For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0026] like Figure 1-Figure 5 As shown, an automatic waste discharge device for sheet-type self-adhesive label production includes a conveyor line 1 and a feeding mechanism, a tape pressing mechanism, and a waste stripping mechanism sequentially arranged on the conveyor line 1 along the conveying direction;

[0027] Among them, the conveyor line 1 includes a belt 2 provided with a plurality of ventilation holes 201, and a vacuum suction plate 3 attached to the inner side of the belt 2. The vacuum suction plate 3 is externally connected to a negative pressure air source. When the vacuum suction plate 3 is connected to the negative pressure air source, it can apply a force to the conveyed label backing paper through the ventilation holes 201 on the belt 2 to adsorb the label backing paper on the upper surface of the belt 2, so as to prevent the label backing paper from deviating in position during the conveying process. Moreover, by being supported on the inner side of the belt 2 by the vacuum suction plate 3, the upper surface of the belt 2 can also be made more stable during operation;

[0028] The feeding mechanism includes a limit baffle 4 and a limit side plate 5 erected above the belt 2. The limit baffle 4 and the limit side plate 5 enclose a U-shaped feeding station. The sheet-type labels can be stacked on the belt 2, and the position of the labels is restricted and regularized through the U-shaped feeding station; at the same time, a gap is reserved between the bottom side of the limit baffle 4 and the upper surface of the belt 2, and the height of this gap only allows a single label to pass through. The label at the bottom layer will be subjected to the downward pressure of the upper labels and the suction force applied by the vacuum suction plate 3 through the ventilation holes 201 at this time, and can be flatly laid on the upper surface of the belt 2. When the belt 2 moves along the conveying direction, the label at the bottom layer will move synchronously with the belt 2 until the label at the bottom layer completely passes through the gap between the limit baffle 4 and the upper surface of the belt 2, and then the upper labels can be successively and completely flatly laid on the upper surface of the belt 2 and successively pass through the gap between the limit baffle 4 and the upper surface of the belt 2, so that the stacked labels can be conveyed along the conveying direction in a head-to-tail connection manner;

[0029] The tape pressing mechanism includes a tape unwinding roller 6 suspended above the belt 2 and a set of pressing roller assemblies that can press down on the upper surface of the belt 2. A roll of tape can be placed on the tape unwinding roller 6, and the tape unwinding roller 6 is a damping roller commonly used in the prior art, which generates appropriate frictional force and viscous force when rotating. One end of the roll of tape can be adhered to the edge part of the label after passing around the pressing roller assembly, that is, the waste part of the tape adhered to the label, so as to promote that a plurality of successively flatly laid sheet-type labels conveyed on the belt 2 can be connected together by the tape;

[0030] The waste stripping mechanism includes a waste winding roller 7 suspended above the belt 2, a group of strip-shaped stripping blades 8 inclined toward the upper surface of the belt 2, and a group of wheel brushes 9 that can be pressed down on the upper surface of the belt 2. The conveyor line 1 is provided with a servo drive 10 that can drive the wheel brush 9 to rotate; the waste winding roller 7 can be driven by a servo motor and other equipment to wind up the waste on several sheet labels adhered together by tape. Among them, the waste part on the sheet label is wound around the strip peeling knife plate 8 and then wound on the waste winding roller 7. When the waste winding roller 7 is winding, the vacuum suction plate 3 exerts a certain adsorption force on the sheet label base paper, which can cause the label base paper to be firmly attached to the belt 2, and the servo drive 10 can drive the wheel brush 9 to rotate. The servo drive 10 can select the servo motor, stepper motor, etc. commonly used in the prior art; when the wheel brush 9 rotates, it can apply a downward pressure on the label in the same direction as the adsorption force, which can further cause the label base paper to be attached to the belt 2; in this technical solution, the conveying direction of the conveyor line 1 and the rotation direction of the wheel brush 9 are as follows Figure 4 As shown, if the label backing paper follows the waste material and tilts up, the brush on the wheel brush 9 applies a vertical downward force to the label backing paper, which can separate the label backing paper from the waste material and make the label backing paper lay flat on the belt 2 again. In this technical solution, the waste material on the label will be separated from the label backing paper under the traction of the waste material winding roller 7, thereby obtaining a finished label.

[0031] As mentioned above, the conveyor line 1 is a belt conveyor commonly used in the prior art. The label is composed of a label base paper and a label face paper. The label face paper on the label base paper will be cut out of the label. The part of the label face paper without the label is all waste. The label base paper after the waste is removed and the label cut out on the label base paper form a finished label. This technical solution is mainly through laying a number of labels one by one on the belt 2, and the belt 2 is used to convey them. During the conveying process, vacuum adsorption is used to ensure that the labels can be laid flat on the belt 2, and can also move synchronously with the belt 2. Then, the waste parts on several labels are connected by tape, and then the label base paper and the waste are separated by a strip peeling knife plate 8 and a wheel brush 9, so that only the label remains on the label base paper, and then the waste connected together is collected by the waste winding roller 7. The automatic waste discharge device for sheet-type self-adhesive label production in this technical solution can efficiently complete the operation of removing waste from sheet-type labels.

[0032] The above, such as Figure 1 As shown, a guide light shaft 12 is arranged above the conveyor line 1 through a trunnion foot 11, and a plurality of slide seats 13 are slidably connected to the guide light shaft 12. The slide seats 13 are threadedly connected with fixing bolts that can abut against the outer periphery of the guide light shaft 12. By tightening the fixing bolts, the slide seats 13 can be fixed at any position on the guide light shaft 12;

[0033] There are two limit side plates 5, and the two limit side plates 5 are symmetrically arranged along the limit baffle 4. The limit baffle 4 and the limit side plates 5 are both detachable and connected to the slide 13. The two limit side plates 5 and the limit baffle 4 are arranged to form a U-shaped structure, which can limit the position of the stacked labels from multiple ranges. At the same time, in this technical solution, the position of the slide 13 on the guide light axis 12 can also be adjusted according to the size of the label backing paper, thereby increasing the diversity and applicability of the device.

[0034] The above, such as Figure 1 As shown, a material blocking baffle 14 which can be abutted against the upper surface of the belt 2 is provided on the limiting side plate 5, and one end of the material blocking baffle 14 can extend in the direction away from the tape pressing mechanism, and its length is greater than the length of a single label backing paper, and one side of the material blocking baffle 14 which limits the edge of the label backing paper is flush with the side of the label backing paper on the limiting side plate 5 to prevent the bottom layer of the label backing paper from getting stuck.

[0035] Furthermore, the pressure roller assembly includes a set of vertical adjustable bearing seats 15, a first roller 16 and a second roller 17 are arranged between the set of vertical adjustable bearing seats, a set of rubber rollers 18 are sleeved on the outer periphery of the first roller 16, and the rubber rollers 18 can press down on the upper surface of the belt 2. The vertical adjustable bearing seat 15 is a non-standard accessory commonly used in the prior art, which can be used to adjust the horizontal height of the first roller 16 and the distance between the rubber roller 18 and the upper surface of the belt 2, ensure the pressure of the rubber roller 18 pressing down on the tape and the label waste, and ensure that the adhesion between the tape and the waste is tighter.

[0036] In this embodiment, the brush on the wheel brush 9 is a hard brush to increase the force between the wheel brush 9 and the label backing paper, and prevent the wheel brush 9 from being unable to peel the waste material from the label backing paper due to the easy deformation of the brush.

[0037] Furthermore, the height of the gap reserved between the bottom side of the limiting baffle 4 and the upper surface of the belt 2 is greater than the thickness of a single label and less than the thickness of two labels.

[0038] Furthermore, the height of the gap reserved between the bottom side of the limiting baffle 4 and the upper surface of the belt 2 is greater than the thickness of a single label and less than the thickness of two labels.

[0039] Furthermore, there are two rubber rollers 18 , and two rolls of adhesive tape can be placed on the tape unwinding roller 6 at one time, and the two rubber rollers 18 are symmetrically arranged along the limiting baffle 4 .

[0040] Working principle: The Zhang-style labels can be stacked on the belt 2. The U-shaped feeding station restricts and regularizes the positions of the labels. The gap reserved between the bottom side of the limit baffle 4 and the upper surface of the belt 2 only allows a single label to pass through. At the same time, the vacuum suction plate 3 is externally connected to a negative pressure air source. When the vacuum suction plate 3 is connected to the negative pressure air source, when transporting the labels through the belt 2, it can also apply a force to the backing paper of the transported labels through the ventilation holes 201 on the belt 2 to adsorb the backing paper of the labels on the upper surface of the belt 2, so as to promote the stacked labels to be transported one by one by the belt 2. Subsequently, during the process of the belt 2 transporting the labels, one end of the roll-type tape successively bypasses the rubber roller 18 on the second roller 17 and the first roller 16, so that the tape adheres to the waste part on the label, thereby promoting a plurality of Zhang-style labels transported on the belt 2 and laid flat in sequence to be connected together by the tape. Then, the waste winding roller 7 winds up the tape and the waste part on the label face paper, separating the waste part from the label part, thus realizing an efficient waste discharging operation. During this process, since the vacuum suction plate 3 exerts a certain adsorption force on the backing paper of the Zhang-style label, it can promote the backing paper of the label to firmly adhere to the belt 2, and the servo drive 10 can drive the wheel brush 9 to rotate. When the wheel brush 9 rotates, it can apply a downward pressure to the label in the same direction as the adsorption force, so as to promote the backing paper of the label to closely adhere to the belt 2. At the same time, the bristles on the wheel brush 9 can also apply a vertically downward force to the backing paper of the label, and this force can promote the separation of the backing paper of the label from the waste.

[0041] Based on the ideal embodiments of the present invention as inspiration, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
