Description

Technical Field

[0001] The utility model relates to the technical field of butyl rubber cutting technology, and particularly relates to a novel cutting cylinder structure. Background Technique

[0002] The working principle of a butyl rubber filling machine is that a circular container moves upward and sleeves outside the glue injection device. The motor drives the cutting arm to rotate. There was originally a cutting wire on the cutting arm, passing through the center of the glue outlet pipe, dividing the glue into two parts. The glue in the circular container is prone to generating air bubbles, which has a great impact on the quality of the glue. The rotation of the cutting arm drives the wire cutting to separate the glue in the circular container from the pressure plate. The air cylinder pushes the circular container to move downward, but there will be a phenomenon that it cannot be pushed. At this time, when injecting glue into the circular container, the glue enters the gap between the pressure plate and the circular container, filling this small space, affecting the glue injection work, and there will be air bubbles in the colloid, affecting the quality of the glue. Another problem is that it is easy to push the centrifugal film inside the straight cylinder upward, exposing the paper tube surface, and the glue adheres to the paper tube. A novel cutting cylinder structure is proposed for the above problems. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a novel cutting cylinder structure. The structure is novel. By setting a cutting knife at the lower end of the cylinder to cut the glue along the circumferential direction, this can prevent the glue from being divided into two halves and generating air bubbles during glue injection, and at the same time prevent the glue from adhering to the paper tube, and can effectively solve the problems in the background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A novel cutting cylinder structure, including a tee pipe, a cylinder, and a cutting knife. The cylinder is sleeved on the tee pipe from the lower end of the tee pipe and is rotationally connected to the tee pipe. A pulley is arranged on the outer surface of the upper end of the cylinder. An outer cutting knife steering sleeve is arranged on the inner side of the lower end of the cylinder. The outer cutting knife steering sleeve and the cylinder are fixed by screws. An inner cutting knife steering sleeve is arranged on the inner side of the outer cutting knife steering sleeve. The cutting knife is provided with a blade rotating shaft and a blade positioning shaft. A rotating shaft positioning notch is opened on the outer cutting knife steering sleeve. The blade positioning shaft is inserted into the rotating shaft positioning notch. The blade rotating shaft is rotationally connected to the inner cutting knife steering sleeve. The length of the cutting knife is greater than the radius of the tee pipe.

[0005] Further, a deep groove ball bearing I is arranged at the upper part between the tee pipe and the cylinder, and deep groove ball bearings II and III are arranged at the lower part between the tee pipe and the cylinder.

[0006] Further, a bearing pad and a shaft snap ring are respectively arranged on the upper side and the lower side of the deep groove ball bearing III. A cylinder shaft sleeve II is arranged below the shaft snap ring. A cylinder shaft sleeve I is arranged outside the deep groove ball bearing III.

[0007] Furthermore, an inner chamfer is provided on the inner side surface at the upper end of the inner cutting tool rotating sleeve, and a through hole is provided on the inner cutting tool rotating sleeve. The blade rotating shaft is rotatably connected to the through hole.

[0008] Furthermore, long holes are provided in the circumferential direction of the rubber cylinder bushing II, and bolts are provided on the outer cutting tool rotating sleeve. The upper ends of the bolts extend into the long holes.

[0009] Furthermore, a cutting line is provided on one side at the lower end of the rotating cylinder. Both ends of the cutting line are fixedly connected to the outer surface of the rotating cylinder through screws. The cutting line corresponds to the outer surface at the lower end of the three-way pipe. The cutting line is used to cut the rubber between the three-way pipe and the rotating cylinder to prevent the rubber from sticking.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. The structure is novel. By providing a cutting tool at the lower end of the rotating cylinder to cut the rubber in the circumferential direction, it is possible to prevent the rubber from being divided into two halves and generating air bubbles during glue injection, and at the same time prevent the glue from sticking to the paper tube.

[0012] 2. The cutting tool is designed as a hidden structure. As long as the cutting tool is unfolded during cutting, the structure is safer and more reliable. At the same time, the cutting tool is easy to disassemble and assemble, which is convenient for inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0024] Please refer to Figures 1-9 , the present invention provides a technical solution: a new type of rubber cutting rotating cylinder structure, including a three-way pipe 1, a rotating cylinder 3 and a cutting knife 7. The rotating cylinder 3 is sleeved on the three-way pipe 1 from the lower end of the three-way pipe 1 and is rotationally connected to the three-way pipe 1. A pulley 2 is arranged on the outer surface of the upper end of the rotating cylinder 3. The pulley 2 is connected to an external driving pulley through a belt, so as to drive the rotating cylinder 3 to rotate and realize cutting. An outer cutting knife turning sleeve 9 is arranged on the inner side of the lower end of the rotating cylinder 3. The outer cutting knife turning sleeve 9 and the rotating cylinder 3 are fixed by screws. When the rotating cylinder 3 rotates, it can drive the cutting knife turning sleeve 9 to rotate. An inner cutting knife turning sleeve 13 is arranged on the inner side of the outer cutting knife turning sleeve 9. A blade rotating shaft 15 and a blade positioning shaft 14 are arranged on the cutting knife 7. A rotating shaft positioning notch 17 is opened on the outer cutting knife turning sleeve 9. When the cutting knife turning sleeve 9 rotates, it can drive the cutting knife 7 to contract or expand. After the cutting knife 7 expands, it makes a circular motion driven by the rotating cylinder 3 and cuts from the circumferential direction of the rubber, which can prevent the rubber from being divided into two halves and generating bubbles during glue injection, and at the same time prevent the glue from sticking to the paper tube. The blade positioning shaft 14 is inserted into the rotating shaft positioning notch 17, and the blade rotating shaft 15 is rotationally connected to the inner cutting knife turning sleeve 13. The blade rotating shaft 15 serves as a rotating support point and plays a role in supporting the cutting knife 7. The length of the cutting knife 7 is greater than the radius of the three-way pipe 1, so as to complete the cutting of the rubber. Loosen the screws on the cutting knife 7, and the cutting knife 7 can be disassembled.

[0025] A deep groove ball bearing I 4 is arranged between the upper parts of the three-way pipe 1 and the rotating cylinder 3, and a deep groove ball bearing II 5 and a deep groove ball bearing III 6 are arranged between the lower parts of the three-way pipe 1 and the rotating cylinder 3. The deep groove ball bearing I 4, the deep groove ball bearing II 5 and the deep groove ball bearing III 6 respectively play a role in rolling support for the rotating cylinder 3.

[0026] On the upper and lower sides of the deep groove ball bearing Ⅲ6, there are respectively arranged a bearing pad 10 and a shaft snap ring 11. The bearing pad 10 separates the deep groove ball bearing Ⅱ5 and the deep groove ball bearing Ⅲ6. The shaft snap ring 11 is stuck in the annular groove of the three-way pipe 1, playing a role of elastically blocking the deep groove ball bearing Ⅲ6. Below the shaft snap ring 11, there is arranged a rotating cylinder bushing two 12, and on the outer side of the deep groove ball bearing Ⅲ6, there is arranged a rotating cylinder bushing one 8.

[0027] On the inner side surface of the upper end of the internal cutting tool turning sleeve 13, there is arranged an internal chamfer 16. The internal chamfer 16 reduces the inner circumferential area of the internal cutting tool turning sleeve 13, reduces the wear between it and the three-way pipe 1, reduces the resistance, and reduces the energy consumption. There is a through hole 18 opened on the internal cutting tool turning sleeve 13. The blade rotating shaft 15 is rotationally connected with the through hole 18, and is fixedly connected with the rotating cylinder bushing two 12 by a screw passing through the blade rotating shaft 15 and the through hole 18.

[0028] There are long holes 19 arranged in the circumferential direction of the rubber cylinder bushing two 12. There are bolts arranged on the external cutting tool turning sleeve 9, and the upper ends of the bolts extend into the long holes 19. The length of the long holes 19 just limits the unfolding and folding of the cutting tool 7, ensuring stable operation. For example, when the rotating cylinder 3 rotates forward for cutting, the cutting tool 7 is driven by the external cutting tool turning sleeve 9 to unfold. When the cutting is completed and the rotating cylinder 3 rotates reversely, the cutting tool 7 is driven by the external cutting tool turning sleeve 9 to contract and hide.

[0029] On one side of the lower end of the rotating cylinder 3, there is arranged a cutting line 20. Both ends of the cutting line 20 are fixedly connected with the outer surface of the rotating cylinder 3 by screws. The cutting line 20 corresponds to the outer surface of the lower end of the three-way pipe 1. The cutting line 20 is used to cut the glue between the three-way pipe 1 and the rotating cylinder 3 to prevent the glue from sticking.

[0030] The above shows and describes the basic principles, main features and advantages of the present utility model. Without departing from the spirit and scope of the present utility model, there are various changes and improvements to the present utility model, and these changes and improvements all fall within the scope of the present utility model claimed.
