Description

Technical Field

[0001] The utility model relates to the technical field of heating platens for hot melt glue machines, and particularly relates to a heating platen for a platen-type hot melt glue machine. Background Technique

[0002] A platen-type hot melt glue machine is a device used for hot melt glue bonding. It heats the glue rod and coats it on the surface of the object to be bonded, and then uses a platen to press two objects together, so that the molten glue solidifies and forms a firm bond. When the platen in the existing platen-type hot melt glue machine is in use, the staff needs to manually apply butter on the outside of the platen, so as to reduce the friction between the sealing ring and the glue barrel during the downward pressing of the platen and make the downward pressing smoother. However, during the work, the staff often forgets to apply butter, or the butter and the inside of the glue barrel are exhausted, which will cause the platen to rub against the glue barrel, reduce the smoothness of the platen during downward pressing, and at the same time reduce the service life of the platen through friction. Content of the Utility Model

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a technical solution. Please refer to Figure 1 and Figure 2 , a heating pressure plate for a pressure plate type hot melt adhesive machine, including: a pressure plate group 1, a flange 2, a heater group 3 and a pipeline 4. The flange 2 can facilitate the connection between the pressure plate group 1 and an external hydraulic press, and the pipeline 4 facilitates the connection between the pressure plate group 1 and an external gear pump. The heater group 3 is connected to the top of the pressure plate group 1 through a groove, and the heater group 3 is connected to an external temperature controller through a wire. The heater group 3 can heat the pressure plate group 1 to melt the solid glue inside the glue bucket.

[0023] This solution is a structural improvement to the non-electronic component part based on the existing heating pressure plate. Among them, the pressure plate group 1, the flange 2, the heater group 3 and the pipeline 4 are common heating pressure plate products that have been popularized in the existing technology. The flange 2 is connected to the top of the pressure plate group 1, the heater group 3 is installed on the top of the pressure plate group 1, the pipeline 4 is installed on the left side of the top of the pressure plate group 1, and a lubrication mechanism 5 is slidably connected to the outside of the pressure plate group 1.

[0024] Please refer to Figure 3 and Figure 4 , the lubrication mechanism 5 includes a slotted ring 51. The slotted ring 51 can connect the piston 52. The inside of the slotted ring 51 is equally spaced with notches 511, and the notches 511 are slidably connected to the piston 52. The notches 511 are communicated with the brush hair 57 and the short pipe 54. The notches 511 facilitate the connection of the piston 52, the brush hair 57 and the short pipe 54. The slotted ring 51 is slidably connected to the pressure plate group 1.

[0025] The inside of the slotted ring 51 is slidably connected with pistons 52 at equal intervals. The movement of the piston 52 inside the slotted ring 51 can squeeze out the butter. A guide plate 521 is embedded in the inside of the piston 52, and the guide plate 521 is slidably connected to the slot 511. The guide plate 521 can make the piston 52 move linearly inside the slot 511. The end of the piston 52 close to the pressure plate group 1 is fixedly connected with a conical block 53. The top and bottom of the conical block 53 are both inclined surfaces, which facilitates the driving movement of the pressure plate group 1 when it is raised or lowered.

[0026] The interior of the slotted ring 51 is connected with short tubes 54 at equal intervals. The short tubes 54 cooperate with the one-way valve 55 to ensure that the butter in the oil box 56 can only enter the interior of the slot 511 in one direction, and the butter in the slot 511 cannot flow back to the interior of the oil box 56. The outside of the short tube 54 is connected with the one-way valve 55. The top of the short tube 54 is connected with the oil box 56. The top of the oil box 56 is penetrated by a feed port 561, and a plug is embedded in the feed port 561. The feed port 561 is convenient for the staff to replenish lubricating butter to the interior of the oil box 56.

[0027] The bottom of the oil box 56 is connected to the top of the slotted ring 51 by bolts, and the interior of the oil box 56 is filled with lubricating butter. The oil box 56 can be disassembled and maintained from the top of the slotted ring 51. The outside of the slotted ring 51 is evenly connected with bristles 57, and the bristles 57 can spread butter on the outside of the pressure plate group 1. The end of the piston 52 away from the pressure plate group 1 is fixedly connected with a spring 58, and the spring 58 can drive the piston 52 to return after movement. The spring 58 is connected to the inside of the slotted ring 51.

[0028] This solution first connects the flange 2 to the hydraulic system on the frame, connects the pipeline 4 to the gear pump outside the frame, connects the heater group 3 to the external temperature control system, connects the lubrication mechanism 5 to the inner top of the frame through the external curved arm, drives the pressure plate group 1 to descend, and prepares to be inserted into the inside of the rubber barrel. At the same time, the pressure plate group 1 will resist the conical block 53, and then the conical block 53 will retract to the inside of the notch 511, and drive the piston 52 to move, and at the same time generate pressure, squeeze the butter inside the notch 511 to the outside of the bristles 57, and when the pressure plate group 1 passes the bristles 57, the bristles 57 will smear the butter on the outside of the pressure plate group 1;

[0029] After the pressure plate assembly 1 passes through the conical block 53, the conical block 53 returns to its original position through the spring 58, and negative pressure is generated at this time. The negative pressure cooperates with the short tube 54 and the one-way valve 55 to suck the butter inside the oil box 56 into the groove 511 for subsequent use;

[0030] When the pressure plate group 1 is in use, it automatically applies lubricating grease to the outside of the pressure plate group 1 by squeezing and driving the added lubricating mechanism 5, without the need for manual application by the staff. Subsequently, the friction between the pressure plate group 1 and the glue bucket is reduced, making the downward pressing smoother. At the same time, wear caused by friction is avoided, thereby increasing the service life of the pressure plate group 1. Also, after the pressure plate group 1 moves, the lubricating mechanism 5 can automatically replenish the grease, without the need for the staff to manually add grease into the notch 511, thereby increasing the overall automation of the lubricating mechanism 5.
