Description

Technical Field

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

[0002] A spring mattress is a commonly used piece of furniture, which is generally composed of a plurality of pocket spring strips.

[0003] Spring into the non-woven bag requires the use of spring into the bag welding equipment.

[0004] Existing spring bag welding equipment generally consists of a clamping and conveying mechanism, a non-woven bag, a clamping plate and a welding mechanism. The spring is input into the non-woven bag through the clamping and conveying mechanism, the clamping plate pulls the spring out of the non-woven bag, and then the welding mechanism seals the non-woven bag to form a bagged spring, and thus continuous production forms bagged spring strips.

[0005] However, the existing spring into bag welding equipment has the following problems: since the spring needs to be pulled out of the clamping and conveying mechanism through the clamping plate, the spring is in a free state in the non-woven bag after the clamping plate releases the spring, and in the process of the clamping plate pulling out the spring, the spring is forced to be close to the non-woven bag. When the spring is in a free state, it may form a rebound in the non-woven bag. At this time, the position of the spring is prone to misalignment, which is not conducive to the subsequent welding mechanism to seal the non-woven bag. Utility Model Content

[0006] The utility model aims to provide a spring-in-bag welding device to solve the deficiencies in the prior art.

[0007] To achieve this purpose, the utility model adopts the following technical solutions:

[0008] A spring bag welding device comprises a clamping and conveying mechanism, a non-woven bag, a welding mechanism and a cloth pulling mechanism;

[0009] The clamping and conveying mechanism is used to clamp and convey the springs one by one into the non-woven bag along a first direction;

[0010] The non-woven bag is arranged at the output end of the clamping and conveying mechanism, and the non-woven bag wraps the outer side of the clamping and conveying mechanism and extends outwardly along the first direction;

[0011] The welding mechanism can be relatively opened and closed along the second direction, and the welding mechanism can be displaced back and forth along the first direction to push the spring out of the clamping and conveying mechanism, and the welding mechanism is used to weld and seal the non-woven bag;

[0012] The cloth pulling mechanism is arranged at the output end of the clamping and conveying mechanism, and is used for pulling the non-woven bag along a first direction.

[0013] Furthermore, the welding mechanism includes a knife die and a welding knife, the knife die and the welding knife are arranged relative to each other along the second direction, the knife die and the welding knife can be synchronously / independently displaced back and forth along the first direction, and the knife die and the welding knife can be relatively close to or away from each other along the second direction.

[0014] Furthermore, the welding mechanism also includes a first driving mechanism, which is used to drive the knife die and the welding knife to move back and forth synchronously along a first direction.

[0015] Furthermore, the welding mechanism also includes a second driving mechanism, and the second driving mechanism is used to drive the knife die and the welding knife to move relatively close to each other or move away from each other in a second direction.

[0016] Furthermore, the second driving mechanism includes a clamping driving mechanism and a welding driving mechanism. The clamping driving mechanism is used to drive the knife die and the welding knife to open and close relative to fix or loosen the spring, and the welding driving mechanism is used to drive the knife die and the welding knife to clamp the non-woven bag to weld the non-woven bag.

[0017] Furthermore, the clamping conveying mechanism is composed of two groups of conveyor belts / conveyor chains arranged opposite to each other, each group of the conveyor belts / conveyor chains is composed of at least one conveyor belt / conveyor chain, and the distance between the two groups of the conveyor belts / conveyor chains is adjustable.

[0018] Furthermore, it also includes a cloth feeding mechanism, through which the non-woven fabric is output, and the non-woven fabric wraps the outside of the clamping and conveying mechanism to form a non-woven fabric bag.

[0019] Furthermore, the cloth pulling mechanism is two clamping plates arranged relatively along the second direction or the third direction, the two clamping plates can open and close relatively along the second direction or the third direction, and the two clamping plates can move back and forth along the first direction.

[0020] Furthermore, the cloth pulling mechanism is a transport mechanism disposed at the output end of the clamping and conveying mechanism, and the transport mechanism can transport along a first direction.

[0021] The beneficial effects of the utility model are as follows: by arranging a welding mechanism capable of pushing the spring and welding and sealing, the welding mechanism can directly push the spring out of the clamping and conveying mechanism and then directly weld and seal, thereby effectively avoiding the problem of rebound caused by the spring being in a free state in the non-woven bag; secondly, by arranging a cloth pulling mechanism, the non-woven bag is in a taut state, which is beneficial for the welding mechanism to fix the position of the spring through the non-woven bag.

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figure 1-Figure 6 As shown, a spring bag welding device includes a clamping and conveying mechanism 1, a non-woven bag 2, a welding mechanism 3 and a cloth pulling mechanism 4;

[0033] The clamping and conveying mechanism 1 is used to clamp and convey the springs one by one into the non-woven bag 2 along a first direction;

[0034] The non-woven bag 2 is arranged at the output end of the clamping and conveying mechanism 1, and the non-woven bag 2 wraps the outer side of the clamping and conveying mechanism 1 and extends outward along the first direction;

[0035] The welding mechanism 3 can be relatively opened and closed along the second direction, and the welding mechanism 3 can be displaced back and forth along the first direction to push the spring out from the clamping and conveying mechanism 1, and the welding mechanism 3 is used to weld and seal the non-woven bag 2;

[0036] The cloth pulling mechanism 4 is disposed at the output end of the clamping and conveying mechanism 1 and is used for pulling the non-woven bag 2 along a first direction.

[0037] It should be noted that the welding mechanism 3 is used to push the spring out of the clamping and conveying mechanism 1 to a specified position and then directly clamp the non-woven bag 2 for welding.

[0038] like Figures 1 to 6 As shown, the left-right direction is the first direction, the up-down direction is the second direction, and the front-back direction is the third direction.

[0039] like Figures 1 to 5 The figure shows one embodiment of the utility model. In this embodiment, the cloth pulling mechanism is a clamping plate that can be clamped up and down and can be displaced left and right, and the welding mechanism is

[0040] When the utility model is in specific operation, its workflow is as follows:

[0041] Step 1: The springs are fed into the non-woven bag 2 one by one through the clamping and conveying mechanism 1. At this time, the welding mechanism 3 and the cloth pulling mechanism 4 are in the initial position (such as Figure 1 shown);

[0042] Step 2: The welding mechanism 3 is relatively close to make the welding mechanism 3 contact with the non-woven bag 2, and the cloth pulling mechanism 4 clamps the non-woven bag 2. At this time, the welding mechanism 3 is in close contact with the non-woven bag 2, so that the non-woven bag 2 is deformed and clamps the spring, so that the welding mechanism 3 fixes the spring in the position of the non-woven bag 2 (such as Figure 2 shown);

[0043] Step 3: The welding mechanism 3 moves in the first direction (left-right direction), and the cloth pulling mechanism 4 drives the non-woven bag 2 to move synchronously. The displacement of the non-woven bag 2 drives the spring to move until the spring completely leaves the clamping conveying mechanism 1 and reaches a position suitable for welding (such as Figure 3 shown);

[0044] Step 4: The welding mechanism 3 is relatively close along the second direction (up and down direction) so that the welding mechanism 3 completely clamps the non-woven bag 2, and then the welding mechanism 3 performs sealing welding on the non-woven bag 2 (such as Figure 4 shown);

[0045] Step 5: After the sealing welding action is completed, the welding mechanism 3 moves away from the non-woven bag 2 in the second direction (upward and downward direction), and the cloth pulling mechanism 2 also moves away from the non-woven bag 2 (such as Figure 5 shown);

[0046] Step 6: The welding mechanism 3 and the cloth pulling mechanism 2 are synchronously displaced and reset along the first direction (eg Figure 1 shown);

[0047] Step 7: Repeat steps 1 to 6 until the welding and sealing process of one pocket spring strip is completed.

[0048] It should be noted that step 4 may also be replaced by:

[0049] Step 41: The welding mechanism 3 is relatively close in the second direction (upward and downward direction) so that the welding mechanism 3 completely clamps the non-woven bag 2, and then the welding mechanism 3 performs sealing welding on the non-woven bag 2. At the same time, the welding mechanism 3 and the cloth pulling mechanism 4 are synchronously displaced in the second direction (leftward and rightward direction) so that the spring reaches the specified position (such as Figure 4 shown).

[0050] More specifically, the advantages of the utility model are: 1. By providing a welding mechanism that can push the spring and weld and seal, the welding mechanism can directly push the spring out of the clamping and conveying mechanism and then directly weld and seal, effectively avoiding the problem of rebound caused by the spring in a free state in the non-woven bag; 2. By providing a cloth pulling mechanism, the non-woven bag is in a taut state, which is beneficial for the welding mechanism to fix the position of the spring through the non-woven bag.

[0051] Furthermore, the welding mechanism 3 includes a knife die 31 and a welding knife 32, the knife die 31 and the welding knife 32 are arranged relatively to each other along the second direction, the knife die 31 and the welding knife 32 can be synchronously / independently displaced back and forth along the first direction, and the knife die 31 and the welding knife 32 can be relatively close to or away from each other along the second direction.

[0052] More specifically, the welding knife 32 may be an ultrasonic welding knife, which has the advantages of fast welding speed and stable welding, and is conducive to rapid production.

[0053] Furthermore, the welding mechanism 3 further includes a first driving mechanism 33, and the first driving mechanism 33 is used to drive the knife die 31 and the welding knife 32 to move back and forth along the first direction synchronously.

[0054] More specifically, Figures 6 to 8 As shown in the embodiment, the first driving mechanism 33 uses a crank slider mechanism composed of a motor, a connecting rod, and a sliding seat. The crank slider mechanism has the advantages of stable, rapid, and fixed-distance reciprocating driving, which is beneficial to the reciprocating displacement of the welding mechanism 3 in the first direction.

[0055] It should be noted that the first driving mechanism 3 can also be driven by a cylinder drive, a screw slider drive, a sprocket chain drive, etc., as long as it can drive the cutting die 31 and the welding knife 32 to move back and forth in the first direction.

[0056] Furthermore, the welding mechanism 3 further includes a second driving mechanism 34, and the second driving mechanism 34 is used to drive the knife die 31 and the welding knife 32 to move relatively close to each other or move away from each other in a second direction.

[0057] One of the embodiments of the utility model: a driving mechanism (such as a screw slider, a crank slider, etc.) that can stop at any position is used to drive the knife die 31 and the welding knife 32 to move relatively close or away from each other, so that the knife die 31 and the welding knife 32 can hover at a specified position, thereby achieving the action of the knife die 31 and the welding knife 32 first getting relatively close to fix the spring, and then the knife die 31 and the welding knife 32 getting relatively close to clamp the non-woven bag 2.

[0058] Furthermore, the second driving mechanism 34 includes a clamping driving mechanism 35 and a welding driving mechanism 36. The clamping driving mechanism 35 is used to drive the cutting die 31 and the welding knife 32 to open and close relative to fix or loosen the spring, and the welding driving mechanism 36 is used to drive the cutting die 31 and the welding knife 32 to clamp the non-woven bag 2 to weld the non-woven bag 2.

[0059] like Figures 6 to 8 In the illustrated embodiment, the clamping drive mechanism 35 uses two sets of staggered crank slider mechanisms to drive the cutting die 31 and the welding knife 32 to be relatively close or away from each other, so that the cutting die 31 and the welding knife 32 can deform the non-woven bag 2 to fix the position of the spring when they reach the specified position. The welding drive mechanism 36 uses a cylinder, so that when the cutting die 31 and the welding knife 32 completely push the spring out of the clamping and conveying mechanism 1 to reach the specified welding position, the cylinder drives the cutting die 31 and the welding knife 32 to be relatively close to clamp the non-woven bag 2 for welding.

[0060] It should be noted that, in this embodiment, the second drive mechanism 34 uses two sets of drive mechanisms to realize the fixing action and welding action of the knife die 31 and the welding knife 32, thereby effectively avoiding the situation where a single drive causes the knife die 31 and the welding knife 32 to collide with the clamping and conveying mechanism 1 due to excessive driving.

[0061] Furthermore, the clamping conveying mechanism 1 is composed of two groups of conveyor belts / conveyor chains arranged opposite to each other, each group of the conveyor belts / conveyor chains is composed of at least one conveyor belt / conveyor chain, and the distance between the two groups of the conveyor belts / conveyor chains is adjustable.

[0062] More specifically, the distance between two adjacent conveyor belts / conveyor chains is adjustable, so that the clamping and conveying mechanism 1 can adapt to springs of different heights, which is conducive to the production of pocket spring strips of different specifications.

[0063] More specifically, the clamping conveying mechanism 1 also includes an adjusting mechanism 6, which includes a base 61, a screw 62 and a sliding seat 63. The base is fixedly arranged, the sliding seat 63 is slidably connected to the base, the screw 62 is threadedly connected to the sliding seat 63, and the two groups of conveyor belts / conveyor chains are respectively installed on the two sliding seats 63.

[0064] Rotating the screw rod 62 can adjust the distance between the two sliding seats 63, thereby adjusting the distance between the two groups of conveyor belts / conveyor chains.

[0065] Furthermore, it also includes a cloth feeding mechanism 5, through which the non-woven fabric is output, and the non-woven fabric wraps the outside of the clamping and conveying mechanism to form a non-woven fabric bag 2.

[0066] More specifically, by providing the cloth feeding mechanism 5 , the non-woven fabric can be kept tensioned to form the non-woven fabric bag 2 , which is beneficial for the subsequent cloth pulling mechanism 4 to pull and tension the non-woven fabric bag 2 .

[0067] Furthermore, the cloth pulling mechanism 4 is two clamping plates arranged relatively along the second direction or the third direction, the two clamping plates can open and close relatively along the second direction or the third direction, and the two clamping plates can move back and forth along the first direction.

[0068] like Figures 1 to 5 In the illustrated embodiment, the cloth pulling mechanism 4 is two clamping plates arranged opposite to each other along the second direction, and the non-woven bag 2 is clamped by the clamping plates, and then the clamping is displaced along the first direction to achieve the pulling mechanism 4 pulling the non-woven bag 2.

[0069] Furthermore, the cloth pulling mechanism 4 is a transport mechanism disposed at the output end of the clamping and conveying mechanism, and the transport mechanism can transport along a first direction.

[0070] like Figure 6 In the illustrated embodiment, the cloth pulling mechanism 4 is a conveying mechanism, and the finished pocket springs are clamped and conveyed by the conveying mechanism, thereby pulling the non-woven bag 2.

[0071] It should be noted that when the cloth pulling mechanism 4 is a conveying mechanism, the cloth pulling mechanism 4 maintains clamping the pocket spring, that is, the cloth pulling mechanism 4 maintains clamping the non-woven bag 2, and when the cloth pulling mechanism 4 is required to pull the bag, the conveying mechanism conveys along the first direction.

[0072] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
