Description

Technical Field

[0001] This utility model relates to the field of pellet mill pressure roller cleaning technology, specifically a pressure roller anti-clogging self-cleaning device that is easy to disassemble. Background Technology

[0002] Pellet mill pressure rollers are core components of pelleting equipment in industries such as feed, pharmaceuticals, and chemicals. They are primarily used to extrude powdery or paste-like materials through die holes to form granular products. Pressure rollers are typically made of high-strength alloy steel, increasing friction with the material to ensure uniform extrusion. During pelleting, material residue can easily adhere to the roller surface, leading to decreased pellet quality, equipment wear, or microbial growth, necessitating regular cleaning.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] During the processing of feed, feed residue adheres to the surface of existing pellet mill rollers, making it difficult for operators to clean them without removing them. Cleaning the roller surface is often done manually, which is time-consuming and labor-intensive, and there is a lack of mechanisms that can automatically clean the rollers. Utility Model Content

[0005] The purpose of this invention is to provide a self-cleaning device for preventing clogging of pressure rollers that is easy to disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-cleaning device for preventing clogging of pressure rollers that is easy to disassemble, comprising pressure rollers, with the left and right ends of the two pressure rollers respectively rotatably connected to the inner walls of the left and right sides of a housing, and connecting frames clamped on the front and rear sides of the top of the housing, with a collection box provided at the bottom end of the connecting frame near the pressure rollers, and a connecting support plate provided above the collection box on the connecting frame, with a buffer mechanism fitted into the side of the connecting support plate near the pressure rollers, and a scraper adsorbed and connected to the end of the buffer mechanism near the pressure rollers, and a transmission mechanism sleeved on the outer wall of one end of the two pressure rollers.

[0007] In a further preferred embodiment, a plurality of electric telescopic rods are screwed onto the inner wall of the top side of the connecting frame near the top opening of the box. The driving end of the electric telescopic rod is provided with a clamping plate, and the side of the clamping plate near the box is provided with an anti-slip layer.

[0008] More preferably, the inner walls of the left and right sides of the collection box are rotatably connected to guide plates, and a number of compression springs are provided between the bottom side of the guide plate and the side wall of the collection box.

[0009] More preferably, the top of the connecting support plate is provided with a fitting groove, and a buffer mechanism is fitted inside the fitting groove.

[0010] More preferably, the buffer mechanism includes a plurality of buffer springs, each buffer spring having a fitting plate on the side near the connecting support plate, the fitting plate being fitted into the fitting groove, and a magnetic suction plate on the side of the buffer spring near the pressure roller, the magnetic suction plate being attached to a scraper on the side near the pressure roller.

[0011] More preferably, the bottom end of the scraper is provided with a magnetic absorbing plate, the magnetic absorbing plate and the magnetic absorbing plate form an adsorption connection, and the tip of the scraper is obliquely attached to the side of the pressure roller.

[0012] More preferably, the transmission mechanism includes a drive gear, which is sleeved on the outer wall of one end of one of the pressure rollers, and the driven gear is sleeved on the outer wall of one end of the other pressure roller. A drive motor is inserted into one end of the pressure roller with the drive gear sleeved on.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The connecting frame enables quick clamping and disassembly, improving installation efficiency. The collection box can collect feed residue scraped off the pressure roller surface by the scraper, preventing residue from accumulating in the box or falling into the crushing area. The rotation and opening of the guide plate allows impurities to fall automatically and return to their original position under the counter-push of the compressed spring, forming a circulating guide mechanism. The buffer mechanism can automatically adjust the contact pressure between the scraper and the pressure roller, ensuring that the scraper tip is always obliquely attached to the pressure roller surface, thereby effectively scraping off feed residue from the pressure roller surface. The magnetic connection formed by the magnetic plate and magnetic suction plate can connect or separate the scraper and the buffer mechanism without tools, facilitating quick scraper replacement.

[0020] 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a self-cleaning device for preventing blockage of pressure rollers that is easy to disassemble, including pressure rollers 1. The left and right ends of the two pressure rollers 1 are rotatably connected to the inner walls of the left and right sides of the box body 2, respectively. The top and front and rear sides of the box body 2 are clamped with connecting frames 3. The bottom end of the connecting frame 3 is provided with a collection box 4 near the pressure roller 1. The connecting frame 3 is provided with a connecting support plate 5 above the collection box 4. The connecting support plate 5 is fitted with a buffer mechanism 6 near the pressure roller 1. The end of the buffer mechanism 6 near the pressure roller 1 is connected to a scraper 7. The outer wall of one end of the two pressure rollers 1 is sleeved with a transmission mechanism 8.

[0022] In this embodiment, as Figure 1 and Figure 3 As shown, several electric telescopic rods 301 are screwed onto the inner wall of the top side of the connecting frame 3 near the top opening of the box 2. The driving end of the electric telescopic rod 301 is provided with a clamping plate 302, and the side of the clamping plate 302 near the box 2 is provided with an anti-slip layer 303.

[0023] In this embodiment, as Figure 3 As shown, guide plates 401 are rotatably connected to the inner walls of the left and right sides of the collection box 4, and several compression springs 402 are provided between the bottom side of the guide plate 401 and the side wall of the collection box 4.

[0024] In this embodiment, as Figure 1 As shown, a fitting groove 501 is provided at the top of the connecting support plate 5, and a buffer mechanism 6 is fitted inside the fitting groove 501.

[0025] In this embodiment, as Figure 3 and Figure 4As shown, the buffer mechanism 6 includes several buffer springs 601. A fitting plate 602 is provided on the side of the buffer spring 601 near the connecting support plate 5. The fitting plate 602 is fitted inside the fitting groove 501. A magnetic suction plate 603 is provided on the side of the buffer spring 601 near the pressure roller 1. A scraper 7 is adsorbed and connected on the side of the magnetic suction plate 603 near the pressure roller 1.

[0026] In this embodiment, as Figure 4 As shown, the bottom end of the scraper 7 is provided with a magnetic suction piece 701. The magnetic suction piece 701 and the magnetic suction plate 603 form an adsorption connection, and the tip of the scraper 7 is obliquely attached to the side of the pressure roller 1.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the transmission mechanism 8 includes a drive gear 801, which is sleeved on the outer wall of one end of one of the pressure rollers 1, and a driven gear 802 is sleeved on the outer wall of one end of the other pressure roller 1. A drive motor 803 is inserted into one end of the pressure roller 1 on which the drive gear 801 is sleeved.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the easy-to-disassemble pressure roller anti-clogging self-cleaning device operates as follows during use:

[0029] First, the operator can vertically clamp the connecting frame 3 onto the front and rear outer walls of the top of the box 2, and simultaneously activate the electric telescopic rod 301 on the inner wall of the connecting frame 3 via the external controller. This will cause the drive end to laterally push the connected clamping plate 302 towards the outer wall of the box 2 until the anti-slip layer 303 on the clamping plate 302 can tightly adhere to the outer wall of the box 2, thereby firmly clamping the connecting frame 3 onto the box 2 and achieving rapid installation of the self-cleaning device. Then, the operator can bring the magnetic suction plate 701 at the bottom of the scraper 7 into contact with the magnetic suction plate 603 on one side of the buffer spring 601. Using the magnetic force of the two, the scraper 7 will be attracted and fixed to the buffer spring. At part 601, the tip of the scraper 7 can be obliquely attached to the side of the pressure roller 1. At the same time, the operator can start the drive motor 803, causing its output shaft to drive the inserted pressure roller 1 to start rotating. During this process, the drive gear 801 sleeved on the outer wall of the end of this pressure roller 1 will also be driven to rotate together. Through the driven gear 802 meshing with the drive gear 801, the other pressure roller 1 will rotate synchronously in the opposite direction, so that the two pressure rollers 1 rotate in opposite directions to squeeze the feed raw materials. During this process, the scraper 7 will automatically clean the rotating pressure roller 1. At the same time, when the pressure roller 1 rotates, the buffer spring 6 of its buffer mechanism 6 will... 01 will be in a compressed state, and through elastic force, the magnetic suction plate 603 and scraper 7 will always be in contact with the surface of the pressure roller 1. The angled design of the tip of the scraper 7 can effectively scrape off the feed residue adhering to the surface of the pressure roller 1, avoiding blockage. The impurities scraped off by the scraper 7 will fall downwards into the collection box 4 area located below the scraper 7 under the action of gravity, and will remain on the guide plate 401 at the top opening of the collection box 4. When the impurities accumulate to a certain weight, the guide plate 401 will be pressed down by the impurities. During this period, several compression springs 402 located between the bottom of the guide plate 401 and the side wall of the collection box 4 will be squeezed and compressed simultaneously, thereby making the guide plate 401... 1. Slightly rotate to one side to open the top opening of the collection box 4, guiding impurities to slide down the guide plate 401 into the collection box 4. After the impurities have fallen, the compression spring 402 will reset and push the guide plate 401 back to its original position, continuing to guide subsequent impurities. After the impurity cleaning operation is completed, the operator can reverse the electric telescopic rod 301 to retract its drive end, driving the clamping plate 302 away from the box 2, releasing the clamping force on the box 2. Then the entire connecting frame 3 can be lifted upwards, and the collection box 4, connecting support plate 5, buffer mechanism 6 and scraper 7 can be removed as a whole, making it convenient to inspect the inside of the box 2 and the pressure roller 1.
