Description

TECHNICAL FIELD

[0001] The utility model relates to blanking device technical field, more specifically, it relates to automatic packaging machine hopper. BACKGROUND

[0002] Sodium dodecyl sulfate is a white or light yellow organic compound powder, easy to dissolve in water, not sensitive to alkali and hard water, has decontamination, emulsification and excellent foaming power, has slight toxicity to human body, and biodegradability is greater than 90%. In actual production, it is packaged in acicular product, and the weight of single package is 20 or 25 kg, and general non-standard full-automatic quantitative packaging machine of manufacturer is used to complete packaging. The upper end of the equipment is a finished product bin, a transition hopper is connected to the lower opening of the bin to enter the inside of the packaging machine, and the lower opening of the transition hopper in the packaging machine is connected to a linear vibrating screen conveying hopper. In this process, the vibrating block drives the material to move linearly (the vibrating block is composed of a coil and a silicon steel sheet armature), and the linear vibrating screen conveys the material to the next material temporary storage hopper. The material temporary storage hopper is provided with a large and small door to facilitate the control of the weighing accuracy of packaging.

[0003] This kind of blanking form is that the finished product bin of material is freely slid to the linear vibrating screen through the transition hopper, and the material is conveyed to the material temporary storage hopper again, and finally enters the packaging bag. Because the linear vibrating screen is operated in a dusty environment for a long time, plus factors such as material erosion, the vibration block excitation force is insufficient, and abnormal heating occurs, so the failure rate is high, and only frequent maintenance can be carried out, which eventually leads to that the material conveying is not smooth, the accumulation is serious, and even the material is overflowed, which affects the production and has safety hazards. The material bin must be emptied in advance to replace or repair the vibrating block every time the vibrating block fails to cause abnormal feeding, which is a large workload and easy to contaminate the material. When laying the production line, the vibration amplitude of the vibrating block is estimated manually according to the blanking plan of the finished product bin, which leads to that the packaging qualified rate is uncontrollable.

[0019] EMBODIMENT

[0020] The following will be described in detail in combination with the accompanying drawings. Figures 1-5 The utility model will be described in further detail.

[0021] The discharge hopper 5 of the automatic packaging machine is arranged in the complete packaging machine, and the complete packaging machine is composed of at least the finished product bin 1, the closed cabin 2 and the packing unit 3, the three are sequentially communicated, the closed cabin 2 is connected with the material temporary storage hopper 4 inside, the material temporary storage hopper 4 is communicated with the packing unit 3, and the discharge hopper 5 is arranged between the material temporary storage hopper 4 and the finished product bin 1, that is, the discharge hopper 5 is also arranged in the closed cabin 2, and the discharge hopper 5 is simultaneously connected with the finished product bin 1 and the material temporary storage hopper 4. The finished product bin 1 is a funnel type discharge bin, which is used to guide the finished product material object to the discharge hopper 5. The closed cabin 2 serves as a material falling main body and is used to provide a material sliding route. The packing unit 3 includes a packing bag supported and arranged below the material temporary storage hopper 4 in the closed cabin 2 and some full-automatic equipment for automatically binding and packing. Figure 4 And Figure 5 As shown in the figure, the biggest improvement of the complete equipment is that the original transition hopper and linear vibration screen of the packaging machine are optimized into the discharge hopper 5 with smaller occupied space, the material falling route is changed, the space required to be used inside the closed cabin 2 is significantly reduced, and the overall land occupation of the equipment is reduced.

[0022] As shown in the figure, Figures 1-3As shown, the right side of the lower hopper 5 is provided with an inclined slope 6, and the other sides are vertical structures. A straight triangular pad 10 is installed at the bottom of the slope 6, which is fixed and abuts against the slope 6, effectively preventing the slope 6 from deforming and falling due to the point vibration of the subsequent vibration motor 7. A receiving port is provided at the top right of the lower hopper 5, which is connected to the discharge port of the finished material bin 1, so that the material can slide down the slope 6 and fall into the material temporary hopper 4. The discharge port at the bottom of the lower hopper 5 is connected to the top opening of the material temporary hopper 4, ensuring an overlapping part of about 2 cm, which can take advantage of the special nature of needle material, and consider the acceleration of the discharging speed and the avoidance of material overflow. The entire route from the finished material bin 1 to the lower hopper 5 and then to the material temporary hopper 4 is kept sealed. The bottom of the material temporary hopper 4 is an integrated pull seat 9, which is provided with a sliding groove in a certain direction, and a baffle 8 is arranged in the sliding groove. The two ends of the baffle 8 are provided with clamping blocks and are in sliding connection with the sliding groove. Under the premise that the baffle 8 freely slides along the sliding groove, the clamping blocks effectively prevent the baffle 8 from being separated from the sliding groove. A control motor is arranged outside the closed cabin 2 or corresponding to the baffle 8. The control motor drives the baffle 8 to make a simple linear motion and displace along the sliding groove. The control motor and the vibration motor 7 are linked, that is, once the control motor is started, the vibration motor 7 is also started, and once the control motor is stopped, the vibration motor 7 is also stopped. The vibration motor is used to provide vibration force to assist material falling when the material does not flow smoothly. The working mode of the control motor and the vibration motor 7 is to make the material flow only in the time period when the baffle 8 is removed and enters the packing bag of the packing unit 3, that is, the vibration motor 7 can be started to assist the material falling. Avoiding the material not flowing in the stacking state and being affected by the external excitation force to cause the material to be vibrated and compacted. The operation mode of the vibration motor 7 is that the baffle 8 of the material temporary hopper 4 is triggered after being moved away, which is a coarse metering state, and the vibration motor 7 operates at a full frequency of 50 Hz. After the coarse metering is completed, the baffle 8 is appropriately slid back, the discharging speed becomes smaller, and the fine metering state is entered, and the vibration motor 7 operates at a frequency of 35 Hz. After the fine metering is completed, the control motor and the vibration motor 7 are closed at the same time, the baffle 8 is reset, and the material temporary hopper 4 stops discharging to the packing unit 3. Another way is to replace the baffle 8 with a size door design. The full open large door is in a coarse metering state, and the full open small door is in a fine metering state. The opening and closing of the size door are controlled by the control motor. Or combine the two modes and set the size door and the baffle 8. No matter which mode, the discharging speed is fast first and then slow, which not only makes the packing better, but also makes the discharging more efficient, which is better than the original scheme. The whole device structure is simplified, which is more convenient for cleaning material dust, and there is little additional maintenance workload in the future. The packaging precision and operating efficiency are improved. There is no electrical equipment or transmission part directly contacting with the material inside, the material is always transmitted in the closed pipeline, and the whole process does not squeeze the material, effectively protecting the integrity of the material.The modified packaging personnel only participate in the packaging work, and do not need to worry about the speed adjustment of the finished product bin 1.

[0023] It should be noted that the specific embodiments are merely an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the embodiments without creative contribution after reading the specification, but as long as the modifications are within the scope of the claims of the present application, they are protected by the patent law.
