Description

Technical Field

[0001] This invention belongs to the field of epoxy rebar production, and in particular relates to an epoxy rebar production conveyor frame. Background Technology

[0002] During construction, steel bars are often embedded or precast into walls and beams to improve the building's bending and torsional strength. When a building is located in a coastal area or may be exposed to seawater, epoxy particles are sprayed onto the steel bars to delay corrosion and extend the building's lifespan. This prevents moisture from easily contacting the steel bars, thus preventing corrosion and maintaining the building's strength.

[0003] In current epoxy rebar production, the rebar undergoes cleaning, shot blasting, spraying, and cooling processes sequentially on the production line. However, during this process, the top and bottom sides of the rebar are opposite to the shot blasting nozzles, while the left and right sides are not. Therefore, the efficiency of contact between the left and right sides of the rebar and the shot blasting nozzles, as well as the thickness of the epoxy coating, are limited. If the epoxy particles adhering to the sides of the rebar are to reach the preset standard, the rebar needs to be kept at the epoxy coating station for a longer time. This not only affects processing efficiency, but also results in the epoxy thickness on the top and bottom sides of the rebar exceeding the preset standard by a significant amount when the epoxy thickness on the left and right sides reaches the preset standard, leading to material waste. Utility Model Content

[0004] In view of this, the present invention aims to provide an epoxy rebar production conveyor frame so as to make the epoxy particles on the rebar sprayed more evenly and reduce material waste.

[0005] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0006] An epoxy rebar production conveyor frame includes multiple sets of support wheels arranged along the rebar conveying direction, and each set of support wheels includes two parallel support wheels that rotate synchronously around their own axes; the axial direction of the support wheels is at an angle to the rebar conveying direction, such that the projections of the two support wheels in each set in the rebar conveying direction form a V shape, and when the rebar is placed on the two support wheels of the same set, one side of the rebar is subjected to an upward frictional force, and the other side is subjected to a downward frictional force.

[0007] Furthermore, each support wheel has a chamfered edge.

[0008] Furthermore, the two support wheels in the same group are coaxially connected to the shafts of the transmission wheels, and the transmission wheels on the support wheels in the same group are connected by a transmission mechanism.

[0009] Furthermore, the drive wheel is a sprocket, and the transmission mechanism is a chain.

[0010] Furthermore, it also includes a fixing frame, with each support wheel connected to a fixing frame. Each fixing frame includes a wheel mounting part and a connecting part. The wheel mounting part includes two opposing support side plates. The support wheel is placed between the two support side plates. The rotation shaft of the support wheel is rotatably connected to the two support side plates. The connecting part is placed on the outside of one of the support side plates.

[0011] Furthermore, the connecting part includes a receiving space for accommodating the transmission mechanism, and the receiving space is provided with a plurality of connecting ears on the side away from the mounting part; through holes are respectively opened on the two supporting side plates, and the connecting ear of one of the two adjacent fixing frames corresponds to the through hole of the other fixing frame, and bolts can pass through the connecting ears and through holes to connect the two adjacent fixing frames.

[0012] Furthermore, a cover is provided on the upper part of the accommodating space, and the cover is positioned above the transmission mechanism.

[0013] Furthermore, the connecting lug is placed inside the receiving space, and the bolt includes a threaded section and a support section. When the bolt passes through the connecting lug, the support section can extend into the receiving space; the two ends of the cover plate overlap the support section.

[0014] Furthermore, one side of each end of the cover plate has a clearance groove; the nut that is screwed to the bolt can be placed in the clearance groove.

[0015] Compared with existing technologies, the epoxy rebar production conveyor frame described in this invention has the following advantages:

[0016] This invention employs a method of placing reinforcing bars on multiple sets of parallel support wheels, so that both sides of the reinforcing bars contact the support wheels respectively, forming a deflection force, which allows the reinforcing bars to rotate around their own axis. At the same time, because the support wheels are tilted and the reinforcing bars are placed in the same semicircle on the same side of the support wheels, the reinforcing bars are subjected to a component force along the direction of movement, causing the reinforcing bars to rotate while moving forward, so that shot peening and coating can be distributed more evenly on the surface of the reinforcing bars.

[0017] The contact area between the reinforcing bar and the support wheel is increased by chamfering the two sides of the support wheel.

[0018] A fixed frame is used to provide support for the support wheel. At the same time, bolts that can extend into the receiving space are used so that the cover plate can rest on the bolts. This prevents the epoxy particles that float on the surface of the steel bars after being sprayed with epoxy particles from falling off and affecting the transmission structure, thus reducing transmission efficiency.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] The epoxy rebar 3 production conveyor frame of this utility model includes multiple sets of support wheels 1 arranged along the conveying direction of the rebar 3. Each set of support wheels 1 includes two parallel support wheels 1, and the two support wheels 1 rotate synchronously around their own axes. The axial direction of the support wheels 1 is at an angle to the conveying direction of the rebar 3, so that the projection of the two support wheels 1 in each set in the conveying direction of the rebar 3 is V-shaped. Through the cooperation of multiple sets of support wheels 1, the rebar 3 can be placed within the V-shaped space of each set of support wheels 1, and at this time, the rebar 3 is in contact with the upper part of the support wheel 1. When the two support wheels 1 of each set of support wheels 1 rotate, the two sides of the reinforcing bar 3 are subjected to a forward-tilting frictional force. Through the cooperation of multiple sets of support wheels 1, the forward-moving frictional force propels the reinforcing bar 3 to the forward work position. At the same time, one side of the reinforcing bar 3 is subjected to an upward component force, and the other side is subjected to a downward component force. As a result, the reinforcing bar 3 is subjected to a torsional force around its own axis while moving forward, which causes the reinforcing bar 3 to rotate while moving forward. This allows the reinforcing bar 3 to have more uniform contact with the processed material when it passes through the shot peening and epoxy spraying work positions.

[0032] Specifically, each support wheel 1 has a chamfer 11 on its edge. During operation, the reinforcing bar 3 contacts the chamfer 11 of the support wheel 1, thereby increasing the contact area between the reinforcing bar 3 and the support wheel 1. This makes it easier for the reinforcing bar 3 to rotate while moving forward under friction. To control the rotation of the support wheel 1, transmission wheels 12 are coaxially connected to the shafts of two support wheels 1 in the same group. The transmission wheels 12 on the support wheels 1 in the same group are connected by a transmission mechanism. In this embodiment, the transmission mechanism is a chain, and the transmission wheel 12 is a sprocket. In other embodiments, those skilled in the art can also set gears, connecting rods, etc., as a transmission structure 13 as needed, so that two adjacent support wheels 1 rotate at the same speed, thereby balancing the external forces on both sides of the reinforcing bar 3. This facilitates the uniform forward movement and rotation of the reinforcing bar 3. In production, multiple support wheels 1 can be connected in series through the transmission structure 13 as needed. The outermost support wheel 1 is driven to rotate by a reduction motor, so that the series-connected support wheels 1 rotate through the transmission structure 13, thereby causing multiple reinforcing bars 3 to move forward synchronously for processing.

[0033] The epoxy rebar 3 production conveyor frame of this utility model further includes a fixed frame 2. Each support wheel 1 is connected to a fixed frame 2. Each fixed frame 2 includes a wheel mounting part 21 and a connecting part 22. The wheel mounting part 21 includes two opposing support side plates 211. The support wheel 1 is placed between the two support side plates 211. The rotating shaft of the support wheel 1 is rotatably connected to the two support side plates 211. Those skilled in the art can, as needed, install bearings on the support side plates 211 so that the rotating shaft is connected to the support side plates 211 through the bearings. The connecting part 22 is placed outside one of the support side plates 211. The connecting part 22 includes a receiving space 221 for accommodating the transmission mechanism. The rotating shaft of the support wheel 1 can pass through the support side plate 211 and enter the receiving space 221. The transmission wheel 12 on its rotating shaft is placed in the receiving space 221. More specifically, the ends of the rotating shafts of two adjacent support wheels 1, the transmission wheel 12, and the transmission structure 13 connecting the two transmission wheels 12 are all placed in the receiving space 221. A cover plate 223 is provided on the upper part of the accommodating space 221, and the cover plate 223 is positioned directly above the transmission structure 13. During operation, the cover plate 223 prevents surface epoxy resin particles that may fall from the rotating shaft, as well as dust and water stains that fall after the cleaning process, from falling directly onto the transmission structure 13, thus affecting the transmission efficiency of the transmission structure 13.

[0034] The accommodating space 221 has multiple connecting ears 222 on the side away from the mounting part, and two supporting side plates 211 each have through holes 212. In two adjacent fixing frames 2, the connecting ear 222 of one fixing frame 2 corresponds to the through hole 212 of the other fixing frame 2. Bolts 224 can pass through the connecting ear 222 and the through hole 212 to connect the two adjacent fixing frames 2. Specifically, the bolts 224 pass through the connecting ear 222 and the through hole 212 on the supporting side plate 211, and the supporting side plate 211 and the connecting ear 222 are clamped by nuts 225, so that the two adjacent fixing frames 2 are connected. Furthermore, the connecting lug 222 is positioned inside the receiving space 221, allowing the bolt 224 to enter the receiving space 221 after passing through the connecting lug 222. Specifically, the bolt 224 includes a threaded section and a support section 2241. The nut 225 is threaded to the threaded section, and the support section 2241 extends into the receiving space 221. The height of the bolt 224, positioned above, is higher than the height of the transmission structure 13, allowing both ends of the cover plate 223 to rest on the bolt 224. The cover plate 223 has clearance slots 2231 at both ends, allowing the nut 225, which is threaded to the bolt 224, to be placed within the clearance slots 2231.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
