A paper shell auxiliary coloring device

Abstract

The present application relates to the technical field of coloring equipment, and discloses a paper shell auxiliary coloring equipment, in order to solve the problem that the amount of wax water entering the position between adjacent paper shells is small, resulting in the coloring uniformity of the paper shells being affected. The present invention uses the setting of a rotating drum and a clamping piece, and uses the clamping piece to fix the placement box. After that, the wax water is filled into the rotating drum, so that the rotating drum drives the clamping piece and the placement box to rotate circumferentially in the wax water. In this process, the paper shells stacked in the placement box rotate with the placement box, and then are affected by buoyancy and move in sequence. Through this action, the distance between adjacent paper shells is intermittently increased, which makes it easier for the wax water to enter the position between adjacent paper shells, and improves the coloring uniformity of the paper shells.

Description

Technical Field

[0001] The present application relates to the technical field of coloring equipment, and in particular to a paper shell auxiliary coloring equipment. Background Art

[0002] In order to make products more attractive nowadays, the packaging paper shells of products are often colored through coloring equipment, making the color of the paper shells more vivid and improving the corrosion resistance of the paper shells.

[0003] Some existing paper shell coloring equipment is mainly composed of a wax water pool, a placement box (the box body is provided with a through hole) and a moving mechanism. When in use, a number of folded paper shells are placed in the placement box, and then the moving mechanism drives the placement box to intermittently enter the wax water pool, so that the paper shells are intermittently completely immersed in the wax water, and then repeat for a period of time. When the paper shells are fully immersed and colored, the moving mechanism drives the placement box to leave the wax water pool and take out the paper shells. Through the above actions, the coloring operation of the paper shells is completed.

[0004] However, in the process of the above-mentioned moving mechanism driving the placement box to intermittently enter the wax water pool, since several cardboard shells are stacked, when the placement box enters the wax water pool, the cardboard shells in the placement box are blocked by the wax water below, which makes it easier for the cardboard shells to fit together. Afterwards, when the placement box leaves the wax water pool, the wax water above the cardboard shells will also block the cardboard shells. Through the above-mentioned actions, the amount of wax water entering the position between adjacent cardboard shells is less, resulting in the coloring uniformity of the cardboard shells being affected. Summary of the invention

A fixing rod is fixedly installed at the center position of the closing plate, and one end of the fixing rod facing the box cover forms a rotational connection with the center position of the box cover, and the end of the fixing rod facing away from the box cover is fixedly connected to the moving mechanism.

[0009] Furthermore, a telescopic cylinder is fixedly installed at the center position inside the left mounting seat, and a shift plate is provided inside the wax and water chamber and at a position on the side of the clamp facing away from the closing plate. The output rod of the telescopic cylinder extends into the wax and water chamber and is fixedly connected with the shift plate. The diameter of the shift plate is smaller than the diameter of the wax and water chamber.

[0010] Furthermore, the height of the port through which the through hole communicates with the external environment is higher than the height of the uppermost position of the wax-water chamber.

[0011] Furthermore, partition rods are longitudinally and equidistantly arranged in the cavity of the placement box, the partition rods are located between adjacent paper shells, and the spacing between adjacent partition rods is greater than the thickness of the paper shells.

[0012] Furthermore, the partition rod is located in the placement box near the dial plate.

[0013] Furthermore, two ends of the partition rod are fixedly connected to corresponding inner walls of the placement box.

[0014] Furthermore, both ends of the dividing rod extend out of the placement box, and the part of the dividing rod extending out of the placement box forms a sliding connection with the placement box. Both ends of the dividing rod and the positions located in the placement box cavity are fixedly installed with blocks, and the diameter of the block is larger than the diameter of the dividing rod.

Through this action, the distance between adjacent paper shells is intermittently increased, which makes it easier for the wax water to enter the position between adjacent paper shells, thereby improving the coloring uniformity of the paper shells.

[0018] By setting the rotating drum and the clamping member, in the process of the placement box driving the paper shell to rotate circumferentially, the paper shell moves due to gravity or buoyancy, and the movement is radial movement, so that the contact time between the paper shell and the inner wall of the placement box is shortened, thereby increasing the amount of wax water contacted by the paper shell close to the inner wall of the placement box, thereby improving the coloring uniformity of the paper shell.

[0019] Through the arrangement of the telescopic cylinder and the paddle, in the process of the rotating drum driving the placing box to rotate circumferentially, the telescopic cylinder drives the paddle to move axially in the rotating drum, so that the paddle drives the wax water in the rotating drum to flow axially. Through this action, in the process of the interval between the adjacent paper shells being intermittently increased, the axially flowing wax water can more easily enter the position between the adjacent paper shells, thereby improving the coloring uniformity of the paper shells.

[0020] Through the arrangement of the telescopic cylinder and the paddle, in the process of the wax water in the rotating drum being driven by the paddle to flow axially, the axially flowing wax water can easily drive the paper shell to move axially, so that the contact time between the paper shell and the inner wall of the placement box is shortened, thereby increasing the amount of wax water contacting the paper shell close to the inner wall of the placement box, thereby improving the coloring uniformity of the paper shell.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] Example 1: Please refer to Figure 1 and Figure 2A paper shell auxiliary coloring device comprises a left mounting seat 1, a right mounting seat 2 is arranged on the right side of the left mounting seat 1, the left mounting seat 1 and the right mounting seat 2 are both fixedly connected to the ground, a rotating drum 3 is sealed and rotatably mounted on the opposite sides of the left mounting seat 1 and the right mounting seat 2, gear teeth 4 are fixedly mounted on the outer side of the rotating drum 3 at equal intervals in the circumferential direction, a power mechanism (such as a combination of a motor and a gear in the prior art, not shown in the figure) is arranged on one side of the rotating drum 3, the power mechanism and the gear teeth 4 form a transmission connection, the inside of the rotating drum 3 and the inside of the right mounting seat 2 are jointly provided with a wax water cavity, and the wax water cavity An opening is provided on the side of the right mounting seat 2 facing away from the rotating drum 3, a placement box 5 is placed in the wax-water cavity and at a position corresponding to the rotating drum 3, the opening of the placement box 5 faces away from the left mounting seat 1, a box cover 6 is fixedly installed at the opening of the placement box 5, through holes are equidistantly provided on the wall of the placement box 5 and the interior of the box cover 6, so that the cavity of the placement box 5 is connected with the wax-water cavity through the through holes, a clamp 7 is fixedly installed on the inner wall of the wax-water cavity and at a position corresponding to the rotating drum 3, the clamp 7 forms a sliding clamping connection with the four edges of the circumferential side of the placement box 5, and paper shells (such as Figure 3 As shown), a closing plate 8 is sealed and fixedly installed at the opening of the wax water cavity, a fixing rod 9 is fixedly installed at the center position of the closing plate 8, one end of the fixing rod 9 facing the box cover 6 is rotatably connected with the center position of the box cover 6, and the end of the fixing rod 9 facing away from the box cover 6 is fixedly connected to a moving mechanism (the prior art, such as a mechanical arm, not shown in the figure), a connecting pipe 10 is fixedly installed at the lower position inside the left mounting seat 1, one end of the connecting pipe 10 is connected to the wax water cavity, and the other end of the connecting pipe 10 is connected to a wax water conveying mechanism (the prior art, such as a water pump, not shown in the figure), a through hole 11 is opened at the upper position inside the left mounting seat 1, the lower end of the through hole 11 is connected to the wax water cavity, and the upper end of the through hole 11 is connected to the external environment.

[0034] When in use, firstly, the moving mechanism is used to drive the fixing rod 9, the closing plate 8, the box cover 6 and the placement box 5 into the wax water chamber until the closing plate 8 seals the opening of the wax water chamber. At this time, the clamp 7 fixes the placement box 5. After that, the wax water conveying mechanism fills the wax water into the wax water chamber through the connecting pipe 10 until the wax water is higher than the placement box 5 (in this process, the wax water squeezes the excess air in the wax water chamber out of the through hole 11 to the external environment). Then, the power mechanism drives the rotating drum 3, the clamp 7, the placement box 5 and the box cover 6 to rotate slowly in the wax water. In this process, the stacked paper shells in the placement box 5 change their positions (for example, from the top layer to the bottom layer) as the placement box 5 rotates, and are moved in sequence under the action of buoyancy (because in the process of the paper shells exchanging their positions, the paper shells are in a state of rotation for a period of time). The transition from the vertical state to the horizontal state, and the friction resistance between the paper shell and the inner wall of the placement box 5 makes the buoyancy of the paper shell moving from the bottom to the top first overcome the above friction resistance, and then float upward). Through this action, the distance between adjacent paper shells is intermittently increased, which makes it easier for wax water to enter the position between adjacent paper shells, thereby improving the coloring uniformity of the paper shells. At the same time, since the paper shells in this device are always immersed in wax water, the coloring uniformity of the paper shells is further improved. In addition, in the process of the placement box 5 driving the paper shell to rotate circumferentially, the paper shell moves due to the buoyancy, and the movement is radial movement (relative to the rotating drum 3), which shortens the contact time between the paper shell and the inner wall of the placement box 5, thereby increasing the amount of wax water contacted by the paper shell close to the inner wall of the placement box 5, thereby improving the coloring uniformity of the paper shell.

[0035] See also Figure 1 and Figure 2 A telescopic cylinder 12 (such as a combination of a telescopic cylinder body and an output rod in the prior art) is fixedly installed at the central position inside the left mounting seat 1, and a paddle plate 13 is provided inside the wax water chamber and at a position on the side of the clamp 7 facing away from the closing plate 8. The output rod of the telescopic cylinder 12 extends into the wax water chamber and is fixedly connected with the paddle plate 13, and the diameter of the paddle plate 13 is smaller than the diameter of the wax water chamber.

[0036] In the process of the rotating drum 3 driving the placement box 5 to rotate circumferentially, the telescopic cylinder 12 drives the paddle 13 to move axially in the rotating drum 3, so that the paddle 13 drives the wax water in the wax water chamber to flow axially. Through this action, in the process of the intermittent increase of the spacing between the adjacent paper shells, the axially flowing wax water can more easily enter the position between the adjacent paper shells, thereby improving the coloring uniformity of the paper shells. In addition, the axially flowing wax water can easily drive the paper shells to move axially, thereby shortening the contact time between the paper shells and the inner wall of the placement box 5, thereby increasing the amount of wax water contacting the paper shells close to the inner wall of the placement box 5, thereby improving the coloring uniformity of the paper shells.

[0037] The height of the upper end of the through hole 11 is higher than the height of the uppermost position of the wax-water chamber.

[0038] When the output rod of the telescopic cylinder 12 enters the wax water chamber, the height of the wax water in the wax water chamber will increase. The through hole 11 is provided to prevent the wax water from overflowing and causing waste.

[0039] Example 2: Please refer to Figure 1-Figure 8 This embodiment is a further improvement of the first embodiment, and the improvement lies in that partition rods 14 are longitudinally equidistantly arranged in the cavity of the placement box 5 and near the position of the dial plate 13, the partition rods 14 are located between adjacent paper shells, and the spacing between adjacent partition rods 14 is greater than the thickness of the paper shell.

[0040] By setting the dividing rod 14, in the process of the above-mentioned placement box 5 driving the paper shell to rotate circumferentially, the paper shells that float up one by one will be blocked by the corresponding dividing rod 14, so that when all the paper shells float up to the limit position due to the buoyancy, there is still a distance between adjacent paper shells. Through this action, the coloring uniformity of the paper shell is improved. In addition, since the dividing rod 14 is set at a position close to the paddle 13, when the corresponding paper shell floats to the limit position and is blocked by the dividing rod 14, the paper shell will be deflected (the part of the paper shell away from the dividing rod 14 is tilted upward and exceeds the height of the dividing rod 14). Through this action, the wax water flowing axially in the wax water cavity can more easily exert force on the paper shell (the contact area is increased), which shortens the contact time between the paper shell and the fixed position of the inner wall of the placement box 5, and then increases the amount of wax water contacted by the paper shell close to the inner wall of the placement box 5, thereby improving the coloring uniformity of the paper shell.

[0041] See also Figure 1-Figure 8A fixed platform 15 is fixedly installed on the inner wall of the rotating drum 3 and located in the front and rear positions of the placement box 5. A No. 1 sliding cavity 16 is opened inside the fixed platform 15 and far away from the dial plate 13. A No. 1 sliding rod 17 is installed in the inner cavity of the No. 1 sliding cavity 16 in a sealing and sliding manner. The No. 1 sliding rod 17 extends out of the No. 1 sliding cavity 16 toward one end of the placement box 5. A pressing plate 18 is fixedly installed on the end of the No. 1 sliding rod 17 toward one end of the placement box 5. A spring 19 is provided in the inner cavity of the No. 1 sliding cavity 16. One end of the spring 19 is fixedly connected to the end of the No. 1 sliding rod 17 facing away from the placement box 5. The other end of the spring 19 is fixedly connected to the inner wall of the No. 1 sliding cavity 16. A No. 2 sliding cavity 20 is opened inside the fixed platform 15 and close to the dial plate 13. A No. 2 sliding cavity 20 is sealed and slidably installed with a No. 2 sliding rod 21. The No. 2 sliding rod 21 extends toward A No. 2 slide cavity 20 extends out to one end of the paddle plate 13, and the No. 2 slide bar 21 is axially overlapped with the paddle plate 13. A liquid guide hole 22 is provided inside the fixed platform 15, and one end of the liquid guide hole 22 is communicated with a cavity in the No. 1 slide cavity 16 located at the No. 1 slide bar 17 facing away from the placement box 5, and the other end of the liquid guide hole 22 is communicated with a cavity in the No. 2 slide cavity 20 located at the No. 2 slide bar 21 facing away from the paddle plate 13. The cavity in which the No. 1 slide cavity 16, the liquid guide hole 22 and the No. 2 slide cavity 20 are connected is filled with hydraulic oil, and the partition rod 14 is an elastic rod, and both ends of the partition rod 14 extend out of the placement box 5, and the part of the partition rod 14 extending out of the placement box 5 forms a sliding connection with the placement box 5, and blocks 23 are fixedly installed at both ends of the partition rod 14 and located in the cavity of the placement box 5, and the diameter of the block 23 is larger than the diameter of the partition rod 14.

[0042] In the process of the placement box 5 driving the paper shell to rotate circumferentially, as the output rod of the telescopic cylinder 12 extends, the paddle plate 13 contacts and pushes the second slide bar 21, so that the second slide bar 21 gradually squeezes the hydraulic oil in the second slide cavity 20 into the first slide cavity 16 through the liquid guide hole 22, and the hydraulic oil entering the first slide cavity 16 drives the first slide bar 17 to gradually extend out of the first slide cavity 16 and stretch the spring 19, and the gradually extended first slide bar 17 drives the corresponding pressing plate 18 to squeeze the partition rod 14 out of one end of the placement box 5. Since the pressing plate 18 is set at the partition On both sides of the rod 14, when both sides of the dividing rod 14 are squeezed, the dividing rod 14 in the placement box 5 will bend and deform, thereby driving the contacted paper shell to move. Afterwards, when the paddle 13 is reset, the spring 19 drives the No. 1 slide bar 17 to reset, so that the No. 2 slide bar 21 and the dividing rod 14 are reset synchronously. The reset dividing rod 14 will also drive the contacted paper shell to move. Through the above action, the wax water is easier to enter the position between adjacent paper shells, while reducing the contact time between the fixed position of the paper shell and the dividing rod 14, so that the coloring uniformity of the paper shell is improved.
