Description

Technical fields:

[0001] This utility model belongs to the technical field of plastic straw processing equipment, and specifically refers to an auxiliary support assembly for conveying plastic straws. Background technology:

[0002] Currently, the processing of disposable plastic straws mainly involves extruding a long strip of plastic tube using an extruder, and then cutting the long strip of plastic tube into segments using a cutting device. To effectively transport the long strip of plastic tube to the cutting device, a conveying device that clamps and transports it forward is used. For example, a cutting device for plastic straws disclosed in a Chinese utility model patent (authorization announcement number CN220807737U) has an upper conveyor belt assembly and a lower conveyor belt assembly spaced vertically on a frame located in front of the conveying channel. The conveyor belts of the upper and lower conveyor belt assemblies rotate in opposite directions, and a conveying gap is formed between the upper and lower conveyor belt assemblies to clamp and transport the plastic straw forward.

[0003] However, in actual production and processing, it was found that the long plastic tubes were prone to deviation or even detachment between the upper and lower conveyor belt assemblies. Therefore, operators needed to frequently stop the machine to adjust and straighten the position of the long plastic tubes, which was time-consuming and seriously affected the processing efficiency of plastic straws. Summary of the Invention:

[0004] The purpose of this invention is to provide an auxiliary support assembly for conveying plastic straws, which can effectively limit the conveying position of the plastic straws, thereby effectively solving the problem of plastic straws deviating from their designated position in the straw conveying device.

[0005] This utility model is implemented as follows:

[0006] An auxiliary support assembly for conveying plastic straws includes an auxiliary frame located outside the input or output end of a straw conveying device. The auxiliary frame has two limiting posts spaced apart along a direction perpendicular to the straw conveying direction, forming a limiting space between the two limiting posts for conveying the plastic straws.

[0007] In the above-mentioned auxiliary support assembly for conveying plastic straws, the auxiliary frame has a movable groove along the direction perpendicular to the straw conveying direction, and the bottom of the limiting post is slidably engaged in the movable groove by a slider.

[0008] In the aforementioned auxiliary support assembly for conveying plastic straws, the movable slide is a dovetail groove structure, and the slider corresponds to the movable slide structure.

[0009] In the above-mentioned auxiliary support assembly for conveying plastic straws, the slider has a mating through hole, the bottom end of the limiting post is threaded to the mating through hole, and the bottom surface of the limiting post can extend out of the mating through hole and abut against the bottom surface of the movable slide groove.

[0010] In the above-mentioned auxiliary support assembly for conveying plastic straws, the auxiliary frame includes a fixed support and a support seat that is slidably connected to the fixed support in a vertical direction, and the limiting post is disposed on the support seat.

[0011] In the aforementioned auxiliary support assembly for conveying plastic straws, the fixed support has two or more vertical strip-shaped through holes along the vertical direction, and a fastening bolt passes through the support base and the vertical strip-shaped through holes and is screwed with a fastening nut.

[0012] In the above-mentioned auxiliary support assembly for conveying plastic straws, the fixed support has two or more horizontal strip-shaped through holes, and two fastening bolts pass through the horizontal strip-shaped through holes and are screwed to the external plane.

[0013] The outstanding advantages of this utility model compared to the prior art are:

[0014] This utility model has a simple structure, reasonable design and low cost. By designing a limiting space on the outside of the input or output end of the straw conveying device, the conveying position of the plastic straw can be effectively restricted, thereby effectively solving the problem of plastic straws running off-center in the straw conveying device.

[0017] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 :

[0018] An auxiliary support assembly for conveying plastic straws includes an auxiliary frame 2 located outside the input or output end of a straw conveying device 1. The auxiliary frame 2 is provided with two limiting posts 3 spaced apart along a direction perpendicular to the straw conveying direction, and a limiting space is formed between the two limiting posts 3 for conveying plastic straws.

[0019] This utility model has a simple structure, reasonable design and low cost. By designing a limiting space on the outside of the input or output end of the straw conveying device 1, the conveying position of the plastic straw can be effectively restricted, thereby effectively solving the problem of the plastic straw running off course in the straw conveying device 1.

[0020] Furthermore, in order to adjust the conveying position of the plastic straw and to accommodate the processing and conveying of plastic straws with different outer diameters, the auxiliary frame 2 is provided with a movable groove 4 perpendicular to the straw conveying direction. The bottom of the limiting post 3 is slidably engaged within the movable groove 4 via a slider. That is, by adjusting the position of the two limiting posts 3 within the movable groove 4, the position of the limiting space and the width for the plastic straw to pass through can be adjusted.

[0021] Furthermore, in this embodiment, the movable slide 4 is a dovetail groove structure, and the slider corresponds to the movable slide 4 structure.

[0022] In order to lock the slider in the position of the movable slide groove 4, the slider is provided with a mating through hole, the bottom end of the limiting post 3 is threaded to the mating through hole, and the bottom surface of the limiting post 3 can extend out of the mating through hole and abut against the bottom surface of the movable slide groove 4.
