Description

Technical Field

[0001] The utility model relates to the field of full-automatic bag making equipment, in particular to an environmentally friendly film-coated paper bag processing production line. Background Art

[0002] Traditional paper bags have poor waterproof and leak-proof functions, so a type of laminated paper bag has emerged. This paper bag can be used as a packing bag or garbage bag and is widely used in catering, logistics, high-speed rail, aviation and other industries. The production process of the laminated paper bag uses hot-stamping to seal the edges and bottoms, making it waterproof and leak-proof.

[0003] The cutting (punching) process in the traditional paper bag processing is a step-by-step cutting process. The paper knife or punching device cuts or punches during the pause period of the stepping motor (conveying paper bags) under the action of the cam and spring. In addition, the traditional paper bag hot stamping process uses the up and down movement of the cam to perform horizontal ironing on the paper bags. This horizontal ironing method requires the paper bags to pause and iron during the transportation process. The above processing process is time-consuming and labor-intensive, and cannot achieve continuous operation, resulting in its output and quality cannot be guaranteed. Summary of the Invention

[0004] Therefore, the utility model is an environmentally friendly coated paper bag processing production line, which can realize the continuous processing of paper bags from raw materials to finished products. The utility model achieves the above purpose through the following technical solutions:

[0005] An environmentally friendly film-coated paper bag processing production line, which comprises: a feeding rack, a deflection correction mechanism, a tube-forming mechanism, an edge ironing mechanism, a horizontal ironing mechanism, a puncture and cutting mechanism, a bag collecting mechanism, and a rolling mechanism. The feeding rack is located at the front end of the entire production line, the deflection correction mechanism is located at the rear end of the feeding rack, the rear end of the deflection correction mechanism is provided with a tube-forming mechanism, the rear end of the tube-forming mechanism is equipped with an edge ironing mechanism, the rear end of the edge ironing mechanism is provided with a horizontal ironing mechanism, the horizontal ironing mechanism comprises: a fixed frame, a hot ironing roller, and a heating block. The horizontal ironing mechanism is installed on the film-coated paper bag processing production line through the fixed frame, a horizontal ironing assembly is installed on the inner side of the fixed frame, the horizontal ironing assembly consists of two hot ironing rollers, a pair of heating blocks are installed on the outer circumference of each hot ironing roller, a puncture and cutting mechanism is installed on the rear end of the horizontal ironing mechanism, the puncture and cutting mechanism can meet the production needs of both single paper bags and continuous roll paper bags, and the bag collecting mechanism and the rolling mechanism are located at the rear end of the entire production line.

[0006] Preferably, the puncture cutting mechanism includes: a roller, a knife edge, a flat-edged knife, and a puncture knife. A pair of knife edges are installed on the outer circumference of the roller. The knife edge can be installed with a flat-edged knife, a puncture knife, or only one puncture knife. The two knife edges are symmetrically arranged on the outer circumference of the roller.

[0007] Preferably, the edge ironing mechanism includes: a cylinder, an ironing bar, and a temperature controller; the lower end of the cylinder is connected to the upper end of the ironing bar, and the temperature controller is installed on one side of the ironing bar. The ironing bar is a heating element and the temperature can be adjusted after power is turned on. The temperature controller can control the temperature of the ironing bar.

[0008] Preferably, 2 or 3 groups of horizontal ironing components can be installed according to the production speed requirements, and each group of horizontal ironing components has the same ironing position for each group of paper bags.

[0009] Preferably, the two heating blocks are symmetrically arranged on the outer peripheral surface of the hot ironing roller and rotated 180 degrees. When the paper bag passes through the upper and lower hot ironing rollers, it is clamped and hot ironed by the heating blocks of the two hot ironing rollers.

[0010] Beneficial effects of the utility model:

[0011] 1. This utility model can realize the continuous processing of paper bags from raw materials to finished products, achieving a major breakthrough in output and quality. Under the premise of ensuring the same quality, the output is increased by two to three times, thereby improving production efficiency;

[0012] 2. In the existing hot-stamping production process of coated paper bags, the conveying speed of the paper bags should not be too fast. The production line of the utility model changes the original cam-type up-and-down hot-stamping method to a continuous horizontal hot-stamping method with rotating hot-stamping rollers, which greatly improves production efficiency. By setting up two or three sets of horizontal hot-stamping components, the hot-stamping quality of the paper bags is not reduced without increasing production costs.

[0013] 3. The puncture and cutting mechanism of the utility model changes the traditional cutting method driven by a stepper motor in the cutting / punching process, and uses the cutting and puncturing method of roller rotation to solve the problem of pausing the processing during the cutting / punching process, thereby significantly improving production efficiency.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, so that it is easy for those skilled in the art in the art to which the present invention belongs to to implement these embodiments. However, the present invention can also be implemented in various different forms. Therefore, the present invention is not limited to the embodiments described below. In addition, in order to more clearly describe the present invention, parts that are not connected to the present invention will be omitted from the accompanying drawings.

[0023] like Figure 1 As shown, an environmentally friendly coated paper bag processing production line includes: a loading rack 1, a deviation correction mechanism 2, a tube forming mechanism 3, an edge ironing mechanism 4, a horizontal ironing mechanism 5, a puncture and cutting mechanism 6, a bag collecting mechanism 7, and a rewinding mechanism 8;

[0024] The loading rack 1 is located at the front end of the entire production line and is used for loading paper bag raw materials. The correcting mechanism 2 is located at the rear end of the loading rack 1. The function of the correcting mechanism 2 is to ensure that the position of the paper does not shift during the transportation of the paper bag.

[0025] like Figure 1 、 4 As shown, the rear end of the deviation-correcting mechanism 2 is provided with a tube-forming mechanism 3, and the paper bag raw material is conveyed to the edge ironing mechanism 4 through the tube-forming mechanism 3 and is basically formed into a roll-shaped paper roll;

[0026] The rear end of the tube forming mechanism 3 is provided with a side ironing mechanism 4, which includes: a cylinder 41, an ironing row 42, and a temperature controller 43;

[0027] The lower end of the cylinder 41 is connected to the upper end of the ironing plate 42, and the ironing plate 42 can be driven to move together by the upward and downward extension of the cylinder 41;

[0028] The ironing plate 42 is a heating element, and its temperature can be adjusted after it is powered on. After it is powered on, the ironing plate 42 can press the overlapping edge of the coated paper.

[0029] The temperature controller 43 can control the temperature of the ironing board 42, and the temperature is set according to the running speed and thickness of the coated paper roll;

[0030] like Figure 1 、 5As shown, the rear end of the edge ironing mechanism 4 is provided with a horizontal ironing mechanism 5, which includes: a fixing frame 51, a heating block 52, and a hot ironing roller 53;

[0031] The horizontal ironing mechanism 5 is installed on the coated paper bag processing production line through a fixing frame 51, and the horizontal ironing mechanism 5 is located inside the fixing frame 51;

[0032] A horizontal ironing assembly is installed on the inner side of the fixing frame 51. The horizontal ironing assembly is composed of two hot ironing rollers 53. A pair of heating blocks 52 are installed on the outer circumference of each hot ironing roller 53. The two heating blocks 52 are symmetrically arranged on the outer circumference of the hot ironing roller 53, rotated 180 degrees. When the paper bag passes through the upper and lower hot ironing rollers 53, it is clamped and hot ironed by the heating blocks 52 of the two hot ironing rollers 53, so that the inner film of the paper bag is ironed and bonded.

[0033] Preferably, as an implementation method, two or three sets of horizontal ironing components can be installed according to the production speed requirements. Each set of horizontal ironing components heats each group of paper bags at the same position, which not only improves the horizontal ironing effect of the paper bags, but also allows the paper bags to be ironed without stopping during the processing process, thereby improving the production efficiency of the paper bags.

[0034] like Figure 1 、 6 As shown, the rear end of the horizontal ironing mechanism 5 is equipped with a puncture cutting mechanism 6, which includes: a roller 61, a knife edge 62, a flat knife 63, and a puncture knife 64;

[0035] A pair of blades 62 are installed on the outer circumference of the roller 61. The two blades 62 are symmetrically arranged on the outer circumference of the roller 61 rotated 180 degrees. According to actual production needs, the blades 62 can be equipped with a flat blade 63 and a piercing blade 64. The production line can produce single paper bags, and the piercing blade 64 and the flat blade 63 can pierce and cut the paper bags. Alternatively, only one piercing blade 64 can be installed, and the production line can produce continuous roll paper bags, and the piercing blade 64 can pierce the paper bags.

[0036] The bag collecting mechanism 7 and the rewinding mechanism 8 are located at the rear end of the entire production line. When the production line needs to produce a single paper bag, the puncture and cutting mechanism 6 and the bag collecting mechanism 7 cooperate with each other to realize the collection of a single paper bag. When the production line needs to produce a continuous roll of paper bags, the puncture and cutting mechanism 6 and the rewinding mechanism 8 cooperate with each other to realize the rewinding of the continuous roll of paper bags.

[0037] The utility model can be divided into two production modes according to production needs: a single paper bag production mode and a roll paper bag production mode;

[0038] The working principle of processing a single paper bag in this utility model:

[0039] S1: The loading rack 1 conveys the raw material of the coated paper bag to the barrel forming mechanism 3, and the raw material of the coated paper bag starts to move. The raw material of the coated paper bag is pressed into a barrel by the barrel forming mechanism 3;

[0040] S2: The rolled paper moves from the roll forming mechanism 3 to the edge ironing mechanism 4. The downward extension and contraction of the cylinder 41 on the edge ironing mechanism 4 drives the ironing row 42 to move downward. The ironing row 42 heats the overlapping edge of the coated paper web, melting the film of the coated paper web in the overlapping edge and bonding the coated paper webs on the overlapping edge together. The ironing row 42 continuously presses and irons the overlapping edge of the coated paper web. The ironed and bonded coated paper web is then conveyed to the horizontal ironing mechanism 5.

[0041] S3: The hot ironing roller 53 on the horizontal ironing mechanism 5 rotates. When the coated film roll passes the position of the heating block 52, the heating block 52 on the hot ironing roller 53 melts and presses the coated film roll.

[0042] S4: After the horizontal ironing process, the coated roll enters the subsequent puncture cutting mechanism 6 station. At this time, the puncture cutting mechanism 6 is simultaneously equipped with a puncture knife 64 and a flat knife 63. The puncture knife 64 and the flat knife 63 cut and puncture the coated roll respectively, so that the coated roll is formed into a single paper bag. Figure 2 The puncture cutting process is shown;

[0043] S5: The puncture and cutting mechanism 6 cooperates with the bag collecting mechanism 7 to collect individual paper bags.

[0044] The working principle of this utility model for processing continuous roll paper bags:

[0045] S1, S2, S3: The steps are the same as the working principle of processing a single paper bag;

[0046] S4: After the horizontal ironing process, the coated roll enters the subsequent puncture and cutting mechanism 6 station. At this time, the puncture and cutting mechanism 6 is only equipped with a puncture knife 64. The puncture knife 64 punctures the coated roll without cutting it, so that the coated roll forms a continuous paper bag. Figure 3 The puncture process is shown;

[0047] S5: The puncture cutting mechanism 6 cooperates with the rewinding mechanism 8 to collect the continuous roll of paper bags.
