Description

Technical Field

[0001] The utility model relates to the technical field of continuous point-breaking devices, and more specifically to a bag-making continuous point-breaking device. Background Art

[0002] In the modern packaging industry, the continuous development of bag-making technology is of vital importance to improving production efficiency, ensuring product quality and meeting diverse market demands. The continuous point-breaking device used for bag-making is a key equipment in the bag-making process. Its performance and technical level directly affect the bag-making effect and production continuity. The existing continuous point-breaking device for bag-making is usually composed of a driving device and a point-breaking device and other structures. When in use, the driving device drives the bag body to move into the point-breaking device, and the point-breaking device is started to perform the point-breaking operation. Although this type of device can complete the point-breaking operation of bag-making, during the bag-body conveying process, the device mainly relies on the driving device to vertically position the bag body. Due to the flexibility of the bag body, the bag body may be offset during the conveying process, affecting the point-breaking quality of the bag body and subsequent production. In order to solve the shortcomings of the prior art, we propose a continuous point-breaking device for bag-making. Utility Model Content

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

[0011] The utility model provides a limit adjustment component, including positive and negative screw rods, which are rotated to drive two sliding frames threadedly connected on their outer surfaces to move relative to each other, and the sliding frame slides to drive the connecting rod to rotate, and the connecting rod rotates to drive the limit frame to slide on the upper surface of the base, so that the roller shaft one is attached to the two sides of the bag body, and then the threaded column is rotated to drive the limit plate to move downward, so that the roller shaft two is attached to the upper outer surface of the bag body.

[0012] The utility model provides a quick point breaking component, including a motor. The starting motor drives the connecting shaft to rotate on the inner surface of the hollow cover. The rotation of the connecting shaft drives the cam to fit the upper outer surface of the point breaking frame and rotate, thereby pushing the point breaking frame and the point breaking head to move downward and squeezing the spring at the same time. When the protruding position of the outer surface of the cam leaves the upper outer surface of the point breaking frame, the spring resets and drives the point breaking frame to rise. By utilizing the above structure, the starting motor drives the cam to rotate and push the point breaking frame and squeeze the spring at the same time, thereby achieving continuous point breaking of the point breaking head and quickly retracting it, preventing the point breaking head from damaging the bag body during the conveying process, and further improving the point breaking quality and working efficiency of the device.

[0020] As attached Figure 1 To Attachment Figure 4 The embodiment of the utility model provides a bag-making continuous point-breaking device, comprising a base 1, a limit adjustment component 2 is arranged on the upper side of the base 1, a quick point-breaking component 3 is arranged on the inner side of the limit adjustment component 2, a hollow cover 4 is fixedly installed on the middle part of the upper outer surface of the base 1, and a fixing block 5 is fixedly installed on the outer surface of one side of the hollow cover 4;

[0021] The limit adjustment assembly 2 includes a forward and reverse screw rod 21, the outer surface of the forward and reverse screw rod 21 is threadedly connected to a sliding frame 22, the inner side of the sliding frame 22 is symmetrically rotatably connected to a connecting rod 23, the outer wall of one end of the connecting rod 23 is rotatably connected to a limit frame 24, the inner wall of one side of the limit frame 24 is rotatably connected to a roller shaft 1 25, a threaded column 26 is threadedly connected to the middle part of the upper inner wall of the limit frame 24, the outer surface of the lower end of the threaded column 26 is rotatably connected to a limit plate 27, the lower inner wall of the limit plate 27 is rotatably connected to a roller shaft 28, and a sliding rod 29 is symmetrically fixedly installed on the upper outer surface of the limit plate 27.

[0022] Among them, the forward and reverse screw rods 21 are rotatably connected to the inner wall of the base 1, the sliding frame 22 slides on the inner cavity surface of the base 1, the limiting frame 24 slides on the upper outer surface of the base 1, and the sliding rod 29 is slidably installed on the upper inner wall of the limiting frame 24;

[0023] By rotating the forward and reverse screw rods 21, the two sliding frames 22 connected by threads on their outer surfaces are driven to move relative to each other. The sliding of the sliding frame 22 drives the connecting rod 23 to rotate. The rotation of the connecting rod 23 drives the limiting frame 24 to slide on the upper surface of the base 1, so that the roller shaft 1 25 fits on both sides of the bag body, and then the threaded column 26 is rotated to drive the limiting plate 27 to move downward, so that the roller shaft 2 28 fits on the upper outer surface of the bag body.

[0024] Wherein, the quick point breaking component 3 comprises a motor 31, a connecting shaft 32 is fixedly mounted on the outer surface of the output end of the motor 31, cams 33 are fixedly sleeved on the outer walls of both ends of the connecting shaft 32, the outer surface of the cam 33 is fitted with a point breaking frame 34, a point breaking head 35 is fixedly mounted on the lower outer surface of the point breaking frame 34, a spring 36 is fixedly sleeved on the lower outer wall of the point breaking frame 34, a fixing column 37 is fixedly sleeved on the lower inner wall of the spring 36, a point breaking platform 38 is arranged below the point breaking frame 34, the motor 31 is fixedly mounted with the inner wall of the fixing block 5, the connecting shaft 32 is rotatably connected to the inner surface of the hollow cover 4, the side of the point breaking frame 34 is fitted with the inner surface of the hollow cover 4, the fixing column 37 is fixedly mounted on the upper outer surface of the base 1, and the point breaking platform 38 is fixedly mounted in the middle of the upper outer surface of the base 1, and is located directly below the point breaking frame 34;

[0025] By starting the motor 31, the connecting shaft 32 is driven to rotate on the inner surface of the hollow cover 4. The rotation of the connecting shaft 32 drives the cam 33 to rotate in contact with the upper outer surface of the point breaking frame 34, thereby pushing the point breaking frame 34 and the point breaking head 35 to move downward, while squeezing the spring 36. When the protruding position of the outer surface of the cam 33 leaves the upper outer surface of the point breaking frame 34, the spring 36 resets and drives the point breaking frame 34 to rise.

[0028] The working process of the utility model is as follows:

[0029] The bag body is then transported to the upper outer surface of the base 1 by the driving device, and then the positive and negative screw rods 21 are rotated to drive the two sliding frames 22 threadedly connected on their outer surfaces to move relative to each other. The sliding frame 22 slides and drives the connecting rod 23 to rotate. The connecting rod 23 rotates and drives the limiting frame 24 to slide on the upper surface of the base 1, so that the roller shaft 1 25 is attached to the two sides of the bag body. Then the threaded column 26 is rotated to drive the limiting plate 27 to move downward, so that the roller shaft 28 is attached to the upper outer surface of the bag body. After completion, the motor 31 is started at the same time to drive the connecting shaft 32 to rotate on the inner surface of the hollow cover 4. The rotation of the connecting shaft 32 drives the cam 33 to fit the upper outer surface of the point breaking frame 34 and rotate, thereby pushing the point breaking frame 34 and the point breaking head 35 to move downward, realizing the point breaking operation on the bag body, and at the same time squeezing the spring 36. When the protruding position of the outer surface of the cam 33 leaves the upper outer surface of the point breaking frame 34, the spring 36 resets and drives the point breaking frame 34 to rise.
