Description

Technical Field

[0001] The invention relates to the technical field of rope threading machines, and in particular to a feeding mechanism of a rope threading machine. Background Art

[0002] The paper bag feeding mechanism of the rope threading machine can automatically deliver the bag body to the next station. Publication No. (CN202021315150.9) discloses a feeding mechanism of the rope threading machine that realizes the automation of bag body transportation; the feeding mechanism includes a material table, a conveyor belt is arranged on the material table to drive the bag body to move forward, and a push plate is also arranged above the material table. The push plate is slidably arranged on the guide rod, and the guide rod is transversely arranged on the frame. The push plate is connected to a counterweight block that drives it to move to the left. The counterweight block allows the push plate to push the bag body to move under the action of gravity, and finally realizes the smooth feeding of the mechanism;

[0003] However, the push plate of the above mechanism is not precisely synchronized with the drive of the feed belt. During the feeding process, since the upper end of the paper bag is thin and the lower end is thick, the upper end of the paper bag will tilt toward the push plate, causing the adsorption mechanism to be unable to stably adsorb on the surface of the bag. At the same time, the push plate will squeeze the bag under the action of the counterweight block, but due to the gap between the bags, the upper end of the bag will be squeezed forward, causing the bag to tilt forward, which will eventually lead to unstable bag feeding and paper jams. Therefore, manual sorting is required, which increases the workload of the staff. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a feeding mechanism of a rope threading machine, which realizes the synchronous advancement of the push plate and the conveyor belt through a synchronous belt, so that the movement of the bag body is smoother and the tilting of the bag body caused by the asynchronous upper and lower ends of the bag body during the conveying process is avoided.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a feeding mechanism of a rope threading machine, including a material table, the material table is provided with a conveyor belt assembly and a push plate assembly; the conveyor belt assembly includes a conveyor belt for driving paper bags forward, and the material table is provided with a driving wheel and a driven wheel for driving the conveyor belt to move, and is characterized in that the push plate assembly includes a synchronous wheel and a secondary wheel, a synchronous belt is arranged between the synchronous wheel and the secondary wheel, a strip-shaped through groove arranged along the moving direction of the synchronous belt is arranged on the material table, and a fixed seat is also connected to the synchronous belt, and a push plate passing through the strip-shaped through groove is detachably connected to the fixed seat; and it also includes a driving device for synchronously driving the synchronous belt and the conveyor belt to advance synchronously.

[0006] The present invention is further configured such that the driving device includes a connecting shaft connected to a servo motor, the driving wheel is connected to the connecting shaft via a one-way bearing, and the synchronous wheel is fixedly connected to the connecting shaft.

[0007] The present invention is further configured such that a clamping claw mechanism for clamping the push plate is disposed on the fixed seat, and a control device for controlling the opening and closing of the clamping claw mechanism is also disposed on the fixed seat.

[0008] The present invention is further configured such that the control device is a telescopic cylinder.

[0009] The present invention is further configured such that the clamping mechanism includes a clamping cover hinged to the side of the fixed seat facing the push plate, a mounting groove matched with the push plate is provided between the clamping cover and the fixed seat, and the clamping cover is also hinged to the output end of the telescopic cylinder.

[0010] The present invention is further configured such that a guide rail is provided at the bottom of the material table along the moving direction of the paper bag, and the fixing seat is slidably connected to the material table via the guide rail.

[0011] The present invention is further configured such that the conveyor belt assembly is provided with two groups, which are symmetrically arranged on both sides of the push plate assembly.

[0012] The present invention is further configured such that a material blocking bracket is provided above the material table.

[0013] The present invention is further configured such that a tensioning wheel matching the conveyor belt is provided on the material table.

[0014] In summary, the beneficial effects of the present invention are:

[0015] Compared with the prior art, the structural design of the invention realizes the synchronous advancement of the push plate and the conveyor belt, thereby accurately and synchronously driving the paper bag to move forward, reducing the tilting caused by the asynchronous movement of the upper and lower ends of the bag body during the movement of the paper bag, so that the adsorption mechanism can better adsorb the paper bag, making the bag feeding process more stable, avoiding paper jams caused by unstable adsorption during the material absorption process, thereby reducing the need for manual sorting of paper bags;

[0016] The movement of the push plate can be controlled by the clamping cover and the fixed seat. When the connecting shaft rotates forward, it can drive the synchronous wheel and the driving wheel to rotate forward, so that the conveyor belt and the push plate can move forward synchronously. When the clamping cover on the fixed seat is opened, the servo motor controls the connecting shaft to reverse. At this time, the driving wheel will not rotate under the action of the one-way bearing, and the synchronous belt will move in the opposite direction, so that the fixed seat moves away from the paper bag, so that the fixed seat is separated from the push plate, and then the push plate is inserted into the fixed seat, which reduces the labor of the staff when adding materials, and at the same time realizes that the normal transportation of the paper bags is not affected while adding materials.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-4 As shown, this embodiment discloses a feeding mechanism of a rope threading machine, including a material platform 1, wherein the material platform 1 is provided with a conveyor belt assembly 2 and a push plate assembly 3; the conveyor belt assembly 2 includes a conveyor belt 203, and the material platform 1 is provided with a driving wheel 201 and a driven wheel 202 for driving the conveyor belt 203 to rotate, and the push plate assembly 3 includes a synchronous wheel 301 and a secondary wheel 302 corresponding to the synchronous wheel 301, and a synchronous belt 303 is arranged between the synchronous wheel 301 and the secondary wheel 302, and the material platform 1 is provided with a strip-shaped through groove 305 arranged along the moving direction of the synchronous belt 303. The synchronous belt 303 is also connected to a fixed seat 6, and a push plate 304 passing through a strip-shaped through slot 305 is detachably connected to the fixed seat 6; it also includes a driving device 5 for synchronously driving the synchronous belt 303 and the conveyor belt 203 to advance synchronously, and the driving device 5 includes a connecting shaft 501 connected to a servo motor 503, and a one-way bearing 502 is provided on the connecting shaft 501. The driving wheel 201 is connected to the connecting shaft 501 through the one-way bearing 502, and the synchronous wheel 301 is fixedly connected to the connecting shaft 501; the connecting shaft 501 is also connected to a servo motor 503;

[0025] By setting the connecting shaft 501, the push plate 304 and the conveyor belt 203 can move forward accurately and synchronously. When the servo motor 503 drives the connecting shaft 501 to rotate forward, the synchronous wheel 301 on the connecting shaft 501 rotates synchronously with the driving wheel 201, driving the conveyor belt 203 and the synchronous belt 303 to move forward, so that the upper and lower ends of the paper bag can move forward synchronously, preventing the paper bag from tilting due to inconsistent thickness at the upper and lower ends during the feeding process, thereby making the paper bag more stably adsorbed, avoiding the need for manual sorting of paper bags due to paper jams, and reducing the labor of staff.

[0026] By setting the servo motor 503, the process of conveying a paper bag is as follows: the servo motor 503 drives the push plate 304 to move forward a distance of N units, then retreat less than N units, and then move forward a distance of N units; thereby, the paper bags have a sorting process. When conveying the paper bags, the servo motor 503 drives the conveyor belt 203 and the synchronous belt 303 forward, so that the upper and lower ends of the paper bags move synchronously, avoiding the tilting of the paper bags, and then the synchronous belt 303 retreats, so that the push plate 304 is away from the paper bags. In this way, when the push plate 304 pushes the paper bags forward, it will have a forward force on the paper bags, so that the front end of the paper bags can be in a vertical state, which is convenient for the stable adsorption of the air nozzle; avoiding the gap between the paper bags causing them to tilt and making the adsorption unstable; at this time, due to the action of the one-way bearing 502, the conveyor belts 203 on both sides of the material table 1 will not move, avoiding driving the lower end of the paper bags to retreat, making the conveying of the paper bags more stable.

[0027] like Figure 5 As shown, the fixed seat 6 is provided with a clamping mechanism 9 for controlling the movement of the push plate 304, and the fixed seat 6 is also provided with a control device 603 for controlling the opening and closing of the clamping mechanism 9; the control device 603 is a telescopic cylinder; the clamping mechanism 9 includes a mounting groove 601 arranged at one end of the fixed seat 6 facing the push plate 304 and a clamping cover 602 matching the mounting groove 601, one end of the clamping cover 602 is hinged to the fixed seat 6 and is also hinged to the output end of the telescopic cylinder.

[0028] The same side end where the clamping cover 602 is hinged to the fixed seat 6 is hinged with the output end of the telescopic cylinder. The telescopic cylinder and the clamping cover 602 are set at an inclined angle. The opening and closing of the clamping cover 602 is controlled by controlling the extension and retraction of the cylinder output end. When the output end of the telescopic cylinder is extended, the clamping cover 602 fits against the side of the mounting groove 601, thereby preventing the push plate 304 from being separated from the mounting groove 601, so that the push plate 304 can be driven by the fixed seat 6; when the output end of the cylinder retracts, it will drive the clamping cover 602 to open, and then when the servo motor 503 reverses and drives the synchronous belt 303 to reverse, the fixed seat 6 will move in the direction away from the paper bag, thereby disengaging from the push plate 304 and completing the disassembly of the push plate 304.

[0029] When adding material is needed, first place the paper bag on the material table 1, and let the paper bag fit with the push plate 304, so that the push plate 304 is clamped between the paper bags, and then the cylinder output end contracts, so that the clamping claw mechanism 9 releases the clamping of the push plate 304, and then the servo motor 503 reverses to drive the fixed seat 6 to move along the guide rail 7 away from the paper bag to the rear of the last paper bag, and then another push plate 304 is installed in the installation groove 601, and the cylinder output end is extended, so that the clamping cover 602 is closed, so that the fixed seat 6 can drive the push plate 304, and then the push plate 304 located between the paper bags is taken out, and the fixed seat 6 drives the push plate 304 to fit with the paper bags. Compared with the prior art, during the feeding process, the staff does not need to move the push plate 304, which reduces the labor of the staff and improves efficiency.

[0030] like Figure 2 As shown, in this embodiment, a guide rail 7 is provided at the bottom of the material table 1 along the movement direction of the synchronous belt 303, and a slide groove 8 matching the guide rail 7 is provided on the fixed seat 6. Through the cooperation of the guide rail 7 and the slide groove 8, the fixed seat 6 can be supported to prevent the gravity of the fixed seat 6 from deforming the synchronous belt 303, and at the same time ensure that the fixed seat 6 will not shake during the movement, making its movement more stable.

[0031] A material blocking bracket 10 is arranged above the material platform 1 .

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the design concept of the present invention should be included in the protection scope of the present invention.
