[0001] The application relates to the technical field of a solid beverage filling machine, in particular to an auxiliary clamping device of a solid beverage filling machine. BACKGROUND

[0002] The package of the solid beverage in strip-shaped packaging is called a granule strip, and when the solid beverage filling machine performs granule strip filling production, the hot sealing device capable of moving up and down and clamping each other is used to heat seal and clamp the granule strip filled with material, and then the granule strip is released after being clamped and pulled down, and the hot sealed granule strip is cut by the cutting device below, so that the granule strip filling and packaging operation of the solid beverage is realized through repeated operation.

[0003] In actual production, although the downward movement of the granule strip is driven by the clamping and downward movement of the hot sealing device, after the hot sealing device releases the granule strip, the granule strip still has a slight downward displacement, which will cause the hot sealing position of the granule strip to be misaligned after a plurality of production accumulations. Since the package of the granule strip is printed in advance, the misalignment of the hot sealing position will cause a batch of substandard solid beverage granule strips. CONTENT OF THE INVENTION

[0016] The sliding block can be moved up to the position where the pawl A engages with the ratchet wheel A.

[0017] Optionally, a plurality of rollers are arranged on the side wall of the sliding block facing the friction plate, the circumferential outer wall of the roller is made of rubber material and abuts against the friction plate, and the roller rotates only when the sliding block moves to the topmost end or the lowest end.

[0018] Optionally, the circumferential outer wall of the roller is provided with a strip-shaped pattern.

[0019] Optionally, the filling machine comprises a ratchet wheel B, a pawl B and a switching plate;

[0020] The ratchet wheel B is installed on one side of the clamping wheel and coaxially arranged with the clamping wheel;

[0021] The pawl B is rotatably arranged on the filling machine on the side away from the channel through which the tablet strip passes, and the rotation shaft is provided with a torsional spring to enable the pawl B to downwardly engage with the ratchet wheel B;

[0025] In summary, the present application has at least one of the following beneficial technical effects:

[0026] 1. During the movement of the heat sealing device of the filling machine, the hot air device loosens the tablet strip, and then locks the rotation of the clamping wheel through the locking device, thereby improving the stability of the position of the tablet strip during the process, reducing the displacement error of the tablet strip, thereby improving the efficiency of the long-term work of the solid beverage for tablet strip filling, reducing the hot air port error, and improving the production quality;

DETAILED DESCRIPTION

[0038] The following will be described in detail in combination with the accompanying drawings Figures 1-5 The present application will be further described in detail.

[0039] The embodiments of the present application disclose a solid beverage filling machine auxiliary clamping device. Embodiment 1

[0040] Reference Figure 1 The auxiliary clamping device of the solid beverage filling machine comprises clamping wheels 1 and locking devices. The clamping wheels 1 are arranged in pairs, at least in one group, and are rotationally connected to the filling machine. The circumferential outer walls of the two clamping wheels 1 in one group are oppositely arranged and abut against the tablet strip to the other clamping wheel 1. In this embodiment, the clamping wheels 1 are arranged in one group. The clamping wheels 1 are arranged above the heat sealing device of the filling machine, and the tablet strip passes between the two clamping wheels 1. The circumferential outer wall of the clamping wheel 1 is made of rubber material, and the middle part is recessed to abut against the tablet strip. The clamping wheel 1 is provided with a locking device to limit the rotation of the clamping wheel 1 only when the heat sealing device of the filling machine moves upward.

[0041] The filling machine pours the solid beverage into the formed tablet strip and moves downward under the clamping of the heat sealing device. In the process of moving downward under the driving of the heat sealing device, the clamping wheel 1 clamps the tablet strip and rotates with the downward movement of the tablet strip. The rubber material of the clamping wheel 1 can effectively improve the stability of the downward movement of the tablet strip and reduce the relative displacement between the clamping wheel 1 and the tablet strip. At the same time, it can also position the path of the tablet strip. When the heat sealing device moves upward, the rotation of the clamping wheel 1 is limited by the locking device, thereby fixing the position of the tablet strip and reducing the displacement error of the tablet strip, so that the heat sealing position of the tablet strip is accurate in a long time of heat sealing processing, and the product quality is improved.

[0042] Reference Figure 1 And Figure 2 The locking device comprises a ratchet wheel A2, a pawl A3, a sliding block and a friction plate 5. The ratchet wheel A2 is installed on one side of the clamping wheel 1 and coaxially arranged with the clamping wheel 1. The sliding block 4 is vertically slidably connected to the filling machine and located below the ratchet wheel A2. The pawl A3 is installed on the sliding block 4 and arranged upward. The friction plate 5 is vertically arranged and installed on the vertical sliding frame of the heat sealing device of the filling machine. The friction plate 5 abuts against the side wall of the sliding block and can drive the sliding block to slide up and down. The sliding block can move up to the position where the pawl A3 engages with the ratchet wheel A2; the sliding block can move down to the position where the pawl A3 is separated from the ratchet wheel A2.

[0043] When the heat sealing device clamps and moves downward, the friction plate 5 abuts against the sliding plate and drives the sliding plate to move downward, thereby separating the pawl A3 from the ratchet wheel A2, so that the clamping wheel 1 can normally rotate and will not block the downward movement of the tablet strip. When the heat sealing device releases the tablet strip and moves upward, the friction plate 5 abuts against the sliding plate and drives the sliding plate to move upward, thereby engaging the pawl A3 with the ratchet wheel A2 to limit the rotation of the clamping wheel 1. At this time, the tablet strip cannot slide relative to the clamping wheel 1, thereby fixing the position of the tablet strip and improving the stability of the position of the tablet strip.

[0044] The implementation principle of the embodiment 1 of the present application is that: by using the relationship between the up-down movement of the heat sealing device and the movement of the tablet strip, the sliding plate abuts against the friction plate 5 when the heat sealing device moves downward, the pawl A3 is separated from the ratchet A2, and the clamping wheel 1 can rotate normally. When the heat sealing device moves upward, the sliding plate abuts against the friction plate 5 to drive the pawl A3 to engage with the ratchet A2, thereby locking the rotation of the clamping wheel 1, realizing the cooperation operation of locking and unlocking the clamping wheel 1 by the stroke of the up-down movement of the heat sealing device, and then reducing the displacement error of the tablet strip through the clamping wheel 1, improving the accuracy of the heat sealing position of the solid beverage tablet strip, and improving the product quality. Embodiment 2

[0045] With reference to Figure 3 and Figure 4 , the difference between the embodiment and the embodiment 1 is that: the side wall of the sliding block 4 towards the friction plate 5 is provided with a plurality of rollers 41, and the rotation axis of the roller 41 is horizontally arranged. The circumferential outer wall of the roller 41 is made of rubber material and abuts against the friction plate 5, and the circumferential outer wall of the roller 41 is provided with a strip-shaped pattern. The roller 41 rotates only when the sliding block 4 moves to the topmost end or the lowest end.

[0046] The implementation principle of the embodiment 2 of the present application is that: by the arrangement of the roller 41, the wear of the friction plate 5 and the sliding plate can be effectively reduced, and the stability of the sliding of the sliding plate driven by the friction plate 5 is improved by the rubber material of the roller 41, so that the roller 41 can stably roll after the sliding plate slides to the topmost end and the lowest end, and the service life of the friction plate 5 and the sliding block is improved. Embodiment 3

[0047] With reference to Figure 5 and Figure 6 , the difference between the embodiment 3 of the present application and the embodiment 1 is that: the locking device includes a ratchet B6, a pawl B7 and a switching plate 8. The ratchet B6 is installed on one side of the clamping wheel 1 and coaxially arranged with the clamping wheel 1. The pawl B7 is rotationally arranged on the filling machine and located on the side of the ratchet B6 away from the channel through which the tablet strip passes, and the rotation axis is provided with a torsional spring to make the pawl B7 downwardly engage with the ratchet B6. The switching plate 8 is installed on the vertical sliding frame body of the heat sealing device of the filling machine and vertically arranged. The pawl B7 is provided with a switching rod 71, the switching plate 8 is provided with a guide plate 81, and the guide plate 81 is located on the side of the switching rod 71 away from the ratchet B6. The bottom of the guide plate 81 is rotationally connected with an unlocking plate 811, the guide plate 81 is provided with a positioning plate 82, the rotation axis of the unlocking plate 811 is provided with a torsional spring, the unlocking plate 811 abuts against the positioning plate 82, and the position of the unlocking plate 811 is opposite to the switching rod 71. The abutment of the switching rod 71 and the unlocking plate 811 can make the pawl B7 downwardly rotate; before the heat sealing device of the filling machine moves to the lowest point, the switching rod 71 is separated from the guide plate 81.

[0048] The implementation principle of the embodiment 3 of the present application is that when the heat sealing device moves upward, the guide plate 81 does not abut against the switching rod 71, the unlocking plate 811 drives the unlocking plate 811 to rotate when abutting against the switching plate 8, and then the switching rod 71 passes through, the pawl B7 is always engaged with the ratchet B6, and the tea bag is stably fixed. When the heat sealing device moves downward, the unlocking plate 811 abuts against the switching rod 71 and drives the pawl B7 to rotate downward, and then the pawl B7 is separated from the ratchet B6, the fixation on the clamping wheel 1 is released, and then the switching rod 71 abuts against the guide plate 81 to keep the unlocking state of the ratchet B6.

[0049] The embodiments of the specific implementation are the preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
