Description

Technical Field

[0001] This utility model relates to the technical field of filter material processing equipment, and in particular to a device for cutting the corners of a cylindrical filter bag. Background Technology

[0002] Cylindrical filter bags are key components in industrial dust removal and liquid filtration. During the manufacturing process, the edges or corners often need to be precisely cut to meet the requirements of installation and sealing.

[0003] Currently, automated equipment used to perform such cutting tasks typically relies on independent motors or pneumatic components as power sources to drive the cutting tools. While this design enables automated cutting, it also leads to a more complex overall structure, increases manufacturing costs and operating energy consumption, and is not optimal in situations where structural simplification and energy saving are desired.

[0004] Furthermore, existing cutting devices often have a fixed spacing between the components used to press or convey filter bags. However, cylindrical filter bags come in a variety of material specifications, and different batches or models of filter bags have significantly different material thicknesses. The fixed spacing design makes it difficult for the equipment to adapt to these variations. When processing thicker materials, it results in excessive conveying resistance or failure to feed the bags in. When processing thinner materials, it leads to insufficient pressing force, slippage, or reduced cutting accuracy. This greatly limits the versatility and applicability of the equipment.

[0005] Therefore, this utility model proposes a cylindrical filter bag edge cutting device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing cylindrical filter bag edge trimming devices, such as fixed structure that cannot be flexibly adjusted according to material thickness, and the need for an independent power source that leads to complex structure and high energy consumption, this utility model aims to provide a cylindrical filter bag edge trimming device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a cylindrical filter bag edge cutting device, including: a support frame, an adjustment mechanism, and a cutting mechanism.

[0008] The adjustment mechanism includes a sliding plate slidably connected to the support frame, a coupling disposed on the sliding plate, a locking block disposed on the coupling, and a locking slot opened on the support frame.

[0009] Furthermore, the cutting mechanism includes a rotating wheel, a T-shaped column, a damping telescopic rod, a turntable, a fixed shaft, cutting shears, a sliding groove, and a sliding block. The rotating wheel is rotatably connected to the sliding plate, the cutting shears are rotatably connected to the fixed shaft, and the fixed shaft is fixed to the support frame.

[0010] Preferably, the T-shaped column is fixedly connected to the inner wall of the rotating wheel.

[0011] Preferably, one end of the damping telescopic rod is rotatably connected to the top of the T-shaped column, and the other end of the damping telescopic rod is rotatably connected to the turntable.

[0012] Preferably, the fixed shaft is fixedly connected to the inner wall of the support frame, and the cutting shears are rotatably connected to the outer wall of the fixed shaft.

[0013] Preferably, the sliding block is rotatably connected to the turntable, and the sliding block is rotatably connected to the inner wall of the sliding groove.

[0014] Preferably, the sliding plate is slidably connected to the inner wall of the support frame.

[0015] Preferably, the coupling is fixedly connected to the top of the sliding plate.

[0016] Preferably, the locking block is rotatably connected to the inner wall of the coupling.

[0017] Preferably, the number of the rotating wheel, T-shaped column, damping telescopic rod, sliding block, cutting shears, sliding groove, turntable, sliding plate, coupling and locking block are all two.

[0018] Preferably, the number of the checkpoints is multiple.

[0019] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art where the cutting device has a fixed structure and cannot adjust the pressing distance according to the thickness of the filter bag material, resulting in a limited range of applications. It is achieved by setting a sliding plate that can slide on the support frame and installing a rotating wheel on the sliding plate. The adjustment mechanism locks the position of the sliding plate through the cooperation of the locking block and the locking slot.

[0020] 2. This utility model, by setting up a rotating wheel and using the friction force generated between the filter bag and the rotating wheel during the conveying process as power, and then driving the cutting shears through a mechanical transmission mechanism composed of a T-shaped column, a damping telescopic rod, a turntable, a sliding block and a sliding groove, solves the problem that the cutting device in the prior art must be equipped with an independent motor drive, resulting in complex structure, high cost and additional energy consumption. It achieves automatic cutting by synchronously using the kinetic energy of material conveying, without the need for an additional power source, thereby simplifying the equipment structure and saving energy.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example: Please refer to Figures 1 to 6 This utility model provides a cylindrical filter bag edge cutting device, which aims to solve the problems of existing cylindrical filter bag cutting equipment being unable to flexibly adjust the spacing according to the material thickness and having a complex transmission structure that leads to low cutting efficiency.

[0025] like Figures 1 to 6As shown, a cylindrical filter bag edge trimming device includes a support frame 1, which serves as the main support structure for mounting other components. An adjustment mechanism 3 is provided on the inner wall of the support frame 1. The adjustment mechanism 3 adjusts the spacing between the internal components to accommodate cylindrical filter bag materials of different thicknesses. The adjustment mechanism 3 includes two sliding plates 301, which are slidably connected to both sides of the inner wall of the support frame 1. The sliding plates 301 can reciprocate within the inner wall of the support frame 1. A coupling 302 is fixedly connected to the top of each sliding plate 301, and the coupling 302 moves synchronously with the sliding plate 301. A locking block 303 is rotatably connected to the inner wall of each coupling 302. The device can rotate around the axis of the coupling 302. Multiple slots 304 are provided on the top of the support frame 1 corresponding to the position of the locking block 303. These slots 304 are arranged in a linear array along the sliding direction of the sliding plate 301. The locking block 303 can engage with any slot 304. Rotating the locking block 303 into the slot 304 restricts the position of the sliding plate 301. A cylindrical filter bag edge cutting device also includes a cutting mechanism 2. The cutting mechanism 2 is used to cut the edges of the cylindrical filter bag. The cutting mechanism 2 includes a rotating wheel 201, a T-shaped column 202, a damping telescopic rod 203, a turntable 208, a fixed shaft 205, cutting shears 206, a sliding groove 207, and sliding blocks 204. The number of rotating wheels 201 is... Two rotating wheels 201 are rotatably connected to the inner walls of two sliding plates 301, respectively. The two rotating wheels 201 are arranged opposite each other and can rotate freely within the sliding plates 301. The movement of the sliding plates 301 can change the position of the rotating wheels 201, thereby adjusting the distance between the two rotating wheels 201. A T-shaped post 202 is fixedly connected to the inner wall of each rotating wheel 201. The T-shaped post 202 is coaxially arranged with the rotating wheel 201 and rotates synchronously with the rotating wheel 201. One end of a damping telescopic rod 203 is rotatably connected to the top of each T-shaped post 202, and the other end of the damping telescopic rod 203 is rotatably connected to a turntable 208. The damping telescopic rod 203 can extend according to the change in distance between the T-shaped post 202 and the turntable 208. The turntable 208 is rotatably connected to a structure associated with the support frame 1 or the sliding plate 301 to receive power and rotate. A fixed shaft 205 is fixedly connected to the inner wall of the support frame 1, and its position is relatively fixed and does not move with the sliding plate 301. A cutting shear 206 is rotatably connected to the outer wall of the fixed shaft 205. The cutting shear 206 can perform a swing-type cutting action around the fixed shaft 205. A sliding groove 207 is provided at the top of the cutting shear 206, extending along its length. A sliding block 204 is rotatably connected to the end face of the turntable 208, and simultaneously slidably connected to the inner wall of the sliding groove 207. When the turntable 208 rotates, it drives the sliding block 204 to perform a circular motion.The sliding block 204 slides within the sliding groove 207, simultaneously pushing the cutting shears 206 to reciprocate around the fixed axis 205.

[0026] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The cutting mechanism 2, as the core component for realizing the cutting action, mainly includes a rotating wheel 201, a T-shaped column 202, a damping telescopic rod 203, a sliding block 204, a fixed shaft 205, cutting shears 206, a sliding groove 207, and a turntable 208. There are two of each of the following components: rotating wheel 201, T-shaped column 202, damping telescopic rod 203, sliding block 204, cutting shears 206, sliding groove 207, and turntable 208, installed symmetrically. The connection between the cutting mechanism 2, the support frame 1, and the adjustment mechanism 3 is reflected in two aspects. Firstly, the fixed shaft 205 of the cutting mechanism 2 is fixedly connected to the inner wall of the support frame 1, providing a fixed rotation center for the cutting shears 206 and ensuring the stability of the cutting position. Secondly, the rotating wheel 201 of the cutting mechanism 2 is rotatably connected to the inner wall of the sliding plate 301 of the adjustment mechanism 3. This structure allows the power input end of the cutting mechanism 2, i.e., the rotating wheel 201, to adjust its position along with the adjustment mechanism 3. Please refer to [reference needed]. Figure 5 and Figure 6 A T-shaped column 202 is fixedly connected to the inner wall of the rotating wheel 201. One end of a damping telescopic rod 203 is rotatably connected to the top of the T-shaped column 202, and the other end of the damping telescopic rod 203 is rotatably connected to a turntable 208, used to transmit the rotation of the rotating wheel 201 to the turntable 208. Simultaneously, a cutting shear 206 is rotatably connected to the outer wall of the fixed shaft 205. A sliding groove 207 is provided on the top of the cutting shear 206. A sliding block 204 is rotatably connected to the end face of the turntable 208. The sliding block 204 is rotatably connected to the inner wall of the sliding groove 207 and can slide within the sliding groove 207. In the assembled state, the sliding block 204 dynamically connects the turntable 208 and the cutting shear 206. The rotation of the sliding block 204 within the sliding groove 207 drives the cutting shears 206 to reciprocate around the fixed shaft 205 through a combination of rotation and sliding. This complete transmission and execution coordination structure of the rotating wheel 201, T-shaped column 202, damping telescopic rod 203, turntable 208, sliding block 204, and cutting shears 206 ensures the motion determinism from power input to cutting execution, realizing the automatic cutting function. The damping telescopic rod 203 has a certain axial extension capacity to compensate for the difference in motion trajectory between the top of the T-shaped column 202 and the connection point of the turntable 208, avoiding motion jamming caused by rigid connection and improving the reliability of the transmission mechanism.

[0027] As a preferred embodiment, please refer to Figure 1 and Figure 4To achieve symmetrical cutting and stable adjustment, the key components of both the cutting mechanism 2 and the adjustment mechanism 3 are preferably set to two. Specifically, the number of the rotating wheel 201, T-shaped column 202, damping telescopic rod 203, sliding block 204, cutting shears 206, sliding groove 207, turntable 208, sliding plate 301, coupling 302 and locking block 303 are all two. The two sliding plates 301 are symmetrically slidably connected to both sides of the inner wall of the support frame 1, and the two cutting shears 206 are symmetrically rotatably connected to the fixed shaft 205, forming a scissor-type cutting structure. This symmetrical arrangement helps to balance the forces on both sides during the cutting process, improve the cutting accuracy and the stability of the device operation.

[0028] As a specific implementation of the regulating mechanism 3, please refer to Figure 4 The sliding plate 301 is slidably connected to the inner wall of the support frame 1. This sliding connection ensures that the sliding plate 301 moves smoothly during the adjustment process. The relative sliding of the two sliding plates 301 is used to change the distance between the two rotating wheels 201, thereby adapting to filter bags 4 of different thicknesses.

[0029] For the locking scheme of adjustment mechanism 3, please refer to Figure 1 and Figure 4 The coupling 302 is fixedly connected to the top of the sliding plate 301, and the locking block 303 is rotatably connected to the inner wall of the coupling 302. The top of the support frame 1 is provided with multiple locking slots 304, which are arranged at equal intervals along the sliding path of the sliding plate 301. When the sliding plate 301 is adjusted to a suitable position, the operator can rotate the locking block 303 so that the protrusion of the locking block 303 engages in one of the locking slots 304. This mechanical engagement achieves precise positioning of the sliding plate 301, preventing the sliding plate 301 from shifting due to vibration or external force during the cutting process.

[0030] As a power input structure for the cutting mechanism 2, please refer to Figure 2 and Figure 5 The T-shaped column 202 is fixedly connected to the inner wall of the rotating wheel 201. The cross-sectional shape of the T-shaped column 202 matches the inner hole of the rotating wheel 201. This fixed connection ensures that the T-shaped column 202 and the rotating wheel 201 do not rotate relative to each other, so that the rotational torque generated when the filter bag 4 (not shown in the figure) rubs against the rotating wheel 201 can be transmitted to the T-shaped column 202 without loss.

[0031] As a transmission structure of the cutting mechanism 2, please refer to Figure 2 and Figure 5One end of the damping telescopic rod 203 is rotatably connected to the top of the T-shaped column 202, preferably via a ball joint or universal joint. The other end of the damping telescopic rod 203 is rotatably connected to a turntable 208. The rotation of the T-shaped column 202 is converted into the rotation of the turntable 208 by the push and pull of the damping telescopic rod 203. The telescopic characteristics of the damping telescopic rod 203 allow the radial distance between the connection point at the top of the T-shaped column 202 and the connection point at the turntable 208 to change during the motion cycle, effectively avoiding motion interference or jamming caused by rigid connecting rods.

[0032] For one method of installing the actuator of the cutting mechanism 2, please refer to [the relevant documentation]. Figure 2 The fixed shaft 205 is fixedly connected to the inner wall of the support frame 1. The axis of the fixed shaft 205 coincides with the rotation center of the cutting shears 206. This fixed connection provides a stable rotation reference for the cutting shears 206. The cutting shears 206 is rotatably connected to the outer wall of the fixed shaft 205. The rotatable connection is preferably achieved through bearings or wear-resistant bushings to ensure that the cutting shears 206 can swing flexibly around the fixed shaft 205 with low friction.

[0033] As the execution transmission end of the cutting mechanism 2, please refer to Figure 5 and Figure 6 The sliding block 204 is rotatably connected to the end face of the turntable 208 near the edge, and is also rotatably connected to the inner wall of the sliding groove 207. When the turntable 208 rotates, the sliding block 204 rotatably connected to the turntable 208 makes a circular motion in space. At the same time, the sliding block 204 rotatably connected to the sliding groove 207 slides along the axial direction of the sliding groove 207, i.e., the radial direction of the cutting shears 206. This crank-slider type compound motion precisely drives the cutting shears 206 to produce reciprocating cutting action.

[0034] Working principle: Before the need to cut the corners of the cylindrical filter bag, the operator first adjusts the filter bag 4 to accommodate different thicknesses. The operator manually moves the two sliding plates 301 that are slidably connected to the inner wall of the support frame 1. Since the two rotating wheels 201 are rotatably connected to the inner walls of the two sliding plates 301 respectively, the sliding of the two sliding plates 301 towards each other or away from each other will synchronously drive the position of the two rotating wheels 201 to change, thereby precisely adjusting the working distance between the two rotating wheels 201. When the distance is adjusted to a suitable position that can generate effective friction force on the filter bag 4, the operator rotates the locking block 303 connected to the inner wall of the coupling 302. The coupling 302 is fixedly connected to the top of the sliding plate 301. The rotation of the locking block 303 engages with one of the multiple locking slots 304 opened on the top of the support frame 1. Through the mechanical engagement of the locking block 303 and the locking slot 304, the position of the sliding plate 301 is reliably locked to prevent displacement during operation. Thus, the adjustment and locking work of the adjustment mechanism 3 is completed. After the cutting process begins, the filter bag 4 moves along a predetermined path under the action of external power transmission. Excess material from the filter bag 4 is guided between the two rotating wheels 201 and comes into frictional contact with their outer surfaces. The continuous movement of the filter bag 4 drives the two rotating wheels 201 to rotate around their own axes through friction, which is the power source for the cutting mechanism 2. Since the T-shaped column 202 is firmly fixed to the inner wall of the rotating wheel 201, the rotation of the rotating wheel 201 drives the T-shaped column 202 to rotate synchronously without delay. The rotation of the T-shaped column 202 serves as the main force input to the subsequent transmission chain. One end of the damping telescopic rod 203 is rotatably connected to the top of the T-shaped column 202, and the other end is rotatably connected to the turntable 208. When the T-shaped column 202 rotates, the damping telescopic rod 203 acts like a connecting rod, generating a pushing or pulling force on the turntable 208, forcing the turntable 208 to rotate around its fulcrum. The extension and retraction of the damping telescopic rod 203... The feature allows for compensation of the motion trajectory error between the top connection point of the T-shaped column 202 and the connection point of the turntable 208, ensuring smooth transmission. The rotation of the turntable 208 drives the sliding block 204. The sliding block 204 is simultaneously rotatably connected to the end face of the turntable 208 and rotatably connected to the inner wall of the sliding groove 207 of the cutter 206. The cutter 206 is rotatably mounted on the inner wall of the support frame 1 via the fixed shaft 205. The continuous rotation of the turntable 208 drives the sliding block 204 to make circular motion in space. The circular motion of the sliding block 204 is constrained by the sliding groove 207. The motion is decomposed into sliding along the length direction of the sliding groove 207 and driving the cutter 206 to reciprocate around the fixed shaft 205. The two cutters 206 are symmetrically arranged and perform opposite opening and closing shearing motions under the synchronous drive of the transmission mechanism, finally cutting and removing the excess material of the filter bag 4 located at the shearing point, realizing the automated cutting function using the filter bag 4 itself as power.
