Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a structure of a tape threading machine. Background Art

[0002] The tape threading machine belongs to a kind of packaging equipment, which usually includes a tape threading machine body and a traction head. The tape reel is installed on the tape reel of the tape threading machine body. One end of the packing tape is led out and connected to the traction head. The packing tape is wound around the product through the traction head to pack the product.

[0003] When the traction head stops moving, the tape reel also needs to stop moving. Otherwise, the packing tape on the tape reel will become loose. Usually, the friction between the packing tape and the panel of the tape threading machine is used to realize the braking of the tape reel on the existing tape threading machine. That is, when the traction head works, it pulls the packing tape to overcome the friction force, so as to pull out the packing tape. When the traction head stops working, the friction force makes the packing tape stop being pulled, and then the tape reel stops rotating. During the movement of the packing tape, there will be continuous friction between the packing tape and the panel of the tape threading machine, which will affect the strength of the packing tape on the one hand and cause wear of the panel of the tape threading machine on the other hand. At the same time, even when the packing tape stops moving, due to inertia, the tape reel (tape reel) will continue to rotate, resulting in the packing tape on the tape reel becoming loose and scattered, affecting subsequent use. Summary of the Utility Model

[0004] The utility model provides a structure of a tape threading machine with stable start and stop of the tape reel and fast braking response in order to solve the above problems existing in the prior art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A structure of a tape threading machine includes a frame. A tape reel support is arranged on the frame. A main shaft is arranged on the tape reel support. A tape reel assembly for storing a tape reel is arranged on the main shaft. The tape reel assembly is rotationally connected to the main shaft. A brake disc is fixedly arranged on one side of the tape reel assembly. A brake assembly is arranged outside the brake disc. One end of the brake assembly is rotationally connected to the tape reel support. The other end of the brake assembly is provided with a guide member for guiding the packing tape to the traction head. An elastic member for elastically pressing the brake assembly against the brake disc is arranged on the brake assembly. When the packing tape is pulled by the traction head and moves, the packing tape acts on the guide member to separate the brake assembly from the brake disc, and the tape reel assembly rotates under the traction force. When the packing tape stops moving, the brake assembly is elastically pressed against the brake disc under the action of the elastic member to stop the rotation of the tape reel assembly.

[0007] By adopting the above technical solution, the braking component is automatically pulled to rotate and the braking is released according to the movement of the packing belt. When the packing belt stops moving, under the action of the elastic component, the braking component automatically brakes the brake disc, and the overall structure is compact and stable, and the braking response is fast.

[0008] Preferably, the braking component includes a braking rod and a brake pad fixed on the braking rod. When the packing belt stops moving, the brake pad elastically abuts against the circumferential surface of the brake disc so that the tape reel component stops moving. The brake pad increases the braking friction force and further improves the braking stability.

[0009] Preferably, the braking rod includes a braking part for installing the brake pad and a braking arm connected to one end of the braking part. The other end of the braking arm is rotatably connected to the tape reel bracket, and the guiding component is configured as a guide wheel, and the guide wheel is arranged at the end of the braking arm; the braking part has a V-shaped structure, and the open end of the braking part faces the brake disc. The braking part is arranged in a V-shaped structure to increase the friction force during braking.

[0010] Preferably, the elastic component is configured as a tension spring. One end of the tension spring is connected to the braking arm, and the other end of the tension spring is connected to the tape reel bracket.

[0011] Preferably, a limiting component is arranged on the tape reel bracket. When the braking component rotates to a preset position under the pulling force of the packing belt, the braking component is limited by the limiting component.

[0012] Preferably, the tape reel component includes a first tape reel body and a second tape reel body. A first rotating seat rotatably connected to the main shaft is fixedly arranged on the first tape reel body, and a second rotating seat rotatably connected to the main shaft is fixedly arranged on the second tape reel body. A tape reel storage area for installing a tape reel is formed between the first tape reel body and the second tape reel body.

[0013] Preferably, the brake disc is rotatably connected to the main shaft, and the end face of the brake disc is fixedly connected to the first tape reel body; a handwheel is arranged on the main shaft outside the second tape reel body, and the handwheel is threadedly connected to the main shaft. The distance between the first tape reel body and the second tape reel body can be adjusted through the handwheel to adapt to the installation of tape reels with different widths.

[0014] Preferably, the lower end of the tape reel bracket is rotatably connected to the frame, a connecting seat is arranged between the tape reel bracket and the end of the main shaft, and an angle adjusting component for adjusting the angle of the tape reel bracket is arranged between the connecting seat and the frame. When replacing the tape reel, rotate the tape reel bracket to an inclined or horizontal state, loosen the handwheel, remove the second tape reel body, and then install the tape reel.

[0015] Preferably, the angle adjustment assembly is configured as a gas spring. The lower end of the gas spring is rotatably connected to the frame, and the upper end of the gas spring is rotatably connected to the connecting seat. When the gas spring extends, the tape reel bracket is vertically distributed with respect to the bottom of the frame. When the tape reel bracket is rotated outward to compress the gas spring, the tape reel bracket is inclined with respect to the frame.

[0016] Preferably, a housing for storing the drive chain is provided on one side of the frame where the tape reel assembly is located. The outer end of the drive chain extends out of the housing and is connected to the towing head. A guide seat and a second guide wheel are provided on one side of the housing facing the tape reel assembly. The end of the packing tape passes through the guide wheel, the guide seat, and the second guide wheel in sequence and then enters the housing and is connected to the towing head along the direction of the drive chain.

[0017] Therefore, the utility model has the beneficial effects of stable start and stop of the tape reel and fast braking response. BRIEF DESCRIPTION OF THE DRAWINGS

A limiting member 11 is provided on the tape reel support 2. When the brake assembly 6 rotates to a preset position under the pulling force of the packing tape 7, the brake assembly 6 is limited by the limiting member 11.

[0032] As Figure 9 and Figure 10As shown in the figure, on one side of the belt pulley assembly 4 on the frame 1, there is a housing 12 for storing the drive chain 13. The outer end of the drive chain extends out of the housing and is connected to the towing head 14. On the side of the housing 12 facing the belt pulley assembly 4, there is a guide seat 15 and a second guide wheel 16. The end of the packing belt 7 passes through the guide wheel, the guide seat 15, and the second guide wheel 16 in sequence, enters the housing, and is connected to the towing head 14 along the direction of the drive chain 13.

[0033] As Figure 5 and Figure 6 shown, the belt pulley assembly 4 includes a first belt pulley body 40 and a second belt pulley body 41. A first rotating seat 42 rotatably connected to the main shaft 3 is fixedly provided on the first belt pulley body 40.

A handle 22 for gripping is provided at the upper end of the belt pulley bracket 2. As Figure 7 shown, a triangular bracket is formed between the two ends of the gas spring and the rotation point at the lower end of the belt pulley bracket. When the belt pulley bracket is rotated outward, the gas spring is compressed at this time, so that the belt pulley bracket is rotated to Figure 8 the state shown.
