Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rubber band processing, more specifically, it relates to a kneading and pressing device for preparing rubber bands. BACKGROUND

[0002] A rubber band is a short circle made of rubber and latex, which is generally used to bind things together. During processing, the rubber and latex materials need to be mixed and kneaded first to make the materials more uniform and compact. During the kneading process, various additives are added to make the rubber more elastic. After the rubber and various additives are mixed completely, the rubber is cut and cut into rolls and molded using a grinding tool. After molding, the elasticity and hardness are improved through vulcanization. Finally, the rubber band is completed through the cutting process.

[0003] The existing kneading device mostly uses a kneading roller set to directly knead the mixed materials until the materials to be mixed are fully fused. During this process, various additives are added to the materials to improve the elasticity and change the color of the rubber. During the rotation of the kneading roller set, the materials and additives need to be kneaded multiple times to fuse due to different ratios of materials and additives. This requires workers to frequently cut the incompletely mixed materials stuck on the kneading roller set with a rubber knife, then stack them together and re-knead until the material mixing meets the requirements. This process is time-consuming and labor-intensive.

[0004] Therefore, a new solution is needed to solve this problem. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a kneading and pressing device for preparing rubber bands, which changes the space of material kneading through two side positioning plates to realize the stacking effect of incompletely mixed materials.

[0006] The above technical purpose of the utility model is achieved by the following technical solution: a kneading and pressing device for preparing rubber bands, comprising a body and a kneading roller set rotatably connected to the body, two side push plates slidably connected to the kneading roller set, a double screw rod rotatably connected to the bottom of the body, two drive plates fixedly connected to the bottom of the push plate, the drive plates respectively threaded to the two ends of the double screw rod, and a control assembly provided on the body to control the rotation of the double screw rod.

[0007] When the material on the kneading roller group needs to be added with various additives, the control assembly drives the bidirectional screw to rotate, thereby driving the driving plates connected with the two ends of the bidirectional screw to move, and since the bottoms of the two push plates are fixedly connected with the driving plates, the movement of the driving plates will drive the push plates to move, when the two push plates approach each other, the material on the kneading roller group will approach under the pushing of the push plates, thereby realizing the stacking of the material, and then the required additives are added and the two push plates are moved away from each other, at this time, the stacked material will gradually mix with the added additives, and then the process of the two push plates approaching and moving away from each other is repeated until the material and the additives are fully mixed, thereby realizing the stacking of the material without manual cutting and accelerating the stacking process of the material.

[0008] The control assembly comprises a motor arranged on the side wall of the machine body, and the output end of the motor is fixedly connected with the bidirectional screw.

[0009] By means of the motor, the bidirectional screw is positively rotated and reversely rotated, thereby realizing the mutual approach or mutual moving away of the two push plates, so as to realize the repeated stacking of the material.

[0010] The machine body is fixedly connected with a guide plate, the guide plate is arranged above the bidirectional screw, and the push plate is provided with a placing groove through which the guide plate passes.

[0011] By adopting the above technical scheme, the arrangement of the guide plate can avoid the adhesion of the falling material to the bidirectional screw and other components, and ensure the normal work of the two push plates, and the guide plate passes through the placing groove on the push plate and does not affect the normal work of the push plate.

[0012] The guide plate is arranged obliquely.

[0013] By adopting the above technical scheme, the oblique arrangement of the guide plate enables the material falling on the guide plate to slide from the high side to the low side under the influence of gravity, thereby facilitating the collection of the falling material.

[0014] The lowest side of the guide plate is upwardly folded to form a storage portion.

[0015] By adopting the above technical scheme, the material falling on the guide plate will move to the low place under the action of its own gravity, thereby enabling the falling material to gather in the storage portion, so as to facilitate the collection of the material by the staff.

[0016] The bottom of the machine body is provided with a sliding groove, the two driving plates are respectively slidably connected in the sliding groove through sliding blocks, and a limiting block is arranged on the side of the sliding groove away from the machine body.

[0017] By adopting the above technical scheme, since the two driving plates are respectively slidably connected to the sliding grooves through the sliding blocks, and the limiting blocks are arranged at the sides of the sliding grooves away from the machine body, the driving plates and the threads of the bidirectional screw rod can be prevented from falling off.

[0018] In summary, the utility model has the following beneficial effects:

[0019] With the aid of the driving assembly, the bidirectional screw rod is driven to rotate, thereby driving the driving plates threadedly connected to the two ends of the bidirectional screw rod to move, and further driving the push plates fixedly connected to the driving plates to approach each other, so as to realize the gathering of the materials on the kneading and pressing roller set.

[0020] II. With the aid of the guide plates arranged obliquely, the materials falling from the kneading and pressing roller set are gathered, so that the materials adhering to the machine body can be avoided to cause difficulty in cleaning in the later period. BRIEF DESCRIPTION OF DRAWINGS
