Description

Technical Field

[0001] This utility model relates to the field of foaming machine equipment, specifically to a foaming mixing head nozzle cleaning device. Background Technology

[0002] After injection molding, residual material remains on the nozzle of the mixing head of the foaming machine. This residual material will affect the next injection molding. Therefore, the mixing head needs to be wiped after each injection molding to remove the residual material on the nozzle. Usually, the mixing head is driven by a robot to move the nozzle back and forth on the sponge layer to remove the residual material on the nozzle. There are disadvantages to removing the residual material by scraping the sponge layer: (1) The sponge layer needs to be replaced frequently, which affects the production rhythm; (2) It is not possible to remove the residual material on the nozzle very cleanly. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a foaming mixing head nozzle cleaning device that does not require frequent maintenance and can clean the residual material on the mixing head nozzle.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a foaming mixing head nozzle cleaning device, comprising: a frame, characterized in that: a vertical rotating shaft is provided on the frame, the rotating shaft is mounted on the frame via bearings, the rotating shaft can rotate and slide up and down on the frame via bearings, a cutter disc is provided at the top of the rotating shaft, the surface of the cutter disc is provided with cutting grooves that penetrate the cutter disc vertically, a motor is provided below the rotating shaft, the motor is mounted on a swing plate, the inner end of the swing plate is hinged to the frame, so that the swing plate can swing up and down with the motor, the output shaft of the motor is arranged upwards, and the motor output... The output shaft and the rotating shaft are connected by a universal coupling, enabling the motor to drive the rotating shaft to rotate. A pull-down crossbar is installed on the outer end of the swing plate, and an upper pull-up crossbar is installed on the frame above the pull-down crossbar. A spring is installed between the pull-down crossbar and the upper pull-up crossbar, with both ends of the spring connected to the pull-down crossbar and the upper pull-up crossbar respectively, so that the outer end of the swing plate can be elastically suspended, thereby allowing the cutter head to be elastically supported. When the mixing head nozzle is pressed onto the cutter head, the cutter head can elastically abut against the mixing head nozzle. After the cutter head rotates under the drive of the rotating shaft, the cutting groove on it can clean the material pressed onto the mixing head nozzle.

[0005] Furthermore, in the aforementioned foaming mixing head nozzle cleaning device, the opening of the blade groove gradually expands from the outside to the inside.

[0006] Furthermore, in the aforementioned foaming mixing head nozzle cleaning device, the blade groove is shaped like a magatama.

[0007] Furthermore, in the aforementioned foaming mixing head nozzle cleaning device, three blade grooves are provided and are evenly arranged around the center of the cutter disc.

[0008] Furthermore, in the aforementioned foaming mixing head nozzle cleaning device, the mounting structure between the cutter head and the rotating shaft includes: a cylinder, with a mounting plate arranged coaxially with the cylinder in the lower end of the cylinder, the mounting plate and the cylinder being fixed together by screws passing through the cylinder from the side and screwed into the side wall of the mounting plate, the mounting plate having open sides, and a mounting hole in the center of the mounting plate, the rotating shaft being fixed to the mounting plate through the mounting hole, the cutter head being fixed in the upper end of the cylinder, and the cutter head and the cylinder being fixed together by screws passing through the cylinder from the side and screwed into the side wall of the cutter head.

[0012] Figure 2 This is a three-dimensional structural diagram of the foaming mixing head nozzle cleaning device described in this utility model from another perspective. Detailed Implementation

[0013] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0014] like Figure 1 , Figure 2As shown, the foaming mixing head nozzle cleaning device includes: a frame 1, on which a vertical rotating shaft 2 is mounted, the rotating shaft 2 being mounted on the frame 1 via bearings, allowing the rotating shaft 2 to rotate and slide up and down on the frame 1 via bearings; a cutter head 3 is mounted on the top of the rotating shaft 2, with cutting grooves 4 extending vertically through the cutter head 3 on its surface; a motor 5 is mounted below the rotating shaft 2, the motor 5 being mounted on a swing plate 6, the inner end of the swing plate 6 being hinged to the frame 1, allowing the swing plate 6 to swing the motor 1 up and down; the output shaft of the motor 1 is arranged upwards, and the output shaft of the motor 1 is connected to the rotating shaft 2 via a universal coupling 7. The transmission is connected so that the motor 5 can drive the rotating shaft 2 to rotate. A pull-down crossbar 9 is provided on the outer end of the swing plate 6, and an upper pull-up crossbar 8 is provided on the frame 1 above the pull-down crossbar 9. A spring 10 is provided between the pull-down crossbar 9 and the upper pull-up crossbar 8. The two ends of the spring 10 are connected to the pull-down crossbar 9 and the upper pull-up crossbar 8 respectively, so that the outer end of the swing plate 6 can be elastically suspended, thereby allowing the cutter head 3 to be elastically supported. When the mixing head nozzle is pressed on the cutter head 3, the cutter head 3 can elastically abut against the mixing head nozzle. After the cutter head 3 is rotated under the drive of the rotating shaft 2, the blade groove 4 on it can clean the mixing head nozzle pressed on it.

[0015] During operation, the mixing head presses down on the corresponding position on the cutter head 3 according to the size of its nozzle. This corresponding position ensures that the nozzle does not insert into the blade groove 4, while also making full use of the groove opening of the blade groove 4 to scrape off the excess material on the nozzle. The larger the mixing head nozzle, the closer it is to the center of the cutter head 3.

[0016] In this embodiment, the opening of the cutting groove 4 gradually widens from the outside to the inside. The cutting groove 4 is shaped like a magatama, which allows for better scraping of excess material. There are three cutting grooves 4, which are evenly arranged around the center of the cutter head 3.

[0017] In addition, the mounting structure between the cutter head 3 and the rotating shaft 2 includes: a cylinder 11, with a mounting plate 12 arranged coaxially with the cylinder 11 in the lower port of the cylinder 11. The mounting plate 12 and the cylinder 11 are fixed together by screws passing through the cylinder 11 from the side and screwed into the side wall of the mounting plate 12. The sides of the mounting plate 12 are hollowed out for material discharge. A mounting hole is provided in the center of the mounting plate 12, and the rotating shaft 2 is fixed to the mounting plate 12 through the mounting hole. The cutter head 3 is fixed in the upper port of the cylinder 11, and the cutter head 3 and the cylinder 11 are fixed together by screws passing through the cylinder 11 from the side and screwed into the side wall of the cutter head 3. This arrangement is designed to prevent screws from being installed on the upper surface of the cutter head 3, keeping the upper surface of the cutter head 3 flat. It also ensures that the scrap material is blocked by the cylinder 11 and not thrown out, making it easier to collect the scrap material.

[0018] A vertical rod 13 is also installed on the frame 1, and a rotatable horizontal turntable 14 is installed at the top of the vertical rod 13. A sponge layer for cleaning the mixing head nozzle is laid on the upper surface of the horizontal turntable 14. When the cutter head 3 cannot be used to clean the residual material, the sponge layer on the upper surface of the horizontal turntable 14 can be used to temporarily clean the residual material on the nozzle. After the cutter head 3 is restored, the cutter head 3 will still be used to clean the residual material on the nozzle.
