Description

Technical Field

[0002] Demisting glue sprayer is a special glue spraying equipment. Its main function is to eliminate the mist generated in the glue spraying process through specific technical means while spraying adhesive, so as to improve the coating quality and workshop environment. This type of glue sprayer is widely used in industries with high requirements for coating technology such as automobile manufacturing, aerospace, and precision instruments. Demisting glue sprayer usually includes workbench, glue spraying system, demisting device, control system and other parts to ensure the accuracy of the spraying process and the cleanliness of the workshop air.

The traditional way of cleaning the glue spray head can only remove colloids with weak adhesion, which will still clog the glue spray head over time. Therefore, a demisting glue spray machine is needed to solve the existing shortcomings. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figure 1-7 As shown, the utility model provides a technical solution: a demisting glue spraying machine, comprising a workbench 1, a control mechanism 2 is fixedly connected to the top of the workbench 1, a control cylinder 3 is movably connected to the middle position of the control mechanism 2, an extension tube 4 is fixedly connected to the bottom end of the control cylinder 3, a glue spraying tube 5 is fixedly connected to the bottom end of the extension tube 4, a glue spraying head 6 is movably connected to the bottom end of the glue spraying tube 5, a limiting mechanism 7 is arranged on the outer side of the glue spraying tube 5, and the limiting mechanism 7 is movably connected to the glue spraying head 6, a switching mechanism 8 is fixedly connected to the outer side of the extension tube 4, and the bottom end of the switching mechanism 8 is fixedly connected to the bottom end of the extension tube 4. A receiving mechanism 9 is connected, and the receiving mechanism 9 is movably connected to the glue spray head 6. The control mechanism 2 includes a guide rail 201, a slider 202, a long rod 203 and a controller 204. The guide rail 201 and the slider 202 are symmetrically arranged. The bottom ends of the guide rails 201 are respectively fixedly connected to the two sides of the top of the workbench 1, the sliders 202 are respectively slidably connected to the top of the guide rails 201, the bottom ends of the long rods 203 are fixedly connected to the top of the sliders 202, the controller 204 is movably connected to the outside of the long rods 203, and the control tube 3 is movably connected to one side of the controller 204.

[0031] First, the guide rail 201 and the slider 202 can be used to control the long rod 203 at the top of the workbench 1, and the controller 204 can be used to drive the control cylinder 3 to move along the long rod 203, so as to realize the position movement of the glue spray head 6, and the glue spraying tube 5 can be used to realize the colloid spraying from the outlet of the glue spraying head 6. When the glue spraying head 6 needs to be replaced, the electric telescopic rod 805 is used to push the cross bar 806 downward to drive the horizontal plate 901 to move downward, and then the servo motor 1 804 is started to drive the gear 2 803 to rotate, so that the gear 1 802 rotates synchronously, thereby driving the cross bar 806 rotates. Since the top of the cross bar 806 is rotatably connected to the bottom end of the electric telescopic rod 805, the rotation of the cross bar 806 does not affect the state of the electric telescopic rod 805. The rotation of the cross bar 806 drives the horizontal plate 901 to rotate synchronously, so that the storage cylinder 903 rotates to the right below the glue spraying tube 5. Subsequently, the electromagnetic control ring 706 is used to make the telescopic column at its bottom move downward, so that the push ring 705 moves downward. Since the bottom end of the push ring 705 conflicts with the top inclined surface of the moving plate 701, the moving plates 701 move away from each other along the guide rod 703, so that The reset spring 702 is stretched and lengthened, so that the insertion rod 704 is separated from the socket 1 10 and the socket 2 11 respectively. At this time, the glue spray head 6 falls into the interior of the storage cylinder 903 due to its own gravity. Subsequently, the servo motor 2 906 is started to drive the screw 905 to rotate, so that the push plate 904 moves upward along the installation cylinder 902, and the glue spray head 6 inside the push rod installation cylinder 902 moves upward until the top glue spray head 6 conflicts with the bottom end of the glue spray tube 5, and the socket 10 and the socket 2 11 are connected, and the electromagnetic control ring 706 is operated in the reverse direction to make it extend and retract. The column moves upward, and under the action of the return spring 702, the movable plates 701 approach each other until the insertion rod 704 is inserted into the inside of the socket 10 and the socket 2 11, thereby fixing the new glue spray head 6 to the bottom end of the glue spray tube 5. Subsequently, the cross bar 806 is used to rotate the horizontal plate 901 so that the installation cylinder 902 is away from the bottom of the glue spray head 6, and the electric telescopic rod 805 is used to drive the horizontal plate 901 to rise upward, thereby preventing the installation cylinder 902 and the storage cylinder 903 from affecting the normal operation of the glue spray head 6, thereby completing the automatic replacement and storage of the glue spray head 6.

[0032] like Figure 1 and Figure 3As shown, the limiting mechanism 7 includes a moving plate 701, a return spring 702, a guide rod 703 and an insertion rod 704. The moving plate 701, the return spring 702, the guide rod 703 and the insertion rod 704 are all distributed in a circular array. The insertion rod 704 is fixedly connected to the bottom end of the moving plate 701, the guide rod 703 penetrates the moving plate 701, and the guide rod 703 is movably connected to the moving plate 701. The return spring 702 is sleeved on the outside of the guide rod 703, one end of the return spring 702 is fixedly connected to the outside of the glue spraying tube 5, and the other end of the return spring 702 is fixedly connected to the moving plate 7 01, the limiting mechanism 7 also includes a push ring 705 and an electromagnetic control ring 706. The push ring 705 is movably connected to the outside of the glue spraying tube 5, and the electromagnetic control ring 706 is fixedly connected to the outside of the glue spraying tube 5. The telescopic column at the bottom end of the electromagnetic control ring 706 conflicts with the top end of the push ring 705. The top end of the movable plate 701 is inclined, and the bottom end of the push ring 705 fits with the inclined surface of the movable plate 701. Several jacks 10 are provided on the outside of the glue spraying tube 5, and several jacks 2 11 are provided on the outside of the glue spraying head 6. The plug rods 704 are adapted to jacks 10 and 11.

[0033] The electromagnetic control ring 706 is utilized to make the telescopic column at its bottom move downward, so that the push ring 705 moves downward. Since the bottom end of the push ring 705 conflicts with the top inclined surface of the movable plate 701, the movable plates 701 move away from each other along the guide rod 703, so that the reset spring 702 stretches and becomes longer, thereby separating the insertion rod 704 from the socket 10 and the socket 2 11 respectively. At this time, the glue head 6 falls into the interior of the storage tube 903 due to its own gravity, which facilitates the effective fixation of the replaced glue head 6 to prevent it from falling off during use.

[0034] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the switching mechanism 8 includes a support plate 801, a gear 1 802, a gear 2 803, a servo motor 1 804, an electric telescopic rod 805 and a cross bar 806. The gear 1 802 and the gear 2 803 are both movably connected to the bottom end of the support plate 801 through a rotating shaft, and the gear 1 802 and the gear 2 803 are meshed. The servo motor 1 804 is fixedly connected to the top of the support plate 801, and the output end of the servo motor 1 804 is fixedly connected to the rotating shaft of the gear 2 803. The cross bar 806 runs through the gear 1 802 and its rotating shaft, and the cross bar 806 is movably connected to the gear 1 802 and its rotating shaft. The telescopic end of the electric telescopic rod 805 is rotatably connected to the top end of the cross bar 806. The extension tube 4 runs through the support plate 801, and the extension tube 4 is fixedly connected to the support plate 801. The top end of the electric telescopic rod 805 is fixedly connected to the outer side of the extension tube 4.

[0035] Start the servo motor 804 to drive the gear 2 803 to rotate, so that the gear 1 802 rotates synchronously, thereby driving the cross bar 806 to rotate. Since the top of the cross bar 806 is rotatably connected to the bottom end of the electric telescopic rod 805, the rotation of the cross bar 806 does not affect the state of the electric telescopic rod 805. The rotation of the cross bar 806 drives the horizontal plate 901 to rotate synchronously, so that the storage cylinder 903 rotates to the bottom of the glue spraying tube 5, which can control the position of the installation cylinder 902 and the storage cylinder 903 to avoid blocking the glue spraying head 6, which is conducive to installing the glue spraying head 6 and ensuring the normal operation of the glue spraying head 6.

[0036] like Figure 1 , Figure 4 , Figure 5 and Figure 6 As shown, the receiving mechanism 9 includes a horizontal plate 901, a mounting cylinder 902 and a storage cylinder 903. The mounting cylinder 902 is fixedly connected to one side of the horizontal plate 901, and the storage cylinder 903 is fixedly connected to the other side of the horizontal plate 901. The top of the horizontal plate 901 is fixedly connected to the bottom of the cross bar 806. The glue spray head 6 is respectively adapted to the inner side of the mounting cylinder 902 and the inner side of the storage cylinder 903. The receiving mechanism 9 includes a push plate 904, a screw rod 905 and a servo motor 906. The push plate 904 passes through the mounting cylinder 902, and the push plate 904 passes through the mounting cylinder 902. Plate 904 is movably connected to the mounting tube 902, the top of the push plate 904 fits with the bottom of the glue spray head 6, the bottom end of the screw 905 is movably connected to the outside of the mounting tube 902 through a rotating shaft, and the top of the screw 905 is movably connected to the inside of the cross plate 901 through a bearing, the servo motor 906 is fixedly connected to the top of the cross plate 901, and the output end of the servo motor 906 is fixedly connected to the top of the screw 905, the screw 905 passes through the push plate 904, and the screw 905 is threadedly connected to the push plate 904.

[0037] Start the servo motor 906 to drive the screw 905 to rotate, so that the push plate 904 moves upward along the installation tube 902, pushing the glue head 6 inside the installation tube 902 to move upward until the top glue head 6 conflicts with the bottom end of the glue tube 5, and the socket 1 10 and the socket 2 11 are connected, and the electromagnetic control ring 706 is operated in reverse to move its telescopic column upward. Under the action of the reset spring 702, the movable plates 701 are moved closer to each other until the rod 704 is inserted into the inside of the socket 1 10 and the socket 2 11, so that the new glue head 6 can be fixed to the bottom end of the glue tube 5, thereby realizing the replacement of the glue head 6 and facilitating the storage of the old glue head 6.

[0038] Working principle: When in use, first, the guide rail 201 and the slider 202 can be used to control the long rod 203 at the top of the workbench 1, and the controller 204 can be used to drive the control cylinder 3 to move along the long rod 203, so as to realize the position movement of the glue spray head 6, and the glue spraying tube 5 can be used to realize the colloid spraying from the outlet of the glue spraying head 6. When the glue spraying head 6 needs to be replaced, the electric telescopic rod 805 is used to push the cross bar 806 downward to drive the horizontal plate 901 to move downward, and then the servo motor 1 804 is started to drive the gear 2 803 to rotate, so that the gear 1 802 rotates synchronously. This drives the cross bar 806 to rotate. Since the top of the cross bar 806 is rotatably connected to the bottom end of the electric telescopic rod 805, the rotation of the cross bar 806 does not affect the state of the electric telescopic rod 805. The rotation of the cross bar 806 drives the horizontal plate 901 to rotate synchronously, so that the storage tube 903 rotates to the bottom of the glue spraying tube 5. Then, the electromagnetic control ring 706 is used to make the telescopic column at its bottom move downward, so that the push ring 705 moves downward. Since the bottom end of the push ring 705 conflicts with the top inclined surface of the moving plate 701, the moving plate 701 moves along the guide rod 703. The two ends of the rubber tube 904 are moved away from each other, so that the reset spring 702 is stretched and lengthened, so that the insertion rod 704 is separated from the socket 1 10 and the socket 2 11 respectively. At this time, the glue head 6 falls into the interior of the storage cylinder 903 due to its own gravity. Subsequently, the servo motor 2 906 is started to drive the screw 905 to rotate, so that the push plate 904 moves upward along the installation cylinder 902, and the glue head 6 inside the push rod installation cylinder 902 moves upward until the top glue head 6 conflicts with the bottom end of the glue hose 5, and the socket 10 and the socket 2 11 are connected. The electromagnetic control ring 706 is operated in the reverse direction to make Its telescopic column moves upward, and under the action of the return spring 702, the movable plates 701 approach each other until the insertion rod 704 is inserted into the inside of the socket 10 and the socket 2 11, thereby fixing the new glue spray head 6 to the bottom end of the glue spray tube 5. Subsequently, the cross bar 806 is used to rotate the horizontal plate 901 so that the installation cylinder 902 is away from the bottom of the glue spray head 6, and the electric telescopic rod 805 is used to drive the horizontal plate 901 to rise upward, thereby preventing the installation cylinder 902 and the storage cylinder 903 from affecting the normal operation of the glue spray head 6, thereby completing the automatic replacement and storage of the glue spray head 6.
