Description

TECHNICAL FIELD

[0001] The utility model belongs to the biodegradable bag processing technical field, and concretely relates to biodegradable bag processing cold cutting equipment. BACKGROUND

[0002] With the increasing environmental awareness, the market demand of biodegradable bags as an environmentally friendly packaging material is rapidly growing, and the biodegradable bags are made of materials that can be naturally decomposed and can be decomposed into harmless substances under certain conditions by the action of microorganisms, reducing the long-term pollution of traditional plastic bags to the environment.

[0003] In the production process of biodegradable bags, after the heat sealing of the biodegradable bags is completed, the equipment is used to cut and separate the biodegradable bags with the same length, and the cut material is the single biodegradable bag. The traditional cutting method, such as hot cutting, will change the properties of the biodegradable material at high temperature. The biodegradable material has a specific molecular structure and physical and chemical properties. High-temperature hot cutting can easily cause local hardening and brittleness of the material. This change in properties will reduce the flexibility and tensile strength of the biodegradable bag, affecting the overall quality and service life of the bag. Therefore, the cold cutting method is used to process the biodegradable bag in the prior art.

[0004] However, in some cutting equipment using the cooling method in the prior art, the cutting knife is difficult to accurately control the cutting knife descending distance when cutting the biodegradable bag due to the imperfect design of the cutting mechanism. When the cutting knife descending distance is too much, the cutting knife is easy to cut the conveying belt used to convey the biodegradable bag, causing the damage of the conveying belt, increasing the equipment maintenance cost and downtime. When the cutting knife descending distance is too small, the biodegradable bag cannot be completely separated, affecting the production efficiency and product quality. In view of this, the utility model is proposed. UTILITY MODEL CONTENTS

[0005] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a biodegradable bag processing cold cutting equipment that can overcome the above problems or at least partially solve the above problems.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: a cold-cutting device for processing biodegradable bags, including a machine body, and further including: a bracket, fixedly installed above the machine body; telescopic cylinders, symmetrically installed on the bracket; a mounting plate, fixedly connected between the telescopic ends of the two telescopic cylinders; a cutter, installed on the lower side of the mounting plate; a limiting component for limiting the biodegradable bags, installed on both sides of the mounting plate; a feeding conveyor belt and a discharging conveyor belt, installed on the machine body and located on both sides of the cutter; a support plate, fixedly installed on the machine body and located between the feeding conveyor belt and the discharging conveyor belt; the support plate has a cutting groove for cooperating with the cutter; and a receiving plate, fixedly installed on the end of the machine body near the discharging conveyor belt.

[0007] To facilitate the closure of the grooves on the support plate and prevent the biodegradable bag from moving into the grooves and affecting its movement, a sealing plate is symmetrically connected to the opening of the grooves via a pivot. The upper surface of the sealing plate is flush with the upper surface of the support plate, and a torsion spring is connected between the pivot and the support plate.

[0008] To facilitate sealing the gap between the sealing plates so that the biodegradable bag can pass through more smoothly, adhesive strips are fixedly connected to the adjacent sides of both sealing plates.

[0009] Furthermore, the limiting component includes a limiting plate and a telescopic part. The limiting plate is symmetrically arranged on both sides of the cutter, and the lower end of the limiting plate is lower than the lower end of the cutter. The telescopic part is arranged between the limiting plate and the mounting plate.

[0010] To facilitate the flattening and tightening of the biodegradable bag and prevent wrinkles caused by uneven flattening from affecting the cutting quality of the cutter, the limiting plate and the mounting plate are rotatably connected. A flattening roller is rotatably connected to the lower end of the limiting plate. The telescopic part is an arc-shaped telescopic rod with internal tension elasticity. The two ends of the telescopic part are fixedly connected to the mounting plate and the limiting plate, respectively. The two limiting plates are initially arranged in a figure-eight shape.

[0011] To facilitate flexible assembly and disassembly of the cutter, a mounting plate is fixedly connected to the upper end of the cutter, and a slot for use with the mounting plate is provided on the mounting plate.

[0012] To further ensure the stability of the connection between the cutter and the mounting plate, a first magnetic plate is fixedly connected to the upper end of the insert plate, and a second magnetic plate that is magnetically attracted to the first magnetic plate is fixedly connected inside the slot.

[0013] In order to facilitate the flexible movement of the device without affecting the stability of the device, further, self-locking universal wheels are installed at the four corners of the bottom of the body.

[0014] After the above technical scheme, the utility model discloses the following beneficial effects compared with prior art: the utility model discloses the bearing plate and the slot are set up between two conveyors, and the biodegradable bag is positioned by the limiting assembly, so that the cutter can cut the biodegradable bag smoothly, and the problem that the cutter descending too much causes damage to the conveyor does not need to be considered, and the cutter descending distance adjustment problem existing in the cutting process of traditional equipment is effectively solved.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical scheme and advantage of the embodiments of the utility model more clear, the technical scheme in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the utility model, and the following embodiments are used to illustrate the utility model, but not to limit the scope of the utility model.

[0024] Embodiment 1:

[0025] With reference to Figures 1-5, The utility model provides a kind of biodegradable bag processing cold cutting equipment, including body 1, further comprising: support 6, fixedly installed above body 1;Telescopic cylinder 7, symmetrically installed on support 6;Mounting plate 8, fixedly connected between the telescopic end of two telescopic cylinders 7;Cutting knife 9, installed on the lower side of mounting plate 8;For the limiting of biodegradable bag, limiting assembly is installed on both sides of mounting plate 8;Feeding conveyor belt 2, discharging conveyor belt 3, installed on body 1, and located on both sides of cutting knife 9;Support plate 5, fixedly installed on body 1, and located between feeding conveyor belt 2 and discharging conveyor belt 3;Support plate 5 is provided with cutting groove 501 matched with cutting knife 9;Material receiving plate 4, fixedly installed on one end of body 1 close to discharging conveyor belt 3.

[0026] Limiting assembly includes limiting plate 10 and telescopic part 11, limiting plate 10 is symmetrically arranged on both sides of cutting knife 9, the lower end of limiting plate 10 is lower than the lower end of cutting knife 9, and telescopic part 11 is arranged between limiting plate 10 and mounting plate 8.

[0027] When it is needed to cut and separate the biodegradable bags connected together to make them into individual biodegradable bags, first, the biodegradable bags are placed on feeding conveyor belt 2, and feeding conveyor belt 2 will convey the biodegradable bags to the direction of cutting knife 9, when the biodegradable bags reach the cutting position, i.e. the connecting part of two biodegradable bags moves onto support plate 5 and is located above cutting groove 501, telescopic cylinder 7 starts to work, and telescopic cylinder 7 drives mounting plate 8 to move downward, and the limiting assembly on both sides of mounting plate 8 descends, and limiting plate 10 in limiting assembly contacts and presses the biodegradable bags under the action of telescopic part 11 to limit them, so as to ensure the stable position of the biodegradable bags during cutting, and with the continuous descending of mounting plate 8, cutting knife 9 penetrates through the biodegradable bags and cuts into cutting groove 501 on support plate 5, since support plate 5 is located between feeding conveyor belt 2 and discharging conveyor belt 3, cutting knife 9 will not contact the conveyor belts during cutting, so as to avoid the damage to the conveyor belts, and cutting knife 9 cuts and separates the biodegradable bags, and the cutting action is completed.

[0028] After cutting, telescopic cylinder 7 drives mounting plate 8 to ascend, cutting knife 9 and limiting plate 10 leave the biodegradable bags, and discharging conveyor belt 3 will convey the cut biodegradable bags to material receiving plate 4, and then workers can arrange the cut biodegradable bags on material receiving plate 4.

[0029] The limiting assembly can accurately limit the biodegradable bags before cutting, so as to ensure the accurate cutting position and the neat cutting edge, and improve the cutting quality of the biodegradable bags.

[0030] By arranging support plate 5 and cutting groove 501 between the two conveyor belts and reasonably designing the cutting mechanism, the damage of cutting knife 9 to the conveyor belts is avoided, and the service life of the equipment is prolonged.

[0031] Embodiment 2

[0032] With reference to Figures 1-5 , the biodegradable bag processing cold cutting equipment is basically the same as that in Embodiment 1, and further has: the opening of the cutting groove 501 is symmetrically connected with a sealing plate 502 through a rotating shaft, the upper surface of the sealing plate 502 is flush with the upper surface of the supporting plate 5, and the rotating shaft is connected with the supporting plate 5 through a torsional spring. The torsional spring is a structure commonly used in the art and is a very mature prior art on the market, and therefore is not shown in the figure. When the biodegradable bag moves from the feeding conveyor belt 2 to the side of the discharging conveyor belt 3 through the supporting plate 5, the sealing plate 502 can close the cutting groove 501 on the supporting plate 5, thereby avoiding the biodegradable bag moving into the cutting groove 501 and affecting the movement of the biodegradable bag, and effectively ensuring the smoothness of the biodegradable bag when moving.

[0033] The side adjacent to the two sealing plates 502 is fixedly connected with a rubber strip 503, as shown in Figure 3 In order to ensure that the two sealing plates 502 can rotate smoothly, there must be a certain gap between the two sealing plates 502. Through the arrangement of the rubber strip 503, the gap between the sealing plates 502 can be blocked, so that the biodegradable bag can pass more smoothly, and the end of the biodegradable bag is prevented from moving into the cutting groove 501 through the gap between the sealing plates 502, thereby effectively ensuring the stable movement of the biodegradable bag.

[0036] When the positions of the two biodegradable bags move to the position directly below the cutting knife 9, the mounting plate 8 can be driven to move downward by the telescopic cylinder 7. In the process of driving the cutting knife 9 and the limiting plate 10 to move downward, the flattening roller 12 installed at the lower end of the limiting plate 10 will first contact the biodegradable bag. With the continuous downward movement of the mounting plate 8, the flattening roller 12 will roll to both sides under the tension of the tensile spring, thereby flattening and tensioning the biodegradable bag, so as to avoid the biodegradable bag being wrinkled due to not being flattened, thereby affecting the cutting quality of the cutting knife 9.

[0037] Embodiment 4

[0038] With reference to Figures 1-5, the cutting knife 9 is fixedly connected with the first magnetic plate 14, and the second magnetic plate 15 that is mutually magnetized with the first magnetic plate 14 is fixedly connected in the slot, through the setting of the first magnetic plate 14 and the second magnetic plate 15, the insertion plate 13 can be stabilized in the slot, further guaranteeing the stability of the connection between the cutting knife 9 and the mounting plate 8.

[0039] The upper end of the insertion plate 13 is fixedly connected with the first magnetic plate 14, and the second magnetic plate 15 that is mutually magnetized with the first magnetic plate 14 is fixedly connected in the slot, through the setting of the first magnetic plate 14 and the second magnetic plate 15, the insertion plate 13 can be stabilized in the slot, further guaranteeing the stability of the connection between the cutting knife 9 and the mounting plate 8.
