure and the right side is an open structure. The buckle can slide out from the right side of the groove 5b1. The bottom surface of the buckle groove 41 at the front between the first clamping mouth 4a and the second clamping mouth 4b is flush with the ground. The top surface of the top buckle limiting block 5b is adapted to the top surface of the top buckle limiting block 5b. The groove 5b1, which is adapted to the buckle to be fastened, is opened directly above the top buckle limiting block 5b. It can position the buckle that is transported to the processing position and ensure that the buckle will not shift horizontally during the buckling process. The design of the groove 5b1 with a closed structure on the left and an open structure on the right not only restricts the left displacement of the buckle by the closed structure on the left to ensure the positioning accuracy of the buckle, but also allows the buckle to slide out smoothly along the open structure on the right when the clamp opens.

[0026] The push rod 2 also includes a movable rod 22 and a force-applying spring 23. A movable cavity 24 is formed inside the push rod 2 along its own axial direction. The movable rod 22 is vertically positioned within the movable cavity 24. The force-applying spring 23 is located within the movable cavity 24 and directly above the movable rod 22. One end of the force-applying spring 23 abuts against the top of the movable cavity 24, and the other end abuts against the top of the movable rod 22, consistently applying a downward elastic force along the axial direction of the movable cavity 24 to the movable rod 22. A mutually cooperating limiting structure is provided between the movable rod 22 and the push rod 2. The movable cavity 24 inside the push rod 2 provides installation space for the movable rod 22 and the force-applying spring 23. The movable rod 22 is vertically positioned within the movable cavity 24, and a mutually cooperating limiting structure is provided between the movable rod 22 and the push rod 2. This limiting structure can... The force spring 23, which limits the travel of the movable rod 22, is located inside the movable cavity 24 and directly above the movable rod 22. Its two ends abut against the top of the movable cavity 24 and the top of the movable rod 22, respectively. In the non-working state and during the working process, the force spring 23 always applies an elastic force downward along the axial direction of the movable cavity 24 to the movable rod 22. When the mold block 5a at the bottom of the movable rod 22 contacts the button to be fastened, the elastic force of the force spring 23 can make the mold block 5a apply a pre-pressure to the button, ensuring that the button can be stably locked into the mold block 5a and preventing the button from falling off during subsequent movement. At the same time, the elastic characteristics of the force spring 23 can buffer the rigid impact force when the push rod 2 moves down, preventing the mold block 5a, the top buckle limiting block 5b and the button from being damaged by hard collision, thus extending the service life of the device components.

[0027] The bottom end of the movable rod 22 is provided with a threaded groove 221. Different specifications of mold clamping blocks 5a can be detachably installed in the threaded groove 221 through threaded engagement. The concave threaded groove 221 at the bottom end of the movable rod 22 adopts a standard thread structure design, which can form a threaded engagement with the external thread of the mold clamping blocks 5a of different specifications. The mold clamping blocks 5a and the movable rod 22 can be detachably assembled through threaded connection. The replacement of mold clamping blocks 5a can be completed without the need for complicated tools. When it is necessary to process different specifications and types of buttons, simply unscrew the original mold clamping block 5a and replace it with a new mold clamping block 5a that is compatible with the button to be made, which shortens the specification switching time of the device.

[0028] Working principle of the device and explanation of the function of the force spring: Initially, push rod 2 is at the top of the device. The automated conveying equipment transports the button to be fastened through the button slot 41 to the top button limiting block 5b, so that the button is fitted and positioned in the groove 5b1 of the top button limiting block 5b. After the button is positioned, the main cylinder 1 starts and drives push rod 2 to move downward vertically. During the downward movement of push rod 2, the mold locking block 5a at the bottom of its internal movable rod 22 first contacts the button. As push rod 2 continues to move downward, the force spring 23 above the movable rod 22 is compressed. At this time, the force spring 23, on the one hand, ensures that the button is stably locked into the mold locking block 5a by continuously applying downward elastic force, preventing the button from shifting or falling off in subsequent actions. On the other hand, the force spring 23 can buffer the downward movement of push rod 2. The rigid impact force during the movement prevents damage to components such as the mold clamping block 5a and the top buckle limiting block 5b due to rigid collision, extending the overall service life of the device. After the buckle is securely engaged, the push rod 2 continues to move downward, and its outer integrally formed ramp block 21 contacts the inclined slope surface 46 of the first clamp 4a and the second clamp 4b, converting the vertical downward pushing force of the push rod 2 into a lateral force, pushing the first clamp 4a and the second clamp 4b to overcome the elastic clamping force of the metal spring 44 and open outward. Since the top buckle limiting block 5b is installed on the first clamp 4a, as the first clamp 4a and the second clamp 4b open, the buckle can smoothly slide out along the right open structure of the groove 5b1 of the top buckle limiting block 5b and maintain a stable posture. Finally, the push rod 2 drives the mold clamping block 5a and the buckle to continue to move downward, completing the final buckling action.

[0029] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
