DETAILED DESCRIPTION

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0049] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0050] 1 , the present invention provides a chain belt production device, comprising: a frame body 1;

[0051] The sewing tool is provided at one end of the frame body 1, and the sewing tool is provided for the chain teeth 2 and the cloth tape 3 to pass through, ensuring that the chain teeth 2 and the cloth tape 3 maintain corresponding positions; the sewing machine is provided at the outside of the frame body 1, and the sewing machine sews the chain teeth 2 and the cloth tape 3 through the sewing area of ​​the sewing tool to form a chain tape; the chain tooth driving unit is provided at the other end of the frame body 1, and the chain tooth driving unit is used to drive the chain teeth 2 to move toward the sewing tool. It can be understood that the chain tooth driving unit realizes feeding the chain teeth 2 entering the sewing tool; the chain belt driving unit is provided on the outside of the frame body 1, and the chain belt driving unit drives the chain belt to move in a direction away from the sewing tool. It can be understood that the chain belt driving unit realizes that the chain teeth 2 and the cloth tape 3 continuously pass through the sewing tool to form a coded chain belt.

[0052] Specifically, the frame body 1 is used to support and fix related components; the sewing tool is set at one end of the frame body 1, which allows the head end of the chain tooth 2 and the head end of the cloth tape 3 to pass through, ensuring that the two maintain the correct corresponding positions during the sewing process.

[0053] The sewing machine is located outside the frame body 1 and sews the chain elements 2 and the cloth tape 3 through the sewing area of ​​the sewing tool to form a coded chain tape.

[0054] The chain tooth drive unit is arranged at the other end of the frame body 1, and its function is to drive the chain tooth 2 to move toward the sewing tooling so as to be sewn with the cloth tape 3; the chain belt drive unit is arranged on the outside of the frame body 1, and its function is to drive the sewn stacking chain belt to move in the direction away from the sewing tooling for collection.

[0055] That is to say, the chain belt production device provided in this application ensures that the chain teeth 2 and the cloth belt 3 maintain the correct relative position before sewing through sewing tooling, avoids the sewing line deviation phenomenon, and realizes precise feeding of the chain teeth 2 through the use of the chain tooth drive unit, thereby improving production efficiency.

[0056] Based on the above embodiment, the chain tooth drive unit includes a support plate 4, which is arranged on the frame body 1, and a driving member 5, which is arranged on the support plate 4; a driving wheel 6, which is arranged on the rotating shaft of the driving member 5, and the circumferential surface of the driving wheel 6 is provided with an annular groove, and the annular groove is used for two chain teeth 2 to pass through; an upper pressing mechanism, which is arranged on the support plate 4 and is located above the driving wheel 6, and the working end of the upper pressing mechanism is in contact with the upper end of the chain tooth 2 located in the annular groove.

[0057] Specifically, the support plate 4 is vertically arranged on the frame body 1 , so that the driving member 5 maintains a fixed position and angle relative to the frame body 1 .

[0058] The rotating shaft of the driving member 5 is connected to the driving wheel 6. The driving member 5 can be a motor. When the driving member 5 is started, it will drive the driving wheel 6 to rotate. The circumferential surface of the driving wheel 6 is provided with an annular groove. The annular groove can accommodate and drive two chain teeth 2 to pass through at the same time. The shape and size of the annular groove match the chain teeth 2 to ensure that the chain teeth 2 can remain stable and receive uniform driving force during the movement.

[0059] The working end of the upper pressure mechanism fits the upper end of the chain tooth 2 located in the annular groove, and is used to provide additional pressure when the chain tooth 2 is driven by the driving wheel 6 to ensure that the chain tooth 2 can fit tightly in the annular groove and move smoothly.

[0060] The end of the chain element 2 enters the annular groove of the drive wheel 6, and the driving member 5 is activated, driving the drive wheel 6 to rotate. The chain element 2 in the annular groove is driven by the driving force of the drive wheel 6 and begins to move in the direction of the sewing tool. At the same time, the working end of the upper pressure mechanism is attached to the upper end of the chain element 2, providing additional pressure to ensure that the chain element 2 can fit tightly in the annular groove and move smoothly, thereby achieving feeding.

[0061] Based on the above embodiment, the upper pressure mechanism includes a connecting shaft 7, which is arranged on the support plate 4, and the connecting shaft 7 is arranged parallel to the rotating shaft of the driving member 5; an upper pressure bracket 8, which is arranged on the connecting shaft 7; an upper pressure wheel 9, which is arranged on the upper pressure bracket 8, and the outer peripheral surface of the upper pressure wheel 9 can fit the upper end of the chain tooth 2 located in the annular groove, and the peripheral surface of the upper pressure wheel 9 is provided with an anti-slip structure.

[0062] Specifically, the connecting shaft 7 is fixedly connected to the support plate 4, the connecting shaft 7 is located above the driving member 5, and the upper pressure bracket 8 is rotatably connected to the connecting shaft 7, which is used to rotatably connect the upper pressure wheel 9, and then the upper pressure wheel 9 and the upper pressure bracket 8 can rely on gravity to make the outer peripheral surface of the upper pressure wheel 9 fit the upper end of the chain tooth 2 located in the annular groove of the driving wheel 6, providing the necessary pressure for the chain tooth to ensure that it remains stable during movement.

[0063] The circumferential surface of the upper pressure wheel 9 is provided with an anti-skid structure, such as an anti-skid groove, an anti-skid texture or a rubber coating, so as to increase the friction between the upper pressure wheel 9 and the chain teeth 2.

[0064] In summary, with the rotation of the driving wheel 6 and the pressure of the upper pressing wheel 9, the fastener elements 2 are stably transported to the position of the sewing tool.

[0065] Based on the above embodiment, the driving unit further includes a plurality of guide wheels 10, which are arranged on both sides of the frame body 1 and are used to guide the two chain elements 2 located on both sides of the frame body 1 through the sewing area of ​​the sewing tool.

[0066] That is, the guide wheel 10 guides the two chain teeth 2 located on both sides of the frame body 1, ensuring that the chain teeth 2 on both sides maintain the correct path and position during the movement process to avoid deviation or crossing.

[0067] The guide wheel 10 cooperates closely with the driving wheel 6 and the upper pressing mechanism to jointly ensure the stability and accuracy of the chain elements 2 during the conveying process.

[0068] Based on the above embodiment, the drive unit also includes a control mechanism for controlling the start and stop of the drive member, and the control mechanism includes: a connecting plate 11, which is arranged on both sides of the frame body 1; a connecting rod 12, which is rotatably connected to the two connecting plates 11; a movable bracket 13, which is symmetrically arranged at both ends of the connecting rod 12; a pressure wheel 14, which is arranged at the end of the two movable brackets 13, and the pressure wheel 14 is located below the adjacent guide wheel 10, and the two chain teeth 2 are attached to the lower end of the pressure wheel 14; a sensor, which monitors the rotation angle of the movable bracket 13, and the controller controls the start and stop of the drive member 5 according to the monitoring value.

[0069] That is to say, the connecting plates 11 are arranged on both sides of the frame body 1, the connecting rod 12 is rotatably connected to the two connecting plates 11, the movable brackets 13 are symmetrically arranged at both ends of the connecting rod 12, and the pressure wheel 14 is arranged at the ends of the two movable brackets 13, located below the adjacent guide wheel 10, so that the pressure wheel 14 is always pressed on the chain tooth 2 due to its own gravity.

[0070] Specifically, the chain tooth drive unit adopts an intermittent feeding method, that is, only a certain number of chain teeth are supplied each time for subsequent sewing.

[0071] When the feeding is completed, the driving member 5 (such as a motor) stops working, but the assembling chain (the chain carrying the chain teeth for sewing) continues to move to maintain the continuity of the sewing process. Due to the continuous movement of the assembling chain, the chain teeth 2 will drive the pressure wheel 14 to move upward, and the upward movement of the pressure wheel 14 further drives the movable bracket 13 to rotate clockwise around the connecting plate 11.

[0072] In order to prevent the interruption of the chain tooth feeding and the inability to complete sewing, the clockwise rotation angle of the movable bracket 13 is limited. When the movable bracket 13 rotates clockwise to the maximum angle, it means that the chain tooth supply is about to be exhausted. At this time, the trigger driving member 5 starts working again to achieve new feeding.

[0073] In order to prevent problems caused by excessive feeding (such as accumulation of chain teeth), a counterclockwise rotation angle limit is set for the movable bracket 13. When the movable bracket 13 rotates counterclockwise to the maximum angle, it means that the chain teeth supply is sufficient, and the system stops the operation of the driving part 5.

[0074] The sensor may be an angle sensor, such as a rotary encoder, for monitoring the rotation angle of the movable bracket 13 .

[0075] The rotary encoder is installed at the rotation connection between the movable bracket 13 and the connecting plate 11 to ensure that the rotation angle of the movable bracket 13 can be accurately measured. After the sensor is installed, necessary calibration is performed to ensure that the angle value measured by the sensor is consistent with the actual rotation angle of the movable bracket 13;

[0076] The sensor can also be a potentiometer, which is arranged at the end of the connecting rod 12. When the connecting rod rotates with the rotation of the movable bracket, the resistance value of the potentiometer will change. By reading the change in resistance value, the rotation angle of the connecting rod can be accurately measured, and the rotation angle of the movable bracket can be further inferred.

[0077] The signal measured by the sensor is transmitted to the control system (controller) via a cable or wirelessly for subsequent judgment and control. The maximum angle threshold for the clockwise and counterclockwise rotation of the movable bracket 13 is set in the control system; when the angle value monitored by the sensor reaches or exceeds the set threshold, the control system triggers the corresponding control logic. Based on the result of the judgment logic, the control system sends a start-stop signal to the driving member 5.

[0078] Based on the above embodiment, the sewing tool includes: a support block 15, which is arranged on the frame body 1, and a connecting block 16 is arranged at the upper end of the support block 15; a sewing structure, which is arranged on the connecting block 16 to ensure that the chain teeth 2 and the cloth tape 3 maintain corresponding positions for sewing during the sewing process.

[0079] On the basis of the above embodiment, the chain tooth sewing mechanism includes a limiting groove 17, which is symmetrically arranged on the connecting block 16. The corners of the limiting groove 17 are arc segments. The limiting groove 17 includes a long groove and a short groove. The long groove and the short groove form an L-shaped limiting groove 17. The long groove and the short groove both extend to the edge. The limiting groove 17 is used for the chain tooth 2 to pass through to constrain the horizontal and vertical movement positions of the chain tooth 2; a steel sheet 18 is arranged on the connecting block 16 and is located at the upper end of the short groove to constrain the vertical movement position of the chain tooth 2; a guide rod 19 is symmetrically arranged on the connecting block 16, and an isolation plate 20 is arranged between the two guide rods 19. Each cloth belt 3 is correspondingly located on each guide rod 19 ; The needle plate 21 is arranged on the connecting block 16, and two needle shuttle holes 22 are arranged on the needle plate 21, and each long groove corresponds to the needle shuttle hole 22 and is provided with a connecting channel; the cloth belt stopper 23 is arranged on the connecting block 16, and is symmetrically arranged on both sides of the needle plate 21 to limit the outer movement position of the two cloth belts 3; the cloth belt cover plate 24 is arranged on the connecting block 16 and is located above the needle plate 21. The bottom center line of the cloth belt cover plate 24 is provided with a separation plate 25, and the separation plate 25 limits the inner movement position of the two cloth belts 3. The cloth belt cover plate 24 limits the vertical movement position of the cloth belt 3, and two through holes 26 are provided on the cloth belt cover plate 24, and the through holes 26 are arranged corresponding to the needle shuttle hole 22.

[0080] Specifically, the limiting grooves 17 are symmetrically arranged on the connecting block 16 to accurately restrict the movement positions of the fastener elements 2 in the horizontal and vertical directions.

[0081] The limiting groove 17 consists of a long groove and a short groove, forming an L shape. Both the long groove and the short groove extend to the edge of the connecting block 16, which is convenient for the insertion and positioning of the chain teeth 2. The corners are designed as arc segments, with the long groove as the stitching area and the short groove as the chain tooth entry area. The chain tooth entry direction and the stitching drag chain direction are set to be perpendicular to each other, ensuring the stability of the chain tooth conveying position.

[0082] The steel sheet 18 is firmly set on the connecting block 16 at the upper end of the short slot, and is used to further constrain the vertical upward movement position of the chain element 2. The rigidity and stability of the steel sheet 18 ensure that the chain element 2 will not move upward due to external force during the sewing process.

[0083] The guide rods 19 are symmetrically arranged on the connecting block 16 to guide the transportation of the cloth tape 3. The isolation plate 20 is arranged between the two guide rods 19 to separate the two cloth tapes 3 to prevent mutual interference during the sewing process. Each cloth tape 3 is correspondingly located on a guide rod 19 to ensure that they can be smoothly transported to the sewing position.

[0084] The needle plate 21 is precisely set on the connecting block 16 for supporting the needle and performing sewing.

[0085] The needle shuttle hole 22 is cleverly set on the needle plate 21 for the up and down shuttle of the needle. Each long groove corresponds to a needle shuttle hole 22 and is provided with a connecting channel to ensure that the needle can smoothly pass through the chain teeth 2 and the cloth tape 3 for sewing.

[0086] The cloth tape stoppers 23 are symmetrically arranged on the connecting block 16 and located on both sides of the needle plate 21, and are used to limit the outer movement positions of the two cloth tapes 3 to prevent the cloth tapes 3 from shifting during the sewing process.

[0087] The tape cover 24 is securely mounted on the connecting block 16, above the needle plate 21. A separator plate 25 is located at the bottom centerline of the tape cover 24 to limit the inward movement of the two tapes 3. The tape cover 24 also limits the vertical upward movement of the tapes 3, ensuring they remain stably in the sewing position. The tape cover 24 is provided with two through-holes 26, corresponding to the needle shuttle holes 22, ensuring the needle can pass through the tapes 3 for sewing.

[0088] During the stitching process, the fastener element 2 is accurately conveyed into the limiting groove 17 and held in a precise position by the constraints of the long and short grooves. Simultaneously, the fabric tape 3 is conveyed onto the tape guide rod 19 and separated by the isolation plate 20. When both the fastener element 2 and the fabric tape 3 reach the stitching position, the needle passes through the needle shuttle hole 22 and the connected channel to sew the fastener element 2 and the fabric tape 3. The fabric tape stopper 23 and the fabric tape cover plate 24 jointly limit the movement of the fabric tape 3, ensuring the accuracy of stitching.

[0089] Based on the above embodiment, the belt guide rods 19 are diameter-reducing rods, and the outer diameters of the two belt guide rods 19 gradually decrease in the direction toward the isolation plate 20 .

[0090] That is to say, the outer diameter of the tape guide rod 19 gradually decreases from the end away from the isolation plate 20 in the direction toward the isolation plate 20, which helps to gradually tighten and position the cloth tape 3 during the transportation process, ensuring that the cloth tape 3 is in the best condition when in the sewing position.

[0091] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0092] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
