The guide groove 1401 is provided to guide the movement of the bearing seat 111, so as to ensure that the movement path of the bearing seat 111 is straight, and the movement stability of the bearing seat 111 is effectively improved.

[0030] Reference Figure 3 As shown, it can be understood that the bearing seat 111 is provided with a limiting portion 1111, which is arranged around the first roller body 110 and protrudes outward in the radial direction of the first roller body 110, that is, the limiting portion 1111 is a protruding structure arranged on the outer side wall of the bearing seat 111.

[0031] By setting the limiting portion 1111, when the bearing seat 111 moves up and down, the limiting portion 1111 can cooperate with the second roller body 120 or the top side wall inside the machine base 100, so as to limit the bearing seat 111 and prevent the bearing seat 111 from moving out of the limit position and affecting the installation of the bearing seat 111.

[0032] Reference Figure 4 and Figure 5As shown, it can be understood that the drive shaft 200 is rotatably connected to the machine base 100 through a bearing, and the drive shaft 200 is located above the first roller body 110, that is, the drive shaft 200 is located between the motor 130 and the first roller body 110. A transmission assembly 210 is provided between the drive shaft 200 and the bearing seat 111. The transmission assembly 210 includes a first bevel gear 211, a second bevel gear 212 and a first screw 213. The first bevel gear 211 is sleeved on the drive shaft 200, and the mounting block 140 is provided with a support platform 141. The support platform 141 is provided with a shaft sleeve 142. The second bevel gear 212 is rotatably connected to the shaft sleeve 142 and meshes with the first bevel gear 211.

[0033] Power transmission is achieved through the first bevel gear 211 and the second bevel gear 212 , which facilitates the user to accurately adjust the gap between the first roller body 110 and the second roller body 120 , thereby effectively improving the control accuracy of the drive shaft 200 .

[0034] The second bevel gear 212 is installed through the shaft sleeve 142 , eliminating the traditional bearing component, effectively simplifying the structure of the transmission assembly 210 , making it easier for users to assemble and use the transmission assembly 210 , and improving the assembly convenience of the transmission assembly 210 .

[0035] Reference Figure 4 As shown, it can be understood that the bearing seat 111 is connected to a cover plate 113 made of metal, a T-slot is formed between the bearing seat 111 and the cover plate 113, one end of the first screw 213 away from the second bevel gear 212 is snap-fitted with the T-slot, and the first screw 213 is threadedly fitted with the screw hole in the center of the second bevel gear 212.

[0036] By providing the cover plate 113, a T-shaped groove is formed between the cover plate 113 and the bearing seat 111 to engage with the head of the first screw rod 213. This can not only effectively improve the tightness of the connection between the first screw rod 213 and the bearing seat 111, but also facilitate the user to assemble the first screw rod 213, further improving the assembly convenience of the transmission assembly 210.

[0037] Reference Figure 5 As shown, it can be understood that a retaining spring 2121 is provided at the bottom end of the second bevel gear 212 , a gasket 143 is provided between the retaining spring 2121 and the support platform 141 , and the retaining spring 2121 and the gasket 143 are in conflict.

[0038] By setting the retaining spring 2121 and the gasket 143, the retaining spring 2121 abuts against the gasket 143, and the second bevel gear 212 can be limited in the vertical direction. The retaining spring 2121 cooperates with the first bevel gear 211 to limit the second bevel gear 212 from the upper and lower sides of the second bevel gear 212, thereby preventing the second bevel gear 212 from jumping in the radial direction when the transmission assembly 210 is working, ensuring the stable power transmission of the transmission assembly 210 and improving the installation stability of the second bevel gear 212.

[0039] Reference Figure 2 and Figure 4 As shown, it can be understood that the clamping member 300 includes an external gear 310, a synchronous chain 320 and a spring 330, the spring 330 is installed on the machine base 100 through a connecting rod, the external gear 310 is sleeved on the drive shaft 200, the synchronous chain 320 is located above the drive shaft 200 and meshes with the external gear 310, and the two ends of the synchronous chain 320 are respectively connected to the spring 330 and the bearing seat 111.

[0040] Specifically, a second screw 321 is provided at one end of the synchronous chain 320 away from the spring 330 , and the second screw 321 is rotatably connected to the synchronous chain 320 . The bearing seat 111 is provided with a fixing plate 112 , and the second screw 321 is fixedly connected to the fixing plate 112 .

[0041] One end of the synchronous chain 320 can be directly connected to the hook at the end of the spring 330, and the second screw 321 can be connected to facilitate the fixed installation of the other end of the synchronous chain 320, wherein the second screw 321 and the fixing plate 112 can be connected and fixed by screw connection, clamping connection, welding, etc., which will not be described in detail here. By providing the second screw 321, the connection structure of the synchronous chain 320 is simplified, and the assembly efficiency of the pressing member 300 is improved.

[0042] Reference Figure 4 As shown, it can be understood that the fixing plate 112 is provided with a through slot for the second screw rod 321 to pass through, and the second screw rod 321 is connected to two nuts 322 , which are respectively located on both sides of the fixing plate 112 and respectively abut against the fixing plate 112 .

[0043] By providing the through slot and the two nuts 322, the user can rotate the nut 322 to adjust the length of the second screw rod 321 passing through the through slot, and then adjust the pressure of the synchronous chain 320 on the first bevel gear 211. It is convenient for the user to adjust the pressure of the synchronous chain 320 to a suitable size, avoiding problems such as excessive pressure, low power transmission efficiency of the transmission assembly 210, or too little pressure, loose fit between the first bevel gear 211 and the second bevel gear 212, and further improving the control accuracy and fit of the transmission assembly 210.

[0044] Reference Figure 1 and Figure 3 As shown, it can be understood that the outer gear 310 is connected to the identification plate 311, and the outer wall of the identification plate 311 is extended toward the base 100 along the axial direction of the drive shaft 200. The outer wall of the identification plate 311 is provided with an identification portion, and the identification portion is located above the drive shaft 200. The identification portion is an arc-shaped curved scale. Along the vertical direction, the identification portion is bent and extended from the top of the identification plate toward one side of the identification plate 311.

[0045] By setting the marking part, compared with the traditional flat arc scale located on the side wall of the base 100, the marking part is located above the drive shaft 200, which is more convenient for users to observe and view, and the marking part rotates synchronously with the external gear 310, so the reading can be more precise and accurate, effectively improving the user experience.

[0046] It can be understood that the spring 330 of the clamping member 300 pulls the synchronous chain 320, so that the synchronous chain 320 presses the first bevel gear 211. When the user rotates the drive shaft 200, the first bevel gear 211 rotates synchronously and drives the bearing seat 111 to move up and down through the second bevel gear 212 and the first screw 213. At this time, the second screw 321 at one end of the synchronous chain 320 moves with the bearing seat 111. Under the tension of the spring 330, the synchronous chain 320 continues to press the outer gear 310. By setting the clamping member 300, the precision requirement of the transmission assembly 210 during assembly is effectively reduced without affecting the rotation of the first bevel gear 211. At the same time, the synchronous chain 320 presses the first bevel gear 211 to ensure that the first bevel gear 211 and the second bevel gear 212 are stably matched, avoiding problems such as misalignment and slipping, and effectively extending the service life of the shortbread machine.

[0047] Reference Figure 1 As shown, it can be understood that the drive shaft 200 can be connected to a drive motor 130 or other drive components to achieve automatic adjustment, or can be manually adjusted by operating the steering wheel 220. The operating steering wheel 220 is connected to one end of the drive shaft 200 through a central jack, that is, the operating steering wheel 220 is located on the side of the outer gear 310 away from the base 100 to drive the drive shaft 200 to rotate synchronously, and an eccentric handle is provided on the side of the operating steering wheel 220 away from the base 100.

[0048] By providing an operating rudder 220 with an eccentric handle, the user can manually control the rotation of the drive shaft 200. The operating rudder 220 is easy to assemble and requires little effort to operate, which can further improve the user experience and reduce the difficulty of controlling the drive shaft 200.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
