Description

Technical Field

[0001] This utility model relates to the field of straw cutting machine technology, specifically a straw cutting machine that is easy to change size. Background Technology

[0002] A straw, also known as a drinking straw, is a cylindrical, hollow plastic product. Its main function is to drink beverages from a cup. During the processing of straws, a straw cutting machine is needed to cut the extruded straw into the required size.

[0003] According to the patent application CN220840506 U, "This utility model relates to the field of straw production equipment technology and discloses a straw production cutting machine that facilitates size adjustment. It includes a housing, with a mounting plate fixedly installed on the front and rear inner walls of the housing. A thread-moving mechanism is provided between the mounting plate and the housing. A first seat hole and a second seat hole are provided on the top of the housing, with the first seat hole located to the right of the second seat hole. A motor is fixedly installed on the left side of the mounting plate, and an adjustment mechanism is provided between the motor and the housing. A limit mechanism is provided on the top of the housing. This utility model has the following advantages and effects: by providing the thread-moving mechanism, the straw body can be moved to a specified distance by a push plate, enabling the cutting of straw bodies of different lengths; by providing the adjustment mechanism and the cutting mechanism, the straw body can be precisely cut, thereby improving production quality."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model limits the straw body by setting a partition and pushes the straw with a push plate to achieve the function of cutting straws of different lengths. The electric telescopic rod pushes the cutter downward to cut the straw. However, in actual use, when the electric telescopic rod drives the cutter downward, the cutter will contact the top of the box. Since the cutter applies a downward force to the box, the cutter head, which is in frequent contact with the box, is easily damaged and the replacement frequency increases. Therefore, it is necessary to improve the straw cutting machine so that it is easy to change the size to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a straw cutting machine that is easy to change in size, so as to solve the problems mentioned in the background art.

[0015] Compared with the prior art, this utility model provides a straw cutting machine that is easy to change in size, and has the following beneficial effects:

[0016] 1. This straw cutting machine, which facilitates size adjustment, uses a cutting mechanism to change the straw cutting position and size by means of a scale on the top of the base and a moving cutting seat driven by a threaded rod. The machine also features a sponge pad inside the drawer to protect the downward-cutting blade from excessive force and damage from contact with hard objects, thus reducing the frequency of blade replacement.

[0017] 2. This straw cutting machine, which is easy to change in size, has a set placement and flattening component. During use, the set baffle can limit the placement of the straw on the inner side. The electric push rod drives the push plate to move and flatten the straw. By removing the pad, baffles with different spacing can be replaced according to the thickness of the straw, realizing the functions of limiting the placement and flattening the straw.

[0027] Example 1:

[0028] Please see Figures 1-4 This utility model provides a technical solution: a straw cutting machine that is easy to change size, including a scale base 1, a flattening component 3 is provided on the top of the scale base 1, and a cutting mechanism 2 is provided on the left side of the scale base 1.

[0029] The cutting mechanism 2 includes an adjusting cutting component 21 and a blade protection component 22, with the blade protection component 22 disposed inside and on the front of the adjusting cutting component 21.

[0030] Furthermore, the adjusting cutting assembly 21 includes a motor 211, which is fixedly installed on the right side of the scale base 1. A threaded rod 212 is fixedly installed on the left side of the drive shaft of the motor 211. A movable cutting seat 213 is installed on the external thread of the threaded rod 212. A limit rod seat 214 is slidably installed inside the movable cutting seat 213. A top frame 215 is provided on the top of the movable cutting seat 213. A cylinder 216 is fixedly installed on the top of the top frame 215. A cutting blade 217 is provided at the bottom of the output end of the cylinder 216, which facilitates the adjustment of the cutting size by adjusting the cutting assembly 21.

[0031] Furthermore, grooves are provided at corresponding positions of the scale base 1 and the movable cutting seat 213, and the movable cutting seat 213 is slidably installed inside the grooves provided inside the scale base 1, so that the movable cutting seat 213 can be moved under normal conditions.

[0032] Furthermore, the blade protection assembly 22 includes a drawer 221, which is slidably installed inside the movable cutting seat 213. A sponge pad 222 is provided inside the drawer 221. A locking block 223 is fixedly installed on the left side of the drawer 221. A limiting strip 224 and a limiting slide rod seat 228 are fixedly installed on the front of the movable cutting seat 213. A rack 225 is slidably installed on the outside of the limiting strip 224. An insert block 226 is fixedly installed on the right side of the rack 225. A slider 227 is fixedly installed on the top of the insert block 226. A spring 229 is provided on the outside of the limiting slide rod seat 228. A gear 2210 is rotatably installed on the front of the movable cutting seat 213. A screw block 2211 is fixedly installed on the front of the gear 2210, which facilitates the protection of the cutting blade 217 by the blade protection assembly 22.

[0033] Furthermore, the slider 227 is slidably mounted on the outside of the limiting slide block seat 228, and the gear 2210 meshes with the rack 225 to facilitate the movement of the rack 225.

[0034] Example 2:

[0035] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, it is further found that the placement and leveling component 3 includes a pad 31, which is slidably installed inside the scale base 1. A baffle 32 is fixedly installed on the top of the pad 31, and a mounting bracket 33 is fixedly installed on the right side of the scale base 1. An electric push rod 34 is fixedly installed on the inner right side of the mounting bracket 33, and a push plate 35 is fixedly installed on the left side of the electric push rod 34, so as to facilitate the placement and leveling of the straw by the placement and leveling component 3.

[0036] Furthermore, grooves are provided at corresponding positions of the scale base 1 and the pad 31, and the pad 31 is slidably installed inside the grooves provided inside the scale base 1, which facilitates the replacement of the baffle 32.

[0037] In actual operation, when this device is used, according to the thickness of the straw, the baffle 32 of the corresponding width is installed on the top of the scale base 1 via the pad 31. At this time, the electric push rod 34 is driven to move the push plate 35 to the left, flattening the end of the straw. The drive motor 211 causes the threaded rod 212 to rotate. At this time, the moving cutting seat 213 moves to the left under the restriction of the limiting rod seat 214, changing the position of the cutting blade 217 and changing the cutting size. The drive cylinder 216 causes the cutting blade 217 to move downward, thus cutting the straw. When the 7 is downward, it will be inserted into the inside of the sponge pad 222. When the sponge pad 222 is damaged after multiple cuts, rotate the screw block 2211 to make the gear 2210 drive the rack 225 to rotate. At this time, the insert block 226 will leave the locking hole block 223, and the drawer box 221 can be pulled out to replace the sponge pad 222. After inserting the drawer box 221 with the replaced sponge pad 222 into the inside of the movable cutting seat 213, rotate the screw block 2211 again. Using the elastic force of the spring 229, the insert block 226 can be inserted into the inside of the locking hole block 223 to limit and fix the drawer box 221.
