Description

Technical Field

[0001] This utility model relates to the field of feeding high-viscosity materials, and in particular to a pressure cap for feeding high-viscosity materials. Background Technology

[0002] In the production and processing of chemical products such as water-soluble coatings and metal surface treatment agents, a variety of viscous materials with high viscosity, strong thixotropy or easy sedimentation are often involved. These materials generally have poor flowability, weak self-flowability, and are prone to stratification or gel structure after standing. It is difficult to achieve stable material supply by relying on gravity or pump self-priming during the feeding and conveying process.

[0003] Currently, to ensure the conveying stability of the feeding system, a pressure cap structure is usually used in the storage container (such as ton drum, IBC drum or high-level material tank) to apply external pressure to the material and force it to flow towards the discharge port. Among them, the pressure cap, also known as the pressure plate, is a typical mechanical propulsion mechanism that is widely used in semi-enclosed or closed containers. It is especially suitable for the efficient discharge of paste, high viscosity and thixotropic materials. The device presses down vertically through pneumatic, hydraulic or electric drive, which can effectively reduce the adhesion between the material and the container wall, reduce the amount of residue, and significantly improve the discharge efficiency and system stability.

[0004] The existing pressing structure for feeding high-viscosity materials requires the pressure cap to be fully raised and reset after one round of pressing and conveying before the next batch of materials can be added. During the rising process, residual materials are easily adhered to the bottom surface, causing the risk of dripping contamination or cross-contamination. In addition, in order to avoid the pressure cap blocking the feed inlet, it needs to be raised to a higher position, which not only occupies the space above, but also prolongs the time cycle of the up and down reciprocating motion, resulting in poor continuity of the entire feeding process and affecting production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pressure cap for feeding highly viscous materials. It solves the problems of existing pressure structures for feeding highly viscous materials, where the pressure cap must be fully raised and reset after one round of pressing and conveying. During the rising process, residual material easily adheres to its bottom surface, causing the risk of dripping contamination or cross-contamination. To avoid the pressure cap blocking the feed inlet, it needs to be raised to a higher position, which not only occupies the space above but also prolongs the time cycle of the up-and-down reciprocating motion, resulting in poor continuity of the entire feeding process and affecting production efficiency.

[0006] The technical solution of this utility model is as follows: a pressure cap for feeding high-viscosity materials, comprising a material cylinder, a pressure plate and a partition plate arranged inside the material cylinder, a lifting frame fixedly installed on the upper end of the pressure plate, a drive frame arranged on the right side of the lifting frame, a drive motor fixedly installed on the upper end of the drive frame, a drive screw arranged inside the drive frame, guide rods arranged on the front and rear sides of the drive screw, a rotating seat fixedly installed at the lower end of the drive frame, a gear ring fixedly installed on the outer side of the rotating seat, a fixed platform fixedly connected to the outer side of the upper end of the material cylinder, an annular slide rail fixedly installed on the upper end of the fixed platform, a drive gear arranged on the front side of the upper end of the fixed platform, and a drive motor arranged on the front side of the lower end of the fixed platform.

[0007] Preferably, a reversing valve is provided at the lower end of the material cylinder, and a partition is fixedly connected to the inner side of the material cylinder, dividing the inner cavity of the material cylinder into two working chambers, left and right. The input end of the reversing valve is connected to the working chambers on the left and right sides of the partition, respectively, for switching the flow path of the material.

[0008] Preferably, the pressure plate has a semi-circular structure design, with the arc-shaped outer edge of the pressure plate slidingly attached to the inner side of the material cylinder through a sealing strip, and the straight edge of the pressure plate slidingly attached to the surface of the partition through a sealing strip.

[0009] Preferably, the lower end of the lifting frame is fixedly connected to the pressure plate, and the upper end of the lifting frame is fixedly installed with a threaded sleeve and a sliding sleeve. The threaded sleeve is threadedly connected to the drive screw, and the sliding sleeve is slidably sleeved with the guide rod.

[0010] Preferably, the output end of the drive motor is fixedly connected to the upper end of the drive screw, the lower end of the drive screw is rotatably connected to the drive frame through a bearing, the guide rod and the drive screw are arranged in parallel, and both the upper and lower ends of the guide rod are fixedly connected to the drive frame.

[0011] Preferably, the rotating seat has a ring structure design and is movably connected to the upper end of the fixed platform through a ring slide rail to realize rotational movement around the axis of the material cylinder.

[0012] Preferably, the second drive motor is fixedly connected to the fixed platform, and the output end of the second drive motor extends to the upper end of the fixed platform and is fixedly connected to the drive gear, with the drive gear and the gear ring meshing with each other.

[0013] The beneficial effects of this utility model are:

[0014] 1. This pressure cap for feeding high-viscosity materials divides the inner cavity into two independent working chambers by setting a partition inside the material cylinder. With the help of a pressure plate that can be switched, the material can be fed into the other chamber at the same time while the material is being pressed and conveyed in one chamber. Through the alternating working mode, the intermittent interruptions caused by the traditional pressing device having to wait for the pressure plate to be fully reset before the material can be added are avoided, the feeding cycle is shortened and the continuity of material conveying is improved.

[0015] 2. The pressure cap used for feeding high-viscosity materials slides relative to the edge of the fixed partition during the rotation and switching of the pressure plate. The partition acts as a scraper to automatically scrape off any residual material that may adhere to the bottom of the pressure plate.

[0016] This device is based on an improvement of existing equipment, so the improvement cost is relatively low and it will not cause a large amount of existing equipment to be discarded. It ensures the processing effect while reducing the investment in improvement costs, making it suitable for large-scale production. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figures 1-5This utility model provides an embodiment: a pressure cap for feeding highly viscous materials, including a material cylinder 1, a pressure plate 2 and a partition plate 3 on the inner side of the material cylinder 1, a lifting frame 4 fixedly installed on the upper end of the pressure plate 2, a drive frame 5 on the right side of the lifting frame 4, a drive motor 6 fixedly installed on the upper end of the drive frame 5, a drive screw 7 on the inner side of the drive frame 5, guide rods 8 on the front and rear sides of the drive screw 7, a rotating seat 9 fixedly installed on the lower end of the drive frame 5, a gear ring 10 fixedly installed on the outer side of the rotating seat 9, a fixed platform 11 fixedly connected to the outer side of the upper end of the material cylinder 1, an annular slide rail 12 fixedly installed on the upper end of the fixed platform 11, a drive gear 13 on the front side of the upper end of the fixed platform 11, and a drive motor 14 on the front side of the lower end of the fixed platform 11.

[0025] Please see Figures 1-4 In this embodiment, a reversing valve 101 is provided at the lower end of the material cylinder 1. The partition 3 is fixedly connected to the inner side of the material cylinder 1, dividing the inner cavity of the material cylinder 1 into two working chambers, left and right. The input end of the reversing valve 101 is connected to the working chambers on the left and right sides of the partition 3 respectively, for switching the flow path of the material. The pressure plate 2 has a semi-circular structure design. The arc-shaped outer edge of the pressure plate 2 is slidably attached to the inner side of the material cylinder 1 through a sealing strip. The straight edge of the pressure plate 2 is slidably attached to the surface of the partition 3 through a sealing strip. The lower end of the lifting frame 4 is fixedly connected to the pressure plate 2. The upper end of the lifting frame 4 is fixedly installed with a threaded sleeve 401 and a sliding sleeve 402. The threaded sleeve 401 is threadedly connected to the drive screw 7. The sliding sleeve 402 is slidably sleeved with the guide rod 8. The output end of the drive motor 6 is fixedly connected to the upper end of the drive screw 7. The lower end of the guide rod 8 and the drive frame 5 are rotatably connected by bearings. The guide rod 8 and the drive screw 7 are arranged in parallel. Both the upper and lower ends of the guide rod 8 are fixedly connected to the drive frame 5. When the drive motor 6 starts, it drives the drive screw 7 to rotate, thereby driving the lifting frame 4 to slide down along the guide rod 8. The lifting frame 4 drives the pressure plate 2 to move down synchronously, so that it moves down along the inner wall of the material cylinder 1 and one side surface of the partition 3, applying pressure to the highly viscous material in the chamber, realizing the pressing and conveying. During the pressing of one side chamber by the pressure plate 2 and the subsequent reset and rise, the other side chamber of the partition 3 at the upper end of the material cylinder 1 remains open, while the reversing valve 101 on this side is closed, and material can be added synchronously, thereby realizing the alternating operation of feeding and discharging at the same time, effectively shortening the feeding interval time and improving the continuity and efficiency of material conveying.

[0026] Please see Figures 2-5In this embodiment, the rotating seat 9 has a ring structure design and is movably connected to the upper end of the fixed platform 11 through the ring slide rail 12 to realize the rotational movement around the axis of the material cylinder 1. The second drive motor 14 is fixedly connected to the fixed platform 11. The output end of the second drive motor 14 extends to the upper end of the fixed platform 11 and is fixedly connected to the drive gear 13. The drive gear 13 and the gear ring 10 mesh with each other. When the side pressure plate 2 completes the pressing and rises to reset, the second drive motor 14 starts, drives the drive gear 13 to rotate, and then drives the gear ring 10 to rotate, causing the rotating seat 9 to rotate half a turn. The rotating seat 9 drives the pressure plate 2 to rotate synchronously 180° in the upper part of the inner side of the material cylinder 1 through the drive frame 5, so that it moves to the other side of the partition 3. After adjusting the reversing valve 101, the pressure plate 2 is controlled to move down again to press and convey the material in the other side chamber. During the rotation of the pressure plate 2, the edge of the partition 3 slides over its bottom, which plays a scraping role and effectively removes the residual material at the bottom of the pressure plate 2.

[0027] During operation, the drive motor 6 starts, driving the drive screw 7 to rotate, which in turn drives the lifting frame 4 to slide and descend along the guide rod 8. The lifting frame 4 drives the pressure plate 2 to move down synchronously, causing it to descend along the inner wall of the material cylinder 1 and one side surface of the partition 3, applying pressure to the highly viscous material in the chamber, thus achieving material pressing and conveying. During the process of the pressure plate 2 pressing the material in one chamber and subsequently resetting and rising, the other chamber of the partition 3 at the upper end of the material cylinder 1 remains open, while the reversing valve 101 on that side is closed, allowing for simultaneous material addition. This achieves alternating operation of feeding and discharging simultaneously, effectively shortening the feeding interval. To improve the continuity and efficiency of material conveying, after the side pressure plate 2 completes the pressing and rises to reset, the drive motor 2 14 starts, drives the drive gear 13 to rotate, and then drives the gear ring 10 to rotate, causing the rotating seat 9 to rotate half a turn. The rotating seat 9 drives the pressure plate 2 to rotate synchronously 180° in the upper part of the inner side of the material cylinder 1 through the drive frame 5, so that it moves to the other side of the partition 3. After adjusting the reversing valve 101, the pressure plate 2 is controlled to descend again to press and convey the material in the other side chamber. During the rotation of the pressure plate 2, the edge of the partition 3 slides over its bottom, which plays a scraping role and effectively removes the residual material at the bottom of the pressure plate 2.

[0028] Compared to existing pressing structures for feeding high-viscosity materials, where the pressure plate must be fully raised and reset after one round of pressing and conveying before the next batch of material can be added, this application divides the inner cavity into two independent working chambers by setting a partition 3 inside the material cylinder 1, and with the switchable pressure plate 2, allows material to be added to the other chamber simultaneously while pressing and conveying material to one chamber. This alternating working mode avoids the intermittent interruptions caused by traditional pressing devices that require waiting for the pressure plate to be fully reset before adding material, shortens the feeding cycle, and improves the continuity of material conveying. Compared to existing pressure plates where residual material easily adheres to the bottom surface after rising, this application allows the bottom of the pressure plate 2 to slide relative to the edge of the fixed partition 3 during the rotation and switching process. The partition 3 acts as a scraper, automatically scraping off any residual material that may adhere to the bottom of the pressure plate 2.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
