Description

Technical Field

[0001] This application relates to the technical field of plastic bag production and weaving equipment, and particularly to a wire drawing processing device for plastic woven bag production. Background Art

[0002] Woven bags, also known as snake skin bags, are mainly used in the packaging industry, and their raw materials are generally chemical plastics such as polyethylene and polypropylene. They are made up of multiple flat filaments. The production of flat filaments, also known as the wire drawing process of flat filaments, mainly includes the following steps: 1. Mixing, mixing and stirring resin, filler, recycled material, masterbatch and other auxiliary materials. 2. Feeding the mixed materials into an extruder, and after extrusion by the extruder, a sheet structure (also called embryo film) is formed. 3. Slitting, the embryo film is cooled and then slit into strip-shaped embryo filaments. 4. Hot stretching, the embryo filaments are stretched after being reheated to induce the generation of an oriented micro-structure, thereby obtaining excellent mechanical properties. Finally, the embryo filaments are wound up to complete the production of flat filaments.

[0003] The wire drawing processing device for flat filaments consists of multiple modules corresponding to the above processes, which are in turn an extruder for extruding materials, a cooling water tank for cooling the embryo film, a cutting assembly for slitting the embryo film, a heating assembly for heating and stretching the embryo filaments, and a wire winding assembly for winding the embryo filaments. For example, a modified polypropylene plastic flat filament wire drawing machine disclosed in the utility model patent with the publication number CN209365311U. It mainly includes a feeding hopper, a screw feeder, a screw extruder, a die head, a cooling assembly, a tool holder, an arch plate and a winding roller arranged in sequence. The tool holder mainly includes a tool shaft and blades, and a plurality of blades are evenly spaced on the tool shaft to achieve the cutting of the embryo film into filaments.

[0004] In the actual production process, the sizes of woven belts are different, and the widths of the required flat filaments are also different. Therefore, when the width of the flat filaments to be produced changes, it is often necessary to replace the tool holder accordingly. In the related art, by rotating the tool shaft, the width of the cut flat filaments can be adjusted to a certain extent, but the width of the flat filaments that can be dealt with is relatively limited, which is not conducive to the production of current various non-standard woven bags. Summary of the Invention

[0005] In order to facilitate the production of flat filaments with different widths, this application provides a wire drawing processing device for plastic woven bag production.

[0006] The wire drawing processing device for plastic woven bag production provided by this application adopts the following technical solutions:

[0007] A wire drawing processing device for the production of plastic woven bags, comprising an extruder, a guiding roller set, a cutting assembly and a wire winding frame arranged in sequence. The cutting assembly includes a machine frame, a tool holder and a blade mounted on the machine frame. A plurality of blades are arranged on the tool holder, and the plurality of blades are spaced in a direction parallel to the width of the diaphragm to be cut. The cutting assembly further includes two mounting rods, and the two mounting rods are arranged parallel and spaced on the tool holder. The blade is located between the two mounting rods and is rotatably connected to the two blades. Rotating the mounting rod can cause the blade to displace in a direction parallel to the width of the diaphragm.

[0008] By adopting the above technical solution, the blade is connected to the two mounting rods to form a link structure of a parallelogram. On the one hand, when the mounting rod rotates, the orientation of the cutting edge of the blade does not change, improving the stability of cutting. On the other hand, when the mounting rod rotates, the distance between adjacent blades in the width of the diaphragm increases or decreases, thereby realizing stepless control of the width between the two blades, facilitating the production of flat filaments of different widths.

[0009] Optionally, the rotation axis of the mounting rod is located near the middle position of the width of the diaphragm, and the plurality of blades are divided into two groups and arranged on both sides of the rotation axis of the mounting rod respectively.

[0010] By adopting the above technical solution, when the mounting rod rotates, a plurality of blades all displace in a direction close to the rotation axis of the mounting rod, which can also be understood as the blades at both ends gathering towards the middle blade. And the rotation axis of the mounting rod corresponds to the middle position of the width of the diaphragm, thus facilitating the cutting of the diaphragm and reducing the situation that the diaphragm cannot be cut normally due to the change of the blade position.

[0011] Optionally, a driving assembly for driving the mounting rod to rotate is arranged on the tool holder. The driving assembly includes a driving plate and a driving rod. The driving plate is slidably connected to the tool holder along the width direction of the diaphragm. The driving rod is fixed on the mounting rod. A driving groove is formed on the driving plate. The driving rod is inserted into the driving groove and can slide in the driving groove. Sliding the driving plate can drive the mounting rod to rotate.

[0012] By adopting the above technical solution, one end of the driving rod is fixedly connected to the mounting rod, and the other end is slidably connected to the driving plate, realizing the connection between the mounting rod and the driving plate. The driving plate slides to drive the mounting rod to rotate. At the same time, during the cutting process, the driving plate can support and reinforce the mounting rod, reducing the situation that the mounting rod deforms under force during the cutting process and improving the stability during the use of the cutting assembly.

[0013] Optionally, two driving plates are arranged corresponding to both ends of the mounting rod. The driving assembly further includes two threaded rods corresponding to the driving plates. The threaded rods are rotatably connected to the tool holder and mesh with the driving plates.

[0014] By adopting the above technical solution, two driving plates are connected to both ends of the mounting rod, further improving the stability of the blade during the cutting process.

[0015] Optionally, a tool holder is provided between the blade and the mounting rod. The tool holder is rotatably connected to the mounting rod. A slot is provided on the tool holder, and a plug rod is provided on the blade. The plug rod is detachably inserted into the slot. A limiting member is rotatably provided in the slot, and a limiting groove is provided on the plug rod. Rotating the limiting member can cause the limiting member to be embedded in the limiting groove.

[0016] By adopting the above technical solution, the plug rod is inserted into the slot, and then the plug rod is limited by rotating the limiting member to realize the installation of the blade. Rotating the limiting member to disengage it from the limiting groove and the plug rod slides out of the slot to realize the disassembly of the blade.

[0017] Optionally, two limiting members are provided. The two limiting members are respectively provided on both sides of the blade.

[0018] By adopting the above technical solution, the two limiting members limit the blade from both sides of the blade, reducing the situation of blade inclination and improving the stability of the blade after installation.

[0019] Optionally, a linkage assembly for driving the two limiting members to rotate is provided on the tool holder. The linkage assembly includes a linkage plate. The linkage plate is slidably connected to the tool holder. A linkage gear is provided on the limiting member, and a tooth groove meshing with the linkage gear is provided on the linkage plate. Sliding the linkage plate can drive the two linkage gears to rotate synchronously.

[0020] By adopting the above technical solution, the two linkage gears are driven to rotate by the linkage plate, and then the limiting members are driven to rotate to realize the synchronous adjustment of the positions of the two limiting members, facilitating the installation and disassembly of the blade.

[0021] Optionally, a guiding member is rotatably provided on the linkage plate. A guiding groove is correspondingly provided on the tool holder. The guiding groove includes a sliding portion and a rotating portion. A sliding plane is provided on the guiding member. When the sliding plane is parallel and in contact with the side surface of the sliding portion, the guiding member can enter the sliding portion and slide along with the linkage plate.

[0022] By adopting the above technical solution, when it is necessary to slide the linkage plate, the guiding member is rotated so that the sliding plane corresponds to the sliding portion. In this state, the guiding member can move along with the linkage plate. When it is not necessary to slide the linkage plate, the guiding member can limit the linkage plate by rotation, thereby improving the stability of the limiting member in limiting the plug rod.

[0023] Optionally, an elastic sensitive element is provided on the tool holder, the blade abuts against the elastic sensitive element and can move in a direction close to the elastic sensitive element, and the elastic sensitive element can detect the magnitude of the force exerted on itself by the blade.

[0024] By adopting the above technical solution, the force on the blade is detected by the elastic sensitive element, so that the sharpness of the blade can be judged, which is convenient for the staff to replace the blade in time.

[0025] Optionally, a rotating plate is provided between the mounting rod and the tool holder, a rotating disc is rotatably provided on the rotating plate, the rotation axis of the rotating disc is perpendicular to the rotation axis of the rotating plate, and a plurality of blades are uniformly spaced around the rotation axis of the rotating disc.

[0026] By adopting the above technical solution, the rotating plate is provided to facilitate the connection between the tool holder and the mounting rod. Rotating the rotating disc can exchange the positions of multiple blades, so that it is convenient for the staff to quickly replace the blades and improve the production efficiency of the flat wire drawing process.

Detailed implementation manners

[0039] The following further Figure 1-11 describes the present application in detail with reference to the

[0040] The embodiment of the present application discloses a wire drawing processing device for producing plastic woven bags.

[0041] Referring to Figure 1 and Figure 2 , a wire drawing processing device for producing plastic woven bags includes a flat die extruder 11, a guiding roller group 12, a cutting component 13, and a wire take-up frame 14 for winding flat filaments, which are arranged in sequence. The flat die extruder 11 is used to extrude a sheet-like film, and the guiding roller group 12 is used to guide the film to move towards the wire take-up frame 14. The cutting component 13 is used to cut the film, and the wire take-up frame 14 drives the flat filaments towards the wire take-up frame 14, and the film moves accordingly. When the film moves, the cutting component 13 moves relative to the film, so that the cutting component 13 can divide the film.

[0042] Referring to Figure 3 and Figure 4, the cutting assembly 13 includes a frame 131, a tool rest 132 and a plurality of blades 133 mounted on the frame 131. The plurality of blades 133 are spaced apart in the width direction of the diaphragm. The blades 133 are perpendicular to the ground and parallel to the length direction of the diaphragm, and the cutting edges face the extruder 11, so that the diaphragm can be longitudinally cut to facilitate dividing the diaphragm into multiple flat filaments. The blades 133 can move in the width direction of the diaphragm, so that the distance between adjacent blades 133 can be adjusted, and thus the width of the flat filaments formed by cutting can be adjusted. Moreover, according to the moving distance of the blades 133, theoretically, flat filaments of countless widths can be cut, broadening the applicable range of the cutting assembly 13 and facilitating the production of flat filaments of various widths in the manufacturer's production.

[0043] Refer to Figure 2 and Figure 3 , the cutting assembly 13 further includes two mounting rods 134, and the two mounting rods 134 are arranged in parallel at intervals along the width direction of the diaphragm. Combining Figure 4 , the mounting rod 134 is rotatably connected to the tool rest 132 around a vertical axis. The blade 133 is located between the two mounting rods 134 and is rotatably connected to the two mounting rods 134 to form a parallelogram linkage mechanism. During the rotation of the mounting rod 134, the blade 133 can be driven to generate displacement in the width direction of the diaphragm, so as to realize the adjustment of the distance between the blades 133. Moreover, since a plurality of blades 133 are all connected to the mounting rod 134, it is convenient to synchronously adjust the distance between the plurality of blades 133 and quickly realize the adjustment of the distance between the blades 133.

[0044] Refer to Figure 2 and Figure 3 , a plane perpendicular to the width direction of the diaphragm and located at the middle position of the width of the diaphragm is defined as the middle plane. The rotation axes between the two mounting rods 134 and the tool rest 132 are symmetric about the middle plane. The middle position in the length direction of the mounting rod 134 is rotatably connected to the tool rest 132. Combining Figure 4 , the plurality of blades 133 are divided into two groups and are respectively arranged on both sides of the rotation axis of the mounting rod 134. After the extruder 11 extrudes the diaphragm, the position of the diaphragm is relatively fixed. Through the above settings, when the mounting rod 134 rotates, the blades 133 gather towards the middle plane to facilitate cutting the diaphragm.

[0045] Refer to Figure 3 and Figure 4 , the cutting assembly 13 further includes a rotating plate 135 corresponding to the blade 133. The rotating plate 135 is arranged between the two mounting rods 134, and both sides of the rotating plate 135 are rotatably connected to the two mounting rods 134 respectively. The blade 133 is mounted on the rotating plate 135 to realize the rotational connection between the blade 133 and the mounting rod 134, which is convenient for the installation of the blade 133.

[0046] Reference Figure 2 and Figure 3 , a drive assembly 2 for driving the mounting rod 134 to rotate is provided on the tool rest 132. Combining Figure 4 , the drive assembly 2 includes a drive plate 21 and a drive rod 22. The drive plate 21 is slidably connected to the tool rest 132 in a direction parallel to the width of the diaphragm. The drive rods 22 are provided in two numbers, and the two drive rods 22 are respectively fixedly welded to the two mounting rods 134. The drive rod 22 is of a cylindrical structure. A plane where the rotation axis between the plurality of rotating plates 135 and the mounting rod 134 is located is defined as a coexistence plane. The axis of the drive rod 22 coincides with the coexistence plane. The drive plate 21 is slidably engaged with the tool rest 132 in the direction of the width of the diaphragm, and the drive plate 21 is located above the mounting rod 134. A drive groove 23 is provided on the side of the drive plate 21 close to the ground corresponding to the drive rod 22. The drive groove 23 is a kidney-shaped groove, and the length direction of the kidney-shaped groove is horizontal and perpendicular to the width direction of the diaphragm. One end of the drive rod 22 facing away from the ground is inserted into the drive groove 23. The drive rod 22 can rotate relative to the drive plate 21 around its own axis in the drive groove 23 and can slide along the length direction of the drive groove 23. By sliding the drive plate 21, the mounting rod 134 can be driven to rotate, realizing the drive of the rotation of the mounting rod 134. At the same time, under the action of the drive rod 22 and the drive plate 21, the support of the end of the mounting rod 134 is realized, which can improve the stability of the blade 133 during the cutting process and improve the cutting effect.

[0047] Reference Figure 2 and Figure 3 , the drive assembly 2 further includes two threaded rods 24 provided corresponding to the drive plate 21. The threaded rods 24 are rotatably connected to the tool rest 132. The two threaded rods 24 are coaxially arranged and rotatably connected to the tool rest 132. The threaded rods 24 are threadedly connected to the drive plate 21. Rotating the threaded rods 24 can drive the drive plate 21 to move. A drive member 25 for driving the two threaded rods 24 to move is provided between the two drive plates 21. The drive member 25 is located at the middle position of the tool rest 132 in the width direction of the diaphragm. In this embodiment, the drive member 25 is a double-shaft motor (57BH2A76-304). The housing of the double-shaft motor is fixedly connected to the tool rest 132. The two output shafts of the double-shaft motor are respectively coaxially fixedly connected to the two threaded rods 24, thereby realizing the synchronous rotation of the two threaded rods 24. The thread directions on the threaded rods 24 are opposite to facilitate driving the two drive plates 21 to approach or move away from each other synchronously.

[0048] Reference Figure 5 and Figure 6 , a tool fixing assembly 3 is provided between the rotating plate 135 and the blade 133. The tool fixing assembly 3 includes a tool holder 31. A slot 32 is provided on the side of the tool holder 31 close to the ground. A plug rod 33 is provided on the blade 133. The plug rod 33 is inserted into the slot 32 to realize the detachable connection between the blade 133 and the tool holder 31.

[0049] Referring to Figure 7 and Figure 8 Figure 8 , the tool fixing assembly 3 further includes a limiting member 34, and the limiting member 34 is of a sector structure. A rotating groove 35 is formed in the side wall of the slot 32. The limiting member 34 is rotatably connected in the rotating groove 35 around its own axis, and the axis of the limiting member 34 is perpendicular to the opening direction of the slot 32. A limiting groove 36 is formed in the insert rod 33 at a position corresponding to the limiting member 34. The limiting groove 36 is an arc-shaped groove coaxial with the limiting member 34. The arc-shaped surface of the limiting member 34 is embedded in the limiting groove 36, so as to limit the insert rod 33 and realize the fixing of the blade 133. By rotating the limiting member 34, the limiting member 34 can be immersed in the rotating groove 35, so that it is separated from the limiting groove 36, facilitating the disassembly of the blade 133 and realizing the detachable connection between the blade 133 and the tool holder 31.

[0050] Referring to Figure 7 and Figure 8 Figure 8 , in order to improve the stability of the blade 133 after being installed on the tool holder 31, two limiting members 34 are provided. The two limiting members 34 are respectively arranged on both sides of the blade 133 along the thickness direction of the blade 133, so as to limit the insert rod 33 from different positions.

[0051] Referring to Figure 5 and Figure 6 Figure 6 , a linkage assembly 4 for driving the limiting member 34 to rotate is arranged on the tool holder 31. The linkage assembly 4 includes a linkage plate 41. The linkage plate 41 is slidably connected to the tool holder 31 along a direction perpendicular to the rotation axis of the limiting member 34, and the linkage plate 41 is located between the two limiting members 34. A linkage gear 42 is arranged at one end of the limiting member 34 close to the linkage plate 41. A tooth groove meshing with the linkage gear 42 is formed on the side wall of the linkage plate 41 corresponding to the linkage gear 42. Sliding the linkage plate 41 can drive the two linkage gears 42 to rotate, and further drive the two limiting members 34 to rotate synchronously, facilitating the installation and disassembly of the blade 133.

[0052] Referring to Figure 5 and Figure 9, the linkage component 4 further includes a guide member 43, which is integrally in a block structure. There are two mutually parallel sliding planes 431 and two coaxial and equal-radius arc surfaces 432 provided on the guide member 43. The guide member 43 is rotatably connected to the side of the linkage plate 41 close to the tool holder 31 around the axis of the arc surface 432. A guide groove 45 is formed in the tool holder 31, and the guide member 43 is located in the guide groove 45. The guide groove 45 includes a sliding portion 451 and a rotating portion 452. The sliding portion 451 is a rectangular groove with a length direction parallel to the sliding direction of the linkage plate 41, and the rotating portion 452 is a circular groove with a radius equal to that of the arc surface 432. The rotating portion 452 communicates with the sliding portion 451. When the two sliding planes 431 are parallel to the length direction of the sliding portion 451, the guide member 43 can enter the sliding portion 451, and the sliding planes 431 are attached to the two side surfaces of the sliding portion 451, thereby guiding the sliding of the linkage plate 41. When the guide member 43 enters the rotating portion 452 and the guide member 43 is rotated, the sliding planes 431 can be arranged at an angle with the sliding portion 451, thereby blocking the guide member 43 from entering the sliding portion 451 to limit the sliding of the linkage plate 41, and further limiting the rotation of the limiting member 34, improving the stability of the limiting member 34 in limiting the plug rod 33.

[0053] Referring to Figure 5 and Figure 9 , a knob 44 is arranged on the side of the linkage plate 41 away from the guide member 43. The knob 44 is rotatably connected to the linkage plate 41 and fixedly connected to the guide member 43. On the one hand, it is convenient for the staff to rotate the guide member 43, and on the other hand, it is convenient to slide the linkage plate 41.

[0054] Referring to Figure 5 and Figure 6, an elastic sensitive element 5 (which can also be understood as a gravity sensor or a displacement sensor) is further provided on the tool holder 31. The elastic sensitive element 5 is integrally in a rectangular rod shape and is arranged parallel to the inserting rod 33. And one end of it is fixed on the tool holder 31. A contact member 51 is provided on the blade 133, and the contact member 51 is located between the elastic sensitive element 5 and the inserting rod 33. The limiting groove 36 on the inserting rod 33 penetrates along the direction parallel to the axis of the limiting member 34, so that the inserting rod 33 can slide along the direction parallel to the axis of the limiting member 34. The side wall of the slot 32 close to the elastic sensitive element 5 is spaced from the inserting rod 33, so that the inserting rod 33 can move in the direction close to the elastic sensitive element 5. During the diaphragm cutting process, the blade 133 is subjected to the reaction force of the diaphragm and has a tendency to move in the direction close to the elastic sensitive element 5. Under the action of the contact member 51, the elastic sensitive element 5 is bent, and then the magnitude of the reaction force received by the blade 133 is detected through the piezoelectric effect (for a non-centrosymmetric heteropolar crystal, the external force applied to the crystal will not only cause the crystal to deform, but also change the polarization state of the crystal and establish an electric field inside the crystal. This phenomenon of polarization of the medium due to the action of mechanical force). According to the magnitude of the reaction force received by the blade 133, the sharpness of the blade 133 can be judged, so as to facilitate the staff to replace the blade 133 in time.

[0055] Refer to Figure 5 and Figure 6 , the contact member 51 includes a connecting plate 511 and a contact ball 512. One side of the connecting plate 511 is welded to the blade 133, and the other side extends between the elastic sensitive element 5 and the inserting rod 33. The contact ball 512 is in a hemispherical structure and is arranged between the connecting plate 511 and the elastic sensitive element 5. The spherical surface of the contact ball 512 is in contact with the elastic sensitive element 5. By using the spherical surface, the elastic sensitive element 5 can stably contact with the blade 133 during the deformation process, which is convenient for detecting the force condition of the blade 133.

[0056] Refer to Figure 5 and Figure 6 , under normal conditions, the side wall of the inserting rod 33 away from the elastic sensitive element 5 is in contact with the side wall of the slot 32 away from the elastic sensitive element 5. Under the action of the elastic sensitive element 5 and the slot 32, the movement of the inserting rod 33 can be limited, so as to reduce the situation of the blade 133 shaking during use.

[0057] Refer to Figure 10 and Figure 11, a rotating disk 8 is provided on the rotating plate 135, and the rotating disk 8 has a disk-shaped structure. A fixed rod 81 is provided below the rotating plate 135, and the rotating disk is rotatably connected to the fixed rod 81 about its own axis. The rotation axis of the rotating disk 8 is parallel to the width direction of the diaphragm, and the tool holder 31 is installed on the rotating disk 8. And at least three tool holders 31 are evenly spaced along the axis direction of the rotating disk 8, and four are provided in this embodiment. At the same time, a plurality of blades 133, insertion rods 33, and elastic sensitive elements 5 are correspondingly provided. Rotating the rotating disk 8 can quickly move the adjacent blades 133 to the positions corresponding to the diaphragm. Moreover, during the diaphragm cutting process, by rotating the rotating disk 8, before the blade 133 is separated from the diaphragm, the adjacent blades 133 can move to the positions for cutting the diaphragm, so that the process of replacing the blade 133 does not require shutdown, improving the overall efficiency of the flat wire drawing process.

[0058] Refer to Figure 10 and Figure 11 , a one-way limiting component 6 is provided at the position of the rotating plate 135 corresponding to the rotating disk 8. The one-way limiting component 6 includes a clamping rod 61. The clamping rod 61 is slidably connected to the rotating disk 8 along the direction parallel to the rotation axis of the rotating disk 8. A clamping groove 62 is opened at the position of the fixed rod 81 corresponding to the clamping rod 61. The clamping rod 61 can be inserted into the clamping groove 62 at one end by sliding the clamping rod 61, thereby limiting the rotation of the rotating disk 8 and improving the stability during the cutting process of the blade 133.

[0059] Refer to Figure 10 and Figure 11 , the blade 133 located below is defined as the in-use blade, and the other blades 133 are defined as spare blades. Combining Figure 1 , the rotation in the direction of making the in-use blade close to the extruder 11 is defined as the forward rotation. An extraction inclined surface 63 is provided on one side wall of the clamping groove 62. When the rotating disk 8 rotates forward, the extraction inclined surface 63 abuts against the clamping rod 61, and the clamping rod 61 can be automatically guided to disengage from the clamping groove 62 under the action of the extraction inclined surface 63, canceling the limit on the rotation of the rotating disk 8 and enabling the rotating disk 8 to rotate freely forward. When the rotating disk 8 rotates reversely, it is blocked by the clamping rod 61, so that the reverse rotation of the rotating disk 8 can be blocked, realizing the one-way rotation of the rotating disk 8. The one-way limiting component 6 further includes an elastic member for applying a force to the clamping rod 61 to make it move in the direction close to the clamping groove 62. In this embodiment, the elastic member is a spring, one end of the spring is connected to the clamping rod, and the other end is connected to the rotating disk.

[0060] Refer to Figure 1 and Figure 3, a lifting member 7 for driving the tool rest 132 to lift is provided on the frame 131. At the beginning of flat wire production, the end of the diaphragm moves from the side close to the extruder 11 towards the take-up reel 14. At this time, the cutting assembly 13 is located above the diaphragm. After the end of the diaphragm moves to the side of the cutting assembly 13 away from the extruder 11, the cutting assembly 13 is driven to move down by the lifting member 7, so that the cutting edge can divide the diaphragm, facilitating the smooth progress of the process. In this embodiment, the lifting member 7 is an oil cylinder. One end of the oil cylinder is fixed on the frame 131, and the other end is fixed to the tool rest 132.
