Description

Technical Field

[0001] This utility model relates to the field of paper tube polishing technology, and in particular to a polishing device for the end of a wire spindle paper tube. Background Technology

[0002] Spindle tubes are key consumables in chemical fiber production, mainly used for high-speed winding of chemical fiber filaments (such as polyester, nylon, spandex, etc.) to form cylindrical spindles (yarn spindles). As the winding skeleton of the yarn, it maintains the stability of the spindle shape and can withstand high-speed winding of 8000-12000 rpm. At the same time, it also plays a protective role, preventing the chemical fibers from being crushed or deformed during transportation and storage.

[0003] Paper tubes undergo multiple processes during production, including winding, cutting, and polishing. After cutting, protrusions and burrs form at the cut edges of the paper tube ends, affecting surface smoothness and increasing the risk of filament breakage. Existing paper tube polishing equipment is complex, and the equipment requires stopping during material handling, preventing continuous polishing. The purpose of this invention is to propose a new paper tube polishing device to solve these problems, enabling continuous, non-stop processing and improving production efficiency. Utility Model Content

[0004] To address the aforementioned technical deficiencies, this invention provides a grinding device for the ends of a paper tube, which enables rapid grinding of both ends of the paper tube with high efficiency.

[0012] The base is fixedly connected to the mover of the linear motor. An electromagnet is vertically installed at the center of the base. At least three sliding grooves are arranged radially on the base. A slider is installed in the sliding groove. A spring is installed in the sliding groove between the electromagnet and the slider. The two ends of the spring are fixed to the inner end of the sliding groove and the slider, respectively.

[0013] A vertically upward column is provided on the slider. When the electromagnet is energized, the column and the electromagnet attract each other.

[0014] Each column is equipped with a sleeve, which rotates freely with the column to form a rotating pair.

[0015] A linear motor is installed at each end between the sandpaper strips on the two supports, with the corresponding linear motor extending from between the sandpaper strips to the outside.

Attached Figure Description

[0020] Figure 2 for Figure 1 A magnified view of a portion of point A in the middle. Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Example 1:

[0023] like Figure 1 , Figure 2 As shown, this utility model discloses a grinding device for the end of a wire spindle paper tube, comprising:

[0024] A linear motor 1, wherein a plurality of paper tube clamps 3 are provided on the mover 101 of the linear motor 1, and the paper tube clamps 3 are arranged at intervals along the moving direction of the mover 101 of the linear motor 1.

[0025] The paper tube clamp 3 is used to fit the wire spindle paper tube, and the wire spindle paper tube can rotate freely relative to the mover 101 of the linear motor 1;

[0026] Support 2 is provided on both sides of linear motor 1. Two vertical rollers 201 are provided on each side of support 2. Sandpaper strips 202 are fitted on the rollers 201 on the same side of support 2. A power mechanism is provided on each support 2. The power mechanism is connected to one of the rollers 201 through transmission.

[0027] One end of the linear motor 1 is located between the sandpaper strips 202 on the two brackets 2, and the other end extends to the outside of the sandpaper strips 202;

[0028] The middle part of the sandpaper strip 202 is smooth.

[0029] The linear motor 1 is a known existing product, and its specific structure will not be described in detail. The mover 101 of the linear motor 1 can perform linear reciprocating motion. A row of paper tube clamps 3 are arranged on the mover 101 of the linear motor 1 along its direction of motion for clamping paper tubes. Supports 2 are set on both sides of the linear motor 1. Abrasive paper strips 202 are mounted on the supports 2 via rollers 201. A grinding channel is formed between the abrasive paper strips 202 on the two supports 2. The spacing between the abrasive paper strips 202 is the same and matches the diameter of the paper tube to be ground. One end of the linear motor 1 is located inside the grinding channel, and the other end is located outside the grinding channel. In actual use, the mover 101 of the linear motor 1 can be moved to the outside of the grinding channel, so that the paper tubes can be clamped on the paper tube clamps 3. The paper tubes are arranged in a row along the direction of motion of the linear motor 1. When the mover 101 of the linear motor 1 moves the paper tube to the grinding channel, the paper tube contacts the abrasive paper strips 202 and can be ground.

[0030] Since the clamped wire spindle tube and the mover 101 of the linear motor 1 rotate freely, a power mechanism is used to drive the corresponding roller 201 and sandpaper belt 202 to rotate in order for the sandpaper belt 202 to polish the wire spindle tube. In actual operation, the power mechanism can control the sandpaper belts 202 on both sides to run in opposite directions. Due to the opposite movement of the sandpaper belts 202, the wire spindle tube is clamped and rotated. Because the linear motor 1 drives the wire spindle tube in reciprocating motion, relative movement occurs between the wire spindle tube and the sandpaper belt 202, thus achieving polishing of the wire spindle tube by the sandpaper belt 202. Since only the two ends of the tube need to be polished, the middle part of the sandpaper belt 202 is smooth, while the two ends are rough; that is, the rough part of the sandpaper belt 202 corresponds to the two ends of the wire spindle tube, achieving polishing of both ends of the wire spindle tube.

[0031] The linear motor 1 drives the paper tube to reciprocate for grinding at both ends, which greatly improves the processing and grinding efficiency and is simple and convenient to operate.

[0032] The paper tube clamp 3 includes a base 31, an electromagnet 32, a slider 34, a column 36, and a spring 35;

[0033] The base 31 is fixedly connected to the mover 101 of the linear motor 1. An electromagnet 32 ​​is vertically arranged at the center of the base 31. At least three sliding grooves 33 are arranged radially on the base 31. A slider 34 is arranged in the sliding groove 33. A spring 35 is arranged in the sliding groove 33 between the electromagnet 32 ​​and the slider 34. The two ends of the spring 35 are fixed to the inner end of the sliding groove 33 and the slider 34, respectively.

[0034] A vertically upward column 36 is provided on the slider 34. When the electromagnet 32 ​​is energized, the column 36 and the electromagnet 32 ​​attract each other.

[0035] Each column 36 is provided with a sleeve 37, and the sleeve 37 and the column 36 can rotate freely to form a rotating pair.

[0036] The base 31 of the paper tube clamp 3 is fixed to the mover 101 of the linear motor 1. A vertically upward electromagnet 32 ​​is positioned at the center of the base 31. A radially arranged groove 33 is formed on the base 31, and a slider 34 is disposed within each groove 33. In this embodiment, three evenly spaced grooves 33 are used, and a spring 35 is installed within each groove 33. In its natural state, the spring 35 pushes the slider 34 outward. A column 36 is mounted on the slider 34, and a sleeve 37 is fitted onto the column 36. The sleeve 37 and the column 36 are freely rotatable, forming a rotating pair. The column 36 is made of a metal that can be attracted by the electromagnet 32, such as iron. Therefore, in practical use, when assembling the wire spindle paper tube, the electromagnet 32 ​​can be energized to generate magnetism, thereby attracting the column 36. The column 36 then overcomes the elastic force of the spring 35, causing the slider 34 to move closer to the electromagnet 32 ​​within the slide groove 33. This reduces the distance between the three columns 36, allowing the wire spindle paper tube to be directly fitted onto the outside of the three columns 36. Then, when the power to the electromagnet 32 ​​is turned off, the column 36 is pushed outward under the action of the spring 35, generating tension between it and the wire spindle paper tube, clamping the wire spindle paper tube. Since the sleeve 37 on the column 36 is in direct contact with the wire spindle paper tube, the wire spindle paper tube can still rotate freely under the action of the three sleeves 37.

[0037] The control method of this utility model is to achieve automatic control through an external controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0038] A linear motor 1 is installed at each end between the sandpaper strips 202 on the two supports 2, and the corresponding linear motor 1 extends from between the sandpaper strips 202 to the outside.

[0039] Linear motors 1 are installed at both ends of the sandpaper belts 202. When the paper tube on the mover 101 of one linear motor 1 is grinding between the sandpaper belts 202, the paper tube on the mover 101 of the other linear motor 1 moves to the outside of the sandpaper belts 202, allowing for replacement by the operator. Repeating this process enables continuous operation of the equipment, improves the grinding efficiency of the paper tubes, and avoids equipment stoppages during loading and unloading.

[0040] Two slide rails 204 are provided below each bracket 2. The slide rails 204 are perpendicular to the linear motor 1. A sliding seat 203 is slidably mounted on the slide rails 204. The bracket 2 is fixed to the sliding seat 203 below it. A positioning bolt 205 is provided on the sliding seat 203. The positioning bolt 205 is used to limit the position of the sliding seat 203 on the slide rails 204.

[0041] Since the outer diameter of the wire spindle paper tubes varies in actual use, in order to adapt to the grinding of different sizes of wire spindle paper tubes, a bracket 2 is set on the sliding seat 203, and the sliding seat 203 is slidably connected to the slide rail 204. According to actual needs, the position of the sliding seat 203 on the slide rail 204 is adjusted and fixed by the positioning bolt 205 to adjust the distance between the two sandpaper belts 202, thereby adapting to the grinding of wire spindle paper tubes of different diameters.

[0042] A polytetrafluoroethylene (PTFE) layer is sprayed onto the surface of the sleeve 37. The PTFE layer has a low coefficient of friction, which reduces wear on the inside of the paper tube.
