Description

Technical Field

[0001] The utility model relates to a reciprocating mobile single-film point sealing device for a filling and sealing machine. Background Art

[0002] At present, for the single-film point sealing device of a filling and sealing machine, usually a mechanical device is used to take out a single film from the bottom outlet of a storage rack, then turn it 180 degrees, and then place the single film on the cup mouth of a plastic cup in a mold located below. Then, a point sealing unit seals the single film to the cup mouth of the plastic cup.

[0003] However, the applicant has found that since the single film needs to follow the mechanical device to turn 180 degrees, during the turning process, under the influence of air resistance, the single film may be skewed and unable to coincide with the cup mouth, or even the single film may completely deviate and break away from the cup mouth, which will cause the cup mouths of these plastic cups to be unable to be sealed smoothly and become waste products.

[0004] To solve this problem, the above technology needs to be improved. Content of the Utility Model

[0005] The purpose of the utility model is to provide a reciprocating mobile single-film point sealing device for a filling and sealing machine, which can accurately place a single film on the cup mouth of a plastic cup. The adopted technical solution is as follows:

The film storage device and the point sealing mechanism are respectively installed on the frame and are sequentially distributed along the longitudinal direction of the frame. It is characterized in that: the reciprocating mobile single-film point sealing device further comprises a reciprocating mobile single-film transfer mechanism. The reciprocating mobile single-film transfer mechanism comprises a support seat, a picking and placing unit, two first lifting units, and two reciprocating mobile units. The two reciprocating mobile units are installed on the front and rear sides of the frame. Each reciprocating mobile unit has a first moving end that can reciprocate longitudinally along the frame. The two first lifting units correspond to the two reciprocating mobile units one by one. Each first lifting unit is installed on the first moving end of the corresponding reciprocating mobile unit.

The positioning frame is installed on the second moving ends of all the second lifting units, and the plurality of dot-sealing heads are respectively installed on the positioning frame. At least one vacuum suction hole capable of sucking a single film is respectively opened at the bottom ends of the dot-sealing heads.

[0009] In a preferred solution, the second lifting unit is a second cylinder.

[0010] In one solution, the reciprocating moving unit is a third cylinder.

[0011] In another solution, the reciprocating moving unit is an electric cylinder.

[0012] In a preferred solution, the picking and placing unit includes at least two vacuum suction cups communicated with an external vacuum pumping device. The bottom ends of the vacuum suction cups are respectively installed on a support base. The numbers of the vacuum suction cups and the dot-sealing heads are the same and correspond to each other one by one.

The plurality of spot-sealing heads 204 are respectively installed on the positioning frame 202. At least one vacuum suction hole 2041 for sucking the single film is respectively opened at the bottom end of each spot-sealing head 204. In this embodiment, the number of the second lifting units 203 is two.

[0021] As Figures 1-3 shown, in an alternative embodiment of the present application, the second lifting unit 203 is a second cylinder.

[0022] As Figures 1-3 shown, in an alternative embodiment of the present application, the reciprocating mobile unit 404 is a third cylinder.

[0023] In an alternative embodiment of the present application, the reciprocating mobile unit 404 is an electric cylinder.

[0024] As Figures 1-3As shown, in an alternative embodiment of the present application, the pick-and-place unit 402 includes at least two vacuum suction cups 4021 communicated with an external vacuum pumping device. The bottom ends of the vacuum suction cups 4021 are respectively mounted on the support base 401.

[0025] As Figure 1 As shown, in an alternative embodiment of the present application, the film storage device 3 has at least one film taking port 301 at the bottom (that is, each single film storage tank has a film taking port 301 at the bottom). The number of the vacuum suction cups 4021 of the pick-and-place unit 402 and the film taking ports 301 of the film storage device 3 is the same and they correspond to each other one by one.

[0026] As Figures 1-3 As shown, in an alternative embodiment of the present application, the dot capping mechanism 2 further includes a calibration and positioning mechanism 205. The calibration and positioning mechanism 205 includes two calibration and positioning units 2051. Each calibration and positioning unit 2051 includes a calibration cone block 20511 and a calibration conical groove rod 20512. The calibration cone blocks 20511 and the calibration conical groove rods 20512 of each calibration and positioning unit 2051 are respectively mounted on the support frame 201 and the positioning frame 202, and the calibration cone blocks 20511 and the calibration conical groove rods 20512 (the conical grooves) of the same calibration and positioning unit 2051 are oppositely arranged and can be inserted and calibrated with each other.

[0027] The following is Figures 1-3 to introduce the working process:

[0028] 1. Below the dot capping mechanism 2, the mold conveying mechanism of the filling and sealing machine (a device cooperating with the reciprocating single-film dot capping device of this embodiment, not shown in the figure) makes intermittent movements, continuously sending the molds below the dot capping mechanism 2. Each container in the mold is located directly below each dot capping head 204 and they correspond to each other one by one.

[0029] 2. The pick-and-place unit 402 of the reciprocating single-film transfer mechanism 4 is located directly below the film storage device 3. The two first lifting units 403 work to drive the support base 401 and the pick-and-place unit 402 to rise. Each vacuum suction cup 4021 of the pick-and-place unit 402 sucks a single film from the corresponding film taking port 301 respectively, and then the two first lifting units 403 work to drive the support base 401 and the pick-and-place unit 402 to descend back to the original position.

[0030] 3. The two reciprocating units 404 of the reciprocating single-film transfer mechanism 4 work to drive the two first lifting units 403 to move until the pick-and-place unit 402 is located directly below the dot capping mechanism 2.

[0031] 4. The two first lifting units 403 operate to drive the support base 401 and the picking and placing unit 402 to rise. Each vacuum suction cup 4021 of the picking and placing unit 402 sends a single film to the bottom of the corresponding point sealing head 204 respectively. The vacuum suction holes 2041 of the point sealing head 204 suck the single film. Then the two first lifting units 403 operate to drive the support base 401 and the picking and placing unit 402 to descend back to the original position.

[0032] 5. The two reciprocating movement units 404 of the reciprocating moving single film transfer mechanism 4 operate to drive the two first lifting units 403 to move until the picking and placing unit 402 is directly below the film storage device 3. At the same time, the two second lifting units 203 of the point sealing mechanism 2 operate to drive the positioning frame 202 and all the point sealing heads 204 to descend. Each point sealing head 204 places the sucked single film on the top opening of the container of the mold below. Then the vacuum suction holes 2041 stop working, and the point sealing head 204 heat seals the single film to the top opening of the container. After the heat sealing is completed, the two second lifting units 203 operate to drive the positioning frame 202 and all the point sealing heads 204 to rise back to the original position, and the calibration cones 20511 and the calibration conical groove rods 20512 of the two calibration and positioning units 2051 are inserted and calibrated with each other.

[0033] In this way, the sealing of the container can be continuously completed.
