Description

Technical Field

[0001] The utility model relates to the technical field of plastic woven bag production equipment, in particular to a bag transporting device of a plastic woven bag cutting, sleeve-sewin g machine. Background Art

[0002] The production process of plastic woven bags usually includes several key steps, such as cutting, sewing and packaging. To improve production efficiency, the woven bags can be transported to the processing area by conveyor belts.

[0003] In the prior art, after searching, it was found that a Chinese patent discloses "A bag transport device for a plastic woven bag cutting, sleeve and sewing machine", and its application number is "201621380332.8". The above patent mainly includes a suction box, a negative pressure device and a conveying mechanism. The suction box is connected to the negative pressure device, and the upper surface of the suction box is provided with air holes to directly absorb the woven bags. The conveying mechanism is connected to the suction box to move the position of the suction box. Although the above utility model connects the suction box to the negative pressure device, the upper surface of the suction box is provided with air holes to directly absorb the woven bags, and the conveying mechanism is connected to the suction box to move the position of the suction box, thereby achieving the purpose of conveying woven bags, it is only necessary to set an air suction port on the suction box, saving energy and reducing production costs. However, the suction box is installed on the conveyor belt to achieve the mobile operation. This connection method makes it impossible for the conveyor belt to rotate in a closed loop, resulting in the suction box needing to move back and forth at both ends of the conveyor belt to complete the conveying of the woven bags. This means that after the suction box has conveyed a batch of woven bags, it needs to return to the starting position before it can be conveyed again. This reciprocating movement increases the operation time. The high round-trip time and cost of the suction box make it impossible to achieve efficient continuous transportation, resulting in reduced production efficiency. Especially under large-scale production requirements, the reciprocating method is particularly uneconomical. Therefore, the utility model provides a bag transport device for a plastic woven bag cutting, sleeve sewing machine to solve the problems raised in the above background technology.

[0022] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0023] Reference Figure 1-4 The embodiment of the present invention is a bag transporting device of a plastic woven bag cutting, sleeve and sewing machine, which includes a frame 1, a conveyor belt 2 is provided inside the frame 1, and two first pressing assemblies are symmetrically provided above the conveyor belt 2. The first pressing assembly includes a first mounting plate 4 with a U-shaped structure, two first transmission wheels 5 symmetrically connected to the inside of the first mounting plate 4 and a first transmission belt 6 installed between the first transmission wheels 5. A gap is set between the bottom of the first transmission belt 6 and the conveyor belt 2, and a suitable distance is set to ensure that the plastic woven bag fits tightly between the first transmission belt 6 and the conveyor belt 2.

[0024] When the plastic woven belt is located between the first transmission belt 6 and the conveyor belt 2, the conveyor belt 2 provides power for the movement of the plastic woven bag, and under the pressure of the first transmission belt 6, it plays a positioning effect, and at the same time enables the plastic woven bag to better contact with the conveyor belt 2 to complete the conveying work. It has a simple structure and high conveying efficiency, can effectively improve the production efficiency of plastic woven bags, and is highly practical.

[0025] Two second pressing assemblies are symmetrically provided at the top of the frame 1 and on one side of the first mounting plate 4. The second pressing assembly includes a second mounting plate 9 that can move up and down and has a U-shaped structure, two second transmission wheels 10 that are symmetrically rotatably connected to the inside of the second mounting plate 9, a second transmission belt 11 installed between the second transmission wheels 10, a second fixing frame 7 that is fixedly connected to the top of the frame 1 and has a U-shaped structure, and two cylinders 8 installed on the top of the second fixing frame 7. The bottom ends of the piston rods of the cylinders 8 are fixedly connected to the tops of the corresponding second mounting plates 9.

[0026] When the plastic woven bag moves from the left to below the second fixing frame 7, the cylinder 8 operates to push the second mounting plate 9 downward, causing the second transmission belt 11 to contact the plastic woven bag, thereby achieving a pressure-holding effect on the plastic woven bag. By cooperating with the conveyor belt 2, the plastic woven bag is squeezed, which helps to compress the woven bag, allowing it to be transported more smoothly by the conveyor belt 2 and move between the first transmission belt 6 and the conveyor belt 2, thus preventing the plastic woven bag from getting stuck during transportation.

[0027] A first adjustment assembly is provided at the top of the frame 1 and at both ends of the first mounting plate 4. The first adjustment assembly includes a first fixing frame 3 fixedly connected to the top of the frame 1 and having a U-shaped structure, a first slide groove 15 opened on the side of the first fixing frame 3 close to the first mounting plate 4, a connecting plate 16 fixedly connected to the end of the first mounting plate 4, a second slide groove 19 opened on the top of the first fixing frame 3, a screw 17 slidably connected to the inside of the second slide groove 19 and a nut 18 threadedly connected to the outside of the screw 17, the connecting plate 16 is slidably connected to the inside of the first slide groove 15, and the bottom end of the screw 17 is fixedly connected to the top of the connecting plate 16.

[0028] The first mounting plate 4 is movably connected to the second fixing frame 7 through the cooperation between the connecting plate 16 and the first slide 15. The screw 17 and nut 18 are provided to position the first mounting plate 4. By moving the position of the first mounting plate 4, the spacing between the first transmission belts 6 can be adjusted, which facilitates the pressing and conveying of plastic woven bags of different sizes, and provides greater flexibility.

[0029] A second adjusting assembly is also provided between the top of the second fixed frame 7 and the cylinder 8. The second adjusting assembly includes a bidirectional screw rod 12 rotatably connected to the top of the second fixed frame 7, two movable plates 14 symmetrically threadedly connected to the outside of the bidirectional screw rod 12, and a motor 13 fixedly connected to one side of the second fixed frame 7. The top of the cylinder 8 is fixedly connected to the bottom of the corresponding movable plate 14, and one end of the bidirectional screw rod 12 close to the motor 13 passes through the second fixed frame 7 and is fixedly connected to the output shaft of the motor 13. The movable plate 14 is slidably connected to the second fixed frame 7.

[0030] The motor 13 drives the bidirectional screw rod 12 to rotate. The rotating bidirectional screw rod 12 can realize the movement operation of the movable plate 14 and its cylinder 8, thereby facilitating the adjustment of the position of the second transmission belt 11 and better adapting to plastic woven bags of different sizes.

[0031] The thickness of the first transmission belt 6 extends slightly outward at the edge of the first transmission wheel 5, and the thickness of the second transmission belt 11 also extends slightly outward at the edge of the second transmission wheel 10, so as to ensure that the first transmission belt 6 and the second transmission belt 11 can fit the surface of the plastic woven bag more closely when pressing the bag, thereby improving the pressing and conveying effects.

[0032] Working Principle: When the plastic woven bag moves from the left to below the second fixing frame 7, the cylinder 8 operates to push the second mounting plate 9 downward, causing the second transmission belt 11 to contact the plastic woven bag, thereby achieving a pressure-holding effect on the plastic woven bag. By cooperating with the conveyor belt 2, the plastic woven bag is squeezed, which helps to compress the woven bag, allowing it to be transported more smoothly by the conveyor belt 2 and move between the first transmission belt 6 and the conveyor belt 2, thus preventing the plastic woven bag from getting stuck during transportation.

[0033] When the plastic woven belt is located between the first transmission belt 6 and the conveyor belt 2, the conveyor belt 2 provides power for the movement of the plastic woven bag, and under the pressure of the first transmission belt 6, it plays a positioning effect, and at the same time enables the plastic woven bag to better contact with the conveyor belt 2 to complete the conveying work. It has a simple structure and high conveying efficiency, can effectively improve the production efficiency of plastic woven bags, and is highly practical.

[0034] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
