[0031] See attached Figures 1-17 , reflecting a specific structure of the present invention, the label removal device of the barrel cover of bottled water can realize the assembly line processing of the barrel covers 100 in batches.

[0032] The principle of cutting positioning of the device is as follows Figure 1 、 2 As shown: the bottom end surface 133 of the barrel cover 100 is transported to the positioning plate 102, and the opening and closing positioning fixture 104 clamps and positions the barrel cover 100 from both sides of the barrel cover 100 so that it is located in the through hole 103; when the lifting and pressing column 105 descends, it is inserted into the inner cavity of the barrel cover 100 and pressed on the top of the bottom end surface 133 of the barrel cover 100, and the tool head of the rising rotating tool 101 passes through the through hole 103 and abuts against the bottom of the bottom end surface 133 to cut the remaining label.

[0033] During the above process, the barrel cover 100 is circumferentially positioned using an open and close positioning fixture 104 to ensure that each barrel cover 100 is concentric with the through hole 103 and its rotating tool 101, thereby ensuring stable barrel cover processing and improving processing accuracy; the barrel cover 100 has a shape with an inner cavity open at one end, and with the cooperation of the through hole 103 of the positioning plate 102, the lifting and pressure column 105 is inserted into the inner cavity of the barrel cover 100 when it descends and presses on the top of the bottom end surface 133 for high and low positioning, and then the rotating tool 101 cuts off the residual label adhered to the bottom end surface.

[0034] Since the bottom end face 133 is thin (about 0.8-1.0 mm) by itself, and the residual label adhered below the bottom end face is even thinner (about 0.05-0.08 mm), the positioning accuracy in the height direction is extremely high and the processing is difficult. The above technical solution effectively solves the technical problem, ensures that the horizontal height of the to-be-processed plane of all the barrel covers is consistent, and the positioning accuracy can reach within 0.02 mm; at the same time, this high-low positioning mode is not affected by the deformation and defects of the barrel cover, and the equipment will not appear the phenomenon of jamming; therefore, the automatic removal of the residual label on the barrel cover can be completed, and the tedious and repetitive label removal work of manual operation is eliminated.

[0035] In the example, the label removal device of the barrel cover of the bottled water includes a rotating cutter 101 arranged correspondingly, a through hole 103 arranged on a positioning plate 102, an open-close positioning clamp 104, and a lifting pressure column 105. Four lifting pressure columns 105 are connected by a connecting piece and driven to lift by a pressure column cylinder 106, four through holes 103 are arranged in combination on a positioning plate 102, and two side clamping bodies of four pairs of open-close positioning clamps 104 are connected in combination and driven to translate by a clamp cylinder 108.

[0036] The four through holes 103 are arranged side by side on the positioning plate 102, a cover plate 110 driven to translate by a cover plate cylinder 109 is arranged on the positioning plate 102, the cover plate 110 is closed to the four through holes 103 when it is translated to a working position, guardrails 111 are arranged on the upper two sides of each through hole 103, the two side guardrails 111 form a barrel cover channel, and the barrel cover 100 is conveyed by a conveying belt 114 into the barrel cover channel on the cover plate 110; the two ends of the barrel cover channel are provided with openable feeding stop rods 112 and discharging stop rods 113. The discharging stop rods 113 are controlled to open and close by a discharging stop rod cylinder 131, and the feeding stop rods 112 are controlled to open and close by a feeding stop rod cylinder 132.

[0037] When the translating cover plate 110 is closed, it is closed to the four through holes 103, so that the barrel cover 100 is stable and smooth when it enters and passes through the barrel cover channel, and the barrel cover 100 will not be knocked, jammed or stopped due to the through holes 103; the high-speed rotating cutter in the through hole 103 is hidden in the machine body through the translating cover plate 110, thereby improving the safety factor and eliminating safety hazards;

[0038] When the conveying belt 114 is conveyed into the barrel cover channel, the discharging stop rods 113 close the discharging end of the barrel cover channel; after four barrel covers 100 are input, the feeding stop rods 112 close the feeding end of the barrel cover channel, so as to facilitate the open-close positioning clamp 104 to act and close, and each barrel cover 100 is clamped and positioned on the corresponding through hole 103;

[0039] The lifting pressure column 105 is lowered to position the barrel cover 100 in height, and the rotating cutter 101 is used to cut the label.

[0040] The bucket cover passage formed by the guardrails 111 can guide the bucket cover 100 to move forward without deviation; in the example, the opening and closing positioning clamp 104 is provided with a groove 115 corresponding to the guardrail 111, and the guardrail 111 is embedded in the groove 115 when the opening and closing positioning clamp 104 is closed. The structure of the guardrail and the clamp can be effectively simplified, and the movement interference between the guardrail and the opening and closing positioning clamp can be avoided; when the opening and closing positioning clamp 104 releases the bucket cover 100, the guardrail 111 prevents the bucket cover 100 from being clamped on the clamp in the row position, thereby affecting the next process of the bucket cover 100 and causing the equipment to be unable to normally operate.

[0041] In the example, the lifting column 105 is provided with a gas passage 116, the gas passage 116 is connected to a pressure gas source (not shown in the figure) through a gas valve, and the gas passage 116 is provided with a gas jet port 117. After the rotary cutter 101 finishes cutting the label, the gas valve is opened, the gas jet port 117 blows air to drive the bucket cover 100, so that the bucket cover 100 is discharged from the discharge end of the bucket cover passage. The mechanism is simplified, and the work is reliable. In the example, the blind hole 118 is designed in cooperation with the shape of the bucket cover 100 with the intermediate protrusion, and the shape of the bucket cover can be changed correspondingly in the processing of other shapes.

[0042] In the example, the rotary cutter 101 is provided with a lifting mechanism. Four rotary cutters 101 are connected by a connecting piece and are driven to lift by a cutter cylinder 107, so that the label residues attached to the bottom of the bucket cover are cut layer by layer in the lifting process; at the same time, the cutter lifting can make the cutter head hidden in the through hole, and the automatic opening and closing of the cover plate can make the equipment body table clean, dust-free and ash-free during use.

[0043] In the example, the cutter head part of the rotary cutter 101 is arranged in the cutting bin 119, the upper surface of the cutting bin 119 is the positioning plate 102 provided with the through hole 103, and the lower surface of the cutting bin 119 is provided with the through hole 134 of the rotary cutter 101. The cutting bin 119 is provided with a negative pressure material suction mechanism: in the example, the side hole 120 of the cutting bin 119 is connected to a negative pressure generating mechanism (not shown in the figure) through the air pipe 121, so as to suck the material slag generated in the cutting of the label by the cutter.

[0044] In the example, the conveying belt 114 is provided with a color selection screening mechanism. Through automatic color selection screening, the device can completely replace manual selection of the bucket cover 100, so that the bucket cover is classified and processed according to color, different colored bucket covers are not mixed, thereby ensuring the stability of the next bucket cover processing; and improving the color purity of the re-injection product. In the example, the color selection screening mechanism includes four push heads 122 arranged on the side of the conveying belt 114, each push head 122 moves linearly to and from the bucket cover 100 on the conveying belt 114 under the drive of a color selection cylinder 123, and the color selection cylinder 123 is signal connected with a color sensor 124; the color sensor 124 can be purchased in the market, and is also called a color recognition sensor or a color sensor.

[0045] Color selection cylinder 123 receives the signal from color sensor 124 and drives push head 122 to push the corresponding bucket cover 100 to the movable window 125 on the wall of conveying belt 114, and into the collection channel 126. In the example, the end of the push head 122 has an arc-shaped end head 127 corresponding to the shape of the bucket cover 100. The arc-shaped end head 127 can be automatically positioned when pushing the bucket cover 100 and will not be offset.

[0046] In the example, the feeding end of the conveying belt 114 is connected to a cover arranger 128. The cover arranger 128, also known as a centrifugal cover arranger or rotary cover arranger, arranges the disordered bucket covers 100 into a posture with the bottom end facing upwards and sequentially transports them to the conveying belt 114. The cover arranger uses a rotating disc driven by a motor to rotate (clockwise or counterclockwise), generating centrifugal force to force the bucket covers 100 to be thrown into the edge groove of the rotating disc, and then arranged in sequence along the circular edge. The cover tail 129 at the upper end of the bucket cover 100 is used to screen out the bucket covers 100 with the upper end facing upwards, and the screened out bucket covers 100 fall into the rotating disc for recycling. The remaining bucket covers 100 are finally introduced into the conveying belt 114 from the gap of the rotating disc. The device is also provided with a control display screen 130.
