Embodiment 1

[0029] Such as Figure 1~3 As shown, the heat seal strength detection equipment of the container lid film in this embodiment includes a base 100, on which a container fixing mechanism 1 for clamping the cup body 200 to be tested is provided, and the container fixing mechanism 1 1 is provided with a digital display tensioner 2 for detecting the heat seal strength when the cover film is torn, and a clamping mechanism that can tear the cover film from the vertical direction is connected to the bottom of the digital display tensioner 2 4.

[0030] Such as figure 2 and 3 As shown, the container fixing mechanism 1 includes a bottom plate 11 for carrying the cup, and the bottom plate 11 is connected with the base 100 through a sliding mechanism. The sliding mechanism includes a slideway 12 arranged on the base 100 and a slideway matching part (not shown) arranged at the bottom of the bottom plate 11 . Also be provided with certain height support 14 on base plate 11, be provided ...

Embodiment 2

[0037] The difference between this embodiment and Embodiment 1 is that the second driving device used to drive the container fixing mechanism to move horizontally in this embodiment is a stepped constant speed motor. The rotational speed set by the stepped constant speed motor is the same as the stepped constant speed motor used to drive the digital display tensioner, so as to ensure that the cover film is always in a vertical state with the cup mouth of the cup body during the upward tearing process.

[0038] When using a stepped constant speed motor to drive the container fixing mechanism, it is sufficient to set the corresponding up button, down button, speed button, and stop button on the base. The remaining parts are the same as those in Embodiment 1, and will not be repeated here.

[0039] The method for detecting the heat seal strength of the container lid film will be described below.

[0040] Wherein the manner of locating the cup to be detected is the same as that o...

Embodiment 3

[0042] The difference between this embodiment and Embodiment 1 is that the sliding mechanism in this embodiment is in the form of a pulley and a directional chute. Specifically, a horizontal orientation chute is arranged on the base, and two pulleys are arranged at the bottom of the bottom plate, and the pulleys cooperate with the orientation chute to realize the horizontal movement of the container positioning mechanism. The remaining parts are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a device and a method for detecting the heat seal strength of a container cover membrane. The device comprises a base, a first driving device, a clamping mechanism, a container positioning mechanism and a second driving device, wherein the base is provided with a chest expander; the first driving device is used for driving the chest expander; the bottom of the chest expander is connected with the clamping mechanism; the container positioning mechanism is positioned below the chest expander for clamping a container; the second driving device is used for driving the container positioning mechanism. According to the invention, the extension direction of the clamping mechanism of the device for detecting the heat seal strength of the container cover membrane is perpendicular to the container positioning mechanism so as to simulate the hand tearing motions, and detect the maximal heat seal strength value at the moment of start. The container positioning mechanism is applicable to cups with different shapes and sizes without frequent fixture replacement, is relatively wide in application, is light, simple and convenient to operate, is easy to detect, is accurate in reading, can be used for detecting the heat seal strength in the production process, and can control the heat seal stability of products. The detecting method enlarges the 15mm heat seal surface to the whole heat seal layer, so that the detection data are relatively accurate and comprehensive.

Description

technical field [0001] The invention relates to a heat-sealing strength detection device and a detection method thereof, in particular to a heat-sealing strength detection device and a detection method of a container cover film. Background technique [0002] At present, most cup products are sealed with a heat-sealing lid film. If the sealing firmness is too small, leakage will often occur and affect product quality; if the sealing firmness is too large, it will often be difficult to tear open, affecting the convenience of use for consumers. . The heat-sealing strength directly affects the product quality, so it is imperative to find a reasonable heat-sealing strength and improve product quality. [0003] However, the existing national standard can only refer to the detection method in GB1040. The detection method is: cut a sample with a fixed width (generally 15mm wide), and then stretch it at a specified speed to detect the heat seal strength of the fixed width. However...
