Description
Technical Field
The invention relates to recycling technology of recycling bottles, in particular to waste label removing equipment in recycling of recycling bottles, and more particularly relates to a recycling label removing machine for recycling glass bottles.
Background
Liquid products are usually put on the market by taking bottles as carriers, and the shapes of the bottles for containing liquid are various, but the bottles can be divided into three types of plastic bottles, ceramic bottles and glass bottles according to the molding materials, wherein the glass bottles have the characteristics of specific shape, difficult damage, scratch resistance, reusability and the like. Along with popularization of the environment-friendly and energy-saving concepts and production cost saving of enterprises, after liquid products taking glass bottles as carriers are put on the market, after the liquid products are consumed and used, the glass bottles serving as the carriers are usually recycled, reused, such as beer glass bottles, beverage glass bottles, condiment glass bottles and the like.
Before the glass bottle filled with the liquid product is put on the market, a label (or a bottle label) for identifying the source and information of the product needs to be arranged on the bottle body of the glass bottle, and in order to enable the label to be conveniently, efficiently and economically wrapped and formed on the bottle body of the glass bottle, the label is usually fixed on the surface of the bottle body in an annular non-adhesive mode, such as the most common annular polyvinyl chloride film label fixed on the surface of the bottle body in a heat shrinkage mode.
As such, recycled glass bottles are typically provided with old labels corresponding to the lot information, which are certainly not truly and effectively reflective of the recycled product information, which is obsolete. That is, the recycling of glass bottles requires the removal of waste labels, cleaning of the bottles, sterilization, and other processes to be completed before they are put on the recycled market. Therefore, the removal of the waste labels on the bottle body of the recycled glass bottle is a key ring for recycling in the recycling process.
At present, the removal of the waste labels fixed in an annular and non-adhesive mode on the recycled glass bottle in the industry is mainly realized in a traditional single operation mode, namely, after a worker takes the recycled glass bottle, a blade is firstly used for marking a tearing opening on the waste labels of the recycled glass bottle, and then the blade is put down to manually tear the waste labels, so that the waste labels on the recycled glass bottle are torn, peeled and removed at the tearing opening. Although the waste labels on the glass bottles can be effectively removed and recovered, the technical problems of low operation efficiency and high production cost exist, the effective control of enterprises on the production cost is not facilitated, and the clean and orderly management of the enterprise production environment is also not facilitated.
In view of this, in recent years, various techniques for removing waste labels in recycling of recycled glass bottles have been studied in the industry, and most of research results are directed to removal of paper old labels adhered and fixed on the surface of recycled glass bottles. There are few techniques disclosed for removing the old label that is attached to the surface of the recycled glass bottle in a ring-shaped, non-adhesive manner (particularly, a ring-shaped polyvinyl chloride film label that is attached to the surface of the bottle body in a heat-shrinkable manner).
The Chinese patent literature discloses an automatic bottle label stripper named as 'beverage bottle label stripper' (publication No. CN 203600467, publication day 2014, publication day 5 and publication day 21), which is characterized in that a recovery bottle is horizontally placed in a separation cavity with a certain inclination, and the recovery bottle is orderly dropped from top to bottom under the stirring of a plurality of groups of hobbing cutters and brush rollers which are sequentially driven in the separation cavity, so that the waste labels on the orderly dropped recovery bottle are removed. Although the technology can remove the waste label fixed in an annular and non-adhesive mode on the recovery bottle to a certain extent, the technology has the technical problems of low operation efficiency, poor effectiveness, poor reliability, poor universality and the like, and the technology is mainly characterized in that:
1. The recovery bottles are transversely placed at the feed inlet one by one manually; the recovery bottle with continuous feeding is easy to accumulate and block at the blocking part (namely, wavy arc surface) of the separation cavity, so that the subsequent feeding and the operation of equipment are influenced, and if the single feeding is carried out, the operation efficiency is influenced;
2. the hob and the brush roller need to stir the recovery bottle to move downwards when marking and brushing marks, so that in order to ensure that the recovery bottle moves downwards smoothly, the hob and the brush roller have limited acting force on the waste labels of the recovery bottle, and marking and label removing treatment are difficult to be effectively realized on each recovery bottle, otherwise, equipment can cause faults such as blockage and the like;
3. the acting force of the hob and the brush roller on the recovery bottle realizes hard extrusion on the recovery bottle, so that the fragile recovery bottle is easy to be extruded and exploded, and the recovery bottle is easy to be blocked or broken in the downward moving and falling process;
4. it is necessary to provide the recovery bottles with a corresponding roundness in order to cause the recovery bottles to fall in order in the separation chamber, that is to say, its operation is limited to circular recovery bottles, not polygonal recovery bottles including square ones.

In the conveying process, the bottom of the recovered glass bottle 6 is abutted against the bottle pushing plate 13 on the conveying chain plate 12, so that the conveying chain plate 12 can form forward pushing force on the recovered glass bottle 6 to overcome the operation resistance.
The marking mechanism 2 is arranged on a frame 11 of the chain conveyor 1, corresponding to a conveying channel on the chain conveyor 1. The marking mechanism 2 marks the moving recovered glass bottles 6 conveyed by the chain conveyor 1 in a two-sided clamping manner.
The marking mechanism 2 is mainly composed of marking assemblies arranged on both sides of the chain conveyor 1. Specifically, the marking assembly on each side mainly comprises a first base 21, a first rotating shaft 22, a first swinging frame 23, a knife holder 24 and a blade 25.

The first swinging frame 23 is long, the rear part of the first swinging frame 23 is connected with the upper end of the first rotating shaft 22, the front part of the first swinging frame 23 extends forwards, and an inverted L shape is formed between the first swinging frame 23 and the first rotating shaft 22; an arc-shaped waist-shaped groove is arranged on the inner side of the front part of the swing frame I23. The outer end of the knife holding frame 24 is hinged to the front part of the bottom side of the first swinging frame 23, the outer end of the knife holding frame 24 is assembled in a waist-shaped groove of the front part of the first swinging frame 23 through an adjusting screw, and under the action of a hinge shaft and the adjusting screw, the knife holding frame 24 can realize swinging adjustment or fixed assembly on the bottom side of the first swinging frame 23; the inner end of the holder 24 extends obliquely rearward above the conveyor flight 12, and the centerline of the holder 24 forms an angle of about 30 ° to 60 °, such as 45 °, with the centerline of the conveyor flight 12 in a plane.

The marking assemblies on both sides of the chain conveyor 1 are arranged symmetrically substantially along the longitudinal center line of the conveying chain plate 12, and the marking assemblies on both sides are connected together by elastic members 26, such as coil springs, on opposite swinging frames to form the marking mechanism 2. The marking assemblies on both sides of the marking mechanism 2 form a through passage with a distance smaller than the diameter of the recovered glass bottles 6 above the conveying chain plate 12, that is, the distance between the blades 25 of the marking assemblies on both sides is smaller than the diameter of the recovered glass bottles 6; when the recovered glass bottles 6 conveyed by the conveying chain plates 12 pass through the passage, the neck and belly large structure of the recovered glass bottles 6 guide the bottle bodies to form good contact with the blades 25 at the two sides, so that the blades 25 at the two sides scratch the waste labels on the surface of the bottle bodies of the recovered glass bottles 6, and the tearing opening is usually positioned at the front edge of the waste labels, even through the front and rear parts. Therefore, when the recovered glass bottle 6 with the large neck and belly is used as a cam, the marking assemblies on the two sides correspondingly generate outward swinging rotation when passing through the passing channel, and the marking assemblies on the two sides reset under the action of the first elastic piece 26 when the recovered glass bottle 6 passes out of the passing channel. In order to slow down the restoring force of each side marking assembly under the action of the first elastic piece 26, a buffer bracket extending downwards is arranged at the bottom of the first swinging frame 23 of each side marking assembly, a limiting rod 27 facing the chain conveyor frame is arranged on the inner side surface of the bottom of the buffer bracket, and a flexible or hydraulic suction part is arranged between the limiting rod 27 and the frame 11 of the chain conveyor 1.
The label removing mechanism 3 is composed of two sets which are sequentially arranged at the upper and lower sides and are sequentially arranged on the chain conveyor frame 11 at the lower side of the label marking mechanism 2, and each set of label removing mechanism 3 corresponds to a conveying channel on the chain conveyor 1. Each set of label removing mechanism 3 carries out friction label removing treatment on the recovery glass bottles 6 in motion conveyed by the chain conveyor 1 in a mode of clamping at two sides.

Specifically, the label removing assembly on each side mainly comprises a second base 31, a second rotating shaft 32, a second swinging frame 33, a friction shaft 34, a friction body 35 and a second motor 36. The second base 31 is fixed to the frame 11 of the chain conveyor 1. The lower end of the second rotating shaft 32 is fixed on the second base 31, and the upper end of the second rotating shaft 32 extends to the obliquely upper side of the conveying chain plate 12 of the chain conveyor 1. The second swinging frame 33 is triangular, the rear part of the second swinging frame 33 is connected with the upper end of the second rotating shaft 32 through a bearing, the front part of the second swinging frame 33 extends forwards, and the second swinging frame 33 and the second rotating shaft 32 are in an inverted L shape. The friction shaft 34 is vertically assembled at the front part of the second swinging frame 33 through a bearing, the upper end of the friction shaft 34 extends out of the top surface of the second swinging frame 33, the bottom end extends out of the bottom surface of the second swinging frame 33, the upper end of the friction shaft 34 is connected with a driven belt pulley, and the lower end of the friction shaft 34 is connected with the friction body 35. The second motor 36 is reversely arranged at the rear part of the second swinging frame 33 through a bracket, the output shaft of the second motor 36 is connected with a driving belt pulley, the driving belt pulley is connected with a driven belt pulley at the upper end of the friction shaft 34 through a belt, and the friction shaft 34 drives the friction body 35 to generate circumferential rotary motion under the driving of the second motor 36. The friction body 35 is a round steel wire or replaced by steel wire balls, and the peripheral wall of the friction body 35 is a friction cutting surface; the edge of the friction body 35 extends above the conveying chain plate 12, and the horizontal center height of the friction body 35 corresponds to the radius of the recovered glass bottles 6 moving on the chain conveyor 1, namely, the radius is half of the vertical height of the recovered glass bottles 6 on the conveying chain plate 12.
The label removing assemblies on two sides of the chain conveyor 1 are symmetrically arranged along the longitudinal central line of the conveying chain plate 12 basically, and the label removing assemblies with two side groups which are symmetrical are connected together through two elastic pieces 37-such as spiral springs-on opposite swinging frames to form a set of label removing mechanism 3. The two side label removing components of each label removing mechanism 3 form a through passage with a distance smaller than the diameter of the recovered glass bottle 6 above the conveying chain plate 12, that is, the distance between the friction bodies 35 of the two side label removing components is smaller than the diameter of the recovered glass bottle 6; when the recovered glass bottle 6 conveyed by the conveying chain plate 12 passes through the passage, the neck and belly large structure of the recovered glass bottle 6 guides the bottle body to form good contact with the friction bodies 35 at two sides, so that the friction bodies 35 at two sides tear, peel and remove the waste label on the surface of the bottle body of the recovered glass bottle 6 to carry out friction label removing treatment, and the sequence of the friction label removing treatment is from front to back.
