Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of diaphragm feeding equipment, in particular to a diaphragm feeding machine. Background Art
[0002] Diaphragm feeders are widely used in battery production, electronic component manufacturing, and filter material production, ensuring a continuous and stable supply of diaphragms throughout the production process. Diaphragm feeders must maintain a stable feeding speed and tension to prevent uneven tension or unstable feed speed, which can cause the diaphragms to fold, twist, or even break. Furthermore, diaphragms can become entangled during subsequent production due to equipment failure. Faulty equipment can continuously draw diaphragms from the feeder, leading to significant waste if not promptly identified.
[0003] Therefore, there is an urgent need for a diaphragm loader that can continuously and stably supply diaphragms and can quickly cut off the diaphragm supply. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a diaphragm feeder that can continuously and stably supply diaphragms and can quickly cut off the supply of diaphragms in emergency situations, thereby reducing diaphragm waste.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: a diaphragm feeding machine, comprising a hanging rack and a feeding rack, wherein the hanging rack is rotatably connected to a hanging shaft, and the feeding rack is rotatably connected to a plurality of feeding rollers arranged in pairs via a bearing seat, wherein the feeding rollers can be connected to the conveying end of the power module via a coupling, and each pair of the feeding rollers is driven by gear meshing;
[0006] The feeding rack is provided with a first horizontal plate and a second horizontal plate adjacent to the feeding roller, and a group of tensioning rollers mounted on the feeding rack are suspended above the first horizontal plate;
[0007] The bearing seat is connected to a cutting knife assembly via a servo slide and is capable of resting on the second horizontal plate.
[0008] Optionally, the moving direction of the cutting knife assembly is parallel to the central axis of the feeding roller, and the cutting knife assembly is slidably connected to the moving end of the servo slide in the vertical direction through a linear guide rail.
[0009] Optionally, the cutting knife assembly includes a knife holder mounted on the servo slide, and an annular cutting knife rotatably connected to the knife holder.
[0010] Optionally, the first horizontal plate is provided with a plurality of sinking grooves arranged in a linear array.
[0011] Optionally, the second horizontal plate is provided with a limiting plate that can be clamped on both sides of the diaphragm.
[0012] Optionally, two supporting arms are provided on the feeding rack and / or the first horizontal plate on the side facing the hanging rack, a material rack roller is provided between the two supporting arms, and the material rack roller and the tensioning roller are staggered in height.
[0013] Optionally, the hanging shaft is a damping roller.
[0014] Optionally, the power module is a servo motor.
[0015] Compared with the prior art, the present invention achieves the following beneficial effects: by placing a rolled diaphragm on a hanging shaft, the diaphragm is then passed sequentially through the gap between the tensioning roller and the first horizontal plate, and then through the gap between a pair of feed rollers, and then introduced into subsequent equipment. The servo motor is then activated in conjunction with the subsequent equipment, and the feed rollers are driven to rotate via a power module, thereby conveying the diaphragm toward the subsequent equipment. During the diaphragm conveying process, the servo slide can quickly actuate the cutting blade assembly to cut the diaphragm on the second horizontal plate, preventing the diaphragm from being further fed into the subsequent equipment.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

Unless otherwise clearly specified and defined, the terms "set", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0022] like Figure 1-Figure 2 As shown, a diaphragm loading machine includes a hanging rack 1 and a feeding rack 2. The hanging rack 1 is rotatably connected to a hanging shaft 101, and the hanging shaft 101 is a damping roller in the prior art. The rolled diaphragm can be sleeved on the hanging shaft 101; the feeding rack 2 is rotatably connected to a plurality of feeding rollers 4 arranged in pairs through a bearing seat 3, and a gap is reserved between each pair of feeding rollers 4 for passing the diaphragm; the feeding rollers 4 can be connected to the conveying end of the power module 5 through a coupling, and each pair of feeding rollers 4 is driven by gear meshing. The number of gear teeth and module on each feeding roller 4 are equal, that is, when one of the feeding rollers 4 is driven to rotate by the power module 5, the corresponding feeding roller 4 and the feeding roller 4 can rotate in the opposite direction at the same speed. When the diaphragm passes through the gap between a pair of feeding rollers 4, the surface of the feeding roller 4 can be pressed down on the diaphragm, flattening the diaphragm while also pushing the diaphragm.
[0023] The feeding rack 2 is provided with a first horizontal plate 6 and a second horizontal plate 7 adjacent to the feeding roller 4. The diaphragm delivered by the hanging roller can be laid on the first horizontal plate 6 and the second horizontal plate 7. The surfaces of the first horizontal plate 6 and the second horizontal plate 7 are smooth and without marks, and will not scratch the diaphragm. A set of tensioning rollers 8 installed on the feeding rack 2 is suspended above the first horizontal plate 6.
[0024] The tensioning roller 8 described above is conventional technology. It can be slidably mounted on the feed frame 2 via a support, bracket, or track, and can be fixed at any position on the feed frame 2 using mechanical devices such as adjusting bolts. To increase the diaphragm tension, the tensioning roller 8 can be simultaneously adjusted toward the material conveying path, increasing the pressure exerted by the tensioning roller 8 on the diaphragm and thereby increasing the material tension. Conversely, to decrease the diaphragm tension, the tensioning roller 8 can be adjusted away from the material conveying path to reduce the pressure exerted by the tensioning roller 8 on the diaphragm, thereby lowering the material tension.
[0025] As mentioned above, the bearing seat 3 is connected to a cutting knife assembly that can rest against the second horizontal plate 7 through the servo slide 9. The servo slide 9 can use a programmable logic controller (PLC), a motion controller, or a dedicated servo driver in the prior art as a core controller. These controllers can receive external input command signals and generate control signals according to preset programs and algorithms, thereby accurately controlling the movement of the servo slide 9. The servo slide 9 in this technical solution can be connected to the equipment used in subsequent production through the PLC. When the equipment fails, the command signal output by the equipment can control the servo slide 9 to move quickly, thereby cutting off the diaphragm on the second horizontal plate 7 and preventing the diaphragm from being further input into subsequent equipment.
[0026] Furthermore, the power module 5 is a servo motor in the prior art. The servo motor can coordinate control signals with the servo slide 9 through devices such as a programmable logic controller (PLC), a motion controller or a dedicated servo driver in the prior art, so that the servo motor and the servo slide 9 can coordinate actions during operation to achieve better working results.
[0027] Further, such as Figure 1 As shown, the moving direction of the cutting knife assembly is parallel to the central axis of the feed roller 4, so as to reduce the time for the cutting knife assembly to cut the diaphragm at the same speed; the moving direction of the cutting knife assembly is parallel to the central axis of the feed roller 4, and the cutting knife assembly is connected to the moving end on the servo slide 9 by a linear guide 10 in a vertical direction. Specifically, the linear guide 10 includes a guide rail and a slider. The cutting knife assembly is installed on the slider. The slider is threaded with bolts and other fasteners that can abut against the guide rail, so that the slider can be fixed at any position on the guide rail within the stroke, thereby facilitating the adjustment of the distance between the cutting knife assembly and the second horizontal plate 7, that is, facilitating the adjustment of the cutting depth of the diaphragm.
[0028] By adjusting the cutting depth of the diaphragm by the cutting blade assembly, the diaphragm is not completely cut, which enables the diaphragm loader of this technical solution to be adapted to certain special process requirements, thereby realizing the diaphragm loader's functional diversification. For example, if the diaphragm requires a specific coating treatment in one stage and then a heat pressing or stretching operation in the next stage, incompletely cutting the diaphragm can facilitate its transfer from one stage to the next to ensure continuity and stability between the stages, while also avoiding deviations during repositioning and transfer.
[0029] The above, such as Figure 2 As shown, the cutting knife assembly includes a knife seat 11 mounted on the servo slide 9, and an annular cutting knife 12 rotatably connected to the knife seat 11. The rotating annular cutting knife 12 can realize continuous cutting action. Compared with the traditional linear reciprocating cutting method, it reduces the pause and acceleration time in the cutting process, makes the cutting process smoother, and greatly improves the cutting efficiency. At the same time, since the contact between the blade on the annular cutting knife 12 and the diaphragm is continuous and uniform during the rotation of the annular cutting knife 12, the rotating annular cutting knife 12 can provide a more stable cutting force. This uniform cutting force can ensure that the diaphragm will not have local uneven force during the cutting process, thereby effectively improving the quality of diaphragm cutting.
[0030] The above, such as Figure 1 As shown, the first horizontal plate 6 is provided with a plurality of sinking grooves 601 arranged in a linear array. There is a height difference between the surface of the first horizontal plate 6 in contact with the diaphragm and the bottom of the sinking groove 601, which can effectively prevent the diaphragm from being adsorbed on the first horizontal plate 6.
[0031] The above, such as Figure 1 As shown, the second horizontal plate 7 is provided with a limit plate 13 that can be clamped on both sides of the diaphragm to prevent wrinkling of the diaphragm edges. At the same time, the limit plate 13 can be fixed to any position on the second horizontal plate 7 by fasteners such as bolts, thereby effectively limiting and guiding the conveying direction of the diaphragm.
[0032] Further, such as Figure 1 As shown, two support arms 14 are provided on the feeding rack 2 and / or the first horizontal plate 6 on the side facing the hanging rack 1, and a material rack roller 15 is provided between the two support arms 14. The material rack roller 15 and the tensioning roller 8 are staggered in height. As the rolled diaphragm on the hanging shaft 101 is continuously output, the diameter of the rolled diaphragm will continue to decrease. The material rack roller 15 can be supported under the diaphragm, thereby avoiding the diaphragm from directly overlapping the edge of the first horizontal plate 6, preventing the diaphragm from being scratched.
[0033] Working principle: First, the rolled diaphragm is placed on the hanging shaft 101, and then the diaphragm is passed through the gap between the tensioning roller 8 and the first horizontal plate 6, and the gap between a pair of feed rollers 4 in sequence, and then the diaphragm is introduced into the subsequent equipment. Then, the servo motor is started in conjunction with the subsequent equipment, and the feed roller 4 is driven by the servo motor to rotate, thereby conveying the diaphragm toward the subsequent equipment. In the process of conveying the diaphragm, if the equipment fails, the command signal output by the equipment can control the servo slide 9 to move quickly, thereby driving the annular cutter 12 to cut the diaphragm on the second horizontal plate 7, preventing the diaphragm from being further input into the subsequent equipment. Alternatively, by adjusting the distance between the annular cutter 12 and the second horizontal plate 7, the annular cutter 12 can be driven by the servo slide 9 to continuously and incompletely cut the diaphragm, thereby meeting the process requirements.
[0034] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
