Technical Field

[0001] The utility model relates to the technical field of blister equipment, in particular to an automatic oil spraying device of a forming blister machine. Background Art

[0002] The blister tray is a packaging product that uses the blister process to make plastic coils with grooves of specific shapes.

When the blister forming machine in the prior art blister forms rolled plastic coils, it can only perform blister forming on one roll of plastic coil at a time. The existing application number is CN201921063070.6, which is a double-layer feeding plastic coil blister forming machine, including a frame, a first feeding mechanism, a second feeding mechanism... Oil is sprayed on the two rolls of plastic coils through an oil spraying mechanism to avoid sticking too tightly and difficult to separate, thereby improving production efficiency; when one roll of plastic coil is stopped from being discharged, the other roll of plastic coil can also be ensured to continue to discharge without delaying production.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5 , an automatic oil spraying device of a forming blister machine, comprising a collecting box 1, a frame 2, an oil outlet pipe 3 and two rows of oil spray heads 6 located at the top and bottom of the oil outlet pipe 3, a pair of oil absorbing strips 16 located on the left and right sides of the oil spray heads 6 are fixedly arranged at the top and bottom of the oil outlet pipe 3, and a recovery device is arranged in the oil absorbing strips 16, and a guard plate 4 welded to the oil outlet pipe 3 is bonded to the end surface of each pair of oil absorbing strips 16 away from each other, and the front and rear ends of the guard plate 4 are welded to the frame 2, and the ends of the upper and lower pairs of oil absorbing strips 16 away from each other are connected to two layers of plastic coils through a rolling connection device.

[0021] The recovery device includes an oil suction pipe 15, fine holes 17, and a water pump 11. The water pump 11 is fixedly installed on the rear end surface of the frame 2. A strip groove is provided on the outer wall of the oil suction strip 16, and the oil suction pipe 15 is bonded in the strip groove. A plurality of fine holes 17 are provided on the outer wall where the oil suction pipe 15 contacts the oil suction strip 16. The rear end of the oil suction pipe 15 is connected to the frame 2 through a connecting device, and the exhaust port of the frame 2 is connected to the collection box 1 through a collecting device.

[0022] The collecting device includes a filter box 12 and a filter plate 13. The filter box 12 is fixedly arranged on the rear end face of the frame 2. An opening for air discharge is provided on the top of the filter box 12, and a filter plate 13 for preventing oil discharge is fixedly arranged at the opening. An inlet and an outlet are respectively provided on the top and the left end face of the filter box 12, and the inlet and the outlet are respectively connected to the water pump 11 and the collecting box 1 through pipes. After the air and oil mixture is drawn into the filter box 12, a small amount of air mixed with the oil is allowed to stand and separate from the oil, and then discharged through the opening, and a small amount of oil carried by the air is filtered by the filter plate 13.

[0023] The injection device includes an oil pump 7. A transverse plate is fixedly provided on the front end surface of the frame 2, and the oil pump 7 is fixedly installed on the transverse plate. The oil inlet and the oil outlet of the oil pump 7 are connected to the collection box 1 and the oil outlet pipe 3 through pipelines respectively.

[0024] The rolling connection device includes a sleeve 5 and a thin shaft 14. The top of the upper oil absorbing strip 16 and the bottom of the lower oil absorbing strip 16 are both provided with arc grooves, and the sleeve 5 with the outer wall rollingly connecting the two layers of plastic coils is rotatably arranged in the upper and lower pairs of arc grooves. The thin shaft 14 is inserted into the sleeve 5, and the two ends of the thin shaft 14 are fixedly connected to the frame 2. The same rolling sleeve 5 reduces the wear on the two layers of plastic coils and avoids scraping the oil on the two layers of plastic coils.

[0025] The connecting device includes a connecting box 8, a connecting elbow 9, and a tee 10. A pair of connecting boxes 8 are fixedly provided on the rear end surface of the back frame 2. The rear ends of the two oil suction pipes 15 located on the left and the rear ends of the two oil suction pipes 15 located on the right of the two pairs of oil suction pipes 15 penetrate the frame 2 and are respectively connected to the left and right connecting boxes 8. The air inlet of the water pump 11 is connected to the tee 10 through a pipeline, and the other two interfaces of the tee 10 are respectively connected to the two connecting boxes 8 through the connecting elbow 9.

[0026] The cross section of each pair of guard plates 4 is arc-shaped, and the inner arc surface is bonded with an arc-shaped oil-absorbing strip 16 on the outer wall that matches with the inner arc surface.

[0027] Working principle: The oil in the collection box 1 is pumped into the oil outlet pipe 3 through the oil pump 7 and then sprayed onto the two layers of plastic coils in atomized form through the oil spray head 6. The oil that is not blocked on both sides and not sprayed onto the two layers of plastic coils due to factors such as air flow and gravity is absorbed by the oil absorption strip 16. The small amount of oil adhered to the sleeve 5 is absorbed by the oil absorption strip 16. When the oil absorbed by the oil absorption strip 16 is too much, the oil is intermittently sucked into the oil absorption pipe 15 through the fine hole 17 through the water pump 11, and then collected and injected into the collection box 1 through the connecting box 8, the connecting elbow 9, and the tee 10. After the air is discharged, it is injected into the collection box 1 under the action of gravity.

[0028] The automatic oil spraying device can not only spray oil on the two layers of plastic coils, but also intercept and absorb the oil that is not sprayed onto the two layers of plastic coils due to factors such as air flow and gravity through the oil suction pipe 15 and the sleeve 5, effectively preventing the atomized oil from diffusing into the air to pollute the factory air and other machines and materials, thereby ensuring factory hygiene, worker health, machine service life and material purity, and can intermittently recover the oil absorbed by the oil absorption strip 16 through the filter box 12, the oil suction pipe 15, etc., saving oil consumption while preventing the oil absorption strip 16 from losing its oil absorption function due to excessive oil absorption.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
