Description

Technical Field

[0001] This utility model relates to the field of tote bag processing technology, and in particular to a handle buckle transmission mechanism. Background Technology

[0002] The existing handle buckles include male and female buckles. The male and female buckles need to be transferred to the handbag position through a transmission mechanism, and the male and female buckles are fastened together and fixed on the handbag by a pressing mechanism.

[0003] The prior application CN202321787884.0 discloses a buckle feeding mechanism for tote bag processing, including an assembly frame with two opposing clamping plates on the assembly frame. The inner sides of the two clamping plates have clamping grooves adapted to the outer contour of the handle buckle. The assembly frame also includes a clamping assembly for driving the two clamping plates to clamp or loosen, and a conveying assembly for driving the clamping plates to slide back and forth. The clamping assembly includes a screw rotatably mounted on the assembly frame and a screw drive for driving the screw to rotate. The screw is threadedly engaged with at least one clamping plate to bring the two clamping plates together or separate. The rotation of the screw can drive the side plates to slide towards or away from each other, thereby clamping or loosening the handle buckle.

[0004] The problem with the aforementioned patent is that the conveying assembly controls the back-and-forth movement of two clamping plates to convey the handle buckle. The end points of the two clamping plates are usually equipped with a pressing mechanism, and a guide plate is provided between the two clamping plates. The handle buckle moves gradually along the path of the guide plate under the action of the clamping plates. During this transmission process, it is necessary to control the clamping force of the two clamping plates. If the clamping is too tight, the handle buckle will deform. If the clamping is too loose, the handle buckle at the end of the guide plate will fall off. Before the pressing process, the handle buckle needs to be separated from the end of the guide plate and reach the pressing mechanism. At this stage, the handle buckle is only fixed by the two clamping plates. If the clamping between the two clamping plates is too loose, the handle buckle will fall off directly. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a handle buckle transmission mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a handle buckle transmission mechanism, including an assembly frame, on which a guide plate and a feeding assembly are fixed. The feeding assembly includes clamping plates disposed opposite to each other on both sides of the guide plate. The two clamping plates are respectively provided with clamping grooves adapted to the outer contour shape of the handle buckle on one side close to each other. It also includes a clamping assembly for driving the two clamping plates to clamp or loosen, and a conveying assembly for driving the two clamping plates to slide along the front-back direction of the guide plate. At least one clamping plate has an actuator at its rear end. The actuator is a telescopic drive or a rotary drive. The output end of the actuator has a support portion that can be rotated or telescopically extended to the bottom of the handle buckle. The support portion is used to provide support below the handle buckle.

[0007] As a preferred technical solution of this utility model, each of the two clamping plates is provided with an actuator at the bottom of its rear end, and the position of the actuator corresponds to the clamping groove. When the two clamping plates are brought together, the support parts on both sides can be rotated or extended and retracted to below the handle buckle under the drive of the actuator.

[0008] As a preferred technical solution of this utility model, when the actuator is a telescopic drive member, the support part is set as a support plate with an arc opening, the arc opening faces the clamping groove side and the arc opening is adapted to the shape of the clamping groove, and the telescopic direction of the support plate is parallel to the opening and closing direction of the clamping plate.

[0009] As a preferred technical solution of this utility model, the feeding assembly is provided in two sets and the two sets of feeding assemblies are arranged at intervals along the longitudinal direction. Each set of feeding assemblies is provided with a guide plate. The upper and lower clamping plates on the two sides of the two sets of feeding assemblies are connected to realize that the two left and right opposite clamping plates of the two sets of feeding assemblies can be brought together or released at the same time. The clamping assembly drives one set of feeding assemblies to open and close, and the conveying assembly drives one set of feeding assemblies to slide along the front and rear direction of the guide plate. The rear end of the upper set of feeding assemblies is optionally equipped with an actuator.

[0010] As a preferred technical solution of this utility model, each of the guide plates is provided with a limiting plate fixed to the assembly frame at intervals above it, and a transportation channel is formed between the limiting plate and the guide plate.

[0011] As a preferred technical solution of this utility model, the assembly frame is provided with at least one gantry frame along the length of the guide plate, and the two sides of the guide plate are connected to the gantry frame by fixing rods.

[0012] As a preferred technical solution of this utility model, a movable seat is connected below the feeding assembly in the lower group. The movable seat cooperates with the assembly frame through a first guide structure. The conveying assembly includes a ball screw rotatably disposed on the assembly frame and a driving component that drives the ball screw to rotate. The ball screw is threadedly engaged with the movable seat.

[0013] As a preferred technical solution of this utility model, a second guide structure parallel to the opening and closing direction of the clamping plate is provided between the movable seat and the lower feeding assembly. The clamping assembly includes a forward and reverse thread adjusting screw rotatably disposed on the movable seat and a servo motor for driving the forward and reverse thread adjusting screw to rotate. The two clamping plates of the lower feeding assembly are respectively threadedly engaged with the forward and reverse thread adjusting screw.

[0014] As a preferred technical solution of this utility model, the assembly frame is provided with a pressing mechanism located at the rear end of the feeding component. The pressing mechanism includes a pressing mold and a top mold arranged in the longitudinal direction. The pressing mold and the top mold are respectively controlled to lift and lower by a drive unit, and are used to press the handle buckle onto the tote bag.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting an actuator and a retractable / rotatable support part at the rear end of the clamping plate, the support part can provide auxiliary support for the handle buckle from the bottom when the handle buckle is transmitted to the end of the guide plate, without the need to strictly control the clamping force. This design effectively solves the problem of handle buckle falling off or deforming due to insufficient or excessive clamping force of the clamping plate in traditional mechanisms, ensuring that the handle buckle can still maintain the correct position after it is removed from the guide plate, and avoiding falling off before the pressing process.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-4 The illustrated handle buckle conveying mechanism includes an assembly frame 1, on which a guide plate 2 (handle buckles 23 are placed on the guide plate 2 and the width of the handle buckles 23 is greater than the width of the guide plate 2) and a feeding assembly 3 are fixed. The feeding assembly 3 includes clamping plates 4 arranged opposite to each other on both sides of the guide plate 2. The two clamping plates 4 are respectively provided with clamping grooves 5 on one side close to each other, which are adapted to the outer contour shape of the handle buckles 23. The mechanism also includes a clamping assembly 6 for driving the two clamping plates 4 to clamp or loosen, and a conveying assembly for driving the two clamping plates 4 to slide along the front and back direction of the guide plate 2. Component 7, at least one clamping plate 4 has an actuator 8 at its rear end. The actuator 8 is a telescopic drive or a rotary drive. The output end of the actuator 8 has a support 9 that can be rotated or telescopically extended to the bottom of the handle buckle 23. The support 9 is used to provide support below the handle buckle 23. In this embodiment, the telescopic drive is a cylinder, electric cylinder, hydraulic cylinder, or servo motor that is threadedly engaged with the support (the support 9 is guided by the clamping plate 4 to achieve linear telescopic movement). The rotary drive is a servo motor, stepper motor, pneumatic rotary motor, or pneumatic swing cylinder.

[0024] By setting the actuator 8 and the telescopic / rotatable support 9 at the rear end of the clamping plate 4, the support 9 can provide auxiliary support for the handle buckle 23 from the bottom when it is transmitted to the end of the guide plate 2. There is no need to strictly control the clamping force. This design effectively solves the problem of handle buckle 23 falling off or deforming due to insufficient or excessive clamping force of the clamping plate 4 in traditional mechanisms. It ensures that handle buckle 23 can still maintain the correct position after it is separated from the guide plate 2, and avoids falling off before the pressing process.

[0025] Both clamping plates 4 have an actuator 8 at their rear bottom, and the position of the actuator 8 corresponds to the clamping groove 5. When the two clamping plates 4 are brought together, the support parts 9 on both sides can rotate or extend and retract to below the handle buckle 23 under the drive of the actuator 8. In this embodiment, the actuator 8 is a rotary drive. In the initial state, the support part 9 is parallel to the clamping plate 4. When the handle buckle 23 is delivered to the end, the drive controls the support part 9 to rotate 90°, so that it changes direction to below the handle buckle 23.

[0026] When the actuator 8 is a telescopic drive, the support part 9 is set as a support plate 10 with an arc 22. The arc 22 faces the clamping groove 5 and the shape of the arc 22 is adapted to the clamping groove 5. The telescopic direction of the support plate 10 is parallel to the opening and closing direction of the clamping plate 4. When the support plate 10 is not extended, the arc 22 and the clamping groove 5 are aligned or only partially misaligned.

[0027] The feeding assembly 3 has two sets, which are spaced apart along the longitudinal direction. Each set of feeding assemblies 3 is separated by a guide plate 2. The upper and lower clamping plates 4 on opposite sides of the two sets of feeding assemblies 3 are connected (i.e., connecting blocks or connecting rods are respectively provided between the upper and lower clamping plates 4 on both sides, with the ends of the connecting blocks or connecting rods welded to the clamping plates 4, or connected by fasteners). This allows the two left-right opposing clamping plates 4 of the two sets of feeding assemblies 3 to simultaneously close or open. The clamping assembly 6 drives one set of feeding assemblies 3 to open and close, and the conveying assembly 7 drives one set of feeding assemblies 3 to slide along the front-back direction of the guide plate 2. An actuator 8 is optionally installed at the rear end of the feeding assembly 3 above. The two feeding assemblies 3 are longitudinally spaced apart, and the upper and lower clamping plates 4 are opened and closed synchronously using a connecting rod and synchronous belt. The two feeding assemblies 3 simultaneously transmit the female buckle and the female buckle, shortening the single pressing cycle and greatly improving the production efficiency of the tote bag processing. In this embodiment, the clamping plate 4 reciprocates. The clamping plate 4 is provided with multiple clamping grooves 5 at intervals along its length. The clamping plate 4 moves one station (i.e., the position of one clamping groove) to the rear end each time and then resets. This process is repeated so that the handle buckles 23 can be conveyed one by one to the pressing mechanism 19. Each handle buckle 23 conveyed to the rear end corresponds to the clamping groove 5 of the clamping plate 4.

[0028] Each guide plate 2 is provided with a limiting plate 11 fixed to the assembly frame 1 at intervals above it, and a transport channel 12 is formed between the limiting plate 11 and the guide plate 2.

[0029] At least one gantry frame 13 is provided on the assembly frame 1 along the length of the guide plate 2, and the two sides of the guide plate 2 are connected to the gantry frame 13 by fixing rods 14.

[0030] Below the feeding assembly 3 in the lower group is a movable seat 15. The movable seat 15 cooperates with the assembly frame 1 through the first guide structure 16. The conveying assembly 7 includes a ball screw 18 rotatably mounted on the assembly frame 1 and a drive component (not shown in the figure) that drives the ball screw 18 to rotate. The drive component is a servo motor, stepper motor, etc. The ball screw 18 is threadedly engaged with the movable seat 15. In this embodiment, the first guide structure 16 adopts a slide rail and a slider cooperation. The slide rail is fixed on the assembly frame 1, and the slider is fixed on the bottom of the movable seat 15 to prevent the movable seat 15 from rotating when the ball screw 18 rotates. This is the prior art, so it is not described in detail.

[0031] A second guide structure 17, parallel to the opening and closing direction of the clamping plate 4, is provided between the upper surface of the movable seat 15 and the lower set of feeding components 3. The clamping component 6 includes a forward and reverse thread adjustment screw (parallel to the opening and closing direction of the clamping plate) rotatably mounted on the movable seat 15 and a servo motor that drives the forward and reverse thread adjustment screw to rotate. The two clamping plates 4 of the lower set of feeding components 3 are respectively threadedly engaged with the forward and reverse thread adjustment screw. The clamping component 6, driven by the forward and reverse thread adjustment screw and the servo motor, can precisely control the clamping force of the two clamping plates 4, avoiding excessive clamping force that could deform the handle buckle 23. Combined with the arc-shaped adaptation design of the clamping groove 5 and the support part 9, it can be compatible with the handle buckle 23 and improve the adaptability of clamping. In this embodiment, the second guide structure 17 adopts a slide rail and slider cooperation. The slide rail is fixed on the upper surface of the movable seat 15, and the slider is fixed on the bottom of the clamping plate 4. The two slide and cooperate. The structure of the clamping component 6 is existing technology and is relatively mature in the market, so the specific structure is not shown in the attached drawings.

[0032] The assembly frame 1 is equipped with a pressing mechanism 19 located at the rear end of the feeding assembly 3. The pressing mechanism 19 includes a pressing mold 20 and a top mold 21 arranged in the longitudinal direction. The pressing mold 20 and the top mold 21 are driven by a cylinder or a hydraulic cylinder, respectively. Alternatively, a servo motor can be used in conjunction with a screw drive to control the lifting of the pressing mold 20 or the top mold 21. The pressing mold 20 and the top mold 21 are threaded with the screw. The pressing mold 20 and the top mold 21 need to be guided (guide rail, slider structure) to achieve longitudinal sliding, which is used to press the handle buckle 23 onto the tote bag.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples of this utility model and are not intended to limit it. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
