Description

Technical Field

[0001] The utility model relates to the field of food processing equipment, in particular to a tart roller conveying and laminating machine with a novel sealing mechanism. Background Art

[0002] At present, the market demand for egg tarts is extremely large, so the demand for rolled tart sticks, an intermediate product in the egg tart production process, is also very large, and the traditional manual operation mode can no longer meet the market demand. In the prior art, automated production equipment is generally used to mass-produce tart sticks. According to the production process requirements, the production and processing process of tart sticks includes the following process: first, the cut tart sticks are placed in a tray, and then the tray is covered and wrapped with plastic wrap. This processing process is generally completed manually, which has the following shortcomings: First, due to the height difference between the tart stick conveyor belt and the workbench, after the tray is connected to the tart stick at the tail end of the tart stick conveyor belt, the staff needs to bend down to lift the tray and transfer it to the workbench, and then perform the film coating operation process. It takes a short time for the tray to be filled with a tray of tart sticks, so the labor intensity of the staff responsible for transferring the tray between the tart stick conveyor belt and the workbench is very high. Second, when the plastic wrap is manually wound, there is a problem that the length is difficult to accurately control, which will cause waste of plastic wrap, and the thickness of the plastic wrap is very thin and has self-adhesive properties. Very sharp scissors need to be used for manual cutting, which has certain safety hazards when used.

[0003] Due to the large production of tart sticks, each tray of tart sticks needs to be manually transferred, wrapped, and cut. The labor intensity is high, the amount of film used is difficult to control, and there are safety hazards when using scissors. Therefore, it is possible to consider developing a device that can automatically transport trays, automatically cover with plastic wrap, and automatically cut. For ease of operation, when automatically laminating, a film is applied on the upper and lower sides of the tray, and then the upper and lower films are sealed together. Therefore, it is necessary to develop a sealing mechanism that can seal the films on all sides of the tray. Utility Model Content

[0010] Furthermore, the lower cutter assembly includes a cutter seat connecting plate, a cutter seat, an optical axis connecting block, a heating wire and an insulating material. A piece of the insulating material is arranged on each of the cutter seat connecting plates on both sides of the lower film conveyor, and the heating wire is arranged between the two pieces of the insulating material.

[0011] Furthermore, the sealing and cutting mechanism includes a sealing and cutting mechanism bracket, an optical axis connecting plate, and a guide optical axis. The optical axis connecting plate can be floatingly arranged above the sealing and cutting mechanism bracket, one end of the guide optical axis is fixed on the optical axis connecting plate, and the other end can be guided and moved through the sealing and cutting mechanism bracket and then fixed on the optical axis connecting block of the lower cutter assembly, and the upper cutter assembly guide sleeve is on the guide optical axis.

[0012] Furthermore, the upper cutter driving part is an upper cutter pressing down cylinder, the cylinder body part of the upper cutter pressing down cylinder is fixed at the lower end of the sealing and cutting mechanism bracket, and the piston rod part is downward and fixes the upper cutter assembly; the lower cutter driving part is a lower cutter lifting cylinder, the cylinder body part of the lower cutter lifting cylinder is fixed at the upper end of the sealing and cutting mechanism bracket, and the piston rod part extends upward and fixes the optical axis connecting plate.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] An embodiment of a tart roller conveying and laminating machine with a novel sealing mechanism of the utility model:

[0029] The specific structure of the tart roller conveying laminating machine with a novel sealing mechanism of the utility model is as follows Figures 1 to 6 As shown, it includes a climbing conveyor 1, and a lower film conveyor 6 is arranged in series at the tail end of the climbing conveyor 1. An upper film conveyor 2 is arranged above the front half of the lower film conveyor 6, and a sealing mechanism is also arranged on the lower film conveyor. The sealing mechanism includes a side sealing mechanism 8 arranged in the middle section of the lower film conveyor 6 and a sealing and cutting mechanism 9 arranged in the rear half of the lower film conveyor 6. The sealing and cutting mechanism 9 can cut the film and seal the films at the front and rear ends of the pallet. The side sealing mechanism 8 is used to seal the films on both sides of the pallet.

[0030] The climbing conveyor 1 is provided with a conveyor belt 7 with baffles. The baffles arranged on the conveyor belt at intervals along the conveying direction of the conveyor can hold the pallet conveyed thereon, so that the pallet can be smoothly conveyed to the top and enter the lower film conveyor 6.

[0031] An upper film roll support 3 and a cling film flattening mechanism 5 are provided above the upper film conveyor 2, and a lower film roll support 4 is provided below the lower film conveyor 6. The rolled film used to supply the film to the upper film conveyor 2 is horizontally sleeved on the shaft of the upper film roll support 3, and the rolled film used to supply the film to the lower film conveyor 6 is horizontally sleeved on the shaft of the lower film roll support 4. The cling film flattening mechanism 5 is used to flatten the cling film drawn from the upper film roll support 3, and the lower film roll is flattened in the process of being conveyed forward by the lower film conveyor 6.

[0032] Initially, the end of the roll film on the upper roll film support 3 is wound around the lower conveying plane of the upper film conveyor 2, and the end of the roll film on the lower roll film support 4 is wound around the upper conveying plane of the lower film conveyor 6. As the upper film conveyor 2 and the lower film conveyor 6 move forward, the lower and upper sides of the pallet are coated with film.

[0033] The side sealing mechanism 8 includes a bracket 8-1 and a pressing plate 8-2. The bracket 8-1 is fixed to the side beams on both sides of the lower film conveyor 6 by screws through the longer vertical side of one side thereof, and its horizontal side extends inward, and the shorter vertical side on the other side of the horizontal side hangs downward. The pressing plate 8-2 is a straight plate, one end of which is rotatably hinged on the shorter vertical side of the bracket 8-1, and the other end hangs downward. Initially, the ends of the cling film on the upper film roll bracket 3 and the lower film roll bracket 4 are guided to the bottom of the pressing plate 8-2. The pressing plate 8-2 presses the upper and lower layers of cling film together by its own weight. When the conveying plane of the lower film conveyor 6 is uneven, the pressing plate 8-2 can also float upward around the hinge point to automatically adapt to the shape of the conveying plane to press the upper and lower layers of cling film on both sides of the tray together.

[0034] The tail end of the tart conveyor belt is close to the head end of the climbing conveyor 1, and the tail end of the climbing conveyor 1 is tilted upward. Therefore, the staff can sit at the tail end of the tart conveyor belt, hold a tray with full tarts, and directly place it at the head end of the climbing conveyor 1. The climbing conveyor 1 conveys the tray to the lower film conveyor 6. After the lower film conveyor 6 and the upper film conveyor 2 step forward for a distance, the upper and lower parts of the tray are covered with film. When the tray runs to the sealing and cutting mechanism 9, the sealing and cutting mechanism 9 acts to cut off the continuous film between the two trays.

[0035] The sealing and cutting mechanism 9 includes a sealing and cutting mechanism adjustment bracket 9-1, a sealing and cutting mechanism bracket 9-2, an optical axis connecting plate 9-3, a lower cutter lifting cylinder 9-4, an upper cutter pressing cylinder 9-5, a guide optical axis 9-6, an upper cutter assembly 9-7 and a lower cutter assembly 9-8.

[0036] The sealing and cutting mechanism bracket 9-2 is fixed to the base frame, the optical axis connecting plate 9-3 can be floated above the sealing and cutting mechanism bracket 9-2, and the upper cutter assembly 9-7 and the lower cutter assembly 9-8 can be floated below the sealing and cutting mechanism bracket 9-2. Specifically, one end of the guide optical axis 9-6 is fixed on the optical axis connecting plate 9-3, and the other end can be guided and moved through the sealing and cutting mechanism bracket 9-2, the upper cutter assembly 9-7 is guided and sleeved on the guide optical axis 9-6, and the lower cutter assembly 9-8 is fixed at the lower end of the guide optical axis 9-6.

[0037] The cylinder body of the upper cutter pressing cylinder 9-5 is fixed at the lower end of the sealing and cutting mechanism bracket 9-2, and the piston rod part is downward and fixes the upper cutter assembly 9-7. The cylinder body of the lower cutter lifting cylinder 9-4 is fixed at the upper end of the sealing and cutting mechanism bracket 9-2, and the piston rod part extends upward and fixes the optical axis connecting plate 9-3.

[0038] The working process of the sealing and cutting mechanism 9 to cut the film is as follows: the upper cutter pressing cylinder 9-5 extends downward, driving the upper cutter assembly 9-7 to move downward. At the same time, the lower cutter lifting cylinder 9-4 extends upward, driving the lower cutter assembly 9-8 to move upward. The two cutter assemblies act simultaneously to cut the film.

[0039] Among them, the upward lifting stroke of the lower cutter assembly 9-8 is equivalent to the thickness of the tray, so the film on the tray will be cut off at the upper edge of the tray. The advantages are: first, the pressure applied by the upper and lower cutters to the plastic wrap and the tart stick is uniform, and the two ends of the tart stick will not be deformed by a large pressure, ensuring that the unit weight of the intermediate product cut out when the tart stick is cut at equal intervals later. Second, when cutting at the upper edge of the tray, the upper and lower layers of plastic wrap are evenly stressed, and after cutting, the upper and lower plastic wraps will be together and not easy to crack.

[0040] It is understandable that in other embodiments, the lower cutter assembly can be omitted, and the cling film at the front and rear ends of the tray can be cut only by the downward movement of the upper cutter assembly, which will not affect the sealing effect of the utility model. In this case, the heating wire can also be arranged on the upper cutter assembly.

[0041] It should be emphasized that in order to achieve the function of cutting the cling film, a slit is left in the middle of the lower film conveyor 6. The width of the slit is suitable for only allowing the cutter in the lower cutter assembly 9-8 to pass through, and will not affect the smooth flow of the pallet on the lower film conveyor 6.

[0042] The function of the sealing and cutting mechanism adjusting bracket 9-1 is to adjust the height of the sealing and cutting mechanism bracket 9-2.

[0043] The function of the sealing and cutting mechanism 9 is not only to cut off the coating, but also to heat-seal the upper and lower layers of coating together. To achieve this function, the specific structure is as follows:

[0044] The lower cutter assembly 9-8 includes a cutter seat connecting plate 9-8-1, a cutter seat 9-8-2, an optical axis connecting block 9-8-3, a heating wire 9-8-4 and an insulating material 9-8-5. The lower end of the guide optical axis 9-6 is inserted into the optical axis connecting block 9-8-3, and a piece of insulating material 9-8-5 is provided on each of the cutter seat connecting plates 9-8-1 located on both sides of the lower film conveyor 6, and a heating wire 9-8-4 is provided between the two insulating materials 9-8-5.

[0045] The electric heating wire 9-8-4 is located at the upper end of the knife seat connecting plate 9-8-1. At the same time, the distance between the knife seat connecting plates on both sides of the lower film conveyor 6 is adapted to the length of the upper cutter assembly 9-7. When the upper and lower cutters are pressed together, the electric heating wire 9-8-4 is located at the upper and lower cutting and pressing positions, heating the cling film while pressing the cling film to fuse the cling film together and achieve a sealing effect.

[0046] The side sealing mechanism 8 is arranged between the upper film conveyor 2 and the sealing and cutting mechanism 9, so the cling film drawn from the upper film roll support 3 and the lower film roll support 4 is covered on the upper and lower sides of the tray, and then passes through the side sealing mechanism 8 to be sealed, and then passes through the sealing and cutting mechanism 9 to be cut and sealed at the front and back. Therefore, for a roll of cling film, it is only necessary to manually pull the end of the cling film to the bottom of the pressing plate 8-2 at the beginning, and no manual pulling is required in the subsequent process. The pressing plate does not rotate, and the cling film will not be wrapped around it, ensuring the continuity of the production process.

[0047] After the cling film on the front and back sides of the tray is firmly sealed by hot pressing sealing technology, the two sides of the tray to be sealed are sealed together under the action of the self-adhesiveness of the cling film and the deadweight of the pressing plate 8-2, which not only ensures that the upper and lower layers of cling film can be stably pressed together without separation after sealing, but also simplifies the structure of the sealing mechanism.

[0048] In this embodiment, the heat-pressing sealing and cutting of the cling film at the front and rear ends of the tray are performed simultaneously, and the displacement of the cutter assembly during cutting also provides pressure for the heat sealing.

[0049] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
