Description

Technical Field

[0001] This utility model belongs to the field of injection molding post-processing technology, and in particular relates to a hot melt machine for installing nuts. Background Technology

[0002] Injection molding is a plastic product molding process. In existing technologies, after injection molding, plastic products often require different post-processing steps depending on the situation, such as spray painting, screen printing, screw tightening, and nut insertion. Nut insertion involves hot-pressing a nut into the plastic product, and after cooling, the nut is fixed inside. The traditional hot-melt nut insertion process involves workers using metal tools to pre-press the nut into the cylindrical hole of the outer shell after injection molding, and then placing the shell on a hot-melt machine to heat-melt the nut into place. This hot-melt insertion method is purely manual, labor-intensive, and costly. Another method uses a nut hot-press insertion device to heat and insert the nut. However, existing nut hot-press insertion equipment on the market is incomplete in function. The workpiece installation station is located below the hot-press station, making operators susceptible to burns from the hot-pressed components or injuries from improper operation, leading to safety accidents. Utility Model Content

[0003] The purpose of this utility model is to provide a nut installation hot melt machine, which aims to solve the technical problem that the existing nut hot pressing implantation equipment on the market is not fully functional, the workpiece installation station is located below the hot pressing station, and when the operator installs the workpiece, he is easily burned by the hot pressing part of the hot pressing station, or is easily crushed due to improper operation, leading to safety accidents.

[0004] To achieve the above objectives, this utility model provides a nut hot-melt installation machine, including a base, a worktable on the base, and a nut hot-melt installation device on the worktable. The nut hot-melt installation device includes an installation mechanism, a hot-pressing mechanism, and a nut feeding mechanism. The installation mechanism is slidably mounted on the worktable and is used to install workpieces. The nut feeding mechanism is mounted on the worktable and located above the hot-pressing mechanism. The nut feeding mechanism is used to feed nuts onto the hot-pressing mechanism. The hot-pressing mechanism is mounted on the worktable and is used to heat the nuts and hot-press them onto the workpiece of the installation mechanism.

[0005] Furthermore, the installation mechanism includes a slide rail, an installation fixture, and a push cylinder. The slide rail is mounted on the worktable, with one end positioned below the hot pressing mechanism. The installation fixture is slidably mounted on the slide rail. The push cylinder is mounted on the worktable, with its drive end connected to the installation fixture. The push cylinder is used to drive the installation fixture to slide on the slide rail.

[0006] Furthermore, the hot pressing mechanism includes a hot pressing head and a linear module. The linear module is mounted on the worktable and positioned on one side of the slide rail. The hot pressing head is located at the drive end of the linear module, which drives the hot pressing head to move vertically towards or away from the slide rail. A nut feeding mechanism is connected to the hot pressing head and is used to feed nuts into the hot pressing head.

[0007] Furthermore, the hot pressing mechanism also includes a height adjustment mechanism, which comprises an adjustment seat, guide columns, and threaded columns. The adjustment seat is mounted on the worktable, and the guide columns and threaded columns are mounted parallel to each other on the adjustment seat, with the guide columns perpendicular to the slide rails. An adjustment plate is provided on one side of the linear module, with guide holes that slide with the guide columns and threaded holes that thread with the threaded columns.

[0008] Furthermore, the hot press head includes a hot press base and a hot press block. The hot press base is connected to the linear module, and the hot press block is located at the lower end of the hot press base, facing the mounting mechanism. The hot press block has several heating holes for installing heating tubes, and the upper end of the hot press block also has a material storage hole, which is connected to the nut feeding mechanism and is used to store nuts.

[0009] Furthermore, the nut feeding mechanism includes a vibratory feeder and a feeding tube. One end of the feeding tube is connected to the vibratory feeder, and the other end is connected to the storage hole. The vibratory feeder is used to transport the nuts along the feeding tube into the storage hole.

[0010] Furthermore, the hot press block is also provided with a pressing hole, which is located at the lower end of the hot press block. The hot press block is also provided with a material passage, which connects the storage hole and the pressing hole. A pusher cylinder is also provided on one side of the hot press block. The pusher cylinder is used to drive the nut located in the storage hole to move along the material passage to the pressing hole.

[0011] The above-mentioned technical solutions of one or more of the nut installation hot melt machines provided in this utility model embodiment have at least one of the following technical effects: The installation mechanism is moved away from the hot pressing mechanism, and then the workpiece to be hot pressed is installed in the installation mechanism. During the installation process, the nut feeding mechanism transports the nut to the hot pressing mechanism, which preheats the nut. After installation, the installation mechanism is pushed below the hot pressing mechanism, and then the hot pressing mechanism moves to hot press the heated nut into the workpiece, completing the nut insertion. During the installation process, the installation mechanism can be kept away from the hot pressing mechanism, avoiding accidental contact with the hot pressing mechanism and resulting in burns. It also avoids accidental operation of the hot pressing mechanism, which could injure the operator. The nut feeding mechanism transports the nut to the hot pressing mechanism for heating, greatly saving the nut heating time and improving production efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0021] In one embodiment of this utility model, reference is made to Figures 1-3 As shown, a nut hot-melt mounting machine is provided, including a base 100, a worktable 110 on the base 100, and a nut hot-melt mounting device 120 on the worktable 110. The nut hot-melt mounting device 120 includes a mounting mechanism 200, a hot-pressing mechanism 300, and a nut feeding mechanism 400. The mounting mechanism 200 is slidably mounted on the worktable 110 and is used to mount workpieces. The nut feeding mechanism 400 is mounted on the worktable 110 and is located above the hot-pressing mechanism 300. The nut feeding mechanism 400 is used to feed nuts onto the hot-pressing mechanism 300. The hot-pressing mechanism 300 is mounted on the worktable 110 and is used to heat the nuts and hot-press them onto the workpiece of the mounting mechanism 200. In this embodiment, the installation mechanism 200 is moved away from the hot pressing mechanism 300. The workpiece to be hot-pressed is then placed in the installation mechanism 200. During installation, the nut feeding mechanism 400 transports the nut to the hot pressing mechanism 300, which preheats the nut. After installation, the installation mechanism 200 is pushed below the hot pressing mechanism 300, which then moves to hot-press the heated nut into the workpiece, completing the nut insertion. During installation, the installation mechanism 200 is kept away from the hot pressing mechanism 300, preventing accidental contact and burns, and also preventing accidental operation that could injure operators. The nut feeding mechanism 400 transports the nut to the hot pressing mechanism 300 for heating, significantly reducing heating time and improving production efficiency.

[0022] Specifically, refer to Figures 1-3As shown, the mounting mechanism 200 includes a slide rail 210, a mounting fixture 220, and a push cylinder 230. The slide rail 210 is mounted on the worktable 110, with one end positioned below the hot pressing mechanism 300. The mounting fixture 220 is slidably mounted on the slide rail 210. The push cylinder 230 is mounted on the worktable 110, and its drive end is connected to the mounting fixture 220. The push cylinder 230 is used to drive the mounting fixture 220 to slide on the slide rail 210. In this embodiment, the slide rail 210 restricts the movement direction of the mounting fixture 220, while the cylinder 230 drives the mounting fixture 220 to slide along the slide rail 210. The rest points of the mounting fixture 220 are at both ends of the slide rail 210, so that the mounting fixture 220 moves to the same position after each workpiece is installed, and the workpiece is installed in the mounting fixture 220. The mounting fixture 220 positions the workpiece to avoid deviation in the position of the mounting fixture 220, which would cause the nut to be pressed in at a different position and affect the yield.

[0023] Specifically, refer to Figures 1-3 As shown, the hot pressing mechanism 300 includes a hot pressing head 310 and a linear module 320. The linear module 320 is mounted on the worktable 110 and is located on one side of the slide rail 210. The hot pressing head 310 is located at the driving end of the linear module 320, which drives the hot pressing head 310 to move vertically towards or away from the slide rail 210. A nut feeding mechanism 400 is connected to the hot pressing head 310 and is used to feed nuts into the hot pressing head 310. In this embodiment, the linear module 320 drives the hot pressing head 310 to move vertically, ensuring that the position of the hot pressing head 310 is consistent each time, thus guaranteeing that the height and position of the nut are consistent when it is hot-pressed into the workpiece, thereby improving the yield rate.

[0024] Specifically, refer to Figures 1-3 As shown, the hot pressing mechanism 300 also includes a height adjustment mechanism 500, which includes an adjustment seat 510, a guide post 520, and a threaded post 530. The adjustment seat 510 is mounted on the worktable 110, and the guide post 520 and the threaded post 530 are mounted parallel to each other on the adjustment seat 510, with the guide post 520 perpendicular to the slide rail 210. An adjustment plate 321 is provided on one side of the linear module 320. The adjustment plate 321 has a guide hole 322 that slides with the guide post 520 and a threaded hole 323 that is threaded with the threaded post 530. In this embodiment, by rotating the threaded post 530, the linear module 320 moves along the direction of the guide post 520, thereby adjusting the height of the linear module 320 to accommodate workpieces requiring different hot pressing heights.

[0025] Specifically, refer to Figures 1-3As shown, the hot press head 310 includes a hot press base 311 and a hot press block 312. The hot press base 311 is connected to the linear module 320, and the hot press block 312 is disposed at the lower end of the hot press base 311, with the hot press block 312 facing the mounting mechanism 200. The hot press block 312 is provided with a plurality of heating holes 313 for mounting heating tubes, and the upper end of the hot press block 312 is also provided with a material storage hole 314, which is connected to the nut feeding mechanism 400 and is used to store nuts. In this embodiment, a heating tube is installed in the heating hole 313 to heat the hot pressing block 312. The nut feeding mechanism 400 feeds the nuts into the storage hole 314, which contains multiple nuts. The nuts are heated by the heating tube in the storage hole 314 to reach a predetermined temperature. Then, the hot pressing block 312 hot presses the workpiece to press the nuts into the workpiece. Placing multiple nuts into the storage hole 314 for heating can greatly reduce the heating time of the nuts and improve the processing speed.

[0026] Specifically, refer to Figures 1-3 As shown, the nut feeding mechanism 400 includes a vibratory feeder 410 and a feeding pipe 420. One end of the feeding pipe 420 is connected to the vibratory feeder 410, and the other end is connected to a storage hole 314. The vibratory feeder 410 is used to transport nuts along the feeding pipe 420 into the storage hole 314. In this embodiment, the vibratory feeder 410 sorts and positions the nuts and transports them to the feeding pipe 420. In the feeding pipe 420, due to their own weight, the nuts fall into the storage hole 314 for preheating, reducing the heating time and increasing the processing speed.

[0027] Specifically, refer to Figures 1-3 As shown, the hot pressing block 312 is also provided with a pressing hole 315, which is located at the lower end of the hot pressing block 312. The hot pressing block 312 is also provided with a material passage 316, which connects the storage hole 314 and the pressing hole 315. A pusher cylinder 317 is also provided on one side of the hot pressing block 312. The pusher cylinder 317 is used to drive the nut located in the storage hole 314 to move along the material passage 316 into the pressing hole 315. In this embodiment, the pusher cylinder 317 is used to push one of the nuts in the storage hole 314 into the pressing hole 315 along the material passage 316, and at the same time abut against the nut, so that the nut is located in the pressing hole 315. Then, the linear module 320 drives the hot pressing head 310 to descend and hot press the workpiece, so that the nuts can be pressed into the workpiece one by one, avoiding two nuts falling on the workpiece at the same time, which would affect the yield of the processed product.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
