[0001] The present invention relates to the technical field of beverage bottle recovery, in particular a crushing mechanism with multiple protections against water and a recovery machine for crushing and cutting beverage bottles. State of the art

[0002] With the increasingly widespread use of beverage bottle recovery devices, reducing transportation costs has become a new challenge for beverage recovery equipment. Currently, most beverage bottle recovery equipment on the market uses compression and flattening devices, which compress the recovered bottles into a flat shape to reduce their volume before they are sent to the recycling center to be crushed and cut by large crushing equipment. To further reduce transportation costs, integrating a small crusher directly into the beverage bottle recovery equipment to crush and cut the recovered bottles has become a new requirement.During grinding, if the shaft of the moving knife in the grinding assembly does not have adequate protection for the bearings, residual liquids and debris can easily damage the bearings on both sides of the blade shaft, preventing the grinder from functioning normally. Description of the invention

[0003] To solve the aforementioned problems, the objective of the present invention is to provide a grinding mechanism with multiple water protections and a recovery machine for grinding and cutting beverage bottles.

[0007] Preferably, said retaining ring and said sealing ring in the inner hole of the same bearing seat are arranged in a spaced manner, the point of connection between said water channel hole and the inner hole of the bearing seat being located between said retaining ring and said sealing ring.

[0008] Preferably, the end of said water channel hole away from the inner hole of said bearing seat communicates with said grinding chamber or with the space outside said grinding chamber, the height of the end of said water channel hole away from the inner hole of the bearing seat is less than the height of the connection point between said water channel hole and the inner hole of the bearing seat in the vertical direction; the connection point between said water channel hole and the inner hole of the bearing seat is located at the lowest point of the inner hole; the inner hole is a stepped hole, the diameter of the hole where said bearing is installed in the inner hole is less than the diameter of the hole where said seal is installed, the diameter of the hole where said seal is installed in the inner hole is less than the diameter of the hole where said retaining ring is installed.

[0009] Preferably, an arc-shaped filter is installed at the lower end of said grinding chamber, corresponding to the curvature of said movable knife assembly; the front end of said filter is articulated to the front of the lower end of the grinding chamber of said frame, or the rear end of said filter is articulated to the rear of the lower end of the grinding chamber of said frame, the other end being fixed to said frame.

[0010] Preferably, the two bearing seats are installed removably on the left and right sides of the grinding chamber respectively, and grooves Clearances are provided on the left and right walls of the grinding chamber at positions corresponding to the installation location of the bearing seats, used to install the moving knife assembly in the grinding chamber or to remove it from the grinding chamber.

[0011] Preferably, several movable knife blades are installed on the movable knife axis, the adjacent movable knife blades being arranged on the movable knife axis with a certain offset angle, the movable knife blades on both sides of the movable knife axis being progressively offset towards the middle movable knife blades, forming a V-shaped arrangement, the point of the V being oriented in the opposite direction to the rotation of the movable knife axis.

[0012] Preferably, a compartment assembly is installed under the grinding chamber on the frame, the compartment assembly comprising several compartment channels, each compartment channel being used to connect a recovery frame.

[0013] Preferably, the compartment channel inlets are arranged in rows at the end of a compartment guide plate facing the outlet of the grinding chamber, the compartment channel outlets being located above the corresponding recovery frames.

[0014] The present invention also relates to a recovery machine for crushing and cutting beverage bottles, using the multi-protection crushing mechanism against water as described above.

[0015] The advantages of the present invention are as follows: the present invention provides a grinding mechanism with multiple water protections and a recovery machine for grinding and cutting beverage bottles which, compared to the prior art, has at least the following technical advantages:

[0016] 1. A retaining ring is installed at each end of the movable knife shaft at its connection with the bearing seat, acting as a first barrier against water, isolating most of the liquids and debris; in addition, each bearing seat is drilled with a water channel hole communicating with the inner hole of the bearing seat, the connection point being located between the bearing and the retaining ring, allowing the liquid which enters the inner hole to be evacuated through the retaining ring, acting as a second barrier against water, thus minimizing the amount of liquid that can come into contact with the bearing, which helps to extend the life of the bearing and ensure stable long-term operation of the grinding mechanism.

[0017] 2. A sealing gasket is also installed on the movable knife shaft in the an internal hole, located between the water channel hole and the bearing, acting as a third barrier against water, preventing the bearing from coming into contact with the Liquid seeps through the gap in the retaining ring. Liquids or debris transmitted by the moving knife shaft are blocked by the retaining ring and discharged through the water channel hole, making it difficult for the seal to come into contact with the liquids, which also helps to extend the life of the seal and reduce the maintenance and operating costs of the crusher.

[0018] 3. The multiple movable knife blades on the movable knife axis are arranged with a certain offset angle in the direction of rotation of the axis, so that the grooves of the blades form an overall V-shaped arrangement. The liquids and debris after grinding are influenced by the screw effect of the blades, concentrating the debris and liquids towards the center, thus reducing the force exerted by the liquids and debris on the retaining ring, preventing as much as possible the liquids and debris from entering the space between the retaining ring and the sealing ring, which would damage the sealing ring.

[0019] 4. A compartment assembly is installed under the grinding chamber, It includes multiple compartment channels that guide the shredded debris into several collection frames, reducing the overall weight of each frame and allowing maintenance personnel to empty the frames with less effort. The compartment guide plate is removable and installed beneath the shredder; however, it is also possible to choose not to install this compartment guide plate. Without the compartment guide plate, the shredded material falls directly into a single collection frame beneath the shredder, and the large capacity of a single collection frame requires more effort to empty during maintenance.

Said retaining ring 5 and said sealing ring 9 in the inner hole of the same bearing seat 3 are arranged in a spaced manner, the point of connection between said water channel hole 6 and the inner hole of the bearing seat 3 being located between said retaining ring 5 and said sealing ring 9.A sealing ring 9 is also installed on the moving knife shaft 21 in the inner hole, located between the water channel hole 6 and the bearing 4, acting as a third barrier against water, preventing the bearing 4 from coming into contact with the liquid that seeps through the gap in the retaining ring 5. Liquids or debris transmitted by the moving knife shaft 21 are blocked by the retaining ring 5 and discharged through the water channel hole 6, making it difficult for the sealing ring 9 to come into contact with the liquids, which also helps to extend the service life of the sealing ring 9 and to reduce the maintenance and operating costs of the crusher.

[0038] With reference to figures 1 to 6, preferably, the end of said water channel hole 6 away from the inner hole of said bearing seat 3 communicates with said grinding chamber or with the space outside said grinding chamber, the height of the end of said water channel hole 6 away from the inner hole of the bearing seat 3 is less than the height of the connection point between said water channel hole 6 and the inner hole of the bearing seat 3 in the vertical direction.

[0039] With reference to Figures 1 to 6, preferably, the connection point between said water channel hole 6 and the inner hole of the bearing seat 3 is located at the lowest point of the inner hole. This can prevent the accumulation of liquid in the inner hole of the bearing seat 3.

[0040] With reference to figures 1 to 6, preferably, the inner hole is a stepped hole, the diameter of the hole where said bearing 4 is installed in the inner hole is less than the diameter of the hole where said seal 9 is installed, the diameter of the hole where said seal 9 is installed in the inner hole is less than the diameter of the hole where said retaining ring 5 is installed. This helps to prevent the liquid from coming into contact with the bearing 4.

[0041] With reference to Figures 1 to 9, preferably, the two bearing seats 3 are removably installed on the left and right sides of the grinding chamber, respectively, and clearance grooves 12 are provided on the left and right walls of the grinding chamber at positions corresponding to the installation location of the bearing seats, serving to install the movable knife assembly 2 into or remove it from the grinding chamber. A motor 13 is installed on the outer side of the frame 1, used to drive the rotation of the movable knife shaft 21.

[0042] With reference to Figures 1 to 9, preferably, several movable knife blades 22 are installed on the movable knife shaft 21, the adjacent movable knife blades 22 being arranged on the movable knife shaft 21 with a certain offset angle, the movable knife blades 22 on both sides of the movable knife shaft 21 being progressively offset towards the middle movable knife blades 22, forming a V-shaped arrangement (as illustrated in Figures 2 and 5), the point of the V being oriented in the direction opposite to the rotation of the movable knife shaft 21. The multiple movable knife blades 22 on the movable knife shaft 21 are arranged with a certain offset angle in the direction of rotation of the shaft, so that the grooves of the blades overall form a V-shaped arrangement.The liquids and debris after grinding are influenced by the screw effect of the blades, concentrating the debris and liquids towards the center, thus reducing the force exerted by the liquids and debris on the retaining ring 5; avoiding as much as possible that the liquids and debris. do not penetrate into the space between the retaining ring 5 and the sealing ring 9, which would damage the sealing ring 9.

[0043] With reference to figures 10 and 11, preferably, a compartment assembly 10 is installed under the grinding chamber on the frame 1, the compartment assembly 10 comprising several compartment channels 101, each compartment channel 101 being used to connect a recovery frame 11.

The compartment guide plate is installed removably beneath the grinder; of course, it is also possible to choose not to install this compartment guide plate. Without the compartment guide plate, the ground material falls directly into a single recovery frame 11 beneath the grinder, the large capacity of a single recovery frame 11 requiring more effort to empty during maintenance.

[0044] With reference to Figures 11 and 12, a recovery machine for crushing and cutting beverage bottles uses the multi-protection water-resistant crushing mechanism described above. This ensures that its crushing mechanism can be used stably in the long term, thus guaranteeing the long-term stability of this recovery machine for crushing and cutting.

[0045] The present invention operates according to the following principles:

[0046] During grinding, the retaining ring 5, located on the side of the inner hole of the bearing seat 3 facing the other bearing seat 3, blocks liquids and debris. Even if liquids and debris pass through the retaining ring 5, they can be discharged through the water channel hole 6 communicating with the inner hole. In addition, a sealing gasket 9 is installed on the side of the bearing 4 near the retaining ring 5, providing an additional blocking effect against liquids, thus completely preventing the bearing 4 from coming into contact with liquids and debris. This ensures that the movable knife shaft 21 can operate stably in the long term.The bottles, after being identified, transported and sorted in the recovery machine for crushing and cutting beverage bottles, are guided into the crushing chamber of this crushing mechanism to be crushed, either by the opposite rotation of two sets of movable knife assemblies 2 which cut. The beverage bottles are crushed either by the cooperation between the moving knife assembly 2 and the fixed knife assembly 7. During the rotation of the moving knife assembly 2, the multiple V-shaped moving knife blades 22 concentrate the debris and liquids towards the center of the moving knife axis 21, thus better preventing debris and liquids from entering the inner hole beyond the retaining ring 5. After crushing, the debris falls into the compartment assembly 10, then into the corresponding compartment channels 101 to be collected in the appropriate recovery frames 11.
