Description

Technical Field

[0001] This utility model relates to the technical field of bagged spring cushion production equipment, specifically to a spring cushion bonding device. Background Technology

[0002] Spring cushions are a common component in the production of furniture such as mattresses and sofas.

[0003] An adhesive device is required during the production of spring cushions.

[0004] Existing cushion bonding devices typically bond a bunch of bagged springs together and simultaneously bond nonwoven fabric above and / or below the bunch of bagged springs to form a cushion.

[0005] However, when bonding springs of different heights together to form a spring pad, the top surface fabric is bonded directly to the bottom and the end face of the highest pocket spring. In this case, the top surface fabric of the lower pocket spring is suspended in the air. This method makes the fabric prone to damage, affecting the quality of the finished product. Another method is to bond the fabric separately to the end faces of the higher and lower pocket springs. This method requires an additional bonding process and has lower production efficiency. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the present invention aims to provide a soft pad bonding device that can bond soft pads to the surface fabric composed of bag spring strings of different heights.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A spring cushion bonding device includes a feeding mechanism, a bonding mechanism, a fabric facing mechanism, and a fabric pressing mechanism.

[0009] The feeding mechanism is used to convey the spring string formed by arranging bagged springs along the first direction toward the bonding mechanism.

[0010] An adhesive mechanism for bonding two or more bundled bag springs together in a second direction to form a soft pad.

[0011] A fabric unwinding and tensioning mechanism is provided, which cooperates with the bonding mechanism to bond the fabric to at least one end face of the pad in a third direction.

[0012] A pressing mechanism, at least one pressing mechanism is located between the feeding mechanism and the bonding mechanism and can be independently displaced in a third direction, for limiting the face fabric to cooperate with the bonding mechanism and the face fabric mechanism to bond the stepped and / or inclined face fabric on the end face of the cushion.

[0013] Furthermore, the pressing mechanism is at least one pressing roller or pressing conveyor belt arranged along the second direction.

[0014] Furthermore, the feeding mechanism includes a feeding conveyor belt and a pushing mechanism. The feeding conveyor belt is used to input the bagged spring strings to a designated position, and the pushing mechanism pushes the bagged spring strings on the feeding conveyor belt toward the bonding mechanism.

[0015] Furthermore, the feed conveyor belt is a first clamping conveyor belt, and the clamping height of the first clamping conveyor belt is adjustable.

[0016] Furthermore, the bonding mechanism includes a glue spraying mechanism and a finished product conveyor belt. The glue spraying mechanism is located between the feeding mechanism and the finished product conveyor belt. The glue spraying mechanism is used to spray glue onto the bagged springs and / or the fabric. The finished product conveyor belt is used to receive and transport the soft pads of the bonded fabric or the bundle of bagged springs bonded together.

[0017] Furthermore, the finished product conveyor belt is a second clamping conveyor belt, and the clamping height of the second clamping conveyor belt is adjustable.

[0018] Furthermore, it also includes an output mechanism. At least one output mechanism is provided at the output end of the finished product conveyor belt for clamping and conveying the soft pad in conjunction with the finished product conveyor belt or the output mechanism. The output mechanism can be independently displaced in a third direction.

[0019] Furthermore, the pressing mechanism is located between the glue spraying mechanism and the finished product conveyor belt, and the face fabric enters the finished product conveyor belt through the pressing mechanism.

[0020] Furthermore, the fabric mechanism includes an unwinding device and a tensioning mechanism. The unwinding device is used to unwind and rewind the fabric, and the tensioning mechanism is used to keep the fabric in a tensioned state.

[0021] Furthermore, the tensioning mechanism includes a self-weight roller and a detection mechanism. The self-weight roller can be displaced at least in the vertical direction, and the fabric is wrapped around the self-weight roller. The detection mechanism is used to detect the position of the self-weight roller in the vertical direction.

[0022] Furthermore, the tensioning mechanism includes a self-weight roller and a detection mechanism. The self-weight roller can be displaced at least in the vertical direction, and the fabric is wrapped around the self-weight roller. The detection mechanism is used to detect the position of the self-weight roller in the vertical direction.

[0023] This utility model has the following beneficial effects:

[0024] This utility model discloses a spring cushion bonding device. By setting a pressing mechanism that can be displaced along a third direction to cooperate with the bonding mechanism, the device bonds stepped and / or inclined surface fabric to the end face of the cushion. This allows the bonding of the cushion surface fabric composed of bagged springs of different heights to be completed in one step, reducing the number of processes. Secondly, by bonding the stepped and / or inclined surface fabric through the pressing mechanism, the surface fabric is tightly bonded to the cushion, which is beneficial to the quality of the cushion.

[0035] 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.

[0036] like Figures 1-10 The present invention discloses a spring cushion bonding device, comprising a feeding mechanism 1, a bonding mechanism 2, a fabric covering mechanism 3, and a pressing mechanism 4.

[0037] Feeding mechanism 1 is used to convey the spring string formed by arranging bag springs along the first direction toward the bonding mechanism direction 2;

[0038] Adhesive mechanism 2 is used to bond two or more bag springs together in a second direction to form a soft pad.

[0039] The fabric mechanism 3 is used for unwinding and tensioning the fabric, and the fabric mechanism 3 cooperates with the adhesive mechanism 2 to adhesive the fabric to at least one end face of the cushion in a third direction.

[0040] The pressing mechanism 4 is located between the feeding mechanism 1 and the bonding mechanism 2 and can move independently along the third direction. It is used to limit the fabric to cooperate with the bonding mechanism and the fabric mechanism to bond the stepped and / or inclined fabric on the end face of the cushion.

[0041] It should be noted that, in the specific embodiment shown in the figure, the first direction is the front-back direction, the second direction is the left-right direction, and the third direction is the up-down direction.

[0042] It should be noted that a continuous fabric is bonded to the end faces of two bagged spring strings of different heights. When the fabric is also bonded to the side of the taller bagged spring string, the fabric is stepped. When the fabric is only bonded to the end faces of the two bagged spring strings, the fabric is inclined.

[0043] In use, the feeding mechanism 1 feeds the bagged springs arranged in the left-right direction to the designated position. Then, the feeding mechanism 1 feeds the bagged springs to the bonding mechanism 2 in the front-back direction so that the front and back bagged springs are bonded together. At the same time, the face cloth mechanism releases the face cloth so that the face cloth is also bonded to the upper end of the bagged springs at least synchronously. In this way, a soft pad with the face cloth bonded to the end is formed.

[0044] When it is necessary to bond the face fabric of bagged springs of different heights, such as Figures 2-5The diagram shows the bonding of a shorter bag spring string to a taller bag spring string. During this process, the pressing mechanism 4 moves downwards (in which case, the pressing mechanism 4 can cooperate with the bonding mechanism 2 to bond the fabric to the side of the taller bag spring string, thus creating a stepped shape when the fabric is bonded to the shorter bag spring string). Then, the feeding mechanism conveys the shorter bag spring string towards the bonding mechanism, allowing it to pass through the pressing roller 4. At this point, the fabric is bonded to the upper surface of the shorter bag spring string, thus completing the bonding of the fabric for bag spring strings of different heights. The fabric is now in a stepped shape on the pad. Figures 6-8 The diagram shows the bonding of a taller bag spring string to a shorter bag spring string. At this time, the pressing mechanism 4 moves upward, and then the feeding mechanism conveys the taller bag spring string towards the bonding mechanism so that the front of the taller bag spring string is in contact with the face fabric (at this time, the front of the bag spring string can be bonded to the face fabric) and passes through the pressing mechanism 4 so that the face fabric is bonded to the upper end face of the bag spring string. In this way, stepped or inclined face fabrics are bonded to the end faces of bag spring strings of different heights.

[0045] It should be noted that the pressing mechanism 4 can also be used to bond the fabric to the side of the spring string, thereby achieving the bonding of the stepped fabric.

[0046] The advantages of this utility model are: 1. By setting a pressing mechanism that can be displaced along a third direction to cooperate with the bonding mechanism to bond the stepped and / or inclined surface fabric on the end face of the soft pad, the bonding of the soft pad surface fabric composed of bag spring strings of different heights can be completed in one step, reducing the number of processes; 2. By bonding the stepped and / or inclined surface fabric through the pressing mechanism, the surface fabric is tightly bonded to the soft pad, which is beneficial to the quality of the soft pad.

[0047] Furthermore, the pressing mechanism 4 is at least one pressing roller or pressing conveyor belt arranged along the second direction.

[0048] It should be noted that the pressing mechanism 4 is preferably a pressing roller or a pressing conveyor belt; however, the pressing mechanism 4 only needs to be able to move in a third direction and limit the movement of the fabric.

[0049] Furthermore, the feeding mechanism 1 includes a feeding conveyor belt 11 and a pushing mechanism 12. The feeding conveyor belt 11 is used to input the bagged spring string to a designated position, and the pushing mechanism 12 pushes the bagged spring string on the feeding conveyor belt 11 toward the bonding mechanism 2.

[0050] It should be noted that the feed conveyor belt 11 conveys materials in the left-right direction, and the pusher mechanism 12 pushes materials in the front-back direction.

[0051] like Figure 1As shown, by setting up the feeding conveyor belt 11 and the pushing mechanism 12, the bag spring string can be conveyed from left to right, and then the bag spring string is pushed into the adhesive mechanism 2 in the front-back direction by the pushing mechanism 12, so as to cooperate with the subsequent adhesive action.

[0052] Furthermore, the feed conveyor belt 11 is a first clamping conveyor belt, and the clamping height of the first clamping conveyor belt is adjustable.

[0053] It should be noted that the feed conveyor belt 11 is a clamping conveyor belt with the upper and lower sides facing each other. By setting the upper and lower clamping conveyor belt, the accurate conveying position of the spring string is ensured, which is conducive to the accurate input of the spring into the adhesive mechanism 2 in the next step.

[0054] It should be noted that, as Figure 10 As shown, the pushing mechanism 12 includes an upper push plate 121 and a lower push plate 122. The upper push plate 121 and the lower push plate 122 correspond to the upper and lower conveyor belts of the feed conveyor belt 11, respectively. The upper push plate 121 and the lower push plate 122 can be relatively close to each other or far apart.

[0055] More specifically, by setting up an upper push plate 121 and a lower push plate 122, the upper push plate 121 and the lower push plate 122 can be relatively close or far apart according to the height of the bag spring string, thereby facilitating the accurate pushing of the bag spring string of different heights to the upper and lower positions.

[0056] It should be noted that the pushing mechanism 12 also includes a pushing drive 123, which is used to drive the upper pushing plate 121 and the lower pushing plate 122 to push synchronously.

[0057] Furthermore, the bonding mechanism 2 includes a glue spraying mechanism 21 and a finished product conveyor belt 22. The glue spraying mechanism 21 is located between the feeding mechanism 1 and the finished product conveyor belt 22. The glue spraying mechanism 21 is used to spray glue onto the bagged springs and / or fabric. The finished product conveyor belt 22 is used to receive and transport the soft pads of the bonded fabric or the bagged spring strings bonded together.

[0058] More specifically, the glue spraying mechanism 21 includes a glue spraying head 211 and a linear drive mechanism 212. The linear drive mechanism 212 drives the glue spraying head 211 to move along the spring arrangement direction of the bag spring string to spray glue onto the bag spring string and / or the fabric, while avoiding the bag spring string when the feeding mechanism 1 conveys it to the finished product conveyor belt 22.

[0059] More specifically, by setting up the finished product conveyor belt 22, it is convenient to transport the glued-together bagged spring strings and / or finished cushions, which is conducive to continuous production.

[0060] Furthermore, the finished product conveyor belt 22 is a second clamping conveyor belt, and the clamping height of the second clamping conveyor belt is adjustable.

[0061] More specifically, the finished product conveyor belt 22 adopts a second clamping conveyor belt, which has the advantages of stable and controllable conveying and the ability to stop and start as needed, making it convenient to convey the glued bagged spring strings to the designated position; at the same time, the clamping height of the second clamping conveyor belt is adjustable, so that the finished product conveyor belt 22 can clamp and convey according to the needs, which is convenient for conveying soft pads or glued bagged spring strings of different heights.

[0062] Furthermore, it also includes an output mechanism 5. At least one output mechanism 5 is provided at the output end of the finished product conveyor belt 22, which is used to clamp and convey the soft pad 101 in conjunction with the finished product conveyor belt 22 or the output mechanism 5. The output mechanism 5 can be independently displaced in a third direction.

[0063] More specifically, by setting the output mechanism 5, when the bag spring string of the higher part of the cushion is output from the output mechanism 5, the output mechanism 5 can be displaced in a third direction to clamp the bag spring string of the lower part of the cushion, thereby maintaining the clamping and conveying of the cushion.

[0064] Furthermore, the pressing mechanism 4 is located between the glue spraying mechanism 21 and the finished product conveyor belt 22, and the face fabric enters the finished product conveyor belt 22 through the pressing mechanism 4.

[0065] More specifically, the pressing mechanism 4 is located between the glue spraying mechanism 21 and the finished product conveyor belt 22, so that the glue spraying mechanism 21 can spray glue onto the fabric passing through the pressing mechanism 4, which is beneficial for the subsequent fabric bonding action.

[0066] Furthermore, the fabric mechanism 3 includes an unwinding device 31 and a tensioning mechanism 32. The unwinding device 31 is used to unwind and rewind the fabric, and the tensioning mechanism 32 is used to keep the fabric in a tensioned state.

[0067] More specifically, the unwinding device 31 is an unwinding roller connected to an external power source, which can rotate in both directions to achieve unwinding and rewinding of the fabric.

[0068] More specifically, by setting up the unwinding device 31, the unwinding and rewinding of the fabric can be controlled, which is beneficial for coordination with the subsequent fabric bonding action.

[0069] Furthermore, the tensioning mechanism 32 includes a self-weight roller 321 and a detection mechanism 322. The self-weight roller 321 can be displaced at least in the vertical direction, and the fabric is wrapped around the self-weight roller 322. The detection mechanism 322 is used to detect the position of the self-weight roller 321 in the vertical direction.

[0070] More specifically, by setting a self-weight roller 321 and a detection mechanism 322, the fabric can be kept in a taut state, which facilitates the adhesion of the fabric to the end face of the cushion.

[0071] Specifically, the detection mechanism 322 is used to detect the highest and lowest points of the self-weight roller 321. When the self-weight roller 321 reaches the highest point, the unwinding device 31 accelerates the unwinding of the fabric to avoid the fabric having too little allowance. When the self-weight roller 321 reaches the lowest point, the unwinding device 31 reduces the unwinding speed of the fabric to ensure that the fabric remains taut under the gravity of the self-weight roller 321. When the self-weight roller 321 is between the highest and lowest points, the unwinding device 31 maintains the unwinding speed.

[0072] 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.
