Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of roller press feeding devices, specifically a roller press DSH double arc electric feeding device. Background Technology
[0002] Traditional roller presses use push rods to drive a gate plate in a reciprocating swing motion to regulate material flow. During adjustment, as the gate plate opens, the distance between its end and the roller surface increases. This causes material to overflow from the gap between the gate plate and the roller surface during operation, resulting in low material pressure and insufficient material throughput. Furthermore, significant material leakage causes severe vibrations in the moving and stationary rollers, leading to shutdowns due to excessive fluctuations in roller gap, pressure, and current. This frequent start-stop of the roller press affects system stability and severely impacts normal production. Therefore, we propose a DSH dual-arc electric feeding device for roller presses to address these issues. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides a DSH double-arc electric feeding device for roller presses, which solves the problems mentioned in the background art.
[0005] (II) Technical Solution
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A DSH double-arc electric feeding device for a roller press includes a housing. Four connecting members are fixed inside the housing, and an arc-shaped gate is rotatably connected between two corresponding connecting members. Two mounting plates are fixed at the bottom of the housing, and push rod assemblies are mounted on the top of each mounting plate. The pushing ends of the push rod assemblies slide through the housing and extend into its interior. Support seats are fixed inside the housing, and a linkage mechanism for adjusting the position of the arc-shaped gate is mounted on the top of each support seat. A hopper is fixed inside an opening at the bottom of the housing.
[0008] Furthermore, the linkage mechanism includes two bearing seats fixed to the top of the support base, a drive shaft rotatably connected between the two bearing seats, two connecting rods fixed to the surface of the drive shaft, the other end of the connecting rods being rotatably connected to the corresponding arc-shaped gate plate via a pin, a drive block being fixed to the surface of the drive shaft, and the top end of the drive block being rotatably connected to the push rod assembly via a pin.
[0009] Furthermore, both bearing housings have sealing covers installed on their side walls to protect the bearings inside.
[0010] Furthermore, a guide box is fixed inside the opening at the top of the box, and the guide box includes a box body and a connecting frame fixed on its top.
[0011] Furthermore, each of the four inspection ports on the top of the housing is fitted with an inspection cover, and each inspection cover has two handles fixed to its top.
[0012] Furthermore, protective guide plates are fixed to the arc-shaped outer surface of the arc-shaped gate.
[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a DSH double arc electric feeding device for a roller press, which has the following advantages:
[0015] This invention allows for the adjustment of the distance between two arc-shaped gate plates by pushing the linkage mechanism through two push rod assemblies. This enables the adjustment of the feed flow rate of the roller press. Since the ends of the two adjusting arc-shaped gate plates are in close contact with the two roller surfaces of the roller press, the two sets of arc-shaped gate plates will move in an equidistant arc along the edge of the roller body of the roller press. This keeps the distance between the bottom of the arc-shaped gate plate and the roller surface constant. Furthermore, the arc-shaped part of the hopper is located on the two roller surfaces of the roller press, forming a closed space with the two gate plates. This prevents the circulating material from overflowing and ensures material pressure. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown in the figure, an embodiment of the present invention discloses a DSH double-arc electric feeding device for a roller press, comprising a housing 1. Four inspection ports on the top of the housing 1 are each fitted with an inspection cover 9. Each inspection cover 9 has two handles 10 fixed to its top. The inspection covers 9 facilitate maintenance of the components inside the housing 1, while the handles 10 facilitate the removal and placement of the inspection covers 9. Four connecting members 2 are fixed inside the housing 1, and arc-shaped gates rotatably connect two corresponding connecting members 2. The outer curved surface of both the plate 3 and the arc-shaped gate 3 is fixed with a protective guide plate 11. During feeding, this prevents rapidly falling materials from directly impacting the surface of the arc-shaped gate 3, thus avoiding rapid wear of the metal substrate. The protective guide plate 11 can be made of wear-resistant materials such as high-chromium cast iron, wear-resistant ceramics, or hardened alloys. Two mounting plates 4 are fixed to the bottom of the housing 1. A push rod assembly 5 is mounted on the top of each mounting plate 4. The pushing end of the push rod assembly 5 slides through the housing 1 and extends into its interior. The interior of the housing 1 is fixed with... Support base 6, with a connecting rod mechanism 7 installed on its top for adjusting the position of the arc-shaped gate 3. A hopper 12 is fixed inside the opening at the bottom of the housing 1. When using this DSH double-arc electric feeding device for the roller press, the entire device can be installed at the roller press inlet. After the material is fed into the housing 1, it falls onto the two arc-shaped gates 3 and is positioned between the two rollers of the roller press. When the feed flow needs to be adjusted, the connecting rod mechanism 7 is activated by activating the self-locking push rod assembly 5 on both sides. The lever mechanism 7, since the arc-shaped gate 3 is rotatably connected to the corresponding linkage mechanism 7, and with the cooperation of the two sets of connecting parts 2 inside the housing 1, the two sets of linkage mechanisms 7 will push the two sets of arc-shaped gate 3 to move in an equidistant arc along the edge of the roller body of the roller press. The distance between the bottom of the arc-shaped gate 3 and the roller surface remains unchanged. When the distance between the two arc-shaped gate 3 gradually increases, the feed flow of the roller press can be increased. When the feed flow needs to be reduced, the distance between the two arc-shaped gate 3 can be reduced.
[0027] like Figure 2 and Figure 5As shown, in some embodiments, the linkage mechanism 7 includes two bearing seats 701 fixed to the top of the support base 6. Each of the two bearing seats 701 has a sealing cover 705 installed on its side walls to protect the internal bearings. Since the bearing seats 701 are installed inside the housing 1, the sealing cover 705 installed on the bearing seats 701 provides protection, preventing materials from affecting the bearings and thus extending the overall service life of the bearing seats 701. A drive shaft 702 is rotatably connected between the two bearing seats 701. Two connecting rods 703 are fixed on the surface of the roller 2. The other end of the connecting rod 703 is rotatably connected to the corresponding arc-shaped gate 3 through a pin. A drive block 704 is fixed on the surface of the transmission shaft 702. The top end of the drive block 704 is rotatably connected to the push rod assembly 5 through a pin. In use, the drive block 704 is pushed by the push rod assembly 5. At this time, the drive block 704 can drive the transmission shaft 702 to rotate. After the transmission shaft 702 rotates, with the cooperation of the connecting rods 703 on both sides, it can drive the arc-shaped gate 3 to move in an arc-shaped equidistant manner on the surface of the roller body of the roller press.
[0028] like Figure 1 , Figure 2 and Figure 6 As shown, in some embodiments, a guide box 8 is fixed inside the opening at the top of the box 1. The guide box 8 includes a box body 801 and a connecting frame 802 fixed on its top. The guide box 8 facilitates the delivery of materials into the box 1, while the connecting frame 802 facilitates the connection and fixation of the guide box 8 with the material conveying pipe to achieve continuous feeding.
[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
