Description

Technical Field

[0001] This utility model relates to the field of sealant production technology, specifically to a feeding device for producing solar-specific sealant. Background Technology

[0002] In the manufacturing process of solar modules, sealant is one of the key materials, mainly used for the encapsulation of solar panels, edge sealing, and bonding of junction boxes. Its performance directly affects the waterproofness, weather resistance, and long-term reliability of the modules. The production of solar-specific sealants requires mixing various raw materials (such as silane-modified polymers, fillers, crosslinking agents, catalysts, etc.) in specific proportions, and the precision and uniformity of the material addition process are crucial to the quality of the final product.

[0003] Chinese utility model patent CN216630403U discloses a feeding mechanism for sealant production. This mechanism utilizes a threaded drive and a connecting rod to control the reciprocating motion of a piston-pressing plate, making it easier to push the sealant out for feeding. However, during the reciprocating motion of the piston-pressing plate, some material remains between its bottom wall and the inner wall of the feeding box, which can solidify over time, affecting subsequent operations. Therefore, we propose a feeding device for the production of solar-grade sealant to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a feeding device for the production of solar-grade sealant, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding device for producing solar-grade sealant includes a housing. A pressing structure is installed inside the housing, and a conveying auger for easy material discharge is installed at the bottom of the housing. Scraping structures are respectively installed on both sides of the pressing structure. The scraping structures slide up and down along the inner wall of the housing, and their bottom ends are pointed. A fixed pulley is installed on the inner top wall of the housing. A pull rope connects the scraping structure and the pressing structure, passing through the fixed pulley. The scraping structure and the pressing structure move in opposite directions.

[0007] According to the above technical solution, the pressing structure includes a screw and a lifting plate. The screw is rotatably disposed between the inner walls of the housing. An adjusting seat is slidably disposed along the length of the screw. An adjusting component is disposed between the adjusting seat and the lifting plate.

[0008] According to the above technical solution, two inclined surfaces are provided at the bottom of the inner side of the box, the conveying auger is located in the middle and lower part of the two inclined surfaces, and a guide rod is fixed between the inner top wall of the box and the inclined surfaces, with a spring sleeved on the guide rod.

[0009] According to the above technical solution, the scraping structure includes a scraper, which is located between the inner wall of the box and the end wall of the lifting plate. Two connecting blocks are installed on one vertical side wall of the scraper, and the connecting blocks slide elastically on the guide rod.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] By setting a scraping structure between the pressing structure and the inner wall of the box, and through the cooperation of a fixed pulley and a pull rope, the pressing structure can drive the scraping structure to rise when it descends, and the pressing structure can drive the scraping structure to descend when it rises. However, the tip of the scraping structure is always located below the pressing structure, so that the residue on the inner wall of the box can be scraped off at any time, which effectively improves the cleaning effect of residue during the feeding process.

[0016] 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.

[0017] Please see Figure 1-3The present invention provides a technical solution: a feeding device for producing solar-grade sealant, comprising a housing 1, an inlet 11 (with a sealing plug attached, not shown in the figure) installed on one side wall of the housing 1, and an outlet pipe 12 installed on the other side wall, with a valve attached to the outlet pipe 12. The housing 1 has an internal cavity with two inclined surfaces at the bottom, and a feeding chamber is also provided below the cavity. A conveying auger 3 is installed in the feeding chamber and is at the same horizontal level as the outlet pipe 12. A rotary motor is connected to one end of the conveying auger 3 and is installed on the outer surface of the housing 1.

[0018] It should be further explained that the material is added into the box 1 through the feed port 11. After being added, the sealing plug is inserted (at this time, the end face of the sealing plug facing the inside of the box 1 is in the same plane as the inner wall of the box 1). The material is continuously pushed downward by the pressing structure. At the same time, the conveying auger 3 is started, so that the material is sent out from the discharge pipe 12 under the action of the conveying auger 3.

[0019] The pressing structure is set between the inner walls of the housing 1, and includes a screw 2, an adjusting seat 21, a lifting plate 4, and a connecting seat 41;

[0020] The screw 2 is a bidirectional screw 2, which is rotatably disposed between the inner walls of the housing 1 and is arranged in the horizontal direction. A rotary motor 2 is connected to one end of the screw 2, and the rotary motor 2 is installed on the outer surface of the housing 1. Limiting shafts 14 are fixedly installed on both sides of the screw 2. The ends of the limiting shafts 14 are fixedly connected to the inner walls of the housing 1. Two relatively movable adjusting seats 21 are slidably disposed between the two limiting shafts 14. The screw 2 passes through the middle of the adjusting seat 21 and is threadedly driven to it.

[0021] Grooves are provided on both ends of the lifting plate 4, and connecting seats 41 are fixedly installed on both sides of the top surface of the lifting plate 4. The connecting seats 41 and the adjusting seat 21 on the same side are connected by a shaft between their end walls and are provided with a linkage handle. There are two linkage handles.

[0022] It should be further explained that by starting the rotary motor 2, it drives the screw 2 to rotate. As the screw 2 is driven, the two adjusting seats 21 on it move relative to each other in the horizontal direction, and the lifting plate 4 is controlled to move up and down by the linkage handle connected to the lifting plate 4. When the two adjusting seats 21 move to the closest position, the linkage handle is in the vertical direction, and the lifting plate 4 is at the lowest position, but the tip of the scraper 5 is still below the lifting plate 4.

[0023] The scraping structure is set between the inner wall of the box 1 and the inner wall of the groove of the lifting plate 4. It includes a scraper 5 and a connecting block 51. The bottom end of the scraper 5 is set with a pointed structure, and two connecting blocks 51 are fixedly connected to one vertical side wall of the scraper 5.

[0024] A vertically arranged guide rod 13 is fixed between the inner top wall and the inclined surface of the box 1. The guide rod 13 passes through the connecting block 51 and slides with it. A spring is sleeved on the guide rod 13. The top end of the spring is connected to the inner top wall of the box 1, and the bottom end of the spring is connected to the top surface of the connecting block 51. The guide rod 13 also passes through the lifting plate 4 and slides with it.

[0025] A protrusion is fixedly installed on the top surface of the lifting plate 4, and an installation frame is fixedly installed on the inner top wall of the box 1. A fixed pulley 6 is provided between the side walls of the installation frame through a shaft connection. A pull rope 61 passes through the fixed pulley 6. One end of the pull rope 61 is connected to the protrusion, and the other end is connected to the top surface of the scraper 5.

[0026] It should be further explained that as the lifting plate 4 moves up and down, in conjunction with the fixed pulley 6 and the pull rope 61, the up and down movement of the scraper 5 is controlled synchronously. When the lifting plate 4 moves downward, the pull rope 61 drives the scraper 5 to move upward. Conversely, when the lifting plate 4 moves upward, the pull rope 61 drives the scraper 5 to move downward under the action of the spring. This cycle of alternating movement with the lifting plate 4 ensures that the residues adhering to the bottom wall of the lifting plate 4 and the inner wall of the box 1 are continuously scraped off during the downward pressing process and sent out with the material.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
