Description

Technical Field

[0001] This utility model relates to the field of bag spring production machinery technology, specifically to a bag welding mechanism applied to the production of high-compression bag springs. Background Technology

[0002] The production of high-compression bagged springs requires a bagged spring insertion and welding mechanism.

[0003] Existing high-compression 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: When the spring is pulled out of the conveying mechanism via the clamp and the welding mechanism and clamp are released at the same time, the spring is in a completely free state inside the bag. Since the weld is formed in front and the other side is completely free, the spring will obviously receive the deformation force of the non-woven fabric at the weld and rebound, or tilt and misalign under the combined action of the bag and gravity. This can easily cause the spring to shift inside the bag, causing the spring to enter the original welding position of the bag, thus producing scrap. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model aims to provide a bag-feeding welding mechanism applicable to the production of high-compression bag springs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A bag-feeding welding mechanism for the production of high-compression bag springs includes a conveying mechanism, a cloth bag, a welding mechanism, a scraper, and a clamping rod; A conveying mechanism for clamping the spring in a third direction and conveying the spring in a first direction; The bag also includes support plates, the bag at least partially enclosing the conveying mechanism such that the spring conveyed by the conveying mechanism enters the bag, and the two support plates are arranged opposite each other along a third direction to at least support the bag and maintain the shape of the bag opening; A welding mechanism, located at the output end of a conveying mechanism or support plate, is used to weld and seal the cloth bag to form a weld seam in order to produce bag springs. Two scrapers are arranged opposite each other along the second direction. The two scrapers open and close synchronously along the second direction and move synchronously along the first direction with the welding mechanism. The scrapers can transfer the spring located at the output end of the output mechanism or the support plate away from the output mechanism or the support plate. Clamping rods, two sets of clamping rods are arranged opposite each other along the second direction and are located on the outside of the bag. The two sets of clamping rods can open and close along the second direction and can move along the first direction. Each set of clamping rods has at least two clamping rods. The two sets of clamping rods cooperate to limit the bag so that the bag forms at least one limiting space that limits the position of the spring. The welding mechanism, scraper, and clamping rod work together such that the spring that leaves the output mechanism or support plate is located within the limiting space formed on the cloth bag by the welding mechanism and scraper, or the weld and clamping rod, or the weld and welding mechanism.

[0007] Furthermore, at least partially, the two support plates extend beyond the conveying mechanism along the first direction, the clamping rod is capable of transferring the spring from the output mechanism to between the two support plates along the first direction, and the scraper, after closing, displaces along the first direction to transfer the spring from between the two support plates to outside the two support plates.

[0008] Furthermore, the scraper is provided with a through groove for the clamping rod to pass through.

[0009] Furthermore, one end of the clamping rod is suspended, allowing the clamping rod to pass through the through groove of the scraper.

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

[0011] Furthermore, the spacing between the two support plates is adjustable.

[0012] This utility model has the following beneficial effects: This utility model discloses a bag-feeding welding mechanism for the production of high-compression bag springs. By setting up a welding mechanism, scraper and clamping rod, the spring is limited by a limiting space composed of the weld, welding mechanism, scraper and clamping rod during the process of leaving the output mechanism or support plate, which effectively avoids the spring from rebounding backward or deviating vertically during release.

Detailed Implementation

[0014] 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.

[0015] like Figures 1-12 The present invention provides a bag-feeding welding mechanism for the production of high-compression bag springs, comprising a conveying mechanism 1, a cloth bag 2, a welding mechanism 3, a scraper 4, and a clamping rod 5. Conveying mechanism 1 is used to clamp the spring in a third direction and convey the spring in a first direction; The cloth bag 2 also includes a support plate 21. 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 2. The two support plates 21 are arranged opposite each other along a third direction to at least support the cloth bag 2 and maintain the shape of the bag opening. Welding mechanism 3, located at the output end of conveying mechanism 1 or support plate 21, is used to weld and seal the cloth bag 2 to form a weld seam to produce bag springs. Two scrapers 4 are arranged opposite each other along the second direction. The two scrapers 4 and the welding mechanism 3 open and close synchronously along the second direction and move synchronously along the first direction. The scrapers 4 can transfer the spring located at the output end of the output mechanism 1 or the support plate 21 away from the output mechanism 1 or the support plate 21. Clamping rods 5, two sets of clamping rods 5 are arranged opposite each other along the second direction and are located on the outside of the cloth bag 2. The two sets of clamping rods 5 can open and close along the second direction and can move along the first direction. The number of clamping rods 5 in each set is at least two. The two sets of clamping rods 5 cooperate to limit the cloth bag 2 so that the cloth bag 2 forms at least one limiting space 101 that limits the position of the spring. The welding mechanism 3, scraper 4, and clamping rod 5 cooperate to ensure that the spring that leaves the output mechanism 1 or support plate 21 is located within the limiting space 101 formed on the cloth bag 2 by the welding mechanism 3 and scraper 4, or the weld and clamping rod 5, or the weld and welding mechanism 3.

[0016] It should be noted that the spring extends at least partially from the conveying mechanism and the support plate 21 along the first direction, thereby facilitating the deformation of the bag 2 to limit the spring inside the bag 2.

[0017] It should be noted that in this utility model Figures 1-12 In the embodiment shown, 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.

[0018] like Figures 4-10 In the illustrated embodiment, the support plate 21 extends beyond the conveying mechanism 1 along the first direction. In this embodiment, when the present invention is used, the welding mechanism 3 releases the cloth bag 2 after completing the welding of the previous bag spring. At this time, the scraper 4 simultaneously releases the cloth bag 2. The spring waiting to be produced has already left the support plate 21 and is located within the limiting space 101 formed by the weld and the clamping rod 5 at the cloth bag 2 (e.g., Figure 4 As shown), the welding mechanism 3 and the scraper 4 then move synchronously to the position corresponding to the spring production location. Specifically, the welding mechanism 3 is positioned directly above the cloth bag 2 to be welded, and the scraper reaches the next spring position at the support plate 21 to be transferred (as shown). Figure 5 As shown), then the welding mechanism 3 and the scraper 4 move synchronously along the second direction to clamp the cloth bag 2. At this time, the spring waiting to be produced is located in the limiting space formed by the weld and the welding mechanism 3 at the cloth bag 2 (as shown). Figure 6 (As shown), then the clamping rod 5 releases the bag, at which point the next spring located in the support plate 21 is located in the limiting space 101 formed by the welding mechanism and scraper at the bag 2 (as shown). Figure 7 As shown), the clamping rod 5 then moves to the position of the next spring (as shown). Figure 8 (As shown), then the clamping rods 5 are relatively closed to limit the bag 2 to form a limiting space 101, and then the next spring is located in the limiting space 101 (as shown). Figure 9 (As shown), then the welding mechanism 3, scraper 4, and clamping rod 5 simultaneously move along the first direction, causing the spring waiting to be welded to leave the position waiting to be welded, the next spring leaves the space between the two support plates 21 and enters the position waiting to be welded, and the next spring enters the space between the two support plates 21 (as shown). Figure 10 As shown), in Figures 6-10 During the process, the welding mechanism 3 can weld the bag 2 while holding it in place; by repeating this process, the spring can be continuously welded into the bag to form a bag spring.

[0019] It needs to be further explained that, such as Figures 4-10 In the embodiment shown, during the process of the spring being transferred from the conveying mechanism 1 to the support plate 21, when the spring is released at the support plate 21, it is limited by the limiting space formed by the two clamping rods 5, thereby effectively preventing the spring from bouncing backward or deviating vertically during the release process.

[0020] It should be noted that, as Figure 4 As shown, after the welding mechanism 3 completes the welding of the previous bag spring, it releases the cloth bag 2. At this time, the scraper 4 releases the cloth bag 2 simultaneously. When the spring waiting to be produced has left the support plate 21 and is located in the limiting space 101 formed by the weld and the clamping rod 5 at the cloth bag 2, the spring is obviously subjected to the deformation force of the cloth bag 2 limited by the clamping rod 5 and is held in the position of the limiting space 101 formed by the clamping rod 5 and the weld.

[0021] Similarly, such as Figures 1-10 In the illustrated embodiment, the scraper and clamping rod can both directly or indirectly push the spring to move through the deformation force, thereby transferring the spring out of the conveying mechanism 1 or the support plate 21.

[0022] The scraper can also act directly on the spring located in the bag 2, thereby limiting and pushing the position of the spring inside the bag 2.

[0023] like Figures 11-12 In the embodiment shown, the support plate 21 does not extend beyond the conveying mechanism 1 in the first direction. At this time, the spring does not need to wait for transfer at the support plate 21. However, the specific action is similar to the above-mentioned action, except that the spring is directly transferred from inside the conveying mechanism 1 to outside the conveying mechanism 1 without having to go through the support plate 21. This will not be described in detail here.

[0024] The advantages of this utility model are: by setting up a welding mechanism, a scraper and a clamping rod, the spring is limited by the limiting space composed of the weld, welding mechanism, scraper and clamping rod during the process of leaving the output mechanism or support plate, which effectively avoids the possibility of the spring rebounding backward or deviating up and down when released.

[0025] Furthermore, the two support plates 21 extend at least partially beyond the conveying mechanism 1 along the first direction, the clamping rod 5 is able to transfer the spring from the output mechanism 1 to between the two support plates 21 along the first direction, and the scraper 4, after closing, displaces along the first direction to transfer the spring from between the two support plates to outside the two support plates 21.

[0026] Preferably, such as Figures 1-10 In the embodiment shown, by setting a support plate 21 that extends beyond the output mechanism 1, the high-compression spring is released for the first time when it enters the support plate 21 from the output mechanism 1, and then released for the second time when it leaves the support plate 21, thus dividing the release into two segments and avoiding excessive release at once.

[0027] like Figures 11-12 As shown, the scraper 4 is provided with a through groove for the clamping rod 5 to pass through.

[0028] It should be noted that by setting the through groove, the relative displacement of the scraper 4 and the clamping rod 5 will not cause collision.

[0029] Furthermore, one end of the clamping rod 5 is suspended, allowing the clamping rod to pass through the through groove of the scraper 4.

[0030] More preferably, in one embodiment of the present invention, one end of the clamping rod 5 is suspended and the other end of the scraper 4 is suspended, so that the scraper 4 and the clamping rod 5 are further misaligned, which is beneficial to ensure that their relative displacement is not affected.

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

[0032] More specifically, the clamping conveyor belt / clamping conveyor chain has the advantages of stable and fast conveying, and can be started and stopped at will, which is conducive to gradually coordinating the input of springs into the cloth bag 2.

[0033] 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.
