Description

Technical Field

[0001] The utility model relates to the field of paper bag machines, in particular to a continuous roll point-breaking type paper bag machine. Background Art

[0002] When packaging items, two packaging methods are generally used: plastic bags or paper bags. Paper is a recyclable resource. The raw material for papermaking is mainly plant fiber, which is biodegradable and recyclable.

[0003] 1. Paper bags on the market are usually single paper bags, which need to be collected during production, with many processes and high manufacturing costs; 2. Paper bags are easily damaged during transportation and are difficult to store. Summary of the invention

[0004] The utility model aims at the shortcomings of the prior art and provides a paper box bubble pressing mechanism which reduces production cost and is convenient for storage.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions: a continuous roll point-breaking type paper bag machine, comprising an unwinding mechanism, a bottom edge gluing mechanism, a side edge gluing mechanism, a paper bag tube forming mechanism, a bottom glue heat sealing mechanism and a winding mechanism which are arranged in sequence, the bottom edge gluing mechanism comprising a bottom glue drying part, the bottom edge gluing component is arranged in front of the side edge gluing component, a point-breaking mechanism is arranged in front of or behind the paper bag tube forming mechanism, and the point-breaking mechanism forms horizontally equidistant point-breaking lines on the roll material.

[0006] The utility model unwinds the paper roll, glues and dries the bottom edge, glues the side edge, forms the paper into a roll, and heat-seals the bottom glue before rewinding. Before or after the paper is formed into a roll, the point-breaking knife roller cuts the material to meet the process requirements and reduce production costs. The point-breaking line facilitates the separation of subsequent paper bags, and the rewinding mechanism rewinds multiple paper bags for easy storage.

[0007] The point breaking mechanism includes a point breaking knife roller and a driving roller rotatably arranged on a frame, a point breaking tool is installed on the point breaking guide roller, and a gap is provided between the driving roller and the point breaking knife roller for the coil to pass through. During point breaking, the point breaking tool is pressed against the driving roller. The point breaking knife roller drives the point breaking tool to press the coil to cut the dotted line when passing through the gap, and the coil is continuously transmitted to improve efficiency.

[0008] The point breaking tool is consistent with the axis direction of the point breaking knife roller along the length direction. The point breaking tool is arranged horizontally to meet the process requirements.

[0009] The driving roller is a rubber roller. The point breaking knife and the driving roller are pressed together to cut the dotted line of the coil, and the rubber roller avoids damaging the point breaking knife.

[0010] The bottom edge gluing mechanism includes a bottom edge gluing member, and the side edge gluing mechanism includes a side edge gluing member. The bottom edge gluing member, the bottom glue drying member, and the side edge gluing member are sequentially arranged along the roll material conveying path. The bottom edge gluing member firstly glues the material horizontally, and then dries it, and then the side edge gluing member glues the material vertically. Drying the bottom edge first can prevent the bottom edge glue from contaminating other parts when the paper is folded into a roll.

[0011] The point breaking mechanism is arranged between the side gluing mechanism and the bottom gluing mechanism. The point breaking is performed after the bottom glue is dried to prevent the glue from contaminating the point breaking tool.

[0012] The bottom glue gluing member is a bottom glue gluing roller, which is rotatably arranged on the frame, has a gluing convex strip, is transmission-connected to the bottom glue driving member, and the side gluing member is fixedly arranged on the left side of the frame. The bottom glue gluing roller is provided with a gluing convex strip, and the gluing is continuously applied to improve production efficiency.

[0013] The point-breaking mechanism is arranged behind the heat-sealing mechanism and performs point-breaking cutting on the formed paper bag, thereby reducing the length of the point-breaking tool, reducing the cost and facilitating the operation.

[0014] The point breaking knife roller and the driving roller are arranged opposite to each other up and down, which makes the layout more reasonable.

[0015] The point breaking component comprises a point breaking blade plate and a support plate which move up and down, and the coil passes between the point breaking blade plate and the support plate. The lifting point breaking blade plate performs point breaking on the coil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The utility model is further described in detail below with reference to the accompanying drawings and embodiments. Figure 1 The direction of the arrow on the left is the longitudinal direction, and the direction perpendicular to the paper feed direction is the transverse direction.

[0023] The point breaking mechanism 7 of the roll-type paper bag machine includes an unwinding mechanism 1, a bottom edge gluing mechanism, a side edge gluing mechanism, a paper bag tube forming mechanism 4, a bottom glue heat sealing mechanism 5 and a rewinding mechanism 6, wherein the unwinding mechanism 1 includes an unwinding frame, on which the rolled paper 10 is placed, and the bottom edge gluing mechanism includes a bottom glue drying member 21, which can be a hot air blower, a drying lamp, etc. The bottom edge gluing member is arranged in front of the side edge gluing member, that is, the roll material is firstly glued at the bottom (the glue strip is horizontal) and dried, and then the side edge (the glue strip is vertical) is glued, and then the paper 10 tube forming mechanism folds the paper 10, and the side glue on one side of the paper 10 is bonded to the other side of the paper 10 to make the paper 10 into a tube. The rolled paper 10 enters the bottom glue heat sealing mechanism 5 to dissolve the bottom glue, and the bottom edge of the rolled paper 10 is heat-sealed to complete the continuous roll paper bag 11, and the heat sealing mechanism can be a heat sealing roller or a hot pressing clamp. There is no need to tear and collect the paper bags 11, thus reducing production costs.

[0024] In order to facilitate the separation of paper bags 11 and convenient storage: a point breaking mechanism 7 is provided in front of or behind the paper bag tube forming mechanism 4, wherein there are various ways of point breaking processing, for example, the point breaking mechanism 7 includes a point breaking knife plate and a support plate that move up and down, and the coil passes between the point breaking knife plate and the support plate, wherein the coiled material is intermittently conveyed, and when the coil stops conveying, the point breaking knife plate descends and cooperates with the support plate to perform point breaking processing on the coiled material, and after processing, the coil continues to be conveyed, and the point breaking knife plate rises back to its position.

[0025] Alternatively, the point breaking mechanism 7 includes a point breaking knife roller 71 and a driving roller 72 which are rotatably arranged on a frame. The power source drives the point breaking knife roller 71 to rotate. A point breaking tool 711 is installed on the point breaking knife roller 71. The point breaking tool 711 is consistent with the axial direction of the point breaking knife roller 71 along the length direction (that is, the point breaking knife roller 71 is transversely arranged on the frame). The axial direction of the point breaking knife roller 71 is perpendicular to the conveying direction of the paper 10. The point breaking tool 711 performs point breaking in the transverse direction of the paper 10. The power source drives the driving roller 72 to rotate in coordination with the point breaking knife roller 71. The driving roller 72 and the point breaking knife roller 71 are arranged relatively parallel. There is a gap between the driving roller 72 and the point breaking knife roller 71 for the coil to pass through. When point breaking, the point breaking tool 711 is pressed against the driving roller 72. The gap facilitates the passage of the roll material. When the cutting tool 711 passes through the gap, it is pressed against the transmission roller 72 to cut the paper 10. The transmission roller 72 is a rubber roller to prevent the transmission roller 72 from colliding with the cutting tool 711.

[0026] During the transmission process of the roll paper, the dot breaking knife roller 71 rotates, and the paper 10 passes between the dot breaking roller and the driving roller 72. When the dot breaking knife 711 passes through the gap, the dot breaking knife 711 contacts the paper 10 or the paper bag 11 and cuts the paper 10 or the paper bag 11 transversely at a dotted line.

[0027] Example 1

[0028] When the point breaking mechanism 7 is arranged in front of the paper 10 roll forming mechanism: the bottom edge gluing mechanism also includes a bottom edge gluing member 2, and the side edge gluing mechanism includes a side edge gluing member 3. The bottom edge gluing member 2 and the side edge gluing member 3 can be a gluing roller or a gluing gun; the bottom edge gluing roller, the bottom glue drying member 21 and the side edge gluing member 3 are arranged on the frame along the conveying path. The bottom edge gluing member 2 first glues the bottom edge (horizontally) of the roll material, and then the bottom glue drying member 21 dries it, and then the side edge gluing member 3 glues the side edge (longitudinal) of the material. Drying the bottom edge first can prevent the bottom edge glue 8 water from contaminating other parts when the paper 10 is folded into a roll.

[0029] The point breaking mechanism 7 is arranged between the side gluing mechanism and the bottom gluing mechanism. Among them, the bottom glue gluing roller is rotatably arranged on the frame, and the bottom glue gluing roller has a gluing convex strip, and the bottom glue gluing roller is transmission-connected with the bottom glue driving member. There are multiple ways to gluing the bottom glue gluing roller. The bottom glue gluing roller is relatively arranged with a glue roller, and the gluing convex strip contacts the glue roller, and then the bottom edge of the material is glued as the bottom glue roller rotates; or a sponge strip is directly attached to the bottom glue roller, and the sponge strip contacts the glue, and the contact surface between the sponge strip and the paper 10 is the gluing convex strip. The side glue gluing part 3 is fixedly arranged on the left side of the frame, and the side glue gluing part 3 is a glue gun, which glues the left side of the paper 10.

[0030] The roll of paper is gradually released from the unwinding frame of the unwinding mechanism 1, and the bottom edge glue roller of the gluing mechanism glues the bottom edge of the paper 10. The bottom glue on the paper 10 is dried by the bottom glue drying member 21. Then, the paper 10 passes between the driving roller 72 and the point breaking knife roller 71. When the point breaking knife 711 passes through the gap, the point breaking knife 711 contacts the material and punctures the material with dotted lines (at this time, the paper 10 is as shown in FIG. Figure 3 As shown). The paper 10 with the dotted lines passes through the side glue-applying member 3 to glue the side of the paper 10, and then the paper 10 passes through the paper bag roll-forming mechanism 4 to fold the paper 10, and the side glue glues the two sides of the paper 10 into a roll. The rolled paper 10 passes through the bottom glue heat-sealing mechanism 5, and the dry bottom glue returns to the viscous flow state, and the bottom edge is glued and sealed. Finally, the reeling mechanism 6 reels the continuous roll paper bag 11 with the dotted lines 9.

[0031] Example 2

[0032] When the point breaking mechanism 7 is arranged behind the paper 10 forming mechanism: the point breaking mechanism 7 is arranged behind the heat sealing mechanism, and the transmission roller 72 drives the heat-sealed paper bag 11 to pass through the point breaking knife roller 71. Point breaking the heat-sealed material can effectively reduce the length of the point breaking knife 711 and reduce the cost. Among them, the point breaking knife roller 71 and the transmission roller 72 are arranged opposite to each other up and down, and the layout is reasonable, which facilitates the passage of the heat-sealed paper bag 11.

[0033] The roll of paper is gradually released from the unwinding frame of the unwinding mechanism 1, and the bottom edge gluing roller of the gluing mechanism glues the bottom edge of the paper 10. The bottom glue on the paper 10 is dried by the bottom glue drying part 21. The paper 10 passes through the side gluing part 3 to glue the side edge of the paper 10. Then the paper 10 passes through the paper bag tube forming mechanism 4 to fold the paper 10, and the side glue is used to glue the two sides of the paper 10 into a tube. The tube-formed paper 10 passes through the bottom glue heat sealing mechanism 5, and the dried bottom glue restores the viscous flow state, the bottom edge is sealed, and the paper bag 11 is initially formed. The bottom-sealed paper bag 11 passes between the driving roller 72 and the point-breaking knife roller 71. When the point-breaking knife 711 passes through the gap, the point-breaking knife 711 contacts the initially formed paper bag 11 and punctures the material with dotted lines (at this time, the paper bag 11 is as Figure 4 Finally, the reeling mechanism 6 reels the continuous paper bag 11 that has been cut, and the material is torn from the dotted line to form the final paper bag 11.
