Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for the production of PVC transparent panels. Background Technology

[0002] The main raw material of PVC transparent sheets is plastic particles. In the production process of PVC transparent sheets, the raw materials need to be placed in the hopper first, and then the raw materials in the hopper are lifted at a constant speed to the feeding port of the extruder by the screw feeder for subsequent automated processing.

[0003] Currently, raw materials are generally placed in the hopper manually. The manual labor involves continuously adding raw materials to the hopper, which means manually moving bagged raw materials to the hopper, cutting open the bags with a knife, and letting the raw materials fall into the hopper. This is labor-intensive, especially in large-scale production, where the manual replenishment rhythm is difficult to match with the high-speed consumption demand of the equipment, which can easily lead to production interruptions or equipment idling, seriously affecting production efficiency.

[0004] Therefore, there is an urgent need to develop a feeding device that can reduce labor, has a high degree of automation, and is easy to use, in order to break through the key bottleneck in the PVC transparent sheet production process. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a feeding device for the production of PVC transparent panels that can reduce labor, has a high degree of automation, and is easy to use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A feeding device for PVC transparent sheet production includes a hopper support, on which a hopper is fixedly mounted. The upper end of the hopper is open, and the lower end of the hopper is connected to the feed inlet of a screw conveyor.

[0008] A slide is provided on one side of the hopper support, and raw material lifting components are installed on both sides of the slide. The two raw material lifting components are used to drive the raw material fixing components to move in the vertical direction. The raw material fixing components include two symmetrically arranged fixing arms, and several insert rods are provided on the two fixing arms facing each other. The raw material fixing components also include a moving structure for driving the two fixing arms to move closer or further apart from each other.

[0009] In this setup, the raw materials are packaged in bags, meaning the plastic particles are placed inside packaging bags to form bagged raw materials. These bagged raw materials are stacked vertically on a forklift pallet. The forklift transports the pallet and bagged raw materials to one side of the hopper support. The carriage slides to the outside of the bagged raw materials, and the raw material lifting component moves the raw material fixing component downwards. The moving structure causes the two fixing arms to move closer together, allowing the inserts on the fixing arms to insert into the bagged raw materials. Then, the raw material lifting component moves the raw material fixing component upwards. Because the inserts are inside the bagged raw materials, the bagged raw materials rise. The carriage then moves to the outside of the hopper support, and the raw material lifting component moves the raw material fixing component downwards. Finally, the packaging bag is manually cut open, and the plastic particles fall out. The packaging bag is then manually removed, completing the loading process. This process is repeated to achieve the feeding action. The carriage design allows for the lifting and movement of raw materials without manual handling, greatly reducing labor intensity. It is simple to operate and, compared to entirely manual feeding, offers a higher degree of automation, making it more suitable for large-scale production in factories.

[0010] Preferably, the raw material lifting assembly includes a vertically arranged lead screw, which is connected to a slide frame via a bearing. The upper end of the lead screw passes through the slide frame and is fixedly connected to the output shaft of a lifting motor. The lifting motor is fixedly mounted on the slide frame. A nut block is threaded onto the lead screw. The raw material lifting assembly also includes two vertically arranged guide rods, which are arranged on both sides of the lead screw. The two ends of the guide rods are fixedly connected to the slide frame, and the axis of the guide rods is parallel to the axis of the lead screw. Guide blocks are slidably fitted onto the guide rods. The nut block and the guide block are both fixedly connected to the lifting frame. An installation plate is fixedly mounted on the lifting frame, and the movable structure is connected to the installation plate.

[0011] Preferably, the moving structure includes a bidirectional screw with opposite threads from the center to both ends. The bidirectional screw is connected to two mounting plates via bearings. One end of the bidirectional screw passes through the mounting plate and is fixedly connected to the output shaft of a moving motor, which is fixedly mounted on the mounting plate. Two sliding rods are also fixedly mounted between the two mounting plates, located on both sides of the bidirectional screw with their axes parallel to the bidirectional screw's axis. A connecting block and a slider are fixedly mounted on the fixed arm. The slider has sliding holes that slide with the sliding rods. Nuts are threaded to both ends of the bidirectional screw, and the two nuts are fixedly mounted on the two connecting blocks.

[0012] Preferably, the end of the insertion rod is a pointed tip.

[0013] Preferably, two rollers are rotatably mounted on both sides of the lower end of the slide, and the rollers are provided with grooves in their circumference. Slide rails are provided on both sides of the hopper support, and the slide rails are fixedly installed on the ground. The rollers and slide rails are in rolling cooperation.

[0014] In summary, this PVC transparent sheet production feeding device has the advantages of reducing labor, high degree of automation, and ease of use. Attached Figure Description

[0019] like Figure 1-3 As shown, a feeding device for PVC transparent sheet production includes a hopper support 1, on which a hopper 2 is fixedly installed. The upper end of the hopper is open, and the lower end of the hopper is connected to the feed inlet of a screw conveyor 3. A slide 4 is provided on one side of the hopper support, and raw material lifting components are installed on both sides of the slide. The two raw material lifting components are used to drive a raw material fixing component to move in the vertical direction. The raw material fixing component includes two symmetrically arranged fixing arms 5, and several insert rods 6 are protruding from the two fixing arms. The raw material fixing component also includes a moving structure for driving the two fixing arms to move closer or further apart.

[0020] In this setup, the raw materials are packaged in bags, meaning the plastic particles are placed inside packaging bags to form bagged raw materials. These bagged raw materials are stacked vertically on a forklift pallet. The forklift transports the pallet and bagged raw materials to one side of the hopper support. The carriage slides to the outside of the bagged raw materials, and the raw material lifting component moves the raw material fixing component downwards. The moving structure causes the two fixing arms to move closer together, allowing the inserts on the fixing arms to insert into the bagged raw materials. Then, the raw material lifting component moves the raw material fixing component upwards. Because the inserts are inside the bagged raw materials, the bagged raw materials rise. The carriage then moves to the outside of the hopper support, and the raw material lifting component moves the raw material fixing component downwards. Finally, the packaging bag is manually cut open, and the plastic particles fall out. The packaging bag is then manually removed, completing the loading process. This process is repeated to achieve the feeding action. The carriage design allows for the lifting and movement of raw materials without manual handling, greatly reducing labor intensity. It is simple to operate and, compared to entirely manual feeding, offers a higher degree of automation, making it more suitable for large-scale production in factories.

[0021] In implementation, the raw material lifting assembly includes a vertically arranged lead screw 7, which is connected to a slide frame via bearings. The upper end of the lead screw passes through the slide frame and is fixedly connected to the output shaft of a lifting motor 8. The lifting motor is fixedly mounted on the slide frame. A nut block 9 is threaded onto the lead screw. The raw material lifting assembly also includes two vertically arranged guide rods 10, which are located on both sides of the lead screw. The two ends of the guide rods are fixedly connected to the slide frame, and the axis of the guide rods is parallel to the axis of the lead screw. A guide block 11 is slidably fitted onto the guide rod. Both the nut block and the guide block are fixedly connected to a lifting frame 12. A mounting plate 13 is fixedly mounted on the lifting frame, and a movable structure is connected to the mounting plate. There are two raw material lifting assemblies located on both sides of the slide frame. The two raw material lifting assemblies operate synchronously. The lifting motor drives the lead screw to rotate, and under the guidance of the guide rods and guide blocks, the nut blocks drive the lifting frame to move vertically, thereby raising or lowering the raw material fixing assembly.

[0022] In implementation, the moving structure includes a bidirectional screw 14, with the screw threads in opposite directions from the center to both ends. The bidirectional screw is connected to two mounting plates via bearings. One end of the bidirectional screw passes through the mounting plate and is fixedly connected to the output shaft of a moving motor 15, which is fixedly mounted on the mounting plate. Two sliding rods 16 are also fixedly mounted between the two mounting plates, located on both sides of the bidirectional screw with their axes parallel to the bidirectional screw's axis. A connecting block 17 and a slider 18 are fixedly mounted on the fixed arm. The slider has sliding holes that slide with the sliding rods. Nuts are threaded to both ends of the bidirectional screw, and the two nuts are fixedly mounted on the two connecting blocks. When fixing the bagged raw materials, the two fixed arms move closer to each other; after feeding, the two fixed arms move further apart. Therefore, the movement of the two fixed arms is synchronous and opposite. It is equipped with a bidirectional screw, which is a commonly used mechanical structure. The screw threads along the middle to both ends have opposite directions of rotation, and nuts are fitted at both ends. When the bidirectional screw rotates, the two nuts can move closer or further apart. Through the cooperation of the slide bar and the slider, the two fixed arms can only move in the horizontal direction and cannot rotate. The structure is simple and easy to use.

[0023] In practice, the end of the insertion rod is a pointed tip, facilitating quick insertion into the packaging bag.

[0024] In implementation, two rollers 19 are rotatably mounted on both sides of the lower end of the slide, and the rollers are provided with grooves around their circumference. Slide rails 20 are provided on both sides of the hopper support, and the slide rails are fixedly installed on the ground. The rollers roll in cooperation with the slide rails. The slide rails provide guidance and support for the movement of the rollers, thereby guiding the movement of the slide and ensuring that it moves accurately above the hopper, avoiding collisions with the hopper support.

[0025] Specifically, this application also includes a PLC controller to control the forward and reverse rotation of the lifting motor and the moving motor, which is a well-known attempt by those skilled in the art and does not require specific description.

[0026] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
