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.

[0029] Example 1

[0030] like Figure 1-Figure 6 As shown;

[0031] A safe rubber mixer comprises a base 1.

[0032] In this embodiment: After checking the public (announcement) number: CN201721151000.7, a safe rubber mixer is disclosed. This technology discloses "a safe rubber mixer, including a mixing drum, a driving device and a handrail. The mixing drum is a hollow steel drum. The driving device includes a driving motor and a controller. The handrail includes two handrails. The handrail is connected to a brake switch and other technical contents. The safe rubber mixer can be provided with a handrail. The handrail is installed above the mixing drum, so that the operator can pause the equipment at any time when observing the mixed solid glue. The operation is convenient and very practical. At the same time, water is filled in the mixing drum to cool down and improve safety performance and other technical effects." Although the design can be provided with a handrail, a handrail is installed above the mixing drum, allowing the operator to pause the equipment at any time when observing the mixed solid rubber. However, in actual use, when the rubber passes through the two rollers, it is squeezed and crushed against each other, but this device does not have a protective device during squeezing, and the rollers cannot be operated in a sealed environment, which will cause the squeezed rubber to splash. The splashed rubber fragments will bring greater safety hazards and cause problems such as reduced rubber mixing efficiency. Combined with actual use, this problem is obviously a real problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, an adjustment component 2 and a collection component 3 are added to the application document.

[0033] In combination with the above content, in order to facilitate the mixing of rubber and avoid splashing of rubber during mixing, it also includes an adjusting component 2 installed on the surface of the base 1, and the adjusting component 2 includes a mixing box 21 installed on the surface of the base 1 and a buffer box 22 installed on the surface of the mixing box 21 and a feed hopper 23 installed on the surface of the buffer box 22.

[0034] In this embodiment: Based on this setting, when the rubber is extruded and mixed, two rollers are arranged inside the mixing box 21. The mixing box 21 can block the rubber squeezed by the rollers to a certain extent to prevent the squeezed rubber crumbs from splashing everywhere. The splashed rubber crumbs may cause harm to the operators. This can effectively protect the operators and make the rubber mixing safer. At the same time, when the rubber is added, it first passes through the feed hopper 23 and the buffer box 22. The feed hopper 23 and the buffer box 22 are connected to the mixing box 21, which can protect the through holes on the surface of the mixing box 21.

[0035] In an optional embodiment: the buffer box 22 is internally rotatably connected with a rotating rod 25, one end of the rotating rod 25 passes through the buffer box 22 and extends to one side of the buffer box 22, and is connected to the output shaft of a motor 24 installed on the surface of the buffer box 22, a collar 26 is installed on the outer surface of the rotating rod 25, a connecting rod 27 is installed on the outer surface of the collar 26, and a baffle 28 is installed on the end of the connecting rod 27 away from the collar 26.

[0036] In this embodiment: Based on this setting, the buffer box 22 can provide a certain buffer for the rubber added to the mixing box 21 to prevent the added rubber from accumulating inside the mixing box 21. A large amount of rubber accumulated inside the mixing box 21 will cause a load on the roller operation and damage the machine, thereby effectively improving the service life of the machine and making the operation of mixing the rubber smoother and safer. The buffer box 22 buffers the rubber by rotating the rotating rod 25 driven by the motor 24. The rotating rod 25 will rotate with four baffles 28 in a cycle. The baffles 28 can block the through holes on the surface of the buffer box 22 to a certain extent to control the flow rate of the rubber.

[0037] In an optional embodiment: a rotating shaft 201 is rotatably connected in a strip groove opened in the inner wall of the feed hopper 23, and a connecting ring 202 is symmetrically installed on the outer surface of the rotating shaft 201. The same sealing plate 29 is installed on the same side of the two connecting rings 202, and the sealing plate 29 is in contact with the inner wall of the feed hopper 23.

[0038] In the present embodiment: Based on this arrangement, two sealing plates 29 are symmetrically arranged inside the feed hopper 23. The two sealing plates 29 cooperate with each other to seal the feed hopper 23, so that the mixing box 21 can be realized as a sealed space, which can effectively prevent the dust generated during the rubber mixing from being discharged from the inside of the feed hopper 23 and affecting the operator. The two sealing plates 29 can drive the rotating shaft 201 to rotate on the inner wall of the feed hopper 23 through the connecting ring 202, so that when the rubber is added to the mixing box 21, the feed hopper 23 is in an open state.

[0039] In an optional embodiment: a boss 203 is installed on the inner wall of the feed hopper 23 , a tension spring 204 is installed on the bottom surface of the boss 203 , and one end of the tension spring 204 away from the boss 203 is connected to the sealing plate 29 .

[0040] In this embodiment: Based on this setting, by setting the tension spring 204, the tension spring 204 and the boss 203 can cooperate with each other, and the characteristics of the tension spring 204 itself can ensure that the two sealing plates 29 can continue to maintain a close seal. When rubber is added, the sealing plate 29 will be driven to rotate by the weight of the rubber itself, and at the same time, the tension spring 204 will be pulled to open the feed hopper 23, making it convenient for the rubber to enter the interior. After the rubber enters, the sealing plate 29 will return to its original position through the tension spring 204.

[0041] In combination with the above content, in order to facilitate the collection of dust generated when mixing rubber and prevent it from floating out and being inhaled by the operator, it also includes a collecting component 3 arranged on the surface of the base 1, and the collecting component 3 includes a collecting box 31 arranged on the surface of the base 1 and a connecting pipe 32 installed on the surface of the collecting box 31 and a filter screen 33 installed inside the collecting box 31. The end of the connecting pipe 32 away from the collecting box 31 is connected to the mixing box 21, and a fan 37 is installed on one side of the collecting box 31. The air intake of the fan 37 passes through the collecting box 31 and extends into the collecting box 31.

[0042] In this embodiment: Based on this setting, in order to collect the dust generated during rubber mixing, prevent the dust from floating in the mixing box 21 and affecting the rubber mixing, and prevent it from drifting into the external air and affecting the health of the operator, the dust is adsorbed by the fan 37, and the dust will be connected to the mixing box 21 through the connecting pipe 32, so that the dust falls into the collection box 31, and the filter net 33 blocks the dust to prevent the dust from entering the fan 37.

[0043] In an optional embodiment: a movable rod 34 is slidably connected to the surface of the collection box 31, one end of the movable rod 34 extends into the collection box 31 and is connected to a rubber protrusion 35 arranged in the collection box 31, and a spring 36 is sleeved on the outer surface of the movable rod 34, one end of the spring 36 abuts against the inner wall of the collection box 31, and the other end of the spring 36 abuts against the rubber protrusion 35.

[0044] In this embodiment: Based on this arrangement, in order to facilitate the removal of dust adsorbed on the surface of the filter 33, the rubber protrusion 35 connected to one end of the movable rod 34 is used to impact the filter 33, so that the filter 33 vibrates, and the dust on the surface of the filter 33 can be conveniently vibrated off. The impact of the rubber protrusion 35 on the filter 33 can be driven by pulling the movable rod 34 to drive the rubber protrusion 35 to compress the spring 36, and then release the spring 36 to restore and drive the rubber protrusion 35 to impact the filter 33. The operation is convenient. The rubber protrusion 35 is rubber-shaped, which can effectively protect the filter 33 and avoid damage caused by impact.

[0045] The working principle and use process of the utility model are as follows: when mixing rubber, in order to ensure the safety of production and avoid splashing of squeezed rubber, which may cause injury to workers, the rubber is added to the mixing box 21 for extrusion, and the debris is restricted by the mixing box 21. When the rubber is added to the mixing box 21, the rubber is first added from the feed hopper 23. When the rubber is added to the feed hopper 23, the two sealing plates 29 will be pressed downward by their own weight, and the two sealing plates 29 will respectively drive the rotating shaft 201 to rotate through the connecting ring 202, and at the same time, the two sealing plates 29 will be separated from each other, and the rubber can fall into the buffer box 22. After the rubber falls, the tension spring 204 will return to its original position, so that the two sealing plates 29 will contact each other to seal the feed hopper 23. When the rubber enters the buffer box 22, the motor 24 is started at the same time, and the motor 24 will drive the rotating rod 25 to rotate. The rotating rod 25 will drive the baffle 28 connected to one end of the four connecting rods 27 to rotate through the ring 26, and the baffle 28 will The through hole connected to the feed hopper 23 is blocked, so that the rate at which the rubber enters the buffer box 22 and the mixing box 21 can be controlled to prevent the rubber from accumulating in the mixing box 21 and causing the roller operation load. At the same time, by starting the fan 37, the fan 37 will absorb the dust generated by the rubber mixing, and the dust will fall into the collection box 31 through the connecting pipe 32. The filter 33 will protect the fan 37 to prevent the dust from entering the fan 37. At the same time, in order to remove the dust attached to the surface of the filter 33, the movable rod 34 can be pulled. The movable rod 34 will slide on the surface of the collection box 31, and the sliding will cooperate with the rubber protrusion 35 to compress the spring 36. When the movable rod 34 is released, the spring 36 will recover and drive the rubber protrusion 35 to move, so that the rubber protrusion 35 hits the filter 33, causing the dust attached to the surface of the filter 33 to fall off. This setting prevents debris from splashing, while avoiding the roller operation load and dust dispersion, greatly protecting the staff and making it safer.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
