Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a compact backfeeder. Background Art

[0002] As an advanced feeding module, feeder plays an important role in the field of automation equipment. It is widely used due to its high efficiency, flexibility, easy installation, high stability and excellent discharge accuracy. There are many types of feeders on the market with different specifications to meet different production needs. However, a common problem in the existing pull-out feeder design is that its lateral size is large, especially for the pull-out feeder with a coil width of 80mm, the equipment width usually reaches 140-150mm, which not only limits its application in space-constrained environments, but also poses a challenge to the overall equipment layout and the compactness of the production line.

[0003] The shortcomings of the existing technology are mainly reflected in two aspects:

[0004] 1. The overall width of the pull-back feeder is too large, which affects its deployment and application flexibility in limited space;

[0005] 2. Due to the limitations of the equipment structure layout, the optimization of the withdrawal distance is restricted, which affects the feeding efficiency and the overall effectiveness of the system.

[0006] Therefore, the prior art has deficiencies and needs further improvement. Utility Model Content

[0007] In view of the problems existing in the prior art, the utility model provides a compact rearward feeder.

[0008] To achieve the above purpose, the specific scheme of the utility model is as follows:

[0009] The utility model provides a compact retracting feeder, comprising:

[0010] A material unwinding component, used for storing coiled materials;

[0011] The back-retracting stripping knife assembly is used to strip the material on the coil from the base material;

[0012] A material pulling component, used for pulling the bottom material of the coil forward;

[0013] A material collecting component, used for collecting the bottom material after the material is stripped;

[0014] The unloading assembly includes an unloading wheel for storing the coiled material;

[0015] A screw rod and slide rail assembly is also provided below the back-moving stripping knife assembly to drive the back-moving stripping knife assembly to move back and forth;

[0016] The screw rod and slide rail assembly comprises: a first motor, a screw rod, a slider, and a slide rail;

[0017] The back-retracting stripping knife assembly is installed on the slide block;

[0018] The slider is slidably mounted on the slide rail, and the slider is also threadedly mounted on the screw rod, and the rotating shaft of the first motor is connected to the screw rod to drive the screw rod to rotate;

[0019] The rotation of the first motor drives the screw rod to rotate forward and reversely, thereby driving the slider to move back and forth on the slide rail, and then driving the back-moving stripping knife assembly to move back and forth, thereby adjusting the distance between the discharge assembly and the back-moving stripping knife assembly.

[0020] Furthermore, the feeder also includes a material receiving platform assembly, which is arranged at the tail of the stripping knife assembly and is used to receive the material stripped from the stripping knife assembly;

[0021] The material receiving platform assembly is provided with a plurality of first through holes penetrating from top to bottom, and a first sensor is provided below the first through hole for sensing whether the material exists, so as to judge whether the material stripping is successful.

[0022] Furthermore, an adsorption and pressing component is provided between the material discharge component and the back-retracting stripping knife component;

[0023] The adsorption and pressing component comprises an adsorption plate;

[0024] The adsorption plate is provided with a plurality of second through holes penetrating vertically, and a first suction tube is provided below the second through holes for generating an adsorption force through suction to allow the material strip to adhere to the adsorption plate.

[0025] Furthermore, a material guide roller is provided between the material discharge component and the material adsorption and pressing component, and the material belt passes through the material guide roller and enters the material pressing and adsorption component after coming out of the material discharge component.

[0026] Furthermore, the material receiving assembly includes: a third motor and a material receiving roller;

[0027] The end of the bottom material of the coil is fixed on the receiving roller, and the third motor drives the receiving roller to rotate through the first belt to roll the bottom material after the material is stripped onto the receiving roller.

[0028] Furthermore, the material pulling assembly includes: a second motor, a first roller, a second roller, and a third roller;

[0029] The first roller is arranged below the back-retracting stripping knife assembly, the second roller is arranged below the first roller, the third roller is arranged below the second roller, the second roller and the third roller abut against each other to clamp the material strip of the base material;

[0030] The second motor is installed beside the second roller shaft, a first gear plate is arranged on the rotating shaft of the second motor, a second gear plate is arranged on the second roller shaft, and the first gear plate and the second gear plate are meshed with each other;

[0031] The material belt of the base material of the coil enters from the left side of the first roller to the right side of the second roller, and then passes between the second roller and the third roller to reach the material receiving assembly. The second motor drives the first gear plate to rotate and then drives the second gear plate to rotate, and then drives the second roller to rotate. The second roller and the third roller clamp the base material and move forward.

[0032] Further, the third roller is mounted on the first bracket, and the first bracket is mounted on the first rotating shaft;

[0033] The third roller is also provided with a handle for driving the third roller to rotate around the first rotating shaft;

[0034] When the handle rotates to drive the third roller away from the second roller, the clamping force is not applied to the base material. When the handle rotates to drive the third roller to abut against the second roller, the clamped base material moves forward.

[0035] Furthermore, a fourth roller is provided below the retracted stripping knife assembly;

[0036] The bottom material after stripping the material passes through the fourth roller and then reaches the first roller.

[0037] The technical solution of the utility model has the following beneficial effects:

[0038] 1. Space optimization and enhanced compactness: Through careful design, the overall width of this feeder can be controlled within 120mm even for the working condition of processing coil width of 80mm. Compared with the conventional pull-back feeder which is usually 140-150mm wide, it greatly reduces the equipment footprint and improves the application flexibility of the equipment in limited space. It is particularly suitable for the layout of automated production lines with tight space.

[0039] 2. Improve operational efficiency and flexibility: The front design of the feeding part not only makes rational use of the internal space of the equipment, but also maximizes the withdrawal distance, which can reach 150mm. This not only optimizes the material stripping and conveying process, but also improves the overall response speed and operating range of the feeding system, ensuring efficient and continuous feeding operations.

[0089] Advantages of the utility model:

[0090] 1. Compact backfeeder, suitable for coil width 80mm, the backfeeder width can be within 120mm;

[0091] 2. The feeding part is placed forward, and the maximum withdrawal distance is 150mm.

[0092] The principle of this utility model is as follows:

[0093] Startup and unwinding: After the equipment is started, the unwinding wheel 1 in the unwinding assembly starts to rotate to carry and gradually unwind the coil. The coil falls naturally under the action of gravity and is guided to the subsequent processing area by the guide roller 12.

[0094] Adsorption and pressing: After the coil passes through the unloading assembly, it enters the adsorption and pressing assembly, where the adsorption plate 9 uses the negative pressure adsorption force generated by the first suction tube 11 to ensure that the material strip is flatly attached to the adsorption plate 9, providing stable material strip support for the subsequent peeling operation.

[0095] Precise retraction and stripping: The retraction of the stripping blade assembly 7 is driven by the screw rod 3 and the slide rail 5 assembly, and the first motor 2 controls the screw rod 3 to rotate forward and reverse, driving the slider 4 and the stripping blade assembly installed thereon to move back and forth along the slide rail 5. This action accurately adjusts the distance between the unwinding assembly and realizes the precise stripping of the material on the coil from the base material.

[0096] Material detection and receiving: The stripped material falls directly onto the material receiving platform assembly 6. The first sensor 8 on the assembly determines whether the stripping process is successfully completed by monitoring whether there is material under the first through hole, thereby ensuring the reliability of the process and the continuity of material processing.

[0097] Bottom material traction and collection: After the material is stripped, the bottom material continues to move forward under the action of the material pulling assembly. The material pulling assembly includes multiple rollers, wherein the second motor 15 drives the second and third rollers 18 to rotate through a gear transmission system, and the two rollers clamp the bottom material to each other and provide forward traction. The rotation of the handle 23 controls the distance between the third roller 18 and the second roller 17 to achieve the clamping or release of the bottom material. The bottom material is finally guided by the fourth roller 24 to reach the material receiving assembly.

[0098] Bottom material recovery: driven by the third motor 13, the receiving roller 14 in the receiving assembly rotates, and through the linkage action of the first belt, the bottom material is wound and recovered to complete the entire feeding cycle.

[0099] Through the above process, this compact retraction feeder achieves efficient and precise stripping of coiled materials and continuous recovery of base materials, optimizes space utilization (the equipment width is only 120mm), and can achieve a retraction distance of up to 150mm in a limited space, greatly improving the feeding flexibility and efficiency of automated equipment.

[0100] The above description is only a preferred embodiment of the present invention, and does not limit the scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the concept of the present invention, or directly / indirectly applied in other related technical fields are included in the protection scope of the present invention.
