Description

Technical Field

[0001] This utility model relates to the field of cold cutting technology, specifically to a cold cutting device. Background Technology

[0002] Cold cutting is a cutting method that uses techniques or methods that do not generate high temperatures during the cutting process, so that the material being cut retains its original material properties. The temperature does not rise drastically during the cutting process, and the temperature rise usually does not exceed 40 degrees Celsius.

[0003] Traditional cold cutting devices are formed by adding a cooling structure to ordinary cutting equipment. The cooling structure can include physical cooling structure or chemical cooling structure, such as using water spray to cool the cutting blade to achieve cold cutting.

[0004] While spraying water onto a cutting knife can cool it down, the water sprayed off the knife can damage objects, making it unsuitable for cooling food and other similar items, thus causing inconvenience. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cold cutting device that can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a cold cutting device, including a conveyor and a cutter that is lifted and slidably mounted above the conveyor. A water tank is installed at the bottom of the conveyor, and a water pump is installed in the inner cavity of the water tank. A return port is opened through the inner cavity at the top of the water tank. A filter screen with the same diameter as the return port is detachably installed in the return port. The cooling and cleaning assembly includes cooling seats fixedly mounted above the conveyor and located on both sides of the cutter. Each cooling seat has a cooling cavity that communicates with the output end of the water pump. A return pipe is connected to the other end of each cooling seat, with one end communicating with the cooling cavity and the other end extending into the return port. The outer wall of each cooling seat has a slot that penetrates the cooling cavity. A cleaning rod that is rotatably mounted in the slot and fits against the lower edge of the slot and the corresponding cutter is mounted in the slot.

[0008] Furthermore, a base is fixedly installed on one side of the conveyor, and a lifting slide groove is opened through the inner cavity on the outer wall of the base. A lifting cylinder with its output end extending into the base is fixedly installed on the top of the base.

[0009] Furthermore, the output end of the lifting cylinder is vertically fixedly connected to a connecting rod that slides through the lifting groove, and a knife holder is installed at the end of the connecting rod.

[0010] Furthermore, the cutter is slidably mounted on the bottom of the cutter holder, and a fastening screw is installed between the cutter and the cutter holder.

[0011] Furthermore, the outer wall of the water tank is provided with a baffle that is fixedly connected to one end of the filter screen, and a handle is installed on the side of the baffle away from the filter screen.

[0012] Furthermore, one end of the water tank has an inlet and a outlet distributed vertically through the inner cavity, and both the inlet and outlet are fitted with sealing caps.

[0013] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0014] 1. Cleaning rods are set on both sides of the cutting path of the cutter to make rolling contact with the cutter. The cleaning rods are rotatably installed in the slots in the corresponding cooling seat. They can make rolling contact with the surface of the cutter during the upward movement of the cutter after cutting the object, scraping off the cutting debris remaining on the surface of the cutter, improving the cleanliness of the cutter surface, and thus improving the cutting effect of the cutter.

[0015] 2. A circulating water circuit connected to the water tank is set in the cooling base, which can cool the cleaning rod, thereby reducing the temperature of the cutter. At the same time, it can also return the scraped debris to the water tank, and collect it after being filtered by the filter screen, which facilitates the water pump to circulate water.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1

[0029] Reference Figure 1-4 This is the first embodiment of the present invention, disclosing a cold cutting device, including a conveyor 1 and a cutter 25 that is lifted and slidably mounted above the conveyor 1. A water tank 3 is installed at the bottom of the conveyor 1, and a water pump is installed in the inner cavity of the water tank 3. The water pump is a submersible pump, suitable for long-term placement in the water tank 3. A return port 31 is opened through the inner cavity at the top of the water tank 3. A filter screen 32 with the same diameter as the return port 31 is detachably installed in the return port 31. Sliding grooves are opened on the two opposite inner sidewalls of the return port 31. The two opposite outer sides of the filter screen 32 are slidably inserted into the corresponding sliding grooves to achieve stable insertion of the filter screen 32. The cooling and cleaning components include cooling seats 4 fixedly mounted above the conveyor 1 and located on both sides of the cutter 25. Figure 1It can be seen that the cooling base 4 is vertically fixed to the side wall of the base 2 at one end. Each cooling base 4 has a cooling chamber 41 connected to the output end of the water pump. The cooling chamber 41 is used to store cooling water. The height of the cooling water is lower than the height of the top of the corresponding cleaning rod 43 to prevent the cooling water from leaking out from the slot 42 at the top of the cleaning rod 43. At the same time, it is higher than the height of the bottom of the cleaning rod 43 to ensure that the cleaning rod 43 can contact the cooling water in the cooling chamber 41. During the rotation of the cleaning rod 43, it achieves its own overall cooling. The other end of the cooling base 4 is connected to a return pipe 44 with one end connected to the cooling chamber 41 and the other end extending into the return port 31. The 44 is positioned at the bottom of the cooling chamber 41 to prevent the cooling water at the bottom of the cooling chamber 41 from being unable to return through the return pipe 44. The outer wall of the cooling seat 4 is provided with slots 42 that penetrate the cooling chamber 41. A cleaning rod 43 is rotatably installed in the slot 42, which is in contact with the lower edge of the slot 42 and the corresponding cutter 25. During the rotation, the cleaning rod 43 can stick the object debris attached to the surface of the cutter 25 to itself and carry it into the cooling chamber 41 by rotation. When it passes the lower edge of the slot 42, the object debris attached to the surface of the cleaning rod 43 is scraped off and stored in the cooling chamber 41. It is eventually carried out of the cooling chamber 41 with the circulation of cooling water.

[0030] Example 2

[0031] Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a base 2 is fixedly installed on one side of the conveyor 1. A lifting groove 21 is formed through the inner cavity of the outer wall of the base 2. A lifting cylinder 22 with its output end extending into the base 2 is fixedly installed on the top of the base 2. When the cutter 25 descends to contact the conveyor belt on the conveyor 1, the lifting cylinder 22 descends to the bottom of the lower groove 21. The lifting cylinder 22 limits the descent height of the cutter 25 to prevent excessive descent from damaging the conveyor 1. A connecting rod that slides through the lifting groove 21 is vertically fixedly connected to the output end of the lifting cylinder 22. 23. A blade holder 24 is installed at the end of the connecting rod 23. The cutter 25 is slidably installed at the bottom of the blade holder 24, and a fastening screw 26 is installed between the cutter 25 and the blade holder 24 for easy disassembly and replacement of the cutter 25. A baffle 33 is provided on the outer wall of the water tank 3 and fixedly connected to one end of the filter screen 32. A handle 34 is installed on the side of the baffle 33 away from the filter screen 32. A water inlet 35 and a drain 36 are provided at one end of the water tank 3 through the inner cavity. Both the water inlet 35 and the drain 36 are fitted with sealing caps for easy periodic replacement of the water in the water tank 3. The water pump input end is connected to the inner cavity of the water tank 3, and a water supply pipe 45 is connected between the water pump output end and the cooling cavity 41.

[0032] The remaining structure is the same as that in Example 1.

[0033] The workflow of this utility model is as follows:

[0034] First, place the object to be cut on the conveyor 1 and start the conveyor 1 to move the object at a constant speed. When the object moves to below the cutter 25, start the lifting cylinder 22, which drives the cutter holder 24 and the cutter 25 to descend via the connecting rod 23 to cut the object. After cutting, the lifting cylinder 22 drives the cutter holder 24 and the cutter 25 to rise via the connecting rod 23. During the rising process, the cutter 25 will contact the cleaning rods 43 on both sides, which will force the cleaning rods 43 to rotate. Since the cleaning rods 43 are immersed in the corresponding cooling chamber 41, the cleaning rods 43 are kept at a low temperature. By rolling the cleaning rods 43 on both sides of the cutter 25, the temperature of the cutter 25 is reduced to achieve cold cutting.

[0035] Secondly, during the cutting process, some debris may stick to the surface of the cutter 25. When it comes into contact with the cleaning rod 43, the debris can be scraped off onto the surface of the cleaning rod 43 by the rolling friction resistance between them. The debris then enters the cooling chamber 41 as the cleaning rod 43 rotates. Since the cleaning rod 43 is attached to the lower edge of the groove 42 on one side of the cooling seat 4, water leakage in the cooling chamber 41 is prevented while the debris on the surface of the cleaning rod 43 is scraped off, leaving the debris in the cooling chamber 41. This keeps the cleaning rod 43 and the cutter 25 clean and tidy, making it convenient for continuous cutting of objects.

[0036] Finally, while the cutter 25 is raising and lowering to cut, the water pump located in the water tank 3 is started, supplying water to the cooling chamber 41 through the water supply pipe 45, and returning to the return port 31 at the top of the water tank 3 through the return pipe 44. While completing the circulation of cooling water in the cooling chamber 41, the debris that was originally stored in the cooling chamber 41 is flushed into the return port 31 at the top of the water tank 3. After being filtered by the filter screen 32, the debris is filtered and intercepted on the upper surface of the filter screen 32, while the cooling water passes through the mesh of the filter screen 32 and flows back into the water tank 3, realizing the recycling of cooling water. The filter screen 32 can be removed from the return port 31 for cleaning periodically.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
