Description

Technical Field

[0001] This invention relates to tire production equipment, specifically a double-linkage fiber cord splice device for correcting and retracting spliced ​​fabric. Background Technology

[0002] With the significant improvement in the automation level of domestic tire production equipment, some equipment manufacturers have launched intelligent auxiliary functions to better meet market demands and reduce the requirements for operators' skills.

[0003] The automatic correction function for misaligned joints in the fiber fabric cutting machine production line is one of many intelligent auxiliary functions. It can automatically compensate for misalignment caused by factors such as material drift and conveyor belt deviation. However, due to the limitations of the existing fabric overlapping device's impact plate structure, the correction action must be completed before the next step of fabric retraction can be carried out, which to some extent restricts the improvement of equipment efficiency.

[0004] If the curtain retraction is completed first so that the curtain is pre-pressed against the lower baffle before the correction is performed, the friction between the lower baffle and the curtain will cause the correction displacement and the actual displacement of the curtain to be inconsistent, which will ultimately affect the quality of the misaligned joint.

[0005] Faced with a conflict between efficiency and product quality, manufacturers of fiber cord fabric cutting machine production lines urgently need a solution that can eliminate the waiting time in the error correction function to ensure that the equipment's working efficiency is not affected while improving the quality of the products. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a double-linkage fiber curtain splicing device for correcting and retracting misaligned fabric, which allows the misalignment correction sequence to run synchronously or crosswise with the curtain retraction sequence.

[0007] A double-linkage fiber curtain splicing device capable of solving existing technical problems related to fabric deviation correction and retraction includes a discharge conveyor belt and a supply conveyor belt positioned before and after the overlap area along the fabric conveying direction. The overlap area is equipped with an overlap support plate, a lower baffle, an upper baffle, and an overlap pressure plate. The difference lies in:

[0008] 1. The overlapping pallet and the lower baffle are positioned front and rear between the unloading conveyor belt and the feeding conveyor belt. The overlapping pallet is mounted on the frame via left and right linear guide rails I, and the lower baffle is mounted on the frame via vertical linear guide rails II. The front end of the lower baffle 4 rests against the rear end of the overlapping pallet via a double linkage baffle. The double linkage baffle is mounted on the overlapping pallet via vertical linear guide rails III and is mounted in the left and right slots on the lower baffle via roller assemblies. The double linkage baffle can move left and right with the overlapping pallet and can also rise and fall with the lower baffle.

[0009] 2. The upper baffle is located above the overlapping support plate on the front side of the lower baffle, and the overlapping pressure plate is located above the flat part and moves forward and flat against the upper baffle.

[0010] 3. The unloading conveyor belt is installed on the front and rear left and right guide mechanisms. The unloading conveyor belt is driven by a motor. The forward or reverse rotation of the motor can unload material forward or retract material backward. The overlapping pallet is connected to the unloading conveyor belt through a clamping plate. The frame is equipped with a correction mechanism to adjust the left and right position of the unloading conveyor belt.

[0011] The beneficial effects of this invention are:

[0012] In the structure of the double-linkage fiber curtain splicing device for correcting misalignment and retraction of spliced ​​fabric, by adding a double-linkage baffle between the overlapping support plate and the lower baffle for the curtain to retract and abut against, the misalignment correction sequence and the curtain retraction sequence can run synchronously or crosswise, reducing the waiting time of ineffective sequences, improving the working efficiency of the fiber curtain cutting machine, and ensuring the quality stability of the equipment products.

[0019] The technical solution of the present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] This invention relates to a double-linkage fiber curtain splicing device for correcting and retracting fabric alignment, comprising an unloading conveyor belt 1 and a feeding conveyor belt 2 located before and after the overlapping area. The unloading conveyor belt 1 is driven by a motor, and the forward or reverse rotation of the motor can drive the unloading conveyor belt 1 to unload material forward or retract material backward. The unloading conveyor belt 1 is mounted on a frame 14 via front and rear guide mechanisms 7 (left and right directions). A correction mechanism 10, which can adjust the position of the unloading conveyor belt 1 left and right, is provided on the frame 14 between the front and rear guide mechanisms 7. The correction mechanism 10 is connected to a program control system via signal lines, such as... Figure 1 As shown.

[0021] The overlapping area is provided with a horizontal overlapping support plate 3, a horizontal lower baffle 4, a vertical upper baffle 5, and a vertical overlapping pressure plate 6.

[0022] The overlapping pallet 3 and the lower baffle 4 are positioned front and rear between the unloading conveyor belt 1 and the feeding conveyor belt 2. The front bottom of the overlapping pallet 3 is mounted on the frame 14 via a linear guide rail I 8 (left and right direction). The front end of the overlapping pallet 3 is connected to the unloading conveyor belt 1 via a clamping plate 9. The lower baffle 4 is mounted on the frame 14 via a linear guide rail II 15 (vertical) and rises and falls under the action of a cylinder I 16. The front end of the lower baffle 4 rests against the rear end of the overlapping pallet 3 via a vertical double-linkage baffle 13. The rear end of the lower baffle 4 is connected to the feeding conveyor belt 2 via a transition plate. The rising height of the lower baffle 4 is higher than that of the overlapping pallet 3, and the falling height of the lower baffle 4 is flush with that of the overlapping pallet 3. Figure 2 As shown.

[0023] The double-linkage baffle 13 is mounted on the overlapping support plate 3 via a linear guide rail Ⅲ17 (vertical). The linkage plate 13 is also mounted in a slot (left-right direction) on the wheel seat 21 via a roller assembly 18 (a combination of axle and bearing). The wheel seat 21 is mounted on the bottom of the lower baffle 4. The double-linkage baffle 13 fits against the lower baffle 4, and the top of the double-linkage baffle 13 is flush with the top of the lower baffle 4. During operation, the double-linkage baffle 13 can move horizontally left and right following the overlapping support plate 3 for correction, and can also rise and fall following the lower baffle 4 for pressing, effectively solving the problem of waiting time during the correction process. Figure 2 As shown.

[0024] The upper baffle 5 is positioned above the overlapping support plate 3 on the front side of the lower baffle 4. The upper baffle 5 is mounted on the linear guide rail IV and rises and falls under the drive of the cylinder II. The overlapping pressure plate 6 is mounted on the linear guide rail V and is located behind the upper baffle 5. The overlapping pressure plate 6 moves forward and is flush with the upper baffle 5. The overlapping pressure plate 6 is positioned downward and flush with the lower baffle 4 and the overlapping support plate 3 (the double-linkage baffle 13 + the front end of the lower baffle 4). The overlapping pressure plate 6 rises and falls under the drive of the cylinder III. Figure 1 As shown.

[0025] The overlapping area is equipped with a discharge edge sensor 11 and a supply edge sensor 12 at the front and rear. The discharge edge sensor 11 detects the edge position of the front curtain 19 on the discharge conveyor belt 1, and the supply edge sensor 12 detects the edge position of the rear curtain 20 on the supply conveyor belt 2. Each sensor feeds back the detected curtain edge position signal to the system program. The system program compares the feedback curtain edge position signal with the control mechanism 10 to automatically adjust the position of the discharge conveyor belt 1 and the overlapping support plate 3 to ensure that the edges of the front and rear curtains 19 and 20 are aligned. During the adjustment process, the double linkage baffle 13 moves left and right following the overlapping support plate 3 in the correction action. Figure 1 , Figure 2 As shown.

[0026] The steps of the scheme in this invention are as follows:

[0027] 1. During initial operation, the feeding conveyor belt 2 conveys the first piece of fabric (front fabric 19) to the overlap area. After the front fabric 19 passes the overlap area and is conveyed to the unloading conveyor belt 1, the feeding conveyor belt 2 and the unloading conveyor belt 1 operate synchronously, conveying the front fabric 19 until the tail of the fabric detaches from the double linkage baffle 13 and is placed on the overlap support plate 3. At this time, the unloading conveyor belt 1 stops conveying forward and retracts, forcing the tail of the front fabric 19 to move backward and align with the double linkage baffle 13 (at this time, the upper linkage baffle 13 is higher than the overlap support plate 3). Subsequently, cylinder II drives the upper baffle 5 to move downward and below the double linkage baffle 13. Figure 3 As shown.

[0028] 2. The feeding conveyor belt 2 continues to convey the secondary fabric (rear fabric 20) to the overlapping area. When the rear fabric 20 passes the feeding edge position sensor 12, the feeding edge position sensor 12 and the unloading edge position sensor 11 simultaneously detect the edge positions of the front and rear fabrics 19 and 20. The program automatically compares the edge position relationship between the two and controls the correction mechanism 10 to push the unloading conveyor belt 1, the overlapping support plate 3, and the double linkage baffle 13 to move together, thereby changing the position of the front fabric 19 to ensure that the edges of the front and rear fabrics 19 and 20 are aligned. Figure 4 As shown.

[0029] 3. The feeding conveyor belt 2 continues to convey the rear curtain fabric 20 until the head of the rear curtain fabric 20 abuts against the upper baffle 5, at which point the feeding conveyor belt 2 stops running. Figure 4 As shown.

[0030] 4. The overlapping pressure plate 6 is driven to descend by cylinder III. When the overlapping pressure plate 6 descends to a certain height, it will press down on the rear curtain 20, the double linkage baffle 13, and the lower baffle 4 together until the overlapping pressure plate 6 overlaps and compacts the material head of the rear curtain 20 with the material tail of the front curtain 19. Subsequently, the upper baffle 5 and the overlapping pressure plate 6 rise simultaneously and detach from the curtain. The double linkage baffle 13 returns to its original position upward along with the lower baffle 4. Figure 5 As shown.

[0031] 5. The feeding conveyor belt 2 and the unloading conveyor belt 1 operate synchronously to convey the overlapped fabric forward until the tail of the overlapped fabric leaves the double-linkage baffle 13. At this point, the unloading conveyor belt 1 stops conveying forward and retracts, forcing the tail of the overlapped fabric to align with the double-linkage baffle 13. Subsequently, the upper baffle 5 is driven by cylinder II to move downward below the double-linkage baffle 13. Figure 3 As shown.

[0032] 6. Repeat steps 2 to 5 to achieve continuous overlapping of the fiber curtain.
