Description

Technical Field

[0001] The utility model relates to the technical field of wooden cutlery, fork and spoon processing equipment, in particular to an automatic hot pressing machine for wooden cutlery, fork and spoon. Background Art

[0002] Disposable tableware (such as knives, spoons, forks, etc.) is mostly made of wood or bamboo. The usual processing method is to first cut the wood or bamboo into the shape of a spoon or fork, and then bend the head of the spoon or fork through a hot press to make it into the desired shape. The hot press includes an upper mold and a lower mold that are relatively set. The mold is opened and closed by driving the upper mold up and down. During each hot pressing, the sheet to be processed is first placed in the lower mold, and then the upper mold is pressed down. After a period of time, the upper mold rises, and then the finished product in the lower mold is taken out, and then the sheet to be processed is placed, and the above operation is continued. The following problems exist in the prior art:

[0003] Because the existing hot press machine needs to put the sheets into the lower mold one by one, and the staff can only wait for the hot pressing to be completed before loading, the loading speed is slow, which seriously affects the efficiency of the hot pressing. At the same time, the spoons and forks pressed by the existing hot press need to be grabbed by mechanical claws when discharging, and then conveyed to the conveyor belt for subsequent processing. However, since the number of spoons and forks formed by a single hot pressing is large, the number of claws of the mechanical claw must also be configured more, which increases the cost of hot pressing.

[0021] When hot pressing the wooden spoon and fork, the spoon and fork are filled in the several mold grooves 431 on the top of the lower mold box 42 and the lower mold box 43, and then the driving motor 12 is started to drive the threaded rod 13 to rotate in the slide groove 11, and the moving rod 15 is connected with the rotating motor box 41 to drive the lower mold box 43 to move until the infrared transmitter 44 and the infrared receiver 14 are docked, and then the driving motor 12 is stopped, and the lower mold box 43 can be just below the upper mold plate 34. After the hot pressing is completed, the driving motor 12 is started again to drive the threaded rod 13 to rotate, so that the lower mold box 43 moves to the left along the slide groove 11, and the lower mold box 42 moves to the right synchronously until the infrared transmitter 44 on the front side of the lower mold box 42 stops docking with the infrared receiver 14, and then the hot pressing operation is repeated, so that when the lower mold box 42 or the lower mold box 43 is hot pressed, the other one can be used to place the spoon and fork, thereby improving the hot pressing efficiency.

[0022] like Figure 3 As shown, the hot pressing mechanism 3 includes a fixed bracket 31, which is fixedly mounted on the top of the hot pressing platform 1, a parallel plate 32 is fixedly mounted on the front side of the fixed bracket 31, a hydraulic retractor 33 is fixedly mounted on the top of the parallel plate 32, the output end of the hydraulic retractor 33 passes through the bottom of the parallel plate 32 and is fixedly mounted with an upper mold plate 34, and four guide rods 35 are fixedly mounted in a rectangular array at the bottom of the upper mold plate 34;

[0023] By starting the hydraulic expander 33 on the top of the parallel plate 32, the upper mold plate 34 can be driven to move downward, so as to perform hot pressing on the spoon and fork in the mold groove 431 at the top of the lower mold box 43. The guide rod 35 plays a role of guiding and preventing dislocation during the hot pressing process.

[0024] like Figure 4 , Figure 5As shown, a bidirectional shaft motor 411 is fixedly installed in the inner cavity of the rotating motor box 41, and the left output shaft of the bidirectional shaft motor 411 passes through the left side of the rotating motor box 41 and is fixedly connected to the right side of the lower mold box 43, and the right output shaft of the bidirectional shaft motor 411 passes through the right side of the rotating motor box 41 and is fixedly connected to the left side of the lower mold box 1 42. A plurality of mold grooves 431 are provided on the top of the lower mold box 1 42 and the lower mold box 2 43, and four guide grooves 432 are provided in a rectangular array on the top of the lower mold box 1 42 and the lower mold box 2 43. The four guide grooves 432 are respectively located directly below the four guide rods 35, and an electric push rod 433 is fixedly installed on the bottom of the inner wall of the lower mold box 2 43, and the output end of the electric push rod 433 is fixedly installed There is a lifting plate 434, and a plurality of ejector rods 435 are evenly fixedly installed on the top of the lifting plate 434.

[0026] Let's talk about the working principle of the automatic heat press machine for wooden cutlery and spoon.

[0027] like Figure 1-5As shown, when the wooden spoon and fork are hot-pressed, the spoon and fork are filled in the lower mold box 1 42 and the plurality of mold grooves 431 on the top of the lower mold box 2 43, and then the threaded rod 13 is driven to rotate in the slide groove 11 by starting the driving motor 12, and the lower mold box 2 43 is driven to move by connecting the moving rod 15 with the rotating motor box 41, until the infrared transmitter 1 44 is docked with the infrared receiver 14, and the driving motor 12 is stopped, and the lower mold box 2 43 can be just below the upper mold plate 34, and the upper mold plate can be driven by starting the hydraulic expander 33 on the top of the parallel plate 32. The first mold box 42 is moved downward by the first mold 43, thereby hot pressing the spoon and fork in the mold groove 431 at the top of the second mold box 43. After completion, the driving motor 12 is started again to drive the threaded rod 13 to rotate, so that the second mold box 43 moves to the left along the slide groove 11, and the lower mold box 1 42 moves to the right synchronously until the infrared transmitter 144 on the front side of the lower mold box 1 42 is docked with the infrared receiver 14, and then the hot pressing operation is repeated. When the lower mold box 1 42 is hot pressed, the second mold box 43 is on the left side of the hot pressing platform 1. At this time, the bidirectional shaft motor 411 in the rotating motor box 41 can be started to drive the lower mold The tool box 43 rotates and flips, so that the spoon and fork in the mold groove 431 fall into the charging box 2 on the left and are collected. After flipping and resetting, the infrared receiver 45 and the infrared transmitter 46 are connected to each other, so that the lower mold box 1 42 and the lower mold box 2 43 are always kept parallel, and then the spoon and fork that have not been hot-pressed are put into the mold groove 431 at the top of the lower mold box 43 again, and then the output shaft of the driving motor 12 is reversed to reverse the threaded rod 13, so that the moving rod 15 drives the rotating motor box 41 to move to the right, so that the lower mold box 2 43 returns to the bottom of the upper mold plate 34, and the lower mold box 1 When the lower mold box 1 42 or the lower mold box 2 43 is flipped, since the internal structure of the lower mold box 1 42 and the lower mold box 2 43 is consistent, the electric push rod 433 will be started synchronously during the flipping, driving the lifting plate 434 to rise, and the top plate 436 located in the mold groove 431 connected by a plurality of push rods 435 can be used to push out the spoon and fork inside the mold groove 431, thereby preventing the spoon and fork from being stuck in the mold groove 431 during the flipping.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
