Technical Field

[0001] The present invention relates to the technical field of denim packaging, and in particular to an automated denim packaging device. Background Art

[0002] Denim baling equipment is a series of equipment used to compress, roll and package denim for storage and transportation. When baling denim, you need to consider the size and weight of the denim after baling. If you want to pack it into larger or heavier packages, you need to choose baling equipment with greater compression and a stronger frame structure. For example, some denim for export requires packaging into larger square packages that may weigh hundreds of kilograms. At this time, a large fully automatic baler is needed to meet the requirements. Choose according to the company's production scale and efficiency requirements. For companies with large output, such as factories that have to process thousands of yards of denim every day, it is necessary to complete a large number of baling tasks more efficiently in a short period of time. Different baling equipment has different adaptability to different types of strapping tape. Some equipment is specifically used for plastic strapping tape, while others are suitable for steel strapping tape. In the prior art, there are various ways to pack denim, such as cutting the denim into squares and packing them into square bags, or rolling the denim into denim roll bags. After rolling the denim roll bags, they need to be covered with plastic film for protection and then put into cylindrical plastic bags for final packaging. In the prior art, this process is usually manually operated, requiring two workers to pick up the plastic film and roll it on the denim roll bag, and then put the denim roll bag covered with plastic film into the cylindrical plastic bag.

The adsorption plate is slidably arranged relative to the negative pressure member. The negative pressure member also has a negative pressure cavity, which is used to connect the negative pressure and has a negative pressure port. When the adsorption plate passes through the negative pressure port, the inlet is connected to the negative pressure port, so that the adsorption port has adsorption force.

[0006] As a further technical solution, the negative pressure ports are arranged in a ring shape, and the distance between two adjacent negative pressure ports is smaller than the diameter of the inlet, so that after the inlet moves with the circulating conveyor belt, at least one negative pressure port can be connected to the inlet.

[0007] As a further technical solution, the adsorption chamber further comprises a strip-shaped channel portion, the strip-shaped channel portion leads to the adsorption port, and further comprises: An unlocking slider, the unlocking slider is slidably arranged on the adsorption plate, and the sliding direction is perpendicular to the surface of the circulating conveyor belt. The unlocking slider has a pressed portion, the pressed portion protrudes from the surface of the circulating conveyor belt and is used to be pressed down by the denim roll. The unlocking slider also has a sliding stopper, and after the unlocking slider slides, the sliding stopper penetrates and blocks the strip-shaped channel portion; A first elastic member, one end of which acts on the unlocking slider, and the other end of which acts on the adsorption plate, to provide the sliding stopper with a force to cancel the blocking of the strip-shaped channel portion.

[0008] As a further technical solution, there are two adsorption plates, which are respectively used to adsorb the two ends of the plastic film, and the two adsorption plates form a group, with a total of two groups, which are used to alternately provide plastic film for the denim roll and adsorb the plastic film in the film box.

[0009] As a further technical solution, the film containing box has a film containing cavity, the film containing cavity is used to contain the stacked plastic films, the film containing cavity has a delivery outlet, and the delivery outlet faces the film containing cavity; and further includes: An annular rib is arranged at the delivery outlet and is used to block the four sides of the plastic film.

[0019] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0020] Reference Figure 1 to Figure 6The present embodiment proposes a denim packaging device for wrapping a denim roll with a plastic film, comprising: a conveying platform 1 having an inclined conveying surface 101, the inclined conveying surface 101 having a through square opening 102, and the inclined conveying surface 101 is used for the denim roll to roll through; a circulating conveyor belt 2 is arranged at the through square opening 102; a film containing box 3 is arranged below the circulating conveyor belt 2, for accommodating stacked plastic films; an adsorption plate 4 is arranged on the circulating conveyor belt 2, for adsorbing the plastic film in the film containing box 3, and realizing that the denim roll that rolls through is wrapped with the plastic film.

[0021] In the denim packaging equipment, the conveyor platform 1 has an inclined conveying surface 101, which is designed to use the inclination angle to allow the denim roll to roll naturally under its own gravity. The through square opening 102 provides space for the installation and operation of the circulating conveyor belt 2. The circulating conveyor belt 2 is arranged at the through square opening 102, and it continues to operate to drive the adsorption plate 4 to move. The film storage box 3 is located below the circulating conveyor belt 2 and is used to store the stacked plastic film. The adsorption plate 4 is arranged on the circulating conveyor belt 2 and can adsorb the plastic film in the film storage box 3.

[0022] In actual work, for example, a denim roll to be packaged is placed at a high position on the inclined conveying surface 101, and the denim roll begins to roll under the action of gravity. When rolling to the position of penetrating the square opening 102, the adsorption plate 4 on the circulating conveyor belt 2 has already adsorbed the plastic film from the film container 3. As the denim roll continues to roll, it rolls the plastic film around itself, completing the wrapping of the plastic film. The advantage of this design is that it realizes the automated operation of wrapping the denim roll with plastic film, improves work efficiency, and reduces manual labor intensity.

[0023] In terms of technical effects, through the coordinated work of the mechanical structure, the plastic film wrapping process of the denim roll is completed accurately and efficiently, ensuring the quality and consistency of the wrapping. Overall working principle: The inclined structure of the conveyor table 1 is used to make the denim roll roll naturally, and through the cooperation of the circulating conveyor belt 2 and the adsorption plate 4, the plastic film in the film box 3 is automatically adsorbed and provided to the denim roll for wrapping. Overall technical effect: It provides an efficient and automated solution for the denim packaging process, improves production efficiency and packaging quality, and reduces production costs.

[0024] Furthermore, the adsorption plate 4 has an adsorption cavity 401 , and the adsorption cavity 401 has an adsorption port 402 , and the adsorption port 402 faces a direction away from the circulating conveyor belt 2 and is used to face the film containing box 3 .

[0025] In the denim packaging device, the adsorption plate 4 has an adsorption chamber 401, and the adsorption chamber 401 is provided with an adsorption port 402, which faces away from the circulating conveyor belt 2 and toward the film holding box 3. The design principle is to generate negative pressure through the adsorption chamber 401 and adsorb the plastic film from the adsorption port 402.

[0026] In actual work, for example, when the adsorption plate 4 moves to the top of the film containing box 3 along with the circulating conveyor belt 2, negative pressure is generated in the adsorption chamber 401, and air enters the adsorption chamber 401 from the adsorption port 402, so that the adsorption port 402 can firmly adsorb the plastic film in the film containing box 3.

[0027] This design has the following advantages: First, it ensures the stability and reliability of adsorption, so that the plastic film can be accurately grasped by the adsorption plate 4. Second, through the adsorption port 402 with a specific orientation, the adsorption operation can be more effectively aligned with the plastic film. For example, in continuous packaging work, the combination of the adsorption chamber 401 and the adsorption port 402 can always maintain a stable adsorption effect, which is not affected by the equipment running speed and external interference.

[0028] In terms of technical effects, the success rate and accuracy of plastic film adsorption are improved, and production interruptions and material waste caused by adsorption errors are reduced. Overall working principle: During the operation of the equipment, the adsorption cavity 401 of the adsorption plate 4 generates negative pressure through the adsorption port 402 to adsorb the plastic film, providing a reliable film source for the wrapping of denim rolls. Overall technical effect: Through this innovative design, the performance of denim packaging equipment is further optimized, and the packaging efficiency and quality are improved.

[0029] Furthermore, the adsorption chamber 401 also has an inlet 403, and also includes a negative pressure part 5, which is arranged in the circulating conveyor belt 2 and has an annular guide surface 500. The adsorption plate 4 is slidably arranged relative to the negative pressure part 5, and the negative pressure part 5 also has a negative pressure chamber 501, and the negative pressure chamber 501 is used to connect the negative pressure and has a negative pressure port 502. When the adsorption plate 4 passes through the negative pressure port 502, the inlet 403 is connected with the negative pressure port 502, so that the adsorption port 402 has adsorption force.

[0030] In the denim packaging device: the adsorption chamber 401 has an inlet 403, and the negative pressure member 5 is arranged in the circulating conveyor belt 2 and has an annular guide surface 500. The adsorption plate 4 is slidably arranged relative to the negative pressure member 5, and the negative pressure member 5 also has a negative pressure chamber 501, and the negative pressure chamber 501 is connected to the negative pressure and has a negative pressure port 502. The design principle is that when the adsorption plate 4 passes through the negative pressure port 502, the inlet 403 is connected to the negative pressure port 502, so that the adsorption port 402 generates adsorption force.

[0031] In actual operation, for example, the circulating conveyor belt 2 drives the adsorption plate 4 to move continuously. When the adsorption plate 4 moves to the position of the negative pressure port 502 of the negative pressure member 5, since the inlet 403 is connected with the negative pressure port 502, the negative pressure in the negative pressure chamber 501 is transmitted to the adsorption chamber 401 through the inlet 403, so that the adsorption port 402 generates a strong adsorption force, which can reliably adsorb the plastic film.

[0032] The advantages of this design are: first, timely supply of negative pressure is achieved through precise position control, ensuring that adsorption force is only available when the plastic film is needed, saving energy and improving the efficiency of the negative pressure system. Second, the annular guide surface 500 can guide the adsorption plate 4 to accurately align and connect with the negative pressure port 502, improving the stability and reliability of the system. For example, during long-term continuous operation, this precise negative pressure supply mechanism can always maintain a stable adsorption effect and is not affected by equipment vibration and changes in operating speed.

[0033] In terms of technical effects, the accuracy and stability of plastic film adsorption are significantly improved, and the situation of plastic film falling off or adsorption failure caused by unstable adsorption force is reduced. Overall working principle: During the operation of the equipment, the circulating conveyor belt 2 drives the adsorption plate 4 to move. When the adsorption plate 4 reaches the position of the negative pressure port 502 of the negative pressure part 5, the negative pressure is transmitted to the adsorption chamber 401 so that the adsorption port 402 generates adsorption force to adsorb the plastic film, thereby achieving efficient and stable plastic film adsorption operation. Overall technical effect: Through this ingenious negative pressure control design, the performance of denim packaging equipment is further optimized, the packaging efficiency and quality are improved, and the equipment operating cost and failure rate are reduced.

[0034] Furthermore, the negative pressure ports 502 are arranged in a ring shape, and the distance between two adjacent negative pressure ports 502 is smaller than the diameter of the inlet 403 , so that after the inlet 403 moves with the circulating conveyor belt 2 , at least one negative pressure port 502 can be connected to the inlet 403 .

[0035] In the present denim packaging equipment: the negative pressure ports 502 are arranged in a ring shape, and are designed so that the distance between two adjacent negative pressure ports 502 is smaller than the diameter of the inlet 403. The purpose is to ensure that the adsorption chamber 401 can continue to be connected to the negative pressure chamber 501 during the entire process of the adsorption plate 4 following the circulating conveyor belt 2. Because no matter where the adsorption plate 4 moves to, there will always be at least one negative pressure port 502 in whole or in part, and parts of two negative pressure ports 502 can be connected to the inlet 403 of the adsorption plate 4, so that the adsorption plate 4 can continuously ensure negative pressure, that is, through multiple negative pressure ports 502 arranged in a ring shape, no matter how the position of the adsorption plate 4 on the circulating conveyor belt 2 changes, the connection between the adsorption chamber 401 and the negative pressure chamber 501 can be guaranteed.

[0036] In actual work, for example, the circulating conveyor belt 2 is constantly running, driving the adsorption plate 4 to move. Due to the annular arrangement of the negative pressure port 502, even if the adsorption plate 4 is at different positions of the conveyor belt, or even during turning or speed change, there can always be at least one negative pressure port 502 connected to the inlet 403 of the adsorption plate 4, so that the adsorption chamber 401 continues to maintain a negative pressure. This design brings significant advantages: First, it realizes the uninterrupted supply of adsorption force, ensuring that the adsorption port 402 can continuously adsorb the plastic film, thereby improving the continuity and stability of the packaging work. Second, it avoids the plastic film from falling off or adsorption failure due to interruption of the adsorption force, thereby improving the quality and efficiency of packaging. For example, in long-term continuous packaging operations, no matter how the operating state of the equipment changes, the annularly arranged negative pressure port 502 can ensure that the adsorption plate 4 always maintains an effective adsorption function, thereby greatly reducing the occurrence of failures and defective products.

[0037] In terms of technical effects, it effectively ensures the continuity and stability of plastic film adsorption, and significantly improves the working performance and reliability of the packaging equipment. Overall working principle: During the operation of the equipment, the annularly arranged negative pressure port 502 provides uninterrupted negative pressure communication for the adsorption plate 4, so that the adsorption chamber 401 continues to maintain negative pressure, thereby achieving continuous adsorption of the plastic film by the adsorption port 402, ensuring the smooth progress of the denim packaging work. Overall technical effect: Through this innovative negative pressure port arrangement design, the performance of the denim packaging equipment is greatly optimized, enabling it to complete the packaging task efficiently and stably, meeting the needs of large-scale production.

[0038] Furthermore, the adsorption chamber 401 also has a strip-shaped channel portion 404, which leads to the adsorption port 402, and further includes: The unlocking slider 6 is slidably arranged on the adsorption plate 4, and the sliding direction is perpendicular to the surface of the circulating conveyor belt 2. The unlocking slider 6 has a pressed portion 601, which protrudes from the surface of the circulating conveyor belt 2 and is used to be pressed down by the denim roll. The unlocking slider 6 also has a sliding stopper 602. After the unlocking slider 6 slides, the sliding stopper 602 penetrates and blocks the strip-shaped channel portion 404. The first elastic member 7 has one end acting on the unlocking slider 6 and the other end acting on the adsorption plate 4 , providing the sliding stopper 602 with a force to cancel the blocking strip channel portion 404 .

[0039] In the present denim packaging equipment: the adsorption chamber 401 also has a strip-shaped channel portion 404 leading to the adsorption port 402. The unlocking slider 6 is slidably disposed on the adsorption plate 4, and its sliding direction is perpendicular to the surface of the circulating conveyor belt 2. The unlocking slider 6 has a pressed portion 601 protruding from the surface of the circulating conveyor belt 2, which is used to be pressed down by the denim roll. The unlocking slider 6 also has a sliding stopper 602, and after the unlocking slider 6 slides, the sliding stopper 602 can penetrate and block the strip-shaped channel portion 404. One end of the first elastic member 7 acts on the unlocking slider 6, and the other end acts on the adsorption plate 4, providing the sliding stopper 602 with a force to cancel the blocking of the strip-shaped channel portion 404.

[0040] The design principle is: under normal conditions, the first elastic member 7 prevents the sliding stopper 602 from blocking the strip channel 404, and the suction port 402 can normally absorb the plastic film. When the denim roll presses down the pressed portion 601, the unlocking slider 6 slides, and the sliding stopper 602 blocks the strip channel 404, thereby stopping the absorption.

[0041] In actual operation, for example, when the adsorption plate 4 adsorbs the plastic film and moves with the circulating conveyor belt 2, and is ready to provide the plastic film to the denim roll, the denim roll gradually approaches and presses down the pressed portion 601. At this time, the unlocking slider 6 overcomes the elastic force of the first elastic member 7 and slides, the sliding stopper 602 blocks the strip channel portion 404, the adsorption force of the adsorption port 402 disappears, and the plastic film is smoothly wound on the denim roll.

[0042] The advantages of this design are: first, it can accurately control the release timing of the plastic film, ensuring that the plastic film is separated from the adsorption plate 4 at the right time and wound on the denim roll. Second, through the automatic response of the mechanical structure, the need for manual intervention and control is reduced, and the degree of automation of the equipment is improved. For example, in the process of continuous packaging, each denim roll can accurately trigger the unlocking slider 6 to achieve smooth transfer and winding of the plastic film.

[0043] In terms of technical effects, the accuracy and stability of plastic film winding are improved, the interference of adsorption force on the winding process is reduced, and the quality and efficiency of packaging are improved. Overall working principle: When the equipment is running, when the unlocking slider 6 is not pressed down, the adsorption port 402 is normally adsorbed; when it is pressed down by the denim roll, the sliding stopper 602 cuts off the strip channel part 404, stops adsorption, and realizes accurate transfer and winding of the plastic film. Overall technical effect: Through this ingenious design, the performance of denim packaging equipment is further optimized, and the automation level and work efficiency of packaging are improved.

[0044] Furthermore, there are two adsorption plates 4, which are respectively used to adsorb the two ends of the plastic film, and the two adsorption plates 4 form a group, with two groups in total, which are used to alternately provide plastic film for the denim roll and adsorb the plastic film in the film box 3.

[0045] In the denim packaging equipment, there are two adsorption plates 4, which are used to adsorb the two ends of the plastic film respectively. The two adsorption plates 4 form a group, and there are two groups in total. The design principle is to realize continuous and efficient supply of plastic film to the denim roll through the alternating work of the two groups of adsorption plates 4, and to adsorb the plastic film in the film box 3 in time, thereby reducing waiting time and improving work efficiency.

[0046] In actual work, for example, when the first group of suction plates 4 sucks the plastic film and rolls the plastic film onto a denim roll, the second group of suction plates 4 simultaneously sucks the plastic film in the film container 3 and prepares to do so. When the first group finishes its work, the second group immediately provides the plastic film for the next denim roll, while the first group sucks the plastic film in the film container 3 again, and the process is repeated alternately.

[0047] The advantages of this design are: first, it greatly improves the working efficiency of the equipment, reduces the waiting time when a single adsorption plate 4 is working, and realizes uninterrupted packaging operation. Second, the alternating operation of the two groups of adsorption plates 4 can balance the load of the equipment and extend the service life of the equipment. For example, in large-scale denim packaging production, the alternating operation of the two groups of adsorption plates 4 can meet the high-speed and continuous production requirements and ensure the smooth progress of the production process.

[0048] In terms of technical effects, the speed and continuity of denim packaging are significantly improved, the production cycle is reduced, and the overall performance and production efficiency of the equipment are improved. Overall working principle: During the operation of the equipment, the two groups of adsorption plates 4 alternately adsorb plastic film and provide plastic film for the denim rolls to achieve efficient and continuous packaging. Overall technical effect: Through the ingenious configuration of the two groups of adsorption plates 4, the performance of the denim packaging equipment is greatly optimized, enabling it to better adapt to the needs of large-scale production, bringing higher production efficiency and economic benefits to the enterprise.

[0049] Furthermore, the film box 3 has a film cavity 301, which is used to accommodate stacked plastic films. The film cavity 301 has a delivery outlet 302, which faces the film cavity 301; it also includes an annular rib 8, which is arranged at the delivery outlet 302 to block the plastic film on all sides.

[0050] In the denim packaging device: the film box 3 has a film cavity 301 for accommodating stacked plastic films, and the film cavity 301 is provided with a delivery port 302 facing the film cavity 301. The annular rib 8 is arranged at the delivery port 302. The design principle is to limit the position of the plastic film at the delivery port 302 by the annular rib 8, to prevent the plastic film from accidentally falling or shifting from the delivery port 302 when it is not adsorbed, and to ensure that the adsorption plate 4 can accurately adsorb the plastic film.

[0051] In actual work, for example, the plastic film stacked in the film-containing cavity 301 may have a trend of moving outwards due to its own weight and extrusion. At this moment, the annular rib 8 has effectively stopped the surrounding of the plastic film, so that it can only be active within the limited range of the delivery port 302.

[0052] The advantages of this design are: first, it ensures that the plastic film is neatly arranged and stably stored in the film container 3, which is convenient for accurate adsorption of the adsorption plate 4. Second, it reduces the adsorption failure or incomplete adsorption caused by improper position of the plastic film, and improves the reliability of equipment operation. For example, in long-term continuous operation, even if the amount of plastic film in the film container cavity 301 gradually decreases, the annular rib 8 can always maintain effective blocking and positioning of the remaining plastic film.

[0053] In terms of technical effects, the stability and accuracy of plastic film supply are significantly improved, and equipment failures and packaging quality problems caused by plastic film position deviation are reduced. Overall working principle: When the equipment is running, the plastic film in the film cavity 301 is neatly located at the delivery outlet 302 under the restriction of the annular rib 8, waiting for the adsorption of the adsorption plate 4, thereby ensuring the continuity and reliability of the plastic film supply during the denim packaging process. Overall technical effect: Through the setting of the annular rib 8, the performance of the film box 3 is further optimized, and the working efficiency and packaging quality of the denim packaging equipment are improved.

[0054] Furthermore, it also includes a sliding push plate 9, which is slidably arranged in the film holding cavity 301 and is used to push the stacked plastic film close to the delivery outlet 302; one end of the second elastic member 10 acts on the sliding push plate 9, and the other end acts on the inner wall of the film holding box 3, providing the second elastic member 10 with a force to push the sliding push plate 9 close to the plastic film.

[0055] In the denim packaging device, a sliding push plate 9 is arranged in the film holding chamber 301, and a second elastic member 10 is also provided. One end of the second elastic member 10 acts on the sliding push plate 9, and the other end acts on the inner wall of the film holding box 3, providing a force for the sliding push plate 9 to approach the plastic film.

[0056] The design principle is to use the elastic force of the second elastic member 10 to push the sliding push plate 9, so that the stacked plastic film always remains close to the delivery port 302, which is convenient for the adsorption plate 4 to adsorb. In actual work, for example, as the plastic film is continuously adsorbed out of the delivery port 302 by the adsorption plate 4, the amount of plastic film in the film holding cavity 301 gradually decreases. At this time, under the action of the second elastic member 10, the sliding push plate 9 continuously pushes the remaining plastic film to move toward the delivery port 302, ensuring that there is always plastic film available for adsorption at the delivery port 302.

[0057] This design brings the following advantages: First, it can automatically replenish the position of the plastic film, avoiding adsorption failure or reduced adsorption efficiency due to the plastic film being far away from the delivery port 302. Second, it reduces the need for manual intervention to adjust the position of the plastic film, and improves the automation and work efficiency of the equipment. For example, in a long-term continuous packaging operation, the sliding push plate 9 can continuously and stably supply plastic film to the delivery port 302 under the push of the second elastic member 10, ensuring the continuity of production.

[0058] In terms of technical effects, the stability and continuity of the plastic film supply are effectively improved, and the reliability and operating efficiency of the equipment are enhanced. Overall working principle: During the operation of the equipment, as the plastic film is consumed, the second elastic member 10 pushes the sliding push plate 9, so that the plastic film is always close to the delivery port 302, which facilitates the adsorption of the adsorption plate 4. Overall technical effect: Through this design, the performance of the film box 3 is further optimized, so that the denim packaging equipment can operate more stably and efficiently.

[0059] Furthermore, it also includes a curling piece 11. The curling pieces 11 are arranged on both sides of the conveying platform 1. The denim rolled up with the plastic film passes between the two curling pieces 11. The curling piece 11 has a curling slot 1101. The curling slot 1101 is used for the two ends of the plastic film to pass through and be rolled into strips.

[0060] In the denim packaging device, a hemming piece 11 is provided on both sides of the conveying platform 1. The hemming piece 11 has a hemming slot 1101. The design principle is that when the denim roll is rolled onto the plastic film and passes between the two hemming pieces 11, the two ends of the plastic film are rolled into strips through the hemming slots 1101, so that the plastic film can be more tightly and neatly wrapped on the denim roll.

[0061] In actual work, for example, after the denim roll is rolled on the conveyor 1 and rolled with plastic film, it continues to move forward and enters the area between the two curling pieces 11. As the denim roll moves forward, the two ends of the plastic film enter the corresponding curling grooves 1101 respectively. The special shape and size of the curling grooves 1101 allow the two ends of the plastic film to be naturally rolled into strips when passing through. The advantages of this design are: first, it improves the tightness and neatness of the plastic film wrapping, thereby enhancing the protective effect on the denim roll. Second, it makes the appearance of the wrapped denim roll more regular, which is convenient for subsequent storage and transportation. For example, in large-scale denim packaging production, the curling piece 11 can ensure the quality consistency of each package and improve the overall quality of the product.

[0062] In terms of technical effects, the quality and effect of plastic film wrapping are significantly improved, and the added value and market competitiveness of the product are increased. Overall working principle: When the equipment is running, the denim roll with plastic film passes between the two curling pieces 11, and the two ends of the plastic film are rolled into strips under the action of the curling groove 1101, achieving a better wrapping effect. Overall technical effect: Through the setting of the curling piece 11, the function of the denim packaging equipment is further improved, and the quality and aesthetics of the packaged product are improved.

[0063] Furthermore, it also includes a receiving barrel 12, which is obliquely arranged at the lower end of the conveying platform 1 and is used to receive the denim wrapped with a plastic film and guide it into a plastic tube bag.

[0064] In the denim packaging equipment, the receiving barrel 12 is tiltedly arranged at the lower end of the conveying platform 1. The design principle is to use the tilted structure of the receiving barrel 12 to receive the denim rolled down from the conveying platform 1 and wrapped with plastic film, and then steadily guide it into the plastic tube bag to complete the entire packaging process.

[0065] In actual work, for example, when the denim roll is wrapped with plastic film and reaches the lower end of the conveyor 1, it will naturally fall into the receiving barrel 12. The inclination angle and inner wall smoothness of the receiving barrel 12 enable the denim roll to slide smoothly under the action of gravity. The advantages of this design are: first, it realizes seamless connection of the packaging process and improves work efficiency. Second, it avoids collision and damage of the denim roll during the transfer process, ensuring the quality of the product. For example, in continuous packaging operations, the receiving barrel 12 can quickly and accurately guide the wrapped denim roll into the plastic tube bag, reducing the time and labor intensity of manual operation.

[0066] In terms of technical effects, the packaging process is effectively optimized, and the continuity of production and the integrity of products are improved. Overall working principle: When the equipment is running, the denim roll wrapped in plastic film enters the receiving barrel 12 from the lower end of the conveyor table 1, and under its guidance, it smoothly enters the plastic tube bag to achieve efficient and orderly packaging operations. Overall technical effect: Through the setting of the receiving barrel 12, the automation level and overall performance of the denim packaging equipment are further improved, bringing higher production benefits to the enterprise.
