Description

Technical Field

[0001] This utility model belongs to the field of chlorinated paraffin production technology, specifically relating to a quantitative packaging equipment for composite chlorinated paraffin products. Background Technology

[0002] Chlorinated paraffin is a chemical product formed by the chlorination reaction of liquid paraffin with chlorine gas. It possesses advantages such as low volatility, flame retardancy, and electrical insulation, and can be used as a flame retardant, plasticizer, and stabilizer. Compound chlorinated paraffin, also known as a compound chlorinated paraffin stabilizer, is a liquid product typically packaged in drums for sale and transportation. Traditional packaging methods involve manual filling and weighing, resulting in low efficiency, high labor intensity, and high labor costs. Furthermore, human error can easily lead to quantitative errors in product filling. Compared to traditional manual filling methods, existing semi-automatic filling equipment has improved efficiency and reduced labor intensity to some extent. However, manual assistance is still required to place the packaging drums correctly, align the filling head with the drum opening, and then press the foot pedal to begin filling. During the filling process, the finished product is still weighed using a scale. However, dirt and impurities on the weighing platform and the movement of the compound chlorinated paraffin liquid within the drum can easily cause deviations in the measurement results. Therefore, it is essential to further improve the automation level of existing semi-automatic filling equipment. Utility Model Content

[0003] In response to the above situation, this utility model provides a quantitative packaging equipment for composite chlorinated paraffin products, which has a higher degree of automation and can automatically complete the conveying and feeding of packaging barrels, positioning and alignment, quantitative filling and conveying and unloading, eliminating the need for manual operation and reducing labor costs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quantitative packaging device for compound chlorinated paraffin products includes packaging barrels and a conveyor for transporting the packaging barrels. The conveyor is a roller conveyor with a filling station in the middle for filling the packaging barrels with the compound chlorinated paraffin product. The filling station includes a filling device located above the conveyor and a positioning device located below the conveyor. The filling device includes a filling box and a filling head, as well as a lifting assembly for driving the filling head to move up and down. The filling head is vertically and vertically positioned outside the filling box via the lifting assembly. The upper end of the filling head is connected to a liquid supply pipe via a retractable flexible hose. A control valve and a flow meter are installed on the liquid supply pipe, and the inlet end of the liquid supply pipe is connected to a finished product storage tank. The positioning device includes a barrel-blocking assembly for preventing the packaging barrels from continuing to move on the conveyor and a barrel-rotating assembly for rotating the packaging barrels so that their openings are aligned with the filling head.

[0006] Furthermore, the lifting assembly includes a filling cylinder installed on the right side wall of the filling box, and a lifting platform connected to the lower end of the piston rod of the filling cylinder. The filling head is mounted on the lifting platform, and the upper end of the filling head passes vertically through the lifting platform and is fixedly connected to the lifting platform.

[0007] Furthermore, the upper part of the injection head is vertically connected to the front of the lifting platform, and two linear guide rods are vertically arranged on the front and rear sides below the injection cylinder. The lifting platform is slidably connected to the two linear guide rods through two linear bearings, which prevents the lifting platform and injection head from rotating laterally during the up-and-down extension and retraction of the piston rod of the injection cylinder, and plays a guiding and positioning role in the lifting and lowering of the injection head.

[0008] Furthermore, the barrel-blocking assembly includes a blocking cylinder installed below the conveyor and a blocking block connected to the upper end of the piston rod of the blocking cylinder. The blocking block can be raised and lowered to block the packaging barrel directly behind its travel path. The piston rod of the blocking cylinder extends upward from between two adjacent rollers of the conveyor.

[0009] Furthermore, the barrel-blocking assembly also includes an inductive switch mounted on a frame on one side of the conveyor, capable of sensing whether there are packaging barrels at the filling station, thereby controlling the action of the blocking cylinder; after the inductive switch detects that a packaging barrel has entered the filling station, the blocking cylinder pushes the blocking block to rise and block the packaging barrel. At the same time, a signal is sent to the electrical control box, and after a certain delay, the conveyor motor is temporarily stopped.

[0010] Furthermore, the rotating drum assembly includes two sets of rotating drum wheels symmetrically arranged on the left and right sides, which can be opened and closed to clamp the packaging drum. Each set of rotating drum wheels includes two rotating drum wheels and a carrier box. A vertical spindle is coaxially fixed below the center of each of the two rotating drum wheels. The lower part of the two vertical spindles is rotatably connected to the carrier box through bearings. A rotating drum motor is fixedly installed below at least one of the carrier boxes. The rotating drum motor is synchronously driven and connected to the two vertical spindles through a transmission assembly. The two carrier boxes are respectively screwed to both ends of the same bidirectional lead screw. A clamping motor is fixedly installed on one side of the conveyor. The output end of the clamping motor is driven and connected to one end of the bidirectional lead screw.

[0011] Furthermore, the rotating drum assembly also includes an identification switch installed on the upper side of the filling head, used to identify whether the opening of the packaging drum below it is directly below the filling head, thereby realizing interlocking control of the clamping motor and the rotating drum motor. The identification switch can be set to a certain identification distance. Only when the opening of the packaging drum rotates to be directly below the identification switch and the detection distance exceeds the set identification distance, is it considered that the opening of the packaging drum is in position.

[0012] Furthermore, an electrical control box for controlling the entire equipment is provided on the side of the filling box. The electrical control box is equipped with an operation panel and an automatic control system. The induction switch, blocking cylinder, conveying motor, identification switch, clamping motor, rotating drum motor, filling cylinder, control valve and flow meter are all electrically connected to the electrical control box.

[0013] This utility model also includes other components that enable its normal use, all of which are conventional means in the field. In addition, devices or components not limited in this utility model, such as roller conveyors, finished product storage tanks, packaging barrels, filling heads, bidirectional lead screws, control valves, flow meters, electrical control boxes and their automatic control systems, etc., all adopt existing technologies in the field.

[0014] The beneficial effects of this utility model are as follows:

[0015] Compared to existing semi-automatic filling equipment, this quantitative packaging equipment for compound chlorinated paraffin products has a higher degree of automation. It can realize fully automatic packaging operations such as conveying and feeding packaging barrels, positioning and alignment, quantitative filling, and conveying and unloading, eliminating the need for manual assistance. It can completely "replace people with machines", improving work efficiency and reducing labor costs. At the same time, the use of flow metering instead of existing weighing metering further improves the metering accuracy of quantitative filling of compound chlorinated paraffin products.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0021] It should be noted that the terms "up," "down," "front," "back," "left," "right," "inner," and "outer," which indicate directions or positional relationships, are based on the attached drawings and are used only for ease of description.

[0022] Example 1

[0023] like Figure 1-3 As shown, a quantitative packaging device for compound chlorinated paraffin includes a packaging barrel 1 and a conveyor 2 for conveying the packaging barrel. The conveyor is a roller conveyor, and a filling station is set in the middle of the conveyor for filling the packaging barrel with the compound chlorinated paraffin product. The roller conveyor is prior art and will not be described in detail here.

[0024] The filling station includes a filling device positioned above the conveyor and a positioning device positioned below the conveyor. The filling device includes a filling tank 3 and a filling head 4, as well as a lifting assembly for driving the filling head to move up and down. The filling head is vertically mounted outside the filling tank via the lifting assembly. The upper end of the filling head is connected to a liquid supply pipe 6 via a retractable hose 5. A control valve 7 and a flow meter 8 are installed on the liquid supply pipe. The inlet end of the liquid supply pipe is connected to a composite chlorinated paraffin finished product storage tank. The composite chlorinated paraffin finished product storage tank, as well as the control valve, flow meter, liquid supply pipe, and retractable hose, are all existing technologies and will not be described in detail here.

[0025] According to the conveyor's conveying direction (i.e., the direction of travel of the packaging barrel), the positioning device includes a barrel-blocking assembly for preventing the packaging barrel from continuing to travel on the conveyor, and a barrel-rotating assembly for rotating the packaging barrel so that its opening is aligned with the filling head. The packaging barrel has a circular barrel-shaped structure, with a barrel lid 101 on the top, a barrel opening 102 on one side of the lid, and a vent 103 on the other side of the lid. The diameter of the vent 103 is smaller than the diameter of the barrel opening, and the distance from the center of the vent 103 to the center of the lid is smaller than the distance from the center of the barrel opening to the center of the lid. This packaging barrel is existing technology and will not be described in detail here.

[0026] Specifically, the lifting assembly includes a filling cylinder 9 installed on the right side wall of the filling tank, and a lifting platform 10 connected to the lower end of the piston rod of the filling cylinder. The lifting platform is a horizontal flat plate. The filling head is mounted on the lifting platform. The filling head is a section of vertical round tube with a sloping opening at its lower liquid outlet and an external thread on its upper outer side wall. The upper end of the filling head passes vertically through the lifting platform and is fixedly connected to the lifting platform by two locking nuts.

[0027] The upper part of the injection head is vertically connected to the front of the lifting platform. Two linear guide rods 11 are vertically arranged on the front and rear sides below the injection cylinder. The lifting platform is slidably connected to the two linear guide rods through two linear bearings 12, which prevents the lifting platform and injection head from rotating laterally during the up and down extension and retraction of the piston rod of the injection cylinder, and plays a guiding and positioning role in the lifting and lowering of the injection head.

[0028] Specifically, the barrel-blocking assembly includes a blocking cylinder 13 installed below the conveyor and a blocking block 14 connected to the upper end of the piston rod of the blocking cylinder. The blocking block uses a nylon wheel to reduce friction with the packaging barrel. It is rotatably mounted on the upper end of the piston rod of the blocking cylinder via a rolling bearing. The blocking block can rise and fall to block the packaging barrel directly behind it in the path of travel. The piston rod of the blocking cylinder extends upward between two adjacent rollers of the conveyor. When the blocking cylinder extends, the blocking block rises to block the packaging barrel; when the blocking cylinder retracts, the blocking block descends below the conveyor roller surface, without obstructing the continued movement of the packaging barrel.

[0029] The barrel-blocking assembly also includes an inductive switch 15 mounted on a frame on one side of the conveyor. This switch can sense whether there are packaging barrels at the filling station, thereby controlling the movement of the blocking cylinder. The inductive switch is a reflective photoelectric switch. When the inductive switch detects a packaging barrel entering the filling station, the blocking cylinder pushes the blocking block to rise and block the packaging barrel. At the same time, a signal is sent to the electrical control box, and after a 3-second delay, the conveyor motor 32 is temporarily stopped, thus pausing the movement of the packaging barrel and reducing the pushing pressure on the blocking block.

[0030] Specifically, the rotating drum assembly includes two sets of rotating drum wheels arranged symmetrically on the left and right, which can be opened and closed to hold the packaging drum. Each set of rotating drum wheels includes two rotating drum wheels 16 and a carrier box 17. The rotating drum wheels are made of rubber to increase the friction between them and the packaging drum. A vertical spindle 18 is coaxially fixed below the center of each of the two rotating drum wheels. The lower part of the two vertical spindles is rotatably connected to the carrier box through a bearing 19. A rotating drum motor 20 is fixedly installed below the carrier box of one of the two sets of rotating drum wheels as the driving wheel set, while the other carrier box is not equipped with a rotating drum motor and serves as the driven wheel set. The rotating drum motor is synchronously connected to the two vertical spindles via a transmission gear set 21. That is, the carrier box actually adopts a one-to-two double-output gearbox. The two carrier boxes are respectively screwed to both ends of the same bidirectional lead screw 22. A clamping motor 23 is fixedly installed on one side of the conveyor, and the output end of the clamping motor is connected to one end of the bidirectional lead screw. Furthermore, guide rails 24 are also provided on the front and rear sides of the carrier box. The carrier box slides with the two guide rails via a linear slider 25, which guides the reciprocating movement of the carrier box.

[0031] The rotating drum assembly also includes an identification switch 26 installed on the upper side of the filling head, used to identify whether the opening of the packaging drum below it is directly below the filling head, thereby realizing interlocking control of the clamping motor and the rotating drum motor. The identification switch uses an ultrasonic ranging sensor, and the identification switch can be set to a certain height identification distance. Only when the opening of the packaging drum rotates to be directly below the identification switch and the detection distance exceeds its set identification distance can it be determined that the opening of the packaging drum is in position, and then the filling head can begin filling the compound chlorinated paraffin product.

[0032] An electrical control box 27 for controlling the entire equipment is installed on the side of the filling tank. The control box is suspended on the outer wall of the filling tank via a connecting cantilever 28. The control box has an operation panel with a touch screen 29, control buttons 30, and an alarm 31. The control box contains a PLC (not shown) and its associated automated control system. The inductive switch, blocking cylinder, conveying motor, identification switch, clamping motor, rotating drum motor, filling cylinder, control valve, and flow meter are all electrically connected to the control box. The control valve is an electrically operated valve used to control the flow of the compound chlorinated paraffin liquid in the supply pipe. The flow meter is an electronic flow meter used to measure the flow rate of the compound chlorinated paraffin liquid flowing through the supply pipe in real time. The flow meter sends a metering signal to the control box, which then automatically controls the opening and closing of the control valve, thus achieving quantitative filling of the compound chlorinated paraffin product. Compared to weighing, flow measurement offers higher accuracy. The electrical control box and its internal control circuit settings, as well as the automatic control system and automatic control program, all adopt existing technologies and will not be described in detail here.

[0033] Example 2

[0034] like Figure 4 As shown, the only difference from Embodiment 1 is that the two carrier boxes of the two sets of rotating drums in the rotating drum assembly are equipped with rotating drum motors. Each of the two rotating drum motors is synchronously connected to the vertical spindle of the two sets of rotating drums through a transmission gear set. The two rotating drum motors also rotate synchronously. Both sets of rotating drums are active wheel sets, which work together to complete the rotation adjustment of the opening position of the packaging drum.

[0035] The technical solution of this utility model is not limited to the specific embodiments described above. Without departing from the scope and spirit of the described embodiments, many modifications and changes will be obvious to those skilled in the art. Any technical modifications made within the spirit and principles of this utility model shall fall within the protection scope of this utility model.
