Description

Technical Field

[0001] The utility model relates to the technical field of mattress machinery, in particular to a bed net production device. Background Art

[0002] Spring mattress is a commonly used furniture.

[0003] The existing spring mattress production is generally made by gluing multiple spring strips together. However, when the glued pocket spring strips are decomposed and recycled, the glue will pollute the environment, which is not in line with the current green and environmentally friendly ecological concept.

[0004] In order to comply with the concept of green production, there is a bed net combination device that realizes the welding positioning and displacement of the spring string by two sets of welding knives that alternately move up and down and forward and backward. At the same time, there is also a non-glue pocket spring bed core manufacturing device that uses a set of welding knives that can move forward and backward, up and down, and left and right to weld and position the spring string through a single set of welding knives.

[0005] However, both methods have disadvantages: the welding knife needs to move forward and backward, but the welding distance between the welding knife and the die head is constant. When the welding knife is too close or too far back and forth during resetting, it will cause discomfort between the welding knife and the die head.

[0006] In summary, the present utility model is proposed. Utility Model Content

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0036] like Figures 1 to 5The utility model is a bed net production device, comprising a feeding assembly 1, a die cutter assembly 2, a welding head assembly 3 and a displacement assembly 4;

[0037] The feeding assembly 1 is used to transport the spring string to a specified position;

[0038] The knife die assembly 2 is composed of more than one knife die 21 arranged in parallel along the left-right direction. The knife die assembly 2 can at least move up and down so that the knife die 21 is close to or away from the spring string, and the knife die 21 cannot move forward and backward;

[0039] The welding head assembly 3 is composed of more than one welding head 31 arranged in parallel along the left-right direction. The welding head assembly 3 can move up and down, left and right, and front and back. The welding head assembly 3 avoids the feeding assembly 1 by moving up and down. The welding head 31 corresponds to the knife die 21 one by one. The front and back displacement of the welding head assembly 3 enables the welding head 31 and the knife die 21 to be relatively close or away from each other to achieve welding;

[0040] The displacement assembly 4 is arranged behind the knife die assembly 3 and is used to convey the welded spring strings along the front-to-back direction.

[0041] It should be noted that a support plate is also arranged between the feeding assembly 1 and the displacement assembly 4 (the support plate can be arranged only below the spring string to support the spring, or can be arranged above and below the spring string to clamp the spring), and a slot corresponding to the cutting die 21 is opened on the support plate, and the slot is used to avoid the up and down displacement of the cutting die 21.

[0042] During specific use of the utility model, after completing one welding and lifting the cutting die assembly 2, when it is necessary to prepare for the welding of the next spring string, the displacement mechanism only needs to move the spring string forward to the cutting inserting area 103, and then the other set of cutting die assemblies 2 are moved up and down so that the cutting die 21 is inserted between the welded spring strings, and then the displacement mechanism 4 drives the spring string to continue to move forward so that the last row of spring strings reaches the welding area, so that the next row of spring strings can be prepared for feeding and welding.

[0043] The advantages of the utility model are as follows: 1. By setting a displacement component and a cutting die that does not need to be displaced forward and backward, each time the pocket spring is reinserted, it is only necessary to move the pocket spring through the displacement component, the action is simple, and the welding distance between the cutting die and the welding head can be kept the same; 2. Two sets of staggered cutting dies are set, so that the two sets of cutting dies only need to be displaced up and down alternately, the action is simple, and it is conducive to rapid production.

[0044] like Figures 1-2 In the illustrated embodiment, the displacement assembly 1 is composed of conveyor belts disposed opposite to each other up and down.

[0045] It should be noted that when the displacement assembly 1 is a conveyor belt that is opposite to each other up and down, when the spring string enters the welding area 101, the spring string at least partially enters the displacement assembly 1. At this time, the displacement assembly 1 can drive the spring string to move forward and backward.

[0046] Furthermore, the displacement assembly 1 is composed of two sets of parallel conveyor belts, which are arranged relatively up and down to clamp the conveying spring string up and down, and the knife die 21 rises and falls between the two adjacent conveyor belts on the left and right.

[0047] like Figure 3 In the embodiment shown, the displacement assembly 1 is composed of a plurality of conveyor belts opposed to each other up and down, and the cutting die is displaced up and down between two adjacent conveyor belts. When the spring string is laid on the cutting die, a part of the spring string must be clamped by the displacement assembly 1. At this time, the displacement assembly 1 can drive the spring string to move forward and backward.

[0048] like Figures 1 to 6 As shown in the embodiment, further, the knife die assembly 2 also includes a knife die lifting mechanism 22, two knife die lifting mechanisms 22 are staggered, and the two groups of knife dies are respectively installed on the two groups of knife die lifting mechanisms 22.

[0049] Furthermore, the knife die lifting mechanism 22 includes a knife die lifting frame 23 and a knife die driving device 24. The knife die lifting frame 23 is provided with a plurality of cantilevers 25. The knife die 21 is installed on the cantilever 25. The two knife die lifting frames 23 are arranged relative to each other so that the cantilevers 25 on the two knife dies 21 are staggered at intervals. The knife die driving device 24 is used to drive the knife die lifting frame 23 to move up and down.

[0050] It should be noted that the two die-cutting drive devices 24 both use at least one of a linear drive, a cylinder push mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0051] like Figures 1 to 6 As shown in the embodiment, the knife die driving devices 24 are driven up and down by a cylinder pushing mechanism, the cylinder is fixedly arranged, and each group of the knife die driving devices 24 are respectively installed on the piston rods of two cylinders through a mounting frame. The piston rods of the cylinders are telescopically driven to drive the corresponding knife die lifting frame 23 to move up and down, thereby realizing the up and down displacement of the two groups of knife dies 21 respectively.

[0052] More specifically, by providing the cantilever 25, it can be effectively ensured that the lifting and lowering of the two sets of cutting dies 21 do not affect each other.

[0053] Furthermore, the loading assembly 1 includes a loading displacement mechanism 11, a conveying mechanism 12 and a dial 13. The spring string is input through the conveying mechanism 12. The loading displacement mechanism drives the conveying mechanism 12 and the dial 13 to move left and right synchronously. The two dials 13 are arranged on both sides of the output end of the conveying mechanism 12 for clamping the spring for conveying.

[0054] More specifically, the conveying mechanism 12 is a clamping conveying mechanism, which is formed by conveying belts / conveying chains arranged relatively to each other and is used to stabilize the conveying spring.

[0055] More specifically, the two dials 13 clamp the springs for transportation, which can ensure that the springs transported via the dials 13 have equal spacing, which is beneficial for subsequent welding.

[0056] More specifically, the feeding displacement mechanism 11 can adopt at least one of a linear drive, a cylinder driving mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0057] like Figures 1 to 6 As shown in the embodiment, the feeding displacement mechanism 11 adopts a linear drive, and the conveying mechanism 12 and the dial 13 are both installed on the output end of the linear drive, so that the feeding mechanism 1 can be quickly displaced left and right, which is conducive to rapid feeding.

[0058] Furthermore, the dial 13 can be displaced in the front-rear direction.

[0059] As described in the embodiments of Figures 1 to 6, the dial 13 is mounted on a mounting frame, and the mounting frame can be driven by a cylinder to move away from or close to the output end of the conveying mechanism 12 in the front-to-back direction, so that the dial 13 can be displaced in the front-to-back direction.

[0060] It should be noted that the forward and backward displacement of the dial 13 can be achieved by at least one of a linear drive, a cylinder push mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0061] like Figures 1 to 6 In the embodiment shown, the front-rear displacement of the dial 13 is performed by a cylinder pushing mechanism, in which case the cylinder body of the cylinder is fixedly arranged, and the piston rod of the cylinder is connected to the mounting frame of the dial 13 .

[0062] Furthermore, the welding head assembly 3 also includes a welding head transverse movement mechanism 32, a welding head lifting mechanism 33 and a welding head longitudinal displacement mechanism 34. All of the welding heads 31 are installed on the welding head transverse movement mechanism 32 or the welding head lifting mechanism 33 or the welding head longitudinal displacement mechanism 34. The welding head transverse movement mechanism 32 is used to drive all of the welding heads 31 to synchronously move left and right, the welding head lifting mechanism 33 is used to drive all of the welding heads 31 to synchronously move up and down, and the longitudinal displacement mechanism 34 is used to drive all of the welding heads 31 to synchronously or independently move forward and backward.

[0063] It should be noted that the welding head transverse movement mechanism 32, the welding head lifting mechanism 33 and the welding head longitudinal displacement mechanism 34 all adopt at least one of a linear drive, a cylinder driving mechanism, a screw slider mechanism, a cam connecting rod mechanism, a gear rack mechanism, a chain sprocket mechanism, a synchronous belt synchronous wheel mechanism or a conveyor belt conveyor chain mechanism.

[0064] like Figures 1 to 6 As shown in the embodiment, the welding head transverse movement mechanism 32 adopts a motor-driven screw slider mechanism, all of the positioning parts are installed on the slider, and the motor drives the screw to rotate to drive the slider to move left and right, thereby causing all of the die heads 31 to move left and right.

[0065] like Figures 1 to 6 As shown in the embodiment, the positioning member lifting mechanism 43 adopts a cylinder pushing mechanism, the cylinder is fixedly arranged, the piston rod of the cylinder is fixedly connected to the welding head transverse movement mechanism 32, the piston rod of the cylinder is extended and retracted up and down, thereby driving the welding head transverse movement mechanism 32 to move up and down, so that all the die heads 31 are synchronously moved up and down.

[0066] like Figures 1 to 6 As shown in the embodiment, the welding head longitudinal displacement mechanism 34 adopts a cylinder driving mechanism, the cylinder body of the die head longitudinal displacement mechanism 34 is fixed on the slider of the die head transverse movement mechanism 32, and each cylinder piston rod of the die head longitudinal displacement mechanism 34 is respectively connected to a die head 31, and the cylinder piston rod of the die head longitudinal displacement mechanism 34 is extended and retracted to drive the corresponding die head 31 to move forward and backward.

[0067] Furthermore, the distance between two adjacent cutting dies 21 is adjustable.

[0068] More specifically, the distance between two adjacent cutting dies 21 is adjustable so that the cutting dies 21 can adapt to spring mattresses with different distances.

[0069] In order to further understand the specific advantages of the utility model, the utility model also proposes a bed net welding method without the need for the front and rear displacement of the knife die, and the bed net welding method is realized by the above-mentioned bed net welding equipment. A bed net production method proposed by the utility model includes the following steps:

[0070] S100: The first row of spring strings are transported to the welding area along the left and right directions. At this time, the first row of spring strings are laid on the die (such as Figure 7 shown);

[0071] S200: The feeding assembly conveys the next row of spring strings to the feeding area along the left and right directions, and then the welding head assembly moves up and down and left and right so that the welding head position corresponds to the position of the cutting die, and the welding head assembly moves forward and backward so that the welding head and the cutting die clamp the two rows of spring strings for welding (such as Figure 8 shown);

[0072] S300: The welding head assembly moves forward and backward to make the welding head away from the spring string, and then the welding head assembly moves up and down to avoid the feeding assembly, and then the knife die assembly moves up and down to make the knife die away from the spring string, and then the displacement assembly drives the welded spring string to move forward to the knife insertion area (such as Fig. 9 shown);

[0073] S400: The knife die is inserted between two rows of welded spring strings. At this time, the position of the knife die is offset from the welding position of the two rows of spring strings (such as Fig.10 shown);

[0074] S500: The displacement assembly drives the welded spring strings to move forward so that the rearmost row of spring strings reaches the welding area (such as Fig.11 shown);

[0075] Steps S200 to S500 are repeated until the spring strings are welded into a bed net of a predetermined size.

[0076] Furthermore, the step S100 specifically includes:

[0077] S101: The loading assembly conveys the first row of spring strings to the welding area, so that the first row of springs are laid on the cutting die of the cutting die assembly, and the loading assembly prepares to convey the second row of spring strings.

[0078] It should be noted that if Figures 1 to 6 In the implementation manner, step S101 specifically comprises that the dial 13 is displaced forward by a spring spacing so that the loading assembly 1 can directly deliver the spring string to the welding area 101, and then the loading group 1 is displaced left and right to input the first row of spring strings into the welding area 101, and then the dial 13 is displaced backward by a spring spacing to be reset. At this time, the position of the dial 13 corresponds to the feeding area 102, and at this time, the loading group 1 can feed the material to the loading area 102, thereby preparing for the input of the second row of spring strings.

[0079] It should be noted that, in other implementations, step S100 may also include:

[0080] S103: The feeding assembly conveys the first row of spring strings to the feeding area 102;

[0081] S104: Manually / machinely pushes the first row of spring strings to the welding area 101 .

[0082] It should be noted that, in other implementations, step S100 may also include:

[0083] S105: The feeding assembly conveys the first row of spring strings to the feeding area 102;

[0084] S106 : After the positioning member is extended, it moves in the front-to-back direction and pushes the spring string to the welding area 101 so that the spring string is laid on the cutting die 21 .

[0085] It should be noted that, in other implementations, step S100 may also include:

[0086] S107: The feeding assembly conveys the first row of spring strings to the feeding area 102;

[0087] S108: After the die head assembly is lifted, it moves in the front-to-back direction and pushes the spring string to the welding area 101 so that the spring string is laid on the cutting die 21 .

[0088] It should be noted that step 100 only needs to input the first row of spring strings into the feeding area 102, and its specific implementation method is not limited here.

[0089] For those skilled in the art, various other corresponding changes and modifications can be made according to the technical solutions and concepts described above, and all of these changes and modifications should fall within the protection scope of the claims of the utility model.
