Description

TECHNICAL FIELD

[0001] The application relates to the technical field of spring pad core production, and particularly relates to a spring pad core combination device and a spring pad core. BACKGROUND

[0002] A spring pad core of a mattress or a sofa cushion is composed of a plurality of pocketed springs. In the production process, the continuous pocketed springs need to be cut into spring strings of a designed length, and then a plurality of rows of spring strings are bonded together by using an adhesive to form the spring pad core.

[0003] For the spring pad core of the mattress or the sofa cushion with an arc surface, pocketed springs of different heights need to be bonded and combined. The current spring pad core combination device adopts a mode of clamping the spring pad by using upper and lower conveying belts to bond and convey the spring pad. The mode is suitable for bonding and combining the spring pad with flat upper and lower surfaces, but cannot combine pocketed springs of different heights. In the bonding process, the side surface of the pocketed spring lacks limiting, so that the spring strings of the adjacent two rows of pocketed springs cannot be pressed tightly in the front and back directions during bonding, and the bonding of the spring strings is prone to being unstable.

[0082] The above drawings have shown the specific embodiments of the present application, which will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0083] The exemplary embodiments will be described in detail below with reference to the drawings. In the following description, like reference numerals refer to like elements throughout the description. The embodiments described in the following exemplary embodiments are not meant to represent all implementations consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims.

[0084] For the convenience of understanding, in the following, the conveying direction of the spring string on the working platform is set as the longitudinal direction, and the direction perpendicular to the longitudinal direction in the horizontal plane is set as the transverse direction.

[0085] With reference to Figure 1 and Figure 2 , the present embodiment provides a spring core combination device, comprising a rack 100, a working platform 200, a limiting mechanism 300, a glue spraying mechanism 400 and a feeding mechanism 500. The working platform 200 is arranged on the rack 100 and used for placing the spring string. Multiple rows of spring strings can be placed on the working platform 200 in sequence and combined into a spring core. The feeding mechanism 500 is arranged at the feeding end of the working platform and used for providing the spring string to the working platform 200. The glue spraying mechanism 400 is arranged between the working platform 200 and the feeding mechanism 500 and located at one side of the spring string, and used for spraying adhesive on the surface of the spring string to make the adjacent two rows of spring strings adhere to each other through the adhesive. The limiting mechanism 300 comprises a limiting piece 310 extending in the transverse direction and arranged above the working platform and movably connected with the rack 100 and capable of moving along the longitudinal direction on the surface of the working platform. The spring string in one row placed on the working platform 200 abuts against the limiting piece 310, and the limiting piece 310 moves adaptively along the longitudinal direction in the process of gradually increasing the number of combined spring strings, so as to make the adjacent two rows of spring strings adhere more firmly when the spring strings are adhered, and guide and position the spring string.

[0086] The working platform 200 is used for carrying the spring string. The working platform 200 only contacts the bottom of the spring string and has no limitation on the top of the spring string, so that the spring strings in a free state can be adhered to each other to form a spring string with a curvature by using bagged spring strings with different heights, and combined into a spring core with a flat bottom and an arc-shaped top, thereby improving the production effect of the spring core composed of bagged spring strings with different heights.

[0087] The limiter 310 can be a limiter plate perpendicular to the upper surface of the working platform 200 and is arranged above the working platform 200. When the spring gasket core is assembled, the first spring string placed on the working platform 200 rests against the surface of the limiter 310, and the spring string is positioned by using the limiter 310. When the working platform 200 drives the spring string to move at the discharge end, the limiter 310 also moves synchronously. When other spring strings are placed on the working platform 200 and squeezed and bonded with the spring string in front, the limiter 310 can limit the displacement of the spring string, thereby applying lateral force to the spring string, so that the two adjacent rows of spring strings are close together, thereby improving the tightness of each row of spring strings, and making the combined spring gasket core structure more solid and the size more accurate.

[0088] In some embodiments, the limit member 310 swings relative to the working platform 200 or moves in the vertical direction to change the distance between the limit member 310 and the working platform 200, so as to avoid the spring washer core so that the spring washer core can be output and unloaded.

[0089] For example, the limiting member 310 may be as follows Figure 3 As shown, the work platform 200 moves vertically. When the stopper 310 moves upward, the space between the stopper 310 and the work platform 200 increases, allowing the spring string to pass through and continue to be transported to the next link. When the stopper 310 moves downward, the space between the stopper 310 and the work platform 200 decreases, hindering the transportation of the spring string and forcing the spring string to abut against the stopper 310 to limit the spring string.

[0090] or as Figure 4 As shown in the swinging motion, when the stopper 310 swings to the horizontal position, the space between the stopper 310 and the working platform 200 increases, allowing the spring string to pass through. When the stopper 310 swings to the vertical position, the space between the stopper 310 and the working platform 200 decreases, hindering the conveyance of the spring string and forcing the spring string to abut against the stopper 310 to limit the spring string.

[0091] The distance between the limiter 310 and the working platform 200 is changed by vertical movement or swinging of the limiter 310. In the process of assembling the spring core, the limiter 310 is brought close to the working platform 200 to limit the spring string. When the spring core is assembled, the height of the limiter 310 can be increased to increase the distance between the limiter 310 and the working platform 200 so that the entire spring core formed after the spring string is assembled can pass through the bottom of the limiter 310 for subsequent processing operations. In addition, after one spring core is assembled, the limiter 310 can be restored to its initial position to continue to limit the next group of spring strings.

[0092] In some embodiments, the limiting member 310 can be connected with the rack through a rack and pinion mechanism to move in the vertical direction, or connected with the rack through a crank rocker mechanism to swing relative to the rack 100.

[0093] With reference to Figure 5 In some embodiments, the limiting member 310 includes an outer plate 311, an inner plate 312, a first magnet 313, and a driving member 314. The outer plate 311 is used to directly abut against the spring string and can be connected with the rack 100. The inner plate 312 is movably connected with the outer plate 311. The first magnet 313 is installed on the inner plate 312 and located on the side of the inner plate 312 close to the outer plate 311. The driving member 314 is installed on the outer plate 311 and connected with the inner plate 312, for driving the inner plate 312 and the first magnet 313 to approach or move away from the outer plate 311.

[0094] When the limiting member 310 limits the spring string on the working platform 200, the inner plate 312 can be driven by the driving member 314 to approach the outer plate 311, and the first magnet 313 on the inner plate 312 contacts the outer plate 311 to make the outer plate 311 have magnetism. When the spring string is pushed to the working platform 200, the spring string is limited by the outer plate 311 of the limiting member 310 with magnetism, thereby improving the accuracy of the position of the distance between each pocket spring during the bonding of the spring string and the stability of the adsorption. When the limiting member 310 is separated from the spring string, the inner plate 312 and the first magnet 313 are driven by the driving member 314 to move away from the outer plate 311, the outer plate 311 is demagnetized, and the spring string is separated from the outer plate 311 due to the loss of magnetic adsorption.

[0095] With reference to Figure 1 and Figure 6 In some embodiments, the limiting mechanism 300 further includes a first support 320 and a first support beam 330. The first support 320 is arranged on the rack 100. The first support beam 330 is movably arranged on the first support 320 and moves along the longitudinal direction relative to the first support 320. The limiting member 310 is arranged on the first support beam 330 and slides along the vertical direction relative to the first support beam 330.

[0096] The extending direction of the first support beam 330 can be parallel to the extending direction of the limiting member 310, and is arranged transversely above the working platform 200. The first support member 320 can be arranged in two, and is arranged at two ends of the first support beam 330 respectively. The two ends of the first support beam 330 are connected with the two first support members 320 respectively. The first support beam 330 and the first support member 320 can be connected through horizontal guide rails to enable the first support beam 330 and the limiting member 310 arranged on the first support beam 330 to slide relative to the rack 100 along the horizontal first direction. Similarly, the limiting member 310 can be connected with the first support beam 330 through vertical guide rails to enable the limiting member 310 to slide relative to the first support beam 330 along the vertical direction, thereby realizing the sliding of the limiting member 310 in the vertical direction.

[0097] In actual use, the first driving assembly 340 and the second driving assembly 350 can be arranged. The first driving assembly 340 is used to drive the first support beam 330 to slide, and the second driving assembly 350 is used to drive the limiting member 310 to slide.

[0098] For example, the first driving assembly 340 can include a first driving motor 341, a first driving shaft 342, a first gear 343, and a first rack 344. The first driving shaft 342 is arranged to rotate on the support beam. The first driving motor 341 is fixed relative to the first support beam 330 and is connected with the first driving shaft 342 through a speed reducer to drive the first driving shaft 342 to rotate. The first gear 343 is fixedly arranged on the first driving shaft 342. The extending direction of the first rack 344 is parallel to the first direction, and the first rack 344 is fixed on the first support member 320. The first rack 344 is engaged with the first gear 343. Thus, the first driving motor 341 can drive the first driving shaft 342 and the first gear 343 to rotate, and drive the first gear 343 to move on the first rack 344, thereby realizing the movement of the support beam in the first direction.

[0099] The second driving assembly 350 can include a second driving motor 351, a second driving shaft 352, a second gear 353, and a second rack 354. The second driving shaft 352 is arranged to rotate on the first support beam 330. The second gear 353 is fixedly arranged on the second driving shaft 352. The second driving motor 351 is fixed relative to the first support beam 330 and is connected with the second driving shaft 352 through a speed reducer to drive the second driving shaft 352 to rotate. The second rack 354 is arranged vertically on the limiting member 310 and is engaged with the first gear 343. The second driving motor 351 can drive the second driving shaft 352 and the second gear 353 to rotate, thereby driving the limiting member 310 to slide in the vertical direction.

[0100] Reference Figure 7In some embodiments, the work platform 200 is provided with a second magnet 210 for magnetically attracting a spring string placed on the work platform 200.

[0101] The second magnet 210 can be a permanent magnet or an electromagnet and is arranged on the inner side of the work platform 200. After the spring string is placed on the surface of the work platform 200, the second magnet 210 can keep the spring string stable in position, so that the spacing between the pocketed springs in the spring string remains unchanged during movement.

[0102] In some embodiments, the work platform 200 includes a conveyor belt for conveying the spring string in the longitudinal direction, and the second magnet 210 is arranged below the conveyor belt for attracting the spring string.

[0103] The work platform 200 can be one or more parallelly arranged belt conveyors. The work platform 200 has an upper end and a lower end. The spring string is placed vertically on the upper surface of the work platform 200 at the upper end. After a row of spring strings is placed on the surface of the work platform 200, the belt conveyor of the work platform 200 moves the spring string a corresponding distance in the direction of the lower end, thereby reserving space for the next row of spring strings. In this way, multiple rows of spring strings are placed on the surface of the work platform 200 to form a spring core.

[0104] Referring to Figure 1 and Figures 7-8 In some embodiments, the feeding mechanism 500 includes a second support 510, a first conveying member 520, and a pushing member 530. The second support 510 is arranged on the rack 100. The first conveying member 520 is arranged on the second support 510, and two first conveying members 520 are arranged opposite to each other to form a clamping channel.

[0105] The second support 510 can be arranged near the upper end of the work platform 200, and the conveying direction of the first conveying member 520 corresponds to the position of the work platform 200. During feeding, the pocketed springs of a corresponding length are placed in the clamping channel of the first conveying member 520 in sequence, and are moved to a designated position under the clamping and conveying action of the first conveying member 520. Then, the pushing member 530 is used to push the spring string formed by the pocketed springs out of the feeding chamber and onto the surface of the work platform 200, thereby achieving the purpose of automatically forming and feeding the spring string.

[0106] The pushing member 530 can be arranged inside the clamping channel of the first conveying member 520 and is slidably connected to the second support 510 through a guide rod. The pushing member 530 is slid in the direction of the work platform 200 to push the spring string in the feeding chamber out. The number of pushing members 530 can be two, and they are arranged at the clamping channel to act on the two ends of the pocketed springs, respectively, so that the pocketed springs are uniformly stressed during pushing and remain in a vertical posture.

[0107] The first conveying member 520 can include at least two conveying elements, and a clamping channel is formed between adjacent two conveying elements.

[0108] The sliding of the pushing member 530 can be controlled by setting a third driving assembly 540, which can be a gear and rack transmission structure, a lead screw and block transmission structure, or a hydraulic cylinder or air cylinder, etc. In the present embodiment, no specific limitation is made to this.

[0109] In some embodiments, the spring core combination device further includes a pushing member 530 movably arranged in the clamping channel, for pushing the spring string from the first conveying member 520 to the working platform 200. The pushing member 530 includes a third magnet 531, a demagnetization mechanism 532, and a pushing member body 533, and the pushing member body 533 is arranged in the clamping channel; the third magnet 531 is used for magnetically attracting the spring string during the pushing process, and the demagnetization mechanism 532 is connected with the pushing member body 533 and the third magnet 531, respectively, for driving the third magnet 531 to contact or separate from the pushing member body 533 after the spring string is pushed to the position, and then the pushing member body 533 is demagnetized and separated from the spring string.

[0110] The third magnet 531 can be a common magnet or an electromagnet. The pushing member body 533 can be a shell structure with a cavity, and the third magnet 531 is arranged on the inner side of the cavity of the pushing member body 533. When the pushing member 530 pushes the spring string out of the feeding chamber, the third magnet 531 can be used to adsorb the spring string to maintain the relative positions and distances of the bagged springs in the spring string, so that the spring string can be accurately positioned when moving to the working platform 200. After the spring string is adhered to the spring string on the front side of the working platform 200, the demagnetization mechanism 532 drives the third magnet 531 to move away from the pushing member body 533, the pushing member body 533 is demagnetized, and then the pushing member 530 retreats to the rear side of the feeding chamber, and the spring string will not be pulled back due to the magnetic force of the third magnet 531.

[0111] It should be noted that the distance between the two second supporting members 510 can be set according to the spring string with the smallest height in each row of spring strings, and the remaining spring strings can be deformed by elastic compression and then enter the feeding chamber. After the pushing member 530 pushes the combined spring string away from the feeding chamber, each bagged spring restores its initial length. The demagnetization mechanism 532 can be a cylinder driving mechanism.

[0112] In some embodiments, in order to be able to combine spring strings of different sizes, at least one of the two first conveying members 520 is slidably connected with the second supporting member 510, so as to be able to change the size of the clamping channel.

[0113] At least one conveying element in the first conveying member 520 is in sliding connection with the second support member 510, so as to change the distance between two adjacent conveying elements, and further change the size of the clamping channel.

[0114] For example, one of the conveying elements in the first conveying member 520 is fixed relative to the second support member 510, and the other conveying element is in sliding connection with the second support member 510 through a guide rail and can be controlled by the fourth driving assembly 550. The fourth driving assembly 550 can also be a gear and rack transmission structure, or a lead screw and block transmission structure, or a hydraulic cylinder or air cylinder, and the present embodiment does not make specific limitations.

[0115] Referring to Figure 7 and Figures 9-11 In some embodiments, the second support member 510 is rotationally arranged on the rack 100, so that the feeding mechanism 500 can be located at any position in the first station, the second station and the third station. When the feeding mechanism 500 is located at the first station, the first conveying member 520 is arranged in a horizontal direction, and the clamping channel formed by the first conveying member 520 can pass through manual feeding. When the feeding mechanism 500 is located at the second station, the first conveying member 520 is arranged in an inclined manner, for receiving the spring string cut to a set length, and the glue spraying mechanism 400 can pass through between the first conveying member 520 and the working platform 200, for spraying adhesive on the surface of the spring string. When the feeding mechanism 500 is located at the third station, the first conveying member 520 is arranged in a vertical direction, for conveying the spring string to the working platform 200.

[0116] As Figure 7 shown, the second support member 510 is rotationally connected with the rack 100 through a hinge shaft, and is provided with a fifth driving assembly 560 connected with the second support member 510, for driving the rotation of the second support member 510. The fifth driving assembly 560 can include a driving gear 561, a driven gear 562 and a pull rod 563. The driving gear 561 and the driven gear 562 are both rotationally connected on the rack 100, and the driving gear 561 and the driven gear 562 are hingedly connected with each other. One end of the pull rod 563 is hingedly connected at the outer edge of the driven gear 562, and the other end is hingedly connected with the second support member 510. The driving gear 561 is driven to rotate by a motor, and drives the rotation of the driven gear 562, and the second support member 510 can be driven to rotate through the pull rod 563.

[0117] In combination Figure 9When the feeding mechanism 500 is in the first station, the first conveying member 520 is arranged in a horizontal direction, the conveying elements of the first conveying member 520 are arranged in a relative horizontal direction, and the pushing member 530 is arranged horizontally. At this time, the operator can manually lay the spring string in the clamping channel. Thus, the manual placement can be realized to meet the situation that other materials such as sponge strips need to be added or single spring pad samples need to be made during the processing of the bad spring or spring pad core, so as to improve the flexibility of feeding and save the adjustment time of the machine.

[0118] In combination Figure 10 When the feeding mechanism 500 is in the second station, the first conveying member 520 and the pushing member 530 are in an inclined posture, so that the channel between the first conveying members 520 corresponds to the spring string feeding position, for receiving the spring string cut to a set length. The spring string in the working platform 200 is at a certain distance from the working platform 200, so that the glue spraying mechanism 400 can pass through the front side of the spring string to spray the adhesive.

[0119] In combination Figure 11 When the feeding mechanism 500 is in the third station, the first conveying member 520 is arranged in a vertical direction, and the conveying elements of the first conveying member 520 are arranged in a relative vertical direction, so that the spring string is in a vertical posture. The surface of the first conveying member 520 on the lower side is flush with the surface of the working platform 200, so that the spring string can be conveyed by the first conveying member 520 to the surface of the working platform 200.

[0120] With reference to Figure 1 And Figure 12 In some embodiments, the spring pad assembly device further comprises a feeding mechanism 600 corresponding to the position of the feeding mechanism 500 in the second station, for conveying the bagged springs to the feeding mechanism 500. The feeding mechanism 600 comprises a second conveying member 620, a clamping assembly 630 and a cutting assembly 640. The second conveying member 620 is used to convey the bagged springs to the feeding mechanism 500. The clamping assembly 630 is located at the discharge end of the second conveying member 620 and is connected with the input end of the first conveying member 520 of the feeding mechanism 500. The clamping assembly 630 has a clamping chamber 631 for accommodating the continuous bagged springs. The cutting assembly 640 is arranged between the second conveying member 620 and the clamping assembly 630, for cutting the continuous bagged springs into spring strings of a set length.

[0121] The second conveying member 620 can be provided as two, and the two second conveying members 620 are spaced apart in the vertical direction, so that the bagged springs can pass between the two second conveying members 620. When the feeding mechanism 500 is in the second station, the two first conveying members 520 correspond to the two second conveying members 620, so that the bagged springs can be moved from between the two second conveying members 620 to between the two first conveying members 520, realizing the feeding function of the bagged springs. The feeding mechanism 500 can further include a third support member 610, and the second conveying member 620 is installed on the third support member 610.

[0122] The clamping assembly 630 can be composed of a bottom plate and a plurality of partitions provided on the bottom plate, and a clamping chamber 631 is formed between each adjacent two partitions. The number of clamping chambers 631 is at least one, and the clamping assembly 630 can be slidably connected to the third support member 610 through two groups of mutually perpendicular guide rails. By sliding the clamping assembly 630, any clamping chamber 631 can be correspondingly communicated with the second conveying member 620 to convey the bagged springs placed in the corresponding clamping chamber 631 to the second conveying member 620.

[0123] By placing bagged springs of different lengths in different clamping chambers 631, and sequentially connecting the corresponding clamping chambers 631 with the second conveying member 620 during feeding, bagged springs of different lengths can be sequentially conveyed through the second conveying member 620 to the feeding chamber of the feeding mechanism 500 to be combined into spring strings with corresponding radii.

[0124] Among them, since the bagged springs are composed of a plurality of springs of the same size, after conveying the bagged springs of the corresponding length to the second conveying member 620, the cutting assembly 640 can be used to cut the connected bagged springs, so as to realize the purpose of obtaining bagged springs of corresponding length according to the size of the bagged springs.

[0125] The cutting assembly 640 can include a mounting bracket 641 and a cutter 642. The mounting bracket 641 is fixedly provided on the third support member 610, and the number of cutters 642 is two and symmetrically provided on the mounting bracket 641. Both cutters 642 are slidably connected to the mounting bracket 641 through a slide rod, and are driven by a cylinder or a hydraulic cylinder. In the initial state, a gap is reserved between the two cutters 642 for the bagged springs to pass through. When it is necessary to cut the bagged spring string, the two cutters 642 are controlled to move towards the direction of the bagged spring string at the same time, so as to cut the corresponding position of the bagged spring string.

[0126] Referring to Figure 16 and Figure 17As an optional embodiment, the feeding mechanism 500 further comprises a positioning assembly 570 arranged on the pushing member 530, for defining the position of the spring string in the transverse direction when the spring string is transferred from the feeding mechanism 500 to the working platform 200. The positioning assembly 570 comprises a positioning driving part 571 and two spring plate beaters 572. The two spring plate beaters 572 are respectively connected with the positioning driving part 571 and are driven by the positioning driving part 571 to move towards or away from each other, so as to define the position of the spring string in the transverse direction. The spring plate beaters 572 can rotate to avoid in the transverse direction, so that the bagged spring conveyed in the transverse direction can be smoothly conveyed into the feeding mechanism 500.

[0127] In some embodiments, the positioning driving part 571 comprises a driver 5711, a transmission member 5712, a finger air cylinder 5713 and a vertical plate 5714. The driver 5711 drives the transmission member 5712 to perform transmission movement. The finger air cylinder 5713 is fixed to the transmission member 5712 and is driven by the transmission member 5712 to move in the transverse direction. The finger air cylinder 5713 is connected with the spring plate beaters 572 to drive the spring plate beaters 572 to move to adjust the position. The spring plate beaters 572 are driven by the driving part 571 to move close to or away from each other, so as to facilitate adaptive positioning of the spring string. The finger air cylinder 5713 can also drive the spring plate beaters 572 to rotate to avoid in the transverse direction, so that the bagged spring conveyed in the transverse direction can be smoothly conveyed into the feeding mechanism 500. The vertical plate 5715 is located on the surface of the pushing member 530, for abutting against the limiting part in the longitudinal direction or pushing the spring string along with the pushing member 530.

[0128] In some embodiments, the transmission member 5712 can be a conveyor belt or a conveyor chain.

[0129] As an optional embodiment, the feeding mechanism 500 comprises at least two groups of positioning assemblies 570 distributed in the transverse direction, for simultaneously defining multiple rows of spring strings to be combined into multiple groups of cushion cores synchronously, or at least two groups of positioning assemblies 570 can be respectively used to enable only the outermost spring plate beaters to cooperate to combine the same group of cushion cores.

[0130] Referring to Figure 13 In some embodiments, the rack 100 is provided with a cloth roller 110 for conveying and guiding the base cloth and laying the base cloth on the working platform 200, so that the spring string placed on the working platform 200 is bonded with the base cloth.

[0131] The cloth roller 110 can be arranged on the lower side of the rack 100, and a plurality of layers of the base cloth are wound on the surface of the cloth roller 110. The base cloth is guided by a plurality of guide rollers and laid on the surface of the working platform 200 from the feeding end of the working platform 200. After the spring string is placed on the working platform 200, the bottom end of the spring string is bonded to the base cloth. The base cloth and the plurality of spring strings are combined to form a spring core, thereby further improving the overall stability of the spring core.

[0132] With reference to Figure 13 In some embodiments, the rack 100 is provided with a movable transverse cutter 120 for cutting the base cloth between two spring cores.

[0133] The transverse cutter 120 is arranged perpendicular to the conveying direction of the working platform 200 and is slidingly connected to the lower side of the working platform 200 and can also be driven by a cylinder or a hydraulic cylinder. The working platform 200 can be provided with a transverse cutting groove, and the transverse cutter 120 can be extended from the transverse cutting groove from bottom to top to cut the base cloth between the two spring cores.

[0134] With reference to Figures 13-15 In some embodiments, the spring core combination device further comprises a longitudinal cutter assembly 130, which comprises a fixed seat 131, a cutter body 132 and a driving mechanism 133. The fixed seat 131 is arranged at the output end of the working platform 200. The cutter body 132 is installed on the fixed seat 131. The driving mechanism 133 is connected with the cutter body 132 and drives the cutter body 132 to make reciprocating cutting action in the vertical direction, for cutting the spring core, so as to cut the combined plurality of connected spring cores into two or more symmetrical independent finished spring cores as shown in Figure 15

[0135] The cutter body 132 is arranged at the output end of the working platform 200 through the fixed seat 131, and the cutting edge of the cutter body 132 faces the side where the spring core advances, so that the spring core contacts the cutter body 132 during the advancing process. At the same time, the driving mechanism 133 drives the cutter body 132 to make longitudinal reciprocating cutting action, so as to cut the spring core.

[0136] ​In some embodiments, the fixed seat 131 includes a first fixed seat 1311 and a second fixed seat 1312. The first fixed seat 1311 is arranged at the upper end of the cutter body 132 and is rotationally connected with the rack 100. The second fixed seat 1312 is arranged at the lower end of the cutter body 132, and the second fixed seat 1312 is provided with a slidable guide block 1313 and an elastic member 1314 connected with the guide block 1313. The lower end of the cutter body 132 is movably connected with the second fixed seat 1312 through the guide block 1313, so that the cutter body 132 swings when it contacts the spring pad core and drives the elastic member 1314 to deform through the guide block 1313, thereby absorbing the impact force of the spring pad core on the cutter body 132.

[0137] The first fixed seat 1311 is located above the workbench 200, the second fixed seat 1312 is located below the workbench 200, and the tool seat 133 is vertically arranged between the first fixed seat 1311 and the second fixed seat 1312.

[0138] Referring to Figure 14 , a connecting member can be arranged on the rack 100, and the first fixed seat 1311 is rotationally arranged on the connecting member. When the spring pad core contacts the cutter body 132, the cutter body 132 is deflected and moved backward by the acting force, and drives the guide block 1313 on the second fixed seat 1312 to slide, so that the elastic member 1314 elastically deforms, thereby reducing the impact force of the spring pad core on the cutter body 132, and enabling the cutter body 132 to also produce a swing cutting action, thereby improving the cutting effect on the spring pad core.

[0139] The second fixed seat 1312 can be provided with a mounting groove, and a guide rod is arranged in the mounting groove. The guide block 1313 is slidably connected on the guide rod, and the elastic member 1314 can be a spring sleeved on the guide rod. The spring abuts between the guide block 1313 and the inner wall of the mounting groove. When the cutter body 132 drives the guide block 1313 to move, the spring is compressed and deformed, thereby absorbing the pulsating impact force generated when the spring pad core moves forward with pulsation during processing and conveying.

[0140] In some embodiments, the cutter body 132 is provided with a connecting rod 1321, and the guide block 1313 is provided with a connecting hole. The inner diameter of the connecting hole is greater than the diameter of the connecting rod 1321, and the connecting rod 1321 is inserted into the connecting hole. This enables the cutter body 132 to perform longitudinal reciprocating cutting action and swing cutting action relative to the guide block 1313, and enables the guide block 1313 to slide when the swing amplitude of the cutter body 132 is large.

[0141] In some embodiments, the longitudinal cutter assembly 130 further comprises a rotating member 134, a sliding member 135 and a crank 136. The rotating member 134 is rotatably connected to the first fixed seat 1311, the sliding member 135 is slidingly arranged in the first fixed seat 1311, and the crank 136 is hingedly connected to one end of the rotating member 134 and the other end of the sliding member 135. The rotating member 134 can drive the sliding member 135 to reciprocate by rotating. The cutter body 132 is connected to the sliding member 135.

[0142] The rotating member 134 can be driven by a driving motor, and when the rotating member 134 rotates, the sliding member 135 is driven to reciprocate by the crank 136, so as to realize the longitudinal reciprocating cutting action of the cutter body 132.

[0143] In some embodiments, the fixed seat 131 is slidingly arranged on the rack 100 to change the relative position of the longitudinal cutter assembly 130 and the working platform 200.

[0144] The upper and lower sides of the rack 100 can be provided with transverse guide rails, and the fixed seat 131 is slidingly arranged on the upper side to change the cutting position of the cutter body 132 on the spring core according to the combination form of the spring core.

[0145] Referring to Figure 1 and Figure 7 In some embodiments, the glue spraying mechanism 400 comprises a second support beam 410 and a spraying head 420. The second support beam 410 is fixedly arranged on the first support member 320, and the spraying head 420 is slidingly arranged on the second support beam 410, which is used to spray adhesive on the surface of the spring string to be placed on the working platform 200.

[0146] The second support beam 410 is arranged transversely above the working platform 200, the extension direction of the second support beam 410 is parallel to the extension direction of the first support beam 330, and the two ends of the second support beam 410 can be fixedly arranged on the two first support members 320, so that the entire glue spraying mechanism 400 can also rise or fall with the limiting mechanism 300. The spraying head 420 is slidingly connected to the second support beam 410 through a guide rail structure, so that the spraying head 420 can slide along the extension direction of the second support beam 410.

[0147] When the feeding mechanism 500 is in the second position, the spraying head 420 can slide relative to the second support beam 410 to pass in front of the feeding mechanism 500, and spray adhesive on the surface of the spring string in the feeding chamber. After the spraying is completed, the feeding mechanism 500 is moved to the third position to push the spring string with the surface coated with adhesive oil onto the working platform 200, and the spring string on the front side is adhered to each other.

[0148] The spring core combination device provided in the embodiments of the present application can realize the combination of pocket springs of different sizes into arc-shaped spring strings, the combination of the multiple rows of arc-shaped spring strings into a spring core with a flat bottom and an arc-shaped top, and the automatic cutting of the spring core, so as to realize the fully automatic combination production of the spring core with high efficiency. In addition, the spring strings are limited by the limiting member 310 during the combination process, so as to improve the tightness of the spring string combination and ensure the firm structure and accurate size of the spring core.

[0149] Based on the spring core combination device described above, the present application further provides a spring core made by the spring core combination device. The spring core includes multiple rows of spring strings, and the adjacent pocket springs in the same row and / or the adjacent two rows of pocket springs have a height difference, so that at least one side of the spring core is arc-shaped.

[0150] Reference Figure 18 The spring core 700 is composed of multiple rows of spring strings, and the adjacent two rows of spring strings are fixed by adhesives. The bottom of the spring core 700 is flat, and the top has a certain arc, so that the shape and structure design of the spring core 700 is easy.

[0151] The spring core 700 can be used to make products such as bed mattresses, sofa cushions, and seat cushions. The upper surface of the spring core 700 is arc-shaped in at least one direction. The use of multiple pocket springs with different heights to form the arc-shaped spring core 700 can facilitate the shape design of the cushion product and improve the aesthetic and comfortable degree of the cushion product.

The above description of the embodiments is only used to help understand the method of the present application and its core idea. Meanwhile, the changes or deformations made by the person skilled in the art based on the specific implementation modes and application scope of the present application all belong to the scope of protection of the present application. In summary, the content of the present specification should not be understood as a limitation of the present application.
