Description

Technical Field

[0001] The utility model relates to the technical field of foam raw material mixing, in particular to a novel raw material mixing device for foam production. Background Art

[0002] As we all know, foam plastics are materials made by foaming plastic particles, referred to as foam. Foams are divided into PU foam, EPE foam, CR foam, EVA foam, cross-linked polyethylene foam, SBR foam, EPDM foam, etc. The existing foams need to be mixed before production.

[0003] Traditional mixing equipment generally mixes materials through a group of mixing chambers. If the equipment has only one group of mixing chambers, then during the continuous production process, the newly added raw materials may be mixed with the old raw materials that are not completely mixed, resulting in unstable product quality. In addition, if the equipment needs to be shut down for cleaning or maintenance, the production schedule will also be affected, resulting in a decrease in production efficiency. Since continuous production cannot be carried out, the equipment is idle during the shutdown period, which is actually a waste of resources. At the same time, if uneven mixing leads to substandard product quality, then unqualified products are also a waste of resources. Utility Model Content

DETAILED DESCRIPTION

[0025] 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 in 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.

[0026] See also Figure 1-4 A novel raw material mixing equipment for foam production comprises a working box 1, a mixing chamber 2, a stirring device and an adjusting device. The interior of the working box 1 is symmetrically designed with two groups of the mixing chambers 2. The two groups of the mixing chambers 2 are both equipped with the stirring device. The stirring device comprises a stirring shaft 3 and a stirring rod 4. The stirring shaft 3 is rotatably installed in the mixing chamber 2. The outer wall of the stirring shaft 3 is equipped with the stirring rod 4. The bottom wall of the two groups of the stirring shafts 3 penetrates the bottom wall of the working box 1 and is equipped with a driven bevel gear 5. The two groups of the driven bevel gears 5 are meshed and connected with a group of active bevel gears 6. The end of the active bevel gear 6 is sleeved with a driving motor 7, and the driving motor 7 is adjusted and moved by the adjusting device. Support legs 8 are installed at the four corners of the bottom wall of the working box 1. Two groups of feeding hoppers 9 are respectively installed at the tops of the two groups of the mixing chambers 2. Two groups of discharging pipes 10 are respectively installed on the bottom walls of the two groups of the mixing chambers 2. In this embodiment, when in use, the foam raw material is first put into one of the groups through the feeding hopper 9. In the mixing chamber 2, the driving motor 7 is then driven by the adjusting device to drive the active bevel gear 6 to move to one side of the driven bevel gear 5 and mesh with it, and then the driving motor 7 is started, and the output end of the driving motor 7 drives the active bevel gear 6 to rotate, and the active bevel gear 6 drives the driven bevel gear 5 to rotate, and the driven bevel gear 5 drives the stirring shaft 3, and the stirring shaft 3 drives the stirring rod 4 to stir and mix the foam raw materials in the mixing chamber 2. After stirring and mixing, the rotation of the driving motor 7 is stopped, and then the driving motor 7 and the active bevel gear 6 are moved to the bottom of another group of mixing chambers 2 through the adjusting device, and meshed with the corresponding driven bevel gear 5, and then the mixed materials are discharged through the corresponding discharge pipe 10. At the same time of discharging, another group of mixing chambers 2 and the stirring device are used to cooperate with the driving motor 7 to stir and mix the foam raw materials. The two groups of mixing chambers 2 are used alternately to improve the utilization rate of the driving motor 7, make full use of the stirring capacity of the driving motor 7, improve the mixing efficiency, and avoid unnecessary energy waste.

[0027] In actual use, it is further convenient to adjust the movement of the drive motor 7. In this embodiment, the adjustment device includes an electric slide rail 11 and an electric slider 12. A support frame 13 is installed on the bottom wall of the work box 1. A groove body 14 is opened in the support frame 13. The electric slide rail 11 is installed in the groove body 14. The electric slider 12 is slidably installed on the electric slider 12. The side wall of the electric slider 12 is fixedly connected to the drive motor 7. The electric slider 12 moves linearly on the electric slide rail 11, driving the connected drive motor 7 and the active bevel gear 6 to move in the groove body 14, thereby realizing the linear movement adjustment of the drive motor 7.

[0028] During actual use, the movement of the electric slider 12 is further guided. In this embodiment, a fixed rod 15 is installed at one end of the support frame 13 away from the drive motor 7, and a guide block 16 is slidably installed on the fixed rod 15. One side of the guide block 16 is fixedly connected to the electric slider 12. During the movement and adjustment of the electric slider 12 on the electric slide rail 11, the guide block 16 drives the guide block 16 to slide on the fixed rod 15, which guides the movement of the electric slide rail 11 and prevents the electric slide rail 11 from deviating from the motion trajectory.

[0029] In actual use, it is further convenient to control the discharge of the discharge pipe 10. In this embodiment, a solenoid valve 17 is installed on the discharge pipe 10. The control valve can accurately control the flow of the discharge pipe 10 and adjust the pressure in the discharge pipe 10 to ensure that the material can flow out smoothly and prevent damage to the equipment due to excessive or insufficient pressure.

[0030] In actual use, in order to further facilitate the observation of the mixing situation in the mixing chamber 2, in this embodiment, two sets of observation windows 18 are provided on the front end face of the working box 1. The observation windows 18 can provide a clear line of sight, so that people can intuitively see the situation inside the mixing chamber 2, thereby facilitating monitoring and management.

[0031] In actual use, the stability and accuracy of the operation of the drive motor 7 are further guaranteed. In this embodiment, the drive motor 7 is a servo motor. The servo motor can control the position, speed and torque with high precision. The servo motor adopts closed-loop control and has good stability. It can avoid stalling, vibration and other problems, thereby ensuring the stability and accuracy of the operation of the drive motor 7.

[0032] In actual use, in order to further facilitate the control of the working status of various electrical components, in this embodiment, a controller 19 is installed on the working box 1, and the controller 19 is convenient for controlling the working status of various electrical components in the device.

[0033] In actual use, the shock-absorbing effect of the support leg 8 is further improved. In this embodiment, a shock-absorbing pad is installed on the bottom wall of the support leg 8. The shock-absorbing pad can effectively reduce the vibration generated by the working box 1 during operation, thereby extending its service life.
