Description

Technical Field

[0001] This invention relates to the field of plastic conveying technology, specifically to fully automatic plastic woven bag forming equipment. Background Technology

[0002] Plastic woven bags are widely used as packaging materials for fertilizers, chemical products, and other items. Their main production process involves extruding plastic raw materials into film, cutting, and unidirectionally stretching them into flat filaments, which are then woven together to produce the final product, commonly known as a woven bag.

[0003] When producing and shaping plastic woven bags, it is necessary to transport and cut the formed plastic woven bags. In the process of transporting plastic woven bags, special transport and forming equipment is required.

[0004] However, this conveying and forming equipment has the following drawbacks in practical use: Existing conveying and forming equipment typically uses a zigzag conveyor system to directionally transport woven plastic bags during production, ensuring their stability during subsequent cutting and blow molding processes. This system utilizes multiple bends in the conveyor to maintain stability during feeding. However, during this transport, especially towards the side of the cutting or blow molding structure, the bags need to be horizontal to facilitate positioning during these operations. However, horizontally conveyed bags are prone to bulging or bending along this section, leading to problems such as bending, misalignment during cutting and blow molding, and a higher number of substandard, low-quality woven bags after cutting. In the directional conveying of woven plastic bags, several guide wheels, conveyor rollers, and auxiliary structures are required to ensure stability and automate the conveying process. However, with traditional guide wheels, conveyor rollers, and auxiliary structures, impurities on the surface of the woven plastic bags tend to adhere and adhere to the surface during auxiliary conveying. During subsequent compression and positioning, the conveying woven bags are prone to friction with these adhered impurities, leading to scratches or even breakage on the surface and affecting the normal conveying of the bags. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic plastic woven bag forming equipment to solve the problems mentioned in the background art.

The servo feeding roller is movably disposed on the side of the central conveying wheel. The intermediate conveyor wheel is equipped with a forward and reverse positioning assembly on one side of its top.

[0010] As a preferred embodiment of the present invention, the positioning and conveying assembly includes: a second drive source installed on one side of the side support plate; a linear conveying wheel connected to the output end of the second drive source and movably connected inside the side support plate; and a transmission belt connected to the outside of the linear conveying wheel and movably connected to the outside of the side support plate via a synchronous pulley. One of the linear conveyor wheels has a half gear mounted on its bottom, and a surface cleaning component is mounted on the outer side of the bottom of the other linear conveyor wheel.

[0011] As a preferred embodiment of the present invention, two linear conveying wheels are provided, both of which are located on the same side of the intermediate conveying wheel, and a guide wheel rotatably connected to the top of the side support plate is provided on the top of the linear conveying wheel.

[0012] As a preferred embodiment of the present invention, the forward and reverse positioning assembly includes: a toothed rod mounted on one side of the top of the toothed frame; a rotating gear meshing with the top of the toothed rod and movably connected to the side of the side support plate; a rotating rod connected to the rotating gear and movably disposed on the inner side of the side support plate; an L-shaped connecting rod mounted on the outer side of the rotating rod; and a positioning roller rotatably connected to the L-shaped connecting rod. The L-shaped connecting rod and positioning roller are provided in multiple ways, and the top of the positioning roller abuts against the surface cleaning component.

[0013] As a preferred embodiment of the present invention, the surface cleaning assembly includes: a side conveyor belt connected to the outer side of the bottom of the linear conveyor wheel via a synchronous pulley, the side conveyor belt being movably disposed on the side of the toothed frame; a horizontal lead screw connected to the inner side of the side conveyor belt via a synchronous pulley and rotatably connected to the interior of an upper bracket, the upper bracket being mounted on the top of a side support plate; a horizontal slider connected to the outer side of the horizontal lead screw via ball bearings; a horizontal rod mounted inside the upper bracket; a side guide rod connected to the horizontal slider and slidably connected to the outer side of the horizontal rod; and a horizontal assembly cylinder mounted outside the side guide rod and movably connected to the outer side of the horizontal rod.

[0014] As a preferred embodiment of the present invention, an assembly groove is provided at the bottom of the horizontal assembly cylinder, and a cleaning brush located inside the assembly groove is installed on the horizontal assembly cylinder by screws. The cleaning brush is positioned above the intermediate conveyor wheel.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In fully automatic plastic woven bag forming equipment, when cutting and blowing the shaped plastic woven bags, the second drive source can be activated to continuously rotate the linear conveyor wheel at the bottom of the plastic woven bag. This causes the plastic woven bag, which is pressed against the top of the linear conveyor wheel, to move horizontally, facilitating its movement into the cutting equipment. Simultaneously, the rotation of the linear conveyor wheel also drives the half-gear to rotate, causing the toothed frame connected to the half-gear to reciprocate horizontally. Through the gear meshing design, this drives the L-shaped connecting rod and positioning roller to rotate 90 degrees longitudinally. When the L-shaped connecting rod and positioning roller are horizontal, they press down and fix the bottom of the plastic woven bag, ensuring that the tail of the plastic woven bag is initially compressed and fixed during cutting, preventing deviation and shaking. When the L-shaped connecting rod and the positioning roller are in a vertical position, the positioning roller is located at the bottom of the cleaning brush. The longitudinal movement (reciprocating motion) of the cleaning brush automatically cleans the surface of the positioning roller, reducing the problem of impurities adhering to the surface of the plastic woven bag and causing scratches, thus enhancing safety. 2. In fully automatic plastic woven bag forming equipment, the linear conveyor wheel that rotates to transport the plastic woven bags can also drive the horizontal assembly cylinder and cleaning brush to reciprocate (in the longitudinal direction) on the outside of the horizontal rod via belt and screw drive. The reciprocating movement of the cleaning brush in the longitudinal direction automatically cleans the surface of the positioning rollers that intermittently rotate to the bottom of the cleaning brush, automatically removing debris adhering to the surface of the positioning rollers during the pressing and fixing of the plastic woven bags (plastic operation). Simultaneously, due to the certain activity time during the switching between vertical and horizontal states of the L-shaped connecting rod and the positioning rollers, this time is the time for feeding the plastic woven bags. The three components work together to achieve automated and highly efficient plastic woven bag conveying and cutting operations. 3. In fully automatic plastic woven bag forming equipment, during the conveying and subsequent cutting of plastic woven bags, a conveying path (with a bent structure) composed of multiple upper and lower conveyor rollers ensures that the plastic woven bags can pass through multiple bends during conveying. This increases the friction intensity between the plastic woven bags and the conveyor rollers, reducing the probability of the plastic woven bags shifting or loosening during conveying. Simultaneously, the bent conveying channel design minimizes the space required for conveying the plastic woven bags, easily adapting to various conveying lines and facilitating optimized production line layout within limited space. 4. In fully automatic plastic woven bag forming equipment, the combined and connected bending plastic woven bag conveying channels and horizontal plastic woven bag conveying channels can make more efficient use of workshop space, adapt to complex production line layouts, and achieve a compact plastic woven bag production process. Simultaneously, the horizontal conveying of plastic woven bags can compensate for the bending channel conveying, reducing vibration and tension fluctuations when the plastic woven bags turn within the bending channel, improving conveying stability and accuracy, and reducing the likelihood of tearing the plastic woven bags.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] Example 1 Please see Figures 1-11The fully automatic plastic woven bag forming equipment includes a bottom frame 10; a plastic folding conveyor structure 20 installed on one side of the top of the bottom frame 10; a side support plate 30 installed on the other side of the top of the bottom frame 10; and a plastic positioning and feeding structure 40 installed inside the side support plate 30 and extending to the top of the side support plate 30. The plastic positioning and feeding structure 40 includes: a positioning conveyor assembly 401 installed on the side of the side support plate 30 and extending to the inside of the side support plate 30; a half gear 402 installed at the bottom of the positioning conveyor assembly 401 and movably disposed on the outside of the side support plate 30; a toothed frame 403 meshing with the outside of the half gear 402 and movably connected to the outside of the side support plate 30; a forward and reverse positioning assembly 404 meshing with the toothed frame 403 and disposed on the side of the positioning conveyor assembly 401; and a surface cleaning assembly 405 connected to the positioning conveyor assembly 401 and installed on the top of the side support plate 30. The surface cleaning assembly 405 is disposed above the forward and reverse positioning assembly 404, and teeth are provided on both the upper and lower sides of the inner wall of the toothed frame 403.

[0021] In this scheme, an intermediate conveyor wheel 300 is movably connected to the top center of the side support plate 30, a servo drive source 301 is installed on the outside of the side support plate 30, the output end of the servo drive source 301 is connected to a servo feeding roller 302 movably connected inside the side support plate 30, the servo feeding roller 302 is movably arranged on the side of the intermediate conveyor wheel 300, and a forward and reverse positioning component 404 is installed on one side of the top of the intermediate conveyor wheel 300.

[0022] The working principle described above is as follows: When producing and shaping plastic woven bags, the pre-shaped plastic woven bags need to be cut and blown into shape. To ensure accuracy and efficiency during cutting and blowing, specialized conveying equipment is required. The plastic woven bags are first conveyed to one side of the positioning conveying component 401 via a plastic zigzag conveyor structure 20. The zigzag conveyor structure 20 creates a zigzag conveying trajectory, ensuring that the plastic woven bags are not prone to bending or loosening during conveying. Upon entering the positioning conveying component 401, the plastic woven bags are first changed from a bent state to a horizontal conveying state, ensuring that the plastic woven bags are horizontal when entering the cutting equipment. During the horizontal conveying of the plastic woven bags, the operation of the positioning conveying component 401 can drive the half gear 402 installed on its outer side to rotate continuously. At this time, through the intermittent meshing transmission between the half gear 402 and the teeth on both sides of the toothed frame 403, the toothed frame 403 can be continuously driven to move back and forth in the horizontal direction, which drives the forward and reverse positioning component 404 connected to the toothed frame 403 to operate. After the plastic woven bags have been conveyed for a certain distance (the length of the plastic woven bags to be cut), the bottom position of the plastic woven bags in the conveying state is pressed down and fixed to ensure that the plastic woven bags in the cutting state are not prone to deviation and shaking, which facilitates the high-precision plastic woven bag cutting operation.

[0023] It should be noted that when the positioning and conveying component 401 is in operation, it can also drive the surface cleaning component 405 to operate, automatically cleaning the surface of the forward and reverse positioning component 404 that has rotated to the bottom of the surface cleaning component 405. This reduces the amount of impurities on the surface of the plastic woven bag adsorbed on the surface of the forward and reverse positioning component 404, and reduces the probability of scratches or even cracks on the surface of the plastic woven bag when it is continuously pressed down and positioned, thereby improving the quality of the plastic woven bag after processing.

[0024] Furthermore, by using the servo drive source 301 to drive the servo feed roller 302 to rotate, the top of the plastic woven bag can be moved, and with the handle structure set on its side, the plastic woven bag can be horizontally entered into the cutting equipment.

[0025] For details, please refer to the following: Figure 4 and Figure 5The plastic zigzag conveyor structure 20 includes: a first drive source 201 installed on one side of the top of the bottom frame 10; an upper conveyor wheel 202 connected to the output end of the first drive source 201 and movably disposed inside the bottom frame 10; an inclined belt 203 connected to the bottom of the upper conveyor wheel 202 via a synchronous pulley; and a lower conveyor wheel 204 connected to the inside of the inclined belt 203 via a synchronous pulley and movably connected inside the bottom frame 10. There are two lower conveyor wheels 204, which are disposed at the bottom of the upper conveyor wheel 202 and connected to each other via a lower synchronous belt 2041.

[0026] In this scheme, there are four upper conveyor wheels 202. Two adjacent upper conveyor wheels 202 are connected by an upper synchronous belt 2021. There are multiple upper synchronous belts 2021, which are arranged sequentially to each other.

[0027] In the fully automatic plastic woven bag forming equipment of the present invention, when cutting the plastic woven bags, the plastic woven bags are first placed on the outside of multiple upper conveyor rollers 202 and lower conveyor rollers 204, forming a bent conveying channel on the outside of the upper conveyor rollers 202 and lower conveyor rollers 204. This bent conveying channel ensures that the plastic woven bags are less prone to bending or loosening during transport. When conveying the plastic woven bags, the first drive source 201 is activated, causing the upper conveyor rollers 202 connected to the output end of the first drive source 201 to rotate. Multiple upper synchronous belts 2021 connected to the upper conveyor rollers 202 drive the upper conveyor rollers 202 to rotate synchronously. Furthermore, the rotation of the upper conveyor rollers 202 also drives the lower conveyor rollers 204 connected to their bottoms via synchronous pulleys to rotate, ensuring that the lower conveyor rollers 204 and upper conveyor rollers 202 rotate synchronously and in the same direction, achieving stable and automatic plastic woven bag feeding.

[0028] For details, please refer to the following: Figure 7 and Figure 8 The forward and reverse positioning assembly 404 includes: a second drive source 4011 installed on one side of the side support plate 30; a linear conveyor wheel 4012 connected to the output end of the second drive source 4011 and movably connected inside the side support plate 30; and a transmission belt 4013 connected to the outside of the linear conveyor wheel 4012 and movably connected to the outside of the side support plate 30 via a synchronous pulley. A half gear 402 is installed at the bottom of one of the linear conveyor wheels 4012, and a surface cleaning assembly 405 is installed on the outside of the bottom of the linear conveyor wheel 4012.

[0029] In this scheme, there are two linear conveyor wheels 4012, both of which are located on the same side of the middle conveyor wheel 300. The top of the linear conveyor wheel 4012 is provided with a guide wheel 40121 that is rotatably connected to the top of the side support plate 30.

[0030] In the fully automatic plastic woven bag forming equipment of the present invention, when the plastic woven bag is conveyed horizontally to ensure the stability of subsequent cutting operations, the second drive source 4011 is activated, operating in unison with the first drive source 201. The operation of the second drive source 4011 drives the linear conveyor wheel 4012 connected to its output end to horizontally convey the plastic woven bag that is contacting the top of the linear conveyor wheel 4012. The design of the transmission belt 4013 on the outer side of the linear conveyor wheel 4012 ensures that the two linear conveyor wheels 4012 rotate synchronously and in the same direction.

[0031] It should be noted that by setting guide wheels 40121 on the top of the two rotating linear conveyor wheels 4012, the top of the plastic woven bag can be pressed down during the conveying process. The pressure unit set on the outer surface of the guide wheels 40121 can provide timely tension compensation when the plastic woven bag bulges or bends (by changing the rotation speed of the second drive source 4011).

[0032] Furthermore, when the linear conveyor wheel 4012 rotates, the half gear 402 installed at its bottom will rotate continuously, driving the outer meshing connecting tooth frame 403 of the half gear 402 to reciprocate horizontally.

[0033] For details, please refer to the following: Figure 10 and Figure 11 The forward and reverse positioning assembly 404 includes: a toothed bar 4041 mounted on one side of the top of the toothed frame 403; a rotating gear 4042 meshing with the top of the toothed bar 4041 and movably connected to the side of the side support plate 30; a rotating rod 4043 connected to the rotating gear 4042 and movably disposed inside the side support plate 30; an L-shaped connecting rod 4044 mounted on the outside of the rotating rod 4043; and a positioning roller 4045 rotatably connected to the L-shaped connecting rod 4044. Multiple L-shaped connecting rods 4044 and positioning rollers 4045 are provided, and the top of the positioning rollers 4045 abuts against a surface cleaning assembly 405.

[0034] In the fully automatic plastic woven bag forming equipment of the present invention, when the toothed frame 403 reciprocates horizontally, the toothed rod 4041 mounted on its top operates synchronously, driving the rotating gear 4042 meshing with the top of the toothed rod 4041 to rotate (continuously forward and reverse). When the rotating gear 4042 rotates forward and reverse, the L-shaped connecting rod 4044 connected to its side rotates, driving the positioning roller 4045 mounted on the outer side of the L-shaped connecting rod 4044 to rotate longitudinally (90 degrees).

[0035] It should be noted that when the L-shaped connecting rod 4044 and the positioning roller 4045 are in a horizontal state, the plastic woven bag at the bottom of the positioning roller 4045 is pressed down and fixed; when the L-shaped connecting rod 4044 and the positioning roller 4045 are in a vertical state, the surface cleaning component 405 can clean the surface of the positioning roller 4045.

[0036] For details, please refer to the following: Figure 9 and Figure 11 The surface cleaning assembly 405 includes: a side conveyor belt 4051 connected to the outer side of the bottom of the linear conveyor wheel 4012 via a synchronous pulley, the side conveyor belt 4051 being movably disposed on the side of the toothed frame 403; a horizontal lead screw 4053 connected to the inner side of the side conveyor belt 4051 via a synchronous pulley and rotatably connected to the interior of the upper bracket 4052, the upper bracket 4052 being mounted on the top of the side support plate 30; a horizontal slider 4054 connected to the outer side of the horizontal lead screw 4053 via ball bearings; a horizontal rod 4055 mounted on the inner side of the upper bracket 4052; a side guide rod 4056 connected to the horizontal slider 4054 and slidably connected to the outer side of the horizontal rod 4055; and a horizontal assembly cylinder 4057 mounted on the outer side of the side guide rod 4056 and movably connected to the outer side of the horizontal rod 4055, wherein multiple horizontal rods 4055 are installed, and the length of the horizontal assembly cylinder 4057 is less than the length of the horizontal rod 4055.

[0037] In this design, the bottom of the horizontal assembly cylinder 4057 is provided with an assembly groove 40571. The horizontal assembly cylinder 4057 is fitted with a cleaning brush 40572 located inside the assembly groove 40571 by screws. The cleaning brush 40572 is positioned above the intermediate conveyor wheel 300.

[0038] In the fully automatic plastic woven bag forming equipment of the present invention, when the linear conveyor wheel 4012 rotates continuously (unidirectionally), the side conveyor belt 4051 connected to its outer side via a synchronous pulley operates, causing the horizontal lead screw 4053 connected to the inner side of the side conveyor belt 4051 via the synchronous pulley to rotate. When the horizontal lead screw 4053 rotates, the horizontal slider 4054 connected to its outer side via ball bearings reciprocates (in the longitudinal direction) outside the horizontal lead screw 4053, driving the side guide rod 4056 and the horizontal assembly cylinder 4057 mounted on the side of the horizontal slider 4054 to operate (in the longitudinal direction).

[0039] When the horizontal assembly cylinder 4057 operates (in the longitudinal direction), it moves outside the horizontal rod 4055, which guides its movement. The bottom of the horizontal assembly cylinder 4057 can continuously reciprocate (in the longitudinal direction) via the cleaning brush 40572 on the assembly groove 40571, cleaning the surface of the positioning roller 4045 located at the bottom of the cleaning brush 40572.

[0040] Example 2 For details, please refer to the following: Figure 12 A connecting seat 50 is installed on the inner side of the side support plate 30 by screws. The connecting seat 50 is located on the outer side of the servo feed roller 302. A pressing guide rod 501 is rotatably connected to the side of the connecting seat 50. The pressing guide rod 501 is located on the left and right sides of the top of the servo feed roller 302.

[0041] A feeding rack 101 is installed on one side of the bottom frame 10, and multiple bottom rollers 102 are rotatably connected to the inner bottom of the feeding rack 101.

[0042] In the fully automatic plastic woven bag forming equipment of the present invention, by setting a pressure guide rod 501 on the outer side of the top of the servo feeding roller 302, the plastic woven bag transmitted to the bottom side of the pressure guide rod 501 can be pressure-guided, ensuring that the plastic woven bag is not prone to bulging or loosening when it is conveyed to the inside of the cutting equipment for cutting.

[0043] By installing a feed rack 101 on one side of the feed inlet of the bottom frame 10, the plastic woven bag conveyed on top of the bottom rollers 102 can be supported and guided by several bottom rollers 102 that are movably arranged inside, so as to ensure that the plastic woven bag can smoothly enter the side of the plastic zigzag conveyor structure 20.
