Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to a cutting device for plastic blow molding. Background Technology

[0002] Plastic blow molding technology is widely used in industries such as packaging and daily necessities due to its advantages of high efficiency and low cost. The trimming device, as a key piece of equipment in blow-molded product production, directly affects product quality and production efficiency. Its main function is to precisely remove excess scrap material from the blow-molded product, ensuring dimensional accuracy and appearance quality.

[0003] However, in actual production, traditional edge-cutting devices commonly suffer from waste accumulation when handling bottle nozzle edge-cutting operations. When the edge-cutting device runs continuously, a large amount of cut plastic waste cannot be discharged in a timely manner. This not only occupies workspace, affecting the operator's visibility and equipment maintenance, but may also obstruct the operation of the edge-cutting device due to waste entanglement in equipment parts, increasing the risk of equipment failure, reducing production efficiency, and requiring frequent shutdowns to clean up the waste, resulting in energy waste and increased production costs.

[0004] Therefore, a cutting device for plastic blow molding is proposed to solve the above problems. Utility Model Content

The fixing groove and positioning groove are formed on the surface of the base frame.

[0010] Preferably, a power cylinder is fixedly installed on the base frame behind the clamping frame. The power cylinder is used to drive the cutting assembly to cut the sprue of the blow-molded bottle.

[0011] In the design, the power cylinder fixedly installed on the base frame behind the clamping frame enables the cutting component to cut the sprue of the blow-molded bottle. The power cylinder provides linear driving force and is installed by bolts to the base frame.

[0012] Preferably, the cutting assembly includes a connecting rod that passes through the clamping frame, with the top of the connecting rod connected to the piston end of the power cylinder, and a cutting blade installed at the bottom of the connecting rod. The bottom of the cutting blade passes through a pre-reserved slot and falls into the receiving frame.

[0013] In the design, the connecting rod of the cutting component passes through the reserved slot of the clamping frame and is connected to the piston end of the power cylinder at the top and the cutting blade is installed at the bottom. This structure enables the linear motion of the power cylinder to be transmitted to the cutting blade for cutting.

[0014] The cutting assembly is designed to precisely cut the bottle neck. The connecting rod of the cutting assembly has a cylindrical structure and is fixedly connected to the piston end of the power cylinder.

A drive motor is driven on the blower and fixedly installed through a fixing groove.

[0016] In the design, the blower of the discharge assembly outputs strong air to the cutting blade inside the receiving rack. This method enables the discharge of residual waste material inside the receiving rack after the cutting edges are removed.

[0017] The discharge assembly has the function of efficiently cleaning waste. The blower of the discharge assembly adopts a volute structure. Its air outlet end is connected to the opening at one end of the receiving frame. After being positioned with the base frame through the positioning groove, it is fixed with bolts. The drive shaft of the blower is connected to the output shaft of the drive motor through a coupling. The drive motor is installed by being positioned with the base frame through the fixing groove and then fixed with bolts.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This utility model installs a clamping frame on the base frame and opens a reserved slot through the base frame on the clamping frame, so that the waste material cut by the cutting component can fall directly into the receiving frame below through the reserved slot;

[0020] Meanwhile, a discharge assembly is installed on the base frame, which can discharge the waste material remaining in the receiving rack, achieving efficient waste discharge. This solves the problems of traditional edge-cutting devices not being able to discharge waste material in time when cutting the bottle nozzle, which leads to occupying workspace, affecting equipment operation, and increasing maintenance costs.

The fixing grooves 112 and positioning grooves 113 are formed on the surface of the base frame 11.

[0036] Furthermore, a power cylinder 12 is fixedly installed on the base frame 11 behind the clamping frame 13. The power cylinder 12 is used to drive the cutting assembly 2 to cut the sprue of the blow-molded bottle.

[0037] Specifically, the power cylinder 12, which is fixedly installed on the base frame 11 behind the clamping frame 13, enables the cutting assembly 2 to cut the bottle nozzle after blow molding. The power cylinder 12 provides linear driving force and is installed by bolts to the base frame 11.

[0038] Furthermore, the cutting assembly 2 includes a connecting rod 21 that passes through the clamping frame 13. The top of the connecting rod 21 is connected to the piston end of the power cylinder 12, and a cutting blade 22 is mounted on the bottom of the connecting rod 21. The bottom of the cutting blade 22 passes through the reserved slot 131 and falls into the receiving frame 114.

[0039] Specifically, the structure in which the connecting rod 21 of the cutting assembly 2 passes through the reserved slot 131 of the clamping frame 13 and is connected to the piston end of the power cylinder 12 at the top and the cutting blade 22 is installed at the bottom realizes the function of transmitting the linear motion of the power cylinder 12 to the cutting blade 22 for cutting.

[0040] The cutting assembly 2 has the function of precisely cutting the bottle spout.

The bottom is connected to the cutting blade 22 by bolts, and the blade at the bottom of the cutting blade 22 can pass through the reserved slot 131 and fall into the receiving rack 114.

[0041] Example 3

[0042] To achieve efficient removal of residual waste material from the receiving rack after edge trimming, such as Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the discharge assembly 3 includes a blower 31, which is used to output strong air to the cutting blade 22 in the receiving rack 114. The air outlet of the blower 31 is connected to the opening at one end of the receiving rack 114. The blower 31 is fixedly installed through the positioning groove 113. A drive motor 32 is driven on the blower 31 and fixedly installed through the fixing groove 112.

[0043] Specifically, the blower 31 of the discharge assembly 3 outputs strong air to the cutting blade 22 inside the receiving rack 114. This method realizes the function of discharging the residual waste material inside the receiving rack 114 after cutting.
