Description

Technical Field

[0001] This utility model relates to the field of feeders, and in particular to a feeder with a modular structure. Background Technology

[0002] A feeder is a mechanical device used for the continuous and controlled conveying of bulk materials. Common types include rotary feeders, automatic feeders, and smart label feeders. Its core structure typically consists of a rotor, housing, drive unit, and sealing system, which transports material from the inlet to the outlet through rotation or mechanical motion. These devices are widely used in industries such as chemical, food, pharmaceutical, and electronics manufacturing. They are suitable for pneumatic conveying, packaging feeding, and automated production lines, offering advantages such as stable flow rate, high adjustability, and adaptability to various material characteristics.

[0003] Existing feeders mostly use a fixed frame and rigid connection structure for the loading end, and realize the material roll conveying function through the guide rail mechanism. Due to the limited space in the factory, the equipment needs to be adapted to different factory layouts and dynamic production requirements. When the customer's application scenario changes, the existing installation method of the feeding module cannot be quickly adjusted in position, making it difficult to meet the compatibility requirements of multiple scenarios. Furthermore, different products may require different loading heights, and the fixed feeding end of the feeder is also difficult to adapt to different loading and unloading requirements.

[0004] Meanwhile, existing feeders are designed as a single unit for feeding materials without cover strips. When manufacturers need to feed materials with cover strips, they need to return the feeders to the factory for modification and installation of a cover strip receiving mechanism, which is time-consuming and labor-intensive. On the other hand, for manufacturers who do not need to feed materials with cover strips, directly purchasing and installing feeders with cover strip receiving mechanisms would greatly increase production costs and would be redundant. Utility Model Content

[0005] The main objective of this invention is to propose a modular feeder to solve existing technical problems.

[0006] To achieve the above objectives, this utility model proposes a modular feeder, including a frame. Along the feeding direction, the frame is sequentially provided with a loading shaft, a rotating arm, a first guide shaft, a guide plate, a pressure plate, and a support plate. One end of the rotating arm is rotatably connected to the frame, and the other end is fixedly connected to the loading shaft. A fixing mechanism for fixing the upper part of the guide plate is provided above the guide plate. A first take-up mechanism is provided at the lower end of the frame. During material roll installation, the material roll is installed on the loading shaft, and the material sheet is pulled out and inserted below the first guide shaft, then pulled up to the upper part of the guide plate. It is then peeled off from above, passing around the pressure plate and approaching the support plate. After peeling, the substrate is pulled down to the first take-up mechanism and fixed to its output end. Above the first guide shaft, the frame also has a cover strip take-up module for peeling off the cover strip of the material sheet. The cover strip take-up module is detachably connected to the frame.

[0007] This invention allows the loading shaft to be set to an adjustable position through the rotating connection between the rotating arm and the frame, enabling the feeder to adapt to different space requirements. The loading shaft can be adjusted to a suitable position according to appropriate loading and unloading needs. The cover tape receiving module can peel off and collect the cover tape covering the product, exposing the product for peeling. The cover tape receiving module can be selected and added according to the user's product needs, and is easy to install without the need for factory modification.

[0008] Preferably, the cover tape receiving module includes a fixed plate and a second guide shaft, a third guide shaft, and a second receiving mechanism, all fixed to the fixed plate. The third guide shaft is installed diagonally above the left side of the second guide shaft, and the second receiving mechanism is located diagonally above the right side of the third guide shaft. When the cover tape needs to be peeled off, the material passes under the first guide shaft and then tears the cover tape so that the cover tape crosses the second guide shaft. Then, it wraps around from the lower end of the third guide shaft to the upper end and is pulled to the second receiving mechanism for fixed connection.

[0009] Preferably, the fixing plate is provided with a vertically downward guide rail, and a slider is connected to one end of the second guide shaft, the slider being slidably connected to the guide rail.

[0010] This invention uses a movable second guide shaft to adjust the tension requirements of different materials, so as to better collect waste materials.

[0011] Preferably, the second receiving mechanism includes a receiving shaft and a transmission assembly, one end of the receiving shaft is connected to the output end of the transmission assembly, and the receiving shaft is rotatably connected to the fixed plate.

[0012] Preferably, the take-up shaft is provided with a fixing buckle, the fixing block is U-shaped, one end of the outer periphery of the take-up shaft is provided with a fastening groove for fixing the cover strap, and the end face of the take-up shaft is provided with a fixing groove for fixing the fixing buckle. The two ends of the U-shaped fixing buckle are respectively inserted into the fastening groove and the fixing groove and slidably connected.

[0013] Preferably, the fixing mechanism includes a pressure plate and a driving assembly, wherein the pressure plate is fixedly connected to the output end of the driving assembly.

[0014] Preferably, the lower end face of the first guide shaft is lower than the upper end face of the guide plate.

[0015] Preferably, the guide plate has a smooth guide portion at one end near the first guide shaft.

[0016] Preferably, the rotating arm has a plurality of adjustment holes at the end away from the loading shaft, the adjustment holes being evenly distributed along the rotating shaft connecting the rotating arm and the frame, and the frame has a fixing hole at the end near the rotating arm, in which a fixing pin for fixing the angle of the rotating arm is installed.

[0017] The technical solution of this utility model has the following beneficial effects: By modularizing the cover tape receiving mechanism, customers can choose according to their needs. If only two layers of material need to be fed, a feeder without a cover tape receiving module can be purchased directly, saving costs. If materials with cover tape are needed in the production process, a cover tape receiving module can be purchased and installed online without returning to the factory for modification, saving time and effort. The cover tape receiving module can peel and collect the cover tape from the product, thus exposing the product for peeling. The rotating arm is rotatably connected to the frame, allowing the material roll installed on the loading shaft to be adjusted relative to the frame. The rotating arm can be adjusted to a suitable position according to different space requirements or loading / unloading requirements. When the customer's application scenario changes, the feeding shaft can be quickly adjusted to meet the compatibility requirements of multiple scenarios and adapt to various application scenarios.

[0029] This utility model proposes a modular feeder.

[0030] like Figure 1 As shown in one embodiment of this utility model, the modular feeder includes a frame 1. The frame 1 is provided with a loading shaft 2, a rotating arm 3, a first guide shaft 4, a guide plate 5, a pressure plate 6, and a supporting plate 7 in sequence along the feeding direction. The rotating arm 3, the first guide shaft 4, the guide plate 5, the pressure plate 6, and the supporting plate 7 are arranged on the same plane, or they can be arranged with a certain height difference. One end of the rotating arm 3 is rotatably connected to the frame 1, and the other end of the rotating arm 3 is fixedly connected to the loading shaft 2. A fixing mechanism 8 is provided above the guide plate 5 for fixing the material sheet at the upper end of the guide plate 5. A first receiving mechanism 10 is provided at the lower end of the frame 1. The pressure plate 6 and the supporting plate 7 are arranged close to each other to facilitate the receiving of the material after the material sheet is peeled off. When the material roll is installed, the material roll is installed on the loading shaft 2 and the material sheet is pulled out and inserted below the first guide shaft 4 and then pulled up to the upper end of the guide plate 5. Then, it is peeled off from above, passing around the pressure plate 6 and approaching the supporting plate 7. After peeling, the substrate is pulled down to the first receiving mechanism 10 and fixed to its output end.

[0031] In this embodiment, the rotating arm 3 is rotatably connected to the frame 1, so that the material roll installed on the loading shaft 2 can be adjusted in position relative to the frame 1. Thus, the rotating arm 3 can be adjusted to a suitable position according to different space requirements or loading and unloading requirements to adapt to various application scenarios.

[0032] The fixing mechanism 8 may include a pressure plate 81 and a motor. The pressure plate 81 can be controlled to move in extension and retraction relative to the guide plate 5 by a screw, or the pressure plate 81 can be controlled to move by a cylinder. The details are omitted here. The first receiving mechanism 10 may include a receiving rod and a motor. The receiving rod is driven to rotate by the motor to receive the material. Alternatively, multiple auxiliary rollers can be added to guide the material pieces so that the material is received more neatly.

[0033] Furthermore, the feeder includes a frame 1, with a loading shaft 2, a rotating arm 3, a first guide shaft 4, a guide plate 5, a pressure plate 6, a supporting plate 7, and a first take-up mechanism 10 arranged sequentially along the feeding direction. One end of the rotating arm 3 is hinged to the frame 1 via a bearing, and the other end is fixed to the loading shaft 2. The rotating arm 3 can rotate around the hinge point to adjust the height and tilt angle of the loading shaft 2. The fixing mechanism 8 is located above the guide plate 5 and includes a pressure plate 81 and a cylinder. The pressure plate 81 is driven by the cylinder to press down, fixing the position of the material sheet on the guide plate 5 and preventing the material sheet from being pulled when taking material from the supporting plate 7, thus preventing deviation in the position of the material sheet. In the feeding path, the material roll is installed on the loading shaft 2. The material sheet passes under the first guide shaft 4, is pulled up to the guide plate 5, passes the front end of the pressure plate 6, and is peeled off at the supporting plate 7. The substrate is then wound and recycled by the first take-up mechanism 10. The material roll is placed on the loading shaft 2, and the rotating arm 3 is adjusted to a suitable angle (such as 30°) to facilitate quick loading and unloading and adapt to suitable space requirements.

[0034] The frame 1 is welded from aluminum alloy profiles and has an anti-rust coating. The loading shaft 2 carries the material roll, and its diameter can be adjusted according to the inner diameter of the material roll, for example, by using a detachable bushing to adapt to different specifications of material rolls. One end of the rotating arm 3 is hinged to the frame 1 via a rotating shaft, and the other end is welded and fixed to the loading shaft 2. The rotating arm 3 can rotate 0°-90° around the hinge point to adjust the material roll discharge angle. The surface of the first guide shaft 4 is covered with a polyurethane rubber layer to reduce friction. Its installation height is lower than that of the subsequent guide plate 5, forming a height difference to guide the material sheet to transition naturally. The guide plate 5 is made of stainless steel plate bent into shape, and its end near the first guide shaft 4 is machined into a 30° bevel to ensure that the material sheet does not get stuck when turning. The pressure plate 6 is fixed to the frame 1 by bolts. The pressure plate 6 has multiple suction holes for fixing the material sheet. The distance between the end of the pressure plate 6 and the support plate 7 is adjustable for peeling the substrate off the material sheet. The surface of the support plate 7 has anti-slip texture to receive the finished product after peeling. One end near the pressure plate 6 has a suction hole for fixing the product. In the feeding process, after the material roll is installed on the loading shaft 2, the operator pulls out the material sheet, passes it under the first guide shaft 4, and then pulls it up to the surface of the guide plate 5. The material sheet moves along the guide plate 5 to the end of the pressure plate 6. At this time, the substrate (such as release paper) separates from the material sheet. The substrate hangs down to the first receiving mechanism 10 under the frame 1 and is connected to it (for example, a receiving roller driven by a motor). The material sheet continues to be conveyed to the receiving plate 7.

[0035] Preferably, such as Figure 2As shown, the frame 1 is also provided with a cover strip receiving module 9 above the first guide shaft 4 for peeling off the cover strip from the top of the product. The cover strip receiving module 9 is detachably connected to the frame 1. The detachable cover strip receiving module 9 can be selectively installed according to the material. For example, if there is a cover strip on the upper surface of some products, the cover strip receiving module 9 is needed to peel off the cover strip, thereby realizing the feeding of various types of materials. The cover strip receiving module 9 can be a combination of a receiving shaft 93 and a motor. The receiving shaft 93 is rotated and the material is received by controlling the motor. Alternatively, multiple auxiliary rollers can be added to guide the cover strip and facilitate the receiving shaft 93 to receive the material. The position of the auxiliary rollers is not limited here, as long as they can play a guiding role.

[0036] Preferably, such as Figure 2 As shown, the cover tape receiving module 9 includes a fixed plate 94 and a second guide shaft 91, a third guide shaft 92, and a second receiving mechanism, all fixed to the fixed plate 94. The third guide shaft 92 is installed diagonally above the left side of the second guide shaft 91, and the second receiving mechanism is located diagonally above the right side of the third guide shaft 92. When the cover tape needs to be peeled off, the material passes under the first guide shaft 4 and then tears the cover tape so that the cover tape crosses the second guide shaft 91. Then, it wraps around from the lower end of the third guide shaft 92 to the upper end and is pulled to the second receiving mechanism for fixed connection.

[0037] Preferably, the fixing plate 94 is provided with a vertically downward guide rail 96, and a slider 95 is connected to one end of the second guide shaft 91. The slider 95 is slidably connected to the guide rail 96. Alternatively, the height of the second guide shaft 91 can be adjusted to adjust the tightness of the cover strap to meet the tension requirements of different materials.

[0038] Preferably, the second receiving mechanism includes a receiving shaft 93 and a transmission assembly 97. One end of the receiving shaft 93 is connected to the output end of the transmission assembly 97, and the receiving shaft 93 is rotatably connected to the fixed plate 94. The receiving shaft 93 is driven to rotate and receive materials by the driving assembly 82.

[0039] Furthermore, the frame 1 has a pre-drilled mounting hole above the first guide shaft 4, and the cover tape take-up module 9 is connected to the frame 1 via quick-release bolts. The cover tape take-up module 9 includes: a fixed plate 94 with positioning pins on both sides that match the frame 1 to ensure installation accuracy; a second guide shaft 91 with a chrome-plated surface, which is slidably connected to the guide rail 96 of the fixed plate 94 via a slider 95, and its height can be manually adjusted; a third guide shaft 92, installed at a 45° position to the upper left of the second guide shaft 91, used to change the cover tape path; and a second take-up mechanism including a take-up shaft 93 and a geared motor, with the take-up shaft 93 connected to the output shaft of the geared motor via a coupling. In the cover tape peeling process, when the sheet needs to be peeled off, the operator tears the cover tape from the edge of the sheet, manually wraps it around the upper surface of the second guide shaft 91, then folds it back to the upper surface via the lower surface of the third guide shaft 92, and finally winds it onto the take-up shaft 93. By adjusting the height of the second guide shaft 91, the peeling tension requirements of cover tapes of different thicknesses can be accommodated.

[0040] Preferably, such as Figure 3 As shown, the take-up shaft 93 is equipped with a fixing buckle 933 and a U-shaped fixing block. One end of the outer periphery of the take-up shaft 93 is provided with a fastening groove 931 for fixing the cover strap, and the end face of the take-up shaft 93 is provided with a fixing groove 932 for fixing the fixing buckle 933. The two ends of the U-shaped fixing buckle 933 are respectively inserted into the fastening groove 931 and the fixing groove 932 and slidably connected. When fixing is required, the fixing buckle 933 is pulled out, the material is placed on the fastening groove 931, and then the fixing buckle 933 is inserted. If it is not tight enough, the material can be wrapped around the take-up shaft 93 a few more times before inserting the fixing buckle 933.

[0041] Furthermore, the end of the take-up shaft 93 is provided with a U-shaped fixing buckle 933, and its inner wall is provided with a rubber anti-slip layer. When installing the cover strap, insert the end of the cover strap into the fastening groove 931 of the take-up shaft 93, insert the two ends of the U-shaped fixing buckle 933 into the fastening groove 931 and the fixing groove 932 respectively, rotate the fixing buckle 933 to the locking position, and use the friction of the rubber layer to fix the cover strap.

[0042] Optionally, the retaining clip 933 can be replaced with a spring clip or a magnetic clamp to accommodate the fixing needs of different material cap straps.

[0043] Preferably, such as Figure 4 As shown, the fixing mechanism 8 includes a pressure plate 81 and a drive assembly 82. The pressure plate 81 is fixedly connected to the output end of the drive assembly 82. The drive assembly 82 can be a combination of a motor and a lead screw, or it can be driven by a cylinder or a hydraulic cylinder, which will not be described in detail here. The pressure plate 81 can press the material sheet onto the guide plate 5 to fix the material sheet, preventing the substrate from being pulled when the material on the support plate 7 is removed, thus preventing the material sheet from shifting.

[0044] Preferably, the lower end face of the first guide shaft 4 is set lower than the upper end face of the guide plate 5.

[0045] Furthermore, the vertical distance between the lower end face of the first guide shaft 4 and the upper end face of the guide plate 5 is 30mm, forming a natural drop. The smooth guide part 51 of the guide plate 5 adopts an R5 arc transition (alternative: 45° slope). When the sheet transitions from the first guide shaft 4 to the guide plate 5, the bending radius is greater than the minimum allowable bending radius of the sheet, thus avoiding material damage.

[0046] Preferably, the guide plate 5 is provided with a smooth guide portion 51 at one end near the first guide shaft 4. It can be obliquely cut or bent into an arc shape. The smooth guide portion 51 can prevent the material sheet from getting stuck.

[0047] Preferably, such as Figure 5 As shown, the rotating arm 3 is provided with several adjustment holes 31 at the end away from the loading shaft 2. The adjustment holes 31 are evenly distributed along the rotating shaft that connects the rotating arm 3 to the frame 1. The frame 1 is provided with a fixing hole 11 at the end near the rotating arm 3. A fixing pin 12 for fixing the angle of the rotating arm 3 is installed in the fixing hole 11. When the rotating arm 3 is adjusted to an appropriate position, the fixing pin 12 is inserted into the corresponding adjustment hole 31 for fixing, which is convenient and quick.

[0048] Furthermore, the end of the rotating arm 3 away from the loading shaft 2 is provided with 6 adjustment holes 31, and the spacing between adjacent holes corresponds to an adjustment step of 15° for the angle of the loading shaft 2. During operation, the rotating arm 3 is rotated to the target angle, and the fixing pin 12 is inserted into the corresponding adjustment hole 31 and the fixing hole 11 of the frame 1 to lock the angle.

[0049] Optionally, the adjustment hole 31 can be replaced with a rack and pinion structure, which allows for stepless adjustment of the angle of the rotating arm 3 via gears, with an accuracy of ±1°.

[0050] Specifically, the working principle and usage process of this utility model are as follows: By modularizing the cover tape receiving mechanism, customers can choose to purchase according to their needs. If only two layers of material need to be supplied, a feeder without a cover tape receiving module can be purchased directly, saving costs by eliminating the need to install the cover tape receiving mechanism module. If materials with cover tape are needed during production, a cover tape receiving module can be purchased and installed online without the need for factory modification, saving time and effort. The cover tape receiving module can peel off and collect the cover tape on the product, thus exposing the product for peeling. The rotating arm is rotatably connected to the frame, allowing the material roll installed on the loading shaft to be adjusted relative to the frame. This allows the rotating arm to be adjusted to a suitable position according to different space requirements or loading / unloading requirements to adapt to various application scenarios.

[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
