A cotton feeding device for a cotton filling machine

Abstract

This utility model discloses a cotton outlet device for a cotton filling machine, aiming to solve the technical problem of hand fatigue caused by workers holding dolls for extended periods during existing cotton filling operations. It achieves quick assembly and disassembly through a locking mechanism: a snap-fit ​​half-ring at the end of the connecting pipe engages with a slot at the end of the outlet pipe; a sliding ring drives an insert rod, which, under the action of a tension spring, inserts into the fixed half-ring's insertion hole to complete the locking. The fixing mechanism adopts a rotating ring drive structure: the rotating ring is sleeved on the outer wall of the sliding ring, and its circumferentially opened oblique hole forms a guiding engagement with the vertical hole of the fixed ring. A clamping rod passes through the oblique hole and extends to the side of the connecting pipe. When the rotating ring is rotated, the oblique hole drives the clamping rod to move axially along the vertical hole, causing the end clamping block to clamp or release the fabric product sleeved on the outer wall of the connecting pipe. This device replaces manual holding, significantly reducing labor intensity, and allows for the replacement of different specifications of connecting pipes to accommodate dolls of various sizes, improving production efficiency and operational safety.

Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and in particular to a cotton outlet device for a cotton filling machine. Background Technology

[0002] In textile toy manufacturing, the core production process is to accurately fill cotton wool into the interior of fabric products such as dolls. The filling process involves directly conveying the cotton wool through the discharge pipe of the filling machine into the opening of the doll for filling.

[0003] In actual use, it was found that workers usually need to grip the doll tightly with both hands to fix it on the discharge pipe, which significantly increases the fatigue of the workers' hands. This not only reduces efficiency during long working hours, but also causes certain damage to the workers' health. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that lead to a significant increase in worker hand fatigue, and to propose a cotton outlet device for a cotton filling machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cotton filling machine discharge device includes a cotton filling machine body and a discharge pipe fixedly connected to the cotton filling machine body, and further includes:

[0007] A connecting pipe, wherein the connecting pipe is detachably connected to the discharge pipe;

[0008] The locking mechanism includes a snap-fit ​​half-ring fixed to one end of the connecting pipe and a slot opened at the end of the discharge pipe. The snap-fit ​​half-ring is inserted into the slot to connect the connecting pipe and the discharge pipe.

[0009] The fixing mechanism includes a fixing ring fixedly sleeved on the outer wall of the discharge pipe, a sliding ring slidably sleeved on the outer wall of the discharge pipe, and a rotating ring rotatably sleeved on the outer wall of the sliding ring. The fixing ring has multiple vertical holes circumferentially, and a clamping rod is slidably arranged in each vertical hole. The rotating ring has multiple oblique holes circumferentially, and one end of the clamping rod passes through the oblique hole and extends to the side of the connecting pipe.

[0010] When the rotating ring is rotated, the inclined hole drives the clamping rod to move axially along the vertical hole to clamp or release the fabric product sleeved on the outer wall of the connecting tube.

[0011] In one possible design, a limiting shaft is fixedly installed inside the vertical hole, the clamping rod is slidably sleeved on the outer wall of the limiting shaft, and a compression spring is sleeved on the outer wall of the limiting shaft. The two ends of the compression spring are respectively fixedly connected to the clamping rod and the inner wall of the vertical hole.

[0012] In one possible design, a clamping block is fixedly provided at one end of the clamping rod extending to the side of the connecting pipe, and the clamping surface of the clamping block is parallel to the outer wall of the connecting pipe.

[0013] In one possible design, the vertical holes and the oblique holes are arranged at equal intervals along the circumference of the fixed ring and the rotating ring.

[0014] In one possible design, the locking mechanism further includes a plurality of insert rods fixed to the slip ring and a fixed half-ring disposed at the top of the connecting tube, the fixed half-ring having an insertion hole that mates with the insert rods; the slip ring is driven by a tension spring to insert the insert rods into the insertion hole to lock the connecting tube.

[0015] In one possible design, a tension spring is fitted on the outer wall of the insertion rod, and the two ends of the tension spring are respectively fixedly connected to a slip ring and the outer wall of the discharge pipe.

[0016] In one possible design, the fixed ring is fixedly provided with a limiting rod, and the rotating ring is provided with a limiting hole that cooperates with the limiting rod.

[0017] In this application, during actual use, the rotating ring is first moved backward, which will drive the insert rod to move backward through the slip ring. Then, the connecting tube is moved from top to bottom, so that the bottom locking half ring is inserted into the inside of the slot, connecting the discharge tube and the connecting tube. After that, the slip ring is reset by the tension spring, so that one end of the insert rod is inserted into the inside of the insertion hole, thereby fixing the connecting tube and realizing the installation. When the doll is put on the outer wall of the connecting tube, the rotating ring is rotated. At this time, the connection point between the inclined hole and the vertical hole will change, thereby causing the clamping rod to move. The clamping rod will drive the clamping block to move, fixing the doll in place on the outer wall of the connecting tube, so that the operator does not need to hold the doll tightly with both hands to fill it with cotton.

[0018] In this utility model, the cotton outlet device of the cotton filling machine can be fixed to the connecting pipe and the outlet pipe through a locking mechanism, so that it can be easily disassembled and installed, thereby facilitating the replacement of connecting pipes of different sizes to fit dolls of different sizes.

[0019] In this utility model, the cotton outlet device of the cotton filling machine can directly fix the doll to be filled to the outer wall of the connecting pipe through the fixing mechanism, thereby performing the cotton filling operation and reducing the burden on the hands of the workers.

[0020] In this invention, when in use, dolls and other fabric items can be directly fixed to the surface during filling, thereby reducing the burden on the workers' hands and eliminating the need for them to hold the connecting tube tightly for extended periods. At the same time, the connecting tube can be fixed in place, allowing for direct replacement of connecting tubes of different sizes as needed, thus adapting to dolls and other fabric items of different sizes.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Reference Figure 1 A cotton discharge device includes a cotton filling machine body 1 and a discharge pipe 2, wherein the discharge pipe 2 is fixedly connected to the cotton filling machine body 1, and further includes:

[0028] A locking mechanism for connecting the discharge pipe 2 and the connecting pipe 14, thereby enabling the installation of the connecting pipe 14, and a locking mechanism for fixing the fabric to the outer wall of the connecting pipe 14, thereby reducing the burden on the workers' hands.

[0029] Reference Figure 2 The specific structure of the locking mechanism is as follows:

[0030] A snap-fit ​​half-ring 15 is fixedly installed on the bottom surface of the end of the connecting pipe 14 near the discharge pipe 2, and a slot 18 that mates with the snap-fit ​​half-ring 15 is opened at the corresponding end of the discharge pipe 2. During installation, the snap-fit ​​half-ring 15 is inserted into the slot 18 from above, so that it connects the connecting pipe 14 and the discharge pipe 2, allowing the cotton inside the equipment to be filled into the inside of the doll or other fabric items through the connecting pipe 14.

[0031] Reference Figure 2-3 The specific structure of the fixing mechanism is as follows:

[0032] The fixing mechanism includes a fixed ring 3, a rotating ring 7, and a sliding ring 5. The fixed ring 3 is fixedly sleeved on the outer wall of the discharge pipe 2, the sliding ring 5 is slidably sleeved on the outer wall of the discharge pipe 2, and the rotating ring 7 is rotatably sleeved on the outer wall of the sliding ring 5.

[0033] The surface of the fixing ring 3 is provided with multiple vertical holes 16 at equal intervals. A clamping rod 10 is slidably disposed in the vertical holes 16, and a limiting shaft 17 is fixedly disposed in the vertical holes 16. The clamping rod 10 is slidably sleeved on the outer wall of the limiting shaft 17. At the same time, a compression spring is sleeved on the outer wall of the limiting shaft 17. The two ends of the compression spring are fixedly connected to the outer wall of the clamping rod 10 and the inner wall of the vertical hole 16, respectively, so as to realize the reset of the clamping rod 10 after clamping and moving. The cross section of the clamping rod 10 can be designed as a circle, rectangle, triangle or D-shape to match different strength requirements.

[0034] The surface of the rotating ring 7 has multiple oblique holes 8 at equal intervals. One end of the clamping rod 10 near the rotating ring 7 extends through the oblique holes 8 to the side of the connecting pipe 14, and a clamping block 11 is fixedly installed at this end. When the rotating ring 7 is rotated, the oblique holes 8 drive the clamping rod 10 to move axially along the vertical hole 16, causing the clamping block 11 to press or release the outer wall of the connecting pipe 14. In use, after the doll is placed on the outer wall of the connecting tube 14, the rotating ring 7 is rotated. At this time, the connection point between the oblique hole 8 and the vertical hole 16 will change, thereby causing the clamping rod 10 to move. The clamping rod 10 will then move the clamping block 11 to fix the doll on the outer wall of the connecting tube 14, so that the staff does not need to hold the doll tightly with both hands to fill it with cotton, reducing the burden on the staff's hands. The cross-sectional shape of the connecting tube 14 can be circular, elliptical, polygonal, or irregular (such as petal-shaped) to adapt to the contour requirements of the opening of different fabric products. The clamping surface of the clamping block 11 can be designed as a flat surface, arc surface, serrated or V-shaped groove to improve the gripping force on the edge of the fabric product.

[0035] Reference Figure 2 The auxiliary fixing structure of the locking mechanism is as follows: multiple insertion rods 9 are fixedly installed on the surface of the slip ring 5, and a fixing half-ring 13 is fixedly installed on the top of the end of the connecting pipe 14 near the discharge pipe 2. The surface of the fixing half-ring 13 has multiple insertion holes 12. A tension spring is sleeved on the outer wall of the insertion rod 9, and the two ends of the tension spring are fixedly connected to the outer wall of the slip ring 5 and the discharge pipe 2, respectively. In use, the rotating ring 7 is first moved backward, and the rotating ring 7 will drive the insertion rod 9 to move backward through the slip ring 5. Then, the connecting pipe 14 is clamped to one end of the discharge pipe 2, so that the discharge pipe 2 and the connecting pipe 14 are connected. Then, the slip ring 5 is reset by the tension spring, so that one end of the insertion rod 9 is inserted into the interior of the insertion hole 12, thereby fixing the connecting pipe 14 and realizing the installation.

[0036] When it is necessary to fill dolls of different sizes with cotton, simply replace the connecting tube 4 with one of different diameters at the end to make it compatible.

[0037] In actual use, the positions of the clamping rod 10 and the connecting tube 14 are staggered or the size and position of the two are adjusted so that the connecting tube 14 can be smoothly inserted into one end of the discharge tube 2.

[0038] This application can be used in the field of textile machinery, or in other fields applicable to this application.

[0039] Example 2

[0040] refer to Figure 2 An improvement based on Embodiment 1: A cotton filling machine cotton outlet device, applied in the textile machinery field, wherein a limiting rod 4 is fixedly installed on the surface of the fixed ring 3, and a limiting hole 6 is opened on the surface of the rotating ring 7. When the rotating ring 7 is moved to install the connecting pipe 14, the limiting rod 4 will be inserted into the limiting hole 6, thereby ensuring that the rotating ring 7 can move smoothly. When the rotating ring 7 is rotated to clamp the doll on the outer wall of the connecting pipe 14, the limiting rod 4 and the limiting hole 6 will be misaligned, so that the rotating ring 7 cannot move laterally, thereby ensuring the stability of the installation of the connecting pipe 14.

[0041] However, as is well known to those skilled in the art, the working principle and wiring method of the main body 1 of the cotton filling machine are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
