Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, specifically to the height adjustment and loading / unloading component of a woven bag heat setting device. Background Technology

[0002] Woven bags are a type of plastic bag widely used in the packaging industry. Their raw materials are generally various plastic materials such as polyethylene and polypropylene. Polypropylene woven bags are widely used in agriculture, industry, and logistics due to their high strength and corrosion resistance. Heat setting is a crucial step in the production and processing of woven bags. This heat setting process effectively improves the flatness, dimensional stability, and aesthetics of the woven bags.

[0003] Patent CN220332148U discloses a heat-setting device for producing polypropylene woven bags, including a base plate with lifting devices fixedly connected to both sides of the top of the base plate. The lifting devices include a lifting box, with a drive motor fixedly connected to the lower part of one end of the lifting box. The output end of the drive motor extends into the lifting box and is fixedly connected to a rotating rod. The top of the lifting rod passes through the lifting box and is fixedly connected to a movable placement device. Vertical rods are fixedly connected to both ends of the movable placement device. A support plate is fixedly connected to the upper part of one opposite end of the two vertical rods. A cylinder is fixedly connected to the top of the support plate, and the output end of the cylinder passes through the support plate and is fixedly connected to a heating plate. This invention, by setting up lifting devices, facilitates the adjustment of the height of the entire device, and the movable placement device facilitates the handling of woven bags.

[0004] The existing technology described above uses the coordinated action of a drive motor, a rotating rod, a first bevel gear, a second bevel gear, and a first threaded rod to enable the moving rod to drive two lifting rods to move stably up and down, thereby adjusting the height of the device. Through the linkage of the rotating motor, the second threaded rod, the moving groove, and the moving block, the connecting block can drive the placement frame to move left and right, facilitating the placement or removal of woven bags by workers. However, while the existing design provides certain adjustment and placement functions, its structure is overly complex. The coordinated actions between key components require precise control, increasing the manufacturing and maintenance costs of the equipment. Furthermore, the structure for placing and removing woven bags relies on the forward and reverse rotation of the second threaded rod to move the placement frame left and right. This process is not only cumbersome but also requires a long operating time, which actually prolongs the bag placement and removal cycle and reduces operational efficiency. Therefore, we propose a height adjustment and placement component for a woven bag heat-setting device. Utility Model Content

[0005] The purpose of this invention is to provide a height adjustment and loading / unloading component for a heat-setting device for woven bags, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] The height adjustment and loading / unloading components of the woven bag heat setting device include a base. The base provides support and stability for the entire device and supports other structural components. The top of the base is equipped with a height adjustment component to adjust the height of the workbench, so that the device can adapt to the height requirements of different operators and improve the convenience of operation.

[0008] The height adjustment component includes a U-shaped base plate fixedly connected to the top of the base. The U-shaped base plate provides an installation platform for the height adjustment component and serves as a support structure for the motor, threaded column, and other components. A motor is located at the top of the inner wall of the U-shaped base plate. The motor is powered by an external power source and drives the threaded column through rotational motion. The output shaft of the motor passes through the top of the inner wall of the U-shaped base plate and is coaxially connected to the threaded column. The threaded column's function is to adjust the height of the worktable by engaging with the rectangular support column through its outer wall threadedly. The outer wall of the threaded column is threadedly connected to the rectangular support column, which connects the worktable and the threaded column and slides vertically under drive, thereby changing the position of the worktable. A rectangular fixed upright is located at the top of the U-shaped base plate. The rectangular support column is slidably connected inside the rectangular fixed upright. The rectangular fixed upright provides sliding guidance for the rectangular support column and restricts its lateral sway, ensuring the stability of the rectangular support column's movement.

[0009] The top of the rectangular support column is equipped with a workbench, which serves as the main operating platform for heat setting of woven bags. It is used to place the placement frame and perform heat pressing operations. The top of the workbench has a U-shaped placement groove for fixing the placement frame and providing a stable placement position for the woven bags. The placement frame is placed in the U-shaped placement groove to accommodate the woven bags and keep them fixed during the heat setting process. The rear side of the placement frame has a discharge port for quickly unloading the woven bags after heat setting, eliminating the need for workers to directly contact the woven bags, simplifying the operation process and improving efficiency.

[0010] The workbench is equipped with a U-shaped support at the top, and a cylinder is located in the middle of the top of the U-shaped support. The cylinder's movable rod drives the movable plate to move up and down. The movable rod of the cylinder passes through the top of the U-shaped support and is fixedly connected to the movable plate. The cylinder works together to move up and down and drive the electric heating plate to heat-press and shape the woven bag. The bottom of the movable plate is equipped with an electric heating plate, which heats and shapes the woven bag in the frame to ensure the flatness and dimensional stability of the woven bag.

[0011] Preferably, the base has a circular fixed upright tube at the top and near the four corners, and the workbench has a circular vertical rod at the bottom and near the four corners. The four circular vertical rods are slidably connected to the four circular fixed upright tubes, and the circular fixed upright tubes provide sliding guidance for the circular vertical rods, thereby enhancing the vertical movement stability of the workbench.

[0012] Preferably, the front ends of both the left and right sides of the inner wall of the U-shaped placement groove are provided with sliding guide openings to guide the placement frame into the U-shaped placement groove, which facilitates the quick installation and positioning of the placement frame.

[0013] Preferably, the rear side of the placement frame is fitted with the rear side of the inner wall of the U-shaped placement groove, and the left and right sides of the placement frame are fitted with the left and right sides of the inner wall of the U-shaped placement groove, respectively, to ensure the positioning of the placement frame in the groove. Handles are provided on the left and right sides of the placement frame and at the middle of the top edge, so that the staff can manually pick up or place the placement frame.

[0014] Preferably, two electromagnets are embedded in the bottom of the inner wall of the U-shaped placement groove, which are arranged symmetrically from left to right. Iron plates are embedded in the bottom of the placement frame and near the middle of the left and right edges. When the electromagnets are energized, the two iron plates are attracted and connected to the two electromagnets respectively. The electromagnets generate magnetic force by being energized, which cooperates with the iron plates to fix the position of the placement frame, ensuring that the placement frame will not shift during operation.

[0015] Preferably, the top of the movable plate is provided with two positioning rods arranged symmetrically from left to right, and the top of the positioning rods penetrates through the top of the inner wall of the U-shaped bracket to the outside, ensuring stable up and down movement of the movable plate.

[0016] Preferably, the placement frame is located directly below the electric heating plate. When the cylinder's movable rod is fully extended, the electric heating plate is located inside the placement frame, ensuring that the electric heating plate can heat and shape the woven bag inside the placement frame.

The U-shaped base plate 20 provides an installation platform for the height adjustment component 2 and serves as a support structure for the motor 21, threaded column 22, and other components. The motor 21 is located at the top of the inner wall of the U-shaped base plate 20. The motor 21 is powered by an external power source and drives the threaded column 22 through rotational motion. The output shaft of the motor 21 passes through the top of the inner wall of the U-shaped base plate 20 and is coaxially connected to the threaded column 22. The threaded column 22 connects to the rectangular support column 24 through its outer wall. The rectangular support column 24 moves up and down, thereby adjusting the height of the worktable 3. The outer wall of the threaded column 22 is threaded with the rectangular support column 24, which connects the worktable 3 and the threaded column 22 and slides vertically under the drive, thereby changing the position of the worktable 3. The top of the U-shaped base plate 20 is provided with a rectangular fixed tube 23. The rectangular support column 24 is slidably connected in the rectangular fixed tube 23. The rectangular fixed tube 23 provides sliding guidance for the rectangular support column 24 and restricts its lateral sway, ensuring the stable movement of the rectangular support column 24.

[0033] The top of the rectangular support column 24 is equipped with a workbench 3, which serves as the main operating platform for heat setting of woven bags. It is used to place the placement frame 8 and perform heat pressing operations. The top of the workbench 3 is provided with a U-shaped placement groove 31 to fix the placement frame 8 and provide a stable placement position for the woven bags. The placement frame 8 is placed in the U-shaped placement groove 31 to accommodate the woven bags and keep them fixed during the heat setting process. The rear side of the placement frame 8 is provided with a discharge port 81 for quickly pouring out the woven bags after heat setting. This eliminates the need for workers to directly contact the woven bags, simplifying the operation process and improving efficiency.

The bottom of the movable plate 6 is equipped with an electric heating plate 7, which is connected to an external power source. The electric heating plate 7 heats and shapes the woven bag in the placement frame 8 to ensure the flatness and dimensional stability of the woven bag.

[0035] In this embodiment, a circular fixed upright tube 10 is provided at the top of the base 1 and near the four corners, and a circular vertical rod 30 is provided at the bottom of the workbench 3 and near the four corners. The four circular vertical rods 30 are slidably connected to the four circular fixed upright tubes 10 respectively. The circular fixed upright tubes 10 provide sliding guidance for the circular vertical rods 30, thereby enhancing the vertical movement stability of the workbench 3.

[0036] Specifically, the front ends of the left and right sides of the inner wall of the U-shaped placement groove 31 are provided with sliding guide ports 32 to guide the placement frame 8 into the U-shaped placement groove 31, which facilitates the quick installation and positioning of the placement frame 8.

[0037] Furthermore, the rear side of the placement frame 8 is fitted with the rear side of the inner wall of the U-shaped placement groove 31, and the left and right sides of the placement frame 8 are fitted with the left and right sides of the inner wall of the U-shaped placement groove 31 respectively, ensuring the positioning of the placement frame 8 in the groove. Handles 80 are provided on the left and right sides of the placement frame 8 and at the middle of the top edge, so that the staff can manually pick up or place the placement frame 8.

[0038] Furthermore, two electromagnets 9 are embedded in the bottom of the inner wall of the U-shaped placement groove 31, which are arranged symmetrically on the left and right. The electromagnets 9 are powered by an external power source. The controller for controlling the operation of the electromagnets 9, motor 21, electric heating plate 7 and cylinder 5 is located at the top of the base 1. Iron plates 82 are embedded in the bottom of the placement frame 8 and near the middle of the left and right edges. When the electromagnets 9 are energized, the two iron plates 82 are attracted and connected to the two electromagnets 9 respectively. The electromagnets 9 generate magnetic force through energization, which cooperates with the iron plates 82 to fix the position of the placement frame 8, ensuring that the placement frame 8 will not shift during operation.

[0039] Furthermore, the top of the movable plate 6 is provided with two positioning rods 60 arranged symmetrically from left to right.

The left and right inner walls are aligned. The electromagnet 9 is energized, and the iron plate 82 of the placement frame 8 is fixed in the U-shaped placement groove 31 by magnetic force to prevent the placement frame 8 from shaking during operation. The cylinder 5 is activated to drive the movable plate 6 to move downward, which in turn moves the electric heating plate 7 into the placement frame 8 to press the woven bag. The electric heating plate 7 is activated to heat-press and shape the woven bag. After heat shaping is completed, the movable plate 6 is controlled by the cylinder 5 to raise the electric heating plate 7 to the initial position. The power supply to the electromagnet 9 is disconnected, and the magnetic connection between the iron plate 82 at the bottom of the placement frame 8 and the electromagnet 9 is released. By holding the handle 80 of the placement frame 8, the placement frame 8 is slid out of the U-shaped placement groove 31, and the heat-shaped woven bag is poured out of the placement frame 8 through the discharge port 81, completing the heat shaping operation of a single woven bag.
