Description

Technical Field

[0001] This utility model relates to the field of edge banding machines for sheet metal, and specifically to a chain block support structure for an edge banding machine. Background Technology

[0002] Currently, edge banding machines are used for side edge banding, trimming, and polishing of sheet materials. During this process, the sheet materials are conveyed by a conveyor chain assembly, which includes a chain and chain blocks. The chain blocks are installed on the chain links. Specifically, the chain blocks support the bottom surface of the sheet material and are pressed onto the sheet material by pressure rollers to prevent relative movement between the sheet material and the chain blocks. The edge banding machine has a chain block support beam, on which the chain blocks slide, allowing the sheet material to be conveyed in a straight line. The existing chain block support beam is made of aluminum profile and has support feet between the aluminum profile and the machine bed, so that the sheet material can be positioned at a suitable processing height. A semi-circular groove is formed on one side of the top of the aluminum profile, and a straight... The linear optical axis has an arc-shaped groove at the bottom of the chain block. This arc-shaped groove is adapted to slide and connect with the linear optical axis, meaning that the linear optical axis guides the chain block to move linearly. However, since the angle dimensions of the support feet are difficult to keep consistent, and the height dimensions of the aluminum profile will also have errors, as well as the presence of small debris between the linear optical axis and the arc-shaped groove, all of these factors will affect the actual straightness of the linear optical axis. Therefore, the cumulative error will cause the actual movement of the chain block, including up-and-down movement and skewed movement, to lead to problems such as uneven edge sealing and a significant reduction in the processing accuracy of the sheet material. In order to further improve the quality of sheet material products, it is necessary to improve the existing chain block support structure. Summary of the Invention

DETAILED DESCRIPTION

[0019] The utility model will be further described below in combination with the drawings.

[0020] The chain block support structure of the edge banding machine of the utility model, as shown in Figure 1 , comprises a bed body 1 and a chain block support beam 2, the chain block support beam 2 is arranged on the upper side of the bed body 1, and the lower end of the chain block support beam 2 is welded to the bed body 1, as shown in Figures 2 to 4 , the chain block support beam 2 comprises a left side plate 21 and a right side plate 22, the upper end of the left side plate 21 is provided with a cylindrical rail 211 for adapting to the arc-shaped recess 991 of the chain block 99, the lower part of the cylindrical rail 211 is integrally arranged with the left side plate 21, in other words, the lower part of the cylindrical rail 211 is sunken into the left side plate 21 and the lower part of the cylindrical rail 211 is integrally arranged with the left side plate 21, so that actually only the upper part of the cylindrical rail 211 is exposed on the upper end of the left side plate 21, more specifically, as shown in Figure 4 , only the upper half of the cylindrical rail 211 protruding from the upper end of the left side plate 21 is divided by a horizontal diameter, the upper end of the right side plate 22 is formed with a support plane 221 for abutting against the flat bottom surface 992 of the connected chain block 99, the groove cavity 20 for avoiding the chain 98 is formed between the left side plate 21 and the right side plate 22, the oil outlet hole 2111 is formed in the upper part of the left side plate 21, the upper end of the oil outlet hole 2111 penetrates the upper part of the cylindrical rail 211, the oil injection nozzle 3 is arranged on the outer side of the left side plate 21 (here, the "outer side" is relative to the groove cavity 20), the oil injection nozzle 3 is connected to the lower end of the oil outlet hole 2111, specifically, a horizontal blind hole is drilled on the outer side of the left side plate 21, the inner end of the above-mentioned blind hole is communicated with the lower end of the oil outlet hole 2111, the inner thread is processed on the outer end of the above-mentioned blind hole, and the oil injection nozzle 3 is screwed and installed on the above-mentioned inner thread, the oil injection nozzle 3 belongs to the prior art, for example, the "oil injection nozzle structure" with the Chinese utility model patent publication number CN221171754U can be referred to. The combined structure of the oil injection nozzle 3 and the oil outlet hole 2111 can be arranged at intervals of about one meter along the extension direction of the cylindrical rail 211.

[0021] As shown in Figures 5 to 7As shown, the chain 98 is located in the groove cavity 20, and the chain block 99 is laid on the chain block support beam 2. Specifically, the circular arc groove 991 (upper half of the inner cylindrical surface) of the chain block 99 covers the upper part of the cylindrical rail 211, and the flat bottom surface 992 of the chain block 99 is attached to the support flat surface 221. The pressing wheel 5 is arranged to be liftable, and the plate is attached to the chain block 99. The pressing wheel 5 is pressed on the upper side of the plate. The driving sprocket 4 drives the chain 98 to operate, and the chain block 99 can drive the plate to move linearly.

[0022] Since the lower end of the chain block support beam 2 is welded to the upper part of the bed body 1, in other words, the support leg structure is eliminated, or it can be understood that the existing steel support leg and aluminum profile beam are combined into the steel chain block support beam 2 of the utility model. Moreover, the lower part of the cylindrical rail 211 is integrally arranged with the left side plate 21. Therefore, during the processing of the chain block support structure of the utility model, the chain block support beam 2 can be welded to the bed body 1 first, and then the cylindrical rail 211 and the support flat surface 221 can be processed by using a gantry machining center for one-time clamping. Therefore, the cylindrical rail 211 and the support flat surface 221 have high relative position accuracy, and the straightness of the cylindrical rail 211 and the support flat surface 221 is improved, thereby avoiding the error accumulation caused by the assembly of multiple parts through screws, improving the straightness of the chain block 99 on the chain block support beam 2, and improving the quality of the plate product. By arranging the oil injection nozzle 3 and the oil outlet hole 2111, lubricating oil can be input to the oil injection nozzle 3, and then input to the lower end of the oil outlet hole 2111. The lubricating oil fills the oil outlet hole 2111 and then overflows from the upper end of the oil outlet hole 2111 to the upper surface of the cylindrical rail 211, so that the circular arc groove 991 and the cylindrical rail 211 are lubricated by the lubricating oil, which avoids rapid wear of the circular arc groove 991 and accumulation of wear of the cylindrical rail 211, and improves the quality of the plate product. Since there are errors in the inner diameter and the cylindricality of the circular arc groove 991, and there are also errors in the outer diameter and the cylindricality of the cylindrical rail 211, when the circular arc groove 991 slides on the cylindrical rail 211, it is relatively easy to cause uneven friction. Some parts of the circular arc groove 991 and the cylindrical rail 211 may be in line contact, which increases the contact pressure between the circular arc groove 991 and the cylindrical rail 211 and enhances the friction effect. Therefore, by arranging the above lubricating structure, the service life of the cylindrical rail 211 is prolonged.

[0023] Further, as shown in FIG. 6, Figures 2 to 4As shown, the chain block support beam 2 is provided with a bridge plate 24, the bridge plate 24 is arranged between the upper portion of the right side plate 22 and the upper portion of the left side plate 21, the bridge plate 24 is arranged at the lower side of the groove cavity 20, and the bridge plate 24 is welded with the right side plate 22 and the left side plate 21 respectively, so that the right side plate 22 and the left side plate 21 are stably connected in a simple structure, and thus the chain block support beam 2 is actually a hollow structure, which is beneficial to reduce the use of materials and reduce the weight. As mentioned above, the chain block support beam 2 is arranged at the upper side of the bed body 1, and the lower end of the chain block support beam 2 is welded with the bed body 1, that is, the lower end of the right side plate 22 and the lower end of the left side plate 21 are welded with the bed body 1.

[0024] Further, as shown in Figures 2 to 4 , the chain block support beam 2 is provided with a web plate 23, the web plate 23 is arranged between the right side plate 22 and the left side plate 21, the upper end of the web plate 23 is welded with the bottom of the bridge plate 24, the left end of the web plate 23 is welded with the left side plate 21, and the right end of the web plate 23 is welded with the right side plate 22, that is, the web plate 23 is arranged vertically, since the web plate 23 connects the bridge plate 24, the left side plate 21 and the right side plate 22 at the same time, so as to facilitate the bridge plate 24 to keep perpendicular to the left side plate 21 and the right side plate 22, that is, to increase the rigidity of the chain block support beam 2, and the lower end of the web plate 23 can be flush with the lower end of the left side plate 21 (and the right side plate 22).

[0025] Further, as shown in Figure 3 , the web plate 23 is arranged along the front-rear direction, since the chain block support beam 2 is arranged along the front-rear direction, so that the chain block support beam 2 has better structural rigidity at each position in the extension direction.

[0026] Further, as shown in Figure 4 , the oil outlet hole 2111 is arranged along the diameter direction of the cylindrical rail 211, and the oil outlet hole 2111 is arranged vertically, in other words, the upper end of the oil outlet hole 2111 just penetrates the top end of the cylindrical rail 211, so that when the lubricating oil overflows to the surface of the cylindrical rail 211 through the upper end of the oil outlet hole 2111, the lubricating oil can be evenly distributed to the left and right sides (in the visual direction of Figure 4 ).
