Description

Technical Field

[0001] This utility model belongs to the technical field of protective mechanisms, and in particular relates to a protective mechanism for a roller press. Background Technology

[0002] A roller press protective mechanism is a specialized device designed to address the safety hazards posed by the lack of protective devices during the rolling process of existing roller presses. It is typically composed of specific materials and structures and effectively prevents the rolled object from splashing outwards during roller press operation. When the roller press is performing rolling operations, this protective mechanism provides reliable safety for operators, preventing serious injury from splashed objects, greatly improving the safety of roller press operation and creating favorable conditions for smooth production.

[0003] Existing roller presses have a significant problem in the actual process of rolling various items: due to the lack of a dedicated and effective protective mechanism, when the roller press is in operation and rolling items, the rolled objects are very likely to fly out uncontrollably in all directions under the strong pressure. If someone is operating the machine at this time, these flying objects will rush towards the person at extremely high speed, posing a great threat to the operator's life safety and seriously affecting workplace safety and the smooth progress of production. Utility Model Content

[0004] The purpose of this utility model is to provide a protective mechanism for a roller press. By providing a protective mechanism, the problem is solved where, in the absence of a dedicated and effective protective mechanism, when the roller press is in operation and pressing items, the objects being pressed are likely to fly out uncontrollably under the strong pressure. If someone is operating the machine at this time, these flying objects will rush towards the person at a very high speed, posing a great threat to the life safety of the operator and seriously affecting the safety of the workplace and the smooth progress of production.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a protective mechanism for a roller press, including a feed hopper and a protective mechanism and a configuration mechanism disposed on the feed hopper;

[0007] The protective mechanism includes protective doors hinged to the inner walls of the front and rear ends of the feed hopper. The bottom of each of the two protective doors is fixedly connected to a fixing block 1. The inner walls of the front and rear ends of the feed hopper are fixedly connected to a fixing block 2. The tops of each of the two fixing blocks 2 are fixedly connected to two dampers. The tops of several dampers are fixedly connected to two fixing blocks 1. The outer walls of several dampers are wound with springs 1. One end of several springs 1 is fixedly connected to two fixing blocks 1, and the other end of several springs 1 is fixedly connected to two fixing blocks 2.

[0008] Furthermore, an inclined plate is fixedly connected to the inner wall of the front end of the feed hopper, and an inclined plate is fixedly connected to the inner wall of the rear end of the feed hopper. Both the inclined plate and the inclined plate are adapted to the feed hopper.

[0009] Furthermore, the configuration mechanism includes two fixing components and a dust collection component. The fixing components include a roller press disposed at the bottom of the feed hopper. An L-shaped plate is fixedly connected to the front of the feed hopper. The bottom of the L-shaped plate is in contact with the roller press. An installation groove is provided on the L-shaped plate. Two sliding rods are fixedly connected to the inner wall of the installation groove. A clamping plate is slidably sleeved on the outer wall of the two sliding rods. The back of the clamping plate is in contact with the roller press.

[0010] Furthermore, the outer walls of both slide rods are wound with springs, one end of each spring is fixedly connected to a mounting groove, and the other end of each spring is fixedly connected to a clamping plate.

[0011] Furthermore, the dust collection assembly includes a support frame fixedly connected to the right side of the feed hopper, a collection box slidably connected to the inner wall of the support frame, a through hole on the left inner wall of the collection box, all of which communicate with the feed hopper and the support frame, and a plurality of filter holes on the right inner wall of the collection box.

[0012] Furthermore, a negative pressure chamber is fixedly connected to the right side of the support frame, a support rod is fixedly connected to the inner wall of the negative pressure chamber, a motor is fixedly connected to the support rod, a rotating shaft is fixedly connected to the output end of the motor, and fan blades are fixedly sleeved on the outer wall of the rotating shaft.

[0013] Furthermore, a filter plate is fixedly connected to the inner wall of the negative pressure chamber, and the filter plate is connected to the negative pressure chamber, the collection box and the feed hopper.

[0014] This utility model has the following beneficial effects:

[0015] (1) By setting up a protective mechanism, the object to be rolled can be put into the feed hopper during use. Due to the weight of the object itself, it will press down the two protective doors hinged on the feed hopper. During the pressing process, the damper and spring on the back of the protective door will be compressed synchronously. When the protective door is no longer pressed by the heavy object, the two protective doors will be reset under the pushing action of spring. At the same time, the inclined plate 1 and inclined plate 2 in the feed hopper cooperate with each other to make the object entering the feed hopper flow evenly into the roller press for rolling. In addition, through the special design of inclined plate 1 and inclined plate 2, some of the splashed objects can also be blocked. Through this setting, it can effectively prevent the object from splashing out uncontrollably in all directions under strong pressure, thereby greatly improving the safety during operation.

[0016] (2) By setting up a configuration mechanism, when it is necessary to install the feed hopper on the roller press, the feed hopper can be temporarily placed on the roller press first. Then, the clamping plate on the L-shaped plate is pulled outward. During the pulling process, the clamping plate will slide outward on the outer wall of the two slide rods, and at the same time, the spring on the outer wall of the slide rods will be compressed. Through this operation, the feed hopper can be correctly placed on the top of the roller press. After it is placed, the two clamping plates are released. At this time, the two clamping plates will be pushed by the spring on them, so that the feed hopper can be fixed to the roller press. Through this setting, the cumbersome installation process can be reduced, thereby improving the installation efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 As shown, this utility model is a roller press protection mechanism, including a feed hopper 1 and a protection mechanism 2 and a configuration mechanism 3 disposed on the feed hopper 1;

[0028] The protective mechanism 2 includes protective doors 21 that are hinged to the inner walls of the front and rear ends of the feed hopper 1. The bottom of each of the two protective doors 21 is fixedly connected to a fixing block 22. The inner walls of the front and rear ends of the feed hopper 1 are fixedly connected to a fixing block 23. The tops of each of the two fixing blocks 23 are fixedly connected to two dampers 24. The tops of several dampers 24 are fixedly connected to the two fixing blocks 22. The outer walls of several dampers 24 are wrapped with springs 25. One end of several springs 25 is fixedly connected to the two fixing blocks 22, and the other end of several springs 25 is fixedly connected to the two fixing blocks 23.

[0029] An inclined plate 26 is fixedly connected to the inner wall of the front end of the feed hopper 1, and an inclined plate 27 is fixedly connected to the inner wall of the rear end of the feed hopper 1. Both the inclined plate 26 and the inclined plate 27 are adapted to the feed hopper 1.

[0030] By cooperating with the inclined plates 26 and 27 inside the feed hopper 1, the objects entering the feed hopper 1 can flow evenly into the roller press 31 for rolling. Furthermore, the special design of the inclined plates 26 and 27 can also block some of the splashed objects.

[0031] The configuration mechanism 3 includes two fixing components and a dust collection component. The fixing components include a roller press 31 set at the bottom of the feed hopper 1. An L-shaped plate 32 is fixedly connected to the front of the feed hopper 1. The bottom of the L-shaped plate 32 is in contact with the roller press 31. An installation groove 33 is opened on the L-shaped plate 32. Two sliding rods 34 are fixedly connected to the inner wall of the installation groove 33. A clamping plate 35 is slidably sleeved on the outer wall of the two sliding rods 34. The back of the clamping plate 35 is in contact with the roller press 31.

[0032] By pulling the clamping plate 35 on the L-shaped plate 32 outward, the clamping plate 35 will slide outward on the outer wall of the two slide rods 34 during the pulling process, and at the same time, the spring 36 on the outer wall of the slide rods 34 will be compressed. Through this operation, the feed hopper 1 can be correctly placed on the top of the roller press 31.

[0033] The outer walls of both slide rods 34 are wrapped with springs 36. One end of each spring 36 is fixedly connected to the mounting groove 33, and the other end of the spring 36 is fixedly connected to the clamping plate 35.

[0034] By loosening the two clamping plates 35, the two clamping plates 35 will be pushed by the springs 36 on them, so that the feed hopper 1 can be fixed to the roller press 31, thereby reducing the cumbersome installation process and improving installation efficiency.

[0035] The dust collection assembly includes a support frame 37 fixedly connected to the right side of the feed hopper 1. A collection box 38 is slidably connected to the inner wall of the support frame 37. A through hole 39 is opened on the left inner wall of the collection box 38. The through holes 39 communicate with the feed hopper 1 and the support frame 37. A number of filter holes 391 are opened on the right inner wall of the collection box 38.

[0036] The filter hole 391 creates suction in the collection box 38, which can adsorb the dust floating in the feed hopper 1 and collect it in the collection box 38. When the collection box 38 needs to be cleaned, simply pull the collection box 38 outward to remove it for easy cleaning.

[0037] A negative pressure chamber 392 is fixedly connected to the right side of the support frame 37. A support rod 393 is fixedly connected to the inner wall of the negative pressure chamber 392. A motor 394 is fixedly connected to the support rod 393. A rotating shaft 395 is fixedly connected to the output end of the motor 394. A fan blade 396 is fixedly sleeved on the outer wall of the rotating shaft 395.

[0038] By starting the motor 394, the motor 394 will drive the rotating shaft 395 and the fan blade 396 to rotate. At the same time, when the fan blade 396 rotates, it will generate negative pressure in the negative pressure chamber 392.

[0039] The inner wall of the negative pressure chamber 392 is fixedly connected with a filter plate 397, and the filter plate 397 is connected to the negative pressure chamber 392, the collection box 38 and the feed hopper 1.

[0040] The filter plate 397 installed inside the negative pressure chamber 392 can effectively filter dust from outside the negative pressure chamber 392 into the device, thereby ensuring the cleanliness of the device and reducing the adverse effects that dust may have on the operation of the device.

[0041] A specific application of this embodiment is as follows: During use, the object to be rolled can be placed into the feed hopper 1. Due to the object's weight, it will press down the two hinged protective doors 21 on the feed hopper 1. During the pressing process, the dampers 24 and spring 25 on the back of the protective doors 21 will compress synchronously. When the protective doors 21 are no longer pressed by the weight, the two protective doors 21 will reset under the pushing action of spring 25. At the same time, the inclined plates 26 and 27 inside the feed hopper 1 cooperate to ensure that the object entering the feed hopper 1 is rolled evenly. The material flows into the roller press 31 for rolling. Furthermore, the special design of the inclined plates 26 and 27 effectively prevents some of the splashed material from flying outwards under strong pressure, thus greatly improving safety during operation. When the feed hopper 1 needs to be installed on the roller press 31, it can be temporarily placed on the roller press 31. Then, the clamping plate 35 on the L-shaped plate 32 is pulled outwards. During the pulling process, the clamping plate 35 slides outwards on the two sliding rods 3. On the outer wall of 4, and simultaneously, the second spring 36 on the outer wall of the slide bar 34 is compressed. Through this operation, the feed hopper 1 can be correctly placed on the top of the roller press 31. After placement, the two clamping plates 35 are released. At this time, the two clamping plates 35 will be pushed by the second spring 36 on them, so that the feed hopper 1 can be fixed to the roller press 31. This setting can reduce the cumbersome installation process and thus improve installation efficiency. In addition, during the process of the roller press 31 rolling the object, dust will be generated. This dust will float upward and accumulate on the feed hopper 31. Dust cannot escape from hopper 1. In this case, motor 394 can be started. After motor 394 starts, it will drive shaft 395 and fan blade 396 to rotate. At the same time, when fan blade 396 rotates, it will generate negative pressure in negative pressure chamber 392. Furthermore, through the action of filter hole 391, suction will be generated in collection box 38. In this way, dust floating in hopper 1 can be adsorbed into collection box 38 for collection. When it is necessary to clean collection box 38, simply pull collection box 38 outward to remove it for easy cleaning.
