Description

Technical Field

[0001] The invention relates to packaging box making equipment, in particular to a device for breaking the glue-coated surface of a medicine packaging box. Background Art

[0002] Currently, most commonly used medicine packaging boxes are made of paper, which is formed by bending the paper and coating it with glue.

[0003] However, as the paper material of the medicine packaging box, it is necessary to coat the surface of the paper to ensure that the medicine packaging box has strong waterproof properties. However, after the medicine packaging box is coated with film and adhesive, the adhesive is coated on the surface of the film, and the adhesion between the adhesive and the film is low. After the side of the packaging box is bent, it is directly glued, and the adhesion effect is poor. It is easy to fall off, affecting the packaging effect. Summary of the invention

[0004] The present invention provides a device for breaking the glue-coated surface of a medicine packaging box. Before gluing, the packaging box paper passes through the device, and the device breaks the gluing position of the packaging box paper, mainly breaking the film layer on the surface of the packaging box paper, so that after gluing, the adhesive can penetrate under the film layer and contact the paper body, so that the packaging box paper body can be bonded together during bonding after gluing, and the bonding effect is good and it is not easy to fall off.

[0005] The specific technical solution of the present invention is: a device for breaking the glue-coated surface of a pharmaceutical packaging box, comprising a workbench, a pressing wheel and a breaking wheel arranged above and below the workbench, the rotation axes of the pressing wheel and the breaking wheel are parallel, breaking teeth are arranged on the outer periphery of the breaking wheel, a circle of grooves is arranged in the middle position of the outer periphery of the pressing wheel, the breaking wheel is opposite to the groove, and the breaking teeth of the breaking wheel extend into the groove.

[0006] The pressing wheel and the surface breaking wheel are arranged opposite to each other up and down, and the workbench is between the pressing wheel and the surface breaking wheel. The packaging box paper is placed on the workbench, and the workbench is used to support the paper. The paper moves forward on the workbench, and passes through the gap between the pressing wheel and the surface breaking wheel during the movement. The pressing wheel and the surface breaking wheel rotate relatively, and the coated surface of the paper to be broken faces the surface breaking wheel. As the paper moves forward, the surface breaking teeth of the surface breaking wheel cut a slit on the coated surface of the paper, and the slit causes the coating layer on the surface of the paper to be cut. In the subsequent gluing process, the glue can penetrate under the coating layer and soak into the paper body, so that the packaging box paper body can be bonded together during gluing, with good bonding effect and not easy to come off; the rotation speed of the surface breaking wheel is generally equal to the moving speed of the paper, so that intermittent slits are formed on the coated surface of the paper, or the surface breaking wheel The rotation speed is greater than the moving speed of the paper, so that a continuous crack is formed on the coated surface of the paper; a circle of grooves is set in the middle position of the outer peripheral surface of the pressure wheel, the surface breaking wheel is opposite to the groove, and the surface breaking teeth of the surface breaking wheel extend into the groove. When the outer peripheral surface of the pressure wheel contacts the surface of the paper, due to the top effect of the surface breaking wheel, the paper forms a bend in the groove. The bend is generally arc-shaped. The arc-shaped bend makes the coated surface of the paper only contact the two sides of the surface breaking wheel, that is to say, the middle part of the tooth top of the surface breaking teeth of the surface breaking wheel does not contact the coated surface of the paper. In this way, the position where the paper is broken will not cause the coating layer to be completely cut off, ensuring that the coating layer between the cracks and the entire coating layer of the paper are still an integrated structure. When bonding, it is equivalent to forming a membrane skeleton at the bonding position, and the bonding effect is better.

[0007] Further preferably, a notch is provided on the workbench, the pressing wheel is located above the workbench, the surface breaking wheel is located below the workbench, the periphery of the surface breaking wheel corresponds exactly to the position of the notch, and the surface breaking teeth extend from the notch to the workbench. The paper piece moves forward on the workbench, the pressing wheel presses the paper piece, and the surface breaking wheel breaks the film-coated surface of the paper piece, that is, the surface breaking wheel and the pressing wheel are located exactly above and below the workbench. In order to facilitate the pressing wheel to press the paper piece, the pressing wheel is arranged above the workbench, and the surface breaking wheel is arranged below the workbench, so a notch is provided on the workbench for the surface breaking teeth of the surface breaking wheel to extend out.

[0008] Further preferably, the width of the groove is greater than the thickness of the surface breaking wheel, the surface breaking teeth extend into the groove to a depth less than the depth of the groove, and a gap is left between the tooth top of the surface breaking teeth and the bottom of the groove. The depth of the surface breaking teeth extending into the groove is less than the depth of the groove, and this depth is greater than the thickness of the paper, so that when the pressing wheel presses the paper, the paper is pushed into the groove by the surface breaking wheel, and the paper will bend in an arc shape in the groove, and only the two ends of the surface breaking teeth are involved in the surface breaking, so as to prevent the coating layer of the paper from being completely cut off.

[0009] Further preferably, the main body of the pressing wheel is made of metal, and two rubber rings are fixed on the outer periphery of the pressing wheel, the two rubber rings are located on both sides of the main body, and the area between the two rubber rings forms the groove of the pressing wheel. A convex ring is arranged on the outer periphery of the metal main body of the pressing wheel, and two rubber rings are fixed on both sides of the outer periphery of the pressing wheel, the two rubber rings are located on both sides of the convex ring, and the area between the two rubber rings forms the groove of the pressing wheel. The two sides of the convex ring can position the rubber rings. When the pressing wheel is working, the outer periphery of the rubber rings contacts the surface of the paper, and the rubber rings can provide greater friction and have appropriate elasticity to avoid indentations on the surface of the paper.

[0010] Further preferably, a bracket is provided on the side of the workbench, a screw lifting mechanism is provided above the bracket, a transverse connecting shaft is provided on the screw lifting mechanism, and the pressure wheel is connected to the transverse connecting shaft. The transverse connecting shaft can be lifted and lowered relative to the workbench under the action of the screw lifting mechanism, and the pressure wheel is lifted and lowered synchronously with the transverse connecting shaft, that is, the gap between the pressure wheel and the workbench surface is adjustable, so as to meet the paper thickness requirements of different packaging boxes.

[0011] Further preferably, a driving motor is arranged below the bracket, and the surface breaking wheel is connected and fixed to the output shaft of the driving motor.

[0012] Further preferably, the cross-sectional shape of the broken face tooth is an oblique triangle, including a front tooth surface and a rear tooth surface, and the front tooth surface passes through the wheel center of the broken face wheel.

[0013] Further preferably, the front tooth surface of the face-breaking tooth is located at the front side of the rotation direction of the face-breaking wheel when it is working.

[0014] Further preferably, the middle part of the tooth top of the face breaking tooth is concave to form a face edge, and the two end parts of the tooth top form face breaking blades, and the two end points of the tooth top are the blade tips of the face breaking blades. The face edge refers to a surface structure without blades, that is, the middle part of the tooth top of the face breaking tooth does not participate in the face breaking, and only the face breaking blades are formed at the two ends of the tooth top, so that when breaking the surface, there is no need to consider that the middle part of the tooth top will completely cut off the coating layer of the paper.

[0015] It is further preferred that there is an inclined rear blade surface between the surface breaking blade and the rear tooth surface. The angle between the rear blade surface and the front tooth surface is controlled at 30-45 degrees. After the surface breaking, as the surface breaking teeth rotate and the paper moves, the rear blade surface produces an indentation on the paper body, and the indentation creates a gap between the surface of the paper body and the inner surface of the coating layer, which is convenient for the adhesive to penetrate, and also convenient for the surface breaking blade to separate from the paper body.

[0016] The beneficial effect of the present invention is that the surface breaking teeth of the surface breaking wheel cut a slit on the coated surface of the paper piece, and the coating layer on the surface of the paper piece is cut by the slit. In the subsequent gluing process, the adhesive can penetrate under the coating layer and soak into the paper body, so that the paper body of the packaging box can be bonded together during gluing, and the bonding effect is good and it is not easy to fall off.

DETAILED DESCRIPTION

[0023] The present invention will be further described below through specific embodiments in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] like Figure 1 Figure 2 Figure 3 As shown, a device for breaking the glued surface of a medicine packaging box comprises a workbench 3 supported by legs 6, a pressing wheel 1 and a breaking wheel 4 arranged above and below the workbench, the pressing wheel is above the workbench, the breaking wheel is below the workbench, the rotation axes of the pressing wheel and the breaking wheel are parallel, a notch 2 is arranged on the workbench, and the periphery of the breaking wheel just corresponds to the position of the notch. Breaking teeth 5 are arranged on the periphery of the breaking wheel, and the breaking teeth extend from the notch to the workbench.

[0026] The main body of the pressing wheel is made of metal, and a convex ring is arranged on the outer periphery of the metal main body. Two rubber rings are fixed on the outer periphery of the pressing wheel, and the two rubber rings are located on both sides of the convex ring. A groove 8 on the outer periphery of the pressing wheel is formed between the two rubber rings. The face breaking wheel faces the groove, and the face breaking teeth of the face breaking wheel extend into the groove. The width of the groove is greater than the thickness of the face breaking wheel, and the face breaking teeth extend into the groove to a depth less than the depth of the groove, and a gap is left between the tooth top of the face breaking teeth and the bottom of the groove.

[0027] A bracket is provided on the side of the workbench, a screw lifting mechanism is provided above the bracket, a transverse connecting shaft is provided on the screw lifting mechanism, and a pressure wheel is connected to the transverse connecting shaft. The screw lifting mechanism drives the transverse connecting shaft to rise and fall, and the transverse connecting shaft drives the pressure wheel to rise and fall, thereby adjusting the gap between the outer periphery and the upper surface of the workbench to adapt to the thickness of different paper pieces.

[0028] A driving motor is arranged under the bracket, and the face-breaking wheel is connected and fixed to the output shaft of the driving motor. The output shaft of the driving motor is parallel to the horizontal connecting shaft and is perpendicular to the side of the workbench, that is, the pressing wheel and the face-breaking wheel are parallel to the side of the workbench.

[0029] The cross-sectional shape of the face-breaking tooth is an oblique triangle, including a front tooth surface 14 and a rear tooth surface 13. The front tooth surface passes through the wheel center of the face-breaking wheel, and the front tooth surface of the face-breaking tooth is at the front side of the rotation direction of the face-breaking wheel when working.

[0030] The rotation speed of the pressing wheel is equal to the speed at which the paper 7 moves forward, and the rotation speed of the surface breaking wheel is equal to the speed at which the paper moves forward. When the outer peripheral surface of the pressing wheel contacts the surface of the paper, due to the pushing action of the surface breaking wheel, the paper forms a bend in the groove. The bend is generally in an arc shape. The arc bend makes the coated surface of the paper only contact the two sides of the surface breaking wheel, and the surface breaking teeth break the coated surface of the paper to form intermittent seams.

[0031] Embodiment 2:

[0032] like Figure 4 Figure 5 As shown, a device for breaking the glue-coated surface of a medicine packaging box is different from Example 1 in that:

[0033] The middle part of the tooth top of the face-breaking tooth is concave to form a face edge 10, and the two ends of the tooth top form inclined face-breaking blades 9, which are inclined and extend from both sides of the face edge to the end points of the face-breaking tooth. The two ends of the tooth top are the blade tips 11 of the face-breaking blades. Between the face-breaking blade and the rear tooth surface is an inclined rear blade surface 12, and the angle of the rear blade surface relative to the front tooth surface is controlled at 35°. The rest of the structure refers to Example 1.

[0034] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
