Description

TECHNICAL FIELD

[0001] The present application relates to a fiber cord cutting production line device, in particular to a partition plate type fiber cord joint device and method. BACKGROUND

[0002] At present, the advanced fiber cord cutting production lines at home and abroad all adopt the structure of multiple narrow conveying belts combined with strip-shaped lifting material receiving tables to realize the material receiving and lapping of fiber cords. The technical features of this structure are complex mechanism, high production and manufacturing cost of equipment, great difficulty in equipment assembly and debugging, and high skill level requirement for equipment assembly, debugging and maintenance personnel.

[0003] Due to the structural characteristics of multiple narrow conveying belts and strip-shaped lifting material receiving tables, the cord of some width specifications is prone to sagging in the gap between the conveying belts or lifting tables, and the conveying belts and lifting tables are prone to material jamming. At the same time, the joint step sequence occupies a long time in the whole cutting work cycle, and the cutting step sequence and the clamping and feeding step sequence exist the phenomenon of waiting for the completion of the joint step sequence. Shortening the joint step sequence time becomes the key factor to improve the cutting efficiency of the whole machine. SUMMARY

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the present application is to provide a partition plate type fiber cord joint device and method which shortens the joint step sequence time and simplifies the equipment structure.

[0005] The partition plate type fiber cord joint device which can solve the above technical problems has the technical scheme that a conveying belt platform is provided for conveying the cut fiber cord pieces forward, and the difference is that:

[0006] 1. The conveying step length of the conveying belt platform is designed to be equal to the length of the fiber cord piece.

[0007] 2. A partition plate mechanism is arranged above the conveying belt platform corresponding to the cutting position of the fiber cord piece, the partition plate mechanism comprises a material blocking partition plate which moves forward and backward under the drive of a servo transmission assembly. When the material blocking partition plate moves backward, it blocks the tail of the spliced fiber cord strip to isolate it from the edge of the fiber cord piece being pulled. After the fiber cord is cut into pieces, the material blocking partition plate moves forward to release the head of the fiber cord piece to make it lap with the tail of the fiber cord strip.

[0008] 3. A pressure joint mechanism is arranged above the conveying belt platform at a position one piece of fiber cord piece away from the front of the partition plate mechanism, the pressure joint mechanism comprises a pressure cylinder assembly I driven pressure joint plate, and the pressure joint plate is pressed to compact the fiber cord piece at the lap joint with the fiber cord strip.

[0009] Further, the said partition mechanism further comprises an anti-uplift partition for preventing the uplift of the tail end of the fiber cord, which is attached to the material blocking partition and moves forward and backward under the drive of the pressure cylinder assembly II.

[0010] The fiber cord joint device with the partition type fiber cord joint device has the following process steps for splicing the fiber cord sheet:

[0011] 1. Before the clamping mechanism pulls the material, the material blocking partition extends backward to the material blocking position and blocks above the tail end of the fiber cord, so as to prevent the sticking phenomenon of the fiber cord with the uncut fiber cord during the clamping and pulling process.

[0012] 2. After the clamping mechanism pulls the material to the set length, the cutting mechanism cuts the fiber cord into sheets, and the sheet body of the fiber cord sheet falls on the conveyor belt platform, and the sheet head of the fiber cord sheet is overlapped on the tail end of the fiber cord.

[0013] 3. The material blocking partition is pulled forward to remove the isolation, and the sheet head of the fiber cord sheet is overlapped on the tail end of the fiber cord.

[0014] 4. The conveyor belt platform steps forward to convey the fiber cord and the fiber cord sheet, and the overlapping part of the fiber cord sheet and the fiber cord is conveyed to the lower part of the pressure joint mechanism.

[0015] 5. The pressure cylinder assembly I drives the pressure plate to press on the overlapping part of the fiber cord sheet and the fiber cord, so as to compact the connection of the fiber cord sheet and the fiber cord.

[0016] The beneficial effects of the present application are:

[0017] 1. The present application synchronously integrates the pressure joint process with the clamping and cutting process, shortens the cutting joint cycle period of the production line, and improves the production efficiency of the whole production line.

[0018] 2. The present application has simple structure and reliable work, simplifies the structure of the original production line, shortens the equipment assembly and debugging period, and facilitates the maintenance of the equipment maintenance personnel.

[0019] 3. The present application can realize the production demand of covering all width specifications of the fiber body.

[0020] 4. The present application uses a single wide conveyor belt combined with a narrow conveyor belt on one side to assist in conveying the cord, which can effectively improve the stability of the equipment and reduce the manufacturing cost of the equipment.

[0021] 5. The present application solves the problem of inconsistent overlapping amount on both sides of the cord joint caused by the inconsistent speed of multiple conveyor belts in the original technology. DETAILED DESCRIPTION

[0032] The partition mechanism 2 includes anti-warping partition 2-3 and material blocking partition 2-1 in upper and lower positions, the material blocking partition 2-1 is higher than the thickness of a piece of fiber cord 9, the anti-warping partition 2-3 is arranged on the material blocking partition 2-1 and the rear lower ends of the two are horizontal, the left and right widths of the material blocking partition 2-1 and the anti-warping partition 2-3 are equal and equal to the sum of the width of the narrow conveyor belt 10 and the width of the conveyor belt platform 1, the front upper ends of the anti-warping partition 2-3 and the material blocking partition 2-1 are respectively installed on the moving frame I and the moving frame II, the moving frame I and the moving frame II are both slidingly installed on the partition frame 2-5, the moving frame I drives the anti-warping partition 2-3 to move forward and backward under the drive of the pressure cylinder assembly II 2-4, the moving frame II drives the material blocking partition 2-1 to move forward and backward under the drive of the servo transmission assembly 2-2 (servo motor + synchronous belt transmission pair), as shown in Figure 4 .

[0033] The pressing mechanism 3 includes pressure cylinder assembly I 3-2 arranged on the moving frame III 3-3 of the pressing frame, the moving frame III 3-3 drives the pressure cylinder assembly I 3-2 to adjust the pressing position forward and backward under the drive of power, the lower end of the pressure cylinder assembly I 3-2 is installed with pressing plate 3-1, the left and right widths of the pressing plate 3-1 are equal to the sum of the width of the narrow conveyor belt 10 and the width of the conveyor belt platform 1, the pressure cylinder assembly I 3-2 drives the pressing plate 3-1 to press down, Figure 1 、 Figure 2 , as shown in Fig. 5 (c). ​

[0034] The splicing of the fiber cord sheet 4 into a strip is carried out by using the partition type fiber cord joint device of the present application, and the joint process steps are as follows:

[0035] 1. Before the clamping mechanism 6 pulls the fiber cord 9, the material blocking partition 2-1 of the partition mechanism 2 is extended backward to the working position to block the tail of the spliced fiber cord strip 5, and the rear part of the conveying belt platform 1 is raised to the horizontal material receiving position, as shown in Fig. 5(a).

[0036] 2. When the clamping mechanism 6 pulls the fiber cord 9, the air blowing mechanism 8 is raised to blow air between the fiber cord 9 and the conveying belt platform 1 to form an air bed, preventing the fiber cord 9 from adhering to the conveying belt platform 1. During the pulling process, the front side material edge of the fiber cord 9 is not connected to the tail of the fiber cord strip 5 due to the isolation of the material blocking partition 2-1, as shown in Fig. 5(a).

[0037] 3. After the clamping mechanism 6 pulls the fiber cord 9 to the set length, the air blowing mechanism 8 stops blowing and is lowered, and the part of the fiber cord 9 pulled into position falls on the conveying belt platform 1, and the front side material edge of the fiber cord 9 falls on the material blocking partition 2-1, as shown in Fig. 5(a).

[0038] 4. After the air blowing mechanism 8 is lowered, the upper cutter of the cutting mechanism 7 moves downward to cut the fiber cord 9 into a sheet, the material blocking partition 2-1 is pulled forward to release the isolation of the fiber cord sheet 4, so that the front side material edge of the fiber cord sheet 4 and the tail of the fiber cord strip 5 are connected end to end, and the vacuum suction function of the conveying belt platform 1 starts to work to suck the fiber cord sheet 4 and the fiber cord strip 5 onto the conveying belt platform 1, as shown in Fig. 5(b).

[0039] 5. The conveying belt platform 1 is lowered to separate the fiber cord sheet 4 from the cutting edge, and after the conveying belt platform 1 is lowered to the set position, the conveying belt platform 1 conveys the fiber cord sheet 4 and the fiber cord strip 5 connected together forward by a length of one fiber cord sheet 4 to position the connection part below the pressing mechanism 3.

[0040] 6. The pressing plate 3-1 of the pressing mechanism 3 is pressed down on the connection part under the drive of the pressure cylinder assembly I 3-2, so as to compact the fiber cord sheet 4 and the fiber cord strip 5, and form a good adhesive force between them to prevent the joint from opening.

[0041] 7. The above process steps 1-6 can be repeated to realize the continuous splicing of the fiber cord sheet 4.

[0042] In the above process steps:

[0043] 1. When the width of the fiber cord 9 changes, the joint pressing position will change accordingly, and the joint pressing mechanism 3 can be adjusted in position according to the measured value of the width measuring system.

[0044] 2、When the end of the fiber cord 5 appears to be warped, the baffle mechanism 2 is switched to the anti-warping mode by manual operation, i.e. the anti-warping baffle 2-3 is operated to work, and the isolation and lapping between the two fiber cord pieces 4 are completed by the backward extension and forward retraction of the anti-warping baffle 2-3. During the retraction of the anti-warping baffle 2-3, the end of the fiber cord 5 is fixed by the material blocking baffle 2-1 to prevent the deformation of the end of the fiber cord 5 from affecting the lapping effect.

[0045] 3、The change of the edge position of the fiber cord 9 is detected by the edge detection sensor 12 (corresponding to the baffle position outside the right side of the conveyor belt platform 1), and the baffle mechanism 2 and the pressing mechanism 3 can be adjusted in position according to the feedback value of the edge detection sensor 12.

[0046] 4、The conveying direction of the conveyor belt platform 1 has a fine adjustment function. During the conveying of the fiber cord 5, when the lapped joint of the fiber cord 5 passes through the edge detection sensor 11 (installed on the moving frame III 3-3), the edge deviation of the cord joint is read, and the left and right swing angles of the rear end of the conveyor belt platform 1 are adjusted according to one or more sets of cord joint edge deviation to eliminate the edge deviation of the cord joint, i.e. the angle between the conveying direction of the conveyor belt platform 1 and the cutting knife is adjusted to realize the edge deviation correction of the lapped joint.

[0047] 5、In the normal working mode, the anti-warping baffle 2-3 is always in the forward retracted state and does not participate in the work, and only the forward and backward movement of the material blocking baffle 2-1 is used to complete the isolation and lapping between the fiber cord pieces 4 and the fiber cord 5.
