Description

Technical Field

[0001] The present invention relates to a cleaning machine, in particular to a lifting cleaning tank type basket conveyor cleaning machine using chain transmission. Background Art

[0002] In ultrasonic cleaning and other water bath immersion cleaning methods, since the workpieces are immersed in water for cleaning, there are no dead corners in the 360° all-round cleaning. However, there are inevitably dead corners in spray cleaning. Therefore, cleaning machines with water bath immersion cleaning and ultrasonic cleaning are cleaner and more popular. However, the workpiece conveyor belt must gradually descend into and out of the water bath cleaning section and the ultrasonic cleaning section of the water tank, and then gradually rise to be transmitted out of the water bath cleaning tank and the ultrasonic cleaning tank. The belt transmission is complex, and the equipment manufacturing cost is high, especially the equipment is too long and the workpieces are prone to disorder.

[0003] For example, in 201120399806.4, an immersion and cleaning integrated device includes an immersion tank and a workpiece cleaning machine connected as a whole. A conveyor belt is provided in the immersion tank, and the conveyor belt extends into the workpiece cleaning machine. The starting end of the conveyor belt is arranged below the liquid level in the immersion tank, and the other end of the conveyor belt gradually rises towards the entrance of the workpiece cleaning machine to transfer the immersed workpieces into the workpiece cleaning machine for cleaning. A spraying mechanism is provided in the immersion tank, and an ultrasonic device is installed in the immersion tank.

[0004] Also, in 201520873078.4, a full-automatic cleaning machine for pouring workpieces for cleaning is composed of a water bath pre-washing section and a belt type cleaning machine connected. The water bath pre-washing section is installed at the front end of the belt type cleaning machine as the workpiece inlet end, and its conveyor belt is connected to the conveyor belt of the slag removal pre-washing section of the belt type cleaning machine or the conveyor belt of the belt type cleaning machine as a whole section.

[0005] Another example is that the patent ZL201220320085.8 provides a conveyor belt and its rotary mechanism for an automatic transmission continuous cleaning ultrasonic cleaning machine, which is characterized in that it includes a plurality of turning devices and a closed conveyor belt. The conveyor belt surrounds each turning device in the cleaning machine for one week. The installation positions of the turning devices are respectively located at: the upper and lower parts of the cleaning machine inlet, the upper and lower parts of the connection between the spray slag removal section and the ultrasonic cleaning tank, the two ends of the bottom in the ultrasonic cleaning tank, the upper and lower parts of the connection between the ultrasonic cleaning tank and the spray rinsing section, the lower part of the connection between the spray rinsing section and the drying section, and the upper and lower parts of the cleaning machine conveyor belt outlet.

[0006] For another example, Patent ZL202110167519.9 provides a fully automatic basket conveyor with dead - angle - free self - cleaning washing machine, including a cleaning and drying box, characterized in that: no less than 1 cleaning and drying box is installed on one or more closed conveyor chains. The cleaning and drying box follows the conveyor chain and makes a full circle around no less than 2 turning devices in the dead - angle - free self - cleaning washing machine. Driven by the power device, the conveyor chain and the cleaning and drying box circulate in the washing machine. Two turning devices located at the inlet and outlet of the washing machine respectively divide the conveyor chain and the cleaning and drying box into upper and lower layers. The cleaning and drying box follows the upper or lower layer of the conveyor chain and passes through all functional sections of the washing machine. At least one of the top, bottom or side of the cleaning and drying box is provided with a positioning member, and the number of positioning members of each cleaning and drying box is not less than one.

[0007] The above technologies all require technical means such as oblique entry and oblique exit at workstations such as ultrasonic cleaning, bubble cleaning devices, and water flow cleaning. The equipment is relatively long and not suitable for occasions with a small area. Summary of the Invention

[0008] In order to solve the problems of complex conveyor of ultrasonic cleaning machines, high manufacturing cost of equipment, especially long length and large floor area, the present invention provides a dead - angle - free cleaning system of cleaning and drying box type to make up for the deficiencies of the prior art.

[0009] The technical solution of the present invention is: a lifting and cleaning trough-type basket conveyor cleaning machine, which includes a lifting cleaning trough. More than 1 basket is suspended on a closed conveyor chain, and a conveyor power device drives the conveyor chain to circulate. The workpiece inlet, each functional section, and the workpiece outlet are arranged in sequence. All the baskets sequentially pass through the workpiece inlet, each functional section, and the workpiece outlet. And the functional section includes at least 1 water bath cleaning section. At the same time, the cleaning trough of the water bath cleaning section is a lifting cleaning trough; the structure of the lifting cleaning trough includes: the cleaning trough of the water bath cleaning section is arranged on at least 1 lifting device, so that the cleaning trough can be lifted or lowered relative to the machine frame or the ground; the installation method of the lifting cleaning trough on the lifting device includes: the base of the lifting device is installed on the machine frame or installed on the ground, and the lifting component is connected to the lifting cleaning trough; or, the base of the lifting device is installed on the lifting cleaning trough, and the lifting component is connected to the machine frame or installed on the ground; the length and width of the lifting cleaning trough are greater than the length and width of the basket, and its depth is equivalent to or deeper than the height of the basket, so that it is sufficient to accommodate at least 1 basket; after the lifting cleaning trough descends, its upper edge is not higher than the bottom of the basket. This position is the highest position where the lifting cleaning trough descends. Usually, the lifting cleaning trough should continue to descend by 1-10 cm to ensure that the basket runs smoothly on the closed conveyor chain and will not scrape against the lifting cleaning trough; after the lifting cleaning trough rises, most or all of the basket is immersed in the lifting cleaning trough, so that the water bath cleaning can play a cleaning role on the tableware or workpieces in the basket. This position is the lowest position where the lifting cleaning trough rises. Usually, the lifting cleaning trough should continue to rise by 1-10 cm to ensure that all the tableware or workpieces in the basket are immersed in the lifting cleaning trough to achieve a good cleaning effect.

[0010] The conveyor chain surrounds a circulating suspension rail and a turning device for one week, and its running track is a closed ring, thereby dividing the baskets into upper and lower layers, and circulating under the drive of the conveyor power device, forming a circulating basket suspension rail operation system. The number of the conveyor chains is usually 2, and the baskets are suspended between the 2 conveyor chains to ensure stable operation; the bottom of the basket is in a grid or porous structure, which is convenient for spraying or passing through bubble water flow and ultrasonic penetration cleaning; usually, a plurality of thorns or a plurality of grids and other workpiece positioning devices are provided to carry workpieces or tableware, so that the workpieces or tableware can be kept in position during the cleaning and conveying process; the surrounding is usually a plate, or it is also a grid or porous structure, and its shape includes: square, rectangle, etc.

[0011] The ways in which the hanging baskets penetrate through the functional sections and the work-piece inlet and outlet stations include the following three types: First, the lower-layer penetration type, where all stations are arranged at the lower layer and both ends of the conveyor chain. The upper layer of the conveyor chain is the return journey for the hanging baskets. The hanging baskets follow the lower layer of the conveyor chain through each station, and at least one side of both sides of the work-piece inlet and work-piece outlet is open. Second, the upper-layer penetration type, where all stations are arranged at the upper layer and both ends of the conveyor chain. The hanging baskets follow the upper layer of the conveyor chain through each station, and the lower layer of the conveyor chain is the return journey for the hanging baskets. Third, the three-dimensional type, where the stations are sequentially arranged on the upper and lower layers of the conveyor chain respectively, and the hanging baskets follow both the upper and lower layers of the conveyor chain through each station.

[0012] All the hanging baskets have the same distance between each other, and their cyclic operation modes include: intermittent conveying or continuous conveying.

[0013] The intermittent conveying includes: after the hanging basket conveys one conveying section from one station to the next station, it stops for a period of time and then continues to convey one conveying section. The lengths of all functional sections and the inlet and outlet are all one conveying section or an integer multiple thereof, so as to ensure that when the hanging baskets are conveyed, each hanging basket reaches the corresponding functional section or the corresponding position simultaneously; the conveying section is: the hanging baskets are installed on the conveyor chain at the same interval, and the distance between adjacent hanging baskets on the conveyor chain is one conveying section, and each hanging basket stops at one of the stations when it stops.

[0014] Under the control of the control system, during the stop time of each hanging basket at the corresponding station, the operation modes or operation sequences of the corresponding mechanisms include: First, the lifting device in the water bath cleaning section drives the cleaning tank to rise, so that the hanging baskets in the water bath cleaning section are immersed in the cleaning tank, and the water bath cleaning function is started at this time, or the water bath cleaning is always started during the conveying operation and stop. Second, the rest of the functional sections are started at this time or are always started. Third, work-pieces are respectively placed and taken out at the work-piece inlet and outlet. After the work-pieces are placed and taken out and each functional section works for a certain period of time, the lifting device drives the cleaning tank to descend, and the conveying power device drives the conveyor chain to drive the hanging baskets to continue to convey forward for one conveying section. Each hanging basket reaches the next station simultaneously, and then continues to operate according to the above rules;

[0015] For the continuous operation, its operation mode is: when the hanging basket reaches above the lifting type cleaning tank, the lifting type cleaning tank starts to rise, and when the hanging basket leaves above the lifting type cleaning tank, the lifting type cleaning tank starts to descend, that is, the length of the lifting type cleaning tank needs to be longer. When the hanging basket runs to the water bath cleaning section, it runs in the lifting type cleaning tank and remains immersed in the lifting type cleaning tank, greatly extending the cleaning time and improving the cleaning efficiency.

[0016] The highest position where the lifting cleaning tank ascends and the lowest position where it descends are respectively provided or not provided with a lifting limit switch and a descending limit switch. All the limit switches are electrically connected to the cleaning machine control system or the lifting device. When the lifting cleaning tank descends to a predetermined position where the upper edge of the lifting cleaning tank is lower than the bottom of the hanging basket, the descending limit switch senses that the lifting cleaning tank has descended in place, and the lifting device stops descending. When the lifting cleaning tank ascends to a predetermined position where most or all of the hanging basket is immersed in the lifting cleaning tank, the lifting limit switch senses that the lifting cleaning tank has ascended in place, and the lifting device stops ascending. And when necessary, it is set that when the descending limit switch does not sense that the lifting cleaning tank has descended in place, that is, the lifting cleaning tank has not descended to the predetermined position where the upper edge of the lifting cleaning tank is lower than the bottom of the hanging basket, the transmission power device for driving the conveyor chain and the hanging basket does not start, which can prevent the hanging basket from colliding with the lifting cleaning tank.

[0017] When necessary, the lifting cleaning tank or the lifting device is provided with guide columns or guide rails to keep the lifting cleaning tank stable during ascending and descending and avoid shaking.

[0018] At least one of the following cleaning devices is provided in the water bath cleaning section: 1. Ultrasonic cleaning device; 2. Bubble cleaning device; 3. Water flow cleaning device. The ultrasonic cleaning device consists of an ultrasonic transducer or an ultrasonic vibration plate and an ultrasonic generator. The number of ultrasonic transducers is not less than 1 and is installed at least at one position on the bottom and side of the cleaning tank, or the ultrasonic vibration plate is installed at least at one position on the bottom and side inside the cleaning tank. All the transducers or the ultrasonic vibration plate are electrically connected to the ultrasonic generator. After the cleaning tank rises, the hanging basket and the tableware or workpieces in the hanging basket are immersed in the water in the ultrasonic cleaning tank, and through the cleaning effect of ultrasonic waves, 360° dead - angle - free cleaning can be achieved.

[0019] The bubble cleaning device consists of an air pump and nozzles or air outlets, etc. The water flow cleaning system consists of a water pump and nozzles or water outlets, etc. The installation positions of the nozzles, water outlets, and air outlets include one or more positions on the bottom and side of the cleaning tank.

[0020] Because the lifting cleaning tank moves up and down, usually, the connecting pipes connecting the nozzles or air nozzles or water outlets of the lifting cleaning tank to the air outlet pipe of the air pump and the water pipe of the water pump are connected by hoses with sufficient length, and the wires connecting the ultrasonic cleaning device are also of sufficient length to ensure enough length and prevent damage due to pulling.

[0021] In addition to the water bath cleaning section, it usually also includes functional sections such as a spray pre-washing section, a spray rinsing section, and a drying and disinfection section. The spray pre-washing section is located at the front end and usually has a slag filtering device due to a large amount of residue. The spray rinsing section is located after the water bath cleaning section. The drying and disinfection section may or may not be equipped with a drying device. The spray pipes and nozzles of the spray pre-washing section and the spray rinsing section are installed above and below the hanging basket at their respective workstations and are oriented towards the inside of the hanging basket. The usual arrangement order of each functional section includes: workpiece inlet, spray pre-washing section, water bath cleaning section, spray rinsing section, drying and disinfection section, workpiece outlet.

[0022] The types of the lifting device include: a lead screw slider lifting mechanism, an electric push rod, a cylinder mechanism, a sprocket chain transmission mechanism, a gear rack mechanism, a worm gear mechanism, a hydraulic mechanism, and a link structure. The lifting component of the lifting device is connected to at least one of the upper part, the side part, and the bottom part of the cleaning tank. The lifting component includes: the slider of the lead screw slider lifting mechanism, a sprocket of the sprocket chain transmission mechanism, the rack of the gear rack mechanism, the worm of the worm gear mechanism, the piston of the cylinder mechanism, the piston of the hydraulic mechanism, and the hinge of the link mechanism. The lead screw of the lead screw slider lifting mechanism, the sprocket of the sprocket chain transmission mechanism, the gear of the gear rack mechanism, the worm of the worm gear mechanism, the cylinder body of the cylinder mechanism, and the cylinder body of the hydraulic mechanism are usually connected to the power mechanism or the machine frame, and a link mechanism can also be used for lifting. When two lifting components are respectively installed on both sides of the cleaning tank and are driven by one power mechanism, a synchronizing device may or may not be installed between the lifting devices on both sides. Installing the synchronizing device can ensure the balance of the cleaning tank during lifting, prevent it from tilting or jamming, and greatly increase the stability of the equipment. The synchronizing device includes: 2 pairs of bevel gears, a chain, and 2 sprockets, etc., which are respectively connected to the two lifting components on both sides of the cleaning tank.

[0023] When there are multiple immersion cleaning sections, two or more water bath cleaning sections share the same lifting device and rise and fall simultaneously, or each has an independent lifting device.

[0024] All the water bath cleaning devices are immersion cleaning, and the water flow, bubbles, or ultrasonic cleaning is all oriented towards the workpieces inside the hanging basket. Through the water immersion, bubble, or water flow cleaning system, the workpieces are washed and scoured, and the grease and residue on the workpieces are greatly reduced. Or ultrasonic waves are used to perform ultrasonic cleaning and emulsify the grease on the tableware or workpieces. Therefore, there are no dead corners during cleaning and the cleaning effect is good. In particular, there is no conveyor belt for tableware or workpieces to enter and exit the water bath cleaning section and the ultrasonic cleaning section, so there is no need to gradually lower or raise to enter and exit the cleaning tank, avoiding the confusion of tableware or workpieces and reducing the length of the equipment.

[0025] The present invention is used for cleaning various workpieces, tableware, etc. Its advantages are obvious. It can avoid the inclined entry and exit in the water bath cleaning section, prevent tableware or workpieces from being disordered. The tableware and workpieces in the hanging basket are fully positioned and automatically kept horizontal during operation, ensuring that the tableware or workpieces are cleaned thoroughly and dried completely, and occupying less floor space, greatly reducing the site requirements of the equipment.
