In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0055] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] First, see Figures 1 to 3The present application provides a spring compression and pushing mechanism 100, which includes a compression mechanism 10, a conveying channel 20 and a first pushing mechanism 30. The compression mechanism 10 includes a clamping member 11, which is used to compress the spring 300 along the axial direction of the spring 300, and the compressed spring 300 is located at a compression position 112. The conveying channel 20 is connected to the compression position 112, and the outlet of the conveying channel 20 is connected to the cloth bag 401. The conveying channel 20 is used to keep the spring 300 in a compressed state during the conveying process of the spring 300. The conveying channel 20 is provided with a partition 21, which is used to be inserted into the spring 300 along the radial direction of the spring 300 to separate the spring steel wires, and the partition 21 extends from the compression position 112 to the outlet of the conveying channel 20. The first pushing mechanism 30 includes a first pushing member 31, which is movably arranged in the conveying channel 20 to push the spring 300 along the conveying channel 20 into the cloth bag 401. By utilizing the squeezing effect of the inner wall of the conveying channel 20 on the spring 300, the compressed spring 300 can be kept in a compressed state, and the spring 300 can be prevented from spreading before being bagged. By setting the conveying channel 20 to connect the compression position 112 and the cloth bag 401, and setting the compression position 112 to correspond to the position of the cloth bag opening 402, the spring 300 can be pushed by the first pushing member 31, and the compressed spring 300 can be directly pushed to the cloth bag 401. Since the compression mechanism 10 has achieved the compression of the spring 300, on the one hand, there is no need to use the conveying channel 20 to compress the spring 300, so that the length of the conveying channel 20 can be shortened, thereby shortening the transportation distance of the spring. On the other hand, by using the conveying channel 20 to connect the compression position 112 and the cloth bag 401, the distance from the compressed spring 300 to the cloth bag 401 can be shortened, which can not only improve the spring transportation efficiency, but also simplify the structural design of the spring compression and pushing mechanism 100 and reduce space occupancy. By providing the partition 21, the steel wires of the spring 300 can be separated from each other by the partition 21, so as to prevent the steel wires of the spring 300 from being entangled with each other after being compressed, thereby affecting the effect of the spring 300 being unfolded after being put into the bag. It is understandable that when the partition 21 is inserted into the spring 300, a certain space will be left along the radial direction of the spring 300 to avoid affecting the spring 300 passing through the conveying channel 20.

[0057] In some embodiments, the compression mechanism 10 includes a limit member 12 and two clamping members 11. The space between the two clamping members 11 forms a compression area 111. The limit member 12 is arranged at the periphery of the compression area 111. The two clamping members 11 can be close to each other to compress the spring 300. The limit member 12 is arranged at the periphery of the compression area 111 to limit the displacement of the spring 300 during the compression process of the spring 300. The limit member 12 is reserved with an opening for the spring 300 to enter the compression area 111. Fixing the spring 300 with two clamping members 11 can improve the balance of the stability of the spring 300 at both ends during the compression process. The limit member 12 can provide a limiting and fixing effect on the spring 300 in the radial direction of the spring 300 to prevent the spring 300 from deforming in the radial direction during the compression process. For example, as Figure 1 As shown, the limiting member 12 can be configured as a box-shaped structure with an opening, and the area inside the box-shaped structure forms a compression area 111 capable of accommodating the spring 300. The spring 300 can enter the compression area 111 through the opening, and the side wall of the box-shaped structure is used to limit the radial movement of the spring 300 to prevent the spring 300 from bouncing during the compression process. Optionally, the two clamping members 11 can be configured to be movable at the same time so that they can move closer to or farther away from each other. Of course, only one of the clamping members 11 can be moved, and the other can remain stationary, and the spring 300 can be compressed by moving one of the clamping members 11. Or in other examples, such as Fig.13 As shown, the limiting member 12 may be a baffle disposed on the outer peripheral side of the spring 300 to limit the radial movement of the spring 300 .

[0058] In some embodiments, the compression mechanism 10 further includes a first magnetic member (not shown), which is disposed on at least one clamping member 11 for adsorbing the spring 300. The first magnetic member may be a permanent magnet, such as a magnet, or an electromagnet. The first magnetic member can be used to adsorb and fix the spring 300 on the clamping member 11 to prevent the spring 300 from slipping during the compression process, thereby improving the stability of the spring 300 during the compression process. Exemplarily, the first magnetic member may be disposed on two clamping members 11, or may be disposed on only one of the clamping members 11. In some embodiments, please refer to Figures 4 to 6The spring compression and pushing mechanism 100 includes a compression spring assembly 15, and the compression spring assembly 15 includes a compression spring plate 151. The compression spring plate 151 is used to separate the spring 300 from the previous process and push the spring 300 to the compression area 111, or make the spring 300 fall into the compression area 111. Generally, after the spring 300 is manufactured, it is necessary to use a spring transfer device 202 to transport the spring 300 to the compression area 111. The spring transfer device 202 can fix the spring 300 using a fixing seat 2022 provided with a magnetic member to prevent the spring 300 from falling off during transportation. When the spring 300 is moved close to the compression area 111, the downward pressure of the compression spring plate 151 can overcome the magnetic adsorption force of the fixing seat 2022 on the spring 300, so that the spring 300 is separated from the fixing seat 2022 and falls into the compression area 111, or enters the compression area 111 through the driving action of the compression spring plate 151, thereby achieving the effect of the spring 300 automatically entering the compression area 111.

[0059] In some embodiments, the compression spring plate 151 is provided with a second magnetic member (not shown) for adsorbing the spring 300. When the compression spring plate 151 moves to the opening of the compression area 111, the spring 300 enters the compression area 111. The compression spring plate 151 can also be used to close a portion of the opening of the compression area 111. By using the second magnetic member to adsorb the spring 300, the stability of the spring 300 during transportation can be improved, and the spring 300 can be prevented from falling off or deforming. After the spring 300 enters the compression area 111, the compression spring plate 151 is used to close a portion of the opening of the compression area 111, which can further improve the effect of preventing the spring 300 from deforming during the compression process. In particular, for a spring 300 with a high compression ratio, the spring 300 is prone to radial deformation or displacement during the axial compression process. Therefore, the compression spring plate 151 is used to close a portion of the opening of the compression area 111 to improve the compression effect of the spring 300.

[0060] In some embodiments, the opening of the compression area 111 is located at the top of the compression area 111, and the compression spring plate 151 is vertically arranged above the opening. The compression spring plate 151 can vertically move the spring 300 to the compression area 111. By vertically arranging the compression spring plate 151 and the compression area 111, on the one hand, the spring 300 can be moved to the compression area 111 by the magnetic attraction of the compression spring plate 151, and can also directly fall into the compression area 111 after being separated from the fixing seat, thereby improving the accuracy of the process of the spring 300 entering the compression area 111. On the other hand, this can reduce the longitudinal (such as the longitudinal) movement of the compression spring plate 151. Figure 4In this way, the first pushing mechanism 30 can be arranged closer to the compression area 111, thereby shortening the pushing distance of the first pushing mechanism 30 and making the arrangement of the compression mechanism 10 more compact. Optionally, the compression spring plate 151 can be driven by a driving structure such as a motor or a cylinder, and the compression spring plate 151 moves up and down in the vertical direction under the driving action of the driving structure.

[0061] Understandably, Figures 4 to 6 The process of compressing and pushing the spring 300 by the spring compression and pushing mechanism 100 is shown. Figures 7 to 10 The process of the compression spring plate 151 separating the spring 300 from the fixing seat 2022 and driving the spring 300 to enter the compression area 111 is shown. After the spring 300 is compressed, it will be pushed along the conveying channel 20 to the cloth bag 401. For details, please refer to Figure 7 and Figure 8 , the conveying mechanism 2021 of the spring transfer device 202 rotates clockwise, driving the spring 300 close to the compression spring plate 151. When the spring 300 is transported to a position facing the compression spring plate 151, the compression spring plate 151 moves downward and absorbs and fixes the spring 300. The compression spring plate 151 continues to move downward, and the conveying mechanism 2021 continues to rotate clockwise, so that the spring 300 is separated from the fixing seat 2022. The compression spring plate 151 drives the spring to move vertically (such as Figure 8 The spring moves downward in the z-axis direction shown in the figure, so that the spring enters the compression area 111 between the two clamping members 11. Figures 4 to 6 as well as Fig. 9 , Fig.10 After the compression spring plate 151 drives the spring 300 to enter the compression area 111, the compression drive assembly 17 drives the two clamping members 11 to move in a lateral direction (such as Fig. 9 The first pushing mechanism 30 moves in the vertical direction (as shown in the x direction) to move closer to each other to compress the spring 300. The compressed spring 300 is located at the compressed position 112. Figures 4 to 6 , Fig.10 The spring 300 is pushed into the cloth bag 401 along the conveying channel 20 (as shown in the y direction) Fig.10 shown).

[0062] In some embodiments, see Figures 11 to 13 The stopper 12 can also be set as a baffle structure, which can be set on the outer peripheral side of the spring, and can also limit the radial movement of the spring 300. In this case, the stopper 12 can reserve a lateral opening for the spring 300 to enter. In this setting, in order to ensure that the spring 300 does not bounce during the compression process, please refer to Fig.15The compression mechanism 10 further includes a pressure plate assembly 14, which includes a pressure plate 141. The pressure plate 141 is movably arranged in the compression area 111. The pressure plate 141 is used to abut against the outer periphery of the spring 300 when the spring 300 enters the compression area 111. The pressure plate assembly 14 is also used to limit the displacement of the spring 300 during the compression process of the spring 300. The pressure plate 141 can be used to further limit the spring 300 during the compression process to avoid the problems of bouncing and deformation of the spring 300 during compression. When the spring 300 enters the compression area 111, the spring 300 will bounce because the spring 300 falls from a certain height. At this time, the spring 300 is pressed into the compression area 111 by the pressure plate 141, and the spring 300 can be quickly fixed, which saves the time of waiting for the spring 300 to stabilize and improves the compression efficiency of the spring 300. Since the stopper 12 needs to reserve a certain space to facilitate the spring 300 to enter the compression area 111, for example, the stopper 12 needs to reserve a certain distance from the spring 300 at least at the top or side, at this time, there is still room for the spring 300 to deform radially. Therefore, by setting the pressure plate 141, a certain extrusion force can be applied to the spring 300 at the top to achieve the function of limiting and fixing the spring 300. Fig.15 In the example shown, the vertically arranged baffle of the limiter 12 can limit the spring 300 in the horizontal direction, and at this time, the horizontally arranged pressure plate 141 can be used to limit the spring 300 in the vertical direction, so as to achieve a better fixing effect on the spring 300. At this time, a avoidance groove 311 can be set on the vertical baffle of the limiter 12 for the pressure plate 141 to pass through, and the pressure plate 141 moves downward under the driving action of a driving mechanism (such as a motor, a cylinder, etc.) to press against the outer periphery of the spring 300. When the spring 300 is compressed, the pressure plate 141 moves upward to leave the spring 300 and make way for the compression area 111 for the next spring 300 to enter.

[0063] In some embodiments, see Fig.14 and Fig.15The compression mechanism 10 further includes a compression spring assembly 15 and a guide ramp 16. The compression spring assembly 15 is arranged outside the compression area 111, and the guide ramp 16 is arranged below the compression spring assembly 15. The compression spring assembly 15 is used to separate the spring 300 from the spring transfer device 202, and the guide ramp 16 is used to guide the spring 300 to slide to the compression area 111. Before the spring 300 is compressed, the spring 300 made of steel wire is usually transported to the compression mechanism 10 by the spring transfer device 202. Exemplarily, the spring transfer device 202 uses a magnetic base to fix the spring 300 to ensure that the spring 300 does not fall during the transportation and transfer process. When the spring 300 is transported to the compression mechanism 10, the compression spring assembly 15 is used to move and poke the spring 300 under the driving action of the driving mechanism, so that the spring 300 slides off the fixed seat 2022. By utilizing the guiding function of the guide slope 16 , the spring 300 is guided to roll down along the surface of the guide slope 16 to the compression area 111 , thereby improving the convenience of transferring the spring 300 to the compression mechanism 10 .

[0064] In some embodiments, please refer to Figure 1 The compression mechanism 10 further includes a compression drive assembly 17, which includes two connecting arms 171 and a rotating disk 174. One end of the connecting arms 171 is respectively connected to the rotating disk 174, and the other end of the connecting arms 171 is respectively connected to the clamping members 11. The rotating disk 174 rotates to drive the two connecting arms 171 to move relative to each other, so as to drive the two clamping members 11 to move closer to or farther from each other. By utilizing the linkage between the rotating disk 174 and the connecting arms 171, the rotational motion of the rotating disk 174 can be converted into the linear motion of the connecting arms 171, thereby driving the clamping members 11 to move in a linear direction, so as to achieve the two clamping members 11 to move closer to or farther from each other.

[0065] Optionally, the compression drive assembly 17 may be provided with two turntables 174, and the disk surfaces of the two turntables 174 may be arranged in parallel, thereby saving the space occupied by the turntables 174. Furthermore, a driving structure (such as a motor) may be used to simultaneously drive the two turntables 174 to rotate, thereby ensuring the synchronization of the rotation of the two turntables 174. For example, the rotation speeds of the two turntables 174 are the same, the connecting arm 171 is provided with a slide groove 1711, and the connecting arm 171 is connected to the turntable 174 through a roller 1721 arranged on the turntable 174. The turntable 174 converts the rotational motion into the linear motion of the connecting arm 171 through the motion of the roller 1721 on the slide groove 1711, and the motion direction of the connecting arm 171 is perpendicular to the extension direction of the connecting arm 171. The turntable 174 can be driven by a motor, thereby converting a rotational motion into a linear motion of the two clamping members 11 that is synchronously relatively close to or away from each other.

[0066] In some embodiments, the compression drive assembly 17 further includes a guide rail mechanism 173, which extends along the moving direction of the connecting arm 171, and the connecting arm 171 is slidably connected to the guide rail mechanism 173. The use of the guide rail mechanism 173 can improve the stability and smoothness of the connecting arm 171 during the sliding process, and improve the reliability of the compression operation of the spring 300. The guide rail mechanism 173 can be connected to both ends of the connecting arm 171, and the same end of the two connecting arms 171 can be connected to the same guide rail mechanism 173 at the same time.

[0067] In some embodiments, along the axial direction of the spring 300, the rotating disk 174 is disposed on one side of one of the clamping members 11, and the disk surface of the rotating disk 174 is disposed vertically. In this way, the rotating disk 174 can be disposed vertically, reducing the space occupied by the rotating disk in the longitudinal direction of the compression area 111, so that the space outside the compression area 111 can be vacated and used to set the first pushing mechanism 30, thereby reducing the distance between the first pushing mechanism 30 and the compression position 112, shortening the pushing distance of the first pushing mechanism 30, and making the arrangement of the compression mechanism 10 more compact.

[0068] In addition to the above-mentioned rotating disk 174, the compression drive assembly 17 can also adopt the arrangement of the connecting arm 171 and the meshing gear 172. In some embodiments, see Figures 11 to 13 The compression mechanism 10 further includes a compression drive assembly 17, which includes two connecting arms 171 and two mutually meshing gears 172. The two connecting arms 171 are respectively slidably connected to the gears 172. The compression mechanism 10 includes two clamping members 11. The two connecting arms 171 are respectively connected to the clamping members 11. The rotation of the gears 172 drives the two connecting arms 171 to move relative to each other, so as to drive the two clamping members 11 to move closer to or farther from each other. The driving gear 172 is rotated to drive the two connecting arms 171 to move relative to each other to achieve the mutual approach or distance of the clamping members 11, which can ensure the synchronization and symmetry of the activities of the two clamping members 11 and improve the stability of the compression of the spring 300. Optionally, the two gears 172 rotate at the same speed, the connecting arm 171 is provided with a slide slot 1711, the connecting arm 171 is connected to the gear 172 via a roller 1721 provided on the gear 172, the gear 172 converts the rotational motion into the linear motion of the connecting arm 171 via the motion of the roller 1721 on the slide slot 1711, and the motion direction of the connecting arm 171 is perpendicular to the extension direction of the connecting arm 171. The gear 172 can be driven by a motor, thereby converting a rotational motion into a linear motion of the two clamping members 11 that is synchronously relatively close to or away from each other.

[0069] In some embodiments, the compression drive assembly 17 further includes a guide rail mechanism 173, which extends along the moving direction of the connecting arm 171, and the connecting arm 171 is slidably connected to the guide rail mechanism 173. The use of the guide rail mechanism 173 can improve the stability and smoothness of the connecting arm 171 during the sliding process, and improve the reliability of the compression operation of the spring 300. The guide rail mechanism 173 can be connected to both ends of the connecting arm 171, and the same end of the two connecting arms 171 can be connected to the same guide rail mechanism 173 at the same time.

[0070] In addition to being arranged along a longitudinal straight line, the conveying channel 20 can also be arranged in a form of being connected by multiple sections of channels. Figure 16 to Figure 17 In some embodiments, the conveying channel 20 includes a first channel 22 and a second channel 23 which are connected in sequence, the inlet of the first channel 22 is connected to the compression position 112, the outlet of the second channel 23 is connected to the cloth bag 401, and the first pushing member 31 is movably arranged in the second channel 23. The spring compression pushing mechanism 100 also includes a second pushing mechanism 40, the second pushing mechanism 40 includes a second pushing member 41, the second pushing member 41 is movably arranged in the first channel 22, the second pushing member 41 is used to push the spring 300 from the compression position 112 to the first channel 22, and the first pushing member 31 is used to push the spring 300 to the cloth bag 401 along the second channel 23. By setting up two channels, the goals of transporting the compressed spring 300 away from the compression position 112 and transferring the spring 300 to the cloth bag 401 can be achieved respectively. The two channels can respectively use the second pushing member 41 and the first pushing member 31 to complete the spring 300 pushing operation in sequence, avoid mutual interference between the two pushing members, and improve the efficiency and reliability of the spring 300 transportation process.

[0071] Exemplarily, the first pushing member 31 further includes a first driving mechanism 32 for driving the first pushing member 31 to move, and the second pushing member 41 further includes a second driving mechanism 42 for driving the second pushing member 41 to move. The first driving mechanism 32 and the second driving mechanism 42 may be motors, hydraulic cylinders or other power structures, and the first driving mechanism 32 and the second driving mechanism 42 may directly drive the first pushing member 31 and the second pushing member 41 to move, or may be driven by transmission structures such as connecting rod mechanisms and gears, which are not limited here.

[0072] Optionally, in one example, the first channel 22 and the second channel 23 may be arranged along a straight line, that is, the extension directions of the first channel 22 and the second channel 23 are substantially collinear, and when the spring 300 is compressed, the first pusher 31 pushes the spring 300 from the compressed position 112 into the first channel 22, and then the second pusher 41 is used to push the spring 300 into the cloth bag 401. Of course, in this example, only the first pusher 31 may be provided, and after the first pusher 31 pushes the compressed spring 300 from the compressed position 112 into the conveying channel 20, the spring 300 continues to be pushed until the spring 300 is pushed into the cloth bag 401.

[0073] In another example, the extension direction of the first channel 22 and the second channel 23 may not be collinear, and there is a certain angle between the two. That is, the extension direction of the first channel 22 intersects with the extension direction of the second channel 23. In this way, the compression step of the spring 300 and the step of transporting it to the cloth bag 401 can be separated from each other, and these two steps are completed in two different areas respectively. Compared with the collinear arrangement of the first channel 22 and the second channel 23, the arrangement of the first channel 22 and the second channel 23 in this example can make the two channels overlap to a certain extent in the extension direction of any channel, thereby shortening the length of the entire conveying channel 20 and improving the efficiency of transportation. At the same time, the shortened length of the conveying channel 20 can save space, making the structure of the spring compression and pushing mechanism 100 more compact.

[0074] The following description will be continued by taking the example that the extension direction of the first channel 22 intersects the extension direction of the second channel 23 .

[0075] In some embodiments, along the gravity direction, the compression position 112 is located above or below the entrance of the second channel 23. For example, the first channel 22 and the second channel 23 can be arranged perpendicular to each other (eg, Fig.16 As shown, for example, the first channel 22 is arranged in a vertical or substantially vertical direction, and the second channel 23 is arranged in a substantially horizontal direction, so that the compressed spring 300 can enter the second channel 23 along the first channel 22 under the vertical push of the second pushing member 41, and then enter the cloth bag 401 under the horizontal push of the second pushing member 41. The spring 300 compression mechanism 10 can be arranged above the first pushing mechanism 30, so that the two mechanisms are overlapped in the vertical direction, thereby saving the space occupied by the spring compression pushing mechanism 100 and making its structure more compact.

[0076] With this arrangement, the first channel 22 and the second channel 23 are arranged in a substantially L-shaped manner, so in some embodiments, the partition 21 extends from the entrance of the first channel 22 to the second channel 23, that is, the extension shape of the partition 21 is substantially the same as the shape of the conveying channel 20, thereby ensuring that the compressed spring 300 can be separated by the partition 21 during the entire conveying channel 20, thereby preventing the steel wire of the spring 300 from being entangled. Of course, in other examples, the partition 21 can also be arranged only in certain conveying sections of the conveying channel 20, which is not limited here.

[0077] It is understood that the cloth bag 401 is generally formed into a bag-like structure by folding the two sides of the cloth 400 with each other. Along the feeding direction of the cloth 400, the cloth 400 gradually closes, and the cloth bag opening 402 gradually decreases until the two sides of the cloth 400 completely overlap. The cloth bag opening 402 is set at the outlet of the conveying channel 20, so as to feed the spring 300 into the cloth bag 401 to form a bag spring string. The compression position 112 is set corresponding to the cloth bag opening 402, including the compression position 112 and the cloth bag opening 402 are located in approximately the same horizontal plane, and the first pushing member 31 pushes the spring 300 into the cloth bag 401 in the horizontal direction. In addition, the compression position 112 can also be set corresponding to the cloth bag opening 402 in the vertical direction, so that the projection of the compression position 112 in the vertical direction is located in the cloth bag opening 402, so that the pushing distance of the first pushing member 31 in the horizontal direction can be shortened, and the transportation efficiency of the spring 300 bagging can be improved. By arranging the compression position 112 close to the closing position of the cloth bag opening 402 , the pushing distance of the spring 300 can be further shortened, so that the spring 300 can be pushed into the cloth bag faster.

[0078] In some embodiments, see Fig.16 and Fig.17 , the first push member 31 and the second push member 41 are provided with an avoidance groove 311 for avoiding the partition 21. In this way, the first push member 31 and the second push member 41 can avoid interference with the partition 21 when sliding in the second channel 23 and the first channel 22 respectively. The first push member 31 and the second push member 41 can be a block structure, which can increase the contact area between the push member and the spring 300 and improve the stability of the pushing process. In order to ensure that the first push member 31 and the second push member 41 can pass smoothly in the conveying channel 20, the avoidance groove 311 is used for the partition 21 to pass through. Of course, in other examples, the depth of the partition 21 extending into the conveying channel 20 can be reduced and the volume of the push member can be reduced so that the push member and the partition 21 can be staggered when they meet. At this time, the avoidance groove 311 may not be provided on the push member. Optionally, the first push member 31 and the second push member 41 can both be provided with the avoidance groove 311, or only one of them can be provided with the avoidance groove 311, which is not limited here.

[0079] In some embodiments, the inner wall of the first channel 22 is provided with a first guide portion 221, and the outer periphery of the second pusher 41 is provided with a second guide portion 412. When the second pusher 41 moves along the first channel 22, the second guide portion 412 is connected with the first guide portion 221. On the one hand, the guide portion can be used to guide the movement of the second pusher 41 in the first channel 22, so as to avoid the second pusher 41 from deflecting during the pushing process of the first channel 22, thereby improving the matching accuracy of the two and improving the stability of the conveying process of the spring 300. On the other hand, the mutual cooperation of the two guide portions can also be used to make the second pusher 41 slide more smoothly in the first channel 22.

[0080] Similarly, in some embodiments, the second channel 23 and the first pushing member 31 can also adopt the same setting method, that is, the inner wall of the second channel 23 is provided with a third guide portion 231, and the outer surface of the first pushing member 31 is provided with a fourth guide portion 312. When the first pushing member 31 moves along the second channel 23, the fourth guide portion 312 and the third guide portion 231 are cooperated and connected with each other.

[0081] Exemplarily, one of the first guide portion 221 and the second guide portion 412 is a guide protrusion, and the other is a guide groove. Or one of the third guide portion 231 and the fourth guide portion 312 is a guide protrusion, and the other is a guide groove. The guiding function of the guide portion is achieved by the mutual engagement of the guide protrusion and the guide groove. Of course, in other examples, the guidance can also be achieved by providing a combination of a guide groove and a pulley, for example, a guide groove is provided on the inner wall of the conveying channel 20, and a pulley is provided on the outer wall of the first pushing member 31 or the second pushing member 41. When the first pushing member 31 or the second pushing member 41 slides in the conveying channel 20, the sliding action of the pulley is utilized to make the sliding of the pushing member smoother.

[0082] Second, see Fig.18 and Fig.19 The present application also provides a pocket spring machine 200, comprising the spring compression and pushing mechanism 100 provided in the first aspect, as well as a spring coiling device 201, a spring transfer device 202, a cloth support assembly 203 and a welding device 204. The spring coiling device 201 is used to coil the steel wire into a spring 300. The spring transfer device 202 is used to transfer the spring 300 from the spring coiling device 201 to the spring compression and pushing mechanism 100, and the spring transfer device 202 includes an annular conveying mechanism 2021 and a plurality of fixed seats 2022, wherein the plurality of fixed seats 2022 are arranged at intervals on the conveying mechanism 2021, and the fixed seats 2022 are provided with a third magnetic member, and the third magnetic member is used to adsorb the spring 300. The cloth support assembly 203 is used to convey the cloth and fold the cloth into a cloth bag 401. The welding device 204 is used to weld the cloth so that the spring 300 is encapsulated in the cloth bag 401.

[0083] In some embodiments, at least a portion of the conveying mechanism 2021 is bent inward to form an installation space, and the installation space is used to set at least one of the spring coiling device 201, the cloth support assembly 203, the first pushing mechanism 30, and the second pushing mechanism 40. In this way, on the one hand, the space vacated by the inwardly bent portion of the conveying mechanism 2021 can be fully utilized to set other mechanisms of the pocket spring machine 200, thereby reducing the volume of the pocket spring machine 200 and saving manufacturing space. On the other hand, by bending a portion of the conveying mechanism 2021 inward, the length of the conveying mechanism 2021 can be increased without increasing the volume of the conveying mechanism 2021, so as to accommodate more springs 300. Fig.18 , Fig.19 In the example shown, the conveying mechanism 2021 is provided with two inwardly curved parts, wherein the space provided by the upper curved arrangement is used to arrange the spring coiling device 201, and the space provided by the lower curved arrangement is used to arrange the first pushing mechanism 30 and a part of the compression mechanism 10, thereby making the structure of the pocket spring machine 200 more compact. Exemplarily, the conveying mechanism 2021 can be a conveyor belt, a conveyor chain, etc.

[0084] In some embodiments, see Fig.18 At least a portion of the conveying mechanism 2021 is located above the opening of the compression area 111, and the movement trajectory of the compression spring plate 151 intersects with the movement trajectory of the spring 300, so that when the fixed seat 2022 conveys the spring 300 to above the opening of the compression area 111, the compression spring plate 151 is used to separate the spring 300 from the fixed seat 2022 and transfer the spring 300 to the compression spring plate 151.

[0085] For example, Fig.18 For example, at least a portion of the conveying mechanism 2021 is protruded outward to form a conveying cantilever 2023, and the end of the conveying cantilever 2023 is vertically arranged above the opening of the compression area 111. Since the movement trajectories of the compression spring plate 151 and the spring 300 intersect, when the two move to intersect each other, the compression spring plate 151 can not only separate the spring 300 from the fixing seat 2022, but also adsorb and fix the spring 300 on the lower surface of the compression spring plate 151. In this way, the spring 300 can be transported to the opening position facing the compression area 111 under the movement of the compression spring plate 151, and the spring 300 is brought to the compression area 111 for compression. With this arrangement, the distance between the spring transfer device 202 and the spring compression and pushing mechanism 100 can be shortened, thereby shortening the path of the spring 300 from the spring transfer device 202 to the compression area 111, and improving the efficiency of the transportation and compression and pushing bagging of the spring 300.

[0086] In some embodiments, please refer to Figure 4 and Figure 5 The cloth support assembly 203 includes a screw rod 2033 and cloth support plates 2034 arranged on both sides of the conveying channel 20, the cloth bag 401 is wrapped around the outer side of the cloth support plates 2034, and the screw rod 2033 is respectively connected to the two cloth support plates 2034, and the screw rod 2033 is used to adjust the distance between the cloth support plates 2034 on both sides. By rotating the screw rod 2033 to adjust the distance between the cloth support plates 2034, the size of the cloth bag opening 402 is adjusted to meet the bagging requirements of springs 300 of different design specifications, so as to use the same set of bag spring machines 200 to manufacture bag spring products of different specifications.

[0087] See also Fig.19 The cloth support assembly 203 further includes a longitudinal welding member 2031, which is disposed at the outlet of the conveying channel 20 so that the cloth is sleeved on the outer periphery of the outlet of the conveying channel 20. In this way, when the first pushing member 31 pushes the spring 300 and the spring 300 leaves the second channel 23, it can directly enter the opened bag mouth, shortening the path of the spring 300 entering the cloth bag 401 and improving the bagging efficiency. Optionally, the cloth support assembly 203 further includes a plurality of cloth guide rollers 2032. After the cloth bag 401 is unrolled from the material roll, it is wound on the cloth guide rollers 2032, which helps to tighten the cloth bag 401 and follow the pushing rhythm of the spring 300 to achieve cloth feeding.

[0088] In some embodiments, see Figures 19 to 21 The pocket spring machine 200 further includes a spring feeding assembly 205, which is arranged downstream of the welding device 204 along the feeding direction of the spring string. The spring feeding assembly 205 includes two sets of thumbwheels 2051, which are respectively arranged on both sides of the spring string. The thumbwheels 2051 are provided with levers 2052 protruding from the outer periphery of the thumbwheels 2051. The levers 2052 on both sides of the spring string are used to clamp the welding part between two adjacent spring strings. The thumbwheels 2051 are used to rotate to drive the spring string to move. The thumbwheels 2051 can be used to squeeze the surface of the bagged spring string, and the levers 2052 protruding from the outer periphery of the thumbwheels 2051 can be inserted into the concave position between two adjacent spring strings, so that the thumbwheels 2051 rotate to drive the spring string to move.

[0089] In some embodiments, see Figure 1 and Fig. 22The pocket spring machine 200 also includes a cloth clamping assembly 206. The cloth clamping assembly 206 is disposed upstream of the welding device 204. The cloth clamping assembly 206 includes cloth clamping rods 2061 disposed in pairs. The two cloth clamping rods 2061 can be close to each other to clamp the cloth bag 401 before the spring 300 is packaged. Since the spring 300 is in a compressed state in the cloth bag, before the cloth bag 401 is welded, the two adjacent cloth bags 401 can be connected to each other, and the spring 300 can slide between the cloth bags. Therefore, the cloth clamping rods 2061 are disposed upstream of the welding device 204 to clamp the cloth bag 401, which can prevent the spring 300 from bending and deforming or getting entangled with each other in the cloth bag. Optionally, two groups of cloth clamping assemblies 206 can be provided. The two groups of cloth clamping assemblies 206 are arranged along the lateral direction of the cloth bag 401 (such as Fig.21 The two sets of cloth clamping components 206 are respectively arranged on both sides of the cloth bag 401, and the two sets of cloth clamping components 206 alternately clamp or release the cloth bag 401, and the cloth clamping components 206 clamp the cloth bag while moving along the longitudinal direction (y direction), thereby driving the spring string to move.

[0090] The following is the compression and pushing process of the pocket spring machine 200 on the spring 300:

[0091] Using a spring transfer device to transport the spring to above the opening of the compression area;

[0092] Using the compression spring plate to vertically separate the spring from the spring transfer device so that the spring enters the compression area;

[0093] The spring is compressed by the spring compression pushing mechanism. During the spring compression process, the compression spring plate is held against the outer periphery of the spring, and the compressed spring is located in the compressed position.

[0094] The first pushing member is used to push the spring into the cloth bag along the conveying channel.

[0095] By successively using the compression spring plate 151 and the first pushing member 31 to push the spring 300 along the space vertically above the compression area 111 and the conveying channel 20, the spring 300 can be separated from the fixing seat 2022 and enter the compression area 111. After the compression in the compression area 111 is completed, it is then pushed into the cloth bag 401 along the conveying channel 20 to complete the compression and bagging operation of the spring 300. By arranging the movement direction of the compression spring plate 151 vertically and connecting the compression position 112 with the cloth bag 401 through the conveying channel 20, the travel of the spring 300 to be pushed into the cloth bag is shortened, the transportation and pushing efficiency of the spring 300 is improved, and the structure of the spring compression and pushing mechanism 100 is made more compact.
