Description

Technical Field

[0001] This utility model relates to the field of powder forming machine technology, specifically to a pressure roller structure for a forming machine. Background Technology

[0002] A powder forming machine, also known as a powder tablet press, is a small, basket-type, continuous, automatic tablet press. It is one of the essential pieces of equipment in the pharmaceutical, chemical, food, and electronics industries for processing granular raw materials into tablets or granules.

[0003] Existing powder forming machines are characterized by being small, tabletop, electric, continuous tablet compressors, which can also be hand-operated. They produce tablets with uniform thickness and high gloss, requiring no polishing. Because a single-punch tablet compressor uses only one set of dies, it is called a single-punch tablet compressor. The filling depth and tablet thickness are adjustable. Output is increased by adding a pressure roller structure centered around a shaft. However, in practice, the pressure roller and shaft are often integrated, meaning that if one pressure roller fails, the entire machine needs to be replaced, resulting in high maintenance costs. Therefore, we propose a new pressure roller structure for the forming machine. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a pressure roller structure for a molding machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is a pressure roller structure of a forming machine, including a main shaft body. Multiple abutment grooves are equally spaced at the top end of the main shaft body. A mounting groove is connected through the bottom end of each abutment groove. Multiple fixing screw holes are opened on both sides of the inner wall of the mounting groove. A mounting plate is inserted into the inside of the mounting groove. The surface of the mounting plate is opened with holes that fit with the fixing screw holes. The mounting plate is fixedly connected to one side wall of the detachable pressure roller.

[0006] Each of the abutting grooves has an abutting plug inserted inside, and the horizontal cross-sectional structure of the abutting plug matches the mounting plate. Each of the abutting plugs is fixedly connected to the bottom end of the limiting cover at equal intervals. The limiting cover has a first threaded hole in its center, and a threaded fastener is threaded into the first threaded hole.

[0007] By adopting the above technical solution, during installation, the mounting plate on the side wall of the detachable pressure roller is first aligned with the abutment groove and inserted, so that the holes on the surface of the mounting plate are aligned with the fixing screw holes opened on the inner wall of the mounting groove. At the same time, the extension plug is inserted into the extension slot to limit the mounting plate. Then, the fastener is passed through the mounting plate and the fixing screw holes to complete the fastening connection. When disassembly, maintenance and replacement are required, the above steps are reversed to remove the damaged detachable pressure roller from the outer wall of the main shaft. This allows for quick removal and replacement of a single pressure roller, which improves maintenance efficiency and reduces maintenance costs.

[0008] After the detachable pressure roller is installed and secured, the abutment plug at the bottom of the limit cover is inserted into the abutment groove, so that the abutment plug contacts the top of the mounting plate. Then, the screw fastener is screwed through the first screw hole and into the second screw hole to lock the limit cover to the top of the main shaft. This allows the abutment plug to work with the extension plug to provide auxiliary limiting for the mounting plate, improving the connection stability between the mounting groove and the mounting plate.

[0009] Specifically, the bottom end of the mounting groove is provided with an extension slot, and the abutment groove, the mounting groove and the extension slot are connected and are located on the top outer wall of the main shaft.

[0010] By adopting the above technical solution, the detachable pressure roller is installed on the side wall of the main shaft through the interconnected abutment groove, mounting groove and extension groove, which facilitates easy disassembly.

[0011] Specifically, an extension plug is fixedly connected to the bottom end of the mounting plate, and the shape of the extension plug matches the extension slot.

[0012] By adopting the above technical solution, the insertion structure of the extension plug and the extension slot is used to limit the position of the mounting plate after it is inserted into the mounting slot.

[0013] Specifically, the top end of the main shaft is provided with a second threaded hole that matches the threaded fastener.

[0014] By adopting the above technical solution, the limit cover is installed on the top of the spindle body through the second threaded hole matching the first threaded hole and the threaded fastener.

[0015] Specifically, the shape of the mounting plate matches the mounting groove, and the mounting plate is inserted into the inside of the abutment groove through an abutment plug, thereby locking onto the side wall of the spindle body.

[0016] By adopting the above technical solution, the abutment plug is inserted into the abutment groove and contacts the mounting plate, thereby cooperating with the extension plug and the extension slot to assist the mounting plate in being installed in the mounting groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] During installation, the technical solution of this application first aligns the mounting plate on the side wall of the detachable pressure roller with the abutment groove and inserts it, so that the holes on the surface of the mounting plate are aligned with the fixing screw holes opened on the inner wall of the mounting groove. At the same time, the extension plug is inserted into the inside of the extension slot to limit the mounting plate. Then, the fastener is passed through the mounting plate and the fixing screw holes to complete the fastening connection. When disassembly, maintenance and replacement are required, the above steps are reversed to remove the damaged detachable pressure roller from the outer wall of the main shaft. This allows for quick removal and replacement of a single pressure roller, which improves maintenance efficiency and reduces maintenance costs.

[0019] In this application, after the detachable pressure roller is installed and secured, the abutment plug at the bottom of the limiting cover is inserted into the abutment groove, so that the abutment plug contacts the top of the mounting plate. Then, the screw fastener is screwed through the first screw hole into the second screw hole to lock the limiting cover to the top of the main shaft. This allows the abutment plug to work with the extension plug to provide auxiliary limiting for the mounting plate, improving the connection stability between the mounting groove and the mounting plate.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figure 1-3This utility model provides a technical solution: a pressure roller structure for a molding machine, including a main shaft 1, a plurality of abutment grooves 2 are equidistantly provided at the top end of the main shaft 1, and an installation groove 3 is connected through the bottom end of each abutment groove 2. A plurality of fixing screw holes 4 are provided on both sides of the inner wall of the installation groove 3. An installation plate 6 is inserted into the inside of the installation groove 3, and the surface of the installation plate 6 is provided with holes that fit with the fixing screw holes 4. The installation plate 6 is fixedly connected to one side wall of a detachable pressure roller 8.

[0027] Each abutting groove 2 has an abutting plug 11 inserted inside, and the horizontal cross-sectional structure of the abutting plug 11 matches the mounting plate 6. Each abutting plug 11 is fixedly connected to the bottom end of the limiting cover 10 at equal intervals. The center of the limiting cover 10 has a first threaded hole 12, and the inside of the first threaded hole 12 is threaded with a threaded fastener 13.

[0028] During use and installation, firstly, align the mounting plate 6 on the side wall of the detachable pressure roller 8 with the abutment groove 2 and insert it, so that the hole on the surface of the mounting plate 6 is aligned with the fixing screw hole 4 opened in the inner wall of the mounting groove 3. At the same time, the extension plug 7 is inserted into the extension slot 5 to limit the mounting plate 6. Then, fasteners are passed through the mounting plate 6 and the fixing screw hole 4 to complete the fastening connection. When disassembly, maintenance and replacement are required, reverse the above steps to remove the damaged detachable pressure roller 8 from the outer wall of the main shaft 1. This allows for quick removal and replacement of a single pressure roller, which improves maintenance efficiency and reduces maintenance costs.

[0029] After the detachable pressure roller 8 is installed and secured, the abutment plug 11 at the bottom of the limiting cover 10 is inserted into the abutment groove 2, so that the abutment plug 11 contacts the top of the mounting plate 6. Then, the screw fastener 13 is screwed through the first screw hole 12 into the second screw hole 9 to lock the limiting cover 10 to the top of the main shaft 1. This allows the abutment plug 11 to work with the extension plug 7 to provide auxiliary limiting for the mounting plate 6, thereby improving the connection stability between the mounting groove 3 and the mounting plate 6.

[0030] As shown in the figure, the bottom end of the mounting groove 3 is provided with an extension slot 5, which is connected to the sliding groove 2, the mounting groove 3 and the extension slot 5 and is located on the top outer wall of the main shaft 1.

[0031] In use, the detachable pressure roller 8 is installed on the side wall of the main shaft body 1 through the through-connected abutment groove 2, mounting groove 3 and extension groove, which makes it easy to disassemble at any time.

[0032] As shown in the figure, an extension plug 7 is fixedly connected to the bottom of the mounting plate 6, and the shape of the extension plug 7 matches the extension slot 5.

[0033] In use, the mounting plate 6 is inserted into the mounting slot 3 and then limited in position by the insertion structure of the extension plug 7 and the extension slot 5.

[0034] As shown in the figure, the top end of the main shaft 1 has a second threaded hole 9 that matches the threaded fastener 13.

[0035] In use, the limit cover 10 is installed on the top of the spindle body 1 by using the second threaded hole 9 to engage with the first threaded hole 12 and the threaded fastener 13.

[0036] As shown in the figure, the shape of the mounting plate 6 matches the mounting groove 3, and the mounting plate 6 is inserted into the inside of the abutment groove 2 through the abutment plug 11, thereby locking onto the side wall of the spindle body 1.

[0037] In use, the abutment plug 11 is inserted into the abutment slide 2 to contact the mounting plate 6, thereby cooperating with the extension plug 7 and the extension slot 5 to assist the mounting plate 6 in being installed in the mounting slot 3.

[0038] The working principle and usage process of this utility model are as follows: First, different materials are introduced into the various feed ports of the material separator input port 14. The opening and closing of the gate is controlled to input materials into the material mixing chamber 3 in a measured manner. Then, the mixing motor 10 drives the rotating sleeve 12 on the outer periphery of the transmission rod 11 through the rotating connector 9 to rotate, thereby driving the stirring plate 13 to mix the materials from the inside. This allows subsequent materials to be quickly mixed into the previously mixed materials, thus improving the mixing efficiency. After mixing is completed, the sliding motor 6 on one side of the sliding base 5 drives the mixing plate 13 to mix the materials from the inside. The sliding connection module 8, which is screwed onto the outer periphery of the transmission screw 7, moves relative to the transmission screw 7. The bottom connector 4 passes through the sliding connection interface 2 and connects to the sliding connection module 8, thereby causing the material mixing chamber 3, which is installed at the top of the sliding connection module 8 via the bottom connector 4, to move to the other side inside the mixing tank 1. The transmission screw 7 is installed inside the mounting bracket 16. The mixing tank 1 is assisted in being installed at the center of the mounting bracket 16 by the fixing pad 15. Then, the electric feeding disc 18 installed on the side wall of the auxiliary bracket 17 is activated to tilt the material mixing chamber 3 to discharge the mixed material inside, and then it is reset.
