Description

Technical Field

[0001] The utility model belongs to the field of packaging equipment, and particularly relates to a waste recycling device for tear-off lids. Background Art

[0002] Tear-off lids are a common type of packaging consumables. Due to their advantages of easy opening and good sealing performance, they are widely used in the packaging of powdered foods and fluid foods.

[0003] During the production and processing of tear-off lids, since the number of waste sheet bodies generated in the processing process is large and the volume of a single waste sheet body is small, it is difficult to collect the waste. In the prior art, workers need to collect the waste sheet bodies by hand and centrally transport the collected waste sheet bodies into a waste basket for storage. Such a collection method not only increases the labor intensity of the workers but also causes the tear-off lid production line to stop for a long time, thus seriously affecting the processing efficiency of tear-off lids. At the same time, since sharp edges generally exist on the waste sheet bodies, workers are easily scratched during hand collection, resulting in potential safety hazards in the waste collection process.

[0007] Further, the positioning shaft includes a threaded section and a limiting section. The threaded section and the limiting section are respectively located on both sides of the second material guiding groove. A limiting piece is arranged at the end of the limiting section away from the second material guiding groove, and the outer diameter of the limiting piece is larger than the notch width of the guiding notch.

[0008] Further, the material guiding assembly further includes a locking sleeve sleeved on the threaded section. An internal thread matching the threaded section is provided on the inner side wall of the locking sleeve, and the locking sleeve and the second material guiding groove are respectively located on both sides of the bracket.

[0009] Further, a material guiding slope is provided inside the first material guiding groove.

[0010] Further, the first conveyor belt is inclined and arranged inside the bracket, and the feeding end of the first conveyor belt is higher than the discharging end of the first conveyor belt. The second conveyor belt is inclined and arranged inside the bracket, and the feeding end of the second conveyor belt is lower than the discharging end of the second conveyor belt.

[0011] Further, the easy-open lid waste recycling device further includes a filter screen plate detachably arranged inside the bracket, and the filter screen plate is located between the discharging end of the first conveyor belt and the feeding end of the second conveyor belt.

[0012] Further, the easy-open lid waste recycling device further includes a debris collection box arranged below the first conveyor belt. A feeding port and a discharging port are provided on the side wall of the debris collection box. The feeding port and the discharging port are respectively located on both sides of the debris collection box. A detachable discharging baffle is provided inside the discharging port, and the feeding port is detachably connected to the filter screen plate.

[0013] Further, a first driving assembly is provided on the first conveyor belt. The first driving assembly includes a first speed increaser and a first frequency conversion motor. The output shaft of the first frequency conversion motor is connected to the input shaft of the first speed increaser, and the output shaft of the first speed increaser is connected to the driving roller of the first conveyor belt.

[0014] A second driving assembly is provided on the second conveyor belt. The second driving assembly includes a second speed increaser and a second frequency conversion motor. The output shaft of the second frequency conversion motor is connected to the input shaft of the second speed increaser, and the output shaft of the second speed increaser is connected to the driving roller of the second conveyor belt.

[0015] Compared with the prior art, the easy-open lid waste recycling device of the present utility model has the following advantages:

[0016] (1) An easy-to-tear lid waste recycling device according to the present utility model can, through the cooperation of a first conveyor belt and a second conveyor belt, convey the waste generated by an easy-to-tear lid production line above a material guiding assembly, and the material guiding assembly guides the waste into a waste basket, thereby improving the recycling efficiency of the easy-to-tear lid waste and reducing the labor intensity of workers. Secondly, the material guiding assembly in this device can be adjusted in terms of the inclination angle. During the process of guiding the waste into the waste basket through the material guiding assembly, the change in the inclination angle of the material guiding assembly can adjust the accumulation point of the waste inside the waste basket, thereby avoiding the situation where the local waste accumulates too high inside the waste basket, effectively utilizing the space inside the waste basket, and reducing the dumping frequency of the waste basket. In addition, the material guiding assembly in this device includes a first material guiding groove and a second material guiding groove, and one end of the second material guiding groove is slidably arranged inside the splicing slot at the end of the first material guiding groove. When the inclination angle of the material guiding assembly changes, the sliding of the second material guiding groove inside the splicing slot can change the length of the material guiding assembly, so that the material guiding assembly can more accurately guide the waste to the corresponding accumulation point area, ensuring an ideal waste accumulation effect inside the waste basket.

[0017] (2) An easy-to-tear lid waste recycling device according to the present utility model is provided with a filter screen plate and a debris collection box between the discharge end of the first conveyor belt and the feed end of the second conveyor belt. When the waste falls from the first conveyor belt onto the second conveyor belt, the debris attached to the waste will be separated from the waste sheet body. At this time, the filter screen plate can intercept the waste sheet body, so that the second conveyor belt can send the waste sheet body into the material guiding assembly, and the debris will pass through the filter screen plate and enter the debris collection box, thereby preventing the debris entrained in the waste from splashing out after the waste leaves the material guiding assembly.

[0028] The present utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] A waste recycling device for an easy - tear lid, its structure can be composed of Figures 1-4For illustration, in this embodiment, the easy-open lid waste recycling device includes: a bracket 1, a first conveyor belt 2, a second conveyor belt 3, a material guiding component, and a waste basket 5. Among them, the first conveyor belt 2, the second conveyor belt 3, and the material guiding component are all arranged inside the bracket 1. The feeding end of the second conveyor belt 3 is located below the discharging end of the first conveyor belt 2. The material guiding component is arranged below the discharging end of the second conveyor belt 3 with an adjustable inclination angle, and the waste is arranged below the material guiding component. When in use, the staff can set this device in the waste generation area of the easy-open lid production line to facilitate the waste to enter the interior of this device. The waste entering this device will fall above the feeding end of the first conveyor belt 2 and, along with the movement of the first conveyor belt 2 and the second conveyor belt 3, successively pass through the discharging end of the first conveyor belt 2, the feeding end of the second conveyor belt 3, the discharging end of the third conveyor belt 3, and the material guiding component, and finally enter the waste basket 5 for centralized storage. Since the inclination angle of the material guiding component can be adjusted according to the usage requirements, the staff can regularly change the inclination angle of the material guiding component so that the waste forms different parabolic trajectories after leaving the material guiding component, thereby forming different waste accumulation points inside the waste basket 5, further making full use of the internal space of the waste basket 5, reducing the dumping frequency of the waste basket 5, and reducing the labor intensity of the staff.

[0030] Specifically, to achieve the ability to adjust the inclination angle of the material guiding component, as Figure 2 , Figure 3 and Figure 4 shown, the material guiding component includes a first material guiding groove 41 and a second material guiding groove 42. One end of the first material guiding groove 41 is provided with a connecting shaft 411, and the other end is provided with a splicing slot 412. One end of the second material guiding groove 42 is slidably arranged inside the splicing slot 412, and the other end is provided with a positioning shaft. Moreover, a guiding notch 11 with a length direction parallel to the length direction of the waste basket 5 is also provided on the bracket 1. During assembly, the connecting shaft 411 can be rotatably inserted into a preset shaft hole on the bracket 1, so that the first material guiding groove 41 is rotatably connected to the bracket 1, and the positioning shaft is slidably arranged inside the guiding notch 11. When it is necessary to adjust the inclination angle of the material guiding component, the staff can drive the positioning shaft to slide inside the guiding notch 11, so that the material guiding component rotates around the connecting shaft 411, thereby adjusting the inclination angle formed between the material guiding component and the horizontal plane, and further ensuring that the waste can be accurately thrown into a preset waste accumulation point in the waste basket 5 after passing through the material guiding component.

[0031] In addition, since one end of the second material guiding groove 42 is slidably arranged inside the splicing slot 412, when the inclination angle of the material guiding component is adjusted by sliding the positioning shaft inside the guiding notch 11, a relative sliding will also occur between the second material guiding groove 42 and the first material guiding groove 41, so that the material guiding component has different lengths at different inclination angles. Figure 2This is a cross-sectional view of the device. As shown in the figure, when the inclination angle formed between the material guiding component and the horizontal plane is relatively large, the material guiding component will throw the waste towards the waste accumulation point near the second conveyor belt 3 in the waste basket 5. At this time, the second material guiding groove 42 will slide into the splicing slot 412, thereby shortening the length of the material guiding component and facilitating the rapid separation of the waste from the material guiding component. Correspondingly, when the inclination angle formed between the material guiding component and the horizontal plane is relatively small, the material guiding component will throw the waste towards the waste accumulation point far from the second conveyor belt 3 in the waste basket 5. At this time, the second material guiding groove 42 will slide out of the splicing slot 412, thereby increasing the length of the material guiding component and extending the movement stroke of the waste on the material guiding component to ensure that the waste is accurately thrown into the waste accumulation point.

[0032] Optionally, to improve the smoothness of the waste movement inside the material guiding component, a material guiding slope 413 can be provided inside the first material guiding groove 41. By setting the material guiding slope 413, the waste entering the material guiding component can be guided so that the waste inside the first material guiding groove 41 quickly slides into the second material guiding groove 42.

[0033] As Figure 4 shown, the positioning shaft in this embodiment can include a threaded section 421 and a limiting section 422. The threaded section 421 and the limiting section 422 are respectively located on both sides of the second material guiding groove 42, and a limiting piece 423 with an outer diameter larger than the width of the guiding notch 11 is provided at one end of the limiting section 422 away from the second material guiding groove 42. When assembling the positioning shaft and the bracket 1, the threaded section 421 and the limiting section 422 should be respectively inserted into the guiding notches 11 on both sides of the second material guiding groove 42 to improve the stability of the second material guiding groove 42.

[0034] In addition, to facilitate locking the position of the positioning shaft, the material guiding component can further include a locking sleeve 6. Specifically, the locking sleeve 6 should be sleeved on the threaded section 421. An internal thread matching the threaded section 421 is provided on the inner side wall of the locking sleeve 6, and the locking sleeve 6 and the second material guiding groove 42 are respectively located on both sides of the bracket 1. When it is necessary to drive the positioning shaft to slide inside the guiding notch 11, the staff can loosen the locking sleeve 6 so that the positioning shaft can freely slide inside the guiding notch 11, facilitating the adjustment of the inclination angle of the material guiding component. When the inclination angle of the material guiding component meets the actual requirements, the staff can tighten the locking sleeve 6 so that the end of the locking sleeve 6 abuts against the side wall of the bracket 1, thereby locking and limiting the guiding component by means of frictional resistance.

[0035] In the actual working process, since the processing of the easy-to-tear lid requires the use of a cutting device to punch and cut the raw sheet material, small debris is easily formed at the edge of the waste material due to punching and cutting. To prevent small debris from splashing outwards during the process of the waste material being thrown into the waste basket 5, the easy-to-tear lid waste recycling device described in this embodiment may further include a filter screen plate 7. Specifically, the filter screen plate 7 is detachably arranged inside the bracket 1 by bolts, and the filter screen plate 7 is located between the discharge end of the first conveyor belt 2 and the feed end of the second conveyor belt 3.

[0036] Since the feed end of the second conveyor belt 3 is located below the discharge end of the first conveyor belt 2, after the waste material is separated from the first conveyor belt 2, the waste material will fall towards the second conveyor belt 3. When the falling waste material comes into contact with the second conveyor belt 3, the collision between the waste material and the second conveyor belt 3 will cause the debris to separate from the waste sheet body. At this time, the filter screen plate 7 will intercept the waste sheet body so that the waste sheet body moves along with the second conveyor belt 3 towards the guiding component, while the debris will pass through the filter screen plate 7 to prevent the debris from entering the interior of the guiding component.

[0037] Optionally, to facilitate the collection of the debris passing through the filter screen plate 7, the device may further include a debris collection box 8. As Figure 2 shown, the debris collection box 8 is arranged below the first conveyor belt 2. There are a feed port 81 and a discharge port on the side wall of the debris collection box 8. The feed port 81 and the discharge port are respectively located on both sides of the debris collection box 8. A detachable discharge baffle 82 is arranged inside the discharge port, and the feed port 81 and the filter screen plate 7 are detachably connected by bolts. Since the feed port 81 and the filter screen plate 7 are detachably connected, when the debris passes through the filter screen plate 7, it will enter the interior of the debris collection box 8. The staff can regularly open the discharge baffle 82 to collect the debris accumulated inside the debris collection box 8, thus preventing the debris from polluting the external environment.

[0038] In addition, to enhance the separation effect between the debris and the waste material, the first conveyor belt 2 and the second conveyor belt 3 in this embodiment can both be arranged in an inclined posture inside the bracket 1. As Figure 2 shown, the feed end of the first conveyor belt 2 should be higher than the discharge end of the first conveyor belt 2, and the feed end of the second conveyor belt 3 should be lower than the discharge end of the second conveyor belt 3. Since the feed end of the first conveyor belt 2 is higher and the discharge end is lower, the first conveyor belt 2 can quickly send the waste material above the second conveyor belt 3. After the waste material falls onto the second conveyor belt 3, since the feed end of the second conveyor belt 3 is lower than the discharge end of the second conveyor belt 3, the waste material and the debris will stay briefly at the feed end of the second conveyor belt 3, thus providing sufficient time for the separation of the debris and the waste material and preventing the debris from entering the interior of the guiding component.

[0039] As an alternative embodiment of this embodiment, for the convenience of controlling the conveying speed of the waste material inside the device, the device is provided with a first driving assembly on the first conveyor belt 2 and a second driving assembly on the second conveyor belt 3. Specifically, the first driving assembly may include a first speed increaser / reducer 21 and a first variable-frequency motor 22, and the second driving assembly may include a second speed increaser / reducer 31 and a second variable-frequency motor 32. During assembly, the output shaft of the first variable-frequency motor 22 should be connected to the input shaft of the first speed increaser / reducer 21, and the output shaft of the first speed increaser / reducer 21 should be connected to the driving roller of the first conveyor belt 2. Correspondingly, the output shaft of the second variable-frequency motor 32 should be connected to the input shaft of the second speed increaser / reducer 31, and the output shaft of the second speed increaser / reducer 31 should be connected to the driving roller of the second conveyor belt 3. During use, the staff can adjust the rotation speeds of the first variable-frequency motor 22 and the second variable-frequency motor 32 according to the waste generation speed of the easy-open lid production line, and accelerate or decelerate the rotation speeds of the first variable-frequency motor 22 and the second variable-frequency motor 32 through the first speed increaser / reducer 21 and the second speed increaser / reducer 31, so that the waste conveying speeds of the first conveyor belt 2 and the second conveyor belt 3 match the actual requirements.

[0040] The effects of the above solution are described below:

[0041] This embodiment provides an easy-open lid waste recycling device, which can guide the waste through the first conveyor belt, the second conveyor belt and the material guiding assembly, so that the waste enters the waste basket, facilitating the staff to collect the easy-open lid waste. Secondly, the material guiding assembly in this device can be adjusted in the inclination angle, and the length of the material guiding assembly can be changed according to the change of the inclination angle, so as to adjust the stacking position of the waste in the waste basket and form a uniform stacking effect. In addition, this device can also collect the debris attached to the waste through the filter sieve plate and the debris collection box to prevent the debris from splashing outwards.

[0042] It should be additionally noted that, in order to further improve the automation degree of this device, the staff can also add common action mechanisms (such as electric telescopic rods, pneumatic telescopic rods, hydraulic telescopic rods or driving motors with forward and reverse functions, etc.) to the bracket 1, and correspondingly set common transmission structures (such as link structures, etc.) in the prior art to realize the connection between the action mechanism and the positioning shaft, so as to use the common action mechanism to replace manual driving of the positioning shaft to move inside the guiding notch 11, further improving the use convenience of this device.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
