Description

Technical Field

[0001] This utility model relates to the field of spring sofa technology, specifically to a bag spring inserting and welding device. Background Technology

[0002] The production of pocket springs requires a pocket spring insertion and welding mechanism.

[0003] Existing bag spring welding mechanisms typically involve setting a clamping plate behind the welding mechanism, and then the welding mechanism moves back and forth and opens and closes synchronously with the clamping plate to pull the spring located at the end of the conveying mechanism out of the conveying mechanism, and then the welding mechanism welds the bag spring.

[0004] However, this method has the following problems: after the spring is pulled out from the conveying mechanism, the spring is in a completely free state inside the bag. At this time, the spring may move freely to the welding position of the welding mechanism when the clamp and welding mechanism release the bag, which may cause the spring to collide with the welding mechanism, resulting in scrap or machine damage.

[0005] Therefore, a spring-loaded bag welding device that can avoid this situation is proposed here. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the present invention aims to provide a bag spring insertion welding device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A bag-mounted spring insertion and welding device includes a conveying mechanism, a cloth bag, a welding mechanism, and a first clamping spring plate; The conveying mechanism is used to convey springs along a first direction; The bag at least partially encloses the conveying mechanism so that the spring conveyed by the conveying mechanism enters the bag; A welding mechanism, located at the output end of the conveying mechanism, is used to weld the cloth bag to form a bag spring; The welding mechanism has at least two first spring plates arranged opposite each other along the second direction. The two first spring plates can be opened and closed independently and displaced along the first direction to transfer the spring located in the bag at the output end of the conveying mechanism to the outside of the conveying mechanism. After the first clamping spring plate transfers the spring inside the bag from the conveying mechanism, the welding mechanism welds the bag to form a bag spring. The welding mechanism can move synchronously with the first clamping spring plate along the first direction.

[0008] Furthermore, it also includes a second spring plate, at least two of which are arranged opposite each other along a second direction in front of the first spring plate. The two second spring plates can open and close independently or synchronously with the first spring plate and can be displaced along the conveying direction of the conveying mechanism. The second spring plates are used to maintain the distance between the spring transferred by the first spring plate and the front bag spring.

[0009] Furthermore, the welding mechanism includes a welding knife and a die, which can be opened and closed independently in a second direction for welding and sealing the cloth bag to form a bag spring.

[0010] Furthermore, the conveying mechanism is a clamping conveyor belt / clamping conveyor chain.

[0011] Furthermore, the distance between the first clamping spring plate and the second clamping spring plate is adjustable.

[0012] Furthermore, the first clamping spring plate and the second clamping spring plate move synchronously along the first direction.

[0013] This utility model has the following beneficial effects: This utility model discloses a bag-mounted spring welding device. By setting a first clamping spring plate, the spring is clamped and pushed out by the first clamping spring plate each time it is output from the conveying mechanism, thereby effectively avoiding the spring from springing backward displacement when leaving the conveying mechanism. At the same time, the first clamping spring plate is located in front of the welding mechanism, which can limit the position of the spring and avoid affecting the welding action of the welding mechanism.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0016] like Figures 1-6 The present invention discloses a bag spring insertion and welding device, which includes a conveying mechanism 1, a cloth bag 2, a welding mechanism 3, and a first clamping spring plate 4. The conveying mechanism 1 is used to convey springs along a first direction; The cloth bag 2 at least partially encloses the conveying mechanism 1 so that the spring conveyed by the conveying mechanism 1 enters the cloth bag; Welding mechanism 3, located at the output end of conveying mechanism 1, is used to weld cloth bag 2 to form bag spring; The welding mechanism 3 has at least two first spring plates 4 arranged opposite each other along the second direction. The two first spring plates 4 can be opened and closed independently and displaced along the first direction to transfer the spring located in the bag at the output end of the conveying mechanism 1 to the outside of the conveying mechanism 1. After the first clamping spring plate 4 transfers the spring in the bag 2 from the conveying mechanism 1, the welding mechanism 3 welds the bag 1 to form a bag spring. The welding mechanism 4 can move synchronously with the first clamping spring plate along the first direction.

[0017] It should be noted that, generally, a support plate (not shown in the figure) is also provided on the outside of the conveying mechanism 1 to support the cloth bag 2, so as to ensure that the cloth bag 2 can maintain the bag opening shape. This is a common known technology in the art and will not be described in detail here.

[0018] It should be noted that the spring extends at least partially from the conveying mechanism 1 and the support plate along the first direction, thereby facilitating the deformation of the bag 2 to limit the spring inside the bag 2, and the deformation of the bag 2 can also push the spring.

[0019] It should be noted that the front of the welding mechanism 3 is provided with at least two first spring plates 4 arranged opposite each other along the second direction. The front of the first spring plates 4 is the front along the conveying direction of the conveying mechanism. Taking the already welded bag spring and the spring located at the output end of the conveying mechanism as references, the welded bag spring is located in front of the spring at the output end of the conveying mechanism.

[0020] It should be noted that each set of clamping rods has at least two rods, and each set of clamping rods is arranged along the first direction; at least two sets of clamping rods are provided that are arranged vertically opposite each other.

[0021] It should be noted that, in the specific embodiments of this utility model, the first direction is the front-back direction, the second direction is the up-down direction, and the third direction is the left-right direction.

[0022] Furthermore, the first clamping spring plate 4 and the welding mechanism 3 move synchronously along the first direction. After the first clamping spring plate 4 transfers the spring to a designated position outside the conveying mechanism 1, the welding mechanism welds the cloth bag 2 to form a bag spring.

[0023] In use, the welding mechanism 3 and the first spring clamping plate 4 are synchronously displaced along the first direction to a position so that the first spring clamping plate 4 corresponds to the spring located at the output end of the conveying mechanism 1. Then, the two first spring clamping plates 3 are independently closed along the second direction so that the first spring clamping plate 4 can directly or indirectly limit the spring through the bag 2. Then, the first spring clamping plate 4 is displaced along the first direction to drive the spring away from the conveying mechanism 1 to a designated position. At this time, the position of the welding mechanism 3 is directly opposite the position of the bag to be welded. Then, the welding mechanism 3 clamps and welds the bag 2 at the designated position, thus completing the production of a bag spring. Then, the welding mechanism 3 is released from the first spring clamping plate 4.

[0024] It should be noted that the first clamping spring plate 4 can be released after the welding mechanism 3 has finished clamping, or it can be released simultaneously with the welding mechanism 3, or it can be released in advance after the first clamping spring plate 4 pushes the spring to the designated position, and then the welding mechanism clamps and welds the cloth bag 2.

[0025] The advantages of this utility model are: 1. By setting the first clamping spring plate 4, the spring is clamped and pushed out by the first clamping spring plate 4 each time it is output from the conveying mechanism 1, thereby effectively avoiding the spring from springing backward displacement when it leaves the conveying mechanism 1. At the same time, the first clamping spring plate 4 is located in front of the welding mechanism, which can limit the position of the spring and avoid affecting the welding action of the welding mechanism.

[0026] Furthermore, it also includes a second spring plate 5, at least two of which are arranged opposite each other along a second direction in front of the first spring plate 4. The two second spring plates 5 can open and close independently or synchronously with the first spring plate 4 and can be displaced along the conveying direction of the conveying mechanism 1. The second spring plates 5 are used to maintain the distance between the spring transferred by the first spring plate 4 and the front pocket spring.

[0027] More preferably, by providing a second spring clamping plate 5, the distance between the spring and the bag spring in front is maintained during the process of the first spring clamping plate 4 transferring the spring from the conveying mechanism, which effectively facilitates subsequent machine processes such as counting and dividing.

[0028] It should be noted that the distance between the second spring plate 5 and the first spring plate 4 is adjustable, thus accommodating pocket springs with different spacing.

[0029] Furthermore, the welding mechanism 3 includes a welding knife 31 and a die 32, which can be opened and closed independently in the second direction for welding and sealing the cloth bag 2 to form a bag spring.

[0030] More preferably, the welding knife 31 is an ultrasonic welding knife.

[0031] Furthermore, the conveying mechanism 1 is a clamping conveyor belt / clamping conveyor chain.

[0032] More preferably, the conveying mechanism 1 is a clamping conveyor belt / clamping conveyor chain. The conveyor belt and conveyor chain have the advantages of stable and fast conveying, which is beneficial for conveying the spring to the designated position.

[0033] Furthermore, the second spring plate 5 and the first spring plate 4 are moved synchronously along the first direction to ensure that the distance between the second spring plate 5 and the first spring plate 4 remains unchanged, thereby ensuring that the distance between the bag spring in front and the spring behind remains unchanged.

[0034] More specifically, the first clamping spring plate 4 and the second clamping spring plate 5 can either move synchronously along the first direction or move independently along the first direction.

[0035] It should be noted that the displacement of the first spring plate 4, the second spring plate 5, and the welding mechanism 3 along the first and second directions is achieved by connecting to an external drive. The external drive can be a linear drive mechanism such as a cylinder or a ball screw, or other drive devices, as long as it can drive the first spring plate 4, the second spring plate 5, and the welding mechanism 3 to move along the first and second directions.

[0036] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
