Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag processing, in particular to a mold fixing structure, which is used for a non-woven bag forming device. Background Art

[0002] With the enhancement of environmental protection awareness, as an environmental protection product, the market demand for non-woven bags is increasing continuously. A non-woven bag is a bag made of non-woven fabric, which is a new type of fiber product with characteristics such as moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic and non-irritating. This material can be naturally decomposed outdoors in 90 days and has a service life of up to 5 years indoors. When burning, it is non-toxic, odorless, and leaves no residues, without polluting the environment.

[0003] For packaging bags with different specifications and shapes, the specifications of the pressing molds required are also different. When the bag body specifications change, the mold specifications need to be replaced. The molds of the forming system are fixed and installed through fasteners. Due to the complex internal structure of the bag-making machine, when replacing the mold, other blocking components need to be disassembled to have enough space for mold disassembly. The disassembly and assembly operations are very troublesome, and the disassembly and assembly methods of the fasteners also require manual operation, which is time-consuming and laborious with low efficiency. For example, the Chinese patent (publication number CN218749641U) discloses an automatic mold-changing mechanism for a bag-making machine. This automatic mold-changing mechanism replaces the mold set on the forming station through a template delivery board. After replacement, the mold will be directly placed on the placement board, but the placement board has no fixing effect on the mold, resulting in the idle mold being prone to tipping. Also, because the mold itself is heavy, there is a great risk of damage to the tipped mold. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the technical problem in the prior art that for a non-woven bag forming machine, for packaging bags with different specifications and shapes, the specifications of the pressing molds required are also different. The removed or to-be-replaced mold will be directly placed on the placement board, resulting in the idle mold being prone to tipping. Also, because the mold itself is heavy, there is a great risk of damage to the tipped mold.

[0005] To solve the above technical problem, an embodiment of the utility model discloses a mold fixing structure for a non-woven bag forming device, wherein the mold is fixedly installed on the installation table through the mold fixing structure.

[0006] One end of the mold protruding along its height direction is provided with a connecting portion and a pair of positioning portions, and the positioning portions are symmetrically located on both sides of the connecting portion in the width direction of the mold.

[0007] The installation table protrudes from the frame of the non-woven bag forming device. Moreover, on the side of the installation table away from the frame, there are fixed components adapted to the connecting part, and a pair of positioning recesses located on both sides of the fixed components in the width direction of the mold and corresponding to the pair of positioning parts respectively.

[0008] Among them, each positioning recess extends inwards from the edge of the installation table; moreover, the mold translates relative to the installation table in a direction perpendicular to the height direction of the mold, the positioning part slides into the corresponding positioning recess, the fixed component moves along the height direction of the mold and is fixedly connected to the connecting part of the mold, and the mold is fixedly connected to the installation table in a suspended manner.

[0009] With the above technical solution, the mold used for production on the non-woven bag forming device is disassembled and can be fixed on the installation table through the mold fixing structure. Among them, the two positioning parts on both sides of the connecting part of the mold along the width of the mold can slide into the corresponding positioning recesses on the installation table relative to the installation table in a direction perpendicular to the height direction of the mold, and the fixed component on the installation table can move along the height direction of the mold and be fixedly connected to the connecting part of the mold. Thus, the idle mold is connected to the installation table in a suspended manner.

[0010] Therefore, this installation table can fixedly connect the mold in a suspended manner through the above mold fixing structure, avoid the mold from colliding with other components, reduce the risk of damage to the mold, and when the mold is disassembled from the installation table, the connection between the fixed component and the connecting part on the mold can be disconnected first, and by sliding the positioning part out of the positioning recess in a direction perpendicular to the height direction of the mold, that is, this mold fixed connection structure can not only ensure that the mold is firmly assembled to the installation table, but also is convenient for disassembly and assembly, which is beneficial for the non-woven bag forming device to change the mold.

[0011] An embodiment of the present utility model discloses a mold fixing structure of a non-woven bag forming device. When the mold is suspended and connected to the installation table, the height direction of the mold is parallel to the vertical direction, the positioning part and the connecting part are arranged at the upper end of the mold, and the height of each positioning part protruding from the upper end face of the mold is greater than the height of the connecting part protruding from the upper end face of the mold.

[0012] Moreover, the installation table is in a plate-like structure extending in the horizontal direction, and one side edge thereof is connected to the frame; and when the mold is suspended and connected to the installation table, the pair of positioning parts of the mold are respectively clamped in the corresponding positioning recesses, and the connecting part is located below the fixed component and is fixedly connected to the fixed component.

[0013] By adopting the above technical solution, the mold is suspended in the vertical direction and connected to the mounting platform, so as to avoid the risk of tilting when the mold is assembled on the mounting platform, and improve the assembly stability between the mounting platform and the mold. In addition, the height of each positioning part protruding from the upper end surface of the mold is greater than the height of the connecting part protruding from the upper end surface of the mold. When the positioning part of the mold slides into the positioning recess on the mounting platform in the horizontal direction, the connecting part will not collide with the mounting platform of the plate-like structure, and is fixedly connected with the connecting part below by the fixing assembly.

[0014] Therefore, under the premise that the positioning portion of the mold avoids the mounting platform, the mounting platform set as a plate-like structure has a higher structural strength and can better support the mold.

[0015] The embodiment of the utility model discloses a mold fixing structure of a non-woven bag forming device, wherein the fixing assembly comprises a fixing driving part arranged on a side of a mounting platform away from the mold, and a fixing member arranged on a side of the mounting platform close to the mold and transmission-connected to the fixing driving part.

[0016] The fixing member can move in a vertical direction relative to the mounting platform, and the fixing driving member drives the lower end of the fixing member to be detachably connected to the connecting portion of the mold.

[0017] By adopting the above technical solution, the fixed driving part is arranged on the side of the mounting platform away from the mounting platform, and only the fixed component is arranged on the side of the mounting platform close to the mold, so as to avoid the fixed component occupying too much space on the lower side of the mounting platform. When the fixed component is connected to the connecting part of the mold, the fixed component can move in the vertical direction relative to the mounting platform, and then can be assembled with the connecting part below.

[0018] The embodiment of the utility model discloses a mold fixing structure of a non-woven bag forming device, wherein the connecting part comprises a connecting pin protrudingly arranged at one end of the mold, the connecting pin having a connecting pin rod fixed to the mold at one end, and a connecting pin head located at the free end of the connecting pin rod.

[0019] Among them, the fixed driving part is a driving cylinder, and the fixed component is set as a chuck compatible with the connecting pin head; and a telescopic component is also arranged between the chuck and the mounting table, the telescopic component extends in the vertical direction, and the chuck is arranged at the end of the telescopic component away from the mounting table and can move in the vertical direction; and when the mold is suspended on the mounting table, the driving cylinder links the chuck to clamp the connecting pin head embedded in the chuck.

[0020] With the above technical solution, when the positioning part of the mold is located within the corresponding positioning recess, at this time, the connecting pin of the mold is located below the chuck. Under the linkage of the telescopic member, the chuck moves downward in the vertical direction until the connecting pin head on the connecting pin is located within the chuck. Then, the driving cylinder drives the chuck to clamp the connecting pin head embedded in the chuck, thereby better fixing the mold and improving the connection strength between the mounting table and the mold. When the mold on the mounting table needs to be disassembled, the driving cylinder drives the chuck to release the connecting pin head, and the chuck retracts upward under the linkage of the telescopic member, providing clearance for the mold to slide out of the mounting table in the horizontal direction.

[0021] An embodiment of the present utility model discloses a mold fixing structure for a non-woven bag forming device. Each positioning part includes a positioning pin disposed beside the connecting pin. The positioning pin has a positioning pin rod fixed at one end to the mold and a positioning pin head provided at the free end of the positioning pin rod.

[0022] Among them, each positioning recess includes a positioning through-hole and a guiding groove. The positioning through-hole penetrates the mounting table and is adapted to the size of the positioning pin rod. A counterbore adapted to the positioning pin head is formed at the upper edge of the positioning through-hole; the guiding groove penetrates the mounting table and extends from the outer edge of the mounting table to the positioning through-hole parallel to the translation direction of the mold, and the width is adapted to the size of the corresponding positioning pin rod.

[0023] With the above technical solution, the guiding groove of the positioning recess can provide a guiding function for the positioning pin rod on the mold to be assembled into the positioning through-hole, ensuring that the positioning pin rod can accurately slide from the edge of the mounting table and be assembled into the positioning through-hole. Further, a counterbore adapted to the positioning pin head is formed at the upper edge of the positioning through-hole. When the positioning pin rod is located within the corresponding positioning through-hole, the positioning pin head on the positioning pin will be assembled into the counterbore, restricting the mold from shaking relative to the mounting table, thereby improving the assembly accuracy between the mold and the mounting table.

[0024] An embodiment of the present utility model discloses a mold fixing structure for a non-woven bag forming device. An assembly plate extending in the vertical direction is provided at one side edge of the mounting table close to the frame, and the assembly plate is slidably assembled to the frame in the vertical direction.

[0025] With the above technical solution, by providing the assembly plate at one side edge of the mounting table, the connection strength between the mounting table and the frame can be improved, and the assembly plate can slide relative to the frame in the vertical direction, enabling the position of the mounting table on the frame to be arranged more flexibly, thereby making clearance for the movement of other components on the frame. Moreover, when the mounting table moves in the vertical direction, the mold connected to the mounting table is not prone to shaking.

[0026] An embodiment of the present utility model discloses a mold fixing structure for a non-woven bag forming device. A reinforcing rib plate extending in the vertical direction is formed between the assembly plate and the mounting table.

[0027] With the above technical solution, by providing a reinforcing rib plate between the assembly plate and the mounting table, the connection strength between the assembly plate and the mounting table is improved. At the same time, since the reinforcing rib plate extends in the vertical direction, the ability of the mounting table to carry the mold can also be increased.

[0028] An embodiment of the present utility model discloses a non-woven bag forming device, which includes a mold lifting component and a mold replacement component arranged on a frame.

[0029] The mold lifting component is linked to the mold thereon and performs non-woven bag forming processing in the vertical direction. A mold connecting member detachably connecting the mold is provided at the lower end of the mold lifting component, and the mold is linked to move in the vertical direction; wherein, a connecting portion and a pair of positioning portions are prominently provided at one end of the mold in the height direction thereof. The positioning portions are symmetrically located on both sides of the connecting portion in the width direction of the mold. The mold connecting member is detachably connected to both the connecting portion and the positioning portion of the mold at the same time.

[0030] The mold replacement component can drive the mold to move between the mold storage area and the mold lifting component and replace the mold connected to the mold lifting component; wherein, the mold storage area includes a plurality of mounting tables horizontally arranged on the frame, and each mounting table is fixedly connected to the mold stored thereon through any one of the above mold fixing structures; and, the mold replacement component includes a movable clamping component arranged between the plurality of mounting tables and the mold connecting member. The clamping component can move the mold stored on the mounting table to the mold lifting component or move the mold from the mold lifting component to the corresponding mounting table.

[0031] With the above technical solution, the mold lifting component of this non-woven bag forming device can drive the mold thereon to move in the vertical direction, so as to realize the forming processing of the non-woven bag. When the mold specifications need to be changed due to the change of the bag body specifications, the clamping component of the mold replacement component is used to drive the mold to move between the mold connecting member of the mold lifting component and any one of the mounting tables located in the mold storage area. The mold connected to the mounting table is moved by the clamping component and connected to the mold connecting member for production, while the mold on the mold connecting member will be disassembled and connected to the mounting table. By matching the connecting portion and the positioning portion with the fixing component and the positioning recess on the mounting table respectively, it is ensured that the disassembled mold can be stably connected to the mounting table, reducing the risk of the mold tipping or shaking. And, the mold installed on the mounting table through the mold fixing structure has the advantage of convenient disassembly and assembly, which is conducive to quick mold change on the premise of ensuring the assembly stability of the mold.

[0032] An embodiment of the present utility model discloses a non-woven bag forming device, and each mounting table is slidably arranged on a corresponding transport rail on the frame.

[0033] Moreover, the mounting table can at least stop at a position on the transport rail that is flush with the mold connecting member in the vertical direction, and the mold stored on the mounting table is translated to the mold lifting member by the clamping member, or the mold is translated from the mold lifting member to the corresponding mounting table.

[0034] With the above technical solution, each mounting table is slidably arranged on the transport rail, so that the position of the mounting table on the frame can be adjusted flexibly. When the mounting table stops at a position on the transport rail that is flush with the mold connecting member in the vertical direction, the clamping member replaces the mold between the mold connecting member and the mounting table in a horizontally translated manner. When the clamping member drives the mold to move, the height direction of the mold will not be changed, which is more conducive to assembling the mold to the mold connecting member or the mounting table.

[0035] An embodiment of the present utility model discloses a non-woven bag forming device. The mold replacement assembly further includes a guiding member, and the clamping member is movably arranged on the guiding member.

[0036] Among them, the guiding member includes a first guide rail extending along a first direction between the mold connecting member and multiple mounting tables, and a second guide rail extending along a second direction passing through the multiple mounting tables.

[0037] One end of the first guide rail corresponds to the mold connecting member, the other end is connected to the second guide rail, and the first guide rail can move along the second guide rail in the second direction. The clamping member is arranged on the first guide rail and can move relative to the first guide rail in the first direction. Among them, both the first direction and the second direction are perpendicular to the vertical direction and perpendicular to each other.

[0038] With the above technical solution, during the mold replacement process, the clamping member moves along the guiding component between the mold connecting member and multiple mounting tables. For example, during the mold unloading process, the clamping member moves the mold removed from the mold connecting member along the first guide rail to the mold storage area. Further, the first guide rail moves along the second guide rail, and the clamping member on the first guide rail corresponds to the mounting table for connecting the mold, and the mounting table loads the removed mold; during the mold loading process, the first guide rail moves along the second guide rail, and the clamping member on the first guide rail corresponds to the mounting table for connecting the mold to be replaced. The clamping member clamps the mold to be replaced, then the first guide rail moves along the second guide rail, and one end of the first guide rail corresponds to the mold connecting member. The clamping member transports the mold to be replaced along the first guide rail to the mold connection position of the mold connecting member, and the mold connecting member connects the mold to be replaced to complete the mold replacement.

[0039] An embodiment of the present utility model discloses a non-woven bag forming device. In the second direction, multiple mounting tables are arranged in pairs at both ends of the second guide rail. Moreover, the transport rail extends in the vertical direction or extends in an arc in the vertical plane.

[0040] With the above technical solution, multiple mounting tables are arranged in pairs at both ends of the second guide rail. When changing the mold, the clamping component can move the mold on the mold connecting piece to the mounting table at one end of the second guide rail, and move the mold on the mounting table at the other end of the second guide rail to the mold connecting piece. That is, the mounting table at any end of the second guide rail can be used to mount the mold disassembled from the mold connecting piece, and the mounting table at the other end bears the mold to be replaced, so as to achieve the purpose of mold change without increasing the space occupied by the non-woven bag forming device in the second direction.

[0041] When the mounting table is connected to the mold, in order to improve the connection stability between the mounting table and the mold, the mounting table can be moved downward along the transport rail until the bottom of the mold contacts the base of the machine frame or the ground, so as to assist in supporting the mold. This can not only reduce the bearing capacity of the mounting table for connecting the mold, but also make the mold more stably assembled on the mounting table. Among them, the transport rail extending in the vertical direction has good stability during the transportation of the mounting table, avoiding the mold on the mounting table from shaking during the movement. And the transport rail extending in an arc in the vertical plane can transport the mounting table along the arc, making the movement path of the mounting table more flexible and allowing it to avoid other components on the machine frame.

[0042] The beneficial effects of the present utility model are as follows:

Among them, the mold is fixedly installed on the mounting table through the mold fixing structure.

On the side of the mounting table away from the machine frame, there is a fixing component adapted to the connecting portion, and a pair of positioning concave portions arranged on both sides of the fixing component in the width direction of the mold and corresponding to the pair of positioning portions respectively. Each positioning concave portion extends inward from the edge of the mounting table; and the mold translates relative to the mounting table perpendicular to the height direction of the mold, the positioning portion slides into the corresponding positioning concave portion, the fixing component moves along the height direction of the mold and is fixedly connected to the connecting portion of the mold, and the mold is fixedly connected to the mounting table in a suspended manner, avoiding the idle mold from colliding with other components and reducing the risk of damage to the mold. Moreover, this mold fixing connection structure can not only ensure that the mold is firmly assembled to the mounting table, but also is convenient for disassembly and assembly, which is beneficial for the non-woven bag forming device to change the mold.

[0044] Furthermore, the present utility model also discloses a non-woven bag forming device. The mold lifting component of this non-woven bag forming device can drive the mold connected thereto to move in the vertical direction, thereby realizing the forming process of the non-woven bag.

[0076] The production of non-woven fabric three-dimensional bags generally relies on the one-time forming process of a three-dimensional bag forming machine. In this process, the die lifting device plays a crucial role and can link the die to press the flat non-woven fabric into the required cuboid shape. However, in the face of diverse size and specification requirements in the market, due to the large volume, heavy weight, and fixed structure of traditional dies, it is necessary to frequently replace the dies when producing three-dimensional bags of different sizes. This not only increases the production cost but also seriously affects the production efficiency and flexibility due to the complexity and time-consuming nature of die replacement.

[0077] There are also automatic die-changing mechanisms in the prior art. Such die-changing mechanisms replace the die on the forming component through a die-feeding component. During the replacement process, the removed die is simply placed on a placement board, but the placement board itself is not designed with any structural board for fixing the die. This leads to a potential problem: the unfixed die is prone to tipping due to external factors (such as slight collisions, wind, etc.). Considering the large weight of the die itself, once it tips over, it may not only cause serious damage to the die itself but also pose a safety hazard to the surrounding equipment and personnel.

[0078] Therefore, the present utility model discloses a die fixing structure for a non-woven bag forming device. The die can be connected to the installation table through the die fixing structure. Among them, one end of the die protruding along its height direction Z is provided with a connecting portion and a pair of positioning portions. The positioning portions are symmetrically located on both sides of the connecting portion in the width direction of the die. The installation table is provided with a fixing component adapted to the connecting portion, and a pair of positioning recesses located on both sides of the fixing component in the width direction of the die and corresponding to the pair of positioning portions respectively. Each positioning recess extends inward from the edge of the installation table; and, the die translates relative to the installation table perpendicular to the height direction of the die, the positioning portion slides into the corresponding positioning recess, the fixing component moves along the height direction of the die and is fixedly connected to the connecting portion of the die, and the die is fixedly connected to the installation table in a suspended manner.

[0079] This die fixed connection structure can not only ensure that the die is firmly assembled to the installation table, but also is convenient for disassembly and assembly, which is beneficial for the non-woven bag forming device to change the die.

[0080] To make the purpose, technical solution, and advantages of the present utility model clearer, the following will further describe the embodiments of the present utility model in detail with reference to the accompanying drawings.

[0081] As Figures 1-8 shown, the embodiment of the present utility model provides a die fixing structure for a non-woven bag forming device, wherein the die 300 is fixedly installed on the installation table 400 through the die fixing structure.

[0082] One end of the mold 300 protrudes along its height direction Z and is provided with a connecting portion 310 and a pair of positioning portions 320. The positioning portions 320 are symmetrically located on both sides of the connecting portion 310 in the width direction of the mold 300.

[0083] The installation table 400 protrudes from the frame of the non-woven bag forming device 10 (not shown in the figure). Moreover, a fixing assembly 410 adapted to the connecting portion 310 is provided on one side of the installation table 400 away from the frame, and a pair of positioning recesses 420 located on both sides of the fixing assembly 410 in the width direction of the mold 300 and corresponding to the pair of positioning portions 320 respectively are provided.

[0084] Wherein, each positioning recess 420 extends inwards from the edge of the installation table; moreover, the mold 300 translates relative to the installation table 400 along a direction perpendicular to the height direction Z of the mold 300, the positioning portion 320 slides into the corresponding positioning recess 420, the fixing assembly 410 moves along the height direction Z of the mold 300 and is fixedly connected to the connecting portion 310 of the mold 300, and the mold 300 is fixedly connected to the installation table 400 in a suspended manner.

[0085] This mold fixing structure is used on the non-woven bag forming device 10, so that the mold 300 for production on the non-woven bag forming device 10 can be disassembled and fixed on the installation table 400 through the mold fixing structure. Among them, the two positioning portions 320 on both sides of the connecting portion 310 of the mold 300 in the width direction of the mold 300 can slide into the corresponding positioning recesses 420 on the installation table 400 along a direction perpendicular to the height direction Z of the mold 300, and the fixing assembly 410 on the installation table 400 can move along the height direction Z of the mold 300 and is fixedly connected to the connecting portion 310 of the mold 300. Thus, the idle mold 300 is connected to the installation table 400 in a suspended manner.

[0086] Therefore, this installation table 400 can fixedly connect the mold 300 in a suspended manner through the above-mentioned mold fixing structure, avoid the mold 300 from colliding with other components, reduce the risk of damage to the mold 300, and when the mold 300 is disassembled from the installation table 400, the connection between the fixing assembly 410 and the connecting portion 310 on the mold 300 can be disconnected first, and the positioning portion 320 can be slid out of the positioning recess 420 along a direction perpendicular to the height direction Z of the mold 300, that is, this mold fixing connection structure can not only ensure that the mold 300 is firmly assembled to the installation table 400, but also is convenient for disassembly and assembly, which is beneficial to the mold change of the non-woven bag forming device 10.

[0087] Specifically, when the mold 300 is suspended and connected to the mounting table 400, the height direction Z of the mold 300 is parallel to the vertical direction, the positioning portion 320 and the connecting portion 310 are arranged at the upper end of the mold 300, and the height of each positioning portion 320 protruding from the upper end surface of the mold 300 is greater than the height of the connecting portion 310 protruding from the upper end surface of the mold 300.

[0088] Furthermore, the mounting platform 400 is a plate-like structure extending in a horizontal direction, and one side edge of the structure is connected to the frame; and when the mold 300 is suspended and connected to the mounting platform 400, a pair of positioning portions 320 of the mold 300 are respectively engaged in corresponding positioning recesses 420, and the connecting portion 310 is located below the fixing component 410 and is fixedly connected to the fixing component 410.

[0089] In this embodiment, the mold 300 is suspended and connected to the mounting platform 400 in the vertical direction, so as to avoid the risk of tilting when the mold 300 is assembled on the mounting platform 400, and improve the assembly stability between the mounting platform 400 and the mold 300. In addition, the height of each positioning portion 320 protruding from the upper end surface of the mold 300 is greater than the height of the connecting portion 310 protruding from the upper end surface of the mold 300. When the positioning portion 320 of the mold 300 slides into the positioning recess 420 on the mounting platform 400 in the horizontal direction, the connecting portion 310 will not collide with the mounting platform 400 of the plate-like structure, and is fixedly connected to the connecting portion 310 below by the fixing assembly 410.

[0090] Therefore, under the premise that the positioning portion 320 of the mold 300 avoids the mounting platform 400 , the mounting platform 400 which is set as a plate-like structure has a higher structural strength and can better support the mold 300 .

[0091] In another alternative embodiment, the height of each positioning portion 320 protruding from the upper end surface of the mold 300 is equal to the height of the connecting portion 310 protruding from the upper end surface of the mold 300, and the portion of the mounting table 400 on which the fixing component 410 is provided protrudes upward in the vertical direction, so that when the positioning portion 320 of the mold 300 slides along the positioning recess 420 of the mounting table 400 in the horizontal direction, the fixing component 410 can avoid the connecting portion 310 on the mold 300. Of course, the height of each positioning portion 320 protruding from the upper end surface of the mold 300 may also be greater than the height of the connecting portion 310 protruding from the upper end surface of the mold 300, and this embodiment does not make any specific limitation on this.

[0092] Furthermore, if Figure 2 As shown, in this embodiment, the fixing assembly 410 includes a fixing driving member 411 disposed on the side of the mounting platform 400 away from the mold 300 , and a fixing component 412 disposed on the side of the mounting platform 400 close to the mold 300 and transmission-connected to the fixing driving member 411 .

[0093] The fixing member 412 can move in a vertical direction relative to the mounting table 400 , and the fixing driving member 411 drives the lower end of the fixing member 412 to be detachably connected to the connecting portion 310 of the mold 300 .

[0094] Since the fixed driving member 411 is arranged on the side away from the mounting platform 400, and only the fixed component 412 is arranged on the side of the mounting platform 400 close to the mold 300, it is avoided that the fixed component 410 occupies too much space on the lower side of the mounting platform 400. When the fixed component 412 is connected to the connecting part 310 of the mold 300, the fixed component 412 can move in the vertical direction relative to the mounting platform 400, and can then be assembled with the connecting part 310 below.

[0095] The mold fixing structure is described in detail below in conjunction with the mold 300 and the mounting platform 400 .

[0096] like Figure 1 As shown, in this embodiment, the connecting portion 310 includes a connecting pin 311 protruding from one end of the mold 300 , and the connecting pin 311 has a connecting pin rod 312 fixed to the mold 300 at one end, and a connecting pin head 313 located at the free end of the connecting pin rod 312 .

[0097] Among them, the fixed driving part 411 is a driving cylinder, and the fixed component 412 is configured as a chuck compatible with the connecting pin head 313; and a telescopic component is also arranged between the chuck and the mounting platform 400, the telescopic component extends in the vertical direction, and the chuck is arranged at the end of the telescopic component away from the mounting platform 400 and can move in the vertical direction; and when the mold 300 is suspended on the mounting platform 400, the driving cylinder links the chuck to clamp the connecting pin head 313 embedded in the chuck.

[0098] When the positioning portion 320 of the mold 300 is located in the corresponding positioning recess 420, the connection pin 311 of the mold 300 is located below the chuck. The chuck moves downward in the vertical direction under the linkage of the telescopic component until the connection pin head 313 on the connection pin 311 is located in the chuck. The driving cylinder links the chuck to clamp the connection pin head 313 embedded in the chuck, thereby better fixing the mold 300 and improving the connection strength between the mounting platform 400 and the mold 300. When the mold 300 on the mounting platform 400 needs to be removed, the driving cylinder links the chuck to release the connection pin head 313, and the chuck retracts upward under the linkage of the telescopic component, providing a clearance for the mold 300 to slide out of the mounting platform 400 in the horizontal direction.

[0099] In another alternative embodiment, the fixing member 412 may be provided as a jaw, which can grip the pin head 313 of the connecting pin 311 in the vertical direction. Of course, it can also grip the pin rod 312 of the connecting pin 311 in the horizontal direction. This embodiment does not make specific limitations in this regard. Moreover, the connecting portion 310 on the mold 300 does not necessarily have to be provided as a pin-shaped structure. It can be other special-shaped structures protruding from the upper end face of the mold 300, as long as the edge of this structure can be clamped and fixed. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations in this regard.

[0100] Further, as Figures 1-4 shown, in this embodiment, each positioning portion 320 includes a positioning pin 321 disposed beside the connecting pin 311. The positioning pin 321 has a pin rod 322 fixed to the mold 300 at one end and a pin head 323 disposed at the free end of the pin rod 322.

[0101] Among them, each positioning recess 420 includes a positioning through hole 421 and a guiding groove 423. Among them, the positioning through hole 421 penetrates through the mounting table 400 and is adapted to the size of the pin rod 322. A counterbore 422 adapted to the pin head 323 is formed at the upper end edge of the positioning through hole 421; the guiding groove 423 penetrates through the mounting table 400 and extends from the outer edge of the mounting table 400 to the positioning through hole 421 parallel to the translation direction of the mold 300, and the width is adapted to the size of the corresponding pin rod 322.

[0102] Specifically, the guiding groove 423 of the positioning recess 420 can provide a guiding function for the pin rod 322 on the mold 300 to be assembled into the positioning through hole 421, ensuring that the pin rod 322 can accurately slide from the edge of the mounting table 400 and be assembled into the positioning through hole 421. Further, a counterbore 422 adapted to the pin head 323 is formed at the upper end edge of the positioning through hole 421. When the pin rod 322 is located in the corresponding positioning through hole 421, the pin head 323 on the positioning pin 321 will be assembled into the counterbore 422, restricting the mold 300 from shaking relative to the mounting table 400, thereby improving the assembly accuracy between the mold 300 and the mounting table 400.

[0103] In another embodiment, the positioning portion 320 is disposed on the side wall surface of the mold 300 to form a limiting portion 330 extending outward along the direction Z perpendicular to the height direction of the mold 300. The side edge of the mounting table 400 forms a blind hole adapted to the limiting portion 330. When the mold 300 is connected to the mounting table 400, the limiting portion 330 on the side wall surface of the mold 300 can extend into the blind hole on the mounting table 400, so that the mounting table 400 can be suspended and connected to the mold 300. Therefore, regarding the specific structures of the positioning portion 320 and the positioning concave portion 420, as long as the mounting table 400 can be suspended and connected to the mold 300, those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations thereon.

[0104] As Figure 2 and Figure 8 shown, in this embodiment, an assembly plate 430 extending in the vertical direction is provided at a side edge of the mounting table 400 close to the frame. The assembly plate 430 is slidably assembled to the frame in the vertical direction. By providing the assembly plate 430 at a side edge of the mounting table 400, the connection strength between the mounting table 400 and the frame can be improved, and the assembly plate 430 can slide relative to the frame in the vertical direction, enabling the position of the mounting table 400 on the frame to be arranged more flexibly, so as to make way for the movement of other components on the frame. Moreover, when the mounting table 400 moves in the vertical direction, the mold 300 connected to the mounting table 400 is not likely to shake.

[0105] Furthermore, as Figure 2 shown, in order to improve the connection strength between the assembly plate 430 and the mounting table 400, a reinforcing rib plate 401 extending in the vertical direction is formed between the assembly plate 430 and the mounting table 400. At the same time, since the reinforcing rib plate 401 extends in the vertical direction, the ability of the mounting table 400 to carry the mold 300 can also be increased.

[0106] More specifically, as Figure 2 shown, in this embodiment, the assembly plate 430 extends downward in the vertical direction relative to the mounting table 400, and two reinforcing rib plates 401 are provided at intervals in the horizontal direction between the assembly plate 430 and the mounting table 400. Of course, one, three or four can also be provided, and the present invention does not make specific limitations thereon.

[0107] In summary, the present utility model provides a mold fixing structure for a non-woven bag forming device 10. This mold fixing structure mainly slides the positioning portion 320 on the mold 300 into the positioning recess 420 of the mounting table 400, and fixes the connecting portion 310 on the mold 300 through the fixing member 412 on the mounting table 400. Thus, on the premise of ensuring the stable assembly of the mounting table 400 and the mold 300, the mounting table 400 is convenient for disassembling and assembling the mold 300, thereby reducing the difficulty of mold replacement for the non-woven bag forming device 10. Regarding the mold fixing structure, it is not limited to the structure in the above embodiment, and those skilled in the art can design according to the actual situation and specific requirements. This embodiment does not make specific limitations in this regard.

[0108] As Figures 5-8 shown, the present utility model also provides a non-woven bag forming device 10, including a mold lifting component 100 and a mold replacement component 200 provided on a frame.

[0109] The mold lifting component 100 is linked to the mold 300 thereon to perform non-woven bag forming processing in the vertical direction. A mold connecting member 110 for detachably connecting the mold 300 is provided at the lower end of the mold lifting component 100, and the mold 300 is linked to move in the vertical direction; wherein, at one end of the mold 300 along its height direction Z, a connecting portion 310 and a pair of positioning portions 320 are prominently provided. The positioning portions 320 are symmetrically located on both sides of the connecting portion 310 in the width direction of the mold 300. The mold connecting member 110 is detachably connected to both the connecting portion 310 and the positioning portion 320 of the mold 300.

[0110] The mold replacement component 200 can drive the mold 300 to move between the mold storage area and the mold lifting component 100, and replace the mold 300 connected to the mold lifting component 100; wherein, the mold storage area includes a plurality of mounting tables 400 arranged horizontally on the frame, and each mounting table 400 is fixedly connected to the mold 300 stored thereon through any one of the above mold fixing structures; and, the mold replacement component 200 includes a movable clamping component 210 provided between the plurality of mounting tables 400 and the mold connecting member 110. The clamping component 210 can move the mold 300 stored on the mounting table 400 to the mold lifting component 100, or move the mold 300 from the mold lifting component 100 to the corresponding mounting table 400.

[0111] The mold lifting component 100 of this non-woven bag forming device 10 can drive the mold 300 connected thereto to move in the vertical direction, thereby realizing the forming process of the non-woven bag. When the bag body specifications change and the mold specifications need to be replaced, the clamping component 210 of the mold replacement component 200 is used to drive the mold 300 to move between the mold connecting member 110 of the mold lifting component 100 and any one of the mounting tables 400 located in the mold storage area. The mold 300 connected to the mounting table 400 is moved by the clamping component 210 and connected to the mold connecting member 110 for production, while the mold 300 on the mold connecting member 110 will be disassembled and connected to the mounting table 400. By the cooperation of the connecting portion 310 and the positioning portion 320 with the fixing component 410 and the positioning recess 420 on the mounting table 400 respectively, it is ensured that the disassembled mold 300 can be firmly connected to the mounting table 400, reducing the risk of the mold 300 tipping or shaking. Moreover, the mold 300 installed on the mounting table 400 through the mold fixing structure has the advantage of being convenient to disassemble and assemble. On the premise of ensuring the assembly stability of the mold 300, it is beneficial to perform quick mold change.

[0112] As Figure 5 and Figure 6 shown, in this embodiment, the clamping component 210 of the non-woven bag forming device 10 is movably arranged on the guiding component 220.

[0113] Among them, the guiding component 220 includes a first guide rail 221 extending along the first direction Y between the mold connecting member 110 and the plurality of mounting tables 400, and a second guide rail 223 extending along the second direction X passing through the plurality of mounting tables 400.

[0114] One end of the first guide rail 221 corresponds to the mold connecting member 110, and the other end is connected to the second guide rail 223. And the first guide rail 221 can move along the second guide rail 223 in the second direction X. The clamping component 210 is arranged on the first guide rail 221 and can move relative to the first guide rail 221 in the first direction Y. Among them, both the first direction Y and the second direction X are perpendicular to the vertical direction and perpendicular to each other.

[0115] During the die change process, the clamping member 210 moves along the guiding assembly between the die connecting member 110 and the plurality of mounting platforms 400. For example, during the die removal process, the clamping member 210 moves the die 300 removed from the die connecting member 110 along the first guide rail 221 to the die storage area. Further, the first guide rail 221 moves along the second guide rail 223, and the clamping member 210 on the first guide rail 221 is made to correspond to the mounting platform 400 not connected to the die 300, and the mounting platform 400 loads the removed die 300; during the die installation process, the first guide rail 221 moves along the second guide rail 223, and the clamping member 210 on the first guide rail 221 is made to correspond to the mounting platform 400 connected to the die 300 to be replaced. The clamping member 210 clamps the die 300 to be replaced. Then the first guide rail 221 moves along the second guide rail 223, and one end of the first guide rail 221 is made to correspond to the die connecting member 110. The clamping member 210 transports the die 300 to be replaced along the first guide rail 221 to the die connection position of the die connecting member 110, and the die connecting member 110 connects the die 300 to be replaced, completing the die change.

[0116] And, as Figure 5 shown, in the second direction X, the plurality of mounting platforms 400 are arranged in pairs at both ends of the second guide rail 223. The plurality of mounting platforms 400 are arranged in pairs at both ends of the second guide rail 223. During die change, the clamping member 210 can move the die 300 on the die connecting member 110 to the mounting platform 400 at one end of the second guide rail 223, and move the die 300 on the mounting platform 400 at the other end of the second guide rail 223 to the die connecting member 110. That is, the mounting platform 400 at any one end of the second guide rail 223 can be used to mount the die 300 removed from the die connecting member 110, and the mounting platform 400 at the other end bears the die 300 to be replaced, thus achieving the purpose of die change. And, the length of the second guide rail 223 in the second direction X does not exceed the width of the frame, that is, the length of the second guide rail 223 is less than the width of the frame, or the length of the second guide rail 223 is equal to the width of the frame, so as not to increase the space occupied by the non-woven bag forming device 10 in the second direction X.

[0117] Furthermore, as Figure 7As shown, in this embodiment, the clamping member 210 includes a clamping plate 211 provided with a clamping groove, and a sliding plate 213 slidably connected to the first guide rail 221. A first driving member 222 and an angle adjusting member 214 are provided on the sliding plate 213. It should be noted that the clamping groove on the clamping plate 211 is adapted to the side wall surface of the mold 300. Moreover, on the side wall surface of the mold 300, a plurality of limiting portions 330 are arranged at intervals in the circumferential direction, and on the periphery of the clamping groove of the clamping plate 211, a plurality of limiting recesses 212 corresponding to and adapted to the limiting portions 330 are formed. When the mold 300 is clamped in the clamping groove of the pre-clamping plate 211, the limiting portions 330 on the side wall of the mold 300 are respectively inserted into the corresponding limiting recesses 212 to clamp the mold 300.

[0118] Among them, on the first guide rail 221, a first rack 226 extending along the first direction Y is provided; the output end of the first driving member 222 is in transmission connection with the first rack 226, and the first driving member 222 drives the sliding plate 213 to move along the first direction Y.

[0119] The angle adjusting member 214 is in transmission connection with the clamping plate 211, and the angle adjusting member 214 drives the clamping plate 211 to rotate around the vertical direction relative to the sliding plate 213 to adjust the opening direction of the clamping groove.

[0120] As Figure 6 shown, in this embodiment, the guiding member 220 further includes an auxiliary guide rail 224 parallel to and spaced from the second guide rail 223, and one end of the first guide rail 221 is connected to the auxiliary guide rail 224.

[0121] Among them, a second driving member 225 is provided at one end of the first guide rail 221, and a second rack 227 extending along the second direction X is provided on the auxiliary guide rail 224. The output end of the second driving member 225 is in transmission connection with the second rack 227, and the second driving member 225 drives the first guide rail 221 to translate along the second direction X relative to the second guide rail 223 and the auxiliary guide rail 224. It should be noted that, in this embodiment, the first driving member 222, the second driving member 225, and the angle adjusting member 214 can all be set as servo motors. Since the servo motor has a high control precision, it can better and accurately control the movement of the clamping member 210. Of course, the present invention does not make a unique limitation on this.

[0122] Furthermore, in this embodiment, each mounting table 400 is slidably disposed on a corresponding transport rail 500 on the frame. And the mounting table 400 is driven by a transport driving member 510 so that the mounting table 400 can move along the extending direction of the transport rail 500. The transport driving member 510 can be a commonly used servo motor in the art. On the side of the mounting plate 430 of the mounting table 400 close to the frame, a slider (not shown in the figure) adapted to and connected to the transport rail 500 is formed, and the transport driving member 510 is connected to the mounting plate 430 through belt drive. Of course, it can also be other commonly used driving methods in the art, and the present utility model does not make a unique limitation thereto.

[0123] Moreover, the mounting table 400 can at least stop at a position on the transport rail 500 that is flush with the mold connecting member 110 in the vertical direction, and the mold 300 stored on the mounting table 400 is translated to the mold lifting member 100 or the mold 300 is translated from the mold lifting member 100 to the corresponding mounting table 400 through the clamping member 210.

[0124] It should be noted that the transport rail 500 is formed on the frame and extends in the vertical direction. Since each mounting table 400 is slidably disposed on the transport rail 500, the position of the mounting table 400 on the frame can be flexibly adjusted. When the mounting table 400 stops at a position on the transport rail 500 that is flush with the mold connecting member 110 in the vertical direction, the clamping member 210 replaces the mold 300 between the mold connecting member 110 and the mounting table 400 in a horizontal translation manner. When the clamping member 210 drives the mold 300 to move, the height direction Z of the mold 300 will not be changed, which is more conducive to assembling the mold 300 to the mold connecting member 110 or the mounting table 400.

[0125] When the mounting table 400 is connected to the mold 300, in order to improve the connection stability between the mounting table 400 and the mold 300, the mounting table 400 can be disposed on the transport rail 500 extending in the vertical direction. The mounting table 400 moves downward along the transport rail 500 until the bottom of the mold 300 contacts the base of the frame or the ground, thereby assisting in supporting the mold 300. This can not only reduce the bearing capacity of the mounting table 400 for connecting the mold 300, but also enable the mold 300 to be more stably assembled to the mounting table 400. Among them, the transport rail 500 extending in the vertical direction has good stability during the transportation of the mounting table 400, avoiding the mold 300 on the mounting table 400 from shaking during the movement of the mounting table 400.

[0126] In another alternative embodiment, the transport rail 500 extends in an arc in the vertical plane, and the transport rail 500 extending in an arc in the vertical plane can transport the mounting table 400 along an arc path, so that the movement path of the mounting table 400 is more flexible and can avoid other components on the rack.

[0127] The die-changing principle of the non-woven bag forming device will be described below in conjunction with the die-changing working process of the non-woven bag forming device 10 in this embodiment.

[0128] First, the first driving member 222 drives the clamping member 210 to move along the first guide rail 221 to the die connecting member 110, and the angle adjusting member 214 adjusts the orientation of the clamping plate 211 so that the clamping groove of the clamping plate 211 faces the die 300 to be disassembled on the die connecting member 110. Further, the die 300 to be disassembled on the die connecting member 110 is completely embedded in the clamping groove, and the control connecting member removes the die 300. The multiple limiting portions 330 of the die 300 are embedded in the corresponding limiting recesses 212, and the clamping member 210 completes the clamping of the disassembled die 300. Further, the first driving member 222 drives the clamping member 210 to move along the first guide rail 221 to the die storage area, and the second driving member 225 drives the first guide rail 221 and the clamping member 210 thereon to move along the second guide rail 223 to the corresponding position of the mounting table 400 without the connected die 300. The mounting table 400 without the connected die 300 is driven by the transport driving member 510 to move along the transport rail 500 to a position flush with the die connecting member 110 in the vertical direction. And the angle adjusting member 214 adjusts the orientation of the clamping plate 211 so that the positioning portion 320 of the die 300 in the clamping groove corresponds to the positioning recess 420 on the mounting table 400. The clamping plate 211 drives the die 300 to approach the mounting table 400 along the second direction X. The multiple positioning pin rods 322 on the die 300 are inserted into the corresponding positioning through holes 421 along the guide grooves 423. And the chuck moves downward and clamps the connecting pin head 313, and the driving cylinder drives the chuck to clamp the connecting pin head 313 to complete the die removal process.

[0129] Further, the second driving member 225 drives the first guide rail 221 and the clamping member 210 to move along the second guide rail 223 in the second direction X until they reach the corresponding position of the mounting table 400 for connecting the mold 300 to be replaced. The transportation driving member 510 drives the mounting table 400 of the replacement mold 300 to move on the transportation rail 500 until it reaches a position flush with the mold connecting member 110 in the vertical direction. Moreover, the angle adjusting member 214 adjusts the orientation of the clamping plate 211 so that the clamping groove of the clamping plate 211 corresponds to the mold 300 on the mounting table 400. Further, the clamping plate 211 moves towards the mold 300, causing the mold 300 to be inserted into the clamping groove. The driving cylinder deflates, the chuck relaxes the clamping of the locking pin, and moves upward along the vertical direction to avoid interference. The clamping member 210 clamps the mold 300 from the mounting table 400 and moves along the second direction X to a position corresponding to the mold connecting member 110. The angle adjusting member 214 adjusts the angle of the clamping plate 211 so that the mold 300 in the clamping groove faces the mold connecting member 110. The clamping member 210 moves along the first guide rail 221 towards the mold connecting member 110 until it reaches the mold connection position of the mold connecting member 110. The mold connecting member 110 connects the mold 300 through the connecting portion 310 and the positioning portion 320 on the mold 300, completing the mold installation process.

[0130] Wherein, when the length of the second guide rail 223 is equal to the width of the machine frame, when the clamping plate 211 in the mold storage area is linked by the angle adjusting member 214 to adjust the angle, for example, when the clamping plate 211 rotates towards one side of the mounting table 400, in order to prevent the clamping plate 211 from colliding with the machine frame, the second driving member 225 links the first guide rail 221 and the clamping member 210 thereon to move along the mounting table 400 on the other side, thereby providing sufficient space for the rotation of the clamping plate 211. Of course, when the width of the machine frame is sufficient, this step is not required, and the clamping plate 211 can directly adjust the angle. Those skilled in the art can design according to the actual situation and specific requirements, and this embodiment does not make specific limitations in this regard.
