Description

Technical Field

[0001] The invention relates to the technical field of cookware manufacturing, and in particular to an adsorption device for a cooking container plate and a use method thereof. Background Art

[0002] Cooking containers are very common kitchen utensils and are an important tool that people cannot do without when making delicious food. The most frequently used ones are woks, stew pots, pressure cookers and other pots. These pots are stamped during the production process. Before stamping, the raw materials for producing cooking containers are basically plates. During the transportation of these plates, adsorption equipment will be used to fix them. Existing adsorption equipment basically uses a pump air machine to provide negative pressure for the suction cup to fix the plate. This type of adsorption and transportation equipment has the advantages of simple structure, easy use and stable operation. It is currently the manufacturing equipment for cooking containers with the widest range of applications.

[0003] Although the existing cooking container manufacturing equipment has the above-mentioned advantages, there are still certain limitations in the actual use process. There is only one adsorption device in the traditional equipment, which requires the power device to drive the adsorption device to reciprocate during use, thereby reducing production efficiency. At the same time, in order to make the suction force generated by the suction cup more balanced, multiple suction cups are installed at the bottom of the device. Once some suction cups are not in contact with the plate, the external gas can enter the interior of the adsorption device, resulting in reduced suction of other suction cups, resulting in the problem of failure to fully fix the plate. In this regard, the present application document proposes an adsorption device for cooking container plates and a method of use, aiming to solve the above-mentioned problems.

[0011] Preferably, the output end of the controller is connected to the input end of the telescopic machine by means of a signal connection.

[0012] The present invention has the following beneficial effects:

[0013] 1. The present invention has a lifting device fixedly installed on the outer surface of the rotating seat. The number of the lifting devices is three and they are distributed in a circular array. A travel bracket is fixedly installed on one side of the lifting device, so that the device can continuously transport the plates used for processing the cookware by unidirectional rotation. Since the traditional equipment has only one transportation device, the plates must be transported in a round trip manner, which leads to a problem of reduced transportation efficiency. The present device avoids this problem well and improves the production efficiency of the device.

[0014] 2. The present invention has a travel sleeve fixedly installed at the bottom of the fixed seat, and a fixed sleeve movably installed on the outer surface of the travel sleeve. The fixed sleeve is fixedly installed on the bottom of the inner cavity of the travel bracket, so that the lifting device controls the travel bracket to move in the vertical downward direction until the bottom of the suction cup contacts the plate. At this time, the telescopic machine drives the connecting seat and the travel plate to move in the vertical upward direction. At this time, the fixed seat is fixedly connected with the circular through hole I opened on the top of the travel plate, thereby driving the travel sleeve to be pulled out of the fixed sleeve, so that the inner cavity volume of the travel sleeve and the fixed sleeve becomes larger, resulting in a decrease in air pressure, thereby sucking the plate and then transporting it. Compared with traditional equipment, this type of transportation and placement does not require external pump air The machine provides adsorption force, thereby reducing the use cost of the device. At the same time, the adsorption devices that provide adsorption force for the suction cups are independent of each other. When some suction cups are not in contact with the plate, it does not affect the adsorption force generated by other suction cups. Traditional equipment provides adsorption force through a pump air machine. When some suction cups are in contact with the plate, the external gas will enter the interior of the equipment through the suction cup, resulting in a decrease in the adsorption force generated by the pump air machine, resulting in the problem of the plate falling off during transportation. The device avoids this problem well and improves the stability of the device during transportation. In addition, the device can adsorb and transport plates of any size, thereby improving the practicability of the device.

[0015] 3. The present invention has a circular through hole II at the top of the limit sliding seat, and an adjusting resistor rod is movably sleeved inside the circular through hole II, so that the operator can change the length of the adjusting resistor rod between the travel slider and the limit sliding seat by pushing the adjusting resistor rod, thereby changing the resistance value of the adjusting resistor rod incorporated into the circuit. When the height of the telescopic machine control connecting seat and the travel plate changes, the contact position of the brush and the fixed resistor rod changes synchronously, thereby changing the resistance value of the fixed resistor rod incorporated into the circuit synchronously. At this time, the adjusting resistor rod and the fixed resistor rod are connected to the controller through the line and the resistance value of the adjusting resistor rod and the fixed resistor rod connected to the line is identified, so that when the resistance value of the fixed resistor rod incorporated into the circuit is the same as the resistance value of the adjusting resistor rod incorporated into the circuit, the output end of the controller is connected to the input end of the telescopic machine through a signal connection, and the telescopic machine is controlled to stop, so that the device can conveniently adjust the adsorption force generated by the adsorption device and the suction cup, thereby improving the practicality of the device.

[0016] 4. The present invention makes the pressure-stabilizing hole I and the pressure-stabilizing hole II correspond to each other in the longitudinal direction, so that the device can reach the stroke limit through the telescopic machine to control the connecting seat and the stroke plate before use, so that the pressure-stabilizing hole I and the pressure-stabilizing hole II correspond to each other, so that the external gas can enter the interior of the adsorption device, and the air pressure inside the adsorption device is equal to that of the outside, avoiding the problem that the plate cannot be separated normally due to excessive air pressure inside the adsorption device, thereby improving the feasibility of the device.

At this time, the telescopic machine 5 drives the connecting seat 7 and the travel plate 8 to move in the vertical upward direction. At this time, the fixed seat 91 is fixedly connected with the circular through hole I opened on the top of the travel plate 8, thereby driving the travel sleeve 92 to be pulled out of the fixed sleeve 93, so that the inner cavity volume of the travel sleeve 92 and the fixed sleeve 93 becomes larger, resulting in a decrease in air pressure, thereby sucking the plate and then transporting it. Compared with traditional equipment, this transportation and placement does not require an external pump to provide adsorption force, thereby reducing the use cost of the device.

A circular through hole II is opened on the top of the limited sliding seat 123, and an adjusting resistor rod 124 is movably sleeved inside the circular through hole II, so that the operator can change the length of the adjusting resistor rod 124 between the travel slider 125 and the limited sliding seat 123 by pushing the adjusting resistor rod 124, thereby changing the resistance value of the adjusting resistor rod 124 incorporated into the circuit. When the telescopic machine 5 controls the height change of the connecting seat 7 and the travel plate 8, the contact position of the brush 11 and the fixed resistor rod 126 changes synchronously, so that the resistance value of the fixed resistor rod 126 incorporated into the circuit changes synchronously. At this time, by adjusting The section resistor rod 124 and the fixed resistor rod 126 are connected to the controller 121 through the line and identify the resistance value of the circuit part of the adjustable resistor rod 124 and the fixed resistor rod 126, so that when the resistance value of the fixed resistor rod 126 is incorporated into the circuit, it is the same as the resistance value of the adjustable resistor rod 124.
