Description

Technical Field

[0001] This utility model relates to the field of rubber band stretching technology, specifically a convenient rubber band stretching device. Background Technology

[0002] Currently, elasticity in various elastic fabrics is achieved through composite elastic bands (spandex filaments). However, the initial preparation of composite elastic bands (spandex filaments) requires stretching the elastic bands onto multiple elastic band guide rollers according to a fixed arrangement spacing and sequence. This process requires stretching each elastic band individually and repeatedly stretching it onto multiple sets of elastic band guide rollers. This process is time-consuming and labor-intensive, greatly affecting production efficiency. Furthermore, multiple elastic bands are prone to breakage during operation. Because the spacing between the elastic bands is generally close, it is very easy to cause chain accidents, and in most cases, the elastic bands need to be stretched again.

[0003] In view of this, further optimizations will be made to address the aforementioned issues. Utility Model Content

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.

[0015] Please see Figures 1 to 6 This utility model provides a convenient elastic band stretching device; it includes a support base, and a guide unit and a stretching unit disposed on the support base; The guide unit includes a rotatable rotating member 1, and the outer peripheral surface of the rotating member 1 is provided with a guide structure extending along its axial direction for traction and guidance of the elastic band. The stretching unit includes multiple lateral traction components 2 for stretching the elastic band, and the multiple lateral traction components 2 are arranged in parallel. The guiding unit works in conjunction with the stretching unit to achieve the stretching process of the elastic band.

[0016] The rotating component 1 includes a detachable support rod 101 located on the support base. The outer wall of the support rod 101 is threadedly connected to a sleeve 102 that can be adjusted left and right. The outer wall of the sleeve 102 is provided with several rubber guide wheels 103 at equal intervals, and different colors can be marked on its surface for easy inspection later. The inner wall of the support base is provided with threaded columns 3 on opposite sides. The support rod 101 includes internally threaded cylinders 104 fitted on both ends. The internally threaded cylinders 104 are detachably connected to the surface of the threaded columns 3.

[0017] By rotating the internal threaded cylinder 104, the rotating component 1 can be disassembled from the threaded column 3, which facilitates later maintenance; Rotating the sleeve 102 allows it to move axially along the support rod 101 (which has threads on its outer wall), facilitating adjustment according to usage requirements.

[0018] The transverse traction component 2 includes an upper extension plate 201. A spring 202 is fixedly connected to the bottom edge of the upper extension plate 201. The bottom end of the spring 202 is fixedly connected to the upper surface of the lower extension plate 203. Limiting plates 204 are provided on both sides of the upper extension plate 201 and the lower extension plate 203. The two sides of the limiting plates 204 are fixedly connected to the opposite sides of the inner wall of the support base through support plates. The surfaces of the upper extension plate 201 and the lower extension plate 203 are provided with protruding guide blocks 205. The right end of the guide block 205 is provided with a positioning groove 206.

When the cleaning plate 6 moves upward, it can be retracted inside the N-shaped frame 4. The N-shaped frame 4 has a groove inside, which makes it easy to retract inside when not in use. When the brush bristles 7 move downward and abut against the elastic guide wheel 103, rotating the sleeve at this time can easily clean the dirt on its surface, reducing the need for subsequent cleaning steps.

[0022] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that provides control.

If the lateral position of the rubber band guide wheel 103 needs to be adjusted, the sleeve 102 can be rotated to move it left and right along the threaded outer wall of the support rod 101 until it is positioned as required. Multiple rubber bands are then embedded into the grooves of each guide block 205 of the rubber band stretching auxiliary equipment. The tail of each rubber band is then inserted into the positioning groove 206 on the right end of the corresponding guide block 205 to achieve the initial fixation of the rubber band. Move the rubber band stretching auxiliary device (lateral traction component 2) loaded with rubber bands to the front of the rubber band transmission roller (rotating component 1). By observing the regular color markings on the surface of the rubber band guide wheel 103, align the fixing block on the auxiliary device (achieved by the limit plate 204 and spring 202 assembly) with the corresponding color groove of the target rubber band guide wheel 103. Press down on the upper extension plate 201 with a little force to compress the spring 202, so that the guide block 205 can be smoothly engaged in the groove of the corresponding rubber band guide wheel 103; after confirming that the auxiliary equipment is stably engaged, move the entire device smoothly along the predetermined stretching direction of the rubber band. Under the guidance of the guide block 205, the rubber band is accurately wound onto the corresponding rubber band guide wheel 103 according to the preset trajectory.
