Description

Technical Field

[0001] This utility model relates to the technical field of standardized pallet conveying system conveyor line modules based on standard aluminum profiles, specifically to a conveyor line module with a quick-change friction strip structure. Background Technology

[0002] In the current industry, standardized pallet conveyor systems use friction strips to support the movement of the chain in the conveyor line module. Because the outgoing chain at the top of the conveyor line module carries pallets and goods, the outgoing friction strips in contact with it suffer severe wear. Replacing these friction strips is a significant challenge in conveyor line module maintenance. To ensure stable and fixed installation of the friction strips, the current technical solution involves tightly fitting them into a grooved profile of the conveyor line. Replacing the friction strips requires removing components from both ends of the profile and pulling the friction strip out from one side. This disassembly and replacement process is time-consuming, labor-intensive, and inefficient, resulting in high worker workload. Utility Model Content

[0003] In view of the defects of the existing technology, the purpose of this utility model is to provide a conveyor line module with a quick-change friction strip structure, which realizes the quick replacement of the outgoing friction strip from the top of the line profile through the combination structure of friction strip and fastening strip.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a conveyor line module with a quick-change friction strip structure, including a line profile, the top of the line profile is provided with a going-out cavity for accommodating the going-out chain, and going-out friction strip limiting grooves are symmetrically arranged on both sides of the going-out cavity. Each going-out friction strip limiting groove is equipped with a going-out friction strip and several fasteners, and the several fasteners are spaced apart between the side surface of the going-out friction strip and the side surface of the going-out friction strip limiting groove.

[0005] Furthermore, the fastener includes an integrated extrusion part and a positioning part, which form an L-shaped structure. The extrusion part is assembled between the side surface of the outgoing friction strip and the groove stop of the outgoing friction strip limiting groove, so that the outgoing friction strip and the outgoing friction strip limiting groove are tightly fitted. The positioning part is fastened to the upper surface of the groove stop of the outgoing friction strip limiting groove.

[0006] Furthermore, the surface of the extrusion part that contacts the outgoing friction strip is set as a plane that fits into the outgoing friction strip, and the bottom of the surface of the extrusion part that is away from the outgoing friction strip is set as an inclined surface, so that the bottom of the extrusion part forms a wedge-shaped structure that is wider at the top and narrower at the bottom.

[0007] Furthermore, an opening groove is provided on the wedge-shaped structure at the bottom of the extrusion section, and the opening groove extends through the extrusion section along its length. The opening groove provides space for deformation during the installation and removal of the extrusion section.

[0008] Furthermore, several of the buckle strips are disposed on the side of the outgoing friction strip away from the center of the outgoing cavity, and the outer groove edge of the outgoing friction strip limiting groove forms a first inner buckle convex angle, which cooperates with the wedge structure at the bottom of the extrusion part to restrict the upward displacement of the extrusion part.

[0009] Furthermore, the bottom of the outgoing friction strip limiting groove is configured as a structure where a horizontal plane and an inclined plane connect. The horizontal plane is close to the center of the outgoing cavity, and the inclined plane is far from the center of the outgoing cavity and slopes upward. The bottom of the buckle is in contact with the inclined structure at the bottom of the outgoing friction strip limiting groove, and the bottom of the outgoing friction strip is in contact with the bottom of the outgoing friction strip limiting groove. The outgoing friction strip is restricted from moving outward by the inclined structure at the bottom of the outgoing friction strip limiting groove.

[0010] Furthermore, the opposite side surface of the two outgoing friction strips is the inner surface, and the inner surface of the outgoing friction strip is provided with a positioning groove, which penetrates the outgoing friction strip along its length; a second inner buckling convex angle is formed on the upper part of the inner groove stop edge of the outgoing friction strip limiting groove, and the second inner buckling convex angle is embedded in the positioning groove of the outgoing friction strip.

[0011] Furthermore, the lower surface of the second inner buckle protrusion is an inclined surface, so that the second inner buckle protrusion forms a wedge-shaped protrusion, and the lower surface of the second inner buckle protrusion is parallel to the inclined surface structure of the bottom of the groove of the outgoing friction strip limiting groove.

[0012] Preferably, the lower surface of the second inner protruding corner is inclined at 45°, and the inclined surface structure at the bottom of the groove of the outgoing friction strip limiting groove is inclined at 45°.

[0013] Preferably, after the buckle is disassembled, the assembly space where the buckle is located forms a clearance space for the outgoing friction strip. When the outgoing friction strip moves to the limit position along the inclined surface structure at the bottom of the outgoing friction strip limiting groove, the positioning groove of the outgoing friction strip is completely separated from the second inner buckle protrusion.

[0014] Furthermore, the linear profile has a return cavity below the outgoing cavity for accommodating the return chain. A return friction strip is installed inside the return cavity. The cross-section of the return friction strip is square. Return friction strip stops are provided at both ends of the return friction strip. The return friction strip stops are connected to the end faces of both ends of the linear profile by bolts.

[0015] Furthermore, the outgoing friction strip supports the rollers on both sides of the outgoing chain, the center wheel of the outgoing chain is suspended in the outgoing cavity, and the returning friction strip supports the center wheel of the returning chain.

[0016] Furthermore, the fastener is made of UPE with a molecular weight of 300w or less, and the length of the fastener ranges from 1 to 5m. The fastener can be cut into different lengths.

[0017] Furthermore, connecting grooves are provided on both sides of the linear profile, and the driving and driven components at both ends of the linear profile are fixed to the connecting grooves on both sides of the linear profile by bolts. The connecting grooves facilitate the determination of the assembly height position of the driving and driven components.

[0018] The beneficial effects of this utility model are as follows: This utility model uses several independent fasteners assembled within the limiting groove of the outgoing friction strip, creating a tight fit between the outgoing friction strip and the limiting groove. This prevents the outgoing friction strip from loosening during operation. The fasteners are small in size, facilitating disassembly and assembly. When the outgoing friction strip needs to be replaced, first remove the fasteners. The space where the fasteners are located forms a clearance space for the outgoing friction strip. Move the outgoing friction strip into this clearance space, creating a clearance fit between the outgoing friction strip and the limiting groove. Then, remove the outgoing friction strip from above the profile and reassemble it. This fastener assembly allows for quick friction strip replacement; the operation is simple, convenient, and saves time and effort. Attached Figure Description

[0030] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0031] Example 1

[0032] See appendix Figure 1-9 A conveyor line module with a quick-change friction strip structure includes a line profile 1. The top of the line profile 1 has a forward cavity 2 for accommodating the forward chain. Symmetrically arranged on both sides of the forward cavity 2 are forward friction strip limiting grooves 3. Each forward friction strip limiting groove 3 is fitted with a forward friction strip 4 and several fasteners 5, which are spaced apart between the side surfaces of the forward friction strip 4 and the side surfaces of the forward friction strip limiting groove 3. Below the forward cavity 2, the line profile 1 has a return cavity 6 for accommodating the return chain, and a return friction strip 7 is fitted within the return cavity 6.

[0033] Based on the above technical solution, the lengths of the outgoing friction strip 4 and the returning friction strip 7 are the same as the length of the linear profile 1. The fastener 5, as a pressing and limiting workpiece, is relatively short for easy operation and is spaced out, limiting and fixing the outgoing friction strip 4 at intervals. The two outgoing friction strip limiting grooves 3 are symmetrically arranged along the center of the outgoing cavity, and the two outgoing friction strips 4 are symmetrically arranged along the center of the outgoing cavity. The fastener 5 is located on the side of the outgoing friction strip limiting groove 3 away from the center of the outgoing cavity 2, that is, the two rows of fasteners 5 are located on the outside of the two outgoing friction strip limiting grooves 3, away from the outgoing chain, to avoid contact between the fastener 5 and the outgoing chain, which would affect the stability of the chain drive.

[0034] Furthermore, the fastener 5 includes an integrated extrusion part 5.1 and a positioning part 5.2, which form an L-shaped structure. The extrusion part 5.1 is assembled between the side surface of the outgoing friction strip 4 and the groove stop of the outgoing friction strip limiting groove 3, so that the outgoing friction strip 4 and the outgoing friction strip limiting groove 3 form a tight fit. The positioning part 5.2 is fastened to the upper surface of the groove stop of the outgoing friction strip limiting groove 3.

[0035] Based on the above technical solution, the fastener 5 is made of an elastic material with deformation capability, which can quickly complete the assembly and disassembly process through compression deformation. The lower surface of the positioning part 5.2 has a positioning boss 5.21, which is positioned with the upper surface of the groove stop edge.

[0036] Furthermore, the surface of the extrusion part 5.1 that contacts the outgoing friction strip is set as a plane that fits with the outgoing friction strip, and the bottom of the surface of the extrusion part away from the outgoing friction strip is set as an inclined surface 5.11, so that the bottom of the extrusion part forms a wedge-shaped structure that is wider at the top and narrower at the bottom.

[0037] Furthermore, an opening groove 5.12 is provided on the wedge-shaped structure at the bottom of the extrusion part 5.1, and the opening groove 5.12 extends through the extrusion part 5.1 along its length. The opening groove 5.12 provides space for deformation during the installation and removal of the extrusion part 5.1.

[0038] Furthermore, several of the buckle strips 5 are disposed on the side of the outgoing friction strip 4 away from the center of the outgoing cavity, and the outer groove edge of the outgoing friction strip limiting groove 3 forms a first inner buckle convex angle 3.1. The first inner buckle convex angle 3.1 cooperates with the wedge-shaped structure at the bottom of the extrusion part 5.1 to restrict the upward displacement of the extrusion part 5.1.

[0039] Furthermore, the bottom of the outgoing friction strip limiting groove 3 is configured with a structure in which a horizontal surface 3.3 and an inclined surface 3.4 are connected. The horizontal surface 3.3 is close to the center of the outgoing cavity, and the inclined surface 3.4 is far from the center of the outgoing cavity and slopes upward. The bottom of the buckle 5 is in contact with the inclined surface 3.4 at the bottom of the outgoing friction strip limiting groove, and the bottom of the outgoing friction strip 4 is in contact with the bottom of the outgoing friction strip limiting groove 3. The outgoing friction strip 4 is restricted from moving outward by the inclined surface 3.4 at the bottom of the outgoing friction strip limiting groove.

[0040] Furthermore, the opposing surfaces of the two outgoing friction strips 4 are inner surfaces, and the inner surfaces of the outgoing friction strips are provided with positioning grooves 4.1, which penetrate the outgoing friction strips 4 along their length. A second inward-facing protruding angle 3.2 is formed on the upper part of the inner groove stop of the outgoing friction strip limiting groove 3, and this second inward-facing protruding angle 3.2 is embedded in the positioning groove 4.1 of the outgoing friction strip. The second inward-facing protruding angle 3.2 prevents the outgoing friction strips 4 from moving upward and disengaging from the outgoing friction strip limiting groove 3.

[0041] Furthermore, the lower surface 3.21 of the second inner buckling protrusion 3.2 is an inclined surface, forming a wedge-shaped protrusion. The lower surface 3.21 of the second inner buckling protrusion 3.2 is the contact mating surface with the positioning groove 4.1 of the outgoing friction strip. The lower surface 3.21 of the second inner buckling protrusion 3.2 is parallel to the inclined surface 3.4 structure at the bottom of the groove of the outgoing friction strip limiting groove. This ensures that both sides of the outgoing friction strip can move along the same inclined angle, preventing the outgoing friction strip from getting stuck in a certain position.

[0042] In one embodiment, the lower surface of the second inner protrusion 3.2 is inclined at 45°, and the inclined surface structure 3.4 at the bottom of the groove of the outgoing friction strip limiting groove is inclined at 45°. When the outgoing friction strip moves along the inclined surface, the horizontal displacement is the same as the vertical displacement. This allows for good displacement in both the horizontal and vertical directions within a relatively small movement space.

[0043] Based on the above technical solution, the assembly space of the buckle 5 is both the compression space of the outgoing friction strip 4 and the clearance space of the outgoing friction strip 4. During buckle assembly, the buckle 5 compresses the outgoing friction strip 4, causing the outgoing friction strip 4 to form a tight fit with the outgoing friction strip limiting groove 3. After the buckle 5 is disassembled, the assembly space where the buckle 5 is located forms a clearance space for the outgoing friction strip 4. When the outgoing friction strip 4 moves to its limit position along the inclined structure 3.4 at the bottom of the outgoing friction strip limiting groove 3, the positioning groove 4.1 of the outgoing friction strip completely separates from the second inner buckling convex angle 3.2. Figure 9 As shown. The second inner protrusion 3.2 can no longer restrict the position of the outgoing friction strip 4, and the outgoing friction strip 4 can be removed from above the line profile 1. When replacing the new outgoing friction strip, insert the new outgoing friction strip from the inclined side above the outgoing friction strip limiting groove 3, push the outgoing friction strip down along the inclined structure 3.4 until the second inner protrusion 3.2 is fully embedded in the positioning groove 4.1 of the outgoing friction strip, and then insert the buckle 5 into the driving gap between the outgoing friction strip 4 and the outgoing friction strip limiting groove 3.

[0044] Furthermore, the cross-section of the return friction strip 7 is square, and return friction strip stops 8 are provided at both ends of the return friction strip 7. The return friction strip stops 8 are connected to the end faces of both ends of the linear profile 1 by bolts.

[0045] Based on the above technical solution, the outgoing friction strip 4 needs to connect with the friction strips on the top of the active and driven components. Therefore, the outgoing friction strip 4 does not need to be equipped with a stop edge. Under normal conditions, the return friction strip achieves its limiting function through the housings of the active and driven components connected at both ends of the line profile. However, the outgoing and return friction strip structures of this application can be applied to conveyor line modules with different speed chains, such as... Figure 1-2 As shown, this is a line profile adapted for 2.5x speed chains, and can be fitted with BS25-C212A speed chains; as... Figure 3-4 As shown, this is a linear profile adapted to a single-speed chain, which can be fitted with a 12BS chain. Different chain center pulleys have different diameters, resulting in different return cavity heights for different linear profiles. Therefore, different profiles require matching active and driven component housings with appropriate slotted positions to ensure that the slotted positions of the housings expose the return cavity and block the return friction strip, thus achieving the housing's limiting function for the return friction strip. In this embodiment, the return friction strip stop 8 is directly set on the linear profile 1, avoiding the requirement for high precision in the slotting of the active and driven component housings.

[0046] Furthermore, the chain is formed by connecting several snap ring chain links in sequence. Each chain link includes a central wheel for load and rollers on both sides of the central wheel. Two outgoing friction strips support the rollers on both sides of the outgoing chain. The central wheel of the outgoing chain is suspended in the outgoing cavity. The returning friction strip supports the central wheel of the returning chain.

[0047] Based on the above technical solution, the outgoing chain needs to support the pallet above the conveyor line. Therefore, the rollers on both sides of the central wheel are supported by the outgoing friction strip. The bottom of the groove in the outgoing cavity is lower than the bottom of the limiting groove of the outgoing friction strip, so that the central wheel is suspended in the air to support the pallet and items. Since the return chain is unloaded, the central wheel of the return chain can directly contact and support the return friction strip. Only one return friction strip is needed, making it easy to replace. The return friction strip has a square cross-section for easy disassembly and installation.

[0048] Furthermore, the outgoing friction strip is made of steel, the conveyor line is tens of meters long, and the pallets being conveyed are heavy-duty pallets. The fastening strips are made of UPE with a molecular weight of 300w or less, and each fastening strip is 3m long. They can be cut to different lengths as needed, and the spacing between adjacent fastening strips can be adjusted according to different working conditions.

[0049] Furthermore, connecting grooves are provided on both sides of the linear profile, and the driving and driven components at both ends of the linear profile are fixed to the connecting grooves on both sides of the linear profile by bolts. The connecting grooves facilitate the determination of the assembly height position of the driving and driven components.

[0050] Example 2

[0051] See appendix Figure 10 The technical solution of Embodiment 2 is basically the same as that of Embodiment 1, except that the opening groove 5.12 on the wedge-shaped structure of the buckle extrusion part is omitted. The extrusion part 5.1 of the buckle 5 is fully assembled between the side surface of the outgoing friction strip 4 and the groove stop of the outgoing friction strip limiting groove 3, so that the outgoing friction strip 4 and the outgoing friction strip limiting groove 3 form a tight fit. The upper thickness of the extrusion part is 1±0.1mm, and the thickness of the wedge-shaped structure of the extrusion part is 1.18mm. The extrusion part 5.1 is directly assembled by the elastic extrusion of the material itself. This buckle structure is easier to process.
