Technical Field

[0001] The utility model relates to the technical field of clamping mechanisms, in particular to a clamping mechanism for the stuffing end of a pillow. Background Art

[0002] A pillow is a commonly used bedding in daily sleep, mainly composed of a pillow core and a pillowcase. Its main function is to support the head and make the neck get comfortable support. It is one of the indispensable bedding in people's daily life;

[0003] Currently, in the process of manufacturing pillows, it is usually necessary for workers to manually put the opening of the pillow core sleeve on the stuffing end of the stuffing device and then stuff it. Since the worker needs to hold the pillow core sleeve all the time during the stuffing process to ensure the stable connection between the opening of the pillow core sleeve and the stuffing end, the workload of the worker is increased. Therefore, to solve this problem, designing a clamping mechanism for the stuffing end of a pillow is what we need to consider. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a clamping mechanism for the stuffing end of a pillow. In view of the clamping problem, a clamping and limiting mechanism is set up. By driving two arc-shaped clamping plates and two L-shaped support plates to move towards each other by a motor, the pillow core sleeve can be stably clamped and stuffed. There is no need for workers to hold the pillow core sleeve all the time, reducing the workload. At the same time, after stuffing is completed, automatic unloading can be carried out, improving the stuffing efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A clamping mechanism for the stuffing end of a pillow, including a workbench, the upper end of the workbench is fixedly connected with a U-shaped support frame, and a stuffing pipe is arranged at the upper end of the U-shaped support frame; a clamping and limiting mechanism, the clamping and limiting mechanism includes a motor installed on the right side of the U-shaped support frame, a bidirectional threaded rod is rotatably connected between the left and right inner walls of the U-shaped support frame, the right end of the bidirectional threaded rod penetrates through the right inner wall of the U-shaped support frame and is fixedly connected with the output shaft of the motor, and two first connection bars are threadedly connected to the two threaded ends of the bidirectional threaded rod, and arc-shaped clamping plates are fixedly connected to the opposite sides of the two first connection bars.

Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Referring to Figures 1-3 , a clamping mechanism at the down filling end of a pillow includes a workbench 1. A U-shaped support frame 2 is fixedly connected to the upper end of the workbench 1. A down filling tube 3 is provided at the upper end of the U-shaped support frame 2. The rear port of the down filling tube 3 is communicated with a down filling device, so that the pillow core is discharged from the lower port of the down filling tube 3;

[0020] Among them, it further includes a clamping and limiting mechanism. The clamping and limiting mechanism includes a motor 4 installed on the right side of the U-shaped support frame 2. The motor 4 is a servo motor that can change the rotation direction. A bidirectional threaded rod 5 is rotatably connected between the left and right inner walls of the U-shaped support frame 2. The thread directions of the two threaded ends of the bidirectional threaded rod 5 are opposite. The right end of the bidirectional threaded rod 5 penetrates through the right inner wall of the U-shaped support frame 2 and is fixedly connected to the output shaft of the motor 4. First connection bars 6 are threadedly connected to both threaded ends of the bidirectional threaded rod 5. Arc-shaped clamping plates 7 are fixedly connected to the opposite sides of the two first connection bars 6. Both arc-shaped clamping plates 7 cooperate with the down-proof tube 3. The opening of the pillowcase can be clamped at the lower end position of the down-proof tube 3 through the two arc-shaped clamping plates 7, so as to facilitate down filling. Arc-shaped rubber pads 8 are arranged on the inner sides of the two arc-shaped clamping plates 7, which can improve the stability of clamping the pillowcase. L-shaped support plates 9 are fixedly connected to the lower ends of the two first connection bars 6. The two L-shaped support plates 9 can improve the stability of the pillowcase to a certain extent during the down filling process;

[0021] Among them, a guide rod 10 is fixedly connected between the left and right inner walls of the U-shaped support frame 2. The guide rod 10 is slidably connected to the two first connection bars 6. A discharge through groove 11 is arranged on the workbench 1. An inclined surface is arranged in the discharge through groove 11, which can automatically discharge the filled pillowcase to the rear of the workbench 1. A controller 12 is arranged on the front side of the workbench 1. The controller 12 is used to control the operation of the motor 4. Accommodating boxes 13 are fixedly connected to both the left and right sides of the workbench 1. Pillowcases to be filled with down can be placed in the two accommodating boxes 13.

[0022] In the present utility model, before use, the rear end port of the down-proof tube 3 needs to be communicated with the down filling device, and then the opening of the pillowcase to be filled with down is sleeved at the lower end position of the down-proof tube 3. The motor 4 is started to drive the bidirectional threaded rod 5 to rotate, driving the two first connection bars 6, the two arc-shaped clamping plates 7, and the two L-shaped support plates 9 to move towards each other synchronously. The two arc-shaped clamping plates 7 can stably clamp the opening of the pillowcase at the lower end of the down-proof tube 3. At this time, down filling can be started;

[0023] After the down filling is completed, the motor 4 is controlled to drive the two arc-shaped clamping plates 7 to move away from each other, so as to release the clamping and limiting of the pillowcase. The filled pillowcase will automatically fall into the discharge through groove 11 under the influence of gravity and finally move to the rear of the workbench 1. At this time, the staff can limit and fill the next pillowcase. The whole down filling process is convenient and fast, without the need for the staff to always hold the pillowcase for down filling, reducing the workload of the staff, and the subsequent discharge can also be automatic, improving the overall down filling efficiency;

[0024] It is worth mentioning that during the filling of down, the lower ends of the two L-shaped support plates 9 can respectively contact the two side parts at the lower end of the pillow core sleeve and provide a certain degree of support to the contact points, thereby further improving the stability of the pillow core sleeve during the down filling process. And when the two arc-shaped clamping plates 7 release the limit on the pillow core sleeve, the two L-shaped support plates 9 will not affect the natural fall of the pillow core sleeve.

[0025] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent replacements or changes, should be covered within the protection scope of the present invention.
