Description

Technical Field

[0001] This utility model relates to the field of filling technology, specifically to an auxiliary bag-threading mechanism for filling TPU granules. Background Technology

[0002] TPU (thermoplastic polyurethane) granules are a thermoplastic polymer material that combines the elasticity of rubber with the processability of plastics. They have excellent wear resistance, flexibility, weather resistance, and environmentally friendly and recyclable properties, and are widely used in injection molding, extrusion processing, 3D printing, footwear manufacturing and other fields. TPU granule filling is a key link between production and downstream applications. It involves using filling equipment to efficiently transfer TPU granules from storage silos to packaging containers such as bags, so as to facilitate the storage, transportation and sale of TPU granules.

[0003] Currently, TPU granule filling operations typically involve manually opening the packaging bag and continuously holding the bag opening tightly to align it with the filling machine's outlet. This process is not only time-consuming and inefficient, but also leads to hand muscle fatigue and high labor intensity due to the repetitive bag-opening and alignment actions. Furthermore, the instability of manual operation can cause misalignment of the bag opening, resulting in TPU granule spillage and waste. Therefore, we propose an auxiliary bag-threading mechanism for TPU granule filling. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary bag-threading mechanism for TPU granule filling. This mechanism can automatically complete the bag-threading operation of TPU granule packaging bags, effectively improving bag-threading efficiency, reducing labor intensity, and ensuring stable bag opening. It can accurately align the bag opening with the filling machine's outlet, reducing TPU granule spillage and waste. This invention solves the current problem that in TPU granule filling operations, the packaging bags are usually manually opened and the bag opening needs to be continuously held tightly by hand and aligned with the filling machine's outlet. This not only takes a long time to prepare for filling a single bag and results in low work efficiency, but also causes hand muscle fatigue and high labor intensity due to the repetitive bag opening and alignment actions. In addition, the instability of manual operation can easily cause bag opening misalignment, leading to TPU granule spillage and waste.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary bag-feeding mechanism for TPU granule filling, comprising an L-shaped bag box, a fixed plate fixedly installed on one side of the upper surface of the L-shaped bag box, a conveying channel provided inside the L-shaped bag box below the fixed plate, a through opening provided on the upper surface of the fixed plate, and symmetrically arranged movable grooves on both sides of the through opening on the upper surface of the fixed plate, the two movable grooves being V-shaped, a cylinder fixedly installed on the upper surface of the fixed plate near the rear surface, a movable plate fixedly connected to the output end of the cylinder, two connecting rods rotatably connected to the front surface of the movable plate, and clamping plates rotatably connected to the ends of the two connecting rods, movable sliders fixedly installed on the lower surfaces of the two clamping plates, the two movable sliders being located inside the two movable grooves respectively, and adsorption plates fixedly installed on the inner sides of the two clamping plates.

[0006] Preferably, auxiliary sliding grooves are symmetrically provided on both sides of the upper surface of the fixed plate, and auxiliary sliders are symmetrically fixedly installed on both sides of the lower surface of the movable plate, with the two auxiliary sliders located inside the two auxiliary sliding grooves respectively.

[0007] Preferably, an active roller and a driven roller are rotatably mounted inside the L-shaped bag box near the upper and lower surfaces, respectively. The active roller and the driven roller are connected by a conveyor belt, which is located near the conveying channel. A motor is fixedly mounted on the front surface of the L-shaped bag box near the active roller, and the end of the motor output shaft is fixedly connected to the end of the active roller. An electric cylinder is fixedly mounted on the outer back surface of the L-shaped bag box on the side away from the conveyor belt. A movable pressure plate is fixedly connected to the output end of the electric cylinder, and the movable pressure plate is located inside the L-shaped bag box.

[0008] Preferably, the L-shaped bag box has several support rollers rotatably mounted at equal intervals from top to bottom inside, and the support rollers are located between the driving roller and the driven roller.

[0009] Preferably, the front surface of the L-shaped bag box is provided with a box opening, the front of the L-shaped bag box is provided with a box door, and fixing strips are fixedly installed on the front surface of the L-shaped bag box at positions above and below the box opening.

[0010] Preferably, an observation port is provided on the front surface of the box door, and a transparent plate is fixedly installed inside the observation port.

[0011] Preferably, an L-shaped hook plate is fixedly installed on the outer surface of the box door near the electric cylinder, and a limit block is rotatably installed on the outer surface of the L-shaped bag box near the electric cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up an L-shaped bag box, a fixed plate, a movable chute, a movable slider, a through-hole, a cylinder, a clamping plate, a connecting rod, an adsorption plate, and a conveying channel, achieves the automatic completion of the bag-making operation of TPU granule packaging bags, effectively improving bag-making efficiency, reducing labor intensity, and ensuring stable bag opening. It can accurately align with the filling machine's discharge port, reducing TPU granule spillage and waste. The TPU granule packaging bags in the L-shaped bag box are conveyed upwards through the conveying channel. After the bag opening passes through the through-hole, the cylinder drives the connecting rod to move the clamping plate towards the L-shaped bag box. With the guidance of two V-shaped movable chute and movable slider, the two sets of clamping plates move towards each other and clamp the two sides of the bag opening with the adsorption plate. When the cylinder drives the clamping plate away from the L-shaped bag box in the opposite direction, the clamping plate simultaneously separates in the opposite direction, and the adsorption plate evenly opens the bag opening.

[0014] 2. This utility model achieves the effect of automatically feeding bags by setting up an electric cylinder, a moving pressure plate, a driving roller, a driven roller, a motor, and a conveyor belt. The electric cylinder drives the moving pressure plate to push the TPU granule packaging bags in the L-shaped bag box to the side of the conveyor belt and arrange them neatly. The motor drives the driving roller to drive the conveyor belt to rotate. With the help of the friction between the conveyor belt and the packaging bags, the packaging bags are automatically conveyed upward along the conveyor channel, and the bag mouth passes through the through-hole of the fixed plate.

[0015] 3. By setting an observation port and a transparent plate, this utility model allows for timely observation of the TPU granule packaging bag inventory inside the L-shaped bag box through the transparent plate inside the observation port, so as to facilitate timely replenishment.

Detailed Implementation

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figures 1-5 As shown, this utility model proposes an auxiliary bag-feeding mechanism for TPU granule filling, including an L-shaped bag box 1. A fixing plate 2 is fixedly installed on one side of the upper surface of the L-shaped bag box 1. A conveying channel 18 is provided inside the L-shaped bag box 1 below the fixing plate 2, extending to the upper and front surfaces of the L-shaped bag box 1. A through-hole 10 is provided on the upper surface of the fixing plate 2. The TPU granule packaging bags inside the L-shaped bag box 1 are conveyed upward through the conveying channel 18 and pass through the through-hole 10. The upper surface of the fixing plate 2 is symmetrically provided with moving grooves 9 on both sides of the through-hole 10, and the two moving grooves 9 are in a V-shape. A cylinder 3 is fixedly installed on the upper surface of the fixing plate 2 near the rear surface. The output end of the cylinder 3 is fixed. A movable plate 11 is connected, and two connecting rods 12 are rotatably connected to the front surface of the movable plate 11. The ends of the two connecting rods 12 are rotatably connected to clamping plates 13. Movable sliders 15 are fixedly installed on the lower surfaces of the two clamping plates 13, and the two movable sliders 15 are respectively located inside the two movable slide grooves 9. Adsorption plates 14 are fixedly installed on the inner sides of the two clamping plates 13. Auxiliary slide grooves 8 are symmetrically provided on both sides of the upper surface of the fixed plate 2. The two auxiliary slide grooves 8 are straight and parallel to each other. Auxiliary sliders 16 are symmetrically fixedly installed on both sides of the lower surface of the movable plate 11, and the two auxiliary sliders 16 are respectively located inside the two auxiliary slide grooves 8. The cooperation between the auxiliary slide grooves 8 and the auxiliary sliders 16 can limit the linear movement trajectory of the movable plate 11.

[0025] In use, the TPU granule packaging bag inside the L-shaped bag box 1 is conveyed upward through the conveying channel 18. After the bag opening passes through the through-hole 10, the cylinder 3 drives the connecting rod 12 to move the clamping plate 13 towards the L-shaped bag box 1. With the guidance of two V-shaped moving slide grooves 9 and the moving slider 15, the two sets of clamping plates 13 move towards each other and clamp the two sides of the bag opening through the adsorption plate 14 and adsorb. When the cylinder 3 drives the clamping plate 13 away from the L-shaped bag box 1 in the opposite direction, the clamping plate 13 separates in the opposite direction. The adsorption plate 14 then evenly opens the bag opening, which can automatically complete the bag-making operation of the TPU granule packaging bag, effectively improving the bag-making efficiency, reducing labor intensity, and ensuring a stable bag opening width, which can accurately align with the filling machine outlet and reduce TPU granule spillage and waste.

[0026] Example 2

The active roller 25 and the driven roller 28 are connected by a conveyor belt 26, which is located near the conveyor channel 18. A motor 17 is fixedly mounted on the front surface of the L-shaped bag box 1 near the active roller 25, and the end of the output shaft of the motor 17 is fixedly connected to the end of the active roller 25. Inside the L-shaped bag box 1, several support rollers 27 are equidistantly mounted from top to bottom. The support rollers 27 are located between the driving roller 25 and the driven roller 28. The support rollers 27 support the conveyor belt 26, so that the TPU granule packaging bags inside the L-shaped bag box 1 can better contact the conveyor belt 26 to increase the conveying friction. An electric cylinder 19 is fixedly installed on the outer surface of the L-shaped bag box 1 on the side away from the conveyor belt 26. The output end of the electric cylinder 19 is fixedly connected to a movable pressure plate 22, and the movable pressure plate 22 is located inside the L-shaped bag box 1.

[0028] The L-shaped bag box 1 has an opening 21 on its front surface, through which TPU granule packaging bags are added to the L-shaped bag box 1. A door 5 is located at the front of the L-shaped bag box 1. Fixing strips 23 are fixedly installed above and below the opening 21 on the front surface of the L-shaped bag box 1. Each of the two fixing strips 23 has a groove 24 on its opposite side, extending to the side of the fixing strip 23 closest to the electric cylinder 19. The top and bottom of the door 5 are located inside the two grooves 24, allowing the door 5 to be opened or closed by sliding. When the door 5 is closed, an L-shaped hook plate 4 is fixedly installed on the outer surface of the box door 5 near the electric cylinder 19. A limit block 20 is rotatably installed on the outer surface of the L-shaped bag box 1 near the electric cylinder 19. When the box door 5 is closed, the limit block 20 is rotated so that one end of it enters the L-shaped hook plate 4, thus fixing the box door 5. An observation port 6 is provided on the front surface of the box door 5. A transparent plate 7 is fixedly installed inside the observation port 6. The amount of TPU granule packaging bags inside the L-shaped bag box 1 can be observed in time through the transparent plate 7 inside the observation port 6 so as to replenish them in time.

[0029] In this embodiment, the electric cylinder 19 drives the moving pressure plate 22 to push the TPU granule packaging bags in the L-shaped bag box 1 to the side of the conveyor belt 26 and arrange them neatly. The motor 17 drives the active roller 25 to drive the conveyor belt 26 to rotate. With the help of the friction between the conveyor belt 26 and the packaging bags, the packaging bags are automatically conveyed upward along the conveyor channel 18. The bag mouth passes through the through hole 10 of the fixing plate 2, and the bag feeding can be completed automatically.

[0030] The above specific embodiments are merely several preferred embodiments of this utility model.
