Description

Technical Field

[0001] This utility model belongs to the field of drip irrigation tape production technology, specifically relating to an automatic weighing device for finished drip irrigation tape rolls. Background Technology

[0002] With the vigorous promotion and implementation of national policies on green agriculture, agricultural industrialization, and intelligent manufacturing, drip irrigation tape manufacturers are facing pressure to reduce costs, improve efficiency, and address labor shortages. Currently, the auxiliary production processes after the drip irrigation tape is wound are basically completed by traditional manual labor and semi-automated machinery. The finished product processing includes multiple processes such as sampling, printing, weighing, label printing, label affixing, and wrapping.

[0003] Existing online automatic weighing machines (mainly consisting of a weighing platform and an integrated conveyor belt on top) are used in situations such as... Figure 1 As shown, the conveyor belt of the drip irrigation tape production line is placed end-to-end with the conveyor belt of the preceding process. After the preceding process is completed, the drip irrigation tape roll is conveyed to the conveyor belt of the online automatic weighing equipment. The weighing task is automatically completed on the conveyor belt of the online automatic weighing equipment, and the weighing data is further uploaded to the industrial control computer. Because the conveyor belt of the online automatic weighing equipment is placed end-to-end with the conveyor belt of the preceding process, there is a certain gap between the front end of the online automatic weighing equipment's conveyor belt and the rear end of the preceding process's conveyor belt. At the same time, the ends of both the conveyor belt and the conveyor belt are arc-shaped, which further increases the gap between the two. During the process of conveying the drip irrigation tape roll from one conveyor belt to the other, when the roll is relatively small, it is easy to get stuck in the gap between the conveyor belt and the conveyor belt, thus affecting the conveying and weighing of the drip irrigation tape roll and resulting in poor performance.

[0004] Therefore, this utility model makes further designs based on existing online automatic weighing equipment. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides an automatic weighing device for finished drip irrigation tape rolls. During the material transfer and weighing process, the rolls on the conveyor belt can tilt downwards and slide onto the conveyor belt above the weighing platform, making them less likely to get stuck in the gap between the rear end of the conveyor belt and the front end of the weighing platform, thus facilitating the automatic material transfer and weighing of the drip irrigation tape rolls.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic weighing device for finished drip irrigation tape rolls, comprising a weighing platform and a conveyor belt integrally mounted on the weighing platform, wherein an adjustable support is provided at the bottom of the weighing platform, the adjustable support comprising an internal threaded sleeve and an external threaded leg.

A cross brace 22 is fixedly connected between two adjacent internal threaded support sleeves 18. The external threaded support leg 19 can be screwed up and down relative to the internal threaded support sleeve 18 for adjustment. The support pad 20 is used for anti-slip support at the bottom of the external threaded support leg 19. The height scale in the scale groove 21 can be used to help check the screw-out length of the external threaded support leg 19. The smallest scale unit is 2mm, which is not specifically shown in the figure.

[0029] Reference Figure 2 , Figure 3 and Figure 4 As shown, the front end of the conveyor belt 2 is further provided with an adjustable roller frame, which includes a fixed plate 3, a turntable 7, a side baffle 9 and a roller rod 11.

[0030] Reference Figure 2 , Figure 3 and Figure 4As shown, further, the fixed plate 3 is fixed to the left and right sides of the front end of the conveyor belt 2. A fixed shaft 4 is fixedly connected to the middle position of the side of the fixed plate 3 opposite to the conveyor belt 2. A shaft end 5 is fixedly connected to the end of the fixed shaft 4 opposite to the conveyor belt 2. Several insertion holes 6 are opened on the fixed plate 3, and the insertion holes 6 are distributed in a ring at equal intervals. A turntable 7 is set on the side of the fixed plate 3 opposite to the conveyor belt 2. A turning hole 8 is opened in the middle position of the turntable 7. A side baffle 9 is integrally formed at the front end of the turntable 7. Several holes are opened on the side baffle 9. A shaft hole 10 is formed, and several rollers 11 are arranged between the left and right side baffles 9. The rollers 11 are linearly and equidistantly distributed. Roller shafts 12 are fixedly connected to the middle positions of both ends of the rollers 11, and the roller shafts 12 are rotatably connected to the shaft hole 10. A shaft hole 13 is opened inside the front end of the turntable 7, and the shaft hole 13 communicates with the insertion hole 6. A bushing 14 is fixedly connected to the front end of the turntable 7 on the side opposite to the fixed plate 3. An insertion shaft 15 is slidably connected inside the bushing 14, and the insertion shaft 15 is close to the fixed plate 3. One end of the roller 15 is inserted into the socket 6.

A spring 17 is fixedly connected to the end of the bushing 14 opposite to the turntable 7, and the end of the spring 17 opposite to the bushing 14 is fixedly connected to the pull button 16. The turntable 7 can rotate relative to the fixed plate 3 through the rotating hole 8 and the fixed shaft 4. The shaft end 5 is used to limit the outer end of the fixed shaft 4 to prevent the side baffle 9 from moving outward and falling off. The roller 11 can rotate relative to the side baffle 9 through the roller shaft 12 and the shaft hole 13. It makes rolling contact with the material roll, allowing the material roll to fall smoothly. During use, by pulling the lever 16 outward, the insert shaft 15 is disengaged from the insertion hole 6 on the fixed plate 3, which releases the limiting and fixing state of the turntable 7 and the side baffle 9, allowing the rotation adjustment of the turntable 7 and the side baffle 9. After adjustment, by releasing the lever 16, the insert shaft 15 returns to its original position under the rebound force of the spring 17 and can be locked in the corresponding insertion hole 6 on the fixed plate 3, thus limiting and fixing the adjusted turntable 7 and the side baffle 9.

[0031] In this embodiment, the present invention has an adjustable bracket at the bottom of the weighing platform 1, mainly including an internal threaded sleeve 18 and an external threaded leg 19. At the same time, an adjustable roller frame is provided at the front end of the weighing platform 1, mainly including a fixed plate 3, a shaft end 5, a side baffle 9, and a roller 11. In use, the overall height of the weighing platform 1 and the conveyor belt 2 can be lowered by adjusting the adjustable bracket. At the same time, through the rotational cooperation between the turntable 7 and the fixed plate 3, and the snap-fit ​​cooperation between the shaft 15 on the shaft end 5 and the insertion hole 6 on the fixed plate 3, the tilt height of the side baffle 9 and the roller 11 can be adjusted upward, and the front end of the side baffle 9 and the roller 11 can be pressed against the rear bottom of the conveyor belt 23 of the previous process. During the material transfer and weighing process, the material roll on the conveyor belt 23 can tilt downward and slide onto the conveyor belt 2 on the upper part of the weighing platform 1, and is not easy to get stuck in the gap between the rear end of the conveyor belt 2 and the front end of the weighing platform 1, so as to facilitate the automatic material transfer and weighing of the drip irrigation tape roll 24.

[0032] The usage process and working principle of this utility model are as follows: Before use, place the weighing platform 1 and conveyor belt 2 behind the conveyor belt 23 of the previous process. Then, screw down the external thread support leg 19 and support pad 20 relative to the internal thread support sleeve 18. The height scale in the scale groove 21 can be used to help check the screw-out length of the external thread support leg 19. Through the above operation, the overall height of the weighing platform 1 and conveyor belt 2 can be lowered. Then, pull the pull button 16, spring 17 and insert shaft 15 outward to disengage the insert shaft 15 from the insertion hole 6 on the fixed plate 3, thereby releasing the limiting and fixing state of the turntable 7 and the side baffle 9. Then, keep the insert shaft 15 in the pulled-out state and rotate it relative to the fixed shaft 4 on the fixed plate 3 through the rotating hole 8 on the turntable 7 to adjust the side baffle 9 and roller 11. The tilt height is adjusted so that the front end of the side baffle 9 and the roller 11 are close to the bottom of the rear end of the conveyor belt 23. Small gaps have little impact and do not need to be so precise. Then, the pull button 16, spring 17 and insert shaft 15 are released. Under the rebound force of spring 17, the pull button 16, spring 17 and insert shaft 15 spring back to their original positions. The insert shaft 15 can be locked into the corresponding insertion hole 6 on the fixed plate 3 to limit and fix the adjusted side baffle 9 and roller 11. In use, the drip irrigation tape roll 24 on the conveyor belt 23 of the previous process can be automatically transferred to the conveyor belt 2 on the weighing platform 1. During the transfer process on the conveyor belt 2, the weighing can be automatically completed, and the weighed drip irrigation tape roll 24 can be further transferred to the next station through the conveyor belt 2.
