Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art should fall within the protection scope of this utility model.

[0023] Please see Figures 1 to 3 This is a preferred embodiment of the present invention. The tape splicing mechanism includes a base 1, a heating module 2, and a tape splicing head 3 that can move up and down. The base 1 has a mounting groove 11, the heating module 2 is located in the mounting groove 11, the upper surface of the heating module 2 is flat, and the upper surface is exposed on the top surface of the base 1. The tape splicing head 3 is located above the heating module 2.

[0024] When splicing tapes, tape 100 is fed from the transverse direction ( Figure 1 and Figure 3 (The direction of the middle arrow indicates the conveying direction of tape 100). During the transverse movement of tape 100, the heating module 2 heats tape 100 to ensure tape 100's adhesion. During the heating process, the tape receiving head 3 presses tape 100 down to make it adhere to the upper surface of the heating module 2 and be fully heated. When changing materials, tape 100 is manually cut. This cycle is repeated to complete the production process.

[0025] Specifically, the base 1 has limiting steps 12 on both the left and right sides of the mounting groove 11, with the step surfaces of the limiting steps 12 being flush. The base 1 also has two limiting blocks 13, which are fixed to the left and right sides of the mounting groove 11 at positions opposite to the limiting steps 12. A channel for accommodating the tape 100 is provided between the limiting blocks 13 and the limiting steps 12, and the sides of the limiting blocks 13 adjacent to the step surfaces of the limiting steps 12 are flush. The limiting blocks 13 are locked to the base 1 by bolts 14. Each limiting block 13 has a slotted through hole 131, the major axis of which extends perpendicular to the step surface of the limiting step 12. The bolts 14 pass through the slotted through holes 131. By adjusting the locking position of the bolts 14 in the slotted through holes 131, tapes 100 of different widths can be accommodated.

[0026] Please refer to the following: Figures 4 to 6The base 1 is further provided with a support 15, and the belt connecting pressure head 3 comprises a pressure plate 31, a connecting column 32, a pin 33, a spring 34 and a guide sleeve 35. The connecting column 32 is perpendicular to the upper surface of the heating module 2, the pressure plate 31 is located at the bottom end of the connecting column 32 and is parallel to the upper surface of the heating module 2, the guide sleeve 35 is sleeved on the end of the connecting column 32 away from the pressure plate 31 and is fixed on the support 15. The guide sleeve 35 is provided with a “T”-shaped guide groove 351, which comprises a horizontal groove 3511 parallel to the upper surface of the heating module 2 and a vertical groove 3512 perpendicular to the upper surface of the heating module 2.

The pin 33 penetrates through the connecting column 32 and the guide groove 351 and is parallel to the upper surface of the heating module 2. The spring 34 is elastically compressed and clamped between the support 15 and the pressure plate 31.

[0027] When the belt is not connected, the pin 33 is located in the horizontal groove 3511 of the guide groove 351, the pressure plate 31 is suspended in the air, and the spring 34 is in a compressed state. When the belt is connected, the pin 33 is manually moved to move downward along the vertical groove 3512 of the guide groove 351, and in this process, the spring 34 is elongated under the action of elastic restoring force, thereby driving the pressure plate 31 and the connecting column 32 to move downward, so that the pressure plate 31 presses the adhesive tape 100. In this embodiment, the bottom surface of the pressure plate 31 is provided with knurling 311, so that the adhesive tape 100 is more firmly attached.

[0028] In order to avoid the influence of the heating module 2 on the surrounding temperature, there is a hollow gap between the inner side wall of the mounting groove 11 and the heating module 2. In this embodiment, the heating module 2 comprises a heat conduction sheet 21 and a heating sheet 22, and the heat conduction sheet 21 and the heating sheet 22 are stacked in the mounting groove 11 in a top-to-bottom manner, and the upper surface of the heat conduction sheet 21 is exposed outside the top surface of the base 1.

When the material is replaced, the piston of the gas cylinder 4 moves downward to press the adhesive tape 100 to fix the adhesive tape 100, so as to facilitate manual cutting of the adhesive tape 100. The use of the gas cylinder 4 to fix the adhesive tape 100 can save labor intensity and increase the efficiency of manual work. In addition, the above-mentioned adhesive tape connecting mechanism further comprises a K-type thermocouple 5, which is used to detect the heating temperature of the heating module 2, so as to avoid the influence of excessive or insufficient temperature on the adhesion of the adhesive tape 100.
