Description

Technical Field

[0001] The invention relates to the field of adhesive tape production, in particular to an adhesive tape transmission device with circulating water cooling and a cooling method. Background Art

[0002] Adhesive tape refers to paper with sticky glue on the back. It is different from ordinary paper and is generally used for printing and publicity. It can be pasted on the surface of other objects after printing. Therefore, it is widely used in the publicity industry. It also has waterproof function, which makes it have a long outdoor service life.

[0003] Chinese invention patent CN110817517B discloses a device for cooling and shaping medical packaging coated paper after pressing and forming, comprising a base plate, a lifting device, a locking and positioning device, a transmission device and a winding device. Support plates are symmetrically installed on the left and right ends of the base plate, a flat plate is installed on the support plate, a winding device is installed on the left end of the flat plate, a lifting device is installed between the inner walls of the support plates, a transmission device is installed on the lifting device, and a locking and positioning device is installed on the outer wall of the right end support plate. The present invention can solve the following problems existing in the transmission of existing medical packaging coated paper after pressing and forming: first, when traditional coated paper is transmitted, the coated paper needs to be transported to the cooling machine by a transmission machine, and can only be wound after being cooled by the cooling machine; second, the traditional transmission machine cannot adjust the height of the transmission roller during transmission, and cannot tighten the coated paper in time when it is loose. The coating paper can be cooled while being transmitted.

[0004] After the adhesive tape is produced on the production line, glue liquid will be brushed or sprayed on one side. Some types of glue liquid can only become liquid after heating, causing the heat of the sprayed or brushed glue liquid to be transferred to the adhesive tape, causing the adhesive tape to deform due to heat, thereby causing the deformation of the adhesive tape and resulting in reduced quality. Therefore, a cooling device is required for cooling; the existing adhesive tape transmission device uses electric air cooling equipment for cooling. Air cooling results in low cooling efficiency per unit area, and multiple electric air cooling devices are required for cooling. As a result, a large amount of electricity is consumed in the long-term production process of adhesive tape, which increases the cost of producing adhesive tape. Summary of the Invention

After the coolant is injected into the cooling box, the water pump is started to inject the coolant into the first water cooling groove, thereby cooling the cooling plate to absorb the heat on the adhesive paper, and then the heated coolant enters the second water cooling groove along the third water pipe and is atomized and sprayed out by the nozzle, thereby contacting the air during the falling process, so that the coolant and the air exchange heat and cool down, and then descend along the cooling box to gather and complete the circulation cooling, thereby utilizing the air for cooling and realizing the function of saving electricity; solving the problem of high energy consumption caused by the use of a large number of electric cooling tools in the existing adhesive paper production line.

[0008] An inclined baffle is fixedly connected in the cooling box; a filter baffle is placed on the inclined baffle; a plurality of guide plates are fixedly connected at intervals in the cooling box; a drop groove is provided in the guide plate; during operation, the inclined baffle makes it easy to install and disassemble the filter baffle, and the filter baffle allows the coolant to be filtered out after being adsorbed into the air during the heat exchange and cooling cycle in the air, thereby reducing the wear on the water pump and extending the service life of the water pump and the pipeline; and solves the problem of high energy consumption of the existing method of cooling electric equipment with adhesive tape on the assembly line.

[0009] The transmission unit includes a winding shaft, a first motor and a frame; the frame is fixedly connected to the lower end of the cooling plate; a winding shaft is rotatably inserted in the frame; one end of the winding shaft is fixedly connected to the first motor; the lower end of the first motor is fixedly connected to the motor base; the motor base is fixedly connected to the side of the frame; when working, the first motor is energized and rotated, thereby driving the winding shaft to rotate, thereby realizing the function of winding the adhesive paper after lamination, and can serve as a part of the structure of the transmission line to support the passage of the adhesive paper.

[0010] A second motor is fixedly connected to the motor base; a support roller is symmetrically connected and rotated in the frame; one end of the support roller is fixedly connected to the second motor; a conveyor belt is sleeved on the support roller; second air holes are evenly distributed on the conveyor belt; a plurality of shaping shafts are symmetrically connected to the frame for clamping the conveyor belt for rotation; when working, a depression is generated at the upper end of the conveyor belt through the four shaping shafts, which can be used to fix the cooling plate, thereby ensuring that the upper surface of the cooling plate is flush with the upper surface of the conveyor belt, so that the adhesive paper can always remain horizontal when moving on the transmission unit and the circulating cooling unit, so that the adhesive paper will not produce greater deformation during the cooling process; it solves the problem that when the existing transmission unit is connected to the cooling unit, the shape of the adhesive paper during transportation is changed, which is prone to greater deformation.

[0012] A cooling method for a tape conveying device with circulating water cooling, which is applicable to any of the above-mentioned tape conveying devices with circulating water cooling, comprises the following steps:

[0013] S1: First, assemble all the components, then fill the cooling box with coolant, power on and start the water pump, so that the coolant in the cooling box flows along the second water pipe and the first water pipe into the first water cooling tank, then flows along the third water pipe into the second water cooling tank, and then is sprayed out through the nozzle in atomized form;

[0014] S2: The droplets sprayed by the nozzle undergo a large-area heat exchange with the air, then fall under the action of gravity and come into contact with the upper surface of the guide plate. They then slide along the drop trough and move downward on the inner surface of the cooling box. They are then filtered through the filter baffle and return to the bottom of the cooling box.

[0015] S3: Then the first motor and the second motor are powered on to rotate, driving the reel and the support roller to rotate, thereby driving the adhesive paper wrapped on the reel to continuously pass through the circulating cooling unit to complete cooling and then be reeled. At the same time, the negative pressure pump is powered on to work, so that the hot air of the adhesive paper passing through the circulating cooling unit is taken away.

[0016] The present invention provides a tape conveying device and cooling method with circulating water cooling, which has the following features:

[0017] Beneficial effects:

[0018] 1. The present invention uses a transport unit to move heated adhesive tape, which then passes over a cooling plate during transport. After coolant is injected into the cooling box, a water pump is activated to inject the coolant into the first water cooling tank, thereby cooling the cooling plate and absorbing the heat from the adhesive tape. The heated coolant then flows through a third water pipe into the second water cooling tank and is atomized and sprayed out by a nozzle. As it falls, it comes into contact with the air, exchanging heat with the air and cooling it. The coolant then descends through the cooling box and collects to complete a cyclic cooling process, thereby utilizing air for cooling and saving electricity. This solves the problem of high energy consumption caused by the large number of electric cooling tools used in existing adhesive tape production lines.

[0019] 2. The present invention facilitates the installation and disassembly of the filter baffle by tilting the baffle. Impurities adsorbed by the coolant in the air during the heat exchange and cooling cycle in the air can be filtered out through the filter baffle, thereby reducing the wear on the water pump and extending the service life of the water pump and pipeline; and solves the problem of high energy consumption of the existing method of cooling electric equipment with adhesive tape on the assembly line.
