An adhesive tape feeding and pulling device

Abstract

This utility model relates to the technical field of tape traction equipment, specifically a tape feeding and traction device. The device includes a support frame with an open side. Inside the support frame is a vertically movable clamping plate used to press the end of the tape into the support frame. A control slot is provided at the top of the support frame, and a drive plate is fixedly connected to one side of the clamping plate. This utility model uses the clamping plate and support frame to fix the end of the tape. The movement of the support frame drives the tape end to move, allowing the traction rollers that guide the tape to separate in a smaller space.

Furthermore, because the entire end of the tape is fixed, the tape remains spread out during traction, preventing folding during manual traction.

Description

Technical Field

[0001] This utility model relates to the technical field of tape traction equipment, specifically a tape feeding and traction device. Background Technology

[0002] During the conveyor belt feeding process, one end of the conveyor belt needs to be torn off from the conveyor belt unloading wheel and passed between the traction rollers or guide rollers of the equipment. The traction rollers or guide rollers are used to assist in guiding and moving the conveyor belt and to continuously convey the conveyor belt.

[0003] In the prior art, such as the PET tape traction device proposed in patent application number "CN202111667605.2", a mounting frame is provided, a fixed frame is provided on the mounting frame, a traction roller is rotatably connected to the fixed frame, and an adjusting rod is provided on the fixed frame. The adjusting rod is located outside the traction roller, and when the tape is fed, the end of the tape needs to pass through the adjusting rod and the outside of the traction roller.

[0004] However, in the existing technology, when passing the tape end through the equipment or traction roller, the two corners of the tape end are usually pinched manually. This feeding method requires sufficient space for arm movement between the traction rollers or in the tape's path inside the equipment, which is inconvenient for traction of the tape in the limited space inside the equipment. Moreover, during the traction process, the tape may fold and stick together because the hands are close together, affecting the subsequent processing of the tape. Utility Model Content

[0005] The purpose of this invention is to provide a tape feeding and traction device to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A tape feeding and traction device includes a support frame with an open design on one side, and a pressing plate that can move up and down is provided inside the support frame. The pressing plate is used to press the end of the tape into the inside of the support frame.

[0008] The top of the support frame has a control slot. A drive plate is fixedly connected to one side of the clamping plate. A control rod is fixedly connected to the top of the drive plate at the control slot. Pulling the control rod up and down at the control slot will cause the clamping plate and the drive plate to move up and down together.

[0009] A blade mechanism is provided on one side of the support frame, which can move along the long side of the support frame. The blade mechanism is used to cut the end of the tape after traction is completed.

[0010] Preferably, a pressure spring is fixedly connected to the top of the inner wall of the support frame, and the bottom of the pressure spring is fixedly connected to the clamping plate.

[0011] Preferably, the top of the control rod is flush with the top of the support frame.

[0012] Preferably, two protrusions are fixedly connected to the top of the inner wall of the support frame, and a guide shaft with a regular hexagonal cross-section is fixedly connected between the two protrusions. A movable plate is slidably connected to the guide shaft, and the movable plate is fixedly connected to the blade mechanism.

[0013] Preferably, the blade mechanism includes a fixed plate fixed to one side of the movable plate, a toggle block fixedly connected to the top of the fixed plate, and a cutting blade fixedly connected to the bottom of the fixed plate, the two sides of the cutting blade being sharp surfaces.

[0014] Preferably, a protective plate is provided on one side of the support frame, and a strong magnet is fixedly connected to the inner surface of the protective plate.

[0015] Preferably, the bottom of the support frame is provided with a U-shaped groove, and a handle is fixedly connected to one side of the support frame.

[0016] The beneficial effects of this utility model are:

[0017] This invention uses a clamping plate and a support frame to fix the end of the tape. The movement of the support frame causes the end of the tape to move, allowing the traction rollers that guide the tape to separate in a smaller space. This allows the clamping plate and the end of the tape to pass between two close traction rollers, facilitating traction operations in the limited space of the equipment. At the same time, because the entire end of the tape is fixed, the tape can always remain spread out during traction, avoiding folding of the tape during manual traction, which would cause the tape to stick together and affect its subsequent use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 , Figure 2 and Figure 4 A tape feeding and traction device includes a support frame 1. One side of the support frame 1 is designed with an open type. A pressing plate 2 that can move up and down is provided inside the support frame 1. The pressing plate 2 is used to press the end of the tape inside the support frame 1. Then, by moving the support frame 1, the end of the tape is driven to move, and the movement of the end of the tape is pulled so that the end of the tape passes through the roller device.

[0028] like Figure 1 , Figure 2 and Figure 4 The top of the support frame 1 is provided with a control slot 3. A drive plate 5 is fixedly connected to one side of the clamping plate 2. A control rod 4 is fixedly connected to the top of the drive plate 5 and located at the control slot 3. When the control rod 4 is pulled up and down at the control slot 3, the drive plate 5 can move up and down together with the clamping plate 2.

[0029] like Figure 1 The top of the control rod 4 and the top of the support frame 1 are on the same horizontal plane, so they will not occupy the space above the support frame 1 and reduce the vertical height of the equipment.

[0030] like Figure 1 and Figure 4The support frame 1 has two guide rods 6 fixedly connected inside. The guide rods 6 pass through the drive plate 5, so that the drive plate 5 and the clamping plate 2 can only move up and down along the direction of the guide rods 6.

[0031] like Figure 1 and Figure 2 A pressure spring 7 is fixedly connected to the top of the inner wall of the support frame 1. The bottom of the pressure spring 7 is fixedly connected to the pressure plate 2, and applies downward pressure to the pressure plate 2.

[0032] like Figure 2 and Figure 3 Two protrusions 8 are fixedly connected to the top of the inner wall of the support frame 1. A guide shaft 9 is fixedly connected between the two protrusions 8. The cross-section of the guide shaft 9 is a regular hexagon. A movable plate 10 is slidably connected to the guide shaft 9. A blade mechanism is fixedly connected to one end of the movable plate 10. The blade mechanism can move with the movable plate 10 in the direction of the guide shaft 9 to cut the end of the tape pressed between the pressing plate 2 and the support frame 1.

[0033] like Figure 2 and Figure 3 The blade mechanism includes a fixed plate 11, which is fixed to one side of the movable plate 10. A toggle block 12 is fixedly connected to the top of the fixed plate 11, and a cutting blade 13 is fixedly connected to the bottom of the fixed plate 11. The two sides of the cutting blade 13 are sharp surfaces.

[0034] like Figure 2 and Figure 3 A protective plate 14 is provided on one side of the support frame 1. One end of the protective plate 14 is bent upward, and the blade mechanism is located between the protective plate 14 and the support frame 1.

[0035] like Figure 2 and Figure 3 A strong magnet 141 is fixedly connected to the inner surface of the protective plate 14. The fixed plate 11 is made of iron. When the blade mechanism moves to the inside of the protective plate 14, it can magnetically attract the fixed plate 11 to position the blade mechanism. The protective plate 14 also provides protection for the blade, improving the safety of the device.

[0036] like Figure 2 The bottom of the support frame 1 is provided with a U-shaped groove 101, which makes it easy to cut the end of the tape inside the support frame 1 and then use your fingers to squeeze the tape upward from the U-shaped groove 101 to easily tear off the tape stuck inside the support frame 1.

[0037] like Figure 1 A handle 102 is fixedly connected to one side of the support frame 1. By manually gripping the handle 102, the support frame 1 can be easily moved.

[0038] The working principle of the tape feeding and traction device provided by this utility model is as follows:

[0039] When belt traction is required, first unload the belt from the unloading pulley (e.g., Figure 5 The opening of the support frame 1 is set upwards. Then, the control lever 4 is pulled, which moves the pressure plate 2. At this time, a space is formed between the pressure plate 2 and the inner wall of the support frame 1. The support frame 1 is then moved upwards, so that one end of the tape on the feeding belt pulley moves relative to the pressure plate 2 and the inner wall of the support frame 1 (the non-adhesive side of the tape is the side close to the pressure plate 2, and the adhesive side is the side close to the inner wall of the support frame 1). Then, the control lever 4 is released, and the tension of the pressure spring 7 is used to push the pressure plate 2. The pressure plate 2 squeezes the end of the tape, and the tape end is glued to the inside of the support frame 1, thus fixing the tape end in the support frame 1.

[0040] Then, manually control the support frame 1 through the handle 102. The support frame 1 passes through two close traction rollers or other spaces inside the equipment where the tape needs to pass through, causing the tape end to move together. This guides the tape through the traction rollers or other spaces inside the equipment where the tape needs to pass through, thus pulling the tape end to the predetermined work position. After the tape end is bonded to other materials, the toggle block 12 above the fixing plate 11 is moved horizontally, causing the cutting blade 13 to move horizontally and cut off the tape end. The cut tape is then bonded inside the support frame 1.

[0041] Pull the control lever 4 again to separate the pressure plate 2 from the tape. Then, push the tape upward through the U-shaped slot 101 with your fingers to separate the tape support frame 1. Tear off the residual tape on the support frame 1 by holding the separation point for easy tape pulling next time.

[0042] Compared with related technologies, the tape feeding and traction device provided by this utility model has the following beneficial effects:

[0043] This invention uses a clamping plate 2 and a support frame 1 to fix the end of the tape. The movement of the support frame 1 causes the end of the tape to move, separating the traction rollers that guide the tape into a smaller space. This allows the clamping plate 2 and the end of the tape to pass between two close traction rollers, facilitating traction operations within the limited space of the equipment. At the same time, because the entire end of the tape is fixed, the tape can always remain spread out during traction, avoiding folding during manual traction that would cause the tape to stick together and affect its subsequent use.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
