Description
Technical Field
[0001] This utility model relates to the technical field of raw material crushing devices, and in particular to a raw material crushing device for rubber strip production. Background Technology
[0002] Rubber strip production is a process that requires high standards for the physical state of raw materials. The performance of rubber strips largely depends on the uniformity of the raw materials. During the batching stage, the pulverized raw materials can be better mixed with other additives (such as vulcanizing agents and fillers). Taking vulcanized rubber strips as an example, uniformly pulverized raw materials can make the vulcanization reaction more complete and uniform, thereby improving the strength, wear resistance and other properties of the rubber strips.
[0003] Existing technologies, such as the utility model patent with publication number CN216605451U, disclose a raw material crushing and mixing device for rubber industry production. This patent uses a crushing shell with a discharge anti-blocking mechanism inside. The discharge anti-blocking mechanism includes a cavity located at the bottom of the crushing shell, a connecting groove on one side of the cavity, a connecting shaft inside the cavity, and an incomplete gear fixedly fitted on the outside of the connecting shaft. A rack is provided on one side of the incomplete gear. The beneficial effect of this raw material crushing and mixing device for rubber industry production is that the intermittent agitation of the moving strip in the discharge anti-blocking mechanism agitates the crushed rubber raw material discharged from the discharge port, preventing the crushed rubber raw material from clogging inside the discharge port during discharge. The rotation of the stirring blade accelerates the discharge speed of the crushed rubber raw material inside the discharge port, preventing rubber from accumulating inside the discharge port and causing blockage. This allows the crushed rubber raw material to be discharged quickly, thereby improving production efficiency and solving the problem of easy blockage at the discharge port when the crushed rubber raw material is discharged.
[0004] In the process of using crushing devices in daily life, there are problems. For example, the crushing devices mentioned above cannot adjust the size of the raw material outlet of the rubber strip. This means that different rubber strip products have different requirements for the raw material supply speed. For the production of some smaller rubber strip products, using too high a raw material supply speed will lead to insufficient dimensional accuracy of the extruded rubber strip. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the size of the raw material outlet for rubber strips. This results in different requirements for the raw material supply speed during the production of different rubber strip products. For the production of some smaller rubber strip products, using an excessively high raw material supply speed will lead to insufficient dimensional accuracy of the extruded rubber strips. Therefore, this invention proposes a raw material crushing device for rubber strip production.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a raw material crushing device for adhesive strip production, comprising a crushing tank, a foot support, and an adjusting component. The foot support is disposed on the lower surface of the crushing tank, and a crushing mechanism is disposed inside the crushing tank. A feeding port is provided on the upper surface of the crushing tank, and a discharge port is provided on the lower surface of the crushing tank. The adjusting component is disposed on the upper surface of the discharge port. The adjusting component includes a mounting frame. The mounting frame is fixedly connected to the outer arc surface of the crushing tank. A limit spring is fixedly connected to the inner wall of the mounting frame. A baffle is fixedly connected to the free end of the limit spring away from the limit spring. A connecting rod is fixedly connected to the side surface of the baffle. The side of the connecting rod away from the baffle is fixedly connected to a handle. A handle is fixedly connected to the side surface of the baffle. A limit hole is provided on the upper surface of the mounting frame.
[0007] Preferably, the surface of the pulverizing tank is provided with a sliding hole, and the baffle is slidably connected to the inner wall of the sliding hole. The size of the sliding hole matches that of the baffle. The baffle can block the discharge port to ensure that the rubber strip raw material is in a closed state during stirring.
[0008] Preferably, the connecting rod passes through the mounting frame, the surface of the mounting frame has a square hole, and the mounting frame is slidably connected to the inner wall of the square hole with a handle. The handle is C-shaped and can drive the baffle to adjust the size of the discharge port to ensure that the discharge port can be adapted to rubber strips of different sizes.
[0009] Preferably, the limiting hole penetrates the mounting frame, and there are multiple limiting holes. The multiple limiting holes are horizontally and evenly distributed about the mounting frame. The mounting frame can constrain the position of the limiting spring, so that the baffle can be directly reset when the discharge port needs to be closed.
[0010] Preferably, the upper surface of the mounting bracket is provided with a locking component, the locking component including a mounting block, the mounting block being fixedly connected to the side surface of the baffle, the upper surface of the mounting block having a mounting groove, the inner wall of the mounting groove being fixedly connected to a linkage spring, the end of the linkage spring away from the mounting block being fixedly connected to a linkage block, the inner wall of the mounting groove being fixedly connected to a pin, and the lower surface of the linkage block being fixedly connected to a positioning block. The linkage spring can constrain the position of the linkage block to ensure the accuracy of the locking position.
[0011] Preferably, the mounting block is fixedly connected to the side surface of the handle, the mounting block is in contact with the side surface of the mounting frame, the linkage spring is sleeved on the surface of the pin, the pin passes through the linkage block, there are two pins, the two pins are symmetrically arranged about the linkage block, the direction of movement of the linkage block can be guided by the pins to ensure that the linkage block moves in a vertical direction.
[0012] Preferably, the linkage block is in contact with the upper surface of the mounting block, the linkage block is in contact with the upper surface of the mounting bracket, and the positioning block is inserted into the inner wall of the limiting hole. Through the cooperation of the positioning block and the limiting hole, the position of the baffle can be locked, thereby further realizing the locking of the baffle.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting an adjustment component, when raw materials need to be crushed, the operator pours the raw materials into the crushing tank through the feeding port according to the proportion. After pouring is completed, the switch of the crushing mechanism is turned on, and the crushing mechanism is powered on to work and stir the raw materials in the crushing tank. After stirring is completed, when it is necessary to discharge the raw materials in the mixing tank, the switch of the crushing mechanism can be turned off, so that the crushing mechanism stops working. Subsequently, when it is necessary to adjust the size of the outlet according to the size of the corresponding rubber strip product, the operator holds the handle with one hand and pulls the handle outward. The handle is driven by force to drive the connecting rod. As the connecting rod and the handle move outward, the baffle moves outward at the same time. The baffle moves and compresses the limiting spring, and the limiting spring compresses... The deformation gradually exposes the discharge port through the baffle, allowing for control of the discharge port size. Once the appropriate discharge size is achieved, the movement stops. To close the discharge port, the operator releases the handle, releasing the pulling force on the baffle. This releases the pressure on the limit spring, causing the limit spring to rebound and reset, which in turn causes the connecting rod, handle, and baffle to rebound, thus blocking the discharge port again. By setting an adjustment component, the size of the discharge port can be effectively adjusted. In the extrusion process of rubber strips, the production of some small rubber strip products requires a lower raw material supply speed. In this case, the raw material outlet can be reduced to allow the raw material to enter the extruder slowly and steadily, thereby ensuring higher dimensional accuracy of the extruded rubber strips.
[0015] 2. In this utility model, by setting a locking component, when the position of the baffle needs to be adjusted, the operator can hold the linkage block with one hand and pull it upward. The linkage block moves upward under the guidance of the pin, pulling the linkage spring. The linkage spring deforms along the direction guided by the pin, thereby moving the positioning block away from the positioning hole. The positioning block no longer restricts the positioning hole, and the operator can adjust the size of the discharge port as described above. After the size of the discharge port is adjusted, the operator can release the hand holding the linkage block. The linkage spring loses its tension and resets, moving the linkage block downward along the pin. At the same time as the linkage block moves, the positioning block moves towards the positioning hole until the positioning block is reinserted into the positioning hole, thus locking the position of the baffle again. By setting a locking component, the position of the adjustment component can be effectively locked, so that the position of the baffle can be locked when the baffle is extruded according to different sizes of rubber strips, thereby further improving the stability of the rubber strip extrusion size.

Detailed Implementation
[0024] Please see Figures 1-6 This utility model provides a technical solution: a raw material crushing device for producing adhesive strips, including a crushing tank 1, a foot support 2 and an adjusting component 6.

[0025] The specific settings and functions of its adjustment component 6 and locking component 7 will be explained below.
[0026] In this embodiment: the adjustment component 6 includes a mounting bracket 61. The mounting bracket 61 is fixedly connected to the outer arc surface of the crushing tank 1. A limit spring 62 is fixedly connected to the inner wall of the mounting bracket 61. A baffle 63 is fixedly connected to the free end away from the limit spring 62. A connecting rod 64 is fixedly connected to the side surface of the baffle 63. The side of the connecting rod 64 away from the baffle 63 is fixedly connected to a handle 65. A handle 65 is fixedly connected to the side surface of the baffle 63. A limit hole 66 is opened on the upper surface of the mounting bracket 61.
[0027] Specifically, the surface of the pulverizing tank 1 is provided with a sliding hole, and the baffle 63 is slidably connected to the inner wall of the sliding hole, with the size of the sliding hole matching that of the baffle 63.
[0028] The effect achieved by the above components is that the discharge port 5 can be blocked by the baffle 63 to ensure that the rubber strip raw material is in a closed state during stirring.
[0029] Specifically, the connecting rod 64 passes through the mounting bracket 61, and a square hole is provided on the surface of the mounting bracket 61. A handle 65 is slidably connected to the inner wall of the mounting bracket 61 about the square hole, and the handle 65 is C-shaped.
[0030] The effect achieved by the above components is that the baffle 63 can be driven by the pull handle 65 to adjust the size of the discharge port 5, so as to ensure that the discharge port 5 can be adapted to rubber strips of different sizes.
[0031] Specifically, the limiting hole 66 penetrates the mounting bracket 61, and there are multiple limiting holes 66, which are horizontally and evenly distributed about the mounting bracket 61.
[0032] The effect achieved by the above components is that the position of the limiting spring 62 can be constrained by the mounting bracket 61, so that the baffle 63 can be directly reset when the discharge port 5 needs to be closed.
[0033] Specifically, the upper surface of the mounting bracket 61 is provided with a locking component 7, which includes a mounting block 71. The mounting block 71 is fixedly connected to the side surface of the baffle 63. The upper surface of the mounting block 71 is provided with a mounting groove 72. The inner wall of the mounting groove 72 is fixedly connected with a linkage spring 73. The end of the linkage spring 73 away from the mounting block 71 is fixedly connected with a linkage block 74. The inner wall of the mounting groove 72 is fixedly connected with a pin 75. The lower surface of the linkage block 74 is fixedly connected with a positioning block 76.
[0034] The effect achieved by the above components is that the position of the linkage block 74 can be constrained by the linkage spring 73 to ensure the accuracy of the locking position.
[0035] Specifically, the mounting block 71 is fixedly connected to the side surface of the handle 65, the mounting block 71 is in contact with the side surface of the mounting bracket 61, the linkage spring 73 is sleeved on the surface of the pin 75, the pin 75 passes through the linkage block 74, there are two pins 75, and the two pins 75 are arranged symmetrically about the linkage block 74.
[0036] The effect achieved by the above components is that the direction of movement of the linkage block 74 can be guided by the pin 75 to ensure that the linkage block 74 moves in a vertical direction.
[0037] Specifically, the linkage block 74 contacts the upper surface of the mounting block 71, the linkage block 74 contacts the upper surface of the mounting bracket 61, and the positioning block 76 is inserted into the inner wall of the limiting hole 66.
[0038] The effect achieved by the above components is that the position of the baffle 63 can be locked by the cooperation of the positioning block 76 and the limiting hole 66, thereby further realizing the locking of the baffle 63.
[0039] Working principle: When raw materials need to be crushed, the operator pours the raw materials into the crushing tank 1 through the feed port 4 according to the ratio. After pouring is complete, the switch of the crushing mechanism 3 is turned on, and the crushing mechanism 3 is powered on to stir the raw materials in the crushing tank 1. After stirring is complete, when it is necessary to discharge the raw materials from the mixing tank, the switch of the crushing mechanism 3 is turned off, so that the crushing mechanism 3 stops working. Subsequently, when it is necessary to adjust the size of the outlet according to the size of the corresponding rubber strip product, the operator holds the handle 65 with one hand and pulls the handle 65 outward. The handle 65 drives the connecting rod 64. As the connecting rod 64 and the handle 65 move outward, the baffle 63 moves outward at the same time. The baffle 63 moves and squeezes the limiting spring 62. The limiting spring 62 is squeezed and deformed, so that... The baffle 63 gradually exposes the discharge port 5, and then controls the size of the discharge port 5. Once the size of the discharge port 5 is adjusted to a suitable size, the movement can be stopped. If it is necessary to close the discharge port 5, the operator can release the hand holding the handle 65. The handle 65 loses the pulling force applied to the baffle 63, and the baffle 63 loses the pressure applied to the limit spring 62. Then the limit spring 62 rebounds and resets, causing the connecting rod 64, the handle 65 and the baffle 63 to rebound, thus blocking the discharge port 5 again. By setting the adjustment component 6, the size of the discharge port 5 can be effectively adjusted. In the rubber strip extrusion process, for the production of some small rubber strip products, a lower raw material supply speed is required. At this time, the raw material outlet can be reduced so that the raw material enters the extruder slowly and stably, thereby ensuring higher dimensional accuracy of the extruded rubber strip.
[0040] Additionally, by setting the locking component 7, when the position of the baffle 63 needs to be adjusted, the operator can hold the linkage block 74 with one hand and pull the linkage block 74 upward. The linkage block 74 moves upward under the guidance of the pin 75, pulling the linkage spring 73. The linkage spring 73 deforms along the guiding direction of the pin 75, thereby driving the positioning block 76 away from the positioning hole. The positioning block 76 no longer restricts the positioning hole, and the operator can then adjust the size of the discharge port 5 as described above. After the size of the discharge port 5 is adjusted, the operator can release the linkage block 7. When the spring 73 loses its tension, it resets and drives the linkage block 74 to move downward along the pin 75. As the linkage block 74 moves, the positioning block 76 moves towards the positioning hole until the positioning block 76 is reinserted into the positioning hole, thus re-locking the position of the baffle 63. By setting the locking component 7, the position of the adjusting component 6 can be effectively locked, so that the position of the baffle 63 can be locked when extruding rubber strips of different sizes, thereby further improving the stability of the rubber strip extrusion size.
