DETAILED DESCRIPTION

[0024] The following will be combined with 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 of 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.

[0025] refer to Figure 1-6 A cold glue machine for preparing rubber tubes, comprising a base 1 and a glue barrel 101, wherein the base 1 is provided with a clamping assembly for clamping the glue barrel 101, and the clamping assembly comprises two clamping blocks 102, characterized in that an adjusting groove 103 is provided in the base 1, and a screw adjusting assembly for enabling the two clamping blocks 102 to clamp the glue barrel 101 is provided in the adjusting groove 103, and a locking groove 403 is provided in the locking groove 403 for locking a locking mechanism for locking the screw adjusting mechanism;

[0026] When the staff needs to clamp different types of glue barrels 101, they only need to rotate the screw adjustment assembly, and the screw adjustment assembly will drive the clamping block 102 to clamp the glue barrel. Since the screw adjustment assembly has self-locking properties, the screw adjustment assembly can clamp different types of glue barrels, thereby improving the application range of the cold glue machine.

[0027] Specifically, the screw adjustment assembly includes an adjusting screw 2 and two adjusting blocks 201. The adjusting screw 2 is arranged in the adjusting groove 103 and is slidably connected to the inner wall of the adjusting groove 103. The adjusting block 201 is a rectangular parallelepiped structure. The adjusting block 201 with a rectangular parallelepiped structure can better contact with the inner wall of the adjusting groove 103, thereby limiting the radial freedom of the adjusting block 201, and further preventing the adjusting screw 2 from rotating, thereby improving the stability of the movement of the screw adjustment assembly. In order to improve the stability of the movement of the adjusting block 201, guide grooves 302 are arranged on the inner walls of both sides of the adjusting groove 103, and guide blocks 303 are arranged on both sides of the two clamping blocks 102. The guide blocks 303 are slidably connected to the inner wall of the guide groove 302. By setting the guide blocks 303 and the guide grooves 302, the deviation of the adjusting block 201 during the movement can be avoided, thereby improving the stability of the movement of the adjusting block 201. At the same time, the guide blocks 303 and the guide grooves 302 can further limit the radial displacement of the adjusting block 201.

[0028] The adjusting block 201 is rotated and has two threaded sections, which are symmetrically arranged with the rubber tube as the center, and the two threaded sections rotate in opposite directions. The two adjusting blocks 201 are respectively threadedly connected to the two threaded sections and slidingly connected to the inner wall of the adjusting groove 103, and the two adjusting blocks 201 are symmetrically arranged. The two clamping blocks 102 are respectively arranged on the opposite sides of the two adjusting blocks 201. One end of the adjusting screw 2 passes through the side of the base 1 through the rotating groove 202 and extends to the outside of the base 1. The adjusting screw 2 extending to the outside of the base 1 through the rotating groove 202 has no threaded section and is rotatably connected to the inner wall of the rotating groove 202. The two symmetrically arranged adjusting blocks 201 can automatically help the staff find the center, thereby facilitating the staff to apply glue.

[0029] When the staff needs to clamp the glue barrel 101, they only need to rotate the adjusting screw 2, and the adjusting screw 2 will drive the two adjusting blocks 201 to move towards each other, thereby driving the clamping block 102 to clamp the glue barrel 101. Through the threaded connection, the cold glue machine can clamp any type of glue barrel 101. In order to improve the stability and firmness of the clamping, the end of the clamping block 102 away from the adjusting block 201 is designed to have an arc shape, and an anti-skid pad 204 is provided at the end of the clamping block 102 with the arc structure. The design of the arc structure can increase the contact area between the clamping block 102 and the glue barrel, thereby increasing the friction force and further improving the fixing effect (it should be noted here that the radius of the arc surface should be a large arc surface, so that different types of glue barrels can be clamped), and the anti-skid pad 204 can further increase the contact area between the clamping block 102 and the glue barrel, thereby increasing the fixing effect.

[0030] The anti-skid pad 204 can be made of rubber material. The rubber anti-skid pad 204 is compressible, which can prevent the rubber barrel 101 from being deformed due to excessive clamping force. At the same time, because the rubber anti-skid pad 204 is compressible, when the staff rotates the adjustment screw 2 to drive the clamping block 102 to clamp the rubber barrel 101, a pre-tightening force can be added, thereby enhancing the fixing effect of the screw adjustment component on the rubber barrel 101;

[0031] The two additional clamping blocks 102 can also be connected to the adjusting block 201 through a plurality of first elastic members 203. Since the first elastic member 203 is also compressible, deformation of the rubber barrel caused by excessive clamping force can be avoided, and it is also convenient for the staff to add pre-tightening force to improve the fixing effect of the screw adjusting assembly. At the same time, the first elastic member 203 also has a shock-absorbing function. When the cold glue machine is subjected to vibration, the first elastic member 203 can play a buffering role, so that the clamping block 102 can firmly clamp the rubber barrel 101. In order to facilitate the staff to install the first elastic member 203, a mounting groove 5 is provided on the side of the clamping block 102 close to the adjusting block 201, and a mounting column 501 is provided in the mounting groove 5. The first elastic member 203 is sleeved on the mounting column 501, and the mounting groove 5 and the mounting column 501 can provide the first elastic member 203 Accurate positioning and fixed position are convenient for staff to install. At the same time, the first elastic member 203 is sleeved on the installation column 501 to prevent the first elastic member 203 from being offset or misplaced after long-term use, thereby improving the stability of the screw adjustment assembly. The same structure can also be set on the side of the adjustment block 201 close to the clamping block 102 to further improve the stability. However, a gap should be left between the two installation columns 501 to facilitate staff to add pre-tightening force. In addition, the clamping block 102 is connected to the adjustment block 201 through a plurality of first elastic members 203. The strength of the plurality of first elastic members 203 is sufficient to support the clamping block 102, so that the clamping block 102 will not fall due to gravity, and the installation column 501 set on the side of the clamping block 102 opposite to the adjustment block 201 can further increase the connection strength.

[0032] In this embodiment, in order to facilitate the staff to rotate the adjusting screw 2, a handle 3 is provided on the side of the adjusting screw 2 away from the base 1, and a rubber sleeve 301 is provided on the handle 3, and the rubber sleeve 301 is provided with anti-slip texture. The provided handle 3 can help the staff to obtain a larger torque, thereby facilitating the staff to rotate the adjusting screw 2. The rubber sleeve 301 can provide a good grip and make the operator feel more comfortable. The anti-slip texture design can increase the friction between the fingers and the handle 3, and operate the adjusting screw 2 more stably, reducing the possibility of operating errors caused by hand slippage.

[0033] In this embodiment, in order to improve the self-locking property of the screw adjustment assembly, the locking mechanism includes a locking block 4, a second elastic member 401, a locking screw 402, and an extrusion block 404. The locking groove 403 is arranged on one side of the rotating groove 202, the locking block 4 is arranged in the locking groove 403, the locking block 4 is arranged in the locking groove 403, one end of the locking block 4 abuts against the adjusting screw 2, a sliding block 405 is provided on the locking block 4, and the sliding block 405 is slidably connected to the inner wall of the locking groove 403, one end of the second elastic member 401 abuts against a side of the locking groove 403 close to the rotating groove 202, the other end of the second elastic member 401 abuts against the sliding block 405, the extrusion block 404 is arranged on the side of the sliding block 405 away from the second elastic member 401, and the locking screw 402 is arranged on the side of the base 1 and abuts against the extrusion block 404.

[0034] When the staff needs to lock the screw adjustment assembly, they first hold the locking screw 402 and rotate it, and the locking screw 402 will move toward the locking block 4, thereby squeezing the extrusion block 404, and then the locking block 4 moves in the direction of compressing the second elastic member 401, and locks the side of the adjustment screw 2 in the rotating groove 202 to prevent the adjustment screw 2 from rotating, thereby improving the self-locking property of the screw adjustment assembly and increasing the stability of the clamping of the screw adjustment assembly.

[0035] In order to further increase the self-locking property of the screw adjustment assembly, the end of the locking block 4 close to the adjusting screw 2 can be designed to be an arc-shaped structure. The design of the arc-shaped structure can increase the contact area between the locking block 4 and the adjusting screw 2, thereby improving the self-locking property of the screw adjustment assembly. At the same time, an anti-slip pattern can be provided at one end of the arc-shaped structure to increase the friction and contact area, or an anti-slip pad can be added;

[0036] Working principle: When the staff needs to clamp the glue barrel 101, first hold the handle 3 and rotate it. The handle 3 will rotate with the adjusting screw 2, and the adjusting screw 2 will drive the two adjusting blocks 201 to move towards each other, thereby driving the clamping block 102 to clamp the glue barrel 101. Through the threaded connection, the cold glue machine can clamp any type of glue barrel 101.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
