Description

Technical Field

[0001] The present invention belongs to the technology of treating waste of mushroom production, and mainly relates to a device for breaking the plastic film of the outer package of waste mushroom bags. Background Art

[0002] Edible mushrooms, including auricularia auricula and various mushrooms, are a kind of food with rich nutrition and delicious taste. With the improvement of the living standard and quality of the people in our country, the demand for edible mushroom products is increasing continuously. The traditional cultivation methods can no longer meet the needs of their yield. Therefore, the technical method of cultivating edible mushrooms by using mushroom bags has developed rapidly. However, while this method provides sufficient edible mushroom products for the people, it also brings a large number of waste mushroom bags, which cause environmental pollution and the problem of how to deal with them. To solve the above problems, scientific research personnel have done a lot of research work. In recent years, the research on various waste mushroom bag recycling technologies has achieved initial results, pointing out the direction for the recycling of waste mushroom bags and turning waste into treasure.

[0003] Before recycling the contents of waste mushroom bags, it is necessary to remove the plastic film packaging on the outside of the mushroom bags. At present, it is mostly completed by manually cutting and removing each mushroom bag one by one, which has many problems such as low operation efficiency, high labor intensity, poor operation quality, and high operation cost.

[0004] At present, the applicant has developed a mechanical device for removing the plastic film of the outer package of waste mushroom bags, which preliminarily solves the problems existing in the above manual operation. However, the applicant believes that this device still has problems that should be solved, such as relatively complex structure, large floor area, small range of model selection for users, and few models. Summary of the Invention

[0005] The purpose of the present invention is to design an automatic cutting and milling device for breaking the plastic film of the outer package of waste mushroom bags with a new structure in combination with the actual needs of waste mushroom bag treatment, aiming to simplify the structure, reduce the floor area, improve the automation degree and operation efficiency, and provide new models for users to choose.

[0006] The object of the present invention is achieved as follows: A rotary belt assembly is installed on a device frame. A plurality of bacterial bag clamping assemblies are uniformly and fixedly installed on the rotary belt of the rotary belt assembly. On the front side of the device frame, on both outer sides of the rotary belt assembly, bacterial bag axial positioning baffles are respectively installed. In the middle part of the device frame, on both outer sides of the rotary belt assembly, end face disc cutters for bacterial bags are respectively installed. The distance between the end face disc cutters for bacterial bags on both sides is smaller than the distance between the bacterial bag axial positioning baffles on both sides. An end face cutter drive electric motor installed on the side of the device frame is connected to the cutter shaft of the end face disc cutter for bacterial bags. On the rear side of the device frame, above the bacterial bag clamping assembly, a cylindrical roller milling cutter for bacterial bags is installed. A cylindrical milling cutter drive electric motor installed on the side of the device frame is connected to the cutter shaft of the cylindrical roller milling cutter for bacterial bags. A rotary belt assembly drive electric motor installed on the rear end side of the device frame is connected to the rotary drive shaft of the rotary belt assembly. The bacterial bag clamping assembly is composed of an assembly seat, arc-shaped clamping plates, pin shafts and torsion springs. On the front and rear parts of the assembly seat, arc-shaped clamping plates are symmetrically and swingably hinged and installed through pin shafts respectively. The torsion spring is sleeved on the pin shaft. The two ends of the torsion spring are respectively in contact and positioning cooperation with the assembly seat and the arc-shaped clamping plate. The torsion spring makes the arc-shaped clamping plates symmetrically installed on the front and rear parts of the assembly seat in an open state, thus forming an automatic cutting, milling and breaking device for the outer packaging plastic film of waste bacterial bags.

[0007] The present invention has a novel, reasonable and simple structure, with a compact overall size, small floor area, high degree of automation, good operation effect and reliable use, providing a new selectable model for users. Description of the Drawings

[0015] The implementation scheme of the present invention will be described in detail below with reference to the accompanying drawings. An automatic cutting, milling and breaking device for the outer packaging plastic film of waste bacterial bags. A rotary belt assembly 2 is installed on a device frame 1. A plurality of bacterial bag clamping assemblies 3 are evenly and fixedly installed on the rotary belt of the rotary belt assembly 2. Bacterial bag axial positioning baffles 4 are respectively installed on the front side part of the device frame 1 and on the outer sides of both sides of the rotary belt assembly 2. Disc cutters 6 for end faces of bacterial bags are respectively installed on the middle part of the device frame 1 and on the outer sides of both sides of the rotary belt assembly 2. The distance between the disc cutters 6 for end faces of bacterial bags on both sides is smaller than the distance between the bacterial bag axial positioning baffles 4 on both sides. A driving electric motor 7 for the end face cutter installed on the side part of the device frame 1 is connected to the cutter shaft of the disc cutter 6 for the end face of the bacterial bag. A cylindrical roller milling cutter 8 for the bacterial bag is installed on the rear side part of the device frame 1 and above the bacterial bag clamping assembly 3. A driving electric motor 9 for the cylindrical milling cutter installed on the side part of the device frame 1 is connected to the cutter shaft of the cylindrical roller milling cutter 8 for the bacterial bag. A driving electric motor 10 for the rotary belt assembly installed on the rear end side part of the device frame 1 is connected to the rotary drive shaft of the rotary belt assembly 2. The bacterial bag clamping assembly 3 is composed of an assembly seat 3-1, an arc-shaped clamping plate 3-2, a pin shaft 3-3 and a torsion spring 3-4. Arc-shaped clamping plates 3-2 are symmetrically and swingably hinged and installed on the front and rear parts of the assembly seat 3-1 through the pin shaft 3-3. The torsion spring 3-4 is sleeved on the pin shaft 3-3. The two ends of the torsion spring 3-4 are respectively in contact and positioning cooperation with the assembly seat 3-1 and the arc-shaped clamping plate 3-2. The torsion spring 3-4 makes the arc-shaped clamping plates 3-2 symmetrically installed on the front and rear parts of the assembly seat 3-1 in an open normally-closed fit.

[0016] During operation, the slewing belt assembly drive electric motor 10, the cylindrical milling cutter drive electric motor 9, and the end face cutter drive electric motor 7 respectively drive the slewing belt assembly 2 to rotate, the cylindrical roller milling cutter 8 for the fungus bag and the end face disc cutter 6 for the fungus bag to rotate. The fungus bag 5 is successively loaded onto the fungus bag clamping assembly 3 at the front of the slewing belt assembly 2. Under the action of the self-weight of the fungus bag 5, the arc-shaped clamping plate 3-2, which is in a normally open fit at the initial position, rotates to close around the pin shaft 3-3 on the assembly seat 3-1, clamping and fixing the fungus bag 5 on the fungus bag clamping assembly 3 and moving together with the slewing belt assembly 2. Under the control of the axial positioning baffle 4 of the fungus bag, the end face disc cutter 6 for the fungus bag completes the sliding cutting and opening operation on both ends of the fungus bag 5. Then, the cylindrical roller milling cutter 8 at the rear completes the milling and opening operation on the plastic film at the cylindrical surface of the fungus bag 5. When the fungus bag 5 rotates with the slewing belt assembly 2 to the lower side of the slewing belt 2, under the combined action of the self-weight of the fungus bag 5 and the torque of the torsion spring 3-4, the arc-shaped clamping plate 3-2 in the closed state rotates in the reverse direction to open around the pin shaft 3-3 on the assembly seat 3-1, and the already cut and milled fungus bag 5 falls naturally for recovery, completing the fungus bag opening operation.
