Description

Technical Field

[0001] This invention relates to the technical field of polyethylene wear-resistant strip processing equipment, and in particular to a fixing device for processing arc-shaped polyethylene wear-resistant strips and its usage method. Background Technology

[0002] Polyethylene wear-resistant strips are extruded from ultra-high molecular weight plastic materials and feature scratch resistance, aging resistance, high and low temperature resistance, and abrasion resistance. They are mainly used in conveyor belts, automated equipment, and conveyor guardrails, such as: large C-shaped guardrails, parallel rail pads, round cap guardrails, flat top guardrails, small C-shaped guardrails, flat pads, K-type lining strips, and Z-type lining strips.

[0003] As a wear-resistant strip on the outer surface of a cylinder, the arc-shaped polyethylene wear-resistant strip is much easier to install than the cylindrical wear-resistant strip because it is open on one side, which is beneficial for installation and replacement in actual use.

[0004] During the production of curved polyethylene wear-resistant strips, anti-slip patterns need to be pressed onto their surface before they can be used. However, while the opening on one side of the curved polyethylene wear-resistant strip facilitates its installation, it also brings the defect that the strip itself is prone to curling. When anti-slip patterns are pressed onto its surface, the curled surface will cause the pressed pattern to be incomplete, resulting in the curved polyethylene wear-resistant strip being substandard. Summary of the Invention

[0005] The purpose of this invention is to provide a fixing device for processing arc-shaped polyethylene wear-resistant strips, so as to solve the problem that when pressing surface patterns on existing arc-shaped polyethylene wear-resistant strips, the curled surface causes incomplete pressing patterns, resulting in unqualified arc-shaped polyethylene wear-resistant strips.

[0006] To solve the above-mentioned technical problems, the present invention provides a fixing device for processing arc-shaped polyethylene wear-resistant strips, including an arc-shaped base for laying arc-shaped polyethylene wear-resistant strips;

[0007] An end clamping structure is provided at both ends of the base, which can clamp and fix the arc-shaped polyethylene wear-resistant strip placed on the base from both ends;

[0008] The end clamping structure includes an outer ring, multiple inner support plates, and a support frame. The support frame is formed from the inside of the outer ring. The inner support plates are slidably connected to the support frame, and the movement of the inner support plates is to move closer to or further away from the outer ring, thereby cooperating with the outer ring to clamp and fix the end of the arc-shaped polyethylene wear-resistant strip.

[0009] The end clamping structure can also rotate around the central axis of the base, and the relative rotation of the two sets of end clamping structures can straighten the curled arc-shaped polyethylene wear-resistant strip.

[0010] Preferably, the support frame is a cross shape that extends outward from the center of the outer ring, and the end of the support frame is fixedly connected to the inner wall of the outer ring.

[0011] Preferably, a rotating sleeve is provided at the center of the support frame, and the rotating sleeve is fitted and can rotate around the central axis.

[0012] Preferably, the support frame is a threaded rod, the inner support plate is sleeved on the threaded rod, and an adjusting nut is also provided on the threaded rod. By turning the adjusting nut, the inner support plate can be pushed toward the outer ring, thereby clamping and fixing the arc-shaped polyethylene wear-resistant strip between the outer ring and the inner support plate.

[0013] Preferably, both sets of end clamping structures are provided with a ratchet mechanism, which limits the rotation angle of the end clamping structure.

[0014] Preferably, the ratchet mechanism includes a ratchet and a pawl. The ratchet is fixedly connected to the central shaft, and one end of the pawl is rotatably connected to the support frame, while the other end contacts the spikes on the outer circumference of the ratchet.

[0015] Preferably, the thorns on the ratchet wheels in the two sets of ratchet mechanisms rotate in opposite directions.

[0016] Preferably, the base includes a plurality of base blocks arranged sequentially along the same axis, wherein the outer surface of the base block is arc-shaped and contacts the inner surface of the arc-shaped polyethylene wear-resistant strip.

[0017] The present invention also provides a method for using a fixing device for processing arc-shaped polyethylene wear-resistant strips, comprising the following steps:

[0018] Step (A): First, measure the length of the arc-shaped polyethylene wear-resistant strip, and then fit the corresponding number of base blocks along a straight line onto the central axis to form a base;

[0019] Step (B): Next, install the end clamping structure and ratchet mechanism at both ends of the base respectively;

[0020] Step (C): Then place the arc-shaped polyethylene wear-resistant strip on the base and insert both ends into the end clamping structure;

[0021] Step (D): Tighten the adjusting nuts in sequence to push the corresponding inner support plate closer to the outer ring until the arc-shaped polyethylene wear-resistant strip between the outer ring and the inner support plate is clamped and fixed.

[0022] Step (E): Then observe the curling angle of the arc-shaped polyethylene wear-resistant strip and rotate the end clamping structure accordingly. At this time, the end clamping structure drives one end of the arc-shaped polyethylene wear-resistant strip to rotate around the central axis until the surface of the arc-shaped polyethylene wear-resistant strip is flat. At this time, the pawl is engaged with the thorn of the corresponding ratchet, thereby locking the rotation angle of the end clamping structure.

[0023] Step (F): After waiting for a period of time, the arc-shaped polyethylene wear-resistant strip is shaped and anti-slip patterns can be pressed onto its flat arc surface.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The fixing device for processing arc-shaped polyethylene wear-resistant strips uses end clamping structures to clamp and fix the arc-shaped polyethylene wear-resistant strips on the base. At the same time, the end clamping structures can also drive the wear-resistant strips to rotate around the central axis, thereby shaping the curled wear-resistant strips into a flat shape.

[0026] 2. A ratchet mechanism is also provided in the end clamping structure. The ratchet mechanism is characterized by its ability to ensure unidirectional rotation of the end clamping structure, thereby limiting the rotation angle of the end clamping structure to meet the requirements of wear-resistant strips with different degrees of curling.

[0027] 3. The base of the fixing device consists of multiple base blocks arranged sequentially along the same axis, so that the base can adjust its length according to the arc-shaped polyethylene wear-resistant strip, thereby adapting to arc-shaped polyethylene wear-resistant strips of different lengths.

[0038] Example 1

[0039] This invention provides a fixing device for processing arc-shaped polyethylene wear-resistant strips. Please refer to [link / reference]. Figure 1 and Figure 2The system includes an arc-shaped base 1 for laying arc-shaped polyethylene wear-resistant strips; end clamping structures 2 are respectively provided at both ends of the base 1, which can clamp and fix the arc-shaped polyethylene wear-resistant strips placed on the base 1 from both ends; the end clamping structure 2 includes an outer ring 201, multiple inner support plates 202 and a support frame 203, the support frame 203 is formed from the outside of the outer ring 201, the inner support plates 202 are slidably connected to the support frame 203, and the movement of the inner support plates 202 is to move closer to or away from the outer ring 201, thereby cooperating with the outer ring 201 to clamp and fix the ends of the arc-shaped polyethylene wear-resistant strips; the end clamping structure 2 can also rotate around the central axis of the base 1, and the relative rotation of the two sets of end clamping structures 2 can shape the curled arc-shaped polyethylene wear-resistant strips into a flat shape.

[0040] Specifically, the support frame 203 is a cross shape that extends outward from the center of the outer ring 201, and the end of the support frame 203 is fixedly connected to the inner wall of the outer ring 201.

[0041] Specifically, a rotating sleeve 204 is provided at the center of the support frame 203. The rotating sleeve 204 is fitted and can rotate around the central axis 3, thereby driving the entire end clamping structure 2 to rotate.

[0042] Specifically, the support frame 203 is a threaded rod, the inner support plate 202 is sleeved on the threaded rod, and an adjusting nut is also provided on the threaded rod. By turning the adjusting nut, the inner support plate 202 can be pushed toward the outer ring 201, thereby clamping and fixing the arc-shaped polyethylene wear-resistant strip between the outer ring 201 and the inner support plate 202, so that the end clamping structure 2 can clamp arc-shaped polyethylene wear-resistant strips of different thicknesses.

[0043] Specifically, the base 1 includes multiple base blocks arranged sequentially along the same axis. The outer surface of the base block is arc-shaped and contacts the inner surface of the arc-shaped polyethylene wear-resistant strip, thereby adapting to arc-shaped polyethylene wear-resistant strips of different lengths.

[0044] For details, please refer to Figure 3 and Figure 4 Both sets of end clamping structures 2 are provided with ratchet mechanisms 4, which limit the rotation angle of the end clamping structures 2.

[0045] Furthermore, the ratchet mechanism 4 includes a ratchet 401 and a pawl 402. The ratchet 401 is fixedly connected to the central shaft 3. One end of the pawl 402 is rotatably connected to the support frame 203, and the other end contacts the spikes on the outer circumference of the ratchet 401. The spikes on the ratchet 401 in the two sets of ratchet mechanisms 4 rotate in opposite directions. That is, the spikes on one set of ratchet 401 rotate clockwise, and the spikes on the other set of ratchet 401 rotate counterclockwise. This allows the two sets of ratchet mechanisms 4 to limit the rotation angle of the corresponding end clamping structure 2 in different directions, thereby adjusting the curling of the wear-resistant strip at different angles.

[0046] Example 2

[0047] This invention also provides a method for using a fixing device for processing arc-shaped polyethylene wear-resistant strips; please refer to [link to relevant documentation]. Figure 5 and Figure 6 It includes the following steps:

[0048] Step (A): First, measure the length of the arc-shaped polyethylene wear-resistant strip 100, and then place the corresponding number of base blocks along a straight line on the central axis 3 to form a base 1. At this time, the base 1 is adapted to the length of the arc-shaped polyethylene wear-resistant strip.

[0049] Step (B): Next, install the end clamping structure 2 and the ratchet mechanism 4 at both ends of the base 1 respectively;

[0050] Step (C): Then place the arc-shaped polyethylene wear-resistant strip 100 on the base 1 and insert both ends into the end clamping structure 2;

[0051] Step (D): Tighten the adjusting nuts in sequence to push the corresponding inner support plate 202 closer to the outer ring 201 until the arc-shaped polyethylene wear-resistant strip 100 between the outer ring 201 and the inner support plate 202 is clamped and fixed.

[0052] Step (E): Then observe the curling angle of the arc-shaped polyethylene wear-resistant strip 100 and rotate the end clamping structure 2 accordingly. At this time, the end clamping structure 2 drives one end of the arc-shaped polyethylene wear-resistant strip 100 to rotate around the central axis until the surface of the arc-shaped polyethylene wear-resistant strip 100 is flat. At this time, the pawl 402 is engaged with the thorn of the corresponding ratchet 401, thereby locking the rotation angle of the end clamping structure 2.

[0053] Step (F): After waiting for a period of time, the arc-shaped polyethylene wear-resistant strip 100 is shaped and anti-slip patterns can be pressed onto its flat arc surface.

[0054] This fixing device for processing arc-shaped polyethylene wear-resistant strips uses end clamping structures to clamp and fix the arc-shaped polyethylene wear-resistant strips to the base. At the same time, the end clamping structures can also drive the wear-resistant strips to rotate around the central axis, thereby shaping and flattening the curled wear-resistant strips. Furthermore, a ratchet mechanism is provided in the end clamping structure. The ratchet mechanism is characterized by ensuring unidirectional rotation of the end clamping structure, thereby limiting the rotation angle of the end clamping structure to meet the needs of wear-resistant strips with different degrees of curling.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
