Description

Technical Field

[0001] This utility model relates to the field of die-cutting, and in particular to an integrated spring core device. Background Technology

[0002] Existing technologies suffer from high energy consumption, low material changing efficiency, complex structure, and difficulty in assembly of air shaft devices. Therefore, to address these issues, this invention provides an integrated spring core device. In the die-cutting industry, the material shaft is a key piece of equipment for winding and unwinding raw materials. Material shafts are mainly divided into three types: air shafts, hand-twisted mechanical shafts, and baffle shafts. Among them, air shafts have the advantage of quick material changing, but require additional compressed air, increasing energy consumption; hand-twisted mechanical shafts are energy-saving, but their efficiency is relatively low; baffle shafts are both energy-saving and inefficient, and the operation process is cumbersome.

[0003] Currently, in the precision machining process of the die-cutting industry, the unwinding and winding mechanism generally adopts an inflatable expansion shaft, but this design has the following disadvantages: 1. The air shaft design requires additional compressed air, which increases energy consumption. Furthermore, during high-frequency inflation and deflation, factors such as ambient temperature differences can easily cause the air bladder to age and leak, affecting production. 2. Existing winding and unwinding mechanisms are complex in structure, bulky in size, difficult to assemble, and time-consuming and labor-intensive to install, making it difficult to guarantee winding and unwinding accuracy; 3. Different core sizes are required for different cutting objects, and changing the air shaft is a complicated process, which increases production costs and time; 4. The dimensions and structural design of the mechanical expansion shaft in the existing winding and unwinding mechanism are not optimized enough, which affects the service life and reliability of the mechanical expansion shaft; 5. The existing winding and unwinding mechanism lacks a fast and accurate core replacement mechanism, which makes it difficult to meet the needs of frequent replacements, affecting production efficiency and safety.

[0004] Therefore, improving material changing efficiency, reducing energy consumption, and simplifying the design of winding and unwinding mechanisms have become urgent technical problems to be solved in the current die-cutting industry. In particular, when frequent core replacement is required, how to achieve fast and accurate core replacement, improve production efficiency, reduce labor intensity, and reduce safety hazards are all urgent issues that need to be addressed. Utility Model Content

[0005] To address the aforementioned issues, this invention provides an integrated spring core device, which enables convenient, rapid, and accurate core replacement, thereby improving production efficiency, reducing labor intensity and costs, and minimizing safety hazards.

[0006] According to one aspect of the present invention, an integrated spring core device is provided, comprising an expansion core body and a control box, wherein the expansion core body is installed on the upper front side of the control box; a plurality of transverse through slots are provided on the circumference of the expansion core body, and a key bar is movably embedded in each transverse through slot through a plurality of elastic reset members, wherein the key bar can be retracted into the transverse through slot under pressure, and can be bounced up by the elastic force of the aforementioned elastic reset members to expose its upper part to the outside of the transverse through slot.

[0007] In some embodiments, a motor is housed inside the control box, and a control panel is located on the outside. The advantage is that the motor and control panel can be used to drive and control the expansion core body.

[0008] In some embodiments, a rocker arm is mounted on the front side of the expansion core body. This is advantageous because the rocker arm can be used to adjust the rotation of the expansion core body as needed.

[0009] In some embodiments, baffles are installed on both the front and rear sides of the expansion core body. The advantage of this is that the baffles can help ensure accurate material feeding.

[0010] In some embodiments, both the transverse slot and the key bar have T-shaped cross-sections. The depth of the transverse slot is greater than the thickness of the key bar, and the opening width of the transverse slot is smaller than the lower width of the key bar. This is advantageous because it allows the key bar to spring up and retract under force without detaching from the transverse slot.

[0011] In some embodiments, a limiting block is formed at the lower part of the key bar, the width of which is greater than the opening width of the transverse through slot. This is advantageous because the limiting block can be used to limit the movement of the key bar, preventing it from shifting.

[0012] In some embodiments, the rear end of the transverse through-slot extends through the rear side of the expansion core body. Advantageously, the structure of the transverse through-slot is further described.

[0013] In some embodiments, two linear bearings are formed on the key bar. The advantage is that the structure of the key bar is further described.

[0014] In some embodiments, the resilient reset element includes a reset screw and a reset spring, the reset spring being sleeved on the reset screw with its two ends respectively contacting the transverse through slot and the key strip. Its advantage lies in describing the specific structure and installation method of the resilient reset element. In some embodiments, the bottom of the key bar has multiple slots, and each of the resilient reset members extends into each of the slots. The advantage is that the specific structure of the key bar is further described. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, the device includes an expansion core body 1 and a control box 2. The expansion core body 1 is installed on the upper part of one side (the front side, and the opposite side is the rear side) of the control box 2, and multiple key bars 4 are embedded and installed on the circumference of the expansion core body 1. The control box 2 contains a motor and other related structures for driving and controlling the expansion core body 1, and has a corresponding control dial 21 on the outside, which can control the rotation of the expansion core body 1.

[0019] Preferably, a rocker arm 13 is installed on the front side of the expansion core body 1, and the rotation of the expansion core body 1 can be adjusted by using the rocker arm 13 as needed.

[0020] In a further preferred embodiment, baffles 12 are installed on both the front and rear sides of the core expansion body 1 to ensure accurate material feeding.

[0021] Multiple transverse through slots 11 are provided on the circumference of the expansion core body 1, and each key bar 4 is movably embedded in each transverse through slot 11. The cross-section of the transverse through slot and the key bar is T-shaped. The depth of the transverse through slot 11 is greater than the thickness of the key bar 4, and the opening width of the transverse through slot 11 is less than the width of the part of the key bar 4 located in it (let's call it the lower part, and the other part the upper part). Thus, the key bar 4 can be lifted up under force to expose its upper part to the outside of the transverse through slot 11, and can be retracted into the transverse through slot 11 under pressure.

[0022] Preferably, a limiting block 41 is formed at the lower part of the key bar 4. The limiting block 41 is used to limit the key bar 4 and prevent it from moving axially.

[0023] More preferably, the rear end of the transverse through-slot 11 extends through the rear side of the inflation core body 1. In addition, two linear bearings 42 are formed on the key bar 4, and the linear bearings 42 are also limited to prevent axial movement.

[0024] Each transverse through slot 11 is movably connected to the key bar 4 embedded therein via multiple elastic reset members 3. The elastic reset member 3 includes a reset screw 31 and a reset spring 32. The reset spring 32 is sleeved on the reset screw 31 and its two ends are in contact with the transverse through slot 11 and the key bar 4, respectively. When in its natural state, the reset spring 32 can extend to lift the key bar 4.

[0025] Preferably, the bottom of the key bar 4 has multiple slots 43, and each elastic reset member 3 extends into each slot 43.

[0026] When using this device, the raw material is pushed axially into the expansion core body 1 until it contacts the baffle plate 12. During the pushing process, the downward pressure of the raw material causes the key bar 4 on the expansion core body 1 to undergo axial displacement, retracting its upper part into the transverse through groove 11. At the same time, the return spring 32 is compressed to store elastic potential energy. When the raw material reaches the preset station, the return spring 32 releases the stored energy, causing the key bar 4 to spring back to its original position. Thus, the return action of the key bar 4 achieves automatic positioning and clamping of the raw material, thereby enabling material changing without external force input and shortening the material changing cycle to less than two seconds.

[0027] The integrated spring 32 winding core device of this utility model has the following beneficial effects: 1. It adopts a purely mechanical structure design. The key bar 4 slides with the expansion core body 1, and the elastic reset part 3 realizes automatic expansion and contraction. No additional compressed air is required, which significantly reduces energy consumption and avoids the problem of airbag aging and air leakage caused by environmental temperature difference during high-frequency inflation and deflation of the air shaft, thus extending its service life. 2. The winding and unwinding mechanism has a simple and compact structure, small size, and is easy to assemble and install, which greatly shortens the installation time, improves work efficiency, and ensures the accuracy of winding and unwinding. 3. By sliding the key bar 4 with the expansion core body 1, fast and accurate core replacement is achieved without replacing the entire air shaft, which reduces production costs and time and improves production efficiency; 4. The outer wall of the expansion core body 1 is provided with several through grooves 11. The two ends of the key bar 4 are fixed by limiting retaining rings and elastic reset parts 3 respectively, which effectively prevents the key bar 4 from moving axially and improves the stability and reliability of the device. 5. The baffle plate 12 is closely fitted with the core expansion body 1. Through the design of the guide groove, the raw material is accurately positioned, which improves the accuracy of winding and unwinding and reduces safety hazards.

[0028] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
