Description

Technical Field

[0001] This utility model relates to the field of mattress manufacturing technology, and more specifically, to a bagged spring string feeding device. Background Technology

[0002] With social development and the improvement of living standards, people have increasingly higher requirements for the comfort of their home furnishings, such as using spring mattresses to improve bed comfort. Existing spring mattresses are mainly composed of several rows of pocket springs connected together. Pocket springs are generally formed by individually wrapping springs in non-woven fabric. Because the bonding speed of pocket spring strings is faster than the production speed, waiting time is required during the bonding process, leading to production interruptions and affecting production efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a bag spring string feeding device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a bag spring string feeding device, including two input mechanisms, which are arranged in a front-to-back manner. A first conveyor belt is arranged on the right side of the input mechanism. A cutting mechanism is arranged between the input mechanism and the first conveyor belt. A second conveyor belt is arranged between the two first conveyor belts. The second conveyor belt is inclined. A stop block is arranged at the lower end of the second conveyor belt. A pushing cylinder is arranged on the outer side of the first conveyor belt. The pushing cylinder is driven by a push rod.

[0006] Furthermore, the input mechanism includes a bottom conveyor belt, with side conveyor belts on both the front and rear sides of the bottom conveyor belt, and a pressure plate installed above the bottom conveyor belt.

[0007] Furthermore, the cutting mechanism includes a support rod, with a top plate connected to the upper end of the support rod. A lifting cylinder is installed on the top plate. A drive plate and a lifting plate are slidably arranged on the support rod. A connecting rod connects the drive plate and the lifting plate. The lifting cylinder drives the drive plate. A pressure block is installed at the lower part of the lifting plate. A moving mechanism is installed on the lifting plate. The moving mechanism drives the blade holder. A cutting blade is installed on the blade holder. A support platform is provided below the pressure block.

[0008] Furthermore, there are two pressure blocks, which are arranged along the length of the lifting plate. There is a gap between the two pressure blocks. The thickness of the knife holder and the cutter is less than the gap between the two pressure blocks, and the knife holder and the cutter can pass through the gap between the pressure blocks.

[0009] Furthermore, the lower part of the block is provided with several spikes.

[0010] Furthermore, the moving mechanism includes a lead screw cylinder, which drives a lead screw connected to it. A lead screw slider is mounted on the lead screw, and the upper end of the tool holder is connected to the lead screw slider.

[0011] Furthermore, an extension plate is installed on the side of conveyor belt one near conveyor belt two, with the end of one extension plate of conveyor belt one located above the upper end of conveyor belt two, and the end of the other extension plate of conveyor belt one located above the upper end of the stop block.

[0012] The beneficial effects of this utility model are: the bagged spring strings from both sides are alternately fed into the two points of the conveyor belt, which reduces the waiting time for the bagged spring strings to be fed, thereby speeding up the production efficiency.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-4As shown, a bagged spring string feeding device includes two input mechanisms 1, which are arranged opposite each other. A conveyor belt 2 is located on the right side of each input mechanism 1, and a second conveyor belt 10 is located between the two conveyor belts 2. A pushing cylinder 7 is located on the outer side of the first conveyor belt 2, and a push rod 8 is driven by the pushing cylinder 7 to push the bagged spring string on the first conveyor belt 2 into the second conveyor belt 10. A support plate 12 is located on the side of the second conveyor belt 10 away from the input mechanisms 1, and the support plate 12 supports the bagged spring string conveyed from the second conveyor belt 10.

[0020] The input mechanism 1 includes a bottom conveyor belt 4, with side conveyor belts 5 on both the front and rear sides of the bottom conveyor belt 4, and a pressure plate 6 installed above the bottom conveyor belt 4. The bottom conveyor belt 4 and the side conveyor belts 5 work together to effectively transport the bagged spring strings.

[0021] A pressure plate 6 is installed above the bottom conveyor belt 4. The pressure plate 6 is located above the moving bag spring string and limits its movement to prevent the bag spring from arching and causing blockage.

[0022] like Figure 4 As shown, conveyor belt 2 10 is inclined, and a stop block 11 is provided near the lower end of conveyor belt 2 10. The stop block 11 is perpendicular to the upper end face of conveyor belt 2 10. An extension plate 9 is installed on the side of conveyor belt 1 2 near conveyor belt 2 10. The end of one of the extension plates 9 of conveyor belt 1 2 is located above the upper end of conveyor belt 2 10. After the bag spring string on conveyor belt 1 2 is pushed off conveyor belt 1 2, the end falls on conveyor belt 2 10 and slides down the inclined conveyor belt 2 10 until the end abuts against the stop block 11, thus completing the transfer from conveyor belt 1 2 to conveyor belt 2 10. The end of the extension plate 9 of the other conveyor belt 2 is located above the upper end of the stop block 11. After the bag spring string on the conveyor belt 2 is pushed off the conveyor belt 2, its end also falls on the conveyor belt 2 10. As the rear end of the bag spring is continued to be pushed, the end of the bag spring will rise along the inclined conveyor belt 2 10. After the bag spring is pushed off the extension plate 9, the rear end of the bag spring will fall on the stop block 11, thus completing the transfer from the conveyor belt 2 to the conveyor belt 2 10.

[0023] The bagged spring strings on both sides of conveyor belt 2 fall alternately into conveyor belt 2 10 and are transported by conveyor belt 2 10 to the next process, which can reduce the waiting time for the production of bagged spring strings.

[0024] like Figure 2As shown, a cutting mechanism 3 is provided between the input mechanism 1 and the conveyor belt 2. The cutting mechanism 3 includes two support rods 13. The upper end of the support rod 13 is connected to a top plate 14. A lifting cylinder 15 is installed on the top plate 14. A drive plate 17 and a lifting plate 16 are slidably arranged on the support rods 13. A sliding sleeve is fitted on the support rods 13. The lifting plate 16 and the drive plate 17 are installed on the sliding sleeve. A connecting rod 18 connects the drive plate 17 and the lifting plate 16. The lifting cylinder 15 drives the drive plate 17. A pressure block 19 is installed at the lower part of the lifting plate 16. Several spikes 20 are provided at the lower part of the pressure block 19. A moving mechanism is installed on the lifting plate 16. The moving mechanism drives a knife holder 24. A cutter 25 is installed on the knife holder 24. The moving mechanism can drive the cutter 25 to move along the length of the lifting plate 16. A support platform 26 is provided below the pressure block 19, and an opening 27 is provided on the support platform 26 along the length of the lifting plate 16. When the lifting plate 16 moves down, the non-woven fabric contacts the upper surface of the support platform 26. Since the lower end of the cutter 25 can enter the opening 27, the side edge of the cutter 25 can contact the non-woven fabric, thereby obtaining a better cutting effect.

[0025] The lifting cylinder 15 drives the drive plate 17 to move downwards. The drive plate 17, through the connecting rod 18, drives the lifting plate 16 to move downwards, causing the spikes 20 at the bottom of the pressure block 19 to abut against the non-woven fabric of the bag spring. The spikes 20 then descend and contact the support table 26, thereby clamping and fixing the non-woven fabric. The moving mechanism drives the support table 26 to move, thereby cutting the non-woven fabric to obtain a bag spring string of the required length.

[0026] like Figure 3 As shown, two pressure blocks 19 are provided, which are arranged along the length of the lifting plate 16 and clamp the non-woven fabric from both sides at the cut point, preventing the non-woven fabric from moving and thus completing the cutting more effectively. A gap is left between the two pressure blocks 19, and the thickness of the knife holder 24 and the cutter 25 is less than the gap between the two pressure blocks 19, thereby ensuring that the knife holder 24 and the cutter 25 can pass through the gap between the pressure blocks 19 to complete the cutting process.

[0027] The moving mechanism includes a lead screw cylinder 21, which drives a lead screw 22. A lead screw slider 23 is mounted on the lead screw 22, and the upper end of the cutter holder 24 is connected to the lead screw slider 23. The lead screw cylinder 21 drives the lead screw 22 to rotate in both directions, thereby moving the lead screw slider 23 back and forth, allowing cutting to be completed in both directions.

[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
