Description

Technical Field

[0001] This utility model relates to the field of photovoltaic frame production technology, specifically to an extrusion device for photovoltaic frame production. Background Technology

[0002] Photovoltaic frames are an important component of solar photovoltaic modules. Their function is to encapsulate materials such as solar cells, glass, and backsheets, enhancing the module's strength and facilitating transportation, installation, and protection. During the production process, heated raw materials are injected into a mold using extrusion equipment to shape the photovoltaic frame into a specified form for subsequent use.

[0003] In extrusion equipment, a screw is driven by a motor to rotate, propelling the raw material through a feed pipe and injecting it into the mold via a nozzle. However, existing extrusion equipment suffers from low efficiency in processing longer frames using only a single set of nozzles, and the single feed pipe makes it inconvenient to simultaneously heat and maintain the temperature of the raw material. Therefore, this paper proposes an extrusion device for photovoltaic frame production to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide an extrusion device for photovoltaic frame production, so as to solve the problems mentioned in the background art. In the production process, some frames are long and are processed by only a single set of nozzles, resulting in low working efficiency. In addition, a single set of material conveying pipes is inconvenient for heating and heat preservation of raw materials at the same time.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion device for photovoltaic frame production, comprising an operating table, on which a frame mold is placed on the upper surface of the operating table, a servo motor is provided inside the operating table, and one end of the output shaft of the servo motor is connected to a bidirectional screw through a coupling, a sliding rod is provided on one side of the bidirectional screw, and multiple sets of movable blocks are inserted at both ends of the bidirectional screw and the sliding rod, a first feeding pipe is provided on the movable blocks at both ends of the operating table, and a second feeding pipe is provided on the movable block in the middle of the operating table, and multiple sets of support rods are provided at both ends of the first feeding pipe and the second feeding pipe, and ball bearings are embedded in the lower end of the support rods;

[0006] The first conveying pipe has a feed pipe at one end and a first motor at one end. One end of the output shaft of the first motor is connected to a first screw through a coupling. The other end of the first conveying pipe has a connecting pipe, and the lower end of the connecting pipe is connected to a second conveying pipe. The second conveying pipe has a second motor at one end and one end of the output shaft of the second motor is connected to a second screw through a coupling. Heating tubes are embedded in the outer shells of the first and second conveying pipes respectively.

[0007] The second feeding pipe is provided with a nozzle at one end of the mold near the edge, and the nozzle is covered with a protective cover. The protective cover has bolts screwed on the front and rear, and the other end of the bolts is screwed onto the nozzle. The protective cover is provided with a smoke detector on the inner wall, and the smoke detector is provided with multiple sets of wires. The other end of the wires is connected to a power supply and an alarm controller.

[0008] Preferably, the first and second feeding pipes, under the action of the servo motor, form a bidirectional limiting sliding structure with the frame mold through a bidirectional screw, a slide bar, a movable block, and the frame mold.

[0009] Preferably, the first screw and the second screw, under the action of the first motor and the second motor respectively, form a rotating structure in the first feed pipe and the second feed pipe through the output shaft and the coupling.

[0010] Preferably, the protective cover is formed by a spiral locking structure with the injection nozzle through multiple sets of bolts.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The first and second feeding pipes of the extrusion equipment for photovoltaic frame production are respectively connected to the frame mold through a bidirectional screw, slide bar, and movable block under the action of a servo motor, forming a bidirectional limiting sliding structure. This increases the efficiency of raw material extrusion into the mold through two sets of nozzles, thereby improving the forming rate of the photovoltaic frame. The first and second screws of the device are respectively connected to the first and second feeding pipes through an output shaft and coupling to form a rotating structure. This allows the material to be processed at different temperatures through different feeding pipes, thereby increasing the practicality of the device in the photovoltaic frame production process. The protective cover of the device is connected to the nozzle through multiple sets of bolts to form a spiral locking structure, thereby protecting the nozzle from extruding raw materials during the feeding process. At the same time, the working environment can be monitored through the internal smoke detector so that any malfunctions can be detected in time during the use of the device.

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: an extrusion device for photovoltaic frame production, including an operating table 1, a frame mold 2 placed on the upper surface of the operating table 1, a servo motor 3 inside the operating table 1, and a bidirectional screw 4 connected to one end of the output shaft of the servo motor 3 via a coupling, a sliding rod 5 corresponding to one side of the bidirectional screw 4, and multiple sets of movable blocks 6 inserted at both ends of the bidirectional screw 4 and the sliding rod 5, a first feeding pipe 7 respectively provided on the movable blocks 6 at both ends of the operating table 1, and a second feeding pipe 13 respectively provided on the movable block 6 in the middle of the operating table 1, multiple sets of support rods 8 respectively provided at both ends of the first feeding pipe 7 and the second feeding pipe 13, and ball bearings embedded in the lower end of the support rods 8. It should be noted that the movable blocks 6 are provided with corresponding spiral holes and through holes to ensure that the movable blocks 6 can be limited and slid.

[0019] Furthermore, the first conveying pipe 7 and the second conveying pipe 13, under the action of the servo motor 3, form a bidirectional limiting sliding structure with the frame mold 2 through the bidirectional screw 4, the slide bar 5, and the movable block 6. Thus, the material feeding efficiency inside the frame mold 2 can be increased through the two sets of conveying pipe assemblies, thereby increasing the forming efficiency in the photovoltaic frame production process.

[0020] One end of the first conveying pipe 7 is provided with an upper feed pipe 11, and one end of the first conveying pipe 7 is provided with a first motor 9. One end of the output shaft of the first motor 9 is connected to a first screw 10 through a coupling. The other end of the first conveying pipe 7 is provided with a connecting pipe 12, and the lower end of the connecting pipe 12 is connected to a second conveying pipe 13. One end of the second conveying pipe 13 is provided with a second motor 14, and one end of the output shaft of the second motor 14 is connected to a second screw 15 through a coupling. Heating tubes are embedded in the outer shells of the first conveying pipe 7 and the second conveying pipe 13, respectively. It should be noted that multiple sets of electrical equipment in this device are connected to power supply equipment through power lines, and the working status of the electrical equipment is monitored by sensors, controllers and other equipment to ensure that the electrical equipment in this device can perform normal control operations. The heating tubes in the two sets of conveying pipes are respectively controlled by the control system to heat and keep the material warm.

[0021] Furthermore, the first screw 10 and the second screw 15, under the action of the first motor 9 and the second motor 14 respectively, form a rotating structure in the first conveying pipe 7 and the second conveying pipe 13 through the output shaft and coupling. Thus, the material can be heated and kept warm through multiple sets of conveying pipes, thereby increasing the practicality of the device in the photovoltaic frame production process.

[0022] The second feeding pipe 13 is provided with a nozzle 16 at one end near the mold 2 on the side. The nozzle 16 is covered with a protective cover 17 on the outside. The protective cover 17 is screwed with bolts 18 at the front and rear, and the other end of the bolts 18 is screwed onto the nozzle 16. The protective cover 17 is provided with a smoke detector 19 on the inner wall. The smoke detector 19 is provided with multiple sets of wires, and the other end of the wires is connected to the power supply and the alarm controller respectively.

[0023] Furthermore, the protective cover 17 forms a spiral locking structure with the nozzle 16 through multiple sets of bolts 18, thereby protecting the nozzle 16 during operation and monitoring the working environment of the nozzle 16 through the smoke detector 19 to ensure the safety of the device.

[0024] Working Principle: When using the extrusion equipment for photovoltaic frame production, the protective cover 17 is first fitted onto the nozzle 16 and screwed on using multiple sets of bolts 18. This protects the connection point of the nozzle 16 when it is inserted into the frame mold 2. Simultaneously, the smoke detector 19 inside the protective cover 17 monitors the environment at the connection point, providing timely alarm in case of smoke generation due to a malfunction, ensuring safety during operation. During the photovoltaic frame extrusion process, material is fed into the first conveying pipe 7 through the feed pipe 11. The material is heated by the heating pipe embedded in the first conveying pipe 7, and the material is extruded and fed through the rotating first screw 10 driven by the first motor 9. The heated material then enters the second conveying pipe 13 through the connecting pipe 12. The material is heated and kept warm by the heating pipe inside the second feeding pipe 13, allowing the device to simultaneously heat and keep warm the material, thus increasing its practicality. Next, the servo motor 3 is started, and its output shaft drives the bidirectional screw 4 to rotate via a coupling. This, in turn, drives the two sets of feeding pipes to move synchronously via the slide bar 5 and movable block 6. After the nozzle 16 is inserted into the frame mold 2, the second motor 14 is started, driving the second screw 15 to rotate. The second screw 15 then extrudes the material into the nozzle 16 for feeding, and finally into the frame mold 2 for processing and shaping. Simultaneously, the material extrusion feeding rate can be increased through the nozzles 16 at both ends, thus avoiding the low extrusion efficiency caused by feeding only through a single set of nozzles 16 when the photovoltaic frame mold is long. This is the operating process of the extrusion equipment for photovoltaic frame production.

[0025] Although the present invention 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 the present invention should be included within the protection scope of the present invention.
