Description

Technical Field

[0001] This utility model relates to the field of plastic adhesive strip production technology, and in particular to a traction cutting mechanism for plastic adhesive strip production. Background Technology

[0002] In the production and processing of plastic strips, the traction cutting mechanism is a key piece of equipment to ensure production continuity and initial molding quality. Its core function is to stably transport the extruded strips to the designated position and cut them precisely according to the preset size, which directly affects the production efficiency and subsequent suitability of the strips. As the industry continues to increase its requirements for the precision and consistency of strip products, the stability and reliability of the traction cutting device are receiving more and more attention.

[0003] Application No. 202421119339.9 discloses a traction cutting device for producing plastic strips. This device achieves stable and continuous feeding of the strips during the conveying process by optimizing the structural design of the traction mechanism, effectively reducing problems such as deformation and surface defects caused by unstable traction, and significantly improving production speed and processing efficiency. However, in practical applications, when the plastic strip is pulled to the cutting part by the traction mechanism, the part of the strip away from the traction end is suspended in the air. The strip is prone to sag under its own weight or lateral displacement under the influence of slight external vibrations, causing the strip conveying path to deviate from the preset trajectory. At the same time, during the cutting operation, the strip is only constrained by unidirectional tension through the traction end. The impact force generated when the cutting blade contacts the strip will cause local shaking at the cutting part. This shaking will directly cause problems such as tilting of the cutting surface and deviation of the strip cutting length, seriously affecting the dimensional accuracy and end face flatness of the strip product, making it difficult to meet the needs of high-precision production scenarios.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, the traction cutting mechanism for producing plastic strips provided by this utility model includes a table 1. A traction clamping assembly 2 is provided on one side of the upper end of the table 1. The traction clamping assembly 2 includes a fixed seat 21 connected to the upper end of the table 1. Two cylinders 22 are symmetrically installed on the outer wall of the fixed seat 21. The free ends of the two cylinders 22 are connected to clamping plates 23. A first moving block 24 is fixedly connected to the lower end of the fixed seat 21. The first moving block 24 is embedded in a moving groove reserved in the table 1. A first electric telescopic rod 25 is installed inside the moving groove. The free end of the first electric telescopic rod 25 is fixedly connected to the first moving block 24. A support base 6 is fixedly connected to the lower end of the table 1.

[0030] Furthermore, a cutting assembly 3 is provided on one side of the traction clamping assembly 2. The cutting assembly 3 includes a base plate 31 connected to the upper end face of the platform 1. A fixing plate 32 is fixedly connected to one side of the upper end face of the base plate 31. Two synchronous wheels 34 are rotatably connected to the fixing plate 32. One end of the upper synchronous wheel 34 is connected to a cutting blade 33. A synchronous belt 35 is sleeved on the outside of the two synchronous wheels 34. The end of the lower synchronous wheel 34 away from the fixing plate 32 is connected to a drive motor 36.

[0031] The cutting assembly 3 also includes a second movable block 37 fixedly connected to the lower end face of the base plate 31. The second movable block 37 is embedded in the movable groove reserved in the table plate 1, and a second electric telescopic rod 38 is connected to one side of the second movable block 37. The second electric telescopic rod 38 is installed in the movable groove.

[0032] As can be seen from the above, during use, firstly, cylinder 22 is activated. The output power of cylinder 22 pushes clamping plate 23 to move towards the rubber strip to be processed until clamping plate 23 is tightly attached to the surface of rubber strip, thus achieving a stable clamping of rubber strip. Then, the first electric telescopic rod 25 is activated. Through the retraction action of the first electric telescopic rod 25, the first moving block 24 connected to it is driven to slide smoothly along a preset trajectory in the moving groove reserved in the table 1, thereby pulling the clamped rubber strip through the production process at a uniform speed, ensuring the consistency of rubber strip delivery. At the same time, drive motor 36 is activated to drive... The output shaft of motor 36 drives the active synchronous pulley 34 to rotate. The active synchronous pulley 34 transmits power to the driven synchronous pulley 34 through the synchronous belt 35, thereby driving the cutting blade 33 to rotate, completing the power preparation before cutting. When the rubber strip is conveyed to the preset cutting position, the second electric telescopic rod 38 is activated. The second electric telescopic rod 38 pushes the second moving block 37 to move in the corresponding moving groove, driving the rotating cutting blade 33 to feed towards the rubber strip, ultimately achieving fast and precise cutting of the rubber strip. Throughout the process, clamping and traction conveying work together to effectively prevent the rubber strip from shaking or deviating during cutting.

[0033] refer to Figure 1 Figure 2 , Figures 5-7 As shown, the cutting assembly 3 has a support structure 4 on the side away from the traction clamping assembly 2, which is used to provide stable support for the suspended part of the rubber strip away from the traction end during the traction process.

[0034] The support structure 4 includes two support side plates 41 symmetrically fixedly connected to the upper end face of the platform 1. Limiting rods 42 are fixedly connected to the side walls of the two support side plates 41. A sleeve block 43 is sleeved on the outside of the limiting rod 42. An L-shaped block 44 is fixedly connected to the outer wall of the sleeve block 43. A support seat 45 is fixedly connected to one end of the L-shaped block 44. A connector 46 is provided on one side of the support seat 45.

[0035] The connector 46 includes a connecting rod 461 fixedly connected to one side of the outer wall of the support base 45. An elastic rod 462 is connected inside the connecting rod 461. A fixed bracket 463 is connected outside the elastic rod 462. The fixed bracket 463 is fixedly connected to the upper end face of the clamping plate 23. A screw rod 464 is threadedly connected to the slot pre-drilled in the fixed bracket 463. An insert 465 is threaded to the outside of the screw rod 464. A groove 466 is opened on the outer wall of the elastic rod 462 to cooperate with the insert 465. One end of the screw rod 464 passes through and extends to the upper end of the fixed bracket 463 and is fixedly connected to an end block 467.

[0036] Through the above technical solution:

[0037] Before clamping the adhesive strip, the operator pulls the free end of the elastic rod 462 and inserts it into the pre-drilled groove in the fixed bracket 463, initially achieving a pre-connection between the support structure 4 and the clamping mechanism. Then, the operator holds and rotates the end block 467, causing the lead screw 464 to rotate synchronously. This causes the insert 465 at the lower end of the lead screw 464 to descend vertically and engage in the corresponding groove 466, completing the secure locking of the support base 45 and the clamping plate 23, ensuring the reliability of their connection. During the process of the cylinder 22 pushing the clamping plate 23 to clamp the adhesive strip... The support base 45 moves synchronously with the clamping plate 23. At this time, the sleeve block 43, which is fixedly connected to the support base 45 via the L-shaped block 44, will slide smoothly along the outside of the limiting rod 42, so that the suspended part of the rubber strip away from the traction end forms effective support. This not only completely counteracts the downward tendency caused by the weight of the rubber strip itself, but also resists the lateral displacement caused by slight external disturbances through the rigid constraint of the limiting rod 42, so that the rubber strip always maintains a straight conveying posture, ensuring the overlap between the conveying path of the rubber strip and the preset trajectory, and significantly reducing the cutting reference deviation caused by the conveying deviation.

[0038] Additionally, refer to Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the auxiliary component 5, which is located on one side of the traction clamping component 2 and is positioned opposite to the cutting component 3, is used to form a multi-dimensional rigid constraint on the cutting part of the adhesive strip.

[0039] The auxiliary component 5 includes a connecting seat 51 fixedly connected to the outside of one of the connecting rods 461. A connecting plate 52 is fixedly connected to the inner side wall of the connecting seat 51. An upper pressure plate 53 and a lower pressure plate 54 are connected sequentially from top to bottom to the side wall of the connecting plate 52 away from the connecting seat 51. An adjusting member 55 is provided at the connection between the upper pressure plate 53 and the lower pressure plate 54 and the connecting plate 52.

[0040] The adjusting component 55 includes a groove 551 formed on the side wall of the connecting plate 52. A threaded rod 553 is rotatably connected inside the groove 551. Two sliders 552 are threadedly connected to the outside of the threaded rod 553. The two sliders 552 are respectively connected to the upper pressure plate 53 and the lower pressure plate 54. A top block 554 is fixedly connected to the upper screw end face of the threaded rod 553. A side block 555 is connected to the lower end face of the top block 554. An insert block 556 is fixedly connected to the side block 555 near the side wall of the connecting plate 52. A slot 557 matching the insert block 556 is formed on the outer wall of the connecting plate 52. An elastic block 558 is connected in a cavity reserved in the inner wall of the top block 554. The elastic block 558 is hinged to the side block 555.

[0041] Through the above technical solution:

[0042] After the clamping plate 23 clamps and fixes the rubber strip, its upper pressure plate 53 and lower pressure plate 54 will cover the upper and lower surfaces of the rubber strip cutting area, forming a rigid constraint on the area near the cutting point. At the moment the cutting blade 33 contacts the rubber strip, this constraint can directly offset the vibration generated by the cutting impact force, preventing the cutting surface from tilting due to local shaking of the rubber strip. Before the constraint is fixed, the operator can pull the side block 555, and use the elastic deformation of the elastic block 558 to drive the insert block 556 out of the slot 557, releasing the lock on the threaded rod 553. Then, the end of the threaded rod 553 is rotated in both directions to drive the threaded rod 553 to rotate. At this time, the slider 55, which is threadedly connected to the threaded rod 553, will... 2 will move smoothly within the pre-reserved groove 551 of the connecting plate 52, thereby driving the upper pressure plate 53 to rise and fall, realizing flexible adjustment of the distance between the upper pressure plate 53 and the lower pressure plate 54 to adapt to plastic strips of different thicknesses; after the distance is adjusted to match the thickness of the strip, the side block 555 is released, the elastic block 558 resets and pushes the insert block 556 to re-insert into the slot 557, completing the locking and fixing of the threaded rod 553. This auxiliary component 5 has the dual benefits of adaptability adjustment and constraint, which not only expands the application range of the device, but also offsets the cutting impact force through multi-dimensional fixing, greatly improving the flatness of the cutting surface, and effectively solving the problems of cutting length error and end face tilt in the prior art.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
