Description

Technical Field

[0001] The present invention relates to the field of sponge processing, and particularly to a bagging system for sponge inner liners. Background Art

[0002] Polyurethane soft foamed rubber. Polyurethane is one of the most common polymer materials in life, widely used in making various sponge products, as well as elastic materials for shock absorption and anti-friction purposes, such as shoe soles and the lining of tractor and tank tracks.

[0003] When processing sponge products, first, a foaming resin, a foaming aid, and an adhesive resin (to make the finished product adhesive) are mixed together; then foaming processing is carried out. Mix ethylene vinyl acetate (EVA), APAOPT3385, azodicarbonamide, CaCO, and dicumyl peroxide together, place them in a mold for foaming, and use mechanical force to break the closed cells to obtain a foamed sponge product with a density (d) of 0.028 g / cm and a 25% compression hardness of 1.9 KPa.

[0004] Most of the components of the sponge are polyurethane. Just like foaming, the same material with different manufacturing processes will produce different things. PU sponge products mainly include polyester and polyether types that can be sliced or roll-cut, and can also be compounded, hot-pressed, and burst-opening processed according to customer requirements. Due to its characteristics such as heat preservation, heat insulation, sound absorption, shock absorption, flame retardancy, anti-static, and good air permeability, PU sponge products are involved in various industries, including the automotive industry, battery industry, cosmetics industry, brassiere and underwear manufacturing industry, and high-end furniture manufacturing industry, etc.

[0005] Currently, in the existing sponge production process, when storing, packaging, transporting, etc. the finished sponge, due to the limitations of the sponge's own material, inevitably the sponge itself will have a certain stickiness. Therefore, multiple sponges cannot be directly stacked for storage, otherwise, after a long time of contact, adjacent sponges are likely to stick together. In subsequent operations, the sponges need to be separated, which is rather troublesome and also likely to cause damage to the sponges. Therefore, in view of the above phenomenon, a gauze bag is put on the outside of the sponge as an inner liner of the sponge to avoid the occurrence of the above phenomenon. Currently, the traditional bagging method is all carried out manually, and the sizes of the existing gauze bags do not exactly match the sizes of the sponges. Instead, a yarn tube about dozens of meters long is cut, sewn, etc. to achieve a size that matches the size of the sponge. All of the above processes are carried out manually. During the entire bagging process, a large amount of manual labor is consumed, the manual labor intensity is high, and the work efficiency is not high. Therefore, in view of the above phenomenon, it is now hoped to develop an automatic bagging device to achieve automatic bagging of sponges. Summary of the Invention

[0043] The advantages of the present invention are as follows: In the bagging system of the present invention, through the mutual cooperation among the feeding unit, the bagging unit, the cutting and sewing unit, and the discharging unit, the automatic conveying and bagging of the sponge and the automatic cutting and sewing of the yarn bag are realized. The whole process greatly reduces manual labor, effectively saves labor force, and improves the corresponding working efficiency.

[0044] The feeding device, with the cooperation of the feeding support, the conveying roller, and the pushing unit, can provide a conveying driving force in another direction to the sponge after the sponge is conveyed in place, providing a basis for the subsequent smooth bagging of the sponge.

[0045] Regarding the setting of the pushing unit, by the mutual cooperation between the primary pushing component and the secondary pushing component, and using two times of pushing to realize the pushing and feeding of the sponge, it can push the sponge as far as possible while occupying a very small space, so as to facilitate the automatic bagging of the sponge and reduce the occupied area of the whole equipment.

[0046] The setting of the baffle plate is to limit the stroke of the sponge during the process of the sponge being conveyed along the first conveying direction, to prevent the sponge from exceeding the stroke and being unable to cooperate with the subsequent bagging process, and to facilitate the realization of the automation processing of the overall bagging.

[0047] Installing the pushing roller on the pushing plate is to avoid the pushing plate directly pushing the sponge when pushing the sponge, resulting in indentations of the pushing plate on the sponge.

[0048] Regarding the connection between the pushing cylinder and the feeding support, with the cooperation of two pushing cylinder mounting plates, and setting the connection point between the pushing cylinder and the pushing cylinder mounting plate above the conveying roller, so that when the pushing cylinder drives the pushing roller to move horizontally, it will not affect the work of the conveying roller.

[0049] The yarn drum feeding bracket, the upper sleeve assembly and the lower sleeve assembly cooperate with each other to open the yarn drum, so as to facilitate the continuous delivery of the sponge into the yarn drum, and provide a good foundation for the subsequent cutting and sewing of the yarn drum to realize the bagging of the sponge.

[0050] Two yarn bobbin loading brackets are provided, and the horizontal movement of the two yarn bobbin loading brackets is realized in cooperation with the first horizontal moving mechanism. This is because the length of the yarn bobbin is relatively long, that is, the bagging time is also relatively long. Therefore, two yarn bobbin loading brackets are used for switching, which saves the bagging time and improves work efficiency.

[0051] As for the first horizontal moving mechanism, the first horizontal moving guide rail, the first horizontal moving slider and the first linkage plate cooperate with each other, and only one motor is needed to realize the synchronous movement of the two bobbin feeding brackets, thereby simplifying the structure; and the setting of the moving roller is to make the movement of the bobbin feeding bracket more convenient.

[0052] For the setting of the second horizontal moving mechanism, the second guide groove, the second guide block, the second moving screw and the second screw nut are coordinated to realize the horizontal movement of the upper sleeve bracket to change the width of the entire upper sleeve assembly to meet the bagging of yarn tubes and sponges of different sizes, and it is more versatile; and the setting of the X-shaped second linkage plate is to enable each upper sleeve bracket to move horizontally, so that the distribution of each upper sleeve bracket is more even, and the bearing capacity for the installation of the yarn tube and the transportation of the sponge can be more uniform, avoiding the phenomenon of local excessive weight.

[0053] As for the setting of the third horizontal moving mechanism, the third guide groove, the third guide block, the third moving screw and the third screw nut are coordinated to realize the horizontal movement of the lower sleeve bracket, so as to change the width of the entire lower sleeve assembly to meet the bagging of yarn tubes and sponges of different sizes, and it is more versatile; and the setting of the X-shaped third linkage plate is to enable each lower sleeve bracket to move horizontally, so that each lower sleeve bracket can be distributed more evenly, and the bearing capacity for the installation of the yarn tube and the transportation of the sponge can be more uniform, avoiding the phenomenon of local excessive weight.

[0054] Through the cooperation of the first cutting and sewing component and the second cutting and sewing component, the two components are used to simultaneously cut and sew two positions of the yarn tube. This design realizes the cutting and sewing of the tail end of the previous yarn bag and the cutting and sewing of the front end of the next yarn bag, thereby realizing automatic cutting and sewing of the yarn bags without manual operation, thereby reducing manual labor.

[0055] For the yarn bobbin carding mechanism, the cooperation of the upper carding mechanism and the lower carding mechanism is adopted, so as to realize the simultaneous carding of the top side and the bottom side of the yarn bobbin, avoid the occurrence of large wrinkles on the yarn bag when the yarn bobbin is cut into a yarn bag after being filled with sponge, and affect the subsequent use.

[0056] For the setting of the third horizontal moving mechanism, through the cooperation of the third horizontal moving guide rail, the third horizontal moving plate and the third horizontal moving slider, only one motor can drive the movement, reducing the active driving parts and simplifying the structure.

[0057] For the setting of the fourth horizontal moving mechanism, through the cooperation of the fourth horizontal moving guide rail, the fourth horizontal moving plate and the fourth horizontal moving slider, only one motor can drive the movement, reducing the active driving parts and simplifying the structure.

[0058] For the setting of the third carding mechanism and the fourth carding mechanism, it is to press the yarn bag when using a overlock sewing machine to sew and seal the yarn bag, avoiding the opening of the yarn bag being too large due to cutting and affecting the smooth progress of sewing and sealing.

[0059] Through the cooperation among the collection component, the storage component and the transmission component, the waste yarn materials and thread ends generated during the cutting and overlock sewing processes of two groups of cutting machines and sewing machines can be recycled and stored simultaneously, avoiding the waste materials directly falling on the ground and affecting the surrounding environment, and being more conducive to realizing environmental protection in production.

[0060] For the baffle plate arranged on the transmission pipeline, it is to guide and convey the waste materials when the waste materials enter the transmission pipeline from the collection box, avoiding the waste materials being blocked at the feed port of the transmission pipeline and affecting the collection of the waste materials.

[0061] The material taking port and the box door arranged on the storage box are for opening the box door after the waste materials in the storage box reach a certain amount, facilitating the personnel to take out the waste materials. Brief Description of the Drawings

[0083] The following embodiments can enable those skilled in the art to understand the present invention more comprehensively, but do not limit the present invention within the scope of the described embodiments.

[0084] Such as Figures 1 - 20A sponge inner lining bagging system as shown includes a feeding unit, a bagging unit, a cutting and overlocking unit, and a discharging unit arranged in sequence.

[0085] As Figures 2 - 6 shown in the schematic diagram, the feeding unit includes

[0086] a feeding support 1, on which a number of conveying rollers 101 are installed. The two sides of the conveying rollers 101 are in rolling fit with the feeding support 1 through rotating shafts. Linkage sprockets 102 are installed on the rotating shafts on the same side of each conveying roller 101. Each linkage sprocket 102 is linked through a linkage chain to achieve linkage. Any one of the linkage sprockets 102 is driven by a rotating motor 103 installed on the feeding support 1 to rotate, so as to realize the synchronous and same-direction rotation of all the conveying rollers 101.

[0087] There is a discharging area on the feeding support 1. On the feeding support 1, an inlet side 104 and an outlet side 105 are respectively provided on the two adjacent sides of the discharging area, and the inlet side 104 and the outlet side 105 are distributed in a vertical direction. Correspondingly, there are two conveying directions of the sponge. The direction from the inlet side 104 to the discharging area is the first conveying direction of the sponge, and the direction from the discharging area to the outlet side 105 is the second conveying direction of the sponge. As Figure 5 shown, the conveying rollers 101 are arranged in parallel along the first conveying direction of the sponge, and the bagging unit, the cutting and overlocking unit, and the discharging unit are arranged in parallel in sequence along the second conveying direction of the sponge.

[0088] A baffle plate is also provided on the feeding support 1 on the side of the discharging area far from the inlet side 104. The height of the baffle plate is higher than the upper end point of the conveying roller 101. At the same time, a detection sensor for detecting the position of the sponge is equipped below the baffle plate on the feeding support 1. Through this detection sensor, it can cooperate with the rotating motor 103 in time after the sponge is conveyed beyond the stroke to stop the conveying of the sponge. The setting of the baffle plate is to limit the stroke of the sponge during the conveying process of the sponge along the first conveying direction, avoid the sponge not being able to cooperate with the subsequent bagging process after exceeding the stroke, and facilitate the realization of the automatic processing of the overall bagging.

[0089] A pushing unit is arranged on the feeding support 1. The pushing unit includes a primary pushing component and a secondary pushing component. For the setting of the pushing unit, the mutual cooperation between the primary pushing component and the secondary pushing component is adopted, and the sponge is pushed and fed by two times of pushing. It can push the sponge as far as possible on the basis of occupying a very small space, so as to facilitate the automatic bagging of the sponge and reduce the occupied area of the whole equipment.

[0090] The primary material pushing assembly includes a pushing plate 106 disposed on the side of the discharging area away from the discharging side 105. There are several pushing plates 106, which are arranged side by side along the first conveying direction at the side end of the loading support 1, and different pushing plates 106 are respectively located between two adjacent conveying rollers 101. Each pushing plate 106 is driven by a first pushing mechanism to reciprocate along the second conveying direction.

[0091] On the side of the pushing plate 106 close to the discharging area, a pushing roller 107 is also installed. The pushing roller 107 is vertically arranged, and the upper and lower sides of the pushing roller 107 are in rolling fit with the pushing plate 106. By installing the pushing roller 107 on the pushing plate 106, it is to avoid the pushing plate 106 directly pushing the sponge during the sponge pushing process, which may cause indentations of the pushing plate 106 on the sponge.

[0092] The first pushing mechanism is as follows: An auxiliary conveyor belt 108 is arranged below the discharging area on the loading support 1. The auxiliary conveyor belt 108 extends along the second conveying direction and is located at the middle position of the discharging area. The auxiliary conveyor belt 108 is driven to rotate by an auxiliary conveyor motor installed on the loading support 1. An auxiliary conveyor plate 109 is installed on the auxiliary conveyor belt 108. The auxiliary conveyor plate 109 extends along the first conveying direction, and the auxiliary conveyor plate 109 is fixedly connected to the upper layer of the auxiliary conveyor belt 108. The auxiliary conveyor plate 109 is driven by the auxiliary conveyor belt 108 to reciprocate along the second conveying direction. The bottom ends of the respective pushing plates 106 are installed on the upper end surface of the auxiliary conveyor plate 109 and are driven by the auxiliary conveyor plate 109 to synchronously reciprocate along the second conveying direction, thereby completing the sponge pushing action.

[0093] The secondary material pushing assembly includes a pushing roller 110 disposed above the discharging area. The pushing roller 110 faces the discharging side 105 of the loading support 1, and the extending direction of the pushing roller 110 is perpendicular to the extending direction of the conveying roller 101. The pushing roller 110 is driven by a second pushing mechanism to reciprocate along the second conveying direction.

[0094] The second pushing mechanism is as follows: A pushing cylinder 111 is connected to the middle position of the pushing roller 110, and the pushing cylinder 111 is hinged to the side of the loading support 1 away from the discharging side 105.

[0095] The connection between the pusher cylinder 111 and the loading support 1 is as follows: There is a pusher cylinder mounting bracket at the side end of the loading support 1. The pusher cylinder mounting bracket includes a pair of pusher cylinder mounting plates 112 extending above the conveying roller 101. A gap for mounting the pusher cylinder 111 is left between the two pusher cylinder mounting plates 112. The cylinder body of the pusher cylinder 111 is hinged to both of the two pusher cylinder mounting plates 112, and the hinge points between the cylinder body of the pusher cylinder 111 and the pusher cylinder mounting plates 112 are located above the upper end points of the conveying roller 101. For the connection between the pusher cylinder 111 and the loading support 1, the cooperation of the two pusher cylinder mounting plates 112 is adopted, and the connection points between the pusher cylinder 111 and the pusher cylinder mounting plates 112 are set above the conveying roller, so that when the pusher cylinder 111 drives the pusher roller 110 to move horizontally, it will not affect the operation of the conveying roller 101.

[0096] A swing support 113 is also provided beside the pusher cylinder 111 beside the loading support 1. There is a swing cavity 114 inside the swing support 113. The tail end of the pusher cylinder 111 extends into the swing cavity 114. A swing cylinder 115 is installed at the upper end of the swing support 113. The piston rod of the swing cylinder 115 extends into the swing cavity 114 and is located above the cylinder body of the pusher cylinder 111. A driving wheel 116 is also connected to the bottom end of the piston rod of the swing cylinder 115. The driving wheel 116 is in rolling cooperation with the piston rod of the swing cylinder 115. There is an annular groove on the middle position of the circumferential surface of the driving wheel 116 for the outer wall of the cylinder body of the pusher cylinder 111 to be embedded. The driving wheel 116 abuts against the outer wall of the pusher cylinder 111, and the driving wheel 116 is driven by the swing cylinder 115 to move up and down, thereby driving the pusher cylinder 111 to swing up and down. By using the cooperation among the swing support 113, the swing cylinder 115, and the driving wheel 116, the pusher cylinder 111 can be driven to swing up and down. In this way, when the pusher cylinder 111 is not in use, it can swing upward, so that the pusher cylinder 111 and the pusher roller 110 can avoid the sponge, as Figure 5 shown, to avoid the smooth conveyance of the sponge. Moreover, such a swinging method can realize the swinging of the pusher cylinder 111 without using a direct connecting piece to connect with the pusher cylinder 111, which is convenient for assembly, subsequent maintenance, etc.

[0097] As Figures 7 - 11 can be seen from the schematic diagram shown, the bagging unit includes

[0098] There are two yarn bobbin loading brackets 2 arranged side by side along the first conveying direction of the sponge beside the loading bracket 1, and the two yarn bobbin loading brackets 2 are driven by a first horizontal moving mechanism to reciprocate horizontally. The yarn bobbin loading bracket 2 is an L-shaped frame structure composed of a vertical bracket and a horizontal bracket, and both the vertical bracket and the horizontal bracket are rectangular frame structures. A triangular reinforcing bracket is also installed at the connection of the vertical bracket and the horizontal bracket. By setting two yarn bobbin loading brackets 2 and cooperating with the first horizontal moving mechanism to realize the horizontal movement of the two yarn bobbin loading brackets 2, it is because the length of the yarn bobbin is relatively long, that is, the time for bagging is relatively long. Therefore, two yarn bobbin loading brackets 2 are used for switching. When one yarn bobbin loading bracket 2 is docked to the entire automatic bagging system for work, the other yarn bobbin loading bracket 2 moves to the side. At this time, the yarn bobbin can be first sleeved on this yarn bobbin loading bracket 2 for standby. When the yarn bobbin on the first yarn bobbin loading bracket 2 is used up, it can be directly switched through the first horizontal moving mechanism, and the other yarn bobbin loading bracket 2 with the yarn bobbin already sleeved is directly docked to the automatic bagging system for continuous work. Repeating like this greatly saves the bagging time and improves work efficiency.

[0099] The first horizontal moving mechanism is as follows: A first horizontal moving base 201 is arranged below the two yarn bobbin loading brackets 2. A row of first horizontal moving guide rails 202 is installed on the upper end surface of the first horizontal moving base 201. The first horizontal moving guide rails 202 extend along the distribution direction of the two yarn bobbin loading brackets 2, that is, the first conveying direction of the sponge. First horizontal moving sliders that cooperate with the first horizontal moving guide rails 202 are also installed on the bottom surface of the yarn bobbin loading bracket 2. The two first horizontal moving sliders are connected by a first linkage plate 203 to achieve linkage. A first linkage motor 204 is installed on the first linkage plate 203. A horizontally arranged first moving roller is installed on the conveying shaft of the first linkage motor 204. At the same time, a first guide groove for the first moving roller to embed and roll is also provided at the side end of the first horizontal moving base 201, and the extending direction of the first guide groove is the same as the extending direction of the first horizontal moving guide rails 202. For the first horizontal moving mechanism, by the cooperation among the first horizontal moving guide rails 202, the first horizontal moving sliders, and the first linkage plate 203, only one motor can realize the synchronous movement of the two yarn bobbin loading brackets 2, which simplifies the structure, reduces the required active driving parts, and effectively reduces the cost.

[0100] A moving roller 205 is also provided below the yarn bobbin loading bracket 2. The moving roller 205 is provided to make the movement of the yarn bobbin loading bracket 2 more convenient. When the moving roller 205 is not installed, at least two first horizontal moving sliders need to be installed at the bottom end of the yarn bobbin loading bracket 2 to cooperate with the horizontal moving guide rail 202 to achieve movement. Moreover, at this time, the movement of the yarn bobbin loading bracket 2 is a horizontal sliding, and the friction between the yarn bobbin loading bracket 2 and the first horizontal moving base 201 is relatively large. In addition, the length of the first horizontal moving guide rail 202 needs to be equipped very long, and the entire occupied area is relatively large. After installing the moving roller 205, only one first horizontal moving slider needs to be installed on one yarn bobbin loading bracket 2. At this time, the first horizontal moving slider is equivalent to providing a moving direction, that is, power, for the roller of the moving roller 205, and the movement of the yarn bobbin loading bracket 2 mainly relies on the rolling of the moving roller 205, greatly reducing the friction between the yarn bobbin loading bracket 2 and the first horizontal moving base 201, making the movement of the yarn bobbin loading bracket 2 more convenient. Moreover, in this way, the first horizontal moving slider can be installed on the adjacent side of two yarn bobbin brackets 2, so as to shorten the length of the first horizontal moving guide rail 202 and greatly reduce the occupied area.

[0101] There is an opening on the yarn bobbin loading bracket 2 through which the sponge can pass. It is defined that one side of the yarn bobbin loading bracket 2 where the opening is located is the feeding side, and the other side of the yarn bobbin loading bracket 2 is the discharging side. An upper sleeve assembly and a lower sleeve assembly are installed at the discharging side of the yarn bobbin loading bracket 2 and are distributed up and down. The upper sleeve assembly and the lower sleeve assembly cooperate with each other to form a sleeve frame for sleeving the yarn bobbin, and a channel for sponge conveying is formed between the upper sleeve assembly and the lower sleeve assembly.

[0102] The upper sleeve assembly includes several upper sleeve brackets 206 distributed side by side in the horizontal direction on the upper side of the opening of the yarn bobbin loading bracket 2, and the distribution direction of the upper sleeve brackets 206 is perpendicular to the conveying direction of the sponge, and the upper sleeve brackets 206 extend along the conveying direction of the sponge.

[0103] Between each upper sleeve bracket 206, it is driven by a second horizontal moving mechanism to move reciprocally in the horizontal direction. The second horizontal moving mechanism is: there is a T-shaped second guiding groove 207 extending along the distribution direction of each upper sleeve bracket 206 at the side end of the yarn bobbin loading bracket 206. An upper auxiliary connecting plate 208 is fixed at the upper side end of the upper sleeve bracket 206. A T-shaped second guiding block embedded in the second guiding groove 207 is installed at the side end of the upper auxiliary connecting plate 208. The upper auxiliary connecting plate 208 fits the side end of the yarn bobbin loading bracket 2, and the side end of the upper sleeve bracket 206 extends into the upper side bottom surface of the yarn bobbin loading bracket 2 where the opening is located.

[0104] A second movable screw 209 is provided above the upper sleeve bracket 206 on the bobbin feeding bracket 2, and the second movable screw 209 extends along the distribution direction of each upper sleeve bracket 206, and the second movable screw 209 is driven to rotate by a second motor 210 installed on the bobbin feeding bracket 2, and a second screw nut 211 is provided on the second movable screw 209 for use therewith, and the second screw nut 211 is connected to an upper auxiliary connecting plate 208 located on one of the outermost upper sleeve brackets 2 through a transition connecting plate, and drives the upper sleeve bracket 2 to reciprocate along the extension direction of the second guide groove 207.

[0105] A second linkage plate is also connected between any two adjacent upper sleeve brackets 206. The second linkage plate is formed by hingedly connecting two second linkage rods 212 distributed in an X shape. The two sides of the second linkage plate are respectively hingedly connected to two adjacent upper sleeve brackets 2. For the setting of the second horizontal movement mechanism, the second guide groove 207, the second guide block, the second moving screw 209, and the second screw nut 211 are used to achieve the horizontal movement of the upper sleeve bracket 2, so as to change the width of the entire upper sleeve assembly to meet the bagging of yarn tubes and sponges of different sizes, and the versatility is stronger; and the setting of the X-shaped second linkage plate is to enable each upper sleeve bracket 2 to perform a certain ratio of horizontal movement, so that each upper sleeve bracket 2 is distributed more evenly, and the bearing capacity for the set of the yarn tube and the conveying of the sponge can be more uniform, avoiding the phenomenon of local overweight.

[0106] The lower sleeve assembly includes several lower sleeve brackets 213 which are horizontally arranged in parallel at the lower side of the opening of the yarn bobbin loading bracket 2, and the distribution direction of the lower sleeve brackets 213 is perpendicular to the conveying direction of the sponge. The lower sleeve brackets 213 extend along the conveying direction of the sponge, and the lower sleeve brackets 213 are provided with several lower sleeve conveying rollers 214 which are arranged in parallel along the conveying direction of the sponge.

[0107] Each lower sleeve bracket 213 is driven by a third horizontal moving mechanism to reciprocate along the horizontal direction. The third horizontal moving mechanism is: a T-shaped third guide groove 215 extending along the distribution direction of each lower sleeve bracket 213 is provided at the side end of the yarn bobbin loading bracket 2, and a lower auxiliary connecting plate 216 is also installed at the lower side end of the lower sleeve bracket 213, and a T-shaped third guide block embedded in the third guide groove 215 is installed at the side end of the lower auxiliary connecting plate 216.

[0108] On the yarn bobbin loading bracket 2, there is a third moving lead screw 217 below the lower sleeve bracket 213. The third moving lead screw 217 extends along the distribution direction of each lower sleeve bracket 213, and the third moving lead screw 217 is driven by a third motor 218 to rotate. There is a third lead screw nut cooperating with the third moving lead screw 217, and the third lead screw nut is connected to the lower auxiliary connecting plate 216 on one of the outermost lower sleeve brackets 213 through a lower transition connecting plate 219, and drives the lower sleeve bracket 213 to reciprocate along the third guiding groove 215. Moreover, the lower sleeve bracket 213 connected by the third lead screw nut and the upper sleeve bracket 206 connected by the second lead screw nut 211 are the lower sleeve bracket 213 and the upper sleeve bracket 206 on the same side.

[0109] A third linkage plate is also connected between any two adjacent lower sleeve brackets 213. The third linkage plate is formed by hinging two third linkage rods 220 distributed in an X shape, and both sides of the third linkage plate are hinged between two adjacent lower sleeve brackets 213. For the setting of the third horizontal moving mechanism, the cooperation between the third guiding groove 215, the third guiding block, the third moving lead screw 217, and the third lead screw nut is adopted, so as to realize the horizontal movement of the lower sleeve bracket 213, change the width of the entire lower sleeve assembly, and meet the bagging of yarn bobbins and sponges of different sizes, with stronger versatility; the setting of the X-shaped third linkage plate is to enable each lower sleeve bracket 213 to be able to move horizontally, so that the distribution of each lower sleeve bracket 213 can be more uniform, and the bearing force for the bagging of the yarn bobbins and the conveying of the sponges can be more uniform, avoiding the phenomenon of excessive local weight.

[0110] As Figures 12 - 16 shown in the schematic diagram, the cutting and overcasting unit includes

[0111] a first cutting and overcasting assembly and a second cutting and overcasting assembly that are arranged side by side in sequence along the second conveying direction of the sponge beside the yarn bobbin loading bracket 2.

[0112] The first cutting and overcasting assembly includes a first cutting and overcasting bracket 3. A yarn bobbin combing mechanism is installed on the side of the first cutting and overcasting bracket 3 away from the second cutting and overcasting assembly. The yarn bobbin combing mechanism includes an upper combing mechanism and a lower combing mechanism, and a gap for the yarn bobbin and the sponge to pass through is left between the upper combing mechanism and the lower combing mechanism. For the yarn bobbin combing mechanism, the cooperation between the upper combing mechanism and the lower combing mechanism is adopted, so as to realize the simultaneous combing of the top side and the bottom side of the yarn bobbin, and avoid the phenomenon that the yarn bag has large wrinkles when the yarn bobbin is cut into a yarn bag after the sponge is loaded, which affects the subsequent use.

[0113] The upper carding mechanism includes an upper carding bracket 301 installed at the upper side end of the first cutting and overcasting bracket 3. The upper carding bracket 301 is hinged to the first cutting and overcasting bracket 3, and the upper carding bracket 301 is driven by an upper swing motor installed on the first cutting and overcasting bracket 3 to swing up and down along the hinge point between the upper carding bracket 301 and the first cutting and overcasting bracket 3. On the side of the upper carding bracket 301 away from the first cutting and overcasting bracket 3, an upper carding roller 302 is installed, and the upper carding roller 302 is connected to the upper carding bracket 301 through a bearing and a bearing housing for rolling connection. The upper carding roller 302 is driven to rotate by an upper carding motor 303 installed on the upper carding bracket 301.

[0114] The lower carding mechanism includes a lower carding platform 304. Above the lower carding platform 304, a lower carding roller 305 is provided. Both sides of the lower carding roller 305 are movably installed on a lower carding seat 306, and the lower carding roller 305 is connected to the lower carding seat 306 through a bearing and a bearing housing for rolling connection. The two lower carding seats 306 are respectively driven by independent lower driving cylinders 307 to move up and down, thereby driving the lower carding roller 305 to move up and down. In this embodiment, the lower driving cylinder 307 is a hydraulic cylinder. The lower carding roller 305 is driven to rotate by a lower carding motor 308 installed on one of the lower carding seats 306. On the lower carding platform 304, lower guide plates 309 are also provided beside the lower driving cylinders 307. A lower guide rod 310 is also connected to the bottom surface of the lower carding seat 306. At the same time, the lower guide plate 309 has a guide hole for the lower guide rod 310 to pass through and move.

[0115] On the side of the first cutting and overcasting bracket 3 close to the second cutting and overcasting assembly, a first overcaster 311 and a first cutting machine 312 are installed. The first overcaster 311 and the first cutting machine 312 are driven by a third horizontal moving mechanism to move horizontally along the side end of the first cutting and overcasting bracket 3, and the horizontal moving direction is perpendicular to the conveying direction of the sponge. The first cutting machine 312 is located at the front side of the moving track. By placing the first cutting machine 312 at the front side, that is, first cutting the yarn bobbin, and then overcasting the cut, it can avoid cutting the overcasting thread during subsequent cutting when overcasting first, which affects the sealing effect.

[0116] The third horizontal moving mechanism is as follows: on the side of the first cutting and overedging bracket 3 close to the second cutting and overedging bracket, there are two columns of third horizontal moving guide rails installed. They are distributed from top to bottom in sequence at the side end of the first cutting and overedging bracket 3. The extending direction of the third horizontal moving guide rails is perpendicular to the conveying direction of the sponge. The first overedging machine 311 and the first cutting machine 312 are installed on the third horizontal moving plate 314. On the third horizontal moving plate 314, there are third horizontal moving sliders installed which are used in cooperation with the third horizontal moving guide rails. The third horizontal moving plate is horizontally moved by the cooperation of a third horizontal lead screw and a third lead screw nut. The extending direction of the third horizontal lead screw is the same as that of the third horizontal moving guide rails. The third horizontal lead screw is installed at the side end of the first cutting and overedging bracket 3 and is located between the two third horizontal moving guide rails. There is a third lead screw nut used in cooperation with it on the third horizontal lead screw. This third lead screw nut is fixed on the third horizontal moving plate 314. The third horizontal lead screw is driven to rotate by a third horizontal moving motor installed on the first cutting and overedging bracket 3, so as to drive the third horizontal moving plate 314 to move horizontally, and then drive the first overedging machine 311 and the first cutting machine 312 to move horizontally. For the setting of the third horizontal moving mechanism, through the cooperation of the third horizontal moving guide rails, the third horizontal moving plate 314 and the third horizontal moving sliders, only one motor can drive the movement, reducing the active driving parts and simplifying the structure.

[0117] On the side end of the first overedging machine 311, there is also a third carding mechanism installed. The third carding mechanism includes several third carding rollers 315 arranged on the side of the first overedging machine 311 close to the first cutting and overedging bracket 3. Each of the third carding rollers 315 is linked through a third linkage belt 316. And the third linkage belt 316 has a horizontal section flush with the upper end surface of the third horizontal moving plate 314. A gap for the end of the yarn bag to pass through is jointly formed between the horizontal section of the third linkage belt 316 and the upper end surface of the third horizontal moving plate 314. Any one of the third carding rollers 315 is driven to rotate by a third carding motor installed on the first overedging machine 311 and drives the third linkage belt 316 to rotate. On the side of the first overedging machine 311 close to the first cutting machine 312, there is also a third carding pressing plate 317 installed. A gap for the end of the yarn bag to pass through is jointly formed between the third carding pressing plate 317 and the upper end surface of the third horizontal moving plate 314.

[0118] The second cutting and overlocking assembly includes a second cutting and overlocking bracket 318. On the side of the second cutting and overlocking bracket 318 close to the first cutting and overlocking assembly, a second overlock sewing machine 319 and a second cutting machine are installed. The second overlock sewing machine 319 and the second cutting machine are driven by a fourth horizontal moving mechanism to move horizontally along the side end of the second cutting and overlocking bracket, and the horizontal moving direction is perpendicular to the conveying direction of the sponge. The second cutting machine is located at the front side of the moving track. By placing the second cutting machine at the front side, that is, first cutting the yarn tube and then overlocking the cut, it can avoid cutting the overlock thread during subsequent cutting when overlocking first, which affects the sealing effect.

[0119] The moving direction of the second overlock sewing machine 319 and the second cutting machine is opposite to the moving direction of the first overlock sewing machine 311 and the first cutting machine 312. Such a setting is to avoid mutual influence among the second overlock sewing machine 319, the second cutting machine, the first overlock sewing machine 311, and the first cutting machine 312 when they move in the same direction.

[0120] The fourth horizontal moving mechanism is as follows: On the side of the second cutting and overlocking bracket 319 close to the first cutting and overlocking bracket 3, two columns of fourth horizontal moving guide rails 320 are installed, which are distributed vertically from top to bottom at the side end of the second cutting and overlocking bracket 319. The extending direction of the fourth horizontal moving guide rails 320 is perpendicular to the conveying direction of the sponge. The second overlock sewing machine 319 and the second cutting machine are installed on a fourth horizontal moving plate 321. Fourth horizontal moving sliders that cooperate with the fourth horizontal moving guide rails 320 are installed on the fourth horizontal moving plate 321. The fourth horizontal moving plate 321 is horizontally moved by the cooperation of a fourth horizontal lead screw 322 and a fourth lead screw nut. The fourth horizontal lead screw 322 is installed at the side end of the second cutting and overlocking bracket 319 and is located between the two columns of fourth horizontal moving guide rails 320. The fourth lead screw nut is fixed on the fourth horizontal moving plate 321. The fourth horizontal lead screw 322 is driven to rotate by a fourth horizontal driving motor installed on the second cutting and overlocking bracket 319, so as to realize the horizontal movement of the fourth horizontal moving plate 321. The extending direction of the fourth horizontal lead screw 322 is the same as the extending direction of the third horizontal moving guide rails 320. For the setting of the fourth horizontal moving mechanism, through the cooperation of the fourth horizontal moving guide rails 320, the fourth horizontal moving plate 321, and the fourth horizontal moving sliders, only one motor is needed to drive the movement, reducing the active driving parts and simplifying the structure.

[0121] A fourth combing mechanism is also installed at the side end of the second overlock sewing machine 319. The fourth combing mechanism has the same structure as the third combing mechanism and will not be elaborated here. For the settings of the third combing mechanism and the fourth combing mechanism, it is to be able to press the yarn bag when using the overlock sewing machine to sew and seal the yarn bag, avoiding the opening of the yarn bag being too large due to cutting and affecting the smooth progress of sewing and sealing.

[0122] The discharging unit includes a discharging conveying support arranged on the side of the second cutting and overedging support 318 away from the first cutting and overedging assembly. A number of discharging conveying rollers are installed on the discharging conveying support and are arranged in parallel along the conveying direction of the sponge. The discharging conveying rollers are driven to rotate by a discharging motor installed on the discharging conveying support. A waste collecting unit is also arranged below the discharging conveying rollers inside the discharging conveying support.

[0123] As Figures 17 - 20 shown in the schematic diagram, the waste collecting unit includes

[0124] a collecting assembly. The collecting assembly includes a pair of collecting boxes 4 arranged in parallel. The two collecting boxes 4 correspond to the first cutting and overedging assembly and the second cutting and overedging assembly one by one, and are respectively located directly below the first cutting and overedging assembly and the second cutting and overedging assembly. The collecting box 4 is a C-shaped trough steel structure with an open upper end, and both sides in the long axis direction of the collecting box 4 are open.

[0125] a storage assembly. The storage assembly includes a storage box 401 arranged beside the collecting assembly. The storage box 401 is a hollow cuboid structure with both ends open, and there is a cavity for temporarily storing waste inside the storage box 401.

[0126] a transmission assembly. The transmission assembly includes a pair of transmission pipes 402 respectively connected to the openings on both sides of the two collecting boxes 4. On the side end of the transmission pipe 402 connected to the collecting box 4, there are also feed ports corresponding to the two collecting boxes 4 one by one. A baffle plate 403 extending horizontally towards the collecting box 4 is also arranged above the feed port on the transmission pipe 402. The baffle plate 403 extends into the collecting box 4, and the height of the baffle plate 403 is lower than the height of the top end of the collecting box 4. For the baffle plate 403 arranged on the transmission pipe 402, when the waste enters the transmission pipe 402 from the collecting box 4, it guides the waste for conveying, avoiding the waste from blocking the feed port on the transmission pipe 402 and affecting the collection of the waste.

[0127] The other sides of the transmission pipes 402 are respectively connected to the openings at both ends of the storage box 401, so that the collecting assembly, the storage assembly, and the transmission assembly form a structure in the shape of a Chinese character 'Ri'. Moreover, after forming such a structure, it also facilitates the overall installation of the entire waste collecting device. An induced draft fan 404 is also installed on one of the transmission pipes 402.

[0128] On the side of the storage bin 401 away from the collection component, there is also a material taking port. A bin door 405 covering the material taking port is also installed on the storage bin 401. In the present invention, the bin door 405 can adopt a push-pull door structure or a hinged door structure. The material taking port and the bin door 405 provided on the storage bin 401 are for opening the bin door after the waste material in the storage bin 401 reaches a certain amount, facilitating personnel to take out the waste material.

[0129] Working principle: Before sponge conveying, first, the pushing cylinder 111 swings upward under the driving action of the swinging cylinder 115 to form a state as shown in Figure 6 the figure. At the same time, the pushing plate 106 is located on the side close to the swinging bracket 113. Then, the sponge is placed on the conveying roller 101 and is driven by the conveying roller 101 to be conveyed along the first conveying direction. When the sponge is conveyed to the corresponding position in the discharging area, the conveying stops. At this time, the sponge is conveyed to the side of the pushing plate 106. The auxiliary conveying belt 108 is driven by the auxiliary conveying motor to work, thereby driving the pushing plate 106 to move towards the discharging side 105, driving the sponge to move along the second conveying direction, and gradually moving out of the conveying roller 101. The sponge is conveyed to the bagging platform beside the loading bracket 1. After the pushing plate 106 is pushed in place, part of the sponge still stays on the conveying roller 101. At this time, the pushing plate 106 retracts. Then, the pushing cylinder 111 swings downward under the driving action of the swinging cylinder 115 until the pushing cylinder 111 swings to the horizontal position. Then, the pushing cylinder 111 works to drive the pushing roller 110 to move along the second conveying direction, thereby using the pushing roller 110 to completely push the sponge out of the loading bracket 1. With the continuous pushing of the pushing cylinder 111, the pushing roller 110 will continue to push the sponge to move onto the lower sleeve bracket 213 and push the sponge to move on the lower sleeve bracket 213 until the sponge is pushed onto the discharging conveying bracket, enabling the sponge to be conveyed by the discharging conveying roller on the discharging conveying bracket. After that, the pushing roller 110 will retract to its original position and wait to convey the next sponge.

[0130] Before the sponge is conveyed on the lower sleeve bracket 213, the yarn bobbin is loaded first. First, according to the length of the sponge to be conveyed and the size of the loaded yarn bobbin, the second motor 210 and the third motor 218 are used to drive the upper sleeve bracket 206 and the lower sleeve bracket 213 to move respectively, so as to adjust the width length of the whole upper sleeve assembly and the lower sleeve assembly. Then, the operator manually sets the yarn bobbin on the outside of the frame formed by the upper sleeve assembly and the lower sleeve assembly. After the setting is completed, the first linkage motor 204 drives the two yarn bobbin loading brackets 2 to move synchronously in the same direction, so as to move the yarn bobbin loading bracket 2 with the set yarn bobbin into the whole sponge automatic bagging system and cooperate with the other components of the sponge automatic bagging system to realize the automatic bagging of the sponge. At the same time, the empty yarn bobbin loading bracket 2 is moved out of the whole sponge automatic bagging system, and the operator manually sets another yarn bobbin on the empty yarn bobbin loading bracket 2 for standby. After the yarn bobbin on the other yarn bobbin loading bracket 2 is used up, the first linkage motor 204 moves the two yarn bobbin loading brackets 2 in the reverse direction to realize the docking of the standby yarn bobbin loading bracket 2, and so on.

[0131] When the yarn bobbin loading bracket 2 with the yarn bobbin moves to the loading position, the sponge will wait on the lower sleeve bracket 213 first. Then, the operator manually pulls the front end of the yarn bobbin and pulls the front end of the yarn bobbin through the first cutting and overedging assembly. The first overedging machine 311 and the first cutting machine 312 are used to overedge and seal the top of the yarn bobbin in sequence to complete the sealing of the front side of the first yarn bag. Then, the upper carding mechanism and the lower carding mechanism start to work, so that the upper carding roller 302 swings downward and the lower carding roller 305 jacks upward, so as to realize the tightening of the yarn bobbin through the cooperation of the upper carding roller 302 and the lower carding roller 305. Then, the upper carding motor 303 and the lower carding motor 308 start to work, so as to drive the upper carding roller 302 and the lower carding roller 305 to start rotating, and the rotating directions of the upper carding roller 302 and the lower carding roller 305 are opposite to the conveying direction of the sponge. By rotating in the opposite direction like this, the flatness of the yarn bobbin is ensured and the wrinkles are reduced. Then, the sponge will enter the yarn bobbin under the conveying of the pushing roller 110. As the sponge is conveyed, the sponge will abut against the sealing position of the front side of the first yarn bag and move the yarn bag further in the direction of the second cutting and overedging assembly. After the sponge pushes the first yarn bag beyond the second cutting and overedging assembly and enters the discharging conveying roller, it stops moving. Then, the second overedging machine 319 and the second cutting machine cut and overedge and seal the untested part of the first yarn bag, so as to form a complete yarn bag and complete the bagging of the first sponge at the same time. At the same time, the first overedging machine 311 and the first cutting machine 312 will cut and overedge and seal the yarn bobbin, so as to complete the sealing of the front side of the second yarn bag and wait for the arrival of the second sponge, and so on. Except that the manual operation is required for the sealing of the front side of the first yarn bag of each yarn bobbin, the rest are all automatic bagging, which greatly reduces the manual labor.

[0132] The bagged sponge is conveyed through the discharging conveying rollers to the entire bagging system, completing the bagging process of the sponge.

[0133] When collecting waste materials, first, the cut waste materials will respectively fall into two collection bins 4. At this time, the induced draft fan 404 starts to work, causing a negative air state to form in the transmission pipeline 402. Since the waste materials themselves are relatively light in weight, they will be pulled by the negative air in the transmission pipeline 402, enter the transmission pipeline 402 from the feed port of the transmission pipeline 402, and pass through the transmission pipeline 402 to enter the storage bin 401, thus realizing the collection of waste materials.

What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
