Description

Technical Field

[0001] This application relates to the technical field of ton bag processing equipment, and in particular to a feeding device for ton bag processing. Background Technology

[0002] In the production and processing of ton bags, the raw material fabric used is usually stored and supplied in roll form. The common feeding method is to install the rolled fabric on the equipment support frame, pull the fabric off the roll by direct dragging, and fix its front end on the traction machine of the subsequent process to unfold it into a continuous fabric sheet.

[0003] However, this traditional feeding method has the following problems: Firstly, the dragging and pulling method can easily cause mechanical damage to the fabric sheet, potentially leading to tearing or deformation during the pulling process, directly affecting the quality and yield of the final product. Secondly, due to production process requirements, the fabric sheet feeding process is intermittent. This discontinuous dragging causes the roll to develop rotational inertia, resulting in continuous fluctuations in fabric tension. This instability in tension further affects the processing accuracy of subsequent processes, especially in sewing and cutting stages that require precise positioning, easily leading to product dimensional deviations and affecting the consistency of production quality.

[0004] In addition, rolls of fabric are usually coated with a protective powder layer. During production, this powder is dispersed in large quantities as the fabric sheets move, forming industrial dust. This dust suspended in the air not only pollutes the workshop environment but also affects the health of the operators. Utility Model Content

[0005] To address the problems of fabric damage caused by passive dragging when unwinding fabric rolls, difficulty in maintaining constant fabric tension due to unwinding inertia during intermittent feeding, and dust formation caused by the dispersion of the protective powder layer on the fabric surface during feeding, this application provides a feeding device for ton bag processing.

[0006] The feeding device for ton bag processing provided in this application adopts the following technical solution: A feeding device for processing ton bags includes a support frame, a support mechanism, a drive assembly, and a dust collection assembly. The support mechanism includes a material-bearing rod and a limiting plate. The material-bearing rod is mounted on the support frame and has a fabric roll on it. The limiting plate is mounted on the material-bearing rod and is used to limit the fabric roll. The material-bearing rod has a serrated groove, and the limiting plate has a limiting spring pin. The end of the limiting spring pin has a locking block that engages with the serrated groove. The drive assembly is mounted on the support frame and includes a drive motor and a sliding sleeve. The drive motor is mounted on the support frame. The sliding sleeve is mounted on the power output end of the drive motor. A positioning spring pin is provided on the sliding sleeve to position it on the material support rod. The drive motor drives the material support rod to rotate. The dust collection assembly includes a vacuum cleaner, a dust collection connecting pipe, and a dust collection support box. Both the vacuum cleaner and the dust collection support box are mounted on a support frame. The dust collection support box has a dust collection container with a dust collection port facing the fabric sheet. The dust collection connecting pipe is positioned between the dust collection container and the vacuum cleaner. The dust collection support box also has a windproof roller located on one side of the dust collection container.

[0007] By adopting the above technical solution, the support mechanism fixes the fabric roll with a support rod and a limiting plate. The locking engagement of the limiting spring pin and the serrated groove achieves rapid axial positioning of the fabric roll, preventing it from shifting during rotation. The drive assembly actively drives the support rod to rotate via a drive motor, enabling the active unwinding of the fabric roll and preventing tearing or deformation of the fabric sheet caused by dragging. The dust collection assembly uses a vacuum cleaner and a dust collection support box to adsorb impurities on the surface of the fabric sheet. The wind shielding roller assists in creating a relatively closed dust collection environment, improving dust collection efficiency.

[0008] Preferably, the support mechanism further includes a lifting assembly, which includes a lifting cylinder and a lifting actuator. The lifting cylinder is vertically arranged, and its end is rotatably mounted on the support frame. The lifting actuator is rotatably mounted on the support frame, and the end of the piston rod of the lifting cylinder is rotatably mounted with one end of the lifting actuator. The material support rod is mounted on the other end of the lifting actuator. The drive motor is mounted on the lifting actuator.

[0009] By adopting the above technical solution, the lifting assembly adjusts the position of the lifting execution frame through the lifting cylinder, which facilitates the loading and unloading of the material support rod, reduces labor intensity, and improves the efficiency of cloth roll replacement.

[0010] Preferably, the other end of the lifting actuator is provided with a support groove, the support groove is an arc-shaped groove, and the bottom wall of the support groove is provided with ball bearings.

[0011] By adopting the above technical solution, the arc design of the support groove and the ball bearing reduce the frictional resistance when the support rod rotates, ensuring smooth rotation of the support rod and reducing drive energy consumption.

[0012] Preferably, the support mechanism further includes a tensioning assembly, which includes a tensioning support rod, a tensioning spring, and a tensioning roller. The tensioning support rod is slidably mounted on the support frame, and a tensioning spring is sleeved on the tensioning support rod. One end of the tensioning spring abuts against the tensioning support rod, and the other end of the tensioning spring abuts against the support frame. The tensioning roller is disposed at the end of the tensioning support rod and abuts against the fabric sheet.

[0013] By adopting the above technical solution, the tensioning assembly provides continuous pressure through the tensioning spring, so that the tensioning roller always contacts the fabric sheet, adapts to the tension changes during the intermittent feeding process, and maintains the stable tension of the fabric sheet.

[0014] Preferably, the drive assembly further includes a reducer, which is mounted on the drive motor. The sliding sleeve is mounted on the output shaft of the reducer. The end of the material support rod is configured as a prism segment, and the sliding sleeve has a sliding hexagonal groove that engages with the prism segment.

[0015] By adopting the above technical solution, the reducer adjusts the output speed and torque of the drive motor to ensure the smooth rotation of the fabric roll; the sliding sleeve and the prism section of the material support rod are interlocked to achieve reliable torque transmission and allow axial sliding, which facilitates installation and positioning.

[0016] Preferably, the dust collection support box is provided with a push support frame, and a push support rod is slidably arranged on the dust collection support box. A push spring is sleeved on the push support rod. One end of the push spring abuts against the push support frame, and the other end of the push spring abuts against the push support rod. The wind shield roller is rotatably arranged at the end of the push support rod.

[0017] By adopting the above technical solution, the push spring applies flexible pressure to the windproof roller through the push support rod, so that the windproof roller can adapt to fabric sheets of different thicknesses and avoid excessive compression that could damage the fabric surface.

[0018] Preferably, the dust collection assembly further includes a windproof support roller, which is disposed inside the dust collection support box and presses the fabric sheet onto the windproof support roller.

[0019] By adopting the above technical solution, the wind shielding roller and the wind shielding support roller work together to press the fabric sheet, forming an effective seal, preventing airflow short circuit, and ensuring that the dust suction airflow passes through the surface of the fabric sheet in a concentrated manner.

[0020] Preferably, the dust collection support box is equipped with windproof cotton.

[0021] By adopting the above technical solution, the windproof cotton further seals the dust removal chamber, reduces airflow leakage, and enhances the dust collection effect.

[0022] In summary, this application includes the following beneficial technical effects: The drive motor in the drive assembly actively drives the material support rod to rotate, achieving active unwinding of the fabric roll and avoiding tearing or deformation of the fabric sheet caused by direct dragging. The tensioning roller in the tensioning assembly continuously contacts the fabric sheet under the action of the tension spring, adapting to tension changes during intermittent feeding, maintaining stable fabric sheet tension, and improving dimensional consistency in subsequent sewing and cutting processes. The vacuum cleaner in the dust collection assembly forms a relatively closed dust collection chamber through the dust collection support box. The wind shielding roller and wind shielding support roller work together to press the fabric sheet, and the wind shielding cotton seals the gaps, allowing the suction airflow to concentrate and enter from the air inlet and pass through the fabric sheet, effectively adsorbing surface dust, reducing the dispersion of production dust, and improving the quality of the workshop environment.

[0031] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0032] This application discloses a feeding device for ton bag processing, referring to... Figure 1 It includes a support frame 1, a support mechanism 2, a drive assembly 3, and a dust collection assembly 4. The support mechanism 2, the drive assembly 3, and the dust collection assembly 4 are all mounted on the support frame 1. The support mechanism 2 is used to support the fabric roll 5, the drive assembly 3 is used to drive the fabric roll 5 to rotate, and the dust collection assembly 4 is used to absorb impurities on the fabric sheet 51.

[0033] Reference Figures 1-3 The support mechanism 2 includes a lifting assembly 21, a material support rod 22, a limiting plate 23, and a tensioning assembly 24. The lifting assembly 21 includes a lifting cylinder 211 and a lifting execution frame 212. The lifting cylinder 211 is vertically mounted on the support frame 1. The upper end of the lifting cylinder 211 is rotatably connected to the support frame 1. The piston rod of the lifting cylinder 211 is located at the lower end of the lifting cylinder 211. The middle part of the lifting execution frame 212 is rotatably connected to the support frame 1. The end of the piston rod of the lifting cylinder 211 is rotatably connected to one end of the lifting execution frame 212. The other end of the lifting execution frame 212 is provided with a support groove 2121. The support groove 2121 is an arc-shaped groove, and multiple balls 2122 are rotatably connected to the inner wall of the arc-shaped groove.

[0034] Reference Figures 2-4In this embodiment, the material support rod 22 is mounted on the lifting actuator 212. Specifically, the portion of the material support rod 22 that contacts the support groove 2121 is designed as a cylindrical section, on which an annular groove 221 is formed. The material support rod 22 is engaged with the lifting actuator 212 through the annular groove 221, such that the bottom wall of the annular groove 221 mates with the bottom wall of the support groove 2121, thereby restricting the axial movement of the material support rod 22. Multiple ball bearings 2122 are rotatably connected to the inner wall of the support groove 2121, and these ball bearings 2122 are in direct contact with the bottom wall of the annular groove 221. When the material support rod 22 rotates, the ball bearings 2122 roll on the bottom wall of the annular groove 221, significantly reducing the friction between the material support rod 22 and the support groove 2121, ensuring smooth rotation of the material support rod 22.

[0035] Reference Figure 1 , Figure 4 and Figure 5 The remaining portion of the support rod 22 consists of prism segments 222. In this embodiment, the prism segment 222 is a hexagonal prism segment. A serrated groove 223 is provided on the side wall of the prism segment 222. A matching hexagonal groove 521 is provided on the roll 52 of the fabric roll 5. The fabric roll 5 is slidably connected to the support rod 22. Two limiting discs 23 are sleeved on the support rod 22, symmetrically arranged on the support rod 22. The limiting discs 23 are used to restrict the axial movement of the fabric roll 5 on the support rod 22. This embodiment uses one of the limiting discs 23 as an example. A limiting spring pin 231 is vertically slidably connected to the side wall of the limiting disc 23 away from the fabric roll 5. A locking block 2311 is fixedly connected to the lower end of the limiting spring pin 231. The cross-section of the locking block 2311 is serrated.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The drive assembly 3 includes a drive motor 31, a reducer 32, and a sliding sleeve 33. The drive motor 31 is fixedly connected to the lifting actuator 212, the reducer 32 is fixedly connected to the drive motor 31, and the sliding sleeve 33 is sleeved on the output shaft of the reducer 32. In this embodiment, the output shaft of the reducer 32 is a drive hexagonal prism, and the sliding sleeve 33 has a sliding hexagonal groove 332 along its own axis. The sliding hexagonal groove 332 can slide and engage with the output shaft of the reducer 32, and can also slide and engage with the material support rod 22. A positioning spring pin 331 is also vertically fixedly connected to the sliding sleeve 33. The pin of the positioning spring pin 331 can extend from the side wall of the sliding sleeve 33 into the sliding hexagonal groove 332. The positioning spring pin 331 is used to position the sliding sleeve 33 on the material support rod 22. The material support rod 22 has a positioning hole 2221 that engages with the positioning spring pin 331.

[0037] Reference Figure 1 , Figure 3 and Figure 4 When the fabric roll 5 needs to be installed on the support frame 1, the support rod 22 is first removed from the lifting actuator 212. Then, one of the limiting plates 23 is removed from the support rod 22. Next, the mating hexagonal groove 521 of the fabric roll 5 is aligned with the hexagonal prism section of the support rod 22 and fitted onto it. The mating of the hexagonal groove 521 and the hexagonal prism section restricts the relative rotation between the fabric roll 5 and the support rod 22. Then, the limiting plate 23 is fitted back onto the support rod 22, and its end face is aligned with the end of the fabric roll 5, thereby restricting the axial movement of the fabric roll 5 along the support rod 22. During this process, the limiting spring pin 231 on the limiting plate 23, under its own elastic force, drives the locking block 2311 at its lower end to automatically engage with the serrated groove 223 on the hexagonal prism section 222 of the support rod 22. Because the cross-section of the locking block 2311 is serrated, this structure allows the limiting plate 23 to slide unidirectionally along the material support rod 22 toward the fabric roll 5 and lock automatically; when it is necessary to move the limiting plate 23 in the opposite direction, the limiting spring pin 231 should be pulled away from the material support rod 22 so that the locking block 2311 can be released from the serrated groove 223.

[0038] Reference Figure 1 , Figure 3 and Figure 4 After the fabric roll 5 is installed on the support rod 22, the lifting cylinder 211 is operated to retract its piston rod, causing the lifting actuator 212 to deflect around its central rotating connection point with the support frame 1. This causes the end of the lifting actuator 212 with the support groove 2121 to move downward to a position where it can easily receive the support rod 22. Then, the support rod 22, equipped with the fabric roll 5 and the limiting plate 23, is placed on the lifting actuator 212, ensuring that the cylindrical section of the support rod 22 is in contact with the ball bearings 2122 on the inner wall of the support groove 2121. Next, the sliding hexagonal groove 332 of the sliding sleeve 33 is aligned with and inserted into the hexagonal prism section at the end of the support rod 22. The sliding sleeve 33 is then pushed to move axially along the support rod 22 to the desired position. At this time, the pin of the positioning spring pin 331 automatically springs into the corresponding positioning hole 2221 on the support rod 22, thus fixing the sliding sleeve 33 onto the support rod 22. This completes the installation of the entire fabric roll 5.

[0039] Reference Figures 1-2The tensioning assembly 24 is used to tension the fabric sheet 51. In this embodiment, two sets of tensioning assemblies 24 are provided. One set of tensioning assemblies 24 is located below the support frame 1, and the other set of tensioning assemblies 24 is located above the support frame 1. This embodiment takes the tensioning assembly 24 located above as an example. The tensioning assembly 24 includes a tensioning support rod 241, a tensioning spring 242, and a tensioning roller 243. The tensioning support rod 241 is vertically slidably connected to the support frame 1. A tensioning limiting block 2411 is fixedly connected to the tensioning support rod 241. The tensioning spring 242 is sleeved on the tensioning limiting block 2411. One end of the tensioning spring 242 abuts against the support frame 1, and the other end of the tensioning spring 242 abuts against the tensioning limiting block 2411. The tensioning roller 243 is rotatably connected to the upper end of the tensioning support rod 241 and abuts against the lower surface of the fabric sheet 51.

[0040] Reference Figures 1-2 The support frame 1 is equipped with a first guide roller 11, a second guide roller 12, a third guide roller 13, and a fourth guide roller 14. These guide rollers work together to guide the fabric sheet 51 along a predetermined path, ensuring that the fabric sheet 51 remains stable and taut during feeding. The first guide roller 11 is located between the upper tensioning assembly 24 and the material support rod 22. The function of the first guide roller 11 is to guide the fabric sheet 51 unwound from the fabric roll 5 towards the upper tensioning assembly 24, causing the fabric sheet 51 to initially change direction and enter the tensioning area. The second guide roller 12 is located above and to one side of the lower tensioning assembly 24. The second guide roller 12 is used to receive the fabric sheet 51 from the lower tensioning assembly 24 and turn it downwards. The third guide roller 13 is located below the second guide roller 12, and the fourth guide roller 14 is located above the third guide roller 13. The fourth guide roller 14 is used to guide the fabric sheet 51 towards the dust collection assembly 4.

[0041] Reference Figure 1 , Figure 6 and Figure 7The vacuuming assembly 4 includes a vacuum cleaner 41, a vacuuming connecting pipe 42, a vacuuming support box 43, a push spring 44, a wind shield roller 45, and a wind shield support roller 46. The vacuum cleaner 41 is fixedly connected to the support frame 1, and the vacuuming support box 43 is fixedly connected to the support frame 1. In this embodiment, two vacuuming support boxes 43 are arranged side by side. One vacuuming support box 43 is used to absorb impurities on the upper surface of the fabric sheet 51, and the other vacuuming support box 43 is used to absorb impurities on the lower surface of the fabric sheet 51. This embodiment takes the vacuuming support box 43 that absorbs impurities on the upper surface of the fabric sheet 51 as an example. A push support frame 431 is fixedly connected to the upper end of the vacuuming support box 43, and a push support rod 432 is also vertically slidably connected to the vacuuming support box 43. The push support rod 432 also slides with the push support frame 431. A push-support block 4321 is fixedly connected to the push-support rod 432. The push-support block 4321 is located between the inner top wall of the push-support frame 431 and the outer top wall of the dust collection support box 43. A push-spring 44 is sleeved on the push-support rod 432. One end of the push-spring 44 abuts against the push-support block 4321, and the other end abuts against the inner top wall of the push-support frame 431. A wind shield roller 45 is rotatably connected to the lower end of the push-support rod 432, and a wind shield roller 46 is rotatably connected inside the dust collection support box 43, with the wind shield roller 46 located below the wind shield roller 45. The wind shield roller 45 is used to press the fabric sheet 51 tightly onto the wind shield roller 46. Two sets of such pressed wind shield rollers 45 and wind shield rollers 46 are provided, and the two sets of pressed wind shield rollers 45 and wind shield rollers 46 are respectively located at the inlet and outlet of the dust collection support box 43.

[0042] Reference Figure 1 , Figure 6 and Figure 7 The dust collection support box 43 has windproof cotton 435 fixedly connected to both its inlet and outlet. The windproof cotton 435 is attached to the side wall of the windproof roller 45 and the windproof support roller 46, and is in contact with them. A dust collection box 433 is vertically fixedly connected to the top wall of the dust collection support box 43, with its lower end extending into the box. A suction port 4331 is provided at the lower end of the dust collection box 433, and the dust collection box 433 is fixedly connected to the vacuum cleaner 41 via a suction connecting pipe 42. An air inlet 434 is provided on the bottom wall of the dust collection support box 43, located directly below the suction port 4331.

[0043] Reference Figure 1 , Figure 6 and Figure 7The combination of the wind-shielding rollers 45 and 46, along with the wind-shielding cotton 435, located at the inlet and outlet of the dust collection support box 43, effectively forms a relatively enclosed dust collection chamber. This structure reduces interference from external air and prevents short-circuiting of the internal airflow, ensuring that the suction airflow is concentrated and enters from the air inlet 434 on the bottom wall. Since the air inlet 434 is located directly below the suction port 4331 of the dust collection box 433, the airflow is forced to pass through the fabric sheet 51 when the vacuum cleaner 41 is working. This directional airflow path can efficiently peel off and carry away dust and impurities attached to the surface of the fabric sheet 51, thereby significantly improving dust collection efficiency and cleaning effect. While ensuring efficient dust collection, this design, through the flexible pressure provided by the movable wind-shielding rollers 45 and springs, can adapt to fabric sheets 51 of different thicknesses, avoiding damage to the fabric surface that may be caused by excessive compression, achieving a balance between high efficiency and flexible processing.

[0044] The implementation principle of the feeding device for ton bag processing disclosed in this application embodiment is as follows: The support mechanism 2 adjusts the position of the supporting rod 22 through the lifting component 21 to facilitate the loading and unloading of the fabric roll 5. The hexagonal prism section of the supporting rod 22 cooperates with the hexagonal groove 521 of the roll shaft 52 of the fabric roll 5, thereby limiting relative rotation. The limiting plate 23 is engaged with the serrated groove 223 on the supporting rod 22 through the limiting spring pin 231 and the locking block 2311, thereby fixing the axial position of the fabric roll 5. The driving component 3 is connected to the supporting rod 22 through the sliding sleeve 33. The driving motor 31 outputs power through the reducer 32 to drive the fabric roll 5 to rotate actively, realizing the smooth output of the fabric sheet 51 and avoiding mechanical damage caused by direct dragging.

[0045] The tensioning assembly 24 contacts the fabric sheet 51 via the tensioning roller 243. The tensioning spring 242 provides continuous pressure to adapt to changes in the tension of the fabric sheet 51, maintaining stable tension during intermittent feeding and reducing the impact of fluctuations on subsequent processing accuracy. The guide rollers include a first guide roller 11, a second guide roller 12, a third guide roller 13, and a fourth guide roller 14, which work together to guide the fabric sheet 51 along a predetermined path, ensuring smooth feeding.

[0046] The dust collection assembly 4 forms a relatively enclosed dust collection chamber through the dust collection support box 43. A wind shield roller 45 and a wind shield support roller 46 are combined and positioned at the inlet and outlet, with wind shield cotton 435 filling the end of the wind shield roller 45 to prevent airflow short-circuiting. The vacuum cleaner 41 is connected to the dust collection box 433 via a dust collection connecting pipe 42. The dust collection port 4331 is located directly above the air inlet 434, and the airflow passes vertically through the fabric sheet 51, efficiently adsorbing surface dust.

[0047] This application utilizes the drive component 3 to actively unwind the fabric, avoiding tearing or deformation caused by dragging. The application of the tensioning component 24 ensures stable tension of the fabric sheet 51, improving dimensional consistency during sewing and cutting. The dust collection component 4 is designed to effectively collect the protective dust layer on the surface of the fabric sheet 51, reducing the dispersion of production dust and improving the quality of the workshop environment.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
