Unless otherwise mentioned, the singular form of the term can include the plural form, and it cannot be understood as the number of one.

[0028] Please refer to Figure 1 and Figure 2 The cutting device 100 for the PPH plastic storage tank in the preferred embodiment of the application comprises a base 110 (not shown in the figure), a mounting frame 120, a cutting blade 130, a driving mechanism 140, a limiting rod 150, and a positioning assembly 160.

[0029] The base 110 has opposite front and rear ends 111 and 112. The mounting frame 120 is mounted on the base 110 and is slidable in the direction in which the front and rear ends 111 and 112 point to each other. When the cutting device 100 for the PPH plastic storage tank is located on a horizontal plane, the direction in which the front and rear ends 111 and 112 point to each other is the horizontal direction, so the mounting frame 120 is slidably mounted on the base 110 in the horizontal straight direction.

[0030] The cutting blade 130 is rotatably mounted on the mounting frame 120. The driving mechanism 140 is in transmission connection with the cutting blade 130 and is used to drive the cutting blade 130 to rotate. The limiting rod 150 is arranged on the mounting frame 120. The limiting rod 150 can be integrally formed with the mounting frame 120 or fixedly connected with the mounting frame 120 through welding, screwing, etc.

[0031] The positioning assembly 160 comprises a positioning connecting rod 161 and a positioning roller 162. One end of the positioning connecting rod 161 is rotatably mounted on the mounting frame 120, and the other end is provided with the positioning roller 162.

[0032] The positioning connecting rod 161 is operable to swing the positioning roller 162 between a first preset position and a second preset position. When the positioning roller 162 is located at the first preset position, the positioning roller 162 is located at a side of the cutting blade 130 facing away from the rear end 112 and is used to be in contact with the outer wall of the tank mold 300. When the positioning roller 162 is located at the second preset position, the positioning roller 162 is used to abut against the limiting rod 150 when the distance between the cutting blade 130 and the tank mold 300 is less than or equal to the first preset distance, so as to lock the mounting rack 120 on the base 110.

[0033] When it is necessary to cut the PPH plastic tank 200 to be cut, the PPH plastic tank 200 to be cut is aligned with the cutting blade 130, and the positioning roller 162 is located at the first preset position. Then, the mounting rack 120 is pushed by an external force or a mechanical driving manner to drive the cutting blade 130 to move along the direction from the rear end 112 to the front end 111 until the positioning roller 162 contacts the outer wall of the tank mold 300, and the driving mechanism 140 is started. The driving mechanism 140 can also be started before the positioning roller 162 contacts the tank mold 300. Then, the mounting rack 120 is continuously pushed to drive the cutting blade 130 to move along the direction from the rear end 112 to the front end 111, so as to cut the PPH plastic tank 200 to be cut by the rotating cutting blade 130, and the positioning connecting rod 161 drives the positioning roller 162 to rotate along the direction from the front end 111 to the rear end 112 under the pushing of the tank mold 300 until the positioning roller 162 abuts against the limiting rod 150. At this time, the positioning roller 162 is located at the second preset position, and the positioning roller 162 is clamped between the limiting rod 150 and the outer wall of the tank mold 300, so as to lock the mounting rack 120 on the base 110, thereby stopping the cutting of the PPH plastic tank 200.

[0034] When the positioning roller 162 is located at the second position, the distance between the cutting blade 130 and the tank mold 300 is less than or equal to the first preset distance. In actual application, the first preset distance can be set to a very small value, for example, 2 mm or 3 mm, by the limiting rod 150. Such a small allowance can be quickly completed by manual cutting or manual breaking, and the cutting blade 130 will not damage the tank mold 300, thereby improving the production efficiency and safety of the PPH plastic tank 200.

[0035] Moreover, when the cutting depth increases, the positioning roller 162 rolls on the outer wall of the tank mold 300, and the positioning roller 162 can ensure that the distance between the cutting blade 130 and the tank mold 300 is accurately controlled even if the outer wall of the tank mold 300 is not flat, thereby improving the production safety.

[0036] In some embodiments, the cutting device 100 for the PPH plastic storage tank further comprises a distance sensor 170 mounted on the mounting frame 120. The distance sensor 170 is configured to collect distance information between the cutting blade 130 and the storage tank mold 300, and send a trigger signal to the driving mechanism 140 to stop working when the distance information shows that the distance is less than or equal to a second preset distance. The second preset distance is less than the first preset distance. Specifically, the first preset distance is 2-3 mm, and the second preset distance is 1-2 mm.

[0037] Therefore, in actual application, even in the extreme case that one or more of the positioning roller 162, the positioning link 161 and the limiting rod 150 is deformed, the distance sensor 170 will immediately send a trigger signal to the driving mechanism 140 to stop working when the cutting blade 130 is at the second preset distance from the storage tank mold 300, so that the cutting blade 130 stops rotating, thereby further reducing the probability of the cutting blade 130 directly cutting the storage tank mold 300, and further improving the production safety of the PPH plastic storage tank 200.

[0038] In some embodiments, the positioning assembly 160 further comprises an elastic member (not shown in the figure). The elastic member is configured to provide an elastic force that can drive the positioning link 161 to rotate the positioning roller 162 in a direction pointing from the rear end 112 to the front end 111. When the positioning roller 162 is at the first preset position, the positioning roller 162 is located below the connection between the positioning link 161 and the mounting frame 120. The elastic member can be a tension spring, a torsion spring, an elastic metal sheet, etc.

[0039] Therefore, the positioning roller 162 is at the first preset position when it is not subjected to other external forces (e.g. the pushing force of the PPH plastic storage tank 200), and at this time the positioning roller 162 can be maintained below the connection between the positioning link 161 and the mounting frame 120 by the elastic force provided by the elastic member, thereby adjusting the posture of the positioning roller 162 to facilitate control of the cutting depth.

[0040] Meanwhile, when the positioning roller 162 reaches the second preset position under the pushing of the storage tank mold 300 and the mounting frame 120 slides in a direction pointing from the front end 111 to the rear end 112, the elastic force provided by the elastic member can also automatically reset the positioning roller 162.

[0041] In some embodiments, the positioning assembly 160 further comprises a limiting block (not shown in the figure) mounted on the mounting frame 120. When the positioning roller 162 is at the first preset position, the limiting block contacts the side of the positioning link 161 away from the rear end 112.

[0042] The limiting block is used to limit the first preset position of the positioning roller 162, so as to reduce the situation that the positioning roller 162 is swung excessively by the positioning connecting rod 161, thereby ensuring that the positioning roller 162 can accurately reach the first preset position each time, improving the control accuracy of the cutting equipment 100 for the PPH plastic storage tank, and further improving the production safety of the PPH plastic storage tank 200.

[0043] In some embodiments, the guide 180 is arranged on the base 110. The mounting frame 120 is slidably arranged on the guide 180 in the direction in which the front end 111 and the rear end 112 point to each other. The guide 180 can be a guide rail arranged on the base 110, a guide groove formed on the base 110, etc. The guide 180 is mainly used to guide the sliding direction of the mounting frame 120, so as to improve the cutting accuracy and the control accuracy of the cutting equipment 100 for the PPH plastic storage tank, and is beneficial to further improving the production safety and the production efficiency of the PPH plastic storage tank 200.

[0044] In some embodiments, the cutting equipment 100 for the PPH plastic storage tank further comprises a rotating handle 190 and a transmission assembly 201. The rotating handle 190 is in transmission connection with the mounting frame 120 through the transmission assembly 201. The rotating handle 190 is reversibly rotatable, so as to drive the mounting frame 120 to slide in the direction in which the rear end 112 points to the front end 111 or in the direction in which the front end 111 points to the rear end 112.

[0045] Therefore, when the PPH plastic storage tank 200 to be cut needs to be cut, the worker reversibly rotates the rotating handle 190, so as to drive the mounting frame 120 to slide the cutting blade 130 in the direction in which the rear end 112 points to the front end 111, so as to realize the depth cutting of the PPH plastic storage tank 200 to be cut. When the cutting is completed, the worker reversibly rotates the rotating handle 190, so as to drive the mounting frame 120 to slide the cutting blade 130 in the direction in which the front end 111 points to the rear end 112, so as to realize the resetting of the cutting equipment 100 for the PPH plastic storage tank.

[0046] In some embodiments, the transmission assembly 201 comprises a transmission screw (not shown in the figure) and a transmission screw hole (not shown in the figure) formed on the mounting frame 120. The transmission screw is rotatably arranged on the base 110, one end of the transmission screw is screwed into the transmission screw hole, and the other end of the transmission screw is fixedly connected with the rotating handle 190. The transmission screw hole can be a threaded hole formed on the mounting frame 120, or can be a threaded hole of a transmission nut welded on the mounting frame 120.

[0047] The transmission screw is screwed into the transmission screw hole to form a lead screw mechanism, so as to convert the rotary motion of the rotary handle 190 into linear motion of the mounting frame 120, improve the transmission precision of the transmission assembly 201, and further improve the cutting precision of the cutting equipment 100 for the PPH plastic storage tank.

[0048] In some embodiments, the cutting equipment 100 for the PPH plastic storage tank further comprises a protective cover 202. The protective cover 202 is mounted on the mounting frame 120 and covers one end of the cutting blade 130 close to the rear end 112. The arrangement of the protective cover 202 can prevent the splashing of debris generated during cutting from hurting people, and further improve the production safety of the PPH plastic storage tank 200.

[0049] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered within the scope of the present disclosure.

[0050] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
