Description

Technical Field

[0001] This application relates to the technical field of filter mesh bag production equipment, specifically an environmentally friendly filter mesh bag production edge rolling device. Background Technology

[0002] Filter bags, as an environmentally friendly product widely used in water treatment, agricultural irrigation, and aquaculture, directly affect the filtration effect of water resources and environmental sustainability. During the production of filter bags, to ensure the strength and durability of the ends, a rolled edge process is usually required. This step not only strengthens the ends of the bag, preventing damage due to excessive friction or tension during use, but also improves the overall aesthetics of the bag.

[0003] However, currently, the edge-rolling operation of filter bags is mostly done manually. Workers need to use specialized tools or equipment to repeatedly rotate and squeeze the edges of the bag to roll them up. Manual edge-rolling requires workers to maintain a high level of concentration and steady hand movements for extended periods to ensure quality and consistency. However, during long production runs, workers' wrists and fingers are prone to soreness and fatigue due to continuous repetitive movements, which not only reduces work efficiency but may also lead to occupational diseases and workplace injuries.

[0004] Therefore, this application provides an environmentally friendly filter bag production edge-rolling device to solve the above problems. Utility Model Content

[0005] This application provides an environmentally friendly filter bag production edge-rolling device, which aims to solve the problem that the existing filter bag production edge-rolling methods mentioned in the background technology all use manual edge-rolling. During the long production process, workers' wrists and fingers are easily sore and fatigued due to continuous repetitive movements. This not only reduces the workers' work efficiency, but may also cause occupational diseases and work-related accidents.

[0006] To achieve the above objectives, this application provides the following technical solution: an environmentally friendly filter bag production edge-rolling device, comprising a base, a sleeve disposed on the base, an insertion rod inserted into the sleeve at one end away from the base, and a drive structure disposed on the base for driving the insertion rod to move up and down along the sleeve;

[0007] To facilitate the lifting and lowering movement of the insert rod, the drive structure includes an electric push rod fixedly mounted on the base and connected to the insert rod, and a control switch mounted on the base and electrically connected to the electric push rod for controlling the lifting and lowering movement of the electric push rod. In use, the electric push rod is first activated via the control switch, causing its output end to lift the insert rod until it is completely detached from the sleeve and positioned above it. At this point, the operator can place the filter bag to be rolled onto the top of the sleeve. Next, the electric push rod is activated again via the control switch, causing its output end to slowly lower the insert rod. During this downward movement, the insert rod contacts the top of the filter bag and, as it continues to descend, pushes the filter bag inward into the sleeve. Due to the fixing effect of the sleeve, the filter bag gradually flips inward under the pushing force of the insert rod, thus achieving the rolling operation. During the rolling process, the operator can observe the rolling of the filter bag and adjust the control switch accordingly to control the downward speed and force of the insert rod. After the edge-rolling operation is completed, the operator can use the control switch to make the output end of the electric push rod drive the insert rod to rise, and pull the insert rod out of the sleeve so that the next round of edge-rolling operation can be carried out.

[0008] Preferably, to facilitate the fixed connection between the insert rod and the output end of the electric actuator: a connecting plate is fixedly connected to the end of the insert rod away from the sleeve, which is also fixedly connected to the output end of the electric actuator. The design of the connecting plate makes the connection between the insert rod and the electric actuator more stable, avoiding errors or malfunctions caused by loosening during the crimping process. The introduction of the connecting plate makes the connection between the insert rod and the electric actuator simpler and more convenient, and also facilitates subsequent maintenance and replacement work.

[0009] Preferably, to prevent the insert rod from rotating circumferentially around its output end when the electric push rod drives the insertion rod to rise and fall, and to ensure that the insertion rod maintains vertical rising and falling motion, the base is provided with a limiting mechanism to prevent circumferential rotation of the output end of the electric push rod. The limiting mechanism includes a fixed cylinder fixedly connected to one end of the base near the sleeve, and a limiting rod inserted into the fixed cylinder and fixedly connected to the connecting plate. The design of the limiting mechanism effectively prevents the insertion rod from rotating circumferentially around the output end of the electric push rod during rising and falling, ensuring that the insertion rod always maintains vertical rising and falling motion, thereby improving the accuracy and stability of the crimping operation.

[0010] Preferably, to prevent severe sliding between the base and the tabletop: the bottom of the base is provided with several support legs, and the bottom of each support leg is fixedly connected to an anti-slip pad. The anti-slip pad is made of rubber material with a high coefficient of friction, which can effectively increase the friction between the device and the tabletop, preventing the device from sliding during use, thereby ensuring the accuracy and stability of the curling operation.

[0011] Preferably, to enable the sleeve to perform edge-rolling operations on filter bags of different lengths, the sleeve is internally equipped with a positioning mechanism for positioning the height of the insertion rod. This positioning mechanism includes a limit switch inserted inside the sleeve, a locking rod inserted inside the limit switch, a telescopic component located within the limit switch and connected to the locking rod for driving the two locking rods away from each other, and several locking slots symmetrically formed on the sleeve along the vertical direction. Through the combined use of the locking rod and locking slots, precise locking of the insertion rod's height position inside the sleeve can be achieved, allowing the sleeve to perform edge-rolling operations on filter bags of different lengths, greatly improving the applicability and flexibility of the device.

[0012] Preferably, the telescopic component includes a limiting groove formed within the limiting switch, limiting plates symmetrically slidably disposed within the limiting groove, and a fastening spring disposed between the two limiting plates. The cooperation of the limiting groove and the limiting plates ensures that the telescopic component maintains a stable movement trajectory during extension and retraction, avoiding locking failure due to shaking or displacement.

[0013] This application utilizes a semi-automatic mechanical mechanism to roll the edges of the filter bags, replacing the traditional manual rolling method. This reduces the labor intensity of operators, avoids problems such as wrist pain caused by prolonged repetitive operations, and significantly improves production efficiency while reducing labor costs. Simultaneously rolling the edges also completes the turning operation of the filter bags, reducing the turning step in traditional processes and further improving production efficiency.

[0014] This application, through the combined use of a locking rod and a locking groove, can achieve precise locking of the height position of the insertion rod inside the sleeve, enabling the sleeve to perform edge-rolling operations on filter bags of different lengths, greatly improving the applicability and flexibility of the device.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] This embodiment provides an environmentally friendly filter mesh bag production edge-rolling device, such as... Figure 1-3 As shown, the hemming device includes a base 1, a sleeve 2 disposed on the base 1, an insert rod 3 inserted into the sleeve 2 at one end away from the base 1, and a drive structure 4 disposed on the base 1 for driving the insert rod 3 to move up and down along the sleeve 2.

[0022] To facilitate the lifting and lowering movement of the insertion rod 3, the drive structure 4 includes an electric push rod 41 fixedly mounted on the base 1 and connected to the insertion rod 3, and a control switch 42 mounted on the base 1 and electrically connected to the electric push rod 41 for controlling the lifting and lowering movement of the electric push rod 41. The semi-automatic mechanical mechanism performs the edge-rolling operation on the filter bag, replacing the traditional manual edge-rolling method, reducing the labor intensity of operators, avoiding problems such as wrist pain caused by prolonged repetitive operations, significantly improving production efficiency, and reducing labor costs. Simultaneously with edge-rolling, the filter bag is turned over, reducing the turning process in traditional processes and further improving production efficiency. In use, first, the electric push rod 41 is activated via the control switch 42, causing the output end of the electric push rod 41 to drive the insertion rod 3 upwards until the insertion rod 3 is completely detached from the sleeve 2 and positioned above the sleeve 2. At this point, the operator can place the filter bag to be edge-rolled onto the top of the sleeve 2. Then, the electric push rod 41 is activated again via the control switch 42, causing the output end of the electric push rod 41 to slowly lower the insertion rod 3. As the insertion rod 3 moves downward, it contacts the top of the filter bag and pushes the filter bag into the sleeve 2. Due to the fixing effect of the sleeve 2, the filter bag gradually flips inward under the pushing force of the insertion rod 3, thus achieving the edge-rolling operation. During the edge-rolling process, the operator can observe the edge-rolling condition of the filter bag and adjust the control switch 42 as needed to control the downward speed and force of the insertion rod 3. After the edge-rolling operation is completed, the operator can use the control switch 42 to cause the output end of the electric push rod 41 to drive the insertion rod 3 upward, pulling the insertion rod 3 out of the sleeve 2 for the next round of edge-rolling operation.

[0023] Specifically, to facilitate the fixed connection between the insertion rod 3 and the output end of the electric push rod 41, a connecting plate 31, which is fixedly connected to the output end of the electric push rod 41, is fixedly connected to the end of the insertion rod 3 furthest from the sleeve 2. The design of the connecting plate 31 makes the connection between the insertion rod 3 and the electric push rod 41 more stable, avoiding errors or malfunctions caused by loose connections during the edge-rolling process. The introduction of the connecting plate 31 makes the connection between the insertion rod 3 and the electric push rod 41 simpler and more convenient, and also facilitates subsequent maintenance and replacement. Under the action of the connecting plate 31, the connection between the insertion rod 3 and the electric push rod 41 becomes more stable and reliable. When the electric push rod 41 receives the command from the control switch 42, its output end will begin to extend and retract. Due to the fixed connection effect of the connecting plate 31, the insertion rod 3 will rise or fall synchronously with the extension and retraction of the output end of the electric push rod 41. During the edge-rolling process, when the output end of the electric push rod 41 extends, the insertion rod 3 will rise accordingly, providing sufficient space for the filter bag to be fitted. When the filter bag is fitted and ready for edge rolling, the output end of the electric push rod 41 retracts, causing the insertion rod 3 and connecting plate 31 to descend together. During descent, the insertion rod 3 gradually pushes the filter bag into the sleeve 2, and the edge rolling operation is achieved as the insertion rod 3 continues to descend. Due to the presence of the connecting plate 31, the connection between the insertion rod 3 and the electric push rod 41 is tighter and more stable, thus ensuring the accuracy and reliability of the edge rolling operation.

[0024] Furthermore, to prevent the electric push rod 41 from rotating circumferentially around the output end of the insert rod 3 during its lifting and lowering motion, and to ensure that the insert rod 3 maintains vertical lifting and lowering motion, a limiting mechanism 5 is provided on the base 1 to prevent circumferential rotation of the output end of the electric push rod 41. The limiting mechanism 5 includes a fixed cylinder 51 fixedly connected to one end of the base 1 near the sleeve 2, and a limiting rod 52 inserted into the fixed cylinder 51 and fixedly connected to the connecting plate 31. The design of the limiting mechanism 5 effectively prevents the insert rod 3 from rotating circumferentially around the output end of the electric push rod 41 during lifting and lowering, ensuring that the insert rod 3 always maintains vertical lifting and lowering motion, thereby improving the accuracy and stability of the hemming operation. The introduction of the limiting mechanism 5 eliminates the need for operators to constantly monitor the rotation of the insert rod 3 during the hemming process, thus simplifying the operation process and improving work efficiency. Under the action of the limiting mechanism 5, the insert rod 3 always remains vertical during lifting and lowering, avoiding circumferential rotation around the output end of the electric push rod 41. When the electric push rod 41 receives a command from the control switch 42 and begins to extend or retract, its output end will drive the connecting plate 31 and the fixedly connected insertion rod 3 to rise or fall together. During this process, the limiting rod 52 is always inserted into the fixed cylinder 51, which restricts the circumferential rotation of the insertion rod 3. Due to the fixed connection between the limiting rod 52 and the connecting plate 31, the insertion rod 3 will maintain vertical movement consistent with the limiting rod 52 during the lifting and lowering process, thereby ensuring the accuracy and stability of the hemming operation.

[0025] Specifically, to prevent severe sliding between the base 1 and the work surface, the base 1 has several support legs 6 at its bottom, with anti-slip pads 61 fixedly connected to the bottom of each support leg 6. The anti-slip pads 61 are made of high-friction rubber material, effectively increasing friction with the work surface and preventing slippage during use, thus ensuring the accuracy and stability of the curling operation. The anti-slip pads 61 not only increase friction and prevent slippage but also protect the work surface, preventing scratches or damage during use. When the device is placed on the work surface, the support legs 6 first contact the surface and support the entire device through their stable structure. At this time, the anti-slip pads 61 adhere tightly to the work surface, effectively increasing friction between the device and the work surface using their high coefficient of friction. During the curling process, even if the device is subjected to vibration or external force, the anti-slip pads 61 provide sufficient resistance to prevent severe sliding between the base 1 and the work surface. This allows the operator to focus more on the curling operation itself without worrying about the device's stability. When the device needs to be moved to another location, the operator can easily lift it without worrying that the anti-slip mat 61 will damage the table or leave hard-to-remove marks.

[0026] To enable the sleeve 2 to hem filter bags of different lengths, a positioning mechanism 7 is installed inside the sleeve 2 to position the height of the insertion rod 3. The positioning mechanism 7 includes a limit switch 71 inserted inside the sleeve 2, a locking rod 72 inserted inside the limit switch 71, a telescopic component 73 located inside the limit switch 71 and connected to the locking rod 72 for driving the two locking rods 72 away from each other, and several locking slots 74 symmetrically formed on the sleeve 2 in the vertical direction. Through the cooperation of the locking rod 72 and the locking slots 74, the height position of the insertion rod 3 inside the sleeve 2 can be precisely locked, allowing the sleeve 2 to hem filter bags of different lengths, greatly improving the applicability and flexibility of the device. When it is necessary to adjust the height position of the insertion rod 3 to accommodate filter bags of different lengths, the operator can first adjust the position of the limit switch 71. By moving the limit switch 71, the locking rod 72 inside can be aligned with the corresponding locking slot 74 on the sleeve 2. Next, the operator can drive the locking rod 72 by controlling the extension and retraction of the telescopic component 73. When the telescopic component 73 extends, it pushes the two locking rods 72 away from each other and inserts them into the corresponding locking slots 74. At this time, the cooperation between the locking rods 72 and the locking slots 74 achieves precise locking of the height position of the insertion rod 3. During the hemming process, even if the insertion rod 3 is subjected to external force or vibration, the insertion rod 3 will always maintain a stable height position due to the firm connection between the locking rods 72 and the locking slots 74, thus ensuring the accuracy and stability of the hemming operation. When it is necessary to adjust the height position of the insertion rod 3 to accommodate the next length of filter bag, the operator only needs to readjust the position of the limit switch 71 and select the appropriate locking slot 74 for locking. In this way, the hemming requirements for filter bags of different lengths can be met through simple adjustment operations.

[0027] Furthermore, the telescopic component 73 includes a limiting groove 731 formed within the limiting switch 71, limiting plates 732 symmetrically slidably disposed within the limiting groove 731, and a fastening spring 733 disposed between the two limiting plates 732. Through the cooperative use of the limiting groove 731 and the limiting plates 732, the telescopic component 73 can maintain a stable movement trajectory during telescopic movement, avoiding locking failure due to shaking or displacement. The introduction of the fastening spring 733 ensures that the locking rod 72 maintains a tight connection when inserted into the locking groove 74, effectively preventing rolling operation failure due to loosening or detachment. The fastening spring 733 is initially in a compressed and charged state. In the initial state, the elastic force of the fastening spring 733 causes the two limiting plates 732 to maintain an outward tendency, thereby driving the locking rod 72 to be tightly inserted into the locking groove 74. At this time, the firm connection between the locking rod 72 and the locking groove 74 achieves precise locking of the height position of the insertion rod 3. When unlocking is required, the operator can use external force (such as manual pressing) to move the two limit plates 732 relative to each other. During this process, the fastening spring 733 will be compressed, and the locking lever 72 will gradually disengage from the locking groove 74.

[0028] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
