Description

Technical Field

[0001] The utility model relates to the technical field of profile bacon processing equipment, in particular to a bacon packaging and film coating device. Background Art

[0002] Bacon refers to a meat product made by curing meat and then baking and smoking it. Bacon has a strong anti-corrosion ability, can prolong its shelf life, and adds a unique flavor. It is deeply loved by consumers and is one of the indispensable commodities in the food sections of various shopping malls. Bacon usually needs to be packaged when sold in supermarkets. The traditional packaging method is to directly bag it in oil paper or plastic bags. This process is usually done manually, which is not only time-consuming and labor-intensive but also very easy to contaminate the bacon, ultimately shortening the shelf life of the food. Some bacon products are vacuum-packed to isolate the air. This is mainly done by vacuum laminating machines. However, this type of equipment also requires manual pre-packaging when vacuum packaging, and then uses vacuuming and heat sealing to achieve sealed packaging. Although it can effectively improve the shelf life of bacon, the degree of automation is low. A new type of packaging device is needed to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a bacon packaging and coating equipment, including a box body, a plurality of carriers connected in a transverse sliding manner inside the box body, the two sides of the carriers are connected to the driving mechanism built into the side wall of the box body, a plurality of clamping columns are connected in a longitudinal sliding manner between the frame plates on both sides of the carriers, electric heating plates are provided on the opposite surfaces of the clamping columns, the outer end surface of the outermost clamping column is longitudinally connected to the output end of the pushing cylinder on the carrier, a vacuum cover is provided above the opening of the box body to match it, and a plurality of sealing mechanisms are longitudinally provided in the vacuum cover, and the sealing mechanism is located between two adjacent carriers.

[0004] Furthermore, the sealing mechanism includes a sealing cylinder A, which is installed on one side of the top of the evacuation cover.

The sealing cylinder B is installed in the cover edge on the other side of the evacuation cover. The piston rod of the sealing cylinder B is provided with a number of splints B facing the splint A. The opposite surfaces of the two types of splints are provided with electric heating strips.

[0005] Furthermore, the driving mechanism includes a contraction cylinder, which is installed in a driving chamber inside the side wall of the box. The driving chamber is connected to the inside of the box through a transverse slide. The output end of the contraction cylinder is connected to the sliders on both sides of the carrier, and the sliders are slidably connected to the transverse slide.

[0006] Furthermore, the carriers and the drive mechanisms connected thereto are symmetrically distributed in the box, the contraction strokes of the symmetrical drive mechanisms are consistent, the contraction strokes of the outer drive mechanisms are greater than those of the inner ones, and when the number of carriers is an odd number, the middle carrier is directly fixed in the middle of the box.

[0007] Furthermore, hooks are symmetrically provided on the top of the evacuation cover, which are connected to the electric winch on the top beam through steel cables. The center of the top of the evacuation cover is connected to an exhaust pipe, which is connected to a vacuum pump. A sealing ring is provided at the bottom of the evacuation cover to match the opening of the box body.

[0008] Furthermore, longitudinal rods are connected between the frame plates on both sides of the carrier, and the through holes below the clamping columns are slidably connected to the longitudinal rods.

[0009] Furthermore, a blade is provided in the middle of the electric heating plate.

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] like Figures 1 to 4 As shown, a bacon packaging and laminating device includes a box body 1, in which a plurality of carriers 2 are connected in a transverse sliding manner. Both sides of the carriers 2 are connected to a drive mechanism built into the side wall of the box body 1. The drive mechanism includes a contraction cylinder 12, which is installed in a drive chamber 101 in the side wall of the box body 1. The drive chamber 101 is connected to the interior of the box body 1 through a transverse slide 102. The output end of the contraction cylinder 12 is connected to sliders 201 on both sides of the carrier 2, and the sliders 201 are slidably connected to the transverse slide 102. The carriers 2 and the drive mechanism connected thereto are symmetrically distributed in the box body 1. The contraction strokes of the symmetrical contraction cylinders 12 are consistent, and the contraction stroke of the outer contraction cylinders 12 is greater than that of the inner ones. This ensures that after contraction, the distance between adjacent carriers 2 remains consistent. When the number of carriers 2 is odd, the middle carrier 2 is directly fixed to the middle of the box body 1.

[0020] In this embodiment, a longitudinal rod 202 is connected between the frame plates on both sides of the carrier 2, and the longitudinal rod 202 is slidably connected to the through hole below the clamping column 3. An electric heating plate 4 is provided on the opposite surface of the clamping column 3, and a blade 401 is provided in the middle of the electric heating plate 4. The outer end face of the outermost clamping column 3 is longitudinally connected to the output end of the pushing cylinder 5 on the carrier 2, and a vacuum cover 6 is provided above the opening of the box body 1 to match it. A hook 601 is symmetrically provided on the top of the vacuum cover 6, and the hook 601 is connected to the electric winch 14 on the top beam 13 through a steel cable. The top center of the vacuum cover 6 is connected to the exhaust pipe 15, and the exhaust pipe 15 is connected to the vacuum pump. The bottom of the vacuum cover 6 is provided with a sealing ring 602 that matches the opening of the box body 1.

[0021] In this embodiment, several groups of sealing mechanisms are longitudinally provided in the evacuation cover 6, and the sealing mechanism is located between two adjacent carriers 2. The sealing mechanism includes a sealing cylinder A7, which is installed on one side of the top of the evacuation cover 6. The piston rod of the sealing cylinder A7 is provided with several splints A8. The through holes of the splint A8 are slidably connected to the piston rod of the sealing cylinder B9. The sealing cylinder B9 is installed in the cover edge on the other side of the evacuation cover 6. The piston rod of the sealing cylinder B9 is provided with several splints B10 facing the splint A8. The opposite surfaces of the two types of splints are provided with electric heating strips 11. When the sealing cylinder contracts, the electric heating strips 11 corresponding to the two types of splints fit together.

[0022] The working principle of this utility model is as follows:

[0023] like Figure 2 As shown, the heat shrink film (indicated by the dotted line) is folded in half and placed horizontally between adjacent electric heating plates 4. The push cylinder 5 is activated to press each clamping column 3, and then the electric heating plate 4 is activated. At this time, the electric heating plate 4 will fuse the clamped folded heat shrink film together, and the blade 401 will cut it into independent small bags. The shrink cylinders 12 are activated to drive each carrier 2 to move closer to the center. At this time, the small bags are squeezed apart due to the reduced spacing (see Figure 4 ), bacon is loaded into the open small bag through a fork or a manipulator. After loading, the shrink cylinder 12 is reset to tighten the small bags, and the electric winch 14 is started to lower the evacuation cover 6 to close it with the box body 1. Then the vacuum pump is turned on to evacuate the box body 1 so that the heat shrink film and the bacon are tightly fitted together. When a certain vacuum degree is reached, the sealing cylinders are started to clamp the electric heating strip 11 at the opening of the small bag, and then the electric heating strip 11 is started to heat-seal the small bag to complete the packaging and laminating of the bacon.

[0024] The utility model can clamp the folded heat shrink film by the cooperation between the clamping columns 3 and heat-seal it into independent small bags, then shrink the distance between the carriers 2 by the driving mechanism, squeeze the small bags open to bag the bacon, and finally close the vacuum cover 6 to vacuum and seal the small bags, thereby reducing the labor cost in the bacon packaging process and improving production efficiency.

[0025] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
